1. STATIC PRESSURE DROP IN LAYERS OF CASTOR BEAN GRAINS
ABSTRACT Knowledge regarding the static pressure drop in granular layers is of fundamental importance in the development of efficient drying and aeration projects of agricultural products. Thus, the objective of this study was to evaluate the effects of impurity contents on the static pressure drop in different bed depth of castor bean grains, as well as mod

2. Desempenho de diferentes estrategias de aeração de milho armazenado / Performance of different aeration strategies for stored corn
The efficiency of grain storage doesn t consist only to "save" the agricultural production, but mainly to avoid the problem with the moisture migration, incidence of insects and development of microorganism in grains, during the process. Aeration is currently used for reducing and homogenization the intergranular temperature, aiming to minimize these problem

3. Simulation and real time control for grains aeration systems / Simulação e controle em tempo real para sistemas de aeração de grãos
In this work, an aeration system for stored grains aeration control was developed based on real time data acquisition and on the process simulation. Thus, a software was written by using the Java programming platform, being able to manage the data transmission and to execute actions related to the aeration control strategy. This software, called AERO, is als

4. Desenvolvimento de módulo computacional para a secagem estacionária de sementes / Development of a computational module for stationary seed dryng
The present work had for objective the development of a microcomputer program to determine the drying time of seeds and crops for fixed bed. It was used three lots of soybean seeds of cultivate Monsoy 7575 storage in a perforated floor drying bin with 1,86m of diameter and seed depth of 1,21m. The seeds were dried to 12% (wet basis). Before storage, the seed

5. Efeitos da compactaÃÃo do solo e da umidade sobre a absorÃÃo de N, P, K, os componentes de produÃÃo e a produtividade de grÃos de arroz. / Effects of soil compaction and moisture upon the uptake of N, P,K , yield components and rice grain yield
The work was intended to study the effects of different compaction levels and water management upon the uptake of nitrogen (N), phosphorus (P) and potassium (K), the development of the root system and shoot of rice plants , the yield components and rice grain yields grown in two sorts of soil. The experiment was conducted in greenhouse of the Agriculture Dep

6. Tecnologia 1-wireTM aplicada ao controle em tempo real de sistemas de aeração de grãos / The 1-wireTM technology applied to real time control of grain aeration systems
In this work, a real time intelligent control system for stored grain aeration systems was developed, employing the 1- wireTM technology developed by Dallas Semiconductor. The standard thermocouples, commonly used in aeration systems, were replaced by DS1820 digital temperature sensors. This technology allows for a half duplex data transfer and each device c

7. Production of Fumaric Acid in 20-Liter Fermentors
The conditions necessary for the production of fumaric acid in 20-liter fermentors by fermentation of glucose with Rhizopus arrhizus strain NRRL 2582 were determined. Continuous neutralization of fumaric acid was necessary for optimal yields. Yields of the calcium salt were in excess of 65 g of fumaric acid from 100 g of sugar consumed during fermentation of
