Full Text Available Unemployment is one of the leading economic problems in a developed world. The aim of this paper is to identify the differences in unemployment duration in different strata in the post-crisis Czech Republic via building a minimal adequate model, and to quantify the differences. Data from Labour Force Surveys are used and since they are interval censored in nature, proper metodology must be used. The minimal adequate model is built through the accelerated failure time modelling, maximum likelihood estimates and likelihood ratio tests. Variables at the beginning are sex, marital status, age, education, municipality size and number of persons in a household, containing altogether 29 model parameters. The minimal adequate model contains 5 parameters and differences are found between men and women, the youngest category and the rest and the university educated and the rest. The estimated expected values, variances, medians, modes and 90th percentiles are provided for all subgroups.

Objective To describe the utilization of prenatal care in American Samoan women and to identify socio-demographic predictors of inadequate prenatal care utilization. Methods Using data from prenatal clinic records, women (n=692) were categorized according to the Adequacy of Prenatal Care Utilization Index as having received adequate plus, adequate, intermediate or inadequate prenatal care during their pregnancy. Categorical socio-demographic predictors of the timing of initiation of prenatal care (week of gestation) and the adequacy of received services were identified using one way Analysis of Variance (ANOVA) and independent samples t-tests. Results Between 2001 and 2008 85.4% of women received inadequate prenatal care. Parity (P=0.02), maternal unemployment (P=0.03), and both parents being unemployed (P=0.03) were negatively associated with the timing of prenatal care initation. Giving birth in 2007–2008, after a prenatal care incentive scheme had been introduced in the major hospital, was associated with earlier initiation of prenatal care (20.75 versus 25.12 weeks; Pprenatal care utilization in American Samoa is a major concern. Improving healthcare accessibility will be key in encouraging women to attend prenatal care. The significant improvements in the adequacy of prenatal care seen in 2007–2008 suggest that the prenatal care incentive program implemented in 2006 may be a very positive step toward addressing issues of prenatal care utilization in this population.

Establishing adequate conditions for mercury determination in environmental samples by INAA

International Nuclear Information System (INIS)

Perez, Caroline; Santos, Eliane C.; Saiki, Mitiko

Mercury (Hg) is a toxic element released into the environment mainly by anthropic activities. Consequently, the improvement for Hg determination in environmental samples is of great interest. Instrumental Neutron Activation Analysis (INAA) is considered an adequate method to determine several elements. However, Hg determination by INAA is often hampered by its volatility, which causes losses. The aim of this study was to establish adequate irradiation conditions for Hg determination in environmental samples by INAA. The following parameters were evaluated: irradiation time, container for irradiation and spectral gamma ray interferences. For the study, aliquots of certified reference materials (CRMs) and tree bark samples were irradiated together with Hg synthetic standard at the IEA-R1 nuclear research reactor. Gamma ray activities of 1 97 Hg and 203 Hg were measured in a spectrometer coupled to a HGe detector. Results obtained indicated that polyethylene capsules or envelopes can be used as container for sample irradiation and the Hg impurities in these containers were negligible. Irradiation time of one hour was adequate for Hg determination and in long irradiations of 8 h problems of spectral interference of 198 Au and 75 Se were observed. In addition, Hg loss during the irradiation of 1 h and after irradiation was not observed. Quality control of Hg results, obtained in the CRMs analyses using one hour of irradiation, indicated good precision and accuracy with |Z score| < 2. The experimental conditions established in this study were applied to tree bark samples. Detection limits for Hg of these analyses were between 0.14 and 1.9 μg g -1 . (author)

To evaluate how immediate reconstruction (IR) impacts postmastectomy radiotherapy (PMRT) dose distributions to the reconstructed breast (RB), internal mammary nodes (IMN), heart, and lungs using quantifiable dosimetric end points. 3D conformal plans were developed for 20 IR patients, 10 autologous reconstruction (AR), and 10 expander-implant (EI) reconstruction. For each reconstruction type, 5 right- and 5 left-sided reconstructions were selected. Two plans were created for each patient, 1 with RB coverage alone and 1 with RB + IMN coverage. Left-sided EI plans without IMN coverage had higher heart Dmean than left-sided AR plans (2.97 and 0.84 Gy, p = 0.03). Otherwise, results did not vary by reconstruction type and all remaining metrics were evaluated using a combined AR and EI dataset. RB coverage was adequate regardless of laterality or IMN coverage (Dmean 50.61 Gy, D95 45.76 Gy). When included, IMN Dmean and D95 were 49.57 and 40.96 Gy, respectively. Mean heart doses increased with left-sided treatment plans and IMN inclusion. Right-sided treatment plans and IMN inclusion increased mean lung V{sub 20}. Using standard field arrangements and 3D planning, we observed excellent coverage of the RB and IMN, regardless of laterality or reconstruction type. Our results demonstrate that adequate doses can be delivered to the RB with or without IMN coverage.

Universal use of iodized salt is a simple and inexpensive method to prevent and eliminate iodine deficiency disorders like mental retardation. However, little is known about the level of adequately iodized salt consumption in the study area. Therefore, the study was aimed at assessing the proportion of households having adequately iodized salt and associated factors in Wolaita Sodo town and its peripheries, Southern Ethiopia. A cross-sectional study was conducted from May 10 to 20, 2016, in 441 households in Sodo town and its peripheries. Samples were selected using the systematic sampling technique. An iodometric titration method (AOAC, 2000) was used to analyze the iodine content of the salt samples. Data entry and analysis were done using Epi Info version 3.5.1 and SPSS version 16, respectively. The female to male ratio of the respondents was 219. The mean age of the respondents was 30.2 (±7.3 SD). The proportion of households having adequately iodized salt was 37.7%, with 95% CI of 33.2% to 42.2%. Not exposing salt to sunlight with [OR: 3.75; 95% CI: 2.14, 6.57], higher monthly income [OR: 3.71; 95% CI: 1.97-7.01], and formal education of respondents with [OR: 1.75; 95% CI: 1.14, 2.70] were found associated with the presence of adequately iodized salt at home. This study revealed low levels of households having adequately iodized salt in Wolaita Sodo town and its peripheries. The evidence here shows that there is a need to increase the supply of adequately iodized salt to meet the goal for monitoring progress towards sustainable elimination of IDD.

Efficiency of rate and latency coding with respect to metabolic cost and time.

Science.gov (United States)

Levakova, Marie

2017-11-01

Recent studies on the theoretical performance of latency and rate code in single neurons have revealed that the ultimate accuracy is affected in a nontrivial way by aspects such as the level of spontaneous activity of presynaptic neurons, amount of neuronal noise or the duration of the time window used to determine the firing rate. This study explores how the optimal decoding performance and the corresponding conditions change when the energy expenditure of a neuron in order to spike and maintain the resting membrane potential is accounted for. It is shown that a nonzero amount of spontaneous activity remains essential for both the latency and the rate coding. Moreover, the optimal level of spontaneous activity does not change so much with respect to the intensity of the applied stimulus. Furthermore, the efficiency of the temporal and the rate code converge to an identical finite value if the neuronal activity is observed for an unlimited period of time.

Full Text Available Abstract Background Although evaluation of at least 12 lymph nodes (LNs is recommended as the minimum number of nodes required for accurate staging of colon cancer patients, there is disagreement on what constitutes an adequate identification of such LNs. Methods To evaluate the minimum number of LNs for adequate staging of Stage II and III colon cancer, 490 patients were categorized into groups based on 1-6, 7-11, 12-19, and ≥ 20 LNs collected. Results For patients with Stage II or III disease, examination of 12 LNs was not significantly associated with recurrence or mortality. For Stage II (HR = 0.33; 95% CI, 0.12-0.91, but not for Stage III patients (HR = 1.59; 95% CI, 0.54-4.64, examination of ≥20 LNs was associated with a reduced risk of recurrence within 2 years. However, examination of ≥20 LNs had a 55% (Stage II, HR = 0.45; 95% CI, 0.23-0.87 and a 31% (Stage III, HR = 0.69; 95% CI, 0.38-1.26 decreased risk of mortality, respectively. For each six additional LNs examined from Stage III patients, there was a 19% increased probability of finding a positive LN (parameter estimate = 0.18510, p Conclusions Thus, the 12 LN cut-off point cannot be supported as requisite in determining adequate staging of colon cancer based on current data. However, a minimum of 6 LNs should be examined for adequate staging of Stage II and III colon cancer patients.

Rocuronium can prevent the obturator jerk during transurethral resection of bladder tumors. We investigated the adequate rocuronium dose required for complete block of the thigh adductor muscles, and its correlation with individual responses of the adductor pollicis muscle to rocuronium. Eleven patients scheduled for transurethral resection of bladder tumors under general anesthesia were investigated. After general anesthesia induction, neuromuscular monitoring of the adductor pollicis muscle and ultrasonography-guided stimulation of the obturator nerve was commenced. Rocuronium, 0.15 mg/kg, was repeatedly administered intravenously. The adequate rocuronium dose required for complete block of the thigh muscles, defined as the cumulative dose of rocuronium administered until that time, and its correlation with the first twitch response of the adductor pollicis muscle on train-of-four stimulation after initial rocuronium administration was analyzed. The rocuronium dose found adequate for complete block of the thigh muscles was 0.30 mg/kg in seven patients and 0.45 mg/kg in the remaining four patients, which did not correlate with the first twitch response. At the time of complete block of the thigh muscles, the neuromuscular blockade level of the adductor pollicis muscle varied greatly, although the level was never more profound than a post-tetanic count of 1. Although the response of the adductor pollicis muscle to rocuronium cannot be used to determine the adequate rocuronium dose required for complete block of the thigh muscles, intense blockade, with maintenance of post-tetanic count at ≤ 1 in the adductor pollicis muscle is essential to prevent the obturator jerk. © 2017 The Acta Anaesthesiologica Scandinavica Foundation.

Iron absorption from adequate Filipino meals representing the three major island groups of the Philippines (Luzon, Visayas, and Mindanao) was studied using double isotope extrinsic tag method. Mean iron absorption of the one-day meal for Metro Manila was 6.6 +- 1.26%. Central Visayas, 6.3 +- 1.15% and Southern Mindanao, 6.4 +- 1.19%. Comparison between meals (breakfast, lunch, dinner) for each region as well as one-day meal for the three regions showed no significant differences (P>0.01). Correlation tests done between iron absorption and the following iron enhancers: ascorbic acid, amount of fish, meat or poultry; and inhibitors: phytic acid and tannic acid, did not give significant results. The overall average of 6.4 +- 1.20% may be used as the iron absorption level from an adequate Filipino meal. This value can be considered as one of the bases for arriving at recommended dietary allowances for iron among Filipinos instead of the 10% iron absorption assumed in 1976.

The vitamin A requirements of elderly humans have not been studied. In a cross-sectional study of 60-88-y-old men (n = 31) and women (n = 31) in rural Philippines, we assessed the dietary intakes of elders with adequate (> or = 0.07 micromol/g) or low (value for elders. The mean (+/- SD) vitamin A intakes of the men and women with adequate vitamin A in liver were 135 +/- 86 and 134 +/- 104 microg retinol activity equivalents (RAE)/d, respectively; intakes of the men and women with low vitamin A in liver were 75 +/- 53 and 60 +/- 27 microg RAE/d, respectively. Total-body vitamin A or liver vitamin A but not serum retinol correlated with dietary RAE, preformed vitamin A, beta-carotene, fat, and protein. An estimated acceptable or sufficient dietary vitamin A intake associated with adequate liver vitamin A concentrations in elders is 6.45 microg RAE/kg body wt; for a reference 76-kg man and a 61-kg woman, these values are approximately 500 and 400 microg RAE/d, respectively. The dietary vitamin A intakes of elders with adequate or low liver vitamin A concentrations as estimated by use of the deuterated-retinol-dilution technique are useful for assessing vitamin A requirements.

Arabidopsis: an adequate model for dicot root systems?

Directory of Open Access Journals (Sweden)

Richard W Zobel

2016-02-01

Full Text Available The Arabidopsis root system is frequently considered to have only three classes of root: primary, lateral, and adventitious. Research with other plant species has suggested up to 8 different developmental/functional classes of root for a given plant root system. If Arabidopsis has only three classes of root, it may not be an adequate model for eudicot plant root systems. Recent research, however, can be interpreted to suggest that pre-flowering Arabidopsis does have at least five (5 of these classes of root. This then suggests that Arabidopsis root research can be considered an adequate model for eudicot plant root systems.

Calculation of the Cost of an Adequate Education in Kentucky: A Professional Judgment Approach

Directory of Open Access Journals (Sweden)

2004-02-01

Full Text Available What is an adequate education and how much does it cost? In 1989, Kentucky’s State Supreme Court found the entire system of education unconstitutional-“all of its parts and parcels”. The Court called for all children to have access to an adequate education, one that is uniform and has as its goal the development of seven capacities, including: (i “sufficient oral and written communication skills to enable students to function in a complex and rapidly changing civilization . . . .and (vii sufficient levels of academic or vocational skills to enable public school students to compete favorably with their counterparts in surrounding states, in academics or in the job market”. Now, over a decade later, key questions remain regarding whether these objectives have been fulfilled. This research is designed to calculate the cost of an adequate education by aligning resources to State standards, laws and objectives, using a professional judgment approach. Seven focus groups were convened for this purpose and the scholarly literature was reviewed to provide multiple inputs into study findings. The study produced a per pupil base cost for each of three prototype school districts and an total statewide cost, with the funding gap between existing revenue and the revenue needed for current operations of $1.097 billion per year (2001-02. Additional key resource requirements needed to achieve an adequate education, identified by professional judgment panels, include: (1 extending the school year for students and teachers, (2 adding voluntary half-day preschool for three and four year olds, and (3 raising teacher salaries. This increases the funding gap to $1.23 billion and suggests that significant new funding is required over time if the Commonwealth of Kentucky is to provide an adequate and equitable education of high quality for all children and youth as directed by the State Supreme Court.

Full Text Available To study whether subjects with a molecular genetic diagnosis of familial hypercholesterolemia (FH or familial defective apoB-100 (FDB are being adequately treated.A questionnaire regarding medical history was sent to 2611 subjects who had been provided with a molecular genetic diagnosis of FH or FDB, and a blood sample was obtained for lipid measurements.956 (36.6% of the 2611 subjects participated. The mean age for starting lipid-lowering therapy was 33.4 (±12.1 years. Among those below 18 years of age, only 20.4% were on lipid-lowering drugs, whereas 89.1% of those aged 18 and above were on lipid-lowering drugs. The mean levels of total serum cholesterol and LDL-cholesterol were 5.7 (±1.5 mmol/l and 3.9 (±1.3 mmol/l, respectively. Among those who were on lipid-lowering drugs, 29.0% and 12.2% had levels of LDL cholesterol below 3.0 mmol/l and 2.6 mmol/l, respectively. Only 47.3% of the 956 subjects were considered as being adequately treated largely due to a failure to titrate their drug regimens. From the use of cholesterol-years score, lipid-lowering therapy must start before the age of 20 in order to prevent the subjects from contracting premature coronary heart disease.The majority of FH/FDB subjects are being diagnosed late in life and are not being adequately treated. In order to prevent them from contracting premature coronary heart disease, it is key that levels of LDL cholesterol are normalized from a young age and that sufficient doses of lipid-lowering drugs are being used.

Iodine deficiency disorders are estimated to affect over 1.9 million people worldwide. Iodine deficiency is especially serious for women during pregnancy and lactation because of the negative consequences for both mother and infant. The aim of this cross-sectional study was to determine the median urinary iodine concentration (UIC) as a population-level indicator of iodine status among rural women farmers of reproductive age (18-45 years) in the province of Prey Veng, Cambodia. A total of 450 women provided a spot morning urine sample in 2012. Of those women, 93% (n = 420) were non-pregnant and 7% (n = 30) were pregnant at the time of collection. UIC was quantified using the Sandell-Kolthoff reaction with modifications. The median UIC of non-pregnant (139 μg/L) and pregnant women (157 μg/L) were indicative of adequate iodine status using the WHO/UNICEF/ICCIDD epidemiological criteria for both groups (median UIC between 100-199 and 150-249 μg/L, respectively). We conclude that non-pregnant and pregnant women in rural Prey Veng, Cambodia had adequate iodine status based on single spot morning urine samples collected in 2012. More research is warranted to investigate iodine status among larger and more representative populations of women in Cambodia, especially in light of recent policy changes to the national program for universal salt iodization.

Can Earth Materials BE Adequately Covered in a - or Two-Semester Course?

Science.gov (United States)

Hefferan, K. P.; O'Brien, J.

2007-12-01

Traditional geology programs offer courses in mineralogy, optical mineralogy, igneous petrology, metamorphic petrology, sedimentology and economic geology. At many universities this suite of mineralogy/petrology courses has been supplanted by a one-semester or two-semester Earth Materials course. This interactive poster poses five questions to faculty and students related to the means by which Earth Materials can be delivered: 1) Available online syllabi demonstrate a wide variation in the topics addressed in Earth Materials courses; is there a standard core of key topics that must be covered and in what level of detail? 2) Can a one-semester or two- semester Earth Materials course adequately cover these topics? 3) Excellent textbooks exist in both mineralogy and in petrology; what textbooks, if any, adequately encompass Earth Materials? 4) How has the online environment changed the way in which we use textbooks in the classroom? 5) Given the evolution of geology programs, higher education and the global economy in the past twenty years, what additional changes can be anticipated with respect to delivery and demand of Earth Materials topics?

Modification of Time-dependent Schrodinger Equation in Quantum Mechanics by Adding Derivations of Time's Flow (Relative Time) with Respect of the Both Space and Time Based on the ``Substantial Motion'' Theory of Iranian Philosopher; Mulla Sadra

In Sadra's theory, the relative time for an atom (body) which is varying continuously becomes momentums of its involved fundamental particles (strings), (time's relativity) [Gholibeigian, APS March Meeting 2015, abstract #V1.023]. Einstein's theory of special relativity might be special form of Sadra's theory. ``The nature has two magnitudes and two elongations, the one is gradual being (wavy-like motion) which belongs to the time and dividable to the former and the next times in mind, and the other is jerky-like motion which belongs to the space and dividable to the former and the next places'' [Asfar, Mulla Sadra, (1571/2-1640)]. Sadra separated the nature of time from nature of space. Therefore we can match these two natures on wave-particle duality. It means that the nature of time might be wavy-like and the nature of space might be jerky-like. So, there are two independent variable sources for particle(s)' flow with respect of its two natures such as potential of flow and relative time which vary with respect of both space and time. Consequently we propose two additional parts to Schrodinger's equation: H⌢ Ψ +tp ∇t' = ih/2 π ∂/∂t Ψ +tp∂/∂t t' , where tp is Planck's time and t' is relative time: t' = f (m , v , t) = t +/- Δt , in which t is time, m is mass and vis speed of particle .

The purposes of this study were to (a) explore whether early fractions understanding at 4 th grade is differentially challenging for students with versus without adequate whole-number competence and (b) identify specific whole-number skill associated with difficulty in fractions understanding. Based on initial whole-number competence, 1,108 4 th graders were classified as having (a) adequate whole-number competence ( n = 775), (b) less severe whole-number difficulty ( n = 201), and (c) severe whole-number difficulty ( n = 132). At the end of 4 th grade, they were assessed on fractions understanding and further classified as with versus without difficulty in fractions understanding. Multi-level logistic regression indicated that compared to students with adequate whole-number competence, those with less severe whole-number difficulty were almost 5 times as likely to experience difficulty with fractions understanding whereas those with severe whole-number difficulty were about 32 times as likely to experience difficulty with fractions understanding. Students with severe whole-number difficulty were about 7 times as likely to experience difficulty with fractions understanding compared to those with less severe whole-number difficulty. Among students with adequate whole-number competence, the pretest whole-number skill distinguishing those with versus without difficulty in fractions understanding was basic division facts (i.e., 2-digit dividend ÷ 1-digit divisor) and simple multiplication (i.e., 3-digit × 1-digit without regrouping). The role of whole-number competence in developing initial fractions understanding and implications for instruction are discussed.

HSQC-1,n-ADEQUATE: a new approach to long-range 13C-13C correlation by covariance processing.

Science.gov (United States)

Martin, Gary E; Hilton, Bruce D; Willcott, M Robert; Blinov, Kirill A

Long-range, two-dimensional heteronuclear shift correlation NMR methods play a pivotal role in the assembly of novel molecular structures. The well-established GHMBC method is a high-sensitivity mainstay technique, affording connectivity information via (n)J(CH) coupling pathways. Unfortunately, there is no simple way of determining the value of n and hence no way of differentiating two-bond from three- and occasionally four-bond correlations. Three-bond correlations, however, generally predominate. Recent work has shown that the unsymmetrical indirect covariance or generalized indirect covariance processing of multiplicity edited GHSQC and 1,1-ADEQUATE spectra provides high-sensitivity access to a (13)C-(13) C connectivity map in the form of an HSQC-1,1-ADEQUATE spectrum. Covariance processing of these data allows the 1,1-ADEQUATE connectivity information to be exploited with the inherent sensitivity of the GHSQC spectrum rather than the intrinsically lower sensitivity of the 1,1-ADEQUATE spectrum itself. Data acquisition times and/or sample size can be substantially reduced when covariance processing is to be employed. In an extension of that work, 1,n-ADEQUATE spectra can likewise be subjected to covariance processing to afford high-sensitivity access to the equivalent of (4)J(CH) GHMBC connectivity information. The method is illustrated using strychnine as a model compound. Copyright © 2011 John Wiley & Sons, Ltd.

Respect in forensic psychiatric nurse-patient relationships: a practical compromise.

Science.gov (United States)

Rose, Donald N; Peter, Elizabeth; Gallop, Ruth; Angus, Jan E; Liaschenko, Joan

2011-03-01

The context of forensic psychiatric nursing is distinct from other psychiatric settings as, it involves placement of patients in secure environments with restrictions determined by the courts. Previous literature has identified that nurses morally struggle with respecting patients who have committed heinous offences, which can lead to the patient being depersonalized and dehumanized. Although respect is fundamental to ethical nursing practice, it has not been adequately explored conceptually or empirically. As a result, little knowledge exists that identifies how nurses develop, maintain, and express respect for patients. The purpose of this study is to analyze the concept of respect systematically, from a forensic psychiatric nurse's perspective using the qualitative methodology of focused ethnography. Forensic psychiatric nurses were recruited from two medium secure forensic rehabilitation units. In the first interview, 13 registered nurses (RNs) and two registered practical nurses (RPNs) participated, and although all informants were invited to the second interview, six RNs were lost to follow-up. Despite this loss, saturation was achieved and the data were interpreted through a feminist philosophical lens. Respect was influenced by factors categorized into four themes: (1) emotive-cognitive reactions, (2) nonjudgmental approach, (3) social identity and power, and (4) context. The data from the themes indicate that forensic psychiatric nurses strike a practical compromise, in their understanding and enactment of respect in therapeutic relationships with forensic psychiatric patients. © 2011 International Association of Forensic Nurses.

``The nature has two magnitudes and two elongations, one is gradual being (wavy-like motion) which belongs to the time and dividable to the former and the next times in mind, and the other one is jerky-like motion which belongs to the space and dividable to the former and the next places'' [Asfar, Mulla Sadra, (1571/2-1640)]. These two separated natures of space-time are matched on wave-particle duality. Therefore, the nature of time can be wavy-like and the nature of space can be jerky-like. So, there are two independent variable sources of particle(s)' flow while they are match exactly with each other. These two sources are potential of flow and potential of time (relative time) which vary with respect to both space and time. Here, we propose two additional parts to Schrodinger's equation with respect to relative time: HΨ + ∇t' = EΨ + ∂t' / ∂t , where t is time and t' is relative time: t' = t +/- Δt [Gholibeigian et al., APS March Meeting 2016], which for each atom becomes: tatom = ∑mnucleons + ∑melectrons where m is momentum [Gholibeigian, APS March Meeting 2015, abstract #V1.023]. Using time's relativity in Schrodinger equation will give us more precious results. AmirKabir University of Technology,Tehran, Iran.

Since 2010 CERN has been a member of the Geneva-based association "Le respect, ça change la vie". Four years later and in conjunction with CERN’s celebration of its 60 years of ‘science for peace’, it is time to launch a new respectful workplace awareness campaign under the auspices of the Ombud.   Mutual respect is a basic pillar of peace. At CERN, we pride ourselves on our history, which started when a handful of Europe’s visionary scientists saw the opportunity that an international laboratory for fundamental research would present in bringing nations together. That idea has worked very well and, today, our success can be measured not only in terms of unprecedented scientific achievements but also in terms of training and education, and exemplary collaboration across borders, cultures and an extensive range of differences. In order for history to continue along these positive lines, and coming back to the awareness campai...

To report on coverage and adequacy of health insurance for children with special health care needs (CSHCN) in 2009-2010 and assess changes since 2001. Data were from the National Survey of Children with Special Health Care Needs (NS-CSHCN), a random-digit telephone survey with 40,243 (2009-2010) and 38,866 (2001) completed interviews. Consistency and adequacy of insurance was measured by: 1) coverage status, 2) gaps in coverage, 3) coverage of needed services, 4) reasonableness of uncovered costs, and 5) ability to see needed providers, as reported by parents. Bivariate and multivariable analyses were conducted to assess factors associated with adequate insurance coverage in 2009-2010. Unadjusted and adjusted prevalence estimates were examined to identify changes in the type of insurance coverage and the proportion of CSHCN with adequate coverage by insurance type. The proportion of CSHCN with private coverage decreased from 64.7% to 50.7% between 2001 and 2009-2010, while public coverage increased from 21.7% to 34.7%; the proportion of CSHCN without any insurance declined from 5.2% to 3.5%. The proportion of CSHCN with adequate coverage varied over time and by insurance type: among privately covered CSHCN, the proportion with adequate coverage declined (62.6% to 59.6%), while among publicly covered CSHCN, the proportion with adequate insurance increased (63.0% to 70.7%). Publicly insured CSHCN experienced improvements in each of the 3 adequacy components. There has been a continued shift from private to public coverage, which is more affordable, offers benefits that are more likely to meet CSHCN needs, and allowed CSHCN to see necessary providers.

How adequate policies can push renewables

International Nuclear Information System (INIS)

Goldemberg, J.; Coelho, S.T.; Lucon, Oswaldo

2004-01-01

The growing interest in the establishment of a minimum share of renewable sources in the world energy matrix, after the Johannesburg's World Summit for Sustainable Development (WSSD), has raised the question about the means for such new technologies to compete with the traditional ones. The Brazilian experience in the last 25 years with ethanol as a replacement for gasoline can illustrate this possibility. Moreover, recent policies introduced by the Federal government for a minimum share of new renewable sources - wind, modern biomass and small hydro - in the Brazilian electricity matrix reinforces the country's commitment to utilize adequate policies for achieving sustainable development

Knowledge, attitude and practice of women in Campinas, São Paulo, Brazil with respect to physical exercise in pregnancy: a descriptive study.

Science.gov (United States)

Ribeiro, Carmen P; Milanez, Helaine

2011-11-03

Pregnancy is a good time to develop healthy lifestyle habits including regular exercise and good nutrition. Programs of physical exercise for pregnant women have been recommended; however, there are few references on this subject in the literature. The objective of this study was to evaluate the knowledge, attitude and practice of pregnant women with respect to appropriate physical exercise during pregnancy, and also to investigate why some women do not exercise during pregnancy. A descriptive study was conducted in which 161 women of 18 to 45 years of age were interviewed in the third trimester of pregnancy. These women were receiving prenatal care at National Health Service (SUS) primary healthcare units and had no pathologies for which physical exercise would constitute a risk. The women were selected at an ultrasonography clinic accredited to the SUS in Campinas, São Paulo. A previously elaborated knowledge, attitude and practice (KAP) questionnaire was used to collect data, which were then stored in an Epinfo database. Statistical analysis was conducted using Pearson's chi-square test and Fisher's exact test to evaluate the association between the study variables (p exercise during pregnancy and the vast majority (93.8%) was in favor of it. Nevertheless, only just over 20% of the women in this sample exercised adequately. Significant associations were found between an adequate knowledge of physical exercise during pregnancy and education level (p = 0.0014) and between the adequate practice of physical exercise during pregnancy and having had fewer pregnancies (p = 0.0001). Lack of time and feeling tired and uncomfortable were the principal reasons given by the women for not exercising. These results suggest that women's knowledge concerning the practice of physical exercise during pregnancy is reasonable and their attitude is favorable; however, relatively few actually exercise during pregnancy.

Adequately Addressing Pediatric Obesity: Challenges Faced by Primary Care Providers.

Science.gov (United States)

Shreve, Marilou; Scott, Allison; Vowell Johnson, Kelly

2017-07-01

To assess the challenges primary care providers encounter when providing counseling for pediatric patients identified as obese. A survey assessed the current challenges and barriers to the screening and treatment of pediatric obesity for providers in northwest Arkansas who provide care to families. The survey consisted of 15 Likert scale questions and 4 open-ended questions. Time, resources, comfort, and cultural issues were reported by providers as the biggest barriers in screening and the treatment of pediatric obesity. All providers reported lack of time as a barrier to providing the care needed for obese children. Cultural barriers of both the provider and client were identified as factors, which negatively affect the care and treatment of obese children. Primary care providers continue to experience challenges when addressing pediatric obesity. In this study, a lack of adequate time to address obesity was identified as the most significant current barrier and may likely be tied to physician resources. Although reimbursement for obesity is increasing, the level of reimbursement does not support the time or the resources needed to treat patients. Many providers reported their patients' cultural view of obesity influenced how they counsel their patients. Increasing providers' knowledge concerning differences in how weight is viewed or valued may assist them in the assessment and care of obese pediatric patients. The challenges identified in previous research continue to limit providers when addressing obesity. Although progress has been made regarding knowledge of guidelines, continuing effort is needed to tackle the remaining challenges. This will allow for earlier identification and intervention, resulting in improved outcomes in pediatric obesity.

Current strategies for the restoration of adequate lordosis during lumbar fusion

Science.gov (United States)

Barrey, Cédric; Darnis, Alice

2015-01-01

Not restoring the adequate lumbar lordosis during lumbar fusion surgery may result in mechanical low back pain, sagittal unbalance and adjacent segment degeneration. The objective of this work is to describe the current strategies and concepts for restoration of adequate lordosis during fusion surgery. Theoretical lordosis can be evaluated from the measurement of the pelvic incidence and from the analysis of spatial organization of the lumbar spine with 2/3 of the lordosis given by the L4-S1 segment and 85% by the L3-S1 segment. Technical aspects involve patient positioning on the operating table, release maneuvers, type of instrumentation used (rod, screw-rod connection, interbody cages), surgical sequence and the overall surgical strategy. Spinal osteotomies may be required in case of fixed kyphotic spine. AP combined surgery is particularly efficient in restoring lordosis at L5-S1 level and should be recommended. Finally, not one but several strategies may be used to achieve the need for restoration of adequate lordosis during fusion surgery. PMID:25621216

Junaid, Muhammad; Yang, Kun; Ge, Hanming; Wang, Jianhua

2018-03-01

Unlike sulphur hexafluoride (SF6), liquid nitrogen (LN2) is cost effective, environment friendly and cryogenic dielectric. It has astounding insulating properties with the potential to decrease power loss in switchgear applications due to its remarkably low temperatures. The basic research is however a necessity to observe the performance of LN2 subjected to high luminance arcs. So far, there are no findings that refer to the arcing time inside the LN2 environment. The objective of this work was to investigate the arcing times in LN2 and compare the results with open air conditions using different electrode materials. Experiments were conducted on different DC voltages and their arcing times were measured. Three different kinds of electrode materials, namely: pure copper (Cu), stainless used steel (SUS) and aluminium alloy (Al 6061) were tested under 1 atmospheric pressure. The results revealed that LN2 extinguishes arc in almost half the amount of time required by the open air insulation. With Al 6061 has the shortest arcing time, whilst Cu, the second best choice and SUS places last in the evaluation. It was encapsulated from the findings that LN2 is a better choice than air insulation in terms of arc quenching and a better alternative to SF6 when environment is the priority.

Full Text Available Objectives : As an important element of national security, public health not only functions to provide adequate and timely medical care but also track, monitor, and control disease outbreak. The Nigerian health care had suffered several infectious disease outbreaks year after year. Hence, there is need to tackle the problem. This study aims to review the state of the Nigerian health care system and to provide possible recommendations to the worsening state of health care in the country. To give up-to-date recommendations for the Nigerian health care system, this study also aims at reviewing the dynamics of health care in the United States, Britain, and Europe with regards to methods of medical intelligence/surveillance. Materials and Methods : Databases were searched for relevant literatures using the following keywords: Nigerian health care, Nigerian health care system, and Nigerian primary health care system. Additional keywords used in the search were as follows: United States (OR Europe health care dynamics, Medical Intelligence, Medical Intelligence systems, Public health surveillance systems, Nigerian medical intelligence, Nigerian surveillance systems, and Nigerian health information system. Literatures were searched in scientific databases Pubmed and African Journals OnLine. Internet searches were based on Google and Search Nigeria. Results : Medical intelligence and surveillance represent a very useful component in the health care system and control diseases outbreak, bioattack, etc. There is increasing role of automated-based medical intelligence and surveillance systems, in addition to the traditional manual pattern of document retrieval in advanced medical setting such as those in western and European countries. Conclusion : The Nigerian health care system is poorly developed. No adequate and functional surveillance systems are developed. To achieve success in health care in this modern era, a system well grounded in routine

Do Online Bicycle Routing Portals Adequately Address Prevalent Safety Concerns?

Directory of Open Access Journals (Sweden)

Martin Loidl

2018-03-01

Full Text Available Safety concerns are among the most prevalent deterrents for bicycling. The provision of adequate bicycling infrastructure is considered as one of the most efficient means to increase cycling safety. However, limited public funding does not always allow agencies to implement cycling infrastructure improvements at the desirable level. Thus, bicycle trip planners can at least partly alleviate the lack of adequate infrastructure by recommending optimal routes in terms of safety. The presented study provides a systematic review of 35 bicycle routing applications and analyses to which degree they promote safe bicycling. The results show that most trip planners lack corresponding routing options and therefore do not sufficiently address safety concerns of bicyclists. Based on these findings, we developed recommendations on how to better address bicycling safety in routing portals. We suggest employing current communication technology and analysis to consider safety concerns more explicitly.

Materials and Methods: This prospectively designed multicenter study analyzed 221 breast biopsies at 7 institutions from 04/2006 to 01/2007. Core needle biopsies, vacuum-assisted biopsies and surgical open biopsies under sonographic or mammographic guidance were evaluated. During an analysis of process costs, the individual process steps were recorded in diagrammatic form and assigned to the true consumption of resources. The actual resource consumption costs were entered. A process-related breakeven analysis was conducted to check whether the reimbursement of individual biopsy types covers the costs. Results: Only sonographically guided core needle biopsy and surgical open biopsy are adequately reimbursed in the current German health system. All other breast biopsies indicate a negative profit margin. The principal reasons for underfunding are found in the area of reimbursement of investment and non-personnel costs. Conclusion: The reimbursement of breast biopsies must be improved in order to guarantee nationwide care of the population using the breast biopsy methods recommended in the S 3 guidelines and to avoid disincentives with respect to breast biopsy indications.

Fluoroscopy time - an overestimated factor for patient radiation exposure in invasive cardiology

International Nuclear Information System (INIS)

Kuon, E.; Robinson, D.M.; Empen, K.; Dahm, J.B.

2005-01-01

Purpose: to analyze the effects of an optimized fluoroscopy time on patient radiation exposure in the course of coronary angiography (CA) and percutaneous coronary interventions (PTCA), in comparison to those with consistent collimation to the region of interest (ROI). Furthermore, to analyze efforts concerning reduction of radiographic frames as well as concerning adequate instead of best possible image quality. Material and methods: for 3,115 elective CAs and 1,713 PTCA performed by one interventionist since 1997, we documented the radiographic dose-area products (DAP R ) and fluoroscopic dose-area products (DAP F ), the number of radiographic frames and the fluoroscopy times during selected 2-month intervals. Under conditions of constant image intensifier entrance dose, levels of DAP R /frame and DAP F /s represent valid parameters for consistent collimation. Results: in 1997, the mean baseline values of DAP for elective CA and PTCA amounted to 37.1 and 31.6 Gy x cm 2 , respectively. A reduction of mean fluoroscopy times from 264 to 126 seconds for CA and from 630 to 449 seconds for PCI, both resulted in an overall DAP-reduction of merely 20%. Optimization of mean radiographic frames from 543 to 98 for CA and from 245 to 142 for PTCA enabled reductions of 53 and 13%, respectively. By restriction to adequate instead of best-possible image quality for coronary angiography in clinical routine, we achieved an optimized radiographic DAP/frame of 30.3 to 13.3 mGy x cm 2 , which enabled a 45% reduction of overall DAP. Most efficient however was a consistent collimation to the ROI, which resulted in a remarkable radiation reduction by 46% for CA and by 65% for PTCA. Conclusions: radiation-reducing educational efforts in the clinical routine of invasive cardiology should - against widely held opinion - focus less exclusively toward a reduction of fluoroscopy time but more efficiently toward consistent collimation to the region of interest, reduction of radiographic

[The human right to adequate food: an urban vision].

Science.gov (United States)

Casemiro, Juliana Pereira; Valla, Victor Vincent; Guimarães, Maria Beatriz Lisboa

2010-07-01

The human right to adequate food is comprehended in two dimensions: being free of hunger and denutrition and having access to an adequate food. The urban context, in which the possession of food is done primarily through merchandising because of its strong consuming appealing, became a big challenge to debate this topic in poor districts today. Here we combine considerations of a qualitative study carried out in São João de Meriti, Rio de Janeiro State, joining leaders from Pastoral da Criança in focal group sessions. The unemployment, the sub-employment and the difficulty in reaching the public health system, the social assistance and basic sanitation were presented as the major obstacles to bring into effect the human right to food. It was possible to determine that, among the strategies to fight the poverty and hunger, a big highlight is the establishment of mutual help mechanisms. The social support, generosity and religiousness were presented as the most important categories among the thoughts of the leaders. Facing a reality in which poverty and hunger appear as something inherent or become a mechanism of change during elections, the issue of the clienteles appears as a huge concern and challenge for those leaders.

Improving the suboptimal vegetable consumption among the majority of Australian children is imperative in reducing chronic disease risk. The objective of this research was to determine whether there was a relationship between food security determinants (FSD) (i.e., food availability, access, and utilisation dimensions) and adequate vegetable consumption among children living in regional and remote Western Australia (WA). Caregiver-child dyads ( n = 256) living in non-metropolitan/rural WA completed cross-sectional surveys that included questions on FSD, demographics and usual vegetable intake. A total of 187 dyads were included in analyses, which included descriptive and logistic regression analyses via IBM SPSS (version 23). A total of 13.4% of children in this sample had adequate vegetable intake. FSD that met inclusion criteria ( p ≤ 0.20) for multivariable regression analyses included price; promotion; quality; location of food outlets; variety of vegetable types; financial resources; and transport to outlets. After adjustment for potential demographic confounders, the FSD that predicted adequate vegetable consumption were, variety of vegetable types consumed ( p = 0.007), promotion ( p = 0.017), location of food outlets ( p = 0.027), and price ( p = 0.043). Food retail outlets should ensure that adequate varieties of vegetable types (i.e., fresh, frozen, tinned) are available, vegetable messages should be promoted through food retail outlets and in community settings, towns should include a range of vegetable purchasing options, increase their reliance on a local food supply and increase transport options to enable affordable vegetable purchasing.

2013-01-01

Objectives To investigate the effects of various measures of prenatal care on adverse pregnancy outcomes in women with a history of infertility. Study Design A retrospective cohort study. Methods Data were derived by linking 2 large nationwide population-based datasets, the National Health Insurance Research Database and Taiwan Birth Certificate Registry. The study sample included 15,056 women with an infertility diagnosis and 60,224 randomly selected women without infertility matched to the study sample by maternal age. A conditional logistic regression analysis was performed for the analysis. Results Women diagnosed with infertility respectively had 1.39 (95% CI, 1.06~1.83), 1.15 (95% CI, 1.08~1.24), 1.13 (95% CI, 1.08~1.18), and 1.08 (95% CI, 1.05~1.12) higher odds of having very low birth weight (VLBW) babies, preterm births, labor complications, and cesarean sections (CSs) compared to women without infertility. Inadequate numbers of total and major prenatal visits and late initiation of prenatal care increased the risks of adverse pregnancy outcomes in women with infertility, especially the risk of a VLBW baby. However, no significant associations were found for the risks of adverse birth outcomes in infertile women with adequate prenatal care compared to fertile women with adequate care. Conclusions Study findings suggest that adequate prenatal care can reduce the risk of adverse pregnancy outcomes in women with infertility. PMID:24358347

1989-01-01

The main lesions of the skull and hand, observed in a group of hypertransfused ..beta..-thalassaemic patients, are compared with a control group of low-transfused patients. Bony abnormalities reflect the relationship between proliferating bone marrow and bone cortex, and hypertransfusion therapy will prevent development of lesions only if established early in life. If this is done, the diploe in the skull may become normal, overgrowth of facial bones is moderate, pneumatisation of the paranasal sinuses is not completely prevented, and the 'hair-brush' pattern may disappear completely. A normal appearance of the hand in adequately treated patients differentiates between prepubertal patients and adults.

