    Norms and guidelines are formed for safe disposal of hospital waste but question is whether these guidelines are being followed and if so, to what extent. Hence, this study was conducted with objective to study the knowledge and practices about hospital waste disposal and universal safety precautions in class IV employee and to study its relationship with education, occupation and training. A cross-sectional study was carried out in a teaching hospital in Mumbai using semi-structured questionnaire in which Class IV employee were included. Questionnaire was filled by face to face interview. Data were analyzed using SPSS. 48.7% Class IV employee were not trained. More than 40% were following correct practices about disinfection of infectious waste. None of the respondents were using protective footwear while handling hospital waste. Only 25.5% were vaccinated for hepatitis B. 16% had done HIV testing due to contact with blood, body fluid, needle stick injury. Knowledge and practices about hospital waste disposal and universal precaution were statistically significant in trained respondents. Training of employees should be given top priority; those already in service should be given on the job training at the earliest.

    Full Text Available A desinfecção de todo e qualquer molde obtido é medida de biossegurança obrigatória na atividade clínica. Tão importante quanto a desinfecção é a seleção do método e da solução desinfetante a ser utilizada para cada material de moldagem. É imperativo que a capacidade de reprodução de detalhes, a estabilidade dimensional e o grau de umedecimento (ou "molhabilidade" não sejam criticamente afetados. O propósito deste trabalho foi avaliar o grau de umedecimento de uma marca comercial de poliéter (Impregum F por três diferentes marcas comerciais de gesso tipo IV (Herostone, Durone e Polirock, após sua desinfecção por aerossóis de hipoclorito de sódio 1% (líquido de Milton ou glutaraldeído 2% (Glutalabor II. Foram confeccionados 45 moldes de poliéter, os quais, em grupos de 15, receberam aerossóis de água (Grupo Controle, Líquido de Milton ou Glutalabor II. Em seguida, sobre a superfície dos moldes foram confeccionados modelos de gesso tipo IV, em número de 5 para cada marca de gesso. Após seu seccionamento mediano e preparo da superfície de corte, os modelos foram levados ao microscópio Carl Zeiss para leitura do ângulo de contato. Os resultados obtidos permitiram concluir que: a a capacidade de umedecimento do poliéter por diferentes marcas comerciais de gesso tipo IV variou para os gessos estudados; b o gesso Durone adaptou-se melhor aos moldes de poliéter do que os gessos Herostone e Polirock; c a desinfecção dos moldes com aerossóis de hipoclorito de sódio 1% (líquido de Milton ou glutaraldeído 2% (Glutalabor não afetou a adaptação entre os gessos e o poliéter.Impressions carried out in the dental office are potential contamination pathways.

    Full Text Available Background The Acute Physiology and Chronic Health Evaluation (APACHE II model has been widely used in Korea. However, there have been few studies on the APACHE IV model in Korean intensive care units (ICUs. The aim of this study was to compare the ability of APACHE IV and APACHE II in predicting hospital mortality, and to investigate the ability of APACHE IV as a critical care triage criterion. Methods The study was designed as a prospective cohort study. Measurements of discrimination and calibration were performed using the area under the receiver operating characteristic curve (AUROC and the Hosmer-Lemeshow goodness-of-fit test respectively. We also calculated the standardized mortality ratio (SMR. Results The APACHE IV score, the Charlson Comorbidity index (CCI score, acute respiratory distress syndrome, and unplanned ICU admissions were independently associated with hospital mortality. The calibration, discrimination, and SMR of APACHE IV were good (H = 7.67, P = 0.465; C = 3.42, P = 0.905; AUROC = 0.759; SMR = 1.00. However, the explanatory power of an APACHE IV score >93 alone on hospital mortality was low at 44.1%. The explanatory power was increased to 53.8% when the hospital mortality was predicted using a model that considers APACHE IV >93 scores, medical admission, and risk factors for CCI >3 coincidentally. However, the discriminative ability of the prediction model was unsatisfactory (C index <0.70. Conclusions The APACHE IV presented good discrimination, calibration, and SMR for hospital mortality.

    Oral surgery, under intravenous sedation, is carried out on a daily basis at Manchester Dental Hospital. This essay discusses the background of conscious sedation in the dental setting and looks at the compliance of patients (and escorts) when having intravenous sedation. The patient journey, from pre-operative assessment through to treatment is considered. Hospital instructions indicate an obligation for patients to attend with a responsible adult (eighteen or over) who remains with them throughout their treatment, escorts them home,and arranges their care for the next twenty-four hours. By following these instructions the patient should receive optimal care. Two questionnaires were devised and given to patients/escorts to assess their compliance with Manchester Dental Hospital postoperative protocols. 100% compliance was the set standard, with results presented as pie charts. This work began during the undergraduate summer vacation of 2012 and continued over a five-month period. Initial results suggested that compliance was generally good but certain improvements could be made. Suggestions for future development are presented. These aim to give clarity to all patients/escorts and their specific roles in the anticipated treatment.

    Full Text Available Ocorrendo isoladamente, as fraturas da clavícula e as luxações acromioclaviculares são lesões muito comuns. A combinação de uma luxação acromioclavicular e de uma fratura do terço lateral da clavícula não é rara. Entretanto, existem muito poucos casos descritos de luxações acromioclaviculares associadas a fraturas do terço médio da clavícula; aquelas associadas a fraturas do terço medial são ainda mais raras. Nós reportamos o caso de um indivíduo adulto do sexo masculino que sofreu uma luxação acromioclavicular (tipo IV associada a uma fratura extra-articular desviada da extremidade medial da clavícula (grupo 3 de Almann em um acidente ciclístico. O paciente foi tratado na fase aguda com redução aberta e fixação interna das duas lesões. Na avaliação clínica, 12 meses após a cirurgia, o paciente apresentava-se assintomático, com mobilidade ativa e passiva completa, força e resistência normais e simetria das cinturas escapulares. As radiografias e a tomografia computadorizada tridimensional mostravam subluxação posterossuperior persistente da articulação acromioclavicular e consolidação anatômica da fratura clavicular.Fractures of the clavicle and acromioclavicular dislocations are very common injuries when they occur separately. The combination of an acromioclavicular dislocation and a fracture of the lateral third of the clavicle is not rare. However, there are very few reported cases of acromioclavicular dislocations associated with fractures of the middle third of the clavicle; those associated with fractures of the medial third are even rarer. We report the case of an adult male who suffered an acromioclavicular dislocation (type IV associated with a displaced extra-articular fracture of the medial end of the clavicle (Almann group 3 in a cycling accident. The patient was treated during the acute phase with open reduction and internal fixation of the two lesions. At the clinical evaluation 12

    The purposes of this study were to investigate the documentation of the DSM-IV-TR- Criteria A in diagnoses of schizophrenia and to identify the symptoms associated with over diagnosis of schizophrenia. This study involved a retrospective review and analysis of data from case notes. Data of 107 newly diagnosed patients with schizophrenia were keyed in and analyzed using SPSS v 19. The cases were then evaluated for the use of the DSM-IV-TR- Criteria A. Over diagnosis was noted in 37.39% of the patients. Disorganised behaviour (12.5%), affective flattening (12.5%), hallucination (16%) and non-bizarre delusion (18.3%) significantly contributed to the over-diagnosis of schizophrenia. Symptoms such as non-bizarre delusion and hallucination were the most commonly used in over-diagnosing schizophrenia and were statistically significant with p ≤0.05. There was a significant lack of DSM-IV-TR Criteria A among the data documented to diagnose schizophrenia and non-bizarre delusion and hallucination were the most commonly used in over-diagnosing schizophrenia. This key problem needs to be addressed. The reliability of a diagnosis is indispensable and achievable with the proper clinical application of DSM-IV-TR Criteria A. The DSM-IV-TR Criteria have been perceived to be useful and reliable and is most widely used throughout the world.

    Stroke data bank can afford important information regarding risk factors, pathogenesis, prognosis, etc. By means of hospital-based stroke registry, we investigated the risk factors and case-fatality rates in different types of stroke and transient ischemic attack (TIA) patients at the National Taiwan University Hospital in 1995. After excluding ineligible patients, 995 patients aged 1-98 years (575 men and 420 women) were recruited. Men predominated in all age groups for stroke and TIA in general except for cerebral hemorrhage (CH) in patients aged or = 45 years. Of these, 676 (67.9%), 41 (4.1%), 228 (22.9%) and 50 (5%) patients were classified in the categories of cerebral infarction (CI), TIA, CH and SAH, respectively. The CI/CH ratio was 2.96. Hypertension remained one of the most important risk factors for CI, CH and TIA patients. Severe extracranial carotid artery stenosis (> or = 50%) was found in 12% of the CI patients and 27% of the TIA patients, but not found in the CH and SAH patients. Of these patients, the 30-day case-fatality rate was 10.9%, highest in SAH (30%), followed by CH (24.1%) and CI (5.6%). There were 41 in-hospital stroke patients who had significantly higher case-fatality rates than the other stroke patients (PTaiwan, there is a secular trend of increasing CI/CH ratios. These findings in Taiwan were compared with those in other populations, including other Asian, Caucasian and black populations. The CI/CH ratios in Asian populations, including Chinese, Japanese and Korean, were much lower than those in Caucasian and black populations. Dietary, environmental and genetic factors probably play important roles in these differences.

    Full Text Available Investigación de carácter cualitativo, con el objetivo de comprender las experiencias cotidianas de los adolescentes con diabetes tipo 1. Los sujetos del estudio son 14 adolescentes atendidos en una clínica para la diabetes en Fortaleza, Ceará, Brasil, de junio a octubre de 2008. La recolección de los datos se hizo a través de entrevistas semi-estructuradas y se organizaron de acuerdo al análisis de contenido de Morse y Field. Se observó que el descubrimiento de la diabetes fue un momento difícil para los adolescentes debido a los cambios que tuvieron que hacer como el control terapéutico. Hacer una dieta adecuada es muy difícil como consecuencia de estímulos internos y externos a que están sometidos y a las dificultades financieras. Los adolescentes tienen el apoyo de la familia y amigos para su tratamiento diario. Además, les gusta el servicio realizado por los profesionales de salud de la clínica. Sin embargo, hay mucho que mejorar como enfermeras en la valorización de las experiencias de la vida de los adolescentes con diabetes, como la identificación de factores que interfieren en el control metabólico.

    Full Text Available Objetivo: valorar las propiedades psicométricas de la escala de afrontamiento y proceso de adaptación de Roy en población mexicana. Materiales y métodos: la escala se aplicó a 200 participantes con diabetes mellitus tipo 2. Para validar el constructo se realizó la extracción de factores con componentes principales y rotación Varimax, con Eigenvalores por arriba de 1 y cargas de factor mayores a ,30. Resultados: seis reactivos fueron eliminados del análisis por mostrar correlación negativa con la correlación total de la escala. El análisis de componentes principales inicial reveló nueve factores con una variación explicada de 65,29%. Sin embargo, no se consideraron tres factores por contener cada uno de ellos solamente un reactivo. Por tanto, la escala final se acepta con 38 reactivos. El coeficiente de confiabilidad Alfa de Cronbach fue de, 93. Discusión: el análisis reveló seis factores, uno más de lo reportado por Roy, y con mayor variación explicada. Algunos reactivos parecen no ser bien comprendidos por los participantes. Conclusiones: este artículo aporta una aproximación metodológica para explorar la adecuación de un instrumento a una población diferente para la que originalmente fue diseñado. Se concluye que la escala tiene consistencia interna y validez de constructo incipiente, los datos reportados en este estudio deben tomarse en cuenta con cautela. Es conveniente revisar de nuevo los reactivos y adecuarlos a la cultura particular, y probar la escala de nuevo con pacientes con enfermedades crónicas degenerativas a fin de contar con instrumentos culturalmente equivalentes.

    Full Text Available RESUMOObjetivou-se com este trabalho comparar o padrão de crescimento, mediante ajustes das respectivas curvas de crescimento por modelos não lineares, bem como estudar o desenvolvimento de cortes de carcaça em relação ao peso da carcaça em diferentes genótipos de frangos tipo caipira. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor. Foram avaliados os pesos da carcaça, do peito, das coxas, das sobrecoxas, das pernas e das asas das aves abatidas aos 85 dias de idade. Apenas as equações propostas por Gompertz, von Bertalanffy e Logístico atingiram a convergência, e o modelo proposto por von Bertalanffy foi o mais adequado para descrever o crescimento dos genótipos de frangos caipiras. Todos os cortes avaliados apresentaram crescimento tardio em relação ao peso da carcaça em genótipos de frangos tipo caipira.

In the 60s - 70s wave of new hospital building, an emphasis on technology can be seen. It’s time to move from the technology...... focus. It is not enough to consider only the factors of function within architecture, hygiene, economy and logistics. We also need to look at aspects of aesthetics, bringing nature into the building, art, color, acoustics, volume and space as we perceive them.

    Home care services use has been proposed as a means of reducing costs in palliative care by decreasing hospital stay without impacting quality of clinical care; however, little is known about utilization of these services in the time following a terminal cancer diagnosis. To examine disease, patient and healthcare system predictors of hospital stay, and home care services use in metastatic gastric cancer patients. This is a population-based, retrospective cohort study. Chart review and administrative data were linked, using a 26-month time horizon to collect health services data. All patients diagnosed with metastatic gastric cancer in the province of Ontario between 2005 and 2008 were included in the study (n = 1433). Age, comorbidity, tumor location, and burden of metastatic disease were identified as predictors of hospital stay and receipt of home care services. Individuals who received home care services spent fewer days in hospital than individuals who did not (relative risk: 0.44; 95% confidence interval: 0.38-0.51). Patients who interacted with a high-volume oncology specialist had shorter cumulative hospital stay (relative risk: 0.62; 95% confidence interval: 0.54-0.71) and were less likely to receive home care services (relative risk: 0.80; 95% confidence interval: 0.72-0.88) than those who did not. Examining how differences in hospital stay and home care services use impact clinical outcomes and how policies may reduce costs to the healthcare system is necessary. © The Author(s) 2014.

    The transmission of meticillin-resistant Staphylococcus aureus (MRSA) between individual patients is difficult to track in institutions where MRSA is endemic. We investigated the transmission of MRSA where ST22-MRSA-IV is endemic on four wards using demographic data, patient and environmental screening, and molecular typing of isolates. A total of 939 patients were screened, 636 within 72 h of admission (on admission) and 303 >72 h after admission, and 1,252 environmental samples were obtained. Isolates were typed by spa, dru and pulsed-field gel electrophoresis (PFGE) typing. A composite dendrogram generated from the three sets of typing data was used to divide isolates into \\'dendrogram groups\\' (DGs). Ten percent of patients (92\\/939) were MRSA-positive; 7 % (44\\/636) on admission and 16 % (48\\/303) >72 h after admission (p = 0.0007). MRSA was recovered from 5 % of environmental specimens (65\\/1,252). Most isolates from patients (97 %, 85\\/88) and the environment (97 %, 63\\/65) exhibited the ST22-MRSA-IV genotype. Four DGs (DG1, DG4, DG16 and DG17) accounted for 58 % of ST22-MRSA-IV isolates from patients. Epidemiological evidence suggested cross-transmission among 44\\/92 patients (48 %) but molecular typing confirmed probable cross-transmission in only 11 instances (13 %, 11\\/88), with the majority of cross-transmission (64 %; 7\\/11) occurring on one ward. In the setting of highly clonal endemic MRSA, the combination of local epidemiology, PFGE, spa and dru typing provided valuable insights into MRSA transmission.

    Recent Food and Drug Administration (FDA) guidance endorses the use of an early clinical response endpoint as the primary outcome for community-acquired bacterial pneumonia (CABP) trials. While antibiotics will now be approved for CABP, in practice they will primarily be used to treat patients with community-acquired pneumonia (CAP). More importantly, it is unclear how achievement of the new FDA CABP early response endpoint translates into clinically applicable real-world outcomes for patients with CAP. To address this, a retrospective cohort study was conducted among adult patients who received ceftriaxone and azithromycin for CAP of Pneumonia Outcomes Research Team (PORT) risk class III and IV at an academic medical center. The clinical response was defined as clinical stability for 24 h with improvement in at least one pneumonia symptom and with no symptom worsening. A classification and regression tree (CART) was used to determine the delay in response time, measured in days, associated with the greatest risk of a prolonged hospital length of stay (LOS) and adverse outcomes (in-hospital mortality or 30-day CAP-related readmission). A total of 250 patients were included. On average, patients were discharged 2 days following the achievement of a clinical response. In the CART analysis, adverse clinical outcomes were higher among day 5 nonresponders than those who responded by day 5 (22.4% versus 6.9%, P = 0.001). The findings from this study indicate that time to clinical response, as defined by the recent FDA guidance, is a reasonable prognostic indicator of real-world effectiveness outcomes among hospitalized PORT risk class III and IV patients with CAP who received ceftriaxone and azithromycin.

    . Asteroids, like planets, are driven by a great variety of both dynamical and physical mechanisms. In fact, images sent back by space missions show a collection of small worlds whose characteristics seem designed to overthrow our preconceived notions. Given their wide range of sizes and surface compositions, it is clear that many formed in very different places and at different times within the solar nebula. These characteristics make them an exciting challenge for researchers who crave complex problems. The return of samples from these bodies may ultimately be needed to provide us with solutions. In the book Asteroids IV, the editors and authors have taken major strides in the long journey toward a much deeper understanding of our fascinating planetary ancestors. This book reviews major advances in 43 chapters that have been written and reviewed by a team of more than 200 international authorities in asteroids. It is aimed to be as comprehensive as possible while also remaining accessible to students and researchers who are interested in learning about these small but nonetheless important worlds. We hope this volume will serve as a leading reference on the topic of asteroids for the decade to come. We are deeply indebted to the many authors and referees for their tremendous efforts in helping us create Asteroids IV. We also thank the members of the Asteroids IV scientific organizing committee for helping us shape the structure and content of the book. The conference associated with the book, "Asteroids Comets Meteors 2014" held June 30-July 4, 2014, in Helsinki, Finland, did an outstanding job of demonstrating how much progress we have made in the field over the last decade. We are extremely grateful to our host Karri Muinonnen and his team. The editors are also grateful to the Asteroids IV production staff, namely Renée Dotson and her colleagues at the Lunar and Planetary Institute, for their efforts, their invaluable assistance, and their enthusiasm; they made life as

    Full Text Available The aims of this study were to determine endemic and epidemic infection due to Gram-negative bacilli, risk factors associated with colonization and infection by these organisms and the resistance phenotypes (ESBL, AmpC in neonates admitted in a High Risk Nursery. The study was conducted during a 21 month period and included: a prospective study to evaluate the neonates with hospital infection and the use of third-generation cephalosporins; a case-control study to determine the risk factors associated with colonization/infection. Rectal and oropharynx cultures were also performed in four opportunities (September and November 2001, February and August 2002. The isolates for which the resistance of ceftazidime was 2 mg/mL were suspected of producing ESBL or AmpC b-lactamases. The incidence of infection by Gram-negative bacilli was 2.4% (89/3.708 neonates, and sepsis (35.9% and conjunctivitis (31.4% were the most common infections. The endemic infections were more prevalent (73.9% and usually associated with Enterobacteriaceae (95.5%, being these organisms also related to colonization, corresponding mainly to isolates of Enterobacter spp. and Klebsiella spp. Two outbreaks of Pseudomonas aeruginosa (n=10 and Acinetobacter baumannii (n=11 were identified during the survey. Univariate analysis showed that risk factors for Gram-negative bacilli infection considered significant included: the length of stay before infection/colonization, exposure to antimicrobial agents, mechanical ventilation, central venous catheters, parenteral nutrition and surgery. The majority of resistance to ceftazidime among Enterobacteriaceae isolates (80.9% was from ESBL phenotype. Administration of third-generation cephalosporins (ceftriaxone led to the emergence of these multiresistant Gram-negative bacilli in the neonatal unit.Os objetivos deste estudo foram determinar infecções endêmicas e epidêmicas por bacilos Gram-negativos, fatores de risco associados a coloniza

    Methicillin-resistant Staphylococcus aureus (MRSA) infections have changed since certain non-multiresistant MRSA lineages have emerged in hospitals. In this study, 99 MRSA isolates, 77 from a public and 22 from a private hospital, were characterized. Isolates were tested for antimicrobial susceptibility, whereas staphylococcal chromosomal cassette mec (SCCmec) typing and Panton-Valentine leukocidin genes were assessed by polymerase chain reaction. Pulsed-field gel electrophoresis and multilocus sequence typing analyses were carried out to determine the MRSA lineages. High rates of resistance were found to erythromycin (96%), ciprofloxacin (93%), and clindamycin (90%). The SCCmec types found were as follows: type II (14.2%), III (62.6%), and IV (23.2%). Approximately 85% of type III isolates was related to the Brazilian epidemic clone in both hospitals. For type IV isolates, 94.4% were related to both USA400/ sequence type (ST) 1 and USA800/ST5 lineages in the public hospital, whereas the USA400/ST1, USA800/ST5, USA1100/ST30, and EMRSA (Epidemic MRSA)-15/ST22 lineages were detected in the private hospital. Among the SCCmec II isolates, approximately 85% were related to the USA100/ST5 lineage. Three MRSA isolates were positive to Panton-Valentine leukocidin genes. The study showed that there was an emergence of USA400/ST1, USA800/ST5 SCCmec IV, and USA100/ST5 SCCmec II MRSA lineages in both hospitals. There was a dissemination of them in the public hospital and a polyclonal presence of the MRSA isolates in the private hospital. The spread of these lineages can be facilitated by the characteristics of the health institution. Copyright © 2013 Association for Professionals in Infection Control and Epidemiology, Inc.

    Recovery from obstetrics and gynecology (OB/GYN) surgery, including hysterectomy and cesarean section delivery, aims to restore function while minimizing hospital length of stay (LOS) and medical expenditures. Our analyses compare OB/GYN surgery patients who received combination intravenous (IV) acetaminophen and IV opioid analgesia with those who received IV opioid-only analgesia and estimate differences in LOS, hospitalization costs, and opioid consumption. We performed a retrospective analysis of the Premier Database between January 2009 and June 2015, comparing OB/GYN surgery patients who received postoperative pain management with combination IV acetaminophen and IV opioids with those who received only IV opioids starting on the day of surgery and continuing up to the second postoperative day. We performed instrumental variable 2-stage least-squares regressions controlling for patient and hospital covariates to compare the LOS, hospitalization costs, and daily opioid doses (morphine equivalent dose) of IV acetaminophen recipients with that of opioid-only analgesia patients. We identified 225 142 OB/GYN surgery patients who were eligible for our study of whom 89 568 (40%) had been managed with IV acetaminophen and opioids. Participants averaged 36 years of age and were predominantly non-Hispanic Caucasians (60%). Multivariable regression models estimated statistically significant differences in hospitalization cost and opioid use with IV acetaminophen associated with $484.4 lower total hospitalization costs (95% CI = -$760.4 to -$208.4; P = 0.0006) and 8.2 mg lower daily opioid use (95% CI = -10.0 to -6.4), whereas the difference in LOS was not significant, at -0.09 days (95% CI = -0.19 to 0.01; P = 0.07). Compared with IV opioid-only analgesia, managing post-OB/GYN surgery pain with the addition of IV acetaminophen is associated with decreased hospitalization costs and reduced opioid use.

