Because latanoprost and the original formulation of travoprost that included benzalkonium chloride (BAK) have been shown to be similar with regard to tolerability, we compared initial topical intraocular pressure (IOP)-lowering medication change rates in patients newly treated with latanoprost or travoprost-Z monotherapy. At 14 clinical practice sites, medical records were abstracted for patients with a diagnosis of open-angle glaucoma or ocular hypertension and who were ≥40 years of age, had a baseline and at least one follow-up visit, and had no prior history of ocular prostaglandin use. Data regarding demographics, ocular/systemic medical histories, clinical variables, therapy initiations and reasons for changes, adverse events, and resource utilization were recorded from randomly chosen eligible charts. Primary outcomes were rates of and reasons for changing from the initial therapy within six months and across the full study period (1000 days). Data from 900 medical charts (latanoprost, 632; travoprost-Z, 268) were included. For both cohorts, average follow-up was >1 year. Cohorts were similar with regard to age (median ~67 years), gender distribution (>50% female), and diagnosis (~80% with open-angle glaucoma). Within six months, rates of index therapy change for latanoprost versus travoprost-Z were 21.2% (134/632) and 28.7% (77/268), respectively (p = 0.0148); across the full study period, rates were 34.5% (218/632) and 45.2% (121/268), respectively (p = 0.0026). Among those who changed their index therapy, insufficient IOP control was the most commonly reported reason followed by adverse events; hyperemia was the most commonly reported adverse event at index therapy change. In this "real world" study of changes in therapy in patients prescribed initial monotherapy with latanoprost with BAK or travoprost-Z with SofZia, medication changes were common in both treatment groups but statistically significantly more frequent with travoprost-Z.

We propose a new method to numerically compute the Z2 indices for disordered topological insulators in Kitaev's periodic table. All of the Z2 indices are derived from the index formulae which are expressed in terms of a pair of projections introduced by Avron, Seiler, and Simon. For a given pair of projections, the corresponding index is determined by the spectrum of the difference between the two projections. This difference exhibits remarkable and useful properties, as it is compact and has a supersymmetric structure in the spectrum. These properties enable highly efficient numerical calculation of the indices of disordered topological insulators. The method, which we propose, is demonstrated for the Bernevig-Hughes-Zhang and Wilson-Dirac models whose topological phases are characterized by a Z2 index in two and three dimensions, respectively.

In the last couple of year's computer based home control systems are getting more and more common in modern homes. For instance these systems take care of light control, heat control and security systems.  The latest trend is to use wireless communication like Z-Wave and ZigBee to interconnect...... different components in these systems. One of the characteristics is that each system, like for instance heat and light, has their own specific way of using the communication system.   This paper describes a way to connect different home control systems through an intelligent gateway, called a Home......Port. The HomePort consists of a number of Subsystem communication drivers, a virtual communication layer, an interpreter and a PC- based compiler for a high level control language, called GIL (Gateway intelligence language). The focus in this paper will be on the upper two layers in the Home...

Early childhood obesity disproportionately affects children of low socioeconomic status. Children attending Head Start are reported to have an obesity rate of 17.9%.This longitudinal study aimed to understand the relationship between cognitive stimulation at home and intake of junk food, physical activity and body size, for a nationally representative sample of 3- and 4-year old children entering Head Start. We used The Family and Child Experiences Survey 2006. Cognitive stimulation at home was measured for 1905 children at preschool entry using items from the Home Observation Measurement of the Environment Short Form. Junk food consumption and physical activity were obtained from parent interviews at kindergarten entry. BMI z scores were based on CDC national standards. We analyzed the association between early cognitive stimulation and junk food consumption, physical activity and BMI, using multinomial and binary logistic regression on a weighted sample. Children who received moderate levels of cognitive stimulation at home had a 1.5 increase in the likelihood of consuming low amounts of junk food compared to children from low cognitive stimulation environments. Children who received moderate and high levels of cognitive stimulation were two and three times, respectively, more likely to be physically active than those in low cognitive stimulation homes. No direct relationship was identified between cognitive stimulation and BMI. Prevention and treatment efforts to address early childhood obesity may consider strategies that support parents in providing cognitively stimulating home environments. Existing evidence-based programs can guide intervention in pediatric primary care.

To evaluate the prevalence of abnormalities in plasma lipid and glucose profiles among overweight and obese children and adolescents, and to assess the presence of a correlation between body mass index Z-scores and indicators of comorbidities related to both profiles. This was a multicenter cross-sectional study conducted at two outpatient clinics. The study included all 417 comers for the first visit from 2008 to 2012, aged between 7 and 18 years, with BMI above the Z-score +1. Anthropometry and blood sampling were obtained. The prevalence of dyslipidemias, hyperglycemia, and insulin resistance were evaluated, together with the correlations of these variables with the increase of Z-BMI. Dyslipidemia was observed in 43.4% of the boys and 66.1% of the girls, with no difference between genders. High glucose levels were detected in 6.2% of the individuals. Insulin resistance was present in 32.3% and 41.7% of the cases, with no statistical significance between boys and girls. Correlations between the Z-BMI were noted for triglycerides in the entire group and among girls; for HDL-c, only among girls; for glucose, a correlation was observed for the entire group, but not when stratified by gender. The indicators of insulin resistance were all correlated with Z-BMI, even when corrected for age. Overweight and obesity give origin to a high prevalence of dyslipidemia and insulin resistance. BMI Z-scores showed a weak positive correlation with glucose and triglyceride, and negative with HDL-c. In turn, the strongest positive correlation was found with insulin resistance indicators.

and glucose tolerance; as a class, these lipids are referred to as 'lipokines'. Because BAT is a specialized metabolic tissue that takes up and burns lipids and is linked to systemic metabolic homeostasis, we hypothesized that there might be thermogenic lipokines that activate BAT in response to cold. Here we...... show that the lipid 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a stimulator of BAT activity, and that its levels are negatively correlated with body-mass index and insulin sensitivity. Using a global lipidomic analysis, we found that 12,13-diHOME was increased in the circulation of humans...... and mice exposed to cold. Furthermore, we found that the enzymes that produce 12,13-diHOME were uniquely induced in BAT by cold stimulation. The injection of 12,13-diHOME acutely activated BAT fuel uptake and enhanced cold tolerance, which resulted in decreased levels of serum triglycerides...

To assess whether changes in dietary intake and physical activity pattern are associated with the annual body mass index (BMI) z-score change among adolescents. The study was conducted in public schools in the city of Piracicaba, Sao Paulo, Brazil, with a probabilistic sample of 431 adolescents participating in wave I (2004) (hereafter, baseline) and 299 in wave II (2005) (hereafter, follow-up). BMI, usual food intake, physical activity, screen time, sexual maturation and demographic variables were assessed twice. The association between annual change in food intake, physical activity, screen time, and annual BMI z-score changes were assessed by multiple regression. The study showed a positive variation in BMI z-score over one-year. Among variables related to physical activity pattern only playing videogame and using computer increased over the year. The intake of fruits and vegetables and sugar-sweetened beverages increased over one year, while the others variables showed a reduction. An increased consumption of fatty foods (β = 0.04, p = 0.04) and sweetened natural fruit juices (β = 0.05, p = 0.03) was positively associated with the rise in BMI z-score. Unhealthy dietary habits can predict the BMI z-score gain more than the physical activity pattern. The intake of fatty foods and sweetened fruit juices is associated with the BMI z-score over one year.

2014-06-01

The aim of this study was to obtain a comprehensive analysis of the physical workload of clinical staff in long-term care facilities, before and after a safe resident handling program (SRHP). Ergonomic exposures of health care workers include manual handling of patients and many non-neutral postures. A comprehensive assessment requires the integration of loads from these varied exposures into a single metric. The Postures, Activities, Tools, and Handling observational protocol, customized for health care, was used for direct observations of ergonomic exposures in clinical jobs at 12 nursing homes before the SRHP and 3, 12, 24, and 36 months afterward. Average compressive forces on the spine were estimated for observed combinations of body postures and manual handling and then weighted by frequencies of observed time for the combination. These values were summed to obtain a biomechanical index for nursing assistants and nurses across observation periods. The physical workload index (PWI) was much higher for nursing assistants than for nurses and decreased more after 3 years (-24% versus -2.5%). Specifically during resident handling, the PWI for nursing assistants decreased by 41% of baseline value. Spinal loading was higher for nursing assistants than for nurses in long-term care centers. Both job groups experienced reductions in physical loading from the SRHP, especially the nursing assistants and especially while resident handling. The PWI facilitates a comprehensive investigation of physical loading from both manual handling and non-neutral postures. It can be used in any work setting to identify high-risk tasks and determine whether reductions in one exposure are offset by increases in another.

Z factor: a new index for measuring academic research output

Full Text Available Abstract With rapid progress in scientific research activities and growing competition for funding resources, it becomes critical to effectively evaluate an individual researcher's annual academic performance, or their cumulative performance within the last 3–5 years. It is particularly important for young independent investigators, and is also useful for funding agencies when determining the productivity and quality of grant awardees. As the funding becomes increasingly limited, having an unbiased method of measuring recent performance of an individual scientist is clearly needed. Here I propose the Z factor, a new and useful way to measure recent academic performance.

Implementation of the Zuluaga-Raysmith (Z-R) model for assessment of perceived basic human needs in home health clients and caregivers.

Zuluaga, B H

2000-01-01

The Zuluaga-Raysmith (Z-R) model is a conceptual framework that incorporates accepted concepts of universal basic human needs developed by Maslow, yet removes the hierarchical nature of these. The Z-R model recognizes the existence of a health-illness continuum and accepts that an entity (individual, family, aggregate, or community) may move freely in the direction of greater health and self-actualization or towards illness and premature death. The Z-R model identifies 10 basic needs and recognizes that a perceived deficit in any one of these needs can adversely affect the level of wellness of the entity being considered. This exploratory and descriptive study used 11 nurses as interviewers. Subjects consisted of a convenience sample of homebound clients of a home health agency in a metropolitan city, and selected caregivers (n = 27). A modified functional wellness inventory (developed in 1993 by Louvenia Carter) was used with several open-ended questions, which together related to the 10 needs of the Z-R model. Reliability coefficient of the instrument was 0.84. Descriptive statistics were used to analyze the data, using means, percentages, and frequencies. Open-ended questions were grouped according to content and ranked in order of frequency. The five most pressing needs of this small sample were income; physical health; opportunity to make a contribution; mobility; and mental, emotional, social, and spiritual health (MESSH). Nurses unanimously reported that use of the instrument and the Z-R model helped them to focus on the total person, identify strengths in their clients, identify perceived needs deficits, and therefore, with the client, facilitate the preparation of a timely and cost-effective interdisciplinary plan of care to help the entity to move to a higher level of wellness despite the presence of chronic disease, disability, or impending death. These findings suggested that further research is warranted to explore the use of the Z-R model. A

Time-space trade-offs for lempel-ziv compressed indexing

DEFF Research Database (Denmark)

Bille, Philip; Ettienne, Mikko Berggren; Gørtz, Inge Li

2017-01-01

Given a string S, the compressed indexing problem is to preprocess S into a compressed representation that supports fast substring queries. The goal is to use little space relative to the compressed size of S while supporting fast queries. We present a compressed index based on the Lempel-Ziv 1977...... compression scheme. Let n, and z denote the size of the input string, and the compressed LZ77 string, respectively. We obtain the following time-space trade-offs. Given a pattern string P of length m, we can solve the problem in (i) O (m + occ lg lg n) time using O(z lg(n/z) lg lg z) space, or (ii) (m (1...... best space bound, but has a leading term in the query time of O(m(1 + lgϵ z/lg(n/z))). However, for any polynomial compression ratio, i.e., z = O(n1-δ), for constant δ > 0, this becomes O(m). Our index also supports extraction of any substring of length ℓ in O(ℓ + lg(n/z)) time. Technically, our...

Taillie, Lindsey Smith; Wang, Dantong; Popkin, Barry M

2016-06-01

Few studies, to our knowledge, have examined the longitudinal association of snacking with child body mass index (BMI), especially in China, where the incidence of overweight and obesity has increased rapidly. Our objective was to examine the longitudinal association between snacking and BMI z score and to test whether this association differs by baseline weight status. Using data from the China Health and Nutrition Survey (2006, 2009, and 2011), we characterized snack intake for 9 provinces and 3 megacities. We used linear mixed-effects models to examine longitudinally the association between snacking (none, low, medium, and high tertiles according to energy) and BMI z score in children aged 2-13 y at baseline, controlling for sex, urbanicity, parental education, physical activity, and foods consumed at meals (n = 2277 observations). We tested whether this association differed by baseline underweight, normal weight, or overweight/obese. Snacking is prevalent in Chinese children, with fruit being the most common snack. Snacking was not associated with meaningful BMI z score changes in normal-weight children. However, in children who were underweight at baseline, snacking in the top tertiles was associated with increases in BMI z scores from 2006 to 2011 (+1.2 and +1.1 BMI z score units for ages 2-6 and 7-13 y, respectively) (P overweight/obese 2- to 6-y-old children at baseline, being in the lowest snacking tertile was associated with declines in BMI z score (-3.3), whereas in overweight 7- to 13-y-old children, being in the top tertile of snacking was associated with the greatest decline in BMI z score (-2.1) (P overweight/obese children and increased BMI in underweight children. More work will be needed to monitor this relation as Chinese diets continue to westernize. © 2016 American Society for Nutrition.

Weight gain and metabolic adverse effects of second-generation antipsychotics (SGAs) have become a major concern, particularly in youth. However, the specific contribution of SGAs versus other medications or the underlying illness is unclear. In a chart review study of psychiatric outpatients aged ≤ 18 years treated with SGAs and psychiatric controls without lifetime SGA, use body mass index (BMI) z-scores between patients and controls were compared in the entire sample, patients without co-medications, diagnostic subgroups, and age subgroups. In patients with follow-up data, weight z-score change was calculated. Altogether, 592 Caucasian patients aged 4-18 (mean: 10.0) years with a psychiatric diagnosis were included. BMI z-scores in 96 youth treated with SGAs for 9.0 ± 6.1 months were significantly higher than in 496 patients without lifetime SGA use (0.81 ± 1.1 vs. 0.05 ± 1.2; pz-score differences remained significant in all age groups z-score increased significantly from -0.17 ± 1.5 to 0.25 ± 1.4 (p<0.0001) with 12.5% transitioning to overweight or obese status. These data show robust and significant differences in sex- and age-adjusted body weight and weight status in young pediatric Caucasian samples with and without use of SGAs independent of Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV-TR) (American Psychiatric Association 2000 ) diagnosis and nonantipsychotic medications. Weight status and metabolic effects of SGAs require careful attention, especially in youth.

This observational study examined the associations of built environment features around the home and workplace with cardiorespiratory fitness (CRF) based on a treadmill test and body mass index (BMI) (weight (kg)/height (m)2). The study included 8,857 adults aged 20–88 years who completed a preventive medical examination in 2000–2007 while living in 12 Texas counties. Analyses examining workplace neighborhood characteristics included a subset of 4,734 participants. Built environment variables were derived around addresses by using geographic information systems. Models were adjusted for individual-level and census block group–level demographics and socioeconomic status, smoking, BMI (in CRF models), and all other home or workplace built environment variables. CRF was associated with higher intersection density, higher number of private exercise facilities around the home and workplace, larger area of vegetation around the home, and shorter distance to the closest city center. Aside from vegetation, these same built environment features around the home were also associated with BMI. Participants who lived and worked in neighborhoods in the lowest tertiles for intersection density and the number of private exercise facilities had lower CRF and higher BMI values than participants who lived and worked in higher tertiles for these variables. This study contributes new evidence to suggest that built environment features around homes and workplaces may affect health. PMID:23942215

Working with builder partners on a test homes allows for vetting of whole-house building strategies to eliminate any potential unintended consequences prior to implementing these solution packages on a production scale. To support this research, CARB partnered with Preferred Builders Inc. on a high-performance test home in Old Greenwich, CT. The philosophy and science behind the 2,700 ft2 'Performance House' was based on the premise that homes should be safe, healthy, comfortable, durable, efficient, and adapt with the homeowners. The technologies and strategies used in the 'Performance House' were not cutting-edge, but simply 'best practices practiced'. The focus was on simplicity in construction, maintenance, and operation. When seeking a 30% source energy savings targets over a comparable 2009 IECC code-built home in the cold climate zone, nearly all components of a home must be optimized. Careful planning and design are critical. To help builders and architects seeking to match the performance of this home, a step-by-step guide through the building shell components of DOE's Challenge Home are provided in a pictorial story book. The end result was a DOE Challenge Home that achieved a HERS Index Score of 20 (43 without PV, the minimum target was 55 for compliance). This home was also awarded the 2012 HOBI for Best Green Energy Efficient Home from the Home Builders & Remodelers Association of Connecticut.

The objective of this research was to evaluate diet quality in elderly nursing home residents and to point out the critical dietary components. The participants (277 females and 62 males) were recruited from all elderly nursing homes in Zagreb and each of elderly nursing homes was equally represented in this study. The age of subjects was ranging from 61 to 93 years; most of the females (53.4%) and males (53.2%) were between 70 and 80 years old. The dietary data from the multi pass 24-hour recall were used to compute the Diet Quality Index Revised (DQI-R). DQI-R is an instrument that provides a summary assessment of a diet's overall healthfulness and is based on ten different aspects, including recommendations for both nutrient and food types. Pearson correlation analysis was used to compare the total DQI-R score with dietetic parameters and t-test was calculated between mean values of all the components of DQI-R as well as for total DQI-R score for men and women. The mean DQI-R score for the 339 sample was 62.1 +/- 11.7. The biggest number of participants satisfied recommendations about dietary cholesterol intake (88.5% of participants) and dietary moderation score (71.1% of participants) but nobody satisfied recommendation about dietary diversity score. Only 3.2% of subjects had an adequate calcium intake (6.5% of male participants and only 2.5% of female participants). Recommended servings of fruit intake were satisfied by 19.8% of population, 30.4% satisfied vegetables recommendations and 38.6% recommendations for grains. According to DQI-R, beside positive dietary habits regarding dietary moderation and dietary cholesterol intake the population of elderly nursing home residents in the capital of Croatia needs improvement in other dietary habits in order to enhance successful aging.

To help builders and architects seeking to match the performance of this home, a step-by-step guide through the building shell components of DOE's Challenge Home are provided in a pictorial story book. The end result was a DOE Challenge Home that achieved a HERS Index Score of 20 (43 without PV, the minimum target was 55 for compliance). This home was also awarded the 2012 HOBI for Best Green Energy Efficient Home from the Home Builders & Remodelers Association of Connecticut.

Sieve of Eratosthenes benchmarks for the Z8 FORTH microcontroller

Energy Technology Data Exchange (ETDEWEB)

Edwards, R.

1989-02-01

This report presents benchmarks for the Z8 FORTH microcontroller system that ORNL uses extensively in proving concepts and developing prototype test equipment for the Smart House Project. The results are based on the sieve of Eratosthenes algorithm, a calculation used extensively to rate computer systems and programming languages. Three benchmark refinements are presented,each showing how the execution speed of a FORTH program can be improved by use of a particular optimization technique. The last version of the FORTH benchmark shows that optimization is worth the effort: It executes 20 times faster than the Gilbreaths' widely-published FORTH benchmark program. The National Association of Home Builders Smart House Project is a cooperative research and development effort being undertaken by American home builders and a number of major corporations serving the home building industry. The major goal of the project is to help the participating organizations incorporate advanced technology in communications,energy distribution, and appliance control products for American homes. This information is provided to help project participants use the Z8 FORTH prototyping microcontroller in developing Smart House concepts and equipment. The discussion is technical in nature and assumes some experience with microcontroller devices and the techniques used to develop software for them. 7 refs., 5 tabs.

Properties of power series of analytic in a bidisc functions of bounded $\\mathbf{L}$-index in joint variables

Full Text Available We generalized some criteria of boundedness of $\\mathbf{L}$-index in joint variables for analytic in a bidisc functions, where $\\mathbf{L}(z=(l_1(z_1,z_2,$ $l_{2}(z_1,z_2,$ $l_j:\\mathbb{D}^2\\to \\mathbb{R}_+$ is a continuous function, $j\\in\\{1,2\\},$ $\\mathbb{D}^2$ is a bidisc $\\{(z_1,z_2\\in\\mathbb{C}^2: |z_1|<1,|z_2|<1\\}.$ The propositions describe a behaviour of power series expansion on a skeleton of a bidisc. We estimated power series expansion by a dominating homogeneous polynomial with the degree that does not exceed some number depending only from radii of bidisc. Replacing universal quantifier by existential quantifier for radii of bidisc, we also proved sufficient conditions of boundedness of $\\mathbf{L}$-index in joint variables for analytic functions which are weaker than necessary conditions.

New method for calculating the coupling coefficient in graded index optical fibers

Science.gov (United States)

Savović, Svetislav; Djordjevich, Alexandar

2018-05-01

A simple method is proposed for determining the mode coupling coefficient D in graded index multimode optical fibers. It only requires observation of the output modal power distribution P(m, z) for one fiber length z as the Gaussian launching modal power distribution changes, with the Gaussian input light distribution centered along the graded index optical fiber axis (θ0 = 0) without radial offset (r0 = 0). A similar method we previously proposed for calculating the coupling coefficient D in a step-index multimode optical fibers where the output angular power distributions P(θ, z) for one fiber length z with the Gaussian input light distribution launched centrally along the step-index optical fiber axis (θ0 = 0) is needed to be known.

2004-01-01

Undernutrition is present among 33% of nursing home residents in Denmark. Hence, it is relevant to examine the meal situation at nursing homes to single out factors that may increase or reduce the residents' food intake. in the ongoing Danish nursing home debate it is claimed that a new type...... of nursing home improves the residents' meal situation with a positive effect on nutrition. The aim of this work is to test the general hypothesis that (i) residents appreciate the meal situation in these nursing homes and (ii) nutritional status of the residents is improved in this type of nursing home....... This study was carried out in four Danish nursing homes at various locations in Denmark. The methods used are qualitative interviews and observations at four nursing homes in combination with measurement of body mass index (BMI) at two of the four nursing homes.

Directory of Open Access Journals (Sweden)

Carlos Alberto Nogueira-de-Almeida

2018-05-01

Full Text Available Objective: To evaluate the prevalence of abnormalities in plasma lipid and glucose profiles among overweight and obese children and adolescents, and to assess the presence of a correlation between body mass index Z-scores and indicators of comorbidities related to both profiles. Methods: This was a multicenter cross-sectional study conducted at two outpatient clinics. The study included all 417 comers for the first visit from 2008 to 2012, aged between 7 and 18 years, with BMI above the Z-score +1. Anthropometry and blood sampling were obtained. The prevalence of dyslipidemias, hyperglycemia, and insulin resistance were evaluated, together with the correlations of these variables with the increase of Z-BMI. Results: Dyslipidemia was observed in 43.4% of the boys and 66.1% of the girls, with no difference between genders. High glucose levels were detected in 6.2% of the individuals. Insulin resistance was present in 32.3% and 41.7% of the cases, with no statistical significance between boys and girls. Correlations between the Z-BMI were noted for triglycerides in the entire group and among girls; for HDL-c, only among girls; for glucose, a correlation was observed for the entire group, but not when stratified by gender. The indicators of insulin resistance were all correlated with Z-BMI, even when corrected for age. Conclusions: Overweight and obesity give origin to a high prevalence of dyslipidemia and insulin resistance. BMI Z-scores showed a weak positive correlation with glucose and triglyceride, and negative with HDL-c. In turn, the strongest positive correlation was found with insulin resistance indicators. Resumo: Objetivo: Avaliar a prevalência de anormalidades nos perfis lipídico e glicêmico entre crianças e adolescentes com sobrepeso e obesidade e também verificar se existe correlação entre os escores-z de índice de massa corporal (z-IMC e indicadores de comorbidades ligados a esses perfis. Métodos: Estudo de corte transversal

Pharmacological inhibition of caspase and calpain proteases: a novel strategy to enhance the homing responses of cord blood HSPCs during expansion.

Directory of Open Access Journals (Sweden)

V M Sangeetha

Full Text Available BACKGROUND: Expansion of hematopoietic stem/progenitor cells (HSPCs is a well-known strategy employed to facilitate the transplantation outcome. We have previously shown that the prevention of apoptosis by the inhibition of cysteine proteases, caspase and calpain played an important role in the expansion and engraftment of cord blood (CB derived HSPCs. We hypothesize that these protease inhibitors might have maneuvered the adhesive and migratory properties of the cells rendering them to be retained in the bone marrow for sustained engraftment. The current study was aimed to investigate the mechanism of the homing responses of CB cells during expansion. METHODOLOGY/PRINCIPAL FINDINGS: CB derived CD34(+ cells were expanded using a combination of growth factors with and without Caspase inhibitor -zVADfmk or Calpain 1 inhibitor- zLLYfmk. The cells were analyzed for the expression of homing-related molecules. In vitro adhesive/migratory interactions and actin polymerization dynamics of HSPCs were assessed. In vivo homing assays were carried out in NOD/SCID mice to corroborate these observations. We observed that the presence of zVADfmk or zLLYfmk (inhibitors caused the functional up regulation of CXCR4, integrins, and adhesion molecules, reflecting in a higher migration and adhesive interactions in vitro. The enhanced actin polymerization and the RhoGTPase protein expression complemented these observations. Furthermore, in vivo experiments showed a significantly enhanced homing to the bone marrow of NOD/SCID mice. CONCLUSION/SIGNIFICANCE: Our present study reveals another novel aspect of the regulation of caspase and calpain proteases in the biology of HSPCs. The priming of the homing responses of the inhibitor-cultured HSPCs compared to the cytokine-graft suggests that the modulation of these proteases may help in overcoming the major homing defects prevalent in the expansion cultures thereby facilitating the manipulation of cells for transplant

Family meal frequency has been shown to be strongly associated with better dietary intake; however, associations with weight status have been mixed. Family meals-focused randomized controlled trials with weight outcomes have not been previously conducted. Therefore, this study purpose was to describe weight-related outcomes of the HOME Plus study, the first family meals-focused randomized controlled trial to prevent excess weight gain among youth. Families (n = 160 8-12-year-old children and their parents/guardians) were randomized to intervention (n = 81) or control (n = 79) groups. Data were collected at baseline (2011-2012), post-intervention (12-months post-baseline) and follow-up (21-months post-baseline). The intervention included ten monthly group sessions (nutrition education; hands-on meal and snack planning, preparation, and skill development; screen time reductions) and five motivational, goal-setting phone calls. The main outcome was child body mass index (BMI) z-score. General linear models, adjusted for baseline values and demographics, showed no significant treatment group differences in BMI z-scores at post-intervention or follow-up; however, a promising reduction in excess weight gain was observed. Post-hoc stratification by pubertal onset indicated prepubescent children in the intervention group had significantly lower BMI z-scores than their control group counterparts. The study used a strong theoretical framework, rigorous design, quality measurement and a program with high fidelity to test a family meals-focused obesity prevention intervention. It showed a modest decrease in excess weight gain. The significant intervention effect among prepubescent children suggests the intervention may be more efficacious among relatively young children, although more research with appropriately powered samples are needed to replicate this finding. This study is registered at www.clinicaltrials.gov NCT01538615. Registered 01/17/2012.

