Full Text Available Utilizaram-se sete carneiros, sem raça definida, fistulados no rúmen e duodeno, para avaliar o consumo e as digestibilidades aparentes totais e parciais de matéria seca (MS, matéria orgânica (MO, proteína bruta (PB, extrato etéreo (EE, fibra em detergente neutro (FDN, fibra em detergente ácido (FDA, celulose (CEL e hemicelulose (HCEL do feno de Stylosanthes guianensis. Os animais receberam apenas feno de S. guianensis mais sal mineral como componentes da dieta. O fornecimento do feno foi ad libitum, sendo a quantidade calculada para permitir sobras de 20%. Utilizou-se óxido crômico como indicador para estimar a produção de fezes e o fluxo de digesta no duodeno. Os consumos de MS e MO do S. guianensis foram 67,71 e 64,70 g/kg0,75, respectivamente. As digestibilidades aparentes totais da MS, MO, PB, FDN e FDA foram 49,2, 51,3, 61,2, 42,0 e 42,7%, respectivamente. As digestibilidades aparentes ruminais da MS, MO, FDN e FDA foram 75,8, 84,7, 89,6 e 90,6%, respectivamente, em função do total digerido. A digestibilidade ruminal da PB foi 21,3%. Concluiu-se que o feno de S. guianensis, colhido em estádio de maturidade avançada, pode ser indicado para ruminantes, pois seu consumo é capaz de atender às necessidades energéticas de mantença já que seus valores, apesar de sua digestibilidade não ser elevada, são ligeiramente maiores do que os de outras forrageiras tropicais.Seven rumen and duodenal cannulated lambs were used to evaluate the intake and the total and the partial apparent digestibilities of dry matter (DM, organic matter (OM, crude protein (CP, ether extract (EE, neutral detergent fiber (NDF, acid detergent fiber (ADF, cellulose (CEL and hemicellulose (HCEL of the Stylosanthes guianensis hay. The diet was composed by the hay of S. guianensis plus mineral salt. The hay was offered ad libitum with the refusals estimated for being 20%. Chromium oxide was used as an external marker, to estimate fecal production and digesta

This experiment was conducted to determine the variations in carotenoid, vitamins A and E concentrations, and color in the plasma and milk of dairy cows following a shift from a hay diet to diets containing increasing levels of carotenoids and vitamin E. This study was performed on 32 multiparous Montbéliarde dairy cows in midlactation. After a 6-wk preexperimental period on a diet based on hay and concentrates, the cows were allocated to 4 homogeneous groups, and thereafter fed for 6 wk on isoenergetic experimental diets where the hay was replaced by an experimental feed rich in carotenoids and vitamin E, consisting in 75% grass silage and 25% alfalfa protein concentrate (PX Agro Super Desialis, Châlons en Champagne, France). The hay-to-experimental feed ratios were 100/0 in group 1, 67/33 in group 2, 33/67 in group 3, and 0/100 in group 4, providing 1.6, 3.6, 5.4, and 7.4 g/d of total carotenoids, respectively. Variations in carotenoid, vitamins A and E concentrations as well as variations in color index (CI) were monitored from d -7 through to d 42 on the experimental diets. Zeaxanthin, lutein, 13-cis-beta-carotene, and all-trans-beta-carotene accounted for an average 3, 10, 9, and 78%, respectively, of total carotenoids in plasma and 0, 17, 12, and 71%, respectively, of total carotenoids in milk. The switch from preexperimental to experimental diets only slightly affected zeaxanthin, lutein, and vitamin A concentrations in plasma and milk. A rapid increase in vitamin E and beta-carotene (BC) was observed during the first week in both plasma and milk. For vitamin E, the time to reach a plateau was from 8 d (group 2) to 28 d (group 4) in plasma, and 5 d (groups 2-4) in milk. Plasma concentrations of BC had stabilized after 28 d in group 2 but were not stabilized after 42 d in groups 3 and 4, whereas milk concentrations of BC plateaued from d 21 in group 2 and d 28 in groups 3 and 4. At the end of the experimental period, BC and vitamin E concentrations in

Full Text Available Increasing the efficiency of utilization of fresh and preserved forage is a key target for ruminant science. Vitamin E is often used as additive to improve product quality but its impact of the rumen function is unknown. This study investigated the successional microbial colonization of ryegrass (GRA vs. ryegrass hay (HAY in presence of zero or 50 IU/d supplementary vitamin E, using a rumen simulation technique. A holistic approach was used to link the dynamics of feed degradation with the structure of the liquid-associated (LAB and solid-associated bacteria (SAB. Results showed that forage colonization by SAB was a tri-phasic process highly affected by the forage conservation method: Early colonization (0–2 h after feeding by rumen microbes was 2× faster for GRA than HAY diets and dominated by Lactobacillus and Prevotella which promoted increased levels of lactate (+56% and ammonia (+18%. HAY diets had lower DM degradation (-72% during this interval being Streptococcus particularly abundant. During secondary colonization (4–8 h the SAB community increased in size and decreased in diversity as the secondary colonizers took over (Pseudobutyrivibrio promoting the biggest differences in the metabolomics profile between diets. Secondary colonization was 3× slower for HAY vs. GRA diets, but this delay was compensated by a greater bacterial diversity (+197 OTUs and network complexity resulting in similar feed degradations. Tertiary colonization (>8 h consisted of a slowdown in the colonization process and simplification of the bacterial network. This slowdown was less evident for HAY diets which had higher levels of tertiary colonizers (Butyrivibrio and Ruminococcus and may explain the higher DM degradation (+52% during this interval. The LAB community was particularly active during the early fermentation of GRA and during the late fermentation for HAY diets indicating that the availability of nutrients in the liquid phase reflects the dynamics

The Conservation Reserve Program (CRP) is a voluntary program that is available to agricultural producers to help protect environmentally sensitive or highly erodible land. Management disturbances of CRP grasslands generally are not allowed unless authorized to provide relief to livestock producers during severe drought or a similar natural disaster (i.e., emergency haying and grazing) or to improve the quality and performance of the CRP cover (i.e., managed haying and grazing). Although CRP grasslands may not be hayed or grazed during the primary bird-nesting season, these disturbances may have short-term (1 yr after disturbance) and long-term (≥2 yr after disturbance) effects on grassland bird populations. We assessed the effects of haying on 20 grassland bird species in 483 CRP grasslands in 9 counties of 4 states in the northern Great Plains, USA between 1993 and 2008. We compared breeding bird densities (as determined by total-area counts) in idle and hayed fields to evaluate changes 1, 2, 3, and 4 years after haying. Haying of CRP grasslands had either positive or negative effects on grassland birds, depending on the species, the county, and the number of years after the initial disturbance. Some species (e.g., horned lark [Eremophila alpestris], bobolink [Dolichonyx oryzivorus]) responded positively after haying, and others (e.g., song sparrow [Melospiza melodia]) responded negatively. The responses of some species changed direction as the fields recovered from haying. For example, densities for common yellowthroat (Geothlypis trichas), sedge wren (Cistothorus platensis), and clay-colored sparrow (Spizella pallida) declined the first year after haying but increased in the subsequent 3 years. Ten species showed treatment × county interactions, indicating that the effects of haying varied geographically. This long-term evaluation on the effects of haying on breeding birds provides important information on the strength and direction of changes in

Since, the ablation of organic materials by photo decomposition process using UV lasers have many different applications in fields such as optoelectronics, microelectronics and surgery, therefore an special attention is given to it. The time resolved information together with available mathematical models can provide a better understanding about ablation. As the ablation of materials begin a few nanoseconds after arrival of photons, thus it would be useful if one can study the ablation process in a time scale shorter than the laser pulse duration. In this article, the possible application of PVDF piezoelectric transducer to study the photoacoustic reaction of polymers against excimer lasers is described. Time resolved signals in two areas will be useful I- The thermoelastic region below threshold which gives some information about optical characteristics of target and also thermal relaxation time of excited states, II- Ablation time scale above threshold which provide us information regarding the nature of ablation mechanism. The experiments have shown that PET and polyimide polymers began to ablate within (4-6)ns of ArF pulse width at a fluence higher than 100 mJcm{sup -2}. This produced a short acoustic pulse of 20 ns with a maximum pressureof 10{sup 7} pa (100 atm). Ablation of PMMA using the same laser began within 8 ns. These results show that the polymers with high absorption coefficients are photochemically decomposed and those with low absorption coefficients such as PET at 308 nm, the ablation is brought about by thermal effects.

Full Text Available This work had as objectives to evaluate the performance of lambs weaned at 67 days of age and fed with different roughage sources in confinement. Thirty animals out of Corriedale ewes mated to Hampshire Down, Ile de France and Suffolk rams, were used. After weaning the animals were fedlot and distributed in one of the following treatments: T1 – Corn silage + concentrate; T2 – Corn silage and oat hay (50% each + concentrate; and T3 – Oat hay + concentrate. It was used a 60:40 roughage:concentrate ratio, dry matter basis. At the beginning of the experiment the animals weighed 11.51, 12.46 and 12.33 kg (P>0.05, and after nine weeks of feedlot the weights were 17.53, 19.34 and 19.35 kg (P>0.05, respectively, for T1, T2 e T3. Average daily weight gain was similar (P>0.05 among treatments. It was not observed differences (P>0.05 in weights and weight gains among the genetic groups. However, male lambs presented greater average daily weight gain than female lambs (0.120 x 0.091 kg. There were no differences in feed conversion among the treatments, however, animals from the T2 had greater dry matter intake.

Full Text Available Cassava (Manihot esculenta Crantz, although native to Brazil, is still underutilized, especially when it comes to using its aerial part. In order to study the potential of the cassava plant for use as animal feed, the present work evaluated the characteristics of the aerial part of cassava when submitted to the processes of ensiling and haymaking. Treatments consisted of: aerial part of the plant ensiled without wilting (PAS; aerial part ensiled after wilting (PAE, and aerial part made into hay (PAF. Chemical analyses were run in order to evaluate the traits that determine the nutritional value of silage and hay. Wilting increased dry matter concentration from 25% to 27.7%, without changing the concentration of soluble carbohydrates (33.3 and 35.5% in the PAS and PAE, respectively, as well as buffer capacity (204 mmol kg-1 DM in PAS and 195 mmol kg-1 DM in PAE. Neither pH (3.57 in fresh silage and 3.60 in PAE nor the ADIN concentration (11.32% of total nitrogen in PAS and 9.99% of total nitrogen in PAE differed between the silages, but ADIN concentration was higher in hay (15.39%. Wilting caused an increase in the concentration of ammonia (from 6.5% of total nitrogen in PAS to 13.0 of total nitrogen in PAE. The levels of volatile fatty acids did not change with wilting. The ensiling process reduced the concentrations of free hydrocyanide (HCN, without, however, affecting cyanohydrin.A mandioca, apesar de ser nativa do Brasil, ainda é sub-utilizada principalmente quando a questão é o aproveitamento da sua parte aérea.

Motivation for hay: effects of a pelleted diet on behavior and physiology of horses.

Science.gov (United States)

Elia, Jamie B; Erb, Hollis N; Houpt, Katherine Albro

The natural diet of free-ranging horses is grass, which is typically high in fiber and calorically dilute, however diets for high performance domestic horses are often low in fiber and calorically dense. The aim of the study was to determine the motivation of horses for hay when fed a low roughage diet. Their motivation could be used to determine if low roughage diets compromise the welfare of horses. Eight mares were fed two different diets in counterbalanced order: ad libitum orchard grass hay; a complete pelleted feed (pellets). Each trial lasted three weeks, with a one-week transition period between diets. To determine the motivation of horses for fiber they were taught to press a panel to obtain a food reward. The fixed ratio (FR) was increased using a progressive ratio ((1,2,4,7,11…) technique. When fed pellets, the horses worked for a median FR of 1 (Range=1-497) to attain pellets, and when fed hay, they worked for a median FR of 25.5 (4-497) to attain pellets. When fed hay, the horses worked for a median FR of 0 (0-0) to attain hay, and when fed pellets, they worked for a FR of 13 (2-79) to attain hay. These results indicate a greater motivation for hay, a high fiber diet, when fed a low fiber diet. The horses spent 10 (5-19.4)% of their time during a 24-hour period eating pellets compared to 61.5 (29-76) % of their time eating hay. Horses spent 58% of their time standing when fed the pellets and only 37% of their time standing when fed hay. Searching behavior (i.e. sifting through wood shaving bedding for food particles) took up 11.5 (1.4-32) % of the horse's day when fed pellets, but only 1.2 (0-3.5) % of the daily time budget when fed hay. Horses chew more times when eating a hay diet (43,476chews/day) than when eating a pellet diet (10,036chews/day). Fecal pH was lower in horses fed the pelleted diet. Copyright © 2010 Elsevier Inc.

Signals for compositeness in e-e+→e-e+ and e-e+→μ-μ+

International Nuclear Information System (INIS)

Bars, I.; Gunion, J.F.; Kwan, M.

1986-01-01

Theories in which leptons are composite lead to additional contributions (beyond those from the standard model) to the amplitudes for e - e + →e - e + and e - e + →μ - μ + . Detailed models, constructed by analogy between QCD and compositeness/precolor interactions lead to specific forms for these extra terms. We demonstrate that compositeness scales M as high as 4--7 TeV may be probed using e - e + collision machines currently available and planned for the near future. Sensitivity to the type of composite model and its parity-violation structure is demonstrated. In particular we point out that there are no standard-model contributions to the scattering e - e + →μ - μ + when the incoming e - and e + both have the same helicity. Observation of a nonzero cross section in such a helicity scattering state is prima facie evidence of flavor-changing vector currents in the t channel or scalar currents connecting the e and μ lepton sectors in the s channel
Inclusive (e,e'N), (e,e'NN), (e,e'π),... reactions in nuclei

1997-01-01

We study the inclusive (e,e'N), (e,e'NN), (e,e'π), (e,e'πN) reactions in nuclei using a Monte Carlo simulation method to treat the multichannel problem of the final state. The input consists of reaction probabilities for the different steps evaluated using microscopical many body methods. We obtain a good agreement with experiment in some channels where there is data and make predictions for other channels which are presently under investigation in several electron laboratories. The comparison of the theoretical results with experiment for several kinematical conditions and diverse channels can serve to learn about different physical processes occurring in the reaction. The potential of this theoretical tool to make prospections for possible experiments, aiming at pinning down certain reaction probabilities, is also emphasized. (orig.)

O tratamento do substrato influencia a ação do fungo e a qualidade final do produto. Neste experimento, aplicaram-se quatro tratamentos (compostagem do feno inteiro, compostagem do feno picado, hidratação do feno em água fria e hidratação do feno em água quente a um feno de Brachiaria decumbens. Aos tratamentos seguiu-se inoculação com o fungo Pleurotus ostreatus e incubação por 35 dias, sob temperatura controlada. Usou-se o delineamento inteiramente casualizado, com quatro repetições e medidas repetidas. Amostras foram colhidas semanalmente para acompanhar a degradação do substrato, mediante a análise química do feno. Observou-se aumento linear, com o decorrer do tempo, no teor de proteína bruta (PB e na proporção de lignina na parede celular (LIG-FDN, e decréscimo linear nos valores de fibra em detergente neutro (FDN, celulose e hemicelulose. Não se observou efeito de tratamento no teor de FDA. Os tratamentos com compostagem apresentaram maiores valores de PB, lignina e LIG-FDN e menores de FDN e hemicelulose. Não se observou diferença entre os tratamentos com hidratação. O tratamento do feno de braquiária com o fungo propiciou degradação da fração fibrosa e aumento no teor de PB, com efeito mais intenso nos tratamentos que usaram compostagem.

Exposure to farming environments and siblings is associated with reduced risks of childhood hay fever and atopy. We explored the independence and interaction of these protective effects in the GABRIELA study. Questionnaire surveys on farming, asthma, and allergies were conducted in four central European areas among 79,888 6-12-yr-old children. Aeroallergen-specific serum IgE was measured in a stratified sample of 8,023 children. Multiple logistic regression was used to compare gradients in allergy prevalence by sibship size across three categories of exposure to farming environments. The prevalence of hay fever ranged from 2% (95% confidence interval 1.6%; 2.7%) among farmers' children with more than two siblings to 12% (11.2%; 13.0%) among children with no farm exposure and no siblings. Farming families were larger on average. More siblings and exposure to farming environments independently conferred protection from hay fever and atopy. There was no substantial effect modification between family size and exposure to farming environments. The odds ratios for hay fever per additional sibling were 0.79 among unexposed non-farm children, 0.77 among farm-exposed non-farm children, and 0.72 among children from farming families (2df interaction test: p = 0.41). The inverse association of exposure to farming environments with hay fever is found in all sizes of family, with no substantial tendency to saturation or synergism. This suggests that different biological mechanisms may underlie these two protective factors. Combinations of a large family and exposure to farming environments markedly reduce the prevalence of hay fever and indicate the strength of its environmental determinants. © 2013 John Wiley & Sons A/S.

After subtraction of the background from the ALEPH date the following N exp / μ +μ - μ + μ - = 4.88 ± (2.24) stat N exp / e + e - μ + μ - 24.1 (5.1) stat ± (0.16) sys and N exp / e + e - e + e - = 10.4 ± (4.1 stat) ± (0.44) sys results, while the event numbers expected according to the standard model are given by N theo / μ + μ - μ + μ - = 3.46 (0.04) stat ± (0.42) sys N theo / e + e - μ + μ - = 14.48 ± (0.19) stat ± (1.97) sys and N theo / e + e - e + e - = 12.24 ± (0.21) stat ± (1.46) sys. An X 2 test shows a confidence level of 30% for the hypothesis of the description of the data by the standard model of the electroweak interactions. Furthermore the invariant masses of the lepton pairs of the three final states studied were analyzed and a test of the universality of the photoproduction of electron and muon pairs was performed. The each measured data are in accordance with the predictions of the standard model. (orig./HSI) [de

In this talk, the author discusses the properties of the 3 He spectral function S(K,E) at large momentum K and large separation energy E. He deals in particular with the question how to measure S, and how to understand the physics connected to it. As experimental input he uses (e,e') data. He starts by discussing how to understand (e,e') in terms of properties of S(K,E). For this purpose, an extensive discussion of the scaling function F(y) is needed. When once it is found out how to exploit inclusive scattering, he comes back to exclusive reactions and discusses the relative merits of (e,e'p) and (e,e') in order to investigate how these tools can best complement each other. Some conclusions on the properties of S(K,E) at large K and E, together with some suggestions for future activities follows. (Auth.)

Eukaryotic initiation factor (eIF) 4E, the mRNA 5'-cap-binding protein, mediates the association of eIF4F with the mRNA 5'-cap structure to stimulate cap-dependent translation initiation in the cytoplasm. The assembly of eIF4E into the eIF4F complex is negatively regulated through a family of repressor proteins, called the eIF4E-binding proteins (4E-BPs). eIF4E is also present in the nucleus, where it is thought to stimulate nuclear-cytoplasmic transport of certain mRNAs. eIF4E is transported to the nucleus via its interaction with 4E-T (4E-transporter), but it is unclear how it is retained in the nucleus. Here we show that a sizable fraction (approximately 30%) of 4E-BP1 is localized to the nucleus, where it binds eIF4E. In mouse embryo fibroblasts (MEFs) subjected to serum starvation and/or rapamycin treatment, nuclear 4E-BPs sequester eIF4E in the nucleus. A dramatic loss of nuclear 4E-BP1 occurs in c-Ha-Ras-expressing MEFs, which fail to show starvation-induced nuclear accumulation of eIF4E. Therefore, 4E-BP1 is a regulator of eIF4E cellular localization.

Full Text Available The research extracts sixty seven Hayes and Wheelwright’s practices from the Hayes and Wheel-wright’s six principles. These items formed the basis of a questionnaire sent to over 2800 managers at the SBUs level in the Indonesia’s oil and gas companies. The empirical result indicates that All Hayes and Wheelwright’s six principles collectively have positive impact on an overall construct that may be termed world-class company (WCC. Result also points out that Hayes and Wheelwright’s six principles can be reduced into four meaningful factors of world-class company—as operations strategies—for the Indonesia’s oil and gas industry— Workforce skills and capabilities, Management technical competence, Competing through quality, and Workforce participation. These meaningful factors of WCC were shown to be reliable and valid, and offer new insights into the understanding of operations strategy implementation in an oil and gas industry.Based on the oil and gas managers (the SBU level, operations strategies (four meaningful factors of WCC can be viewed as the effective use of production and operations capability and technology for achieving business and corporate goals. Operations strategy, therefore, is to help a company’s operations organization define the common ground where it can play a proactive and collaborative role with other company functions or cross-functional relationships (Hayes et al., 1996. Oil and gas managers in Indonesia can use these meaningful factors in concert with other critical qual-ity management practices to help them in there word-class company initiatives. Researchers can also use these factors to build structural model linking such factors to various organizational performance measures (i.e., Critical Success Factors of TQM, Operational Excellence, Six Sigma Quality Management, and Good Corporate Governance.Keywords: Hayes and wheelwright’s six principles, Hayes and Wheelwright practices, World
Evaluation of Sample Handling Effects on Serum Vitamin E and Cholesterol Concentrations in Alpacas

Full Text Available Clinical cases of vitamin E deficiencies have been diagnosed in camelids and may indicate that these species are more sensitive to inadequate vitamin E in hay-based diets compared to other ruminant and equine species. In bovine, cholesterol has been reported to affect vitamin E concentrations. In order to evaluate vitamin E deficiencies in camelids, the effects of collection and storage of the blood samples prior to processing were necessary. Reports vary as to factors affecting vitamin E and cholesterol in blood samples, and diagnostic laboratories vary in instructions regarding sample handling. Blood was collected from healthy alpacas and processed under conditions including exposure to fluorescent light, serum and red blood cell contact, tube stopper contact, temperature, and hemolysis. Serum vitamin E and cholesterol concentrations were then measured. Statistical analyses found that the vitamin E concentrations decreased with prolonged contact with the tube stopper and with increasing hemolysis. Vitamin E concentration variations were seen with other factors but were not significant. Time prior to serum separation and individual animal variation was found to alter cholesterol concentrations within the sample, yet this finding was clinically unremarkable. No correlation was seen between vitamin E and cholesterol concentration, possibly due to lack of variation of cholesterol.

Hay-hole falls are a prevalent source of trauma among Anabaptists-particularly Anabaptist youth. We sought to decrease hay-hole falls in South Central Pennsylvania through the development and distribution of all-weather hay-hole covers to members of the at-risk Anabaptist community. Following the creation of a rural trauma prevention syndicate, hay-hole cover prototypes co-designed and endorsed by the Pennsylvania Amish Safety Committee were developed and distributed throughout South Central Pennsylvania. Preintervention and postintervention surveys were distributed to recipients to gain an understanding of the hay-hole fall problem in this population, to provide insight into the acceptance of the cover within the community, and to determine the efficacy of the cover in preventing falls. A total of 231 hay-hole covers were distributed throughout eight rural trauma-prone counties in Pennsylvania. According to preintervention survey data, 52% of cover recipients reported at least one hay-hole fall on their property, with 46% reporting multiple falls (median fall rate, 1.00 [1.00-2.00] hay-hole falls per respondent). The median self-reported distance from hay-hole to ground floor was 10.0 (8.00-12.0) feet, and the median number of hay-holes present on-property was 3.00 (2.00-4.00) per respondent. Postintervention survey data found 98% compliance with hay-hole cover installation and no subsequent reported hay-hole falls. With the support of the Pennsylvania Amish Safety Committee, we developed a well-received hay-hole cover which could effectively reduce fall trauma across other rural communities in the United States.

Study of the decay η→e+e-e+e- with WASA-at-COSY

International Nuclear Information System (INIS)

Yurev, Leonid Sergeewitsch

2011-01-01

This work is dedicated to the study of the double Dalitz decay η→e + e - e + e - . For this rare decay of the η meson only an experimental upper limit for the branching ratio is known. The theoretical prediction is based on Quantum Electrodynamics for the branching ratio is about 2.5 x 10 -5 , which is a factor of three below the experimental upper limit. One of the main points of interest to study this decay is the possibility to measure the transition form factor, which describes the electromagnetic structure of the decaying neutral meson at the η→γ * γ * vertex. In the final state of the decay η→e + e - e + e - there are two lepton pairs, whose squared invariant mass equals the four momenta squared of the virtual photons. The knowledge about the structure of the transition form factor can indicate whether double vector meson dominance is realized in nature, which has important implications for kaon decays and the μ anomalous magnetic moment. Using the WASA at COSY facility it is possible for the first time to determine the branching ratio of the η→e + e - e + e - decay. The data analyzed in this work were taken in the reaction pd→ 3 Heη at 1 GeV kinetic energy and contain ∝10 x 10 6 events of η-mesons. A sample of (30±10) η→e + e - e + e - . event candidates has been extracted, corresponding to a branching ratio of 2.9 x 10 -5 .

Efficient conversion of lignocellulosic biomass to fermentable sugars requires the synergistic action of multiple enzymes; consequently enzyme mixtures must be properly formulated for effective hydrolysis. The nature of an optimal enzyme blends depends on the type of pretreatment employed as well the characteristics of the substrate. In this study, statistical experimental design was used to develop mixtures of recombinant glycosyl hydrolases from thermophilic and anaerobic fungi that enhanced the digestion of alkaline peroxide treated alfalfa hay and barley straw by mixed rumen enzymes as well as commercial cellulases (Accelerase 1500, A1500; Accelerase XC, AXC). Combinations of feruloyl and acetyl xylan esterases (FAE1a; AXE16A_ASPNG), endoglucanase GH7 (EGL7A_THITE) and polygalacturonase (PGA28A_ASPNG) with rumen enzymes improved straw digestion. Inclusion of pectinase (PGA28A_ASPNG), endoxylanase (XYN11A_THITE), feruloyl esterase (FAE1a) and β-glucosidase (E-BGLUC) with A1500 or endoglucanase GH7 (EGL7A_THITE) and β-xylosidase (E-BXSRB) with AXC increased glucose release from alfalfa hay. Glucose yield from straw was improved when FAE1a and endoglucanase GH7 (EGL7A_THITE) were added to A1500, while FAE1a and AXE16A_ASPNG enhanced the activity of AXC on straw. Xylose release from alfalfa hay was augmented by supplementing A1500 with E-BGLUC, or AXC with EGL7A_THITE and XYN11A_THITE. Adding arabinofuranosidase (ABF54B_ASPNG) and esterases (AXE16A_ASPNG; AXE16B_ASPNG) to A1500, or FAE1a and AXE16A_ASPNG to AXC enhanced xylose release from barley straw, a response confirmed in a scaled up assay. The efficacy of commercial enzyme mixtures as well as mixed enzymes from the rumen was improved through formulation with synergetic recombinant enzymes. This approach reliably identified supplemental enzymes that enhanced sugar release from alkaline pretreated alfalfa hay and barley straw.

