Contribuição ao estudo dos elementos vasculares, arteriais e venosos do hilo renal em suínos Sus scrofa domestica - Linnaeus - 1758) da raça LargeWhite

Estudou-se, em 30 pares de rins de suínos da raça Large White, 15 machos e 15 fêmeas, com aproximadamente quatro meses de idade, procedentes do Matadouro e Frigorífico "Eder", em Itapecerica da Serra, Estado de São Paulo, a distribuição arterial e venosa do hilo deste órgão, mediante disseccão dos elementos vasculares do pedículo renal, após a fixação do material em solução aquosa de formol a 10,0%. Nestes animais, a artéria renal direita fornece de seis (10,0%) a vinte (3,3%) ramos, com maior frequência de dez (20,0%) e a esquerda de quatro (3,3%) a dezoito (3,3%), com maior incidência de dez(16,7%) e demonstrou uma maior concentração no quadrante craniodorsal, seguido dos quadrantes cranioventral, caudoventral e caudodorsal. No que tange ao número de raízes venosas, a veia renal direita apresenta uma variação de uma (10,0%) a cinco (33,8%) raízes, com maior frequência de cinco (33,8%),a esquerda de duas (13,3%) e sete (3,3%), com maior concentração de três e quatro (53,4%), situadas com maior incidência no quadrante cranioventral, seguido dos quadrantes caudoventral, craniodorsal ecaudodorsal. Quanto à situação global, os ramos das artérias renais direita e esquerda se apresentam em maior número de vezes preponderantemente periféricos(43,3%), enquanto as raízes venosas se mostram exclusivamente periféricas (16,7%). Há igualdade no número de ramos das artérias renais e raízes das veias renais, direitas e esquerdas, apenas 1 vez (3,3%), com distribuião desigual nos quadrantes. Não existem diferenças estatisticamente significantes quanto ao sexo.

After fixing the material in water solution of formol at 10.0% we dissected the vascular elements of the renal pedicle. In these animals the right renal artery supplies from six(10.0%) to twenty (3.3%) branches, generally with ten(20.0%) and the left from four (3.3%) to eighteen (3.3%) showing a greater indice of ten (16.7%). The greatest concentration being on the craniodorsal quadrant, following the cranioventral, caudoventral and caudodorsal quadrants. Concerning the venous roots, the right renal vein shows a variation from one(10.0%) to five (33.8%) roots, generally with five(33.8%) and left from two (13.3%) to seven (3.3%) with greater concentration of (26.7%) localized with greater frequency in the cranioventral quadrant followed by the caudoventral, craniodorsal and caudodorsal quadrants. Referring to the general situation, of the alone mentioned, the branches of the right and left arteries appear a greater number of times on the outer side (43.3%) while the venous root shows exclusively on the outer side (16.7%). There is an equal number of renal arteries and veins branches, right and left, once (3.3%) with a unequal distribution in the quadrants. There is no significant statistic difference between sexes

The crude glycerin reduces losses fermentative and improves the nutritional value of marandu grass silage in a semiarid region / A glicerina bruta reduz perdas fermentativas e melhora o valor nutricional da silagem de capim marandu em uma região semiárida

The ensiling of marandu grass at the recommended time of management results in low dry matter (DM) content and nutritional value, but the addition of crude glycerin can compensate for these deficits if used during ensiling. Thus, the aim of this study was to evaluate the best level of inclusion of crude glycerin that can improve fermentation and the nutritional value of silages prepared with Urochloa brizantha cv. Marandu. The treatments consisted of five levels of inclusion of crude glycerin (0, 7.5, 15, 22.5, 30% of fresh forage) during ensiling of marandu grass with eight replications following the completely randomized design. For the evaluation of ruminal kinetics, four crossbred steers were used, cannulated in the rumen, following a randomized block design in a split plot scheme. For the percentage unit of inclusion of glycerin, there was a linear reduction of 0.34% in gas losses and increase of 0.45% and 0.55% in the recovery of DM (P <0.01) and in the DM content (P <0.01), respectively. The inclusion of up to 22.5% of crude glycerin in the silage of marandu grass is recommended to reduce losses during fermentation and improve the recovery of dry matter and the nutritional value of silage

Search for pair-produced long-lived neutral particles decaying to jets in the ATLAS hadronic calorimeter in ppcollisions at √s=8TeV

The ATLAS detector at the Large Hadron Collider at CERN is used to search for the decay of a scalar boson to a pair of long-lived particles, neutral under the Standard Model gauge group, in 20.3fb−1of data collected in proton–proton collisions at √s=8TeV. This search is sensitive to long-lived particles that decay to Standard Model particles producing jets at the outer edge of the ATLAS electromagnetic calorimeter or inside the hadronic calorimeter. No significant excess of events is observed. Limits are reported on the product of the scalar boson production cross section times branching ratio into long-lived neutral particles as a function of the proper lifetime of the particles. Limits are reported for boson masses from 100 GeVto 900 GeV, and a long-lived neutral particle mass from 10 GeVto 150 GeV

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at s√=8 TeV with the ATLAS detector

The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1fb−1 of proton–proton collision data at √s = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via t˜→tχ˜01 or t˜→ bχ˜±1 →bW(∗)χ˜01 , where χ˜01 (χ˜±1 ) denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and neutralino masses and as a function of the branching fraction of t˜ → tχ˜01 . For a branching fraction of 100%, top squark masses in the range 270–645 GeV are excluded for χ˜01 masses below 30 GeV. For a branching fraction of 50% to either t˜ → tχ˜01 or t˜ → bχ˜±1 , and assuming the χ˜±1 mass to be twice the χ˜01 mass, top squark masses in the range 250–550 GeV are excluded for χ˜01 masses below 60 GeV

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Measurement of χ c1 and χ c2 production with s√ = 7 TeV pp collisions at ATLAS

The prompt and non-prompt production cross-sections for the χ c1 and χ c2 charmonium states are measured in pp collisions at s√ = 7 TeV with the ATLAS detector at the LHC using 4.5 fb−1 of integrated luminosity. The χ c states are reconstructed through the radiative decay χ c → J/ψγ (with J/ψ → μ + μ −) where photons are reconstructed from γ → e + e − conversions. The production rate of the χ c2 state relative to the χ c1 state is measured for prompt and non-prompt χ c as a function of J/ψ transverse momentum. The prompt χ c cross-sections are combined with existing measurements of prompt J/ψ production to derive the fraction of prompt J/ψ produced in feed-down from χ c decays. The fractions of χ c1 and χ c2 produced in b-hadron decays are also measured

Measurements of fiducial and differential cross sections for Higgs boson production in the diphoton decay channel at s√=8 TeV with ATLAS

Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of s√=8 TeV. The analysis is performed in the H → γγ decay channel using 20.3 fb−1 of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assuming that the width of the resonance is much smaller than the experimental resolution. The signal yields are corrected for the effects of detector inefficiency and resolution. The pp → H → γγ fiducial cross section is measured to be 43.2 ±9.4(stat.) − 2.9 + 3.2 (syst.) ±1.2(lumi)fb for a Higgs boson of mass 125.4GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity less than 2.37. Four additional fiducial cross sections and two cross-section limits are presented in phase space regions that test the theoretical modelling of different Higgs boson production mechanisms, or are sensitive to physics beyond the Standard Model. Differential cross sections are also presented, as a function of variables related to the diphoton kinematics and the jet activity produced in the Higgs boson events. The observed spectra are statistically limited but broadly in line with the theoretical expectations
