Sistema fotovoltaico monocristalino para bombeamento de água

Since ancient times, it has been a huge challenge to all people around the world to manage to get their fresh water, keeping it clean and providing it to every human being, so that it can be used for their daily needs. This is especially true for small properties in the countryside and in isolated areas with low demographic density. Pumping the water in those regions is a solution that rationalizes its use in domestic chores, in animal rearing and in the irrigation systems of cultivated areas. Making feasible local, renewable and non-polluted energetic alternatives is the aim for those areas that are usually far away from the public electric network. Using photovoltaic solar energy is the alternative now proposed. For this objective was built a system with two monocrystalline panels, one pump, two water tanks, two level sensors and a solenoid valve to pump water, using a pump powered an array of monocrystalline solar panels. The main goal was to compare their rate of water flow and their energy consumption. The use of one data acquisition equipment allowed collecting meteorological, electrical and hydraulic values, and also serving for the control and activation of the pumping system. During four months in a row as from April 2009, arrangements with one or two panels were tested. Mathematics correlations and adjustment lines were used to interpret the behavior of obtained dataset. During the analyzed period the system followed the linear equations with great accuracy. The daily average amount of water pumped by the several tested arrays stayed between 1,100 and 2,500 liters, and that is enough to supply a small rural property. The pumping system with two panels effectively showed the major amount of water, but a system with one panel can be an economical solution until 1,500 liters on day. It did not characterize a direct relationship between power or quantity of photovoltaic panels and daily outflow of water pumping.

Interação entre irmãos em situação de cuidados formais

Este trabalho teve como objetivo descrever as principais características de famílias onde os filhos mais velhos são responsabilizados pela execução das tarefas domésticas e pelo cuidado aos irmãos menores, durante a ausência dos pais. Participaram deste estudo vinte famílias residentes à Vila Paranoá, Distrito Federal, com filhos de um a dezesseis anos de idade. Os dados foram colhidos através de entrevistas e sessões de observação sistemática do comportamento em ambiente natural, realizadas durante o período de almoço. A análise se deteve na organização familiar, desempenho em tarefas domésticas e interação entre irmãos, tendo sido possível classificar as famílias em três grupos qualitativamente distintos. Os resultados são discutidos em termos da necessidade de se considerar fatores de ordem social na análise do grupo familiar.

Morfologia e topografia do fígado e pâncreas de emas Rhea americana

As emas são aves ratitas nativas do continente sul americano, são consideradas aves primitivas do ponto de vista filogenético que constituem um grupo altamente especializado. Este estudo buscou caracterizar macro e microscopicamente o fígado e pâncreas de emas. O material foi coletado no Centro de Multiplicação de Animais Silvestres (CEMAS), na cidade de Mossoró-RN, Brasil, (Registro IBAMA n° 14.78912). Utilizaram-se 20 animais jovens com idade entre dois e seis meses independente do sexo. Em emas, o fígado se relacionava cranialmente com o ápice do coração, dorsalmente com os pulmões, esôfago e o proventrículo gástrico, caudalmente, com o ventrículo gástrico, o baço, o duodeno e parte do jejuno. Apresentava coloração vermelha escura e possuía apenas dois lobos, sendo o direito ligeiramente menor que o esquerdo. Histologicamente, era revestido por uma cápsula de tecido conjuntivo delgada e cada lóbulo hepático pôde ser identificado pela presença evidente de veias centrais, com muitos sinusoides comunicando-se com elas. O pâncreas, ventralmente, apresentava-se como uma fita fina, formado por um lobo dorsal e um lobo ventral. Longitudinalmente o pâncreas em emas localiza-se no mesentério dorsal desde o fígado até a flexura cranial do duodeno, mantendo-se preso às alças duodenais por ligamentos. Histologicamente, era composto por uma cápsula delgada de tecido conjuntivo denso, com discretos lóbulos separados por tecido conjuntivo capsular, compostos por estruturas tubuloalveolares e ductos. O fígado e pâncreas de emas apresentam padrão morfológico similar ao descrito para aves domésticas.