Full Text Available Determinaram-se as frações dos carboidratos não fibrosos, hidrolisáveis e rapidamente fermentáveis em diferentes dietas e estimou-se a digestibilidade aparente desses nutrientes em dois ensaios com equinos. No ensaio I, utilizaram-se quatro equinos em delineamento quadrado latino 4x4, que consumiram dietas compostas por: feno de tifton-85; feno de tifton-85 e feno de alfafa; feno de tifton-85, feno de alfafa e concentrado; feno de tifton-85 e concentrado. No ensaio II, utilizaram-se 15 equinos em delineamento inteiramente casualizado, que consumiram dietas com 5, 13 e 21% de extrato etéreo, obtidos com a inclusão de diferentes proporções de óleo de soja. A inclusão de concentrado nas dietas aumentou a digestibilidade dos carboidratos não fibrosos e de suas frações, sem afetar a digestibilidade da fibra, enquanto, em dietas com 13% de extrato etéreo, a digestibilidade das frações dos carboidratos fibrosos e a dos não fibrosos não foram afetadas. Nas dietas com 21% de extrato etéreo, houve redução na digestibilidade da celulose e dos carboidratos não fibrosos e suas frações hidrolisáveis e rapidamente fermentáveis. A análise dos carboidratos não fibrosos é uma boa estimativa do valor nutricional dos alimentos, podendo ser incluída na avaliação da qualidade dos alimentos e dietas dos equinos.The fractions of nonfiber carbohydrates, hydrolyzable carbohydrates, and rapidly fermentable carbohydrates of diets and the apparent digestibility of these nutrients were evaluated in horses in two digestion assays.

QCD in e+e- annihilation

International Nuclear Information System (INIS)

Ali, A.

1981-04-01

The promise of e + e - annihilation as an ideal laboratory to test Quantum Chromodynamics, QCD, has been the dominating theme in elementary particle physics during the last several years. An attempt is made to partially survey the subject in deep perturbative region in e + e - annihilation where theoretical ambiguities are minimal. Topics discussed include a review of the renormalization group methods relevant for e + e - annihilation, total hadronic cross section, jets and large-psub(T) phenomena, non-perturbative quark and gluon fragmentation effects and analysis of the jet distributions measured at DORIS, SPEAR and PETRA. My hope is to review realistic tests of QCD in e + e - annihilation - as opposed to the ultimate tests, which abound in literature. (orig.)

The aim of this study was to evaluate the effect of the inclusion of peanut (Arachis pintoi cv. Amarillo) hay in diets based on dwarf elephant grass (DEG, Pennisetum purpureum Schum cv. Kurumi) hay of different regrowth ages on forage intake and digestibility in wether lambs. The experimental treatments consisted of DEG hay with an interval of regrowth of 30 or 45 days offered as the only feed or in mixture with peanut hay (300 g/kg of total dry matter (DM)), which were tested in eight Texel × Suffolk crossbred wethers in a replicated 4 × 4 Latin square experiment. Both organic matter (OM) and digestible OM intakes were higher (P < 0.05) in animals receiving the legume forage. Total apparent OM digestibility was higher (P < 0.05) at an increased grass regrowth age. Ruminal OM digestibility increased (P < 0.05) with legume inclusion and at a higher grass regrowth age. The nitrogen (N) intake was higher (P < 0.05) in legume treatments and lower (P < 0.05) as the grass regrowth age increased, but retention of N was not affected by treatments. Duodenal flow of both, non-ammonia N and microbial N, were not affected by legume inclusion and were lower (P < 0.05) as grass regrowth age increased. The efficiency of rumen microbial protein synthesis (ERMPS) was negatively affected (P < 0.05) by legume inclusion and was lower (P < 0.05) as the grass regrowth age increased. Supplementation of dwarf elephant grass hay cut at the vegetative stage with peanut legume hay improves nutritional supply to wethers due to an increase in the forage intake.

An analytical expression for the spin-averaged amplitude squared of the rare muon decay μ + →e + e - e + ν e ν μ is calculated. Monte Carlo phase space simulation using the analytical expression for the amplitude has been used to get various differential distributions of charged leptons. The approximate analytical expression for the total energy spectrum of charged leptons near the end point is presented. The dependence of the branching ratio on cuts in the total energy of charged leptons is studied taking into account an experimental energy resolution. It is shown that the measured branching ratio is very sensitive to the energy resolution.

Using 4.479×10^{8} ψ(3686) events collected with the BESIII detector, we search for the decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ, where J=0, 1, 2. The decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ are observed for the first time. The measured branching fractions are B(ψ(3686)→e^{+}e^{-}χ_{cJ})=(11.7±2.5±1.0)×10^{-4}, (8.6±0.3±0.6)×10^{-4}, (6.9±0.5±0.6)×10^{-4} for J=0, 1, 2, and B(χ_{cJ}→e^{+}e^{-}J/ψ)=(1.51±0.30±0.13)×10^{-4}, (3.73±0.09±0.25)×10^{-3}, (2.48±0.08±0.16)×10^{-3} for J=0, 1, 2, respectively. The ratios of the branching fractions B(ψ(3686)→e^{+}e^{-}χ_{cJ})/B(ψ(3686)→γχ_{cJ}) and B(χ_{cJ}→e^{+}e^{-}J/ψ)/B(χ_{cJ}→γJ/ψ) are also reported. Also, the α values of helicity angular distributions of the e^{+}e^{-} pair are determined for ψ(3686)→e^{+}e^{-}χ_{c1,2} and χ_{c1,2}→e^{+}e^{-}J/ψ.
Mixing and photoreactivity of dissolved organic matter in the Nelson/Hayes estuarine system (Hudson Bay, Canada)

This work presents the results of a 4-year study (2009-2012) investigating the mixing and photoreactivity of dissolved organic matter (DOM) in the Nelson/Hayes estuary (Hudson Bay). Dissolved organic carbon (DOC), colored DOM, and humic-like DOM decreased with increasing salinity (r2 = 0.70-0.84). Removal of DOM was noticeable at low to mid salinity range, likely due to degradation and/or adsorption to particles. DOM photobleaching rates (i.e., decrease in DOM signal resulting from exposure to solar radiation) ranged from 0.005 to 0.030 h- 1, corresponding to half-lives of 4.9-9.9 days. Dissolved organic matter from the Nelson and Hayes Rivers was more photoreactive than from the estuary where the photodegradation of terrestrial DOM decreased with increasing salinity. Coincident with the loss of CDOM absorption was an increase in spectral slope S, suggesting a decrease in DOM molecular weight. Marked differences in photoreactivity of protein- and humic-like DOM were observed with highly humidified material being the most photosensitive. Information generated by our study will provide a valuable data set for better understanding the impacts of future hydroelectric development and climate change on DOM biogeochemical dynamics in the Nelson/Hayes estuary and coastal domain. This study will constitute a reference on terrestrial DOM fate prior to building additional generating capacity on the Nelson River.
The HayWired Earthquake Scenario

Detweiler, Shane T.; Wein, Anne M.

ForewordThe 1906 Great San Francisco earthquake (magnitude 7.8) and the 1989 Loma Prieta earthquake (magnitude 6.9) each motivated residents of the San Francisco Bay region to build countermeasures to earthquakes into the fabric of the region. Since Loma Prieta, bay-region communities, governments, and utilities have invested tens of billions of dollars in seismic upgrades and retrofits and replacements of older buildings and infrastructure. Innovation and state-of-the-art engineering, informed by science, including novel seismic-hazard assessments, have been applied to the challenge of increasing seismic resilience throughout the bay region. However, as long as people live and work in seismically vulnerable buildings or rely on seismically vulnerable transportation and utilities, more work remains to be done.With that in mind, the U.S. Geological Survey (USGS) and its partners developed the HayWired scenario as a tool to enable further actions that can change the outcome when the next major earthquake strikes. By illuminating the likely impacts to the present-day built environment, well-constructed scenarios can and have spurred officials and citizens to take steps that change the outcomes the scenario describes, whether used to guide more realistic response and recovery exercises or to launch mitigation measures that will reduce future risk.The HayWired scenario is the latest in a series of like-minded efforts to bring a special focus onto the impacts that could occur when the Hayward Fault again ruptures through the east side of the San Francisco Bay region as it last did in 1868. Cities in the east bay along the Richmond, Oakland, and Fremont corridor would be hit hardest by earthquake ground shaking, surface fault rupture, aftershocks, and fault afterslip, but the impacts would reach throughout the bay region and far beyond. The HayWired scenario name reflects our increased reliance on the Internet and telecommunications and also alludes to the

Full Text Available Objetivou-se com este trabalho verificar a resposta de cabras em lactação alimentadas com dietas contendo casca de soja em substituição ao feno de coastcross. Trinta e seis cabras (38±5 dias em lactação; 2,1±0,4 kg/dia foram distribuídas em delineamento experimental de blocos completos casualizados e confinadas por oito semanas. As dietas foram compostas de 50% de volumoso e 50% de concentrado e com o mesmo teor de fibra em detergente neutro. A casca de soja substituiu o feno de coastcross em 0, 33, 67 ou 100% da matéria seca (MS. O consumo de matéria seca e a eficiência alimentar apresentaram resposta quadrática aos teores de casca de soja na dieta. A produção de leite e a variação do peso corporal não foram alteradas, porém a concentração de gordura e lactose do leite aumentou e os tempos gastos com ruminação e mastigação decresceram com a inclusão da casca de soja na dieta. A casca de soja pode substituir totalmente o feno de coastcross em dietas para cabras em lactação, pois essa substituição não prejudica a produção de leite e aumenta o teor de gordura e lactose do leite. Em comparação ao feno picado de coastcross, a casca de soja apresenta menor efetividade em estimular a ruminação e a mastigação.The objective of this experiment was to verify the response of lactating goats fed diets with different levels (content of soybean hulls replacing coastcross hay (Cynodon sp. on performance. Thirty-six lactating Saanen goats (38±5 days of lactation; 2.1±0.4 kg/day were assigned to a randomized complete blocks design and housed for 8 weeks.

Collaboration in highly distributed organizations of people, robots, and autonomous systems is and must be revolutionized by engineering augmentation. The aim is to augment humans’ abilities at work and, through this augmentation, improve organizations’ abilities to accomplish their missions. This book establishes the theoretical foundations and design principles of collaborative e-Work, e-Business and e-Service, their models and applications, design and implementation techniques. The fundamental premise is that without effective e-Work and e-Services, the potential of emerging activities, such as e-Commerce, virtual manufacturing, tele-robotic medicine, automated construction, smart energy grid, cyber-supported agriculture, and intelligent transportation cannot be fully materialized. Typically, workers and managers of such value networks are frustrated with complex information systems, originally designed and built to simplify and improve performance. Even if the human-computer interface for such systems...

Contact interactions are searched for using the differential cross sections for the reactions e + e -→ e + e -, e + e -→ µ + µ -, e + e -→ τ + τ - and e + e -→γγ measured at 12 energies around the Z peak and corresponding to about 20 pb-1 of cumulated luminosity. Four-fermion contact term models assuming various chiralities of lepton currents are fitted to the lepton data and lower limits on the energy scale Λ of such terms are set at 95% c.l. The limits vary in the range 0.9 4.7 TeV, depending on the model and on the lepton flavour. The eeγγ contact terms are searched for assuming various chiralities. Limits on the energy scale Λ between 79 and 130 GeV are extracted from the data. The results are compared and combined with those reported at lower energies.

Given the lack of regulation on marketing of electronic cigarettes (e-cigarettes) in the U.S. and the increasing exchange of e-cigarette-related information online, it is critical to understand how e-cigarette companies market e-cigarettes and how the public engages with e-cigarette information. Results are from a systematic review of peer-reviewed literature on e-cigarettes via a PubMed search through June 1, 2017. Search terms included: "e-cigarette*" OR "electronic cigarette" OR "electronic cigarettes" OR "electronic nicotine delivery" OR "vape" OR "vaping." Experimental studies, quasi-experimental studies, observational studies, qualitative studies, and mixed methods studies providing empirical findings on e-cigarette marketing and communication (i.e., non-marketing communication in the public) were included. One hundred twenty-four publications on e-cigarette marketing and communication were identified. They covered topics including e-cigarette advertisement claims/promotions and exposure/receptivity, the effect of e-cigarette advertisements on e-cigarette and cigarette use, public engagement with e-cigarette information, and the public's portrayal of e-cigarettes. Studies show increases in e-cigarette marketing expenditures and online engagement through social media over time, that e-cigarettes are often framed as an alternative to combustible cigarettes, and that e-cigarette advertisement exposure may be associated with e-cigarette trial in adolescents and young adults. Few studies examine the effects of e-cigarette marketing on perceptions and e-cigarette and cigarette use. Evidence suggests that exposure to e-cigarette advertisements affects perceptions and trial of e-cigarettes, but there is no evidence that exposure affects cigarette use. No studies examined how exposure to e-cigarette communication, particularly misleading or inaccurate information, impacts e-cigarette and tobacco use behaviors. The present article provides a comprehensive review of e

The stability results obtained on Mest have been extended on a machine ten times more powerful: EppE. A plasma stable during its whole confinement time has been observed. This confinement time seems to be limited by the resistive diffusion of the magnetic fields through the plasma.

The 400eV and 1200eV noncoplanar symmetric (e,2e) reaction has been used to measure the momentum distributions of electrons in the individual valence orbitals of ethane as well as to measure the complete separation energy spectra in the valence region. The shapes and relative magnitudes of the momentum distributions agree well with those calculated using the plane wave off-shell impulse approximation and double zeta basis molecular orbital wave functions. The ground state of C 2 H 6 + is shown to be lesub(g) -1 with the vertical ionization potential being 12.25 +- 0.1 eV. Considerable structure due to configuration interaction is observed in the separation energy region 29eV to 55eV. Much of this structure can be assigned to the 2a 1 sub(g) orbital. (author)

This document provides input from the CLIC e+e- linear collider studies to the update process of the European Strategy for Particle Physics. It is submitted on behalf of the CLIC/CTF3 collaboration and the CLIC physics and detector study. It describes the exploration of fundamental questions in particle physics at the energy frontier with a future TeV-scale e+e- linear collider based on the Compact Linear Collider (CLIC) two-beam acceleration technique. A high-luminosity high-energy e+e- collider allows for the exploration of Standard Model physics, such as precise measurements of the Higgs, top and gauge sectors, as well as for a multitude of searches for New Physics, either through direct discovery or indirectly, via high-precision observables. Given the current state of knowledge, following the observation of a \\sim125 GeV Higgs-like particle at the LHC, and pending further LHC results at 8 TeV and 14 TeV, a linear e+e- collider built and operated in centre-of-mass energy stages from a few-hundred GeV up t...

Many horse owners find round bales convenient, less labor intensive, and more affordable than other hay types, but report an inability to control horse BW gain and excessive hay waste. The objectives were to compare hay waste, hay intake, and payback of 9 round-bale feeders and a no-feeder control when used during horse feeding. Nine round-bale feeders were tested: Cinch Net, Cone, Covered Cradle, Hayhut, Hay Sleigh, Ring, Tombstone, Tombstone Saver, and Waste Less. Each feeder design was placed on the ground in a dirt paddock. Five groups of 5 horses were fed in rotation for a 4-d period with each feeder. Every fourth day, groups were rotated among paddocks and a new round bale was placed in each feeder. In the 5 paddocks used, 5 feeders were installed for d 1 through 20, and the remaining 4 feeders and no-feeder control were installed for d 21 through 40. Groups of horses were sequentially assigned to feeders using two 5 × 5 Latin squares, the first for d 1 through 20, the second for d 21 through 40. Horse groups of similar age, BW, breed, and sex were formed from 25 Quarter Horse and Thoroughbred geldings and open mares (means: 11 yr; 541 kg of BW). Hay on the ground surrounding the feeder was collected daily, dried, and weighed. The total amount of hay removed around each feeder for a 4-d period was considered waste. Dry matter intake was estimated as the difference between hay disappearance and waste. Number of months for the reduction in waste to repay feeder cost (payback) were calculated using hay valued at $110/t, and improved feeder efficiency over the control. Feeder design did not affect hay intake (P > 0.05); all feeders resulted in an estimated hay intake of 2.0 to 2.4% BW; the no-feeder control resulted in a reduced intake of 1.3% BW (P = 0.001). Mean percentage of hay waste differed among feeders (P feeder control, 57%. Feeder design also affected payback (P feeder design affected hay waste and payback, but not estimated hay intake or BW change

We consider the single vector leptoquark (LQ) production at e + e - and γe colliders for two values of the center-of-mass energy √s=500GeV and √s=1000 GeV, in a model-independent framework. We find that the cross sections for the single gauge and nongauge vector LQ productions are almost equal. The discovery limit for a single vector LQ production is obtained for both cases. It is shown that in e + e - collisions the single vector LQ production is more favorable than the vector LQ pair production, if the Yukawa coupling constant is κ∼1. copyright 1996 The American Physical Society

We present multi-band results for GRB071010B based on Swift, Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the E src peak - E iso and E src peak - E γ relations, whose studies have been in stagnation due to the lack of the combined estimation of E src peak and long-term optical monitoring. The joint prompt spectral fitting using Swift/Burst Alert Telescope and Suzaku/Wide-band All-sky Monitor data yielded the spectral peak energy as E src peak of 86.5 +6.4 -6.3 keV and E iso of 2.25 +0.19 -0.16 x 10 52 erg with z = 0.947. The optical afterglow light curve is well fitted by a simple power law with temporal index α = -0.60 ± 0.02. The lower limit of temporal break in the optical light curve is 9.8 days. Our multi-wavelength analysis reveals that GRB071010B follows E src peak - E iso but violates the E src peak - E γ and E iso - E src peak - t src jet at more than the 3σ level.

Ile-de-France × Bergamacia crossbred dams grazing on natural grassland were divided into two groups: 1 nutritional supplement 30 days before the parturition (SUPL, and 2 no nutritional supplement (NS. These groups were further subdivided by weaning age of the lambs, which corresponded to either 45 or 60 days. The weaned lambs from each of the previous groups were also divided into different finishing systems: confined and fed a complete diet (CD, confined and fed hay (H and kept on grassland (P. The lambs were slaughtered at 30 kg live weight (CD and P, or at 150 days of age (H. The carcasses were cooled at 4ºC/24h. The analyzed variables were: longissimus dorsi muscle fiber morphophysiology, post mortem myofibrillar fragmentation (at 0, 3 and 7 days post mortem, meat pH and temperature. There was no effect of supplementation of dams or weaning age of the lambs for the evaluated variables. The frequency of slow-oxidative (SO, fast-oxidative-glycolytic (FOG and fast-glycolytic (FG muscle fiber types was not altered by the treatments, but the fiber cross-sectional area was smaller for the lambs finished only on hay, and the meat pH values and temperature were lower and the myofibrill fragment dimensions were smaller. As time maturation increased from 0 to 3 and 7 days post mortem, there was a decrease in the length of the myofibrill fragments. The diet of the lambs which were maintained confined and fed only with hay was nutritionally inferior when compared with all the others, and this changed the quality of the meat compared to the finishing systems on grassland or confined and fed complete diet.Avaliou-se a influência dos níveis nutricionais da ovelha antes do parto, da idade à desmama e do sistema de terminação sobre as fibras musculares

This paper describes briefly the theory of (e,2e) of atoms and molecules. Subsequently, introduces a simple model for a one-dimensional crystal. The (e,2e) spectra is calculated as would be measured for this hypothetical case, and use this model to make a link between (e,2e) spectroscopy as applied to atoms and molecules and this technique as applied to solids. Slight modifications of the model allow for the simulation of the effects of different band-structures on the (e,2e) spectra. Special attention is paid to the difference in the type of information obtained from (e,2e) spectroscopy and that obtained from angular resolved photo emission. 19 refs., 9 figs.
The future e+e- colliders

At present, the highest energy e + e - colliders are the SLC and LEP. In this paper their future improvement programs for increasing luminosity and/or energy, and the use of longitudinally polarized beams at the interaction point (IP) are discussed. An e + e - collider in the SSC tunnel does not seem to be an attractive option, on both technical and economical grounds, and with LEP, circular colliders have reached the sensible limit of size and cost. Linear colliders which have, in principle, no high energy limit, must overcome a new set of technical problems having to do with beam power limitations, emittance control, superstrong focusing at the IP, strong bunch-bunch interactions at the IP and related backgrounds

Feasible designs are well advanced for high-luminosity e + e - storage rings which produce B 0 bar B 0 pairs either at rest or, in what appears to be a more promising option, boosted in the detector frame. Facilities which could provide samples of 30--100 fb -1 per year on the Υ(4S) will be proposed in early 1991. Here we examine the principal physics goal of such B Factories, namely CP violation in the b system. Methods in a variety of channels, estimated event samples, and detector requirements are all considered. We conclude that the physics argument for an e + e - B Factory is well documented, and compelling. 50 refs., 22 figs., 10 tabs

Stress granules (SGs) arise as a consequence of cellular stress, contain stalled translation preinitiation complexes, and are associated with cell survival during environmental insults. SGs are dynamic entities with proteins relocating into and out of them during stress. Among the repertoire of proteins present in SGs is eukaryotic initiation factor 4E (eIF4E), a translation factor required for cap-dependent translation and that regulates a rate-limiting step for protein synthesis. Herein, we demonstrate that localization of eIF4E to SGs is dependent on the presence of a family of repressor proteins, eIF4E-binding proteins (4E-BPs). Our results demonstrate that 4E-BPs regulate the SG localization of eIF4E.

Full Text Available Objective The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. Methods Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration containing 60% (dry matter [DM] basis of basal starter feed and 40% (DM basis of forage, but varied in composition of forage source including i alfalfa (40% DM, AH; ii alfalfa hay (26.7% DM+oat hay (13.3% DM; OH; iii alfalfa hay (26.7% DM+corn silage (13.3% DM; WS. Results Dry matter intake was not different among treatment groups (p>0.05. However, BW (p<0.05 and average daily gain (p<0.05 of calves fed AH and OH were greater than WS-fed calves, whereas heart girth was greater in OH-fed calves than those fed AH and WS (p<0.05. Ruminal fermentation parameters including proportion of butyric acid, acetated-to-propionate ratio, concentration of total volatile fatty acid, protozoal protein, bacterial protein, and microbial protein in rumen were the highest in OH (p<0.05 and the lowest in WS. Compared with the AH and WS, feeding oat hay to postweaning calves increased crude protein digestibility (p<0.05, and decreased duration of diarrhea (p<0.05 and fecal index (p<0.05. Conclusion Our results suggested that partially replacing alfalfa hay with oat hay improved ruminal fermentation, nitrogen utilization, and reduced incidence of diarrhea in post-weaning dairy calves.

We present a detailed treatment of the theoretical and experimental aspects of the symmetric (e,2e) reaction in atoms, molecules and solids. Two experimental arrangements are described for measuring angular correlations and separation energy spectra, the one arrangement employing coplanar and the other noncoplanar symmetric kinematics. The latter arrangement is shown to be particularly suitable for extracting structure information. The basic approximation, the factorized distorted-wave off-shell impulse approximation with fully distorted waves, is shown to correctly describe the reaction in some test cases, as does the phase distortion approximation. At energies of the order of 1200 eV the simple eikonal and plane wave approximations adequately describe the valence shell cross sections for light atoms and molecules containing first row elements. Energy independent structure information is obtained on: (a) shapes and magnitudes of the square of the momentum space wave functions for individual electron orbitals; (b) separation energies for individual ion eigenstates; (c) the characteristic orbital of each state; and (d) spectroscopic factors describing the probability that an eigenstate contains the principal configuration of a hole in the characteristic orbital for each eigenstate. Comparison is made with photoelectron spectroscopy and Compton scattering, since they separately yield some of the information obtained by the (e,2e) method. A brief summary is given of other electron-electron coincidence experiments. (author)

Dissociation of eIF4E-binding protein 2 (4E-BP2 from eIF4E independent of Thr37/Thr46 phosphorylation in the ischemic stress response.

Directory of Open Access Journals (Sweden)

María I Ayuso

Full Text Available Eukaryotic initiation factor (eIF 4E-binding proteins (4E-BPs are translational repressors that bind specifically to eIF4E and are critical in the control of protein translation. 4E-BP2 is the predominant 4E-BP expressed in the brain, but their role is not well known. Here, we characterized four forms of 4E-BP2 detected by two-dimensional gel electrophoresis (2-DGE in brain. The form with highest electrophoretic mobility was the main form susceptible to phosphorylation at Thr37/Thr46 sites, phosphorylation that was detected in acidic spots. Cerebral ischemia and subsequent reperfusion induced dephosphorylation and phosphorylation of 4E-BP2 at Thr37/Thr46, respectively. The induced phosphorylation was in parallel with the release of 4E-BP2 from eIF4E, although two of the phosphorylated 4E-BP2 forms were bound to eIF4E. Upon long-term reperfusion, there was a decrease in the binding of 4E-BP2 to eIF4E in cerebral cortex, demonstrated by cap binding assays and 4E-BP2-immunoprecipitation experiments. The release of 4E-BP2 from eIF4E was without changes in 4E-BP2 phosphorylation or other post-translational modification recognized by 2-DGE. These findings demonstrated specific changes in 4E-BP2/eIF4E association dependent and independent of 4E-BP2 phosphorylation. The last result supports the notion that phosphorylation may not be the uniquely regulation for the binding of 4E-BP2 to eIF4E under ischemic stress.

