Full Text Available In a recent article I reviewed an influential theory of sleep function, the “synaptic homeostasis hypothesis (SHY.” According to SHY, sleep renormalizes synapses that are potentiated during prior wakefulness. I concluded that while SHY is a seminal theory with important implications about sleep function and the brain, its underlying mechanisms are poorly defined. In an accompanying article, the authors of SHY responded at length. Their reply is thoughtful and provocative, but unfortunately many of the points I raised were not accurately represented or addressed. In this brief commentary, I attempt to clarify some points of confusion. I also explain why any theory of sleep function is incomplete without an understanding of the underlying cellular mechanisms.

Interviewing children is a cognitively, socially, and emotionally challenging situation, especially for young and shy children. Thus, finding methods that aid rapport and increase these children’s communication is important. The present study investigated whether children’s verbal and non-verbal communicative behavior developed differently during the rapport phase, depending on whether children were situationally shy or not, and whether the interview was conducted using the computer-assisted interview In My Shoes (IMS) or a Standard verbal interview. The sample consisted of 60 children aged 4 to 5-years-old. The results showed that for the shy children in the IMS group their talkativeness increased and their answer latency decreased including the amount of encouragement the child needed to talk, while no changes were observed for the shy children in the Standard verbal interview group. There were no significant differences in the non-verbal behavior for the shy children regardless of the interview method used. For the non-shy children, overall, the interview method did not affect either the verbal or the non-verbal outcomes. Our findings indicate that IMS can be a useful tool during the rapport-building phase with shy children as it helps these children to improve their verbal communication. PMID:28813534

Rubin, Kenneth H.; Wojslawowicz, Julie C.; Rose-Krasnor, Linda; Booth-LaForce, Cathryn; Burgess, Kim B.

2013-01-01

The mutual best friendships of shy/withdrawn and control children were examined for prevalence, stability, best friend’s characteristics, and friendship quality. Using peer nominations of shy/socially withdrawn and aggressive behaviors, two groups of children were identified from a normative sample of fifth-grade children: shy/withdrawn (n = 169) and control (nonaggressive/nonwithdrawn; n = 163). Friendship nominations, teacher reports, and friendship quality data were gathered. Results revealed that shy/withdrawn children were as likely as control children to have mutual stable best friendships. Withdrawn children’s friends were more withdrawn and victimized than were the control children’s best friends; further, similarities in social withdrawal and peer victimization were revealed for withdrawn children and their friends. Withdrawn children and their friends reported lower friendship quality than did control children. Results highlight the importance of both quantitative and qualitative measures of friendship when considering relationships as risk and/or protective factors. PMID:16485175

Taking Doctor HUANG Shi-ping as the representative, the school of Huang's golden needle is based on Chinese martial art. Golden needles are adopted as main tool. Attaching great importance on the combination of acupuncture and moxibustioin, it is also characterized with penetrating needling with long needles. Through the development of three generations, it once outshone other schools in the field of acupuncture, and became famous all over the world. It made great contribution to the development of the course of acupuncture. However, with the development of the history, the form of acupuncture education as well as apparatus were all undergone an unified reform. Therefore, Doctor HUANG Shi-ping's acupuncture school be lost gradually.

Study of nu-tau properties with the SHiP experiment

CERN Document Server

AUTHOR|(CDS)2209555

The SHiP experiment (Search for Hidden Particles) is a beam dump experiment proposed at the CERN SPS with the submission of a Technical Proposal in April 2015. SHiP aims at the observation of long lived particles very weakly coupled with ordinary matter. These particles are mostly produced in the decay of charmed hadrons whose production is therefore enhanced through the definition of the characteristics of both the beam and the proton target. This makes the SHiP experiment a Standard Model neutrino factory too, in particular of tau neutrinos produced by the Ds decay chain. My studies have mainly focused on the design of the neutrino detector and on the evaluation of its performances. The Neutrino Detector is placed in a magnetic field and it exploits the Emulsion Cloud Chamber Technology with the micrometric position resolution needed to disentangle the tau lepton decay vertex from the neutrino interaction vertex. This peculiarity, together with the high electron identification efficiency, makes this det...

Revolution, Modernity and (Trans)National Shi`i Islam: Rethinking Religious Conversion in Senegal.

Leichtman, Mara A

2009-07-01

The establishment of a Shi`i Islamic network in Senegal is one alternative to following the country's dominant Sufi orders. I examine Senegalese conversion narratives and the central role played by the Iranian Revolution, contextualizing life stories (trans)nationally in Senegal's political economy and global networks with Iran and Lebanon. Converts localize foreign religious ideologies into a 'national' Islam through the discourse that Shi`i education can bring peace and economic development to Senegal. Senegalese Shi`a perceive that proselytizing, media technologies, and Muslim networking can lead to social, cultural and perhaps even political change through translating the Iranian Revolution into a non-violent reform movement.

Tacrolimus, an immunosuppressant with narrow therapeutic window, has been used widely in transplant patients. Grapefruit juice and pomelo have been reported to increase the blood levels of tacrolimus. Zhi Ke and Zhi Shi, the ripe peels and unripe fruits of Citrus aurantium which is chemotaxonomically related to grapefruit and pomelo, are in wide use in clinical Chinese medicine. To investigate the possible interaction of these two Citrus herbs with tacrolimus, male Sprague-Dawley rats were orally given tacrolimus (1.5 mg/kg) with and without Zhi Ke and Zhi Shi decoctions in a cross-over design. Blood samples were withdrawn via cardiopuncture at specific time and quantitated by a microparticle enzyme immunoassay. In addition, to explore the mechanism of interaction, LS 180 cell line was used for the transport study of rhodamine 123, a typical substrate of P-glycoprotein (P-gp). The results showed that Zhi Shi significantly decreased the C max and AUC0−t of tacrolimus by 72.4% and 72.0%, respectively, whereas Zhi Ke did not affect tacrolimus pharmacokinetics. LS 180 cell line study indicated that Zhi Shi increased the efflux activity of P-gp, enabling us to explain the decreased oral bioavailability of tacrolimus caused by Zhi Shi. Hence, we suggest that Zhi Shi be contraindicated for transplant patients treated with tacrolimus to reduce the risk of allograft rejection. PMID:21318106

Based on the thought of Zhishen (a kind of mind regulation), Professor SHI Xue-min, academician of the China Academy of Engineering, found the Xingnao Kaiqiao (to refresh the mind and to cause resuscitation) acupuncture method, which still plays an important role in the acupuncture treatment of wind stroke nowadays. Meanwhile, great importance is attached to the comprehensive treatment of wind stroke. Danqi Piantan capsule (see text) is developed and "wind stroke unit" is set up. In recent years, Professor SHI shifts the center of research to the treatment of hypertension, the risk factor of wind stroke. Taking Renying (ST 9) as the major acupoint, acupuncture with standard measurement and manipulations is established. And good clinical effect has been obtained as well. Therefore, this article focuses on the introduction of Professor SHI Xue-min's contribution to wind stroke treatment.

Spontaneous Hemoperitoneum in Pregnancy (SHiP), an unprovoked (nontraumatic) intraperitoneal bleeding in pregnancy (up to 42days postpartum), is associated with serious adverse pregnancy outcomes. To evaluate the clinical consequences of SHiP and its association with endometriosis, a systematic review was conducted according to the PRISMA guidelines. PubMed, Embase.com and Thomson Reuters/Web of Science were searched for articles published since the latest review (August 2008) until September 2016. After assessment for eligibility, forty-four articles were included in this systematic review, describing 59 cases of SHiP. Endometriosis was present in 33/59 cases (55.9%), most often diagnosed prior to pregnancy. An association between the severity of SHiP and the stage of endometriosis could not be found. In the majority of cases, SHiP occurred in the third trimester of pregnancy (30/59 cases (50.8%)); women presented with (sub)acute abdominal pain (56/59 cases (94.9%)), hypovolemic shock (28/59 cases (47.5%)) and/or a decreased level of hemoglobin (37/59 cases (62.7%)). Signs of fetal distress were observed in 24/59 cases (40.7%). Imaging confirmed free peritoneal fluid in (37/59 cases (62.7%)). At time of surgery active bleeding was revealed in 51/56 cases (91,1%), originating from endometriotic implants (11/51 cases (21.6%)), ruptured utero-ovarian vessels (29/51 cases (56.8%)), hemorrhagic nodules of decidualized cells (1/51 cases (2.0%)) or a combination (10/51 cases (19.6%)). Median amount of hemoperitoneum was 1600mL (IQR 1000mL-2500mL). From the 45/59 cases (76.3%) in which surgical interventions was carried out during pregnancy, 7/45 cases (15.6%) reported a successful continuation of pregnancy. 5/59 cases reported recurrence of SHiP (recurrence rate 8.5%). The perinatal mortality rate was 26.9% (18/67 fetus), one maternal death was reported (1/59 cases (1,7%)). In conclusion, SHiP is a very serious complication of pregnancy, highly associated with adverse

A social surrogate is an individual who offers help and comfort in social situations or makes social events more exciting. In this study of 157 young adolescents (55% female; Mage = 13.84 years, SD = 0.75 years), the authors examined whether the linear and curvilinear associations between self-reported social surrogate use and adjustment outcomes (social problems, loneliness, anxiety symptoms, depressive symptoms) varied as a function of shyness and gender, after accounting for the effects of positive friendship quality. Regression analyses revealed that low and high levels of social surrogate use were related to greater social problems for all adolescents. In addition, shyness emerged as a moderator for several curvilinear effects. Specifically, results indicated that (a) high levels of social surrogate use were associated with greater anxiety for adolescents high in shyness; and (b) low levels of social surrogate use were associated with greater depressive symptoms for adolescents low in shyness. Findings highlight the developmental importance of specific types of relationship experiences during early adolescence and point to different implications of social surrogate use for shy and non-shy young adolescents.

SHiP stands for Search for Hidden Particles and is a recently proposed new general-purpose fixed target facility at the SPS at CERN. The main aim is the search for hidden particles predicted by different models capable of explaining dark matter, neutrino masses or the origin of baryon asymmetry in the Universe. Furthermore, a huge number of (τ-)neutrinos will be produced at such a facility making it an ideal place for ν{sub τ}-physics and thus giving the opportunity for a measurement of the τ-neutrino cross-sections or a first-time experimental evidence of the anti-τ-neutrino. This talk will give an overview of the neutrino experiment at the SHiP experiment. An emphasis is given to the reconstruction of muons from interactions in the neutrino target using a magnetic spectrometer.

Design of a detector to study associated charm production in the SHiP beam dump facility

CERN Document Server

Iuliano, Antonio; Di Crescenzo, Antonia

A dedicated experiment has been proposed by the SHiP Collaboration, to study associated charm production and decay of charmed hadrons. In this thesis we report the first design of such an experiment. This work has been carried out within the Naples neutrino group that participates to the SHiP experiment. The aim of the experiment designed in this thesis is to measure the differential associated charm production cross sections with respect to the angular and energy spectra of charmed particles. This measurement could give the acceptance of the SHiP detector for hidden particles and tau neutrinos, which are produced from charmed hadron decays.

The SHiP experiment aims at acquiring a total of 4×1019 protons on target per year. Based on demonstrated SPS performance for CNGS, the expected proton sharing between the TCC2 targets and SHiP is estimated taking into account the constraints in the super-cycle composition. We review the SPS beam parameters, the operational cycles taking into account the concurrent operation of the SPS as LHC injector and for the TCC2 experiments and the limitations on the maximum possible power dissipation and the expected sharing of the protons on target of the SHiP facility with the TCC2 targets. As a typical example this aim could be achieved while maintaining a duty cycle for the other fixed target experiments of about 18%.

Overexpression of the AtSHI gene in poinsettia, Euphorbia pulcherrima, results in compact plants.

Directory of Open Access Journals (Sweden)

Full Text Available Euphorbia pulcherrima, poinsettia, is a non-food and non-feed vegetatively propagated ornamental plant. Appropriate plant height is one of the most important traits in poinsettia production and is commonly achieved by application of chemical growth retardants. To produce compact poinsettia plants with desirable height and reduce the utilization of growth retardants, the Arabidopsis SHORT INTERNODE (AtSHI gene controlled by the cauliflower mosaic virus 35S promoter was introduced into poinsettia by Agrobacterium-mediated transformation. Three independent transgenic lines were produced and stable integration of transgene was verified by PCR and Southern blot analysis. Reduced plant height (21-52% and internode lengths (31-49% were obtained in the transgenic lines compared to control plants. This correlates positively with the AtSHI transcript levels, with the highest levels in the most dwarfed transgenic line (TL1. The indole-3-acetic acid (IAA content appeared lower (11-31% reduction in the transgenic lines compared to the wild type (WT controls, with the lowest level (31% reduction in TL1. Total internode numbers, bract numbers and bract area were significantly reduced in all transgenic lines in comparison with the WT controls. Only TL1 showed significantly lower plant diameter, total leaf area and total dry weight, whereas none of the AtSHI expressing lines showed altered timing of flower initiation, cyathia abscission or bract necrosis. This study demonstrated that introduction of the AtSHI gene into poinsettia by genetic engineering can be an effective approach in controlling plant height without negatively affecting flowering time. This can help to reduce or avoid the use of toxic growth retardants of environmental and human health concern. This is the first report that AtSHI gene was overexpressed in poinsettia and transgenic poinsettia plants with compact growth were produced.

SHI/STY Genes Affect Pre- and Post-meiotic Anther Processes in Auxin Sensing Domains in Arabidopsis

Directory of Open Access Journals (Sweden)

Leandro H. Estornell

2018-02-01

Full Text Available In flowering plants, mature sperm cells are enclosed in pollen grains formed in structures called anthers. Several cell layers surrounding the central sporogenous cells of the anther are essential for directing the developmental processes that lead to meiosis, pollen formation, and the subsequent pollen release. The specification and function of these tissues are regulated by a large number of genetic factors. Additionally, the plant hormone auxin has previously been shown to play important roles in the later phases of anther development. Using the R2D2 auxin sensor system we here show that auxin is sensed also in the early phases of anther cell layer development, suggesting that spatiotemporal regulation of auxin levels is important for early anther morphogenesis. Members of the SHI/STY transcription factor family acting as direct regulators of YUC auxin biosynthesis genes have previously been demonstrated to affect early anther patterning. Using reporter constructs we show that SHI/STY genes are dynamically active throughout anther development and their expression overlaps with those of three additional downstream targets, PAO5, EOD3 and PGL1. Characterization of anthers carrying mutations in five SHI/STY genes clearly suggests that SHI/STY transcription factors affect anther organ identity. In addition, their activity is important to repress periclinal cell divisions as well as premature entrance into programmed cell death and cell wall lignification, which directly influences the timing of anther dehiscence and the pollen viability. The SHI/STY proteins also prevent premature pollen germination suggesting that they may play a role in the induction or maintenance of pollen dormancy.

The solid-state reactions between Pd thin films and 6H-SiC substrates induced by thermal annealing, room temperature swift heavy ion (SHI) irradiation and high temperature SHI irradiation have been investigated by in situ and real-time Rutherford backscattering spectrometry (RBS) and Grazing incidence X-ray diffraction (GIXRD). At room temperature, no silicides were detected to have formed in the Pd/SiC samples. Two reaction growth zones were observed in the samples annealed in situ and analysed by real time RBS. The initial reaction growth region led to formation of Pd{sub 3}Si or (Pd{sub 2}Si + Pd{sub 4}Si) as the initial phase(s) to form at a temperature of about 450 °C. Thereafter, the reaction zone did not change until a temperature of 640 °C was attained where Pd{sub 2}Si was observed to form in the reaction zone. Kinetic analysis of the initial reaction indicates very fast reaction rates of about 1.55 × 10{sup 15} at cm{sup −2}/s and the Pd silicide formed grew linear with time. SHI irradiation of the Pd/SiC samples was performed by 167 MeV Xe{sup 26+} ions at room temperature at high fluences of 1.07 × 10{sup 14} and 4 × 10{sup 14} ions/cm{sup 2} and at 400 °C at lower fluences of 5 × 10{sup 13} ions/cm{sup 2}. The Pd/SiC interface was analysed by RBS and no SHI induced diffusion was observed for room temperature irradiations. The sample irradiated at 400 °C, SHI induced diffusion was observed to occur accompanied with the formation of Pd{sub 4}Si, Pd{sub 9}Si{sub 2} and Pd{sub 5}Si phases which were identified by GIXRD analysis.

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (search for hidden particles) experiment is intended to hunt for new physics in the largely unexplored domain of very weakly interacting particles with masses below the Fermi scale, inaccessible to the LHC experiments, and to study tau neutrino physics. The same proton beam setup can be used later to look for decays of tau-leptons with lepton flavour number non-conservation, [Formula: see text] and to search for weakly-interacting sub-GeV dark matter candidates. We discuss the evidence for physics beyond the standard model and describe interactions between new particles and four different portals-scalars, vectors, fermions or axion-like particles. We discuss motivations for different models, manifesting themselves via these interactions, and how they can be probed with the SHiP experiment and present several case studies. The prospects to search for relatively light SUSY and composite particles at SHiP are also discussed. We demonstrate that the SHiP experiment has a unique potential to discover new physics and can directly probe a number of solutions of beyond the standard model puzzles, such as neutrino masses, baryon asymmetry of the Universe, dark matter, and inflation.

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (Search for Hidden Particles) experiment is intended to hunt for new physics in the largely unexplored domain of very weakly interacting particles with masses below the Fermi scale, inaccessible to the LHC experiments, and to study tau neutrino physics. The same proton beam setup can be used later to look for decays of tau-leptons with lepton flavour number non-conservation, $\\tau\\to 3\\mu$ and to search for weakly-interacting sub-GeV dark matter candidates. We discuss the evidence for physics beyond the Standard Model and describe interactions between new particles and four different portals - scalars, vectors, fermions or axion-like particles. We discuss motivations for different models, manifesting themselves via these interactions, and how they can be probed with the SHiP experiment and present several case studies. The prospects to search for relatively light SUSY and composite particles at SHiP are also discussed....

Highlights: •The objective is to study the effect of swift heavy ion (SHI) irradiation on photoanode of DSSC for better efficiency. •This work presents the effect of SHI irradiation on various Transparent conducting oxides (TCOs). •Effects are studied in terms of conductivity and transmittance of TCOs. •ITO-PET gives best results in comparison to ITO and FTO for DSSC application under SHI irradiation. -- Abstract: Transparent conducting oxides (TCOs) are used as electrodes in dye-sensitized solar cells (DSSCs) because of their properties such as high transmittance and low resistivity. In the present work, the effects of swift heavy ion (SHI) irradiation on various types of TCOs are presented. The objective of this study is to investigate the effect of SHI on TCOs. For the present study, three different types of TCOs are considered, namely, (a) FTO (fluorine-doped tin oxide, SnO 2 :F) on a Nippon glass substrate, (b) ITO (indium tin oxide, In 2 O 3 :Sn) coated on polyethylene terephthalate (PET) on a Corning glass substrate, and (c) ITO on a Corning glass substrate. These films are irradiated with 120 MeV Ag +9 ions at fluences ranging from 3.0 × 10 11 ions/cm 2 to 3.0 × 10 13 ions/cm 2 . The structural, morphological, optical and electrical properties are studied via X-ray diffraction (XRD), atomic force microscopy (AFM), UV–Vis absorption spectroscopy and four-probe resistivity measurements, respectively. The ITO-PET electrode is found to exhibit superior conductivity and transmittance properties in comparison with the others after irradiation and, therefore, to be the most suitable for solar cell applications

[A review for a traditional Chinese medical journal Shou Shi Yi Bao].

Shou Shi Yi Bao was a journal of traditional Chinese medicine (TCM) during the period from 1935 to 1937, and was originated by Chen Huan-yun, a TCM physician in Suzhou. It is mainly to transmit the knowledge of TCM and to promote the epidemic prevention capacity of local public. The editorial characteristics and historical value of the journal were explored in initial background, staff writers, editorial policies, contents and the Editor Chen's medical ideas. Shou Shi Yi Bao was supported by many famous TCM physicians, although the journal was originated from the civil society. It was an academic TCM journal with perfect practicability for orientating to the public and highlighting the academic spirit. Chen Huan-yun was a resolute defender of TCM, and had many opinions on clinical practice and lots of scientific suggestions on TCM development. Shou Shi Yi Bao reflected the main characteristics of TCM journals in 1930s. The journal was one of the important documents to study the TCM history during the period of the Republic of China in Jiangsu Province, and it also set a stage for the struggle between TCM and Western medicine at that time. The documentary information of the journal has literature and history values in reflecting the historical process of TCM self-improvement. The success of the journal was due to not only the broken-up sectarian bias and cooperation of the TCM practitioners but also the preponderant geographic and cultural circumstances of Suzhou as well as Chen Huan-yun's profound knowledge in traditional Chinese culture and medicine.

Present parametric study investigates the characteristics of SHI induced mixed molybdenum silicide film with various ion fluences. The deposition of molybdenum thin films onto the Silicon substrate was performed using e-beam evaporation, while the heavy Au ion irradiation with energy 120 MeV was subsequently applied to form molybdenum silicide. The samples have been characterized by grazing incidence X-ray diffraction (GIXRD) for the identification of phase formation at the interface. Formation of t-Mo 5 Si 3 mixed molybdenum silicide was observed on increasing the ion irradiation fluences. (author)

Studies have shown that shy children born in the 1920s and 1950s had delayed marriage and parenthood, less stable careers, and lower occupational attainment as adults than other children. Do these effects still hold true? We examined demographic and social outcomes of children born between 1977 and 1982 in a prospective longitudinal study. We assessed shyness in childhood (age 8), adolescence (age 12-16), young adulthood (age 22-26), and adulthood (age 30-35), and derived three shyness trajectories (i.e., decreasing, increasing, and low-stable). Social and demographic outcomes for shy children who outgrew their shyness (i.e., decreasing trajectory) were indistinguishable from those who were consistently low on shyness measures. However, a shyness trajectory beginning in adolescence and increasing to adulthood was associated with poorer outcomes, similar to previous studies. These findings highlight the importance of multiple assessments in long-term longitudinal studies and the need to consider personality development within a generational context.

Full Text Available Veterinary care plays an influential role in sea turtle rehabilitation, especially in endangered species. Physiological characteristics, hematological and plasma biochemistry profiles, are useful references for clinical management in animals, especially when animals are during the convalescence period. In this study, these factors associated with sea turtle surviving were analyzed. The blood samples were collected when sea turtles remained alive, and then animals were followed up for surviving status. The results indicated that significantly negative correlation was found between buoyancy disorders (BD and sea turtle surviving (p < 0.05. Furthermore, non-surviving sea turtles had significantly higher levels of aspartate aminotranspherase (AST, creatinine kinase (CK, creatinine and uric acid (UA than surviving sea turtles (all p < 0.05. After further analysis by multiple logistic regression model, only factors of BD, creatinine and UA were included in the equation for calculating summarized health index (SHI for each individual. Through evaluation by receiver operating characteristic (ROC curve, the result indicated that the area under curve was 0.920 ± 0.037, and a cut-off SHI value of 2.5244 showed 80.0% sensitivity and 86.7% specificity in predicting survival. Therefore, the developed SHI could be a useful index to evaluate health status of sea turtles and to improve veterinary care at rehabilitation facilities.

Do temperamentally shy children process emotion differently than nonshy children? Behavioral, psychophysiological, and gender differences in reticent preschoolers.

We examined regional brain electrical activity (EEG), heart rate, and subjective responses at rest and during the presentation of videoclips designed to elicit a range of emotions (e.g., sadness, anger, happiness, fear) among a sample of healthy 4-year-old children selected for temperamental shyness. We found that shy children exhibited significantly greater relative right central EEG activation at rest and during the presentation of the fear-eliciting videoclip than nonshy children. Shy females displayed greater relative right mid-frontal EEG activation during the sad, happy, and fear videoclips than shy males who displayed greater relative left mid-frontal EEG activation. These results (1) suggest that recent frontal EEG activation/emotion models might be gender-specific and (2) appear to provide the first empirical evidence for recent theoretical notions linking the origins and maintenance of temperamental shyness in children to difficulty in regulating fear responses.

SHiP is an experiment to look for very weakly interacting particles at a new to be constructed beam-dum p facility at the CERN SPS. The SHiP Technical Proposal has been submitted to the CERN SPS Committee in April 2015. The 400 GeV/c proton beam extracted from the SPS will be dumped on a heavy target with the aim of integ rating $2\\times 10^{20}$ proton on target in five years. A detector located downstream of the target, based on a long vacuum tank followed by a spectrometer and particle identification detectors, will allow probing a variety of models with light long-lived exotic particles and masses below a few GeV/c$^2$. The main focus will be the physics of the so-called Hidden Portals, i.e. search for Dark Photons, Light scalars and pseudo-scalars, and Heavy Neutral Leptons (HNL). The sensitivity to HNL will allow for the first time to probe, in the mass range between the kaon and the charm meson mass, a coupling range for which Baryogenesis and active neutrino masses could also be explained...

The discovery of the Higgs boson has fully confirmed the Standard Model of particles and fields. Nevertheless, there are still fundamental phenomena, like the existence of dark matter and the baryon asymmetry of the Universe, which deserve an explanation that could come from the discovery of new particles. The SHiP experiment at CERN meant to search for very weakly coupled particles in the few GeV mass domain has been recently proposed. The existence of such particles, foreseen in different theoretical models beyond the Standard Model, is largely unexplored. A beam dump facility using high intensity 400 GeV protons is a copious source of such unknown particles in the GeV mass range. The beam dump is also a copious source of neutrinos and in particular it is an ideal source of tau neutrinos, the less known particle in the Standard Model. Indeed, tau anti-neutrinos have not been directly observed so far. We report the physics potential of such an experiment including the tau neutrino magnetic moment.

When people in close relationships are not prepared to listen to emotional disclosures. The role of social constraints in shy people’s functioning

Directory of Open Access Journals (Sweden)

2007-12-01

Full Text Available The following article comprises a presentation of research carried out on a group of 268 adults. The survey aimed at finding answers to questions posed about the meditative role played by social constraints in the relationship between shyness and certain aspects of emotional and social functioning. The results indicate that social constraints are a destructive factor in the everyday functioning of those facing everyday problems. Many shy people experience social constraints - people in close relationships: family, relatives, and friends react inadequately and negatively, demonstrating a lack of empathy, thus discouraging people who are shy from expressing their personal thoughts and emotions. Regression analyses, conducted in order to detect the meditative effects of social constraints, show that their destructive influence is particularly severe in the case of shy people leading to their low self-esteem, a high level of depressive symptoms and a low perception of social support.

Despite the Standard Model (SM) has been strongly confirmed by the Higgs discovery, several experimental facts are still not explained. The SHiP experiment (Search for Hidden Particles), a beam dump experiment at CERN, aims at the observation of long lived particles very weakly coupled with ordinary matter. These particles of the GeV mass scale, foreseen in many extensions of the SM, might come from the decay of charmed hadrons produced in the collision of a 400 GeV proton beam on a target. High rates of all the three active neutrinos are also expected. For the first time the properties and the cross section of the ντ will be studied thanks to a detector based on nuclear emulsions, with the micrometric resolution needed to identify the tau lepton produced in neutrino interactions. Measuring the charge of the tau daughters, will enable the first observation of the ν ̄τ and the study of its cross section.

This study was designed to determine the therapeutic efficacy and safety of the Shi-cha capsule, a Chinese herbal formula, in the treatment of patients with wind-cold type common cold. In our multi-center, prospective, double-blind, randomized, placebo-controlled, dose-escalation trial, patients with wind-cold type common cold received 0.6 g of Shi-cha capsule plus 0.6 g placebo (group A), 1.2 g of Shi-cha capsule (group B), or 1.2 g placebo (group C), three times daily for 3 days and followed up to 10 days. The primary end point was all symptom duration. The secondary end points were main symptom duration, minor symptom duration, the changes in cumulative symptom score, main symptom score, and minor symptom score 4 days after the treatment, as well as adverse events. A total of 377 patients were recruited and 360 met the inclusive criteria; 120 patients constituted each treatment group. Compared with patients in group C, patients in groups A and B had significant improvement in the all symptom duration, main symptom duration, minor symptom duration, as well as change from baseline of cumulative symptom score, main symptom score, and minor symptom score at day 4. The symptom durations and scores showed slight superiority of group B over group A, although these differences were not statistically significant. There were no differences in adverse events. The Shi-cha capsule is efficacious and safe for the treatment of patients with wind-cold type common cold. Larger trials are required to fully assess the benefits and safety of this treatment for common cold. PMID:23346193

Many theories beyond the standard model predict long lived neutral (hidden) particles. There might be a whole Hidden Sector (HS) of weakly interacting particles, which cannot be detected in existing high energy experiments. The SHiP experiment (Search for Hidden Particles) requires a high intensity beam dump, which could be realized by a new facility at the CERN SPS accelerator. New superweakly interacting particles with masses below O(10) GeV could be produced in the beam dump and detected in a general purpose Hidden Sector (HS) detector. In addition there will be a dedicated tau neutrino subdetector. I present the major requirements and technical challenges for the HS detector and discuss how the HS can be accessed through several portals: neutrino portal, scalar portal, vector portal and many more.

