    Full Text Available With the change of education policy in 1991, more and more technical institutions are being set up in India. Some of these institutions provide quality education, but others are merely concentrating on quantity. These stakeholders are in a state of confusion about decision to select the best institute for their higher educational studies. Although various agencies including print media provide ranking of these institutions every year, but their results are controversial and biased. In this paper, the authors have made an endeavor to find the critical factors for technical institution evaluation from literature survey. A Pareto analysis has also been performed to find the intensity of these critical factors in evaluation. This will not only help the stake holders in taking right decisions but will also help the management of institutions in benchmarking for identifying the most important critical areas to improve the existing system. This will in turn help Indian economy.

  9. Critical review on what factors affected the evolution of the Fukushima accident

    International Nuclear Information System (INIS)

    This paper focuses on why the Fukushima disaster caused such different outcomes at the Fukushima Daiichi nuclear power station (NPS) and the Fukushima Daini NPS, although both NPSs were hit by the largest tsunami in Japanese historical records and are located only 10 km apart. First, the authors' study classifies the progression of the Fukushima accident into four phases: Phase I (between earthquake occurrence and tsunami inundation), Phase II (after tsunami inundation), Phase III (efforts at restoration) and Phase IV (recovery from harsh conditions), in order to clarify the difference in the accident progression in each unit of both NPSs. The course of the accident's evolution at each unit is compared to derive the differences of mechanical and human factors which affected the accident's progression. Second, the differences of both factors are reviewed from resilience engineering perspectives to know what factors are important to improve the safety of nuclear power plants. As the conclusions of this critical review, it can be said that: (1) the system, structures and components of NPS are systematically designed, manufactured and maintained to perform the intended functions for expected events, however they have limitations to cope with unexpected events, and (2) the plant personnel can respond to such situations successfully by changing their approach flexibly in a number of ways.

  10. Critical factors affecting the integration of biomass gasification and syngas fermentation technology

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Gasification-fermentation is a thermochemical-biological platform for the production of fuels and chemicals. Biomass is gasified at high temperatures to make syngas, a gas composed of CO, CO2, H2, N2 and other minor components. Syngas is then fed to anaerobic microorganisms that convert CO, CO2 and H2 to alcohols by fermentation. This platform offers numerous advantages such as flexibility of feedstock and syngas composition and lower operating temperature and pressure compared to other catalytic syngas conversion processes. In comparison to hydrolysis-fermentation, gasification-fermentation has a major advantage of utilizing all organic components of biomass, including lignin, to yield higher fuel production. Furthermore, syngas fermentation microorganisms do not require strict CO:H2:CO2 ratios, hence gas reforming is not required. However, several issues must be addressed for successful deployment of gasification-fermentation, particularly those that involve the integration of gasification and fermentation. Most previous reviews have focused only on either biomass gasification or syngas fermentation. In this review, the critical factors that affect the integration of biomass gasification with syngas fermentation, such as carbon conversion efficiency, effect of trace gaseous species, H2 to CO ratio requirements, and microbial preference of carbon substrate, are thoroughly discussed.

    Full Text Available Sorting allows information or data to be put into a meaningful order. As efficiency is a major concern of computing, data are sorted in order to gain the efficiency in retrieving or searching tasks. The factors affecting the efficiency of shell, Heap, Bubble, Quick and Merge sorting techniques in terms of running time, memory usage and the number of exchanges were investigated. Experiment was conducted for the decision variables generated from algorithms implemented in Java programming and factor analysis by principal components of the obtained experimental data was carried out in order to estimate the contribution of each factor to the success of the sorting algorithms. Further statistical analysis was carried out to generate eigenvalue of the extracted factor and hence, a system of linear equations which was used to estimate the assessment of each factor of the sorting techniques was proposed. The study revealed that the main factor affecting these sorting techniques was time taken to sort. It contributed 97.842%, 97.693%, 89.351%, 98.336% and 90.480% for Bubble sort, Heap sort, Merge sort, Quick sort and Shell sort respectively. The number of swap came second contributing 1.587% for Bubble sort, 2.305% for Heap sort, 10.63% for Merge sort, 1.643% for Quick sort and 9.514% for Shell sort. The memory used was the least of the factors contributing negligible percentage for the five sorting techniques. It contributed 0.571% for Bubble sort, 0.002% for Heap sort, 0.011% for Merge sort, 0.021% for Quick sort and 0.006% for Shell sort.

    2015-01-01

    Next to xylanases, laccases from fungi and alkali-tolerant bacteria are the most important biocatalysts that can be employed for eco-friendly biobleaching of hard and soft wood pulps in the paper industry. Laccases offer a potential alternative to conventional, environmental-polluting chlorine and chlorine-based bleaching and has no reductive effect on the final yield of pulp as compared to hemicellulases (xylanases and mannanases). In the last decade, reports on biobleaching with laccases are based on laboratory observations only. There are several critical challenges before this enzyme can be implemented for pulp bleaching at the industrial scale. This review discusses significant factors like redox potential, laccase mediator system (LMS)-synthetic or natural, pH, temperature, stability of enzyme, unwanted grafting reactions of laccase, and cost-intensive production at large scale which constitute a great hitch for the successful implementation of laccases at industrial level.

    2014-05-01

    Rock slope instability, small-scale rockfalls and associated talus slopes are widespread phenomena in mountain environments. The heterogeneous spatial pattern, sediment properties and volume of talus deposits in alpine valleys reflect a complicated set of various variables governing the spatial and temporal occurrence of slope failure. However, the dynamic and non-linear interplay between environmental settings, the mechanical properties of the rock mass, its discontinuities and different weathering processes promoting rock degradation makes the identification of the dominant destabilizing factors a difficult task. In our project we studied the instability of permafrost-affected rockwalls (Nyenhuis et al., 2005) in the high alpine Turtmann Valley in the Swiss Alps (110 km2). Here, we present a combination of (i) meso-scale spatial analyses and (ii) local-scale geotechnical investigations of critical factors on rockwall instability and (iii) incorporate the results into a theoretical concept with respect to abiotic and biotic weathering processes. (i) To explain the spatial variability of talus deposits stored in 14 WE-oriented hanging valleys, a detailed geomorphological map of 220 talus slopes (Otto et al. 2009) was spatially combined with different key variables of the rockfall source area including topography, climate, lithology and rockwall morphometry. The talus slopes are strongly oriented towards north indicating reduced solar radiation. This aspect-driven trend appears to support the high significance of frost weathering processes as dominant mechanism for rock slope instability, in particular during thawing phases of rockwall permafrost. (ii) To assess the role of mechanical properties of rockwalls at local scales, field surveys of rock discontinuities were performed at selected rockwalls with and without talus slopes based on ISRM standards. Geotechnical investigations reveal discontinuity orientations and spacings that might effectively promote rock

    Full Text Available Introduction To determine the parameters affecting the outcome of ureteroneocystostomy (UNC procedure for vesicoureteral reflux (VUR. Materials and Methods Data of 398 patients who underwent UNC procedure from 2001 to 2012 were analyzed retrospectively. Different UNC techniques were used according to laterality of reflux and ureteral orifice configuration. Effects of several parameters on outcome were examined. Disappearance of reflux on control VCUG or absence of any kind of UTI/symptoms in patients without control VCUG was considered as clinical improvement. Results Mean age at operation was 59.2 ± 39.8 months and follow-up was 25.6 ± 23.3 months. Grade of VUR was 1-2, 3 and 4-5 in 17, 79, 302 patients, respectively. Male to female ratio was 163/235. UNC was performed bilaterally in 235 patients and intravesical approach was used in 373 patients. The frequency of voiding dysfunction, scar on preoperative DMSA, breakthrough infection and previous surgery was 28.4%, 70.7%, 49.3% and 22.4%, respectively. Twelve patients (8.9% with postoperative contralateral reflux were excluded from the analysis. Overall clinical improvement rate for UNC was 92%. Gender, age at diagnosis and operation, laterality and grade of reflux, mode of presentation, breakthrough infections (BTI under antibiotic prophylaxis, presence of voiding dysfunction and renal scar, and operation technique did not affect the surgical outcome. However, the clinical improvement rate was lower in patients with a history of previous endoscopic intervention (83.9% vs. 94%. Postoperative UTI rate was 27.2% and factors affecting the occurrence of postoperative UTI were previous failed endoscopic injection on univariate analysis and gender, preoperative BTI, postoperative VUR state, voiding dysfunction on multivariate analysis. Surgery related complication rate was 2% (8/398. These were all low grade complications (blood transfusion in 1, hematoma under incision in 3 and prolonged

    Habitat destruction has resulted in the extinction of many plant species from the earth, and many more face extinction. Likely, the annual endemic Mediterranean knapweed ( Centaurea tchihatcheffii) growing in the Golbasi district of Ankara, Turkey is facing extinction and needs urgent conservation. Plant tissue culture, a potentially useful technique for ex situ multiplication, was used for the restoration of this ill-fated plant through seed germination, micropropagation from stem nodes, and adventitious shoot regeneration from immature zygotic embryos. The seeds were highly dormant and very difficult to germinate. No results were obtained from the micropropagation of stem nodes. However, immature zygotic embryos showed the highest adventitious shoot regeneration on Murashige and Skoog (MS) medium, containing 1 mg l-1 kinetin and 0.25 mg l-1 NAA. Regenerated shoots were best rooted on MS medium containing 1 mg l-1 IBA and transferred to the greenhouse for flowering and seed set. As such, the present work is the first record of in vitro propagation of critically endangered C. tchihatcheffii, using immature zygotic embryos, and is a step forward towards conservation of this indigenous species.

    1992-01-01

    Within the past year at our transplant center we have had the experience of performing renal allografts in two patients older than 65 years, each of whom had been on hemodialysis more than 10 years. Both resulted in patient mortality within 90 days of transplant (one due to myocardial infarction, the other due to visceral ischemia with infarction). This prompted us to review retrospectively our own data (n = 204) and the national (UNOS) data (n = 10,971) regarding transplant outcome, patient age, and length of time on dialysis prior to renal transplantation. This review revealed that patient mortality after transplant increased with the length of end-stage renal disease (dialysis, regardless of type) independent of age, the greatest mortality occurring within the first 6 months of transplant (and not thereafter); graft survival was similar for all age cohorts analyzed. Our review of the literature reveals a paucity of articles pertaining to post-transplant mortality and length of time on dialysis prior to transplant. Our results indicate the following possible conclusions. (1) The length of time of end-stage renal disease therapy prior to renal transplantation is a significant and independent risk factor for post-transplant mortality. (2) Higher priority should be given to this factor when formulating strategies for allocation of scarce resources. (3) Patients on dialysis for extended periods of time who are elderly may be at particularly high risk. (4) Patients being considered for renal transplant should be informed of their individual risk factors for mortality post-transplant based on length of ESRD therapy. (5) Renal transplantation should be considered as early as possible in patients with ESRD (or imminent ESRD). PMID:14621760

Here we investigated a cost-effective conductive adhesive material consisting of silver-coated copper as micro-fillers using synchrotron-based three-dimensional (3D) X-ray nano-tomography. The key factors affecting the quality and performance of the material were quantitatively studied in 3D on the nanometer scale for the first time. A critical characteristic parameter, defined as a shape-factor, was determined to yield a high-quality silver coating, leading to satisfactory performance. A `stack-and-screen' mechanism was proposed to elaborate such a phenomenon.

  10. Main critical factors affecting the welfare of beef cattle and veal calves raised under intensive rearing systems in Italy: a review

    Flaviana Gottardo

    2010-01-01

    Full Text Available This review describes the principal causes of poor welfare in beef cattle and veal calves raised in intensive husbandry systems in Italy. Nowadays there are no specific regulations in force for beef cattle welfare. However, a document produced in 2001 by the Scientific Committee on Animal Health and Animal Welfare of the European Commission on Health and Consumer Protection identified the main causes of inadequate welfare levels in the different cattle rearing systems in Europe. In Italy and in the Po Valley in particular, the beef cattle farms are mainly finishing units characterised by animals kept at high density in multiple pens and fed high starch diets. Under these rearing conditions the limited space allowance is one of the most important issues impairing animal welfare. Other risk factors for poor welfare related to the housing structures are type of floor, space at the manger, number of water dispensers and lack of specific moving and handling facilities. Microclimatic conditions can be critical especially during the summer season when cattle can experience heat stress. The feeding plan adopted in the Italian beef farms may be another factor negatively affecting the welfare of these animals due to the low content of long fibre roughage which increases the risk of metabolic acidosis. In the veal calf rearing systems there has been a mandatory introduction of the new system of production according to the European Council Directives 91/629/EEC and 97/2/EC. Farms had to adopt group housing and to provide calves with an increasing amount of fibrous feed in addition to the all-liquid diet. Despite this specific legislation, several risk factors for calves’ welfare can still be identified. Some of them are related to the housing system (type of floor, air quality, feed and water supply equipment and lack of loading facilities and some others to the feeding plan (type and amount of roughage, quality of milk replacers.

This study aimed to identify factors affecting the quality of medical services provided by Iranian physicians.Exploratory in-depth individual interviews were conducted with sixty-four physicians working in various medical institutions in Iran.Individual, organizational and environmental factors enhance or inhibit the quality of medical services. Quality of medical services depends on the personal factors of the physician and patient, and factors pertaining to the healthcare setting and the broader environment.Differences in internal and external factors such as availability of resources, patient cooperation and collaboration among providers affect the quality of medical services and patient outcomes. Supportive leadership, proper planning, education and training and effective management of resources and processes improve the quality of medical services. This article contributes to healthcare theory and practice by developing a conceptual framework for understanding factors that influence medical services quality.

    this affects the timing and outcome of a sudden critical transition to a degraded ecosystem state. Based on current results, we hypothesize that including microtopography in the framework of critical transitions in drylands would decrease the amount of pressure that is required to cause a critical shift to a degraded ecosystem state. This is due to a reduction in run-on towards the vegetation patches. So far, we only measured the response of the microtopography to grazing. However, we will continue to study the dynamic interaction between grazing, microtopograpy, vegetation growth, and hydrology. This might be essential to detect early warning signals and to understand the mechanisms responsible for sudden critical transitions in drylands.

    Full Text Available Abstract For optimal individual performance within any equestrian discipline horses must be in peak physical condition and have the correct psychological state. This review discusses the psychological factors that affect the performance of the horse and, in turn, identifies areas within the competition horse industry where current behavioral research and established behavioral modification techniques could be applied to further enhance the performance of animals. In particular, the role of affective processes underpinning temperament, mood and emotional reaction in determining discipline-specific performance is discussed. A comparison is then made between the training and the competition environment and the review completes with a discussion on how behavioral modification techniques and general husbandry can be used advantageously from a performance perspective.

    2016-01-01

    Dietary intake and nutritional status of individuals are important factors affecting mental health and the development of psychiatric disorders. Majority of scientific evidence relating to mental health focuses on depression, cognitive function, and dementia, and limited evidence is available about other psychiatric disorders including schizophrenia. As life span of human being is increasing, the more the prevalence of mental disorders is, the more attention rises. Lists of suggested nutritional components that may be beneficial for mental health are omega-3 fatty acids, phospholipids, cholesterol, niacin, folate, vitamin B6, and vitamin B12. Saturated fat and simple sugar are considered detrimental to cognitive function. Evidence on the effect of cholesterol is conflicting; however, in general, blood cholesterol levels are negatively associated with the risk of depression. Collectively, the aims of this review are to introduce known nutritional factors for mental health, and to discuss recent issues of the nutritional impact on cognitive function and healthy brain aging.

  18. Design factors for safety-critical software

    International Nuclear Information System (INIS)

    This report is the fourth of a series of reports prepared for the Nuclear Regulatory Commission Office Reactor Regulation, and provides the summary and conclusion for this task. It is widely believed in the software engineering community that almost anything can affect the ability of software to reliably its tasks, particularly when safety is at issue. While this statement is true, both in the abstract and in specific instances, it is not particularly helpful. It remains necessary for auditors and other reviewers to assure themselves and the public that safety-critical software has sufficiently low probability of failing in such a way as to cause death or injury to permit it to be used in safety-critical applications. Achieving this assurance is best done by using a well-planned, methodical approach. A possible approach is to concentrate on those attributes of the software and the development process (design factors) that are most influential in achieving dependable software. Seventy-four design factors are identified in this report, divided into nine categories. Seven categories relate to the development process, and one category relates to the products of that process. The remaining category contains negative factors whose presence should be regarded as cause for intense scrutiny of the development process. Seven of the design factors should be considered mandatory for any organization responsible for developing safety-critical software. An additional nine factors are considered essential to safety, but not as important as the first seven. The remaining design factors can provide additional important indications of the quality of the development effort and the software resulting from that effort

  19. Factors Affecting Aerosol Radiative Forcing

    Wang, Jingxu; Lin, Jintai; Ni, Ruijing

    2016-04-01

    Rapid industrial and economic growth has meant a large amount of aerosols in the atmosphere with strong radiative forcing (RF) upon the climate system. Over parts of the globe, the negative forcing of aerosols has overcompensated for the positive forcing of greenhouse gases. Aerosol RF is determined by emissions and various chemical-transport-radiative processes in the atmosphere, a multi-factor problem whose individual contributors have not been well quantified. In this study, we analyze the major factors affecting RF of secondary inorganic aerosols (SIOAs, including sulfate, nitrate and ammonium), primary organic aerosol (POA), and black carbon (BC). We analyze the RF of aerosols produced by 11 major regions across the globe, including but not limited to East Asia, Southeast Asia, South Asia, North America, and Western Europe. Factors analyzed include population size, per capita gross domestic production (GDP), emission intensity (i.e., emissions per unit GDP), chemical efficiency (i.e., mass per unit emissions) and radiative efficiency (i.e., RF per unit mass). We find that among the 11 regions, East Asia produces the largest emissions and aerosol RF, due to relatively high emission intensity and a tremendous population size. South Asia produce the second largest RF of SIOA and BC and the highest RF of POA, in part due to its highest chemical efficiency among all regions. Although Southeast Asia also has large emissions, its aerosol RF is alleviated by its lowest chemical efficiency. The chemical efficiency and radiative efficiency of BC produced by the Middle East-North Africa are the highest across the regions, whereas its RF is lowered by a small per capita GDP. Both North America and Western Europe have low emission intensity, compensating for the effects on RF of large population sizes and per capita GDP. There has been a momentum to transfer industries to Southeast Asia and South Asia, and such transition is expected to continue in the coming years. The

  5. Column: Factors Affecting Data Decay

    Directory of Open Access Journals (Sweden)

    Kevin Fairbanks

    2012-06-01

    Full Text Available In nuclear physics, the phrase decay rate is used to denote the rate that atoms and other particles spontaneously decompose. Uranium-235 famously decays into a variety of daughter isotopes including Thorium and Neptunium, which themselves decay to others. Decay rates are widely observed and wildly different depending on many factors, both internal and external. U-235 has a half-life of 703,800,000 years, for example, while free neutrons have a half-life of 611 seconds and neutrons in an atomic nucleus are stable.We posit that data in computer systems also experiences some kind of statistical decay process and thus also has a discernible decay rate. Like atomic decay, data decay fluctuates wildly. But unlike atomic decay, data decay rates are the result of so many different interplaying processes that we currently do not understand them well enough to come up with quantifiable numbers. Nevertheless, we believe that it is useful to discuss some of the factors that impact the data decay rate, for these factors frequently determine whether useful data about a subject can be recovered by forensic investigation.(see PDF for full column

    Full Text Available Significant advances have been made in our knowledge of forage seed physiology, technology, and stand establishment practices; however, stand establishment continues to be one of the most common production problems affecting forage crops in the USA. There is a need for research on stand establishment of forage crops under abiotic and biotic stress. Although the forage seed industry produces and markets seed of high quality, new methods of assessing seed vigor are needed and their use should be expanded in the industry to enable matching seed lot performance to specific environmental conditions where performance can be maximized. Seed treatment and seed coating are used in the forage seed industry, and studies have shown they are of benefit in some environments. There is an increase in no-tillage seeding of forage crops, but improvements in the no-tillage planting equipment are needed to make them better suited to small seeds. Other recent developments in seeding techniques include broadcasting seed with dry granular and fluid fertilizers, which improves the efficiency of the seeding operation.

  7. Factors Affecting Hurricane Evacuation Intentions.

    Lazo, Jeffrey K; Bostrom, Ann; Morss, Rebecca E; Demuth, Julie L; Lazrus, Heather

    2015-10-01

    Protective actions for hurricane threats are a function of the environmental and information context; individual and household characteristics, including cultural worldviews, past hurricane experiences, and risk perceptions; and motivations and barriers to actions. Using survey data from the Miami-Dade and Houston-Galveston areas, we regress individuals' stated evacuation intentions on these factors in two information conditions: (1) seeing a forecast that a hurricane will hit one's area, and (2) receiving an evacuation order. In both information conditions having an evacuation plan, wanting to keep one's family safe, and viewing one's home as vulnerable to wind damage predict increased evacuation intentions. Some predictors of evacuation intentions differ between locations; for example, Florida respondents with more egalitarian worldviews are more likely to evacuate under both information conditions, and Florida respondents with more individualist worldviews are less likely to evacuate under an evacuation order, but worldview was not significantly associated with evacuation intention for Texas respondents. Differences by information condition also emerge, including: (1) evacuation intentions decrease with age in the evacuation order condition but increase with age in the saw forecast condition, and (2) evacuation intention in the evacuation order condition increases among those who rely on public sources of information on hurricane threats, whereas in the saw forecast condition evacuation intention increases among those who rely on personal sources. Results reinforce the value of focusing hurricane information efforts on evacuation plans and residential vulnerability and suggest avenues for future research on how hurricane contexts shape decision making.

    Cahoon, D.R.

    2007-01-01

    Opening paragraph: Tidal and nontidal wetlands in the Chesapeake Bay watershed provide vital hydrologic, water-quality, and ecological functions. Situated at the interface of land and water, these valuable habitats are vulnerable to alteration and loss by human activities including direct conversion to non-wetland habitat by dredge-and-fill activities from land development, and to the effects of excessive nutrients, altered hydrology and runoff, contaminants, prescribed fire management, and invasive species. Processes such as sea-level rise and climate change also impact wetlands. Although local, State, and Federal regulations provide for protection of wetland resources, the conversion and loss of wetland habitats continue in the Bay watershed. Given the critical values of wetlands, the Chesapeake 2000 Agreement has a goal to achieve a net gain in wetlands by restoring 25,000 acres of tidal and nontidal wetlands by 2010. The USGS has synthesized findings on three topics: (1) sea-level rise and wetland loss, (2) wetland restoration, and (3) factors affecting wetland diversity.

    Full Text Available In an era of spiraling health care costs and limited resources, policy makers and health care payers are concerned about the cost effectiveness of antibiotics. The aim of this study is to draw on published economic evaluations with a view to identify and illustrate the factors affecting the cost effectiveness of antibiotic treatment of bacterial infections. The findings indicate that the cost effectiveness of antibiotics is influenced by factors relating to the characteristics and the use of antibiotics (i.e., diagnosis, comparative costs and comparative effectiveness, resistance, patient compliance with treatment, and treatment failure and by external factors (i.e., funding source, clinical pharmacy interventions, and guideline implementation interventions. Physicians need to take into account these factors when prescribing an antibiotic and assess whether a specific antibiotic treatment adds sufficient value to justify its costs.

    Full Text Available Industrial companies have been implementing Computer Aided Engineering tools for many years with varying degrees of success. In the early implementations considerable emphasis was placed upon the organisational structure necessary to receive and optimise system output. However, it is becoming increasingly clear that any successful CAE implementation has to satisfy three inter-related factors of technology, organisation and human issues. This paper presents the results of an investigation into human factors affecting successful CAD implementation, undertaken through selected case studies and a more general survey of UK industry.

