X1X1X2X2/X1X2Y sex chromosome systems in the Neotropical Gymnotiformes electric fish of the genus Brachyhypopomus

Several types of sex chromosome systems have been recorded among Gymnotiformes, including male and female heterogamety, simple and multiple sex chromosomes, and different mechanisms of origin and evolution. The ₁X₁X₂X₂/X₁X₂Y systems identified in three species of this order are considered homoplasic for the group. In the genus Brachyhypopomus, only B. gauderio presented this type of system. Herein we describe the karyotypes of Brachyhypopomus pinnicaudatus and B. n. sp. FLAV, which have an X₁X₁X₂X₂/X₁X₂Y sex chromosome system that evolved via fusion between an autosome and the Y chromosome. The morphology of the chromosomes and the meiotic pairing suggest that the sex chromosomes of B. gauderio and B. pinnicaudatus have a common origin, whereas in B. n. sp. FLAV the sex chromosome system evolved independently. However, we cannot discard the possibility of common origin followed by distinct processes of differentiation. The identification of two new karyotypes with an X₁X₁X₂X₂/X₁X₂Y sex chromosome system in Gymnotiformes makes it the most common among the karyotyped species of the group. Comparisons of these karyotypes and the evolutionary history of the taxa indicate independent origins for their sex chromosomes systems. The recurrent emergence of the X₁X₁X₂X₂/X₁X₂Y system may represent sex chromosomes turnover events in Gymnotiformes.

Reestruturação e centralidade em cidades médias. Considerações a partir de Londrina, Marília, Mossoró e São José do Rio Preto

Este trabalho trata das cidades médias, em particular das cidades de Marília, São José do Rio Preto, Londrina e Mossoró. Dentro desse estudo, o enfoque se dá para a compreensão e análise sobre o modo como estão combinados os espaços não edificados e os vazios urbanos, os espaços construídos e as vias de circulação e suas transformações ao longo do tempo. A proposta é analisar o processo de expansão do tecido urbano dessas cidades para compreender sua morfologia, bem como procurar fazer uma reconstituição, tomandose a dimensão espacial e temporal, com o intuito de que esta contribua na conferência das identidades próprias de cada cidade, viabilizando a identificação das semelhanças entre elas, como também de suas especificidades. Durante o desenvolvimento do trabalho procuramos identificar elementos promotores da reestruturação urbana pela qual as cidades têm passado nas ultimas décadas, tentando relaciona-los com as novas formas de produção e organização espaciais...

Moradia Estudantil da UNESP - Campus de São José do Rio Preto

O presente trabalho apresenta uma proposta de ampliação da moradia estudantil da UNESP do campus de São José do Rio Preto, o IBILCE - Instituto de Biociências, Letras e Ciências Exatas. Para tanto, foram realizados levantamentos acerca da questão habitacional para os estudantes no país, da realidade dos sistemas de assistência aos estudantes universitários nas escolas de nível superior, em principal do IBILCE, e também levantamentos de outras moradias estudantis, nacionais e internacionais, buscando referências. Deste modo, o projeto visa atender as necessidades específicas dos usuários em questão apresentando unidades habitacionais que proporcionem maior conforto além de contemplar áreas para convívio, lazer e prática de esportes. Pretende-se com esse projeto propiciar novas vagas para o campus de São José do Rio Preto, beneficiando mais universitários com uma habitação que promova condições adequadas para o estudo e uma infra-estrutura que contemple tanto áreas coletivas que beneficiem a socialização e o convívio entre os moradores como também locais com privacidade para o descanso e estudo deles

Fatores facilitadores e restritivos no processo de gestão de franquias sob o ponto de vista do franqueado: um estudo multicasos no setor de alimentação

