Modulation of the effectiveness of 17-alpha-hydroxy-20-beta-dihydroprogesterone or of a gonadotrophic extract on the in vitro intrafollicular maturation of oocytes of the rainbow trout Salmo gairdnerii by various non-maturing steroids [Translation from: Compte Rendu Hebdomadaire des Seances de l'Academie des Sciences, Paris, Series D 281, 811-814, 1975]

The effectiveness of 17 α-hydroxy-20 β-dihydroprogesterone (17 α-20 β Pg) or of a trout hypophyseal gonadotrophic extract on the in vitro intrafollicular maturation of trout oocytes can be modulated by steroids which do not have a direct maturing effect; the effectiveness of the gonadotrophic extract is lowered by oestradiol and oestrone and increased by testosterone. As these steroids have no significant effect on maturation induced by 17 α-20 β Pg, the site of their activity is probably in the follicular envelopes. Corticosteroids, and Cortisol and cortisone in particular increase the effectiveness of the gonadotrophic extract, but increase the effectiveness of 17 α-20 β Pg even more strongly, suggesting that this 'progestagen' has a direct effect on oocyte sensitivity.

Lei 5.811/72: uma análise das suas injustiças e ineficiências e dos ajustes possíveis

O presente trabalho analisa as ineficiências e injustiças da Lei 5.811/72, lei esta que veio para regulamentar a atividade dos trabalhadores na indústria do petróleo de forma geral, incluindo plataformas marítimas de exploração de petróleo, diferenciando os regimes de revezamento e sobreaviso e apresentando todos os benefícios inerentes a estes. Com o propósito de debater os custos do trabalho sob a égide da Lei 5811/72, esse trabalho traz uma análise comparativa entre os trabalhadores que são regulados por está lei e aqueles regulados pela CLT, propondo, ao final, implementar um projeto de lei com possíveis ajustes em alguns desses custos, vistos como injustos e a criação de uma nova norma regulamentadora para trazer meios eficazes e efetivos de fiscalização ao sistema. No interesse de coibir iniqüidades na aplicação da lei, esse trabalho sugere o acréscimo de direitos inerentes aos trabalhadores e mesmo aos empregadores, para chegar a um sistema mais justo para todos.

EC27-811 Harvesting Wheat in Nebraska with the Combined Harvester Thresher 1926

Frequent inquiry from wheat growers in Nebraska and others as to the relative merits of the combined harvester-thresher as an efficienct and economical harvesting machine led the Nebraska Agricultural College to make a study of this problem in the summer of 1926. The work was carried on by the Departments of Rural Economics and Agricultural Engineering, cooperating with the United States Department of Agriculture which was conducting a similar survey in different parts of the United States. Perkins county, Nebraska, was the area selected for study as it is more or less typical of those parts of the state where combines are used extensively. The purpose of this circular is merely to give such informaition as is available regarding harvesting costs by different methods in Nebraska and not to recommend one method over another since location, acreage, climatic conditions, and topopgraphy all have their influence in determining the most economic method for different communities.