    Full Text Available Hunger, extreme desire to eat a certain food, taste, price, and convenience are among the main There are various factors that affect food preferences. Hunger, extreme desire to eat a certain food, taste, price, and convenience are among the main factors affecting food preferences. Additionally, general nutritional habits, family, friends, commercials, and availability of the food are also important for food preferences. Also, past experiences with foods are related to preferring or rejecting some foods. Socializing more with increasing age causes change in the food preferences of adolescents. Unhealthy nutrition habits form as a result of the adolescents consuming fast foods, spending time with their friends outside the house, and consuming more ready-made foods. Current developments in the food industry result in an increase in variety and consumption of snacks such as cookies, chocolate, chips, and crackers in adolescents. Considering all these, in this rewiev article, environmental and personal factors affecting food preferences have been investigated. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2013; 11: 121-7

    Full Text Available This study aimed to examine key factors affecting rural female facilitators’ role in participatory rural developmentin Tehran Province. Since the researchers intended to have abetter insight into the facilitators’ role and employ inquiry as alearning forum for bringing about changes for all participants,they preferred to use a case study based upon an appreciativeinquiry method. The study divided the factors affecting thefacilitators’ role into two main categories: driving factors andpreventing factors. The former are: two-way communication,election of rural eligible facilitators, participation, sense ofresponsibility, and the latter are: cultural and tribal fanaticism,lack of permanent female extension workers and frequentmanagement changes. Appreciative inquiry as a positive modeof action research could facilitate the process of education andcommunication for all stakeholders. We suggested that thereshould be a shift from the extension as a knowledge transfer tofacilitation as people’s own knowledge creation. This studyshowed that appreciative inquiry could facilitate the process ofchange and gender-awareness. This research method couldalso facilitate mutual communication between the rural facilitatorsand extension workers.

    In biological fluids, proteins bind to the surface of nanoparticles to form a coating known as the protein corona, which can critically affect the interaction of the nanoparticles with living systems. As physiological systems are highly dynamic, it is important to obtain a time-resolved knowledge of protein-corona formation, development and biological relevancy. Here we show that label-free snapshot proteomics can be used to obtain quantitative time-resolved profiles of human plasma coronas formed on silica and polystyrene nanoparticles of various size and surface functionalization. Complex time- and nanoparticle-specific coronas, which comprise almost 300 different proteins, were found to form rapidly (<0.5 minutes) and, over time, to change significantly in terms of the amount of bound protein, but not in composition. Rapid corona formation is found to affect haemolysis, thrombocyte activation, nanoparticle uptake and endothelial cell death at an early exposure time.

The following variables were evaluated: gross feed efficiency, adjusted feed efficiency, dry matter intake, milk-yield, 3.5% fat-corrected milk yield, dry matter digestibility, dietary neutral detergent fiber content, different roughage-to-concentrate ratios and body weight. The statistical analyses involved the application of descriptive and dispersion measures besides Pearson's correlation coefficient and linear regression analysis. The analyzed variables were highly correlated with feed efficiency. The feed efficiency of lactating goats was affected by the milk fat correction, dry matter digestibility, dietary fiber content, proportion of roughage in the diet and body weight. Among these factors, standardization of the milk fat appeared to be the most efficient in correcting the feed efficiency in lactating goats. Correction of some of these factors implies greater precision in the measurement of feed efficiency.

  6. Critical factors in environmental impact assessment

    International Nuclear Information System (INIS)

    Environmental impact assessment (EIA) has shown that it is of proven benefit to the overall planning and environmental management of resource development projects, but certain elements within the application and practice of EIA remain problematic for proponents and regulatory decision makers alike. The use of the word 'critical' in the title of this paper suggests that if the components identified are not considered or implemented properly through the process of EIA, the product will be of less value to both the proponent and decision maker. In the context of EIA, the regulatory, financial, legal and social benefits that accrue make the need for good EIA practice even more imperative. A discussion is included that highlights a number of issues that need to be addressed to improve the effectiveness of EIA, a tool necessary to attaining provincial and federal regulatory approvals. To a large extent, the discussion reflects items of contemporary public concern, and those emerging issues of the scientific and regulatory community. At the same time, it needs to be realized that not all the identified items are necessarily new to the practice of impact assessment, but are nonetheless important to professional environmental impact assessment and decision making. Insight is also provided into the direction of decision making of the Energy and Utilities Board as it will affect the regulatory review and administration of resource development projects in the province of Alberta. 16 refs

    Purpose: To investigate the correlation of various corneal hysteresis (CH) factors in Chinese adults. Methods: From January 2009 to November 2011, the healthy right eyes of a total of 292 adults were recruited into the study. Goldmann-correlated intraocular pressure (IOPG) and CH were measured using an ocular response analyzer (ORA). Central corneal thickness was measured using the ORA’s in-tegrated handheld ultrasonic pachymeter. The IOLMaster was used to obtain the ocular biometric measurements including axial length, anterior chamber depth, and keratometric values. The Pearson correlation coefficient was used to test correla-tions between CH and quantitative factors. The chi-square test was used to detect differences in categorical values. Results: Longer axial length (P=0.0001), lower IOPG (P=0.03), older age(P=0.003),and thinner central corneal thick-ness (P=0.0001) were significantly associated with lower CH. The anterior chamber depth (P=0.34), gender (P=0.23), and corneal curvature (P=0.18) had no relationship to CH. Conclusion:Various factors including axial length, intraocular pressure, age, and central corneal thickness can affect measure-ment of corneal biomechanical properties in Chinese adults. But the anterior chamber depth, gender, and corneal curvature were irrelevant to CH.

    The myxosporean parasite Kudoa septempunctata has been isolated from cultured olive flounder (Paralichthys olivaceus) and was recently identified as a cause of food poisoning in humans. Since the sporoplasm plays an important role in causing diarrhea by invading intestinal cells, the specific factors affecting the release of sporoplasm from spores should be determined. Thus, we investigated the effect of digestive and serum enzymes, fetal bovine serum (FBS), temperature, and the role of glucose in cell culture media on the release of sporoplasm. Sporoplasm release was observed in the groups treated with FBS and media containing glucose. In addition, 1,10-phenanthroline inhibited the release of sporoplasm in the FBS medium. These results indicate that K. septempunctata uses glucose for releasing its sporoplasm and that zinc or metalloprotease is related to the release mechanism. The present study provides important information for the development of agents to prevent sporoplasm release and the consequent food poisoning caused by K. septempunctata. PMID:25563617

  9. Factors affecting passive monitoring of radon

    International Nuclear Information System (INIS)

    In recent years, increasing cancer has been expressed as a possible health hazards associated with long-term exposures to a large population at a low level of radon in the environment. Because radon is ubiquitous nuclide, nation-wide monitoring is necessary to determine lung cancer risk. For such purpose, passive sampling methods with track etch detector or charcoal adsorption collector may have the advantage in lower cost and convenience. The charcoal adsorption collector is considered in this study. Various factors may significantly affect the charcoal adsorption mechanism on its practical application. Moisture effects are discussed here as having major impact on radon collection by charcoal. Set of equations are presented in this report to describe adsorption of radon including moisture effects.

    Full Text Available Outdoor leisure activities are important for public health as well as family cohesiveness, yet environmental factors may easily affect someone’s ability to participate in such activities. We explored this with a focus on the social web-based treasure hunt game called Geocaching. We collected data on all US and Canadian geocaches from OpenCaching.com and conducted an online survey with twenty geocachers as a follow-up to our data analysis. Data analysis showed that geocaches were more often found in areas that were wealthier, better educated, younger, and more urban, and had higher population density and better weather. Survey results showed similar trends: Most people actively thought about where they would cache and tried to minimize risks, despite cache hiders thinking less about these concerns. These results further emphasize the importance of environmental factors when it comes to participation in outdoor activities and leads to Human–Computer Interaction design implications for location-based online social activities.

  12. Factors affecting seismic response of submarine slopes

    2006-01-01

    Full Text Available The response of submerged slopes on the continental shelf to seismic or storm loading has become an important element in the risk assessment for offshore structures and 'local' tsunami hazards worldwide. The geological profile of these slopes typically includes normally consolidated to lightly overconsolidated soft cohesive soils with layer thickness ranging from a few meters to hundreds of meters. The factor of safety obtained from pseudo-static analyses is not always a useful measure for evaluating the slope response, since values less than one do not necessarily imply slope failure with large movements of the soil mass. This paper addresses the relative importance of different factors affecting the response of submerged slopes during seismic loading. The analyses use a dynamic finite element code which includes a constitutive law describing the anisotropic stress-strain-strength behavior of normally consolidated to lightly overconsolidated clays. The model also incorporates anisotropic hardening to describe the effect of different shear strain and stress histories as well as bounding surface principles to provide realistic descriptions of the accumulation of the plastic strains and excess pore pressure during successive loading cycles. The paper presents results from parametric site response analyses on slope geometry and layering, soil material parameters, and input ground motion characteristics. The predicted maximum shear strains, permanent deformations, displacement time histories and maximum excess pore pressure development provide insight of slope performance during a seismic event.

    Full Text Available Absorption of drugs from the gastrointestinal tract is a complex process the variability of which is influenced by many physicochemical and physiologic factors. The two most important physicochemical factors that affect both the extent and the rate of absorption are lipophilicity and solubility. The rate and extent of absorption are governed by the solubility, permeability and stability of the drug, with solubility being a pH-dependent parameter for weak acids and bases. The gastrointestinal tract can be viewed as discrete sections with a variety of differential local pH environments ranging from the acidic stomach to the more basic small intestine. The multiple peaking, double peaking or secondary peaking phenomena can occur in the disposition of a variety of xenobiotics during drug development (the pre-clinical phase and in subsequent clinical studies and use. The physicochemical and physiological mechanisms underlying the occurrence of this phenomenon are often multi factorial and include but are not limited to solubility-limited absorption, modified-release formulations, complexation, enterohepatic recirculation, gastric emptying and the intestinal transit time, site-specific absorption, gastric secretion-enteral reabsorption. Double peak absorption has been described with several orally administered drugs such as cimetidine furosemide, piroxicam, ranitidine, talinolol, alprazolam and phenazopyridine.

    Full Text Available This study was undertaken to identify the factors affecting sugarcane production in Pakistan. Data were collected from 387 sugarcane growers from Sindh, Punjab and NWFP province. Data were collected during the period 2007-08. The study reveals that the costs of inputs of sugarcane i.e. urea, DAP, FYM, land preparation, seed and its application, weeding and cost of irrigation were the important factors which influenced on the returns of sugarcane growers. The effectiveness was examined by using the Cobb-Douglas production function; MVP and allocative efficiency were calculated. The coefficient of multiple determinations R2 was 0.9249, which indicated that 92% variation in the cost of inputs was explained by all explanatory variables and the adjusted R2 was 92%. The F-value was 666.94 and was highly significant at 5% level of significance, indicating that the regression model was well fitted. The high prices of inputs, low price of output, delay in payments and lack of scientific knowledge were the major problems in sugarcane production. In order to enhance the productivity of sugarcane in the country, government should solve the identified problems to increase the income of sugarcane growers.

    Full Text Available In response to a shift toward specialization and mechanization during the 20th century, there has been momentum on the part of a vocal contingent of consumers, producers, researchers, and policy makers who call for a transition toward a new model of agriculture. This model employs fewer synthetic inputs, incorporates practices which enhance biodiversity and environmental services at local, regional, and global scales, and takes into account the social implications of production practices, market dynamics, and product mixes. Within this vision, diversified farming systems (DFS have emerged as a model that incorporates functional biodiversity at multiple temporal and spatial scales to maintain ecosystem services critical to agricultural production. Our aim is to provide an economists' perspective on the factors which make diversified farming systems (DFS economically attractive, or not-so-attractive, to farmers, and to discuss the potential for and roadblocks to widespread adoption. We focus on how a range of existing and emerging factors drive profitability and adoption of DFS. We believe that, in order for DFS to thrive, a number of structural changes are needed. These include: 1 public and private investment in the development of low-cost, practical technologies that reduce the costs of production in DFS, 2 support for and coordination of evolving markets for ecosystem services and products from DFS and 3 the elimination of subsidies and crop insurance programs that perpetuate the unsustainable production of staple crops. We suggest that subsidies and funding be directed, instead, toward points 1 and 2, as well as toward incentives for consumption of nutritious food.

    Full Text Available This paper explored the factors that affect career progress of students in the MBA program of the University of the Philippines.To understand career progression, four measures of career progress were used in this study, namely: number of promotions, number of years in between promotions, total cash compensation, and number of administrative levels from the company president. On the other hand, the factors used to explain career progess included human capital, organizational, interpersonal and demographic variables.The results showed that the different measures of career progress had distinct determinants implying different dynamics. It appeared that measures of career progress that are sensitive to the value employers attach to the individual (Whitely, Dougherty, & Dreher, 1991 such as total compensation, total number of promotion and years per promotion were related with human capital factors such as work experience and number of companies worked for. On the other hand, measures that relate to centrality if the position, in which market forces have less impact, were associated with organizational variables such as organization size and the demographic variable gender.While gender did not explain variation in total compensation, number of promotions and number of uears between promotions, these null results are important for two reasons. First, it implies that the female MBA students were at par with their male counterparts as fas as these measures of career progress are concerned. Second, it challenges the generalizability of the finding of gender segregation at the organizational level-where men receive significantly higher wages that women-which is a common finding among studies done in the United States. The results using the MBA students as sample show that income and promotion parity may indeed be achievable and this brings hope to women in general.However, the statistical significance of gender in explaining career progress as centrality

It was raised with the purpose of analyzing the structure of the relationship between critical quality factors and results-social impact, how they operate and the level of their influence on obtaining these results within the company. Starting from a deep theoretical revision we propose a theoretical model together with the hypotheses to be tested, and we proceed to validation using the technique of Structural Equation Models. The results obtained show that companies wishing to improve their social impact should take into account that leadership is the most important factor to achieve it. Leadership indirectly affects the social impact through its influence on alliances and resources, quality policy/planning, personnel management and learning.

    This paper presents the results from a study conducted on the effect of differing factors on a customer's attitude towards using Internet shopping in Japan. The research model used was an extended version of the consumers' acceptance of virtual stores model with the addition of a new factor, need specificity, and a grouping of critical success factors based on their customer-centric and website-centric viewpoints sources. It examines how differences in the individual characteristics of customers affect the actual use of Internet shopping. According to an online questionnaire filled out by 1,215 online customers used to conduct a multiple regression analysis and a structural equation modeling analysis, the participant's gender, education level, innovativeness, net-orientation, and need specificity, which are the factors for the customer-centric viewpoints, have a positive impact on the actual use of Internet shopping. The implication also shows that Japanese online customers do not worry about the quality of service of Internet shopping, a factor in the website-centric viewpoint, as significantly as offline customers do.

    Peter, Graciana; Nkambule, Sizwe E.

    The Millennium Development Goal (MDG) target to reduce the proportion of people without sustainable access to safe drinking water by the year 2015 has been met as of 2010, but huge disparities exist. Some regions, particularly Sub-Saharan Africa are lagging behind it is also in this region where up to 30% of the rural schemes are not functional at any given time. There is need for more studies on factors affecting sustainability and necessary measures which when implemented will improve the sustainability of rural water schemes. The main objective of this study was to assess the main factors affecting the sustainability of rural water schemes in Swaziland using a Multi-Criteria Analysis Approach. The main factors considered were: financial, social, technical, environmental and institutional. The study was done in Lubombo region. Fifteen functional water schemes in 11 communities were studied. Data was collected using questionnaires, checklist and focused group discussion guide. A total of 174 heads of households were interviewed. Statistical Package for Social Sciences (SPSS) was used to analyse the data and to calculate sustainability scores for water schemes. SPSS was also used to classify sustainability scores according to sustainability categories: sustainable, partially sustainable and non-sustainable. The averages of the ratings for the different sub-factors studied and the results on the sustainability scores for the sustainable, partially sustainable and non-sustainable schemes were then computed and compared to establish the main factors influencing sustainability of the water schemes. The results indicated technical and social factors as most critical while financial and institutional, although important, played a lesser role. Factors which contributed to the sustainability of water schemes were: functionality; design flow; water fetching time; ability to meet additional demand; use by population; equity; participation in decision making on operation and

    The consolidation of neoliberal capitalism over the past decade has been intense, as has the articulation of critical and creative responses to it. One of the most remarkable is the turn towards forms of political resistance that seek liberation from the logics of state and capital while – or through – simultaneously creating alternative, radically democratic modes of existence. Many of these draw on anarchistic and autonomist traditions of critical theory which assert the possibility of pref...

    Full Text Available Professional development (PD has attracted a great deal of attention in recent years. Despite research findings, the development of many PD programmes often rests on faulty assumptions of such research or even no research at all. The purpose of this article is threefold: to explain why some PD programmes have been unsuccessful; to outline key factors that may influence the effective implementation of PD and to explain the importance of contextual factors like environment, internal conditions and individual considerations as the major sources of momentum for PD in schools. Specific categories that are high-lighted include the following: learning styles of educators, educator commitment, transformational leadership, out-of-school conditions, in-school conditions and requirements of PD programmes. The design of PD requires a new way of thinking and interacting and, most importantly, should be a step towards improved learner performance.

    Full Text Available Cost is the main driving factor for all projects. When it is done correctly, it helps in the successful completion of the project. In this research we have discussed various factors that affect the estimation procedure. These include team structure, team culture, managerial style, project type (Core application or integrated application, client’s working environment. Accurate estimation is far difficult in developing countries where most of the organizations follow local standards. These inaccurate estimations lead to late delivery, less profit or in worst case complete failure. Software requirement gathering, development, maintenance, quality assurance and cost of poor quality are major groups responsible for overall cost in software production process. The exact proportion among them varies significantly in consecutive software releases, which is caused by many factors. The ever increasing need for the reliability of the software systems, especially mission critical applications in the public safety domain, raises the bar for the accuracy of prediction and estimation techniques. The accuracy of estimations in many areas brings about more concerns regarding techniques already used in the software industry. Widely deployed techniques, such as Wideband Delphi method, stress the engineering and technical aspects of the process of how estimates are prepared.

    2016-07-11

    Purpose - Without use the expected benefits from healthcare management systems (HMS) cannot be derived. Thus, while use alone may not guarantee success, one can safely assume that the more use the better. HMS has been instrumental in facilitating care providers' work. However, many hospitals have encountered usage problems and some user-related factors have been recognized in the literature as potentially important to make HMS more successful. The purpose of this paper is to test the importance of the factors proposed in the literature as important determinants of HMS usage measured by the number of hours used and the frequency of use. Design/methodology/approach - Several user-related variables such as user participation, user expertise, and user training previously studied separately by different authors are brought together into an integrated model to be tested empirically. Data from 213 nurses using their hospital HMS have been used to test proposed relationships between the independent variables and HMS usage results. Findings - The results confirm the importance of these factors and provide the basis for managerial recommendations. Hospital managers can use the resources validated by this study to improve their own operations and improve the likelihood of success implementing HMS. Future research projects may identify other possible factors important for HMS implementation success to improve the model proposed here. Originality/value - HMS is a very widely used and an important system for hospitals, but has been neglected in research. This is one of the first rigorous studies of HMS, and the results provide new practical insights for hospital administrators. PMID:27298061

  7. Do landscape factors affect brownfield carabid assemblages?

    International Nuclear Information System (INIS)

    The carabid fauna of 28 derelict sites in the West Midlands (England) were sampled over the course of one growing season (April-October, 1999). The study aimed to investigate the relationship between carabid assemblages and five measures of landscape structure pertinent to derelict habitat. At each site measurements of landscape features pertinent to derelict habitat were made: (i) the proximity of habitat corridors; (ii) the density of surrounding derelict land; (iii) the distance between the site and the rural fringe; and (iv) the size of the site. Concurrent surveys of the soil characteristics, vegetation type, and land use history were conducted. The data were analysed using a combination of ordination (DCA, RDA), variance partitioning (using pRDA) and binary linear regression. The results suggest that:1.There is very little evidence that the carabid assemblages of derelict sites were affected by landscape structure, with assemblages instead being principally related to within-site habitat variables, such as site age (since last disturbance), substrate type and vegetation community. 2.No evidence was found to support the hypothesis that sites away from railway corridors are more impoverished in their carabid fauna than sites on corridors. 3.There are some suggestions from this study that rarer and non-flying specialist species may be affected by isolation, taking longer to reach sites. We infer from this that older sites with retarded succession, and sites in higher densities of surrounding derelict land may eventually become more species rich and that these sites may be important for maintaining populations of rarer and flightless species. 4.Conservation efforts to maintain populations of these species should focus principally on habitat quality issues, such as maintaining early successional habitats that have a diversity of seed producing annuals and perennial plants and enhancing substrate variability rather than landscape issues

  9. Circulation factors affecting precipitation over Bulgaria

    Nojarov, Peter

    2015-09-01

    The objective of this paper is to determine the influence of circulation factors on precipitation in Bulgaria. The study succeeds investigation on the influence of circulation factors on air temperatures in Bulgaria, as the focus here is directed toward precipitation amounts. Circulation factors are represented through two circulation indices, showing west-east or south-north transport of air masses over Bulgaria and four teleconnection indices (patterns)—North Atlantic Oscillation, East Atlantic, East Atlantic/Western Russia, and Scandinavian. Omega values at 700-hPa level show vertical motions in the atmosphere. Annual precipitation trends are mixed and not statistically significant. A significant decrease of precipitation in Bulgaria is observed in November due to the strengthening of the eastward transport of air masses (strengthening of EA teleconnection pattern) and anticyclonal weather (increase of descending motions in the atmosphere). There is also a precipitation decrease in May and June due to the growing influence of the Azores High. An increase of precipitation happens in September. All this leads to a redistribution of annual precipitation course, but annual precipitation amounts remain the same. However, this redistribution has a negative impact on agriculture and winter ski tourism. Zonal circulation has a larger influence on precipitation in Bulgaria compared to meridional. Eastward transport throughout the year leads to lower than the normal precipitation, and vice versa. With regard to the four teleconnection patterns, winter precipitation in Bulgaria is determined mainly by EA/WR teleconnection pattern, spring and autumn by EA teleconnection pattern, and summer by SCAND teleconnection pattern.

    2005-01-01

    Critical success factors (CSF) for electronic commerce (EC) are important for enterprises.This research discusses both assessment indicators and impact factors for EC success to help Chinese enterprises to achieve successful EC implementations. On the basis of literature review and experts survey, the research suggests some assessment indicators and impact factors for EC success. A hypothesis is proposed that leadership, strategy, management, organization, technology, customers,and suppliers factors would affect EC success. Furthermore, the research conducts an empirical study on the Chinese Electronic Information Industry to verify the hypothesis. Using factor analysis and regression analysis, the research finds out several critical factors--leadership, strategy, and organization--and critical sub-factors, such as leadership belief and organization management. These findings indicate the usefulness of this research model, especially for Chinese enterprises.

    Full Text Available The aim of this paper is to present critical factors that constitute a successful implementation of the Advanced Manufacturing Technologies (AMT in Small Medium Enterprise (SME. Many large companies have applied AMT and the applications have shown significant results in this global market era. Conveniently, these phenomenons are also engaged to Small Medium Enterprises (SME that of high demands on performing high quality product, fast delivery, reliable and more flexible. The implementation of AMT follow several processes namely pre installation, installation, improvement and mature. In order to guarantee the succesfull of running these processes, one should consider the Critical Success Factors (CSF. We conducted a survey to 125 SMEs that have implemented AMT, and found that the CSF for each process are moderately different. Good leadership is the main critical success factor for preparing and installation of the AMT. Once the AMT started or installed and arrived at growth stage, the financial availability factor turns into a critical success factor in the AMT implementation. In, mature stage, the support and commitment of top management becomes an important factor for gaining successful implementation. By means of factor analysis, we could point out that strategic factors are the main factors in pre-installation and installation stage. Finally, in the growth stage and mature stage, both tactical and strategic factors are the important factors in the successful of AMT implementation

  12. Factors affecting the acceptance of nuclear energy

    International Nuclear Information System (INIS)

    Nuclear energy all over Europe faces political resistance. Politicians refer to the results of public opinion polls that show considerable resistance towards the use of nuclear power. However, responses to general questions on nuclear energy are 'soft', depending on the design of the questions, and, above all, on the situation at hand. Provided there is a need for nuclear energy, the ambivalent majority accepts this source of power. However, there is no doubt that a hard core of opponents to the use of nuclear energy under all circumstances is slowly increasing. While leadership groups prefer to explain their lack of, or only lukewarm, support for nuclear energy as being the result of public resistance, this resistance is to a large extent the result of the behaviour of key groups in opinion formation. The public has little competence in such technical issues, and also little patience in evaluating information remote from its daily concerns. The most important message the public in various countries believes it is getting from leadership groups is the impression that nuclear energy is controversial among experts. This impression is a consequence of the preferred source of information, namely television and newspapers. Surveys of journalists, politicians, scientists in general and those specializing in nuclear issues demonstrate that the farther one of the groups important in the formation of public opinion is, the more critical is its stance with regard to nuclear power. Among specialists, issues surrounding the use of nuclear power are only marginally controversial. The communications elite and cultural intelligentsia are sending the wrong messages to the general public. Thus, the first priority in rectifying this erroneous impression is to change the perceptions and attitudes of key groups involved in the formation of public opinion. 12 refs, 2 figs, 7 tabs

This software addresses customer life cycle management. This system manages company interactions with current and future customers. It involves technology to organize, automate and synchronize business processes. CRM application is an essential tool for a company to grow and help to increase the satisfaction of customers. There are many benefits of CRM; those make the market environment customer centric. In this paper, we reviewed previous studies and identify those benefits which affect customers and company both. But CRM has many problems also because of them CRM gets failure. Its failure rate is more than its success rate. We also elaborated its failure factors and along with them its critical success factors which help in making CRM a successful project for a company, however implementation of CRM is a complex task.

