    Full Text Available Abstract Background Outcome quality indicators are rarely used to evaluate mental health services because most jurisdictions lack clinical data systems to construct indicators in a meaningful way across mental health providers. As a result, important information about the effectiveness of health services remains unknown. This study examined the feasibility of developing mental health quality indicators (MHQIs using the Resident Assessment Instrument - Mental Health (RAI-MH, a clinical assessment system mandated for use in Ontario, Canada as well as many other jurisdictions internationally. Methods Retrospective analyses were performed on two datasets containing RAI-MH assessments for 1,056 patients from 7 facilities and 34,788 patients from 70 facilities in Ontario, Canada. The RAI-MH was completed by clinical staff of each facility at admission and follow-up, typically at discharge. The RAI-MH includes a breadth of information on symptoms, functioning, socio-demographics, and service utilization. Potential MHQIs were derived by examining the empirical patterns of improvement and incidence in depressive symptoms and cognitive performance across facilities in both sets of data. A prevalence indicator was also constructed to compare restraint use. Logistic regression was used to evaluate risk adjustment of MHQIs using patient case-mix index scores derived from the RAI-MH System for Classification of Inpatient Psychiatry. Results Subscales from the RAI-MH, the Depression Severity Index (DSI and Cognitive Performance Scale (CPS, were found to have good reliability and strong convergent validity. Unadjusted rates of five MHQIs based on the DSI, CPS, and restraints showed substantial variation among facilities in both sets of data. For instance, there was a 29.3% difference between the first and third quartile facility rates of improvement in cognitive performance. The case-mix index score was significantly related to MHQIs for cognitive performance

    The aim of this project is to describe the quality of assessment data regularly collected in home and community, with techniques adapted from an evaluation of the quality of long-term care data in Canada. Data collected using the Resident Assessment Instrument - Home Care (RAI-HC) in Ontario and British Columbia (BC) as well as the interRAI Community Health Assessment (CHA) in Ontario were analyzed using descriptive statistics, Pearson's r correlation, and Cronbach's alpha in order to assess trends in population characteristics, convergent validity, and scale reliability. Results indicate that RAI-HC data from Ontario and BC behave in a consistent manner, with stable trends in internal consistency providing evidence of good reliability (alpha values range from 0.72-0.94, depending on the scale and province). The associations between various scales, such as those reflecting functional status and cognition, were found to be as expected and stable over time within each setting (r values range from 0.42-0.45 in Ontario and 0.41-0.43 in BC). These trends in convergent validity demonstrate that constructs in the data behave as they should, providing evidence of good data quality. In most cases, CHA data quality matches that of RAI-HC data quality and shows evidence of good validity and reliability. The findings are comparable to the findings observed in the evaluation of data from the long-term care sector. Despite an increasingly complex client population in the home and community care sectors, the results from this work indicate that data collected using the RAI-HC and the CHA are of an overall quality that may be trusted when used to inform decision-making at the organizational- or policy-level. High quality data and information are vital when used to inform steps taken to improve quality of care and enhance quality of life. This work also provides evidence that a method used to evaluate the quality of data obtained in the long-term care setting may be used to

    To determine whether geriatric triage decisions made using a comprehensive geriatric assessment (CGA) performed online are less reliable than face-to-face (FTF) decisions. Multisite noninferiority prospective cohort study. Two specialist geriatricians assessed individuals sequentially referred for an acute care geriatric consultation. Participants were allocated to one FTF assessment and an additional assessment (FTF or online (OL)), creating two groups-two FTF (FTF-FTF, n = 81) or online and FTF (OL-FTF, n = 85). Three acute care public hospitals in two Australian states. Admitted individuals referred for CGA. Nurse-administered CGA, based on the interRAI Acute Care assessment system accessed online and other online clinical data such as pathology results and imaging enabling geriatricians to review participants' information and provide input into their care from a distance. The primary decision subjected to this analysis was referral for permanent residential care. Geriatricians also recorded recommendations for referrals and variations for medication management and judgment regarding prognosis at discharge and after 3 months. Overall percentage agreement was 88% (n = 71) for the FTF-FTF group and 91% (n = 77) for the OL-FTF group. The difference in agreement between the FTF-FTF and OL-FTF groups was -3%, indicating that there was no difference between the methods of assessment. Judgements made regarding diagnoses of geriatric syndromes, medication management, and prognosis (with regard to hospital outcome and location at 3 months) were found to be equally reliable in each mode of consultation. Geriatric assessment performed online using a nurse-administered structured CGA system was no less reliable than conventional assessment in making clinical triage decisions. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Comparison of the first-generation Minimum Geriatric Screening Tools (MGST) and the third-generation interRAI Acute Care (interRAI AC). Based on a qualitative multiphase exchange of expert opinion, published evidence was critically analyzed and translated into a consensus. Both methods are intended for a multi-domain geriatric assessment in acute hospital settings, but each with a different scope and goal. MGST contains a collection of single-domain, internationally validated instruments. Assessment is usually triggered by care givers' clinical impression based on geriatric expertise. A limited selection of domains is usually assessed only once, by disciplines with domain-specific expertise. Clinical use results in improvement to screen geriatric problems. InterRAI AC, tailored for acute settings, intends to screen a large number of geriatric domains. Based on systematic observational data, risk domains are triggered and clinical guidelines are suggested. Multiple observation periods outline the evolution of patients' functioning over stay in comparison to the premorbid situation. The method is appropriate for application on geriatric and non-geriatric wards, filling geriatric knowledge gaps. The interRAI Suite contains a common set of standardized items across settings, facilitating data transfer in transitional care. The third-generation interRAI AC has advantages compared to the first-generation MGST. A cascade system is proposed to integrate both, complementary methods in practice. The systematic interRAI AC assessment detects risk domains. Subsequently, clinical protocols suggest components of the MGST as additional assessment. This cascade approach unites the strength of exhaustive assessment of the interRAI AC with domain-specific tools of the MGST.

    Background Although multiple studies have estimated the prevalence of neurological conditions in the general Canadian population, limited research exists regarding the proportion affected with these conditions in non-acute health care settings in Canada. Data from standardized clinical assessments based on the interRAI suite of instruments were used to estimate the prevalence of eight neurological conditions across the continuum of care including Alzheimer’s disease, Parkinson’s disease, epilepsy, traumatic brain injury, multiple sclerosis, cerebral palsy, Huntington’s disease, and amyotrophic lateral sclerosis. Methods Cohorts of individuals receiving care in nursing homes (N=103,820), home care (N=91,021), complex continuing care (N=10,581), and psychiatric hospitals (N=23,119) in Canada were drawn based on their most recent interRAI assessment within each sector for a six-month period in 2010. These data were linked to the Discharge Abstract Database and National Ambulatory Care Reporting System data sets to develop five different case definition scenarios for estimating prevalence. Results The conditions with the highest estimated prevalences in these care settings in Canada were Alzheimer’s disease and related dementias, Parkinson’s disease, epilepsy, and traumatic brain injury. However, there were notable cross-sector differences in the prevalence of each condition, and regional variations. Prevalence estimates based on acute hospital administrative data alone were substantially lower for all conditions evaluated. Conclusions The proportion of persons with neurological conditions in non-acute health care settings in Canada is substantially higher than is generally reported for the general population. It is essential for these care settings to have the expertise and resources to respond effectively to the strengths, preferences, and needs of the growing population of persons with neurological conditions.

    Conclusions: Different eating times can bring about changes on blood circulation index, E, and RAI. These changes show a certain tendency and coincide with the physiological factors that eating causes a rise of HR, an increase of systolic cardiac pump performance, and a reduction of peripheral vascular resistance.

    Background: The occurrence of adverse events (AEs) in care settings is a patient safety concern that has significant consequences across healthcare systems. Patient safety problems have been well documented in acute care settings; however, similar data for clients in home care (HC) settings in Canada are limited. The purpose of this Canadian study was to investigate AEs in HC, specifically those associated with hospitalization or detected through the Resident Assessment Instrument for Home Care (RAI-HC). Method: A retrospective cohort design was used. The cohort consisted of HC clients from the provinces of Nova Scotia, Ontario, British Columbia and the Winnipeg Regional Health Authority. Results: The overall incidence rate of AEs associated with hospitalization ranged from 6% to 9%. The incidence rate of AEs determined from the RAI-HC was 4%. Injurious falls, injuries from other than fall and medication-related events were the most frequent AEs associated with hospitalization, whereas new caregiver distress was the most frequent AE identified through the RAI-HC. Conclusion: The incidence of AEs from all sources of data ranged from 4% to 9%. More resources are needed to target strategies for addressing safety risks in HC in a broader context. Tools such as the RAI-HC and its Clinical Assessment Protocols, already available in Canada, could be very useful in the assessment and management of HC clients who are at safety risk. PMID:23968676

    Outcomes of adverse events in home care are varied and multifactorial. This study tested a framework combining two health measures to identify home care recipients at higher risk of long-term care placement or death within one year. Both measures come from the Resident Assessment Instrument-Home Care (RAI-HC), a standardized comprehensive clinical assessment. Persons scoring high in the Method for Assigning Priority Levels (MAPLe) algorithm and Changes in Health, End-stage disease, Signs and Symptoms (CHESS) scale were at the greatest risk of placement or death and more than twice as likely to experience either outcome earlier than others. The target group was more likely to trigger mood, social relationship, and caregiver distress issues, suggesting mental health and psychosocial interventions might help in addition to medical care and/or personal support services. Home care agencies can use this framework to identify home care patients who may require a more intensive care coordinator approach.

    The interRAI Acute Care instrument is a multidimensional geriatric assessment system intended to determine a hospitalized older persons' medical, psychosocial and functional capacity and needs. Its objective is to develop an overall plan for treatment and long-term follow-up based on a common set of standardized items that can be used in various care settings. A Belgian web-based software system (BelRAI-software) was developed to enable clinicians to interpret the output and to communicate the patients' data across wards and care organizations. The purpose of the study is to evaluate the (dis)advantages of the implementation of the interRAI Acute Care instrument as a comprehensive geriatric assessment instrument in an acute hospital context. In a cross-sectional multicenter study on four geriatric wards in three acute hospitals, trained clinical staff (nurses, occupational therapists, social workers, and geriatricians) assessed 410 inpatients in routine clinical practice. The BelRAI-system was evaluated by focus groups, observations, and questionnaires. The Strengths, Weaknesses, Opportunities and Threats were mapped (SWOT-analysis) and validated by the participants. The primary strengths of the BelRAI-system were a structured overview of the patients' condition early after admission and the promotion of multidisciplinary assessment. Our study was a first attempt to transfer standardized data between home care organizations, nursing homes and hospitals and a way to centralize medical, allied health professionals and nursing data. With the BelRAI-software, privacy of data is guaranteed. Weaknesses are the time-consuming character of the process and the overlap with other assessment instruments or (electronic) registration forms. There is room for improving the user-friendliness and the efficiency of the software, which needs hospital-specific adaptations. Opportunities are a timely and systematic problem detection and continuity of care. An actual shortage of

    Full Text Available The chronic diseases, comorbidities and rapidly changing needs of frail older persons increase the complexity of caregiving. A comprehensive, systematic and structured collection of data on the status of the frail older person is presumed to be essential in facilitating decision-making and thus improving the quality of care provided. However, the way in which an assessment is completed has a substantial impact on the quality and value of the results. This study examines the online completion of interRAI Home Care assessments, the possible causes for incomplete assessments and the consequences of these factors with respect to the quality of care received. Our findings indicate high nurse engagement and poor physician participation. We also observed the poor completion of items in predominantly medically- oriented sections characterized by, first, the fact that the assessors felt incapable of answering certain questions, second, the absence of required data or of a competent person to fill out the data, and third, the lack of tools necessary for essential measurements. The incompleteness of assessments has a clear negative influence on outcome generation. Moreover, without the added value of support outcomes, the improvement of care quality can be impeded and information technology can easily be seen as burdensome by the assessors. We have observed that multidisciplinary cooperation is an important prerequisite to establishing high-quality assessments aimed at improving the quality of care.

    Nursing homes are important locations for palliative care. Through comprehensive geriatric assessments (CGAs), evaluations can be made of palliative care needs of nursing home residents. The interRAI Palliative Care instrument (interRAI PC) is a CGA that evaluates diverse palliative care needs of adults in all healthcare settings. The evaluation results in Client Assessment Protocols (CAPs: indications of problems that need addressing) and Scales (e.g. Palliative Index for Mortality (PIM)) which can be used to design, evaluate and adjust care plans. This study aims to examine the effect of using the interRAI PC on the quality of palliative care in nursing homes. Additionally, it aims to evaluate the feasibility and validity of the interRAI PC. This study covers phases 0, I and II of the Medical Research Council (MRC) framework for designing and evaluating complex interventions, with a longitudinal, quasi-experimental pretest-posttest design and with mixed methods of evaluation. In phase 0, a systematic literature search is conducted. In phase I, the interRAI PC is adapted for use in Belgium and implemented on the BelRAI-website and a practical training is developed. In phase II, the intervention is tested in fifteen nursing homes. Participating nursing homes fill out the interRAI PC during one year for all residents receiving palliative care. Using a pretest-posttest design with quasi-random assignment to the intervention or control group, the effect of the interRAI PC on the quality of palliative care is evaluated with the Palliative care Outcome Scale (POS). Psychometric analysis is conducted to evaluate the predictive validity of the PIM and the convergent validity of the CAP 'Mood' of the interRAI PC. Qualitative data regarding the usability and face validity of the instrument are collected through focus groups, interviews and field notes. This is the first study to evaluate the validity and effect of the interRAI PC in nursing homes, following a methodology

    Background The interRAI Suite contains comprehensive geriatric assessment tools designed for various healthcare settings. Although each instrument is developed for a particular population, together they form an integrated health evaluation system. The interRAI Acute Care Minimum Data Set (interRAI AC) is tailored for hospitalized older persons. Our aim in this study was to translate and adapt the interRAI AC to the Belgian hospital context, where it can be used together with the interRAI Home Care (HC) and the interRAI Long Term Care Facility (LTCF). Methods A systematic, comprehensive, and rigorous 10-step approach was used to adapt the interRAI AC to local requirements. After linguistic translation by an official translator, five researchers assessed the translation for appropriate hospital jargon. Three researchers double-checked for translation accuracy and proposed additional items. A provisional version was converted into the three official languages of Belgium—Flemish, French, and German. Next, a multidisciplinary panel of nine experts judged item relevance to the Belgian care context and advised which country-specific items should be added. After these suggestions were incorporated into the interRAI AC, hospital staff from nine Flemish hospitals field-tested the tool in their practice. After evaluating field-test results, we compared the interRAI AC with Belgian versions of the interRAI HC and interRAI LTCF. Next, the Flemish, French, and German versions of the Belgian interRAI portfolio were harmonized. Finally, we submitted the Belgian interRAI AC to the interRAI organization for ratification. Results Eighteen administrative items of the interRAI AC were adapted to the Belgian healthcare context (e.g., usual residence, formal community services prior to admission). Fourteen items assessing the ‘informal caregiver’, and 17 items, including country-specific items, were added (e.g., advanced directive for euthanasia). Conclusions The interRAI AC was

    Full Text Available Indexing is one of the most important methods of content representation where by assigning descriptors to the documents, their subject content are made known. Since index and indexing are remarkably significant in information retrieval, its quality and evaluation and provision of criteria and standards had always been the mainstay of researchers in this field. Given the fact that Indexing is a complex process, offering definitions, principles and methods could be step towards optimal use of the information. The present study, while offering a capsule definition of index, will investigate the indexing evaluation criteria and would follow it up with a definition of indexing. Finally a number of standards in the field of indexing are presented and would make its conclusions.

    Full Text Available Introduction: Droughts are natural extreme phenomena, which frequently occur around the world. This phenomenon can occur in any region, but its effects will be more severe in arid and semi-arid regions. Several studies have highlighted the increasing of droughts trend around the world. The majority of studies in assessing the trend of time series are based on basic Mann-Kendall or Spearman's methods and no serious attention has been paid to the impact of autocorrelation coefficient on time series. However, limited numbers of studies have included the lag-1 autocorrelation coefficient and its impacts on the time series trend. The aim of this study was to investigate the trend of dry and wet periods in northwest of Iran using Mann-Kendall trend test with removing all significant autocorrelations coefficients based on SPI and RAI drought indices. Materials and Methods: Study area has a region of 334,000 square kilometers, with wet, arid and semiarid climate, located in the northwest of Iran. The rainfall data were collected from 39 synoptic stations with average rainfall of 146 mm as the minimum of Gom station, and the highest annual rainfall of 1687 mm, in the Bandaranzali station. In this study, Standardized Precipitation Index (SPI and Rainfall Anomaly Index (RAI were used for trend analysis of dry and wet periods. SPI was developed by McKee et al. in 1993 to determine and monitor droughts. This index is able to determine the wet and dry situations for a specific time scale for each location using rainfall data. RAI index was developed by Van Rooy in 1965 to calculate the deviation of rainfall from the normal amount of rainfall and it evaluates monthly or annual rainfall on a linear scale resulting from a data series. Then, correlation coefficients of time series of these drought indices with different lags were determined for check the dependence or independence of the SPI and RAI values. Finally, based on dependence or independence of the time

    Full Text Available Abstract Background The International Classification of Functioning, Disability and Health (ICF is embraced as a framework to conceptualize human functioning and disability. Health professionals choose measures to represent the domains of the framework. The ICF coding classification is an administrative system but multiple studies have linked diverse clinical assessments to ICF codes. InterRAI-HC (home care is an assessment designed to assist planning of care for patients receiving home care. Examining the relationship between the ICF and the interRAI HC is of particular interest because the interRAI assessments are widely used in clinical practice and research, are computerized, and uploaded to databases that serve multiple purposes including public reporting of quality in Canada and internationally. The objective of this study was to examine the relationship between the interRAI HC (home care assessment and the ICF. Specifically, the goal was to determine the proportion of interRAI HC items that can be linked to each of the major domains of the ICF (Body Function, Body Structure, Activities and Participation, and the Environmental Factors, the chapters and the specific ICF codes. Methods Three coders who were familiar with both the home care assessment and the ICF independently assigned ICF codes to inter-RAI HC items. Subsequently, a series of teleconference meetings were held to reach consensus on the primary code and much later consensus was used to finalize codes for additional items added to the interRAI HC. Results Following exclusion of administrative and diagnostic sections, 175 interRAI items were examined for potential assignment of codes. Of these 52 were assigned codes related to body function, 43 to activities and participation, 34 to environment, 1 to body structure, 17 to not coded, and 26 to not defined. Considering all 3-digit ICF codes, interRAI items addressed 43.2% of Body Function and 50.6% of Activities and Participation

    A methodology has been developed in order to evaluate the potential risk of drinking water for the health of the consumers. The methodology used for the assessment considered systemic and carcinogenic effects caused by oral ingestion of water based on the reference data developed by the World Health Organisation (WHO) and the Risk Assessment Information System (RAIS) for chemical contaminants. The exposure includes a hypothetical dose received by drinking this water according to the analysed contaminants. An assessment of the chemical quality improvement of produced water in the Drinking Water Treatment Plant (DWTP) after integration of membrane technologies was performed. Series of concentration values covering up to 261 chemical parameters over 5 years (2008-2012) of raw and treated water in the Sant Joan Despí DWTP, at the lower part of the Llobregat River basin (NE Spain), were used. After the application of the methodology, the resulting global indexes were located below the thresholds except for carcinogenic risk in the output of DWTP, where the index was slightly above the threshold during 2008 and 2009 before the upgrade of the treatment works including membrane technologies was executed. The annual evolution of global indexes showed a reduction in the global values for all situations: HQ systemic index based on RAIS dropped from 0.64 to 0.42 for surface water and from 0.61 to 0.31 for drinking water; the R carcinogenic index based on RAIS was negligible for input water and varied between 4.2×10(-05) and 7.4×10(-06) for drinking water; the W systemic index based on the WHO data varied between 0.41 and 0.16 for surface water and between 0.61 and 0.31 for drinking water. A specific analysis for the indexes associated with trihalomethanes (THMs) showed the same pattern. Copyright © 2015 Elsevier B.V. All rights reserved.

    This study assessed the validity of the Resident Assessment Instrument Minimum Data Set (RAI-MDS) Version 2.0 for diagnoses of diabetes and comorbid conditions in residents of long-term care facilities (LTCFs). Hospital inpatient, outpatient physician billing, RAI-MDS, and population registry data for 1997 to 2011 from Saskatchewan, Canada were used to ascertain cases of diabetes and 12 comorbid conditions. Prevalence estimates were calculated for both RAI-MDS and administrative health data. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated using population-based administrative health data as the validation data source. Cohen's κ was used to estimate agreement between the two data sources. 23,217 LTCF residents were in the diabetes case ascertainment cohort. Diabetes prevalence was 25.3% in administrative health data and 21.9% in RAI-MDS data. Overall sensitivity of a RAI-MDS diabetes diagnoses was 0.79 (95% CI: 0.79, 0.80) and the PPV was 0.92 (95% CI: 0.91, 0.92), when compared to administrative health data. Sensitivity of the RAI-MDS for ascertaining comorbid conditions ranged from 0.21 for osteoporosis to 0.92 for multiple sclerosis; specificity was high for most conditions. RAI-MDS clinical assessment data are sensitive to ascertain diabetes cases in LTCF populations when compared to administrative health data. For many comorbid conditions, RAI-MDS data have low validity when compared to administrative data. Risk-adjustment measures based on these comorbidities might not produce consistent results for RAI-MDS and administrative health data, which could affect the conclusions of studies about health outcomes and quality of care across facilities.

  4. The RAI DBS experiment with Olympus

    Science.gov (United States)

    Castelli, Enzo

    The Italian broadcasting network (RAI) has studied the development of a national DBS service in an effort to outline a proposal for a space segment configuration compatible with development of new services, including HDTV. Proposals so far considered feature the integration of RAI's channel on Olympus in a future operational system and after extensive experimental use. Contents of the experimental program are discussed, and need for a broadcasting standard which considers projected introduction of HDTV is noted. The debate between RAI and consumer electronic industries on the use of broadcasting standards is outlined. The position of RAI in the context of HDTV and DBS is defined and the issue of determining the most effective transmission standard during the experimental stage is raised. It is pointed out that, in the absence of new production facilities for HDTV, the maximum quality which MAC will yield will be that of PAL since programs must be produced in PAL and then converted into MAC. Two alternatives for strategy on the use of broadcasting standards for DBS are offered. Finally, technical experiments and a market survey are discussed.

    Full Text Available Introduction. Constipation is a common, bothersome, and potentially dangerous condition among nursing home (NH patients. Between 50 and 74% of NH patients use laxatives. Objective. To study prevalence and associations of laxative use and constipation using the comprehensive Norwegian version of the Resident Assessment Instrument for Long-Term Care Facilities. Methods. Cross-sectional study. Patients from 20 NH units were included. Logistic regression was used to analyze the results. Data collected in NHs might be clustered. Consequently, the multivariable models were tested against a mixed effects regression model to investigate variance both on the level of patients and on the level of NH units. Results. In all, 261 patients were included. The prevalence of constipation was 23.4%, and 67.1% used laxatives regularly. Balance problems, urinary incontinence, hypothyroidism, and Parkinson’s disease were associated with constipation. Reduced ability to communicate and number of drugs were associated with laxative use. Antidementia-drugs and being involved in activities 1/3 to 2/3 of daytime were protective factors for laxative use. Mixed effects analyses identified variance on the level of NH units as nonsignificant. Conclusion. Constipation and laxative use are common. Variance is mainly explained by different patient characteristics/health deficiencies. Hence, patients might benefit from individualized care to compensate for deficiencies.

    This study aimed to evaluate whether using the interRAI Palliative Care instrument (the interRAI PC) in nursing homes is associated with reduced needs and symptoms in residents nearing the end of their lives. A quasi-experimental pretest-posttest study using the Palliative care Outcome Scale (POS) was conducted to compare the needs and symptoms of residents nearing the end of their lives in the control and intervention nursing homes. Care professionals at the intervention nursing homes filled out the interRAI PC over the course of a year for all residents aged 65 years and older who were nearing the end of their lives. This intervention was not implemented in the control nursing homes. At baseline, POS scores in the intervention nursing homes were lower (more favorable) than in the control nursing homes on the items "pain", "other symptoms", "family anxiety", and the total POS score. Posttest POS scores for "wasted time" were higher (less favorable) than pretest scores in the intervention nursing homes. In the intervention nursing homes where care professionals did not have prior experience with the interRAI Long-Term Care Facilities (LTCF) assessment instrument (n = 8/15), total POS scores were lower (more favorable) at posttest. One year after introducing the interRAI PC, no reduction in residents' needs and symptoms were detected in the intervention nursing homes. However, reductions in needs and symptoms were found in the subgroup of intervention nursing homes without prior experience with the interRAI LTCF instrument. This may suggest that the use of an interRAI instrument other than the interRAI PC specifically can improve care. Future research should aim at replicating this research with a long-term design in order to evaluate the effect of integrating the use of the interRAI PC in the day-to-day practices at nursing homes.

  7. An assessment of grindability index of coal

    Grindability index of coal is an important technological parameter to understand the behaviour and assess the relative hardness of coals of varying ranks and grades during comminution. This is usually determined by Hardgrove Grindability Index (HGI), which involves requirement of a costly grinding equipment and accessories not readily available and affordable. Due to heterogeneous character of coals as regards maturity, petrological constituents, mineral impurities, etc. as well as mechanism of comminution render such determination rather difficult, leading to poor reproducibility and repeatability of HGI value, contrary to other analyses for coal characterisation. As such, it often gives misleading results to understand and explain properties emerging from other analyses and testing. In view of such problems, many attempts have been done in the past to develop correlation of HGI with simple analytical composition of coal. In this perspective a fresh attempt in arriving at a more reliable and reproducible correlation with proximate analysis alone is reported. Such an index termed as Statistical Grindability Index (SGI), may be found useful in assessment of coal behaviour not only in crushing and grinding of coal but also its friability vis-a-vis dust emission during comminution.

SMS is caused by interstitial 17p11.2 deletions, encompassing multiple genes and including the retinoic acid-induced 1 gene (RAI1, or by mutations in RAI1 itself. About 10% of all the SMS patients, in fact, carry an RAI1 mutation responsible for the phenotype. RAI1 (OMIM *607642 is a dosage-sensitive gene expressed in many tissues and highly conserved among species. Over the years, several studies have demonstrated that RAI1 (or its homologs in animal models acts as a transcriptional factor implicated in embryonic neurodevelopment, neuronal differentiation, cell growth and cell cycle regulation, bone and skeletal development, lipid and glucose metabolisms, behavioral functions, and circadian activity. Patients with RAI1 pathogenic variants show some phenotypic differences when compared to those carrying the typical deletion. They usually have lower incidence of hypotonia and less cognitive impairment than those with 17p11.2 deletions but more frequently show the behavioral characteristics of the syndrome and overeating issues. These differences reflect the primary pathogenetic role of RAI1 without the pathogenetic contribution of the other genes included in the typical 17p11.2 deletion. The better comprehension of physiological roles of RAI1, its molecular co-workers and interactors, and its contribution in determining the typical SMS phenotype will certainly open a new path

    Full Text Available Abstract Background The concept of frailty, a relative state of weakness reflecting multiple functional and health domains, continues to receive attention within the geriatrics field. It offers a summary of key personal characteristics, providing perspective on an individual’s life course. There have been multiple attempts to measure frailty, some focusing on physiologic losses, others on specific diseases, disabilities or health deficits. Recently, multidimensional approaches to measuring frailty have included cognition, mood and social components. The purpose of this project was to develop and evaluate a Home Care Frailty Scale and provide a grounded basis for assessing a person’s risk for decline that included functional and cognitive health, social deficits and troubling diagnostic and clinical conditions. Methods A secondary analysis design was used to develop the Home Care Frailty Scale. The data set consisted of client level home care data from service agencies around the world. The baseline sample included 967,865 assessments while the 6-month follow-up sample of persons still being served by the home care agencies consisted of 464,788 assessments. A pool of 70 candidate independent variables were screened for possible inclusion and 16 problem outcomes referencing accumulating declines and clinical complications served as the dependent variables. Multiple regression techniques were used to analyze the data. Results The resulting Home Care Frailty Scale consisted of a final set of 29 items. The items fall across 6 categories of function, movement, cognition and communication, social life, nutrition, and clinical symptoms. The prevalence of the items ranged from a high of 87% for persons requiring help with meal preparation to 3.7% for persons who have experienced a recent decline in the amount of food eaten. Conclusions The interRAI Home Care Frailty Scale is based on a strong conceptual foundation and in our analysis, performed as

    As a response to the proliferation of student-led protests and movements across the globe, we, as part of an international platform for young planning professionals- Urbego-, have developed the Youth Engagement Index (YEI) that assesses the involvement of young generations (ages 18-34) in urban governance. Designed to include, and be improved upon by, a collaboration with relevant actors such as local municipal governments, academia, nongovernmental youth organizations and the youth themselves, the YEI presents a unique opportunity to unveil weaknesses and opportunities for cities in terms of engaging their youth. Furthermore, the collaborative process highlights the value of having a recognized and engaged youth for future urban development and city life in general. (Author)

    Some previous studies have suggested increased cancer risk in hyperthyroid patients treated with radioactive iodine (RAI). It is unclear whether the excess cancer risk is attributable to hyperthyroidism, its treatment, or the shared risk factors of the two diseases. The objective was to assess cancer morbidity and mortality in hyperthyroid patients treated with either RAI or surgery. We identified 4334 patients treated surgically for hyperthyroidism in Finland during 1986-2007 from the Hospital Discharge Registry and 1814 patients treated with RAI for hyperthyroidism at Tampere University Hospital. For each patient, three age- and gender-matched controls were chosen. Information on cancer diagnoses was obtained from the Cancer Registry. The follow-up began 3 months after the treatment and ended at cancer diagnosis, death, emigration, or the common closing date (December 31, 2009). The overall cancer incidence was not increased among the hyperthyroid patients compared to their controls (rate ratio [RR], 1.05; 95% confidence interval [CI], 0.96-1.15). However, the risk of cancers of the respiratory tract (RR, 1.46; 95% CI, 1.05-2.02) and the stomach (RR, 1.64; 95% CI, 1.01-2.68) was increased among the patients. The overall cancer mortality did not differ between the patients and the controls (RR, 1.08; 95% CI, 0.94-1.25). The type of treatment did not affect the overall risk of cancer (hazard ratio for RAI vs thyroidectomy, 1.03; 95% CI, 0.86-1.23) or cancer mortality (hazard ratio, 1.04; 95% CI, 0.91-1.21). In this cohort of Finnish patients with hyperthyroidism treated with thyroidectomy or RAI, the overall risk of cancer was not increased, although an increased risk of gastric and respiratory tract cancers was seen in hyperthyroid patients. Based on this large-scale, long-term follow-up study, the increased cancer risk in hyperthyroid patients is attributable to hyperthyroidism and shared risk factors, not the treatment modality.

    Nursing homes are important locations for palliative care. High quality palliative care requires an evaluation of the different care needs of the nursing home residents. The interRAI Palliative Care instrument is a comprehensive assessment that evaluates the needs and preferences of adults receiving palliative care. This study aims to evaluate the usefulness, feasibility and face validity of the interRAI Palliative Care instrument. A qualitative study was conducted, based on the abductive reasoning approach. Fifteen nursing homes in Flanders (Belgium). Calls for participation were sent out by four umbrella organizations of Flemish nursing homes (Belgium) and at a national conference for nursing home staff. Nineteen care professionals (nurses, certified nursing assistants, psychologists, physiotherapists, quality coordinators and directors) of 15 nursing homes voluntarily agreed to participate in the study. During one year, care professionals evaluated the needs and preferences of all nursing home residents receiving palliative care by means of the interRAI Palliative Care instrument. Data on the usefulness, feasibility and face validity of the interRAI Palliative Care instrument were derived from notes, semi-structured interviews and focus groups with participating care professionals and were thematically analyzed and synthesized. Data were gathered between December 2013 and March 2015. In general, the interRAI Palliative Care (interRAI PC instrument) is a useful instrument according to care professionals in nursing homes. However, care professionals made a series of recommendations in order to optimize the usefulness of the instrument. The interRAI PC instrument is not always feasible to complete because of organizational reasons. Furthermore, the face validity of the instrument could be improved since certain items are incomplete, lacking, redundant or too complex. Findings highlight the importance of adapting the content of the interRAI Palliative Care

    Healthcare and social care environments are increasingly confronted with older persons with long-term care needs. Consequently, the need for integrated and coordinated assessment systems increases. In Belgium, feasibility studies have been conducted on the implementation and use of interRAI instruments offering opportunities to improve continuity and quality of care. However, the development and implementation of information technology to support a shared dataset is a difficult and gradual process. We explore the applicability of the UTAUT theoretical model in the BelRAI healthcare project to analyse the acceptance of the BelRAI web application by healthcare professionals in home care, nursing home care and acute hospital care for older people with disabilities. A structured questionnaire containing items based on constructs validated in the original UTAUT study was distributed to 661 Flemish caregivers. We performed a complete case analysis using data from 282 questionnaires to obtain information regarding the effects of performance expectancy (PE), effort expectancy (EE), social influence (SI), facilitating conditions (FC), anxiety (ANX), self-efficacy (SE) and attitude towards using technology (ATUT) on behavioural intention (BI) to use the BelRAI web application. The values of the internal consistency evaluation of each construct demonstrated adequate reliability of the survey instrument. Convergent and discriminant validity were established. However, the items of the ATUT construct cross-loaded on PE. FC proved to have the most significant influence on BI to use BelRAI, followed by SE. Other constructs (PE, EE, SI, ANX, ATUT) had no significant influence on BI. The 'direct effects only' model explained 30.8% of the variance in BI to use BelRAI. Critical factors in stimulating the behavioural intention to use new technology are good-quality software, interoperability and compatibility with other information systems, easy access to computers, training facilities

  19. Use of the interRAI CHESS scale to predict mortality among persons with neurological conditions in three care settings.

    John P Hirdes

    Full Text Available BACKGROUND: Persons with certain neurological conditions have higher mortality rates than the population without neurological conditions, but the risk factors for increased mortality within diagnostic groups are less well understood. The interRAI CHESS scale has been shown to be a strong predictor of mortality in the overall population of persons receiving health care in community and institutional settings. This study examines the performance of CHESS as a predictor of mortality among persons with 11 different neurological conditions. METHODS: Survival analyses were done with interRAI assessments linked to mortality data among persons in home care (n = 359,940, complex continuing care hospitals/units (n = 88,721, and nursing homes (n = 185,309 in seven Canadian provinces/territories. RESULTS: CHESS was a significant predictor of mortality in all 3 care settings for the 11 neurological diagnostic groups considered after adjusting for age and sex. The distribution of CHESS scores varied between diagnostic groups and within diagnostic groups in different care settings. CONCLUSIONS: CHESS is a valid predictor of mortality in neurological populations in community and institutional care. It may prove useful for several clinical, administrative, policy-development, evaluation and research purposes. Because it is routinely gathered as part of normal clinical practice in jurisdictions (like Canada that have implemented interRAI assessment instruments, CHESS can be derived without additional need for data collection.

    Evaluating the quality of care provided to older individuals is a key step to ensure that needs are being met and to target interventions to improve care. To this aim, interRAI's second-generation home care quality indicators (HCQIs) were developed in 2013. This study assesses the quality of home care services in six European countries using these HCQIs as well as the two derived summary scales. Data for this study were derived from the Aged in Home Care (AdHOC) study - a cohort study that examined different models of community care in European countries. The current study selected a sub-sample of the AdHOC cohort from six countries whose follow-up data were complete (Czech Republic, Denmark, Finland, Germany, Italy and the Netherlands). Data were collected from the interRAI Home Care instrument (RAI-HC) between 2000 and 2002. The 23 HCQIs of interest were determined according to previously established methodology, including risk adjustment. Two summary measures, the Clinical Balance Scale and Independence Quality Scale were also determined using established methodology. A total of 1,354 individuals from the AdHOC study were included in these analyses. Of the 23 HCQIs that were measured, the highest proportion of individuals experienced declines in Instrumental Activities of Daily Living (IADLs) (48.4 %). Of the clinical quality indicators, mood decline was the most prevalent (30.0 %), while no flu vaccination and being alone and distressed were the most prevalent procedural and social quality indicators, respectively (33.4 and 12.8 %). Scores on the two summary scales varied by country, but were concentrated around the median mark. The interRAI HCQIs can be used to determine the quality of home care services in Europe and identify areas for improvement. Our results suggest functional declines may prove the most beneficial targets for interventions.

    Full Text Available Facilities in an airport requires maintenance activity in order to achieve excellent quality level and able to support activities at the airport to avoid negative impacts, which is the declining quality of the facility that can lead to lower levels of the productivity carried out in an airport. Maintenance facilities at Bali's Ngurah Rai airport need the maintenance costs planning. To get proper maintenance actions,  the maintenance costs early stages of planning phase needs to develop a model of facility maintenance costs that can provide the maintenance costs estimates quickly and accurately. To produce a maintenance costs model we should identify the maintenance activities that exist at Ngurah Rai airport. Maintenance costs data used is within the last 5 years (2007-2011. Using the Cost Significant Model methode and the linear regression equation it showed that several of the facility maintenace significantly affect the facility maintenance costs in the Ngurah Rai Airport which is the cost of passenger terminal building maintenance (X6, the cost of runway maintenance (X1, the cost of taxiway maintenance (X2, the cost of air conditioning installation maintenance (X14, the cost of road maintenance (X4, the cost of vehicle parking maintenance (X5, and the cost of navigation and communication equipment maintenance (X10. There is 3  linear regression equation model which is 1 Y = 11873745878,77 + 0,993 X1 + 0,826 X2 + 0,334 X4 + 1,181 X6, 2 Y = -698840481,94 + 1,327 X1 + 1,716 X2 + 5,516 X5+ 3,060 X14, and 3 Y = 82110363478,07 + 1,013 X1 - 17,223X5 + 22,406 X10 - 12,035 X14. After doing the Cost Model Factor (CMF test to the three linear regression equation, the most accurate equation is linear regression equation Y = 82110363478,07 + 1,013 X1 - 17,223X5 + 22,406 X10 - 12,035 X14 that has the average ratio 0.006% of the actual cost, so it is the best facility maintenance cost model at Bali's Ngurah Rai Airport.

    Full Text Available Objective: To determine the factors associated with hand foot mouth disease (HFMD among children in day care center in Chiang Rai Province, Thailand. Methods: A community based case-control study was conducted to identify the factors associated with HFMD among the children under 6 years old who had been cared for in day care centers in Chiang Rai Province. A 47-item questionnaire had been developed and tested for validity and reliability before use. Index of item-objective congruence (IOC method was used to evaluate the quality of the questionnaire. The items of questionnaire consisted of various aspects including age, sex, history of vaccination, history of breastfeeding, history of treatment, etc. Data were analyzed in the logistic regression model at alpha = 0.05 to identify the association between variables. Results: Totally, 380 subjects (125 cases and 255 controls from 40 day care centers were recruited in the present study. Among the parents, 77.1% were female, 76.6% were aged 20–59 years old, 30.1% graduated at primary level, and 87.1% were Buddhist. Among the children, 53.8% were male, 58.7% were aged 3–4 years old, and 13.3% were overweight. After control for all possible confounding factors in the multiple logistic regression, two factors were associated with HFMD: children aged 5 years old (95% CI = 1.37–29.38, and children who had been breastfed for less than 6 months had a greater chance (1.97 times to develop HFMD than those who had a history of being breastfed ≥ 6 months (95% CI = 1.01–3.81. Conclusions: A specific prevention and control measure for HFMD should be developed and implemented. Breastfeeding young children for more than 6 months should be encouraged.

    The current trend in the management of low risk differentiated thyroid carcinoma is to follow less aggressive strategies. To assess the long-term morbidity and mortality outcomes of low-risk papillary thyroid carcinoma (PTC) patients undergoing minimal intervention. We retrospectively analyzed 137 patients with low-risk PTC (stage I: n=77; stage II: n=60). Of these patients, 107 (Group 1) had macro-PTC and underwent near-total thyroidectomy and received postoperatively 50mCi RAI. The remaining 30 patients (Group 2) had micro-PTC (<1cm) and were treated only by means of near-total thyroidectomy. The median follow-up for Group 1 patients was 10 years (range: 3-30). At 1-year evaluation, 8 patients of Group 1 had indeterminate or incomplete biochemical response, of whom 4 had also incomplete structural response to initial therapy. Only 1 of 4 patients with structural incomplete response underwent cervical lymph node dissection and then received an additional dose of 100mCi RAI. The remaining 7 patients received only an additional dose of 100mCi RAI. These patients have been continuously followed till the present time with no recurrences or deaths (median follow-up: 17.5 years; 3-30 years). At 15 years, 2 patients of Group 1 experienced biochemical recurrence and they received 100mCi RAI. Three patients of Group 2 experienced recurrence, with 2 receiving 50mCi RAI and 1 undergoing cervical lymph node dissection with 50mCi RAI. Patients with low-risk macro-PTC treated by means of near-total thyroidectomy without PCCLND and receiving postoperatively a low dose of 50mCi RAI have excellent long-term prognosis.

  14. Dietary regimens modify early onset of obesity in mice haploinsufficient for Rai1.

    Directory of Open Access Journals (Sweden)

    Joseph T Alaimo

    Full Text Available Smith-Magenis syndrome is a complex genomic disorder in which a majority of individuals are obese by adolescence. While an interstitial deletion of chromosome 17p11.2 is the leading cause, mutation or deletion of the RAI1 gene alone results in most features of the disorder. Previous studies have shown that heterozygous knockout of Rai1 results in an obese phenotype in mice and that Smith-Magenis syndrome mouse models have a significantly reduced fecundity and an altered transmission pattern of the mutant Rai1 allele, complicating large, extended studies in these models. In this study, we show that breeding C57Bl/6J Rai1+/- mice with FVB/NJ to create F1 Rai1+/- offspring in a mixed genetic background ameliorates both fecundity and Rai1 allele transmission phenotypes. These findings suggest that the mixed background provides a more robust platform for breeding and larger phenotypic studies. We also characterized the effect of dietary intake on Rai1+/- mouse growth during adolescent and early adulthood developmental stages. Animals fed a high carbohydrate or a high fat diet gained weight at a significantly faster rate than their wild type littermates. Both high fat and high carbohydrate fed Rai1+/- mice also had an increase in body fat and altered fat distribution patterns. Interestingly, Rai1+/- mice fed different diets did not display altered fasting blood glucose levels. These results suggest that dietary regimens are extremely important for individuals with Smith-Magenis syndrome and that food high in fat and carbohydrates may exacerbate obesity outcomes.

    The rapid expansion of unconventional natural gas production has triggered considerable public concerns, particularly regarding environmental and human health (EHH) risks posed by various chemical additives used in hydraulic fracturing (HF) operations. There is a need to assess the potential EHH hazards of additives used in real-world HF operations. In this study, HF additive and fracturing fluid data was acquired, and EHH hazards were assessed using an indexing approach. The indexing system analyzed chemical toxicological data of different ingredients contained within additives and produced an aggregated EHH safety index for each additive, along with an indicator describing the completeness of the chemical toxicological data. The results show that commonly used additives are generally associated with medium-level EHH hazards. In each additive category, ingredients of high EHH concern were identified, and the high hazard designation was primarily attributed to ingredients' high aquatic toxicity and carcinogenic effects. Among all assessed additive categories, iron control agents were identified as the greatest EHH hazards. Lack of information, such as undisclosed ingredients and chemical toxicological data gaps, has resulted in different levels of assessment uncertainties. In particular, friction reducers show the highest data incompleteness with regards to EHH hazards. This study reveals the potential EHH hazards associated with chemicals used in current HF field operations and can provide decision makers with valuable information to facilitate sustainable and responsible unconventional gas production.

    The aim of this study was to assess the appropriateness of using combined cell index (CCI) in the assessment of iron stores in blood donors. This index is calculated by the formula: red blood cell distribution width (RDW) × 104 × mean corpuscular volume (MCV)-1 × mean corpuscular haemoglobin (MCH)-1 . Ferritin measurement is a reliable method for estimating iron stores in blood donors. The sensitivity of red blood cell (RBC) parameters of complete blood count in detecting non-anaemic iron deficiency is significantly lower. Consequently, there were several attempts to increase the detection sensitivity by combining these parameters in different indices. This study included 1084 male and 792 female whole blood donors accepted for blood donation. For six RBC parameters with the highest level of correlation relative to ferritin [Hgb, MCV, MCH, mean corpuscular haemoglobin concentration (MCHC), RDW and CCI], diagnostic efficacy in the detection of iron depletion (ferritin stores in blood donors. © 2016 British Blood Transfusion Society.

  17. Meaning, Intention, and Responsibility in Rai Divinatory Discourse

    Directory of Open Access Journals (Sweden)

    Martin Gaenszle

    2016-10-01

    Full Text Available In speech act theory, as developed in ordinary language philosophy, the intentions of a speaker are regarded as decisive for the communication of meaning. This view, however, has been criticized by linguistic anthropologists as being culture-bound: in other cultural contexts with other notions of personhood the situations may be quite different. One case in point is that of divination, or divinatory speech, when the speaker is only the vehicle of another, higher authority. This paper examins the crucial part of a shamanic session (cintā among the Rai in eastern Nepal, when the shaman (jhā̃kri performs a divination (bakhyāune, diagnosing the state of the client household in Nepali language. The shaman is possessed by several divinities (such as Aitabare, Molu Sikari, who answer questions posed by the household and lineage elders. This raises a number of analytic issues: Who is held responsible for the diagnosis? What kind of language and imagery are used? And how is the meaning of the diagnosis—often expressed in ambivalent terms—established? The interpretation of textual and performative characteristics shows a more elaborate model of speech act participants is required to understand the complex agency involved. The divinities do have intentions, though it remains a collaborative task to read them properly.

    On 5 May 2014, a Mw 6.2 strike-slip earthquake occurred in the Mae Lao region of Chiang Rai province in Thailand. This earthquake took place in a region of known faults and caused substantial damage and injuries, although the region had been previously identified as having a relatively low earthquake hazard. Detailed field reconnaissance and deployment of a dense, temporary, network of broadband seismometers allowed details of the damage and its relationship to seismicity to be analyzed. The aftershock sequence associated with this main shock occurs on two well-defined trends, reflecting the two potential fault planes in earthquake mechanisms for the main shock and the majority of the aftershocks. The damage area was relatively large for an event of this magnitude, but building damage was largely limited to the primary rupture region, while liquefaction and other ground failure are spatially associated with the rupture area and along regional rivers. Stress modeling, combined with the time series and pattern of aftershock activity, leads us to propose that slip near the northern termination of the main shock rupture continued slightly onto a conjugate fault, helping to trigger the distinct pattern of two discrete, conjugate trends of aftershock activity that mirror the kinematics of the main shock fault mechanism.

