Abstract: Em vários romances de Jo o Gilberto Noll o tempo assume papel preponderante. O passado é quase sempre negado ou dissimulado. O futuro é vago, pois n o há esperan as e tudo é precário. O mediato, o presente, é que rege as narrativas, orquestrando todo o conjunto ao seu redor. Como os personagens erram sem destino, s o muito vulneráveis. Dessa forma, a morte está constantemente à espreita.

Abstract: The influence of xenobiotic compounds on environment and on living organisms has been reported as an imminent public health problem. Among them we can list the contamination by Alkanes present in petroleum, hydrocarbons and organic contaminant substances from industrial effluents. Also, heavy metals are of particular interest because of their persistence in the environment contaminating the food webs. Among the innovative solutions for treatment of contaminated water and soil is the use of biological materials like living or dead microorganisms. Yeasts exhibit the ability to adapt to extreme condition such as temperature, pH and levels of organic and inorganic contaminants that make them a potential material to be used to remediate contaminated environment application. The goal of this work was to search for yeast isolates capable to use n-hexadecane (alkane hydrocarbon) as a primary carbon source and for those able to tolerate high concentration of lead (Pb) within a collection of 90 isolates obtained from the Sao Paulo Zoo composting system. The isolated yeast strains were identified by mass spectrometry (MALDI-TOF-MS) and by sequencing of the ribosomal DNA (18S and D1/D2) conserved regions. We found that the collection bares 23 isolates capable of utilizing n-hexadecane and one which is able to tolerate high concentration of lead (Pb) with a high biosorption index compared to the reference yeast strains (BY4742, PE-2, CAT-1 and BG-1). These results confirm the initial hypothesis that the Sao Paulo Zoo composting is the source for diverse yeasts species with biotechnological application potential.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0046142
Abstract: Background Brazil is the world's largest producer of sugarcane. Harvest is predominantly manual, exposing workers to health risks: intense physical exertion, heat, pollutants from sugarcane burning. Design Panel study to evaluate the effects of burnt sugarcane harvesting on blood markers and on cardiovascular system. Methods Twenty-eight healthy male workers, living in the countryside of Brazil were submitted to blood markers, blood pressure, heart rate variability, cardiopulmonary exercise testing, sympathetic nerve activity evaluation and forearm blood flow measures (venous occlusion plethysmography) during burnt sugarcane harvesting and four months later while they performed other activities in sugar cane culture. Results Mean participant age was 31±6.3 years, and had worked for 9.8±8.4 years on sugarcane work. Work during the harvest period was associated with higher serum levels of Creatine Kinase – 136.5 U/L (IQR: 108.5–216.0) vs. 104.5 U/L (IQR: 77.5–170.5), (p = 0.001); plasma Malondialdehyde–7.5±1.4 μM/dl vs. 6.9±1.0 μM/dl, (p = 0.058); Glutathione Peroxidase – 55.1±11.8 Ug/Hb vs. 39.5±9.5 Ug/Hb, (p<0.001); Glutathione Transferase– 3.4±1.3 Ug/Hb vs. 3.0±1.3 Ug/Hb, (p = 0.001); and 24-hour systolic blood pressure – 120.1±10.3 mmHg vs. 117.0±10.0 mmHg, (p = 0.034). In cardiopulmonary exercise testing, rest-to-peak diastolic blood pressure increased by 11.12 mmHg and 5.13 mmHg in the harvest and non-harvest period, respectively. A 10 miliseconds reduction in rMSSD and a 10 burst/min increase in sympathetic nerve activity were associated to 2.2 and 1.8 mmHg rises in systolic arterial pressure, respectively. Conclusion Work in burnt sugarcane harvesting was associated with changes in blood markers and higher blood pressure, which may be related to autonomic imbalance.
The concentric critique. Schlosser’s Kunstliteratur and the paradigm of style in Croce and Vossler
Ricardo di Mambro Santos
Journal of Art Historiography , 2009,
Abstract: The essay analyzes the philosophical and methodological premises of Julius von Schlosser’s most important contribution in the field of art historiography: Die Kunstliteratur, published in Vienna in 1924. It examines Schlosser’s adoption of paradigms drawn from Croce’s aesthetics and Vossler’s linguistics in order to understand his radical shift from a positivistic method of research to an idealistic conception of the critique as a verbal (repeatable) evocation of the visual (unrepeatable) experience of art. According to Schlosser, works of art, given their relation to intuition, should not be considered potential objects of knowledge, but more appropriately vehicles for an inner, spiritual transformation. Since the “purest essence” of art cannot be reached beyond the “unique moment” of aesthetic experience, Schlosser’s critique no longer tries to analyze the “real centre” of a work of art – namely its “artistic” values – but limits itself to the description of the material conditions closely related to its creation. By means of a “concentric” approach, Schlosser thus investigates any element that belongs to the “historical grammar” of a “language”, giving up any conscious attempt to determine the real “centre” of a work of art, i.e. the untranslatable beauty of its “style”.

Revista de Administra??o Pública , 2011, DOI: 10.1590/s0034-76122011000600004
Abstract: Este artigo apresenta os resultados de uma pesquisa que teve o objetivo de analisar as a es estratégicas realizadas por uma empresa estatal do setor elétrico brasileiro (SEB) e que levaram à mudan a estratégica na organiza o durante o período 19902004. Para a consecu o do objetivo, foram utilizadas as dimens es de contexto, conteúdo e processo, sugeridas por Pettigrew (1987) para pesquisas sobre mudan a estratégica. A pesquisa caracteriza-se como um estudo de caso qualitativo com uma perspectiva de análise longitudinal. Os dados foram coletados por meio de entrevistas, observa o direta e análise documental. P de-se concluir que o período que esta pesquisa contemplou foi de grande turbulência para o SEB e também para a firma, fazendo com que várias mudan as surgissem para modificar o comportamento estratégico da empresa e a sua competitividade, reveladas pela intera o dinamica entre contexto, conteúdo e processo. Embora a empresa fa a parte de um ambiente altamente institucionalizado, que normalmente caracteriza o determinismo ambiental inerente ao SEB, a mudan a estratégica na organiza o também ocorreu por meio de um processo voluntarista, caracterizado pela inten o gerencial de guiar o processo de mudan a. This article presents the results of a research that aimed to analyze the strategic actions undertaken by a state enterprise of the Brazilian electric sector which led to strategic change in the organization during the period comprised between 1990 and 2004. In this way, were used the dimensions of context, content and process, as suggested by Pettigrew (1987) for research on strategic change. The research is characterized as a qualitative case study with a longitudinal perspective of analysis. Data were collected through interviews, direct observation and document analysis. It was concluded that the period analyzed in this research was very turbulent for the sector and also for the company, which led to several changes that modified the strategic behavior of the company and its competitiveness, revealed by the dynamic interaction between context, content and process. Although the company is part of a highly institutionalized environment, which normally characterizes the environmental determinism inherent in the Brazilian Electricity Sector, the strategic shift in the organization also occurred through a deliberate process, characterized by the managerial intention to guide the change process.
