    Salmonella spp. are important food-borne pathogens. Abattoir studies demonstrated that almost a quarter of British finisher pigs might carry Salmonella, which led to the introduction by the British Pig Executive of their Zoonoses Action Plan (ZAP) to monitor the Salmonella status of United Kingdom pig farms by testing meat juice samples using an ELISA system. We used the K-function and approaches from the field of geostatistics to study routine data from ZAP. We demonstrated that there is statistical evidence that geographically localized anomalies of Salmonella infection were present in one of three regions studied. The physical mechanisms underlying this structure remain unclear: spatial structure might be present as a result of shared spatially structured (second-order) or non-spatially structured (first-order) risk factors, transmission processes, or a combination of both. We have demonstrated a way to use routinely collected surveillance data to enhance the knowledge of spatial disease epidemiology.

    Peripartum cardiomyopathy (PPCM) is an uncommon form of congestive heart failure, affecting obstetric patients around the time of delivery. The epidemiology of PPCM is infrequently reported. This study was undertaken to define the prevalence, presentation and outcome of PPCM among women giving birth in a teaching hospital in Malaysia. A retrospective case record analysis was conducted on all patients admitted and diagnosed with PPCM at the University Malaya Medical Centre, Kuala Lumpur, Malaysia, from 1 January 2000 to 31 December 2009. All deliveries were undertaken in the same hospital. A total of 12 patients were diagnosed with PPCM during the ten-year study period. The prevalence of PPCM was 2.48 in 100,000 (1 in 40,322) live births. Nine women were diagnosed with PPCM within five months of delivery. Three women had twin pregnancies. There was one death in the group (mortality rate 8.3%). The mean left ventricular ejection fraction at the time of diagnosis was 28.9% ± 8.5% (range 15%-40%). Following the index event, left ventricular function normalised in six of the nine patients (66.7%) who underwent subsequent echocardiography one year later. All patients were treated with standard heart failure therapy. Two patients with normalised left ventricular function had subsequent pregnancies - one pregnancy was terminated at seven weeks and the other patient delivered uneventfully at full term. PPCM is uncommon. The outcome in our series was favourable, with 66.7% of patients with PPCM recovering their left ventricular function. The mortality rate was 8.3%.

    2012-07-01

    The idea of analysing the general favourability for the occurrence of an event was presented in 2006 through a mathematical function. However, even when favourability has been used in species distribution modelling, the conceptual framework of this function is not yet well perceived among many researchers. The present paper is conceived for providing a wider and more in-depth presentation of the idea of favourability; concretely, we aimed to clarify both the concept and the main distinctive characteristics of the favourability function, especially in relation to probability and suitability, the most common outputs in species distribution modelling. As the capabilities of the favourability function go beyond species distribution modelling, we also illustrate its usefulness for different research disciplines for which this function remains unknown. In particular, we stressed that the favourability function has potential to be applied in all the cases where the probability of occurrence of an event is analysed, such as, for example, habitat selection or epidemiological studies.

    Full Text Available Climate is the main environmental driver determining the spatial distribution of most tree species at the continental scale. We investigated the distribution change of European beech and Norway spruce due to climate change. We applied a species distribution model (SDM, driven by an ensemble of 21 regional climate models in order to study the shift of the favourability distribution of these species. SDMs were parameterized for 1971–2000, as well as 2021–2050 and 2071–2100 using the SRES scenario A1B and three physiological meaningful climate variables. Growing degree sum and precipitation sum were calculated for the growing season on a basis of daily data. Results show a general north-eastern and altitudinal shift in climatological favourability for both species, although the shift is more marked for spruce. The gain of new favourable sites in the north or in the Alps is stronger for beech compared to spruce. Uncertainty is expressed as the variance of the averaged maps and with a density function. Uncertainty in species distribution increases over time. This study demonstrates the importance of data ensembles and shows how to deal with different outcomes in order to improve impact studies by showing uncertainty of the resulting maps.

    This study aimed to assess public attitudes in Japan to the promotion of genomic selection in crop studies and to examine associated factors. We analysed data from a nationwide opinion survey. A total of 4,000 people were selected from the Japanese general population by a stratified two-phase sampling method, and 2,171 people participated by post; this survey asked about the pros and cons of crop-related genomic studies promotion, examined people's scientific literacy in genomics, and investigated factors thought to be related to genomic literacy and attitude. The relationships were examined using logistic regression models stratified by gender. Survey results showed that 50.0% of respondents approved of the promotion of crop-related genomic studies, while 6.7% disapproved. No correlation was found between literacy and attitude towards promotion. Trust in experts, belief in science, an interest in genomic studies and willingness to purchase new products correlated with a positive attitude towards crop-related genomic studies.

    The main goal of this randomized controlled single-blinded pilot study was to study whether, independent of weight loss, a Palaeolithic-type diet alters characteristics of the metabolic syndrome. Next we searched for outcome variables that might become favourably influenced by a Paleolithic-type diet and may provide new insights in the pathophysiological mechanisms underlying the metabolic syndrome. In addition, more information on feasibility and designing an innovative dietary research program on the basis of a Palaeolithic-type diet was obtained. Thirty-four subjects, with at least two characteristics of the metabolic syndrome, were randomized to a two weeks Palaeolithic-type diet (n = 18) or an isoenergetic healthy reference diet, based on the guidelines of the Dutch Health Council (n = 14). Thirty-two subjects completed the study. Measures were taken to keep bodyweight stable. As primary outcomes oral glucose tolerance and characteristics of the metabolic syndrome (abdominal circumference, blood pressure, glucose, lipids) were measured. Secondary outcomes were intestinal permeability, inflammation and salivary cortisol. Data were collected at baseline and after the intervention. Subjects were 53.5 (SD9.7) year old men (n = 9) and women (n = 25) with mean BMI of 31.8 (SD5.7) kg/m2. The Palaeolithic-type diet resulted in lower systolic blood pressure (-9.1 mmHg; P = 0.015), diastolic blood pressure (-5.2 mmHg; P = 0.038), total cholesterol (-0.52 mmol/l; P = 0.037), triglycerides (-0.89 mmol/l; P = 0.001) and higher HDL-cholesterol (+0.15 mmol/l; P = 0.013), compared to reference. The number of characteristics of the metabolic syndrome decreased with 1.07 (P = 0.010) upon the Palaeolithic-type diet, compared to reference. Despite efforts to keep bodyweight stable, it decreased in the Palaeolithic group compared to reference (-1.32 kg; P = 0.012). However, favourable effects remained after post-hoc adjustments for this

    This report is a synthesis of the possibilities of CO{sub 2} storage in the Spanish subsurface. Compilation and analysis of geological information has been carried out, looking at surface and subsurface, in order to make a pre-selection of potential favourable units for CO{sub 2} storage, taking in account that each of this storages needs a confining formation to seal the storage. Before the storage selection, a general description of the great geological units of the Iberian Peninsula is done. Afterwards, borehole logging from petroleum exploration is analysed in these units, formations and areas of interest. The aim is to finally obtain a description of selected units and their possibilities of CO{sub 2} storage. (Author) 17 refs.

    Background A major cornerstone of evolutionary biology theory is the explanation of the emergence of cooperation in communities of selfish individuals. There is an unexplained tendency in the plant and animal world – with examples from alpine plants, worms, fish, mole-rats, monkeys and humans – for cooperation to flourish where the environment is more adverse (harsher) or more unpredictable. Results Using mathematical arguments and computer simulations we show that in more adverse environments individuals perceive their resources to be more unpredictable, and that this unpredictability favours cooperation. First we show analytically that in a more adverse environment the individual experiences greater perceived uncertainty. Second we show through a simulation study that more perceived uncertainty implies higher level of cooperation in communities of selfish individuals. Conclusion This study captures the essential features of the natural examples: the positive impact of resource adversity or uncertainty on cooperation. These newly discovered connections between environmental adversity, uncertainty and cooperation help to explain the emergence and evolution of cooperation in animal and human societies.

    Full Text Available There is no consensus and a limited evidence base for choice of contrast agents (CA in angiography. This study evaluated the impact of iohexol and iodixanol CA on fibrinolytic factors (tissue plasminogen activator [t-PA] and plasminogen activator inhibitor-1 [PAI-1], as well as platelet-monocyte conjugates in cardiac patients undergoing elective angiography in a double-blind, randomised parallel group study.Patients (men, 50-70 years old; n = 12 were randomised to receive either iohexol (Omnipaque; n = 6 or iodixanol (Visipaque; n = 6 during elective angiography at Raigmore Hospital, Inverness, UK. Arterial and venous blood samples were drawn prior to CA delivery and following angiography. Assessment of platelet-monocyte conjugation, t-PA and PAI-1 antigen and activity was conducted in samples pre- and post-angiography.Plasma t-PA antigen was depressed equally in the study groups after angiography, but there was a greater reduction in PAI-1 antigen in the group receiving iodixanol. These findings corresponded to a substantial reduction in t-PA activity in patients receiving iohexol, with no change in those receiving iodixanol (P = 0.023 between the CA groups. Both CAs caused a reduction in platelet-monocyte conjugation, with no difference between the groups. No adverse events were reported during the trial.Avoiding reduced plasma t-PA activity might be an important consideration in choosing iodixanol over iohexol in patients at risk of thrombosis following angiography.

  1. Employee participation in the private sector in Malaysia: The Applicability of Favourable Conjunctures Model

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available EP is one crucial aspect of the employment relationship in both private and public organisations in many countries. In 2001, Poole, Lansbury and Wiles developed a model for comparative EP, which they named the Favourable Conjunctures Model. So far, this model has only been applied in developed countries such as the United States of America, United Kingdom, Australia and Europe. There it was applied in order to examine worker participation from the national perspective. No extensive study has been conducted using this model to explain worker participation practices at the company level. In parallel with this aspect, this model also has never been used to explain the nature of EP in the Asian developing countries. This current research will use the Favourable Conjunctures Model to examine the nature of EP in private enterprises based on empirical study carried out in Malaysia. The argument of this paper is that the Favourable Conjunctures Model of Industrial Democracy (Poole et al. 2001 is inadequate to elucidate the characteristics of EP in Malaysia. Based on empirical findings from three private companies in Malaysia, the paper argues that there are many contextual factors that influence the nature of EP in Malaysian private companies that are not taken into account by the model. They are:multi-ethnic (cultural influences, the repressive role of state in the Malaysian industrial relations, the New Economic Policy and industrialisation plan, Islamic working ethics, the influence of a British colonial history, lack of training among non-managerial employees in EP, the impact of foreign direct investment on industrial relations, to identify a few. Based on this study, it is proposed that the present Favourable Conjunctures Model of Industrial Democracy (Poole et al. 2001 be modified based on the contextual factors discussed above. The paper concludes that the western model of EP could not be directly applied in Malaysia without some adjustment of

  4. Arguments in favour of compulsory treatment of opioid dependence.

    Science.gov (United States)

    Wu, Zunyou

    2013-02-01

    Twelve agencies of the United Nations, including the World Health Organization, have issued a joint statement that calls on Member States to replace the compulsory detention of people who use opioids in treatment centres with voluntary, evidence-informed and rights-based health and social services. The arguments in favour of this position fall into three broad categories: Compulsory treatment centres infringe on an individual's liberty, they put human beings at risk of harm, and evidence of their effectiveness against opioid dependence has not been generated. The United Nations statement underscores that although countries apply different criteria for sending individuals to compulsory treatment centres, detention often takes place without due process, legal safeguards or judicial review. This clearly violates internationally recognized human rights standards. Furthermore, people who are committed to these centres are often exposed to physical and sexual violence, forced labour and sub-standard living conditions. They are often denied health care, despite their heightened vulnerability to HIV infection and tuberculosis. Finally, there is no evidence, according to the statement, that these centres offer an environment that is conducive to recovery from opioid dependence or to the rehabilitation of commercial sex workers or of children who have suffered sexual exploitation, abuse or lack of care and protection. The author of this paper sets forth several arguments that counter the position taken by the United Nations and argues in favour of compulsory treatment within a broader harm reduction strategy aimed at protecting society as well as the individual concerned.

    2010-01-01

    The common attribute of all Big Bang cosmologies is that they are based on the assumption that the universe is expanding. However examination of the evidence for this expansion clearly favours a static universe. The major topics considered are: Tolman surface brightness, angular size, type 1a supernovae, gamma ray bursts, galaxy distributions, quasar distributions, X-ray background radiation, cosmic microwave background radiation, radio source counts, quasar variability and the Butcher--Oemler effect. An analysis of the best raw data for these topics shows that they are consistent with expansion only if there is evolution that cancels the effects of expansion. An alternate cosmology, curvature cosmology, is in full agreement with the raw data. This tired-light cosmology predicts a well defined static and stable universe and is fully described. It not only predicts accurate values for the Hubble constant and the temperature of cosmic microwave background radiation but shows excellent agreement with most of the...

    Isocitrate dehydrogenase (IDH) gene from Staphylococcus aureus ATCC12600 was cloned, sequenced and characterized (HM067707). PknB site was observed in the active site of IDH; thus, it was predicted as IDH may be regulated by phosphorylation. Therefore, in this study, PknB, alkaline phosphatase III (SAOV 2675) and IDH genes (JN695616, JN645811 and HM067707) of S. aureus ATCC12600 were over expressed from clones PV 1, UVPALP-3 and UVIDH 1. On passing the cytosloic fractions through nickel metal chelate column, pure enzymes were obtained. Phosphorylation of pure IDH by PknB resulted in the complete loss of activity and was restored upon dephosphorylation with SAOV 2675 which indicated that phosphorylation and dephosphorylation regulate IDH activity in S. aureus. Further, when S. aureus ATCC12600 was grown in BHI broth, decreased IDH activity and increased biofilm units were observed; therefore, this regulation of IDH alters redox status in this pathogen favouring biofilm formation.

    Because of its geographical location, topography, and climate, South Florida has unique water problems. When the rainfall situation is combined with changing land use patterns and increasing population growth rates, the result is often water shortages in some areas and floods in others. This study unit looks at some of the reasons for the present…

    Associations between biological traits of animals and climate are well documented by physiological and local-scale studies. However, whether an ecophysiological phenomenon can affect large-scale biogeographical patterns of insects is largely unknown. Insects absorb energy from the sun to become mobile, and their colouration varies depending on the prevailing climate where they live. Here we show, using data of 473 European butterfly and dragonfly species, that dark-coloured insect species are favoured in cooler climates and light-coloured species in warmer climates. By comparing distribution maps of dragonflies from 1988 and 2006, we provide support for a mechanistic link between climate, functional traits and species that affects geographical distributions even at continental scales. Our results constitute a foundation for better forecasting the effect of climate change on many insect groups.

    Understanding decisions is the fundamental aim of the behavioural sciences. The theory of rational choice is based on axiomatic principles such as transitivity and independence of irrelevant alternatives (IIA). Empirical studies have demonstrated that the behaviour of humans and other animals often seems irrational; there can be a lack of transitivity in choice and seemingly irrelevant alternatives can alter decisions. These violations of transitivity and IIA undermine rational choice theory....

    Understanding decisions is the fundamental aim of the behavioural sciences. The theory of rational choice is based on axiomatic principles such as transitivity and independence of irrelevant alternatives (IIA). Empirical studies have demonstrated that the behaviour of humans and other animals often seems irrational; there can be a lack of transitivity in choice and seemingly irrelevant alternatives can alter decisions. These violations of transitivity and IIA undermine rational choice theory. However, we show that an individual that is maximizing its rate of food gain can exhibit failure of transitivity and IIA. We show that such violations can be caused because a current option may disappear in the near future or a better option may reappear soon. Current food options can be indicative of food availability in the near future, and this key feature can result in apparently irrational behaviour.

    Lack of information is a constraint but ignorance can sometimes assist the evolution of cooperation by constraining selfishness. We discuss examples involving both ignorance of role or pay-off and ignorance of relatedness. Ignorance can favour cooperative traits like grouping and warning coloration and reduce conflicts from meiotic drive, imprinting, greenbeards and various forms of nepotism.

    In 2004, Patient Rights Units were established in all public hospitals in Turkey to allow patients to voice their complaints about services. To determine what violations are reflected into the complaint mechanism, the pattern over time, and patients' expectations of the services. Descriptive study. A retrospective study performed using the complaint database of the Istanbul Health Directorate, from 2005 to 2011. The results indicate that people who are older than 40 years, women, and those with less than high school education are the most common patients in these units. A total of 218,186 complaints were filed. Each year, the number of complaints increased compared to the previous year, and nearly half of the applications were made in 2010 and 2011 (48.9%). The three most frequent complaints were "not benefiting from services in general" (35.4%), "not being treated in a respectable manner and in comfortable conditions" (17.8%), and "not being properly informed" (13.5%). Two-thirds of the overall applications were found in favour of the patients (63.3%), and but this rate has decreased over the years. Patients would like to be treated in a manner that respects their human dignity. Educating healthcare workers on communication skills might be a useful initiative. More importantly, health policies and the organisation of services should prioritise patient rights. It is only then would be possible to exercise patient rights in reality.

  3. Cryptic female choice via sperm dumping favours male copulatory courtship in a spider.

    Science.gov (United States)

    Peretti, A V; Eberhard, W G

    2010-02-01

    Males of many animals perform 'copulatory courtship' during copulation, but the possible reproductive significance of this behaviour has seldom been investigated. In some animals, including the spider Physocyclus globosus (Pholcidae), the female discards sperm during or immediately following some copulations. In this study, we determined which of several variables associated with copulation correlated with paternity success in P. globosus when two males mate with a single female. Then, by determining which of these variables also correlated with sperm dumping, we inferred which variables may affect paternity via the mechanism of sperm dumping. Male abdomen vibration (a copulatory courtship behaviour) and male genitalic squeezing both correlated with both paternity and sperm dumping; so, these traits may be favoured by biased sperm dumping. Biased sperm dumping may also be the mechanism by which possible cryptic female choice favours another male trait that was the subject of a previous study, responsiveness to female stridulation.

    The question whether euthanasia should be legalised has led to substantial public debate in France. The objective of this study in a sample of French physicians was to establish the potential determinants of a favourable opinion about euthanasia in general and when faced with a specific situation as embodied in the Humbert affair. The study was a cross-sectional survey investigating two different samples of medical doctors: (1) those specialised in palliative care and affiliated to the French Society for Patient Accompaniment and Palliative Care; (2) medical interns (medical doctors in training course) in a French medical university (Marseille). A questionnaire was sent (email) to each voluntary participant including sociodemographics, professional status, mention of believing in God, and opinion about euthanasia (the question was designed to assess the general opinion about euthanasia and the opinion about a specific case, the Vincent Humbert' case (a man who was rendered quadriplegic, blind, and mute after an accident and has requested euthanasia). A total of 413 physicians participated in the research (participation rate: 48.5%). Less than half of the population were favourable to euthanasia in general and almost two-thirds of the population were favourable to Vincent Humbert's request for euthanasia. Based on the multivariate analysis, individuals believing in God and being a medical intern were significant independent factors linked to having a favourable opinion about euthanasia in general and about the Vincent Humbert's request. There is still no study in France on the development of opinion about euthanasia and its impact. The issue goes beyond the strictly professional sphere and involves broader socio-political stakes. These stakes do not necessarily take into account medical practices and experiences or the desires of end-of-life patients. The professional upheaval that the future French legal framework will doubtlessly trigger will require further

    Hydrogen is one of the alternative transport fuels expected to replace conventional oil based fuels. The paper finds that it is possible for non-fossil-based hydrogen to become the lowest cost fuel without favourable tax treatment. The order of per kilometre cost depends on performance in hydrogen...... production, the international oil price, and fuel taxes. At low oil prices, the highest per kilometre costs were found for non-fossil power-based hydrogen, the second highest for natural gas-based hydrogen, and the lowest for conventional fuels. At high oil prices, this ranking is reversed and non......-fossil power-based hydrogen becomes the most cost competitive fuel. General fuel taxes lower the threshold at which the international oil price reverses this competitiveness order. The highest fuel tax rates applied in Europe lowers this threshold oil price considerably, whereas the lowest fuel taxes may...

  6. Physiological adaptations to weight loss and factors favouring weight regain.

    Science.gov (United States)

    Greenway, F L

    2015-08-01

    Obesity is a major global health problem and predisposes individuals to several comorbidities that can affect life expectancy. Interventions based on lifestyle modification (for example, improved diet and exercise) are integral components in the management of obesity. However, although weight loss can be achieved through dietary restriction and/or increased physical activity, over the long term many individuals regain weight. The aim of this article is to review the research into the processes and mechanisms that underpin weight regain after weight loss and comment on future strategies to address them. Maintenance of body weight is regulated by the interaction of a number of processes, encompassing homoeostatic, environmental and behavioural factors. In homoeostatic regulation, the hypothalamus has a central role in integrating signals regarding food intake, energy balance and body weight, while an 'obesogenic' environment and behavioural patterns exert effects on the amount and type of food intake and physical activity. The roles of other environmental factors are also now being considered, including sleep debt and iatrogenic effects of medications, many of which warrant further investigation. Unfortunately, physiological adaptations to weight loss favour weight regain. These changes include perturbations in the levels of circulating appetite-related hormones and energy homoeostasis, in addition to alterations in nutrient metabolism and subjective appetite. To maintain weight loss, individuals must adhere to behaviours that counteract physiological adaptations and other factors favouring weight regain. It is difficult to overcome physiology with behaviour. Weight loss medications and surgery change the physiology of body weight regulation and are the best chance for long-term success. An increased understanding of the physiology of weight loss and regain will underpin the development of future strategies to support overweight and obese individuals in their efforts

  9. Partner switching can favour cooperation in a biological market.

    Schwagmeyer, P L

    2014-09-01

    Intraspecific cooperation and interspecific mutualisms can be promoted by mechanisms that reduce the frequency with which cooperative organisms are exploited by unhelpful partners. One such mechanism consists of changing partners after interacting with an uncooperative individual. I used McNamara et al.'s (Nature, 451, 2008, 189) partner switching model as a framework to examine whether this mechanism can select for increased cooperative investment by house sparrows (Passer domesticus) collaborating to rear offspring; previous research on this species has shown that substantial cooperative investments by both pair members are required to achieve high pay-offs from collaborating. I found that the poorer the outcome of a breeding attempt relative to the number of eggs the female invested, the greater the likelihood of partner switching. The incidence of partner switching changed seasonally, with peak switching coinciding with an increase in the number of alternative partners available to females. After females switched partners, their breeding outcomes rose to match those of females that remained with the same partner; this was not the case for males that switched partners. Consistent with the model's prediction, males in stable partnerships achieved over 25% higher than average reproductive success, which was attributable to both persistently good breeding outcomes and their older partners' high fecundity. These results provide empirical support for the hypothesis that partner switching favours increased cooperative investment levels, and they demonstrate that variation in the relative value of by-product benefits can enhance that process.

  10. Evolution of trust and trustworthiness: social awareness favours personality differences.

    McNamara, John M; Stephens, Philip A; Dall, Sasha R X; Houston, Alasdair I

    2009-02-22

    Interest in the evolution and maintenance of personality is burgeoning. Individuals of diverse animal species differ in their aggressiveness, fearfulness, sociability and activity. Strong trade-offs, mutation-selection balance, spatio-temporal fluctuations in selection, frequency dependence and good-genes mate choice are invoked to explain heritable personality variation, yet for continuous behavioural traits, it remains unclear which selective force is likely to maintain distinct polymorphisms. Using a model of trust and cooperation, we show how allowing individuals to monitor each other's cooperative tendencies, at a cost, can select for heritable polymorphisms in trustworthiness. This variation, in turn, favours costly 'social awareness' in some individuals. Feedback of this sort can explain the individual differences in trust and trustworthiness so often documented by economists in experimental public goods games across a range of cultures. Our work adds to growing evidence that evolutionary game theorists can no longer afford to ignore the importance of real world inter-individual variation in their models.

    Full Text Available Objective: In this study it was aimed to establish the favourable health behaviours in the life style of women, who also are in charge, and carry the responsibility of the whole family’s health. Material and Method: A questionnaire, inquiring about some favourable health behaviours, was applied to 421 women aged 18-64, living in an urban region in Kayseri. Results: The mean age of the study group was 36.2±11.1, 57.1% were housewives, 74.3% were married, and the educational level of 62.7% was high school and above. The rate of obtaining information from health personnel was 9.7%, and most women(31.1% stated media as their source of information. 67.0% did not smoke. 44.4% of the study group were with in normal weight, and 66.3% stated that they had breakfast. 32.3% of the women stated that they restricted salt in food, and 18.8% restricted sugar, 20.4% tried not to consume tea following a meal and 32.1% stated that they were always careful about not using saturated fat while cooking. 16.2% of the women stated that they self-examined their breats on a regular basis, 54.0% that they did so sometimes, 41.6% had had a clinical breast examination. The rate of mammograhpic evaluation above the age of 40 was 78.0%. Conclusion: The awareness about and the applications for favourable health behaviours as a life style were found to be insufficient in women. It is the duty and responsibility of health personnel to establish healthy life style behaviours in women. [TAF Prev Med Bull 2012; 11(5.000: 521-528

  20. Experimental evidence for mutual inter- and intrasexual selection favouring a crested auklet ornament.

    Science.gov (United States)

    Jones; Hunter

    1999-03-01

    During the breeding season, female and male crested auklets Aethia cristatella (Alcidae), display similar conspicuous crest ornaments composed of elongated forward-curving feathers on their foreheads. Based on quantifications of brief agonistic interactions at a large breeding colony, we found that crest length was strongly correlated with dominance within both sexes. Across the full range of crest length, individuals with longer crests were dominant over shorter-crested individuals in agonistic interactions involving same-sex adults. Within subadults (2-year-olds of unknown sex), there was a similar trend towards longer-crested individuals being dominant. In agonistic interactions involving individuals of different sex and age, adult males were dominant over adult females and adults were dominant over subadults, regardless of crest length. In an experiment in which we manipulated crest length using life-size realistic models, male auklets that responded were less aggressive to male models with longer crests than to models with normal or shorter crests, confirming that crest length by itself signals dominance status. In a related experiment in which we controlled intrasexual competition, both males and females responded to opposite-sex models with more frequent sexual displays when the models had long crests compared with those having short crests, suggesting that crested auklets also have mating preferences that favour long crest ornaments. Taken together, these results support the idea that the crest ornament is favoured by both intra- and intersexual selection. Copyright 1999 The Association for the Study of Animal Behaviour.

    1993-06-01

    This feasibility study examines a range of alternatives and provides recommendations for selecting a preferred alternative for remediating contamination at the 200-BP-1 operable unit. The 200-BP-1 operable unit is located in the center of the Hanford Site along the northern boundary of the 200 East Area. The 241-BY Tank Farm is located immediately to the south of the operable unit. 200-BP-1 is a source operable unit with contaminated soils associated primarily with nine inactive cribs (known as the 216-B cribs). These cribs were used for disposal of low-level radioactive liquid waste from U Plant uranium recovery operations, and waste storage tank condensate from the adjacent 241-BY Tank Farm. The cribs used for disposal of U Plant waste were in operation from 1955--1965, and the cribs used for disposal of tank condensate were in operation from 1965--1975. In addition to the cribs, four unplanned releases of radioactive materials have occurred within the operable unit. Contaminated surface soils associated with the unplanned releases have been consolidated over the cribs and covered with clean soil to reduce contaminant migration and exposure. Discharge of wastes to the cribs has resulted in soil and groundwater contamination. The groundwater is being addressed as part of the 200 East Aggregate Area, groundwater operable unit. Contaminated soils at the site can be categorized by the types of contaminants, their distribution in the soil column, and the risk posed by the various potential exposure pathways. Below the clean soil cover, the near surface soils contain low-levels of contamination with cesium-137, radium-226, strontium-90, thorium-228, and uranium. The lifetime incremental cancer risk associated with these soils if they were exposed at the surface is 9{times}10{sup {minus}5}.

    1986-01-01

    A simple rabbit care unit for peripheral intravenous feeding and metabolic studies was developed. The unit consists of six aluminum boxes with a common cover. Inverted T-shaped mobile supports hanging from the upper horizontal part of a frame hold the infusion lines. The side walls of the box prevent the rabbit from turning around, but other movements are possible. After initial training with 21 surgically treated animals, there was only one early anesthetic death among the subsequent 21 rabbits (4.8%). There was one late death (4.8%), and one animal was slightly, and two animals clearly, deteriorated. The ear vein cannula had to be changed in one-third of the animals not more than 3 days from the outset. Problems associated with the infusion systems or urinary bladder catheterization were minor. The results showed that it is practical to infuse rabbits via a peripheral intravenous route in a semi-restraining metabolic unit. The cases of late death and deterioration can be explained in part by the stress of experimental conditions with starvation and surgery, rather than by the effect of the metabolic unit alone. With previous experience in treating rabbits, we find the period required to learn this technique is short.

  4. A sociological study of bed blocking in psychiatric rehabilitation units.

    Leighton, Kevin

    2002-08-01

    This study focuses on the reported problem of psychiatric patients who are 'bed-blocking' mental health rehabilitation units. It explores the concept of individualized care within psychiatric nursing and argues that this 'received view' is counterproductive for some client groups. Individualized care assumes a number of mainstream social values and beliefs that may conflict radically with the attitudes to life (ideologies) of some service users. These clients may resist normalisation, independence and individualism, preferring instead a more collective, pastoral and spiritual lifestyle. Clients and nurses may reject culture-biased care policy, using various strategies to neutralize individualized care in practice. In the absence of a coherent alternative, such action may lead to frustration, alienation and bed blocking. The study uses structured and unstructured interviews in two psychiatric units to examine this hypothesis.

    When pension systems are contrasted it is common to use simplified demographic models, such as overlapping generation models with time-invariant mortality. Breaking with this tradition, we show that for a population with increasing longevity, the pay-as-you-go (PAYG) system may be more advantageous than a funded system (FS). Increasing longevity favours the PAYG system because for the workers living longer at retirement than current retirees, it is less costly to fund others' current pensions than their own. At present, the effect amounts to around 15 per cent in terms of the dependency ratio, or six more years at work in the FS, or 1 per cent per annum in terms of the real interest rate. In most developed countries the effect substantially exceeds that of the usually studied biological interest rate.

    The aim of the study was to assess whether adults admitted to hospitals with both Intensive Care Units (ICU) and Intermediate Care Units (IMCU) have lower in-hospital mortality than those admitted to ICUs without an IMCU. An observational multinational cohort study performed on patients admitted to participating ICUs during a four-week period. IMCU was defined as any physically and administratively independent unit open 24 hours a day, seven days a week providing a level of care lower than an ICU but higher than a ward. Characteristics of hospitals, ICUs and patients admitted to study ICUs were recorded. The main outcome was all-cause in-hospital mortality until hospital discharge (censored at 90 days). One hundred and sixty-seven ICUs from 17 European countries enrolled 5,834 patients. Overall, 1,113 (19.1%) patients died in the ICU and 1,397 died in hospital, with a total of 1,397 (23.9%) deaths. The illness severity was higher for patients in ICUs with an IMCU (median Simplified Acute Physiology Score (SAPS) II: 37) than for patients in ICUs without an IMCU (median SAPS II: 29, P hospital characteristics, the odds ratio of mortality was 0.63 (95% CI 0.45 to 0.88, P = 0.007) in favour of the presence of IMCU. The protective effect of the IMCU was absent in patients who were admitted for basic observation, for example, after surgery (odds ratio 1.15, 95% CI 0.65 to 2.03, P = 0.630) but was strong in patients admitted to an ICU for other reasons (odds ratio 0.54, 95% CI 0.37 to 0.80, P = 0.002). The presence of an IMCU in the hospital is associated with significantly reduced adjusted hospital mortality for adults admitted to the ICU. This effect is relevant for the patients requiring full intensive treatment. Clinicaltrials.gov NCT01422070. Registered 19 August 2011.

    2016-11-01

    Displayed enthusiasm has been shown to relate to intrinsic motivation, vitality, and positive affect, but its effects on recall performance and time estimation have not yet been explored. This research aimed at studying the effects of a delivery style characterised by High Enthusiasm (HE) on recall, time estimation, and intrinsic motivation. In line with previous studies, effects on intrinsic motivation were expected. In addition, higher recall and lower time estimations were hypothesised. In two experiments, participants assigned to a HE condition or to a normal reading control condition listened to a narrative and to a descriptive passage. Then, they were asked to rate perceived time, enthusiasm, pleasure, interest, enjoyment and curiosity, before writing a free recall. Experiment 1 showed that in the HE condition, participants recalled more, were more intrinsically motivated, and expressed lower time estimations compared to the control condition. Experiment 2 confirmed the positive effects of HE reading compared to normal reading, using different passages and a larger sample.

    A grain boundary (GB) in graphene is a linear defect between two specifically oriented graphene edges, whose title angles are denoted as θ1 and θ2, respectively. Here we present a systematic theoretical study on the structure and stability of GBs in graphene as a function of the misorientation angle, Φ = (θ1-θ2) and the GB orientation in multi-crystalline graphene, which is denoted by Θ = (θ1 + θ2). It is surprising that although the number of disorders of the GB, i.e., the pentagon-heptagon pairs (5|7s), reaches the maximum at Φ∼ 30°, the GB formation energy versus the Φ curve reaches a local minimum. The subsequent M-shape of the Efvs. the Φ curve is due to the strong cancellation of the local strains around 5|7 pairs by the "head-to-tail" formation. This study successfully explains many previously observed experimental puzzles, such as the multimodal distribution of GBs and the abundance of GB misorientation angles of ∼30°. Besides, this study also showed that the formation energy of GBs is less sensitive to Θ, although the twin boundaries are slightly more stable than others.

    For several years, Nebraska Public Power District`s (NPPD) Gerald Gentleman Station Unit 1 (GGS1) has experienced boiler problems. Specifically, Unit 1 has had difficulty achieving design main steam and reheat steam temperatures. In addition, the economizer exit gas temperature has been too high, and the reheat surface has become routinely fouled. To determine the cause of these problems and to find possible solutions, NPPD contracted with a boiler manufacturer to review results of a recent performance test on the boiler and offer possible solutions. Some of the solutions offered by the boiler manufacturer were unrealistic, while others offered some promise. In early 1994, NPPD and Performance Engineering, Inc. (PEI) reviewed the results of the boiler manufacturer using a PEPSE (Performance Evaluation of Power System Efficiencies) model originally developed by NPPD and later modified by PEI. In addition, solutions not offered by the boiler manufacturer were studied. Results of the PEPSE study showed that increases to the reheat and superheat surface areas would increase the steam temperatures to the design levels while decreasing the gas temperature leaving the economizer. However, the studies also showed that keeping the surfaces clean would produce the same effect as adding more area without the capital investment. The results of the PEPSE study on GGS1 are presented and solutions are offered. A discussion of the PEPSE model and modeling techniques used for this study are also presented.

  16. Plastic traits of an exotic grass contribute to its abundance but are not always favourable.

    Full Text Available In herbaceous ecosystems worldwide, biodiversity has been negatively impacted by changed grazing regimes and nutrient enrichment. Altered disturbance regimes are thought to favour invasive species that have a high phenotypic plasticity, although most studies measure plasticity under controlled conditions in the greenhouse and then assume plasticity is an advantage in the field. Here, we compare trait plasticity between three co-occurring, C(4 perennial grass species, an invader Eragrostis curvula, and natives Eragrostis sororia and Aristida personata to grazing and fertilizer in a three-year field trial. We measured abundances and several leaf traits known to correlate with strategies used by plants to fix carbon and acquire resources, i.e. specific leaf area (SLA, leaf dry matter content (LDMC, leaf nutrient concentrations (N, C:N, P, assimilation rates (Amax and photosynthetic nitrogen use efficiency (PNUE. In the control treatment (grazed only, trait values for SLA, leaf C:N ratios, Amax and PNUE differed significantly between the three grass species. When trait values were compared across treatments, E. curvula showed higher trait plasticity than the native grasses, and this correlated with an increase in abundance across all but the grazed/fertilized treatment. The native grasses showed little trait plasticity in response to the treatments. Aristida personata decreased significantly in the treatments where E. curvula increased, and E. sororia abundance increased possibly due to increased rainfall and not in response to treatments or invader abundance. Overall, we found that plasticity did not favour an increase in abundance of E. curvula under the grazed/fertilized treatment likely because leaf nutrient contents increased and subsequently its' palatability to consumers. E. curvula also displayed a higher resource use efficiency than the native grasses. These findings suggest resource conditions and disturbance regimes can be manipulated to

    Necrotizing fasciitis of the head and neck is an uncommon, progressive, destructive soft tissue infection of mixed aerobic and anaerobic organisms, having high mortality if left untreated (22 to 100 per cent). This study makes an attempt to analyse various factors and management methods determining the overall prognosis. A retrospective analysis of all cases of necrotizing fasciitis involving the head and neck, with exclusion of those involving the eyelid and the scalp, was undertaken. Various parameters such as demography, aetiology, complications, management and outcome were studied. Males outnumbered the females with the latter having a greater risk of involvement after 60 years. Odontogenic infection was the primary source of infection. Anaerobes were cultured in seven out of 17 cases, with six others showing mixed Gram positive and Gram negative organisms. Anaemia was the most commonly associated illness, with diabetes affecting four out of 17 cases. Aggressive surgical debridement with triple antibiotic therapy was used in the management of necrotizing fasciitis with an overall mortality of 11.8 per cent. Patients having late referral, anaemia and one or other complication had increased duration of total hospital stay. Better results can be obtained with proper control of infection by early diagnosis, aggressive surgical debridement and triple antibiotic therapy, along with timely control of complications and associated illnesses.

  18. Natural selection can favour ‘irrational’ behaviour

    Understanding decisions is the fundamental aim of the behavioural sciences. The theory of rational choice is based on axiomatic principles such as transitivity and independence of irrelevant alternatives (IIA). Empirical studies have demonstrated that the behaviour of humans and other animals often seems irrational; there can be a lack of transitivity in choice and seemingly irrelevant alternatives can alter decisions. These violations of transitivity and IIA undermine rational choice theory. However, we show that an individual that is maximizing its rate of food gain can exhibit failure of transitivity and IIA. We show that such violations can be caused because a current option may disappear in the near future or a better option may reappear soon. Current food options can be indicative of food availability in the near future, and this key feature can result in apparently irrational behaviour. PMID:24429682

    It is universally accepted that high-risk human papillomavirus (HR-HPV) is the cause of cervical dysplasia and cancer. More recently, it has been shown that HPV is also a marker of clinical outcome in oropharyngeal cancer. However, contemporary information is lacking on both the prevalence of HPV infection in vulvar cancer (VSCC), its precursor lesion, vulvar intraepithelial neoplasia (VIN) and the influence of HPV-status on the prognosis of this malignancy. We have conducted a detailed population-based study to examine rates of progression of VIN to VSCC, type-specific HPV prevalence in vulvar disease and the influence of HPV status on clinical outcome in VSCC. We observed that the age at which women are diagnosed with VSCC is falling and there is a significant time gap between first diagnosis of VIN and progression to invasive disease. HR-HPV infection was detected in 87% (97/112) cases of VIN and 52% cases (32/62) of VSCC. The presence of HR-HPV in squamous intraepithelial lesion was associated with lower rates of progression to invasive cancer (hazard ratio, 0.22, p = 0.001). In the adjusted analysis, HR-HPV was associated with improved progression-free survival of VSCC compared to those with HPV negative tumours (hazard ratio, 0.32, p = 0.02).