    2015-12-01

    Full Text Available Aim of study: Diagnosing the degradation degree of forest ecosystems is the basis for restoration strategies. However, there is no literature documenting how to quantify the forest degradation degree by using synthetic indicators, also because there is not a widely accepted definition for "forest degradation" and "degraded forest". Although there are many definitions of forest degradation that converge on the loss of ecosystem services, still today there are no largely accepted methods that give operational guidance to help in defining it. In the present research, with the aim to assess the degree of forest degradation, an integrated index - FDI, Forest Degradation Index - was developed.Area of study: In this first application, the FDI was applied and validated at stand level in two different Mediterranean forest types in two different case studies: Madonie and Nedrodi regional Parks (Sicily, Italy. The first dominated by sessile oak [Quercus petraea (Matt. Liebl. subsp. austrotyrrhenica Brullo, Guarino & Siracusa], the second dominated by cork oak (Quercus suber L..Material and methods: FDI is a synthetic index structured starting from representative and relatively easily detectable parameters. Here, we propose a set of six indicators that should be assessed to determine the forest degradation: Structural Index (SI, Canopy Cover (CC, Natural Regeneration Density (NRD, Focal Species of Degradation (FSD, Coarse Woody Debris (CWD, and Soil Depth (SD. FDI, here proposed and discussed, has been based on a MCDA (Multi-Criteria Decision Analysis approach using the Analytic Hierarchy Process (AHP technique, and implemented in order to contribute in finding simple indicators useful for forest restoration purposes that have an eco-functional basis.Main results: An integrated index of forest degradation has been defined. FDI values are comprised in the closed interval [0, 10], ranging from class I (Higher ecological functionality to class IV (Lower

    Safe, sensitive, and non-invasive imaging methods to assess the presence, extent, and turnover of myocardial fibrosis are needed for early stratification of risk in patients who might develop heart failure after myocardial infarction. We describe a non-contrast cardiac magnetic resonance (CMR) approach for sensitive detection of myocardial fibrosis using a canine model of myocardial infarction and reperfusion. Seven dogs had coronary thrombotic occlusion of the left anterior descending coronary arteries followed by fibrinolytic reperfusion. CMR studies were performed at 7days after reperfusion. A CMR spin-locking T1ρ mapping sequence was used to acquire T1ρ dispersion data with spin-lock frequencies of 0 and 511Hz. A fibrosis index map was derived on a pixel-by-pixel basis. CMR native T1 mapping, first-pass myocardial perfusion imaging, and post-contrast late gadolinium enhancement imaging were also performed for assessing myocardial ischemia and fibrosis. Hearts were dissected after CMR for histopathological staining and two myocardial tissue segments from the septal regions of adjacent left ventricular slices were qualitatively assessed to grade the extent of myocardial fibrosis. Histopathology of 14 myocardial tissue segments from septal regions was graded as grade 1 (fibrosis area, 50% of field, n=1). A dramatic difference in fibrosis index (183%, PT1 (5.5%, P=0.12), and perfusion (-21%, P=0.05). A non-contrast CMR index based on T1ρ dispersion contrast was shown in preliminary studies to detect and correlate with the extent of myocardial fibrosis identified histopathologically. A non-contrast approach may have important implications for managing cardiac patients with heart failure, particularly in the presence of impaired renal function. Copyright © 2017 Elsevier Inc.

  3. Engineering index : a metric for assessing margin in engineered systems

    Energy Technology Data Exchange (ETDEWEB)

    Dolin, Ronald M.

    2002-01-01

    Inherent in most engineered products is some measure of margin or over design. Engineers often do not retain design and performance knowledge so they can quantify uncertainties and estimate how much margin their product possesses. When knowledge-capture and quantification is neither possible, nor permissible, engineers rely on cultural lore and institutionalised practices to assign nominal conditions and tolerances. Often what gets lost along the way is design intent, product requirements, and their relationship with the product's intended application. The Engineering Index was developed to assess the goodness or quality of a product.

    To compare the psychometric properties of the Chinese versions of Insomnia Severity Index (ISI), Athens Insomnia Scale (AIS) and Sleep Quality Index (SQI) for assessment and screening of insomnia in adolescents. This is a school-based survey of 1516 adolescents aged 12-19 years. Sleep-wake habit questionnaire, ISI, AIS, SQI, Epworth Sleepiness Scale (ESS) and 12-item General Health Questionnaire (GHQ-12) were administered. Insomnia Interview Schedule was used to assess the severity of insomnia symptoms and DSM-IV-TR diagnosis of insomnia. The Cronbach's alpha of ISI, AIS and SQI were 0.83, 0.81 and 0.65, respectively, and the 2-week test-retest reliability were 0.79, 0.80 and 0.72. All three scales had a 2-factor structure, and their scores were significantly correlated with sleep-wake variables, ESS and GHQ-12 scores, smoking and drinking habits, and academic performance. The areas under curve of ISI, AIS and SQI for detecting clinical insomnia were 0.85, 0.80 and 0.85, respectively. The optimal cut-offs for ISI, AIS and SQI were a total score of nine (sensitivity/specificity: 0.87/0.75), seven (sensitivity/specificity: 0.78/0.74) and five (sensitivity/specificity: 0.83/0.79), respectively. The Chinese versions of ISI, AIS and SQI are reliable and valid instruments. The ISI and AIS appear to have better psychometric properties than the SQI. Copyright © 2011 Elsevier B.V.

    Full Text Available IntroductionGovernments across Europe want to promote healthy and active aging, as a matter of both public health and economic sustainability. Designing policies focused on the most vulnerable groups requires information at the individual level. However, a measure of healthy and active aging at the individual level does not yet exist.ObjectivesThis paper develops the Selfie Aging Index (SAI, an individual-level index of healthy and active aging. The SAI is developed thinking about a tool that would allow each person to take a selfie of her aging status. Therefore, it is based entirely on self-assessed indicators. This paper also illustrates how the SAI may look like in practice.MethodsThe SAI is based on the Biopsychosocial Assessment Model (MAB, a tool for the multidimensional assessment of older adults along three domains: biological, psychological, and social. Indicators are selected and their weights determined based on an ordered probit model that relates the MAB indicators to self-assessed health, which proxies healthy and active aging. The ordered probit model predicts the SAI based on the estimated parameters. Finally, predictions are rescaled to the 0–1 interval. Data for the SAI development come from the Study of the Aging Profiles of the Portuguese Population and the Survey of Health, Aging, and Retirement in Europe.ResultsThe selected indicators are BMI, having difficulties moving around indoors and performing the activities of daily living, feeling depressed, feeling nervous, lacking energy, time awareness score, marital status, having someone to confide in, education, type of job, exercise, and smoking status. The model also determines their weights.ConclusionResults shed light on various factors that contribute significantly to healthy and active aging. Two examples are mental health and exercise, which deserve more attention from individuals themselves, health-care professionals, and public health policy. The SAI has the

    Drought is a critical issue, and it has a pressing, negative impact on agriculture, ecosystems, livelihoods, food security, and sustainability. The problem has been studied globally, but its regional or even local dimension is sometimes overlooked. Local-level drought assessment is necessary for developing adaptation and mitigation strategies for that particular region. Keeping this in understanding, an attempt was made to create a detailed assessment of drought characteristics at the local scale in Bangladesh. Standardized precipitation evapotranspiration (SPEI) is a new drought index that mainly considers the rainfall and evapotranspiration data set. Globally, SPEI has become a useful drought index, but its local scale application is not common. SPEI base (0.5° grid data) for 110 years (1901-2011) was utilized to overcome the lack of long-term climate data in Bangladesh. Available weather data (1955-2011) from Bangladesh Meteorology Department (BMD) were analyzed to calculate SPEI weather station using the SPEI calculator. The drivers for climate change-induced droughts were characterized by residual temperature and residual rainfall data from different BMD stations. Grid data (SPEI base ) of 26 stations of BMD were used for drought mapping. The findings revealed that the frequency and intensity of drought are higher in the northwestern part of the country which makes it vulnerable to both extreme and severe droughts. Based on the results, the SPEI-based drought intensity and frequency analyses were carried out, emphasizing Rangpur (northwest region) as a hot spot, to get an insight of drought assessment in Bangladesh. The findings of this study revealed that SPEI could be a valuable tool to understand the evolution and evaluation of the drought induced by climate change in the country. The study also justified the immediate need for drought risk reduction strategies that should lead to relevant policy formulations and agricultural innovations for developing

    2017-05-01

    To improve the forecasting accuracy and ensure reliable and stable operation of transformer, based on health index estimation model is proposed. The transformer data is divided into different levels and parts, so multi-parameter statistical analysis is carried on. The indicator system is scored and weighted by computing history data (inspection and maintenance, family defects, basic information and loading history) and condition data (such as routine test data). The condition parameters, which are classified on the component level, are scored and weighted, using statistical tools calculation. By using the statistical tools SPSS (statistical product and service solutions), multivariate statistical analysis was carried out. On the basis of studying the relationship between various parameters, a health evaluation model, which is based on contribution analysis, is presented. A condition-based evaluation tool, that quantifies power transformer degradation and clarifies the relationship between each health index, is put forward. Results are presented to verify the validity and feasibility of evaluating model and assessment algorithm. This paper provides a scientific method for the transmitting and transforming field.

    Peritonitis is one of the most common problems in general surgery practice with high mortality rate. One of the reasons for high mortality is that peritonitis affects the general condition and leads to complications causing multiple organ failure, renal failure, sepsis, and postoperative ventilatory support. Early prognostic evaluation of patients with peritonitis is desirable to select high-risk patients for intensive management and also to provide a reliable objective classification of severity and operative risk. Fifty cases with diagnosis of peritonitis coming to Government Medical College, Amritsar, were studied. Stratification of these patients was done according to Mannheim peritonitis index (MPI), and their outcome was examined. Mortality steadily increases with increase in MPI score. For patients with a score 27, it was 100% (P 27, it was 100% (P 24 h, organ failure on admission, female sex, and feculent exudate were found to be independently significant factors in predicting the mortality among the study population. For a score of 27, the sensitivity was 66.67%, specificity was 100%, and positive predictive value for mortality is 100% at an accuracy of 94%. This study proves that MPI scoring system is a simple and effective tool for assessing the morbidity and mortality in patients with peritonitis.

  18. Retinal image quality assessment through a visual similarity index

    Pérez, Jorge; Espinosa, Julián; Vázquez, Carmen; Mas, David

    2013-04-01

    Retinal image quality is commonly analyzed through parameters inherited from instrumental optics. These parameters are defined for 'good optics' so they are hard to translate into visual quality metrics. Instead of using point or artificial functions, we propose a quality index that takes into account properties of natural images. These images usually show strong local correlations that help to interpret the image. Our aim is to derive an objective index that quantifies the quality of vision by taking into account the local structure of the scene, instead of focusing on a particular aberration. As we show, this index highly correlates with visual acuity and allows inter-comparison of natural images around the retina. The usefulness of the index is proven through the analysis of real eyes before and after undergoing corneal surgery, which usually are hard to analyze with standard metrics.

    The BODE index (including body-mass index, airflow obstruction, dyspnoea, and exercise capacity) was an important contribution to the prognostic assessment of patients with chronic obstructive pulmonary disease (COPD). However, no study has assessed whether the risk of mortality predicted by the BODE index matches the observed mortality in different populations. We assessed the calibration of the BODE index, updated it to improve its calibration, and developed and validated a simplified index for use in primary-care settings. We included 232 patients from the Swiss Barmelweid cohort with longstanding and severe COPD and 342 patients from the Spanish Phenotype and Course of COPD cohort study who had had their first hospital admission due to moderate-to-severe COPD. In both cohorts we compared the observed 3-year risk of all-cause mortality with the risk predicted by the BODE index. We then updated the BODE index and developed a simplified ADO index (including age, dyspnoea, and airflow obstruction) from the Swiss cohort, and validated both in the Spanish cohort. Calibration of the BODE index was poor, with relative underprediction of 3-year risk of mortality by 36% in the Swiss cohort (median predicted risk 21.7% [IQR 12.7-31.7] vs 34.1% observed risk; p=0.013) and relative overprediction by 39% in the Spanish cohort (16.7% [12.7-31.7] vs 12.0%; p=0.035). The 3-year risk of mortality predicted by both the updated BODE (median 10.7% [8.1-13.8]) and ADO indices (11.8% [9.1-14.3]) matched the observed mortality in the Spanish cohort well (p=0.99 and p=0.98, respectively). Both the updated BODE and ADO indices could lend support to the prognostic assessment of patients with COPD in specialised and primary-care settings. Such assessment enhances the targeting of treatments to individual patients.

    Frailty is closely linked to health results. Frailty indexes (FI) and the Comprehensive Geriatric Assessment (CGA) are multidimensional tools. FI serve to quantitatively measure frailty levels. They have shown to have an excellent correlation with mortality. However, they are infrequently used in clinical practice. Given the need for new, more concise, and pragmatic FI, a new FI is proposed based on a CGA (Frail-VIG Index). A prospective, observational, longitudinal study was conducted, with cohort follow up at 12 months or death. Participants were patients admitted in the Geriatric Unit of the University Hospital of Vic (Barcelona, Spain) during 2014. Contrast of hypothesis log-rank for survival curves according to Frail-VIG index, and analysis of ROC curves were performed to assess prognostic capacity. A total of 590 patients were included (mean age=86.39). Mortality rate at 12 months was 46.4%. The comparative analysis showed statistically significant differences (P<.05) for almost all variables included in the Frail-VIG index. Survival curves also show significant differences (X 2 =445, P<.001) for the different Frail-VIG index scores. The area under the ROC curve at 12 months was 0.9 (0.88-0.92). An administration time of the Index is estimated at less than 10minutes. Results endorse the Frail-VIG index as a simple (as for contents), rapid (for administration time) tool, with discriminative (for situational diagnosis) and predictive capacity (high correlation with mortality).

  7. Structure and Function of the 5'-<' Exoribonuclease Rat1 and its Activating Partner Rai1

    The 5??3? exoribonucleases (XRNs) comprise a large family of conserved enzymes in eukaryotes with crucial functions in RNA metabolism and RNA interference1, 2, 3, 4, 5. XRN2, or Rat1 in yeast6, functions primarily in the nucleus and also has an important role in transcription termination by RNA polymerase II (refs 7-14). Rat1 exoribonuclease activity is stimulated by the protein Rai1 (refs 15, 16). Here we report the crystal structure at 2.2 A resolution of Schizosaccharomyces pombe Rat1 in complex with Rai1, as well as the structures of Rai1 and its murine homologue Dom3Z alone at 2.0 A resolution. The structures reveal the molecular mechanism for the activation of Rat1 by Rai1 and for the exclusive exoribonuclease activity of Rat1. Biochemical studies confirm these observations, and show that Rai1 allows Rat1 to degrade RNAs with stable secondary structure more effectively. There are large differences in the active site landscape of Rat1 compared to related and PIN (PilT N terminus) domain-containing nucleases17, 18, 19, 20. Unexpectedly, we identified a large pocket in Rai1 and Dom3Z that contains highly conserved residues, including three acidic side chains that coordinate a divalent cation. Mutagenesis and biochemical studies demonstrate that Rai1 possesses pyrophosphohydrolase activity towards 5? triphosphorylated RNA. Such an activity is important for messenger RNA degradation in bacteria21, but this is, to our knowledge, the first demonstration of this activity in eukaryotes and suggests that Rai1/Dom3Z may have additional important functions in RNA metabolism.

  8. The Shc family protein adaptor, Rai, negatively regulates T cell antigen receptor signaling by inhibiting ZAP-70 recruitment and activation.

    Directory of Open Access Journals (Sweden)

    Micol Ferro

    Full Text Available Rai/ShcC is a member of the Shc family of protein adaptors expressed with the highest abundance in the central nervous system, where it exerts a protective function by coupling neurotrophic receptors to the PI3K/Akt survival pathway. Rai is also expressed, albeit at lower levels, in other cell types, including T and B lymphocytes. We have previously reported that in these cells Rai attenuates antigen receptor signaling, thereby impairing not only cell proliferation but also, opposite to neurons, cell survival. Here we have addressed the mechanism underlying the inhibitory activity of Rai on TCR signaling. We show that Rai interferes with the TCR signaling cascade one of the earliest steps--recruitment of the initiating kinase ZAP-70 to the phosphorylated subunit of the TCR/CD3 complex, which results in a generalized dampening of the downstream signaling events. The inhibitory activity of Rai is associated to its inducible recruitment to phosphorylated CD3, which occurs in the physiological signaling context of the immune synapse. Rai is moreover found as a pre-assembled complex with ZAP-70 and also constitutively interacts with the regulatory p85 subunit of PI3K, similar to neuronal cells, notwithstanding the opposite biological outcome, i.e. impairment of PI-3K/Akt activation. The data highlight the ability of Rai to establish interactions with the TCR and key signaling mediators which, either directly (e.g. by inhibiting ZAP-70 recruitment to the TCR or sequestering ZAP-70/PI3K in the cytosol or indirectly (e.g. by promoting the recruitment of effectors responsible for signal extinction prevent full triggering of the TCR signaling cascade.

    Biotic indices are mainly aimed at assessing levels of deterioration caused by chemical or organic pollution. However, no biotic index to date has been developed to detect impacts of alien species on benthic communities. In this paper, a new biotic index, namely ALEX, is proposed to address the objectives of the Water Framework Directive and was tested in Mersin Bay (Levantine Sea, Turkey). Species were divided into four biogeographic groups, namely native species, casual species, established species and invasive species, and the metric considers the relative importance of these groups in samples. The index classified the ecological status of some stations which are shallow, and close to harbor and river mouths as bad or poor in February and October. The ALEX values were positively and significantly correlated with total nitrogen, silicate and silt percentage in sediment, and negatively correlated with depth and the distance from the harbor.

    2015-11-01

    A new spectral index—erosion resistance index (ERI)—was developed to assess erosion risks in desert landscapes. The index was developed by applying trigonometry to the combination of the green/red band-ratio and the red/near infrared band-ratio from very high spatial resolution imagery. The resultant ERI maps showed spatially cohesive distributions of high and low index values across the study areas. High index values were observed over areas that were resistant to erosion (such as desert pavement and dense vegetation), while low index values overlapped with areas likely dominated by loose sandy soils, such as stream beds and access roads. Although further investigation is warranted, this new index, ERI, shows promise for the assessment of erosion risks in desert regions.

    Full Text Available Ultrasonography is a useful procedure in evaluation of spleen size in different clinical conditions. In this study, we used it to evaluate spleen size in patients with various heptologic, hematologic and autoimmune diseases. To express spleen size, a spleen index (SI, the product of the transverse diameter and its perpendiculr diameter measured on the maximum-sectional image of the spleen, was used. Splenomegaly was present in high percentages of patients with liver, blood, collagen or autoimmune diseases, even though a majority of these spleens were not large enough to palpate. By grading the SI, characteristic distributions of SI were obtained for patients with different types of diseases. Obtaining and grading the SI by the use of ultrasound appears to be a significant supplemental aid for evaluating spleen size, especially in patients whose spleen are not palpable.

It was almost 50% before the introduction of antiretroviral therapy in the last decade, and was still at 28% in 2008, despite expanding access to antiretroviral therapy. Reviewing the causes of death may lead to further understanding of the timeline and natural history of TB-HIV coinfection, and in so doing help to devise an effective prevention strategy in Chiang Rai. In this study, we aimed to investigate the distribution of confirmed causes of death in patients coinfected with TB and HIV in Chiang Rai, describe the causes of such deaths along the timeline of TB treatment, and identify predictors of each cause of death.Methods: In this retrospective study, we reviewed the causes of death for 331 patients who died of TB-HIV coinfection at Chiang Rai Prachanukroh Hospital from 2005 to 2008. Causes of death were confirmed by reviewing medical records, vital registration, and the TB register in the province, as well as obtaining reconfirmation by two experienced HIV physicians.Results: The confirmed causes of death were TB (39%, acquired immune deficiency syndrome (AIDS-related opportunistic infections other than TB (AOI (29%, and other systemic diseases which were neither TB nor AIDS-related opportunistic infections (nonTB-nonAOI (16%. The definitive cause could not be confirmed in the remaining 16% of deaths. After starting the TB

  18. Droughts in a warming climate: A global assessment of Standardized precipitation index (SPI) and Reconnaissance drought index (RDI)

    2015-07-01

    Both drought and aridity indicate imbalance in water availability. While drought is a natural temporal hazard, aridity is a constant climatic feature. This paper investigates the changes in drought characteristics across different aridity zones with and without consideration of potential evapotranspiration (PET), as a means to better assess drought in a warming climate. Two drought indexes are employed: (1) Standardized precipitation index (SPI), which is solely based on precipitation; and (2) Reconnaissance drought index (RDI), which, in addition to precipitation, takes PET into account. The two indexes are first employed to observed precipitation and PET data for the period 1960-2009 from the CRU (Climate Research Unit, University of East Anglia) TS 3.1 database. The results indicate that although all the aridity zones experience both downward and upward drought trends, no significant trend is found over large parts of the zones. However, the agreement between SPI and RDI reduces from the hyper-arid zone on one extreme toward the humid zone on the other. In the three more humid zones (i.e. semi-arid, sub-humid, and humid), the indexes exhibit different trends, with RDI showing more decreasing trends (i.e. becoming drier). While SPI generally shows more drought prone areas than RDI for the pre-1998 period, the opposite is observed for the post-1998 period. Given the known changes to PET in observed records, and also expected increases as global warming intensifies, these results suggest that RDI will be consistently different to the SPI as global warming intensifies. This hypothesis is further tested for historic and future climate projections from the CSIRO (Commonwealth Scientific and Industrial Research Organisation, Australia) Mk3.6 global climate model (GCM), with use of the fifth phase of the Coupled Model Intercomparison Project (CMIP5) and RCP8.5 (Representative Concentration Pathways). In this case, PET is calculated using FAO56-PM model for assessment of

    1996-01-01

    Indoor climate was assessed in an apartment in Isehara City, Kanagawa Prefecture, Japan, by use of a fungal index. The index represents the environmental (climate) capacity to allow fungal growth; it is determined by measuring the growth rate of a biosensor fungus, Eurotium herbariorum J-183. Differences in climate among various parts of the apartment (microclimate) and its changes could be clarified by using the index. The index in the entire apartment was high in summer, low in winter, and intermediate in spring and autumn. According to the part of the apartment, the index was high in water-associated areas and cool areas. This high fungal index in cool areas was caused by the air at the same absolute humidity showing an increase in the relative humidity with a decrease in temperature. Fungal contamination rapidly progressed in areas with a high fungal index in this apartment. A correlation was observed between the fungal index and fungal contamination. Therefore, areas susceptible to fungal contamination can be estimated by use of the fungal index. PMID:8975622

    Electronic medical records (EMRs) has been expected to decrease health professional workload. The NASA Task Load Index has become an important tool for assessing workload in many domains. However, its application in assessing the impact of an EMR on nurse's workload has remained to be explored. In this paper we report the results of a study of workload and we explore the utility of applying the NASA Task Load Index to assess impact of an EMR at the end of its lifecycle on nurses' workload. It was found that mental and temporal demands were the most responsible for the workload. Further work along these lines is recommended.

    Potocki-Lupski syndrome (PTLS) is a genomic disorder associated with an ∼3 Mb duplication in 17p11.2. Clinical features include leanness, intellectual disability, autistic features and developmental deficits. RAI1 gene dosage is associated with the PTLS phenotypes. To understand where and when Rai1 overexpression is detrimental, we generated a mouse that over-expresses Rai1 conditionally in forebrain neurons (I-Rai1). Phenotypic characterization of I-Rai1 mice showed significant underweight, hyperactivity and impaired learning and memory ability compared with wild-type littermates. Doxycycline administration can turn off the transgene expression allowing the restoration of Rai1 normal expression levels. When the transgene was turned off from conception to 3 months of age, no phenotypic differences were observed between I-Rai1 and their wild-type littermates. Surprisingly, we found that turning off the transgene expression before the onset of the phenotypes (1-3 months) or after the onset of the phenotypes (3-5 months) cannot prevent nor reverse the phenotypic outcomes. Our results indicate that Rai1 dosage in forebrain neurons is critical during the development and is related to body weight regulation, activity levels and learning and memory.

    Seafood (fish and shellfish) is an excellent source of several essential nutrients for pregnant and lactating women. A short food frequency questionnaire (FFQ) that can be used to quantitatively estimate seafood consumption would be a valuable tool to assess seafood consumption in this group. Currently there is no such validated FFQ in Norway. The objective of this study was to establish and validate a seafood index from a seafood FFQ against blood biomarkers (the omega-3 index, the omega-3 HUFA score, and serum 25OH vitamin D). We assessed maternal seafood consumption during the 28th gestation week in healthy Norwegian women (n=54) with a seafood FFQ. A seafood index was developed to convert ordinal frequency data from the FFQ into numerical scale data. The following blood biomarkers were used as a validation method: omega-3 index, omega-3 HUFA score, and the serum 25OH vitamin D. The reported frequency of seafood as dinner and as spread was strongly correlated with the estimated frequencies of seafood as dinner and as spread. This indicated that the seafood index is a valuable tool to aggregate reported frequencies from the seafood FFQ. The seafood index composed of the frequency of seafood consumption and intake of omega-3 supplements, termed the total seafood index, correlated positively with the omega-3 index, omega-3 HUFA score, and 25OH vitamin D. We established and validated a seafood index from a seafood FFQ. The developed seafood index can be used when studying health effects of seafood consumption in large populations. This seafood FFQ captures seafood consumption and omega-3 supplement intake considerably well in a group of pregnant women.

    Paravalvular aortic regurgitation (AR) after transcatheter aortic valve replacement (TAVR) has been associated with increased mortality. Precise assessment of the degree of AR within the catheterization laboratory is crucial to take counter measures, but it remains challenging. The aim of this study was to determine whether any modification to AR index can improve its performance. The study included 64 patients treated with the Sapien valve (Edwards Life Sciences, Inc., Irvine, CA). The severity of AR was evaluated using echocardiography, angiography, and invasive hemodynamic parameters. We evaluated the time-integrated aortic regurgitation (TIAR) index as follows: (LV - Ao diastolic pressure time integral)/(LV systolic pressure time integral) × 100. We analyzed the AR index and TIAR index with the receiver operating characteristic (ROC) curve. AR was observed in 58 patients (90.7%) and graded as mild in 33 (51.6%), moderate in 20 (31.3%), or moderate to severe in 5 (7.8%) patients. No severe AR was detected. The AR index and TIAR index decreased proportionately to the increased severity of AR (P = 0.002 and P < 0.001, respectively). TIAR index < 80 was associated with a sensitivity of 86% and a specificity of 83% for ≥mild AR. The area under the curve was greater for the TIAR index compared to the AR index (0.93 vs. 0.74). The TIAR index provides a better hemodynamic measure for assessing severity of AR compared to the AR index. © 2015 Wiley Periodicals, Inc.

    Full Text Available At a time when anthropogenic activities are increasingly disturbing the overall ecological integrity of freshwater ecosystems, monitoring of biological communities is central to assessing the health and function of streams. This study aimed to use a large nation-wide database to develop a multimetric index (the Korean Benthic macroinvertebrate Index of Biological Integrity—KB-IBI applicable to the biological assessment of Korean streams. Reference and impaired conditions were determined based on watershed, chemical and physical criteria. Eight of an initial 34 candidate metrics were selected using a stepwise procedure that evaluated metric variability, redundancy, sensitivity and responsiveness to environmental gradients. The selected metrics were number of taxa, percent Ephemeroptera-Plecoptera-Trichoptera (EPT individuals, percent of a dominant taxon, percent taxa abundance without Chironomidae, Shannon’s diversity index, percent gatherer individuals, ratio of filterers and scrapers, and the Korean saprobic index. Our multimetric index successfully distinguished reference from impaired conditions. A scoring system was established for each core metric using its quartile range and response to anthropogenic disturbances. The multimetric index was classified by aggregating the individual metric ..scores and the value range was quadrisected to provide a narrative criterion (Poor, Fair, Good and Excellent to describe the biological integrity of the streams in the study. A validation procedure showed that the index is an effective method for evaluating stream conditions, and thus is appropriate for use in future studies measuring the long-term status of streams, and the effectiveness of restoration methods.

    2013-01-01

    This paper aims at contributing to the coastal environmental management by developing a new trophic status index of the water (TSIW). The index is tailored to semi-enclosed bays with estuarine characteristic like the Cienfuegos bay in Cuba. We also propose pressure indicators related to exporting and assimilation capacities as a tool to assess the vulnerability of the system to eutrophication. The TSIW is based on response indicators to eutrophication processes showing correspondence with the predefined pressure indicators and previous reports on water quality. Thus, the proposed trophic status index is a reliable scientific tool to measure the current stage of the water quality and to establish a baseline for further studies.

    The study was done to determine whether the new SCORE (Simple Calculated Osteoporosis Risk Estimation) index might reduce the utilization of bone mineral density (BMD) measurement. 989 consecutive patients who were referred by a range of physicians for BMD assessments at one of two clinics had a SCORE index constructed. Approximately 95% of the subjects were Caucasian. The index is based on only 6 factors: age, previous fractures, rheumatoid arthritis, estrogen use, weight, and race. All but 1 (0.1%) of those with a femoral neck BMD T-score of -2.5. One percent false negatives were also seen in the lumbar spine. The SCORE index correctly predicted those individuals who did not have an osteoporotic T-score. It was of the most value in the assessment and management of individuals possibly at risk for osteoporosis remains controversial. Our results suggest that the prior use of the SCORE index by the referring physicians to screen the patients sent for BMD measurement would have allowed them to exclude over 20% of the patients referred for assessment, and therefore reduce the need and cost of BMD measurement. The proportion of individuals who had a normal SCORE index, and would have been screened out, was 43% in the under 60 year age group, but in the 65 and over age group it provided no additional information to help with, for example, the National Osteoporosis Foundation (NOF) guidelines.

    Diabetes around the globe results in one major limb amputation every 30 seconds, over 2500 limbs lost per day. The underlying pathophysiology sometimes leads to a chronic inflammatory stage, which may prevent appropriate healing, and therefore, the need for a clear strategy for assessing and classifying wounds and wound healing cannot be overstated. Temperature is a surrogate marker for inflammation. Quantitative thermography using a numerical index provides a useful way to assess wound healing. Advances in technology have afforded the availability of low-cost, high-resolution thermal imaging systems, which can be used to quantify sensitive changes on the skin surface and may be particularly useful to develop monitoring strategies for wounds. This article provides a standardized technique for calculating a thermal index (TI) supported with a case report from assessment of a diabetic foot ulcer. In this single case study, the TI/wound inflammatory index indicates a shift from negative to positive (p Diabetes Technology Society.

    This paper examines the relationship between orthodontists' subjective assessment of treatment need and objective measurements obtained during standardized intra- and extraoral examinations. Logistic regression modeling was used to develop predictive models of treatment need. Data were obtained from 1155 eighth-grade students by four orthodontists who used standardized examination forms to assess demographics, trauma, skeletal relationships, morphologic malocclusion traits, and mandibular function. At the conclusion of the examination, the orthodontist rated the subjective treatment need as none, elective, recommended, soon, or immediate. For some analyses, the categories were collapsed to represent no need and need. The peer assessment rating (PAR) index (American validated version) was computed from the clinical exam findings and scoring of dental models; PAR scores were used to document malocclusion severity and treatment difficulty. Spearman rank correlation coefficients quantified the relationship between PAR scores and need categories. Logistic regression analysis modeled treatment need using components of the PAR index as well as other variables. The components of these models, as well as sensitivity and specificity, were compared with malocclusion severity/treatment difficulty scores obtained from malocclusion assessments using the PAR index. The five subjective treatment need categories and the PAR index scores were significantly correlated (rho = 0.62, porthodontists' subjective assessment of treatment need when that assessment is made in the absence of financial considerations and patient desires.

    Background: The Absorb™ BVS is a bioresorbable, everolimus-eluting scaffold approved and marketed for coronary use. Published data on long-term results after treatment are limited to a small number of patients, most of them with elective PCI of simple lesions. The importance of scaffold resorption is variably appreciated among cardiologists, and indications for use from health technology assessment bodies or guidelines are missing. Instruments are needed to collect, share and assess the experience being accumulated with this new device in several centres. Methods/Design: The BVS-RAI Registry is a spontaneous initiative of a group of Italian interventional cardiologists in cooperation with Centro di Ricerche Farmacologiche e Biomediche 'Mario Negri' Institute, and is not recipient of funding or benefits originating from the BVS manufacturer. It is a prospective registry with 5-year follow-up of all consecutive patients who have undergone successful implantation of 1 or more coronary BVS following the indications, techniques and protocols used in each of the participating institutions. Outcome measures are BVS target lesion failure within one year and device-oriented major adverse cardiac events within 5 years. The registry started in October 2012 and will extend enrolment throughout 2015, with the aim to include about 1000 patients. ClinicalTrials.gov identifier is CT02298413. Conclusions: The BVS-RAI Registry will contribute observational knowledge on the long-term safety and efficacy of the Absorb™ BVS as used in a number of Italian interventional centres in a broad spectrum of settings. Unrewarded and undirected consecutive patient enrolments are key-features of this observation, which is therefore likely to reflect common clinical practice in those centres. - Highlights: • prospective data collection of successful Absorb implantation; • expert Italian centers; • no restrictions for enrollment/no exclusion criteria; • clinical follow up;

    This study was an analysis of the correlation between pulmonary embolism (PE) and patient survival. Among 694 consecutive patients referred to our institution with clinical suspicion of acute PE who underwent CT pulmonary angiography, 188 patients comprised the study group: 87 women (46.3%, median age: 60.7; age range: 19-88 years) and 101 men (53.7%, median age: 66.9; age range: 21-97 years). PE was assessed by two radiologist who were blinded to the results from the follow-up. A PE index was derived for each set of images on the basis of the embolus size and location. Results were analyzed using logistic regression, and correlation with risk factors and patient outcome (survival or death) was calculated. We observed no significant correlation between the CTPE index and patient outcome (p = 0.703). The test of logistic regression with the sum of heart and liver disease or presence of cancer was significantly (p< 0.05) correlated with PE and overall patient outcome. Interobserver agreement showed a significant correlation rate for the assessment of the PE index (0.993; p< 0.001). In our study the CT PE index did not translate into patient outcome. Prospective larger scale studies are needed to confirm the predictive value of the index and refine the index criteria. (orig.)

    Groundwater pollution due to anthropogenic activities is one of the major environmental problems in urban and industrial areas. The aim of this work is to propose a new integrated methodology to assess actual and forecasted groundwater vulnerability by combining Drastic and susceptibility index. The contamination susceptibility index (SI) at a given location was calculated by taking the product of the vulnerability DRASTIC index (VI) and the quality index (QI): SI=VI x QI. The superficial aquifer of Annaba plain was the study case proposed for the application of this methodology. The study revealed that the area with Very High vulnerability would increase 73 % in this superficial layer. This result can be explained by the susceptibility index map shows both hydrogeological and hydrochemical data related to the contamination problem including areas that should be taken into consideration during water management planning. The index map indicates that the most susceptible groundwater is occupies the majority of the study area. The validity of the DRASTIC and the susceptibility index methods, verified by comparing the distribution of some pollutants (Daouad, 2013) in the groundwater and the different vulnerability classes, shows a high contamination that affect the water quality in study areas.

    Full Text Available Este articulo está centrado en el género musical conocido como el rai, considerado entre los más representativos de la música popular argelina y cuya transmisión fue posible gracias a la labor de divulgación realizada por los seij/seijas1 y el mensaje de compromiso con los cambios sociales, religiosos y culturales inmersos en los textos de las composiciones. No obstante, el carácter marginal que sufrió el rai durante décadas, unido a su difusión en Europa mediante los procesos migratorios y la posterior globalización, han contribuido a la incursión del género dentro de las músicas urbanas y a ser conocido, a nivel internacional, bajo la etiqueta de World Music. La popularidad de la que goza actualmente el rai al sintetizar y aunar diferentes tradiciones, lenguas, géneros poéticos e instrumentos tradicionales y occidentales, en general electrónicos, así como su divulgación en los medios de comunicación y la comercialización en la industria discográfica, no impide, sin embargo, que la esencia del rai siga vigente, así como su reivindicación y compromiso social con los más desfavorecidos.

    Full Text Available Abstract Background Smith-Magenis syndrome (SMS is a developmental disability/multiple congenital anomaly disorder resulting from haploinsufficiency of RAI1. It is characterized by distinctive facial features, brachydactyly, sleep disturbances, and stereotypic behaviors. Methods We investigated a cohort of 15 individuals with a clinical suspicion of SMS who showed neither deletion in the SMS critical region nor damaging variants in RAI1 using whole exome sequencing. A combination of network analysis (co-expression and biomedical text mining, transcriptomics, and circularized chromatin conformation capture (4C-seq was applied to verify whether modified genes are part of the same disease network as known SMS-causing genes. Results Potentially deleterious variants were identified in nine of these individuals using whole-exome sequencing. Eight of these changes affect KMT2D, ZEB2, MAP2K2, GLDC, CASK, MECP2, KDM5C, and POGZ, known to be associated with Kabuki syndrome 1, Mowat-Wilson syndrome, cardiofaciocutaneous syndrome, glycine encephalopathy, mental retardation and microcephaly with pontine and cerebellar hypoplasia, X-linked mental retardation 13, X-linked mental retardation Claes-Jensen type, and White-Sutton syndrome, respectively. The ninth individual carries a de novo variant in JAKMIP1, a regulator of neuronal translation that was recently found deleted in a patient with autism spectrum disorder. Analyses of co-expression and biomedical text mining suggest that these pathologies and SMS are part of the same disease network. Further support for this hypothesis was obtained from transcriptome profiling that showed that the expression levels of both Zeb2 and Map2k2 are perturbed in Rai1 –/– mice. As an orthogonal approach to potentially contributory disease gene variants, we used chromatin conformation capture to reveal chromatin contacts between RAI1 and the loci flanking ZEB2 and GLDC, as well as between RAI1 and human orthologs of the

    Full Text Available In most countries, crash statistics have becoming very crucial in evaluating road’s safety level. In Malaysia, these data are very important in deciding crash-prone areas known as black spot where specific road improvements plan will be proposed. However due to the unavailability of reliable crash data in many developing countries, appropriate road maintenance measures are facing great troubles. In light of that, several proactive methods in defining road’s safety level such as Road Assessment Program (RAP have emerged. This research aim to compare two proactive methods that have been tested in Malaysian roads ; road assessment program and road environment risk index which was developed based on composite index theory in defining road’s safety level. Composite road environment risk index was combining several crucial environment indicators, assigning weight and aggregating the individual index together to form a single value representing the road’s safety level. Based on the results, it can be concluded that both road assessment program and composite road environment risk index are contradicted in six different ways such as type of speed used, type of analysis used and their final outcomes. However, with an aim to promote safer roads, these two methods can be used concurrently as the outcomes in both methods seems to fulfil each other’s gap very well.

    Objective To investigate whether the h index (a bibliometric tool which is increasingly used to assess and appraise an individual's research performance) could be improved to better measure the academic performance and citation profile for individual healthcare researchers. Design Cohort study. Setting Faculty of Medicine, Imperial College London, UK. Participants Publication lists from 1 January 2000 until 31 December 2009 for 501 academic healthcare researchers from the Faculty of Medicine. Main outcome measures The h index for each researcher was calculated over a nine-year period. The citation count for each researcher was differentiated into high (h2 upper), core (h2 centre) and low (h2 lower) visibility areas. Segmented regression model (sRM) was used to statistically estimate number of high visibility publications (sRM value). Validity of the h index and other proposed adjuncts were analysed against academic rank and conventional bibliometric indicators. Results Construct validity was demonstrated for h index, h2 upper, h2 centre, h2 lower and sRM value (all P < 0.05). Convergent validity of the h index and sRM value was shown by significant correlations with total number of publications (r = 0.89 and 0.86 respectively, P < 0.05) and total number of citations (r = 0.96 and 0.65, respectively, P < 0.05). Significant differences in h index and sRM value existed between non-physician and physician researchers (P < 0.05). Conclusions This study supports the construct validity of the h index as a measure of healthcare researcher academic rank. It also identifies the assessment value of our developed indices of h2 upper, h2 centre, h2 lower and sRM. These can be applied in combination with the h index to provide additional objective evidence to appraise the performance and impact of an academic healthcare researcher. PMID:23358276

    Full Text Available Background: Use of the Tei index has not been described to assess myocardial function before or after surgery in pediatric patients. This study was designed to evaluate the left ventricular (LV function using the Tei index pre- and post-cardiopulmonary bypass in patients with lesion that result in a volume loaded right ventricle (RV. Methods: Retrospective data on 55 patients who underwent repair of a cardiac defect were analyzed. Patients with volume overload RV (n = 15 were compared to patients without volume overload but with other cardiac defects (n = 40. We reviewed pre- and post-operative LV myocardial performance index (Tei index. Tei index was obtained from transesophageal Doppler echocardiogram. Results: Patients with right heart volume overload, the mean preoperative Tei index was 0.6, with a postoperative mean decrease of 0.207 (P = 0.014. Patients without right heart volume overload, the mean preoperative Tei was 0.48 with no significant postoperative change (P = 0.82. Conclusion: Pre- and post-operative transesophageal echocardiogram assessment provides an easy and quick way of evaluating LV function intra-operatively using LV Tei index. Preoperative LV Tei index was greater in the RV volume overload defects indicating diminished LV global function. This normalized in the immediate postoperative period, implying an immediate improvement in LV function. In patients without right heart volume load, consist of other cardiac defects, demonstrated no changes in the pre- and post-operative LV Tei. This implies that LV function was similar after the surgery.

    The ever increasing level of air pollution in most areas of the world has led to development of a variety of air quality indices for estimation of health effects of air pollution, though the indices have their own limitations such as high levels of subjectivity. Present study, therefore, aimed at developing a novel, fuzzy-based air quality index (FAQI ) to handle such limitations. The index developed by present study is based on fuzzy logic that is considered as one of the most common computational methods of artificial intelligence. In addition to criteria air pollutants (i.e. CO, SO 2, PM 10, O 3, NO 2), benzene, toluene, ethylbenzene, xylene, and 1,3-butadiene were also taken into account in the index proposed, because of their considerable health effects. Different weighting factors were then assigned to each pollutant according to its priority. Trapezoidal membership functions were employed for classifications and the final index consisted of 72 inference rules. To assess the performance of the index, a case study was carried out employing air quality data at five different sampling stations in Tehran, Iran, from January 2008 to December 2009, results of which were then compared to the results obtained from USEPA air quality index (AQI). According to the results from present study, fuzzy-based air quality index is a comprehensive tool for classification of air quality and tends to produce accurate results. Therefore, it can be considered useful, reliable, and suitable for consideration by local authorities in air quality assessment and management schemes. Fuzzy-based air quality index (FAQI).

    The case fatality rate in patients with tuberculosis (TB) associated with human immunodeficiency virus (HIV) has been particularly high in Chiang Rai, Northern Thailand. It was almost 50% before the introduction of antiretroviral therapy in the last decade, and was still at 28% in 2008, despite expanding access to antiretroviral therapy. Reviewing the causes of death may lead to further understanding of the timeline and natural history of TB-HIV coinfection, and in so doing help to devise an effective prevention strategy in Chiang Rai. In this study, we aimed to investigate the distribution of confirmed causes of death in patients coinfected with TB and HIV in Chiang Rai, describe the causes of such deaths along the timeline of TB treatment, and identify predictors of each cause of death. In this retrospective study, we reviewed the causes of death for 331 patients who died of TB-HIV coinfection at Chiang Rai Prachanukroh Hospital from 2005 to 2008. Causes of death were confirmed by reviewing medical records, vital registration, and the TB register in the province, as well as obtaining reconfirmation by two experienced HIV physicians. The confirmed causes of death were TB (39%), acquired immune deficiency syndrome (AIDS)-related opportunistic infections other than TB (AOI) (29%), and other systemic diseases which were neither TB nor AIDS-related opportunistic infections (nonTB-nonAOI) (16%). The definitive cause could not be confirmed in the remaining 16% of deaths. After starting the TB treatment, deaths caused by TB occurred earlier compared with deaths caused by AOI, which occurred steadily throughout the course of TB treatment, whilst deaths caused by non-TB-nonAOI increased gradually in later months. Further analysis by multivariate multinomial regression analysis showed that deaths in the first month (adjusted odds ratio [aOR] 4.64, 95% confidence interval [CI] 2.49-8.63), CD4 count ≥ 200 cells/mm(3) (aOR 5.33, CI 1.05-26.10), non-category 1 TB treatment

    Osteoporosis may complicate surgical fixation and healing of proximal humerus fractures and should be assessed preoperatively. Peripheral quantitative CT (pQCT) and the Tingart measurement are helpful methods, but both have limitations in clinical use because of limited availability (pQCT) or fracture lines crossing the area of interest (Tingart measurement). The aim of our study was to introduce and validate a simple cortical index to assess the quality of bone in proximal humerus fractures using AP radiographs. We asked: (1) How do the deltoid tuberosity index and Tingart measurement correlate with each other, with patient age, and local bone mineral density (BMD) of the humeral head, measured by pQCT? (2) Which threshold values for the deltoid tuberosity index and Tingart measurement optimally discriminate poor local bone quality of the proximal humerus? (3) Are the deltoid tuberosity index and Tingart measurement clinically applicable and reproducible in patients with proximal humerus fractures? The deltoid tuberosity index was measured immediately above the upper end of the deltoid tuberosity. At this position, where the outer cortical borders become parallel, the deltoid tuberosity index equals the ratio between the outer cortical and inner endosteal diameter. In the first part of our study, we retrospectively measured the deltoid tuberosity index on 31 patients (16 women, 15 men; mean age, 65 years; range, 22-83 years) who were scheduled for elective surgery other than fracture repair. Inclusion criteria were available native pQCT scans, AP shoulder radiographs taken in internal rotation, and no previous shoulder surgery. The deltoid tuberosity index and the Tingart measurement were measured on the preoperative internal rotation AP radiograph. The second part of our study was performed by reviewing 40 radiographs of patients with proximal humerus fractures (31 women, nine men; median age, 65 years; range, 22-88 years).

    Full Text Available Currently, different methods are used for spatial assessment of environmental conditions of the territory. The most informative are geochemical methods, which involve conducting field research with the selection and analysis of samples. Typically, the analytical data are used in the calculations of environmental indexes, ratios, integral indicators, etc. The authors believe that disadvantage of these methods is ignoring the landscape features of the territory, which does not allow to objectively assess it. The article substantiates the introduction of the landscape-ecological index (LEI to assess the environmental status of any territory. LEI calculation methodology includes a solid geochemical survey of the territory with sampling of all components of the environment (soil, vegetation, water. LEI calculation is carried out by the ratio of laboratory analysis samples results from standard rates for each sample at each point of selection and an integral factor of the landscape sensitivity in which each experimental area is located. Integral sensitivity rate of the landscape is calculated on the basis of the sensitivity assessment matrix developed by the authors. The authors foresee matrix filling based on expert assessments of the landscape sensitivity from 0 to 1, where 0 is the lowest sensitivity, and 1 - the highest. Testing methods were implemented on the example of Pechenigy reservoir basin within Kharkiv region. Based on the field experiment two indicators have been designed: a comprehensive environmental index (KEI J.V. Gryb method, and landscape-ecological index (LEI, the author’s (N.V. Maksymenko method. The obtained results formed the basis for mapping two models that reflect KEI and LEI spatial distribution. Comparative evaluation of the two models shows that it is the landscape-ecological index that allows a realistic assessment of the environmental condition and the environmental problems of the area.

    This study aimed to develop an index that can rank welding workplace that associate well with possible health risk of welders. Welding Fumes Health Index (WFHI) were developed based on data from case studies conducted in Plant 1 and Plant 2. Personal sampling of welding fumes to assess the concentration of metal constituents along with series of lung function tests was conducted. Fifteen metal constituents were investigated in each case study. Index values were derived from aggregation analysis of metal constituent concentration while significant lung functions were recognized through statistical analysis in each plant. The results showed none of the metal constituent concentration was exceeding the permissible exposure limit (PEL) for all plants. However, statistical analysis showed significant mean differences of lung functions between welders and non-welders. The index was then applied to one of the welding industry (Plant 3) for verification purpose. The developed index showed its promising ability to rank welding workplace, according to the multiple constituent concentrations of welding fumes that associates well with lung functions of the investigated welders. There was possibility that some of the metal constituents were below the detection limit leading to '0' value of sub index, thus the multiplicative form of aggregation model was not suitable for analysis. On the other hand, maximum or minimum operator forms suffer from compensation issues and were not considered in this study.