  14. Factors affecting radiolytic effects in food

    International Nuclear Information System (INIS)

    On basis of radiation chemical considerations supported by model system studies, several general predictions can be made regarding the influence of specific parameters on the chemical effects in irradiated foods. Among the parameters considered are: food composition, physical state of components, irradiation temperature, dose-rate, and total dose. Composition determines the type and extent of reactions initiated by both direct and indirect radiolytic interaction. The multiphasic character of foods influences cross reactions between components. State of hydration introduces both physical and chemical aspects into these considerations. Irradiating systems in which the water is frozen changes substantially the chemical effects because the diffusion of reactive entities is impeded. Temperature, especially in frozen systems, has a specific effect on the type and extent of reactions that could occur. Dose and dose-rate, insofar as they affect the pathways for reaction of intermediate species with the original or new components, also determine the type and amount of final radiolysis products. Illustrations of many of these features of the chemistry have been drawn from experiments on model systems of proteins, frozen aqueous solutions, and compounds derived from lipids, as well as from irradiated meats and poultry. These considerations and related experimental results explain the validity of using chemical data to obtain clearances and to extend clearances from approved food to other foods or to other irradiation conditions.

    1976-06-01

    Certain habitat and social factors were investigated for their effect on home range size of mallard (Anas platyhynchos) pairs breeding in a forested region of north-central Minnesota during the spring of 1971--72. Data from 31 radio-marked hens and drakes were used, but primary emphasis was placed on 8 pairs (5 with both members of the pair marked). Pairs were radio-tracked on river marsh areas, river channels, and large sand lakes to provide comparative data for evaluating home range size differences. Home ranges varied from an average of 53 ha for pairs using primarily river habitat to 871 ha for pairs using only large sand lakes. River and lake shorelines varied considerably in species and density of vegetation. Interaction between pairs as well as density of flocked males appeared to be influenced by these habitat differences with resultant effects on home range sizes.

    The synthesis mechanism of the high silica zeolite types other than MFI is rarely studied in the open literature. This work is devoted to the role of different parameters governing the zeolite MTW crystallization process. The influence of the most important factors: the nature of the silica and alumina source, the type of the organic cation, the alkalinity of the reaction mixture and the crystallization temperature, was studied. The molar composition of the initial hydrogel was varied in other to determine the crystallization field of the zeolite MTW. The observed morphology and particle size of the crystallites are related to the corresponding reaction conditions. The competitive formation of the other zeolite types (prevalently MFI and BEA) is discussed.

    Stress corrosion cracking of alloy 600 in pure water is assumed to be the damaging process of a large number of small radius U-bends of PWR steam generators. The possible influencing parameters are reviewed. The determining factor is a too high level of stress arising from two main origins: residual stresses; and overstresses induced by the inner pressure in deformed cross sections. The latter have been assessed by two dimensional finite elements computation and by strain gages measurements. Stress corrosion tests in boiling MgCl2 sustain the previous results for outer surface overstresses. Geometrical characterizations were performed on: in service SG tubes by internal spherical gages; and laboratory samples by internal spherical gages, LVDT and ultrasonic measurements, cross sectioning

The cost of labour turnover of these key resources is high in both financial and non financial terms. There is thus a need to understand what the factors are that underpin the retention cognitions of knowledge workers. Data was collected from 306 knowledge workers in full time employment representing a wide range of demographic groupings. The results showed that job satisfaction and organisational commitment do not predict knowledge workers’ proposed future length of service.Factor analysis revealed seven underlying dimensions of retention cognitions. Cluster analysis revealed nine distinct clusters of knowledge workers with regard to their retention cognitions. High levels of individualism, need for challenge and focus on personal development were demonstrated. The implications of these findings are discussed.

    Full Text Available Hypertension is a common chronic disease in the elderly. This study aimed to determine the effects of age, ethnicity, gender, education, marital status, nutritional parameters, and blood elements on the risk of high blood pressure in the Malaysian elderly. This research was conducted on a group of 2322 non-institutionalized Malaysian elderly. The hierarchy binary logistic regression analysis was applied to estimate the risk of hypertension in respondents. Approximately, 45.61% of subjects had hypertension. The findings indicated that the female gender (Odds ratio (OR = 1.54, an increase in body weight (OR = 1.61, and an increase in the blood levels of albumin (OR = 1.51, glucose (OR = 1.92, and triglycerides (OR = 1.27 significantly increased the risk of hypertension in subjects (p < 0.05. Conversely, an increase in both dietary carbohydrates (OR = 0.74, and blood cholesterol level (OR = 0.42 significantly reduced the risk of hypertension in samples (p < 0.05. Furthermore, the results showed that ethnicity was a non-relevant factor to increase the risk of hypertension in subjects. It was concluded that female gender, an increase in body weight, and an increase in the blood levels of glucose, triglycerides, and albumin enhanced the risk of high blood pressure in the Malaysian elderly. In addition, an increase in both dietary carbohydrates and blood cholesterol level decreased hypertension in subjects.

    Full Text Available Objective: The increase in life quality and expectancy causes an increase in the elderly population. Improvements in burn treatment resulted in decreased mortality in children and young adults but in elderly patients burns are still an important trauma that should be handed differently than other age groups. The aim of this study was to evaluate the factors effecting mortality in patients with burns over 45 years old. Methods: Fifty-eight patients over 45 years of age, who were treated in our burns unit in the last 3 years were included in our study. Their age, burn percentage and depth, coexisting diseases and mortality rates were examined retrospectively. Results: The average age of surviving patients was 57.4 years while it was 70 years for nonsurviving patients (p=0.002. The width of burn area was 21.1 % in surviving and 50 % in nonsurviving patients (p<0.01. The effect of additional coexistent diseases on mortality was significant (p=0.001. The most common reasons of mortality were sepsis and congestive heart failure. Conclusion: We found out that the age, percentage of burns and coexistent diseases had a negative effect on success of treatment and mortality. Mortality rates will decrease in these cases with careful follow-up and a multidisciplinary approach. J Clin Exp Invest 2015; 6 (3: 240-243

    Full Text Available ABSTRACT: Vasectomy is one of the most effective but less utilized types of contraception method which could addresses the involvement of males to the family planning. The aim of the study was therefore to investigate the awareness about and practice of men towards vasectomy among workers in Dashen brewery, Ethiopia. Descriptive cross sectional study was conducted using pre tested self-administered questioner to assess the Knowledge, attitude and factors associated with low utilization of vasectomy. A total of 187 study participants were included to this study using single population proportion formula and random sampling technique. Majority of the participants 155 (82.9% never heard about vasectomy as a contraception method. Their knowledge about vasectomy is generally very poor as large proportion of respondents didn’t know how it works, its effectiveness and its effect on their sexual performance. None of the respondents have ever used vasectomy as a modern male contraception method. Misleading information towards its impact on sexual performance/desire was reported as a main reason not to use this method. Among others need of more children, unavailability of services, lack of information, spouse refusal and religious concerns were mentioned as a potential reasons for their negative perception towards vasectomy. Lack of awareness, myths and rumors, limited access to services, and indifference and bias on the part of providers about vasectomy limit its popularity in Ethiopia. Therefore, it is vital to introduce appropriate educational plan to increase awareness and usage of vasectomy in Ethiopia.

    Objective: To assess the quality and patient satisfaction in Endoscopy Unit of Shifa International Hospital. Study Design: Cross-sectional survey. Place and Duration of Study: Division of Gastroenterology, Shifa International Hospital, Islamabad, Pakistan, from July 2011 to January 2012. Methodology: Quality and patient satisfaction after the endoscopic procedure was assessed using a modified GHAA-9 questionnaire. Data was analyzed using SPSS version 16. Results: A total of 1028 patients were included with a mean age of 45 A+- 14.21 years. Out of all the procedures, 670 (65.17%) were gastroscopies, 181 (17.60%) were flexible sigmoidoscopies and 177 (17.21%) were colonoscopies. The maximum unsatisfactory responses were on the waiting time before the procedure (13.13 %), followed by unsatisfactory explanation of the procedure and answers to questions (7.58%). Overall, unsatisfied impression was 4.86%. The problem rate was 6.22%. Conclusion: The quality of procedures and level of satisfaction of patients undergoing a gastroscopy or colonoscopy was generally good. The factors that influence the satisfaction of these patients are related to communication between doctor and patient, doctor's manner and waiting time for the procedure. Feedback information in an endoscopy unit may be useful in improving standards, including the performance of endoscopists. (author)

    2016-09-01

    Smoking is a serious public health problem, and accurate real-time assessment of risk factors associated with smoking is critical to understanding smoking relapse. Negative affect is often described as a critical risk factor related to smoking relapse, and ecological momentary assessment (EMA) methods have been widely used to study real-time relations between negative affect and smoking. However, the factor structure of momentary negative affect ratings is unknown. The current investigation examined the multilevel factor structure and internal consistency of an EMA measure of negative affect. Daily assessments were collected for 1 week prequit and 3 weeks postquit from 113 adult daily smokers receiving nicotine replacement therapy and counseling to quit smoking. Results supported a 2-factor model with correlated but distinct agitation and distress factors, rather than a single-factor model of negative affect. The agitation factor was indicated by these items: impatient, tense/anxious, restless. The distress factor was indicated by these items: sad/depressed, upset, distressed. The 2-factor model had acceptable model fit and consistent factor loadings across 3 separate cessation phases: prequit, postquit with recent smoking, and postquit without recent smoking. The 2 factors were highly correlated, showed good internal consistency, and showed strong associations with theoretically relevant smoking and affect variables. Agitation was more strongly related to urge to smoke, and distress was more strongly related to recent stress. This study provides support for a 2-factor model of an EMA measure of negative affect and highlights distinct facets that may be useful for future investigations of affect and smoking.

    Jawoniyi, Oluwafunmilayo Ololade; Gormley, Kevin

    Organ and tissue dysfunction and failure cause high mortality rates around the world. Tissue and organs transplantation is an established, cost-effective, life-saving treatment for patients with organ failure. However, there is a large gap between the need for and the supply of donor organs. Acute and critical care nurses have a central role in the organ donation process, from identifying and assessing potential donors and supporting their families to involvement in logistics. Nurses with an in-depth knowledge of donation understand its clinical and technical aspects as well as the moral and legal considerations. Nurses have a major role to play in tackling organ and tissue shortages. Such a role cannot be adequately performed if nurses are not fully educated about donation and transplant. Such education could be incorporated into mandatory training and completed by all nurses. PMID:26153810

    Thirty-seven sets of crystallographic enzyme data were selected from Protein Data Bank (PDB, 1995). The average temperature factors (B) of the critical residues at the active site and the whole molecule of those enzymes were calculated respectively. The statistical results showed that the critical residues at the active site of most of the enzymes had lower B factors than did the whole molecules, indicating that in the crystalline state the critical residues at the active site of the natural enzymes possess more stable conformation than do the whole molecules. The flexibility of the active site during the unfolding by denaturing was also discussed.

  13. Analysis of factors affecting angle ANB.

    1984-05-01

    Cephalometric analyses based on angular and linear measurements have obvious fallacies, which have been discussed in detail by Moyers and Bookstein. However, the clinical application of such an analysis by the orthodontic profession in treatment planning is widely accepted. Variations of angle ANB are commonly used to determine relative jaw relationships in most of the cephalometric evaluations. Several authors, including points A and B influences angle ANB, as does rotational growth of the upper and lower jaws. In addition, the authors point out that growth in a vertical direction (distance N to B) and an increase of the dental height (distance A to B) may contribute to changes in angle ANB. For a Class I relation (Wits = 0 mm), a mathematical formula has been developed which enables the authors to study the geometric influence of angle ANB caused by the following four effects: (1) rotation of the jaws and/or occlusal plane relative to the anterior cranial base; (2) anteroposterior position of N relative to point B, (3) vertical growth (distance N to B); (4) increase in dental height (distance A to B). It was observed that, contrary to the common belief that an ANB angle of 2 +/- 3.0 degrees is considered normal for a skeletal Class I relation, the calculated values of angle ANB will vary widely with changes in these four controlling factors under the same skeletal Class I conditions (Wits = 0 mm). Therefore, in a case under consideration, angle ANB must be corrected for these geometric effects in order to get a proper perspective of the skeletal discrepancy. This is facilitated by comparing the measured ANB angle with the corresponding ANB angle calculated by a formula for a Class I relationship. The corresponding calculated angle ANB can be taken from the tables which are based upon the formula using the same values for SNB, omega (angle between occlusal plane and anterior cranial base), b (which is distance N to B) and a (dental height measured as perpendicular

  17. Factors affecting the next generation of nuclear power

    International Nuclear Information System (INIS)

    For both financial, environmental and health reasons, and because of external and internal factors affecting this nation's energy supply, nuclear power will likely play a part in supplying this nation's energy in the coming decades. I believe this to be true for some other parts of the world as well. Even some severe critics of the nuclear power industry and the NRC might agree with me on this point. Increasing concern with the environmental consequences of the burning of fossil fuels has led some former opponents of the use of nuclear power to balance anew the risks and benefits of nuclear power and to modify to some degree their former opposition. A related concern with the adequacy of the energy supply is leading others to modify their positions. According to analyses done by the U.S. Department of Energy, after 1994 the United States will no longer be able to assure all its citizens a reliable supply of electricity. Already, many areas of the country are in need of additional electric capacity. In both Sweden and Switzerland, similar concerns have led to the adoption by many of more compromising positions. Some critics of nuclear power may in the end still reject it as an alternative, but, with the increased pressures on the environment and on our energy supply, nuclear power is an alternative which cannot be rejected without the most serious consideration. This should be, I believe, a point of consensus among us. In sum, there is a future for nuclear power in the sense that there is a use for it

  18. Vapor-like liquid coexistence densities affect the extension of the critical point's influence zone

    Rivera, Jose Luis; Guerra-Gonzalez, Roberto

    2015-01-01

    The critical point affects the coexistence behavior of the vapor-liquid equilibrium densities. The length of the critical influence zone is under debate because for some properties, like shear viscosity, the extension is only a few degrees, while for others, such as the density order parameter, the critical influence zone range covers up to hundreds of degrees below the critical temperature. Here we show that for a simple molecular potential of ethane, the critical influence zone covers a wide zone of tens of degrees (below the critical temperature) down to a transition temperature, at which the apparent critical influence zone vanishes and the transition temperature can be predicted through a pressure analysis of the coexisting bulk liquid phase. The liquid phases within the apparent critical influence zone show low densities, making them behave internally like their corresponding vapor phases. Therefore, the experimentally observed wide extension of the critical influence zone is due to a vapor-like effect ...

    For a graph G =(V,E),a subset VS is a dominating set if every vertex in V is either in S or is adjacent to a vertex in S.The domination number γ(G) of G is the minimum order of a dominating set in G.A graph G is said to be domination vertex critical,if γ(G-v) < γ(G) for any vertex v in G.A graph G is domination edge critical,if γ(G ∪ e) < γ(G) for any edge e ∈/E(G).We call a graph G k-γ-vertex-critical(resp.k-γ-edge-critical) if it is domination vertex critical(resp.domination edge critical) and γ(G) = k.Ananchuen and Plummer posed the conjecture:Let G be a k-connected graph with the minimum degree at least k+1,where k 2 and k≡|V|(mod 2).If G is 3-γ-edge-critical and claw-free,then G is k-factor-critical.In this paper we present a proof to this conjecture,and we also discuss the properties such as connectivity and bicriticality in 3-γ-vertex-critical claw-free graph.

    International Nuclear Information System (INIS)

    The growing use of internet and online purchasing among young consumers in Malaysia provides a huge prospect in e-commerce market, specifically for B2C segment. In this market, if E-marketers know the web-based factors affecting online buyers' behaviour, and the effect of these factors on behaviour of online consumers, then they can develop their marketing strategies to convert potential customers into active one, while retaining existing online customers. Review of previous studies related to the online purchasing behaviour in B2C market has point out that the conceptualization and empirical validation of the online purchasing behaviour of Information and Communication Technology (ICT) literate users, or ICT professional, in Malaysia has not been clearly addressed. This paper focuses on (i) web-based factors which online buyers (ICT professional) keep in mind while shopping online; and (ii) the effect of web-based factors on online purchasing behaviour. Based on the extensive literature review, a conceptual framework of 24 items of five factors was constructed to determine web-based factors affecting online purchasing behaviour of ICT professional. Analysis of data was performed based on the 310 questionnaires, which were collected using a stratified random sampling method, from ICT undergraduate students in a public university in Malaysia. The Exploratory factor analysis performed showed that five factors affecting online purchase behaviour are Information Quality, Fulfilment/Reliability/Customer Service, Website Design, Quick and Details, and Privacy/Security. The result of Multiple Regression Analysis indicated that Information Quality, Quick and Details, and Privacy/Security affect positively online purchase behaviour. The results provide a usable model for measuring web-based factors affecting buyers' online purchase behaviour in B2C market, as well as for online shopping companies to focus on the factors that will increase customers' online purchase.

    We study the massless flows described by the staircase model introduced by Al.B. Zamolodchikov through the analytic continuation of the sinh-Gordon S-matrix, focusing on the renormalisation group flow from the tricritical to the critical Ising model. We show that the properly defined roaming limits of certain sinh-Gordon form factors are identical to the form factors of the order and disorder operators for the massless flow. As a by-product, we also construct form factors for a semi-local field in the sinh-Gordon model, which can be associated with the twist field in the ultraviolet limiting free massless bosonic theory.

    Mogk, D. W.; Geissman, J. W.

    2015-12-01

    There is a compelling need to develop the geoscience workforce of the future to address the "grand challenges" that face humanity. This workforce must have a strong understanding of Earth history, processes and materials and be able to communicate effectively and responsibly to inform public policy and personal and societal actions, particularly with regard to geohazards and natural resources. Curricula to train future geoscientists must be designed to help students develop critical thinking skills across the curriculum, from introductory to senior capstone courses. Students will be challenged in their pre-professional training as geoscientists as they encounter an incomplete geologic record, ambiguity and uncertainty in observed and experimental results, temporal reasoning ("deep time", frequency, recurrence intervals), spatial reasoning (from microns to mountains), and complex system behavior. Four instructional approaches can be combined to address these challenges and help students develop critical thinking skills: 1) Geoethics and ethical decision making includes review and integration of the context/facts of the situation, stakeholders, decision-makers, and possible alternative actions and expected outcomes; 2) The affective domain which encompasses factors such as student motivation to learn, curiosity, fear, attitudes, perceptions, social barriers and values; 3) Metacognition which encourages students to be aware about their own thinking processes, and to develop self-monitoring and self-regulating behaviors; and 4) Systems thinking which requires integrative thinking about the interactions between physical, chemical, biological and human processes, feedback mechanisms and emergent phenomena. Guided inquiry and scaffolded exercises can be used to present increasingly complex situations that require a thorough understanding of geologic principles and processes as applied to issues of societal concern. These approaches are not "owned" by any single course or

    2016-08-01

    While workers' safety risk tolerances have been regarded as a main reason for their unsafe behaviors, little is known about why different people have different risk tolerances even when confronting the same situation. The aim of this research is to identify the critical factors and paths that influence workers' safety risk tolerance and to explore how they contribute to accident causal model from a system thinking perceptive. A number of methods were carried out to analyze the data collected through interviews and questionnaire surveys. In the first and second steps of the research, factor identification, factor ranking and factor analysis were carried out, and the results show that workers' safety risk tolerance can be influenced by four groups of factors, namely: (1) personal subjective perception; (2) work knowledge and experiences; (3) work characteristics; and (4) safety management. In the third step of the research, hypothetical influencing path model was developed and tested by using structural equation modeling (SEM). It is found that the effects of external factors (safety management and work characteristics) on risk tolerance are larger than that of internal factors (personal subjective perception and work knowledge & experiences). Specifically, safety management contributes the most to workers' safety risk tolerance through its direct effect and indirect effect; while personal subjective perception comes the second and can act as an intermedia for work characteristics. This research provides an in-depth insight of workers' unsafe behaviors by depicting the contributing factors as shown in the accident causal model developed in this research. PMID:26775077

Furthermore, the large numbers of component deciding the competitiveness of contractors, whose organization structures and governance have turned out to be more muddled. Different construction companies have their own unique criteria which may differ from one to another. The enormous amount of issues needs to bring down to manageable numbers so that measures can be identified and scrutinized to enhance competitiveness. This paper discusses the result from the critical investigation from past studies in the Asian countries, namely China, India, Thailand, Singapore and Malaysia. Several fundamental factors have been identified as CSFs in construction companies in respective country. Also highlighted a critical survey based upon various literatures written on this subject where critical success factors (CSFs) as a yardstick to gauge the relationship among CSFs in various construction companies in the Asian region. Far reaching estimation of an organization's performance and resulting input to its supervision is crucial for business change. Estimation additionally empowers organizations to be contrasted from one another on the premise of institutionalized data, permitting best practices to be distinguished and connected more widely. Different countries have their own set of critical success factors (CSFs) which may differ in term of priority and at the same time share common elements of success factor in accomplishment as a construction companies.

  3. Factors affecting farm diversification in rice-wheat

    International Nuclear Information System (INIS)

    The risk in agriculture sector is due to various factors like weather and market conditions, particularly the demand of the commodities. This uncertainty can result in variable returns (farm income) to the decisions that farmers make in a particular season. Diversification is a frequently used risk management strategy that involves participation in more than one activity. It has the added advantage of mitigating price risk as well as fluctuations in outputs. The main purpose of this paper was to determine the factors affecting crop diversification. For determining the effect of different factors on diversification a multiple regression model was used. The values of Entropy index computed for measuring horizontal diversification were taken as dependent variable and different factors affecting diversification were taken as independent variables. The results showed that the main factors affecting diversification were size of land holding, age of respondent, education level of respondent, farming experience of respondent, off farm income of respondent, distance of farm from main road, distance of farm from main market and farm machinery.

    Woerndl, M.

    2008-01-01

    Full Text Available The rapid diffusion of the Internet and the emergence of various social constructs facilitated by Internet technologies are changing the drivers that define how marketing techniques are developed and refined. This paper identifies critical factors for viral marketing, an Internet-based ‘word-of-mouth’ marketing technique. Based on existing knowledge, five types of viral marketing factors that may critically influence the success of viral marketing campaigns are identified. These factors are the overall structure of the campaign, the characteristics of the product or service, the content of the message, the characteristics of the diffusion and, the peer-to-peer information conduit. The paper discusses three examples of viral marketing campaigns and identifies the specific factors in each case that influence its success. The paper concludes with a viral marketing typology differentiating between viral marketing communications, unintended viral marketing and commercial viral marketing. This is still a rapidly evolving area and further research is clearly needed to monitor new developments and make sense of the radical changes these developments bring to the market.

