Passageiros de terceira classe: o transporte de emigrantes na história econômica da Navigazione Generale Italiana

From the 1860s, the Italian emigration reached many entily, becoming on national problem and a source of revenue for shipping companies operating in the Atlantic. In Italy, the resources were fundamental in financing the replacement of the old sailboats by more modern steamers. Established in 1881, the Navigazione Generale Italiana (NGI) had not scoped to carry passengers. It acted in trade of goods conjugated with postal services widely subsidized by the state. By incorporating that transported immigrants, in a concentration process that would transform it in the largest shipping company in Italy, the NGI opened the thriving business of emigration to the Americas. Based on reports and Balance Exercises Financial of the company between the years 1881 and 1915, papers relating to merchant shipping and emigration legislation (laws of 1888 and 1901), this paper aims to present some results of research on the importance trafficking of Italian emigrants Navigazione Generale Italiana for marking the specialization process of its fleet this kind of service.

Imprensa italiana em São Paulo e o fascismo: o Fanfulla (1921-1942)

This article intends to verify the Fanfulla's action in the dynamic of the political propaganda, as well as the cultural exchanges established with the fascism during 1922-1924. The leading question is insert on the political culture studies concerned with the significance of the fascism spread among the Italian immigrants and his descendants located on the Sao Paulo State. It unfold in others questions: the reason of the Mussolini government pledge to publish those ideas, the themes approached in this propaganda, the reactions it rise, as well on the Italian community, the Brazilian government and political movements. On this issue is included the position of the Brazilian government, on the Brazilian diplomacy or in the repressive agencies toward fascist Italy and the supporters of the fascism. The choice of the newspaper Fanfulla is justified for its position in the historiography, considered the most expressive source for this study, due its longevity, relations with the fascist regime and diffusion on Sao Paulo State.

Poda apical para produção de frutos e sementes de abóbora

The tip pruning stimulates the emission of lateral shoots, thus can produce higher number of flowers, fruits and seeds. This work aimed to evaluate the effect of apex pruning on fruit and seed production in pumpkin. The treatments consisted of plants without pruning, with pruning in the sixth, eighth and tenth node of main stem. The experimental design was a randomized block, with six replications. It was studied a line of pumpkin of the Germplasm Bank of the Universidade Estadual Paulista/Faculdade de Ciências Agronômicas. The characteristics evaluated were: number of branches per plant and fruit position in branches of the plant production (number and weight) of fruits per plant, fruit yield, fruit average weight, fruit length and diameter, seed weight per fruit, seed yield and quality (germination test, first count, thousand seed weight, emergence, speed of emergence and accelerated aging). There was a significant difference only for number of secondary branches per plant and thousand seed weight, with larger values for plants that have not been pruned. It was obtained high average of germination (94%) and good fruit (16.9 t ha-1) and seed (148 kg ha-1) yield. The apex pruning does not influence the production of fruits and seeds, as well as the physiological seed quality in pumpkin.

Colored polyethylene soil covers and grafting effects on cucumber flowering and yield

O pepino (Cucumis sativus L.) é, dentre os produtos hortícolas, um dos mais visados para o cultivo em estufas no Brasil devido ao ciclo vegetativo curto e ao elevado valor econômico no período da entressafra. Estudou-se, em condições de ambiente protegido, a influência de diferentes cores de cobertura plástica de solo no florescimento e na produção de pepino híbrido 'Yoshinari' enxertado ou não sobre abóbora híbrida 'Ikky'. Os tratamentos de cobertura foram: preto, preto pintado de branco, verde, e sem cobertura. Os tratamentos cobertos com plástico e sem enxertia apresentaram florescimento com distribuição mais uniforme na planta. O número de flores foi superior no tratamento preto/branco enxertado. Para as plantas não enxertadas, todas as coberturas favoreceram o florescimento. A enxertia favoreceu o florescimento somente para os tratamentos com plástico preto ou verde. A fixação dos frutos aumentou pelo uso de cobertura plástica, mas a enxertia não teve influência. A distribuição uniforme do florescimento manteve-se na frutificação apenas para os tratamentos com plantas enxertadas e cobertura do solo com plástico preto ou verde. Tanto o uso de cobertura plástica quanto a enxertia favoreceram a colheita precoce. Os frutos de melhor qualidade e as maiores produções, em número de frutos, foram obtidos nos tratamentos preto e preto/branco, não enxertados. A enxertia 'Yoshinari'/'Ikky' provocou o aparecimento de frutos mais grossos e menores, fora do padrão de comercialização.

