Geochemistry of the Guaxupe Granulites, Minas Gerais, Brazil

Geochemical data for granulite terrain are presented from the northernmost portion of the Guaxupe Massif, at Mantiqueira Province, SE Brazil. Several types of granulites are recognized in the area: basic, intermediate and acid granulite. Major and trace elements (including REE) point to only one ma,oma source for these granulites generated at different times. Geochemical data point to plagioclase and apatite fractionation as responsable in the REE behaviour in intermediate and more basic rocks. Overall composition of the Guaxupe Granulites is similar to average composition of the lower crust.

Diamondiferous deposits in the Jequitai area (Minas Gerais, Brazil): a consequence of neotectonic processes

Diamonds obtained from small scale mining near Jequitai and surrounding villages are extracted from Tertiary conglomerates and Quaternary gravels of the Rio Jequitai. Eocretaceous conglomerates, which are locally poorly diamondiferous, cover parts of the Serra da Agua Fria and Serra do Cabral. They are of no economic importance. Analyses of neotectonic, post-Miocene features support a transpressive regime that gave rise to N-S to N25° E transcurrent faults, and WNW normal faults. The main evidence for neotectonic processes are inclined Tertiary sediments, drainage captures, striated laterites of Miocene age, and tilting of blocks that form the Rio Jequitai graben. Diamonds in the Tertiary terraces derived from the Eocretaceous conglomerates, which were affected by neotectonic processes, followed by erosion and concentration during redeposition of sediments.

Oferta e distribuição de estágio supervisionado em cursos de odontologia do estado de Minas Gerais, Brasil

Since 2002, which are in effect the Curriculum Guidelines for National Graduate courses in dentistry. The adequacy of the education needs of the Unified Health System is one of its main goals. As guidance, a way of achieving this goal is through supervised, which are presented as a tool for improving the academic scientific and technical, providing you know the reality of health and society in which to work. This study aims to examine the supply and distribution of supervised in graduate programs in dentistry in the state of Minas Gerais - Brazil. The material for analysis was obtained by sending letters to courses and consulting to its sites on the Internet. Were part of the study, 15 of the 23 courses in the state. It appeared that the load-hours of supervised showed variations between 315 and 975 hours, with only 20% of courses devoted 20% of the total working hours of supervised practice. There was no correlation between the total working hours of the course and working hours of supervised practice. The courses in which the supervised activities were represented only by extra muros showed a lower percentage of working hours in relation to total working hours of the course.

Ocorrência de enteroparasitos em centros de educação infantil no Município de Patos de Minas, MG, Brasil

Considering the high prevalence of the parasitic diseases in Brazil and its close relationship with the socio-economic and cultural levels of the population, aimed to establish the occurrence of enteroparasites in children of six Centers of Education Child (CEIs) of the municipality of Patos of Minas (MG). Were collected three samples of faeces of 161 children from zero to six years of age. Were used the Lutz and Baermann-Moraes' methods, to the detection of cysts of protozoa, eggs and larvae of helminths. Coproparasitological analyses showed positivity of 73%. The most frequent helminths were: Ascaris lumbricoides (50%), hookworm (22%) and Enterobius vermicularis (0.6%). Among the protozoa highlighted were: Entamoeba histolytica/E. dispar (22%) and Giardia lamblia (32%). The high occurrence of enteroparasites evidenced the need for an effective health policy in the CEIs of the municipality of Patos of Minas to the fight against intestinal parasites.

Fenologia de Caryocar brasiliense Camb. (Caryocaraceae) no Alto Rio Grande, sul de Minas Gerais

Phenological studies are important to understand the dynamics in forest ecosystems and also to enable adequate management of their native species. In the Cerrado regions of the high Rio Grande river (south of Minas Gerais State), Caryocar brasiliense species is found in highly distinct morphological forms with variable phenology. The aim of this study was to investigate phenological patterns within and between populations of both the tree and shrub forms of the individuals and to determine any correlation with abiotic factors. Thirty-five observations of the phenophases of the vegetative and reproductive stages were recorded ever), two weeks for 18 months. The activity index was analyzed for each stage and further analyzed to see if there were associations with the climate data by using Spearman linear correlation. The species was deciduous but leaf growth became retarded during the dry season, at which point leaf flushing stopped and total leaf fall occurred throughout the rainy season. The flowering and the fruit production occurred in the rainy season. The reproductive phase can be either annual or sub-annual. The activity index showed high synchronism within populations during the first flowering in all populations studied (> 80%). Flowering and mature fruits were highly synchronized according to Spearman correlations. Tree and shrub individuals of C. brasiliense had very similar times for their phenophases. The best period for collecting mature fruits in these regions is between February and March.