1980-01-01

Rest and exercise radionuclide ventriculograms were obtained on 77 symptomatic patients without prior documented coronary artery disease (CAD). Coronary artery disease was present by angiograms in 48. Radionuclide ventriculography (RNV) was abnormal in 41 patients (overall sensitivity 85%). In 29 patients with normal coronary arteries, RNV was normal in 24 (specificity 83%). To determine if the exercise level affects sensitivity, the studies were graded for adequacy of exercise. It was considered adequate if patients developed (a) chest pain, or (b) ST segment depression of at least 1 mm, or (c) if they achieved a pressure rate product greater than 250. Among the 48 patients with coronary artery disease, 35 achieved adequate exercise. Thirty-three had an abnormal RNV (sensitivity 94%). In 13 patients who failed to achieve adequate exercise, RNV was abnormal in eight (sensitivity of only 62%). Some patients with coronary artery disease may have a normal ventricular response at inadequate levels of stress

Balanced boron (B) application is well-known to enhance the cotton production; however, the narrow range between B-deficiency and toxicity levels makes it difficult to manage. Cotton genotypes extensively differ in their response to B requirements. The adequate dose of B for one genotype may be insufficient or even toxic to other genotype. The effects of boron (B) on seed cotton yield and its various yield associated traits were studied on 10 cotton genotypes of Pakistan. The pot studies were undertaken to categorize cotton genotypes using B-deficient (control) and B-adequate (2.0 kg B ha-1) levels arranged in CRD with four repeats. The results indicated that the seed cotton yield, yield attributes and B-uptake of genotypes were comparatively decreased in B-deficient stressed treatment. Genotype NIA-Ufaq exhibited wide range of adaptation and ranked as efficient-responsive, as it produced higher seed cotton yield under both B-regimes. SAU-2 and CIM-506 were highly-efficient and remaining all genotypes were medium-efficient. Genotype Sindh-1 produced low seed cotton yield under B deficient condition and ranked as low-efficient. B-efficient cotton genotypes can be grown in B deficient soils without B application. (author)

Nuclear waste disposal: achieving adequate financing - special study

International Nuclear Information System (INIS)

Quasebarth, M.V.

1984-01-01

An analysis by the Congressional Budget Office (CBO) evaluates whether the current one mill fee now charged to nuclear-electricity consumers will adequately finance the waste disposal program. The CBO found that, if the fee is adjusted annually for inflation, it should provide enough revenues to cover all program costs under all nuclear growth forecasts. If the fee is unchanged, however, the fees will be inadequate if inflation exceeds 3% annually. The report suggests two alternatives for fee revision, but makes no recommendations. The alternatives are to increase the fee only at specific intervals or to automatically adjust the fee through indexation. The report examines the effect of delaying the program, cost overruns, and alternative inflation rate and interest rate assumptions. 3 figures, 12 tables

Full Text Available Heart-of-palm, palm heart, or "palmito" can be considered as a non-conventional vegetable, largely consumed in Brazil and exported to more than sixty countries. Timing of heart-of-palm harvesting is a critical issue in palmito agribusiness, since it affects yield, quality and costs. A three-year field experiment was utilized to identify the correct timing for king palm heart-of-palm harvesting, from the standpoint of maximizing yield and minimizing growing period. The experimental site was located at Pariqueraçu, Vale do Ribeira, a region where palmito agribusiness has increased recently, due to adequate climatic conditions, low costs and high industry demand. Crop was grown in 2 x 0.75 m spacing, utilizing six-month old seedlings. Growth was assessed periodically by measuring plant diameter and height (from soil level to insertion of leaf spear, as well as leaf number and size. Harvest was done, from 36 to 40 months after planting date. The results showed high plant variability, a common feature in palm. In spite of genetic variability, the adequate timing for start heart-of-palm harvesting (considering plant growth rate, yield, quality and market type, was reached when palms were 80 to 115 cm (small diameter and 200 to 300 cm tall (large diameter. The time to attain those heights varies widely among plants and growing conditions. In this experiment, harvesting could be started at 22 months after planting.Palmito é uma hortaliça não convencional, largamente consumida no Brasil e exportada para mais de sessenta países. A determinação do tempo adequado para sua colheita é fundamental para o agronegócio palmito, visto que afeta produção, qualidade e custos.

Higgins, P; Murray, M L; Williams, E M

1994-03-01

This descriptive, retrospective study examined levels of self-esteem, social support, and satisfaction with prenatal care in 193 low-risk postpartal women who obtained adequate and inadequate care. The participants were drawn from a regional medical center and university teaching hospital in New Mexico. A demographic questionnaire, the Coopersmith self-esteem inventory, the personal resource questionnaire part 2, and the prenatal care satisfaction inventory were used for data collection. Significant differences were found in the level of education, income, insurance, and ethnicity between women who received adequate prenatal care and those who received inadequate care. Women who were likely to seek either adequate or inadequate prenatal care were those whose total family income was $10,000 to $19,999 per year and high school graduates. Statistically significant differences were found in self-esteem, social support, and satisfaction between the two groups of women. Strategies to enhance self-esteem and social support have to be developed to reach women at risk for receiving inadequate prenatal care.

To examine the impacts on food and nutrition-related outcomes resulting from participation in urban gardens, especially on healthy food practices, healthy food access, and healthy food beliefs, knowledge and attitudes. The systematic review identified studies by searching the PubMed, ERIC, LILACS, Web of Science and Embase databases. An assessment of quality and bias risk of the studies was carried out and a narrative summary was produced. Studies published as original articles in peer-reviewed scientific journals in English, Spanish or Portuguese between 2005 and 2015 were included. The studies included were based on data from adult participants in urban gardens. Twenty-four studies were initially selected based on the eligibility criteria, twelve of which were included. There was important heterogeneity of settings, population and assessment methods. Assessment of quality and bias risk of the studies revealed the need for greater methodological rigour. Most studies investigated community gardens and employed a qualitative approach. The following were reported: greater fruit and vegetable consumption, better access to healthy foods, greater valuing of cooking, harvest sharing with family and friends, enhanced importance of organic production, and valuing of adequate and healthy food. Thematic patterns related to adequate and healthy food associated with participation in urban gardens were identified, revealing a positive impact on practices of adequate and healthy food and mainly on food perceptions.

The postal service is suffering an adaptation to the new markets opened by the users. The traditional post, letters and postcards, is being used less and is substituted by mail and packaging. To adequate to this new market it's important for the postal sector companies. In Spain, the operator of the Universal Postal Service has taken example from other companies of the sector, national and international, implanting electrical bicycle mail and packaging service in the centre of big cities. This is due to the fact that there are more the cities that are forbidding vehicle access to it's historical centres and the volume of packaging to deliver is greater. But, is it viable to deliver using hybrid and electrical vehicles in cities? This study intends to improve the distribution in cities with the implantation of these vehicles. It takes into account the characteristics of populations between 50.000 and 100.000 inhabitants, in which it will be analysed the advantages and inconvenience, doing special emphasis in the economic cost, conducting studies of the costs of implantation and amortization time.

The sensitivity of the Indian summer monsoon to a global warming of 2 C with respect to pre-industrial times

Energy Technology Data Exchange (ETDEWEB)

May, Wilhelm [Danish Meteorological Institute, Danish Climate Centre, Copenhagen (Denmark)

2011-11-15

In this study the potential future changes in different aspects of the Indian summer monsoon associated with a global warming of 2 C with respect to pre-industrial times are assessed, focussing on the role of the different mechanisms leading to these changes. In addition, these changes as well as the underlying mechanisms are compared to the corresponding changes associated with a markedly stronger global warming exceeding 4.5 C, associated with the widely used SRES A1B scenario. The study is based on two sets of four ensemble simulations with the ECHAM5/MPI-OM coupled climate model, each starting from different initial conditions. In one set of simulations (2020-2200), greenhouse gas concentrations and sulphate aerosol load have been prescribed in such a way that the simulated global warming does not exceed 2 C with respect to pre-industrial times. In the other set of simulations (1860-2200), greenhouse gas concentrations and sulphate aerosol load have been prescribed according to observations until 2000 and according to the SRES A1B scenario after 2000. The study reveals marked changes in the Indian summer monsoon associated with a global warming of 2 C with respect to pre-industrial conditions, namely an intensification of the summer monsoon precipitation despite a weakening of the large-scale monsoon circulation. The increase in the monsoon rainfall is related to a variety of different mechanisms, with the intensification of the atmospheric moisture transport into the Indian region as the most important one. The weakening of the large-scale monsoon circulation is mainly caused by changes in the Walker circulation with large-scale divergence (convergence) in the lower (upper) troposphere over the Indian Ocean in response to enhanced convective activity over the Indian Ocean and the central and eastern Pacific and reduced convective activity over the western tropical Pacific. These changes in the Walker circulation induce westerly (easterly) wind anomalies at

This week, I’d like to focus on respect, whether at home, at work or on the international scene. Last week, I had the opportunity to visit the SESAME laboratory in Jordan along with the new European Commissioner for Research, Carlos Moedas.

Adequate Consultation And Dialogue With Local Community Unlocking The Untapped Potential For Peace And Development Evidences From South Omo Zone

Directory of Open Access Journals (Sweden)

Mohammed Yimer

2017-10-01

Full Text Available The paper argues that adequate consultation and public wide dialogues at the grass root level are the two potential entry points in times of development interventions. This will foster peace among the nearby people and led a foundation for the subsequent development. The study was undertaken to examine whether the agro-pastoral communities of South Omo zone were jeopardized as a result of the Omo Kuraz Sugar development project or not. It also targeted whether there was adequate consultation with the local people at the earliest days of the project. Adopting Ethnographic design the study accompanied by primary data collected through participant observation focus group discussion and key informant interview indicated that there were attempts to consult the indigenous people though not adequate. It also indicated that despite the absence of compensation for the local displaced people due to their mobile life the people were not endangered as a result of the project. This project as a development project that is established at the communal land of the agro-pastoralists is providing training for the nearby people to hire them in its various offices. Far from the claims of the various oversees institutions propounded as if the agro-pastoral communities were miserably suffered from such a project the people consider it as if it is their own project. The study implied that South Omo zone is a counter example of how local level consultation and a wide range of dialogue are indispensable preconditions to foster peace and development in many pastoral and agro-pastoral areas of the country.

Respectability, morality and disgust in the night‐time economy: exploring reactions to ‘lap dance’ clubs in England and Wales

Science.gov (United States)

Hubbard, Phil; Colosi, Rachela

2015-01-01

Abstract The night‐time economy is often described as repelling consumers fearful of the ‘undesirable Others’ imagined dominant within such time‐spaces. In this paper we explore this by describing attitudes towards, and reactions to, one particularly contentious site: the ‘lap dance’ club. Often targeted by campaigners in England and Wales as a source of criminality and anti‐sociality, in this paper we shift the focus from fear to disgust, and argue that Sexual Entertainment Venues (SEVs) are opposed on the basis of moral judgments that reflect distinctions of both class and gender. Drawing on documentary analysis, survey results and interview data collected during guided walks, we detail the concerns voiced by those anxious about the presence of lap dance or striptease clubs in their town or city, particularly the notion that they ‘lower the tone’ of particular streets or neighbourhoods. Our conclusion is that the opposition expressed to lap dance clubs is part of an attempt to police the boundaries of respectable masculinities and femininities, marginalizing the producers and consumers of sexual entertainment through ‘speech acts’ which identify such entertainment as unruly, vulgar and uncivilized. These findings are considered in the light of ongoing debates concerning the relations of morality, respectability and disgust. PMID:27708460

Undernutrition among children under 5 years of age in Yemen: Role of adequate childcare provided by adults under conditions of food insecurity.

Science.gov (United States)

Al-Sobaihi, Saber; Nakamura, Keiko; Kizuki, Masashi

2016-01-01

Objective: This study examined the associations between the adequacy of childcare provided by adult caretakers and childhood undernutrition in rural Yemen, independent of household wealth and food consumption. Methods: We analyzed data of 3,549 children under the age of 5 years living in rural areas of Yemen based on the 2013 Yemen Baseline Survey of Mother and Child Health. Nutritional status was evaluated by the presence of underweight, stunting, and wasting according to the World Health Organization child growth standards. The impact of childcare including leaving children alone, putting older children into labor force, and the use of antenatal care while pregnant on child undernutrition was assessed and adjusted for food consumption by children, household composition, demographic and educational background of caretakers, and household wealth. Results: The prevalence of underweight, stunting, and wasting was 46.2%, 62.6%, and 11.1%, respectively. Not leaving children alone, keeping children out of the labor force, and use of antenatal care were associated with a lower risk of underweight (odds ratio [OR] = 0.84, P = 0.016; OR = 0.84, P = 0.036; and OR = 0.85, P = 0.042) and stunting (OR = 0.80, P = 0.004; OR = 0.82, P = 0.024; and OR = 0.78, P = 0.003). After further adjustment for food consumption, the associations between adequate childcare indicators and lower odds of stunting remained significant (OR = 0.73, P = 0.025; OR = 0.72, P = 0.046; and OR = 0.76, P = 0.038). Conclusions: A marked prevalence of stunting among rural children in Yemen was observed. Adequate childcare by adult caretakers in families is associated with a lower incidence of underweight and stunting among children under 5 years of age. Promoting adequate childcare by adult household members is a feasible option for reducing undernutrition among children in rural Yemen.

Edling, D.A.; Griffin, J.F.

1975-01-01

The purpose of this study was to have one ERDA contractor: (1) compile a list of specification packagings, proposed by ERDA contractors, for shipping Type A quantities of radioactive material, and (2) analyze these packages for conformance to Specification 7A requirements. This study was divided into two phases. Phase I provides a report on those packages which could be shown, based on existing test data and engineering analyses, to conform to DOT Specification 7A packaging requirements. The results of Phase I are discussed in detail in the publication, ''Certification of AEC Contractor's Packagings With Respect to Compliance with DOT Specification 7A Performance Requirements -- Phase I Summary Report,'' D. A. Edling, H. E. Meyer and G. L. Phillabaum (Schedule 189C, May 26, 1974). The objectives of Phase II were: (1) identification of packages from Phase I for which available information was not adequate for certification. (Those specification containers used by ERDA contractors and those containers for which adequate information was available for certification are listed in the Phase I summary report.); (2) identification of specific test/engineering analysis data required; (3) generation/procurement of these data; and (4) documentation of study results for use by all ERDA contractors and private industry. The results of Phase II of the study are presented. (U.S.)

Twomey, P.; Neuhoff, K.; Newbery, D.

2006-11-01

This comprehensive final report for the Swiss Federal Office of Energy (SFOE) discusses incentives necessary for the implementation of an adequate, economic and reliable Swiss electricity transmission grid. As Switzerland moves towards a more liberalised and competitive electricity market, an essential task of policy makers will be to ensure that incentives are in place for the construction, maintenance and operation of adequate, economic and reliable transmission infrastructure. As well as continuing to serve the domestic market, the location of Switzerland at the centre of Europe also means that policy should embrace opportunities in servicing the developing European Internal Market by providing transit and other services. Topics discussed include the economic evaluation of transmission investment proposals, regulated transmission investment, investments in transmission lines by power merchants, power auctions and congestion management as well as inter-TSO compensation mechanisms. European regulations and practice are discussed as are access questions and transmission charges. Developments in interconnection management and harmonisation are examined. The particular characteristics of the Swiss energy system, its prices and its legal frameworks are discussed. Cross-border trading and security of supply are also discussed

Respect for rational autonomy.

Science.gov (United States)

Walker, Rebecca L

2009-12-01

The standard notion of autonomy in medical ethics does not require that autonomous choices not be irrational. The paper gives three examples of seemingly irrational patient choices and discusses how a rational autonomy analysis differs from the standard view. It then considers whether a switch to the rational autonomy view would lead to overriding more patient decisions but concludes that this should not be the case. Rather, a determination of whether individual patient decisions are autonomous is much less relevant than usually considered in determining whether health care providers must abide by these decisions. Furthermore, respect for rational autonomy entails strong positive requirements of respect for the autonomy of the person as a rational decision maker. The rationality view of autonomy is conceptually stronger than the standard view, allows for a more nuanced understanding of the practical moral calculus involved in respecting patient autonomy, and promotes positive respect for patient autonomy.

Objective: To evaluate the effect of breast massage at different time in the early period on maternal lactation after cesarean section. Methods: 80 women delivered by cesarean section were randomly selected from maternity ward of a hospital in Shandong province during Jan. 2013 to Jan. 2015; which were divided into four groups, with 20 patients in each. Three groups received 3 times of breast massage every 24 hoursbeginning from 2, 12 and 24 h after cesarean section, respectively. The control group didn't receive any breast massage. The starting time and status of lactation were observed and recorded after cesarean section. 5 ml venous blood sample was drawn from each patient respectively at 2 h before cesarean, 6, 12, 24, 48 and 72 h after cesarean to test the level of serum prolactin. The lactation status of each group was compared. Results: The P (50) ( P (25)- P (75)) of starting time of lactation of the three massage groups and control group were 3 (2-6) h, 4 (2-8) h, 4 (3-12) h and 4 (2-12) h, respectively, whose differences showed no statistical significance ( H =3.32, P= 0.345).The number of delivered women with adequate lactation 24 hours after cesarean was 10 in the group who received massage beginning from 2 h after cesarean; while the number was only 2 in the control group. The number of delivered women with adequate lactation 48 hours after cesarean was 18 in the group who received massage beginning from 2 h after cesarean; while the number was 8 in the control group. The differences showed statistical significances ( P values were 0.021 and 0.008, respectively). The serum prolactin level in the group of delivered women who received massage from 2 h after cesarean was separately (195.9±78.5), (176.0±96.5), (216.4±110.0), (190.0±56.8) and (184.8±69.6) μg/L at 2, 12, 24, 48 and 72 h after cesarean, which were significantly higher than those in the control group (which were (128.8±40.6), (127.3±66.8), (162.2±58.8), (145.1±64.7) and (141.7±49

Ravi Agarwal

2015-02-01

Full Text Available Stability with initial data difference for nonlinear delay differential equations is introduced. This type of stability generalizes the known concept of stability in the literature. It gives us the opportunity to compare the behavior of two nonzero solutions when both initial values and initial intervals are different. Several sufficient conditions for stability and for asymptotic stability with initial time difference are obtained. Lyapunov functions as well as comparison results for scalar ordinary differential equations are employed. Several examples are given to illustrate the theory.

Benign metastasizing leiomyoma: A review of current literature in respect to the time and type of previous gynecological surgery

Barnaś, Edyta; Książek, Mariusz; Raś, Renata; Skręt, Andrzej; Skręt- Magierło, Joanna; Dmoch- Gajzlerska, Ewa

2017-01-01

Introduction Benign metastasizing leiomyoma (BML) is a rare disorder that affects women with a history of uterine leiomyoma, which is found to metastasise within extrauterine sites. The aetiology of BML remains unexplained. Because BML is rare, and most publications contain descriptions of single cases, no statistically determined time relations were found between the primary and secondary surgeries, which may have aetiological implications. Objectives To determine age before BML surgery, age during diagnosis of BML, type of prior surgery, and location of metastasis based on the literature. Methods A systematic review of four databases (Medline/PubMed, Embase, Web of Science, and Cochrane) covering articles published from 1 January 1965 to 10 April 2016. The inclusion criteria were full-text articles in English and articles containing case reports. Articles in languages other than English (39), articles containing incomplete data (14), i.e. no information regarding the time of surgery and/or the site of metastasis, articles bereft of case studies (25), and articles with access only to summaries, without access to the complete text (10) were excluded. Of 321 titles identified, only 126 articles met the aforementioned criteria. Results and conclusions The mean age during primary surgery and BML diagnosis was 38.5 years and 47.3 years, respectively. The most common surgery was total hysterectomy. The most frequent site of metastasis was the lungs; other organs were affected less frequently.The site of metastases and their number were not related to the longer time span between the patient’s initial surgery and occurrence of metastasis. The analysed data, such as the age during primary surgery, age during BML diagnosis, site and type of metastasis, do not provide us a clear answer. Thus, BML pathogenesis is most probably complex in nature and requires further multidirectional research. PMID:28426767

When one is not enough: prevalence and characteristics of homes not adequately protected by smoke alarms.

The National Fire Protection Association (NFPA) has specific recommendations about the number, location, and type of smoke alarms that are needed to provide maximum protection for a household. No previous studies have examined whether or not homes are completely protected according to these guidelines. The authors describe the prevalence and home characteristics associated with compliance to recommendations for smoke alarm installation by the NFPA. Data are from the baseline on-site survey of a randomized trial to measure smoke alarm effectiveness. The trial was housed in a longitudinal cohort study in a rural Iowa county. Of 1005 homes invited, 691 (68.8%) participated. Information about smoke alarm type, placement, and function, as well as home and occupant characteristics, was collected through an on-site household survey. Although 86.0% of homes had at least one smoke alarm, only 22.3% of homes (approximately one in five) were adequately protected according to NFPA guidelines. Fourteen percent of homes had no functioning smoke alarms. More than half of the homes with smoke alarms did not have enough of them or had installed them incorrectly, and 42.4% of homes with alarms had at least one alarm that did not operate. Homes with at least one high school graduate were nearly four times more likely to be fully protected. Homes that had multiple levels, a basement, or were cluttered or poorly cleaned were significantly less likely to be fully protected. These findings indicate that consumers may not be knowledgeable about the number of alarms they need or how to properly install them. Occupants are also not adequately maintaining the alarms that are installed.

Terminology report respect distance. The Use of the term respect distance in Posiva and SKB

International Nuclear Information System (INIS)

Lampinen, H.

2007-09-01

The term respect distance is used in some key publications of the Finnish Nuclear Waste Management Company, Posiva, and the Swedish Nuclear Waste Management Company, SKB (Svensk Kaernbrenslehantering). Posiva and SKB researchers use the same terms in their reports, and it is acknowledged that the terms used by both companies are not used in the same way, though the differences are often subtle. This report is a literature study of the term 'respect distance' and the terms immediately associated to it. Vital terms related to the respect distance and issues concerning the use of scale concepts in Posiva and SKB are gathered in the end of report. Posiva's respect distances consider the seismic, hydrological and mechanical properties of the deterministic deformation zones as important issues that constitute a risk for longterm safety. These requirements for respect distances are an interpretation of STUK's YVL 8.4 Guide. At present, Posiva's criteria regarding respect distances follow the instructions given in the Host Rock Classification system (HRC), whereas the size of a deformation zone to which respect distances are applied vary from the regional to local major and minor. This and other criteria that are given for respect distances may, however, change in the near future as Posiva's Rock Suitability Criteria (RSC) programme proceeds. SKB's considerations of respect distances acknowledge that the hydraulic and mechanical aspects of a deformation zone have an effect on the respect distance. However, the seismic risk is considered to overshadow the other effects on a regional scale. The respect distance defined for a deformation zone is coupled with the size of a fracture where secondary slip could occur. In the safety assessment it is assumed that this fracture cuts a deposition hole location. In SKB the respect distance is determined for regional and local major deformation zones. The trace length of such a zone is defined as being ≥ 3 km. For deformation zones

Tumor response and treatment toxicity are related to minimum and maximum tissue temperatures during hyperthermia, respectively. Using a large set of clinical data, we analyzed the number of sensors required to adequately monitor skin temperature during superficial hyperthermia treatment of breast cancer patients. Hyperthermia treatments monitored with >60 stationary temperature sensors were selected from a database of patients with recurrent breast cancer treated with re-irradiation (23 × 2 Gy) and hyperthermia using single 434 MHz applicators (effective field size 351-396 cm 2 ). Reduced temperature monitoring schemes involved randomly selected subsets of stationary skin sensors, and another subset simulating continuous thermal mapping of the skin. Temperature differences (ΔT) between subsets and complete sets of sensors were evaluated in terms of overall minimum (T min ) and maximum (T max ) temperature, as well as T90 and T10. Eighty patients were included yielding a total of 400 hyperthermia sessions. Median ΔT was 50 sensors were used. Subsets of sensors result in underestimation of T max up to -2.1 °C (ΔT 95%CI), which decreased to -0.5 °C when >50 sensors were used. Thermal profiles (8-21 probes) yielded a median ΔT 50 stationary sensors or thermal profiles. Adequate coverage of the skin temperature distribution during superficial hyperthermia treatment requires the use of >50 stationary sensors per 400 cm 2 applicator. Thermal mapping is a valid alternative.

An assessment of prompt neutron reproduction time in a reflector dominated fast critical system: ELECTRA

Suvdantsetseg, E.; Wallenius, J.

2014-01-01

Highlights: • Prompt neutron reproduction time of ELECTRA is evaluated. • Static and dynamic reproduction times are distinguished for ELECTRA. • Avery-Cohn’s two-region prompt neutron theory is applied. - Abstract: In this paper, an accurate method to evaluate the prompt neutron reproduction time for a reflector dominated fast critical reactor, ELECTRA, is discussed. To adequately handle the problem, explicit time dependent Monte Carlo calculations with MCNP, applying repeated time cut-off technique, are used and compared against the σ∼1/v time dependent absorber method, applying artificial cross-section data in the Monte Carlo code SERPENT. The results show that when a reflector plays a major role in criticality for fast neutron reactor, the two methods predict different physical parameters (Λ=69±2 ns and Λ=83±1 ns for time cut-off and the 1/v method respectively). The reason is explained by applying Avery-Cohn’s two-region prompt neutron model

Toleration out of respect?

DEFF Research Database (Denmark)

Lægaard, Sune

2013-01-01

Under conditions of pluralism different cultures, interests or values can come into conflict, which raises the problem of how to secure peaceful co-existence. The idea of toleration historically emerged as an answer to this problem. Recently Rainer Forst has argued that toleration should not just...... be based on a modus vivendi designed to secure peaceful co-existence, but should be based on moral reasons. Forst therefore advances what he calls the ‘respect conception’ of toleration as an in itself morally desirable type of relationship, which is furthermore the only conception of toleration...... that avoids various so-called ‘paradoxes of toleration’. The paper first examines whether Forst’s respect conception can be applied descriptively to distinguish between actual patterns of behaviour and classify different acts of toleration. Then the focus is shifted to toleration out of respect as a normative...

Search for adequate quality standards for neutron radiography of nuclear fuel

1983-01-01

Unlike in other fields of industrial radiography, where standard methods and procedures are used to control the quality of the radiographic image, no such standard exists for neutron radiography of nuclear fuel. To fill that gap it was felt that standardization work ought to be started in that field, too. Accordingly in 1979 an Euratom Neutron Radiography Working Group was constituted, which initiated standardization work in the field of neutron radiography of nuclear fuel. Finding adequate standards for image quality of neutron radiographs and checking the accuracy of dimension measurements from them were given first priority. (Auth.)

Enhancing entrepreneurship development in Bosnia and Herzegovina through adequate governmental financial support

Full Text Available Entrepreneurship and SME sector is extremely important for general economic development in Bosnia and Herzegovina. In order to enhance further development of the SME sector adequate sources of financing for businesses need to be available and accessible. Entrepreneurs and owners of small and medium businesses in Bosnia and Herzegovina are facing certain challenges in obtaining finances. The issue of accessing sources of finance for SMEs in this country has remained problematic for years. Many relevant studies worldwide emphasise the importance of adequate sources of financing entrepreneurship and SME development. However, a variety of factors influence financing of SMEs depending on the region, economic development, development of financial markets etc. In this paper the authors are addressing the problem of financing SMEs focusing on the governmental support, with emphasis on Bosnia and Herzegovina. The main aim of the paper is to provide an answer to the question whether the government support in Bosnia and Herzegovina enables SMEs to access initial financing, needed for their entrepreneurial activity. The paper presents results of an empirical research conducted among managers of SMEs in Bosnia and Herzegovina in regards to availability and adequacy of financial products for these businesses. The results indicate that entrepreneurs in B&H rarely use government funds as a source of financing business activities, which is mostly caused by insufficient funds and inefficient government procedures.

Full Text Available The investigation on obesity and associated disorders have changed from an scenario in which genome drove the phenotype to a dynamic setup in which prenatal and early-postnatal conditions are determinant. However, research in human beings is difficult due to confounding factors (lifestyle and socioeconomic heterogeneity plus ethical issues. Hence, there is currently an intensive effort for developing adequate preclinical models, aiming for an adequate combination of basic studies in rodent models and specific preclinical studies in large animals. The results of these research strategies may increase the identification and development of contrasted biomarkers and therapeutic targets.

Respect in Kant’s Tugendlehre and its place in contemporary ethics

Directory of Open Access Journals (Sweden)

Darlei Dall'Agnol

2017-12-01

Full Text Available The paper examines Kant’s conception of respect, especially in his work Metaphysical first principles of the doctrine of virtue (briefly Tugendlehre or Doctrine of Virtue, the second part of his The Metaphysics of Morals, and its place in contemporary ethics. The main question it asks is this: is respect just a feeling, a particular virtue or a moral duty/right? The initial hypothesis is that, in the relevant sense, respect is so to speak a “dutright,” that is, a duty that is at the same time a right. It leads to a fundamental principle, namely respect for persons, defining ‘person’ as a bearer of rights/obligations. Leaving Kant’s metaphysical commitments aside, it shows that this is one of the most important Kantian contributions to contemporary ethics

Full Text Available According to a Zulu proverb a human being can only become truly human because of others. Each person can only become more human, more himself- regardless of his sex - through the co-involvement of others. It is the love for one’s neighbour and the respect one has for him/her as a person which makes one consider the other party's feelings, viewpoints and circumstances. In order to arrive at a situation of peaceful coexistence it is important to realize that human attitudes and a mature life style evolve through a process of learning and interaction with others. It is a timeconsuming and costly process which starts at infancy and continues throughout someone's life. Instruction concerning interpersonal relations and the teaching of respect cannot be confined to individual lessons or working sessions at home or in school. Discussions and conversations concerning interpersonal relations need to form an integral and natural part of a child’s life within the home environment and throughout the pupil's school career. It is senseless if educators talk about the importance of teaching respect only to reveal disrespectful behaviour themselves, or to talk about the importance of self-esteem in the paying of respect whilst causing children to feel negative about themselves. To be able to express respect to other human beings, one needs to be respected. A child needs to experience how it feels when homage is paid. The following rule of life applies in this regard: one can never give if one has never received respect.

cm from the previously described reference line had mean values of 2.0 ± 1.0 cm (range 1.3 to 3.0 cm), 0.9 ± 3.9 cm (range -1.9 to 5.1 cm), and 1.8 ± 2.1 cm (range -0.8 to 3.5 cm), respectively. Ten of 22 (45%) patients would have had inadequate nodal irradiation if their fields had been designed according to standard GOG parameters. In all cases, these incompletely irradiated lymph nodes were from the lowest of the lateral external iliac group. Conclusions: Great variability in pelvic lymph node location is demonstrated when LAG is used to directly visualize their location. Bony structures are inaccurate landmarks for pelvic lymph node position. The GOG standard pelvic fields are not consistently adequate to cover all lateral external iliac lymph nodes, although the clinical significance of this subgroup of lymph nodes is not known. At this time, LAG remains the ideal radiographic modality to define anatomic location of regional lymph nodes for pelvic RT treatment planning. The clinical importance of the most lateral group of external iliac lymph nodes in various stages of cervical cancer represents a potential area of future research

Changes in Family Income around the Time of Birth of Children in Germany between 1985 and 2004

Directory of Open Access Journals (Sweden)

Full Text Available While the course and the determinants of fertility behaviour have been investigated intensively, the monetary consequences of birth have hardly been considered empirically to date. Therefore, this paper focuses on the short-term (equivalent household income changes around the time of births in a longitudinal perspective and examines them for their causes. For the analyses of the longitudinal data (GSOEP-Data 1984-2005, fixed effects panel regression models were computed. The results show that the short-term socioeconomic consequences of birth have clearly increased in the last two decades and first births in particular are associated with disproportionately severe socioeconomic consequences, while further births are rarely accompanied by negative changes in the households’ socioeconomic situations. Furthermore, household income losses attributable to births only arise in double income households and increase gradually in line with a rising level of household income before birth. Hence, the analyses suggest the need for more adequate state assistance with respect to family support. Beside the provision of adequate infrastructural conditions which allow mothers to be employed, also the payments to compensate for child-related costs (“Kindergeld” should be – in contrast to the present practice in Germany – increased and re-adjusted with respect to the child’s position in the birth sequence.

We examined whether public schools in states with specific and stringent physical education (PE) laws, as assessed by the Physical Education-Related State Policy Classification System (PERSPCS), available on the Classification of Laws Associated with School Students (C.L.A.S.S.) Web site, reported more weekly PE time in the most recent School Health Policies and Programs Survey (SHPPS). Schools (n=410) were grouped by their state's PERSPCS time requirement scores (none, nonspecific requirement, or specific requirement). Average weekly school-level PE was calculated using the SHPPS-reported PE minutes. Weighted analyses determined if PE minutes/week differed by PERSPCS group. Schools in states with specific requirement laws averaged over 27 and 60 more PE minutes/week at the elementary and middle school levels, respectively, compared with schools within states with nonspecific laws and over 40 and 60 more PE minutes per week, respectively, compared with elementary and middle schools in states with no laws. High school results were nonsignificant. Public health guidelines recommend at least 60 minutes of daily physical activity for children, and PE may further this goal. Strong codified law with specific time requirements for PE may be an important tool contributing toward adequate PE time and daily physical activity recommendations.

Quadratic time dependent Hamiltonians and separation of variables

International Nuclear Information System (INIS)

Anzaldo-Meneses, A.

2017-01-01

Time dependent quantum problems defined by quadratic Hamiltonians are solved using canonical transformations. The Green’s function is obtained and a comparison with the classical Hamilton–Jacobi method leads to important geometrical insights like exterior differential systems, Monge cones and time dependent Gaussian metrics. The Wei–Norman approach is applied using unitary transformations defined in terms of generators of the associated Lie groups, here the semi-direct product of the Heisenberg group and the symplectic group. A new explicit relation for the unitary transformations is given in terms of a finite product of elementary transformations. The sequential application of adequate sets of unitary transformations leads naturally to a new separation of variables method for time dependent Hamiltonians, which is shown to be related to the Inönü–Wigner contraction of Lie groups. The new method allows also a better understanding of interacting particles or coupled modes and opens an alternative way to analyze topological phases in driven systems. - Highlights: • Exact unitary transformation reducing time dependent quadratic quantum Hamiltonian to zero. • New separation of variables method and simultaneous uncoupling of modes. • Explicit examples of transformations for one to four dimensional problems. • New general evolution equation for quadratic form in the action, respectively Green’s function.

What’s the time? About the pertinence to speak of historical time

Directory of Open Access Journals (Sweden)

Antonio GÓMEZ RAMOS

2012-02-01

Full Text Available This paper wants to suggest a defininition of the philosophy of history as a determination of historical time, or at the question about what is the present time. I draw on Norbert Elias’ sociological conception of time, which aims at desontologizing time and considering it as an instrument which humans use for organizing their actions. I suggest that historical time, and philosophy of history, is also a conceptual instrument for organizing and understanding the complexity of human interactions in Modernity. This means that there is a double sensitivity for time in modern society: as consciousness of qualitative time and as technically measured time. Finally, I argue that Heidegger’s and Benjamin’s are the most adequate theories in the Xxth century for approaching a definition of historical time

This study compared the efficacy and safety of amlodipine/benazepril (10/40 mg/day and 10/20 mg/day) with amlodipine 10 mg/day in patients whose blood pressure (BP) was not adequately controlled with amlodipine monotherapy. After a lead-in period with amlodipine monotherapy, 812 non-responder patients (mean sitting diastolic BP > or =95 mmHg) were randomized to one of three treatment groups. Ambulatory BP monitoring was conducted in 276 patients. Treatment with amlodipine/benazepril 10/40 mg/day and 10/20 mg/day resulted in a decrease of mean sitting systolic and mean sitting diastolic BP by 13.3/12.7 mmHg and 12.1/11.6 mmHg, respectively, compared with monotherapy (6.6/8.5 mmHg) (p benazepril 10/40 mg/day and 10/20 mg/day decreased ambulatory systolic and diastolic BP by 9.9/6.7 mmHg and 7.4/5.2 mmHg compared with monotherapy (p benazepril combinations compared with monotherapy (4.5%, 5.5% vs. 9.2%, respectively, p=NS). No significant metabolic side-effects were noted among the combination groups. Amlodipine/benazepril combinations were well tolerated and resulted in significant BP reductions and better BP responder rates than amlodipine monotherapy.

To investigate the performance of a new software-based colonoscopy quality assessment system. The software-based system employs a novel image processing algorithm which detects the levels of image clarity, withdrawal velocity, and level of the bowel preparation in a real-time fashion from live video signal. Threshold levels of image blurriness and the withdrawal velocity below which the visualization could be considered adequate have initially been determined arbitrarily by review of sample colonoscopy videos by two experienced endoscopists. Subsequently, an overall colonoscopy quality rating was computed based on the percentage of the withdrawal time with adequate visualization (scored 1-5; 1, when the percentage was 1%-20%; 2, when the percentage was 21%-40%, etc.). In order to test the proposed velocity and blurriness thresholds, screening colonoscopy withdrawal videos from a specialized ambulatory colon cancer screening center were collected, automatically processed and rated. Quality ratings on the withdrawal were compared to the insertion in the same patients. Then, 3 experienced endoscopists reviewed the collected videos in a blinded fashion and rated the overall quality of each withdrawal (scored 1-5; 1, poor; 3, average; 5, excellent) based on 3 major aspects: image quality, colon preparation, and withdrawal velocity. The automated quality ratings were compared to the averaged endoscopist quality ratings using Spearman correlation coefficient. Fourteen screening colonoscopies were assessed. Adenomatous polyps were detected in 4/14 (29%) of the collected colonoscopy video samples. As a proof of concept, the Colometer software rated colonoscope withdrawal as having better visualization than the insertion in the 10 videos which did not have any polyps (average percent time with adequate visualization: 79% ± 5% for withdrawal and 50% ± 14% for insertion, P quality rating from the automated system and the reviewers was 3.45 [interquartile range (IQR), 3

The objective of the study was to determine the effects of feeding zinc sufficient and zinc deficient rations on taste sensitivity and zinc contents of selected organs in rats. The 36 Sprague-Dawley male weanling rats were divided into 2 groups and fed zinc deficient or zinc adequate rations. The animals were subjected to 4 trial periods in which a choice of deionized distilled water or a solution of quinine sulfate at 1.28 x 10 -6 was given. A randomized schedule for rat sacrifice was used. No differences were found between zinc deficient and zinc adequate rats in taste preference aversion scores for quinine sulfate in the first three trial periods; however, in the last trial period rats in the zinc sufficient group drank somewhat less water containing quinine sulfate as a percentage of total water consumption than did rats fed the zinc deficient ration. Significantly higher zinc contents of kidney, brain and parotid salivary glands were seen in zinc adequate rats compared to zinc deficient rats at the end of the study. However, liver and tongue zinc levels were lower for both groups at the close of the study than were those of rats sacrificed at the beginning of the study

Suggestions for an adequate risk communication - experiences based on German epidemiological studies on childhood cancer and neighbourhood to nuclear power plants

2006-01-01

From the example of the German studies on childhood cancer in the vicinity of nuclear power plants general principles for adequate risk communication could be derived. It is particularly important to explain the complexity of the issue to the public in an adequate way, when dealing with topics of such an emotionally loaded nature. Some rules are required, when explaining the nature of risk to the layman, the press, politicians, or scientists from other fields. The main principle is to create a basis of trustfulness, whereupon results can be presented. In this contribution we derive general and proven specific recommendations for adequate risk communication on the basis of experiences made at the German Childhood Cancer Registry. (orig.)

Thin-film wearable electronics are required to be directly laminated on to human skin for reliable, sensitive bio-sensing but with minimal irritation to the user after long-time use. Excellent heat management films with strongly anisotropic thermal conductivity (K) and adequate breathability are increasingly desirable for shielding the skin from heating while allowing the skin to breathe properly. Here, interfacial self-assembly of a graphene oxide (GO) film covering an ambient-dried bacterial cellulose aerogel (AD-BCA) film followed by laser reduction was proposed to prepare laser-reduced GO (L-rGO)/AD-BCA bilayered films. The AD-BCA substrate provides low cross-plane K (K ⊥  ≈  0.052 W mK‑1), high breathability, and high compressive and tensile resistance by ‘partially’ inheriting the pore structure from bacterial cellulose (BC) gel. The introduction of an upper L-rGO film, which is only 0.31 wt% content, dramatically increases the in-plane K (K // ) from 0.3 W mK‑1 in AD-BCA to 10.72 W mK‑1 owing to the highly in-plane oriented, continuous, uniform assembling geometry of the GO film; while K ⊥ decreases to a lower value of 0.033 W mK‑1, mainly owing to the air pockets between L-rGO multilayers caused by the laser reduction. The bilayered films achieve a K // /K ⊥ of 325, which is substantially larger even than that of graphite and similar polymer composites. They permit high transmission rates for water vapor (416.78 g/m2/day, >204 g/m2/day of normal skin) and O2 (449.35 cm3/m2/day). The combination of strongly anisotropic thermal conductivity and adequate breathability facilitates applications in heat management in on-skin electronics.

