1. Crystallurical profile in sheep after ammonium chloride supplementation
RESUMO Apesar de cristais urinários serem componentes habituais, a formação de urolitíase é sempre precedida dessas concreções. O presente estudo objetivou identificar a mudança do perfil cristalúrico em ovinos suplementados com cloreto de amônio. Foram utilizados 25 ovinos, machos, com idade de três meses, confinados e distribuídos aleatoriament

2. Organophilic clays and their application in atrazine adsorption
Abstract Atrazine’s adsorptive capabilities make the use of clays practical and effective. Three types of organophilic clays modified by cationic surfactants with the ability of one of these clays to adsorb atrazine in an aqueous medium are discussed in this work. The modification in clays was done with the surfactants cetyltrimethylammonium bromide, cetyl

3. Structure-Physical Properties Relationship of Eutectic Solvents Prepared from Benzyltriethylammonium Chloride and Carboxylic Acids
Deep eutectic solvents (DESs) have attracted the attention of the researchers as alternative solvents due to desirable properties such as easy preparation and high thermal stability. In this work, it was reported the preparation of five DESs from benzyltriethylammonium chloride (BTEAC) as quaternary ammonium salt (QAS) and carboxylic acids (oxalic, malonic o

6. Potassium chloride: impacts on soil microbial activity and nitrogen mineralization
RESUMO: O cloreto de potássio (KCl) é a fonte de potássio mais utilizada mundialmente e, devido ao uso contínuo desse fertilizante, pode ocorrer acúmulo de sais no solo e nas plantas. O excesso de íons desencadeia uma série de distúrbios fisiológicos, tornando-se um potencial biocida no solo. Objetivou-se avaliar o efeito da aplicação de doses de

7. The Role that Electrolytes Play in the Synthesis of Water-Soluble CdTe Quantum Dots Prepared at Ambient Temperature
In this work, we have synthesized CdTe quantum dots (QDs) dispersed in an aqueous medium at ambient temperature, and investigated their optical properties. Synthesis of CdTe QDs in the presence of simple amines removed the need for an additional energy source and inert atmosphere, in a simple and inexpensive experimental setup. The use of ammonia or hydrazin

8. Synthesis of Submicrometer Calcium Carbonate Particles from Inorganic Salts Using Linear Polymers as Crystallization Modifiers
In this study, we report the synthesis of submicrometer calcium carbonate particles using the simplest approach of mixing solutions of calcium chloride and ammonium carbonate inorganic precursors in the presence of crystallization modifiers. Instead of the typical crystallization of CaCO3 into large calcite crystals with rhombohedral morphology, very small u

9. EXPERIMENTAL STUDY ON THE COLLABORATIVE DRAG REDUCTION PERFORMANCE OF A SURFACTANT SOLUTION IN GROOVED CHANNELS
Abstract Turbulence with a relatively larger vortex is obtained in drag-reducing surfactant solution, which provides an excellent condition for the application of small scale grooves. In this work, the coupling drag reduction performance of surfactant solution and grooves was experimentally investigated to explore the complementary possibility between their

10. Synthesis and Microstructural Characterization of SnO2:F Thin Films Deposited by AACVD
In this work, we report the synthesis and microstructural characterization of Tin oxide thin films doped with fluorine for applications such as transparent conductive oxides. Tin oxide doped with fluorine thin films were deposited by aerosol assisted chemical vapor deposition technique onto a borosilicate glass substrate, using a precursor solution of stanni

11. A Simple Way to Produce γ-Alumina From Aluminum Cans by Precipitation Reactions
Abstract In this paper, a new way for γ-alumina synthesis was proposed, the raw material being aluminum powders obtained by high-energy milling of aluminum cans. This seems a good option for this metal recycling and energy saving, as well as hydrogen production. The materials were prepared by precipitation techniques, in which aluminum powders reacted with

12. Evaluation of Disinfectants Used in Pre-Chilling water Tanks of Poultry Processing Plants
ABSTRACT In poultry processing plants, disinfectants are often added to pre-chilling water tanks to reduce microbial contamination. The present study aimed at evaluating the effect of five disinfectants (acidified sodium chlorite, alkyl dimethyl benzyl ammonium chloride, chlorine dioxide, peracetic acid, and sodium hypochlorite) on the populations of food qu
