Peres, Andréa Carolina Schvartz;
Cadernos Pagu , 2011, DOI: 10.1590/S0104-83332011000200005
Abstract: the war in bosnia and herzegovina ethnically organized territories and redefined the ethno-national categories and groups - serbs, croats and bosnians (muslims). beside the battles between soldiers at the front lines, several atrocities used to happen in other fields: homes, villages, cities, detention places, concentration camps, and the rape camps. this article introduces the debate about the rapes that occurred during the war in bosnia and the ways to understand them: as a war weapon, as an ethnic cleansing tool, as an attempt to extermination.
Imaginaire acoustique et apprentissage d’une ontologie animiste Acoustic imagination and the learning of an animistic ontologyThe case of the Quechua of Peruvian Amazonia

Ateliers d'Anthropologie , 2010, DOI: 10.4000/ateliers.8553
Abstract: Cet article examine le r le de l’imitation sonore au sein des pratiques et des représentations de la chasse et de la maladie chez les Quechua d’Amazonie (Pastaza, Pérou). L’analyse se fonde sur un ensemble de récits qui mettent en scène une interaction avec les ma tres du gibier dans un contexte ordinaire ou rituel. Partant de la description des techniques de chasse au leurre, l’auteur montre la pertinence d’un mode de communication fondé sur la simulation sonore au sein des interactions contr lées et incontr lées avec les entités tutélaires du gibier (récits d’initiation cynégétique ou biographies de rencontre d’esprit). Après avoir montré la cohérence de ce schéma dans la sphère de la praxis cynégétique, l’auteur explore un cas de maladie infantile shinkurana, dans lequel l’usage du masque sonore et les mécanismes de voix citées jouent un r le clef dans le processus d’attribution d’une agentivité aux entités pathogènes. L’article analyse ainsi le phénomène de l’imitation sonore comme une stratégie perceptive et cognitive efficace, massivement mobilisée dans un contexte d’apprentissage et de validation des représentations animistes. This article examines the role of sound imitation in the practice and representation of hunting and sickness among the Quechua of Amazonia (Pastaza, Peru). The analysis is based on a set of stories that presents an interaction with “masters of game” in an ordinary or ritual context. Beginning with a description of lure hunting techniques, the author shows the relevance of a communication mode based on sound simulation in controlled and uncontrolled interactions with entities protective of game (stories of hunting initiation or accounts of spirit encounters). After having demonstrated the consistency of this pattern in the sphere of hunting praxis, the author explores a case of infant sickness shinkurana, in which “sound mask” use and “quoted voice” mechanisms play a key role in the attribution of an “agency” to pathogenic entities. Thus the article analyses the phenomenon of sound imitation as an effective perceptive and cognitive strategy, heavily used in the context of learning and validating animistic representations.
Influência da naloxona e metisergida sobre o efeito analgésico do laser em baixa intensidade em modelo experimental de dor
Serra, André Peres e;Ashmawi, Hazem A;
Revista Brasileira de Anestesiologia , 2010, DOI: 10.1590/S0034-70942010000300008
Abstract: background and objectives: although the mechanism of action of laser phototherapy (lpt) is not known, it is a promising analgesic method. the aim of this study was to evaluate whether the action of lpt depends on the activation of peripheral opioid or serotonergic receptors. method: inflammatory pain was induced through the injection of carrageenin in the left posterior paw of male wistar rats. the ingaaip visible laser diode (660 nm) with fluency of 2.5 j.cm-2 was used. von frey filaments were used to analyze mechanical hyperalgesia. animals were separated into five groups: carrageenin; laser (lpt); non-coherent light; lpt + naloxone; and lpt + methysergide. results: low-level laser phototherapy proved to be an effective analgesic method, while non-coherent light did not show a similar effect. the use of naloxone blocked the analgesic effect of lpt, while methysergide did not affect lpt-induced analgesia. conclusions: according to the parameter used in this study, lpt produced analgesia. analgesia induced by laser phototherapy is mediated by peripheral opioid receptors. laser phototherapy does not seem to interact with peripheral serotonergic receptors.
Exploitation pétrolière et dynamique des territorialités indiennes dans la région du haut Pastaza péruvien

M@ppemonde , 2006,
Abstract: L’analyse de la restructuration de l’espace dans le haut Pastaza péruvien, région en marge devenue zone pétrolifère stratégique, permet de mettre en évidence deux logiques socio-culturelles qui s’affrontent: celle apparue avec l’activité pétrolière et celle découlant du mode de vie traditionnel. On s’intéresse dans ce contexte à la redéfinition des formes de pouvoir locales et à la reconfiguration des territorialités indiennes.

Abstract: objective: to describe socioeconomic inequalities regarding the use, expenditures and the income committed to the purchase of medicines. methods: a cross-sectional population-based study was carried out with 1,720 adults living in the urban area of florianópolis, southern brazil, in 2009. cluster sampling was adopted and census tracts were the primary sampling units. use of medicines and the expenditures incurred in their purchase in the past 30 days were investigated through interviews. use, expenditures and the income committed concerning medicines were analyzed according to per capita family income, self-reported skin color, age and sex, adjusting for the complex sample. results: the prevalence of medicine use was 76.5% (95%ci: 73.8; 79.3), higher among women and in older individuals. the mean expenditure on medicine was r$ 46.70, with higher values among women, whites, older individuals and among richer people. while 3.1% of the richest committed more than 15% of their income to purchasing medicine, that figure reached 9.6% in the poorest group. the proportion of people that had to buy medicines after an unsuccessful attempt to obtain them in the public health system was higher among the poor (11.0%), women (10.2%) and the elderly (11.1%). a large part of the adults bought medicines contained in the national list of essential medicines (19.9%) or in the municipal list of essential medicines (28.6%), with significant differences according to gender, age and income. conclusions: there is socioeconomic, age and gender inequality in the income committed to the purchase of medicines, with worse conditions for the poor, older individuals and women.
CCS Membrane Development at CIUDEN’s Technology Development Centre for CO2 Capture  [PDF]
Jose A. Gutierrez Bravo
Journal of Power and Energy Engineering (JPEE) , 2018, DOI: 10.4236/jpee.2018.612001
Abstract: CO2 concentration to the atmosphere has risen faster than ever in the last century. This is highly due to fossil fuel combustion which is the major anthropogenic CO2 source. Membrane technology is an important alternative for reliability, flexibility and economically competitiveness for Carbon Capture and Storage (CCS) processes. The use of membranes has applicability to CCS technologies mainly for CO2, O2 or H2 separation, although most of the membrane studies for CO2/O2 production have been carried out at laboratory scale and will require a step further for commercial scale. This paper will present current membranes R & D needs when applied to CCS systems and CIUDEN capabilities for membrane technological development and testing under real conditions. It covers from O2 separation membrane integration in the process, and applied to the oxy-combustion CO2 capture, to post-combustion technologies for membrane CO2 separation, tested under real conditions or H2 production catalytic-membranes through gasification. At CIUDEN CCS facility important membrane evaluations can be carried out for the module integration, testing of materials performance and behavior under real conditions.

Abstract: Pesticide degradation studies are essential to evaluate its impact in the environment and on non-target organisms. The effect of repeated soil applications of the herbicide glyphosate on its dissipation and on soil microorganisms was studied by radiometric and microbial techniques. Results indicated fast dissipation of the [14C]-glyphosate or [14C]metabolites extractable residues (half-life of 0.92±0.29 month), but increasing half-lives of total mineralization ranging from 2.2 to 3.4 months as the number of applications increased from 1 to 4. No significant correlation was found between 14CO2 production and dehydrogenase activity.