    2013-01-01

    Here, we studied how protist predation affects cooperation in the opportunistic pathogen bacterium Pseudomonas aeruginosa, which uses quorum sensing (QS) cell-to-cell signalling to regulate the production of public goods. By competing wild-type bacteria with QS mutants (cheats), we show that a functioning QS system confers an elevated resistance to predation. Surprisingly, cheats were unable to exploit this resistance in the presence of cooperators, which suggests that resistance does not appear to result from activation of QS-regulated public goods. Instead, elevated resistance of wild-type bacteria was related to the ability to form more predation-resistant biofilms. This could be explained by the expression of QS-regulated resistance traits in densely populated biofilms and floating cell aggregations, or alternatively, by a pleiotropic cost of cheating where less resistant cheats are selectively removed from biofilms. These results show that trophic interactions among species can maintain cooperation within species, and have further implications for P. aeruginosa virulence in environmental reservoirs by potentially enriching the cooperative and highly infective strains with functional QS system.

    Owing to the present global biodiversity crisis, the biodiversity-stability relationship and the effect of biodiversity on ecosystem functioning have become major topics in ecology. Biodiversity is a complex term that includes taxonomic, functional, spatial and temporal aspects of organismic diversity, with species richness (the number of species) and evenness (the relative abundance of species) considered among the most important measures. With few exceptions (see, for example, ref. 6), the majority of studies of biodiversity-functioning and biodiversity-stability theory have predominantly examined richness. Here we show, using microbial microcosms, that initial community evenness is a key factor in preserving the functional stability of an ecosystem. Using experimental manipulations of both richness and initial evenness in microcosms with denitrifying bacterial communities, we found that the stability of the net ecosystem denitrification in the face of salinity stress was strongly influenced by the initial evenness of the community. Therefore, when communities are highly uneven, or there is extreme dominance by one or a few species, their functioning is less resistant to environmental stress. Further unravelling how evenness influences ecosystem processes in natural and humanized environments constitutes a major future conceptual challenge.

    Full Text Available In this work, we provide two case studies on interoperability and transfer of knowledge in the environment of acompany dealing with plant protection. We find that the area of plant protection is highly oriented on workingwith knowledge. In this case interoperability of knowledge can play an important role in acquiring knowledgefrom different environments to solve specific problem in companies dealing with plant protection. Nevertheless,the concept of interoperability is well-developed on the level of data and information only.We stem from our previous works, where we defined a logical concept for the interoperability of knowledge onthe level of knowledge units. The objective of this work is to show how to apply our process model ofknowledge interoperability in a particular plant protection company. Two case studies are provided in order todemonstrate distinguishing between simple knowledge transfer and knowledge interoperability.

    Full Text Available The study of the world’s verbal arts offers an opportunity to consider ways that computational analysis and modeling of narratives may lead to new understandings of how they are constructed, their dynamics and relationships. Similarly, as corpus linguistics operations must define metrics, it offers an occasion to review basic interpretive concepts such as “units of analysis, context, and genre." My essay begins with an admittedly cursory overview from a novice perspective of what capabilities corpus linguistics currently possesses for the analysis and modeling of narratives. Consideration is given to the epistemological issue in the social sciences with the positivistic prescription or empiricist description of units of analysis and the potential pitfalls or advantages corpus linguistics encounters in searching for adequate equivalent terms. This review leads naturally to reflection on the crucial determinative action of context on meaning and the extent to which current computational interfaces are able to account for and integrate into global analysis of linguistic and performance dimensions such as performer, intonation, gesture, diction, idioms and figurative language, setting, audience, time, and occasion. As a tentative conclusion from this review, it can be stated that artificial intelligence for modeling narratives or devising narrative algorithms must develop capacities to account for performance dimensions in order to fulfill their analytical potential.

    Full Text Available Digoxin is used for heart failure associated to systolic dysfunction and high ventricular rate. It has a narrow therapeutic range and intoxication may occur due to drug interactions or comorbidities. The aim of this work was to study digoxin use in a public health unit delineating the profile of patients susceptible to digitalis intoxication. Medical records belonging to patients admitted to the cardiomyopathy ward of the health unit (2009-2010 and in use of digoxin were analyzed. Among 647 patients admitted, 185 individuals using digoxin and possessed records available. The registration of plasma digoxin concentration was found in 80 records and it was out of the therapeutic range in 42 patients (52.5%. This group of individuals was constituted mainly by males patients (79%, functional class III of heart failure (65%, exhibiting renal failure (33%. The evaluated sample reflects the epidemiology of heart failure in Brazil and, although pharmacotherapy had been according to Brazilian Guidelines, apparently the monitoring was not performed as recommended. This work highlighs the necessity of plasma digoxin constant monitoring during pharmacotherapy and the development of protocols that enable a safer use, especially in male patients, functional class III and with renal dysfunction.

  13. Cost-minimization analysis favours intravenous ferric carboxymaltose over ferric sucrose for the ambulatory treatment of severe iron deficiency.

    Directory of Open Access Journals (Sweden)

    Xavier Calvet

    Full Text Available OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM allows administration of larger iron doses than iron sucrose (IS in each infusion (1000 mg vs. 200 mg. As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM. A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.

    Flowering times of plants are important life-history components and it has previously been hypothesized that flowering phenologies may be currently subject to natural selection or be selectively neutral. In this study we reviewed the evidence for phenotypic selection acting on flowering phenology using ordinary and phylogenetic meta-analysis. Phenotypic selection exists when a phenotypic trait co-varies with fitness; therefore, we looked for studies reporting an association between two components of flowering phenology (flowering time or flowering synchrony) with fitness. Data sets comprising 87 and 18 plant species were then used to assess the incidence and strength of phenotypic selection on flowering time and flowering synchrony, respectively. The influence of dependence on pollinators, the duration of the reproductive event, latitude and plant longevity as moderators of selection were also explored. Our results suggest that selection favours early flowering plants, but the strength of selection is influenced by latitude, with selection being stronger in temperate environments. However, there is no consistent pattern of selection on flowering synchrony. Our study demonstrates that phenotypic selection on flowering time is consistent and relatively strong, in contrast to previous hypotheses of selective neutrality, and has implications for the evolution of temperate floras under global climate change. © 2011 Blackwell Publishing Ltd/CNRS.

    The pollen grains of Quercus spp. (oak trees) are allergenic. This study investigates airborne Quercus pollen in SW Spain with the aim identifying favourable conditions for atmospheric transport and potential sources areas. Two types of Quercus distribution maps were produced. Airborne Quercus pollen concentrations were measured at three sites located in the Extremadura region (SW Spain) for 3 consecutive years. The seasonal occurrence of Quercus pollen in the air was investigated, as well as days with pollen concentrations ≥80Pm(-3). The distance that Quercus pollen can be transported in appreciable numbers was calculated using clusters of back trajectories representing the air mass movement above the source areas (oak woodlands), and by using a state-of-the-art dispersion model. The two main potential sources of Quercus airborne pollen captured in SW Spain are Q. ilex subsp. ballota and Q. suber. The minimum distances between aerobiological stations and Quercus woodlands have been estimated as: 40km (Plasencia), 66km (Don Benito), 62km (Zafra) from the context of this study. Daily mean Quercus pollen concentration can exceed 1,700Pm(-3), levels reached not less than 24 days in a single year. High Quercus pollen concentration were mostly associated with moderate wind speed events (6-10ms(-1)), whereas that a high wind speed (16-20ms(-1)) seems to be associated with low concentrations.

    The Damintun (大民屯) depression,a small (about 800 km2 in area) subunit in the Bohai (渤海) Bay basin,hosts nearly 2×108t of high-wax oils with wax contents up to 60%. The high-wax oils have high consolidation temperatures and viscosities.The high-wax oils were generated from the fourth member of the Shahejie Formation (Es4),which is also important source rocks for oils in other subunits of the Bohai Bay basin.Yet high-wax oils have not been found in significant volumes elsewhere in the Bohai Bay basin.Geological conditions favourable for high-wax oil enrichment were studied.This study shows that the unusual concentrations of high-wax oils in the depression seem to result from at least three different factors: (1) the presence of organic-matter rich source rocks which were prone to generate wax-rich hydrocarbons; (2) the formation of early overpressures which increased the expulsion efficiency of waxy hydrocarbons; and (3) reductions in subsidence rate and basal heat flows,which minimized the thermal cracking of high molecular-weight (waxy) hydrocarbons,and therefore prevented the high-wax oils from being transformed into less waxy equivalents.

    Pertussis is a common serious illness of childhood that can be controlled by immunization. It is a unique disease in that it is clinically manifested more often in females than in males. In the 20th century the mortality from pertussis has decreased steadily in both the United Kingdom and the United States. This decline in death rate was well underway prior to the introduction of pertussis vaccine but was accelerated after vaccine use became widespread. In recent years the case fatality rate in the United States has been considerably greater than that in the United Kingdom. One obvious reason for this difference is the difference in age-specific attack rates in the two nations. Available data also suggest that recent pertussis deaths in infants in England and Wales may frequently be reported as due to respiratory diseases other than pertussis. Although it is frequently suggested by some observers, there is no evidence that the incidence of pertussis was declining prior to the widespread use of vaccine. All available evidence indicates that pertussis vaccine use in both the United Kingdom and the United States was responsible for a drastic reduction in the magnitude of both endemic and epidemic pertussis. Decreased utilization of pertussis vaccine in England and Wales beginning in 1975 resulted in two major epidemics of pertussis in 1977-1979 and 1982-1983. Moderate local and systemic reactions commonly occur following pertussis immunization. These reactions appear to be less common and less severe in the United Kingdom than in the United States, but in contrast to recent studies in the United States, there are no recent quantitative studies in the United Kingdom. There are virtually no data available in the United States on the incidence of serious neurologic disease resulting from pertussis immunization. In contrast, the recently published findings of the NCES, a case-control study of national scope, have allowed attributable risk estimates of serious neurologic

    Aberrant mineralization of soft connective tissues (ectopic calcification) may occur as a frequent age-related complication. Still, it remains unclear the role of mesenchymal cell donor's age and of replicative senescence on ectopic calcification. Therefore, the ability of cells to deposit in-vitro hydroxyapatite crystals and the expression of progressive ankylosis protein homolog (ANKH), ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), tissue non specific alkaline phosphatase (TNAP) and osteopontin (OPN) have been evaluated in human dermal fibroblasts derived from neonatal (nHDF) and adult (aHDF) donors (ex-vivo ageing model) or at low and high cumulative population doublings (CPD) up to replicative senescence (in-vitro ageing model). This study demonstrates that: 1) replicative senescence favours hydroxyapatite formation in cultured fibroblasts; 2) donor's age acts as a major modulator of the mineralizing potential of HDF, since nHDF are less prone than aHDF to induce calcification; 3) donor's age and replicative senescence play in concert synergistically increasing the calcification process; 4) the ANKH+ENPP1/TNAP ratio, being crucial for pyrophosphate/inorganic phosphate balance, is greatly influenced by donor's age, as well as by replicative senescence, and regulates mineral deposition; 5) OPN is only modulated by replicative senescence.

  4. Is earthquake activity along the French Atlantic margin favoured by local rheological contrasts?

    The seismological study of recent seismic crises near Oleron Island confirms the coexistence of an extensional deformation and a transtensive regime in the Atlantic margin of France, which is different from the general western European stress field corresponding to a strike-slip regime. We argue that the switch of the principal stress axes σ1/σ2 in a NW-SE vertical plane is linked with the existence of crustal heterogeneities. Events of magnitude larger than 5 sometimes occur along the Atlantic margin of France, such as the 7 September 1972 (ML = 5.2) earthquake near Oleron island and the 30 September 2002 (ML = 5.7) Hennebont event in Brittany. To test the mechanism of local strain localization, we model the deformation of the hypocentral area of the Hennebont earthquake using a 3D thermo-mechanical finite element code. We conclude that the occurrence of moderate earthquakes located in limited parts of the Hercynian shear zones (as the often reactivated swarms near Oleron) could be due to local reactivation of pre-existing faults. These sporadic seismic ruptures are favoured by stress concentration due to rheological heterogeneities.

    We present a census of blue horizontal branch (BHB) and blue straggler (BS) stars belonging to dwarf galaxies and globular clusters, and compare these counts to that of the Milky Way stellar halo. We find, in agreement with earlier studies, that the ratio of BS-to-BHB stars in these satellite populations is dependent on stellar mass. Dwarf galaxies show an increasing BS-to-BHB ratio with luminosity. In contrast, globular clusters display the reverse trend, with N_BS/N_BHB (< 1) decreasing with luminosity. The faintest (L < 10^5 L_Sun) dwarfs have similar numbers of BS and BHB stars (N_BS/N_BHB ~ 1), whereas more massive dwarfs tend to be dominated by BS stars (N_BS/N_BHB ~ 2-40). We find that the BS-to-BHB ratio in the stellar halo is relatively high (N_BS/N_BHB ~ 5-6), and thus inconsistent with the low ratios found in both ultra-faint dwarfs and globular clusters. Our results favour more massive dwarfs as the dominant "building blocks" of the stellar halo, in good agreement with current predictions fr...

    The aim of this study was to characterize the learning styles of different groups of athletes grouped according to level of performance and sport. Seventy-one male athletes completed a questionnaire on learning styles at the beginning of the 2008-2009 training season. Learning styles were assessed using the Honey-Alonso Learning Styles Questionnaire, and were also converted into learning styles described by Kolb. The Honey-Alonso learning styles were compared among the various groups using one-way analysis of variance, and the Kolb learning styles that were most favoured using a chi-square test. Pearson's correlation coefficient was used to verify the relationships between variables. No significant differences were observed in learning styles between different sports and physical activities. Years of experience did not correlate strongly with learning styles. With respect to level of performance, the pragmatic component was significantly lower in professional athletes than amateur and recreational athletes. These characteristics of learning styles preferred by the athletes should help coaches and physical trainers to reflect on their role as educators in the context of planning sports training.

  7. Living with strangers: direct benefits favour non-kin cooperation in a communally nesting bird.

    The greater ani (Crotophaga major), a Neotropical cuckoo, exhibits an unusual breeding system in which several socially monogamous pairs lay eggs in a single nest and contribute care to the communal clutch. Cooperative nesting is costly-females compete for reproduction by ejecting each other's eggs-but the potential direct or indirect fitness benefits that might accrue to group members have not been identified. In this study, I used molecular genotyping to quantify patterns of genetic relatedness and individual reproductive success within social groups in a single colour-banded population. Microsatellite analysis of 122 individuals in 49 groups revealed that group members are not genetic relatives. Group size was strongly correlated with individual reproductive success: solitary pairs were extremely rare and never successful, and nests attended by two pairs were significantly more likely to be depredated than were nests attended by three pairs. Egg loss, a consequence of reproductive competition, was greater in large groups and disproportionately affected females that initiated laying. However, early-laying females compensated for egg losses by laying larger clutches, and female group members switched positions in the laying order across nesting attempts. The greater ani, therefore, appears to be one of the few species in which cooperative breeding among unrelated individuals is favoured by direct, shared benefits that outweigh the substantial costs of reproductive competition.

  8. Hindered aryl bromides for regioselective palladium-catalysed direct arylation at less favourable C5-carbon of 3-substituted thiophenes

    Full Text Available The use of the congested aryl bromide 2-bromo-1,3-dichlorobenzene as coupling partner allows to modify the regioselectivity of the arylation of 3-substituted thiophene derivatives in favour of carbon C5. The coupling of this aryl bromide with a variety of 3-substituted thiophenes gave in all cases the desired 5-arylation products in moderate to good yields using only 0.5 mol % of a phosphine-free and air-stable palladium catalyst. Then, from these 5-arylthiophenes, a second palladium-catalysed C–H bond functionalization at C2 of the thiophene ring allows the synthesis of 2,5-diarylthiophenes with two different aryl units.

    To determine the epidemiology of fever on the intensive care unit (ICU). Prospective, observational study. Nine-bed general ICU in a 500-bed tertiary care inner city institution. 100 consecutive admissions of 93 patients over a 4-month period between July and October 1996. All patients were seen and examined by one investigator within 24 h of ICU admission. Patients were followed up on a daily basis throughout their ICU stay, and all clinical and laboratory data were recorded during the admission. Fever (core temperature > or = 38.4 degrees C) was present in 70% of admissions, and it was caused by infective and non-infective processes in approximately equal number. Most fevers occurred early in the course of the admission, within the first 1-2 days, and most lasted less than 5 days. The median Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15 (+/- 0.6). The 70 episodes associated with fever at any time were associated with a significantly higher APACHE II score on admission than the afebrile episodes (15.8 +/- 6.1 vs 12.1 +/- 6.7, p = 0.04). The most common cause of non-infective fever was in the group designated post-operative fever (n = 34). All the patients in the post-operative fever group were febrile on day 0 or day 1; their mean admission APACHE score was 12.4 (+/- 4.4) compared to 15.9 (+/- 7.1) for the remaining patients (p = 0.01). Fever alone was not associated with a higher mortality: 26/70 (37%) of febrile patients died, compared to 8/30 (27%) of afebrile patients, (chi 2 = 1.23, p = 0.38). Prolonged fever (> 5 days) occurred in 16 patients. In 13 cases, fever was due to infection, and in the remaining 3 both infective and non-infective processes occurred concurrently. The mortality in the group with prolonged fever was 62.5% (10/16) compared to 29.6% (16/54) in patients with fever of less than 5 days' duration, a highly significant difference (p Fever is a common event on the intensive care unit.

    Previous studies have failed to identify mutations in the Wilson's disease gene ATP7B in a significant number of clinically diagnosed cases. This has led to concerns about genetic heterogeneity for this condition but also suggested the presence of unusual mutational mechanisms. We now present our findings in 181 patients from the United Kingdom with clinically and biochemically confirmed Wilson's disease. A total of 116 different ATP7B mutations were detected, 32 of which are novel. The overall mutation detection frequency was 98%. The likelihood of mutations in genes other than ATP7B causing a Wilson's disease phenotype is therefore very low. We report the first cases with Wilson's disease due to segmental uniparental isodisomy as well as three patients with three ATP7B mutations and three families with Wilson's disease in two consecutive generations. We determined the genetic prevalence of Wilson's disease in the United Kingdom by sequencing the entire coding region and adjacent splice sites of ATP7B in 1000 control subjects. The frequency of all single nucleotide variants with in silico evidence of pathogenicity (Class 1 variant) was 0.056 or 0.040 if only those single nucleotide variants that had previously been reported as mutations in patients with Wilson's disease were included in the analysis (Class 2 variant). The frequency of heterozygote, putative or definite disease-associated ATP7B mutations was therefore considerably higher than the previously reported occurrence of 1:90 (or 0.011) for heterozygote ATP7B mutation carriers in the general population (P Wilson's disease of 1:30 000 (P = 0.00093). Our study provides strong evidence for monogenic inheritance of Wilson's disease. It also has major implications for ATP7B analysis in clinical practice, namely the need to consider unusual genetic mechanisms such as uniparental disomy or the possible presence of three ATP7B mutations. The marked discrepancy between the genetic prevalence and the number of

  11. Parametric design studies of toroidal magnetic energy storage units

    Herring, J. Stephen

    Superconducting magnetic energy storage (SMES) units have a number of advantages as storage devices. Electrical current is the input, output and stored medium, allowing for completely solid-state energy conversion. The magnets themselves have no moving parts. The round trip efficiency is higher than those for batteries, compressed air or pumped hydro. Output power can be very high, allowing complete discharge of the unit within a few seconds. Finally, the unit can be designed for a very large number of cycles, limited basically by fatigue in the structural components. A small systems code was written to produce and evaluate self-consistent designs for toroidal superconducting energy storage units. The units can use either low temperature or high temperature superconductors. The coils have D shape where the conductor and its stabilizer/structure is loaded only in tension and the centering forces are borne by a bucking cylinder. The coils are convectively cooled from a cryogenic reservoir in the bore of the coils. The coils are suspended in a cylindrical metal shell which protects the magnet during rail, automotive or shipboard use. It is important to note that the storage unit does not rely on its surroundings for structural support, other than normal gravity and inertial loads. Designs are presented for toroidal energy storage units produced by the systems code. A wide range of several parameters have been considered, resulting in units storing from 1 MJ to 72 GJ. Maximum fields range from 5 T to 20 T. The masses and volumes of the coils, bucking cylinder, coolant, insulation and outer shell are calculated. For unattended use, the allowable operating time using only the boiloff of the cryogenic fluid for refrigeration is calculated. For larger units, the coils were divided into modules suitable for normal truck or rail transport.

    Hydroelectric generator unit is a complex mechanical system which is composed of hydraulic turbine and electric generator. Rotary system is supported by the bearing bracket and the reinforced concrete structures, and vibration problem can't be avoided in the process of operating. Many large-scale hydroelectric units have been damaged because of the vibration problem in recent years. As the increase of the hydraulic turbine unit capacity and water head, the safe operation of hydraulic turbine has become a focus research in many countries. The operating characteristics of the hydraulic turbine have obvious differences at different working conditions. Based on the combination of field measurement and theoretical calculation, this paper shows a deep research on the safe operation of a large-scale Francis turbine unit. Firstly, the measurements of vibration, swing, pressure fluctuation and noise were carried out at 4 different heads. And also the relationships between vibrations and pressure fluctuations at different heads and working conditions were analysed deeply. Then the scientific prediction of safe operation for the unit at high head were done based on the CFD numerical calculation. Finally, this paper shows the division of the operating zone for the hydroelectric unit. According to the experimental results (vibrations, swings, pressure fluctuations and noise) as well as the theoretical results, the operating zone of the unit has been divided into three sections: prohibited operating zone, transition operating zone and safe operating zone. After this research was applied in the hydropower station, the security and economic efficiency of unit increased greatly, and enormous economic benefits and social benefits have been obtained.

    This study compared physical and visual accessibilities and their associations with staff perception and interaction behaviors in 2 intensive care units (ICUs) with open-plan and racetrack layouts. For the study, physical and visual accessibilities were measured using the spatial analysis techniques of Space Syntax. Data on staff perception were collected from 81 clinicians using a questionnaire survey. The locations of 2233 interactions, and the location and length of another 339 interactions in these units were collected using systematic field observation techniques. According to the study, physical and visual accessibilities were different in the 2 ICUs, and clinicians' primary workspaces were physically and visually more accessible in the open-plan ICU. Physical and visual accessibilities affected how well clinicians' knew their peers and where their peers were located in these units. Physical and visual accessibilities also affected clinicians' perception of interaction and communication and of teamwork and collaboration in these units. Additionally, physical and visual accessibilities showed significant positive associations with interaction behaviors in these units, with the open-plan ICU showing stronger associations. However, physical accessibilities were less important than visual accessibilities in relation to interaction behaviors in these ICUs. The implications of these findings for ICU design are discussed.

    This report expands on a previous National Renewable Energy Laboratory (NREL) technical report (Lowder et al. 2015) that focused on the United States' unique approach to distributed generation photovoltaics (DGPV) support policies and business models. While the focus of that report was largely historical (i.e., detailing the policies and market developments that led to the growth of DGPV in the United States), this report looks forward, narrating recent changes to laws and regulations as well as the ongoing dialogues over how to incorporate distributed generation (DG) resources onto the electric grid. This report also broadens the scope of Lowder et al. (2015) to include additional countries and technologies. DGPV and storage are the principal technologies under consideration (owing to market readiness and deployment volumes), but the report also contemplates any generation resource that is (1) on the customer side of the meter, (2) used to, at least partly, offset a host's energy consumption, and/or (3) potentially available to provide grid support (e.g., through peak shaving and load shifting, ancillary services, and other means).

    Full Text Available The geoecological landscape observation allows the analysis of geosystems fragmentation in small areas or a diagnosis of a particular environment or biome. This geosystemic approach permits the integration of elements that constitutes the environment, allowing the interaction and interdependence analysis of social and ecological elements. The main goal of this work was to elaborate a map of landscape units and a territorial planning for Pantanal biome, using data generated by the Brazilian Institute of Geography and Statistics (IBGE corresponding to morphometric relief units, geology, soils and agricultural capability; the land cover and land use map developed by the Brazilian Agricultural Research Corporation (EMBRAPA and the maps of flooded areas and spatial variability of the Pantanal biome. From the crosstab between altitude, slope, spatial variability map and geology we identified 16 landscape units. Additionally, the analysis of Pantanal biome environmental vulnerability of the landscape units considering different types of vegetation, topography and soils units showed that Pantanal has an intermediate environmental fragility, located mainly in the alluvial deposition areas of the Taquari river and in flood plains with altitude between 50 and 250 meters.

    Landing and supporting a permanent outpost on a planetary surface represents humankind's capability to expand its own horizons and challenge current technology. With this in mind, habitability of these structures becomes more essential given the longer durations of the missions. The purpose of this evaluation was to obtain preliminary human-in-the-loop performance data on the Habitat Demonstration Unit (HDU) in a Pressurized Excursion Module (PEM) configuration during a 14-day simulated lunar exploration field trial and to apply this knowledge to further enhance the habitat's capabilities for forward designs. Human factors engineers at the NASA/Johnson Space Center's Habitability and Human Factors Branch recorded approximately 96 h of crew task performance with four work stations. Human factors measures used during this study included the NASA Task Load Index (TLX) and customized post questionnaires. Overall the volume for the PEM was considered acceptable by the crew; however; the habitat's individual work station volume was constrained when setting up the vehicle for operation, medical operations, and suit maintenance while general maintenance, logistical resupply, and geo science was considered acceptable. Crew workload for each station indicated resupply as being the lowest rated, with medical operations, general maintenance, and geo science tasks as being light, while suit maintenance was considered moderate and general vehicle setup being rated the highest. Stowage was an issue around the habitat with the Space Exploration Vehicle (SEV) resupply stowage located in the center of the habitat as interfering with some work station volumes and activities. Ergonomics of the geo science station was considered a major issue, especially with the overhead touch screens.

    The effect of the obstructive sleep apnea syndrome on energy expenditure is controversial. The objective of this study was to assess the relationship between 24-hr energy expenditure or sleeping metabolic rate and features of the obstructive sleep apnea. Twenty-four apneic men took part in this cross-sectional study and were classified in quartiles of nocturnal desaturation severity, i.e. of percentage total sleep time with SaO2 hydrodensitometry. During the stay in the respiratory chamber, urine was collected to assess catecholamine concentration and percentage recording time with SaO2 < 90% (%TRT SaO2 < 90%) was measured with nocturnal oximetry. Mean fat free mass and fat mass were greater in quartile 4 than in quartile 1 (P < 0.05). %TRT SaO2 < 90% was higher in quartile 4 than in other quartiles (P < 0.0001). 24-hr energy expenditure and sleeping metabolic rate were similar among quartiles. However, when expressed on a per kg body weight basis (kcal/kg), these variables were negatively correlated with the %TRT SaO2 < 90% in the whole group (r = -0.46 and -0.48, respectively, P < 0.05). %TRT SaO2 < 90% was found to be a predictor of sleeping metabolic rate which explained, together with fat mass and fat free mass, 86% of this variance (P < 0.05). In apneic men energy expenditure relative to body weight decreases with increasing severity of oxygen desaturation which could favour a positive energy balance.

The paper reviews the principal energy resources used for electricity production, considers the changing regulatory environment for the electricity industry, and describes government policies that have been used to promote green electricity in the United States, with an emphasis on measures adopted by state governments. Factors influencing the development of green power markets are also discussed, including underlying economic issues, public policy measures, the regulatory environment, external costs, and subsidies. Without significant increases in fossil fuel prices, much more stringent environmental regulations, or significant changes in electricity customer preferences, green electricity markets are likely to develop slowly in the United States.

    Vaccenic acid (VA) is a ruminant-derived trans-fat and precursor of conjugated linoleic acid (CLA). The objective of the present study was to explore the effects of VA on immune function in a model of the metabolic syndrome, JCR:LA-cp rats. Lean (2:1 mix of +/cp and +/+) and obese (cp/cp) rats, aged 8 weeks, were fed a control (0% VA) or a VA diet (1.5% (w/w) VA) for 3 weeks (twenty rats per group). Splenocytes and mesenteric lymph node (MLN) immune cell phenotypes (flow cytometry), ex vivo cytokine production (ELISA) and phospholipid fatty acid concentrations were measured. Obese rats had higher proportions of splenic macrophages, total T-cells, helper T-cells (total and percentage CD25+), cytotoxic T-cells (total and percentage CD25+) and produced higher concentrations of IL-6 to concanavalin A (ConA) compared with lean rats. Obese rats had lower proportions of MLN T-cells, new T-cells (CD3+CD90+) and cytotoxic T-cells, but higher proportions of helper cells that were CD45RC+, CD25+ and CD4lo, and produced higher concentrations of IL-2, IL-10, interferon gamma and TNFalpha in response to ConA compared with lean rats. VA was higher in plasma phospholipids and both VA and CLA (cis-9, trans-11) were higher in MLN phospholipids compared with control-fed rats. Lean VA-fed rats had lower proportions of MLN and splenocyte CD45RC+ helper cells, and helper T-cells. Splenocytes from VA-fed rats produced 16-23% less IL-2, IL-10 and TNFalpha compared with controls. VA normalised production of MLN IL-2 and TNFalpha in obese rats to levels similar to those seen in lean rats. These results indicate that dietary VA favourably alters the pro-inflammatory tendency of mesenteric lymphocytes from JCR:LA-cp rats.

    Irisin is a myokine, which is mainly inversely associated with the risk for non-communicable diseases. Irisin improves cellular energy metabolism by uncoupling the mitochondrial respiratory chain resulting in increased energy expenditure using lipids. To date potential associations between irisin concentration and lipid profile are poorly understood. Therefore, this investigation aimed to evaluate potential associations between irisin and lipid levels in the general population. Data of 430 men and 537 women from the population-based Study of Health in Pomerania (SHIP-TREND) with available irisin and lipid concentrations were used. Analyses of variance, linear and logistic regression models adjusted for age, HBA1c, waist circumference, physical activity, smoking, alcohol consumption, systolic blood pressure, ALAT were calculated. We detected significantly inverse associations between irisin and circulating levels of total [beta coefficient 0.21 (standard error 0.08), p = 0.01], low-density cholesterol [-0.16 (0.07), p = 0.03] and triglycerides [-0.17 (0.08), p = 0.02] for men. Females without lipid lowering medication had an inverse association between irisin and total cholesterol [-0.12 (0.06), p = 0.05]. Further, male subjects with irisin concentrations in the third tertile had an increased odds for elevated low-density cholesterol [odds ratio 1.96 (95% confidence interval 1.07-3.48), p = 0.03) and triglyceride [1.95 (1.09-3.47), p = 0.02] levels, even after exclusion of subjects with lipid lowering medication. In addition, our data revealed an annual rhythm of serum irisin levels with peak levels arise in winter and summer months. This is the first investigation to report a significant association between circulating irisin and a favourable lipid profile in the general population. This may infer that higher irisin concentrations are associated with a reduced risk for non-communicable diseases.

    Traits related to flower advertisement and reward sometimes vary in a circadian way, reflecting phenotypic specialization. However, specialized flowers are not necessarily restricted to specialized pollinators. This is the case of most Silene species, typically associated with diurnal or nocturnal syndromes of pollination but usually showing complex suites of pollinators. A Silene species with mixed floral features between diurnal and nocturnal syndromes was used to test how petal opening, nectar production, scent emission and pollination success correlate in a circadian rhythm, and whether this is influenced by environmental conditions. The effect of diurnal and nocturnal visitation rates on plant reproductive success is also explored in three populations, including the effect of the pollinating seed predator Hadena sancta KEY RESULTS: The result showed that repeated petal opening at dusk was correlated with nectar secretion and higher scent production during the night. However, depending on environmental conditions, petals remain opened for a while in the morning, when nectar and pollen still were available. Pollen deposition was similarly effective at night and in the morning, but less effective in the afternoon. These results were consistent with field studies. The circadian rhythm regulating floral attractiveness and reward in S. colorata is predominantly adapted to nocturnal flower visitors. However, favourable environmental conditions lengthen the optimal daily period of flower attraction and pollination towards morning. This allows the complementarity of day and night pollination. Diurnal pollination may help to compensate the plant reproductive success when nocturnal pollinators are scarce and when the net outcome of H. sancta shifts from mutualism to parasitism. These results suggest a functional mechanism explaining why the supposed nocturnal syndrome of many Silene species does not successfully predict their pollinator guilds. © The Author 2016

    A transnational network of genetic conservation units for forest trees was recently documented in Europe aiming at the conservation of evolutionary processes and the adaptive potential of natural or man-made tree populations. In this study, we quantified the vulnerability of individual conservation units and the whole network to climate change using climate favourability models and the estimated velocity of climate change. Compared to the overall climate niche of the analysed target species populations at the warm and dry end of the species niche are underrepresented in the network. However, by 2100, target species in 33-65 % of conservation units, mostly located in southern Europe, will be at the limit or outside the species' current climatic niche as demonstrated by favourabilities below required model sensitivities of 95%. The highest average decrease in favourabilities throughout the network can be expected for coniferous trees although they are mainly occurring within units in mountainous landscapes for which we estimated lower velocities of change. Generally, the species-specific estimates of favourabilities showed only low correlations to the velocity of climate change in individual units, indicating that both vulnerability measures should be considered for climate risk analysis. The variation in favourabilities among target species within the same conservation units is expected to increase with climate change and will likely require a prioritization among co-occurring species. The present results suggest that there is a strong need to intensify monitoring efforts and to develop additional conservation measures for populations in the most vulnerable units. Also, our results call for continued transnational actions for genetic conservation of European forest trees, including the establishment of dynamic conservation populations outside the current species distribution ranges within European assisted migration schemes. © 2013 John Wiley & Sons Ltd.

  18. Study of geothermal prospects in the western United States

    Energy Technology Data Exchange (ETDEWEB)

    1976-08-20

    The commercial development potential of 13 underdeveloped geothermal prospects in the Western United States has been examined and the prospects have been ranked in order of relative potential for development on the basis of investment considerations. The following were considered in the ranking: geotechnical and engineering data, energy market accessibility, administrative constraints, and environmental and socio-economic factors. The primary ranking criterion is the unit cost of energy production expected from each prospect. This criterion is obtained principally from expected reservoir temperatures and depths. Secondary criteria are administrative constraints, environmental factors and the quality of the geotechnical data. The Roosevelt, Utah, prospect ranks first in development potential followed in order by Beowawe, Nevada; Coso Hot Springs, California; Long Valley, California; and Brady's Hot Springs, Nevada.

  1. Women’s experience of transfer from midwifery unit to hospital obstetric unit during labour: a qualitative interview study

    2012-11-01

    Full Text Available Abstract Background Midwifery units offer care to women with straightforward pregnancies, but unforeseen complications can arise during labour or soon after birth, necessitating transfer to a hospital obstetric unit. In England, 21% of women planning birth in freestanding midwifery units are transferred; in alongside units, the transfer rate is 26%. There is little high quality contemporary evidence on women’s experience of transfer. Methods We carried out a qualitative interview study, using semi-structured interviews, with women who had been transferred from a midwifery unit (freestanding or alongside in England up to 12 months prior to interview. Maximum variation sampling was used. Interviews with 30 women took place between March 2009 and March 2010. Thematic analysis using constant comparison and exploration of deviant cases was carried out. Results Most women hoped for or expected a natural birth and did not expect to be transferred. Transfer was disappointing for many; sensitive and supportive care and preparation for the need for transfer helped women adjust to their changing circumstances. A small number of women, often in the context of prolonged labour, described transfer as a relief. For women transferred from freestanding units, the ambulance journey was a “limbo” period. Women wondered, worried or were fearful about what was to come and could be passive participants who felt like they were being “transported” rather than cared for. For many this was a direct contrast with the care they experienced in the midwifery unit. After transfer, most women appreciated the opportunity to talk about their experience to make sense of what happened and help them plan for future pregnancies, but did not necessarily seek this out if it was not offered. Conclusions Transfer affects a significant minority of women planning birth in midwifery units and is therefore a concern for women and midwives. Transfer is not expected by women, but

  2. Loess studies in central United States: Evolution of concepts

    Follmer, L.R.

    1996-01-01

    Few words in the realm of earth science have caused more debate than "loess". It is a common term that was first used as a name of a silt deposit before it was defined in a scientific sense. Because this "loose" deposit is easily distinguished from other more coherent deposits, it was recognized as a matter of practical concern and later became the object of much scientific scrutiny. Loess was first recognized along the Rhine Valley in Germany in the 1830s and was first noted in the United States in 1846 along the lower Mississippi River where it later became the center of attention. The use of the name eventually spread around the world, but its use has not been consistently applied. Over the years some interpretations and stratigraphic correlations have been validated, but others have been hotly contested on conceptual grounds and semantic issues. The concept of loess evolved into a complex issue as loess and loess-like deposits were discovered in different parts of the US. The evolution of concepts in the central US developed in four indefinite stages: the eras of (1) discovery and development of hypotheses, (2) conditional acceptance of the eolian origin of loess, (3) "bandwagon" popularity of loess research, and (4) analytical inquiry on the nature of loess. Toward the end of the first era around 1900, the popular opinion on the meaning of the term loess shifted from a lithological sense of loose silt to a lithogenetic sense of eolian silt. However, the dual use of the term fostered a lingering skepticism during the second era that ended in 1944 with an explosion of interest that lasted for more than a decade. In 1944, R.J. Russell proposed and H.N. Fisk defended a new non-eolian, property-based, concept of loess. The eolian advocates reacted with surprise and enthusiasm. Each side used constrained arguments to show their view of the problem, but did not examine the fundamental problem, which was not in the proofs of their hypothesis, but in the definition of

    Against the backdrop of demographic change and economic reconfiguration, recruiting international students, especially those at tertiary level, has drawn growing attention from advanced economies as part of a broad strategy to manage highly skilled migration. This comparative study focuses on three English speaking countries receiving international students: Canada, the United States, and the United Kingdom. International student policies, in particular entry and immigration regulations, and the trends in student mobility since the late 1990s are examined drawing on secondary data. By exploring the issue from the political economy perspectives, this study identifies distinct national strategies for managing student mobility, determines key factors shaping the environment of student migration in each nation, and addresses the deficiency of human capital theory in the analysis of global competition for high skills.

    This paper presents a comparison study of workspace and dexterity of two Tricept units for Reconfigurable Parallel Kinematic Machines (RPKMs). The modular leg of RPKMs is designed and the RPKMs can be built by changing the setting of modules. A compositive kinematic model is developed accordingly. The inverse kinematics and Jacobian of these two Tricept units are analyzed. Considering workspace volume and dexterity, the effects of geometric size of some modules on the two Tricept units are discussed. In the end, comparison results of these two Tricept units are given. The comparison of two kinds of Parallel Kinematic Machines (PKMs) can be of help in the design and configuration planning of the RPKMs.

    Tamas David-Barrett

    Full Text Available The ability to create lasting, trust-based friendships makes it possible for humans to form large and coherent groups. The recent literature on the evolution of sociality and on the network dynamics of human societies suggests that large human groups have a layered structure generated by emotionally supported social relationships. There are also gender differences in adult social style which may involve different trade-offs between the quantity and quality of friendships. Although many have suggested that females tend to focus on intimate relations with a few other females, while males build larger, more hierarchical coalitions, the existence of such gender differences is disputed and data from adults is scarce. Here, we present cross-cultural evidence for gender differences in the preference for close friendships. We use a sample of ∼112,000 profile pictures from nine world regions posted on a popular social networking site to show that, in self-selected displays of social relationships, women favour dyadic relations, whereas men favour larger, all-male cliques. These apparently different solutions to quality-quantity trade-offs suggest a universal and fundamental difference in the function of close friendships for the two sexes.