Produção de pepino de plantas enxertadas cultivadas em soluções nutritivas com diferentes teores de potássio

O experimento foi conduzido em estufa tipo arco de 50 m² na Faculdade de Ciências Agronômicas da UNESP em Botucatu. Plantas de pepino (Cucumis sativus L.) não enxertadas e enxertadas em abóbora (Cucurbita sp.) foram cultivadas em sistema hidropônico para estudar o efeito de níveis de potássio (45; 90; 180 e 360 mg.L-1 de K) na altura da planta e produção de número de frutos/m². A condução das plantas foi em vasos de 28 L de capacidade contendo 20% vermiculita + 80% casca de arroz + solução nutritiva fornecida a partir de galões individuais contendo 20 litros de solução. O delineamento experimental foi blocos casualizados, com oito tratamentos (fatorial 4 x 2) e três repetições. Não houve efeito da enxertia e das doses de K sobre a altura da planta, porém, os níveis de potássio independente da enxertia alteraram o início da floração. A enxertia potencializou a produção aumentando em 39% o número de frutos/m² quando fornecido na solução nutritiva 45 mg.L-1 de K e 144% com 360 mg.L-1 de K. O menor teor de potássio, 45 mg.L-1, foi suficiente para atingir alta produção.

A construção do olhar: a Viagem à Itália, de Goethe

Investiga-se a Viagem à Itália de Johann Wolfgang von Goethe, obra que narra a viagem à península italiana de 1786 a 1788, publicada em 1816-1817. Contudo, mais do que uma reconstrução de sua viagem através das memórias e diários, a Viagem importa, antes de mais, como uma narrativa da construção de um novo olhar para com a obra de arte, como a construção da própria estética goetheana.

Catch and selectivity parameters of the anastomid fish Schizodon nasutus using gillnets in the Jurumirim reservoir (São Paulo, Brazil)

Catch and selectivity parameters using gillnets were calculated for Schizodon nasutus in the Jurumirim reservoir on the Parana-panema River in southern Brazil. The simple gillnets used were made of monofilament nylon of 30 to 140 mm mesh size an of different heights. The relative abundance of the S. nasutus caught was analysed monthly and a positive relationship was found between catches per unit effort in number and biomass. The relative catches were more abundant for the nets of 40 and 50 mm, mesh size. Catches were characterized by clear temporal variations and a predominance of medium size fish throughout the study period. The selectivity curve of gillnets for S. nasutus in this ecosystem was obtained. The catch obtained was compared with the available catch for each mesh size, and the available catch for a certain length of fish was calculated starting from the theoretical selectivity curve. The 50 mm mesh size gillnet showed the best fit between real and available captures and was considered the most suitable, because a smaller mesh size resulted in a catch of predominantly immature specimens. It is expected that these results will contribute to improving management strategies for conservation of resources. Parameters such as the minimum catch length advisable or the mesh size permitted for a given species are indispensable for such decision-making.

The Hamilton-Jacobi approach to Teleparallelism

We intend to analyse the constraint structure of Teleparallelism employing the Hamilton-Jacobi formalism for singular systems. This study is conducted without using an ADM 3+1 decomposition and without fixing time gauge condition. It can be verified that the field equations constitute an integrable system.

Prediction of R plus R-2 gravity for the deflection of a photon passing close to the Sun

The cross-section for the scattering of a photon by the Sun's gravitational field, treated as an external field, is computed in the framework of R + R-2 gravity. Using this result, we found that for a photon just grazing the Sun's surface the deflection is 1.75 which is exactly the same as that given by Einstein's theory. An explanation for this pseudo-paradox is provided.
