Escolha manual, seleção eletrônica pela cor, tratamento fungicida e qualidade de sementes de amendoim

Abstract: This paper had the objective to collect information concerning the effects of hand picking, electric color sorting and fungicide treatment on the quality of peanut seeds. The peanut seed were processed in a sheller with vibratory circular screen, following the seeds was classified on the 22/64" screen. Then the seeds passed through a gravity table, were the heaviest ones were separated to be used in the differents treatments. The treatments were the following: 1. the original material (check), 2. material submitted to one electric sorting, 3. material submitted to two electric sorting, 4. hand picking by 8 persons, 5. hand picking by 4 persons followed by an electric sorting, 6. material rejected by electric sorting. All the treatments were derived in two parcels and one of each was treated with the fungicide thiran (2 g.a.i. per kg of seeds). The results have indicated that the seeds rejected by the electric sorting (seeds with color was lighter or darker than the characteristic color of the cultivar, and seeds with damage tegument with exposed embryo) had the lowest physical (purity analysis and presence of seeds with damage tegument) physiological (germination test, acelered aging and emergence of seedling in the sand and in the field) and health (seed health) qualities. However the hand picking or the electric sorting methods improved only the physical quality. The treatment using fungicide improve the physiological and health qualities of the seeds.

Rat serum proteins and nutritional quality of full-fat soy flour: application of response surface methodology.

Abstract: A study was conducted to diagnose nutritional status by determining total serum proteins and electrophoretic patterns of protein reserves. Serum proteins are affected by privation of several amino acids. The purpose of the present research work was to evaluate protein quality of full-fat soy flour (FFSF) obtained from various hydrothermal processes by measuring changes in the serum proteins of Wistar rats. Response surface methodology was used as tool to determine the optimum conditions of hydrothermal process. The mean values of total serum proteins for the experimental group fed treated FFSF, were beta 0 = 5.12 +/- 0.13 g%; for the untreated FFSF group, C1 = 4.60 +/- 0.28 g%, and for the control group fed casein, C2 = 5.63 +/- 0.33 g%. All these values differ at 5% of significance (p less than or equal to 0.05). Results confirmed that treated full-fat soy flour is nutritionally superior to untreated FFSF, but not to casein.

[Arachnoid cyst of the 3d ventricle: report of 2 cases].

Abstract: In 1985 and 1986 the Department of Neurosurgery of the University of Berlin treated two cases of arachnoid cysts of third ventricle, both of which were successfully dealt with surgically. They are reported in this paper. Arachnoid cysts from ventricular system and cisterns are rare. Up to now 46 cases have been reported in the specialized literature. The computerized tomography and magnetic resonance make diagnosis easier, as shown through the cases reported.

Autonomia profissional do enfermeiro: uma conquista obtida através de um programa de extensão à comunidade

Abstract: Os autores do presente trabalho, com o objetivo de enriquecer a formacao dos alunos do Curso de Graduacao em Enfermagem, propiciando experiencias a saude e ao trabalho em equipe multidisciplinar e, ainda, estender o campo de estagio aos alunos, na disciplina Fundamentos de Enfermagem, criaram um Programa de Extensao a Comunidade. A cada avaliacao do Programa, ve os seus objetivos atingidos, tendo como destaque, a consolidacao da autonomia profissional, tanto assistencial como administrativa.

Nutrição mineral de hortaliças LXXV. doses de cálcio afetando o crescimento e concentração de macro e micronutrientes de salsao (Apium graveolens L. var. dulce) nos cultivares golden detroit e cornell 6-19

Abstract: O salsao (Apium graveolens L. var. Dulce) e uma hortalica pouco cultivada no Brasil, encontra-se atualmente em franca expansao devido o aumento da demanda pelas industrias de sopas desidratadas. Como nos paises que tradicionalmente cultivam o salsao apresentam serios problemas nutricionais, foi proposto neste trabalho os seguintes objetivos. Aquilatar o efeito de doses crescentes de calcio no seu desenvolvimento; Descrever os sintomas de deficiencia e excesso de calcio; Verificar diferencas de resistencias a anomalia do blackheart entre os cultiva res Cornell 6-19 e Golden Detroit. Para atender estes objetivos foi realizado um ensaio em condicoes controladas, cultivando-se o salsao em solucao nutritiva em presenca dos niveis de calcio - 0, 50, 100, 150, 200 e 300 ppm de Ca. Os autores concluiram que: E possivel caracterizar com nitidez a deficiencia de calcio em ambas as cultivares; A cultivar Golden Detroit apresenta maior resistencia ao aparecimento dos sintomas de deficiencia de calcio do que a cultivar Cornell 6-19. Os sintomas de deficiencia de calcio nas folhas novas de ambas as cultivares manifestam-se com a concentracao de calcio em solucao nutritiva igual ou inferior a 150 ppm; O aumento da concentracao de calcio na solucao nutritiva favorece o crescimento das plantas e ha maior acumulo de materia-seca nas doses mais elevadas. O aumento de concentracao de calcio na solucao nutritiva induz a uma diminuicao de manganes em parte aerea das plantas.