According to Qihai theory, academician SHI Xuemin established the acupuncture technique "controlling Qihai to regulate blood pressure" which focused on Renying (ST 9), and achieved favorable effects in clinical application. In this paper, based on the Qihai theory, from aspects of Yuan qi , Zong qi , Ying qi and Wei qi and relations among qi , blood and veins in TCM, and cardiac output, sympathetic nerve activity and blood vessels in modern medicine, the understanding on hypertension was explained. As a result, both TCM and modern medicine had consistency in the understanding of hypertension, reflecting the scientificity and practicability of this acupuncture technique. Besides, according to Qihai theory and "wind leading to vertigo" theory, academician SHI Xuemin brought forward the key pathogenesis of hypertension was "dysfunction of Qihai ", and the acupoint selected Renying (ST 9), Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3). At the same time, the operation specification of each acupoint was mainly discussed, and the references of acupoint selection was explained based on TCM theory and modern clinical research.

Tau neutrinos will be distinguished by anti-neutrinos, thus providing the first observation of the tau anti-neutrino. With muon neutrinos it will be possible to study the strangeness content of the nucleon.

Tau neutrinos will be distinguished by anti-neutrinos, thus providing the first observation of the tau anti-neutrino. With muon neutrinos it will be possible to study the strangeness content of the nucleon.

SHiP (Search for Hidden Particles) is a newly designed fixed target facility, proposed at the CERN SPS accelerator, with the aim of complementing searches for New Physics at LHC by searching for light long-lived exotic particles with masses below a few GeV/c2. The sensitivity to Heavy Neutrinos will allow for the first time probing a region of the parameter space where Baryogenesis and active neutrino masses and oscillation could also be explained. A dedicated detector, based on OPERA-like bricks, will provide the first observation of the tau anti-neutrino. Moreover, $\

Why investors shy away from coal

International Nuclear Information System (INIS)

Roling, D.A.

Why do investors shy away from coal? This may sound like a strange question given the change in ownership of many major coal companies in recent years, but the ongoing consolidation within the coal industry is quite different from any actual new investment in the industry. To begin to understand why, one must return to the early '70s, a time of low-cost, abundant energy. The price of oil was about $2-4/bbl until 1973. The price of natural gas was about 60 cents/M ft 3 , and coal was approximately $7/st. This, however, was before the first Organization of the Petroleum Exporting Countries (OPEC) shock. The price of coal declined throughout the 1980s, and continues its downward path in some markets. Many coal investments have not achieved their expected return, such as the case of a 1M st/yr mine in West Virginia, which was developed in the early '80s only to be put immediately on a care-and-maintenance basis, where it languished until it was sold in 1990. Other mines, such as the large open-pit mines in the Powder River Basin in Wyoming, never reached their targeted production rates. Some of these large mines had equipment that remained in crates for years, only later to be sold at a loss. The extent of losses on investments in coal mines is discussed

The continuous downscaling of Metal Oxide Semiconductor (MOS) devices has reached a limit with SiO_2 as a gate dielectric material. Introducing high-k dielectric materials as a replacement for the conservative SiO_2 is the only alternative to reduce the leakage current. HfO_2 is a reliable and an impending material for the wide usage as a gate dielectric in semiconductor industry. HfO_2 thin films were synthesized by RF sputtering technique. Here, we present a study of Swift Heavy Ion (SHI) irradiation with100 MeV Ag ions for studying the optical properties as well as 80 MeV Ni ions for studying the electrical properties of HfO_2/Si thin films. Rutherford Backscattering Spectrometry (RBS), Field Emission Scanning Electron Microscope (FESEM), energy-dispersive X-ray spectroscopy (EDS), profilometer and I–V (leakage current) measurements have been employed to study the SHI induced effects on both the structural, electrical and optical properties.

Full Text Available Die soldering (die sticking is a defect of metal casting in which molten metal “welds” to the metallic die mold surface during casting process. Die soldering is the result of an interface reaction between the molten aluminum and the die material. Aluminum alloy with 7 and 11% silicon and SKD 61 die steel are the most common melt and die material used in aluminum die casting. This research is done to study the morphology and the characteristics of the formed AlxFeySiz intermetallic layer during interface reaction at dipping test. The samples of as-anneal SKD 61 tool steel was dipped into the molten of Al-7%Si held at temperature 680oC and into molten Al-11%Si held at temperature 710oC with the different contact time of 10 minutes; 30 minutes; and 50 minutes. The research results showed that the interface reaction can form a compact intermetallic layer with AlxFey phase and a broken intermetallic layer with AlxFeySiz phase on the surface of SKD 61 tool steel. The increasing of the contact time by the immersion of material SKD 61 tool steel in both of molten Al-7%Si and Al-11%Si will increase the thickness of the AlxFeySiz intermetallic layer until an optimum point and then decreasing. The micro hardness of the AlxFeySiz intermetallic layer depends on the content of the iron. Increasing of the iron content in intermetallic layer will increase the micro hardness of the AlxFeySiz. This condition happened because the increasing of Fe content will cause forming of intermetallic AlxFeySiz phase becomes quicker.

2015-06-01

Transparent conducting oxides (TCOs) are used as electrodes in dye-sensitized solar cells (DSSCs) because of their properties such as high transmittance and low resistivity. In the present work, the effects of swift heavy ion (SHI) irradiation on various types of TCOs are presented. The objective of this study is to investigate the effect of SHI on TCOs. For the present study, three different types of TCOs are considered, namely, (a) FTO (fluorine-doped tin oxide, SnO2:F) on a Nippon glass substrate, (b) ITO (indium tin oxide, In2O3:Sn) coated on polyethylene terephthalate (PET) on a Corning glass substrate, and (c) ITO on a Corning glass substrate. These films are irradiated with 120 MeV Ag+9 ions at fluences ranging from 3.0 × 1011 ions/cm2 to 3.0 × 1013 ions/cm2. The structural, morphological, optical and electrical properties are studied via X-ray diffraction (XRD), atomic force microscopy (AFM), UV-Vis absorption spectroscopy and four-probe resistivity measurements, respectively. The ITO-PET electrode is found to exhibit superior conductivity and transmittance properties in comparison with the others after irradiation and, therefore, to be the most suitable for solar cell applications.

The first-ever reliability stress test on surface micromachined microengines developed at Sandia National Laboratories (SNL) has been completed. We stressed 41 microengines at 36,000 RPM and inspected the functionality at 60 RPM. We have observed an infant mortality region, a region of low failure rate (useful life), and no signs of wearout in the data. The reliability data are presented and interpreted using standard reliability methods. Failure analysis results on the stressed microengines are presented. In our effort to study the reliability of MEMS, we need to observe the failures of large numbers of parts to determine the failure modes. To facilitate testing of large numbers of micromachines. The Sandia High Volume Measurement of Micromachine Reliability (SHiMMeR) system has computer controlled positioning and the capability to inspect moving parts. The development of this parallel testing system is discussed in detail.

Selective Internal Oxidation and Severe Plastic Deformation of Multiphase Fe-Y Alloys

Science.gov (United States)

Kachur, Stephen J.

Oxide dispersion strengthened (ODS) alloys are known for their desirable mechanical properties and unique microstructures. These alloys are characterized by an even dispersion of oxide phase throughout a metallic matrix, and exhibit high strength and enhanced creep properties at elevated temperatures. This makes them ideal candidate materials for use in many structural applications, such as coal-fired power plants or in next generation nuclear reactors. Currently most often produced by mechanical alloying, a powder metallurgy based process that utilizes high energy ball milling, these alloys are difficult and costly to produce. One proposed method for forming ODS alloys without high-energy ball milling is to internally oxidize a bulk alloy before subjecting it to severe plastic deformation to induce an even oxide distribution. This work examines such a processing scheme with a focus on the internal oxidation behavior. Internal oxidation has been shown to occur orders of magnitude faster than expected in multi-phase alloys where a highly reactive oxidizable solute has negligible solubility and diffusivity in other, more-noble, phases. Commonly referred to as in situ oxidation, this accelerated oxidation process has potential for use in a processing scheme for ODS alloys. While in situ oxidation has been observed in many different alloy systems, a comprehensive study of alloy composition and microstructure has not been performed to describe the unusual oxidation rates. This work used Fe-Y binary alloys as model system to study effects of composition and microstructure. These alloys have been shown to exhibit in situ oxidation, and additionally, Y is typically introduced during mechanical alloying to form Y-rich oxides in Fe-based ODS alloys. Alloys with Y content between 1.5 and 15 wt% were prepared using a laboratory scale arc-melting furnace. These alloys were two phase mixtures of Fe and Fe17Y2. First, samples were oxidized between 600 and 800 °C for 2 to 72

Effects of Climate Change and Fisheries Bycatch on Shy Albatross (Thalassarche cauta) in Southern Australia.

Thomson, Robin B; Alderman, Rachael L; Tuck, Geoffrey N; Hobday, Alistair J

2015-01-01

The impacts of climate change on marine species are often compounded by other stressors that make direct attribution and prediction difficult. Shy albatrosses (Thalassarche cauta) breeding on Albatross Island, Tasmania, show an unusually restricted foraging range, allowing easier discrimination between the influence of non-climate stressors (fisheries bycatch) and environmental variation. Local environmental conditions (rainfall, air temperature, and sea-surface height, an indicator of upwelling) during the vulnerable chick-rearing stage, have been correlated with breeding success of shy albatrosses. We use an age-, stage- and sex-structured population model to explore potential relationships between local environmental factors and albatross breeding success while accounting for fisheries bycatch by trawl and longline fisheries. The model uses time-series of observed breeding population counts, breeding success, adult and juvenile survival rates and a bycatch mortality observation for trawl fishing to estimate fisheries catchability, environmental influence, natural mortality rate, density dependence, and productivity. Observed at-sea distributions for adult and juvenile birds were coupled with reported fishing effort to estimate vulnerability to incidental bycatch. The inclusion of rainfall, temperature and sea-surface height as explanatory variables for annual chick mortality rate was statistically significant. Global climate models predict little change in future local average rainfall, however, increases are forecast in both temperatures and upwelling, which are predicted to have detrimental and beneficial effects, respectively, on breeding success. The model shows that mitigation of at least 50% of present bycatch is required to offset losses due to future temperature changes, even if upwelling increases substantially. Our results highlight the benefits of using an integrated modeling approach, which uses available demographic as well as environmental data

In genetics, a consanguineous marriage means union between couples who are related as second cousins or closer. The present cross-sectional study was carried out in order to illustrate the prevalence and types of consanguineous marriages in the Shi'a population living in widespread territories in Lebanon including the Bekaa Valley, the south of Lebanon and the southern suburb of Beirut. Data on types of marriages were collected using a simple questionnaire. The total number of couples in the study was 1203. Consanguineous marriage was classified by the degree of relationship between couples. The overall frequency of consanguinity was found to be 28.4%, with first cousin marriages (21.3%) being the most common type followed by first cousins once removed (5.5%), then double first cousins (0.8%). The frequencies of second cousin and beyond second cousin marriages were the same at 0.4% of all the marriages. The mean inbreeding coefficient (α) was estimated at about 0.0161 for the population. There were no significant differences between the three studied territories for frequencies of different types of marriages (p>0.1), nor were there significant differences between the rural and urban areas (p>0.1).

Regional asymmetry of metabolic and antioxidant profile in the sciaenid fish shi drum (Umbrina cirrosa white muscle. Response to starvation and refeeding

Full Text Available The objective of the present study is to characterize the metabolic and antioxidant profile of white muscle of shi drum in two sites of the body, anterior dorsal (AM and posterior dorsal (PM portions. In addition, it will be analyzed the possible effect of starvation and a subsequent refeeding, with two different protocols, pair feeding and ad libitum. Activities of key enzymes of intermediary metabolism and of antioxidant enzymes, as well as lipid peroxidation, as an index of oxidative stress, were evaluated. The results indicate the existence of a regional asymmetry of the metabolic capacities of the white muscle of shi drum, which is likely related to the different contribution to swimming of the body regions examined. Starvation induces a metabolic depression that is more marked in those activities that support burst swimming in PM, while those activities supporting maintenance requirements are conserved. The greatest energy demands during starvation appear to lie in AM, which showed the highest oxidative metabolism rate. The increased use of fatty acids as energy source for AM leads to oxidative stress. A period of more than four weeks of refeeding for full restoration of metabolic capacities in AM is needed, probably related to the higher muscle mass located in this region. On the contrary, all enzyme activities in PM returned to control levels in both refeeding protocols, but pair feeding seems to be advantageous since compensatory growth has been taking place without signs of oxidative stress. This work was addressed to gain knowledge on the physiology of a promising fish species in aquaculture like shi drum. The results displayed here show how the starving and further re-feeding events could generate oxidative stress situations characterized by high lipid peroxidation levels which may influence negatively on the quality of the edible part of the fish. This study opens an interesting field on this fish species which deserves being

Full Text Available SHiP (Search for Hidden Particles is a new general purpose fixed target facility, whose Technical Proposal has been recently reviewed by the CERN SPS Committee and by the CERN Research Board. The two boards recommended that the experiment proceeds further to a Comprehensive Design phase in the context of the new CERNWorking group "Physics Beyond Colliders", aiming at presenting a CERN strategy for the European Strategy meeting of 2019. In the initial phase of SHiP, the 400 GeV proton beam extracted from the SPS will be dumped on a heavy target with the aim of integrating 2×1020 pot in 5 years. A dedicated detector, based on a long vacuum tank followed by a spectrometer and particle identification detectors, will allow probing a variety of models with light long-lived exotic particles and masses below O(10 GeV/c2. The main focus will be the physics of the so-called Hidden Portals, i.e. search for Dark Photons, Light scalars and pseudo-scalars, and Heavy Neutrinos. The sensitivity to Heavy Neutrinos will allow for the first time to probe, in the mass range between the kaon and the charm meson mass, a coupling range for which Baryogenesis and active neutrino masses could also be explained. Another dedicated detector will allow the study of neutrino cross-sections and angular distributions.

In times of war, women are likely to experience, in addition to the "normal" violence of peacetime, random cruelties perpetrated by the enemy against all members of the community. During research conducted with Palestinian refugees and Shi'i Muslims in Lebanon, women described various forms of violence and, in this article, I examine violence suffered by women in the context of conflict from three perspectives: victimization, trauma, and resistance. I argue that traumatic events have the effect of obliterating identity, but they can also strengthen the resolve to resist.

To detect nuclear explosions, waveform data from over 240 SHI stations world-wide flows into the International Data Centre (IDC) of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), located in Vienna, Austria. A complex pipeline of software applications processes this data in numerous ways to form event hypotheses. The software codebase comprises over 2 million lines of code, reflects decades of development, and is subject to frequent enhancement and revision. Since processing must run continuously and reliably, software changes are subjected to thorough testing before being put into production. To overcome the limitations and cost of manual testing, the Continuous Automated Testing System (CATS) has been created. CATS provides an isolated replica of the IDC processing environment, and is able to build and test different versions of the pipeline software directly from code repositories that are placed under strict configuration control. Test jobs are scheduled automatically when code repository commits are made. Regressions are reported. We present the CATS design choices and test methods. Particular attention is paid to how the system accommodates the individual testing of strongly interacting software components that lack test instrumentation.

A case of the rare juvenile form of Kearns-Shy syndrome with progressive external ophthalmoplegia and lid ptosis, carditis, skeletal muscle weakness, seizures, mental subnormality, short stature, EEG abnormality and deafness is presented. Electromyography revealed a myopathic pattern. Histochemical studies on quadriceps biopsy specimens showed atrophy of type II fibers and ''ragged-red fibers.'' On electron microscopy these muscle cells were seen to contain an increased amount of glycogen particles and abnormal mitochondria were increased in number and size. It is of interest that abrupt deterioration of neurological findings such as seizures, mental subnormality, speech disturbance and deafness was present in our case. Computed tomographic scanning showed progressive changes of cerebral atrophy, low density of cerebral white matter and basal ganglia calcification, which were well associated with the clinical deterioration. A review of the literature also indicated that some patients with this syndrome showed abrupt neurological deterioration in childhood. Involvement of the central nervous system in this syndrome has to be considered as the cause of sudden deterioration and death in childhood. (author)

Highlights: • N doped SiC were irradiated with 150 MeV Ag{sup 12+} (1 × 10{sup 12} to 5 × 10{sup 13} ions/cm{sup 2}). • Local disorder are analyzed by studying the LO Raman mode of the irradiated sample. • The TRPL studies provided evidence of the formation of radiative centers at 80 K. -- Abstract: In this report, the effect of disorder accumulation in Swift Heavy Ion (SHI) irradiated 6H-SiC is distinguished with respect to the irradiation temperature, viz., 80 K and 300 K. The samples were irradiated with 150 MeV Ag{sup 12+} ions with different fluences ranging from 1 × 10{sup 12} to 5 × 10{sup 13} ions/cm{sup 2}. The structural and optical properties of N-doped 6H-SiC in its pristine condition and after SHI irradiation have been studied. The changes observed by Raman spectroscopy and Time resolved photoluminescence (TRPL) spectroscopy were ascribed to the disorder accumulation in 6H-SiC. The local disorder has been analyzed by studying the LO Raman mode of the irradiated sample in comparison to the pristine sample. The TRPL studies have provided evidence of the formation of radiative centers after irradiation at 80 K.

Poly ethylene oxide (PEO) films were synthesized by solution cast method. These self-standing films were exposed with 60 MeV C{sup +5} ion and 100 MeV Ni{sup +7} ion at different fluences. SHI induced effect was investigated by employing various techniques. The crystalline size decreased upon irradiation as observed from XRD analysis. FTIR analysis reveals the decrement in the peak intensity upon irradiation. Tauc’s method was used to determine the optical band gap (E{sub g}), which shows decreasing trends with increase of fluence. The dielectric properties were investigated in the frequency range 10 Hz to 10 MHz for unirradiated and irradiated films. The dielectric constant remains same for the broad-spectrum of frequency and increases at lower frequency. The dielectric loss also moderately influence as a function of frequency due to irradiation. DSC analysis validated the results of XRD. Scanning electron microscopy (SEM) reveals that there is significant change in the surface morphology due to irradiation.

The light yield and the time resolution of different types of 3 m long scintillating bars instrumented with wavelength shifting fibres and read out by different models of silicon photomultipliers have been measured at a test beam at the T9 area at the CERN Proton Synchrotron. The results obtained with different configurations are presented. A time resolution better than 800 ps, constant along the bar length within 20%, and a light yield of 140 (70) photo-electrons are obtained for bars 3 m long, 4.5 (5) cm wide and 2 (0.7) cm thick. These results nicely match the requirements for the Muon Detector of the SHiP experiment.

This paper describes the basic ideas and the first simulation results of a new electro-magnetic calorimeter concept, named SplitCal, aimed at optimising the measurement of photon direction in fixed-target experiment configuration, with high photon detection efficiency. This calorimeter was designed for the invariant mass reconstruction of axion-like particles decaying into two photons in the mass range 200 MeV to 1 GeV for the proposed proton beam dump experiment SHiP at CERN. Preliminary results indicate that angular resolutions better than obtained by past experiments can be achieved with this design. An implementation of this concept with real technologies is under study.

The objective of this study is to assess swallowing and speech outcome after chemoradiation therapy for head and neck cancer, based on the patient-reported outcome measures Swallowing Quality of Life Questionnaire (SWAL-QOL) and Speech Handicap Index (SHI), both provided with cut-off scores. This is a cross-sectional study. Department of Otolaryngology/Head and Neck Surgery of a University Medical Center. Sixty patients, 6 months to 5 years after chemoradiation for head and neck squamous cell carcinoma. Swallowing Quality of Life Questionnaire (SWAL-QOL) and SHI, both validated in Dutch and provided with cut-off scores. Associations were tested between the outcome measures and independent variables (age, gender, tumor stage and site, and radiotherapy technique, time since treatment, comorbidity and food intake). Fifty-two patients returned the SWAL-QOL and 47 the SHI (response rate 87 and 78 %, respectively). Swallowing and speech problems were present in 79 and 55 %, respectively. Normal food intake was noticed in 45, 35 % had a soft diet and 20 % tube feeding. Patients with soft diet and tube feeding reported more swallowing problems compared to patients with normal oral intake. Tumor subsite was significantly associated with swallowing outcome (less problems in larynx/hypopharynx compared to oral/oropharynx). Radiation technique was significantly associated with psychosocial speech problems (less problems in patients treated with IMRT). Swallowing and (to a lesser extent) speech problems in daily life are frequently present after chemoradiation therapy for head and neck cancer. Future prospective studies will give more insight into the course of speech and swallowing problems after chemoradiation and into efficacy of new radiation techniques and swallowing and speech rehabilitation programs.

Taiwan, because of its location, is a flood prone region and is characterised by typhoons which brings about two-thirds to three quarters of the annual rainfall amount. Consequently, enormous flows result in rivers and entrain some fractions of the grains that constitute the riverbed. Hence, the purpose of the study is to quantify the impacts of these enormous flows on the distribution of grain size in riverbeds. The characteristics of riverbed material prior to and after the typhoon season are compared in Shi-Wen River located at southern Taiwan. These include grain size variation, bimodality, and roughness coefficient. A decrease (65%) and increase (50%) in geometric mean size of grains were observed for subsurface and surface bed material, respectively. Geometric standard deviation decreased in all sites after typhoon. Subsurface material was bimodal prior to typhoons and polymodal after. For surface material, modal class is in the gravel class, while after typhoons it shifts towards cobble class. The reduction in geometric mean resulted to a decrease in roughness coefficient by up to 30%. Finally, the relationship of Shields and Froude numbers are studied and a change in the bed form to antidunes and transition form is observed, respectively.

Full Text Available A four-month growth trial was carried out in order to evaluate performance and quality traits of juvenile shi drum fedwith two isonitrogenous and isoenergetic diets having different amounts of vegetable products (Vegetable diet vs. Controldiet. Compared to the Control diet, the Vegetable diet was formulated by increasing the replacement of fish meal (14%with soybean and cereal products, and fish oil (12% with a mixture of vegetable oil. On June, 4 groups of 225 fish (2replicates per dietary treatment were sorted according to live weight and reared in fibreglass tanks over a four- monthlong experimental period. Fish were hand fed to apparent satiety. Offered feed, growth parameters and feed efficiencywere recorded as productive performance. At the end of the trial (October biometric, chemical and reological traits wereexamined to assess fish quality. The dietary treatments showed similar productive performance. The relatively high inclusionof vegetable sources led to a significant modification of body shape, mesenteric fat and viscera weight. Among qualitytraits, Vegetable diet-fed fish demonstrated a significantly lower whole body and fillet crude protein content.Yellowness value of the cooked fillet was significantly lower in the Control diet-fed fish, whereas fillet texture was similar.The results of this research showed that shi drum is a suitable candidate for Mediterranean marine aquaculture andits dietary formulation might include at least the amount of vegetable sources used in this trial.

When analyzing data from an array of spacecraft (such as Cluster or MMS) crossing a site of magnetic reconnection, it is desirable to be able to accurately determine the orientation of the reconnection site. If the reconnection is quasi-two dimensional, there are three key directions, the direction of maximum inhomogeneity (the direction across the reconnection site), the direction of the reconnecting component of the magnetic field, and the direction of rough invariance (the "out of plane" direction). Using simulated spacecraft observations of magnetic reconnection in the geomagnetic tail, we extend our previous tests of the direction-finding method developed by Shi et al. (2005) and the method to determine the structure velocity relative to the spacecraft Vstr. These methods require data from four proximate spacecraft. We add artificial noise and calibration errors to the simulation fields, and then use the perturbed gradient of the magnetic field B and perturbed time derivative dB/dt, as described by Denton et al. (2010). Three new simulations are examined: a weakly three-dimensional, i.e., quasi-two-dimensional, MHD simulation without a guide field, a quasi-two-dimensional MHD simulation with a guide field, and a two-dimensional full dynamics kinetic simulation with inherent noise so that the apparent minimum gradient was not exactly zero, even without added artificial errors. We also examined variations of the spacecraft trajectory for the kinetic simulation. The accuracy of the directions found varied depending on the simulation and spacecraft trajectory, but all the directions could be found within about 10 for all cases. Various aspects of the method were examined, including how to choose averaging intervals and the best intervals for determining the directions and velocity. For the kinetic simulation, we also investigated in detail how the errors in the inferred gradient directions from the unmodified Shi et al. method (using the unperturbed gradient

SHiP: a new facility for searching for long-lived neutral particles and studying the tau neutrino properties

CERN Document Server

AUTHOR|(SzGeCERN)658186

2016-01-01

SHiP (Search for Hidden Particles) is a new general purpose fixed target facility, proposed at the CERN SPS accelerator. In its initial phase, the 400 GeV proton beam will be dumped on a heavy target, integrating $2\\times 10^{20}$ protons on target in 5 years. A dedicated detector located downstream of the target, based on a long vacuum tank and a spectrometer and particle identification detectors, will allow probing a variety of models with light long-lived neutral and very weakly interacting particles and masses below 10 GeV. The main focus will be the physics of the so-called Hidden Portals, i.e. search for Dark Photons, Light scalars and pseudo-scalars, and Heavy Neutrinos. The sensitivity to Heavy Neutrinos will allow for the first time to probe, in the mass range between the kaon and the charm meson mass, a coupling range for which the baryon asymmetry of the Universe could be explained. Direct detection of light and long-lived SUSY particles, such as RPV neutralinos and pseudo-Dirac gauginos could als...

Full Text Available Hyperadrenocorticism can be defined as a chronic high circulating cortisol, and is a relatively common disease in dogs when compared to cats. Of dogs with naturally occurring HAC, 80 to 85% have pituitary-dependent hyperadrenocorticism (PDH, which is an excessive secretion of ACTH by the pituitary, causing bilateral adrenal hyperplasia and excessive secretion of glucocorticoids. More than 90% of dogs with PDH have a pituitary tumor. The aim of this article is to report a case of a dog, seven years old, female, Shi Tzu, that presented with panting, polyuria/polydipsia, polyphagia, pendulous abdomen and bilateral abdominal alopecia, and intermittent weakness in the pelvic limbs. Based on laboratorial and screening tests a pituitary-dependent hyperadrenocorticism was diagnosed and treated with twice-daily trilostane, orally. In the early monitoring period, ACTH test was performed with an unusual interval (to 30 days. In this case, the starting dose didn’t show improvement in the cutaneous alterations, requiring an increase on the dosage. Hiperadrenocorticismo (HAC é uma doença relativamente comum em cães quando comparado aos gatos e pode ser definido como aumento persistente do cortisol na circulação sanguínea. Quanto ao tipo de manifestação o HAC hipófise-dependente ocorre em 80 a 85% dos casos, causando secreção excessiva de ACTH pela hipófise levando ao aumento bilateral das glândulas adrenais. Mais de 90% dos casos de HAC hipófise-dependente (em cães ocorrem devido a tumores na glândula. O objetivo deste trabalho é relatar o caso de uma cadela da raça Shi Tzu, com sete anos de idade, que apresentou respiração ofegante, poliúria/polidipsia, polifagia, abdome pendular, alopecia bilateral simétrica e fraqueza intermitente em membros pélvicos. Os exames laboratoriais de rotina associados aos testes de triagem confirmaram a suspeita de hiperadrenocorticismo hipófise dependente. O tratamento desde o início tem sido com

Full Text Available With the rise of China's status on international stage as a result of its economic development there is an increasingly audible voice of Chinese cultural nationalism. More and more educators and intellectuals are calling for the revival of Chinese traditional culture values. However, the very issues of who are the Chinese and what are traditional Chinese cultural values present a huge dilemma. The debates on a recent a TV program "General Shi Lang" consist a good case to illustrate this dilemma. Shi Lang was a general of the last days of the Ming Dynasty, but had surrendered to the Manchu Qing dynasty invaders and fought for the Machus take over Taiwan from a Chinese ruler. The debates show that the dilemma has its cause in at least three issues. First, it is not at all obvious who should be categorized as Chinese. Secondly, it is not at all obvious what Chinese cultural values are. And finally it is the issue of evaluation of traditional values against the universal claim of the values of liberal democracy.