Hopes for detecting supersymmetry in e + e - annihilations are reviewed using examples from several workshops on present and future colliders. MSSM, the simplest model of minimal supersymmetry with grand unification is studied. Chances for discovering the higgs sector at LEP and at a future 500 GeV e + e - linear collider are cited along with ways for measuring the higgs' properties; similary for the supersymmetric partners of the presently-known elementary particles. Once discovered, examples are given as to how to attack the spartner spectroscopy and MSSM parameters at the e + e - linear collider. The complementarity of these measurements to those at pp colliders is emphasized. (orig.)

The effect of feeding flaxseed or algae supplements to lambs on muscle antioxidant potential (vitamin E), major fatty acid groups, lipid oxidation and retail colour was investigated. Lambs (n=120) were randomly allocated to one of 4 dietary treatments according to liveweight and fed the following diets for eight weeks: Annual ryegrass hay [60%]+subterranean clover hay [40%] pellets=Basal diet; Basal diet with flaxseed (10.7%)=Flax; Basal diet with algae (1.8%)=Algae; Basal diet with flaxseed (10.7%) and algae (1.8%)=FlaxAlgae. Flaxseed or algae supplementation significantly affected major fatty acid groups in muscle. The addition of algae (average of Algae and FlaxAlgae) resulted in lower vitamin E concentration in muscle (Palgae (average of Basal and Flax). Increasing muscle EPA+DHA by algae supplementation significantly increased lipid oxidation, but retail display colour of fresh meat was not affected. Copyright © 2015 Elsevier Ltd.

The time-evolution of jets in hadronic e+ e- events at LEP is investigated in both position- and momentum-space, with emphasis on effects due to color flow and particle correlations. We address dynamical aspects of the four simultanously-evolving, cross-talking parton cascades that appear in the reaction e+ e- --> .gamma./Z.sup(0) --> W+W- --> q1 q~2 q3 q~4, and compare with the familiar two-parton cascades in e+ e- --> Z.sup(0) --> q1 q~2. We use a QCD statistical transport approach, in which the multiparticle final state is treated as an evolving mixture of partons and hadrons, whose proportions are controlled by their local space-time geography via standard perturbative QCD parton shower evolution and a phenomenological model for non-perturbative parton-cluster formation followed by cluster decays into hadrons. Our numerical simulations exhibit a characteristic "inside-outside" evolution simultanously in position and momentum space. We compare three different model treatments of color flow, and find large ...

We also evaluate the cross section of charmed baryon pair production. Near their respective thresholds charmed and uncharmed baryon pair production are predicted to constitute comparable fractions of the total hadronic cross section. The calculated cross sections indicate that the interference of direct and 1-photon decay of the PSI-particles into baryon pairs is small. (orig.) [de

Full Text Available The aim of this study was to identify the factors which affect the e-loyalty of online customers to the websites they shop from. In this context, the e-service quality that customers perceive from the website, the level of e-satisfaction associated with the website, and the e-trust were defined as the variables that determine the e-loyalty. A model was proposed based on these variables. Using the E-S-Qual scale, the execution and e-quality of the services provided by the website were measured based on the dimensions of security, efficiency system availability, and fulfillment and the effect of e-service quality on both the e-satisfaction and e-trust were demonstrated. The impact of e-trust and e-satisfaction on e-loyalty was also investigated. A total of 594 people living in the city of Eskişehir, Turkey, who shopped from the hepsiburada.com internet store, participated in the study. The study results indicate that the customers’ perception of website’s e-quality is an important determinant in creating e-trust and e-satisfaction in the website’s services, and that the resulting perception of e-trust and e-satisfaction in turn determines e-customer loyalty.

We investigate some processes of the associated production of a neutral top-pion Π t 0 with a pair of fermions (e + e - →ff-barΠ t 0 ) in the context of top-color-assisted technicolor (TC2) theory in the future e + e - colliders. The studies show that the largest cross sections of the processes e + e - →f ' f ' Π t 0 (f ' =u,d,c,s,μ,τ) could only reach the level of 0.01 fb; we can hardly detect a neutral top-pion through these processes. For the processes e + e - →e + e - Π t 0 , e + e - →tt-barΠ t 0 , and e + e - →bb-barΠ t 0 , the cross sections of these processes are at the level of a few fb for the favorable parameters, and a few tens, even hundreds, of neutral top-pion events can be produced at future e + e - colliders each year through these processes. With the clean background of the flavor-changing tc-bar channel, the top-pion events can possibly be detected at the planned high luminosity e + e - colliders. Therefore, such neutral top-pion production processes provide a useful way to detect a neutral top-pion and test the TC2 model directly

The Kingdom of Saudi Arabia (KSA) has witnessed unprecedented growth in higher education and E-learning in recent times. In the last five years, one university and five colleges have been commissioned every month; 800 scholarships have been awarded every month for overseas study; a national center for E-learning has been established; and E-units or departments have been set-up in almost every university. E-learning has become important for discussion to quote Shakespeare 'To E or not to E that is the question.' To examine current and future developments and challenges of E-learning in KSA. A qualitative approach was used to explore views of 30 senior academicians involved in E-learning during their attendance at a two-week course on the subject. All participants considered themselves as decision makers on E-learning in their units or departments. They felt that E-learning had come to stay, but acknowledged challenges in respect of resources, organization, management, and information technology. The fast development of E-learning poses many challenges. Clear vision and strategic planning with prospective E-learners in mind are essential to make E-learning programs cost effective.

Eukaryotic translation initiation requires cooperative assembly of a large protein complex at the 40S ribosomal subunit. We have resolved a budding yeast initiation complex by cryo-EM, allowing placement of prior structures of eIF1, eIF1A, eIF3a, eIF3b and eIF3c. Our structure highlights differences in initiation-complex binding to the ribosome compared to that of mammalian eIF3, demonstrates a direct contact between eIF3j and eIF1A and reveals the network of interactions between eIF3 subunits.

A completely randomized design, with four replicates, in a split-plot arrangement was used. The plots were the experimental treatments (5, 7, 10mm and whole hay and the subplots were the times of collection (0, 2, 4, 6, 8h. The use of diets including hay with particle sizes of 5mm and whole, did not affect (P>0,05 the ruminal pH; average values were 6.14 and 6.61, respectively. A linear reduction in the ruminal pH was verified in the steers fed on diets constituted by 10mm particles. For the diets including Tifton hay with particle size of 7mm, it was observed a quadratic effect, where the minimum pH (5.39 was observed 8:00 h after the feed was furnished. Concentrations of N-NH3 were affected by collection time in a quadratic way. Maximum concentrations of N-NH3, 15.55, 15.83, 18.32, 12.0 mg/100 mL, were observed at 4:28, 3:58, 2:99 and 2:80h after feeding, for the diets including Tifton 85 hay with 5, 7, 10mm and whole particle sizes, respectively.

Animals with partial alopecia were seen frequently in a breeding colony of guinea pigs. No pathologic aetiology could be determined. An influence of nutrition on the density of the hair coat was considered. Breeding groups were fed one of the commercial guinea pig diets of differing composition, with or without the addition of hay. Observation occurred over a period of months and the quality of the hair coat was evaluated periodically using a semi-quantitative scoring system. More extensive and more frequent fur defects were found is guinea pigs receiving a breeding diet with a high content of crude protein (23%) and a low level of crude fibre (12%), offered hay only restrictively compared with animals receiving a diet with a lower content of crude protein (15.5%) and a higher level of crude fibre (19.5%), offered the same amount of hay. The amount of hay offered is of paramount importance. Animals fed only the diet with the higher level of crude fibre (19.5%), according to the manufacturer's instructions as a complete food, without the addition of hay, showed a less dense hair coat within 4 weeks. In our colony a group of five breeding animals and their young required 200 g of hay daily in order to improve their hair coat quality to normal. Conversely, animals receiving less hay had progressively deteriorating hair coat density. Not only the amount of hay offered, but also the accessibility for all animals plays a role in preventing alopecia in guinea pigs. In larger cages (twice the usual ground surface area) fur defects were seen when the same amount of hay (200 g) was offered in only one central area, rather than spread out evenly throughout the cage. Hair loss was observed to be the result of trichophagia between adult animals kept in the same cage. The need for crude fibre of breeding animals does not appear to be completely met by pellets rich in fibre segments.

In supersymmetric extensions of the Standard Model with a very light gravitino, the effective theory at the weak scale should contain not only the goldstino G-tilde, but also its supersymmetric partners, the sgoldstinos. In the simplest case, the goldstino is a gauge-singlet and its superpartners are two neutral spin-0 particles, S and P. We study possible signals of massive sgoldstinos at e + e - colliders, focusing on those that are most relevant at LEP energies. We show that the LEP constraints on e + e - →γS (γP), ZS (ZP) or e + e - S (e + e - P), followed by S(P) decaying into two gluon jets, can lead to stringent combined bounds on the gravitino and sgoldstino masses

A ciliate protozoa suppression can reduce methane production increasing the energy efficiency utilization by ruminants. The physicochemical characteristics of rumen fluid and the profile of the rumen protozoa populations were evaluated for sheep fed banana leaf hay in replacement of the Cynodon dactylon cv. vaqueiro hay. A total of 30 male sheep were raised in intensive system during 15 days of adaptation and 63 days of experimental period. The animals were distributed in a completely randomized design that included six replicates of five treatments with replacement levels (0, 25, 50, 75, and 100%) of the grass vaquero for the banana leaf hay. Samples of fluid were collected directly from the rumen with sterile catheters. Color, odor, viscosity, and the methylene blue reduction potential (MBRP) were evaluated and pH estimated using a digital potentiometer. After decimal dilutions, counts of genus protozoa were performed in Sedgewick Rafter chambers. The averages of pH, MBRP, color, odor, and viscosity were not influenced by the inclusion of the banana leaf hay. However, the total number of protozoa and Entodinium spp. population significantly decreased at 75 and 100% inclusions of banana leaf hay as roughage.

2002-01-01

Over two years, replicate plots of lentils (Lens culinaris L.) were treated before seeding with methabenzthiazuron at a rate of 0.5 kg a.i. ha-1. In each year representative soil, lentil and hay samples were randomly collected from plots of each treatment. Soil samples were tested for residues 24 hours after treatment and harvest. Lentil and hay samples were tested at harvest. A cleanup step was conducted after extraction. Gas chromatograph equipped with a nitrogen/phosphorus detector was used to detect methabenzthiazuron. Overall average of residue levels in soil decreased significantly from 1.16+-0.15 mg kg, 24 hours after treatment, 0.12 +-0.01 mg kg at harvest. No significant difference in the maximum average residue was found in lentil and hay samples collected from various plots and tested at harvest (0.10+-0.01 and 0.19 +-0.02 mg kg in lentils and hay, respectively). Recovery tests were conducted with each group of samples tested in order to determine the efficiency of analytical procedure. (author)
The correction of the littlest Higgs model to the Higgs production process e+e-→e+e-H at the ILC

Wang, Xuelei; Liu, Yaobei; Chen, Jihong; Yang, Hua

2007-01-01

The littlest Higgs model is the most economical one among various little Higgs models. In the context of the littlest Higgs model, we study the process e + e - →e + e - H at the ILC and calculate the correction of the littlest Higgs model to the cross section of this process. The results show that, in the favorable parameter spaces preferred by the electroweak precision data, the value of the relative correction is in the range from a few percent to tens percent. In most cases, the correction is large enough to reach the measurement precision of the ILC. Therefore, the correction of the littlest Higgs model to the process e + e - →e + e - H might be detected at the ILC, which will give an ideal way to test the model. (orig.)
Higgs-strahlung and WW fusion in e+e- collisions

Kilian, W.; Kraemer, M.; Zerwas, P.M.

1995-12-01

Higgs-strahlung e + e - →ZH and WW fusion e + e - → anti νν e H are the most important mechanisms for the production of Higgs bosons in e + e - collisions at LEP2 and future e + e - linear colliders. We have calculated the cross sections and energy/angular distributions of the Higgs boson for these production mechanisms. When the Z boson decays into (electron-)neutrinos, the two production amplitude interfere. In the cross-over region between the two mechanisms the interference term is positive and of the same size as the individual cross sections, thus enhancing the production rate. (orig.)

The HayWired earthquake scenario, led by the U.S. Geological Survey (USGS), anticipates the impacts of a hypothetical magnitude-7.0 earthquake on the Hayward Fault. The fault is along the east side of California’s San Francisco Bay and is among the most active and dangerous in the United States, because it runs through a densely urbanized and interconnected region. One way to learn about a large earthquake without experiencing it is to conduct a scientifically realistic scenario. The USGS and its partners in the HayWired Coalition and the HayWired Campaign are working to energize residents and businesses to engage in ongoing and new efforts to prepare the region for such a future earthquake.

Full Text Available CONTEXTO: Embora existam muitos estudos relacionando o contexto religioso com a saúde física e mental, há poucas pesquisas sobre a interface entre religiosidade/espiritualidade (R/E e personalidade. OBJETIVOS: O objetivo principal foi revisar as evidências empíricas de investigações sobre a relação entre religiosidade, espiritualidade e personalidade. MÉTODOS: Foi realizado um levantamento da produção acadêmica por meio das bases de dados virtuais: PubMed e PsychInfo, com artigos indexados até janeiro de 2008 e utilizando as combinações: "personality and spiritu*" e "personality and religio*" Além disso, foram pesquisados os artigos presentes em uma metanálise sobre o tema. RESULTADOS: Alta Religiosidade está associada a baixo Psicoticismo e a alta Amabilidade e Conscienciosidade. Conscienciosidade em adolescentes pode ser um preditor significante para a maior religiosidade na adultez jovem. E a dimensão de Religiosidade é mais provável candidata a residir além dos cinco grandes fatores de personalidade. CONCLUSÃO: A crença em uma dimensão de Religiosidade, em uma realidade transcendente ou em um Deus pessoal, em alguns casos, parece não possuir correspondências entre quaisquer dos cinco fatores de personalidade. Isso parece indicar que a R/E seja um potencial sexto fator de personalidade que não está presente nos modelos de personalidade atuais.BACKGROUND: Although there are many studies linking the religious context with fisical and mental health, there is little research on the interface between religiousness/spirituality and personality.

Full Text Available The main requirement for preserving European hay meadows in good condition is through prerequisite cut management. However, monitoring these practices on a larger scale is very difficult. Our study analyses the use of MODIS vegetation indices products, namely EVI and NDVI, to discriminate cut and uncut meadows in Slovakia. We tested the added value of simple transformations of raw data series (seasonal statistics, first difference series, compared EVI and NDVI, and analyzed optimal periods, the number of scenes and the effect of smoothing on classification performance. The first difference series transformation saw substantial improvement in classification results. The best case NDVI series classification yielded overall accuracy of 85% with balanced rates of producer’s and user’s accuracies for both classes. EVI yielded slightly lower values, though not significantly different, although user accuracy of cut meadows achieved only 67%. Optimal periods for discriminating cut and uncut meadows lay between 16 May and 4 August, meaning only seven consecutive images are enough to accurately detect cutting in hay meadows. More importantly, the 16-day compositing period seemed to be enough for detection of cutting, which would be the time span that might be hopefully achieved by upcoming on-board HR sensors (e.g., Sentinel-2.

e++e-→νsub(e)+anti νsub(e)+γ process in the gauge theories

Dzhafarov, I.G.; Mustafaev, Kh.A.; Sultanov, S.F.

1977-01-01

The e + +e - →νsub(e)+anti νsub(e)+γ process has been treated within the framework of the unified theory of weak and electromagnetic interractions (the Weinberg-Salam model). The analytical expressions for the photoproduction differential cross section are presented for two energy ranges: the range of relatively low energies and that of the resonance production expected due to the Z bozon exchange. Angular and energy distributions of photons produced in the process under consideration are investigated. The photoproduction differential cross section is by two-three orders of magnitude higher for the resonance energy, than the cross section for the same process, which is predicted by the local four-fermion V-A theory. The formulae obtained can be used also to describe the μ + +μ - →νsub(μ)+anti νsub(μ)+γ reaction

Lee, T.-S. H.

1998-01-01

A dynamical approach for using the γN -> πN and N(e,e primeπ) reactions to test the chiral constituent quark model is reviewed. Recent results for the Δ excitations and predictions for future experiments are presented. It is shown that the polarization observables of d(e,e primeπ) reactions are useful for investigating the NΔ interactions which are crucial in exploring the Δ components in nuclei and the properties of Δ-rich systems created in relativistic heavy-ion collisions
"Doidas e putas”: usos das categorias travesti e transexual

Directory of Open Access Journals (Sweden)

Bruno Cesar Barbosa

Full Text Available Neste artigo discuto os usos das categorias travesti e transexual com base em trabalho de campo realizado entre 2008 e 2009 com participantes das reuniões denominadas Terças Trans. A questão central que norteou a análise foi como as diferentes pessoas observadas utilizavam categorias relacionadas a identidades sexuais e de gênero e como acionavam e articulavam diversas associações convencionais nesse processo para produzir sentidos e diferenças acerca destas categorias. Embora as convenções do discurso médico sejam referências centrais para a definição de corpos, subjetividades e identidades das pessoas pesquisadas, foi possível observar também uma variedade de reelaborações e deslocamentos de sentidos. Procuro desenvolver o argumento de que travesti e transexual são categorias performativas, e que tal performatividade não se esgota apenas em enunciados de gênero e sexualidade, mas também pode ser expressa por meio de articulações contingentes que remetem a diferenças de classe, cor/raça e geração.
Helper component proteinase of the genus Potyvirus is an interaction partner of translation initiation factors eIF(iso)4E and eIF4E and contains a 4E binding motif.

The multifunctional helper component proteinase (HCpro) of potyviruses (genus Potyvirus; Potyviridae) shows self-interaction and interacts with other potyviral and host plant proteins. Host proteins that are pivotal to potyvirus infection include the eukaryotic translation initiation factor eIF4E and the isoform eIF(iso)4E, which interact with viral genome-linked protein (VPg). Here we show that HCpro of Potato virus A (PVA) interacts with both eIF4E and eIF(iso)4E, with interactions with eIF(iso)4E being stronger, as judged by the data of a yeast two-hybrid system assay. A bimolecular fluorescence complementation assay on leaves of Nicotiana benthamiana showed that HCpro from three potyviruses (PVA, Potato virus Y, and Tobacco etch virus) interacted with the eIF(iso)4E and eIF4E of tobacco (Nicotiana tabacum); interactions with eIF(iso)4E and eIF4E of potato (Solanum tuberosum) were weaker. In PVA-infected cells, interactions between HCpro and tobacco eIF(iso)4E were confined to round structures that colocalized with 6K2-induced vesicles. Point mutations introduced to a 4E binding motif identified in the C-terminal region of HCpro debilitated interactions of HCpro with translation initiation factors and were detrimental to the virulence of PVA in plants. The 4E binding motif conserved in HCpro of potyviruses and HCpro-initiation factor interactions suggest new roles for HCpro and/or translation factors in the potyvirus infection cycle.
Search for fractionally charged particles in e+e- annihilations

We have searched for the production of free Q = +-1/3e, Q = +-2/3e and Q = +-4/3e particles produced in e + e - collisions at a center-of-mass energy of 29 GeV in 77 pb -1 of data collected by the time projection chamber at PEP. No evidence has been found for the production of these particles. Upper limits are established on the inclusive cross section for the production of Q = +-1/3e, Q = +-2/3e, and Q = +-4/3e particles in the mass range 1.0 to 13 GeV/c 2 , improving upon previously established limits. 58 references

Next-to-leading order corrections to e+e-→W+W-Z and e+e-→ZZZ

Boudjema, Fawzi; Hao Sun; Ninh, Le Duc; Weber, Marcus M.

2010-01-01

We calculate the one-loop electroweak corrections to e + e - →W + W - Z and e + e - →ZZZ and analyze their impacts on both the total cross section and some key distributions. These processes are important for the measurements of the quartic couplings of the massive gauge bosons which can be a window on the mechanism of spontaneous symmetry breaking. We find that even after subtracting the leading QED corrections, the electroweak corrections can still be large, especially as the energy increases. We compare and implement different methods of dealing with potential instabilities in the routines pertaining to the loop integrals. For the real corrections we apply a dipole subtraction formalism and compare it to a phase-space slicing method.

Biopolítica e Desenvolvimento? Foucault e Agamben sobre Estado, Governo e Violência

Full Text Available Este artigo analisa as relações entre biopolítica e desenvolvimento sob o ângulo das noções de Estado, governo e violência. O objetivo consiste em examinar elementos analíticos que gravitam em torno de perspectivas críticas do desenvolvimento buscando um eixo interpretativo sobre a ambivalência das ações do Estado a partir de duas possibilidades teóricas que convergem no pensamento de Giorgio Agamben: a análise do biopoder e do governo em Foucault e as articulações entre violência e lei que remetem a Walter Benjamin. A reflexão sobre os argumentos teóricos é realizada examinando-se dados oriundos de pesquisa de abordagem qualitativa sobre políticas para a agricultura ecológica no sul do Brasil. As conclusões mostram que o desenvolvimento e seus benefícios podem ser problematizados pelo olhar do biopoder e da violência, que reconfiguram o que seja desenvolvimento, menos como expansão do bem-estar e mais como impulso modernizante de mudança que se ampara em administrar a vida.

The aplication of the (e,2e) technique is discussed in the framework of (e,2e) on molecular hydrogen. It is shown that the technique is sufficiently sensitive to distinguish between simple wavefunctions and those containing configuration interactions. By comparing the data on H 2 and D 2 is shown that the Born-Oppenheimer approximation is confirmed to an accuracy of about 3 per cent. The data is also used to contrast other methods of determining electron momentum distributions in molecules. Data on methane, carbon monoxide and molecular nitrogen is also presented. (author)
A different voice: Mary Hays's the Memoirs of Emma Courtney.

Science.gov (United States)

Sharma, A

2001-01-01

Mary Hays wrote in the decade of the 1790s, a period of intense creative flowering in England. Writing in a period enshrined to the works of the canonical Wordsworth and Coleridge, Hays explored through her Jacobinical novel, The Memoirs of Emma Courtney, the contentious relationship between self and society. Like other Jacobin women writers - Elizabeth Inchbald, Charlotte Smith and Mary Wollstonecraft - Mary Hays too used her novel to explode the insidious connection between education and gender construction. Emma Courtney is a landmark novel that wrestles with the paradigm of decorum and propriety which disallows women from voicing their aspirations. In the process, Hays merges the plots of the domestic novel of courtship and love with the novel of ideas to create a searing portrait of women's intellectual confinement and psychic dissonance in a society that only projects them in terms of their gender construction. Memoirs of Emma Courtney is a remarkable novel in its depiction of the emotional imbalance created by thwarted desire: intellectual and sexual.

We study one possible production mechanism for the hidden-charm pentaquark via a color-octet c\\bar{c} pair fragmentation in e + e - collision. The pentaquark production at B factory energy is dominated by {e}+{e}-\\to c\\bar{c}g\\to {P}c+X, while at Z 0 pole energy, there are several partonic processes playing significant role. Our results show that it is possible to search for the direct pentaquark production signal at e + e - colliders, which is important to understand the properties of pentaquark.

O hipertexto e o estranho: causas e efeitos

Full Text Available Segundo Barthes, o texto ideal é aquele que se apresenta em redes múltiplas e que se entrelaça, sem comprometer sua estrutura. Redes ou nós que fazem com que esse texto ofereça um universo de significantes e significados, ou seja, não tem início, é reversível, possui diversas entradas e isso se choca com a noção tradicional de práticas de leitura e escrita linear. Nesse sentido, nosso objetivo é demonstrar como o hipertexto causa "estranheza" partindo do conceito de “estranho” apontado por Freud em seu artigo Das Unheimlich (1919, a fim de que possamos compreender como essa relação obra/leitor vem sendo alterada e provocando sensações de dinamicidade distintas da inércia do papel, como observamos em O Jogo da Amarelinha (1963, de Julio Cortázar, e em textos de temática fantástica, como em E.T.A.

No significant signals are observed and the corresponding upper limits on the branching fractions at the 90% confidence level are determined to be B (J /ψ →D0e+e-+c .c .)<8.5 ×10-8 and B (ψ (3686 )→D0e+e-+c .c .)<1.4 ×10-7 , respectively. Our limit on B (J /ψ →D0e+e-+c .c .) is more stringent by 2 orders of magnitude than the previous results, and B (ψ (3686 )→D0e+e-+c .c .) is measured for the first time.

Resistive plate chambers (RPCs) will be installed as one of the important tracking detectors both in the endcap and barrel area CMS muon stations. These stations will be exposed to high gamma, neutron and positron/electron background radiation environment during the LHC machine operation. For the safe operation of these detectors, it is necessary to monitor these kinds of radiation. A simulation test has been carried out with the RPC at e + /e - fluxes using the dose and fluence equivalent to LHC 10 years operation. The simulation studies of RPC to e + /e - of energy 0.1 < E < 100 MeV have been performed using the GEANT 3.21 and GEANT4 Monte Carlo packages. By employing these two packages, good agreement of the simulation results is attained
Translation Initiation Factor eIF4E and eIFiso4E Are Both Required for Peanut stripe virus Infection in Peanut (Arachis hypogaea L.).