    The psychometric properties of instruments used to measure self-reported experiences of discrimination in epidemiologic studies are rarely assessed, especially regarding construct validity. The authors used 2000–2001 data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study to examine differential item functioning (DIF) in 2 versions of the Experiences of Discrimination (EOD) Index, an index measuring self-reported experiences of racial/ethnic and gender discrimination. DIF may confound interpretation of subgroup differences. Large DIF was observed for 2 of 7 racial/ethnic discrimination items: White participants reported more racial/ethnic discrimination for the “at school” item, and black participants reported more racial/ethnic discrimination for the “getting housing” item. The large DIF by race/ethnicity in the index for racial/ethnic discrimination probably reflects item impact and is the result of valid group differences between blacks and whites regarding their respective experiences of discrimination. The authors also observed large DIF by race/ethnicity for 3 of 7 gender discrimination items. This is more likely to have been due to item bias. Users of the EOD Index must consider the advantages and disadvantages of DIF adjustment (omitting items, constructing separate measures, and retaining items). The EOD Index has substantial usefulness as an instrument that can assess self-reported experiences of discrimination. PMID:22038104

  9. Assessment of Silt Density Index (SDI) as Fouling Propensity Parameter in Reverse Osmosis Desalination

    2011-07-01

    Reverse osmosis operations are facing persistent fouling phenomenon that has challenged the integrity of these processes. Prediction of fouling potential by measuring a fouling index toward feed water is essential to ensure robust operation. Moreover, employing a reliable fouling index with good reproducibility and precision is necessary. Silt density index (SDI) is considered insufficient in terms of reliability and empirical theory, among other limitations. Nevertheless due its simplicity, SDI measurement is utilized extensively in RO desalination systems. The aim of this research is to assess the reliability of SDI. Methods include the investigation of different SDI membranes and study of the nature of the SDI filtration. Results demonstrate the existence of the membrane properties\\' variation within manufacturers, which then causes a lack of accuracy in fouling risk estimation. The nature of particles during SDI filtration provides information that particle concentration and size play a significant role on SDI quantification with substantial representation given by particles with size close to membrane nominal pore size. Moreover, turbidity assisted SDI measurements along with determination of UF pretreated and clean water fouling potential, establishes the indication of non-fouling related phenomena involved on SDI measurement such as a natural organic matter adsorption and hydrodynamic condition that alters during filtration. Additionally, it was found that the latter affects the sensitivity of SDI by being represented by some portions of SDI value. Keywords: Reverse Osmosis, Fouling index, Particulate Fouling, Silt Density Index (SDI), and Assessment of SDI.

  10. Using the H Index to Assess Impact of DOE National Laboratories

    Energy Technology Data Exchange (ETDEWEB)

    Springer, Everett P. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2016-05-13

    The most readily accessible elements of the Emerald Matrix by quantitative measures are the knowledge and economy related measures. In this paper, the H Index for an institution will be used to assess STE impact, which is in the knowledge generation element. The H Index was developed by Hirsch (2005) as a measure of an individual’s scientific impact. The H Index is defined as the number of publications that have been cited h or more times for a given author. It has been generalized to organizations. Doing so leads to a complication in that H index scales with the number of publications. Although this may not be problematic when comparing individual researchers, it systematically favors larger institutions. Molinari and Molinari (2008) proposed an alternative index (hm) designed to assess organizational impact. It transforms the H Index for an organization into an impact index by removing a factor dependent on the number of publications. The hm provides another approach to compare institutions provided that differences in the citation patterns associated with fields of study are addressed. Kinney (2007) used the Molinari and Molinari (2008) approach to compare various scientific institutions in nonbiomedical research areas. Kinney (2007) used the Thomson Reuters Web of Science (WoS) as the source and used publications in nonbiomedical research areas, which is very important because the research areas of universities are much broader than say a DOE national laboratory. Also there are differences in citation rates for the various research fields that make comparisons between individuals or organizations difficult. The results from Kinney (2007) are given in Table 1 and indicate that the DOE national laboratories compare favorably with the selected universities in terms of impact (hm) in the research areas used in Kinney’s analysis. This report will compare hm for DOE national laboratories using an approach similar to Kinney (2007) providing a measure of impact of

    To assess a newly developed index to measure interproximal stain and evaluate the stain removal efficacy of two commercially available manual toothbrushes. This was a randomized, examiner-blind, parallel-group, two-treatment clinical trial of two weeks' duration. Subjects qualified for the study if they had an average Modified Lobene Stain Index of ≥ 1.5 from two anterior teeth. At baseline, subjects brushed in front of a mirror for one minute under supervision. All subjects were provided with a standard 0.243% sodium fluoride dentifrice and were randomly assigned either an Oral-B Pulsar manual brush (OBP) or a Colgate Whitening manual brush (CW) to use for two weeks. Stain was reassessed after two weeks of product use. Stain measurements were conducted using the Modified Lobene Stain Index and the new Interproximal Modified Lobene Stain Index, which allows for assessment of stain in hard-to-reach areas using the same area and intensity scales as the Modified Lobene Stain Index. Use of the two manual brushes resulted in statistically significant reductions in surface stain relative to baseline after two weeks of use. Median stain reductions were 78% and 60% for the OBP and CW, respectively, as measured by the Modified Lobene Stain Index. The mean changes in the composite scores from baseline to week two were 1.85 and 1.57 for the two treatment groups, respectively. Statistically significant reductions from baseline were also found for the intensity and extent of stain measures (p brush and 83% reduction with the CW brush. For the gingival sites, the median stain removal percentages were 83% and 50%, respectively For the body region, a median stain removal of 100% was found for both treatment groups. No statistically significant differences were found between the two groups for the mean composite scores for either index. Both manual brushes showed effective stain removal, including interproximal hard-to-reach sites. The Interproximal Modified Lobene Stain Index

  12. Assessment of condition in pejerrey Odontesthes bonariensis (Atheriniformes: Atherinopsidae populations: which index works best?

    Directory of Open Access Journals (Sweden)

    Claudio R. M. Baigún

    Full Text Available The pejerrey Odontesthes bonariensis is the most important target species in temperate freshwater fisheries of Argentina, and assessment of condition has been a regular practice and common diagnostic tool. Most pejerrey fishery studies have used Fulton's (K index, without testing whether underlying assumptions or requirements were met. We analyzed and contrasted the applicability of K, Kn and Wr indices to assess condition status in several pejerrey populations inhabiting Pampean lakes. Our results showed that whereas Wr and Kn displayed significant condition changes across length at some study lakes, Kn portrayed a small range of variation. We also noted that pejerrey maximum length and size structure strongly varied among populations probably due to the characteristics of trophic niche changes through lifespan, depending on lake limnological characteristics and zooplankton availability. We conclude that the K index should be disregarded in those cases where populations show allometric growth and size ranges strongly vary. In turn, the Kn index appears to be only appropriate for regular within population assessment, being difficult to apply when comparisons between populations are needed and when they exhibit different weight-length relationship slopes. Finally, the Wr index should be strongly preferred if the objective is to perform comparisons between pejerrey populations, particularly when population structure is not well known, stocking has been used for population recovery, lakes are strongly supported by limnological changes, data are limited to only one or few samplings and metaphoetesis is suspected in pejerrey populations.

    To determine the diagnostic accuracy of modified CT severity index in assessing the severe acute pancreatitis keeping APACHE II as gold standard. Cross-sectional (validation) study. Department of Radiology, Allied Hospital, Faisalabad, from February to August 2014. A total of 120 patients of either gender aged 20-60 years with epigastric pain radiating to back and having sonographic findings (decreased or heterogeneous pancreatic echogenicity, pancreatic enlargement, peripancreatic fluid collection), supportive of acute pancreatitis were taken. CT with intravenous contrast was performed on 128-slice scanner within 24 hours of presentation. Slice thickness was 3 mm in region of pancreas. Modified CT severity index was calculated. Score above 5 was graded as severe pancreatitis. APACHE II score of >11 considered as gold standard was also calculated within 24 hours of admission. Mean age of the patients was 39.03 ±8.71 years. Most of the patients were females 73 (60.8%). Out of 120 patients, 43 (35.83%) patients had severe acute pancreatitis. Sensitivity, specificity, positive predictive value and negative predictive value of modified CT severity index in assessing the severe acute pancreatitis were 100%, 87%, 81.13% and 100%, respectively. The diagnostic accuracy was yielded as 91.67% considered APACHE II as gold standard. Modified CT severity index had high diagnostic accuracy in assessment of severe acute pancreatitis and can be used reliably in early prediction of complications of severe acute pancreatitis.

    Full Text Available Objective: The object of this research is public innovation support in European Economic Area and its effectiveness assessment. The main aim is to propose a new model for public innovation support effectiveness assessment, adjusted to contemporary needs and based on practice of public innovation support development. Research Design & Methods: The methods of comparative, cluster, regression, modelling analysis, multi-criteria evaluation, analogy search, logical abstraction and impact evaluation have been applied for the research presented in this paper. Findings:  The paper conceptualizes a new model for the assessment of public innovation support. It is based on theoretical argumentation and practical verification. Its structure is based on new solutions and quantitative assessment methods. Implications & Recommendations: The analysis of the proposed model applicability revealed important patterns for the public innovation support impact assessment. Findings suggest that the increase of public innovation support index is a necessary but insufficient condition for the growth of the countries innovation index. The impact of public innovation support occurs only in the long run, as the delay of the effect exists. Contribution & Value Added: The proposed system of quantitative and qualitative indicators that characterize any public innovation support system (public innovation support index enables the creation and implementation of measures devoted to the public innovation support impact improvement at EU and national level. The practical application of the suggested model is significant for the effectiveness improvement of public innovation support at EU institutions.

    This paper offers a potential measurement solution for assessing disaster impacts and subsequent recovery at the household level by using a modified domestic assets index (MDAI) approach. Assessment of the utility of the domestic assets index first proposed by Bates, Killian and Peacock (1984) has been confined to earthquake areas in the Americas and southern Europe. This paper modifies and extends the approach to the Indian sub-continent and to coastal surge hazards utilizing data collected from 1,000 households impacted by the Indian Ocean tsunami (2004) in the Nagapattinam district of south-eastern India. The analyses suggest that the MDAI scale is a reliable and valid measure of household living conditions and is useful in assessing disaster impacts and tracking recovery efforts over time. It can facilitate longitudinal studies, encourage cross-cultural, cross-national comparisons of disaster impacts and inform national and international donors of the itemized monetary losses from disasters at the household level.

    Biotic indices for monitoring marine ecosystems are mostly based on the analysis of benthic macroinvertebrate communities. Due to their high sensitivity to pollution and fast response to environmental changes, bacterial assemblages could complement the information provided by benthic metazoan communities as indicators of human-induced impacts, but so far, this biological component has not been well explored for this purpose. Here we performed 16S rRNA gene amplicon sequencing to analyze the bacterial assemblage composition of 51 estuarine and coastal stations characterized by different environmental conditions and human-derived pressures. Using the relative abundance of putative indicator bacterial taxa, we developed a biotic index that is significantly correlated with a sediment quality index calculated on the basis of organic and inorganic compound concentrations. This new index based on bacterial assemblage composition can be a sensitive tool for providing a fast environmental assessment and allow a more comprehensive integrative ecosystem approach for environmental management. © 2016.

    To assess the quantitative measurement of proteinuria by using random urine protein:creatinine index/ratio in comparison with 24 hours urinary protein excretion in patients of renal diseases having normal glomerular filtration rate. One hundred and thirty patients, 94 males and 36 females, with an age range of 5 to 60 years; having proteinuria of more than 150 mg/day were included in this study. Qualitative urinary protein estimation was done on random urine specimen by dipstick. Quantitative measurement of protein in the random and 24 hours urine specimens were carried out by a method based on the formation of a red complex of protein with pyrogallal red in acid medium on Micro lab 200 (Merck). Estimation of creatinine was done on Selectra -2 (Merck) by Jaffe's reaction. The urine protein:creatinine index and ratio were calculated by dividing the urine protein concentration (mg/L) by urine creatinine concentration (mmol/L) multilplied by 10 and mg/mg respectively. The protein:creatinine index and ratio of more than 140 and 0.18 respectively in a random urine sample indicated pathological proteinuria. An excellent correlation (r=0.96) was found between random urine protein:creatinine index/ratio and standard 24 hours urinary protein excretion in these patients (pprotein:creatinine index in random urine is a convenient, quick and reliable method of estimation of proteinuria as compared to 24 hours of urinary protein excretion for diagnosis and monitoring of renal diseases in our medical setup.

    Objectives: Facial Aesthetics, a major consideration in orthodontic diagnosis and treatment planning, may not be judged correctly and completely by simply analyzing dental occlusion or osseous structures. Despite this importance, there is no index to guarantee availability of treatment or prioritize patients based on their soft tissue treatment needs. Individuals having well-aligned teeth but unaesthetic convex profiles do not get included for treatment as per current malocclusion indices. The aim of this investigation is to develop an aesthetic index based on facial profiles which could be used as an additional tool with malocclusion indices. Materials and Methods: A chart showing typical facial profile changes due to underlying malocclusions was generated by soft tissue manipulations of standardized profile photographs of a well-balanced male and female face. A panel of 62 orthodontists judged the profile photographs of 100 patients with different soft tissue patterns for assessing profile variations and treatment need. The index was later tested in a cross-section of school population. Statistical analysis was done using “irr” package of R environment version 2.15.1. Results: The index exhibited very good reliability in determining profile variations (Fleiss kappa 0.866, P Aesthetic index, based on patient's soft tissue profile requirements is proposed, which can complement existing indices to ensure treatment to those in need.

    Many scholars have used microtremor applications to evaluate the vulnerability index. In order to reach fast and reliable results, microtremor measurement is preferred as it is a cost-effective method. In this paper, the vulnerability index will be reviewed by utilization of microtremor measurement results in Nicosia city. 100 measurement stations have been used to collect microtremor data and the data were analysed by using Nakamura's method. The value of vulnerability index (Kg) has been evaluated by using the fundamental frequency and amplification factor. The results obtained by the artificial neural network (ANN) will be compared with microtremor measurements. Vulnerability Index Assessment using Neural Networks (VIANN) is a backpropagation neural network, which uses the original input microtremor Horizontal Vertical Spectrum Ratio (HVSR) spectrum set. A 3-layer back propagation neural network which contains 4096 input, 28 hidden and 3 output neurons are used in this suggested system. The output neurons are classified according to acceleration sensitivity zone, velocity zones, or displacement zones. The sites are classified by their vulnerability index values using binary coding: [1 0 0] for the acceleration sensitive zone, [0 1 0] for the velocity sensitive zone, and [0 0 1] for the displacement sensitive zone.

    Assessment of DNA profile quality is vital in forensic DNA analysis, both in order to determine the evidentiary value of DNA results and to compare the performance of different DNA analysis protocols. Generally the quality assessment is performed through manual examination of the DNA profiles based on empirical knowledge, or by comparing the intensities (allelic peak heights) of the capillary electrophoresis electropherograms. We recently developed a ranking index for unbiased and quantitative quality assessment of forensic DNA profiles, the forensic DNA profile index (FI) (Hedman et al. Improved forensic DNA analysis through the use of alternative DNA polymerases and statistical modeling of DNA profiles, Biotechniques 47 (2009) 951-958). FI uses electropherogram data to combine the intensities of the allelic peaks with the balances within and between loci, using Principal Components Analysis. Here we present the construction of FI. We explain the mathematical and statistical methodologies used and present details about the applied data reduction method. Thereby we show how to adapt the ranking index for any Short Tandem Repeat-based forensic DNA typing system through validation against a manual grading scale and calibration against a specific set of DNA profiles. The developed tool provides unbiased quality assessment of forensic DNA profiles. It can be applied for any DNA profiling system based on Short Tandem Repeat markers. Apart from crime related DNA analysis, FI can therefore be used as a quality tool in paternal or familial testing as well as in disaster victim identification.

    To ensure optimal clinical performance of digital mammography, it is necessary to obtain images with high spatial resolution and low noise, keeping radiation exposure as low as possible. These requirements directly affect the interpretation of radiologists. The quality of a digital image should be assessed using objective measurements. In general, these methods measure the similarity between a degraded image and an ideal image without degradation (ground-truth), used as a reference. These methods are called Full-Reference Image Quality Assessment (FR-IQA). However, for digital mammography, an image without degradation is not available in clinical practice; thus, an objective method to assess the quality of mammograms must be performed without reference. The purpose of this study is to present a Normalized Anisotropic Quality Index (NAQI), based on the Rényi entropy in the pseudo-Wigner domain, to assess mammography images in terms of spatial resolution and noise without any reference. The method was validated using synthetic images acquired through an anthropomorphic breast software phantom, and the clinical exposures on anthropomorphic breast physical phantoms and patient's mammograms. The results reported by this noreference index follow the same behavior as other well-established full-reference metrics, e.g., the peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM). Reductions of 50% on the radiation dose in phantom images were translated as a decrease of 4dB on the PSNR, 25% on the SSIM and 33% on the NAQI, evidencing that the proposed metric is sensitive to the noise resulted from dose reduction. The clinical results showed that images reduced to 53% and 30% of the standard radiation dose reported reductions of 15% and 25% on the NAQI, respectively. Thus, this index may be used in clinical practice as an image quality indicator to improve the quality assurance programs in mammography; hence, the proposed method reduces the subjectivity

    Manual handling of disabled patients - as regards movement - is one of the major factors affecting acute low back pain of exposed nursing staff. In the absence of quantitative methods assessing this kind of risk, the Research Unit Ergonomics of Posture and Movement of Milan developed in 1997 a risk assessment method called Movement and Assistance of Hospital Patients (MAPO), which is applicable in hospital wards.A first study conducted in 1999 allowed the identification of three levels of MAPO index corresponding with increasing probabilities of being affected by acute low back pain. In accordance with the well-known traffic light model, for MAPO index values between 0 and 1.5 the risk is considered to be absent or negligible. For values between 1.51 and 5.00 the risk is considered to be moderate. For values exceeding 5.00 the risk is considered to be high. In view of the limitations of the previous study, the results needed confirmation and so, in 2000-2001, another cross-sectional study was carried out, which included 191 hospital wards for acute and chronic patients and 2603 exposed subjects. This paper presents the analytical results of the association between the MAPO index and acute low back pain in this new data sample. The agreement between results of the two studies indicates that the MAPO index can be used as a risk index, although with some caution, as detailed in the paper. It can assess the risk exposure level of patient manual handling in wards and can be a useful tool for planning effective preventive actions to reduce the risk of work-related musculoskeletal disorders in health-care workers looking after disabled patients.

    Full Text Available This study aims to develop a benthic macroinvertebrate multimetric index for assessing the ecological quality of streams in Northeastern Thailand. ANOSIM indicated that the benthic macroinvertebrate assemblage in both of each basin and each season were not significantly different (R = 0.09, p = 0.24 and R = 0.07, p = 0.35, respectively. The efficacy metrics of each basin consisting of the Mekong II, the Chi, and the Mun basins were integrated and calibrated. A total of 255 data sets of water physico-chemical and benthic macroinvertebrates during the dry period (cool and hot seasons were obtained. The stream classification could be divided into three groups: the reference group (48 stations, the stressed group (42 stations, and the intermediate group (165 stations. Twelve out of 56 metrics have been considered as a core metric for the development of a biological index for quality streams in the Northeast, including Total taxa, EPT taxa, Ephemeroptera taxa, Coleoptera taxa, % EPT, % Chironomidae, % Tolerant individuals, % Intolerant individuals, Beck's index, HBI, Predator taxa, and Clinger taxa. Moreover, this metric set covered the structure and function of organisms including the diversity of species, community structure, tolerance/intolerance measures, functional feeding group, and habit. From the efficacy validation of the biological index, the results of stream assessment corresponded to the classification sites with the physico-chemical characteristics.

    The Sustainable Development Goals (SDGs) -- agreed in 2015 by all 193 member states of the United Nations and complemented by commitments made in the Paris Agreement -- map out a broad spectrum of economic, social and environmental objectives to be achieved by 2030. Reaching these goals will require deep transformations in every country, as well as major efforts in monitoring and measuring progress. Here we introduce the SDG Index and Dashboards as analytical tools for assessing countries' baselines for the SDGs that can be applied by researchers in the cross-disciplinary analyses required for implementation. The Index and Dashboards synthesize available country-level data for all 17 goals, and for each country estimate the size of the gap towards achieving the SDGs. They will be updated annually. All 149 countries for which sufficient data is available face significant challenges in achieving the goals, and many countries' development strategies are imbalanced across the economic, social and environmental priorities. We illustrate the analytical value of the index by examining its relationship with other widely used development indices and by showing how it accounts for cross-national differences in subjective well-being. Given significant data gaps, scope and coverage of the Index and Dashboards are limited, but we suggest that these analyses represent a starting point for a comprehensive assessment of national SDG baselines and can help policymakers determine priorities for early action and monitor progress. The tools also identify data gaps that must be closed for SDG monitoring.

    In the USA, African American children residing in rural areas are disproportionately affected by childhood obesity. One strategy for preventing childhood obesity is helping caregivers to recognize their child is overweight or obese. The purpose of this study is to assess African American caregivers' perceived level of their child's obesity status and concordance between caregiver's reported height and weight of their children compared to the objective measure of their child's height and weight. Caregivers completed a paper-based survey about perceptions of their child's weight status including body silhouettes (n = 119) and self-reported their child's body mass index status (n = 68). Children's (n = 71) height and weight were objectively measured. Spearman rho and independent sample t tests were calculated to assess the relationship between caregiver's self-reported and objective BMI status. Caregiver's visually perceived their child's weight status to be underweight; yet, self-reported that their child's body mass index status was obese. The Spearman's rho correlation indicated a significant relationship between caregiver's self-reported and objective body mass index (r = .39, p child's body mass index.

    2010-01-01

    Diabetes around the globe results in one major limb amputation every 30 seconds, over 2500 limbs lost per day. The underlying pathophysiology sometimes leads to a chronic inflammatory stage, which may prevent appropriate healing, and therefore, the need for a clear strategy for assessing and classifying wounds and wound healing cannot be overstated. Temperature is a surrogate marker for inflammation. Quantitative thermography using a numerical index provides a useful way to assess wound healing. Advances in technology have afforded the availability of low-cost, high-resolution thermal imaging systems, which can be used to quantify sensitive changes on the skin surface and may be particularly useful to develop monitoring strategies for wounds. This article provides a standardized technique for calculating a thermal index (TI) supported with a case report from assessment of a diabetic foot ulcer. In this single case study, the TI/wound inflammatory index indicates a shift from negative to positive (p < .05) before it reaches zero. PMID:20663437

  14. Graphical Methodology of Global Pollution Index for the Environmental Impact Assessment Using Two Environmental Components

    2017-04-01

    Full Text Available One of the applied methods for environmental impact assessment is the index of global pollution (IGP proposed by Rojanschi in 1991. This methodology enables the global estimation for the ecosystem state affected more or less by human activities. Unfortunately, Rojanschi’s method has a limitation; it can be applied only if at least three environmental components are considered. Frequently, many environmental impact assessment applications rely on analysis of only two environmental components. Therefore, this work aimed to develop a new graphical method to extend Rojanschi’s approach for the case of two environmental components. The proposed method avoids the average value of evaluation grades and uses only the graphical correspondence for calculation of the index of global pollution. A right-angle triangle graph methodology was proposed, where bases represented the values of evaluation grades. Thus, for the case of two environmental components, the index of global pollution was calculated as the relation between the ideal and real ecosystem states represented by the ratio between areas of external and enclosed right triangles. The developed graphical method was tested and validated for real case studies: the environmental impact assessment from a refinery located on the Romanian Black Sea Coast considering Air and Water environmental components and from a coal-fired thermoelectric power plant from Eastern Romania regarding Air and Soil environmental components. In this way, it was provided a reliable and faster tool to be used for the pollution characterization of human-derived chemicals for better decisions in risk management.

    Summary: We present a review of microvascular dysfunction in hypertrophic cardiomyopathy (HCM) and an interesting case of a symptomatic familial HCM patient with inducible ischemia by single photon emission computed tomography. Coronary angiography revealed normal epicardial arteries. Pressure wire measurements of fractional flow reserve (FFR), coronary flow reserve (CFR) and index of microvascular resistance (IMR) demonstrated a significant microcirculatory dysfunction. This is the first such case that documents this abnormality invasively using the IMR. The measurement of IMR, a novel marker of microcirculatory dysfunction, provides novel insights into the pathophysiology of this condition. - Highlights: • Microvascular dysfunction is a common feature in hypertrophic cardiomyopathy (HCM) and represents a strong predictor of unfavorable outcome and cardiovascular mortality. • The index of microvascular resistance (IMR) is a new method for invasively assessing the state of the coronary microcirculation using a single pressure-temperature sensor-tipped coronary wire. • However assessment of IMR in HCM has not been previously reported. We report a case in which microvascular dysfunction is assessed by IMR. This index may be useful in future researches of HCM.

    -In 2013 the American Society of Clinical Oncology and College of American Pathologists updated the HER2 guidelines and changed the equivocal category for HER2 in situ hybridization testing to an average HER2 copy number of 4.0 to 5.9 with a HER2:CEP17 ratio of less than 2.0 and proposed retesting, with an option of using another control probe to avoid false-negative results. RAI1, located at band position 17p11.2, is a popular alternate probe locus for retesting equivocal changes. -To review experience with the RAI1 alternate probe in HER2 fluorescence in situ hybridization equivocal breast cancers. -Primary and metastatic breast cancers with equivocal HER2 fluorescence in situ hybridization, retested with an alternate (RAI1) probe, were identified. HER2, RAI1, and CEP17 copy numbers, HER2 to control probe ratios, and genetic heterogeneity were recorded. Hematoxylin-eosin-stained slides were reviewed for type and grade of cancer. -Of 876 cases tested with CEP17 as the reference probe, 97 (11.1%) had equivocal HER2 fluorescence in situ hybridization results. Additional testing with the RAI1 probe classified 39.2% cases (38 of 97) as amplified with a HER2:RAI1 ratio ranging from 2.0 to 3.2 (mean, 2.37); 3.1% (3 of 97) were still unclassifiable because of a deletion of RAI1. -RAI1 identified close to 40% of original HER2 fluorescence in situ hybridization equivocal cases as amplified, making these patients eligible for targeted therapies. It is not known whether guidelines for US Food and Drug Administration-approved probes can be extrapolated to alternate probes when an alternate control probe shows losses or gains. Because of the lack of guidelines for reporting HER2 status with alternate probes, laboratories face challenges in interpreting results.

    Graves' ophthalmopathy (GO) develops or worsens in up to one-third of patients treated with radioactive iodine (RAI) for Graves' hyperthyroidism. We sought to identify the prevalence of development or worsening of GO in patients treated with RAI for Graves' hyperthyroidism and to identify the risk factors associated with that outcome. We identified a retrospective cohort of consecutive patients treated with RAI at Mayo Clinic (Rochester, MN) between 2005 and 2006. We assessed their medical records for evidence of hypothyroidism and development or worsening of GO in the year after therapy. Hypothyroidism was defined as thyrotropin >3.0 mIU/L or free thyroxine thyroid function after RAI administration is a strong predictor for adverse GO outcome. This risk is highest in patients with preexisting GO. We suggest that in order to prevent clinical hypothyroidism and the associated risk for GO, the optimal time for first measurement of fT4 is before 6 weeks after RAI therapy.

  20. Developing a vulnerability index for assessing riverbank erosion in large catchments

    2017-04-01

    Riverbank erosion is a natural process involved in floodplain development, but can have negative impacts such as excessive sediment supply to the river channel, undermining infrastructure and eroding valuable agricultural land. Catchment managers often work with limited budgets and for remediation efforts to be the most effective they should be targeted in areas that are at the highest risk of suffering excessive riverbank erosion. Recent developments in high resolution spatial data capture, such as aerial LiDAR have allowed for much more detailed representation of the riparian area, including the channel location and riparian vegetation. This presentation will propose a new dimensionless index that has been developed to identify and rank sections of river channel according to erosion vulnerability. The index combines information on channel position, slope and curvature extracted from LiDAR-derived DEMs with riparian vegetation cover. It also accounts for the extent of lateral confinement limiting erosion and bank silt-clay composition influencing erodibility. The index is designed to be applied to alluvial channels across large catchments (>500 km2) to support the identification riverbank erosion 'hotspots' at the reach scale (approximating 50-200 m intervals). The performance of the vulnerability index in discriminating actively eroding and non-eroding channel reaches was assessed in the River Lugg catchment, UK. Historic mapping and aerial photographs were used to determine the channel position, slope and riparian vegetation coverage in the 1960s. The index was then calculated for the historic river channel position and compared with ranked metrics of lateral channel change that occurred between the 1960s and present. This approach provides a basis for evaluating the utility of a simple vulnerability index that could be used for prioritising the location of future investments to reduce excessive riverbank erosion in large catchments.

    Full Text Available The paper presents an analysis of basic capability indices for production processes, Cp and Cpk, as well as the Cpm index for processes asymmetric with respect to tolerance limits. A method is presented for the estimation of process admissible asymmetry, when anappropriate PPM level of defective products is to be maintained. It is proved that an unbiased capability assessment for asymmetricprocesses is only feasible if the pair of indices Cp and Cpk is included in the assessment. An example is given of an analysis of data on the production of automotive bearings. The computations were performed with use of the KWSPP program.

    To test the interrater reliability of the revised British Isles Lupus Assessment Group 2004 (BILAG-2004) index for the assessment of systemic lupus erythematosus (SLE) activity. Patients with SLE were recruited from 11 centers. Two physician raters separately assessed the patients' disease activity using the BILAG-2004 index in routine clinical practice. Scores ranged from A (for very active disease) to E (for inactivity). Two reliability exercises were performed. Changes were made to the index after the first exercise (E1), and additional training was provided to the raters before the second exercise (E2). E1 and E2 involved 12 and 14 raters, respectively. Interrater reliability was assessed using kappa statistics and intraclass correlation coefficients. Levels of agreement and the extent of major disagreement were also examined. Major disagreement was defined as a score difference between raters of A versus C, D, or E or B versus D or E. For each exercise, 97 patients were recruited. In E1, the mean age of the patients was 42.3 years (range 18.5-82.2 years), 89.7% were women, and 74.2% were white, 8.2% were Afro-Caribbean, and 13.4% were South Asian, and in E2, the mean age was 43.7 years (range 17.7-75 years), 90.7% were women, and 68% were white, 15.5% were Afro-Caribbean, and 11.3% were South Asian. The mean disease duration was 9.4 years (range 0-32.1 years) for patients in E1 and 10 years (range 0-34.8 years) in E2. There was improvement in the interrater reliability and the level of agreement from E1 to E2. Further improvement was achieved after removal of poorly performing items. The BILAG-2004 index is a reliable tool to assess SLE activity. The use of a well-defined glossary and training of raters are essential to ensure the optimal performance of the index.

A quasi-experimental study was conducted in Chiang Rai Province. The MEI model was designed on the basis of four core components: cognitive behavior therapy, ergonomic education training, stretching exercise, and the foam sleeve broom handle grip. Seventy-five street sweepers volunteered for the screening process on MSD of having level score ≥4 by physiotherapist. Face to face interviews were used mainly in order to diagnose MSD. Physical examination was performed by physiotherapist and physical performance by sports scientist. The findings showed that the MEI model among the intervention group significantly reduced MSD compared with that among control group at exit model and follow-up (P<0.01. This research suggests that the MEI model was appropriate to reduce MSD associated with repetitive movement and awkward postures on task.

    Scholarly books have been a periphery among the objects of study of bibliometrics until recent developments provided tools for assessment purposes. Among scholarly book publishers, University Presses (UPs hereinafter), subject to specific ends and constrains in their publishing activity, might also remain on a second-level periphery despite their relevance as scholarly book publishers. In this study the authors analyze the absolute and relative presence, overlap and uniquely-indexed cases of 503 UPs by country, among five assessment-oriented databases containing data on scholarly book publishers: Book Citation Index, Scopus, Scholarly Publishers Indicators (Spain), the lists of publishers from the Norwegian System (CRISTIN) and the lists of publishers from the Finnish System (JUFO). The comparison between commercial databases and public, national databases points towards a differential pattern: prestigious UPs in the English Speaking world represent larger shares and there is a higher overall percentage of UPs in the commercial databases, while the richness and diversity is higher in the case of national databases. Explicit or de facto biases towards production in English by commercial databases, as well as diverse indexation criteria might explain the differences observed. The analysis of the presence of UPs in different numbers of databases by country also provides a general picture of the average degree of diffusion of UPs among information systems. The analysis of ‘endemic’ UPs, those indexed only in one of the five databases points out to strongly different compositions of UPs in commercial and non-commercial databases. A combination of commercial and non commercial databases seems to be the optimal option for assessment purposes while the validity and desirability of the ongoing debate on the role of UPs can be also concluded.

    Full Text Available The objective of this research paper was to make an assessment of breeding value of performance tested gilts of Swedish Landrace and F1 crossbreds of Swedish Landrace and Great Yorkshire by the method of selection index. The traits on whose basis the breeding value was estimated were: daily liveweight gain, average backfat thickness measured at two sites and carcass meat percentage. These traits were corrected for body mass of 100kg by the method of base indexes and the following average values were determined: corrected daily liveweight gain (KZDP 408.93g/day, corrected average backfat thickness measured at two sites (KSL 9.77mm and corrected carcass meat percentage (KPM 61.08%. Studying the effect of genotype, year and birth season of gilts a statistically significant variation (P>0.05 of these traits provoked by the mentioned factors was not determined while the gilts` sire statistically highly significantly (P<0.001 influenced all studied traits. Heritability coefficients were: h2= 0.255 for KZDP, h2= 0.356 for KSL and h2 = 0.349 for KPM. The four selection index equations were constructed among which as the most optimal was chosen the one which includes all three traits (KZDP, KSL and KPM and whose coefficient of the correlation of selection index and aggregate genotype was rIAG = 0.594.

    A vegetation index and radiative surface temperature were derived from NOAA-11 Advanced Very High Resolution Radiometer (AVHRR) data for the Seattle, WA region from 28 June through 4 July 1991. The vegetation index and surface temperature values were computed for locations of weather observation stations within the region and compared to observed minimum air temperatures. These comparisons were used to evaluate the use of AVHRR data to assess the influence of the urban environment on observed minimum air temperatures (the urban heat island effect). AVHRR derived normalized difference vegetation index (NDVI) and radiant surface temperature data from a one week composite product were both related significantly to observed minimum temperatures, however, the vegetation index accounted for a greater amount of the spatial variation observed in mean minimum temperatures. The difference in the NDVI between urban and rural regions appears to be an indicator of the difference in surface properties (i.e., evaporation and heat storage capacity) between the two environments that are responsible for differences in urban and rural minimum temperatures.

    Many household batteries worldwide still end up in landfills or are incinerated due to inefficient collection and recycling schemes. Toxic heavy metals from improperly discarded button cells pose a serious risk to human health and the environment, as they can pollute air, soil and water. This paper analyses a series of button cells selected from batteries available on the retail market, and compares their polluting potential. A total of 64 batteries were subjected to chemical analyses of 19 elements — including metals and metalloids — , and energy density measurements. The samples were from four different brands of each of the four most common button cell technologies (alkaline, zinc-air, silver oxide and lithium). An energy-normalized index — the Weighted Potential Pollution Index (WPPI) — was proposed to compare the polluting potential of the different batteries. The higher the battery WPPI score, the greater the content in toxic elements and the lower the energy output. The results of the chemical composition and energy density varied depending on the construction technology of the button cells. However, significant differences in both variables were also found when comparing different brands within the same technology. The differences in WPPI values confirmed the existence of a significant margin to reduce the environmental impact of discarded button cells simply by avoiding the most polluting options. The choice of the battery with the most favourable WPPI produced a reduction in potential pollution of 3–53% for silver oxide batteries, 4–39% for alkaline, 20–28% for zinc-air and 12–26% for lithium. Comparative potential pollution could be assessed when selecting batteries using an energy-normalized index such as WPPI to reduce the environmental impact of improperly disposed button cells. - Highlights: • We compare the polluting potential of button cells using an energy-normalized index. • This battery index considers both chemical

    Full Text Available Objectives: Assessment of autoimmune cause hypothyroidism and dyslipidemia involvement in the apparition of major vascular complications. Methods: A total of 152 patients were investigated appreciating in comparison to a healthy control lot the hormone serum level, the presence of antimicrosomal thyroid antibodies and the serum levels of lipids. Atherogenic index and coronarian risk were calculated and correlated with the incidence of coronarian and cerebral vascular accidents. Results: Among the patients with goiter it was noted a high incidence of a subclinical hypothyroidism (31,58%. Thyroid autoimmunity was involved in 94,4% of the patients with clinical hypothyroidism, in 93,7 % with subclinical hypothyroidism and 100% in the patients with thyrotoxicosis. Low serum level of HDL-cholesterol was identified in 66,6% of patients with clinical hypothyroidism and 64,5% patients with subclinical hypothyroidism. The assessment of atherogenic index and coronarian risk was significantly higher (p<0,01 in patients with hypothyroidism in comparison to healthy control subjects. The incidence of vascular accidents was significantly higher (p<0,01 among the hypothyroid patients ( 19,7%/ 10,8%, of masculine gender (12,7% where the main cause of hypothyroidism was autoimmunity. Conclusions: The atherogenic index and coronarian risk were higher in patients with hypothyroidism associated to thyroid autoimmunity resulting in an increased probability in producing vascular accidents

  10. A tool for assessing the quality of the Mediterranean cyclone forecast: a numerical index

    2011-06-01

    Full Text Available Cyclones affecting the Mediterranean region, sometimes related to severe weather events, are often not well represented enough in numerical model predictions.

    Assessing the quality of the forecast of these cyclonic structures would be a significant advance in better knowing the goodness of the weather forecast in this region, and particularly the quality of predictions of high impact phenomena.

    In order to estimate the cyclone forecast uncertainty in operational models, in this work we compare two cyclone databases for the period 2006–2007: one from the operational analyses of the T799 ECMWF deterministic model; and the other from the forecasts provided by the same model in three ranges, H+12, H+24, and H+48. The skill of the model to detect cyclones and its accuracy in describing their features are assessed.

    An index is presented as an indicator of the quality of the prediction, derived from the frequency distribution of errors in the prediction of four characteristics of the cyclone: position, central pressure value, geostrophic circulation, and domain. Some sub-indexes are derived to verify each of the variables separately in order to analyse the most frequent sources of error. Other sub-indexes are also defined to indicate possible biases in the numerical prediction model.

    2013-06-01

    Full Text Available A comprehensive analysis of flood risk in mountain streams has to include an assessment of the vulnerability of the protection systems, in addition to an assessment of the vulnerability of the constructed environment on alluvial fans and floodplains. Structures forming the protection systems are of a dual nature, i.e. they are designed to mitigate natural process-related hazards and, on the other hand, are prone to be damaged during their lifecycle by the same processes they should mitigate. Therefore, their effectiveness declines over time. Hence, the knowledge of how effectively control structures perform is essential for risk management. A procedure was developed to assess the physical vulnerability of check dams based on empirical evidence collected in South Tyrol, Northern Italy. A damage index defined on pre- and postevent comparisons of check dam conditions was evaluated for 362 structures in 18 mountain streams along with the relevant processes and the structural characteristics affecting it. Although the available dataset did not allow conclusive functional relationships between damage index and impact variables to be established, it was possible to assess the average expected residual functionality of check dams according to structure characteristics, and event type and intensity. These results may help plan appropriate check dam maintenance.

    Drought is a major cause of crop yield loss, both in rainfed and irrigated agroecosystems. In past decades, many approaches have been developed to assess agricultural drought, usually based on the monitoring or modelling of the soil water content condition. All these indices show weaknesses when applied for a real time drought monitoring and management at the local scale, since they do not consider explicitly crops and soil properties at an adequate spatial resolution. This work describes a newly developed agricultural drought index, called Transpirative Deficit Index (D-TDI), and assesses the results of its application over a study area of about 210 km2 within the Po River Plain (northern Italy). The index is based on transforming the interannual distribution of the transpirative deficit (potential crop transpiration minus actual transpiration), calculated daily by means of a spatially distributed conceptual hydrological model and cumulated over user-selected time-steps, to a standard normal distribution (following the approach proposed by the meteorological index SPI - Standard Precipitation Index). For the application to the study area a uniform maize crop cover (maize is the most widespread crop in the area) and 22-year (1993-2014) meteorological data series were considered. Simulation results consist in maps of the index cumulated over 10-day time steps over a mesh with cells of 250 m. A correlation analysis was carried out (1) to study the characteristics and the memory of D-TDI and to assess its intra- and inter-annual variability, (2) to assess the response of the agricultural drought (i.e., the information provided by D-TDI) to the meteorological drought computed through the SPI over different temporal steps. The D-TDI is positively auto-correlated with a persistence of 30 days, and positively cross-correlated to the SPI with a persistence of 40 days, demonstrating that D-TDI responds to meteorological forcing. Correlation analyses demonstrate that soils

    RGB images of rosacea were analyzed using segmentation maps of principal component analysis (PCA) and erythema index (EI). Areas of segmented clusters were compared to Clinician's Erythema Assessment (CEA) values given by two dermatologists. The results show that visible blood vessels are segmented more precisely on maps of the erythema index and the third principal component (PC3). In many cases, a distribution of clusters on EI and PC3 maps are very similar. Mean values of clusters' areas on these maps show a decrease of the area of blood vessels and erythema and an increase of lighter skin area after the therapy for the patients with diagnosis CEA = 2 on the first visit and CEA=1 on the second visit. This study shows that EI and PC3 maps are more useful than the maps of the first (PC1) and second (PC2) principal components for indicating vascular structures and erythema on the skin of rosacea patients and therapy monitoring.

    Full Text Available In this paper a new concept for control and performance assessment of compressed air energy storage (CAES systems in a hybrid energy system is introduced. The proposed criterion, based on the concept of energy harvest index (HEI, measures the capability of a storage system to capture renewable energy. The overall efficiency of the CAES system and optimum control and design from the technical and economic point of view is presented. A possible application of this idea is an isolated community with significant wind energy resource. A case study reveals the usefulness of the proposed criterion in design, control and implementation of a small CAES system in a hybrid power system (HPM for an isolated community. Energy harvested index and its effectiveness in increasing the wind penetration rate in the total energy production is discussed.

    The hygienic regulations of academic books, including teachware, for children and adolescents necessitate the performance of special studies to assess their readability by the unified procedure that would suggest a visual response while reading. This study has developed and warranted a universal readability index by the velocity of reading. There are significant regression correlations between the velocity of reading as the readability index and the degree of tiredness, detected by various visual functions. The parameters of accommodation and adaptive properties of the eye are most sensitive to visual load on reading. Reading velocity as an indicator of readability of illogical texts may be used as a rapid method under laboratory and natural conditions to determine the action of various textual loads on the visual system.

  19. Assessing pricing assumptions for weather index insurance in a changing climate

    Full Text Available Weather index insurance is being offered to low-income farmers in developing countries as an alternative to traditional multi-peril crop insurance. There is widespread support for index insurance as a means of climate change adaptation but whether or not these products are themselves resilient to climate change has not been well studied. Given climate variability and climate change, an over-reliance on historical climate observations to guide the design of such products can result in premiums which mislead policyholders and insurers alike, about the magnitude of underlying risks. Here, a method to incorporate different sources of climate data into the product design phase is presented. Bayesian Networks are constructed to demonstrate how insurers can assess the product viability from a climate perspective, using past observations and simulations of future climate. Sensitivity analyses illustrate the dependence of pricing decisions on both the choice of information, and the method for incorporating such data. The methods and their sensitivities are illustrated using a case study analysing the provision of index-based crop insurance in Kolhapur, India. We expose the benefits and limitations of the Bayesian Network approach, weather index insurance as an adaptation measure and climate simulations as a source of quantitative predictive information. Current climate model output is shown to be of limited value and difficult to use by index insurance practitioners. The method presented, however, is shown to be an effective tool for testing pricing assumptions and could feasibly be employed in the future to incorporate multiple sources of climate data.

    Foot anthropometry may be altered during pregnancy. Pregnant women often report lower-extremity pain that may be related to these alterations. The Arch Height Index Measurement System is a common method of foot arch assessment; however, the required calipers are costly and are not widely available. Thus, we compared the reliability of a digital photogrammetry method of arch height index (AHI) assessment with that of the Arch Height Index Measurement System. Ten pregnant women (mean ± SD: age, 29 ± 4 years; height, 166.9 ± 6.8 cm; weight, 63.3 ± 8.8 kg) in their second trimester were recruited to participate, along with a control group of 10 nulliparous weight-matched women (mean ± SD: age, 22 ± 2 years; height, 164.6 ± 4.8 cm; weight, 61.5 ± 8.1 kg). During the second and third trimesters, and once postpartum, AHI was assessed using calipers and using digital photogrammetry. Mixed model absolute agreement type intraclass correlation coefficient (ICC) was used to determine correlation between the two methods for sitting and standing AHI. The ICC results for sitting AHI only (0.819-0.968) were reasonable for clinical measures; ICC values for standing AHI (0.674-0.789) did not reach values deemed reasonable for clinical use. Caliper and digital photogrammetry methods of AHI assessment are correlated in pregnant women; however, for standing AHI, the correlation is not sufficient for clinical use. Photogrammetry may still be appropriate for clinical use, as long as values from this method are not substituted directly for results obtained from calipers.

    The design of layout plans requires adequate assessment tools for the quantification of safety performance. The general focus of the present work is to introduce an inherent safety perspective at different points of the layout design process. In particular, index approaches for safety assessment and decision-making in the early stages of layout design are developed and discussed in this two-part contribution. Part 1 (accompanying paper) of the current work presents an integrated index approach for safety assessment of early plant layout. In the present paper (Part 2), an index for evaluation of the hazard related to the potential of domino effects is developed. The index considers the actual consequences of possible escalation scenarios and scores or ranks the subsequent accident propagation potential. The effects of inherent and passive protection measures are also assessed. The result is a rapid quantification of domino hazard potential that can provide substantial support for choices in the early stages of layout design. Additionally, a case study concerning selection among various layout options is presented and analyzed. The case study demonstrates the use and applicability of the indices developed in both parts of the current work and highlights the value of introducing inherent safety features early in layout design.

    2015-05-01

    Full Text Available Drought assessment is essential for coping with frequent droughts nowadays. Owing to the large spatio-temporal variations in hydrometeorology in most regions in China, it is very necessary to use a physically-based hydrological model to produce rational spatial and temporal distributions of hydro-meteorological variables for drought assessment. In this study, the large-scale distributed hydrological model Variable Infiltration Capacity (VIC was coupled with a modified standardized runoff index (SRI for drought assessment in the Weihe River basin, northwest China. The result indicates that the coupled model is capable of reasonably reproducing the spatial distribution of drought occurrence. It reflected the spatial heterogeneity of regional drought and improved the physical mechanism of SRI. This model also has potential for drought forecasting, early warning and mitigation, given that accurate meteorological forcing data are available.

    Chlorine is one of the most produced and most used non-flammable chemical substances in the world even though its toxicity and high reactivity cause the ozone layer depletion. However, in modern life, it is impossible to live a good life without using Chlorine and its derivatives since they are being used as an typical ingredient in more than 40 percent of the manufactured goods including medicines, detergents, deodorant, fungicides, herbicides, insecticides, and plastic, etc. Even if Chlorine has been handled and distributed in various business (small and medium-sized businesses, water purification plants, distribution company, etc.), there have been few researches about its possible health hazard and transportation risks. Accordingly, the purpose of this paper is to make a detailed assessment of Chlorinerelated risks and to model an index of chemicals transportation risks that is adequate for domestic circumstances. The assessment of possible health hazard and transportation risks was made on 13 kinds of hazardous chemicals, including liquid chlorine. This research may be contributed to standardizing the risk assessment of Chlorine and other hazardous chemicals by using an index of transportation risks.