Parillo, M; Licenziati, M R; Vacca, M; De Marco, D; Iannuzzi, A

2012-07-01

A low glycemic index (LGI) diet has been proposed as a treatment for obesity in adults; few studies have evaluated LGI diets in obese children. The purpose of the study was to compare the effects of two diets, with similar energy intakes, but different glycemic indexes in a pediatric outpatient setting. A parallel- group, randomized controlled trial was conducted, and 22 obese outpatient children with a body mass index (BMI) Z-score >2 (11 females and 11 males, BMI 28.9±2.9 kg/m²) were included in the study. Patients were randomly allocated to a hypocaloric LGI (GI:60), or to a hypocaloric high glycemic index (HGI) diet (GI:90). The LGI and HGI diets were almost equivalent for macronutrient composition. Anthropometric and biochemical parameters were measured at baseline and after 6 months. In both groups there were significant decreases in BMI, BMI Z-score, blood pressure, and high-sensitivity C-reactive protein. Only LGI diets produced a significant decrease in waist circumference and homeostasis model assessment. Analysis of variance demonstrated that the BMI Z-score decrease from baseline values was significantly greater after the LGI diet than after the HGI diet [-0.20 (95% confidence interval (CI) -0.29 to -0.10) vs -0.34 (95%CI -0.43 to -0.24)], mean difference between groups -0.14 (95%CI -0.27 to -0.01), pdiet (phypocaloric LGI diet has beneficial metabolic effects in comparison to a hypocaloric HGI diet in obese children.

Seyed Abbas Kazemi

2012-01-01

Full Text Available Home appliances are considered as one of low margin and competitive industry in the world. This industry often needs significant amount of investment and resources and it often faces with some challenges during economic crises. In this paper, we present a framework for organizational excellence to detect any possible problems in home appliances industry. The proposed framework of this paper is used for a real-world case study of Iranian home appliances. The results of our survey indicate that there are four major dimensions involved with this industry including facilities, knowledge and skills, environment and vision. There are three criteria associated with facilities with 30 indexes, 14 criteria associated with knowledge and skills with 144 indexes, three criteria involved with environment with 33 indexes and five criteria linked with vision with 53 indexes. Therefore, home appliances in our case study needs 4 dimensions for achieving the organizational excellence.

Optimal joint scheduling of electrical and thermal appliances in a smart home environment

International Nuclear Information System (INIS)

Shirazi, Elham; Zakariazadeh, Alireza; Jadid, Shahram

2015-01-01

Highlights: • Thermal appliances are scheduled based on desired temperature and energy prices. • A discomfort index has been introduced within the home energy scheduling model. • Appliances are scheduled based on activity probability and desired options. • Starting probability depends on the social random factor and consumption behavior. - Abstract: With the development of home area network, residents have the opportunity to schedule their power usage in the home by themselves aiming at reducing electricity expenses. Moreover, as renewable energy sources are deployed in home, a home energy management system needs to consider both energy consumption and generation simultaneously to minimize the energy cost. In this paper, a smart home energy management model has been presented in which electrical and thermal appliances are jointly scheduled. The proposed method aims at minimizing the electricity cost of a residential customer by scheduling various type of appliances considering the residents consumption behavior, seasonal probability, social random factor, discomfort index and appliances starting probability functions. In this model, the home central controller receives the electricity price information, environmental factors data as well as the resident desired options in order to optimally schedule appliances including electrical and thermal. The scheduling approach is tested on a typical home including variety of home appliances, a small wind turbine, photovoltaic panel, combined heat and power unit, boiler and electrical and thermal storages over a 24-h period. The results show that the scheduling of different appliances can be reached simultaneously by using the proposed formulation. Moreover, simulation results evidenced that the proposed home energy management model exhibits a lower cost and, therefore, is more economical.

The home environment: A mediator of nutrition knowledge and diet quality in adolescents.

Science.gov (United States)

Tabbakh, Tamara; Freeland-Graves, Jean H

2016-10-01

The objective of this research was to assess adherence to the Healthy Eating Index-2010 of mothers and their adolescents (11-14 years old) and to examine the role of the home environment as a mediator of maternal nutrition knowledge and adolescent diet quality. It is hypothesized that mothers with greater knowledge impact the diet quality of their adolescents by creation of healthier home environments. A sample of 206 mother-adolescent dyads separately completed the Multidimensional Home Environment Scale, a Food Frequency Questionnaire, and a Nutrition Knowledge Scale. Body mass index-for-age percentiles were derived from weight and height measurements obtained by researcher; diet quality was estimated via the Healthy Eating Index (HEI)-2010. Percent of maximum score on nutrition knowledge for both mothers and adolescents were poor, with lowest scores on recommendations of healthy eating and physical activity (48% and 19%, respectively). A model of maternal nutrition knowledge (independent variable) and adolescent diet quality (dependent variable) indicated that greater knowledge was associated with higher scores on total fruit (p = 0.02), whole grains (p = 0.05), seafood and plant proteins (p = 0.01), and overall diet quality (p empty calories (p = 0.01). Inclusion of the home environment as a mediator yielded significant estimates of the indirect effect (β = 0.61, 95% CI: 0.3-1.0). Within the home environment, psychological (β = 0.46), social (β = 0.23), and environmental (β = 0.65) variables were all significant mediators of nutrition knowledge on diet quality. These results emphasize the importance of maternal nutrition knowledge and the mediating effect of the home environment on the diet quality of adolescents. Copyright © 2016 Elsevier Ltd.

Uninvolved Maternal Feeding Style Moderates the Association of Emotional Overeating to Preschoolers' Body Mass Index z-Scores.

Science.gov (United States)

Hankey, Maren; Williams, Natalie A; Dev, Dipti

2016-09-01

To examine the relation between preschoolers' eating behaviors and body mass index (BMI) z-scores (BMIz) and the moderating role of permissive parent feeding styles in these associations. Cross-sectional study involving mothers' report of food-related parenting styles and child eating behaviors. Small city in southern Mississippi. Mother-preschooler dyads (n = 104). Child body BMIz. Moderated multiple regression. An uninvolved feeding style moderated the relationship between emotional eating and BMIz such that children with higher emotional overeating scores had higher a BMIz in the presence of an uninvolved feeding style (B = 2.16; P = .01). An uninvolved feeding style may be a risk factor for higher BMIz in preschoolers who tend to overeat to cope with negative emotions. For other children in this population, self-regulatory aspects of eating may be more important than mothers' feeding style in the maintenance of healthy weight.

PBFA Z, a new 60-TW/5-MJ electrical accelerator located at Sandia National Laboratories, is now the world's most powerful z-pinch driver. PBFA Z stores 11.4 MJ in its 36 Marx generators, couples 5 MJ into a 60-TW/105-ns FWHM pulse to the 120-mΩ water transmission lines, and delivers 3.0 MJ and 50 TW of electrical energy to the z-pinch load. Depending on load parameters, we attain peak load currents of 16-20 MA with a current rise time of ∼105ns with wire-array z-pinch loads. We have extended the x-ray performance of tungsten wire-array z pinches from earlier Saturn experiments. Using a 2-cm-radius, 2-cm-long tungsten wire array with 240, 7.5-μm diameter wires (4.1-mg mass), we achieved an x-ray power of 210 TW and an x-ray energy of 1.9 MJ. Preliminary spectral measurements suggest a mostly optically-thick, Planckian-like radiator below 1000 eV. Data indicate ∼100kJ of x rays radiated above 1000 eV. An intense z-pinch x-ray source with an overall coupling efficiency greater than 15% has been demonstrated. copyright 1997 American Institute of Physics

Lee, Da-Young; Lee, Mi-Yeon; Sung, Ki-Chul

2018-06-01

This paper investigated the impact of A Body Shape Index (ABSI) on the risk of all-cause mortality compared with the impact of waist circumference (WC) and body mass index (BMI). This paper reviewed data of 213,569 Korean adults who participated in health checkups between 2002 and 2012 at Kangbuk Samsung Hospital in Seoul, Korea. A multivariate Cox proportional hazard analysis was performed on the BMI, WC, and ABSI z score continuous variables as well as quintiles. During 1,168,668.7 person-years, 1,107 deaths occurred. As continuous variables, a significant positive relationship with the risk of all-cause death was found only in ABSI z scores after adjustment for age, sex, current smoking, alcohol consumption, regular exercise, presence of diabetes or hypertension, and history of cardiovascular diseases. In Cox analysis of quintiles, quintile 5 of the ABSI z score showed significantly increased hazard ratios (HRs) for mortality risk (HR [95% CI] was 1.32 [1.05-1.66]), whereas the risk for all-cause mortality, on the other hand, decreased in quintiles 3 through 5 of BMI and WC compared with their first quintiles after adjusting for several confounders. This study showed that the predictive value of ABSI for mortality risk was strong for a sample of young Asian participants and that its usefulness was better than BMI or WC. © 2018 The Obesity Society.

Development of a Z-pinch-driven ICF hohlraum concept on Z

International Nuclear Information System (INIS)

Cuneo, M.E.; Porter, J.L. Jr.; Vesey, R.A.

1999-01-01

Recent development of high power z-pinches (> 150 MW) on the Z driver has permitted the study of high-temperature, radiation-driven hohlraums. Three complementary, Z-pinch source-hohlraum-ICF capsule configurations are being developed to harness the x-ray output of these Z-pinch's. These are the dynamic-hohlraum, static-wall hohlraum, and Z-pinch-driven hohlraum concepts. Each has different potential strengths and concerns.

1999-07-01

Recent development of high power z-pinches (> 150 MW) on the Z driver has permitted the study of high-temperature, radiation-driven hohlraums. Three complementary, Z-pinch source-hohlraum-ICF capsule configurations are being developed to harness the x-ray output of these Z-pinch's. These are the dynamic-hohlraum, static-wall hohlraum, and Z-pinch-driven hohlraum concepts. Each has different potential strengths and concerns. In this paper, the authors report on the first experiments with the Z-pinch-driven hohlraum (ZPDH) concept. A high-yield ICF capsule design for this concept appears feasible, when driven by z-pinches from a 60 MA-class driver. Initial experiments characterize the behavior of the spoke array on Z-pinch performance and x-ray transmission, and the uniformity of radiation flux incident on a foam capsule in the secondary, for a single-sided drive. Measurements of x-ray wall re-emission power and spectrum, radiation temperatures, spoke-plasma location, and drive uniformity will be presented and compared with 0-D energetics, 2-D Lasnex rad-hydro, and 3-D radiosity calculations of energy transport and drive uniformity.

To develop a portable risk index for falls. Risk factors were chosen from previously established factors then we added several environmental factors to the risk index; previous falls in the last 12 month, trippig or stumbling, inability to ascend or descend stairs without help, decreased walking speed, inability to cross a road within the green signal interval, inability to walk 1km without a break, inability to stand on one leg for 5 seconds (eyes open), using a cane, inability to wring out a towel, dizziness or faintness, stooped or rounded back, knee joint pain, visual disturbance, hearing disturbance, cognitive decline, fear of falling, receiving 5 or more prescribed drugs, sensation of darkness at home, obstacles inside, barrier on the carpet or floor, using steps daily at home, steep slopes around home. The questionnaire sheet was completed by 2,439 community-dwelling elderly subjects (76.3 +/- 7.4 years old). The frequency of each items of fall risk index was compared between fallers (history of fall within one year) and non-fallers. Multiple regression analysis was performed to identify independent risk factors for previous falls. Except barrier, step use and steep slope around home, all items in the fall risk index were more frequent in fallers. Multivariate analysis revealed that tripping or stumbling, inability to cross a road within the green signal interval, dizziness or faintness, obstacles inside, inability to wring out a towel, cane use and knee joint pain were independent risk factors for previous falls. These 7 selected items were further analyzed as predictors. The maximum sum of sensitivity and specificity was reached at the cut-off point of 2/3 (sensitivity 0.65, specificity 0.72) by receiver operating curve. Portable fall risk index is useful for clinical settings to identify high-risk subjects.

Face centered cubic SnSe as a Z2 trivial Dirac nodal line material

OpenAIRE

Tateishi, Ikuma; Matsuura, Hiroyasu

2018-01-01

The presence of Dirac nodal line in the time-reversal and inversion symmetric system is dictated by Z2 index when spin-orbit interaction is absent. With the first principles calculation, we show that the Dirac nodal line can emerge in Z2 trivial material by calculating the band structure of SnSe of face centered cubic lattice as an example and it becomes a topological crystalline insulator when spin-orbit interaction is taken into account. We clarify the origin of the Dirac nodal line by obta...

Trisomy 13 (T13) is accompanied by severe complications, and it can be challenging to achieve long-term survival without aggressive treatment. However, recently, some patients with T13 have been receiving home care. We conducted this study to investigate factors related to home health-care transition for patients with T13.We studied 28 patients with T13 born between January 2000 and December 2014. We retrospectively compared nine home care transition patients (the home care group) and 19 patients that died during hospitalization (the discharge at death group). The median gestational age of the patients was 36.6 weeks, with a median birth weight of 2,047 g. Currently, three patients (11%) have survived, and 25 (89%) have died. The home care group exhibited a significantly longer gestational age (38.9 vs. 36.3 weeks, p = 0.039) and significantly larger occipitofrontal circumference Z score (-0.04 vs. -0.09, p = 0.019). Congenital heart defects (CHD) was more frequent in the discharge at death group, with six patients in the home care group and 18 patients in the discharge at death group (67% vs. 95%, p = 0.047), respectively. Survival time was significantly longer in the home care group than in the discharge at death group (171 vs. 19 days, p = 0.012). This study has shown that gestational age, occipitofrontal circumference Z score at birth, and the presence of CHD are helpful prognostic factors for determining treatment strategy in patients with T13. © 2017 Wiley Periodicals, Inc.

2014-01-01

UK care home residents are often poorly served by existing healthcare arrangements. Published descriptions of residents' health status have been limited by lack of detail and use of data derived from surveys drawn from social, rather than health, care records. to describe in detail the health status and healthcare resource use of UK care home residents a 180-day longitudinal cohort study of 227 residents across 11 UK care homes, 5 nursing and 6 residential, selected to be representative for nursing/residential status and dementia registration. Barthel index (BI), Mini-mental state examination (MMSE), Neuropsychiatric index (NPI), Mini-nutritional index (MNA), EuroQoL-5D (EQ-5D), 12-item General Health Questionnaire (GHQ-12), diagnoses and medications were recorded at baseline and BI, NPI, GHQ-12 and EQ-5D at follow-up after 180 days. National Health Service (NHS) resource use data were collected from databases of local healthcare providers. out of a total of 323, 227 residents were recruited. The median BI was 9 (IQR: 2.5-15.5), MMSE 13 (4-22) and number of medications 8 (5.5-10.5). The mean number of diagnoses per resident was 6.2 (SD: 4). Thirty per cent were malnourished, 66% had evidence of behavioural disturbance. Residents had contact with the NHS on average once per month. residents from both residential and nursing settings are dependent, cognitively impaired, have mild frequent behavioural symptoms, multimorbidity, polypharmacy and frequently use NHS resources. Effective care for such a cohort requires broad expertise from multiple disciplines delivered in a co-ordinated and managed way.

The London Health Sciences Centre Home Safety Program (HSP) provides safety devices, education, a safety video, and home safety checklist to all first-time parents for the reduction of childhood home injuries. The objective of this study was to evaluate the HSP for the prevention of home injuries in children up to 2 years of age. A program evaluation was performed with follow-up survey, along with an interrupted time series analysis of emergency department (ED) visits for home injuries 5 years before (2007-2013) and 2 years after (2013-2015) implementation. Spatial analysis of ED visits was undertaken to assess differences in home injury rates by dissemination areas controlling differences in socioeconomic status (i.e., income, education, and lone-parent status) at the neighborhood level. A total of 3,458 first-time parents participated in the HSP (a 74% compliance rate). Of these, 20% (n = 696) of parents responded to our questionnaire, with 94% reporting the program to be useful (median, 6; interquartile range, 2 on a 7-point Likert scale) and 81% learning new strategies for preventing home injuries. The median age of the respondent's babies were 12 months (interquartile range, 1). The home safety check list was used by 87% of respondents to identify hazards in their home, with 95% taking action to minimize the risk. The time series analysis demonstrated a significant decline in ED visits for home injuries in toddlers younger than2 years of age after HSP implementation. The declines in ED visits for home injuries remained significant over and above each socioeconomic status covariate. Removing hazards, supervision, and installing safety devices are key facilitators in the reduction of home injuries. Parents found the HSP useful to identify hazards, learn new strategies, build confidence, and provide safety products. Initial finding suggests that the program is effective in reducing home injuries in children up to 2 years of age. Therapeutic/care management study

Siew, Lam Weng; Jaaman, Saiful Hafizah Hj.; Ismail, Hamizun bin

2014-09-01

Enhanced index tracking is a popular form of portfolio management in stock market investment. Enhanced index tracking aims to construct an optimal portfolio to generate excess return over the return achieved by the stock market index without purchasing all of the stocks that make up the index. The objective of this paper is to construct an optimal portfolio using mixed-integer programming model which adopts regression approach in order to generate higher portfolio mean return than stock market index return. In this study, the data consists of 24 component stocks in Malaysia market index which is FTSE Bursa Malaysia Kuala Lumpur Composite Index from January 2010 until December 2012. The results of this study show that the optimal portfolio of mixed-integer programming model is able to generate higher mean return than FTSE Bursa Malaysia Kuala Lumpur Composite Index return with only selecting 30% out of the total stock market index components.

Effects of work stress and home stress on autonomic nervous function in Japanese male workers.

Science.gov (United States)

Maeda, Eri; Iwata, Toyoto; Murata, Katsuyuki

2015-01-01

Autonomic imbalance is one of the important pathways through which psychological stress contributes to cardiovascular diseases/sudden death. Although previous studies have focused mainly on stress at work (work stress), the association between autonomic function and stress at home (home stress) is still poorly understood. The purpose was to clarify the effect of work/home stress on autonomic function in 1,809 Japanese male workers. We measured corrected QT (QTc) interval and QT index on the electrocardiogram along with blood pressure and heart rate. Participants provided self-reported information about the presence/absence of work/home stress and the possible confounders affecting QT indicators. Home stress was related positively to QT index (p=0.040) after adjusting for the possible confounders, though work stress did not show a significant relation to QTc interval or QT index. The odds ratio of home stress to elevated QT index (≥105) was 2.677 (95% CI, 1.050 to 6.822). Work/home stress showed no significant relation to blood pressure or heart rate. These findings suggest that autonomic imbalance, readily assessed by QT indicators, can be induced by home stress in Japanese workers. Additional research is needed to identify different types of home stress that are strongly associated with autonomic imbalance.

2018-03-01

To evaluate the feasibility and safety of home rehabilitation of the hand using a robotic glove, and, in addition, its effectiveness, in hemiplegic patients after stroke. In this non-randomized pilot study, 21 hemiplegic stroke patients (Ashworth spasticity index ≤ 3) were prescribed, after in-hospital rehabilitation, a 2-month home-program of intensive hand training using the Gloreha Lite glove that provides computer-controlled passive mobilization of the fingers. Feasibility was measured by: number of patients who completed the home-program, minutes of exercise and number of sessions/patient performed. Safety was assessed by: hand pain with a visual analog scale (VAS), Ashworth spasticity index for finger flexors, opponents of the thumb and wrist flexors, and hand edema (circumference of forearm, wrist and fingers), measured at start (T0) and end (T1) of rehabilitation. Hand motor function (Motricity Index, MI), fine manual dexterity (Nine Hole Peg Test, NHPT) and strength (Grip test) were also measured at T0 and T1. Patients performed, over a mean period 56 (49-63) days, a total of 1699 (1353-2045) min/patient of exercise with Gloreha Lite, 5.1 (4.3-5.8) days/week. Seventeen patients (81%) completed the full program. The mean VAS score of hand pain, Ashworth spasticity index and hand edema did not change significantly at T1 compared to T0. The MI, NHPT and Grip test improved significantly (p = 0.0020, 0.0156 and 0.0024, respectively) compared to baseline. Gloreha Lite is feasible and safe for use in home rehabilitation. The efficacy data show a therapeutic effect which need to be confirmed by a randomized controlled study.

Objectives (1) To investigate differences in health-related, home and neighbourhood environmental variables between Liverpool children living in areas of high deprivation (HD) and medium-to-high deprivation (MD) and (2) to assess associations between these perceived home and neighbourhood environments and health-related variables stratified by deprivation group. Design Cross-sectional study. Setting 10 Liverpool primary schools in 2014. Participants 194 children aged 9–10 years. Main outcome measures Health-related variables (self-reported physical activity (PA) (Physical Activity Questionnaire for Older Children, PAQ-C), cardiorespiratory fitness, body mass index (BMI) z-scores, waist circumference), home environment variables: (garden/backyard access, independent mobility, screen-based media restrictions, bedroom media) and neighbourhood walkability (Neighbourhood Environment Walkability Scale for Youth, NEWS-Y). Explanatory measures Area deprivation. Results There were significant differences between HD and MD children's BMI z-scores (p<0.01), waist circumference (p<0.001) and cardiorespiratory fitness (p<0.01). HD children had significantly higher bedroom media availability (p<0.05) and independent mobility scores than MD children (p<0.05). MD children had significantly higher residential density and neighbourhood aesthetics scores, and lower crime safety, pedestrian and road traffic safety scores than HD children, all of which indicated higher walkability (p<0.01). HD children's BMI z-scores (β=−0.29, p<0.01) and waist circumferences (β=−0.27, p<0.01) were inversely associated with neighbourhood aesthetics. HD children's PA was negatively associated with bedroom media (β=−0.24, p<0.01), and MD children's PA was positively associated with independent mobility (β=0.25, p<0.01). MD children's independent mobility was inversely associated with crime safety (β=−0.28, p<0.01) and neighbourhood aesthetics (β=−0.24, p<0.05). Conclusions Children

In particular, we examine how advanced computationally expensive services can be provided by using a cloud computing approach to overcome the limitations of the hardware available at the user's home. To this end, we integrate two wireless low-cost, off-the-shelf systems in this work, namely, the service robot Rovio and the home automation system Z-wave. Cloud computing is used to enhance the capabilities of these systems so that advanced sensing and interaction services based on image processing and voice recognition can be offered.

PBFA Z: A 20-MA z-pinch driver for plasma radiation sources

International Nuclear Information System (INIS)

Spielman, R.B.; Breeze, S.F.; Deeney, C.

1996-01-01

Sandia National Laboratories is completing a major modification to the PBFA-II facility. PBFA Z will be a z-pinch driver capable of delivering up to 20 MA to a z-pinch load. It optimizes the electrical coupling to the implosion energy of z pinches at implosion velocities of ∼ 40 cm/μs. Design constraints resulted in an accelerator with a 0.12-Ω impedance, a 10.25-nH inductance, and a 120-ns pulse width. The design required new water transmission lines, insulator stack, and vacuum power feeds. Current is delivered to the z-pinch load through four, self-magnetically-insulated vacuum transmission lines and a double post-hole convolute. A variety of design codes are used to model the power flow. These predict a peak current of 20 MA to a z-pinch load having a 2-cm length, a 2-cm radius, and a 15--mg mass, coupling 1.5 MJ into kinetic energy. We present 2-D Rad-Hydro calculations showing MJ x-ray outputs from tungsten wire-array z pinches

Institute of Scientific and Technical Information of China (English)

无

2006-01-01

The strapdown homing guidance system for some ammunition was mainly studied. A strong tracking Kalman filter was designed for the strapdown homing guidance system using the information measured by the strapdown homing seeker to estimate relative movement variables between the ammunition and target. Then the optimal proportional law, which using the estimated information, guided the ammunition. Simulation results show that the designed strapdown homing guidance system with strong tracking Kalman filter can attack the maneuvering target effectively, and satisfy the performance index for the guided ammunition system.

Obesity is a public health problem that disproportionately affects low-income populations. Moreover, participation in Supplemental Nutrition Assistance Program (SNAP) has been associated with obesity among low-income women. The goal of this study was to determine the impact of intrapersonal, home environment, community and social factors on diet quality and body mass index (BMI) of low-income women participating in SNAP. This study also aimed to examine the role of these factors in mediating the relationship between food insecurity and diet quality, and BMI. A total of 152 women receiving SNAP benefits were recruited from low-income neighborhood centers and housing communities, and administered a demographics questionnaire, the United States adult food security scale, food frequency questionnaire, and multi-dimensional home environment scale (MHES). They also were measured for height and weight to calculate BMI. The Dietary Guidelines Adherence Index 2015 was used to measure diet quality. Regression analyses were conducted to determine the MHES subscales that were significant predictors of diet quality and BMI. The Preacher and Hayes mediation model was used to evaluate the mediation of the relationship between food insecurity and diet quality, and BMI by the MHES. Emotional eating resistance and favorable social eating behaviors were positively associated with diet quality; whereas emotional eating resistance, lower availability of unhealthy food at home, neighborhood safety and favorable social eating behaviors were inversely associated with BMI in women participating in SNAP. The MHES significantly mediated the relationship between food insecurity and BMI. These results emphasize the importance of intrapersonal, home environment, community and social factors in mediating the relationship between food insecurity and BMI in low-income women.