Peanut stripe virus (PStV) belongs to the genus Potyvirus and is the most important viral pathogen of cultivated peanut ( Arachis hypogaea L.). The eukaryotic translation initiation factor, eIF4E, and its isoform, eIF(iso)4E, play key roles during virus infection in plants, particularly Potyvirus . In the present study, we cloned the eIF4E and eIF(iso)4E homologs in peanut and named these as PeaeIF4E and PeaeIF(iso)4E , respectively. Quantitative real-time PCR (qRT-PCR) analysis showed that these two genes were expressed during all growth periods and in all peanut organs, but were especially abundant in young leaves and roots. These also had similar expression levels. Yeast two-hybrid analysis showed that PStV multifunctional helper component proteinase (HC-Pro) and viral protein genome-linked (VPg) both interacted with PeaeIF4E and PeaeIF(iso)4E. Bimolecular fluorescence complementation assay showed that there was an interaction between HC-Pro and PeaeIF4E/PeaeIF(iso)4E in the cytoplasm and between VPg and PeaeIF4E/PeaeIF(iso)4E in the nucleus. Silencing either PeaeIF4E or PeaeIF(iso)4E using a virus-induced gene silencing system did not significantly affect PStV accumulation. However, silencing both PeaeIF4E and PeaeIF(iso)4E genes significantly weakened PStV accumulation. The findings of the present study suggest that PeaeIF4E and PeaeIF(iso)4E play important roles in the PStV infection cycle and may potentially contribute to PStV resistance.
Environmental impact assessment of alfalfa (Medicago sativa L.) hay production.

On-farm production of hay and high-protein-content feed has several advantages such as diversification of on-farm cultivated crops, reduction of off-farm feed concentrates transported over long distances and a reduction in runoff during the winter season if grown crops are perennial. Among those crops cultivated for high-protein-content feed, alfalfa (Medicago sativa L.) is one of the most important in the Italian context. Nevertheless, up to now, only a few studies have assessed the environmental performance of alfalfa hay production. In this study, using the Life Cycle Assessment approach, the environmental impact of alfalfa hay production in Northern Italy was analyzed. More in detail, two production practices (without and with irrigation) were compared. The results show that alfalfa hay production in irrigated fields has a better environmental performance compared to non-irrigated production, mainly because of the yield increase achieved with irrigation. In particular, for the Climate Change impact category, the impact is equal to 84.54 and 80.21kgCO 2 /t of hay for the scenario without and with irrigation, respectively. However, for two impact categories (Ozone Depletion and Human Toxicity-No Cancer Effect), the impact of irrigation completely offsets the yield increase, and the cultivation practice without irrigation shows the best environmental performance. For both scenarios, the mechanization of harvest is the main environmental hotspot, mostly due to fuel consumption and related combustion emissions. Wide differences were highlighted by comparing the two scenarios with the Ecoinvent process of alfalfa hay production; these differences are mostly due to the cultivation practice and, in particular, to the more intensive fertilization in Swiss production.

Chanowitz, M.S.

1992-01-01

A survey is presented of the physics opportunities at TeV e + e - linear colliders. Examples are given of physics that might emerge in e + e - collisions and in γγ collisions using the back-scattered laser technique, including γγ → ZZ scattering as a probe of ultraheavy quanta. The second portion of the talk focuses on physics that must emerge at or below the TeV scale--the mechanism of electroweak symmetry breaking. In particular a very rough estimate is presented of the most challenging possible signal of symmetry breaking, strong WW scattering, as a function of collider energy. A subtheme, made explicit in the concluding section, is the continuing complementarity of e + e - and pp colliders in the domain of TeV physics

Background Infections of Echinococcus granulosus sensu stricto (s.s), E. multilocularis and E. shiquicus are commonly found co-endemic on the Qinghai-Tibet plateau, China, and an efficient tool is needed to facilitate the detection of infected hosts and for species identification. Methodology/Principal Findings A single-tube multiplex PCR assay was established to differentiate the Echinococcus species responsible for infections in intermediate and definitive hosts. Primers specific for E. granulosus, E. multilocularis and E. shiquicus were designed based on sequences of the mitochondrial NADH dehydrogenase subunit 1 (nad1), NADH dehydrogenase subunit 5 (nad5) and cytochrome c oxidase subunit 1 (cox1) genes, respectively. This multiplex PCR accurately detected Echinococcus DNA without generating nonspecific reaction products. PCR products were of the expected sizes of 219 (nad1), 584 (nad5) and 471 (cox1) bp. Furthermore, the multiplex PCR enabled diagnosis of multiple infections using DNA of protoscoleces and copro-DNA extracted from fecal samples of canine hosts. Specificity of the multiplex PCR was 100% when evaluated using DNA isolated from other cestodes. Sensitivity thresholds were determined for DNA from protoscoleces and from worm eggs, and were calculated as 20 pg of DNA for E. granulosus and E. shiquicus, 10 pg of DNA for E. multilocularis, 2 eggs for E. granulosus, and 1 egg for E. multilocularis. Positive results with copro-DNA could be obtained at day 17 and day 26 after experimental infection of dogs with larval E. multilocularis and E. granulosus, respectively. Conclusions/Significance The multiplex PCR developed in this study is an efficient tool for discriminating E. granulosus, E. multilocularis and E. shiquicus from each other and from other taeniid cestodes. It can be used for the detection of canids infected with E. granulosus s.s. and E. multilocularis using feces collected from these definitive hosts. It can also be used for the identification

Cattle in two herds developed signs of bloating, increased salivation and lacrimation, depression, respiratory distress, ataxia, and death after ingestion of hay that contained large amounts of poison hemlock (Conium maculatum). Twenty of 30 Angus cows and calves were affected in the first herd (2 died). In the second herd, 5 of 30 Holstein heifers were affected (1 died). The Conium alkaloids, coniine and gamma-coniceine, were quantified in the hay, the plants from the responsible hayfield, and the urine of affected animals.

Full Text Available Trabajo infantil e inasistencia escolar El capitalismo neoliberal ha generalizado la pobreza que obliga a muchas familias a recurrir al trabajo de los hijos para poder subsistir. Por el trabajo, los menores desertan de la escuela. Cuando adultos, por la pérdida en educación, sólo podrán acceder a las ocupaciones de menor calificación y peor pagadas. Por ello, tienen muchas probabilidades de ser los futuros padres de nuevos niños trabajadores reproduciendo intergeneracionalmente la pobreza. La educación es el primer paso para romper el círculo de la pobreza; hay relación entre los niveles de educación y las remuneraciones que las ersonas pueden alcanzar. El desarrollo descansa en el acelerado cambio tecnológico que no es más que el conocimiento científico aplicado a la producción. Crear conocimiento supone educación superior, y en la base de ésta está la educación básica, que es el cimiento de cualquier modelo de desarrollo que aspire a la equidad. No educar a los menores significa desperdiciar la formación de capital humano, ello traba el desarrollo nacional. Sin educación no habrá capital humano calificado como motor básico de la productividad y la competitividad.

Seasonal allergic rhinitis (hay fever) is common and can considerably reduce the quality of life of sufferers. Despite the wide everyday application and promising results with homeopathy, scientific evidence of its effectiveness for most ailments is scarce. The assessment of the clinical effectiveness of homeopathic remedies in the alleviation of hay fever symptoms in a typical clinical setting. We performed a clinical observational study of eight patients in the treatment of hay fever symptoms over a two-year period (2012 and 2013) using Measure Yourself Medical Outcome Profile (MYMOP) self-evaluation questionnaires at baseline and again after two weeks and four weeks of homeopathic treatment. The individualized prescription - either a single remedy or multiple remedies - was based on the totality of each patient's symptoms. The average MYMOP scores for the eyes, nose, activity and wellbeing had improved significantly after two and four weeks of homeopathic treatment. The overall average MYMOP profile score at baseline was 3.83 (standard deviation, SD, 0.78). After 14 and 28 days of treatment the average score had fallen to 1.14 (SD, 0.36; PHomeopathy.

The complete tree level cross-section for the process e + e - → e - ν-bar e ud-bar is computed using the GRACE system, a program package for automatic amplitude calculation. Special attention is brought to the gauge violation problem induced by the finite width of the W-boson. The preserved gauge scheme is introduced and an event generator including double-resonant, single-resonant and non-resonant diagrams with no need for a cut on the electron polar angle is built. A mono jet event rate estimation based on this process at LEP-I energy is discussed. (author). 11 refs., 9 figs
Intermittency in e+e- and lepton-hadron collisions

Sugano, K.

1990-01-01

The intermittency data in e + e - and lepton-hadron collisions are reviewed. The power-law behavior of the moments has been established by various e + e - experiments and a μp experiment. The intermittency in the two-dimensional space of rapidity and azimuthal angle is much stronger than in the rapidity space only. The neutrino-nucleus data indicate significant effects from nuclear reinteractions. The LUND parton shower model fits the data better than the matrix element model without special retuning. The relations among the moments of different orders are in good agreement with the predictions by the negative binomial and pure birth distributions. The origin of the intermittency in e + e - and μp collisions is consistent with the self-similar cascade mechanism of jet formation. 11 refs., 7 figs

The rumen microbiota enable important metabolic functions to the host cattle. Feeding of starch-rich concentrate feedstuffs to cattle has been demonstrated to increase the risk of metabolic disorders and to significantly alter the rumen microbiome. Thus, alternative feeding strategies like the use of high-quality hay, rich in sugars, as an alternative energy source need to be explored. The aim of this study was to investigate changes in rumen microbial abundances in the liquid and solid-associated fraction of cattle fed two hay qualities differing in sugar content with graded amounts of starchy concentrate feeds using Illumina MiSeq sequencing and quantitative polymerase chain reaction. Operational taxonomic units clustered separately between the liquid and the solid-associated fraction. Phyla in the liquid fraction were identified as mainly Firmicutes, Proteobacteria and Bacteroidetes, whereas main phyla of the fibre-associated fraction were Bacteroidetes, Fibrobacteres and Firmicutes. Significant alterations in the rumen bacterial communities at all taxonomic levels as a result of changing the hay quality and concentrate proportions were observed. Several intermicrobial correlations were found. Genera Ruminobacter and Fibrobacter were significantly suppressed by feeding sugar-rich hay, whereas others such as Selenomonas and Prevotella proliferated. This study extends the knowledge about diet-induced changes in ruminal microbiome of cattle. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

Bitumen on Water: Charred Hay as a PFD (Petroleum Flotation Device

Full Text Available Global demand for petroleum keeps increasing while traditional supplies decline. One alternative to the use of conventional crude oils is the utilization of Canadian bitumen. Raw bitumen is a dense, viscous, semi-liquid that is diluted with lighter crude oil to permit its transport through pipelines to terminals where it can then be shipped to global markets. When spilled, it naturally weathers to its original form and becomes dense enough to sink in aquatic systems. This severely limits oil spill recovery and remediation options. Here we report on the application of charred hay as a method for modifying the surface behavior of bitumen in aquatic environments. Waste or surplus hay is abundant in North America. Its surface can easily be modified through charring and/or chemical treatment. We have characterized the modified and charred hay using solid-state NMR, contact angle measurements and infrared spectroscopy. Tests of these materials to treat spilled bitumen in model aquatic systems have been undertaken. Our results indicate that bitumen spills on water will retain their buoyancy for longer periods after treatment with charred hay, or charred hay coated with calcium oxide, improving recovery options.
Heavy lepton production in e+e- annihilation

Kawamoto, Noboru

1976-01-01

We first enumerate several global properties of e + e - annihilation, which were left untouched in previous studies, as evidences of a heavy lepton with the mass of 1.8 GeV. As for the charged energy fraction in e + e - annihilation, we note that the effect of heavy lepton productions superimposed on the linearly decreasing background parametrized as r sub(h)=-0.014√s+0.632 can give a satisfactory fit to the data up to √s -- 8 GeV (where √s is the total c.m. energy). In this case, the charged energy fraction at PEP and PETRA energies is expected to come far below the naive application of the Llewellyn-Smith-Pais lower bound. We also compare the heavy lepton interpretation of the eμ events with other interpretations, and we argue that the 1.8 GeV heavy lepton gives the most plausible interpretation. Finally we discuss the observed eμ cross section and momentum distributions in terms of this heavy lepton with a general structure of the weak current and with an arbitrary mass for the associated neutrino.

Inclusive e{sup +}e{sup -} pair production in pp collisions at 2.2 GeV; Inklusive e{sup +}e{sup -}-Paarproduktion in pp-Reaktionen bei E{sub kin}=2.2 GeV

The work presented reports on the inclusive measurement of e{sup +}e{sup -} pairs in pp collisions at a beam energy of E{sub kin}=2.2 GeV using the HADES spectrometer. HADES focuses on the measurement of e{sup +}e{sup -} pairs which are an appropriate probe to study properties of hadronic matter in heavy ion collisions. Utilizing well-known sources, the inclusive analysis of the e{sup +}e{sup -} pair signal from pp collisions gives deeper insight in the understanding of the properties of the detector system. On the other hand vaguely known additional sources are for the first time accessible with a higher precision, which is important for the later understanding of heavy ion data. One main part of the work was to perform large Monte Carlo simulations that provided a reference data sample for comparison in each analysis step. The first step was the calculation of production cross sections for resonance states which are needed as an input for the event generator Pluto++. The events produced have then been propagated through a full-scale GEANT-based detector simulation to create a realistic detector response. This work puts effort on the correct treatment of particularities of the spectrometer set-up in the pp experiment. The single particle background was strongly reduced by applying special cuts to remove electrons and positrons that originate from {gamma}-conversion. This resulted in an overall signal-to-background-ratio (S)/(B){approx}4.7, while the invariant mass region above the {pi}{sup 0} mass - which is dominated by the {eta} Dalitz decay ({eta}{yields}e{sup +}e{sup -}) still has (S)/(B){approx}2.0. The remaining pair background has been calculated using a statistical analysis of like-sign pair distributions (e{sup +}e{sup +} and e{sup -}e{sup -}) as well as uncorrelated e{sup +}e{sup -} pairs from event mixing. The remaining signal contains 2020{+-}53 e{sup +}e{sup -} pairs and is dominated by the two dalitz decays {pi}{sup 0}{yields}{gamma}e{sup +}e
Spectrometer requirements for (e,e'2N) studies

One specific experiment that may be performed with a future CW accelerator is a study of (e,e'2N) reactions through which we may learn details of the short range interaction of two nucleons within nuclear matter. It is suspected that the only mechanism which can lead to the observed high momentum components in the single nucleon momentum distribution (above approx. 400 MeV/c) inferred from (e,e'p) and (γ,p) measurements is the presence of short-range few-body correlations in the many-body nuclear wave function. It is expected that the explicit pair correlation function may be inferred from relative two-nucleon momentum distributions measured in (e,e'2N) experiments. It is therefore interesting to estimate counting rates using measured one-body momentum distributions to see what types of spectrometers are required

Colour connections in e+e- annihilation

Friberg, C.; Gustafson, G.; Haekkinen, J.

We have very limited knowledge about how the confinement mechanism works in processes like e + e - →qqg..g, when there are identical colour charges. In this case the partons can be colour connected by a string or a cluster chain in several different ways. We do not know if in such a situation Nature chooses a particular configuration at random, or if some configuration is dynamically favoured. Also in the perturbative parton cascade we have no well-founded recipe for describing the interference effects, which correspond to non-planar diagrams and are caused by identical colour charges. We have studied two different models, and are in particular interested in the possibility that a colour singlet gluon system hadronizes isolated from the remainder of the state. Using double tagged events with heavy cc or bb quarks, it appears to be possible to find a significant signal, if such events appear in Nature. If this type of (re)connected states appear in Z decays it may also be an indication that reconnection might appear between the decay products of two W's in the reaction e + e - →W + W - →q 1 q 2 Q 1 Q 2 at LEP2. This would be important, e.g. for a precision measurement of the W mass. (orig.)

Full Text Available As características das leguminosas e gramíneas usadas como plantas de cobertura são bastante conhecidas, mas a velocidade com que os nutrientes associados à biomassa vegetal tornam-se disponíveis às culturas é ainda pouco estudada. O objetivo deste trabalho foi determinar o acúmulo e a taxa de liberação de nutrientes de crotalária e milheto solteiros ou consorciados. O delineamento experimental adotado foi blocos ao acaso, com quatro repetições. Os tratamentos foram crotalária, milheto, crotalária + milheto e vegetação espontânea. O acúmulo de P e Mg foi influenciado pela produção de massa, com valores elevados na crotalária, enquanto o acúmulo de Ca resultou tanto do maior teor quanto da maior produção de massa nos tratamentos com a leguminosa. A liberação de nutrientes dos resíduos apresentou dinâmica semelhante, com duas fases distintas: a primeira com taxas mais elevadas nos primeiros 15 dias e a segunda mais lenta a partir dessa fase. As taxas de liberação de K, Ca e Mg foram semelhantes, independentemente dos tratamentos. Os resíduos da crotalária apresentaram maior liberação de P do que as da vegetação espontânea, com meia vida de 11 dias e a vegetação espontânea de 17 dias. O Ca foi liberado mais lentamente do que os demais nutrientes, e o Mg mais rapidamente. As plantas espontâneas e o milheto apresentam importante potencial na reciclagem de K, e a crotalária se destacou na reciclagem de Ca e Mg.

Absolute, differential 4 He(e,e'p), (e,e'pp), and (e,e'dp) cross-sections in extended kinematical regions which are corresponding to the 'dip' between the quasielastic and the Δ-resonance peak in the 4 He(e,e') response-function have been measured at the high duty factor Electron Stretcher Accelerator ELSA of Bonn University. The scattered electrons were detected with a magnetic spectrometre, the hadrons with two sets of large-area plastic-scintillator telescopes. The measured cross-sections indicate important contributions from reactions on correlated nuclear pairs. In the 4 H(e,e'p) cross-sections the two-body break-up, 4 He(e,e'p)t, and the quasifree production of pions are visible as well. On the assumption of the Impulse-Approximation momentum-density distribution of the proton in 4 He have been derived from the measured cross-sections of the two-body and of the continuum break-up of the 4 He nucleus.

By using a survey design, data was collected from a convenience sample of customers of a major Kenyan commercial bank, and analysed using structural equation and multiple regression modelling. The findings reveal that there is a positive relationship between e-CRM and e-customers’ loyalty. The e-CRM features at all three stages of an electronic transaction cycle namely, pre-service, during-service and after-service, significantly influence the e-customers’ loyalty in the banking sector. Thus, to capitalize on the range of benefits that emanate from the use of e-CRM, continued review and enhancement of marketing strategies is needed, so as to achieve e-customers’ loyalty particularly, at the post-service stage. Kenyan commercial bank managers should focus on customer satisfaction specifically at post-service stage, to increase their ecustomers’ loyalty.

Turkey has successfully implemented the e-government project and with sub-projects such as the National Judiciary Information System Turkey received many international awards. Other than public services similar to e-hospital, e-municipality and e-tender, other social service institutions can also use same administrative approach as to make their service available. Therefore, this article shortly analyzes technical and legal challenges and technical, administrative and legal solutions of the e-Government portal.

The study of triple and quartic gauge boson vertices will be the centerpiece of experimental W boson physics at the next generation e + e - linear collider. We examine the sensitivity of a √ bar s = 500 GeV e + e - linear collider to anomalous structure in the W + W - γ and W + W - Z vertices. These vertices are tested by observing the reactions e - γ → νW - , γγ → W + W - , and e +- → W + W - . We also look at W + W - rescattering in e + e - → W + W - as a means to study W + W - → W + W -

Grasslands are often abandoned due to lack of profitability. Extensively cultivating grassland for utilization in a biogas-based biorefinery concept could mend this problem. Efficient bioconversion of this lignocellulosic biomass requires a pretreatment step. In this study the effect of different steam explosion conditions on hay digestibility have been investigated. Increasing severity in the pretreatment induced degradation of the hemicellulose, which at the same time led to the production of inhibitors and formation of pseudo-lignin. Enzymatic hydrolysis showed that the maximum glucose yields were obtained under pretreatment at 220 °C for 15 min, while higher xylose yields were obtained at 175 °C for 10 min. Pretreatment of hay by steam explosion enhanced 15.9% the methane yield in comparison to the untreated hay. Results indicate that hay can be effectively converted to methane after steam explosion pretreatment. Copyright © 2014 Elsevier Ltd. All rights reserved.
ePIANNO: ePIgenomics ANNOtation tool.

Full Text Available Recently, with the development of next generation sequencing (NGS, the combination of chromatin immunoprecipitation (ChIP and NGS, namely ChIP-seq, has become a powerful technique to capture potential genomic binding sites of regulatory factors, histone modifications and chromatin accessible regions. For most researchers, additional information including genomic variations on the TF binding site, allele frequency of variation between different populations, variation associated disease, and other neighbour TF binding sites are essential to generate a proper hypothesis or a meaningful conclusion. Many ChIP-seq datasets had been deposited on the public domain to help researchers make new discoveries. However, researches are often intimidated by the complexity of data structure and largeness of data volume. Such information would be more useful if they could be combined or downloaded with ChIP-seq data. To meet such demands, we built a webtool: ePIgenomic ANNOtation tool (ePIANNO, http://epianno.stat.sinica.edu.tw/index.html. ePIANNO is a web server that combines SNP information of populations (1000 Genomes Project and gene-disease association information of GWAS (NHGRI with ChIP-seq (hmChIP, ENCODE, and ROADMAP epigenomics data. ePIANNO has a user-friendly website interface allowing researchers to explore, navigate, and extract data quickly. We use two examples to demonstrate how users could use functions of ePIANNO webserver to explore useful information about TF related genomic variants. Users could use our query functions to search target regions, transcription factors, or annotations. ePIANNO may help users to generate hypothesis or explore potential biological functions for their studies.
Resonant e+e- production by time-varying electromagnetic field

Farakos, K.; Koutsoumbas, G.; Tiktopoulos, G.

1990-01-01

As pointed out by Cornwall and Tiktopoulos (CT) strong, time-varying electric fields may produce e + e - pairs in a resonant fashion. This effect could be related to the sharp peaks in the e + e - spectrum observed in the GSI heavy-ion collision experiments. We attempt to go beyond the case of spatially uniform fields discussed by CT. We find that resonant e + e - production indeed takes place for electric fields derived from four-potentials of the form A 1 =A 2 =A 0 =0, A 3 =δ(t)b(x 3 ) provided by b(x) has discontinuities with a jump at least equal to π.

In an Alpine environment, diets based on local forage resources are needed to maintain the link with the territory and confer special characteristics to typical cheeses. Harvesting at a late stage of maturity, high mechanical losses, and frequent rainfall often make the hay that is harvested of a poor quality. The aim of this study was to evaluate the effects of 2 different conservation methods (late hay, LH, vs. early haylage, ES) of natural permanent meadows on milk production in dairy cows, on the chemical and microbiological characteristics of the milk, and on the quality of the cheese over the winter period. Haylage and hay were harvested from the same permanent meadow at the Vittorino Vezzani experimental farm in Sauze d'Oulx (45 degrees 02'N, 6 degrees 53'E, Italy). The ES forage was cut 4 wk earlier than traditional hay, wilted for 30 h, baled at a dry matter (DM) content of about 50%, wrapped with 6 layers of stretch film, and stored in a protected area. The LH forage was harvested later, when the weather conditions were favorable and, after a 3-d wilting, it was baled and stored indoors. After an 8-mo storage period, the ES had a greater crude protein concentration, organic matter digestibility, and net energy for lactation than LH and a lower neutral detergent fiber and acid detergent fiber. Forty multiparous lactating Aosta Red Pied cows were used in a 19-d period crossover design to assess the nutritional value of the stored forages. The diets included ES fed ad libitum and 3.5 kg of DM per cow of concentrate or LH fed ad libitum and 5.1 kg of DM per cow of concentrate. The dietary DM was 90.1% for the LH and 59.9% for the ES. The diets contained 12.6 and 13.0% crude protein and 48.6 and 48.0% neutral detergent fiber, for the LH and ES, respectively. The forage intake was greater in the ES treatment than in the LH treatment. The ES treatment produced more milk (1.7 kg/d) and more 3.5% fat-corrected milk (1.5 kg/d) than the cows on the LH treatment. The

Bell, J A; Griinari, J M; Kennelly, J J

Conjugated linoleic acid (CLA) refers to a mixture of conjugated octadecadienoic acids of predominantly ruminant origin. The main isomer in bovine milk fat is the cis-9, trans-11 CLA. Interest in CLA increased after the discovery of its health-promoting properties, including potent anticarcinogenic activity. Two experiments were conducted to evaluate dietary strategies aimed at increasing the concentration of CLA in bovine milk fat. Both experiments were organized as a randomized complete block design with a repeated measures treatment structure. In Experiment 1, 28 Holstein cows received either a control diet or one of 3 treatments for a period of 2 wk. The control diet consisted of 60% forage (barley silage, alfalfa silage, and alfalfa hay) and 40% concentrate on a dry matter (DM) basis, fed as a total mixed ration (TMR). The concentrate was partially replaced in the treatment groups with 24 ppm of monensin (MON), 6% of DM safflower oil (SAFF), or 6% of DM safflower oil plus 24 ppm of monensin (SAFF/M). Average cis-9, trans-11 CLA levels in milk fat after 2 wk of feeding were 0.45, 0.52, 3.36, and 5.15% of total fatty acids for control, MON, SAFF, and SAFF/M, respectively. In Experiment 2, 62 Holstein cows received either a control diet or one of 5 treatment diets for a period of 9 wk. The control diet consisted of 60% forage (barley silage, alfalfa silage, and alfalfa hay) and 40% concentrate on a DM basis, fed as a TMR. The concentrate was partially replaced in the treatment groups with 6% of DM safflower oil (SAFF), 6% of DM safflower oil plus 150 IU of vitamin E/kg of DM (SAFF/E), 6% of DM safflower oil plus 24 ppm of monensin (SAFF/M), 6% of DM safflower oil plus 24 ppm of monensin plus 150 IU of vitamin E/kg of DM (SAFF/ME), or 6% of DM flaxseed oil plus 150 IU of vitamin E/kg of DM (FLAX/E). Average cis-9, trans-11 CLA levels during the treatment period were 0.68, 4.12, 3.48, 4.55, 4.75, and 2.80% of total fatty acids for control, SAFF, SAFF/E, SAFF

Full Text Available Electronic service (e-service via a web channel is one of the options that many companies use to provide service and support to customers. E-service is becoming increasingly important not only in determining the success or failure of electronic commerce, but also in providing consumers with a superior experience with respect to the interactive flow of information. The purpose of this paper is to review research and is to gather conceptual perspectives on the role and nature of e-service, and the e-service experience. Recent advances in technology have created a surge in technology-based self-service or e-service, and there is an increasing recognition of its role in differentiation and customer interfaces. In order to understand e-service experiences it is necessary to go beyond studies of e-service quality dimensions and to also take into account the inherent characteristics of e-service delivery and the factors that differentiate one service experience from another. The paper reviews the factors that impact on the nature of the e-service experience, taking a wider perspective than that adopted by many researcher on e-service when they focus on the identification of the dimensions of e-service quality. In order to manage the e-service experience it is important to develop a clear articulation of the nature, boundaries, components and elements of specific e-service experiences, and to further investigate the interaction between these factors and service quality dimensions.