    After critical examination of several aspects relating to the evaluation of some dimensions of emotional intelligence through self-assessment tools, is described the procedure of construction and validation of an Index for its measurement, conceived only for the routine assessment of health promotion programs mental in schools that include among their objectives the improvement of emotional intelligence specifically "outcome-oriented". On the basis of the two most common international tools, are listed 27 items plus 6 of control, illustrated two Focus Group (FG) of students (face validity). The scale obtained by FG was administered to 300 students, and the results were submitted to factorial analysis (construct validity). It was also evaluated the internal consistency with Cronbach's Alpha and studied concurrent validity with the emotional quotient inventory, a scale of perceived self-efficacy and a stress test rating. From the analysis of FG all the original items were modified, deleted 4, and reduced the encoding system from 6 to 4 levels of Likert scale. Of the 23 items included in the analysis have emerged five factors (intra-psychic dimension, interpersonal, impulsivity, adaptive coping, sense of self-efficacy) for a total of 15 items. Very satisfactory were the results of the validation process of internal consistency (0.72) and the concurrent validity. The results are positive. It is obtained in fact the shortest routine assessment tool currently available in Italy which constitutes a real Index, for which compilation are required on average 3 minutes. Is emphasized the characteristic of an Index, and not of questionnaire or interview for clinical use, highlighting the only specific use for mental health promotion programs in schools.

    Hand tremor often causes disability in patients with essential tremor (ET). Aim of the study was to investigate whether tremor magnitude, a new single quantitative score obtained from digital tablet recordings of writing and drawing, is able to adequately reflect disability in ET patients. Mean tremor magnitude values showed significant difference between 14 ET patients and 14 healthy age matched controls (p<0.0001). The tremor magnitude values showed significant correlation with standard methods of clinical assessment (p<0.01). We present tremor magnitude as an index that reflects disability resulting from tremor and can help to evaluate ET.

    To identify cutoff points of the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index established for adolescents and discuss their applicability for the diagnosis of insulin resistance in Brazilian adolescents. A systematic review was performed in the PubMed, Lilacs and SciELO databases, using the following descriptors: "Adolescents", "insulin resistance" and "ROC curve". Original articles carried out with adolescents published between 2005 and 2015 in Portuguese, English or Spanish languages, which included the statistical analysis using ROC curve to determine the index cutoff (HOMA-IR) were included. A total of 184 articles were identified and after the study phases were applied, seven articles were selected for the review. All selected studies established their cutoffs using a ROC curve, with the lowest observed cutoff of 1.65 for girls and 1.95 for boys and the highest of 3.82 for girls and 5.22 for boys. Of the studies analyzed, one proposed external validity, recommending the use of the HOMA-IR cutoff >2.5 for both genders. The HOMA-IR index constitutes a reliable method for the detection of insulin resistance in adolescents, as long as it uses cutoffs that are more adequate for the reality of the study population, allowing early diagnosis of insulin resistance and enabling multidisciplinary interventions aiming at health promotion of this population.

    Full Text Available Groundwater as a source of potable water is becoming more important in Nigeria. Therefore, the need to ascertain the continuing potability of the sources cannot be over emphasised. This study is aimed at assessing the quality of selected groundwater samples from Ilorin metropolis, Nigeria, using the water quality index (WQI method. Twenty two water samples were collected, 10 samples from boreholes and 12 samples from hand dug wells. All these were analysed for their physico – chemical properties. The parameters used for calculating the water quality index include the following: pH, total hardness, total dissolved solid, calcium, fluoride, iron, potassium, sulphate, nitrate and carbonate. The water quality index for the twenty two samples ranged from 0.66 to 756.02 with an average of 80.77. Two of the samples exceeded 100, which is the upper limit for safe drinking water. The high values of WQI from the sampling locations are observed to be due to higher values of iron and fluoride. This study reveals that the investigated groundwaters are mostly potable and can be consumed without treatment. Nonetheless, the sources identified to be unsafe should be treated before consumption.

    The present study proposes a novel technique to assess dynamic recrystallization (DRX) and related microstructural phenomena during hot deformation of austenite. A `Flow Softening Index (FSI)' has been identified on the basis of investigations on elevated temperature deformation behaviour of austenitic stainless steel. This index corresponds to dominant microstructural phenomena at different deformation conditions. For this investigation, experimental results obtained from isothermal, constant true strain rate compression tests in a temperature range of 1173 (900)-1473 K (1200 °C) and strain rate range of 0.01-100 s-1 have been used. Resultant microstructures have been quantified using average grain size and grain size distributions. The dominant microstructural phenomena have been identified at different conditions using electron backscatter diffraction. Low FSI values are associated with the grain growth, intermediate values with DRX, and high values with the work-hardening and flow localisation phenomena. FSI also quantitatively indexes the average grain size and grain size distributions at different temperature-strain rate combinations. Analysis of the specific deformation conditions, particularly where 3.4 < FSI < 3.5, indicates a common thermo-mechanical origin of flow localisation and DRX. The potential technological implications thereof are discussed and a semi-empirical model of microstructural evolution is developed for the studied material.

    Full Text Available Background and Aim: Extensive studies on the epidemiology of teeth and oral diseases are an important part of health care programs specially for hearing impaired groups. For adequate programming in this field, proper situation analysis is mandatory. The aim of this study was to assess the DMFT (decayed missed filled teeth of 12 years old students attending hearing impaired schools in Tehran and exploring the relation between sex, hygiene and hearing threshold with the index. Materials and Methods: This cross sectional descriptive study was based on examining 12 years old (± 6 month students (117 cases attending hearing impaired schools in Tehran. A questionnaire was filled for each case. T, Chi-square and Kruskall-Wallis tests were used to analyze the results with p<0.05 as the limit of significance. Results: The mean DMFT in these students was 3.07. Mean DMFT in students with very severe hearing loss was 2.99. Mean ranked DMFT in girls and boys was similar (56.09 in boys and 61.96 in girls. Mean ranked DMFT in students who didn’t use floss (66.40 was higher than those who used floss (46.71. Mean ranked DMFT in students who seldom brushed, was the highest (72.82 and in students who brushed once a day was the lowest (51.26. Conclusion: The DMFT index in hearing disabled children was 3.07. Regular brushing and flossing reduced the index.

    2001-03-01

    The transferrin receptor-ferritin index (sTfR/logFerr) was determined in 131 male and 121 female athletes in order to assess the frequency of iron deficiency (threshold value of that index taken as 1.8). Blood was drawn for determining morphological indices as well as sTfR, ferritin, iron, total iron binding capacity (TIBC), and haptoglobin. A significantly (p iron deficiency was observed in women (26%) than in men (11%). The iron deficiency was latent, since no subject was found to be anemic. The plasma iron was significantly lower and TIBC higher (p iron-deficient subgroups than in the non-deficient ones. This confirmed the latent character of iron deficiency. Some hematological indices (Hb, MCH, MCHC, MCV) were significantly lower in iron-deficient female athletes than in male athletes, which suggested a more profound iron deficiency in the former. The sTfR/logFerr index might thus be useful in detecting iron deficiency in athletes, especially in those with erythropoiesis disorders, since physical loads may affect the widely used ferritin levels.

    The paper presents new concept of poverty risk index measurement due to dynamics of urban development among years. The rapid urbanization could seriously surpass the capacity of the most cities, which may lead to insufficient services of their inhabitants. Consequence of this situation could be polarized, social differentiated cities with high rates of urban poverty. The measurement and analysis of urban poverty phenomenon requires the dedicated tools and techniques. The data based assessment could allow planners and public policy makers to develop more socially integrated cities. This paper presents analysis of urban poverty phenomenon in Wrocław city (Poland) during period 2010-2012. This analysis was conducted for ten Social Assistance Terrain Units (SATU) delineated at the city area. Our primary study objective concerns the proposal and calculation of poverty risk index based on diagnostic features, which represent the most common causes of social benefits granting, as: number of single households granted permanent benefits, number of people in families granted permanent benefits, number of people in families granted temporary benefits due to unemployment, number of people in families granted temporary benefits due to disability, number of people in families granted meals for children. The calculation was conducted by using the theory of development pattern - Hellwig’s economic development measure. The analysis of poverty risk index showed that commonly the central and south-eastern part of the city is characterized by the highest poverty risk index. The obtained results of the inequalities spatial distribution relate to European and American patterns of poverty concentration in urban structures.

    Agriculture is a major sector in India which contributes around 14% of country's gross domestic product (GDP). Being an agriculture-based country, good quality of water for irrigation has been a prime requisite. Highly growing population and accelerated industrial development are causing anthropogenic pollution to both surface and groundwater on one side and geogenic contamination like arsenic, fluoride, high dissolved solids, sodicity, and iron in groundwater on other side. As a result, ensuring safe water quality for the irrigation has become a major challenge to both the central and state governments. The present irrigation water quality standards being followed in India have been set by the Central Pollution Control Board (CPCB) and Central Ground Water Board (CGWB) in the year 2000. These standards are solely based on four parameters, namely electrical conductivity, sodium percentage, sodium absorption ratio, and residual sodium carbonate, which are quite subjective and many times are not capable to exactly decide the quality of irrigation water particularly when there are large variations in the source water quality. Therefore, in the present paper, an indices-based approach is presented for categorization of irrigation water quality. These indices are mathematical equations that transform water quality data into a numeric value, which describes the quality of irrigation water. The proposed irrigation water quality index (IWQI), which is based on 12 parameters, classifies the water into five categories, viz. excellent, good, medium, bad, and very bad in the same manner as given by the CPCB and CGWB. In order to give proper rating to various parameters of the index, weights are computed using Saaty's analytic hierarchy process (AHP)-based multiple criteria decision analysis (MCDA) approach. This approach minimizes the subjectivity in assessment of weights and improves understanding of water quality issues by generating an overall index to describe the status

  16. Using a Lethality Index to Assess Susceptibility of Tribolium confusum and Oryzaephilus surinamensis to Insecticides.

    Paraskevi Agrafioti

    Full Text Available We evaluated knockdown caused by four insecticides: alpha-cypermethrin, chlorfenapyr, pirimiphos-methyl and fipronil against adults of Tribolium confusum Jacquelin Duval, the confused flour beetle and Oryzaephilus surinamensis (L., the sawtoothed grain beetle. Bioassays were conducted on concrete and metal surfaces. Adults of the tested species were exposed on both surfaces treated with the above insecticides at two doses (low and high. Knockdown assessment was done after 15, 30 and 60 min of adult exposure in the treated surfaces. Also, after 1, 3, 5, 7 and 14 d of exposure, a lethality index was calculated with an equation resulting to values from 0 to 100, where 100 indicated complete mortality and 0 complete survival. We also developed a lethality index by ranking each adult on each surface from 0 to 4, 0: adults moved normally, 1: adults were knocked down, but were able to walk for short intervals, 2: adults were knocked down and unable to walk, but with visible movement of antennae etc., 3: adults were knocked down, with very minimal movement of the tarsi and the antennae and 4: adults were dead (no movement. Knockdown of adults immediately after exposure (15-60 min was higher for pirimiphos-methyl followed by alpha-cypermethrin, for both dose rates tested and species, but only on the metal surface. The lethality index was nearly 100 for all insecticides after 5d of exposure for O. surinamensis, while for T. confusum the adult lethality index was considerably lower for alpha-cypermethrin, suggesting that that recovery from knockdown occurred. Chlorfenapyr was the only insecticide that was more effective on concrete than on metal, while the reverse was noted for the other three insecticides. These results show that knockdown has different levels, which can be used as indicators of insect mortality or recovery.

    Full Text Available Iran is located in an arid and semi-arid part of the world. Accordingly, the management of the water resources in the country is a priority. In this regard, determining the quality and pollution of surface water and groundwater is very important, especially in areas where groundwater resources are used for drinking. Groundwater quality index (GQI checks the components of the available water with various quality levels. To assess the quality of drinking groundwater of Yazd-Ardakan plain according to GQI in geographical information system (GIS environment, the electrical conductivity, sodium, calcium, magnesium, chlorine, pH, sodium adsorption ratio, bicarbonate, sulfate, potassium, water hardness, and all substances dissolved in the waters of 80 wells were determined. The samples were obtained from Yazd Regional Water Organization from 2005 to 2014. Using this data, the map components were plotted by Kriging geostatistical method. Then, the map of GQI was prepared after normalizing each map component, switching to a rating map, and extracting the weight of each component from the rating map. Based on the GQI index map, the index point which was 87 in 2005 has increased to 81 in 2014. These maps show a decline in groundwater quality from west to the east region. This decline in groundwater quality is due to the existence of Neogene Organizations in the east and geomorphologic unit of the bare epandage pediment in the west. The map removal and single-parameter sensitivity analysis showed that GQI index in Yazd-Ardakan plain is more sensitive to the components of electrical conductivity (EC, total dissolved solids (TDS, and total hardness (TH. Therefore, these components should be monitored more carefully and repeatedly.

    A common way of quantifying and communicating climate vulnerability is to calculate composite indices from indicators, visualizing these as maps. Inherent methodological uncertainties in vulnerability assessments, however, require greater attention. This study examines Swedish agricultural vulnerability to climate change, the aim being to review various indicator approaches for assessing agricultural vulnerability to climate change and to evaluate differences in climate vulnerability depending on the weighting and summarizing methods. The reviewed methods are evaluated by being tested at the municipal level. Three weighting and summarizing methods, representative of climate vulnerability indices in general, are analysed. The results indicate that 34 of 36 method combinations differ significantly from each other. We argue that representing agricultural vulnerability in a single composite index might be insufficient to guide climate adaptation. We emphasize the need for further research into how to measure and visualize agricultural vulnerability and into how to communicate uncertainties in both data and methods.

    There is no clear knowledge towards the collective risk associated with multivariate extremes for natural and human systems, as the research thus far has not taken into account the combined impact of changes in hot, cold, wet and dry extremes. Concurrently, not all the factors influencing human vulnerability to climate change are related with natural system's response to climate forcing as future changes in both the magnitude and the distribution of human population and income levels can potentially multiply or reduce the risk of human exposure to climatic changes. For a comprehensive socio-climate risk assessment, a county-level integrated vulnerability index is developed in this study to provide an estimate of future exposure to both changes in climate extremes and socioeconomic conditions over the continental United States. The integrated vulnerability index is based on the combination of a unified climate extremes indices, which summarize overall exposure to multivariate and multidimensional climate extremes, including hot, cold, wet and dry, and shared socioeconomic pathways, which identify communities at risk based on projected population and income levels. We will present results from the application of the proposed integrated vulnerability index on a high-resolution (4km) 11-member ensemble of regional climate simulations and multiple socioeconomic pathways, aggregated at county scale, which cover 1966-2005 in the baseline and 2011-2050 in the near-term future climate under Representative Concentration Pathway 8.5. Overall, this research should help advance robust strategies for assessing the risk and vulnerability associated with projected changes in temperature and precipitation characteristics, as well as socioeconomic conditions.

    The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the period from 2004 to 2014. A total of over 300 groundwater samples were analysed for pH, EC, PAH, TOC, Cr, Hg, Zn, Pb, Cd, Cu, as required by the UE legal acts for landfill monitoring system. The calculated values of the LWPI allowed the quantification of the overall water quality near the landfill sites. The obtained results indicated that the most negative impact on groundwater quality is observed near the old Landfill H. Improper location of piezometer at the Landfill S favoured infiltration of run-off from road pavement into the soil-water environment. Deep deposition of the groundwater level at Landfill S area reduced the landfill impact on the water quality. Conducted analyses revealed that the LWPI can be used for evaluation of water pollution near a landfill, for assessment of the variability of water pollution with time and for comparison of water quality from different piezometers, landfills or time periods. The applied WQI (Water Quality Index) can also be an important information tool for landfill policy makers and the public about the groundwater pollution threat from landfill.

    Concepts for medicinal plants are represented by a variety of associated general terms with specific indexing patterns in databases, which may not consistently reflect growth of records. The objectives of this study are to assess the development in databases by identifying general terms that describe herbal medicine with optimal retrieval recall and to identify possible special trends in co-occurrence of specific and general concepts. Different search strategies are tested in cab abstracts, medline and web of science. Specific terms (Origanum and Salvia) are employed. Relevant general terms (e.g. 'Plants, Medicinal', Phytotherapy, Herbal drugs) are identified, along with indexing trends and co-occurrences. Growth trends, in specific (narrower) terms, are similar among databases. General terms, however, exhibit dissimilar trends, sometimes almost opposing one another. Co-occurrence of specific and general terms is changing over time. General terms may not denote definite development of trends as the use of terms differs amongst databases, making it difficult to correctly assess possible numbers of relevant records. Perceived increase can, sometimes, be attributed to an increased occurrence of a more general term alongside the specific one. Thesaurus-controlled databases may yield more hits, because of 'up-posted' (broader) terms. Use of broader terms is helpful as it enhances retrieval of relevant documents. © 2012 The authors.

    The coastal communities of the central Gulf of Mexico (GOM) form a highly productive and complex human, physical, and natural environment that interact in ways unique compared to other coastal areas of the globe. Past studies on understanding coastal resiliency and developing vulnerability indices for this region have mainly focused on climate change and sea-level rise, with more recent research directed towards recognizing socio-economic and demographic factors. The interactions of climate change and non-climatic drivers of the coastal ecosystem such as economy and infrastructure concentration are often overlooked. To support the development of policies relating to coastal management and climate change, it is vital to integrate all the relevant parameters. This paper presents a relative vulnerability assessment of the central GOM coast by incorporating climatic, geological, socio-economic, demographic and economic variables. A multi-dimensional Coastal Vulnerability Index (CVI) developed from these parameters is used to rate coastal segments into different classes based on their range of vulnerability. We study the relationship between energy infrastructure and the physical and human aspects of communities to identify and prioritize communities, and the proximate infrastructure most at risk from coastal climate change. Spatial analysis will be a component part of this index-based approach to characterize, organize, and analyze data for assessing coastal community vulnerability in areas supporting critical energy infrastructure. Special focus is directed towards the concentration of pipeline and transportation infrastructure in this region.

  7. Environmental status assessment using DNA metabarcoding: towards a genetics based Marine Biotic Index (gAMBI.

    Full Text Available Marine ecosystem protection and conservation initiatives rely on the assessment of ecological integrity and health status of marine environments. The AZTI's Marine Biotic Index (AMBI, which consists on using macroinvertebrate diversity as indicator of ecosystem health, is used worldwide for this purpose. Yet, this index requires taxonomic assignment of specimens, which typically involves a time and resource consuming visual identification of each sample. DNA barcoding or metabarcoding are potential harmonized, faster and cheaper alternatives for species identification, although the suitability of these methods for easing the implementation of the AMBI is yet to be evaluated. Here, we analyze the requirements for the implementation of a genetics based AMBI (gAMBI, and show, using available sequence data, that information about presence/absence of the most frequently occurring species provides accurate AMBI values. Our results set the basics for the implementation of the gAMBI, which has direct implications for a faster and cheaper marine monitoring and health status assessment.

    Psoriasis is a chronic inflammatory disease of the skin that affects patients of all ages and both genders. The impact of the disease on quality of life is greater among patients with moderate to severe psoriasis. to establish a correlation between the psoriasis area and severity index (PASI) and the Dermatology Life Quality Index (DLQI) based on a quality of life questionnaire adapted to the Brazilian context for patients with plaque psoriasis before and after systemic treatment. This was a cross-sectional, descriptive study of psoriasis patients who did not undergo treatment or who manifested clinical activity of the disease. Patients were evaluated according to the PASI and the quality of life questionnaire adapted to the Brazilian context before and 60 days after systemic treatment. Thirty-five patients participated in the study. Twenty-six were men, with a mean age of 46 years. There was no correlation between the PASI and the quality of life questionnaire adapted to the Brazilian context, but there was a correlation between the PASI and some items of the quality of life questionnaire adapted to the Brazilian context, such as jobs involving public contact. The non-correlation between the PASI and the quality of life questionnaire adapted to the Brazilian context in this work may be associated with a history of chronic disease, which implies greater acceptance of the illness, or may be related to the low income and social status of the patients studied. The correlation observed among patients with careers involving public contact suggests that some professions are more impacted by the disease. It may be necessary to adapt the quality of life questionnaire to patients with a low income and cultural and social limitations. The small sample size (n=35 patients) and the short follow-up period of 60 days were some of the limitations of this work.

  9. Nuclear Energy Readiness Indicator Index (NERI): A benchmarking tool for assessing nuclear capacity in developing countries

    Declining natural resources, rising oil prices, looming climate change and the introduction of nuclear energy partnerships, such as GNEP, have reinvigorated global interest in nuclear energy. The convergence of such issues has prompted countries to move ahead quickly to deal with the challenges that lie ahead. However, developing countries, in particular, often lack the domestic infrastructure and public support needed to implement a nuclear energy program in a safe, secure, and nonproliferation-conscious environment. How might countries become ready for nuclear energy? What is needed is a framework for assessing a country's readiness for nuclear energy. This paper suggests that a Nuclear Energy Readiness Indicator (NERI) Index might serve as a meaningful basis for assessing a country's status in terms of progress toward nuclear energy utilization under appropriate conditions. The NERI Index is a benchmarking tool that measures a country's level of 'readiness' for nonproliferation-conscious nuclear energy development. NERI first identifies 8 key indicators that have been recognized by the International Atomic Energy Agency as key nonproliferation and security milestones to achieve prior to establishing a nuclear energy program. It then measures a country's progress in each of these areas on a 1-5 point scale. In doing so NERI illuminates gaps or underdeveloped areas in a country's nuclear infrastructure with a view to enable stakeholders to prioritize the allocation of resources toward programs and policies supporting international nonproliferation goals through responsible nuclear energy development. On a preliminary basis, the indicators selected include: (1) demonstrated need; (2) expressed political support; (3) participation in nonproliferation and nuclear security treaties, international terrorism conventions, and export and border control arrangements; (4) national nuclear-related legal and regulatory mechanisms; (5

  10. The Modified Fouling Index Ultrafiltration constant flux for assessing particulate/colloidal fouling of RO systems

    2015-02-18

    Reliable methods for measuring and predicting the fouling potential of reverse osmosis (RO) feed water are important in preventing and diagnosing fouling at the design stage, and for monitoring pre-treatment performance during plant operation. The Modified Fouling Index Ultrafiltration (MFI-UF) constant flux is a significant development with respect to assessing the fouling potential of RO feed water. This research investigates (1) the variables influencing the MFI-UF test at constant flux filtration (membrane pore size, membrane material, flux rate); and (2) the application of MFI-UF into pre-treatment assessment and RO fouling estimation. The dependency of MFI on flux, means that to assess accurately particulate fouling in RO systems, the MFI should be measured at a flux similar to a RO system (close to 20 L/m2/h) or extrapolated from higher fluxes. The two studied membrane materials showed reproducible results; 10% for PES membranes and 6.3% for RC membranes. Deposition factors (amount of particles that remain on the surface of membrane) were measured in a full-scale plant ranging between 0.2 and 0.5. The concept of “safe MFI” is presented as a guideline for assessing pre-treatment for RO systems.

    The objective of this study is to assess the reliability of the cardiac index (CI) in healthy pregnant women at term by investigating the correlation between the cardiac output (CO) and the body surface area (BSA) using a novel non-invasive cardiography technique (NICaS™). Sixty-one healthy, normotensive women with a singleton pregnancy at term (≥37 gestational weeks) participated in this prospective observational study between 1/2015 and 6/2015 L. Each woman was assessed for CO by the NICaS™, an impedance device that non-invasively measures the CO and its derivatives. The NICaS™ demonstrated a very good correlation with the gold standard Swan-Ganz catheter. BSA was determined by the Dubois nomogram. The mean ± standard deviation maternal age was 34.2 ± 5.3 years, mean height 166 ± 6 cm, and mean body mass index 23.9 ± 4.9 kg/m2. The mean gestational age was 38.8 ± 0.7 weeks. The correlation between the CO and the BSA was poor (Pearson r = 0.254, p < .005). The current study demonstrated poor correlation between the CO and the BSA in pregnant women, therefore, making the CI a non-reliable variable for assessing CO in pregnant women. We, therefore, suggest that the CO rather than the CI is the preferred parameter for hemodynamic measurements in this population.

    The International Union for Conservation of Nature (IUCN) Red List Index (RLI) is used to measure trends in extinction risk of species over time. The development of 2 red lists for Spanish vascular flora during the past decade allowed us to apply the IUCN RLI to vascular plants in an area belonging to a global biodiversity hotspot. We used the Spanish Red Lists from 2000 and 2010 to assess changes in level of threat at a national scale and at the subnational scales of Canary Islands, Balearic Islands, and peninsular Spain. We assigned retrospective IUCN categories of threat to 98 species included in the Spanish Red List of 2010 but absent in the Spanish Red List of 2000. In addition, we tested the effect of different random and taxonomic and spatial Spanish samples on the overall RLI value. From 2000 to 2010, the IUCN categories of 768 species changed (10% of Spanish flora), mainly due to improved knowledge (63%), modifications in IUCN criteria (14%), and changes in threat status (12%). All measured national and subnational RLI values decreased during this period, indicating a general decline in the conservation status of the Spanish vascular flora. The Canarian RLI value (0.84) was the lowest, although the fastest deterioration in conservation status occurred on peninsular Spain (from 0.93 in 2000 to 0.92 in 2010). The RLI values based on subsamples of the Spanish Red List were not representative of RLI values for the entire country, which would discourage the use of small areas or small taxonomic samples to assess general trends in the endangerment of national biotas. The role of the RLI in monitoring of changes in biodiversity at the global and regional scales needs further reassessment because additional areas and taxa are necessary to determine whether the index is sufficiently sensitive for use in assessing temporal changes in species' risk of extinction. © 2015 Society for Conservation Biology.

    Ambulatory arterial stiffness index (AASI) is a parameter derived from ambulatory blood pressure (ABP) readings. It is calculated as 1 minus the linear slope of DBP on SBP. We tested its value in assessing arterial stiffness in dialysis patients. We performed a cross-sectional analysis of the baseline data from a cohort study. A total of 344 patients on maintenance hemodialysis from six tertiary hospitals were included. All patients underwent ABP monitoring and carotid-femoral pulse wave velocity (cfPWV) measurement. Clinical determinants of AASI were analyzed, and the ability of AASI for assessing arterial stiffness was compared with ambulatory pulse pressure (PP). Multiple regression analysis revealed that ambulatory PP (β = 0.003), current smoker (β = -0.069), age (β = 0.003) and ambulatory SBP (β = 0.001) were independent determinants of AASI. Ambulatory PP correlates better with cfPWV than AASI (r = 0.28 for AASI and 0.59 for PP; P for difference: <0.001). When cfPWV was treated as a categorical variable, receiver operating characteristic curve analysis also showed a more potent predictive value of PP over AASI (area under the curve: 0.64 for AASI, 0.80 for PP; P for difference: <0.001). Net reclassification improvement and integrated discrimination improvement analysis demonstrated no added predictive value of AASI to PP (net reclassification improvement = -2.2%, P = 0.26; integrated discrimination improvement = 0.001, P = 0.51). Sensitivity analysis in patients with more ABP readings (≥49) yielded similar results. For dialysis patients, AASI has very limited value in assessing arterial stiffness, whether used alone or added to PP. Our results suggest that this index should not be used as a surrogate marker of arterial stiffness for dialysis patients in future practice and studies.

    The Millennium Ecosystem Assessment (MA) estimated that two thirds of ecosystem services on the earth have degraded or are in decline due to the unprecedented scale of human activities during recent decades. These changes will have tremendous consequences for human well-being, and offer both risks and opportunities for a wide range of stakeholders. Yet these risks and opportunities have not been well managed due in part to the lack of quantitative understanding of human dependence on ecosystem services. Here, we propose an index of dependence on ecosystem services (IDES) system to quantify human dependence on ecosystem services. We demonstrate the construction of the IDES system using household survey data. We show that the overall index and sub-indices can reflect the general pattern of households' dependences on ecosystem services, and their variations across time, space, and different forms of capital (i.e., natural, human, financial, manufactured, and social capitals). We support the proposition that the poor are more dependent on ecosystem services and further generalize this proposition by arguing that those disadvantaged groups who possess low levels of any form of capital except for natural capital are more dependent on ecosystem services than those with greater control of capital. The higher value of the overall IDES or sub-index represents the higher dependence on the corresponding ecosystem services, and thus the higher vulnerability to the degradation or decline of corresponding ecosystem services. The IDES system improves our understanding of human dependence on ecosystem services. It also provides insights into strategies for alleviating poverty, for targeting priority groups of conservation programs, and for managing risks and opportunities due to changes of ecosystem services at multiple scales.

    Many household batteries worldwide still end up in landfills or are incinerated due to inefficient collection and recycling schemes. Toxic heavy metals from improperly discarded button cells pose a serious risk to human health and the environment, as they can pollute air, soil and water. This paper analyses a series of button cells selected from batteries available on the retail market, and compares their polluting potential. A total of 64 batteries were subjected to chemical analyses of 19 elements - including metals and metalloids - , and energy density measurements. The samples were from four different brands of each of the four most common button cell technologies (alkaline, zinc-air, silver oxide and lithium). An energy-normalized index - the Weighted Potential Pollution Index (WPPI) - was proposed to compare the polluting potential of the different batteries. The higher the battery WPPI score, the greater the content in toxic elements and the lower the energy output. The results of the chemical composition and energy density varied depending on the construction technology of the button cells. However, significant differences in both variables were also found when comparing different brands within the same technology. The differences in WPPI values confirmed the existence of a significant margin to reduce the environmental impact of discarded button cells simply by avoiding the most polluting options. The choice of the battery with the most favourable WPPI produced a reduction in potential pollution of 3-53% for silver oxide batteries, 4-39% for alkaline, 20-28% for zinc-air and 12-26% for lithium. Comparative potential pollution could be assessed when selecting batteries using an energy-normalized index such as WPPI to reduce the environmental impact of improperly disposed button cells.

    2009-02-15

    Dams for leachate store very toxic substances that contain a large amount of organic material and, probably, heavy metals; they therefore constitute an important threat to the environment. Existing models of environmental risk assessment for landfills do not take into consideration the specific risk that leachate dams may represent for the environment. In this paper a methodology to improve the environmental safety is presented according to the parameters used in their construction and management. In order to do that, the following characteristics of the dam must be known: (1) geotechnical stability, (2) erosion of downstream slope, (3) type of sealing of the dam, (4) overtopping probability, (5) volume of leachate stored inside the dam and (6) pollution load of leachate. Once these parameters have been calculated, they are transformed by means of rating curves into homogeneous units, so as to make it possible to operate between them. From the study and analysis of these parameters an environmental risk index for a dam for leachate can be calculated. If the environmental risk index exceeds an established value then it involves a dam for leachate with high environmental risk, therefore preventive measures in its design, construction and management would be necessary.

    Full Text Available Abstract Background Early diagnosis of Osteoarthritis (OA is essential for preventing further cartilage destruction and decreasing severe complications. The aims of this study are to explore the relationship between OA pathological grades and quantitative acoustic parameters and to provide more objective criteria for ultrasonic microscopic evaluation of the OA cartilage. Methods Articular cartilage samples were prepared from rabbit knees and scanned using ultrasound biomicroscopy (UBM. Three quantitative parameters, including the roughness index of the cartilage surface (URI, the reflection coefficients from the cartilage surface (R and from the cartilage-bone interface (Rbone were extracted. The osteoarthritis grades of these cartilage samples were qualitatively assessed by histology according to the grading standards of International Osteoarthritis Institute (OARSI. The relationship between these quantitative parameters and the osteoarthritis grades was explored. Results The results showed that URI increased with the OA grade. URI of the normal cartilage samples was significantly lower than the one of the OA cartilage samples. There was no significant difference in URI between the grade 1 cartilage samples and the grade 2 cartilage samples. The reflection coefficient of the cartilage surface reduced significantly with the development of OA (p Conclusion High frequency ultrasound measurements can reflect the changes in the surface roughness index and the ultrasound reflection coefficients of the cartilage samples with different OA grades. This study may provide useful information for the quantitative ultrasonic diagnosis of early OA.

    Full Text Available From a holistic view, this paper addresses a perspective of coordinated development of economy, society, and environment for regional sustainability assessment. Firstly, a comprehensive indicator system for co-evaluating the level of economic, social, and environmental subsystems is presented based on a holistic understanding of regional sustainability. Then, a coordinated development index model focusing on the level of coordination among the subsystems as well as their comprehensive development level is established. Furthermore, an empirical study of all the provinces and municipalities is conducted by collecting the panel data from 2004 to 2010. The result shows that: (1 the coordinated developments of the most developed and the most underdeveloped regions stay stable while the regions with medium development level possess more fluctuant trends during the study years; (2 regional disparities are indicated according to the grading of CDI (the coordinated development index, which are further analyzed to be related to the local economic development patterns; (3 the conditions and causes of economic, social, and environmental development in real situations under different grades of CDI are discussed through detailed case studies of typical regions, which indicate specific suggestions of sustainable development for regions in the same pattern.

  1. Assessment of silt density index (SDI) as fouling propensity parameter in reverse osmosis (RO) desalination systems

    2013-01-01

    Due to its simplicity, silt density index (SDI) is extensively used in reverse osmosis systems despite its limitations in predicting membrane fouling. Employing a reliable fouling index with good reproducibility and precision is necessary. The aim of this investigation is to assess the reliability of SDI in order to understand the reasons for the low level of precision and accuracy. Different commercial SDI membranes and feed water quality were used in this study. Results showed the existence of membrane properties\\' variation within manufacturers, which then causes a lack of accuracy in fouling risk estimation. The nature of particles during SDI filtration provides information that particle concentration and size play a significant role in SDI quantification with substantial representation given by particles with size close to membrane nominal pore size. Moreover, turbidity-assisted SDI measurements along with determination of ultrafiltration permeate and clean water fouling potential, establish the indication of nonfouling-related phenomena involved on SDI measurement such as natural organic matter adsorption and hydrodynamic conditions that alters during filtration. Additionally, it was found that the latter affects the sensitivity of SDI by being represented by some portions of SDI values. © 2013 Desalination Publications.

    Full Text Available Recent work has established an association between overweight/obesity and sleep duration, suggesting that short sleep duration and timing of sleeping may lead to overweight. Most of these studies considered sleep-length rather than any other aspects associated with the sleep and wake rhythm, e.g. chronotype, which is a measure of timing of sleeping (‘when to sleep’; based on the midpoint of sleep. The objective of this study was to assess the influence of different factors of the sleep-wake cycle and of co-variates on the Body Mass Index in a cross-sectional questionnaire study. Nine hundred and thirteen pupils (406 boys, 507 girls from Southwestern Germany participated in this study. Mean age was 13.7 ± 1.5 (SD years and range was between 11 – 16 years. We found that chronotype (β = .079 and social jetlag (β = .063 showed a significant influence on Body Mass Index (BMI, while sleep duration did not. Social jetlag is the absolute difference between mid-sleep time on workdays and free days. Further, screen time (in front of TV, computer, β = .13 was positively related with BMI. Self-efficacy on nutrition (β = -.11, a psychological variable important in health-behaviour models, showed an influence with high scores on self-efficacy related to lower BMI. A high BMI was correlated with low fast-food consumption (β = -.12 suggesting that adolescents with high BMI may exert some control over their eating.

    The objective of this study was to translate the Geriatric Oral Health Assessment Index (GOHAI) into the Hindi language and assess its validity and reliability for use among people in India. GOHAI was translated into the Hindi language and self-administered to 420 subjects aged 55 years or above. The measures for reliability, and concurrent, convergent, and discriminant validity were assessed. The questionnaire sought information about sociodemographic details, habits related to tobacco, dental visits, tooth brushing, and self-reported perceptions of general and oral health. Cronbach's alpha (0.774) showed high internal consistency and homogeneity between items. Low GOHAI scores were associated with the perceptions of poor oral and general health, low satisfaction with oral health, and a perceived need for dental care. Respondents with high socioeconomic status were likely to have high GOHAI scores. The Hindi version of the GOHAI demonstrated acceptable validity and reliability, and will be an important instrument to measure oral health-related quality of life (OHRQoL) for people in this region.

    Mental health problems, particularly depression, are a major risk factor for suicide. Currently, there is no way to predict, with 100% accuracy, who will make a suicide attempt, but during a clinical interview, it is possible to assess the risk presented by each patient based on the investigation of risk and protective factors. The assessment of these factors helps health care professionals make decisions on the interventions to put into practice, thus contributing to reducing risk. The use of suicide risk assessment tools, properly validated for the population under consideration facilitate communication and information gathering, with clinical nurse specialists in mental health playing an important role. Because of the shortage of suicide risk assessment tools properly validated for the Portuguese population, it was our aim to translate, adapt and validate the Nurses Global Assessment of Suicide Risk (NGASR) for the Portuguese population. In this study, a questionnaire was applied to a sample of 109 patients with depressive symptoms and risk factors for suicidal behaviors. The analysis of the results showed that most sample participants had a very high risk of suicide. The study of the psychometric properties of the NGASR showed moderate internal consistency and good content and criterion validity. Content validity, obtained through a panel of experts, was consensual. The NGASR index had good criterion validity, showing strong correlation with the SIQ, BDI and DASS-21 (R=0.830, p<0.05). The principal components analysis showed 6 factors, and the 15 predictive variables explained 66.92% of the total variance. These results are similar to those obtained in studies conducted in other countries and, therefore, the application of the NGASR is believed to be reliable for the Portuguese population.

    Full Text Available “Sustainable” is among the most sought after of all seafood product adjectives. Ironically it is also one of the most poorly defined and understood. The Global Aquaculture Performance Index (GAPI is the first tool to assess environmental performance of global marine aquaculture production, permitting direct comparison of disparate species, production methods and jurisdictions. Clear patterns emerge from this analysis; significant variation of environmental performance is driven by the species being farmed, significant room for improvement exists across the entire sector, the worst performing players are also the fastest growing, particularly within Asia, and perhaps most importantly, this work highlights the potential trap awaiting policy makers who focus too narrowly on farm production efficiency alone as a solution to diminishing seafood availability.

    The pollution of water bodies reduces their quality and is stressful to their biota. In a river, water usually is of the high-est quality in its headwaters reaches, becoming dirtier along its length as it passes through different land uses. Therefore, the aquatic environment should be assessed using physicochemical and biological features in order to provide a full spectrum of aquatic ecosystem health. Water Quality Indexes can be used to aggregate data on water quality parameters and to translate this information into a single value. The use of bio markers as indicators of toxicity delineates the effects of xenobiotics before the appearance of diseases in aquatic organism. The use of a battery bio markers may be useful to evaluate the various response to mixtures of pollutants. (Author)

    CO2, as the typical greenhouse gas causing the greenhouse effect, is a major global environmental problem and has attracted increasing attention from governments. Using algae to eliminate CO2, which has been proposed as an effective way to reduce the greenhouse effect in the past decades, can be disturbed by a growing number of artificial chemicals. Thus, seven types of chemicals and Selenastrum capricornutum (algae) were examined in this study, and the good consistency between the toxicity of artificial chemicals to algae and the disturbance of carbon fixation by the chemicals was revealed. This consistency showed that the disturbance of an increasing number of artificial chemicals to the carbon fixation of algae might be a "malware" worsening the global greenhouse effect. Therefore, this study proposes an original, promising index to assess the risk of deepening the greenhouse effect by artificial chemicals before they are produced and marketed.

    Full Text Available Growing environmental and socioeconomic concerns due to rapid urbanization, population growth and climate change impacts have motivated decision-makers to incorporate sustainable best practices for transportation infrastructure development and management. A “sustainable” transportation infrastructure implies that all the sustainability objectives (i.e., mobility, safety, resource efficiency, economy, ecological protection, environmental quality are adequately met during the infrastructure life cycle. State-of-the-art sustainability rating tools contain the best practices for the sustainability assessment of infrastructure projects. Generally, the existing rating tools are not well equipped to handle uncertainties associated with data limitations and expert opinion and cannot effectively adapt to site specific constraints for reliable sustainability assessment. This paper presents the development of a customizable tool, called “Green Proforma” for the sustainability assessment of roadway projects under uncertainties. For evaluating how well the project meets sustainability objectives, a hierarchical framework is used to develop the sustainability objective indices by aggregating the selected indicators with the help of fuzzy synthetic evaluation technique. These indices are further aggregated to attain an overall sustainability index for a roadway project. To facilitate the decision makers, a “Roadway Project Sustainometer” has been developed to illustrate how well the roadway project is meeting its sustainability objectives. By linking the sustainability objectives to measurable indicators, the “Green Proforma” paves the way for a practical approach in sustainable planning and management of roadway projects.

    This study sought consensus-based indices for quality assessment of the public health service (QAPHS) to evaluate the service quality of public health in Shenzhen and other cities in China. A qualitative study. A list of quality assessment indices was formed based on Donabedian theory. These indices were presented to an expert panel in a two-round Delphi study to establish a consensus view. A weight of indices was established to validate the applicability and practicability of the framework. The specialist authority coefficient and Kendall's W were also calculated based on statistical analysis. A total of 30 experts participated in the Delphi study. Consensus was reached on four first-grade indices, nine second-grade indices and 28 third-grade indices. The specialist authority coefficient (Cr) was high (between 0.88 and 0.92), while Kendall's coefficient (W) of all the indices was >0.5 with statistical significant differences (P < 0.05). This indicated correlation among panelists and had high reliability. A unified and hierarchical quality assessment index framework for public health services was established. The framework should be further tested and improved in practice. Copyright © 2014 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

    Our aim was to translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into Arabic and assess its validity and reliability for use among people in North Jordan. After translation into Arabic and back-translation to check the translation quality, a total of 288 participants completed the Arabic version of the GOHAI questionnaire. Individual GOHAI items were recoded and summed as originally recommended. The questionnaire sought information about socio-demographic characteristics and self-reported perception of general and oral health. Clinical examination included assessment of periodontal status, and number of decayed teeth, missing teeth, filled teeth and crowned teeth. Reliability, internal consistency, and concurrent, convergent and discriminant validity of GOHAI scores were examined. Mean GOHAI score was 40.9 (SD = 10.6, range: 12 to 60). Cronbach's alpha for the GOHAI score was 0.88, indicating a high degree of internal consistency and homogeneity between the GOHAI items. The test-retest correlation coefficient for add-GOHAI scores was 0.72, indicating good stability. Add-GOHAI scores increased with poorer perceived general and oral health. Convergent validity, construct validity and discriminant validity of the GOHAI were demonstrated. The Arabic translation of the GOHAI demonstrated acceptable validity and reliability when used for people in North Jordan. It could therefore be used as a valuable instrument for measuring oral health-related quality of life for people in this region.

    2017-01-01

    Full Text Available Transit accessibility is an important measure on the service performance of transit systems. To assess whether the public transit service is well accessible for trips of specific origins, destinations, and origin-destination (OD pairs, a novel measure, the Trip Coverage Index (TCI, is proposed in this paper. TCI considers both the transit trip coverage and spatial distribution of individual travel demands. Massive trips between cellular base stations are estimated by using over four-million mobile phone users. An easy-to-implement method is also developed to extract the transit information and driving routes for millions of requests. Then the trip coverage of each OD pair is calculated. For demonstrative purposes, TCI is applied to the transit network of Hangzhou, China. The results show that TCI represents the better transit trip coverage and provides a more powerful assessment tool of transit quality of service. Since the calculation is based on trips of all modes, but not only the transit trips, TCI offers an overall accessibility for the transit system performance. It enables decision makers to assess transit accessibility in a finer-grained manner on the individual trip level and can be well transformed to measure transit services of other cities.

    A proper soil risk assessment needs to estimate the processes that affect the fate and the behaviour of a contaminant, which are influenced by soil biotic and abiotic components. For this reason, the measurement of biomarkers in soil bioindicator organisms, such as earthworms, has recently received increasing attention. In this study, the earthworm Eisenia andrei was used to assess the pollutant-induced stress syndrome after exposure to sublethal concentrations of Cd (10 or 100 μg g(-1)) in OECD soil, after 14 d of exposure. Cadmium bioaccumulation and potential biomarkers such as catalase (CAT), hydrogen peroxide (H2O2), glutathione-S-transferase (GST), malondialdehyde (MDA), phenoloxidase (PO), metallothioneins (MTs) and genotoxic damage were determined. Results suggested that the exposure to 10 and 100 μg g(-1) Cd significantly increased Cd bioaccumulation, MTs and MDA; 100 μg g(-1) Cd contamination evidenced significantly higher values of H2O2 content and PO activity; CAT activity was inhibited at the higher concentration while GST and Comet assay did not show any significant differences from the control. Rank-based biomarker index showed that both different contaminated soils had an effect on the earthworms and allowed to validate the ecotoxicological relevance of this battery of biomarkers for a promising integrated multi-marker approach in soil monitoring and assessment.

    Full Text Available Rapid and non-destructive diagnostic tools to accurately assess crop nitrogen nutrition index (NNI are imperative for improving crop nitrogen (N diagnosis and sustaining crop production. This study was aimed to develop the relationships among NNI, leaf N gradient, chlorophyll meter (CM readings gradient, and positional differences chlorophyll meter index [PDCMI, the ratio of CM readings between different leaf layers (LLs of crop canopy] and to validate the accuracy and stability of these relationships across the different LLs, years, sites, and cultivars. Six multi-N rates (0–320 kg ha−1 field experiments were conducted with four summer maize cultivars (Zhengdan958, Denghai605, Xundan20, and Denghai661 at two different sites located in China. Six summer maize plants per plot were harvested at each sampling stage to assess NNI, leaf N concentration and CM readings of different LLs during the vegetative growth period. The results showed that the leaf N gradient, CM readings gradient and PDCMI of different LLs decreased, while the NNI values increased with increasing N supply. The leaf N gradient and CM readings gradient increased gradually from top to bottom of the canopy and CM readings of the bottom LL were more sensitive to changes in plant N concentration. The significantly positive relationship between NNI and CM readings of different LLs (LL1 to LL3 was observed, yet these relationships varied across the years. In contrast, the relationships between NNI and PDCMI of different LLs (LL1 to LL3 were significantly negative. The strongest relationship between PDCMI and NNI which was stable across the cultivars and years was observed for PDCMI1−3 (NNI = −5.74 × PDCMI1−3+1.5, R2 = 0.76**. Additionally, the models developed in this study were validated with the data acquired from two independent experiments to assess their accuracy of prediction. The root mean square error value of 0.1 indicated that the most accurate and robust

    The purpose of this study was to evaluate the degree of fatty infiltration (FI) of the pancreas using area-based assessment on computed tomography (CT) (CT area-based assessment) in its correlation and agreement/concordance with histopathology-based assessment. Furthermore, we examined whether CT area-based assessment was better than CT attenuation index-based assessment. We retrospectively evaluated the degree of FI of the pancreas in 37 pancreatic cancer patients who had undergone preoperative CT and pancreaticoduodenectomy. The degree of FI of the pancreas was examined by histopathology-based assessment using surgical resection samples, and CT area-based and CT attenuation index-based assessments. Mean values of pancreatic FI measured by area-based assessment on unenhanced CT and by histopathology-based assessments were 14.4 ± 23.2 % (range 0-77.7 %) and 16.2 ± 17.4 % (range 0.2-60.2 %), respectively. Area-based assessment on unenhanced CT showed higher correlation and concordance with histopathology-based assessment, demonstrating a Spearman correlation coefficient of 0.78 (P assessment, the corresponding values were -0.66 (P assessment is suggested to be better than CT attenuation index-based assessment.