Faydalı, Saide; Çetinkaya, Funda

Sleep is important for health and quality of life in the elderly, and sleep disturbances are reported to be associated with many of the adverse medical conditions. This research was carried out to evaluate the effect of inhalation of lavender oil on sleep quality of nursing home residents. A questionnaire was used to evaluate sociodemographic characteristics and sleeping properties of the 30 volunteers, enrolled. Pittsburgh Sleep Quality Index was applied as a pre- and posttest to measure sleep quality of individuals who inhaled lavender oil drops on the pillows every evening for a week before sleeping. Before and after aromatherapy, the mean Pittsburgh Sleep Quality Index score of the nursing home residents was (Equation is included in full-text article.)= 6.0 ± 5.1 and (Equation is included in full-text article.)= 2.6 ± 3.4, respectively, whereas statistically significant difference was not observed for independent variables. Cronbach α reliability coefficient of the Pittsburgh Sleep Quality Index scale was found to be 0.816. The results indicated an improvement of sleep quality of nursing home residents after the application of aromatherapy with lavender oil.

Full Text Available Hearing evaluation usually includes hearing threshold assessment, middle ear function, and word recognition tests that lead to an accurate result of peripheral and central auditory system. However, they have some limitations because they cannot fully encompass all aspects of hearing loss problems. Using self-assessment approach, via a questionnaire or telephone survey, is one of the easiest methods to study hearing loss in population. In this research, 60 nursing home residents (27 females and 33 males ranging from 55 to 85 years with a mean age of were studied via completing self-assessment questionnaire by the elderly cases (NHHI self-version and the other one was filled by the nursing home personnel (NHHI staff-version. The effects of the hearing loss level on the self- and staff-version scores indicated that there is a significant relationship between self- and staff-version with hearing loss levels ( in male and female. Results from this study demonstrate the usefulness of NHHI questionnaire for evaluating hearing handicap of aged people and it may be a useful adjunct in setting up treatment and determining proper care.

We analyze the dependence of galaxy structure (size and Sersic index) and mode of star formation ({Sigma}{sub SFR} and SFR{sub IR}/SFR{sub UV}) on the position of galaxies in the star formation rate (SFR) versus mass diagram. Our sample comprises roughly 640,000 galaxies at z {approx} 0.1, 130,000 galaxies at z {approx} 1, and 36,000 galaxies at z {approx} 2. Structural measurements for all but the z {approx} 0.1 galaxies are based on Hubble Space Telescope imaging, and SFRs are derived using a Herschel-calibrated ladder of SFR indicators. We find that a correlation between the structure and stellar population of galaxies (i.e., a 'Hubble sequence') is already in place since at least z {approx} 2.5. At all epochs, typical star-forming galaxies on the main sequence are well approximated by exponential disks, while the profiles of quiescent galaxies are better described by de Vaucouleurs profiles. In the upper envelope of the main sequence, the relation between the SFR and Sersic index reverses, suggesting a rapid buildup of the central mass concentration in these starbursting outliers. We observe quiescent, moderately and highly star-forming systems to co-exist over an order of magnitude or more in stellar mass. At each mass and redshift, galaxies on the main sequence have the largest size. The rate of size growth correlates with specific SFR, and so does {Sigma}{sub SFR} at each redshift. A simple model using an empirically determined star formation law and metallicity scaling, in combination with an assumed geometry for dust and stars, is able to relate the observed {Sigma}{sub SFR} and SFR{sub IR}/SFR{sub UV}, provided a more patchy dust geometry is assumed for high-redshift galaxies.

To determine the impact of general and oral health status of nursing home residents in Germany on efficacy and acceptance of professional dental cleaning performed by a dental nurse. Participants (N = 41; mean age 83 ± 8 years) living in a nursing home were included. Personal and general health, oral health, oral hygiene habits, and needs were investigated. Individual acceptance regarding professional dental cleaning via different devices (scaler, interdental brushes, ultrasonic cleaning) was assessed, as was the efficacy of this method using after-cleaning indices. Oral health among nursing home residents was impaired and independent from dementia status. Most residents (33/41) performed oral hygiene procedures independently and showed better index values than those in need of external help. Residents requiring help with oral hygiene showed increased risk profiles (higher age, more often immobile, demented, more xerostomia). The dental cleaning procedure required a mean time of 37 ± 11 min, was widely accepted (36/41), and achieved clean results (plaque index 0.1 ± 0.5, oral hygiene index 0.2 ± 1.6, Volpe-Manhold index 0.4 ± 1.6); food residues were reduced to 0 independent from cognitive status. Regarding the cleaning methods, scalers were accepted best without difference between demented and non-demented residents. Professional dental cleaning in nursing homes is an accepted and efficacious oral hygiene procedure among nursing home residents. Professional dental cleaning is an efficacious and accepted method as a first step in line with strategies to improve oral health and should be considered in nursing home residents.

A Body Shape Index (ABSI) and normalized hip circumference (Hip Index, HI) have been recently shown to be strong risk factors for mortality and for cardiovascular disease in adults. We conducted an observational cross-sectional study to evaluate the relationship between ABSI, HI and cardiometabolic risk factors and obesity-related comorbidities in overweight and obese children and adolescents aged 2-18 years. We performed multivariate linear and logistic regression analyses with BMI, ABSI, and HI age and sex normalized z scores as predictors to examine the association with cardiometabolic risk markers (systolic and diastolic blood pressure, fasting glucose and insulin, total cholesterol and its components, transaminases, fat mass % detected by bioelectrical impedance analysis) and obesity-related conditions (including hepatic steatosis and metabolic syndrome). We recruited 217 patients (114 males), mean age 11.3 years. Multivariate linear regression showed a significant association of ABSI z score with 10 out of 15 risk markers expressed as continuous variables, while BMI z score showed a significant correlation with 9 and HI only with 1. In multivariate logistic regression to predict occurrence of obesity-related conditions and above-threshold values of risk factors, BMI z score was significantly correlated to 7 out of 12, ABSI to 5, and HI to 1. Overall, ABSI is an independent anthropometric index that was significantly associated with cardiometabolic risk markers in a pediatric population affected by overweight and obesity.

Optimization of the Refractive-Index Distribution of Graded-Index Polymer Optical Fiber by the Diffusion-Assisted Fabrication Process

Science.gov (United States)

Mukawa, Yoshiki; Kondo, Atsushi; Koike, Yasuhiro

2012-04-01

Graded-index polymer optical fiber (GI-POF) is a promising high-speed communication medium for very-short-reach networks, such as home or office networks. The refractive-index distribution of GI-POF needs to be accurately controlled to maximize the bandwidth. We attempted to control the refractive-index distribution by developing a simulation for dopant diffusion. In the rod-in-tube method, GI-POF with an optimal refractive-index distribution was obtained by adjusting the diffusion temperature and the diffusion time, whereas in the coextrusion process, GI-POF with an optimal refractive-index distribution was fabricated by controlling the length of the diffusion tube and the rate of discharge of polymer.

Informed and engaged parents and healthful home environments are essential for the health of youth. Although research has shown health benefits associated with family meals, to date, no randomized controlled trial (RCT) has been developed to examine the impact of a family meals intervention on behavioral and health outcomes. The Healthy Home Offerings via the Mealtime Environment (HOME) Plus study is a two-arm (intervention versus attention-only control) RCT being conducted in Minneapolis/St. Paul. Built on previous pilot research, HOME Plus aims to increase the frequency and healthfulness of family meals and snacks and reduce children's sedentary behavior, particularly screen time, to promote healthier eating and activity behaviors and prevent obesity. HOME Plus is delivered to families in community settings. The program includes 10 monthly sessions focused on nutrition and activity education, meal planning and preparation skill development. In addition, five motivational goal-setting phone calls are conducted with parents. The primary outcome measure is age- and gender-adjusted child BMI-z score at post-intervention by treatment group. Secondary household-level outcomes include family meal frequency, home availability of healthful foods (fruits/vegetables) and unhealthful foods (high-fat/sugary snacks) and beverages (sugar-sweetened beverages), and the quality of foods served at meals and snacks. Secondary child outcomes include dietary intake of corresponding foods and beverages and screen time. The HOME Plus RCT actively engages whole families of 8-12 year old children to promote healthier eating and activity behaviors and prevent obesity through promotion of family meals and snacks and limited media use.

To examine the potential impact of paraprofessional home visitors in promoting breastfeeding initiation and continuation among a high-risk population. A secondary analysis of program data from a statewide home visitation program. Thirty-six Healthy Families New York sites across New York State. A total of 3521 pregnant mothers at risk of poor child health and developmental outcomes. Home visitors deliver a multifaceted intervention that includes educating high-risk mothers on benefits of breastfeeding, encouraging them to breastfeed and supporting their efforts during prenatal and postnatal periods. Home visitor-reported content and frequency of home visits, participant-reported breastfeeding initiation and duration, and covariates (Kempe Family Stress Index, race and ethnicity, region, nativity, marital status, age, and education). Logistic regression. Breastfeeding initiation increased by 1.5% for each 1-point increase in the percentage of prenatal home visits that included breastfeeding discussions. Breastfeeding continuation during the first 6 months also increased with the percentage of earlier home visits that included breastfeeding discussions. Additionally, if a participant receives 1 more home visit during the third month, her likelihood of breastfeeding at 6 months increases by 11%. Effect sizes varied by months postpartum. Delivering a breastfeeding message consistently during regular home visits is important for increasing breastfeeding rates. Given that home visiting programs target new mothers least likely to breastfeed, a more consistent focus on breastfeeding in this supportive context may reduce breastfeeding disparities.

To determine whether an enhanced occupational therapy discharge planning intervention that involved pre- and postdischarge home visits, goal setting, and follow-up (the HOME program) would be superior to a usual care intervention in which an occupational therapy in-hospital consultation for planning and supporting discharge to home is provided to individuals receiving acute care. Randomized controlled trial. Acute and medical wards. Individuals aged 70 and older (N = 400). Primary outcomes: activities daily living (ADLs; Nottingham Extended Activities of Daily Living) and participation in life roles and activities (Late Life Disability Index (LLDI)). Occupational therapist recommendations differed significantly between groups (P occupational therapy recommendations as the in-hospital only consultation, which had a greater emphasis on equipment provision, but HOME did not demonstrate greater benefit in global measures of ADLs or participation in life tasks than in-hospital consultation alone. It is not recommended that home visits be conducted routinely as part of discharge planning for acutely hospitalized medical patients. Further work should develop guidelines for quality in-hospital consultation. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

The prevalence of home hemodialysis (HHD) in the United States is growing, driven in part by improvements in dialysis machines for home use. We assessed clinical parameters and outcomes in HHD patients using either Fresenius 2008K@home or NxStage System One over 1 year. Patients were 18 years or older and received HHD for ≥30 days between January 1, 2009, and June 30, 2010. A propensity score match was used to control for differences in baseline characteristics, and 2008K@home patients were stratified by frequency of use. Data for outcome measures were analyzed using generalized linear mixed models. Treatment frequency was lower for 2008K@home groups than System One. Mean standardized Kt/V (stdKt/V) was 2.75 for 2008K@home ≥3.5x/week users and 1.99 for System One users (p < 0.001). Erythropoiesis-stimulating agent use tended to be lower for patients using System One. There were no statistically significant differences across groups in serum albumin, calcium, phosphorus, hemoglobin, or parathyroid hormone levels, normalized protein catabolic rate, body mass index, number of hospitalizations, or hospitalized days. Clinical parameters and outcomes for HHD patients using 2008K@home and System One were largely equivalent, although 2008K@home use was associated with higher stdKt/V. Further studies will be required to establish whether these differences in stdKt/V relate to differences in technology, treatment schedule, or a combination thereof.

No systematic reviews and meta-analyses on the use of Z-drug for schizophrenia are available. Randomized, placebo-controlled, or non-pharmacological intervention-controlled trials published before 03/20/2017 were retrieved from major healthcare databases and clinical trial registries. A meta-analysis including only randomized, placebo-controlled trials was performed. Efficacy outcomes were measured as improvement in overall schizophrenia symptoms, total sleep time, and wake after sleep onset. Safety/acceptability outcomes were discontinuation rate and individual adverse events. Four trials [1 alpidem placebo-controlled study (n=66), 2 eszopiclone placebo-controlled studies (n=60), and 1 eszopiclone, shallow needling-controlled study (n=96)] were identified. The meta-analysis showed no significant differences in any outcome between pooled Z-drug and placebo treatment groups. For individual studies, alpidem was superior to placebo in improving the overall schizophrenia symptoms. One of the eszopiclone studies showed that eszopiclone was superior to placebo in improving the Insomnia Severity Index scores. Another eszopiclone study showed that eszopiclone did not differ from shallow needling therapy in improving both schizophrenia- and insomnia-related symptoms. Although this study failed to show significant benefits for the use of Z-drug in the treatment of schizophrenia, it showed that short-term use of eszopiclone is an acceptable method for treating persistent insomnia among these patients.

The purpose of this study was to examine drug use and other factors associated with xerostomia in home care clients aged 75 years or older. The study sample included 270 home care clients aged ≥75 years living in Eastern and Central Finland. The home care clients underwent in-home interviews carried out by trained home care nurses, nutritionists, dental hygienists and pharmacists. The collected data contained information on sociodemographic factors, health and oral health status, drug use, depressive symptoms (GDS-15), cognitive functioning (MMSE), functional ability (Barthel Index, IADL) and nutrition (MNA). The primary outcome was xerostomia status (never, occasionally or continuously). Among the home care clients, 56% (n = 150) suffered from xerostomia. Persons with continuous xerostomia used more drugs and had more depressive symptoms and a higher number of comorbidities than other home care clients. In multivariate analyses, excessive polypharmacy (OR = 1.83, 95% Cl 1.08-3.10) and depressive symptoms (OR = 1.12, 95% Cl 1.03-1.22) were associated with xerostomia. Xerostomia is a common problem among old home care clients. Excessive polypharmacy, use of particular drug groups and depressive symptoms were associated with xerostomia. The findings support the importance of a multidisciplinary approach in the care of older home care clients. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

ZipA binds to FtsZ with high affinity and enhances the stability of FtsZ protofilaments.

Directory of Open Access Journals (Sweden)

Anuradha Kuchibhatla

Full Text Available A bacterial membrane protein ZipA that tethers FtsZ to the membrane is known to promote FtsZ assembly. In this study, the binding of ZipA to FtsZ was monitored using fluorescence spectroscopy. ZipA was found to bind to FtsZ with high affinities at three different (6.0, 6.8 and 8.0 pHs, albeit the binding affinity decreased with increasing pH. Further, thick bundles of FtsZ protofilaments were observed in the presence of ZipA under the pH conditions used in this study indicating that ZipA can promote FtsZ assembly and stabilize FtsZ polymers under unfavorable conditions. Bis-ANS, a hydrophobic probe, decreased the interaction of FtsZ and ZipA indicating that the interaction between FtsZ and ZipA is hydrophobic in nature. ZipA prevented the dilution induced disassembly of FtsZ polymers suggesting that it stabilizes FtsZ protofilaments. Fluorescein isothiocyanate-labeled ZipA was found to be uniformly distributed along the length of the FtsZ protofilaments indicating that ZipA stabilizes FtsZ protofilaments by cross-linking them.

A new strategy based on the host composition design has been adopted to obtain efficient color-tunable emission from Ba2Ln(0.97-z)Tb(z)(BO3)2Cl:0.03Eu (Ln = Y, Gd and Lu, z = 0-0.97) phosphors. This study reveals that the single-phase Ba2Ln(1-z)Tb(z)(BO3)2Cl compounds can be applied to use allowed Eu(2+) absorption transitions to sensitize Eu(3+) emission via the energy transfer Eu(2+) → (Tb(3+))n → Eu(3+). The powder X-ray diffraction (XRD) and Rietveld refinement analysis shows single-phase Ba2Ln(1-z)Tb(z)(BO3)2Cl. As-prepared Ba2Ln(0.97-z)Tb(z)(BO3)2Cl:0.03Eu phosphors show intense green, yellow, orange and red emission under 377 nm near ultraviolet (n-UV) excitation due to a variation in the relative intensities of the Eu(2+), Tb(3+) and Eu(3+) emission depending on the Tb content (z) in the host composition, allowing color tuning. The variation in emission color is explained by energy transfer and has been investigated by photoluminescence and lifetime measurements and is further characterized by the Commission Internationale de l'éclairage (CIE) chromaticity indexes. The quantum efficiencies of the phosphors are high, up to 74%, and show good thermal stabilities up to 150 °C. This investigation demonstrates the possibility to sensitize Eu(3+) line emission by Eu(2+)via energy migration over Tb(3+) resulting in efficient color tunable phosphors which are promising for use in solid-state white light-emitting diodes (w-LEDs).

The goal of this study was to identify home environmental and temperament/behavior variables that best predict standardized reading comprehension scores among school-aged children. Data from 269 children aged 9-16 ( M = 12.08; SD = 1.62) were used in discriminant function analyses to create the Home and Behavior indices. Family income was controlled in each index. The final Home and Behavior models each classified around 75% of cases correctly (reading comprehension at grade level vs. not). Each index was then used to predict other outcomes related to reading. Results showed that Home and/or Behavior accounted for 4-7% of the variance in reading fluency and spelling and 20-35% of the variance in parent-rated problems in math, social anxiety, and other dimensions. These metrics show promise as environmental and temperament/behavior risk scores that could be used to predict and potentially screen for further assessment of reading related problems.

Z' boson mixings with Z-γ and charge assignments

International Nuclear Information System (INIS)

Zhang Ying; Wang Qing

2009-01-01

Based on the general description for Z'-Z-γ mixing as derived from the electroweak chiral Lagrangian, we characterize and classify the various new physics models involving the Z' boson that have appeared in the literature into five classes: 1. Models with minimal Z'-Z mass mixing; 2. Models with minimal Z'-Z kinetic mixing; 3. Models with general Z'-Z mixing; 4. Models with Z'-γ kinetic and Z'-Z mixing; and 5. Models with Stueckelberg-type mixing. The corresponding mixing matrices are explicitly evaluated for each of these classes. We constrain and classify the Z' boson charges with respect to quark-leptons by anomaly cancellation conditions.

Mapping the literature of home health nursing.

Friedman, Yelena

2006-04-01

The purpose of this study was to identify core journals in home health nursing and to determine how well these journals were covered by indexing and abstracting services. The study was part of the project for mapping the nursing literature of the Medical Library Association's Nursing and Allied Health Resource Section. A citation analysis of two core journals was done to determine distribution of references by format types and age of citations and dispersion of the literature, according to Bradford's Law of Scattering. The analysis of indexing coverage for Zone 1 and 2 was also provided. The study showed that 64.2% of citations came from journals, versus 22.9% from books and 12.9% from other publications. PubMed/ MEDLINE rated highest in average indexing coverage of Zone 1 and 2 journals, followed by CINAHL. PsycINFO, SocioAbstracts, and EBSCO Health Business FullTEXT showed practically no coverage for the home health nursing literature. As expected, journal articles were found to be the primary source for referencing and books, the secondary source. In regard to bibliographic control, no databases provided full coverage of the journals in the field of home health nursing. PubMed/MEDLINE and CINAHL gave better results in combination, because CINAHL tended to cover more nursing journals, while PubMed/MEDLINE did better with medical titles.

Monitoring plan for borehole logging at 216-Z-1A Tile Field, 216-Z-9 Trench, and 216-Z-12 Crib

This plan describes the fiscal year 1998 vadose monitoring of three inactive, liquid waste disposal facilities associated with the Plutonium Finishing Plant (Z-Plant): the 216-Z-1A Tile Field, the 216-Z-9 Trench, and the 216-Z-12 Crib. Monitoring will consist of spectral gamma ray logging of 21 boreholes. This plan describes the physical characteristics of the facilities, their operational histories, the subsurface geology and known contamination distribution at each facility. The plan then describes the specific monitoring to be done including the boreholes to be logged, the methods of data acquisition, data reduction, and data evaluation, and finally, the quality control, data management and data reporting for this effort. The three liquid waste disposal facilities at the Z Plant were chosen to be monitored because they were identified as containing some of the most significant sources of radioactive contamination in the Hanford vadose zone. Johnson's analysis was based on the relative hazard obtained by combining curie quantities disposed to the facilities with appropriate health risk standards. The basic question to be addressed by this logging activity addresses the configuration of subsurface contamination since it was last measured. Historical data from the 216-Z-1A Tile Field, the 216-Z-9 Trench, and the 216-Z-12 Crib form the baseline for comparisons to answer this question

Terminally ill patients are at high risk of pressure ulcers, which have a negative impact on quality of life. Data about pressure ulcers' prevalence, incidence and associated factors are largely insufficient. To document the point prevalence at admission and the cumulative incidence of pressure ulcers in terminally ill patients admitted to an Italian home palliative care unit, and to analyse the patients' and caregivers' characteristics associated with their occurrence. Retrospective chart review. Patients ( n = 574) with a life expectancy ⩽6 months admitted to a palliative home care service were included in this study. The prevalence and incidence rates were 13.1% and 13.0%, respectively. The logistic regression models showed body mass index ( p 70 and >1 caregiver at home as the dichotomous variables predictors of presenting with a pressure ulcer at time of admission and during home palliative care. The notable pressure ulcers' incidence and prevalence rates suggest the need to include this issue among the main outcomes to pursue during home palliative care. The accuracy of body mass index, Braden Scale and Karnofsky Performance Scale in predicting the pressure ulcers risk is confirmed. Therefore, they appear as essential tools, in combination with nurses' clinical judgment, for a structured approach to pressure ulcers prevention. Further research is needed to explore the home caregivers' characteristics and attitudes associated with the occurrence of pressure ulcers and the relations between their strategies for pressure ulcer prevention and gender-related patient's needs.

Research indicates that living in neighborhoods with high concentrations of boarded-up vacant homes is associated with premature mortality due to cancer and diabetes, but the mechanism for this relationship is unclear. Boarded-up housing may indirectly impact residents' health by affecting their food environment. We evaluated the association between changes in vacancy rates and changes in the density of unhealthy food outlets as a proportion of all food outlets, termed the food swamp index, in Baltimore, MD (USA) from 2001 to 2012, using neighborhood fixed-effects linear regression models. Over the study period, the average food swamp index increased from 93.5 to 95.3 percentage points across all neighborhoods. Among non-African American neighborhoods, increases in the vacancy rate were associated with statistically significant decreases in the food swamp index (b = -0.38; 90% CI, -0.64 to -0.12; p -value: 0.015), after accounting for changes in neighborhood SES, racial diversity, and population size. A positive association was found among low-SES neighborhoods (b = 0.15; 90% CI, 0.037 to 0.27; p -value: 0.031). Vacant homes may influence the composition of food outlets in urban neighborhoods. Future research should further elucidate the mechanisms by which more distal, contextual factors, such as boarded-up vacant homes, may affect food choices and diet-related health outcomes.

Z-scan is a simple experimental technique to measure intensity dependent nonlinear susceptibilities of third-order nonlinear optical materials. This technique is used to measure the sign and magnitude of both real and imaginary part of the third order nonlinear susceptibility (χ{sup (3)}) of nonlinear optical materials. In this paper, we investigate third-order nonlinear optical properties of Ag-polymer composite film by using single beam z-scan technique with Q-switched, frequency doubled Nd: YAG laser (λ=532 nm) at 5 ns pulse. The values of nonlinear absorption coefficient (β), nonlinear refractive index (n{sub 2}) and third-order nonlinear optical susceptibility (χ{sup (3)}) of permethylazine were found to be 9.64 × 10{sup −7} cm/W, 8.55 × 10{sup −12} cm{sup 2}/W and 5.48 × 10{sup −10} esu, respectively.

Parents' food parenting practices influence children's dietary intake and risk for obesity and chronic disease. Understanding the influence and interactions between parents' practices and children's behavior is limited by a lack of development and psychometric testing and/or limited scope of current measures. The Home Self-Administered Tool for Environmental Assessment of Activity and Diet (HomeSTEAD) was created to address this gap. This article describes development and psychometric testing of the HomeSTEAD family food practices survey. Between August 2010 and May 2011, a convenience sample of 129 parents of children aged 3 to 12 years were recruited from central North Carolina and completed the self-administered HomeSTEAD survey on three occasions during a 12- to 18-day window. Demographic characteristics and child diet were assessed at Time 1. Child height and weight were measured during the in-home observations (following Time 1 survey). Exploratory factor analysis with Time 1 data was used to identify potential scales. Scales with more than three items were examined for scale reduction. Following this, mean scores were calculated at each time point. Construct validity was assessed by examining Spearman rank correlations between mean scores (Time 1) and children's diet (fruits and vegetables, sugar-sweetened beverages, snacks, sweets) and body mass index (BMI) z scores. Repeated measures analysis of variance was used to examine differences in mean scores between time points, and single-measure intraclass correlations were calculated to examine test-retest reliability between time points. Exploratory factor analysis identified 24 factors and retained 124 items; however, scale reduction narrowed items to 86. The final instrument captures five coercive control practices (16 items), seven autonomy support practices (24 items), and 12 structure practices (46 items). All scales demonstrated good internal reliability (α>.62), 18 factors demonstrated construct

Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a view into both the extremely distant and intrinsically faint galaxy populations. We present here some of the most brightly lensed z>6 galaxy candidates known from the Reionization Lensing Cluster Survey (RELICS) and the discovery of a particularly fortuitous z~10 galaxy candidate which has been arced by the effects of strong gravitational lensing. The z~10 candidate has a lensed H-band magnitude of 25.8 AB mag and a high lensing magnification (~4-7). The inferred upper limits on the stellar mass (log [M_star /M_Sun]=9.5) and star formation rate (log [SFR/(M_Sun/yr)]=1.5) indicate that this candidate is a typical star-forming galaxy on the z>6 SFR-M_star relation. We rule out the only low-z solution as unphysical based on the required stellar mass, dust attenuation, size, and [OIII] EW needed for a z~2 SED to match the data. Finally, we reconstruct the source-plane image and estimate the candidate's physical size at z~10, finding a half-light radius of r_e 9 candidates. While the James Webb Space Telescope will detect z>10 with ease, this rare candidate offers the potential for unprecedented spatial resolution less than 500 Myr after the Big Bang.