Patterns of care for metastatic breast cancer, for which no standard-of-care exists, were of particular interest.Methods: Relevant studies written in English, Italian, French, or Spanish, published in 2000 or later, were identified through MEDLINE and reviewed. Review articles and clinical trials were excluded; all observational studies and surveys were considered. Articles were reviewed for any discussion of patient characteristics, hospital/physician/insurance characteristics, psychosocial characteristics, and clinical characteristics affecting receipt of chemotherapy by breast cancer patients.Results: In general, factors associated with increased likelihood of receiving chemotherapy included younger age, being Caucasian, having good general health and few co-morbidities, having more severe clinical disease, having responded well to previous treatment, and having breast cancer that is estrogen- or progesterone-receptor-negative. Many of the clinical factors found to increase the likelihood of receiving chemotherapy were consistent with current oncology guidelines. Of the relevant 19 studies identified, only six (32% reported data specific to metastatic cancer; most studies aggregated women with stage I–IV for purposes of analysis.Conclusion: Studies of patterns of care in breast cancer treatment can help identify challenges in health care provided to particular subgroups of women and can aid researchers in designing studies that account for such factors in clinical and

    Background: Today, the use of information systems in health environments, like any other fields, is necessary and organizational managers are convinced to use these systems. However, managers’ satisfaction is not the only factor in successfully implementing these systems and failed information technology projects (IT) are reported despite the consent of the directors. Therefore, this study aims to determine the factors affecting the successful implementation of a hospital information system. Methods: The study was carried out as a descriptive method in 20 clinical hospitals that the hospital information system (HIS) was conducted in them. The clinical and paraclinical users of mentioned hospitals are the study group. 400 people were chosen as samples in scientific method and the data was collected using a questionnaire consisted of three main human, managerial and organizational, and technological factors, by questionnaire and interview. Then the data was scored in Likert scale (score of 1 to 5) and were analyzed using the SPSS software. Results: About 75 percent of the population were female, with average work experience of 10 years and the mean age was 30 years. The human factors affecting the success of hospital information system implementation achieved the mean score of 3.5, both organizational and managerial factors 2.9 and technological factors the mean of 3. Conclusion: Human factors including computer skills, perceiving usefulness and perceiving the ease of a hospital information system use are more effective on the acceptance and successful implementation of hospital information systems; then the technological factors play a greater role. It is recommended that for the successful implementation of hospital information systems, most of these factors to be considered PMID:27041811

    Full Text Available Background: Despite the positive impact of cardiac rehabilitation (CR on quality of life and mortality, the majority of people who could benefit from this program fail to participate in it. The lack of referral from the physician is a common reason that patients give for not seeking CR. The objective of this study was to compare factors affecting CR referral by cardiologists. Methods: A cross-sectional survey of 122 cardiologists, including 89 general cardiac specialists and 33 fellows in cardiology from 11 major cardiology training centers in Iran, was done in 2010. They responded to the 14- item investigator-generated survey, examining the physician’s attitudinal and knowledge factors affecting CR referral. Results: 47.9% of the subjects reported having available CR centers but only 6.6% reported continuous medical education on the topic. 90.7% of the physicians reported that less than 15% of patients are referred to CR centers. The main factor affecting the low referral rate was limited general knowledge about CR programs (79.5% such as program attributes and benefits, methods of reimbursement. Lack of insurance coverage, unavailability of CR centers in the community and low physicians’ fee were other factors reported by the physicians. Conclusion: Cardiologists’ inadequate general knowledge of and attitude toward CR programs seem to be a potential threat for cardiac prevention and rehabilitation in some societies.

    Full Text Available Abstract Background The choice between several treatment options for replacing a single missing tooth is influenced by clinical, dentist- and patient-immanent factors. This study aimed to determine the patient factors that would affect the treatment decision to replace a single missing tooth and to assess the satisfaction with several options. Method 200 volunteers involved (121 females and 79 males divided into four groups, Group A: consisted of patients with conventional fixed partial dentures or patients with resin bonded fixed partial dentures. Group B: consisted of patients who received removable partial dentures while Group C: consisted of patients who received a single implant supported crown, and a control group D: consisted of patients who received no treatment. Data were collected using a questionnaire. Results The highest percentage of males within groups (58% was within the removable prostheses category. The majority of the subjects in the study reported that the main reason for replacing a missing tooth was for esthetic and function. Most important factor affecting the choice between treatment modalities was damaging the neighboring teeth. Pain, post operative sensitivity and dental phobia were important factors in choosing the prosthesis type and affected the control group patients not to have any treatment. The highest satisfaction percentage among groups studied was recorded for dental implants then FPD groups, while the least percentage were in both the control and RPD groups, for all aspects of function, esthetic and speech efficiency. Conclusions The final choice between FPD, RPD and implant depended on several factors which affected the decision making; among these is cost and patients' awareness of the different treatment options.

    The factors driving the disparity in health outcomes between Indigenous and non-Indigenous Australians include socio-economic factors, racism, and history. The current study focused on exploring Indigenous participants' perspectives of the factors that affect the health behavior of their community members. Participatory action research methodology and a grounded theory approach were utilized. In total, 120 members of two urban West Australian Indigenous communities participated in focus group discussions. There was substantial similarity between the themes that emerged within the discussions held in the two communities. Factors relating to culture, social connections, racism, communication, and personal aspects were particularly salient to health behavior of the participants. Several of the themes including culture, racism, communication, and distrust highlight the tension caused by being a member of a minority cultural group that has been marginalized by the practices and attitudes of the dominant cultural group. Personal choice was sometimes prioritized over health. PMID:25847855

    Full Text Available In order to combat adverse effects of farmland degradation it is necessary for farmers to adopt sustainable land management and conservation strategies like intercropping and conservation tillage. However, efforts to adopt these strategies are very minimal in Ethiopia. In an attempt to address the objectives of examining factors affecting use of intercropping and conservation tillage practices, this study utilized plot- and household-level data collected from 211 farm households and employed a bivariate probit model for its analysis. The study revealed that intercropping and conservation tillage decisions are interdependent, and that they are also significantly affected by various factors. In addition, conservation tillage and intercropping practices as short- term interventions are found to augment the long-term interventions like terraces, diversion ditches, and tree plantations. The paper highlights important policy implications that are required to encourage intercropping and conservation tillage measures.

    The susceptibility or Alloy 22 (N06022) to crevice corrosion may depend on environmental or external factors and metallurgical or internal factors. Some of the most important environmental factors are chloride concentration, inhibitors, temperature and potential. The presence of a weld seam or second phase precipitation in the alloy are classified as internal factors. The localized corrosion resistance of Alloy 22 has been extensively investigated in the last five years, however not all affecting factors were considered in the studies. This paper discusses the current findings regarding the effect of many of these variables on the susceptibility (or resistance) of Alloy 22 to crevice corrosion. The effect of variables such as temperature, chloride concentration and nitrate are rather well understood. However there are only limited or no data regarding effect of other factors such as pH, other inhibitive or deleterious species and type of crevicing material and crevice geometry. There are contradictory results regarding the effect of metallurgical factors such as solution heat treatment.

    Contemporaneous theories of the etiology and treatment of sex offenders incorporate the notion that negative affect is causally related to sexually deviant behavior. Specifically, one current theory suggests that sex functions as a mechanism for alleviating negative affect among sex offenders. This paper critically reviews research examining the hypothesis that sex functions as a coping strategy among sex offenders as well as literature suggesting there is a causal relation among negative affect, deviant sexual fantasies, and sexual offending. Due to methodological limitations, the literature in this review does not support a causal relation between negative affect and sexual offending, or the hypothesis that sex functions to alleviate negative affect. Methodological strengths and weaknesses of this area of research are discussed and suggestions for future research are provided. PMID:20074840

    A systematic and comprehensive study of the retention of minority students enrolled in college-level engineering was conducted. The majority of prior work in this area focused on institutional retention factors for students in non-specified majors and considered students ``dropouts`` whenever there was a break in enrollment. This study looked only at students whose beginning major was engineering, enrolled primarily at historically black colleges and universities (HBCUs), including a comparison sample from a predominantly white institution (PWI). Science persisters were defined as those students who continuously enrolled in post-secondary institutions full- and part-time -- whether or not they transferred between institutions. The critical factor was their continued enrollment in engineering. Study participants provided four types of information: (1) a measure of academic motivation, (2) an objective measure of science interest, (3) a measure of nine aspects of normal personality functioning, and (4) an assessment of selected demographic variables. 64 refs.

    Borderline personality disorder (BPD) represents a significant therapeutic challenge. Critical factors in psychotherapeutic treatment of patients with BPD are noticeable and strictly related to the psychopathological dimensions of this disorder: affective and relational instability, behavioral impulsivity and precarious definition of identity. These features are emphasized by therapeutic intervention and become evident during the course of the treatment. Psychotherapeutic setting induces BPD patient to actualize the dysfunctional relational patterns that have been acquired during childhood. Specific critical factors concern the characteristics of the patient (risk of suicide, aggressive behaviors, chronic course of the disorder, disorganized attachment style), of the therapist (therapeutic skills, training, countertransference, risk of burnout) and of the setting of psychotherapy (patients selection, therapeutic alliance, need to set limits, duration and end of therapy). In Otto Kernberg's and Marsha Linehan's models of psychotherapy specific for DBP the authors identify substantially overlapping objectives and modalities of intervention. In particular, therapists should take care of patient safety, maintain boundaries of therapeutic setting and promote the development of psychotherapeutic process. The aim of this article is to analyze the main critical factors affecting psychotherapeutic process in patients with BPD. Objectives and priorities that therapist should consider to address these issues will be discussed. We will also try to make clear why interpersonal psychotherapy adapted to DBP can represent one of the therapeutic models that may be useful to manage and resolve these difficulties. PMID:27030345

    Uterine adenogenesis, a unique post-natal event in mammals, is vulnerable to endocrine disruption by estrogens and progestins resulting in infertility or reduced prolificacy. The absence of uterine glands results in insufficient transport of nutrients into the uterine lumen to support conceptus development. Arginine, a component of histotroph, is substrate for production of nitric oxide, polyamines and agmatine and, with secreted phosphoprotein 1, it affects cytoskeletal organization of trophectoderm. Arginine is critical for development of the conceptus, pregnancy recognition signaling, implantation and placentation. Conceptuses of ungulates and cetaceans convert glucose to fructose which is metabolized via multiple pathways to support growth and development. However, high fructose corn syrup in soft drinks and foods may increase risks for metabolic disorders and increase insulin resistance in adults. Understanding endocrine disrupters and dietary substances, and novel pathways for nutrient metabolism during pregnancy can improve survival and growth, and prevent chronic metabolic diseases in offspring.

    Full Text Available This study is the result of research whose purpose was to study the implementation process of integrated management systems, called ERP Enterprise Resource Planning in the business environment. This study, more specifically, tried to identify the variables in this process and that, somehow, made it easy or caused some type of difficulty implementing the system. Based on the mixed method approach (Creswell, 2003, the study was performed by means of the content analysis of technical and scientific publications about this theme and by means of a field research for data collection from primary sources. The content analysis was based on the per mile procedure by Bardin (1977, making it possible to identify critical factors that may be found in the implementation of ERP system projects. Primary data was collected from structured interviews with the managers in charge of the implementation of the system, in each of the 12 companies in different sectors of the economy and based in Brazil. Based on this information, it was possible to test the factors extracted from the content analysis and then develop a list of factors that may effectively influence the implementation process of the system. In order to recognize the possible relations between the selected factors, the Spearman (rsp correlation coefficient was applied and the multiple regression analysis was performed by means of the stepwise procedure. The purpose of the regression analysis was to determine the relation of the “Assessment of the Implementation” dependent variable with other dependent variables in the selected categories. The results of these analyses showed that the support of the top management, the communication process for the clear evidence of this support, the technical support of the ERP program provider together with the project team expertise, training and qualification processes of the team in the system operation are significantly correlated and relevant factors for a

    Full Text Available The level of delta-7-stigmastenol (D-7-stigmastenol contained in olive oil is a new criterion for oil quality, particularly its purity from adulteration with other seed oils. In this study, 79 olive samples were collected and analyzed from different areas of Palestine to study the factors affecting D-7-stigmastenol levels in the oil. These areas included the provinces of Jericho, Hebron, Bethlehem, Ramallah, Salfeet, Nablus, Jenin, Tulkarem and Qalqilyah. The study began in October 2007 and ended in July 2008. The following 11 factors were taken into consideration during sample collection: olive fly infection, topography, olive storage before pressing, geographical area, effect of olive seeds during oil extraction, effect of pressing temperature, presence of olive leaves during oil extraction, soil type, maturity index of the olive fruit, olive variety and oil preservation and storage in terms of storage container types. The results show that soil type, region, maturity index and olive fly infection are the main factors affecting D-7-stigmastenol. Pressing temperature, olive storage before pressing, olive variety and oil storage showed a moderate effect. Olive seeds, topography and presence of olive leaves had a negligible effect on D-7-stigmastenol levels in the oil.

    The anaerobic threshold (AT) is used to determine the exercise capacity in patients with heart failure and healthy subjects. To determine the factors affecting AT, we determined the AT in healthy subjects, and examined the factors that determine AT in healthy subjects. One hundred and sixteen healthy subjects (79 men and 37 women) performed on a bicycle a stepwise increasing submaximal exercise. During the work test the parameters usually used in the detection of AT (Vo2, Vco2, VE), blood pressure, heart rate and oxygen saturation were recorded by a computerized system every minute. AT was determined from changes in ventilation and gas-exchange. The fat index was calculated from height and body weight measured at the beginning of the ventilatory function test. A significant correlation was obtained between AT and age, AT and fat index, AT and %VC, AT and maximum heart rate during exercise, AT and recovery rate of heart rate after exercise, and AT and Vo2 at rest. In addition, we examined the relationship among the parameters in 4 groups according to sex and age (30-49; younger, 50-69; older), because sex and age affected most parameters. We found a significant correlation between AT and fat index (older men and women), AT and %VC (younger and older women), AT and Vo2 at rest (younger and older men). We considered that the main factors that determined AT in healthy subjects were age, sex, fat index, %VC and Vo2 at rest. PMID:1518183

    This study aimed to systematically review the articles on factors affecting sexual function during menopause. Searching articles indexed in Pubmed, Science Direct, Iranmedex, EMBASE, Scopus, and Scientific Information Database databases, a total number of 42 studies published between 2003 and 2013 were selected. Age, estrogen deficiency, type of menopause, chronic medical problems, partner's sex problems, severity of menopause symptoms, dystocia history, and health status were the physical factors influencing sexual function of menopausal women. There were conflicting results regarding the amount of androgens, hormonal therapy, exercise/physical activity, and obstetric history. In the mental-emotional area, all studies confirmed the impact of depression and anxiety. Social factors, including smoking, alcohol consumption, the quality of relationship with husband, partner's loyalty, sexual knowledge, access to health care, a history of divorce or the death of a husband, living apart from a spouse, and a negative understanding of women's health were found to affect sexual function; however, there were conflicting results regarding the effects of education, occupation, socioeconomic status, marital duration, and frequency of sexual intercourse.

  1. Critical design factors for sector transport maintenance in DEMO

    International Nuclear Information System (INIS)

    This paper mainly focuses on a sector transport maintenance scheme from the aspects of high plant availability. In this study, three different maintenance schemes are considered based on (1) the number of maintenance ports and (2) the insertion direction. The design study clarifies critical design factors and key engineering issues on the maintenance scheme: (1) how to support an enormous overturning force of the toroidal field coils in the large open port for sector transport and (2) define the transferring mechanism of sectors in the vacuum vessel. On reviewing these assessment factors, the sector transport using a limited number of horizontal maintenance ports is found to be a more realistic maintenance scheme. In addition, evaluating maintenance scenarios under high decay heat is proposed for the first time. The key design factors are the cool-down time in the reactor and the cooling method in the maintenance scheme to keep components under operational temperature. Based on one-dimensional heat conduction analysis, after one month cool-down time, each sector of SlimCS could be transported to the hot cell facility by gas cooling. (paper)

  12. Important factors affecting fault detection coverage in probabilistic safety assessment of digital instrumentation and control systems

    International Nuclear Information System (INIS)

    As digital instrumentation and control (I and C) systems are gradually introduced into nuclear power plants (NPPs), concerns about the I and C systems’ reliability and safety are growing. Fault detection coverage is one of the most critical factors in the probabilistic safety assessment (PSA) of digital I and C systems. To correctly estimate the fault detection coverage, it is first necessary to identify important factors affecting it. From experimental results found in the literature and the authors’ experience in fault injection experiments on digital systems, four system-related factors and four fault-related factors are identified as important factors affecting the fault detection coverage. A fault injection experiment is performed to demonstrate the dependency of fault detection coverage on some of the identified important factors. The implications of the experimental results on the estimation of fault detection coverage for the PSA of digital I and C systems are also explained. The set of four system-related factors and four fault-related factors is expected to provide a framework for systematically comparing and analyzing various fault injection experiments and the resultant estimations on fault detection coverage of digital I and C systems in NPPs.

  13. Extrinsic factors affecting accuracy of ultrasonic flowmeters for LMFBRs

    International Nuclear Information System (INIS)

    Assuming that ultrasonic flowmeters of suitable intrinsic accuracy are feasible, this report explores factors extrinsic to the flowmeter which affect the accuracy such as asymmetric flow profile, regions of high turbulence and thermal stratification. By integrating isovelocity flow profile maps, the predicted performance of various flowmeter configurations may be compared to experimental data. For the two pipe arrangements analyzed, the single diametral path flowmeter results were within 5 percent of true flow rate. Theoretical correction factors could reduce the error for the straight pipe but increased the error for asymmetrical flow. On the same pipe arrangements a four path ultrasonic flowmeter spaced for Gaussian integration gave less than 1 percent error. For more general conclusions a range of flow profiles produced by typical LMFBR piping arrangements must be analyzed

    1974-01-01

    Factors which affect the stability of light-induced atebrin fluorescence quenching activity in chloroplast membranes, a measure of the electron transport dependent formation of energy-linked H/sup +/ gradients, were investigated in vitro. Class II spinach chloroplast membranes were isolated and stored at 0 to 4/sup 0/C and aliquots were subsequently tested for their retention of energizing capacity. The main factors which increase the stability of this activity were found to be (a) isolation in a potassium-containing medium but storage in a sucrose medium containing a low concentration of electrolytes; (b) the presence of butylated hydroxytoluene (an antioxidant), and a protein such as bovine serum albumin to remove free fatty acids in the medium during storage. Under these conditions, the energization capacity of chloroplasts is retained for more than 40 days.

    Ever since the introduction of Cawthorne-Cooksey exercises, vestibular rehabilitation (VR) has been gaining popularity in the treatment of the dizzy patient. Numerous studies support the effectiveness of VR in improving balance/walking skills, eye-head coordination and the quality of life of the patient. Different rehabilitation protocols have been used to treat patients with peripheral and central vestibular disorders. Assessment of the patients' progress is based on the patients' selfperception of dizziness and their functional skills. Factors such as age, medication, time of onset of vertigo and home based VR have been evaluated on their effect on the rehabilitation's outcome. The aim of this review is to evaluate rehabilitation strategies and discuss the factors that affect the outcome. PMID:22526580

    The factors that influence the ultimate level of success or failure of systems development projects have received considerable attention in the academic literature. However, previous research has rarely targeted different instances of a common type of system within a homogeneous organisational sector. This paper presents the results of a survey of IM&T managers within Community Trusts to gain insights into the factors affecting the success of Community Information Systems. The results demonstrate that the most successful operational systems were thoroughly tested prior to implementation and enjoyed high levels of user and senior management commitment. Furthermore, it has been shown that there is a relationship between the level of organisational impact and systems success, with the most successful systems engendering changes to the host organisation's culture, level of empowerment and clinical working practices. In addition to being of academic interest, this research provides many important insights for practising IM&T managers. PMID:10747445

    Roux, Judi Ann

    Scientific literacy for our students and the possibilities for careers available in Science, Technology, Engineering, and Mathematics (STEM) areas are important topics for economic growth as well as global competitiveness. The achievement of students in science learning is dependent upon the science teachers' effectiveness and experienced science teachers depend upon relevant professional development experiences to support their learning. In order to understand how to improve student learning in science, the learning of science teachers must also be understood. Previous research studies on teacher professional development have been conducted in other states, but Minnesota science teachers comprised a new and different population from those previously studied. The purpose of this two-phase mixed methods study was to identify the current types of professional development in which experienced, Minnesota secondary science teachers participated and the factors that affect their participation in professional development activities. The mixed-methods approach s utilized an initial online survey followed by qualitative interviews with five survey respondents. The results of the quantitative survey and the qualitative interviews indicated the quality of professional development experiences and the factors which affected the science teachers' participation in professional development activities.

    Full Text Available Organizations are operating in a dynamic and turbulent environment. In these conditions, they have to make decisions for new problems or situations. Most of decisions are therefore non-programmed and unstructured, accompanied by risk and uncertainty. Moreover, the problems and situations are complex. All organizations are oriented towards group decisionmaking processes, as useful tools to cope with uncertainty and complexity. Apart from the necessity, companies are turning towards participatory processes also to benefit from the important advantages that these processes offer. Organizations have realized the importance of group decision-making processes to contribute to the creation of sustainable competitive advantages. Main objective of this paper is to show that group decision-making processes do not offer guarantee for good decisions, because the effectiveness of group is affected by many factors. So, the first thing done in this paper is discussing about the benefits and limitations that accompany the use of groups with decision-making purpose. Afterwards, we stop on the different factors that influence the group’s ability to make good decisions. The aim is to emphasize that regardless of the many advantages of groups, some factors as group size, type of communication within the group, leadership style, the norms, the differentiation of roles and statuses, cohesion and compliance degree should be the main elements to keep into consideration because they affect the effectiveness of group. In this regard, is discussed how such factors influence the quality of decision and then we try to draw some conclusions that can improve and make better and easier group decision-making processes.

    Full Text Available Objective. Identification of the weight and postmenstrual age (PMA at successful weaning of NCPAP in preterm neonates and the factors influencing the successful wean. Study Design. Retrospective review of 454 neonates ≤32 weeks of gestational age (GA who were placed on NCPAP and successfully weaned to room air was performed. Results. Neonates had a mean birth weight (BW of 1357±392 grams with a mean GA of 29.3±2.2 weeks. Neonates were weaned off NCPAP at mean weight of 1611±432 grams and mean PMA of 32.9±2.4 weeks. Univariate analysis showed that chorioamnionitis, intubation, surfactant use, PDA, sepsis/NEC, anemia, apnea, GER and IVH were significantly associated with the time to NCPAP wean. On multivariate analysis, among neonates that were intubated, BW was the only significant factor (<0.001 that was inversely related to time to successful NCPAP wean. Amongst non-intubated neonates, along with BW (<0.01, chorioamnionitis (<0.01, anemia (<0.0001, and GER (<0.02 played a significant role in weaning from NCPAP. Conclusion. Neonates were weaned off NCPAP at mean weight of 1611±432 grams and mean PMA of 32.9±2.4 weeks. BW significantly affects weaning among intubated and non-intubated neonates, though in neonates who were never intubated chorioamnionitis, anemia and GER also significantly affected the duration on NCPAP.

  3. Factors affecting interaction of radiocesium with freshwater solids Pt. 2

    International Nuclear Information System (INIS)

    The paper aims at the analysis of principal factors affecting the interaction of radiocesium with freshwater solids, important for the migration of radiocesium in rivers. Uptake and release of radiocesium by bottom sediment and suspended solids from a small stream were studied as a function of contact time during the uptake and release, of concentration of the solid phase and of temperature, using laboratory model experiments. Kinetics of the uptake were found to be significantly affected by temperature and concentration of the solid phase. The kinetics and the concentration effect can be quantitatively described using kinetic model of two parallel or consecutive reactions. Kinetic parameters for the model were determined. Distribution coefficient Kd is independent of sediment concentration in the range of 20-70mg·dm-3 but passes through a maximum at higher concentration values. Release of radiocesium absorbed on the freshwater solids was observed. The amount released decreased with increasing contact time of radiocesium with solid phase. Quantitative evaluation of the release revealed partial irreversibility of radiocesium uptake on the solids studied. Results obtained are compared with literature data and conclusions are drawn on the importance of the factors studied for modeling of radiocesium migration in rivers.

    To evaluate factors which affect the longevity of tunneled central venous catheters (T-CVCs). A retrospective study was conducted on 363 T-CVCs. We evaluated the relevant factors affecting the longevity of the T-CVCs, such as age, gender, indication for catheterization, site of entry vessel, diameter and type of T-CVC, catheter tip position, and underlying diseases. Of the 363 T-CVCs which had been inserted, 331 (91%) were placed through the right internal jugular vein (RIJV). The catheter tip position was the strongest predictor for the longevity of the T-CVC. The short limb of the catheter tip placed either at the cavoatrial junction (CA junction) or below the lower margin of the right main bronchus had a good prognosis. The vessel through which the T-CVC was placed significantly influenced the longevity of the T-CVC; the RIJV was associated with better results than the left internal jugular vein. Also, a split-type catheter was significantly associated with a better result. A two distinct and separate type T-CVC placed through the RIJV in which the short limb catheter tip position was at the level of the CA junction, significantly increased the longevity of T-CVCs.

