Perfil metabólico de caprinos sob restrição alimentar e realimentação
No full textThe objective of this work was to evaluate the effects of dietary restriction and feedback on
goat metabolic profile. In the experiment were used 25 castrated goats, separated in collective
stalls. The experimental period was 114 days, comprised of a 30-day adaptation, where they
received large and concentrated food, as well as free water, 42 days of food restriction and 42
days of feedback. The animals were divided into 5 groups of 5 (G1, G2, G3, G4 and G5) and
submitted to isoprotein / hypoenergetic food restriction (40% - G1); isoenergetic /
hypoprotein (20% - G2) isoprotein / hypoenergetic (20% - G3); isoenergetic / hypoproteic
(40% - G4) and hypoproteic / hypoenergetic (30% - G5), later fed on hyperproteic and
hyperenergetic diets. Blood samples were collected on days 0, 1, 3, 7, 14, 21, 28, 35 and 42 of
restriction and 0, 7, 14, 21, 28, 35 and 42 of feedback. Hematological analysis included total
red blood cell count, global leukocyte count, hematocrit and plasma proteins. For metabolic
profile evaluation, the energetic variables analyzed were: glucose, cholesterol and
triglycerides; whereas protein variables were: total protein, urea, albumin, creatinine,
globulins, and enzymatic action metabolites creatine kinase (CK), aspartate transaminase
(AST) and gamma glutamyltrasferase (GGT). During the restriction period, glucose showed
no differences between treatments. However, a significant increase (p <0.05) was observed
between times T0 and T1. Most of the values obtained for cholesterol remained within the
reference values and only groups G3, G4 and G5 differed between times. Regarding
triglycerides, there was a difference (p <0.05) between G4 and G5 in T7. In T42, groups G2
and G3 differed from each other, as did treatments G3 and G5. For the values of urea the
groups G2 and G4 presented the lowest values among all, during the experiment. For total
proteins, G5 treatment showed a decrease (p <0.05) in serum values after the 21st day of the
experiment. The metabolic changes to which the animals underwent in this study were not
sufficient to cause liver damage in them, according to AST, GGT values. In the feedback
phase, even after the energy and protein level readjustment, there was no return to normal
cholesterol levels in treatments G4 and G5. G2 and G5 presented means below the reference
values for the glucose variable. At time T1, group G3 presented lower concentrations of urea.
Albumin returned to normal values after 28 days, and remained so until the end. CK levels
were normalized from T1, except for G4, whose normalization occurred at T7. Among the
analyzed variables, glucose, total protein and albumin were not efficient to detect the
proposed deficiencies in restrictive diets, while cholesterol, triglycerides, urea and globulins
allowed the identification of short- and medium-term protein-energy deficiencies. . In some groups, the feedback promoted the reestablishment of the levels of some protein and energy
metabolites. The groups maintained on hypoproteic or hypoproteic and hypoenergetic diets
presented greater difficulties for such reestablishment.O objetivo do trabalho foi avaliar os efeitos da restrição alimentar e da realimentação sobre o
perfil metabólico de caprinos. No experimento, foram utilizados 25 caprinos castrados,
separados em baias coletivas. O período experimental foi de 114 dias, compreendido por uma
adaptação de 30 dias, onde receberam alimento volumoso e concentrado, além de água à
vontade, 42 dias de restrição alimentar e 42 dias de realimentação. Os animais foram
divididos em 5 grupos de 5 (G1, G2, G3, G4 e G5) e submetidos a restrição alimentar
isoproteica / hipoenergética (40% - G1); isoenergética / hipoproteica (20% - G2) isoproteica /
hipoenergética (20% - G3); isoenergética / hipoproteica (40% - G4) e hipoproteica /
hipoenergética (30% - G5), posteriormente realimentados com dietas hiperproteicas e
hiperenergeticas. As amostras de sangue foram coletadas nos dias 0, 1, 3, 7, 14, 21, 28, 35 e
42, de restrição e 0, 7, 14, 21, 28, 35 e 42 da realimentação. Na análise hematológica foram
feitas contagem total de hemácias, contagem global de leucócitos, hematócrito e proteínas
plasmáticas. Já para avaliação do perfil metabólico dos animais, as variáveis energéticas
analisadas foram: glicose, colesterol e triglicerídeos; enquanto que as variáveis proteicas
foram: proteína total, ureia, albumina, creatinina, globulinas, e metabolitos de ação enzimática
creatina quinase (CK), aspartato transaminase (AST) e gama glutamiltrasferase (GGT).