The rejection of an application for ambulant geriatric rehabilitation (AGRV) is usually justified by the argument that non-pharmaceutical therapy prescribed by doctors accredited by social housing institutions (SHI) would suffice. The reality in healthcare during the 6 months following an application is unknown. In this study 203 patients who had made an application for AGRV in the second half of 2010 in Flensburg, Lübeck or Ratzeburg were interviewed by telephone. The survey revealed that 25.7% of the applications for AGRV had been rejected. The majority of these patients received no ambulant non-pharmaceutical therapy (e.g. physical therapy, physiotherapy, occupational therapy, speech therapy or psychological therapy), less than 20% received more than 12 therapy sessions and in most cases exclusively physiotherapy. The 141 successful AGRV applicants received additional ambulant therapies of a similar magnitude. The difference between the intensified interdisciplinary therapy offered in the AGRV and additionally and the offer to rejected applicants is substantial.

Da-Huang-Xiao-Shi decoction, consisting of Rheum officinale Baill, Mirabilitum, Phellodendron amurense Rupr. and Gardenia jasminoides Ellis, is a traditional Chinese medicine used for the treatment of jaundice. As described in "Jin Kui Yao Lue", a traditional multistep decoction of Da-Huang-Xiao-Shi decoction was required while simplified one-step decoction was used in recent repsorts. To investigate the chemical difference between the decoctions obtained by the traditional and simplified preparations, a sensitive and reliable approach of high-performance liquid chromatography coupled with diode-array detection and electrospray ionization time-of-flight mass spectrometry was established. As a result, a total of 105 compounds were detected and identified. Analysis of the chromatogram profiles of the two decoctions showed that many compounds in the decoction of simplified preparation had changed obviously compared with those in traditional preparation. The changes of constituents would be bound to cause the differences in the therapeutic effects of the two decoctions. The present study demonstrated that certain preparation methods significantly affect the holistic quality of traditional Chinese medicines and the use of a suitable preparation method is crucial for these medicines to produce special clinical curative effect. This research results elucidated the scientific basis of traditional preparation methods in Chinese medicines. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Research on sodium batteries has made a comeback because of concern regarding the limited resources and cost of lithium for Li-ion batteries. From the standpoint of electrochemistry and economics, Mn- or Fe-based layered transition metal oxides should be the most suitable cathode candidates for affordable sodium batteries. Herein, this paper reports a novel cathode material, layered Na1+x(Fey/2Niy/2Mn1-y)1-xO2 (x = 0.1-0.5), synthesized through a facile coprecipitation process combined with subsequent calcination. For such cathode material calcined at 800 °C for 20 h, the Na/Na1+x(Fey/2Niy/2Mn1-y)1-xO2 (x = 0.4) electrode exhibited a good capacity of 99.1 mAh g(-1) (cycled at 1.5-4.0 V) and capacity retention over 87% after 50 cycles. Optimization of this material would make layered transition metal oxides a strong candidate for the Na-ion battery cathode.

Assessment of benzene-induced hematotoxicity using a human-like hematopoietic lineage in NOD/Shi-scid/IL-2Rγnull mice.

Directory of Open Access Journals (Sweden)

Masayuki Takahashi

Full Text Available Despite recent advancements, it is still difficult to evaluate in vivo responses to toxicants in humans. Development of a system that can mimic the in vivo responses of human cells will enable more accurate health risk assessments. A surrogate human hematopoietic lineage can be established in NOD/Shi-scid/IL-2Rγ(null (NOG mice by transplanting human hematopoietic stem/progenitor cells (Hu-NOG mice. Here, we first evaluated the toxic response of human-like hematopoietic lineage in NOG mice to a representative toxic agent, benzene. Flow cytometric analysis showed that benzene caused a significant decrease in the number of human hematopoietic stem/progenitor cells in the bone marrow and the number of human leukocytes in the peripheral blood and hematopoietic organs. Next, we established chimeric mice by transplanting C57BL/6 mouse-derived bone marrow cells into NOG mice (Mo-NOG mice. A comparison of the degree of benzene-induced hematotoxicity in donor-derived hematopoietic lineage cells within Mo-NOG mice indicated that the toxic response of Hu-NOG mice reflected interspecies differences in susceptibilities to benzene. Responses to the toxic effects of benzene were greater in lymphoid cells than in myeloid cells in Mo-NOG and Hu-NOG mice. These findings suggested that Hu-NOG mice may be a powerful in vivo tool for assessing hematotoxicity in humans, while accounting for interspecies differences.

The herbal decoction is a complex dispersion system containing solutes, colloid, aggregates, emulsions and precipitates. In which phase bioactive phytochemicals are dispersed determines their delivery, action and metabolism. This study took ephedrine, a well-studied and widely used phytochemical, as an example to elucidate its exact distribution in the phases of Ma-Xing-Shi-Gan-Tang decoction (MXSGT), which is an Ephedra sinica Stapf. containing traditional Chinese medicinal formula, and the biological meaning of this distribution correspondingly. It may provide an important update to the safety and efficacy assessment of the herbal decoction and its active phytochemicals. In this study, the decoction was fractionated with size-exclusion chromatography coupled with multi-angle laser light scattering detector. The morphology of fractionated nanoparticles was observed with AFM and SEM. The bioactivities of the decoction, the ephedrine alkaloids loaded NPs (prepared by chromatography isolation) and the synthetic ephedrine were assessed by cell proliferation tests using five cell lines, namely Caco-2, L-02, Hep-G2, NR-8383, and Hela-229. Nanoparticles with radii of gyration ranged from 50 to 150 nm were isolated, in spherical shape. Further analysis of nanoparticles on the subsequent reversed phase chromatography revealed that the majority of ephedrine (99.7%) and pseudoephedrine (95.5%) were associated with these nanoparticles, rather than dispersed freely in the real solution. The addition of both the herbal decoction and the separated ephedrine-loaded nanoparticles reserved higher cell viability/proliferation than that of the sole synthetic ephedrine among the Caco-2, L-02, Hep-G2, and NR-8383 cells. In contrast, the nanoparticles reduced the proliferating power of ephedrine on Hela-229 cells. In general, the ephedrine-loaded NPs conducted the intermediate influences on the cell viability, in either way. The colloidal nanoparticles were separated from the decoction

Full Text Available In the 11th century in China, there was an unusual moment in which a number of philosophers, later associated with the Daoxue—or Neo-Confucian—school, confronted what they perceived as a long-standing sense of disjunction between inner, subjective reality and the structured patterns of the cosmos. One way they sought to overcome this disjunction was by positing new theories of the cosmos that focused on the underlying, shared reality behind the myriad differentiations of phenomena. A potential tension was born that affected how thinkers understood the relationship between wen 文 (writing, literature, culture and Dao 道 (the cosmic process, the ultimate reality, the normative path. Some thinkers, like Zhou Dunyi 周敦頤 (1017–1073, believed that wen was simply a vehicle for carrying the Dao, and was thus, implicitly, dispensable. This idea was met with resistance from one of the leading intellectual figures of the time—the philosopher, poet and statesman Su Shi 蘇軾 (1037–1101. While some of Su’s contemporaries, in their attempts to demonstrate that the world was real, and that truth was knowable, downplayed the role of individual experience and perception, Su stressed the necessity of subjective, individual experience as giving access, and concrete expression, to Dao. Su’s philosophical project came in the form of defending the enterprise of wen—writing as a creative, individual endeavor—and asserting that the quest for unity with the Dao could only be realized through direct, personal engagement in wen and other forms of meaningful practice. Through his philosophy of wen, Su sought to show that the search for truth, meaning and order did not—and could not—be achieved by transcending subjective experience. Instead, it had to be carried out at the point of encounter between self and the world, in the realm of practice.

Highlights: • Extensive survey formation energies Frenkel pairs and electronic stopping thresholds. • Correlation: track formation thresholds and the energies for Frenkel pair formation. • Formation energies Frenkel pairs discussed in relation to the cumulative mechanisms. • Amorphous track formation mechanisms: defect accumulation models versus melting. • Advantages cumulative models to deal with new hot topics: nuclear-electronic synergy. - Abstract: An extensive survey for the formation energies of Frenkel pairs, as representative candidates for radiation-induced point defects, is presented and discussed in relation to the cumulative mechanisms (CM) of track formation in dielectric materials under swift heavy ion (SHI) irradiation. These mechanisms rely on the generation and accumulation of point defects during irradiation followed by collapse of the lattice once a threshold defect concentration is reached. The physical basis of those approaches has been discussed by Fecht as a defect-assisted transition to an amorphous phase. Although a first quantitative analysis of the CM model was previously performed for LiNbO{sub 3} crystals, we have, here, adopted a broader phenomenological approach. It explores the correlation between track formation thresholds and the energies for Frenkel pair formation for a broad range of materials. It is concluded that the threshold stopping powers can be roughly scaled with the energies required to generate a critical Frenkel pair concentration in the order of a few percent of the total atomic content. Finally, a comparison with the predictions of the thermal spike model is discussed within the analytical Szenes approximation.

Alkaline phosphatase conjugated magnetic microspheres were synthesized via amide reaction, and employed as an effective adsorbent in affinity selection of binding ligands followed by UHPLC-Q-TOF/MS analysis. The analytical validity of the developed approach was evaluated under optimized conditions and the following figures of merit were obtained: linearity, 0.01-0.5 g L -1 with good determination coefficients (R 2  = 0.9992); limits of detection (LODs), 0.003 g L -1 ; and limits of quantitation (LOQ), 0.01 g L -1 . The precision (RSD%) of the proposed affinity selection approach was studied based on intra-day (0.8%) and inter-day (1.3%) precisions. Finally, the adsorbent was successfully applied to identification of binding ligands in Li-Dan-Hua-Shi pills and good recoveries were obtained in the range from 96.9 to 99.4% (RSDs 1.6-3.0%).

Background.: Supplemental health insurances (SHI) cover 38% of the Danish population. SHI can give faster access to, and additional treatment from, private health providers. However, this is contingent on a referral from the general practitioner (GP), further complicating clinical decision...... to 3321 GPs focusing on three issues: (i) Attitudes towards the public health care system. (ii) Perceptions of the impact of SHI. (iii) Experiences with patients holding SHIs. Results.: The response rate was 64%. Overall, GPs found that SHIs contribute to inequality (83%) and overtreatment (90%). However...... a majority of GPs associate SHI with overtreatment and inequality in health, many GPs feel under pressure to refer patients holding SHI for treatments or examinations that are not medically warranted. Some GPs even refer these patients without further examination or questioning. Insistent SHI patients may...

2009-05-01

To clarify the relationship between social phobia and shyness, this study examined the characteristics of highly shy persons with social phobia, highly shy persons without social phobia, and non-shy persons. Those with social phobia reported more symptomatology, more functional impairment, and a lower quality of life than those without social phobia. About one-third of the highly shy without social phobia reported no social fears, highlighting heterogeneity of the shy. The social phobia group reported similar levels of anxiety as the shy without social phobia during analogue conversation tasks, but they reported more anxiety during a speech task. The social phobia group performed less effectively across tasks than those without social phobia. All groups' perceptions of anxiety and effectiveness during behavioral tasks were consistent with ratings of independent observers. None of the groups differed on psychophysiological measures. Results are discussed in the context of theoretical models of social phobia.

[The significance of a large number of health insurance funds and fusions for health services research with statutory health insurance data in Germany - experiences of the lidA study].

Science.gov (United States)

March, S; Powietzka, J; Stallmann, C; Swart, E

2015-02-01

Since 1970 the health insurance system in Germany has shrunk by more than 90% to 132 statutory health insurance funds (SHI) at present. For studies using data from different SHI, this development means a reduction of contacts and a higher workload when requesting data. The latter is due to the fact that fusions bind resources in the health insurance funds. In order to avoid selection in studies among the insured, all SHI must be contacted. Additionally, 15 controlling institutions on the state and national level have to agree as determined in § 75 of the German Social Code number 10. The lidA study - a German cohort study on work, age and health intends to link primary and secondary data from all SHI of those insured who have given their agreement for participation. Since the beginning of the study in 2009 the number of SHI has been reduced by 70. Of the 6 585 interviews in 2011 approximately half of the interviewees agreed in written form that their individual health insurance data can be linked. This portion of the insured is dispersed among 95 SHI. At this point, 11 contracts with SHI are realised (approximately 50% of the insured) and 8 data controlling authorities have been contacted. The problems involved in the fusion of SHI and its meaning for research are explained in this article. The fusion of SHI makes sense for the long term. It will lead to a reduction of contacts and contracts that researchers have to establish in order to analyse the data. Therefore, this article also discusses the alternative of creating a meta-data set of all the data from the different SHI combined. © Georg Thieme Verlag KG Stuttgart · New York.

We investigated whether stone heterogeneity index (SHI), which a proxy of such variations, was defined as the standard deviation of a Hounsfield unit (HU) on non-contrast computed tomography (NCCT), can be a novel predictor for shock-wave lithotripsy (SWL) outcomes in patients with ureteral stones. Medical records were obtained from the consecutive database of 1,519 patients who underwent the first session of SWL for urinary stones between 2005 and 2013. Ultimately, 604 patients with radiopaque ureteral stones were eligible for this study. Stone related variables including stone size, mean stone density (MSD), skin-to-stone distance, and SHI were obtained on NCCT. Patients were classified into the low and high SHI groups using mean SHI and compared. One-session success rate in the high SHI group was better than in the low SHI group (74.3% vs. 63.9%, P = 0.008). Multivariate logistic regression analyses revealed that smaller stone size (OR 0.889, 95% CI: 0.841-0.937, P < 0.001), lower MSD (OR 0.995, 95% CI: 0.994-0.996, P < 0.001), and higher SHI (OR 1.011, 95% CI: 1.008-1.014, P < 0.001) were independent predictors of one-session success. The radiologic heterogeneity of urinary stones or SHI was an independent predictor for SWL success in patients with ureteral calculi and a useful clinical parameter for stone fragility.

Magnetic studies of Fe-Y compositionally modulated thin films

International Nuclear Information System (INIS)

Badia, F.; Ferrater, C.; Lousa, A.; Martinez, B.; Labarta, A.; Tejada, J.

1990-01-01

Compositionally modulated thin films of Y/Fe have been studied by using SQUID magnetometry. Samples were grown by electron-beam evaporation onto Kapton substrates. In the low applied field regime, the samples show irreversible behavior when they are submitted to ZFC-FC magnetization processes, increasing the irreversibility zone as the thickness of the Fe layers increases. In the high applied magnetic field regime (H≥10 000 Oe), samples show ferromagnetic behavior. The temperature dependence of the saturation magnetization has been studied, and it was found that both spin-wave excitations and Stoner excitations occur at temperatures higher than 40 K, and a marked deviation from the T 3/2 law was noted below 30 K

This study evaluates the ability of users to self-install a smart home in a box (SHiB) intended for use by a senior population. SHiB is a ubiquitous system, developed by the Washington State University Center for Advanced Studies in Adaptive Systems (CASAS). Participants involved in this study are from the greater Palouse region of Washington State, and there are 13 participants in the study with an average age of 69.23. The SHiB package, which included several different types of components to collect and transmit sensor data, was given to participants to self-install. After installation of the SHiB, the participants were visited by researchers for a check of the installation. The researchers evaluated how well the sensors were installed and asked the resident questions about the installation process to help improve the SHiB design. The results indicate strengths and weaknesses of the SHiB design. Indoor motion tracking sensors are installed with high success rate, low installation success rate was found for door sensors and setting up the Internet server.

Applying dam height-storage curve to geomorphic features analysis within virtual geographic environment: a case study of the Hong-Shi-Mao watershed

2005-10-01

There are generally two kinds of approaches to studying geomorphic features in terms of the quantification level and difference of major considerations. One is the earlier qualitative characterization, and the other is the 2-dimension measurement that includes section pattern and projection pattern. With the development of geo-information technology, especially the 3-D geo-visualization and virtual geographic environments (VGE), 3-dimension measurement and dynamic interactive between users and geo-data/geo-graphics can be developed to understand geomorphic features deeply, and to benefit to the effective applications of such features for geographic projects like dam construction. Storage-elevation curve is very useful for site selection of projects and flood dispatching in water conservancy region, but it is just a tool querying one value from the other one. In fact, storage-elevation curve can represent comprehensively the geomorphic features including vertical section, cross section of the stream and the landform nearby. In this paper, we use quadratic regression equation shaped like y = ax2 + bx + c and the DEM data of Hong-Shi-Mao watershed, Zi Chang County, ShaanXi Province, China to find out the relationship between the coefficients of the equation and the geomorphic features based on VGE platform. It's exciting that the coefficient "a" appear to be correlative strongly with the stream scale, and the coefficient "b" may give an index to the valley shape. In the end, we use a sub-basin named Hao-Jia-Gou of the watershed as an application. The result of correlative research about quadratic regression equation and geomorphic features can save computing and improve the efficiency in silt dam systems planning.

[Use of routine data from statutory health insurances for federal health monitoring purposes].

Science.gov (United States)

Ohlmeier, C; Frick, J; Prütz, F; Lampert, T; Ziese, T; Mikolajczyk, R; Garbe, E

2014-04-01

Federal health monitoring deals with the state of health and the health-related behavior of populations and is used to inform politics. To date, the routine data from statutory health insurances (SHI) have rarely been used for federal health monitoring purposes. SHI routine data enable analyses of disease frequency, risk factors, the course of the disease, the utilization of medical services, and mortality rates. The advantages offered by SHI routine data regarding federal health monitoring are the intersectoral perspective and the nearly complete absence of recall and selection bias in the respective population. Further, the large sample sizes and the continuous collection of the data allow reliable descriptions of the state of health of the insurants, even in cases of multiple stratification. These advantages have to be weighed against disadvantages linked to the claims nature of the data and the high administrative hurdles when requesting the use of SHI routine data. Particularly in view of the improved availability of data from all SHI insurants for research institutions in the context of the "health-care structure law", SHI routine data are an interesting data source for federal health monitoring purposes.

Syria, though allied with Tehran, seeks to manage Hizbollah's freedom of action in Lebanon and is eyed cautiously in Damascus. Hizbollah has managed to maintain independence from these Syrian efforts because of both Lebanese Shi'a religious élan and the protection given Hizbollah by its Shi'a allies in Iran.

Discrimination in waiting times by insurance type and financial soundness of German acute care hospitals.

Science.gov (United States)

Schwierz, Christoph; Wübker, Achim; Wübker, Ansgar; Kuchinke, Björn A

2011-10-01

This paper shows that patients with private health insurance (PHI) are being offered significantly shorter waiting times than patients with statutory health insurance (SHI) in German acute hospital care. This behavior may be driven by the higher expected profitability of PHI relative to SHI holders. Further, we find that hospitals offering private insurees shorter waiting times when compared with SHI holders have a significantly better financial performance than those abstaining from or with less discrimination.

Sequential and joint hydrogeophysical inversion using a field-scale groundwater model with ERT and TDEM data

Directory of Open Access Journals (Sweden)

D. Herckenrath

2013-10-01

Full Text Available Increasingly, ground-based and airborne geophysical data sets are used to inform groundwater models. Recent research focuses on establishing coupling relationships between geophysical and groundwater parameters. To fully exploit such information, this paper presents and compares different hydrogeophysical inversion approaches to inform a field-scale groundwater model with time domain electromagnetic (TDEM and electrical resistivity tomography (ERT data. In a sequential hydrogeophysical inversion (SHI a groundwater model is calibrated with geophysical data by coupling groundwater model parameters with the inverted geophysical models. We subsequently compare the SHI with a joint hydrogeophysical inversion (JHI. In the JHI, a geophysical model is simultaneously inverted with a groundwater model by coupling the groundwater and geophysical parameters to explicitly account for an established petrophysical relationship and its accuracy. Simulations for a synthetic groundwater model and TDEM data showed improved estimates for groundwater model parameters that were coupled to relatively well-resolved geophysical parameters when employing a high-quality petrophysical relationship. Compared to a SHI these improvements were insignificant and geophysical parameter estimates became slightly worse. When employing a low-quality petrophysical relationship, groundwater model parameters improved less for both the SHI and JHI, where the SHI performed relatively better. When comparing a SHI and JHI for a real-world groundwater model and ERT data, differences in parameter estimates were small. For both cases investigated in this paper, the SHI seems favorable, taking into account parameter error, data fit and the complexity of implementing a JHI in combination with its larger computational burden.

Complete genome sequence of Shigella flexneri 5b and comparison with Shigella flexneri 2a

2006-07-01

Full Text Available Abstract Background Shigella bacteria cause dysentery, which remains a significant threat to public health. Shigella flexneri is the most common species in both developing and developed countries. Five Shigella genomes have been sequenced, revealing dynamic and diverse features. To investigate the intra-species diversity of S. flexneri genomes further, we have sequenced the complete genome of S. flexneri 5b strain 8401 (abbreviated Sf8401 and compared it with S. flexneri 2a (Sf301. Results The Sf8401 chromosome is 4.5-Mb in size, a little smaller than that of Sf301, mainly because the former lacks the SHI-1 pathogenicity island (PAI. Compared with Sf301, there are 6 inversions and one translocation in Sf8401, which are probably mediated by insertion sequences (IS. There are clear differences in the known PAIs between these two genomes. The bacteriophage SfV segment remaining in SHI-O of Sf8401 is clearly larger than the remnants of bacteriophage SfII in Sf301. SHI-1 is absent from Sf8401 but a specific related protein is found next to the pheV locus. SHI-2 is involved in one intra-replichore inversion near the origin of replication, which may change the expression of iut/iuc genes. Moreover, genes related to the glycine-betaine biosynthesis pathway are present only in Sf8401 among the known Shigella genomes. Conclusion Our data show that the two S. flexneri genomes are very similar, which suggests a high level of structural and functional conservation between the two serotypes. The differences reflect different selection pressures during evolution. The ancestor of S. flexneri probably acquired SHI-1 and SHI-2 before SHI-O was integrated and the serotypes diverged. SHI-1 was subsequently deleted from the S. flexneri 5b genome by recombination, but stabilized in the S. flexneri 2a genome.

While megavoltage cone-beam computed tomography (CBCT) using an electronic portal imaging device (EPID) provides many advantages over kilovoltage (kV) CBCT, clinical adoption is limited by its high doses. Multi-layer imager (MLI) EPIDs increase DQE(0) while maintaining high resolution. However, even well-designed, high-performance MLIs suffer from increased electronic noise from each readout, degrading low-dose image quality. To improve low-dose performance, shift-and-bin addition (ShiBA) imaging is proposed, leveraging the unique architecture of the MLI. ShiBA combines hardware readout-binning and super-resolution concepts, reducing electronic noise while maintaining native image sampling. The imaging performance of full-resolution (FR); standard, aligned binned (BIN); and ShiBA images in terms of noise power spectrum (NPS), electronic NPS, modulation transfer function (MTF), and the ideal observer signal-to-noise ratio (SNR)—the detectability index (d‧)—are compared. The FR 4-layer readout of the prototype MLI exhibits an electronic NPS magnitude 6-times higher than a state-of-the-art single layer (SLI) EPID. Although the MLI is built on the same readout platform as the SLI, with each layer exhibiting equivalent electronic noise, the multi-stage readout of the MLI results in electronic noise 50% higher than simple summation. Electronic noise is mitigated in both BIN and ShiBA imaging, reducing its total by ~12 times. ShiBA further reduces the NPS, effectively upsampling the image, resulting in a multiplication by a sinc2 function. Normalized NPS show that neither ShiBA nor BIN otherwise affects image noise. The LSF shows that ShiBA removes the pixilation artifact of BIN images and mitigates the effect of detector shift, but does not quantifiably improve the MTF. ShiBA provides a pre-sampled representation of the images, mitigating phase dependence. Hardware binning strategies lower the quantum noise floor, with 2  ×  2 implementation reducing the

The current study evaluated the utility of the self-harm inventory (SHI) as a proxy for and screening measure of borderline personality disorder (BPD) using several diagnostic and statistical manual of mental disorders (DSM)-based BPD measures as criteria. We used a sample of 145 psychiatric inpatients, who completed the SHI and a series of well-validated, DSM-based self-report measures of BPD. Using a series of latent trait and latent class analyses, we found that the SHI was substantially associated with a latent construct representing BPD, as well as differentiated latent classes of 'high' vs. 'low' BPD, with good accuracy. The SHI can serve as proxy for and a good screening measure for BPD, but future research needs to replicate these findings using structured interview-based measurement of BPD.

Elasticity of superhydrous phase B at the mantle temperature and pressure: Implications for 800-km discontinuity and water flow into lower mantle

Science.gov (United States)

Yang, D.; Wang, W.; Wu, Z.

2017-12-01

Plate subduction can transport the water to the Earth's interior by forming hydrous phases and water can exert important effects on global dynamics and many processes within the deep Earth. Superhydrous phase B (ShyB), as an important candidate for transporting water into the mantle transition zone and lower mantle, is stable up to 31 GPa and will decompose into bridgmanite, periclase and water at a depth of 800 km [Komabayashi and Omori, 2006]. The decomposition of ShyB may be related to the seismic discontinuity at the depth of 800 km in Western-Pacific Subduction Zones [Liu et al., 2016; Porritt and Yoshioka, 2016]. The detail discussions on this topic require the elasticity of ShyB at the P-T conditions of the transition zone and lower mantle. In this contribution, we obtained the thermal elasticity of ShyB using first-principles calculations. ShyB shows a very low velocity and density compared to the bridgmanite and periclase, the major minerals in the lower mantle. The accumulation of ShyB will generate the low-velocity anomaly in the uppermost lower mantle. The dehydration of ShyB will cause the Vp, Vs, and density increase by 7.5%, 15.0% and 12%, respectively. It means that a slab with 10% ShyB could cause an impedance contrast of 2.7% at a depth of 800 km for shear wave. Furthermore, the released waters by the dehydration of ShyB probably migrate upward and promote the partial melt to reduce the sound velocity at shallower depth, which can further explain the low-velocity zones just above 800-km discontinuity in Western-Pacific Subduction Zones [Liu et al., 2016].

The Government of Swaziland decided to explore the feasibility of social health insurance (SHI) in order to enhance universal access to health services. We assess the financial feasibility of a possible SHI scheme in Swaziland. The SHI scenario presented is one that mobilises resources additional to the maintained Ministry of Health and Social Welfare (MOHSW) budget. It is designed to increase prepayment, enhance overall health financing equity, finance quality improvements in health care, and eventually cover the entire population. The financial feasibility assessment consists of calculating and projecting revenues and expenditures of the SHI scheme from 2008 to 2018. SimIns, a health insurance simulation software, was used. Quantitative data from government and other sources and qualitative data from discussions with health financing stakeholders were gathered. Policy assumptions were jointly developed with and agreed upon by a MOHSW team. SHI would take up an increasing proportion of total health expenditure over the simulation period and become the dominant health financing mechanism. In principle, and on the basis of the assumed policy variables, universal coverage could be reached within 6 years through the implementation of an SHI scheme based on a mix of contributory and tax financing. Contribution rates for formal sector employees would amount to 7% of salaries and the Ministry of Health and Social Welfare budget would need to be maintained. Government health expenditure including social health insurance would increase from 6% in 2008 to 11% in 2018.

Micro-Raman studies of swift heavy ion irradiation induced structural and conformational changes in polyaniline nanofibers

Polyaniline (PAni) nanofibers doped with camphor sulfonic acid have been irradiated with 90 MeV O{sup 7+} ions at different fluences (3 x 10{sup 10}-1 x 10{sup 12} ions/cm{sup 2}) using a 15UD Pelletron accelerator under ultra-high vacuum. XRD studies reveal a decrease in the domain length and an increase in the strain upon SHI irradiation. The increase in d-spacing corresponding to the (1 0 0) reflection of PAni nanofibers with increasing irradiation fluence has been attributed to the increase in the tilt angle of the chains with respect to the (a, b) basal plane of PAni. Decrease in the integral intensity upon SHI irradiation indicates amorphization of the material. Micro-Raman ({mu}R) studies confirm amorphization of the PAni nanofibers and also show that the PAni nanofibers get de-doped upon SHI irradiation. {mu}R spectroscopy also reveals a benzenoid to quinoid transition in the PAni chain upon SHI irradiation. TEM results show that the size of PAni nanofibers decreases with the increase in irradiation fluence, which has been attributed to the fragmentation of PAni nanofibers in the core of amorphized tracks caused by SHI irradiation.