Launched in a previous issue of the Bulletin (see here), the 'Respect@CERN' campaign has triggered some rich and varied reactions, and contributions received from colleagues have covered a wide range of themes that extend from the basic “golden rule of treating others as you would have them treat you” to some very specific observations of respectful behaviour in the CERN context.   “To me, respect is the core of all relationships, all exchanges: we cannot work together and achieve results without it,” says one colleague, while another underlines the equally important dimension of projecting and preserving one’s own self-respect where “whether or not we sleep well at night depends on whether or not we feel that we have been true to ourselves that day”. Respect in the workplace is different from everyday respect in that it is based on an “earned privilege where each colleague has been selected for ...

Compressed sensing (CS) acceleration has been theorized for slice encoding for metal artifact correction (SEMAC), but has not been shown to be feasible. Therefore, we tested the hypothesis that CS-SEMAC is feasible for MRI of metal-on-metal hip resurfacing implants. Following prospective institutional review board approval, 22 subjects with metal-on-metal hip resurfacing implants underwent 1.5 T MRI. We compared CS-SEMAC prototype, high-bandwidth TSE, and SEMAC sequences with acquisition times of 4-5, 4-5 and 10-12 min, respectively. Outcome measures included bone-implant interfaces, image quality, periprosthetic structures, artifact size, and signal- and contrast-to-noise ratios (SNR and CNR). Using Friedman, repeated measures analysis of variances, and Cohen's weighted kappa tests, Bonferroni-corrected p-values of 0.005 and less were considered statistically significant. There was no statistical difference of outcomes measures of SEMAC and CS-SEMAC images. Visibility of implant-bone interfaces and pseudocapsule as well as fat suppression and metal reduction were ''adequate'' to ''good'' on CS-SEMAC and ''non-diagnostic'' to ''adequate'' on high-BW TSE (p < 0.001, respectively). SEMAC and CS-SEMAC showed mild blur and ripple artifacts. The metal artifact size was 63 % larger for high-BW TSE as compared to SEMAC and CS-SEMAC (p < 0.0001, respectively). CNRs were sufficiently high and statistically similar, with the exception of CNR of fluid and muscle and CNR of fluid and tendon, which were higher on intermediate-weighted high-BW TSE (p < 0.005, respectively). Compressed sensing acceleration enables the time-neutral use of SEMAC for MRI of metal-on-metal hip resurfacing implants when compared to high-BW TSE and image quality similar to conventional SEMAC.

Effects of the antituberculous drug ethambutol on zinc absorption, turnover and distribution in rats fed diet marginal and adequate in zinc

Ethambutol, (CH/sub 3/CH/sub 2/-CH(CH/sub 2/OH)-NH-CH/sub 2/)/sub 2/ (EMB), is an oral antituberculous agent that is administered therapeutically over extended time periods. It has chelating properties and may affect mineral metabolism. Male weanling Sprague-Dawley rats received 0, 400 or 600 mg EMB per kilogram body weight daily by gavage for 30 d. They were fed a casein-based diet with either adequate (49 ppm) or marginal (11 ppm) zinc. Both adequate-Zn (AZn) and marginal-Zn (MZn) rats receiving EMB showed alopecia and dose-dependent reductions in feed intake, weight gain and feed efficiency. None of these changes was seen in rats fed the MZn diet without EMB. Serum and tissue zinc levels were similar in rats not receiving EMB, regardless of the dietary zinc level. Serum zinc was consistently lower in AZn and MZn rats receiving EMB than in rats without EMB. Apparent zinc absorption, measured by /sup 65/Zn balance, was higher in AZn rats receiving EMB than in AZn rats without EMB. Thus, changes in absorption could not account for lower serum zinc levels in EMB-treated rats. However, /sup 65/Zn turnover was also higher in EMB groups. This suggests that EMB may have increased urinary zinc losses resulting in reduced circulating zinc and a consequent increase in zinc absorption.

Using travel times to simulate multi-dimensional bioreactive transport in time-periodic flows.

Science.gov (United States)

Sanz-Prat, Alicia; Lu, Chuanhe; Finkel, Michael; Cirpka, Olaf A

2016-04-01

In travel-time models, the spatially explicit description of reactive transport is replaced by associating reactive-species concentrations with the travel time or groundwater age at all locations. These models have been shown adequate for reactive transport in river-bank filtration under steady-state flow conditions. Dynamic hydrological conditions, however, can lead to fluctuations of infiltration velocities, putting the validity of travel-time models into question. In transient flow, the local travel-time distributions change with time. We show that a modified version of travel-time based reactive transport models is valid if only the magnitude of the velocity fluctuates, whereas its spatial orientation remains constant. We simulate nonlinear, one-dimensional, bioreactive transport involving oxygen, nitrate, dissolved organic carbon, aerobic and denitrifying bacteria, considering periodic fluctuations of velocity. These fluctuations make the bioreactive system pulsate: The aerobic zone decreases at times of low velocity and increases at those of high velocity. For the case of diurnal fluctuations, the biomass concentrations cannot follow the hydrological fluctuations and a transition zone containing both aerobic and obligatory denitrifying bacteria is established, whereas a clear separation of the two types of bacteria prevails in the case of seasonal velocity fluctuations. We map the 1-D results to a heterogeneous, two-dimensional domain by means of the mean groundwater age for steady-state flow in both domains. The mapped results are compared to simulation results of spatially explicit, two-dimensional, advective-dispersive-bioreactive transport subject to the same relative fluctuations of velocity as in the one-dimensional model. The agreement between the mapped 1-D and the explicit 2-D results is excellent. We conclude that travel-time models of nonlinear bioreactive transport are adequate in systems of time-periodic flow if the flow direction does not change

An adequate vitamin D status, as measured by serum 25-hydroxyvitamin D (25(OH)D) concentration, is important in humans for maintenance of healthy bones and muscle function. Serum 25(OH)D concentration was assessed in participants from Melbourne, Australia (37.81S, 144.96E), who were provided with the current Australian guidelines on sun exposure for 25(OH)D adequacy (25(OH)D ≥50 nmol/L). Participants were interviewed in February (summer, n=104) and August (winter, n=99) of 2013. Serum 25(OH)D concentration was examined as a function of measures of sun exposure and sun protection habits with control of key characteristics such as dietary intake of vitamin D, body mass index (BMI) and skin colour, that may modify this relationship. The mean 25(OH)D concentration in participants who complied with the current sun exposure guidelines was 67.3 nmol/L in summer and 41.9 nmol/L in winter. At the end of the study, 69.3% of participants who complied with the summer sun exposure guidelines were 25(OH)D adequate, while only 27.6% of participants who complied with the winter sun exposure guidelines were 25(OH)D adequate at the end of the study.

What deserves our respect? Reexamination of respect for autonomy in the context of the management of chronic conditions.

Science.gov (United States)

Enzo, Aya; Okita, Taketoshi; Asai, Atsushi

2018-05-29

The global increase in patients with chronic conditions has led to increased interest in ethical issues regarding such conditions. A basic biomedical principle-respect for autonomy-is being reexamined more critically in its clinical implications. New accounts of this basic principle are being proposed. While new accounts of respect for autonomy do underpin the design of many public programs and policies worldwide, addressing both chronic disease management and health promotion, the risk of applying such new accounts to clinical setting remain understudied. However, the application of new accounts of respect for autonomy to clinical settings could support disrespectful attitudes toward or undue interference with patients with chronic conditions. Reconsidering autonomy and respect using Kantian accounts, this paper proposes respect for persons as an alternative basic bioethical principle to respect for autonomy. Unlike the principle of respect for persons in the Belmont Report, our principle involves respecting any patient's decisions, behaviors, emotions, or life-style regardless of his or her "autonomous" capabilities. Thus, attitudes toward patients should be no different irrespective of the assessment of their decisional or executive capabilities.

Overall, yogurt consumers had a significantly higher mean intake of energy, calcium and percentage of energy from total sugars whereas the mean percentage of energy from total fat, saturated fatty acid and total carbohydrate were significantly (p yogurt consumers than in non-consumers, (60.58 ± 0.33 vs. 58.58 ± 0.19, p yogurt consumers. The items of calcium, potassium and riboflavin showed the major percentage variation between consumers and non-consumers. Yogurt consumers were more likely to have adequate intakes of vitamins and minerals, and a higher quality score of the diet.

A model for determining when an analysis contains sufficient detail to provide adequate NEPA coverage for a proposed action

International Nuclear Information System (INIS)

Eccleston, C.H.

1994-11-01

Neither the National Environmental Policy Act (NEPA) nor its subsequent regulations provide substantive guidance for determining the Level of detail, discussion, and analysis that is sufficient to adequately cover a proposed action. Yet, decisionmakers are routinely confronted with the problem of making such determinations. Experience has shown that no two decisionmakers are Likely to completely agree on the amount of discussion that is sufficient to adequately cover a proposed action. one decisionmaker may determine that a certain Level of analysis is adequate, while another may conclude the exact opposite. Achieving a consensus within the agency and among the public can be problematic. Lacking definitive guidance, decisionmakers and critics alike may point to a universe of potential factors as the basis for defending their claim that an action is or is not adequately covered. Experience indicates that assertions are often based on ambiguous opinions that can be neither proved nor disproved. Lack of definitive guidance slows the decisionmaking process and can result in project delays. Furthermore, it can also Lead to inconsistencies in decisionmaking, inappropriate Levels of NEPA documentation, and increased risk of a project being challenged for inadequate coverage. A more systematic and less subjective approach for making such determinations is obviously needed. A paradigm for reducing the degree of subjectivity inherent in such decisions is presented in the following paper. The model is specifically designed to expedite the decisionmaking process by providing a systematic approach for making these determination. In many cases, agencies may find that using this model can reduce the analysis and size of NEPA documents

The leap into the global market is not easy when it involves a provincial family business. This article demonstrates how adequate planning is fundamental in a small and medium-sized enterprise (SME) with the tight budget they have available to them, in order to be able to differentiate themselves in a highly competitive market, taking into accounts the benefits and risks involved. The Information Technology (IT) tools put in place will give the necessary support and allow for the possibility of increasing and improving the infrastructure as the company requires. An adequate strategy for the future to increases sales would be e-marketing techniques as well as the current promotions which contribute to diffusing the brand.

Anorexia, nausea, and vomiting are one of the most frequent symptoms in viral hepatitis patients. These may be due to poorly detoxified substances by dysfunctioned hepatocytes or by gastritis, but the pathophysiology is not totally understood. The symptoms interfere with adequate nutrient intake and are managed by metaclopramide, which accelerates gastric emptying. Thus delayed gastric emptying may well be a contributing factor to such symptoms. To determine such a relationship, we measured gastric emptying time in 11 normal subjects, 9 acute (AVH), and 12 chronic B viral hepatitis (CVH) patients. All were males with a mean age of 23 years. An egg was labeled with 0.5 mCi of 99m Tc-sulfur colloid, fried, then eaten between 2 slices of bread with 100 cc of water. Anterior and posterior images were taken at 20 minute intervals over a 2 hour period. A geometric mean of activity pertaining to the gastric region was measured, and T 1 /2 was calculated from the time activity curve. T 1 /2 for normal the group was 57.8 ± 6.3 minutes while that for the AVH and CVH group was 58.2 ± 8.2 (p=0.40) and 64.1 ± 10.5 (p=0.09), respectively. There was 1 AVH patient and 4 CVH patients with prolonged T 1 /2. Anorexia and nausea was seen in 71% and 46% of the patients, respectively. 80% and 60% of the patients with prolonged T 1 /2 had anorexia and nausea, respectively.

2008-12-01

Full Text Available Abstract Background Delivery of preventive health services in primary care is lacking. One of the main barriers is lack of time. We estimated the amount of time primary care physicians spend on important preventive health services. Methods We analyzed a large dataset of primary care (family and internal medicine visits using the National Ambulatory Medical Care Survey (2001–4; analyses were conducted 2007–8. Multiple linear regression was used to estimate the amount of time spent delivering each preventive service, controlling for demographic covariates. Results Preventive visits were longer than chronic care visits (M = 22.4, SD = 11.8, M = 18.9, SD = 9.2, respectively. New patients required more time from physicians. Services on which physicians spent relatively more time were prostate specific antigen (PSA, cholesterol, Papanicolaou (Pap smear, mammography, exercise counseling, and blood pressure. Physicians spent less time than recommended on two "A" rated ("good evidence" services, tobacco cessation and Pap smear (in preventive visits, and one "B" rated ("at least fair evidence" service, nutrition counseling. Physicians spent substantial time on two services that have an "I" rating ("inconclusive evidence of effectiveness", PSA and exercise counseling. Conclusion Even with limited time, physicians address many of the "A" rated services adequately. However, they may be spending less time than recommended for important services, especially smoking cessation, Pap smear, and nutrition counseling. Future research is needed to understand how physicians decide how to allocate their time to address preventive health.

A traumatic central cord syndrome occurring after adequate decompression for cervical spondylosis: biomechanics of injury: case report.

Case report with review of the literature. To present the first case of a central cord syndrome occurring after adequate decompression, and review the mechanics of the cervical spinal cord injury and postoperative biomechanical and anatomic changes occurring after cervical decompressive laminectomy. Cervical spondylosis is a common pathoanatomic occurrence in the elderly population and is thought to be one of the primary causes for a central cord syndrome. Decompressive laminectomy with or without fusion has been a primary treatment for spondylotic disease and is thought to be protective against further injury. To our knowledge, there are no cases of a central cord syndrome occurring after adequate decompression reported in the literature. Case study with extensive review of the literature. The patient underwent C3-C7 cervical laminectomy without complications. After surgery, the patient's spasticity and gait difficulties improved. She was discharged to inpatient rehabilitation for further treatment of upper extremity weakness. The patient fell in the rehabilitation center, with a central cord syndrome despite adequate decompression of her spinal canal. The patient was treated conservatively for the central cord and had minimal improvement. Decompressive laminectomy provides an immediate decompressive effect on the spinal cord as seen by the dorsal migration of the cord, however, the biomechanics of the cervical spine after decompressive laminectomy remain uncertain. This case supports the ongoing research and need for more intensive research on postoperative cervical spine biomechanics, including decompressive laminectomies, decompressive laminectomy and fusion, and laminoplasty.

Teaching about Respect and Tolerance with Presentations on Cultural Values

Full Text Available Teaching students from diverse backgrounds requires more than sufficient. Very often battles occur among students due to not understanding each other’s values. This study presents experience of a teacher who teaches students from diverse religious, ethnic, and cultural groups. As disrespect, misunderstanding and intolerance were common in the class, it was difficult for the teacher to advance respect among the students for diversity. In order to encourage the students to embrace diversity, the teacher made them introduce their cultures through presentations in the classroom. Although at the beginning the students continued to tease each other by making fun of each other’s cultural values, after some time it was discovered that they were entering the classroom with a real respect and tolerance for diversity.

Now you see it. Now you don't: fair balance and adequate provision in advertisements for drugs before and after the switch from prescription to over-the-counter.

The objective of this study was to measure differences in fair balance (benefit and risk statements) and adequate provision (toll-free numbers, Internet URLs, print ad references, and medical professional references) in advertising content for drugs that have switched from prescription to over-the-counter (OTC). The Vanderbilt TV News Archive was used to select products to study, to measure the frequency and placement of ads for those products, and to view advertising content for those products. Unique advertisements (n = 108) for loratadine (Claritin), citirizine (Zyrtec), and omeprazole (Prilosec) were analyzed for the presence of adequate provision statements and for the frequency of benefit, risk, and other statements. OTC ads were shorter than prescription ads by 10.6 seconds but contained the same total number of statements. Most prescription ads (n (RX) = 31) contained toll-free numbers (97%), Internet URLs (94%), medical professional references (100%) and print ad references (68%). Few OTC ads (n (OTC) = 77) contained adequate provision statements: 4% contained toll-free numbers and 10% contained Internet URLs. Prescription ads had similar numbers of benefits (1.5) and risks (1.8) per 30 seconds of ad time, and OTC ads had more benefits (6.6) than risks (1.2) per 30 seconds of ad time. Prescription drug ads contained risk statements that listed specific side effects and explicit harms from taking the product, but OTC ads contained nonspecific risk information and statements that implied risk rather than directly identifying risk. Differences in the Food and Drug Administration (FDA) and Federal Trade Commission (FTC) regulation of advertising affected the balance of risk and benefit information that appeared and the specificity of risk information available.

The yield of adequate and conclusive fine-needle aspiration results in thyroid nodules is uniform across functional and goiter types.

Science.gov (United States)

Liel, Y

1999-01-01

Relatively little is known about the cytological characteristics of hyperfunctioning (hot) thyroid nodules. Concern has been expressed that fine-needle aspiration (FNA) identifies hot nodules as follicular tumors or indeterminate, and as a consequence patients could be unnecessarily referred for surgery. Between 1979 and 1996, thyroid FNA was performed on 829 patients. Result of thyroid scan was available in 326; 69 (21%) patients had hot, and 257 (79%) had warm or cold thyroid nodules. Nodules in each of these major groups were divided into 2 subgroups: clinically solitary nodules and dominant nodules in multinodular goiters (MNG). The frequencies of adequate versus inadequate FNA samples, and of conclusive versus indeterminate FNA results were determined separately for each of the groups and subgroups. In addition, patients with hot nodules and overt hyperthyroidism were identified and evaluated separately. Bivariate analyses were performed for the frequency of adequate versus inadequate smears and conclusive versus indeterminate results between hot, toxic, and cold-warm nodules, and between solitary nodules and MNG. The frequency of adequate aspirations and conclusive results in the various groups and subgroups was found to be statistically indistinguishable. In conclusion, the yield of adequate samples and the rate of conclusive results of FNA in thyroid nodules is similar, irrespective of the functional state or of goiter presentation. Hot thyroid nodules do not seem to produce an increase in the rate of inadequate or indeterminate FNA results, and therefore, do not affect the overall performance of thyroid FNA.

Perceived competence and warmth influence respect, liking and trust in work relations

Full Text Available Many studies confirmed the positive effect of trust on human relations and performance in organizations. As a social judgment, trust should be related to perceived competence and warmth as two basic dimensions of person perception. Surprisingly, to date no attempts have been made to examine the influence of attributed competence and warmth on social judgments in interpersonal relations at work. To this end, we examine the influence of perceived competence and warmth on trust, liking and respect in upward and downward work relations. A study involving 190 middle-stage managers revealed that the two fundamental dimensions of social cognition (competence and warmth influence respect, liking and trust. Competence had a stronger effect on respect than warmth; the opposite was true for liking. Trust was conditioned by both competence and warmth to an equal, high extent. At the same time, warmth expressed by supervisors led to higher results in liking, respect and trust in them than warmth expressed by subordinates.

Europe's gas consumption and imports to increase with adequate low cost supplies

International Nuclear Information System (INIS)

Odell, P.R.

1997-01-01

Gas in Europe has always been sold above its long-run supply price. Lower prices, however, still permit profitable indigeneous supply expansion. As further reductions in production and transport costs from technological advances are expected, this will continue based on the exploitation of large proven and probable reserves. By 2025, indigeneous output will be 60% up on 1995. Nevertheless, an average 2.2%/annum growth in gas demand will increase import dependence from 130 to 320 BCM over this period. Future international oil prices indicate gas-equivalent border values adequate to secure profitable supply from a range of external sources, leading to continuing competition for markets and the diversification of imports.

Selection of adequate site location during early stages of construction project management: A multi-criteria decision analysis approach

Science.gov (United States)

Marović, Ivan; Hanak, Tomaš

2017-10-01

In the management of construction projects special attention should be given to the planning as the most important phase of decision-making process. Quality decision-making based on adequate and comprehensive collaboration of all involved stakeholders is crucial in project’s early stages. Fundamental reasons for existence of this problem arise from: specific conditions of construction industry (final products are inseparable from the location i.e. location has a strong influence of building design and its structural characteristics as well as technology which will be used during construction), investors’ desires and attitudes, and influence of socioeconomic and environment aspects. Considering all mentioned reasons one can conclude that selection of adequate construction site location for future investment is complex, low structured and multi-criteria problem. To take into account all the dimensions, the proposed model for selection of adequate site location is devised. The model is based on AHP (for designing the decision-making hierarchy) and PROMETHEE (for pairwise comparison of investment locations) methods. As a result of mixing basis feature of both methods, operational synergies can be achieved in multi-criteria decision analysis. Such gives the decision-maker a sense of assurance, knowing that if the procedure proposed by the presented model has been followed, it will lead to a rational decision, carefully and systematically thought out.

The Scope of the Obligation to Respect and to Ensure Respect for International Humanitarian Law

Directory of Open Access Journals (Sweden)

2009-10-01

Full Text Available This article disputes what seems to have become the dominant interpretation of the obligation to respect and to ensure respect for International Humanitarian Law, as codified in common Article 1 of the Geneva Conventions and in Article 1(1 of Additional Protocol I. According to this dominant interpretation, States are required to take all appropriate measures to ensure that IHL is observed universally, including by other States and by non-State actors operating in other States. It is argued that the intention of the High Contracting Parties, coupled with their subsequent practice, calls for a much more narrow interpretation of that obligation. Cet article conteste ce qui semble être devenue l’interprétation dominante de l’obligation de respecter et de faire respecter le Droit International Humanitaire, tel que codifiée à l’article 1 commun aux Conventions de Genève et à l’article 1(1 du Protocole additionnel I. Selon cette interprétation dominante, les États doivent prendre toutes les mesures appropriées pour assurer que le DIH soit observé de façon universelle, y compris par d’autres États ainsi que par des acteurs non étatiques qui opèrent à l’intérieur d’autres États. On soutient que l’intention des Hautes Parties contractantes, en conjonction avec leur pratique subséquentes, laisse entendre une interprétation beaucoup plus étroite de cette obligation.

Full Text Available The United Nations exclaims "all human beings have the right to be treated with dignity and respect" (Annan, 2005, p. 34. Yet, disabled people have long been denied respect in the United States and have been subjected to disability oppression and ableism. For these reasons, the aim of this study was to explore the relationship between respect and disability, particularly respect's impact on the quality of life of disabled people. We had two research questions: (1. what factors predict disabled people being respected? and, (2. how does being respected impact the quality of life of disabled people? To explore these questions, we used secondary Personal Outcome Measures® data from approximately 1,500 disabled people; we analyzed this data to examine relationships between disabled people's interpretations of feeling and being respected, and their quality of life. Our findings revealed being respected had a significant impact on every area of ones' quality of life. Problematically, this also included areas which should be considered non-negotiable fundamental human and civil rights, that should not depend on if, and how, people respect disabled people. While the attitudes underlying the disrespect of disabled people are harmful and problematic, human and civil rights should be inalienable – ones' access to exercise their rights, to safety, to health, and to many other domains should not depend on others' attitudes about, and treatment toward, you.

Can we trust module-respect heuristics?

International Nuclear Information System (INIS)

Mo, Yuchang

2013-01-01

BDD (Binary Decision Diagrams) have proven to be a very efficient tool to assess Fault Trees. However, the size of BDD, and therefore the efficiency of the whole methodology, depends dramatically on the choice of variable ordering. The determination of the best variable ordering is intractable. Therefore, heuristics have been designed to select reasonably good variable orderings. One very important common feature for good static heuristics is to respect modules. In this paper, the notion of module-respect is studied in a systematic way. It is proved that under certain condition there always exists an optimal ordering that respects modules. This condition is that for each module there is always a smallest module BDD and each included module variable appears only once. On the other hand, it is shown that for the trees not satisfying the above sufficient condition the optimal orderings may not be able to be directly generated using module-respect heuristics, even when the shuffling strategy is used.

Osman, Houssam; Parikh, Janak; Patel, Shirali; Jeyarajah, D Rohan

2015-01-01

Background The present study was conducted to assess the preparedness of hepatopancreatobiliary (HPB) fellows upon entering fellowship, identify challenges encountered by HPB fellows during the initial part of their HPB training, and identify potential solutions to these challenges that can be applied during residency training. Methods A questionnaire was distributed to all HPB fellows in accredited HPB fellowship programmes in two consecutive academic years (n = 42). Reponses were then analysed. Results A total of 19 (45%) fellows responded. Prior to their fellowship, 10 (53%) were in surgical residency and the rest were in other surgical fellowships or surgical practice. Thirteen (68%) were graduates of university-based residency programmes. All fellows felt comfortable in performing basic laparoscopic procedures independently at the completion of residency and less comfortable in performing advanced laparoscopy. Eight (42%) fellows cited a combination of inadequate case volume and lack of autonomy during residency as the reasons for this lack of comfort. Thirteen (68%) identified inadequate preoperative workup and management as their biggest fear upon entering practice after general surgery training. A total of 17 (89%) fellows felt they were adequately prepared to enter HPB fellowship. Extra rotations in transplant, vascular or minimally invasive surgery were believed to be most helpful in preparing general surgery residents pursing HPB fellowships. Conclusions Overall, HPB fellows felt themselves to be adequately prepared for fellowship. Advanced laparoscopic procedures and the perioperative management of complex patients are two of the challenges facing HPB fellows. General surgery residents who plan to pursue an HPB fellowship may benefit from spending extra rotations on certain subspecialties. Focus on perioperative workup and management should be an integral part of residency and fellowship training. PMID:25387852

To evaluate the effect of exposure time and image resolution on fractal dimension calculations for determining the optimal range of these two variances. Thirty-one radiographs of the mandibular angle area of sixteen human dry mandibles were taken at different exposure times (0.01, 0.08, 0.16, 0.25, 0.40, 0.64, and 0.80 s). Each radiograph was digitized at 1200 dpi, 8 bit, 256 gray level using a film scanner. We selected an Region of Interest (ROI) that corresponded to the same region as in each radiograph, but the resolution of ROI was degraded to 1000, 800, 600, 500, 400, 300, 200, and 100 dpi. The fractal dimension was calculated by using the tile-counting method for each image, and the calculated values were then compared statistically. As the exposure time and the image resolution increased, the mean value of the fractal dimension decreased, except the case where exposure time was set at 0.01 seconds (alpha = 0.05). The exposure time and image resolution affected the fractal dimension by interaction (p<0.001). When the exposure time was set to either 0.64 seconds or 0.80 seconds, the resulting fractal dimensions were lower, irrespective of image resolution, than at shorter exposure times (alpha = 0.05). The optimal range for exposure time and resolution was determined to be 0.08-0.40 seconds and from 400-1000 dpi, respectively. Adequate exposure time and image resolution is essential for acquiring the fractal dimension using tile-counting method for evaluation of the mandible.

Kusuma, Yadlapalli S; Kumari, Rita; Kaushal, Sonia

2013-10-01

To identify the determinants of adequate antenatal care (ANC) utilisation and institutional deliveries among socio-economically disadvantaged migrants living in Delhi, India. In a cross-sectional survey, 809 rural-urban migrant mothers with a child aged below 2 years were interviewed with a pretested questionnaire. Data on receiving antenatal, delivery and post-natal services, migration history and other social, demographic and income were collected. Recent migrants used the services significantly less than settled migrants. ANC was adequate only among 37% (35% of recent migrant women and 39% of settled migrants). Multinomial regression revealed that being a recent migrant, multiparous, illiterate and married to an unskilled worker were significant risk factors for receiving inadequate ANC. Around 53% of deliveries took place at home. ANC seeking has a strong influence on place of delivery: 70% of births to women who received inadequate ANC were at home. Women who are educated, had their first delivery after the age of 20 years and received adequate ANC were more likely to deliver their child in hospital. Post-natal care is grossly neglected among these groups. Migrant women, particularly recent migrants, are at the risk of not receiving adequate maternal healthcare. Because migration is a continuing phenomenon, measures to mitigate disadvantage due to migration need to be taken in the healthcare system. © 2013 John Wiley & Sons Ltd.

Strategic thinking in turbulent times

Full Text Available The purpose of this paper is to present a structural analysis of strategic thinking spectrum in turbulent times. Business excellence cannot be achieved without a well-defined strategic thinking spectrum able to elaborate and implement strategies in a fast changeable and unpredictable business environment. Strategic thinking means to think for a desirable future which can be ahead 4-5 years of the present time and to make decisions to the best of our knowledge for that unknown business environment. Thus, the research question is: How can we conceive the spectrum of strategic thinking such that we shall be able to deal with a complex and unknown future in achieving a competitive advantage? The methodology used to answer this question is based on metaphorical thinking, and multidimensional analysis. I shall consider four main dimensions: time, complexity, uncertainty, and novelty. On each of these dimensions I shall analyze the known thinking models and their attributes with respect to request formulated in the research question. Then, I shall choose those thinking models that correspond to the future characteristics and integrate them in a continuous spectrum. On each dimension I shall consider three basic thinking models. On the time dimension they are: inertial, dynamic and entropic thinking. On the complexity dimension they are: linear, nonlinear and systemic thinking. On the uncertainty dimension they are: deterministic, probabilistic and chaotic thinking. Finally, on the novelty dimension we have: template, intelligent and creative thinking. Considering all requirements for the unknown future, we conclude that strategic thinking spectrum should contain: entropic, nonlinear and systemic, probabilistic and chaotic, intelligent and creative thinking models. Such a spectrum increases the capacity of our understanding and as a consequence it enhances the capability of making adequate decisions in conditions of complexity and uncertainty.

Intravenous cannulation is usually done in children after inhalational induction with volatile anesthetic agents. The optimum time for safe intravenous cannulation after induction with sevoflurane, oxygen, and nitrous oxide has been studied in premedicated children, but there is no information for the optimum time for cannulation with inhalational induction in children without premedication. The aim of this study was to determine the optimum time for intravenous cannulation after the induction of anesthesia with sevoflurane, oxygen, and nitrous oxide in children without any premedication. This is a prospective, observer-blinded, up-and-down sequential allocation study in unpremedicated ASA grade 1 children aged 2-6 years undergoing elective dental surgery. Intravenous cannulation was attempted after inhalational induction with sevoflurane, oxygen, and nitrous oxide. The timing of cannulation was considered adequate if there was no movement, coughing, or laryngospasm. The cannulation attempt for the first child was set at 4 minutes after the loss of eyelash reflex and the time for intravenous cannulation was determined by the up-and-down method using 15 seconds as step size. Probit test was used to analyze the up-down sequences for the study. The adequate time for effective cannulation after induction with sevoflurane, oxygen, and nitrous oxide in 50% and 95% of patients was 53.02 seconds (95% confidence limits, 20.23-67.76 seconds) and 87.21 seconds (95% confidence limits, 70.77-248.03 seconds), respectively. We recommend waiting for 1 minute 45 seconds (105 seconds) after the loss of eyelash reflex before attempting intravenous cannulation in pediatric patients induced with sevoflurane, oxygen, and nitrous oxide without any premedication. © 2018 John Wiley & Sons Ltd.

The Joint Commission Surgical Care Improvement Project (SCIP) includes performance measures aimed at reducing surgical site infections (SSI). One measure defines approved perioperative antibiotics for general operative procedures. However, there may be a subset of procedures not adequately covered with the use of approved antibiotics. We hypothesized that piperacillin-tazobactam is a more appropriate perioperative antibiotic for pancreaticoduodenectomy (PD). In collaboration with hospital epidemiology and the Division of Infectious Diseases, we retrospectively reviewed records of 34 patients undergoing PD between March and May 2008 who received SCIP-approved perioperative antibiotics and calculated the SSI rate. After changing our perioperative antibiotic to piperacillin-tazobactam, we prospectively reviewed PDs performed between June 2008 and March 2009 and compared the SSI rates before and after the change. For 34 patients from March through May 2008, the SSI rate for PD was 32.4 per 100 cases. Common organisms from wound cultures were Enterobacter and Enterococcus (50.0% and 41.7%, respectively), and these were cefoxitin resistant. From June 2008 through March 2009, 106 PDs were performed. During this period, the SSI rate was 6.6 per 100 surgeries, 80% lower than during March through May 2008 (relative risk, 0.204; 95% confidence interval [CI], 0.086-0.485; P = .0004). Use of piperacillin-tazobactam as a perioperative antibiotic in PD may reduce SSI compared with the use of SCIP-approved antibiotics. Continued evaluation of SCIP performance measures in relationship to patient outcomes is integral to sustained quality improvement. Copyright © 2013 Mosby, Inc. All rights reserved.

Food-Based Dietary Guidelines (FBDGs) are developed to promote healthier eating patterns, but increasing food prices may make healthy eating less affordable. The aim of this study was to design a range of cost-minimized nutritionally adequate health-promoting food baskets (FBs) that help prevent both micronutrient inadequacy and diet-related non-communicable diseases at lowest cost. Average prices for 312 foods were collected within the Greater Copenhagen area. The cost and nutrient content of five different cost-minimized FBs for a family of four were calculated per day using linear programming. The FBs were defined using five different constraints: cultural acceptability (CA), or dietary guidelines (DG), or nutrient recommendations (N), or cultural acceptability and nutrient recommendations (CAN), or dietary guidelines and nutrient recommendations (DGN). The variety and number of foods in each of the resulting five baskets was increased through limiting the relative share of individual foods. The one-day version of N contained only 12 foods at the minimum cost of DKK 27 (€ 3.6). The CA, DG, and DGN were about twice of this and the CAN cost ~DKK 81 (€ 10.8). The baskets with the greater variety of foods contained from 70 (CAN) to 134 (DGN) foods and cost between DKK 60 (€ 8.1, N) and DKK 125 (€ 16.8, DGN). Ensuring that the food baskets cover both dietary guidelines and nutrient recommendations doubled the cost while cultural acceptability (CAN) tripled it. Use of linear programming facilitates the generation of low-cost food baskets that are nutritionally adequate, health promoting, and culturally acceptable.

Recent evidence from prospective cohort studies show a relationship between consumption of dairy foods and cardiovascular diseases (CVDs) and type 2 diabetes mellitus (T2DM). This association highlights the importance of dairy foods consumption in prevention of these diseases and also reduction of associated healthcare costs. The aim of this study was to estimate avoidable healthcare costs of CVD and T2D through adequate dairy foods consumption in Iran. This was a multistage modelling study. We conducted a systematic literature review in PubMed and EMBASE to identify any association between incidence of CVD and T2DM and dairy foods intake, and also associated relative risks. We obtained age- and sex-specific dairy foods consumption level and healthcare expenditures from national surveys and studies. Patient level simulation Markov models were constructed to predict the disease incidence, patient population size and associated healthcare costs for current and optimal dairy foods consumption at different time horizons (1, 5, 10 and 20 years). All parameters including costs and transition probabilities were defined as statistical distributions in the models, and all analyses were conducted by accounting for first and second order uncertainty. The systematic review results indicated that dairy foods consumption was inversely associated with incidence of T2DM, coronary heart disease (CHD) and stroke. We estimated that the introduction of a diet containing 3 servings of dairy foods per day may produce a $0.43 saving in annual per capita healthcare costs in Iran in the first year due to saving in cost of CVD and T2DM treatment. The estimated savings in per capita healthcare costs were $8.42, $39.97 and $190.25 in 5, 10 and 20-years' time, respectively. Corresponding total aggregated avoidable costs for the entire Iranian population within the study time horizons were $33.83, $661.31, $3,138.21 and $14,934.63 million, respectively. Our analysis demonstrated that increasing

Time-Domain Voltage Sag State Estimation Based on the Unscented Kalman Filter for Power Systems with Nonlinear Components

Directory of Open Access Journals (Sweden)

Rafael Cisneros-Magaña

2018-06-01

Full Text Available This paper proposes a time-domain methodology based on the unscented Kalman filter to estimate voltage sags and their characteristics, such as magnitude and duration in power systems represented by nonlinear models. Partial and noisy measurements from the electrical network with nonlinear loads, used as data, are assumed. The characteristics of voltage sags can be calculated in a discrete form with the unscented Kalman filter to estimate all the busbar voltages; being possible to determine the rms voltage magnitude and the voltage sag starting and ending time, respectively. Voltage sag state estimation results can be used to obtain the power quality indices for monitored and unmonitored busbars in the power grid and to design adequate mitigating techniques. The proposed methodology is successfully validated against the results obtained with the time-domain system simulation for the power system with nonlinear components, being the normalized root mean square error less than 3%.

"Children are from heaven" or how today children respect adults

Full Text Available The starting point of the text is a returning to the patriarchal, which is not simply the one that we are witnessing today, in the time of so-called postmodern, postpatriarchal society in its (until now last form. It is a matter of returning to rules, of which the basic premise is that adults are subjects (transcendences, freedoms, activities and children are subjects that are objects for adults (imanences, non-freedoms, pasivities, but which notwithstanding differ from the oldfashioned rules from the past. We attempted to explain this returning, following the example of rules offered by the book Children Are From Heaven – a selfhelp book, published at the end of the nineties of the 20th century, which immediately became the world's bestseller. In addition, our aim was to answer the following questions: What has happened with rules of civilization and good manners, regulating the relations between children and adults today? How have they changed and what has happened with children's or adults's relation to these rules or their performings? How has this relation changed? Considering the mentioned basic premise which implies that children respect adults, we also tried to answer the question: What has happened with the respect, or, how do children respect adults today? Disscussion is presented in the framework of lacanian psychoanalysis.

Its objectives include developing clear definitions of statistical terms, such as plume sampling time, concentration averaging time, receptor exposure time, and other terms often confused with each other or incorrectly specified in hazard assessments; identifying and quantifying situations for which there is no adequate knowledge to predict concentration fluctuations in the near-field, close to sources, and far downwind where dispersion is dominated by atmospheric t

Improving access to adequate pain management in Taiwan.

Science.gov (United States)

Scholten, Willem

2015-06-01

There is a global crisis in access to pain management in the world. WHO estimates that 4.65 billion people live in countries where medical opioid consumption is near to zero. For 2010, WHO considered a per capita consumption of 216.7 mg morphine equivalents adequate, while Taiwan had a per capita consumption of 0.05 mg morphine equivalents in 2007. In Asia, the use of opioids is sensitive because of the Opium Wars in the 19th century and for this reason, the focus of controlled substances policies has been on the prevention of diversion and dependence. However, an optimal public health outcome requires that also the beneficial aspects of these substances are acknowledged. Therefore, WHO recommends a policy based on the Principle of Balance: ensuring access for medical and scientific purposes while preventing diversion, harmful use and dependence. Furthermore, international law requires that countries ensure access to opioid analgesics for medical and scientific purposes. There is evidence that opioid analgesics for chronic pain are not associated with a major risk for developing dependence. Barriers for access can be classified in the categories of overly restrictive laws and regulations; insufficient medical training on pain management and problems related to assessment of medical needs; attitudes like an excessive fear for dependence or diversion; and economic and logistical problems. The GOPI project found many examples of such barriers in Asia. Access to opioid medicines in Taiwan can be improved by analysing the national situation and drafting a plan. The WHO policy guidelines Ensuring Balance in National Policies on Controlled Substances can be helpful for achieving this purpose, as well as international guidelines for pain treatment.

ENSURING ADEQUATE SAFETY WHEN USING HYDROGEN AS A FUEL

Energy Technology Data Exchange (ETDEWEB)

Coutts, D

2007-01-22

Demonstration projects using hydrogen as a fuel are becoming very common. Often these projects rely on project-specific risk evaluations to support project safety decisions. This is necessary because regulations, codes, and standards (hereafter referred to as standards) are just being developed. This paper will review some of the approaches being used in these evolving standards, and techniques which demonstration projects can implement to bridge the gap between current requirements and stakeholder desires. Many of the evolving standards for hydrogen-fuel use performance-based language, which establishes minimum performance and safety objectives, as compared with prescriptive-based language that prescribes specific design solutions. This is being done for several reasons including: (1) concern that establishing specific design solutions too early will stifle invention, (2) sparse performance data necessary to support selection of design approaches, and (3) a risk-adverse public which is unwilling to accept losses that were incurred in developing previous prescriptive design standards. The evolving standards often contain words such as: ''The manufacturer shall implement the measures and provide the information necessary to minimize the risk of endangering a person's safety or health''. This typically implies that the manufacturer or project manager must produce and document an acceptable level of risk. If accomplished using comprehensive and systematic process the demonstration project risk assessment can ease the transition to widespread commercialization. An approach to adequately evaluate and document the safety risk will be presented.

Hydroxyapatite clay for gap filling and adequate bone ingrowth.

Maruyama, M; Terayama, K; Ito, M; Takei, T; Kitagawa, E

1995-03-01

In uncemented total hip arthroplasty, a complete filling of the gap between femoral prosthesis and the host bone is difficult and defects would remain, because the anatomy of the reamed intramedullary canal cannot fit the prosthesis. Therefore, it seems practical to fill the gap with a clay containing hydroxyapatite (HA), which has an osteoconductive character. The clay (HA clay) is made by mixing HA granules (size 0.1 mm or more) having a homogeneous pore distribution and a porosity of 35-48 vol%, and a viscous substance such as a saline solution of sodium alginate (SSSA). In the first experiment, the ratio of HA granules and sodium alginate in SSSA is set for the same handling properties of HA clay and polymethylmethacrylate bone cement (standard viscosity) before hardening. As a result, the ratio is set for 55 wt% of HA in the clay and 12.5 wt% of sodium alginate in SSSA (i.e., HA:sodium alginate:saline solution = 9.8:1:7). In the second study, the gap between the femoral stem and bone model is completely filled with HA clay. However, the gap is not filled only with HA granules or HA granules mixed with saline solution. In the third animal experiment, using an unloaded model, histology shows that HA clay has an osteoconductive property bridging the gap between the implant and the cortical bone without any adverse reaction. HA clay is considered a useful biomaterial to fill the gap with adequate bone ingrowth.