Durante o período de restrição, a glicose não apresentou diferenças entre os tratamentos. No
entanto, observou-se aumento significativo (p<0,05) entre os tempos T0 e T1. Grande parte
dos valores obtidos para o colesterol, se manteve dentro dos valores de referência e apenas os
grupos G3, G4 e G5 diferiram entres os tempos. Com relação ao triglicerídeos, observou-se
diferença (p<0,05) entre G4 e G5 no T7. Já no T42, os grupos G2 e G3 diferiram entre si,
assim como os tratamentos G3 e G5. Para os valores de ureia os grupos G2 e G4 apresentaram
os menores valores entre todos, ao longo do experimento. Para as proteínas totais, o
tratamento G5, apresentou diminuição (p<0,05) dos valores séricos, após o 21º dia do
experimento. As alterações metabólicas aos quais os animais foram submetidos neste estudo,
não foram suficientes para causar lesão hepática nos mesmos, de acordo com os valores de
AST, GGT. Já na fase de realimentação, mesmo após a readequação do nível de energia e
proteína, não houve retorno aos níveis normais de colesterol, nos tratamentos G4 e G5. O G2
e G5 apresentaram médias abaixo dos valores de referência, para a variável glicose. No
momento T1, o grupo G3 apresentou menores concentrações de ureia. A albumina voltou aos
valores normais após 28 dias, e assim permaneceu até o fim. Já os níveis de CK foram
normalizados a partir do T1, com exceção do G4, cuja a normalização se deu no T7. Dentre as
variáveis analisadas, a glicose, a proteína total e albumina, não se mostraram eficientes para detectar as carências propostas nas dietas restritivas, enquanto que o colesterol, triglicerídeos,
ureia e globulinas permitiram a identificação de carências proteico-energéticas de curto e
médio prazo. A realimentação promoveu, em alguns grupos, o reestabelecimento dos níveis
de alguns metabolitos de caráter proteicos e energéticos. Os grupos mantidos com dietas
hipoproteicas ou hipoproteicas e hipoenergéticas apresentaram maiores dificuldades para tal
reestabelecimento.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPE
Efeito da compartimentalização de um reservatório do semiárido brasileiro sobre a condição corporal de peixes
No full textO ecossistema de reservatórios, devido a fatores biológicos, químicos e físicos, pode
apresentar uma heterogeneidade entre suas regiões fluvial e lacustre. É esperado que essa
diferença tenha um reflexo sobre a condição corporal dos peixes, de acordo com o
compartimento do reservatório que eles estejam. Essas diferenças podem ser observadas pelo
uso de índices matemáticos como relação peso-comprimento e fator de condição. O objetivo
deste trabalho foi analisar se o gradiente longitudinal de um reservatório afeta na condição
corporal de cinco espécies de peixes de guildas tróficas distintas. O estudo foi realizado no
reservatório de Santa Cruz, que fica localizado no munícipio de Apodi/RN, Brasil. Os peixes
foram coletados ao longo de oito pontos amostrais, os quais foram divididos em duas zonas,
lacustre (pontos de 1 a 6) e fluvial (pontos de 7 e 8). As coletas ocorreram trimestralmente
entre fevereiro de 2010 e novembro de 2017, com auxílio de rede de espera, com malhas
variando entre 12 a 70mm entre nós adjacentes, expostas por 12h na água no período noturno.