Social Health Inequalities and eHealth: A Literature Review With Qualitative Synthesis of Theoretical and Empirical Studies.

eHealth is developing rapidly and brings with it a promise to reduce social health inequalities (SHIs). Yet, it appears that it also has the potential to increase them. The general objective of this review was to set out how to ensure that eHealth contributes to reducing SHIs rather than exacerbating them. This review has three objectives: (1) identifying characteristics of people at risk of experiencing social inequality in health; (2) determining the possibilities of developing eHealth tools that avoid increasing SHI; and (3) modeling the process of using an eHealth tool by people vulnerable to SHI. Following the EPPI approach (Evidence for Policy and Practice of Information of the Institute of Education at the University of London), two databases were searched for the terms SHIs and eHealth and their derivatives in titles and abstracts. Qualitative, quantitative, and mixed articles were included and evaluated. The software NVivo (QSR International) was employed to extract the data and allow for a metasynthesis of the data. Of the 73 articles retained, 10 were theoretical, 7 were from reviews, and 56 were based on empirical studies. Of the latter, 40 used a quantitative approach, 8 used a qualitative approach, 4 used mixed methods approach, and only 4 were based on participatory research-action approach. The digital divide in eHealth is a serious barrier and contributes greatly to SHI. Ethnicity and low income are the most commonly used characteristics to identify people at risk of SHI. The most promising actions for reducing SHI via eHealth are to aim for universal access to the tool of eHealth, become aware of users' literacy level, create eHealth tools that respect the cultural attributes of future users, and encourage the participation of people at risk of SHI. eHealth has the potential to widen the gulf between those at risk of SHI and the rest of the population. The widespread expansion of eHealth technologies calls for rigorous consideration of

From scheme to system: social health insurance funds and the transformation of health financing in Kyrgyzstan and Moldova.

The aim of the paper is to bring evidence and lessons from two low- and middle-income countries (LMIs) of the former USSR into the global debate on health financing in poor countries. In particular, we analyze the introduction of social health insurance (SHI) in Kyrgyzstan and Moldova. To some extent, the intent of SHI introduction in these countries was similar to that in LMIs elsewhere: increase prepaid revenues for health and incorporate the entire population into the new system. But the approach taken to universality was different. In particular, the SHI fund in each country was used as the key instrument in a comprehensive reform of the health financing system, with the new revenues from payroll taxation used in an explicitly complementary manner to general budget revenues. From a functional perspective, the reforms in these countries involved not only the introduction of a new source of funds, but also the centralization of pooling, a shift from input- to output-based provider payment methods, specification of a benefit package, and greater autonomy for public sector health care providers. Hence, their reforms were not simply the introduction of an SHI scheme, but rather the use of an SHI fund as an instrument to transform the entire system of health financing. The study uses administrative and household data to demonstrate the impact of the reforms on regional inequality and household financial burden. The approach used in these two countries led to improved equity in the geographic distribution of government health spending, improved financial protection, and reduced informal payments. The comprehensive approach taken to reform in these two countries, and particularly the redirection of general budget revenues to the new SHI funds, explain much of the success that was achieved. This experience offers potentially useful lessons for LMIs elsewhere in the world, and for shifting the global debate away from what we see as a false dichotomy between SHI and

Dynamics of social health insurance development: examining the determinants of Chinese basic health insurance coverage with panel data.

Social health insurance (SHI) is gaining popularity in many developing countries, but there are few systematic empirical studies on the dynamics of SHI development. This study investigates the determinants of coverage of the Basic Healthcare Insurance for Urban Employees (BHI) in China. Using a panel database ranging from 1999 to 2007, the study finds that: (1) economic development plays a valuable role in BHI development; (2) strong financial capacity and administrative capacity in the government contributes to BHI progress; (3) higher trade union density is closely related to more rapid BHI expansion; and (4) taxation agencies are better at collecting SHI premiums. These findings provide evidence-based lessons for new and ongoing SHI programs. In addition, this article aims to make a more general contribution to the study of social policy development by expanding the scope of current theories on social policy development.

The influence of shyness on children's test performance.

Research has shown that shy children differ from their peers not only in their use of language in routine social encounters but also in formal assessments of their language development, including psychometric tests of vocabulary. There has been little examination of factors contributing to these individual differences. To investigate cognitive-competence and social anxiety interpretations of differences in children's performance on tests of vocabulary. To examine the performance of shy and less shy children under different conditions of test administration, individually with an examiner or among their peers within the familiar classroom setting. The sample consisted of 240 Year 5 pupils (122 male, 118 female) from 24 primary schools. Shy and less shy children, identified by teacher nomination and checklist ratings, completed vocabulary and mental arithmetic tests in one of three conditions, in a between-subjects design. The conditions varied individual and group administration, and oral and written responses. The conditions of test administration influenced the vocabulary test performance of shy children. They performed significantly more poorly than their peers in the two face-to-face conditions but not in the group test condition. A comparable trend for the arithmetic test was not statistically significant. Across the sample as a whole, shyness correlated significantly with test scores. Shyness does influence children's cognitive test performance and its impact is larger when children are tested face-to-face rather than in a more anonymous group setting. The results are of significance for theories of shyness and have implications for the assessment of schoolchildren.

This study set out to examine whether shyness, an aversion to novelty and unfamiliar social situations, can affect the processes that underlie early word learning. Twenty-four-month-old children (n =32) were presented with sets of one novel and two familiar objects, and it was found that shyer children were less likely to select a novel object as the referent of a novel label. Furthermore, not-shy children then showed evidence of retaining these novel mappings, but shy children did not. These findings suggest that shy children's aversion to novelty and to the unfamiliar context can impact on their word learning.

Subclinical hyperthyroidism (SHy), the mildest form of hyperthyroidism, is diagnosed in patients having a persistently low or undetectable serum concentration of thyroid-stimulating hormone (TSH) with normal free T4 and T3 concentrations. Although overt hyperthyroidism is associated with an increased risk of adverse cardiovascular outcomes, the cardiovascular risk of SHy is controversial. Multiple studies have demonstrated an increased risk of atrial fibrillation, especially in older individuals with TSH levels effects of SHy on all-cause and cardiovascular mortality are not clear, but recent meta-analyses suggest a modest increase in mortality, with the risk increasing with age and associated with the lowest TSH levels. The long-term consequences of SHy in young- and middle-aged adults, and in those with TSH levels are mildly low, are uncertain. For these reasons, guidelines for treatment are based on patient age, the degree of TSH suppression, symptoms consistent with hyperthyroidism, and overall cardiovascular and osteoporotic fracture risks.

The Greek state has reduced their funding on health as part of broader efforts to limit the large fiscal deficits and rising debt ratios to GDP. Benefits cuts and limitations of Social Health Insurance (SHI) reimbursements result in substantial Out of Pocket (OOP) payments in the Greek population. In this paper, we examine social health insurance's risk pooling mechanisms and the catastrophic impact that OOP payments may have on insured's income and well-being. Using data collected from a cross sectional survey in Greece, we find that the OOP payments for inpatient care in private hospitals have a positive relationship with SHI funding. Moreover, we show that the SHI funding is inadequate to total inpatient financing. We argue that the Greek health policy makers have to give serious consideration to the perspective of a SHI system which should be supplemented by the Private Health Insurance (PHI) sector.

To validate questionnaires on voice, speech, and swallowing among laryngeal cancer patients, to assess the need for and use of rehabilitation services, and to determine the association between voice, speech, and swallowing problems, and quality of life and distress. Laryngeal cancer patients at least three months post-treatment completed the VHI (voice), SHI (speech), SWAL-QOL (swallowing), EORTC QLQ-C30, QLQ-HN35, HADS, and study-specific questions on rehabilitation. Eighty-eight patients and 110 healthy controls participated. Cut off scores of 15, 6, and 14 were defined for the VHI, SHI, and SWAL-QOL (sensitivity > 90%; specificity > 80%). Based on these scores, 56% of the patients reported voice, 63% speech, and 54% swallowing problems. VHI, SHI, and SWAL-QOL scores were associated significantly with quality of life (EORTC QLQ-C30 global quality of life scale) (r = .43 (VHI and SHI) and r = .46 (SWAL-QOL)) and distress (r = .50 (VHI and SHI) and r = .58 (SWAL-QOL)). In retrospect, 32% of the patients indicated the need for rehabilitation at time of treatment, and 81% of these patients availed themselves of such services. Post-treatment, 8% of the patients expressed a need for rehabilitation, and 20% of these patients actually made use of such services. Psychometric characteristics of the VHI, SHI, and SWAL-QOL in laryngeal cancer patients are good. The prevalence of voice, speech, and swallowing problems is high, and clearly related to quality of life and distress. Although higher during than after treatment, the perceived need for and use of rehabilitation services is limited. Copyright © 2014 Elsevier Ltd. All rights reserved.

The objective of this study was to test the construct validity of the patient-reported outcomes Swallowing Quality of Life Questionnaire (SWAL-QOL) and Speech Handicap Index (SHI) in relation to objectively measured oral function among patients treated for oral or oropharyngeal cancer. The study sample consisted of patients treated for oral or oropharyngeal cancer. Outcome measures were the SWAL-QOL and the SHI, and the Functional Rehabilitation Outcomes Grade (FROG), a test to measure oral and shoulder function. Spearman's rank correlation coefficient was used to test associations between the SHI and SWAL-QOL scales, and the FROG scales. During a study period of 3 months, 38 patients (21 males, 17 females; mean age 54 years) were included who visited the outpatient clinic for follow-up care 6-155 months after surgical treatment (n = 14) or combined surgery and radiotherapy (n = 24) for oral (n = 21) or oropharyngeal cancer (n = 17). Most SWAL-QOL and SHI scales (except the SWAL-QOL Fatigue scale) correlated significantly with one or more FROG oral function scales. None of the SWAL-QOL and SHI scales correlated significantly with the FROG shoulder function scale. These results support the construct validity of the SWAL-QOL and SHI questionnaires for assessing speech and swallowing problems in daily life that are moderately but significantly related to oral function. A multidimensional assessment protocol is recommended for use in clinical practice and for research purposes for measuring oral function and swallowing- and speech-related problems in daily life among head and neck cancer patients.

The objective of this study was to investigate the usefulness of muscle ultrasound in evaluating dissociated small hand muscle atrophy, termed 'split hand', and its feasibility in the diagnosis of amyotrophic lateral sclerosis (ALS). Forty-four patients with ALS, 18 normal subjects and 9 patients with other neuromuscular disorders were included in this study. The hand muscles were divided into three regions, the median-innervated lateral hand muscle group (ML), the ulnar-innervated lateral hand muscle (UL) and the ulnar-innervated medial hand muscle (UM), and the muscle echo intensity (EI) and compound muscle action potential (CMAP) were measured. We calculated the split hand index (SHI) using muscle EI (SHI mEI ) and CMAP (SHI CMAP ) for comparison among groups. The SHI was derived by dividing muscle EI (or CMAP) measured at the ML and UL by that measured at the UM. The SHI mEI was significantly higher in patients with ALS (51.7±28.3) than in normal controls (29.7±9.9) and disease controls with other neuromuscular disorders (36.5±7.3; Pdifferentiating ALS from other neuromuscular disorders and healthy controls. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

This study examined the underlying processes and conditions that contribute to the school adjustment of shy children in Turkey, where children's interpersonal relationships in social settings and academic achievement are highly emphasized. First, we examined the unique mediating roles of children's feelings of social anxiety, depressive symptoms, and loneliness in the associations between shyness and indices of school outcomes (academic achievement and school liking/avoidance). Second, we explored the moderating role of children's peer acceptance in these associations. Fourth- and fifth-grade children (N = 599; M age  = 10.11 years, SD = 0.65; 48% girls) provided information on shyness, social anxiety, depressive symptoms, loneliness, and school liking/avoidance. Head teachers in each classroom reported on students' academic performance. The peer nomination method was used to assess children's peer relationships. Results revealed that when children displayed shy behaviours, they reported more depressive symptoms that were, in turn, associated with poorer academic performance, less school liking, and higher school avoidance. Moreover, shyness negatively predicted school liking at low levels of peer acceptance, suggesting that difficulties in peer relationships increased shy children's risk of school dissatisfaction. Overall, our findings support the importance of the interpersonal relationship context for children's adjustment within the Turkish cultural context. Statement of contribution What is already known on this subject? Shy children have difficulties initiating and maintaining social interactions, which put them at risk for a wide range of socio-emotional difficulties. Shy children have poor academic performance and experience school adjustment difficulties in North America. What does this study add? Shyness is an important risk factor for poorer academic performance and adjustment among children in Turkey. The association between shyness and

Empirical evidence on how ownership type affects the quality and cost of medical care is growing, and debate on these topics is ongoing. Despite the fact that the private sector is a major provider of hospital services in Greece, little comparative information on private versus public sector hospitals is available. The aim of the present study was to describe and compare the operation and performance of private for-profit (PFP) and public hospitals in Greece, focusing on differences in nurse staffing rates, average lengths of stay (ALoS), and Social Health Insurance (SHI) payments for hospital care per patient discharged. Five different datasets were prepared and analyzed, two of which were derived from information provided by the National Statistical Service (NSS) of Greece and the other three from data held by the three largest SHI schemes in the country. All data referred to the 3-year period from 2001 to 2003. PFP hospitals in Greece are smaller than public hospitals, with lower patient occupancy, and have lower staffing rates of all types of nurses and highly qualified nurses compared with public hospitals. Calculation of ALoS using NSS data yielded mixed results, whereas calculations of ALoS and SHI payments using SHI data gave results clearly favoring the public hospital sector in terms of cost-efficiency; in all years examined, over all specialties and all SHI schemes included in our study, unweighted ALoS and SHI payments for hospital care per discharge were higher for PFP facilities. In a mixed healthcare system, such as that in Greece, significant performance differences were observed between PFP and public hospitals. Close monitoring of healthcare provision by hospital ownership type will be essential to permit evidence-based decisions on the future of the public/private mix in terms of healthcare provision.

We adopted a descriptive and correlational research design and collected data from 261 pregnant women during their first trimester in southern Taiwan using structured questionnaires. Results showed that (1 stress was significantly and positively correlated with Yang-Xu, Yin-Xu, and Tan-Shi-Yu-Zhi constitutions, respectively; (2 Yin-Xu and Tan-Shi-Yu-Zhi constitutions had significant correlations with all symptoms of discomfort, while Yang-Xu had significant correlations with all symptoms of discomfort except for “running nose”; (3 Tan-Shi-Yu-Zhi constitution and stress were two indicators for “fatigue”; Tan-Shi-Yu-Zhi was the indicator for “nausea”; Yang-Xu and Yin-Xu were indicators for “frequent urination.” Our findings also indicate that stress level affects constitutional changes and that stress and constitutional change affect the incidence of discomfort. This research can help healthcare professionals observe these discomforts and provide individualized care for pregnant women, to nurture pregnant women into neutral-type constitution, minimize their levels of discomfort, and promote the health of the fetus and the mother.

To investigate the direct and indirect associations of sleep hygiene with daytime sleepiness, depressive symptoms, and quality of life (QoL), in newly diagnosed, untreated patients with mild obstructive sleep apnea (OSA). Data were collected from adults with mild OSA. The Sleep Hygiene Index (SHI), Sleep Problems Index-1 (SPI-1) of the Medical Outcomes Study-Sleep Scale, Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Medical Outcomes Study Short-Form Health survey (SF-36) were used to evaluate patients. To determine the indirect and direct associations between SHI and disease outcomes, the Sobel test and multiple linear regression analyses were used, respectively. When we evaluated the direct associations, we excluded 3 items of the original SHI which were more reflective of general health rather than sleep-specific habits and environments. In total, 260 patients with mild OSA participated in this study. The average age, AHI, and SHI scores were 49.1 years (SD 12.5), 9.3/h (SD 2.9), and 24.7 (SD 6.0), respectively. Here, ≥ 10% of participants indicated poor sleep hygiene behaviors on 7 of 13 items. Young age and men were associated with higher SHI scores (both phygiene is indirectly related to daytime sleepiness, depressive symptoms, QoL via sleep quality and also related to daytime sleepiness and QoL independent of sleep quality in mild OSA patients.

2011-11-01

Tissue second-harmonic imaging is currently the default mode in commercial diagnostic ultrasound systems. A new modality, superharmonic imaging (SHI), combines the third through fifth harmonics originating from nonlinear wave propagation through tissue. SHI could further improve the resolution and quality of echographic images. The superharmonics have gaps between the harmonics because the transducer has a limited bandwidth of about 70% to 80%. This causes ghost reflection artifacts in the superharmonic echo image. In this work, a new dual-pulse frequency compounding (DPFC) method to eliminate these artifacts is introduced. In the DPFC SHI method, each trace is constructed by summing two firings with slightly different center frequencies. The feasibility of the method was established using a single-element transducer. Its acoustic field was modeled in KZK simulations and compared with the corresponding measurements obtained with a hydrophone apparatus. Subsequently, the method was implemented on and optimized for a setup consisting of an interleaved phased-array transducer (44 elements at 1 MHz and 44 elements at 3.7 MHz, optimized for echocardiography) and a programmable ultrasound system. DPFC SHI effectively suppresses the ghost reflection artifacts associated with imaging using multiple harmonics. Moreover, compared with the single-pulse third harmonic, DPFC SHI improved the axial resolution by 3.1 and 1.6 times at the -6-dB and -20-dB levels, respectively. Hence, DPFC offers the possibility of generating harmonic images of a higher quality at a cost of a moderate frame rate reduction.

Radiation has been used as a processing technique to modify structural, chemical, physical and morphological properties of polymers and its nanocomposite and can thus be used as a method to control the rate of degradation. The swift heavy ions (SHI) irradiation effects on the structural properties of poly(lactide-co-glycolide) nanocomposites containing 5 wt% organo-montmorillonite (OMMT) clay by irradiating with 50 MeV Li{sup 3+} and 180 MeV Ag{sup 8+} ions has been studied at different fluences. The structural responses of PLGA nanocomposite under the influence of SHI were studied using Fourier transform infrared (FTIR) spectroscopy. The presence of clay and irradiation by swift heavy ions (SHI) brings out interesting changes in structural properties of nanocomposite.

Control of ciliary motility by Ca2+: Integration of Ca2+-dependent functions and targets for Ca2+ action

International Nuclear Information System (INIS)

Evans, T.C.

1988-01-01

To identify functions that regulate Ca 2+ -induced ciliary reversal in Paramecium, mutants defective in terminating depolarization-induced backward swimming were selected. Six independent recessive mutations (k-shy) comprising two complementation groups, k-shyA and k-shyB, were identified. All mutants exhibited prolonged backward swimming in depolarizing solutions. Voltage clamp studies revealed that mutant Ca 2+ current amplitudes were reduced, but could be restored to wild type levels by EGTA injection. The recovery of the mutant Ca 2+ current from Ca 2+ -dependent inactivation, and the decay of the Ca 2+ -dependent K + and Ca 2+ -dependent Na + currents after depolarization were slow in k-shy compared to wild type. To identify protein targets of Ca 2+ action, ciliary proteins that interact with calmodulin (CaM) were characterized. With a 125 I-CaM blot assay, several CaM-binding proteins were identified including axonemal, soluble, and membrane-bound polypeptides. Competitive displacement studies with unlabeled Paramecium CaM, bovine CaM, and troponinC suggested that both protein types bind CaM with high affinity and specificity. To examine the presence of CaM-binding sites in intact axonemes, a filtration binding assay was developed

Searching of superheavy elements, the charge spectra of heavy nuclei in Galactic Cosmic Rays was investigated within the OLYMPIA experiment using the database of etched ion tracks in meteorite olivine. Etching results in the formation of hollow syringe-like channels with diameters of 1–10 μm along the trajectories of these swift heavy ions (SHI). According to the activated complex theory, the local chemical activity is determined by an increase of the specific Gibbs energy of the lattice stimulated by structure transformations, long-range elastic fields, and interatomic bonds breaking generated in the vicinity of the ion trajectory. To determine the dependencies of the Gibbs free energy increase in SHI tracks in olivine on the mass, energy and charge of a projectile, we apply a multiscale model of excitation and relaxation of materials in the vicinity of the SHI trajectory (SHI tracks). Effect of spreading of fast electrons from the ion trajectory causing neutralization of metallic atoms resulting in an increase of the chemical activity of olivine at long distances from the ion trajectory (up to 5 μm) is estimated and discussed.

2013-01-01

This letter presents an assessment of winter cloudiness variability over Northern Eurasia regions related to the Siberian High intensity (SHI) variations during 1966–2010. An analysis of cloud fraction and the occurrence of different cloud types was carried out based on visual observations from almost 500 Russian meteorological stations. The moonlight criterion was implemented to reduce the uncertainty of night observations. The SHI was defined based on sea-level pressure fields from different reanalyses. We found a statistically significant negative correlation of cloud cover with the SHI over central and southern Siberia and the southern Urals with regression coefficients around 3% hPa −1 for total cloud fraction (TCF) for particular stations near the Siberian High center. Cross-wavelet analysis of TCF and SHI revealed a long-term relationship between cloudiness and the Siberian High. Generally, the Siberian High intensification by 1 hPa leads to a replacement of one overcast day with one day without clouds, which is associated mainly with a decrease in precipitating and stratiform clouds. These changes point to a positive feedback between cloudiness and the Siberian High. (letter)

Redistribution through social health insurance: evidence on citizen preferences.

Science.gov (United States)

Pfarr, Christian; Schmid, Andreas

2016-06-01

The extent of social health insurance (SHI) and supplementary private insurance is frequently analyzed in public choice. Most of these analyses build on the model developed by Gouveia (1997), who defines the extent of SHI as consequence of a choice by self-interested voters. In this model, an indicator reflecting individuals' relative income position and relative risk of falling ill determines the voting decision. Up to now, no empirical evidence for this key assumption has been available. We test the effect of this indicator on individuals' preferences for the extent of SHI in a setting with mandatory SHI that can be supplemented by private insurance. The data is based on a DCE conducted in the field with a representative sample of 1538 German citizens in 2012. Conditional logit and latent class models are used to analyze preference heterogeneity. Our findings strongly support the assumptions of the models. Individuals likely to benefit from public coverage show a positive marginal willingness to pay (MWTP) for both a shift away from other beneficiary groups toward the sick and an expansion of publicly financed resources, and the expected net payers have a negative MWTP and prefer lower levels of public coverage.

Social health insurance in Nepal: A health system departure toward the universal health coverage.

Pokharel, Rajani; Silwal, Pushkar Raj

2018-04-10

The World Health Organization has identified universal health coverage (UHC) as a key approach in reducing equity gaps in a country, and the social health insurance (SHI) has been recommended as an important strategy toward it. This article aims to analyze the design, expected benefits and challenges of realizing the goals of UHC through the recently launched SHI in Nepal. On top of the earlier free health-care policy and several other vertical schemes, the SHI scheme was implemented in 2016 and has reached population coverage of 5% in the implemented districts in just within a year of implementation. However, to achieve UHC in Nepal, in addition to operationalizing the scheme, several other requirements must be dealt simultaneously such as efficient health-care delivery system, adequate human resources for health, a strong information system, improved transparency and accountability, and a balanced mix of the preventive, health promotion, curative, and rehabilitative services including actions to address the social determinants of health. The article notes that strong political commitment and persistent efforts are the key lessons learnt from countries achieving progressive UHC through SHI. Copyright © 2018 John Wiley & Sons, Ltd.

Scanner calibration revisited

2010-07-01

Full Text Available Abstract Background Calibration of a microarray scanner is critical for accurate interpretation of microarray results. Shi et al. (BMC Bioinformatics, 2005, 6, Art. No. S11 Suppl. 2. reported usage of a Full Moon BioSystems slide for calibration. Inspired by the Shi et al. work, we have calibrated microarray scanners in our previous research. We were puzzled however, that most of the signal intensities from a biological sample fell below the sensitivity threshold level determined by the calibration slide. This conundrum led us to re-investigate the quality of calibration provided by the Full Moon BioSystems slide as well as the accuracy of the analysis performed by Shi et al. Methods Signal intensities were recorded on three different microarray scanners at various photomultiplier gain levels using the same calibration slide from Full Moon BioSystems. Data analysis was conducted on raw signal intensities without normalization or transformation of any kind. Weighted least-squares method was used to fit the data. Results We found that initial analysis performed by Shi et al. did not take into account autofluorescence of the Full Moon BioSystems slide, which led to a grossly distorted microarray scanner response. Our analysis revealed that a power-law function, which is explicitly accounting for the slide autofluorescence, perfectly described a relationship between signal intensities and fluorophore quantities. Conclusions Microarray scanners respond in a much less distorted fashion than was reported by Shi et al. Full Moon BioSystems calibration slides are inadequate for performing calibration. We recommend against using these slides.

Role of the irradiation temperature on the modifications of swift-heavy-ion irradiated polyethylene

International Nuclear Information System (INIS)

Melot, M.; Ngono-Ravache, Y.; Balanzat, E.

2003-01-01

The damage processes triggered by swift heavy ions, SHI, can be very different to those induced by classical low ionising particles. This is due to the very high electronic stopping power, (dE/dx) e , of SHI. This paper concerns the effects of SHI on polyethylene, PE. In PE, low (dE/dx) e irradiations induce crosslinking and in-chain double bond formation. At high (dE/dx) e , the creation yield of vinyl groups becomes significant. Above a (dE/dx) e threshold, alkyne and allene groups appear. We present results on low temperature irradiations that bring new enlightenment on the damage process by preventing the migration of radiation-induced radicals and molecules. Two SHI specific modifications are studied: vinyl groups and alkyne end groups. We have irradiated PE films with oxygen and sulphur beams at 13.6 and 11.2 MeV/amu, respectively. The modifications were followed by in situ infrared spectroscopy (FTIR). We have performed irradiations at 8 and 290 K. The samples irradiated at 8 K have been annealed up to 290 K for investigating the effect of radical migration. Lowering the irradiation temperature to 8 K increases the creation yield of vinyl groups and alkyne end groups. The enhancement factor between 290 and 8 K is around three. Consequently the formation of defects specific to SHI irradiations is sensitive to radical migration and hence requires some time. During annealing, the alkyne concentration remains stable indicating that the creation of this group cannot be induced by radical recombination. The annealing spectra of vinyl groups are more complex

All participants answered the German SHI, the short form of the Barratt Impulsiveness Scale (BIS-15, the ultra-brief Patient Health Questionnaire for Depression and Anxiety (PHQ-4, and provided sociodemographic information. The one-factorial structure of the SHI was replicated using a confirmatory factor analysis. Internal consistency coefficients were sufficient and in line with previous studies. Almost half of the sample (49% acknowledged at least one self-harming behavior over the life-span, most frequently indirect forms of self-harm. The rate of participants who engaged in at least one SHI behavior was higher among men than women (51.6% vs. 46.9%, respectively, χ2 = 5.38, p = 0.020. Higher SHI scores were related to younger age, male gender, living alone, more symptoms of anxiety and depression (PHQ-4, higher impulsivity scores (BIS-15, and suffering from obesity grade 2. Women engaged more often in discreet forms of self-harm than men, e.g., preventing wounds from healing, exercising an injury, starving, and abusing laxatives. In terms of other indirect self-harming behaviors, men admitted more often driving recklessly, being promiscuous and losing a job on purpose, while women reported more frequently engaging in emotionally abusive relationships. With respect to direct self-harm, women were more likely to endorse suicide attempts and cutting, while men admitted more often head-banging. The findings suggest that self-harm constitutes a common problem. Future longitudinal studies are required to examine the natural course, sociodemographic and psychopathological risk factors, as well as possible time-trends of self

Swift Heavy Ion (SHI) irradiation with 200 MeV Ag 9+ -ion beam at ion fluences of 1E11, 5E11, 1E12, and 5E12 for tuning of electrical transport properties of VO 2 thin films fabricated by so–gel technique on alumina substrates has been demonstrated in the present paper. The point defects created by SHI irradiation modulate metal to insulator phase transition temperature, carrier concentration, carrier mobility, electrical conductivity, and Seebeck coefficient of VO 2 thin films. The structural properties of the films were characterized by XRD and Raman spectroscopy and crystallite size was found to decrease upon irradiation. The atomic force microscopy revealed that the surface roughness of specimens first decreased and then increased with increasing fluence. Both resistance as well as Seebeck coefficient measurements demonstrated that all the samples exhibit metal–insulator phase transition and the transition temperatures decreases with increasing fluence. Hall effect measurements exhibited that carrier concentration increased continuously with increasing fluence which resulted in an increase of electrical conductivity by several orders of magnitude in the insulating phase. Seebeck coefficient in insulating phase remained almost constant in spite of an increase in the electrical conductivity by several orders of magnitude making SHI irradiation an alternative stratagem for augmentation of thermoelectric performance of the materials. The carrier mobility at room temperature decreased up to the beam fluence of 5E11 and then started increasing whereas Seebeck coefficient in metallic state first increased with increasing ion beam fluence up to 5E11 and thereafter decreased. Variation of these electrical transport parameters has been explained in detail. - Highlights: • Thermoelectric properties of VO 2 thin films enhance upon SHI irradiation. • Structural properties show that crystallite size decrease upon SHI irradiation. • Metal–insulator phase

Severe hearing impairment among military veterans--United States, 2010.

