Psychosocial Identity of the adolescents in boarding school system in the agricultural education Abstract: This article is the result of a research where we try to study and to understand the psychosocial identity of adolescents undergoing boarding. We discussed the issue of boarding school in literature and notes about adolescence in various psychological approaches. Research strategies were interviews, and focus group reports. We conclude that, even with the difficulties students believe that the promising future can only be achieved through technical training, which would enable them not only to acquire a knowledge, but also as a way to gain access to a better-paying job. A better understanding of the surrounding reality allows us to subsidize various professional institutions also adopt boarding as an option to stay.

O objetivo do presente trabalho consiste em explorar as formas de mensuração do desenvolvimento econômico, surgidas nas últimas décadas, bem como a ampliação dos fatores que o analisam para além de mero crescimento do produto. Assim, é feita uma discussão a respeito do surgimento de índices e indicadores, que passaram a considerar fatores como bem-estar, qualidade de vida e proteção ao meio ambiente, mudando a análise de meramente quantitativa para uma análise qualitativa do desenvolvimento. Além disso, para que se tenha mais clareza a respeito do desenvolvimento, bem como dos indicadores que buscam qualificá-lo, o trabalho busca esclarecer as abordagens de desenvolvimento tradicionais e seus respectivos indicadores - desde o PIB até os alternativos, como o FIB

Apresentando uma síntese histórico-sociológica do panorama rural brasileiro, da constituição do ensino técnico, e do desenvolvimento do ensino técnico agrícola, este artigo defende que as escolas técnicas agrícolas sofrem uma dupla marginalização, por um lado proveniente de sua natureza profissionalizante e, por outro, dada sua vinculação com o meio rural brasileiro.

The study took place in a sewage treatment plant located at the actual Department of Water and Sewer in Bauru, city of Sao Paulo state. This treatment plant has an average entrance flow of 4.8 l. s-1 made by upflow anaerobic filter, followed by wetland systems constructed in parallel. . As objective of this study we evaluate the effectiveness of three systems of constructed wetlands, with three different types of plants (Lily pond, Giant papyrus and Cattail),quantify, and qualify the effluents at various stages of treatment to monitor their effectiveness and the possibility of reuse in agriculture. There was a satisfactory removal of organic matter, with a mean concentration of 36 and 39mg.l-1 at the , phases 1 and 2 of the operation, respectively. The constructed wetlands effluent nitrogen and phosphate concentrations were high throughout all the system and the removal efficiency of ammonia nitrogen was much lower than expected, then the system is functioning as secondary treatment and not as tertiary treatment. The concentrations of micro-organisms found in the final effluent were also high. Therefore, it is concluded that the results of removal efficiency of organic matter, of constructed wetland systems, meet the parameters required by legislation for effluent discharges but do not attend the parameters required for nitrogen and micro organisms. This way, these analyzed plants effluents are suitable for reuse in agriculture restricted irrigation

This work aims to characterize and analyze the development and modernization of the Brazilian agricultural sector in the period from 1960 to the end of the Lula government, through the military dictatorship, the plans to combat inflation in the 1980s and 1990s and the programs social Lula's government. The performance of commercial agriculture is emphasized in the FHC and Lula administrations

The multivariate analysis grouping was used to characterize the productive and climate profile of southeastern of Mato Grosso state. This technique allowed the junction of similar micro regions from characteristics of productivity and climatic, without the need for the assumption of the number or structure of the groups. Cluster analysis allowed the design of a mosaic of spatial heterogeneity regions. It established different profiles in the composition of groups, joining the more traditional in the culture of a species, or more productive, or those for the development of a particular culture. The results obtained by estimation of the climatic parameters and the multivariate procedures enabled the provision of systematic information that will allow farmers to better decision-making on the competitiveness and maintaining the flow of investment in agricultural sector southeastern Mato Grosso.

Maintenance of agricultural diversity in rural settlements – a case study in Moji-Mirim, São Paulo, Brazil. This paper investigated whether farmers, when established in rural settlements, keep some traditional features with regard to crops diversity and circulation of planting material. Its aims were to make an ethnobotanical survey of species and varieties and analyze the dinamics of seeds and propagules circulation. A total of 139 varieties of food crops (55 species/28 families) were found, being 87% of them intended for self-consumption; 54% of varieties come from Minas Gerais, home state of most respondents. The number of varieties grown per household ranged from 17 to 54. The informal and free circulation of planting material is the most important way of acquisition. The circulation network is very active, showing a potential for the management of crops diversity, with emphasis on the contribution of settlers to the maintenance and valorization of traditional varieties.

A produção de alimentos e matérias-primas é considerada um dos maiores desafios da atualidade. Assim, os impactos gerados pela atividade da agricultura são muitos, como por exemplo, erosão dos solos, poluição de águas doces e geração de resíduos. Com isso faz-se necessário o desenvolvimento de tecnologias para promover a redução desses impactos. O presente trabalho tem como objetivo apresentar e discutir análises energéticas em sistemas de produção agrícola como uma ferramenta capaz de destacar a dependência dos agroecossistemas de energia externa e de fontes não renováveis, particularmente de fontes fósseis. Assim, com o uso dessa ferramenta, alternativas para uma produção agrícola com menos impacto ambiental pode ser alcançada, proporcionando a ampliação das possibilidades para uma produção mais sustentável.

Agricultural mechanization improved the efficiency of field operations by providing an increase in crop production. The intensified mechanization, however, has led to higher energy use mainly in the area of fuel consumption. The objective of this study was to compare the fuel consumption of tractors using two different tire pressures for two different types of soil during tillage with irrigated cotton in semi-arid regions. These tests were performed at the Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona with a Case 4x2 TDA 88kW equipped with an autopilot system. The results showed lower fuel consumption using a tire pressure of 124 kPa on sandy clay loan soil.

Currently, the efficiency in field operations and the increased productivity of crops is only possible with the use of agricultural machinery and equipment. This intensification of mechanized activities in agriculture, however, led to higher energy costs on farms mainly in the fuel consumption of agricultural tractors. The objective was to compare the fuel consumption of a tractor on tillage operations for irrigated cotton in semi-arid region varying two tire inflation pressures. The tests were conducted in Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona using a 4x2 TDA Case tractor equipped with a 88kw autopilot system. The results showed lower values in the hourly fuel consumption by using the minimum tire inflation pressure of 124 kPa for all tillage equipment used.