A condição corporal foi avaliada através do uso do Fator de Condição Relativo (Kn). Foram
avaliados 6.607 indivíduos. As relações peso-comprimento das espécies Hoplias malabaricus,
Hypostomus pusarum, Leporinus piau não apresentaram diferença significativa entre região
fluvial e lacustre, ao contrário das espécies Plagioscion squamosissimus e Triportheus
signatus que apresentaram diferença significativa. O fator de condição de todas as espécies
não apresentou diferença significativa entre os compartimentos lacustre e fluvial, com o valor
de Kn superior a um para todas as espécies, em ambas as regiões do reservatório. Para todas
as espécies estudadas, a compartimentalização presente no reservatório de Santa Cruz-RN não
exerceu influência sobre a condição corporal dos peixes.Trabalho não financiado por agência de fomento, ou autofinanciad
Automação do dimensionamento estrutural de fundações – sapatas e blocos
No full textThe foundations are responsible for transmitting all the loads of the superstructure of a building to the ground, these can be classified as being shallow or deep. Shallow foundations are elements in which the load is transmitted to the ground, predominantly by the distributed pressure under the base of the Foundation. The deep foundations are elements that transmit the load to the ground by the base, by your side or by a combination of the two. This work is an applied research, where the author offers a solution for the design and detailing of structural shallow foundations. Has as its objective the development of a program able to size and detail shallow Foundation of type shoes and Foundation blocks, as well as calculating the permissible load capacity of the soil and the repression suffered by the same immediately. For this, you will use the Excel software. Initially searches were carried out in order to select and understand the main and most reliable methods of calculations used. From that, they were inserted coefficients and parameters needed for the calculations in spreadsheets. Subsequently, the automation of the calculations for the design of structural elements reliably. The results calculated by the program were compared to examples from literature and other structural calculation software, showing errors between 5 and 10%, thus, reliability and safety for users.As fundações são responsáveis por transmitir todas as cargas da superestrutura de uma edificação para o solo, estas podem ser classificadas como sendo rasas ou profundas. Fundações rasas são elementos em que seu assentamento é feito em pequenas profundidades. Já as fundações profundas são elementos assentadas a grandes profundidades. Este trabalho trata de uma pesquisa aplicada, onde o autor oferece uma solução para o dimensionamento e detalhamento de fundações estruturais rasas.

A partir disso, foram inseridos coeficientes e parâmetros necessários para os cálculos em planilhas auxiliares. Posteriormente, foi realizado a automação dos cálculos para o dimensionamento dos elementos estruturais de forma confiável. Os resultados calculados pelo programa, foram comparados a exemplos da literatura e a outros softwares de cálculo estrutural, apresentando diferenças entre 5 e 10%, passando dessa forma, confiabilidade e segurança para os usuários.Trabalho não financiado por agência de fomento, ou autofinanciad
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Excitation System Technologies for Wound-Field Synchronous Machines: Survey of Solutions and Evolving Trends
No full textWound-field synchronous machines (WFSMs) are included in the majority of large power generating units and special high-power motor drives, due to their high efficiency, flexible field excitation and intrinsic flux weakening capability. Moreover, they are employed in a wide range of high-end solutions in the low-to-medium power range. This contribution presents a comprehensive survey of classical and modern methods and technologies for excitation systems (ESs) of WFSMs. The work covers the fundamental theory, typical de-excitation methods and all the modern excitation equipment topologies in detail. It also includes a description of the state-of-the-art and the latest trends in the ESs of wound-field synchronous motors and generators. The purpose of the paper is to provide a useful and up-to-date reference for practitioners and researchers in the field

