Visitando feiras de produtores locais na cidade de Nova Iorque por um ano, entre junho de 2008 e maio de 2009, verificou-se significativa amplitude varietal das maçãs, demonstrando-se um aspecto particular da diversidade vegetal. Evidenciadas no verão pela presença volumosa, é no outono e inverno que se nota a diversidade intraespecífica, atravessando todos os períodos sazonais. Verificou-se a existência de mais de quatro centenas de espécies vegetais disponíveis no mercado, escolhendo-se a maçã como um dos tipos mais evidentes para a análise da diversidade, uma vez que se oferecem em 65 cultivares nas feiras do estado ao qual emprestam o apelido. Representam um tipo de diversidade que extrapola ao conceito de especialização, usualmente atribuído à agricultura dos países desenvolvidos, uma vez que convivem com outras espécies nos espaços em que são cultivadas. O objetivo deste artigo é demonstrar a diversidade genética e de usos das maçãs que se expressa na atividade comercial exercida nas ruas e praças nova iorquinas.

A necessidade de se ter profissionais capacitados para pensar a questão urbana e propor soluções inovadoras é o ponto de partida para a criação do curso de Arquitetura e Urbanismo na Faculdade de Ciências e Tecnologia da Universidade Estadual Paulista “Júlio de Mesquita Filho”. Quando da sua criação, toda a estruturação foi baseada na infraestrutura já existente no campus para que posteriormente novas instalações, adequadas às especificidades do curso, fossem pleiteadas. Com apenas oito anos de funcionamento, alunos e professores enfrentam dificuldades no desenvolvimento das atividades em função da falta de infraestrutura adequada. Dessa forma, o presente trabalho é dedicado ao desenvolvimento de um projeto que atenda de forma satisfatória as demandas existentes no curso. A partir da elaboração de estudos de projetos análogos e de analises das necessidades do campus e suas necessidades obtém‐se as diretrizes que encaminham para a escolha da uma área apropriada para implantação nesta unidade universitária e pautam o desenvolvimento do projeto, que busca inserir‐se de forma adequada ao contexto préexistente

After the discovery of ionizing radiation, its applications in various fields of science began to take significant proportions. In the case of medicine, there are the application areas in radiotherapy, diagnostic radiology and nuclear medicine. It was then necessary to create the field of radiological protection to establish the conditions necessary for the safe use of such ionizing radiation. Apply knowledge obtained during the graduation stage and in the practice of radiological protection in the areas of nuclear medicine and diagnostic radiology. In the area of nuclear medicine, tests were made in the Geiger-Muller counters (GM) and the dose calibrator (curiometer), the monitoring tests of radiation, waste management, clean of the Therapeutic room and testing the quality control of gamma-chambers. In the area of radiology, were performed tests of quality control equipment for conventional X-ray equipment and x-ray fluoroscopy, all following the rules of the National Health Surveillance Agency (ANVISA), and reporting of tests. The routine developed in the fields of nuclear medicine in hospitals has proved very useful, since the quality control of GM counters contribute to the values of possible contamination are more reliable. The control of dose calibrator enables the patient not to receive different doses of the recommended amounts, which prevents the repetition of tests and unnecessary exposure to radiation. The management of waste following the rules and laws established and required for its management. Tests for quality control of gamma chambers help to evaluate its medical performance through image. In part of diagnostic radiology, tests for quality control are performed in order to verify that the equipment is acceptable for usage or if repairs are needed. The knowledge acquired at the internship consolidated the learning of graduation course

The roots' powder of timbo species collected in different regions of Amazonia that were tested in larvae groupings, didn't produce differential significative effects in two strains of Musca domestica. The two species with the greater number of plants used in the trial were Derris urucu and Derris nicou; the individuals from the species came from regions considered as "forestal refugies" during the Amazonian pleistocene. Among each species the plants varied since that inefficient to control, until plants lethals to the fies. This differential capacity for larvae control among plants of the same species, originated from different regions, suggests that both species had their populations isolated, during the quaternary epoch. In regions or "forestal refugies", where both species were represented, D. urucu was superior to D. nicou in the capacity to control larvae. While among plants from F region (Peruvian-East refuge) of the State of Acre, the two species had convergence in the values of damage to larvae groupings. Among the another species, Derris sp. (yellow timbo or watermelon timbo) didn't show differences in larvae control between samples from the two regions; while the species that was introduced in the Amazonia Denis elleptica showed damage in the larvae groupings similar to the most effective plants of D. nicou and D. urucu.

The rotenone contents analysis in clones of three timbó species permited the classification of these plants based on their efficiency to control Musca domestica larvae. The results showed significant correlations between the rotenone contents in the Derris urucu and D. nicou clones with the capacity to control the larvae. The plants with high rotenone contents were more effective. The rotenone contents, the effect of Derris species clones on the flics and the localization of the plants origin, showed that among the plants could have happened a populational isolation in the Amazonia during the pleistocene epoch. In Derris sp., that presented lower rotenone contents and was ineffective to control of the larvae, these differences were not observed.

Musca domestica larvae present two different digestive chymotryptic activities found in the posterior midgut (PMG): one major soluble activity in the lumen and another minor present in cell membrane fractions. Both soluble and membrane-bound chymotryptic activities have different half lives of thermal inactivation (46 degrees C) in the presence and absence of 10 mM Triton X-100, indicating that they are two different molecular species. Purified soluble chymotryptic activity has pH optimum 7.4 and a molecular mass of 28 kDa in SDS-PAGE. It does not cleave short substrates, such as Suc-F-MCA, preferring longer substrates, such as Suc-AAPF-MCA, with a primary specificity (kcat/Km) for Phe rather than Tyr and Leu residues. In-gel activity revealed a unique band against S-AAPF-MCA with the same migration as purified chymotrypsin. One chymotrypsinogen-like sequence (MdChy1) was sequenced, cloned and recombinantly expressed in Escherichia coli (DE3) Star. MdChy1 is expressed in the proximal posterior midgut (PMG1), as seen by RT-PCR. Expression analysis of other chymotrypsin genes revealed genes expressed at the anterior midgut (AMG) and PMG. Western blot of M. domestica midgut tissues using anti-MdChy1 antiserum showed a single band in samples from AMG and PMG, co-migrating with recombinant and purified enzymes. Immunogold labeling corresponding to Mdchy1 was found in small vesicles (thus indicating exocytosis) and in the lumen of AMG and PMG, corroborating the existence of two similar groups of chymotrypsins. Transcriptomes of M. domestica AMG and whole midgut prepared by pyrosequencing disclosed 41 unique sequences of chymotrypsin-like enzymes (19 probably functional), from which MdChy1 is highly expressed. Phylogenetic reconstruction of Drosophila melanogaster and M. domestica chymotrypsin-like sequences revealed that the chymotrypsin genes expanded before the evolutionary separation of Musca and Drosophila.