Science.gov (United States)

2011-07-22

A substantial proportion of hearing loss in the United States is attributable to employment-related exposure to noise. Among military veterans, the most common service-connected disabilities are hearing impairments, suggesting that occupational noise exposure during military service might cause more veterans to have hearing loss than nonveterans. However, a recent analysis of data from the 1993-1995 Epidemiology of Hearing Loss Study did not find significant differences between the two groups. To further investigate hearing loss among veterans, specifically the prevalence of severe hearing impairment (SHI), data from the 2010 Annual Social and Economic Supplement (ASEC) to the Current Population Survey (CPS) were analyzed. This report describes the results of those analyses, which indicated that the prevalence of SHI among veterans was significantly greater than among nonveterans. Veterans were 30% more likely to have SHI than nonveterans after adjusting for age and current occupation, and veterans who served in the United States or overseas during September 2001-March 2010, the era of overseas contingency operations (including Operations Enduring Freedom and Iraqi Freedom), were four times more likely than nonveterans to have SHI. These findings suggest a need for increased emphasis on improving military hearing conservation programs (HCPs) and on hearing loss surveillance in military and veterans' health systems.

School health instruction (SHI) is the instructional aspects of school health programme. It provides information on key health issues to school children who are in their formative years. A cross sectional descriptive study of all the primary schools in a focal Local Government Area in Nigeria was carried out to ascertain the implementation of SHI with regards to the contents, methods of delivery and teachers preparation for health teaching using an evaluation checklist for SHI. There were more female pupils enrolled in the study area compared to their male counterparts with a male to female ratio of 0.9:1.0 and only 3.0% of the teachers had In-service training on health related issues in the previous five years preceding the study. 79.4% of the teachers had the recommended qualification to work in the schools. Teachings on emotional health, communicable diseases and safety education were sparingly given by 1.6%, 4.7% and 56% schools respectively. Only three (4.7%) schools (all private) had health instruction given by designated health education staff. No school gave health instruction at least thrice a week as recommended. Compliance with the implementation of SHI was very poor in the study area.

Towards Universal Health Coverage via Social Health Insurance in China: Systemic Fragmentation, Reform Imperatives, and Policy Alternatives.

He, Alex Jingwei; Wu, Shaolong

2017-12-01

China's remarkable progress in building a comprehensive social health insurance (SHI) system was swift and impressive. Yet the country's decentralized and incremental approach towards universal coverage has created a fragmented SHI system under which a series of structural deficiencies have emerged with negative impacts. First, contingent on local conditions and financing capacity, benefit packages vary considerably across schemes, leading to systematic inequity. Second, the existence of multiple schemes, complicated by massive migration, has resulted in weak portability of SHI, creating further barriers to access. Third, many individuals are enrolled on multiple schemes, which causes inefficient use of government subsidies. Moral hazard and adverse selection are not effectively managed. The Chinese government announced its blueprint for integrating the urban and rural resident schemes in early 2016, paving the way for the ultimate consolidation of all SHI schemes and equal benefits for all. This article proposes three policy alternatives to inform the consolidation: (1) a single-pool system at the prefectural level with significant government subsidies, (2) a dual-pool system at the prefectural level with risk-equalization mechanisms, and (3) a household approach without merging existing pools. Vertical integration to the provincial level is unlikely to happen in the near future. Two caveats are raised to inform this transition towards universal health coverage.

The high level of out of pocket (OOP) payments constitutes a major concern for Greece and several other European and OECD countries as a result of the significant down turning of their public health finances due to the 2008 financial crisis. The basic objective of this study is to provide empirical evidence on the effect of combining social health insurance (SHI) and private health insurance (PHI) on OOP payments. Further, this study examines the catastrophic impact of OOP payments on insured's welfare using the incidence and intensity methodological approach of measuring catastrophic health care expenditures. Conducting a cross-sectional survey in Greece in 2013, we find that the combination of SHI-PHI has a strong negative influence on insured OOP payments for inpatient health care in private hospitals. Furthermore, our results indicate that SHI coverage is not sufficient by itself to manage with this issue. Moreover, we find that poor people present a greater tendency to incur catastrophic OOP expenditures for hospital health care in private providers. Drawing evidence from Greece, a country with huge fiscal problems that has suffered the consequences of the economic crisis more than any other, could be a starting point for policymakers to consider the perspective of SHI-PHI co-operation against OOP payments more seriously.

GaP single crystals were irradiated with slow highly charged ions (HCI) using 114 keV {sup 129}Xe{sup (33–40)+} and with various swift heavy ions (SHI) of 30 MeV I{sup 9+} and 374 MeV–2.2 GeV {sup 197}Au{sup 25+}. The irradiated surfaces were investigated by scanning force microscopy (SFM). The irradiations with SHI lead to nanohillocks protruding from the GaP surfaces, whereas no changes of the surface topography were observed after the irradiation with HCI. This result indicates that a potential energy above 38.5 keV is required for surface nanostructuring of GaP. In addition, strong coloration of the GaP crystals was observed after irradiation with SHI. The effect was stronger for higher energies. This was confirmed by measuring an increased extinction coefficient in the visible light region.

Swift heavy ion irradiation effects in {alpha} poly(vinylidene fluoride); Etude des effets induits par les ions lourds energetiques dans le poly(fluorure de vinylidene)

Energy Technology Data Exchange (ETDEWEB)

Le Bouedec, A

1999-11-29

The goal of this study is to characteristic and to localised defects created in {alpha} Poly (vinylidene fluoride) after swift heavy ion irradiations. PVDF films are irradiated with several Swift Heavy Ions (SHI), in the electronic stopping power (dE/dx){sub e}, in order to study the influence of irradiation parameters (absorbed dose, ion). These irradiated films are studied by different analysis techniques such as FTIR, ESR (X and Q band) spectroscopies and DSC. The crystalline level of PVDF is about 50% and we follow it destruction and amorphization as the absorbed dose increase by DSC and FTIR studies. The variation of the various FTIR bands allow us to observe the unsaturations induced by SHI radiations. Two sets of defects are observed: those which yield is sensitive to an increase of (dE/dx){sub e} and those that are not. A spatial distribution of the various defects within the talent track is provided and defects that are difficult to create are the closest of the ion path. The different kind of radicals created after irradiations are studied by ESR spectroscopy. Alkyl, peroxy and polyenyl radicals are detected after SHI radiations like after electron or {gamma} irradiations. Their yield of creation is independent of (dE/dx){sub e} and their localised in the crystalline zone or/and at the interfacial zone between crystalline and amorphous one. An other kind of radicals is created only after SHI radiations that are specific of the SHI-polymer interaction. We observe that these radicals are localised on a carbon cluster, in the core of the latent track for low doses and highly sensitive at the (dE/dx){sub e} of the ion. (author)

Surface damage appears on materials irradiated by highly charged ions (HCI). Since a direct link has been found between surface damage created by HCI with the one created by swift heavy ions (SHI), the inelastic thermal spike model (i-TS model) developed to explain track creation resulting from the electron excitation induced by SHI can also be applied to describe the response of materials under HCI which transfers its potential energy to electrons of the target. An experimental description of the appearance of the hillock-like nanoscale protrusions induced by SHI at the surface of CaF 2 is presented in comparison with track formation in bulk which shows that the only parameter on which we can be confident is the electronic energy loss threshold. Track size and electronic energy loss threshold resulting from SHI irradiation of CaF 2 is described by the i-TS model in a 2D geometry. Based on this description the i-TS model is extended to three dimensions to describe the potential threshold of appearance of protrusions by HCI in CaF 2 and to other crystalline materials (LiF, crystalline SiO 2 , mica, LiNbO 3 , SrTiO 3 , ZnO, TiO 2 , HOPG). The strength of the electron-phonon coupling and the depth in which the potential energy is deposited near the surface combined with the energy necessary to melt the material defines the classification of the material sensitivity. As done for SHI, the band gap of the material may play an important role in the determination of the depth in which the potential energy is deposited. Moreover larger is the initial potential energy and larger is the depth in which it is deposited.

1996-01-01

Photoperiod and harvest scenario of cowpea (Vigna unguiculata L. Walp) canopies were manipulated to optimize productivity for use in future controlled ecological life-support systems. Productivity was measured by edible yield rate (EYR:g m-2 day-1), shoot harvest index (SHI: g edible biomass [g total shoot dry weight]), and yield-efficiency rate (YER:g edible biomass m-2 day-1 per[g nonedible shoot dry weight]). Breeding lines 'IT84S-2246' (S-2246) and "IT82D-889' (D-889) were grown in a greenhouse under 8-, 12-, or 24-h photoperiods. S-2246 was short-day and D-889 was day-neutral for flowering. Under each photoperiod, cowpeas were harvested either for leaves only, seeds only, or leaves plus seeds (mixed harvest). Photoperiod did not affect EYR of either breeding line for any harvest scenario tested. Averaged over both breeding lines, seed harvest gave the highest EYR at 6.7 g m-2 day-1. The highest SHI (65%) and YER (94 mg m-2 day-1 g-1) were achieved for leaf-only harvest of D-889 under an 8-h photoperiod. For leaf-only harvest of S-2246, both SHI and YER increased with increasing photoperiod, but declined for seed-only and mixed harvests. However, photoperiod had no effect on SHI or YER for D-889 for any harvest scenario. A second experiment utilized the short-day cowpea breeding line 'IT89KD-288' (D-288) and the day-neutral breeding line 'IT87D-941-1' (D-941) to compare yield parameters using photoperiod extension under differing lamp types. This experiment confirmed the photoperiod responses of D-889 and S-2246 to a mixed-harvest scenario and indicated that daylength extension with higher irradiance from high pressure sodium lamps further suppressed EYR, SHI, and YER of the short-day breeding line D-288.

Discrimination of Dendrobium officinale and Its Common Adulterants by Combination of Normal Light and Fluorescence Microscopy

2014-03-01

Full Text Available The stems of Dendrobium officinale Kimura et Migo, named Tie-pi-shi-hu, is one of the most endangered and precious species in China. Because of its various pharmacodynamic effects, D. officinale is widely recognized as a high-quality health food in China and other countries in south and south-east Asia. With the rising interest of D. officinale, its products have a high price due to a limited supply. This high price has led to the proliferation of adulterants in the market. To ensure the safe use of D. officinale, a fast and convenient method combining normal and fluorescence microscopy was applied in the present study to distinguish D. officinale from three commonly used adulterants including Zi-pi-shi-hu (D. devonianum, Shui-cao-shi-hu (D. aphyllum, Guang-jie-shi-hu (D. gratiosissimum. The result demonstrated that D. officinale could be identified by the characteristic “two hat-shaped” vascular bundle sheath observed under the fluorescence microscopy and the distribution of raphides under normal light microscopy. The other three adulterants could be discriminated by the vascular bundle differences and the distribution of raphides under normal light microscopy. This work indicated that combination of normal light and fluorescence microscopy is a fast and efficient technique to scientifically distinguish D. officinale from the commonly confused species.

Should providers be allowed to extra bill for uncovered services? Debate, resolution, and sequel in Japan.

Science.gov (United States)

Ikegami, Naoki

2006-12-01

Japan has managed to provide universal coverage at relatively low cost by containing prices and restricting the conditions for which services can be billed in the compulsory social health insurance (SHI) program. However, decline in Japan's economic growth ushered in new actors backed by the prime minister who proposed that the providers should be allowed to extra bill for services not covered by the SHI. In 2004 they took the strategy of drawing the attention of the public to areas where the rigidity of the current prohibition appeared to be unfair and ridiculous. They were opposed by the Ministry of Health, Labor, and Welfare and the Japan Medical Association, who strongly objected on the grounds of safety and equity. The compromise reached by the two ministers in charge led to a clarification of the services that are to be covered and of the process for extending coverage to new procedures and drugs. The prohibition on extra billing has remained essentially unchanged, but the momentum for deregulation has been lost. In 2005 an alternate proposal was made to contain SHI expenditures by introducing a global cap on health expenditures and increasing out-of-pocket payment. Although this proposal was not fully adopted, the gradual decline in SHI benefit levels could lead to a renewed move to allow extra billing.

Recent study has shown that RNA interference (RNAi) is efficient in emerald ash borer (EAB), Agrilus planipennis, and that ingestion of double-stranded RNA (dsRNA) targeting specific genes causes gene silencing and mortality in neonates. Here, we report on the identification of highly effective target genes for RNAi-mediated control of EAB. We screened 13 candidate genes in neonate larvae and selected the most effective target genes for further investigation, including their effect on EAB adults and on a non-target organism, Tribolium castaneum. The two most efficient target genes selected, hsp (heat shock 70-kDa protein cognate 3) and shi (shibire), caused up to 90% mortality of larvae and adults. In EAB eggs, larvae, and adults, the hsp is expressed at higher levels when compared to that of shi. Ingestion of dsHSP and dsSHI caused mortality in both neonate larvae and adults. Administration of a mixture of both dsRNAs worked better than either dsRNA by itself. In contrast, injection of EAB.dsHSP and EAB.dsSHI did not cause mortality in T. castaneum. Thus, the two genes identified cause high mortality in the EAB with no apparent phenotype effects in a non-target organism, the red flour beetle, and could be used in RNAi-mediated control of this invasive pest.

Sleeping money: investigating the huge surpluses of social health insurance in China.

Science.gov (United States)

Liu, JunQiang; Chen, Tao

2013-12-01

The spreading of social health insurance (SHI) worldwide poses challenges for fledging public administrators. Inefficiency, misuse and even corruption threaten the stewardship of those newly established health funds. This article examines a tricky situation faced by China's largest SHI program: the basic health insurance (BHI) scheme for urban employees. BHI accumulated a 406 billion yuan surplus by 2009, although the reimbursement level was still low. Using a provincial level panel database, we find that the huge BHI surpluses are related to the (temporarily) decreasing dependency ratio, the steady growth of average wages, the extension of BHI coverage, and progress in social insurance agency building. The financial situations of local governments and risk pooling level also matter. Besides, medical savings accounts result in about one third of BHI surpluses. Although these findings are not causal, lessons drawn from this study can help to improve the governance and performance of SHI programs in developing countries.

Structural modification by swift heavy ion at metal/Si interface

2003-06-01

Transition metal silicides produced by swift heavy ion (SHI) irradiation have found applications in ultra-large-scale integrated circuits due to their small contact resistivities and higher thermal and chemical stabilities. In the present work, the mixing in Ni/Si and Ti/Si systems was studied under irradiation with Au ions. A layer of Ni (15 nm) and Ti (18 nm) was deposited by e-gun evaporation on Si (1 0 0) substrate at 10{sup -8} Torr vacuum. The samples were irradiated with 95 Mev Au ions at room temperature to a fluence of 10{sup 13} ions/cm{sup 2} and 1 pna beam current. Rutherford backscattering spectroscopy and X-Ray reflectivity have been employed to characterize the samples. The large electronic excitation due to SHI irradiation produces defects in the system. It is expected that SHI irradiation followed by thermal annealing in Ni/Si system will provide the required energy to the atoms to diffuse across the interface resulting in mixing.

Swift heavy ion (SHI) irradiation is a special technique for inducing physical and chemical modifications in bulk materials. In the present work, the SHI hs been used to prepare nanocomposites with homogeneously dispersed nanoparticles. The nanographite was synthesized from graphite using the intercalation-exfoliation method. PMMA Poly(methyl methacrylate)/graphite nanocomposites have been synthesized by in situ polymerization. The prepared PMMA/graphite nanocomposite films were irradiated with SHI irradiation (Ni ion beam, 80 MeV and C ion beam, 50 MeV) at a fluence of 1×1010 to 3×1012 ions/cm2. The nanocomposite films were characterized by scanning electron microscope (SEM) and were evaluated for their electrical and sensor properties. After irradiation, significant changes in surface morphology of nanocomposites were observed as evident from the SEM images, which show the presence of well-distributed nanographite platelets. The irradiated nanocomposites exhibit better electrical and sensor properties for the detection of nitroaromatics with marked improvement in sensitivity as compared with unirradiated nanocomposites.

Full Text Available This book contains three novellas originally written in Chinese by the Qinghai author Jing Shi. The novellas provide a finely textured portrayal of Qinghai rural life in the twentieth century. An introduction and transcribed interview provide context to the stories and their author. From the introduction by Keith Dede: "The wide appeal of Jing Shi's fiction is certainly something he welcomes. As he sees it, literature, at one level, should be entertaining. Stories are a way for people to derive pleasure, enjoy a laugh, and while away some time. But stories are also about communication, about communicating ideas concerning the ironies of life and the trajectory of the human condition. Jing Shi thinks deeply about the people of rural Qinghai, their culture, their predicaments, their hopes, and their tragedies, and his stories communicate his thoughts about these things, but also his deep affection for the people and culture that raised him."

The SHiP facility at CERN

Searches for new physics with accelerators are being performed at the LHC, looking for high massive particles coupled to matter with ordinary strength. A new experimental facility meant to search for very weakly coupled particles in the few GeV mass domain has been recently proposed. The existence of such particles, foreseen in dierent theoretical models beyond the Standard Model, is largely unexplored from the experimental point of view. A beam dump facility, built at CERN in the north area, using 400 GeV protons is a copious factory of charmed hadrons and could be used to probe the existence of such particles. The beam dump is also an ideal source of tau neutrinos, the less known particle in the Standard Model. In particular, tau anti-neutrinos have not been directly observed so far. We report the physics potential of such an experiment and outline the performances of a detector operating at the same facility for the search for the tau --> mu mu mu decay

Creation of nanoscale objects by swift heavy ion track manipulations

International Nuclear Information System (INIS)

Fink, D.; Petrov, A.; Stolterfoht, N.

2003-01-01

In this work we give an overview of the possibilities to create new objects with nanoscale dimensions with ion tracks, for future applications. This can be realized in two ways: by manipulation of latent swift heavy ion (SHI) tracks, or by embedding specific structures within etched SHI tracks. In the first case one can make use of irradiation effects such as phase transitions and chemical or structural changes along the tracks. In the latter case, one can fill etched SHI tracks with metals, semiconductors, insulating and conducting polymers, fullerite, or colloides. Wires and tubules with outer diameters, between about 50 nm and 5 μm and lengths of up to about 100 μm can be obtained. The most important production techniques are galvanic and chemical depositions. Ion Transmission Spectrometry has turned out to be an especially useful tool for the characterisation of the produced objects. Present studies aim at the construction of condensers, magnets, diodes, and sensors in etched tracks. An obstacle for the practical realization of smallest-size polymeric ion track devices is the statistical distribution of the ion tracks on the target areas, which yields some pixels without any track, and other pixels even with overlapping tracks on a given sample. In a first test experiment we demonstrate that one can, in principle, overcome that problem by taking self-ordered porous foils as masks for subsequent high-fluence SHI irradiation. (author)

To explore the influence of secular trends in body height and weight on the prevalence of overweight and obesity among Chinese children and adolescents. The data were obtained from five cross-sectional Chinese National Surveys on Students' Constitution and Health. Overweight/obesity was defined as BMI-for-age Z-score of per the Wold Health Organization (WHO) reference values. Body height and weight for each sex and age were standardized to those reported in 1985 (standardized height: SHY; standardized weight: SWY) and for each sex and year at age 7 (standardized height: SHA; standardized weight: SWA) using the Z-score method. The prevalence of overweight/obesity in Chinese children was 20.2% among boys and 10.7% among girls in 2010 and increased continuously from 1985 to 2010. Among boys and girls of normal weight, SHY and SHA were significantly greater than SWY and SWA, respectively (P overweight/obesity, SHY was significantly lower than SWY (P overweight boys aged 7-8 years and girls aged 7-9 years. SHY/SHW and SHA/SWA among normal-weight groups were greater than among overweight and obese groups (P overweight/obesity among Chinese children may be related to a rapid increase in body weight before age 9 and lack of secular increase in body height after age 12.

In medical ultrasound, fundamental imaging (FI) uses the reflected echoes from the same spectral band as that of the emitted pulse. The transmission frequency determines the trade-off between penetration depth and spatial resolution. Tissue harmonic imaging (THI) employs the second harmonic of the emitted frequency band to construct images. Recently, superharmonic imaging (SHI) has been introduced, which uses the third to the fifth (super) harmonics. The harmonic level is determined by two competing phenomena: nonlinear propagation and frequency dependent attenuation. Thus, the transmission frequency yielding the optimal trade-off between the spatial resolution and the penetration depth differs for THI and SHI. This paper quantitatively compares the concepts of fundamental, second harmonic, and superharmonic echocardiography at their optimal transmission frequencies. Forward propagation is modeled using a 3D-KZK implementation and the iterative nonlinear contrast source (INCS) method. Backpropagation is assumed to be linear. Results show that the fundamental lateral beamwidth is the narrowest at focus, while the superharmonic one is narrower outside the focus. The lateral superharmonic roll-off exceeds the fundamental and second harmonic roll-off. Also, the axial resolution of SHI exceeds that of FI and THI. The far-field pulse-echo superharmonic pressure is lower than that of the fundamental and second harmonic. SHI appears suited for echocardiography and is expected to improve its image quality at the cost of a slight reduction in depth-of-field.

[Market Concentration in the Statutory Health Insurance of Germany since the Introduction of Free Choice of Sickness Funds].

Götze, R

2016-11-01

Background: The expansion of trust law to the German statutory health insurance (SHI) and the declining numbers of sickness funds suggest a strong concentration process in the German SHI market. The paper examines the level and development of market concentration since the introduction of the free choice of sickness funds in 1996. Data: The study is based on a dataset containing information on membership, contribution rate, openness, area of activity and legal successor for all sickness funds in the period from 1996 to 2013. Methods: Market concentration is measured by the concentration rate (cumulative market share of the largest market participants) and the Herfindahl-Hirschman index (HHI). In addition, the change in the HHI is also disaggregated into 3 factors: opening, switching and fusion of sickness funds. Results: Concentration rate and HHI decreased significantly between 1996 and 2008 due to opening of former closed sickness funds and a switching behaviour from large to small funds. The SHI Competition Enhancement Act of 2007 led to a turnaround. The reform permitted cross-type mergers and introduced a completely new system of budget allocation with the central health fund. The latter put an end to the growing membership of small funds due to adverse selection processes. As a result, market concentration in the German SHI rises. Although recent mega-mergers were uncritical for nationwide competition, the study already indicates the risk of market dominance on the regional level. © Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available Wireless sensor networks (WSNs consist of sensors, gateways and users. Sensors are widely distributed to monitor various conditions, such as temperature, sound, speed and pressure but they have limited computational ability and energy. To reduce the resource use of sensors and enhance the security of WSNs, various user authentication protocols have been proposed. In 2011, Yeh et al. first proposed a user authentication protocol based on elliptic curve cryptography (ECC for WSNs. However, it turned out that Yeh et al.’s protocol does not provide mutual authentication, perfect forward secrecy, and key agreement between the user and sensor. Later in 2013, Shi et al. proposed a new user authentication protocol that improves both security and efficiency of Yeh et al.’s protocol. However, Shi et al.’s improvement introduces other security weaknesses. In this paper, we show that Shi et al.’s improved protocol is vulnerable to session key attack, stolen smart card attack, and sensor energy exhausting attack. In addition, we propose a new, security-enhanced user authentication protocol using ECC for WSNs.

The Centers for Disease Control and Prevention's School Health Index (SHI), a guide for completing a coordinated school-based program needs assessment relative to healthy eating, physical activity, a tobacco-free lifestyle, and prevention of other health risk behaviors and conditions, was used to assess current programming at 3 midwestern middle schools. Employing somewhat different procedures, data were collected from focus groups comprising school administrators, teachers, parents, community members, and students. Participants responded to SHI module questions and provided comments based on their perceptions. Both quantitative and qualitative data were recorded for each module, after which participants answered 3 planning questions intended to guide prioritization of actions to improve policies and programs based on importance, cost, time, commitment, and feasibility. Each school developed recommendations and strategies based on highest priority needs related to community involvement, professional development, health screenings, and health education materials in classrooms. The experience of completing the SHI in 3 different schools provided important insights about the data collection process as well as assessment results that have implications for the design and implementation of prevention programs.

BACKGROUND Insufficient attention has been paid to the process of conducting the Centers for Disease Control and Prevention’s School Health Index (SHI) to promote collaboration between universities and urban school districts when developing adolescent health promotion initiatives. This article provides an overview of the real world contextual challenges and opportunities this type of collaboration can pose. METHODS The SHI and selected collaboration principles were used to facilitate partnership and increase stakeholder buy-in, which led to developing and implementing an eight year health promotion campaign, The Healthy Class of 2010 (HC 2010). RESULTS The focus on planning brought together key stakeholders and allowed for HC 2010 programming to take place despite the competing demands on the schools. The SHI allowed for input from stakeholders to develop campaign activities and inform school- and district-wide policy. Universities and school districts desiring to develop and implement school-based, adolescent health promotion programs should: 1) identify the hierarchical structure of the school district; 2) establish credibility for the program and the university staff; 3) emphasize the benefits to all partners; 4) maintain a cooperative partnership with teachers and administrators; 5) appreciate the need for planning; and, 6) provide as many resources as possible to on an already overburdened school system. CONCLUSIONS Promoting healthy behaviors among students is an important part of the fundamental mission of schools. HC 2010 underscored the significance of collaboration using the SHI in the development and implementation of this health promotion campaign with input from students, teachers, administrators and university partners.

Full Text Available Abstract Background Patients undergoing major orthopaedic surgery (MOS, such as total hip (THR or total knee replacement (TKR, are at high risk of developing venous thromboembolism (VTE. For thromboembolism prophylaxis, the oral anticoagulant rivaroxaban has recently been included in the German diagnosis related group (DRG system. However, the cost-effectiveness of rivaroxaban is still unclear from both the German statutory health insurance (SHI and the German hospital perspective. Objectives To assess the cost-effectiveness of rivaroxaban from the German statutory health insurance (SHI perspective and to analyse financial incentives from the German hospital perspective. Methods Based on data from the RECORD trials and German cost data, a decision tree was built. The model was run for two settings (THR and TKR and two perspectives (SHI and hospital per setting. Results Prophylaxis with rivaroxaban reduces VTE events (0.02 events per person treated after TKR; 0.007 after THR compared with enoxaparin. From the SHI perspective, prophylaxis with rivaroxaban after TKR is cost saving (€27.3 saving per patient treated. However, the cost-effectiveness after THR (€17.8 cost per person remains unclear because of stochastic uncertainty. From the hospital perspective, for given DRGs, the hospital profit will decrease through the use of rivaroxaban by €20.6 (TKR and €31.8 (THR per case respectively. Conclusions Based on our findings, including rivaroxaban for reimbursement in the German DRG system seems reasonable. Yet, adequate incentives for German hospitals to use rivaroxaban are still lacking.

In the SHiP beam-dump of the order of 1011 muons will be produced per second. An active muon-shield is used to magnetically deflect these muons out of the acceptance of the spectrom- eter. This note describes how this shield is modelled and optimized. The SHiP spectrometer is being re-optimized using a conical decay-vessel, and utilizing the possibility to magnetize part of the beam-dump shielding iron. A shield adapted to these new conditions is presented which is significantly shorter and lighter than the shield used in the Technical Proposal (TP), while showing a similar performance.

