2. 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

3. Physiological quality of castor bean seed genotypes stored at two temperatures
ABSTRACT. Environment and storage time influence stored seed quality, especially for oilseeds such as castor beans because they have a high lipid content and are more prone to deterioration. This study evaluated the physiological quality of seeds from three castor bean genotypes stored at 10 and 20°C for 300 days. The experimental design was completely rand

4. CASTOR BEANS QUALITY SUBJECTED TO DIFFERENT STORAGE TEMPERATURES AND PERIODS
ABSTRACT The control of the temperature of the storage air have the ability to improve a better preservation of some types of agricultural products. However, the most effective temperature for storage as well as the duration of storage varies between products. Therefore, special attention should be concentrated on the storage temperature and its effects on t

5. Analysis of castor bean ribosome-inactivating proteins and their gene expression during seed development
Ribosome-inactivating proteins (RIPs) are enzymes that inhibit protein synthesis after depurination of a specific adenine in rRNA. The RIP family members are classified as type I RIPs that contain an RNA-N-glycosidase domain and type II RIPs that contain a lectin domain (B chain) in addition to the glycosidase domain (A chain). In this work, we identified 30

6. PRESSUPOSTO DA NORMALIDADE MULTIVARIADA PARA O TESTE DE RAZÃO DE VEROSSIMILHANÇA ENTRE DOIS GRUPOS DE CARACTERES DE MAMONEIRA / ASSUMPTION OF MULTIVARIATE NORMALITY FOR THE LIKELIHOOD RATIO TEST BETWEEN TWO GROUPS OF CHARACTERS OF CASTOR BEANS
The likelihood ratio test for independence between two groups of variables allows us to identify whether there is a dependency relationship between two groups of variables, ie, if the covariance between the two groups are zero. This test assumes normality multivariate data, which limits its application, in many studies of agronomic area, times when you need

7. Rendimentos das culturas e características do solo após a aplicação de resíduos da produção de biodiesel / Plants growth and soil properties modifications after several biodiesel residues applications
Alguns resíduos gerados na indústria de biodiesel podem constituir o passivo ambiental desta atividade, sendo a utilização agrícola uma alternativa para o manejo dos mesmos. Com o objetivo de avaliar a possibilidade de utilização da borra oleosa ácida de soja e do farelo de mamona em associação com adubos minerais solúveis ou com adubo orgânico (

8. Efeito da substituição do feno de capim Tifton (Cynodon ssp) por casca de mamona (Ricinus communis) em dietas a base de palma forrageira (Nopalea cochenilifera Salm Dick) sobre o perfil de metabólitos energético-protéicos e mineral em ovinos. / Effect of replacement tifton hay Cynodon spp) for castor beans hulls Ricinus communis) based diets of spineless cactus (Nopalea cochenilifera Salm Dick) metabolites on the profile of mineral and energy-protein in sheep.
Avaliou-se perfil metabólico de ovinos recebendo dietas a base de palma forrageira (Nopalea cochenilifera Salm Dick) com diferentes níveis de casca de mamona (Ricinus communis) em substituição ao feno de tifton. Foram utilizados 28 carneiros adultos, inteiros, sem padrão racial definido, com peso vivo médio inicial de 18 kg. Amostras de sangue foram co

9. Respostas dos grãos de mamona AL Guarany 2002 ao tratamento térmico visando ruptura e remoção do tegumento / Response of AL Guarany 2002 castor beans to thermal treatment aiming disruption and removal of the seed coat
Atualmente o Brasil ocupa o terceiro lugar no ranking mundial na produção e extração do óleo de mamona (Ricinus communis L), correspondendo a 13,2%, depois da Índia e da China, primeiro e segundo maiores produtores, respectivamente. Os frutos de mamona, depois de colhidos, são secos e debulhados obtendo os grãos, os quais são armazenados para poster

10. Direct analysis of biodiesel microemulsions using an inductively coupled plasma mass spectrometry .
An analytical procedure for direct introduction of biodiesel samples into an inductively coupled plasma mass spectrometer (ICP-MS) by using microemulsion for sample preparation was developed here. Cadmium, Co, Cu, Mn, Ni, Pb, Ti, and Zn were determined in biodiesel microemulsified samples prepared from different oleaginous sources (African palm, castor beans

11. Sistemas produtivos de mamona para a produção de matéria-prima para biodiesel na região nordeste do Brasil
Brazilian Biodiesel Program aims at the insertion of family agriculture in the biodiesel production chain, especially at the Northeast region (in this case, providing castor beans as the raw material for biodiesel). However, there are some evidence that this incorporation is not being met. For example, according to the Brazilian Biodiesel Program biodiesel p

12. Water and energy fluxes in cowpea and castor beans cultivated in northeast Brazil / Fluxos de Ãgua e de energia em feijÃo macassar e mamona no nordeste do Brasil
The castor beans and cowpea are crops of enormous economic and social importance for the farmers in northeast Brazil, whereas the extracted oil of seeds of castor beans is used for production of biodiesel and the cowpea is the main food for poor population. Independent of crop type, the knowledge of water amount removed from soil by vegetation is of great in