Breeding common bean populations for traits using selection index

2015-02-01

Full Text Available A common bean (Phaseolus vulgarisL. cultivar must combine desirable genotypes for several traits in order to be accepted by producers and consumers. This study aimed to evaluate selection efficiency when segregating bean populations for traits, by means of a selection index, in order to obtain superior progenies for traits considered. A total of 16 populations from the F4 and F5generations were evaluated in 2011 and 2012, respectively. The traits evaluated were plant architecture, plant disease, grain type and yield. Using standard scores (Z, the sum of the four traits (∑Z was obtained and, based on this information, the best populations were identified. The evaluation of selection effectiveness was performed on 31 progenies from each population. The 496 progenies plus eight controls were evaluated in the F5:6and F5:7 generations for the same traits in July and November 2012, respectively. The selection, using the index based on the sum of standardized variables (∑Z, was efficient for identifying populations with superior progenies for all the traits considered.

On the other hand Future development of elderly care institution is inevitable. Therefore, more attention to the living conditions of elderly residents of institutions seems necessary.

Detection of a new Z' in the Z' → W+W- mode at the SSC

International Nuclear Information System (INIS)

Deshpande, N.G.; Gunion, J.F.; Zwirner, F.

1987-07-01

If a new Z' exists with mass in the TeV region, the decay rate for the mode Z' → W + W - is expected to be of the same order as the ones for Z' → e + e - or Z' → μ + μ - . This mode can be detectable at the SSC via the secondary decays WW → (jet jet)(l nu), (l = e,μ). We compare the expected signal with the backgrounds coming from continuum WW production and W jet jet production in the standard model. Using for this decay selection criteria analogous to the ones proposed for the corresponding decay of a heavy Higgs, we conclude that the signal/background ratio should be considerably larger in the Z' case. This is primarily because, for masses in the TeV range, the Z' width is very much smaller than the Higgs width

Parenting practices toward food and children's behavior: Eating away from home versus at home.

Kasparian, Michelle; Mann, Georgianna; Serrano, Elena L; Farris, Alisha R

2017-07-01

Parenting style influences a child's overall diet quality and establishes food preferences. Parenting style and "food rules" for children differ by eating at home or away from home. Eating meals away from home is increasing despite associations with consumption of unhealthy foods and higher weight status. The objective of the current study was to compare parenting practices and decision-making at restaurants versus at home. A mixed methods approach was utilized: facilitated, individual interviews to explore decision-making and parenting practices; written questionnaires for socio-demographic information; and body mass index. Summaries and emergent themes were generated based on examination of tapes and transcripts. Descriptive statistics were computed for questionnaire data. Twenty-five mothers of children of five to eight years who ate at restaurants at least two times per week participated. Mothers reported more permissive food rules at restaurants yet maintained higher behavioral expectations. Mothers were also more likely to make decisions about whether they eat out, where to eat, and children's meal selections than their children. The findings suggest that parenting practices toward overall behavior and food choices may differ at restaurants than at home, highlighting the importance of healthy menu options, further research, and educational strategies.

Home-based renal replacement therapy (RRT) [peritoneal dialysis (PD) and home hemodialysis (HHD)] offers independent quality of life and clinical advantages compared to conventional in-center hemodialysis. However, follow-up may be less complete for home dialysis patients following a change in care settings such as post hospitalization. We aim to implement a Home Dialysis Virtual Ward (HDVW) strategy, which is targeted to minimize gaps of care. The HDVW Pilot Study will enroll consecutive PD and HHD patients who fulfilled any one of our inclusion criteria: 1. following discharge from hospital, 2. after interventional procedure(s), 3. prescription of anti-microbial agents, or 4. following completion of home dialysis training. Clinician-led telephone interviews are performed weekly for 2 weeks until VW discharge. Case-mix (modified Charlson Comorbidity Index), symptoms (the modified Edmonton Symptom Assessment Scale) and patient satisfaction are assessed serially. The number of VW interventions relating to eight pre-specified domains will be measured. Adverse events such as re-hospitalization and health-services utilization will be ascertained through telephone follow-up after discharge from the VW at 2, 4, 12 weeks. The VW re-hospitalization rate will be compared with a contemporary cohort (matched for age, gender, renal replacement therapy and co-morbidities). Our protocol has been approved by research ethics board (UHN: 12-5397-AE). Written informed consent for participation in the study will be obtained from participants. This report serves as a blueprint for the design and implementation of a novel health service delivery model for home dialysis patients. The major goal of the HDVW initiative is to provide appropriate and effective supports to medically complex patients in a targeted window of vulnerability. (NCT01912001).

Home parenteral nutrition has become routine for management of intestinal failure in patients. In Poland the main obstacle to widespread use of home parenteral nutrition is the lack of interest of commercial companies in delivering feedings and ancillaries to patients. Twenty-five home parenteral nutrition patients aged from 4 months to more than 13 years were reviewed. The mother or both parents were trained in home parenteral nutrition techniques for 4 to 6 weeks and compounded the nutrients themselves at home. The mean duration of home parenteral nutrition was 10,117 patient days. Hospital stays of patients receiving parenteral feedings were significantly shorter than the duration of administration of home parenteral nutrition (p rate of catheter occlusion decreased within the observation period, and in 1997 not one case of occlusion was observed. In 1997 only three catheters were removed during 7.8 patient years, and the overall incidence of catheter-related complications was 0.38 per patient year. The overall occurrence of septicemia was one case in 516 days and of catheter infection was one in 459 days. In 1997 a catheter was infected on average of once every 1419 days. There was significant improvement in the z score for weight during therapy. The average monthly cost of nutrients and ancillary items was approximately $1200 (4200 Polish zlotys [PLN]). These costs are 1.6 to 3 times lower than those recorded in other studies. Home parenteral nutrition in children with nutrients mixed by caregivers in the home setting is a safe and appropriate method of treatment that can be used in countries where home parenteral nutrition solutions are not manufactured or where commercial home parenteral nutrition is not economically feasible.

Differences in distribution of T-scores and Z-scores among bone densitometry tests in postmenopausal women (a comparative study)

International Nuclear Information System (INIS)

Wendlova, J.

2002-01-01

To determine the character of T-score and Z-score value distribution in individually selected methods of bone densitometry and to compare them using statistical analysis. We examined 56 postmenopausal women with an age between 43 and 68 years with osteopenia or osteoporosis according to the WHO classification. The following measurements were made in each patient: T-score and Z-score for: 1) Stiffness index (S) of the left heel bone, USM (index). 2) Bone mineral density of the left heel bone (BMDh), DEXA (g of Ca hydroxyapatite per cm 2 ). 3) Bone mineral density of trabecular bone of the L1 vertebra (BMDL1). QCT (mg of Ca hydroxyapatite per cm 3 ). The densitometers used in the study were: ultrasonometer to measure heel bone, Achilles plus LUNAR, USA: DEXA to measure heel bone, PIXl, LUNAR, USA: QCT to measure the L1 vertebra, CT, SOMATOM Plus, Siemens, Germany. Statistical analysis: differences between measured values of T-scores (Z-scores) were evaluated by parametric or non-parametric methods of determining the 95 % confidence intervals (C.I.). Differences between Z-score and T-score values for compared measurements were statistically significant; however, these differences were lower for Z-scores. Largest differences in 95 % C.I., characterizing individual measurements of T-score values (in comparison with Z-scores), were found for those densitometers whose age range of the reference groups of young adults differed the most, and conversely, the smallest differences in T-score values were found when the differences between the age ranges of reference groups were smallest. The higher variation in T-score values in comparison to Z-scores is also caused by a non-standard selection of the reference groups of young adults for the QCT, PIXI and Achilles Plus densitometers used in the study. Age characteristics of the reference group for T-scores should be standardized for all types of densitometers. (author)

Lahmann, Nils A; Tannen, Antje; Suhr, Ralf

2016-10-01

This study aimed to provide representative figures about the prevalence of underweight and malnutrition among home care clients, and to determine the associated risk factors and the provided nutritional nursing interventions. In 2012, a multicenter point prevalence study was conducted among 878 randomly selected clients from 100 randomly selected home care services across Germany. Following a standardized study protocol, demographics, nutritional assessments (Body Mass Index, Malnutrition Universal Screening Tool (MUST), Mini nutritional Assessment - short form (MNA-sf), nurses' clinical judgment on nutritional status) and interventions were assessed. Common nutritional risk factors for underweight and malnutrition were analyzed in a logistic regression model. Malnutrition figures varied between 4.8% (MNA-sf) and 6.8% (MUST), underweight between 8.7% (BMI malnutrition assessments (MNA-sf 48.8%, MUST 39.1%) due to a lack of information on many clients' loss of weight within the past 3-6 months. Regular weighing was performed in 33.6-57.3% of all clients, depending on weight and nutritional status. Mental overload (OR 8.1/4.4), needs help with feeding (OR 5.0/2.8) and loss of appetite (OR 3.6/3.9) were highly associated with malnutrition/underweight. Malnutrition and underweight are important issues in home care clients. Regular weighing should be performed in all home care clients so that a potential weight loss can be detected in time.

Study of the di-nuclear system $^{A}$Rb + $^{209}$Bi (Z$_{1}$ + Z$_{2}$ = 120)

CERN Multimedia

The exact location of the next spherical shell closures beyond Z = 82, N = 126 is still an open question. According to model predictions shell closures are expected at Z = 114 or 120 or 126 and N = 184. Also experimental data cannot yet give a definite answer. Known nuclei with Z = 114 are too neutron‐deficient with respect to the N = 184 shell and nuclei with Z = 120 and beyond are still unknown. An option for studying reactions of super-heavy systems at Z = 120 and neutron numbers up to 184 becomes possible with the use of $^{209}$Bi targets and neutron‐rich beams. By studying quasi-fission and fusion‐fission reactions, which have significantly larger production cross‐sections than the evaporation residues, a possible influence of shell closures at Z = 120, N = 184 can be explored. Well suitable for such studies will be neutron‐rich rubidium beams at energies of about 5 MeV/u delivered by the HIE‐ISOLDE facility.

Background/Aims The post-reflux swallow-induced peristaltic wave (PSPW) index and esophageal baseline impedance (BI) are novel impedance parameters used to evaluate esophageal chemical clearance and mucosal integrity. However, their relationship with reflux symptoms is not known. We aim to evaluate the correlations of PSPW index and esophageal BI with gastroesophageal reflux disease (GERD) symptoms. Methods We performed a retrospective review of multichannel intraluminal impedance and pH (MII-pH) tracings in patients with suspected GERD. Reflux symptoms were also analyzed from checklists using ordinal scales. The PSPW index and esophageal BIs in 6 spots (z1–z6) were measured. Bivariate (Spearman) correlation was used to analyze the relationship between the PSPW index or esophageal BI, and the degree of GERD symptoms measured. Results The MII-pH records of 143 patients were analyzed. The PSPW index was significantly lower in patients who had heartburn and negatively correlated with the degree of heartburn (r = −0.186, P < 0.05). On the contrary, the PSPW index was not significantly correlated with the degree of dysphagia (r = −0.013, P = 0.874). Distal esophageal BI was not significantly correlated with heartburn, but negatively correlated with the degree of dysphagia (z3: r = −0.328, z4: r = −0.361, z5: r = −0.316, z6: r = −0.273; P < 0.05). Conclusions These findings suggest that delayed chemical clearance of the esophagus may induce heartburn, but that it is not related to dysphagia. However, a lack of esophageal mucosal integrity may be related to dysphagia. PMID:28044052

Full Text Available Introduction: Pilonidal sinus is one of the common problems encountered in general surgical practices and the management of this disease is variable, contentious and problematic. Principles of treatment require eradication of the sinus tract; complete healing and prevention of recurrence. Although several surgical techniques have been described over the years, the management remains controversial. Aims and Objectives: The aim of this study was to compare the two techniques of the open method and Z-plasty in the management of pilonidal sinus, in terms of incidence of post-operative pain, total hospital stay, total recovery time, complications and recurrence rate. Materials and Methods: This is a prospective comparative study which was conducted in the surgical department of a teaching hospital. A total of 50 cases were included in this study. Of these, 25 cases were operated by the open technique and 25 by excision and Z-plasty. Observation and Result: The mean age at presentation was 29.44 years. Male genders followed by age between 20 and 30 years were the most common predisposing factors. The mean body mass index, early and late post-operative complications were comparable between the two groups. Mean hospital stay and total recovery time was significantly more in open technique group compared with Z-plasty group. Visual analog score was also significantly more in open technique group when compared with Z-plasty group. Conclusion: Excision with Z-plasty was better technique in terms of lesser hospital stay, lesser recovery time, less post-operative pain.

Summary Background Visualization can reduce the cognitive load of information, allowing users to easily interpret and assess large amounts of data. The purpose of our study was to examine home health data using visual analysis techniques to discover clinically salient associations between patient characteristics with problem-oriented health outcomes of older adult home health patients during the home health service period. Methods Knowledge, Behavior and Status ratings at discharge as well as change from admission to discharge that was coded using the Omaha System was collected from a dataset on 988 de-identified patient data from 15 home health agencies. SPSS Visualization Designer v1.0 was used to visually analyze patterns between independent and outcome variables using heat maps and histograms. Visualizations suggesting clinical salience were tested for significance using correlation analysis. Results The mean age of the patients was 80 years, with the majority female (66%). Of the 150 visualizations, 69 potentially meaningful patterns were statistically evaluated through bivariate associations, revealing 21 significant associations. Further, 14 associations between episode length and Charlson co-morbidity index mainly with urinary related diagnoses and problems remained significant after adjustment analyses. Through visual analysis, the adverse association of the longer home health episode length and higher Charlson co-morbidity index with behavior or status outcomes for patients with impaired urinary function was revealed. Conclusions We have demonstrated the use of visual analysis to discover novel patterns that described high-needs subgroups among the older home health patient population. The effective presentation of these data patterns can allow clinicians to identify areas of patient improvement, and time periods that are most effective for implementing home health interventions to improve patient outcomes.

Stroke and Nursing Home care: a national survey of nursing homes.

LENUS (Irish Health Repository)

Cowman, Seamus

2010-01-01

BACKGROUND: Although stroke is recognised as a major factor in admission to nursing home care, data is lacking on the extent and nature of the disabilities and dependency in nursing homes arising from stroke. A national study conducted in nursing homes can quantify the number of residents with stroke in nursing homes, their disability and levels of dependency. METHODS: A cross-sectional survey research design was used. A total of 572 public and private nursing homes were identified nationally and a stratified random selection of 60 nursing homes with 3,239 residents was made. In half of the nursing homes (n = 30) efforts were made to interview all residents with stroke Survey instruments were used to collect data from residents with stroke and nursing home managers on demography, patient disability, and treatment. RESULTS: Across all nursing homes (n = 60), 18% (n = 570) of the residents had previously had a stroke. In homes (n = 30), where interviews with residents with stroke (n = 257), only 7% (n = 18) residents were capable of answering for themselves and were interviewed. Data on the remaining 93% (n = 239) residents were provided by the nursing home manager. Nurse Managers reported that 73% of residents with stroke had a high level of dependency. One in two residents with stroke was prescribed antidepressants or sedative medication. Only 21% of stroke residents were prescribed anticoagulants, 42% antiplatelets, and 36% cholesterol lowering medications. Stroke rehabilitation guidelines were lacking and 68% reported that there was no formal review process in place. CONCLUSIONS: This study provides seminal findings on stroke and nursing home services in Ireland. We now know that one in six nursing home residents in a national survey are residents with a stroke, and have a wide range of disabilities. There is currently little or no structured care (beyond generic care) for stroke survivors who reside in nursing homes in Ireland.

Accurate Bessel functions Jsub(n)(z), Ysub(n)(z), Hsub(n)sup((1))(z) and Hsub(n)sup((2))(z) of integer order and complex argument

The Bessel function appears in a wide range of physical applications, and in particular where there is axial symmetry. The package contains complex function routines to calculate Jsub(n)(z), Ysub(n)(z), Hsub(n)sup((1))(z) and Hsub(n)sup((2))(z) for integer n and complex z. The method of solution is based on the ascending series representations and asymptotic forms of the Bessel functions Jsub(n)(z) and Ysub(n)(z) and asymptotic forms of the modified Bessel functions Isub(n)(z) and Ksub(n)(z). The program will return results for all values of mod(z) up to machine overflows in the Bessel functions. The size of the order should not be too large (say, mod(n) -11 . For the asymptotic region, the accuracy EPS may not always be achieved (since the asymptotic series may have to be truncated at their lower terms), in which case the output parameter ISET will indicate this and an estimation of the relative error is also produced. The functions Ysub(n)(z), Hsub(n)sup((1))(z) and Hsub(n)sup((2))(z) have a branch point at the origin, together with a cut along the negative real axis. (Auth.)

Specific immunochemical probes for Z-RNA were generated and characterized to search for possible Z-RNA-like double helices in cells. Z-RNA was detected in the cytoplasm of fixed protozoan cells by immunofluorescence microscopy using these anti-Z-RNA IgCs. In contrast, autoimmune or experimentally elicited anti-DNA antibodies, specifically reactive with B-DNA or Z-DNA, stained the nuclei. Pre-or nonimmune IgGs did not bind to the cells. RNase A or T1 digestion eliminated anti-Z-RNA IgG binding to cytoplasmic determinants; however, DNase I or mung bean nuclease had no effect. Doxorubicin and ethidium bromide prevented anti-Z-RNA antibody binding; however, actinomycin D, which does not bind double-stranded RNA, did not. Anti-Z-RNA immunofluorescence was specifically blocked in competition assays by synthetic Z-RNA but not Z-DNA, A-RNA, or single-stranded RNAs. Thus, some cytoplasmic sequences in fixed cells exist in the left-handed Z-RNA conformation

We used Home Mortgage Disclosure Act (HMDA) data to demonstrate a method for constructing a residential redlining index to measure institutional racism at the community level. We examined the application of the index to understand the social context of health inequities by applying the residential redlining index among a cohort of pregnant women in Philadelphia. We used HMDA data from 1999-2004 to create residential redlining indices for each census tract in Philadelphia County, Pennsylvania. We linked the redlining indices to data from a pregnancy cohort study and the 2000 Census. We spatially mapped the levels of redlining for each census tract for this pregnancy cohort and tested the association between residential redlining and other community-level measures of segregation and individual health. From 1999-2004, loan applicants in Philadelphia County, Pennsylvania, of black race/ethnicity were almost two times as likely to be denied a mortgage loan compared with applicants who were white (e.g., 1999 odds ratio [OR] = 2.00, 95% confidence interval [CI] 1.63, 2.28; and 2004 OR=2.26, 95% CI 1.98, 2.58). The majority (77.5%) of the pregnancy cohort resided in redlined neighborhoods, and there were significant differences in residence in redlined areas by race/ethnicity (pracism may contribute to our understanding of health disparities. Residential redlining and mortgage discrimination against communities may be a major factor influencing neighborhood structure, composition, development, and wealth attainment. This residential redlining index as a measure for institutional racism can be applied in health research to understand the unique social and neighborhood contexts that contribute to health inequities.

Full Text Available Abstract Background This study aims to describe the development, testing and optimization of a new standard instrument, the Consumer Quality Index (CQ-index® Long-term Care, for measuring client experiences with long-term care in the Netherlands. Methods Three versions of the CQ-index questionnaires and protocols for study sampling and data collection were developed, designed for interviews with residents of nursing or residential care homes and postal surveys among representatives of psychogeriatric residents and homecare clients. From July to November 2006 a pilot study was conducted among 2,697 clients of 68 nursing or residential care homes, 2,164 representatives of clients in 57 psychogeriatric care institutions, and 1,462 clients of 19 homecare organizations. We performed psychometric analyses and descriptive analyses, and evaluated the pilot study. Results The pilot study showed the feasibility and usability of the instruments, supported the multidimensionality of the questionnaires and showed first findings on client experiences and possibilities for quality improvement. Nine scales applied to all care settings: shared decision making, attitude and courtesy, information, body care, competence and safety of care, activities, autonomy, mental well-being, and availability of personnel. The pilot resulted in three optimized questionnaires and recommendations for nationwide implementation. Conclusions The CQ-index® Long-term Care provides a good basis to investigate the quality of nursing homes, residential care homes and homecare from the clients' perspective. This standardized instrument enables a nationwide comparison of the quality of long-term care for the purpose of transparency and quality assurance.

Convention defines pediatric adiposity by the body mass index z-score (BMIz) referenced to normative growth charts. Waist-to-height ratio (WHtR) does not depend on sex-and-age references. In the HEALTHY Study enrollment sample, we compared BMIz with WHtR for ability to identify adverse cardiometabolic risk. Among 5,482 sixth-grade students from 42 middle schools, we estimated explanatory variations (R 2) and standardized beta coefficients of BMIz or WHtR for cardiometabolic risk factors: insulin resistance (HOMA-IR), lipids, blood pressures, and glucose. For each risk outcome variable, we prepared adjusted regression models for four subpopulations stratified by sex and high versus lower fatness. For HOMA-IR, R 2 attributed to BMIz or WHtR was 19%–28% among high-fatness and 8%–13% among lower-fatness students. R 2 for lipid variables was 4%–9% among high-fatness and 2%–7% among lower-fatness students. In the lower-fatness subpopulations, the standardized coefficients for total cholesterol/HDL cholesterol and triglycerides tended to be weaker for BMIz (0.13–0.20) than for WHtR (0.17–0.28). Among high-fatness students, BMIz and WHtR correlated with blood pressures for Hispanics and whites, but not black boys (systolic) or girls (systolic and diastolic). In 11-12 year olds, assessments by WHtR can provide cardiometabolic risk estimates similar to conventional BMIz without requiring reference to a normative growth chart. PMID:25132986

OBJECTIVES: A comprehensive and systematic assessment (HTA) of early home-supported discharge by a multidisciplinary team that plans, coordinates, and delivers care at home (EHSD) was undertaken and the results were compared with that of conventional rehabilitation at stroke units. METHODS......: A systematic literature search for randomized trials (RCTs) on "early supported discharge" was closed in April 2005. RCTs on EHSD without information on (i) death or institution at follow-up, (ii) change in Barthél Index, (iii) length of hospital stay, (iv) intensity of home rehabilitation, or (v) baseline...... are discussed. CONCLUSIONS: EHSD is evidenced as a dominant health intervention. However, financial barriers between municipalities and health authorities have to be overcome. For qualitative reasons, a learning path of implementation is recommended where one stroke unit in a region initiates EHSD...

2010-07-01

Fish-based indices monitor changes in surface waters and are a valuable aid in communication by summarising complex information about the environment (Harrison and Whitfield, 2004). A zone-specific fish-based multimetric estuarine index of biotic integrity (Z-EBI) was developed based on a 13 year time series of fish surveys from the Zeeschelde estuary (Belgium). Sites were pre-classified using indicators of anthropogenic impact. Metrics showing a monotone response with pressure classes were selected for further analysis. Thresholds for the good ecological potential (GEP) were defined from references. A modified trisection was applied for the other thresholds. The Z-EBI is defined by the average of the metric scores calculated over a one year period and translated into an ecological quality ratio (EQR). The indices integrate structural and functional qualities of the estuarine fish communities. The Z-EBI performances were successfully validated for habitat degradation in the various habitat zones.

The aim of the study was to examine the outcomes of transepithelial photorefractive keratectomy (Trans-PRK) and Femtosecond Laser-assisted in situ keratomileusis (Z-LASIK) for the correction of high myopia. A retrospective cohort study design was used. The study group included 792 eyes with high-grade myopia (- 6.0 diopters or higher) or high-grade myopia with astigmatism that were treated with Z-LASIK or Trans-PRK in 2013 through 2014 in an optical outpatient clinic of a large private medical service. The Trans-PRK group comprised of 674 eyes with a spherical equivalent (SE) of - 7.87 ± 1.46 and the Z-LASIK group comprised of 118 eyes with a SE of - 7.19 ± 0.81 (P PRK group was - 0.06 and - 0.02 in the Z-LASIK group (P = 0.545). Efficacy index values were 0.92 in the Trans-PRK group and 0.95 in the Z-LASIK group (P = 0.083), and corresponding safety index values were 0.95 and 0.97 (P = 0.056). An UCVA of 20/40 or better was achieved in 94.20% of eyes in the Trans-PRK group, and 98.31% in the Z-LASIK group (P = 0.063). The majority of eyes in both the Trans-PRK and Z-LASIK groups were within ± 0.5D of attempted correction: 59.35 and 64.71%, respectively (P = 0.271). Both Trans-PRK and Z-LASIK demonstrated excellent efficacy, safety and predictability profiles, with results comparable and in some cases superior to the current literature. Results of Z-LASIK were slightly better than those of Trans-PRK, though the preoperative SE of the latter was higher.

A relation between the index Dsub(st) and azimuthal component Bsub(y) of interplanetary magnetic field (IMF) vector during several magnetic storms with Dsub(st) > 100nT is discussed. It is established that the relation between Dsub(st) index and Bsub(y) and Esub(z) component of electric interplanetary field (EIF) is closed than the relation between Dsub(st) and Bsub(z) component of IMF and Esub(y) component of EIF. Correlation coefficients of Dsub(st) and Bsub(y) and Esub(z) differ but slightly from each other

2001-01-01

Using a new radio sample, 6C* designed to find radio galaxies at z > 4 along with the complete 3CRR and 6CE sample we extend the radio galaxy K-z relation to z~4.5. The 6C* K-z data significantly improve delineation of the K-z relation for radio galaxies at high redshift (z > 2). Accounting for non-stellar contamination, and for correlations between radio luminosity and estimates of stellar mass, we find little support for previous claims that the underlying scatter in the stellar luminosity ...

