Investiga-se a equação de Schrödinger unidimensional com uma classe de potenciais V(|x|) que se anulam no infinito e apresentam singularidade dominante na origem na forma α/|x|β(0 < β < 2). A hermiticidade dos operadores associados com quantidades físicas observáveis é usada para determinar as condições de contorno apropriadas. Dupla degenerescência e exclusão de soluções simétricas, consoante o valor de β, são discutidas. Soluções explícitas para o átomo de hidrogênio e o potencial de Kratzer são apresentadas.

This study compared the effect of the treatment protocol for correcting Class Il malocclusion using the Herbst appliance followed by full fixed Straigh-wire mechanics, in two populations, one Brazilian and one of North American origin As a untreated control sample the data from the University of Michigan Elementary and Secondary School Growth Study (UMGS) was used. Our sample was composed of 12 males and 12 females, with initial mean age of 12 years 7 months and final mean ages of 15 years and 3 months. The Michigan patients comprised 21 females and 7 males, with an initial mean age of 11 years and 9 months and final mean age of 14 years and 4 months. The control sample was paired in number, sex and age to the treated Michigan sample. ln both treated groups, lateral cephalometric radiographs were obtained before the Herbst appliance was cemented and at the end of the fixed appliance phase, The first comparison involved the Brazil group and the untreated controls, which demonstrated that the association of the Herbst appliance followed by fixed Straight-wire appliances provoked positive effects on the dentofacial complex, improving pre-existing maxillo-mandibular relationships, besides increasing dentoalveolar compensations which contributed to correct the malocclusion. The second comparison, involved the Brazl1ian and North-American patients treated with the same protocol. Although the pre-treatment comparison showed that the two groups were not similar in all aspects, they presented almost identical therapeutic modifications, which indicate that the effect of' treatment was very similar. These results point out that, in Class ll treatment, the combination of Herbst/Straight-wire mechanics produce consistent and systematic effects, correcting or minimizing possible skeletal imbalances

Our objective is to present the concept of «proletariancondition”, considered by us as the fundamental existential condition (and foundational) of modern finances, which involves men and women deprived of the means of production for their social life,in the situation of «social class» of the proletariat. The (quote, unquote)«class» of the proletariat is the social group of men and women, alienated from the social ownership/control of the means of life production, who are subsumed to a particular historical existential condition: the condition of proletarians.

The term “independent media art” expresses an artistic-scientific process performed in the Art- Science Communication interface presented as Final Paper in Visual Arts baccalaureate modality. The first part consists in gather, in artisticscientific research, an overview of the production of independent comics, mainly in Brazil, as well as some of the manifestations that were derived from it. The identification is made from bibliographical and iconographical survey, both printed and virtual materials. The second part discusses the production of a comic of my own - Imperfect Lives - published independently. This work is inserted in the line of research “Artistic Processes and Procedures” of the Department of Fine Arts of the Art Institute of UNESP and describes: Creative process, production, dissemination and influences. The third and final section brings together the work done by me during the four-year course, whose theme has some relation with comics. Experiments are in various media, using one or another characteristic intrinsic to them. The monography includes as an appendix a copy of each issue of the fanzine Imperfect Lives. The methodology used was Freinetiana Educational Cybernetics, developed in the research group “Art media and Videoclip”, whose leading advisor is the one from this Final Paper. The result and discussion of the artistic research and scientific monography were reported in the following versions: PDF File repository for dissemination in the virtual library of the Institute of Arts. Hardcover version for physical collection in the Library of the Institute of Arts. Paper version for the committee. Template version appropriate for submission to International Scientific Congress in the area of Arts

A caracterização e isolamento do gene com expressão específica em raiz de café (Coffea arabica) que codifica uma peroxidase (CaPOX) e suas respectivas regiões promotoras, permitiu realizar a caracterização da expressão desse gene em reposta a estresse biótico (infecção por nematóides) assim como a análise funcional do seu promotor. Promotores tecido-específicos responsáveis pela regulação de genes responsivos a estresses bióticos tornam-se fundamentais em programas biotecnológicos que visam o aumento da resistência e tolerância vegetal. Partindo desse princípio, realizou-se a quantificação da expressão relativa do gene CaPOX em raízes de café utilizando plantas de Coffea arabica de um cultivar susceptível (Mundo Novo) e de outro cultivar resistente (IAC 388-17-1) a nematóides, respectivamente. Em paralelo utilizou- se plantas transgênicas de tabaco (Nicotiana tabacum SR1) contendo a versão completa do promotor do gene CaPOX em fusão transcricional ao gene repórter uidA (que codifica a β-glucuronidase; GUS) . A partir disso, pode-se observar que o gene CaPOX tem sua expressão aumentada em resposta a infecção por nematóides, sendo que a indução observada ocorre nos tempos iniciais pós-inoculação. Da mesma maneira, o promotor do gene CaPOX é responsivo a infecção por nematóides, sendo ativado nos tempos iniciais pós-inoculação

The Kaposi-associated Herpesvirus (KSHV) also known as Human Herpesvirus 8 (HHV-8) is associated with the development of Kaposi’s sarcoma (KS) and others limphoprolipheratives diseases such as Primary Effusion Lymphoma (PEL) and Multicentric Castleman Disease (MCD). Even though the virus is considered lymphotropic, it is able to infect others cell types such as macrophages, dendritic cells, endothelial cells, monocytes and fibroblasts. After infection, KSHV be latent expressing essential viral genes to its maintenance in a infected cell. However, in some circumstances may occur the reactivation of lytic cycle producing new viral particles. K1 protein of KSHV interferes in the cellular signaling inducing proliferation and supporting cellular transformation. K1 is encoded by viral ORF-K1, which shows high variability between different genotypes of KSHV. So far, it is not clear whether different isoforms of K1 have specific immunobiological features. The KSHV latency is maintained under strict control by the immune system supported by an adequate antigen presentation involving Human Leucocyte Antigen (HLA) class I and II. Polymorphisms of HLA class I and II genes confer an enormous variability in molecules that recognize a large amount of antigens, but also can increase the susceptibility to autoimmune diseases. Therefore, the present study aims to genotype HLA class I (A and B) and class II (DR and DQ) from volunteers to identify haplotypes that can provide better response to K1 epitopes of different KSHV genotypes. First of all, 20 volunteers were selected to genotype HLA genes. In our results we observed prevalence of certain HLA class I haplotypes as HLAA1, HLA-A2, HLA-A24, HLA-A26, HLA-B8, HLA-B18 e HLA-B44. After the in silico analysis using BIMAS and SYFPEITHI databases, we observed high scores for epitopes from the B genotype of KSHV, indicating...(Complete abstract click electronic access below)