2016-05-01

Due to the insufficient data base the Federal Joint Committee (G-BA) had in 2009 after 7 years of deliberation decided to initiate consultation regarding ambulatory brachytherapy for localised prostate cancer for 10 years from social health insurance (SHI) benefits. The aim is to gain more findings by means of comparative studies. Based on the non-availability of clinical primary data of a methodologically acceptable level, it was analysed to what extent secondary data of the SHI may be used in order to arrive at valid conclusions for benefit aspects. As base approx. 8 million insured of TK with their data of cost reimbursement between 2006 and 2011 were considered. In SHI secondary data no clinical information regarding tumour stage and other prognostic factors are available. Therefore, a novel method with therapy-specific multisectoral inclusion and exclusion criteria, respectively, was developed in order to differentiate between localised and advanced tumours of the prostate. Overall survival, relapse-free survival, event-free survival and side-effects associated to prostate cancer were analysed. Out of 87 822 insured persons with the diagnosis prostate cancer, 795 with PBT, 10 936 with RP and 1 925 with EBRT were investigated in detail. The 4-year event-free survival rate was 73% for RP, 77% for PBT and 71% for EBRT. Many prostate cancer-specific side effects appeared already before intervention. Side effects of the intestinal tract (23.8%) and sexual impairments (26.5%) were more frequent for EBRT than for RP (17.1%/14.8%) and PBT (16.4%/13.2%). By means of SHI secondary data and adequate operationalisation important findings regarding relevant aspects of prostate cancer in healthcare research can be generated. However, these hold methodological limitations and are not suited to draw valid conclusions for benefit assessment. Based solely on SHI routine data valid statements regarding comparative benefit assessment are limited. Limitations could be

Full Text Available Objective: The study aimed at investigating the lifetime prevalence of 22 self-harm behaviors in bariatric surgery candidates (pre-bariatric surgery group; PSG compared to community controls with obesity (obese community group; OCG. Methods: The Self-Harm Inventory (SHI was administered to the PSG (n = 139, BMI ≥ 35 kg/m2 and to the OCG (n = 122, BMI ≥ 35 kg/m2. Results: Group comparison of cumulative SHI scores indicated a trend towards less endorsed SHI items in the PSG compared to the OCG (medianPSG = 1.00, IQRPSG = 2.00, medianOCG = 1.00, IQROCG = 2.25, U = 7.241, p = 0.033, η2 = 0.02. No significant group differences were found with regard to the rate of suicide attempts (12.4% vs. 9.4% for OCG vs. PSG. At least one type of lifetime self-harm behavior was admitted by 51.8% of the PSG and 63.9% of the OCG (χ2(1 = 3.91, p = 0.048. The results of logistic regressions using Firth's bias reduction method with at least one SHI item endorsed as dependent variable, group as categorical predictor (PSG as baseline, and age or BMI or PHQ-4 as continuous control variable indicated that only PHQ-4 had a positive effect on the odds ratio. Conclusion: The results suggest that self-harm (including suicidal attempts is not more prevalent in bariatric surgery candidates than in community control participants with obesity. Further studies are needed to investigate self-harm in bariatric surgery patients, prior and following surgery, compared to non-operated patients with obesity.

Can personality predict individual differences in brook trout spatial learning ability?

While differences in individual personality are common in animal populations, understanding the ecological significance of variation has not yet been resolved. Evidence suggests that personality may influence learning and memory; a finding that could improve our understanding of the evolutionary processes that produce and maintain intraspecific behavioural heterogeneity. Here, we tested whether boldness, the most studied personality trait in fish, could predict learning ability in brook trout. After quantifying boldness, fish were trained to find a hidden food patch in a maze environment. Stable landmark cues were provided to indicate the location of food and, at the conclusion of training, cues were rearranged to test for learning. There was a negative relationship between boldness and learning as shy fish were increasingly more successful at navigating the maze and locating food during training trials compared to bold fish. In the altered testing environment, only shy fish continued using cues to search for food. Overall, the learning rate of bold fish was found to be lower than that of shy fish for several metrics suggesting that personality could have widespread effects on behaviour. Because learning can increase plasticity to environmental change, these results have significant implications for fish conservation.

Does the Factor Structure of Military Sexual Stressors in Men Correspond to Women's? A Confirmatory Factor Analysis Using the Sexual Harassment Inventory.

Unwanted sexual stressors experienced by military men and women are associated with a host of negative physical and mental health problems. Government officials are making it a priority to put a stop to these unwanted sexual experiences. However, the measure typically used measures sexual stressors much better for women than for men. The purpose of the present study was to test the factor structure of an alternative measure, the Sexual Harassment Inventory (SHI), to examine whether sexual stressors experienced by men correspond to women's experiences. We used three preexisting datasets in which the SHI was used to assess active and former military members' sexual stressor experiences. We conducted an exploratory factor analysis to identify women's response patterns and a confirmatory factor analysis to determine whether men's response patterns corresponded to women's. Findings showed that the SHI has evidence of factorial validity in female service members and adequate, but not exceptional, factorial fit for male service members. It is imperative that more work be done to better understand how men experience and perceive potential military sexual stressors and how those perceptions and experiences compare to women's.

We revisit the production of baryon asymmetries in the minimal type I seesaw model with heavy Majorana singlets in the GeV range. In particular we include “washout” effects from scattering processes with gauge bosons, Higgs decays and inverse decays, besides the dominant top scatterings. We show that in the minimal model with two singlets, and for an inverted light neutrino ordering, future measurements from SHiP and neutrinoless double beta decay could in principle provide sufficient information to predict the matter-antimatter asymmetry in the universe. We also show that SHiP measurements could provide very valuable information on the PMNS CP phases.

We report quasi-two-dimensional (Q2D) itinerant electron magnetism in the layered Co-based shandites. Comprehensive magnetization measurements were performed using single crystals of Co3Sn2-xInxS2 (0 ≤ x ≤ 2) and Co3-yFeySn2S2 (0 ≤ y ≤ 0.5). The magnetic parameters of both systems; the Curie temperature TC, effective moment peff and spontaneous moment ps; exhibit almost identical variations against the In- and Fe-concentrations, indicating significance of the electron count on the magnetism in the Co-based shandite. The ferromagnetic-nonmagnetic quantum phase transition is found around xc ˜ 0.8. Analysis based on the extended Q2D spin fluctuation theory clearly reveals the highly Q2D itinerant electron character of the ferromagnetism in the Co-based shandites.

The effect of swift heavy ion (Xe 167 MeV) irradiation on polycrystalline SiC individually implanted with 360 keV Kr and Xe ions at room temperature to fluences of 2  ×  10 16 cm −2 and 1  ×  10 16 cm −2 respectively, was investigated using transmission electron microscopy (TEM), Raman spectroscopy and Rutherford backscattering spectrometry (RBS). Implanted specimens were each irradiated with 167 MeV Xe +26 ions to a fluence of 8.3  ×  10 14 cm −2 at room temperature. It was observed that implantation of 360 keV Kr and Xe ions individually at room temperature amorphized the SiC from the surface up to a depth of 186 and 219 nm respectively. Swift heavy ion (SHI) irradiation reduced the amorphous layer by about 27 nm and 30 nm for the Kr and Xe samples respectively. Interestingly, the reduction in the amorphous layer was accompanied by the appearance of randomly oriented nanocrystals in the former amorphous layers after SHI irradiation in both samples. Previously, no similar nanocrystals were observed after SHI irradiations at electron stopping powers of 33 keV nm −1 and 20 keV nm −1 to fluences below 10 14 cm −2 . Therefore, our results suggest a fluence threshold for the formation of nanocrystals in the initial amorphous SiC after SHI irradiation. Raman results also indicated some annealing of radiation damage after swift heavy ion irradiation and the subsequent formation of small SiC crystals in the amorphous layers. No diffusion of implanted Kr and Xe was observed after swift heavy ion irradiation. (paper)

The traditional separation of health care into sectors in Germany causes communication problems that hinder continuous, patient-oriented care. This is most evident in the transition from inpatient to outpatient care. That said, there are also breaks in the flow of information, a lack of supply, or even incorrect information flowing within same-sector care. The transition from a division of functions into sectors to a patient-oriented process represents a change in the paradigm of health care that can only be successfully completed with considerable effort. Germany's statutory health insurance (SHI) funds play a key role here, as they are the contracting parties as well as the financiers of integrated care, and are strategically located at the center of the development process.The objective of this article is to explore how Germany's SHI funds view integrated care, what they regard as being the drivers of and barriers to transitioning to such a system, and what recommendations they can provide with regard to the further development of integrated care. For this purpose semi-structured interviews with board members and those responsible for implementing integrated care into the operations of ten SHI funds representing more than half of Germany's SHI-insured population were conducted. According to the interviewees, a better framework for integrated care urgently needs to be developed and rendered more receptive to innovation.Only in this way will the widespread stagnation of the past several years be overcome. The deregulation of § 140a-d SGB V and the establishment of a uniform basis for new forms of care in terms of a new innovation clause are among the central recommendations of this article. The German federal government's innovation fund was met with great hope, but also implied risks. Nonetheless, the new law designed to strengthen health care overall generated high expectations.

160 MeV Ni12+ ion irradiation effects on the structural, optical and electrical properties of spherical polypyrrole nanoparticles

Highlights: • Upon SHI irradiation the average diameters of PPy nanoparticles increases. • Crystallinity of PPy nanoparticles increases with increasing ion fluence. • IR active vibrational bands have different cross sections for SHI irradiation. • Upon SHI irradiation optical band gap energy of PPy nanoparticles decreases. • Upon SHI irradiation thermal stability of PPy nanoparticles increases. -- Abstract: In this study we report 160 MeV Ni 12+ swift heavy ion irradiation induced enhancement in the structural, optical and electrical properties of spherical polypyrrole (PPy) nanoparticles. High resolution transmission electron microscope results show that the pristine PPy nanoparticles have an average diameter of 11 nm while upon irradiation the average diameter increases to 18 nm at the highest ion fluence of 1 × 10 12 ions/cm 2 . X-ray diffraction studies show an enhancement of crystallinity and average crystallite size of PPy nanoparticles with increasing fluence. Studies of Fourier transform infrared spectra suggest the structural modifications of different functional groups upon irradiation. It also reveals that different functional groups have different sensitivity to irradiation. The infrared active N–H vibrational band at 3695 cm −1 is more sensitive to irradiation with a formation cross-section of 5.77 × 10 −13 cm 2 and effective radius of 4.28 nm. The UV–visible absorption spectra of PPy nanoparticles show that the absorption band undergoes a red shift with increasing fluence. Moreover upon irradiation the optical band gap energy decreases and Urbach’s energy increases with fluence. Thermo-gravimetric analysis studies suggest that upon irradiation the thermal stability of PPy nanoparticles increases which may be attributed to their enhanced crystallinity. Current–voltage characteristics of PPy nanoparticles exhibit non-Ohmic, symmetric behavior which increases with fluence

This research addressed the long term goals of understanding the assembly and organization of hydrogenase enzymes, of reducing them in size and complexity, of determining structure/function relationships, including energy conservation via charge separation across membranes, and in screening for novel H2 catalysts. A key overall goal of the proposed research was to define and characterize minimal hydrogenases that are produced in high yields and are oxygen-resistant. Remarkably, in spite of decades of research carried out on hydrogenases, it is not possible to readily manipulate or design the enzyme using molecular biology approaches since a recombinant form produced in a suitable host is not available. Such resources are essential if we are to understand what constitutes a “minimal” hydrogenase and design such catalysts with certain properties, such as resistance to oxygen, extreme stability and specificity for a given electron donor. The model system for our studies is Pyrococcus furiosus, a hyperthermophile that grows optimally at 100°C, which contains three different nickel-iron [NiFe-] containing hydrogenases. Hydrogenases I and II are cytoplasmic while the other, MBH, is an integral membrane protein that functions to both evolve H2 and pump protons. Three important breakthroughs were made during the funding period with P. furiosus soluble hydrogenase I (SHI). First, we produced an active recombinant form of SHI in E. coli by the co-expression of sixteen genes using anaerobically-induced promoters. Second, we genetically-engineered P. furiosus to overexpress SHI by an order of magnitude compared to the wild type strain. Third, we generated the first ‘minimal’ form of SHI, one that contained two rather than four subunits. This dimeric form was stable and active, and directly interacted with a pyruvate-oxidizing enzyme with any intermediate electron carrier. The research resulted in five peer-reviewed publications.

Some specific features of a surface-screw plasma instability in semiconductors

A numerical analysis of the dispersion relation has been carried out, which enables to discover some new peculiarities in the behaviour of the surface helical instability (SHI) of a semiconductor plasma. To simplify the dispersion relation a semiconductor with nearly equal electron and hole mobilities has been considered. The dependences of threshold characteristics of SHI on a magnetic field H for different angular harmonics are represented graphically. A comparison of the formulas obtained shows that the approximation of truncated series yields an incorrect qualitative dependence of the wavelength on H, whereas asymptotic formulas in the range of strong magnetic fields yield not only a correct qualitative dependence of the threshold characteristics on H, but also a good quantitative agreement

Ultrasound contrast agents (UCAs) are small micro-bubbles that behave nonlinearly when exposed to an ultrasound wave. This nonlinear behavior can be observed through the generated higher harmonics in a back-scattered echo. In past years several techniques have been proposed to detect or image harmonics produced by UCAs. In these proposed works, the harmonics generated in the medium during the propagation of the ultrasound wave played an important role, since these harmonics compete with the harmonics generated by the micro-bubbles. We present a method for the reduction of the second harmonic generated during nonlinear-propagation-dubbed second harmonic inversion (SHI). A general expression for the suppression signals is also derived. The SHI technique uses two pulses, p' and p'', of the same frequency f{sub 0} and the same amplitude P{sub 0} to cancel out the second harmonic generated by nonlinearities of the medium. Simulations show that the second harmonic is reduced by 40 dB on a large axial range. Experimental SHI B-mode images, from a tissue-mimicking phantom and UCAs, show an improvement in the agent-to-tissue ratio (ATR) of 20 dB compared to standard second harmonic imaging and 13 dB of improvement in harmonic power Doppler.

The authors have cloned malignant cells carrying specific antigens associated with ovarian cancer (OVC) and malignant lymphoma (ML) from BS-SHI-4M cells, a line derived from a 1-methyl-3-nitro-1-nitrosoguanidine-treated B-lymphoblastoid cell line isolated from a patient with Bloom syndrome. Since BS-SHI-4M cells react with sera from various individual cancer patients at relatively low frequencies (2-9%), as detected by an indirect immunofluorescence technique, cell clones that specifically react with sera from patients with OVC and ML were separated by the panning method in which polystyrene dishes were coated with sera from OVC and ML patients and cells with the corresponding antigens bound to the dishes. Subsequent cloning by limiting dilution provided cell clones highly enriched for OVC- and ML-associated antigens. Karyotype analyses revealed that cell clones with OVC and ML antigens had common marker chromosomes. Interestingly, in cell clones with a strong OVC antigen response, the distal part of the Y chromosome (Yq11) was missing in 100% of the cells. Therefore the cell line BS-SHI-4M appears to be a reservoir of cell clones each of which carries a specific tumor antigen and thus provides a potential tool for rapid serological diagnosis of cancer

While differences in individual personality are common in animal populations, understanding the ecological significance of variation has not yet been resolved. Evidence suggests that personality may influence learning and memory; a finding that could improve our understanding of the evolutionary processes that produce and maintain intraspecific behavioural heterogeneity. Here, we tested whether boldness, the most studied personality trait in fish, could predict learning ability in brook trout. After quantifying boldness, fish were trained to find a hidden food patch in a maze environment. Stable landmark cues were provided to indicate the location of food and, at the conclusion of training, cues were rearranged to test for learning. There was a negative relationship between boldness and learning as shy fish were increasingly more successful at navigating the maze and locating food during training trials compared to bold fish. In the altered testing environment, only shy fish continued using cues to search for food. Overall, the learning rate of bold fish was found to be lower than that of shy fish for several metrics suggesting that personality could have widespread effects on behaviour. Because learning can increase plasticity to environmental change, these results have significant implications for fish conservation. Copyright © 2016 Elsevier B.V. All rights reserved.

2011-01-01

In the present work pure and metal ions (Co and Fe) doped hydroxyapatite (HAp) thick films have been successfully utilized to improve the structural, morphological and gas sensing properties. Nanocrystalline HAp powder is synthesized by wet chemical precipitation route, and ion exchange process is employed for addition of Co and Fe ions in HAp matrix. Moreover, swift heavy ion irradiation (SHI) technique is used to modify the surface of pure and metal ion exchanged HAp with various ion fluence. The structural investigation of pure and metal ion exchanged HAp thick films are carried out using X-ray diffraction and the presence of functional group is observed by means FTIR spectroscopy. Furthermore, surface morphology is visualized by means of SEM and AFM analysis. CO gas sensing study is carried out for, pure and metal ions doped, HAp thick films with detail investigation on operating temperature, response/recovery time and gas uptake capacity. The surface modifications of sensor matrix by SHI enhance the gas response, response/recovery and gas uptake capacity. The significant observation is here to note that, addition of Co and Fe in HAp matrix and surface modification by SHI improves the sensing properties of HAp films drastically resulting in gas sensing at relatively lower temperatures.

Damage formation and annealing in InP due to swift heavy ions

International Nuclear Information System (INIS)

Kamarou, A.; Wesch, W.; Wendler, E.; Klaumuenzer, S.

2004-01-01

Virgin and pre-damaged InP samples were irradiated at room temperature (RT) and at liquid nitrogen temperature (LNT) with different fluences of 140 MeV Kr, 390 MeV Xe and 600 MeV Au ions. The pre-damaging was performed with 600 keV Ge ions at LNT to obtain different damage levels. The samples were analysed by means of Rutherford backscattering spectrometry (RBS) in random and channelling geometry. A relatively weak damage accumulation in virgin InP and a very significant defect annealing in pre-damaged InP occurs due to 140 MeV Kr irradiation. The damaging of virgin InP with 390 MeV Xe and 600 MeV Au is much more efficient in comparison with that of 140 MeV Kr. Further, annealing of the pre-damaged InP due to 390 MeV Xe irradiation is hardly visible. At LNT InP appears to be much more radiation-resistant to swift heavy ion (SHI) irradiation than at RT. Our results show that during SHI irradiation of InP both damage formation and damage annealing occur simultaneously. Whether the first or the second one plays a more important role depends on the SHI mass and energy

In this study, the authors investigated the relationship between compulsive buying and borderline personality disorder (BPD) symptomatology--two disorders possibly linked through impulsivity. Using a survey methodology in a cross-sectional consecutive sample of nonemergent female outpatients from an obstetrics/gynecology clinic, the authors assessed compulsive buying with the compulsive buying scale (CBS) and BPD symptomatology through the BPD scale of the personality diagnostic questionnaire-4 (PDQ-4) and the self-harm Inventory (SHI). In this sample, 8% of Caucasian women and 9% of African-American women scored positively for compulsive buying. The correlations between scores on the CBS and the PDQ-4 and SHI were 0.43 and 0.41, respectively-both statistically significant at the p buying and BPD, particularly among African-American women.

Present study demonstrates the role of metal-insulator interface and ion irradiation induced defects on the ferromagnetic properties of the non-magnetic materials. Magnetic properties of the Pd nanoparticles(NPs) embedded in the a-silica matrix synthesized using atom beam sputtering technique, were determined using SQUID magnetometry measurements which showed that ferromagnetic response of Pd increased by 3.5 times on swift heavy ion(SHI) irradiation. The ferromagnetic behavior of the as-deposited Pd NPs is due to strain induced by the surrounding matrix and modification in the electronic structure at the Pd-silica interface as revealed by insitu XRD and XPS investigations, respectively. The defects created by the SHI bombardment are responsible for enhancement of the magnetization in the Pd NPs.

La{sub 1-x}Sr{sub x}Co{sub 1-y}FeyO{sub 3-d}elta oxides are good candidates for solid oxide fuel cell (SOFC) cathodes because these materials present high ionic and electronic conductivity, and compatibility with Cerium Gadolinium Oxide (CGO) electrolytes allowing a lower operation temperature. In this work, we report the synthesis of La{sub 0.4}Sr{sub 0.6}Co{sub 0.8}Fe{sub 0.2}O{sub 3-d}elta (LSCF) nanotubes prepared by a porous polycarbonate membrane approach, obtaining different microstructures depending on sintering conditions. The structure and morphology of the nanotubes and deposited films were characterized by X-ray diffraction, transmission and scanning microscopy. Finally, we obtained nanostructured films of vertically aligned LSCF tubes deposited over the whole surface of CGO pellets with diameter up to 2.5cm in a direct and single step process.

Manufacturability of compact synchrotron mirrors

Science.gov (United States)

Douglas, Gary M.

1997-11-01

While many of the government funded research communities over the years have put their faith and money into increasingly larger synchrotrons, such as Spring8 in Japan, and the APS in the United States, a viable market appears to exist for smaller scale, research and commercial grade, compact synchrotrons. These smaller, and less expensive machines, provide the research and industrial communities with synchrotron radiation beamline access at a portion of the cost of their larger and more powerful counterparts. A compact synchrotron, such as the Aurora-2D, designed and built by Sumitomo Heavy Industries, Ltd. of japan (SHI), is a small footprint synchrotron capable of sustaining 20 beamlines. Coupled with a Microtron injector, with 150 MeV of injection energy, an entire facility fits within a 27 meter [88.5 ft] square floorplan. The system, controlled by 2 personal computers, is capable of producing 700 MeV electron energy and 300 mA stored current. Recently, an Aurora-2D synchrotron was purchased from SHI by the University of Hiroshima. The Rocketdyne Albuquerque Operations Beamline Optics Group was approached by SHI with a request to supply a group of 16 beamline mirrors for this machine. These mirrors were sufficient to supply 3 beamlines for the Hiroshima machine. This paper will address engineering issues which arose during the design and manufacturing of these mirrors.

Investigation of Au9+ swift heavy ion irradiation on CdS/CuInSe2 thin films

International Nuclear Information System (INIS)

Joshi, Rajesh A.; Taur, Vidya S.; Singh, Fouran; Sharma, Ramphal

2013-01-01

In the present manuscript we report about the preparation of CdS/CuInSe 2 heterojunction thin films by chemical ion exchange method and investigation of 120 MeV Au 9+ swift heavy ions (SHI) irradiation effect on its physicochemical as well as optoelectronic properties. These pristine (as grown) samples are irradiated with 120 MeV Au 9+ SHI of 5×10 11 and 5×10 12 ions/cm 2 fluencies and later on characterized for structural, compositional, morphological, optical and I–V characteristics. X-ray diffraction (XRD) pattern obtained from pristine and irradiated films shows considerable modifications in peak intensity as well as rising of some new peaks, corresponding to In 2 Se 3 , Cu 3 Se 2 and CuIn 2 Se 3 materials. Transmission electron microscope (TEM) images show decrease in grain size upon increase in irradiation ion fluencies, which is also supported from the observation of random and uneven distribution of nano-grains as confirmed through scanning electron microscope (SEM) images. Presence of Cd, Cu, In, S and Se in energy dispersive X-ray spectrum analysis (EDAX) confirms the expected and observed elemental composition in thin films, the absorbance peaks are related to band to band transitions and spin orbit splitting while energy band gap is observed to increase from 1.36 for pristine to 1.53 eV for SHI irradiated thin films and I–V characteristics under illumination to 100 mW/cm 2 light source shows enhancement in conversion efficiency from 0.26 to 1.59% upon irradiation. - Highlights: • Nanostructured CdS/CuInSe 2 can be grown by chemical ion exchange method. • Physicochemical and optoelectronic properties can be modified by 120 MeV Au 9+ SHI Irradiation. • Solar energy conversion efficiency improved from 0.26 to 1.59% in CdS/CuInSe 2 upon irradiation

Study of low vibration 4 K pulse tube cryocoolers

Xu, Mingyao; Nakano, Kyosuke; Saito, Motokazu; Takayama, Hirokazu; Tsuchiya, Akihiro; Maruyama, Hiroki

2012-06-01

Sumitomo Heavy Industries, Ltd. (SHI) has been continuously improving the efficiency and reducing the vibration of a 4 K pulse tube cryocooler. One advantage of a pulse tube cryocooler over a GM cryocooler is low vibration. In order to reduce vibration, both the displacement and the acceleration have to be reduced. The vibration acceleration can be reduced by splitting the valve unit from the cold head. One simple way to reduce vibration displacement is to increase the wall thickness of the tubes on the cylinder. However, heat conduction loss increases while the wall thickness increases. To overcome this dilemma, a novel concept, a tube with non-uniform wall thickness, is proposed. Theoretical analysis of this concept, and the measured vibration results of an SHI lowvibration pulse tube cryocooler, will be introduced in this paper.

Full Text Available Blended cathode materials made by mixing LiFePO4 (LFP with LiMnPO4 (LMP or LiNi1/3Mn1/3Co1/3O2 (NMC that exhibit either high specific energy and high rate capability were investigated. The layered blend LMP–LFP and the physically mixed blend NMC–LFP are evaluated in terms of particle morphology and electrochemical performance. Results indicate that the LMP–LFP (66:33 blend has a better discharge rate than the LiMn1−yFeyPO4 with the same composition (y = 0.33, and NMC–LFP (70:30 delivers a remarkable stable capacity over 125 cycles. Finally, in situ voltage measurement methods were applied for the evaluation of the phase evolution of blended cathodes and gradual changes in cell behavior upon cycling. We also discuss through these examples the promising development of blends as future electrodes for new generations of Li-ion batteries.

China opens the door

Energy Technology Data Exchange (ETDEWEB)

Starke, K.

1997-01-01

The door to China`s vast market for power generation was opened a bit further for foreign firms in November. That is when power ministry head Shi Dazhen said the country would rely on overseas investors for 20 percent of the funding needed to boost output--double the amount foreigners were previously allowed to contribute. Through 1995, foreigners invested $12.2 billion in China`s electricity industry, accounting for 10 percent of total investment. According to Shi, foreign investors will be asked to provide about $17 billion of the $84 billion China plans to invest in the sector over the next five years. Under China`s Ninth Five-Year Plan (1996-2000), the government aims to boost the country`s power generation capacity at the rate of 15,000 MW to 20,000 MW annually by the year 2000. Since China`s public external debt balance already exceeds $80 billion, however, the government would seem to have little choice but to allow foreigners a greater role. Shi also said that foreigners would be allowed 100 percent ownership of PRC power projects. This is discouraged under China`s current industry guidelines. It is, however, expected to be permitted under China`s first build-operate-transfer (BOT) law, which was anticipated by the end of 1996, says Susan Urkevich, director of project finance at HSBC Investment Bank Asia in Hong Kong. Indeed, China`s first BOT is already happening.

Model of wet chemical etching of swift heavy ions tracks

Gorbunov, S. A.; Malakhov, A. I.; Rymzhanov, R. A.; Volkov, A. E.

2017-10-01

A model of wet chemical etching of tracks of swift heavy ions (SHI) decelerated in solids in the electronic stopping regime is presented. This model takes into account both possible etching modes: etching controlled by diffusion of etchant molecules to the etching front, and etching controlled by the rate of a reaction of an etchant with a material. Olivine ((Mg0.88Fe0.12)2SiO4) crystals were chosen as a system for modeling. Two mechanisms of chemical activation of olivine around the SHI trajectory are considered. The first mechanism is activation stimulated by structural transformations in a nanometric track core, while the second one results from neutralization of metallic atoms by generated electrons spreading over micrometric distances. Monte-Carlo simulations (TREKIS code) form the basis for the description of excitations of the electronic subsystem and the lattice of olivine in an SHI track at times up to 100 fs after the projectile passage. Molecular dynamics supplies the initial conditions for modeling of lattice relaxation for longer times. These simulations enable us to estimate the effects of the chemical activation of olivine governed by both mechanisms. The developed model was applied to describe chemical activation and the etching kinetics of tracks of Au 2.1 GeV ions in olivine. The estimated lengthwise etching rate (38 µm · h-1) is in reasonable agreement with that detected in the experiments (24 µm · h-1).

The proton therapy system for Massachusetts General Hospital's Northeast Proton Therapy Center

Jongen, Y.

1996-01-01

In 1989, two companies, Ion Beam Applications in Belgium (IBA) and Sumitomo Heavy Industries in Japan (SHI) started to design proton therapy equipments based on cyclotrons. In 1991, SHI and IBA decided to join their development efforts in this field. In 1993, the Massachusetts General Hospital (MGH), pioneer in the field of proton therapy, launched an international request for proposals for the procurement of an in-hospital proton therapy facility. The 18 may 1994, the contract was signed with a team of industries led by IBA, including also SHI and General Atomics (GA) of California. The proposed system is based on a fixed energy, isochronous cyclotron, followed by an energy degrader and an energy selection system. The variable energy beam can be rapidly switched in any one of three treatment rooms. Two rooms are equipped with large isocentric gantries and robotic patient positioners allowing to direct the proton beam within the patient from any direction. The third room is equipped with fixed horizontal beam. The complete system is computer controlled by a distributed network of computers, programmable logic controllers and workstations. This computer control allows to change the energy in one treatment room is less than two second, a performance matching or exceeding the flexibility offered by synchrotrons. The system is now built and undergoing factory tests. The beam has been accelerated to full energy in the cyclotron, and beam extraction tests are underway. Installation in the hospital building will take place in 1997. (author)

Quantitative analysis of the epitaxial recrystallization effect induced by swift heavy ions in silicon carbide

International Nuclear Information System (INIS)

Benyagoub, A.

