Abstract: with the objective of studying the effects of the application of different sources and doses of calcium silicate on the sugar-cane culture, cultivar sp80-1816, one installed an experiment in a typic hapludox, in an area located at the jo?o mendes - "jm" distillery (sítio vó zirica), in the municipal district of perd?es, in the state of minas gerais. a random block experimental layout was used, with four repetitions and a 3x3+1 factorial outline, three being sources of calcium silicate (silifértil, extrativa e agronelli) and three being doses (150, 300 and 450 kg/ha), an additional treatment, without silicate (control), totalizing 10 treatments. the different sources and doses were applied in the planting furrow together with npk manuring. the application of calcium silicate in the planting furrow, independently of the sources and doses used, provided an increase in the fiber level percent/cane, but didn't influence the total yield recoverable sugar (atr) brix, pol e pureness (%) of cane plant.

Abstract: This study aimed to investigate the concept formation involved in the study of food chain by utilizing the vygotskian referential and playful activities. The teacher-researcher planned the activities that were experienced by a group of children in an elementary school aged 4 to 5. The topic chosen intended to support ecological literacy and the construction of scientific concepts in children. For the data collect, the study employed diverse instruments of a playful nature, such as theatre, games, drawings, and video-recorded interviews. The study showed a generally positive influence of playful activities to develop a perception of belonging to the food chain and becoming aware of the importance of caring for animals in order to preserve life, as well as an evolution inside the phases proposed by Vygotsky.

Abstract: The ESA Gaia mission, to be launched during 2013, will observe billions of objects, among which many galaxies, during its scanning of the sky. This will provide a large space-based dataset with unprecedented spatial resolution. Because of its natural Galactic and Astrometric priority, Gaia's observational strategy was optimized for point sources. Nonetheless, it is expected that 10^6 sources will be extragalactic, and a large portion of them will be angularly small galaxies. Although the mission was designed for point sources, a dedicated analysis of the raw data will allow the recovery of morphology of those objects at a 0.2" level. This may constitute a unique all-sky survey of such galaxies. We describe the conceptual design of the method we created for performing the morphological analysis of these objects as well as first results obtained from data simulations of low-resolution, highly binned, satellite data. Based on the obtained results we conclude that it is possible to push the limits of the Gaia space mission by analyzing galaxy morphology. (Abridged)

Abstract: In Brazil, the amount of pesticides consumed doubled in the last 10 years. Thus, in 2008 it assumed the lead position in the world. However, its indiscriminate application in agriculture without the use of the necessary care has contributed to environmental degradation and increased occupational exposures, making it a serious health problem in the country. The recent study looked to evaluate the auditory health and risk factors in rural workers exposed to pesticides in Piedade de Caratinga County—MG, and chart their socioeconomic profile and lifestyle while identifying the types of crops and the use and management of pesticides. Developed, then, a descriptive and exploratory study involving 23 men, rural workers, exposed to pesticides, with no history of exposure to noise, with changes in meatoscopy and aged ≤50 years of age. The results show the sample consisted of 23 men with a mean age of 36.7 ± 9.3, whom have low education, with a monthly income of 1 minimum wage, working in the fields for over 15 years. There was a predominance of horticulture using organophosphate pesticides and pyrethroids. Part of the sample shows auditory loss, the most common sensorineural conductive loss. It is essential that the population exposed to this type of risk is informed and receives guidance from educational campaigns developed by the multidisciplinary team of basic health units.

Abstract: association of birds to bamboo stands in southern brazilian atlantic forest, londrina, parana state, brazil. bamboo stands have been considered relatively important for a high number of bird species, specially in amazonia. in the present study variations on the abundance of bamboo associated birds were evaluated in areas with different availability of bamboo chusquea sp. present inside native forest in the southern portion of the atlantic forest, parana state. point counts were performed during 25 days in five transects, three in bamboo stands areas and two where this microhabitat was absent; the transects differ in the availability of bamboo. the study areas were the mata dos godoy state park and an adjacent forest fragment, which together sum a total area larger than 2,000 ha, in northern parana state, southern brazil. nineteen bird species were analyzed and only five of them were recorded in the transects where the bamboo was absent. five bird species decreased significantly their abundances according the decreasing in the availability of bamboo (g-test, p < 0.01). none species had higher abundance in the transects where the bamboo was absent. differently of amazonia, bamboo stands in the southern portion of the brazilian atlantic forest are not extensive areas; actually, this type of microhabitat is more disperse throughout the understory. even so, this microhabitat may be important for conservation of certain bird species in the atlantic forest.

Abstract: this study was conducted in the cotrigua?u district, situated on the bank of the juruena river, in mato grosso state. the collects were carried out from august 22 to 25, 2007 with chemical baits to attract male orchid bees. the bees were captured on a daily basis, from 8 a.m. to 12 p.m. of the 89 males captured three belonged to eufriesea pulchra smith. before the present study, e.pulchra had been reported in the states of pará, amazonas, amapá, (dubiously) s?o paulo, and maranh?o. this occurrence extends its geographical distribution range by 900 to 2,000 km southwards in south america, as it is now recorded in the amazon and platina basins.

Abstract: this study was conducted in the chapada dos guimar?es national park and in the província serrana of mato grosso state, from may 2003 to july 2005 and involved the use of chemical baits to attract male orchid bees. a total of 498 males were captured, of which 38 were eulaema (apeulaema) pseudocingulata oliveira. twenty-nine of these were collected in the national park and nine in the província serrana. e. pseudocingulata was reported as endemic to the amazon basin, however in the platina basin the species is sympatric to e. cingulata (fabricius), a sibling species of similar morphology and color pattern but with a broader geographic distribution.
