1. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

2. MONITORAMENTO DA COMPOSIÇÃO EM ÉSTERES DO BIODIESEL DO ÓLEO DE AMÊNDOA DA MACAÚBA (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) EM CONTATO DIRETO COM O AÇO CARBONO E O AÇO CARBONO GALVANIZADO
The oil from the macaúba (Acrocomia aculeata) fruit, a native palm in Brazil, has a real potential for the industrial production of biodiesel. This report describes an experimental work devoted to monitor the chemical behavior of the fatty acid methyl esters from oil of the macaúba fruit kernel and the leaching of metal elements into the biodiesel put in c

3. Influence seasons of the year and somatic cell counts on physical-chemical and sensory parameters of milk and coalho cheese
ABSTRACT. The objective of this study was to evaluate the influence seasons of the year and somatic cell counts (SCC) on physical-chemical and sensory parameters of cow’s milk from individual and collective refrigeration tanks with different milking systems. In addition to analyzing the sensory acceptance of pasteurized milk and coalho cheese developed w

4. Analytical study of cylindrical tanks including soil-structure interaction
Resumo Um estudo analítico voltado para o projeto de tanques cilíndricos para armazenagem de líquidos, apoiados sobre fundação deformável, é desenvolvido neste trabalho. O solo sob os tanques é modelado como um meio elástico linear. A parede cilídrica é considerada rigidamente conectada à placa de fundação. Aqui, tanques de concreto são enfati

5. Source-sink relationships in two soybean cultivars with indeterminate growth under water deficit
Abstract Water deficit is a major factor limiting crop yield in rainfed areas. We hypothesized that under water deficit the decrease of photosynthetic production stimulates: carbohydrate remobilization from leaves, stems and roots to reproductive organs; and decreasing flowering intensity and pod development. The present work aims to study the effect of wate

6. MATHEMATICAL MODELLING AND SOLUTION APPROACHES FOR PRODUCTION PLANNING IN A CHEMICAL INDUSTRY
ABSTRACT This paper addresses a lot sizing problem in a Brazilian chemical industry where a product can be produced by more than one process, which can use different parallel machines and may even consume a wide range of raw materials. Moreover, most of the products are liquids and the inventories must be kept in a restricted number of storage tanks with a l

7. THE BRAZILIAN EXPERIENCE WITH ETHANOL FUEL: ASPECTS OF PRODUCTION, USE, QUALITY AND DISTRIBUTION LOGISTICS
Abstract The reduction in the availability of fossil fuel increased the search for alternative fuel sources (for example, ethanol). In the Brazilian market, light duty vehicles can be fueled with gasohol (18 up to 27.5 %v/v of anhydrous ethanol in gasoline) and/or hydrous ethanol. To minimize the risk of water-induced phase separation of gasoline-ethanol ble

8. Simplified Analytical Approach to Evaluate the Nonlinear Dynamics of Elastic Cylindrical Shells Under Lateral Blast Loads
Abstract This paper presents an analytical solution to predict the nonlinear forced vibrations of elastic thin-walled cylindrical shells under suddenly applied loads. Interest in this problem is motivated by effects due to explosions on fluid-storage metal tanks. The model is based on the energy criterion due to Lagrange, in which the kinematic nonlinear rel

9. Production of Additives with Antimicrobial Activity via Tandem Hydroformylation-amine Condensation of Soybean FAME Using an Ionic Liquid-Based Biphasic Catalytic System
A biphasic catalytic system based in the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate was employed for tandem hydroformylation-amine condensation reactions of soybean FAME using HRhCO(PPh3)3 as the catalyst precursor and n-butylamine. Using a tenfold excess of the ligand PPh3, the presence of the ionic liquid increased the selectivity for imi

10. REMOVAL OF WATER CONTENT FROM BIODIESEL AND DIESEL FUEL USING HYDROGEL ADSORBENTS
Abstract The removal of water content present in fuels such as biodiesel and diesel is quite important to adequate the fuel to standards for commercialization and to avoid corrosion of storage tanks and injection equipment in diesel engines. In this study, hydrophilic hydrogels were employed to remove the water content in biodiesel and diesel fuel samples. T

11. Decontamination of naturally contaminated liquid nitrogen storage tanks
The objective of this study was to evaluate the efficacy of cleaning and decontamination procedures in liquid nitrogen tanks. We evaluated 151 canisters and 133 bottoms from 133 nitrogen tanks of companies or farms for the presence of bacteria and fungi. Samples were collected from the canisters and the bottom of tanks containing liquid nitrogen. Tanks were

12. Stress concentration around perforations produced by corrosion in steel storage tanks
This paper presents numerical results of stress concentration factors for plates perforated by corrosion. Evidence from 25 plates with corrosion perforation considered show that typical shapes may be characterized as a deviation from an ellipse or from a circle. In order to model typical perforations created by this type of corrosion, holes with non-circular
