Controle em pós-colheita das podridões da manga 'bourbon', conservada em câmara fria

Mangas 'Bourbon' foram conservadas em câmara fria, a temperatura de 10º C, tendo recebido previamente os seguintes tratamentos em pós-colheita: 1) controle; 2) imersão por 10' em água a 55 C; 3) imersão por 5' a 50 C em solução de Benomyl a 0,025% de p.a.; 4) imersão por 5' a 50ºC em solução de Benomyl a 0,050%; 5) imersão por 5' a 55ºC em solução de Benomyl a 0,025% de p.a. e 6) imersão por 5' a 55ºC em solução de Benomyl a 0,050% de p.a. Os resultados indicaram que todos os tratamentos, com exceção do controle, foram eficientes no controle da antracnose. Quanto à ocorrência das podridões moles, constatou-se perdas de 44, 36, 20, 20, 4 e 8% do primeiro para o sexto tratamento, respectivamente. Assim ficou evidenciado que os tratamentos à mais alta temperatura, conjugados ao fungicida Benomyl, foram aqueles mais interessantes no tratamento em pós-colheita de manga 'Bourbon' .

Implantação do mixoma infeccioso do coelho na câmara anterior do ôlho da cobaia

Mammalian cancer as well as the Rous chicken sarcoma has been successfully transplanted into the anterior chamber of the eyes of guinea pigs. It was of interest, therefore, to see if the infectious myxomatosis of rabbits, another representative of the infectious tumors, could be grown in the anterior chamber of the guinea pig eye, and, if growth occurred, to compare the tumor's behaviour with that of growths of the above mentioned etiology. Forty-three full-grown guinea pigs from mixed stocks were used throughout, and seventy-eight heterologous transplantation experiments were performed. The grafts measuring less than 2 mm. in diameter were cut from the subcutaneous tissue in skin lesions of rabbits with infectious myxomatosis recently killed. The transfer to the anterior chamber was performed after the usual technique. Some degree of partial survival was found in 23,8% of the grafts, in which typical myxoma cells could be demonstrated fifteen days after the transplantation. The transplant apparently does not increase in size, differing in that respect from that of the Rous chicken sarcoma, which increases in size by 2 or 3 diameters in 2 weeks (Shrigley, Greene & Duran-Reynals, 1945). The virus was still alive in 26% of the grafts 21 days after transplantation, and was able to induce a typical disease when injected to normal rabbits. No alteration in the properties of the virus after growth in the guinea pig was noticed, and this also is different from what happens with the Rous chicken sarcoma.

Transplantação de baço de coelho com mixoma infeccioso na câmara anterior do ôlho da cobaia: sôbre a degeneração mixomatosa: inclusões intranucleares

Heterotranplantability of myxoma of rabbits was formely demonstrated when grafts from subcutaneous tissue in skin were used (MARGARINOS TÔRRES & RITA CARDOSOS, 1949). Better results are reported in this paper when grafts from the spleen of infected rabbits were employed. While grafts from normal spleen are almost completely absorbed in sixteen days, those from infected rabbits give origin to full-grown and vascularised tissue in which typical myxoma cells are predominant elements. Progressive growth of heterotransplantated myxoma cells is another similarity between infectious myxoma and malignant tumors. Formation of clear areas of circular contour (interference of a diffusible substance?) associated to myxomatous degeneration is very conspicuous. Peculiar changes of the ground substance, reticular and collagenous fibers (globular swelling, rosary and bulb formation) apparently related to myxomatous degeneration are described. An unexpected finding was the presence of typical intranuclear inclusion bodies in five among forty-eight grafts examined in the sixth day.

Sôbre uma nova espécie do gênero Lecithochirium Luehe, 1901: (Trematoda, Hemiuroidea)

In this paper a new species of the genus Lecithochirium Luehe, 1901, is described. To simplify the study of this genus, we divided it in 3 groups according principally to the relation among the suckers. L. manteri sp. n., comes nearest to L. texanum, L. priacanthi, and L. microstomum, but differes mainly from them by the great size of the suckers, pharynx and eggs.

Els senadors carlins de Catalunya (1901-1923)

Nova aportació de l’autor sobre la presència catalana en el Senat, centrada en aquesta ocasió en els senadors carlins de Catalunya que obtingueren representació en la Cambra Alta durant el període 1901-1923. Aquesta publicació complementa, doncs, Els senadors republicans catalans durant la monarquia d’Alfons XIII (WP 249/06) i Els senadors conservadors (WP 260/07).

Modelado de una cámara de onda milimétrica

En aquest projecte s'ha dissenyat i simulat una càmera d'ones mil·limètriques mitjançant "Spinning Reflectors" amb l'objectiu d'estudiar la qualitat de les imatges obtingudes, així com determinar la configuració de reflectors acceptable per a la nostra càmera. Per al seu disseny, s'ha realitzat el model d'una antena Cassegrain amb botzina alimentadora a FEKO i s'han simulat els diagrames de radiació corresponents als diferents angles de rotació d'ambdós reflectors al voltant de l'eix en el qual estan situats. Finalment, a partir del principi de funcionament de la nostra càmera, s'ha exposat la seva implementació física i s'ha representat en Matlab la seva PSF (Point Spread Function) i la imatge d'un objecte arbitrari d'acord amb les tècniques de formació d'imatges.

The impact of women's educational and economic resources on fertility: Spanish birth cohorts 1901-1950

In this chapter we portray the effects of female education and professional achievement on fertility decline in Spain over the period 1920-1980 (birth cohorts of 1901-1950).A longitudinal econometric approach is used to test the hypothesis that the effects of women’s education in the revaluing of their time had a very significant influence on fertility decline. Although in the historical context presented here improvements in schooling were on a modest scale, they were continuous (with the interruption of the Civil War) and had a significant impact in shaping a model of low fertility in Spain. We also stress the relevance of this result in a context such as the Spanish for which liberal values were absent, fertility control practices were forbidden, and labour force participation of women was politically and socially constrained.