Renewing the Respect for Similarity

Directory of Open Access Journals (Sweden)

Shimon eEdelman

2012-07-01

Full Text Available In psychology, the concept of similarity has traditionally evoked a mixture of respect, stemmingfrom its ubiquity and intuitive appeal, and concern, due to its dependence on the framing of the problemat hand and on its context. We argue for a renewed focus on similarity as an explanatory concept, bysurveying established results and new developments in the theory and methods of similarity-preservingassociative lookup and dimensionality reduction — critical components of many cognitive functions, aswell as of intelligent data management in computer vision. We focus in particular on the growing familyof algorithms that support associative memory by performing hashing that respects local similarity, andon the uses of similarity in representing structured objects and scenes. Insofar as these similarity-basedideas and methods are useful in cognitive modeling and in AI applications, they should be included inthe core conceptual toolkit of computational neuroscience.

Hemodialysis Treatment Time: As Important as it Seems?

Science.gov (United States)

Daugirdas, John T

2017-03-01

Hemodialysis treatment time and Kt/V can both be considered to be primary measures of hemodialysis adequacy, because when either goes to zero, mortality is certain in patients without residual kidney function. Treatment time is important, but it needs to be adjusted based on surface-area-normalized Kt/V, residual kidney function, and expected ultrafiltration rate. Rescaling dose of dialysis measured as Kt/V to body surface area prevents ultrashort dialysis in small patients, women, and children with minimal residual kidney function. Most if not all of the observational studies of associations between outcome and dialysis session length are probably confounded by dose targeting bias. Once adequate Kt/V (taking into account body surface area) has been provided, adequate dialysis time probably is most relevant in terms of limiting the need for a high fluid removal rate. The latter may adversely impact survival by causing recurrent ischemia to cardiovascular and other tissues. There is little high-quality evidence at this time to support a minimum 4-hour treatment time for all patients, regardless of body size, solute removal, or residual kidney function. On the other hand, there is little evidence that prolonging weekly treatment time up to 24 hours per week is harmful. The final decision regarding treatment time is best individualized, based on patient acceptability and experience, residual kidney function, body surface-area-normalized Kt/V, and expected ultrafiltration rate. © 2017 Wiley Periodicals, Inc.

Determining Adequate Averaging Periods and Reference Coordinates for Eddy Covariance Measurements of Surface Heat and Water Vapor Fluxes over Mountainous Terrain

Directory of Open Access Journals (Sweden)

Yi-Ying Chen Ming-Hsu Li

2012-01-01

Full Text Available Two coordinate rotation approaches (double and planar-fit rotations and no rotation, in association with averaging periods of 15 - 480 min, were applied to compute surface heat and water vapor fluxes using the eddy covariance approach. Measurements were conducted in an experimental watershed, the Lien-Hua-Chih (LHC watershed, located in central Taiwan. For no rotation and double rotation approaches, an adequate averaging period of 15 or 30 min was suggested for better energy closure and small variations on energy closure fractions. For the planar-fit rotation approach, an adequate averaging period of 60 or 120 min was recommended, and a typical averaging period of 30 min is not superior to that of 60 or 120 min in terms of better energy closure and small variations on energy closure fractions. The Ogive function analysis revealed that the energy closure was improved with the increase of averaging time by capturing sensible heat fluxes at low-frequency ranges during certain midday hours at LHC site. Seasonal variations of daily energy closure fractions, high in dry season and low in wet season, were found to be associated with the surface dryness and strength of turbulent development. The mismatching of flux footprint areas among flux sensors was suggested as the cause of larger CF variations during the dry seasons as that indicated by the footprint analysis showing scattered source areas. During the wet season, the underestimation of turbulent fluxes by EC observations at the LHC site was attributed to weak turbulence developments as the source area identified by the footprint analysis was closer to the flux tower than those scattered in dry season.

Previous tests of time-reversal invariance via comparisons of polarizations and analyzing powers in nuclear scattering have been examined. It is found that all of these comparisons fail as adequate tests of time-reversal invariance either because of a lack of experimental precision or the lack of sensitivity to any time-reversal symmetry violation

Hall, Jenny S; Mitchell, Mary

2017-06-01

There is currently limited information available on how midwifery students learn to provide care that promotes dignity and respect. In recent years the importance of dignity in healthcare and treating people with respect has received considerable emphasis in both a national and international context. The aim of this discussion paper is to describe an educational workshop that enables learning to promote dignity and respect in maternity care. An interactive workshop, using different creative methods as triggers for learning will be described. Provision of learning opportunities for students around dignity and respect is important to ensure appropriate care is provided in practice. The use of creative methods to inspire has contributed to deep learning within participants. An evaluation of the workshop illustrated how learning impacted on participants practice. Data to support this is presented in this paper. The use of creative teaching approaches in a workshop setting appears to provide an effective learning opportunity around dignified and respectful care. These workshops have evoked a deep emotional response for some participants, and facilitators must be prepared for this outcome to ensure a safe space for learning.

A Comparison and Evaluation of Real-Time Software Systems Modeling Languages

Science.gov (United States)

Evensen, Kenneth D.; Weiss, Kathryn Anne

2010-01-01

A model-driven approach to real-time software systems development enables the conceptualization of software, fostering a more thorough understanding of its often complex architecture and behavior while promoting the documentation and analysis of concerns common to real-time embedded systems such as scheduling, resource allocation, and performance. Several modeling languages have been developed to assist in the model-driven software engineering effort for real-time systems, and these languages are beginning to gain traction with practitioners throughout the aerospace industry. This paper presents a survey of several real-time software system modeling languages, namely the Architectural Analysis and Design Language (AADL), the Unified Modeling Language (UML), Systems Modeling Language (SysML), the Modeling and Analysis of Real-Time Embedded Systems (MARTE) UML profile, and the AADL for UML profile. Each language has its advantages and disadvantages, and in order to adequately describe a real-time software system's architecture, a complementary use of multiple languages is almost certainly necessary. This paper aims to explore these languages in the context of understanding the value each brings to the model-driven software engineering effort and to determine if it is feasible and practical to combine aspects of the various modeling languages to achieve more complete coverage in architectural descriptions. To this end, each language is evaluated with respect to a set of criteria such as scope, formalisms, and architectural coverage. An example is used to help illustrate the capabilities of the various languages.

Choosing an adequate design and analysis in cross-cultural personality research

Jia He

2017-02-01

Full Text Available The flourishing of cross-cultural personality research requires a keen eye for rigorous methodology in such research. With decades of experience in cross-cultural research methods, we have come to appreciate that methodological aspects of such studies are critical for obtaining valid findings. Ill-designed or -conducted studies may produce results that are difficult to interpret. A careful design and analysis can help to deal with various methodological problems in cross-cultural personality studies. Drawing on the extensive knowledge that has been accumulated in cross-cultural and personality research in the past decades, we describe a framework of bias and equivalence that enables the choice of adequate research methods and the avoidance of pitfalls that endanger valid conclusions in cross-cultural personality research. Specifically, we focus on sampling issues, test adaptations, and the combination of emic and etic approaches in this short review article. We encourage researchers to use the tools and experience that are available to considerably enlarge our insights in cross-cultural differences and similarities in personality research.

The span of most chemical shifts recorded in conventional {sup 25}Mg-NMR spectroscopy is ~ 100 ppm. Accordingly, linewidths of ~ 10 ppm or better are desirable to achieve adequate resolution for applications in chemistry. Here we present first high-field {sup 31}Mg- β-NMR measurements of {sup 31}Mg{sup +} ions implanted into a MgO single crystal carried out at the ISAC facility at TRIUMF. The resonances recorded at 2.5 T and 3.5 T show strong linewidth dependency on the applied RF power, ranging from ~ 419 ppm for the highest RF power down to ~ 48 ppm for the lowest one.

Hahn, M.; Fischbach, E.; Fehm, T. [Universitaetsklinikum Tuebingen (DE). Dept. of Obstetrics and Gynecology] (and others)

2011-04-15

Purpose: The objective of the study was to determine whether the various breast biopsy procedures specified in the S 3 guidelines are sensibly represented within the current German health system as considered from a cost evaluation perspective. Materials and Methods: This prospectively designed multicenter study analyzed 221 breast biopsies at 7 institutions from 04/2006 to 01/2007. Core needle biopsies, vacuum-assisted biopsies and surgical open biopsies under sonographic or mammographic guidance were evaluated. During an analysis of process costs, the individual process steps were recorded in diagrammatic form and assigned to the true consumption of resources. The actual resource consumption costs were entered. A process-related breakeven analysis was conducted to check whether the reimbursement of individual biopsy types covers the costs. Results: Only sonographically guided core needle biopsy and surgical open biopsy are adequately reimbursed in the current German health system. All other breast biopsies indicate a negative profit margin. The principal reasons for underfunding are found in the area of reimbursement of investment and non-personnel costs. Conclusion: The reimbursement of breast biopsies must be improved in order to guarantee nationwide care of the population using the breast biopsy methods recommended in the S 3 guidelines and to avoid disincentives with respect to breast biopsy indications.

Do clinical examination gloves provide adequate electrical insulation for safe hands-on defibrillation? I: Resistive properties of nitrile gloves.

Science.gov (United States)

Deakin, Charles D; Lee-Shrewsbury, Victoria; Hogg, Kitwani; Petley, Graham W

2013-07-01

Uninterrupted chest compressions are a key factor in determining resuscitation success. Interruptions to chest compression are often associated with defibrillation, particularly the need to stand clear from the patient during defibrillation. It has been suggested that clinical examination gloves may provide adequate electrical resistance to enable safe hands-on defibrillation in order to minimise interruptions. We therefore examined whether commonly used nitrile clinical examination gloves provide adequate resistance to current flow to enable safe hands-on defibrillation. Clinical examination gloves (Kimberly Clark KC300 Sterling nitrile) worn by members of hospital cardiac arrest teams were collected immediately following termination of resuscitation. To determine the level of protection afforded by visually intact gloves, electrical resistance across the glove was measured by applying a DC voltage across the glove and measuring subsequent resistance. Forty new unused gloves (control) were compared with 28 clinical (non-CPR) gloves and 128 clinical (CPR) gloves. One glove in each group had a visible tear and was excluded from analysis. Control gloves had a minimum resistance of 120 kΩ (median 190 kΩ) compared with 60 kΩ in clinical gloves (both CPR (median 140 kΩ) and non-CPR groups (median 160 kΩ)). Nitrile clinical examination gloves do not provide adequate electrical insulation for the rescuer to safely undertake 'hands-on' defibrillation and when exposed to the physical forces of external chest compression, even greater resistive degradation occurs. Further work is required to identify gloves suitable for safe use for 'hands-on' defibrillation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Thioacetamide-induced cirrhosis in selenium-adequate mice displays rapid and persistent abnormity of hepatic selenoenzymes which are mute to selenium supplementation

International Nuclear Information System (INIS)

Zhang Jinsong; Wang Huali; Yu Hanqing

2007-01-01

Selenium reduction in cirrhosis is frequently reported. The known beneficial effect of selenium supplementation on cirrhosis is probably obtained from nutritionally selenium-deficient subjects. Whether selenium supplementation truly improves cirrhosis in general needs additional experimental investigation. Thioacetamide was used to induce cirrhosis in selenium-adequate and -deficient mice. Selenoenzyme activity and selenium content were measured and the influence of selenium supplementation was evaluated. In Se-adequate mice, thioacetamide-mediated rapid onset of hepatic oxidative stress resulted in an increase in thioredoxin reductase activity and a decrease in both glutathione peroxidase activity and selenium content. The inverse activity of selenoenzymes (i.e. TrxR activity goes up and GPx activity goes down) was persistent and mute to selenium supplementation during the progress of cirrhosis; accordingly, cirrhosis was not improved by selenium supplementation in any period. On the other hand, selenium supplementation to selenium-deficient mice always more efficiently increased hepatic glutathione peroxidase activity and selenium content compared with those treated with thioacetamide, indicating that thioacetamide impairs the liver bioavailability of selenium. Although thioacetamide profoundly affects hepatic selenium status in selenium-adequate mice, selenium supplementation does not modify the changes. Selenium supplementation to cirrhotic subjects with a background of nutritional selenium deficiency can improve selenium status but cannot restore hepatic glutathione peroxidase and selenium to normal levels

Fluxes all of the time? A primer on the temporal representativeness of FLUXNET

Science.gov (United States)

Chu, Housen; Baldocchi, Dennis D.; John, Ranjeet; Wolf, Sebastian; Reichstein, Markus

2017-02-01

FLUXNET, the global network of eddy covariance flux towers, provides the largest synthesized data set of CO2, H2O, and energy fluxes. To achieve the ultimate goal of providing flux information "everywhere and all of the time," studies have attempted to address the representativeness issue, i.e., whether measurements taken in a set of given locations and measurement periods can be extrapolated to a space- and time-explicit extent (e.g., terrestrial globe, 1982-2013 climatological baseline). This study focuses on the temporal representativeness of FLUXNET and tests whether site-specific measurement periods are sufficient to capture the natural variability of climatological and biological conditions. FLUXNET is unevenly representative across sites in terms of the measurement lengths and potentials of extrapolation in time. Similarity of driver conditions among years generally enables the extrapolation of flux information beyond measurement periods. Yet such extrapolation potentials are further constrained by site-specific variability of driver conditions. Several driver variables such as air temperature, diurnal temperature range, potential evapotranspiration, and normalized difference vegetation index had detectable trends and/or breakpoints within the baseline period, and flux measurements generally covered similar and biased conditions in those drivers. About 38% and 60% of FLUXNET sites adequately sampled the mean conditions and interannual variability of all driver conditions, respectively. For long-record sites (≥15 years) the percentages increased to 59% and 69%, respectively. However, the justification of temporal representativeness should not rely solely on the lengths of measurements. Whenever possible, site-specific consideration (e.g., trend, breakpoint, and interannual variability in drivers) should be taken into account.

Efficacy and cytotoxicity of a bleaching gel after short application times on dental enamel.

2013-11-01

This study aimed to evaluate and correlate the efficacy and cytotoxicity of a 35 % hydrogen peroxide (HP) bleaching gel after different application times on dental enamel. Enamel/dentin disks in artificial pulp chambers were placed in wells containing culture medium. The following groups were formed: G1, control (no bleaching); G2 and G3, three or one 15-min bleaching applications, respectively; and G4 and G5, three or one 5-min bleaching applications, respectively. Extracts (culture medium with bleaching gel components) were applied for 60 min on cultured odontoblast-like MDPC-23 cells. Cell metabolism (methyl tetrazolium assay) (Kruskal-Wallis/Mann-Whitney; α = 5 %) and cell morphology (scanning electron microscopy) were analyzed immediately after the bleaching procedures and the trans-enamel and trans-dentinal HP diffusion quantified (one-way analysis of variance/Tukey's test; α = 5 %). The alkaline phosphatase (ALP) activity was evaluated 24 h after the contact time of the extracts with the cells (Kruskal-Wallis/Mann-Whitney; α = 5 %). Tooth color was analyzed before and 24 h after bleaching using a spectrophotometer according to the Commission Internationale de l'Eclairage L*a*b* system (Kruskal-Wallis/Mann-Whitney; α = 0.05). Significant difference (p 0.05). The lowest amount of HP diffusion was observed in G5 (p 0.05). HP diffusion through dental tissues and its cytotoxic effects were proportional to the contact time of the bleaching gel with enamel. However, shorter bleaching times reduced bleaching efficacy. Shortening the in-office tooth bleaching time could be an alternative to minimize the cytotoxic effects of this clinical procedure to pulp tissue. However, the reduced time of bleaching agent application on enamel may not provide adequate esthetic outcome.

Exploring barriers to and enablers of adequate healthcare for Indigenous Australian prisoners with cancer: a scoping review drawing on evidence from Australia, Canada and the United States.

Olds, Jessica; Reilly, Rachel; Yerrell, Paul; Stajic, Janet; Micklem, Jasmine; Morey, Kim; Brown, Alex

International frameworks supported by national principles in Australia stipulate that prisoners should be provided with health services equivalent to those provided in the general community. However, a number of barriers unique to the prison system may hinder the provision of equitable healthcare for this population. In Australia, Indigenous people carry a greater burden of cancer mortality, which the Cancer Data and Aboriginal Disparities (CanDAD) project is seeking to address. During the course of recruiting participants to the CanDAD study, Indigenous Australian prisoners with cancer emerged as an important, under-researched but difficult to access sub-group. This scoping review sought to identify barriers and facilitators of access to adequate and equitable healthcare for Indigenous Australian prisoners with cancer in Australia. This review demonstrated a lack of research and, as such, the scoping review was extended to prisoners with cancer in Australia, New Zealand, the United States and Canada. This approach was taken in order to summarise the existing body of evidence regarding the barriers and facilitators of access to adequate and equitable healthcare for those who are incarcerated and suffering from cancer, and highlight areas that may require further investigation. Eight studies or commentaries were found to meet the inclusion criteria. This limited set of findings pointed to a range of possible barriers faced by prisoners with cancer, including a tension between the prisons' concern with security versus the need for timely access to medical care. Findings identified here offer potential starting points for research and policy development. Further research is needed to better elucidate how barriers to adequate cancer care for prisoners may be identified and overcome, in Australia and internationally. Furthermore, given Indigenous Australians' over-burden of cancer mortality and over-representation in the prison system, further research is needed to

The Joint Commission mandates that hospitals seeking accreditation have a process to define and address disruptive behavior. Leaders at Maimonides Medical Center, Brooklyn, New York, took the initiative to create a code of mutual respect that not only requires respectful behavior, but also encourages sensitivity and awareness to the causes of frustration that often lead to inappropriate behavior. Steps to implementing the code included selecting code advocates, setting up a system for mediating disputes, tracking and addressing operational system issues, providing training for personnel, developing a formal accountability process, and measuring the results.

To assess the efficacy and preparedness of the pre-hospital and hospital emergency medical systems and post graduate trainees in the city to deal with a massive terrorist strike. A cross-sectional survey of postgraduate trainees was conducted at Jinnah Postgraduate Medical Center and Civil Hospital Karachi from 21st July 2007 to 24th July 2007, to evaluate the preparedness and self identified deficiencies of doctors involved in massive trauma casualty management. To assess the pre-hospital care in Karachi, structured telephonic interviews were conducted of administrators of two private run charity based ambulance services. Out of the 90 respondents questioned regarding a self assessment of their training, only 3 (3.3%) of them were confident about their management of bomb blast victims. Eighty-seven (96.6%) of the respondents felt they required some further training (44.4%) or comprehensive training (52.2%). No simulated drills or courses had been conducted for disaster management in the emergency department of the surveyed Hospitals. Most of the ambulance drivers had no paramedic training. Ambulances are equipped with a stretcher and an oxygen cylinder only. No resuscitation measures are available in the ambulances. With an increasing number of terrorist attacks in the country, massive influx of casualties in a relatively short time span has become a regular feature of the Pakistani hospital system. Lack of adequate training at pre-hospital and in hospital levels may translate into increasing morbidities and mortalities. It is imperative that training of junior doctors and paramedical staff be conducted regularly and an effective regional communication base established for efficient interdepartmental coordination.

Everywhere divergent Fourier series with respect to the Walsh system and with respect to multiplicative systems

International Nuclear Information System (INIS)

Bochkarev, S V

2004-01-01

In this paper a new construction of everywhere divergent Fourier-Walsh series is presented. This construction enables one to halve the gap in the Lebesgue-Orlicz classes between the Schipp-Moon lower bound established by using Kolmogorov's construction and the Sjoelin upper bound obtained by using Carleson's method. Fourier series which are everywhere divergent after a rearrangement are constructed with respect to the Walsh system (and to more general systems of characters) with the best lower bound for the Weyl factor. Some results related to an upper bound of the majorant for partial sums of series with respect to rearranged multiplicative systems are established. The results thus obtained show certain merits of harmonic analysis on the dyadic group in clarifying and overcoming fundamental difficulties in the solution of the main problems of Fourier analysis

In this paper we present a time-parallel algorithm for the 3D neutrons calculation of a transient model in a nuclear reactor core. The neutrons calculation consists in numerically solving the time dependent diffusion approximation equation, which is a simplified transport equation. The numerical resolution is done with finite elements method based on a tetrahedral meshing of the computational domain, representing the reactor core, and time discretization is achieved using a θ-scheme. The transient model presents moving control rods during the time of the reaction. Therefore, cross-sections (piecewise constants) are taken into account by interpolations with respect to the velocity of the control rods. The parallelism across the time is achieved by an adequate use of the parareal in time algorithm to the handled problem. This parallel method is a predictor corrector scheme that iteratively combines the use of two kinds of numerical propagators, one coarse and one fine. Our method is made efficient by means of a coarse solver defined with large time step and fixed position control rods model, while the fine propagator is assumed to be a high order numerical approximation of the full model. The parallel implementation of our method provides a good scalability of the algorithm. Numerical results show the efficiency of the parareal method on large light water reactor transient model corresponding to the Langenbuch–Maurer–Werner benchmark.

2008-09-20

EnergyPlus is a new generation building performance simulation program offering many new modeling capabilities and more accurate performance calculations integrating building components in sub-hourly time steps. However, EnergyPlus runs much slower than the current generation simulation programs. This has become a major barrier to its widespread adoption by the industry. This paper analyzed EnergyPlus run time from comprehensive perspectives to identify key issues and challenges of speeding up EnergyPlus: studying the historical trends of EnergyPlus run time based on the advancement of computers and code improvements to EnergyPlus, comparing EnergyPlus with DOE-2 to understand and quantify the run time differences, identifying key simulation settings and model features that have significant impacts on run time, and performing code profiling to identify which EnergyPlus subroutines consume the most amount of run time. This paper provides recommendations to improve EnergyPlus run time from the modeler?s perspective and adequate computing platforms. Suggestions of software code and architecture changes to improve EnergyPlus run time based on the code profiling results are also discussed.

[Respect of patient's dignity in the hospital].

Science.gov (United States)

Duguet, A-M

2010-12-01

Every code of ethics of health professionals in France considers the respect of dignity as a fundamental duty. The French 2002 Law on patient rights says that the person has the right to respect of dignity and of private life. After a presentation of the articles of ethics codes regarding dignity, this paper presents recommendations to deliver medical care in situations where dignity might be endangered such as for patients hospitalized in psychiatric services without consent, or for medical examination of prisoners or medical care to vulnerable patients unable to express their will, especially in palliative care or at the end of life. Respect of dignity after death is illustrated by the reflection conducted by the Espace Ethique de l'AP-HP (Paris area hospitals) and in the Chart of the mortuary yard. A survey of the patients' letters of complaint received by the emergency service of the Toulouse University Hospital showed that, in five years, there were 188 letters and 18 pointed out infringements to the dignity of the person. The health professional team is now aware of this obligation, and in the accreditation of the hospitals, the respect of dignity is one of the indicators of the quality of medical care.

It engages the objection that Enlightenment theories pose a threat to cultures that reject autonomy and argues that autonomy-based democracy...... is not only compatible with but necessary for respect for cultural diversity. On the basis of an intersubjective epistemology, it argues that people cannot know how to live on mutually respectful terms without engaging in public deliberation and develop some degree of personal autonomy. While freedom...... of expression is indispensable for deliberation and autonomy, this does not mean that people have no obligations regarding how they speak to each other. The moral insights provided by deliberation depend on the participants in the process treating one another with respect. The argument is related to the Danish...

Precise femtosecond laser ablation of dental hard tissue: preliminary investigation on adequate laser parameters

2017-01-01

This work aims at evaluating the possibility of introducing state-of-the-art commercial femtosecond laser system in restorative dentistry by maintaining well-known benefits of lasers for caries removal, but also in overcoming disadvantages such as thermal damage of irradiated substrate. Femtosecond ablation of dental hard tissue is investigated by changing the irradiation parameters (pulsed laser energy, scanning speed and pulse repetition rate), assessed for enamel and dentin. The femtosecond laser system used in this work may be suitable for cavity preparation in dentin and enamel, due to the expected effective ablation and low temperature increase when using ultra short laser pulses. If adequate laser parameters are selected, this system seems to be promising for promoting a laser-assisted, minimally invasive approach in restorative dentistry. (paper)

Evidenced-based, practical food portion sizes for preschool children and how they fit into a well balanced, nutritionally adequate diet.

Healthy eating guidelines for 1-4-year-old children are available but evidence-based portion sizes have not been specified. Parents and early-years providers are concerned about under- or over-feeding young children. The present study aimed to report detailed information about appropriate average portion size ranges and suggest a practical food plan for feeding preschool children, providing adequate nutrient intakes within energy requirements. Two sources of information were used to obtain an appropriate portion size range for the types of foods normally eaten by this age group. Median portions of a variety of foods were combined into a food plan fulfilling healthy eating guidelines regarding the number of servings from each food group. The nutrient and energy content of the plan was assessed and compared with recommended adequate nutrient intakes and percentage energy contributions from macronutrients. UK children, aged 1-4 years, taking part in Avon Longitudinal Study of Parents and Children and National Diet and Nutrition Survey, were used in the present study. Portion size ranges were developed for 164 foods. The theoretical food plan using foods with high to medium nutrient density was shown to provide an adequate intake of all nutrients, except vitamin D, for which there are very few food sources. These practical food portion size ranges could be used both in early years settings and in advice to parents. The food plan emphasises the need to include a variety of nutrient-dense foods if a balanced diet is to be achieved for preschool children. © 2014 The British Dietetic Association Ltd.

Coverage of Adequately Iodized Salt Is Suboptimal and Rice Fortification Using Public Distribution Channels Could Reach Low-Income Households: Findings from a Cross-Sectional Survey of Anganwadi Center Catchment Areas in Telangana, India.

Directory of Open Access Journals (Sweden)

James P Wirth

Full Text Available Food fortification is a cost-effective approach to prevent and control of micronutrient deficiencies in India. A cross-sectional survey of children 0-35 months of age residing in the catchment areas of anganwadi centers in the state of Telangana was conducted to assess the coverage of adequately iodized salt and the potential for rice fortification. Salt samples were collected and tested for iodine concentration using iodometric titration. Information on demographics, household rice consumption, and Telangana's rice sector was collected and interpreted. In households of selected children, 79% of salt samples were found to be adequately iodized. Salt brand and district were significant predictors of inadequately iodized salt. Daily rice consumption among children and women averaged 122 grams and 321 grams per day, respectively. Approximately 28% of households reported consuming rice produced themselves or purchased from a local farmer, 65% purchased rice from a market or shop, 6% got rice from a public distribution system site, and 2% obtained it from a rice mill. In the catchment areas of Telangana's anganwadi centers, there is significant variation in the coverage of adequately iodized salt by district. Future surveys in Telangana should measure the coverage of salt iodization in the general population using quantitative methods. Nonetheless, increasing the adequacy of iodization of smaller salt manufacturers would help achieve universal salt iodization in Telangana. Despite high consumption of rice, our findings suggest that large-scale market-based rice fortification is not feasible in Telangana due to a large proportion of households producing their own rice and highly fragmented rice distribution. Distributing fortified rice via Telangana's public distribution system may be a viable approach to target low-income households, but would only reach a small proportion of the population in Telangana.

Simple first aid following a burn injury has been shown to improve outcome. With this in mind, a prospective study was conducted to evaluate the knowledge of burns first aid amongst parents in South Yorkshire, United Kingdom. This information was used to identify which aspects of burn first aid need to be highlighted in an education campaign and who the target audience should be. A simple mnemonic is suggested to assist parental education on the topic. Parents attending outpatient clinics at Sheffield Children's Hospital were interviewed and asked about the first aid they would provide for a child with a large scald. Removal of hot clothes and jewellery; application of cold water for 10-20 min; obtaining medical advice; and covering the burn with a plastic film or clean cloth were all considered to be ideal responses. Variations in responses in relation to the age and ethnicity of the parent were noted. One hundred and eighty eight parents were included in the questionnaire. Of these, 81% (n=152) were white British and 20% (n=36) were from other ethnic groups. Only 10% (n=18) of all respondent would give all the ideal first aid steps. Less than 40% (n=73) of parents questioned would remove hot clothes and jewellery. There was no significant difference in responses between ethnic groups when assessing knowledge of the need to remove hot soaked clothing. Although 73% (n=137) of parents would run the burn under cool water, only 35% (n=66) would cool the burn for an adequate length of time. White British parents were significantly more likely to run cool water over the burn, and to continue this for the recommended 10-20 min. Whilst 88% (n=165) of parents would seek medical attention, this was significantly less in parents under 20 years old. Finally, 92% (n=173) of parents would protect the wound with appropriate dressings, but of note, 26% (n=9) of parents from minority ethnic groups would potentially impair burn healing by using inappropriate dressings and topical

Background: Although respecting human dignity is a cornerstone of all nursing practices, industrialization has gradually decreased the attention paid to this subject in nursing care. Therefore, the present study aimed to investigate nurses’ commitment to respecting patient dignity in hospitals of Isfahan, Iran. Methods: This descriptive-analytical study was conducted in hospitals of Isfahan. Overall, 401 inpatients were selected by cluster sampling and then selected simple random sampling from different wards. Data were collected through a questionnaire containing the components of patient dignity, that is, patient-nurse relationships, privacy, and independence. All items were scored based on a five-point Likert scale. The collected data were analyzed using descriptive statistics and Chi-square tests. P < 0.05 were considered significant in all analyses. Findings: Most patients (91%) scored their relationships with nurses as good. Moreover, 91.8% of the participants described privacy protection as moderate/good. Only 6.5% of the subjects rated it as excellent. The majority of the patients (84.4%) believed their independence was maintained. These subjects also approved of taking part in decision-making. Conclusion: According to our findings, nurses respected patient dignity to an acceptable level. However, the conditions were less favorable in public hospitals and emergency departments. Nursing authorities and policy makers are thus required to introduce appropriate measures to improve the existing conditions. PMID:28546981

A sample of 596 students in a Michigan high school completed 2 measures of self-esteem (S. Coopersmith, 1967; M. Rosenberg, 1979) and the English translation of the Social Behaviors Scale (M. Loranger, M. Poirier, D. Gauthier, & J. Talon, 1982). Factor analysis of the 36-item Social Behaviors Scale revealed 5 factors appropriate for assessing social respect. Regression analyses revealed that scores for total self-esteem and global self-esteem were significant predictors of total social respect. The scores for total self-esteem were also significantly associated with respect for teachers and for appropriate language. The females reported more respect for teachers, others, appropriate language, and physical property than the males did. The seniors reported more respect for appropriate language, teachers, and others than the freshmen did. Total self-esteem was significantly and negatively associated with respect for waiting and listening. Global self-esteem was significantly and negatively associated with respect for physical property.

Monitoring the eye lens: which dose quantity is adequate?

International Nuclear Information System (INIS)

Behrens, R; Dietze, G

2010-01-01

Recent epidemiological studies suggest a rather low dose threshold (below 0.5 Gy) for the induction of a cataract of the eye lens. Some other studies even assume that there is no threshold at all. Therefore, protection measures have to be optimized and current dose limits for the eye lens may be reduced in the future. The question of which personal dose equivalent quantity is appropriate for monitoring the dose to the eye lens arises from this situation. While in many countries dosemeters calibrated in terms of the dose equivalent quantity H p (0.07) have been seen as being adequate for monitoring the dose to the eye lens, this might be questionable in the case of reduced dose limits and, thus, it may become necessary to use the dose equivalent quantity H p (3) for this purpose. To discuss this question, the dose conversion coefficients for the equivalent dose of the eye lens (in the following eye lens dose) were determined for realistic photon and beta radiation fields and compared with the values of the corresponding conversion coefficients for the different operational quantities. The values obtained lead to the following conclusions: in radiation fields where most of the dose comes from photons, especially x-rays, it is appropriate to use dosemeters calibrated in terms of H p (0.07) on a slab phantom, while in other radiation fields (dominated by beta radiation or unknown contributions of photon and beta radiation) dosemeters calibrated in terms of H p (3) on a slab phantom should be used. As an alternative, dosemeters calibrated in terms of H p (0.07) on a slab phantom could also be used; however, in radiation fields containing beta radiation with the end point energy near 1 MeV, an overestimation of the eye lens dose by up to a factor of 550 is possible.

This year, the World Health Organization focuses on restoring dignity and respect to health care workers. The aim of this study was to investigate the workplace stressors in physicians. The present study was performed in the period 2002 - 2004, among physicians treated in the Health Center Novi Sad. The examinees were asked to fill out a questionnaire--a workplace survey--to identify workplace stressors by using a self-evaluation method The physicians were divided into three groups: those practicing surgery (S), internal medicine (IM) and preventive-diagnostics (PD). Statistical analysis was done using SPSS and STATISTICA software. The sample included 208 physicians with an average age of 40 years (SD = 7,1); average work experience of 22 years (SD = 8,1). 65 physicians from group S and 108 physicians from group IM, identified the following workplace stressors: treating patients in life-threatening situations (47.7%, 30.6%, respectfully); on-call duty (13.8%, 12%); low salary (10.8%, 10.2%); limited diagnostic and therapeutic resources in the IM group. 35 physicians from the DP group identified the following stressors: low salary (25%), treating patients in life-threatening situations and a great number of patients (16%). The analysis of all examined physicians revealed the following workplace stressors: treating patients in life-threatening situations (34.6%), low salary (13%), on-call duty and overtime, and too many patients per physician (11.5%). Restoring the reputation of health workers can be done by providing new equipment to resolve life-threatening situations, by increasing salaries, reducing on-call time, as well as the number of patients. Generally speaking, this should help to improve the quality of work in the health care system, in accordance with the recommendations of the WHO.

Purpose: This research aimed to study the anatomic relationship between the internal jugular vein with the surrounding internal jugular lymph node chain and the underlying bony anatomical structures which are commonly used as landmarks for radiation therapy planning. Methods and Materials: Twelve patients with carcinoma of the head and neck region were studied prospectively. Using our three-dimensional planning system, a beam's-eye view of the internal jugular vein was projected onto a lateral and anterior simulation film. Quantitative measurements were made in every case of the anatomic relationship between the internal jugular vein and the posterior border of the cervical vertebrae and sagittal midline. Results: The distance between the posterior border of the internal jugular vein and the posterior border of the cervical vertebrae ranged between 0 and 2.5 cm. The distances between the sagittal midline and the medial border of the internal jugular veins ranged between 2 and 4 cm. Conclusion: To ensure adequate irradiation of the internal jugular lymph nodes, the posterior border of the lateral radiation therapy upper-neck fields should be placed at least 1 cm posterior to the posterior aspect of the cervical vertebrae. The midline block used in the lower neck anterior field should not exceed 2 cm in width

Full Text Available The value of care giving seems to be at an all-time low. whether it is clinical (bedside or for children and elderly at home (homemakers. Currently, individuals who pass away any opportunity (for themselves to care for another individual instead are considered weak and/or unmotivated. Thus, it is not surprising that modern society often fails to respect the nursing professionals to the extent of underplaying their strengths, skills, and even clinical abilities. While qualities such as kindness, team spirit, and willingness to get their hands dirty are the core of this profession, nursing professionals have a complex variety of set duties, involving drug dosage, trouble-shooting, ongoing patient monitoring, and providing holistic comfort and support to the sick and needy. Beyond classical role, the nursing professional has currently ventured into other roles as well, as a nurse practitioner, administrator, researcher, or even an educator. Thus, considering the wide spectrum of duties performed by nursing professionals, they do deserve more status and power rather than be treated like “ward housewives.”

Time resolution studies using digital constant fraction discrimination

2007-01-01

Digital Pulse Processing (DPP) modules are being increasingly considered to replace modular analog electronics in medium-scale nuclear physics experiments (100-1000s of channels). One major area remains, however, where it has not been convincingly demonstrated that DPP modules are competitive with their analog predecessors-time-of-arrival measurement. While analog discriminators and time-to-amplitude converters can readily achieve coincidence time resolutions in the 300-500 ps range with suitably fast scintillators and Photomultiplier Tubes (PMTs), this capability has not been widely demonstrated with DPPs. Some concern has been expressed, in fact, that such time resolutions are attainable with the 10 ns sampling times that are presently commonly available. In this work, we present time-coincidence measurements taken using a commercially available DPP (the Pixie-4 from XIA LLC) directly coupled to pairs of fast PMTs mated with either LSO or LaBr 3 scintillator crystals and excited by 22 Na γ-ray emissions. Our results, 886 ps for LSO and 576 ps for LaBr 3 , while not matching the best literature results using analog electronics, are already well below 1 ns and fully adequate for a wide variety of experiments. These results are shown not to be limited by the DPPs themselves, which achieved 57 ps time resolution using a pulser, but are degraded in part both by the somewhat limited number of photoelectrons we collected and by a sub-optimum choice of PMT. Analysis further suggests that increasing the sampling speed would further improve performance. We therefore conclude that DPP time-of-arrival resolution is already adequate to supplant analog processing in many applications and that further improvements could be achieved with only modest efforts

Full Text Available Abstract Background Amount of sleep is an important indicator of health and well-being in children and adolescents. Adequate sleep (AS: adequate sleep is defined as 6–8 hours per night regularly is a critical factor in adolescent health and health-related behaviors. The present study was based on a health promotion project previously conducted on adolescents in Tao-Yuan County, Taiwan. The aim was to examine the relationship between AS during schooldays and excessive body weight, frequency of visiting doctors and health-related behaviors among Taiwanese adolescents. Methods A cross-sectional study design, categorical and multivariate data analyses were used. The hypotheses investigated were: high frequency of AS is positively associated with lack of obesity and less frequent visits to doctors; and high frequency AS is positively associated with health-related behavior. Results A total of 656 boys (53.2% and girls (46.8%, ranging in age from 13–18 years were studied between January and June 2004. Three hundred and fifty seven subjects (54% reported that they slept less than the suggested 6–8 hours on schooldays. A significant negative association was found between low sleep and of the following health-related behaviors: (1 life appreciation; (2 taking responsibility for health; (3 adopting healthy diet; (4 effective stress management; (5 regular exercise; and (6 total AHP score. High frequency AS was associated with low frequencies of obesity after potential confounding factors were controlled. Junior high school adolescents reported significantly higher frequencies of AS than high school participants. Gender, family structure, home location and frequency of television watching or computer use were not significantly associated with AS. Conclusion These findings support the proposition that AS is associated with good health status and high-frequency adoption of health-related behavior. Furthermore, these findings suggest that inadequate

Monitoring of cyclosporine (CsA) is critical during the induction of immunosuppressive therapy. Although most centers have incorporated C2 levels, our unit still uses an abbreviated AUC model which includes concentrations at C1, C2, and C6 post-dose (AUC(1-6)). The objective of this study was to compare both strategies of CsA monitoring during the first 30 days after kidney transplantation. The study included 89 recipients induced with CsA microemulsion and steroids. AUC(1-6) profiles were performed around days 3, 10, and 30 after transplantation with a target of 5500 to 6000 ng*h/mL considered therapeutic. For comparison purposes, a value of C2 >/= 1500 ng/mL was also considered therapeutic. Mean C2 and AUC(1-6) values were low dated with biopsy-proven acute rejection episodes (BPAR) during the study period. Twenty patients received living donor kidneys and overall there were 46 females. During this period, 253 AUC(1-6) were performed including 44 (17.4%) below the therapeutic range. When the analysis included only C2, 171 (67.6%) were below the therapeutic target (P AUC(1-6) at day 10 discriminated rejectors versus nonrejectors (5645 +/- 1390 and 8221 +/- 2502, respectively; P = .008). C2 was not significantly different at any time in either group. In this study, abbreviated AUC monitoring more adequately identified patients at risk for acute rejection than C2. Recommended C2 concentration levels need to be redefined in our patients.

Synchronization resources in heterogeneous environments: Time-sharing, real-time and Java

International Nuclear Information System (INIS)

Pereira, A.; Vega, J.; Pacios, L.; Sanchez, E.; Portas, A.