We investigate the rest-frame UV morphologies of a large sample of Lyman α emitters (LAEs) from z ˜ 2 to z ˜ 6, selected in a uniform way with 16 different narrow and medium bands over the full COSMOS field. We use 3045 LAEs with Hubble Space Telescope coverage in a stacking analysis and find that they have MUV ˜ -20, below M_UV^\\ast at these redshifts. We also focus our analysis on a subsample of 780 individual galaxies with iAB < 25 for which GALFIT converges for 429 of them. The individual median size (re ˜ 1 kpc), ellipticities [slightly elongated with (b/a) ˜ 0.45], Sérsic index (disc-like with n ≲ 2), and light concentration (comparable to that of disc or irregular galaxies, with C ˜ 2.7) of LAEs show mild evolution from z ˜ 2 to z ˜ 6. LAEs with the highest rest-frame equivalent widths (EWs) are the smallest/most compact (re ˜ 0.8 kpc, compared to re ˜ 1.5 kpc for the lower EW LAEs). When stacking our samples in bins of fixed Lyα luminosity and Lyα EW, we find evidence for redshift evolution in n and C, but not in galaxy sizes. The evolution seems to be stronger for LAEs with 25 < EW < 100 Å. When compared to other star-forming galaxies (SFGs), LAEs are found to be smaller at all redshifts. The difference between the two populations changes with redshift, from a factor of ˜1 at z ≳ 5 to SFGs being a factor of ˜2-4 larger than LAEs for z ≲ 2. This means that at the highest redshifts, where typical sizes approach those of LAEs, the fraction of galaxies showing Lyα in emission (and with a high Lyα escape fraction) should be much higher, consistent with observations.

In order to examine the potential of low-Z detector materials for PET, a small field imaging system using plastic detectors has been designed. In this system the site of a photon interaction in the detector is located using light produced by the first Compton electron. This is in contrast to high-Z detectors where multiple interactions occur. The calculated performance of the detector and supporting measurements are presented

Higgs decays to Z Z and Z γ in the standard model effective field theory: An NLO analysis

Science.gov (United States)

Dawson, S.; Giardino, P. P.

2018-05-01

We calculate the complete one-loop electroweak corrections to the inclusive H →Z Z and H →Z γ decays in the dimension-6 extension of the Standard Model Effective Field Theory (SMEFT). The corrections to H →Z Z are computed for on-shell Z bosons and are a precursor to the physical H →Z f f ¯ calculation. We present compact numerical formulas for our results and demonstrate that the logarithmic contributions that result from the renormalization group evolution of the SMEFT coefficients are larger than the finite next-to-leading-order contributions to the decay widths. As a byproduct of our calculation, we obtain the first complete result for the finite corrections to Gμ in the SMEFT.

Medicare home health utilization as a function of nursing home market factors.

Rapid increases in the size and costs of the home health market, unknown impacts of Medicare's DRG hospital reimbursement on the posthospital market, and general lack of knowledge about factors that explain interstate variation in home health utilization all suggest the importance of developing and testing models of Medicare home health use. This article proposes and tests a model of state home health utilization as a function of the nursing home market. This model proposes that home health u...

Cytological profile of antibacterial FtsZ inhibitors and synthetic peptide MciZ

Directory of Open Access Journals (Sweden)

Lidia Araujo-Bazan

2016-10-01

Full Text Available Cell division protein FtsZ is the organizer of the cytokinetic ring in almost all bacteria and a target for the discovery of new antibacterial agents that are needed to counter widespread antibiotic resistance. Bacterial cytological profiling, using quantitative microscopy, is a powerful approach for identifying the mechanism of action of antibacterial molecules affecting different cellular pathways. We have determined the cytological profile on Bacillus subtilis cells of a selection of small molecule inhibitors targeting FtsZ on different binding sites. FtsZ inhibitors lead to long undivided cells, impair the normal assembly of FtsZ into the midcell Z-rings, induce aberrant ring distributions, punctate FtsZ foci, membrane spots and also modify nucleoid length. Quantitative analysis of cell and nucleoid length combined, or the Z-ring distribution, allows categorizing FtsZ inhibitors and to distinguish them from antibiotics with other mechanisms of action, which should be useful for identifying new antibacterial FtsZ inhibitors. Biochemical assays of FtsZ polymerization and GTPase activity combined explain the cellular effects of the FtsZ polymer stabilizing agent PC190723 and its fragments. MciZ is a 40-aminoacid endogenous inhibitor of cell division normally expressed during sporulation in B. subtilis. Using FtsZ cytological profiling we have determined that exogenous synthetic MciZ is an effective inhibitor of B. subtilis cell division, Z-ring formation and localization. This finding supports our cell-based approach to screen for FtsZ inhibitors and opens new possibilities for peptide inhibitors of bacterial cell division.

During preventive home visits, the purpose of this study was to identify the prevalence of fall risk and any associated factors. Participants (n = 1471) were cognitively sound community-dwelling older adults (≥ 70 years) without home-help service, living in a Swedish municipality. The Downton Fall Risk Index and nine single items were used. Tiredness/fatigue, age ≥ 80, inability to walk 1 hr, inability to climb stairs and worrying were significantly associated with fall risk. Preventive home visits incorporating fall-risk screening proved valuable, providing information for interventions aimed at preventing falls, maintaining independence, and facilitating health among community dwelling participants.

Histones are the fundamental constituents of the eukaryotic chromatin, facilitating the physical organization of DNA in chromosomes and participating in the regulation of its metabolism. The H2A family displays the largest number of variants among core histones, including the renowned H2A.X, macroH2A, H2A.B (Bbd), and H2A.Z. This latter variant is especially interesting because of its regulatory role and its differentiation into 2 functionally divergent variants (H2A.Z.1 and H2A.Z.2), further specializing the structure and function of vertebrate chromatin. In the present work we describe, for the first time, the presence of a second H2A.Z variant (H2A.Z.2) in the genome of a non-vertebrate animal, the mussel Mytilus. The molecular and evolutionary characterization of mussel H2A.Z.1 and H2A.Z.2 histones is consistent with their functional specialization, supported on sequence divergence at promoter and coding regions as well as on varying gene expression patterns. More precisely, the expression of H2A.Z.2 transcripts in gonadal tissue and its potential upregulation in response to genotoxic stress might be mirroring the specialization of this variant in DNA repair. Overall, the findings presented in this work complement recent reports describing the widespread presence of other histone variants across eukaryotes, supporting an ancestral origin and conserved role for histone variants in chromatin.

2013-12-01

Full Text Available Background and aims. Bleaching may exert some negative effects on existing composite resin restorations. The aim of this study was to evaluate the effect of home bleaching on microleakage of fiber-reinforced and particle-filled composite resins. Materials and methods. Ninety class V cavities (1.5×2×3 mm were prepared on the buccal surfaces of 90 bovine teeth. The teeth were randomly divided into 6 groups (n=15 and restored as follows: Groups 1 and 2 with Z100, groups 3 and 4 with Z250, and groups 5 and 6 with Nulite F composite resins. All the specimens were thermocycled. Groups 1, 3 and 5 were selected as control groups (without bleaching and the experimental groups 2, 4 and 6 were bleached with 22% carbamide peroxide gel. All the samples were immersed in 2% basic fuchsin dye for 24 hours and then sectioned longitudinally. Dye penetration was evaluated under a stereomicroscope (×25, at both the gingival and incisal margins. Data were analyzed using Kruskal-Wallis, Mann-Whitney and Wilcoxon tests (α=0.05. Results. Statistical analyses revealed that bleaching gel increased microleakage only at gingival margins with Z250 (P=0.007. Moreover, the control groups showed a statistically significant difference in microleakage at their gingival margins. Nulite F had the maximum microleakage while Z250 showed the minimum (P=0.006. Conclusion. Microleakage of home-bleached restorations might be related to the type of composite resin used.

We study the structural evolution of massive galaxies by linking progenitors and descendants at a constant cumulative number density of n c = 1.4 × 10 –4 Mpc –3 to z ∼ 3. Structural parameters were measured by fitting Sérsic profiles to high-resolution CANDELS HST WFC3 J 125 and H 160 imaging in the UKIDSS-UDS at 1 814 imaging in COSMOS at 0.25 c , galaxies grow in stellar mass by a factor of ∼3 from z ∼ 3 to z ∼ 0. The size evolution is complex: galaxies appear roughly constant in size from z ∼ 3 to z ∼ 2 and then grow rapidly to lower redshifts. The evolution in the surface mass density profiles indicates that most of the mass at r e ∝M 2.0 , consistent with scenarios that find dissipationless minor mergers to be a key driver of size evolution. The progenitors at z ∼ 3 were likely star-forming disks with r e ∼ 2 kpc, based on their low Sérsic index of n ∼ 1, low median axis ratio of b/a ∼ 0.52, and typical location in the star-forming region of the U – V versus V – J diagram. By z ∼ 1.5, many of these star-forming disks disappeared, giving rise to compact quiescent galaxies. Toward lower redshifts, these galaxies continued to assemble mass at larger radii and became the local ellipticals that dominate the high-mass end of the mass function at the present epoch.

Nonlinear refractive index measurements and self-action effects in Roselle-Hibiscus Sabdariffa solutions

2006-12-01

We report the observation of self-action phenomena, such as self-focusing, self-defocusing, self-phase modulation and beam fanning in Roselle-Hibiscus Sabdariffa solutions. This material is found to be a new type of natural nonlinear media, and the nonlinear reflective index coefficient has been determined using a Z-scan technique and by measuring the critical power for the self-trapping effect. Z-scan measurements show that this material has a large negative nonlinear refractive index, n 2 = 1 × 10-4 esu. A comparison between the experimental n 2 values and the calculated thermal value for n 2 suggests that the major contribution to nonlinear response is of thermal origin.

The COPD Patient Management European Trial (COMET) investigated the efficacy and safety of a home-based COPD disease management intervention for severe COPD patients.The study was an international open-design clinical trial in COPD patients (forced expiratory volume in 1 s management intervention or to the usual management practices at the study centre. The disease management intervention included a self-management programme, home telemonitoring, care coordination and medical management. The primary end-point was the number of unplanned all-cause hospitalisation days in the intention-to-treat (ITT) population. Secondary end-points included acute care hospitalisation days, BODE (body mass index, airflow obstruction, dyspnoea and exercise) index and exacerbations. Safety end-points included adverse events and deaths.For the 157 (disease management) and 162 (usual management) patients eligible for ITT analyses, all-cause hospitalisation days per year (mean±sd) were 17.4±35.4 and 22.6±41.8, respectively (mean difference -5.3, 95% CI -13.7 to -3.1; p=0.16). The disease management group had fewer per-protocol acute care hospitalisation days per year (p=0.047), a lower BODE index (p=0.01) and a lower mortality rate (1.9% versus 14.2%; pmanagement intervention did not significantly reduce unplanned all-cause hospitalisation days, but reduced acute care hospitalisation days and mortality in severe COPD patients.

Parameterization of general Z-γ-Z' mixing in an electroweak chiral theory

International Nuclear Information System (INIS)

Zhang Ying; Wang Qing

2012-01-01

A new general parameterization with eight mixing parameters among Z, γ and an extra neutral gauge boson Z ' is proposed and subjected to phenomenological analysis. We show that in addition to the conventional Weinberg angle θ W , there are seven other phenomenological parameters, G ' , ξ, η, θ 1 , θ r , r and l, for the most general Z-γ-Z ' mixings, in which parameter G ' arises due to the presence of an extra Stueckelbergtype mass coupling. Combined with the conventional Z-Z ' mass mixing angle 0', the remaining six parameters, ξ, η, θ l -θ ' , θ r - θ ' , r and l, are caused by general kinetic mixing. In all eight phenomenological parameters, θ W , G ' , ξ, η, θ 1 , θ r , r and l, we can determine the Z-Z ' mass mixing angle θ ' and the mass ratio M Z /M Z ' . The Z-γ-Z ' mixing that we discuss are based on the model-independent description of the extended electroweak chiral Lagrangian (EWCL) previously proposed by us. In addition, we show that there are eight corresponding independent theoretical coefficients in our EWCL, which are fully fixed by our eight phenomenological mixing parameters. We further find that the experimental measurability of these eight parameters does not rely on the extended neutral current for Z ' , but depends on the Z-Z ' mass ratio. (authors)

It is often observed that pain causes substantial problems for nursing home residents. However, there has been little research about the prevalence of pain for nursing home residents in Japan. This study aimed to examine the prevalence of pain in older adults living in nursing homes in Japan by using self-reporting and the Abbey Pain Scale-Japanese version (APS-J) and to explore factors related to pain. This is a descriptive study. Residents in two Special Nursing Homes for the Elderly in Tokyo, Japan, were asked to participate in this study, with the exclusion of short-term temporary residents. Data collected from participating residents included their demographics and the results from the Barthel Index, the Folstein Mini-Mental State Examination, the APS-J, and the Verbal Descriptor Scale for pain. The residents were divided into two groups: residents able to report their pain (self-report group) and residents not able to report their pain. The second group was assessed by using the APS-J (APS-J group). The Mann-Whitney U test, the χ2 test, and logistic analyses were performed to derive factors related to pain prevalence. Data were obtained from 171 residents. The prevalence of pain in the self-report group (n = 96) was 41.7%. For the 75 residents unable to report their pain, 52.0% were assessed by the APS-J to have pain. The overall pain prevalence of all residents was 46.2%. Age, Barthel Index score, and length of time of institutionalization were significantly associated with residents' pain in the APS-J group. Logistic regression analysis showed that contracture (odds ratio 3.8) and previous injury (odds ratio 3.4) were associated with residents' pain in the self-report group, whereas only the length of nursing home stay (odds ratio 1.03) was a predictor for pain in the APS-J group. Nearly one-half of residents had pain when they moved or were moved. Pain assessment and management is needed for residents. Copyright © 2013 American Society for Pain

The nonlinear optical properties of a phosphate vitreous system [(ZnO) x − (MgO) 30−x − (P 2 O 5 ) 70 ], where x = 8, 10, 15, 18, and 20 mol% synthesized through the melt-quenching technique have been investigated by using the Z-scan technique. In the experiment, a continuous-wave laser with a wavelength of 405 nm was utilized to determine the sign and value of the nonlinear refractive (NLR) index and the absorption coefficient with closed and opened apertures of the Z-scan setup. The NLR index was found to increase with the ZnO concentration in the glass samples by an order of 10 −10 cm 2 ·W −1 . The real and imaginary parts of the third-order nonlinear susceptibility were calculated by referring to the NLR index (n 2 ) and absorption coefficient (β) of the samples. The value of the third-order nonlinear susceptibility was presented by nonlinear refractive or absorptive behavior of phosphate glasses for proper utilization in nonlinear optical devices. Based on the measurement, the positive sign of the NLR index shows a self-focusing phenomenon. The figures of merit for each sample were calculated to judge the potential of phosphate glasses for application in optical switching

Dense sheet Z-pinches

International Nuclear Information System (INIS)

Tetsu, Miyamoto

1999-01-01

The steady state and quasi-steady processes of infinite- and finite-width sheet z-pinches are studied. The relations corresponding to the Bennett relation and Pease-Braginskii current of cylindrical fiber z-pinches depend on a geometrical factor in the sheet z-pinches. The finite-width sheet z-pinch is approximated by a segment of infinite-width sheet z-pinch, if it is wide enough, and corresponds to a number of (width/thickness) times fiber z-pinch plasmas of the diameter that equals the sheet thickness. If the sheet current equals this number times the fiber current, the plasma created in the sheet z-pinches is as dense as in the fiber z-pinches. The total energy of plasma and magnetic field per unit mass is approximately equal in both pinches. Quasi-static transient processes are different in several aspects from the fiber z-pinch. No radiation collapse occurs in the sheet z-pinch. The stability is improved in the sheet z-pinches. The fusion criterions and the experimental arrangements to produce the sheet z-pinches are also discussed. (author)

To what extent are medicinal plants shared between country home gardens and urban ones? A case study from Misiones, Argentina.

Furlan, Violeta; Kujawska, Monika; Hilgert, Norma Ines; Pochettino, María Lelia

2016-09-01

Context Worldwide ethnobotanical research has shown the importance of home gardens as sources of medicinal plants. These resources are worthy of further study in the Argentinean Atlantic Forest due to the richness of medicinal flora and their importance for local people. Objective We studied richness, composition, cultural importance and medicinal uses of plants in home gardens of rural, semirural and urban areas in the Iguazú Department (Misiones, Argentina). Our hypothesis claims that people living in different environments have a similar array of medicinal plants in their gardens and they use them in a similar way. Materials and methods The analysis was based on 76 interviews and plant inventories of home gardens. During guided walks in gardens, voucher specimens were collected. To analyse composition, Simpson similarity index was applied and a new index was proposed to measure culturally salient species. Results All the environments had similar species composition with species differing in less than 30% of them. The most culturally salient taxa were Mentha spicata L. (Lamiaceae), in rural, Artemisia absinthium L. (Asteraceae), in semirural, and Aloe maculata All. (Xanthorrhoeaceae), in urban areas. The body systems treated with medicinal plants were similar across study sites. Discussion The results suggest a "core repertoire" of medicinal plants and a widespread exchange of plants among local population. The cultural importance index informs us about plant adaptability, based on the efficacy and the versatility of medicinal resources. Conclusion In this changing context where mobility and migrations constitute everyday life, medicinal plants in home gardens are part of local healthcare sovereignty.

Testing a diagnosis-related group index for skilled nursing facilities

Science.gov (United States)

Cotterill, Philip G.

1986-01-01

Interest in case-mix measures for use in nursing home payment systems has been stimulated by the Medicare prospective payment system (PPS) for short-term acute-care hospitals. Appropriately matching payment with care needs is important to equitably compensate providers and to encourage them to admit patients who are most in need of nursing home care. The skilled nursing facility (SNF) Medicare benefit covers skilled convalescent or rehabilitative care following a hospital stay. Therefore, it might appear that diagnosis-related groups (DRG's), the basis for patient classification in PPS, could also be used for the Medicare SNF program. In this study, a DRG-based case-mix index (CMI) was developed and tested to determine how well it explains cost differences among SNF's. The results suggest that a DRG-based SNF payment system would be highly problematic. Incentives of this system would appear to discourage placement of patients who require relatively expensive care.

The present study aims to describe dietary intake and dietary adequacy according to eating location in preschool children. A sub-sample of 2414 children from the Generation XXI birth cohort (Porto, Portugal), evaluated during the follow-up between 2009 and 2011, was included. Dietary intake was assessed by 3 d food diaries and four groups of children were defined according to the eating location: 'Home' ( ≥ 80% of meals at home), 'Other homes', 'Preschool' and 'Restaurants'. A dietary adequacy index was developed based on general recommendations for children; a higher score represents a better dietary adequacy. The comparison of nutrients and foods daily intake according to the eating location groups was performed by ANOVA and ANCOVA to adjust for potential confounders. Children classified in 'Preschool' group ate significantly more vegetables, fruit, bread and fish, and less meat, compared to children classified into the 'Home' group. Children classified in the 'Restaurants' group ate more cakes, salty snacks and fruit juices than children in 'Home' group; and less vegetables, dairy products and pasta/rice/potatoes. In 'Restaurants' children obtained the lowest mean score of the dietary adequacy index (15.5, 95% CI 14.8, 16.3) and in 'Preschool' children had the highest mean score (18.3, 95% CI 18.1, 18.4), corresponding to a better dietary adequacy. Preschools seem to have a relevant role in promoting the intake of healthy foods in preschool children. The consumption in restaurants/coffee shops seems to contribute to energy-dense food intake and reduced consumption of nutrient-dense foods.

Around the world, populations are aging and there is a growing concern about ways that older adults can maintain their health and well-being while living in their homes. The aim of this paper was to conduct a systematic literature review to determine: (1) the levels of technology readiness among older adults and, (2) evidence for smart homes and home-based health-monitoring technologies that support aging in place for older adults who have complex needs. We identified and analyzed 48 of 1863 relevant papers. Our analyses found that: (1) technology-readiness level for smart homes and home health monitoring technologies is low; (2) the highest level of evidence is 1b (i.e., one randomized controlled trial with a PEDro score ≥6); smart homes and home health monitoring technologies are used to monitor activities of daily living, cognitive decline and mental health, and heart conditions in older adults with complex needs; (3) there is no evidence that smart homes and home health monitoring technologies help address disability prediction and health-related quality of life, or fall prevention; and (4) there is conflicting evidence that smart homes and home health monitoring technologies help address chronic obstructive pulmonary disease. The level of technology readiness for smart homes and home health monitoring technologies is still low. The highest level of evidence found was in a study that supported home health technologies for use in monitoring activities of daily living, cognitive decline, mental health, and heart conditions in older adults with complex needs.

Full Text Available Abstract Background Approximately one third of New Zealand children and young people are overweight or obese. A similar proportion (33% do not meet recommendations for physical activity, and 70% do not meet recommendations for screen time. Increased time being sedentary is positively associated with being overweight. There are few family-based interventions aimed at reducing sedentary behavior in children. The aim of this trial is to determine the effects of a 24 week home-based, family oriented intervention to reduce sedentary screen time on children's body composition, sedentary behavior, physical activity, and diet. Methods/Design The study design is a pragmatic two-arm parallel randomized controlled trial. Two hundred and seventy overweight children aged 9-12 years and primary caregivers are being recruited. Participants are randomized to intervention (family-based screen time intervention or control (no change. At the end of the study, the control group is offered the intervention content. Data collection is undertaken at baseline and 24 weeks. The primary trial outcome is child body mass index (BMI and standardized body mass index (zBMI. Secondary outcomes are change from baseline to 24 weeks in child percentage body fat; waist circumference; self-reported average daily time spent in physical and sedentary activities; dietary intake; and enjoyment of physical activity and sedentary behavior. Secondary outcomes for the primary caregiver include change in BMI and self-reported physical activity. Discussion This study provides an excellent example of a theory-based, pragmatic, community-based trial targeting sedentary behavior in overweight children. The study has been specifically designed to allow for estimation of the consistency of effects on body composition for Māori (indigenous, Pacific and non-Māori/non-Pacific ethnic groups. If effective, this intervention is imminently scalable and could be integrated within existing weight

The objective of this controlled clinical study was to evaluate the association between oral health and 1-year mortality among nursing home residents with or without oral health intervention. This research was part of a multidisciplinary intervention study (EVI-P) performed in 14 nursing homes in Germany. Two-hundred and nineteen nursing home residents were included in the study and assigned to an intervention group, for which dental health education was offered and ultrasonic baths were used for denture cleaning (n = 144), or to a control group (n = 75). Before the intervention, each participant was examined, and dental status, plaque control record (PCR), Denture Hygiene Index, and results from the Revised Oral Assessment Guide were recorded. Amount of care needed and dementia were also assessed, by use of the Barthel Index and the Mini Mental State Examination, respectively. Participant mortality was determined after 12 months, and bivariate analysis and logistic regression models were used to evaluate possible factors affecting mortality. Bivariate analysis detected a direct association between greater mortality and being in the control group (p = .038). Participants with higher PCR were also more likely to die during the study period (p = .049). For dentate participants, the protective effect of being in the intervention group was confirmed by multivariate analysis in which covariates such as age and gender were considered. Oral hygiene and oral health seem to affect the risk of mortality of nursing home residents. Dental intervention programs seem to reduce the risk of 1-year mortality among nursing home residents having remaining natural teeth. Further studies, with larger sample sizes and evaluation of the causes of death, are necessary to investigate the reasons for these associations.

Due to the ageing population, there is an increased demand for home care services. Restorative care is one approach to improving home care services, although there is little evidence to support its use in the community setting. The objective of this trial was to evaluate the impact of a restorative home care service for community-dwelling older people. The study was a cluster randomised controlled trial undertaken at a home care agency in New Zealand. The study period was from December 2005 to May 2007. Older people were interviewed face-to-face at baseline, four and 7 months. A total of 186 older people who received assistance from a home care agency participated in the study, 93 received restorative home care and 93 older people received usual home care. The primary outcome measure was change in health-related quality of life (measured by the Short Form 36 [SF36] Health Survey). Secondary outcomes were the physical, mental, and social well-being of older people (Nottingham Extended Activities of Daily Living, Timed Up and Go, Mastery scale, Duke Social Support Index). Findings revealed that compared with usual care, the intervention demonstrated a statistically significant benefit in health-related quality of life (SF36) at 7 months for older people (mean difference 3.8, 95% CI -0.0 to 7.7, P = 0.05). There were no changes in other scale measurements for older people in either group over time. There was a statistically significant difference in the number of older people in the intervention group identified for reduced hours or discharge (29%) compared with the control group (0%) (P home care service may be of benefit to older people, and improves home care service efficacy. © 2011 Blackwell Publishing Ltd.

New properties of z-scaling: flavor independence and saturation at low z

International Nuclear Information System (INIS)

Zborovsky, I.; Tokarev, M.V.

2008-01-01

Experimental ISR, RHIC, and Tevatron data on inclusive cross sections of particles produced in high energy proton-(anti)proton collisions are analyzed in the framework of z-scaling. New features of the scaling function ψ(z) are established. These are flavor independence of ψ(z) including particles with heavy flavor content and saturation at low z. Flavor independence means that the shape of the scaling function ψ(z) is the same for different hadron species. Saturation corresponds to flattering of ψ(z) for low z < 0.1. Relations of model parameters used in data z-presentation with some thermodynamical quantities (entropy, specific heat, temperature) are discussed. It is shown that behavior of particle spectra at low z is controlled by a parameter c interpreted as specific heat of the created medium associated with production of the inclusive particle. The saturation regime of ψ(z) observed at low z is assumed to be preferable in searching for phase transitions of hadron matter and for study of nonperturbative QCD in high energy proton-(anti)proton collisions at U70, RHIC, Tevatron, and LHC

Structure of the Z Ring-associated Protein, ZapD, Bound to the C-terminal Domain of the Tubulin-like Protein, FtsZ, Suggests Mechanism of Z Ring Stabilization through FtsZ Cross-linking.

