Estimativa dos impactos das mudanças climáticas na distribuição das espécies montanas do gênero Brachycephalus (Amphibia: anura) através da modelagem de nicho ecológico

The genus Brachycephalus is endemic to the Atlantic rainforest and is distributed mainly in the southeastern and southern Brazil. Currently, it has 17 recognized species, most of them, associated with mountainous habitats along the Serra do Mar and Serra da Mantiqueira ridges. Here we use an ecological niche modelling approach based on climatic variables, to assess the potential niche of the mountainous species of this genus. The model generated was then projected to future scenarios considering the last IPCC report, in order to estimate the impacts of climate changes on these species distribution. Results show a decrease in the total suitable area for the mountainous Brachycephalus species, as well as tendencies already observed for other organisms, such as, pole and upward migrations. A southern area on Planalto de Paranapiacaba increases in suitability for these species. We suggest special efforts on new surveys and conservation on the northern part of their distribution, once this seems to be the region more affected by climate changes on the projected scenarios

Mapeamento do processo de originação de etanol em uma empresa do setor de distribuição de combustíveis

The market segment of fuel distribution composes an important role in the development of Brazil’s industry and economy. However, it is a sector with intense competitiveness, especially in relation to ethanol. The search for competitive advantage and greater strength to the business are, therefore, of high relevance in this context, in which the concepts of Business Process Management has become more visible. Process Mapping, one of these concepts, has proven “TO BE”a strategic tool for companies which believe in flattening the structure and in the potential benefits that the improvement of its processes can provide. Thus, this work aims to map the process of Ethanol Origination of a company engaged in the distribution of this and other fuel products, and other niche markets. It was understood and designed the macro-process aforementioned and identified failures in subprocess related to it. After applying the method to select priority problems, using risk assessment criteria, five subprocess were identified to receive special action, which consisted in seeking improvements with those involved in the process, in representing its current and ideal models and in defining each department’s responsibilities for the activities in the subprocess proposed form. Thus, it is expected to mitigate mainly two negative effects found in the business: employee’s work overload and company's financial exposure

Chitosan-collagen scaffolds can regulate the biological activities of adipose mesenchymal stem cells for tissue engineering

Scaffolds of chitosan and collagen can offer a biological niche for the growth of adipose derived stem cells (ADSC). The objective of this work was to characterize the physico-chemical properties of the scaffolds and the ADSC, as well as their interactions to direct influences of the scaffolds on the behavior of ADSC. The methodology included an enzymatic treatment of fat obtained by liposuction by collagenase, ASDC immunophenotyping, cell growth kinetics, biocompatibility studies of the scaffolds analyzed by the activity of alkaline phosphatase (AP), nitric oxide (NO) determination by the Griess-Saltzman reaction, and images of both optical and scanning electron microscopy of the matrices. The extent of the crosslinking of genipin and glutaraldehyde was evaluated by ninhydrin assays, solubility tests and degradation of the matrices. The results showed that the matrices are biocompatible, exhibit physical and chemical properties needed to house cells in vivo and are strong stimulators of signaling proteins (AP) and other molecules (NO) which are important in tissue healing. Therefore, the matrices provide a biological niche for ADSC adhesion, proliferation and cells activities.

Avaliação dos aspectos da dieta alimentar de Pimelodus maculatus em dois importantes tributários do reservatório de Jurumirim, Alto Rio Paranapanema-SP

The species Pimelodus maculatus is one of the most abundant fish in many artificial reservoirs. Shows feeding plasticity and exploits all trophic levels in aquatic ecosystems. This study aimed to analyze and compare aspects of the diet of P. maculatus in two important tributaries (Taquari and Veados rivers) in the upper Paranapanema River system, and also investigate possible differences in the condition factor using its feeding habit as reference. Samplings were carried out every three months during 2011 and 2012 in two tributaries of Jurumirim's dam. After biometric analysis, fish were dissected to remove the stomachs that were fixed in formaldehyde 10% and conserved in alcohol 70%. The stomach content was analyzed under stereomicroscope and the food items were identified until the least possible taxonomic level. The diet was characterized based on the Alimentary Index (IAi). Feeding strategy and aspects of species autoecology were evaluated by the relation between abundance of prey-specific (Pi) and occurrence frequency (Fo) of the prey, and also was calculated the niche width of Levin (B). The condition factor was also established and values obtained in samples of both rivers were compared, correlating them with diet of the species

A indústria de defesa brasileira: o setor de carros de combate e a engesa

This paper analyzes the small and medium armored combat vehicle industry, in order to understand its modus operandi. We investigate the former largest Brazilian producer of small and medium armored combat vehicles, Engesa, and concluded that its world success was a result both of its privileged perception to occupy a market niche and of the special relationship among its CEO and the Brazilian Army. A combination of negative factors conduced the firm to its bankruptcy, in the beginning of the 1990s, but we also identified a huge business potential, which could be either occupied by Engesa, if it had not disappeared, or by a follower in this market.

Análise dos troncos radiculares, abertura da raízes e projeções cervicais de esmalte de furcas de molares superiores e inferiores: Estudo in vitro

Periodontal treatment of teeth with furcation lesions often have unpredictable results due to several factors that may hinder therapy or influence the progress of periodontal disease. Of these, the length of the root trunk may contribute to the early injury of the furcations or even cause complications for the application of the treatment; the opening of the roots can guide the type of treatment to be instituted and cervical enamel projections may hinder the instrumentation of the region or even act as a retention plate niche. Thus, the purpose of this study was measured using a digital caliper, root logs database 400 molar both the 1st and the 2nd and both upper and lower as well as analyze using appropriate index type projection cervical enamel and through appropriate classification the opening of the roots in order to guide the diagnosis and treatment plan. We conclude that there is variation in measures of root trunk between the faces of the teeth examined and that greater cervical enamel projection (ECP) correlates with a decrease in the length of the root trunk in the sample evaluated as the first molars have higher occurrence of roots with a degree of opening larger than the second molars.