The analysis uses data corresponding to 2 fb;{-1} of integrated luminosity of pp[over ] collisions at sqrt[s] = 1.96 TeV collected with the upgraded Collider Detector (CDF II) at the Fermilab Tevatron. The observed number of B0 and B_{s};{0} candidates is consistent with background expectations.

Physics of e+-e- colliders: present, future, and far future

International Nuclear Information System (INIS)

Peskin, M.E.

1984-10-01

The presentation of this lecture will proceed as follows: Section 2 reviews the features of e + -e - collisions according to the standard gauge theory of strong, weak, and electromagnetic interactions. This discussion reviews a few of the most important features of e + -e - collisions at currently accessible energies and the expectations for e + -e - reactions which produce the intermediate vector bosons Z 0 and W +- . Section 3 reviews some of the experimental work done at the current generation of e + -e - colliders; this discussion emphasizes the search for new types of elementary particles. Section 4 is a theoretical digression, introducing a number of ideas about physics at the energy scale of 1 TeV. Section 5 discusses (rather superficially) a number of technical aspects of electron-positron colliders designed to reach the TeV energies. Finally, Section 6 discusses various possible effects which could appear in e + -e - collisions as the result of new physics appearing at 1 TeV or above. 41 refs., 35 figs

The predicted decay spectra are compared with available experimental results. It is shown that the decay spectra are sensitive to multipole ad-mixtures of the excited state and can be used to study such admixtures. The available experimental data for the decay of the E2 resonances in 208 Pb contain spurious peaks that do not belong to the spectrum of 207 Pb. Theuuncertainty of the experimental data make it impossible to decide whether the decay is purely E2 or a mixture of 80% E2 plus 20% E6. (author) [pt

The growing usage of internet and online shopping in Malaysia presents a huge prospect in e-commerce market, specifically for B2C segment. As a result, electronic service quality (e-SQ), electronic satisfaction (e-Satisfaction) and electronic loyalty (e-Loyalty) become vital for online retailers to attract and retain online shoppers in this virtual environment. The association between e-SQ, e-Satisfaction and e-Loyalty should be continuously examined to cope with the advancement in information and communication technology, and the changing expectation of online shoppers. However, construct of e-SQ for online retailers in B2C market is still debatable. In this research, E-SERVQUAL was integrated with the other e-SQ scales to measure e-SQ of a prominent online retailer in Malaysia. Specifically, the e-SQ constructs are Efficiency, Privacy and Trust, Fulfilment, Responsiveness, Contact and Website Design. 390 sets of completed and usable questionnaires were gathered using online questionnaire and convenience sampling procedure. The result indicated that the five proposed dimensions of e-SQ constitute e-SQ of online retailer in B2C market. All the dimensions of e-SQ were found to have positive and significant effect on e-Satisfaction of online shoppers. Responsiveness of e-SQ had the strongest impact on e-satisfaction of online shoppers. The shoppers e-Satisfaction was positively and significantly affected their e-Loyalty towards continuous usage of online retailer's website. Managerial and theoretical implications are discussed based on the results of the study.

Background to neutrino counting in e+e- collisions

International Nuclear Information System (INIS)

Dicus, D.A.

1979-06-01

The background from e + e - → 3γ to the proposed neutrino counting process of e + e - → γ ν anti ν is calculated. It is shown that at PEP or PETRA beam energies the 3γ cross section is at least three orders of magnitude greater than the γ ν anti ν cross section. At higher beam energies, near the Z pole, the γ ν anti ν cross section is larger than the background but other ambiguities may make a determination of the number of types of neutrinos very difficult. 9 references
PLUTO collaboration: e+e- interactions at PETRA

The University of Maryland HEP Group has been involved with the PLUTO collaboration investigating e + e - interactions at PETRA since 1977. For the final data taking period the PLUTO detector was modified to include small angle spectrometers to make it sensitive to particles produced at small angles in γγ interactions. Data was taken in this configuration from September of 1981 to July of 1982. The integrated luminosity for this period was about the integral of Ldt = 50 pb -1 . That was the last data taking period for PLUTO and many of the collaborators have joined other PETRA experiments. Data analysis has continued since that time, culminating in many publications in 1984, especially in the area of two photon interactions via the process e + e - → e + e - + γγ → X, where X can consist of hadrons or leptons. The major data analysis effort of the collaboration was spent in understanding the interaction γγ → hadrons. The work was carried out from these different points of view: total cross sections as a function of the center of mass energy of the γγ system, the photon structure function as a function of Q 2 and the Bjorken scaling variable X, and the topological properties of final state hadrons, especially as to whether high transverse momenta particle jets can be observed

Seiberg duality and e+e- experiments

De Gouvea, Andre; Friedland, Alexander; Murayama, Hitoshi

Seiberg duality in supersymmetric gauge theories is the claim that two different theories describe the same physics in the infrared limit. However, one cannot easily work out physical quantities in strongly coupled theories and hence it has been difficult to compare the physics of the electric and magnetic theories. In order to gain more insight into the equivalence of two theories, we study the ''e + e - '' cross sections into ''hadrons'' for both theories in the superconformal window. We describe a technique which allows us to compute the cross sections exactly in the infrared limit. They are indeed equal in the low-energy limit and the equality is guaranteed because of the anomaly matching condition. The ultraviolet behavior of the total ''e + e - '' cross section is different for the two theories. We comment on proposed nonsupersymmetric dualities. We also analyze the agreement of the ''γγ'' and ''WW'' scattering amplitudes in both theories, and in particular try to understand if their equivalence can be explained by the anomaly matching condition

We examined the impact of e-cigarette advertising on e-cigarette use behaviors among youth over time. At baseline, 3907 students participated in a youth tobacco surveillance study from 2014-2015 and 2488 students completed a 6-month follow-up. Weighted logistic regression models investigated the recall of e-cigarette advertisements (TV/radio/billboards/retail/Internet) as a risk factor for e-cigarette perceived harm, use, and susceptibility. The odds of ever e-cigarette use was 3 times higher (AOR=2.99; 95% CI, 1.50-5.97) at 6-month follow-up among e-cigarette never-users who recalled e-cigarette advertisements in retail stores at baseline, compared to those who did not. Likewise, the odds of current e-cigarette use and susceptibility to e-cigarette use at 6-month follow-up were 2.03 (95% CI, 1.11-3.72) and 1.77 (95% CI, 1.20-2.61), respectively. Additionally, recall of e-cigarette advertisements on the Internet at baseline was significantly related to current use (AOR=2.17; 95% CI, 1.05-4.48) and susceptibility to use e-cigarettes (AOR=1.72;95% CI, 1.15-2.58) at 6-month follow-up. Recall of e-cigarette advertisements at point-of-sale and on the Internet was significantly associated with adolescent e-cigarette susceptibility and use, which supports the need to minimize adolescent exposure to these advertisements.

As revealed in a previous microarray study to identify genes regulated by 20-hydroxyecdysone (20E) and juvenile hormone (JH) in the silkworm, Bombyx mori, E93 expression in the fat body was markedly low prior to the wandering stage but abundant during larval-pupal metamorphosis. Induced by 20E and suppressed by JH, E93 expression follows this developmental profile in multiple silkworm alleles. The reduction of E93 expression by RNAi disrupted 20E signaling and the 20E-induced autophagy, caspase activity, and cell dissociation in the fat body. Reducing E93 expression also decreased the expression of the 20E-induced pupal-specific cuticle protein genes and prevented growth and differentiation of the wing discs. Importantly, the two HTH domains in E93 are critical for inducing the expression of a subset of 20E response genes, including EcR, USP, E74, Br-C, and Atg1. By contrast, the LLQHLL and PLDLSAK motifs in E93 inhibit its transcriptional activity. E93 binds to the EcR-USP complex via a physical association with USP through its LLQHLL motif; and this association is enhanced by 20E-induced EcR-USP interaction, which attenuates the transcriptional activity of E93. E93 acts through the two HTH domains to bind to GAGA-containing motifs present in the Atg1 promoter region for inducing gene expression. In conclusion, E93 transcriptionally modulates 20E signaling to promote Bombyx larval-pupal metamorphosis. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

An influence of an additional neutral Z' bozon on characteristics of e - e + →ff-bar processes is studied, where ff-bar is a pair of arbitrary particles (leptons, nucleons, hyperons, pseudoscalar or vector mesons etc.). The general expression for the differential cross sections of e - e + →ff-bar processes is obtained with arbitrary polarizations of an electron-positron pair by introducing of structure functions, and the following integral characteristics are considered: polarized forward A F (λ 2 ) and backward A B (λ 2 ) assymmetries; right-left asymmetry A RL ; forward-backward asymmetry in the case of longitudinal polarized e - e + pair annihilation A BH (λ 2 ); transversal spin assymmetries A Φ (1) and A Φ (2) ; the degree of longitudinal polarization of r lepton P in e - e + → r - r + r - r + process. The general expressions for these characteristics are found and their quantitative estimates are given in the framework of superstring E 6 -model. 20 refs.; 5 figs.; 2 tabs
Generation-changing interaction of sneutrinos in e+e- collisions

Oshimo, N.

2004-01-01

The measurability of generation mixing is studied on pair production of sneutrinos in e + e - collisions and their subsequent decays into two different charged leptons e and μ with two lighter charginos. The analyses are made systematically in a general framework of the supersymmetric extension of the standard model. The production and decay process depends on the parameters of the chargino sector as well as those of the sneutrino sector. Although generation-changing interactions are severely constrained by radiative charged-lepton decays, sizable regions in the parameter space could still be explored at e + e - colliders in the near future.

The banning of sales of nicotine e-liquid in e-cigarette shops has been implemented in several states in Malaysia. The distribution of nicotine e-liquid can only be allowed by licensed pharmacies or registered medical practitioners. This study aimed to evaluate e-cigarette users' responses to the control policy in a cross-sectional survey of 851 e-cigarette users by utilizing a self-report questionnaire that assessed (1) attitudes on regulation policy of e-cigarette banning; (2) e-cigarette use behaviors; and (3) sources of e-liquid after the regulation policy has been implemented. Participants from the state of Selangor where the banning policy was implemented were surveyed. The majority (95.8%) opposed the banning and believed e-cigarettes should be sold to anyone aged 18 years or above as with tobacco cigarettes, only a minority believed that nicotine e-liquid should only be available for sale over the counter in pharmacy stores (14.6%) and in clinics with a doctor's prescription (11.8%). The majority (44.2%) reported that they would continue their e-cigarette use as before the banning policy, while 20% plan to completely stop e-cigarette usage without replacing it with any alternatives. The vast majority (87.9%) was still able to obtained nicotine e-liquid from e-cigarette shops in spite of the ban and the second most common source was from online purchase (63.1%). The sales of nicotine e-liquid from black-market were evidenced as many reported obtaining zero nicotine e-liquid from the black market (54.4%). Self- or home-made (30.8%) nicotine e-liquid was also reported. Majority of respondents that self-made e-liquid were from the average monthly income group (below MYR3000). Obtaining nicotine from the pharmacy was least preferred (21.4%). Provision of professional advice to nicotine e-liquid users along with the ban may lessen the likelihood of users switching to tobacco cigarettes or other nicotine alternatives.

Questa convergenza tra l’architettura testuale del fiabesco e le strutture cognitive può, almeno in parte, spiegare il carattere di universalità del genere e la sua diffusione come dispositivo mnemonico, in grado di convogliare significati individuali e collettivi, e come ‘microsceneggiatura’ utile per agire nel mondo reale.
Famílias homoparentais e escola: reflexões e possibilidades

Full Text Available As normas hegemônicas heterossexistas presentes na sociedade privilegiam relações e comportamentos que as ratifiquem e consequentemente, crenças e valores que as fortaleçam. Desta forma, as configurações familiares que não condizem com o modelo heterossexual, como a família homoparental, são desfavorecidas nas relações sociais, legislação e políticas públicas. Diante deste cenário, o objetivo deste trabalho é refletir, a partir de publicações na área de educação sexual, diversidade e homoparentalidade, de que forma mitos relacionados à homossexualidade e conceitos de família podem interferir na forma como a escola lida com a homoparentalidade. Algumas crenças distorcidas influenciam a visão social sobre a homoparentalidade como: a pessoas de orientação sexual homossexual seriam promíscuas e não proporcionariam um ambiente adequado ao desenvolvimento sadio de uma criança; b pessoas de orientação sexual homossexual sofreriam de algum tipo de desvio ou distúrbio e por isso não deveriam cuidar de uma criança; c crianças que convivem com pais/mães homossexuais sofreriam muito preconceito o que prejudicaria seu desenvolvimento e adaptação social, obrigatoriamente; d a criança perderia a noção de diferença entre os gêneros e isso afetaria seu desenvolvimento e convívio social; e a criança tenderia a ser homossexual também; f a criança interpretaria a relação homossexual como adequada, o que poderia prejudicar seu desenvolvimento e convívio social. A escola, como instituição inserida na sociedade, e os profissionais que nela atuam, encontram-se submersos nestas crenças distorcidas, tendo também suas práticas influenciadas. Estudos mostram que grande parte dos profissionais da área da educação não conta com formação inicial ou continuada que aborde de forma crítica e reflexiva temas sobre sexualidade ou diversidade familiar.

Twenty animals, ten sheep and ten goats were allocated in a randomized block design, with two treatments and two species: PEG group (supplemented with 10 g of PEG and control group (without supplementation. Significant differences were not observed between treatments and species regarding the intake and digestibility of dry matter and neutral detergent fiber. Nevertheless, PEG supplementation enhanced the crude protein digestibility of Sabiá shrub hay from 33.96% to 38.74% in sheep and from 43.29% to 54.41% in goats, showing that the supplementation with PEG could become a good feeding strategy against the antinutritional effects of tannin of the forage plants.

The primary objective of this pilot study was to describe the impact of e-cigarette liquid flavors on experienced e-cigarette users' vaping behavior. 11 males and 3 females participated in a 3-day inpatient crossover study using e-cigarettes with strawberry, tobacco, and their usual brand e-liquid. Nicotine levels were nominally 18 mg/mL in the strawberry and tobacco e-liquids and ranged between 3-18 mg/mL in the usual brands. On each day, participants had access to the study e-cigarette (KangerTech mini ProTank 3, 1.5 Ohms, 3.7 V) and the assigned e-liquid during a 90-minute videotaped ad libitum session. Average puff duration was significantly longer when using the strawberry e-liquid (3.2 ± 1.3 s, mean ± SD) compared to the tobacco e-liquid (2.8 ± 1.1 s) but the average number of puffs was not significantly different (strawberry, 73 ± 35; tobacco, 69 ± 46). Compared to the strawberry- and tobacco-flavored e-liquids, average puff duration was significantly longer (4.3 ± 1.6 s) and the average number of puffs was significantly higher (106 ± 67 puffs) when participants used their usual brand of e-liquid. Participants generally puffed more frequently in small groups of puffs (1-5 puffs) with the strawberry compared to the tobacco e-liquid and more frequently in larger groups (>10 puffs) with their usual brand. The strength of the relationship between vaping topography and nicotine intake and exposure were not consistent across e-liquids. Vaping behavior changes across e-liquids and influences nicotine intake. Research is needed to understand the mechanisms that underlie these behavioral changes, including e-liquid pH and related sensory effects, subjective liking, and nicotine effects. Copyright © 2018.

Cascades from nu_E above 1020 eV

Energy Technology Data Exchange (ETDEWEB)

Klein, Spencer R.

2004-12-21

At very high energies, the Landau-Pomeranchuk-Migdal effect reduces the cross sections for electron bremsstrahlung and photon e{sup +}e{sup -} pair production. The fractional electron energy loss and pair production cross sections drop as the energy increases. In contrast, the cross sections for photonuclear interactions grow with energy. In solids and liquids, at energies above 10{sup 20} eV, photonuclear reactions dominate, and showers that originate as photons or electrons quickly become hadronic showers. These electron-initiated hadronic showers are much shorter (due to the absence of the LPM effect), but wider than purely electromagnetic showers would be. This change in shape alters the spectrum of the electromagnetic and acoustic radiation emitted from the shower. These alterations have important implications for existing and planned searches for radiation from u{sub e} induced showers above 10{sup 20} eV, and some existing limits should be reevaluated.

Antropologia e filosofia: estética e experiência em Clifford Geertz e Walter Benjamin

Full Text Available Este artigo estuda as concepções de estética e experiência de Clifford Geertz e Walter Benjamin como possibilidades argumentativas e metodológicas para pensar a realidade e suas formas estéticas. Utiliza-se para isso as discussões metodológicas de Geertz, especialmente a respeito do lugar da estética e de sua relação com os demais âmbitos do humano, que encetaram uma nova forma de concebê-los para a etnografia e antropologia de modo geral, e os estudos de Benjamin a respeito da estética como expressão fisionômica de uma época, de determinada realidade, especialmente os que se referem sobre a modernidade. Constata-se essa possibilidade a partir da observação de que a estética e a experiência, nos autores, são tomadas como dimensões da realidade que se relacionam, não de modo mecânico, e sim como âmbitos que atravessam a realidade, os artefatos estéticos, os discursos, e esses assim devem ser observados.This article study the conceptions of aesthetics and experience of Clifford Geertz and Walter Benjamin as argumentative and methodological possibilities for thinking reality and its aesthetic forms. Uses for this Geertz's methodological discussions, especially regarding the place of aesthetics and its relation to other spheres of the human, which has embarked on a new way of conceiving them to ethnography and anthropology in general, and studies Benjamin about the aesthetics and physiognomical expression of an era, a certain reality, especially those concerning about modernity. There is that possibility from the observation that the aesthetics and experience, in the authors, are taken as the dimensions of reality are related, not mechanically, but as areas that cross the reality, the aesthetic artifacts, the speeches, and so these must be observed.

The current paper applied the Theory of Planned Behavior (TPB; Ajzen & Fishbein, 1988) to understand how impulsive personality traits and attitudes concerning e-cig use relate to the likelihood of electronic cigarette (e-cig) use. Seven hundred and fourteen participants (Mean age = 34.04, SD = 10.89, 48.6% female) completed cross-sectional measures of e-cig use attitudes (CEAC) and the Short UPPS-P Impulsive Behavior Scale. A structural path analysis suggested that urgency and deficits in conscientiousness were significantly related to e-cig attitudes (CFI = 0.99, TLI = 0.99, RMSEA = 0.02; urgency: β = 0.32, p = .001; deficits in conscientiousness: β = -0.48, p E-cig attitude scores were significantly higher for e-cig users than non-users, β = 0.85, p e-cig use. Findings provide initial support for a model in which impulsive traits are related to e-cig use through positive e-cig attitudes.

Effects of hay management and native species sowing on grassland community structure, biomass, and restoration.

Prairie hay meadows are important reservoirs of grassland biodiversity in the tallgrass prairie regions of the central United States and are the object of increasing attention for conservation and restoration. In addition, there is growing interest in the potential use of such low-input, high-diversity (LIHD) native grasslands for biofuel production. The uplands of eastern Kansas, USA, which prior to European settlement were dominated by tallgrass prairie, are currently utilized for intensive agriculture or exist in a state of abandonment from agriculture. The dominant grasslands in the region are currently high-input, low-diversity (HILD) hay fields seeded to introduced C3 hay grasses. We present results from a long-term experiment conducted in a recently abandoned HILD hay field in eastern Kansas to evaluate effects of fertilization, haying, and native species sowing on community dynamics, biomass, and potential for restoration to native LIHD hay meadow. Fertilized plots maintained dominance by introduced grasses, maintained low diversity, and were largely resistant to colonization throughout the study. Non-fertilized plots exhibited rapid successional turnover, increased diversity, and increased abundance of C4 grasses over time. Haying led to modest changes in species composition and lessened the negative impact of fertilization on diversity. In non-fertilized plots, sowing increased representation by native species and increased diversity, successional turnover, and biomass production. Our results support the shifting limitations hypothesis of community organization and highlight the importance of species pools and seed limitations in constraining successional turnover, community structure, and ecosystem productivity under conditions of low fertility. Our findings also indicate that several biological and functional aspects of LIHD hay meadows can be restored from abandoned HILD hay fields by ceasing fertilization and reintroducing native species through

This program generates events based on the standard model, i.e., quantum chromodynamics (QCD) and electro-weak theory. It works at the center-of-mass energy below W + W - production, i.e., in the energy region of TRISTAN, SLC and LEP. For these high energy machines one of the important subjects is the exploration for the top quark. The production and hadronization of the top quark is included in EPOCS. Besides the top quark, we expect 'new' physics in this high energy region. EPOCS has enough flexibility for users to cope with a new idea. Users can register a new particle, modify the built-in particle data, define new primary interactions and so on. The event generator has a number of parameters, both physical parameters and control parameters. Users can control most of these parameters in EPOCS at will. (author)

To test whether exposure and receptivity to e-cigarette marketing are associated with recent e-cigarette use among young adults through increased beliefs that e-cigarettes are less harmful than cigarettes. Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette smokers [mean age = 23.5 (SD = 5.5); 65% female]. Higher receptivity to e-cigarette marketing was associated with perceptions that e-cigarettes are less harmful than cigarettes, which in turn, were associated with higher recent e-cigarette use. The findings provide preliminary support to the proposition that marketing of e-cigarettes as safer alternatives to cigarettes or cessation aids is associated with increased e-cigarette use among young adults. The findings have implications for development of e-cigarette regulations.

Muscarella, Miriam; Kranenburg-van Koppen, Laura; Grijpink-van den Biggelaar, Kalinka; Drop, Stenvert L S

2014-01-01

The past 20 years have seen proliferation of electronic (e) resources that promote improved understanding of disorders of sex development (DSD): e-learning for physicians and trainees, e-consultation between clinicians, and e-information for families and affected individuals. Recent e-learning advances have emerged from the European Society for Pediatric Endocrinology's online learning portal for current physicians and trainees. Developed with attention to developing clinical competencies incorporating learning theory, and presenting material that represents international best practice, this e-learning portal offers advances in training, making information more accessible for clinicians and trainees. Multiple levels of instruction, authentic case examples, collaborative forums for physicians and trainees, individualized feedback and user-friendly tools represent advances in trainee and physician learning that can take place in any location. e-consultation is an emerging tool that aims to connect physicians with specialists experienced in DSD care. Although it faces logistical challenges, e-consultation carries the potential to improve DSD care, especially in remote areas with limited access to DSD specialists. e-information for families and patients of all ages is widely accessible online, often with focus on DSD biology, medical care, and psychological and social support. e-information tools aid self-management and support of those affected by DSD. Efforts to improve these resources should aim to map information to individual users, incorporate optimally clear nomenclature, and continue as a 'shared enterprise' of clinicians, affected individuals, families and researchers. Improving the quality of DSD-related e-learning and e-information and developing e-consultation carries the potential to transform DSD care and support for patients, families and physicians worldwide. © 2014 S.

The dimensionless quantity 1/sigmasub(tot) dsigma/dz, which is determined solely by the meson wave functions and is independent of all parameters of the theory, agrees well with the existing experimental data. We give also the inclusive distributions for PSI, D, F and a heavy quark mesons in high energy e + e - experiments. (orig.) [de
Narrazioni e genere

Full Text Available Gli studi di genere rappresentano un terreno particolarmente fecondo per l’approccio narrativo nelle sue diverse articolazioni. L’interesse nei confronti delle narrazioni è in realtà già un elemento centrale e distintivo della letteratura femminista e dei women’s studies, prima ancora che degli studi di genere, e all’interno di questi filoni di studio sono in effetti emersi alcuni rilevanti spunti per il dibattito sulla conoscenza narrativa. L’attenzione per le narrazioni da parte di questo filone di studi nasce probabilmente dalla critica che la letteratura femminista sviluppa nei confronti del sapere razionale e di modelli epistemologici fondati sul paradigma dell’oggettività, che tendono a cancellare la dimensione esperienzale. Le metodologie femministe si sono infatti ben presto caratterizzate per l’attenzione rivolta alla problematizzazione dei processi di conoscenza e di conduzione della ricerca scientifica, di cui viene messa in evidenza la dimensione di costruzione sociale e quindi anche il carattere inevitabilmente gendered. La pretesa di separare l’oggetto e il soggetto della ricerca è stata interpretata alla luce di quello stesso ordine dicotomico, che distingue tra pubblico e privato e tra maschile e femminile, e secondo il quale le esperienze personali non sono scientifiche, in quanto associate all’ambito del privato e quindi, storicamente, anche del femminile. Su tale fondamento si sarebbe di fatto sostenuta l’egemonia della maschilità nel dominio della scienza. Il ricorso alle narrazioni è stato in tal senso inteso come un’opportunità per riconciliare queste diverse dimensioni, stimolando il dinamismo della produzione di conoscenza e generando nuove visioni alternative, capaci di superare vecchi preconcetti e dicotomie.
Universitality features in (pp), (e+e-), and deep inelastic scattering process

International Nuclear Information System (INIS)

Zichichi, A.

