Dendrobium is a large genus in the family Orchidaceae that exhibits vast diversity in floral characteristics, which is of considerable importance to orchid breeders, biotechnologists and collectors. Native species have high value as a result of their medicinal properties, while their hybrids are important as ornamental commodities, either as cut flowers or potted plants and are thus veritable industrial crops. Thus, preservation of Dendrobium germplasm is valuable for species conservation, breeding programs and the floriculture industry. Cryopreservation represents the only safe, efficient and cost-effective long-term storage option to facilitate the conservation of genetic resources of plant species. This review highlights 16 years of literature related to the preservation of Dendrobium germplasm and comprises the most comprehensive assessment of thorough studies performed to date, which shows reliable and reproducible results. Air-drying, encapsulation-dehydration, encapsulation-vitrification, vitrification and droplet-vitrification are the current cryopreservation methodologies that have been used to cryopreserve Dendrobium germplasm. Mature seeds, pollen, protoplasts, shoot primordia, protocorms and somatic embryos or protocorm-like bodies (PLBs) have been cryopreserved with different levels of success. Encapsulation-vitrification and encapsulation-dehydration are the most used protocol, while PLBs represent the main explant explored.

This study aimed the geological characterization at scale 1:50.000 of an area belonging to the southern sector of the Brasilia Belt, located in the western portion of the Passos Nappe, near the town of Cássia, MG. In this region, outcrops rock types belonging to Araxá Group, composed of metasediments associated with metavolcanics which form a tectonometamorphic terrain of great importance for understanding the geological evolution of southeast and midwest regions of Brazil. With the development of work was possible to group the rocks in 10 lithostratigraphic units and had been identified 3 different zones of metamorphism generated during the peak metamorphism. The structural pattern of the area shows that the main foliation has average dip 30 ° NW and mineral lineation parallel to the stretching direction with 290 °. Still, we can conf irm that this inverse gradient metamorphic rocks of the Passos Nappe, described by several authors. Also, were seen lithotypes of economic interest, some already in exploitation, such as clay and sand, and other mineral commodities, which are occurring and can be used: quartz, quartzite, garnet, kyanite, rutile and zircon.

A indústria de transformação é considerada de suma importância para o desenvolvimento do país tanto em termos econômicos como sociais, visto que é responsável por encadeamentos produtivos e efeitos multiplicadores no emprego e na renda do país. Entre os anos de 2000 e 2011 ainda que haja indícios de desindustrialização da economia brasileira, devido à queda da participação do valor adicionado da indústria de transformação no Produto Interno Bruto e à deterioração da indústria de transformação frente ao comércio exterior, no que concerne ao emprego, em termos absolutos e relativos, não há suspeitas de que esteja em curso no Brasil um processo de desindustrialização. Paralelamente, ressalta-se que embora se façam presentes sintomas da chamada “doença holandesa” no Brasil, ou seja, balança comercial superavitária em commodities acompanhada de déficits da indústria de transformação e de taxa de câmbio valorizada; o Brasil não parece sofrer da “doença”

Com elevadas taxas de crescimento e participação cada vez maior no comércio mundial, a China intensifica suas relações com o Brasil e com a América do Sul, na qual apresenta-se como exportadora de manufaturados e importadora de commodities. Os efeitos desta relação devem ser estudados com cautela, pois apesar dos ganhos de curto prazo, geram perigosos impactos a médio e longo prazo. No Brasil, a presença chinesa é uma ameaça imediata ao setor industrial tanto no mercado interno, quanto externo

The researches on sexuality, especially from Foucault’s critical analysis, have been denouncing that the sexual repression also happens through the patterns that suggest a fixed happiness model to be followed, not considering the autonomous development of the subject. The aim of this descriptive-qualitative study was to make a critical analysis of the content of the book Sex and The City, which presents narratives about sexual and love relationships in New York. This analysis evidenciated the reproduction of outdated sexual concepts presented on the following thematic categories: (1) Comprehension of the single woman as lonely and unhappy; (2) Comprehension of the single woman as independent and consumerist; (3) Comprehension that the single woman needs a heterosexual relationship related to the happy romantic ideal; (4) Comprehension of the love relationships as commodities: people as objects of use and exchange. The sexual and love patterns presented by the book demonstrate the repression reproduced uncritically by the mass culture. The Psychology has been an important area of the science to denounce the control of the sexuality from these perverse and ideological patterns.