2015-01-01

This paper discusses recent results on the recrystallization effect induced by swift heavy ions (SHI) in pre-damaged silicon carbide. The recrystallization kinetics was followed by using increasing SHI fluences and by starting from different levels of initial damage within the SiC samples. The quantitative analysis of the data shows that the recrystallization rate depends drastically on the local amount of crystalline material: it is nil in fully amorphous regions and becomes more significant with increasing amount of crystalline material. For instance, in samples initially nearly half-disordered, the recrystallization rate per incident ion is found to be 3 orders of magnitude higher than what it is observed with the well-known IBIEC process using low energy ions. This high rate can therefore not be accounted for by the existing IBIEC models. Moreover, decreasing the electronic energy loss leads to a drastic reduction of the recrystallization rate. A comprehensive quantitative analysis of all the experimental results shows that the SHI induced high recrystallization rate can only be explained by a mechanism based on the melting of the amorphous zones through a thermal spike process followed by an epitaxial recrystallization initiated from the neighboring crystalline regions if the size of the latter exceeds a certain critical value. This quantitative analysis also reveals that recent molecular dynamics calculations supposed to reproduce this phenomenon are wrong since they overestimated the recrystallization rate by a factor ∼40.

Child shyness and peer likeability: The moderating role of pragmatics and vocabulary.

Science.gov (United States)

Cheung, Hoi Shan; Elliott, John M

2017-11-01

The association between shyness and children's likeability by peers was examined, with pragmatic difficulty and receptive and expressive vocabularies as moderators. Participants were 164 preschoolers (72 boys, 92 girls) between 52 and 79 months old in Singapore. A cross-informant methodology was used, with peers and teachers contributing to separate peer likeability ratings. The findings highlighted a conceptual distinction between peer- and teacher-rated likeability by peers. For the latter only, a 3-way interaction involving shyness, vocabulary, and pragmatic difficulty was found, indicating that for shy children with low vocabulary scores, those who experienced less pragmatic difficulty tended to be seen by teachers as more well-liked by peers than those with more pragmatic difficulty. This suggests that pragmatic skills may serve a protective function especially for shy children with poor vocabulary skills. Statement of contribution What is already known on this subject? Child shyness is related to poorer peer acceptance and social competence Expressive vocabulary and pragmatic competence each has a buffering effect for shy children What the present study adds? Shyness is related to poorer peer likeability as assessed by teachers Shyness is unrelated to peer likeability as assessed by same- or different-sex peers Pragmatic skills buffer the effects of teacher-rated shyness only for children with poor receptive and expressive vocabularies The buffering effect of language ability is shown in a multilingual educational context. © 2017 The British Psychological Society.

Bowker, Julie C; Ojo, Adesola Adebusola; Bowker, Matthew H

2016-02-01

The study of social withdrawal subtypes is no longer limited to Western societies but has extended to non-Western countries, such as China. This study considers, for the first time, social withdrawal subtypes in an African country (Nigeria) by examining emerging adults' (N = 151; 54% female; Mage = 19.92 years, SD = 2.54) perceptions, attitudes, and responses to shy, unsociable, and socially competent behaviors. Results revealed that Nigerian emerging adults perceived significant differences between shy, unsociable, and socially competent behavior in several ways incommensurate with participants of previous studies conducted in North America, Europe, and China. Findings highlight the diversity of social meanings attached to social withdrawal in non-Western societies, and point to the need for additional research on social withdrawal and its perception in Africa.

An important input for the interpretation of the measurements of the SHiP ex- periment is a good knowledge of the differential charm production cross section, including cascade production. This is a proposal to measure the associated charm production cross section, employing the SPS 400 GeV/c proton beam and a replica of the first two interaction lengths of the SHiP target. The detection of the produc- tion and decay of charmed hadron in the target will be performed through nuclear emulsion films, employed in an Emulsion Cloud Chamber target structure. In order to measure charge and momentum of decay daughters, we intend to build a mag- netic spectrometer using silicon pixel, scintillating fibre and drift tube detectors. A muon tagger will be built using RPCs. An optimization run is scheduled in 2018, while the full measurement will be performed after the second LHC Long Shutdown.

Physico-chemical characterization of polyethylene of ultra high molecular weight modified with gamma irradiation and heavy ions

International Nuclear Information System (INIS)

Lagarde, M; Del Grosso, M; Fasce, D; Dommarco, R; Laino, S; Fasce, L.A

2012-01-01

The ultra high molecular weight polyethylene (UHMWPE) is a biomaterial widely used in total joint replacement. In this work, the effect of two different irradiation techniques on UHMWPE is analyzed. One technique involves gamma irradiation (γ) followed by a thermal treatment, thus modifying the material bulk. The other implies swift heavy ion irradiation (SHI), which have an effect only on the near surface layers. The surface nanomechanical properties are evaluated from depth sensing indentation experiments, while changes in crystallinity and chemical structure are determined by DSC and Raman spectroscopy. The results show that even when both techniques are able to improve the UHMWPE wear behavior, the effect on other mechanical properties and molecular structure modification is different. The γ irradiated sample exhibits lower crystallinity, hardness and modulus than the pristine UHMWPE, while the SHI irradiated sample exhibits higher crystallinity and enhanced mechanical properties than the later

Sleep and the price of plasticity: from synaptic and cellular homeostasis to memory consolidation and integration.

Science.gov (United States)

Tononi, Giulio; Cirelli, Chiara

2014-01-08

Sleep is universal, tightly regulated, and its loss impairs cognition. But why does the brain need to disconnect from the environment for hours every day? The synaptic homeostasis hypothesis (SHY) proposes that sleep is the price the brain pays for plasticity. During a waking episode, learning statistical regularities about the current environment requires strengthening connections throughout the brain. This increases cellular needs for energy and supplies, decreases signal-to-noise ratios, and saturates learning. During sleep, spontaneous activity renormalizes net synaptic strength and restores cellular homeostasis. Activity-dependent down-selection of synapses can also explain the benefits of sleep on memory acquisition, consolidation, and integration. This happens through the offline, comprehensive sampling of statistical regularities incorporated in neuronal circuits over a lifetime. This Perspective considers the rationale and evidence for SHY and points to open issues related to sleep and plasticity. Copyright © 2014 Elsevier Inc. All rights reserved.

Cost-effectiveness of tiotropium versus salmeterol: the POET-COPD trial.

2013-03-01

The aim of this study was to perform a 1-yr trial-based cost-effectiveness analysis (CEA) of tiotropium versus salmeterol followed by a 5-yr model-based CEA. The within-trial CEA, including 7,250 patients with moderate to very severe chronic obstructive pulmonary disease (COPD), was performed alongside the 1-yr international randomised controlled Prevention of Exacerbations with Tiotropium (POET)-COPD trial comparing tiotropium with salmeterol regarding the effect on exacerbations. Main end-points of the trial-based analysis were costs, number of exacerbations and exacerbation days. The model-based analysis was conducted to extrapolate results to 5 yrs and to calculate quality-adjusted life years (QALYs). 1-yr costs per patient from the German statutory health insurance (SHI) perspective and the societal perspective were €126 (95% uncertainty interval (UI) €55-195) and €170 (95% UI €77-260) higher for tiotropium, respectively. The annual number of exacerbations was 0.064 (95% UI 0.010-0.118) lower for tiotropium, leading to a reduction in exacerbation-related costs of €87 (95% UI €19-157). The incremental cost-effectiveness ratio was €1,961 per exacerbation avoided from the SHI perspective and €2,647 from the societal perspective. In the model-based analyses, the 5-yr costs per QALY were €3,488 from the SHI perspective and €8,141 from the societal perspective. Tiotropium reduced exacerbations and exacerbation-related costs, but increased total costs. Tiotropium can be considered cost-effective as the resulting cost-effectiveness ratios were below commonly accepted willingness-to-pay thresholds.

Renazzo-type carbonaceous (CR) chondrites are accretionary breccias that formed last. As such they are ideal samples to study precompaction exposures to cosmic rays. Here, we present noble gas data for 24 chondrules and 3 dark inclusion samples (DIs) from Shişr 033 (CR2). The meteorite was selected based on the absence of implanted solar wind noble gases and an anomalous oxygen isotopic composition of the DIs; the oxygen isotopes match those in CV3 and CO3 chondrites. Our samples contain variable mixtures of galactic cosmic ray (GCR)-produced cosmogenic noble gases and trapped noble gases of presolar origin. Remarkably, all chondrules have cosmogenic 3He and 21Ne concentrations up to 4.3 and 7.1 times higher than the DIs, respectively. We derived an average 3He-21Ne cosmic ray exposure (CRE) age for Shişr 033 of 2.03 ± 0.20 Ma (2 SD) and excesses in cosmogenic 3He and 21Ne in chondrules (relative to the DIs) in the range (in 10-8 cm3STP/g) 3.99-7.76 and 0.94-1.71, respectively. Assuming present-day GCR flux density, the excesses translate into average precompaction 3He-21Ne CRE ages of 3.1-27.3 Ma depending on the exposure geometry. The data can be interpreted assuming a protracted storage of a single chondrule generation prior to the final assembly of the Shişr 033 parent body in a region of the disk transparent to GCRs.

Lusutrombopag (S-888711), an oral small-molecule thrombopoietin receptor (TPOR) agonist, has gained first approval as a drug to treat thrombocytopenia of chronic liver disease in patients undergoing elective invasive procedures in Japan. Preclinical studies were performed to evaluate its efficacy against megakaryopoiesis and thrombopoiesis. To investigate the proliferative activity and efficacy of megakaryocytic colony formation via human TPOR, lusutrombopag was applied to cultured human c-Mpl-expressing Ba/F3 (Ba/F3-hMpl) cells and human bone marrow-derived CD34-positive cells, respectively. Lusutrombopag caused a robust increase in Ba/F3-hMpl cells by activating pathways in a manner similar to that of thrombopoietin and induced colony-forming units-megakaryocyte and polyploid megakaryocytes in human CD34-positive cells. Because lusutrombopag has high species specificity for human TPOR, there was no suitable experimental animal model for drug evaluation, except for immunodeficient mouse-based xenograft models. Therefore, a novel genetically modified knock-in mouse, TPOR-Ki/Shi, was developed by replacing mouse Mpl with human-mouse chimera Mpl. In TPOR-Ki/Shi mice, lusutrombopag significantly increased circulating platelets in a dose-dependent manner during 21-day repeated oral administration. Histopathological study of the TPOR-Ki/Shi mice on day 22 also revealed a significant increase in megakaryocytes in the bone marrow. These results indicate that lusutrombopag acts on human TPOR to upregulate differentiation and proliferation of megakaryocytic cells, leading to platelet production.

Kinetic Ising model in a time-dependent oscillating external magnetic field: effective-field theory

International Nuclear Information System (INIS)

Deviren, Bayram; Canko, Osman; Keskin, Mustafa

2010-01-01

Recently, Shi et al. [2008 Phys. Lett. A 372 5922] have studied the dynamical response of the kinetic Ising model in the presence of a sinusoidal oscillating field and presented the dynamic phase diagrams by using an effective-field theory (EFT) and a mean-field theory (MFT). The MFT results are in conflict with those of the earlier work of Tomé and de Oliveira, [1990 Phys. Rev. A 41 4251]. We calculate the dynamic phase diagrams and find that our results are similar to those of the earlier work of Tomé and de Oliveira; hence the dynamic phase diagrams calculated by Shi et al. are incomplete within both theories, except the low values of frequencies for the MFT calculation. We also investigate the influence of external field frequency (ω) and static external field amplitude (h 0 ) for both MFT and EFT calculations. We find that the behaviour of the system strongly depends on the values of ω and h 0 . (general)

The Relationship Between Online Video Game Involvement and Gaming-Related Friendships Among Emotionally Sensitive Individuals

Science.gov (United States)

Domahidi, Emese; Quandt, Thorsten

2014-01-01

Abstract Some researchers believe that online gaming spaces can be socially accommodating environments for socially inhibited individuals, such as the socially inept, socially anxious, or shy. While previous research has examined, and found, significant links between these populations and online video game play, it remains unknown to what extent these spaces are contributing to tangible social benefits for the socially inhibited. The current study addresses this question by evaluating the link between gaming-related friendships and shyness, as quantified by emotional sensitivity. Drawing from a representative sample of German game players, the results indicate that emotionally sensitive players are using online gaming spaces differently from their less emotionally sensitive counterparts and reporting tangible differences in their in-game friendship networks. This suggests that online games hold the potential to be socially advantageous for shy individuals by allowing them to overcome their traditional social difficulties and generate new friendships as well as strengthen old ones.

"ESSAY ON CI" BY LI QINGZHAO

Full Text Available The article presents the first Russian translation of "Essay on Ci" with detailed comments. It was written by the outstanding Chinese poetess Li Qingzhao and considered to be the first theoretical treatise dedicated to genre ci. The article revealed that the poetess used three strategies to make a genre demarcation: to legitimise, dichotomise and historicise. To legitimise means to justify that ci is a genre of poetry by identifying the same traits with official poetry shi (e.g. using the classical quotations and allusions. To dichotomise is to determine a core element of genre and oppose it to the other element identifying the similar genre (e.g. music separates ci from shi. To historicise is to develop or discover the unique historical past (e.g. the source of ci is in antiquity. The article also examined the strategy to invent classics: Li Qingzhao wrote the apophatic history of genre ci pointing not to the merits but weaknesses of her predecessors.

2017-07-01

The modification in various properties of thin films using high energetic ion beam is an exciting area of basic and applied research in semiconductors. In the present investigations, cadmium selenide (CdSe) thin films were deposited on ITO substrate using electrodeposition technique. To study the swift heavy ion (SHI) induced effects, the deposited thin films were irradiated with 120 MeV heavy Ag9+ ions using pelletron accelerator facility at IUAC, New Delhi, India. Structural phase transformation in CdSe thin film from metastable cubic phase to stable hexagonal phase was observed after irradiation leading to decrease in the band gap from 2.47 eV to 2.12 eV. The phase transformation was analyzed through X-ray diffraction patterns. During SHI irradiation, Generation of high temperature and pressure by thermal spike along the trajectory of incident ions in the thin films might be responsible for modification in the properties of thin films.[Figure not available: see fulltext.

On the self-serving function of social anxiety: shyness as a self-handicapping strategy.

Science.gov (United States)

Snyder, C R; Smith, T W; Augelli, R W; Ingram, R E

1985-04-01

We tested the hypothesis that socially anxious or shy individuals use their anxiety symptoms as a strategy to control attributions made about their performances in social-evaluative settings (i.e., self-handicapping strategies). Specifically, we predicted that trait-socially anxious or shy persons would report more symptoms of social anxiety in an evaluative setting in which anxiety or shyness could serve as an excuse for poor performance than would individuals in (a) an evaluative setting in which shyness was precluded as an excuse or (b) a nonevaluative setting. Furthermore, we predicted that this self-protective pattern of symptom reporting would not occur for individuals who were not trait-socially anxious because these persons would not commonly use such symptoms as a self-handicapping strategy. Results supported these predictions for male subjects, but not for female subjects. Sex differences in the strategic use of shyness are discussed in relation to other research on sex differences in the etiology and correlates of social anxiety.

In this study, we investigated the inhibitory effect of this ointment on the formation of comedones induced by application of 50% oleic acid on the orifices of the external auditory canals of rabbits.Methods: The application sites were observed with a dermatoscope, and the area of the hair pores was measured using an Image analysis software program.Results: The chlorhexidine gluconate ointment inhibited comedone formation significantly more effectively than the liquid paraffin used as a control (P < 0.001. We also investigated the therapeutic effect of this ointment on comedones. After starting application of chlorhexidine gluconate ointment or liquid paraffin on the comedone area, the hair pore size was gradually decreased in the group treated with chlorhexidine gluconate ointment compared with the hair pore size at baseline.Conclusion: These results suggest that chlorhexidine gluconate ointment is effective for inhibiting comedone formation as well as for treating already formed comedones. Chlorhexidine gluconate ointment is a useful topical medicine for the treatment of early-stage acne and for preventing acne.Keywords: chlorhexidine gluconate ointment, comedones, dermatoscope, oleic acid

Herpes zoster (HZ; shingles) is a common viral disease that affects the nerves and surrounding skin causing a painful dermatomal rash and leading to debilitating complications such as, mainly, post-herpetic neuralgia (PHN). Currently, there is no effective treatment for HZ and PHN. The objective of this study was to assess the cost-effectiveness of a HZ vaccination program in Germany. An existing Markov Model was adapted to the German healthcare setting to compare a vaccination policy to no vaccination on a lifetime time-horizon, considering 2 scenarios: vaccinating people starting at the age of 50 or at the age of 60 years, from the perspective of the statutory health insurance (SHI) and the societal perspective. According to the perspective, vaccinating 20% of the 60+ German population resulted in 162,713 to 186,732 HZ and 31,657 to 35,793 PHN cases avoided. Corresponding incremental cost-effectiveness ratios (ICER) were 39,306 €/QALY from the SHI perspective and 37,417 €/QALY from a societal perspective. Results for the 50+ German population ranged from 336,468 to 394,575 HZ and from 48,637 to 56,087 PHN cases avoided from the societal perspective. Corresponding ICER were 39,782 €/QALY from a SHI perspective and 32,848 €/QALY from a societal perspective. Sensitivity analyses showed that results are mainly impacted by discount rates, utility values and use of alternative epidemiological data.The model indicated that a HZ vaccination policy in Germany leads to significant public health benefits and could be a cost-effective intervention. The results were robust and consistent with local and international existing literature.

For promoting the introduction of new energy and for enhancing people's consciousness of such at Murakami City, Niigata Prefecture, surveys and studies were conducted involving energy consumption in the town, the amount of new energy resources in existence, and new energy introduction projects, and a vision was formulated. The annual energy consumption of the city is estimated at 78,000 kL in terms of oil. The residential/commercial sector consumes 24,000 kL, the industrial sector 28,000 kL, and the transportation sector 26,000 kL, with the three sectors demanding similar amounts. The carbon dioxide emitted by the sectors is estimated at 223,000 t-CO2/year. New energy introduction projects were discussed, which included hot water supply, heating, road heating, and power generation, all these utilizing heat from the Senami hot spa; biogas fueled power generation and BDF (bio-diesel) bus operation in the Senami hot spa district; the introduction of a hybrid wind power/photovoltaic power generation system into Ogata Seaside Park; the introduction of a mini-scale hydroelectric power generation system into the Kamikaifu district; a large-scale wind power generation business at the Iwafune district; the introduction of wind power and photovoltaic power generation facilities into primary and junior high schools; the use of clean energy vehicles for official use; and so forth.

A detector downstream of the target will allow to search long-lived exotic particles with masses below O(10) GeV/c2 forseen in extension of the Standard Model. Another dedicated detector, that will be the focus of this talk, will allow to study active neutrino cross- sections and angular distributions. The neutrino detector consists of an emulsion target, based on the Emulsion Cloud Chamber technology fruitfully employed in the OPERA experiment. The Emulsion Cloud Chamber will be placed in a magnetic field, with the so-called Compact Emulsion spectrometer, a few cm thick chamber for the charge and momentum measurement of hadrons. This will provide the leptonic number measurement also in the hadronic tau decay channels. The detector will be hybrid, using nuclear emulsions and electr...

Search for Hidden Particles (SHiP): a new experiment proposal

Science.gov (United States)

De Lellis, G.

2015-06-01

Searches for new physics with accelerators are being performed at the LHC, looking for high massive particles coupled to matter with ordinary strength. We propose a new experimental facility meant to search for very weakly coupled particles in the few GeV mass domain. The existence of such particles, foreseen in different theoretical models beyond the Standard Model, is largely unexplored from the experimental point of view. A beam dump facility, built at CERN in the north area, using 400 GeV protons is a copious factory of charmed hadrons and could be used to probe the existence of such particles. The beam dump is also an ideal source of tau neutrinos, the less known particle in the Standard Model. In particular, tau anti-neutrinos have not been observed so far. We therefore propose an experiment to search for hidden particles and study tau neutrino physics at the same time.

The accession was preceded by a long period of political action and negotiations between the Polish and the EU institutions. The process of integration was extremely complex. It covered almost all areas of economic, legal and civil aspects of the aspiring country’s economy, in which all necessary requirements had to be met. The aim of the article was to present the institutional framework created for efficient implementation of the process of accession. The considerations involved especially an institutional method. The research resulted in poining out both the actually efficient and less efficient bodies participating in the process of integration.

Once hurt, twice shy: Social pain contributes to social anxiety.

Science.gov (United States)

Fung, Klint; Alden, Lynn E

2017-03-01

Social rejection has been consistently linked to the development of social anxiety. However, mechanisms underlying the relation have been largely unexplored, which presents an obstacle to fully understanding the origins of social anxiety and to the development of effective prevention and treatment strategies. Two studies were conducted to test the hypothesis that the emotion of social pain following rejection promotes the development of social anxiety in subsequent situations. In Study 1, undergraduate participants were exposed to 2 social situations (Cyberball) 2 days apart. Participants who were rejected in the first situation reported higher social anxiety before and during the second situation relative to those who were included. This effect was fully mediated by initial social pain intensity. In Study 2, all participants were initially rejected. Using double-blinded drug administration, participants were randomly assigned to ingest acetaminophen to alleviate the social pain from rejection, or a sugar placebo. As predicted, the acetaminophen group reported lower social anxiety before and during the second situation. Approximately half of the effect was mediated by reduction in social pain. Notably, the immediate effect of acetaminophen was specific to social pain rather than social anxiety. Results were discussed in the context of literature on the etiology of social anxiety and social pain. Future directions were suggested. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The investigation of radiation damage in Si microelectronic circuitry and devices are being carried out by various research groups globally. In particular the Si Bipolar junction transistors are very sensitive to high energetic radiation. In the present study, radiation response of NPN Bipolar junction transistor (2N3773) has been examined for 60 MeV B{sup 4+} ion. Key electrical properties like Gummel, dc current gain and capacitance – voltage (C-V) characteristics of 60 MeV B{sup 4+} ion irradiated transistor were studied before and after irradiation. Ion irradiation and subsequent electrical characterizations were performed at room temperature. Current voltage (I-V) measurements showed the increase in collector current for V{sub BE} ≤ 0.4 V as a function of fluence, which is due to B{sup 4+} ion induced surface leakage currents. Base current is observed to be more sensitive than collector current and gain appears to be degraded with ion fluence. Also, C-V measurements shows that both built in potential and doping concentration increased significantly after irradiation.

The studies of magnetocaloric properties, phase transitions, and phenomena related to magnetic heterogeneity in the vicinity of the martensitic transition (MT) in Ni-Mn-In and Ni-Mn-Ga off-stoichiometric Heusler alloys are summarized. The crystal structure, magnetocaloric effect (MCE), and magnetotransport properties were studied for the following alloys: Ni{sub 50}Mn{sub 50-x}In{sub x}, Ni{sub 50-x}Co{sub x}Mn{sub 35}In{sub 15}, Ni{sub 50}Mn{sub 35-x}Co{sub x}In{sub 15}, Ni{sub 50}Mn{sub 35}In{sub 14}Z (Z=Al, Ge), Ni{sub 50}Mn{sub 35}In{sub 15-x}Si{sub x}, Ni{sub 50-x}Co{sub x}Mn{sub 25+y}Ga{sub 25-y}, and Ni{sub 50-x}Co{sub x}Mn{sub 32-y}FeyGa{sub 18}. It was found that the magnetic entropy change, {Delta}S, associated with the inverse MCE in the vicinity of the temperature of the magneto-structural transition, TM, persists in a range of (125-5) J/(kg K) for a magnetic field change {Delta}H=5 T. The corresponding temperature varies with composition from 143 to 400 K. The MT in Ni{sub 50}Mn{sub 50-x}In{sub x} (x=13.5) results in a transition between two paramagnetic states. Associated with the paramagnetic austenite-paramagnetic martensite transition {Delta}S=24 J/(kg K) was detected for {Delta}H=5 T at T=350 K. The variation in composition of Ni{sub 2}MnGa can drastically change the magnetic state of the martensitic phase below and in the vicinity of TM. The presence of the martensitic phase with magnetic moment much smaller than that in the austenitic phase above TM leads to the large inverse MCE in the Ni{sub 42}Co{sub 8}Mn{sub 32-y}FeyGa{sub 18} system. The adiabatic change of temperature ({Delta}T{sub ad}) in the vicinity of TC and TM of Ni{sub 50}Mn{sub 35}In{sub 15} and Ni{sub 50}Mn{sub 35}In{sub 14}Z (Z=Al, Ge) was found to be {Delta}T{sub ad}=-2 K and 2 K for {Delta}H=1.8 T, respectively. It was observed that |{Delta}T{sub ad}| Almost-Equal-To 1 K for {Delta}H=1 T for both types of transitions. The results on resistivity, magnetoresistance, Hall

Self-organised nano-structuring of thin oxide-films under swift heavy ion bombardment

International Nuclear Information System (INIS)

Bolse, Wolfgang

2006-01-01

Surface instabilities and the resulting self-organisation processes play an important role in nano-technology since they allow for large-array nano-structuring. We have recently found that the occurrence of such instabilities in thin film systems can be triggered by energetic ion bombardment and the subsequent self-assembly of the surface can be nicely controlled by fine-tuning of the irradiation conditions. The role of the ion in such processes is of double nature: If the instability is latently present already in the virgin sample, but self-assembly cannot take place because of kinetic barriers, the ion impact may just supply the necessary atomic mobility. On the other hand, the surface may become instable due to the ion beam induced material modifications and further irradiation then results in its reorganisation. In the present paper, we will review recently observed nano-scale self-organisation processes in thin oxide-films induced by the irradiation with swift heavy ions (SHI) at some MeV/amu energies. The first example is about SHI induced dewetting, which is driven by capillary forces already present in the as-deposited samples. The achieved dewetting pattern show an amazing similarity to those observed for liquid polymer films on Si, although in the present case the samples were kept at 80 K and hence have never reached their melting point. The second example is about self-organised lamellae formation driven by planar stresses, which are induced by SHI bombardment under grazing incidence and result in a surface instability and anisotropic plastic deformation (hammering effect). Taking advantage of these effects and modifying the irradiation procedure, we were able to generate more complex structures like NiO-'nano-towers' of 2 μm height and 200 nm in diameter

Varying plant density and harvest time to optimize cowpea leaf yield and nutrient content

Ohler, T. A.; Nielsen, S. S.; Mitchell, C. A.

1996-01-01

Plant density and harvest time were manipulated to optimize vegetative (foliar) productivity of cowpea [Vigna unguiculata (L.) Walp.] canopies for future dietary use in controlled ecological life-support systems as vegetables or salad greens. Productivity was measured as total shoot and edible dry weights (DW), edible yield rate [(EYR) grams DW per square meter per day], shoot harvest index [(SHI) grams DW per edible gram DW total shoot], and yield-efficiency rate [(YER) grams DW edible per square meter per day per grams DW nonedible]. Cowpeas were grown in a greenhouse for leaf-only harvest at 14, 28, 42, 56, 84, or 99 plants/m2 and were harvested 20, 30, 40, or 50 days after planting (DAP). Shoot and edible dry weights increased as plant density and time to harvest increased. A maximum of 1189 g shoot DW/m2 and 594 g edible DW/m2 were achieved at an estimated plant density of 85 plants/m2 and harvest 50 DAP. EYR also increased as plant density and time to harvest increased. An EYR of 11 g m-2 day-1 was predicted to occur at 86 plants/m2 and harvest 50 DAP. SHI and YER were not affected by plant density. However, the highest values of SHI (64%) and YER (1.3 g m-2 day-1 g-1) were attained when cowpeas were harvested 20 DAP. The average fat and ash contents [dry-weight basis (dwb)] of harvested leaves remained constant regardless of harvest time. Average protein content increased from 25% DW at 30 DAP to 45% DW at 50 DAP. Carbohydrate content declined from 50% DW at 30 DAP to 45% DW at 50 DAP. Total dietary fiber content (dwb) of the leaves increased from 19% to 26% as time to harvest increased from 20 to 50 days.

