Quali-Quantitative Analysis of Brazilian Environmental Licensing of Hydropower Plants  [PDF]
Fabio Giusti Azevedo de Britto, José Paulo Soares de Azevedo, Cynara Alets Sthuasth Souza de Melo Frana, Rodrigo Cunha Wanick, Leandro Andrei Beser de Deus, Marcos Aurélio Vasconcelos de Freitas
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.67056
Abstract: The use of the extraordinary hydroelectric potential of the Amazon Basin originated an increase in the offer of renewable energy in Brazil, which, in its turn, leads to conflicts and a lack of consensus among different players owing to the potential negative impacts related to the construction and operation of large hydroelectric power plants in relatively well preserved areas. In this context, environmental licensing is one of the national environmental policy’s main instruments for making decisions regarding the use of the hydroelectric potential, especially the rivers of the Amazon Basin. Nevertheless, this significant instrument has its limitations and requires adjustments in order to better aid the decision making process regarding the use of water resources and land with the goal of increasing the offer of electric energy.

Abstract: the grasshopper species orthoscapheus rufipes and eujivarus fusiformis were analyzed using several cytogenetic techniques. the karyotype of o. rufipes, described here for the first time, had a diploid number of 2n = 23, whereas e. fusiformis had a karyotype with 2n = 21. the two species showed the same mechanism of sex determination (xo type) but differed in chromosome morphology. pericentromeric blocks of constitutive heterochromatin (ch) were detected in the chromosome complement of both species. cma3/da/dapi staining revealed cma3-positive blocks in ch regions in four autosomal bivalents of o. rufipes and in two of e. fusiformis. the location of active nors differed between the two species, occurring in bivalents m6 and s9 of o. rufipes and m6 and m7 of e. fusiformsi. the rdna sites revealed by fish coincided with the number and position of the active nors detected by agno3 staining. the variability in chromosomal markers accounted for the karyotype differentiation observed in the tribe abracrini.

Abstract: this study analyzed the causes of delay in the diagnosis of tuberculosis in the prison system, according to the experience of incarcerated patients. the theoretical and methodological framework of the french school of discourse analysis was used, which seeks to comprehend the processes of meaning production, in the relationship of language with ideology and the development of subjects in their positions. semi-directed interviews were conducted with seven incarcerated tuberculosis patients in a hospital of jo?o pessoa, paraíba, brazil, between august and october 2009. the delay in the diagnosis of tuberculosis was related to the naturalization of the lack of care for the prisoner, to the interpretation of the prison as a place of death and suffering and to the deprivation of the right to health for the detainees as a result of their position in the asymmetric power relationships and ideological effects.

Abstract: Chagas disease is caused by infection with the intracellular protozoan parasite Trypanosoma cruzi. At present, nifurtimox and benznidazole, both compounds developed empirically over four decades ago, represent the chemotherapeutic arsenal for treating this highly neglected disease. However, both drugs present variable efficacy depending on the geographical area and the occurrence of natural resistance, and are poorly effective against the later chronic stage. As a part of a search for new therapeutic opportunities to treat chagasic patients, pre-clinical studies were performed to characterize the activity of a novel arylimidamide (AIA - DB1831 (hydrochloride salt) and DB1965 (mesylate salt)) against T.cruzi. These AIAs displayed a high trypanocidal effect in vitro against both relevant forms in mammalian hosts, exhibiting a high selectivity index and a very high efficacy (IC50 value/48 h of 5–40 nM) against intracellular parasites. DB1965 shows high activity in vivo in acute experimental models (mouse) of T.cruzi, showing a similar effect to benznidazole (Bz) when compared under a scheme of 10 daily consecutive doses with 12.5 mg/kg. Although no parasitological cure was observed after treating with 20 daily consecutive doses, a combined dosage of DB1965 (5 mg/kg) with Bz (50 mg/kg) resulted in parasitaemia clearance and 100% animal survival. In summary, our present data confirmed that aryimidamides represent promising new chemical entities against T.cruzi in therapeutic schemes using the AIA alone or in combination with other drugs, like benznidazole.