  5. Multiple weather factors affect apparent survival of European passerine birds.

    Directory of Open Access Journals (Sweden)

    Volker Salewski

    Full Text Available Weather affects the demography of animals and thus climate change will cause local changes in demographic rates. In birds numerous studies have correlated demographic factors with weather but few of those examined variation in the impacts of weather in different seasons and, in the case of migrants, in different regions. Using capture-recapture models we correlated weather with apparent survival of seven passerine bird species with different migration strategies to assess the importance of selected facets of weather throughout the year on apparent survival. Contrary to our expectations weather experienced during the breeding season did not affect apparent survival of the target species. However, measures for winter severity were associated with apparent survival of a resident species, two short-distance/partial migrants and a long-distance migrant. Apparent survival of two short distance migrants as well as two long-distance migrants was further correlated with conditions experienced during the non-breeding season in Spain. Conditions in Africa had statistically significant but relatively minor effects on the apparent survival of the two long-distance migrants but also of a presumably short-distance migrant and a short-distance/partial migrant. In general several weather effects independently explained similar amounts of variation in apparent survival for the majority of species and single factors explained only relatively low amounts of temporal variation of apparent survival. Although the directions of the effects on apparent survival mostly met our expectations and there are clear predictions for effects of future climate we caution against simple extrapolations of present conditions to predict future population dynamics. Not only did weather explains limited amounts of variation in apparent survival, but future demographics will likely be affected by changing interspecific interactions, opposing effects of weather in different seasons, and

    The authors explore factors that affect electricity trade between enterprises in the US and Canada and the US and Mexico. They look to those underlying policy and institutional factors that affect the relative costs of producing electricity in the three countries. In particular, they consider six factors that appear to have a significant impact on electricity trade in North America: differences in the types of economic regulation of power leading to differences in cost recovery for wholesale and retail power and wheeling charges; changing regulatory attitudes, placing more emphasis on demand-side management and environmental concerns; differences in energy and economic policies; differences in national and subnational environmental policies; changing organization of electric power industries which may foster uncertainty, change historical relationships, and provide other potentially important sources of power for distribution utilities; and differences in the ability of enterprises to gain access to electric power markets because of restrictions placed on transmission access. In Section 2, the authors discuss the regulation of electricity trade in North America and provide an overview of the recent trading experience for electricity between Canada and the US and between Mexico and the US, including the volume of that trade over the past decade and existing transmission capacity between regions of the three countries. In Section 3, they look at the benefits that accrue to trading counties and what those benefits are likely to be for the three countries. The discussion in Section 4 centers on the relevant provisions of the Canada Free Trade Agreement and the proposed North American Free Trade Agreement. In Section 5, they set the stage for the discussion of policy and institutional differences presented in Section 6 by outlining differences in the organization of the electric power sectors of Canada, the US, and Mexico. The study is synthesized in Section 7.

    Background Cardiovascular diseases are a leading cause of morbidity and mortality in solid organ transplant recipients. In addition, low physical activity is a risk factor for cardiac and cerebrovascular complications. Objectives This study examined potential relationships between physical activity, health-related quality of life (HRQoL), risk factors for cardiovascular disease, and an exercise test in liver-graft recipients. Patients and Methods A total of 107 participants (62 men/45 women) who had received a liver transplantation (LT) at least 6 months previously were evaluated. Physical activity was assessed using three different questionnaires, while HRQoL was assessed using the medical outcomes study short form (SF)-36 questionnaire, and health behaviors were evaluated using the health behavior inventory (HBI). The exercise test was performed in a standard manner. Results Seven participants (6.5%) had a positive exercise test, and these individuals were older than those who had a negative exercise test (P = 0.04). A significant association between a negative exercise test and a higher level of physical activity was shown by the Seven-day physical activity recall questionnaire. In addition, HRQoL was improved in various domains of the SF-36 in participants who had a negative exercise test. No correlations between physical activity, the exercise test and healthy behaviors, as assessed via the HBI were observed. Conclusions Exercise test performance was affected by lower quality of life and lower physical activity after LT. With the exception of hypertension, well known factors that affect the risk of coronary artery disease had no effect on the exercise test results.

  8. A Study on Factors Affecting Airborne LiDAR Penetration

    2015-01-01

    Full Text Available This study uses data from different periods, areas and parameters of airborne LiDAR (light detection and ranging surveys to understand the factors that influence airborne LiDAR penetration rate. A discussion is presented on the relationships between these factors and LiDAR penetration rate. The results show that the flight height above ground level (AGL does not have any relationship with the penetration rate. There are some factors that should have larger influence. For example, the laser is affected by a wet ground surface by reducing the number of return echoes. The field of view (FOV has a slightly negative correlation with the penetration rate, which indicates that the laser incidence angle close to zero should achieve the best penetration. The vegetation cover rate also shows a negative correlation with the penetration rate, thus bare ground and reduced vegetation in the aftermath of a typhoon also cause high penetration rate. More return echoes could be extracted from the full-waveform system, thereby effectively improving the penetration rate. This study shows that full-waveform LiDAR is an effective method for increasing the number of surface reflected echoes. This study suggests avoiding LiDAR survey employment directly following precipitation to prevent laser echo reduction.

    Maintaining good health is essential for touring musicians and singers. The stressful demands of touring may impact food choices, leading to detrimental effects on health and performance. This exploratory pilot study aimed to assess factors affecting healthful eating of touring musicians and singers. A 46-item survey was used to assess food- and nutrition-related attitudes, knowledge and behaviors, and environmental factors, as well as lifestyle, musical background, and demographic data. Participants (n=35) were recruited from a musicians' assistance foundation as well as touring musical theater productions and a music festival. Results indicate that touring musicians and singers had positive attitudes regarding healthful foods. Of 35 respondents, 80.0% indicated eating healthful food was important to them. Respondents reported feeling confident selecting (76.5%) and preparing (82.4%) healthful foods; however, they showed uncertainty when determining if carbohydrate-containing foods should be consumed or avoided. Respondents indicated environmental factors including availability and cost of healthy food options and tour schedules limited access to healthful foods. Venues (73.5%), fast food restaurants (67.6%), and airports (64.7%) were the most frequently identified locations in need of offering more healthful food choices. Respondents (52.9%) indicated more support from others while touring would help them make healthier food choices. More research is needed to develop mobile wellness programs as well as performance-based nutrition guidelines for musicians and singers that address the unique demands associated with touring.

    Biogenic amines (BAs) are molecules, which can be present in foods and, due to their toxicity, can cause adverse effects on the consumers. BAs are generally produced by microbial decarboxylation of amino acids in food products. The most significant BAs occurring in foods are histamine, tyramine, putrescine, cadaverine, tryptamine, 2-phenylethylamine, spermine, spermidine, and agmatine. The importance of preventing the excessive accumulation of BAs in foods is related to their impact on human health and food quality. Quality criteria in connection with the presence of BAs in food and food products are necessary from a toxicological point of view. This is particularly important in fermented foods in which the massive microbial proliferation required for obtaining specific products is often relater with BAs accumulation. In this review, up-to-date information and recent discoveries about technological factors affecting BA content in foods are reviewed. Specifically, BA forming-microorganism and decarboxylation activity, genetic and metabolic organization of decarboxylases, risk associated to BAs (histamine, tyramine toxicity, and other BAs), environmental factors influencing BA formation (temperature, salt concentration, and pH). In addition, the technological factors for controlling BA production (use of starter culture, technological additives, effects of packaging, other non-thermal treatments, metabolizing BA by microorganisms, effects of pressure treatments on BA formation and antimicrobial substances) are addressed.

  11. Factors Affecting Detection Probability of Acoustic Tags in Coral Reefs

    Acoustic telemetry is an important tool for studying the movement patterns, behaviour, and site fidelity of marine organisms; however, its application is challenged in coral reef environments where complex topography and intense environmental noise interferes with acoustic signals, and there has been less study. Therefore, it is particularly critical in coral reef telemetry studies to first conduct a long-term range test, a tool that provides informa- tion on the variability and periodicity of the transmitter detection range and the detection probability. A one-month range test of a coded telemetric system was conducted prior to a large-scale tagging project investigating the movement of approximately 400 fishes from 30 species on offshore coral reefs in the central Red Sea. During this range test we determined the effect of the following factors on transmitter detection efficiency: distance from receiver, time of day, depth, wind, current, moon-phase and temperature. The experiment showed that biological noise is likely to be responsible for a diel pattern of -on average- twice as many detections during the day as during the night. Biological noise appears to be the most important noise source in coral reefs overwhelming the effect of wind-driven noise, which is important in other studies. Detection probability is also heavily influenced by the location of the acoustic sensor within the reef structure. Understanding the effect of environmental factors on transmitter detection probability allowed us to design a more effective receiver array for the large-scale tagging study.

    Full Text Available BACKGROUND AND AIMS Increased intra-abdominal pressure (IAP, also referred to as intra-abdominal hypertension (IAH, affects organ function in critically ill patients. The prevalence of IAH is between 32% - 65% in intensive care units. Normal IAP is ≈ 5–7 mmHg. According to WSACS definition, IAH = IAP ≥12 mmHg and is divided into 4 grades. They are Grade I (12-15 mmHg, Grade II (16-20 mmHg, Grade III (21-25 mmHg, Grade IV (>25 mmHg. Transvesical measurement of IAP currently is the most popular technique. Several systems with or without the need for electronic equipment are available that allow IAP measurement. The aim is to study the incidence of IAH in critically ill patients, to assess the risk factors for development of IAH, to study the role of IAH as a risk factor for Acute Kidney Injury (AKI, to assess the role of IAH as a risk factor for increased (Intensive Care Unit ICU mortality. SUBJECTS AND METHODS This is a prospective observational study. Study period was six months. The study included 52 patients admitted to Medical ICU in Government Medical College, Kozhikode, Kerala. RESULTS AND CONCLUSION There was a very high incidence of intra-abdominal hypertension in critically ill patients. IAH was significantly associated with risk factors like sepsis, mechanical ventilation, pancreatitis, capillary leak, ascites, cumulative fluid balance and cirrhosis. IAH is an independent risk factor for development of acute kidney injury. IAH is an independent predictor of mortality in critically ill patients.

    Drug abuse has been widely linked to suicide risk. We examined the factors that affect adolescent drug users' suicide attempts in South Korea. This study analyzed the data of 311 adolescents who had used drugs such as inhalants, psychotropic drugs, and marijuana (195 males and 116 females). Among 311 subjects, 109 (35.0%) had attempted suicide during the last 12 months. After adjusting for other variables, depressive mood (OR=19.79) and poly-drug use (OR=2.79), and low/middle levels of academic achievement compared with a high level (OR=3.72 and 4.38) were independently associated with increased odds of a suicide attempt, while better perceived health (OR=0.32) was independently associated with reduced odds of a suicide attempt. For adolescent drug users, preventive work should be directed toward the active treatment of drug use, depression, and physical health and reinforcing proper coping strategies for academic and other stress.

    Full-waveform LIDAR is a technology which enables the analysis of the 3-D structure and arrangement of objects. An in-depth understanding of the factors that affect the shape of the full-waveform signal is required in order to extract as much information as possible from the signal. A simple model of LIDAR propagation has been created which simulates the interaction of LIDAR energy with objects in a scene. A 2-dimensional model tree allows controlled manipulation of the geometric arrangement of branches and leaves with varying spectral properties. Results suggest complex interactions of the LIDAR energy with the tree canopy, including the occurrence of multiple bounces for energy reaching the ground under the canopy. Idealized sensor instrument response functions incorporated in the simulation illustrate a large impact on waveform shape. A waveform recording laser rangefinder has been built which will allow validation or model results; preliminary collection results are presented here.

    Child mortality is a composite indicator reflecting economic, social, environmental, healthcare services, and their delivery situation in a country. Globally, Pakistan has the third highest burden of fetal, maternal, and child mortality. Factors affecting child mortality in Pakistan are investigated by using Binary Logistic Regression Analysis. Region, education of mother, birth order, preceding birth interval (the period between the previous child birth and the index child birth), size of child at birth, and breastfeeding and family size were found to be significantly important with child mortality in Pakistan. Child mortality decreased as level of mother's education, preceding birth interval, size of child at birth, and family size increased. Child mortality was found to be significantly higher in Balochistan as compared to other regions. Child mortality was low for low birth orders. Child survival was significantly higher for children who were breastfed as compared to those who were not. PMID:27354000

    Full Text Available In this paper we explore factors potentially affecting the size of Albanian insurance market, over the period 1999 to 2009. The results of co- integration regression show that GDP and fraction urban population, both one lagged value, size of population and paid claims, both at contemporary value, have significant positive effect on aggregate insurance premium in Albania while the market share of the largest company in the insurance market, one lagged value, has significant negative effect on aggregate insurance premiums. Granger causality test shows statistically significance contribution of GDP growth to insurance premium growth, GDP drives insurance premium growth but not vice versa. The Albanian insurance market is under development, indicators as: insurance penetration, premium per capita, ect are still at low level and this can justify the insignificant role of the insurance in the economy

  6. A quantitative study on important factors of the PSA of safety-critical digital systems

    International Nuclear Information System (INIS)

    This paper quantitatively presents the effects of important factors of the probabilistic safety assessment (PSA) of safety-critical digital systems. The result which is quantified using fault tree analysis methodology shows that these factors remarkably affect the system safety. In this paper we list the factors which should be represented by the model for PSA. Based on the PSA experience, we select three important factors which are expected to dominate the system unavailability. They are the avoidance of common cause failure, the coverage of fault tolerant mechanisms and software failure probability. We quantitatively demonstrate the effect of these three factors. The broader usage of digital equipment in nuclear power plants gives rise to the safety problems. Even though conventional PSA methods are immature for applying to microprocessor-based digital systems, practical needs force us to apply it because the result of PSA plays an important role in proving the safety of a designed system. We expect the analysis result to provide valuable feedback to the designers of digital safety-critical systems

    In order to avoid harmful conditions, freshwater unionids are able to close their valves and to resist extended long periods of complete anoxia. Xenobiotics and diverse abiotic and biotic factors can change the rhythm of valve movements and thus affect the accumulation of heavy metals in these bivalves. When bivalves are used a bioindicators in the field and when the accumulation of toxicants are studied under the laboratory conditions, the effects of valve movements and shell closure have to be involved. In this study, the authors have recorded valve movements of two different unionid species (Anodonta anatina, Unio tumidus) in the field and in the laboratory using a digital monitoring system. Several experimental arrangements were compared (caged mussels vs. sediment dwelling mussels, flow-through vials vs. static aquaria with and without sediment). Some parameters of the mussel hemolymph, such as electrolytes, gases and acid base status, were compared with the results on the valve activity (time with valves open, number of adductions). The natural valve activity of the two unionid species differed clearly. In the field, effects of transfer and caging were found, and in the laboratory, sediment and water flow changed their behavior. The level of the blood oxygen was most affected, whereas, the acid-base status and the concentrations of electrolytes were effectively regulated by the unionids. The correlation between valve movements and the hemolymph parameters was weaker than expected.

    2014-01-01

    In this work we analyze the longitudinal instabilities of propagating acceleration structures that are driven by a relativistically intense laser at the moving plasma critical layer [1]. These instabilities affect the energy-spectra of the accelerated ion-beams in propagating critical layer acceleration schemes [2][3]. Specifically, using analytical theory and PIC simulations we look into three fundamental physical processes and their interplay that are crucial to the understanding of energy spectral control by making the laser-plasma ion accelerators stable. The interacting processes are (i) Doppler-shifted ponderomotive bunching [1][4] (ii) potential quenching by beam-loading [2] and (iii) two-stream instabilities. These phenomenon have been observed in simulations analyzing these acceleration processes [5][6][7]. From the preliminary models and results we present in this work, we can infer measures by which these instabilities can be controlled [8] for improving the energy-spread of the beams.

  11. Factors affecting job satisfaction among the radiologic technologists

    International Nuclear Information System (INIS)

    Job satisfaction is very important for adequate manpower management in the medical field. To study job satisfaction among the radiologic technologists, 344 cases were reviewed in five university hospitals and one general hospital. Self-administered questionnaire was used to study their socioeconomic characteristics, working conditions, job satisfaction, and the factors affecting there job satisfaction. The results were as follows : 1. There was statistically significant difference in job satisfaction according to the their department of employment, position, and hospital characteristics. 2. The group that was satisfied with their salary had a higher job satisfaction score, whereas others who were not satisfied ranked lower. 3. The positive answering group on the ability and job recognition ranked higher score on the job satisfaction than the negative answering group. 4. The group that was in good relationship with their superiors and co-workers scored higher on job satisfaction. From the above results, the job satisfaction was high for the group with positive thinking and reply, but the intentin to change their job was low. Considering the fact that these results represent only 6 hospitals from limited arease, therefore, necessary to include more medical facilities nationwide, especially small-medium sized clinics or hospitals where the difficulty with high turnover rate of employment is expected, to study further various factors involving job satisfaction in the future

  12. The exogenous factors affecting the cost efficiency of power generation

    International Nuclear Information System (INIS)

    This paper employs a stochastic frontier analysis (SFA) to examine cost efficiency and scale economies in Taiwan Power Company (TPC) by using the panel data covering the period of 1995-2006. In most previous studies, the efficiency estimated by the Panel Data without testing the endogeneity may bring about a biased estimator resulting from the correlation between input and individual effect. A Hausman test is conducted in this paper to examine the endogeneity of input variables and thus an appropriate model is selected based on the test result. This study finds that the power generation executes an increasing return to scale across all the power plants based on the pooled data. We also use installed capacity, service years of the power plant, and type of fuel as explanatory variable for accounting for the estimated cost efficiency of each plant by a logistic regression model to examine the factor affecting the individual efficiency estimates. The results demonstrate that the variable of installed capacity keeps a positive relationship with cost efficiency while the factor of working years has a negative relationship.

  13. Factors affecting RAIU in hyperthyroidism patients: an analysis

    International Nuclear Information System (INIS)

    Objective: To analyze the factors affecting thyroid radioiodine uptake (RAIU) of hyperthyroidism patients. Methods; RAIU was performed in 106 hyperthyroidism patients. Some factors were studied to analyze influences on the peak of RAIU, including patients' age and sex, gland weight, taking antithyroid drugs (ATD) or not, time of ATD taking and withdrawal. Results: Patients' RAIU peak had no significant difference for different ages and sex (F=1.68, P=0.1439). If preparation was performed according to the requirements before RAIU measurement, taking ATD or not had no influence on RAIU (t=1.1362, P=0.2625). RAIU peak was different between patients whose gland weight was ≤ 30 g and >30 g. Conclusions: Age and sex have no influence on RAIU. As long as ATD was discontinued at least one week before RAIU measurement, time of taking ATD and discontinuation have no influence on RAIU, and the result of measurement coincide with that of patients who do not take medicine. RAIU peak has relation with gland weight, and RAIU of people with gland weight ≤30 g was lower than that of people with gland weight >30 g

  14. Factors affecting production rates of cosmogenic nuclides in extraterrestrial matter

    Reedy, R. C.

    2015-10-01

    Good production rates are needed for cosmic-ray-produced nuclides to interpret their measurements. Rates depend on many factors, especially the pre-atmospheric object's size, the location of the sample in that object (such as near surface or deep inside), and the object's bulk composition. The bulk composition affects rates, especially in objects with very low and very high iron contents. Extraterrestrial materials with high iron contents usually have higher rates for making nuclides made by reactions with energetic particles and lower rates for the capture of thermal neutrons. In small objects and near the surface of objects, the cascade of secondary neutrons is being developed as primary particles are being removed. Deep in large objects, that secondary cascade is fully developed and the fluxes of primary particles are low. Recent work shows that even the shape of an object in space has a small but measureable effect. Work has been done and continues to be done on better understanding those and other factors. More good sets of measurements in meteorites with known exposure geometries in space are needed. With the use of modern Monte Carlo codes for the production and transport of particles, the nature of these effects have been and is being studied. Work needs to be done to improve the results of these calculations, especially the cross sections for making spallogenic nuclides.

    Full Text Available Elderly population is hospitalized more frequently than young people, and they suffer from more severe diseases that are difficult to diagnose and treat. The present study aimed to investigate the factors affecting mortality in elderly patients hospitalized for nonmalignant reasons. Demographic data, reason for hospitalization, comorbidities, duration of hospital stay, and results of routine blood testing at the time of first hospitalization were obtained from the hospital records of the patients, who were over 65 years of age and hospitalized primarily for nonmalignant reasons. The mean age of 1012 patients included in the study was 77.8 ± 7.6. The most common reason for hospitalization was diabetes mellitus (18.3%. Of the patients, 90.3% had at least a single comorbidity. Whilst 927 (91.6% of the hospitalized patients were discharged, 85 (8.4% died. Comparison of the characteristics of the discharged and dead groups revealed that the dead group was older and had higher rates of poor general status and comorbidity. Differences were observed between the discharged and dead groups in most of the laboratory parameters. Hypoalbuminemia, hypertriglyceridemia, hypopotassemia, hypernatremia, hyperuricemia, and high TSH level were the predictors of mortality. In order to meet the health necessities of the elderly population, it is necessary to well define the patient profiles and to identify the risk factors.

    Full Text Available Problem statement: 40-year history of agricultural production cooperatives in the country shows that this type of exploitation system has faced many ups and downs during this period. First, despite the help and support by the government, the cooperative sector has not been able to play a major role in the development of the country and its share has not exceeded 3% of development program. The main aim of this study is identifying the factors affecting the participation of Shirvan-Chardavol township’s agricultural cooperatives’ members. Approach: This casual comparative applied research which uses survey method for data accumulation, is of Quasi-experimental research type because of impossibility of controlling the research variables. A researcher-made questionnair was used as the main tool for gathering data. The face and content validity of the questionnaire were confirmed by a group of university professors and cooperative experts; also the reliability of the questionnaire was confirmed through calculating the Kronbach alfa coefficient (a = 0.80.

    Despite extensive effort during the past few decades, a comprehensive understanding of the key variables governing the electrochemical properties of cathode materials in Li-ion batteries is still far from complete. To elucidate the critical parameters affecting energy density (ED) and capacity (Q) retention in layer and spinel cathodes, we data-mine the existing experimental data via confirmatory factor analysis (CFA) based on a structural equation model (SEM), which is a proven, versatile tool in understanding complex problems in the social science. The data sets are composed of 18 and 15 parameters extracted from 38 layer and 33 spinel compounds, respectively. CFA reveals the irrelevance of Q retention to all the parameters we adopt, but it also reveals the sensitive variations of ED with specific parameters. We validate the usefulness of CFA in material science and pinpointed critical parameters for high-ED cathodes, hoping to suggest a new insight in materials design.

    The extent of outdoor exposure during winter and factors affecting it were examined in a cross-sectional population study in Finland. Men and women aged 25-74 years from the National FINRISK 2002 sub-study ( n=6,591) were queried about their average weekly occupational, leisure-time and total cold exposure during the past winter. The effects of gender, age, area of residence, occupation, ambient temperature, self-rated health, physical activity and education on cold exposure were analysed. The self-reported median total cold exposure time was 7 h/week (8 h men, 6 h women),leisure time and 1 h/week (1 h men, 1.5 h women) while commuting to work. Factors associated with increased occupational cold exposure among men were: being employed in agriculture, forestry and industry/mining/construction or related occupations, being less educated and being aged 55-64 years. Factors associated with increased leisure-time cold exposure among men were: employment in industry/mining/construction or related occupations, being a pensioner or unemployed, reporting at least average health, being physically active and having college or vocational education. Among women, being a housewife, pensioner or unemployed and engaged in physical activity increased leisure-time cold exposure, and young women were more exposed than older ones. Self-rated health was positively associated with leisure time cold exposure in men and only to a minor extent in women. In conclusion, the subjects reported spending 4% of their total time under cold exposure, most of it (71%) during leisure time. Both occupational and leisure-time cold exposure is greater among men than women.