    Due to the vulnerable nature of its patients, the wide use of invasive devices and broad-spectrum antimicrobials used, the intensive care unit (ICU) is often called the epicentre of infections. In the present study, we quantified the burden of hospital acquired pathology in a Romanian university hospital ICU, represented by antimicrobial agents consumption, costs and local resistance patterns, in order to identify multimodal interventional strategies. Between 1(st) January 2012 and 31(st) December 2013, a prospective study was conducted in the largest ICU of Western Romania. The study group was divided into four sub-samples: patients who only received prophylactic antibiotherapy, those with community-acquired infections, patients who developed hospital acquired infections and patients with community acquired infections complicated by hospital-acquired infections. The statistical analysis was performed using the EpiInfo version 3.5.4 and SPSS version 20. A total of 1596 subjects were enrolled in the study and the recorded consumption of antimicrobial agents was 1172.40 DDD/ 1000 patient-days. The presence of hospital acquired infections doubled the length of stay (6.70 days for patients with community-acquired infections versus 16.06/14.08 days for those with hospital-acquired infections), the number of antimicrobial treatment days (5.47 in sub-sample II versus 11.18/12.13 in sub-samples III/IV) and they increased by 4 times compared to uninfected patients. The perioperative prophylactic antibiotic treatment had an average length duration of 2.78 while the empirical antimicrobial therapy was 3.96 days in sample II and 4.75/4.85 days for the patients with hospital-acquired infections. The incidence density of resistant strains was 8.27/1000 patient-days for methicilin resistant Staphylococcus aureus, 7.88 for extended spectrum β-lactamase producing Klebsiella pneumoniae and 4.68/1000 patient-days for multidrug resistant Acinetobacter baumannii.

    Pregnancy is associated with an increase in body fat; however, excessive gestational weight gain predisposes to significant maternal and neonatal morbidity and mortality. It remains unclear whether alterations in energy homeostasis have a major influence on fat storage. To evaluate longitudinal changes in body composition and energy metabolism in healthy pregnant women. Body composition, energy expenditure and energy intake were measured longitudinally in 26 women with singleton pregnancies at 12-14 weeks, 24-26 weeks and 34-36 weeks of gestation. Fat mass (FM) and lean body mass (LBM) were measured using bio-impedance analysis, total energy expenditure (TEE) using the Sensewear Armband and energy intake through a 3-day food recall diary. Throughout pregnancy, all women remained healthy. Body weight increased by 10.8 ± 3.9 kg, from 67.3 ± 14.1 kg to 78.1 ± 13.8 kg from the first to the third trimester (P Body fat percentage increased by 4.5 ± 4.2% (P change significantly throughout pregnancy. Healthy women increase FM during pregnancy despite slight increases in TEE and no change in energy intake. This suggests that energy storage efficiency improves during pregnancy, which may be related to alterations in gut microbiota and activation of anabolic pathways during pregnancy. Clarifying factors leading to this more efficient fat and energy storing state, and the role of the pregnancy-related changes in gut microbiota, may be important for managing gestational weight gain. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available This paper focuses on Buddhism in America, an neglected area of inquiry in anthropological study. There is a need for modern ethnographic studies to shed light on historical issues, paradigms for comparative inquiry, and thus, explore the impact of Buddhism on modern American society (Glazier, 1997. The enormous growth of Buddhism in the last quarter century (Smith, 2002 makes this an especially pertinent topic in American anthropology. We utilize Glazier’s model to add Buddhism as a topic in the area of modernity studies. This is a preliminary study of the nature of Buddhism in America. We conducted participant observation with a Buddhist meditation group in a north eastern state in the US for four months in the spring of 2010. Based on our preliminary ethnographic data, we believe that a unique perspectives of Buddhism in America can be identified: non-religious and therapeutic involvement or use of Buddhism. Also, new forms of practice become evident, for example, ‘walking meditation’ and ‘bowing to other Buddhists,’ are identified as characteristics of Buddhism in America. It is interesting to note that at the end of meditation sessions, participants not only bow to the Buddha statue, but also bow to each other. This is a unique ritual dynamic which appears to be consistent with the worldview of American people - being equal and individual. The meditation group also practiced ‘walking meditation’ which is easy to do in everyday life. Additionally, we observed that American meditation rooms provide additional cushions to sit on which are a further element, along with walking meditation, which help American beginners to meditate more easily. These study observations shed light on the current situation by providing new lenses from which to understand and focus on different ritual performances/interpretations of Buddhism, and their meanings and functions in society. The most important reflection is that religious change is not an

    Full Text Available Background & Aims of the Study: Nowadays, heat stress is one of the most harmful physical agents in workplaces. According to the consequences of heat stress and have no information about it in Qom dry cleaner units, Iran, this study have been designed to evaluate the heat stress among workers of dry cleaner units in Qom province of Iran, in Jul-Aug 2011. Materials & Methods: This cross-sectional study was conducted in 113 units of active dry cleaner units. WBGT (Wet Bulb Globe Temperature index was selected for heat stress evaluation. In order to measure the requisite parameters, WBGT meter made of Casella Company had been used according to ISO 7243. Data had been analyzed according to Occupational Exposure Limits (OELs with SPSS V.16, using analysis of variance, independent T and LSD tests. Results: The average of WBGT index in Qom dry cleaner units of Iran were 28.98±1.64 °C. The average of WBGT index in 66.4% of units was up to 28°C. The average of relative humidity was 42.86%, the average of wet bulb temperature and globe temperature were 25.56°C and 36.72°C, respectively. The findings showed a significant correlation between the average of WBGT index and the standard recommendation level (p<0.0001. In dry cleaner units with less than 10 m2 area, heat stress was higher than other units  significantly (p<0.05. Conclusions: Heat stress in many dry cleaner units in Qom, Iran, was more than recommended OELs. Because of wet bulb and globe temperature in units were high value, the most important measures to heat controls, are technical engineering controls such as  radiation shield, insulation on boilers and modify the cooling systems.

    Using the recent INTEGRAL/IBIS and Swift/BAT surveys we have extracted a sample of radio galaxies selected in the soft gamma-ray band. The sample consists of known and candidate radio galaxies. The sample extraction criteria will be presented and its general properties outlined. In particular we provide strong evidence that this soft gamma-ray selection favours the discovery of large size radio objects, otherwise known as Giant Radio Galaxies or GRG. The main reasons and/or conditions leading to the formation of these sources are still unclear and this result suggests that they maybe related to exceptional internal properties of the source central engine, like a high jet power or a long activity time. Broad band analysis of new GRG, discovered during this work, will also be presented.

    To explore the relationship between autistic regression (AR) with and without EEG abnormalities and favourable outcome. Follow up data on children with favourable outcome in a series of 534 cases aged below 5 years and diagnosed as ASD. Cases with regression were 167 (31.8%), usually with persistent ASD, intellectual disabilities and EEG abnormalities. Thirty nine children (7.3%) went off autism and recovered entirely their intellectual and social abilities. Few of them included examples of pharmacologically treated Landau and Kleffner syndrome and other similar complex cases with abnormal EEG. The majority was represented by 36 (6.7%) children, mostly males, with a dysmaturational syndrome: their development was initially normal up to 18 months when an autistic regression occurred accompanied by the appearance of motor and vocal tics. Relational therapies were followed by rapid improvement. By 6 years all children had lost features of ASD and their I.Q. was in most cases between 90 and 110. Convulsions were absent and EEG was normal in all cases except one. In a few of them recovery was spontaneous. Seventeen children were followed after 5 years 6 months: 12 (70%) had ADHD, 10 (56%) persistent tics. Tics were often present in parents and relatives, ASD absent, suggesting a genetic background different from cases with persistent ASD. With one exception all "off autism" children had a previous autistic regression. In this series "off autism" children had either early onset epilepsy and/or EEG abnormalities or cases of dysmaturational syndrome. Autistic regression was present in almost all. Copyright © 2010.

    The objectives of this study were to identify factors associated with decisions concerning triage and admission to the intensive care unit and to describe the outcome of patients referred to intensive care unit for admission. The study was a single-centre, prospective, observational study. It was performed in the general intensive care unit of a tertiary regional hospital, over the period of February to June 2009. The patients were non-elective, acute medical in-patients. For 100 patients referred, only 36 were admitted to the intensive care unit. The remaining 64 were declined admission: nine were declined admission because they were assessed as too sick to benefit, 41 were declined admission because they were assessed as too well to benefit and 14 were deemed to potentially benefit from intensive care unit admission but were not admitted ('triage'). Patients most likely to receive triage decisions were medical in-patients who had expressed wishes about end-of-life care, who were functionally limited with co-morbid conditions affecting their performance status. Patients referred by Resident Medical Officers were also more likely to receive a triage decision. Age, gender Aboriginal and Torres Strait Islander status, diagnostic category and reason for referral did not impact on admission or triage decisions. Bed status in intensive care unit at the time of referral affected neither admission nor triage decisions. Hospital mortality in patients deemed too well to benefit from intensive care unit was 7.3%, suggesting that all patients referred for consideration of admission to intensive care unit should be classified as 'high risk'.

    Full Text Available Technical efficiency of hospital services is debated since performance has been heterogeneous. Staff time represents the main resource in patient care and its inappropriate allocation has been identified as a key factor of inefficiency. The aim of this study was to analyse the utilisation of physicians' work time stratified by staff groups, tasks and places of work. A further aim was to use these data to estimate resource use per unit of output.A self-reporting work-sampling study was carried during 14-days at a University Eye Hospital. Staff costs of physicians per unit of output were calculated at the wards, the operating rooms and the outpatient unit.Forty per cent of total work time was spent in contact with the patient. Thirty per cent was spent with documentation tasks. Time spent with documentation tasks declined monotonically with increasing seniority of staff. Unit costs were 56 € per patient day at the wards, 77 € and 20 € per intervention at the operating rooms for inpatients and outpatients, respectively, and 33 € per contact at the outpatient unit. Substantial differences in resources directly dedicated to the patient were found between these locations.The presented data provide unprecedented units costs in inpatient Ophthalmology. Future research should focus on analysing factors that influence differences in time allocation, such as types of patients, organisation of care processes and composition of staff.

  19. Future climate change will favour non-specialist mammals in the (sub)arctics.

    Arctic and subarctic (i.e., [sub]arctic) ecosystems are predicted to be particularly susceptible to climate change. The area of tundra is expected to decrease and temperate climates will extend further north, affecting species inhabiting northern environments. Consequently, species at high latitudes should be especially susceptible to climate change, likely experiencing significant range contractions. Contrary to these expectations, our modelling of species distributions suggests that predicted climate change up to 2080 will favour most mammals presently inhabiting (sub)arctic Europe. Assuming full dispersal ability, most species will benefit from climate change, except for a few cold-climate specialists. However, most resident species will contract their ranges if they are not able to track their climatic niches, but no species is predicted to go extinct. If climate would change far beyond current predictions, however, species might disappear. The reason for the relative stability of mammalian presence might be that arctic regions have experienced large climatic shifts in the past, filtering out sensitive and range-restricted taxa. We also provide evidence that for most (sub)arctic mammals it is not climate change per se that will threaten them, but possible constraints on their dispersal ability and changes in community composition. Such impacts of future changes in species communities should receive more attention in literature.

    B-cell prolymphocytic leukemia (B-PLL) comprises 1% of chronic lymphocytic leukemias. CD5 positivity is seen in 1/3rd of cases which generally arise from pre existing CLL. They have longer median survival compared with de novo B-PLL which are commonly CD5 negative and are more aggressive with an older age of presentation. Herewith, we describe a 48-year-old male of de-novo CD5+ B-PLL presenting with minimal lymphadenopathy and massive splenomegaly with 90% atypical lymphoid cells in the peripheral smear and bone marrow. Immunophenotyping was strongly positive for CD5, CD45, CD19, CD22, FMC-7, S-Ig and CD38, moderately positive for CD 11c, weakly positive for CD23 and negative for CD-103 and ZAP 70. The patient responded well to fludarabine and cyclophosphamide and had an uneventful hospital course. Our case illustrates a de-novo B-PLL with aberrant CD5 positivity who had a short duration of illness, younger age at presentation and favourable treatment outcome.

    Cryptic female choice may enable polyandrous females to avoid inbreeding or bias offspring variability at key loci after mating. However, the role of these genetic benefits in cryptic female choice remains poorly understood. Female red junglefowl, Gallus gallus, bias sperm use in favour of unrelated males. Here, we experimentally investigate whether this bias is driven by relatedness per se, or by similarity at the major histocompatibility complex (MHC), genes central to vertebrate acquired immunity, where polymorphism is critical to an individual's ability to combat pathogens. Through experimentally controlled natural matings, we confirm that selection against related males' sperm occurs within the female reproductive tract but demonstrate that this is more accurately predicted by MHC similarity: controlling for relatedness per se, more sperm reached the eggs when partners were MHC--dissimilar. Importantly, this effect appeared largely owing to similarity at a single MHC locus (class I minor). Further, the effect of MHC similarity was lost following artificial insemination, suggesting that male phenotypic cues might be required for females to select sperm differentially. These results indicate that postmating mechanisms that reduce inbreeding may do so as a consequence of more specific strategies of cryptic female choice promoting MHC diversity in offspring.

    Using the recent INTEGRAL/IBIS and Swift/BAT surveys we have extracted a sample of 64 confirmed plus 3 candidate radio galaxies selected in the soft gamma-ray band. The sample covers all optical classes and is dominated by objects showing a FR II radio morphology; a large fraction (70%) of the sample is made of radiative mode or High Excitation Radio Galaxies (HERG). We have measured the source size on NVSS, FIRST and SUMSS images and have compared our findings with data in the literature obtaining a good match. We surprisingly found that the soft gamma-ray selection favours the detection of large size radio galaxies: 60% of objects in the sample have size greater than 0.4 Mpc while around 22% reach dimension above 0.7 Mpc at which point they are classified as Giant Radio Galaxies or GRGs, the largest and most energetic single entities in the Universe. Their fraction among soft gamma ray selected radio galaxies is significantly larger than typically found in radio surveys, where only a few percent of objects ...

    Pro-inflammatory T cells mediate autoimmune demyelination in multiple sclerosis. However, the factors driving their development and multiple sclerosis susceptibility are incompletely understood. We investigated how micro-RNAs, newly described as post-transcriptional regulators of gene expression, contribute to pathogenic T-cell differentiation in multiple sclerosis. miR-128 and miR-27b were increased in naïve and miR-340 in memory CD4(+) T cells from patients with multiple sclerosis, inhibiting Th2 cell development and favouring pro-inflammatory Th1 responses. These effects were mediated by direct suppression of B lymphoma Mo-MLV insertion region 1 homolog (BMI1) and interleukin-4 (IL4) expression, resulting in decreased GATA3 levels, and a Th2 to Th1 cytokine shift. Gain-of-function experiments with these micro-RNAs enhanced the encephalitogenic potential of myelin-specific T cells in experimental autoimmune encephalomyelitis. In addition, treatment of multiple sclerosis patient T cells with oligonucleotide micro-RNA inhibitors led to the restoration of Th2 responses. These data illustrate the biological significance and therapeutic potential of these micro-RNAs in regulating T-cell phenotypes in multiple sclerosis.

    Different types of stressors trigger responses of different physiological systems, and these responses may contribute differentially to the maintenance of homeostasis, to trade-offs and the evolution of life-history traits. To manipulate two common stressors during reproduction, we infested half of the nests in a naturally breeding great tit population with ectoparasites and simultaneously manipulated brood size, using a 2×2 experimental design. Parents in this model species commonly compensate for ectoparasites by an increase in food provisioning. We assessed parental responses to these concurrent stressors by measuring several physiological stress parameters such as changes in metabolic rate, oxidative stress and expression of heat-shock proteins (Hsp), and explored how these stressors affect the trade-off between self-maintenance and reproduction. Neither flea infestation nor brood size manipulation affected adult metabolic rate, oxidative damage or Hsp levels. Furthermore, we found no interactive effect of the two treatments on adults. However, nestlings in infested nests had lower body mass and lower survival. Nestlings in enlarged broods were lighter and had lower survival, although parents of enlarged broods increased food provisioning rate. The findings suggest that adults favour maintenance of cellular homeostasis, and physiological equilibrium over current reproduction, and that the costs induced by both stressors, flea infestation and increased brood size, are carried by the offspring. It emphasizes the importance of self-maintenance over reproduction in life-history decisions, and more generally the need of including physiological traits for understanding the evolution of life-histories.

    There has been an ostensibly large number of extreme weather events in the Northern Hemisphere mid-latitudes during the past decade. An open question that is critically important for scientists and policy makers is whether any such increase in weather extremes is natural or anthropogenic in origin. One mechanism proposed to explain the increased frequency of extreme weather events is the amplification of mid-latitude atmospheric planetary waves. Disproportionately large warming in the northern polar regions compared with mid-latitudes--and associated weakening of the north-south temperature gradient--may favour larger amplitude planetary waves, although observational evidence for this remains inconclusive. A better understanding of the role of planetary waves in causing mid-latitude weather extremes is essential for assessing the potential environmental and socio-economic impacts of future planetary wave changes. Here we show that months of extreme weather over mid-latitudes are commonly accompanied by significantly amplified quasi-stationary mid-tropospheric planetary waves. Conversely, months of near-average weather over mid-latitudes are often accompanied by significantly attenuated waves. Depending on geographical region, certain types of extreme weather (for example, hot, cold, wet, dry) are more strongly related to wave amplitude changes than others. The findings suggest that amplification of quasi-stationary waves preferentially increases the probabilities of heat waves in western North America and central Asia, cold outbreaks in eastern North America, droughts in central North America, Europe and central Asia, and wet spells in western Asia.

    Over the past two decades the primary driver of mass loss from the West Antarctic Ice Sheet (WAIS) has been warm ocean water underneath coastal ice shelves, not a warmer atmosphere. Yet, surface melt occurs sporadically over low-lying areas of the WAIS and is not fully understood. Here we report on an episode of extensive and prolonged surface melting observed in the Ross Sea sector of the WAIS in January 2016. A comprehensive cloud and radiation experiment at the WAIS ice divide, downwind of the melt region, provided detailed insight into the physical processes at play during the event. The unusual extent and duration of the melting are linked to strong and sustained advection of warm marine air toward the area, likely favoured by the concurrent strong El Niño event. The increase in the number of extreme El Niño events projected for the twenty-first century could expose the WAIS to more frequent major melt events.

    Context. Dental unit waterlines may be heavily contaminated with microorganisms and are a potential source of infection for both practicing staff and immunocompromised patients particularly. Contamination of dental unit water lines could be inhibited with the use of disinfectants. The present study investigates the effect of aloe-vera-based disinfectant in reducing the microbial growth in dental unit water lines (DUWLs). Aims. To compare the efficacy of aloe vera, hydrogen peroxide (H2O2), and 5% sodium hypochlorite (NaOCl) in controlling microbial contamination of DUWLs. Materials and Methods. After obtaining baseline water samples, the dental unit waterlines were treated with aloe vera, 10% hydrogen peroxide, and 5% sodium hypochlorite. Each of the three disinfectants was used in increasing concentrations and their inhibiting effect was compared. Water samples were analyzed for microbiological quality by the total viable count (TVC) method. Statistical Analysis Used. SPSS 16. Results. There was significant reduction in mean CFU/ml when treated with disinfectants each for a period of one week. Aloe-vera solution was found to be the most effective in reducing the microbial colonies. Conclusions. Improving the water quality from dental unit water lines is of considerable importance; chemical-based disinfectants can be replaced with herbal disinfectants for treating microbial contamination in dental unit waterlines.

  1. Relax and refill: xylem rehydration prior to hydraulic measurements favours embolism repair in stems and generates artificially low PLC values.

    2014-11-01

    Diurnal changes in percentage loss of hydraulic conductivity (PLC), with recorded values being higher at midday than on the following morning, have been interpreted as evidence for the occurrence of cycles of xylem conduits' embolism and repair. Recent reports have suggested that diurnal PLC changes might arise as a consequence of an experimental artefact, that is, air entry into xylem conduits upon cutting stems, even if under water, while under substantial tension generated by transpiration. Rehydration procedures prior to hydraulic measurements have been recommended to avoid this artefact. In the present study, we show that xylem rehydration prior to hydraulic measurements might favour xylem refilling and embolism repair, thus leading to PLC values erroneously lower than those actually experienced by transpiring plants. When xylem tension relaxation procedures were performed on stems where refilling mechanisms had been previously inhibited by mechanical (girdling) or chemical (orthovanadate) treatment, PLC values measured in stems cut under native tension were the same as those measured after sample rehydration/relaxation. Our data call for renewed attention to the procedures of sample collection in the field and transport to the laboratory, and suggest that girdling might be a recommendable treatment prior to sample collection for PLC measurements.

    The aim of this study was to determine the relative effects of landscape-scale management intensity, local management intensity and edge effect on diversity patterns of insect-pollinated vs. non-insect pollinated forbs in meadows and wheat fields. Nine landscapes were selected differing in percent intensively used agricultural area (IAA), each with a pair of organic and conventional winter wheat fields and a pair of organic and conventional meadows. Within fields, forbs were surveyed at the edge and in the interior. Both diversity and cover of forbs were positively affected by organic management in meadows and wheat fields. This effect, however, differed significantly between pollination types for species richness in both agroecosystem types (i.e. wheat fields and meadows) and for cover in meadows. Thus, we show for the first time in a comprehensive analysis that insect-pollinated plants benefit more from organic management than non-insect pollinated plants regardless of agroecosystem type and landscape complexity. These benefits were more pronounced in meadows than wheat fields. Finally, the community composition of insect-pollinated and non-insect-pollinated forbs differed considerably between management types. In summary, our findings in both agroecosystem types indicate that organic management generally supports a higher species richness and cover of insect-pollinated plants, which is likely to be favourable for the density and diversity of bees and other pollinators.

  3. The evolution of colour pattern complexity: selection for conspicuousness favours contrasting within-body colour combinations in lizards.

    Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and short-wavelength colour patches are located on the ventral and lateral surfaces of many lacertid lizards. As the combination of long- and short-wavelength-based colours generates local chromatic contrast, we hypothesized that selection may favour the co-occurrence of lateral and ventral contrasting patches, resulting in complex colour patterns that maximize the overall conspicuousness of the signal. To test this hypothesis, we performed a comparative phylogenetic study using a categorical colour classification based on spectral data and descriptive information on lacertid coloration collected from the literature. Our results demonstrate that conspicuous ventral (long-wavelength-based) and lateral (short-wavelength-based) colour patches co-occur throughout the lacertid phylogeny more often than expected by chance, especially in the subfamily Lacertini. These results suggest that selection promotes the evolution of the complex pattern rather than the acquisition of a single conspicuous colour patch, possibly due to the increased conspicuousness caused by the combination of colours with contrasting spectral properties.

    Organometallic complexes possess great potential for imaging applications in biology, due to their kinetic stability and often favourable intrinsic properties. In this work we present a new class of Re(I) -tricarbonyl complexes with a substituted bis(phenanthridinylmethyl)amine (bpm) ligand. The complex Re(CO)(3) (R-bpm) could be conveniently prepared by microwave synthesis from [Re(CO)(3)(H(2)O)(3) ]Br and a suitably substituted bis(phenanthridinylmethyl)amine (R-bpm). Complex 5, with R=CH(2)-CO(2)-CH(3) , was characterized by a single-crystal X-ray structure. Complex 6 (R=CH(2)-C(6)H(4)-CO(2)H) was used in solid-phase peptide synthesis (SPPS) to label the neurotensin(8-13) (NT) fragment N-terminally. The complexes show luminescence emission with large Stokes shifts (λ(ex) =350 nm, λ(em) =570 nm). Cellular uptake and intracellular localization studies in several cell lines demonstrate the utility of the new Re(CO)(3) (R-bpm) complexes for fluorescence imaging and reveal significant differences between the simple methyl ester 5 and the NT bioconjugate 7.

    Full Text Available Background: Nosocomial infections are an important cause of mortality in neonatal intensive care units (NICUs. Therefore, in this study, the incidence and prevalence of nosocomial infections were determined in NICUs of the three largest neonatal centers in northwest Iran, and the causative bacteria were identified in order to provide potential solutions to control the infections in these hospitals. Materials and Methods: This is a descriptive-prospective study in which the cases of nosocomial infections were examined in the three largest hospitals in Tabriz in northwest Iran during 1 year (from June 2012 until May 2013 based on clinical findings, medical and nursing reports of patients, and laboratory results. Results: Of the 3129 patients hospitalized in NICUs of the three hospitals, 208 patients were diagnosed with nosocomial infections. The incidence rate of nosocomial infections was 11.34%.per 100 patient days with 52.4% bacteremia, 32.69% pneumonia, 5.77% urinary tract infections, 5.29% wound infections, and 3.85% necrotizing enterocolitis. There was a statistically significant relationship between invasive procedures (such as umbilical catheters, central venous catheters, surgery, and TPN and sepsis (P = 0.001. The relationships between urinary tract infection and urinary catheter (P = 0.000, and aggressive procedures (such as suctioning and intubation and pneumonia (P = 0.001 were also statistically significant. Conclusion: Incidence of nosocomial infections in premature and low birth weight newborns is considered as a health threat. The findings of this research reiterate the importance of giving further attention to prevention and control of nosocomial infections in the NICU.

    Statistical downscaling is used to improve the knowledge of spatial distributions from broad–scale to fine–scale maps with higher potential for conservation planning. We assessed the effectiveness of downscaling in two commonly used species distribution models: Maximum Entropy (MaxEnt) and the Favourability Function (FF). We used atlas data (10 x 10 km) of the fire salamander Salamandra salamandra distribution in southern Spain to derive models at a 1 x 1 km resolution. Downscaled models were assessed using an independent dataset of the species’ distribution at 1 x 1 km. The Favourability model showed better downscaling performance than the MaxEnt model, and the models that were based on linear combinations of environmental variables performed better than models allowing higher flexibility. The Favourability model minimized model overfitting compared to the MaxEnt model. (Author)

  7. Favourable areas for expansion and reintroduction of Iberian lynx accounting for distribution trends and genetic variation of the wild rabbit

    2010-12-01

    Full Text Available Although on a local scale Iberian lynx distribution is determined by the availability of prey rabbits, recent modelling analyses have uncovered broad-scale disagreements between these two species’ distribution trends. These analyses showed also that the lynx had become restricted to only a fraction of the rabbit’s genetic variability, and that this could be jeopardising its survival in the face of environmental hazards and uncertainty. In the present paper, a follow-up was carried out through the building of lynx and rabbit distribution models based on the most recent Spanish mammal atlas. The predictions of environmental favourability (which is an indicator of abundance for lynx and rabbit were positively correlated within the lynx's current distribution area, but they were negatively correlated within the total Spanish area where lynx occurred in the 1980’s. Environmental favourability for rabbits was significantly higher where lynx maintains reproductive populations than where it recently disappeared, indicating that rabbit favourability plays an important role and can be a good predictor of lynx persistence. The lynx and rabbit models were extrapolated to predict favourable areas for both species in Spain as well as in Portugal, on the original scale of the distribution data (10x10 km and on a 100 times finer spatial resolution (1x1 km. The lynx and rabbit models were also combined through fuzzy logic to forecast the potential for lynx occurrence incorporating information on favourable areas for its main prey. Several areas are proposed as favourable for lynx expansion or re-introduction, encompassing both countries and both genetic lineages of the rabbit.

    Background Childhood growth affects long-term health and could contribute to health inequalities that persist throughout life. Methods We compared growth data of 4-6 year old children born 1997-2002 in UK (n=15,168), Sweden (n=6,749) and rural China (n=10,327). Standard deviation scores (SDS) were calculated against the WHO Standard. Obesity and overweight were defined by International Obesity Taskforce cut-offs, and stunting, underweight and thinness by height, weight or BMI < −2 SDS. Associations with maternal education were standardised by calculating the Slope Index of Inequality (SII). Results Mean SDS height, weight and BMI in UK (−0.01; 0.42; 0.62, respectively) and Sweden (0.45; 0.59; 0.45) were higher than in China (−0.98, −0.82, −0.29). Higher maternal education was consistently associated with taller offspring height SDS (SII: UK 0.25; Sweden 0.17; China 1.06). Underweight and stunting were less common in UK (prevalence: 0.6% and 2.2%, respectively) and Sweden (0.3% and 0.6%) than in China (9.5% and 16.4%), where these outcomes were inversely associated with maternal education (SII: −25.8% and −12.7%). Obesity prevalence in UK, Sweden and China was 4.8%, 3.7% and 0.4%, respectively. Maternal education was inversely associated with offspring obesity in UK (SII: −3.3%) and Sweden (−2.8%), but not in China (+0.3%). Conclusions Higher maternal education was associated with more favourable growth in young children: lower obesity and overweight in UK and Sweden, and lower stunting and underweight in rural China. Public health strategies to optimize growth in early childhood need to acknowledge socioeconomic factors, but possibly with a different emphasis in different settings. PMID:23450064

    We provide the analysis of the spatial and temporal distribution of ultraviolet (UV) radiation over Northern Eurasia taking into account for both its detrimental (erythema and eye-damage effects) and favourable (vitamin D synthesis) influence on human health. The UV effects on six different skin types are considered in order to cover the variety of skin types of European and Asian inhabitants. To better quantifying the vitamin D irradiance threshold we accounted for an open body fraction S as a function of effective air temperature. The spatial and temporal distribution of UV resources was estimated by radiative transfer (RT) modeling (8 stream DISORT RT code) with 1x 1 degree grid and monthly resolution. For this purpose special datasets of main input geophysical parameters (total ozone content, aerosol characteristics, surface UV albedo, UV cloud modification factor) have been created over the territory of Northern Eurasia, which can be of separate interest for the different multidisciplinary scientific applications over the PEEX domain. The new approaches were used to retrieve aerosol and cloud transmittance from different satellite and re-analysis datasets for calculating the solar UV irradiance at ground. Using model simulations and some experimental data we provide the altitude parameterization for different types of biologically active irradiance in mountainous area taking into account not only for the effects of molecular scattering but for the altitude dependence of aerosol parameters and surface albedo. Based on the new classification of UV resources (Chubarova, Zhdanova, 2013) we show that the distribution of harmful (UV deficiency and UV excess) and favorable UV conditions is regulated by various geophysical parameters (mainly, total ozone, cloudiness and open body fraction) and can significantly deviate from latitudinal dependence. The interactive tool for providing simulations of biologically active irradiance and its attribution to the different

    Awareness with recall after general anesthesia is an infrequent, but well described, phenomenon that may result in posttraumatic stress disorder. There are no recent data on the incidence of this complication in the United States. We, therefore, undertook a prospective study to determine the incidence of awareness with recall during general anesthesia in the United States. This is a prospective, nonrandomized descriptive cohort study that was conducted at seven academic medical centers in the United States. Patients scheduled for surgery under general anesthesia were interviewed in the postoperative recovery room and at least a week after anesthesia and surgery by using a structured interview. Data from 19,575 patients are presented. A total of 25 awareness cases were identified (0.13% incidence). These occurred at a rate of 1-2 cases per 1000 patients at each site. Awareness was associated with increased ASA physical status (odds ratio, 2.41; 95% confidence interval, 1.04-5.60 for ASA status III-V compared with ASA status I-II). Age and sex did not influence the incidence of awareness. There were 46 additional cases (0.24%) of possible awareness and 1183 cases (6.04%) of possible intraoperative dreaming. The incidence of awareness during general anesthesia with recall in the United States is comparable to that described in other countries. Assuming that approximately 20 million anesthetics are administered in the United States annually, we can expect approximately 26,000 cases to occur each year.

    We determined the results of shock wave lithotripsy with a newer electromagnetic lithotriptor and compared them with those in a contemporary series of cases managed by an electrohydraulic lithotriptor using identical treatment and followup criteria at a single center. Between 1995 and 1999, 356 patients (375 renal units, 483 upper urinary tract stones) meeting study inclusion criteria were treated with an MFL 5000 electrohydraulic shock wave lithotripsy unit (Dornier Medical Systems, Inc., Marietta, Georgia). From 1999 to 2000, 173 patients (175 renal units; 218 upper urinary tract stones) meeting identical study inclusion criteria were treated using an electromagnetic Modulith SLX shock wave lithotripsy unit (Karl Storz Lithotripsy, Atlanta, Georgia). In each group stone-free results were determined by plain abdominal x-ray and renal ultrasound 1 month after lithotripsy and efficiency quotients were developed. Baseline patient and stone characteristics were compared by the Wilcoxon rank sum and Fisher exact tests. All variables significant at p electromagnetic lithotripsy units (0.45 and 0.42, respectively, p = 0.43). Electrohydraulic lithotripsy resulted in a higher stone-free rate at 1 month, although it was associated with a higher rate of auxiliary measures. Ultimately the efficiency quotients were equivalent, implying that these 2 contemporary energy sources are acceptable. According to single center treatment and followup criteria they are equally efficacious.

    In pre-war years, the main stream of Japanese psychiatry belonged to the German School, and many eminent psychiatrists studied in Germany. As far as I could confirm, eleven Japanese psychiatrists studied in the United States in pre-war years. The first one was Saburo Matsubara (1877-1936), who studied under Adolf Meyer during the years 1903-1908. Nine psychiatrists studied in the United States during the years of World War I or just after it. Five of them studied under Meyer, and four others at the Wistar Institute of Biology and Anatomy. The last one, Tsuneo Muramatsu (1900-1981), studied at Harvard University during the years 1933-1935. In pre-war years, the seeds sown by them opened into very small flowers. But in post-war years, the seeds bore good fruit in the form of the introduction of dynamic concepts into Japanese psychiatry.

    Full Text Available Abstract Global research has shown the persistence of inequality with regard to accessing curriculum with a view to obtaining suitable work and making useful contributions to society. The intersection of race, gender, language and low socio-economic levels creates situations which often marginalize ethnic minorities in school settings (Freire, 1968; Nieto & Turner, 2012. The graduation rates in the United States for Native American, African American and Hispanic students are lower than the graduation rates of Whites and Asian Americans. In addition, Bangladeshis and African Caribbeans currently living in the UK are under-represented in higher education, particularly young men in those communities. The research questions that guide this inquiry are: (1 According to databases, how does the academic performance of language minority groups compare to the academic performance of non-linguistic minority groups at the elementary and secondary levels of education? (2 According to language support teachers and university students, what are the strengths and weaknesses of the instructional practices for language minorities who are learning English in the United Kingdom (UK (Bristol and the United States (US (Henrico? Participants were: five UK teachers, four UK university students, five US teachers, four US university students. Data collection supervised by lead researchers included interviews, focus groups, classroom observation, and performance documents. Data analysis utilized a mixed-methods approach. Overall, linguistic minority groups performed lower than their English proficient peers. Culturally, UK teachers provided a greater emphasis on religious instruction, whereas US teachers addressed patriotic topics more frequently. Teachers in the United States and the United Kingdom were culturally supportive with slight variation in the encouraged use of the students’ heritage languages.

  17. Digital mapping of soil related common European biophysical criteria used for the identification of Less Favoured Areas in Hungary

    One of the main objectives of the EU's Common Agricultural Policy is to encourage maintaining agricultural production in less favoured areas (LFA) in order to sustain agricultural production and use natural resources, in such a way to secure both stable production and income to farmers and to protect the environment. LFA assignment has both ecological and severe economical aspects. Recently the delimitation of LFAs is suggested to be carried out by using common biophysical diagnostic criteria on low soil productivity and poor climate conditions all over Europe. The criterion system was elaborated by JRC and its operational implementation comes under member state competence. This process requires the existence of an adequate national spatial soil information system with appropriate data structure and spatial resolution as well as a proper methodology for its analysis. Hungary possesses an appropriate nationwide, 1:25,000 scale legacy data set originating from the national soil mapping project, which was initiated and led by Kreybig. This national survey was based on field and laboratory soil analyses and at the same time serving practical purposes. Its objective was the preparation of a map series which gives an insight to the geographical site and extent of soil conditions and soil properties for the production directing authorities, agricultural policy-makers, farmers, and the research institutes related to production problems. The similarity between the objectives of the old national mapping and those of the present European activities is remarkable. In the fifties, when the survey was completed, Hungary was the first in the world to have 1:25,000 scale soil information for the whole country. Overall chemical and physical soil properties of the soil root zone featuring soil patches were identified for croplands. Three characteristics were attributed to soil mapping units and displayed on the maps; further soil properties were determined and measured in soil

  7. The units of measurement of the ventricular stroke work: a review study.

    Science.gov (United States)

    Schramm, Wolfgang

    2010-06-01

    The ventricular stroke work refers to the work done by the left or right ventricle to eject the volume of blood during one cardiac cycle, called stroke volume. Sarnoff and Berglund were one of the first to calculate the stroke work from the pressure volume diagram in 1954. However, they published a wrong unit of measurement for the stroke work, namely gram meter. The present work reviewed 779 scientific publications between May 1954 and January 2010 which used the left or right ventricular stroke work as a variable. Interestingly, the majority (87.2%) of scientific papers since 1954 have either copied this (or a similar) wrong unit of measurement or have invented another one. Only 12.8% of the publications gave a correct unit. The present search in scientific literature demonstrates that the haemodynamic variable ventricular stroke work, which is used daily by thousands of medical doctors and scientists, was specified in an incorrect manner for 56 years in the majority of scientific papers. A correct unit of measurement, of course, is an imperative condition when comparing scientific papers. The aim of this publication is the elimination of incorrect units of measurement of the ventricular stroke work variable in all future scientific papers. Moreover, the present work facilitates the interpretation of at least some of the studies containing the ventricular stroke work variable published up to now.

  11. Heterosis may result in selection favouring the products of long-distance pollen dispersal in Eucalyptus.

    Directory of Open Access Journals (Sweden)

    João Costa E Silva

    Full Text Available Using native trees from near the northern and southern extremities of the relatively continuous eastern distribution of Eucalyptus globulus in Tasmania, we compared the progenies derived from natural open-pollination (OP with those generated from within-region and long-distance outcrossing. Controlled outcrossing amongst eight parents - with four parents from each of the northern and southern regions - was undertaken using a diallel mating scheme. The progeny were planted in two field trials located within the species native range in southern Tasmania, and their survival and diameter growth were monitored over a 13-year-period. The survival and growth performances of all controlled cross types exceeded those of the OP progenies, consistent with inbreeding depression due to a combination of selfing and bi-parental inbreeding. The poorer survival of the northern regional (♀N♂N outcrosses compared with the local southern regional outcrosses (♀S♂S indicated differential selection against the former. Despite this mal-adaptation of the non-local ♀N♂N crosses at both southern sites, the survival of the inter-regional hybrids (♀N♂S and ♀S♂N was never significantly different from that of the local ♀S♂S crosses. Significant site-dependent heterosis was detected for the growth of the surviving long-distance hybrids. This was expressed as mid-parent heterosis, particularly at the more northern planting site. Heterosis increased with age, while the difference between the regional ♀N♂N and ♀S♂S crosses remained insignificant at any age at either site. Nevertheless, the results for growth suggest that the fitness of individuals derived from long-distance crossing may be better at the more northern of the planting sites. Our results demonstrate the potential for early-age assessments of pollen dispersal to underestimate realised gene flow, with local inbreeding under natural open-pollination resulting in selection favouring the

  12. The effects of defoliation on carbon allocation: can carbon limitation reduce growth in favour of storage?

    Wiley, Erin; Huepenbecker, Sarah; Casper, Brenda B; Helliker, Brent R

    2013-11-01

    There is no consensus about how stresses such as low water availability and temperature limit tree growth. Sink limitation to growth and survival is often inferred if a given stress does not cause non-structural carbohydrate (NSC) concentrations or levels to decline along with growth. However, trees may actively maintain or increase NSC levels under moderate carbon stress, making the pattern of reduced growth and increased NSCs compatible with carbon limitation. To test this possibility, we used full and half defoliation to impose severe and moderate carbon limitation on 2-year-old Quercus velutina Lam. saplings grown in a common garden. Saplings were harvested at either 3 weeks or 4 months after treatments were applied, representing short- and longer-term effects on woody growth and NSC levels. Both defoliation treatments maintained a lower total leaf area than controls throughout the experiment with no evidence of photosynthetic up-regulation, and resulted in a similar total biomass reduction. While fully defoliated saplings had lower starch levels than controls in the short term, half defoliated saplings maintained control starch levels in both the short and longer term. In the longer term, fully defoliated saplings had the greatest starch concentration increment, allowing them to recover to near-control starch levels. Furthermore, between the two harvest dates, fully and half defoliated saplings allocated a greater proportion of new biomass to starch than did controls. The maintenance of control starch levels in half defoliated saplings indicates that these trees actively store a substantial amount of carbon before growth is carbon saturated. In addition, the allocation shift favouring storage in defoliated saplings is consistent with the hypothesis that, as an adaptation to increasing carbon stress, trees can prioritize carbon reserve formation at the expense of growth. Our results suggest that as carbon limitation increases, reduced growth is not necessarily

    Full Text Available Small industrial units are the seedbed on industrial development in underdeveloped economy for its less capital involvement and more employment generation capability. But this sector cannot contribute expectedly for infection to sickness that ultimately prevents the entrepreneurial bases of economy. Sickness can be occurred in the inception period, in operation and /or in macro environment.There are various techniques to prevent sickness and to make the treatment of occurred sickness. In this study, the researchers selected 13 sick units of BSCIC industrial units and collected the information regarding the causes, stages and measures to prevent sickness. It is found that 07 are born to sick due to improper capital budgeting, 06 are made sick for managerial problems and no units are bound to be sick for environmental problems.