Cell division in most bacteria is mediated by the tubulin-like FtsZ protein, which polymerizes in a GTP-dependent manner to form the cytokinetic Z ring. A diverse repertoire of FtsZ-binding proteins affects FtsZ localization and polymerization to ensure correct Z ring formation. Many of these proteins bind the C-terminal domain (CTD) of FtsZ, which serves as a hub for FtsZ regulation. FtsZ ring-associated proteins, ZapA-D (Zaps), are important FtsZ regulatory proteins that stabilize FtsZ assembly and enhance Z ring formation by increasing lateral assembly of FtsZ protofilaments, which then form the Z ring. There are no structures of a Zap protein bound to FtsZ; therefore, how these proteins affect FtsZ polymerization has been unclear. Recent data showed ZapD binds specifically to the FtsZ CTD. Thus, to obtain insight into the ZapD-CTD interaction and how it may mediate FtsZ protofilament assembly, we determined the Escherichia coli ZapD-FtsZ CTD structure to 2.67 Å resolution. The structure shows that the CTD docks within a hydrophobic cleft in the ZapD helical domain and adopts an unusual structure composed of two turns of helix separated by a proline kink. FtsZ CTD residue Phe-377 inserts into the ZapD pocket, anchoring the CTD in place and permitting hydrophobic contacts between FtsZ residues Ile-374, Pro-375, and Leu-378 with ZapD residues Leu-74, Trp-77, Leu-91, and Leu-174. The structural findings were supported by mutagenesis coupled with biochemical and in vivo studies. The combined data suggest that ZapD acts as a molecular cross-linking reagent between FtsZ protofilaments to enhance FtsZ assembly. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

MzrA-EnvZ Interactions in the Periplasm Influence the EnvZ/OmpR Two-Component Regulon▿ †

Science.gov (United States)

Gerken, Henri; Misra, Rajeev

2010-01-01

MzrA was identified as a modulator of the EnvZ/OmpR two-component signal transduction system. Previous evidence indicated that MzrA interacts with EnvZ and modulates its enzymatic activities to influence OmpR phosphate (OmpR∼P) levels. Moreover, MzrA was shown to connect the bacterial envelope stress response systems CpxA/CpxR and σE to EnvZ/OmpR to widen the defensive response regulatory network. In this study, experiments were carried out to establish whether the membrane or periplasmic domain of MzrA is critical for MzrA-EnvZ interactions and to reveal MzrA residues that play an important role in these interactions. Data obtained from chimeric constructs, in which the transmembrane domain of MzrA was replaced with the unrelated transmembrane domain of NarX or signal sequence of PhoA, showed that the transmembrane domain residues of MzrA do not play a critical role in MzrA-EnvZ interactions. The importance of the periplasmic domain of MzrA in MzrA-EnvZ interactions was revealed by characterizing bifunctional, fully soluble, and periplasmically localized MalE::MzrA chimeras. This was further corroborated through the isolation of loss-of-function, single-amino-acid substitutions in the conserved periplasmic domain of MzrA that interfered with MzrA-EnvZ binding in a bacterial two-hybrid system. Together, the data suggest that the binding of MzrA to EnvZ influences the ability of EnvZ to receive and/or respond to environmental signals in the periplasm and modulate its biochemical output to OmpR.

A Lyman Break Galaxy Candidate at z ~ 9

Science.gov (United States)

Henry, Alaina L.; Malkan, Matthew A.; Colbert, James W.; Siana, Brian; Teplitz, Harry I.; McCarthy, Patrick

2008-06-01

We report the discovery of a z ~ 9 Lyman break galaxy candidate, selected from the NICMOS Parallel Imaging Survey as a J-dropout with J110 - H160 = 1.7. Spitzer/IRAC photometry reveals that the galaxy has a blue H160 - 3.6 μm color and a spectral break between 3.6 and 4.5 μm. We interpret this break as the Balmer break and derive a best-fit photometric redshift of z ~ 9. We use Monte Carlo simulations to test the significance of this photometric redshift, and we show that there is a 96% probability of z >= 7. We estimate that the lower limit to the comoving number density of such galaxies at z ~ 9 is phi > 3.8 × 10-6 Mpc-3. If the high redshift of this galaxy is confirmed, this will indicate that the luminous end of the rest-frame UV luminosity function has not evolved substantially from z ~ 9 to z ~ 3. Still, some small degeneracy remains between this z ~ 9 model and models at z ~ 2-3 deep optical imaging (reaching IAB ~ 29) can rule out the lower z models. This work is based in part on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory (JPL), California Institute of Technology, under a contract with NASA. Support for this work was provided by NASA through an award issued by JPL/Caltech. This work is also based in part on observations made with the NASA/ESA Hubble Space Telescope, obtained from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.

2010-08-01

Full Text Available Abstract Background The CQ Index for the elderly, a quality-of-care questionnaire administered by conducting interviews, is used to assess clients' experiences in Dutch nursing homes and homes for the elderly. This article describes whether inter-interviewer differences influence the perceived quality of healthcare services reported by residents, the size of this interviewer effect and the influence of the interviewer characteristics on CQ Index dimensions for public reporting. Methods Data from 4345 questionnaires was used. Correlations were calculated, reliability analyses were performed, and a multilevel analysis was used to calculate the degree of correlation between two interviewers within one health care institution. Five models were constructed and the Intra Class Correlation (ICC was calculated. Healthcare institutions were given 1-5 stars on every quality dimensions (1 = worst and 5 = best, adjusted for resident and interviewer characteristics. The effect of these characteristics on the assignment of the stars was investigated. Results In a multilevel approach, the ICC showed a significant amount of variance on five quality dimensions. Of the interviewer characteristics, only previous interviewing experience, the reason of interviewing and general knowledge of health care had a significant effect on the quality dimensions. Adjusting for interviewer characteristics did not affect the overall star assignment to the institutions regarding 7 of 12 quality dimensions. For the other five dimensions (Shared decision-making, Meals, Professional competency, Autonomy, and Availability of personnel a minor effect was found. Conclusions We have shown that training, the use of experienced interviewers, written instructions, supervision and educational meetings do not automatically prevent interviewer effects. While the results of this study can be used to improve the quality of services provided by these institutions, several CQ index dimensions

Computational modeling of z-pinch-driven hohlraum experiments on Z

The high-yield inertial confinement fusion concept based on a double-ended z-pinch driven hohlraum tolerates the degree of spatial inhomogeneity present in z-pinch plasma radiation sources by utilizing a relatively large hohlraum wall surface to provide spatial smoothing of the radiation delivered to the fusion capsule. The z-pinch radiation sources are separated from the capsule by radial spoke arrays. Key physics issues for this concept are the behavior of the spoke array (effect on the z-pinch performance, x-ray transmission) and the uniformity of the radiation flux incident on the surface of the capsule. Experiments are underway on the Z accelerator at Sandia National laboratories to gain understanding of these issues in a single-sided drive geometry. These experiments seek to measure the radiation coupling among the z-pinch, source hohlraum, and secondary hohlraum, as well as the uniformity of the radiation flux striking a foam witness ball diagnostic positioned in the secondary hohlraum. This paper will present the results of computational modeling of various aspects of these experiments

Screen-based activities, such as watching television (TV), playing video games, and using computers, are common sedentary behaviors among young people and have been linked with increased energy intake and overweight. Previous home-based sedentary behaviour interventions have been limited by focusing primarily on the child, small sample sizes, and short follow-up periods. The SWITCH (Screen-Time Weight-loss Intervention Targeting Children at Home) study aimed to determine the effect of a home-based, family-delivered intervention to reduce screen-based sedentary behaviour on body composition, sedentary behaviour, physical activity, and diet over 24 weeks in overweight and obese children. A two-arm, parallel, randomized controlled trial was conducted. Children and their primary caregiver living in Auckland, New Zealand were recruited via schools, community centres, and word of mouth. The intervention, delivered over 20 weeks, consisted of a face-to-face meeting with the parent/caregiver and the child to deliver intervention content, which focused on training and educating them to use a wide range of strategies designed to reduce their child's screen time. Families were given Time Machine TV monitoring devices to assist with allocating screen time, activity packages to promote alternative activities, online support via a website, and monthly newsletters. Control participants were given the intervention material on completion of follow-up. The primary outcome was change in children's BMI z-score from baseline to 24 weeks. Children (n = 251) aged 9-12 years and their primary caregiver were randomized to receive the SWITCH intervention (n = 127) or no intervention (controls; n = 124). There was no significant difference in change of zBMI between the intervention and control groups, although a favorable trend was observed (-0.016; 95% CI: -0.084, 0.051; p = 0.64). There were also no significant differences on secondary outcomes, except for a trend towards

Adults with stroke frequently experience executive dysfunction. Despite the range of assessments that examine the effects of executive dysfunction on daily tasks, there remains a paucity of literature that examines the influence of the environment on performance in the community. The MET-Home is an ecologically valid assessment for examining post-stroke executive dysfunction in the home environment. This qualitative study explores the relationship between the environment and MET-Home performance among home-dwelling adults with stroke and matched controls. Using a descriptive qualitative approach, we analysed video, interview, and observation notes from a MET-Home validation study. An overarching theme of interplay between everyday task performance and the home environment produced further themes: naturalistically emerging supports and barriers and environment as strategy. Within naturalistically emerging supports and barriers, five contextual sub-themes were discovered: physical environment, social environment, temporal context, virtual context, and personal context. Within environment as strategy, we identified four sub-themes: reducing distractions, using everyday technologies, planning in context, and seeking social support. These findings extend the conceptualisation of how we evaluate executive dysfunction in the context of the community to also consider the inherent influence of the environment.

PLANNED HOME BIRTH: A REVIEW

Directory of Open Access Journals (Sweden)

Tamara Serdinšek

2016-05-01

Full Text Available Background: Home birth is as old as humanity, but still most middle- and high-income countries consider hospitals as the safest birth settings, as complications regarding birth are highly unpredictable. Despite this there are a few countries in which home birth in integrated into official healthcare system (the Netherlands, United Kingdom, Canada etc.. Home births can be divided into unplanned and planned, and the latter can be further categorized by the presence of the birth attendants. This review focuses on planned home births, which are differently represented throughout the world. In the United States 0.6-1.0% of all children are born at home, in the United Kingdom 2-3%, in Canada 1.6% and in the Netherlands 20-30%. For Slovenia, the number of planned home births is unknown; however, in 2010 0.1% of children were born outside medical facilities.Conclusions: The safety of home birth in still under the debate. While research confirms smaller number of obstetric interventions and some complications in mothers who give birth at home, the data regarding the neonatal and perinatal mortality and morbidity is still conflicting. This confirms the need for large multicentric trials in this field. Current home birth guidelines emphasize that women should be well informed regarding the possible advantages and disadvantages of home births. In addition, the emphasis is on definition of selection criteria for home birth, indications for intrapartal transfer to the hospital and appropriate education of birth attendants.

We study the structural evolution of massive galaxies by linking progenitors and descendants at a constant cumulative number density of n{sub c} = 1.4 Multiplication-Sign 10{sup -4} Mpc{sup -3} to z {approx} 3. Structural parameters were measured by fitting Sersic profiles to high-resolution CANDELS HST WFC3 J{sub 125} and H{sub 160} imaging in the UKIDSS-UDS at 1 < z < 3 and ACS I{sub 814} imaging in COSMOS at 0.25 < z < 1. At a given redshift, we selected the HST band that most closely samples a common rest-frame wavelength so as to minimize systematics from color gradients in galaxies. At fixed n{sub c}, galaxies grow in stellar mass by a factor of {approx}3 from z {approx} 3 to z {approx} 0. The size evolution is complex: galaxies appear roughly constant in size from z {approx} 3 to z {approx} 2 and then grow rapidly to lower redshifts. The evolution in the surface mass density profiles indicates that most of the mass at r < 2 kpc was in place by z {approx} 2, and that most of the new mass growth occurred at larger radii. This inside-out mass growth is therefore responsible for the larger sizes and higher Sersic indices of the descendants toward low redshift. At z < 2, the effective radius evolves with the stellar mass as r{sub e} {proportional_to}M {sup 2.0}, consistent with scenarios that find dissipationless minor mergers to be a key driver of size evolution. The progenitors at z {approx} 3 were likely star-forming disks with r{sub e} {approx} 2 kpc, based on their low Sersic index of n {approx} 1, low median axis ratio of b/a {approx} 0.52, and typical location in the star-forming region of the U - V versus V - J diagram. By z {approx} 1.5, many of these star-forming disks disappeared, giving rise to compact quiescent galaxies. Toward lower redshifts, these galaxies continued to assemble mass at larger radii and became the local ellipticals that dominate the high-mass end of the mass function at the present epoch.

Being a last-born child and having a sister have been associated with higher body mass index (BMI). Encouragement to eat that overrides children's self-regulation has been reported to increase the risk of obesogenic eating behaviors. This study sought to test the hypothesis that encouragement to eat during mealtime from older siblings and sisters mediates associations of being last-born or having a sister with higher BMI. Children aged 4-8 years (n = 75) were videotaped while eating a routine evening meal at home with one sibling present. Encouragement to eat (defined as direct prompts to eat or general positive statements about food) delivered to the index child (IC) from the sibling was coded from the videotape. Path analysis was used to examine associations between IC's birth order, sibling's sex, encouragement counts, and IC's measured BMI z-score (BMIz). Being the younger sibling in the sibling dyad was associated with the IC receiving more encouragements to eat from the sibling (β: 0.93, 95 % confidence interval (CI): 0.59, 1.26, p eat from the sibling (β: 0.18, 95 % CI: -0.09, 0.47, p = 0.20). The IC receiving more encouragements to eat from the sibling was associated with lower IC BMIz (β: -0.06, 95 % CI: -0.12, 0.00, p = 0.05). Children were more likely to receive encouragements to eat from older siblings than younger siblings. Being the recipient of encouragements to eat from a sibling was associated with lower, not higher, child BMIz, which may reflect sibling modeling of maternal behavior. Future longitudinal studies are needed to examine whether encouragements to eat from siblings lead to increase in BMI over time. Encouragements from siblings may be a novel intervention target for obesity prevention.

A review of the experimental work performed at the GASP array with the purpose of the identification and first spectroscopic measurements of the heaviest even-even N = Z and odd-A N = Z + 1 nuclei (mass larger than 80) is made. Systematic experiments in this mass region led to the first study of seven such nuclei: 88 Ru, 81 Zr, 85 Mo, 89 Ru, 91 Rh, 93 Pd, and 95 Ag, and extensive data on many other nuclei in their neighborhood. The systematic evolution of the level structures in both even-even and odd-A nuclei, between N ∼ Z ∼ 40 and N ∼ Z ∼ 47 is briefly presented. The possibility that effects of the neutron-proton pairing have been observed, as well as the type of collectivity observed in this region are discussed. (author)

A Home Away from Home

The House of Tiny Tearaways (HTT) first appeared on British television in May 2005. Over a six-day period, three families are invited to reside in a specially designed house together with a resident clinical psychologist. The house is to be “a home away from home” for the resident families...... in order to analyze excerpts from the program and to explore how the affordances and constraints of the specially designed house—its architecture and spatial configuration, as well as the surveillance technology embedded within its walls—are assembled within particular familial activities, and how...... the relationships between family members are reshaped as a result. The analysis focuses on several key phenomena: 1) practices of video observation in relation to the domestic sphere; 2) use of inscription devices, such as video displays, to capture and visualize behavior and action in the “home;” 3) practicing...

Use of sinuosity indexes to describe freeranging cow paths

Sanuy, D.

Full Text Available An analysis of circular data was used to obtain vertical and horizontal sinuosity indexes of free-ranging cow paths. Focal sampling of cow displacements from 20 cows was translated from Cartesian co-ordinates (X,Y,Z to rotation angles and the first order correlated random walk model developed by BOVET & BENHAMOU (1988 was used to calculate sinuosity indexes. Some of the statistical hypotheses were hard to accomplish in some samples. Nevertheless, the obtained indexes summarized well the complete path of grazing animals and so it could be used in order to detect differences in animal behavior pattern.

Early researchers recogniZed the desirable features of the linear Z-pinch configuration as a magnetic fusion scheme. In particular, a Z-pinch reactor might not require auxiliary heating or external field coils, and could constitute an uncomplicated, high plasma β geometry. The simple Z pinch, however, exhibited gross MHD instabilities that disrupted the plasma, and the linear Z pinch was abandoned in favor of more stable configurations. Recent advances in pulsed-power technology and an appreciation of the dynamic behavior of an ohmically heated Z pinch have led to a reexamination of the Z pinch as a workable fusion concept

It is well recognised that the adoption and longer term adherence to physical activity by adults to reduce the risk of chronic disease is a challenge. Interventions, such as group and home based physical activity programs, have been widely reported upon. However few studies have directly compared these interventions over the longer term to determine their adherence and effectiveness. Participant preference for home based or group interventions is important. Some evidence suggests that home based physical activity programs are preferred by middle aged adults and provide better long term physical activity adherence. Physiotherapists may also be useful in increasing physical activity adherence, with limited research on their impact. 'Physical Activity at Home' is a 2 year pragmatic randomised control trial, with a non-randomised comparison to group exercise. Middle-aged adults not interested in, or unable to attend, a group exercise program will be targeted. Sedentary community dwelling 50-65 year olds with no serious medical conditions or functional impairments will be recruited via two mail outs using the Australian federal electoral roll. The first mail out will invite participants to a 6 month community group exercise program. The second mail out will be sent to those not interested in the group exercise program inviting them to take part in a home based intervention. Eligible home based participants will be randomised into a 6 month physiotherapy-led home based physical activity program or usual care. Outcome measures will be taken at baseline, 6, 12, 18 and 24 months. The primary outcome is physical activity adherence via exercise diaries. Secondary outcomes include the Active Australia Survey, accelerometry, aerobic capacity (step test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio and body mass index. Costs will be recorded prospectively and qualitative data will be collected. The planned 18 month follow-up post

Background Leadership and staffing are recognised as important factors for quality of care. This study examines the effects of ward leaders' task- and relationship-oriented leadership styles, staffing levels, ratio of registered nurses and ratio of unlicensed staff on three independent measures of quality of care. Methods A cross-sectional survey of forty nursing home wards throughout Norway was used to collect the data. Five sources of data were utilised: self-report questionnaires to 444 employees, interviews with and questionnaires to 13 nursing home directors and 40 ward managers, telephone interviews with 378 relatives and 900 hours of field observations. Separate multi-level analyses were conducted for quality of care assessed by relatives, staff and field observations respectively. Results Task-oriented leadership style had a significant positive relationship with two of the three quality of care indexes. In contrast, relationship-oriented leadership style was not significantly related to any of the indexes. The lack of significant effect for relationship-oriented leadership style was due to a strong correlation between the two leadership styles (r = 0.78). Staffing levels and ratio of registered nurses were not significantly related to any of the quality of care indexes. The ratio of unlicensed staff, however, showed a significant negative relationship to quality as assessed by relatives and field observations, but not to quality as assessed by staff. Conclusions Leaders in nursing homes should focus on active leadership and particularly task-oriented behaviour like structure, coordination, clarifying of staff roles and monitoring of operations to increase quality of care. Furthermore, nursing homes should minimize use of unlicensed staff and address factors related to high ratios of unlicensed staff, like low staff stability. The study indicates, however, that the relationship between staffing levels, ratio of registered nurses and quality of care is

While the potential benefits of smart home technology are widely recognized, a lightweight design is needed for the benefits to be realized at a large scale. We introduce the CASAS "smart home in a box", a lightweight smart home design that is easy to install and provides smart home capabilities out of the box with no customization or training. We discuss types of data analysis that have been performed by the CASAS group and can be pursued in the future by using this approach to designing and implementing smart home technologies.

There has been increasing interest in tomato products rich in lycopene Z-isomers since these carotenoids present greater bioavailability and antioxidant capacity than the all-E lycopene form. Intrinsic food properties as well as processing and the interaction between dietary components can all influence the content, type and bioavailability of carotenoids. The aim of this study was to evaluate whether carotenoid content and isomerization in tomato-based Mediterranean sofrito is affected by the process of home cooking and the presence of other ingredients such as extra virgin olive oil, onion and garlic. We used a full factorial design to clarify the contribution of each ingredient to the carotenoid composition of sofrito and to determine whether this can be improved by the cooking time and ingredient synergism. Cooking time and onion content were associated with a higher production of 5-Z-lycopene, 9-Z-lycopene and 13-Z-lycopene in sofrito. Onion proved to be the most interesting ingredient in the sofrito formulation due to their enhancing effect on lycopene isomerization. The use of onion combined with an adequate processing time may improve the bioavailability of lycopene in tomato products. Copyright © 2017 Elsevier Ltd. All rights reserved.

To explore effects of FtsZ mutants FtsZ(E75A), FtsZ(R78G) and FtsZ(D82A) on FtsZ self-assembly and interaction of FtsZ with MreB in Escherichia coli strains. METHODS) We constructed FtsZ and its mutant's plasmids by molecular clone and site-directed mutagenesis methods, and purified targeted proteins by affinity chromatography. QN6(ftsZ::yfp-cat), QN7(tsZ::yfp-cat), QN8(ftsZ(R78G)::yfp-cat) and QN9 (ftsZ(D82A):.:yfp-cat) strains were constructed by linear DNA homologous recombination. We observed cellular localization pattern of FtsZ and its mutants in E. coli by living cell imaging experiments, examined interaction of FtsZ/FtsZ*-FtsZ* and FtsZ/FtsZ*-MreB by Coimmunoprecipitation and bacteria two hybrid, and analyzed assembly characteristics of FtsZ mutants by Light scattering. RESULTS) The Yfp-labeled FtsZ(E75A), FtsZ(R78G) and FtsZ(D82A) mutant proteins failed to assemble into functional Z-ring structure and localize correctly in E. coli strains. Interaction of FtsZ with its mutants, or FtsZ*-FtsZ* and FtsZ*-MreB interaction were weakened or completely disappeared. In addition, in vitro experiments show that E75A, R78G and D82A mutations decreased the polymerization efficiency of FtsZ monomer. FtsZ E75, R78 and D82 are critical amino acids in the assembly, function of FtsZ protein and FtsZ-MreB interaction in E. coli strains.

A protective effect of obesity on death has been reported in the context of various co-morbidities. We studied if the obesity paradox applied to nursing home (NH) older residents according to dementia status. Prospective data from 3741 NH residents from France. All-cause mortality was the dependent measure. Subjects were categorized according with body mass index (BMI) as underweight, normal-weight, overweight, and obese. Dementia status was obtained from medical charts. Cox regressions were performed. There were 344 (9.2%) residents who were underweight, 1367 (43.8%) normal weight, 1069 (28.6%) overweight and 691 (18.5%) obese. 1083 (28.9%) people died during follow-up. In residents with dementia, mortality risk was reduced by almost half in overweight and obese people (HRs of 0.60 [0.48-0.76] and 0.53 [0.38-0.75], respectively; p paradox in very old and functionally limited NH residents. Therefore, weight loss in NH residents, particularly in people with dementia, should be considered with extreme caution even for obese people.

Home health care services are expanding at a rapid pace in order to meet the needs of the growing population of older adults and those with chronic illnesses. Because of current restrictions on home health care as an insured service in some countries, individuals may be required to pay for some or all of their home care services out of pocket. These payments may potentially limit access to needed home care services for persons in the lowest socioeconomic strata. Previous research demonstrates a clear socioeconomic gradient in access to acute and primary care services, where those most in need of services are the most disadvantaged and under-serviced. There has been little attention paid thus far, however, to the way in which socioeconomic status may affect the receipt of home health care services. To determine what is known from existing literature about socioeconomic disparities in home health care access and utilization. A scoping review was used to map the extent and nature of the literature in this area. A search of the databases CINAHL, Medline, SocIndex and Sociological Abstracts as well as Dissertations International. A total of 206 potentially relevant articles were published between 2000 and April 2011. Two reviewers independently reviewed the articles, leaving 15 research articles to be included in the scoping review. The majority of articles reported secondary analyses of administrative datasets related to utilization of home health care. Several studies examined access and utilization using qualitative approaches. The distinction between professional and supportive home care services was not always clear in the articles. Individual and composite measures of socioeconomic status were reported, with the most frequently used indicator being income. Several studies used more complex composite ecological indicators of socieconomic status. There was general agreement that utilization of home health services favored persons with greater economic disadvantage

Nonlinear transmission of 80 and 140fs pulsed light with 0.79μm wavelength through single walled carbon nanotubes suspended in water containing sodium dodecyl sulfate is studied. Pulse-width independent saturation absorption and negative cubic nonlinearity are observed, respectively, in open and closed aperture z-scan experiments. The theoretical expressions derived to analyze the z-dependent transmission in the saturable limit require two photon absorption coefficient β0˜1.4cm/MW and a nonlinear index γ ˜-5.5×10-11cm2/W to fit the data.

We present the discovery of one or two extremely faint z ∼ 6 quasars in 6.5 deg 2 utilizing a unique capability of the wide-field imaging of the Subaru/Suprime-Cam. The quasar selection was made in (i'-z B ) and (z B -z R ) colors, where z B and z R are bandpasses with central wavelengths of 8842 Å and 9841 Å, respectively. The color selection can effectively isolate quasars at z ∼ 6 from M/L/T dwarfs without the J-band photometry down to z R < 24.0, which is 3.5 mag deeper than the Sloan Digital Sky Survey (SDSS). We have selected 17 promising quasar candidates. The follow-up spectroscopy for seven targets identified one apparent quasar at z = 6.156 with M 1450 = –23.10. We also identified one possible quasar at z = 6.041 with a faint continuum of M 1450 = –22.58 and a narrow Lyα emission with HWHM =427 km s –1 , which cannot be distinguished from Lyman α emitters. We derive the quasar luminosity function at z ∼ 6 by combining our faint quasar sample with the bright quasar samples by SDSS and CFHQS. Including our data points invokes a higher number density in the faintest bin of the quasar luminosity function than the previous estimate employed. This suggests a steeper faint-end slope than lower z, though it is yet uncertain based on a small number of spectroscopically identified faint quasars, and several quasar candidates still remain to be diagnosed. The steepening of the quasar luminosity function at the faint end does increase the expected emission rate of the ionizing photon; however, it only changes by a factor of approximately two to six. This was found to still be insufficient for the required photon budget of reionization at z ∼ 6

Z Score and CIAF – A comprehensive measure of magnitude of undernutrition in a rural school going population of Kashmir, India

Full Text Available WHO has recently recommended the use of Z-Score or SD system to grade undernutrition as this system allows us to measure all the three indices i.e. weight for age, height for age, weight for height. 438 school children in the age group of 5-9 years were clinically and anthropometrically assessed in order to estimate the prevalence of undernutrition using the Z-Score system of classification and the recently introduced Composite Index of Anthropometric Failure (CIAF .Only 112 (25.58% of these children were in a state of anthropometric failure as per the Z-Score system , 10.73% of them being underweight , 15.29% wasted and 8.90% stunted. The most common anthropometric failure in these children was wasting while 30.35% of these undernourished children had more than one anthropometric failure.Using underweight as the sole criteria for assessing the magnitude of undernutrition in this study would give us an underestimate and we would miss about 58% of the undernourished children in our study population.

