Recordações de um fragmento da história da imigração japonesa no Brasil

This paper proposes to investigate a specific fragment of the history of Japanese immigration to Brazil: labor relations during the period before the outcome of World War II. To this end, choosing oral history as a research method, and assumptions of historical materialism as a theoretical framework, we sought to examine the accounts of experiences remembered by a group of elderly women in this community of immigrant settlers. Theys participated both in the São Paulo coffee work in the first decades of the twentieth century, as the planting of cotton, in the 1930s.

O caminho novo: o Vale Histórico da Serra da Bocaina - opulência e decadência da sub-região paraibana paulista (reintegração de um espaço geográfico 'deprimido')

A pesquisa resgata o trecho paulista do “Caminho Novo”, antiga estrada geral de São Paulo, ligação terrestre com o Rio de Janeiro, a partir do século XVIII. No chamado Vale Histórico da Serra da Bocaina, cujo relevo se apresenta muito movimentado, a cultura do café penetrou em território paulista. Esta sub-região do Vale do Paraíba tornou-se uma das mais prósperas do país. A fase posterior, de queda na produção cafeeira, transformou-a numa região “deprimida” e estagnada. Atualmente, existem esforços para, através dos diversos ramos do turismo, reativar e dinamizar esta região vale-paraibana paulista, de modo a reintegrá-la ao pujante sistema econômico de São Paulo.

Effect of Beverages and Mouthwashes on the Hardness of Polymers Used in Intraoral Prostheses

PurposeThe mechanical properties of acrylic resins used in intraoral prostheses may be altered by frequent exposure to liquids such as beverages and mouthwashes. This study aimed to evaluate the effect of thermocycling and liquid immersion on the hardness of four brands of acrylic resins commonly used in removable prostheses (Onda Cryl, QC-20, Classico, Lucitone).Materials and MethodsFor each brand of resin, seven specimens were immersed in each of six solutions (coffee, cola, red wine, Plax-Colgate, Listerine [LI], Oral B), and seven more were placed in artificial saliva (control). The hardness was tested using a microhardness tester before and after 5000 thermocycles and after 1, 3, 24, 48, and 96 hours of immersion. The results were analyzed using three-way repeated-measures ANOVA and Tukey's test (p < 0.05).ResultsThe hardness of the resins decreased following thermocycling and immersion in the solutions. Specimens immersed in cola and wine exhibited significant decreases in hardness after immersion for 96 hours, although the greatest significant decrease in hardness occurred in specimens immersed in LI. However, according to American Dental Association specification 12, the Knoop hardness of acrylic resins for intraoral prostheses should not be below 15. Thus, the median values of superficial hardness observed in most of the acrylic resins in this study are considered clinically acceptable.ConclusionsThe microhardness of polymers used for intraoral prostheses decreases following thermocycling. Among specimens immersed in beverages, those immersed in cola or wine experienced the greatest decrease in microhardness. Immersion of acrylic resins in LI significantly decreased the microhardness in relation to the initial value. Among the resins assessed, QC-20 exhibited the lowest initial hardness.

Recuperação de áreas degradadas por erosão hídrica em propriedades produtoras de café nos municípios de Getulina e Vera Cruz - SP

The Paulista West region has suffered through the decades an intense process of deforestation when substituting native areas of Atlantic rainforest and Cerrado by agricultural cultivation, mainly coffee in the 20th century. This occupation process without planning and management of the soil resulted in serious erosion problems. Besides, the soil erosion promoted the reduction of agricultural production and the silting of rivers. This paper aims identify the factors of natural scope (geological, geomorphologic and pedologic characteristics) which participate in unleash of erosion process in two agricultural properties producers of coffee in order to apply mechanical techniques of recovery in erosive focuses of furrow and ravine kinds. One of the properties is at the city council of Getulina, located on the sandstones of Adamantina Formation; the other is at the city council of Vera Cruz, located on the sandstones of Marília Formation. However, taking into consideration the analysis of the natural dynamics, they are not enough to explain the complexity of the phenomena which are processed in the geographic space. It made indispensable the incorporation of socio-economic factors, such as the use and occupation process of the soil considering the society as landscape transformers. In order to better understand the importance of each one of the elements that contributes to the unleash of the studied erosions, it was collected soil samples in the areas, general descriptions and texture and morphologic analysis. Finally, it was elaborated the maps of the use and occupation of the soil and the vegetal coverage surrounding the properties studied. It was observed in the rural property of Getulina the substitution of the coffee by pasture that finds degraded. It, in addition to the cattle stomp, which changed the texture and density characteristics among the soil horizons, and the concentration of superficial water flow intensified the occurrence of ...

Circuito espacial produtivo e círculos de cooperação dos café Fairtrade: análise da Associação dos Agricultores familiares do Córrego D'Antas (ASSODANTAS), Poços de Caldas/MG

The aim of this research project is to analyze the spatial productive circuit and circles of cooperation of Fairtrade coffee, taking as a case of study the Associação dos Agricultores Familiares do Córrego D'antas (ASSODANTAS), Poços de Caldas - MG. The main purpose is to analyze material flows (grains, supplies, etc.) established between geographically separated stages of production (production, exchange, distribution and consumption) and the relationships between the agents in order to analyze the organization and regulation of production of Fairtrade coffee. It is understood as the insertion of the Fairtrade ASSODANTAS to permit the creation of new production lines, adding value and providing greater identity and autonomy to their small farms, when compared with traditional coffee trade commodity

Sistemas técnicos agrícolas e cafeicultura científica globalizada no sul de Minas Gerais

The study aims to analyze the mechanization of the main coffee growing region in the south of Minas Gerais, in force, especially from the 1970s. But you get new content from the1990s, with the introduction of new information technologies. The use of machines in production processes appear as one of the great transformations of coffee in the period modern after globalization, requiring a labor more specialized, although resulting in unemployment in rural areas. So in the period of globalization new technologies gradually replace manual work. In the coffee farm, the old ways of the production (that handed down from father to son) aren't accepted by the global scientific agriculture (Santos, 2000:88). They are considered inefficient and low quality, but not attendant of patterns the international market. The national companies producing agricultural machines for coffee with emphasis on the company Pinhalense Agricultural Machinery SA believe that the producers of the region are its biggest customers in the country, considering the degree of mechanization more pronounced compared to other coffee growing regions. Analyze the importance of the coffee region with a contribution in the indicators of export and trade surplus in the Brazil and State of Minas Gerais

Modelagem matemática para a dispersão de fungos fitopatogênicos via autômatos celulares

Brazil is a major world producer and exporter of agricultural products like soybeans, sugar, coffee, orange and tobacoo. However, the action of phytopathogenic fungi has been one of the largest challenges encountered in the field as they are responsible for approximately 25 to 50 per cent of losses in crops of fruits and vegetables. The presence of these pathogens is always a problem, because the damage on the tissues and organs promote lesions which decreses growth vegetation and often leads the individual (host) to death. Therefore, it is crucial to understand the process of spreading of these pathogens in the field to develop strategies which prevent the epidemics caused by them. In this study, the dispersal of fungi phytopathogenic in the field was modeled using the automata cellular formalism. The growth rate of infected plants population was measured by the radius of gyration and the influence of host different susceptibility degrees into the disease spread was assessed. The spatial anisotropy related to the plant-to-plant space and the system’s response to distinct seasonal patterns were also evaluated. The results obtained by a mean field model (spatially implicit models) emphasized the importance of the spatial structure on the spreading process, and dispersal patterns obtained by simulation (using a cellular automata) were in agreement with thse observed in data. All computational implementation was held in language Cl