  14. Are freestanding midwifery units a safe alternative to obstetric units for low-risk, primiparous childbirth? An analysis of effect differences by parity in a matched cohort study.

    Christensen, Louise Fischer; Overgaard, Charlotte

    2017-01-09

    Intrapartum complications and the use of obstetric interventions are more common in primiparous childbirth than in multiparous childbirth, leading to concern about out of hospital birth for primiparous women. The purpose of this study was to determine whether the effect of birthplace on perinatal and maternal morbidity and the use of obstetric interventions differed by parity among low-risk women intending to give birth in a freestanding midwifery unit or in an obstetric unit in the North Denmark Region. The study is a secondary analysis of data from a matched cohort study including 839 low-risk women intending birth in a freestanding midwifery unit (primary participants) and 839 low-risk women intending birth in an obstetric unit (individually matched control group). Analysis was by intention-to-treat. Conditional logistic regression analysis was applied to compute odds ratios and effect ratios with 95% confidence intervals for matched pairs stratified by parity. On no outcome did the effect of birthplace differ significantly between primiparous and multiparous women. Compared with their counterparts intending birth in an obstetric unit, both primiparous and multiparous women intending birth in a freestanding midwifery unit were significantly more likely to have an uncomplicated, spontaneous birth with good outcomes for mother and infant and less likely to require caesarean section, instrumental delivery, augmented labour or epidural analgesia (although for caesarean section this trend did not attain statistical significance for multiparous women). Perinatal outcomes were comparable between the two birth settings irrespective of parity. Compared to multiparas, transfer rates were substantially higher for primiparas, but fell over time while rates for multiparas remained stable. Freestanding midwifery units appear to confer significant advantages over obstetric units to both primiparous and multiparous mothers, while their infants are equally safe in both settings

    Since 1992 agri-environmental issues have gained attention by reforms of the CAP. For instance by supporting environmentally friendly land use, such as permanent pastures in less-favoured areas (LFA) that are only marginally suitable for alternative farming practices. In the last two decades a si

  17. Putative IL-10 Low Producer Genotypes Are Associated with a Favourable Etanercept Response in Patients with Rheumatoid Arthritis.

    Full Text Available Outcome predictors of biologic therapeutic drugs like TNF inhibitors are of interest since side effects like serious infections or malignancy cannot be completely ruled out. Response rates are heterogeneous. The present study addressed the question whether in patients with rheumatoid arthritis (RA interleukin-10 (IL-10 promoter genotypes with potential relevance for IL-10 production capacity are associated with response to long-term treatment with etanercept. Caucasian RA patients that, according to the EULAR criteria, responded well (n = 25, moderately (n = 17 or not (n = 8 to etanercept therapy (median 36 months, range 4-52, and 160 matched controls were genotyped for the IL-10 promoter SNPs -2849 G>A (rs6703630, -1082 G>A (rs1800896, -819 C>T (rs1800871 and -592 C>A (rs1800872. Haplotypes were reconstructed via mathematic model and tested for associations with disease susceptibility and therapy response. We identified the four predominant haplotypes AGCC, GATA, GGCC, and GACC in almost equal distribution. Patients that responded well carried the putative IL-10 low producer allele -2849 A or the haplotypes AGCC and GATA (RR 2.1 and 4.0, respectively; 95% CI 1.1-4.0 and 1.1-14.8, whereas an unfavourable response was associated with carriage of the putative high producer haplotype GGCC (RR 1.9, 95% CI 1.1-3.3. No significant associations of alleles or haplotypes with disease susceptibility were observed. In RA, a low IL-10 production which is genetically determined rather by haplotypes than by SNPs may favour the response to etanercept treatment. Iatrogenic blockade of TNF may reveal proinflammatory effects of its endogeneous antagonist IL-10. Further studies are needed to correlate these genetic findings to direct cytokine measurements.

    Full Text Available Introduction & aim: With respect to the outbreak probability of dangerous infections among the patients, the water sources of dentistry units were taken into consideration, in view of microbial contamination. The objective of this study was to assess of pathogenic organisms of the water used in the dentistry units of Yasuj city. Methods: In this research 120 samples of water from poir and turbine of units (before and after flushing and two samples of urban water were collected. Sampling was performed on the first weekday (48 hours after the units were switched off and mid week(16 hours after the units were switched off before starting work. The samples were cultured on EMB Agar and Blood Agar and incubated at 37oC for purification for Gram positive or Gram negative bacteria and it was identifying with biochemical diagnostic test .Also the samples were counted by standard plate count . Results: The average count of bacteria before flushing in Poir on the first weekday was 5360CFU/L and turbine was 2800 CFU/L and count of bacteria after flushing in Poir on the first weekday was 1040 CFU/L and turbine was 1020 CFU/L .While this result for midweek day : The average count of bacteria before flushing in Poir was 3220 CFU/L and turbine was 2720CFU/L and count of bacteria after flushing in Poir was 1772 CFU/L and turbine was 980 CFU/L . Several samples of before and after flushing were contaminated with E.coli, Pseudomonas ,Proteus, Kelebsiella ,gram positive bacilli ,Streptococci, Staphylococci , Diplo cocci and Yeast. Conclusion: According to the result of this study the contamination rate of the unit’s water was high and it’s rate reduced after flushing. The patients saliva causes water unit contamination and it constitutes biofilm in pipe of unit . Existence of E.coli shows the contamination of water to sewage and staphylococcus explains contamination due to return of the patient’s saliva into suctions. dental units waterlines showed bacterial

    Criticism of the "war on drugs" pursued under Republican administrations has grown in the United States. With the election of Bill Clinton many experts expected a shift from law enforcement policies to an approach favouring treatment and prevention. The budget announced in April, however, revealed no such shift in allocation of resources. Although the war on drugs has apparently failed to reduce the supply of cheap heroin and cocaine to the United States, the prevention strategy favoured by i...

    1994-01-01

    This feasibility study (FS) examines a range of alternatives and provides recommendations for selecting a preferred altemative for remediating contamination at the 200-BP-1 operable unit. The 200-BP-1 operable unit is located in the center of the Hanford Site along the northern boundary of the 200 East Area. The 241-BY Tank Farm is located immediately to the south of the operable unit. 200-BP-1 is a source operable unit with contaminated soils associated primarily with nine inactive cribs (known as the 216-B cribs). These cribs were used for disposal of low-level radioactive liquid waste from U Plant uranium recovery operations, and waste storage tank condensate from the adjacent 241-BY Tank Farm. The cribs used for disposal of U Plant waste were in operation from 1955--1965, and the cribs used for disposal of tank condensate were in operation from 1965-1975. In addition to the cribs, four unplanned releases of radioactive materials have occurred within the operable unit. Contaminated surface soils associated with the unplanned releases have been consolidated over the cribs and covered with clean soil to reduce contaminant migration and exposure. Discharge of wastes to the cribs has resulted in soil and groundwater contamination. The groundwater is being addressed as part of the 200 East Aggregate Area groundwater operable unit. Contaminated soils at the site can be categorized by the types of contaminants, their distribution in the soil column, and the risk posed by the various potential exposure pathways. Below the clean soil cover, the near surface soils contain low-:levels of contamination with cesium-137, radium-226, strontium-90, thorium-228 and uranium. The lifetime incremental cancer risk associated with these soils if they were exposed at the surface is 9 {times} 10{sup 5}.

    To explore the quality of interprofessional teamwork in acute geriatric care and to build a model of team types. Cross-sectional multicenter study. Acute geriatric units in Belgium. Team members of different professional backgrounds. Perceptions of interprofessional teamwork among team members of 55 acute geriatric units in Belgium were measured using a survey covering collaborative practice and experience, managerial coaching and open team culture, shared reflection and decision-making, patient files facilitating teamwork, members' belief in the power of teamwork, and members' comfort in reporting incidents. Cluster analysis was used to determine types of interprofessional teamwork. Professions and clusters were compared using analysis of variance. The overall response rate was 60%. Of the 890 respondents, 71% were nursing professionals, 20% other allied health professionals, 5% physicians, and 4% logistic and administrative staff. More than 70% of respondents scored highly on interprofessional teamwork competencies, consultation, experiences, meetings, management, and results. Fewer than 55% scored highly on items about shared reflection and decision-making, reporting incidents from a colleague, and patient files facilitating interprofessional teamwork. Nurses in this study rated shared reflection and decision-making lower than physicians on the same acute geriatric units (P teamwork in acute geriatric units is satisfactory, but shared reflection and decision-making needs improvement. Four types of interprofessional teamwork are identified and can be used to benchmark the teamwork of individual teams. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental conditions above the threshold for a positive carbon balance, benefitting evergreen woody species more than deciduous ones. The comparatively lower solar energy input in winter decreases the foliar light saturation point. This leads to a higher susceptibility to photoinhibitory stress especially when chilly (change persisted for several weeks after the cold period despite the recovery of the temperature to the conditions previous to the frost event. The responses of Vc, max and Jmax were highly species-specific, where Q. ilex exhibited the highest and P. halepensis the lowest reductions. In contrast, the optimal fluorometric quantum yield of photosystem II (Fv/Fm) was significantly lower in A. unedo after the cold period. The leaf position played an important role in Q. ilex showing a comparatively stronger winter effect on sunlit leaves. Our results generally agreed with the previous classifications of photoinhibition-avoiding (P. halepensis) and photoinhibition-tolerant (Q. ilex) species on the basis of their susceptibility to dynamic photoinhibition, whereas A. unedo was the least tolerant to photoinhibition, which was chronic in this species. Q. ilex and P. halepensis seem to follow contrasting photoprotective strategies which are, however, equally successful under the prevailing conditions exhibiting an adaptive advantage over A. unedo in our study site. These results show that our understanding of the dynamics of interspecific competition in Mediterranean ecosystems requires consideration of the physiological behaviour during winter which may have important implications for long-term carbon budgets and growth trends.

    Given that the communities which are most vulnerable to HIV often have little control over their own lives and their health-related behaviour, HIV prevention policies increasingly recommend that HIV prevention projects work to build relationships with powerful external groups (i.e., build "bridging social capital"). To aid conceptualisation of how community organisations may build such social capital, this paper outlines a typology of strategies for influencing local stakeholders. We present a study of two successful Indian sex workers' organisations, VAMP and DMSC, focusing on how the organisations have influenced three groups of stakeholders, namely police, politicians and local social organisations. Interviews with project employees (45), with representatives of the three groups of stakeholders (12) and fieldwork diaries recording 6 months of observation in each site provide the data. Three approaches emerged. "Persuading" refers to the practice of holding information-giving meetings with stakeholders and requesting their support. It appears to build "weak social ties". "Protesting" entails a collective confrontation with stakeholders, and appears to be useful when the stakeholder has a public image to protect that would be tarnished by protest, and when the protestors can stake a legitimate claim that their rights are being denied. In "exchanging favours", the sex workers' organisations find creative ways to position themselves as offering valued resources to their stakeholders (such as useful information on criminal activities for the police, a stage and audience for politicians or a celebration for local social organisations) as incentives for their support. In conclusion, we discuss the strengths and weaknesses of each approach, the implications for social capital theorising and implications for community HIV prevention.

    During this time, mathematics is considered as something neutral and not associated with culture. It can be seen from mathematics learning in the school which adopt many of foreign mathematics learning are considered more advanced (western). In fact, Indonesia is a rich country in cultural diversity. In the cultural activities, there are mathematical ideas that were considered a important thing in the mathematics learning. A study that examines the idea or mathematical practices in a variety of cultural activities are known as ethnomathematics. In Indonesia, there are some ethnic maintain their ancestral traditions, one of them is Kampung Naga. Therefore, this study was conducted in Kampung Naga. This study aims to uncover units of length, area, and volume used by Kampung Naga society. This study used a qualitative approach and ethnography methods. In this research, data collection is done through the principles of ethnography such as observation, interviews, documentation, and field notes. The results of this study are units of length, area, and volume used by Kampung Naga society and its conversion into standard units. This research is expected to give information to the public that mathematics has a relationship with culture and become recommendation to mathematics curriculum in Indonesia.

    This is the Chinese translation of NREL/TP-6A20-67613. This report expands on a previous National Renewable Energy Laboratory (NREL) technical report (Lowder et al. 2015) that focused on the United States' unique approach to distributed generation photovoltaics (DGPV) support policies and business models. While the focus of that report was largely historical (i.e., detailing the policies and market developments that led to the growth of DGPV in the United States), this report looks forward, narrating recent changes to laws and regulations as well as the ongoing dialogues over how to incorporate distributed generation (DG) resources onto the electric grid. This report also broadens the scope of Lowder et al. (2015) to include additional countries and technologies. DGPV and storage are the principal technologies under consideration (owing to market readiness and deployment volumes), but the report also contemplates any generation resource that is (1) on the customer side of the meter, (2) used to, at least partly, offset a host's energy consumption, and/or (3) potentially available to provide grid support (e.g., through peak shaving and load shifting, ancillary services, and other means).

    Full Text Available Destructive eye surgery is associated with more complications than just loss of visual functions of the eye and aesthetics. Currently there is very little published literature on post-destructive eye surgery associated depression. Zimbabwe has been experiencing a surge in the rate of destructive eye surgery done at the National Tertiary Eye Unit. This situation could be churning out lots of unrecognized depressed clients into the community who require assistance in one form or another.Objectives: To determine the prevalence of post-destructive eye surgery associated depression among patients attending Sekuru Kaguvi Hospital Eye Unit and assess if the current management protocol of patients undergoing destructive eye surgery at the Eye Unit addresses the problem adequately.Methods: A cross-sectional study of 28 randomly selected patients who had destructive eye surgeries at Sekuru Kaguvi Hospital was conducted over five months from 1st March 2012 to end of July 2012. A structured questionnaire containing 15 questions on the following items: gender, age, diagnosis, surgical procedure done, expectations before and after surgery, adequacy of counseling given and involvement of family was used to collect data. Nine questions to assess depression were adapted from the Patient Health Questionnaire (PHQ-9.Setting:  The study was conducted at SekuruKaguvi Hospital Eye Unit, Parirenyatwa Group of Hospitals in Harare.Results:  Twenty-eight patients who underwent destructive eye surgery during the study period were selected using systematic random sampling. The gender ratio was 1:1 and the mean age was 38.7 years with a range from 24 to 65 years. Fifty percent of the patients in the study had orbital exenteration while the rest had enucleation (14% and evisceration (36%. Twenty-eight percent of the study population had depression.Conclusion: Destructive eye surgery is frequently associated with depression and our current management protocol of patients

    The increased survival after a severe acquired brain injury (sABI) raise the problem of making most effective the treatments in Intensive Care Unit (ICU)/Neurointensive Care Unit (NICU), also integrating rehabilitation care. Despite previous studies reported that early mobilization in ICU was effective in preventing complications and reducing hospital stay, few studies addressed the rehabilitative management of sABI patients in ICU/NICU. To collect clinical and functional data about the early rehabilitative management of sABI patients during ICU/NICU stay. Prospective, observational, multicenter study. Fourteen facilities supplied by intensive neurorehabilitation units and ICU/NICUs. Consecutive sABI patients admitted to ICU/NICU. Patients were evaluated at admission and then every 3-5 days. Clinical, functional and rehabilitative data, including Glasgow Coma Scale (GCS), Disability Rating Scale (DRS), The Rancho Los Amigos Levels of Cognitive Functioning Scale (LCF), Early Rehabilitation Barthel Index (ERBI), Glasgow Outcome scale (GOS) and Functional Independence Measure (FIM) were collected. One hundred and two patients (F/M 44/58) were enrolled. The mean duration of ICU stay was 24.7±13.9 days and the first rehabilitative evaluation occurred after 8.7±8.8 days. Regular postural changes and multijoint mobilization were prescribed in 63.7% and 64.7% cases, respectively. The mean session duration was 38±11.5 minutes. Swallowing evaluation was performed in 14.7% patients, psychological support was provided to 12.7% of patients' caregivers, while 17.6% received a psycho-educational intervention, and 28.4% were involved in interdisciplinary team meetings. The main discharge destinations were Severe Acquired Brain Injury rehabilitation units for 43.7%, intensive neurorehabilitation units for 20.7%. Data showed that early rehabilitation was not diffusely performed in sABI subjects in ICU/NICU and rehabilitative interventions were variable; one-third of subjects were

    This descriptive observational study was carried out in Guru Teg Bahadur Hospital to identify predictors and outcome of obstetric admission to Intensive Care Unit (ICU). Ninety consecutive pregnant patients or those up to 42 days of termination of pregnancy admitted to ICU from October 2010 to December 2011 were enrolled as study subjects with selection of a suitable comparison group. Qualitative statistics of both groups were compared using Pearson's Chi-square test and Fisher's exact test. Odds ratio was calculated for significant factors. Low socioeconomic status, duration of complaints more than 12 h, delay at intermediary facility, and peripartum hysterectomy increased probability of admission to ICU. High incidence of obstetric admissions to ICU as compared to other countries stresses on need for separate obstetric ICU. Availability of high dependency unit can decrease preload to ICU by 5%. Patients with hemorrhagic disorders and those undergoing peripartum hysterectomy need more intensive care.

  18. Palliative care in a coronary care unit: a qualitative study of physicians' and nurses' perceptions.

    Nordgren, Lena; Olsson, Henny

    2004-02-01

    Earlier research has shown that physicians and nurses are motivated to provide good palliative care, but several factors prevail that prevent the best care for dying patients. To provide good palliative care it is vital that the relationship between nurses and physicians is one based on trust, respect and sound communication. However, in settings such as a coronary care unit, disagreement sometimes occurs between different professional groups regarding care of dying patients. The aim of this study was to describe and understand physicians' and nurses' perceptions on their working relationship with one another and on palliative care in a coronary care unit setting. Using a convenience sample, professional caregivers were interviewed at their work in a coronary care unit in Sweden. Data collection and analysis were done concurrently using a qualitative approach. From the interviews, a specific pattern of concepts was identified. The concepts were associated with a dignified death, prerequisites for providing good palliative care and obstacles that prevented such care. Caregivers who work in a coronary care unit are highly motivated to provide the best possible care and to ensure a dignified death for their patients. Nevertheless, they sometimes fail in their intentions because of several obstacles that prevent good quality care from being fully realized. To improve practice, more attention should be paid to increasing dying patients' well-being and participation in care, improving strategic decision-making processes, offering support to patients and their relatives, and improving communication and interaction among caregivers working in a coronary care unit. Caregivers will be able to support patients and relatives better if there are good working relations in the work team and through better communication among the various professional caregivers.

    Previous to wider prevalence studies, we designed the present pilot study to assess concordance and time invested in patient evaluations using a palliative care needs assessment tool. We also sought to estimate the prevalence of palliative care needs in an acute care hospital unit. A cross-sectional study was carried out, 4 researchers (2 doctors and 2 nurses) independently assessed all inpatients in an acute care hospital unit in Manacor Hospital, Mallorca (Spain), using the validated tool NECPAL CCOMS-ICO©, measuring time invested in every case. Another researcher revised clinical recordings to analise the sample profile. Every researcher assessed 29 patients, 15 men and 14 women, mean age 74,03 ± 10.25 years. 4-observer concordance was moderate (Kappa 0,5043), tuning out to be higher between nurses. Mean time per patient evaluation was 1.9 to 7.72 minutes, depending on researcher. Prevalence of palliative care needs was 23,28%.

    OBJECTIVES: To investigate the functional impact of the interaction of MUC1 with the epidermal growth factor receptors HER3 and HER4 in patients with bladder cancer. PATIENTS AND METHODS: Using reverse transcription quantitative polymerase chain reaction, we examined MUC1 expression in 82 bladder...... cancer biopsies previously examined for the expression of HER3. RESULTS: Patients expressing high MUC1 had a favourable survival when the expression of HER3 was also high compared with when the expression of HER3 was low (P = 0.004). When MUC1 expression was low, HER3 co-expression did not influence...... the prognostic value of MUC1 (P = 0.488). MUC1 expression had no correlation with survival, tumour stage or grade, or to the prognostic value of HER4. CONCLUSIONS: A high MUC1 expression was associated with a favourable prognosis in patients with bladder cancer when the expression of HER3 was also high...

  1. Testing the efficacy of downscaling in species distribution modelling: a comparison between MaxEnt and Favourability Function models

    OpenAIRE

    2016-01-01

    Statistical downscaling is used to improve the knowledge of spatial distributions from broad–scale to fine–scale maps with higher potential for conservation planning. We assessed the effectiveness of downscaling in two commonly used species distribution models: Maximum Entropy (MaxEnt) and the Favourability Function (FF). We used atlas data (10 x 10 km) of the fire salamander Salamandra salamandra distribution in southern Spain to derive models at a 1 x 1 km resolution. Downscaled models were...

    Full Text Available This study deals with one of the most important fundamental rules of criminal trial, both in the United States of America and in Romania, namely the right of the person accused of committing a crime to have a trial within a reasonable time. As regards the legal system of the United States of America, the author approached the issue from the perspective of the Constitution of the United States of America, respectively reviewing the legislative system of the State of Illinois. The presentation of the case law in this field had an important role in this review. As regards the legal system of Romania, the efforts to amend the legislation in order to ensure a reasonable time for carrying out the criminal proceedings are obvious even if sometimes, in this way, the applicability of other fundamental principles, such as the principle of finding out the truth, is restricted. The differences existing between the two penal legal systems are also obvious, after reading this study.

    Full Text Available Work life balance plays an important role now a day. Employees want it, managers need it, and organization cannot afford to ignore it! Managers need to take work-life balance seriously particularly in garment units. The more overworked and overloaded, the higher the demands or the expectations on the department or the work unit, the more the managers have to rely on their employees to produce at the highest possible level of efficiency, effectiveness, and quality. If managers are out of balance or stressed or sick then they will be less committed to the outcomes, they will be less committed to the organization, they will be less committed to the client, the product or goods or service that they are producing. This research paper examined the work life balance amongst managers of garment units in Tamil nadu state. The methodology adopted for the study was descriptive research design. Data were collected from 480 managers through questionnaire method around Tamilnadu state, India. In the present study, stastical tools such as percentage analysis, mean value, chi-square, ANOVA, and correlation analysis were used for the analysis. The results indicated that the work life balance of managers are not completely successful due to their present working hours, working environment and increase in products prices, work load, responsibilities in work and  decrease of job security due to recession.

    One-carbon unit transfer reaction of folate cofactor model compound, 1-acetyl-2-methyl-imidazolinium, with 1,2-diaminobenzene has been studied theoretically with ONIOM method. The result shows that there are two pathways to complete this reaction because the imidazolinium ring has two breaking patterns. Both the two pathways have six steps. They are combination of two reactants, proton migration, break of five-membered ring, formation of benzimidazole derivate, another proton migration, and formation of final products. In each of the above pathways, the two proton migration steps have higher energy, which illuminate that the reaction is catalyzed by general acid-base. This fact agrees with the experimental results of enzymatic one-carbon unit transfer at oxidation level of formate.

    2014-09-01

    Young men in Western cultures frequently engage in body depilation practices, but little is known regarding how such bodies are perceived. This exploratory study asked United States college students (N=238) to view six pictures of the same male body with different amounts of visible body hair and to indicate which body was most sexually attractive to themselves, to most men, and to most women. Both men and women chose a relatively hairless male body as the most sexually attractive. Women, however, thought men would choose a hairier body than men actually did. Most of the men reduced or removed body hair, especially from the pubic area. Questionnaire responses indicated that men and women had similar attitudes toward men's body hair, with both hair reduction and hair retention being socially acceptable. Men's body depilation, while still optional, may be becoming normative, at least among United States college students.

  6. Nutritional status among older residents with dementia in open versus special care units in municipal nursing homes: an observational study

    Science.gov (United States)

    2013-01-01

    Background Undernutrition is widespread among institutionalised elderly, and people suffering from dementia are at particularly high risk. Many elderly with dementia live in open units or in special care units in nursing homes. It is not known whether special care units have an effect on the nutritional status of the residents. The aim of this study was therefore to examine the nutritional status of residents with dementia in both open units and in special care units. Methods Among Oslo’s 29 municipal nursing homes, 21 participated with 358 residents with dementia or cognitive impairment, of which 46% lived in special care units. Nutritional status was assessed using the Malnutrition Universal Screening Tool and anthropometry. Results We found no differences (p > 0.05) in risk of undernutrition, body mass index, mid-upper arm muscle circumference or triceps skinfold thickness between residents in open units and those in special care units. Residents in special care units were significantly younger and stronger when measured with a hand-grip test. Conclusions We found no difference in nutritional status between nursing home residents with dementia/cognitive impairment in open units versus in special care units. PMID:23496975

    to prospectively evaluate the risk of acute myocardial infarction (AMI) associated with non-fasting triglyceride levels. a health survey of 140,790 Norwegians free of known coronary heart disease at baseline (1994-2003) were followed through December 2009 via record linkages to the Cause of Death Registry and hospital discharge diagnoses in the CVDNOR project, and evaluated in Cox proportional hazards analyses. a total of 3219 (4.8%) men and 1434 (1.9%) women developed an AMI. Women had a steeper gradient risk with increasing triglyceride decile than men, where the highest (≥2.88 mmol/l) compared to the lowest decile (triglyceride interaction term was observed. HRs increased with increasing triglyceride quartile in participants with a favourable HDL-C after multivariable adjustment (p for trend triglycerides did not significantly predict AMI among those with low HDL-C. For those with favourable HDL-C, net reclassification index identified a 10% and 14% improvement in classification for men and women, respectively. non-fasting triglyceride levels among individuals with favourable HDL-C may help identify a subset of individuals at risk for CHD. Further research is warranted in evaluating non-fasting triglycerides in CHD prediction. © The European Society of Cardiology 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Objective To evaluate Candida parapsilosis candidaemia in a neonatal unit over 7 years. Design Case series study. Setting A 2000-bed tertiary-care university hospital at São Paulo, Brazil. Participants Neonates hospitalised in a 63-bed neonatal unit. Primary and secondary outcome measures We evaluated the incidence of C parapsilosis fungemia in a neonatal unit from 2002 through 2008 and the main microbiological, clinical and epidemiological aspects of this disease in neonates. During the study period an outbreak occurred, an infection control programme was implemented, and isolates from blood and hand healthcare workers (HCWs) were submitted to molecular typing. Results During 7 years, there were 36 cases of C parapsilosis fungaemia and annual incidence varied from 0 to 19.7 per 1000 admissions. Evaluating 31 neonates with fungemia, the mean age at diagnosis was 19 days. All children except for one were premature; all had received total parenteral nutrition and all but one had used central venous catheter. Three neonates had received antifungal treatment previously to the diagnosis. Thirty-day mortality was 45%. Only lower birthweight was associated with mortality. C parapsilosis species complex was isolated from hand cultures in eight (11%) of the HCWs (one isolate was identified as C orthopsilosis). By molecular typing no HCW isolate was similar to any of the blood isolates. Conclusions The incidence of C parapsilosis fungemia in a neonatal unit varied widely over 7 years. We observed in our series a higher death rate than that reported in European countries and the USA. PMID:22869093

    2014-06-01

    Full Text Available Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental conditions above the threshold for a positive carbon balance, benefitting evergreen woody species more than deciduous ones. The comparatively lower solar energy input in winter decreases the foliar light saturation point. This leads to a higher susceptibility to photoinhibitory stress especially when chilly (Quercus ilex L., Pinus halepensis Mill., and Arbutus unedo L. during a period of mild winter conditions and their responses to a sudden cold period. The state of the photosynthetic machinery in both periods was thus tested by estimating the foliar photosynthetic potential with CO2 response curves in parallel with chlorophyll fluorescence measurements. The studied evergreen tree species benefited strongly from mild winter conditions by exhibiting extraordinarily high photosynthetic potentials similar to those under spring conditions. A sudden period of frost, however, negatively affected the photosynthetic apparatus, leading to significant decreases in key physiological parameters such as the maximum carboxylation velocity (Vc, max, the maximum photosynthetic electron transport rate (Jmax, and the optimal fluorometric quantum yield of photosystem II (Fv/Fm. This change persisted for several weeks after the cold period despite the recovery of the temperature to the conditions previous to the frost event. The responses of Vc, max and Jmax were highly species-specific, where Q. ilex exhibited the highest and P. halepensis the lowest reductions. In contrast, the optimal fluorometric quantum yield of photosystem II (Fv/Fm was significantly lower in A. unedo after the cold period. The leaf position played an important role in Q. ilex showing a comparatively stronger winter effect on sunlit leaves. Our results generally agreed with

    2013-12-01

    Full Text Available Distribution transformer is one of the most important power equipments in distribution network, whose running state exercises a great influence on the stability of the network. Transformer Terminal Unit (TTU is an effective device to monitor the running state of transformers in the distribution automation system. In this paper, we study a new smart TTU which uses ARM7 series chip as processor, equipped with ATT7022B based electric meter module and GPRS module for remote data transmission control. We focus on the corresponding hardware, software design and the measurement principle of harmonics of TTU. The new TTU can measure the electric parameters of the distribution transformer precisely. Taking advantage of the powerful ARM processor, it can analyze harmonic of the power line effectively. Due to the always-on-line feature of GPRS, TTU can achieve reliable communication with the remote terminal and the master station. Compared with other similar units, the new unit outperforms in terms of real-time, precision and reliability, which can fully meet with the high-speed development of distribution automation system.

    Full Text Available Critical care patients benefit from the attention of nursing personnel with a high competence level. The aim of the study was to describe and evaluate the self-assessed basic competence of intensive care unit nurses and related factors. A cross-sectional survey design was used. A basic competence scale (Intensive and Critical Care Nursing Competence Scale version 1, Likert scale 1–5, 1 = poor and 5 = excellent was employed among Finnish intensive care unit nurses (n=431. Intensive care unit nurses’ self-assessed basic competence was good (mean 4.19, SD 0.40. The attitude and value base of basic competence was excellent whereas experience base was the poorest compared to the knowledge base and skill base of intensive and critical care nursing. The strongest factor explaining nurses’ basic competence was their experience of autonomy in nursing care (F value 60.85, β 0.11, SE 0.01, and P≤0.0001. Clinical competence was self-rated as good. Nurses gave their highest competence self-ratings for ICU patient care according to the principles of nursing care. The ICU nurses also self-rated their professional competence as good. Collaboration was self-rated as the best competence. In basic and continuing education and professional self-development discussions it is meaningful to consider and find solutions for how to improve nurses’ experienced autonomy in nursing.

    Many countries are on the brink of establishing antibiotic stewardship programmes in hospitals nationwide. In a previous study we found that communication between microbiology laboratories and clinical units is a barrier to implementing efficient antibiotic stewardship programmes in Norway. We have now addressed the key communication barriers between microbiology laboratories and clinical units from a laboratory point of view. Qualitative semi-structured interviews were conducted with 18 employees (managers, doctors and technicians) from six diverse Norwegian microbiological laboratories, representing all four regional health authorities. Interviews were recorded and transcribed verbatim. Thematic analysis was applied, identifying emergent themes, subthemes and corresponding descriptions. The main barrier to communication is disruption involving specimen logistics, information on request forms, verbal reporting of test results and information transfer between poorly integrated IT systems. Furthermore, communication is challenged by lack of insight into each other's area of expertise and limited provision of laboratory services, leading to prolonged turnaround time, limited advisory services and restricted opening hours. Communication between microbiology laboratories and clinical units can be improved by a review of testing processes, educational programmes to increase insights into the other's area of expertise, an evaluation of work tasks and expansion of rapid and point-of-care test services. Antibiotic stewardship programmes may serve as a valuable framework to establish these measures.

    Among the microorganism involved in environmental contamination, Legionella spp is actually considered an important infectious hazard. The aim of this study is to evaluate the incidence of Legionella spp in water samples collected from 138 dental unit selected from public outpatient clinics of 6 Italian cities. The samples were taken from oral rinsing cup, air-water syringe, ultrasonic scaler and the turbine to investigate Legionella spp, Pseudomonas aeruginosa and the total heterotrophic count at 36 degrees and 22 degrees. Legionella spp was present in 33,3% dental unit water; but a significant difference was shown among the enrolled cities. In 43,5% of water sample Legionella concentration was 1.000-10.000 CFU/L and in 30,4% was >10.000 CFU/L. L. pneumophila 1 was found in 23,9% of water samples. The results demonstrate that the concentration of Legionella spp in dental unit water lines could be high and this suggests that the exposure to these micoorganism during the dental practise could be a potential health risk both for dental personnel and for the patients too, especially when immunocompromised.

    To investigate the risk effects of poverty and exposure to collective violence attributed to organized crime on the mental health of children living on the United States-Mexico border. A repeated, cross-sectional study measured risk effects by comparing scores of psychosocial and behavioral problems among children and adolescents living on the border in the United States or Mexico in 2007 and 2010. Patients living in poverty who responded once to the Pictorial Child Behavior Checklist (P+CBCL) in Spanish were randomly selected from clinics in El Paso, Texas, United States (poverty alone group), and Ciudad Juarez, Chihuahua, Mexico (poverty plus violence group). Only children of Hispanic origin (Mexican-American or Mexican) living below the poverty level and presenting at the clinic for nonemergency visits with no history of diagnosed mental, neurological, or life-threatening disease or disability were included. Exposure to collective violence and poverty seemed to have an additive effect on children's mental health. Children exposed to both poverty and collective violence had higher problem scores, as measured by the P+CBCL, than those exposed to poverty alone. It is important to consider that children and adolescents exposed to collective violence and poverty also have fewer chances to receive treatment. Untreated mental health problems predict violence, antisocial behaviors, and delinquency and affect families, communities, and individuals. It is crucial to address the mental health of children on the border to counteract the devastating effects this setting will have in the short term and the near future.

    2016-10-01

    Morning interprofessional rounds (MIRs) are used in critical care medicine to improve team-based care and patient outcomes. Given existing evidence of conflict between and dissatisfaction among rounds participants, this study sought to better understand how the operational realities of care delivery in the intensive care unit (ICU) impact the success of MIRs. We conducted a year-long comparative ethnographic study of interprofessional collaboration and patient and family involvement in four ICUs in tertiary academic hospitals in two American cities. The study included 576 h of observation of team interactions, 47 shadowing sessions and 40 clinician interviews. In line with best practices in ethnographic research, data collection and analysis were done iteratively using the constant comparative method. Member check was conducted regularly throughout the project. MIRs were implemented on all units with the explicit goals of improving team-based and patient-centered care. Operational conditions on the units, despite interprofessional commitment and engagement, appeared to thwart ICU teams from achieving these goals. Specifically, time constraints, struggles over space, and conflicts between MIRs' educational and care-plan-development functions all prevented teams from achieving collaboration and patient-involvement. Moreover, physicians' de facto control of rounds often meant that they resembled medical rounds (their historical predecessors), and sidelined other providers' contributions. This study suggests that the MIRs model, as presently practiced, might not be well suited to the provision of team-based, patient-centered care. In the interest of interprofessional collaboration, of the optimization of clinicians' time, of high-quality medical education and of patient-centered care, further research on interprofessional rounds models is needed.

    Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental conditions above the threshold for a positive carbon balance, benefitting evergreen woody species more than deciduous ones. The comparatively lower solar energy input in winter decreases the foliar light saturation point. This leads to a higher susceptibility to photoinhibitory stress especially when chilly (compensates for the lower carbon uptake during spring and summer in comparison to deciduous species. We investigated the ecophysiological behaviour of three co-occurring mature evergreen tree species (Quercus ilex L., Pinus halepensis Mill., and Arbutus unedo L.). Therefore, we collected twigs from the field during a period of mild winter conditions and after a sudden cold period. After both periods, the state of the photosynthetic machinery was tested in the laboratory by estimating the foliar photosynthetic potential with CO2 response curves in parallel with chlorophyll fluorescence measurements. The studied evergreen tree species benefited strongly from mild winter conditions by exhibiting extraordinarily high photosynthetic potentials. A sudden period of frost, however, negatively affected the photosynthetic apparatus, leading to significant decreases in key physiological parameters such as the maximum carboxylation velocity (Vc, max), the maximum photosynthetic electron transport rate (Jmax), and the optimal fluorometric quantum yield of photosystem II (Fv/Fm). The responses of Vc, max and Jmax were highly species specific, with Q. ilex exhibiting the highest and P. halepensis the lowest reductions. In contrast, the optimal fluorometric quantum yield of photosystem II (Fv/Fm) was significantly lower in A. unedo after the cold period. The leaf position played an important role in Q. ilex showing a stronger winter effect on sunlit leaves in

    As needed (PRN) oral opioid analgesics are an integral part of many orthopedic postoperative multimodal pain management regimens. However, the unpredictable nature of this dosing method can lead to disruptions in the process of administering the medication, as well as be an interruption to regular nursing activities. This IRB approved quantitative time study tested the hypothesis that a significant amount of nursing time is required in the administration of PRN oral opioid analgesics on a postoperative orthopedic nursing unit. The purpose of this study is to evaluate the time necessary to complete the required steps related to the administration of PRN oral analgesics. Nurses from 28 nursing shifts used a personal digital assistant (PDA) to record the time needed to complete these steps. We determined that 10.9 minutes is the mean time required to administer PRN oral analgesics on this unit. Other time studies have evaluated the medication administration process as a whole. No time studies related to PRN oral analgesic administration have been reported. In phase I of our project, the data were summarized and will be used as a baseline comparison for phase II, in which we will evaluate an oral PCA medication administration system.

    2013-01-01

    The purpose of this case study was to examine environmental variables that lead to staff error in acute care settings: noise; lighting; ergonomics, furniture, and equipment; and patient room design and unit layout. Chaudhury, Mahmood, & Valente (2009) reviewed a number of design considerations related to reducing errors by nursing staff in acute care settings. The Neurological Rehabilitation Unit (NRU) at one hospital served to further examine the design recommendations outlined by Chaudhury et al. (2009). Based on photographs, a site tour, interviews with the NRU manager and with the son of a patient of 5 months, comparisons were made between the NRU and the acute care setting design considerations reviewed by Chaudhury et al. (2009). The NRU appeared to comply with many recommendations: enforced noise reduction was facilitated through limiting both the number of patients per room and the number of patients admitted to the unit. Distinct rooms were used for various tasks that helped to contain activity-based noise. A combination of daylighting and artificial lighting was in place, but efforts to control glare and thermal comfort were not integrated into the design. The ergonomic needs of employees were incorporated in the design of the NRU, and the layouts of patient rooms and the layout of the NRU in general also were compatible with the design recommendations reviewed by Chaudhury et al.