Acute heat stress impairs performance parameters and induces mild intestinal enteritis in broiler chickens: Role of acute hypothalamic-pituitary-adrenal axis activation

Studies on the environmental consequences of stress are relevant for economic and animal welfare reasons. We recently reported that long-term heat stressors (31 +/- 1 degrees C and 36 +/- 1 degrees C for 10 h/d) applied to broiler chickens (Gallus gallus domesticus) from d 35 to 42 of life increased serum corticosterone concentrations, decreased performance variables and the macrophage oxidative burst, and produced mild, multifocal acute enteritis. Being cognizant of the relevance of acute heat stress on tropical and subtropical poultry production, we designed the current experiment to analyze, from a neuroimmune perspective, the effects of an acute heat stress (31 +/- 1 degrees C for 10 h on d 35 of life) on serum corticosterone, performance variables, intestinal histology, and peritoneal macrophage activity in chickens. We demonstrated that the acute heat stress increased serum corticosterone concentrations and mortality and decreased food intake, BW gain, and feed conversion (P < 0.05). We did not find changes in the relative weights of the spleen, thymus, and bursa of Fabricius (P > 0.05). Increases in the basal and the Staphylococcus aureus-induced macrophage oxidative bursts and a decrease in the percentage of macrophages performing phagocytosis were also observed. Finally, mild, multifocal acute enteritis, characterized by the increased presence of lymphocytes and plasmocytes within the lamina propria of the jejunum, was also observed. We found that the stress-induced hypothalamic-pituitary-adrenal axis activation was responsible for the negative effects observed on chicken performance and immune function as well as for the changes in the intestinal mucosa. The data presented here corroborate with those presented in other studies in the field of neuroimmunomodulation and open new avenues for the improvement of broiler chicken welfare and production performance.

HEALTH PROBLEMS AWARENESS DURING TRAVEL AMONG FACULTY MEMBERS OF A LARGE UNIVERSITY IN LATIN AMERICA. PRELIMINARY REPORT

Health safety during trips is based on previous counseling, vaccination and prevention of infections, previous diseases or specific problems related to the destination. Our aim was to assess two aspects, incidence of health problems related to travel and the traveler’s awareness of health safety. To this end we phone-interviewed faculty members of a large public University, randomly selected from humanities, engineering and health schools. Out of 520 attempts, we were able to contact 67 (12.9%) and 46 (68.6%) agreed to participate in the study. There was a large male proportion (37/44, 84.1%), mature adults mostly in their forties and fifties (32/44, 72.7%), all of them with higher education, as you would expect of faculty members. Most described themselves as being sedentary or as taking occasional exercise, with only 15.9% (7/44) taking regular exercise. Preexisting diseases were reported by 15 travelers. Most trips lasted usually one week or less. Duration of the travel was related to the destination, with (12h) or longer trips being taken by 68.2% (30/44) of travelers, and the others taking shorter (3h) domestic trips. Most travelling was made by air (41/44) and only 31.8% (14/44) of the trips were motivated by leisure. Field research trips were not reported. Specific health counseling previous to travel was reported only by two (4.5%). Twenty seven of them (61.4%) reported updated immunization, but 11/30 reported unchecked immunizations. 30% (9/30) reported travel without any health insurance coverage. As a whole group, 6 (13.6%) travelers reported at least one health problem attributed to the trip. All of them were males travelling abroad. Five presented respiratory infections, such as influenza and common cold, one neurological, one orthopedic, one social and one hypertension. There were no gender differences regarding age groups, destination, type of transport, previous health counseling, leisure travel motivation or pre-existing diseases. Interestingly, the two cases of previous health counseling were made by domestic travelers. Our data clearly shows that despite a significant number of travel related health problems, these highly educated faculty members, had a low awareness of those risks, and a significant number of travels are made without prior counseling or health insurance. A counseling program conducted by a tourism and health professional must be implemented for faculty members in order to increase the awareness of travel related health problems.