2006-01-01

The asynchronous event distribution system (AEDS) was built to provide synchronization resources within the TJ-II local area network. It is a software system developed to add 'soft synchronization' capabilities to the TJ-II data acquisition, control and analysis environments. 'Soft synchronization' signifies that AEDS is not a real-time system. In fact, AEDS is based on TCP/IP over ETHERNET networks. However, its response time is adequate for practical purposes when synchronization requirements can support some delay between event dispatch and message reception. Event broadcasters (or synchronization servers in AEDS terminology) are Windows computers. Destination computers (or synchronization clients) were also Windows machines in the first version of AEDS. However, this fact imposed a very important limitation on synchronization capabilities. To overcome this situation, synchronization clients for different environments have been added to AEDS: for time-sharing operating systems (Unix and Linux), real-time operating systems (OS-9 and VxWorks) and Java applications. These environments have different synchronization primitives, requiring different approaches to provide the required uniform functionality. This has been achieved with POSIX thread library synchronization primitives (mutex and condition variables) on Unix/Linux systems, IPC mechanisms for concurrent processes on OS-9 and VxWorks real-time operating systems, and 'synchronized-wait/notify' primitives on Java virtual machines

The two-layer geochemical structure of modern biogeochemical provinces and its significance for spatially adequate ecological evaluations and decisions

Science.gov (United States)

Korobova, Elena; Romanov, Sergey

2014-05-01

Contamination of the environment has reached such a scale that ecogeochemical situation in any area can be interpreted now as a result of the combined effect of natural and anthropogenic factors. The areas that appear uncomfortable for a long stay can have natural and anthropogenic genesis, but the spatial structure of such biogeochemical provinces is in any case formed of a combination of natural and technogenic fields of chemical elements. Features of structural organization and the difference in factors and specific time of their formation allow their separation on one hand and help in identification of areas with different ecological risks due to overlay of the two structures on the other. Geochemistry of soil cover reflects the long-term result of the naturally balanced biogeochemical cycles, therefore the soil geochemical maps of the undisturbed areas may serve the basis for evaluation of the natural geochemical background with due regard to the main factors of geochemical differentiation in biosphere. Purposeful and incidental technogenic concentrations and dispersions of chemical elements of specific (mainly mono- or polycentric) structure are also fixed in soils that serve as secondary sources of contamination of the vegetation cover and local food chains. Overlay of the two structures forms specific heterogeneity of modern biogeochemical provinces with different risk for particular groups of people, animals and plants adapted to specific natural geochemical background within particular concentration interval. The developed approach is believed to be helpful for biogeochemical regionalizing of modern biosphere (noosphere) and for spatially adequate ecogeochemical evaluation of the environment and landuse decisions. It allows production of a set of applied geochemical maps such as: 1) health risk due to chemical elements deficiency and technogenic contamination accounting of possible additive effects; 2) adequate soil fertilization and melioration with due

This article deals with the classification of explosion-proof protected induction motors, which are used in hazardous areas, into adequate temperature and efficiency class. Hazardous areas are defined as locations with a potentially explosive atmosphere where explosion may occur due to present of flammable gasses, liquids or combustible dusts (industrial plants, mines, etc.). Electric motors and electrical equipment used in such locations must be specially designed and tested to prevent electrical initiation of explosion due to high surface temperature and arcing contacts. This article presents the basic tests of three-phase explosion-proof protected induction motor with special emphasis on the measuring system and temperature rise test. All the measurements were performed with high-accuracy instrumentation and accessory equipment and carried out at the Institute of energy technology in the Electric machines and drives laboratory and Applied electrical engineering laboratory.

We recently reported that glycated albumin (GA) in patients with Cushing's syndrome is low. In the present study, we examined whether serum albumin (SA)-adjusted GA (SAaGA) is an adequate indicator of glycemic control in patients with Cushing's syndrome. We studied 26 patients with Cushing's syndrome (13 patients without diabetes and 13 patients with diabetes). Twenty six non-diabetic subjects and 26 patients with type 2 diabetes mellitus matched for age, sex and BMI were used as the controls. SAaGA was calculated using the regression formula between SA and GA in non-diabetic patients with Cushing's syndrome and non-diabetic subjects. SA showed a significant correlation with GA in non-diabetic patients with Cushing's syndrome and non-diabetic subjects. GA, but not SAaGA, in non-diabetic patients with Cushing's syndrome was significantly lower than that in the non-diabetic controls. Furthermore, the GA/HbA1c ratio, but not the SAaGA/HbA1c ratio, in diabetic patients with Cushing's syndrome was significantly lower than that in the diabetic controls. The measured GA in the patients with Cushing's syndrome was significantly lower than the estimated GA, but there was no difference between SAaGA and the estimated GA. The present findings suggest that SAaGA is an adequate indicator of the glycemic control in patients with Cushing's syndrome. Copyright © 2014 The Canadian Society of Clinical Chemists.

Are forestation, bio-char and landfilled biomass adequate offsets for the climate effects of burning fossil fuels?

International Nuclear Information System (INIS)

Reijnders, L.

2009-01-01

Forestation and landfilling purpose-grown biomass are not adequate offsets for the CO 2 emission from burning fossil fuels. Their permanence is insufficiently guaranteed and landfilling purpose-grown biomass may even be counterproductive. As to permanence, bio-char may do better than forests or landfilled biomass, but there are major uncertainties about net greenhouse gas emissions linked to the bio-char life cycle, which necessitate suspension of judgement about the adequacy of bio-char addition to soils as an offset for CO 2 emissions from burning fossil fuels.

Ten blood banks were included in the study and classified as 'adequate' (≥80 points, 'partially adequate' (from 50 to 80 points, or 'inadequate' (<50 points. The following components were evaluated: 'donor education' (5 points, 'clinical screening' (40 points, 'laboratory screening' (40 points and 'hemovigilance' (15 points.Results:The overall median score was 49.8 (minimum = 16; maximum = 78. Five blood banks were classified as 'inadequate' and five as 'partially adequate'. The median clinical screening score was 26 (minimum = 16; maximum = 32. The median laboratory screening score was 20 (minimum = 0; maximum = 32. Eight blood banks performed laboratory tests for malaria; six tested all donations. Seven used thick smears, but only one performed this procedure in accordance with Ministry of Health requirements. One service had a Program of External Quality Evaluation for malaria testing. With regard to hemovigilance, two institutions reported having procedures to detect cases of transfusion-transmitted malaria.Conclusion:Malaria is neglected as a blood–borne disease in the blood banks of the Brazilian Amazon region. None of the institutions were classified as 'adequate' in the overall classification or with regard to clinical screening and laboratory screening. Blood bank professionals, the Ministry of Health and Health Surveillance service managers need to pay more attention to this matter so that the safety procedures required by law are complied with.

1977-02-01

With the aid of the radionuclides Mn 56 and Na 24 as tracers, respectively, the following characteristics were investigated for a roller mill and for a tandem air-swept grinding plant: the time of passage of the mill feed material, the retention time distribution in the grinding system (most frequent and mean retention time), and the time required for, respectively, 50%, 90% and 95% of the material to pass, in some instances separately for the three raw material components limestone, clay and sand. In addition, in the case of the air-swept grinding plant the time required for conveying the raw meal sample from the sampling point to the X-ray fluorescence analysis apparatus was determined. The mean retention time of the material in the two roller mills IV and V was 2.93 and 2.55 minutes respectively; for the tandem air-swept grinding plant it was 8 minutes. The time taken for 90% of the mill feed to pass through the mill was 5.5 and 5 minutes for the roller mills respectively and was about 18.3 minutes for the air-swept plant. The dead time vor conveying the raw meal sample to the X-ray fluorescence apparatus, including further grinding of the sample in a vibratory mill, was 12 minutes.

As consequence, CT data to be used for 3D visualization is not only based on 4 row CTs and 16 row CTs but also on 64 row CTs, respectively. The main goal of this study was to examine whether the increased amount of CT detector rows is correlated with improved quality of the 3D images. Material and Methods: All CTs were acquired during routinely performed preoperative evaluation. Overall, there were 12 data sets based on 4 detector row CT, 12 data sets based on 16 detector row CT, and 10 data sets based on 64 detector row CT. Imaging data sets were transferred to the DKFZ Heidelberg using the CHILI teleradiology system. For the analysis all CT scans were examined in a blinded fashion, i.e. both the name of the patient as well as the name of the CT brand were erased. For analysis, the time for segmentation of liver, both portal and hepatic veins as well as the branching depth of portal veins and hepatic veins was recorded automatically. In addition, all results were validated in a blinded fashion based on given quality index. Results: Segmentation of the liver was performed in significantly shorter time (p < 0.01, Kruskal-Wallis test) in the 16 row CT (median 479 s) compared to 4 row CT (median 611 s), and 64 row CT (median 670 s), respectively. The branching depth of the portal vein did not differ significantly among the 3 different data sets (p = 0.37, Kruskal-Wallis test). However, the branching depth of the hepatic veins was significantly better (p = 0.028, Kruskal-Wallis test) in the 4 row CT and 16 row CT compared to 64 row CT. The grading of the quality index was not statistically different for portal veins and hepatic veins (p = 0.80, Kruskal-Wallis test). Even though the total quality index was better for the vessel tree based on 64 row CT data sets (mean scale 2.6) compared to 4 CT row data (mean scale 3.25) and 16 row CT data (mean scale 3.0), these

Full Text Available The paper deals with significance testing of time series co-movement measured via wavelet analysis, namely via the wavelet cross-spectra. This technique is very popular for its better time resolution compare to other techniques. Such approach put in evidence the existence of both long-run and short-run co-movement. In order to have better predictive power it is suitable to support and validate obtained results via some testing approach. We investigate the test of wavelet power cross-spectrum with respect to the Gaussian white noise background with the use of the Bessel function. Our experiment is performed on real data, i.e. seasonally adjusted quarterly data of gross domestic product of the United Kingdom, Korea and G7 countries. To validate the test results we perform Monte Carlo simulation. We describe the advantages and disadvantages of both approaches and formulate recommendations for its using.

National audit of the quality of pain relief provided in emergency departments in Aotearoa, New Zealand: The PRiZED 1 Study.

Pain is a common feature of ED presentations and the timely provision of adequate analgesia is important for patient care. However, there is currently no New Zealand data with respect to this indicator of care quality. The present study aimed to provide a baseline for the quality of care with respect to the provision of timely and adequate analgesia in New Zealand EDs. The present study is a secondary analysis of data initially collected for the Shorter Stays in Emergency Department Study, using a retrospective chart review of 1685 randomly selected ED presentations (2006-2012) from 26 New Zealand public hospital EDs. Of the 1685 charts randomly selected, 1547 (91%) were reviewed from 21 EDs. There were 866 ED presentations with painful conditions, of whom 132 (15%) did not have pain recorded, 205 (24%) did not receive pain relief and 19 (2%) did not have time of analgesia documented leaving 510 (59%) for the analysis of time to analgesia. Four hundred and fifty-seven (53%) did not have pain well documented sufficiently to assess adequacy, leaving 277 (32%) for the analysis of adequacy of analgesia. The median (interquartile range) time to analgesia was 62 (30-134) min and the provision of adequate analgesia was 141/277 (51%, 95% CI: 45-57%); however, there was some variation between hospitals for both outcomes. Although these outcomes are on a par with other countries, this baseline audit has shown both poor documentation and variation in the provision of timely and adequate pain relief in New Zealand EDs, with room for improvement with respect to this quality indicator. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

The pseudo Hermiticity with respect to the exchange operators of N-D complex Hamiltonians is investigated. It is shown that if an N-D Hamiltonian is pseudo Hermitian and any eigenfunction of it retains π α T symmetry then the corresponding eigen value is real, where π α is an exchange operator with respect to the permutation α of coordinates and T is the time reversal operator. We construct a special class of N-D pseudo Hermitian Hamiltonians with respect to exchange operators from both N/2-D and N-D general complex Hamiltonians. Examples are presented for Hamiltonians with πT symmetry (π:x↔y, p x ↔p y ) and the reality of these systems are investigated.

Last year our government established a regulation for the Radioactive Waste Management ('RWM') Fund. This regulation had two principal items - establishment of the RWM Fund and organization of a public corporation. This regulation will promote transparency, fairness, and safety of the RWM Project. There is strong interest between current generations and future descendants for the RWM Project. That is why the project will continue for a long period of time whereas, the public is currently benefiting from the nuclear electricity. Radioactive waste is a by-product that is inevitably produced as long as the nuclear power plant generates the electricity. This article focuses on calculating a reasonable fee for the RWM Fund in order to minimize conflicts between generations and to fairly share the burden

The asynchronous event distribution system (AEDS) was built to provide synchronization resources within the TJ-II local area network. It is a software system developed to add 'soft synchronization' capabilities to the TJ-II data acquisition, control and analysis environments. 'Soft synchronization' signifies that AEDS is not a real-time system. In fact, AEDS is based on TCP/IP over ETHERNET networks. However, its response time is adequate for practical purposes when synchronization requirements can support some delay between event dispatch and message reception. Event broadcasters (or synchronization servers in AEDS terminology) are Windows computers. Destination computers (or synchronization clients) were also Windows machines in the first version of AEDS. However, this fact imposed a very important limitation on synchronization capabilities. To overcome this situation, synchronization clients for different environments have been added to AEDS: for time-sharing operating systems (Unix and Linux), real-time operating systems (OS-9 and VxWorks) and Java applications. These environments have different synchronization primitives, requiring different approaches to provide the required uniform functionality. This has been achieved with POSIX thread library synchronization primitives (mutex and condition variables) on Unix/Linux systems, IPC mechanisms for concurrent processes on OS-9 and VxWorks real-time operating systems, and 'synchronized-wait/notify' primitives on Java virtual machines.

Perceptions of Time and Long Time Intervals

There are certainly many perspectives presented in the literature on time and time perception. This contribution has focused on perceptions of the time frames related to risk and danger of radiation from a planned Swedish repository for spent nuclear fuel. Respondents from two municipalities judged SSI's reviews of the entrepreneur's plans and work of high importance, and more important the closer to our time the estimate was given. Similarly were the consequences of potential leakage from a repository perceived as more serious the closer it would be to our time. Judgements of risks related to the storage of spent nuclear fuel were moderately large on the used measurement scales. Experts are experts because they have more knowledge, and in this context they underlined e.g. the importance of reviews of the radiation situation of time periods up to 100,000 years. It was of interest to note that 55% of the respondents from the municipalities did not believe that the future repository would leak radioactivity. They were much more pessimistic with respect to world politics, i.e. a new world war. However, with respect to the seriousness of the consequences given a leakage from the repository, the public group consistently gave high risk estimates, often significantly higher than those of the expert group. The underestimations of time estimates, as seen in the tasks of pinpointing historic events, provide examples of the difficulty of making estimations involving long times. Similar results showed that thinking of 'the future' most often involved about 30 years. On average, people reported memories of about 2.5 generations back in time, and emotional relationships stretching approximately 2.5 generations into the future; 94% of the responses, with respect to how many future generations one had an emotional relationship, were given in the range of 1-5 generations. Similarly, Svenson and Nilsson found the opinion that the current generations' general responsibility for

Influence of sintering time on distribution of alloying elements composition in zircaloy pellet has been studied. Zircaloy pellets were obtained by pressing of Zr, Fe, Cr and Sn powders mixture in adequate composition of zircaloy-4, than the green pellets were sintered at 1100 o C for 1 - 3 hours. The alloying elements (Fe, Cr and Sn) composition in zircaloy pellets as sintering product were determined by Scanning Electron Microscope - Energy Dispersive X-Ray Analyser (SEM-EDAX). The experiments showed that there was an accumulation of Sn in a site of the zircaloy green pellet of 17.46 %, but after sintering process, the Sn was distributed everywhere. The influence of sintering time up to 1 hour showed a decreasing Sn composition from 9 % to 2 % which then relatively constant, while for Fe and Cr its decreasing was relatively small, i.e. : 1.86 % to 0.6 % and 1.04 % to 0.17 % respectively. The sintering process revealed no clear grain boundaries and powder homogenization did not complete. Observation on metallographic photos showed that this condition was in initial stage of sintering process where there was a complex phenomenon i.e.: no powder homogenization in green pellet or initial heating rate was extremely quick

Abstract A RAND team conducted an independent implementation evaluation of the Re-Engineering Systems of Primary Care Treatment in the Military (RESPECT-Mil) Program, a system of care designed to screen, assess, and treat posttraumatic stress disorder and depression among active duty service members in the Army's primary care settings. Evaluating the Implementation of the Re-Engineering Systems of Primary Care Treatment in the Military (RESPECT-Mil) presents the results from RAND's assessment of the implementation of RESPECT-Mil in military treatment facilities and makes recommendations to improve the delivery of mental health care in these settings. Analyses were based on existing program data used to monitor fidelity to RESPECT-Mil across the Army's primary care clinics, as well as discussions with key stakeholders. During the time of the evaluation, efforts were under way to implement the Patient Centered Medical Home, and uncertainties remained about the implications for the RESPECT-Mil program. Consideration of this transition was made in designing the evaluation and applying its findings more broadly to the implementation of collaborative care within military primary care settings.

Generic drugs are equivalent to the brand formulation if they have the same active substance, the same pharmaceutical form and the same therapeutic indications and a similar bioequivalence respect to the reference medicinal product. The use of generic drugs is indicated from many countries in order to reduce medication price. However some points, such as bioequivalence and the role of excipients, may be clarified regarding the clinical efficacy and safety during the switch from brand to generic formulations. In conclusion, the use of generic drugs could be related with an increased days of disease (time to relapse) or might lead to a therapeutic failure; on the other hand, a higher drug concentration might expose patients to an increased risk of dose-dependent side-effects.

Time series prediction: statistical and neural techniques

Zahirniak, Daniel R.; DeSimio, Martin P.

1996-03-01

In this paper we compare the performance of nonlinear neural network techniques to those of linear filtering techniques in the prediction of time series. Specifically, we compare the results of using the nonlinear systems, known as multilayer perceptron and radial basis function neural networks, with the results obtained using the conventional linear Wiener filter, Kalman filter and Widrow-Hoff adaptive filter in predicting future values of stationary and non- stationary time series. Our results indicate the performance of each type of system is heavily dependent upon the form of the time series being predicted and the size of the system used. In particular, the linear filters perform adequately for linear or near linear processes while the nonlinear systems perform better for nonlinear processes. Since the linear systems take much less time to be developed, they should be tried prior to using the nonlinear systems when the linearity properties of the time series process are unknown.

Colon preparation for a colonoscopy in children is a difficult task because of the unpalatable taste and large volume of cleansing solution that needs to be consumed to ensure a clean colon. Consequently, an unprepared colon frequently occurs in routine practices, which causes early termination and a repeated procedure. (1) To assess the effectiveness of polyethylene glycol solution (PEG 3350) in preparing the colon of children scheduled for a colonoscopy and (2) to investigate clinical markers associated with an adequate colon preparation before a colonoscopy. A total of 167 children scheduled for a colonoscopy. In a prospective study, children scheduled for a colonoscopy were given PEG 3350 solution (1.5 g/kg per day, up to 100 g/d) over a 4-day preparation period. Each day, a simple questionnaire that documents the amount of liquid consumed, adverse effects, and the number and consistency of stool was completed by the parents. After a colonoscopy procedure, the colon preparation was assigned a number grade. The data were later assessed and were compared to determine the association between the grade of cleansing and the frequency and/or consistency of stool during preparation. Colon preparation was completed in 149 children, 133 of whom were adequately prepared. Inadequate preparation was found in 16 children; the procedure was terminated prematurely in 2 of these patients because of unacceptable conditions. No significant adverse effects were noted. A number of >or=5 stools/d, and liquid stool consistency in the last 2 days of preparation were associated with adequate colon preparation. PEG 3350 solution is safe, efficacious, and tolerable for children. Stool frequency and consistency in the last 2 days of preparation were excellent markers (positive predictive value 91%-95%), which predict an adequately clean colon before a colonoscopy in children.

The majority of Ugandan children face vulnerability and malnutrition. As a State Party to international human rights treaties, Uganda has legal obligations of guaranteeing the fundamental rights and the best interest of the nation's children. Despite being protected under international and national law, Uganda is not providing adequate child protection, including safeguarding children's food security. Numerous privately owned and unregulated children's homes face this problem. The overall aim of the study was to examine to what extent children's homes' operations are consistent with the right to adequate food, nutritional health and wellbeing of children. We performed a qualitative role- and capacity analysis of duty bearers with human rights duties towards children living in children's homes. We studied three groups of duty bearers: caretakers working in private children's homes, State actors working in government and its institutions, and non-State actors working in civil society organizations. A human rights based approach guided all aspects of the study. An analysis of the roles, performance and capacities of duty bearers was employed, with individual face-to-face structured qualitative in-depth interviews, self-administered structured questionnaires, and a structured observational study, as well as a desk review of relevant literature. The State of Uganda's efforts to respect and realize its obligations towards children living in children's homes is inadequate. There are numerous capacity gaps among the duty bearers, and the concepts of human rights and the best interest of the child are not well understood among the duty bearers. The efforts of the State of Uganda to realize its human rights obligations towards children in children's homes are lacking in important areas. Hence the State does not fulfill its minimum obligations under the International Covenant on Economic, Social and Cultural Rights to ensure all children freedom from hunger. There is a need

According to several studies, infants whose mothers had a malaria-infected placenta (MIP) at delivery are at increased risk of a first malaria infection. Immune tolerance caused by intrauterine contact with the parasite could explain this phenomenon, but it is also known that infants who are highly exposed to Anopheles mosquitoes infected with Plasmodium are at greater risk of contracting malaria. Consequently, local malaria transmission must be taken into account to demonstrate the immune tolerance hypothesis. From data collected between 2007 and 2010 on 545 infants followed from birth to age 18 months in southern Benin, we compared estimates of the effect of MIP on time to first malaria infection obtained through different Cox models. In these models, MIP was adjusted for either 1) "village-like" time-independent exposure variables or 2) spatiotemporal exposure prediction derived from local climatic, environmental, and behavioral factors. Only the use of exposure prediction improved the model's goodness of fit (Bayesian Information Criterion) and led to clear conclusions regarding the effect of placental infection, whereas the models using the village-like variables were less successful than the univariate model. This demonstrated clearly the benefit of adequately taking transmission into account in cohort studies of malaria.

Basing Science Ethics on Respect for Human Dignity.

Science.gov (United States)

Aközer, Mehmet; Aközer, Emel

2016-12-01

A "no ethics" principle has long been prevalent in science and has demotivated deliberation on scientific ethics. This paper argues the following: (1) An understanding of a scientific "ethos" based on actual "value preferences" and "value repugnances" prevalent in the scientific community permits and demands critical accounts of the "no ethics" principle in science. (2) The roots of this principle may be traced to a repugnance of human dignity, which was instilled at a historical breaking point in the interrelation between science and ethics. This breaking point involved granting science the exclusive mandate to pass judgment on the life worth living. (3) By contrast, respect for human dignity, in its Kantian definition as "the absolute inner worth of being human," should be adopted as the basis to ground science ethics. (4) The pathway from this foundation to the articulation of an ethical duty specific to scientific practice, i.e., respect for objective truth, is charted by Karl Popper's discussion of the ethical principles that form the basis of science. This also permits an integrated account of the "external" and "internal" ethical problems in science. (5) Principles of the respect for human dignity and the respect for objective truth are also safeguards of epistemic integrity. Plain defiance of human dignity by genetic determinism has compromised integrity of claims to knowledge in behavioral genetics and other behavioral sciences. Disregard of the ethical principles that form the basis of science threatens epistemic integrity.

2017-01-01

Objectives: The aim of this study was to determine the respective contribution of professional characteristics, team attributes, team processes, and team emergent states on the job satisfaction of 315 mental health professionals from Quebec (Canada). Methods: Job satisfaction was measured with the Job Satisfaction Survey. Independent variables were organized into four categories according to a conceptual framework inspired from the Input-Mediator-Outcomes-Input Model. The contribution of each category of variables was assessed using hierarchical regression analysis. Results: Variations in job satisfaction were mostly explained by team processes, with minimal contribution from the other three categories. Among the six variables significantly associated with job satisfaction in the final model, four were team processes: stronger team support, less team conflict, deeper involvement in the decision-making process, and more team collaboration. Job satisfaction was also associated with nursing and, marginally, male gender (professional characteristics) as well as with a stronger affective commitment toward the team (team emergent states). Discussion and Conclusion: Results confirm the importance for health managers of offering adequate support to mental health professionals, and creating an environment favorable to collaboration and decision-sharing, and likely to reduce conflicts between team members.

“Patient-Time,” “Doctor-Time,” and “Institution-Time”: Perceptions and Definitions of Time Among Doctors Who Become Patients

Klitzman, Robert

2010-01-01

Objective To examine views and experiences of conflicts concerning time in healthcare, from the perspective of physicians who have become patients. Methods We conducted two in-depth semi-structured two-hour interviews concerning experiences of being health care workers, and becoming a patient, with each of 50 doctors who had serious illnesses. Results These doctor-patients often came to realize as they had not before how patients experience time differently, and how “patient-time,” “doctor-time,” and “institution-time” exist and can conflict. Differences arose in both long and short term, regarding historical time (prior eras/decades in medicine), prognosis (months/years), scheduling delays (days/weeks), daily medical events and tasks (hours), and periods in waiting rooms (minutes/hours). Definitions of periods of time (e.g., “fast,” “slow,” “plenty,” and “soon”) also varied widely, and could clash. Professional socialization had heretofore impeded awareness of these differences. Physicians tried to address these conflicts in several ways (e.g., trying to provide test results promptly), though full resolution remained difficult. Conclusions Doctors who became patients often now realized how physicians and patients differ in subjective experiences of time. Medical education and research have not adequately considered these issues, which can affect patient satisfaction, doctor-patient relationships and communication, and care. Practice Implications Physicians need to be more sensitive to how their definitions, perceptions, and experiences concerning time can differ from those of patients. PMID:17125956

Full Text Available OBJECTIVE: Applications of resin luting agents and high-power light-emitting diodes (LED light-curing units (LCUs have increased considerably over the last few years. However, it is not clear whether the effect of reduced exposure time on cytotoxicity of such products have adequate biocompatibility to meet clinical success. This study aimed at assessing the effect of reduced curing time of five resin luting cements (RLCs polymerized by high-power LED curing unit on the viability of a cell of L-929 fibroblast cells. MATERIAL AND METHODS: Disc-shaped samples were prepared in polytetrafluoroethylene moulds with cylindrical cavities. The samples were irradiated from the top through the ceramic discs and acetate strips using LED LCU for 20 s (50% of the manufacturer's recommended exposure time and 40 s (100% exposure time. After curing, the samples were transferred into a culture medium for 24 h. The eluates were obtained and pipetted onto L-929 fibroblast cultures (3x10(4 per well and incubated for evaluating after 24 h. Measurements were performed by dimethylthiazol diphenyltetrazolium assay. Statistical significance was determined by two-way ANOVA and two independent samples were compared by t-test. RESULTS: Results showed that eluates of most of the materials polymerized for 20 s (except Rely X Unicem and Illusion reduced to a higher extent cell viability compared to samples of the same materials polymerized for 40 s. Illusion exhibited the least cytotoxicity for 20 s exposure time compared to the control (culture without samples followed by Rely X Unicem and Rely X ARC (90.81%, 88.90%, and 83.11%, respectively. For Rely X ARC, Duolink and Lute-It 40 s exposure time was better (t=-1.262 p=0,276; t=-9.399 p=0.001; and t=-20.418 p<0.001, respectively. CONCLUSION: The results of this study suggest that reduction of curing time significantly enhances the cytotoxicity of the studied resin cement materials, therefore compromising their clinical

Humility and respect: core values in medical education.

Science.gov (United States)

Gruppen, Larry D

2014-01-01

Many of the values and behaviours described in the original Hippocratic Oath are relevant to medical education. In particular, the values of intellectual humility and respect for one's colleagues are essential in all scientific disciplines. There are three contexts within medical education from which to consider humility and respect: uncertainty; theory, and colleagues. As medical education grows in scope and participation, we will be required to acknowledge that we 'know not' with increasing frequency. The uncertainty of what we do and do not know is compounded by uncertainty about whether ignorance is individual or corporate. As difficult as it is to admit that we 'know not', it is dangerous NOT to recognise the limits of our knowledge and experience. Theories are critical tools in understanding complex phenomena. They identify constructs and relationships that are important and those that are irrelevant. We tend to forget that theories are models or simplified representations of reality and not in themselves 'truths'. Viewing problems from other theoretical perspectives can widen our horizons by allowing us to identify possibly important concepts and relationships that we have not considered. Colleagues are invaluable for helping us respond to our 'knowing not' and for providing alternative perspectives when our theories lead us astray. However, colleagues come in many guises and include close colleagues, as well as those in distant fields. As obviously desirable as humility and respect seem to be, there are conflicts that prevent us from being humble and respectful. Such conflicts include other salient professional values, such as critical scepticism, competition and confidence. Adoption of the values of humility and respect in medical education can be fostered through intentional behaviours, both as individuals and as a discipline. We can deliberately seek to broaden our horizons to promote intellectual humility. We can foster collaboration among colleagues

Perceptions of Time and Long Time Intervals

There are certainly many perspectives presented in the literature on time and time perception. This contribution has focused on perceptions of the time frames related to risk and danger of radiation from a planned Swedish repository for spent nuclear fuel. Respondents from two municipalities judged SSI's reviews of the entrepreneur's plans and work of high importance, and more important the closer to our time the estimate was given. Similarly were the consequences of potential leakage from a repository perceived as more serious the closer it would be to our time. Judgements of risks related to the storage of spent nuclear fuel were moderately large on the used measurement scales. Experts are experts because they have more knowledge, and in this context they underlined e.g. the importance of reviews of the radiation situation of time periods up to 100,000 years. It was of interest to note that 55% of the respondents from the municipalities did not believe that the future repository would leak radioactivity. They were much more pessimistic with respect to world politics, i.e. a new world war. However, with respect to the seriousness of the consequences given a leakage from the repository, the public group consistently gave high risk estimates, often significantly higher than those of the expert group. The underestimations of time estimates, as seen in the tasks of pinpointing historic events, provide examples of the difficulty of making estimations involving long times. Similar results showed that thinking of 'the future' most often involved about 30 years. On average, people reported memories of about 2.5 generations back in time, and emotional relationships stretching approximately 2.5 generations into the future; 94% of the responses, with respect to how many future generations one had an emotional relationship, were given in the range of 1-5 generations. Similarly, Svenson and Nilsson found the opinion that the current generations

Atmospheric corrosion products in copper samples, known as patinas, formed in industrial-marine, severe-marine and rural atmospheres exposed for 1,2,3, and 4 years, have been studied. The nature and structure of the products formed, characterized by X-ray diffraction (XRD) and infrared spectrometry (FTIR) depend on the time of exposure and the type of atmosphere. Copper patinas have been extensively mentioned in the literature, but the structural nature of their compounds, which vary according to the time of exposure and types of atmospheres, is still not adequately described in the literature. In order to give a contribution to this area, copper panels were exposed for 1,2,3, and 4 years in different types of atmospheres representing situations commonly observed, and subsequently the patinas were studied by XRD and FTIR 150 mm x 1 mm copper panels from commercial copper were exposed to three different atmospheric conditions in Portugal: industrial-marine (Leixoes, near Oporto, highly industrialized city close to the Ocean, subject to SO 2 from refineries); rural (Pego, small village in rural environment). The panels, attached to the appropriate stands, in accordance with ISO 8565 (1), were exposed for periods of 1,2,3 and 4 years, adequately collected for laboratory analysis by infrared spectrometry (FTIR).

To examine potential cost savings from decreased adverse resident outcomes versus additional wages of nurses when nursing homes have adequate staffing. A retrospective cost study using differences in adverse outcome rates of pressure ulcers (PUs), urinary tract infections (UTIs), and hospitalizations per resident per day from low staffing and adequate staffing nursing homes. Cost savings from reductions in these events are calculated in dollars and compared with costs of increasing nurse staffing. Eighty-two nursing homes throughout the United States. One thousand three hundred seventy-six frail elderly long-term care residents at risk of PU development. Event rates are from the National Pressure Ulcer Long-Term Care Study. Hospital costs are estimated from Medicare statistics and from charges in the Healthcare Cost and Utilization Project. UTI costs and PU costs are from cost-identification studies. Time horizon is 1 year; perspectives are societal and institutional. Analyses showed an annual net societal benefit of 3,191 dollars per resident per year in a high-risk, long-stay nursing home unit that employs sufficient nurses to achieve 30 to 40 minutes of registered nurse direct care time per resident per day versus nursing homes that have nursing time of less than 10 minutes. Sensitivity analyses revealed a robust set of estimates, with no single or paired elements reaching the cost/benefit equality threshold. Increasing nurse staffing in nursing homes may create significant societal cost savings from reduction in adverse outcomes. Challenges in increasing nurse staffing are discussed.

Systolic time intervals are highly correlated to fundamental cardiac functions. Several studies have shown that these measurements have significant diagnostic and prognostic value in heart failure condition and are adequate for long-term patient follow-up and disease management. In this paper, we investigate the feasibility of using heart sound (HS) to accurately measure the opening and closing moments of the aortic heart valve. These moments are crucial to define the main systolic timings of the heart cycle, i.e. pre-ejection period (PEP) and left ventricular ejection time (LVET). We introduce an algorithm for automatic extraction of PEP and LVET using HS and electrocardiogram. PEP is estimated with a Bayesian approach using the signal's instantaneous amplitude and patient-specific time intervals between atrio-ventricular valve closure and aortic valve opening. As for LVET, since the aortic valve closure corresponds to the start of the S2 HS component, we base LVET estimation on the detection of the S2 onset. A comparative assessment of the main systolic time intervals is performed using synchronous signal acquisitions of the current gold standard in cardiac time-interval measurement, i.e. echocardiography, and HS. The algorithms were evaluated on a healthy population, as well as on a group of subjects with different cardiovascular diseases (CVD). In the healthy group, from a set of 942 heartbeats, the proposed algorithm achieved 7.66 ± 5.92 ms absolute PEP estimation error. For LVET, the absolute estimation error was 11.39 ± 8.98 ms. For the CVD population, 404 beats were used, leading to 11.86 ± 8.30 and 17.51 ± 17.21 ms absolute PEP and LVET errors, respectively. The results achieved in this study suggest that HS can be used to accurately estimate LVET and PEP. (paper)

Diabetes guidelines may delay timely adjustments during treatment and might contribute to clinical inertia.

Clinical inertia and poor knowledge by many physicians play an important role in delaying diabetes control. Among other guidelines, the Position Statement of the American Diabetes Association/European Association for the Study of Diabetes on Management of Hyperglycemia in Type 2 Diabetes is a respected guideline with high impact on this subject in terms of influencing physicians in the definition of strategic approach to overcome poor glycemic control. But, on the other hand, it carries a recommendation that might contribute to clinical inertia because it can delay the needed implementation of more vigorous, intensive, and effective strategies to overcome poor glycemic control within a reasonable time frame during the evolution of the disease. The same is true with other respected algorithms from different diabetes associations. Together with pharmacological interventions, diabetes education and more intensive blood glucose monitoring in the initial phases after the diagnosis are key strategies for the effective control of diabetes. The main reason why a faster glycemic control should be implemented in an effective and safe way is to boost the confidence and the compliance of the patient to the recommendations of the diabetes care team. Better and faster results in glycemic control can only be safely achieved with educational strategies, structured self-monitoring of blood glucose, and adequate pharmacological therapy in the majority of cases.

Contempt as the absence of appraisal, not recognition, respect.

2017-01-01

Gervais & Fessler's defense of a sentiment construct for contempt captures features distinguishing the phenomenon from basic emotions and highlights the fact that it comprises a coordinated syndrome of responses. However, their conceptualization of contempt as the absence of respect equivocates. Consequently, a "dignity" culture that prescribes respect does not thereby limit legitimate contempt in the manner the authors claim.

Full Text Available In non-ideal scenarios involving partial or non-breastfeeding, cow’s milk-based dairy products are mainstream in infant feeding. Therefore, it is important to study the concentrations of potentially neurotoxic contaminants (Pb and Cd and their respective counteracting elements (Ca and Zn in infant dairy products. Fifty-five brands of infant formulas and milk sold in Brasilia, Brazil were analyzed. The dairy products came from areas in the central-west (26%, southeast (29% and south of Brazil (36% extending as far as Argentina (7% and the Netherlands (2%. For toxic Pb and Cd, median concentrations in powdered samples were 0.109 mg/kg and 0.033 mg/kg, respectively; in fluid samples median Pb concentration was 0.084 mg/kg, but median Cd concentration was below the limit of detection and overall values were below reference safety levels. However, 62% of these samples presented higher Pb concentration values than those established by FAO/WHO. Although the inverse correlation between Cd and Zn (Spearman r = −0.116; P = 0.590 was not statistically significant, the positive correlation between Ca and Pb was (Spearman r = 0.619; P < 0.0001. Additionally, there was a significant correlation between Pb and Cd. Furthermore, the study also revealed that provision of the essential trace element Zn in infant formulas can provide adequate amounts of the recommended daily requirements. Infant formulas and milk sold for consumption by infants and children can be an efficient tool to monitor neurotoxic metal risk exposure among young children.

Real-time data collection in Linux: a case study.

Science.gov (United States)

Finney, S A

2001-05-01

Multiuser UNIX-like operating systems such as Linux are often considered unsuitable for real-time data collection because of the potential for indeterminate timing latencies resulting from preemptive scheduling. In this paper, Linux is shown to be fully adequate for precisely controlled programming with millisecond resolution or better. The Linux system calls that subserve such timing control are described and tested and then utilized in a MIDI-based program for tapping and music performance experiments. The timing of this program, including data input and output, is shown to be accurate at the millisecond level. This demonstrates that Linux, with proper programming, is suitable for real-time experiment software. In addition, the detailed description and test of both the operating system facilities and the application program itself may serve as a model for publicly documenting programming methods and software performance on other operating systems.

On Space-Time Resolution of Inflow Representations for Wind Turbine Loads Analysis

Directory of Open Access Journals (Sweden)

Lance Manuel

2012-06-01

Full Text Available Efficient spatial and temporal resolution of simulated inflow wind fields is important in order to represent wind turbine dynamics and derive load statistics for design. Using Fourier-based stochastic simulation of inflow turbulence, we first investigate loads for a utility-scale turbine in the neutral atmospheric boundary layer. Load statistics, spectra, and wavelet analysis representations for different space and time resolutions are compared. Next, large-eddy simulation (LES is employed with space-time resolutions, justified on the basis of the earlier stochastic simulations, to again derive turbine loads. Extreme and fatigue loads from the two approaches used in inflow field generation are compared. On the basis of simulation studies carried out for three different wind speeds in the turbine’s operating range, it is shown that inflow turbulence described using 10-meter spatial resolution and 1 Hz temporal resolution is adequate for assessing turbine loads. Such studies on the investigation of adequate filtering or resolution of inflow wind fields help to establish efficient strategies for LES and other physical or stochastic simulation needed in turbine loads studies.

Guaranteed cost control of time-delay chaotic systems

This article studies a guaranteed cost control problem for a class of time-delay chaotic systems. Attention is focused on the design of memory state feedback controllers such that the resulting closed-loop system is asymptotically stable and an adequate level of performance is also guaranteed. Using the Lyapunov method and LMI (linear matrix inequality) framework, two criteria for the existence of the controller are derived in terms of LMIs. A numerical example is given to illustrate the proposed method

Background: Diabetes mellitus affects more than 285 million people worldwide. The prevalence is expected to rise to 439 million by the year 2030. Diabetic foot ulcers precede 84 percentage of non-traumatic amputations in diabetics. One lower limb is lost every 30 seconds around the world because of diabetic foot ulceration. Apart from being lengthy, the treatment of diabetic foot is also very expensive. There is very limited emphasis on foot care in diabetic patients. Even in developed countries patients feel that they do not have adequate knowledge about foot care. This study was conducted to find out how much information is imparted by doctors to diabetic patients about foot care. Methods: This cross-sectional study was conducted in admitted patients of the Department of Medicine, DHQ Hospital, Abbottabad from May 2014 to June 2015. 139 diabetic patients more than 25 years of age were included by non-probability consecutive sampling. Results: The mean age was 57.17 ( percentage 11.1) years. 35.3 percentage of patients were male and 64.7 percentage were female. The mean duration of diabetes in patients was 8.3 (±6) years. Only 36.7 percentage of patients said that their doctor told them about foot care. Less than 40 percentage of patients knew that they should daily inspect their feet, wash them with gentle warm water, and dry them afterwards. Only 25.2 percentage of the participants knew how to manage corns or calluses on feet. 66.5 percentage of patients knew that they should not walk bare foot. Overall, 63 percentage of our patients had less than 50 percentage knowledge of the 11 points regarding foot care that the investigators asked them. Conclusion: Diabetic foot problems are the one of the costliest, most disabling and disheartening complication of diabetes mellitus. Doctors are not properly telling diabetic patients about foot care. There is a deficiency of knowledge among the diabetic patients regarding foot care. (author)

The Oncology Centre of Auckland Hospital recently purchased a Varian PortalVision TM electronic portal imaging device (EPID). Image acquisition times, input-output characteristics and contrast-detail curves of this matrix liquid ion-chamber EPID have been measured to examine the variation in imaging performance with acquisition mode. The variation in detector performance with acquisition mode has been examined. The HV cycle time can be increased to improve image quality. Consideration should be given to the acquisition mode and HV cycle time used when imaging to ensure adequate imaging performance with reasonable imaging time. (author)

Wagner, Jonas; Binkowski, Eva; Bronsart, Robert

2014-06-01

In this paper the scenario based optimization of the bulbous bow of the KRISO Container Ship (KCS) is presented. The optimization of the parametrically modeled vessel is based on a statistically developed operational profile generated from noon-to-noon reports of a comparable 3600 TEU container vessel and specific development functions representing the growth of global economy during the vessels service time. In order to consider uncertainties, statistical fluctuations are added. An analysis of these data lead to a number of most probable upcoming operating conditions (OC) the vessel will stay in the future. According to their respective likeliness an objective function for the evaluation of the optimal design variant of the vessel is derived and implemented within the parametrical optimization workbench FRIENDSHIP Framework. In the following this evaluation is done with respect to vessel's calculated effective power based on the usage of potential flow code. The evaluation shows, that the usage of scenarios within the optimization process has a strong influence on the hull form.

Loving, Brian L.; Putnam, James E.; Turk, Donita M.

2014-01-01

Continuous real-time information on streams, lakes, and groundwater is an important Kansas resource that can safeguard lives and property, and ensure adequate water resources for a healthy State economy. The U.S. Geological Survey (USGS) operates approximately 230 water-monitoring stations at Kansas streams, lakes, and groundwater sites. Most of these stations are funded cooperatively in partnerships with local, tribal, State, or other Federal agencies. The USGS real-time water-monitoring network provides long-term, accurate, and objective information that meets the needs of many customers. Whether the customer is a water-management or water-quality agency, an emergency planner, a power or navigational official, a farmer, a canoeist, or a fisherman, all can benefit from the continuous real-time water information gathered by the USGS.