    The accuracy and repeatability of an inertial measurement unit (IMU) system for directly measuring trunk angular displacement and upper arm elevation were evaluated over eight hours (i) in comparison to a gold standard, optical motion capture (OMC) system in a laboratory setting, and (ii) during a field-based assessment of dairy parlour work. Sample-to-sample root mean square differences between the IMU and OMC system ranged from 4.1° to 6.6° for the trunk and 7.2°-12.1° for the upper arm depending on the processing method. Estimates of mean angular displacement and angular displacement variation (difference between the 90th and 10th percentiles of angular displacement) were observed to change IMU system may serve as an acceptable instrument for directly measuring trunk and upper arm postures in field-based occupational exposure assessment studies with long sampling durations. Practitioner Summary: Few studies have evaluated inertial measurement unit (IMU) systems in the field or over long sampling durations. Results of this study indicate that the IMU system evaluated has reasonably good accuracy and repeatability for use in a field setting over a long sampling duration.

    Worldwide, various autopsy studies have shown a decrease in the diagnostic error rate over the last years. The cause of this positive development is mainly due to the improvement of modern medicine. However, intensive care unit patients are thought to have a higher risk for diagnostic errors, which is documented in several studies in the adult population. In contrast, there is only limited information about diagnostic errors in pediatrics, particularly in pediatric and neonatal intensive care units. The aims of this study were to analyze the spectrum of childhood death, determine the prevalence and distribution of autopsy-confirmed diagnostic errors, and describe patient characteristics that might have influenced the discordance between antemortem and postmortem findings. We analyzed 143 autopsy reports from 2004 to 2013 and correlated these with clinical reports. The overall autopsy rate during this interval was 20.3%. The leading causes of death were congenital malformations (28%), diseases closely associated with perinatal disorders (25%), disorders of the cardiovascular system (18%), and infections (15%). Additional findings were obtained in 23% of the autopsies. Major diagnostic errors were found in 6%, the lowest reported value in a developed country as yet. Most cases (75%) showed complete concordance between clinical diagnoses and postmortem findings, in line with improvements in diagnostic and therapeutic processes over the last decades. In conclusion, autopsy of neonates, infants, and children represents an important tool for monitoring the quality of pediatric and neonatal medical care.

  15. Colombians in the United States: A Study of Their Well-Being

    Full Text Available This study examined the extent to which four factors—acculturation, ethnic identity, self-esteem, and resilience—can explain the well-being of Colombian immigrants in the United States across three waves of immigration (wave 1, from 1945–1964; wave 2, from 1965–1989; and wave 3, from 1990–2008. The results indicate that of the four factors, self-esteem most correlated with and was a predictor of well-being. Participants exhibited high levels of well-being as their level of self-esteem increased. Ethnic identity negatively predicted well-being, especially for men who entered during wave 3; as the extent of their ethnic identity increased, their well-being decreased. Correspondingly, Colombians who entered as political refugees reported a lower level of well-being. This research was groundbreaking in assessing factors contributing to the well-being of Colombian immigrants and assisting in the search for appropriate scales to study this population. Although its results have to be considered with caution, the study opens doors to future research, policies, and programs regarding the mental health assessment and treatment of Colombians in the United States.

    Full Text Available Objectives. We conducted a one-year observational study from December 2012 to November 2013 to describe the epidemiology of bacteraemia in intensive care units (ICU of Mohammed V Military Teaching Hospital of Rabat (Morocco. Methods. The study consisted of monitoring all blood cultures coming from intensive care units and studying the bacteriological profile of positive blood cultures as well as their clinical significance. Results. During this period, a total of 46 episodes of bacteraemia occurred, which corresponds to a rate of 15,4/1000 patients. The rate of nosocomial infections was 97% versus 3% for community infections. The most common source of bacteraemia was the lungs in 33%, but no source was identified in 52% of the episodes. Gram negative organisms were isolated in 83,6% of the cases with Acinetobacter baumannii being the most frequent. Antibiotic resistance was very high with 42,5% of extended-spectrum beta-lactamases (ESBLs in Enterobacteriaceae and 100% of carbapenemase in Acinetobacter baumannii. The antibiotherapy introduced in the first 24 hours was adequate in 72% of the cases. Conclusions. Bloodstream infections in ICU occur most often in patients over 55 years, with hypertension and diabetes. The bacteria involved are mainly Gram negative bacteria multiresistant to antibiotics. Early administration of antibiotics significantly reduces patients mortality.

    Aggression and violence on acute psychiatric inpatient units is extensive and leads to negative sequelae for staff and patients. With increasingly acute inpatient milieus due to shorter lengths of stay, inpatient staff is limited in training and time to be able to provide treatments. Mobile technology provides a new platform for offering treatment on such units, but it has not been tested for feasibility or usability in this particular setting. The aim of this study was to examine the feasibility, usability, and acceptability of a brief mindfulness meditation mobile phone app intended to reduce anger and aggression in acute psychiatric inpatients with schizophrenia, schizoaffective disorder, or bipolar disorder, and a history of violence. Participants were recruited between November 1, 2015 and June 1, 2016. A total of 13 inpatients at an acute care state hospital carried mobile phones for 1 week and were asked to try a commercially available mindfulness app called Headspace. The participants completed a usability questionnaire and engaged in a qualitative interview upon completion of the 7 days. In addition, measures of mindfulness, state and trait anger, and cognitive ability were administered before and after the intervention. Of the 13 enrolled participants, 10 used the app for the 7 days of the study and completed all measures. Two additional participants used the app for fewer than 7 days and completed all measures. All participants found the app to be engaging and easy to use. Most (10/12, 83%) felt comfortable using Headspace and 83% (10/12) would recommend it to others. All participants made some effort to try the app, with 6 participants (6/12, 50%) completing the first 10 10-minute "foundation" guided meditations. This is the first known study of the use of a commercially available app as an intervention on acute psychiatric inpatient units. Acutely ill psychiatric inpatients at a state hospital found the Headspace app easy to use, were able to complete

    The major cause of hyperphenylalaninemia is mutations in the gene encoding phenylalanine hydroxylase (PAH). The known mutations have been identified primarily in European patients. The purpose of this study was to determine the spectrum of mutations responsible for PAH deficiency in the United States. One hundred forty-nine patients enrolled in the Maternal PKU Collaborative Study were subjects for clinical and molecular investigations. PAH gene mutations associated with phenylketonuria (PKU) or mild hyperphenylalaninemia (MHP) were identified on 279 of 294 independent mutant chromosomes, a diagnostic efficiency of 95%. The spectrum is composed of 71 different mutations, including 47 missense mutations, 11 splice mutations, 5 nonsense mutations, and 8 microdeletions. Sixteen previously unreported mutations were identified. Among the novel mutations, five were found in patients with MHP, and the remainder were found in patients with PKU. The most common mutations were R408W, IVS12nt1g{r_arrow}a, and Y414C, accounting for 18.7%, 7.8% and 5.4% of the mutant chromosomes, respectively. Thirteen mutations had relative frequencies of 1%-5%, and 55 mutations each had frequencies {le}1%. The mutational spectrum corresponded to that observed for the European ancestry of the U.S. population. To evaluate the extent of allelic variation at the PAH locus within the United States in comparison with other populations, we used allele frequencies to calculate the homozygosity for 11 populations where >90% ascertainment has been obtained. The United States was shown to contain one of the most heterogeneous populations, with homozygosity values similar to Sicily and ethnically mixed sample populations in Europe. The extent of allelic heterogeneity must be a major determining factor in the choice of mutation-detection methodology for molecular diagnosis in PAH deficiency. 47 refs., 1 fig., 5 tabs.

    This international, cross-cultural study investigated the attitudes of occupational therapy students from Australia, United Kingdom, United States and Taiwan towards inclusive education for students with disabilities. The possible impact of professional education on students' attitudes was also explored. A total of 485 students from 11 entry-level occupational therapy education programmes from Australia, the United Kingdom, the United States and Taiwan participated in the study. Among them, 264 were freshmen (first-year students) and 221 were seniors (final-year students). Data collected from a custom-designed questionnaire were analysed both quantitatively and qualitatively. In general, the occupational therapy students reported having positive attitudes towards inclusion. Considerable differences, however, existed among the student groups from the four countries. Professional education appeared to have a significant impact on students' attitudes towards inclusion from first year to senior year. Although students were in favour of inclusion, they also cautioned that their support for inclusive practices depended on various factors such as adequate preparation, support and assistance to students with disabilities. Limitations of the study included the small, convenience sample and different degree structures of the participating programmes. Future research studies need to compare occupational therapy students' attitudes with students from other health care professions. A longitudinal study on the impact of the professional education programme on students' attitudes towards inclusive education is warranted.

    2013-01-01

    The purpose of this study was to explore the strategies used by nurse managers in Japan to facilitate the integration of newly graduate nurses (NGNs) into their clinical units. The integration of NGNs into clinical units is an important issue for both NGNs and nurse managers because the first year of practice plays a vital role in a NGN's career. Data were generated through semi-structured interviews with 9 nurse managers in 9 acute care hospitals. Data analysis was conducted using a qualitative content analysis method. Nurse managers used a total of 6 strategies: understanding the circumstances of NGNs, providing opportunities for experience and learning, supporting nurses who teach NGNs, facilitating self-learning, promoting awareness of being a nurse in the clinical unit, and strengthening the sense of comradeship in clinical units. Three of these strategies were particularly important for NGNs' integration into clinical units: facilitating self-learning, promoting awareness of being a nurse in the clinical unit, and strengthening the sense of comradeship in clinical units. These strategies were described in this study. The strategies adopted by nurse managers should be aimed at all nurses, not just NGNs, in order to strengthen the sense of comradeship in clinical units. This approach would create a supportive environment for the integration of NGNs into clinical units. The strategies presented in this study can be utilized not just by nurse managers but all senior nurses in the unit. NGNs can use these strategies to help them understand what they need to do to become a full member of their unit.

    The SMOS space mission will soil moisture over the continents and ocean surface salinity with the sufficient resolution to be used in global climate change studies. With the aim of validating SMOS land data and products at the Valencia Anchor Station site (VAS) in a Mediterranean Ecosystem area of Spain, we have designed a sample methodology using a subdivision of the landscape in environmental units related to the spatial variability of soil moisture (Millán-Scheiding, 2006; Lopez-Baeza, et al. 2008). These physio-hydrological units are heterogeneously structured entities which present a certain degree of internal uniformity of hydrological parameters. The units are delimited by integrating areas with the same physio-morphology, soil type, vegetation, geology and topography (Flugel, et al 2003; Millán-Scheiding et al, 2007). Each of these units presented over the same pedological characteristics, vegetation cover, and landscape position should have a certain degree of internal uniformity in its hydrological parameters and therefore similar soil moisture (SM). The main assumption for each unit is that the dynamical variation of the hydrological parameters within one unit should be minimum compared to the dynamics of another unit. This methodology will hopefully provide an effective sampling design consisting of a reduced number of measuring points, sparsely distributed over the area, or alternatively, using SM validation networks where each sampling point is located where it is representative of the mean soil moisture of a complete unit area. The Experimental Plan for the SMOS Validation Rehearsal Campaign at the VAS area of April-May 2008 used this environmental subdivision in the selection and sampling of over 21.000 soil moisture points in a control area of 10 x 10 km2. The ground measurements were carried out during 4 nights corresponding to a drying out period of the soil. The sampling consisted of 700 plots with 4 volumetric SM cylinders and 7 Delta-T Theta

    Water quality in groundwater resources used for public drinking-water supply in the Western San Joaquin Valley (WSJV) was investigated by the USGS in cooperation with the California State Water Resources Control Board (SWRCB) as part of its Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project. The WSJV includes two study areas: the Delta–Mendota and Westside subbasins of the San Joaquin Valley groundwater basin. Study objectives for the WSJV study unit included two assessment types: (1) a status assessment yielding quantitative estimates of the current (2010) status of groundwater quality in the groundwater resources used for public drinking water, and (2) an evaluation of natural and anthropogenic factors that could be affecting the groundwater quality. The assessments characterized the quality of untreated groundwater, not the quality of treated drinking water delivered to consumers by water distributors.The status assessment was based on data collected from 43 wells sampled by the U.S. Geological Survey for the GAMA Priority Basin Project (USGS-GAMA) in 2010 and data compiled in the SWRCB Division of Drinking Water (SWRCB-DDW) database for 74 additional public-supply wells sampled for regulatory compliance purposes between 2007 and 2010. To provide context, concentrations of constituents measured in groundwater were compared to U.S. Environmental Protection Agency (EPA) and SWRCB-DDW regulatory and non-regulatory benchmarks for drinking-water quality. The status assessment used a spatially weighted, grid-based method to estimate the proportion of the groundwater resources used for public drinking water that has concentrations for particular constituents or class of constituents approaching or above benchmark concentrations. This method provides statistically unbiased results at the study-area scale within the WSJV study unit, and permits comparison of the two study areas to other areas assessed by the GAMA Priority Basin Project

    Two series of novel sorafenib analogs containing a sulfonylurea unit were synthesized and their chemical structures were confirmed by ¹H-NMR, ¹³C-NMR, MS spectrum and elemental analysis. The synthesized compounds were evaluated for the cytotoxicity against A549, Hela, MCF-7, and PC-3 cancer cell lines. Some of the compounds showed moderate cytotoxic activity, especially compounds 1-(2,4-difluorophenylsulfonyl)-3-(4-(2-(methylcarbamoyl)pyridin-4-yloxy)phenyl)urea (6c) and 1-(4-bromophenylsulfonyl)-3-(4-(2-(methylcarbamoyl)pyridin-4-yloxy)phenyl)urea (6f) with the IC50 values against four cancer cell lines ranging from 16.54±1.22 to 63.92±1.81 μM, respectively. Inhibitory rates against vascular endothelial growth factor receptor-2 (VEGFR2/KDR) kinase at 10 μM of target compounds were further carried out in this paper in order to investigate the target of these compounds. Structure-activity relationships (SARs) and docking studies indicated that the sulfonylurea unit was important to these kinds of compounds. None of the substitutions in the phenoxy group and small halogen atoms such as 2,4-difluoro substitution of the aryl group contributed to the activity. The results suggested that sulfonylurea sorafenib analogs are worthy of further study.

    A Grand Canonical Monte Carlo scheme, based on united events combining protonation/deprotonation and insertion/deletion of HCl molecules is proposed for the generation of polyaniline structures at intermediate doping levels between 0% (PANI EB) and 100% (PANI ES). A procedure based on this scheme and subsequent structure relaxations using molecular dynamics is described and validated. Using the proposed scheme and the corresponding procedure, atomistic models of amorphous PANI-HCl structures were generated and studied at different doping levels. Density, structure factors, and solubility parameters were calculated. Their values agree well with available experimental data. The interactions of HCl with PANI have been studied and distribution of their energies has been analyzed. The procedure has also been extended to the generation of PANI models including adsorbed water and the effect of inclusion of water molecules on PANI properties has also been modeled and discussed. The protocol described here is general and the proposed United Event Grand Canonical Monte Carlo scheme can be easily extended to similar polymeric materials used in gas sensing and to other systems involving adsorption and chemical reactions steps.

    The Par Pond unit designated under CERCLA consists of sediments within a Savannah River Site (SRS) cooling water reservoir. The sediments are contaminated with radionuclides and nonradioactive constituents from nuclear production reactor operations. The mercury in Par Pond is believed to have originated from the Savannah River. Because of Par Pond Dam safety Issues, the water level of the reservoir was drawn down, exposing more than 1300 acres of contaminated sediments and triggering the need for CERCLA interim remedial action. This paper presents the interim action approach taken with Par Pond as a case study. The approach considered the complexity of the Par Pond ecosystem, the large size of Par Pond, the volume of contaminated sediments, and the institutional controls existing at SRS.

    Full Text Available Objective: To evaluate drug utilization and associated costs for the treatment of patients admitted in burn care unit of a tertiary care hospital. Methods: A prospective cross sectional study was conducted for a period of 15 months at Basaweshwara Teaching and General Hospital (BTGH, Gulbarga and the data collected was analyzed for various drug use indicators. Results: A total of 100 prescriptions were collected with 44% belonging to males and 56% to females. The average number of drugs per prescription ranged from 4.5 to 9.5. 9.5% of generics and 92% of essential drugs were prescribed. The opioid analgesics and sedatives were prescribed to all the patients who were admitted in burn care unit. The (Defined daily dose DDD/1 000/day for amikacin (359 was the highest followed by diclofenac sodium (156, pantoprazole (144, diazepam (130, ceftazidime (124, tramadol (115, ceftriaxone (84 and for paracetamol (4 which was the lowest. Conclusions: Significant amount of the money was spent on procurement of drugs. Most of the money was spent on prescribed antibiotics. The prescription of generic drugs should be promoted, for cost effective treatment. Hence the results of the present study indicate that there is a considerable scope for improvement in the prescription pattern.

    Full Text Available Managing workplace diversity has become a priority concern among organizations in the United Arab Emirates (UAE today. The UAE has one of the world's largest net migration rates, and the number of workers from India, the Philippines, Indonesia, Australia, the USA, among other countries, has increased significantly in recent decades. The UAE's cross-border mobility has resulted in the interaction of people with diverse language, customs and ethnic backgrounds. Although diversity has been shown to have a number of benefits, including enhanced employee creativity and competence, this recognition is often found more in theory than actual practice. Diversity can also lead to miscommunication, dysfunctional adaptation behaviors and the creation of barriers that reduce the benefits diversity can bring to the organization. Due to the nature of the UAE workplace, which is dominated by a foreign workforce, this study critically analyzes the benefits and challenges organizations face in the diverse workplaces of the United Arab Emirates. The study used a multi-method approach combining survey data from 450 surveys of foreign workers with qualitative data from interviews with native officials of organizations. It is an attempt to compare the views of UAE workplace experience from two different groups—non-native workers and native officials. The research found a generally favorable view toward workplace diversity from the perspective of surveyed employees. However, when asked more detailed questions about company policy, a significant segment of respondents expressed reservations about their employer’s ability to implement successful intercultural communication and diversity practices.

In the United Arab Emirates, a country where the rate of obesity is dramatically increasing bariatric surgery has gained popularity in recent years; however, published data on its outcomes in the Emirati population are lacking.Methods: We retrospectively reviewed the medical records of 95 patients who underwent bariatric surgery (ie, laparoscopic Roux-en-Y gastric bypass [RYGB] or laparoscopic sleeve gastrectomy at the Rashid Center for Diabetes and Research in Ajman, United Arab Emirates. Weight outcomes and metabolic marker data were abstracted at baseline and at 3, 6, and 12 months postoperatively.Results: Laparoscopic RYGB was the main procedure performed by our bariatric unit. All variables demonstrated postoperative improvement. An average excess weight loss of 68% was observed at 12 months. Fat mass was the body component that decreased the most, with an average reduction of 46%. Additionally, lipid profiles were significantly different (P<0.01 at 12 months, with triglyceride levels improving by 27% and low-density lipoprotein levels improving by 21%. Similarly, glycated hemoglobin (HbA1c levels decreased significantly (P<0.001 in patients with type 2 diabetes, with an average reduction of 73%.Conclusion: Our results show that a substantial short-term reduction in weight and significant improvements in metabolic markers followed bariatric surgery in severely obese Emirati patients. Our results are consistent with the outcomes of other internationally published studies. Additional studies are warranted to determine whether

    Prior to the acquisition of land by the U.S. Department of War in February 1943 and the creation of the Hanford Site, the land along the Columbia River was home to over 1000 people. Farming and orchard operations by both homesteaders and commercial organizations were prevalent. Orchard activities and the associated application of lead arsenate pesticide ceased in 1943, when residents were moved from the Hanford Site at the beginning of the Manhattan Project. Today, the residues from historical application of lead arsenate pesticide persist in some locations on the Hanford Site. In 2012, the U.S. Department of Energy, U.S. Environmental Protection Agency, and Washington State Department of Ecology established the 100-OL-1 Operable Unit (OU) through the Hanford Federal Facility Agreement and Consent Order, known as the Tri-Party Agreement. The pre-Hanford orchard lands identified as the 100-OL-1 OU are located south of the Columbia River and east of the present-day Vernita Bridge, and extend southeast to the former Hanford townsite. The discontinuous orchard lands within 100-OL-1 OU are approximately 20 km2 (5000 ac). A pilot study was conducted to support the approval of the remedial investigation/feasibility study work plan to evaluate the 100-OL-1 OU. This pilot study evaluated the use of a field portable X-ray fluorescence (XRF) analyzer for evaluating lead and arsenic concentrations on the soil surface as an indicator of lead arsenate pesticide residues in the OU. The objectives of the pilot study included evaluating a field portable XRF analyzer as the analytical method for decision making, estimating the nature and extent of lead and arsenic in surface soils in four decision units, evaluating the results for the purpose of optimizing the sampling approach implemented in the remedial investigation, and collecting information to improve the cost estimate and planning the cultural resources review for sampling activities in the remedial investigation.

    Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

    Full Text Available BACKGROUND: Renal dysfunction is an established predictor of all-cause mortality in intensive care units. This study analyzed the outcomes of coronary care unit (CCU patients and evaluated several biomarkers of acute kidney injury (AKI, including neutrophil gelatinase-associated lipocalin (NGAL, interleukin-18 (IL-18 and cystatin C (CysC on the first day of CCU admission. METHODOLOGY/PRINCIPAL FINDINGS: Serum and urinary samples collected from 150 patients in the coronary care unit of a tertiary care university hospital between September 2009 and August 2010 were tested for NGAL, IL-18 and CysC. Prospective demographic, clinical and laboratory data were evaluated as predictors of survival in this patient group. The most common cause of CCU admission was acute myocardial infarction (80%. According to Acute Kidney Injury Network criteria, 28.7% (43/150 of CCU patients had AKI of varying severity. Cumulative survival rates at 6-month follow-up following hospital discharge differed significantly (p<0.05 between patients with AKI versus those without AKI. For predicting AKI, serum CysC displayed an excellent areas under the receiver operating characteristic curve (AUROC (0.895 ± 0.031, p < 0.001. The overall 180-day survival rate was 88.7% (133/150. Multiple Cox logistic regression hazard analysis revealed that urinary NGAL, serum IL-18, Acute Physiology, Age and Chronic Health Evaluation II (APACHE II and sodium on CCU admission day one were independent risk factors for 6-month mortality. In terms of 6-month mortality, urinary NGAL had the best discriminatory power, the best Youden index, and the highest overall correctness of prediction. CONCLUSIONS: Our data showed that serum CysC has the best discriminative power for predicting AKI in CCU patients. However, urinary NGAL and serum IL-18 are associated with short-term mortality in these critically ill patients.

    During a period of 3 months an infection survey was carried out in 4 intensive care units (ICUs), 2 in Vienna, Austria, and one each in Ulm and Münster, Federal Republic of Germany, using a common protocol. A total of 329 patients was monitored prospectively. This pilot study was performed to evaluate the usefulness of parameters included in the monitoring form. It was attempted to characterize the patient populations of the four units. Mean duration of stay (1-12 days), mortality (8-26%), leading diagnosis upon admission, intubation rate (41-91%) and use of pulmonary artery catheter (12-35%) were distinctly different. The rate of patients admitted already with an infection was 9-43%, septicemia was diagnosed in up to 27% of the diseased. The rate of infection acquired in the unit was between 12 and 37%, the most frequent types were bronchopneumonia, septicemia and urinary tract infection. When septicemia patients were compared to non-septicemia patients who had been admitted for more than 3 days, it appeared that the latter stayed significantly shorter at the ICU and showed less frequently bronchopneumonia or urinary tract infection at the time of admission. Septicemia patients acquired more frequently additional infections like broncho-pneumonia or urinary tract infection while staying at the ICU. The median day of onset of septicemia was the fifth day and only in a quarter of cases diagnosis could be supported by a positive blood culture. The use of antibiotics in the 4 ICUs is compared and shows marked differences. Based upon experience with this type of infection survey a new modified protocol is introduced, which displays the time course of documented events.

    The FTIR and FT Raman spectra of the first generation dendrimers, possessing oxybenzaldehyde (G1) or oxyphenylazobenzaldehyde (G2) terminal groups and sodium 4-[4-oxyphenyl)azo]-benzaldehyde (SOAB) were studied. The structural optimization and normal mode analysis were performed for dendrimer G2 on the basis of the density functional theory (DFT). These calculations gave the frequencies of vibrations, infrared intensities and Raman scattering activities for the E- and Z-forms of azobenzene unit. The energy differences between the E- and Z-forms are 12.62 and 25.16 kcal/mol for SOAB and G2. The calculated in gas phase dipole moments for the E- and Z-forms are equal to 20.86, 18.28 D (SOAB) and 7.56, 8.88 D (G2). The calculated geometrical parameters and harmonic vibrational frequencies are predicted in a good agreement with the experimental data. It was found that dendrimer G2 molecule has a concave lens structure with planar sbnd Osbnd C6H4sbnd CHdbnd Nsbnd N(CH3)Pdbnd S and sbnd Osbnd C6H4sbnd Ndbnd Nsbnd C6H4sbnd CHdbnd O fragments and slightly non-planar cyclotriphosphazene core. The experimental IR and Raman spectra of dendrimer G2 were interpreted by means of potential energy distributions. Relying on DFT calculations a complete vibrational assignment is proposed. The strong band 1598 cm-1 in the IR spectra show marked changes of the optical density in dependence of substituents in the aromatic ring. The differences in the IR and Raman spectra of SOAB and G2 for the E- and Z-forms of azobenzene units were cleared up. During structural isomerization of azobenzene units, redistribution of band intensities appears to a much higher extent than frequency shifts.

    Full Text Available Dogs are the most common animal species kept around households and are also known to be source of diseases of importance to human health. The aim of this study was to determine some characteristics of dog population and husbandry practices that favour the spread of zoonotic parasites in Yaounde, Cameroon. Three hundred and twenty-two households owning at least one dog were recruited into the study. Information on dog and household characteristics as well as potential risk factors for the transmission of dog-related zoonotic parasites was collected using self-administered questionnaires. Over three-quarters of the households (76% owned one dog each while 62% (200/322 kept dogs strictly for security reasons. Eighty four per cent (270/322 of the dogs owned were of local breed type and dominated by male dogs (64%. Twenty five per cent (80/320 of households left their dogs permanently free while 84% (240/320 declared negligence in disposing dog’s faeces. Dogs in 35.5% (114/320 of the households rarely or have never been consulted by a veterinarian. Although 242 (75% respondents were aware of zoonotic diseases, only 51 (21% of these knew parasites from dogs may infect human beings. The provision of a defecation site for dogs and access to living quarters were associated with household head’s level of education and care taker category, respectively. The current dog husbandry practices in Yaounde are likely to favour the spread of dog-related zoonotic diseases. Further investigations to determine the prevalence of zoonotic parasites, educational intervention as well as routine veterinary care are necessary to reduce the risk exposures to zoonotic parasites from dogs.

    Groundwater quality in the 48-square-mile Santa Barbara study unit was investigated in 2011 as part of the California State Water Resources Control Board’s Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project. The study unit is mostly in Santa Barbara County and is in the Transverse and Selected Peninsular Ranges hydrogeologic province. The GAMA Priority Basin Project is carried out by the U.S. Geological Survey in collaboration with the California State Water Resources Control Board and Lawrence Livermore National Laboratory.The GAMA Priority Basin Project was designed to provide a statistically unbiased, spatially distributed assessment of the quality of untreated groundwater in the primary aquifer system of California. The primary aquifer system is defined as that part of the aquifer corresponding to the perforation interval of wells listed in the California Department of Public Health database for the Santa Barbara study unit. This status assessment is intended to characterize the quality of groundwater resources in the primary aquifer system of the Santa Barbara study unit, not the treated drinking water delivered to consumers by water purveyors.The status assessment for the Santa Barbara study unit was based on water-quality and ancillary data collected in 2011 by the U.S. Geological Survey from 23 sites and on water-quality data from the California Department of Public Health database for January 24, 2008–January 23, 2011. The data used for the assessment included volatile organic compounds; pesticides; pharmaceutical compounds; two constituents of special interest, perchlorate and N-nitrosodimethylamine (NDMA); and naturally present inorganic constituents, such as major ions and trace elements. Relative-concentrations (sample concentration divided by the health- or aesthetic-based benchmark concentration) were used to evaluate groundwater quality for those constituents that have federal or California regulatory and non

    2011-01-01

    The increased frequency and severity of large wildfires in the western United States is an important ecological and management issue with direct relevance to amphibian conservation. Although the knowledge of fire effects on amphibians in the region is still limited relative to most other vertebrate species, we reviewed the current literature to determine if there are evident patterns that might be informative for conservation or management strategies. Of the seven studies that compared pre- and post-wildfire data on a variety of metrics, ranging from amphibian occupancy to body condition, two reported positive responses and five detected negative responses by at least one species. Another seven studies used a retrospective approach to compare effects of wildfire on populations: two studies reported positive effects, three reported negative effects from wildfire, and two reported no effects. All four studies that included plethodontid salamanders reported negative effects on populations or individuals; these effects were greater in forests where fire had been suppressed and in areas that burned with high severity. Species that breed in streams are also vulnerable to post-wildfire changes in habitat, especially in the Southwest. Wildfire is also important for maintaining suitable habitat for diverse amphibian communities, although those results may not be evident immediately after an area burns. We expect that wildfire will extirpate few healthy amphibian populations, but it is still unclear how populations will respond to wildfire in the context of land management (including pre- and post-fire timber harvest) and fragmentation. Wildfire may also increase the risk of decline or extirpation for small, isolated, or stressed (e.g., from drought or disease) populations. Improved understanding of how these effects vary according to changes in fire frequency and severity are critical to form more effective conservation strategies for amphibians in the western United States.

    Full Text Available The paper aims at identifying the main competitors and competitive advantages of small scale manufacturers. The manufacturers were selected from four manufacturing industries producing textiles, bicycle and bicycle parts, food products and beverages and leather and leather products in the state of Punjab, India. The data were collected from 200 units out of which 173 units were considered for data analysis purposes. In this study, a number of statements indicating the relevant quality certification, competition and cluster association were developed and the respondents were asked to respond to the statement on a five-point likert scale. The Kruskal-Wallis test was applied to know the significant differences among the respondents with regards to different industries, age, and turnover groups with respect to the impact of cluster association. The test was applied at an assumed p-value =0.05. The statements with less than 0.05 p-value are considered significant and those with p-value more than the assumed p-value are considered to be insignificant. The weighted rankings were also calculated for the purpose of data analysis in respect to competitive advantages by assigning the weights 4, 3, 2 and 1 to ranks 1, 2, 3 and 4 respectively.

    During an outbreak of infections caused by methicillin-resistant (MR) Staphylococcus aureus in our burn unit, we conducted an extensive 10-week study to define the environmental epidemiology of the organism. The inanimate environment in patient rooms and adjacent areas was examined by using volumetric air samplers and Rodac plates. Airborne and surface level contamination with MR S. aureus was quantitated, and overall, MR S. aureus comprised 16, 31, and 40% of all bacterial growth from air, elevated surfaces, and floor surfaces, respectively. Mean air, elevated surface, and floor surface MR S. aureus contamination in rooms of MR S. aureus-infected burn patients were 1.9 MR S. aureus per ft3 (ca. 0.028 m3), 20 MR S. aureus per Rodac plate and 48 MR S. aureus per Rodac plate, respectively. Peak patient room environmental contamination levels were 6.9 MR S. aureus per ft3 of air, 70 MR S. aureus per Rodac plate per elevated surface and 138 MR S. aureus per Rodac plate per floor surface. Environmental contamination levels in the adjacent work areas were considerably lower than in infected patient rooms. There was ample opportunity for contamination of personnel through the inanimate environment in this unit. PMID:6630447

    Yanshan Petrochemical Company after having expanded its 300 kt/a steam cracking unit to 450 kt/a in 1994 is still experiencing such problems as low feedstock flexibility, high energy consumption and smaller scale of ethylene unit. In order to fully improve technical capability of steam crackers, reduce energy consumption, improve feedstock flexibility and increase production capacity, a lot of technical revamp cases on steam cracking were studied and compared. Revamp of relevant facilities has expanded the ethylene capacity to the target of 660 kt/a with the actual capacity reaching 710 kt/a. This revamp project has remarkably reduced the energy consumption, which is capable of using naphtha, light diesel fuel, heavy diesel fuel and the hydrocracked tail oil as the steam cracking feedstock. This project is the first to apply refrigeration by means of a mixed cooling agent and has succeeded in using C3 catalytic rectification/hydrogenation technology, which has given an impetus to the progress of steam cracking industry in the world.

Methods Google Trends data about dabbing and related topics (eg, electronic nicotine delivery system [ENDS], also known as e-cigarettes) in the United States between January 2004 and December 2015 were collected by using relevant search terms such as “dab rig.” The correlation between dabbing (including topics: dab and hash oil) and ENDS (including topics: vaping and e-cigarette) searches, the regional distribution of dabbing searches, and the impact of cannabis legalization policies on geographical location in 2015 were analyzed. Results Searches regarding dabbing increased in the United States over time, with 1,526,280 estimated searches during 2015. Searches for dab and vaping have very similar temporal patterns, where the Pearson correlation coefficient (PCC) is .992 (Poil and e-cigarette, in which the corresponding PCC is .931 (Pcannabis surveillance, and these findings can help enhance the understanding of the popularity of dabbing and provide insights for future research and informed policy making on dabbing.

    Full Text Available The unit commitment (UC problem which is an important subject in power system engineering is solved by using Lagragian relaxation (LR, penalty function (PF, and augmented Lagrangian penalty function (ALPF methods due to their higher solution quality and faster computational time than metaheuristic approaches. This problem is considered to be a nonlinear programming-(NP- hard problem because it is nonlinear, mixed-integer, and nonconvex. These three methods used for solving the problem are based on dual optimization techniques. ALPF method which combines the algorithmic aspects of both LR and PF methods is firstly used for solving the UC problem. These methods are compared to each other based on feasible schedule for each stage, feasible cost, dual cost, duality gap, duration time, and number of iterations. The numerical results show that the ALPF method gives the best duality gap, feasible and dual cost instead of worse duration time and the number of iterations. The four-unit Tuncbilek thermal plant which is located in Kutahya region in Turkey is chosen as a test system in this study. The programs used for all the analyses are coded and implemented using general algebraic modeling system (GAMS.

    The purpose of this Phase I/II feasibility study is to assemble and screen a list of alternatives for remediation of the 300-FF-5 operable site on the Hanford Reservation. This screening is based on information gathered in the Phase I Remedial Investigation (RI) and on currently available information on remediation technologies. The alternatives remaining after screening provide a range of response actions for remediation. In addition, key data needs are identified for collection during a Phase II RI (if necessary). This Phase I/II FS represents a primary document as defined by the Tri-Party Agreement, but will be followed by a Phase III FS that will further develop the alternatives and provide a detailed evaluation of them. The following remedial action objectives were identified for the 300-FF-5 operable unit: Limit current human exposure to contaminated groundwater in the unit; Limit discharge of contaminated groundwater to the Columbia River; Reduce contaminant concentrations in groundwater below acceptable levels by the year 2018.

    Full Text Available Background. China is the largest producer of rape oilseed in the world; however, the mechanization level of rape harvest is relatively low, because rape materials easily adhere to the cleaning screens of combine harvesters, resulting in significant cleaning losses. Previous studies have shown that bionic nonsmooth surface cleaning screens restrain the adhesion of rape materials, but the underlying mechanisms remain unclear. Objective. The reciprocating friction between rape stalk and bionic nonsmooth metal surface was examined. Methods. The short-time Fourier transform method was used to discriminate the stable phase of friction signals and the stick-lag distance was defined to analyze the stable reciprocating friction in a phase diagram. Results. The reciprocating friction between rape stalk and metal surface is a typical stick-slip friction, and the bionic nonsmooth metal surfaces with concave or convex units reduced friction force with increasing reciprocating frequency. The results also showed that the stick-lag distance of convex surface increased with reciprocating frequency, which indicated that convex surface reduces friction force more efficiently. Conclusions. We suggest that bionic nonsmooth surface cleaning screens, especially with convex units, restrain the adhesion of rape materials more efficiently compared to the smooth surface cleaning screens.

    Sexual antagonism and meiotic drive are sex-specific evolutionary forces with the potential to shape genomic architecture. Previous theory has found that pairing two sexually antagonistic loci or combining sexual antagonism with meiotic drive at linked autosomal loci augments genetic variation, produces stable linkage disequilibrium (LD) and favours reduced recombination. However, the influence of these two forces has not been examined on the X chromosome, which is thought to be enriched for sexual antagonism and meiotic drive. We investigate the evolution of the X chromosome under both sexual antagonism and meiotic drive with two models: in one, both loci experience sexual antagonism; in the other, we pair a meiotic drive locus with a sexually antagonistic locus. We find that LD arises between the two loci in both models, even when the two loci freely recombine in females and that driving haplotypes will be enriched for male-beneficial alleles, further skewing sex ratios in these populations. We introduce a new measure of LD, Dz', which accounts for population allele frequencies and is appropriate for instances where these are sex specific. Both models demonstrate that natural selection favours modifiers that reduce the recombination rate. These results inform observed patterns of congealment found on driving X chromosomes and have implications for patterns of natural variation and the evolution of recombination rates on the X chromosome.

    Full Text Available Abstract Recent publications put a serious warning regarding the inefficacy of sulphadoxine-pyrimethamine (SP for the intermittent preventive treatment of malaria in young children (IPTi. Recommendations for other therapies are being made. By using a different and better sulphonamide (sulphamethoxypyrazine, it is possible to manufacture fixed dose combination pills with artesunate and pyrimethamine. This combination permits a full therapy over 24 hours (dosing interval being 12 hours. It is recommended that this combination should be tested in future field studies of IPTi.

This study is a review of the gastrointestinal function of patients in critical care, with the aim to assess the feasibility and effectiveness of grading criteria developed by the European Society of Intensive Care Medicine (ESICM Working Group on Abdominal Problems (WGAP. Methods: Data of patients who were admitted to the ICU of Shenzhen People’s Hospital, Shenzhen, People’s Republic of China, from January 2010 to December 2011 were reviewed. A total of 874 patients were included into the current study. Their sex, age, ICU admissive causes, complication of diabetes, AGI grade, primary or secondary AGI, mechanical ventilation (MV, and length of ICU stay (days were recorded as risk factors of death. These risk factors were studied by unconditioned logistic regression analysis. Results: All the risk factors affected mortality rate. Unconditional logistic regression analysis revealed that the mortality rate of secondary AGI was 71 times higher than primary AGI (odds ratio [OR] 4.335, 95% CI [1.652, 11.375]. When the age increased by one year, the mortality probability would increase fourfold. Mortality in patients with MV was 63-fold higher than for patients with non-MV. Mortality rate increased 0.978 times with each additional day of ICU stay. Conclusion: Secondary AGI caused by severe systemic conditions can result in worsened clinical outcomes. The 2012 ESICM WGAP AGI recommendations were to some extent feasible and effective in guiding clinical practices, but the grading system lacked the support of objective laboratory outcomes.

Yet, cultural differences between South Korea and the United States exist. The purpose ofthis study was to identify and characterize potential cultural differences in the Korean and US institutional review board (IRB approach to certain topics.Methods: A qualitative analysis of a 9-item survey, describing 4 research study case scenarios, sent to IRB members from the United States and South Korea. The case scenarios involved the followingissues: (1 the need for consent for retrospective chart review when research subjects receive their care after the study is conceived; (2 child assent; (3 individual versus population benefit; and (4 exception from informed consent in emergency resuscitation research. The free-text responses were analyzed and abstracted for recurrent themes.Results: Twenty-three of the 45 survey recipients completed the survey, for an overall response rate of 51%. The themes that emerged were as follows: (1 the importance of parental authority among Korean participants versus the importance of child autonomy and child assent among US participants; (2 the recognition of the rights of a proxy or surrogate who can represent an individual’s values by all participants; and (3 the importance of the community, expressed by the Korean respondents, versus individualism, expressed by US respondents.Conclusion: Whereas US participants appear to emphasize the importance of the individual and the autonomy of a child, the Korean respondents stressed the importance of parental authority andbenefiting the community, above and beyond that of the individual person. However, there was substantial overlap in the themes expressed by respondents from both countries.