Influence of the combined disposal of sewage and brine on meiofauna

[EN] Confluence of anthropogenic influences is common in coastal areas (e.g., disposal of different pollutants like industrial and domestic sewage, brine, etc.). In this study we assessed whether the combined disposal of domestic sewage and brine altered patterns in the abundance and assemblage structure of subtidal meiofauna inhabiting sandy seabeds. Samples were collected in May 2008 and January 2009 at varying distances (0, 15, and 30 m) from the discharge point. Meiofaunal abundances were consistently larger at 0 m (1663.05 ± 1076.86 ind 10 cm?2, mean ± standard error) than at 15 m (471.21 ± 307.97 ind 10 cm?2) and 30 m (316.50 ± 256.85 ind 10 cm?2) from the discharge outfall. This pattern was particularly accentuated for nematodes. Proximity to the discharge point also altered patterns in meiofaunal assemblage structure, though temporal shifts in the sedimentary composition also contributed to explain differences in the meiofaunal assemblage structure. As a result, meiofauna may be a reliable tool for monitoring studies of the combined disposal of sewage and brine as long as potential confounding factors (here temporal changes in grain size composition) are considered.

El proyecto ético-político del Trabajo Social en Misiones visibilizado a través de las prácticas profesionales del Trabajo Social, egresados en el periodo 2003-2010. 16H323

Consideramos que la actuación profesional de las/os Trabajadoras/es Sociales debe ser entendida como una construcción de sentidos y significaciones, porque dan cuenta de la presencia de distintas dimensiones (epistemológica, teórica, metodológica y operativa),un posicionamiento ideológico que atraviesa y configura el hacer y, que permite transitar el camino de reconocimiento, interpretación y direccionalidad de la acción. Cuando hacemos referencias al quehacer, involucramos como parte intrínseca del proceso, la puesta en acto de un posicionamiento ideológico en el que se conjugan valores y principios que sustentan esta acción y, a este sentido de la acción, denominamos el “Proyecto Ético Político”. Las prácticas profesionales deben ser analizadas sociohistóricamente dado que las mismas están atravesadas por diferentes dimensiones: históricas, sociales, políticas, económicas, institucionales, etc. pero no podemos considerar como determinantes en la producción de los servicios sociales institucionales; por ello, nos ocupa y preocupa, reconocer en el hacer cotidiano cómo se materializa el Proyecto Ético Político del profesional del Trabajo Social, materializándose así el objetivo central de la investigación: “Reconstruir las prácticas profesionales de los Trabajadores Sociales en la Provincia de Misiones, egresados en el periodo 2003-2010, en el marco del proyecto ético

Empleadoras del servicio doméstico en la Ciudad de Buenos Aires. En: Avá, nº 15

La cotidianeidad del trabajo doméstico remunerado que realizan las mujeres de sectores populares en los hogares de sus empleadores de sectores medios supone un entrelazamiento de niveles. Centrándonos en los relatos de experiencias de las empleadoras daremos cuenta de la manera en que la relación entre ambas se ve atravesada por relaciones afectivas no contractuales, en donde la reciprocidad, el antagonismo y la complicidad tornan aún más complejo el vínculo en cuestión. Con este telón de fondo, analizaremos el modo en que se producen y practican las relaciones de clase en el intercambio afectivo que se genera entre ambas. Al analizar ejemplos obtenidos de un trabajo etnográfico realizado en la Ciudad de Buenos Aires daremos cuenta de las formas de percepción, categorización y argumentación que utilizan las empleadoras como instrumentos desde donde comprender los mecanismos de naturalización, cuestionamiento y/o legitimación de la desigualdad.

Antropologia y desarrollo: Formas de coordinación e institucionalizacion de la economia en el sector agrario (Misiones, Argentina) 16H256

El proyecto se orientó a la aplicación de las contribuciones de la antropología y la sociología económicas para la comprensión de problemas vinculados al desarrollo rural. El análisis se centró en las formas de incorporación de los pequeños productores al mercado y a las actividades económicas. Los resultados de la investigación muestran el carácter limitado del mercado para dar cuenta de las formas de coordinación económica y la necesaria pluralización del espacio, marcada por la coexistencia de lógicas domésticas, mercantiles, industriales y cívicas.