    The Health Assessment Questionnaire (HAQ) is one of the most frequently used instruments to assess functional capacity in activities of daily living. The objective of our study was to determine the reproducibility and validity of an Argentinean version of the HAQ disability index (HAQ-DI) in patients with rheumatoid arthritis (RA). Consecutive adult patients with RA from 3 different provinces in Argentina were included. The original English version of the HAQ-DI was translated and adapted into Spanish by 3 rheumatologists and the final version back translated into English by a bilingual person. The reproducibility of the questionnaire was assessed in 30 patients who came for a second visit 3 to 5 days later. The cross-sectional construct validity was assessed by comparing the HAQ with classic parameters of disease activity (number of swollen and tender joints, patient and physician visual analog scale for pain and activity as well as functional class, erythrocyte sedimentation rate, and C-reactive protein. Two hundred patients with RA were included. The reproducibility was r = 0.97 (P = 1 x 10-5); intraitem correlation analysis did not show any redundancy. Correlation between HAQ-A and parameters of disease activity were all significant. A stepwise multiple regression analysis showed that the main variables associated with HAQ-A scores were visual analog scale for pain and duration of morning stiffness. A weak although significant negative correlation was found between the HAQ-A and economic level (r = -0.21, P = 0.03). The median time to complete the questionnaire was 5 minutes and there were no problems with any questions. This version of the HAQ-DI would allow for more availability so that Spanish-speaking countries can select the version most suitable to their sociocultural environment.

    Elderly subjects are considered a vulnerable group and they have more risk of nutritional problems. The risk of malnutrition increases in hospitalized geriatric patients. To compare the correlation between MNA and GNRI with anthropometric, biochemical and Barthel Index in hospitalized geriatric patients and to test the concordance between MNA and GNRI and between Mini Nutritional Assessment Short Form (MNA-SF) and MNA. It was a cross-sectional study on a sample of 40 hospitalized geriatric patients. For determination nutritional status we used MNA and GNRI; we evaluated the correlation between this both test with biochemical and anthropometric parameters and functional questionnaires. We used Pearson's simple correlation model, oneway ANOVA and multiple logistic regression to evaluate the relationship between MNA and GNRI. According to MNA, 17 patients (42.5%) were malnourished and according to GNRI, 13 patients (32.5%) had high risk of nutritional complications. The concordance of MNA and GNRI was 39% and between MNA-SF and MNA was 81%. The most significant differences were detected in weight, BMI, arm and calf circumference and weight loss parameters. Barthel index was significantly different in both tests. The MNA and GRNI had significant correlations with albumin, total protein, transferring, arm and calf circumference, weight loss and BMI parameters. In conclusion, it would be reasonable to use GRNI in cases where MNA is not applicable, or even use GRNI as a complement to MNA in hospitalized elderly patients. There is no reason why they should be deemed incompatible, and patients could benefit from more effective nutritional intervention.

    Few studies have applied the Chinese Diet Balance Index (DBI) in evaluating dietary quality for Chinese people. The present cross-sectional study assessed dietary quality based on DBI for older people, and the associated factors, in four socioeconomically distinct regions in China. The China Health and Nutrition Survey (CHNS) involves 2745 older Chinese people, aged 60 or over, from four regions (Northeast, East Coast, Central and West) in 2009. Dietary data were obtained by interviews using 24 hour-recall over three consecutive days. Four indicators: Total Score (TS), Lower Bound Score (LBS), Higher Bound Score (HBS) and Diet Quality Distance (DQD) from DBI were calculated for assessing dietary quality in different aspects. 68.9% of older people had different levels of excessive cereals intake. More than 50% of older people had moderate or severe surplus of oil (64.9%) and salt (58.6%). Intake of vegetables and fruit, milk and soybeans, water, and dietary variety were insufficient, especially for milk and soybeans. 80.8% of people had moderate or severe unbalanced diet consumption. The largest differences of DQD scores have been found for people with different education levels and urbanicity levels. People with higher education levels have lower DQD scores (polder Chinese people. Rectifying unbalanced diet intake may lead to prevention of non-communicable diseases (NCDs). Dieticians and health care professionals need to increase dissemination and uptake of nutrition education, with interventions targeted at regions of lower socioeconomic status.

    The umbilical cord is the only communication between the fetus and the placenta and, not surprisingly, lesions or conditions affecting it may have detrimental effects in both. One important feature of the umbilical cord is its coiling index (UCI), with hypo- and hypercoiling being associated with fetal thrombotic vasculopathy, intolerance of labor, intrauterine growth restriction, cord stricture, thrombosis of cord and chorionic blood vessels, and fetal demise. It is essential that every placenta report include the UCI. The UCI could also be assessed prenatally, but there is currently no way of accurately assessing the entire length of the umbilical cord. The aim of this study was to compare UCI measured in a segment of cord 10 cm long (UCI-10) and over its total length (UCI-T). One hundred fifty consecutive placenta reports in which both measurements were recorded were retrieved from the files and analyzed. Gestational age ranged from 16 to 42 weeks, with a mean of 33.67 ± 5.96 weeks and a median of 36 weeks. Mean UCI-10 was 0.4360 ± 0.2625 coils/cm and mean UCI-T was 0.3530 ± 0.2022 coils/cm; the difference between these measurements was highly statistically significant (P UCI-T by 23.5%; it can be concluded, therefore, that the latter should be used.

    The lack of appropriate methodologies and indicators to quantify three-dimensional (3-D) building constructions poses challenges to authorities and urban planners when formulating polices to reduce health risks due to heat stress. This study evaluated the applicability of an innovative three-dimensional Urbanization Index (3DUI), based on remote sensing database, with a 5 m spatial resolution of 3-D man-made constructions to representing intra-urban variability of air temperature by assessing correlation of 3DUI with air temperature from a 3-D perspective. The results showed robust high correlation coefficients, ranging from 0.83 to 0.85, obtained within the 1,000 m circular buffer around weather stations regardless of season, year, or spatial location. Our findings demonstrated not only the strength of 3DUI in representing intra-urban air-temperature variability, but also its great potential for heat stress assessment within cities. In view of the maximum correlation between building volumes within the 1,000 m circular buffer and ambient air temperature, urban planning should consider setting ceilings for man-made construction volume in each 2 × 2 km(2) residential community for thermal environment regulation, especially in Asian metropolis with high population density in city centers.

    To investigate psychosocial characteristics and problems of a representative sample of Swedish drunk drivers with special consideration of the gender of the driver; analyze criminal records of the drivers before and after enrollment in the study; identify psychosocial predictors of relapse to drunk driving. Psychosocial characteristics were assessed by the Addiction Severity Index (ASI). Alcohol problems were additionally assessed by the Alcohol Use Disorders Identification Test (AUDIT). Criminal records were collected for the five year period before the enrollment, and for the subsequent two years, from Sweden's official crime statistics. About half of the investigated drivers had other psychosocial problems besides the drink driving offence. Female drivers had more alcohol, drug, psychiatric and relational problems, including with parents when growing up, than male drivers, but less previous and subsequent criminality. Heavily drunk drivers (blood alcohol concentration > or = 0.1%) had more problems with alcohol, legal status and employment and support than the other drunk drivers. Problems with legal status, family and social relations and alcohol use increased the risk of relapse in drunk driving, while medical problems seemed to be a protective factor. Different ASI risk factors were identified for relapse in either traffic offences or other crimes. As well as the drunk driving offence, drunk drivers often have other psychosocial problems, female drivers in particular. Already the blood alcohol concentration per se gives some indication of the psychosocial problem profile of a drunk driver and the ASI profile has some prognostic value for relapse in drunk driving.

    The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following extensive validation of accessible models of human thermoregulation, the advanced multi-node 'Fiala' model was selected to form the basis of UTCI. This model was coupled with an adaptive clothing model which considers clothing habits by the general urban population and behavioral changes in clothing insulation related to actual environmental temperature. UTCI was developed conceptually as an equivalent temperature. Thus, for any combination of air temperature, wind, radiation, and humidity, UTCI is defined as the air temperature in the reference condition which would elicit the same dynamic response of the physiological model. This review analyses the sensitivity of UTCI to humidity and radiation in the heat and to wind in the cold and compares the results with observational studies and internationally standardized assessment procedures. The capabilities, restrictions and potential future extensions of UTCI are discussed.

The results showed robust high correlation coefficients, ranging from 0.83 to 0.85, obtained within the 1,000 m circular buffer around weather stations regardless of season, year, or spatial location. Our findings demonstrated not only the strength of 3DUI in representing intra-urban air-temperature variability, but also its great potential for heat stress assessment within cities. In view of the maximum correlation between building volumes within the 1,000 m circular buffer and ambient air temperature, urban planning should consider setting ceilings for man-made construction volume in each 2 × 2 km2 residential community for thermal environment regulation, especially in Asian metropolis with high population density in city centers.

    A major goal of ecotoxicology is the prediction of adverse outcomes for populations from sensitive and early physiological responses. A snapshot of the physiological state of an organism can be provided by metabolic fingerprints. However, to inform chemical risk assessment, multivariate metabolic fingerprints need to be converted to readable end points suitable for effect estimation and comparison. The concentration- and time-dependent responsiveness of metabolic fingerprints to the PS-II inhibitor isoproturon was investigated by use of a Myriophyllum spicatum bioassay. Hydrophilic and lipophilic leaf extracts were analyzed with gas chromatography-mass spectrometry (GC-MS) and preprocessed with XCMS. Metabolic changes were aggregated in the quantitative metabolic effect level index (MELI), allowing effect estimation from Hill-based concentration-response models. Hereby, the most sensitive response on the concentration scale was revealed by the hydrophilic MELI, followed by photosynthetic efficiency and, 1 order of magnitude higher, by the lipophilic MELI and shoot length change. In the hydrophilic MELI, 50% change compares to 30% inhibition of photosynthetic efficiency and 10% inhibition of dry weight change, indicating effect development on different response levels. In conclusion, aggregated metabolic fingerprints provide quantitative estimates and span a broad response spectrum, potentially valuable for establishing adverse outcome pathways of chemicals in environmental risk assessment.

    All families face normative transitions. Some are perceived as stressful and calls for family resources to maintain or restore family well-being. In times of illness, families also need to develop strengths and capabilities to enhance family well-being. The way these are developed is related to family hardiness. Family hardiness is thus seen as a family resource, and the Family Hardiness Index (FHI) was developed to measure family stress resistance and adaptation resources. The index was not available in Swedish and no extensive international psychometric evaluation was found. Therefore, the aim was to translate and validate the Swedish version of the FHI. The study was approved by a Regional Ethical Review Board. Data from 174 Swedish participants, family members to persons with cognitive dysfunctions (n = 95) and nursing students (n = 79) were included. Family members were enrolled in outpatient clinics in primary care and rehabilitation, and nursing students at a nursing school. Psychometric properties were evaluated through calculations of missing data, distributions of item and scale scores, item correlations, Cronbach's alpha, confirmatory factor analyses and correlations with theoretically related constructs. Sample scores had acceptable data quality, internal consistency for the FHI total scale was satisfactory (α = 0.86), and construct validity was supported. Our findings cast some doubt on the intended interpretation since confirmatory factor analyses showed that a modified four-subscale version, excluding one subscale, showed best fit. The Control subscale lacked important psychometric properties in terms of homogeneity, internal consistency and construct validity. The sample size was probably sufficiently large for the factor analyses, but the subgroup analyses should be treated with caution. The conclusion is that the Swedish version of the FHI is a promising scale for assessing family hardiness, but more solid evidence for the factor structure in

    Characterization of soil hydraulic properties is important for assessing soil water regime in agricultural fields. In the laboratory, measurements of soil hydrodynamic properties are costly and time consuming. Numerous studies recently demonstrated that reflectance spectroscopy can give a rapid estimation of several soil properties including those related with soil water content. The main objective of this research study was to show that near infrared spectroscopy (NIRS) is a useful tool to study the combined effect of soil tillage and fertilizer input on soil hydrodynamic properties. The study was carried out on soil samples collected from an experimental station located in Brittany, France. In 2000, the field was designed in a split-plot combining three tillage practices and four sources of fertilizers (mineral and organic). Undisturbed soil blocks were sampled in 2012 from three different depths of topsoil (0-7 cm, 7-15 cm and 15-20 cm) at each treatment. From each soil block, four aggregates with 3-4 cm diameter by 5-6 cm height were collected. Soil aggregates were first saturated and were then drained through 10 matric potential, from saturation up to permanent wilting point (pF=4.2), by successively using a suction table and a pressure chamber. Once the desired water pressure head was reached, soil samples were scanned to acquire reflectance spectra between 400-2500 nm using a handheld spectroradiometer equipped with a contact probe. Each spectrum was transformed into continuum removal, and an index based on the full width at half maximum (FWHM) of the absorption feature around 1920 nm was calculated. This index showed a linear relationship (R2>0.9) with volumetric water content. Moreover our results showed that the slope of the line was well correlated with the range of treatment. Overall, our findings indicate that the absorption feature of continuum removal spectra around 1900 nm can be useful to study the effect, particularly, of tillage on hydrodynamic

    Lake Taihu Basin, one of the most developed regions in China, has received considerable attention due to its severe pollution. Our study provides a clear understanding of the water quality in the rivers of Lake Taihu Basin based on basin-scale monitoring and a water quality index (WQI) method. From September 2014 to January 2016, four samplings across four seasons were conducted at 96 sites along main rivers. Fifteen parameters, including water temperature, pH, dissolved oxygen (DO), conductivity, turbidity (tur), permanganate index (CODMn), total nitrogen, total phosphorus, ammonium (NH4-N), nitrite, nitrate (NO3-N), calcium, magnesium, chloride, and sulfate, were measured to calculate the WQI. The average WQI value during our study period was 59.33; consequently, the water quality was considered as generally "moderate". Significant differences in WQI values were detected among the 6 river systems, with better water quality in the Tiaoxi and Nanhe systems. The water quality presented distinct seasonal variation, with the highest WQI values in autumn, followed by spring and summer, and the lowest values in winter. The minimum WQI (WQImin), which was developed based on a stepwise linear regression analysis, consisted of five parameters: NH4-N, CODMn, NO3-N, DO, and tur. The model exhibited excellent performance in representing the water quality in Lake Taihu Basin, especially when weights were fully considered. Our results are beneficial for water quality management and could be used for rapid and low-cost water quality evaluation in Lake Taihu Basin. Additionally, we suggest that weights of environmental parameters should be fully considered in water quality assessments when using the WQImin method. Copyright © 2017 Elsevier B.V.

    Full Text Available Integrated water resource management (IWRM is facing great challenges due to growing uncertainties caused by climate change (CC, rapid socio-economic and technological changes, and population growth. In the present study, we have developed different indices to assess the availability of water using an IWRM approach. These indices evaluate supply to demands, surface availability, groundwater availability, reservoirs, and environmental flow. Moreover, reliability, resilience, and vulnerability were determined. Sustainability index (SI and sustainability index by groups (SG were determined based on the five indices (all indices vary from 0 to 1. The impacts of climate change affect surface and groundwater availability, as do the agricultural, urban, and industrial requirements on the different supplies. We used the generalized AQUATOOL Decision Support System Shell (DSSS to evaluate the IWRM in the Rio Grande Basin (Morelia, México. Various emission scenarios from representative concentration pathways (RCPs were applied to the basin for the years 2015–2039 and 2075–2099. The results indicate increases in agricultural and urban demand, and decreases in surface runoff, as well as groundwater recharge. The proposed indices are useful for different approaches (decision-makers, water policy, and drought risks, among others. CC significantly affects the different proposed indices and indicates a decrease of the SI, SG1, and SG2 (i.e., less availability. For example, we found that SG2 decreased from 0.812 to 0.195 under the RCP 8.5 2075–2099 scenario, and SG2 equal to 0.252 and 0.326 for the RCP 6.0 2075–2099 and RCP 4.5 2070–2099 scenarios, respectively (values close to 0 indicate worst drought conditions.

    Full Text Available On the basis of the vulnerability-led approach, the Prevalent Community-level Vulnerability Index (PCVI was developed as a simple composite index used to represent community-level vulnerability to climate change in the socioeconomic and hazard contexts. The PCVI consists of three major components which are Exposure & hazard, Socioeconomic-ecological fragility and Coping capacity. All of these components are further comprised of different indicators, representing different aspects of biophysical and social vulnerability of grass-root communities. Based on the results analyzed in the provincial pilot sites, the PCVI could represent both spatial patterns and magnitudes of vulnerability of each community in consistence with the local economic-social-environmental contexts. It generally reflects the differences in the local contexts and factors that determine overall vulnerability of each community. For the ease in calculating the PCVI especially for the provincial operating staffs and general public, the PREvalent Community Climate Change Vulnerability Tool (RECCC was further developed as a user-friendly, Excel-based program. In conclusions, the outputs of this study that include the PCVI and its database as well as the RECCC program are useful not only for analyzing vulnerability and assessing risks of community to climate change, but also for supporting decision-making process in developing and implementing adaptation activities at provincial level. These outputs were also designed for further integrating as a supplementary part of Provincial�s Decision Supporting System (DSS, with the purpose of promoting the participation of local organizations and stakeholders in coping with the adverse impacts of climate change. However, additional development of ERCCC program, together with dissemination of the vulnerability framework as well as the use of ERCCC program to local organizations needs to be continued.

    Full Text Available The aim of this work is to assess the groundwater quality in Pengyang County based on an improved water quality index. An information entropy method was introduced to assign weight to each parameter. For calculating WQI and assess the groundwater quality, total 74 groundwater samples were collected and all these samples subjected to comprehensive physicochemical analysis. Each of the groundwater samples was analyzed for 26 parameters and for computing WQI 14 parameters were chosen including chloride, sulphate, pH, chemical oxygen demand (COD, total dissolved solid (TDS, total hardness (TH, nitrate, ammonia nitrogen, fluoride, total iron (Tfe, arsenic, iodine, aluminum, nitrite, metasilicic acid and free carbon dioxide. At last a zoning map of different water quality was drawn. Information entropy weight makes WQI perfect and makes the assessment results more reasonable. The WQI for 74 samples ranges from 12.40 to 205.24 and over 90% of the samples are below 100. The excellent quality water area covers nearly 90% of the whole region. The high value of WQI has been found to be closely related with the high values of TDS, fluoride, sulphate, nitrite and TH. In the medium quality water area and poor quality water area, groundwater needs some degree of pretreated before consumption. From the groundwater conservation view of point, the groundwater still need protection and long term monitoring in case of future rapid industrial development. At the same time, preventive actions on the agricultural non point pollution sources in the plain area are also need to be in consideration.

    The aim of the study was to translate and validate the oral health-related quality of life assessment tool named Geriatric Oral Health Assessment Index (GOHAI) into Hindi language for use in the Indian population. The 12-item GOHAI questionnaire was translated into Hindi, back-translated and compared with the original English version. After pilot testing and appropriate changes, the Hindi version was administered to a group of 500 patients visiting the geriatric medicine clinic in All India Institute of Medical Sciences, New Delhi. The questionnaire was re-administered to 29 participants after a gap of minimum 7 days. The measures for reliability and validity were also assessed. Cronbach's α score (0.79) showed excellent internal consistency. Item-scale correlations varied from 0.06 to 0.75. Test-retest correlation on the 29 patients showed excellent results (ranging from 0.748 to 0.946). Lower GOHAI scores were associated with patient's self-perception of nutritional status, perceptive need for prosthesis, number of posterior occluding pair of teeth. Higher GOHAI scores were seen with patients with removable prosthesis than with edentulous or partially edentulous participants. Age group was also found to be a significant factor for GOHAI scores. The Hindi version of GOHAI exhibits acceptable validity and reliability and can be used in the elderly Indian population as a measure of oral health-related quality of life. © 2013 John Wiley & Sons A/S and The Gerodontology Society.

    The detection of leaf functionality is of pivotal importance for plant scientists from both theoretical and practical point of view. Leaves are the sources of dry matter and food, and they sequester CO2 as well. Under the perspective of climate change and primary resource scarcity (i.e. water, fertilizers and soil), assessing leaf photo-assimilation in a rapid but comprehensive way can be helpful for understanding plant behavior under different environmental conditions and for managing the agricultural practices properly. Several approaches have been proposed for this goal, however, some of them resulted very efficient but little reliable. On the other hand, the high reliability and exhaustive information of some models used for estimating net photosynthesis are at the expense of time and ease of measurement. The present study employs a multivariate statistical approach to assess a model aiming at estimating leaf photo-assimilation performance, using few and easy-to-measure variables. The model, parameterized for apple and pear and subjected to internal and external cross validation, involves chlorophyll fluorescence, carboxylative activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCo), air and leaf temperature. Results prove that this is a fair-predictive model allowing reliable variable assessment. The dependent variable, called IPL index, was found strongly and linearly correlated to net photosynthesis. IPL and the model behind it seem to be (1) reliable, (2) easy and fast to measure and (3) usable in vivo and in the field for such cases where high amount of data is required (e.g. precision agriculture and phenotyping studies). © 2015 Scandinavian Plant Physiology Society.

    Awareness of their medical prognosis enables terminally ill patients to make decisions on treatments and end-of-life care/planning, and to reach acceptance. Yet, many patients receiving palliative care (PC) are unaware of their prognosis, even when death is imminent and has been discussed with health care providers. A better understanding of patient characteristics associated with prognostic awareness (PA) is needed to develop interventions aimed at improving it. To identify patient characteristics associated with PA in a PC population. The sample comprised 2090 palliative home care patients in Ontario, Canada, assessed using the interRAI Palliative Care Assessment. Independent variables included sociodemographic, cognitive/physical functioning, mood, psychological well-being, and social support. Using cross-sectional data, an adjusted logistic regression model was developed to identify key patient characteristics associated with PA. A multifaceted definition of PA was assumed and represented dichotomously in the model. Multiple imputation was used to address missing data, generating results similar to the complete case analysis. The PA was higher in patients with: a shorter prognosis (odds ratio [OR] 2.90, 95% confidence interval [CI] 1.93-4.33), increased hours of informal care (OR 1.71, 95% CI 1.15-2.52), less cognitive impairment (OR 1.61, 95% CI 1.14-2.28), and in patients at peace with life (OR 1.79, 95% CI 1.27-2.53). Site differences were observed but do not reflect differences in age, gender, prognosis, or diagnosis. Some patient characteristics are amenable to clinical intervention to raise PA, such as being at peace, cognitive impairment, and depression. Prognostic communications vary in timing and quality and may underlie our site differences, but further research is required to confirm this. Crown Copyright © 2015. Published by Elsevier Inc.

    Development organisations need easy-to-use and quick-to-implement indicators to quantify poverty when requested to measure program impact. In this paper we assess the validity of the Progress out of Poverty Index (PPI)™, a country-specific indicator based on ten closed questions on directly observable household characteristics, by its compliance to the SMART criteria. Each response receives a pre-determined score, such that the sum of these scores can be converted into the likelihood the household is living below the poverty line. We focus on the PPI scorecard for Rwanda, which was validated using two national household surveys conducted in 2005/06 and 2010/11. The PPI is Specific, Measurable, Available cost effectively, and Timely available. Yet, its Relevance depends on the way it is used. Although it accurately distinguishes poor from non-poor households, making it a useful reporting tool, its limited sensitivity to changes in poverty status restricts its usefulness for evaluating the impact of development projects.

    2015-07-01

    The present investigation is aimed at understanding the hydrogeochemical parameters and development of a water quality index (WQI) to assess groundwater quality of a rural tract in the northwest of Bardhaman district of West Bengal, India. Groundwater occurs at shallow depths with the maximum flow moving southeast during pre-monsoon season and south in post-monsoon period. The physicochemical analysis of groundwater samples shows the major ions in the order of HCO3>Ca>Na>Mg>Cl>SO4 and HCO3>Ca>Mg>Na>Cl>SO4 in pre- and post-monsoon periods, respectively. The groundwater quality is safe for drinking, barring the elevated iron content in certain areas. Based on WQI values, groundwater falls into one of three categories: excellent water, good water, and poor water. The high value of WQI is because of elevated concentration of iron and chloride. The majority of the area is occupied by good water in pre-monsoon and poor water in post-monsoon period.

    The purpose of this study was to examine body mass index (BMI) of college freshmen and compare with BMI in senior or graduate year of school. A convenience sample was drawn from health records of students at a small private university in the northeast United States. BMIs were calculated for those students who had an admission physical examination with documented height and weight and a subsequent physical examination in senior or graduate year. Descriptive statistics and a paired t-test were performed. No significant difference was determined statistically between admission BMI and BMI in later years. The rate of overweight and obese students rose from 25.6% to 32% in the time interval between freshman and senior or graduate year. Those students who entered college with BMIs considered to be overweight or obese generally were still overweight or obese in the later college years in this population. Nurse practitioners in college health and in private practice who assess traditional college-age young adults are in a position to provide education about healthy eating habits, weight loss strategies, and community resources as well as to monitor weights and provide support. ©2014 The Author(s) ©2014 American Association of Nurse Practitioners.

    Musical skills and expertise vary greatly in Western societies. Individuals can differ in their repertoire of musical behaviours as well as in the level of skill they display for any single musical behaviour. The types of musical behaviours we refer to here are broad, ranging from performance on an instrument and listening expertise, to the ability to employ music in functional settings or to communicate about music. In this paper, we first describe the concept of ‘musical sophistication’ which can be used to describe the multi-faceted nature of musical expertise. Next, we develop a novel measurement instrument, the Goldsmiths Musical Sophistication Index (Gold-MSI) to assess self-reported musical skills and behaviours on multiple dimensions in the general population using a large Internet sample (n = 147,636). Thirdly, we report results from several lab studies, demonstrating that the Gold-MSI possesses good psychometric properties, and that self-reported musical sophistication is associated with performance on two listening tasks. Finally, we identify occupation, occupational status, age, gender, and wealth as the main socio-demographic factors associated with musical sophistication. Results are discussed in terms of theoretical accounts of implicit and statistical music learning and with regard to social conditions of sophisticated musical engagement. PMID:24586929

    Early childhood caries (ECC) is a multifactorial disease resulting mainly from a time-specific interaction of micro-organisms with sugars on a tooth surface. The purpose of this study was to assess the relationship of dietary intake, as measured by the Healthy Eating Index-2005 (HEI-2005) to ECC. Cross-sectional analytical study. Sixty preschool children were equally divided into three groups according to their caries experience [Group 1: caries-free children, group 2: children with ECC, group 3: children with severe early childhood caries (S-ECC)]. The decayed (non-cavitated or cavitated), missing (due to caries) and filled tooth surfaces (dmfs) score was determined through visual dental examination for each child. Questionnaires were collected recording the demographic characteristics of the families as well as 24-h food recall forms capturing the dietary intake of the children during the previous day. Accordingly, the HEI-2005 score was calculated for each child. The caries experience of the children in this study was significantly associated with their age. Caries-free children showed significantly higher 'Whole fruit', 'Milk', 'Sodium' and total HEI-2005 scores. The study findings illustrate the prominent protective role played by healthful dietary practices against dental caries in preschool children. © 2014 BSPD, IAPD and John Wiley & Sons A/S.

    Atopic dermatitis (AD) is a chronic inflammatory skin disorder with an immunologic basis. It may have negative medical and social impacts on a patient and his family. To assess serum level of vitamin D among children with AD and determine its association with AD severity using the AD Scoring System Index. A case-control study. Twenty-nine patients with AD in the age group between 2 and 12 years were enrolled in the study. The severity of the disease was determined by the AD scoring system. Thirty controls were recruited. Serum levels of 25-hydroxyvitamin D3 [25(OH)D3] were tested using commercial automated chemiluminescent microparticle immunoassay. The mean value of vitamin D in children with AD was much lower than normal value, and there was a significant difference in the mean values of vitamin D between children with AD (5.4±1.9 ng/mL) and the controls (28.9±2.4 ng/mL). Serum 25(OH)D levels were found to be significantly higher in mild AD (14.6±3.5 ng/mL) compared with moderate (5.5±3.1 ng/mL) or severe AD (0.3±0.1 ng/mL); P<0.001. Patients with AD have lower serum vitamin D levels than normal. Vitamin D deficiency might be related to the severity of AD.

    The Analgesia Nociception Index (ANI), based on heart rate (HR) variability analysis, is known to decrease after a painful stimulus during surgery under general anesthesia in adults. It is measured continuously and noninvasively. We studied ANI response to procedural pain in a pediatric population and ANI measurement's feasibility in this context, across age. A prospective, noninterventional pilot study was performed. All children (between 6 mo and under 18 y) undergoing muscle biopsy conducted under analgesia and light sedation were included. Medical staff was blind to the ANI monitor. HR and ANI were recorded and analyzed during 2 periods: T1 before incision and T2 after incision. Pain was assessed by the FLACC scale at T2. We observed ANI and HR variations after incision. ANI, HR, and FLACC were compared between children younger or older than 6 years. Enrollment or technical issues were reported. A total of 26 children were included (median age, 6 y; ranging from 6 mo to 16 y; 16 male). ANI decreased from T1 to T2. HR, ANI, or FLACC values were not different in children younger or older than 6 years. No parents or children refused to take part in the study. No technical issues was reported. In this pilot study, ANI measurement seems relevant in pediatric procedural pain, across age. Further studies are needed to confirm these results.

    Full Text Available Tourism is a very important industry, and it is deeply affected by climate. This article focuses on the role of climate in tourism seasonality and attempts to assess the impacts of climate resources on China’s tourism seasonality by using the Tourism Climate Index (TCI. Seasonal distribution maps of TCI scores indicate that the climates of most regions in China are comfortable for tourists during spring and autumn, while the climate conditions differ greatly in summer and winter, with “excellent”, “good”, “acceptable” and “unfavorable” existing almost by a latitudinal gradation. The number of good months throughout China varies from zero (the Tibetan Plateau area to 10 (Yunnan Province, and most localities have five to eight good months. Moreover, all locations in China can be classified as winter peak, summer peak and bi-modal shoulder peak. The results will provide some useful information for tourist destinations, travel agencies, tourism authorities and tourists.

    Musical skills and expertise vary greatly in Western societies. Individuals can differ in their repertoire of musical behaviours as well as in the level of skill they display for any single musical behaviour. The types of musical behaviours we refer to here are broad, ranging from performance on an instrument and listening expertise, to the ability to employ music in functional settings or to communicate about music. In this paper, we first describe the concept of 'musical sophistication' which can be used to describe the multi-faceted nature of musical expertise. Next, we develop a novel measurement instrument, the Goldsmiths Musical Sophistication Index (Gold-MSI) to assess self-reported musical skills and behaviours on multiple dimensions in the general population using a large Internet sample (n = 147,636). Thirdly, we report results from several lab studies, demonstrating that the Gold-MSI possesses good psychometric properties, and that self-reported musical sophistication is associated with performance on two listening tasks. Finally, we identify occupation, occupational status, age, gender, and wealth as the main socio-demographic factors associated with musical sophistication. Results are discussed in terms of theoretical accounts of implicit and statistical music learning and with regard to social conditions of sophisticated musical engagement.

    Full Text Available Bangladesh is one of the vulnerable countries of the world for natural disasters. Drought is one of the common and severe calamities in Bangladesh that causes immense suffering to people in various ways. The present research has been carried out to examine the frequency of meteorological droughts in Bangladesh using the long-term rainfall data of 30 meteorological observatories covering the period of 1948–2011. The study uses the highly effective Standardized Precipitation Index (SPI for drought assessment in Bangladesh. By assessing the meteorological droughts and the history of meteorological droughts of Bangladesh, the spatial distributions of meteorological drought indices were also analysed. The spatial and temporal changes in meteorological drought and changes in different years based on different SPI month intervals were analysed. The results indicate that droughts were a normal and recurrent feature and it occurred more or less all over the country in virtually all climatic regions of the country. As meteorological drought depends on only rainfall received in an area, anomaly of rainfall is the main cause of drought. Bangladesh experienced drought in the years 1950, 1951, 1953, 1954, 1957, 1958, 1960, 1961, 1962, 1963, 1965, 1966, 1967 and 1971 before independence and after independence Bangladesh has experienced droughts in the years 1972, 1973, 1975, 1979, 1980, 1983, 1985, 1992, 1994, 1995, 2002, 2004, 2006, 2009 and 2011 during the period 1948–2011. The study indicated that Rajshahi and its surroundings, in the northern regions and Jessore and its surroundings areas, the island Bhola and surrounding regions, in the south-west region, were vulnerable. In the Sylhet division, except Srimongal, the areas were not vulnerable but the eastern southern sides of the districts Chittagong, Rangamati, Khagrachhari, Bandarban and Teknaf were vulnerable. In the central regions, the districts of Mymensingh and Faridpur were more vulnerable

    Collisions between aircraft and birds, birdstrikes, pose a serious threat to aviation safety. The occurrence of these events is influenced by land-uses in the surroundings of airports. Airports located in the same region might have different trends for birdstrike risk, due to differences in the surrounding habitats. Here we developed a quantitative tool that assesses the risk of birdstrike based on the habitats within a 13-km buffer from the airport. For this purpose, we developed Generalized Linear Models (GLMs) with binomial distribution to estimate the contribution of habitats to wildlife use of the study area, depending on season. These GLMs predictions were combined to the flight altitude of birds within the 13-km buffer, the airport traffic pattern and the severity indices associated with impacts. Our approach was developed at Venice Marco Polo International airport (VCE), located in northeast Italy and then tested at Treviso Antonio Canova International airport (TSF), which is 20 km inland. Results from the two airports revealed that both the surrounding habitats and the season had a significant influence to the pattern of risk. With regard to VCE, agricultural fields, wetlands and urban areas contributed most to the presence of birds in the study area. Furthermore, the key role of distance of land-uses from the airport on the probability of presence of birds was highlighted. The reliability of developed risk index was demonstrated since at VCE it was significantly correlated with bird strike rate. This study emphasizes the importance of the territory near airports and the wildlife use of its habitats, as factors in need of consideration for birdstrike risk assessment procedures. Information on the contribution of habitats in attracting birds, depending on season, can be used by airport managers and local authorities to plan specific interventions in the study area in order to lower the risk.

    Flocculant modified soils/clays are being increasingly studied as geo-engineering materials for lake restoration and harmful algal bloom control. However, the potential impacts of adding these materials in aquatic ecological systems remain unclear. This study investigated the potential effects of chitosan, cationic starch, chitosan modified soils (MS-C) and cationic starch modified soils (MS-S) on the aquatic organisms by using a bioassay battery. The toxicity potential of these four flocculants was quantitatively assessed using an integrated biotic toxicity index (BTI). The test system includes four aquatic species, namely Chlorella vulgaris, Daphnia magna, Cyprinus carpio and Limnodrilus hoffmeisteri, which represent four trophic levels in the freshwater ecosystem. Results showed that median effect concentrations (EC50) of the MS-C and MS-S were 31-124 times higher than chitosan and cationic starch, respectively. D. magna was the most sensitive species to the four flocculants. Histological examination of C. carpio showed that significant pathological changes were found in gills. Different from chitosan and cationic starch, MS-C and MS-S significantly alleviated the acute toxicities of chitosan and cationic starch. The toxicity order of the four flocculants based on BTI were cationic starch > chitosan > MS-S > MS-C. The results suggested that BTI can be used as a quantitative and comparable indicator to assess biotic toxicity for aquatic geo-engineering materials. Chitosan or cationic starch modified soil/clay materials can be used at their optimal dosage without causing substantial adverse effects to the bioassay battery in aquatic ecosystem.

    Full Text Available Groundwater vulnerability assessment was carried out at Igbara Oke Southwestern Nigeria, with a view to classify the area into vulnerability zones, by applying the electrical resistivity method, using Schlumberger electrode arrays with maximum electrode separation (AB/2 of 65 m in (41 different locations for data acquisition. Geoelectric parameters (layer resistivity and thickness were determined from the interpreted data. The study area comprises four geoelectric layers (topsoil, lateritic layer, weathered/fractured layer and fresh basement. The geoelectric parameters of the overlying layers across the area were used to assess the vulnerability of the underlying aquifers to near-surface contaminants with the aid of vulnerability maps generated. Three models were compared by maps using geo-electrically derived models; longitudinal conductance, GOD (groundwater occurrence, overlying lithology and depth to the aquifer and GLSI (geoelectric layer susceptibility indexing. The total longitudinal conductance map shows the north central part of the study area as a weakly protected (0.1–0.19 area, while the northern and southern parts have poor protective capacity (<0.1; this is in agreement with the GOD method which shows the northern part of the study area as less vulnerable (0–0.1 while the southern part has low/moderate (0.1–0.3 vulnerability to contamination. The longitudinal conductance exaggerates the degree of susceptibility to contamination than the GOD and GLSI models. From the models, vulnerability to contamination can be considered higher at the southern part than the northern part and therefore, sources of contamination like septic tank, refuse dump should be cited far from groundwater development area. Keywords: Aquifer vulnerability, Longitudinal conductance, GOD and GLSI

    The objectives of this study were to assess the energy flow, greenhouse gas (GHG) emission, global warming potential (GWP) and sustainability of corn production systems in Kermanshah province, western Iran. The data were collected from 70 corn agroecosystems which were selected based on randomly sampled method in the summer of 2011. The results indicated that total input and output energy were 50,485 and 134,946 MJ ha{sup −1}, respectively. The highest share of total input energy in corn production systems was recorded for N fertilizer, electricity power and diesel fuel with 35, 25 and 20%, respectively. Energy use efficiency and energy productivity were 2.67 and 0.18 kg MJ{sup −1}, respectively. Also agrochemical energy ratio was estimated as 40%. Applying chemical inputs produced the following emissions of greenhouse gases: 2994.66 kg CO{sub 2,} 31.58 kg N{sub 2}O and 3.82 kg CH{sub 4} per hectare{sub .} Hence, total GWP was 12,864.84 kg Co{sub 2}eq ha{sup −1} in corn production systems. In terms of CO{sub 2} equivalents 23% of the GWPs came from CO{sub 2}, 76% from N{sub 2}O, and 1% from CH{sub 4}.

    Cocoa agroecosystems are a major land-use type in the tropical rainforest belt of West Africa, reportedly associated with several ecological changes, including soil degradation. This study aims to develop a composite soil degradation assessment index (CSDI) for determining the degradation level of cocoa soils under smallholder agroecosystems of southwestern Nigeria. Plots where natural forests have been converted to cocoa agroecosystems of ages 1-10, 11-40, and 41-80 years, respectively representing young cocoa plantations (YCPs), mature cocoa plantations (MCPs), and senescent cocoa plantations (SCPs), were identified to represent the biological cycle of the cocoa tree. Soil samples were collected at a depth of 0 to 20 cm in each plot and analysed in terms of their physical, chemical, and biological properties. Factor analysis of soil data revealed four major interacting soil degradation processes: decline in soil nutrients, loss of soil organic matter, increase in soil acidity, and the breakdown of soil textural characteristics over time. These processes were represented by eight soil properties (extractable zinc, silt, soil organic matter (SOM), cation exchange capacity (CEC), available phosphorus, total porosity, pH, and clay content). These soil properties were subjected to forward stepwise discriminant analysis (STEPDA), and the result showed that four soil properties (extractable zinc, cation exchange capacity, SOM, and clay content) are the most useful in separating the studied soils into YCP, MCP, and SCP. In this way, we have sufficiently eliminated redundancy in the final selection of soil degradation indicators. Based on these four soil parameters, a CSDI was developed and used to classify selected cocoa soils into three different classes of degradation. The results revealed that 65 % of the selected cocoa farms are moderately degraded, while 18 % have a high degradation status. The numerical value of the CSDI as an objective index of soil degradation

    The aim of this study was to evaluate the effectiveness of multidimensional ergonomic intervention (MEI) model to reduce musculoskeletal discomfort (MSD) among street sweepers. A quasi-experimental study was conducted in Chiang Rai Province. The MEI model was designed on the basis of four core components: cognitive behavior therapy, ergonomic education training, stretching exercise, and the foam sleeve broom handle grip. Seventy-five street sweepers volunteered for the screening process on MSD of having level score ≥4 by physiotherapist. Face to face interviews were used mainly in order to diagnose MSD. Physical examination was performed by physiotherapist and physical performance by sports scientist. The findings showed that the MEI model among the intervention group significantly reduced MSD compared with that among control group at exit model and follow-up (P<0.01). This research suggests that the MEI model was appropriate to reduce MSD associated with repetitive movement and awkward postures on task.

    Full Text Available Background: Breast cancer affects over one million women annually and is the most common global malignancy among women. Extensive improvements have taken place in the management of breast cancer in recent years and a higher percentage of women are cured from this disease. A proper assessment of the quality of life of women with breast cancer is an essential component in disease management. The Functional Assessment of Cancer Therapy- Breast Symptom Index has been commonly used and well-validated among English speaking populations as well as other populations. To date, no formal translation and evaluation of the Functional Assessment of Cancer Therapy-Breast System Index exists in Arabic. Therefore, this study intends to translate, adapt and face-validate the Functional Assessment of Cancer Therapy-Breast System Index into Arabic, specifically in the context of the Lebanese culture. Methods: We conducted forward and backward translation in Arabic, combined with face validity by clinicians. This was followed by pre-testing to ensure the instrument’s adequacy and cultural sensitivity conducted by the administration of face-to-face interviews with individual breast cancer patients (n=33 and two focus groups (4 women/group to evaluate the relevance and appropriateness of each item and words used in the questionnaire. Results: Study results reinforced the value of the Arabic translated version of the Functional Assessment of Cancer Therapy-Breast System Index in capturing the quality of life of women with breast cancer in Lebanon. Conclusion: The instrument was perceived to be adequate, appropriate for use, culturally sensitive, simple as well as exhaustive. Suggestions have been made to enrich the instruments’ ability to incorporate other quality of life dimensions not captured, as well to enhance the cultural specificity of the Functional Assessment of Cancer Therapy-Breast System Index, when administered among Lebanese women diagnosed with

    Full Text Available Objective: Using radioactive iodine (RAI as the first line therapy for Graves’ hyperthyroidism and as the treatment of choice for relapsed Graves’ disease is increasing in recent times. However, there has been little consensus on the most appropriate dose to use. So this study is to determine the response of hyperthyroidism to fixed doses of 370 MBq and 555 MBq RAI therapies and determine the incidence of hypothyroidism at 6 months post therapy. Methods: Hyperthyroid patients’ case records treated with radioiodine was retrospectively reviewed to determine the response rate of hyperthyroidism to the two fixed dose regimens. Statistical analysis was done with SPSS version 15.0 and the level of statistical significance was taken as p<0.05. Forty subjects, 6 males (15% and 34 females (85% received RAI therapy for Graves’ hyperthyroidism, mean age was 49.4 years (range, 25-75years. The thyroid function status at 6 months post therapy was available for all subjects. 24 patients (60% received 370 MBq while 16 patients (40% received 555 MBq. Results: The response for fixed doses of 370 MBq and 555 MBq were similar (100%. Also, the incidence of hypothyroidism in these subjects which was 66.6% with fixed dose of 370 MBq and 62.5% with fixed dose of 555 MBq within 6 months post RAI therapy were similar. Conclusion: SRAI is highly effective for the treatment of hyperthyroidism, with a cure rate of 100%. However, it has proved impossible to determine a fixed dose regimen for individual patients accurately to guarantee an euthyroid state. This is because hypothyroidism is a natural predictable sequel of RAI therapy.

    The objectives of this study were to assess the energy flow, greenhouse gas (GHG) emission, global warming potential (GWP) and sustainability of corn production systems in Kermanshah province, western Iran. The data were collected from 70 corn agroecosystems which were selected based on randomly sampled method in the summer of 2011. The results indicated that total input and output energy were 50,485 and 134,946 MJ ha(-1), respectively. The highest share of total input energy in corn production systems was recorded for N fertilizer, electricity power and diesel fuel with 35, 25 and 20%, respectively. Energy use efficiency and energy productivity were 2.67 and 0.18 kg MJ(-1), respectively. Also agrochemical energy ratio was estimated as 40%. Applying chemical inputs produced the following emissions of greenhouse gases: 2994.66 kg CO2, 31.58 kg N2O and 3.82 kg CH4 per hectare. Hence, total GWP was 12,864.84 kg Co2eq ha(-1) in corn production systems. In terms of CO2 equivalents 23% of the GWPs came from CO2, 76% from N2O, and 1% from CH4. In this study input and output C equivalents per total GHG and Biomass production were 3508.59 and 10,696.34 kg Cha(-1). Net carbon and sustainability indexes in corn production systems were 7187.75 kg Cha(-1) and 2.05. Accordingly, efficient use of energy is essential to reduce the greenhouse gas emissions and environmental impact in corn agroecosystems. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available This paper investigated the wind energy potential by analysing a certain amount of gathered 10-min measured data at four stations located at coastal sites in Malaysia, i.e., Kudat, Mersing, Kijal, and Langkawi. The wind data are collected from a total of four new wind measurement masts with sensors mounted at various heights on the tower. The measured data have enabled the establishment of wind resource maps and the power law indexes (PLIs analysis. In addition, the dependence of PLI upon surface temperature and terrain types is studied, as they are associated to the form of exponential fits. Moreover, the accuracy of exponential fits is assessed by comparing the results with the 1/7 law via the capacity factor (CF discrepancies. In order to do so, the wind turbine with a hub-height similar to the maximum height of the measured data at each site is selected to simulate energy production. Accordingly, the discrepancy of CF based on the extrapolated data by employing 1/7 laws and exponential fits, in spite of being computed using measured data, is determined as well. Furthermore, the large discrepancy of the wind data and the CF, which has been determined with the application of 1/7, is compared to the exponential fits. This is because; discrepancy in estimation of vertical wind speed could lead to inaccurate CF computation. Meanwhile, from the energy potential analysis based on the computed CF, only Kudat and Mersing display a promising potential to develop a medium capacity of wind turbine power, while the other sites may be suitable for wind turbines at a small scale.

    Full Text Available OBJECTIVE: To assess and compare the respiratory muscle strength among eutrophic, overweight and obese school children, as well as to identify anthropometric and respiratory variables related to the results.METHODS: Cross-sectional survey with healthy schoolchildren aged 7-9 years old, divided into three groups: Normal weight, Overweight and Obese. The International Study of Asthma and Allergies in Childhood (ISAAC questionnaire was applied. The body mass index (BMI was evaluated, as well as the forced expiratory volume in one second (FEV1 with a portable digital device. The maximal inspiratory and expiratory pressures (MIP and MEP were measured by a digital manometer. Comparisons between the groups were made by Kruskal-Wallis test. Spearman's correlation coefficient was used to analyze the correlations among the variables.RESULTS: MIP of eutrophic school children was higher than MIP found in overweight (p=0.043 and obese (p=0.013 children. MIP was correlated with BMI percentile and weight classification (r=-0.214 and r=-0.256 and MEP was correlated with height (r=0.328. Both pressures showed strong correlation with each other in all analyses (r≥0.773, and less correlation with FEV1 (MIP - r=0.362 and MEP - r=0.494. FEV1 correlated with MEP in all groups (r: 0.429 - 0.569 and with MIP in Obese Group (r=0.565. Age was correlated with FEV1 (r=0.578, MIP (r=0.281 and MEP (r=0.328.CONCLUSIONS: Overweight and obese children showed lower MIP values, compared to eutrophic ones. The findings point to the influence of anthropometric variables on respiratory muscle strength in children.

