Yamadazyma riverae sp. nov., a yeast species isolated from plant materials

Nine strains of a novel yeast species were isolated from rotting wood, tree bark, ant nests or living as endophytes in leaves of Vellozia gigantea. Analysis of the sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit rRNA gene showed that this species is related to Candida insectorum in the Yamadazyma clade. The new species differs from its closely related species by 10 and 11 substitutions in the ITS region and the D1/D2 domains of the large subunit of the rRNA gene, respectively. The species is heterothallic and forms asci with one to two hat-shaped ascospores. The name Yamadazyma riverae sp. nov. is proposed. The type strain of Yamadazyma riverae sp. nov. is UFMG-CM-Y444T (= CBS 14121) and the allotype strain is TT12 (= CBS 14098 = UFMG-CM-Y577). The Mycobank number is MB 813221.

A pesquisa em televisão digital no Brasil: apontamento sobre o levantamento bibliográfico realizado de 1995-2008 sobre o assunto

In Brazil, the discussion about thereplacement of analog television signals to digitaland its impact on society, in media companies andgovernment began in the 90s. Embryonic steps towardsdigitalisation of the television signal ground were thegovernment of Fernando Collor de Mello (1990-1992),with advances during the government of FernandoHenrique Cardoso (1994-2001) and in the governmentof Luiz Inacio Lula da Silva (2002). The academy startsthe discussion in 1996. This article aims to bring to lightthe results obtained from the survey Digital television:a historical perspective , which received the supportof CNPq for funding of two scholarships for scientifi cinitiation between August 2008 and July 2009. Theproject sought to identify what has been published onthe subject in the fi eld of Social Sciences and from threemacrodescritores (information management, publicpolicy and value chain), providing the li ing of a virtualcollection Zotero bibliographic innovative platform.The mapping serves to show the growing interest anddevelopment of research in the country during theperiod - when the number jumped to three works inthe fi rst seven years (1995-2001) to 198 in the last sevenyears (2002-2008). The research sought to identify themajor authors and works related to digital televisionand published in the country. The survey took intoaccount books, articles published in books, journals,Annals of Compós and Intercom, and dissertations andtheses. Data and refl ections on the survey are containedin this communication.

Aprendizagem significativa do conceito de ressonância

In this research work we verified the interaction between teacher and students through the use of reading an alternative text, the use of an experimental activity demonstration and presentation of videos involving the concept of resonance in a room on the 3rd year of teaching medium, led to meaningful learning of that concept. The instruments for the creation of data were based on audio and video records, taken during the lecture and the written evaluations performed by the students two weeks later. The results showed that this interaction, mediated by the use of these resources, led to meaningful learning of the concept of resonance. It was also possible to observe the students' motivation to participate actively in class.

Fernando Henrique Cardoso e a dependência da região Amazônica

The goal for this research is to analyse the thinking of Fernando Henrique Cardoso (FHC), to understand his vision about underdevelopment nations and his teses about dependence, in order to comprehend its consequences of his the thinking for the Brazil and primarily to the brazilian Amazon region. Considering that the penetration geographical on Amazon and the history of the region make part of the totality of the process on expansion of the capitalism, in his form, function, rythm and volume of the accumulation occurred also in the other regions of the Brazil (and abroad), we have to study it in this way, showing that is a totality. Then to understand the actions of Cardoso as president, mainly on this region. Bringing this discussion to the social function of the corporations and the many faces of underdevelopment

Viabilidade econômica do uso do biogás proveniente da suinocultura em substituição a fontes externas de energia

The swine culture potentially generates waste with high organic load and pollutants, being responsible for the spread of pathogens, contamination of rivers, groundwater and soils, besides it produces foul odors and emit greenhouse gases. However, the high amount of organic matter, which expresses the amount of pollutant load, reflects the energetic potential of these wastes used as raw material in biogas generation through technology of digesters. The properly use of theses digesters provides the production of clean energy and promotes the conservation of the environment. The economic viability of the implantation of an Indian model digester on a small swine farm was verified based on the value from initial investments of deployment, maintenance costs, depreciation, and on the interest and revenues arising from the system. Besides, the amount of biogas produced daily and the average consumption of biogas by the most common used devices such as refrigerator, stove, water heater, and generator of electricity was calculated.. For a backdrop of 10 years, the results of economic indicators NPV of BRL 57,598.95, IRR of 48.38%, Simple Payback of 2.06 years, and Discounted Payback of 2.3 years, demonstrated a favorable outlook for the use of this technology, with the possibility to generate economic, social and environmental benefits.