    The aim of this study was to calculate and analyze the cost of treatment for stage IV pressure ulcers. A retrospective chart analysis of patients with stage IV pressure ulcers was conducted. Hospital records and treatment outcomes of these patients were followed up for a maximum of 29 months and analyzed. Costs directly related to the treatment of pressure ulcers and their associated complications were calculated. Nineteen patients with stage IV pressure ulcers (11 hospital-acquired and 8 community-acquired) were identified and their charts were reviewed. The average hospital treatment cost associated with stage IV pressure ulcers and related complications was $129,248 for hospital-acquired ulcers during 1 admission, and $124,327 for community-acquired ulcers over an average of 4 admissions. The costs incurred from stage IV pressure ulcers are much greater than previously estimated. Halting the progression of early stage pressure ulcers has the potential to eradicate enormous pain and suffering, save thousands of lives, and reduce health care expenditures by millions of dollars.

    Full Text Available O peso ao nascer do recém-nascido é o resultado de diversos fatores (orgânicos, psíquicos e sociais sobre o potencial genético do feto. É natural que sua distribuição seja diferente conforme as características da população. Desta maneira, pretendeu-se estudar o peso ao nascer dos recém-nascidos vivos, de 1978 e 1979, de duas grandes maternidades de Florianópolis, SC (Brasil, nas quais ocorrem 90% dos partos da região, segundo sexo, tipo de nascimento e filiação previdenciária das mães. Observou-se que a média de peso ao nascer dos 18.491 recém-nascidos vivos estudados foi de 3.347,6g. Nessa população ocorreu 5,3% de baixo peso ao nascer e 11,1% de crianças com 4.000g ou mais. As crianças do sexo masculino pesaram ao nascer mais que as do sexo feminino, sendo esta diferença estatisticamente significativa. O mesmo fato ocorreu com as crianças de nascimentos únicos e múltiplos, tendo os primeiros peso ao nascer maior que os segundos, sendo também esta diferença estatisticamente significativa. O estudo da relação entre a filiação previdenciária das mães e o peso ao nascer das crianças mostrou que as mulheres da classe "indigente/serv. social" tiveram número significativamente maior de recém-nascidos de baixo peso do que os de outras categorias sociais. Esses dados mostram que a população estudada apresentou uma baixa incidência de baixo peso ao nascer, com uma distribuição de peso ao nascer semelhante a de países adiantados.Birthweight is the result of many factors (organic, psychological, social acting on the genetic potential of the fetus.

Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. Após a consistência dos dados, foram avaliadas as seguintes variáveis: ganho em peso médio diário, consumo de ração médio diário e conversão alimentar, para os períodos: 1 a 28, 1 a 56, 1 a 70 e 1 a 84 dias de idade; peso corporal ao nascimento, aos 28, 56, 70 e aos 84 dias de idade. O desempenho dos genótipos foi avaliado por meio da análise de variância multivariada e da função discriminante linear de Fisher, usando os testes do maior autovalor de Roy e da união-interseção de Roy para as comparações múltiplas. O estudo da divergência genética foi feito por meio da análise por variáveis canônicas e pelo método de otimização de Tocher. Os genótipos Caboclo e Gigante Negro apresentaram médias canônicas diferentes dos demais genótipos. As duas primeiras variáveis canônicas explicaram 97,41% da variação entre os genótipos. A divergência genética entre os genótipos avaliados permitiu a formação de quatro grupos com os seguintes genótipos: grupo 1 - Colorpak; grupo 2 - Pesadão Vermelho e Pescoço Pelado; grupo 3 - Carijó e Tricolor; e grupo 4 - Caboclo e Gigante Negro.

    The equilibrium solubility of neptunium (IV) oxalate in nitric/oxalic acid solutions was determined at 22 0 C, 45 0 C, and 60 0 C. The concentrations of nitric/oxalic acid solutions represented a wide range of free oxalate ion concentration. A mathematical solubility model was developed which is based on the formation of the known complexes of neptunium (IV) oxalate. the solubility model uses a simplified concentration parameter which is proportional to the free oxalate ion concentration. The solubility model can be used to estimate the equilibrium solubility of neptunium (IV) oxalate over a wide range of oxalic and nitric acid concentrations at each temperature

    Full Text Available FUNDAMENTO: Tem sido sugerido que o polimorfismo da haptoglobina pode influenciar na patogênese das complicações microvasculares e macrovasculares em pacientes diabéticos. OBJETIVO: O objetivo principal deste estudo transversal foi de realizar uma investigação da existência ou não de uma associação entre os genótipos de haptoglobina e a prevalência de eventos isquêmicos cardiovasculares (angina estável, angina instável e infarto agudo do miocárdio, hipertensão arterial sistêmica, hipertensão refratária, obesidade e dislipidemia em 120 pacientes com diabete melito tipo 2, seguidos no Hospital Universitário da Unicamp, em Campinas, Estado de São Paulo. MÉTODOS: A genotipagem da haptoglobina foi realizada por reações em cadeia da polimerase alelo-específicas. As frequências dos genótipos de haptoglobina foram comparadas com a presença/ausência de doença cardiovascular, hipertensão arterial sistêmica, hipertensão refratária, obesidade e dislipidemia; medições de pressão arterial sistólica e diastólica; glicemia, colesterol (total, lipoproteínas de alta densidade - HDL e lipoproteínas de baixa densidade - LDL e triglicerídeos; assim como níveis de creatinina sérica. RESULTADOS: Embora nenhuma associação entre o genótipo de haptoglobina e a presença de doença cardiovascular tenha sido identificada, encontramos um excesso significativo de pacientes com o genótipo Hp2-1 entre as pessoas com hipertensão refratária, que também apresentavam uma maior pressão arterial sistólica e diastólica e níveis de colesterol total e LDL. CONCLUSÃO: Nossos resultados sugerem que os pacientes com diabete melito tipo 2 com o genótipo Hp2-1 podem apresentar uma maior chance de desenvolver hipertensão refratária. Estudos adicionais em populações diabéticas são necessários para confirmar esses achados.

  11. Tipos de tirano y resistencia en Francisco Suárez

    Full Text Available El presente artículo pretende analizar la discusión que Francisco Suárez mantiene con las tesis contrarias a la distinción entre tipos de tirano en la cuestión del tiranicidio (Defensio fidei, Libro VI, capítulo IV, números 10-13. Para esta visión no le es lícito a una persona privada matar a ninguno de los dos tipos de tirano; sólo es posible darles muerte en legítima defensa, porque se entiende que en tal caso se actúa en ejercicio de autoridad pública. Suárez acaba admitiendo esta tesis en el número 13, lo que parece contradecirse con lo sostenido en el número 7, donde se aceptaba la muerte del usurpador por cualquier particular. Sin embargo, en el fondo mantiene la diferencia entre ambos tipos de tirano, por cuanto que en el caso del usurpador sostiene que siempre se dan las condiciones para alegar legítima defensa. Queda sin aclarar qué ocurre en tal caso con las condiciones dispuestas en los números 8 y 9.

  18. Enhanced Design Alternative IV

    International Nuclear Information System (INIS)

    Kramer, N.E.

    1999-01-01

    This report evaluates Enhanced Design Alternative (EDA) IV as part of the second phase of the License Application Design Selection (LADS) effort. The EDA IV concept was compared to the VA reference design using criteria from the Design Input Request for LADS Phase II EDA Evaluations (CRWMS M and O 1999b) and (CRWMS M and O 1999f). Briefly, the EDA IV concept arranges the waste packages close together in an emplacement configuration known as line load. Continuous pre-closure ventilation keeps the waste packages from exceeding their 350 C cladding and 200 C (4.3.6) drift wall temperature limits. This EDA concept keeps relatively high, uniform emplacement drift temperatures (post-closure) to drive water away from the repository and thus dry out the pillars between emplacement drifts. The waste package is shielded to permit human access to emplacement drifts and includes an integral filler inside the package to reduce the amount of water that can contact the waste form. Closure of the repository is desired 50 years after first waste is emplaced. Both backfill and drip shields will be emplaced at closure to improve post-closure performance. The EDA IV concept includes more defense-in-depth layers than the VA reference design because of its backfill, drip shield, waste package shielding, and integral filler features. These features contribute to the low dose-rate to the public achieved during the first 10,000 years of repository life as shown in Figure 3. Investigation of the EDA IV concept has led to the following general conclusions: (1) The total life cycle cost for EDA IV is about $21.7 billion which equates to a $11.3 billion net present value (both figures rounded up). (2) The incidence of design basis events for EDA IV is similar to the VA reference design. (3) The emplacement of the waste packages in drifts will be similar to the VA reference design. However, heavier equipment may be required because the shielded waste package will be heavier. (4) The heavier

  2. A sputnik IV saga

    2009-12-01

    The Sputnik IV launch occurred on May 15, 1960. On May 19, an attempt to deorbit a 'space cabin' failed and the cabin went into a higher orbit. The orbit of the cabin was monitored and Moonwatch volunteer satellite tracking teams were alerted to watch for the vehicle demise. On September 5, 1962, several team members from Milwaukee, Wisconsin made observations starting at 4:49 a.m. of a fireball following the predicted orbit of Sputnik IV. Requests went out to report any objects found under the fireball path. An early morning police patrol in Manitowoc had noticed a metal object on a street and had moved it to the curb. Later the officers recovered the object and had it dropped off at the Milwaukee Journal. The Moonwarch team got the object and reported the situation to Moonwatch Headquarters at the Smithsonian Astrophysical Observatory. A team member flew to Cambridge with the object. It was a solid, 9.49 kg piece of steel with a slag-like layer attached to it. Subsequent analyses showed that it contained radioactive nuclei produced by cosmic ray exposure in space. The scientists at the Observatory quickly recognized that measurements of its induced radioactivity could serve as a calibration for similar measurements of recently fallen nickel-iron meteorites. Concurrently, the Observatory directorate informed government agencies that a fragment from Sputnik IV had been recovered. Coincidently, a debate in the UN Committee on Peaceful Uses of Outer Space involved the issue of liability for damage caused by falling satellite fragments. On September 12, the Observatory delivered the bulk of the fragment to the US Delegation to the UN. Two days later, the fragment was used by US Ambassador Francis Plimpton as an exhibit that the time had come to agree on liability for damage from satellite debris. He offered the Sputnik IV fragment to USSR Ambassador P.D. Morozov, who refused the offer. On October 23, Drs. Alla Massevitch and E.K. Federov of the USSR visited the

En el campo de los materiales cabe una marcada subdivisión en naturales y preparados o sintéticos; estos últimos constituyen la preocupación de los autores para su aprovechamiento y adecuada aplicación. De entre ellos, las resinas sintéticas o caucho artificial, dentro de las distintas especies de la extensa familia han gozado de un lugar preferente en este estudio de nuevos tipos de apoyos que presentan los notables ingenieros alemanes Wolfhart Andrä y Fritz Leonhardt. En los ensayos de laboratorio y a escala natural, las variedades comerciales de estas resinas, conocidas con los nombres de «neopreno» y «Teflon», han sido elegidas por presentar, por lo menos actualmente, características marcadamente apropiadas a la finalidad perseguida en este estudio, del que se confía ulterior desarrollo y mejor acogida, por las importantes aplicaciones que de él se derivan en el campo de la ingeniería y construcción. Los autores estudian con detenimiento y sobrado rigor para las aplicaciones prácticas las deformaciones que de estos materiales se espera al someterlos a fuerzas de gran concentración. En los apoyos juega particular interés la distribución de la carga siempre concentrada en superficies relativamente pequeñas, lo que exige elevadas cargas unitarias y, con ello, la utilización de materiales extremadamente nobles para resistirlas con la resistencia que las deformaciones instantáneas requieren para recobrar rápidamente la posición de estabilidad perdida momentáneamente. La fatiga en el ciclo de deformaciones relaja los materiales, y ha de tenerse presente al considerar las características que los

    Stage IV-S neuroblastoma describes a group of infants with tumor spread limited to liver, skin, or bone marrow. Such patients, who constitute about 25% of affected infants with neuroblastoma, may expect spontaneous tumor remission. We report 18 infants with Stage IV-S neuroblastoma, 83% of whom had liver involvement. Imaging investigations included Technetium 99m sulfur colloid scan, ultrasound, and CT. Two patterns of liver metastasis were noted: ill-defined nodules or diffuse tumor throughout the liver. Distinction of normal and abnormal liver with diffuse type metastasis could be quite difficult, particularly with liver scans. We conclude that patients with Stage IV-S neuroblastoma have ultrasound or CT examination as an initial workup, with nuclear medicine scans reserved for followup studies. (orig.)

    Full Text Available Objetivou-se com este trabalho avaliar as características de desempenho e de carcaça de sete genótipos de frangos tipo caipira da linhagem Redbro. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. Os frangos foram alojados em 28 boxes, sendo 30 frangos por boxe, em galpão de alvenaria com acesso a um piquete de 45m², em quatro repetições. As características de desempenho (conversão alimentar, ganho em peso médio diário, consumo de ração médio diário foram avaliadas nos períodos: um a 28, um a 56, um a 70 e um a 84 dias de idade. O peso corporal foi avaliado aos 28, 56, 70 e 84 dias de idade. As características de carcaça (peso e rendimento de carcaça, peito e pernas foram obtidas a partir do abate de dois frangos por boxe, aos 85 dias de idade. As análises estatísticas foram realizadas utilizando-se o "proc glm" do SAS. Verificou-se que, em todos os períodos, os frangos do genótipo Colorpak apresentaram maior peso corporal, consumo de ração médio diário, ganho em peso médio diário e melhor conversão alimentar. Entretanto, os genótipos Caboclo e Gigante Negro apresentaram menores consumo de ração médio diário, ganho de peso médio diário e pior conversão alimentar. Quanto ao rendimento de cortes, observou-se que os genótipos Caboclo e Gigante Negro apresentaram os menores valores, e o Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor obtiveram os melhores rendimentos de pernas. Para o rendimento de peito, o Carijó e o Pesadão Vermelho obtiveram os maiores valores. A escolha do genótipo deve ser feita de acordo com o interesse do mercado, pois há diferenças no desempenho e no rendimento de carcaça e dos cortes.

En Colombia, las principales causas de estas lesiones las constituyen situaciones de guerra y ataques terroristas puesto que el país se ha visto inmerso en la violencia durante varios años. Material y Métodos: Debido a la severidad y el compromiso de áreas resultantes de ese tipo de eventos, se diseñó e implemento un protocolo de atención que se propuso realizar lo siguiente: 1 Aplicar la evaluación primaria y secundaria del paciente, según los lineamientos del Soporte Vital Avanzado en Trauma del Colegio Americano de Cirujanos. 2 Hacer la evaluación sistemática por áreas anatómicas por parte del departamento quirúrgico, orientándola hacia el examen de las lesiones descritas con mayor frecuencia. 3 Llevar a cabo posteriormente una valoración de las lesiones específicas de acuerdo con las especialidades relacionadas. Para identificar las lesiones más frecuentes, se realizó un análisis retrospectivo de los casos registrados en el Hospital Universitario de Neiva, centro de referencia para el suroccidente de Colombia. Resultados: Durante ese periodo, se atendieron 35 pacientes cuyas áreas anatómicas comprometidas más frecuentes fueron las extremidades inferiores (con un registro del 60% de los casos, el abdomen (54,3% y el tórax (42,9%. La mortalidad general del grupo fue de 9,1%. Después de la implementación, se demostró una mejoría en la oportunidad de evaluación por cirugía general y se identificaron 6 pacientes con diagnósticos tardíos, previos a la implementación del protocolo. Conclusión: Este estudio determinó que la implementación de una revisión secuencial y un protocolo sistemático permiten mejorar la tasa de diagnósticos tardíos optimizando la evaluación diagnostica y el abordaje terapéutico.

    Full Text Available Abstract Introduction The treatment of complex liver injuries remains a challenge. Nonoperative treatment for such injuries is increasingly being adopted as the initial management strategy. We reviewed our experience, at a University teaching hospital, in the nonoperative management of grade IV liver injuries with the intent to evaluate failure rates; need for angioembolization and blood transfusions; and in-hospital mortality and complications. Methods This is a retrospective analysis conducted at a single large trauma centre in Brazil. All consecutive, hemodynamically stable, blunt trauma patients with grade IV hepatic injury, between 1996 and 2011, were analyzed. Demographics and baseline characteristics were recorded. Failure of nonoperative management was defined by the need for surgical intervention. Need for angioembolization and transfusions, in-hospital death, and complications were also assessed Results Eighteen patients with grade IV hepatic injury treated nonoperatively during the study period were included. The nonoperative treatment failed in only one patient (5.5% who had refractory abdominal pain. However, no missed injuries and/or worsening of bleeding were observed during the operation. None of the patients died nor need angioembolization. No complications directly related to the liver were observed. Unrelated complications to the liver occurred in three patients (16.7%; one patient developed a tracheal stenosis (secondary to tracheal intubation; one had pleural effusion; and one developed an abscess in the pleural cavity. The hospital length of stay was on average 11.56 days. Conclusions In our experience, nonoperative management of grade IV liver injury for stable blunt trauma patients is associated with high success rates without significant complications.

    Full Text Available The metal-ceramic composite actuators, moonies and cymbals consist in capped piezoceramic disks with metallic endcaps having cavities inside. These cavities favour the amplification of direct and reverse piezoelectric effects. These actuators fill the gap between high displacement low generative force bimorph actuators and low displacement high generative force multilayer ceramic actuators. The moonie actuator can give displacements greater than 100 mm, maximum generative force of 3N to several N´s, response time of 20 to 100 ms, and low fatigue test response for more than 107 cycles. Cymbals actuators shows twice as big as displacement than moonie for the studied size, much higher generative force and the possibility to avoid the temperature dependence of the displacement for selected materials. Properties of cymbal actuators can be tailored trough the selection of materials. Also, cymbal actuators can be tuned to adopt different resonance frequencies.

    Los composites metal-cerámica tipo luna y címbalo consisten en discos piezoeléctricos encapsulados con cápsulas metálicas que poseen una cavidad. Esta cavidad favorece la amplificación de los efectos piezoeléctricos directo e inverso. Estos actuadores llenan el escalón entre actuadores multicapa, con desplazamientos pequeños y fuerzas generativas elevadas, y actuadores bimorfos, con desplazamientos grandes y fuerzas generativas pequeñas. El actuador tipo luna alcanza desplazamientos de más de 100mm, fuerzas generativas máximas de hasta varios N´s, tiempos de respuesta desde 20 hasta 100ms, y baja respuesta en ensayos de fatiga a más de 107 ciclos.

    Full Text Available INTRODUCTION Laryngoscopy and intubation is an integral part for providing general anaesthesia to patients undergoing various types of surgery. It also plays an important role in critical care units viz. for providing mechanical ventilation. It is a very essential tool in the hands of anaesthesiologist in maintaining airway. The present study is undertaken to determine and compare the efficacy of single bolus dose of IV esmolol 1 mg/kg and IV fentanyl 2 mcg/kg in attenuating the haemodynamic responses to laryngoscopy and tracheal intubation and to ascertain the effectiveness of esmolol hydrochloride and fentanyl citrate in suppressing sympathetic responses. MATERIAL & METHODS The study was conducted under the Department of Anaesthesiology and Critical Care, Assam Medical College and Hospital, Dibrugarh, during the period July 2013 to June 2014. For this purpose, 150 patients of either sex between 20-50 years of ASA I & II physical status were selected after obtaining informed and written consent and were divided into two groups namely, Group E receiving IV esmolol (1 mg/kg and Group F receiving IV fentanyl (2 mcg/kg. RESULTS Inj. fentanyl 2 mcg/kg IV administered 5 minutes before laryngoscopy and intubation was able to prevent adverse haemodynamic changes better than Inj. esmolol 1 mg/kg IV administered 3 minutes prior to laryngoscopy and intubation during elective surgeries under general anaesthesia. CONCLUSION Hence, from the findings of this study we can conclude that IV bolus dose of fentanyl 2 mcg/kg administered 5 minutes before laryngoscopy and intubation can attenuate the sympathetic response to laryngoscopy and intubation without any side effects of the drug in healthy patients undergoing elective surgeries under general anaesthesia.

    Full Text Available Dos de los tipos de pitahaya mas cultivados en la Península de Yucatán, México, difieren principalmente por el color de su cáscara, el primero es de color rojo (Uqroo1, perteneciente a Hylocereus undatus, mientras que en el segundo es color amarillo claro (Uqroo2, hasta el momento también identificado como H. undatus; este último es mas dulce. En ambos tipos de pitahayas, se realizaron autopolinizaciones y polinizaciones cruzadas directas y recíprocas, con el propósito de evaluar el efecto en la cantidad de frutos que lograron su desarrollo. Se midieron algunas variables para detectar la influencia del progenitor paterno en algunas características del fruto. Los testigos se obtuvieron de flores polinizadas libremente. El diseño experimental utilizado fue completamente al azar, con 15 repeticiones por tratamiento. Se encontró que Uqroo1 es autocompatible, mientras que Uqroo2 es autoincompatible. Los testigos de ambos tipos alcanzaron el mismo peso, y los frutos de Uqroo2 logrados por polinización cruzada tuvieron un peso similar al de los testigos o fueron significativamente mas pesados. Algunas variables resultaron positivamente correlacionados; el coeficiente entre el número de semillas y el peso total del fruto fue de r = 0.84. La correlación mas alta (r = 0.97 resultó entre el peso total y el peso de la pulpa. En los frutos obtenidos por polinización cruzada prevalecieron las características del progenitor materno. Se recomienda cultivar la Pitahaya blanca con otro tipo de pitahaya, además de Uqroo1There are two types of pitahaya that are cultivated in Yucatan Peninsula of Mexico. They differ mainly in the skin color of the fruit, one of them has a red skin (Uqroo1, while the other has a light yellow skin (Uqroo2 both belong to Hylocereus undatus (Haworth Britt. & Rose. The yellow skin pitahaya is the sweetest. The studies were conducted using the methods of self pollination and cross pollination, with direct crosses and

    The ion exchange behaviour of seven crystalline cerium(IV) phosphates towards some of the alkali metal cations is described. Only two of the compounds (A and C) possess ion exchange properties in acidic solutions. Four others show some ion exchange characteristics in basic media with some of the alkali cations. Compound G does not behave as an ion exchanger in solutions of pH + , but show very little Na + uptake. Compound E undergoes ion exchange with Na + and Cs + , but not with Li+. Both Li + and Na + are sorbed by compounds A and C. The results are indicative of structures which show steric exclusion phenomena. (author)

    Oxo-manganese-tetraphenylporphyrin (O=Mn{sup IV}-TPP) has been prepared by an oxygen-transfer reaction from iodosylbenzene to MnIITPP and characterized by its i.r. and field desorption mass spectra, which are identical to those of the product obtained by direct oxidation of Mn{sup III}(TPP) in an aqueous medium; it transfers oxygen to triphenylphosphine to produce triphenylphosphine oxide, and it is suggested that similar intermediates are important in oxygen activation by cytochrome P-450 as well as in the photosynthetic evolution of oxygen.