The Advanced Heavy water Reactor (AHWR) is a natural circulation vertical pressure tube type boiling light water cooled and heavy water moderated reactor. As the AHWR fuel bundle quenching under accident condition is designed primarily with radial jets at several axial locations, bottom re-flooding still remain open as another option. Radial direction injection of emergency core cooling leads to rewetting of AHWR fuel cluster in circumferential direction. A 3D fuel pin model has been developed by using Finite Difference Method (FDM) of transient heat conduction equation. Alternating Direction Implicit technique of Finite Difference Method (FDM) has been used for discretisation of numerical equation in different time step at different direction. Sensitivity numerical study with respect to direction of ADI method has been carried out to optimize the time step during the transient as well as steady state and is found that it is insensitivity with direction of solution. Further, to assess influence of circumferential rewetting vis-a-vis axial rewetting. Both the analyses are carried out with same fluid temperature and heat transfer coefficients as boundary conditions. It has been found from the analyses that for radial jet, the circumferential conduction is significant and overall the fuel temperature falls in the quench plane with the initiation of quenching event. The paper discusses the sensitivity study with respect to direction of ADI solution and comparison of numerical results for circumferential and axial rewetting for single pin.

Interval timing under a behavioral microscope: Dissociating motivational and timing processes in fixed-interval performance.

Daniels, Carter W; Sanabria, Federico

2017-03-01

The distribution of latencies and interresponse times (IRTs) of rats was compared between two fixed-interval (FI) schedules of food reinforcement (FI 30 s and FI 90 s), and between two levels of food deprivation. Computational modeling revealed that latencies and IRTs were well described by mixture probability distributions embodying two-state Markov chains. Analysis of these models revealed that only a subset of latencies is sensitive to the periodicity of reinforcement, and prefeeding only reduces the size of this subset. The distribution of IRTs suggests that behavior in FI schedules is organized in bouts that lengthen and ramp up in frequency with proximity to reinforcement. Prefeeding slowed down the lengthening of bouts and increased the time between bouts. When concatenated, latency and IRT models adequately reproduced sigmoidal FI response functions. These findings suggest that behavior in FI schedules fluctuates in and out of schedule control; an account of such fluctuation suggests that timing and motivation are dissociable components of FI performance. These mixture-distribution models also provide novel insights on the motivational, associative, and timing processes expressed in FI performance. These processes may be obscured, however, when performance in timing tasks is analyzed in terms of mean response rates.

Teachers are a key part of the wider public health workforce in England. We conducted a survey to find out how they are trained for this role during their initial teacher education (ITE). Between 2011 and 2012, we sent an online questionnaire to 220 ITE course managers and conducted semi-structured interviews with a purposive sample of 19 course managers to explore issues in more depth. The response rate to the questionnaire was 34% (n = 74). Although most of the course managers felt inclusion of health and well-being training in ITE was important, provision across courses was variable. Topics which are public health priorities [e.g. sex and relationships education (SRE) and drugs, alcohol and tobacco] were covered by fewer courses than other topics (e.g. child protection, emotional health and anti-bullying). Perceived barriers to training included lack of time and a belief that health and well-being were low priorities in educational policy. Not all of tomorrow's teachers are being adequately prepared for their role in helping to address public health priorities. Educational policy does not appear to be supporting the priorities of public health policy, and this is a key barrier to health promotion training in ITE.

Revisiting Respect for Persons in Genomic Research

Directory of Open Access Journals (Sweden)

Debra J. H. Mathews

2014-01-01

Full Text Available The risks and benefits of research using large databases of personal information are evolving in an era of ubiquitous, internet-based data exchange. In addition, information technology has facilitated a shift in the relationship between individuals and their personal data, enabling increased individual control over how (and how much personal data are used in research, and by whom. This shift in control has created new opportunities to engage members of the public as partners in the research enterprise on more equal and transparent terms. Here, we consider how some of the technological advances driving and paralleling developments in genomics can also be used to supplement the practice of informed consent with other strategies to ensure that the research process as a whole honors the notion of respect for persons upon which human research subjects protections are premised. Further, we suggest that technological advances can help the research enterprise achieve a more thoroughgoing respect for persons than was possible when current policies governing human subject research were developed. Questions remain about the best way to revise policy to accommodate these changes.

The Comprehension Problems of Children with Poor Reading Comprehension despite Adequate Decoding: A Meta-Analysis.

Science.gov (United States)

Spencer, Mercedes; Wagner, Richard K

2018-06-01

The purpose of this meta-analysis was to examine the comprehension problems of children who have a specific reading comprehension deficit (SCD), which is characterized by poor reading comprehension despite adequate decoding. The meta-analysis included 86 studies of children with SCD who were assessed in reading comprehension and oral language (vocabulary, listening comprehension, storytelling ability, and semantic and syntactic knowledge). Results indicated that children with SCD had deficits in oral language ( d = -0.78, 95% CI [-0.89, -0.68], but these deficits were not as severe as their deficit in reading comprehension ( d = -2.78, 95% CI [-3.01, -2.54]). When compared to reading comprehension age-matched normal readers, the oral language skills of the two groups were comparable ( d = 0.32, 95% CI [-0.49, 1.14]), which suggests that the oral language weaknesses of children with SCD represent a developmental delay rather than developmental deviance. Theoretical and practical implications of these findings are discussed.

A programme to reduce down-time and site radiation dose through improvements in control rod design

International Nuclear Information System (INIS)

Izatt, J.A.; Scobie, J.

1983-01-01

In many nuclear facilities a high proportion of the total radiation dose to staff may be ascribed to very few routine operations. Often this critical operation will require significant shut-down time, both to perform the function itself and to allow sufficient decay time to reduce radiation levels to acceptable values. This situation arises on the UTR-300 reactor at S.U.R.R.C., where over the twenty years of operation it has been found necessary to carry out preventive, and on some occasions remedial, maintenance at least once per year on the in-core elements of the control rod assemblies. This had led inevitably to reduced availability of the reactor and to significant overall radiation doses to the few long-serving staff members who carry out this work. The source of the problem seems to lie in the basic design of the assemblies, which may have been adequate for the original 10 KW versions of this reactor, but has proven to be deficient in several respects at the present 300 KW operating level. In an attempt to reduce down-time and radiation dose to staff a radical re-design of the control assemblies was undertaken in-house, and a conversion programme has been underway over the last two years. Details of the design improvements are presented with a discussion of the operating experience to date. (author)

Similarity solutions of time-dependent relativistic radiation-hydrodynamical plane-parallel flows

2018-04-01

Similarity solutions are examined for the frequency-integrated relativistic radiation-hydrodynamical flows, which are described by the comoving quantities. The flows are vertical plane-parallel time-dependent ones with a gray opacity coefficient. For adequate boundary conditions, the flows are accelerated in a somewhat homologous manner, but terminate at some singular locus, which originates from the pathological behavior in relativistic radiation moment equations truncated in finite orders.

Respecting the Aging Self: Communication in the Nursing Home

Directory of Open Access Journals (Sweden)

Jean Tinney

2015-06-01

Full Text Available This article draws on findings of an ethnographic nursing home study that explores the role of communication in maintaining residents’ sense of self. These findings suggest that the nursing home can be a site for recovery for the aging self, despite loss and bereavement and the negative effects on self-esteem of pain, illness and loss of function. However, where care privileges the body over social and emotional needs, residents have inadequate opportunities for communication essential to make sense of being old and in care. The key to sustaining the aging self is empathetic communication that recognizes the individuality and value of each older person, no matter how reduced by present illness or incapacity, and at the same time respects residents’ rights of choice and personal control. Harried staff, often well-intentioned but unsupported by management, carry an unfair burden. Frequently called upon to do more with less, they find themselves faced with the competing pressures of work routines and residents’ emotional needs. In trying to balance these competing needs and provide opportunities for residents to exert personal control over their lives, they must protect both the residents and themselves from the results of “wrong” choices.

Discussion: More than 50% of incident HD patients with RKF have adequate kidney urea clearance to be considered for 2-times weekly HD. When additionally ultrafiltration volume and blood pressure stability are taken into account, more than one-fourth of the total cohort could optimally start HD in an incremental fashion.

Time orientation, planning horizons and responsibility into the future

Subjects of four categories (social science students, engineering students, retired people and nuclear waste experts) were asked about past events, planning, risks and future time with emphasis on energy related issues and in particular questions concerning spent nuclear waste. Among, the results reported it was found that events in the past were located more or less correctly and that events further back systematically too close to the present. Today's responsibility into the future was judged to cover 3 to 6 generations ahead and an adequate planning horizon for a local community to be on the average 11 to 14 years. Adequate planning horizons for the handling of spent nuclear fuel were judged to be from 100 to 500 years. The responsibility for effects of today's decisions was judged to be from about 100 to 300 years into the future for environmental pollution and from about 50 to 600 years for nuclear waste. However, non-negliqable proportions of the subjects choose a more moral standpoint and gave answers indicating that responsibility had to be unlimited. Some sex differences were found and an interaction with age offered as a hypothesis to be investigated in the future. Interrelations between clusters of questions revealed some links from past time and planning to judgements of environmental and nuclear power related risks. (orig.)

The transmission of the Mössbauer radiation through an absorber being in the acoustic oscillation mode under forward scattering (FS) conditions has been analyzed. The modification of the existing models of the FS spectra (frequency and time) formation to the case of the arbitrary phase correlation of nuclear oscillations in the sample has been proposed. An adequate description of the time delayed experiments with the {sup 57}Fe Mössbauer resonance using the modulation of the single-photon wave packet by acoustic field has been obtained. One has been done in the frame of the Raman scattering of Mössbauer photons. The models extended this way can be used to control the degree of phase correlation of nuclear oscillations (or other processes) induced in the sample by external fields.

Study of Time-Dependent Properties of Thermoplastics

Bolchoun A.

2010-06-01

Full Text Available Simple tests carried out with a common tension/compression testing machine are used to obtain timedependent properties of non-reinforced thermoplastics. These tests include ramp loadings as well as relaxation and creep tests. Two materials (PBT Celanex 2002-2 and POM Hostaform C9021, Ticona GmbH, Kelsterbach were taken for the experiments. The experiments show that an adequate description of the long-term material properties can be obtained from the short-time tests, namely from tests with constant traverse speed $L^.$. Below a model for the time-dependent mechanical behavior is presented and fitted to the obtained measured data. For the evaluation of the fitting quality long-term tests are used. Especially creep and relaxation tests with ”jumps”, i.e. rapid change of loading, are important for this purpose.

We develop a newapproach on the (1 + 3) threading of spacetime (M, g) with respect to a congruence of curves defined by an arbitrary timelike vector field. The study is based on spatial tensor fields and on theRiemannian spatial connection ∇*, which behave as 3D geometric objects. We obtain new formulas for local components of the Ricci tensor field of (M, g) with respect to the threading frame field, in terms of the Ricci tensor field of ∇* and of kinematic quantities. Also, new expressions for time covariant derivatives of kinematic quantities are stated. In particular, a new form of Raychaudhuri's equation enables us to prove Lemma 6.3, which completes a well-known lemma used in the proof of the Penrose-Hawking singularity theorems. Finally, we apply the new (1 + 3) formalism to the study of the dynamics of a Kerr-Newman black hole. (orig.)

2010-12-01

A problem faced by health professions education throughout the world is a lack of full-time clinical teachers. This is particularly serious in dentistry and nursing, but is increasingly also true in medicine. To make up for this shortfall there is a growing reliance on part-time clinical teachers. Part-time clinical teachers are essential for the education of students. However, compared with their full-time counterparts, the part-time teachers are often not adequately prepared for their roles as educators within the context of the clinical curriculum. They might not be trained in the latest educational practices, and may be unprepared for the time needed to excel as teachers and mentors. As part-time teachers take on more responsibility, it is important that they take part in orientation and training sessions to assist them in developing the skills they need to succeed. This will require a significant commitment from the institution as well as the part-time teacher, but is critical for maintaining the academic quality of the clinical training programmes. This also represents an untapped area for research into how to ensure the success of part-time clinical teachers. © Blackwell Publishing Ltd 2010.

A FRET-based real-time PCR assay to identify the main causal agents of New World tegumentary leishmaniasis.

Full Text Available In South America, various species of Leishmania are endemic and cause New World tegumentary leishmaniasis (NWTL. The correct identification of these species is critical for adequate clinical management and surveillance activities. We developed a real-time polymerase chain reaction (PCR assay and evaluated its diagnostic performance using 64 archived parasite isolates and 192 prospectively identified samples collected from individuals with suspected leishmaniasis enrolled at two reference clinics in Lima, Peru. The real-time PCR assay was able to detect a single parasite and provided unambiguous melting peaks for five Leishmania species of the Viannia subgenus that are highly prevalent in South America: L. (V. braziliensis, L. (V. panamensis, L. (V. guyanensis, L. (V. peruviana and L. (V. lainsoni. Using kinetoplastid DNA-based PCR as a gold standard, the real-time PCR had sensitivity and specificity values of 92% and 77%, respectively, which were significantly higher than those of conventional tests such as microscopy, culture and the leishmanin skin test (LST. In addition, the real-time PCR identified 147 different clinical samples at the species level, providing an overall agreement of 100% when compared to multilocus sequence typing (MLST data performed on a subset of these samples. Furthermore, the real-time PCR was three times faster and five times less expensive when compared to PCR - MLST for species identification from clinical specimens. In summary, this new assay represents a cost-effective and reliable alternative for the identification of the main species causing NWTL in South America.

1982-01-01

Time series analysis is applied to model human operator dynamics in pursuit and compensatory tracking modes. The normalized residual criterion is used as a one-step analytical tool to encompass the processes of identification, estimation, and diagnostic checking. A parameter constraining technique is introduced to develop more reliable models of human operator dynamics. The human operator is adequately modeled by a second order dynamic system both in pursuit and compensatory tracking modes. In comparing the data sampling rates, 100 msec between samples is adequate and is shown to provide better results than 200 msec sampling. The residual power spectrum and eigenvalue analysis show that the human operator is not a generator of periodic characteristics.

Early and adequate antimicrobial therapy has been shown to improve the clinical outcome in bloodstream infections (BSI). To provide rapid pathogen identification for targeted treatment, we applied matrix-assisted laser desorption-ionization time of flight (MALDI-TOF) mass spectrometry fingerprinting to bacteria directly recovered from blood culture bottles. A total of 304 aerobic and anaerobic blood cultures, reported positive by a Bactec 9240 system, were subjected in parallel to differential centrifugation with subsequent mass spectrometry fingerprinting and reference identification using established microbiological methods. A representative spectrum of bloodstream pathogens was recovered from 277 samples that grew a single bacterial isolate. Species identification by direct mass spectrometry fingerprinting matched reference identification in 95% of these samples and worked equally well for aerobic and anaerobic culture bottles. Application of commonly used score cutoffs to classify the fingerprinting results led to an identification rate of 87%. Mismatching mostly resulted from insufficient bacterial numbers and preferentially occurred with Gram-positive samples. The respective spectra showed low concordance to database references and were effectively rejected by score thresholds. Spiking experiments and examination of the respective study samples even suggested applicability of the method to mixed cultures. With turnaround times around 100 min, the approach allowed for reliable pathogen identification at the day of blood culture positivity, providing treatment-relevant information within the critical phase of septic illness.

Purpose: Time-dose relationships have proven important in many cancer sites. This study evaluates the time factors involved in the successful postoperative radiotherapy of medulloblastoma, based on a 30-year experience in a single institution. Methods and Materials: Fifty-three patients with medulloblastoma received postoperative craniospinal radiotherapy with curative intent between 1963 and 1993. Seven patients (13%) underwent biopsy alone, 28 patients (53%) had subtotal excision, and 18 patients (34%) had gross total excision. Eleven patients received adjuvant chemotherapy. The mean posterior fossa dose was 53.1 Gy; most patients received 54.0 Gy (range, 34.3 to 69.6 Gy). For 41 patients receiving once-a-day therapy, the mean dose was 50.6 Gy (range, 34.3 to 56.0 Gy). For 12 patients receiving twice-a-day therapy, the mean dose was 61.8 Gy (range, 52.6 to 69.6 Gy). Minimum follow-up was 2 years, and median follow-up was 10.7 years. Survival, freedom from relapse, and disease control in the posterior fossa were calculated using the Kaplan-Meier method, and multivariate analysis was performed for prognostic factors. Variables related to radiotherapy were examined, including dose to the craniospinal axis, dose to the posterior fossa, fractionation (once-a-day vs. twice-a-day), use of adjuvant chemotherapy, risk group [high (≥T3b or ≥M1) or low (≤T3a and M0-MX)], interval between surgery and radiotherapy (excluding patients receiving chemotherapy before radiotherapy), and duration of radiotherapy. Results: At 5 and 10 years, overall survival rates were 68 and 64%, respectively, and freedom-from-relapse rates were 61 and 52%, respectively. Rates of disease control in the posterior fossa at 5 and 10 years were 79 and 68%, respectively. At 5 years, absolute survival rates after biopsy alone, subtotal excision, and gross total excision were 43, 67, and 78%, respectively (p = 0.04), and posterior fossa control rates were 27, 89, and 83%, respectively (p = 0

Rabies is endemic in wildlife or domestic carnivore populations globally. Infection of domestic dogs is of particular concern in many areas. In regions where domestic animals are at risk of exposure to rabies virus, dogs should be routinely vaccinated against rabies to protect both pet and human populations. Many countries require demonstration of an adequate level of serum rabies neutralizing antibodies to permit entry of dogs during international travel. We analysed rabies titres of dogs seeking travel certification in Israel to assess demographic and vaccine history factors associated with antibody titres below the acceptable threshold for travel certification. Having received only one previous rabies vaccination and a longer duration since the most recent vaccination was received were primary risk factors for not achieving an adequate rabies virus neutralizing antibody titre for travel certification. These risk factors had stronger effects in younger animals, but were consistent for dogs of all ages. In particular, these findings reiterate the importance of administering at least two rabies vaccinations (the primo vaccination and subsequent booster) to ensure population-level protection against rabies in dogs globally. © 2016 Blackwell Verlag GmbH.

Some of the issues involved in selecting adequate models for time series data are discussed using an example concerning the number of users of an Internet server. The process of selecting an appropriate model is subjective and requires experience and judgment. The authors believe an important...... consideration in model selection should be parameter parsimony. They favor the use of parsimonious mixed ARMA models, noting that research has shown that a model building strategy that considers only autoregressive representations will lead to non-parsimonious models and to loss of forecasting accuracy....

We analyzed the correlation between well-established biological parameters of prognostic relevance in B-cell chronic lymphocytic leukemia (CLL) [i.e. mutational status of the immunoglobulin heavy chain variable region (IgV(H)), ZAP-70- and CD38-expression] and serum levels of CD26 (dipeptidyl peptidase IV, DPP IV) by evaluating the impact of these variables on the time to first treatment (TFT) in a series of 69 previously untreated Binet stage A B-cell CLL patients. By using a commercial ELISA we found that with exception of a borderline significance for ZAP-70 (P = 0.07) and CD38 (P = 0.08), circulating levels of CD26 did not correlate with either Rai substages (P = 0.520) or other biomarker [beta2-microglobulin (P = 0.933), LDH (P = 0.101), mutational status of IgV(H) (P = 0.320)]. Maximally selected log-rank statistic plots identified a CD26 serum concentration of 371 ng/mL as the best cut-off. This threshold allowed the identification of two subsets of patients with CD26 serum levels higher and lower that 371 ng/mL respectively, whose clinical outcome was different with respect to TFT (i.e. 46% and 71% at 5 yr respectively; P = 0.005). Along with higher serum levels of CD26, the univariate Cox proportional hazard model identified absence of mutation in IgV(H) (P IgV(H,)P IgV(H) can be adequately used to predict clinical behavior of patients with low risk disease.

This study builds upon and extends the social-identity-based model of cooperation with the organization (T. R. Tyler, 1999; T. R. Tyler & S. L. Blader, 2000) to examine commitment and cooperative intent among fundraising volunteers. In Study 1, structural equation modeling indicated that pride and respect related to the intent to remain a volunteer with an organization, and that this relation was mediated primarily by normative organizational commitment. In Study 2, structural equation modeling indicated that the perceived importance of volunteer work was related to pride, that perceived organizational support related to the experience of respect, and that pride and respect mediated the relation between perceived importance and support on the one hand and organizational commitment on the other. Overall, the results suggest that volunteer organizations may do well to implement pride and respect in their volunteer policy, for instance to address the reliability problem (J. L. Pearce, 1993). 2007 APA, all rights reserved

[Functional restoration--it depends on an adequate mixture of treatment].

Pfingsten, M

2001-12-01

impairment as well as physical variables (mobility, strength) have limited predictive value. Return to work and pain reduction are much better predicted by length of absence from work, application for pension, and the patients' disability in daily-life activities. In the last five years another important variable of success has been identified: avoidance behavior has been suspected to be a major contributor to the initiation and maintenance of chronic low back pain. The perpetuation of avoidance behavior beyond normal healing time subsequently leads to negative consequences such as "disuse syndrome", which is associated with physical deconditioning, sick role behavior, psychosocial withdrawal and negative affect. Accordingly, fear-avoidance beliefs were strongly related to absenteeism from work due to back pain and were the best predictors of therapy outcome in 300 acute low back pain patients. In a prospective study on 87 patients with chronic low back pain (CLBP) we demonstrated that fear-avoidance beliefs were the strongest predictors of return to work after a functional restoration treatment program. Although nonspecific mechanisms such as emotional disturbance, helplessness, pain anticipation, disability, and job circumstances could be identified as influencing the chronic pain process, we have to remember that long-lasting experience of pain is usually a very individual process in which several conditions may work together in a unique combination. Treatment procedures must consider this variability by focusing on general mechanisms, as well as on individual conditions and deficits. FR treatment strongly depends on behavioral principles that rule the whole therapeutic process: Adequate information is necessary to overcome unhelpful beliefs; information has to be related to the patients' daily experiences and their mental capability to understand them.

Full Text Available Abstract The effect of restoration depth on the curing time of a conventional and two bulk-fill composite resins by measuring microhardness and the respective radiosity of the bottom surface of the specimen was investigated. 1-, 3- and 5-mm thick washers were filled with Surefil SDR Flow–U (SDR, Tetric EvoCeram Bulk Fill-IVA (TEC or Esthet-X HD–B1 (EHD, and cured with Bluephase® G2 for 40s. Additional 1-mm washers were filled with SDR, TEC or EHD, placed above the light sensor of MARC®, stacked with pre-cured 1-, 3- or 5-mm washer of respective material, and cured for 2.5~60s to mimic 2-, 4- and 6-mm thick composite curing. The sensor measured the radiosity (EB at the bottom of specimen stacks. Vickers hardness (VH was measured immediately at 5 locations with triplicate specimens. Nonlinear regression of VH vs EB by VH=α[1-exp(-EB/β] with all thickness shows that the values of α, maximum hardness, are 21.6±1.0 kg/mm2 for SDR, 38.3±0.6 kg/mm2 for TEC and 45.3±2.6 kg/mm2 for EHD, and the values of β, rate parameter, are 0.40±0.06 J/cm2 for SDR, 0.77±0.04 J/cm2 for TEC and 0.58±0.09 J/cm2 for EHD. The radiosity of the bottom surface was calculated when the bottom surface of each material attained 80% of α of each material. The curing times for each material are in agreement with manufacturer recommendation for thickness. It is possible to estimate time needed to cure composite resin of known depth adequately by the radiosity and microhardness of the bottom surface.

To determine the time required for the partial pressure of arterial oxygen (PaO2) to reach equilibrium after a 0.20 increment or decrement in fractional inspired oxygen concentration (FIO2) during mechanical ventilation. A multi-disciplinary ICU in a university hospital. Twenty-five adult, non-COPD patients with stable blood gas values (PaO2/FIO2 > or = 180 on the day of the study) on pressure-controlled ventilation (PCV). Following a baseline PaO2 (PaO2b) measurement at FIO2 = 0.35, the FIO2 was increased to 0.55 for 30 min and then decreased to 0.35 without any other change in ventilatory parameters. Sequential blood gas measurements were performed at 3, 5, 7, 9, 11, 15, 20, 25 and 30 min in both periods. The PaO2 values measured at the 30th min after a step change in FIO2 (FIO2 = 0.55, PaO2[55] and FIO2 = 0.35, PaO2[35]) were accepted as representative of the equilibrium values for PaO2. Each patient's rise and fall in PaO2 over time, PaO2(t), were fitted to the following respective exponential equations: PaO2b + (PaO2[55]-PaO2b)(1-e-kt) and PaO2[55] + (PaO2[35]-PaO2[55])(e-kt) where "t" refers to time, PaO2[55] and PaO2[35] are the final PaO2 values obtained at a new FIO2 of 0.55 and 0.35, after a 0.20 increment and decrement in FIO2, respectively. Time constant "k" was determined by a non-linear fitting curve and 90% oxygenation times were defined as the time required to reach 90% of the final equilibrated PaO2 calculated by using the non-linear fitting curves. Time constant values for the rise and fall periods were 1.01 +/- 0.71 min-1, 0.69 +/- 0.42 min-1, respectively, and 90% oxygenation times for rises and falls in PaO2 periods were 4.2 +/- 4.1 min-1 and 5.5 +/- 4.8 min-1, respectively. There was no significant difference between the rise and fall periods for the two parameters (p > 0.05). We conclude that in stable patients ventilated with PCV, after a step change in FIO2 of 0.20, 5-10 min will be adequate for obtaining a blood gas sample to measure a Pa

Background: The German Society of Radiation Oncology ('Deutsche Gesellschaft fuer Radioonkologie', DEGRO) initiated a multicenter trial to develop and evaluate adequate modules to assert core processes and subprocesses in radiotherapy. The aim of this prospective evaluation was to methodical assess the required resources (technical equipment and medical staff) for stereotactic radiotherapy/radiosurgery. Material and methods: At two radiotherapy centers of excellence (University Hospitals of Heidelberg and Marburg/Giessen), the manpower and time required for the implementation of intra- and extracranial stereotactic radiotherapy was prospectively collected consistently over a 3-month period. The data were collected using specifically developed process acquisition tools and standard forms and were evaluated using specific process analysis tools. Results: For intracranial (extracranial) fractionated stereotactic radiotherapy (FSRT) and radiosurgery (RS), a total of 1,925 (270) and 199 (36) records, respectively, could be evaluated. The approximate time needed to customize the immobilization device was median 37 min (89 min) for FRST and 31 min (26 min) for RS, for the contrast enhanced planning studies 22 and 27 min (25 and 28 min), for physical treatment planning 122 and 59 min (187 and 27 min), for the first and routine radiotherapy sessions for FSRT 40 and 13 min (58 and 31 min), respectively. The median time needed for the RS session was 58 min (45 min). The corresponding minimal manpower needed was 2 technicians for customization of the immobilization device, 2.5 technicians and 1 consultant for the contrast-enhanced planning studies, 1 consultant, 0.5 resident and 0.67 medical physics expert (MPE) for physical treatment planning, as well as 1 consultant, 0.5 resident, and 2.5 technicians for the first radiotherapy treatment and 2.33 technicians for routine radiotherapy sessions. Conclusion: For the first time, the resource requirements for a

It is well known that excess adiposity during childhood may influence pubertal development. However, the extent to which body compositions vary in throughout puberty in boys and girls is currently unknown. The aim of this study was to investigate whether obesity and body compositions correlate with the timing of puberty in boys and girls. By random cluster sampling, our study analyzed data from 1472 students (690 girls, 782 boys) aged 6-17 years from two schools in the Chongqing area. Data were collected by physical examination of weight, height, and skinfold thicknesses. Testicular volume was measured in boys and breast development in girls. By which we got the indicators of obesity, timing of puberty and body compositions. Probit regression analysis was used to group subjects into early puberty (>P 25 ), on-time puberty (P 25  ~ P 75 ), and delayed puberty (puberty groups by sex. Multivariate analysis of covariance was used to examine the association between timing of puberty and body composition indicators. There were significant differences in the distribution of fat levels (normal weigh, overweight, obesity) among different pubertal groups in different sex (boys:χ2 = 10.639, P = 0.031; girls:χ2 = 63.232, P = 0.000). Multivariate analysis of covariance showed that percentage of body fat, fat mass and fat-free mass in the delayed puberty girls were significantly lower than the girls in the on-time puberty and early puberty, while body density had the opposite result (all P puberty groups (all P > 0.05). In girls, delayed puberty was negatively correlated with Obesity, percentage of body fat, fat mass and fat-free mass, and positively correlated with body density. But in boys, delayed puberty was only negatively correlated with Obesity, the relation between puberty and body compositions was not found.

Respect is important in the creation of a positive perioperative work environment and effective OR teams. Low scores for respect in the OR on an employee opinion survey and responses on a more customized survey that examined issues associated with respect prompted leaders at the University Health Network to undertake a multiyear organizational strategy to address respect and quality of worklife initiatives. An interprofessional quality of worklife task force convened to create an action plan to address the outcomes of the surveys. The work of the task force included developing and implementing a code of conduct team charter for the OR, empowering leaders to better manage conflict through education and coaching, creating a collaborative, consistent approach to conflict resolution, and designing an education strategy for staff members to enhance communication and conflict resolution. Results of recent employee opinion surveys have reflected positive outcomes. Efforts to sustain the effects of the project include quarterly recognition awards and ongoing education focused on wellness and communication skills. Copyright © 2011 AORN, Inc.

Singh-Carlson, Savitri; Neufeld, Anne; Olson, Joanne

2010-01-01

The purpose of this focused ethnographic inquiry was to examine South Asian immigrant women's experiences and perceptions of respect within health professional-client relationships in the context of a Canadian outpatient treatment clinic. Characteristics of respect described by 11 women interviewed were the meaning of respect, health professional's way of being, their way of attending to the person, and their way of talking. Language, cultural values and beliefs, along with underlying societal, individual and institutional factors that coexist with health professionals' ability to create respect were some of the dimensions that influenced how immigrant women experienced respect. Health professionals' capacity to acknowledge South Asian immigrant women as individuals helped to formulate/construct respect for their individual identities. The need to be respected for 'my social identity' as an immigrant woman with cancer was woven throughout women's stories, illustrated by their personal experiences and perspectives.

Structure and Hierarchy in Real-Time Systems

DEFF Research Database (Denmark)

Möller, Michael Oliver

The development of digital systems is particularly challenging, if their correctness depends on the right timing of operations. One approach to enhance the reliability of such systems is model-based development. This allows for a formal analysis throughout all stages of design. Model......-based development is hindered mainly by the lack of adequate modeling languages and the high computational cost of the analysis. In this thesis we improve the situation along both axes. First, we bring the mathematical model closer to the human designer. This we achieve by casting hierarchical structures--as known...... that have the potential to reduce time and memory consumption drastically. The first technique makes use of structural information, in particular loops, to exploit regularities in the reachable state space. Via shortcut-like additions to the model we avoid repetition of similar states during an exhaustive...

Autonomy and the principle of respect for autonomy.

Science.gov (United States)

Gillon, R

1985-06-15

Autonomy is defined as the capacity to think, decide, and act freely and independently on the basis of such thought and decisions. Three types of autonomy are distinguished: autonomy of thought, which embraces the wide range of human intellectual activities called "thinking for oneself"; autonomy of will, or the capacity to decide to do things on the basis of one's deliberations; and autonomy of action, the absence of which is illustrated by the situation of a patient whose voluntary muscles are paralyzed by curariform drugs and who thus cannot tell the surgeon that the anesthetist has forgotten the nitrous oxide. Autonomy is viewed as a prerequisite for all the virtues, rather than as a virtue in its own right. The arguments of Immanuel Kant and John Stuart Mill concerning the principle of respect for autonomy are summarized as exemplars respectively of the deontological and utilitarian philosophical approaches.

Adequateness of applying the Zmijewski model on Serbian companies

Full Text Available The aim of the paper is to determine the accuracy of the prediction of Zmijewski model in Serbia on the eligible sample. At the same time, the paper identifies model's strengths, weaknesses and limitations of its possible application. Bearing in mind that the economic environment in Serbia is not similar to the United States at the time the model was developed, Zmijewski model is surprisingly accurate in the case of Serbian companies. The accuracy was slightly weaker than the model results in the U.S. in its original form, but much better than the results model gave in the U.S. in the period 1988-1991, and 1992-1999. Model gave also better results in Serbia comparing those in Croatia, even in Croatia model was adjusted.

Verifying Real-Time Systems using Explicit-time Description Methods

Directory of Open Access Journals (Sweden)

Hao Wang

2009-12-01

Full Text Available Timed model checking has been extensively researched in recent years. Many new formalisms with time extensions and tools based on them have been presented. On the other hand, Explicit-Time Description Methods aim to verify real-time systems with general untimed model checkers. Lamport presented an explicit-time description method using a clock-ticking process (Tick to simulate the passage of time together with a group of global variables for time requirements. This paper proposes a new explicit-time description method with no reliance on global variables. Instead, it uses rendezvous synchronization steps between the Tick process and each system process to simulate time. This new method achieves better modularity and facilitates usage of more complex timing constraints. The two explicit-time description methods are implemented in DIVINE, a well-known distributed-memory model checker. Preliminary experiment results show that our new method, with better modularity, is comparable to Lamport's method with respect to time and memory efficiency.

This paper aims to determinate the water flowrate using Time Transient and Cross-Correlation techniques. The detection system uses two NaI (T1) detectors adequately positioned on the outside of pipe and a gamma-ray source ( 82 Br radiotracer). The water flowrate measurements using Time Transient and Cross-Correlation techniques were compared to invasive conventional measurements of the flowrate previously installed in pipeline. Discrepancies between Time Transient and Cross-Correlation techniques flowmeter previously installed in pipeline. Discrepancies between Time Transient and Cross-Correlation techniques flowrate values were found to be less than 3% in relation to conventional ones. (author)

Previous epidemiological studies have conflicting suggestions on the association of occupational injury risks with employment category across industries. This specific issue has not been examined for direct patient care occupations in the health care sector. To investigate whether work-related injury rates differ by employment category (part time, full time or casual) for registered nurses (RNs) in acute care and care aides (CAs) in long-term facilities. Incidents of occupational injury resulting in compensated time loss from work, over a 1-year period within three health regions in British Columbia (BC), Canada, were extracted from a standardized operational database. Detailed analysis was conducted using Poisson regression modeling. Among 8640 RNs in acute care, 37% worked full time, 24% part time and 25% casual. The overall rates of injuries were 7.4, 5.3 and 5.5 per 100 person-years, respectively. Among the 2967 CAs in long-term care, 30% worked full time, 20% part time and 40% casual. The overall rates of injuries were 25.8, 22.9 and 18.1 per 100 person-years, respectively. In multivariate models, having adjusted for age, gender, facility and health region, full-time RNs had significantly higher risk of sustaining injuries compared to part-time and casual workers. For CAs, full-time workers had significantly higher risk of sustaining injuries compared to casual workers. Full-time direct patient care occupations have greater risk of injury compared to part-time and casual workers within the health care sector.

Development of adequate meteorological monitoring standards for safety analysis of nuclear facilities

International Nuclear Information System (INIS)

Alp, E.; Lewis, P.J.

1985-09-01

The aim of this report is to identify what constitutes adequate meteorological information for airborne dispersion calculations in case of releases from nuclear facilities during 'normal operation', 'design postulated accidents', and 'emergency situations'. The models used for estimating downwind dispersion are reviewed, including short-range simple terrain, short-range complex terrain and medium to long range models with emphasis on Lagrangian models. The meteorogolical input parameters required for running these models are identified. The methods by which these parameters may be obtained from raw meteorological data are then considered. Emphasis is placed on well-tried and recommended methods rather than those which are currently being developed and lack long-term field tests. The meteorological data required to calculate the parameters that are in turn input to dispersion calculation methods can be obtained mainly from tower measurements. Recommended tower height is 50 m, with two levels of instruments (10 and 50 m) for wind speed, wind direction and temperature. Data for precipitation and solar radiation, that may be required under certain conditions and for special calculations, may be estimated from nearby representative weather stations (if available). For simple terrain, a single tower is sufficient. For complex terrain, such as coastal regions, two towers are desirable for accurate characterization of the turbulence regime in the vicinity of a release site. The report provides the necessary accuracy specifications for instruments required for the meteorological measurements. Data monitoring and recording, maintenance, quality control and assurance are also discussed. Error propagation analyses are recommended to determine the full implications of instrument accuracies on the accuracy of dispersion model predictions. 82 refs

Over the past several years, NASA has realized tremendous progress in technology development that is aimed at the production of an Advanced Extravehicular Mobility Unit (AEMU). Of the many functions provided by the spacesuit and portable life support subsystem within the AEMU, delivering breathing gas to the astronaut along with removing the carbon dioxide (CO2) remains one of the most important environmental functions that the AEMU can control. Carbon dioxide washout is the capability of the ventilation flow in the spacesuit helmet to provide low concentrations of CO2 to the crew member to meet breathing requirements. CO2 washout performance is a critical parameter needed to ensure proper and sufficient designs in a spacesuit and in vehicle applications such as sleep stations and hygiene compartments. Human testing to fully evaluate and validate CO2 washout performance is necessary but also expensive due to the levied safety requirements. Moreover, correlation of math models becomes challenging because of human variability and movement. To supplement human CO2 washout testing, a breathing capability will be integrated into a suited manikin test apparatus to provide a safe, lower cost, stable, easily modeled alternative to human testing. Additionally, this configuration provides NASA Johnson Space Center (JSC) the capability to evaluate CO2 washout under off-nominal conditions that would otherwise be unsafe for human testing or difficult due to fatigue of a test subject. Testing has been under way in-house at JSC and analysis has been initiated to evaluate whether the technology provides sufficient performance in ensuring that the CO2 is removed sufficiently and the ventilation flow is adequate for maintaining CO2 washout in the AEMU spacesuit helmet of the crew member during an extravehicular activity. This paper will review recent CO2 washout testing and analysis activities, testing planned in-house with a spacesuit simulator, and the associated analytical work

Real-time exception handling—Use cases and response requirements

2012-01-01

Adequate real-time event detection and exception handling for machine protection and plasma optimization are important for safe and efficient operation of fusion devices. Within the scope of a layered protection hierarchy, the exception handling goals of the real-time control system are to optimize control performance, switch to alternate investigations, terminate the discharge in a controlled way, or alarm the interlock system when control is lost. Analysis of these goals shows that they can be implemented with two methods: the modification of the reference values to respond to degradation of sensors, actuators or controllers, and the replacement of schedules to perform other investigations, which includes controlled termination and interlock alarm cases. In support of these methods the sensor and evaluated data quality and the time-varying actuator characteristics and capacity must be communicated to users of those information to avoid failure propagation.

Although there is still some skepticism in the biological community regarding the value and significance of quantitative computational modeling, important steps are continually being taken to enhance its accessibility and predictive power. We view these developments as essential components of an emerging 'respectful modeling' framework which has two key aims: (i) respecting the models themselves and facilitating the reproduction and update of modeling results by other scientists, and (ii) respecting the predictions of the models and rigorously quantifying the confidence associated with the modeling results. This respectful attitude will guide the design of higher-quality models and facilitate the use of models in modern applications such as engineering and manipulating microbial metabolism by synthetic biology.

Sirenians are the only extant herbivorous mammals fully adapted to an aquatic lifestyle. They originated in Africa during the Paleocene from an undetermined clade of afrotherian mammals, and by the end of the Eocene they were widely distributed across the tropical latitudes. Here we introduce Sobrarbesiren cardieli gen. et sp. nov. It is the first adequately-known quadrupedal sirenian from Eurasia and the oldest record of this clade from western Europe. Fossils have been recovered from the middle Lutetian (SBZ15) site of Castejón de Sobrarbe-41 (Huesca, Spain), and comprise many cranial and postcranial remains, including pelvic girdle and hind limb bones, from at least six sirenian individuals of different ontogenetic stages. Sobrarbesiren shows a suite of characters previously considered synapomorphies of different clades of derived sirenians, such as the presence of the processus retroversus of the squamosal and the pterygoid fossa, combined with ancestral characters such as the presence of an alisphenoid canal, a permanent P5, at least two sacral vertebrae, a primitive pelvis and functional femora and fibulae. Sobrarbesiren is recovered as the sister taxon of Dugongidae and represents a transitional stage of adaptation to aquatic life between the amphibious quadrupedal prorastomids and the aquatic quadrupedal protosirenids.

Residence time modeling of hot melt extrusion processes.

Science.gov (United States)

Reitz, Elena; Podhaisky, Helmut; Ely, David; Thommes, Markus

2013-11-01

The hot melt extrusion process is a widespread technique to mix viscous melts. The residence time of material in the process frequently determines the product properties. An experimental setup and a corresponding mathematical model were developed to evaluate residence time and residence time distribution in twin screw extrusion processes. The extrusion process was modeled as the convolution of a mass transport process described by a Gaussian probability function, and a mixing process represented by an exponential function. The residence time of the extrusion process was determined by introducing a tracer at the extruder inlet and measuring the tracer concentration at the die. These concentrations were fitted to the residence time model, and an adequate correlation was found. Different parameters were derived to characterize the extrusion process including the dead time, the apparent mixing volume, and a transport related axial mixing. A 2(3) design of experiments was performed to evaluate the effect of powder feed rate, screw speed, and melt viscosity of the material on the residence time. All three parameters affect the residence time of material in the extruder. In conclusion, a residence time model was developed to interpret experimental data and to get insights into the hot melt extrusion process. Copyright © 2013 Elsevier B.V. All rights reserved.

