Abstract: the objective of this research was to investigate the effect of different air drying temperatures upon the physical, chemical and biological quality of white oat grains, albasul cultivar. oat grains (avena sativa l.) were submitted to stationary drying at 25, 50, 75 and 100 oc until 13 % of moisture, in totally randomized arrangement. in the samples, volumetric weight, weight of 1000 grains, germination and vigor were determined. the oats grains were husked, grounded at granulometry inferior to 0.5 mm, and analyzed according to centesimal composition, residual activity lipase and peroxidase, color and content of a-glucans. increasing the temperature of drying air intensified the reduction of biological quality, expressed through germinative power and vigor, and also led to a decrease in weight of 1000 grains and volumetric weight. the drying conditions were not sufficient to deactivate lipase and peroxidase, although they reduced enzymatic activity. drying with air temperature above 75 oc showed significant decrease in the a-glucans.

Abstract: this work aimed to study the selectivity of the insecticides carbaryl, deltamethrin, methyl parathion, permethrin and trichlorfon in relation to ascia monuste orseis (godart) (lepidoptera: pieridae) and to their predators brachygastra lecheguana latreille and protonectarina sylveirae (saussure) (hymenoptera: vespidae). based on concentration-response curves and lethal concentrations for 90% of the population (lc90), the differential selectivity index (dsi90), relative toxicity index and relative tolerance index (reti90) were calculated. methyl parathion and trichlorfon were selective to b. lecheguana (dsi90 = 2.83 and 1.75) and p. sylveirae (dsi90 = 2.95 and 3.59) against a. monuste orseis. deltamethrin and permethrin were selective to p. sylveirae (dsi90 = 1.98 and 2.70) against a. monuste orseis, but weren't selective to b. lecheguana (dsi90 = 0.21 and 0.64). b. lecheguana was less tolerant to deltamethrin, permethrin and trichlorfon than p. sylveirae (reti90 = 9.36, 4.23 and 2.05), but the opposite was observed to carbaryl (reti90 = 0.14). these two predators showed similar tolerance to methyl parathion (reti90 = 1.04). concentration-response curves of carbaryl, permethrin and trichlorfon to both predators, deltamethrin to b. lecheguana, and methyl parathion to p. sylveirae, showed greater slopes than these curves to a. monuste orseis.

Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.58034
The deficiencies of mineral elements, change the development of plants in a broad sense, and therefore may alter the growth and fruit quality. The objective of this work was to evaluate the influence of macronutrient and boron deficiencies on morphological characteristics of Jupi pineapple fruits. The treatments complete, -N, -P, -K, -Ca, -Mg, -S and -B were applied as nutrient solutions in plastic pots with 14 kg of purified beach sand and one pineapple plant as the experimental unit. The trial was set up a randomized complete blocks design with six replicate. Nitrogen deficiency reduced fruit mass with and without crown, fruit length and diameter and peduncle diameter, increased TA, TSS and vitamin C, reduced TSS/TA, pH, pulp coloration and sensory acceptance of the fruits; phosphorus deficiency reduced fruit mass with and without crown, fruit and crown length, potassium deficiency reduced fruit mass with and without crown, length and diameter peduncle and calcium deficiency reduced peduncle diameter. Peel thickness was not affected by any deficiency. Nitrogen is the nutrient that most influenced the fruits quality of pineapple Jupi.

Abstract: even though amazonia displays magnificent environmental heritage and abundance of water resources, it is exactly in the brazilian northern region, contained in this remarkable biome, that the worst indices of access to sanitation services and respective public health indicators are found. a case study carried out in the town of s?o gabriel da cachoeira, located to the northwest in the state of amazonas, with nearly 18,000 inhabitants, a large portion of whom are indians, revealed a complexity of factors related to water supply and public health improvement for urban centers in amazonia. lack of proper policies, environmental peculiarities, logistic and financial difficulties, are added to socio-cultural matters, migratory processes, and unorganized urbanization associated with environmental impacts. in order to improve the public health delivery under such circumstances, an interdisciplinary approach that will allow for water resources management, basic sanitation implementation, and the promotion of the inhabitants' support become necessary.

Health (Health) , 2014, DOI: 10.4236/health.2014.67079
Abstract: A constant reproduction of environmental injustices and health iniquities has demanded the employment of participatory/dialectic approaches to research and to intervene in the reality making possible the involvement of social actors in healthy public policies. On this framework, the aim of this paper is to analyse scientific production with dialectic approaches associated with public policies in the context of social, environmental and health problems, considering territorial scales of intervention and the correspondence with some relevant strategies of health promotion. A systematic bibliographic review was applied on a wide pan-disciplinary scientific data base and 36 papers were analysed and classified by their territorial scales of approach. The amount of papers found and their spread through a variety of journals showed a modest, but increasing production which has been dispersed in terms of knowledge areas. Within the classification of territorial approaches, 14 papers were classified as local, 5 as expanded and 17 as a multi-level. Although the papers classified as local approaches were in a good structure of stakeholders’ participation, they are limited to dealing with the global driving forces that reproduce the environmental injustices. Regarding this limitation, the multilevel approaches were identified as more opportune to jointly deal with social, environmental and health problems by means of allowing interaction through multiple territorial scales, fomenting the strengthening of community action, creating supportive environments, and building healthy public policies.