1985-01-01

This paper discusses the use of the correct variables in (pp), (e + e - ), and deep-inelastic scattering (DIS) processes which allow universality features to be established different ways of producing mulihadronic states. The experimental data where (pp) interactions are compared with (e + e - ) are shown. Extrapolations of collider physics are discussed and it is found that the leading effects must be subtracted and the correct variables have to be used if one wants to compare purely hadronic interactions with (e + e - ) and DIS. The new method of studying (pp) and (pp) collisions allows one to put on equal footing the multiparticle systems that are produced in purely hadronic interactions, in (e + e - ) annihilation, and in DIS processes

We report results of an experiment to search for a resonance enhancement of the e + e- scattering cross section in a metallic Li target utilizing an energy-tunable monoenergetic positron beam. Within statistical uncertainties (0.27%) no evidence has been observed for deviations from Bhabha scattering over the entire invariant-mass region 1560 keV/c 2 X 0 2 that can be associated with the e + e- sum-peak energies in GSI heavy-ion experiments. Under the assumptions that the e + e- channel dominates, we deduce lower limits on lifetimes τ>3.3x10 -13 sec (J=0) and τ>8.2x10 -13 sec (J=1), at 90% C.L

E-Orbit Functions

2008-01-01

Full Text Available We review and further develop the theory of $E$-orbit functions. They are functions on the Euclidean space $E_n$ obtained from the multivariate exponential function by symmetrization by means of an even part $W_{e}$ of a Weyl group $W$, corresponding to a Coxeter-Dynkin diagram. Properties of such functions are described. They are closely related to symmetric and antisymmetric orbit functions which are received from exponential functions by symmetrization and antisymmetrization procedure by means of a Weyl group $W$. The $E$-orbit functions, determined by integral parameters, are invariant withrespect to even part $W^{aff}_{e}$ of the affine Weyl group corresponding to $W$. The $E$-orbit functions determine a symmetrized Fourier transform, where these functions serve as a kernel of the transform. They also determine a transform on a finite set of points of the fundamental domain $F^{e}$ of the group $W^{aff}_{e}$ (the discrete $E$-orbit function transform.

2015-11-01

The electronic cigarette (e-cigarette) market is maturing into a billion-dollar industry. Expansion includes new channels of access not sufficiently assessed, including Internet sales of e-cigarettes. This study identifies unique e-cigarette Internet vendor characteristics, including geographic location, promotional strategies, use of social networking, presence/absence of age verification, and consumer warning representation. We performed structured Internet search engine queries and used inclusion/exclusion criteria to identify e-cigarette vendors. We then conducted content analysis of characteristics of interest. Our examination yielded 57 e-cigarette Internet vendors including 54.4% (n=31) that sold exclusively online. The vast majority of websites (96.5%, n=55) were located in the U.S. Vendors used a variety of sales promotion strategies to market e-cigarettes including 70.2% (n=40) that used more than one social network service (SNS) and 42.1% (n=24) that used more than one promotional sales strategies. Most vendors (68.4%, n=39) displayed one or more health warnings on their website, but often displayed them in smaller font or in their terms and conditions. Additionally, 35.1% (n=20) of vendors did not have any detectable age verification process. E-cigarette Internet vendors are actively engaged in various promotional activities to increase the appeal and presence of their products online. In the absence of FDA regulations specific to the Internet, the e-cigarette e-commerce marketplace is likely to grow. This digital environment poses unique challenges requiring targeted policy-making including robust online age verification, monitoring of SNS marketing, and greater scrutiny of certain forms of marketing promotional practices.

2002-01-01

Full Text Available Autores como Michel Foucault e Franz Fanon têm figurado de forma influente tanto em estudos sobre questões relativas a estratégias de poder e representação em contextos pós-coloniais, quanto em debates e análises de ordem teórica sobre pós-colonialismo. Particularmente, as noções de biopoder e governamentalidade, originárias do pensamento de Foucault, e as reflexões de Fanon sobre a construção de formas de subjetivação racializadas e coloniais, têm ensejado um amplo debate sobre a permanência e circulação de retóricas raciais transnacionais. Através da leitura de David Scott, em Refashioning Futures - Criticism after Postcoloniality (1999, e Paul Gilroy, em Against Race - Imagining Political Culture beyond the Color Line (2000, este ensaio procura identificar a pertinência da combinação de ambos os autores em estudos que, de forma distinta, se debruçam sobre a complexa relação entre corpo e modernidade e suas implicações nos campos político e intelectual contemporâneos.

Esse artigo descreve como jovens religiosos e autoridades religiosas de sua comunidade compreendem a sexualidade, considerando suas experiências pessoais e como membros de comunidades religiosas. A análise pretende contribuir para que políticas públicas dedicadas à promoção da saúde sexual da juventude considerem a religiosidade, no contexto de um estado laico e da promoção do direito à prevenção. Foram realizadas 26 entrevistas abertas e semidirigidas em diferentes comunidades da região metropolitana da cidade de São Paulo (comunidades católicas, da umbanda, do candomblé e de diferentes denominações evangélicas) sobre iniciação sexual, casamento, gravidez, contracepção e prevenção das DST/Aids, homossexualidade, aborto e direitos humanos. Observou-se como jovens e autoridades religiosas convivem com a tensão entre tradição e modernidade e os distintos discursos sobre a sexualidade. Como sujeitos religiosos (do discurso religioso) e sujeitos sexuais (de discursos sobre sexualidade), devem ser incorporados pelos programas como sujeitos de direito nos termos de sua religiosidade.

2010-01-01

The Environmental e-Health Research and Training Program has completed its scoping study to understand the breadth of a new field of research: Environmental e-Health. Nearly every aspect of modern life is associated, directly or indirectly, with application of technology, from a cup of coffee, through transportation to and from work, to appliances in the home and industrial activities. In recent decades the rapidly increasing application of information and communications technologies (ICT) has added to the cacophony of technological 'noise' around us. Research has shown that technology use, including ICTs, has impact upon the environment. Studying environmental impact in such a complex global setting is daunting. e-Health is now being used as a convenient microcosm of ICT application within which to study these impacts, and is particularly poignant given that e-Health's environmental harms conflict with its noble goals of 'doing no harm'. The study has identified impacts, both benefits and harms in all three life-cycle phases for e-Health: up-stream (materials extraction, manufacturing, packaging, distribution), mid-stream (use period), and down-stream (end-of-life processes--disposal, recycling). In addition the literature shows that a holistic 'Life Cycle Assessment' approach is essential to understand the complexity of the setting, and determine the true balance between total harms and total benefits, and for whom.

Waterway e sviluppo del territorio: nuova mobilità e turismo sostenibile

Full Text Available Spesso origine dei primi insediamenti urbani, i corsi d’acqua sono stati nei secoli fonte di sostentamento per le popolazioni e strumento di scambio tra genti e culture. Proprio per il loro scorrere attraverso il territorio, essi sono per definizione luoghi di relazione, di intersezione tra diverse realtà urbane dove si incontrano ambiente, architettura, pianificazione, trasporti ma anche arte, cultura e turismo. Per questa loro caratteristica, le vie d’acqua rappresentano una grande potenzialità per lo sviluppo del territorio sia in termini di mobilità – di merci e di persone - che di turismo sostenibile. La loro riqualificazione permette di recuperare il ruolo di spazio pubblico e di paesaggio rurale, urbano e turistico di qualità; luoghi di fruizione turistica, culturale, gastronomica e sportiva, quindi di qualità della vita. Dopo decenni di oblio, sollecitata dal rinnovato interesse verso questi assi e anche dalle direttive dell’Unione Europee, l’Italia e, in particolare il Nord del paese, muove i primi passi verso la valorizzazione delle waterway a fini turistico-culturali, aprendo nuove possibilità di sviluppo del territorio. Sia pur con ritardo rispetto ad altri Paesi, che da anni e in diverse forme valorizzano e “sfruttano” le vie d’acqua, si avverte anche in Italia un cambio di mentalità che vede nell’uso e nel recupero di tale risorsa uno strumento importante per garantire la sostenibilità ambientale ed economica e il recupero di una identità culturale quasi dimenticata.

Full Text Available A suplementação de fontes de amido de maior digestibilidade e o uso de aditivos com atividade coccidiostática e promotora de crescimento podem melhorar o desempenho de bezerros leiteiros pré e pós desmama. O objetivo deste trabalho foi avaliar o efeito de concentrados contendo milho laminado a vapor ou floculado, com ou sem a adição de monensina, no consumo, ganho de peso e parâmetros sanguíneos de bezerras leiteiras, antes e após a desmama realizada a sexta semana de vida. Foram utilizadas 32 bezerras holandesas do nascimento a 12 semanas de vida, em um delineamento experimental do tipo blocos ao acaso, com arranjo fatorial 2 x 2. Do nascimento à desmama os animais receberam concentrado ad libitum até o consumo de 2 kg/d, quatro litros diários de leite e tiveram acesso livre à água. Após a desmama, realizada na sexta semana de vida, os animais continuaram recebendo 2 kg de concentrado e passaram a ter acesso a feno picado ad libitum. O tipo de processamento de grão ou a adição de monensina não afetaram o consumo médio de concentrado ou feno, assim como o peso final e o ganho de peso diário. As concentrações plasmáticas de glicose e ácidos graxos livres (AGL médios do período experimental não foram afetadas pelos tratamentos; entretanto, as concentrações de n-uréico foram inferiores no plasma de animais recebendo concentrado com grãos laminados e monensina. Houve efeito da idade do animal nas concentrações plasmáticas de glicose, n-uréico e AGL. Somente os parâmetros glicose e AGL plasmáticos foram afetados pelo horário após o fornecimento do alimento. A inclusão de monensina ou de grão processados na dieta de bezerras leiteiras não resultou em melhor desempenho animal, antes ou após a desmama.The supplementation of more digestible starch sources and feed additives with coccidiostatic and growth promoting activities may improve pre and post weaning calves performance.

Arte e vida em Vigotski e o modernismo russo

Directory of Open Access Journals (Sweden)

Luana Maribele Wedekin

2013-12-01

Full Text Available Em sua obra "Psicologia da Arte" (concluída em 1925, L.S. Vigotski escreve sobre o tema arte e vida, dialogando com algumas das principais teorias estéticas de sua época. Objetiva-se neste estudo teórico contextualizar esses interlocutores e algumas das ideias desse autor, com a apresentação dos argumentos fundamentais sobre as relações entre arte e vida no embate entre as vertentes realistas e simbolistas do modernismo russo, especialmente na literatura e artes visuais. Conclui-se que a perspectiva de Vigotski acerca do tema, sintonizada com as grandes discussões estéticas de seu tempo, é ainda relevante para pensar as manifestações da arte contemporânea, seja em suas vertentes realistas ou no campo da performance.

c, b, and tau lifetime measurements in e+e- interactions

International Nuclear Information System (INIS)

Jaros, J.A.

1983-01-01

Experiments at e + e - storage rings have successfully measured the tau and D 0 lifetimes and set interesting limits on the B lifetime. So far, the conventional wisdom has prevailed. The tau lifetime is consistent with prediction; there is no sign (but little sensitivity) of a violation of universality. The charmed particle lifetimes are roughly as expected, but richer in their phenomenology than anticipated. The B lifetime is still unknown. The experimental art is developing rapidly. Several experiments have by now installed vertex detectors. Measurements of charmed particle lifetimes from e + e - experiments will complement the work that has been done at fixed target machines. Measurements of tau and B lifetimes may be the exclusive province of e + e - experiments for the next few years

Stress granules (SGs) arise as a consequence of cellular stress, contain stalled translation preinitiation complexes, and are associated with cell survival during environmental insults. SGs are dynamic entities with proteins relocating into and out of them during stress. Among the repertoire of proteins present in SGs is eukaryotic initiation factor 4E (eIF4E), a translation factor required for cap-dependent translation and that regulates a rate-limiting step for protein synthesis.

Full Text Available Este trabalho teve por objetivo estudar os efeitos de deriva simulada dos herbicidas clomazone e sulfentrazone em dois clones comerciais de E. grandis x E. urophylla, da Votorantim Celulose e Papel (VCP1 e VCP2. Na simulação, as doses do herbicida clomazone variaram de 0 a 2.000 mL ha-1 e no sulfentrazone, de 0 a 1.500 mL ha-1. As mudas dos dois clones, previamente selecionadas, foram plantadas em vasos com capacidade para 5,0 L. O solo utilizado foi o Neossolo Quartzarênico, sendo a aplicação dos herbicidas realizada 80 dias após o plantio. O delineamento experimental utilizado em cada herbicida foi o de blocos casualizados, com os tratamentos dispostos em esquema fatorial 2 x 8, com três repetições. O efeito do clomazone resultou em folhas novas rosadas, amareladas e, em alguns casos, esbranquiçadas, como um todo ou em parte dela, enquanto as nervuras se mantiveram verdes. Observou-se, também, que as folhas velhas se tornaram mais verdes e grossas. Ocorreu redução nas características de crescimento, variando de 13 a 57%, e as doses consideradas críticas do herbicida clomazone foram de 800 e 1.200 ml ha-1 nos clones VCP1 e VCP2, respectivamente. Com o sulfentrazone, os sintomas da deriva foram necroses generalizadas nas folhas novas e velhas; ao redor da necrose, formaram-se região arroxeada e deformação intensa nas folhas novas e regular nas folhas velhas, bem como houve perda de dominância apical. As características de crescimento indicaram redução de 9 a 66%. A dose crítica desse herbicida foi de 75 ml ha-1 no clone VCP1 e 1.200 ml ha-1 no VCP2. Conclui-se que uma possível deriva dos herbicidas estudados e utilizados em cana-de-açúcar poderá causar prejuízos ao crescimento dos clones avaliados.This research aimed to develop accurate information about the effects of two simulated herbicide drift (clomazone and sulfentrazone on the growth of Votorantim Celulose e Papel Eucalyptus grandis x E. urohylla comercial

Cigarette warning labels are important sources of risk information, but warning research for other tobacco products is limited. This study aimed to gauge perceptions about warnings that may be used for e-cigarettes. We conducted six small focus groups in late 2014/early 2015 with adult current e-cigarette users and cigarette-only smokers. Participants rated and discussed their perceptions of six e-cigarette warning statements, and warnings in two existing Vuse and MarkTen e-cigarette ads. Participants were open to e-cigarette warnings and provided the strongest reactions to statements warning that e-liquid/e-vapor or e-cigarettes can be poisonous, contain toxins, or are "not a safe alternative to smoking". However, many also noted that these statements were exaggerated, potentially misleading, and could scare smokers away from reducing their harm by switching to e-cigarettes. Opinions on the Food and Drug Administration's proposed nicotine addiction warning and warnings that e-cigarettes had not been approved for smoking cessation or had unknown health effects were mixed. Participants perceived MarkTen's advertisement warning to be stronger and more noticeable than Vuse's. Care should be taken in developing e-cigarette warnings given their relative recentness and potential for harm reduction compared to other tobacco products. Additional research, including with varied audiences, would be instructive.

Revisiting radiation patterns in e+e- collisions

International Nuclear Information System (INIS)

Fischer, N.; Gieseke, S.

2014-02-01

We propose four simple event-shape variables for semi-inclusive e + e - →4-jet events. The observables and cuts are designed to be especially sensitive to subleading aspects of the event structure, and allow to test the reliability of phenomenological QCD models in greater detail. Three of them, θ 14 , θ * , and C (1/5) 2 , focus on soft emissions off three-jet topologies with a small opening angle, for which coherence effects beyond the leading QCD dipole pattern are expected to be enhanced. A complementary variable, M 2 L /M 2 H , measures the ratio of the hemisphere masses in 4-jet events with a compressed scale hierarchy (Durham y 23 ∝y 34 ), for which subleading 1→3 splitting effects are expected to be enhanced. We consider several different parton-shower models, spanning both conventional and dipole/antenna ones, all tuned to the same e + e - reference data, and show that a measurement of the proposed observables would allow for additional significant discriminating power between the models.
Strange hadron decays involving e+e- pairs

International Nuclear Information System (INIS)

Soyeur, M.

1996-01-01

A high resolution, large acceptance e + e - detector like HADES coupled to intense secondary kaon beams could offer a remarkable opportunity to study at GSI both the electromagnetic and electroweak decays of strange hadrons. Such data can be very consistently interpreted using effective chiral Lagrangians based on the SU(3) x SU(3) symmetry. Of particular interest are a complete set of data on the electromagnetic form factors for the ρ,ω, φ and K* Dalitz decays, which would put very strong constraints on departures from ideal SU(3) mixings, and measurements of Dalitz decays of hyperons, whose electromagnetic structure is very much unknown. Better data on the nonleptonic radiative (e + e - ) decays of kaons would be most useful to study the strangeness changing weak currents and effects related to CP violation. A major progress in the understanding of these decays came recently from their description in chiral perturbation theory, where the chiral dynamics of Goldstone bosons is coupled to the weak and electromagnetic gauge fields. Those studies could be extended to the electroweak decays of hyperons. (author)

Investigation of correlations in nuclei with the (e,e'X) reaction

International Nuclear Information System (INIS)

Ent, R.

1989-01-01

In this thesis (e,e'd) experiments on 4 He, 6 Li and 12 C, and also a first (e,e'α) experiment on 6 LI are described. The aim of these experiments is twofold: to study the mechanism of (e,e'X) reactions and to extract useful spectroscopic information, i.e. the probability to find a cluster inside a nucleus and the cluster bound-state wave function, from these experiments. Ch. 2 contains a description of the 6 Li(e,e'd) 4 He reaction. The α-d momentum distribution in the ground state of 6 Li has been measured in parallel kinematics in the momentum range 0 m 6 Li. The results agree with the predictions of a three-body αNN model of 6 Li. Ch. 3 deals with deuteron formation in the reaction 12 C(e,e'd) 1O Be. The lowest T=1 state in 1O Be is found to be as strongly excited as the T=0 ground state, although the transition to the T=1 state is isospin forbidden for direct deuteron knockout. The data could consistently be explained by a mechanism of integration of a p-n pair in a relative T=1 state into a deuteron. In ch. 4 the mechanism of the 4 He(e,e'd) 2 H reaction is considered. The cross section for this reaction has been measured as a function of the four-momentum transfer at a missing momentum of 125 MeV/c. The data show that this reaction cannot be described as a quasielastic knockout of the deuteron. The data are compared with a microscopic calculation of the cross section for a direct knockout reaction. Ch. 5 gives an extensive review of all three (e,e'd) experiments. The model of an electron-induced cluster knockout process is discussed in a quasi elastic and a semi-microscopic approach. This description is compared with the data to test the reaction mechanism and the possibility to extract nuclear structure information. In ch. 7 the 6 Li(e,e'α) reaction is considered. This reaction was measured with a special detector, described in Ch. 6. (H.W.). 175 refs.; 32 figs.; 2 tabs

The flux of positrons and electrons (e + + e -) has been measured by the Fermi Large Area Telescope (LAT) in the energy range between 7 GeV and 2 TeV. We discuss a number of interpretations of Pass 8 Fermi-LAT e + + e - spectrum, combining electron and positron emission from supernova remnants (SNRs) and pulsar wind nebulae (PWNe), or produced by the collision of cosmic rays (CRs) with the interstellar medium. We find that the Fermi-LAT spectrum is compatible with the sum of electrons from a smooth SNR population, positrons from cataloged PWNe, and a secondary component. If we include in our analysis constraints from the AMS-02 positron spectrum, we obtain a slightly worse fit to the e + + e - Fermi-LAT spectrum, depending on the propagation model. As an additional scenario, we replace the smooth SNR component within 0.7 kpc with the individual sources found in Green’s catalog of Galactic SNRs. We find that separate consideration of far and near sources helps to reproduce the e + + e - Fermi-LAT spectrum. However, we show that the fit degrades when the radio constraints on the positron emission from Vela SNR (which is the main contributor at high energies) are taken into account. We find that a break in the power-law injection spectrum at about 100 GeV can also reproduce the measured e + + e - spectrum and, among the CR propagation models that we consider, no reasonable break of the power-law dependence of the diffusion coefficient can modify the electron flux enough to reproduce the observed shape.

Canadian National with 21,000 miles of tracks from coast to coast, 22,000 employees and over four billion dollars in revenue, is one of North America's most efficient railway companies. This discussion paper outlines the steps CN is taking to meet the challenge of e-commerce. Two major competing forces have been identified as the principal influences on shaping customer channels: collaboration (forces striving to integrate manufacturers with their customers using e-commerce to provide a lower cost supply chain) and disaggregation (forces striving to put the supply chain decision in the hands of the receivers by using e-commerce). CN's assessment is that the changes wrought to the traditional relationship between manufactures, transportation companies and consumers, will demand consolidation of carrier relationships, outsourcing and relocation to the Internet, and integrating the Internet into existing logistics operations. Although CN has been doing electronic data interchange with customers and partners since 1982, it is evident that existing rail processes need to be changed further to meet the new demands. CN's strategy of how to implement the required changes and the elements of the new strategy are reviewed. 18 viewgraphs.

Production of axinos and photinos in e + e - and γγ collisions is calculated and estimated. It is shown that there is an upper limit of the cross section for the process e - e + → a-tildeγ-tilde c dependent only on the breaking scale. For the process γγ → a-tildea-tilde c , there is a special direction in which axinos are mainly produced. Behaviour of cross section for this process is also analysed. Based on the result a new constraint for F/N is derived: F/N ≥ 10 14 GeV. (author)

Direito, estado e poder: poulantzas e o seu confronto com Kelsen

Directory of Open Access Journals (Sweden)

Luiz Eduardo Motta

2011-02-01

Full Text Available A Teoria do Estado, no campo da Ciência Política, viveu momentos de crise, em particular na passagem dos anos 1980 para os 1990, quando algumas correntes intelectuais apontavam que o Estado-nação e as instituições estatais deixariam de ocupar um papel central como objetos de análise. O presente artigo vai de encontro a essa posição e visa a estabelecer uma análise comparativa de dois dos mais sistemáticos autores que trataram do conceito de Estado moderno e da relação deste com o Direito moderno: Hans Kelsen e Nicos Poulantzas. O ponto de partida é a analogia estabelecida entre ambos por David Easton, em seu artigo O sistema político sitiado pelo Estado, que identifica a obra marxista de Poulantzas com a teoria sistêmica e normativa de Kelsen sobre o Direito e o Estado. De fato, paradoxalmente, Poulantzas converge em muitos aspectos com Kelsen quando critica o pensamento liberal (ao qual Kelsen é filiado e quando define que o Estado de Direito seria a antítese dos estados autoritários. Mas, a despeito dessas convergências, as diferenças entre Poulantzas e Kelsen demarcam duas formas distintas no trato teórico e político sobre os conceitos de Direito e Estado. Para Kelsen, o Estado é impermeável, não havendo contradições e fissuras internas, enquanto, para Poulantzas, o Estado é definido como um campo estratégico de lutas, permeado de micropolíticas e de contradições. O artigo é composto de uma introdução, seguida por duas seções que sistematizam as principais definições de Kelsen e Poulantzas sobre o papel do Estado e do Direito modernos, além de uma conclusão, que demarca os aspectos convergentes e divergentes entre os dois autores

An experiment was carried out to study the character of the resonance observed at 24.4 MeV in the /sup 140/Ce (..gamma.., p) /sup 139/La reaction. The (..gamma.., p/sub 0/ + p/sub 1/) cross section was measured at the angles of 54.7/sup 0/ and 125.3/sup 0/, at which the angle-dependent term of E1 becomes zero, for the energy range between 19 and 26 MeV. Existence of a peak due to the E2 resonance around 24.4 MeV was examined. The energy of incident electrons from a linear accelerator was changed between 20 and 26.7 MeV. The target was a Ce foil of 7.3 mg/cm/sup 2/ thick. The proton spectra due to the /sup 140/Ce (e, e' p) /sup 139/La reaction were measured with a broad range magnetic spectrometer. In the determined spectra of /sup 140/Ce (..gamma.., p/sub 0/+p/sub 1/) /sup 139/La, any remarkable peak, except one at 20.5 MeV, was not seen. From the observed spectra, the total cross section and the asymmetry factor due to interference were obtained as functions of energy. The values of the asymmetry factor were almost flat in the energy range between 19 and 26 MeV. The resonance at 24.4 MeV in the total cross section may be due to the E1 resonance, and is not due to the E2.

Full Text Available Mucosal tolerance to E-selectin prevents stroke and protects against ischemic brain damage in experimental models of stroke studying healthy animals or spontaneously hypertensive stroke-prone rats. A reduction in inflammation and neural damage was associated with immunomodulatory or "tolerogenic" responses to E-selectin. The purpose of the current study on ApoE deficient mice is to assess the capacity of this stroke prevention innovation to influence atherosclerosis, a major underlying cause for ischemic strokes; human E-selectin is being translated as a potential clinical prevention strategy for secondary stroke. Female ApoE-/- mice received intranasal delivery of E-selectin prior to (pre-tolerization or simultaneously with initiation of a high-fat diet. After 7 weeks on the high-fat diet, lipid lesions in the aorta, serum triglycerides, and total cholesterol were assessed as markers of atherosclerosis development. We also assessed E-selectin-specific antibodies and cytokine responses, in addition to inflammatory responses that included macrophage infiltration of the aorta and altered gene expression profiles of aortic mRNA. Intranasal delivery of E-selectin prior to initiation of high-fat chow decreased atherosclerosis, serum total cholesterol, and expression of the leucocyte chemoattractant CCL21 that is typically upregulated in atherosclerotic lesions of ApoE-/- mice. This response was associated with the induction of E-selectin specific cells producing the immunomodulatory cytokine IL-10 and immunosuppressive antibody isotypes. Intranasal administration of E-selectin generates E-selectin specific immune responses that are immunosuppressive in nature and can ameliorate atherosclerosis, a major risk factor for ischemic stroke. These results provide additional preclinical support for the potential of induction of mucosal tolerance to E-selectin to prevent stroke.