    Full Text Available Globally, the responsible factors for the ongoing development of urbanization are the high speed of population growth, and the mass migration of humans to cities and large urban areas. In most countries, this process resulted in the emergence of ‘pseudo-urbanization’ which is difficult to be regulated. The purpose of the carried researches to determine the development priorities in the territory of Greater Baku – the capital city of the Republic of Azerbaijan; to define the problems that take place in this connection; and to develop ways of elimination of these problems. The reason of taking Baku as a research area is connected with some of the factors. Firstly, studies on Baku have been conducted based on the Soviet geographical and urban planning school and their methods for a long period. In this regard, it is necessary to carry out research in this field based on the principles adopted in most countries. Secondly, since 1992, the intensive accumulation of population in the territory of the capital city and the surrounding areas is being observed because of socio-economic problems. As a result, the process of pseudo-urbanization intensified, entailing a densely-populated area. Thirdly, low-rise buildings still continue to exist in the large areas within the territory of Baku, and they are not associated with the functional structure of the city. This situation creates many challenges, particularly in terms of density growth and effective use of the city’s territory. Finally, numerous new buildings have been constructed in the residential areas of Baku in recent years, and this may entailserious problems in water supply, energy provision, and utilities. The study is carried out referring to previous works of researchers, statistic data, and the results of the population census conducted in 1959-2009.The practical significance of the scientific work is that positive and negative factors affecting the further development of Greater Baku

    Identifying causes of declines and evaluating effects of management practices on persistence of local populations of burrowing owls (Athene cunicularia) requires accurate estimates of abundance and population trends. Moreover, regulatory agencies in the United States and Canada typically require surveys to detect nest burrows prior to approving developments or other activities in areas that are potentially suitable for nesting burrowing owls. In general, guidelines on timing of surveys have been lacking and surveys have been conducted at different times of day and in different stages of the nesting cycle. We used logistic regression to evaluate 7 factors that could potentially affect probability of a surveyor detecting a burrowing owl nest. We conducted 1,444 detection trials at 323 burrowing owl nests within 3 study areas in Washington and Wyoming, USA, between February and August 2000-2002. Detection probability was highest during the nestling period and increased with ambient temperature. The other 5 factors that we examined (i.e., study area, time of day, timing within the breeding season, wind speed, % cloud cover) interacted with another factor to influence detection probability. Use of call-broadcast surveys increased detection probability, even during daylight hours when we detected >95% of owls visually. Optimal timing of surveys will vary due to differences in breeding phenology and differences in nesting behavior across populations. Nevertheless, we recommend ???3 surveys per year: one that coincides with the laying and incubation period, another that coincides with the early nestling period, and a third that coincides with the late nestling period. In northern latitudes, surveys can be conducted throughout the day.

    Full Text Available This paper presents findings on the critical factors which affect the delivery of low-income housing in South Africa and the effect of these factors on the residents’ satisfaction with their housing units. Data used in the study was obtained through a Delphi Study, where the views of housing experts were solicited on the critical factors which affect low-income housing delivery in South Africa. Since panellists form the cornerstone of the Delphi Technique, clear inclusion criteria were applied and also as a means of evaluating the results and establishing the study’s potential relevance to other settings and populations. Hence, each expert was required to meet at least five benchmarks. These include the length of residency in South Africa, educational background amongst others. Results emanating from the study revealed that seven factors were considered critical by the experts after consensus was achieved. Amongst these include: limited budget (dwindling tax base and the lack of appropriate policy to handle informal settlement upgrading, etc. The study contributes to the body of knowledge on the subject where no consensus has been reached pertaining to the critical factors affecting the delivery of low-income housing in South Africa. A limitation of the study was the reliance on a structured questionnaire survey in the three iterative rounds of Delphi technique to reach consensus and experts were not allowed to add any more indicators.

    2011-07-01

    A review of the nursing literature reveals many undergraduate nursing students lack proficiency with basic mathematical skills, those necessary for safe medication preparation and administration. Few studies exploring the phenomenon from the undergraduate nursing student perspective are reported in the nursing literature. The purpose of this study was to explore undergraduate nursing students’ perceptions of math abilities, factors that affect math abilities, the use of math in nursing, and the extent to which specific math skills were addressed throughout a nursing curriculum. Polya’s Model for Problem Solving and the Bloom’s Taxonomy of Educational Objectives, Affective Domain served as the theoretical background for the study. Qualitative and quantitative methods were utilized to obtain data from a purposive sample of undergraduate nursing students from a private university in western Pennsylvania. Participants were selected based on the proficiency level with math skills, as determined by a score on the Elsevier’s HESI™ Admission Assessment (A2) Exam, Math Portion. Ten students from the “Excellent” benchmark group and eleven students from the “Needing Additional Assistance or Improvement” benchmark group participated in one-on-one, semi-structured interviews, and completed a 25-item, 4-point Likert scale survey that rated confidence levels with specific math skills and the extent to which these skills were perceived to be addressed in the nursing curriculum. Responses from the two benchmark groups were compared and contrasted. Eight themes emerged from the qualitative data. Findings related to mathematical approach and confidence levels with specific math skills were determined to be statistically significant.

  6. Factors Affecting Prostate Volume Estimation in Computed Tomography Images

    International Nuclear Information System (INIS)

    The aim of this study was to investigate how apex-localizing methods and the computed tomography (CT) slice thickness affected the CT-based prostate volume estimation. Twenty-eight volunteers underwent evaluations of prostate volume by CT, where the contour segmentations were performed by three observers. The bottom of ischial tuberosities (ITs) and the bulb of the penis were used as reference positions to locate the apex, and the distances to the apex were recorded as 1.3 and 2.0 cm, respectively. Interobserver variations to locate ITs and the bulb of the penis were, on average, 0.10 cm (range 0.03-0.38 cm) and 0.30 cm (range 0.00-0.98 cm), respectively. The range of CT slice thickness varied from 0.08-0.48 cm and was adopted to examine the influence of the variation on volume estimation. The volume deviation from the reference case (0.08 cm), which increases in tandem with the slice thickness, was within ± 3 cm3, regardless of the adopted apex-locating reference positions. In addition, the maximum error of apex identification was 1.5 times of slice thickness. Finally, based on the precise CT films and the methods of apex identification, there were strong positive correlation coefficients for the estimated prostate volume by CT and the transabdominal ultrasonography, as found in the present study (r > 0.87; p < 0.0001), and this was confirmed by Bland-Altman analysis. These results will help to identify factors that affect prostate volume calculation and to contribute to the improved estimation of the prostate volume based on CT images.

    Full Text Available Background: Multiple sclerosis (MS is a demyelinating disease which can cause many disabilities for the patient. Recent data suggests that MS patients have higher risk for osteoporosis. This study was performed to investigate if the osteoporosis prevalence is higher in MS patients and to determine the possible factors affecting bone mineral density (BMD.Methods: 51 definite relapsing-remitting MS patients according to McDonald's criteria (45 females, 6 males aged between 20 and 50 years participated in this study. The control group included 407 females aged from 20 to 49 years; they were healthy and had no history of the diseases affecting bone metabolism. Femoral and lumbar BMD were measured by Dual Energy X-ray Absorptiometry (DXA. The disability of MS patients was evaluated by Expanded Disability Status Scale (EDSS. The patient’s quality of life was evaluated by the validated Persian version of multiple sclerosis impact scale (MSIS-29.Results: Patients’ mean age was 36 ± 3.3 years and their mean disease duration was 8.7 ± 1.7 years. The mean EDSS score and the mean body mass index (BMI of the patients were 3 ± 0.9 and 23.5 ± 2.3 kg/m2, respectively. 29% of the patients had never been treated by ß-interferon and 6% of them had not received glucocorticoids (GCs pulses since their MS had been diagnosed. 26% of the patients had a history of fracture.18% of our patients were osteoporotic and 43% of them were osteopenic. Femoral BMD was significantly lower among MS patients than age matched controls (P < 0.001, but lumbar BMD showed no difference. There was no correlation between administration of GCs pulses, interferon and BMD; however, we found a significant correlation between EDSS score, quality of life (QoL, disease duration and BMD of both site.Conclusion: As a result of this study, bone loss inevitably occurs in MS patients. The major factor of BMD loss is immobility. Osteoporosis should be managed as part of MS patients

  8. Interaction Between Optical and Neural Factors Affecting Visual Performance

    The human eye suffers from higher order aberrations, in addition to conventional spherical and cylindrical refractive errors. Advanced optical techniques have been devised to correct them in order to achieve superior retinal image quality. However, vision is not completely defined by the optical quality of the eye, but also depends on how the image quality is processed by the neural system. In particular, how neural processing is affected by the past visual experience with optical blur has remained largely unexplored. The objective of this thesis was to investigate the interaction of optical and neural factors affecting vision. To achieve this goal, pathological keratoconic eyes were chosen as the ideal population to study since they are severely afflicted by degraded retinal image quality due to higher order aberrations and their neural system has been exposed to that habitually for a long period of time. Firstly, we have developed advanced customized ophthalmic lenses for correcting the higher order aberration of keratoconic eyes and demonstrated their feasibility in providing substantial visual benefit over conventional corrective methodologies. However, the achieved visual benefit was significantly smaller than that predicted optically. To better understand this, the second goal of the thesis was set to investigate if the neural system optimizes its underlying mechanisms in response to the long-term visual experience with large magnitudes of higher order aberrations. This study was facilitated by a large-stroke adaptive optics vision simulator, enabling us to access the neural factors in the visual system by manipulating the limit imposed by the optics of the eye. Using this instrument, we have performed a series of experiments to establish that habitual exposure to optical blur leads to an alteration in neural processing thereby alleviating the visual impact of degraded retinal image quality, referred to as neural compensation. However, it was also found that

    Although in Crohn's disease post-operative recurrence is common, the determinants of disease recurrence remain speculative. The aim of this study was to examine factors affecting post-operative recurrence of Crohn's disease. A Medline-based literature review was carried out. The following factors were investigated: age at onset of disease, sex, family history of Crohn's disease,smoking, duration of Crohn's disease before surgery,prophylactic medical treatment (corticosteroids, 5-amino salicylic acid [5-ASA] and immunosuppressants),anatomical site of involvement, indication for surgery (perforating or non-perforating disease), length of resected bowel, anast-omotic technique, presence of granuloma in the specimen, involvement of disease at the resection margin, blood transfusions and postoperative complications. Smoking significantly increases the risk of recurrence (risk is approximately twice as high), especially in women and heavy smokers. Quitting smoking reduces the post-operative recurrence rate. A number of studies have shown a higher risk when the duration of the disease before surgery was short. There were, however, different definitions of 'short' among the studies. Prophylactic cortic-osteroids therapy is not effective in reducing the post-operative recurrence. A number of randomized controlled trials offered evidence of the efficacy of 5-ASA (mesalazine) in reducing post-operative recurrence. Recently, the thera-peutic efficacy of immunosuppressive drugs (azathioprine and 6-mercaptopurine) in the prevention of post-operative recurrence has been investigated and several studies have reported that these drugs might help prevent the recurrence. Further clinical trials would be necessary to evaluate the prophylactic efficacy of immunosuppressants.Several studies showed a higher recurrence rate in patients with perforating disease than in those with non-perforating disease. However, evidence for differing recurrence rates in perforating and non

  10. Factors affecting on the particle deposition in the respiratory tract

    International Nuclear Information System (INIS)

    The deposition pattern of inhaled particles in the respiratory tracts is affected by anatomical structure of the respiratory tracts and respiratory pattern of animals, which are modified by many factors as animal species, physiological and psychological conditions, age, sex, smoking drug, lung diseases, etc. In human, studies have been focused on the initial lung deposition of particles and have made it clear that the respiratory pattern, gender, and diseases may have influence on the deposition pattern. On the other hand, there was little knowledge on the initial lung deposition of particles in laboratory animals. Recently, Raabe et al. have reported the initial lung deposition of 169Yb-aluminosilicate particles in mice, rats, hamsters, guinea pigs and rabbits. The authors have also investigated the lung deposition of latex particles with different sizes and 198Au-colloid in rats whose respiratory volumes during the inhalation were monitored by body plethysmography. These experiments indicated that the deposition of inhaled particles in distal lung e.g. small bronchiolar and alveolar region, was much lower in laboratory animals than that of human. This species difference may be due to smaller diameter of respiratory tract and/or shallower breathing and higher respiratory rate of laboratory animals. The experimental animals in which respiratory diseases were induced artificially have been used to investigate the modification factors on the deposition pattern of inhaled particles. As respiratory diseases, emphysema was induced in rats, hamsters, beagle dogs in some laboratories and pulmonary delayed type hypersensitivity reaction in rats was in our laboratory. The initial lung deposition of particles in these animals was consistently decreased in comparison with normals, regardless of the animal species and the type of disease. (author)

    Most studies of children's use of pronouns have focused either on the morphology of personal pronouns or on the anaphoric use of pronouns by older children. The current two studies investigated factors affecting children's choice of pronouns as referring expressions-in contrast with their use of full nouns and null references. In the first study it was found that 2.5- and 3.5-year-old children did not use pronouns differentially whether the adult (a) modeled a pronoun or a noun for the target object or (b) did or did not witness the target event (although there was evidence that they did notice and take account of the adult's witnessing in other ways). In the second study it was found that children of this same age (a) do not use pronouns to avoid unfamiliar or difficult nouns but (b) do use pronouns differently depending on the immediately preceding discourse of the experimenter (whether they were asked a specific question such as "What did X do?" or a general question such as "What happened?"). In the case of specific questions, children prefer to use a null reference but use some pronouns as well (almost never using full nouns); in the case of the generic questions, children use pronouns even more often (and use nouns more as well). This finding was corroborated by some new analyses of children's use of pronouns in specific discourse situations in previously published studies. These findings suggest that children's choice of pronouns as referring expressions in early language development is influenced more by the immediately preceding discourse than other kinds of factors.

  12. Analysis of Factors Affecting Positron Emission Mammography (PEM) Image Formation

    International Nuclear Information System (INIS)

    Image reconstruction for positron emission mammography (PEM) with the breast positioned between two parallel, planar detectors is usually performed by backprojection to image planes. Three important factors affecting PEM image reconstruction by backprojection are investigated: (1) image uniformity (flood) corrections, (2) image sampling (pixel size) and (3) count allocation methods. An analytic expression for uniformity correction is developed that incorporates factors for spatial-dependent detector sensitivity and geometric effects from acceptance angle limits on coincidence events. There is good agreement between experimental floods from a PEM system with a pixellated detector and numerical simulations. The analytic uniformity corrections are successfully applied to image reconstruction of compressed breast phantoms and reduce the necessity for flood scans at different image planes. Experimental and simulated compressed breast phantom studies show that lesion contrast is improved when the image pixel size is half of, rather than equal to, the detector pixel size, though this occurs at the expense of some additional image noise. In PEM reconstruction counts usually are allocated to the pixel in the image plane intersected by the line of response (LOR) between the centers of the detection pixels. An alternate count allocation method is investigated that distributes counts to image pixels in proportion to the area of the tube of response (TOR) connecting the detection pixels that they overlay in the image plane. This TOR method eliminates some image artifacts that occur with the LOR method and increases tumor signal-to-noise ratios at the expense of a slight decrease in tumor contrast. Analysis of image uniformity, image sampling and count allocation methods in PEM image reconstruction points to ways of improving image formation. Further work is required to optimize image reconstruction parameters for particular detection or quantitation tasks

    Background Proprioception plays an important role in knee movements.Since there are controversies surrounding the overall recovery time of proprioception following surgery,it is necessary to define the factors affecting proprioceptive recovery after anterior cruciate ligament (ACL) reconstruction and to investigate the relationship between proprioception and muscle strength.Methods A total of 36 patients who had their ACL reconstructed with a semitendinosus/gracilis graft (reconstructed group:6 months post-surgery) and 13 healthy adults without any knee injury (control group) were included in the study.Knee proprioception was evaluated with a passive reproduction test.Isokinetic strength was measured using the Biodex System.Statistical analysis was used to compare proprioception of the reconstructed group versus the control group,and to define causal factors,including sex,hamstring/quadriceps ratio,and the course of injury before reconstruction.We also investigated the correlation between the passive reproduction error and quadriceps index.Results There was a significant difference in proprioception between the reconstructed and control groups (P <0.05).When the course of injury before reconstruction was less than 4 months,there was a linear correlation with proprioception 6 months after the operation (r=0.713,P <0.05).There was a positive correlation between post-surgery proprioception and the quadriceps index at 6 months post-surgery.Conclusions Impaired knee proprioception is observed 6 months after ACL reconstruction.Within 4 months of injury,early undertaking of reconstruction is associated with better proprioception outcome.Patients with enhanced proprioception have a better quadriceps index.

    Full Text Available For Romania, European Integration came with new challenges for the entire society, especially for investment project promoters, including public higher education institutions. Investments in human capital development and education have an important role in a country’s economic development and growth but, in spite of the large number of human resources development public projects being financed, major problems were identified in their implementation process, particularly factors from the macro-economic and institutional environment. Most of the current interest in this area is centered on identifying and analyzing these key factors since their understanding might lead to ensuring an improvement of the implementation process and to a project’s success. In this context, our paper’s objective is to provide a set of critical success factors for HRD projects’ implementation process by developing a framework for external environment factors’ analysis from a public project management perspective. Taking into consideration the current impact of the external environment’ factors upon projects in Romania, in this paper we chose to focus our attention only on the critical success factors of the external socio-economic, institutional, technological and cultural environment, that affect the implementation phase of a project. We started with an analysis of the Romanian context that allowed us to develop a conceptual framework. We then realized a survey on a sample of three Romanian public universities which implemented projects in human capital development by developing and applying a questionnaire to 112 persons involved as management in projects in order to identify the key factors from the external environment that affect a project’s implementation process. Results show that the most significant factors, with a negative impact, are political and economical ones while technological and cultural factors are

    Wood of Chinese fir and poplar were liquefied in phenol at 150℃ and atmospheric pressure. The liquefied wood were reacted with formaldehyde to synthesize the liquefied wood-based resin. The factors affecting the resinification and the properties of new resin were investigated. The results show that the formaldehyde/liquefied wood molar ratio, reaction temperature, reaction time and sodium hydroxide/liquefied wood molar ratio have important influence on the resin characteristics. With the increase of formaldehyde/liquefied wood molar ratio, the yield of resin increases, and the free phenol content of resins decreases, showing that the resinification of liquefied wood is more complete at higher formaldehyde/liquefied wood molar ratios. The reaction temperature on the viscosity of the liquefied resin has considerable effect; the viscosity of resin increased with increasing reaction temperature,and the amount of liquefied poplar resin increased more quickly than that of liquefied Chinese fir resin. The resinification time also has obvious influence on the viscosity of resin; the viscosity of liquefied poplar resin is more sensitive to resinification time compared with that of liquefied Chinese fir. The amount of sodium hydroxide can improve the water miscibility of liquefied wood resin.The optimum sodium hydroxide/liquefied wood molar ratio for preparation of liquefied wood-based resins exceeds 0.4.

    The aim of this study is to characterize urban spaces, which combine landscape, acoustics, and lighting, and to investigate people's perceptions of urban soundscapes through quantitative and qualitative analyses. A general questionnaire survey and soundwalk were performed to investigate soundscape perception in urban spaces. Non-auditory factors (visual image, day lighting, and olfactory perceptions), as well as acoustic comfort, were selected as the main contexts that affect soundscape perception, and context preferences and overall impressions were evaluated using an 11-point numerical scale. For qualitative analysis, a semantic differential test was performed in the form of a social survey, and subjects were also asked to describe their impressions during a soundwalk. The results showed that urban soundscapes can be characterized by soundmarks, and soundscape perceptions are dominated by acoustic comfort, visual images, and day lighting, whereas reverberance in urban spaces does not yield consistent preference judgments. It is posited that the subjective evaluation of reverberance can be replaced by physical measurements. The categories extracted from the qualitative analysis revealed that spatial impressions such as openness and density emerged as some of the contexts of soundscape perception. PMID:22225033

    Full Text Available The aim of this study was to investigate factors influencing the number of daughters of Holstein bulls during the progeny testing using data provided by the Italian Holstein Friesian Cattle Breeders Association. The hypothesis is that there are no differences among artificial insemination studs (AIS on the daughters distribution among progeny testing bulls. For each bull and beginning from 21 months of age, the distribution of daughters over the progeny testing period was calculated. Data were available on 1973 bulls born between 1986 and 2004, progeny tested in Italy and with at least 4 paternal half-sibs. On average, bulls exited the genetic centre at 11.3±1.1 months and reached their first official genetic proof at 58.0±3.1 months of age. An analysis of variance was performed on the cumulative frequency of daughters at 24, 36, 48, and 60 months. The generalized linear model included the fixed effects of year of birth of the bull (18 levels, artificial insemination stud (4 levels and sire of bull (137 levels. All effects significantly affected the variability of studied traits. Artificial insemination stud was the most important source of variation, followed by year of birth and sire of bull. Significant differences among AI studs exist, probably reflecting different strategies adopted during progeny testing.

    The factors affecting patterns of benthic [seabed] biology and chemistry around 50 Scottish fish farms were investigated using linear mixed-effects models that account for inherent correlations between observations from the same farm. The abundance of benthic macrofauna and sediment concentrations of organic carbon were both influenced by a significant, albeit weak, interaction between farm size, defined as the maximum weight of fish permitted on site at any one time, and current speed. Above a farm size threshold of between 800 and 1000 t, the magnitude of effects at farms located in areas of elevated current speeds were greater than at equivalent farms located in more quiescent waters. Sediment concentrations of total organic matter were influenced by an interaction between distance and depth, indicating that wind-driven resuspension events may help reduce the accumulation of organic waste at farms located in shallow waters. The analyses presented here demonstrate that the production and subsequent fate of organic waste at fish farms is more complex than is often assumed; in isolation, current speed, water depth, and farr size are not necessarily good predictors of benthic impact.

    This study aimed to analyze factors affecting social and family relations of young mothers in the two-year postpartum period. This was a cross-sectional study of 464 young mothers in Teresina, Piauí State, Brazil, who gave birth during the first four months of 2006 in six maternity hospitals. Data were collected from May to December 2008 after identifying the young women in the maternity hospital records. Multivariate analysis used multinomial logistic regression. Married young women (including those in common-law marriages) were 80% less likely to have negative relations with their partners. Participants 20 to 22 years of age related 2.4 times better with their mothers than those 17 to 19 years of age. Young women not attending school showed 97% higher odds of negative changes in relations with friends, and Catholics were 50% less likely to have worse relations with friends following childbirth. Measures are needed to orient individuals living with young mothers (especially their partners and mothers) concerning the importance of support in this phase of life, particularly encouraging them to stay in school.

    Full Text Available Bioadhesion is an interfacial phenomenon in which two materials, at least one of which is biological, are held together by means of interfacial forces. When the associated biological system is mucous, it is called mucoadhesion. This property of certain polymeric systems have got place in the drug delivery research in order to prolong contact time in the various mucosal route of drug administration, as the ability to maintain a delivery system at a particular location for an extended period of time has a great appeal for both local action as well as systemic drug bioavailability. A complete and comprehensive theory that can predict adhesion based on the chemical and/or physical nature of a polymer is not yet available. Several theories have been proposed to explain the fundamental mechanisms of adhesion such as glues, adhesives, and paints, have been adopted to study the mucoadhesion. Mucoadhesion is a complex process and numerous theories have been presented to explain the mechanisms involved. These theories include mechanical-interlocking, electrostatic, diffusion–interpenetration, adsorption and fracture processes. They are Electronic theory, Adsorption theory, Wetting theory, Diffusion theory, Fracture theory. The objective of the study is to explain the different mechanisms involved in mucoadhesion and various factors affecting mucoadhesion.

  5. Statistical factors affecting the success of nuclear operations

    International Nuclear Information System (INIS)

    In this article, the authors present a statistical analysis to determine the operational, financial, technical, and managerial factors that most significantly affect the success of nuclear operations. The study analyzes data for over 70 nuclear plants and 40 operating companies over a period of five years in order to draw conclusions that they hope will be of interest to utility companies and public utility commissions as they seek ways to improve rates of success in nuclear operations. Some of these conclusions will not be surprising--for example, that older plants have heavier maintenance requirements--but others are less intuitive. For instance, the observation that operators of fewer plants have lower costs suggests that any experience curve benefits associated with managing multiple nuclear facilities is overshadowed by the logistic problems of multiple facilities. After presenting a brief history of nuclear power in America, the authors outline the motivations of the study and the methodology of their analysis. They end the article with the results of the study and discuss some of the managerial implications of these findings

    Full Text Available Niger faces many natural and human constraints explaining the erratic evolution of its agricultural production over time. Unfortunately, this is likely to cause a decline in the food supply. This study attempts to identify factors affecting rural households’ resilience to food insecurity in Niger. For this, we first create a resilience index by using principal component analysis and later apply structural equation modeling to identify its determinants. Data from the 2010 National Survey on Households’ Vulnerability to Food Insecurity done by the National Institute of Statistics is used. The study shows that asset and social safety net indicators are significant and have a positive impact on households’ resilience. Climate change approximated by long-term mean rainfall has a negative and significant effect on households’ resilience. Therefore, to strengthen households’ resilience to food insecurity, there is a need to increase assistance to households through social safety nets and to help them gather more resources in order to acquire more assets. Furthermore, early warning of climatic events could alert households, especially farmers, to be prepared and avoid important losses that they experience anytime an uneven climatic event occurs.

