13. Shear strength analysis of slabs without transverse reinforcement under concentrated loads according to ABNT NBR 6118:2014
Resumo A solicitação por cargas parcialmente distribuídas em lajes sem armadura transversal, frequente em tabuleiros de pontes, resulta na propagação horizontal da força cortante em direção aos apoios, situação na qual nem toda a largura da laje é mobilizada. Por esta razão, os modelos de resistência à força cortante de vigas e de resistência

14. Sobre o surgimento das equações de Maxwell
Resumo Em seu Sobre linhas de força físicas Maxwell apresentou a primeira versão de suas equações eletromagnéticas, quando a luz foi então encarada como distúrbio cisalhante em um éter fluido e elástico. No presente artigo procuro discutir os detalhes deste modelo mecânico que serviu de trampolim para Maxwell propor a teoria eletromagnética da lu

15. Carcass characteristics and fatty acid profile of Santa Inês lamb fed banana leftovers
ABSTRACT: The use of new feed resources, particularly local agroindustrial byproducts, such as banana, may be an option for replacing those traditionally used for sheep feed to reduce production costs. Thus, the aim of this study was to evaluate the dietary effects of replacing corn bran with banana leftovers on performance, carcass, non-carcass components,

16. Performance and carcass characteristics of broilers fed whole corn germ
ABSTRACT The objective of this study was to evaluate the effect of including whole corn germ (WCG) on the performance; diet metabolizability; yields of carcass, cuts, and offal; and quality of meat of broilers. A total of 648 chicks were assigned to six treatments in a completely randomized design with six replicates, with 18 birds in each. Treatments consis

17. Influência do material da ferramenta de corte sobre a usinabilidade do aço ABNT 4340 no torneamento
RESUMO No presente trabalho procurou-se compreender os fenômenos associados à usinagem do aço ABNT 4340 utilizando ferramentas de corte de metal duro e cermet, ambas com geometria do quebra-cavaco para usinagem leve (LP) e média (MP). Nesse sentido, analisou-se a influência da variação do avanço, quebracavaco e o material da ferramenta de corte nos p

18. Lairage time effect on meat quality in Hereford steers in rangeland conditions
ABSTRACT This study evaluated lairage time effects on carcass and meat quality traits of Hereford steers. Thirty Hereford steers fed on pasture were assigned to two treatments according to lairage time: 3 h (n = 15) and 12 h (n = 15). Individual temperament was assessed using crush score and flight speed. pH decline, glycogen content, meat color, and shear f

19. Delayed carcass chilling improves tenderness of the beef gluteus medius muscle
Resumo: O objetivo deste trabalho foi avaliar os efeitos de uma taxa de resfriamento mais lenta sobre as características físico-químicas da alcatra (M. gluteus medius) de touros F1 Angus x Nelore, maturada por 14 dias. Carcaças leves e magras (n = 30) foram divididas em meias carcaças e selecionadas para controle (2°C por 24 horas) e tratamento (10°C

20. Seismic Evaluation of Horizontally Curved Bridges Subjected to Near-Field Ground Motions
Abstract Horizontally curved bridges have more complex seismic behavior than straight bridges and have been more vulnerable to earthquakes. The present study aimed to evaluate the seismic response of concrete bridges with straight and arched box girder decks in isolated and non-isolated states. The results indicated that increasing the curvature of the non-i

21. Comparative analysis among standards of the area calculation of transversal reinforcement on reinforced concrete beams of high resistance subjected by shear force
Resumo Concretos de alta resistência (CAR) correspondem a uma resistência à compressão característica compreendida entre 55 e 90 MPa. Com a possibilidade crescente da utilização de CAR, faz-se necessária a realização de estudos que abordem os tratamentos normativos usuais acerca do dimensionamento de elementos por ele constituídos, especificamente

22. The effect of cooking methods on some quality characteristics of gluteus medius
Abstract In this research, the effects of cooking by convection oven and cooking by sous-vide method on the physicochemical, textural, sensorial and microbiological of gluteus medius cuts were investigated. For the sous-vide method, the meat was vacuumed sealed in special packaging material (Mylar®Cook) before being stored at + 1 °C for 0, 15, and 30 days

23. Performance and carcass characteristics of goats fed crude glycerin in the feedlot and during pre-slaughter lairage
ABSTRACT This study evaluated the effects of crude glycerin (CG) supplied separately from the other dietary ingredients to goats during the feedlot and in the pre-slaughter lairage on the nutrient intake, performance, behavioral and physiological parameters, carcass characteristics, and meat quality. Twenty-eight uncastrated male goats from a cross between t

24. Performance and carcass characteristics of lambs fed a solution of crude glycerin during feedlot and pre-slaughter lairage
ABSTRACT The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of crude glycerin plus water (100 g kg−1 of dry matter) (GLY) during feedlot and pre-slaughter lairage. Data were analyzed as a 2 × 2 factorial (GLY available or not in feedlot and GLY available or not in the slaughterhouse). We ev
