Do vento ao vapor em mares já antes navegados: a companhia de navegação La Veloce e o transporte de emigrantes pelo Atlântico

In the final decades of the nineteenth century, the growth of Italian emigration was constituted in a secure source of income for the shipping companies that operated in the Atlantic and played a major role in financing the replacement of old sailboats by modern steamers. Based on reports and balance exercises financial, besides newspapers related to mercantile marine, this article aims to present some results of the research about the importance of Italians emigrants’ transporting to the shipping company La Veloce, showing its economic trajectory and particularities.

Museus ferroviários do Estado de Sao Paulo (Brasil): as políticas de conservação e o estado atual do patrimônio ferroviário brasileiro

This paper is to discuss the expansion and partly dismantlement of Brazilian merchant marine, tracking their legal, administrative and planning. The analysis period extends from the formation of the Comissão da Marinha Mercante, 1941, to the end of the government of Fernando Henrique Cardoso, 2002. In this long duration it is discussed the formation of the national system of economy and the dynamics of contradictory national merchant navy. The text is divided into two parts: 1) Expansion: The centralization, the planning and nationalization with the formation of the shipbuilding industry, highlighting the actions of the Comissão da Marinha Mercante and the Superintendência Nacional da Marinha Mercante, planning and financing the national navigation; 2) Demolition part: the denationalization and privatization of the national navigation, in addition to the deep restructuring of the shipbuilding industry, highlighting the creation of the Agência Nacional de Transporte Aquaviários during the last years of Fernando Henrique Cardoso government.

Interdisciplinary project applied to engineering education: construction of a miniature ceramic industry

The greatest challenge of undergraduate engineering courses is to encourage creativity, cooperation with other students, teamwork, and motivation in the first years of their courses. While students have little or no contact with advanced disciplines, it is very difficult to attract their interests and encourage them to develop the skills in their undergraduate courses. This work aims to achieve these objectives through a mini-factory project involving the construction of a production line of ceramic tiles on a laboratory scale, from the ceramic processing using raw materials to the shipping of the final product. Having been given an established monthly demand for ceramic tiles, the students determined the construction requirements of the mini-factory, as they have created the layout, including the processing equipment, the dimensioning of equipment, and its operational structure. This article intends to describe the successful creation of the ceramic tile mini-factory, including the objectives, benefits, and inherent difficulties of the process and the receptivity of the exercise by the students involved.

Effectiveness of the compound chlorpyrifos plus cypermethrin plus citronellal against Alphitobius diaperinus. Laboratory analysis and residue determination in carcasses

Biological security and the absence of residues in meat Effectiveness, and/or eggs must be considered when recommending options for the control Alphitobius diaperinus in poultry production environments. This research study evaluated the effectiveness of cypermethrin+chlorpyrifos+citronellal in the control of A. diaperinus, including analysis for the presence of residues of this compound in poultry carcasses (experimental farm). Two studies were carried out under laboratory conditions. One used paper filters a four dilutions of the compound, and the other used a container including with pulverized broiler litter and the compound. The analysis of carcasses for residues was conducted in broilers that raised in a broiler house treated (floor and/or litter) with the compound at a dilution of 1:800. Birds were regularly sacrificed, submitted to necropsy, and liver, muscle and fat fragments were collected. Gas chromatography was used to identify the possible presence of any chemical residue in these samples. High effectiveness rates against A.diaperinus were observed in the two laboratory studies, as well as the absence of residues in the carcasses. This compound, can be recommended as a valuable used in the studied concentrations, alternative for the control and treatment of A. diaperinus.

Avaliação da migração de nifas de Scaptocoris carvalhoi Becker, 1967 (Hemiptera, Cydnidae) em plantas de importância econômica e invasora em teste com oportunidade de escolha

One of the factors that affect the control of brown - roots environmental bedbug is the wide availability of plant species. Thus, this study aimed to evaluate the migration of nymphs of the brown - roots between plant species of economic importance and invasive stinkbug. Eight species of plants have been established in a set formed by eight circular PVC containers, connected symmetrically with free communication to a central circular container. The experiment was arranged in a completely randomized design and consisted of eight treatments and six replications. The test evaluations were performed on 15o , 30o , 45o and 60o days after the release of the nymphs, by counting the insects that migrated to the roots of different plants. It was observed that by the 30o day of early release nymphs, no significant differences (P < 0,05) in the choices nymph by plants. B. alata at 15 days of initial release and B. alata and grass-dictyoneura at 30 days were plants that had higher migration. All counts were carried out on 45o and 60o days, the migration of U. brizantha cv. Marandu presented significantly higher than all other species tested plants nymphs.

Comparison of apoptotic cells between cryopreserved ejaculated sperm and epididymal sperm in stallions

The development of a reliable technique to freeze epididymal semen would provide a unique opportunity to preserve valuable genetic material from unexpectedly lost stallions. The aim of this study was to compare the apoptotic indices of sperm obtained from ejaculate, sperm recently recovered from the epididymides (EP), and sperm recovered from epididymides stored at 5 C for 24 hours (EP-stored). For the first category, two ejaculates from seven stallions were collected and then submitted to cryopreservation using an egg yolk-based extender. One week after the last semen collection, the stallions were submitted to bilateral orchiectomy, and sperm from one of the cauda epididymis was harvested immediately after castration (EP). The remaining testicle was stored in a passive refrigeration container at 5 C for 24 hours before the cauda epididymal sperm was harvested (EP-stored). Sperm harvesting from the epididymis for EP and EP-stored was performed by retrograde flushing of the caudal portion of the epididymis using a skim milk-based extender. The recovered sperm was then cryopreserved using the egg yolk-based extender. Sperm motility parameters were studied by computerassisted semen analysis, and apoptosis was estimated by measuring caspase activity and membrane phospholipid translocation using epifluorescence microscopy. The samples were evaluated immediately (0 hour) and 8 hours after thawing. At 0 hour, no differences in sperm parameters were observed among the groups, but after 8 hours, significant statistical differences were observed in sperm motility parameters and plasma membrane integrity among the treatment groups. In addition, viable cells with no apoptotic signs were more prevalent in EP and EP-stored, suggesting that epididymal sperm is less sensitive to the cold shock caused by sperm cryopreservation.

Desempenho mecânico de embalagens rígidas utilizadas na indústria agroquímica: estudo de compressão

The world population is growing at exponential scales, thus the demand for food grows significantly. The use of pesticides is seen as a way to meet the demand for food and increase the efficiency and productivity of the agricultural sector. BASF SA in partnership with packaging suppliers represent a remarkable scene in the Brazilian market in the agrochemicals sector. In 2014, the Department of Agro from BASF Packaging, identified in its production process certain deformation of its rigid packaging during the filling process of pesticides. This phenomenon is probably caused by the low resistance to compression that the package is used. In order to eliminate the deformation of rigid packaging arising from the filling step, a study will be conducted in conjunction with the supplier JET UNIPAC whose on line problems occurred more frequently. The study is to identify the strength of the rigid containers standardize a compression resistance value at which the package is not deformed after the filling step. This study will present an investigation through experiments combined with theoretical concepts in order to determine possible causes for the emergence of this phenomenon. At the end of the study, a solution to eliminate or reduce to the maximum the packaging deformation problem appears