Description Body short and cylindrical, usually widest at midthorax (Fig. 6 C), reddish in life, white after fixation. Holotype complete, with 47 chaetigers, 5 mm in length by 0.5 mm in width, at widest point of thorax, but longer incomplete specimens were observed and included in type series (see above). Prostomium distally expanded, with up to 11 cylindrical tentacles (Figs. 5 A, 6 A–G), longest reaching to segment 17. Laterally, basal part of prostomium with up to 4 small and frequently nearly inconspicuous eyespots (Fig. 5 A). Lips densely ciliated around mouth, upper lip short and rounded, lower lip small, restricted to oral area and frequently swollen (Fig. 6 C–G). Peristomium continuing laterally beyond lower lip for short extension, with conspicuous ciliation at border with prostomium (Fig. 6 D–F). Segment 1 dorsally short, ventrally expanded below lower lip (Fig. 6 A–G); segment 2 ventrally protruding (Fig. 6 C–G); segments 2–4 progressively longer (Fig. 6 A–B, F). Segments 1–4 progressively more inflated dorsally (Fig. 6 A–B, D, F). Distinct ventral shields from segment 2 until end of thorax, followed by midventral stripe (Fig. 6 C, G) extending until pygidium. Notopodia from segment 4 (Figs. 5 A, 6 A–D, F–G), extending for 14 segments. On segments 4–10, chaetae on anterior row of notochaetae as thin bladed, strongly serrated capillaries (Figs. 5 C, 7 A–B) and chateae on posterior row of notochaetae as slightly geniculate, limbate capillaries, with limbation ending subdistally and hirsute alimbate tip, with one lateral row of fine hairs (Figs. 5 B, 7 A, C–D). From segment 11 until end of thorax, chaetae on anterior row of notochaetae as on anterior chaetigers, but with broader bases and stouter teeth, and chaetae on posterior row of notochaetae as medially limbate, distally finely serrated capillaries (Figs. 5 F–G, 7 E –H). Neuropodia present from segment 5, glandular and sessile, slightly elevated from body wall throughout (Figs. 5 A, 6 C–D, F–I), with internal shafts attached to uncini by ligaments on abdominal segments. Uncini avicular, with short triangular heel and developed prow, dorsal button far from anterior margin of uncini, at about midlength between base of main fang and end of prow (Fig. 5 D–E); uncini with about 5 irregular rows of secondary teeth above main fang (Figs. 5 D–E, 8 A–H). Uncini arranged in double rows from segments 11–20, three segments after cessation of notopodia (Fig. 6 C, G–H); rows well separated (Fig. 8 C), but uncini from both rows with prows aligned. Nephridial papillae ventral to notopodia, or between notopodia and neuropodia, on segments 3–8 (Fig. 6 I). Pygidium crenulated, without anal papillae. Remarks Phisidia is a conservative genus, in which most characters usually used to distinguish between species of other genera of terebellines are fixed between species. Species of Phisidia usually live among algae and similar substrata, from shallow to deep waters (Table 1). Seven species of this genus have been described so far and an eighth one, from New Zealand, will be described soon (Glasby et al. in prep.) and is treated here as Phisidia sp. The most important characters distinguishing these species are the presence and number of prostomial eyespots, the number of rows of secondary teeth above uncinial main fang, the number of segments with uncini arranged in double rows and the number of pairs of notopodia. The characteristics of each species of Phisidia are listed in Table 1. Phisidia rubra sp. nov. is similar to P. echuca, P. sagamica, P. sanctaemariae and P. sp., as all have uncini arranged in double rows for 10 segments, on segments 11–20. In contrast, the known species of Phisidia with different number of segments with uncini arranged in double rows are P. oculata, which, according to the original description, has uncini arranged in double rows on segments 11 to 34 (24 segments), P. castanea, with uncini in double rows for 9 segments, and P. rubrolineata HartmannSchröder and Rosenfeldt, 1989 and P. a u re a, both latter species with uncini arranged in double rows for 910 segments. In addition to the number of segments on which uncini are arranged in double rows, P. aurea differs from P. rubra sp. nov. in being a larger species, without eyespots, with only 13 pairs of notopodia and with uncini more heavily crested, with 