Growth of health maintenance organisations in Nigeria and the potential for a role in promoting universal coverage efforts.

Science.gov (United States)

Onoka, Chima A; Hanson, Kara; Mills, Anne

2016-08-01

There has been growing interest in the potential for private health insurance (PHI) and private organisations to contribute to universal health coverage (UHC). Yet evidence from low and middle income countries remains very thin. This paper examines the evolution of health maintenance organisations (HMOs) in Nigeria, the nature of the PHI plans and social health insurance (SHI) programmes and their performance, and the implications of their business practices for providing PHI and UHC-related SHI programmes. An embedded case study design was used with multiple subunits of analysis (individual HMOs and the HMO industry) and mixed (qualitative and quantitative) methods, and the study was guided by the structure-conduct-performance paradigm that has its roots in the neo-classical theory of the firm. Quantitative data collection and 35 in-depth interviews were carried out between October 2012 to July 2013. Although HMOs first emerged in Nigeria to supply PHI, their expansion was driven by their role as purchasers in the government's national health insurance scheme that finances SHI programmes, and facilitated by a weak accreditation system. HMOs' characteristics distinguish the market they operate in as monopolistically competitive, and HMOs as multiproduct firms operating multiple risk pools through parallel administrative systems. The considerable product differentiation and consequent risk selection by private insurers promote inefficiencies. Where HMOs and similar private organisations play roles in health financing systems, effective regulatory institutions and mandates must be established to guide their behaviours towards attainment of public health goals and to identify and control undesirable business practices. Lessons are drawn for policy makers and programme implementers especially in those low and middle-income countries considering the use of private organisations in their health financing systems.

The event-by-event Monte Carlo code, TREKIS, was recently developed to describe excitation of the electron subsystems of solids in the nanometric vicinity of a trajectory of a nonrelativistic swift heavy ion (SHI) decelerated in the electronic stopping regime. The complex dielectric function (CDF) formalism was applied in the used cross sections to account for collective response of a matter to excitation. Using this model we investigate effects of the basic assumptions on the modeled kinetics of the electronic subsystem which ultimately determine parameters of an excited material in an SHI track. In particular, (a) effects of different momentum dependencies of the CDF on scattering of projectiles on the electron subsystem are investigated. The ‘effective one-band’ approximation for target electrons produces good coincidence of the calculated electron mean free paths with those obtained in experiments in metals. (b) Effects of collective response of a lattice appeared to dominate in randomization of electron motion. We study how sensitive these effects are to the target temperature. We also compare results of applications of different model forms of (quasi-) elastic cross sections in simulations of the ion track kinetics, e.g. those calculated taking into account optical phonons in the CDF form vs. Mott’s atomic cross sections. (c) It is demonstrated that the kinetics of valence holes significantly affects redistribution of the excess electronic energy in the vicinity of an SHI trajectory as well as its conversion into lattice excitation in dielectrics and semiconductors. (d) It is also shown that induced transport of photons originated from radiative decay of core holes brings the excess energy faster and farther away from the track core, however, the amount of this energy is relatively small.

Knowledge and understanding of health insurance: challenges and remedies.

Science.gov (United States)

Barnes, Andrew J; Hanoch, Yaniv

2017-07-13

As coverage is expanded in health systems that rely on consumers to choose health insurance plans that best meet their needs, interest in whether consumers possess sufficient understanding of health insurance to make good coverage decisions is growing. The recent IJHPR article by Green and colleagues-examining understanding of supplementary health insurance (SHI) among Israeli consumers-provides an important and timely answer to the above question. Indeed, their study addresses similar problems to the ones identified in the US health care market, with two notable findings. First, they show that overall-regardless of demographic variables-there are low levels of knowledge about SHI, which the literature has come to refer to more broadly as "health insurance literacy." Second, they find a significant disparity in health insurance literacy between different SES groups, where Jews were significantly more knowledgeable about SHI compared to their Arab counterparts.The authors' findings are consistent with a growing body of literature from the U.S. and elsewhere, including our own, presenting evidence that consumers struggle with understanding and using health insurance. Studies in the U.S. have also found that difficulties are generally more acute for populations considered the most vulnerable and consequently most in need of adequate and affordable health insurance coverage.The authors' findings call attention to the need to tailor communication strategies aimed at mitigating health insurance literacy and, ultimately, access and outcomes disparities among vulnerable populations in Israel and elsewhere. It also raises the importance of creating insurance choice environments in health systems relying on consumers to make coverage decisions that facilitate the decision process by using "choice architecture" to, among other things, simplify plan information and highlight meaningful differences between coverage options.

Spine surgery in Nepal: the 2015 earthquake.

Science.gov (United States)

Sutterlin, Chester E

2015-12-01

At noon on Saturday, 25 April 2015, a 7.8 magnitude earthquake struck Nepal. It was centered in the Himalaya northwest of Kathmandu, the capital of over 1 million people. The violent tremors were felt as far away as New Delhi, India 1,000 km from the epicenter, but the worst of its destructive force was experienced in the heavily populated Kathmandu valley and in the remote mountainous villages of the Himalaya. Ancient temples crumbled; poorly constructed buildings collapsed; men, women, and children were trapped and injured, sometimes fatally. Avalanches killed mountain climbers, Sherpa guides, and porters at Everest base camp (EBC). The death toll to date exceeds 8,600 with as many as 20,000 injured. Spinal Health International (SHI), a nonprofit volunteer organization, has been active in Nepal in past years and responded to requests by Nepali spine surgeons for assistance with traumatic spine injury victims following the earthquake. SHI volunteers were present during the 2(nd) major earthquake of magnitude 7.3 on 12 May 2015. Past and current experiences in Nepal will be presented.

Snapshot imaging Fraunhofer line discriminator for detection of plant fluorescence

Science.gov (United States)

Gupta Roy, S.; Kudenov, M. W.

2015-05-01

Non-invasive quantification of plant health is traditionally accomplished using reflectance based metrics, such as the normalized difference vegetative index (NDVI). However, measuring plant fluorescence (both active and passive) to determine photochemistry of plants has gained importance. Due to better cost efficiency, lower power requirements, and simpler scanning synchronization, detecting passive fluorescence is preferred over active fluorescence. In this paper, we propose a high speed imaging approach for measuring passive plant fluorescence, within the hydrogen alpha Fraunhofer line at ~656 nm, using a Snapshot Imaging Fraunhofer Line Discriminator (SIFOLD). For the first time, the advantage of snapshot imaging for high throughput Fraunhofer Line Discrimination (FLD) is cultivated by our system, which is based on a multiple-image Fourier transform spectrometer and a spatial heterodyne interferometer (SHI). The SHI is a Sagnac interferometer, which is dispersion compensated using blazed diffraction gratings. We present data and techniques for calibrating the SIFOLD to any particular wavelength. This technique can be applied to quantify plant fluorescence at low cost and reduced complexity of data collection.

Titanium substrate was coated with hydroxyapatite by radiofrequency magnetron sputtering (rf-magnetron sputtering) technique and subjected to swift heavy ion (SHI) irradiation of 125 MeV with Si 9+ at fluences of 1 × 10 10, 1 × 10 11 and 1 × 10 12 ions/cm 2. The glancing incidence X-ray diffraction (GIXRD) analysis confirmed the HAp phase of the irradiated film. There was a considerable decrease in crystallinity and particle size after irradiation. In addition, DRS-UV reflectance spectra revealed a decrease in optical band gap ( Eg) from 5.2 to 4.6 eV. Wettability of biocompatible materials plays an important role in biological cells proliferation for tissue engineering, drug delivery, gene transfer and bone growth. HAp thin films irradiated with 1 × 10 11 ions/cm 2 fluence showed significant increase in wettability. While the SHI irradiated samples exhibited enhanced bioactivity, there was no significant variation in cell viability. Surface roughness, pores and average particle size were analyzed by atomic force microscopy (AFM).

Zhu, Xiaobo; Lin, Tongen; Manning, Eric; Zhang, Yuancheng; Yu, Mengmeng; Zuo, Bin; Wang, Lianzhou

2018-06-01

The ever-growing market of electrochemical energy storage impels the advances on cost-effective and environmentally friendly battery chemistries. Lithium-ion batteries (LIBs) are currently the most critical energy storage devices for a variety of applications, while sodium-ion batteries (SIBs) are expected to complement LIBs in large-scale applications. In respect to their constituent components, the cathode part is the most significant sector regarding weight fraction and cost. Therefore, the development of cathode materials based on Earth's abundant elements (Fe and Mn) largely determines the prospects of the batteries. Herein, we offer a comprehensive review of the up-to-date advances on Fe- and Mn-based cathode materials for LIBs and SIBs, highlighting some promising candidates, such as Li- and Mn-rich layered oxides, LiNi0.5Mn1.5O4, LiFe1-xMnxPO4, NaxFeyMn1-yO2, Na4MnFe2(PO4)(P2O7), and Prussian blue analogs. Also, challenges and prospects are discussed to direct the possible development of cost-effective and high-performance cathode materials for future rechargeable batteries.

Ultrafine and highly disordered Ni 2 Fe 1 nanofoams enabled highly efficient oxygen evolution reaction in alkaline electrolyte

Nickel iron hydroxides are the most promising non-noble electrocatalysts for oxygen evolution reaction (OER) in alkaline media. By in situ reduction of metal precursors, compositionally controlled three-dimensional (3D) NixFeyB nanofoams (NFs) are synthesized with high surface area and uniformly distributed bimetallic networks. The resultant ultrafine amorphous Ni2Fe1B NFs exhibit extraordinary electrocatalytic performance toward OER and overall water splitting in alkaline media. At a potential as low as 1.42 V (vs. RHE), Ni2Fe1B NFs can deliver a current density of 10 mA/cm2 and show negligible activity loss after 12 hours’ stability test. Even at large current flux of 100 mA/cm2, an ultralow overpotential of 0.27 V is achieved, which is about 0.18 V more negative than benchmark RuO2. Both ex-situ Mӧssbauer spectroscopy and X-ray Absorption Spectroscopy (XAS) reveal a phase separation and transformation for the Ni2Fe1B catalyst during OER process. The evolution of oxidation state and disordered structure of Ni2Fe1B might be a key to the high catalytic performance for OER.

Nucleation mechanisms in high energy ion beam induced dewetting

Energy Technology Data Exchange (ETDEWEB)

Haag, Michael; Garmatter, Daniel; Ferhati, Redi; Amirthapandian, Sankarakumar; Bolse, Wolfgang [Institut fuer Halbleiteroptik und Funktionelle Grenzflaechen, Universitaet Stuttgart (Germany)

2011-07-01

Solid coatings, when heated above their melting points, often break up by forming small round holes, which then grow, coalesce and finally turn the initially contiguous film into a pattern of isolated droplets. Such dewetting has been intensively studied using thin polymer films on Si. Three different hole nucleation mechanisms were discovered: homogeneous (spontaneous) nucleation, heterogeneous nucleation at defects, and spinodal dewetting by self-amplifying capillary waves. We have recently found that swift heavy ion (SHI) irradiation of thin oxide films on Si results in similar dewetting patterns, even though the films were kept far below their melting points. Using our new in-situ SEM at the UNILAC accelerator of GSI, we were now able to identify the mechanisms behind this SHI induced dewetting phenomenon. By varying the film thickness and introducing defects at the interface, we can directly address the hole nucleation processes. Besides homogeneous and heterogeneous nucleation, we also found a process, which very much resembles the spinodal mechanism found for liquid polymers, although in the present case the instable wavy surface is not generated by capillary waves, but by ion beam induced stresses.

Saturation of plastic deformation by swift heavy ion irradiation: Ion hammering vs. surface effects

Energy Technology Data Exchange (ETDEWEB)

Ferhati, Redi; Dautel, Knut; Bolse, Wolfgang [Institut fuer Halbleiteroptik und Funktionelle Grenzflaechen, Universitaet Stuttgart (Germany); Fritzsche, Monika [Helmholtz-Zentrum Dresden-Rossendorf (Germany)

Swift heavy ion (SHI) induced plastic deformation is a subject of current research and scientific discussion. This *Ion Hammering* phenomenon was first observed 30 years ago in amorphous materials like metallic glasses. About 10 years ago, Feyh et al. have shown that stress generation and *Ion Hammering* result in self-organization of thin NiO-films on Si-wafers into a sub-micron lamellae-like structure under grazing angle irradiation. The growth of the lamellae was found to saturate as soon as they have reached a thickness of a few hundreds of nm. Here we show our latest results on the restructuring of pre-patterned thin oxide films by SHI under various irradiation conditions. The experiments were performed by employing (in-situ) scanning electron microscopy, and were complemented by (in-situ) energy dispersive x-ray analysis and atomic force microscopy. As we will show, the saturation behavior can be understood as a competition of *Ion Hammering* and surface energy effects, while the unexpected fact, that the initially crystalline films undergo *Ion Hammering* can possibly be attributed to oxygen loss and thus amorphization during irradiation.

Alternative approaches to electronic damage by ion-beam irradiation: Exciton models

The paper briefly describes the main features of the damage produced by swift heavy ion (SHI) irradiation. After a short revision of the widely used thermal spike concept, it focuses on cumulative mechanisms of track formation which are alternative to those based on lattice melting (thermal spike models). These cumulative mechanisms rely on the production of point defects around the ion trajectory, and their accumulation up to a final lattice collapse or amorphization. As to the formation of point defects, the paper considers those mechanisms relying on direct local conversion of the excitation energy into atomic displacements (exciton models). A particular attention is given to processes based on the non-radiative recombination of excitons that have become self-trapped as a consequence of a strong electron-phonon interaction (STEs). These mechanisms, although operative under purely ionizing radiation in some dielectric materials, have been rarely invoked, so far, to discuss SHI damage. They are discussed in this paper together with relevant examples to materials such as Cu{sub 3}N, alkali halides, SiO{sub 2}, and LiNbO{sub 3}. (copyright 2016 WILEY-VCH Verlag GmbH and Co.

Effect of type of schooling and gender on sociability and shyness among students

Directory of Open Access Journals (Sweden)

Archana Singh

2017-01-01

Full Text Available Background: Sociability and shyness are orthogonal personality traits, wherein both are characterized by varying behavioral and psychophysiological correlates. Shyness should not be equated with the lack of sociability, as shyness relates to discomfort that occurs in the presence of others and sociability is identified with an individual's preference for being with others rather than alone. Objectives: The objective of this study was to examine the effect of type of schooling on sociability and shyness among students and to study the gender differences between sociability and shyness among students. Methodology: The sample comprised 210 students from both private and government schools situated in Delhi. Data were collected using Eysenck Personality Profiler for measuring sociability and Revised Cheek and Buss Shyness Scale. Results and Conclusion: The results obtained from ANOVA revealed that government school students were observed to be more sociable as compared to private school students. On the other hand, private school students were found to be more shy as compared to government school students. Females were observed to be more shy as compared to males. In addition, significant interactive effect was observed for sociability when school and gender were taken altogether.

2016-01-01

SHIP is a new general purpose fixed target facility, proposed at the CERN SPS accelerator. In five years, $2\\times 10^{20}$ protons of 400 GeV/c momentum will be dumped on a Molybdenum target. A detector downstream of the target will allow a search to made for long-lived particles with masses below O(10) GeV/c$^2$ foreseen in several extensions of the Standard Model. Another dedicated detector will allow the study of active neutrino cross-sections and angular distributions. The neutrino detector consists of an emulsion target, based on the Emulsion Cloud Chamber technology fruitfully employed in the OPERA experiment. The Emulsion Cloud Chamber will be placed in a magnetic field, with the so-called Compact Emulsion Spectrometer, a few cm thick chamber for the charge and momentum measurement of hadrons. This will provide the leptonic number measurement also in the hadronic tau decay channels. The detector will be hybrid, using nuclear emulsions and electronic detectors for the time stamp of the events and the m...

An inhomogeneous T-Q equation for the open XXX chain with general boundary terms: completeness and arbitrary spin

2013-01-01

An inhomogeneous T-Q equation has recently been proposed by Cao, Yang, Shi and Wang for the open spin-1/2 XXX chain with general (nondiagonal) boundary terms. We argue that a simplified version of this equation describes all the eigenvalues of the transfer matrix of this model. We also propose a generating function for the inhomogeneous T-Q equations of arbitrary spin. (fast track communication)

HADIS DI KALANGAN SUNNI (SHAHIH BUKHORI DAN SYI’AH (AL-KAFI Al- KULAINI

Full Text Available Sunnah or hadith has a unique and long history. He had experienced the transition from oral tradition to written tradition. The compilation also requires a fairly long time. Political competition among Muslims groups is also coloring in the context of the power struggle. Until the end of the 9th century, the codification effort can produce some great collections (hadith which is considered to be authentic, in addition to a large number of other hadith collections. There is an assumption, that the belief differences in Islam streams impacted or even become the source of hadith differences that recognized by each group. For example Sunni groups just hold on a history of Sunni only, while Shi’ites only recognize the traditions of the history of Shi'ite only and so on. Study hadith among Sunni use the book of Saheeh Bukhari by Imam Bukhari and among Shi'ites use the book of al-kafi by al Kulaini, because both of books are famous books in the both of groups. Comparison of the two hadiths in both of them is assessed through: (1 systematic of the book contents; (2 method of the book preparation; (3 characteristics and features of the books; (4 quality of the book; (5 authentic level of the book; (6 criticisms and comments of the scholars. The results study showed that Al Kafi in the Shi’ite side is unequal footing with Sahih Bukhari on the Sunni side. Al Kafi has become a reference by Shi'ite cleric but no Shia scholar can prove that all of Al-Kafi history is Saheeh. In taking hadith as a reference, the Shia scholars would assess the position of hadith then set the fatwa. This is clearly different with Shahih Bukhari where Bukhari himself said that all of the hadiths are authentic, and has become the consensus of scholars (Sunni that Sahih Bukhari is the most authentic book after the Qur'an.

This study was conducted to investigate the effects of post-harvest storage duration and wheat variety on the digestibility and energy content of new season wheat fed to finishing pigs. Two wheat varieties (Shi and Zhong) were harvested in 2013 and stored in the warehouse of the Fengning Pig Experimental Base at China Agricultural University for 3, 6, 9, or 12 mo. For each storage period, 12 barrows were placed in metabolism crates and allotted to diets containing 1 of the 2 wheat varieties in a randomized complete block design. The experimental diets contained 97.34% wheat and 2.66% of a vitamin and trace mineral premix. With an extension of storage duration from 3 mo to 12 mo, the gross energy (GE) and crude protein (CP) of the wheat decreased by 2.0% and 12.01%, respectively, while the concentration of neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch content increased by 30.26%, 19.08%, and 2.46%, respectively. Total non-starch polysaccharide, total arabinose, total xylose and total mannose contents decreased by 46.27%, 45.80%, 41.71%, and 75.66%, respectively. However, there were no significant differences in the chemical composition between the two wheat varieties with the exception of ADF which was approximately 13.37% lower in Shi. With an extension of storage duration from 3 mo to 12 mo, the digestible energy (DE), metabolizable energy (ME) content and the apparent total tract digestibility of GE, CP, dry matter, organic matter, ether extract, ADF and metabolizability of energy in wheat decreased linearly (pdigestibility of NDF changed quadratically (pdigestibility (pdigestibility of variety Zhong was stable during 9 mo of storage, while the CP digestibility of variety Shi decreased (p<0.05). In conclusion, the GE, DE, and ME of wheat was stable during the first 3 to 6 mo of post-harvest storage, and decreased during the following 6 to 12 mo of storage under the conditions of this study.

2008-01-01

The present study compares structural and optical modifications of bare and silica (SiO 2 ) coated ZnS quantum dots under swift heavy ion (SHI) irradiation. Bare and silica coated ZnS quantum dots were prepared following an inexpensive chemical route using polyvinyl alcohol (PVA) as the dielectric host matrix. X-ray diffraction (XRD) and transmission electron microscopy (TEM) study of the samples show the formation of almost spherical ZnS quantum dots. The UV-Vis absorption spectra reveal blue shift relative to bulk material in absorption energy while photoluminescence (PL) spectra suggests that surface state and near band edge emissions are dominating in case of bare and coated samples, respectively. Swift heavy ion irradiation of the samples was carried out with 160 MeV Ni 12+ ion beam with fluences 10 12 to 10 13 ions/cm 2 . Size enhancement of bare quantum dots after irradiation has been indicated in XRD and TEM analysis of the samples which has also been supported by optical absorption spectra. However similar investigations on irradiated coated quantum dots revealed little change in quantum dot size and emission. The present study thus shows that the coated ZnS quantum dots are stable upon SHI irradiation compared to the bare one

Personality and the collective: bold homing pigeons occupy higher leadership ranks in flocks.

2018-05-19

While collective movement is ecologically widespread and conveys numerous benefits on individuals, it also poses a coordination problem: who controls the group's movements? The role that animal 'personalities' play in this question has recently become a focus of research interest. Although many animal groups have distributed leadership (i.e. multiple individuals influence collective decisions), studies linking personality and leadership have focused predominantly on the group's single most influential individual. In this study, we investigate the relationship between personality and the influence of multiple leaders on collective movement using homing pigeons, Columba livia , a species known to display complex multilevel leadership hierarchies during flock flights. Our results show that more exploratory (i.e. 'bold') birds are more likely to occupy higher ranks in the leadership hierarchy and thus have more influence on the direction of collective movement than less exploratory (i.e. 'shy') birds during both free flights around their lofts and homing flights from a distant site. Our data also show that bold pigeons fly faster than shy birds during solo flights. We discuss our results in light of theories about the evolution of personality, with specific reference to the adaptive value of heterogeneity in animal groups.This article is part of the theme issue 'Collective movement ecology'. © 2018 The Author(s).

The current study compared the predicted social and career impact of socially withdrawn and reticent behaviors among participants from Western and East Asian countries. Three hundred sixty-one college students from 5 Western countries and 455 students from 3 East Asian countries read hypothetical vignettes describing socially withdrawn and shy behaviors versus socially outgoing and confident behaviors. Participants then answered questions following each vignette indicating the extent to which they would expect the subject of the vignette to be socially liked and to succeed in their career. Participants also completed measures of their own social anxiety and quality of life. The results indicated significant vignette-by-country interactions in that the difference in perceived social and career impact between shy and outgoing vignettes was smaller among participants from East Asian countries than from Western countries. In addition, significant negative correlations were shown between personal level of shyness and experienced quality of life for participants from both groups of countries, but the size of this relationship was greater for participants from Western than East Asian countries. The results point to the more negative impact of withdrawn and socially reticent behaviors for people from Western countries relative to those from East Asia. Copyright © 2011.

Byrd, Courtney T; McGill, Megann; Gkalitsiou, Zoi; Cappellini, Colleen

2017-02-01

The purpose of this study was to examine the influence of self-disclosure on observers' perceptions of persons who stutter. Participants (N = 173) were randomly assigned to view 2 of 4 possible videos (i.e., male self-disclosure, male no self-disclosure, female self-disclosure, and female no self-disclosure). After viewing both videos, participants completed a survey assessing their perceptions of the speakers. Controlling for observer and speaker gender, listeners were more likely to select speakers who self-disclosed their stuttering as more friendly, outgoing, and confident compared with speakers who did not self-disclose. Observers were more likely to select speakers who did not self-disclose as unfriendly and shy compared with speakers who used a self-disclosure statement. Controlling for self-disclosure and observer gender, observers were less likely to choose the female speaker as friendlier, outgoing, and confident compared with the male speaker. Observers also were more likely to select the female speaker as unfriendly, shy, unintelligent, and insecure compared with the male speaker and were more likely to report that they were more distracted when viewing the videos. Results lend support to the effectiveness of self-disclosure as a technique that persons who stutter can use to positively influence the perceptions of listeners.

Electrical and optical properties of pristine and swift heavy ion (SHI) irradiated p-n junction diode have been investigated for advanced electronics application. Fe:SnO{sub 2}/Li:NiO p-n junction was fabricated by using pulsed laser deposition on c-sapphire substrate. The optical band gaps of Fe:SnO{sub 2} and Li:NiO films were obtained to be 3.88 and 3.37 eV, respectively. The current-voltage characteristics of the oxide-based p-n junction showed a rectifying behaviour with turn-on voltage of 0.95 V. The oxide-based p-n junction diode was irradiated to 80 MeV O{sup +6} ions with 1 x 10{sup 12} ions/cm{sup 2} fluence. Decrease in grain size due to SHI irradiation is confirmed by the grazing angle X-ray diffraction and atomic force microscopy. In comparison with the pristine p-n junction diode, O{sup +6} ion irradiated p-n junction diode shows the increase of surface roughness and decrease of percentage transmittance in visible region. For irradiated p-n junction diode, current-voltage curve has still rectifying behaviour but exhibits lower turn-on voltage than that of virgin p-n junction diode. (orig.)

The effect of swift heavy ions (SHI) on magnetic ordering in ZnS thin films with Co ions substituted on Zn sites is investigated. The materials have been synthesized by pulsed laser deposition on substrates held at 600 Degree-Sign C for obtaining films with wurtzite crystal structure and it showed ferromagnetic ordering up to room temperature with a paramagnetic component. 120 MeV Ag ions have been used at different fluences of 1 Multiplication-Sign 10{sup 11} ions/cm{sup 2} and 1 Multiplication-Sign 10{sup 12} ions/cm{sup 2} for SHI induced modifications. The long range correlation between paramagnetic spins on Co ions was destroyed by irradiation and the material became purely paramagnetic. The effect is ascribed to the formation of cylindrical ion tracks due to the thermal spikes resulting from electron-phonon coupling. - Highlights: Black-Right-Pointing-Pointer Effect of swift heavy ions on magnetic ordering in Co doped ZnS thin films are presented. Black-Right-Pointing-Pointer Magnetization in the pristine films is composed of ferromagnetic and paramagnetic components. Black-Right-Pointing-Pointer The films become purely paramagnetic after swift heavy ions irradiation. Black-Right-Pointing-Pointer The magnetic transition is ascribed to the formation of ion track (or cylindrical defects) due to the thermal spikes.

2008-01-01

Gadolinium-substituted yttrium iron garnets are ferrite materials of primary importance in microwave engineering. Stoichiometric powders of nominal composition Y 2.6 Gd 0.4 Fe 5 O 12 (i.e. Fe/(Y + Gd) = 1.67) were prepared by reverse strike coprecipitation of metal nitrates. In order to investigate the influence of composition on phase formation, non-stoichiometric powders were also synthesised. On the basis of DTA/TGA analysis, dried coprecipitates were calcined between 600 deg. C and 1200 deg. C and then characterised by ICP, XRD and HT-XRD. Amorphous coprecipitates crystallise around 700 deg. C in cubic garnet phase along with small amounts of YFeO 3 and/or α-Fe 2 O 3 . Only iron-rich garnets, either pure or Gd-substituted, calcined at 1200 deg. C or above display a single-phase cubic garnet. According to thermal dilatometry results, calcined powders were sintered in air up to 1470 deg. C. The microstructure of sintered ceramics is made up of fine grains, the average size ranging between 3 μm and 13 μm. Density of sintered bodies ranged from 88% to 98%. Ferromagnetic resonance linewidth (ΔH -3dB ) ranged between 4352.9 A m -1 and 4392.7 A m -1 , depending on composition and microstructure

Study of iron exchanged zeolites by Moessbauer effect and electron spin resonance spectroscopy

International Nuclear Information System (INIS)

Aguirre Campuzano, C.E.

1993-01-01

Crystalline iron exchanged NaY zeolites, prepared from aqueous solutions and calcined at atmospheric conditions, have been studied and characterized by XRD, Moessbauer and EPR spectroscopies and TGA analysis. Three iron sites are clearly distinguished from Moessbauer and EPR measurements. Firstly, characteristic Moessbauer and EPR spectra may arise from framework sites, suggesting that Fe has substituted Al. It is also found that their spectroscopic signals are not intensity affected by thermal treatments. Secondly, a Moessbauer doublet which may arise from octahedral sites in the large cavity of the zeolite, shows however, that this doublet and its EPR signal are intensity temperature affected. An additional line broadening is observed on the low velocity line of this doublet, Thirdly, characteristic Moessbauer and EPR signals, which are also intensity temperature dependent have been associated to accluded material, where the Moessbauer doublet presents the line broadening effect before mentioned. Such line broadening effect may be due to perturbing signals from iron ions in tetrahedral sites. Finally, it has been observed that during calcination of the FeY zeolites, the three characteristic EPR signals for the three iron sites, do not increase at the expenses of the other. A result that may suggest a strong bonding between Fe-site of the Y zeolite, irrespective of the iron source. (Author)