Respect distances. Rationale and means of computation

Munier, Raymond [Swedish Nuclear Fuel and Waste Management Co., Stockholm (Sweden); Hoekmark, Harald [Clay Technology, Lund (Sweden)

2004-12-01

Canisters with spent nuclear fuel can obviously not be located within deformation zones as this might jeopardise their long term mechanical stability and thereby constitute a potential hazard to the biosphere. Less apparent, but equally important, is the fact that earthquakes trigger reactivation, slip, of structures some distance from their hypocentres due to, among many other factors, stress redistribution. Fault slip across a deposition hole might damage the isolation capacity of the canister and thereby jeopardise the overall integrity of the barrier system. Therefore, the following question might be posed: What is the distance from a deformation zone beyond which a canister can be safely emplaced? This respect distance cannot be readily computed because, unknown future events aside, there are some complicated aspects that need to be addressed e.g. degree of conservatism, scale, our ability to model ice sheets and earthquakes, etc. In this report we discuss various aspects of the assignment of respect distances, propose a methodology for its assignment and apply the methodology to the Forsmark Site as a worked example. Our main concern, in the context discussed in this report, is the post glacial faults anticipated to occur after the next glaciations. To properly address conservativeness, analysis of risk, and its implementation in safety analysis, we provide an extensive compilation of our current knowledge on post glacial faults as an appendix.

A Social Recognition Approach to Autonomy: The Role of Equality-Based Respect.

Science.gov (United States)

Renger, Daniela; Renger, Sophus; Miché, Marcel; Simon, Bernd

2017-04-01

Inspired by philosophical reasoning about the connection between equality and freedom, we examined whether experiences of (equality-based) respect increase perceived autonomy. This link was tested with generalized experiences of respect and autonomy people make in their daily lives (Study 1) and with more specific experiences of employees at the workplace (Study 2). In both studies, respect strongly and independently contributed to perceived autonomy over and above other forms of social recognition (need-based care and achievement-based social esteem) and further affected (life/work) satisfaction. Study 3 experimentally confirmed the hypothesized causal influence of respect on perceived autonomy and demonstrated that this effect further translates into social cooperation. The respect-cooperation link was simultaneously mediated by perceived autonomy and superordinate collective identification. We discuss how the recognition approach, which differentiates between respect, care, and social esteem, can enrich research on autonomy.

Improved ASTM G72 Test Method for Ensuring Adequate Fuel-to-Oxidizer Ratios

Science.gov (United States)

Juarez, Alfredo; Harper, Susana Tapia

2016-01-01

The ASTM G72/G72M-15 Standard Test Method for Autogenous Ignition Temperature of Liquids and Solids in a High-Pressure Oxygen-Enriched Environment is currently used to evaluate materials for the ignition susceptibility driven by exposure to external heat in an enriched oxygen environment. Testing performed on highly volatile liquids such as cleaning solvents has proven problematic due to inconsistent test results (non-ignitions). Non-ignition results can be misinterpreted as favorable oxygen compatibility, although they are more likely associated with inadequate fuel-to-oxidizer ratios. Forced evaporation during purging and inadequate sample size were identified as two potential causes for inadequate available sample material during testing. In an effort to maintain adequate fuel-to-oxidizer ratios within the reaction vessel during test, several parameters were considered, including sample size, pretest sample chilling, pretest purging, and test pressure. Tests on a variety of solvents exhibiting a range of volatilities are presented in this paper. A proposed improvement to the standard test protocol as a result of this evaluation is also presented. Execution of the final proposed improved test protocol outlines an incremental step method of determining optimal conditions using increased sample sizes while considering test system safety limits. The proposed improved test method increases confidence in results obtained by utilizing the ASTM G72 autogenous ignition temperature test method and can aid in the oxygen compatibility assessment of highly volatile liquids and other conditions that may lead to false non-ignition results.

Proposal for a advanced PWR core with adequate characteristics for passive safety concept

Perrotta, Jose Augusto

1999-01-01

This work presents a discussion upon the suitable from an advanced PWR core, classified by the EPRI as 'Passive PWR' (advanced reactor with passive safety concept to power plants with less than 600 MW electrical power). The discussion upon the type of core is based on nuclear fuel engineering concepts. Discussion is made on type of fuel materials, structural materials, geometric shapes and manufacturing process that are suitable to produce fuel assemblies which give good performance for this type of reactors. The analysis is guided by the EPRI requirements for Advanced Light Water Reactor (ALWR). By means of comparison, the analysis were done to Angra 1 (old type of 600 MWe PWR class), and the design of the Westinghouse Advanced PWR-AP600. It was verified as a conclusion of this work that the modern PWR fuels are suitable for advanced PWR's Nevertheless, this work presents a technical alternative to this kind of fuel, still using UO 2 as fuel, but changing its cylindrical form of pellets and pin type fuel element to plane shape pallets and plate type fuel element. This is not a novelty fuel, since it was used in the 50's at Shippingport Reactor and as an advanced version by CEA of France in the 70's. In this work it is proposed a new mechanical assembly design for this fuel, which can give adequate safety and operational performance to the core of a 'Passive PWR'. (author)

Kam, Sung Chul; Han, Deok Hyun; Lee, Sung Won

2011-03-01

Premature ejaculation (PE) is the most prevalent male ejaculation disorder. The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the DSM-IV-TR criteria in diagnostic PE. To evaluate the diagnostic value of the PEDT and its association with intravaginal ejaculatory latency time (IELT). (i) Korean validation of PEDT: data was collected from men interviewed by one of the two clinical experts, who made a diagnostic of present or absence of PE, using DSM-IV-TR criteria. A total of 103 patients with PE and 100 men without PE were enrolled into the study and requested to complete the PEDT; and (ii) The correlation between IELT and PEDT: 200 participants were enrolled and each participant was asked to make out PEDT. All participants were requested to measure IELT. Validity and reliability of the PEDT and its association with IELT. The geometric mean IELT of the PE group was 115.37 ± 78.14 seconds. The number of men reporting IELTs of 2 minutes were 28 (28.6%), 29 (29.6%), and 41 (41.8%), respectively. The Cronbach's alpha score was calculated as 0.93, showing adequate internal consistency. The test-retest correlation coefficients of each item were higher than 0.72 and the correlation coefficients of the total score was 0.88. (P IELT showed an adequate negative correlation. (ρ = -0.77, P IELT ≤ 2 minutes) and IELT showed a negative correlation. (ρ = -0.6, P < 0.0001) The PEDT was highly effective in detecting the presence of PE. The result of our study supports its validity as a diagnostic tool in the clinical setting. © 2010 International Society for Sexual Medicine.

Objective: To investigate the feasibility of targeting various areas of left ventricle myocardium under real time magnetic resonance (MR) imaging with a customised injection catheter equipped with a miniaturised coil. Design: A needle injection catheter with a mounted resonant solenoid circuit (coil) at its tip was designed and constructed. A 1.5 T MR scanner with customised real time sequence combined with in-room scan running capabilities was used. With this system, various myocardial areas within the left ventricle were targeted and injected with a gadolinium-diethylenetriaminepentaacetic acid (DTPA) and Indian ink mixture. Results: Real time sequencing at 10 frames/s allowed clear visualisation of the moving catheter and its transit through the aorta into the ventricle, as well as targeting of all ventricle wall segments without further image enhancement techniques. All injections were visualised by real time MR imaging and verified by gross pathology. Conclusion: The tracking device allowed real time in vivo visualisation of catheters in the aorta and left ventricle as well as precise targeting of myocardial areas. The use of this real time catheter tracking may enable precise and adequate delivery of agents for tissue regeneration. PMID:15710717

We aimed to understand the characteristics of patients who are less likely to submit adequate urine collections at metabolic stone evaluation. Inadequate urine collection was defined using two definitions: (1) Reference ranges for 24-hour creatinine/kilogram (Cr/24) and (2) discrepancy in total 24-hour urine Cr between 24-hour urine collections. There were 1502 patients with ≥1 kidney stone between 1998 and 2014 who performed a 24- or 48-hour urine collection at Northwestern Memorial Hospital and who were identified retrospectively. Multivariate analysis was performed to analyze predictor variables for adequate urine collection. A total of 2852 urine collections were analyzed. Mean age for males was 54.4 years (range 17-86), and for females was 50.2 years (range 8-90). One patient in the study was younger than 17 years old. (1) Analysis based on the Cr 24/kg definition: There were 50.7% of patients who supplied an inadequate sample. Females were nearly 50% less likely to supply an adequate sample compared with men, Pcollections were achieved in 82.8%, 66.9%, 51.7%, 38.5%, and 26.4% of patients, respectively. Statistical significance was observed based on differences of ≥40%, and this was defined as the threshold for an inadequate sample. Female sex (OR 0.73 [0.54-0.98], P=0.037) predicted supplying inadequate samples. Adequate collections were more likely to be received on a Sunday (OR 1.6 [1.03-2.58], P=0.038) and by sedentary workers (OR 2.3 [1.12-4.72], P=0.023). Urine collections from patients during metabolic evaluation for nephrolithiasis may be considered inadequate based on two commonly used clinical definitions. This may have therapeutic or economic ramifications and the propensity for females to supply inadequate samples should be investigated further.

2015-05-01

Full Text Available Purpose: determining of self-respect level and assertiveness of teachers. Verification of whether there is a relationship between the measured trait and the correlation of educational competence. Material and methods: the study used three tools: Polish adaptation of SES M.Rosenberg's Self Esteem Scale, a questionnaire to determine the levels of assertiveness - P.Majewicz's Scale "I and others" and a questionnaire to examine the professional competence of teachers by A.Romanowska-Tołłoczko. The study examined 275 primary school teachers of different subjects. Results: after the statement of the research’s results in the field of self-respect and assertiveness, it turns out that there is some regularity in relation to the level of the studied traits. People with high self-respect also receive higher scores assertive skills compared with those of average and low self-respect. This pattern is seen in all groups of teachers. Conclusions: although the observed differences are not great and statistically significant, they show some evidence of the occurrence trend of interdependence in a range of predispositions. Moreover, a positive correlation between the level of self-respect and assertiveness and parental perception of their competence was noted.

Quadratic time dependent Hamiltonians and separation of variables

Science.gov (United States)

Anzaldo-Meneses, A.

2017-06-01

Time dependent quantum problems defined by quadratic Hamiltonians are solved using canonical transformations. The Green's function is obtained and a comparison with the classical Hamilton-Jacobi method leads to important geometrical insights like exterior differential systems, Monge cones and time dependent Gaussian metrics. The Wei-Norman approach is applied using unitary transformations defined in terms of generators of the associated Lie groups, here the semi-direct product of the Heisenberg group and the symplectic group. A new explicit relation for the unitary transformations is given in terms of a finite product of elementary transformations. The sequential application of adequate sets of unitary transformations leads naturally to a new separation of variables method for time dependent Hamiltonians, which is shown to be related to the Inönü-Wigner contraction of Lie groups. The new method allows also a better understanding of interacting particles or coupled modes and opens an alternative way to analyze topological phases in driven systems.

Internally consistent gamma ray burst time history phenomenology

International Nuclear Information System (INIS)

Cline, T.L.

1985-01-01

A phenomenology for gamma ray burst time histories is outlined. Order of their generally chaotic appearance is attempted, based on the speculation that any one burst event can be represented above 150 keV as a superposition of similarly shaped increases of varying intensity. The increases can generally overlap, however, confusing the picture, but a given event must at least exhibit its own limiting characteristic rise and decay times if the measurements are made with instruments having adequate temporal resolution. Most catalogued observations may be of doubtful or marginal utility to test this hypothesis, but some time histories from Helios-2, Pioneer Venus Orbiter and other instruments having one-to several-millisecond capabilities appear to provide consistency. Also, recent studies of temporally resolved Solar Maximum Mission burst energy spectra are entirely compatible with this picture. The phenomenology suggested here, if correct, may assist as an analytic tool for modelling of burst processes and possibly in the definition of burst source populations

When designing complete systems or system components, it is of vital importance for the manufacturers to optimally fulfill the continuously increasing demands pertaining to safety, durability, reduction of energy consumption, noise reduction, improvement of comfort, accuracy, etc. This applies to all types of traffic and transportation systems like rail vehicles, automobiles, airplanes and ships. By combining structural analysis and simulation methods with optimization algorithms, required specifications can be met faster and more reliably, and hence the production development cycles can be substantially reduced. This paper shall give an overview on results of a method with the features of a damage approximation as precisely as possible on the one hand and, on the other hand, a load-time history with few different load cycles so that a nonlinear calculation can be performed in the shortest possible time. Simulations with rigidly and elastically modeled components like bogie frames or carbodies show that depending on the type of modeling substantial differences may occur with respect to dynamic behavior and the interaction quantity between the bodies. This aspect has to be taken into consideration for quantitatively sufficient fatigue strength and durability calculation. Mathematical optimization procedures are in general an efficient tool to guarantee the optimal fulfillment of all required design objectives and constraints in all stages of the design process. Some of the procedures are illustrated at two examples (bogie frame, carbody). (orig.)

Two-Agent Single-Machine Scheduling of Jobs with Time-Dependent Processing Times and Ready Times

Directory of Open Access Journals (Sweden)

Jan-Yee Kung

2013-01-01

Full Text Available Scheduling involving jobs with time-dependent processing times has recently attracted much research attention. However, multiagent scheduling with simultaneous considerations of jobs with time-dependent processing times and ready times is relatively unexplored. Inspired by this observation, we study a two-agent single-machine scheduling problem in which the jobs have both time-dependent processing times and ready times. We consider the model in which the actual processing time of a job of the first agent is a decreasing function of its scheduled position while the actual processing time of a job of the second agent is an increasing function of its scheduled position. In addition, each job has a different ready time. The objective is to minimize the total completion time of the jobs of the first agent with the restriction that no tardy job is allowed for the second agent. We propose a branch-and-bound and several genetic algorithms to obtain optimal and near-optimal solutions for the problem, respectively. We also conduct extensive computational results to test the proposed algorithms and examine the impacts of different problem parameters on their performance.

Allen, K W; Nguyen-Van-Tam, J S; Howells, J

1999-06-01

The discovery that a local travel clinic had administered 101 doses of time-expired yellow fever vaccine over a six month period prompted an immediate investigation in order to advise vaccinees about to travel to areas where yellow fever is endemic. No data were available to provide adequate reassurance about the potential efficacy of time-expired vaccine, so a rapid serological investigation was conducted, which provided evidence that the yellow fever vaccine had remained potent beyond its expiry date.

Global synchronization in finite time for fractional-order neural networks with discontinuous activations and time delays.

Peng, Xiao; Wu, Huaiqin; Song, Ka; Shi, Jiaxin

2017-10-01

This paper is concerned with the global Mittag-Leffler synchronization and the synchronization in finite time for fractional-order neural networks (FNNs) with discontinuous activations and time delays. Firstly, the properties with respect to Mittag-Leffler convergence and convergence in finite time, which play a critical role in the investigation of the global synchronization of FNNs, are developed, respectively. Secondly, the novel state-feedback controller, which includes time delays and discontinuous factors, is designed to realize the synchronization goal. By applying the fractional differential inclusion theory, inequality analysis technique and the proposed convergence properties, the sufficient conditions to achieve the global Mittag-Leffler synchronization and the synchronization in finite time are addressed in terms of linear matrix inequalities (LMIs). In addition, the upper bound of the setting time of the global synchronization in finite time is explicitly evaluated. Finally, two examples are given to demonstrate the validity of the proposed design method and theoretical results. Copyright © 2017 Elsevier Ltd. All rights reserved.

Productivity of Bedouin goats: Coping with shortages of water and adequate food

International Nuclear Information System (INIS)

Choshniak, I.; Brosh, A.; Shkolnik, A.

1988-01-01

The study was carried out under outdoor summer conditions on goats that were watered only once every four days and goats that were watered once daily. Under each of the watering regimes the goats were fed on alfalfa hay (a high quality roughage), and Rhodes grass and wheat straw, medium and low quality feed respectively. In all trials except one, the goats maintained constant body weights. When goats were watered infrequently they gulped down volumes of water that often caused the osmolarity of the rumen fluid to drop from 360 mosm/kg to about 80 mosm/kg. Over this entire range of osmotic concentration the bacterial populations in the goats' rumen maintained their viability. By reducing the fluid flow through the gut, infrequent drinking helped to extend the time the digesta were retained along the digestive tract. As a result, digestibility of the roughage, particularly that of the low quality feed, was improved. Infrequent drinking was found to reduce the animals' demand for metabolizable energy and, as a result, enabled the goat to balance its energy metabolism on a low energy intake. It also improved the balance in the utilization of dietary protein while not interfering with the ability to recycle urea. It is concluded that the effects of the two deficiencies dealt with in this study are by no means additive. Frequent watering of ruminants in the desert is likely to increase their demand for food, lower their gain in digestible energy, increase their demand for metabolizable energy and make it more difficult for them to balance their energy budget. Improving feed quality for animals grazing in the desert, when water availability declines, is also not advantageous. It may only increase the animals' needs for water, render them dependent on frequent drinking and restrict their grazing area to the close vicinity of water sources. 30 refs, 10 figs, 6 tabs

Full Text Available In this paper we derive an integral (with respect to time representation of the relative entropy (or Kullback–Leibler Divergence R(μ||P, where μ and P are measures on C([0,T];Rd. The underlying measure P is a weak solution to a martingale problem with continuous coefficients. Our representation is in the form of an integral with respect to its infinitesimal generator. This representation is of use in statistical inference (particularly involving medical imaging. Since R(μ||P governs the exponential rate of convergence of the empirical measure (according to Sanov’s theorem, this representation is also of use in the numerical and analytical investigation of finite-size effects in systems of interacting diffusions.

To explore the preparedness of final-year physiotherapy students for their progression into employment, and identify what universities can do to facilitate a smooth transition. A single-cohort study, utilising a qualitative design incorporating a survey followed by transcribed and coded semi-structured interviews. Interviews were held in the Placement and Careers Centre at Brunel University, London. Sixty final-year full- and part-time students participated in the survey, and 12 final-year full- and part-time students participated in the semi-structured interviews. Sixty students completed a questionnaire which explored their preparedness for employment. Questions related to the current job situation, the application process and the student's ideal first post. Responses from the questionnaire were analysed and discussed further through a digitally recorded interview. Twelve students were interviewed by an experienced interviewer from a non-physiotherapy background. Students felt unprepared for employment. Forty-seven per cent wanted a rotational post, but 26% would only spend 6 months and 39% would only spend 1 year looking for a job. Seventy-one percent would change career and 99% would work abroad if they were unable to secure a post in the UK. Most importantly, students could not identify transferable skills required by potential employers; only 25% cited effective communications, and 10% cited flexible working as a transferable skill. Self-management skills (e.g. prioritisation, time management and documentation) were not perceived as essential for employment. The job market requires physiotherapy graduates to possess transferable skills which can be applied to any situation. Many are integral to the profession and the undergraduate curriculum; however, analysis and assimilation of these skills cannot be assumed. Universities should reflect on their curriculum delivery to produce graduates who meet employers' expectations and make a smooth transition into the

Mix and Inject: Reaction Initiation by Diffusion for Time-Resolved Macromolecular Crystallography

Directory of Open Access Journals (Sweden)

Marius Schmidt

2013-01-01

Full Text Available Time-resolved macromolecular crystallography unifies structure determination with chemical kinetics, since the structures of transient states and chemical and kinetic mechanisms can be determined simultaneously from the same data. To start a reaction in an enzyme, typically, an initially inactive substrate present in the crystal is activated. This has particular disadvantages that are circumvented when active substrate is directly provided by diffusion. However, then it is prohibitive to use macroscopic crystals because diffusion times become too long. With small micro- and nanocrystals diffusion times are adequately short for most enzymes and the reaction can be swiftly initiated. We demonstrate here that a time-resolved crystallographic experiment becomes feasible by mixing substrate with enzyme nanocrystals which are subsequently injected into the X-ray beam of a pulsed X-ray source.

The Goal of Adequate Nutrition: Can It Be Made Affordable, Sustainable, and Universal?

Directory of Open Access Journals (Sweden)

Ian McFarlane

2016-11-01

Full Text Available Until about 1900, large proportions of the world population endured hunger and poverty. The 20th century saw world population increase from 1.6 to 6.1 billion, accompanied and to some extent made possible by rapid improvements in health standards and food supply, with associated advances in agricultural and nutrition sciences. In this paper, I use the application of linear programming (LP in preparation of rations for farm animals to illustrate a method of calculating the lowest cost of a human diet selected from locally available food items, constrained to provide recommended levels of food energy and nutrients; then, to find a realistic minimum cost, I apply the further constraint that the main sources of food energy in the costed diet are weighted in proportion to the actual reported consumption of food items in that area. Worldwide variations in dietary preferences raise the issue as to the sustainability of popular dietary regimes, and the paper reviews the factors associated with satisfying requirements for adequate nutrition within those regimes. The ultimate physical constraints on food supply are described, together with the ways in which climate change may affect those constraints. During the 20th century, food supply increased sufficiently in most areas to keep pace with the rapid increase in world population. Many challenges will need to be overcome if food supply is to continue to meet demand, and those challenges are made more severe by rising expectations of quality of life in the developing world, as well as by the impacts of climate change on agriculture and aquaculture.

Pregnancy complications are one of the major public health concerns. One of the main causes of preventable complications is the absence of or inadequate provision of prenatal care. The present study was conducted to investigate whether Extended Parallel Process Model's constructs can predict the utilization of prenatal care services. The present longitudinal prospective study was conducted on 192 pregnant women selected through the multi-stage sampling of health facilities in Qeshm, Hormozgan province, from April to June 2015. Participants were followed up from the first half of pregnancy until their childbirth to assess adequate or inadequate/non-utilization of prenatal care services. Data were collected using the structured Risk Behavior Diagnosis Scale. The analysis of the data was carried out in SPSS-22 using one-way ANOVA, linear regression and logistic regression analysis. The level of significance was set at 0.05. Totally, 178 pregnant women with a mean age of 25.31±5.42 completed the study. Perceived self-efficacy (OR=25.23; Pprenatal care. Husband's occupation in the labor market (OR=0.43; P=0.02), unwanted pregnancy (OR=0.352; Pcare for the minors or elderly at home (OR=0.35; P=0.045) were associated with lower odds of receiving prenatal care. The model showed that when perceived efficacy of the prenatal care services overcame the perceived threat, the likelihood of prenatal care usage will increase. This study identified some modifiable factors associated with prenatal care usage by women, providing key targets for appropriate clinical interventions.

Hierarchical Meta-Learning in Time Series Forecasting for Improved Interference-Less Machine Learning

Full Text Available The importance of an interference-less machine learning scheme in time series prediction is crucial, as an oversight can have a negative cumulative effect, especially when predicting many steps ahead of the currently available data. The on-going research on noise elimination in time series forecasting has led to a successful approach of decomposing the data sequence into component trends to identify noise-inducing information. The empirical mode decomposition method separates the time series/signal into a set of intrinsic mode functions ranging from high to low frequencies, which can be summed up to reconstruct the original data. The usual assumption that random noises are only contained in the high-frequency component has been shown not to be the case, as observed in our previous findings. The results from that experiment reveal that noise can be present in a low frequency component, and this motivates the newly-proposed algorithm. Additionally, to prevent the erosion of periodic trends and patterns within the series, we perform the learning of local and global trends separately in a hierarchical manner which succeeds in detecting and eliminating short/long term noise. The algorithm is tested on four datasets from financial market data and physical science data. The simulation results are compared with the conventional and state-of-the-art approaches for time series machine learning, such as the non-linear autoregressive neural network and the long short-term memory recurrent neural network, respectively. Statistically significant performance gains are recorded when the meta-learning algorithm for noise reduction is used in combination with these artificial neural networks. For time series data which cannot be decomposed into meaningful trends, applying the moving average method to create meta-information for guiding the learning process is still better than the traditional approach. Therefore, this new approach is applicable to the forecasting

Prospective randomized studies and meta-analyses have shown that laparoscopic resection for colonic cancer is equivalent to open resection with respect to the oncological results and has short-term advantages in the early postoperative outcome. The aim of this study was to investigate whether laparoscopic colonic resection has become established as the standard in routine treatment. Data from the multicenter observational study "Quality assurance colonic cancer (primary tumor)" from the time period from 1 January 2009 to 21 December 2011 were evaluated with respect to the total proportion of laparoscopic colonic cancer resections and tumor localization and specifically for laparoscopic sigmoid colon cancer resections. A comparison between low and high volume clinics (< 30 versus ≥ 30 colonic cancer resections/year) was carried out. Laparoscopic colonic cancer resections were carried out in 12 % versus 21.4 % of low and high volume clinics, respectively (p < 0.001) with a significant increase for low volume clinics (from 8.0 % to 15.6 %, p < 0.001) and a constant proportion in high volume clinics (from 21.7 % to 21.1 %, p = 0.905). For sigmoid colon cancer laparoscopic resection was carried out in 49.7 % versus 47.6 % (p = 0.584). Differences were found between low volume and high volume clinics in the conversion rates (17.3 % versus 6.6 %, p < 0.001), the length of the resected portion (Ø 23.6 cm versus 36.0 cm, p < 0.001) and the lymph node yield (Ø n = 15.7 versus 18.2, p = 0.008). There were no differences between the two groups of clinics regarding postoperative morbidity and mortality. The postoperative morbidity and length of stay were significantly lower for laparoscopic sigmoid resection than for conventional sigmoid resection. The laparoscopic access route for colonic cancer resection is not the standard approach in the participating clinics. The laparoscopic access route has the highest proportion for sigmoid colon resection. The differences in the

Full Text Available The optimal physical, chemical and nutritional properties of natural lipids depend on the structure and composition of triacylglycerols. However, they are not always mutually compatible. Lipid modification is a good way to give them specific functionalities, increase their oxidative stability, or improve their nutritional value. As such, chemical and enzymatic interesterification may be used to modify them and produce structured lipids. In accordance, the aim of this study is to compare chemical and enzymatic interesterifi cation of binary blends of fully hydrogenated soybean oil and walnut oil, using sodium methoxide or Lipozyme TL IM, respectively, to produce a fat base with adequate nutritional and physical characteristics. Three different mass ratios of fully hydrogenated soybean oil and walnut oil blends (20:80, 40:60 and 60:40 were interesterified and evaluated. Total interesterification was determined by the stabilization of the solid fat content. Chemical reaction of the 20:80 blend was completed in 10 min and of the 40:60 and 60:40 blends in 15 min. Enzymatically interesterified blends were stabilized in 120 min at all of the mass ratios. Complete interesterification significantly reduced the solid fat content of the blends at any composition. Chemical and enzymatically interesterified fully hydrogenated blend of soybean and walnut oil at mass ratio of 40:60 showed the plastic curve of an all-purpose-type shortening rich in polyunsaturated fatty acids, with a high linolenic acid (C18:3n3 content and with zero trans-fatty acids.

Purpose: Correction for intrafraction prostate motion becomes important for hypofraction treatment of prostate cancer. The purpose of this study was to estimate an ideal planning margin to account for intrafraction prostate motion as a function of imaging and repositioning frequency in the absence of continuous prostate motion monitoring. Methods and Materials: For 31 patients receiving intensity modulated radiation therapy treatment, prostate positions sampled at 10 Hz during treatment using the Calypso system were analyzed. Using these data, we simulated multiple, less frequent imaging protocols, including intervals of every 10, 15, 20, 30, 45, 60, 90, 120, 180, and 240 seconds. For each imaging protocol, the prostate displacement at the imaging time was corrected by subtracting prostate shifts from the subsequent displacements in that fraction. Furthermore, we conducted a principal component analysis to quantify the direction of prostate motion. Results: Averaging histograms of every 240 and 60 seconds for all patients, vector displacements of the prostate were, respectively, within 3 and 2 mm for 95% of the treatment time. A vector margin of 1 mm achieved 91.2% coverage of the prostate with 30 second imaging. The principal component analysis for all fractions showed the largest variance in prostate position in the midsagittal plane at 54° from the anterior direction, indicating that anterosuperior to inferoposterior is the direction of greatest motion. The smallest prostate motion is in the left-right direction. Conclusions: The magnitudes of intrafraction prostate motion along the superior-inferior and anterior-posterior directions are comparable, and the smallest motion is in the left-right direction. In the absence of continuous prostate motion monitoring, and under ideal circumstances, 1-, 2-, and 3-mm vector planning margins require a respective imaging frequency of every 15, 60, and 240 to account for intrafraction prostate motion while achieving

Adequate anticoagulation, measured using activated clotting time (ACT), is important during vascular and cardiac surgeries. Unfractionated heparin is the most common anticoagulant used. The purpose of this analysis was to compare the i-STAT ACT (iACT) to the Hemochron ACT (hACT), both of which were then compared to anti-factor Xa (anti-Xa) assay, a representation of heparin level and activity. Prospective study. Tertiary care cardiovascular center. Eleven consecutive elective adult cardiac surgical patients. Prior to cardiopulmonary bypass, ACTs were measured using i-STAT and Hemochron technologies and compared to each other and to anti-Xa assay prior to and during a cumulative administration of heparin. Data were compared using bias analyses. Heparin (300 U/kg) was administered in quarterly doses. Coagulation labs were collected prior to and 3 minutes after each quarterly dose of heparin. The baseline ACTs for i-STAT and Hemochron were 147 and 142 seconds, respectively. A significant association was found between iACT and hACT (p = 0.002). The iACT measurements underestimated hACT at ACT levels >180 seconds or anti-Xa levels >0.75 U/mL. No significant difference was found between ACT data at anti-Xa levels 0.75 U/mL.

2006-06-01

Full Text Available Abstract Background A low yield of lymph nodes (LN in abdominoperineal resection (APR specimen has been associated with preoperative radiation therapy (XRT in population-based studies, which may preclude adequate staging of anorectal carcinomas. We hypothesized that the number of LN retrieved in APR specimen was correlated with the dose and the timing of pelvic irradiation. Patients and methods We performed a retrospective study of 102 patients who underwent APR in a single institution between 1980 and 2004. Pathological reports were reviewed and the number of lymph nodes retrieved in APR specimens was correlated with: 1 Preoperative radiation; 2 Dose of pelvic irradiation; and 3 Time interval between the end of XRT and surgery. Results There were 61 men and 41 women, with a median age of 66 (range 25–89 years. There were 12 patients operated for squamous cell carcinoma of the anal canal (SCCA and 90 for rectal cancer. 83% and 46% of patients with anal and rectal cancer respectively underwent radical/neoadjuvant radiotherapy. The mean ± SD number of LN in APR specimen was 9.2 ± 5.9. The mean number of LN in APR specimen was significantly lower in patients who underwent preoperative XRT (8 ± 5.5 vs. 10.5 ± 6.1, Mann-Whitney U test, p = 0.02. The mean number of LN was not significantly different after XRT in patients with SCCA than in patients with rectal cancer (6.2 ± 5.3 vs. 7.8 ± 5.3, p = 0.33. Finally, there was an inverse correlation between the yield of LN and the time elapsed between XRT and surgery (linear regression coefficient r = -0.32, p = 0.03. Conclusion Our data indicate that: 1 radiation therapy affects the yield of LN retrieval in APR specimen; 2 this impact is time-dependent. These findings have important implications with regard to anatomic-pathological staging of anal and rectal cancers and subsequent decision-making regarding adjuvant chemotherapy.

The cerium fluoride (CeF 3 ) is a kind of new fast time response inorganic scintillator. The physical characteristics of CeF 3 are well suitable for detection of domestic pulse γ-rays. The time response of detector composed by phototube with CeF 3 are measured by use of the pulse radiation source with rise time about 0.8 ns, and FWHM time 1.5-2.2 ns. Experiment results show that the rise time is less than 2 ns, FWHM time is about 10 ns, fall time is about 60 ns, average decay time constant is 20-30 ns, respectively for CeF 3

photons on the light sensor could be determined with sub-nanosecond precision. Embedded in a custom calibration and analysis framework, this allows for a precise study of shower timing on the nanosecond level. The T3B experiment could prove an increased contribution of the delayed shower component in tungsten with respect to steel via a detailed study of the time distribution of energy depositions. In addition, it is observed that the relative importance of late energy depositions increases with radial distance from the shower axis. This increase is substantially more pronounced in tungsten with respect to steel. It could be shown that the standard hadronic shower model QGSPBERT, used for shower simulations at the LHC as well as for most CLIC physics studies, overestimates the delayed shower evolution systematically, while high precision extensions using precise neutron tracking models can reproduce the shower timing adequately. No significant difference in the delayed shower contribution was observed for different particle energies in a range between 60 GeV and 180 GeV.

Abstract Platelet function can be quantitatively assessed by specific assays such as light-transmission aggregometry, multiple-electrode aggregometry measuring the response to adenosine diphosphate (ADP), arachidonic acid, collagen, and thrombin-receptor activating peptide and viscoelastic tests such as rotational thromboelastometry (ROTEM). The task of extracting meaningful statistical and clinical information from high-dimensional data spaces in temporal multivariate clinical data represented in multivariate time series is complex. Building insightful visualizations for multivariate time series demands adequate usage of normalization techniques. In this article, various methods for data normalization (z-transformation, range transformation, proportion transformation, and interquartile range) are presented and visualized discussing the most suited approach for platelet function data series. Normalization was calculated per assay (test) for all time points and per time point for all tests. Interquartile range, range transformation, and z-transformation demonstrated the correlation as calculated by the Spearman correlation test, when normalized per assay (test) for all time points. When normalizing per time point for all tests, no correlation could be abstracted from the charts as was the case when using all data as 1 dataset for normalization. PMID:27428217

Recurrence Density Enhanced Complex Networks for Nonlinear Time Series Analysis

Costa, Diego G. De B.; Reis, Barbara M. Da F.; Zou, Yong; Quiles, Marcos G.; Macau, Elbert E. N.

We introduce a new method, which is entitled Recurrence Density Enhanced Complex Network (RDE-CN), to properly analyze nonlinear time series. Our method first transforms a recurrence plot into a figure of a reduced number of points yet preserving the main and fundamental recurrence properties of the original plot. This resulting figure is then reinterpreted as a complex network, which is further characterized by network statistical measures. We illustrate the computational power of RDE-CN approach by time series by both the logistic map and experimental fluid flows, which show that our method distinguishes different dynamics sufficiently well as the traditional recurrence analysis. Therefore, the proposed methodology characterizes the recurrence matrix adequately, while using a reduced set of points from the original recurrence plots.

A novel approach to first-level hardware triggering in the LHC experiments has been studied and a prototype system built. Calorimeter trigger primitive data ( {approx} 5 Tb/s) are re-organised and time-multiplexed so that a single processing node (FPGA) may access the data corresponding to the entire detector for a given bunch crossing. This provides maximal flexibility in the construction of new trigger algorithms, which will be an important factor in ensuring adequate trigger performance at the very high levels of background expected at the upgraded LHC. A test system that incorporates all the key technologies for a final system and demonstrates the time-multiplexing and algorithm performance is presented.

Teaching ethics: when respect for autonomy and cultural sensitivity collide.

Science.gov (United States)

Minkoff, Howard

2014-04-01

Respect for autonomy is a key ethical principle. However, in some cultures other moral domains such as community (emphasizing the importance of family roles) and sanctity (emphasizing the sacred and the spiritual side of human nature) hold equal value. Thus, an American physician may sometimes perceive a conflict between the desire to practice ethically and the wish to be sensitive to the mores of other cultures. For example, a woman may appear to be making what the physician thinks is a bad clinical choice because her spouse is speaking on her behalf. That physician may find it difficult to reconcile the sense that the patient had not exercised freely her autonomy with the desire to be culturally sensitive. In this article, the means by which a physician can reconcile respect for other cultures with respect for autonomy is explored. The question of whether physicians must always defer to patients' requests solely because they are couched in the language of cultural sensitivity is also addressed. Copyright © 2014 Mosby, Inc.

Paraphyly changes understanding of timing and tempo of diversification in subtribe Hakeinae (Proteaceae), a giant Australian plant radiation.

Mast, Austin R; Olde, Peter M; Makinson, Robert O; Jones, Eric; Kubes, Amanda; Miller, Eliot T; Weston, Peter H

Subtribe Hakeinae (526 spp.) represents a large Australian plant radiation central to our understanding of that flora's evolution and ecology. It contains Grevillea-the third largest plant genus in Australia and a group inferred to have among the highest diversification rates in the angiosperms. However, we lack a robust phylogenetic framework for understanding subtribe Hakeinae and recognize that Grevillea lacks an unambiguous synapomorphy supporting its monophyly. We used four plastid and one nuclear DNA region from a taxonomically even sampling of a third of the species to infer a time-calibrated phylogeny of Hakeinae and absolute diversification rates of major clades. We developed the R package addTaxa to add unsampled taxa to the tree for diversification rate inference. Grevillea is paraphyletic with respect to Hakea and Finschia. Under most parameter combinations, Hakea contains the major clade with the highest diversification rate in Hakeinae, rather than Grevillea. The crown age of the Grevillea+Hakea+Finschia crown group is about double that of prior estimates. We demonstrate that the paraphyly of Grevillea considerably enlarges the number of Australian descendants from its most recent common ancestor but has also misled investigators who considered a single operational taxonomic unit as adequate to represent the genus for inferences of diversification rate and timing. Our time-calibrated phylogeny can form the basis of future evolutionary, comparative ecology, and biogeography studies involving this large Australian plant radiation, as well as nomenclatural changes. © 2015 Botanical Society of America.

1998-01-01

Laboratory applications for the analysis of PCBs (polychlorinated biphenyls) in environmental matrices such as soil/sediment/sludge and oil/waste oil were evaluated for potential reduction in waste, source reduction, and alternative techniques for final determination. As a consequence, new procedures were studied for solvent substitution, miniaturization of extraction and cleanups, minimization of reagent consumption, reduction of cost per analysis, and reduction of time. These new procedures provide adequate data that meet all the performance requirements for the determination of PCBs. Use of the new procedures reduced costs for all sample preparation techniques. Time and cost were also reduced by combining the new sample preparation procedures with the power of fast gas chromatography. Separation of Aroclor 1254 was achieved in less than 6 min by using DB-1 and SPB-608 columns. With the greatly shortened run times, reproducibility can be tested quickly and consequently with low cost. With performance-based methodology, the applications presented here can be applied now, without waiting for regulatory approval

Interactive real-time nuclear plant simulations on a UNIX based supercomputer

International Nuclear Information System (INIS)

Behling, S.R.

1990-01-01

Interactive real-time nuclear plant simulations are critically important to train nuclear power plant engineers and operators. In addition, real-time simulations can be used to test the validity and timing of plant technical specifications and operational procedures. To accurately and confidently simulate a nuclear power plant transient in real-time, sufficient computer resources must be available. Since some important transients cannot be simulated using preprogrammed responses or non-physical models, commonly used simulation techniques may not be adequate. However, the power of a supercomputer allows one to accurately calculate the behavior of nuclear power plants even during very complex transients. Many of these transients can be calculated in real-time or quicker on the fastest supercomputers. The concept of running interactive real-time nuclear power plant transients on a supercomputer has been tested. This paper describes the architecture of the simulation program, the techniques used to establish real-time synchronization, and other issues related to the use of supercomputers in a new and potentially very important area.

2018-10-01

Lupine is widely used as an ingredient in diverse food products, but it is also a source of allergens. This work aimed at proposing a method to detect/quantify lupine as an allergen in processed foods based on a normalised real-time PCR assay targeting the Lup a 4 allergen-encoding gene of Lupinus albus. Sensitivities down to 0.0005%, 0.01% and 0.05% (w/w) of lupine in rice flour, wheat flour and bread, respectively, and 1 pg of L. albus DNA were obtained, with adequate real-time PCR performance parameters using the ΔCt method. Both food matrix and processing affected negatively the quantitative performance of the assay. The method was successfully validated with blind samples and applied to processed foods. Lupine was estimated between 4.12 and 22.9% in foods, with some results suggesting the common practice of precautionary labelling. In this work, useful and effective tools were proposed for the detection/quantification of lupine in food products. Copyright © 2018 Elsevier Ltd. All rights reserved.

Fluoroscopic radiation exposure: are we protecting ourselves adequately?