    Full Text Available This hospital is built on the circular system. This arrangement has economic and functional advantages. The nurses walk 40 % less distance than in a hospital of similar size, of conventional layout. The rooms are situated along the external perimeter and the beds are orientated towards the corridor, rather than towards the window. However, the patients can see out of doors by turning on their side. The hospital is most carefully fitted out, and is very comfortable. There is air conditioning, and patients can control their own TV sets. There are also curtains separating each bed form the rest, thus providing maximum independence. Warm colours have been adopted in the decoration of rooms facing north, whilst those facing south are painted in cooler tones. The circular design arrangement makes the distribution far more flexible, and it will be easier to include further units later on; by adding small adjustments to the central building. To reduce external noise, and to improve the surrounding landscape, small sand hills have been provided in the garden, and the parking site also serves to partially absorb the noise.Presenta esta solución de unidades circulares numerosas ventajas de tipo económico, ahorra espacio y da eficiencia a la circulación— las enfermeras recorren un 40 por 100 menos de camino que en otro hospital de dimensiones similares—. Las habitaciones están distribuidas a lo largo del perímetro exterior y tienen las camas orientadas hacia los corredores, en lugar de hacia las ventanas, pero de tal modo que los pacientes puedan contemplar el exterior al volverse sobre uno de sus costados. Están cuidadosamente diseñadas y dotadas de las máximas comodidades: aire acondicionado y aparatos de televisión controlados por el paciente; así como cortinas divisorias que le proporcionan el grado de aislamiento deseado.

    Full Text Available The Castulo cup is one of the most common black glaze Attic forms in the Iberian Peninsula from the Atlantic coast to Ampurias. Their date in the Iberian Peninsula is some years later than that proposed for Athens. They did not appear till some years after the second half of the 5th c. B.C. Their production probably continued until the first quarter of the 4th century B.C. They are almost fixed in their form for about a century, but some differences in the outside decoration and the underside of the foot can be pointed out. Two main types are proposed for the second half of the 5th century and the first quarter of the 4th century B.C. The differences in date compared with those found at Athens can be explained as an adaptation of the workshops to the demands of Iberian customers. Athen's artisans continued making Castulo cups for export at a time when in Athens they did not use them any more, because the stemless cup had been replaced by the popular kantharoi and cup-kantharoi.

    La copa Cástulo es una de las formas áticas de barniz negro más abundante en los yacimientos peninsulares desde la costa atlántica hasta Ampurias. Su cronología es en la Península Ibérica algo posterior a la propuesta para Atenas. No aparecen hasta algo después de mediados del siglo V y probablemente se continúan fabricando hasta el primer cuarto del IV a. C. No experimentan durante casi un siglo de producción ninguna variación formal, sin embargo sí se pueden ver diferencias en el tratamiento de la decoración exterior y del fondo externo. Se proponen aquí fundamentalmente dos tipos de la segunda mitad del siglo V y primer cuarto del IV a. C. La diferencia cronológica con las halladas en Atenas se explica como una adaptación de los talleres áticos a la demanda de los clientes ibéricos. Los artesanos atenienses continúan fabricando copas Cástulo para la exportación cuando en Atenas se han dejado ya de utilizar las copas de pie bajo al ser

    Straightforward access to a cerium(IV)-carbene complex was provided by one-electron oxidation of an anionic ''ate'' cerium(III)-carbene precursor, thereby avoiding decomposition reactions that plague oxidations of neutral cerium(III) compounds. The cerium(IV)-carbene complex is the first lanthanide(IV)-element multiple bond and involves a twofold bonding interaction of two electron pairs between cerium and carbon. [German] Auf direktem Wege zu einem Cer(IV)-Carbenkomplex gelangt man durch die Einelektronenoxidation einer anionischen Carben-Cerat(III)-Vorstufe. So werden Zersetzungsprozesse vermieden, die die Oxidation neutraler Cer(III)-Verbindungen erschweren. Der Cer(IV)-Carbenkomplex enthaelt die erste Lanthanoid(IV)-Element-Mehrfachbindung; dabei binden Cer und Kohlenstoff ueber zwei Elektronenpaare.

    A comparative study of costs per bed per day in teaching hospitals affiliated with Monash University compared with large non-teaching metropolitan hospitals (1964 to 1974) shows they are much higher in teaching hospitals. There is no evidence that this is due to the additional costs arising from the clinical schools. Research in the teaching hospitals and the accompanying high professional standards and demands on services are major factors accounting for the difference. Over the decade studied, the resident staff have increased by 77% and other salaried staff by 24%. The index of expenditure for the three teaching hospitals in the decade has increased by 386%.

    1980-01-01

    Wavelength data and classifications of 974 Cu IV lines in the region 750-1275 Angstroem are presented. Most of the lines have been classified as transitions from the previously unknown high even configurations 3d 7 5s and 3d 7 4d to 3d 7 4p. The configuration 3d 7 4d is seriously perturbed by 3d 6 4s 2 . The analysis resulted in the identification of 27 levels of 3d 7 5s and 113 levels of (3d 7 4d + 3d 6 4s 2 ) which are reported. The earlier published levels of 3d 7 4s and 3d 7 4p have to be shifted downward as a consequence of improved wavelength data. Radial paramter values, resulting from least-squares fits, are compared to Hartree-Fock values. The eigenvectors obtained in the parametric fitting are used to calculate transition probabilities in intermediate coupling. The relation between the observed intensities of the transitions 3d 7 4d-3d 7 4p and 3d 7 Ss-3d 7 4p is compared to the relation between theoretical values of the transition integrals obtained from Hartree-Fock calculations. A spectroscopic value for the ionization potentials is calculated from the 3d 7 ns configurations. (orig.)

    It was investigated a series of pigments of general composition Ce 1-x Pr x O 2 , and Ce x Tb y O 2 , exhibiting radish and brown colors, respectively, and high temperature stability. The pigments were obtained by dissolving appropriate amounts of the pure lanthanide oxides in acids and precipitating the rare earths as mixed oxalates, which were isolated and calcined under air, at 1000 0 C. X-Ray powder diffractograms were consistent with a cubic structure for the pigments. Magnetic susceptibility measurements, using Gouy method, indicated the presence of Pr(IV) ions in the Ce 1-x Pr x O 2 pigments and of Terbium predominantly as Tb(III) ions in the Ce-tb mixed oxides. A new method, based on suspension of solid samples in PVA-STB gels (STB = sodium tetradecaborate), was employed for the measurements of the electronic spectra of the pigments. The thermal behaviour the pigments was investigated by the calcination of the oxalates in the temperature range of 500 to 1200 O C, from 10 to 60 minutes. (author)

    Generation IV international forum (GIF) was initiated in 2000 by DOE (American department of energy) in order to promote nuclear energy in a long term view (2030). GIF has selected 6 concepts of reactors: 1) VHTR (very high temperature reactor system, 2) GHR (gas-cooled fast reactor system), 3) SFR (sodium-cooled fast reactor system, 4) SCWR (super-critical water-cooled reactor system), 5) LFR (lead-cooled fast reactor system), and 6) MFR (molten-salt reactor system). All these 6 reactor systems have been selected on criteria based on: - a better contribution to sustainable development (through their aptitude to produce hydrogen or other clean fuels, or to have a high energy conversion ratio...) - economic profitability, - safety and reliability, and - proliferation resistance. The 6 concepts of reactors are examined in the first article, the second article presents an overview of the results of the international project on innovative nuclear reactors and fuel cycles (INPRO) within IAEA. The project finished its first phase, called phase-IA. It has produced an outlook into the future role of nuclear energy and defined the need for innovation. The third article is dedicated to 2 international cooperations: MICANET and HTR-TN. The purpose of MICANET is to propose to the European Commission a research and development strategy in order to develop the assets of nuclear energy for the future. Future reactors are expected to be more multiple-purposes, more adaptable, safer than today, all these developments require funded and coordinated research programs. The aim of HTR-TN cooperation is to promote high temperature reactor systems, to develop them in a long term perspective and to define their limits in terms of burn-up and operating temperature.

    This report provides thermodynamic data for predicting concentrations of Th(IV), U(IV), Np(IV), and Pu(IV) in geologic environments, and contributes to an integration of the JNC chemical thermodynamic database, JNC-TDB (previously PNC-TDB), for the performance analysis of geological isolation system for high-level radioactive wastes. Thermodynamic data for the formation of complexes or compounds with hydroxide, chloride, fluoride, carbonate, nitrate, sulfate and phosphate are discussed in this report. Where data for specific actinide(IV) species was lacking, the data were selected based on chemical analogy to other tetravalent actinides. In this study, the Pitzer ion-interaction model is used to extrapolate thermodynamic constants to zero ionic strength at 25degC. (author)

    Materials science and materials development are key issues for the implementation of innovative reactor systems such as those defined in the framework of the Generation IV. Six systems have been selected for Generation IV consideration: gas-cooled fast reactor, lead-cooled fast reactor, molten salt-cooled reactor, sodium-cooled fast reactor, supercritical water-cooled reactor, and very high temperature reactor. The structural materials need to resist much higher temperatures, higher neutron doses and extremely corrosive environment, which are beyond the experience of the current nuclear power plants. For this reason, the first consideration in the development of Generation-IV concepts is selection and deployment of materials that operate successfully in the aggressive operating environments expected in the Gen-IV concepts. This paper summarizes the Gen-IV operating environments and describes the various candidate materials under consideration for use in different structural applications. (author)

    Acute heart failure (AHF) is a growing public health concern with high inhospital mortality and costs. Clinical practice guidelines, underpinned by positive randomized controlled trials, recommend the early use of intravenous (IV) nitrates in the treatment of AHF. However, the "real-world" usage of IV nitrates has not been clearly defined. The objective of this study was to examine the use of IV nitrates in the treatment of AHF as recommended by clinical practice guidelines. A case-record analysis was conducted of all admissions with AHF at a large teaching hospital. Of the 81 AHF patients (mean age 77 ± 11, mean SBP 130 ± 27 mmHg) enrolled for this analysis, only 5 (6%) received IV nitrates at the time of AHF admission. Forty (49%, mean age 77 ± 11, mean SBP 131 ± 27 mmHg) of these 81 patients met the guideline criteria for suitability for IV nitrates and only 5 (12%) of these received them during this admission. Patients who received IV nitrates were more likely to have higher blood pressure and all had myocardial ischemia as a precipitant. Seventy-five (93%) of the total population received loop diuretics on admission. Overall, this study shows that loop diuretics remain the first-line therapy in AHF with little use of IV nitrates, despite recommendations from clinical practice guidelines. © 2015 John Wiley & Sons Ltd.

    The literature contains no information on adduct formation in Ce(IV) β-diketonates with additional ligands. Since tetrakis-β-diketonates of Ce(IV) have four six-membered chelate rings, we can suppose that the introduction of an additional monodentate or bidentate ligand into the coordination sphere of Ce(IV) β-diketonates would lead to an increase in the coordination number (CN) of the Ce(IV) to nine or ten. The possibility of realization of such a high CN for Ce(IV) has not been proved; a study of adduct formation by Ce(IV) tetrakis-β-diketonates is thus of theoretical interest. Such an investigation might also be of practical interest, because the introduction of an additional ligand into the coordination sphere of a rare-earth β-diketonate usually increases the solubility of the β-diketonate in nonpolar solvents and increases the volatility of the compound; such a modification of the properties is important for various practical purposes. The aim of our work was to study the possibility of separating solid adducts of Ce(IV) tetrakis-thenoyltrifluoroacetonate with certain oxygen-containing and nitrogen-containing donor monodentate and bidentate ligands, and also to investigate their properties. As the β-diketone we used thenoyltrifluoroacetone (HTTFA), since in a parallel investigation it was found that Ce(TTFA) 4 has a high oxidation-reduction stability

    The current supply and demand balance, the short and long term expectations and marketing opportunities for Canadian crude oil in PADD IV, the Rocky Mountain region in the US, were reviewed. It was suggested that market opportunities in PADD IV are derived from the following four factors: (1) crude oil declines within that area, (2) federal regulations, (3) competitive presence with markets, and (4) population growth. The overall conclusion was that Canadian producers and PADD IV refiners will be looking at an ever-growing relationship based on freight equalized world crude prices. 8 tabs., 5 figs

    2012-01-01

    The Generation IV International Forum (GIF) Risk and Safety Working Group (RSWG) was created to develop an effective approach for the safety of Generation IV advanced nuclear energy systems. Recent RSWG work has focused on the definition of an integrated safety assessment methodology (ISAM) for evaluating the safety of Generation IV systems. ISAM is an integrated 'tool-kit' consisting of 5 analytical techniques that are available and matched to appropriate stages of Generation IV system concept development: 1) qualitative safety features review - QSR, 2) phenomena identification and ranking table - PIRT, 3) objective provision tree - OPT, 4) deterministic and phenomenological analyses - DPA, and 5) probabilistic safety analysis - PSA. The integrated methodology is intended to yield safety-related insights that help actively drive the evolving design throughout the technology development cycle, potentially resulting in enhanced safety, reduced costs, and shortened development time

    According to the quantitative reaction of U(IV) and Fe(III) in H 2 SO 4 as well as the relation between current and concentration of substance detected, U(IV) has been determined indirectly by measurement of the electrolysis current of residual Fe(III). The columniform electrode used is made of glass carbon particles. At the range of U(IV) from a few micrograms to 40 μg, the linear relation is excellent. The relative standard deviation is within ±4%. The interference of Fe(II), Ti(IV) and U(VI) is negligible but of Ti(III) is serious. This method has been successfully applied in the determination of actual samples (both out line and on line). Main advantages of this procedure are rapid, simple, small amount of sample (only at microgram level) and easy to realize automation, able to use for on line or process analysis

    Today development of nuclear technology has reached the stage of research and development of Generation IV nuclear power plants (advanced reactor systems) which is an innovative development from the previous generation of nuclear power plants. There are six types of power generation IV reactors, namely: Very High Temperature Reactor (VHTR), Sodium-cooled Fast Reactor (SFR), Gas-cooled Fast Reactor (GFR), Lead-cooled Fast Reactor (LFR), Molten Salt Reactor (MSR), and Super Critical Water-cooled Reactor (SCWR). The purpose of this study is to know the development of Generation IV nuclear power plants that have been done by the thirteen countries that are members of the Gen IV International Forum (GIF). The method used is review study and refers to various studies related to the current status of research and development of generation IV nuclear power. The result of this study showed that the systems and technology on Generation IV nuclear power plants offer significant advances in sustainability, safety and reliability, economics, and proliferation resistance and physical protection. In addition, based on the research and development experience is estimated that: SFR can be used optimally in 2015, VHTR in 2020, while NPP types GFR, LFR, MSR, and SCWR in 2025. Utilization of NPP generation IV said to be optimal if fulfill the goal of NPP generation IV, such as: capable to generate energy sustainability and promote long-term availability of nuclear fuel, minimize nuclear waste and reduce the long term stewardship burden, has an advantage in the field of safety and reliability compared to the previous generation of NPP and VHTR technology have a good prospects in Indonesia.

    Full Text Available Intravenous (IV iron and Erythropoiesis Stimulating Agents (ESAs are recommended for anemia management in chronic kidney disease (CKD. This retrospective cohort study analyzed utilization patterns of IV iron and ESA in patients over 18 years of age admitted to University Health System Hospitals with a primary or secondary diagnosis of CKD between January 1, 2006 to December 31, 2008. A clustered binomial logistic regression using the GEE methodology was used to identify predictors of IV iron utilization. Only 8% (n = 6678 of CKD patients on ESA therapy received IV iron supplementation in university hospitals. Those receiving iron used significantly less amounts of ESAs. Patient demographics (age, race, primary payer, patient clinical conditions (admission status, severity of illness, dialysis status, and physician specialty were identified as predictors of IV iron use in CKD patients. Use of IV iron with ESAs was low despite recommendations from consensus guidelines. The low treatment rate of IV iron represents a gap in treatment practices and signals an opportunity for healthcare improvement in CKD anemic patients.

    The aim of our study is to reflect hearing impairment of 23children diagnosed with mucopolysaccharidosis (MPS) typeI, II, III and IV. Retrospective study of the clinical, audiological and treatment (medical vs surgical) findings of 23children diagnosed with MPS typeI, II, III or IV followed at a Tertiary Referral Hospital between 1997 and 2015. Six cases of MPSI, 8 of MPSII, 4 of MPSIII and 5 of MPSIV were reviewed. 71.2% of patients had secretory otitis media (SOM) and 54% of patients had some type of hearing loss (HL). The behaviour of hearing loss was variable in each of the subgroups of MPS, finding greater involvement and variability in typesI and II. Children with MPS have a high risk of hearing loss. A significant percentage of transmissive HL progressing to mixed or sensorineural HL was observed. This was more common in typesI and II. Periodic follow up of these patients is mandatory because of hearing impairment and consequences for their development and quality of life.

Under oxidizing conditions technetium exists as the anionic species TcO 4 - whereas under the reducing conditions, expected to exist in a deep geological repository, it is generally predicted that technetium will be present as TcO 2 ·nH 2 O. Hence, the mobility of Tc(IV) in reducing groundwater may be limited by the solubility of TcO 2 ·nH 2 O under these conditions. Due to this fact it is important to investigate the solubility of TcO 2 ·nH 2 O. The solubility determines the release of radionuclides from waste form and is used as a source term in radionuclide migration analysis in performance assessment of radioactive waste repository. Technetium oxide was prepared by reduction of a technetate solution with Sn 2 + . The solubility of Tc(IV) oxide has been determined in simulated groundwater and redistilled water under aerobic and anaerobic conditions. The effects of pH and CO 3 2- concentration of solution on solubility of Tc(IV) oxide were studied.

    Full text of publication follows: The deep geological disposal of the high level radioactive wastes is expected to be a safer disposal method in most countries. The long-lived fission product 99 Tc is present in large quantities in nuclear wastes and its chemical behavior in aqueous solution is of considerable interest. Under the reducing conditions, expected to exist in a deep geological repository, it is generally predicted that technetium will be present as TcO 2 .nH 2 O. The solubility of Tc(IV) is used as a source term in performance assessment of radioactive waste repository. Technetium oxide was prepared by reduction of a technetate solution with Sn 2+ . The solubility of Tc(IV) oxide has been determined in simulated groundwater and re-distilled water under aerobic and anaerobic conditions. The effects of pH and CO 3 2- concentration of solution on solubility of Tc(IV) oxide were studied. The concentration of total technetium and Tc(IV) species in the solutions were periodically determined by separating the oxidized and reduced technetium species using a solvent extraction procedure and counting the beta activity of the 99 Tc with a liquid scintillation counter. The experimental results show that the rate of oxidation of Tc(IV) in simulated groundwater and re-distilled water is about (1.49∼1.86) x 10 -9 mol/(L.d) under aerobic conditions, but Tc(IV) in simulated groundwater and re-distilled water is not oxidized under anaerobic conditions. Under aerobic or anaerobic conditions the solubility of Tc(IV) oxide in simulated groundwater and re-distilled water is equal on the whole after centrifugation or ultrafiltration. The solubility of Tc(IV) oxide decreases with the increase of pH at pH 10 and is pH independent in the range 2 -8 to 10 -9 mol/L at 2 3 2- concentration. These data could be used to estimate the Tc(IV) solubility for cases where solubility limits transport of technetium in reducing environments of high-level waste repositories. (authors)

    The purpose of the present work was to develop a method of determining Th(IV), U(IV), Np(N) and Pu(IV) in acid solutions by titration with diethylenetriamine pentacetic acid, the indicator being xylenol orange. It has been established that Th, U, Np and Pu can be determined to within 0.5-1.5%. Th and U in quantities of tens of milligrams can be determined with greater accuracy, attaining hundredths of one per cent. During titration the determination is not hindered by singly- and doubly-charged metal ions, trivalent lanthanides and actinides, except plutonium. The proposed method can be used to determine U(IV) in the presence of considerable quantities of U(VI) and Np(IV) in the presence of Np(V). Total concentrations of uranium or neptunium are determined by reducing uranium (VI) or neptunium (V) by a standard method (for example, using metallic lead, cadmium or zinc amalgam) to the tetravalent state and applying the method described in the paper.

    Since its inauguration in 1999, the International VLBI Service for Geodesy and Astrometry has made significant progress in the coordination and utilisation of worldwide VLBI resources. Improving the visibility of the IVS components to a wider public in turn led to a higher motivation of the individuals to contribute to the global effort. Not only the number of IVS components but also their investments in terms of funds and manpower demonstrate the increased awareness of the importance of this joint international endeavour. The different demands of the users but also of the contributors often require the definition of priorities which are only being acceptable due to the existence of a strong umbrella organisation like the IVS. Significant progress has also been made in the area of routine data analysis and combination of results. By now, six IVS Analysis Centers provide the redundancy necessary for a robust combination of the results. The use of ITRF2000 station coordinates as the basis for the IVS combined EOP series is the most recent step towards the generation of a consistent chain from the quasi-inertial frame of radio sources to system Earth.

    2001-01-01

    The solubility of Np(IV) in simulated underground water and redistilled water has been measured with the variations of pH(6-12) and storage time (0-100 d) in the presence of reductant (Na 2 S 2 O 4 , metallic Fe). All experiments are performed in a low oxygen concentration glove box containing high purity Ar(99.99%), with an oxygen content of less than 5 x 10 -6 mol/mol. Experimental results show that the variation of pH in solution has little effect on the solubility of Np(IV) in the two kinds of water; the measured solubility of Np(IV) is affected by the composition of solution; with Na 2 S 2 O 4 as a reductant, the solubility of Np(IV) in simulated underground water is (9.23 +- 0.48) x 10 -10 mol/L, and that in redistilled water is (8.31 +- 0.35) x 10 -10 mol/L; with metallic Fe as a reductant, the solubility of Np(IV) in simulated underground water is (1.85 +- 0.56) x 10 -9 mol/L, and that in redistilled water is (1.48 +- 0.66) x 10 -9 mol/L

    In the framework of the Nuclear and Environmental Toxicology program, developed in France, it has been decided to take again the studies concerning the actinides decorporation. A similar study of the neptunium complexation by the citrate ions has been carried out on the complexation of Np(IV) with the nitrilotriacetic acid (NTA). The NTA can be considered as a model molecule of the de-corporating molecules (amino-carboxy- ligand). The results of the spectrophotometric measurements being encouraging, the behaviour of several actinides at the same oxidation state (+IV) (Th(IV), U(IV), Np(IV), and Pu(IV)) has been determined. The experimental results are presented. In order to determine the structure of the complexes of stoichiometry 1:2 An(IV)-(NTA){sub 2} in solution, quantic chemistry calculations and EXAFS measurements have been carried out in parallel. These studies confirm the presence of An(IV)-nitrogen bonds whose length decreases from thorium to plutonium and indicate the presence of a water molecule bound to the thorium and the uranium (coordination number 8 for Np/Pu, 9 for Th/U). The evolution of the complexation constants determined in this study in terms of 1/r (r ionic radius of the cation taking into account its coordination number 8 or 9) confirms the change of the coordination number between Th/U and Np/Pu.

