1. Efeito de fibras sintéticas nas propriedades de ligantes e concretos asfálticos
The asphalt cement plays a major role in hot mix asphalts (HMA) by bonding the mineral aggregates and conferring impermeability. Despite the relatively small percentage of asphalt cement in hot mixes, the mechanical properties of asphalt layers are highly dependent on the quality of the binder. The physical and rheological properties of asphalt binders can b

2. Preparation of organically modified silica from rice husk with capacity to sorption of metallic ions. / Preparação de sílica organofuncionalizada a partir de casca de arroz, com capacidade adsorvente de íons metálicos.
This thesis presents the obtainment of silica xerogel by rice husk charcoal and its surface modification using an organic ligand type Schiff-base. The purpose of this agro-industrial residue utilization is the production of an adsorbent capable to remove heavy metals present in contaminated waters. The silica contained in the biomass was obtained by alkaline

3. Oxidized or acetylated low density lipoproteins are rapidly cleared by the liver in mice with disruption of the scavenger receptor class A type I/II gene.
Oxidized low density lipoprotein (LDL) and acetyl LDL are recognized by the scavenger receptor class A type I/II (SR-AI/II) on macrophages and liver endothelial cells. Several investigators have suggested that there are additional receptors specific for oxidized LDL, but characterization of these alternate receptors for oxidized LDL and evaluation of their q

4. Synthetic LXR ligand inhibits the development of atherosclerosis in mice
The nuclear receptors LXRα and LXRβ have been implicated in the control of cholesterol and fatty acid metabolism in multiple cell types. Activation of these receptors stimulates cholesterol efflux in macrophages, promotes bile acid synthesis in liver, and inhibits intestinal cholesterol absorption, actions that would collectively be expected to reduce athe

5. Biotoxicity of mercury as influenced by mercury(II) speciation.
Integration of physicochemical procedures for studying mercury(II) speciation with microbiological procedures for studying the effects of mercury on bacterial growth allows evaluation of ionic factors (e.g., pH and ligand species and concentration) which affect biotoxicity. A Pseudomonas fluorescens strain capable of methylating inorganic Hg(II) was isolated