The purpose of this study was to develop a multivariate fall risk assessment model beyond the current fall Resident Assessment Protocol (RAP) triggers for nursing home residents using the Minimum Data Set (MDS). Retrospective, clustered secondary data analysis. National Veterans Health Administration (VHA) long-term care nursing homes (N = 136). The study population consisted of 6577 national VHA nursing home residents who had an annual assessment during FY 2005, identified from the MDS, as well as an earlier annual or admission assessment within a 1-year look-back period. A dichotomous multivariate model of nursing home residents coded with a fall on selected fall risk characteristics from the MDS, estimated with general estimation equations (GEE). There were 17 170 assessments corresponding to 6577 long-term care nursing home residents. The increased odds ratio (OR) of being classified as a faller relative to the omitted "dependent" category of activities of daily living (ADL) ranged from OR = 1.35 for "limited" ADL category up to OR = 1.57 for "extensive-2" ADL (P canes, walkers, or crutches, or the use of wheelchairs increases the odds of being a faller (OR = 1.17, P falls in long-term care settings. The model incorporated an ADL index and adjusted for case mix by including only long-term care nursing home residents. The study offers clinicians practical estimates by combining multiple univariate MDS elements in an empirically based, multivariate fall risk assessment model.

Nucleoside diphosphate kinase (NDK), conserved across bacteria to humans, synthesises NTP from NDP and ATP. The eukaryotic homologue, the NDPK, uses ATP to phosphorylate the tubulin-bound GDP to GTP for tubulin polymerisation. The bacterial cytokinetic protein FtsZ, which is the tubulin homologue, also uses GTP for polymerisation. Therefore, we examined whether NDK can interact with FtsZ to convert FtsZ-bound GDP and/or free GDP to GTP to trigger FtsZ polymerisation. Recombinant and native NDK and FtsZ proteins of Mycobacterium smegmatis and Mycobacterium tuberculosis were used as the experimental samples. FtsZ polymersation was monitored using 90° light scattering and FtsZ polymer pelleting assays. The γ32P-GTP synthesised by NDK from GDP and γ32P-ATP was detected using thin layer chromatography and quantitated using phosphorimager. The FtsZ bound 32P-GTP was quantitated using phosphorimager, after UV-crosslinking, followed by SDS-PAGE. The NDK-FtsZ interaction was determined using Ni2+-NTA-pulldown assay and co-immunoprecipitation of the recombinant and native proteins in vitro and ex vivo, respectively. NDK triggered instantaneous polymerisation of GDP-precharged recombinant FtsZ in the presence of ATP, similar to the polymerisation of recombinant FtsZ (not GDP-precharged) upon the direct addition of GTP. Similarly, NDK triggered polymerisation of recombinant FtsZ (not GDP-precharged) in the presence of free GDP and ATP as well. Mutant NDK, partially deficient in GTP synthesis from ATP and GDP, triggered low level of polymerisation of MsFtsZ, but not of MtFtsZ. As characteristic of NDK's NTP substrate non-specificity, it used CTP, TTP, and UTP also to convert GDP to GTP, to trigger FtsZ polymerisation. The NDK of one mycobacterial species could trigger the polymerisation of the FtsZ of another mycobacterial species. Both the recombinant and the native NDK and FtsZ showed interaction with each other in vitro and ex vivo, alluding to the possibility of direct

We perform a systematic study of $B\\bar{B}^*$, $B^*\\bar{B}^*$, $D\\bar{D}^*$ and $D^*\\bar{D}^*$ systems by using effective interaction in our chiral quark model. Our results show that the interactions of $B\\bar{B}^*$, $B^*\\bar{B}^*$, $D\\bar{D}^*$ and $D^*\\bar{D}^*$ states are attractive, which consequently result in $B\\bar{B}^*$, $B^*\\bar{B}^*$, $D\\bar{D}^*$ and $D^*\\bar{D}^*$ bound states.

[A MULTIDISCIPLINARY BIOPSYCHOSOCIAL INTEGRATED APPROACH IN ORGANIZATION OF REHABILITATIVE ACTIVITY IN NURSING HOMES (RSA)].

2015-01-01

Objectives, social role and organization of Italian nursing homes (RSA) are characterized by a pronounced regional differentiation that causes situations which are difficult to compare about expected outcomes. The definition of a functional outcome is particularly difficult in institutionalized patients and this is due to the failure of a conclusive moment of the rehabilitative treatment. Furthermore we often take care of patients who have already been admitted to intensive and/or extensive rehabilitation units time after time, without further functional profit margin. The inconstant presence of professional figures of rehabilitation in nursing homes' staff makes difficult the drafting of an adequate rehabilitative project, especially for the multiple needs of frail old people. Starting with these assumptions, authors hypothesize and adopt a model of sanitary organization to consent a correct allocation of available resources, according to the patient's needs. They stratified all nursing home patients, using the Multidimensional Prognostic Index (MPI) and "Scheda di osservazione intermedia assistenza" (SOSIA), and measured the residual function. They concluded that a multidimensional evaluation of patients allows to identify wellness (of the sick person and of caregivers) as the main objective; nursing home organization could be think as a "complex supportive prosthesis for old people", made by the interaction among structure, operators and activities.

Many dietary interventions assume a positive influence of home cooking on diet, health and social outcomes, but evidence remains inconsistent. We aimed to systematically review health and social determinants and outcomes of home cooking. Given the absence of a widely accepted, established definition, we defined home cooking as the actions required for preparing hot or cold foods at home, including combining, mixing and often heating ingredients. Nineteen electronic databases were searched for relevant literature. Peer-reviewed studies in English were included if they focussed mainly on home cooking, and presented post 19 th century observational or qualitative data on participants from high/very high human development index countries. Interventional study designs, which have previously been reviewed, were excluded. Themes were summarised using narrative synthesis. From 13,341 unique records, 38 studies - primarily cross-sectional in design - met the inclusion criteria. A conceptual model was developed, mapping determinants of home cooking to layers of influence including non-modifiable, individual, community and cultural factors. Key determinants included female gender, greater time availability and employment, close personal relationships, and culture and ethnic background. Putative outcomes were mostly at an individual level and focused on potential dietary benefits. Findings show that determinants of home cooking are more complex than simply possessing cooking skills, and that potential positive associations between cooking, diet and health require further confirmation. Current evidence is limited by reliance on cross-sectional studies and authors' conceptualisation of determinants and outcomes. Crown Copyright © 2017. Published by Elsevier Ltd.

Anomalous aortic origin of the coronary arteries is associated with exercise-induced ischaemia, leading some physicians to restrict exercise in patients with this condition. We sought to determine whether exercise restriction was associated with increasing body mass index over time. From 1998 to 2015, 440 patients ⩽30 years old were enrolled into an inception cohort. Exercise-restriction status was documented in 143 patients. Using linear mixed model repeated-measures regression, factors associated with increasing body mass index z-score over time, including exercise restriction and surgical intervention as time-varying covariates, were investigated. The 143 patients attended 558 clinic visits for which exercise-restriction status was recorded. The mean number of clinic visits per patient was 4, and the median duration of follow-up was 1.7 years (interquartile range (IQR) 0.5-4.4). The median age at first clinic visit was 10.3 years (IQR 7.1-13.9), and 71% (101/143) were males. All patients were alive at their most recent follow-up. At the first clinic visit, 54% (78/143) were exercise restricted, and restriction status changed in 34% (48/143) during follow-up. The median baseline body mass index z-score was 0.2 (IQR 0.3-0.9). In repeated-measures analysis, neither time-related exercise restriction nor its interaction with time was associated with increasing body mass index z-score. Surgical intervention and its interaction with time were associated with decreasing body mass index z-score. Although exercise restriction was not associated with increasing body mass index over time, surgical intervention was associated with decreasing body mass index z-score over time in patients with anomalous aortic origin of the coronary arteries.

Objective: To compare and analyze the performance indexes and the imaging quality of the home and imported X-ray machines through testing their partial imaging performance parameters. Methods: By separate sampling from 10 home and 10 imported X-ray machines, the parameters including tube current, time of exposure, machine total exposure, and repeatability were tested, and the imaging performance was evaluated according to the national standard. Results: All the performance indexes met the standard of GB4505-84. The first sampling tests showed the maximum changing coefficient of imaging performance repeatability of the home X-ray machines was Δmax1 = 0.025, while that of the imported X-ray machine was Δmax1 = 0.016. In the second sampling tests, the maximum changing coefficients of the two were Δmax2 = 0.048 and Δmax2 = 0.022, respectively. Conclusion: The 2 years' follow-up tests indicate that there is no significant difference between the above-mentioned parameters of the elaborately adjusted home X-ray machines and imported ones, but the home X-ray machines are no better than the imported X-ray machines in stability and consistency

Recent developments in pulsed power technology demonstrate use of intense radiation sources (Z pinches) for driving planar shock waves in samples with spatial dimensions larger than possible with other radiation sources. Initial indications are that the use of Z pinch sources can be used to produce planar shock waves in samples with diameters of a few millimeters and thicknesses approaching one half millimeter. These dimensions allow increased accuracy of both shock velocity and particle velocity measurements. The Z pinch radiation source uses imploding metal plasma induced by self-magnetic fields applied to wire arrays to produce high temperature x-ray environments in vacuum hohlraum enclosures. Previous experiments have demonstrated that planar shock waves can be produced with this approach. A photograph of a wire array located inside the vacuum hohlraum is shown here. Typically, a few hundred individual wires are used to produce the Z pinch source. For the shock wave experiments being designed, arrays of 120 to 240 tungsten wires with a diameter of 40 mm and with individual diameters of about 10 microm are used. Preliminary experiments have been performed on the Z pulsed radiation source to demonstrate the ability to obtain VISAR measurements in the Z accelerator environment. Analysis of these results indicate that another effect, not initially anticipated, is an apparent change in refractive index that occurs in the various optical components used in the system. This effect results in an apparent shift in the frequency of reflected laser light, and causes an error in the measured particle velocity. Experiments are in progress to understand and minimize this effect

Context: Poststroke care in developing countries is inundated with poor concordance and scarce specialist stroke care providers. A primary care-driven health service is an option to ensure optimal care to poststroke patients residing at home in the community. Aims: We assessed outcomes of a pilot long-term stroke care clinic which combined secondary prevention and rehabilitation at community level. Settings and Design: A prospective observational study of stroke patients treated between 2008 and 2010 at a primary care teaching facility. Subjects and Methods: Analysis of patients was done at initial contact and at 1-year post treatment. Clinical outcomes included stroke risk factor(s) control, depression according to Patient Health Questionnaire (PHQ9), and level of independence using Barthel Index (BI). Statistical Analysis Used: Differences in means between baseline and post treatment were compared using paired t-tests or Wilcoxon-signed rank test. Significance level was set at 0.05. Results: Ninety-one patients were analyzed. Their mean age was 62.9 [standard deviation (SD) 10.9] years, mean stroke episodes were 1.30 (SD 0.5). The median interval between acute stroke and first contact with the clinic 4.0 (interquartile range 9.0) months. Mean systolic blood pressure decreased by 9.7 mmHg (t = 2.79, P = 0.007), while mean diastolic blood pressure remained unchanged at 80mmHg (z = 1.87, P = 0.06). Neurorehabilitation treatment was given to 84.6% of the patients. Median BI increased from 81 (range: 2−100) to 90.5 (range: 27−100) (Z = 2.34, P = 0.01). Median PHQ9 scores decreased from 4.0 (range: 0−22) to 3.0 (range: 0−19) though the change was not significant (Z= −0.744, P = 0.457). Conclusions: Primary care-driven long-term stroke care services yield favorable outcomes for blood pressure control and functional level. PMID:24347948

Robinett, R.W.; Rosner, J.L.

1982-01-01

Models based on SO(10) are presented in which a second Z (''Z 2 '') can have a mass as low as 230 GeV/c 2 without appreciably distorting the lower-energy picture. In such models the lightest Z(''Z 1 '') is very close to the predicted mass in the standard picture, 1 greater than or equal to M(Z 1 )/M(Z 0 ) greater than or equal to 0.98. The major constraint preventing M(Z 2 ) from being even lower comes from experiments on parity violation in heavy atoms. Other properties of Z 2 , and ways to discover it, are discussed

2008-01-01

, initial stages of precipitation of Z-phase have been studied and characterized using energy-filtered transmission electron microscopy (EFTEM). Vanadium nitrides were found to provide the most suitable nucleation site for Z-phase, since the misfit between the (0 0 1) planes of VN and Z-phase is very small....... Furthermore, such a nucleation site would provide vanadium and nitrogen for the growth of Z-phase. The presence of niobium carbide has also been observed close to Z-phase nucleation sites, indicating niobium to be important for the nucleation and growth of Z-phase....

Evolution of divergent DNA recognition specificities in VDE homing endonucleases from two yeast species.

Posey, Karen L; Koufopanou, Vassiliki; Burt, Austin; Gimble, Frederick S

2004-01-01

Homing endonuclease genes (HEGs) are mobile DNA elements that are thought to confer no benefit to their host. They encode site-specific DNA endonucleases that perpetuate the element within a species population by homing and disseminate it between species by horizontal transfer. Several yeast species contain the VMA1 HEG that encodes the intein-associated VMA1-derived endonuclease (VDE). The evolutionary state of VDEs from 12 species was assessed by assaying their endonuclease activities. Only two enzymes are active, PI-ZbaI from Zygosaccharomyces bailii and PI-ScaI from Saccharomyces cariocanus. PI-ZbaI cleaves the Z.bailii recognition sequence significantly faster than the Saccharomyces cerevisiae site, which differs at six nucleotide positions. A mutational analysis indicates that PI-ZbaI cleaves the S.cerevisiae substrate poorly due to the absence of a contact that is analogous to one made in PI-SceI between Gln-55 and nucleotides +9/+10. PI-ZbaI cleaves the Z.bailii substrate primarily due to a single base-pair substitution (A/T+5 --> T/A+5). Structural modeling of the PI-ZbaI/DNA complex suggests that Arg-331, which is absent in PI-SceI, contacts T/A+5, and the reduced activity observed in a PI-ZbaI R331A mutant provides evidence for this interaction. These data illustrate that homing endonucleases evolve altered specificity as they adapt to recognize alternative target sites.

We report the discovery of a protocluster at z {approx} 6 containing at least eight cluster member galaxies with spectroscopic confirmations in the wide-field image of the Subaru Deep Field (SDF). The overdensity of the protocluster is significant at the 6{sigma} level, based on the surface number density of i'-dropout galaxies. The overdense region covers {approx}6' Multiplication-Sign 6' (14 Mpc Multiplication-Sign 14 Mpc in comoving units at z = 6) and includes 30 i'-dropout galaxies. Follow-up spectroscopy revealed that 15 of these are real z {approx} 6 galaxies (5.7 < z < 6.3). Of these 15, 8 are clustering in a narrow redshift range ({Delta}z < 0.05 centered at z = 6.01), corresponding to a seven-fold increase in number density over the average in redshift space. We found no significant difference in the observed properties, such as Ly{alpha} luminosities and UV continuum magnitudes, between the eight protocluster members and the seven non-members. The velocity dispersion of the eight protocluster members is 647 {+-} 124 km s{sup -1}, which is about three times higher than that predicted by the standard cold dark matter model. This discrepancy could be attributed to the distinguishing three-dimensional distribution of the eight protocluster members. We discuss two possible explanations for this discrepancy: either the protocluster is already mature, with old galaxies at the center, or it is still immature and composed of three subgroups merging to become a larger cluster. In either case, this concentration of z = 6.01 galaxies in the SDF may be one of the first sites of formation of a galaxy cluster in the universe.

2012-01-01

Full Text Available WHO has recently recommended the use of Z-Score or SD system to grade undernutrition as this system allows us to measure all the three indices i.e. weight for age, height for age, weight for height. 438 school children in the age group of 5-9 years were clinically and anthropometrically assessed in order to estimate the prevalence of undernutrition using the Z-Score system of classification and the recently introduced Composite Index of Anthropometric Failure (CIAF .Only 112 (25.58% of these children were in a state of anthropometric failure as per the Z-Score system , 10.73% of them being underweight , 15.29% wasted and 8.90% stunted. The most common anthropometric failure in these children was wasting while 30.35% of these undernourished children had more than one anthropometric failure.Using underweight as the sole criteria for assessing the magnitude of undernutrition in this study would give us an underestimate and we would miss about 58% of the undernourished children in our study population.

Search for t Z' associated production induced by t c Z' couplings at the LHC

Hou, Wei-Shu; Kohda, Masaya; Modak, Tanmoy

2017-07-01

The P5' and RK anomalies, recently observed by the LHCb Collaboration in B →K(*) transitions, may indicate the existence of a new Z' boson, which may arise from gauged Lμ-Lτ symmetry. Flavor-changing neutral current Z' couplings, such as t c Z', can be induced by the presence of extra vector-like quarks. In this paper we study the LHC signatures of the induced right-handed t c Z' coupling that is inspired by, but not directly linked to, the B →K(*) anomalies. The specific processes studied are c g →t Z' and its conjugate process, each followed by Z'→μ+μ-. By constructing an effective theory for the t c Z' coupling, we first explore in a model-independent way the discovery potential of such a Z' at the 14 TeV LHC with 300 and 3000 fb-1 integrated luminosities. We then reinterpret the model-independent results within the gauged Lμ-Lτ model. In connection with t c Z', the model also implies the existence of a flavor-conserving c c Z' coupling, which can drive the c c ¯→Z'→μ+μ- process. Our study shows that existing LHC results for dimuon resonance searches already constrain the c c Z' coupling, and that the Z' can be discovered in either or both of the c g →t Z' and c c ¯→Z' processes. We further discuss the sensitivity to the left-handed t c Z' coupling and find that the coupling values favored by the B →K(*) anomalies lie slightly below the LHC discovery reach even with 3000 fb-1 .

The impact of obstructive sleep apnea variability measured in-lab versus in-home on sample size calculations

2009-01-01

Full Text Available Abstract Background When conducting a treatment intervention, it is assumed that variability associated with measurement of the disease can be controlled sufficiently to reasonably assess the outcome. In this study we investigate the variability of Apnea-Hypopnea Index obtained by polysomnography and by in-home portable recording in untreated mild to moderate obstructive sleep apnea (OSA patients at a four- to six-month interval. Methods Thirty-seven adult patients serving as placebo controls underwent a baseline polysomnography and in-home sleep study followed by a second set of studies under the same conditions. The polysomnography studies were acquired and scored at three independent American Academy of Sleep Medicine accredited sleep laboratories. The in-home studies were acquired by the patient and scored using validated auto-scoring algorithms. The initial in-home study was conducted on average two months prior to the first polysomnography, the follow-up polysomnography and in-home studies were conducted approximately five to six months after the initial polysomnography. Results When comparing the test-retest Apnea-hypopnea Index (AHI and apnea index (AI, the in-home results were more highly correlated (r = 0.65 and 0.68 than the comparable PSG results (r = 0.56 and 0.58. The in-home results provided approximately 50% less test-retest variability than the comparable polysomnography AHI and AI values. Both the overall polysomnography AHI and AI showed a substantial bias toward increased severity upon retest (8 and 6 events/hr respectively while the in-home bias was essentially zero. The in-home percentage of time supine showed a better correlation compared to polysomnography (r = 0.72 vs. 0.43. Patients biased toward more time supine during the initial polysomnography; no trends in time supine for in-home studies were noted. Conclusion Night-to-night variability in sleep-disordered breathing can be a confounding factor in assessing

Rare-earth-doped oxynitride or nitride compounds have been reported to be photoluminescent and may then serve as new phosphors because of their good thermal and chemical stabilities. In this work, Eu{sup 2+}-doped {beta}-SiAlON phosphor with a composition of Eu{sub x}Si{sub 6-z}Al{sub z}O{sub z}N{sub 8-z} (x=0.018,z=0.23) was prepared by gas-pressured solid state reaction. The crystallinity and particle morphology of the prepared phosphor were characterized. The Stokes shift and zero-phonon line were calculated mathematically and estimated from the spectral data. The temperature dependence of photoluminescence was measured from 25 to 250 C. The prepared Eu{sup 2+}-doped {beta}-SiAlON green phosphor showed superior thermal quenching property compared to silicate (SrBaSiO{sub 4}:Eu{sup 2+}) green phosphor. The white light-emitting diode (LED) back-lighting unit (BLU) using the prepared {beta}-SiAlON:Eu{sup 2+} green phosphor exhibited higher color gamut than a commercial silicate phosphor. (orig.)

The purpose of this study was to examine the association between adolescents' body mass index (BMI) z-scores and their subsequent level of schooling, extending previous longitudinal research by using objectively measured weight and height data. A longitudinal study with 3 study waves (1-year intervals) involving 1248 Dutch adolescents (49% girls; mean age = 13.7 years) at schools providing different educational levels was used to determine adolescents who moved and did not move to a lower educational level in the first year, or in the second year, and to examine whether this movement could be predicted by BMI z-scores (zBMI), after controlling for a large range of potential confounding factors. A total of 1164 Dutch adolescents continued in the same level of education, whereas 84 adolescents moved to a lower educational level (43 moved in the first and 41 in the second year). A higher zBMI significantly increased the risk of a general transition to a lower educational level, and of a transition in the first year, but not in the second year, after controlling for potential demographic, behavioral, and psychological confounds. Findings suggest that a higher zBMI during adolescence immediately lowers educational achievement level during general secondary education. © 2014, American School Health Association.

Early-life exposure to bisphenol A (BPA) may increase childhood obesity risk, but few prospective epidemiological studies have investigated this relationship. We sought to determine whether early-life exposure to BPA was associated with increased body mass index (BMI) at 2-5 years of age in 297 mother-child pairs from Cincinnati, Ohio (HOME Study). Urinary BPA concentrations were measured in samples collected from pregnant women during the second and third trimesters and their children at 1 and 2 years of age. BMI z-scores were calculated from weight/height measures conducted annually from 2 through 5 years of age. We used linear mixed models to estimate BMI differences or trajectories with increasing creatinine-normalized BPA concentrations. After confounder adjustment, each 10-fold increase in prenatal (β = -0.1; 95% CI: -0.5, 0.3) or early-childhood (β = -0.2; 95% CI: -0.6, 0.1) BPA concentrations was associated with a modest and nonsignificant reduction in child BMI. These inverse associations were suggestively stronger in girls than in boys [prenatal effect measure modification (EMM) p-value = 0.30, early-childhood EMM p-value = 0.05], but sex-specific associations were imprecise. Children in the highest early-childhood BPA tercile had lower BMI at 2 years (difference = -0.3; 95% CI: -0.6, 0.0) and larger increases in their BMI slope from 2 through 5 years (BMI increase per year = 0.12; 95% CI: 0.07, 0.18) than children in the lowest tercile (BMI increase per year = 0.07; 95% CI: 0.01, 0.13). All associations were attenuated without creatinine normalization. Prenatal and early-childhood BPA exposures were not associated with increased BMI at 2-5 years of age, but higher early-childhood BPA exposures were associated with accelerated growth during this period.

A smart home is a home environment enriched with sensing, actuation, communication and computation capabilities which permits to adapt it to inhabitants preferences and requirements. Establishing a proper strategy of actuation on the home environment can require complex computational tasks on the sensed data. This is the case of activity recognition, which consists in retrieving high-level knowledge about what occurs in the home environment and about the behaviour of the inhabitants. The inherent complexity of this application domain asks for tools able to properly support the design and implementation phases. This paper proposes a framework for the design and implementation of smart home applications focused on activity recognition in home environments. The framework mainly relies on the Cloud-assisted Agent-based Smart home Environment (CASE) architecture offering basic abstraction entities which easily allow to design and implement Smart Home applications. CASE is a three layered architecture which exploits the distributed multi-agent paradigm and the cloud technology for offering analytics services. Details about how to implement activity recognition onto the CASE architecture are supplied focusing on the low-level technological issues as well as the algorithms and the methodologies useful for the activity recognition. The effectiveness of the framework is shown through a case study consisting of a daily activity recognition of a person in a home environment.

While the potential benefits of smart home technology are widely recognized, a lightweight design is needed for the benefits to be realized at a large scale. We introduce the CASAS “smart home in a box”, a lightweight smart home design that is easy to install and provides smart home capabilities out of the box with no customization or training. We discuss types of data analysis that have been performed by the CASAS group and can be pursued in the future by using this approach to designing and...

Hypersymmetry: A Z3-graded generalization of supersymmetry

International Nuclear Information System (INIS)

Abramov, V.; Kerner, R.; Le Roy, B.

1997-01-01

We propose a generalization of non-commutative geometry and gauge theories based on ternary Z 3 -graded structures. In the new algebraic structures we define, all products of two entities are left free, the only constraining relations being imposed on ternary products. These relations reflect the action of the Z 3 -group, which may be either trivial, i.e., abc=bca=cab, generalizing the usual commutativity, or non-trivial, i.e., abc=jbca, with j=e (2πi)/3 . The usual Z 2 -graded structures such as Grassmann, Lie, and Clifford algebras are generalized to the Z 3 -graded case. Certain suggestions concerning the eventual use of these new structures in physics of elementary particles and fields are exposed. copyright 1997 American Institute of Physics

Decays A →Z γ γ and ϕ →Z γ γ (ϕ =h , H ) in two-Higgs doublet models

Science.gov (United States)

Sánchez-Vélez, R.; Tavares-Velasco, G.

