1. Effects of Forming Processes on Microstructures and Mechanical Properties of A356 Aluminum Alloy Prepared by Self-inoculation Method
Semisolid slurry of A356 aluminum alloy was prepared by Self-Inoculation Method (SIM), and the microstructures and solidification behavior of rheo-forming process in different forming processes were researched. The results indicate that semisolid slurry of A356 aluminum alloy can be prepared by Self-Inoculation Method at 600ºC. Primary α-Al particles with

2. Symbiotic effectiveness of Bradyrhizobium ingae in promoting growth of Inga edulis Mart. seedlings
ABSTRACT Inga edulis Mart. is a leguminous tree adapted to acidic and low-fertility soils that establishes symbioses with nitrogen (N)-fixing bacteria. The identification of effective bacteria in biological N fixation may bolster the use of I. edulis in degraded or modified areas and agroforestry systems. Therefore, the aims of this study were evaluation of

3. Cowpea symbiotic efficiency, pH and aluminum tolerance in nitrogen-fixing bacteria
Cowpea (Vigna unguiculata) cultivation in northern and northeastern Brazil provides an excellent source of nutrients and carbohydrates for the poor and underprivileged. Production surplus leads to its consumption in other regions of Brazil and also as an export commodity. Its capacity to establish relationships with atmospheric nitrogen-fixing bacteria is cr

5. Análise térmica de ligas Al-Si com adição de inoculante. / Thermal analysis of the Al-Si alloys with addition of inoculant.
As ligas Al-Si hipoeutéticas têm grande importância na indústria de fundição de peças devido às excelentes propriedades de fundição, como baixo ponto de fusão e alta fluidez. A análise térmica das curvas de resfriamento medidas durante a solidificação destas ligas pode ser utilizada para controlar a formação da macroestrutura de grãos. Esta

6. FixaÃÃo biolÃgica de nitrogÃnio e solubilizaÃÃo de fosfatos por bactÃrias isoladas de nÃdulos de caupi [Vigna unguiculata (L.) Walp.] / Biological nitrogen fixation and phosphate solubilization by bacteria isolated from cowpea nodules [Vigna unguiculata (L.) Walp.]
The biological nitrogen fixation and solubilization of insoluble inorganic phosphates are processes mediated by soil microorganisms which can increase crop productivity. The objective of this study was to isolate and select bacteria nodulating cowpea and efficient in biological nitrogen fixation and solubilization of insoluble phosphates and, to identify and

7. The effects of low-level laser on muscle damage caused by Bothrops neuwiedi venom
The present study aimed to assess the effects of low-level laser (660 nm) on myonecrosis caused by the insertion of Bothrops neuwiedi venom in the gastrocnemius muscle of rats. Male Wistar rats were divided into three groups (n = 24 each): Group S (0.9% saline solution); Group V (venom) and Group VLLL (venom plus low-level laser). These categories were subdi

8. Efeito de Alumínio, Molibdênio e de Estirpes de Rizóbio em Arachis pintoi / Effect of Aluminum, Molybdenum and strains of Rizóbio in Arachis pintoi
In a modern cattle-breeding using pastures that allows a gain of weight is an essential factor. The Arachis pintoi is an option to a good alimentary diet and to the recuperation of degraded pastures, due to its potential in biological fixation of nitrogen and resistance to acid soil with high contents of aluminium. Experiments were conducted in greenhouse an

9. Yield and quality of peanut cultivars seeds affected by liming and haversting time. / Produção e qualidade de sementes de cultivares de amendoim (Arachis hypogaea L.) influenciadas pela calagem e pela época de colheita
The objective of liming is the neutralization of soil aluminum and manganese, as well as the supply of calcium, the increase of nutrient availability at the frut forming zone of in the soil and the increase of seed tegument thickness which may serve as a barrier to fungi penetration and water loss. In Experiment I, six peanuts cultivars yield components and

10. Crescimento do cafeeiro sob influencia do aluminio em solução nutritiva e em solo acido, inoculado com micorrizas arbusculares
Under greenhouse conditions, it was set up two experiments during the years 2000 and 2001, in order to study the toxicity of aluminum to coffee plants. In the first experiment the objective was to evaluate the differential response of eleven coffee cultivars to AI levels (O, 0.148, 0.296, and 0.592 mmol/L) in nutrient solutions study. In the second experimen

12. Bronchopulmonary Cellular Response to Aluminum and Zirconium Salts
The bronchopulmonary cellular immunological response to repeated intratracheal inoculation of aluminum chlorhydrate, sodium zirconium lactate, and zirconium aluminum glycine was examined in rabbits. Results of a dose-response experiment using 0.1, 1.0, and 10.0-mg intratracheal inoculations of each metallic salt demonstrated significant bronchopulmonary hist