    Nosocomial infections are usually acquired during hospitalization. Fungal infection of the urinary tract is increasing due to predisposing factors such as; antibacterial agents, indwelling urinary catheters, diabetes mellitus, long hospitalization, immunosuppressive agents, use of IV catheters, radiation therapy, malignancy. The aim of our study was to determine the prevalence of candiduria and urinary tract infection in patients admitted in Golestan and Emam Khomeini hospitals of Ahvaz, Iran. During 14 months, a total of 744 urine samples were collected and transferred to medical mycology laboratory immediately. Ten µl of uncentrifuged sample was cultured on CHROM agar Candida plates and incubated at 37°C for 24-48h aerobically. Candida species were identified based on colony morphology on CHROM agar Candida, germ tube production and micro-morphology on corn meal agar including 1% Tween 80. In the present study, 744 hospitalized patients were sampled (49.5%, female; 50.5%, male). The prevalence of candiduria in subjects was 16.5% that included 65.1% female and 34.9% male. The most common isolates were C. albicans (53.3%), followed by C. glabrata (24.4%), C. tropicalis (3.7%), C. krusei (2.2%), and Geotrichum spp. (0.7%) Urine cultures yielded more than 10,000 yeast colonies in 34.1% of cases, and the major predisposing factor associated with candiduria was antibiotic therapy (69.1%). Candiduria is relatively common in hospitalized patients in educational hospitals of Ahvaz. In addition, there is a strong correlation between the incidence of candiduria in hospitalized patients and broad-spectrum antibiotics therapy.

    The multigroup criticality safety code KENO-IV has been vectorized and tested on the FACOM VP-100 vector processor. At first, the vectorized KENO-IV on a scalar processor was slower than the original one by a factor of 1.4 because of the overhead introduced by vectorization. Making modifications of algorithms and techniques for vectorization, the vectorized version has become faster than the original one by a factor of 1.4 on the vector processor. For further speedup of the code, some improvements on compiler and hardware, especially on addition of Monte Carlo pipelines to the vector processor, are discussed

O genótipo TSH1188 apresentou maior comprimento, relação comprimento/largura, espessura e massa de 100 sementes. A absorção de água das sementes recém-colhidas dos genótipos é lenta, justificada pelos altos teores de água, o que não caracteriza padrão-trifásico. Os teores de água reduziram em média 2,3 vezes nas sementes armazenadas em relação às recém-colhidas. A germinação das sementes recém-colhidas dos genótipos foi de 100%. Após o armazenamento, as sementes do PS1319 apresentaram a menor redução da germinação (39%, enquanto as dos PH16, CEPEC2002 e SJ02 reduziram 96%. A velocidade de germinação foi maior e o tempo médio menor que dois dias nas sementes recém-colhidas do PS1319, indicando serem mais tolerante à dessecação.

    Plutonium(IV) carbonate complexes are expected to be of particular importance in typical groundwaters at the Yucca Mountain site of the candidate nuclear waste repository being studied by the Nevada Nuclear Waste Storage Investigations Project. The chemistry of these complexes is also important in the areas of nuclear fuel reprocessing and purification, actinide separations, and environmental studies. This report describes initial experiments performed to determine the identity and equilibrium quotients of plutonium(IV) carbonate complexes. These experiments were performed at pH values between 7.2 and 9.6 using a spectrophotometric method. In addition, a brief review of the published literature on Pu(IV) carbonate complexes is presented. Since Pu(IV) exhibits low solubility in the near-neutral pH range, a complex-competition reaction where citrate ligands compete with carbonate ions for the plutonium will be employed. This will permit us to study the pure carbonate system; study the mixed carbonate/citrate system, and confirm and extend the literature work on the pure citrate system. The current experiments have demonstrated the existence of at least three distinct species in the pH region studied. This work will continue in the extended study of the pure citrate system, followed by the investigation of the citrate/carbonate complex/competition reaction. 9 refs., 4 figs., 2 tabs

    2014-01-01

    A simple way to find solutions of the Painlevé IV equation is by identifying Hamiltonian systems with third-order differential ladder operators. Some of these systems can be obtained by applying supersymmetric quantum mechanics (SUSY QM) to the harmonic oscillator. In this work, we will construct families of coherent states for such subset of SUSY partner Hamiltonians which are connected with the Painlevé IV equation. First, these coherent states are built up as eigenstates of the annihilation operator, then as displaced versions of the extremal states, both involving the related third-order ladder operators, and finally as extremal states which are also displaced but now using the so called linearized ladder operators. To each SUSY partner Hamiltonian corresponds two families of coherent states: one inside the infinite subspace associated with the isospectral part of the spectrum and another one in the finite subspace generated by the states created through the SUSY technique. - Highlights: • We use SUSY QM to obtain Hamiltonians with third-order differential ladder operators. • We show that these systems are related with the Painlevé IV equation. • We apply different definitions of coherent states to these Hamiltonians using the third-order ladder operators and some linearized ones. • We construct families of coherent states for such systems, which we called Painlevé IV coherent states

    The International VLBI Service for Geodesy and Astrometry (IVS) is a globally operating service that coordinates and performs Very Long Baseline Interferometry (VLBI) activities through its constituent components. The VLBI activities are associated with the creation, provision, dissemination, and archiving of relevant VLBI data and products. The products mostly pertain to the determination of the celestial and terrestrial reference frames, the Earth orientation parameters (EOP), atmospheric parameters as well as other ancillary parameters. The IVS observational network currently consists of about 40 radio telescopes worldwide. Subsets of these telescopes (8-12 stations) participate in 24-hour observing sessions that are run several times per week and in 1-hour intensive sessions for UT1 determination every day. The current VLBI network was developed mainly in the 1970s and 1980s. A number of factors, including aging infrastructure and demanding new scientific requirements, started to challenge its future sustainability and relevance. In response, the IVS and other groups developed and started implementing the next generation VLBI system, called VGOS (VLBI Global Observing System), at existing and new sites. The VGOS network is expected to reach maturity in the early 2020s. We describe the current status, progress, and anticipated prospects of geodetic/astrometric VLBI and the IVS.

    2005-01-01

    A Gen IV Materials Handbook is being developed to provide an authoritative single source of highly qualified structural materials information and materials properties data for use in design and analyses of all Generation IV Reactor Systems. The Handbook will be responsive to the needs expressed by all of the principal government, national laboratory, and private company stakeholders of Gen IV Reactor Systems. The Gen IV Materials Handbook Implementation Plan provided here addresses the purpose, rationale, attributes, and benefits of the Handbook and will detail its content, format, quality assurance, applicability, and access. Structural materials, both metallic and ceramic, for all Gen IV reactor types currently supported by the Department of Energy (DOE) will be included in the Gen IV Materials Handbook. However, initial emphasis will be on materials for the Very High Temperature Reactor (VHTR). Descriptive information (e.g., chemical composition and applicable technical specifications and codes) will be provided for each material along with an extensive presentation of mechanical and physical property data including consideration of temperature, irradiation, environment, etc. effects on properties. Access to the Gen IV Materials Handbook will be internet-based with appropriate levels of control. Information and data in the Handbook will be configured to allow search by material classes, specific materials, specific information or property class, specific property, data parameters, and individual data points identified with materials parameters, test conditions, and data source. Details on all of these as well as proposed applicability and consideration of data quality classes are provided in the Implementation Plan. Website development for the Handbook is divided into six phases including (1) detailed product analysis and specification, (2) simulation and design, (3) implementation and testing, (4) product release, (5) project/product evaluation, and (6) product

    1989-01-01

    The systematic liquid-liquid extraction behaviour of oxozirconium (IV), thorium(IV) and dioxouranium(VI) have been investigated using a number of synthesised and commercial chelating extractants. The synergism or antagonism for these processes in presence of neutral donor ligands have also been identified and the conditions for separation and isolation of pure individual metal ions have been established. The coordination behaviour of oxozirconium(IV), thorium(IV) and dioxouranium(VI) with a large number of mono- and polydentate ligands have been studied. With oxozirconium(IV), invariably always a cyclic, tetranuclear species is obtained, derived from the tetrameric structure of the parent ZrOCl 2 .8H 2 O which is actually (Zr 4 (OH) 8 (H 2 O) 16 )Cl 8 .12H 2 O. No simple, monomeric oxozirconium(IV) complex was obtained. Uranium(VI) and thorium(IV) form a wide variety of complexes of higher coordination numbers and several bi- and trinuclear complexes were also characterised where the two adjacent metal centres are joined to each other by a double hydroxo-bridge.

    Intensive care unit (ICU) prognostic models are predominantly used in more developed nations such as the United States, Europe and Australia. These are not that popular in Southeast Asian countries due to costs and technology considerations. The purpose of this study is to evaluate the suitability of the acute physiology and chronic health evaluation (APACHE) IV model in a single centre Malaysian ICU. A prospective study was conducted at the single centre ICU in Hospital Sultanah Aminah (HSA) Malaysia. External validation of APACHE IV involved a cohort of 916 patients who were admitted in 2009. Model performance was assessed through its calibration and discrimination abilities. A first-level customisation using logistic regression approach was also applied to improve model calibration. APACHE IV exhibited good discrimination, with an area under receiver operating characteristic (ROC) curve of 0.78. However, the model's overall fit was observed to be poor, as indicated by the Hosmer-Lemeshow goodness-of-fit test (Ĉ = 113, P discrimination was not affected. APACHE IV is not suitable for application in HSA ICU, without further customisation. The model's lack of fit in the Malaysian study is attributed to differences in the baseline characteristics between HSA ICU and APACHE IV datasets. Other possible factors could be due to differences in clinical practice, quality and services of health care systems between Malaysia and the United States.

    Full Text Available Abstract Ehlers-Danlos syndrome type IV, the vascular type of Ehlers-Danlos syndromes (EDS, is an inherited connective tissue disorder defined by characteristic facial features (acrogeria in most patients, translucent skin with highly visible subcutaneous vessels on the trunk and lower back, easy bruising, and severe arterial, digestive and uterine complications, which are rarely, if at all, observed in the other forms of EDS. The estimated prevalence for all EDS varies between 1/10,000 and 1/25,000, EDS type IV representing approximately 5 to 10% of cases. The vascular complications may affect all anatomical areas, with a tendency toward arteries of large and medium diameter. Dissections of the vertebral arteries and the carotids in their extra- and intra-cranial segments (carotid-cavernous fistulae are typical. There is a high risk of recurrent colonic perforations. Pregnancy increases the likelihood of a uterine or vascular rupture. EDS type IV is inherited as an autosomal dominant trait that is caused by mutations in the COL3A1 gene coding for type III procollagen. Diagnosis is based on clinical signs, non-invasive imaging, and the identification of a mutation of the COL3A1 gene. In childhood, coagulation disorders and Silverman's syndrome are the main differential diagnoses; in adulthood, the differential diagnosis includes other Ehlers-Danlos syndromes, Marfan syndrome and Loeys-Dietz syndrome. Prenatal diagnosis can be considered in families where the mutation is known. Choriocentesis or amniocentesis, however, may entail risk for the pregnant woman. In the absence of specific treatment for EDS type IV, medical intervention should be focused on symptomatic treatment and prophylactic measures. Arterial, digestive or uterine complications require immediate hospitalisation, observation in an intensive care unit. Invasive imaging techniques are contraindicated.

    This project evaluated the predictive validity of the Dynamic Appraisal of Situational Aggression - Inpatient Version (DASA-IV) in a high-secure psychiatric hospital in the UK over 24 hours and over a single nursing shift. DASA-IV scores from three sequential nursing shifts over a 24-hour period were compared with the mean (average of three scores across the 24-hour period) and peak (highest of the three scores across the 24-hour period) scores across these shifts. In addition, scores from a single nursing shift were used to predict aggressive incidents over each of the following three shifts. The DASA-IV was completed by nursing staff during handover meetings, rating 43 male psychiatric inpatients over a period of 6 months. Data were compared to incident reports recorded over the same period. Receiver operating characteristic (ROC) curves and generalized estimating equations assessed the predictive ability of various DASA-IV scores over 24-hour and single-shift timescales. Scores from the DASA-IV based on a single shift had moderate predictive ability for aggressive incidents occurring the next calendar day, whereas scores based on all three shifts had excellent predictive ability. DASA-IV scores from a single shift showed moderate predictive ability for each of the following three shifts. The DASA-IV has excellent predictive ability for aggressive incidents within a secure setting when data are summarized over a 24-hour period, as opposed to when a single rating is taken. In addition, it has moderate value for predicting incidents over even shorter timescales. © 2018 Australian College of Mental Health Nurses Inc.

    Full Text Available Este texto se preocupa em contribuir para a reflexão que torna possível a identificação e ruptura dos estereótipos sociais que dão origem a preconceitos e ações discriminatórias. Com base nos estudos de Walter Lippann, Agnes Heller, Adam Shaff e Eclea Bosi, pretende-se discutir os conceitos de estereótipo e preconceito, buscando entender o que são e porque se formam. Para entender melhor o estereótipo temos que refletir sobre três elementos que a ele se ligam: a linguagem, o cotidiano e o senso comum. É no plano da linguagem - do diálogo e das práticas de linguagem - que se deve estudar e se pode romper e desconstruir os estereótipos, tomando consciência da própria formação discursiva. O texto oferece, ainda, algumas sugestões para trabalhar o conceito na sala de aula e para ampliar o repertório de textos e referências a serem debatidas com os alunos.

    Nine novel dipeptidyl peptidase IV (DPP-IV) inhibitory peptides (FLQY, FQLGASPY, ILDKEGIDY, ILELA, LLQLEAIR, LPVP, LQALHQGQIV, MPVQA and SPVVPF) were identified in camel milk proteins hydrolysed with trypsin. This was achieved using a sequential approach combining liquid chromatography tandem mass spectrometry (LC-MS/MS), qualitative/quantitative structure activity relationship (QSAR) and confirmatory studies with synthetic peptides. The most potent camel milk protein-derived DPP-IV inhibitory peptides, LPVP and MPVQA, had DPP-IV half maximal inhibitory concentrations (IC 50 ) of 87.0 ± 3.2 and 93.3 ± 8.0 µM, respectively. DPP-IV inhibitory peptide sequences identified within camel and bovine milk protein hydrolysates generated under the same hydrolysis conditions differ. This was linked to differences in enzyme selectivity for peptide bond cleavage of camel and bovine milk proteins as well as dissimilarities in their amino acid sequences. Camel milk proteins contain novel DPP-IV inhibitory peptides which may play a role in the regulation of glycaemia in humans. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The object of this study was to assess the prevalence and correlates of the DSM-IV diagnosis of hypochondriasis in a primary care setting. A large sample (N = 1456) of primary care users was given a structured interview to make diagnoses of mood, anxiety, and somatoform disorders and estimate levels of disability. The prevalence of hypochondriasis (DSM-IV) was about 3%. Patients with this disorder had higher levels of medically unexplained symptoms (abridged somatization) and were more impaired in their physical functioning than patients without the disorder. Of the various psychopathologies examined, major depressive syndromes were the most frequent among patients with hypochondriasis. Interestingly, unlike somatization disorder, hypochondriasis was not related to any demographic factor. Hypochondriasis is a relatively rare condition in primary care that is largely separable from somatization disorder but seems closely intertwined with the more severe depressive syndromes.

    Generating the contribution of the International VLBI Service (IVS) to the next ITRF (ITRF2013 or ITRF2014) was the main task of the IVS Combination Center at the Federal Agency for Cartography and Geodesy (BKG, Germany) in 2014. Starting with the ITRF2005, the IVS contribution to the ITRF is an intra-technique combined solution using multiple individual contributions from different institutions. For the upcoming ITRF ten international institutions submitted data files for a combined solution. The data files contain 24h VLBI sessions from the late 1970s until the end of 2014 in SINEX file format containing datum free normal equations with station coordinates and Earth Orientation Parameters (EOP). All contributions have to meet the IVS standards for ITRF contribution in order to guarantee a consistent combined solution. In the course of the generation of the intra-technique combined solution, station coordinate time series for each station as well as a Terrestrial Reference Frame based on the contributed VLBI data (VTRF) were generated and analyzed. Preliminary results using data until the end of 2013 show a scaling factor of -0.47 ppb resulting from a 7-parameter Helmert transformation of the VTRF w.r.t. ITRF2008, which is comparable to the scaling factor that was determined in the precedent ITRF generation. An internal comparison of the EOPs between the combined solution and the individual contributions as well as external comparisons of the EOP series were carried out in order to assure a consistent quality of the EOPs. The data analyses, the combination procedure and results of the combined solution for station coordinates and EOP will be presented.

    Sandia National Laboratories has developed, designed and operated fast burst reactors for over 20 years. These reactors have been used for a variety of radiation effects programs. During this period, programs have required larger irradiation volumes primarily to expose complex electronic systems to postulated threat environments. As experiment volumes increased, a new reactor was built so that these components could be tested. The Sandia Pulse Reactor-IV is a logical evolution of the two decades of fast burst reactor development at Sandia

    The hydrous polymer chemistry of Pu(IV) in aqueous nitric acid solutions has been a subject of considerable interest for several years. This interest stems mainly from the fact that most nuclear fuel reprocessing schemes based on the Purex process can be hampered by the occurrence of polymer. As a result, an understanding and control of the parameters that affect polymer formation during reprocessing are studied. 2 refs

  4. Type IV neonatal Bartter syndrome complicated with congenital chloride diarrhea.

    2012-01-01

    Pseudo-Bartter syndrome encompasses a heterogenous group of disorders similar to Bartter syndrome. Sometimes a few status may be nested, as in our case presented here. An 8-month-old boy was referred to our hospital with of intractable diarrhea, polyuria, persistent hypokalemia, abdominal distension and failure to thrive. He was born in the 34 6/7 gestational week (GW) to consanguineous parents. In the 30(th) GW polyhydramnios was verified by ultrasonography. The laboratory results showed hypokalemic-hypochloremic metabolic alkalosis, hyponatremia, and increased urinary loss of chloride, potassium and calcium. An audiogram test revealed complete sensorineural deafness. Ultrasonography revealed medullary nephrocalcinosis in both kidneys. Elevated plasma renin activity and aldosterone were found and a provisional diagnosis of type-IV neonatal Bartter syndrome was made. Treatment with indomethacin, spironolactone and additional intake of NaCl/KCl was initiated. Despite these therapies, the child's diarrhea persisted but serum potassium concentration normalized, and hypercalciuria and urine output reduced. After determining the high fecal chloride concentration, there was an immediate decompensation of the disease on indomethacin withdrawal, thus a diagnosis of type IV neonatal Bartter syndrome complicated with congenital chloride diarrhea was considered. Indomethacin, spironolactone and supplementary therapies with NaCl/KCl were continued, which resulted in the normalization of serum electrolytes as well as his physical development, but high contents of chloride in urine and faeces and nephrocalcinosis remains unchanged during 1-year follow-up. Because of the clinical and laboratory simulations between the various diseases that lead to hypokalemic-hypochloremic metabolic alkalosis, patients must be evaluated carefully.

  5. Ionizing radiation risk assessment, BEIR IV

    International Nuclear Information System (INIS)

    1991-10-01

    This report of the Subpanel discusses the potential impact on Federal agencies and indicates individual risk factors that could be used by them in risk assessment. The approach used in this CIRRPC report was to consider the risk factors presented in BEIR IV for each radionuclide (or group radioelements) and to make some judgments regarding their validity and/or the uncertainties involved. The coverage of Radon-222 and its progeny dominated the BEIR IV report and this Subpanel felt is was proper to devote more attention to this radionuclide family. This risk factor presented in BEIR IV for radon is 350 cancer deaths per million person-working level months (WLM) of exposure for a lifetime. There is a range of opinions on the conversion from WLM to absorbed dose. As discussed in the text, the use of the WLM concept makes it difficult or infeasible to compare the risk factor for radon with that of other radionuclides which are based on organ dose. This report also includes a discussion of certain fundamental scientific and operational issues that may have decisive effect upon risk factor selection. These adjunct items are dealt with under separate headings and include discussions of threshold dose considerations, extrapolation to low doses, and age at exposure

    2014-01-01

    The spectrum of three-times ionized bromine Br IV has been studied in the 319–2350 Å wavelength region. The spectrum was recorded on a 3-m normal incidence vacuum spectrograph at the St. Francis Xavier University, Antigonish (Canada) and 6.65-m grazing incidence spectrograph at the Zeeman laboratory (Amsterdam). The light sources used were a triggered spark and sliding spark, respectively. The ground configuration of Br IV 3d 10 4s 2 4p 2 , the excited configurations 3d 10 4s4p 3 +3d 10 4s 2 4p (4d+5d+6d+5s+6s+7s) in the odd parity system and 3d 10 4s 2 4p (5p+4f+5f)+3d 10 4s4p 2 (4d+5s)+3d 10 4p 4 in the even parity system have been studied. Relativistic Hartree–Fock (HFR) and least squares fitted (LSF) parametric calculations were used to interpret the observed spectrum. 120 Levels of Br IV have now been established, 58 being new. Among 424 spectral lines, 277 are newly classified. The levels 4s4p 35 S 2 , 4s 2 4p4d 3 F 4 and 4p5p ( 3 P 0,1 , 3 D 1,2 , 3 S 1 ) are revised. We estimate the accuracy of our measured wavelength for sharp and unblended lines to be ±0.005 Å. The ionization limit is determined as 385,390±100 cm −1 (47.782±0.012 eV). -- Highlights: • The spectrum of Br was recorded on a 3-m spectrograph with triggered spark source. • Atomic transitions for Br IV were identified to established new energy levels. • CI calculations with relativistic corrections were made for theoretical predictions. • Weighted oscillator strength (gf) and transition probabilities (gA) were calculated. • Ionization potential of Br IV was determined experimentally

    Full Text Available The objective of this study was to produce artificial antigens for astragaloside IV that could be used to prepare antibodies against astragaloside IV screened in Radix astragali (Astragalus membranaceus (Fisch Bunge, Fabaceae and its preparations, using an indirect ELISA. Astragaloside IV was coupled to carrier proteins, bovine serum albumin and ovalbumin using the sodium periodate method and was then evaluated using SDS-PAGE, MALDI-TOF MS and animal immunizations. The coupling ratio of astragaloside IV to bovine serum albumin ratio was determined to be thirteen, and the indirect ELISA demonstrated that three groups of mice immunized with astragaloside IV-bovine serum albumin produced anti-astragaloside IV- bovine serum albumin-specific antibody, with a minimum serum titer of 1:9600. A method for synthesizing highly immunogenic astragaloside IV artificial antigens was successfully developed thus indicating its feasibility in the establishment of a fast immunoassay for astragaloside IV content determination in Radix astragali and its products.

    Young, P. R.; Keenan, F. P.; Milligan, R. O.; Peter, H.