7 rows of secondary teeth (Table 1). P. rubrolineata also lacks eyespots, is a larger species and has uncini more heavily crested than P. rubra sp. nov., with 6 rows of secondary teeth (Table 1). In addition, it differs from P. rubra sp. nov. in having ventral shields starting from segment 5 and body pigmentation as one reddish brown longitudinal band at each lateral of the body, starting from the penultimate thoracic chaetiger and extending through the abdomen. Similarly, P. castanea differs from P. rubra sp. nov. in being a larger species and having 16 pairs of notopodia (Table 1). In addition, uncini of P. castanea have 3 rows of secondary teeth and prow and heel both distally rounded, instead of triangular and distally sharp, as in all other species of the genus. Finally, P. castanea has reddish brown pigmentation dorsally on segment 1 and on the posterior borders of segments 2–5, and ventrally on segment 2. Among the species of Phisidia with uncini arranged in double rows on segments 11–20, P. echuca is distinguished from P. r u b r a sp. nov. for being a considerably larger species, for not having prostomial eyespots and for having uncini with four rows of secondary teeth (Table 1). Phisidia sagamica was originally described in German (Hessle 1917) and, most probably because of problems of translation, some of its characters seem to have been misinterpreted. For example, Hessle (1917) said: “… Die drei ersten Paare Hakenborstenchaetopodien hinter den Haarborsten sind zweireihig, die folgenden sind einreihig…”, meaning this species has uncini arranged in double rows for three chaetigers after the end of notochaetae, thereafter in single rows. This was interpreted by subsequent authors (e. g., Southward 1956, Hutchings and Glasby 1988) as this species only having uncini in double rows for three segments, what would be very unusual for a terebelline. In our opinion, this sentence means this species has uncini in double rows until three segments after the end of notopodia, meaning segment 20, exactly as in P. a u re a, P. echuca, P. sanctaemariae and P. r u b r a sp. nov. It is unclear, however, from which segment uncini start being arranged in double rows and so it is not possible to count the number of segments with such an arrangement of uncini. In regards to eyespots, Hessle (1917) said P. sagamica has some developed eyespots, but it is unclear how many eyespots it has and also what the author means by “developed”. Anyway, P. sagamica has 4 rows of secondary teeth above the uncinial main fang, differing from P. rubra n. sp. in this respect, and its typelocality is in Japan, far from Brazil (Table 1). Phisidia sanctaemariae differs from P. rubra sp. nov., in lacking eyespots and having 16 pairs of notopodia and 7 rows of secondary teeth above the uncinial main fang (Table 1). Finally, P. sp. from New Zealand differs from P. rubra sp. nov. in having many more eyespots, which form a continuous row across the prostomium, and in having a different number of rows of secondary teeth above the main fang of uncini, 4–5 rows on the anterior thoracic uncini, 3 rows on the midthoracic uncini and about 7 rows on the abdominal uncini.Published as part of Nogueira, João Miguel De Matos & Alves, Tarsila Montrezoro, 2006, Two new terebellid polychaetes (Polychaeta: Terebellidae) from the state of São Paulo, southeastern Brazil, pp. 31-54 in Zootaxa 1205 on pages 44-52, DOI: 10.5281/zenodo.17236

Copyright: Copyright 2021 Elsevier B.V., All rights reserved.This paper is concerned with the qualitative analysis of solutions to the following class of quasilinear problems {-ΔΦu=f(x,u)inΩ,u=0on∂Ω,where ΔΦu=div(φ(x,|∇u|)∇u) and Φ(x,t)=∫0|t|φ(x,s)sds is a generalized N-function. We assume that Ω ⊂ RN is a smooth bounded domain that contains two open regions Ω N, Ω p with Ω ¯ N∩ Ω ¯ p= ∅. The features of this paper are that - Δ Φu behaves like - Δ Nu on Ω N and - Δ pu on Ω p, and that the growth of f: Ω × R→ R is like that of eα|t|NN-1 on Ω N and as |t|p∗-2t on Ω p when |t| is large enough. The main result establishes the existence of solutions in a suitable Musielak–Sobolev space in the case of high perturbations with respect to the values of a positive parameter.Peer reviewe
First observation of Bs → J/ψf0(980) decays
No full textUsing data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively
