1. Results from portable and of low cost equipment developed for detection of milk adulterations
Abstract This work presents the results of a device, MilkTech, developed to detect milk tampering, based on electrical measurements. The device indicates possible frauds by water, sodium chloride, caustic soda, ethyl alcohol and sodium bicarbonate. The advantages in relation to traditional methods are portability, low cost and detection of mixed frauds. The

2. Utilization of banana stalk fiber as reinforcement in low density polyethylene composite
ABSTRACT Natural fibers could serve as viable and abundant alternatives to the expensive and non - renewable synthetic fibers as reinforcement in thermoplastic composites. The potentiality of banana stalk fiber at reinforcing a low density polyethylene matrix was examined in this study. Fibers were extracted from the stalk of banana plant and characterized f

3. Efeito da dispersão na deslamagem e flotação de polpas de minérios hematíticos itabiríticos
Some iron ore types from Alegria and Fabrica Nova mines, mainly in the most superficial portions of their deposits, present higher hydration levels than those located in depth, being potentially generators of slimes and high alumina and phosphorus grades in the processed products. The main objective of this work was to investigate the effects of addition of

4. Antibacterial efficacy of commercial disinfectants on dirt floor used in poultry breeder houses
Dirt floors are used on most Brazilian poultry farms since the construction of concrete floors is very expensive. In vitro tests carried out to verify the effectiveness of disinfectants do not consider the adverse conditions found in poultry farms. Therefore, the present study aimed at evaluating the effect of six commercial disinfectants on the reduction of

5. EFFECTS OF A CAUSTIC LIQUEUR ON THE SHEAR STRENGTH OF A SIENITIC RESIDUAL SOIL AND A COLLUVIUM, UNDEFORMED / EFEITOS DE UM LICOR CÁUSTICO NA RESISTÊNCIA AO CISALHAMENTO DE UM SOLO RESIDUAL DE SIENITO E UM COLUVIONAR INDEFORMADOS
Neste trabalho se estuda a influência de um fluido alcalino na resistência ao cisalhamento de dois solos provenientes de Poços de Caldas-MG, sendo um deles um solo residual jovem de sienito e o outro um colúvio. Para tanto, elaborou-se um programa experimental que consistiu na execução de ensaios triaxiais CIU (solo residual jovem) e de cisalhamento di

6. Mathematical modeling of an industrial process for chlorine and caustic manufacturing using brine electrolysis aiming at its optimization. / Modelagem matemática de um processo industrial de produção de cloro e soda por eletrólise de salmoura visando sua otimização.
The present work consists on the development of a mathematical model on an industrial chlorine and sodium hydroxide production plant, aiming at the optimization of production efficiency and costs saving concerning electrical energy and vapor consumption. Two process steps were considered in the study: electrolysis and NaOH-liquor concentration by evaporation

7. Determinação simultanea, em linha, da concentração de soda caustica e de alumina em solução de aluminato de sodio do processo bayer de produção de oxido de aluminio
The objective of this project is the development of an automatic in line system to measure the alumina and caustic content in the sodium aluminate solution of the Bayer Process by using sensors and chemometrics calculations. The aluminum process production begins with the Bayer Process to extract the aluminum oxide from the bauxite, the aluminum ore. Then, t

8. LABORATORY EVALUATION OF COLLAPSE AND SOLUTE TRANSPORT CHARACTERISTICS OF A LATERITIC SOIL UNDER INFILTRATION OF A CAUSTIC LIQUEUR / ESTUDO EM LABORATÓRIO DE CARACTERÍSTICAS DE COLAPSO E TRANSPORTE DE SOLUTOS ASSOCIADAS À INFILTRAÇÃO DE LICOR CÁUSTICO EM UM SOLO LATERÍTICO
Neste trabalho se analisam as características de colapso de um solo laterítico submetido à percolação de um licor cáustico a diferentes concentrações. O solo é uma areia quartzosa com uma pequena fração de finos cauliníticos. O licor é um efluente industrial, resultante da produção de alumínio, a base de soda cáustica. Mediante o presente es

9. Ingestion of caustic substances and its complications
CONTEXTO: As substâncias cáusticas promovem a destruição dos tecidos através de reação de liquefação ou coagulação, e a intensidade de destruição depende do tipo da concentração, do tempo de contato e da quantidade ingerida. OBJETIVOS: Analisar as complicações observadas e correlacioná-las com a quantidade de "soda cáustica" ingerida. TIPO

10. STUDY OF THE EFFECT OF INFILTRATION OF CAUSTIC SODA ON THE STRENGTH CHARACTERISTICS OF A LATERITIC SOIL / ESTUDO DA INFLUÊNCIA DA INFILTRAÇÃO DE SODA CÁUSTICA NAS CARACTERÍSTICAS DE RESISTÊNCIA DE UM SOLO LATERÍTICO
This work presents the results of a laboratory study on the effects of infiltration of a caustic liqueur on the stress- strain- strength behavior of a sandy lateritic soil. The experimental program consisted of general characterization,chemicals tests, X-ray diffraction analysis, electron microscopy and triaxial tests using the caustic liqueur at different c
