1. Shear wave elastography in early diabetic kidney disease
SUMMARY OBJECTIVE: This study aimed to analyze the kidneys among the subjects with early stages of type 2 diabetic kidney disease by shear wave elastography quantitatively. METHODS: A total of 108 patients with type 2 diabetic kidney disease and 17 control subjects were enrolled. According to the estimated glomerular filtration rate and urinary albumin-to-

2. Rheological Parameters of Shear-Thickening Fluids Using an Experimental Design
Abstract: The influence of important factors related to fluid preparation on shear-thickening fluids (STF) is not well explored in literature. Thus, this paper aimed at analyzing the statistical significance of experimental conditions, such as fumed silica concentration (Cs), stirring time (tst), stirring speed (Sst) and sonication time (tso ), on the rheolo

3. 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

4. RHEOLOGICAL BEHAVIOR OF A SILVER AQUEOUS NANOFLUID STABILIZED WITH AMINOSILANE-BASED SURFACTANT UNDER CONFINED FLOW
ABSTRACT The rheological behavior of an aqueous suspension of silver nanoparticles stabilized with aminosilane-based surfactant flowing under confinement was investigated. Three stability levels were defined based on the zeta potential: high (41.73 mV, pH 4.3), medium (10.44 mV, pH 7.4), and low (0.74 mV, pH 8.6). Furthermore, the preliminary investigation s

7. 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

8. 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

9. 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

10. Micro-mechanical numerical analyses on the effect of stress state on ductile damage under dynamic loading conditions
Abstract The paper deals with the effect of stress state on the dynamic damage behavior of ductile materials. The rate- and temperature-dependent continuum damage model has been enhanced to take into account the influence of the stress triaxiality and the Lode parameter on damage condition and on rate equations of damage strains. Different branches of these

11. Wheat flour and gum cordia composite system: pasting, rheology and texture studies
Abstract Native and acetylated freeze-dried gum cordia (GC) was replaced at 0, 3, 5 and 10% (w/w) of wheat flour, and their pasting and rheological properties were studied. The pasting data indicated a significant (p≤0.05) increase in peak and final viscosities of blends: especially at higher GC concentrations. The shearing profiles signified an increase