    2018-04-01

    Solar spectra of ultraviolet bursts and flare ribbons from the Interface Region Imaging Spectrograph (IRIS) have suggested high electron densities of > {10}12 cm‑3 at transition region temperatures of 0.1 MK, based on large intensity ratios of Si IV λ1402.77 to O IV λ1401.16. In this work, a rare observation of the weak O IV λ1343.51 line is reported from an X-class flare that peaked at 21:41 UT on 2014 October 24. This line is used to develop a theoretical prediction of the Si IV λ1402.77 to O IV λ1401.16 ratio as a function of density that is recommended to be used in the high-density regime. The method makes use of new pressure-dependent ionization fractions that take account of the suppression of dielectronic recombination at high densities. It is applied to two sequences of flare kernel observations from the October 24 flare. The first shows densities that vary between 3× {10}12 and 3× {10}13 cm‑3 over a seven-minute period, while the second location shows stable density values of around 2× {10}12 cm‑3 over a three-minute period.

    Full Text Available A traça Phthorimaea operculella (Zeller é considerada atualmente uma das principais pragas da batata. O uso de resistência varietal para controle desse inseto é uma alternativa promissora, mas que ainda precisa ser melhor pesquisada. A resistência de genótipos de batata à traça foi avaliada, em condições de laboratório, analisando-se o efeito de folhas e tubérculos sobre a biologia do inseto. Comparou-se também o desenvolvimento da traça em folhas de batata e tomate. Os experimentos foram conduzidos com os clones de batata NYL 235-4 e N 140-201 (ambos com tricomas glandulares tipo A nas folhas, as cultivares Aracy, Apuã e Itararé e a cultivar de tomate Santa Clara. Os insetos foram criados em folíolos e tubérculos dos genótipos, avaliando-se a duração e a viabilidade das fases larval e pupal e o peso de pupas. O desenvolvimento do inseto não foi afetado nas folhas dos genótipos de batata, mesmo nos materiais com tricomas glandulares. Entretanto, em folhas de tomate houve aumento do período larval e diminuição do peso de pupas, sendo este substrato menos favorável ao desenvolvimento da traça quando comparado às folhas de batata. Em testes com tubérculos, o clone NYL 235-4 apresentou resistência a P. operculella, provocando redução significativa na viabilidade larval e alongamento desta fase. O clone N 140-201 afetou o desenvolvimento do inseto de forma menos pronunciada, alongando a fase larval.

    The spectrum of three-times ionized bromine Br IV has been studied in the 319-2350 Å wavelength region. The spectrum was recorded on a 3-m normal incidence vacuum spectrograph at the St. Francis Xavier University, Antigonish (Canada) and 6.65-m grazing incidence spectrograph at the Zeeman laboratory (Amsterdam). The light sources used were a triggered spark and sliding spark, respectively. The ground configuration of Br IV 3d104s24p2, the excited configurations 3d104s4p3+3d104s24p (4d+5d+6d+5s+6s+7s) in the odd parity system and 3d104s24p (5p+4f+5f)+3d104s4p2 (4d+5s)+3d104p4 in the even parity system have been studied. Relativistic Hartree-Fock (HFR) and least squares fitted (LSF) parametric calculations were used to interpret the observed spectrum. 120 Levels of Br IV have now been established, 58 being new. Among 424 spectral lines, 277 are newly classified. The levels 4s4p35S2, 4s24p4d 3F4 and 4p5p (3P0, 1, 3D1, 2, 3S1) are revised. We estimate the accuracy of our measured wavelength for sharp and unblended lines to be ±0.005 Å. The ionization limit is determined as 385,390±100 cm-1 (47.782±0.012 eV).

    We report herein the synthesis and characterization of several imine complexes of tetravalent thorium (Th(IV)) and uranium (U(IV)). The ligands investigated in this study are a Schiff base type, including the well-known salen ligand (H{sub 2}Le, Fig. 1). The complexation in solution was investigated by NMR measurements indicating paramagnetic effects of unpaired f-electrons of U(IV) on the ligand molecule. We also determined the solid-state molecular structures of the synthesized complexes by single crystal X-ray diffraction. The synthesized complexes show an eight-fold coordination geometry around the actinide center surrounded by two tetradentate ligands with 2N- and 2O-donor atoms.

  13. The kinetics of the cerium(IV)-uranium(IV) reaction at low sulfate concentrations

    Michaille, P.; Kikindai, T.

    1977-01-01

    The rate of oxidation of uranium(IV) by cerium(IV) was measured with a stopped-flow spectrophotometer at sulfuric acid concentrations of 2 x 10 -6 to 0.5 M. At a constant hydrogen ion concentration of 0.5 M, the maximum rate constant was observed for 2 x 10 -3 M sulfuric acid; at that concentration, two sulfate ions were involved in the activated complex. The dependence of the rate constant on the hydrogen ion concentration showed that the reaction paths involving one or two sulfate ions also involved one hydroxyl ion, whereas one hydrogen ion was involved in the five sulfate dependent path. Spectrophotometric measurements supported the existence of a hydrolyzed monosulfatocomplex of cerium(IV). (author)

  2. Topological characterisation and identification of critical domains within glucosyltransferase IV (GtrIV of Shigella flexneri

    2011-12-01

    Full Text Available Abstract Background The three bacteriophage genes gtrA, gtrB and gtr(type are responsible for O-antigen glucosylation in Shigella flexneri. Both gtrA and gtrB have been demonstrated to be highly conserved and interchangeable among serotypes while gtr(type was found to be specific to each serotype, leading to the hypothesis that the Gtr(type proteins are responsible for attaching glucosyl groups to the O-antigen in a site- and serotype- specific manner. Based on the confirmed topologies of GtrI, GtrII and GtrV, such interaction and attachment of the glucosyl groups to the O-antigen has been postulated to occur in the periplasm. Results In this study, the topology of GtrIV was experimentally determined by creating different fusions between GtrIV and a dual-reporter protein, PhoA/LacZ. This study shows that GtrIV consists of 8 transmembrane helices, 2 large periplasmic loops, 2 small cytoplasmic N- and C- terminal ends and a re-entrant loop that occurs between transmembrane helices III and IV. Though this topology differs from that of GtrI, GtrII, GtrV and GtrX, it is very similar to that of GtrIc. Furthermore, both the N-terminal periplasmic and the C-terminal periplasmic loops are important for GtrIV function as shown via a series of loop deletion experiments and the creation of chimeric proteins between GtrIV and its closest structural homologue, GtrIc. Conclusion The current study provides the basis for elucidating the structure and mechanism of action of this important O-antigen modifying glucosyltransferase.

    1987-11-01

    Niobium cannot be separated from zirconium or hafnium when these elements occur together in solution with common anions such as Cl- and SO 4 --. This is ascribed to the copolymerisation of Nb v and the hydrolyzed ionic species of Zr IV v and Hf IV by which the colloidal particles are masked as Zr- and Hf-compounds. In HCl the particles are positively charged as opposed to when they are in sulphate solution where the Zr- and Hf- sulphate complexes confer a negative charge. The two cases are considered separately. (author)

    I will describe the current plans for a next generation sky survey that will begin After SDSS-IV --- AS4. AS4 will be an unprecedented all-sky spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way galaxy, trace the emergence of the chemical elements, reveal the inner workings of stars, the growth of black holes, and investigate the origin of planets. It will provide the most comprehensive all-sky spectroscopy to multiply the science from the Gaia, TESS and eROSITA missions. AS4 will also create a contiguous spectroscopic map of the interstellar gas in the Milky Way and nearby galaxies that is 1,000 times larger than the state of the art, uncovering the self-regulation mechanisms of Galactic ecosystems. It will pioneer systematic, spectroscopic monitoring across the whole sky, revealing changes on timescales from 20 minutes to 20 years. The project is now developing new hardware to build on the SDSS-IV infrastructure, designing the detailed survey strategy, and actively seeking to complete its consortium of institutional and individual members.

    1993-11-01

    The ARIES-IV Nested Shell Blanket (NSB) Design is an alternate blanket concept of the ARIES-IV low activation helium-cooled reactor design. The reference design has the coolant routed in the poloidal direction and the inlet and outlet plena are located at the top and bottom of the torus. The NSB design has the high velocity coolant routed in the toroidal direction and the plena are located behind the blanket. This is of significance since the selected structural material is SiC-composite. The NSB is designed to have key high performance components with characteristic dimensions of no larger than 2 m. These components can be brazed to form the blanket module. For the diverter design, we eliminated the use of W as the divertor coating material by relying on the successful development of the gaseous divertor concept. The neutronics and thermal-hydraulic performance of both blanket concepts are similar. The selected blanket and divertor configurations can also meet all the projected structural, neutronics and thermal-hydraulics design limits and requirements. With the selected blanket and divertor materials, the design has a level of safety assurance rate of I (LSA-1), which indicates an inherently safe design

    2015-09-01

    In this paper, we consider two hospitals with different perceived quality of care competing to capture a fraction of the total market demand. Patients select the hospital that provides the highest utility, which is a function of price and the patient's perceived quality of life during their life expectancy. We consider a market with a single class of patients and show that depending on the market demand and perceived quality of care of the hospitals, patients may enjoy a positive utility. Moreover, hospitals share the market demand based on their perceived quality of care and capacity. We also show that in a monopoly market (a market with a single hospital) the optimal demand captured by the hospital is independent of the perceived quality of care. We investigate the effects of different parameters including the market demand, hospitals' capacities, and perceived quality of care on the fraction of the demand that each hospital captures using some numerical examples.

Após períodos pré-estabelecidos, a câmara foi aberta e os queijos foram pesados e secionados, de modo a permitir a determinação da distribuição de sal no interior dos mesmos pelo método de Mohr. A salga por IV permitiu a obtenção de queijos com 1,6% em massa de sal em 15 minutos, contra 2,5 horas da salga convencional. Além disso, a distribuição de sal nos queijos salgados por IV foi mais homogênea do que nos queijos salgados por imersão em salmoura a pressão atmosférica. Esses resultados indicaram que a salga de queijos tipo Minas por IV pode ser uma boa alternativa de processamento, tanto do ponto de vista econômico como tecnológico.Minas cheese salting by vacuum impregnation was studied using cylindrical cheese samples of about 500 g and 120 ' 60mm (radius ' height, that were immersed in a hermetic chamber with 22g NaCl/100g, where sub-atmospheric pressures were applied. The essays were performed after the press stage, used in this to obtain more compact cheeses and facilitate the reproducibility of an average cheese pore structure. Vacuum intensity of 85.3kPa (absolute pressure of 16kPa was applied intermittently, interleaving with the atmospheric pressure recuperation in the chamber. After pre-determined periods, the chamber was opened and the cheeses were weighed and cut, in order to determine the salt concentration distributions, by means of a modified Mohr

    Dipeptidyl peptidase IV (DPP-IV) is a promising Type 2 diabetes mellitus (T2DM) drug target. DPP-IV inhibitors prolong the action of glucagon-like peptide-1 (GLP-1) and gastric inhibitory peptide (GIP), improve glucose homeostasis without weight gain, edema, and hypoglycemia. However, the marketed DPP-IV inhibitors have adverse effects such as nasopharyngitis, headache, nausea, hypersensitivity, skin reactions and pancreatitis. Therefore, it is still expected for novel DPP-IV inhibitors with minimal adverse effects. The scaffolds of existing DPP-IV inhibitors are structurally diversified. This makes it difficult to build virtual screening models based upon the known DPP-IV inhibitor libraries using conventional QSAR approaches. In this paper, we report a new strategy to predict DPP-IV inhibitors with machine learning approaches involving naïve Bayesian (NB) and recursive partitioning (RP) methods. We built 247 machine learning models based on 1307 known DPP-IV inhibitors with optimized molecular properties and topological fingerprints as descriptors. The overall predictive accuracies of the optimized models were greater than 80%. An external test set, composed of 65 recently reported compounds, was employed to validate the optimized models. The results demonstrated that both NB and RP models have a good predictive ability based on different combinations of descriptors. Twenty "good" and twenty "bad" structural fragments for DPP-IV inhibitors can also be derived from these models for inspiring the new DPP-IV inhibitor scaffold design.

    Health-care costs associated with pressure sores are significant and their financial burden is likely to increase even further. The aim of this study was to analyse the direct medical costs of hospital care for surgical treatment of pressure sores stage III and IV. We performed a retrospective chart study of patients who were surgically treated for stage III and IV pressure sores between 2007 and 2010. Volumes of health-care use were obtained for all patients and direct medical costs were subsequently calculated. In addition, we evaluated the effect of location and number of pressure sores on total costs. A total of 52 cases were identified. Average direct medical costs in hospital were €20,957 for the surgical treatment of pressure sores stage III or IV; average direct medical costs for patients with one pressure sore on an extremity (group 1, n = 5) were €30,286, €10,113 for patients with one pressure sore on the trunk (group 2, n = 32) and €40,882 for patients with multiple pressure sores (group 3, n = 15). The additional costs for patients in group 1 and group 3 compared to group 2 were primarily due to longer hospitalisation. The average direct medical costs for surgical treatment of pressure sores stage III and IV were high. Large differences in costs were related to the location and number of pressure sores. Insight into the distribution of these costs allows identification of high-risk patients and enables the development of specific cost-reducing measures.

    Full Text Available Introduction: Hypertensive retinopathy describes a spectrum of retinal changes in patients with elevated blood pressure (BP. It is unknown why some patients are more likely to develop acute ocular end-organ damage than others with similar BP. We examined risk factors for grade III/IV hypertensive retinopathy among patients with hypertensive urgency in the emergency department (ED and compared healthcare utilization and mortality between patients with and without grade III/IV hypertensive retinopathy.Methods: A preplanned subanalysis of patients who presented to a university hospital ED with diastolic BP > 120 mmHg and who enrolled in the Fundus Photography versus Ophthalmoscopy Trial Outcomes in the ED study was performed. Bilateral nonmydriatic ocular fundus photographs, vital signs, and demographics were obtained at presentation. Past medical history, laboratory values, healthcare utilization, and mortality were ascertained from medical record review at least 8 months after initial ED visit.Results: Twenty-one patients with diastolic BP > 120 mmHg, 7 of whom (33% had grade III/IV hypertensive retinopathy, were included. Patients with retinopathy were significantly younger than those without (median 33 vs 50 years, P = 0.02. Mean arterial pressure (165 vs 163 mmHg was essentially equal in the 2 groups. Patients with retinopathy had substantially increased but nonsignificant rates of ED revisit (57% vs 29%, P = 0.35 and hospital admission after ED discharge (43% vs 14%, P = 0.28. One of the patients with retinopathy died, but none without.Conclusion: Younger patients may be at higher risk for grade III/IV hypertensive retinopathy among patients with hypertensive urgency. Chronic compensatory mechanisms may have not yet developed in these younger patients. Alternatively, older patients with retinopathy may be underrepresented secondary to increased mortality among these patients at a younger age (survivorship bias. Further research is needed to

    We welcome the Eden Mill station in northeastern Maryland to Region IV this year. With three stations reporting their worst year ever, we really need to be refreshed. After a cool and wet July, August was hot and wet in the east. Temperatures in September remained close to normal, but thanks to tropical storms Henri (6-8 Sep) and Isabel (18 Sep), rainfall was excessive in the Chesapeake Bay states. The entire Northeast had cool weather in October, starting with an early freeze on 3 Oct that triggered some good banding days in our region. Precipitation was unusually spotty in October, but plentiful at most of the Region IV stations. November temperatures were consistently well above the norm, starting with a record-breaking 81 ø in Baltimore on the 1st.Four of the five Maryland stations had their best day on 19 or 20 Oct. One might expect some of the Virginia coastal stations, Chincoteague, Kiptopeke, and Back Bay, to share the same best day, but they did not. Three stations reported an increase in birds per net hour this year, while seven had a decline. Summarizing the changes in rank in Table 2, Gray Catbird was the species with the most (5) increases in rank (in excess of decreases), followed by junco (4) and Myrtle Warbler and Swamp Sparrow (3 each). Yellowthroat had the most decreases (5), followed by redstart (3).Myrtle Warbler (4572) was once again the most commonly banded species in Region IV, followed by White-throated Sparrow (1723), Gray Catbird (1349), and Western Palm Warbler (1090). Michelle Davis' station on Key Biscayne is the envy of the rest of us. Her top eight species were all warblers and there was not a Myrtle among them. Imagine having Parula, Prairie, and Worm-eating warblers fighting for sixth place!Not showing among the top ten, however, are other surprises. Several banders commented on Sawwhet Owls and Bicknell's Thrushes. Deanna Dawson banded a Cerulean Warbler at Patuxent. Danny Bystrak caught 138 Swamp Sparrows at Jug Bay. In addition

    2018-05-12

    Goodpasture's (GP) disease is an autoimmune disorder characterized by the deposition of pathogenic autoantibodies in basement membranes of kidney and lung eliciting rapidly progressive glomerulonephritis and pulmonary hemorrhage. The principal autoantigen is the α345 network of collagen IV, which expression is restricted to target tissues. Recent discoveries include a key role of chloride and bromide for network assembly, a novel posttranslational modification of the antigen, a sulfilimine bond that crosslinks the antigen, and the mechanistic role of HLA in genetic susceptibility and resistance to GP disease. These advances provide further insights into molecular mechanisms of initiation and progression of GP disease and serve as a basis for developing of novel diagnostic tools and therapies for treatment of Goodpasture's disease.

    The BCI competition IV stands in the tradition of prior BCI competitions that aim to provide high quality neuroscientific data for open access to the scientific community. As experienced already in prior competitions not only scientists from the narrow field of BCI compete, but scholars with a broad variety of backgrounds and nationalities. They include high specialists as well as students. The goals of all BCI competitions have always been to challenge with respect to novel paradigms and complex data. We report on the following challenges: (1) asynchronous data, (2) synthetic, (3) multi-class continuous data, (4) session-to-session transfer, (5) directionally modulated MEG, (6) finger movements recorded by ECoG. As after past competitions, our hope is that winning entries may enhance the analysis methods of future BCIs. PMID:22811657

    Titanium can exist in solution in a number of oxidation states. The titanium(IV) exists in acidic solutions as the oxo-cation, TiO 2+ , rather than Ti 4+ . Zirconium is used in the ceramics industry and in nuclear industry as a cladding material in reactors where its reactivity towards hydrolysis reactions and precipitation of oxides may result in degradation of the cladding. In nature, hafnium is found together with zirconium and as a consequence of the contraction in ionic radii that occurs due to the 4f -electron shell, the ionic radius of hafnium is almost identical to that of zirconium. All isotopes of thorium are radioactive and, as a consequence of it being fertile, thorium is important in the nuclear fuel cycle. The polymeric hydrolysis species that have been reported for thorium are somewhat different to those identified for zirconium and hafnium, although thorium does form the Th 4 (OH) 8 8+ species.

    Because of advances in CT and MR imaging, accurate identification and evaluation of cranial nerve lesions is now possible. Cranial nerves III, IV, and VI, providing motor and sensory control of the eye, can be evaluated as a unit. In this paper, the authors present an overview of the anatomy and pathology of these cranial nerves. We first illustrate their normal anatomic pathways from the brain stem to the orbit. This is followed by clinical examples of patients with a variety of isolated and complex palsies of these three cranial nerves. This is accomplished by inclusion of ocular photographs, correlative imaging studies, and the use of diagrams. Knowledge of the gross and imaging anatomy and the ophthalmologic manifestations of pathology affecting these three cranial nerves permits a tailored approach to their evaluation

    2010-09-01

    Full Text Available The SnIV atom in the title organotin dithiocarbamate, [Sn(C6H52(C11H14NS2Cl], is penta-coordinated by an asymmetrically coordinating dithiocarbamate ligand, a Cl and two ispo-C atoms of the Sn-bound phenyl groups. The resulting C2ClS2 donor set defines a coordination geometry intermediate between square-pyramidal and trigonal-bipyramidal with a slight tendency towards the latter. The formation of close intramolecular C–H...Cl and C–H...S contacts precludes the Cl and S atoms from forming significant intermolecular contacts. The presence of C–H...π contacts leads to the formation of supramolecular arrays that stack along the b axis.

    LHCb is a dedicated heavy flavour physics experiment that operates at the LHC. The LHCb collaboration plans to change key features of the present detectors for Run III, moving to a full detector readout at 40MHz and operating at a luminosity of 1-2x1033cm-2s-1. The new Vertex Locator (VELO) detector will use hybrid pixel detectors composed of silicon sensors bump-bonded to new VeloPix CMOS readout chips designed for the new 40MHz readout rate. We will present a novel way of delivering bias through the ASIC backside in order to test IV characteristics of sensors in vacuum before module construction. The appropriate laboratory setups developed to test VELO hybrids for production will also be discussed.

    Closure of tubular patent ductus arteriosus remains a challenging procedure. Anecdotal use of Amplatzer Vascular Plug IV for tubular ductus closure has been reported but feasibility and safety in a consecutive patients' series remain unknown. We performed a monocenter prospective study at the Marie Lannelongue Hospital in Paris, France. From 2009 to 2014, a total of 47 patients (39 infants, 3 children, and 5 adults) underwent ductus closure with the Plug IV. Ductus morphology was a type E in 34 (72.3%) patients and a type C in 13 (27.7%) patients. Ductus closure occurred in 39 (83.0%) infants at a median age of seven months (range: 3-23 months) and a median weight of 6.9 kg (range: 4.1-17.0 kg). A past history of prematurity and very low birth weight was found in 33 (70.2%) of them. Twelve (25.5%) patients had pulmonary hypertension. Mean Plug IV diameter was 1.9 ± 0.1 mm larger than the mean maximal ductus diameter. Early complete closure of the ductus was obtained in all patients. Early migration of an undersized Plug IV occurred in one (2.1%) patient and was suitable for percutaneous device retrieval. After a mean follow-up of 3.4 ± 1.4 years, all patients are alive and asymptomatic, no late complication occurred. Transcatheter closure of tubular ductus with the Amplatzer Vascular Plug IV can be safe and effective, with a 100% early occlusion rate. This device, suitable for a 4F sheath, is a new alternative for tubular ductus closure in low-body-weight infants. © The Author(s) 2014.

  12. The Elegy in the Aeneid Book IV

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available In Aeneid’s book IV, Virgil makes use of elegiac topics while narrating Dido and Aeneas’ ill-fated love, inserting these topics into the epic genre. Some key characteristics of elegiac lover, such as the furor by which he is taken when injured by Cupid’s dart; lover’s idleness; the mala fama that emerges from the love affair; and, lastly, the misera condition in which the lover is thrown to, always followed by a lament; all these has shown to be present in Aeneid’s book IV. So, in addition to evincing how epic genre, without losing its formal rigour, subsume other genres, in this case the elegiac one, this article observes how this procedure takes part in both Vergil’s intra-narrative and extra-narrative purpose when composing Aeneid. In the first case, if we bear in mind that books I to VI are concerned with the construction of Aeneas’ heroic ἦθος, the hero’s denial in staying together with the queen confirms, once again, his destiny, which is Rome’s foundation, that is conventionally of an epic hero – and not of an elegiac lover. As for the second one, it is first important to be aware of Vergil’s aim when composing Aeneid, which is to insert Rome’s history into a myth, which is the elegiac poem itself. Therefore, Dido’s abandonment and her following imprecation in verses 590-640 are used by the poet to justify, even if ironically, Carthaginians’ rivalry and violence against Romans throughout the Punic Wars, putting them as the result of a woman’s love frustration.