2018-05-01

The one-loop contributions to the decays of the C P -odd and C P -even scalar bosons A →Z γ γ and ϕ →Z γ γ (ϕ =h , H ) are calculated within the framework of C P -conserving two-Higgs doublet models (THDMs), where they are induced by box and reducible Feynman diagrams. The behavior of the corresponding branching ratios are then analyzed within the type-II THDM in a region of the parameter space around the alignment limit and still consistent with experimental data. It is found that the A →Z γ γ branching ratio is only relevant when mA>mH+mZ , but it is negligible otherwise. For mA>600 GeV and tβ≃O (1 ), BR (A →Z γ γ ) can reach values of the order of 10-5-10-4, but it decreases by about 1 order of magnitude as tβ increases up to 10. A similar behavior is followed by the H →Z γ γ decay, which only has a non-negligible branching ratio when mH>mA+mZ and can reach the level of 10-4-10-3 for mH>600 GeV and tβ≃O (1 ). We also estimated the branching ratios of these rare decays in the type-I THDM, where they can be about 1 order of magnitude larger than in type-II THDM. As far as the h →Z γ γ decay is concerned, since the properties of this scalar boson must be nearly identical to those of the SM Higgs boson, the h →Z γ γ branching ratio does not deviate significantly from the SM prediction, where it is negligibly small, of the order of 10-9. This result is in agreement with previous calculations.

An extremely good reproduction of experimental excitation function of the 1n reactions producing Z=110,Z=111 and Z=112 is obtained by the two-step model and the statistical decay code KEWPIE. Thus, an extension of the recipe permits us to predict reliable values of the residue cross-sections of the elements Z=113 and Z=114 which will be a useful guide for planning of experiments.

Fusion with Z-pinches

Cook, D.

1998-06-01

In the past thirty-six months, great progress has been made in x-ray production using high-current z-pinches. Today, the x-ray energy and power output of the Z accelerator (formerly PBFA-II) is the largest available in the laboratory. These z-pinch x-ray sources have the potential to drive high-yield ICF reactions at affordable cost if several challenging technical problems can be overcome. In this paper, the recent technical progress with Z-pinches will be described, and a technical strategy for achieving high-yield ICF with z-pinches will be presented

A New N-Level Inverter Based on Z-NPC

Full Text Available First of all, in this paper, the topology and operation of the three-phase three-level Z-source inverter based on neutral-point-clamped (Z-NPC are studied. Moreover, different combinations of permissible switching states and control signals are explained for this inverter. In this paper, the topology of the three-phase three-level Z-NPC inverter is extended for an n-level state. Also, a combination of allowed switching states with relevant mathematical equations is presented for the proposed n-level Z-NPC inverter. In comparison with multilevel voltage-source inverters (only voltage-boost capability, the proposed multilevel Z-NPC inverter is a single-stage converter and it has a buck-boost capability of voltage. On the other hand, the control of two-stage converters compared to single-stage converters can be more difficult because of existing more active and passive components. In this paper, two new PWM control methods are also proposed for various multilevel Z-NPC inverters. One advantage of the proposed PWM control methods in comparison with conventional PWM control methods is maintaining the charge balance of the dc-link capacitors in neutral point. The correct performance of the proposed multilevel Z-NPC topology and PWM control methods are verified by the obtained results of analysis and simulations performed in the PSCAD software.

Research suggests that individuals experiencing homelessness have high rates of overweight and obesity. Unhealthy weights and homelessness are both associated with increased risk of poor health and mortality. Using longitudinal data from 575 participants at the Toronto site of the At Home/Chez Soi randomized controlled trial, we investigate the impact of receiving a Housing First intervention on the Body Mass Index (BMI) and waist circumference of participants with moderate and high needs for mental health support services. The ANCOVA results indicate that the intervention resulted in no significant change in BMI or waist circumference from baseline to 24 months. The findings suggest a need for a better understanding of factors contributing to overweight, obesity, and high waist circumference in populations who have histories of housing precarity and experience low-income in tandem with other concerns such as mental illness and addictions.

Validity of parent-reported weight and height of preschool children measured at home or estimated without home measurement: a validation study

Directory of Open Access Journals (Sweden)

Cox Bianca

2011-07-01

Full Text Available Abstract Background Parental reports are often used in large-scale surveys to assess children's body mass index (BMI. Therefore, it is important to know to what extent these parental reports are valid and whether it makes a difference if the parents measured their children's weight and height at home or whether they simply estimated these values. The aim of this study is to compare the validity of parent-reported height, weight and BMI values of preschool children (3-7 y-old, when measured at home or estimated by parents without actual measurement. Methods The subjects were 297 Belgian preschool children (52.9% male. Participation rate was 73%. A questionnaire including questions about height and weight of the children was completed by the parents. Nurses measured height and weight following standardised procedures. International age- and sex-specific BMI cut-off values were employed to determine categories of weight status and obesity. Results On the group level, no important differences in accuracy of reported height, weight and BMI were identified between parent-measured or estimated values. However, for all 3 parameters, the correlations between parental reports and nurse measurements were higher in the group of children whose body dimensions were measured by the parents. Sensitivity for underweight and overweight/obesity were respectively 73% and 47% when parents measured their child's height and weight, and 55% and 47% when parents estimated values without measurement. Specificity for underweight and overweight/obesity were respectively 82% and 97% when parents measured the children, and 75% and 93% with parent estimations. Conclusions Diagnostic measures were more accurate when parents measured their child's weight and height at home than when those dimensions were based on parental judgements. When parent-reported data on an individual level is used, the accuracy could be improved by encouraging the parents to measure weight and height

The achievements of the Z-machine; Les exploits de la Z-machine

Energy Technology Data Exchange (ETDEWEB)

Larousserie, D

2008-03-15

The ZR-machine that represents the latest generation of Z-pinch machines has recently begun preliminary testing before its full commissioning in Albuquerque (Usa). During its test the machine has well operated with electrical currents whose intensities of 26 million Ampere are already 2 times as high as the intensity of the operating current of the previous Z-machine. In 2006 the Z-machine reached temperatures of 2 billions Kelvin while 100 million Kelvin would be sufficient to ignite thermonuclear fusion. In fact the concept of Z-pinch machines was imagined in the fifties but the technological breakthrough that has allowed this recent success and the reborn of Z-machine, was the replacement of gas by an array of metal wires through which the electrical current flows and vaporizes it creating an imploding plasma. It is not well understood why Z-pinch machines generate far more radiation than theoretically expected. (A.C.)

Brief scales to assess physical activity and sedentary equipment in the home

2010-01-01

Full Text Available Abstract Background Sedentary behaviors such as TV viewing are associated with childhood obesity, while physical activity promotes healthy weight. The role of the home environment in shaping these behaviors among youth is poorly understood. The study purpose was to examine the reliability of brief parental proxy-report and adolescent self-report measures of electronic equipment and physical activity equipment in the home and to assess the construct validity of these scales by examining their relationship to physical activity, sedentary behavior, and weight status of children and adolescents. Methods Participants were adolescents (n = 189; mean age = 14.6, parents of adolescents (n = 171; mean age = 45.0, and parents of younger children (n = 116; parents mean age = 39.6; children's mean age = 8.3 who completed two surveys approximately one month apart. Measures included a 21-item electronic equipment scale (to assess sedentary behavior facilitators in the home, in the child or adolescent's bedroom, and portable electronics and a 14-item home physical activity equipment scale. Home environment factors were examined as correlates of children's and adolescents' physical activity, sedentary behavior, and weight status after adjusting for child age, sex, race/ethnicity, household income, and number of children in the home. Results Most scales had acceptable test-retest reliability (intraclass correlations were .54 - .92. Parent and adolescent reports were correlated. Electronic equipment in adolescents' bedrooms was positively related to sedentary behavior. Activity equipment in the home was inversely associated with television time in adolescents and children, and positively correlated with adolescents' physical activity. Children's BMI z-score was positively associated with having a television in their bedroom. Conclusions The measures of home electronic equipment and activity equipment were similarly reliable when reported by parents and by

A study on Z-phase nucleation in martensitic chromium steels

International Nuclear Information System (INIS)

Golpayegani, Ardeshir; Andren, Hans-Olof; Danielsen, Hilmar; Hald, John

2008-01-01

9-12% chromium martensitic steels are liable to the precipitation of Z-phase, Cr(V,Nb)N, after long time exposure at 550-650 deg. C. This complex nitride consumes vanadium nitrides and causes the creep strength of the material to fall drastically after several thousand hours of exposure. In this work, initial stages of precipitation of Z-phase have been studied and characterized using energy-filtered transmission electron microscopy (EFTEM). Vanadium nitrides were found to provide the most suitable nucleation site for Z-phase, since the misfit between the (0 0 1) planes of VN and Z-phase is very small. Furthermore, such a nucleation site would provide vanadium and nitrogen for the growth of Z-phase. The presence of niobium carbide has also been observed close to Z-phase nucleation sites, indicating niobium to be important for the nucleation and growth of Z-phase

We present a study of the infrared properties for a sample of seven spectroscopically confirmed submillimeter galaxies (SMGs) at z > 4.0. By combining ground-based near-infrared, Spitzer IRAC and MIPS, Herschel SPIRE, and ground-based submillimeter/millimeter photometry, we construct their spectral energy distributions (SEDs) and a composite model to fit the SEDs. The model includes a stellar emission component at λ rest < 3.5 μm, a hot dust component peaking at λ rest ∼ 5 μm, and cold dust component which becomes significant for λ rest > 50 μm. Six objects in the sample are detected at 250 and 350 μm. The dust temperatures for the sources in this sample are in the range of 40-80 K, and their L FIR ∼ 10 13 L ☉ qualifies them as hyper-luminous infrared galaxies. The mean FIR-radio index for this sample is around (q) = 2.2 indicating no radio excess in their radio emission. Most sources in the sample have 24 μm detections corresponding to a rest-frame 4.5 μm luminosity of Log 10 (L 4.5 /L ☉ ) = 11 ∼ 11.5. Their L 4.5 /L FIR ratios are very similar to those of starburst-dominated SMGs at z ∼ 2. The L CO – L FIR relation for this sample is consistent with that determined for local ULIRGs and SMGs at z ∼ 2. We conclude that SMGs at z > 4 are hotter and more luminous in the FIR but otherwise very similar to those at z ∼ 2. None of these sources show any sign of the strong QSO phase being triggered.

In this paper, we present a comprehensive analysis of star-forming galaxies (SFGs) at intermediate redshifts (z ˜ 1). We combine the ultra-deep optical spectro-photometric data from the Survey for High-z Absorption Red and Dead Sources (SHARDS) with deep UV-to-FIR observations in the GOODS-N field. Exploiting two of the 25 SHARDS medium-band filters, F687W17 and F823W17, we select [O ii] emission line galaxies at z ˜ 0.84 and z ˜ 1.23 and characterize their physical properties. Their rest-frame equivalent widths (EWrf([O ii])), line fluxes, luminosities, star formation rates (SFRs), and dust attenuation properties are investigated. The evolution of EWrf([O ii]) closely follows the SFR density evolution of the universe, with a trend of EWrf([O ii]) \\propto (1 + z)3 up to redshift z ≃ 1, followed by a possible flattening. The SF properties of the galaxies selected on the basis of their [O ii] emission are compared with complementary samples of SFGs selected by their MIR and FIR emission, and also with a general mass-selected sample of galaxies at the same redshifts. We demonstrate observationally that the UVJ diagram (or, similarly, a cut in the specific SFR) is only partially able to distinguish the quiescent galaxies from the SFGs. The SFR-M* relation is investigated for the different samples, yielding a logarithmic slope ˜1, in good agreement with previous results. The dust attenuations derived from different SFR indicators (UV(1600), UV(2800), [O ii], IR) are compared and show clear trends with respect to both the stellar mass and total SFR, with more massive and highly star-forming galaxies being affected by stronger dust attenuation.

To give an overview of empirical studies investigating nursing homes as a learning environment during nursing students' clinical practice. A supportive clinical learning environment is crucial to students' learning and for their development into reflective and capable practitioners. Nursing students' experience with clinical practice can be decisive in future workplace choices. A competent workforce is needed for the future care of older people. Opportunities for maximum learning among nursing students during clinical practice studies in nursing homes should therefore be explored. Mixed-method systematic review using PRISMA guidelines, on learning environments in nursing homes, published in English between 2005-2015. Search of CINAHL with Full Text, Academic Search Premier, MEDLINE and SocINDEX with Full Text, in combination with journal hand searches. Three hundred and thirty-six titles were identified. Twenty studies met the review inclusion criteria. Assessment of methodological quality was based on the Mixed Methods Appraisal Tool. Data were extracted and synthesised using a data analysis method for integrative reviews. Twenty articles were included. The majority of the studies showed moderately high methodological quality. Four main themes emerged from data synthesis: "Student characteristic and earlier experience"; "Nursing home ward environment"; "Quality of mentoring relationship and learning methods"; and "Students' achieved nursing competencies." Nursing home learning environments may be optimised by a well-prepared academic-clinical partnership, supervision by encouraging mentors and high-quality nursing care of older people. Positive learning experiences may increase students' professional development through achievement of basic nursing skills and competencies and motivate them to choose the nursing home as their future workplace. An optimal learning environment can be ensured by thorough preplacement preparations in academia and in nursing home wards

X-ray powder diffraction measurements and differential thermal analysis (DTA) were made on polycrystalline samples of the Cu 2 Cd 1-z Mn z GeSe 4 and Cu 2 Cd 1-z Fe z GeSe 4 alloy systems. The diffraction patterns were used to show the equilibrium conditions and to derive lattice parameter values. The effect of the annealing temperature and cooling rate to room temperature are discussed. For the Cu 2 Cd 1-z Fe z GeSe 4 system, only two single solid phase fields, the tetragonal stannite α and the wurtz-stannite δ structures were found to occur in the diagram. For the Cu 2 Cd 1-z Mn z GeSe 4 system, in addition to the tetragonal stannite α and the wurtz-stannite δ phases, MnSe was found to exist in the diagram. The DTA experiments showed that the cooling curves for both systems exhibited effects of undercooling

[Mobile geriatric rehabilitation in nursing homes, in short-term care facilities and private homes : Setting-specific analysis of nationwide treatment documentation (Part 2)].

Science.gov (United States)

Pippel, Kristina; Meinck, M; Lübke, N

2017-06-01

Mobile geriatric rehabilitation can be provided in the setting of nursing homes, short-term care (STC) facilities and exclusively in private homes. This study analyzed the common features and differences of mobile rehabilitation interventions in various settings. Stratified by setting 1,879 anonymized mobile geriatric rehabilitation treatments between 2011 and 2014 from 11 participating institutions were analyzed with respect to patient, process and outcome-related features. Significant differences between the settings nursing home (n = 514, 27 %), STC (n = 167, 9 %) and private homes (n = 1198, 64 %) were evident for mean age (83 years, 83 years and 80 years, respectively), percentage of women (72 %, 64 % and 55 %), degree of dependency on pre-existing care (92 %, 76 % and 64 %), total treatment sessions (TS, 38 TS, 42 TS and 41 TS), treatment duration (54 days, 61 days and 58 days) as well as the Barthel index at the start of rehabilitation (34 points, 39 points and 46 points) and the gain in the Barthel index (15 points, 21 points and 18 points), whereby the gain in the capacity for self-sufficiency was significant in all settings. The setting-specific evaluation of mobile geriatric rehabilitation showed differences for relevant patient, process and outcome-related features. Compared to inpatient rehabilitation mobile rehabilitation in all settings made an above average contribution to the rehabilitation of patients with pre-existing dependency on care. The gains in the capacity for self-sufficiency achieved in all settings support the efficacy of mobile geriatric rehabilitation under the current prerequisites for applicability.

Z2×Z2 generalizations of 𝒩 =2 super Schrödinger algebras and their representations

Science.gov (United States)

Aizawa, N.; Segar, J.

2017-11-01

We generalize the real and chiral N =2 super Schrödinger algebras to Z2×Z2-graded Lie superalgebras. This is done by D-module presentation, and as a consequence, the D-module presentations of Z2×Z2-graded superalgebras are identical to the ones of super Schrödinger algebras. We then generalize the calculus over the Grassmann number to Z2×Z2 setting. Using it and the standard technique of Lie theory, we obtain a vector field realization of Z2×Z2-graded superalgebras. A vector field realization of the Z2×Z2 generalization of N =1 super Schrödinger algebra is also presented.

We use HST/WFC3 imaging from the CANDELS Multi-Cycle Treasury Survey, in conjunction with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies with stellar masses >3 Multiplication-Sign 10{sup 10} M{sub Sun} from z = 2.2 to the present epoch, a time span of 10 Gyr. We explore the relationship between rest-frame optical color, stellar mass, star formation activity, and galaxy structure. We confirm the dramatic increase from z = 2.2 to the present day in the number density of non-star-forming galaxies above 3 Multiplication-Sign 10{sup 10} M{sub Sun} reported by others. We further find that the vast majority of these quiescent systems have concentrated light profiles, as parameterized by the Sersic index, and the population of concentrated galaxies grows similarly rapidly. We examine the joint distribution of star formation activity, Sersic index, stellar mass, inferred velocity dispersion, and stellar surface density. Quiescence correlates poorly with stellar mass at all z < 2.2. Quiescence correlates well with Sersic index at all redshifts. Quiescence correlates well with 'velocity dispersion' and stellar surface density at z > 1.3, and somewhat less well at lower redshifts. Yet, there is significant scatter between quiescence and galaxy structure: while the vast majority of quiescent galaxies have prominent bulges, many of them have significant disks, and a number of bulge-dominated galaxies have significant star formation. Noting the rarity of quiescent galaxies without prominent bulges, we argue that a prominent bulge (and perhaps, by association, a supermassive black hole) is an important condition for quenching star formation on galactic scales over the last 10 Gyr, in qualitative agreement with the active galactic nucleus feedback paradigm.

Performance analyses of Z-source and quasi Z-source inverter for photovoltaic applications

Science.gov (United States)

Himabind, S.; Priya, T. Hari; Manjeera, Ch.

2018-04-01

This paper presents the comparative analysis of Z-source and Quasi Z-source converter for renewable energy applications. Due to the dependency of renewable energy sources on external weather conditions the output voltage, current changes accordingly which effects the performance of traditional voltage source and current source inverters connected across it. To overcome the drawbacks of VSI and CSI, Z-source and Quasi Z-source inverter (QZSI) are used, which can perform multiple tasks like ac-to-dc, dc-to-ac, ac-to-ac, dc-to-dc conversion. They can be used for both buck and boost operations, by utilizing the shoot-through zero state. The QZSI is derived from the ZSI topology, with a slight change in the impedance network and it overcomes the drawbacks of ZSI. The QZSI draws a constant current from the source when compared to ZSI. A comparative analysis is performed between Z-source and Quasi Z-source inverter, simulation is performed in MATLAB/Simulink environment.

Shugarman, L R; Fries, B E; James, M

1999-01-01

Admission cohorts from the Michigan Medicaid Home and Community-Based Waiver program and Ohio nursing homes were compared on measures of resource utilization including a modified Resource Utilization Groups (RUG-III) system, Activities of Daily Living (ADLs), and overall case mix. We found that, contrary to previous research, the two samples were remarkably similar across RUG-III categories. However, the nursing home sample was more functionally impaired on measures of ADL functioning and overall case mix. Results of this study may inform policymakers and providers of the potential for maintaining the appropriate population in the home with government-funded home care.

Z parameters

International Nuclear Information System (INIS)

Firestone, A.

1990-01-01

This paper presents results of studies of the Z Boson produced in e + e - annihilations in the DELPHI detector at the CERN LEP collider. Approximately 600 nb. -1 of useful data were collected in the first LEP running period in the last half of 1989. Results are presented on the mass and width of the Z Boson, on the partial widths of the Z decays into hadrons and into lepton pairs, on comparisons with the predictions of QCD, on the number of light neutrino generations, and on the searches for new particles. The authors find that M Z = 91.171 ± 0.030 (stat.) ± 0.030 (beam) GeV, Γ Z = 2.511 ± 0.065 GeV, Γ had. = 1741 ± 61 MeV, Γ lept. = 85.1 ± 2.9 MeV, Γ inv. = 515 ± 54 MeV, and N v = 2.97 ± 0.26 generations. The authors have set limits on the mass of the charged Higgs particle, and the authors find no evidence for new quarks, new heavy leptons, or any supersymmetric partners to the known particles. All the authors' results are consistent with the Standard Model of electroweak interactions plus QCD with exactly three generations of elementary fermions

Weather forecast bulletins on television, radio and in the newspapers in the UK now include advice about the strength of the ultraviolet (UV) radiation from the sun in terms of the Global Solar UV Index. A numerical scale of 1 to 20 is used to quote the Index for anywhere in the world and the Index addresses all ethnic groups. The Index replaces the sunburn warning system. The daily UV Index is calculated by the Met. Office from documented UV radiation levels and current atmospheric data and takes into account cloud cover forecast. Armed with the knowledge of the UV Index the public will be able to assess their personal risk of sun damage at home or abroad depending on their natural skin colour. Four categories of skin colour are identified with the Index; white skin that sunburns easily, white skin that tans readily, brown skin and black skin. A colour-coded rating from low to very high is used to identify personal risk with these skin colour categories. The Global UV Index forms an important part of the 'Sun Safety Code' developed by health organisations within the UK. (author)

The structural, mechanical, electronic and magnetic properties of the series of Heusler alloys CoFeMnZ (Z=Si, As, and Sb) have been investigated theoretically. The objective is to seek for stable half-metallic ferromagnets materials with Curie temperatures higher than room temperature. The series of CoFeMnZ (Z=Si, As and Sb) is found to exhibit half-metallic ferromagnetism with high magnetic moment and the localized moment in these magnetic compounds resides at the Mn atom. It has been observed that all our compounds have high Curie temperatures with high spin polarizations. - Highlights: • Density functional calculations for CoFeMnZ (Z=Si, As, Sb) compounds are performed. • Half-metallic ferromagnetism in CoFeMnZ (Z=Si, As, Sb) compounds is established. • The magnetic and mechanical properties for CoFeMnZ (Z=As, Sb) are studied for the first time. • The studied compounds possess high Curie temperatures with high spin polarizations.

Full Text Available The past decades has seen the rapid development of second homes in many country of the world. Therefore, secondary dwellings used for tourism-related purposes (vacation homes or second homes are a reality that becomes more pronounced and visible at both nationally and internationally level. However, the rapidity and the novelty of the phenomenon creates difficulties in terms of efficient management and suitable integration in spatial planning and urbanism plans, favoring - in a negative way - expanding of build-up areas (with second homes in a chaotic way. Since there has been no detailed investigation of second homes tourism from the perspective of informal settlements, this article follows a case-study design, with in-depth analysis of informal settlements with vacation homes found in Apuseni Nature Park. Based on long-term field research, will be exemplified 4 types of informal settlements with second homes (vacation homes identified in the case study. The aim of this paper is to critically analyse the effects of informal settlements with vacation homes on the natural environment.

Gorgulho, Bartira Mendes; Fisberg, Regina Mara; Marchioni, Dirce Maria Lobo

2013-08-01

The objective of the study is to evaluate the nutritional quality of meals consumed away from home and its association with overall diet quality. Data was obtained from 834 participants of a Health Survey in São Paulo, Brazil. Food intake was measured by a 24-hour dietary recall applied telephonically using the Automated Multiple-Pass Method. Overall dietary quality was assessed by the Brazilian Healthy Eating Index Revised (B-HEIR) and the Meal Quality Index (MQI) was used to evaluate dietary quality of the main meals. The association between the B-HEIR and the MQI was assessed by linear regression analysis. The consumption of at least one of the three main meals away from home was reported for 32% of respondents (70 adolescents, 156 adults and 40 elderly). The average MQI score of lunch consumed away from home was lower than lunch consumed at home, with higher amounts of total and saturated fats. The average score of B-HEIR was 58 points and was associated with the MQI score, energy, meal consumption location and gender. Lunch consumed away from home presented the worst quality, being higher in total and saturated fat. However, the meals consumed at home also need improvement. Copyright © 2013 Elsevier Inc.

The Impact of a 24 Month Housing First Intervention on Participants' Body Mass Index and Waist Circumference: Results from the At Home / Chez Soi Toronto Site Randomized Controlled Trial.

Directory of Open Access Journals (Sweden)

Julia Woodhall-Melnik

Full Text Available Research suggests that individuals experiencing homelessness have high rates of overweight and obesity. Unhealthy weights and homelessness are both associated with increased risk of poor health and mortality. Using longitudinal data from 575 participants at the Toronto site of the At Home/Chez Soi randomized controlled trial, we investigate the impact of receiving a Housing First intervention on the Body Mass Index (BMI and waist circumference of participants with moderate and high needs for mental health support services. The ANCOVA results indicate that the intervention resulted in no significant change in BMI or waist circumference from baseline to 24 months. The findings suggest a need for a better understanding of factors contributing to overweight, obesity, and high waist circumference in populations who have histories of housing precarity and experience low-income in tandem with other concerns such as mental illness and addictions.International Standard Randomized Control Trial Number Register ISRCTN42520374.

Incorporation of H2A.Z into the chromatin of inactive promoters has been shown to poise genes for their expression. Here we provide strong evidence that H2A.Z is incorporated into the promoter regions of estrogen receptor (ERα) target genes only upon gene induction, and that, in a cyclic pattern. Moreover, members of the human H2A.Z-depositing complex, p400, also follow the same gene recruitment kinetics as H2A.Z. Importantly, cellular depletion of H2A.Z or p400 leads to a severe defect in estrogen signaling, including loss of estrogen-specific cell proliferation. We find that incorporation of H2A.Z within TFF1 promoter chromatin allows nucleosomes to adopt preferential positions along the DNA translational axis. Finally, we provide evidence that H2A.Z is essential to allow estrogen-responsive enhancer function. Taken together, our results provide strong mechanistic insight into how H2A.Z regulates ERα-mediated gene expression and provide a novel link between H2A.Z–p400 and ERα-dependent gene regulation and enhancer function.

Extraction of Z' coupling data from Z' → jj at the LHC and SSC

International Nuclear Information System (INIS)

Rizzo, T.G.

1993-06-01

A recent analysis has shown that it may be possible at the SSC to extract information about Z' couplings via the decay Z' → jj. This technique was found to be useful for some extended electroweak models provided the Z' is relatively light. In the present paper, the authors generalize this procedure to the LHC and to Z''s which are more massive than 1 TeV
