Abstract: Introduction: Gastrointestinal stromal tumor (GIST) occurrence is uncommon and usually manifested by nonspecific signs and symptoms, which hinders its reasoning as a diagnostic hypothesis. The objective is to report a case of female GIST with curative treatment through video-laparoscopy with partial gastrectomy. Case report: A 61-year-old female patient attended the Luiz Gioseffi Jannuzzi School Hospital (HELGJ) emergency room, with a sudden onset of upper gastrointestinal bleeding with hemodynamic instability. After stabilization, she was admitted for diagnostic investigation, showing sub-epithelial lesion of antrum in upper digestive endoscopy (UDE) and solid-cystic mass in the gastric antrum to computed tomography (CT). The conduct was the video laparoscopy surgical approach with partial gastrectomy. The histopathological and immunohistochemical aspects of the surgical specimen showed a gastrointestinal stromal tumor (GIST) in a gastric antrum of low grade of malignancy, positive e-Kit and mycotic index (50 cga) < 5. Discussion: Compared to the scarce reports in literature, the case described presented typical epidemiology, but the clinical picture was not the most incident. Conclusions: Given the rarity of this pathology cases, it is essential to report these in order to elucidate the specificities and also to discuss diagnostic and therapeutic methods.

Abstract: O objetivo do artigo é construir um modelo que possa avaliar os diversos fatores que contribuem para o risco percebido de mortalidade precoce de Micro e Pequenas Empresas (MPE). Os fatores foram extraídos de uma pesquisa elaborada por Filardi (2006), com cem MPE disponibilizadas pela Junta Comercial de S o Paulo (JUCESP), sobre quais fatores que contribuíram para a mortalidade prematura dessas empresas. Esse trabalho de caráter exploratório prop e a Metodologia Multicritério de Apoio à Decis o Construtivista (MCDAC) para identificar os riscos percebidos desses fatores. Como resultado o modelo pode auxiliar o empreendedor a se precaver da possibilidade de sua empresa aumentar as estatísticas de mortalidade precoce das MPE

Abstract: Os relacionamentos interorganizacionais têm sido tema de diversos estudos e hipóteses que d o conta da sua importancia para o sucesso das organiza es. Um modo de classificar a forma dos relacionamentos entre organiza es é a proposta por Uzzi (1997),que classifica os relacionamentos em imersos socialmente ou de mercado. Estes relacionamentos interorganizacionais afetam a vida das organiza es e s o de vital importancia para o entendimento do mercado em que as organiza es est o inseridas. Neste sentido, essa pesquisa teve como perguntas centrais: Qual o desempenho das organiza es socialmente imersas? Seu desempenho é maior por conta desse relacionamento? Existe rela o entre o desempenho e o tipo de relacionamento? Para atingir tal objetivo, propomos um modelo de medi o de desempenho das organiza es envolvidas baseado no MCDA-C, metodologia de apóio a decis o construtivista, aplicado a um conjunto de organiza es da constru o civil do Balneário A ores, localizado em Florianópolis, Santa Catarina. Esse grupo de organiza es foi escolhido por base estudo da imers o social, anterior a essa pesquisa, desenvolvido por Wehrle (2008). Como resultado, foi possível verificar que os relacionamentos imersos afetam o desempenho das organiza es, sendo benéficos para as organiza es apenas quando essas conseguem gerenciá-los. Portanto, ter muitos relacionamentos imersos pode prejudicar o desempenho das organiza es.

Abstract: The Data Envelopment Analysis (Data Envelopment Analysis - DEA) has been extensively used as management support, in estimating the relative performance of production units similar. Particularly has been applied to companies that work using multiple inputs to produce multiple products, for which it is difficult to assign prices or weights. The study is an exploratory, descriptive and evaluative. The techniques of data collection were observation, document analysis and literature review. The information collected is treated in a qualitative and quantitative. This paper presents a case study of applying this method to a nonprofit corporation, the area of professional education and technical and technological services (SENAI, the National Service of Industrial Learning). It studies the replacement of existing procedures for evaluating performance of production units, including operational aspects, financial and management. Assesses the performance of 21 operating units of SENAI two perspectives: financial and quality. The DEA model chosen is variable returns to scale -oriented product (CCB). The results show that 33.3% of the units are efficient in the financial perspective, 42.8% are from the perspective of quality, and 19, 0% of total units are effective from both perspectives. We conclude that the DEA model is appropriate for performance evaluation of the operational units of SENAI provides valuable results for the managers of the institution such as setting goals and identifying benchmarks for the inefficient units.

Abstract: it was studied the removal efficiency of nitrogen and phosphorus from effluent of a cashew nut industry by using an aerobic reactor operated in repetitive batch, inoculated with aspergillus niger an400. the reactor was fed with 5 l of wastewater, supplemented with glucose in the concentration of 1 g.l-1 (phase i) and 5 g.l-1 (phase ii ). each phase had six operational cycles, with total reaction time of seven days per cycle. the ph values of the effluents in phase i varied from 6.4 to 8.7 and in phase ii , it varied from 3.1 to 7.0. the reactor achieved good results of removal without nutrients accumulated in the medium, during phase ii : 49% to total phosphorus, 60% to orthophosphate, 79% to ammonia, 78% to nitrate, and 90% to nitrite, indicating that the lesser release of nutrients by microorganisms occurred in the presence of higher glucose concentration.
Towards a good notion of categories of logics
Caio de Andrade Mendes,Hugo Luiz Mariano
Mathematics , 2014,
Abstract: We consider (fi?nitary, propositional) logics through the original use of Category Theory: the study of the "sociology of mathematical objects", aligning us with a recent, and growing, trend of study logics through its relations with other logics (e.g. process of combinations of logics as ?bring [Gab] and possible translation semantics [Car]). So will be objects of study the classes of logics, i.e. categories whose objects are logical systems (i.e., a signature with a Tarskian consequence relation) and the morphisms are related to (some concept of) translations between these systems. The present work provides the fi?rst steps of a project of considering categories of logical systems satisfying simultaneously certain natural requirements: it seems that in the literature ([AFLM1], [AFLM2], [AFLM3], [BC], [BCC1], [BCC2], [CG], [FC]) this is achieved only partially.

Abstract: The Neotropical obligate fungivorous beetle Ceracis cucullatus (Mellié) has attracted attention of coleopterists due to the increasing number of records of populations in Africa. Although its disjunct populations have been interpreted as a cohesive taxonomic unity, previous comparisons between African and Neotropical specimens revealed differences in their external morphology, causing uncertainty about the true unity of the species. Here, we compare the external morphology of specimens named Cer. cucullatus from several localities of the Neotropical, Palearctic, Afrotropical, Afrotemperate and Oriental regions. As results, we reverse three previous junior synonymies of Cer. cucullatus, proposing Cer. lamellatus (Pic) and Cer. tabellifer (Mellié), both reinstated status and new combinations, as separate species. We also propose Enn. bilamellatum Pic as a new synonym of Cer. tabellifer. In face of these taxonomic changes, we identify Cer. tabellifer as the actual invasive species on African lands, instead of Cer. cucullatus as was previously accepted. Then, through historical records gathered from scientific collections and literature, and through examination of recently collected specimens from South Africa and Brazil, we provide data on host fungi and geographic distribution of Cer. tabellifer. Based on these data, we discuss possible explanations to the successful invasion of Cer. tabellifer in Africa and elsewhere and its potential threat to native faunas of ciids. This study helps to fulfil an old gap in the literature on biological invasions, with considerably more studies on predatory species, disease vectors or potential pests of agricultural crops, than on non-pest fungivorous organisms.