The present study sought to identify which are the facilitators and restrictive in the creation and management of franchises from the point of view of process factors franchisees. For this, we first proposed to critically analyze its creation and management.The specific objectives of this work are: a) to understand in the light of the theory , the basic requirements for creating franchises b ) identify, from the literature review , facilitators and restrictive factors in the process of franchise management , c) develop a survey tool to critically analyze the processes of creating and managing a franchise from the point of view of the franchisee , and d ) to review the process of creating and managing franchises , from the perspective of four franchised food services in the municipalities of Ribeirão Preto and Sao Jose do Rio Preto - SP . A descriptive qualitative work, which found the most important features about the franchises, through a study of 4 franchises in the food industry of São Paulo was performed. To complete the survey was conducted a semi-structured interview, containing questions regarding the main elements of a business: creating, planning, organization, direction and control. It was found that franchising is a business model with controversies. There are people who deal well with the system and that through him realize dreams such as owning their own business. Others need to think many times before embarking in business since the entrepreneurship factor can be so intense that it hinders the acceptance of norms and duties to the system. This causes some factors such as communication, measurement of outcomes, implementation plan and among others are considered restrictive or facilitators in the process of strategy management of franchises

Perfil de ácidos graxos em batatas Chips comercializadas em são José do Rio Preto - Brasil

The objective this study was to evaluate the fatty acids profile of samples of chips potato marketed in the city of São Jose do Rio Preto-SP. We collected samples of 10 brands of chips potato, obtained from 3 different batches. The fatty acids profile was obtained by gas chromatography, with peak identified by retention times with standards of methyl esters and the results calculated and expressed as g/100g of the sample. The fatty acids profile in chips potatoes from different brands were on average 39.22% for saturated fatty acids, 39.64% for monounsaturated, 18.60% for polyunsaturated and 2.43% for trans fatty acids.

Aumento de produtividade em uma célula produtiva com processo de usinagem utilizando conceitos Lean

In the current competitive and global scenario, companies in search for solutions that become the production every time more efficient is increasing and at the same time cost reductions and cost eliminations are becoming increasingly evident and needed. In an attempt to improve production, this work aims to compare benefits obtained using principles of philosophy Lean Manufacturing in an productivity growth of a cell from an auto parts sector industry. For that purpose it will be studied the history, the concepts and the tools of philosophy Lean Manufacturing, thus using the as a business-strategic tool to accomplish goals that the company expects to get greater competitiveness and quality. The efficiency of philosophy Lean Manufacturing was already confirmed through applying the concepts in the process which has been improved inside an auto parts sector industry. At last, comparative analyzes showed benefits obtained with the use of Lean Manufacture tool called VSM, Value Stream Map, which translates the Value Stream Map of a particular family of parts as the identification, minimization and elimination of waste identified

Análise da suscetibilidade a corridas de massa aplicada a dutovias: estudo de caso na bacia do Ribeirão do Roque

This scientific research aimed at to analyse the susceptibility to debris flow of the watershed of Ribeirão do Roque (SP), focusing on the upstream areas of OSBRA pipeline. This is because, mass flow can cause damage to pipes, mainly due to conditioning hydro erosion of the land in the drainage crossings, including the undermining the banks of streams. Firstly, It was conducted a literature review, aiming to identify and understand the principal characteristics and conditions of debris flow. Secondly, the physical and anthropic factors and their respective weights of influence were selected and used to determine the mass flow susceptibility. It was selected the following physical factors: type and thickness of rocks, soil and unconsolidated materials; textural density; amplitude relief; relief slope; shaped valley; and shape of slopes. Such factors are present in the physiographic subdivision map of the study area. In addition, the anthropic attributes correspond to the classes contained in the land use map. Therefore, the physical and anthropic factors were integrated through the multi-criteria analysis in a GIS environment, generating a total susceptibility map of debris flow on the scale 1:50,000. The results showed that a significative part of the study area was classified as average susceptibility. However, it was identified areas with high susceptibility in the region in which the pipe cross the Ribeirão do Roque. Moreover, at which point the river presents a closed valley and a meander shape, without a fluvial plain that would be useful to attenuate the development of the process. Consequently, if a mass flow begins in any of these most susceptible regions located upstream of the pipe, the chances that the process develops by the river and causes the excavations of his bed are quite large. However, the pipelines cross these critical areas directly on the rock (diabase), which provides additional protection against possible ...