    1990-10-01

    A user almost always faces a big problem when having to learn to use a new computer system. The information necessary to use the system is often scattered throughout many different manuals. The user also faces the problem of extracting the information really needed from each manual. Very few computer vendors supply a single Users Guide or even a manual to help the new user locate the necessary manuals. Modcomp is no exception to this, Modcomp MAX IV requires that the user be familiar with the system file usage which adds to the problem. At General Atomics there is an ever increasing need for new users to learn how to use the Modcomp computers. This paper was written to provide a condensed Users Reference Guide'' for Modcomp computer users. This manual should be of value not only to new users but any users that are not Modcomp computer systems experts. This Users Reference Guide'' is intended to provided the basic information for the use of the various Modcomp System Processors necessary to, create, compile, link-edit, and catalog a program. Only the information necessary to provide the user with a basic understanding of the Systems Processors is included. This document provides enough information for the majority of programmers to use the Modcomp computers without having to refer to any other manuals. A lot of emphasis has been placed on the file description and usage for each of the System Processors. This allows the user to understand how Modcomp MAX IV does things rather than just learning the system commands.

    Eighteen new mono-organotin dithiocarbamate compounds derived each nine from methyltin(IV) and phenyltin(IV) reacted using in-situ method with various type of N-dialkylamine together with carbon disulphide with the ratio of 1:3:3. Elemental and gravimetric analysis showed that the general formula of these compounds were RSnCl[S 2 CNR′R″] 2 (R= Ph, CH 3 , R′ = CH 3 , C 2 H 5 , C 7 H 7 and R″ = C 2 H 5 , C 6 H 11 , iC 3 H 7 , C 7 H 7 ). These compounds had been characterized by infrared spectroscopy, ultraviolet spectroscopy, 1 H, 13 C NMR spectroscopy and single crystal X-ray crystallography. The infrared spectra of these compounds showed three important peaks indicating the formation of dithiocarbamate compounds, ν(C N), ν(C S) and ν(Sn-S) band which present in the region of 1444–1519, 954–1098 and 318–349 cm −1 respectively. The ultraviolet-visible spectra showed an absorption band for the π - π* transition of N C S group in the range of 253 – 259 nm due to the intramolecular charge transfer of the ligand. The 13 C NMR spectra showed an important shift for δ(N 13 CS 2 ) in the range of 196.8 – 201.9 ppm.. Single crystal X-ray diffraction studies showed three new structures with the general formula of PhSnCl[S 2 CN(Et)(i−Pr)] 2 , MeSnCl[S 2 CN(Me)(Cy)] 2 and MeSnCl[S 2 CN(i−Pr)(CH 2 Ph)] 2 . All structures having a distorted octahedral geometry set by CClS 4 donor atom from the two chelating dithiocarbamate ligands

  17. Financiarización del tipo de cambio en México y la actividad productiva

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Existe una estrecha relación entre el fortalecimiento del proceso de financiarización y la gestión de las diferentes monedas. Dicha relación aparece cuando en los espacios monetarios locales se abandona la demanda de moneda nacional en beneficio de alguna otra moneda o cualquier objeto especulativo. Se trata de una política económica a favor del beneficio financiero. En la gestión de las monedas locales, se impone la nueva norma de las altas finanzas: remuneración elevada, inflación escasa. El tipo de cambio en México está en función de las condiciones de confianza y rentabilidad del beneficio financiero. Las fluctuaciones en el tipo de cambio se convirtien en un factor determinante de las variaciones experimentadas por los flujos de tesorería, las ventas, los beneficios y los activos de las grandes empresas dedicadas a la actividad productiva cotizados en diversas monedas. Lo anterior se traduce en un atractivo para el capital monopolista ­financiero local, pues significa no sólo mantener su riqueza financiera y recibir íntegramente sus intereses, sino que también verse premiadas con un beneficio financiero, en su propia moneda. La certidumbre relativa sobre la evolución del tipo de cambio en la economía mexicana es una acción necesaria para que un sector importante de las grandes empresas relacionadas al capital – monopolista financiero mantenga sus condiciones de rentabilidad.

    Full Text Available Objetivo: Estimar el coste de la atención sanitaria al paciente diabético tipo 2, diferenciando el gasto derivado del control de la enfermedad, de la atención de sus complicaciones y de otros costes directos asociados. Métodos: Recogida retrospectiva del consumo de recursos a partir de la historia clínica y la entrevista personal en 29 centros de atención primaria de todo el territorio nacional de una muestra de pacientes seleccionados de forma aleatoria a partir del registro de diabéticos de cada centro. Resultados: Se evaluó a 1.004 pacientes (561 mujeres con una media de edad de 67,42 años y una media de evolución de la enfermedad de 10,07 años. El 50,9% no presentaba complicaciones, el 17,7% sólo macrovasculares, el 19,5% sólo microvasculares y el 11,9% ambas. El coste anual sanitario por paciente fue de 1.305,15 euros. De este coste el 28,6% (373,27 euros estaba relacionado directamente con el control de la diabetes, el 30,51% (398,20 euros con sus complicaciones y el 40,89% (533,68 euros no estaba relacionado. El coste medio de un paciente sin complicaciones fue de 883 euros frente a 1.403 de un paciente con complicaciones microvasculares, 2.022 cuando existían complicaciones macrovasculares y 2.133 cuando coexistían ambos tipos de complicaciones. Conclusiones: El elevado coste del tratamiento de la diabetes tipo 2 y sus complicaciones, sugiere la posibilidad de que la mejora del control de la enfermedad pueda no sólo mejorar la supervivencia y la calidad de vida, sino reducir los costes asociados con las complicaciones crónicas.

    The first supports for transmission power lines were relatively small structures, of simple configuration, to save reduced clearances to resist load in accordance with its need; with the technical development, gradually appeared higher and higher electric tensions and greater obstacles to overcome, consequently the design of the supports had to be adapted to the new conditions. This gave rise to the development of a specific technique that would adequate and incorporate the continuous engineering advances. In this document the initial considerations on the design poles pipe type are examined; within these considerations mention is made of: the design, the manufacture, the prototype tests, installation, quality control and foundations. The type tube pole is portrayed, as well as the steel reinforcement, finally the types of precast foundations are shown [Espanol] Los primeros soportes para lineas de transmision fueron estructuras relativamente pequenas, de configuracion simple, para salvar claros reducidos y resistir cargas proporcionales a sus necesidades, con el desarrollo de la tecnica, fueron apareciendo tensiones electricas cada vez mas elevadas y obstaculos mayores que vencer, por lo que el diseno de los soportes tuvo que adaptarse a las nuevas condiciones. Esto dio origen al desenvolvimiento de una tecnica especifica que fuese adecuando e incorporando los continuos avances de la ingenieria. En este documento se tratan las consideraciones iniciales del diseno de los postes tipo tubo; dentro de estas consideraciones se citan: el diseno, la fabricacion, las pruebas de prototipo, montajes, control de calidad y cimentaciones. Se ilustra el poste tipo tubo, al igual que el armado del poste, por ultimo se muestra los tipos de cimentaciones precoladas

    Full Text Available Este artículo presenta una aplicación eficiente de un control por modelo de referencia sobre un robot de tipo SCARA. El control estudiado es un control predictivo funcional, el que hace uso de un modelo dinámico simplificado del robot. Los ensayos simulados se realizan sobre un robot de cuatro grados de libertad, tipo SCARA. Con el fin de comparar diferentes estrategias de control, se diseña un controlador clásico tipo PID y dos controladores basados en el modelo de referencia. En este último caso el sistema se linealiza y se desacoplada por realimentación, lo que transforma el sistema a controlar en un simple par de integradores. Al sistema lineal y desacoplado resultante se le aplica el control por par calculado y el control predictivo funcional. Los tres controladores estudiados se simulan sobre el robot SCARA con valores numéricos reales. Las pruebas permiten valorar las respuestas de estos controladores en seguimiento de trayectoria, rechazo de perturbaciones y presencia de errores en el modelado con consignas complejas similares a las utilizadas en procesos de fabricación.This paper describes an efficient approach for model based control, applied on a SCARA robot. The studied control is the predictive functional control which uses a simplified dynamical model of the robot. The simulated tests are made on a SCARA type robot, with four DOF. To compare several control strategies, a classical PID control and two model based controllers are designed. In the last case, the model is first linearized and decoupled by feedback, transforming the system into a double set of integrators. Computed torque control and predictive functional control are applied to the linear and decoupled system. The three studied controllers are simulated on the SCARA robot with real numerical values. Tracking performance, disturbance rejection and model robot mismatch are enlightened, using complex machining tasks trajectories and error presence in the modelling

    Full Text Available OBJETIVO: Abordar os aspectos práticos da realização segura de atividade física e esportes em crianças e adolescentes portadores de diabetes tipo 1. FONTES DOS DADOS: A pesquisa dos artigos foi conduzida em fontes de dados nacionais (SciELO e internacionais (PubMed/MEDLINE, assim como nas próprias referências dos artigos encontrados, adotando como limites: artigos publicados nos últimos 10 anos, preferencialmente conduzidos em crianças e adolescentes com diabetes tipo 1, sendo em sua maioria estudos experimentais e meta-análises sobre atividade física. SÍNTESE DOS DADOS: Com o metabolismo aeróbico, os músculos esqueléticos consomem maior quantidade de glicose para gerar energia, o que diminui a gliconeogênese hepática, levando a uma diminuição na glicemia e aumentando o risco de hipoglicemia. A reposição de carboidratos antes, durante e após o exercício em quantidade adequada e a redução da dose de insulina de ação rápida (pré-refeição são os principais aliados da criança e adolescente com diabetes tipo 1 para evitar a ocorrência da hipoglicemia severa. CONCLUSÕES: Para a reposição de carboidratos e a redução da dose de insulina, deve-se considerar o tipo, a duração e a intensidade da atividade física, bem como o horário de sua realização. A participação em diversos esportes, coletivos e individuais, e em atividades físicas de intensidades variadas é possível, sendo muito recomendado no tratamento do diabetes infantil.

A origem dos choques associados a essasemissões é ainda uma questão em aberto da física solar. Enquanto alguns trabalhos sugerem os flares solarescomo seus acionadores, outros fornecem indícios de serem as ejeções de massa coronal (CMEs sua origemmais provável. Este trabalho apresenta os resultados da análise de duas emissões tipo II, registradas por doisespectrômetros da rede e-CALLISTO (extended-Compound Astronomical Low-cost Low-frequency Instrument forSpectroscopy and Transportable Observatory, os quais operam na faixa de frequências de 45-870 MHz. Oprimeiro evento, observado em 13 de junho de 2010, às 05:38 UT, apresentou uma taxa de deriva em frequênciade -0,2 MHz s-1, correspondente a uma velocidade de choque de 528 km s-1, estando, temporalmente, associadoa uma CME lenta (~320 km s-1 e a um flare solar em raios-X, classe M1.0. O segundo evento, observado em 09de Agosto de 2011, às 08:02 UT, apresentou uma taxa de deriva em frequência de -1,4 MHz s-1, correspondentea uma velocidade de choque de 1375 km s-1, estando, temporalmente, associado a uma CME tipo halo (~1610km s-1 e a um flare solar em raios-X, classe X6.9. Os resultados obtidos, para os parâmetros observacionais dasemissões tipo II e para os parâmetros físicos de suas fontes, são discutidos no contexto de sua relação com seuflares e CMEs associados.

    2008-01-01

    The aim of this study was to focus on the clinical and paraclinical symptoms of patients suffering from Stage IV vestibular schwannomas (VSs). In this prospective study, we included 734 patients who have VS and candidates for operation. Patients were classified as having Stage I, II, III, or IV tumors according to Tos criteria as evaluated by magnetic resonance imaging. PREOPERATIVE CLINICAL EVALUATION: We recorded the occurrence of complaints (%) and duration (yr) of hearing loss, tinnitus, and balance disorder. Preoperative paraclinical evaluation included pure-tone (PTA) and speech audiometry, auditory brainstem response (ABR) patterns, and vestibular deficit at videonystamography (VNG). Continuous variables were compared between Stage IV and other stages using analysis of variance. Qualitative variables expressed as a percentage of presence were compared between Stage IV and other stages using percentage comparison. Quantitative Parameters. Patients with Stage IV VS were significantly younger as compared with patients with other stages. Stage IV hearing loss was greater compared with other stages at 250 and 500 Hz but smaller at 2,000 and 8,000 Hz. We found no difference in the loss of PTA between Stage IV and the other stages. Speech discriminancy score was smaller in Stage IV. The durations of hearing loss, tinnitus, and balance disorders were similar whatever the tumor stage. Auditory brainstem response patterns showed no difference in Wave III latency between Stage IV VS and other stages, whereas Wave V latency and V-I interval were higher in Stage IV. Both ABR threshold and VNG caloric deficit were higher in Stage IV VS compared with other stages. Qualitative Parameters. The percentage of patients with Stage IV was lower than that with Stages II and III. The percentage of men and women was similar in all stages. The occurrence of hearing loss was similar in all stages, whereas that of tinnitus was lower in Stage IV compared with Stages I and II. In

    Full Text Available O estudo em questão visa avaliar a relação entre risco e benefício do uso de tração com halo craniano como alternativa para estabilização nas fraturas-luxações por mecanismo de distração-flexão tipo IV de Allen e Ferguson, considerando a natureza da lesão, seu extenso dano ligamentar e o risco de apresentar distração excessiva e conseqüente lesão da medula espinhal. Para tanto, realizamos uma análise retrospectiva no IOT-HC-FMUSP envolvendo um período de 10 anos, quando 34 casos foram diagnosticados como fratura-luxação por distração-flexão da coluna cervical baixa, sendo 12 deles do tipo IV. Todos foram submetidos à tração esquelética com halo craniano num momento inicial. Durante o controle radiográfico seqüencial, observou-se distração excessiva em sete casos, mesmo com baixo peso inicial (4 kg. Em dois pacientes houve surgimento de nistagmo. Em todos os casos a tração foi retirada e seguiu-se normalização do quadro clínico.This study aims to evaluate the risk/ benefit ratio in the use of traction with cranial halo as an alternative to stabilize fractures-dislocations by Allen & Ferguson's type IV- distraction-flexion mechanism, considering the nature of the injury, its extensive ligament damage and the risk of presenting excessive distraction and resultant spinal cord injury. Thus, we performed a retrospective analysis at IOT-HC-FMUSP comprising a period of 10 years, when 34 cases were diagnosed as fractures-dislocations due to distraction-flexion of the low cervical spine, of which 12 were IV-type. All individuals have been submitted to skeletal traction with cranial halo at an early phase. During sequential X-ray management, an excessive distraction was seen in seven cases, even with initial light weight (4 kg. In two patients, the onset of nistagmus was seen. In all cases, traction was removed, which was followed by stabilization of the clinical picture.

    Extracellular matrix proteins play a crucial role in influencing the invasion of trophoblast cells. However the role of collagens and collagen type IV (col-IV) in particular at the implantation site is not clear. Immunohistochemistry was used to determine the distribution of collagen types I, III, IV and VI in endometrium and decidua during the menstrual cycle and the first trimester of pregnancy. Expression of col-IV alpha chains during the reproductive cycle was determined by qPCR and protein localisation by immunohistochemistry. The structure of col-IV in placenta was examined using transmission electron microscopy. Finally, the expression of col-IV alpha chain NC1 domains and collagen receptors was localised by immunohistochemistry. Col-IV alpha chains were selectively up-regulated during the menstrual cycle and decidualisation. Primary extravillous trophoblast cells express collagen receptors and secrete col-IV in vitro and in vivo, resulting in the increased levels found in decidua basalis compared to decidua parietalis. A novel expression pattern of col-IV in the mesenchyme of placental villi, as a three-dimensional network, was found. NC1 domains of col-IV alpha chains are known to regulate tumour cell migration and the selective expression of these domains in decidua basalis compared to decidua parietalis was determined. Col-IV is expressed as novel forms in the placenta. These findings suggest that col-IV not only represents a structural protein providing tissue integrity but also influences the invasive behaviour of trophoblast cells at the implantation site.

    The stability constants and the enthalpies of formation of thorium(IV)- and uranyl(VI)-malonate complexes have been determined by potentiometric and calorimetric titrations in 1.00 M solutions of Na(ClO/sub 4/) at 25/sup 0/C. All complexes formed are found to be stabilized by a large entropy gain. The values for the stability constants agree with an ionic bonding model. The malonate behaves as a bidentate ligand forming only chelate complexes.

    As a complement to the attached code 3D neutron-CIEMAT thermohydraulic added a module to simulate transient. Temporary kinetics is resolved by factoring flow in a spatial part and another storm. MCNP provides the reactivity and updated spatial function and COBRA-IV calculates the temperature distribution. Temporary dependence of amplitude is calculated using time delayed neutron Kinetic equations. As an example of application, examines a transient loss of flow in MYRRHA, a lead-cooled experimental reactor.

    Eighteen new mono-organotin dithiocarbamate compounds derived each nine from methyltin(IV) and phenyltin(IV) reacted using in-situ method with various type of N-dialkylamine together with carbon disulphide with the ratio of 1:3:3. Elemental and gravimetric analysis showed that the general formula of these compounds were RSnCl[S{sub 2}CNR′R″]{sub 2} (R= Ph, CH{sub 3}, R′ = CH{sub 3}, C{sub 2}H{sub 5}, C{sub 7}H{sub 7} and R″ = C{sub 2}H{sub 5}, C{sub 6}H{sub 11}, iC{sub 3}H{sub 7}, C{sub 7}H{sub 7}). These compounds had been characterized by infrared spectroscopy, ultraviolet spectroscopy, {sup 1}H, {sup 13}C NMR spectroscopy and single crystal X-ray crystallography. The infrared spectra of these compounds showed three important peaks indicating the formation of dithiocarbamate compounds, ν(CN), ν(CS) and ν(Sn-S) band which present in the region of 1444–1519, 954–1098 and 318–349 cm{sup −1} respectively. The ultraviolet-visible spectra showed an absorption band for the π - π* transition of NCS group in the range of 253 – 259 nm due to the intramolecular charge transfer of the ligand. The {sup 13}C NMR spectra showed an important shift for δ(N{sup 13}CS{sub 2}) in the range of 196.8 – 201.9 ppm.. Single crystal X-ray diffraction studies showed three new structures with the general formula of PhSnCl[S{sub 2}CN(Et)(i−Pr)]{sub 2}, MeSnCl[S{sub 2}CN(Me)(Cy)]{sub 2} and MeSnCl[S{sub 2}CN(i−Pr)(CH{sub 2}Ph)]{sub 2}.

    Full Text Available O objetivo deste trabalho foi analisar fertilizantes tipo fritas comercializados no Brasil, utilizando o método prescrito para análise de fertilizantes minerais não-fritas, o que normalmente tem sido feito na rotina pelos laboratórios de análises de fertilizantes. Também foram analisados os teores de Cd, Ni e Pb nesses fertilizantes. Observou-se que o método utilizado foi adequado para a análise dos fertilizantes tipo fritas, o que indica que as fritas comercializadas no Brasil não são realmente fritas, isto é, silicatos fundidos com micronutrientes. A presença de micronutrientes metálicos nos produtos sem as respectivas garantias e a alta concentração de metais indesejáveis, principalmente Pb, são fortes indícios de utilização de resíduos industriais na fabricação desses fertilizantes. Sugere-se que sejam estudados e propostos extratores químicos para avaliar a eficiência agrícola desses produtos.

La globalización, el aumento de las importaciones y exportaciones, y los tratados de libre comercio han propiciado un mayor intercambio y acceso de los alimentos a nivel mundial; junto con ello los problemas asociados a los fraudes tales como la adulteración, sustitución, la intencionalidad, y falsificación se han incrementado. Por ello, se han reportado varios trabajos asociados al fraude alimentario, donde en la mayoría de ellas se muestran aplicaciones de nuevas técnicas de identificación. Sin embargo, una discusión acerca de los tipos de fraude y su impacto sobre la sociedad, el bioterrorismo y la religión, ha sido poco abordada. Esta revisión se enfoca básicamente en describir los tipos de fraude en alimentos más comunes. Así como, se mencionan las recientes técnicas disponibles para detectar una adulteración en carnes.

O objetivo do trabalho foi verificar o efeito de três tipos de corte em beterraba minimamente avaliando sua qualidade durante a conservação refrigerada. Os cortes utilizados foram: fatia, cubo e retalho. Após o processamento as beterrabas foram armazenadas a 5degreesC e as avaliações sendo realizadas durante dez dias a cada dois dias. Beterrabas em fatias apresentaram maior respiração e maiores perdas dos pigmentos betalaínas e de sólidos solúveis durante o armazenamento. Através de análise sensorial, verificou-se que a qualidade visual do produto foi mantida por até quatro dias, independente do tipo de corte. O fator que mais depreciou a qualidade de beterraba minimamente processada foi a perda de coloração das raízes (esbranquiçamento. Pode-se concluir que a beterraba minimamente processada em fatias ou cubo apresenta conservação de, no máximo 4 dias, a 5degreesC, enquanto minimamente processada em retalho apresenta 6 dias de conservação.

    To determine the prevalence of pressure sores, their risk factors, and the responsible microbial agents in an acute-care hospital and to evaluate their management. A prevalence survey was conducted from 5 July through 9 July 2004. Investigators completed a standardized questionnaire for each hospitalized patient, including demographic data (age, sex, previous hospitalizations, etc.) and Braden scale risk factors (sensory perception, humidity, activity, mobility, nutrition, and friction and shear). Two experts in skin care detected pressure sores by physical examination of the patients. Each pressure sore was swabbed and inoculated on selective media. Management was evaluated by reviewing the clinical charts of each patient with a pressure sore. The study included 535 adult patients (aged 59 +/- 19 years): 75 ulcer sores were observed in 37 patients (prevalence=6.9%). Stage I sores accounted for 24% of the total, stage II for 29%, stage III 31%, and stage IV 16%. The most frequent site was the heel (41%), followed by the sacrum (20%), elbow (11%), back (7%) and ischial tuberosities (7%). Sixty (80%) were acquired while hospitalized. Age-adjusted multivariate analyses found that the risk factors significantly associated with pressure sores were Braden scorepressure sores (OR=5.0 95% CI: 2.2-11.6, psores (24.5%), mostly stage III and IV, were colonized by multiple-drug-resistant bacteria (i.e., methicillin resistant Staphylococcus aureus, extended spectrum beta-lactamase Enterobacteriaceae). Seven (9.3%) of the 75 ulcers were diagnosed only during the survey, by the experts; of the 68 diagnosed before the survey, 57 (83.8%) had been under treatment. Treatment was considered inappropriate according to French guidelines in 31.6% of the cases. This prospective prevalence study resulted in better awareness of the patients at risk for pressure sores. It also made the recently created mobile geriatrics unit better known within the hospital.

