13. Echotextural characteristics of the mammary gland during early lactation in two breeds of sheep varying in milk yields
Abstract The main goal of this preliminary study was to determine and compare ultrasonographic characteristics of the mammary gland in two genotypes of ewes varying in milk productivity at 2, 3 and 4 weeks after lambing. Ultrasonographic images of the udder were obtained using the 5.0- and 7.5-MHz transducers, in axial and coronal planes, in four low milk-yi

16. [PROVISIONAL] Resistance mutations of NS3 and NS5b in treatment-naïve patients infected with Hepatitis C virus in Santa Catarina and Rio Grande do Sul States, Brazil
Abstract Hepatitis C virus (HCV) infection is a worldwide health problem. Nowadays, direct-acting antiviral agents (DAAs) are the main treatment; however, the high level of variability of HCV lead to development of resistance-associated variants (RAVs). Thus, look into the RAVs among infected patients is an important tool for monitoring the efficacy of the t

17. Study of behavior alloy Ti and 316L in to simulated body fluid by electrochemical techniques
ABSTRACT In this work, Ti-316L stainless steel was produced, and its electrochemical behavior was characterized. Ti-steel alloys were produced using an induction furnace, by mixing commercial Ti and 316L stainless steel. X-ray diffraction analyses showed the presence of both the materials, Ti and 316L, in the samples produced. The elemental composition of th

18. Corrosion Behavior of 316L and Alloy 182 Dissimilar Weld Joint with Post-Weld Heat Treatment
ABSTRACT Austenitic stainless steel and nickel-base alloys welds are widely used in nuclear reactor components, plants of energy generation, chemical, and petrochemical industries, due to their high corrosion resistance. The post weld heat treatments (PWHT) are generally applied to welding in order to relieve the welding residual stress. The aim of this work

20. Depression and quality of life in older adults on hemodialysis
Objective: Depression is highly prevalent in hemodialysis patients, but few studies have evaluated older hemodialysis patients. The aim of this study was to evaluate the prevalence of depression, its associated factors and its impact on quality of life in an older population on hemodialysis. Methods: This was a cross-sectional study including 173 hemodialy

21. Influence of the Gas Pressure of Plasma Nitriding on the Structural, Mechanical and Tribological Surface Properties of AISI 316L
In this paper, the influence of gas nitriding (80% H2-20% N2) pressure (between 3 and 7 Torr) on the modification of surface properties of AISI 316L stainless steel is examined. The structural, mechanical, tribological and electrochemical properties of the layer produced in disk samples were studied. The samples’ characteristics were determined by scanning

24. Obtainment and Characterization of a Silicon alkoxides-based Coating Applied to a Substrate of Stainless Steel 316L for Use in Biomaterials
The silicon alkoxides-based coating is an alternative to control the release of cytotoxic ions through metal implants. This study evaluated the influence of the number of layers of a hybrid coating on the surface of austenitic stainless steel AISI 316L on the corrosion resistance. This coating was produced from the precursors of silicon alkoxides 3-(trimetho