    The radius of an exoplanet may be affected by various factors, including irradiation, planet mass and heavy element content. A significant number of transiting exoplanets have now been discovered for which the mass, radius, semi-major axis, host star metallicity and stellar effective temperature are known. We use multivariate regression models to determine the dependence of planetary radius on planetary equilibrium temperature T_eq, planetary mass M_p, stellar metallicity [Fe/H], orbital semi-major axis a, and tidal heating rate H_tidal, for 119 transiting planets in three distinct mass regimes. We determine that heating leads to larger planet radii, as expected, increasing mass leads to increased or decreased radii of low-mass (2.0R_J) planets, respectively (with no mass effect on Jupiter-mass planets), and increased host-star metallicity leads to smaller planetary radii, indicating a relationship between host-star metallicity and planet heavy element content. For Saturn-mass planets, a good fit to the radii...

    BACKGROUND: Stroke can affect a person\\'s ability to drive, an important means of transportation in the developed world. AIMS: To determine percentage of patients and factors associated with return to driving post-stroke in a service with emphasis on driver assessment. METHODS: Retrospective study of patients discharged from the Stroke Service of our 470-bed teaching hospital from 1998 to 2002. RESULTS: Of 72 drivers pre-stroke, 54% recalled a driving assessment and 68% returned to driving. Younger patients (58.6 +\\/- 12.0 vs. 66.5 +\\/- 10.5, p = 0.008) with lower Modified Rankin Score (median 1 vs. 2, p = 0.0001) and normal cognition (55 vs. 43%, p = 0.45) were more likely to resume driving. More patients who were assessed returned to driving than those who were not (74 vs. 61%, p = 0.31). CONCLUSIONS: A relatively high level of return to driving can be achieved post-stroke with a pro-active approach to driver assessment and rehabilitation. A structured assessment and referral programme should be offered where appropriate.

  10. Factors affecting the ion beam implantation in silicon

    International Nuclear Information System (INIS)

    The factors affecting the ion beam implantation in silicon have been studied using boron, phosphorus, oxygen, and argon ions having energy range 0.5 ke V-200 ke V. It was found that the range of the ions in silicon increases with the increase of their energy and decreases with the increase of their masses. The ionization process is found to be the main process for causing damage in the silicon matrix whether it is produced by the accelerated ions or by the recoiled silicon atoms. The magnitude of ionization in silicon is found to be inversely proportional to the mass of ions. Ionization produced by ions or recoils shows different contributions to the damage depending on the mass of ions where the ions energy loss to ionization decreases from 70% to 23% as the mass is increased from 11 for boron (B) to 40 for argon (Ar). Its magnitude, as produced by ions, is found to decrease with the increase of their masses. Its value is observed to increase in a complementary way with the mass increase. Ions energy loss to vacancies and phonons is found to be independent of the mass of ions. Their values decrease sharply to a minimum within the energy range 0.5-5ke V and levels off at further energy increase up to 200 Ke V. Recoils energy loss to vacancy and phonon production is found to increase with the increase of mass and energy of the accelerated ions

    1998-01-01

    Structural Ceramic Matrix Composites (CMC) have the potential for application in the hot sections of a variety of advanced propulsion and power systems. It is therefore necessary to have a general understanding of the key properties of CMC and Reinforcing Fibers. This need is complicated by the wide variety of application conditions and structural requirements for which CMC's will be used, and the proprietary concerns of the design engineers. CMC's, to be successful, must display properties which are competitive with the currently used high temperature structural materials: (i.e., Iron and Nickel based superalloys, tough monolithic ceramics, and carbon/carbon composites.) Structural CMC offers several areas of competition: (1) performance, (i.e., strength and strength retention, creep resistance, and thermal conductivity), (2) reliability (i.e., environmental durability, and damage tolerance) and (3) processing (i.e., capability for varying sizes and shapes, and cost effective fabrication). The presentation further discusses, and illustrates with fiber and CMC data the key fiber properties and processes which strongly affect each CMC area of competition. The presentation further discusses the current knowledge of the important factors which control the key fiber properties. A design guidelines for the optimum fiber characteristics is developed, and the currently available fibers are compared against those guidelines.

  12. Investigating factors affecting the efficiency of gas turbine power cycle

    2014-05-01

    Full Text Available Today, the use of gas turbines in power generation cycles has been growing. Small size, easy installation, high power-to-mass ratio and the ability to load and unload the cycle quickly are the advantages of such systems. Low efficiency is considered as one of the major disadvantages of such power plants. Thus providing a way to increase cycle efficiency can be very effective in making the cycle more efficient and thus saving fuel consumed in such systems. In this paper the thermal efficiency of the cycle is introduced through describing the mechanism of gas turbine in power generation cycle. Then we will examine the factors affecting the efficiency of the cycle and finally practical solutions such as increasing the inlet temperature, recovery, internal cooling of the compressor and heat recovery for increasing efficiency will be explained. Evaluating the polytropic efficiency of cycles shows that increasing the inlet gas temperature has little effect on turbine efficiency and is limited at high levels of ηpoly. Water or steam injection into the gas turbines will not only lead to increased efficiency of the cycle, but also increases the flexibility of the turbine, too.

    The aim of this study descriptive study was to evaluate concordance with medication and those factors that affect the use of medicine in patients with hypertension. Data were collected using a questionnaire completed by 750 patients with hypertension between December 25, 2003, and April 30, 2004, in an outpatient hypertension clinic in Erzincan, Turkey. It was found that 57.9% of the patients did not use their medicines as prescribed. Forgetfulness, aloneness, and negligence were ranked as the top three reasons for this non-concordance, accounting for almost half (49.3%) of all patients with hypertension studied; price (expensive medicines) accounted for another quarter (26.5%). A statistically significant relationship with non-concordance was found for age, education level and profession. Patients' lack of knowledge related to the complications of hypertension was also found to have a statistically significant relationship with not taking medicines as prescribed. Gender, location of residence and salary were not found to be statistically related to concordance. These results indicate the need to educate patients with hypertension on how to use their medicine regularly and indicate also the target populations for this. PMID:23127428

  15. Critical factors which shaped Iranian cities in History

    International Nuclear Information System (INIS)

    The history of Iranian Cities and its associated urban a paces are long and colourful. the role of urban areas has always been an important one. It is important for the purpose at hand, to examine, albeit in a cursory fashion, some of critical factors which shaped the development of Iranian Cities, including urban spaces. Moreover, I believe that these forces created, in Iran, a variable, rational urban system and that the currency set of problemsin Iranian Cities results from new technological forces interacting with l der, historical forces. Of course, making generalizations about Persian towns is at best, a risky business, The wide range of natural and historical forces which have played across the face of this country have created special conditions in each urban settlement. But, in spite of the fact that each Persian town has a distinct character and ambience, one can easily see that these differences occur within a framework which is remarkably similar in both basic principles and details. Now, however, even greater forces are operating in Iran, as all over the world, to alter towns almost beyond recognition. The internal combustion engine is introducing a new scale of distance to the city; telecommunications are giving the city a new time scale; industrialization is challenging the traditional economic bases of cities. Tine and again, for both the East and West, these new forces have overwhelmed the more modest human scale of old towns. Times and again, planners and administrators have realized very late in the process that the other scales must be preserved as well. Iran is no exception. This article offers some suggestion as to how Iranian planners and administrators might preserve the human scale in Persian towns. It begins with a look at the history of Persian towns in an attempt to define (implicitly) the Persian human scale by describing the rational urban systems and details which developed in Iran over some 5,000 years of urbanisation. Then we

    2010-12-01

    Full Text Available Distributors have extended their brand policy to durable good categories such as household appliances and electronic devices, what has been proved to be worthy, although it has received a lot of criticism. Possibly, the higher familiarity of the consumer with private brands, the favourable change of attitude towards them, the availability of technology and, why not, the actual international economic crisis which affects to the domestic economies can be factors which explain this success. The few researches trying to explain the reasons of acceptance of these brands in durable goods have taken us to analyze whether factors determining the purchase of private brands in typical study categories such as food and cosmetics can be applied to durable goods. Preliminary results indicate that it is not possible.

    2005-01-01

    This paper investigates the nutritional status of a randomly selected cohort of school children and the factors affecting it. This random survey was conducted in the state of Selangor, involving 1,405 primary students (aged 9-10 years from 54 national primary schools). Physical examination was carried out on all the students. Information on the students was also obtained from the parents. Blood samples were taken by using the finger pricking technique. Body mass index (BMI) was used as a measure of physical growth. The students were mainly from urban areas (82.9%). The mean age was 9.71 years and a higher proportion was females (51%). Malays constituted 83.6%, Indians 11.6% and Chinese 4.2% of the study population. The mean weight and height were 32.30 kg and 135.18 cm respectively. The mean BMI was 17.42 kg/m2, with 1.2% of the students underweight, 76.3% normal BMI, 16.3% overweight and 6.3% were obese. Nutritional status was significantly related to blood pressure, history of breast feeding, eating fast food, taking canned/bottled drinks, income and educational level of parents. Significant differences in nutritional status between sexes and locations (rural/urban) were also found. The prevalence of overweight and obese children was of concern. There is thus an urgent need for the School Health Program to periodically monitor the school children's eating habits and physical growth. Appropriate counselling on nutritional intake and physical activities should be given not only to schoolchildren but also to their teachers and parents or caregivers. PMID:16425649

    This study was carried out in order to determine the factors affecting the presence of Enterobius vermicularis in schoolchildren. This investigation was a cross-sectional and analytic study. The dependent variable was the presence of parasites and the independent variables were the characteristics of the children, families, houses, toilets and drinking water. A stool specimen was taken in the morning using the cellophane tape method, and examined the same day by microscopy. Data were evaluated using the Chi square test and logistic regression analysis and p children was 8.6+/-2.0 years. The number of residents in their homes averaged 5.4+/-2.0, the average number of children in the homes was 3.2+/-1.9 and 290 (60.8%) houses were single dwellings. The source for piped water in 404 houses (84.7%) was the city network, and there were modern sanitary facilities (toilets) in 377 (70.6%) houses. Enterobius vermicularis was found in 209 (43.8%) children. According to logistic regression analyses, the rate of Enterobius vermicularis was found to be 3.05 times higher in students from the Sait Guzelcan primary school, if there were more than 6 residents in the home 2.05 times even higher and 2.02 times still higher if there were no sanitary facilities at his/her home. When there was a history of parasites in the family, the risk was significantly decreased. The prevalence of Enterobius vermicularis in schoolchildren was higher in slum areas, in crowded homes and in those that lacked modern sanitary facilities. PMID:17124657

    The aim of the study was to determine the factors affecting a climber's ability to ascend Mont Blanc using a number of variables collected at the Gouter Hut (3,817 m) before and after an attempted ascent on the Mont Blanc summit. Subjects (n=285) were tested at 3,817 m prior to their ascent of Mont Blanc. Maximum height ascended in the last 14 days was recorded. End tidal CO2, arterial oxygen saturation (SaO2), heart rate and respiratory rate were measured using a Capnograph (Nellcor Patrick NPB75). Acute mountain sickness (AMS) was assessed using the Lake Louise scoring system. Summit information is available for 216 subjects. None of the subjects who attained 4,000 m in the previous 14 days failed to reach the summit (P=0.04). Previous recent exposure to an altitude of 4,000 m resulted in faster ascent times to the summit than those who had not been above 3,000 m in the previous 14 days (4.02+/-0.6 vs. 4.46+/-0.8 h, P=0.009), higher SaO2 on arrival at the Gouter Hut on day 1 (88.6+/-5 vs. 86.3+/-6%, P=0.004) and lower AMS scores upon arrival at the Gouter Hut after the attempted ascent to the summit 2.5+/-1.8 versus 4.7+/-2.5 U (P=0.001), respectively. It is concluded that recent exposure to 4,000 m confers an advantage to those who wish to ascend a 4,800 m peak. PMID:16235066

  3. Factors Affecting the Sustainability of Groundwater-Source Cooling

    Ferguson, G. A.; Woodbury, A. D.

    2004-12-01

    The use of groundwater in thermal applications has grown in popularity due to increases in environmental awareness and rising energy costs. While this source of energy is generally seen as beneficial to the environment, changes in subsurface temperatures resulting from thermal development and other factors may make this practice unsustainable. An example of such changes in subsurface temperatures has been observed in Winnipeg, Manitoba, where groundwater is extensively used for cooling applications. Temperatures in a regional aquifer beneath the city were found to be as much as ten degrees Celsius greater than those measured in surrounding rural areas. Numerical modeling indicates increases in temperature of up to 5 degrees Celsius can be attributed to downward heat flow originating in buildings in many cases. Areas where increases in temperature were found to be greater corresponded to areas where water is being injected into the aquifer. This water is being produced in the process of using groundwater for cooling applications, such as air conditioning and industrial cooling, and is being injected back into the aquifer to maintain hydraulic head and reduce the demand on Winnipeg's sewer system. In most cases, the heat introduced by injecting this water is significantly affecting temperatures at the production well of the same system and numerical modeling indicates that this is inevitable with the current method of development. The combination of heat loss from buildings and injection of heated water is largely responsible for a reduction in the efficiency of groundwater as a coolant and may eventually make the use of groundwater in cooling applications unsustainable.

    2001-04-01

    This study sought to identify the relationship between three predictor variables, perceived collaboration with medical staff, autonomy and independent actions and an outcome, the value hospital nurses placed on their work. In total 189 critical care and 366 non-critical care nurses completed a mailed survey. Critical care nurses perceived themselves to have a more collaborative relationship with the medical staff, described performing actions independent of medical orders more frequently and perceived their jobs to have more value than non-critical care nurses. However the latter group perceived themselves to have more autonomy in their work. Within both groups collaboration and autonomy were significantly, but weak to moderately correlated with job valuation. Simply expanding the work hospital nurses do is unlikely to result in nurses valuing their jobs more, however promoting an environment of respect and sharing between the medical and nursing staff and supporting nurses when they act in an autonomous fashion may positively influence nurses' perceptions of their work.

    Full Text Available Facial pain often persists long after any identifiable organic pathology has healed. Moreover, in a subgroup of patients with temporomandibular disorder (TMD, no treatment is effective. Knowledge of factors associated with persistent pain in TMD could help identify personalized treatment approaches. Therefore, we conducted a critical review of the literature for the period from January 2000 to December 2013 to identify factors related to TMD development and persistence. The literature findings showed that chronic TMD is marked by psychological distress (somatization and depression, affective distress, fear of pain, fear of movement, and catastrophizing and characteristics of pain amplification (hyperalgesia and allodynia. Furthermore, these factors seem to interact in TMD development. In addition, our review demonstrates that upregulation of the serotonergic pathway, sleep problems, and gene polymorphisms influence the chronicity of TMD. We conclude that psychological distress and pain amplification contribute to chronic TMD development, and that interactions among these factors complicate pain management. These findings emphasize the importance of multidisciplinary assistance in TMD treatment.

    The examination of which protective measures are the most appropriate to be implemented in order to prevent, protect against, respond to, and recover from attacks on critical infrastructures and key resources typically involves a comparison of the consequences that could occur when the protective measure is implemented to those that could occur when it is not. This report describes a framework for evaluation that provides some additional capabilities for comparing optional protective measures. It illustrates some potentially important time-dependent factors, such as the implementation rate, that affect the relative pros and cons associated with widespread implementation of protective measures. It presents example results from the use of protective measures, such as detectors and pretrained responders, for an illustrative biological incident. Results show that the choice of an alternative measure can depend on whether or not policy and financial support can be maintained for extended periods of time. Choice of a time horizon greatly influences the comparison of alternatives.

    Full Text Available Despite improvement of blood transfusion regimens and iron chelation therapy growth and maturational delay, cardiomyopathy, endocrinopathies and osteoporosis still occur in good number of thalassemic patients. Decreased IGF-1 secretion occurs in the majority of the thalassemic patients particularly those with growth and pubertal delay. Many factors contribute to this decreased synthesis of IGF-I including disturbed growth hormone (GH - insulin-like growth factor - I (IGF-I axis. The possible factors contributing to low IGF-I synthesis in thalassemia and the possible interaction between low IGF-I secretion and the occurrence of these complications is discussed in this mini-review. Improvement of IGF-I secretion in thalassemic patients should be intended to improve linear growth and bone mineral accretion in thalassemic patients. This can be attained through adequate correction of anemia and proper chelation, nutritional supplementation (increasing caloric intake, correction of vitamin D and zinc deficiencies, induction of puberty and correction of hypogonadism at the proper time and treating GH deficiency. This review paper provides a summary of the current state of knowledge regarding IGF-I and factors affecting it in patients with thalassaemia major (TM. Search on PubMed and reference lists of articles with the term ′IGF-I, GH, growth, thalassemia, thyroxine, anemia, vitamin D, and zinc′ was carried out. A hundred and forty-eight articles were found and used in the write up and the data analyzed was included in this report.

    The calculated concentrations of radionuclides in organisms are often obtained by means of bioaccumulation factors (BAF) that describe the internal concentration relative to an external concentration e.g. in the abiotic environments at steady-state conditions. Such factors are often used when modelling the dose to man from radio-nuclides released to the biosphere. Values of bioaccumulation factors vary widely in magnitude among elements, organisms, and environmental conditions which is not always considered. In order to relate the bioaccumulation factors for some radionuclides to environmental conditions as well as to the trophic level of the organism of concern we have compiled an extensive database with bioaccumulation factors (about 5,500 values) together with information on some environmental conditions. The data for nine radionuclides has been extracted and examined. A comparison between the bioaccumulation factors found in this study and values given in literature by IAEA and NCRP shows that the ranges presented in this study are generally somewhat higher with the exception of BAF for molybdenum in freshwater fish which is of the same order of magnitude. This is startling and calls for a thorough research. The amount of readily accessible and reliable values of BAF is limited, often because basic information such as e.g. units and part of organism examined, is not reported. This is surprising and also unfortunate for those who need such data for use in generic or specific models. A major update of recommended values appears to be necessary for many elements to account for the development of analytical methods and experiences from case studies over the past two decades.

    Disproportionate exposure of minority groups to environmental hazards has been attributed to ``environmental racism`` by some authors, without systematic investigation of the factors underlying this exposure pattern. This study examines regional differences in the proximity of African-Americans, Hispanics, Asians, and non-Hispanic Whites to a broad range of facility types and explores the effects of urban and income factors. A statistically significant inverse relationship is found between the percentage of non-Hispanic Whites and virtually all facility categories in all regions. Except for Hispanics in the South, all such associations for minority groups show a direct relationship, though some are nonsignificant. The geographic concentration of facilities is more closely tied to urbanization than to economic factors. Controlling for both urban and economic factors, minority population concentration is still a significant explanatory variable for some facility types in some regions. This finding is most consistent for African-Americans.

    Full Text Available Parents of disabled children often face the question whether or not to keep the child at home or to place them. The choice between the two alternatives resides with the parents and various factors influence their decision. Several researchers have identified these factors, which include child-related parameters, family and parental attitudes, the influence of the social environment, and the external assistance provided to the family. In a pilot study, we attempted to isolate the main factors involved in the parental decision either to keep the child at home or place the child by examining a sample comprised of 50 parents of children suffering severe intellectual disability studying in a special education school and 48 parents of adults with intellectual disability working in sheltered workshops. Each parent filled out a questionnaire used in a study in the United States and results of the research indicated parental-related factors as the dominant factors that delayed the placement of their child in residential care; guilt feelings were the main factor.

    and runners are interested on learning about the factors that affect long-distance running performance. Facing this new reality, scientific literature has been concerned about the aforementioned factors, and the amount of studies has considerably grown. Therefore, the purpose of this review is to analyse factors affecting long-distance running performance from different points of view. Literature review was performed through 3 different databases (Medline, SportDiscus and Google Scholar and the factors were classified into 5 main groups, subdivided into different sections: 1- environmental (air/wind, temperature, humidity, altitude and slope of the ground, 2- training-related (endurance, resistance, training in hot environments and in altitude, 3- physiological (VO2max, thersholds, running economy, age, gender, muscle fibre type, fatigue and race, 4- biomechanical (anthropometry, leg-stiffness, flexibility, foot strike pattern, footwear, foot orthoses and spatio-temporal parameters and 5- psychological (intervention strategies, direction of attention and music. Even though the influence of some of these factors on running performance in quite well-known, the influence of some psychological (direction of attention and music and biomechanical factors (foot strike pattern and spatio-temporal parameters is still unclear. There are few studies or the results cannot be generalized. Future studies and the progress of new technologies and measurement tools will provide a better understanding.

    Scientific evidence suggests that stem cells possessthe anti-aging ability to self-renew and maintaindifferentiation potentials, and quiescent state. Theobjective of this review is to discuss the microenvironmentwhere stem cells reside in vivo , thesecreted factors to which stem cells are exposed, thehypoxic environment, and intracellular factors includinggenome stability, mitochondria integrity, epigeneticregulators, calorie restrictions, nutrients, and vitaminD. Secreted tumor growth factor-β and fibroblastgrowth factor-2 are reported to play a role in stem cellquiescence. Extracellular matrices may interact withcaveolin-1, the lipid raft on cell membrane to regulatequiescence. N-cadherin, the adhesive protein on nichecells provides support for stem cells. The hypoxicmicro-environment turns on hypoxia-inducible factor-1to prevent mesenchymal stem cells aging throughp16 and p21 down-regulation. Mitochondria expressglucosephosphate isomerase to undergo glycolysisand prevent cellular aging. Epigenetic regulators suchas p300, protein inhibitors of activated Stats and H19help maintain stem cell quiescence. In addition, calorierestriction may lead to secretion of paracrines cyclicADP-ribose by intestinal niche cells, which help maintainintestinal stem cells. In conclusion, it is crucial tounderstand the anti-aging phenomena of stem cells atthe molecular level so that the key to solving the agingmystery may be unlocked.

  1. Spurious thermoluminescence in archaeological ceramics: a study of affecting factors

    International Nuclear Information System (INIS)

    The presence of spurious emission heavily affects thermoluminescence measurements, and attempts were made to identify its causes and to circumvent or eliminate it. Samples showing spurious TL, as well as samples with an excellent thermoluminescent behaviour have been analyzed by means of DTA-TG (Differential Thermal Analysis-Thermogravimetric Analysis) and X-ray diffraction. It has been found that more than one kind of spurious thermoluminescence exists, and that calcium carbonate, magnesium carbonate, organic matter and moisture cannot be considered as a general source of spurious TL. Where spurious emission is present, the magnetic fraction of the sample is heavily affected, while in the low magnetic susceptibility fraction a reduction of such emission is obtained. (author)

  6. An information-based rough set approach to critical engineering factor identification

    2008-09-01

    Full Text Available In order to analyze the main critical engineering factors, an information-based rough set approach that considers conditional information entropy as a measurement of information has been developed. An algorithm for continuous attribute discretization based on conditional information entropy and an algorithm for rule extraction considering the supports of rules are proposed. The initial decision system is established by collecting enough monitoring data. Then, the continuous attributes are discretized, and the condition attributes are reduced. Finally, the rules that indicate the action law of the main factors are extracted and the results are explained. By applying this approach to a crack in an arch gravity dam, it can be concluded that the water level and the temperature are the main factors affecting the crack opening, and there is a negative correlation between the crack opening and the temperature. This conclusion corresponds with the observation that cracks in most concrete dams are influenced mainly by water level and temperature, and the influence of temperature is more evident.

  2. A Content Analysis of Factors Affecting New Product Development Process

    Directory of Open Access Journals (Sweden)

    Eda Atilgan-Inan

    2010-07-01

    Full Text Available The objective of this study is to review the international marketing literature on new product development process and compare the changes in the important factors in the process with the changes in the management approaches. For this purpose, the articles in three international marketing journals were selected and “new product development” and “new product performance” were searched for in the abstracts. After grouping the variables in the process, they were compared with the perspectives of management in the related periods. The results indicated that organizational factors have always been important for new product development process, which is in line with the nature of the innovation process. But the emphasis on internal factors has increased in the 21st century which is congruent with the change in management perspective foregrounding resource based view. The study differs from the similar literature review studies on the point that it deals with the topic from international marketing perspective. Therefore, R&D and other marketing studies are not included in the review and the study proposes the important factors from international firms’ point of view.