    Full Text Available Context: Caries epidemiological studies based on clinical examination alone tend to underestimate proximal caries. Aims: This study aims to determine the additional value of radiographic examination (bitewings compared to clinical examination in assessing posterior proximal caries. It also aims to determine the radiographic multiplication /adjusting / correction factors by which a clinical decayed surface (D-S and decayed-missing-filled surfaces (DMFS score could be multiplied, to obtain an actual D-S and DMFS score Materials and Methods: Two groups of 100 subjects each, in the age range of 16-20 years, were examined clinically for caries and their DMFS index recorded. Both groups were subjected to bitewing radiographs to detect the clinically undiagnosed posterior proximal caries. The radiographic adjusting factors were determined for group A. To check its repeatability and thus its usefulness, radiographic correction factor was determined for Group B. Statistical Analysis: The results were statistically analyzed with the use of means, standard deviations, regression equation and "Z" test. Level of significance was determined at P > 0.05. Results: A significant number of clinically undetected proximal caries was diagnosed with the help of bitewing radiographs. The difference between the radiographic adjusting/correction factor for D-S and DMFS score for the two groups was statistically not significant (P > 0.05 thus verifying the repeatability of the radiographic correction factors. Conclusion: The radiographic correction factors can be used to obtain a more precise estimate of true caries prevalence in a particular study population without having to subject all individuals to radiographic examination.

    Full Text Available Background : Rivers are a fraction of flowing waters in the worlds and one of the important sources of water for different consumptions such as agricultural, drinking and industrial uses. The aim of this study was to assess water quality of the Khorramrood River in Khorramabad by NSFWQI index. Materials and Methods: In this cross-sectional study, quality parameters needed for NASWQI index calculation such as BOD5, dissolved oxygen (DO, total nitrate, fecal coliform, pH, total phosphate, temperature, turbidity and total suspended solids content were measured for six months (from July to December 2012using standard methods at six selected stations. The river zoning conducted by GIS software. Results: According to the results obtained through this study, the highest and the lowest water quality value was observed in stations 1 and 6 with NSFWQI indexes 82 water with good quality, 42 water with bad quality, respectively. With moving toward last station (from 1 to 6 station water pollution increased. Conclusion: Results of the study indicated that water quality index NSFWQI is a good index to identify the effect of polluter sources on the river water. Based on the average of the index NSFWQI, water quality in station one was good, in the second, third and fourth stations were mediocre and the fifth and sixth stations had bad quality. These results allow to make decisions about monitoring and controlling water pollution sources, as well as provide different efficient uses of it by relevant authorities.

    Full Text Available Introduction: Overweight and obesity are recognized mortality risk factors in the general population. The aim of the study was to analyse the phenotypic distribution of body mass index (BMI, and to identify the prevalence of malnutrition and clinical and nutritional factors related to BMI in autonomous institutionalized elders. Material and Methods: Cross-sectional and descriptive study in 104 institutionalized aged people (73% female, mean of age 86.4 [±6.2] years and time on institutionalization 25.7 [±21.7] months. Mini-Nutritional Assessment (MNA, anthropometric measures and laboratory parameters were used for nutritional assessment. Bioimpedance analysis (BIA-101; RJL-System was used for body composition analysis. The sample was classified into BMI tertiles (Tn: T1=<26.2kg/m2; T2=26.3-29.7kg/m2; and T3=≥29.8kg/m2. Results: The phenotypic distribution of BMI was: overweight 51% and, prevalence of obesity 29.8%. Mean of BMI: 28.3 (±4.6 kg/m2. Nutritional risk or malnutrition were 60.6% and 11.5%, respectively in the sample. The tertiles of BMI showed significant differences with: mid-arm muscle circumference, triceps-skinfold thickness, total body water (TBW (all, p<0.001. Subjects into T1 had significantly higher nutritional risk or malnutrition compared with T2 and T3 counterparts (p=0.015. Waist-circumference, calf-circumference (at least, p<0.01, and TBW (p<0.001 were independent predictors of BMI in the linear regression analysis (R2=0.52. Conclusions: Overweight and obesity measured by BMI is not an exclusion criterion of malnutrition in the geriatric population. Nutritional screening by MNA and the conjoint use of clinical-nutritional parameters are useful for identifying at nutritional risk or malnutrition. Further studies are needed to define the potential nutritional risk factors associated with BMI in autonomous institutionalized aged.

    Glycemic index and/or glycemic load have been explored as an alternative for the prevention and/or management of obesity, cardiovascular disease, type 2 diabetes mellitus, and cancer. The purpose of the manuscript is to describe the design and methods used in the GLYNDIET Project, a study designed to simultaneously address the questions related to the exactly role of low glycaemic index carbohydrates has on weight loss. This study was designed as a 6-months randomized, parallel, controlled clinical trial aiming to evaluate the effect of the dietary glycemic index on weightloss, satiety, glucose and insulin metabolism, lipid profile, inflammation and other emergent metabolic risk markers. Eligible subjects were community-dwelling men and women aged between 30 and 60 years, with a body mass index between 27 and 35 kg/m2. Subjects were randomly assigned to three different dietary intervention groups (low glycemic index diet, high glycemic index diet or low-fat diet), that were isocaloric, and did not differ in the amount of dietary fibre. Monthly, study subjects were scheduled for control visits where anthropometry, blood pressure, dietary habits, satiety and physical activity were assessed. Blood, urine and subcutaneous adipose tissue samples were collected at baseline and at the end of the study to further molecular and biochemical measurements. The GLYNDIET study was designed to determine if there is a greater effectiveness of a carbohydrate restricted diet with low glycemic index compared to an isocaloric diet with carbohydrates of high glycemic index or low-fat diet on weight loss in middle long-term.

    2004-02-01

    In support of a national need to improve the current state-of-the-art in alerting decision makers to the risk of terrorist attack, a quantitative approach employing scientific and engineering concepts to develop a threat-risk index was undertaken at the Idaho National Engineering and Environmental Laboratory (INEEL). As a result of this effort, a set of models has been successfully integrated into a single comprehensive model known as Quantitative Threat-Risk Index Model (QTRIM), with the capability of computing a quantitative threat-risk index on a system level, as well as for the major components of the system. Such a threat-risk index could provide a quantitative variant or basis for either prioritizing security upgrades or updating the current qualitative national color-coded terrorist threat alert.

    The traditional National Healthcare Safety Network (previously National Nosocomial Infections Surveillance) risk index is used to predict the risk of surgical site infection across many operative procedures. However, this index may be too simple to predict risk in the various procedures performed in colorectal surgery. The aim of this study was to evaluate the usefulness of the risk index by analyzing the impact of the risk index factors on surgical site infection after abdominal colorectal surgery. Using our surgical site infection surveillance database, we analyzed retrospectively 538 consecutive patients who underwent abdominal colorectal surgery between 2005 and 2010. Correlations between surgical site infection and the following risk index factors were analyzed: length of operation, American Society of Anesthesiologists score, wound classification, and use of laparoscopy. The 75th percentile for length of operation was determined separately for open and laparoscopic surgery in the study model. Univariate analyses showed that surgical site infection was more strongly associated with a >75th percentile length of operation in the study model (odds ratio [OR], 2.07) than in the traditional risk index model (OR, 1.64). Multivariable analysis found that surgical site infection was independently associated with a >75th percentile length of operation in the study model (OR, 2.75; 95% confidence interval [CI], 1.66-4.55), American Society of Anesthesiologists score ≥3 (OR, 2.22; 95% CI, 1.10-4.34), wound classification ≥III (OR, 5.29; 95% CI, 2.62-10.69), and open surgery (OR, 2.21; 95% CI, 1.07-5.17). Performance of the risk index category was improved in the study model compared with the traditional model. The risk index category is sufficiently useful for predicting the risk of surgical site infection after abdominal colorectal surgery. However, the 75th percentile length of operation should be set separately for open and laparoscopic surgery.

    Satellite derived normalized difference (ND) vegetation index data, based on urban and rural region composed of a variety of land surface environments, are evaluated. These data are linearly related to the difference in observed urban and rural minimum temperatures. It is concluded that the difference in the ND index between urban and rural regions reflects the difference in the surface properties (evaporation and heat storage capacity) of these two environments and urban and rural minimum temperatures (the urban heat island effect).

    The Rac/Rop GTPase OsRac1 plays an essential role in rice immunity. However, the regulatory genes acting downstream of OsRac1 are largely unknown. We focused on the RAI1 gene, which is up-regulated in suspension cells expressing a constitutively active form of OsRac1. RAI1 encodes a putative basic helix-loop-helix transcription factor. A microarray analysis of cells transformed with an inducible RAI1 construct showed increased expression of PAL1 and OsWRKY19 genes after induction, suggesting that these genes are regulated by RAI1. This was confirmed using RAI1 T-DNA activation-tagged and RNA interference lines. The PAL1 and OsWRKY19 genes were also up-regulated by sphingolipid and chitin elicitors, and the RAI1 activation-tagged plants had increased resistance to a rice blast fungus. These results indicated that RAI1 is involved in defense responses in rice. RAI1 interacted with OsMAPK3 and OsMAPK6 proteins in vivo and in vitro. Also, RAI1 was phosphorylated by OsMAPK3/6 and OsMKK4-dd in vitro. Overexpression of OsMAPK6 and/or OsMAPK3 together with OsMKK4-dd increased PAL1 and OsWRKY19 expression in rice protoplasts. Therefore, the regulation of PAL1 and OsWRKY19 expression by RAI1 could be controlled via an OsMKK4-OsMAPK3/6 cascade. Co-immunoprecipitation assays indicated that OsMAPK3 and OsRac1 occur in the same complex as OsMAPK6. Taken together, our results indicate that RAI1 could be regulated by OsRac1 through an OsMAPK3/6 cascade. In this study, we have identified RAI1 as the first transcription factor acting downstream of OsRac1. This work will help us to understand the immune system regulated by OsRac1 in rice and its orthologs in other plant species.

    Comparative assessment of pollution by metals (Pb, Cu, Cd, Fe, and As) was performed for the first time for the bays and inlets of the Murmansk coast of the Barents Sea; the international Metal Pollution Index (MPI) was applied for the fucoids. The background pollution was assessed for each studied element by MPI in the fucoids taking into account the seawater salinity. It was found that the MPI index calculated for fucoids might be recommended for the qualitative assessment of the metal pollution level with regard to the water salinity for both the studied sampling sites and the natural environment. The comparative monitoring of Pb, Cu, Cd, Fe, and As concentrations in the bays and inlets of the Murmansk coast of the Barents Sea using MPI evidenced that Pechenga Inlet was the most polluted area; Korabel'naya Inlet was the least polluted, which reflected the existing level of the anthropogenic load.

    The European Heavy Metals in Mosses Surveys (UNECE-ICP Vegetation) is a programme performed every 5 years since 1990 in at least 21 European countries. The moss surveys aim at uncovering the spatiotemporal patterns of metal and nitrogen bioaccumulation in mosses. In France, the moss survey was conducted for the third time in 2006. Five hundred thirty-six monitoring sites were sampled across the whole French territory. The aim of the presented study is to give an integrative picture of the metal bioaccumulation for the entire French territory without geographical gaps. Furthermore, confounding factors of the metal bioaccumulation in mosses should be investigated. Element loads of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), mercury (Hg), nickel (Ni), lead (Pb), antimony (Sb), vanadium (V) and zinc (Zn) measured in the French campaign 2006 were aggregated to a multi-metal index (MMI). This index was first introduced in the German moss surveys and represents the mean rank of each monitoring site or estimated raster cell regarding all elements referred to. Hence, the spatial variability of the metal bioaccumulation in France could be assessed as a whole. A comparison of the MMI map with the spatial patterns of the Cu loads in mosses was then drawn, as Cu originates to a large extent from urban sources. Applying CHAID, the MMI and the Cu loads in the mosses were further investigated with regard to confounding factors. The said results were discussed on the basis of recent scientific publications. The MMI surface map shows high values in strongly industrialized and urbanized regions as well as at sites of high altitude, lying, for example in the Massif Central and the French Alps. Accordingly, the CHAID decision tree consequently shows the altitude to be the statistically most significant influencing factor of the MMI followed by the sampled moss species. As for the MMI map, the surface map for Cu mirrors urban agglomerations, as high values can be

    Noise may be defined as any unwanted sound. Sound becomes noise when it is too loud, unexpected, uncontrolled, happens at the wrong time, contains unwanted pure tones or unpleasant. In addition to being annoying, loud noise can cause hearing loss, and, depending on other factors, can affect stress level, sleep patterns and heart rate. The primary object for determining subjective estimations of loudness is to present sounds to a sample of listeners under controlled conditions. In heating, ventilation and air conditioning (HVAC) systems only the ventilation fan industry (e.g., bathroom exhaust and sidewall propeller fans) uses loudness ratings. In order to find satisfaction, percent of exposure to noise is the valuable issue for the personnel who are working in these areas. The room criterion (RC) method has been defined by ANSI standard S12.2, which is based on measured levels of in HVAC systems noise in spaces and is used primarily as a diagnostic tool. The RC method consists of a family of criteria curves and a rating procedure. RC measures background noise in the building over the frequency range of 16-4000 Hz. This rating system requires determination of the mid-frequency average level and determining the perceived balance between high-frequency (HF) sound and low-frequency (LF) sound. The arithmetic average of the sound levels in the 500, 1000 and 2000 Hz octave bands is 44.6 dB; therefore, the RC 45 curve is selected as the reference for spectrum quality evaluation. The spectral deviation factors in the LF, medium-frequency sound and HF regions are 2.9, 7.5 and -2.3, respectively, giving a Quality Assessment Index (QAI) of 9.8. This concludes the QAI is useful in estimating an occupant's probable reaction when the system design does not produce optimum sound quality. Thus, a QAI between 5 and 10 dB represents a marginal situation in which acceptance by an occupant is questionable. However, when sound pressure levels in the 16 or 31.5 Hz octave bands exceed 65

    Full Text Available Aim: Uttarakhand is a relatively new state and many cross bred cattle were introduced to boost the milk yield of the state. Despite all efforts the milk yield of dairy in Uttarakhand is comparatively low. In our study, we assessed the effect of heat stress on milk production, using thermal humidity index (THI in high (cross bred cattle and low milk producing (LMP cows (native cows in Dehradun district of Uttarakhand, India. Materials and Methods: Effect of heat stress was measured on high and LMP cross bred cows using THI maintained on standard feeding and nutritional value. Daily ambient temperature and relative humidity were recorded to calculate the THI. Daily milk production was noted to verify the effect of heat stress. Furthermore, profile the thyroid hormones using enzyme-linked immunosorbent assay. Results: Low yielding cows did not show any significant change when the THI was above 72 from month June to October during stress condition. But high yielding cows shows a significant decrease (p<0.05 in milk yield when THI was above 80 (severe stress zone in the month of June to October and milk production decrease from an average of 18±1.4 to 10.9±0.92 L whereas in November-December when THI declines in the zone of comfort the milk yield did not show significant rise. The thyroid hormones (T3 and T4 level were found lower in summer heat stress condition for a high yielding cattle. Conclusion: Summer heat stress significantly decreased milk yield in high milk producing (HMP crossbred cows. As THI rises from comfort zone to stress zone milk yield decreased by 30-40% and this loss in milk production is irreversible. Management strategies should be needed as environmental control housing is suggested for the HMP crossbred cattle to minimize the heat stress. If all the dairies with cross bred cattle implement these small modifications in housing of cattle, there would be a huge increase in milk production.

    Purpose: Within a multicenter study (DUE-01) focused on the search of predictors of erectile dysfunction and urinary toxicity after radiotherapy for prostate cancer, a dummy run exercise on penile bulb (PB) contouring on computed tomography (CT) images was carried out. The aim of this study was to quantitatively assess interobserver contouring variability by the application of the generalized DICE index. Methods and Materials: Fifteen physicians from different Institutes drew the PB on CT images of 10 patients. The spread of DICE values was used to objectively select those observers who significantly disagreed with the others. The analyses were performed with a dedicated module in the VODCA software package. Results: DICE values were found to significantly change among observers and patients. The mean DICE value was 0.67, ranging between 0.43 and 0.80. The statistics of DICE coefficients identified 4 of 15 observers who systematically showed a value below the average (p value range, 0.013 - 0.059): Mean DICE values were 0.62 for the 4 'bad' observers compared to 0.69 of the 11 'good' observers. For all bad observers, the main cause of the disagreement was identified. Average DICE values were significantly worse from the average in 2 of 10 patients (0.60 vs. 0.70, p < 0.05) because of the limited visibility of the PB. Excluding the bad observers and the 'bad' patients,' the mean DICE value increased from 0.67 to 0.70; interobserver variability, expressed in terms of standard deviation of DICE spread, was also reduced. Conclusions: The obtained values of DICE around 0.7 shows an acceptable agreement, considered the small dimension of the PB. Additional strategies to improve this agreement are under consideration and include an additional tutorial of the so-called bad observers with a recontouring procedure, or the recontouring by a single observer of the PB for all patients included in the DUE-01 study.

Engorged ticks from each strain were collected monthly from February 2002 to February 2004. These were weighed and kept in the laboratory until egg-laying. Oogenic masses were individually weighed and incubated until larvae emergence. REI and RAI were calculated from each sample, grouping ticks by weight in 100 mg range classes. An analysis of variance and Duncan's multiple rank tests were carried out on the data (P < 0.05). Pearson's correlation coefficients were estimated (P < 0.01) in order to determine the relationship between engorgement weight and the weight and number of laid and hatched eggs. The Native strain showed a higher engorgement weight than Media Joya strain. In both strains REI and RAI were similar in all weight classes; with a quadratic tendency in Media Joya and linear-quadratic in the Native strain (P < 0.05). Significant differences where observed when REI and RAI of both strains were compared along the duration of the study (P < 0.01) with the Native strain performing better in both indexes, including better performance during the dry season. All parameters studied showed highly significant correlation; eggs laid and eggs hatched were notably highly correlated, 0.94 and 0.91, for Media Joya strain and Native strain respectively.

    Full Text Available (Received: 2014/10/27 - Accepted: 2014/12/15This work evaluated the business risk change of 20 companies included on the sustainable index of the Mexican Stock Exchange (BMV. The unlevered beta coefficient was used for this analysis. Two periods were compared: the one before, and the one after including the companies on the index. For each of the 20 companies it was used financial information, stocks closing prices and the stock market index value, over a period of 234 weeks. Then, considering the two periods, the statistical difference between the unlevered beta coefficient averages was calculated. Finally, a hypothesis proof was made to evaluate the business risk change. It was found that for 12 out of the 20 companies, the unlevered beta coefficient suffered a reduction. The findings suggest that it is not enough for the companies to certify as sustainable in order to reduce its business risk.

    In general, Synthetic Indexes of sustainability have been applied to specific countries and regions. With some variations, the ones considered simple, such as the case of the Ecological Footprint (EF), have been applied to port areas. The same has not happened with those of a multidimensional nature (Global Synthetics) that still have a minimal and partial presence in the analysis of port sustainability. Understanding that this type of index represents an interesting and novel avenue of research applied to port systems, this contribution analyses and ranks a sample of 16 Spanish Port Authorities that group 23 ports of general interest using a Global Synthetic Index of Sustainability (developed using the four dimensions of sustainable development: economic, institutional, environmental and social).

  13. The ecofunctional quality index (EQI): a new tool for assessing lagoonal ecosystem impairment

    Science.gov (United States)

    Fano, E. A.; Mistri, M.; Rossi, R.

    2003-03-01

    A multimetric index for the evaluation of environmental quality (the ecofunctional quality index, EQI) has been developed using biotic data from three Italian coastal lagoons. Sampling programs were conducted between 1998 and 2000, on a yearly basis, with seasonal frequency at diverse sites in each lagoon. The rationale of the index is that certain attributes, selected on the basis of established principles of benthic ecology, are fundamental for lagoon ecosystem function. The chosen attributes were primary productivity, expressed as phytoplankton, seaweed and seagrass biomasses; structure and productivity of the benthic community, expressed as numerical abundance, biomass density, number of species, and taxonomic diversity of macrozoobenthos; and finally, trophic complexity, expressed as macrozoobenthic functional diversity. The EQI is constituted by the sum of weights given to these eight attributes, each transformed onto a dimensionless 0-100 quality scale. In this way, the use of EQI can derive a series of values yielding a 'functional classification' of sites within a lagoon or between different lagoons. The proposed index is a low cost, flexible and robust routine indicator of lagoon ecosystem impairment and could be of particular benefit to environmental managers and policymakers who require tools capable of expressing the degree of degradation or environmental quality of different lagoon habitats. The process of developing and the initial testing of EQI reported in this paper is intended as preliminary, and until validation of this index is accomplished by incorporating data from a wider range of lagoon environments, we caution the use of this index in anything other than an exploratory manner.

    Diabetes mellitus is a chronic degenerative disease characterized by elevated hyperglycemia, triggering a series of processes and culminating in chronic, uncontrolled, cellular and vascular damage in different organs. To assess whether the elevated glycosylated hemoglobin, microalbuminuria, and the time evolution of more than 10 years of diabetes mellitus are associated with elevated resistance index of the interlobar renal arteries assessed with pulsed Doppler in patients with metabolic uncontrolled diabetes mellitus. Transversal-analytical, observational, prospective study that included diabetic patients attending UMAE abdominal ultrasound in 25 of IMSS, from October 15, 2014 to November 15, 2014, which was performed for pulsed Doppler index resistance of vascular interlobar renal arteries and was collected from electronic medical records: age, sex, glycated hemoglobin, and microalbuminuria. The association between metabolic uncontrolled diabetes mellitus was analyzed with the elevation of resistance index by χ(2) test or Fisher, being significant with a value of p < 0.05, and to assess the magnitude of the association that was measured with a response magnitude of 95%. 63 patients with type 2 diabetes were examined, with an average age of 52.3 ± 14.2 years, 41 were older than 50 years (65.0%), 26 with hypertension (41.2%), 32 with higher levels of glycated hemoglobin 7 (50.8%), 35 with normoalbuminuria (55.6%), 28 with microalbuminuria (44.4%), and 39 with a time evolution of diabetes of more than 10 years (61.9%). We observed a statistically significant difference between microalbuminuria and increased duration of diabetes mellitus with high resistance index. The alterations in renal microvasculature conditioned by the occurrence of microalbuminuria in diabetic nephropathy and the duration of diabetes are strongly associated with higher resistance index.

    2011-07-01

    This paper briefly recapitulates the Frank-Starling law of the heart, reviews approaches to establishing diastolic and systolic force-length behaviour in intact isolated cardiomyocytes, and introduces a dimensionless index called 'Frank-Starling Gain', calculated as the ratio of slopes of end-systolic and end-diastolic force-length relations. The benefits and limitations of this index are illustrated on the example of regional differences in Guinea pig intact ventricular cardiomyocyte mechanics. Potential applicability of the Frank-Starling Gain for the comparison of cell contractility changes upon stretch will be discussed in the context of intra- and inter-individual variability of cardiomyocyte properties.

  16. A Hazard Assessment and Proposed Risk Index for Art, Architecture, Archive and Artifact Protection: Case Studies for Assorted International Museums

    Science.gov (United States)

    Kirk, Clara J.

    This study proposes a hazard/risk index for environmental, technological, and social hazards that may threaten a museum or other place of cultural storage and accession. This index can be utilized and implemented to measure the risk at the locations of these storage facilities in relationship to their geologic, geographic, environmental, and social settings. A model case study of the 1966 flood of the Arno River and its impact on the city of Florence and the Uffizi Gallery was used as the index focus. From this focus an additional eleven museums and their related risk were assessed. Each index addressed a diverse range of hazards based on past frequency and magnitude. It was found that locations nearest a hazard had exceptionally high levels of risk, however more distant locations could have influences that would increase their risk to levels similar to those locations near the hazard. Locations not normally associated with a given natural hazard can be susceptible should the right conditions be met and this research identified, complied and assessed those factions found to influence natural hazard risk at these research sites.

    Hyperspectral images possess properties such as rich spectral information, narrow bandwidth, and large numbers of bands. Finding effective methods to retrieve land features from an image by using similarity assessment indices with specific spectral characteristics is an important research question. This paper reports a novel hyperspectral image similarity assessment index based on spectral curve patterns and a reflection-absorption index. First, some spectral reflection-absorption features are extracted to restrict the subsequent curve simplification. Then, the improved Douglas-Peucker algorithm is employed to simplify all spectral curves without setting the thresholds. Finally, the simplified curves with the feature points are matched, and the similarities among the spectral curves are calculated using the matched points. The Airborne Visible Infrared Imaging Spectrometer (AVIRIS) and Reflective Optics System Imaging Spectrometer (ROSIS) hyperspectral image datasets are then selected to test the effect of the proposed index. The practical experiments indicate that the proposed index can achieve higher precision and fewer points than the traditional spectral information divergence and spectral angle match.

    The ExTra index, produced by the French Scientific Center for Building Physics, evaluates ambient concentrations of transport-related pollutants in front of the work and living places of urban dwellers. This study contributes to the validation of the ExTra index by carrying out measurements in four French cities. It compares nitrogen oxide concentrations (NOx) measured over 6 weeks with passive samplers, and NOx calculated concentrations using the ExTra index. The study takes into account traffic density, topographical parameters (building height, road, and pavement width), weather conditions (wind direction and strength), and background pollution levels. The model was tested at 100 street canyons sites. There were highly significant correlations (0.90 in Grenoble, 0.95 in Nice, 0.89 in Paris, and 0.89 in Toulouse) and good intraclass correlation coefficients (0.75 in Grenoble, 0.91 in Nice, 0.89 in Paris, and 0.86 in Toulouse) between the two series of values. These results suggest that if the ExTra index were to be applied to all the different residences and workplaces of a subject throughout his (her) life, it could be a useful epidemiological tool for studying the long-term health effects of transport-related emissions and for reconstructing individual exposure to such pollution in order to avoid misclassification.

    Fibromyalgia (FM) is a generalized chronic pain condition that is often accompanied by symptoms such as fatigue, sleep disturbances, psychological and cognitive alterations, headache, migraine, variable bowel habits, diffuse abdominal pain, and urinary frequency. Its key assessment domains include pain, fatigue, disturbed sleep, physical and emotional functioning, and patient global satisfaction and health-related quality of life (HRQL). A number of evaluation measures have been adapted from the fields of rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis, and others such as the Fibromyalgia Assessment Status (FAS) index and the Fibromyalgia Impact Questionnaire (FIQ) have been specifically developed. The aim of this study was to assess the impact of FM on HRQL by comparing the performance of the FAS index, the FIQ and the Health Assessment Questionnaire [HAQ] in 541 female and 31 male FM patients (mean age 50 years; mean disease duration 7.7 years) entered in the database of a web-based survey registry developed by the Italian Fibromyalgia Network (IFINET). Tests of convergent validity showed that the FAS index and FIQ significantly correlated with each other (rho=0.608, pindex and other clinical measures of disability, including the HAQ (rho=0.423, pindex revealed a statistically significant difference between males and females (p=0.048), analysed using the Mann-Whitney U-test for all pair wise comparisons. The FAS index is a valid three-item instrument (pain, fatigue and sleep disturbances) that performs at least as well as the FIQ in FM patients, and is simpler to administer and score. Both questionnaires may be useful when screening FM patients, with the choice of the most appropriate instrument depending on the setting.

    The Multidimensional Geriatric Assessment (MGA) is currently used for assessing geriatric oncological patients, but a new prognostic index - the Multidimensional Prognostic Index (MPI) - has a demonstrated prognostic value in cancer patients too. The present work was designed to compare the MPI and MGA as predictors of 12-month mortality. 160 patients ≥70 years old with locally-advanced or metastatic solid cancers consecutively joining our Geriatric Oncology Program were administered a Comprehensive Geriatric Assessment to calculate their MGA and MPI scores. Geriatric Clinic, Geriatric Surgery Clinic, Medical Oncology Unit, Padova Hospital, Italy. Using Cohen's Kappa coefficient, there was a poor concordance between the MPI and MGA. Severe MPI being associated with a higher mortality risk than Frail in the MGA. The ROC curves indicated that the MPI had a greater discriminatory power for 12-month mortality than the MGA. In our population of elderly cancer patients, the MPI performed better than the MGA in predicting mortality. Further evidence from larger prospective trials is needed to establish whether other geriatric scales, such as the GDS and CIRS-SI, could enhance the value of prognostic indexes applied to elderly cancer patients. © 2016 John Wiley & Sons Ltd.

    The literature shows that an increased body mass index (BMI) may be a potential risk factor for periodontitis. Association between BMI and periodontitis has been ascribed to unhealthy dietary patterns with insufficient micronutrients and excess sugar and fat content. The present study intended to assess the relation between BMI and periodontal status among state government employees in Shimla city, Himachal Pradesh in India. The study sample comprised 1,008 subjects aged 18-58 years, drawn by a proportional sample from 10,908 employees. BMI was calculated by the Quetelet index as the ratio of the subject's body weight (in kg) to the square of the height (in meters). Periodontal status was recorded using the Community Periodontal Index (CPI). Binary multiple logistic regression analysis was done to assess the relation between BMI and periodontal status. The dependent variable for logistic regression analysis was categorized into control group (scores 0-2 of the CPI) and periodontitis group (scores 3 and 4 of the CPI). The overall prevalence of periodontal disease was 98.9%. Score 2 (bleeding and calculus) was the highest score prevailing among the subjects. They had an increased risk of periodontitis by 56% for each 1 kg/m(2) increase in BMI, which means that a higher BMI could be a potential risk factor for periodontitis among the adults aged 18 to 58 years. BMI evaluation could be used in the assessment of periodontal risk.

    Layout planning plays a key role in the inherent safety performance of process plants since this design feature controls the possibility of accidental chain-events and the magnitude of possible consequences. A lack of suitable methods to promote the effective implementation of inherent safety in layout design calls for the development of new techniques and methods. In the present paper, a safety assessment approach suitable for layout design in the critical early phase is proposed. The concept of inherent safety is implemented within this safety assessment; the approach is based on an integrated assessment of inherent safety guideword applicability within the constraints typically present in layout design. Application of these guidewords is evaluated along with unit hazards and control devices to quantitatively map the safety performance of different layout options. Moreover, the economic aspects related to safety and inherent safety are evaluated by the method. Specific sub-indices are developed within the integrated safety assessment system to analyze and quantify the hazard related to domino effects. The proposed approach is quick in application, auditable and shares a common framework applicable in other phases of the design lifecycle (e.g. process design). The present work is divided in two parts: Part 1 (current paper) presents the application of inherent safety guidelines in layout design and the index method for safety assessment; Part 2 (accompanying paper) describes the domino hazard sub-index and demonstrates the proposed approach with a case study, thus evidencing the introduction of inherent safety features in layout design.

    Manually indexed Internet health catalogs such as CliniWeb or CISMeF provide resources for retrieving high-quality health information. Users of these quality-controlled subject gateways are most often referred to them by general search engines such as Google, AltaVista, etc. This raises several questions, among which the following: what is the relative visibility of medical Internet catalogs through search engines? This study addresses this issue by measuring and comparing the visibility of six major, MeSH-indexed health catalogs through four different search engines (AltaVista, Google, Lycos, Northern Light) in two languages (English and French). Over half a million queries were sent to the search engines; for most of these search engines, according to our measures at the time the queries were sent, the most visible catalog for English MeSH terms was CliniWeb and the most visible one for French MeSH terms was CISMeF.

    The wildfire-water risk (WWR) has been defined as the potential for wildfires to adversely affect water resources that are important for downstream ecosystems and human water needs for adequate water quantity and quality, therefore compromising the security of their water supply. While tools and methods are numerous for watershed-scale risk analysis, the development of a toolbox for the large-scale evaluation of the wildfire risk to water security has only started recently. In order to provide managers and policy-makers with an adequate tool, we implemented a method for the spatial analysis of the global WWR based on the Driving forces-Pressures-States-Impacts-Responses (DPSIR) framework. This framework relies on the cause-and-effect relationships existing between the five categories of the DPSIR chain. As this approach heavily relies on data, we gathered an extensive set of spatial indicators relevant to fire-induced hydrological hazards and water consumption patterns by human and natural communities. When appropriate, we applied a hydrological routing function to our indicators in order to simulate downstream accumulation of potentially harmful material. Each indicator was then assigned a DPSIR category. We collapsed the information in each category using a principal component analysis in order to extract the most relevant pixel-based information provided by each spatial indicator. Finally, we compiled our five categories using an additive indexation process to produce a spatially-explicit index of the WWR. A thorough sensitivity analysis has been performed in order to understand the relationship between the final risk values and the spatial pattern of each category used during the indexation. For comparison purposes, we aggregated index scores by global hydrological regions, or hydrobelts, to get a sense of regional DPSIR specificities. This rather simple method does not necessitate the use of complex physical models and provides a scalable and efficient tool

    Background: Systematic reviews and meta-analysis have significant advantages over conventional reviews in that all available data should be presented. This study aimed to evaluate Iranian systematic reviews and meta-analysis abstracts indexed in WOS and Scopus during 2003-2012 based on PRISMA checklist. Methods: This is an analytical study. We evaluated 46 article abstracts indexed in WOS, 89 article abstracts indexed in Scopus and 158 article abstracts indexed in WOS and Scopus both (overlapped group). The quality of the abstracts was evaluated according to the PRISMA checklist for abstracts. Some indicators including distribution per year, total citation, average citations per year, average citations per documents and average citations per year in each article were determined through searching the WOS and Scopus Databases' analytical section. Then, the correlations between the abstract's PRISMA scores, average citations per year, and publication year were calculated. Results: The abstract's quality is not desirable as far as the PRISMA criteria are concerned. In other words, none of the articles' abstracts is in line with the PRISMA items. The average of scores of the current study was 5.9 while the maximum score was 12. The PRISMA criteria showed the highest compliance with "Objectives" (98.6%), the second highest with "Synthesis of result" (85%) and "Title" (80.2%) and the lowest compliance with "Registration" (2%). There was a positive correlation between the compliance of PRISMA score and the average citations per year while there was a negative correlation between PRISMA score and the publication year. Conclusion: It seems that the suggested criteria for reporting Iranian systematic reviews and meta-analysis are not considered adequately by the writers and even scientific journal editors.

  15. Nectarine Fruit Ripening and Quality Assessed Using the Index of Absorbance Difference (IAD)

    OpenAIRE

    Bonora, E.; D. Stefanelli; Costa, G

    2013-01-01

    Consistency of fruit quality is extremely important in horticulture. Fruit growth and quality in nectarine are affected by fruit position in the canopy, related to the tree shape. The “open shaped” training systems, such as Tatura Trellis, improve fruit growth and quality. The Index of Absorbance Difference (IAD) is a new marker that characterizes climacteric fruit during ripening.

    The aim of this study is to review the features, benefits and limitations of the new scientific evaluation products derived from Google Scholar, such as Google Scholar Metrics and Google Scholar Citations, as well as the h-index, which is the standard bibliometric indicator adopted by these services. The study also outlines the potential of this new database as a source for studies in Biomedicine, and compares the h-index obtained by the most relevant journals and researchers in the field of intensive care medicine, based on data extracted from the Web of Science, Scopus and Google Scholar. Results show that although the average h-index values in Google Scholar are almost 30% higher than those obtained in Web of Science, and about 15% higher than those collected by Scopus, there are no substantial changes in the rankings generated from one data source or the other. Despite some technical problems, it is concluded that Google Scholar is a valid tool for researchers in Health Sciences, both for purposes of information retrieval and for the computation of bibliometric indicators.

    To assess the DMFT index of children with Special Health Care Needs (SHCN) in Navi Mumbai. To correlate the DMFT index with Streptococcus mutans count in the supragingival bacterial biofilm and with plaque pH. Dental examination of 158 patients aged 5-18 years was conducted to determine the DMFT/dmft index. Supragingival plaque samples were collected from the buccal surfaces of all teeth. The samples were inoculated in mitis salivarius bacitracin agar medium and incubated at 37°C for 48 h. Supragingival plaque was collected from interproximal sites of the molar area (preferably mandibular) for conducting plaque pH test. Chi-square test and Pearson's correlation were used to find the significance of the study parameters on categorical scale between the two groups. The mean DMFT recorded was 4.90 ± 4.63 and the mean dmft recorded was 1.77 ± 3.14. Mean number of S. mutans colony-forming units found was 2.961 × 10(4). Mean plaque pH recorded was 6.2. No statistically significant correlation was found between the DMFT index with the number of S. mutans and plaque pH.

    Obliterative arteriopathy of the lower limbs is a severe disease. History taking often underestimates prevalence. In studies using the Rose questionnaire and examining the prevalence of symptomatic arteriopathy defined by the presence of intermittent claudication, prevalence has been rather constant, around 2% in the general population in industrialized countries. A more clinical approach searching for physical anomalies (absence of distal pulse) generally gives higher rates. The most recent data led us to conduct a study focusing on screening for arterial disease using the systolic index (the systolic index is the ratio between the ankle and humeral systolic pressure). A systolic index below 0.90 would be a sign of defective perfusion, increasing in severity with poorly compensated arterial lesions. A survey was performed in a random sample of 150 practitioners using an allocation procedure to the nearest colleague in case of refusal. A data sheet containing demographic data and the main risk factors was established for each consulting patient aged from 40 to 80 years. The systolic index was measured in each patient with at least one vascular risk or who consulted for pain in the lower limbs. A simple sequential non-randomized patient recruitment scheme was used. The survey population included nearly 9,000 patients (8,987), 46% men and 54% women, mean age 64 years (table I). Patient risk factors including smoking, diabetes, hypertension, and physical exercise were adjusted for sex and age (table II-VI, IX). The systolic index was recorded in 41% of the population who had a vascular risk factor. Among these patients, nearly one-fourth had a systolic index under 0.90, giving a prevalence in the sample population of 11% (table VII). This rate was also assessed by age and sex (table VIII). Logistic regression evidenced a prognostic value (fig. 1) for smoking, hypertension and sedentary activity, and to a lesser extent, for age and sex. There was a significant

    Full Text Available In the present work, the assessment of drinking water quality was carried out through a monitoring of heavy metals in the treated and consumed waters in the city of Nouakchott (Mauritania. Monthly sampling was conducted for a period of 24 months between January 2012 and December 2013. Nine parameters were evaluated: pH, T (°C, Turbidity (NTU, Al, Fe, Cu, Mn, Al2(SO43 and CaO. Indexing approaches have been applied by calculating the Heavy Metal Pollution Index (HPI and Metal Index (MI for the assessment of influence of heavy metals on the overall quality of water. The obtained results for heavy metals are in good agreement with World Health Organization (WHO standards. Though the aluminum concentration remains in the limits set by WHO, yet it shows a major contribution in the indices. This has been verified by the statistical analysis which demonstrates fair correlations between aluminum, HPI (r = 0.9 and MI (r = 0.77. Aluminum showed the important influence of seasonal change in the year as well as the doses of reagents injected during the treatment process on the concentration of aluminum is detailed.

    Full Text Available Forest management intensity often affects biodiversity, ecosystem processes and ecosystem services. To assess the influence of past management intensity on current ecosystem properties, management intensity must be quantified in a meaningful and reproducible approach. Here we developed the simple yet effective Forest Management Intensity index (ForMI, which is based only on inventory data of the living stand, stumps and dead wood. The ForMI is the sum of three components taking into account: 1. the proportion of harvested tree volume (Iharv, 2. the proportion of tree species that are not part of the natural forest community (Inonat and 3. the proportion of dead wood showing signs of saw cuts (Idwcut. Each component ranges between 0 (no sign of management and 1 (intensive management. Our analysis suggests that the ForMI can be used to assess management intensity in Central European forests for the last 30 to 40 years, depending on decay rates of stumps and dead wood. Our approach was tested using data of 148 forest plots of 1 ha in size in Germany. We found a significant distinction between plots that were previously described as managed and unmanaged as well as between plots comprising trees species of the natural forest community and those with additional, introduced coniferous tree species. We conclude that the index is applicable to a wide range of forest management types, but should not be misinterpreted as an index for old-growth structure.

  1. Use of Clearance Indexes to Assess Waste Disposal Issues for the HYLIFE-II Inertial Fusion Energy Power Plant Design

    2002-01-17

    Traditionally, waste management studies for fusion energy have used the Waste Disposal Rating (WDR) to evaluate if radioactive material from irradiated structures could qualify for shallow land burial. However, given the space limitations and the negative public perception of large volumes of waste, there is a growing international motivation to develop a fusion waste management system that maximizes the amount of material that can be cleared or recycled. In this work, we present an updated assessment of the waste management options for the HYLIFE-II inertial fusion energy (IFE) power plant, using the concept of Clearance Index (CI) for radioactive waste disposal. With that purpose, we have performed a detailed neutronics analysis of the HYLIFE-II design, using the TART and ACAB computer codes for neutron transport and activation, respectively. Whereas the traditional version of ACAB only provided the user with the WDR as an index for waste considerations, here we have modified the code to calculate Clearance Indexes using the current International Atomic Energy Agency (IAEA) clearance limits for radiological waste disposal. The results from the analysis are used to perform an assessment of the waste management options for the HYLIFE-II IFE design.

    Full Text Available Abstract Background Research has shown that fecal biomarkers are useful to assess the activity of inflammatory bowel disease (IBD. The aim of the study is: to evaluate the efficacy of the fecal lactoferrin and calprotectin as indicators of inflammatory activity. Findings A total of 78 patients presenting inflammatory bowel disease were evaluated. Blood tests, the Crohn's Disease Activity Index (CDAI, Mayo Disease Activity Index (MDAI, and Crohn's Disease Endoscopic Index of Severity (CDEIS were used for the clinical and endoscopic evaluation. Two tests were performed on the fecal samples, to check the levels of calprotectin and lactoferrin. The performance of these fecal markers for detection of inflammation with reference to endoscopic and histological inflammatory activity was assessed and calculated sensitivity, specificity, accuracy. A total of 52 patient's samples whose histological evaluations showed inflammation, 49 were lactoferrin-positive, and 40 were calprotectin-positive (p = 0.000. Lactoferrin and calprotectin findings correlated with C-reactive protein in both the CD and UC groups (p = 0.006; p = 0.000, with CDAI values (p = 0.043; 0.010, CDEIS values in DC cases (p = 0,000; 0.000, and with MDAI values in UC cases (p = 0.000. Conclusion Fecal lactoferrin and calprotectin are highly sensitive and specific markers for detecting intestinal inflammation. Levels of fecal calprotectin have a proportional correlation to the degree of inflammation of the intestinal mucosa.

    Full Text Available Several complications during childhood is associated with nutritional status of infants at birth. Therefore, nutritional status of newborns must be evaluated properly after birth. Assessment of the nutritional status of neonates based on anthropometric and physical indices is simple and inexpensive without the need for advanced medical equipment. However, no previous studies have focused on the assessment methods of the nutritional status of infants via anthropometric and physical indices. This study aimed to review some of the key methods used to determine the nutritional status of neonates using anthropometric and physical indices. To date, most studies have focused on the diagnosis of fetal malnutrition (FM and growth monitoring. In order to diagnose FM, researchers have used growth charts and Ponderal index (PI based on anthropometric indices, as well as Clinical Assessment of Nutritional (CAN Score based on physical features. Moreover, in order to assess the growth status of infants, growth charts were used. According to the findings of this study, standard intrauterine growth curves and the PI are common measurement tools in the diagnosis of FM. Furthermore, CAN score is widely used in the evaluation of the nutritional status of neonates. Given the differences in the physical features of term and preterm infants, this index should be adjusted for preterm neonates. Longitudinal growth charts are one of the most prominent methods used for monitoring of the growth patterns of infants.

    Readmission after pancreatectomy is common, but few data compare patterns of readmission to index and nonindex hospitals. To evaluate the rate of readmission to index and nonindex institutions following pancreatectomy at a tertiary high-volume institution and to identify patient-level factors predictive of those readmissions. Retrospective analysis of a prospectively collected institutional database linked to statewide data of patients who underwent pancreatectomy at a tertiary care referral center between January 1, 2005, and December 2, 2010. Pancreatectomy. The primary outcome was unplanned 30-day readmission to index or nonindex hospitals. Risk factors and reasons for readmission were measured and compared by site using univariable and multivariable analyses. Among all 623 patients who underwent pancreatectomy during the study period, 134 (21.5%) were readmitted to our institution (105 [78.4%]) or to an outside institution (29 [21.6%]). Fifty-six patients (41.8%) were readmitted because of a gastrointestinal or nutritional problem related to surgery and 42 patients (31.3%) because of a postoperative infection. On multivariable analysis, factors independently associated with readmission included age 65 years or older (odds ratio [OR], 1.80; 95% CI, 1.19-2.71), preexisting liver disease (OR, 2.28; 95% CI, 1.23-4.24), distal pancreatectomy (OR, 1.77; 95% CI, 1.11-2.84), and postoperative drain placement (OR, 2.81; 95% CI, 1.00-7.14). In total, 21.5% of patients required early readmission after pancreatectomy. Even in the setting of a tertiary care referral center, 21.6% of these readmissions were to nonindex institutions. Specific patient-level factors were associated with an increased risk of readmission.

    The analysis of literature data was carried out and performed research justifying the epidemic value of detection in water P. aeruginosa in drinking and domestic water use. The were revealed features of the vital activity of P aeruginosa in water bodies as opposed to conventional microbiological indicators. It was shown that the coliform group indices can not guarantee the epidemic safety of drinking water use in relation to P aeruginosa. The data obtained justify the need for the introduction of P aeruginosa as an additional index in monitoring the water quality of centralized and decentralized water supply.

    In Entre Ríos (Argentina), rice cultivation is carried out mainly in Vertisols. Several factors, such as the use of sodium bicarbonate waters for irrigation, the excessive tillage required, and the lack of proper planning for land use, mainly regarding the crop sequence, cause serious impacts on the soil and have an effect on sustainable agriculture. Thus, the development of methodologies to detect these impacts has become a priority. The aim of this study was to standardize soil quality indicators (SQI) and integrate them into an index to evaluate the impacts of the rice production system on soil, at the farm scale. The study was conducted in farms of the traditional rice cultivation area of Entre Ríos province, Argentina. We evaluated a minimum data set consisting of six indicators: structural stability and percolation, total organic matter content (TOM), exchangeable sodium content (ESC), electrical conductivity of saturation extract (ECe) and reaction of the soil (pH). From a database from 75 production lots, we determined the reference values, i.e. limits to ensure the maintenance of long-term productivity and the allowable thresholds for each indicator. The indicators were standardized and integrated into a soil quality index. Five ranges of soil quality were established: very low, low, moderate, high and very high, depending on the values assigned to each SQI. This index allowed differentiating the impact of different crop sequences and showed that the increased participation of rice crop in the rotation resulted in a deterioration of the soil structure due to the decrease in the TOM and to the cumulative increase in ESC caused by the sodium bicarbonate water used for irrigation. Soil management strategies should aim to increase TOM values and to reduce the input of sodium to the exchange complex. A rotation with 50% to 60% of pasture and 40 to 50% of agriculture with a participation of rice lower than 20 to 25% would allow the sustainability of the

    Rivers are one of the main water resources for agricultural, drinking, environmental and industrial use. Water quality indices can and have been used to identify threats to water quality along a stream and contribute to better water resources management. There are many water quality indices for the assessment and use of surface water for drinking purposes. However, there is no well-established index for the assessment and direct use of river water for irrigation purposes. The aim of this study was to adopt the framework of the National Sanitation Foundation Water Quality Index (NSFWQI) and, with adjustments, apply it in a way which will conform to irrigation water quality requirements. To accomplish this, the NSFWQI parameters for drinking water use were amended to include water quality parameters suitable for irrigation. For each selected parameter, an individual weighting chart was generated according to the FAO 29 guideline. The NSFWQI formula was then used to calculate a final index value, and for each parameter an acceptable range in this value was determined. The new index was then applied to the Ghezel Ozan River in Iran as a case study. A forty five year record of water quality data (1966 to 2010) was collected from four hydrometery stations along the river. Water quality parameters including Na + , Cl - , pH, HCO - 3, EC, SAR and TDS were employed for water quality analysis using the adjusted NSFWQI formula. The results of this case study showed variation in water quality from the upstream to downstream ends of the river. Consistent monitoring of the river water quality and the establishment of a long term management plan were recommended for the protection of this valuable water resource.