Science.gov (United States)

Hoffler, C Edward; Ilyas, Asif M

2015-05-06

While traditional intraoperative fluoroscopy protection relies on thyroid shields and aprons, recent data suggest that the surgeon's eyes and hands receive more exposure than previously appreciated. Using a distal radial fracture surgery model, we examined (1) radiation exposure to the eyes, thyroid, chest, groin, and hands of a surgeon mannequin; (2) the degree to which shielding equipment can decrease exposure; and (3) how exposure varies with fluoroscopy unit size. An anthropomorphic model was fit with radiation-attenuating glasses, a thyroid shield, an apron, and gloves. "Exposed" thermoluminescent dosimeters overlaid the protective equipment at the eyes, thyroid, chest, groin, and index finger while "shielded" dosimeters were placed beneath the protective equipment. Fluoroscopy position and settings were standardized. The mini-c-arm milliampere-seconds were fixed based on the selection of the kilovolt peak (kVp). Three mini and three standard c-arms scanned a model of the patient's wrist continuously for fifteen minutes each. Ten dosimeter exposures were recorded for each c-arm. Hand exposure averaged 31 μSv/min (range, 22 to 48 μSv/min), which was 13.0 times higher than the other recorded exposures. Eye exposure averaged 4 μSv/min, 2.2 times higher than the mean thyroid, chest, and groin exposure. Gloves reduced hand exposure by 69.4%. Glasses decreased eye exposure by 65.6%. There was no significant difference in exposure between mini and standard fluoroscopy. Surgeons' hands receive the most radiation exposure during distal radial plate fixation under fluoroscopy. There was a small but insignificant difference in mean exposure between standard fluoroscopy and mini-fluoroscopy, but some standard units resulted in lower exposure than some mini-units. On the basis of these findings, we recommend routine protective equipment to mitigate exposure to surgeons' hands and eyes, in addition to the thyroid, chest, and groin, during fluoroscopy procedures

2018-01-01

Post-marketing surveillance (PMS) was conducted to assess the safety and effectiveness of tacrolimus (TAC) add-on therapy for patients with rheumatoid arthritis (RA) and an inadequate response to biological disease-modifying anti-rheumatic drugs (DMARDs). Patients with RA from 180 medical sites across Japan were registered centrally with an electronic investigation system. The observational period was 24 weeks from the first day of TAC administration concomitantly with biological DMARDs. Safety and effectiveness populations included 624 and 566 patients, respectively. Patients were predominantly female (81.1%), with a mean age of 61.9 years. Overall, 125 adverse drug reactions (ADRs) occurred in 94 patients (15.1%), and 15 serious ADRs occurred in 11 patients (1.8%). These incidences were lower compared with previously reported incidences after TAC treatment in PMS, and all of the observed ADRs were already known. A statistically significant improvement was observed in the primary effectiveness variable of Simplified Disease Activity Index after TAC treatment; 62.7% of patients achieved remission or low disease activity at week 24. TAC is well tolerated and effective when used as an add-on to biological DMARDs in Japanese patients with RA who do not achieve an adequate response to biological DMARDs in a real-world clinical setting.

Time Dependent Quantum Mechanics

OpenAIRE

Morrison, Peter G.

2012-01-01

We present a systematic method for dealing with time dependent quantum dynamics, based on the quantum brachistochrone and matrix mechanics. We derive the explicit time dependence of the Hamiltonian operator for a number of constrained finite systems from this formalism. Once this has been achieved we go on to calculate the wavevector as a function of time, in order to demonstrate the use of matrix methods with respect to several concrete examples. Interesting results are derived for elliptic ...

Fast timing readout for silicon strip detectors

International Nuclear Information System (INIS)

Jhingan, A.; Saneesh, N.; Kumar, M.

2016-01-01

The development and performance of a 16 channel hybrid fast timing amplifier (FTA), for extracting timing information from silicon strip detectors (SSD), is described. The FTA will be used in a time of flight (TOF) measurement, in which one SSD is used to obtain the ion velocity (A) as well as the energy information of a scattered particle. The TOF information with a thin transmission SSD, acting as ΔE detector (Z) in a detector telescope, will provide a unique detection system for the identification of reaction products in the slowed down beam campaign of low energy branch (LEB) at NUSTAR-FAIR. Such a system will also provide large solid angle coverage with ~ 100% detection efficiency, and adequate segmentation for angular information. A good timing resolution (≤ 100 ps) enables to have shorter flight paths, thus a closely packed 4π array should be feasible. Preamplifiers for energy readout in SSD are easily available. A major constraint with SSDs is the missing high density multichannel preamplifiers which can provide both fast timing as well as energy. Provision of both timing and energy processing, generally makes circuit bulky, with higher power consumption, which may not be suitable in SSD arrays. In case of DSSSD, the problem was overcome by using timing from one side and energy from the other side. A custom designed 16 channel FTA has been developed for DSSSD design W from Micron Semiconductors, UK

The SOFIA experiment, which will be held at GSI (Darmstadt (Germany)) will allow to completely determine the mass and charge numbers of fragments produced in the fission reaction of radioactive actinides in reverse kinematics. Therefore, a dedicated setup has been developed for the Time of Flight measurement of relativistic heavy ions. The studies, which led to the choice of the adequate plastic scintillators and photomultipliers, are presented. Tests have been undertaken with the ELSA laser and electron beam facility. They shown that a suitable choice would be EJ-232 plastic scintillator for the ToF wall and EJ-232Q for the start detector and Hamamatsu H6533 and H10580 photomultipliers. This was confirmed by two test experiments realized at GSI with relativistic heavy ion beam ( 56 Fe and 238 U), where a time of flight resolution better than 20 ps FWHM was reached. (authors)

Detection and modelling of time-dependent QTL in animal populations

DEFF Research Database (Denmark)

Lund, Mogens S; Sørensen, Peter; Madsen, Per

2008-01-01

A longitudinal approach is proposed to map QTL affecting function-valued traits and to estimate their effect over time. The method is based on fitting mixed random regression models. The QTL allelic effects are modelled with random coefficient parametric curves and using a gametic relationship...... matrix. A simulation study was conducted in order to assess the ability of the approach to fit different patterns of QTL over time. It was found that this longitudinal approach was able to adequately fit the simulated variance functions and considerably improved the power of detection of time-varying QTL...... effects compared to the traditional univariate model. This was confirmed by an analysis of protein yield data in dairy cattle, where the model was able to detect QTL with high effect either at the beginning or the end of the lactation, that were not detected with a simple 305 day model....

Poster - Thurs Eve-16: Just-in-time tomography (JiTT).

Science.gov (United States)

Pang, G; Rowlands, J A

2008-07-01

Soft-tissue target motion is one of the main concerns in high-precision radiation therapy. Cone beam computed tomography (CBCT) has been developed recently to image soft-tissue targets in the treatment room for image-guided radiation therapy. However, due to its relatively long image acquisition time the CBCT approach cannot provide images of the target at the instant of the treatment and thus is not adequate for imaging targets with intrafraction motion. In this work, a new concept for image-guided radiation therapy- just-in-time tomography (JiTT) - is introduced. Differing from CBCT, JiTT takes much less time to generate the needed tomographical, beam's-eye-view images of the treatment target at the right moment to guide the radiation therapy treatment. A system to achieve JiTT is proposed and its feasibility is investigated. Research supported by Siemens. © 2008 American Association of Physicists in Medicine.

Light water reactor sequence timing: its significance to probabilistic safety assessment modeling

Bley, D.C.; Buttemer, D.R.; Stetkar, J.W.

1988-01-01

This paper examines event sequence timing in light water reactor plants from the viewpoint of probabilistic safety assessment (PSA). The analytical basis for the ideas presented here come primarily from the authors' work in support of more than 20 PSA studies over the past several years. Timing effects are important for establishing success criteria for support and safety system response and for identifying the time available for operator recovery actions. The principal results of this paper are as follows: 1. Analysis of event sequence timing is necessary for meaningful probabilistic safety assessment - both the success criteria for systems performance and the probability of recovery are tightly linked to sequence timing. 2. Simple engineering analyses based on first principles are often sufficient to provide adequate resolution of the time available for recovery of PSA scenarios. Only those parameters that influence sequence timing and its variability and uncertainty need be examined. 3. Time available for recovery is the basic criterion for evaluation of human performance, whether time is an explicit parameter of the operator actions analysis or not. (author)

On the validity of travel-time based nonlinear bioreactive transport models in steady-state flow.

Sanz-Prat, Alicia; Lu, Chuanhe; Finkel, Michael; Cirpka, Olaf A

2015-01-01

Travel-time based models simplify the description of reactive transport by replacing the spatial coordinates with the groundwater travel time, posing a quasi one-dimensional (1-D) problem and potentially rendering the determination of multidimensional parameter fields unnecessary. While the approach is exact for strictly advective transport in steady-state flow if the reactive properties of the porous medium are uniform, its validity is unclear when local-scale mixing affects the reactive behavior. We compare a two-dimensional (2-D), spatially explicit, bioreactive, advective-dispersive transport model, considered as "virtual truth", with three 1-D travel-time based models which differ in the conceptualization of longitudinal dispersion: (i) neglecting dispersive mixing altogether, (ii) introducing a local-scale longitudinal dispersivity constant in time and space, and (iii) using an effective longitudinal dispersivity that increases linearly with distance. The reactive system considers biodegradation of dissolved organic carbon, which is introduced into a hydraulically heterogeneous domain together with oxygen and nitrate. Aerobic and denitrifying bacteria use the energy of the microbial transformations for growth. We analyze six scenarios differing in the variance of log-hydraulic conductivity and in the inflow boundary conditions (constant versus time-varying concentration). The concentrations of the 1-D models are mapped to the 2-D domain by means of the kinematic (for case i), and mean groundwater age (for cases ii & iii), respectively. The comparison between concentrations of the "virtual truth" and the 1-D approaches indicates extremely good agreement when using an effective, linearly increasing longitudinal dispersivity in the majority of the scenarios, while the other two 1-D approaches reproduce at least the concentration tendencies well. At late times, all 1-D models give valid approximations of two-dimensional transport. We conclude that the

Time-causal decomposition of geomagnetic time series into secular variation, solar quiet, and disturbance signals

Science.gov (United States)

Rigler, E. Joshua

2017-04-26

A theoretical basis and prototype numerical algorithm are provided that decompose regular time series of geomagnetic observations into three components: secular variation; solar quiet, and disturbance. Respectively, these three components correspond roughly to slow changes in the Earth’s internal magnetic field, periodic daily variations caused by quasi-stationary (with respect to the sun) electrical current systems in the Earth’s magnetosphere, and episodic perturbations to the geomagnetic baseline that are typically driven by fluctuations in a solar wind that interacts electromagnetically with the Earth’s magnetosphere. In contrast to similar algorithms applied to geomagnetic data in the past, this one addresses the issue of real time data acquisition directly by applying a time-causal, exponential smoother with “seasonal corrections” to the data as soon as they become available.

Why should we respect the privacy of donors of biological material?

Science.gov (United States)

Tännsjö, Torbjörn

2011-02-01

Why should we respect the privacy of donors of biological material? The question is answered in the present article in general philosophical terms from the point of view of an ethics of honour, a libertarian theory of rights, a view of respect for privacy based on the idea that autonomy is of value in itself, and utilitarianism respectively. For different reasons the ethics of honour and the idea of the value of autonomy are set to one side. It surfaces that the moral rights theory and utilitarianism present conflicting answers to the question. The main thrust of the argument is that there is no way of finding an overlapping consensus, so politicians have to take decisions that are bound to be controversial in that they can be questioned on reasonable philosophical grounds.

Back-end fuel cycle efficiencies with respect to improved uranium utilization

International Nuclear Information System (INIS)

Kuczera, B.; Hennies, H.H.

1983-01-01

The world-wide nuclear power plant (NPP) capacity is at present 160 GW(e). If one adds the power stations under construction and ordered, a plant capacity of approximately 480 GW(e) is obtained for 1990, with the share of LWRs making up more than 80%. A modern LWR consumes in the open fuel cycle about 4400 metric tonnes of natural uranium per GW(e), assuming a lifetime of 30 years and a load factor of 70%. Considering the natural uranium reserves known at present and exploitable under economic conditions, it can be conveniently estimated that, with the present NPP capacity extension perspective, the natural uranium resources may be exhausted in a few decades. This trend can be counteracted in a flexible manner by various approaches in fuel cycle technology and strategy: (i) by steady further development of the established LWR technology the uranium consumption can be reduced by about 15%; (ii) closing the nuclear fuel cycle on the basis of LWRs (i.e. thermal uranium and plutonium recycling) implies up to 40% savings in natural uranium consumption; (iii) more recent considerations include the advanced pressurized water reactor (APWR). The APWR combines the proven PWR technology with a newly developed tight lattice core with greatly improved conversion characteristics (conversion ratio = 0.90 to 0.95). In terms of uranium utilization, the APWR has an efficiency three to five times higher than a PWR; (iv) Commercial introduction of FBR systems results in an optimal utilization of uranium which, at the same time, guarantees the supply of nuclear fuel well beyond the present century. For a corresponding transition period an energy supply system can be conceived which relies essentially on extended back-end fuel cycle capacities. These would facilitate a symbiosis of PWR, APWR and FBR, characterized by high flexibility with respect to long-term developments on the energy market. (author)

Healthcare Costs Associated with an Adequate Intake of Sugars, Salt and Saturated Fat in Germany: A Health Econometrical Analysis.

Directory of Open Access Journals (Sweden)

Toni Meier

Full Text Available Non-communicable diseases (NCDs represent not only the major driver for quality-restricted and lost life years; NCDs and their related medical treatment costs also pose a substantial economic burden on healthcare and intra-generational tax distribution systems. The main objective of this study was therefore to quantify the economic burden of unbalanced nutrition in Germany--in particular the effects of an excessive consumption of fat, salt and sugar--and to examine different reduction scenarios on this basis. In this study, the avoidable direct cost savings in the German healthcare system attributable to an adequate intake of saturated fatty acids (SFA, salt and sugar (mono- & disaccharides, MDS were calculated. To this end, disease-specific healthcare cost data from the official Federal Health Monitoring for the years 2002-2008 and disease-related risk factors, obtained by thoroughly searching the literature, were used. A total of 22 clinical endpoints with 48 risk-outcome pairs were considered. Direct healthcare costs attributable to an unbalanced intake of fat, salt and sugar are calculated to be 16.8 billion EUR (CI95%: 6.3-24.1 billion EUR in the year 2008, which represents 7% (CI95% 2%-10% of the total treatment costs in Germany (254 billion EUR. This is equal to 205 EUR per person annually. The excessive consumption of sugar poses the highest burden, at 8.6 billion EUR (CI95%: 3.0-12.1; salt ranks 2nd at 5.3 billion EUR (CI95%: 3.2-7.3 and saturated fat ranks 3rd at 2.9 billion EUR (CI95%: 32 million-4.7 billion. Predicted direct healthcare cost savings by means of a balanced intake of sugars, salt and saturated fat are substantial. However, as this study solely considered direct medical treatment costs regarding an adequate consumption of fat, salt and sugars, the actual societal and economic gains, resulting both from direct and indirect cost savings, may easily exceed 16.8 billion EUR.

median follow-up of 3 years for this cohort (range: 1 to 5 years). This process was repeated five times for five random samples of seven cohorts each. Biochemical failure was calculated according to the Consensus Panel definition. Results: In the first analysis, significantly different rates of biochemical control (varying by 6-21%) were calculated for the same actuarial year chosen for analysis depending only upon the length of follow-up used. For example, the 3-year actuarial rate of biochemical control (BC) varied from 71% when calculated with 3 years of follow-up versus 50.4% with 7 years (p < 0.01). These differences in actuarial rates of BC were observed in all subsets of patients analyzed (e.g., PSA < 10, Gleason ≤ 6, n = 132, p < 0.001; PSA < 10, Gleason ≥ 7, n = 33, p = 0.03; PSA ≥ 10, Gleason ≤ 6, n = 109, p < 0.001; and PSA ≥ 10, Gleason ≥ 7, n = 72, p = 0.002). The absolute magnitude of the difference in actuarial rates of BC was greatest during years 2 (range 18-30%), 3 (range 16-25%), and 4 (range 15-24%) after treatment. In the second analysis using median PSA follow-ups (as defined above), statistically significant differences in actuarial rates of BC were again observed. For example, the 3-year actuarial rate of BC varied from 74.8% with a median follow-up of 2 years versus 49.2% with a median follow-up of 6 years. These dramatic differences in BC were still observed beyond 5 years. Conclusion: When the ASTRO Consensus Panel definition of BF is used to calculate treatment success with external beam RT for prostate cancer, adequate follow-up is critical. Depending upon the length of time after treatment, significantly different rates of BC (varying by 15% to 30%) can be calculated for the same time interval chosen for analysis. These results suggest that data should only be reported if the length of follow-up extends at least beyond the time point at which actuarial results are examined for the majority of patients

1.1 This test method determines the degree of linearity of a photovoltaic device parameter with respect to a test parameter, for example, short-circuit current with respect to irradiance. 1.2 The linearity determined by this test method applies only at the time of testing, and implies no past or future performance level. 1.3 This test method applies only to non-concentrator terrestrial photovoltaic devices. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Use of a large time-compensated scintillation detector in neutron time-of-flight measurements

International Nuclear Information System (INIS)

Goodman, C.D.

1979-01-01

A scintillator for neutron time-of-flight measurements is positioned at a desired angle with respect to the neutron beam, and as a function of the energy thereof, such that the sum of the transit times of the neutrons and photons in the scintillator are substantially independent of the points of scintillations within the scintillator. Extrapolated zero timing is employed rather than the usual constant fraction timing. As a result, a substantially larger scintillator can be employed that substantially increases the data rate and shortens the experiment time. 3 claims

The doormat effect: when forgiving erodes self-respect and self-concept clarity.

Science.gov (United States)

Luchies, Laura B; Finkel, Eli J; McNulty, James K; Kumashiro, Madoka

2010-05-01

We build on principles from interdependence theory and evolutionary psychology to propose that forgiving bolsters one's self-respect and self-concept clarity if the perpetrator has acted in a manner that signals that the victim will be safe and valued in a continued relationship with the perpetrator but that forgiving diminishes one's self-respect and self-concept clarity if the perpetrator has not. Study 1 employed a longitudinal design to demonstrate that the association of marital forgiveness with trajectories of self-respect over the first 5 years of marriage depends on the spouse's dispositional tendency to indicate that the partner will be safe and valued (i.e., agreeableness). Studies 2 and 3 employed experimental procedures to demonstrate that the effects of forgiveness on self-respect and self-concept clarity depend on the perpetrator's event-specific indication that the victim will be safe and valued (i.e., amends). Study 4 employed a longitudinal design to demonstrate that the association of forgiveness with subsequent self-respect and self-concept clarity similarly depends on the extent to which the perpetrator has made amends. These studies reveal that, under some circumstances, forgiveness negatively impacts the self. 2010 APA, all rights reserved

Sensor response time monitoring using noise analysis

International Nuclear Information System (INIS)

Hashemian, H.M.; Thie, J.A.; Upadhyaya, B.R.; Holbert, K.E.

1988-01-01

Random noise techniques in nuclear power plants have been developed for system surveillance and for analysis of reactor core dynamics. The noise signals also contain information about sensor dynamics, and this can be extracted using frequency, amplitude and time domain analyses. Even though noise analysis has been used for sensor response time testing in some nuclear power plants, an adequate validation of this method has never been carried out. This paper presents the results of limited work recently performed to examine the validity of the noise analysis for sensor response time testing in nuclear power plants. The conclusion is that noise analysis has the potential for detecting gross changes in sensor response but it cannot be used for reliable measurement of response time until more laboratory and field experience is accumulated. The method is more advantageous for testing pressure sensors than it is for temperature sensors. This is because: 1) for temperature sensors, a method called Loop Current Step Response test is available which is quantitatively more exact than noise analysis, 2) no method currently exists for on-line testing of pressure transmitters other than the Power-Interrupt test which is applicable only to force balance pressure transmitters, and 3) pressure sensor response time is affected by sensing line degradation which is inherently taken into account by testing with noise analysis.

The cerebellar hypothesis of dyslexia posits that cerebellar deficits are associated with reading disabilities and may explain why some individuals with reading disabilities fail to respond to reading interventions. We tested these hypotheses in a sample of children who participated in a grade 1 reading intervention study (n = 174) and a group of typically achieving children (n = 62). At posttest, children were classified as adequately responding to the intervention (n = 82), inadequately responding with decoding and fluency deficits (n = 36), or inadequately responding with only fluency deficits (n = 56). Based on the Bead Threading and Postural Stability subtests from the Dyslexia Screening Test-Junior, we found little evidence that assessments of cerebellar functions were associated with academic performance or responder status. In addition, we did not find evidence supporting the hypothesis that cerebellar deficits are more prominent for poor readers with "specific" reading disabilities (i.e., with discrepancies relative to IQ) than for poor readers with reading scores consistent with IQ. In contrast, measures of phonological awareness, rapid naming, and vocabulary were strongly associated with responder status and academic outcomes. These results add to accumulating evidence that fails to associate cerebellar functions with reading difficulties.

In Respect to the Cognitive Load Theory: Adjusting Instructional Guidance with Student Expertise.

Science.gov (United States)

Schilling, Jim

2017-01-01

The amount of guidance supplied by educators to students in allied health programs is a factor in student learning. According to the cognitive load theory of learning, without adequate instructional support, novice learners will be overwhelmed and unable to store information, while unnecessary guidance supplied to advanced students will cause extraneous cognitive load on the working memory system. Adjusting instructional guidance for students according to their level of expertise to minimize extraneous cognitive load and optimize working memory storage capacity will enhance learning effectiveness. Novice students presented with complex subject matter require significant guidance during the initial stages, using strategies such as worked examples. As students comprehend information, instructional guidance needs to gradually fade to avoid elevated extraneous cognitive load from the expertise reversal effect. An instructional strategy that utilizes a systemic (fixed) or adjustable (adaptive) tapering of guidance to students in allied health programs depending on their expertise will optimize learning capability.

Electricity and long term supply security. Search for power market respectful legal instruments

International Nuclear Information System (INIS)

Finon, D.; Pignon, V.

2006-01-01

This paper, also published in 'ISMEA Economie et Societe' Journal (Energy series 2006, no.10), deals with theoretical aspects of long term electricity supply security. Market prices and contractual arrangements on the physical and financial electricity markets do not allow to create sufficient incentives to invest in adequate capacity for guaranteeing the appropriate level of supply in every circumstance. The long term security of supply by capacity adequacy must be conceptualized as a collective good. Alternative solutions to reach capacity adequacy which have been adopted in different markets are successively considered: public procurement of strategic reserves, capacity payment, capacity obligation with exchangeable rights. Each one presents theoretical limits and practical drawbacks when implemented in complex markets. That brings out the interest of mechanism of centralized auctions for forward capacity contracts (or reliability options); it combines controls by quantity and by price while stabilizing investment in peak power plants and is compatible with energy and reserves markets, that is not the case of the three other instruments.

2018-01-01

Full Text Available Possible approaches to real-time order tracking are discussed. Two methods for real-time order tracking are developed and validated experimentally for the entire audible spectrum. An adaptive heterodyne filter bank is compared to a direct integral transform. The performance of both methods is adequate for usage in an active vibration control (AVC algorithm. Vold-Kalman filters are not suitable for AVC. The vibration data of three different planetary gearboxes is analyzed using order tracking. While some of the existing research could be reproduced, the data contradicts statements made by several authors. Lastly, the architecture of a novel AVC algorithm is sketched out.

A Robust Ultra-Low Voltage CPU Utilizing Timing-Error Prevention

Directory of Open Access Journals (Sweden)

Markus Hiienkari

2015-04-01

Full Text Available To minimize energy consumption of a digital circuit, logic can be operated at sub- or near-threshold voltage. Operation at this region is challenging due to device and environment variations, and resulting performance may not be adequate to all applications. This article presents two variants of a 32-bit RISC CPU targeted for near-threshold voltage. Both CPUs are placed on the same die and manufactured in 28 nm CMOS process. They employ timing-error prevention with clock stretching to enable operation with minimal safety margins while maximizing performance and energy efficiency at a given operating point. Measurements show minimum energy of 3.15 pJ/cyc at 400 mV, which corresponds to 39% energy saving compared to operation based on static signoff timing.

Purpose: Using real-time electromagnetic (EM) transponder tracking data recorded by the Calypso 4D Localization System, we report inter- and intrafractional target motion of the prostate bed, describe a strategy to evaluate treatment adequacy in postprostatectomy patients receiving intensity modulated radiation therapy (IMRT), and propose an adaptive workflow. Methods and Materials: Tracking data recorded by Calypso EM transponders was analyzed for postprostatectomy patients that underwent step-and-shoot IMRT. Rigid target motion parameters during beam delivery were calculated from recorded transponder positions in 16 patients with rigid transponder geometry. The delivered doses to the clinical target volume (CTV) were estimated from the planned dose matrix and the target motion for the first 3, 5, 10, and all fractions. Treatment adequacy was determined by comparing the delivered minimum dose (D{sub min}) with the planned D{sub min} to the CTV. Treatments were considered adequate if the delivered CTV D{sub min} is at least 95% of the planned CTV D{sub min}. Results: Translational target motion was minimal for all 16 patients (mean: 0.02 cm; range: −0.12 cm to 0.07 cm). Rotational motion was patient-specific, and maximum pitch, yaw, and roll were 12.2, 4.1, and 10.5°, respectively. We observed inadequate treatments in 5 patients. In these treatments, we observed greater target rotations along with large distances between the CTV centroid and transponder centroid. The treatment adequacy from the initial 10 fractions successfully predicted the overall adequacy in 4 of 5 inadequate treatments and 10 of 11 adequate treatments. Conclusion: Target rotational motion could cause underdosage to partial volume of the postprostatectomy targets. Our adaptive treatment strategy is applicable to post-prostatectomy patients receiving IMRT to evaluate and improve radiation therapy delivery.

Full Text Available Research purpose: Managers, when applying their leadership styles, are affected by some of their own traits. This article intends to compare the leadership styles of the managers of Zabol University of Medical Sciences with respect to Hersey and Blanchard model that was based on their biographical characteristics. Research design, approach and method: The research methodology is descriptive-causal and comparative. The data were collected from 300 individuals (124 female and 176 male participants. Main findings: No significant difference was observed between the directive, persuasive, participative and delegative leadership styles of male and female managers. However, there was a significant difference between the mean of the directive, persuasive, participative and delegative leadership styles of managers, considering their work experience, education level and field of study. Research limitations: The conservative atmosphere in university environments may affect the manager’s responses to the questionnaire; therefore, in the generalisation of the results, this issue should be taken into account. Practical implications: It is recommended to hold in-service courses for managers who have a lower education level or less work experience or have been graduated from the fields of study other than the Management major. It is also suggested to pay attention to the managers’ fields of study and managerial experiences at the time of employment. Contribution: This study enhances the quality of managers’ leadership style and consequently increases the productivity in university environments.

Emotional Experiences of Obese Women with Adequate Gestational Weight Variation: A Qualitative Study.

Débora Bicudo Faria-Schützer

Full Text Available As a result of the growth of the obese population, the number of obese women of fertile age has increased in the last few years. Obesity in pregnancy is related to greater levels of anxiety, depression and physical harm. However, pregnancy is an opportune moment for the intervention of health care professionals to address obesity. The objective of this study was to describe how obese pregnant women emotionally experience success in adequate weight control.Using a qualitative design that seeks to understand content in the field of health, the sample of subjects was deliberated, with thirteen obese pregnant women selected to participate in an individual interview. Data was analysed by inductive content analysis and includes complete transcription of the interviews, re-readings using suspended attention, categorization in discussion topics and the qualitative and inductive analysis of the content. The analysis revealed four categories, three of which show the trajectory of body care that obese women experience during pregnancy: 1 The obese pregnant woman starts to think about her body;2 The challenge of the diet for the obese pregnant woman; 3 The relation of the obese pregnant woman with the team of antenatal professionals. The fourth category reveals the origin of the motivation for the change: 4 The potentializing factors for change: the motivation of the obese woman while pregnant.During pregnancy, obese women are more in touch with themselves and with their emotional conflicts. Through the transformations of their bodies, women can start a more refined self-care process and experience of the body-mind unit. The fear for their own and their baby's life, due to the risks posed by obesity, appears to be a great potentializing factor for change. The relationship with the professionals of the health care team plays an important role in the motivational support of the obese pregnant woman.

The present work deals both with the theory and performance of a reverse-time-of-flight (RTOF) analyzer designed to analyze pulses emitted from a fourier chopper recently put into operation at the ETRR-1 reactor. The RTOF analyze was found to be adequate for use with pick up pulses from the fourier chopper which operates following a frequency window suitable for rotation rates from 0-9000 rpm; synchronically with neutron pulses from a {sup 6} Li glass detector set at time focusing geometry for scattering angle 20=90 degree. It was possible, with the present RTOF analyzer to obtain diffraction patterns at neutron wavelength range between 1 - 4 A within a resolution = 0.5%. 8 FIGS.

There are uncertain issues on the diagnostic methods of premature ejaculation (PE). The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria in diagnosing PE and the aim of this study is to carry out the Turkish validation of the PEDT and to evaluate its association with intravaginal ejaculatory latency time (IELT). A total of 94 patients with a self-reported complaint of PE and 88 men without PE were enrolled into the study and requested to complete the nine-item PEDT, which was translated into Turkish. The patients were also requested to measure IELT. All participants were requested to come for a second visit to assess the PEDT's retest reliability; data from 78 men in the PE group and 69 men in the control group were collected. The IELT data of 35 patients were also recorded. The mean age of the PE group and the control group were 39.4+/-9.7 (24-65) and 30.1+/-5.7 (20-56), respectively, (P=0.068). Among the patients in the PE group, 24 (68.5%) reported life-long PE, whereas 11 (31.5%) reported acquired PE. The geometric mean IELT of the PE group was 59.7+/-46.2 (6.5-197.7) s. The number of men reporting IELTs of 2 min were 20 (57.1%), 11 (31.5) and 4 (11.4%), respectively. The factor analysis assessment showed that the five-item combination (questions 1, 2, 3, 4 and 8) explained 74.4% of the variance, there were no other combinations that explained the variance more effectively. Cronbach's alpha score of five-item combination was calculated as 0.77, showing adequate internal consistency. The overall Cronbach's alpha score did not increase if any item combination was deleted. The test-retest correlation coefficients of each item were higher than 0.80 and the correlation coefficient of the total score was 0.90. The PEDT and IELT showed an adequate correlation (rho=0.44). As a conclusion, the validated five-item Turkish version of PEDT is a

Ion temperature measurement of indirectly-driven implosions using a geometry-compensated neutron time-of-flight detector

International Nuclear Information System (INIS)

Murphy, T.J.; Lerche, R.A.; Bennett, C.; Howe, G.

1994-05-01

A geometry-compensated neutron time-of-flight detector has been constructed and used on Nova to measure ion temperatures from indirectly-driven implosions with yields between 2.5 and 5 x 10 9 DD neutrons. The detector, which has an estimated response time of 250 ps, was located 150 cm from the targets. Due to the long decay time of the scintillator, the time-of-flight signal must be unfolded from the measured detector signal. Several methods for determining the width of the neutron energy spectrum from the data have been developed and give similar results. Scattered x rays continue to be a problem for low yield shots, but should be brought under control with adequate shielding

The architecture of a readout system is described which will be used in conjunction with the muon detector in the UA-1 experiment at the anti pp collider at CERN. In addition to measuring drift time for spatial information, the system provides a fast trigger (< 1 μs after drift time) and a second level trigger decision based on a fast microprocessor. The fast trigger part allows the use of the muon detector as an active trigger element, while a second level trigger decision using detailed digitizer data is included for adequate reduction of the trigger rate. The multipole time digitizer (MTD) is based on the use of fast RAMs (256 x 4) as 125 MHz shift registers, giving time bins of 8 ns and a time range of 2 μs (256 x 8 ns). The high input rate has imposed a fast readout and transfer to a buffer in the controller. The data in this buffer is reordered according to wire number and corresponding times. Together with look-up tables this allows fast processing of the data for a second level trigger. (orig.)

Ocean time-series near Bermuda: Hydrostation S and the US JGOFS Bermuda Atlantic time-series study

Science.gov (United States)

Michaels, Anthony F.; Knap, Anthony H.

1992-01-01

Bermuda is the site of two ocean time-series programs. At Hydrostation S, the ongoing biweekly profiles of temperature, salinity and oxygen now span 37 years. This is one of the longest open-ocean time-series data sets and provides a view of decadal scale variability in ocean processes. In 1988, the U.S. JGOFS Bermuda Atlantic Time-series Study began a wide range of measurements at a frequency of 14-18 cruises each year to understand temporal variability in ocean biogeochemistry. On each cruise, the data range from chemical analyses of discrete water samples to data from electronic packages of hydrographic and optics sensors. In addition, a range of biological and geochemical rate measurements are conducted that integrate over time-periods of minutes to days. This sampling strategy yields a reasonable resolution of the major seasonal patterns and of decadal scale variability. The Sargasso Sea also has a variety of episodic production events on scales of days to weeks and these are only poorly resolved. In addition, there is a substantial amount of mesoscale variability in this region and some of the perceived temporal patterns are caused by the intersection of the biweekly sampling with the natural spatial variability. In the Bermuda time-series programs, we have added a series of additional cruises to begin to assess these other sources of variation and their impacts on the interpretation of the main time-series record. However, the adequate resolution of higher frequency temporal patterns will probably require the introduction of new sampling strategies and some emerging technologies such as biogeochemical moorings and autonomous underwater vehicles.

Observational studies including time-varying treatments are prone to confounding. We compared time-varying Cox regression analysis, propensity score (PS) methods, and marginal structural models (MSMs) in a study of antidepressant [selective serotonin reuptake inhibitors (SSRIs)] use and the risk of hip fracture. A cohort of patients with a first prescription for antidepressants (SSRI or tricyclic antidepressants) was extracted from the Dutch Mondriaan and Spanish Base de datos para la Investigación Farmacoepidemiológica en Atención Primaria (BIFAP) general practice databases for the period 2001-2009. The net (total) effect of SSRI versus no SSRI on the risk of hip fracture was estimated using time-varying Cox regression, stratification and covariate adjustment using the PS, and MSM. In MSM, censoring was accounted for by inverse probability of censoring weights. The crude hazard ratio (HR) of SSRI use versus no SSRI use on hip fracture was 1.75 (95%CI: 1.12, 2.72) in Mondriaan and 2.09 (1.89, 2.32) in BIFAP. After confounding adjustment using time-varying Cox regression, stratification, and covariate adjustment using the PS, HRs increased in Mondriaan [2.59 (1.63, 4.12), 2.64 (1.63, 4.25), and 2.82 (1.63, 4.25), respectively] and decreased in BIFAP [1.56 (1.40, 1.73), 1.54 (1.39, 1.71), and 1.61 (1.45, 1.78), respectively]. MSMs with stabilized weights yielded HR 2.15 (1.30, 3.55) in Mondriaan and 1.63 (1.28, 2.07) in BIFAP when accounting for censoring and 2.13 (1.32, 3.45) in Mondriaan and 1.66 (1.30, 2.12) in BIFAP without accounting for censoring. In this empirical study, differences between the different methods to control for time-dependent confounding were small. The observed differences in treatment effect estimates between the databases are likely attributable to different confounding information in the datasets, illustrating that adequate information on (time-varying) confounding is crucial to prevent bias.

[Action tendencies of respect-related emotions: Focus on emotion episodes in Japanese university students].

Science.gov (United States)

Muto, Sera

2016-06-01

This study examined the action tendencies of respect-related emotions in Japanese university students. Participants (n = 405) randomly received a questionnaire about one of six respect-related emotions: (a) keiai (respect mingled with mild love); (b) shinsui (idolatry worship, and adoration); (c) ifu (awe mingled with fear); (d) kanshin (admiration); (e) kyotan (wonder); and (f) sonkei (respect proper) and were asked to recall a situation they felt the emotion. Next, they rated how much they felt like doing the respect-related (intrapersonal or interpersonal) actions in the situation. Statistical analysis revealed several action tendencies of respect-related emotions, however, the degree of each differed between the prototypical episodes of the emotions (a)-(e). The action tendency pattern of sonkei was most similar to that of keiai, therefore keiai could be considered as the prototypical feeling of sonkei in university students. Furthermore, almost all the respect-related emotions tended to strongly motivate willingness for self-correction and improvement. These findings suggest that respect-related emotions play an important role in self-improvement and building good relationships with superiors, at least in late adolescence.

Effects of computing time delay on real-time control systems

Shin, Kang G.; Cui, Xianzhong

1988-01-01

The reliability of a real-time digital control system depends not only on the reliability of the hardware and software used, but also on the speed in executing control algorithms. The latter is due to the negative effects of computing time delay on control system performance. For a given sampling interval, the effects of computing time delay are classified into the delay problem and the loss problem. Analysis of these two problems is presented as a means of evaluating real-time control systems. As an example, both the self-tuning predicted (STP) control and Proportional-Integral-Derivative (PID) control are applied to the problem of tracking robot trajectories, and their respective effects of computing time delay on control performance are comparatively evaluated. For this example, the STP (PID) controller is shown to outperform the PID (STP) controller in coping with the delay (loss) problem.

2000-01-01

We describe the development of a real time fuzzy controller aimed at an adequate core axial power distribution inside a pressurized water reactor (PWR). The system has been implemented in simulation using the EDF model on Matlab-Simulink on a Sun workstation. Some experiments tests at different power levels have been performed: several low levels modeling falls in the network consumption and test modeling falls in the consumption followed by a recovery of the consumption. The results of all these experiments will be discussed. (orig.)

A time-to-amplitude converter with constant fraction timing discriminators for short time interval measurements

International Nuclear Information System (INIS)

Kostamovaara, J.; Myllylae, R.

1985-01-01

The construction and the performance of a time-to-amplitude converter equipped with constant fraction discriminators is described. The TAC consists of digital and analog parts which are constructed on two printed circuit boards, both of which are located in a single width NIM module. The dead time of the TAC for a start pulse which is not followed by a stop pulse within the time range of the device (proportional100 ns) is only proportional100 ns, which enables one to avoid counting rate saturation even with a high random input signal rate. The differential and integral nonlinearities of the TAC are better than +-1.5% and 0.05%, respectively. The resolution for input timing pulses of constant shape is 20 ps (fwhm), and less than 10 ps (fwhm) with a modification in the digital part. The walk error of the constant fraction timing discriminators is presented and various parameters affecting it are discussed. The effect of the various disturbances in linearity caused by the fast ECL logic and their minimization are also discussed. The time-to-amplitude converter has been used in positron lifetime studies and for laser range finding. (orig.)

'Management is a black art'--professional ideologies with respect to temporomandibular disorders.

Science.gov (United States)

Durham, J; Exley, C; Wassell, R; Steele, J G

2007-06-09

To gain a deeper understanding of the range of influences on the full range of dental professionals who provide treatment for temporomandibular disorders (TMD). Qualitative semi-structured interviews. Primary and secondary care in the North and South of the United Kingdom. A criterion-based purposive sample was taken of dental practitioners, comprising primary and secondary care practitioners. In-depth interviews were conducted and data collection and analysis occurred concurrently until data saturation was achieved. DATA AND DISCUSSION: There was a reported lack of adequate remuneration for provision of treatment for TMD within primary care. This alongside the primary care practitioners' reported uncertainty in diagnosis of TMD appeared to lead to a propensity for referral to secondary care. Practitioners recognised a poor and scanty evidence base on which to base their care, and this allowed for idiosyncratic practice. Often the outcome measure for treatment was a subjective questioning of the patient focussing mainly on relief of pain. There is a need for better quality evidence on which to base TMD treatment, more continuing professional development and improvement in contracting arrangements to enable primary practitioners to feel confident in managing TMD.

Four-level time decomposition quasi-static power flow and successive disturbances analysis. [Power system disturbances

Energy Technology Data Exchange (ETDEWEB)

Jovanovic, S M [Nikola Tesla Inst., Belgrade (YU)

1990-01-01

This paper presents a model and an appropriate numerical procedure for a four-level time decomposition quasi-static power flow and successive disturbances analysis of power systems. The analysis consists of the sequential computation of the zero, primary, secondary and tertiary quasi-static states and of the estimation of successive structural disturbances during the 1200 s dynamics after a structural disturbance. The model is developed by detailed inspection of the time decomposition characteristics of automatic protection and control devices. Adequate speed of the numerical procedure is attained by a specific application of the inversion matrix lemma and the decoupled model constant coefficient matrices. The four-level time decomposition quasi-static method is intended for security and emergency analysis. (author).

Liver conversion of docosahexaenoic and arachidonic acids from their 18-carbon precursors in rats on a DHA-free but α-LNA-containing n-3 PUFA adequate diet.

The long-chain polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA, 20:5n-3), docosahexaenoic acid (DHA, 22:6n-3), and arachidonic acid (AA, 20:4n-6), are critical for health. These PUFAs can be synthesized in liver from their plant-derived precursors, α-linolenic acid (α-LNA, 18:3n-3) and linoleic acid (LA, 18:2n-6). Vegetarians and vegans may have suboptimal long-chain n-3 PUFA status, and the extent of the conversion of α-LNA to EPA and DHA by the liver is debatable. We quantified liver conversion of DHA and other n-3 PUFAs from α-LNA in rats fed a DHA-free but α-LNA (n-3 PUFA) adequate diet, and compared results to conversion of LA to AA. [U-(13)C]LA or [U-(13)C]α-LNA was infused intravenously for 2h at a constant rate into unanesthetized rats fed a DHA-free α-LNA adequate diet, and published equations were used to calculate kinetic parameters. The conversion coefficient k(⁎) of DHA from α-LNA was much higher than for AA from LA (97.2×10(-3) vs. 10.6×10(-3)min(-1)), suggesting that liver elongation-desaturation is more selective for n-3 PUFA biosynthesis on a per molecule basis. The net daily secretion rate of DHA, 20.3μmol/day, exceeded the reported brain DHA consumption rate by 50-fold, suggesting that the liver can maintain brain DHA metabolism with an adequate dietary supply solely of α-LNA. This infusion method could be used in vegetarians or vegans to determine minimal daily requirements of EPA and DHA in humans. Published by Elsevier B.V.
