Hemerobiidae (neuroptera) in the midwestern region of minas gerais state, Brazil

This study aimed to identify the Hemerobiidae (Neuroptera) associated to Brazilian savannah and gallery forest, in Minas Gerais State, Brazil. The sampling was carried every two weeks at Brazilian savannah (Cerrado) in Divinopolis and at gallery forest in Pedra do Indaia, both in Minas Gerais State, Brazil. Collecting was carried out between November 2003 and October 2004, with Malaise traps. A total of 181 specimens of five species of Hemerobiidae were collected. The species Nusalala tessellata, Megalomus impudicus, Hemerobius bolivari and Notiobiella sp. were collected in the two sites; the fifth species Sympherobius sp. was found only in Pedra do Indaia. The species of diversity (index of Shannon-Wiener) and the equitability (J) of Hemerobiidae were similar in the areas of Brazilian savannah and gallery forest (H'=0.47-0.49, respectively, and J=0.78-0.69, respectively), and the differences observed between the two locations were not significant.

Caracterização molecular de Cryptosporidium spp. em bezerros (Bos taurus e Bos indicus) no município de Formiga, Minas Gerais - Brasil

A criptosporidiose, é a enfermidade de veiculação hídrica, possui como agravante a dificuldade de prevenção da contaminação ambiental e ausência de medidas terapêuticas eficazes. Com acentuada importância na bovinocultura, ocasiona inflamação e atrofia das vilosidades intestinais resultando em perda da superfície de absorção. Este estudo teve como objetivo realizar a caracterização molecular da infecção por Cryptosporidium spp. em bezerros do Município de Formiga, Minas Gerais. Um total de 300 amostras de fezes de bezerros holandeses, Nelore e sem raça definida saudáveis foram avaliadas pela técnica de coloração contraste negativo de verde malaquita e por meio da reação de Nested-PCR para amplificação de fragmentos de DNA da subunidade 18S do gene do RNA ribossômico. Ocorrência de 5,33% (16/300) pelo verde malaquita e 4,66% (14/300), pela PCR foi observada, sendo que nenhuma correlação foi verificada entre a positividade e as variáveis estudadas. Por meio da caracterização molecular foram identificadas as espécies Cryptosporidium andersoni e Cryptosporidium ryanae. Como conclusão, observou-se baixa ocorrência da infecção e eliminação de oocistos por Cryptosporidium spp, ausência de sinais clínicos nos animais, houve forte concordância entre os resultados obtidos por meio das duas técnicas utilizadas e pela caracterização molecular (Nested-PCR) foram diagnosticadas as espécies C. andersoni e C. ryanae, presentes em faixas etárias não relatadas na literatura. Estas duas espécies de Cryptosporidium supracitadas são descritas pela primeira vez, parasitando bovinos no estado de Minas Gerais.

Estudo geofísico em um depósito de manganês supergênico no município de Itapira - SP

The mining research is a complex activity, which should preferably involve the combination of direct and indirect techniques of geological research. The increasing demand for base metals in domestic and international markets provide the revaluation of mineral occurrences, which can be converted into deposits and mines. This paper presents the results of the application of geophysical methods of electric resistivity and induced polarization in main foliation parallel to the arrangement of the area, in a deposit of oxides and hydroxides in massive and disseminated ores, docked in gneisses and quartzites, located in the municipality of Itapira, in the North of the State of São Paulo in Brazil. Inversion models indicate the predominance of high cargabilidade that partially coincide with low resistivity values. Integration of geophysical data made possible the drafting of sections of electric walking with cross-checking distance x depth, for detailing your target. The integrated analysis of geophysical and geological structural data leads to the conclusion that the primary mining suffers structural control with the regional foliation in ores

Fácies e associação de fácies da formação Pirambóia na região de Descalvado/SP

The Pirambóia Formation is a lithostratigraphic unit of the Paraná Basin, positioned between the Corumbataí (lower) and Botucatu (upper) Formations on the eastern edge of the basin. This unit is focused by many studies due to its great importance as an essential component in the Guarani Aquifer System (SAG) and the petroleum system “Irati-Pirambóia”, as excellent reservoirs. The Pirambóia Formation is historically the subject of several controversies on issues like age, contact relationships with the upper unit and depositional paleoenvironment. Despite these aspects, the Pirambóia Formation is commonly taken to be of Triassic age and is considered a product of wet aeolian systems, with plenty of wet interdunes and subordinate fluvial facies. In this work, by using techniques such as facies analysis, depositional architecture and facies association, facies of this unit were characterized and their depositional paleoenvironment was inferred particularly in Jundu Mining, region of Descalvado in northeastern São Paulo. Techniques such as grain size and petrographic analyses, aimed to characterize this unit as a potential reservoir rock. Five facies were described for the Pirambóia Formation in the studied region: St, Sh, Sm, Sr and Gt facies, generated by sedimentary processes of the bottom load type, mostly under low flow regime (with exception for the Sh facies, which is formed by upper flow regime processes). In addition to that, four facies associations were recognized from the architectural elements, primarily contained within the main channel: complex channel bars, composed by foreset macroforms (FM), sandy bedforms (SB) and gravel bars and bedforms (GB); flood deposits, constituted by laminated sand sheets (LS); deposits of hyperconcentrated flows and eolian deposits. It was interpreted that the Pirambóia Formation in Descalvado (SP) is the record of the sedimentation of braided rivers, with dunes and interdunes deposits...

O valor da elaboração de relatórios de sustentabilidade para as empresas de mineração

Sustainability has been moving up on the business agenda in recent decades, and many methods to assess corporate sustainability have already been created. One of the most used and reliable methods is the Sustainability Reporting Guidelines of the Global Reporting Initiative (GRI). Given the importance of sustainability for society and organizations, this study examined sustainability reports published by mining companies – Alcoa, Vale and Samarco – since 2006. The objective was to verify the indicators that contribute most to the minimization of environmental impacts and the improvement of environmental performance. The methodology consisted of collecting and analyzing data from the GRI sustainability reports. It was discovered that the sustainability reports helped the companies to identify improvement opportunities and it is essential companies provide in their reports an economic, environmental and social context of their activities. Furthermore, it was found out that the indicators related to atmospheric emissions, solid waste generation, environmental protection expenditure, and the consumption of raw materials, energy and water are the ones more attached to the production process, which means they are the main contributors for the environmental performance improvement

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