    Topalović, R

    1998-01-01

    The primary object of this paper is to give a retrospective of hospital development in Europe and Yugoslavia for the past twenty-five centuries. The earliest records of hospitals called the "iatreia" date back to the V century B.C., ancient Greece. The sick in those hospitals were treated with drugs as well operated on. The Romans, during the reign of the emperor Augustus, built valetudinaries within military camps. The name "hospital" was introduced in the IV century A.D. and has been used ever since. The first hospital was founded in Cesarea, i.e. in the East Roman Empire in Asia Minor. The chronology of the hospital development in the Middle Ages is given in table 1--"Chronology of Hospital Development in the Middle Ages." St. Sava (Nemanjić) founded the first Serbian hospital in the Monastery of Hilandar about 1199 and in 1208/1209 a hospital in the Monastery of Studenica. In the hospital of the Monastery of St. Arhangel in Prizren, according to the regulations prescribed by tzar Dusan, only curable patients were to be treated. The first hospital in Vojvodina in Bac near Novi Sad dates back to 1234. More data about hospitals in former Yugoslavia are given in table 2--"The Oldest Hospitals in former Yugoslavia" and about the Frontier Hospitals in Vojvodina in table 3--"Frontier Hospitals for the Wounded and Sick in Vojvodina". The first medical high school was established in Salerno in the IX century and the first European University in Bologna in 1088, where the School of Medicine was founded in 1156. The University in Paris was founded in 1107 and in Oxford in 1145.

    The main aim of this article is to evaluate the hospital expenditure by user in an efficiency perspective and to evaluate the quality of the health system using process indicators and outcome indicators. In an efficiency perspective the concept of technical efficiency has been chosen, and a correction has been made, as well, in what concerns a case-mix index (CMI). The indicators have been calculated by user in what concerns the main hospital activities (the expenditure in inpatient care by treated patient, in day hospital by treated patient, in outpatient care by consultation, etc), and as well the auxiliary sections of clinic support and the hotel support services. All the indicators have been corrected according to the case-mix index, in 2004, and have been weighted according to the relevance of its expenditure in total expenditure. In a quality perspective two types of indicators have been considered: process indicators and outcome indicators. Process indicators, as the percentage of surgeries in ambulatory care, the percentage of caesareans in total deliveries and the rate of autopsy. The outcome indicator number of episodes of inpatient care due to surgery infection in total days of inpatient care The composite indicator of efficiency, weighted by the inverse of the case-mix index presents the lower values in Tondela, Seia, and Fafe, while the Hospital of the Litoral Alentejano is, in this group, the most inefficient. The Agueda Hospital presents the better Composite Efficiency Indicator, in Group II, followed by the Barcelos and S. João da Madeira Hospitals, while the Figueira da Foz Hospital presents the worst situation. In hospitals from Group III the Hospitals of Vale de Sousa, EPE, and the Vila Franca de Xira Hospital present the better Composite Efficiency Indicator followed by the Barreiro Hospital, EPE. In Group IV it is the Hospital of S. Sebastião, EPE, that presents the lowest Composite Efficiency Indicator, followed by the Cascais Hospital, SPA

Foram analisados 16.095 nascimento. Verificou-se aumento da incidência de cesareanas com o aumento do peso do recém-nascido, nas duas maternidades, mas na maternidade particular a incidência foi mais elevada em relação à maternidade assistencial. Chamou a atenção o fato da não associação entre o tipo de parto e o peso do recém-nascido nas mulheres que tiveram atendimento particular. A predominância do sexo feminino no grupo de peso de 2.500 g e menos foi estatisticamente significante e do mesmo modo a maior proporção do sexo masculino nos recém-nascidos com mais de 4.000 g.In order to assess the influence of birth weight on the type of birth two maternity hospitals whose patients were of different socio-economic levels were studied. 16,095 births were analysed. It was discovered that the incidence of cesarian sections increased with the increase in birth weight in both hospitals, but that in the private hospital the incidence was four times higher than in the hospital for the poor. No relation was found, in those women who received private treatment, between type of brith and birth weight. Among those babies who weighed 2500g or less at birth, there was found to be a significant predominance of girls and for those who weighed more than 4000g there was, equally, a larger proportion of boys.

    Analyses and forecasts underscore the important role of nuclear power in energy supply in the 21st century. Important aspects in this respect are the conservation of fossil resources, the protection of the world's climate, and the continuity of supply. Present 1st and 2nd generation nuclear power plants ensure an economical and technically mature electricity supply. Advanced systems offering, e.g., higher efficiency of fuel utilization, simplified systems technology, and advanced safety characteristics, can make available additional benefits in using nuclear power. Upon an initiative of the U.S. Department of Energy (DOE), ten countries combine their efforts in developing such reactor concepts in the Generation IV International Forum (GIF). Argentina, Brazil, Canada, France, Japan, South Africa, South Korea, Switzerland, the United Kingdom, and the United States pursue the common objective in GIF to identify suitable nuclear power systems and promote their development up to the envisaged readiness for construction in 2030. Besides technical and economic questions of nuclear power generation, also other aspects must be considered with a view to the future use of nuclear power. The particularly relevant issues, such as the management of radioactive waste, the intensification of research and development, and international cooperation, have been taken up by the Bush administration at an early point in time and have been, or will be, incorporated in practical solutions, as in the case of the Yucca Mountain repository project.

    Raju, M. S.

    2012-01-01

    LSPRAY-IV is a Lagrangian spray solver developed for application with parallel computing and unstructured grids. It is designed to be massively parallel and could easily be coupled with any existing gas-phase flow and/or Monte Carlo Probability Density Function (PDF) solvers. The solver accommodates the use of an unstructured mesh with mixed elements of either triangular, quadrilateral, and/or tetrahedral type for the gas flow grid representation. It is mainly designed to predict the flow, thermal and transport properties of a rapidly vaporizing spray. Some important research areas covered as a part of the code development are: (1) the extension of combined CFD/scalar-Monte- Carlo-PDF method to spray modeling, (2) the multi-component liquid spray modeling, and (3) the assessment of various atomization models used in spray calculations. The current version contains the extension to the modeling of superheated sprays. The manual provides the user with an understanding of various models involved in the spray formulation, its code structure and solution algorithm, and various other issues related to parallelization and its coupling with other solvers.

    Full Text Available Actualmente, hay más de 42 millones de infectados con el virus de la inmunodeficiencia humana tipo 1 (VIH-1, de los cuales, 3,2 millones son niños y, de éstos, el 90% con transmisión vertical de la infección. Se considera que en Colombia más de 200.000 personas se han infectado desde el inicio de la pandemia y los estudios muestran una tendencia constante al aumento en las cifras de seroprevalencia en mujeres embarazadas y, por ende, en el número de recién nacidos infectados. El VIH-1 es primordialmente linfotrópico, pero su tropismo por el sistema nervioso central (SNC es bien conocido, lo que genera múltiples alteraciones neurológicas, particularmente prominentes en niños, de las cuales la más prevalerte es la encefalopatía. Clásicamente, se reconocen dos tipos de encefalopatía en esta población: encefalopatía temprana y tardía, ambas con diferentes características clínicas e inmunológicas. La infección por el VIH-1 en el SNC está limitada a los macrófagos, la microglía y los astrocitos en menor escala. Las neuronas, células principalmente afectadas en los pacientes con sida, raras veces son infectadas, por lo que se postula que factores solubles, provenientes tanto del huésped como del virus, son los principales causantes del daño neuronal. Los hallazgos presentados en esta revisión sugieren la posibilidad de que el SNC, en etapas tempranas del desarrollo, sea especialmente susceptible a la infección por el VIH-1. Las cifras epidemiológicas sugieren que este tipo de alteraciones clínicas serán cada vez más frecuentes; de ahí, la importancia de conocer la neuropatogénesis de la infección por el VIH-1.

    Wu, Ziqi; Robson, Stephani; Hollis, Brooke

    2013-01-01

    In the last decade, many hospital designs have taken inspiration from hotels, spurred by factors such as increased patient and family expectations and regulatory or financial incentives. Increasingly, research evidence suggests the value of enhancing the physical environment to foster healing and drive consumer decisions and perceptions of service quality. Although interest is increasing in the broader applicability of numerous hospitality concepts to the healthcare field, the focus of this article is design innovations, and the services that such innovations support, from the hospitality industry. To identify physical hotel design elements and associated operational features that have been used in the healthcare arena, a series of interviews with hospital and hotel design experts were conducted. Current examples and suggestions for future hospitality elements were also sought from the experts, academic journals, and news articles. Hospitality elements applied in existing hospitals that are addressed in this article include hotel-like rooms and decor; actual hotels incorporated into medical centers; hotel-quality food, room service, and dining facilities for families; welcoming lobbies and common spaces; hospitality-oriented customer service training; enhanced service offerings, including concierges; spas or therapy centers; hotel-style signage and way-finding tools; and entertainment features. Selected elements that have potential for future incorporation include executive lounges and/or communal lobbies with complimentary wireless Internet and refreshments, centralized controls for patients, and flexible furniture. Although the findings from this study underscore the need for more hospitality-like environments in hospitals, the investment decisions made by healthcare executives must be balanced with cost-effectiveness and the assurance that clinical excellence remains the top priority.

    Centrum Vyzkumu Rez (CVR) is research and development Company situated in Czech Republic and member of the UJV group. One of its major fields is material research for Generation IV reactor concepts, especially supercritical water-cooled reactor (SCWR), very high temperature/gas-cooled fast reactor (VHTR/GFR) and lead-cooled fast reactor (LFR). The CVR is equipped by and is building unique experimental facilities which simulate the environment in the active zones of these reactor concepts and enable to pre-qualify and to select proper constructional materials for the most stressed components of the facility (cladding, vessel, piping). New infrastructure is founded within the Sustainable Energy project focused on implementation the Generation IV and fusion experimental facilities. The research of SCWR concept is divided to research and development of the constructional materials ensured by SuperCritical Water Loop (SCWL) and fuel components research on Fuel Qualification Test loop (SCWL-FQT). SCWL provides environment of the primary circuits of European SCWR, pressure 25 MPa, temperature 600 deg. C and its major purpose is to simulate behavior of the primary medium and candidate constructional materials. On-line monitoring system is included to collect the operational data relevant to experiment and its evaluation (pH, conductivity, chemical species concentration). SCWL-FQT is facility focused on the behavior of cladding material and fuel at the conditions of so-called preheater, the first pass of the medium through the fuel (in case of European SCWR concept). The conditions are 450 deg. C and 25 MPa. SCWL-FQT is unique facility enabling research of the shortened fuel rods. VHTR/GFR research covers material testing and also cleaning methods of the medium in primary circuit. The High Temperature Helium Loop (HTHL) enables exposure of materials and simulates the VHTR/GFR core environment to analyze the behavior of medium, especially in presence of organic compounds and

    This study evaluates whether emergency department septic shock patients without a fever (reported or measured) receive less IV fluids, have decreased antibiotic administration, and suffer increased in-hospital mortality. This was a secondary analysis of a prospective, observational study of patients with shock. The study was conducted in an urban, academic emergency department. The original study enrolled consecutive adult (aged 18 yr or older) emergency department patients from November 11, 2012, to September 23, 2013, who met one of the following shock criteria: 1) systolic blood pressure less than 90 mm Hg after at least 1L IV fluids, 2) new vasopressor requirement, or 3) systolic blood pressure less than 90 mm Hg and IV fluids held for concern of fluid overload. The current study is limited to patients with septic shock. Patients were grouped as febrile if they had a subjective fever or a measured temperature >100.4°F documented in the emergency department; afebrile patients lacked both. Among 378 patients with septic shock, 207 of 378 (55%; 50-60%) were febrile by history or measurement. Afebrile patients had lower rates of antibiotic administration in the emergency department (81% vs 94%; p < 0.01), lower mean volumes of IV fluids (2,607 vs 3,013 mL; p < 0.01), and higher in-hospital mortality rates (33% vs 11%; p < 0.01). After adjusting for bicarbonate less than 20 mEq/L, lactate concentration, respiratory rate greater than or equal to 24 breaths/min, emergency department antibiotics, and emergency department IV fluids volume, being afebrile remained a significant predictor of in-hospital mortality (odds ratio, 4.3; 95% CI, 2.2-8.2; area under the curve = 0.83). In emergency department patients with septic shock, afebrile patients received lower rates of emergency department antibiotic administration, lower mean IV fluids volume, and suffered higher in-hospital mortality.

    The aim of this thesis was to study the system U +4 /ClO 4 - /NCS - /HMPA/ - Solvent. This was done by means of various physical chemical methods. Spectrophotometric and conductometric evidence indicated that the following are the important species, which exist in acetone solution: (U(ClO 4 ) 3 .3acetone) + , (U(NCS) 3 .5acetone) + , (U 2 (NCS) 9 .6acetone) - , (U(NCS) 3 .2HMPA.3acetone) + , (U(NCS) 5 .2HMPA) - , (U(ClO 4 ) 3 .3HMPA) + , (U(NCS).5HMPA) +3 , (U(NCS) 2 .4HMPA) +2 and (U(NCS) 3 .3HMPA) + . The replacement of the large ClO 4 - ion by the much smaller NCS - anion results in a change in coordination of the U +4 , from six to eight. The formation of the species (U(NCS) 5 .2HMPA) - wasalso suggested by infrared studies and solubility determinations. The effect of a polar solvent on U(NCS) 4 .4HMPA was also studied, which indicated that, on solvation in methyl cyanide, U(NCS) 4 .4HMPA loses bound HMPA molecules. The ultimate goal of this project, i.e. the determination of the successive stability constants of the uranium(IV)thiocyanato complexes in acetone, was not reached, however, due to limitations of the computer program used. A qualitative treatment revealed that the stability of (U(NCS) 3 .5acetone) + , in acetone, is of the same order of magnitude as that of Co(NCS) 3 - ; similarly the species (U 2 (NCS) 9 .6acetone) - seems to be as stable as C0(NCS) 4 =. It was also indicated that excess U +4 cannot remove all bound NCS - from Co +2 . Finally the thiocyanato complexes of U +4 , relative to those of CO +2 , seem to be more stable in methyl cyanide, a N-donor solvent, than in acetone, an O-donor solvent

  19. Common molecular determinants of tarantula huwentoxin-IV inhibition of Na+ channel voltage sensors in domains II and IV.

    The voltage sensors of domains II and IV of sodium channels are important determinants of activation and inactivation, respectively. Animal toxins that alter electrophysiological excitability of muscles and neurons often modify sodium channel activation by selectively interacting with domain II and inactivation by selectively interacting with domain IV. This suggests that there may be substantial differences between the toxin-binding sites in these two important domains. Here we explore the ability of the tarantula huwentoxin-IV (HWTX-IV) to inhibit the activity of the domain II and IV voltage sensors. HWTX-IV is specific for domain II, and we identify five residues in the S1-S2 (Glu-753) and S3-S4 (Glu-811, Leu-814, Asp-816, and Glu-818) regions of domain II that are crucial for inhibition of activation by HWTX-IV. These data indicate that a single residue in the S3-S4 linker (Glu-818 in hNav1.7) is crucial for allowing HWTX-IV to interact with the other key residues and trap the voltage sensor in the closed configuration. Mutagenesis analysis indicates that the five corresponding residues in domain IV are all critical for endowing HWTX-IV with the ability to inhibit fast inactivation. Our data suggest that the toxin-binding motif in domain II is conserved in domain IV. Increasing our understanding of the molecular determinants of toxin interactions with voltage-gated sodium channels may permit development of enhanced isoform-specific voltage-gating modifiers.

  20. An Integrated Safety Assessment Methodology for Generation IV Nuclear Systems

    Leahy, Timothy J.

    2010-01-01

    The Generation IV International Forum (GIF) Risk and Safety Working Group (RSWG) was created to develop an effective approach for the safety of Generation IV advanced nuclear energy systems. Early work of the RSWG focused on defining a safety philosophy founded on lessons learned from current and prior generations of nuclear technologies, and on identifying technology characteristics that may help achieve Generation IV safety goals. More recent RSWG work has focused on the definition of an integrated safety assessment methodology for evaluating the safety of Generation IV systems. The methodology, tentatively called ISAM, is an integrated 'toolkit' consisting of analytical techniques that are available and matched to appropriate stages of Generation IV system concept development. The integrated methodology is intended to yield safety-related insights that help actively drive the evolving design throughout the technology development cycle, potentially resulting in enhanced safety, reduced costs, and shortened development time.

    1983-01-01

    The use of uranous nitrate, U(IV), as a plutonium reductant in the Purex solvent extraction process could significantly reduce the waste generation at the Savannah River Plant. The current reductant is a ferrous sulfamate (FS)/hydroxylamine nitrate (HAN) mixture. The iron and sulfate in the FS are major contributors to waste generation. The U(IV) reductant oxidizes to U(VI) producing no waste. The Savannah River Laboratory has developed an efficient electrochemical cell for U(IV) production and has demonstrated the effectiveness of U(IV) as a plutonium reductant. Plant tests and economic analyses are currently being conducted to determine the cost effectiveness of U(IV) implementation. The results of recent studies are presented

    As assessed by molecular sieve chromatography and quantitation by a specific radioimmunoassay, apoA-IV is associated in plasma with the triglyceride-rich lipoproteins, to a high density lipoprotein (HDL) subfraction of smaller size than HDL3, and to the plasma lipoprotein-free fraction (LFF). In this study, the turnover of apoA-IV associated to the triglyceride-rich lipoproteins, HDL and LFF was investigated in vivo in normal volunteers. Human apoA-IV isolated from the thoracic duct lymph chylomicrons was radioiodinated and incubated with plasma withdrawn from normal volunteers after a fatty meal. Radioiodinated apoA-IV-labeled triglyceride-rich lipoproteins, HDL, and LFF were then isolated by chromatography on an AcA 34 column. Shortly after the injection of the radioiodinated apoA-IV-labeled triglyceride-rich lipoproteins, most of the radioactivity could be recovered in the HDL and LFF column fractions. On the other hand, when radioiodinated apoA-IV-labeled HDL or LFF were injected, the radioactivity remained with the originally injected fractions at all times. The residence time in plasma of 125 I-labeled apoA-IV, when injected in association with HDL or LFF, was 1.61 and 0.55 days, respectively. When 125 I-labeled apoA-IV was injected as a free protein, the radioactivity distributed rapidly among the three plasma pools in proportion to their mass. The overall fractional catabolic rate of apoA-IV in plasma was measured in the three normal subjects and averaged 1.56 pools per day. The mean degradation rate of apoA-IV was 8.69 mg/kg X day

  4. The role of erythropoiesis stimulating agents and intravenous (IV) iron in the cardio renal anemia syndrome.

    Silverberg, Donald S

    2011-11-01

    Anemia is common in Congestive Heart Failure (CHF) and is associated with an increased mortality, morbidity and progressive renal failure. The most common causes of the anemia in CHF are (1) the associated Chronic Kidney Disease (CKD), which causes depression of erythropoietin (EPO) production in the kidney, and (2) excessive cytokine production in CHF, which can cause both depression of erythropoietin production in the kidney and depression of erythropoietin response in the bone marrow. The cytokines can also induce iron deficiency by increasing hepcidin production from the liver, which both reduces gastrointestinal iron absorption and reduces iron release from iron stores located in the macrophages and hepatocytes. It appears that iron deficiency is very common in CHF and is rarely recognized or treated. The iron deficiency can cause a thrombocytosis that might contribute to cardiovascular complications in both CHF and CKD and is reversible with iron treatment. Thus, attempts to control this anemia in CHF will have to take into consideration both the use of both Erythropoiesis Stimulating Agents (ESA) such as EPO and oral and, probably more importantly, intravenous (IV) iron. Many studies of anemia in CHF with ESA and oral or IV iron and even with IV iron without ESA have shown a positive effect on hospitalization, New York Heart Association functional class, cardiac and renal function, quality of life, exercise capacity and reduced Beta Natriuretic Peptide and have not demonstrated an increase in cardiovascular damage related to the therapy. However, adequately powered long-term placebo-controlled studies of ESA and of IV iron in CHF are still needed and are currently being carried out.

Realizaram-se amostragens no dia do enchimento das bolsas, aos 30; 90 e 180 dias de armazenamento. Analisaram-se o teor de água, a condutividade elétrica, o percentual de germinação, a massa específica aparente da soja, além do teor de ácidos graxos livres e o índice de peróxido do óleo bruto extraído dela. Os teores de água da soja armazenada úmida e seca mantiveram-se próximos dos valores obtidos no início do período de armazenamento. Observou-se tendência de elevação da condutividade elétrica e decréscimo do percentual de germinação somente na soja úmida, principalmente após 90 dias de armazenamento. Não foi verificado decréscimo da massa específica aparente do material armazenado úmido e seco. Com relação aos parâmetros qualitativos do óleo bruto, observou-se que os valores obtidos se mantiveram abaixo do limite máximo exigido pela legislação para a comercialização de óleo bruto de soja.

Neste tipo de evaporímetro a medida da evaporação é feita por processo volumétrieo, dispensando o emprego de mecanismos de precisão e dispendiosos. Foi feita uma análise matemática do princípio de funcionamento do novo evaporímetro, demonstrando-se oferecer exatidão plenamente satisfatória para propósitos práticos. São dados suficientes detalhes construtivos, de instalação e operação, a fim de permitir que pessoas e entidades interessadas possam reproduzi-lo e comprovar as vantagens de seu emprêgo.In this paper is described a new type of evaporimeter, the principle of operation of which is based on physical laws governing the surface tension phenomenon. The measurement of evaporation in, the new evaporimeter, described as Evaporimeter IA-58, is made by simple volumetric procedure, thus avoiding the use of precise and expensive mechanisms. A mathematical analysis of the principle of operation is made, and proves that the new evaporimeter can offer satisfactory xeaults for practical use. The operation of the new evaporimeter is very simple, since only volumetric measurements are made, with a graduated cylinder of 1000 ml, both of the added water to restore the water level to the same initial level and the outflown or excess water. It is believed that enough details are given to allow the understanding of the construction, installation and operation of the new evaporimeter, bo that interested persons or organizations could have the model reproduced and verify the advantage of its use.

La escuela fue construida antes de la creación de la Norma Venezolana Sismorresistente Covenin 1756. Los resultados del análisis estructural demostraron insuficiente capacidad de respuesta ante las solicitaciones de servicio, alta vulnerabilidad ante la acción sísmica y deficiencias en la cantidad y distribución del acero de refuerzo. Por tal motivo se planteó el reforzamiento de la superestructura mediante la construcción de muros tipo panel, verificando su acción sobre el sistema de pilotaje existente. Para el modelaje se emplearon los valores de resistencia del concreto obtenidos en los ensayos destructivos realizados por el laboratorio de materiales del Decanato de Ingeniería Civil de la Universidad Centroccidental Lisandro Alvarado, y los parámetros del suelo provenientes del estudio geotécnico. This article presents the study of structural reinforcement for a building of educational use, known as "Old Type II". The school was built before the creation of the Venezuelan Seismoresistant Covenin 1756. The results of the structural analysis showed insufficient responsiveness to service requests, high vulnerability to seismic action and deficiencies in the quantity and distribution of reinforcing steel. For this reason, the reinforcement of the superstructure was proposed by the construction of panel walls, verifying their action on the existing piloting system. For the modeling, the values of resistance of the concrete obtained in the destructive tests made by the materials laboratory of the School of Civil Engineering of the Universidad Centroccidental Lisandro Alvarado and the soil parameters from the geotechnical study were used.