    Full Text Available Animals can use their environments more efficiently by selecting particular sources of information (personal or social, according to specific situations. Group-living animals may benefit from gaining information based on the behaviour of other individuals. Indeed, social information is assumed to be faster and less costly to use than personal information, thus increasing foraging efficiency. However, when food sources change seasonally or are randomly distributed, individual information may become more reliable than social information. The aim of this study was to test the use of conflicting personal versus social information in goats (Capra hircus, in a foraging task. We found that goats relied more on personal than social information, when both types of information were available and in conflict. No effect of social rank was found on the occasions when goats followed other demonstrator goats. Goats are selective browsers/grazers and therefore relying on personal rather than social information could be the most efficient way to find patchily distributed resources in highly variable environments. Studies testing specific assumptions regarding the use of different sources of information can extend our understanding of decision making, including observed patterns of social learning.

    This work was focused on the study of the biodegradation processes jeopardizing a mural painting conserved in the basement of Ariadne House (archaeological site of Pompeii, Italy). The fresco stood out for its peculiar state of preservation: the upper part, recovered in 1988, was just barely colonized by microorganisms. On the contrary, the lower part (excavated in 2005) was almost completely covered by extensive biological patinas. The genomic characterization carried out by polymerase chain reaction (PCR) highlighted the presence of seven different fungi strains on the mural surface. Beside, in situ and laboratory analyses were performed with the purpose of identifying the causes of the heterogeneous spatial distribution of the biopatinas. The in situ Raman spectroscopy and energy dispersive X-ray fluorescence (ED-XRF) spectroscopy measurements excluded any link between the heterogeneous colonization and the original materials present in the wall. On the other side, X-ray diffraction (XRD) and scanning electron microscopy (SEM) on microsamples proved the presence of a thin volcanic material layer overlying the lower part of the fresco. Considering that most of the biofilms of the studied mural painting only growth over these residues, it was confirmed the role of volcanic material as a suitable support for biological colonization. Thanks to the obtained results, this research helped to understand more in depth an important degradation pathway threatening the artworks from one of the most important archaeological sites in the world.

    Cardiovascular disease, preceded by vascular endothelial dysfunction, is a prominent cause of death in dogs. L-carnitine and taurine, well known for their antioxidative capacity, beneficially affect cardiovascular disease as well as certain dog cardiomyopathies. It is well established that vascular endothelial dysfunction precedes cardiovascular disease and that "vasoprotective factors" (NO and antioxidants) prevent apoptosis, whereas "risk factors" such as oxidized LDL, hyperglycemia, and free fatty acids trigger it in cultured human vascular endothelial cells. Whereas human vascular cell in vitro models are widely established and used for the characterisation of potential vasoprotective substances, such models are not available for canine endothelial cells. In the present study we therefore developed an in vitro model, which allows the testing of the effects of different substances on proliferation and apoptosis in canine aortic endothelial cells. This model was used to test L-carnitine, taurine, pomegranate extract, and Soy Isoflavones in comparison to reference substances (glutathione and pioglitazone) previously shown to modulate human endothelial cell function. L-carnitine and taurine neither exhibited antiproliferative nor antiapoptotic activities in the context of this study. However extracts from pomegranate and soy isoflavones dramatically reduced proliferation and apoptosis in a dose dependent fashion, being in line with a vasoprotective activity in dogs.

    In Chapter 1 the differences in the climate change policy positions of Germany, the United Kingdom and the United States, are discussed against the background of a brief introduction in the scientific and international political aspects of climate change. Chapter 2 will present the theoretical framework of the study, starting with an overview of basic approaches in International Relations (IR) and their usefulness for the analysis of international environmental politics. Subsequently, some relevant IR and non-IR theories will be discussed in detail, distinguishing into state-oriented approaches (realism, regime analysis); multiple level approaches (two-level games; environmental interest profiles); and transnational approaches (Regulation School, Amsterdam School, Cultural Analysis, and Centre for Contemporary Cultural Studies (CCCS)). It is concluded that an interest-oriented approach (focusing on `objective` interests) and a perception-oriented approach (focusing on environmental views) need to be combined to explain international environmental politics. In chapter 3 this theoretical framework is made operational and a methodology for the research is presented. Chapters 4 and 5 deal with the interest-oriented approach, explaining the climate change policy positions of Germany, the United Kingdom and the United States in terms of `objective` interests. More specifically, in chapter 4 present constellations of climate change interests in these countries will be compared. Next, since climate change is a long term issue, chapter 5 focuses on structural change that will shape future climate change interests. It is expected that present nor future `objective` interests will offer an adequate explanation for the observed differences in climate change policy positions. In the Chapters 6 and 7 the perception-oriented approach is presented, explaining the differences in climate change policy positions of Germany, the United Kingdom and the United States in terms of cross

    Full Text Available Abstract Background Autism Spectrum Conditions (ASCs are characterized by a high degree of clinical heterogeneity, but the extent to which this variation represents a severity gradient versus discrete phenotypes is unclear. This issue has complicated genetic studies seeking to investigate the genetic basis of the high hereditability observed clinically in those with an ASC. The aim of this study was to examine the possible clustering of symptoms associated with ASCs to determine whether the observed distribution of symptom type and severity supported either a severity or a symptom subgroup model to account for the phenotypic variation observed within the ASCs. Methods We investigated the responses of a group of adults with higher functioning ASCs on the fifty clinical features examined in the Autism Spectrum Quotient, a screening questionnaire used in the diagnosis of higher functioning ASCs. In contrast to previous studies we have used this instrument with no a priori assumptions about any underlying factor structure of constituent items. The responses obtained were analyzed using complete linkage hierarchical cluster analysis. For the members of each cluster identified the mean score on each Autism Spectrum Quotient question was calculated. Results Autism Spectrum Quotient responses from a total of 333 individuals between the ages of 16.6 and 78.0 years were entered into the hierarchical cluster analysis. The four cluster solution was the one that generated the largest number of clusters that did not also include very small cluster sizes, defined as a membership comprising 10 individuals or fewer. Examination of these clusters demonstrated that they varied in total Autism Spectrum Quotient but that the profiles across the symptoms comprising the Autism Spectrum Quotient did not differ independently of this severity factor. Conclusion These results are consistent with a unitary spectrum model, suggesting that the clinical heterogeneity observed

    Aspergillus spp. invasive external otitis (IEO) is a rare infection. We performed a seven-year, single-centre retrospective study from 2007 to 2014 including all patients with proven Aspergillus spp. IEO. Twelve patients were identified. All patients had a poorly controlled diabetes mellitus and one underwent solid organ transplant. The most frequently isolated species was Aspergillus flavus (n = 10) and voriconazole was the first-line therapy in all cases, with a median length of treatment of 338.5 days (158-804 days). None of the patients underwent extensive surgery. The clinical outcome was excellent. However, otological sequelae were reported, including hearing impairment (n = 7) and facial palsy (n = 3).

    The Darwinian paradox of male homosexuality in humans is examined, i.e. if male homosexuality has a genetic component and homosexuals reproduce less than heterosexuals, then why is this trait maintained in the population? In a sample of 98 homosexual and 100 heterosexual men and their relatives (a total of over 4600 individuals), we found that female maternal relatives of homosexuals have higher fecundity than female maternal relatives of heterosexuals and that this difference is not found in female paternal relatives. The study confirms previous reports, in particular that homosexuals have more maternal than paternal male homosexual relatives, that homosexual males are more often later-born than first-born and that they have more older brothers than older sisters. We discuss the findings and their implications for current research on male homosexuality.

    Prehospital postresuscitation induced hypothermia (IH) has been shown to reduce neurological complications in comatose cardiac-arrest survivors. Retrofitting ambulances to include equipment appropriate to initiate hypothermia, such as refrigeration units for cooled saline, is expensive. The objective of this nonhuman subject research study was to determine if inexpensive, commercially available coolers could, in conjunction with five reusable ice packs, keep two 1 L bags of precooled 0.9% normal saline solution (NSS) at or below 4°C for an average shift of eight to 12 hours in a real-world environment, on board in-service Emergency Medical Service (EMS) units, over varying weather conditions in all seasons. The coolers were chosen based on availability and affordability from two nationally available brands: The Igloo MaxxCold (Igloo Products Corp., Katy, Texas USA) and Coleman (The Coleman Company, Wichita, Kansas USA). Both are 8.5 liter (nine-quart) coolers that were chosen because they adequately held two 1 L bags of saline solution, along with the reusable ice packs designated in the study design, and were small enough for ease of placement on ambulances. Initial testing of the coolers was conducted in a controlled environment. Thereafter, each EMS unit was responsible to cool the saline to less than 4°C prior to shift. Data were collected by emergency medical technicians, paramedics, and resident physicians working in seven different ambulance squads. Data analysis was performed using repeated measurements recorded over a 12-hour period from 19 individual coolers and were summarized by individual time points using descriptive statistics. Initial testing determined that the coolers maintained temperatures of 4°C for 12 hours in a controlled environment. On the ambulances, results based on the repeated measurements over time revealed that the saline solution samples as defined in the protocol, remained consistently below 4°C for 12 hours. Utilizing the lower

    The world's energy demand is increasing with the development of human civilization. Due to limited energy resource, after 2020 fossil fuels thus is predicted will be replaced by renewable resources. Taking an example, one of the potential renewable energy to be considered is biogas, as its high content of methane, which can be produced via the fermentation process of the organic compounds under controlled anaerobic environment by utilizing the methanogen bacteria. However, prior the further use, this biogas must be purified from its impurities contents, i.e. acid gas of CO2 and H2S, up to 4% and 16 ppmv, respectively, in the acid gas removal unit. This such of purification efforts, will significantly increase the higher heating value of biogas, approximately from 600 to 900 Btu/Scf. During the purification process in this acid gas removal unit, NaOH solution is used as a liquid absorbent to reduce those acid gases content, in which the by-product of alkali salt (brine) was produced as waste. Here we report the feasibility study of the NaOH regeneration process in acid gas removal unit via membrane electrolysis technology, in which both the technical and economic aspects are taken account. To be precise in procedure, the anode semi-cell was filled with the brine solution, while the cathode semi-cell was filled with demineralized water, and those electrodes were separated by the cation exchange membrane. Furthermore, the applied potential was varied ranging from 5, 10, 15 and to 20 V, while the concentration of KCl electrolyte solutions were varied ranging from 0.01, 0.05, 0.1, and to 0.03 M. This study was conducted under controlled temperatures of 30 and 50 °C. Here we found that the % sodium recovery was increased along with the applied potential, temperature, and the decrease in KCl electrolyte concentration. We found that the best results, by means of the highest % sodium recovery, i.e. 97.26 %, was achieved under the experimental condition of temperature at 30

    In five neonatal intensive care units (NICUs) in two cities, the hand hygiene applications of 72 nurses included in this observational study have been investigated. The research was conducted between February and June 2007. It was found that before entering the NICUs, majority of nurses have washed their hands but used much less alcohol-based antiseptics; more than half of the nurses did not use gloves, and 50 of them did not wash their hands before care and one-third of the nurses did not wash their hands after care after neonatal treatments. The results obtained from our research showed that most of the nurses paid more attention to hand washing before applying medical treatment.

    Full Text Available Highly interruptive clinical environments may cause work stress and suboptimal clinical care. This study features an intervention to reduce workflow interruptions by re-designing work and organizational practices in hospital physicians providing ward coverage. A prospective, controlled intervention was conducted in two surgical and two internal wards. The intervention was based on physician quality circles - a participative technique to involve employees in the development of solutions to overcome work-related stressors. Outcome measures were the frequency of observed workflow interruptions. Workflow interruptions by fellow physicians and nursing staff were significantly lower after the intervention. However, a similar decrease was also observed in control units. Additional interviews to explore process-related factors suggested that there might have been spill-over effects in the sense that solutions were not strictly confined to the intervention group. Recommendations for further research on the effectiveness and consequences of such interventions for professional communication and patient safety are discussed.

  1. Studying the incommensurability that unites us: persuasion across discourse communities, persuasion via boundary objects

    In the science studies literature the theoretical construct of boundary objects has been developed to explain how diverse communities clustered around a scientific subject area cooperate to advance that area. Boundary objects are 'scientific objects that inhabit several intersecting social worlds . . . and satisfy the informational requirements of each of them' (Star and Griesemer 393). Star and Griesemer's foundational article showed that these objects can be shared by communities ranging from academic researchers to amateur enthiasts, adminsitrators, philanthropists, and technicians. While each community understands the object differently, there is enough commonality in the understanding of the object to unite these distinct social worlds and facilitate cooperation among them.

    Burnout is a work stress syndrome caused by a prolonged contact with users which present physical and emotional suffering. C. Maslach, one of the main authors, refers that this syndrome is characterized by emotional exhaustion, depersonalization and reduced personal skills. However, the researches done within the Nephrology and Dialysis Departments on this phenomenon are still few in the literature, despite the peculiar characteristics of the care relationship that develops between caregivers and patients on dialysis treatment. The present study aims to highlight the importance of assessing the levels of burnout and strategies of adaptation to stress (coping) in healthcare workers of Nephrology and Dialysis Unit, so that their psychological well-being could be preserved, preventing the possibility of a progressive deterioration of the care relationship with the patient. The implementation of psychological training courses for healthcare workers seems to be a useful tool aimed at the prevention and management of the burnout syndrome.

    Potential sanitary effects related to electromagnetic fields exposure raise public concerns, especially for fetuses during pregnancy. Human fetus exposure can only be assessed through simulated dosimetry studies, performed on anthropomorphic models of pregnant women. In this paper, we propose a new methodology to generate a set of detailed utero-fetal unit (UFU) 3D models during the first and third trimesters of pregnancy, based on segmented 3D ultrasound and MRI data. UFU models are built using recent geometry processing methods derived from mesh-based computer graphics techniques and embedded in a synthetic woman body. Nine pregnant woman models have been generated using this approach and validated by obstetricians, for anatomical accuracy and representativeness.

    Darajat unit III geothermal power plant is developed by PT. Chevron Geothermal Indonesia (CGI). The plant capacity is 121 MW and load 110%. The greatest utilization power is consumed by Hot Well Pump (HWP) and Cooling Tower Fan (CTF). Reducing the utility power can be attempted by utilizing the wet bulb temperature fluctuation. In this study, a modelling process is developed by using Engineering Equation Solver (EES) software version 9.430.The possibility of energy saving is indicated by Specific Steam Consumption (SSC) net in relation to wet bulb temperature fluctuation from 9°C up to 20.5°C. Result shows that the existing daily operation reaches its optimum condition. The installation of Variable Frequency Drive (VFD) could be applied to optimize both utility power of HWP and CTF. The highest gain is obtained by VFD HWP installation as much as 0.80% when wet bulb temperature 18.5 °C.

    Federal agencies are mandated to purchase alternative fuel vehicles, increase consumption of alternative fuels, and reduce petroleum consumption. Available plug-in electric vehicles (PEVs) provide an attractive option in the selection of alternative fuel vehicles. PEVs, which consist of both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), have significant advantages over internal combustion engine (ICE) vehicles in terms of energy efficiency, reduced petroleum consumption, and reduced production of greenhouse gas (GHG) emissions, and they provide performance benefits with quieter, smoother operation. This study intended to evaluate the extent to which the United States Coast Guard Headquarters (USCG HQ) could convert part or all of their fleet of vehicles from petroleum-fueled vehicles to PEVs.

    Full Text Available Anaerobic digestion technology is available for converting livestock waste to bio-energy, but its potential is far from fully exploited in the United States because the technology has a scale effect. Utilization of the centralized anaerobic digester (CAD concept could make the technology economically feasible for smaller dairy farms. An interdisciplinary methodology to determine the cost minimizing location, size, and number of CAD facilities in a rural dairy region with mostly small farms is described. This study employs land suitability analysis, operations research model and Geographical Information System (GIS tools to evaluate the environmental, social, and economic constraints in selecting appropriate sites for CADs in Windham County, Connecticut. Results indicate that overall costs are lower if the CADs are of larger size and are smaller in number.

    Although off-road motorcycling is one of the most popular sports activities practised by millions of people worldwide, little has been written on motocross injuries and their prevention. In the UK alone, motocross has grown into a phenomenally ambitious and popular franchise. There are >200 motocross clubs across the country holding >900 events annually. The aim of this study is to categorise and quantify the magnitude of motocross paediatric injuries and associated morbidity. Data were collected prospectively over 4 years (2010-2014) at our unit. All injuries caused by motocross biking that were referred to our trauma and orthopaedic department were included in this study, regardless of whether the rider was performing the sport competitively or recreationally. During the study period, 130 patients (aged 4-17 years) were identified with a total of 142 injuries, ranging from one to six injuries per patient. Most of the injuries were sustained within the early spring and summer months, representing the start of the motocross season; 76 patients required hospital admission, with 60 (42 %) requiring surgical intervention. We present the first epidemiological study of motocross paediatric injuries in the UK. The results from this study highlight the frequency and severity of motocross-related injuries in the paediatric population in the UK. This may assist in providing recommendations and guidelines to governing bodies and to parents. The injuries sustained during motocross have significant resource implications, especially for smaller rural hospitals, as shown by the number of injuries doubling over the past 4 years.

    Aim: To assess the magnetic resonance imaging (MRI) features and natural history of intramedullary tumours in patients with neurofibromatosis type 2 (NF2). Materials and methods: Eleven NF2 patients with intramedullary spinal cord tumours were identified from the database of the multidisciplinary NF2 clinic. All the imaging studies of these patients were individually reviewed by two neuroradiologists to evaluate the size, number, location, imaging characteristics, and interval growth of the intramedullary tumours. Results: Two of the 11 patients had lesions that required surgery. Both these lesions were in the cervical region, and extended over three and five segments respectively. Nine patients with a mean imaging follow-up period of 77 months had lesions that remained stable, apart from the development of small peritumoral cysts in three. The lesions were well circumscribed, often multiple, usually less than 1 cm in diameter, and were most frequently found in the cervical cord. Conclusion: The majority of intramedullary tumours in NF2 patients are very slow growing and share certain MRI features that differ from those of progressive or symptomatic lesions.

    We report 4 pyridoxine-dependent epilepsy patients in which good outcome was determined in three. The 4 patients were male and aged from 7 to 24 years old (from three unrelated Caucasian families). A clinical diagnosis of neonatal pyridoxine-dependent epilepsy was confirmed by biochemical and genetic studies. Clinical evaluation was performed and medical records were reviewed for therapy implementation and management, neurodevelopment outcome, magnetic resonance imaging, and electroencephalography. All were taking pyridoxine treatment and were seizure-free. Elevated urinary alpha-aminoadipic semialdehyde excretion was found in all patients. Antiquitin gene analysis identified a large homozygous deletion in one patient and two heterozygous mutations in the others. Treatment with pyridoxine should be attempted for all cases of infantile and childhood refractory epilepsy, as has been the case over the last 20 years. Currently, urinary alpha-aminoadipic semialdehyde is a reliable biomarker of pyridoxine-dependent epilepsy, even under pyridoxine treatment. Detection of mutations in the antiquitin gene, encoding alpha-aminoadipic semialdehyde dehydrogenase, establishes the diagnosis and allows for adequate genetic counselling.

    Given the growing importance of the health care sector and the significant development of trade in health services, foreign direct investment (FDI) in this sector has gathered momentum with the General Agreement on Trade in Services. Despite extensive case based research and publications in recent years on health care markets and the rise of private sectors, it is surprisingly difficult to find evidence on the relative importance of the largest multinational corporations (MNCs) operating in the health care sector. The objective of the paper is to identify some of the determinants of foreign investment of the largest MNCs operating in this industry. The list of the largest MNCs has been compiled using company websites and data is available for 41 developing economies for which at least two MNCs have an office (branch and/or affiliate). The results of this study have some important implications. They indicate that location-specific advantages of host countries, including good governance, do provide an explication of the internationalization of firms in some developing countries rather than others.

    Full Text Available Aim: To evaluate stereoacuity in patients with acquired esotropia and determine the factors associated with favorable outcomes. Materials and Methods: A total of 68 subjects aged 6 years and above were included in the study. Thorough clinical evaluation including binocular status examination using the Bagolini-striated glass test, The Netherland Organization (TNO, and Randot stereo test were done. The subjects were divided into two groups 1 and 2, based on the amount of deviation. Statistical analysis of the result was performed. Result: The duration of misalignment in the group with deviation less than or equal to 8 prism diopters (PD was 1.49 ± 0.86 years, whereas in the group with deviation more than or equal to 10 PD was 4.64 ± 2.99 years (P = 0.000. Among the subjects in group 1, 89.5% achieved fusion and 52.6% had stereoacuity on both TNO and Randot, whereas in group 2 40% achieved fusion and 3.3% stereopsis on both TNO and Randot (one case with only coarse stereopsis. A subanalysis within group 1 revealed a statistically significant difference for the duration of misalignment (P = 0.02, but a marginal difference for the amount of deviation (P = 0.3. Conclusion: A horizontal deviation up to 8 PD was compatible with stereopsis. Also, the duration of constant misalignment affects the attainment of stereopsis despite successful realignment.

  12. Hidden epistastic interactions can favour the evolution of sex and recombination.

    Directory of Open Access Journals (Sweden)

    Joel R Peck

    Full Text Available Deleterious mutations can have a strong influence on the outcome of evolution. The nature of this influence depends on how mutations combine together to affect fitness. "Negative epistasis" occurs when a new deleterious mutation causes the greatest loss in fitness in a genome that already contains many deleterious mutations. Negative epistasis is a key ingredient for some of the leading hypotheses regarding the evolution of recombination, the evolution of sex, and a variety of other phenomena. In general, laboratory studies have not supported the idea that negative epistasis is ubiquitous, and this has led to doubts about its importance in biological evolution. Here, we show that these experimental results may be misleading, because negative epistasis can produce evolutionary advantages for sex and recombination while simultaneously being almost impossible to detect using current experimental methods. Under asexual reproduction, such hidden epistasis influences evolutionary outcomes only if the fittest individuals are present in substantial numbers, while also forming a very small proportion of the population as a whole. This implies that our results for asexuals will apply only for very large populations, and also limits the extent of the fitness benefits that hidden epistasis can provide. Despite these caveats, our results show that the fitness consequences of sex and recombination cannot always be inferred from observable epistasis alone.

  13. Fortune favours the brave: Movement responses shape demographic dynamics in strongly competing populations.

    Animal movement is a key mechanism for shaping population dynamics. The effect of interactions between competing animals on a population's survival has been studied for many decades. However, interactions also affect an animal's subsequent movement decisions. Despite this, the indirect effect of these decisions on animal survival is much less well-understood. Here, we incorporate movement responses to foreign animals into a model of two competing populations, where inter-specific competition is greater than intra-specific competition. When movement is diffusive, the travelling wave moves from the stronger population to the weaker. However, by incorporating behaviourally induced directed movement towards the stronger population, the weaker one can slow the travelling wave down, even reversing its direction. Hence movement responses can switch the predictions of traditional mechanistic models. Furthermore, when environmental heterogeneity is combined with aggressive movement strategies, it is possible for spatially segregated co-existence to emerge. In this situation, the spatial patterns of the competing populations have the unusual feature that they are slightly out-of-phase with the environmental patterns. Finally, incorporating dynamic movement responses can also enable stable co-existence in a homogeneous environment, giving a new mechanism for spatially segregated co-existence.

    The blue mould decay of apples is caused by Penicillium expansum and is associated with contamination by patulin, a worldwide regulated mycotoxin. Recently, a cluster of 15 genes (patA-patO) involved in patulin biosynthesis was identified in P. expansum. blast analysis revealed that patL encodes a Cys6 zinc finger regulatory factor. The deletion of patL caused a drastic decrease in the expression of all pat genes, leading to an absence of patulin production. Pathogenicity studies performed on 13 apple varieties indicated that the PeΔpatL strain could still infect apples, but the intensity of symptoms was weaker compared with the wild-type strain. A lower growth rate was observed in the PeΔpatL strain when this strain was grown on nine of the 13 apple varieties tested. In the complemented PeΔpatL:patL strain, the ability to grow normally in apple and the production of patulin were restored. Our results clearly demonstrate that patulin is not indispensable in the initiation of the disease, but acts as a cultivar-dependent aggressiveness factor for P. expansum. This conclusion was strengthened by the fact that the addition of patulin to apple infected by the PeΔpatL mutant restored the normal fungal colonization in apple.

    Selection of suitable genotypes from diverse seed banks may help phytoplankton populations to cope with environmental changes. This study examines whether the high genotypic diversity found in the Baltic cyst pool of the toxic dinoflagellate Alexandrium ostenfeldii is coupled to phenotypic variability that could aid short-term adaptation. Growth rates, cellular toxicities and bioluminescence of 34 genetically different clones isolated from cyst beds of four Baltic bloom sites were determined in batch culture experiments along temperature and salinity gradients covering present and future conditions in the Baltic Sea. For all parameters a significant effect of genotype on the response to temperature and salinity changes was identified. General or site-specific effects of the two factors remained minor. Clones thriving at future conditions were different from the best performing at present conditions, suggesting that genotypic shifts may be expected in the future. Increased proportions of highly potent saxitoxin were observed as a plastic response to temperature increase, indicating a potential for higher toxicity of future blooms. The observed standing variation in Baltic seed banks of A. ostenfeldii suggests that the population is likely to persist under environmental change.

    Full Text Available Managing workplace diversity has become a priority concern among organizations in the United Arab Emirates (UAE today. The UAE has one of the world's largest net migration rates, and the number of workers from India, the Philippines, Indonesia, Australia, the USA, among other countries, has increased significantly in recent decades (Burns, 2005. The UAE's cross-border mobility has resulted in the interaction of people with diverse language, customs and ethnic backgrounds. Although diversity has been shown to have a number of benefits, including enhanced employee creativity and competence, this recognition is often found more in theory than actual practice. Diversity can also lead to miscommunication, dysfunctional adaptation behaviors and the creation of barriers that reduce the benefits diversity can bring to the organization. Due to the nature of the UAE workplace, which is dominated by a foreign workforce, this study critically analyzes the benefits and challenges organizations face in the diverse workplaces of the United Arab Emirates. The study used a multi-method approach combining survey data from 450 surveys of foreign workers with qualitative data from interviews with native officials of organizations. It is an attempt to compare the views of UAE workplace experience from two different groups—non-native workers and native officials. The research found a generally favorable view toward workplace diversity from the perspective of surveyed employees. However, when asked more detailed questions about company policy, a significant segment of respondents expressed reservations about their employer’s ability to implement successful intercultural communication and diversity practices.

Fluoride is a primary preventive for caries. While water fluoridation is a major and effective public health means for delivering fluoride on a mass scale, it does not reach many rural areas or population groups such as Latinos who eschew drinking water from municipal sources. This study examines the acceptability to such groups of salt fluoridation, an alternate means of delivering fluoride long used on a global scale.

    Brewster, H; Yeboah, D

    1994-04-01

    This paper opens by expressing disappointment in the disparities between published estimations of the effectiveness of foreign aid to developing countries and effectiveness data which arise from the application of complex econometric methods. The new dilemmas for aid policy include the fact that aid increasingly devoted to human development at the expense of productive activity is unlikely to create the material development which will allow maintenance of human development targets. The second part of the paper presents comparative statistics on gross national product, official development assistance, and savings growth which paint a disturbing picture because the growth of domestic savings has been negative in the period 1967-87 in nine of the 11 less developed countries with data available. Section 3 covers the shortcomings of econometric experiments which neither confirm nor deny the findings of other studies on the effectiveness of aid. The fourth section describes constraints to the growth of income imposed by the foreign exchange, the rate of return on investment, and the growth of labor productivity and presents statistical evidence supporting aid policy which would 1) take advantage of opportunities to rehabilitate output growth in traditional industries without the addition of a great deal of capital, 2) direct attention to increasing the absolute gross national product (GNP) to raise the growth of per capital income, and 3) strategically reorient the structure of aid to increase the absolute GNP faster to accelerate reversal of the negative savings pattern and speed the reduction of fertility. Section 5 considers suggested shifts in aid policy orientation dealing with 1) population growth, income level, and food security; 2) reconstruction and structural adjustment; 3) rationalizing aid for social, institutional, and human development and technical assistance. The concluding section notes that the suggested strategic reorientation of the structure of aid

    Abstract Social accountability is increasingly invoked as a way of improving health services. This article presents a theory-driven qualitative study of the context, mechanisms and outcomes of a social accountability program, Citizen Voice and Action (CVA), implemented by World Vision (WV) in Zambia. Primary data were collected between November 2013 and January 2014. It included in-depth interviews and focus group discussions with program stakeholders. Secondary data were used iteratively—to inform the process for primary data collection, to guide primary data analysis and to contextualize findings from the primary data. CVA positively impacted the state, society, state–society relations and development coordination at the local level. Specifically, sustained improvements in some aspects of health system responsiveness, empowered citizens, the improved provision of public goods (health services) and increased consensus on development issues appeared to flow from CVA. The central challenge described by interviewees and FGD participants was the inability of CVA to address problems that required central level input. The mechanisms that generated these outcomes included productive state–society communication, enhanced trust, and state–society co-production of priorities and the provision of services. These mechanisms were activated in the context of existing structures for state–society interaction, willing political leaders, buy-in by traditional leaders, and WV’s strong reputation and access to resources. Prospective observational research in multiple contexts would shed more light on the context, mechanisms and outcomes of CVA programs. In addition to findings that are intuitive and well supported in the literature we identified new areas that are promising areas for future research. These include (1) the context of organizational reputation by the organization(s) spearheading social accountability efforts; (2) the potential relationship between social

    Circulating adiponectin (APN) is an immunomodulatory, pro-angiogenic, and anti-apoptotic adipocytokine protecting against acute viral heart disease and preventing pathological remodelling after cardiac injury. The purpose of this study was to describe the regulation and effects of APN in patients with inflammatory cardiomyopathy (DCMi). Adiponectin expression and outcome were assessed in 173 patients with DCMi, 30 patients with non-inflammatory DCM, and 30 controls. Mechanistic background of these findings was addressed in murine experimental autoimmune myocarditis (EAM), a model of human DCMi, and further elucidated in vitro. Adiponectin plasma concentrations were significantly higher in DCMi compared with DCM or controls, i.e. 6.8 ± 3.9 µg/mL vs. 5.4 ± 3.6 vs. 4.76 ± 2.5 µg/mL (P< 0.05, respectively) and correlated significantly with cardiac mononuclear infiltrates (CD3+: r(2)= 0.025, P= 0.038; CD45R0+: r(2)= 0.058, P= 0.018). At follow-up, DCMi patients with high APN levels showed significantly increased left ventricular ejection fraction improvement, decreased left ventricular end-diastolic diameter, and reduced cardiac inflammatory infiltrates compared with patients with low APN levels. A multivariate linear regression analysis implicated APN as an independent prognostic factor for inhibition of cardiac inflammation. In accordance with these findings in human DCMi, EAM mice exhibited elevated plasma APN. Adiponectin gene transfer led to significant downregulation of key inflammatory mediators promoting disease. Mechanistically, APN acted as a negative regulator of T cells by reducing antigen specific expansion (P< 0.01) and suppressed TNFα-mediated NFκB activation (P< 0.01) as well as release of reactive oxygen species in cardiomyocytes. Our results implicate that APN acts as endogenously upregulated anti-inflammatory cytokine confining cardiac inflammation and progression in DCMi.

    Full Text Available This paper reports on research based on an experimental questionnaire designed using the logic and the basic structure of the Moral Judgment Test (MJT by Lind (1982. The study aims at understanding how respondents' acceptance of political arguments may have contributed to the lack of international support for the Iraq war and/or to the failure to prevent a preemptive attack. It examines factors, which respondents may have relied on in their acceptance of the arguments. The instrument consisted of three components: (1 A brief vignette on the declared beginning (March 19, 2003 and ending (May 1, 2003 of major operations in Iraq. (2 Respondents' own agreement with the need for the war. (3 Twelve arguments from political speeches: Six arguments by Bush and Blair "in favor of" (pro, and six arguments by Chirac and Schroeder "against" (con the need for the Iraq war. We scored each argument using Kohlberg's (1984 stage theory and Commons' Hierarchical Complexity Scoring System (HCSS (Commons et al., 2004, which identifies hierarchical features in the structure. Using Kempf's (2003 Cognitive Escalation and De-Escalation Model (CEDM we scored each argument sentence for details. Our sample consists of (N = 397 respondents of which were 56.4% women, 24.2% men, and 19.4% did not specify. The largest groups consisted of 71% Germans, 37.2% Catholics, 74.3% between the ages of 18-20 with high school education. Another group consisted of 8.6% Americans with a broader spectrum in age and higher educational level. Using 7 point Likert scales, respondents rated whether they would have rejected or accepted the main point of each argument, whether the main point of the argument seemed illusory or realistic, and whether the emotion evoked by the argument was destructive or constructive. The analysis of the data aimed at determining which within subject and between subject design factors were relevant in predicting respondents' acceptance of arguments and the

    Some association studies, as the implemented in VEGAS, ALIGATOR, i-GSEA4GWAS, GSA-SNP and other software tools, use genes as the unit of analysis. These genes include the coding sequence plus flanking sequences. Polymorphisms in the flanking sequences are of interest because they involve cis-regulatory elements or they inform on untyped genetic variants trough linkage disequilibrium. Gene extensions have customarily been defined as ±50 Kb. This approach is not fully satisfactory because genetic relationships between neighbouring sequences are a function of genetic distances, which are only poorly replaced by physical distances. Standardized recombination rates (SRR) from the deCODE recombination map were used as units of genetic distances. We searched for a SRR producing flanking sequences near the ±50 Kb offset that has been common in previous studies. A SRR≥2 was selected because it led to gene extensions with median length=45.3 Kb and the simplicity of an integer value. As expected, boundaries of the genes defined with the ±50 Kb and with the SRR≥2 rules were rarely concordant. The impact of these differences was illustrated with the interpretation of top association signals from two large studies including many hits and their detailed analysis based in different criteria. The definition based in genetic distance was more concordant with the results of these studies than the based in physical distance. In the analysis of 18 top disease associated loci form the first study, the SRR≥2 genes led to a fully concordant interpretation in 17 loci; the ±50 Kb genes only in 6. Interpretation of the 43 putative functional genes of the second study based in the SRR≥2 definition only missed 4 of the genes, whereas the based in the ±50 Kb definition missed 10 genes. A gene definition based on genetic distance led to results more concordant with expert detailed analyses than the commonly used based in physical distance. The genome coordinates for each

    Metal supply consists of primary material from a mining operation and secondary material, which is composed of new and old scrap. Recycling, which is the use of secondary material, can contribute significantly to metal production, sometimes accounting for more than 50 percent of raw material supply. From 2001 to 2011, U.S. Geological Survey (USGS) scientists studied 26 metals to ascertain the status and magnitude of their recycling industries. The results were published in chapters A-Z of USGS Circular 1196, entitled, "Flow Studies for Recycling Metal Commodities in the United States." These metals were aluminum (chapter W), antimony (Q), beryllium (P), cadmium (O), chromium (C), cobalt (M), columbium (niobium) (I), copper (X), germanium (V), gold (A), iron and steel (G), lead (F), magnesium (E), manganese (H), mercury (U), molybdenum (L), nickel (Z), platinum (B), selenium (T), silver (N), tantalum (J), tin (K), titanium (Y), tungsten (R), vanadium (S), and zinc (D). Each metal commodity was assigned to a single year: chapters A-M have recycling data for 1998; chapters N-R and U-W have data for 2000, and chapters S, T, and X-Z have data for 2004. This 27th chapter of Circular 1196 is called AA; it includes salient data from each study described in chapters A-Z, along with an analysis of overall trends of metals recycling in the United States during 1998 through 2004 and additional up-to-date reviews of selected metal recycling industries from 1991 through 2008. In the United States for these metals in 1998, 2000, and 2004 (each metal commodity assigned to a single year), 84 million metric tons (Mt) of old scrap was generated. Unrecovered old scrap totaled 43 Mt (about 51 percent of old scrap generated, OSG), old scrap consumed was 38 Mt (about 45 percent of OSG), and net old scrap exports were 3.3 Mt (about 4 percent of OSG). Therefore, there was significant potential for increased recovery from scrap. The total old scrap supply was 88 Mt, and the overall new

    To explore the challenges and caring activities of spouses of intensive care unit survivors during the first year of patient recovery. Every year, millions of people globally are discharged from an intensive care unit after critical illness to continue treatment, care and rehabilitation in general hospital wards, rehabilitation facilities and at home. Consequently, millions of spouses become informal caregivers. Little is known, however, about the concrete challenges spouses face in post-intensive care unit everyday life. Explorative, qualitative grounded theory study. Participants were spouses of intensive care unit survivors. The study was undertaken in Denmark in 2009-2010. Data consisted of 35 semi-structured dyad interviews at 3 and 12 months post-intensive care unit discharge, two group interviews with patients and two with spouses. 'Shifting their role from spouse to caregiver and back' was identified as the core category of the study. The role shifts progressed in a dynamic process involving four elements: (1) committing to caregiving; (2) acquiring caregiving skills; (3) negotiating level of caregiving and (4) gradually leaving the caregiver role. Post-ICU caregiving comprised five patient dimensions: observing, assisting, coaching, advocating and managing activities. Spouses play a vital and multifaceted role in post-intensive care unit recovery. The findings can inform healthcare professionals in their efforts to prepare intensive care unit patients' families for the time following intensive care unit and hospital discharge. Hospital staff, rehabilitation experts and primary care professionals must acknowledge spouses' important contribution from intensive care unit admission throughout recovery. © 2015 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Many analyses of microarray association studies involve permutation, bootstrap resampling and cross-validation, that are ideally formulated as embarrassingly parallel computing problems. Given that these analyses are computationally intensive, scalable approaches that can take advantage of multi-core processor systems need to be developed. Results We have developed a CUDA based implementation, permGPU, that employs graphics processing units in microarray association studies. We illustrate the performance and applicability of permGPU within the context of permutation resampling for a number of test statistics. An extensive simulation study demonstrates a dramatic increase in performance when using permGPU on an NVIDIA GTX 280 card compared to an optimized C/C++ solution running on a conventional Linux server. Conclusions permGPU is available as an open-source stand-alone application and as an extension package for the R statistical environment. It provides a dramatic increase in performance for permutation resampling analysis in the context of microarray association studies. The current version offers six test statistics for carrying out permutation resampling analyses for binary, quantitative and censored time-to-event traits.