    Full Text Available The present study on body mass index and health related physical fitness of school children was undertaken with the view of portraying the health related fitness profile of school children in Kannur district of Kerala. Data on body mass index and health related fitness according to ICHPER.SD Asia Youth Health Related Fitness test was collected from 1000 school children from different schools of Kannur district, Kerala. The study had sub samples of 250 boys and 250 girls from schools belonging to urban areas; and 250 boys and 250 girls belonging to rural areas. The data on BMI and health related fitness variables of the study were comparable to the data of Indian counterparts shown in previous studies. The analysis of data revealed that girls had significantly greater BMI as compared to boys. However, boys scored significantly better than girls on one milerun, sit ups and modified pull ups. Girls were significantly better than boys in case of flexibility performance in the sit and reach test. In case of sum of skinfolds, girls had significantly greater skinfold measurements as compared to boys. Rural sample of school children scored significantly better than urban school children inmodified pull ups. In case of sum of skinfolds, urban school children had greater skinfold measurements as compared to their rural counterparts. The study warrants the need for further investigations covering a wider segment of population and taking other vital parameters such as nutritional status, physical activity patterns, andsocio-economic conditions so as to obtain meaningful relationships.

    There are several methodology based on voice analysis to evaluate nasal airway. Here we introduce a new quantitative index based on voice spectrum analysis to evaluate nasal obstruction. Ten subjects of nasal blockage were instructed to produced the sustained consonant-vowel syllable /m partial partial differential/ at comfortable levels of speech for at least 5 seconds. After nasal decongestant treatment, the second voice sample was collected. Sound spectrum was obtained by the algorithm of fast Fourier transform and the fundamental frequency (F0) was calculated by the method of autocorrelation. Voice low tone to high tone ratio (VLHR) was defined as the division of low frequency power (LFP) into high frequency power (HFP) of the sound power spectrum and was finally expressed in decibels. The cut-off frequency was the product of F0 and square root of (4 x 5). The VLHR after nasal decongestant treatment increased significantly as compared with that before treatment (P voice during treatment for nasal obstruction. The index is quantitative, non-invasive, and potentially useful for basic researches and clinical applications.

    The optimal concentration Copt of a pollutant in the environment can be determined as an equilibrium point in the trade off between (i) environmental cost, due to impact on man/ecosystem/economy, and (ii) economic cost for environmental protection, as it can be expressed by Pigouvian tax. These two conflict variables are internalized within the same techno-economic objective function of total cost, which is minimized. In this work, the first conflict variable is represented by a Willingness To Pay (WTP) index. A methodology is developed for the estimation of this index by using fuzzy sets to count for uncertainty. Implementation of this methodology is presented, concerning odor pollution of air round an olive pomace oil mill. The ASTM E544-99 (2004) 'Standard Practice for Referencing Suprathreshold Odor Intensity' has been modified to serve as a basis for testing, while a network of the quality standards, required for the realization/application of this 'Practice', is also presented. Last, sensitivity analysis of Copt as regards the impact of (i) the increase of environmental information/sensitization and (ii) the decrease of interest rate reveals a shifting of Copt to lower and higher values, respectively; certain positive and negative implications (i.e., shifting of Copt to lower and higher values, respectively) caused by socio-economic parameters are also discussed.

    Atrial Fibrillation (AF), a chaotic rhythm classically considered with random electrical activity, is now demonstrated to show a certain degree of organization and synchronization. Rather than those traditional indices which always focus on the pairwise properties of adjacent signals, a new synchronization index-S estimator-is introduced in this paper to quantify the synchronization level for all the signals in a selected area. By evaluating a complement of the entropy of the normalized eigenvalues of the corresponding correlation matrix, S estimator is designed to be proportional to the amount of synchronization. 400 episodes of 64-channel epicardial signals acquired from four living mongrels were studied under normal sinus rhythm (SN) and AF. The results showed that there were significant decreases of S estimator for both anterior left atrium and anterior right atrium with the rhythm changing from SN to AF. After dividing the research area into eight subparts, S estimator is also capable to demonstrate the different synchronization level for each subpart and revealed the electrophysiology individual difference among four experimental subjects. In conclusion, S estimator succeeds in estimating the synchronization degree for multi-channel signals in a selected area, with no limits to the number of the signals to be analyzed. It can help us to distinguish the region with a high synchronization level during AF, which would be helpful to the clinical AF treatment and enhance our understanding of underlying mechanisms of AF.

    Full Text Available Surface sediments (0-5 cm from 21 stations throughout Klang River were sampled for metal concentration as well sediment's pH, total organic carbon (TOC and particles sizes to obtain an overall classification of metal contaminations in the area. The concentration of metals (µg∕g, Fe%, dw were as follows: 0.57- 2.19 Cd; 31.89-272.33 Zn; 5.96-24.47 Ni; 10.57- 52.87 Cu; 24.23-64.11 Pb and 1.56-3.03 Fe. The degree of sediment contaminations were computed using an enrichment factor (EF and geoaccumulation index (Igeo. The results suggested that enrichment factor and geoaccumulation values of Cd were greatest among the studied metals. Pearson's correlation indicated that effectiveness of TOC in controlling the distribution and enrichment of metals was a more important factor than that of the grain size (< 63µm. The study revealed that on the basis of computed indexes, Klang River is classified as moderately polluted river.

    2013-09-01

    A new estuarine trophic state index - Keratella-index (KIN), based on the relative abundance of two common rotifer species, Keratella cochlearis and Keratella tecta, was developed and tested for the Neva Estuary (Gulf of Finland, Baltic Sea). The morphological trait variation of these plankton species and their responses to different trophic conditions were investigated at three nearshore stations. The morphological data confirm that K. cochlearis and K. tecta are likely to be two distinct species (not two morphs) at our study site. The mean lorica length of K. cochlearis and K. tecta differ significantly and there were no K. cochlearis individuals with extremely short spines (rotifers K. cochlearis and K. tecta, the increase of which indicates and increase in estuarine trophic state. The success of unspined K. tecta compared to spined K. cochlearis may be explained by the "rare-enemy effect". There was a significant correlation (R2 = 0.76; p < 0.001; R2 = 0.68; p < 0.01) between KIN and the common trophic state indices (TSI and QB/T, respectively). The KIN values indicated meso-eutrophic to strongly eutrophic conditions at different nearshore sampling sites and hence indicated that the Neva Estuary is eutrophic.

    To determine the periodontal status and treatment needs among dental fluorosis subjects residing in Ennore, Chennai, using Community Periodontal Index of Treatment Needs (CPITN). All the subjects with dental fluorosis above 15 years of age, permanent residents of Ennore, were included in the study. Subjects with known systemic diseases and subjects with other intrinsic dental stains were excluded from the study. Periodontal status was estimated using CPITN and Dental fluorosis was recorded using Dean's Dental Fluorosis Index. The total number of study subjects was 1075, of which 489 were males and 586 were females. Males were predominantly affected with periodontal disease than females. This was found to be statistically significant (P=0.000). The association between Degree of Fluorosis and Periodontal Status is statistically significant (P=0.000). There was statistically significant difference in mean number of sextants between the degree of fluorosis in each of the periodontal status (P=0.000). The finding that the lower prevalence of shallow pockets in the study area, where the fluoride level in the drinking water ranges from 1.83 to 2.01 ppm, indicates that the use of fluoride in water is beneficial to the periodontal tissues.

    Eco-design is an advanced design approach which plays an important part in the national innovation project and serves as a key point for the successful transformation of the supply structure. However, the practical implementation of the pro-environmental designs and technologies always faces a dilemma situation, where some processes can effectively control their emissions to protect the environment at relatively high costs, while others pursue the individual interest in making profit by ignoring the possible adverse environmental impacts. Thus, the assessment on the eco-design process must be carried out based on the comprehensive consideration of the economic and environmental aspects. Presently, the assessment systems in China are unable to fully reflect the new environmental technologies regarding their innovative features or performance. Most of the assessment systems adopt scoring method based on the judgments of the experts, which are easy to use but somewhat subjective. The assessment method presented in this paper includes the environmental impact (EI) assessment based on LCA principal and willingness-to-pay theory, and economic profit (EP) assessment mainly based on market price. The results from the assessment are in the form of EI/EP, which evaluate the targeted process from a combined perspective of environmental and economic performance. A case study was carried out upon the utilization process of coal fly ash, which indicates the proposed method can compare different technical processes in an effective and objective manner, and provide explicit and insightful suggestions for decision making.

  17. Development of a water state index to assess the severity of impacts on and changes in natural water resources.

    2008-01-01

    Lifecycle assessment (LCA) is a standardised methodology that is used to assess the impact of techno-economic systems on the natural environment. By compiling an inventory of energy and material inputs and environmental releases or outputs of a system, and evaluating the potential environmental impacts associated with the inventory, one can make an informed decision regarding the sustainability of a techno-economic system in question. However, the current lifecycle impact assessment (LCIA) methodologies that form part of LCA studies do not effectively consider the impacts of techno-economic systems on ground and surface water resources in South Africa (and elsewhere). It is proposed that a microbiology based index method, similar to methods proposed for terrestrial resources, can establish the states of water resources for six classes of current economic exploitation: protected, moderate use, degraded, cultivated, plantation, and urban. It is further suggested that changes in these classes (and states) can be used meaningfully in LCIA methodologies to quantify the extent to which techno-economic interventions may alter natural water resources. Research is recommended to further improve the accuracy and reliability of the water state index. IWA Publishing 2008.

    Introduction. Outcome evaluation is an important aspect of the treatment of patients with degenerative lumbar disease. We evaluated the usefulness of the Core Outcome Measures Index (COMI) in assessing people affected by degenerative lumbar disease in daily clinical practice. Methods. We evaluated 221 patients who had completed preoperatively and 2 years after surgery VAS pain, Short Form-36 (SF-36), Oswestry Disability Index (ODI) and COMI. We calculated the change of scores and its sensitivity to change. The internal consistency of the COMI items and the correlation between the COMI scores and the scores of the other measurements were assessed. Results. Statistically significant differences were observed between the mean scores of the preoperative and 2 years questionnaires for nearly all measurements. COMI showed a good internal consistency, except for the preoperative pain subscale. The sensitivity to change was high for the total COMI and its pain and well-being subscales and moderate for the rest. The COMI demonstrated strong correlation with the other measurements. Conclusions. The COMI is a useful tool for assessing the patient-based outcome in the studied population. Given its simplicity, good correlation with the SF-36 and ODI and its good sensitivity to change, it could replace more cumbersome instruments in daily clinical practice.

    Understanding acetabular pathomorphology is necessary to correctly treat patients with hip complaints. Existing radiographic parameters classify acetabular coverage as deficient, normal, or excessive but fail to quantify contributions of anterior and posterior wall coverage. A simple, reproducible, and valid measurement of anterior and posterior wall coverage in patients with hip pain would be a clinically useful tool. We (1) introduce the anterior wall index (AWI) and posterior wall index (PWI), (2) report the intra- and interobserver reliability of these measurements, and (3) validate these measurements against an established computer model. We retrospectively reviewed 87 hips (63 patients) with symptomatic hip disease. A validated computer model was used to determine total anterior and posterior acetabular coverage (TAC and TPC) on an AP pelvis radiograph. Two independent observers measured the AWI and PWI on each film, and the intraclass correlation coefficient (ICC) was calculated. Pearson correlation was used to determine the strength of linear dependence between our measurements and the computer model. Intra- and interobserver ICCs were 0.94 and 0.99 for the AWI and 0.81 and 0.97 for the PWI. For validation against the computer model, Pearson r values were 0.837 (AWI versus TAC) and 0.895 (PWI versus TPC). Mean AWI and PWI were 0.28 and 0.81 for dysplastic hips, 0.41 and 0.91 for normal hips, 0.61 and 1.15 for hips with a deep acetabulum. Our data suggest these measures will be helpful in evaluating anterior and posterior coverage before and after surgery but need to be evaluated in asymptomatic individuals without hip abnormalities to establish normal ranges.

    Augmentation index (AIx) is widely used as a measure of wave reflection. We compared the relationship between AIx and age, height and sex with 'gold standard' measures of wave reflection derived from measurements of pressure and flow to establish how well AIx measures wave reflection. Measurements of carotid pressure and flow velocity were made in the carotid artery of 65 healthy normotensive individuals (age 21-78 yr; 43 male) and pulse wave analysis, wave intensity analysis and wave separation was performed; waveforms were classified into type A, B or C. AIx, the time of the first shoulder (T(s)), wave reflection index (WRI) and the ratio of backward to forward pressure (P(b)/P(f)) were calculated. AIx did not correlate with log WRI or P(b)/P(f). When AIx was restricted to positive values AIx and log WRI were positively correlated (r = 0.33; p = 0.04). In contrast log WRI and P(b)/P(f) were closely correlated (r = 0.66; pwave identified by wave intensity analysis. Wave intensity analysis showed that the morphology of type C waveforms (negative AIx) was principally due to a forward travelling (re-reflected) decompression wave in mid-systole. AIx correlated positively with age, inversely with height and was higher in women. In contrast log WRI and P(b)/P(f) showed negative associations with age, were unrelated to height and did not differ significantly by gender. AIx has serious limitations as a measure of wave reflection. Negative AIx values derived from Type C waves should not be used as estimates of wave reflection magnitude.

    Objective The aim of this study was to explore whether the Variable Lifting Index (VLI) can be corrected for cumulative mass and thus test its efficacy in predicting the risk of low-back pain (LBP). Background A validation study of the VLI method was published in this journal reporting promising results. Although several studies highlighted a positive correlation between cumulative load and LBP, cumulative mass has never been considered in any of the studies investigating the relationship between manual material handling and LBP. Method Both VLI and cumulative mass were calculated for 2,374 exposed subjects using a systematic approach. Due to high variability of cumulative mass values, a stratification within VLI categories was employed. Dummy variables (1-4) were assigned to each class and used as a multiplier factor for the VLI, resulting in a new index (VLI_CMM). Data on LBP were collected by occupational physicians at the study sites. Logistic regression was used to estimate the risk of acute LBP within levels of risk exposure when compared with a control group formed by 1,028 unexposed subjects. Results Data showed greatly variable values of cumulative mass across all VLI classes. The potential effect of cumulative mass on damage emerged as not significant ( p value = .6526). Conclusion When comparing VLI_CMM with raw VLI, the former failed to prove itself as a better predictor of LBP risk. Application To recognize cumulative mass as a modifier, especially for lumbar degenerative spine diseases, authors of future studies should investigate potential association between the VLI and other damage variables.

    The fact that the considered indexes were not able to find significant differences in the beta band might indicate that phase-coupling changes induced by the drug are weak or too subtle to be detected, given that all measures are corrected by a baseline recording. This might discourage their use in psychopharmacological studies when assessing low doses, mild effects, or when working with a reduced number of participants. However, correlations with plasma concentrations remained high, indicating that PLI, WPLI and IC should not be totally discarded as means of evaluating pharmacological effects on the brain via EEG recordings.

    Leaf carotenoids content (LCar) is an important indicator of plant physiological status. Accurate estimation of LCar provides valuable insight into early detection of stress in vegetation. With spectroscopy techniques, a semi-empirical approach based on spectral indices was extensively used for carotenoids content estimation. However, established spectral indices for carotenoids that generally rely on limited measured data, might lack predictive accuracy for carotenoids estimation in various species and at different growth stages. In this study, we propose a new carotenoid index (CARI) for LCar assessment based on a large synthetic dataset simulated from the leaf radiative transfer model PROSPECT-5, and evaluate its capability with both simulated data from PROSPECT-5 and 4SAIL and extensive experimental datasets: the ANGERS dataset and experimental data acquired in field experiments in China in 2004. Results show that CARI was the index most linearly correlated with carotenoids content at the leaf level using a synthetic dataset (R2 = 0.943, RMSE = 1.196 μg/cm2), compared with published spectral indices. Cross-validation results with CARI using ANGERS data achieved quite an accurate estimation (R2 = 0.545, RMSE = 3.413 μg/cm2), though the RBRI performed as the best index (R2 = 0.727, RMSE = 2.640 μg/cm2). CARI also showed good accuracy (R2 = 0.639, RMSE = 1.520 μg/cm2) for LCar assessment with leaf level field survey data, though PRI performed better (R2 = 0.710, RMSE = 1.369 μg/cm2). Whereas RBRI, PRI and other assessed spectral indices showed a good performance for a given dataset, overall their estimation accuracy was not consistent across all datasets used in this study. Conversely CARI was more robust showing good results in all datasets. Further assessment of LCar with simulated and measured canopy reflectance data indicated that CARI might not be very sensitive to LCar changes at low leaf area index (LAI) value, and in these conditions soil moisture

    Full Text Available Proponents of the efficient market hypothesis believe that active portfolio management is largely wasted effort and unlikely to justify the expenses incurred. Therefore, they advocate a passive investment strategy that makes no attempt to outsmart the market. One common strategy for passive management is indexing where a fund is designed to replicate the performance of a broad-based index of stocks and bonds. Traditionally, indexing was used by institutional investors, but today, the use of index funds proliferated among individual investors. Over the years, both international and domestic index funds have disproportionately outperformed the market more than the actively managed funds have.

  9. How Universal Is the Relationship between Remotely Sensed Vegetation Indices and Crop Leaf Area Index? A Global Assessment

    Full Text Available Leaf Area Index (LAI is a key variable that bridges remote sensing observations to the quantification of agroecosystem processes. In this study, we assessed the universality of the relationships between crop LAI and remotely sensed Vegetation Indices (VIs. We first compiled a global dataset of 1459 in situ quality-controlled crop LAI measurements and collected Landsat satellite images to derive five different VIs including Simple Ratio (SR, Normalized Difference Vegetation Index (NDVI, two versions of the Enhanced Vegetation Index (EVI and EVI2, and Green Chlorophyll Index (CIGreen. Based on this dataset, we developed global LAI-VI relationships for each crop type and VI using symbolic regression and Theil-Sen (TS robust estimator. Results suggest that the global LAI-VI relationships are statistically significant, crop-specific, and mostly non-linear. These relationships explain more than half of the total variance in ground LAI observations (R2 > 0.5, and provide LAI estimates with RMSE below 1.2 m2/m2. Among the five VIs, EVI/EVI2 are the most effective, and the crop-specific LAI-EVI and LAI-EVI2 relationships constructed by TS, are robust when tested by three independent validation datasets of varied spatial scales. While the heterogeneity of agricultural landscapes leads to a diverse set of local LAI-VI relationships, the relationships provided here represent global universality on an average basis, allowing the generation of large-scale spatial-explicit LAI maps. This study contributes to the operationalization of large-area crop modeling and, by extension, has relevance to both fundamental and applied agroecosystem research.

  10. Using the H-index to assess disease priorities for salmon aquaculture.

    Atlantic salmon's (Salmo salar) annual aquaculture production exceeds 2M tonnes globally, and for the UK forms the largest single food export. However, aquaculture production is negatively affected by a range of different diseases and parasites. Effort to control pathogens should be focused on those which are most "important" to aquaculture. It is difficult to specify what makes a pathogen important; this is particularly true in the aquatic sector where data capture systems are less developed than for human or terrestrial animal diseases. Mortality levels might be one indicator, but these can cause a range of different problems such as persistent endemic losses, occasional large epidemics or control/treatment costs. Economic and multi-criteria decision methods can incorporate this range of impacts, however these have not been consistently applied to aquaculture and the quantity and quality of data required is large, so their potential for comparing aquatic pathogens is currently limited. A method that has been developed and applied to both human and terrestrial animal diseases is the analysis of published scientific literature using the H-index method. We applied this method to salmon pathogens using Web of Science searches for 23 pathogens. The top 3 H-indices were obtained for: sea lice, furunculosis, and infectious salmon anaemia; post 2000, Amoebic Gill Disease (AGD) replaced furunculosis. The number of publications per year describing bacterial disease declined significantly, while those for viruses and sea lice increased significantly. This reflects effective bacterial control by vaccination, while problems related to viruses and sea lice have increased. H-indices by country reflected different national concerns (e.g. AGD ranked top for Australia). Averaged national H-indices for salmon diseases tend to increase with log of salmon production; countries with H-Indices significantly below the trend line have suffered particularly large disease losses. The H-index

    Full Text Available INTRODUCTION: The present study aims to prospectively compare the sexual function in males before and after vasectomy surgery using the international index of erectile function (IIEF. MATERIALS AND METHODS: From October to December 2002, sixty-four patients who were candidates for male sterilization in the vasectomy program of the Urology Section at the General Hospital of the University of São Paulo were included. The same investigator applied the IIEF before and 90 days after the surgery. The mean scores obtained on pre and postoperative visits for all domains of sexual function were analyzed and compared with the Wilcoxon test. RESULTS: The mean patient age was 35 years (range from 25 to 48 years and the mean number of children per man was 3. The total mean score of the IIEF was 64.06 before surgery and 65.64 after the procedure, with this difference considered statistically significant (p < 0.001. Sixty-seven per cent of the patients improved their scores, versus 17% and 16% who showed worsening or no change at all in IIEF scores following surgery, respectively. Of the 5 sexual function domains, desire and sexual satisfaction presented statistically significant improvement. CONCLUSION: This study showed that vasectomy caused a positive impact on sexual function, especially on desire and sexual satisfaction, in the majority of men undergoing surgery. There was no case of surgery-related erectile dysfunction.

    Recent studies have identified various bacterial groups that are altered in dogs with chronic inflammatory enteropathies (CE) compared to healthy dogs. The study aim was to use quantitative PCR (qPCR) assays to confirm these findings in a larger number of dogs, and to build a mathematical algorithm to report these microbiota changes as a dysbiosis index (DI). Fecal DNA from 95 healthy dogs and 106 dogs with histologically confirmed CE was analyzed. Samples were grouped into a training set and a validation set. Various mathematical models and combination of qPCR assays were evaluated to find a model with highest discriminatory power. The final qPCR panel consisted of eight bacterial groups: total bacteria, Faecalibacterium, Turicibacter, Escherichia coli, Streptococcus, Blautia, Fusobacterium and Clostridium hiranonis. The qPCR-based DI was built based on the nearest centroid classifier, and reports the degree of dysbiosis in a single numerical value that measures the closeness in the l2 - norm of the test sample to the mean prototype of each class. A negative DI indicates normobiosis, whereas a positive DI indicates dysbiosis. For a threshold of 0, the DI based on the combined dataset achieved 74% sensitivity and 95% specificity to separate healthy and CE dogs. © FEMS 2017. All rights reserved.

    Residency programs are increasingly being asked to defend their quality, and that of the residents they produce. Yet "residency quality" is a construct that has not been well defined, with no accepted standards other than meeting accreditation standards. In 2009, the Association of Family Medicine Residency Directors developed a strategic plan that included the goal of raising the quality of family medicine training. We describe the development of this quality improvement tool, which we called the residency performance index (RPI), and its first year of use by family medicine residency programs. We describe the use of the tool as a "dashboard" to facilitate program self-improvement. Using program metrics specific to family medicine training, and benchmark criteria for these metrics, the RPI was launched in 2012 to help programs identify strengths and areas for improvement in their educational activities and resident clinical experiences that could be tracked and reviewed as part of the annual program evaluation. Approximately 100 program directors began using the tool and 70 finished the process, and were provided aggregate data. Initial review of this experience revealed difficulties with collecting data, and lack of information on graduates' scope of practice. It also showed the potential usefulness of the tool as a program improvement mechanism. The RPI is a new quality improvement tool for family medicine residency programs. Although some initial challenges need to be addressed, it has the promise to aid family medicine residency in its internal improvement efforts.

    The aim of the present study is to determine the frequency of enthesopathy in fibromyalgia (FM) by using a newly developed ultrasonography (US) method, the Madrid Sonography Enthesitis Index (MASEI). This study was conducted on 38 consecutive patients with FM and 48 healthy sex- and age-matched controls. Six entheseal sites (olecranon tuberosity, superior and inferior poles of patella, tibial tuberosity, superior and inferior poles of calcaneus) on both lower limbs were evaluated. All US findings were identified according to MASEI. Scores of patients and controls were compared by Student's t-test and Mann-Whitney U-test. Validity was analysed by receiver operating characteristic curve. Values of P FM patients and 3.7 ± 3.22 among healthy controls (P 3.5 in the FM group as the best cut-off point to differentiate between cases and controls. No statistically significant correlation was found between the MASEI score and the FM disease duration, and the location of the tender points. Misdiagnoses of FM are harmful to patients and the community, and the presence of enthesopathy among FM patients increases. Its detection with the MASEI score may help to discriminate FM patients presenting with ill-defined symptoms and signs, in order to prevent mistreatment.

    An attempt was made to correct for the effects of coagulometers on the International Sensitivity Index (ISI) in a series of collaborative studies. Modified ISI were derived from the prothrombin time results with coagulometer systems using a range of calibrated plasmas. Two alternative approaches to correction of the ISI were evaluated. The first relied on the consensus orthogonal regression slopes of the prothrombin times for each coagulometer system plotted against the consensus manual results; the second depended on the local individual slope of the prothrombin times for each instrument. The two procedures were compared with the currently recommended method where International Normalised Ratios (INR) are derived from the manual ISI of the thromboplastin. The recommended method gave a significant bias from the manual results with most coagulometers. In contrast, the local correction procedure gave no significant biases, whereas the consensus method did so in a few instances. Both these correction procedures seem more reliable than the recommended method of INR derivation, but the local correction is more accurate and offers a more practical solution by allowing laboratories to determine their own corrected ISI on a range of calibrated plasmas.

  19. Assessing the Added Value of Dynamical Downscaling Using the Standardized Precipitation Index

    2016-01-01

    Full Text Available In this study, the Standardized Precipitation Index (SPI is used to ascertain the added value of dynamical downscaling over the contiguous United States. WRF is used as a regional climate model (RCM to dynamically downscale reanalysis fields to compare values of SPI over drought timescales that have implications for agriculture and water resources planning. The regional climate generated by WRF has the largest improvement over reanalysis for SPI correlation with observations as the drought timescale increases. This suggests that dynamically downscaled fields may be more reliable than larger-scale fields for water resource applications (e.g., water storage within reservoirs. WRF improves the timing and intensity of moderate to extreme wet and dry periods, even in regions with homogenous terrain. This study also examines changes in SPI from the extreme drought of 1988 and three “drought busting” tropical storms. Each of those events illustrates the importance of using downscaling to resolve the spatial extent of droughts. The analysis of the “drought busting” tropical storms demonstrates that while the impact of these storms on ending prolonged droughts is improved by the RCM relative to the reanalysis, it remains underestimated. These results illustrate the importance and some limitations of using RCMs to project drought.

    The circumstances under which the glycemic index (GI) and glycemic load (GL) are derived do not reflect real-world eating behavior. Thus, the ecologic validity of these constructs is incompletely known. This study examined the relation of dietary intake to glycemic response when foods are consumed under free-living conditions. Participants were 26 overweight or obese adults with type 2 diabetes who participated in a randomized trial of lifestyle modification. The current study includes baseline data, before initiation of the intervention. Participants wore a continuous glucose monitor and simultaneously kept a food diary for 3 d. The dietary variables included GI, GL, and intakes of energy, fat, protein, carbohydrate, sugars, and fiber. The glycemic response variables included AUC, mean and SD of continuous glucose monitoring (CGM) values, percentage of CGM values in euglycemic and hyperglycemic ranges, and mean amplitude of glycemic excursions. Relations between daily dietary intake and glycemic outcomes were examined. Data were available from 41 d of monitoring. Partial correlations, controlled for energy intake, indicated that GI or GL was significantly associated with each glycemic response outcome. In multivariate analyses, dietary GI accounted for 10% to 18% of the variance in each glycemic variable, independent of energy and carbohydrate intakes (P glycemic stability and variability.

    Full Text Available In the last decades, pesticides have been used extensively, in order to control pests and plant diseases, but negative impacts of pesticides caused several environmental problems and put human health in danger. In order to decrease environmental hazards of pesticide, risk of pesticide application should be measured briefly and precisely. In this study environmental impacts of registered insecticides in Iran which applied in 2001-2002, 2003-2004, 2004-2005, are considered using environmental impact quotient (EIQ index. Results showed that among considered insecticides, Imidacloprid, Fipronil and Tiodicarb, potentially (EIQ were the most hazardous insecticides, respectively. Taking rate of application and active ingredient of insecticide in to account, environmental impact (practical toxicity per cultivated hectare (EIQ Field of each provinces were investigated. In this regard, among different province of Iran, Kerman, Mazandaran and Golestan were in danger more than the others, respectively. Besides, considering the amount of agricultural production in provinces, environmental impact per ton of production were calculated for each provinces which three northern provinces of Mazandaran, Golestan and Guilan, respectively endure the most environmental impact per ton of production. Eventually based on environmental impact quotient, results demonstrated that majority of environmental impacts of insecticide in Iran were due to inadequate knowledge and also overuse of a few number of insecticides. Therefore, by improving knowledge about environmental impact of pesticides and also developing environmental friendly and ecological based methods, negative environmental impacts of insecticides will be reduced significantly.

    In a cross-sectional design, the sensitivity and specificity of the Quetelet Index (QI) was determined in relation to percent body fat standards. Subjects were 1280 men and 365 women asymptomatic for coronary heart disease. Contingency tables by QI quartiles were created using two sets of criteria of obesity: body fat > or = 25% and QI > or = 28 kg.m-2 for men and 30% and 27 kg.m-2 for women. Percent body fat was determined with hydrodensitometry in all subjects. In men, sensitivity, positive, and negative predictive value of QI in relation to percent body fat was 54.5%, 91.8%, 82.7% and 73.8%, respectively. The corresponding values for women were 26.9%, 98.2%, 90.7% and 67.1%. Sensitivity of QI was 2.03 times greater for men than for women (P < 0.001). Receiver operator characteristic (ROC) curve analysis suggested that an acceptable trade-off between sensitivity (91%) and specificity (47%) occurred at a QI of 24.5 kg.m-2 for men and at a QI of 22 kg.m-2 for women. The data suggest that in an asymptomatic population, percent body fat-based QI cut-off values may misclassify the obese. A fat mass-based reference system could perhaps lead to an improved classification outcome.

    Overweight and obesity are increasing at an alarming rate among older people. This is mainly because this population is predominantly sedentary. The aim of this study was to classify, according to the body mass index (BMI), a group of older active women and to evaluate the different basic physical abilities as a function of this. The BMI and fitness were evaluated in 60 elderly active women (mean age: 66.14 ± 6.59 years) using the 2-minute step test, arm curl test, chair stand test, back scratch test, chair-sit and reach-test, flamenco test, and 8-foot up-and-go test. It was found that 52.23% of the women studied had a normal BMI and 47.76% were slightly overweight. There were no cases of obesity or underweight. Women with normal BMI had better values in all tests than overweight women. Significant differences were found in the flamenco test (P<.05), and 8-foot up-and-go test (P<.01). Older women who usually do physical activity had a normal or slightly overweight BMI. It was also found that women with lower BMI have better resistance, flexibility, balance and strength.

    Fetal cardiac left ventricular function in pregnant women with pregestational or gestational diabetes mellitus was investigated by exploring fetal myocardial performance index (MPI) and E wave/A wave peak velocity (E/A) ratio. Seventy pregnant women with either pregestational or gestational diabetes mellitus and with no other systemic or pregnancy related disorders were compared with 70 gestational age matched healthy controls by means of fetal left ventricular MPI and E/A ratio. Opening and closing clicks of the mitral and aortic valves were used to define the three time periods: ejection time (ET), isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT), which were employed in the calculation of MPI (MPI = [ICT + IRT]/ET). Statistical analyses were conducted using receiver operating characteristic analysis and independent two-sample t, Mann-Whitney U and chi-square tests. Fetal left ventricular MPI values were significantly higher in the diabetic group compared with controls (0.56 ± 0.09 vs 0.36 ± 0.04, P diabetic group. Receiver operating characteristic analysis revealed > 0.39 as the optimal cut-off level for MPI in perinatal adverse outcome prediction (sensitivity: 90.9%, specificity: 47.7%, area under the curve: 0.690, 95% confidence interval: 0.598-0.782, P diabetic mothers have significant left ventricular systolic and diastolic dysfunction. MPI may be used in the prediction of adverse perinatal outcome in diabetic pregnancies. © 2016 Japan Society of Obstetrics and Gynecology.

    The structural similarity index (SSIM) family is a set of metrics that has demonstrated good agreement with human observers in tasks using reference images. These metrics analyze the viewing distance, edge information between the reference and the test images, changed and preserved edges, textures, and structural similarity of the images. Eight metrics based on that family are proposed. This new set of metrics, together with another eight well-known SSIM family metrics, was tested to predict human performance in some specific tasks closely related to the evaluation of radiological medical images. We used a database of radiological images, comprising different acquisition techniques (MRI and plain films). This database was distorted with different types of distortions (Gaussian blur, noise, etc.) and different levels of degradation. These images were analyzed by a board of radiologists with a double-stimulus methodology, and their results were compared with those obtained from the 16 metrics analyzed and proposed in this research. Our experimental results showed that the readings of human observers were sensitive to the changes and preservation of the edge information between the reference and test images, changes and preservation in the texture, structural component of the images, and simulation of multiple viewing distances. These results showed that several metrics that apply this multifactorial approach (4-G-SSIM, 4-MS-G-SSIM, [Formula: see text], and [Formula: see text]) can be used as good surrogates of a radiologist to analyze the medical quality of an image in an environment with a reference image.

    The demands and needs of the community will be the quality of public services in Malang increased, so that the Government of Malang as organizers and executors of public services must meet these demands. The Municipal Government in its efforts to improve public service performance, forming the regional One Stop Operator (PPTSP) with the goal will be to simplify and improve efficiency in administrative proceedings. But the existence of the one stop service is still not optimal because of the persistence of public complaints about the performance of the one stop service. This study will discuss the performance of services in service counter of Population and Civil Registration through community satisfaction index to measure the service level and the perception of satisfaction and interest to determine which variables are less optimal and need to be improved using IPA method. The results showed that the level of service at the service counter of Population and Civil Registration quite good. Meanwhile, according the results of IPA analysis, there are two important variables for the community on the performance / quality was lacking, namely the service procedure and time.

    A novel quantitative volumetric spreading index (VSI) is defined that depends on the total distance between object voxels and the contact surface plane in three-dimensional (3D) space. The VSI, which ranges from 0 to 1, is rotationally invariant around the z-axis. VSI can be used to quantify the degree of individual cell spreading, which is important for analysis of cell interactions with their environment. The VSIs of astrocytes cultured on a nanofibrillar surface and three different comparative planar surfaces have been calculated from confocal laser scanning microscope z-series images, and the effects of both culture surface and immunoreactivity on the degree of cell spreading were investigated. VSI calculations indicated a statistical correlation between increased reactivity, based on immunolabeling for glial fibrillary acidic protein, and decreased cell spreading. Further results provided a quantitative measure for the increased spreading of quiescent-like and reactive-like astrocytes on planar substrates functionalized with poly-l-lysine. © 2017 International Society for Advancement of Cytometry. © 2017 International Society for Advancement of Cytometry.

    2016-01-01

    Full Text Available Construction projects are risky in both physical implementation and management. The characteristics of the risk reinforce the necessity of efficient management to increase the chances of success without commitment to its goals. This study explores the correlation of delay and the schedule performance index (SPI to evaluate the risk of a construction project completed with time overruns. The hypothesis that the SPI of projects with a delay is distinct from those projects without a delay is assumed. A database with 19 elements was used to test this hypothesis and to calculate limit values to the SPI. Therefore, the risk of delay will be small when the observed SPI is greater than the superior limit and large when the SPI is below the inferior limit. The simplicity involved in the calculation of these values showed an advantage in comparison with other methods of risk evaluation. Another strong point observed is that any company can determine the value of risk by considering its own history and support decisions like doing corrective actions.

  11. Blended Drought Index: Integrated Drought Hazard Assessment in the Cuvelai-Basin

    2017-07-01

    Full Text Available Drought is one of the major threats to societies in Sub-Saharan Africa, as the majority of the population highly depends on rain-fed subsistence agriculture and traditional water supply systems. Hot-spot areas of potential drought impact need to be identified to reduce risk and adapt a growing population to a changing environment. This paper presents the Blended Drought Index (BDI, an integrated tool for estimating the impact of drought as a climate-induced hazard in the semi-arid Cuvelai-Basin of Angola and Namibia. It incorporates meteorological and agricultural drought characteristics that impair the population’s ability to ensure food and water security. The BDI uses a copula function to combine common standardized drought indicators that describe precipitation, evapotranspiration, soil moisture and vegetation conditions. Satellite remote sensing products were processed to analyze drought frequency, severity and duration. As the primary result, an integrated drought hazard map was built to spatially depict drought hot-spots. Temporally, the BDI correlates well with millet/sorghum yield (r = 0.51 and local water consumption (r = −0.45 and outperforms conventional indicators. In the light of a drought’s multifaceted impact on society, the BDI is a simple and transferable tool to identify areas highly threatened by drought in an integrated manner.

    Concentration of fecal nitrogen has been used widely as an indicator of dietary quality for free-ranging ruminants. Differences in digestive function between species of dimorphic ungulates render interspecific comparisons of fecal nitrogen unreliable; however, whether intraspecific sexual differences in digestive function also bias this nutritional index is unknown. Our objective was to compare sex-specific variation in concentration of fecal nitrogen using male, nonlactating female, and lactating female white-tailed deer (Odocoileus virginianus) on high- and low-quality diets. During weekly trials over spring and summer (2008-2009), we monitored intake rates, collected feces twice daily, and used micro-Kjeldahl procedures to determine percent fecal nitrogen. We also determined nitrogen content of feces following a neutral detergent fiber (NDF) rinse during pre-, peak, and postlactation. Fecal nitrogen reflected general differences in dietary quality between diets; however, fecal nitrogen of lactating females in both dietary groups was lower than for males or nonlactating females throughout lactation. Nitrogen concentration following an NDF rinse also was lower for lactating females during peak lactation. We hypothesize that the remodeling of the digestive tract and increased rumination by lactating females may enhance their ability to extract nitrogen from their forage. These adjustments may expand the foraging options of lactating females by increasing their ability to process low-quality foods, but also affects the interpretation of fecal nitrogen during the season of lactation.

    A comprehensive quantitative assessment of the lands based on their agricultural efficiency is required for successful cultivation of crops and effective land management. In order to assessment and ranking of soils, various indexes taking into account edaphic and climatic conditions are applied. One of these indicators is soil-environmental index (SEI) assessing agroecological potential of lands. Forest-steppe soils of the East European Plain are characterized by high fertility and are used for the cultivation of winter wheat, sunflower, sugar beet, etc. However, agricultural ranking of these areas has still not been carried out. The aim of this study was to determine soil-environmental index values for the East European Plain soils within the administrative subjects of Russian Federation, and to test its applicability in agriculture. The study was carried out for the forest-steppe area of East European Plain within the boundaries of Central Russian natural and agricultural province (18 administrative subjects of Russian Federation). SEI of lands was calculated using Karmanov's equation. This equation takes into account three constituent elements: climatic conditions (the sum of temperatures above 10 ⁰C, humidity and continentality coefficients), agrophysical (particle size distribution, soil density) and agrochemical (total organic carbon, mobile phosphorus and potassium content) properties of soils. Agrophysical, agrochemical and climate data from the long-term observations were used. Data visualization was performed by QGIS and SAGA software. SEI clearly reflected the changes in edaphic and climatic conditions. Moreover, SEI correlated with summer and winter wheat yields (R2 = 0.69). For the western part of province, SEI ranked by regions, ranged from 49.4 to 84.0. These significant differences can be explained by gradual increasing of averaged temperatures in southern regions compared with northern, as well as by considerable shifts in soil types distribution

    Full Text Available During the past decade, the construction industry has seen a new trend in the development of “green” or “sustainable” construction concept around the world with vast support from prominent organization, together with the introduction of sustainable building codes. The establishment of green building certification systems worldwide is seen as one of the most efforts in the emerging green building movement. In order to support the development of the “green” and “sustainable” concept in Malaysia, Green Building Index (GBI was launched by the government on 21 May 2009 that created to promote sustainability in the built environment and raise awareness of environmental issues. However, the construction industry seems to have focused only on findings the “right mechanism” for an environmentally sustainable “final result” in order for the building to be certified as green with the lacking of continuous assessment on the building performance after the certifications. This study is purposely conducted to investigate the performance of various rated Green Building Index (GBI Non-Residential New Construction office buildings and the influence on Indoor Thermal Comfort (ITC of the selected buildings. The aim is to develop an assessment framework for optimum green building architectural façade to be used for office buildings in Malaysia as well as to analyse the occupants’ perception, satisfaction and performance in the selected Green Building Index (GBI rated office indoor environment. This research is still in its infancy; therefore the paper is focused on research aims, research scope and methodology, and expected deliverables for the proposed research.

    The ability to quantitatively assess ecological health is of great interest to those tasked with monitoring and conserving ecosystems. For decades, biomonitoring research and policies have relied on multimetric health indices of various forms. Although indices are numbers, many are constructed based on qualitative procedures, thus limiting the quantitative rigor of the practical interpretations of such indices. The statistical modeling approach to construct the latent health factor index (LHFI) was recently developed. With ecological data that otherwise are used to construct conventional multimetric indices, the LHFI framework expresses such data in a rigorous quantitative model, integrating qualitative features of ecosystem health and preconceived ecological relationships among such features. This hierarchical modeling approach allows unified statistical inference of health for observed sites (along with prediction of health for partially observed sites, if desired) and of the relevance of ecological drivers, all accompanied by formal uncertainty statements from a single, integrated analysis. Thus far, the LHFI approach has been demonstrated and validated in a freshwater context. We adapt this approach to modeling estuarine health, and illustrate it on the previously unassessed system in Richibucto in New Brunswick, Canada, where active oyster farming is a potential stressor through its effects on sediment properties. Field data correspond to health metrics that constitute the popular AZTI marine biotic index and the infaunal trophic index, as well as abiotic predictors preconceived to influence biota. Our paper is the first to construct a scientifically sensible model that rigorously identifies the collective explanatory capacity of salinity, distance downstream, channel depth, and silt-clay content-all regarded a priori as qualitatively important abiotic drivers-towards site health in the Richibucto ecosystem. This suggests the potential effectiveness of the

    2014-10-01

    Full Text Available Land degradation and desertification has been ranked as a major environmental and social issue for the coming decades. Thus, the observation and early detection of degradation is a primary objective for a number of scientific and policy organisations, with remote sensing methods being a candidate choice for the development of monitoring systems. This paper reviews the statistical and ecological frameworks of assessing land degradation and desertification using vegetation index data. The development of multi-temporal analysis as a desertification assessment technique is reviewed, with a focus on how current practice has been shaped by controversy and dispute within the literature. The statistical techniques commonly employed are examined from both a statistical as well as ecological point of view, and recommendations are made for future research directions. The scientific requirements for degradation and desertification monitoring systems identified here are: (I the validation of methodologies in a robust and comparable manner; and (II the detection of degradation at minor intensities and magnitudes. It is also established that the multi-temporal analysis of vegetation index data can provide a sophisticated measure of ecosystem health and variation, and that, over the last 30 years, considerable progress has been made in the respective research.

    The "bioeffect assessment index" (BAI) is based on the integration of several pathological endpoints measured in the liver of European flounder (Platichthys flesus (L.)) during a long term study of biological effects of pollution in the German Bight. The BAI represents a modification of the "health assessment index" since it includes solely validated biomarkers reflecting toxically induced alterations at different levels of biological organisation in order to quantify the effects of environmental pollution. The concept of the BAI is based on the observation of progressive deleterious effects from early responses to late effects. Specific "key events" were detected, representing progressive stages of functional deterioration. The biomarkers selected from a whole battery of cellular markers for the BAI calculation reflect deleterious effects of various classes of contaminants such as heavy metals, organochlorines, pesticides, PAHs, and therefore reflect general toxicity in an integrative manner. Selected biomarkers were: lysosomal perturbations (reduced membrane stability), storage disorders (lipid accumulation) as early markers for toxic effects of liver cells, and the size of macrophage aggregates and their acid phosphatase activity. The latter two markers are indicative for the modulation of non-specific immune response which represents longer time scale responses after chronic exposure.

    The vulnerability of cities and communities in the Amazon to flooding and flash flooding is increasing. The effects of extreme events on populations vary across landscapes, causing vulnerability to differ spatially. Traditional vulnerability studies in Brazil and across the world have used the vulnerability index for the country and, more recently, municipality scales. The vulnerability dimensions are exposure, sensitivity, and adaptive capacity. For each of these dimensions, there is a group of indicators that constitutes a vulnerability index using quantitative data. Several vulnerability assessments have used sensitivity and exposure analyses and, recently, adaptive capacity has been considered. The Geographical Information Systems (GIS) analysis allows spatial regional modeling using quantitative vulnerability indicators. This paper presents a local-scale vulnerability assessment in an urban Amazonian area, Santarém City, using interdisciplinary methods. Data for exposure and sensitivity were gathered by remote sensing and census data, respectively. However, adaptive capacity refers to local capacities, whether infrastructural or not, and the latter were gathered by qualitative participatory methods. For the mixed data used to study adaptive capacity, we consider tangible components for countable infrastructure that can cope with hazards, and intangible components that reflect social activities based on risk perceptions and collective action. The results indicate that over 80% of the area is highly or moderately vulnerable to flooding and flash flooding. Exposure and adaptive capacity were determinants of the results. Lower values of adaptive capacity play a significant role in vulnerability enhancement. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available Dietary indices evaluate diet quality, usually based on current dietary guidelines. Indices can therefore contribute to our understanding of early-life obesity-risk dietary behaviours. Yet indices are commonly applied to dietary data collected by onerous methods (e.g., recalls or records. Short dietary assessment instruments are an attractive alternative to collect data from which to derive an index score. A systematic review of studies published before April 2013 was conducted to identify short (≤50 items tools that measure whole-of-diet intake of young children (birth-five years and are applicable to dietary indices, in particular screening obesogenic dietary behaviours. The search identified 3686 papers of which 16, reporting on 15 tools (n=7, infants and toddlers birth-24 months; n=8, preschoolers 2–5 years, met the inclusion criteria. Most tools were food frequency questionnaires (n=14, with one innovative dietary questionnaire identified. Seven were tested for validity or reliability, and one was tested for both. Six tools (n=2, infants and toddlers; n=4, preschoolers are applicable for use with current dietary indices, five of which screen obesogenic dietary behaviours. Given the limited number of brief, valid and reliable dietary assessment tools for young children to which an index can be applied, future short tool development is warranted, particularly for screening obesogenic dietary behaviours.

    Climate change threatens biodiversity globally, yet it can be challenging to predict which species may be most vulnerable. Given the scope of the problem, it is imperative to rapidly assess vulnerability and identify actions to decrease risk. Although a variety of tools have been developed to assess climate change vulnerability, few have been evaluated with regard to their suitability for certain taxonomic groups. Due to their ectothermic physiology, low vagility, and strong association with temporary wetlands, reptiles and amphibians may be particularly vulnerable relative to other groups. Here, we evaluate use of the NatureServe Climate Change Vulnerability Index (CCVI) to assess a large suite of herpetofauna from the Sand Hills Ecoregion of the southeastern United States. Although data were frequently lacking for certain variables (e.g., phenological response to climate change, genetic variation), sufficient data were available to evaluate all 117 species. Sensitivity analyses indicated that results were highly dependent on size of assessment area and climate scenario selection. In addition, several ecological traits common in, but relatively unique to, herpetofauna are likely to contribute to their vulnerability and need special consideration during the scoring process. Despite some limitations, the NatureServe CCVI was a useful tool for screening large numbers of reptile and amphibian species. We provide general recommendations as to how the CCVI tool's application to herpetofauna can be improved through more specific guidance to the user regarding how to incorporate unique physiological and behavioral traits into scoring existing sensitivity factors and through modification to the assessment tool itself.