    2013-09-01

    Full Text Available El tratamiento de la diabetes tipo 2 en el anciano representa un importante reto tanto desde el punto de vista clínico como del de la salud pública. El envejecimiento poblacional está condicionando un marcado incremento de la pandemia de diabetes en las personas de edad avanzada. Sin embargo, existen pocas evidencias científicas que apoyen el tratamiento más adecuado de la diabetes en los ancianos. Dada la gran heterogeneidad de la población anciana, que incluye a sujetos con muy diferente capacidad funcional y cognitiva, diversa comorbilidad y con muy diferente expectativa de vida, resulta crucial realizar una valoración global del anciano desde una perspectiva biopsicosocial y abordar integralmente los factores de riesgo vascular, planteando unos objetivos personalizados de control glucémico. En ancianos frágiles o con corta expectativa de vida puede ser razonable mantener un objetivo de HbA1c de 7,6-8,5%. La estrategia terapéutica en el anciano con diabetes tipo 2 debe individualizarse y consensuarse con el paciente y sus cuidadores, en función del objetivo planteado. Mejorar la calidad de vida, preservar la seguridad del paciente y evitar los efectos adversos del tratamiento antidiabético deben ser objetivos básicos. Dada la mayor predisposición de los ancianos a las hipoglucemias y sus graves consecuencias en esta población, deberían priorizarse las terapias antidiabéticas que minimicen el riesgo de episodios hipoglucémicos.

In general terms, the higher cost of living in Buenos Aires than in the interior of the country. Due to the high integration of national regional markets, tradable goods do not present major price discrepancies, which are observed in nontradables. The terms of trade and productivity differences between regions, through their impact on relative wages, stand out as the main determinant of the Real Exchange Rate. To a lesser extent, asymmetries in public policies and differences in population densities also have an impact on the regional price structure.JEL Classification: R10Keywords: Real Exchange Rate, Regional Markets, Cordoba, Buenos Aires.

    2004-07-01

    Full Text Available El propósito de este estudio fue el de explorar las condiciones vulnerabilidad sociodemográfica en Costa Rica, a partir del análisis de los cambios en los tipos de hogar y el ciclo de vida de las familias en condiciones de pobreza, utilizando información de las Encuestas de Hogares de 1987, 1994 y 2002. Los principales hallazgos revelan modificaciones importantes en la estructura y composición de los hogares y familias en el periodo de estudio, asociado a cambios en la dinámica sociodemográfica de la sociedad costarricense. La evolución en la incidencia de la pobreza por tipo de hogar muestra que ésta es mayor entre los hogares nucleares que cuentan con hijos y al convertirse en monoparentales. La incidencia es más alta en 1987, se reduce para 1994 y prácticamente se mantiene para el 2002. No obstante que en todas las fases del ciclo de vida familiar la incidencia de la pobreza disminuyó en el periodo 1987-1994, en el periodo más reciente al 2002 la incidencia es mayor en las etapas en que las familias poseen más hijos dependientes menores de 18 años, lo que expone a estas familias a una mayor vulnerabilidad a situaciones de pobreza. Los hogares y familias con mayor riesgo de vulnerabilidad ante la pobreza, se hallaron entre aquellos con mayor cantidad de miembros dependientes menores de edad y jefeados por mujeres. No se encontraron evidencias significativas para afirmar que el estancamiento observado en los niveles de pobreza en el país hasta el 2002, fuese producto de los cambios encontrados en los patrones familiares, aunque ciertamente se hace necesario profundizar el análisis de las interrelaciones entre pobreza y cambios demográficos.

  11. IUE observations of interstellar Si IV and C IV lines observed in the spectra of Wolf-Rayet stars

    International Nuclear Information System (INIS)

    1980-01-01

    Recent IUE observations of Wolf-Rayet stars show narrow absorption lines in the highly ionized species of Si IV and C IV. The strengths of these 'interstellar' Si IV and C IV lines observed in the spectra of 10 WR stars and two other early-type stars are compared. Of the WR sample, six stars exhibit very strong Si IV and C IV lines (Wsub(lambda) approximately 0.3 to 0.5 A) whilst the other four stars show much weaker lines (Wsub(lambda) approximately 0.1 A). There is no correlation between the strengths of these lines with either stellar distance or colour excess. The weaker absorptions may arise in the individual stellar H II regions, the observed strengths being consistent with those expected for stars with Tsub(eff) = 30 000 K. Five of the other stars which exhibit very strong absorptions lie in the line of sight to active interstellar regions (Cygnus and Carina nebulae) and it is considered probable that, in addition to their H II region components, the bulk of the strong Si IV and C IV absorptions originate in hot gas associated with these active regions. In the case of the WN5 star HD 50896 violet-displaced components are observed in the interstellar lines of low ionization species. These are thought to be produced in the ring nebula S308 surrounding HD 50896. (author)

    In recent years a large number of complexes of amine N-oxides with a wide variety of metal salts have been isolated and characterized. Less attention has been paid to the aromatic amine N-oxides complexes with Th(IV) thiocyanate. In the present communication studies are reported on Th(IV) thiocyanate complexes of pyridine N-oxide (PyO), quinoline N-oxide (QO), isoquinoline N-oxide (IsqO), 2-picoline N-oxide (2-picO), 3-picoline N-oxide (3-picO) and 4-picoline N-oxide (4-picO) and comparisons are made with the existing complexes of 2,6-lutidine N-oxide (LNO), 2, 2'bipyridine N-N'-dioxide (BipyO 2 ), mono N-oxides of 2,2'-bipyridine (BipyNO) and 1,10-phenanthroline (PhenNO) and 1, 10-phenanthroline N-N'-dioxide (PhenO 2 ). The analytical data correspond to the composition Th(NCS) 4 .4L. The molar conductance of all the complexes in nitrobenzene in the range 2.5 to 4.5 Ω -1 cm 2 mol -1 indicate them to be non-electrolytes. The results of IR spectroscopy and thermogravimetry are given and discussed. (author)

    2018-04-10

    A series of new U(IV) and Th(IV) fluorides, Na 7 U 6 F 31 (1), NaUF 5 (2), NaU 2 F 9 (3), KTh 2 F 9 (4), NaTh 2 F 9 (5), (H 3 O)Th 3 F 13 (6), and (H 3 O)U 3 F 13 (7), was obtained using hydrothermal and low-temperature flux methods. Mild hydrothermal reactions with uranyl acetate as a precursor yielded 1, 7, and the monoclinic polymorph of NaU 2 F 9 , whereas direct reactions between UF 4 and NaF led to the formation of 2 and orthorhombic NaU 2 F 9 (3). This highlights an unexpected difference in reaction products when different starting uranium sources are used. All seven compounds were characterized by single-crystal X-ray diffraction, and their structures are compared on the basis of cation topology, revealing a close topological resemblance between fluorides on the basis of the layers observed in NaUF 5 (H 2 O). Phase-pure samples of 1, 2, and both polymorphs of NaU 2 F 9 were obtained, and their spectroscopic and magnetic properties were measured. The UV-vis data are dominated by the presence of U 4+ cations and agree well with the electronic transitions. Effective magnetic moments of the studied compounds were found to range from 3.08 to 3.59 μ B .

  5. Generation IV nuclear reactors: Current status and future prospects

    Generation IV nuclear power plants (GEN IV NPPs) are supposed to become, in many countries, an important source of base load power in the middle–long term (2030–2050). Nowadays there are many designs of these NPPs but for political, strategic and economic reasons only few of them will be deployed. International literature proposes many papers and reports dealing with GEN IV NPPs, but there is an evident difference in the types and structures of the information and a general unbiased overview is missing. This paper fills the gap, presenting the state-of-the-art for GEN IV NPPs technologies (VHTR, SFR, SCWR, GFR, LFR and MSR) providing a comprehensive literature review of the different designs, discussing the major R and D challenges and comparing them with other advanced technologies available for the middle- and long-term energy market. The result of this research shows that the possible applications for GEN IV technologies are wider than current NPPs. The economics of some GEN IV NPPs is similar to actual NPPs but the “carbon cost” for fossil-fired power plants would increase the relative valuation. However, GEN IV NPPs still require substantial R and D effort, preventing short-term commercial adoption. - Highlights: • Generation IV reactors are the middle–long term technology for nuclear energy. • This paper provides an overview and a taxonomy for the designs under consideration. • R and D efforts are in the material, heat exchangers, power conversion unit and fuel. • The life cycle costs are competitive with other innovative technologies. • The hydrogen economy will foster the development of Generation IV reactors

  6. Dissimilatory Fe(III) and Mn(IV) reduction.

    1991-06-01

    The oxidation of organic matter coupled to the reduction of Fe(III) or Mn(IV) is one of the most important biogeochemical reactions in aquatic sediments, soils, and groundwater. This process, which may have been the first globally significant mechanism for the oxidation of organic matter to carbon dioxide, plays an important role in the oxidation of natural and contaminant organic compounds in a variety of environments and contributes to other phenomena of widespread significance such as the release of metals and nutrients into water supplies, the magnetization of sediments, and the corrosion of metal. Until recently, much of the Fe(III) and Mn(IV) reduction in sedimentary environments was considered to be the result of nonenzymatic processes. However, microorganisms which can effectively couple the oxidation of organic compounds to the reduction of Fe(III) or Mn(IV) have recently been discovered. With Fe(III) or Mn(IV) as the sole electron acceptor, these organisms can completely oxidize fatty acids, hydrogen, or a variety of monoaromatic compounds. This metabolism provides energy to support growth. Sugars and amino acids can be completely oxidized by the cooperative activity of fermentative microorganisms and hydrogen- and fatty-acid-oxidizing Fe(III) and Mn(IV) reducers. This provides a microbial mechanism for the oxidation of the complex assemblage of sedimentary organic matter in Fe(III)- or Mn(IV)-reducing environments. The available evidence indicates that this enzymatic reduction of Fe(III) or Mn(IV) accounts for most of the oxidation of organic matter coupled to reduction of Fe(III) and Mn(IV) in sedimentary environments. Little is known about the diversity and ecology of the microorganisms responsible for Fe(III) and Mn(IV) reduction, and only preliminary studies have been conducted on the physiology and biochemistry of this process.

  11. Hospital turnaround strategies.

    Langabeer, James

    2008-01-01

    Despite reports of higher profitability in recent years, hospitals are failing at a faster rate than ever before. Although many hospitals leave decisions regarding revenues and costs to chief financial officers and their staff, this is a recipe for disaster. From research conducted over the last 4 years on hospital bankruptcies and turnarounds, the author found that a common series of actions will help organizations evade collapse. The author explored these turnaround strategies through research and analysis of a variety of hospitals and health systems that had a high probability of immediate financial crisis or collapse. His continued observation and analysis of these hospitals in subsequent years showed that most hospitals never emerge from their bleak financial conditions. However, a few hospital administrations have successfully turned around their organizations.

    Full Text Available Modern studies emphasized on the needs of researching the hospitality as relevant aspects of tourism and hospitality fields. Anyway, these approaches are inextricably intertwined to the industry of tourism and do not take seriously the anthropological and sociological roots of hospitality. In fact, the hotel seems to be a partial sphere of hospitality at all. Under this context, the present paper explores the issue of hospitality enrooted in the political and economic indo-European principle of free-transit which is associated to a much broader origin.  Starting from the premise etymologically hostel and hospital share similar origins, we follow the contributions of J Derrida to determine the elements that formed the hospitality up to date.

    The crystal structure of ammonium octacyanomolybdate(IV) and rubidium octacyanomolybdate(IV) has been determined by the single-crystal method on a Syntex P2/sub 1/ automatic diffractometer: ((NH/sub 4/)/sub 4/ Mo(CN)/sub 4/) 0.5H/sub 2/O (I) (space group Pma2, a = 15.550(3), b = 14.118(3), c = 7.438(1) A, Z = 4, R = 0.062) and Rb/sub 4/(Mo(CN)/sub 8/). 3H/sub 2/O (II) (space group P4/sub 1/2/sub 1/2, a = 9.300(10, c = 21.807(3) A, Z = 4, R = 0.065). The Mo atoms in structure I occupy two special positions (2(b) and 2(c)) and are each surrounded by eight CN ligands. The mean value of the Mo-C distances for Mo(1) is equal to 2.216 A, and the corresponding value for Mo(2) is 2.235 A. The mean Mo-N lengths are practically identical in both molybdenum anions and are equal to 3.353 A. The mean values of the C identical with N bond lengths in the Mo(1) and Mo(2) anions are 1.118 and 1.137 A, respectively. The MoCn angles vary from 175.0 to 178.4/sup 0/. The coordination sphere of the Mo(1) atom corresponds to a dodecahedron with a single twofold symmetry axis, and the coordination polyhedron of the Mo(2) atom in an antiprism of m symmetry. In structure II the Mo-C distances are within the 2.130-2.160-A range, and the Mo-N distances range from 3.290 to 3.307 A. The MoCN angles vary from 176.0 to 179.3/sup 0/, and the coordination polyhedron of (MoC/sub 8/) is a dodecahedron of 2 symmetry.

    Full Text Available RESUMO Este trabalho teve como objetivo avaliar chapas de partículas do tipo aglomerado convencional, chapas tipo Medium Density Particleboard (MDP e as do tipo aglomerado com inclusão laminar. As chapas avaliadas foram fabricadas com partículas de Acacia mangium e no aglomerado com inclusão laminar utilizaram-se lâminas de Schizolobium amazonicum. O aglomerado convencional e o aglomerado com inclusão laminar apresentaram umidade de equilíbrio higroscópico estatisticamente superior ao MDP. O aglomerado com inclusão laminar apresentou maior índice de inchamento em espessura após duas horas de imersão em água, valores de módulo de ruptura em flexão estática maiores e maior resistência ao arrancamento de parafuso. As chapas do tipo MDP apresentaram maior resistência à tração perpendicular. Não foram observadas diferenças significativas nas demais propriedades. Conclui-se que a inclusão laminar melhorou o módulo de ruptura e o arrancamento de parafuso, enquanto a utilização de partículas finas nas faces melhorou as propriedades físicas das chapas.

    Full Text Available OBJETIVO: Conhecer os pensamentos, sentimentos e comportamentos em relação à dieta de mulheres portadoras de diabetes tipo 2. MÉTODOS: Trata-se de um estudo descritivo exploratório, de natureza qualitativa. Foram entrevistadas oito mulheres portadoras de diabetes tipo 2 em uma Unidade Básica de Saúde do município de Ribeirão Preto, SP, em janeiro de 2003. Foi utilizada entrevista semi-estruturada para a coleta dos dados. O referencial teórico adotado foi a teoria das representações sociais. Os registros audiogravados e transcritos foram submetidos à análise temática de conteúdo. RESULTADOS: Os resultados evidenciaram dificuldade no seguimento da dieta prescrita, em função dos diversos significados associados, tais como a perda do prazer de comer e beber, da autonomia e da liberdade para se alimentar. Assim, seguir a dieta adquire caráter extremamente aversivo e cerceador, tendo representação de que realizá-la traz prejuízos à saúde. A freqüente ausência de sintomas foi citada como um dos aspectos que dificultam o seguimento da dieta. Outra dificuldade foi tocar, olhar e manipular os alimentos durante o seu preparo e não poder ingeri-los. Os alimentos doces despontaram como algo extremamente desejado. Transgressão e desejo alimentar estão igualmente presentes na vida das pessoas entrevistadas. Seguir o padrão dietético recomendado elicia tristeza, e o ato de comer, muitas vezes, vem acompanhado de medo, culpa e revolta. CONCLUSÕES: O comportamento alimentar da mulher portadora de diabetes tipo 2 é bastante complexo e precisa ser compreendido à luz dos aspectos psicológicos, biológicos, sociais, culturais, psicológicos e econômicos para maior eficácia das intervenções educativas.OBJECTIVE: To explore type 2 diabetes women's thoughts, feelings and behaviors concerning diet.

    ABSTRACTStudies indicate that DSM-5 criteria for delirium are relatively restrictive, and identify different cases of delirium compared with previous systems. We evaluate four outcomes of delirium (mortality, length of hospital stay, institutionalization, and cognitive improvement) in relation to delirium defined by different DSM classification systems.Prospective, longitudinal study of patients aged 70+ admitted to medical wards of a general hospital. Participants were assessed up to a maximum of four times during two weeks, using DSM-5 and DSM-IV criteria, DRS-R98 and CAM scales as proxies for DSM III-R and DSM III.Of the 200 assessed patients (mean age 81.1, SD = 6.5; and 50% female) during hospitalization, delirium was identified in 41 (20.5%) using DSM-5, 45 (22.5%) according to DSM-IV, 46 (23%) with CAM positive, and 37 (18.5%) with DRS-R98 severity score >15. Mortality was significantly associated with delirium according to any classification system, but those identified with DSM-5 were at greater risk. Length of stay was significantly longer for those with DSM-IV delirium. Discharge to a care home was associated only with DRS-R98 defined delirium. Cognitive improvement was only associated with CAM and DSM-IV. Different classification systems for delirium identify populations with different outcomes.

    We combined absorption and fluorescence spectroscopy to study the speciation of U(IV) in solution in concentrations down to 10{sup -6} M uranium. With our time-resolved laser-induced fluorescence setup we could determine the fluorescence decay time of U(IV) in perchloric as well as in chloric acid with 2.6 ± 0.3 ns at room temperature and 148.4 ± 6.5 ns at liquid nitrogen temperature. For the U(IV) sulfate system, we observed a bathochromic shift and a peak shape modification in the fluorescence spectra with increasing sulfate concentration in solution. Thus, the potential of U(IV) fluorescence for speciation analysis could be proven.

    The complexation of plutonium(IV) with sulfate at variable temperatures has been investigated by solvent extraction method. A NaBrO 3 solution was used as holding oxidant to maintain the plutonium(IV) oxidation state throughout the experiments. The distribution ratio of Pu(IV) between the organic and aqueous phases was found to decrease as the concentrations of sulfate were increased. Stability constants of the 1:1 and 1:2 Pu(IV)-HSO 4 - complexes, dominant in the aqueous phase, were calculated from the effect of [HSO 4 - ] on the distribution ratio. The enthalpy and entropy of complexation were calculated from the stability constants at different temperatures using the Van't Hoff equation

    We report a 7 year-old girl with mapuche ancestors, diagnosed as a cerebral palsy since infancy and on active rehabilitation. She acquired motor and cognitive skills at 3 years of age. At 5 years of age, a slow neurological deterioration started, associated to visual impairment. Optic atrophy was added to the typical neurological exam of ataxic cerebral palsy and the diagnosis was re-considered. Neuroimaging showed a slow and progressive atrophy of intracerebral structures and ultramicroscopy revealed intracytoplasmatic inclusions in conjunctiva and skin, compatible with mucolipidoses type IV (ML-IV). ML-IV must be included in the differential diagnosis of cerebral palsy associated with loss of acquired skills and progressive visual impairment. Electron microscopy of skin or conjunctiva is a useful diagnostic test. Suspicion of ML-IV must not be restricted to Ashkenazi Jewish population.

    Commercial closed-suctions drainage systems are commonly used in the United States and many other countries for use in neurosurgical cases. However, in Tanzania and other developing nations with fewer resources, these are not available. This report explores another option for a closed-system drainage system utilizing inexpensive supplies found commonly in hospitals around the world. Sterile IV-tubing is cut, inserted into the wound, and brought out through an adjacent puncture incision. For suction, an empty plastic bottle can be attached to the tubing. The IV-tubing closed-suction drainage system was applied in both cranial and spinal neurosurgical procedures, including as subdural, subgaleal, epidural, and suprafacial drains. It maintained suction and was an adequate substitute when commercial drains are unavailable. This report illustrates how sterile IV-tubing can be adapted for use as a closed-drainage system. It utilizes inexpensive supplies commonly found in many hospitals throughout the world and can be applied to both cranial and spinal neurosurgical procedures.

    Full Text Available Type 2 diabetes mellitus the most frequent metabolic disease, is induced by factors so far largely unknown. Genetic and environmental causes are implicated, among the latter obesity and sedentary life are the most important. The discovery of new hormones controlling food intake such as leptin, ghrelin and the YY3-36 peptide, are expected to provide new tools to reduce overfeeding. The genes associated with type 2 diabetes are intensively sought without success.It is possible that the genetic transmission is more complex than suppossed. The theory of the thrifty gene proposes an explanation for the increased obesity and diabetes in ethnic groups in transition from preindustrial to industrialized cultures. The theory of the fetal origins of adult disease, proposes that in the fetal life there is a window for metabolic programming under stress or caloric restriction. If the subject, however, at the adult life consumes excessive caloric intake, has a high risk for the metabolic syndrome. The mechanisms involved in insulin resistance are complex, and several molecules are under study as candidates to explain it. The diminution in insulin secretion is an other important factor for the initiation of type 2 diabetes. Glucotoxicity and lipotoxicity are factors that further reduce insulin secretion. Recent evidence indicates that inflammation is implicated in the onset of both diabetes and atherosclerosis. The elucidation of the nature of this process, as well as the pathways involved will be another important tool for a better management of this disease.La causa de la diabetes mellitus tipo 2, la enfermedad metabólica más frecuente, no es bien conocida. Tiene un componente genético y otro ambiental, en éste destacan la obesidad y el sedentarismo.

    Full Text Available Primary central nervous system atypical teratoid/rhabdoid tumors mostly occur during early childhood and are almost invariably fatal. These tumors show similar histological and radiological features to primitive neuroectodermal tumor, meduloblastoma and choroid plexus carcinoma, but present different biological behaviors. We present the case of an 18 year-old man who presented headache, vomiting and ataxia. CT-scan and MRI revealed a posterior fossa tumor. A gross total resection was performed. An intraoperative study showed papillary-like tumors with large cells and mitotic features. Histological examination showed two different main growth patterns: solid sheets of undifferentiated polygonal cells with papillary features and rhabdoid cells. Immunohistochemically, these rhabdoid cells were positive for vimentin, epithelial membrane antigen, smooth-muscle actin, cytokeratin, S-100 protein, and glial fibrillary acidic protein. Electro-microscopically, the typical rhabdoid cells contained whorled bundles of intermediate filaments in their cytoplasm. A rhabdoid tumor is a clinicalpathological entity and emphasizes the necessity to distinguish this unique tumor from other pediatric central nervous system neoplasms. Cytopathological features, immunohistochemistry and electro-microscopy differential diagnoses are discussed.Los tumores de tipo rabdoide primarios en cualquier sitio son raros y en el sistema nervioso central son extremadamente raros y ocurren principalmente en niños, el tumor teratoide/rabdoide es el tumor más frecuente dentro de este grupo y de evolución clínica fatal. El tumor neuroectodermico primitivo, medulobalstoma y al carcinoma de plexos coroides son tumores generalmente muestran aspectos clínicos radiológicos e histológicos similares, con evolución diferente. Presentamos el caso de un hombre joven de 18 años que inició con cefalea vómitos y ataxia. La imagen de TC muestra tumor en fosa posterior. Se realizó resecci
