Abstract: alfred russel wallace traveled through the amazon from 1848 to 1852. his perceptions of the region were informed by his systematized knowledge but also influenced by judgments of an ethical and aesthetic nature, as was common among naturalists. he saw the region's 'natives' as peaceful and friendly but likewise susceptible to the vices of civilization. nature afforded a privileged setting both for the activities of natural history and for aesthetic pleasures. these features helped keep the naturalist in the region, where he could thus engage in his scientific activities.

Abstract: the aim of this study was to compare the electromyographic (emg) activity of the femoris rectus, femoris biceps, tibialis anterior and soleus muscles in squatting, associating the trunk in erect position with two angles of knee flexion (40° and 60°) and the trunk at 45° flexion with three angles of knee flexion (40°, 60° and 90°). all associations were performed with and without additional load (10 kg). the sample was composed of 12 healthy individuals with mean age of 21.1 ± 2.5 years and weight of 62.8 ± 7.4 kg. the emg of the cited muscles was isometrically registered in 10 squatting positions. for statistical analysis, friedman two-way anova and the newman-keuls post-hoc test were used. the results showed co-activation between the femoris rectus and femoris biceps muscles with the trunk in flexion and at 40° of knee flexion and between the femoris rectus and soleus muscles in the other positions considered (p < 0.05). it was also possible to observe co-activation between tibialis anterior and femoris biceps muscles with knee at 40° and 60° of flexion, with the trunk erect and in flexion and between the tibialis anterior and soleus muscles in the other positions (p < 0.05). concerning isolated muscular activation, higher knee flexion in squatting was an important factor to greater muscles activation, except for the soleus. trunk position and the additional load of 10 kg have influenced in the muscular activation of the femoris rectus at 60° of knee flexion, in which the erect trunk provided more activation. the femoris biceps presented greater activation when the knee was in 40° of flexion and the trunk flexioned. the co-activation between the femoris rectus and biceps with the trunk in flexion, and between the femoris rectus and soleus in the other positions, lead to new possibilities of exercises in rehabilitation.
Adaptability, Entrepreneurship and Stakeholder Integration: Scenarios and Strategies for Environment and Vulnerability  [PDF]
Jerónimo De-Burgos-Jiménez, Diego A. Vazquez-Brust, José A. Plaza-úbeda
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.210160
Abstract: The “vicious circle” between poverty and environmental deterioration is a major challenge for those developmental approaches which look to improve the welfare of vulnerable communities. Environmental deterioration increases poverty while, at the same time, poverty causes further environmental deterioration as the business activities which communities depend upon for survival aggravate environmental deterioration by causing pollution and waste. It is therefore necessary that firms and communities collaborate in order to develop innovative solutions to break this vicious circle. This paper argues that such collaboration should be based on genuine stakeholders’ integration and entrepreneurship, proposes a holistic framework to guide business intervention strategies, and further explores collaboration scenarios between firms and communities.

Abstract: workers in sawmills are exposed to biomechanical risks due to the postures adopted during their activities. the purpose here was to assess postures adopted by these workers by using the rapid entire body assessment (reba), in order to detect and classify possible biomechanical risks. fifteen male workers from the production section of a sawmill in jo?o pessoa, pb (mean age 44±10.9 years old) were assessed as to the postures adopted at work. a semi-structured questionnaire collected demographic and environmental data as well as functions in the workplace. musculoskeletal symptoms were identified using corlett's body map. four postures were evaluated: anterior trunk flexion with weight lifting, deep crouching, anterior trunk flexion with lateral inclination and extended body to move a press. the reba method showed a very high risk level for the anterior trunk flexion; the other postures - deep crouching, anterior trunk flexion with lateral inclination, and extended body to move a press - were shown to bear a high risk level. accordingly, 73.3% of the workers complained of back pain or discomfort and 26.8% of pain in the shoulder area. considering the risk levels assessed, there is a need for ergonomic and preventive interventions in the workplace so that workers adopt postures that best suit their work activities with lesser risk to their health.

Abstract: the objective of this work was to evaluate the influence of stocking density on growth, feed conversion ratio and survival of juvenile common snook (centropomus undecimalis). fish were collected from the wild and trained to accept artificial diets. individuals (13±0.4 cm and 23±0.3 g) were stocked into nine 5-m3 circular fiberglass tanks at three different densities: 3, 6 and 9 fish/m3 during a period of 180 days. tanks were supplied with seawater and continuous aeration. total ammonia-nitrogen (0 to 0.5 mg/l), water temperature (23.3 to 30.6oc), salinity (17 to 34 g/l), ph (7.8 to 8.4) and dissolved oxygen concentration (4.8 to 6.9 mg/l) were similar in all tanks. feed conversion rate (1.88, 2.06 and 2.31) and survival (100%, 98.9% and 96.3%) were significantly improved for fish stocked at the lower densities (3 and 6/m3). there were significant differences in average weight (110, 87 and 80 g) and length (20, 18.5 and 18 cm) among treatments. fish stocked at the lowest density (3/m3) showed the highest growth rate, and there was no difference between the others. however, final biomass (332, 511 and 703 g/m3) was directly correlated with density. a low density influences positively growth, survival and feed conversion in common snook rearing.
Influência da densidade de estocagem no cultivo de juvenis de robalo-flecha mantidos em laboratório

Abstract: O objetivo deste trabalho foi analisar a influência da densidade de estocagem no crescimento, convers o alimentar e sobrevivência de juvenis de robalo-flecha (Centropomus undecimalis). Os peixes foram coletados em ambiente natural e treinados a aceitar dietas artificiais. Os indivíduos, com comprimento total de 13±0,4 cm e peso de 23±0,3 g foram estocados em tanques circulares de fibra de vidro de 5 m3, com água do mar e aera o contínua, nas densidades de 3, 6 e 9 peixes/m3, por 180 dias. Os valores de am nia total (0 a 0,5 mg/L), temperatura da água (23,3 a 30,6oC), salinidade (17 a 34 g/L), pH (7,8 a 8,4) e oxigênio dissolvido (4,8 a 6,9 mg/L) apresentaram padr o similar entre os tratamentos. A convers o alimentar (1,88, 2,06 e 2,31) e a sobrevivência (100%, 98,9% e 96,3%) foram significativamente melhores nos tratamentos com 3 e 6 peixes/m3. As médias finais de peso (110, 87 e 80 g) e comprimento total (20, 18,5 e 18 cm) apresentaram diferen a significativa. A maior taxa de crescimento foi observada com 3 peixes/m3; entre as demais n o houve diferen a. Entretanto, a biomassa final (332, 511 e 703 g/m3) foi diretamente proporcional à densidade. A baixa densidade favorece o cultivo do robalo em rela o ao crescimento, sobrevivência e convers o alimentar.