    Oligotyping is a computational method used to increase the resolution of marker gene microbiome studies. Although oligotyping can distinguish highly similar sequence variants, the resulting units are not necessarily phylogenetically and ecologically informative due to limitations of the selected marker gene. In this perspective, we examine how oligotyping data is interpreted in recent literature, and we illustrate some of the method’s constraints with a case study of the harmful bloom-forming cyanobacterium Microcystis. We identified three Microcystis oligotypes from a western Lake Erie bacterial community 16S rRNA gene (V4 region) survey that had previously clustered into one OTU. We found the same three oligotypes and two additional sequence variants in 46 Microcystis cultures isolated from Michigan inland lakes spanning a trophic gradient. In Lake Erie, shifts in Microcystis oligotypes corresponded to spatial nutrient gradients and temporal transitions in bloom toxicity. In the cultures, Microcystis oligotypes showed preferential distributions for different trophic states, but genomic data revealed that the oligotypes identified in Lake Erie did not correspond to toxin gene presence. Thus, oligotypes could not be used for inferring toxic ecotypes. Most strikingly, Microcystis oligotypes were not monophyletic. Our study supports the utility of oligotyping for distinguishing sequence types along certain ecological features, while it stresses that 16S rRNA gene sequence types may not reflect ecologically or phylogenetically cohesive populations. Therefore, we recommend that studies employing oligotyping or related tools consider these caveats during data interpretation. PMID:28337183

    Full Text Available The continuous increase in the mechanization of farm activities, the rise in fuel prices and the environmental aspects concerning gas emissions are the main driving forces behind efforts toward more effective use of renewable energy sources and cogeneration systems even in agricultural and cattle farms. Nevertheless these systems are still not very suitable for this purpose because of their little flexibility in following the changing energy demand as opposed to the extremely various farm load curves, both in daytime and during the year. In heat recovery systems, the available thermal energy supply is always linked to power production, thus it does not usually coincide in time with the heat demand. Hence some form of thermal energy storage (TES is necessary in order to reach the most effective utilization of the energy source. This study deals with the modelling of a packed bed latent heat TES unit, integrating a cogeneration system made up of a reciprocating engine. The TES unit contains phase change materials (PCMs filled in spherical capsules, which are packed in an insulated cylindrical storage tank. Water is used as heat transfer fluid (HTF to transfer heat from the tank to the final uses, and exhausts from the engine are used as thermal source. PCMs are considered especially for their large heat storage capacity and their isothermal behaviour during the phase change processes. Despite their high energy storage density, most of them have an unacceptably low thermal conductivity, hence PCMs encapsulation technique is adopted in order to improve heat transfer. The special modular configuration of heat exchange tubes and the possibility of changing water flow through them allow to obtain the right amount of thermal energy from the tank, according to the hourly demand of the day. The model permits to choose the electrical load of the engine, the dimensions of the tank and the spheres, thickness and diameter of heat exchanger and the nature of

    In order to improve the wear resistance of gray cast iron guide rail, striature bionic coupling units of different characteristics were manufactured by laser surface remelting. Wear behavior of gray cast iron with striature bionic coupling units has been studied under dry sliding condition at room temperature using a homemade linear reciprocating wear testing machine. The wear resistance was evaluated by means of weight loss measurement and wear morphology. The results indicated that there is a relationship between weight loss and the area of striature bionic coupling units and α: Δm = Δm0 - 0.0212S × cos α - 0.0241S × sin α.

    Childhood overweight/obesity is now epidemic in both developed countries and those undergoing economic transition. This study compared maternal and school-age child nutrition practices and body mass index in the United States and in Chile. Children (125 in the United States, 121 in Chile) and their mothers (116 in the United States, 101 in Chile) participated. Findings indicated that child nutrition practices were comparable, but mothers in the U.S. group demonstrated fewer healthy nutrition practices on behalf of their children. Significant associations were found between maternal and child nutrition practices. Substantially more children in the U.S. sample were overweight/obese. Implications for practice are presented.

    AIM To study the impact of hospital-acquired infections (HAIs) on cost and outcome from intensive care units (ICU) in India. METHODS Adult patients (> 18 years) admitted over 1-year, to a 24-bed medical critical care unit in India, were enrolled prospectively. Treatment cost and outcome data were collected. This cost data was merged with HAI data collected prospectively by the Hospital Infection Control Committee. Only infections occurring during ICU stay were included. The impact of HAI on treatment cost and mortality was assessed. RESULTS The mean (± SD) age of the cohort (n = 499) was 42.3 ± 16.5 years. Acute physiology and chronic health evaluation-II score was 13.9 (95%CI: 13.3-14.5); 86% were ventilated. ICU and hospital length of stay were 7.8 ± 5.5 and 13.9 ± 10 d respectively. Hospital mortality was 27.9%. During ICU stay, 76 (15.3%) patients developed an infection (ventilator-associated pneumonia 50; bloodstream infection 35; urinary tract infections 3), translating to 19.7 infections/1000 ICU days. When compared with those who did not develop an infection, an infection occurring during ICU stay was associated with significantly higher treatment cost [median (inter-quartile range, IQR) INR 92893 (USD 1523) (IQR 57168-140286) vs INR 180469 (USD 2958) (IQR 140030-237525); P < 0.001 and longer duration of ICU (6.7 ± 4.5 d vs 13.4 ± 7.0 d; P < 0.01) and hospital stay (12.4 ± 8.2 d vs 21.8 ± 13.9 d; P < 0.001)]. However ICU acquired infections did not impact hospital mortality (31.6% vs 27.2%; P = 0.49). CONCLUSION An infection acquired during ICU stay was associated with doubling of treatment cost and prolonged hospitalization but did not significantly increase mortality. PMID:28224111

    Full Text Available Existing research on undocumented migration has focused predominantly on Latin American and Mexican immigrants and largely overlooked the experiences of immigrants originating from other parts of the world. As such, very few studies have considered how the lack of legal residency status can influence life opportunities of undocumented immigrants from Eastern Europe. The overarching aim of the present study was to explore the personal experiences of unauthorized Eastern European immigrants in the United States in order to: (a augment research on undocumented migration, and (b highlight the experiences of undocumented Eastern Europeans who remain an understudied group of the undocumented immigrants. Comprehensive personal interviews were conducted with a small group of unauthorized immigrants to explore: (1 reasons for immigration and prior expectations, and (2 psychosocial experiences (i.e., status related anxiety, experience with prejudice and discrimination, job satisfaction, sense of belonging, family relations, and future plans. Some of the results are presented in terms of similarity and differences between the current study's sample and the undocumented immigrants from other regions of the world, namely, Mexico and Latin America.

    Full Text Available BACKGROUND: Migrant workers in the United States have extremely poor health. This paper aims to identify ways in which the social context of migrant farm workers affects their health and health care. METHODS AND FINDINGS: This qualitative study employs participant observation and interviews on farms and in clinics throughout 15 months of migration with a group of indigenous Triqui Mexicans in the western US and Mexico. Study participants include more than 130 farm workers and 30 clinicians. Data are analyzed utilizing grounded theory, accompanied by theories of structural violence, symbolic violence, and the clinical gaze. The study reveals that farm working and housing conditions are organized according to ethnicity and citizenship. This hierarchy determines health disparities, with undocumented indigenous Mexicans having the worst health. Yet, each group is understood to deserve its place in the hierarchy, migrant farm workers often being blamed for their own sicknesses. CONCLUSIONS: Structural racism and anti-immigrant practices determine the poor working conditions, living conditions, and health of migrant workers. Subtle racism serves to reduce awareness of this social context for all involved, including clinicians. The paper concludes with strategies toward improving migrant health in four areas: health disparities research, clinical interactions with migrant laborers, medical education, and policy making.

    This study focuses on the remediation methods and technologies applicable for use at 200-PO-I Groundwater Operable Unit (OU) at the Hanford Site. The 200-PO-I Groundwater au requires groundwater remediation because of the existence of contaminants of potential concern (COPC). A screening was conducted on alternative technologies and methods of remediation to determine which show the most potential for remediation of groundwater contaminants. The possible technologies were screened to determine which would be suggested for further study and which were not applicable for groundwater remediation. COPCs determined by the Hanford Site groundwater monitoring were grouped into categories based on properties linking them by remediation methods applicable to each COPC group. The screening considered the following criteria. (1) Determine if the suggested method or technology can be used for the specific contaminants found in groundwater and if the technology can be applied at the 200-PO-I Groundwater au, based on physical characteristics such as geology and depth to groundwater. (2) Evaluate screened technologies based on testing and development stages, effectiveness, implementability, cost, and time. This report documents the results of an intern research project conducted by Mathew Dado for Central Plateau Remediation in the Soil and Groundwater Remediation Project. The study was conducted under the technical supervision of Gloria Cummins and management supervision of Theresa Bergman and Becky Austin.

    2009-07-01

    Acoustic imaging noise produced during functional magnetic resonance imaging (fMRI) studies can hinder auditory fMRI research analysis by altering the properties of the acquired time-series data. Acoustic imaging noise can be especially confounding when estimating the time course of the hemodynamic response (HDR) in auditory event-related fMRI (fMRI) experiments. This study is motivated by the desire to establish a baseline function that can serve not only as a comparison to other quantities of acoustic imaging noise for determining how detrimental is one's experimental noise, but also as a foundation for a model that compensates for the response to acoustic imaging noise. Therefore, the amplitude and spatial extent of the HDR to the elemental unit of acoustic imaging noise (i.e., a single ping) associated with echoplanar acquisition were characterized and modeled. Results from this fMRI study at 1.5 T indicate that the group-averaged HDR in left and right auditory cortex to acoustic imaging noise (duration of 46 ms) has an estimated peak magnitude of 0.29% (right) to 0.48% (left) signal change from baseline, peaks between 3 and 5 s after stimulus presentation, and returns to baseline and remains within the noise range approximately 8 s after stimulus presentation.

    Although the use of resilience skills (RSs) by emergency department (ED) front-line staff is ubiquitous, the nature and origin of these skills tend to be taken for granted. This study investigates the research question "where do RSs come from"? Case studies in two EDs were undertaken in order to answer the research question: one in Brazil and the other in the United States. The case studies adopted the same data collection and analysis procedures, involving interviews, questionnaires, observations, and analysis of documents. A model for describing RSs as emergent phenomena is proposed. The model indicates that RSs arise from interactions between: work constraints, hidden curriculum, gaps in standardized operating procedures, organizational support for resilience, and RSs themselves. An instantiation of the model is illustrated by a critical event identified from the American ED. The model allows the identification of leverage points for influencing the development of RSs, instead of leaving their evolution purely to chance. Copyright © 2016 Elsevier Ltd.

    Full Text Available AIM: To study the mechanism of road traffic collisions (RTC, use of safety devices, and outcome of hospitalized pediatric and youth RTC injured patients so as to give recommendations regarding prevention of pediatric RTC injuries. METHODS: All RTC injured children and youth (0-19-year-olds who were admitted to Al Ain City's two major trauma centers or who died after arrival to these centers were prospectively studied from April 2006 to October 2007. Demography of patients, road-user and vehicle types, crash mechanism, usage of safety devices, injured body regions, injury severity, Revised Trauma Score, Glasgow Coma Scale, intensive care unit admissions, hospital stay and mortality were analyzed. RESULTS: 245 patients were studied, 69% were vehicle occupants, 15% pedestrians, 9% motorcyclists and 5% bicyclists. 79% were males and 67% UAE citizens. The most common mechanism of RTC was rollover of vehicle (37% followed by front impact collision (32%. 32 (13% of vehicle occupants were ejected from car. 63% of ejected occupants and 70% of motorcyclists sustained head injuries. Only 2% (3/170 vehicle passengers used seatbelts and 13% (3/23 motorcyclists a helmet. CONCLUSIONS: Male drivers and UAE nationals were at high risk of RTC as drivers and as motorcyclists. Ejection rate was high because safety restraint use was extremely low in our community. More education and law enforcement focusing especially on car/booster seat use is needed.

    Groundwater quality in the 48-square-mile Santa Barbara study unit was investigated in 2011 as part of the California State Water Resources Control Board’s Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project. The study unit is mostly in Santa Barbara County and is in the Transverse and Selected Peninsular Ranges hydrogeologic province. The GAMA Priority Basin Project is carried out by the U.S. Geological Survey in collaboration with the California State Water Resources Control Board and Lawrence Livermore National Laboratory.The GAMA Priority Basin Project was designed to provide a statistically unbiased, spatially distributed assessment of the quality of untreated groundwater in the primary aquifer system of California. The primary aquifer system is defined as that part of the aquifer corresponding to the perforation interval of wells listed in the California Department of Public Health database for the Santa Barbara study unit. This status assessment is intended to characterize the quality of groundwater resources in the primary aquifer system of the Santa Barbara study unit, not the treated drinking water delivered to consumers by water purveyors.The status assessment for the Santa Barbara study unit was based on water-quality and ancillary data collected in 2011 by the U.S. Geological Survey from 23 sites and on water-quality data from the California Department of Public Health database for January 24, 2008–January 23, 2011. The data used for the assessment included volatile organic compounds; pesticides; pharmaceutical compounds; two constituents of special interest, perchlorate and N-nitrosodimethylamine (NDMA); and naturally present inorganic constituents, such as major ions and trace elements. Relative-concentrations (sample concentration divided by the health- or aesthetic-based benchmark concentration) were used to evaluate groundwater quality for those constituents that have federal or California regulatory and non

  3. RNA editing and modifications of RNAs might have favoured the evolution of the triplet genetic code from an ennuplet code.

    2014-10-21

    Here we suggest that the origin of the genetic code, that is to say, the birth of first mRNAs has been triggered by means of a widespread modification of all RNAs (proto-mRNAs and proto-tRNAs), as today observed in the RNA editing and in post-transcriptional modifications of RNAs, which are considered as fossils of this evolutionary stage of the genetic code origin. We consider also that other mechanisms, such as the trans-translation and ribosome frameshifting, could have favoured the transition from an ennuplet code to a triplet code. Therefore, according to our hypothesis all these mechanisms would be reflexive of this period of the evolutionary history of the genetic code. Copyright © 2014. Published by Elsevier Ltd.

    Children with Dravet syndrome (DS) often have severe cognitive, behaviour and motor impairments. Patients with truncating mutations would logically have the more severe phenotype. Here we present a case of DS with an unusually favourable cognitive and behavioral development with a novel SCN1A frameshift mutation (c.4233-4234insAT). Under regular following up for ten years, the patient had normal expressive language and mild motor clumsiness. It is suggested that besides the type of SCN1A mutation, other mechanisms may be existed to influence the SCN1A phenotype, such as modifier genes, developmental variability, accumulation of somatic mutation in lifetime and environmental insults can all contribute to the cognitive and behavioral outcome.

    To evaluate the potential impact of two alcohol control policies under consideration in England: banning below cost selling of alcohol and minimum unit pricing. Modelling study using the Sheffield Alcohol Policy Model version 2.5. England 2014-15. Adults and young people aged 16 or more, including subgroups of moderate, hazardous, and harmful drinkers. Policy to ban below cost selling, which means that the selling price to consumers could not be lower than tax payable on the product, compared with policies of minimum unit pricing at £0.40 (€0.57; $0.75), 45 p, and 50 p per unit (7.9 g/10 mL) of pure alcohol. Changes in mean consumption in terms of units of alcohol, drinkers' expenditure, and reductions in deaths, illnesses, admissions to hospital, and quality adjusted life years. The proportion of the market affected is a key driver of impact, with just 0.7% of all units estimated to be sold below the duty plus value added tax threshold implied by a ban on below cost selling, compared with 23.2% of units for a 45 p minimum unit price. Below cost selling is estimated to reduce harmful drinkers' mean annual consumption by just 0.08%, around 3 units per year, compared with 3.7% or 137 units per year for a 45 p minimum unit price (an approximately 45 times greater effect). The ban on below cost selling has a small effect on population health-saving an estimated 14 deaths and 500 admissions to hospital per annum. In contrast, a 45 p minimum unit price is estimated to save 624 deaths and 23,700 hospital admissions. Most of the harm reductions (for example, 89% of estimated deaths saved per annum) are estimated to occur in the 5.3% of people who are harmful drinkers. The ban on below cost selling, implemented in the England in May 2014, is estimated to have small effects on consumption and health harm. The previously announced policy of a minimum unit price, if set at expected levels between 40 p and 50 p per unit, is estimated to have an approximately 40-50 times

    Quantitative EMG reflects denervation of muscles after lower motor neuron degeneration in spinal muscular atrophy (SMA) but does not reflect actual motor unit loss. The aim of our study was to assess the value of the multipoint incremental motor unit number estimation (MUNE) method in the modification by Shefner in estimating motor unit loss in SMA. The number of motor units, the mean amplitude of an average surface-detected single motor unit potential (SMUP), and the amplitude of compound motor action potentials (CMAP) were estimated in 14 children with SMA in the abductor pollicis brevis (ABP). Significant differences in MUNE values and SMUP and CMAP amplitude were found between the SMA and control groups (P < 0.0001). MUNE values correlated with Hammersmith Functional Motor Scale (HFMS) scores (P < 0.05). Increased SMUP amplitude values correlated with decreased HFMS scores (P < 0.05). The study confirms that MUNE method in the modification by Shefner is a useful tool reflecting motor unit loss in SMA, and it is easy to perform and well tolerated. MUNE and SMUP amplitude seemed to be sensitive parameters reflecting motor dysfunction in SMA but a longitudinal study in a larger number of subjects is needed.

    This study aimed to determine how much time can be saved with the use of unit-of-use packaging for prescription drugs as compared with bulk packaging in community pharmacies as well as to determine the number of errors. In a simulation, mock prescriptions were dispensed either in unit-of-use packages or by transferring medication from a bulk container, and a time study was conducted to measure the time spent on dispensing and prescription auditing by pharmacists. Pharmacists' and patients' degree of satisfaction was also surveyed. The time saved with unit-of-use packaging was 66.25 s per prescription. The sole dispensing error that was found in the study occurred with bulk dispensing. Among both pharmacists and patients, many were of the opinion that dispensing with unit-of-use packaging was preferable to bulk dispensing. Unit-of-use packaging shortens the time that pharmacists spend on dispensing activities and increases the efficiency of their work. Unit-of-use packaging is also thought to reduce the number of counting errors.

    Various staffing measures have been used in examining the relationship between nurse staffing and patient outcomes. Little research has been conducted to compare these measures based on their explanatory power as predictors of nursing-sensitive outcomes. In this study, both administrative and nurse-reported measures were examined. Administrative measures included registered nurse (RN) skill mix and three versions of nursing hours per patient day (HPPD); nurse-reported measures included RN-reported number of assigned patients and RN-perceived staffing adequacy. To examine correlations among six nurse staffing measures and to compare their explanatory power in relation to unit-acquired pressure ulcers (UAPUs). Descriptive, correlational study. 2397 nursing units in 409 U.S. acute care hospitals. Random-intercept logistic regression analyses were performed using 2011 data from a national database. Relationships between nurse staffing measures and UAPU occurrences were examined in eight models, each with one or more staffing measures as predictors. Characteristics of nursing units (RN workgroup education level and RN workgroup unit tenure) and hospitals (size, teaching status, and Magnet status) were included as control variables. Two versions of HPPD (total nursing HPPD and RN HPPD) and RN skill mix were significantly correlated with RN-reported number of assigned patients (r range=-0.87 to -0.75). These staffing measures had weaker correlations with RN-perceived staffing adequacy (r range=0.16 to 0.23). Of the six staffing variables, only RN-perceived staffing adequacy and RN skill mix were significantly associated with UAPU odds, the former being the better predictor. Although RN-perceived staffing adequacy was not highly correlated with administrative measures of HPPD and RN skill mix, it was the strongest predictor of UAPU occurrences. RN-perceived staffing adequacy can serve as a more appropriate measure of staffing for nursing-sensitive outcomes research than

  20. Authentic science in education: Studies in course-based research at the United States Military Academy

    Science.gov (United States)

    Chase, Anthony M.

    This dissertation consists of two studies at the United States Military Academy. Both studies involve the use of Course-based Undergraduate Research Experiences (CUREs). These experiences give students the ability to engage in undergraduate research at an early point in their academic career by replacing traditional laboratory activities with semester-long research projects. Both studies show an implementation of this type of instruction from the Center for Authentic Science Practice in Education (CASPiE). Study 1 shows the specific method of implementation at the military academy and explores learning-based outcomes. Primarily the outcome of critical thinking is demonstrated. Critical thinking is a construct that many curriculum developers and instructors want to foster within their students but often lack clear definitions or evaluation plans. This study gives a definition of critical thinking and an outcome of a critical thinking test. Significant gains in critical thinking are observed by students participating in the CURE as well as significant gains in three affective factors (Interest in Science/Chemistry, Authenticity, Perceived Learning). The gains in critical thinking are then further statistically linked to students’ perceptions of how authentically they saw the research in the course. If they felt that the course was demonstrating more authentic science practices, they gained significantly more in their critical thinking scores. The second study in this dissertation adds an additional transfer focus to the instructional materials that the CURE was meant to support. The treatment group in this study received instruction that was framed expansively. The expansively framed instruction showed students ways that the material was applicable outside of the course. The assessments and instructional materials of this study were transfer assessments with contrasting cases. Instances of negative or “overzealous transfer” were also reported. Findings suggest

    The Hanford Site, managed by the U.S. Department of Energy (DOE), encompasses approximately 1,517 km{sup 2} (586 mi{sup 2}) in the Columbia Basin of south-central Washington State. In 1989, the U.S. Environmental Protection Agency (EPA) placed the 100, 200, 300, and 1100 Areas of the Hanford Site on the 40 Code of Federal Regulations (CFR) 300, 'National Oil and Hazardous Substances Pollution Contingency Plan' National Contingency Plan [NCPD], Appendix B, 'National Priorities List' (NPL), pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The 200 Areas NPL sites consist of the 200 West and 200 East Areas (Figure 1-1). The 200 Areas contain waste management facilities, inactive irradiated fuel reprocessing facilities, and the 200 North Area (formerly used for interim storage and staging of irradiated fuel). Several waste sites in the 600 Area, located near the 200 Areas, also are included in the 200 Areas NPL site. The 200 Areas NPL site is in a region referred to as the 'Central Plateau' and consists of approximately 700 waste sites, excluding sites assigned to the tank farm waste management areas (WMAs). The 200-ZP-1 Groundwater Operable Unit (OU) consists of the groundwater located under the northern portion of the 200 West Area. Waste sources that contributed to the 200-ZP-1 OU included cribs and trenches that received liquid and/or solid waste in the past from the Z Plant and T Plant aggregate areas, WMA-T, WMA-TX/TY, and the State-Approved Land Disposal Site (SALDS). This feasibility study (FS) for the 200-ZP-1 Groundwater OU was prepared in accordance with the requirements of CERCLA decision documents. These decision documents are part of the Administrative Record for the selection of remedial actions for each waste site and present the selected remedial actions that are chosen in accordance with CERCLA, as amended by the Superfund Amendments and Reauthorization Act of 1986

This Phase I/II study provides a generalized view of workable remedial technologies as applied to the site contamination problems as a whole. Phase III, Detailed Analysis of Alternatives, will be performed at a later date to further evaluate screened alternatives based on the nine criteria in the CERCLA RI/FS guidance. The purpose of this Phase I/II FS is to develop and screen a range of alternatives for remediation of contamination present in the vadose zone of the 300-FF-1 OU. The scope of work for this Phase I/II FS includes five primary tasks: 1. Review existing documents and their associated data from relevant investigations and studies; 2. Establish remedial action objectives (RAO) and general response actions (GRA); 3. Identify applicable or relevant and appropriate requirements (ARARS) pertinent to all general response actions (including waste disposal); 4. Develop remedial alternatives (Phase I) applicable to the 300-FF-1 OU including identification and screening of technologies and process options, and assembly of remedial alternatives from representative technology types; 5. Screen alternatives (Phase II) developed in Phase I for implementability, effectiveness, and cost to identify those alternatives which warrant advancement to the detailed analysis phase (Phase III) of the FS.

    Background To the best of our knowledge, there are no studies evaluating the influence of the unit of the first contact on the frequency and time of pharmacological treatment during an acute coronary syndrome (ACS) event. Objectives The main objective was to investigate if the unit of first contact influenced the frequency and time of aspirin treatment in the Strategy of Registry of Acute Coronary Syndrome (ERICO) study. Methods We analyzed the pharmacological treatment time in 830 ERICO participants - 700 individuals for whom the hospital was the unit of first contact and 130 who initially sought primary care units. We built logistic regression models to study whether the unit of first contact was associated with a treatment time of less than three hours. Results Individuals who went to primary care units received the first aspirin dose in those units in 75.6% of the cases. The remaining 24.4% received aspirin at the hospital. Despite this finding, individuals from primary care still had aspirin administered within three hours more frequently than those who went to the hospital (76.8% vs 52.6%; p<0.001 and 100% vs. 70.7%; p=0.001 for non ST-elevation ACS and ST-elevation myocardial infarction, respectively). In adjusted models, individuals coming from primary care were more likely to receive aspirin more quickly (odds ratio: 3.66; 95% confidence interval: 2.06-6.51). Conclusions In our setting, individuals from primary care were more likely to receive aspirin earlier. Enhancing the ability of primary care units to provide early treatment and safe transportation may be beneficial in similar settings. PMID:27849262

    More than 30 power units of thermal power stations, based on the nondeaerating heat balance diagram, successfully operate in the former Soviet Union. Most of them are power units with a power of 300 MW, equipped with HTGZ and LMZ turbines. They operate according to a variable electric load curve characterized by deep reductions when undergoing night minimums. Additional extension of the range of power unit adjustment makes it possible to maintain the dispatch load curve and obtain profit for the electric power plant. The objective of this research is to carry out estimated and experimental processing of the operating regimes of the regeneration system of steam-turbine plants within the extended adjustment range and under the conditions when the constraints on the regeneration system and its equipment are removed. Constraints concerning the heat balance diagram that reduce the power unit efficiency when extending the adjustment range have been considered. Test results are presented for the nondeaerating heat balance diagram with the HTGZ turbine. Turbine pump and feed electric pump operation was studied at a power unit load of 120-300 MW. The reliability of feed pump operation is confirmed by a stable vibratory condition and the absence of cavitation noise and vibration at a frequency that characterizes the cavitation condition, as well as by oil temperature maintenance after bearings within normal limits. Cavitation performance of pumps in the studied range of their operation has been determined. Technical solutions are proposed on providing a profitable and stable operation of regeneration systems when extending the range of adjustment of power unit load. A nondeaerating diagram of high-pressure preheater (HPP) condensate discharge to the mixer. A regeneration system has been developed and studied on the operating power unit fitted with a deaeratorless thermal circuit of the system for removing the high-pressure preheater heating steam condensate to the mixer

    2008-01-01

    A time-and-motion study was conducted in response to perceptions that the surgical nursing staff at a Montreal hospital was spending an excessive amount of time on non-nursing care. A sample of 30 nurse shifts was observed by trained observers who timed nurses' activities for their entire working shift using a hand-held Personal Digital Assistant. Activities were grouped into four main categories: direct patient care, indirect patient care, non-nursing and personal activities. Break and meal times were excluded from the denominator of total worked hours. A total of 201 working hours were observed, an average of 6 hours, 42 minutes per nurse shift. The mean proportions of each nurse shift spent on the main activity categories were: direct care 32.8%, indirect care 55.7%, non-nursing tasks 9.0% and personal 2.5%. Three activities (communication among health professionals, medication verification/preparation and documentation) comprised 78.9% of indirect care time. Greater time on indirect care was associated with work on night shifts and on the short-stay surgical unit. Subsequent work reorganization focused on reducing time spent on communication and medications. The authors conclude that time-and-motion studies are a useful method of monitoring appropriate use of nursing staff, and may provide results that assist in restructuring nursing tasks.

    Full Text Available Background. Conjunctivitis is one of the most frequently occurring hospital-acquired infections among neonates, although it is less studied than potentially life-threatening infections, such as sepsis and pneumonia. Objectives. The aims of our work were to identify epidemiologic characteristics, pathogens, and susceptibility patterns of bacterial hospital-acquired conjunctivitis (HAC in a level III neonatal unit. Materials and Methods. Data were collected retrospectively from patient charts and laboratory databases. Hospital-acquired conjunctivitis was defined in accordance with the Centers for Disease Control/National Healthcare Safety Network (CDC/NHSN diagnostic criteria. Results. One or more episodes of HAC were diagnosed in 4,0% ( of 1492 neonates admitted during the study period. Most of the episodes involved premature (75,4% and low birth weight (75,4% neonates. Infection rates were higher among patients undergoing noninvasive mechanical ventilation (46,7%, parenteral nutrition (13,6%, and phototherapy (6,8%. Predominant pathogens included Serratia marcescens (27,9%, Escherichia coli (23%, and Pseudomonas aeruginosa (18%. Susceptibility patterns revealed bacterial resistances to several antibiotic classes. Gentamicin remains the adequate choice for empirical treatment of HAC in our NICU. Conclusion. It is important to know the local patterns of the disease in order to adjust prevention strategies. Our work contributes to the epidemiological characterization of a sometimes overlooked disease.

    A case-control study of bladder cancer was conducted in five United States rubber and tyre companies to determine if there were high-risk jobs and work areas within the industry. The study included 220 male cases of bladder cancer, of whom 107 were identified from hospital record reviews and 113 from death certificates. Each case was matched individually with two industry controls by sex, race, year of birth, and company. One control was matched additionally by year of hire and duration of employment. Comparisons of cases and controls not matched by year of hire and age of hire showed no differences for those variables, which suggests that age and calendar period of first exposure to the industry were not risk determinants. When the work histories of both cases and controls were contrasted it was found that cases were more likely than controls to have worked in milling (odds ratio (OR) = 1.91) and calender operation (OR = 2.21) jobs. The relative risk estimates for milling and calender operation both exhibited linear trends of increase with duration of exposure. Milling and calender operation jobs entail potential exposures to volatilised reaction products from heated rubber stock. A better understanding of aetiological associations with job type will require more detailed characterisation of the work environment with regard to the sources and levels of aromatic amines and other suspected bladder carcinogens.

    Numerous epidemiologic investigations have identified links between high concentrations of arsenic in drinking water and cancer, although the risks at lower exposures are largely unknown. This paper presents the results of a case-control study of arsenic ingestion and bladder cancer in seven counties in the western United States. These counties contain the largest populations historically exposed to drinking water arsenic at concentrations near 100 microg/liter. All incident cases diagnosed from 1994 to 2000 were recruited. Individual data on water sources, water consumption patterns, smoking, and other factors were collected for 181 cases and 328 controls. Overall, no increased risks were identified for arsenic intakes greater than 80 microg/day (odds ratio=0.94, 95% confidence interval: 0.56, 1.57; linear trend, p=0.48). These risks are below predictions based on high dose studies from Taiwan. When the analysis was focused on exposures 40 or more years ago, an odds ratio of 3.67 (95% confidence interval: 1.43, 9.42; linear trend, p<0.01) was identified for intakes greater than 80 microg/day (median intake, 177 microg/day) in smokers. These data provide some evidence that smokers who ingest arsenic at concentrations near 200 microg/day may be at increased risk of bladder cancer.

    Background. Conjunctivitis is one of the most frequently occurring hospital-acquired infections among neonates, although it is less studied than potentially life-threatening infections, such as sepsis and pneumonia. Objectives. The aims of our work were to identify epidemiologic characteristics, pathogens, and susceptibility patterns of bacterial hospital-acquired conjunctivitis (HAC) in a level III neonatal unit. Materials and Methods. Data were collected retrospectively from patient charts and laboratory databases. Hospital-acquired conjunctivitis was defined in accordance with the Centers for Disease Control/National Healthcare Safety Network (CDC/NHSN) diagnostic criteria. Results. One or more episodes of HAC were diagnosed in 4,0% (n = 60) of 1492 neonates admitted during the study period. Most of the episodes involved premature (75,4%) and low birth weight (75,4%) neonates. Infection rates were higher among patients undergoing noninvasive mechanical ventilation (46,7%), parenteral nutrition (13,6%), and phototherapy (6,8%). Predominant pathogens included Serratia marcescens (27,9%), Escherichia coli (23%), and Pseudomonas aeruginosa (18%). Susceptibility patterns revealed bacterial resistances to several antibiotic classes. Gentamicin remains the adequate choice for empirical treatment of HAC in our NICU. Conclusion. It is important to know the local patterns of the disease in order to adjust prevention strategies. Our work contributes to the epidemiological characterization of a sometimes overlooked disease.

    Geographic variations in mortality rate in the United States could be due to several hypothesized factors, one of which is exposure to solar ultraviolet radiation (UVR). Limited evidence from previous prospective studies has been inconclusive. The association between ambient residential UVR exposure and total and cause-specific mortality risks in a regionally diverse cohort (346,615 white, non-Hispanic subjects, 50-71 years of age, in the National Institutes of Health (NIH)-AARP Diet and Health Study) was assessed, with accounting for individual-level confounders. UVR exposure (averaged for 1978-1993 and 1996-2005) from NASA's Total Ozone Mapping Spectrometer was linked to the US Census Bureau 2000 census tract of participants' baseline residence. Multivariate-adjusted Cox proportional-hazards models were used to estimate hazard ratios and 95% confidence intervals. Over 12 years, UVR exposure was associated with total deaths (n = 41,425; hazard ratio for highest vs. lowest quartiles (HRQ4 vs. Q1) = 1.06, 95% confidence interval (CI): 1.03, 1.09; Ptrend exposure might not be beneficial for longevity.

  14. Heat Mortality Versus Cold Mortality: A Study of Conflicting Databases in the United States.

    Studies, public reports, news reports, and Web sites cite a wide range of values associated with deaths resulting from excessive heat and excessive cold. For example, in the United States, the National Climatic Data Center's Storm Data statistics of temperature- related deaths are skewed heavily toward heat-related deaths, while the National Center for Health Statistics Compressed Mortality Database indicates the reverse—4 times more people die of “excessive cold” conditions in a given year than of “excessive heat.” In this study, we address the fundamental differences in the various temperature-related mortality databases, assess their benefits and limitations, and offer suggestions as to their use. These datasets suffer from potential incompleteness of source information, long compilation times, limited quality control, and the subjective determination of a direct versus indirect cause of death. In general, these separate mortality datasets should not be combined or compared, particularly with regard to policy determination. The use of gross mortality numbers appears to be one of the best means of determining temperature-related mortality, but those data must be detrended into order to remove a persistent winter-dominant death maximum and are difficult to obtain on a regional daily basis.

    Introduction: Hypomagnesemia has been common, but mostly underdiagnosed electrolyte abnormality. Studies regarding this is lacking in India especially in rural setting. Here, we have correlated serum magnesium (Mg) level with outcome in patients of medicine Intensive Care Unit (ICU) with respect to length of ICU stay, need for mechanical ventilatory support and its duration and ultimate outcome (discharge/death). Materials and Methods: This is a prospective observational study carried out over a period of 1-year enrolling 601 patients of Medical ICU (MICU). The Chi-square test is applied to correlate hypomagnesemia with the outcome. Result and Observation: About 25% patients had admission hypomagnesemia. When compared with the normal Mg group, there was significant association of hypomagnesemia with outcome in terms of duration of MICU stay 5.46 (5.75) versus 3.93 (3.88), need for mechanical ventilation (56.86% vs. 24.33%), discharge/cured from ICU (61.43% vs. 85.26%), and death (38.56% vs. 14.73%). However, no significant difference was found in the duration of ventilation between the two groups. Conclusion: Hypomagnesemia is associated with a higher mortality rate in critically ill patients. The need for ventilatory support, but not its duration is significantly higher in hypomagnesemic patients. Hypomagnesemia is commonly associated with sepsis and diabetes mellitus. The duration of MICU stay is significantly higher in patients with low serum Mg. PMID:26180429

    Full Text Available Forest management plans were firstly prepared and implemented in Turkey between 1963 and 1973. All forests in Turkey have been managed with timber oriented forest management philosophy; however, there have been some developments about inventory and silviculture techniques for approximately 40 years. Last decade, Turkey participated in Convention of Biological Diversity in Rio (1992 and included in both Pan – European and Near East Region Conventions. Nowadays, Turkish forest management philosophy has changed from timber management to ecosystem-based multiple-use forest planning with the principles of “sustainable forest management” criteria and indicators drafted in a few national and international agreements. Thus, Turkish forestry is underway in a restructuring process. This paper presents evolution of the traditional forest management philosophy in Turkey since 1963. This study was carried out in Artvin Planning Unit. Past two decade planning periods (managed under timber management approach was compared with current case study data used for forest multiple use management approach based on ecosystem in terms of distribution of age class, site class and change of volume and increment. In conclusion, former applications and techniques for adaptation of improvement must be analyzed and interpreted properly. Monetary resources and experts as well as legal, technique and scientific framework must be provided.

    The cross flow fan is a unique type of turbo machinery where the air stream flows transversely across the impeller, passing the blades twice. Due to its complex geometry, and highly turbulent and unsteady air-flow, a numerical method is used in this work to conduct the characterization study on the performance of a cross flow fan. A 2D cross-sectional model of a typical indoor air conditioning unit has been chosen for the simulation instead of a three dimensional 3D model due to the highly complex geometry of the fan. The simplified 2D model has been validated with experiments where it is found that the RMS error between the simulation and experimental results is less than 7%. The important parameters that affect the cross flow fan performance, i.e. the internal and external blade angles, the blade thickness, and the casing design, are analyzed in this study. The formation of an eccentric vortex is observed within the impeller.

    In this research, we studied the incidence of pressure ulcer and risk factors and screening of the patients for pressure ulcers at intensive care unit on the first day of admission in 142 patients. All patients were evaluated according to National Pressure Ulcer Advisory Panel during the ICU period strictly. Pressure ulcer risk evaluation was performed according to Norton Scale. Nutritional state was evaluated according to nutritional risk screening 2002. Age, hospitalization period, mean arterial pressure, pressure ulcer degree, hemoglobin and albumin levels, body mass index, APACHE-II scores and comorbidities were evaluated. In the following parameters, first value represents PU (+) cases, and second value represents PU (-) cases. On the admittance: 14 (9.8%) patients had PU (prevalence). NRS-2002: 5.4+/-1.9 and 4.3+/-2.1 (p0.05). Mean pressure ulcer degree was 2.15. On the discharge: first values represent new developed PU (+) patients and second values represent PU (-) cases. 25 (17.6%) patients had PU. Incidence was 7.8%. NRS-2002: 6.4 and 3.6 (p0.05). Two or more co morbidity, neurophyschiatric disorders, infections and medications were more prevalent in PU (+) group (pmalnutrition and hypoalbuminemia were significant in patients with PU; however, BMI and hemoglobin were not significant. The studies focusing on the relation between the effect of optimization of these parameters from the first day of admittance and pressure ulcer are required.

    Short-stay treatment has become a popular form of care as a strategy to cope with increased demands on health care. There is little research that considers children's experiences of acute hospitalisation to a short-stay care facility such as a Paediatric Emergency and Assessment Unit (PEAU). This study explored the experiences of eight children aged 8-10 years. Semi-structured interviews were carried out to investigate the children's own experiences of being hospitalised in a PEAU. Thematic content analyses were used. Three major themes were identified: the children's understanding of disease, treatment and procedures; the children's experiences of health-care personnel and the PEAU and transformation of everyday life into the settings of the hospital. The children identified the hospital stay as an overall positive experience. The children took part in leisure activities as they would at home and enjoyed time together with their parents while in hospital. In their conversations with staff they adapted to professional terms that they did not necessarily understand. They did not differentiate between professionals. Further work should be considered to clarify the consequences of this. This study has provided some limited insight into the child's experiences of acute hospitalisation, which should inform nursing care.

  20. Remedial investigation/feasibility study work plan for the 100-BC-2 operable unit, Hanford Site, Richland, Washington

    This work plan and attached supporting project plans establish the operable unit setting and the objectives, procedures, tasks, and schedule for conducting the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) remedial investigation/feasibility study (RI/FS) for the 100-BC-2 operable unit in the 100 Area of the Hanford Site. The 100 Area is one of four areas at the Hanford Site that are on the US Environmental Protection Agency`s (EPA) National Priorities List under CERCLA. The 100-BC-2 operable unit is one of two source operable units in the 100-B/C Area (Figure ES-1). Source operable units are those that contain facilities and unplanned release sites that are potential sources of hazardous substance contamination. The 100-BC-2 source operable unit contains waste sites that were formerly in the 100-BC-2, 100-BC-3, and 100-BC-4 operable units. Because of their size and geographic location, the waste sites from these two operable units were added to 100-BC-2. This allows for a more efficient and effective investigation of the remaining 100-B/C Reactor area waste sites. The investigative approach to waste sites associated with the 100-BC-2 operable unit are listed in Table ES-1. The waste sites fall into three general categories: high priority liquid waste disposal sites, low priority liquid waste disposal sites, and solid waste burial grounds. Several sites have been identified as candidates for conducting an IRM. Two sites have been identified as warranting additional limited field sampling. The two sites are the 116-C-2A pluto crib, and the 116-C-2C sand filter.