Full Text Available In modern education, an e-portfolio platform helps students in acquiring e-learning objects in a learning activity. Quality is an important consideration in evaluating the desirable e-learning object. Finding a means of determining a high quality e-learning object from a large number of candidate e-learning objects is an important requirement. To assist student learning in a modern e-portfolio platform, this work proposed an optimal selection approach determining a reasonable e-learning object from various candidate e-learning objects. An optimal selection approach which uses advanced information techniques is proposed. Each e-learning object undergoes a formalization process. An Information Retrieval (IR technique extracts and analyses key concepts from the student’s previous learning contexts. A context-based utility model computes the expected utility values of various e-learning objects based on the extracted key concepts. The expected utility values of e-learning objects are used in a multicriteria decision analysis to determine the optimal selection order of the candidate e-learning objects. The main contribution of this work is the demonstration of an effective e-learning object selection method which is easy to implement within an e-portfolio platform and which makes it smarter.

Full Text Available Investigou-se a qualidade microbiológica do leite in natura e na linha de produção (leite recém-pasteurizado e leite ensacado, de uma usina de beneficiamento em Campina Grande-PB. Foi pesquisada a presença de Listeria spp. e sua diversidade de espécies, os níveis de coliformes totais (CT, coliformes fecais (CF e Escherichia coli. Analisou-se um total de 75 amostras de leite, sendo 45 de leite cru, 15 de leite recém-pasteurizado e 15 de leite ensacado. Os resultados foram reunidos em dois grupos segundo o período de monitoramento: antes e após mudanças no processo de higienização da usina. Foi evidenciada elevada contaminação nas amostras de leite cru nas duas épocas. Na primeira (março-abril/1998, todas as amostras de leite beneficiado estiveram fora dos padrões da legislação vigente para CT e CF; na segunda (maio-agosto/1998, houve acentuada redução dos níveis destas bactérias indicadoras, porém as melhorias na higienização não foram suficientes para solucionar este problema, visto que 11,1% das amostras recém-pasteurizadas estavam fora dos padrões para CT e 33,3% para CF. Das amostras ensacadas, 22,2% estavam fora dos padrões para CT e 44,4% para CF. Comparando-se os resultados de CT, CF, e E.coli nas amostras de leite recém-pasteurizado e não ensacado com as amostras de leite ensacado, foi verificado que as amostras após serem pasteurizadas e ensacadas apresentaram valores de CT e CF levemente mais elevados, sugerindo contaminação durante o processo de ensacamento ou falhas na armazenagem.

LA PAROLA E IL SILENZIO IN VIRGINIA WOOLF E NATHALIE SARRAUTE

Full Text Available L’idea della creazione letteraria come equivalente verbale di una realtà altra, come trasposizione dall’ordine della sensazione o del pensiero all’ordine della parola, accomuna la concezione estetica di Virginia Woolf a quella di Nathalie Sarraute. Ambedue le scrittrici manifestano una smisurata fascinazione nei confronti del linguaggio pur non perdendone di vista i limiti e le manchevolezze, che rendono necessario lo sforzo di ricondurlo alle sue origini preverbali, emotive, pulsionali. L’enfasi, infatti, è posta sull’incommensurabilità tra una realtà fluttuante e amorfa quale è l’universo psichico, o la labilità delle impressioni, e la fissità, la rigidezza, la linearità del medium linguistico, che rischia in ogni momento di immobilizzare e devitalizzare la sensazione o il pensiero di cui è espressione. Entrambe le autrici esplorano dunque le potenzialità della sfera del nondetto, di quel silenzio che talvolta possiede un valore comunicativo superiore a quello della parola e ne evidenzia/compensa i limiti, manifestando una assenza e al contempo un surplus di significato. Lo stile di Virginia Woolf e di Nathalie Sarraute si farà quindi vago e allusivo, secondo un’estetica dell’indeterminatezza e dell’incompiuto (data, tra l’altro, dall’uso pervasivo dell’ellissi e dei puntini di sospensione finalizzata a congiungere la sfera psichica e la realtà del linguaggio, anche tramite la sua assenza.
The Distribution of eIF4E-Family Members across Insecta

Full Text Available Insects are part of the earliest faunas that invaded terrestrial environments and are the first organisms that evolved controlled flight. Nowadays, insects are the most diverse animal group on the planet and comprise the majority of extant animal species described. Moreover, they have a huge impact in the biosphere as well as in all aspects of human life and economy; therefore understanding all aspects of insect biology is of great importance. In insects, as in all cells, translation is a fundamental process for gene expression. However, translation in insects has been mostly studied only in the model organism Drosophila melanogaster. We used all publicly available genomic sequences to investigate in insects the distribution of the genes encoding the cap-binding protein eIF4E, a protein that plays a crucial role in eukaryotic translation. We found that there is a diversity of multiple ortholog genes encoding eIF4E isoforms within the genus Drosophila. In striking contrast, insects outside this genus contain only a single eIF4E gene, related to D. melanogaster eIF4E-1. We also found that all insect species here analyzed contain only one Class II gene, termed 4E-HP. We discuss the possible evolutionary causes originating the multiplicity of eIF4E genes within the genus Drosophila.

Cigarette warning labels are important sources of risk information, but warning research for other tobacco products is limited. This study aimed to gauge perceptions about warnings that may be used for e-cigarettes. We conducted six small focus groups in late 2014/early 2015 with adult current e-cigarette users and cigarette-only smokers. Participants rated and discussed their perceptions of six e-cigarette warning statements, and warnings in two existing Vuse and MarkTen e-cigarette ads. Participants were open to e-cigarette warnings and provided the strongest reactions to statements warning that e-liquid/e-vapor or e-cigarettes can be poisonous, contain toxins, or are “not a safe alternative to smoking”. However, many also noted that these statements were exaggerated, potentially misleading, and could scare smokers away from reducing their harm by switching to e-cigarettes. Opinions on the Food and Drug Administration’s proposed nicotine addiction warning and warnings that e-cigarettes had not been approved for smoking cessation or had unknown health effects were mixed. Participants perceived MarkTen’s advertisement warning to be stronger and more noticeable than Vuse’s. Care should be taken in developing e-cigarette warnings given their relative recentness and potential for harm reduction compared to other tobacco products. Additional research, including with varied audiences, would be instructive. PMID:27376310

We have measured (e,2e) triple differential cross sections (TDCS) for the electron-impact ionisation of phenol with coplanar asymmetrical kinematics for an incident electron energy of 250 eV. Experimental measurements of the angular distribution of the slow outgoing electrons at 20 eV are obtained when the incident electron scatters through angles of −5°, −10°, and −15°, respectively. The TDCS data are compared with calculations performed within the molecular 3-body distorted wave model. In this case, a mixed level of agreement, that was dependent on the kinematical condition being probed, was observed between the theoretical and experimental results in the binary peak region. The experimental intensity of the recoil features under all kinematical conditions was relatively small, but was still largely underestimated by the theoretical calculations.
A short history of e+e- storage rings

International Nuclear Information System (INIS)

Perez-y-Jorba, J.

A quick survey of the history of electron-positron colliding-beam physics is given. First, the main physical characteristics of storage rings are recalled and the kinematical and dynamical properties of e + e - annihilation reactions are described. Then an account is made of the most important results obtained in particle physics with e + e - colliding rings. With the first generation of machines at low energies, the precise study of the vector mesons and the form factors of pions and kaons was made. Then at intermediate energies came the astonishing result that the total cross-section was keeping much higher than previously expected. Last but not least, a new realm of physics was opened by the discovery of the new particles, of their decays to intermediate states, by the possible existence of heavy leptons and of charmed mesons

The potential savings of transaction costs from e-commerce are substantial. The most important cost-saving aspect of e-commerce is the reduction in travel, administration, communication and search costs. One consequence of such cost advantages is that many small cross-border transactions have now become economic. In addi...

To date, no genome-wide association study (GWAS) has considered the combined phenotype of asthma with hay fever. Previous analyses of family data from the Tasmanian Longitudinal Health Study provide evidence that this phenotype has a stronger genetic cause than asthma without hay fever. We sought to perform a GWAS of asthma with hay fever to identify variants associated with having both diseases. We performed a meta-analysis of GWASs comparing persons with both physician-diagnosed asthma and hay fever (n = 6,685) with persons with neither disease (n = 14,091). At genome-wide significance, we identified 11 independent variants associated with the risk of having asthma with hay fever, including 2 associations reaching this level of significance with allergic disease for the first time: ZBTB10 (rs7009110; odds ratio [OR], 1.14; P = 4 × 10(-9)) and CLEC16A (rs62026376; OR, 1.17; P = 1 × 10(-8)). The rs62026376:C allele associated with increased asthma with hay fever risk has been found to be associated also with decreased expression of the nearby DEXI gene in monocytes. The 11 variants were associated with the risk of asthma and hay fever separately, but the estimated associations with the individual phenotypes were weaker than with the combined asthma with hay fever phenotype. A variant near LRRC32 was a stronger risk factor for hay fever than for asthma, whereas the reverse was observed for variants in/near GSDMA and TSLP. Single nucleotide polymorphisms with suggestive evidence for association with asthma with hay fever risk included rs41295115 near IL2RA (OR, 1.28; P = 5 × 10(-7)) and rs76043829 in TNS1 (OR, 1.23; P = 2 × 10(-6)). By focusing on the combined phenotype of asthma with hay fever, variants associated with the risk of allergic disease can be identified with greater efficiency.

Full Text Available As pessoas com deficiência costumam ser estigmatizadas e excluídas do convívio social e das atividades consideradas normais. Para transformar essa realidade, a Assembléia Geral da ONU (1990 enfatizou o modelo de sociedade inclusiva, baseado no princípio de que todas as pessoas têm o mesmo valor e que a sociedade deve empenhar-se para atender as diferentes necessidades de cada cidadão. Dentro dessa visão, foi criado o Grupo de Teatro para Atores Especiais (G.T.P.A.Ê., com o objetivo principal de possibilitar o desenvolvimento das habilidades pessoais e sociais da pessoa com deficiência mental, além de informar a sociedade sobre as reais potencialidades e limitações desses indivíduos. A intervenção se desenvolve durante laboratórios de teatro, passeios noturnos e apresentações do grupo. É possível observar expressões criativas dos participantes, assim como o desenvolvimento de autonomia e auto-estima. Também se observa um impacto das apresentações no público, que pode levar à diminuição de preconceitos e facilitar o processo de inclusão.

Full Text Available Nosso objetivo é discutir os processos de objetivação, desqualificação e criminalização de uma comunidade tradicional de pescadores situada na orla urbana de Maceió, que trava uma luta contra a prefeitura municipal pelo direito à permanência e por investimentos nesse território. Com base nas pesquisas de Michel Foucault, propomos uma problematização dessas formas de objetivação, subjetivação e governo, analisando práticas e saberes que incidem sobre essa comunidade. Usamos registros produzidos em quatro anos de trabalho com essa comunidade, bem como documentos e materiais midiáticos que abordam o conflito. Discutimos a judicialização da vida em torno de dois aspectos: a discursos que operam como condições de possibilidade para sustentar a proposta de remoção dessa comunidade de seu território; b estratégias de resistência que afirmam a especificidade da vida nesse lugar. Trazemos esta situação para o debate sobre a judicialização da vida buscando não apenas problematizar as circunstâncias em que se passa a demandar mais intervenção jurídica no governo da vida, mas também afirmar que o que está em jogo nessa situação não é a mera aplicação e cumprimento da lei, e sim, os modos de vida dessa comunidade que confrontam a lógica de investimento e desenvolvimento urbano da cidade.

No obstante, al realizar el análisis por clúster, que amplía y actualiza trabajos anteriores, se constata cómo en los distintos momentos hay una mayor preferencia por determinados términos o por determinadas competencias. Igualmente, este tipo de análisis evidencia que, aunque hay distintos trabajos que han definido, diferenciado y clasificado las competencias informacionales e informáticas, presentando como nivel complementario y precedente las segundas, en muchas áreas de conocimiento, esta diferenciación no es tan clara y hay un menor énfasis en las competencias informacionales desde la perspectiva actual ("information literacy" y/o "information skills", lo cual implica, para los profesionales de la información, seguir trabajando por el posicionamiento, tanto a nivel educativo como empresarial, de la necesidad de una formación continua en las competencias informacionales como elemento fundamental para el aprendizaje para toda la vida.In this work, the terms that best represent the training in information and computer competencies the last 30

We present a search for a neutral, long-lived particle L that is produced in e+ e- collisions and decays at a significant distance from the e+ e- interaction point into various flavor combinations of two oppositely charged tracks. The analysis uses an e+ e- data sample with a luminosity of 489.1 fb(-1) collected by the BABAR detector at the ϒ(4S), ϒ(3S), and ϒ(2S) resonances and just below the ϒ(4S). Fitting the two-track mass distribution in search of a signal peak, we do not observe a significant signal, and set 90% confidence level upper limits on the product of the L production cross section, branching fraction, and reconstruction efficiency for six possible two-body L decay modes as a function of the L mass. The efficiency is given for each final state as a function of the mass, lifetime, and transverse momentum of the candidate, allowing application of the upper limits to any production model. In addition, upper limits are provided on the branching fraction B(B→XsL), where Xs is a strange hadronic system.
μ+e-↔μ-e+ transitions via neutral scalar bosons

International Nuclear Information System (INIS)

Hou, W.; Wong, G.

1996-01-01

With μ→eγ decay forbidden by multiplicative lepton number conservation, we study muonium-antimuonium transitions induced by neutral scalar bosons. Pseudoscalars do not induce conversion for triplet muonium, while, for singlet muonium, pseudoscalar and scalar contributions add constructively. This is in contrast with the usual case of doubly charged scalar exchange, where the conversion rate is the same for both singlet and triplet muonium. Complementary to muonium conversion studies, high energy μ + e - →μ - e + and e - e - →μ - μ - collisions could reveal spectacular resonance peaks for the cases of neutral and doubly charged scalars, respectively. copyright 1996 The American Physical Society

Full Text Available O artigo analisa os conceitos e práticas da viagem e do turismo baseado nas discussões sobre as características do fenômeno e de sua gênese. A viagem é então entendida a partir dos estudos da natureza e da cultura e como essas duas categorias se relacionam entre si, de acordo com os estudos antropológicos de Malinowski, Claude Levi-Strauss e Clifford Geertz. É evidenciada a interpretação da viagem como universal cultural, no entanto, nao se pode entendê-la como um aspecto da “natureza humana”. O turismo é entendido como um tipo de viagem cuja origem e características surgiram no mundo moderno.
The electroweak interaction in e+e- annihilations

The Plane Wave Impulse Approximation is used to analyse the experimental cross-section for the Argon (e,2e) reaction (using the non-coplanar symmetric geometry). A series of Configuration Interaction calculations for the structure of Ar I and Ar II are reported demonstrating that correlation effects have only a minor effect on the momentum distributions (which are well described by the Target Hartree-Fock Approximation). Fair agreement between the theoretical and experimental spectroscopic factors for the separation energy spectrum is obtained, and in particular the distribution of strength amongst the 3s 2 3p 4 nd 2 S/sup e/ satellite states specified by the largest calculations is in better agreement with data than that obtained with simple structure models

Full Text Available Pretende-se refletir, a partir da história do povo Chiquitano, originalmente um conjunto de mais de vinte etnias que foram aldeadas pelos jesuítas na missão de Chiquitos, elementos de sua identidade e etnicidade contemporâneas. A proposta que se apresenta é a de entender como se situam atualmente as identidades, relacionadas com as territorialidades experienciadas na Bolívia e no Brasil, uma vez que este povo está atualmente cindido parcialmente pelo fato de terem sido fracionados em duas partes a partir da divisão dos estados nacionais. O fato de viverem em um ou outro país provoca diferentes experiências e proposições identitárias; no entanto, até a década de 1980, a fronteira entre os dois países, ainda não totalmente institucionalizada, permitia um trânsito de um para outro lado, mas para além disso, permitia relações sociais e manutenção de redes de parentesco. Como se desenham as identidades atualmente, na diversidade territorial e histórica? Como estão desenhadas as territorialidades dos Chiquitanos na Bolívia e no Brasil se as políticas indigenistas são distintas? Como ocorrem as autoidentificações, sendo que há distintos conceitos para “índios” – aqui, povos indígenas e, na Bolívia, “campesino” ou “pueblos originales”? De que maneira o reconhecimento oficial da etnicidade dos Chiquitanos no Brasil trouxe novos elementos suscitadores de conflitos? Estas são questões que se pretende responder neste artigo.

Vitamin E Nicotinate

Kimbell R. Duncan

Full Text Available Vitamin E refers to a family of compounds that function as lipid-soluble antioxidants capable of preventing lipid peroxidation. Naturally occurring forms of vitamin E include tocopherols and tocotrienols. Vitamin E in dietary supplements and fortified foods is often an esterified form of α-tocopherol, the most common esters being acetate and succinate. The vitamin E esters are hydrolyzed and converted into free α-tocopherol prior to absorption in the intestinal tract. Because its functions are relevant to many chronic diseases, vitamin E has been extensively studied in respect to a variety of diseases as well as cosmetic applications. The forms of vitamin E most studied are natural α-tocopherol and the esters α-tocopheryl acetate and α-tocopheryl succinate. A small number of studies include or focus on another ester form, α-tocopheryl nicotinate, an ester of vitamin E and niacin. Some of these studies raise the possibility of differences in metabolism and in efficacy between vitamin E nicotinate and other forms of vitamin E. Recently, through metabolomics studies, we identified that α-tocopheryl nicotinate occurs endogenously in the heart and that its level is dramatically decreased in heart failure, indicating the possible biological importance of this vitamin E ester. Since knowledge about vitamin E nicotinate is not readily available in the literature, the purpose of this review is to summarize and evaluate published reports, specifically with respect to α-tocopheryl nicotinate with an emphasis on the differences from natural α-tocopherol or α-tocopheryl acetate.

The present study determined the chemical composition, fatty acid (FA) content and antioxidant capacity of meat from goats supplemented with Moringa oleifera leaves (MOL) or sunflower cake (SC) or grass hay (GH). The meat from goat supplemented with MOL had higher concentrations of total phenolic content (10.62±0.27 mg tannic acid equivalent E/g). The MOL significantly scavenged 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic-acid (ABTS) radical to 93.51±0.19% (93.51±0.19%) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical to 58.95±0.3% than other supplements. The antioxidative effect of MOL supplemented meat on catalase (CAT), reduced glutathione (GSH), superoxide dismutase (SOD) and lipid oxidation (LO) was significantly (Pmeat from goat feed on grass hay or those supplemented with sunflower seed cake. The present study indicated that the anti-oxidative potential of MOL may play a role in improving meat quality (chemical composition, colour and lipid stability). Copyright © 2012 Elsevier Ltd.

E-cigarettes: Impact of E-Liquid Components and Device Characteristics on Nicotine Exposure.

Science.gov (United States)

DeVito, Elise E; Krishnan-Sarin, Suchitra

2018-01-01

Electronic cigarette (e-cigarette) use has increased substantially in recent years. While e-cigarettes have been proposed as a potentially effective smoking cessation tool, dualuse in smokers is common and e-cigarettes are widely used by non-smokers, including youth and young-adult non-smokers. Nicotine, the primary addictive component in cigarettes, is present at varying levels in many e-liquids. E-cigarettes may lead to initiation of nicotine use in adult and youth non-smokers, re-initiation of nicotine dependence in ex-smokers or increased severity of nicotine dependence in dual-users of cigarettes and e-cigarettes. As such, there are important clinical and policy implications to understanding factors impacting nicotine exposure from e-cigarettes. However, the broad and rapidly changing range of e-liquid constituents and e-cigarette hardware which could impact nicotine exposure presents a challenge. Recent changes in regulatory oversight of e-cigarettes underscore the importance of synthesizing current knowledge on common factors which may impact nicotine exposure. This review focuses on factors which may impact nicotine exposure by changing e-cigarette use behavior, puff topography, altering the nicotine yield (amount of nicotine exiting the e-cigarette mouth piece including nicotine exhaled as vapor) or more directly by altering nicotine absorption and bioavailability. Topics reviewed include e-liquid components or characteristics including flavor additives (e.g., menthol), base e-liquid ingredients (propylene glycol, vegetable glycerin), components commonly used to dissolve flavorants (e.g., ethanol), and resulting properties of the e-liquid (e.g., pH), e-cigarette device characteristics (e.g., wattage, temperature, model) and user behavior (e.g., puff topography) which may impact nicotine exposure. E-liquid characteristics and components, e-cigarette hardware and settings, and user behavior can all contribute substantially to nicotine exposure from e

Full Text Available O objetivo deste artigo é discutir o papel social da escola sob o ângulo da experiência estudantil e das relações que os alunos estabelecem com as regras. Relatamos um estudo de caso feito a partir de entrevistas com duas alunas ingressantes no ensino médio. Em seu discurso, as alunas criticaram o funcionamento da escola e demandaram mais disciplina e regras mais rigorosas. Em nossa análise, refletimos sobre a construção histórica da escola como instrumento disciplinar. Em seguida, analisamos os sentidos conferidos pelas alunas às experiências escolares, à família, à adolescência, às regras e ao futuro profissional. Discutimos o pedido por mais disciplina feito pelas alunas, tendo em vista, além do contexto sociohistórico, o conjunto de suas práticas, vivências e sentidos subjetivos. Afirmamos que, para construir uma escola capaz de promover autonomia, os educadores precisam considerar esses sentidos subjetivos, e as práticas escolares devem contemplar análises da existência psicossocial. Para concluir, afirmamos que a escola deve sustentar seu lugar de autoridade e referência para os jovens e, ao mesmo tempo, abrir-se para a compreensão e para a incorporação da alteridade.

Afirma que existe uma relação intrínseca entre patrimônio e poder, que permanece na relação entre patrimônio e propriedade, seja material ou espiritual, econômica ou simbólica e a sua vinculação à idéia de preservação. Destaca que a noção de posse parece ser mais adequada aos museus do que a de propriedade Sugere que o caráter preservacionista e o sentido de posse estão na raiz da instituição do patrimônio e do museu (casa de memória e poder. Ressalta que a preservação como prática social que é utilizada para a construção de determinadas narrativas tem um caráter subjetivo, que é mascarado por discursos que se pretendem positivos, científicos e objetivos.

La ballata E5 e le sue varianti nel codice degli abbozzi

Full Text Available La ballata petrarchesca Amor, che ’n cielo e ’n cor gentile alberghi (E5, composta per il musico Confortino e destinata alla definitiva esclusione dal Canzoniere, è un componimento profondamente complesso, oltre che caratterizzato da un’intrigante vicenda redazionale. E5 appare infatti imperniata sull’ambiguità tra due poli opposti, amoroso e religioso, in un gioco di contrapposizioni che rende difficile scegliere in via definitiva tra un’interpretazione sentimentale ed una lettura morale o addirittura penitenziale. La ballata è inoltre caratterizzata dall’evidente ed esteso riuso della tradizione lirica ed in particolare dei modelli stilnovistici, non solo e non tanto sul piano degli stilemi e delle immagini, quanto in termini di concezione amorosa. Il rapporto con queste fonti risulta problematico, tra ripresa e negazione, e rappresenta un ulteriore nodo significativo rispetto all’interpretazione del componimento. La graduale evoluzione della ballata, di cui possono essere identificate per lo meno tre versioni distinte, sembra accentuare gli elementi di complessità e le sovrapposizioni semantiche. Infine, l’analisi formale e contenutistica di E5 favorisce la formulazione, pur senza pretesa di certezza, di ipotesi sulle ragioni della sua sorte extravagante

Toward automated e-cigarette surveillance: Spotting e-cigarette proponents on Twitter.

