As leucemias são neoplasias malignas que acometem as células do sangue e têm origem na medula óssea. São cânceres de grande incidência e de difícil tratamento, havendo, portanto, a uma constante procura por terapias
The mineral exploitation activities are of great importance and contribution to the Brazilian economy. The PRAD requirement and the relative care during the mine closure, according to the EIA / RIMA processes, are ensured in order to be returned with the quality and biodiversity, similar as what was previously found at the beginning of the project. Transposition of soil, seed bank, twings transposition, natural and artificial pollutants, nucleation and planting of plant seedlings. This research purses the species and didactic vegetables without use in the recovery of degraded areas in activities of exploitation of iron ore. A bibliographic review of scientific papers, doctoral theses and research on digital scientific sites and platforms was used using the key words: mining, revegetation, plant succession, mine closure and tree species in the last 10 years. The most frequent species of this species were: M. calodendron, L. pinaster and S. glabra, found in areas of initial environmental recovery, and Lychnophora pinaster, Symphyopappus brasiliensis, Baccharis serrulata, Chromolaena sp., Trichogonia sp. and Trixis vauthieri, intermediate rescue trees. For the recently published articles, the families Asteraceae, Podaceae and Orchidaceae are the ones that have the largest number of representatives in areas of recovery after mineral exploitation, due to the adaptability to exposed soil or low nutritional resources.The main resources of the same and the culture and the culture is in the field of grass-fat, pau-brasil and eucalipto culture keys in reestablishment of degraded areas. It is necessary the elaboration of a rich seed bank and an environmental species cataloging of the particles before the degradation activity, guaranteeing the success and the quick maintenance of the weed species.
<p>O trabalho surgiu da iniciativa de uma aluna do curso de Engenharia Ambiental da UEMG, campus João Monlevade, cuja experiência profissional técnica em contabilidade a motivou a buscar formas de promover o comprometimento das empresas com a prática de responsabilidade ambiental. O objetivo foi reduzir o acúmulo de papel reciclável no local de trabalho, doando-o à associação de catadores (Atlimarjom), uma vez que o município não possui coleta seletiva operacional. Para execução deste estudo, procederam-se 35 visitas em escritórios de contabilidade e empresas afins - acumuladores de papel branco - para explanação do projeto e convites para a participação nele. Após o aceite de 14 empresas/escritórios (40%), uma logística com dias e horários foi definida para a coleta do papel. Como resultado, obteve-se a redução no acúmulo de papel no ambiente de trabalho e o aumento significativo das doações de papel branco feitas para a Atlimarjom, retratando uma prática eficiente e replicável para outros setores.</p>