    The Hanford Site, managed by the U.S. Department of Energy (DOE), encompasses approximately 1,517 km{sup 2} (586 mi{sup 2}) in the Columbia Basin of south-central Washington State. In 1989, the U.S. Environmental Protection Agency (EPA) placed the 100, 200, 300, and 1100 Areas of the Hanford Site on the 40 Code of Federal Regulations (CFR) 300, 'National Oil and Hazardous Substances Pollution Contingency Plan' National Contingency Plan [NCPD], Appendix B, 'National Priorities List' (NPL), pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The 200 Areas NPL sites consist of the 200 West and 200 East Areas (Figure 1-1). The 200 Areas contain waste management facilities, inactive irradiated fuel reprocessing facilities, and the 200 North Area (formerly used for interim storage and staging of irradiated fuel). Several waste sites in the 600 Area, located near the 200 Areas, also are included in the 200 Areas NPL site. The 200 Areas NPL site is in a region referred to as the 'Central Plateau' and consists of approximately 700 waste sites, excluding sites assigned to the tank farm waste management areas (WMAs). The 200-ZP-1 Groundwater Operable Unit (OU) consists of the groundwater located under the northern portion of the 200 West Area. Waste sources that contributed to the 200-ZP-1 OU included cribs and trenches that received liquid and/or solid waste in the past from the Z Plant and T Plant aggregate areas, WMA-T, WMA-TX/TY, and the State-Approved Land Disposal Site (SALDS). This feasibility study (FS) for the 200-ZP-1 Groundwater OU was prepared in accordance with the requirements of CERCLA decision documents. These decision documents are part of the Administrative Record for the selection of remedial actions for each waste site and present the selected remedial actions that are chosen in accordance with CERCLA, as amended by the Superfund Amendments and Reauthorization Act of 1986

    The national forests (NFs) in the United States are protected areas managed for multiple purposes, and therefore are subject to both natural and anthropogenic disturbances. Monitoring forest changes arising from such disturbances and the post-disturbance recovery processes is essential for assessing the conditions of the NFs and the effectiveness of management approaches. In this study, we used time series stacks of Landsat images (LTSS) to evaluate the dynamics of seven NFs in eastern United States, including the De Soto NF, the Talladega NF, the Francis Marion NF, and the Uwharrie NF in southeastern U.S., and the Chequamegon NF, the Hiawatha NF, and the Superior NF in northern U.S. Each LTSS consisted of 12-14 Landsat images acquired for the same location, spanning from 1984 to 2006 with a nominal interval of one image every 2??years. Each LTSS was analyzed using a vegetation change tracker (VCT) algorithm to map forest disturbance. Accuracy assessments of the derived disturbance maps revealed that they had overall accuracy values of about 80%, with most of the disturbance classes having user's accuracies ranging from 70% to 95%. The producer's accuracies were generally lower, with the majority being in the range between 50% and 70%. While this may suggest that the disturbance maps could slightly underestimate disturbances, a more detailed assessment of the omission errors revealed that the majority of the disagreements were due to minor disturbances like thinning or storm damages that were identified by the image analysts but were not captured by the VCT algorithm. The derived disturbance year maps revealed that while each of the seven NFs consisted of 90% or more forest land, significant portions of the forests were disturbed since 1984. Mapped disturbances accounted for about 30%-45% of total land area in the four NFs in southeastern U.S. and about 10%-20% in the three NFs in northern U.S. The disturbance rates were generally higher in the buffer zones

    The aerodynamic and aeroacoustic performances of outdoor unit with two different types of grille have been investigated in present study. Experimental results indicate that the grille sharp will affect the flow rate and increase broadband noise level of outdoor unit. Based on noise generation mechanism and CFD simulation, vortex shedding noise model and inlet turbulence noise model are adopted to predict the broadband noise level of outdoor unit. When vortex shedding noise is concerned, the wake parameters should be calculated at 3 mm downstream of grille to achieve good accuracy. Inlet turbulence noise is generated from the interaction between blade wake and the grille, and plays less important role in present outdoor unit configuration. In comparison with experimental results, it is shown that the broadband noise prediction method could provide reasonable accuracy and the error between prediction and experiment is less than 1 dBA.

    Full Text Available BACKGROUND: There have been dramatic increases over the past 20 years in the number of nonacademic, private-sector physicians who serve as principal investigators on US clinical trials sponsored by the pharmaceutical industry. However, there has been little research on the implications of these investigators' role in clinical investigation. Our objective was to study private-sector clinics involved in US pharmaceutical clinical trials to understand the contract research arrangements supporting drug development, and specifically how private-sector physicians engaged in contract research describe their professional identities. METHODS AND FINDINGS: We conducted a qualitative study in 2003-2004 combining observation at 25 private-sector research organizations in the southwestern United States and 63 semi-structured interviews with physicians, research staff, and research participants at those clinics. We used grounded theory to analyze and interpret our data. The 11 private-sector physicians who participated in our study reported becoming principal investigators on industry clinical trials primarily because contract research provides an additional revenue stream. The physicians reported that they saw themselves as trial practitioners and as businesspeople rather than as scientists or researchers. CONCLUSIONS: Our findings suggest that in addition to having financial motivation to participate in contract research, these US private-sector physicians have a professional identity aligned with an industry-based approach to research ethics. The generalizability of these findings and whether they have changed in the intervening years should be addressed in future studies. Please see later in the article for the Editors' Summary.

    Hypertension is a public health problem due to its high prevalence and long-term cardiovascular complications. In Brazil in 2005, cardiovascular diseases were responsible for 28% of all deaths. Efforts are being made within primary care to achieve adequate hypertension control. The Family Health Program (FHP) has the aims of promoting quality of life and intervening in factors that put this at risk. The objective of this study was to evaluate the rate of blood pressure control among patients followed up at FHP units compared with those at primary healthcare units (PHUs). Analytical cross-sectional study in the municipality of Petrópolis, Rio de Janeiro, from January to December 2005. Five hundred patients with a diagnosis of hypertension were included: 250 were being followed up at two FHP units and 250 at two PHUs. The diagnosis of hypertension was based on the Fourth Brazilian Hypertension Consensus, and the patients needed to have been under follow-up at the units for at least 12 months. Patients' blood pressure was considered to be under control if it was less than 140/90 mmHg at the last consultation. Blood pressure was under control in 29.2% (n = 73) at FHP units and 39.23% (n = 98) at PHUs (odds ratio = 0.64; confidence interval = 0.44-0.93; P = 0.024). Blood pressure control was better among patients followed up at PHUs than among those followed up at FHP units.

    Over the past 10 years, there has been significant fluctuation in the yearly growth rates for cosmetic surgery procedures in both the United States and the United Kingdom. The authors compare cosmetic surgical procedure rates in the United Kingdom and United States with the macroeconomic climate of each region to determine whether there is a direct relationship between cosmetic surgery rates and economic health. The authors analyzed annual cosmetic surgery statistics from the British Association of Aesthetic Plastic Surgeons and the American Society for Aesthetic Plastic Surgery for 2002-2011 against economic indices from both regions, including the gross domestic product (GDP), consumer prices indices (CPI), and stock market reports. There was a 285.9% increase in the United Kingdom and a 1.1% increase in the United States in the number of procedures performed between 2002 and 2011. There were significant positive correlations between the number of cosmetic procedures performed in the United Kingdom and both the GDP (r = 0.986, P correlation (r = -0.668, P correlation. Data from the United States and United Kingdom suggest 2 very different growth patterns in the number of cosmetic surgeries being performed as compared with the economy in each region. Economic indices are accurate indicators of numbers of procedures being performed in the United Kingdom, whereas rates in the United States seem independent of those factors.

    Groundwater quality in the approximately 1,500 square-mile Mojave (MOJO) study unit was investigated from February to April 2008, as part of the Priority Basin Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The GAMA Priority Basin Project was developed in response to the Groundwater Quality Monitoring Act of 2001 and is being conducted by the U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (SWRCB). MOJO was the 23rd of 37 study units to be sampled as part of the GAMA Priority Basin Project. The MOJO study was designed to provide a spatially unbiased assessment of the quality of untreated ground water used for public water supplies within MOJO, and to facilitate statistically consistent comparisons of groundwater quality throughout California. Samples were collected from 59 wells in San Bernardino and Los Angeles Counties. Fifty-two of the wells were selected using a spatially distributed, randomized grid-based method to provide statistical representation of the study area (grid wells), and seven were selected to aid in evaluation of specific water-quality issues (understanding wells). The groundwater samples were analyzed for a large number of organic constituents [volatile organic compounds (VOCs), pesticides and pesticide degradates, and pharmaceutical compounds], constituents of special interest (perchlorate and N-nitrosodimethylamine [NDMA]) naturally occurring inorganic constituents (nutrients, dissolved organic carbon [DOC], major and minor ions, silica, total dissolved solids [TDS], and trace elements), and radioactive constituents (gross alpha and gross beta radioactivity, radium isotopes, and radon-222). Naturally occurring isotopes (stable isotopes of hydrogen, oxygen, and carbon, stable isotopes of nitrogen and oxygen in nitrate, and activities of tritium and carbon-14), and dissolved noble gases also were measured to help identify the sources and ages of the sampled

The median length of stay (LOS was 2 days while mean LOS was half a day longer in the 2013 Cohort. None of our patients required intubation, and there was no mortality. Conclusion: We observed slight shift toward older age, considerably increased the rate of PICU admission, increased utilization of Ipratropium bromide, magnesium sulfate, and NIV as important modalities of treatment.

  10. Tires as habitats for mosquitoes: a review of studies within the eastern United States.

    2008-07-01

    Discarded vehicle tires are a common habitat for a variety of container mosquito species. I reviewed the literature from the last 50 yr on mosquitoes collected within tires in the eastern United States with four objectives: to examine the historical and contemporary issues of tires as a habitat for mosquitoes, to identify tire-inhabiting species, to summarize findings from studies that focused on biotic and abiotic characteristics of tires, and to offer future directions to aid our understanding of tire-inhabiting mosquitoes. Thirty-two species have been documented, including seven invasives, with the most frequently encountered being Aedes triseriatus, Ae. albopictus, Ae. atropalpus, Culex restuans, Cx. pipiens, Cx. territans, Anopheles punctipennis, and Toxorhynchites rutilus. The proclivity of these species to occupy small containers is one possible explanation for their occurrence in tires. The native species Ae. triseriatus was abundant and the most often collected, particularly in central and northern regions, whereas the invasive Ae. albopictus was most abundant in the south. One half of the studies investigating aspects of the tire environment compared mosquito populations between sunlit and shaded tires, with the general finding that this factor alone led to dramatic differences in larval species composition and abundance patterns. Less frequently investigated factors, e.g., tire orientation, detritus, and proximity to humans, also were found to affect patterns of occupancy by mosquitoes. For the future, I suggest more surveys are needed in understudied areas, as well as quantitative experiments to determine habitat associations and community dynamics in tires, which are especially necessary to assist in understanding invasions. Discarded tires are important for studies of vector dynamics, because of their abundance near human populations and because they expand the habitat range of mosquitoes that vector pathogens.

    Full Text Available INTRODUCTION: An aeromycological study verifies the presence and quantifies the concentration of fungal propagules in the air. It is very important in the hospital setting because of the increasing numbers of immunosuppressed and severely ill patients. The objective of this study was to determine the concentration of fungi in the air of the intensive care unit (ICU of "Dr. Manuel Gea González" General Hospital. METHODS: This is a descriptive, observational cross-sectional study. Air samples were obtained with a single stage Thermo-Andersen Viable Particle Sampler (Thermo Electron Corporation -Massachusetts, U.S.A. in a Petri dish with potato dextrose agar for 15 minutes at two different times (morning and afternoon and heights (1 and 1.5 meters. The Petri dishes were incubated for five to seven days at 27ºC, the number of colonies was counted, and the total CFU/m³ was determined. The isolated fungal genera were identified by morphological features. Epi Info v. 3.4.3 © was used for statistical analysis. RESULTS: The mean concentration of fungi in the air of the ICU was 85.08 ± 29.19 CFU/m³; while in the outside air it was 84.3 ± 17.23 CFU/m³ (p = 0.96. The fungi isolated were: Cladosporium spp., Penicillium spp., Aspergillus spp. (non-fumigatus, Fusarium spp., Exophiala spp., Syncephalastrum spp., and Acremonium spp. DISCUSSION: Fungal spores were found in the air of the ICU and Cladosporium spp. was the most frequently isolated fungi. There was no difference according to sampling time or height.

    Hospitalisation of a child in a paediatric intensive care unit (PICU) involves major stress for parents. They wish to stay at their child's bedside while at the same time giving the usual attention to their other children. The resultant out-of-pocket expenses have rarely been studied. Over a 6-month period all the families of children hospitalised in our PICU for more than 4 days, speaking French and insured by our social security system, were eligible for inclusion. Participation was proposed only after diagnosis, treatment and prognosis had been determined. Costs were retrieved from a diary list of customised items and computed as the amount in excess of usual expenses until the end of the hospital stay. 117 children were hospitalised in our PICU for a total of 131 stays. The families of 16 fulfilled the inclusion criteria. One dropped out after a week at the parents' request. The children's age was 2.9 +/- 3.8 years and 67% were male. The majority had malformations (53%) or infections (33%). The total length of stay was 49 +/- 51 days, of which 24 +/- 41 were spent in the PICU. On average, parents spent CHF 86 +/- 31 every day, mainly on travel and meals. Over the entire hospital stay their expenses amounted to CHF 4,078 +/- 4,552. Direct out-of-pocket expenses for parents of children hospitalised in the PICU are considerable. Improvement in the social security system may be necessary to address this issue.

    It is assumed that there is a relation between light exposure and delirium incidence. The aim of our study was to determine the effect of prehospital light exposure on the incidence of intensive care unit (ICU)-acquired delirium. Data from 3 ICUs in the Netherlands were analyzed retrospectively. Delirium was assessed with the Confusion Assessment Method for the ICU. Daily light intensity data were obtained from meteorological stations in the vicinity of the 3 hospitals. The association between light intensity and delirium incidence was analyzed using logistic regression analysis adjusting for known covariates for delirium. Data of 3198 patients, aged (mean ± SD) 61.9 ± 15.3 years with Acute Physiology and Chronic Health Evaluation II score 16.4 ± 6.6 were analyzed. Delirium incidence was 31.2% and did not vary significantly throughout the year. Twenty-eight-day preadmission photoperiod was highest in spring and lowest in winter; however, no association between light exposure and delirium incidence was found (odds ratio, 1.00; 95% confidence interval, 0.99-1.00; P = 0.72). Furthermore, delirium was significantly associated with age, infection, use of sedatives, Acute Physiology and Chronic Health Evaluation II score, and diagnosis of neurological disease or trauma. The incidence of delirium does not differ per season and prior sunlight exposure does not play a role of importance in the development of ICU-acquired delirium. Copyright © 2014 Elsevier Inc.

    This study aimed to describe and explain teamwork and factors that influence team processes in everyday practice in an intensive care unit (ICU) from a staff perspective. The setting was a Swedish ICU. Data were collected from 38 ICU staff in focus groups with registered nurses, assistant nurses, and anaesthetists, and in one individual interview with a physiotherapist. Constant comparative analysis according to grounded theory was conducted, and to identify the relations between the emerged categories, the paradigm model was applied. The core category to emerge from the data was "balancing intertwined responsibilities." In addition, eleven categories that related to the core category emerged. These categories described and explained the phenomenon's contextual conditions, causal conditions, and intervening conditions, as well as the staff actions/interactions and the consequences that arose. The findings indicated that the type of teamwork fluctuated due to circumstantial factors. Based on the findings and on current literature, strategies that can optimise interprofessional teamwork are presented. The analysis generated a conceptual model, which aims to contribute to existing frameworks by adding new dimensions about perceptions of team processes within an ICU related to staff actions/interactions. This model may be utilised to enhance the understanding of existing contexts and processes when designing and implementing interventions to facilitate teamwork in the pursuit of improving healthcare quality and patient safety.

    This document is the combined Remedial Investigation and Feasibility Study Report for the lower Watts Bar Reservoir (LWBR) Operable Unit (OU). The LWBR is located in Roane, Rhea, and Meigs counties, Tennessee, and consists of Watts Bar Reservoir downstream of the Clinch river. This area has received hazardous substances released over a period of 50 years from the US Department of Energy`s Oak Ridge Reservation (ORR), a National Priority List site established under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). As required by this law, the ORR and all off-site areas that have received contaminants, including LWBR, must be investigated to determine the risk to human health and the environment resulting from these releases, the need for any remedial action to reduce these risks, and the remedial actions that are most feasible for implementation in this OU. Contaminants from the ORR are primarily transported to the LWBR via the Clinch River. There is little data regarding the quantities of most contaminants potentially released from the ORR to the Clinch River, particularly for the early years of ORR operations. Estimates of the quantities released during this period are available for most radionuclides and some inorganic contaminants, indicating that releases 30 to 50 years ago were much higher than today. Since the early 1970s, the release of potential contaminants has been monitored for compliance with environmental law and reported in the annual environmental monitoring reports for the ORR.

    Vertical sputtering systems are key equipment in the manufacture of liquid crystal display (LCD) panels. During the sputtering process for LCD panels, a glass plate is transported between chambers for various processes, such as deposition of chemicals on the surface. The minimization of surface scratches and damage to the glass, the rate of consumption of gas, and the stability of the floating glass-plate are key considerations in the design of a gas pad. To develop new, non-contact systems of transportation for large, thin glass plates, various shapes of the nozzle of a gas pad unit were considered in this study. In the proposed nozzle design, negative pressure was used to suppress undesirable fluctuations of the glass plate. After the nozzle's shape was varied through numerical simulations in two dimensions, we determined the optimal shape, after which three-dimensional analyses were carried out to verify the results from the two-dimensional analyses. The rate of heat transfer from the glass plate, as a result of the gas jet, was also investigated. The average Nusselt number at the glass surface varied from 22.7 to 26.6 depending on the turbulence model, while the value from the correlation for the jet array was 23.5. It was found that the well-established correlation equation of the Nusselt number for the circular jet array can be applied to the cooling of the glass plates

    In order to estimate the role of laminar flow of viscous, aromatic matter of carbonaceous precursor on microtextural preorientation in pregraphitization stage, we performed experiments with coal tar pitch (CTP). The principal hypothesis of preorientation of basic structural units (BSUs) in the case of laminar flow (pressure impregnation of CTP into porous matrix) and secondary release of volatiles during carbonization were studied. Glass microplates, planar porous medium with average distance between single microplates 5 μm were used as suitable porous matrix. Samples of CTP were carbonized up to 2500 °C. Optical microscopy reveals large flow domains in the sample of cokes carbonized between glass microplates. Raman microspectroscopy and high resolution transmission electron microscopy (HRTEM) show that at nanometric scale, the samples do not support the proposed hypotheses. With increasing temperature of pyrolysis, the graphitization of CTP impregnated into porous matrix proceeds to lower degree of structural ordering in comparison with single pyrolyzed CTP. This is explained by the release of volatile matter during carbonization in geometrically restricted spaces. More evident structural changes were discovered with the sample of single coke, where parts of fine grain mosaics, relicts of 'so called QI parts', reveal higher structural organization, in comparison with large and prolonged flow domains, similar to flow domains of cokes from microplates.

    Poly(p-fluoranthenevinylenes) and their dithiocarbamate precursors have been deposited on indium-tin oxide electrodes and electrochemical properties of the obtained films have been investigated by means of cyclic voltammetry studies in acetonitrile solutions containing 0.1 M (n-C{sub 4}H{sub 9}){sub 4}NBF{sub 4} as supporting electrolyte. It has been found that all investigated polymers display well pronounced n-doping processes. Electrochemical reduction of the dithiocarbamate precursors seems to be associated with C-S bond cleavage with elimination of -SC(S)N(C{sub 2}H{sub 5}){sub 2} group. In view of UV-vis spectroscopic data the obtained products, tentatively identified as polymers containing fluoranthene units connected by -CH{sub 2}-CH{sub 2}- bridges, are somewhat less conjugated than the corresponding poly(p-fluoranthenevinylenes). Reversible electrochemical reduction of poly(p-fluoranthenethanes) occurs at potentials only somewhat (ca. 0.1 V) more negative as found for their poly(p-fluoranthenevinylenes) analogues suggesting relatively weak coupling between fluoranthene kernels in both kinds of investigated polymers.

    This article describes a study that evaluated the quality of teamwork in a surgical intensive care unit and assessed whether teamwork could be improved significantly through a tailor-made intervention. The quality of teamwork prior to and after the intervention was assessed using the Interprofessional Practice and Education Quality Scales (IPEQS) using the PROSE online diagnostics and documenting system, which assesses three domains of teamwork: organisational factors, care processes, and team members' attitudes and beliefs. Furthermore, team members evaluated strengths and weaknesses of the teamwork through open-ended questions. Information gathered by means of the open questions was used to design a tailor-made 12-week intervention consisting of (1) optimising the existing weekly interdisciplinary meetings with collaborative decision-making and clear communication of goal-oriented actions, including the psychosocial aspects of care; and (2) organising and supporting the effective exchange of information over time between all professions involved. It was found that the intervention had a significant impact on organisational factors and care processes related to interprofessional teamwork for the total group and within all subgroups, despite baseline differences between the subgroups in interprofessional teamwork. In conclusion, teamwork, and more particularly the organisational aspects of interprofessional collaboration and processes of care, can be improved by a tailor-made intervention that takes into account the professional needs of healthcare workers.

    Hemodialysis (HD) catheters are commonly used as temporary vascular access in patients with kidney failure who require immediate HD. The use of these catheters is limited by complications such as infections, thrombosis resulting in poor blood flow. We studied the complications and outcomes of nontunneled catheters used for vascular access in our dialysis unit. The records of all patients, with renal failure who were dialyzed over a two-year period and had a double lumen nontunneled catheter inserted, were retrieved. Catheter insertion was carried out under ultrasound guidance using the modified Seldinger technique. The demographic data of patients, etiology of chronic kidney disease, and complications and outcomes of these catheters were noted. Fifty-four patients with mean age 43.7 ± 15.8 years had 69 catheters inserted for a cumulative total of 4047 catheter-days. The mean catheter patency was 36.4 ± 37.2 days (range: 1-173 days). Thrombosis occluding the catheters was the most common complication and occurred in 58% of catheters leading to catheter malfunction, followed by infections in18.8% of catheters. During follow-up, 30 (43.5%) catheters were removed, 14 (20.3%) due to catheter malfunction, eight (11.6%) due to infection, five (7.2%) elective removal, and three (4.3%) due to damage. Thrombotic occlusion of catheters was a major limiting factor to the survival of HD catheters. Improvement in catheter patency can be achieved with more potent lock solutions.

    The time of admission to a hospital, especially when unplanned, has been reported as the most stressful moment of hospitalization for both parents and children (Odievre, 2001). This qualitative study explored parents and hospital staff's perceptions and experiences related to the process of admission to a pediatric unit. Focus groups, two with parents (total n = 12) and one with health care professionals (n = 6), were conducted, and content analysis inspired by Graneheim and Lundman (2004) was performed. Parents identified four categories of perceptions: 1) management of an uncertain situation at the time of admission, 2) feelings related to the child's illness, 3) parent perception of professional's performance, and 4) parent experience of their role. Health care professionals identified two categories: 1) hospital admission as a continuous care process, and 2) undertaking improvements in the admission process. A common theme emerged about the importance of parents' trust in professionals in order to build a therapeutic relationship. Findings underscore the need for strategies to improve the hospital pediatric admission process based on a parent-professional relationship of trust and confidence through continuous quality communication and support. These strategies would include providing a nurse in charge of the admission process to assure continuity of care throughout the child's hospitalization.

    Measurements of extremely low frequency electromagnetic fields and low frequency magnetic fields emitted by a set of video display terminal (VDT) units are reported. The field values measured at the position normally occupied by the user are below the safety limits. This is because the field amplitudes decrease rapidly (following a 1/R3 law) with the distance from the source, as has been verified in this work. Measurements with a commercial shielding device consisting of small plastic balls filled with a water solution of rare earth elements were also performed. The only physical mechanism that could be hypothesized to produce an active suppression of the VDT field is that rare earth atoms, which probably were chosen due to their large magnetic moment, behave as oscillating magnetic dipoles capable of emitting a secondary magnetic field that, along some particular directions, has a phase that is opposite to that of the exciting field. Unfortunately, if one analyzes this mechanism quantitatively, it is easy to show that the secondary magnetic field is absolutely negligible, as was confirmed by experimental measurements performed in this study.

    Full Text Available Abstract Background The purpose of this exploratory study was to examine Cambodian refugee mothers' infant feeding beliefs, practices, and decision making regarding infant feeding in the U.S. and to explore if a culturally-specific breastfeeding program is appropriate for this community. Methods A self-administered questionnaire and a 30 minute in-person interview were used to collect information from nine women. The audio-taped interviews were transcribed, answers compiled, and themes from each question identified. Results All participants practiced either traditional Cambodian diet (pregnancy and postpartum diet including, tnam sraa, herbs mixed with either wine or tea, traditional Cambodian rituals (like spung, amodified sauna or both, despite having lived in the U.S. for many years. All nine women initiated breastfeeding, however eight women introduced infant formula while in hospital. Perceived low milk supply and returning to work were the main reasons cited for partial breastfeeding and early cessation of breastfeeding. Conclusion While causes of initiation of other foods are similar to those found in the U.S. as a whole, a culturally-specific Cambodian breastfeeding support program may help overcome some breastfeeding problems reported by Cambodian refugee mothers who have immigrated to the United States.

    Pattern of endocrine changes in moderate to severely ill patients in a medical intensive care unit, correlation with the severity of illness and whether these changes can predict outcome of the critically ill patients were evaluated and studied in 80 patients admitted with acute physiology and chronic health evaluation (APACHE) II score >10 and without any pre-existing endocrinopathies or on drugs likely to affect the endocrine axis. Adrenal insufficiency was present in 45%, and mortality was higher in those with lower (30 microg/dl) serum cortisol. Sick euthyroid syndrome was detected in 80%, and those with low mean T3 (<0.6 ng/ml), free T4 (<0.89 ng/dl) and total T4 (<4 microg/dl) and had increased mortality. Hypotestosteronaemia was found in 92% of men and was significantly associated with severity of illness in men. Though prolactin is the first hormone to be elevated, there was no correlation between prolactin and severity of illness or mortality.

  5. Host and guest: an applied hermeneutic study of mental health nurses' practices on inpatient units.

    The metaphor of host and guest has value for exploring the practice and role identity of nurses on inpatient mental health units. Two complementary texts, one from the ancient Zen record of Lin-chi, and the other from the contemporary hermeneutic philosopher Richard Kearney, are used to elaborate meanings of host and guest that can be applied to the situation of mental health nurses. In a doctoral study with a hermeneutic design, I addressed the topic of nurse-patient relationship using an interpretive framework that included sources from Buddhist thought. The positions of host and guest emerged from interviews with nurses as one interpretive theme to open up new understanding of the topic. The two texts, originally distant in era and culture, both employ the host and guest metaphor. They are applied to extracts from interviews to open up discussions of hierarchy, status, patients' perspectives, otherness and resistances as features of nurses' complex experience. These provide insights into understanding practice and suggest implications for how institutional environments shape practice. An intercultural reading of texts can provide a source of new understanding of nurse-patient relationships. © 2014 John Wiley & Sons Ltd.

    The two three-dimensional oxo-bridged lanthanides {[Ln2 (C4H2O4)3 (H2O)4]· 3H2O}3x,with Ln=Ho3+ (1); Gd3-(2),are isomorphous.They have layer-type structures built up from non-centrosymmetric dinuclear unit Ln2O12(H2O)4,beside three lattice H2O molecules stabilizing the 3D open-framework.The building entities are linked through one classical syn-anti μ2-carboxylato-κ1O:κ1O' bridge.Within the bi-polyhedra,two double μ2-O'; K2O,O' bridges and a syn-syn classical one,support the magnetic measurements carried out on holmium compound indicating relatively weak anti-ferromagnetic interactions.The comparison with magnetic studies on the almost similar reported Gd(Ⅲ) compound,suggested that concomitant antiferromagnetic and ferromagnetic properties could not be excluded.The two distinct thermal behaviors evidenced the higher metal-water bond strength with the smaller cation,and revealed the great supramolecular effects generated by hydrogen-bonding patterns.

    Objective Psychological and physical health are often conceptualized as the absence of disease, but less research addresses positive psychological and physical functioning. For example, optimism has been linked with reduced disease risk and biological dysfunction, but very little research has examined associations with markers of healthy biological functioning. Thus, we investigated the association between two indicators of positive health: optimism and serum antioxidants. Methods The cross-sectional association between optimism and antioxidant concentrations was examined in 982 men and women from the Midlife in the United States study. Primary measures included self-reported optimism (assessed with the revised Life Orientation Test) and serum concentrations of nine different antioxidants (carotenoids and Vitamin E). Regression analyses examined the relationship between optimism and antioxidant concentrations in models adjusted for demographics, health status, and health behaviors. Results For every standard deviation increase in optimism, carotenoid concentrations increased by 3–13% in age-adjusted models. Controlling for demographic characteristics and health status attenuated this association. Fruit and vegetable consumption and smoking status were identified as potential pathways underlying the association between optimism and serum carotenoids. Optimism was not significantly associated with Vitamin E. Conclusions Optimism was associated with greater carotenoid concentrations and this association was partially explained by diet and smoking status. The direction of effects cannot be conclusively determined. Effects may be bidirectional given that optimists are likely to engage in health behaviors associated with more serum antioxidants, and more serum antioxidants are likely associated with better physical health that enhances optimism.

    2013-01-01

    Food misdescription has become of paramount importance as consumers come into contact daily with a great variety of foods. The controversies surrounding genetically modified organism (GMO) labelling and malpractices in the food chain have forced regulatory authorities to authenticate food from production to consumption. This paper reports the results of a surveillance programme conducted in the United Arab Emirates (UAE) market to assess the status of food misdescription and authenticity. A DNA test was used to screen random samples of processed meat products bought from supermarkets in the UAE. A total of 246 samples were analysed from different geographical locations. The majority of samples showed a high standard of legal compliance, with over 95% confirmed for authenticity. However, 5% of samples were found to contain undeclared species. In conclusion, this study confirms the presence of undeclared food in the UAE market. Regular surveillance and monitoring programmes along with strict implementation of the Food and Adulteration Act may alleviate misdescription issues to a greater extent.

  9. A novel in vitro model to study pericytes in the neurovascular unit of the developing cortex.

    Christoph M Zehendner

    Full Text Available Cortical function is impaired in various disorders of the central nervous system including Alzheimer's disease, autism and schizophrenia. Some of these disorders are speculated to be associated with insults in early brain development. Pericytes have been shown to regulate neurovascular integrity in development, health and disease. Hence, precisely controlled mechanisms must have evolved in evolution to operate pericyte proliferation, repair and cell fate within the neurovascular unit (NVU. It is well established that pericyte deficiency leads to NVU injury resulting in cognitive decline and neuroinflammation in cortical layers. However, little is known about the role of pericytes in pathophysiological processes of the developing cortex. Here we introduce an in vitro model that enables to precisely study pericytes in the immature cortex and show that moderate inflammation and hypoxia result in caspase-3 mediated pericyte loss. Using heterozygous EYFP-NG2 mouse mutants we performed live imaging of pericytes for several days in vitro. In addition we show that pericytes maintain their capacity to proliferate which may allow cell-based therapies like reprogramming of pericytes into induced neuronal cells in the presented approach.

    2015-10-01

    We replicated Son, Ellis, and Yoo (2013) and extended Ellis et al.'s (2014) taxonomy of harmful and inadequate supervision by providing and testing cross-national comparative descriptive data about clinical supervision practices in the Republic of Ireland versus the United States. Participants were 149 Republic of Ireland and 151 U.S. mental health supervisees currently receiving clinical supervision. The results suggested that characteristics of supervision in the Republic of Ireland and United States evidenced both similarities and differences. The dissimilar credentialing systems appeared to account for the observed differences, suggesting that Ellis et al.'s (2014) criteria for inadequate supervision need to be modified to account for country-specific standards for supervision. Unexpectedly, no significant differences were observed between the Republic of Ireland and United States in the high occurrence of inadequate, harmful, or exceptional supervision. The results suggested that 79.2% (Republic of Ireland) and 69.5% (United States) of the supervisees were categorized as currently receiving inadequate supervision, and 40.3% (Republic of Ireland) and 25.2% (United States) of the supervisees as receiving harmful supervision. At some point in their careers, 92.4% (Republic of Ireland) and 86.4% (United States) of the supervisees received inadequate supervision--51.7% (Republic of Ireland) and 39.7% (United States) received harmful supervision. On the positive side, 51.0% (Republic of Ireland) and 55.0% (United States) of the supervisees reported receiving exceptional supervision from their current supervisors. Substantial discrepancies were observed between supervisees' perceptions versus more objective criteria of the inadequate or harmful supervision they received. Implications for cross-national supervision research and training are discussed.

    Full Text Available Background: Epidemiological studies have shown that employees working with visual display units (VDU are more likely to complain about musculoskeletal disorders (MSDs. The aim of this study has been to evaluate associations among MSDs and individuals and work-related factors. Material and Methods: A total of 1032 VDU workers were assessed about their personal (i.e., age, working history, smoking history, physical activity and work-related factors (i.e., predominant job tasks performed, work posture. Work environment was evaluated regarding fulfillment of the standard ISO 9241-5:1998. The investigation required a direct observation of participants (in order to accurately assess the prevalence of MSDs and workstations. Adjusted odds ratios (ORa were calculated by means of the logistic regression model. Results: Prevalence of MSDs was relatively high (53%. In general, MSDs were significantly associated with female sex (OR = 2.832, 95% confidence interval (CI: 2.178–3.683, age ≥ 50 years old (OR = 2.231, 95% CI: 1.236–4.026, longer exposure to VDU, both as working history (10–14 years: OR = 1.934, 95% CI: 1.301–2.875; ≥ 15 years: OR = 2.223, 95% CI: 1.510–3.271 and working time (30–39 h/week: OR = 1.537, 95% CI: 1.087–2.273. Inappropriate workstation design was confirmed by the multivariate analysis as a risk factor for MSDs (ORa = 2.375, 95% CI: 1.124–5.018. Conclusions: Musculoskeletal disorders were significantly associated with individual factors as well as characteristics of work environment. An appropriate design of workstations may significantly reduce their prevalence amongst VDU workers. Med Pr 2016;67(6:707–719

    Full Text Available Abstract Background Although Western models of education are being used to establish health professional programs in non-Western countries, little is known about how students in these countries perceive their learning experiences. The purpose of this qualitative study was to describe the reflections of physiotherapy students from a Middle East culture during their clinical placements and to compare them to reflections of physiotherapy students from a Western culture. Methods Subjects were six senior students (3 females, 3 males, mean age 22.6 years and 15 junior, female students (mean age 20.1 years in the baccalaureate physiotherapy program at a university in the United Arab Emirates (UAE. They wrote weekly entries in a journal while in their clinical placements. They described an event, their reaction to it, and how it might affect their future behavior. Two evaluators independently read and coded the content of all the journals, and then worked together to categorize the data and develop themes. A third evaluator, an UAE national, independently read the journals to validate the content analysis. A feedback session with students was used to further validate the data interpretation. The themes were compared to those derived from a similar study of Canadian physiotherapy students. Results The content of the students' reflections were grouped into 4 themes: professional behavior, awareness of learning, self-development and shift to a patient orientation, and identification and analysis of ethical issues. Although the events were different, students from the UAE considered many of the same issues reflected on by Canadian students. Conclusion Physiotherapy students from a Middle East culture consider many of the same issues as students from a Western culture when asked to reflect on their clinical experience. They reflect on their personal growth, on how they learn in a clinical setting, and on the ethical and professional behaviors of themselves

    Intensive care unit (ICU) nurses are at increased risk of developing psychological problems including posttraumatic stress disorder (PTSD). However, there are resilient individuals who thrive and remain employed as ICU nurses for many years. The purpose of this study was to identify mechanisms employed by highly resilient ICU nurses to develop preventative therapies to obviate the development of PTSD in ICU nurses. Qualitative study using semi-structured telephone interviews with randomly selected ICU nurses in the USA. Purposive sampling was used to identify ICU nurses who were highly resilient, based on the Connor-Davidson Resilience Scale and those with a diagnosis of PTSD, based on the posttraumatic diagnostic scale. New interviews were conducted until we reached thematic saturation. Thirteen highly resilient nurses and fourteen nurses with PTSD were interviewed (n = 27). A constructivist epistemological framework was used for data analysis. Differences were identified in four major domains: worldview, social network, cognitive flexibility, and self-care/balance. Highly resilient nurses identified spirituality, a supportive social network, optimism, and having a resilient role model as characteristics used to cope with stress in their work environment. ICU nurses with a diagnosis of PTSD possessed several unhealthy characteristics including a poor social network, lack of identification with a role model, disruptive thoughts, regret, and lost optimism. Highly resilient ICU nurses utilize positive coping skills and psychological characteristics that allow them to continue working in the stressful ICU environment. These characteristics and skills may be used to develop target therapies to prevent PTSD in ICU nurses.

    Full Text Available Abstract Background Despite the substantial progress in the quality of critical care, the incidence and mortality of acute kidney injury (AKI continues to rise during hospital admissions. We conducted a national, multicenter, prospective, epidemiological survey to evaluate the importance of AKI in intensive care units (ICUs in Hungary. The objectives of this study were to determine the incidence of AKI in ICU patients; to characterize the differences in aetiology, illness severity and clinical practice; and to determine the influencing factors of the development of AKI and the patients' outcomes. Methods We analysed the demographic, morbidity, treatment modality and outcome data of patients (n = 459 admitted to ICUs between October 1st, 2009 and November 30th, 2009 using a prospectively filled in electronic survey form in 7 representative ICUs. Results The major reason for ICU admission was surgical in 64.3% of patients and medical in the remaining 35.7%. One-hundred-twelve patients (24.4% had AKI. By AKIN criteria 11.5% had Stage 1, 5.4% had Stage 2 and 7.4% had Stage 3. In 44.0% of patients, AKI was associated with septic shock. Vasopressor treatment, SAPS II score, serum creatinine on ICU admission and sepsis were the independent risk factors for development of any stage of AKI. Among the Stage 3 patients (34 50% received renal replacement therapy. The overall utilization of intermittent renal replacement therapy was high (64.8%. The overall in-hospital mortality rate of AKI was 49% (55/112. The ICU mortality rate was 39.3% (44/112. The independent risk factors for ICU mortality were age, mechanical ventilation, SOFA score and AKI Stage 3. Conclusions For the first time we have established the incidence of AKI using the AKIN criteria in Hungarian ICUs. Results of the present study confirm that AKI has a high incidence and is associated with high ICU and in-hospital mortality.

    Air pollution in the workplace environment due to industrial operation have been found to cause serious occupational health hazard. Similarly, heat stress is still most neglected occupational hazard in the tropical and subtropical countries like India. The hot climate augments the heat exposure close to sources like furnaces. In this study an attempt is made to assess air pollution and heat exposure levels to workers in the workplace environment in glass manufacturing unit located in the State of Gujarat, India. Samples for workplace air quality were collected for SPM, SO(2), NO(2) and CO(2) at eight locations. Results of workplace air quality showed 8-hourly average concentrations of SPM: 165-9118 microg/m(3), SO(2): 6-9 microg/m(3) and NO(2): 5-42 microg/m(3), which were below the threshold limit values of workplace environment. The level of CO(2) in workplace air of the plant was found to be in the range 827-2886 microg/m(3), which was below TLV but much higher than the normal concentration for CO(2) in the air (585 mg/m(3)). Indoor heat exposure was studied near the furnace and at various locations in an industrial complex for glass manufacturing. The heat exposure parameters including the air temperature, the wet bulb temperature, and the globe parameters were measured. The Wet Bulb Globe Temperature (WBGT), an indicator of heat, exceeded ACGIH TLVs limits most of the time at all the locations in workplace areas. The recommended duration of work and rest have also been estimated.