    Climate change threatens biodiversity globally, yet it can be challenging to predict which species may be most vulnerable. Given the scope of the problem, it is imperative to rapidly assess vulnerability and identify actions to decrease risk. Although a variety of tools have been developed to assess climate change vulnerability, few have been evaluated with regard to their suitability for certain taxonomic groups. Due to their ectothermic physiology, low vagility, and strong association with temporary wetlands, reptiles and amphibians may be particularly vulnerable relative to other groups. Here, we evaluate use of the NatureServe Climate Change Vulnerability Index (CCVI) to assess a large suite of herpetofauna from the Sand Hills Ecoregion of the southeastern United States. Although data were frequently lacking for certain variables (e.g., phenological response to climate change, genetic variation), sufficient data were available to evaluate all 117 species.

    Aortic augmentation index (AIx) measured using applanation tonometry is a non-invasive indicator of arterial stiffness. The objective of this study was to assess its repeatability when used by nurses with limited experience of the technique. Blood pressure/augmentation index (BP/AIx) was measured 4 times in 20 consecutive ambulant patients (16 male) after they rested supine for 15 min. Two nurses independently and alternately measured BP/AIx using the same equipment (Omron HEM-757; SphygmoCor with Millar hand-held tonometer). Nurses were blinded to patient medical records and their colleague's AIx/BP. 'Within' and 'between' observer differences were assessed using intra-class correlation coefficients (rI) and 95 % limits of agreement (95 % LoA) derived from Bland-Altman plots. Mean age was 56 (mean BP 136/79; mean pulse 64). Mean AIx was 24.1 (range 2.8 to 41.0). Both 'between' and 'within' observer repeatability was very high, with intra-class correlation coefficients ranging from 0.92 to 0.98. Mean AIx readings 'between' observers differed by only 0.68 (95 % CI -0.24 to 1.59) with a high rI (0.98; 95 % CI 0.95 to 0.99) and a narrow 95 % LoA (-3.22 to 4.57). The 95 % LoA for 'within' observer repeatability was -6.75 to 7.95. Differences in AIx measurement did not vary over time or with increasing levels of AIx. Even when undertaken by relatively inexperienced operators, both 'within' and 'between' observer repeatability of AIx measurement is very high. Such non-invasive assessment of arterial stiffness has the potential to be included in the clinical assessment of ambulant patients.

    To present user needs and usability evaluations of DataMed, a Data Discovery Index (DDI) that allows searching for biomedical data from multiple sources. We conducted 2 phases of user studies. Phase 1 was a user needs analysis conducted before the development of DataMed, consisting of interviews with researchers. Phase 2 involved iterative usability evaluations of DataMed prototypes. We analyzed data qualitatively to document researchers' information and user interface needs. Biomedical researchers' information needs in data discovery are complex, multidimensional, and shaped by their context, domain knowledge, and technical experience. User needs analyses validate the need for a DDI, while usability evaluations of DataMed show that even though aggregating metadata into a common search engine and applying traditional information retrieval tools are promising first steps, there remain challenges for DataMed due to incomplete metadata and the complexity of data discovery. Biomedical data poses distinct problems for search when compared to websites or publications. Making data available is not enough to facilitate biomedical data discovery: new retrieval techniques and user interfaces are necessary for dataset exploration. Consistent, complete, and high-quality metadata are vital to enable this process. While available data and researchers' information needs are complex and heterogeneous, a successful DDI must meet those needs and fit into the processes of biomedical researchers. Research directions include formalizing researchers' information needs, standardizing overviews of data to facilitate relevance judgments, implementing user interfaces for concept-based searching, and developing evaluation methods for open-ended discovery systems such as DDIs.

    To develop and validate a concise survey that will identify athletes who possess elevated injury risk. Cohort study. National Collegiate Athletic Association Division I athletic program. Cohorts of 188 and 146 college athletes who participated during successive academic years. The first cohort provided responses to 4 joint-specific outcome surveys that were related to subsequent time-loss injury occurrence. Receiver operating characteristic analysis identified survey items that provided best discrimination, which were combined with a negative life event stress item to create a new 10-item survey. The second cohort provided responses to the new survey, which were converted to a 0 to 100 score. Construct validity was assessed through documentation of time-loss injuries sustained during the preceding 12 months and predictive validity was assessed through prospective documentation of sport-related sprains and strains. Cronbach alpha was calculated to assess internal consistency. Each of the outcome survey items used to develop the new survey demonstrated much greater specificity than sensitivity. Both the retrospective and prospective receiver operating characteristic (ROC) analyses identified scores of 96 and 88 as cut-points that provided good discrimination between injured and noninjured cases. The area under the curve was 0.69 (P alpha was 0.89 (90% CI, 0.86-0.91). Self-reported effects of previous injury may be one method to efficiently identify athletes who possess elevated injury risk, and subsequently deliver preventive interventions, thereby providing an alternative method to time-intensive functional testing.

    We assessed the effect of weight loss-associated changes in detailed body composition on plasma insulin levels and homeostatic model assessment (HOMA) index to calculate the magnitude of reduction in different adipose tissue depots required to improve insulin sensitivity. A total of 50 subjects aged 20-69 years were studied. The participants were compiled from low-calorie diet interventions and bariatric surgery and differed in their baseline body mass index (BMI; range 21.6-54.4 kg/m2) and degree of weight losses (range -3.3 to -56.9 kg). Detailed body composition and liver fat were measured using whole-body magnetic resonance imaging (MRI). Insulin resistance was assessed by HOMA. Mean body weight decreased by -16.0±13.6 kg. Significant changes were observed in total adipose tissue (TATMRI, range -0.5 to -36.0 kg), total subcutaneous adipose tissue (SATMRI), visceral adipose tissue (VATMRI), skeletal muscle, liver fat, plasma insulin levels and HOMA. Decreases in insulin and HOMA were correlated with reductions in TATMRI, SATMRI, VATMRI (just with HOMA) and liver fat. Losses of 2.9 and 6.5 kg body weight, 2.0 and 5.0 kg TATMRI as well as 1.6 and 6% liver fat were required to decrease plasma insulin levels by 1 μU/ml and HOMAadjusted for baseline HOMA by 1 point. Multiple regression analysis showed that baseline liver fat and changes in liver fat explained 49.7% and 55.1% of the variance in weight loss-associated changes in plasma insulin and HOMA, respectively. Decreases of adipose tissues and liver fat are the major determinants of reduction in plasma insulin levels and improvement in HOMA index.

  10. Green Plants in the Red: A Baseline Global Assessment for the IUCN Sampled Red List Index for Plants.

    Directory of Open Access Journals (Sweden)

    Neil A Brummitt

    Full Text Available Plants provide fundamental support systems for life on Earth and are the basis for all terrestrial ecosystems; a decline in plant diversity will be detrimental to all other groups of organisms including humans. Decline in plant diversity has been hard to quantify, due to the huge numbers of known and yet to be discovered species and the lack of an adequate baseline assessment of extinction risk against which to track changes. The biodiversity of many remote parts of the world remains poorly known, and the rate of new assessments of extinction risk for individual plant species approximates the rate at which new plant species are described. Thus the question 'How threatened are plants?' is still very difficult to answer accurately. While completing assessments for each species of plant remains a distant prospect, by assessing a randomly selected sample of species the Sampled Red List Index for Plants gives, for the first time, an accurate view of how threatened plants are across the world. It represents the first key phase of ongoing efforts to monitor the status of the world's plants. More than 20% of plant species assessed are threatened with extinction, and the habitat with the most threatened species is overwhelmingly tropical rain forest, where the greatest threat to plants is anthropogenic habitat conversion, for arable and livestock agriculture, and harvesting of natural resources. Gymnosperms (e.g. conifers and cycads are the most threatened group, while a third of plant species included in this study have yet to receive an assessment or are so poorly known that we cannot yet ascertain whether they are threatened or not. This study provides a baseline assessment from which trends in the status of plant biodiversity can be measured and periodically reassessed.

    Climate change is expected to impact the water cycle through changing the precipitation levels, river streamflows, soil moisture dynamics and therefore pose a threat to groundwater and surface-water fed wetlands and their biodiversity. We examined the past trends and future impacts of climate change on streamflow and soil water content. Simulation results from 1971 to 2000 (historical period) and from 2021 to 2100 (future period) were obtained with the use of the Soil and Water Assessment Tool (SWAT). Hydrological modelling was driven by a set of nine EUROCORDEX Regional Climate Models under two Representative Concentration Pathways (RCP's) of greenhouse gas concentration trajectories: 4.5 and 8.5. A special focus was made on water dependent habitats within the Special Areas of Conservation (SAC's) of the Natura 2000 network located within Odra and Vistula River basins in Poland. A habitat assessment was carried out to distinguish groundwater and surface water fed wetlands. By establishing threshold values of streamflow at bankfull flow we were able to identify flood events. Changes in frequency of the floods informed about the alteration to the water supply for wetlands reliant on inundation. The groundwater-fed wetlands were assessed on the basis of the soil water content. The model outputs were used to develop indices which were calculated for the climate change scenarios. Comparisons of simulated trends in soil water content and streamflow dynamics with average annual precipitation showed largely consistent patterns. The developed indicators are sensitive to projected changes in hydrologic regime in the conditions of changing climate. The results show influence of climate change on floodplain and groundwater-fed wetlands and show the number and kind of wetlands threatened in different regions of Poland. SAC's will play an important role of buffers and water regulators as soil water content in SAC's is projected to be higher than average for the future scenarios.

    Recently, a new anthropometric parameter (a new hip index [HI]) was developed, and the HI shows a U-shaped relationship to mortality in the USA population. It is well known that there is an inverse relationship between hip circumference (HC) and the risk of diabetes mellitus. Accordingly, the study sought to investigate whether HI could predict future diabetes mellitus, as compared with HC and the waist-to-hip ratio (WHR), in a general Chinese population. In 2007, we carried out a health examination of 687 participants (mean age 48.1 ± 6.2 years, male 58.1%). Development of diabetes mellitus by the 2007 examination was studied in relation to data from a baseline health examination carried out in 1992. During the follow up, 74 participants were diagnosed with diabetes mellitus. Across the quintiles of baseline HI, the incidence rates of diabetes mellitus were 12.4, 12.4, 9.9, 7.8 and 11.3% in quintile (Q)1, Q2, Q3, Q4 and Q5, respectively (P = 0.698). With the lowest quintile (Q1) as reference, univariate and multivariate Cox regression analyses showed that HI was not associated with diabetes mellitus. In contrast, HC and WHR could predict future diabetes mellitus. Furthermore, WHR had the best discriminatory power for diabetes mellitus (area under the receiver operating characteristic curve 0.691, 95% confidence interval 0.621-0.761), followed by HC (area under the receiver operating characteristic curve 0.623, 95% confidence interval 0.558-0.689) and HI (area under the receiver operating characteristic curve 0.464, 95% confidence interval 0.396-0.531). Compared with HC and WHR, HI was not an independent risk factor for diabetes mellitus in the Chinese population. More studies are required to delineate the limits of the utility of HI. © 2017 The Authors.

    Tools for assessing and communicating salt marsh condition are essential to guide decisions aimed at maintaining or restoring ecosystem integrity and services. Multimetric indices (MMIs) are increasingly used to provide integrated assessments of ecosystem condition. We employed a theory-based approach that considers the multivariate relationship of metrics with human disturbance to construct a salt marsh MMI for five National Parks in the northeastern USA. We quantified the degree of human disturbance for each marsh using the first principal component score from a principal components analysis of physical, chemical, and land use stressors. We then applied a metric selection algorithm to different combinations of about 45 vegetation and nekton metrics (e.g., species abundance, species richness, and ecological and functional classifications) derived from multi-year monitoring data. While MMIs derived from nekton or vegetation metrics alone were strongly correlated with human disturbance (r values from −0.80 to −0.93), an MMI derived from both vegetation and nekton metrics yielded an exceptionally strong correlation with disturbance (r = −0.96). Individual MMIs included from one to five metrics. The metric-assembly algorithm yielded parsimonious MMIs that exhibit the greatest possible correlations with disturbance in a way that is objective, efficient, and reproducible.

    2015-01-01

    Obesity is a problem of serious concern among chronic kidney disease (CKD) patients; it is a risk factor for progression to end-stage renal disease and its incidence and prevalence in dialysis patients exceeds those of the general population. Obesity, typically assessed with the simple metric of body mass index (BMI), is considered a mainstay for nutritional assessment in guidelines on nutrition in CKD. While regular BMI assessment in connection with the dialysis session is a simple and easy-to-use monitoring tool, such ease of access can lead to excess-of-use, as the value of this metric to health care professionals is overestimated. This review examines BMI as a clinical monitoring tool in CKD practice and offers a critical appraisal as to what a high or a low BMI may signify in this patient population. Topics discussed include the utility of BMI as a reflection of body size, body composition and body fat distribution, diagnostic versus prognostic performance, and consideration of temporal trends over single assessments. © 2014 Wiley Periodicals, Inc.

    Full Text Available Introduction: Drought is a recurrent feature of climate that caused by deficiency of precipitation over time. Due to the rise in water demand and alarming climate change, recent year’s observer much focus on drought and drought conditions. A multiple types of deficits and relevant temporal scales can be achieved through the construction of a joint indicator that draws on information from multiple sources and will therefore enable better assessment of drought characteristics including return period, persistent and severity. The Standardized Precipitation Evapotranspiration Index (SPEI combines information from precipitation and temperature in the form of water surplus or deficit according to Standardized Precipitation Index (SPI. Rainfall over some regions of Iran during some resent year was below average while mean and maximum temperatures were very high during this period, as was evaporation. This would suggest that drought conditions were worse than in previous recent periods with similarly low rainfall. The main objective of this study is to assess the influences of humidity on the SPEI index and investigate its relation with SPI and Reconnaissance Drought Index (RDI over six different climatic regions in Iran. Materials and Methods: Iran has different climatic conditions which vary from desert in central part to costal wet near the Caspian Sea. In this study the selection of stations was done based on Alijani et al (2008 climatic classification. We chose 11 synoptic stations from six different climatic classes including costal wet (Rasht and Babolsar, semi mountains (Mashhad and Tabriz, mountains (Shiraz and Khoram Abad, semi-arid (Tehran and Semnan, arid (Kerman and Yazd and costal desert (Bandar Abas. The Meteorological datasets for the aforementioned stations were obtained from the Iran Meteorological Organization (IRIMO for the period 1960-2010. The compiled data included average monthly values of precipitation, minimum and maximum air

    The concept of sustainability is central to smallholder agriculture as subsistence farming is constantly impacted by livelihood insecurity and is constrained by access to capital, water technology and alternative employment opportunities. This study compares two approaches which aim at quantifying smallholder sustainability but differ in their underlying principles, methodologies for assessment and reporting, and applications. The yield index based insurance can protect the smallholder agriculture and help it to more economic sustainability because the income of smallholder depends on selling crops and this insurance scheme is based on crop yields. In this research, the trigger of this insurance sets on the basis of yields in previous years. The crop yields are calculated every year through socio-hydrology modeling and smallholder can get indemnity when crop yields are lower than average of previous five years (a crop failure). The FAO Sustainability Assessment of Food and Agriculture (SAFA) is an inclusive and comprehensive framework for sustainability assessment in the food and agricultural sector. It follows the UN definition of the 4 dimensions of sustainability (good governance, environmental integrity, economic resilience and social well-being) and includes 21 themes and 58 sub-themes with a multi-indicator approach. The direct sustainability corresponding to the FAO SAFA economic resilience dimension is compared with the indirect notion of sustainability derived from the yield based index insurance. A semi-synthetic comparison is conducted to understand the differences in the underlying principles, methodologies and application of the two approaches. Both approaches are applied to data from smallholder regions of Marathwada in Maharashtra (India) which experienced a severe rise in farmer suicides in the 2000s which has been attributed to a combination of socio-hydrological factors.

    The present prospective study sought to draw up and validate a self-assessment questionnaire for disability following head and neck cancer treatment. The Carcinologic Handicap Index (CHI) was designed empirically based on the Voice Handicap Index. It comprises 9 dimensions, self-assessed by the patient: pain, swallowing, feeding, respiration, phonation, hearing, vision, olfaction-gustation, and psychosocial. For each dimension, 4 items are scored in terms of frequency, providing dimension and global scores. The CHI was tested on 86 head and neck cancer patients (pathologic group: male predominance; mean age, 59 years) and 18 control subjects, for validation. Global internal coherence was 0.905 (Cronbach alpha); content validity (r, between questionnaire scores and corresponding visual analog scales) ranged between 0.6 and 0.8 except for the vision dimension and for total score compared to general health rating on VAS (r≤0.5: i.e., the pathology did not directly impair vision and was only one factor among others affecting general health status); temporal validity was satisfactory (r>0.7; P<0.0001) except on the respiration dimension (r=0.624, probably due to fluctuation in pulmonary congestion). Impact on swallowing, feeding and respiration varied with lesion site. There were no significant differences between patients and controls on the pain, hearing and vision dimensions. The CHI showed acceptable psychometric qualities and can be considered as an authentic clinical tool for health professionals, assessing the impact of ENT pathology on quality of life, mainly in the functional domains directly affected by the pathology or treatment.

    Global climate change will influence environmental conditions including temperature, surface radiation, soil moisture, and sea level, and it will also significantly impact regional-scale hydrologic processes such as evapotranspiration (ET), precipitation, runoff, and snowmelt. The quantity and quality of water available for drinking and other domestic usage is also likely to be affected by changes in these processes. Consequently, it is necessary to assess and reflect upon the challenges ahead for water infrastructure and the general public in metropolitan regions. One approach to the problem is to use index-based assessment, forecasting and planning. The drought indices previously developed were not developed for domestic water supplies, and thus are insufficient for the purpose of such an assessment. This paper aims to propose and develop a "Metropolitan Water Availability Index (MWAI)" to assess the status of both the quantity and quality of available potable water sources diverted from the hydrologic cycle in a metropolitan region. In this approach, the accessible water may be expressed as volume per month or week (i.e., m(3)/month or m(3)/week) relative to a prescribed historical record, and such a trend analysis may result in final MWAI values ranging from -1 to +1 for regional water management decision making. The MWAI computation uses data and information from both historical point measurements and spatial remote-sensing based monitoring. Variables such as precipitation, river discharge, and water quality changes at drinking water plant intakes at specific locations are past "point" measurements in MWAI calculations. On the other hand, remote sensing provides information on both spatial and temporal distributions of key variables. Examples of remote-sensing images and sensor network technologies are in-situ sensor networks, ground-based radar, air-borne aircraft, and even space-borne satellites. A case study in Tampa Bay, Florida is described to demonstrate

    Cyclone, storm surge, coastal flooding, salinity intrusion, tornado, nor'wester, and thunderstorms are the listed natural hazards in the coastal areas of Bangladesh. Bangladesh was hit by devastating cyclones in 1970, 1991, 2007, 2009, and 2016. Intensity and frequency of natural hazards in the coastal area are likely to increase in future due to climate change. Risk assessment is one of the most important steps of disaster risk reduction. As a climate change victim nation, Bangladesh claims compensation from green climate fund. It also created its own climate funds. It is therefore very important to assess vulnerability of the coast of Bangladesh to natural hazards for efficient allocation of financial investment to support the national risk reduction. This study aims at identifying the spatial variations in factors contributing to vulnerability of the coastal inhabitants of Bangladesh to natural hazards. An exploratory factor analysis method has been used to assess the vulnerability at each local administrative unit. The 141 initially selected 141 socio-economic indicators were reduced to 41 by converting some of them to meaningful widely accepted indicators and removing highly correlated indicators. Principle component analysis further reduced 41 indicators to 13 dimensions which explained 79% of total variation. PCA dimensions show three types of characteristics of the people that may lead people towards vulnerability. They are (a) demographic, education and job opportunities, (b) access to basic needs and facilities, and (c) special needs people. Vulnerability maps of the study area has been prepared by weighted overlay of the dimensions. Study revealed that 29 and 8 percent of total coastal area are very high and high vulnerable to natural hazards respectively. These are distributed along sea boundary and major rivers. Comparison of this spatial distribution with the capacities to face disaster show that highly vulnerable areas are well covered by cyclone

    Full Text Available There is evidence that rapid weight gain during the first year of life is associated with being overweight later in life. Therefore, overweight tendencies need to be detected at an appropriate age, and suitable strategies need to be implemented for weight management to achieve optimal long-term health. The objective of this study was to investigate comparisons in BMI status and associated categories in male and female students over ten years in two phases, including 2008-2013 and 2009-2014. Weight and height data were collected to obtain BMI (Body Mass Index over ten years in two phases. The first phase occurred from 2008 to 2013, and the second phase occurred from 2009 to 2014 in a population of 10846 school children (Males: 6970, 64.3%, and females: 3875, 35.7% in Macau. Their ages ranged from 6 years old in 2008 to 11 years old in 2013. The same age range was observed in the second phase, i.e., 2009-2014. Statistical analyses included descriptive statistics, such as the mean, standard deviation, t-tests to determine gender differences (year-wise and a Chi square test for independence to determine the relationship between BMI (Underweight, Standard, Overweight and Obese and age groups. In the first phase (2008-2013, the findings indicated a higher BMI level among the male students than the female students across all age groups (2008 t = 5.24, 2009 t = 88.25, 2010 t = 11.32, 2011 t = 17.45, 2012 t = 19.70 and 2013 t = 19.92. In the second phase (2009-2014, a higher BMI level was found among the male students than the female students across all age groups (2009 t = 2.68, 2010 t = 2.886, 2011 t = 3.076, 2013 t = 4.228, and 2014 t = 2.405. The results of the two phases combined (2008 to 2014 and 2009 to 2014 revealed that male students in 2008 had a higher BMI level than their counterparts in 2009 in the two age categories (8 years t = 3.025 and 11 years t = 3.377. Female students in the second phase (2009-2014 showed a higher BMI level than their

    Fetal malnutrition (FM) has grave implications for the neonate and is reliably assessed by the CANSCORE which is time-consuming. Static skinfold thickness, a measure of adiposity, is a validated method of assessing malnutrition in older children. To establish if static skinfold measurements in neonates can serve as a reliable measure of FM. To compare static skinfold thickness measurements in neonates using the CANSCORE for the identification of FM. 252 consecutive term neonates delivered at University College Hospital, Ibadan, Nigeria had their CANSCOREs and static skinfold thickness measured within 24 hours of delivery. Using correlation and linear regression analysis, static skinfold thickness cut-off points for FM were determined using a reference CANSCORE of FM was 20.2% and 26.2% using the CANSCORE and the sum of five skinfold thickness measurements, respectively. The mean (SD) skinfold thicknesses were triceps 3.91 mm (0.74), biceps 2.84 mm (0.55), subscapular 3.79 mm (0.91), supra-iliac 2.64 mm (0.62), quadriceps 4.43 mm (1) and the sum of all measurements 17.61 mm (3.16). All the skinfold thickness measurements correlated significantly with the CANSCORE, but the sum of the five had the best correlation. The quadriceps had the highest specificity of 85.6% and lowest sensitivity of 54.9%, while the sum of all had a sensitivity of 66.7% and specificity of 84.0%. The sum of all five skinfold measurements might be a useful screening tool for FM in view of its objectivity, convenience and simplicity, but it is not sufficiently sensitive or specific to replace the CANSCORE in the identification of FM in neonates.

    Full Text Available The savannah regions of Northern Ghana are characterized by smallholder farming systems and high levels of poverty. Over the past two decades, communities in the regions have become more prone to climate and human-induced disasters in the form of annual floods and droughts. This study evaluates the degree and magnitude of vulnerability in four communities subjected to similar climate change induced flood events and propose intervention options. The study employs rural participatory research approaches in developing four vulnerability categories namely socio-economic, ecological, engineering and political; which were used to develop indicators that aided the calculation of total community vulnerability index for each community. The findings indicate that the state of a community's vulnerability to flood is a composite effect of the four vulnerability index categories which may act independently or concurrently to produce the net effect. Based on a synthesis of total vulnerability obtained in each community, Baleufili was found to be the least vulnerable to flood due to its high scores in engineering, socio-economic and political vulnerability indicators. Baleufili and Bankpama were the most ecologically vulnerable communities. The selection of vulnerability index categories and associated indicators were grounded in specific local peculiarities that evolved out of engagement with community stakeholders and expert knowledge of the socioecological landscape. Thus, the Total Community Vulnerability Assessment Framework (TCVAF provides an effective decision support for identifying communities’ vulnerability status and help to design both short and long term interventions options that are community specific as a way of enhancing their coping and adaptive capacity to disasters.

    The limited availability of comprehensive data for Persistence, Bioaccumulation and Toxicity (PBT) of chemicals is a serious hindrance to the assignment of compounds to the categories of PBT and vPvB; REACH regulation requires authorization for the use of such chemicals, and additionally plans for safer alternatives. In the context of screening and priority-setting tools for PBT-assessment, the cumulative PBT Index model, implemented in QSARINS (QSAR-INSUBRIA), new software tool for the development and validation of multiple linear regression QSAR models, offers a new holistic approach for the identification of chemicals with cumulative PBT properties directly from their molecular structure. In this study the Insubria PBT Index in QSARINS is applied to the screening and prioritization of various data sets, containing a large variety of chemicals of heterogeneous molecular structure, previously screened by various authors by different methods, for their potential PBT behavior. Particular attention is devoted to the model Applicability Domain, using different approaches such as Descriptor Range, Leverage, and Principal Component Analysis (PCA) of the modeling molecular descriptors, in order to discriminate between interpolated and extrapolated predictions. The results of this screening, which is based only on the molecular structure features and is not dependent on single threshold values for P, B and T, are compared with those obtained by the on-line US-EPA PBT Profiler. Good agreement between the various approaches is found, supporting the utility of a consensus approach in priority-setting studies. The main discrepancies are highlighted and commented on. Moreover, a priority list containing the most hazardous compounds identified in agreement between the two tools is drafted. The PBT Index, implemented in QSARINS, which was demonstrated to be a practical, precautionary and reliable screening tool for PBT-behavior directly from the molecular structure, can be

    Sleep duration has been associated with overweight individuals in many epidemiological studies; however, few studies have assessed sleep using objective methods. Our study was designed to evaluate the association between body mass index (BMI) and sleep duration measured by actigraphy (Acti), polysomnography (PSG) and the Pittsburgh sleep quality index questionnaire (PSQIO). Furthermore, we evaluated other biochemical and polysomnographic parameters. A representative sample of 1042 individuals from Sao Paulo, Brazil, including both genders (20-80 yrs), participated in our protocol. Weight and other anthropometric parameters were measured at the onset of the study. Sleep duration was calculated by Acti, PSG, and the PSQIQ. The population was sorted by sleep duration, body, slow wave sleep (SWS) and REM sleep (REMS) duration subsets. In addition, other biochemical and polysomnographic parameters were analyzed. Differences between population subsets were analyzed by one-way analysis of variance (ANOVA). Linear regression analysis was performed between sleep and anthropometric parameters. Shorter sleep duration was associated with higher BMI and waist and neck circumference when measured by Acti and PSG (psleep in normal-weight (BMI>18 and ⩽25) individuals (psleep duration Acti and higher BMI was present when apnea-hypopnea index (AHI) was less than 15 (p=0.049). Shorter REMS and SWS also were associated with higher BMI (psleep longer, have higher sleep efficiency and longer SWS and REMS than obese individuals (Acti, PSG; p=0.05). Sleep duration was negatively correlated with BMI (Acti, PSG; psleep, SWS, and REMS duration were associated with higher BMI, central adiposity measurements, and cardiovascular risk factors when measured by objective methods.

    Full Text Available OBJECTIVE: Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circumference and waist-to-height ratio (WHtR as outcomes. DESIGN: Cross-sectional assessment of all participants in the "PREvención con DIeta MEDiterránea" (PREDIMED trial. SUBJECTS: 7,447 participants (55-80 years, 57% women free of cardiovascular disease, but with either type 2 diabetes or ≥ 3 cardiovascular risk factors. Trained dietitians used both a validated 14-item questionnaire and a full-length validated 137-item food frequency questionnaire to assess dietary habits. Trained nurses measured weight, height and waist circumference. RESULTS: Strong inverse linear associations between the 14-item tool and all adiposity indexes were found. For a two-point increment in the 14-item score, the multivariable-adjusted differences in WHtR were -0.0066 (95% confidence interval, -0.0088 to -0.0049 for women and -0.0059 (-0.0079 to -0.0038 for men. The multivariable-adjusted odds ratio for a WHtR>0.6 in participants scoring ≥ 10 points versus ≤ 7 points was 0.68 (0.57 to 0.80 for women and 0.66 (0.54 to 0.80 for men.

    The purpose of this study is to evaluate repeatability coefficients of diffusion tensor indices to assess whether longitudinal changes in diffusion indices were true changes beyond the uncertainty for individual patients undergoing radiation therapy (RT). Twenty-two patients who had low-grade or benign tumors and were treated by partial brain radiation therapy (PBRT) participated in an IRB-approved MRI protocol. The diffusion tensor images in the patients were acquired pre-RT, week 3 during RT, at the end of RT, and 1, 6, and 18 months after RT. As a measure of uncertainty, repeatability coefficients (RC) of diffusion indices in the segmented cingulum, corpus callosum, and fornix were estimated by using test-retest diffusion tensor datasets from the National Biomedical Imaging Archive (NBIA) database. The upper and lower limits of the 95% confidence interval of the estimated RC from the test and retest data were used to evaluate whether the longitudinal percentage changes in diffusion indices in the segmented structures in the individual patients were beyond the uncertainty and thus could be considered as true radiation-induced changes. Diffusion indices in different white matter structures showed different uncertainty ranges. The estimated RC for fractional anisotropy (FA) ranged from 5.3% to 9.6%, for mean diffusivity (MD) from 2.2% to 6.8%, for axial diffusivity (AD) from 2.4% to 5.5%, and for radial diffusivity (RD) from 2.9% to 9.7%. Overall, 23% of the patients treated by RT had FA changes, 44% had MD changes, 50% had AD changes, and 50% had RD changes beyond the uncertainty ranges. In the fornix, 85.7% and 100% of the patients showed changes beyond the uncertainty range at 6 and 18 months after RT, demonstrating that radiation has a pronounced late effect on the fornix compared to other segmented structures. It is critical to determine reliability of a change observed in an individual patient for clinical decision making. Assessments of the repeatability and

    Full Text Available Drought is expected to increase in frequency and severity due to global warming, and its impacts on vegetation are typically extensively evaluated with climatic drought indices, such as multi-scalar Standardized Precipitation Evapotranspiration Index (SPEI. We analyzed the covariation between the SPEIs of various time scales and the anomalies of the normalized difference vegetation index (NDVI, from which the vegetation type-related optimal time scales were retrieved. The results indicated that the optimal time scales of needle-leaved forest, broadleaf forest and shrubland were between 10 and 12 months, which were considerably longer than the grassland, meadow and cultivated vegetation ones (2 to 4 months. When the optimal vegetation type-related time scales were used, the SPEI could better reflect the vegetation’s responses to water conditions, with the correlation coefficients between SPEIs and NDVI anomalies increased by 5.88% to 28.4%. We investigated the spatio-temporal characteristics of drought and quantified the different responses of vegetation growth to drought during the growing season (April–October. The results revealed that the frequency of drought has increased in the 21st century with the drying trend occurring in most of China. These results are useful for ecological assessments and adapting management steps to mitigate the impact of drought on vegetation. They are helpful to employ water resources more efficiently and reduce potential damage to human health caused by water shortages.

    2015-12-01

    Full Text Available In this study, the net balance of greenhouse gas (GHG emission and energy of wheat and maize production systems in two farms in Khuzestan province of Iran was assessed. The results showed that totally wheat farming is more efficient than maize farming in terms of energy and CO2-eq indexes. The total energy requirement for maize and wheat farming was 92560.24 MJ ha-1 and 39624.15 MJ ha-1, which caused the emission of 20191.47 and 7541.04 kg CO2-equivalent per hectare in maize and wheat farms respectively. Electricity, fertilizers and fuel were the most important pollutants of environment in terms of energy and gas emission in both farms. Theses inputs consumed 55.52, 22.62 and 6.44 % of total energy of maize and 47.32, 21.19 and 9.01 % of total energy of wheat farm and were responsible for the 88.60, 8.79 and 2.03 % of CO2-equivalent in maize and 86.54, 9.54 and 3.24 % of CO2-equivalent in wheat farms respectively. The results of this study also showed that the enhancement of 60.74 and 27.02 % in energy ratio and 46.06 and 27.87 % in CO2-eq index in maize and wheat farming can be expected using simple improving scenarios.

    Family members have the capacity to influence each other's health behaviours. This study examined whether there were associations in the objectively assessed physical activity and Body Mass Index (BMI) of mothers and fathers. Recruitment took place in Bristol (UK) during 2012/13. Participants were 272 pairs of parents (dyads) that wore an accelerometer for at least 500 min on 3 or more days. Parents provided demographic information and self-reported height and weight. Multi-variable linear and logistic regression models examined the relationships between parents' moderate-to-vigorous physical activity (MVPA) and BMI. MVPA minutes (r = 0.26, p < 0.001) and Body Mass Index (r = 0.20, p = 0.002) of parents were correlated. Logistic regression analysis showed that mothers were almost twice (OR 1.87, p < 0.05) as likely to be overweight or obese when fathers were. Linear regression models showed that at the weekend every 9 min of paternal MVPA was associated with 3 min of maternal MVPA (r = 0.34, p < 0.001). Both physical activity and BMI of parenting partners were associated. Since parents tend to share home environments and often perform activities together or as a family, then behavioural changes in one parent may have a ripple effect for other family members.

    Sources of pollution discharges and water quality samples at 27 stations in 2006 in the coastal waters of Hebei Province, western Bohai Sea, have been analyzed in this study. Pollutant loads from industrial sewages have shown stronger impact on the water environment than those from the general sewages. Analysis indicates that pollution of COD is mainly resulted from land-based point pollutant sources. For phosphate concentration, non-point source pollution from coastal ocean (fishing and harbor areas) plays an important role. To assess the water quality conditions, Organic Pollution Index and Eutrophication Index have been used to quantify the level of water pollution and eutrophication conditions. Results show that pollution was much heavier in the dry season than flood season in 2006. Based on COD and phosphate concentrations, results show that waters near Shahe River, Douhe River, Yanghe River, and Luanhe River were heavily polluted. Water quality in the Qinhuangdao area was better than those in the Tangshan and Cangzhou areas. Copyright © 2011 Elsevier Ltd. All rights reserved.

    A total no. of 16 mine water (underground and opencast coal mine pump discharges) samples were collected from East Bokaro coalfield during pre-monsoon, monsoon and post-monsoon seasons. The concentrations of Fe, Mn, Cu, Pb, Zn, Ni, As, Se, Al, Cd and Cr were determined using inductively coupled plasma mass spectrometry for the assessment of spatio-temporal variations, source apportionment and heavy metal pollution indexing. The results demonstrated that concentrations of the metals showed significant seasonality and most variables exhibited higher levels in the pre-monsoon season. The principle component analysis for ionic source identification was synthesized into three factors with eigen values cut off at greater than unity and explained about 64.8% of the total variance. The extracted factors seemed to be associated to the geogenic, extensive mining and allied transportation sources of the elements. The heavy metal pollution index (HPI) of the mine water calculated for the individual locations varied from 7.1 to 49.5. Most of the locations fall under low to medium classes of HPI except few locations which are under the influence of surface mining and associated transportation.

    Full Text Available Background: Sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. This study was carried out for assessing Co, Ni, and Zn in sediment samples of Mighan Wetland using geo-accumulation index in 2013. Methods:The sediment samples were taken from 11 stations. The samples were subjected to bulk digestion and chemical partitioning and Co, Ni, and Zn concentrations of the sediments were determined by ICP-OES. Geo-accumulation index (I-geo was used to evaluate the magnitude of contaminants in the sediment profile. Results: The results showed that Co, Ni, and Zn concentrations in the sediment samples were 10.0±0.65-60.0±3.79, 21.0±1.71-42.0±2.80, and 64.0±6.97-263.0±26.13 µg g-1, respectively. Moreover, according to the I-geo values, the sediments’ qualities fell into the unpolluted category. Conclusion: Although at present, sediments of Mighan Wetland are not polluted with heavy metals, disposal of urban and industrial wastewaters into the wetland as well as the settlement of Iran Mineral Salt Company and the establishment of Arak Refinery in the vicinity of the wet-land, can discharge different pollutants especially heavy metals to the wetland and cause irreparable damages in the long run.

    The main purpose of this study was to examine the psychometric properties of the Portuguese version of the Behavioral Regulation in Exercise Questionnaire (BREQ-2) and to test the hypothesis that the different types of behavioral regulation can be combined on a single factor to assess autonomous and controlled motivation. Data were collected from 550 members of private fitness centres who ranged in age from 14 to 69 years. The analysis supported an 18-item, 5-factor model after excluding one item (S-B chi2 = 221.7, df = 125, p = .000, S-B chi2/df = 1.77; SRMR = .06; NNFI = .90; CFI = .92; RMSEA = .04, 90% CI = .03-.05). However, the analysis also revealed a lack of internal consistency. The results of a hierarchical model based on 2 second-order factors that reflected controlled motivation (external and introjected regulation) and autonomous motivation (identified and intrinsic regulation) provided an acceptable fit to the data (S-B chi2 = 172.6, df = 74, p = .000, S-B chi2/df = 2.33; SRMR = .07; NNFI = .90; CFI = .92; RMSEA = .05, 90% CI = .04-.06), with reliability coefficients of .75 for controlled motivation and .76 for autonomous motivation. The study findings indicated that when item 17 was excluded, the Portuguese BREQ-2 was an appropriate measure of the controlled and autonomous motivation in exercise.

    Little information is available about the nutrition of people with diabetes from Africa. For the treatment and prevention of diabetes by nutrition, we have assessed the major local foods in a baseline study. The staple foods and meal frequencies of 53 outpatients with type-2 diabetes were assessed in a 24-hour dietary recall based on a questionnaire at a diabetes clinic in northern Tanzania in November and December 1999. In addition, data on weight and height, casual blood glucose, urinary glucose and diabetes therapy were ascertained. 72% of the patients had a body mass index of > or =25 kg/m(2); 64% of patients had casual blood glucose levels of >7.8 mmol/l, 47% had >11.1 mmol/l, and most of them were treated by sulfonylureas or conventional insulin therapy. The test for urinary glucose highly correlated with the blood glucose values, and was positive in 59% of patients. 36% of the patients had milk, amaranth leaves, orange and sunflower oil. The main beverages were water, tea and milk. The baseline data obtained enable more precise dietary assessment and emphasize the need to collect more data on local food consumption in areas where pharmacological diabetes treatment is limited.

    Full Text Available In order to realize economic and social green development, to pave a pathway towards China’s green regional development and develop effective scientific policy to assist in building green cities and countries, it is necessary to put forward a relatively accurate, scientific and concise green assessment method. The research uses the CCR (A. Charnes & W. W. Cooper & E. Rhodes Data Envelopment Analysis (DEA model to obtain the green development frontier surface based on 31 regions’ annual cross-section data from 2008–2012. Furthermore, in order to classify the regions whereby assessment values equal to 1 in the CCR model, we chose the Super-Efficiency DEA model for further sorting. Meanwhile, according to the five-year panel data, the green development efficiency changes of 31 regions can be manifested by the Malmquist index. Finally, the study assesses the reasons for regional differences; while analyzing and discussing the results may allude to a superior green development pathway for China.

    Despite a significant progress in loading and design codes of seismic resistant structures and technology improvements in building structures, the field of civil engineering is still facing critical challenges. An example of those challenges is the assessment of the state of damage that has been imposed to a structure after earthquakes of different intensities. To determine the operability of a structure and its resistance to probable future earthquakes, quick assessment of damages and determining the operability of a structure after an earthquake are crucial. Present methods to calculate damage to structures are time consuming and do not accurately provide the rate of damage. Damage estimation is important task in the fields of structural health monitoring and decision-making. This study examines the relationship between period elongation and the Park-Ang damage index. A dynamic non-linear analysis is employed with IDARC program to calculate the amount of damage and period of the current state. This new method is shown to be a quick and accurate technique for damage assessment. It is easy to calculate the period of an existing structure and changes in the period which reflects changes in the stiffness matrix.

    Land carrying capacity (LCC) explains whether the local land resources are effectively used to support economic activities and/or human population. LCC can be evaluated commonly with two approaches, namely ecological footprint analysis (EFA) and the index system method (ISM). EFA is helpful to investigate the effects of different land categories whereas ISM can be used to evaluate the contributions of social, environmental, and economic factors. Here we compared the two LCC-evaluation approaches with data collected from Xiamen City, a typical region where rapid economic growth and urbanization are found in China. The results show that LCC assessments with EFA and ISM not only complement each other but also are mutually supportive. Both assessments suggest that decreases in arable land and increasingly high energy consumption have major negative effects on LCC and threaten sustainable development for Xiamen City. It is important for the local policy makers, planners and designers to reduce ecological deficits by controlling fossil energy consumption, protecting arable land and forest land from converting into other land types, and slowing down the speed of urbanization, and to promote sustainability by controlling rural-to-urban immigration, increasing hazard-free treatment rate of household garbage, and raising energy consumption per unit industrial added value. Although EFA seems more appropriate for estimating LCC for a resource-output or self-sufficient region and ISM is more suitable for a resource-input region, both approaches should be employed when perform LCC assessment in any places around the world.

    Axitinib, an antiangiogenic multikinase inhibitor (MKI), was evaluated in the compassionate use programme (CUP) in Spain (October 2012-November 2014). 47 patients with advanced radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC, n = 34) or medullary thyroid cancer (MTC, n = 13) with documented disease progression were treated with axitinib 5 mg b.i.d. The primary efficacy endpoint was objective response rate (ORR) by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1. Progression-free survival (PFS) and adverse events (AEs) were secondary objectives. Regulatory authorities validated the CUP, and all patients signed informed consent form. Axitinib was administered as first-line therapy in 17 patients (36.2%), as second-line in 18 patients (38.3%) and as third/fourth-line in 12 patients (25.5%). With a median follow-up of 11.5 months (0-24.3), ORR was 27.7% (DTC: 29.4% and MTC: 23.1%) and median PFS was 8.1 months (95% CI: 4.1-12.2) (DTC: 7.4 months (95% CI: 3.1-11.8) and MTC: 9.4 months (95% CI: 4.8-13.9)). Better outcomes were reported with first-line axitinib, with an ORR of 53% and a median PFS of 13.6 months compared with 16.7% and 10.6 months as second-line treatment. Twelve (25.5%) patients required dose reduction to 3 mg b.i.d. All-grade AEs included asthenia (53.2%), diarrhoea (36.2%), hypertension (31.9%) and mucositis (29.8%); grade 3/4 AEs included anorexia (6.4%), diarrhoea (4.3%) and cardiac toxicity (4.3%). Axitinib had a tolerable safety profile and clinically meaningful activity in refractory and progressive thyroid cancer regardless of histology as first-line therapy. To our knowledge, this is the first time that cross-resistance between MKIs is suggested in thyroid cancer, highlighting the importance of prospective sequential clinical studies. © 2017 European Society of Endocrinology.

  9. A Novel Index Using Ankle Hemodynamic Parameters to Assess the Severity of Peripheral Arterial Disease: A Pilot Study.

    Directory of Open Access Journals (Sweden)

    Jun Tanno

    Full Text Available In peripheral arterial disease (PAD of the lower extremities, the presence of flow-limiting stenoses can be objectively detected by the ankle-brachial index (ABI. However, the severity of ischemic symptoms is not necessarily associated with the ABI value. Atherosclerotic plaque in lower extremity PAD induces ankle arterial stiffness and reduces ankle vascular resistance, which may decrease ankle blood flow and cause ischemic symptoms. We hypothesized that the ankle hemodynamic index (AHI, defined as the ratio of ankle arterial stiffness to ankle vascular resistance, could be used to assess the blood supply deficiency in a diseased lower limb in patients with PAD. The 85 consecutive patients with PAD who were retrospectively analyzed in this study had Rutherford grade 1 to grade 6 ischemia diagnosed as PAD and significant stenotic lesions (>50% diameter stenosis of the lower extremity on contrast angiography. The AHI was calculated as the product of the ankle pulse pressure and the ratio of heart rate to ankle mean arterial pressure (ankle pulse pressure × heart rate/ankle mean arterial pressure. The Rutherford grade was significantly correlated with the AHI (r = 0.50, P < 0.001, but not with the ABI (r = 0.07, P = 0.52. Multiple ordinal regression analysis showed that anemia (odds ratio 0.66, P = 0.002 and AHI (odds ratio 1.04, P = 0.02 were independently associated with Rutherford grade. Our study shows that AHI, a novel parameter based on the ABI measurement, is well correlated with ischemic symptoms, and may be a useful means to assess the arterial blood supply of the lower extremities of patients with PAD.

    The aim of the study was to verify the Mannheim Peritonitis Index (MPI) suitability to determine the probability of death among patients in Polish population operated due to peritonitis and to assess the possibility of using the Index to determine the risk of postoperative complications, relaparotomy and need for postoperative hospitalization in intensive care unit. Retrospective analysis covered 168 patients (M: F = 83: 85, mean age = 48.45 years, SD ± 22.2) treated for peritonitis. The MPI score was calculated for each patient. According to MPI results, patients were divided to the appropriate groups ( 29) and within analyzed. The statistical analysis used Chi-square, Mann Withney U and Kolmogorov-Smirnov test. The best cut-off point for MPI was calculated on the basis of ROC analisys. Mortality in the study group was 13.1%. In groups 29 points according to MPI mortality was 1.75%, 28.13% and 50% respectively, the difference was statistically significant (p = 0.0124). Significant differences were observed in mortality depending on the diagnosis. Based on the ROC curve the cut-off point was identified as 32 with an accuracy of 85.9% and AUC = 81%. There has been a significant correlation between the MPI count and and the occurrence of: cardio-respiratory failure, acidosis, electrolyte imbalance, surgical wound complications, the need for treatment in the intensive care unit after surgery. The MPI is a simple and effective predictor of death among patients operated due to peritonitis. It can also provide assistance in assessing the risk of postoperative complications and the need for treatment in the intensive care unit.

    Full Text Available Rotavirus infection causes a significant proportion of diarrhea in infants and young children worldwide leading to dehydration, hospitalization, and in some cases death. Rotavirus infection represents a significant burden of disease in developing countries, such as those in South Asia.We conducted a meta-analysis to examine how patterns of rotavirus infection relate to temperature and precipitation in South Asia. Monthly rotavirus data were abstracted from 39 published epidemiological studies and related to monthly aggregated ambient temperature and cumulative precipitation for each study location using linear mixed-effects models. We also considered associations with vegetation index, gathered from remote sensing data. Finally, we assessed whether the relationship varied in tropical climates and humid mid-latitude climates.Overall, as well as in tropical and humid mid-latitude climates, low temperature and precipitation levels are significant predictors of an increased rate of rotaviral diarrhea. A 1°C decrease in monthly ambient temperature and a decrease of 10 mm in precipitation are associated with 1.3% and 0.3% increase above the annual level in rotavirus infections, respectively. When assessing lagged relationships, temperature and precipitation in the previous month remained significant predictors and the association with temperature was stronger in the tropical climate. The same association was seen for vegetation index; a seasonal decline of 0.1 units results in a 3.8% increase in rate of rotavirus.In South Asia the highest rate of rotavirus was seen in the colder, drier months. Meteorological characteristics can be used to better focus and target public health prevention programs.
