Biologia: da natureza à cultura. Da cultura para onde?

Vivemos um momento do mundo no qual o meio foi denominado pelo geógrafo Milton Santos, como Técnico-científico-informacional. Nesse meio, a produção científica está dominada por estruturas político-mercadológicas, que para sua manutenção e existência, enxergam e tratam os elementos naturais do planeta, como recursos ou instrumentos de uso e, as pessoas, como mão-de-obra e consumidores. O abismo que separa a humanidade da natureza, é um equívoco de percepção e tem criado conseqüências sócio-ambientais que passam a ameaçar as perspectivas de futuro, não só das gerações futuras, mas das gerações atuais. A ciência moderna, ainda orientada pelo pensamento cartesiano do século XVII, a ciência que tem como marca mais forte o “só acredito, vendo”, não vê que perdeu a objetividade e não está apta a responder aos problemas do mundo contemporâneo. Até mesmo porque, muitos deles são criados e perpetuados por esse instrumento de poder manipulado pela lógica capitalista. O título desse trabalho tem como intuito incitar uma reflexão séria a respeito do rumo que estamos dando à nossa existência no Planeta Terra enquanto seres biológico-culturais, com o objetivo de inspirar mudanças interiores capazes de gerar mudanças significativas em nossa cultura. Mudanças que ao menos cheirem a esperança no que se refere às possibilidades de melhorias em nosso quadro socioambiental. Vale salientar que “O Governo”, “A Ciência” e “O Mercado”, não são entidades obscuras que assombram nossas vidas, são pessoas como nós, para não dizer “nós mesmos”. Como integrantes da populosa comunidade humana, estamos carregados de valores, crenças e condutas que influenciam direta e indiretamente a nossa vida cotidiana, em termos de hábitos comportamentais, alimentares, de relacionamento interpessoal e com toda a comunidade de vida...(Resumo completo, clicar acesso eletrônico abaixo)

Proposição de um checklist de acompanhamento de processos construtivos habitacionais em wood-frame

The need for housing in Brazil is very large, and despite government efforts to address this issue, the housing deficit is too large. When analyzing markets without this problem, it is concluded that one of the factors that influence this model is the construction adopted by Brazilian society that is in masonry. Alternatively, the system can be used in constructive Wood-frame. To apply this system in Brazil, one can say that the workmanship and the materials available to meet the demand would be created in a short period of adjustments and capabilities, but identifies himself as one of the biggest problems the planning and management of works. And one of the tools for solving this problem is to use a checklist of the activities of constructive process, avoiding forgetting or not aware of the activities necessary to complete the project

Nordeste, um estudo da estrutura econômico-social da região

Este trabalho tem como objetivo demonstrar como o Nordeste se configura como fator dinâmico no processo de desenvolvimento do sistema capitalista brasileiro.Será analisado o significado do retrocesso econômico que a região sofreu, e como isso levou o Nordeste a se tornar um fornecedor de mão-de-obra e de capital para a região centro-sul, pólo dinâmico da economia. Implica também em ver o processo de industrialização do Brasil visando à produção e a acumulação e não o consumo interno, assim o Nordeste não representa um potencial a ser trabalhado. Necessita-se então caracterizar o tipo de dinâmica existente ente a estrutura agrária nordestina e o processo de desenvolvimento industrial brasileiro, que levou o nordeste a participar ativamente desse processo

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

Sobre as considerações de uma concepção de um projeto de um forno cerâmico

The current competitiveness of the market has generated the need to minimize the cost of production companies in any field of activity, aimed at reducing the cost of production, the cost of purchasing and manufacturing processes interruption of manufacturing processes for possible maintenance. In this sense, companies are seeking methods to improve and streamline their production line. In ceramics industries, cooking the pieces is the portion of the production process that influences the total costs. The oven construction and maintenance represent a large portion embedded in the cost of the final ceramic product. The proposal for a type of oven for baking the parts that takes into account a better burning process, knowledge of the causes of disease and cost analysis of purchasing both of the constituent materials and labor for its construction, can be significant importance to the composition of final product costs or time analysis of ROI. It is proposed a streamlined design of an oven that takes into account the positive characteristics of the furnaces already built and that the experience has endorsed, and also others that are added at the end, lead to a reduction in production cost, the cost income and the number of pathologies arising from wear of the furnace along the lifespan. Therefore, according to the experiences gained over the years in the construction of furnaces and experience of manufacturing of ceramic, it is proposed a project that has an oven improvement over those now being built and that include, among other topics, economy in fuel burning, streamlining the building process

Estudo da tecnologia RFID e sua aplicação na gestão de estoques

Due to the need of more agility, dynamism and reliability in stock management, the market has turned its attention to RFID, which offers a practical solution and live up to the big corporations' expectations. The search for continuous improvement establishes a direct link with RFID, for its technology offers accurate real time information in any monitored given place. RFID is a radio frequency communication technology. A reader communicates to a tag through waves. This tag can be active, with a battery, or passive, in which its power is supplied by currents induced by the field variation it is exposed to. The RFID technology has a well defined basic principle, but there are many constructive ways of implementing it. The adaptability as well as the flexibility regard to the several kinds of stock in industry, reaching their particular needs. RFID can lower maintenance costs in stock by collecting data more accurately, lowering human error and optimizing the item handling at its reception, exit and while it is inside the company. This paper presents an example of RFID technology applied in a company's stock management. It is possible to prove that there are, in fact, great advantages in implementing this technology, as it creates the opportunity for continuous improvement in stock management, with better application of material, labour and quality tools, since the data collected through an automatized process using RFID are more reliable and dynamic

Utilização de gonadotropina coriônica equina em protocolos de inseminação artificial em tempo fixo em bovinos de corte

Current cattlemen must seek methods to maximum reproductive efficiency of their beef herds, making the business competitive and enhancing greater profitability. For the cow-calf producers, efficiency translates into more cows producing one calf every year. Fixed-time artificial insemination (TAI) is one of several technologies that producers utilize to reach this goal. Postpartum anestrus is one of the biggest obstacles to overcome in order to obtain suitable results at the end of the breeding season. The TAI protocols are efficient in re-establishing cyclicity in noncycling cows during the postpartum period, streamlining the use of labor on farms, allowing the use of artificial insemination (AI) on a large scale, and introducing superior genetics to the herd. The protocols that are most commonly used in Brazil are based on progesterone (P4) releasing devices that prevent premature estrus and ovulation; and estradiol (E2) to synchronize the initiation of a new follicular wave. In such protocols, administration of equine chorionic gonadotropin (eCG) helps the development of the follicle, increases ovulation rate, improves the endocrine and uterine environment during proestrus and diestrus, and improves fertility. The use of eCG in TAI protocols for suckled cows, non-lactating cows and heifers increases the pregnancy rate allowing more calves at the end of the breeding season and higher profitability to the cattlemen