  6. Factors affecting the acquisition of plural morphology in Jordanian Arabic.

    Albirini, Abdulkafi

    2015-07-01

    This study investigates the development of plural morphology in Jordanian Arab children, and explores the role of the predictability, transparency, productivity, and frequency of different plural forms in determining the trajectory that children follow in acquiring this complex inflectional system. The study also re-examines the development of the notion of default over several years. Sixty Jordanian children, equally divided among six age groups (three to eight years), completed an oral real-word pluralization task and a nonsense-word pluralization task. The findings indicate that feminine sound plurals are acquired before and extended to the other plural forms. Productivity and frequency seem to shape the acquisition patterns among younger children, but predictability becomes more critical at a later age. Younger children use the most productive plural as the default form, but older children tend to use two default forms based on frequency distributions in the adult language. The theoretical implications of the findings are discussed. PMID:25158792

  7. Two-factor theory, the actor-critic model, and conditioned avoidance.

    Maia, Tiago V

    2010-02-01

    Two-factor theory (Mowrer, 1947, 1951, 1956) remains one of the most influential theories of avoidance, but it is at odds with empirical findings that demonstrate sustained avoidance responding in situations in which the theory predicts that the response should extinguish. This article shows that the well-known actor-critic model seamlessly addresses the problems with two-factor theory, while simultaneously being consistent with the core ideas that underlie that theory. More specifically, the article shows that (1) the actor-critic model bears striking similarities to two-factor theory and explains all of the empirical phenomena that two-factor theory explains, in much the same way, and (2) there are subtle but important differences between the actor-critic model and two-factor theory, which result in the actor-critic model predicting the persistence of avoidance responses that is found empirically.

    This paper examines the use of non subject related tags in social bookmarking tools. Previous studies of tagging determined that many common tags are not directly subject related but are in fact affective tags dwelling on a user's emotional response to a document or are time and task related tags related to a users current projects or activities. These tags have been analysed to examine their role in the tagging process. (Paper at http://www.cais-acsi.ca/proceedings/2008/kipp_2008.pdf)

  12. Comparing critical success factors for PV between three regions

    International Nuclear Information System (INIS)

    As a research method the project team has chosen to survey the opinion of PV experts and persons involved in the implementation of PV. Therefore, a questionnaire was sent to about 300 persons spread among 3 regions America, Europe and Asia. The returned questionnaires have been statistical analysed with the software tool SPSS. The used analytical methods can be divided in a comparing method (Mann-Whitney test) and ranking methods (Friedman test and the medal classification test). General conclusions are that there is a significant difference in answers between America and Europe about the significance of 'cost reduction'. Also Asia is significant different from America and Europe for the factor 'technical' reliability. There is a significant difference about the status of financing between America and Europe versus Asia. All the regions have a different opinion about the status of RD and D'. Also the status of 'the PV network' is significant different between Asia and America. America and Europe rank 'financial aspects' and 'cost reduction' as the most significant aspects while Asia rank 'specialist knowledge' and 'the PV network' as the most significant. All regions rank 'specialist knowledge' having the worst status and rank 'environmental merits' and 'technical reliability' having the best status. Finally Europe and Asia differ significant about which aspect is the most important for the factors 'internationalisation and other activities'. Europe finds 'harmonisation of policy' the most important internationalisation aspect and Asia prefers 'development aid'. Asia prefers 'pioneering activities' and Europe prefers 'initiatives by social organisations' as most important other activity. (au)

    2003-01-01

    Full Text Available Milk quality is determined by chemical composition, physical characteristics and hygienic parameters. The main indicators of hygienic quality of milk are total number of microorganisms and somatic cell count (SCC. Environmental factors have the greatest influence on increasing SCC. The most important environmental parameters are status of udder infection, age of cow, stage of lactation, number of lactation, breed, housing, geographicalarea and seasons, herd size, stress, heavy physical activity and, milking. A farmer (milk producer himself can control a great number of environmental factors using good management practise and permanent education. Since SCC participate in creating the price of milk, it is necessary to inform milk producers how to organise their production so that they would produce maximum quantity of good hygienic quality milk.

    Full Text Available The purpose of this research is to identify and examine the factors that contribute to bank switching intentions of e-banking customers and whether these intentions differ according to demographic characteristics (age, gender, education, marital status and income levels of customers. Regression results suggested that customer dissatisfaction, low service quality, high price, unfavorable bank reputation, limited product variety and involuntary switching factors were positively related to customers’ bank switching intentions in e-banking. On the other hand, promotion efforts were negatively related to customers’ switching intentions. In addition to this, bank switching intentions were revealed to be differing according to education levels. Bank switching intentions of well-educated customers were tend to be higher, while age, gender, marital status and income level didn’t make a difference on intentions. Based on the empirical results of current study, we will provide several theoretical and managerial implications in the area of service industry.

  17. Factors affecting visualization of posterior rib fractures in abused infants

    International Nuclear Information System (INIS)

    Rib fractures in abused infants commonly occur in the posterior rib arcs. Fractures occurring near the costovertebral articulations are usually identified radiographically only once callus has formed. To assess the factors influencing the visibility of fractures near the costovertical articulations, the authors studied 103 posterior rib fractures occurring in 16 abused infants. Radiologic findings were correlated with CT findings and pathologic material from nine ribs in four patients. The limited visibility of fractures relates to (1) the frequent superimposition of the transverse process over the rib fracture site, (2) a fracture line that crosses at an obliquity to the x-ray beam, and (3) nondisplacement of rib fragments due to preservation of the posterior periosteum. Fresh rib fractures invisible on a frontal projection may be clearly defined on axial CT scans, or on postmortem radiographs. A knowledge of the factors influencing the visibility of these important injuries is useful in planning an appropriate diagnostic evaluation of suspected infant abuse

    2014-02-01

    Full Text Available Somatic cell count (SCC in monitoring udder health has been described in numerous studies as a useful method for the diagnosis of intramammary infection (IMI, and it is considered in standards of quality and hygiene of cow’s milk in many countries. However, several authors have questioned the validity of SCC as a reliable IMI diagnosis tool in dairy goats. This review attempts to reflect the importance of different infectious and non-infectious factors that can modify SCC values in goat milk, and must, therefore, be taken into account when using the SCC as a tool in the improvement of udder health and the quality of milk in this species. In dairy goats, some investigations have shown that mammary bacterial infections are a major cause of increased SCC and loss of production. In goats however, the relationship between bacterial infections and SCC values is not as simple as in dairy cattle, since non-infectious factors also have a big impact on SCC. Intrinsic factors are those that depend directly on the animal: time and number of lactation (higher SCC late in lactation and in aged goats, prolificity (higher SCC in multiple births, milking time (higher SCC in evening compared to morning milking and number of milkings per day, among others. Extrinsic factors include: milking routine (lower SCC in machine than in manual milking, seasonality and food. In addition, milk secretion in goats is mostly apocrine and therefore characterized by the presence of epithelial debris or cytoplasmic particles, which makes the use of DNA specific counters mandatory. All this information is of interest in order to correctly interpret the SCC in goat milk and to establish differential SCC standards.

  7. Review of factors affecting sustainability in the universities

    Science.gov (United States)

    Ajilian, Hosna

    Understanding the factors which influence adopting sustainability practices in IHE is an important issue to develop more effective sustainability's methods and policies. The focus of this research is to find out a meaningful relationship between adopting sustainability practices and some of the characteristics of institutions of higher education (IHE). IHE can be considered as the best place to promote sustainability and develop the culture of sustainability in society. Thus, this research is conducted to help developing sustainability in IHE which have significant direct and indirect impact on society and the environment. First, the sustainability letter grades were derived from "Greenreportcard.org" which have been produced based on an evaluation of each school in nine main categories including: Administration, Climate Change & Energy, Food & Recycling, etc. In the next step, the characteristics of IHE as explanatory variables were chosen from "The Integrated Postsecondary Education Data System" (IPEDS) and respective database was implemented in STATA Software. Finally, the "ordered-Probit Model" is used through STATA to analyze the impact of some IHE's factor on adopting sustainability practices on campus. The results of this analysis indicate that variables related to "Financial support" category are the most influential factors in determining the sustainability status of the university. "The university features" with two significant variables for "Selectivity" and "Top 50 LA" can be classified as the second influential category in this table, although the "Student influence" is also eligible to be ranked as the second important factor. Finally, the "Location feature" of university was determined with the least influential impact on the sustainability of campuses.

    Biotic and abiotic factors influence the accumulation of organic carbon (Corg) in seagrass ecosystems. We surveyed Posidonia sinuosa meadows growing in different water depths to assess the variability in the sources, stocks and accumulation rates of Corg. We show that over the last 500 years, P. sinuosa meadows closer to the upper limit of distribution (at 2-4 m depth) accumulated 3- to 4-fold higher Corg stocks (averaging 6.3 kg Corg m-2) at 3- to 4-fold higher rates (12.8 g Corg m-2 yr-1) compared to meadows closer to the deep limits of distribution (at 6-8 m depth; 1.8 kg Corg m-2 and 3.6 g Corg m-2 yr-1). In shallower meadows, Corg stocks were mostly derived from seagrass detritus (88 % in average) compared to meadows closer to the deep limit of distribution (45 % on average). In addition, soil accumulation rates and fine-grained sediment content (factors within the meadow. We conclude that there is a need to improve global estimates of seagrass carbon storage accounting for biogeochemical factors driving variability within habitats.

    Full Text Available Background. This study aims to verify if the presence and severity of perinatal depression are related to any particular pattern of attachment. Methods. The study started with a screening of a sample of 453 women in their third trimester of pregnancy, who were administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS and the Experience in Close Relationship (ECR. A clinical group of subjects with perinatal depression (PND, 89 subjects was selected and compared with a control group (C, regarding psychopathological variables and attachment patterns. Results. The ECR showed a prevalence of “Fearful-Avoidant” attachment style in PND group (29.2% versus 1.1%, p<0.001; additionally, the EPDS average score increases with the increasing of ECR dimensions (Avoidance and Anxiety. Conclusion. The severity of depression increases proportionally to attachment disorganization; therefore, we consider attachment as both an important risk factor as well as a focus for early psychotherapeutic intervention.

    Full Text Available Data warehousing is the leading and most reliable technology used today by companies for planning, forecasting, and management A lot has been done in this field regarding design and development of data warehouses and a lot still needs to be done but one area which needs special attention from research community is data warehouse maintenance. The main reason for a data warehouse failure is poor management. Without proper management desired results are nearly impossible to attain from a data warehouse. Unlike operational system data warehouse need a lot more management and a support team of qualified professionals is needed to take care of the issues that arise after its deployment including data extraction, data loading, network management, training and communication, materialized view and some other related tasks. The subject of my research is to explore the impact of the selected factors, under organizational, Project related and environmental dimensions, on data warehouse applications

    Temperature is the best known variable affecting the distribution of the archaeal glycerol dibiphytanyl glycerol tetraethers (GDGTs) in marine and freshwater systems. Other variables such as pH, ionic strength, or bicarbonate concentration may also affect archaeal GDGTs in terrestrial systems. Studies of pure cultures can help us pinpoint the specific effects these variables may have on archaeal lipid distribution in natural environments. In this study, three Sulfolobus species (HG4, HB5-2, HB9-6) isolated from Tengchong hot springs (pH 2-3, temperature 73-90°C) in China were used to investigate the effects of temperature, pH, substrate, and type of strain on the composition of GDGTs. Results showed that increase in temperature had negative effects on the relative contents of GDGT-0 (no cyclopentyl rings), GDGT-1 (one cyclopentyl ring), GDGT-2 and GDGT-3 but positive effects on GDGT-4, GDGT-4', GDGT-5 and GDGT-5'. Increase in pH, on the other hand, had negative effects on GDGT-0, GDGT-1, GDGT-4', GDGT-5 and GDGT-5', and positive effects on GDGT-3 and GDGT-4. GDGT-2 remained relatively constant with changing pH. When the HG4 was grown on different substrates, GDGT-5 was five time more abundant in sucrose-grown cultures than in yeast extract- or sulfur- grown cultures, suggesting that carbohydrates may stimulate the production of GDGT-5. For all three species, the ring index (average number of rings) of GDGTs correlated positively with incubation temperature. In HG4, ring index was much lower at optimal pH (3.5) than at other pH values. Ring index of HB5-2 or HB9-6 is higher than that of HG4, suggesting that speciation may affect the degree of cyclization of GDGT of the Sulfolobus. These results indicate that individual archaeal lipids respond differently to changes in environmental variables, which may be also species specific.

  3. Evaluation of factors affecting diffusion in compacted bentonite

    International Nuclear Information System (INIS)

    The information available from the open literature and studies on exclusion, sorption and diffusion mechanisms of ionic and neutral species in bentonite has been compiled and re-examined in relation to the microstructure of bentonite. The emphasis is placed on a more thorough understanding of the diffusion processes taking place in compacted bentonite. Despite the scarcity of experiments performed with neutral diffusants, these imply that virtually all the pores in compacted bentonite are accessible to neutral species. Anion exclusion, induced by the overlap of electrical double layers, may render the accessible porosity for anions considerably less than the porosity obtained from the water content of the clay. On the basis of the compiled data, it is highly probable that surface diffusion plays a significant role in the transport of cations in bentonite clays. Moreover, easily soluble compounds in bentonite can affect the ionic strength of porewater and, consequently, exclusion, equilibrium between cations, and surface diffusion

    , solubility followed the order expected from the Hofmeister series, however, a more complex behaviour was seen for the cations. With the exception of lithium, their efficiency to influence the solubility was reversed to what was expected. The polydispersity of the solution was reduced by salt addition and...... zeta potential measurements indicated a shift in pI caused by lithium. Possible explanations for the observations are discussed, extending our present understanding of how salts affect the solubility of proteins, one that to date is primarily based on experiments with lysozyme.

    Behavioral experiments were performed on 342 subjects to determine whether behavior, which could affect the level of personal exposure, is exhibited in response to odors and labels which are commonly used for household chemicals. Potential for exposure was assessed by having subjects perform cleaning tasks presented as a product preference test, and noting the amount of cleaning product used, the time taken to complete the cleaning task, the product preference, and the exhibition of avoidance behavior. Product odor was found to affect product preference in the study with the pleasant odored product being preferred to the neutral and unpleasant products. Product odor was also found to influence the amount of product used; less of the odored products was used compared to the neutral product. The experiment also found that very few of the subjects in the study read the product labels, precluding analysis of the effect of such labels on product use. A postexperiment questionnaire on household cleaning product purchasing and use was administered to participants. The results indicate that significant gender differences exist. Women in the sample reported more frequent purchase and use of cleaning products resulting in an estimated potential exposure 40% greater than for the men in the sample. This finding is somewhat countered by the fact that women more frequently reported exposure avoidance behavior, such as using gloves. Additional significant gender differences were found in the stated importance of product qualities, such as odor and environmental quality. This study suggests the need for further research, in a more realistic use setting, on the impact of public education, labels, and product odor on preference, use, and exposure for different types of consumer products.

    Full Text Available Objective: In this study, we aimed to evaluate the fac­tors that affect the accuracy of estimated fetal weight in ultrasound. Methods: This study was conducted in 3rd degree hospi­tal antenatal outpatient clinic and perinatology inpatient clinic between June 2011 and January 2012. The data were obtained from 165 pregnant women. Inclusion cri­teria were; no additional diseases, giving birth within 48 hours after ultrasound. The same physician executed all ultrasound process. Age, height, weight, obstetric history and obstetric follow –up findings were recorded. Results: Fetal gender, fetal presentation, presence of meconium in amniotic fluid, maternal parity, did not sig­nificantly affect the accuracy of fetal weight estimation by ultrasound. The mean difference between estimated fetal weight and birth weight was 104.48±84 gr in nullipars and 94.2±81 gr in multipars (p=0.44; mean difference was 98.22±79 gr in male babies and 98.15±86 gr in female babies (p=0.99. Mean difference between estimated fetal weight and birth weight was 96.92±81 gr in babies with cephalic presentation and 110.9±90 gr in babies with breech presentation (p=0.53; this difference was 95.36±79 gr in babies with amniotic fluid with meconium and 98.82± 83 gr in babies with amniotic fluid without me­conium (p=0.83. Conclusion: Fetal weight is estimation is one of key points in the obstetrician’s intrapartum managament. And it is important to make fetal weight estimation accurately. In our study, consistent with literature, we observed that fetal gender; meconium presence in amniotic fluid, fetal presentation, maternal parity does not significantly effect the accuracy of fetal weight estimation by ultrasound.

    Full Text Available AIM: This study is proposed to determine the incidence of postpartum depression and the risk factors that may play role in arising of it in Konya because there is not any constructed study previously. METHODS: This cross-sectional study is constructed among 242 mothers in the postpartum period between 2-6 months who applied two village clinics of Meram County, Konya between 1 December 2005- 31 January 2006. Two forms were used to collect necessary data. First form was ‘mother introduction form’ that was prepared by us to determine the sociodemographic properties of mothers, and the second form was Edinburgh Posnatal Depression Scale (EPDS to diagnose the risk of postpartum depression. RESULTS: While the cut-off point of EPDS was taken as 13 and over, the probability of experiencing postpartum depression was detected as 19.4%. The probability of experiencing postpartum depression according to EPDS was high in statistical sense among the mothers who had lower monthly income, psychological problems after the preceding pregnancy, 4 and lower prenatal controls, experienced attitude changes among their husbands and/or husbands’ families after learning gender of baby, and medical problems during these pregnancies. CONCLUSION: The modifiable risk factors are determined as the number of prenatal controls, changing the preconceptions and obsessions related gender of baby of husbands and families via healthy education, and well-qualified prenatal care. The long-term improvable risk factors are detected as improving monthly incomes of the families. [TAF Prev Med Bull 2008; 7(5.000: 391-398

    Alzheimer's disease is considered a progressive brain disease in the older population. Late-onset Alzheimer's disease (LOAD) as a multifactorial dementia has a polygenic inheritance. Age, environment, and lifestyle along with a growing number of genetic factors have been reported as risk factors for LOAD. Our aim was to present results of LOAD association studies that have been done in northwestern Iran, and we also explored possible interactions with apolipoprotein E (APOE) status. We re-evaluated the association of these markers in dominant, recessive, and additive models. In all, 160 LOAD and 163 healthy control subjects of Azeri Turkish ethnicity were studied. The Chi-square test with Yates' correction and Fisher's exact test were used for statistical analysis. A Bonferroni-corrected p value, based on the number of statistical tests, was considered significant. Our results confirmed that chemokine receptor type 2 (CCR2), estrogen receptor 1 (ESR1), toll-like receptor 2 (TLR2), tumor necrosis factor alpha (TNF α), APOE, bridging integrator 1 (BIN1), and phosphatidylinositol-binding clathrin assembly protein (PICALM) are LOAD susceptibility loci in Azeri Turk ancestry populations. Among them, variants of CCR2, ESR1, TNF α, and APOE revealed associations in three different genetic models. After adjusting for APOE, the association (both allelic and genotypic) with CCR2, BIN1, and ESRα (PvuII) was evident only among subjects without the APOE ε4, whereas the association with CCR5, without Bonferroni correction, was significant only among subjects carrying the APOE ε4 allele. This result is an evidence of a synergistic and antagonistic effect of APOE on variant associations with LOAD. PMID:26553058

    The purpose of this study was to assess the factors that influence ART adherence arising in rural settings in Zambia. A survey was conducted with face-to-face interviews using a semi-structured questionnaire and written informed consent was obtained at ART sites in Mumbwa District in rural Zambia. The questionnaire included items such as the socio-demographic characteristics of respondents, support for adherence, ways to remember when to take ARVs at scheduled times, and the current status of adherence. Valid responses were obtained from 518 research participants. The mean age of the respondents was 38.3 years and the average treatment period was 12.5 months. More than half of the respondents (51%) were farmers, about half (49%) did not own a watch, and 10% of them used the position of the sun to remember when to take ARVs. Sixteen percent of respondents experienced fear of stigma resulting from taking ARVs at work or home, and 10% felt pressured to share ARVs with someone. Eighty-eight percent of the participants reported that they had never missed ARVs in the past four days. Multivariable logistic regression analysis identified age (38 years old or less, odds ratio (OR) = 2.5, 95% confidence interval (CI): 1.3-4.8, p=0.005), "remembering when to take ARVs based on the position of the sun" (OR = 3.3, 95% CI: 1.3-8.8, p=0.016), and "feeling pressured to share ARVs with someone" (OR = 4.4, 95% CI: 1.6-12.0, p=0.004) as independent factors for low adherence. As ART services expand to rural areas, program implementers should pay more attention to more specific factors arising in rural settings since they may differ from those in urban settings.

    Canine parvovirus (CPV) is the most important enteric virus infecting canids worldwide. The purpose of this study was to detect CPV in naturally infected dogs from several veterinary clinics distributed throughout Portugal between 2012 and 2014 and to identify risk factors associated with CPV infection. From 209 dogs suspected of being infected with CPV, historical data and clinical signs were collected. Fecal samples were screened for CPV by PCR assay and those positive were confirmed by sequencing. The data was analyzed using logistic regression to investigate associations between each of the predisposing factors and CPV status. Of the samples collected, 77.5% tested CPV-positive. Statistical analysis showed that animals in the three age categories (p<0.001) were at list 12 times more likely to be CPV-positive than older animals. The anthelminthic treatment [OR=0.45, p=0.04] and the rectal temperature (hypothermia, [OR=0.12, p=0.004]) contributed to decrease the likelihood of the dogs be infected with CPV. On the other hand, clinical signs such as depression [OR=4.4, p=0.02] and dehydration status [OR=2.38, p=0.001] made dogs more likely to be CPV-infected. The results indicate that although having a high morbidity, only 18% of the Portuguese dog population died in the study. Some of the risk factors identified in this study have not been commonly reported, yet they are easy to obtain and can be used as prognostic indicators in the veterinary practice. PMID:26294318

    Full Text Available Although the discovery of diamond has propelled Botswana from one of the poorest countries in 1966 to its current economic status as a middle-income country, the country still faces the problems of economic diversification, employment creation, income generation and distribution and poverty alleviation. Governmental and non- Governmental organizations have put many efforts on the development of small and medium Enterprises (SMEs to diversify the economy away from mining, to create jobs, generate income and alleviate poverty. However, the pace of development of SMEs, after 30 years, is very slow. The small business failure rate is currently estimated to be over 80%. There is a general consensus among policy makers, politicians and researchers in Botswana that this trend should not be allowed to continue indefinitely. The purpose of this paper is to investigate the Perceived Critical Success/Failure factors (PCSFs affecting the development of SMEs by collecting primary data from 203 SMEs in 3 cities in the republic of Botswana through a questionnaire. Both descriptive and inferential statistics were employed to present the empirical data. The findings showed that ten PCSFs (human resources development; organizational development, managerial background; managerial leadership and competitive strategy affect the performance of SMEs. The PCSFs are strongly related among themselves, indicating the need for a holistic and systematic approach in addressing them. Important relationships were also found between the PCSFs and firm-specific demographic variables such as ownership status, experience and operation period. Recommendations and implications for the policy and research are also forwarded.

  14. Factors affecting the viability of thermoluminescence dating of glass

    International Nuclear Information System (INIS)

    The aim of this study is to achieve a better understanding of some of the factors that limit the thermoluminescence (TL) dating of glass. Using a 'model system' (lithium-disilicate samples having different levels of crystallinity from 0 to 100%), we show, first, that the TL of glass is reproducible only if the glass is not heated above its temperature glass transition and, second, that there is a clear connection between the TL sensitivity and the degree of crystallinity of the sample. We conclude that thermoluminescence is not a general dating method for archaeological glass, but it can be applied to particular glass samples that have specified characteristics. (author)

    1991-02-01

    Although many dental hygienists have considered pursuing a baccalaureate degree, many barriers intervene to prevent accomplishment of this goal. The external degree is one option that could be available to overcome some of the barriers to accessibility. An external program is one that makes education accessible to students in nontraditional ways. A characteristic of these programs is that students can usually pursue academic credit toward a degree without being physically present on the degree-granting campus for the majority of the program. This paper reports the results of a 1988 survey of certificate and associate degree dental hygienists' interest in an external baccalaureate degree completion program. A questionnaire was mailed to 213 certificate and associate degree dental hygienists in Tennessee who had expressed an interest in degree completion. Two hundred six questionnaires were returned for a response rate of 96.7%. In order to determine the potential success of such programs, the following factors were explored: the motivations or reasons for participating; program design factors that might encourage or deter participation; degree of employer support; and individual characteristics relevant to participation, such as personal commitment and demographic information. Geographic location, flexibility in scheduling, and accessibility to course work were the program design factors most important to the likely participants. Likely participants indicated that they wanted to return to complete their baccalaureate degrees for personal satisfaction, for the status of the degree, and to increase their knowledge and skill in dental hygiene. They indicated that they did not want to change the focus of their careers. The area of study rated as most important was advanced clinical dental hygiene. The likely participants were found to resemble other nontraditional students. They averaged 34 years of age, were married with children living at home, and were able to study