Kavuluru, Ramakanth; Sabbir, A K M

2016-06-01

Electronic cigarettes (e-cigarettes or e-cigs) are a popular emerging tobacco product. Because e-cigs do not generate toxic tobacco combustion products that result from smoking regular cigarettes, they are sometimes perceived and promoted as a less harmful alternative to smoking and also as means to quit smoking. However, the safety of e-cigs and their efficacy in supporting smoking cessation is yet to be determined. Importantly, the federal drug administration (FDA) currently does not regulate e-cigs and as such their manufacturing, marketing, and sale is not subject to the rules that apply to traditional cigarettes. A number of manufacturers, advocates, and e-cig users are actively promoting e-cigs on Twitter. We develop a high accuracy supervised predictive model to automatically identify e-cig "proponents" on Twitter and analyze the quantitative variation of their tweeting behavior along popular themes when compared with other Twitter users (or tweeters). Using a dataset of 1000 independently annotated Twitter profiles by two different annotators, we employed a variety of textual features from latest tweet content and tweeter profile biography to build predictive models to automatically identify proponent tweeters. We used a set of manually curated key phrases to analyze e-cig proponent tweets from a corpus of over one million e-cig tweets along well known e-cig themes and compared the results with those generated by regular tweeters. Our model identifies e-cig proponents with 97% precision, 86% recall, 91% F-score, and 96% overall accuracy, with tight 95% confidence intervals. We find that as opposed to regular tweeters that form over 90% of the dataset, e-cig proponents are a much smaller subset but tweet two to five times more than regular tweeters. Proponents also disproportionately (one to two orders of magnitude more) highlight e-cig flavors, their smoke-free and potential harm reduction aspects, and their claimed use in smoking cessation. Given FDA is

Local E11

Riccioni, Fabio; West, Peter

2009-01-01

We give a method of deriving the field-strengths of all massless and massive maximal supergravity theories in any dimension starting from the Kac-Moody algebra E 11 . Considering the subalgebra of E 11 that acts on the fields in the non-linear realisation as a global symmetry, we show how this is promoted to a gauge symmetry enlarging the algebra by the inclusion of additional generators. We show how this works in eleven dimensions, and we call the resulting enlarged algebra E 11 local . Torus reduction to D dimensions corresponds to taking a subalgebra of E 11 local , called E 11,D local , that encodes the full gauge algebra of the corresponding D-dimensional massless supergravity. We show that each massive maximal supergravity in D dimensions is a non-linear realisation of an algebra E-tilde 11,D local . We show how this works in detail for the case of Scherk-Schwarz reduction of IIB to nine dimensions, and in particular we show how E-tilde 11,9 local arises as a subalgebra of the algebra E 11,10B local associated to the ten-dimensional IIB theory. This subalgebra corresponds to taking a combination of generators which is different to the massless case. We then show that E-tilde 11,D local appears as a deformation of the massless algebra E 11,D local in which the commutation relations between the E 11 and the additional generators are modified. We explicitly illustrate how the deformed algebra is constructed in the case of massive IIA and of gauged five-dimensional supergravity. These results prove the naturalness and power of the method.
Production of sleptons in e-e--collisions

International Nuclear Information System (INIS)

Wagner, Alexander

2008-01-01

In this work, the use of an e - e - -collider for the search for CP violation and LFV has been studied. For this purpose the total production cross section for arbitrary sleptons in e - e - -scattering has been calculated on tree level, allowing for all possible polarisation modes, i. e. longitudinal and transverse polarisation of both incoming beams. Additionally, all possible mixings in the slepton sector, particularly LR mixing and LFV, have been taken into account, and the slepton mass matrix as well as the neutralino mass matrix have been treated as complex matrices allowing for CP violation in either sector. In an analytical approximation neglecting LR mixing in the slepton sector of the MSSM, it has been shown that, even by conforming to all current experimental bounds on LFV, it is possible to obtain a large slepton mixing. In particular, it has been found that the selectron and smuon states are allowed to form sleptons of equal admixtures of both components. Another result of the analytical calculation shows, that one of the sleptons only contains a negligible stau component, and that throughout, this slepton is determined to be the slepton of intermediate mass. These analytical results were supported by numerical calculations in various representative scenarios. The squared amplitude for the production process e - e - → l a l b has been calculated and presented in both the covariant form, as well as in the centre of mass system. All possible modes of polarisation have been taken into account. It has been possible to construct a CP-sensitive observable using transverse polarisation of both beams. The influence of the CP-violating phases φ M 1 and φ μ on the total production cross section has been investigated including full neutralino mixing. It has been shown, that measurable effects can be expected even in the associate production of a left and right selectron. For the study of LFV the analytical approximations have been checked numerically and

Higgs production at future e + e - colliders in the Georgi-Machacek model

We study how the dominant single and double SM-like Higgs ( h) production at future e + e - colliders is modified in the Georgi-Machacek (GM) model. On imposing theoretical, indirect and direct constraints, significant deviations of h-couplings from their SM values are still possible; for instance, the Higgs-gauge coupling can be corrected by a factor κ hV V ∈ [0 .93 , 1 .15] in the allowed parameter space. For the Higgs-strahlung e + e - → hZ and vector boson fusion processes {e}+{e}-\\to hν \\overline{ν} , he + e -, the cross section could increase by 32% or decrease by 13%. In the case of associated production with a top quark pair {e}+{e}-\\to ht\\overline{t} , the cross section can be enhanced up to several times when the custodial triplet scalar H 3 0 is resonantly produced. In the meanwhile, the double Higgs production {e}+{e}-\\to hhZ(hhν \\overline{ν}) can be maximally enhanced by one order of magnitude at the resonant H 1,3 0 production. We also include exclusion limits expected from future LHC runs at higher energy and luminosity and discuss their further constraints on the relevant model parameters. We find that the GM model can result in likely measurable deviations of Higgs production from the SM at future e + e - colliders.

Full Text Available The objective of this work was to evaluate the performance of Holstein calves in suckling and post-weaning phases, intensively managed during suckling in the absence or presence of hay. Twenty-four male Holstein calves, at an average age of 15 days and initial weight of 43 kg were used in the experiment. The experimental design was completely randomized, consisting of two treatments and six replications. The treatments were as follows: 1 suckling with milk substitute + initial concentrate for calves, ad libitum + temperate grass hay (oat/ryegrass, ad libitum; 2 suckling with milk substitute + initial concentrate for calves, ad libitum. No significant difference was found between treatments for weight gain and feed conversion. However, the supply of hay caused an increase in daily dry matter intake (2.127 vs 1.894 kg. The intake of hay promoted greater stimulus to consumption of concentrate and greater weight at weaning.
Bounds on new contact interactions from future e+e- colliders

1988-01-01

A systematic study of the 'reach' for contact interactions as a probe for new physics at future e + e - colliders is performed. A large energy range is considered, from PETRA/PEP energies at the lower end, via the Z 0 peak (SLC/LEP-I) and LEP-II, up to the TeV regime of a potential future linear e + e - collider. Lower bounds on the compositeness scale Λ for leptons are calculated for Bhabha scattering and μ-pair production using realistic assumptions on the expected luminosities and detector performances. The impact of longitudinal and transverse polarization is studied in detail. The 'reach' corresponding to high rates at the Z 0 peak is compared to the one obtained from running at higher energies. At LEP-II energies, a sensitivity to (lepton) substructure at the level of Λ ≅ 10 TeV is to be expected. At a 2 TeV e + e - collider the sensitivity can be as large as 100 TeV. (orig.)

Luminosity, Beamstrahlung energy loss and beam-beam deflections for e+e- and e-e- collisions at the ILC with 500 GeV and varying transverse beam sizes

International Nuclear Information System (INIS)

Alabau Pons, M.; Bambade, P.; Faus-Golfe, A.

2006-01-01

At the interaction point of the International Linear Collider, beam-beam effects due to the strong electromagnetic fields that the bunches experience during collisions cause a mutual focusing, called pinch effect, which enhances the luminosity in the case of e + e - collisions. The opposite is true for e - e - collisions. In this case the luminosity is reduced by mutual defocusing, or anti-pinching. The resulting Beamstrahlung energy loss and beam-beam deflection angles as function of the vertical transverse offset are also different for both modes of operation. The dependence of these quantities with transverse beam sizes are presented for the case of e - e - collisions

This study examined the effect of two e-cigarette warning labels on college students' perceived advantages and risks of e-cigarette use, as well as students' intentions to use e-cigarettes. The company-produced e-cigarette warning label carries abundant information with small font size while the governmental warning label has only two sentences presented in large font size. The effect of both labels have not yet been examined and verified. Data were collected in October 2015 from college students at a Midwestern university. A pretest-posttest design was employed with 338 students exposed to the warning label proposed by the FDA and 328 students exposed to the label created by e-cigarette companies. Structural equation modeling analysis was implemented to examine the effect of warning labels with the analytical model grounded in the Theory of Planned Behavior. Findings showed that college students' perceived advantages of e-cigarette use were positively related to their intentions to use e-cigarettes, while perceived risks were negatively associated with their intentions. When comparing two labels, the governmental label was found to reduce college students' intentions to use e-cigarettes via increasing perceived risks of e-cigarette use (β=0.10, pe-cigarette use. The warning label currently used by e-cigarette companies showed no influence on beliefs about or intentions to use e-cigarettes. The warning label proposed by the FDA is more effective than that created by e-cigarette companies, however, has room for improvement to make a greater impact on e-cigarette use intention.

A glicemia de jejum e Hb A1C não refletem adequadamente as alterações no metabolismo do colágeno, responsáveis pelas entesopatias e tendinites nesses pacientes.

Full Text Available E-government has been considered as one approach for changing the face of government in the eyes of the citizenry. Therefore, citizens’ socialization in relation to their engagement with e-government should be explored. This study argues that citizens played a significant role in determining the success of an e-government project in the Middle Eastern country of Jordan. This paper aims to provide insight and evaluation into the factors that could influence e-government’s effective functioning in the Jordanian social community through its interaction with citizens. The study collected data from 356 Jordanian citizens via a survey, to ascertain their understanding of 10 factors that may influence their intention to use e-government services. To investigate the adoption of e-government services in depth, two departments in Jordan were selected: the Jordanian Government’s Income and Sales Tax Department (ISTD and its Driver and Vehicle Licenses Department (DVDL. The factor analysis technique was used to identify the main factors related to e-government services’ adoption. The results indicated that trust in the internet, website design, religious beliefs, internet and computer skill confidence, word of mouth, resistance to change, perceived usefulness, relative advantage and complexity are the main factors that should be considered when addressing the topic of e-government services’ adoption in Jordan. This study is different from most existing studies on e-government adoption as it empirically investigated the impact of word of mouth (WOM, wasta (favoritism, and resistance to change on e-government adoption. This study highlights the importance of considering the social cohesion of the Jordanian community when exploring factors related to e-government adoption.

Métodos: Foram avaliados, em estudo transversal, 150 crianças e adolescentes (e seus respectivos pais, divididos em três grupos: FMJ, AIJ e controles saudáveis. A mensuração e o enfrentamento da dor foram realizados por meio de instrumentos específicos. Para a avaliação da percepção da dor, desenvolveram-se três vinhetas com simulação de situações que pudessem gerar dor: aplicação de injeção, queda de bicicleta e isolamento social. Os pais e os pacientes responderam individualmente quanto à percepção da dor em cada situação. Resultados: As maiores notas de dor, os menores escores de enfrentamento da dor, as maiores notas para a percepção da dor nas vinhetas e os piores índices de qualidade de vida relacionada à saúde foram observados nos pacientes com FMJ, quando comparados aos pacientes com AIJ e aos controles. O mesmo padrão foi observado com os respectivos pais. Conclusões: Pacientes com AIJ e FMJ se comportam diferentemente em relação à percepção da dor e ao desenvolvimento de técnicas para o enfrentamento da dor. A dor deve ser avaliada sob diferentes perspectivas para um planejamento mais individualizado e efetivo do tratamento desses pacientes.

In this report, originally proposed apratoxin E (30S-7), revised apratoxin E (30R-7), and (30S)/(30R)-oxoapratoxin E (30S)-38/(30R)-38 were efficiently prepared by two synthetic methods. The chiral lactone 10, recycled from the degradation of saponin glycosides, was utilized to prepare the key nonpeptide fragment 9. Our alternative convergent assembly strategy was applied to the divergent synthesis of revised apratoxin E and its three analogues. Moreover, ring-closing metathesis (RCM) was for the first time found to be an efficient strategy for the macrocyclization of apratoxins.

Physics with e+e- Linear Colliders

International Nuclear Information System (INIS)

Barklow, Timothy L

2003-01-01

We describe the physics potential of e + e - linear colliders in this report. These machines are planned to operate in the first phase at a center-of-mass energy of 500 GeV, before being scaled up to about 1 TeV. In the second phase of the operation, a final energy of about 2 TeV is expected. The machines will allow us to perform precision tests of the heavy particles in the Standard Model, the top quark and the electroweak bosons. They are ideal facilities for exploring the properties of Higgs particles, in particular in the intermediate mass range. New vector bosons and novel matter particles in extended gauge theories can be searched for and studied thoroughly. The machines provide unique opportunities for the discovery of particles in supersymmetric extensions of the Standard Model, the spectrum of Higgs particles, the supersymmetric partners of the electroweak gauge and Higgs bosons, and of the matter particles. High precision analyses of their properties and interactions will allow for extrapolations to energy scales close to the Planck scale where gravity becomes significant. In alternative scenarios, like compositeness models, novel matter particles and interactions can be discovered and investigated in the energy range above the existing colliders up to the TeV scale. Whatever scenario is realized in Nature, the discovery potential of e + e - linear colliders and the high-precision with which the properties of particles and their interactions can be analyzed, define an exciting physics programme complementary to hadron machines

Procuro refletir sobre a forma com que o escritor se apropria de realidades sociais cotidianas, relativas à modernidade de seu tempo e à moda, e as imprime nas estratégias de criação literária por meio de fatos reais entrelaçados às suas personagens, criando no espaço ficcional traços marcadamente relevantes para se observarem essas realidades. O pano de fundo da narrativa é o Rio de Janeiro do século XIX, momento em que ocorrem a crise do Império, a abolição da escravatura e o início da República. A obra permite perceber as relações sociais e profissionais masculinas, bem como o posicionamento da mulher nessa sociedade.
Behavior of the E-E' Bonds (E, E' = S and Se) in Glutathione Disulfide and Derivatives Elucidated by Quantum Chemical Calculations with the Quantum Theory of Atoms-in-Molecules Approach.

The nature of the E-E' bonds (E, E' = S and Se) in glutathione disulfide ( 1 ) and derivatives 2 - 3 , respectively, was elucidated by applying quantum theory of atoms-in-molecules (QTAIM) dual functional analysis (QTAIM-DFA), to clarify the basic contribution of E-E' in the biological redox process, such as the glutathione peroxidase process. Five most stable conformers a - e were obtained, after applying the Monte-Carlo method then structural optimizations. In QTAIM-DFA, total electron energy densities H b ( r c ) are plotted versus H b ( r c ) - V b ( r c )/2 at bond critical points (BCPs), where V b ( r c ) are potential energy densities at BCPs. Data from the fully optimized structures correspond to the static nature. Those containing perturbed structures around the fully optimized one in the plot represent the dynamic nature of interactions. The behavior of E-E' was examined carefully. Whereas E-E' in 1a - 3e were all predicted to have the weak covalent nature of the shared shell interactions, two different types of S-S were detected in 1 , depending on the conformational properties. Contributions from the intramolecular non-covalent interactions to stabilize the conformers were evaluated. An inverse relationship was observed between the stability of a conformer and the strength of E-E' in the conformer, of which reason was discussed.

Full Text Available This research aims to rank the relative performance of tourism websites in terms of e-satisfaction, e-trust, e-quality, and e-loyalty variables. To this end, two major Iranian travel websites providing accommodation (Iran Hotel Online and tour packages (Marcopolo Corporation were chosen and their performances were evaluated based on the four above variables. This research comprises two independent surveys. The first survey administered to a sample of 155 university professors and website designers examined the relative weights of the study variables in explaining the e-performance of these websites through structural equation modeling (SEM. The results indicate that e-quality, e-loyalty, e-trust, and e-satisfaction have the strongest impact on the e-performance, respectively. The second survey examined relative weights of the e-performance based on the websites’ existing e-customers (two categories of 154 and 187 samples and also qualitative content analysis of the websites’ characteristics using fuzzy analytical hierarchical process (AHP. The findings served to inform that Marcopolo website obtained stronger weights for all four variables, compared with Iran Hotel Online, indicating its higher performance in all variables. At the end, the weight values from the SEM and AHP surveys were synthesized (0.580 and 0.418 for Marcopolo and Iran Hotel Online, respectively in order to rank the websites based on their e-performances. According to the findings, Marcopolo website outperforms its counterpart in all four variables. The current paper contributes to the literature by yielding some insights into how to benchmark websites in order to improve their e-performance based on perspectives of both customers and experts.

Omalizumab decreases IgE production in patients with allergic (IgE-mediated) asthma; PKPD analysis of a biomarker, total IgE

Science.gov (United States)

Lowe, Philip J; Renard, Didier

2011-01-01

AIM To determine whether excessive IgE production by patients with atopic allergic asthma decreases with omalizumab therapy. METHODS Omalizumab, free and total IgE data were obtained from an epidemiological study and six randomized, double-blind, placebo-controlled trials in patients with allergic asthma. The binding between omalizumab and IgE together with the production and elimination of IgE were modelled as previously, except that, in order to explain why total IgE was decreasing over a period of 5 years, the expression of IgE was allowed to change. RESULTS The prior constant IgE production model failed to converge on the data once long-term observations were included, whereas models allowing IgE production to decrease fitted. A feedback model indicated that, on average, IgE production decreased by 54% per year. This model was further developed with covariate searches indicating clinically small but statistically significant effects of age, gender, body mass index and race on some parameters. Model predictions were checked internally and externally against 3–5 year data from paediatric and adult atopic asthmatic patients and externally against extensive total IgE data from a long-duration (>1 year) phase 1 study which was not used in the model building. CONCLUSIONS A pharmacokinetic–pharmacodynamic model incorporating omalizumab–IgE binding and feedback for control of IgE production indicates that omalizumab reduces production of IgE. This raises the possibility that indefinite treatment may not be required, only for perhaps a few years. After the initial accumulation, total IgE should provide a means to monitor IgE production and guide individual treatment decisions. PMID:21392073

Its internal structure includes a rotating equatorial disk of de Sitter vacuum which has properties of a perfect conductor and ideal diamagnetic, displays superconducting behavior, supplies a particle with the finite positive electromagnetic mass related to breaking of space-time symmetry, and gives some idea about the physical origin of a minimal length in annihilation.
New neutral current effects at e+e- linear colliders

2002-01-01

Four fermion contact interaction effects in the processes e + e - → μ + μ - , b-barb and c-barc at the e + e - linear colliders with √ s = 0.5 TeV and longitudinally polarized initial beams have been studied. Presented analysis has been performed by means of new integrated observables expressed in terms of the forward (σ F ) and backward (σ B ) polarized cross sections such that they give information on individual helicity cross sections. The helicity cross sections allow to perform a general model-independent analysis of four-fermion contact interactions and obtain the corresponding constraints on their parameters. It is also shows that the sensitivity of the new polarized observables to contact interactions is quite larger than that of the conventional observables (σ, A FB , A LR , A LR,FB ) [ru

Thinopyrum chromosomes 7el1, 7el2, 7E(e), and 7E(i), homoeologous to group 7 chromosomes of common wheat (Triticum aestivum), were determined to have many useful agronomical traits for wheat improvement. To analyze the genetic relationships among the 4 Thinopyrum 7E chromosomes, the conserved orthologous set markers, genomic in situ hybridization (GISH), and meiotic chromosome pairing were used in this study. The unweighted pair-group method with arithmetical averages (UPGMA) analysis indicated that 7el1, derived from T. ponticum, and 7E(i), derived from T. intermedium, were the most closely related. 7el2, derived from T. ponticum, was relatively distant from the 7el1-7E(i) complex. While 7E(e), derived from T. elongatum, was more distantly related to 7el1, 7el2, and 7E(i). This is the first report showing that 7el1 and 7E(i) may be similar, which could be explained by the similar chromosome signal distribution revealed by GISH as well as UPGMA analysis revealed by both molecular markers and the highest frequency of meiotic pairing. The newly developed genome-specific molecular markers may be useful for marker-assisted selection of Lr19, Bdv3, and Fhblop. © 2015 S. Karger AG, Basel.

The aim of this work was to evaluate the energy balance and the sustainability in the hay production through seven years data from a Intensive System of Milk Production, located in the region of Coronel Pacheco/MG Brazil. To the energy matrix determination, the categories of direct and indirect energy were considered. The energy inputs occurred in the implanting and establishing of the crop were distributed in the years considered as useful life. The direct energy, relative to the inputs, had larger participation that the indirect one, being the percentiles found of 93.05 and 6.95, respectively. The main consumer of indirect energy was the tractor, which turns on all the implements, followed by the irrigation system. The estimated energy efficiency by the process was of 3.19. Most of the used direct energy was that derived from fossil resources, in the form of fuel (diesel). The use of organic fertilizer, of poultry litter, promoted a relative reduction in the consumption of energy originated from fertilizer derived from fossil resources. With the obtained results, it was concluded that, despite of the several sources of energy consumption, the production of alfalfa hay is sustainable and efficient in the energy conversion. (author)

Full Text Available Durante a primeira república ainda eram muitas as irmandades e ordens terceiras atuantes em Salvador e várias eram as devoções e festas promovidas pelos leigos. O calendário festivo era vasto e durante todo o ano os baianos circulavam, de barco, a pé, em bondes e elevador, entre a cidade alta e baixa, pelos diferentes distritos, arrabaldes e estações de veraneio, para louvar suas entidades sagradas. Porém, também eram muitos os empecilhos ao pleno desenvolvimento dos cortejos espetaculares. As novas tecnologias contribuíam para os deslocamentos, mas as obras urbanas modificavam os espaços de devoção. Além disso, as atividades dos fiéis recebiam críticas, novas regras e interdições do poder público e da Igreja Católica. Por meio de matérias de jornais, códigos de Posturas Municipais e de Direito Canônico, portarias e correspondências entre as associações leigas e o arcebispado, analiso as principais mudanças arquitetônicas e legislativas que incidiram na vivência religiosa.

Full Text Available A partir da perspectiva teórica dos Estudos Culturais e dos Estudos de Gênero, o artigo objetiva analisar e problematizar as maneiras como as questões de gênero e de sexualidade têm sido abordadas na Educação Básica e em cursos de formação de professores. Foram analisadas algumas situações vivenciadas pelas autoras ao longo da pesquisa: um encontro presencial com turmas de 5° ano de uma escola da rede pública do Rio Grande do Sul, para a discussão de perguntas relacionadas a gênero e sexualidade; entrevistas com as professoras regentes destas turmas; a participação em uma comissão do Programa Nacional do Livro Didático voltada para a análise de livros didáticos de Ensino Médio e, por fim, algumas atividades voltadas à formação de professores no Ensino Superior. Conclui-se que, na Escola Básica, as formas de viver/explorar o corpo e a sexualidade trabalhadas dentro da escola continuam ligadas a questões biológicas e de saúde. Professores e professoras tendem a apoiar-se nessas abordagens mais “científicas” que, de certa forma, restringem a questão da sexualidade à reprodução e reiteram a heteronormatividade. Há pequenos avanços com relação às temáticas de gênero e sexualidade nos livros didáticos analisados, mas há, também, alguns retrocessos que contribuem para a perpetuação de situações de preconceito e de exclusão. Quando instados a pensar sobre tais aspectos e a analisar criticamente como alguns materiais tradicionalmente utilizados nas salas de aula da educação básica constroem determinadas representações sexualizadas e generificadas, os professores em formação encontram, em geral, muitas dificuldades.

Full Text Available BackgroundType 2 diabetes mellitus (T2DM is associated with increased risk of malignant ventricular arrhythmias. Cardiac electrical inhomogeneity may be the leading cause of the increased arrhythmic risk in patients with T2DM. The peak and the end of the T wave (Tp-e interval and associated Tp-e/QT ratio are promising measures of ventricular repolarization indicating transmural dispersion of repolarization. The aim of this study was to assess ventricular repolarization in patients with T2DM by using Tp-e interval, Tp-e/QT ratio and Tp-e/corrected QT interval (QTc ratio.MethodsForty-three patients with T2DM and 43 healthy control subjects, matched by gender and age, were studied. All participants underwent electrocardiography (ECG recording. PR, RR and QT intervals represents the ECG intervals. These are not abbreviations. In all literature these ECG intervals are written like in this text. Tp-e intervals were measured from 12-lead ECG. Rate QTc was calculated by using the Bazett's formula. Tp-e/QT ratio and Tp-e/QTc ratio were also calculated.ResultsMean Tp-e interval was significantly prolonged in patients with T2DM compared to controls (79.4±10.3, 66.4±8.1 ms, respectively; P<0.001. We also found significantly higher values of Tp-e/QT ratio and Tp-e/QTc ratio in patients with diabetes than controls (0.21±0.03, 0.17±0.02 and 0.19±0.02, 0.16±0.02, respectively; P<0.001. There was no difference in terms of the other ECG parameters between the groups.ConclusionTp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio were prolonged in patients with T2DM. We concluded that T2DM leads to augmentation of transmural dispersion of repolarization suggesting increased risk for ventricular arrhythmogenesis.

The instantaneous wave-free ratio (iFR) is a vasodilator-free, invasive pressure wire index of the functional severity of coronary stenosis and is calculated under resting conditions. In a recent study, iFR was found to be more closely linked to coronary flow reserve (CFR) than fractional flow reserve (FFR). E/e' is a surrogate marker of left ventricular (LV) filling pressure and LV diastolic dysfunction. Coronary resting flow was found to be increased in patients with elevated E/e', and higher coronary resting flow was associated with lower CFR. Higher baseline coronary flow induces a greater loss of translesional pressure and may affect iFR. However, no reports have examined the impact of E/e' on iFR. The purpose of this study was to assess the relationship between iFR and E/e' compared with FFR. We retrospectively examined 103 consecutive patients (142 with stenosis) whose iFR, FFR, and E/e' were measured simultaneously. The mean age, LV mass index, and systolic blood pressure of patients with elevated E/e' were higher than those of patients with normal E/e'. Although no significant differences were observed in mean FFR values and % diameter stenosis, the mean iFR value in patients with elevated E/e' was significantly lower than that in patients with normal E/e'. The iFR was negatively correlated with E/e', while there was no correlation between FFR and E/e'. Multivariate analysis showed that E/e' and % diameter stenosis were independent determinants of iFR. E/e' ratio affects iFR values. Our results suggest that FFR mainly reflects the functional severity of the epicardial stenosis whereas iFR could potentially be influenced by not only epicardial stenosis but also other factors related to LV filling pressure or LV diastolic dysfunction. Further research is needed to understand the underlying mechanisms that influence the evaluation of iFR in patients with elevated E/e'. Copyright © 2017 Japanese College of Cardiology.

Para tanto, foram realizados testes de leitura com um grupo de leitores. Tais testes ajudaram a compreender como eles lidam com diferentes organizações textuais e como se comportam no decorrer do processo de leitura. A revista escolhida para análise foi a Superinteressante. Para melhor qualificar esta pesquisa algumas observações foram realizadas durante os testes com os leitores.

2018-01-01

Tobacco smoking is the most preventable cause of morbidity and mortality. In just a few short years, electronic cigarettes (e-cigarettes) have become increasingly popular, especially for younger individuals. Many people believe that e-cigarettes are safe. The inhaled aerosols of e-cigarettes contain numerous potential toxicities, some of which could be dangerous for health with long-term use. The safety of prolonged aerosol exposure is not known. The use of e-cigarettes as a harm-reduction tool at stopping tobacco smoking is not uniformly successful. E-cigarettes may be safer than tobacco products, but repeated prolonged exposure to their aerosols has its own considerable potential risk. The long-term health consequences of their use remain to be established. Physicians should vigorously discourage the use of e-cigarettes and tobacco products, with special emphasis on abstinence for younger people and during pregnancy or lactation.
