1. Efeito crioprotetor de lactose e glicose em cÃlulas fÃngicas imobilizadas em alginato de sÃdio como mÃtodo de preservaÃÃo de culturas. / Cryoprotectant effect of lactose and glucose yeast cells immobilized in calcium alginate as a method for preservation of cultures
Cryopreservation is the method of choice in many banks of microorganisms because it leads to a situation of metabolic dormancy and consequently cultures are stable for long periods. By reducing the temperature may however be formed of ice crystals which tend to cause cell damage to cell damage in turn can be avoided by vitrification process which takes place

2. Tumor banks: the cornerstone of basic research in urology
PURPOSE: Tumor banks have the primary responsibility for collecting, cataloging, storing and disseminating samples of tissues, cells and fluids, which are used by researchers to identify diagnostic molecular markers, prognostic indicators and therapeutic targets. The objective of this review was to describe a simple, reliable and reproducible protocol for ob

3. Oócitos equinos: maturação in vitro e vitrificação / Equine oocytes: in vitro maturation and vitrification
In vitro maturation rates are low for equine oocytes in comparison with other species, although several media have been tested without satisfactory results. Vitrification of oocytes allows preservation of genetic material of relevant mares, the creation of genetic banks and the use of reproductive biotechniques. The first articles had the objective of evalua

4. Avaliação da demanda, do consumo eletrico e do controle de temperatura para condicionamento de ambientes, usando sistemas de refrigeração com termoacumulação. / Evaluation of demand, electric consumption and control of temperature for environment conditioning, using refrigeration systems with thermal storage.
The commercial and financial building together represent a great parcel of the consumption of electric energy in the commercial sector, about 24,6 % of the total. The environment conditioning systems and commercial refrigeration in these types of building are responsible for a great consumption of electric energy and demand, being in the band of 35 % through

5. Modelagem numerica e experimental do processo de mudança de fase em placas paralelas / Numerical and experimental modeling of phae chenge process in parallel plates
No presente trabalho estuda-se o fenômeno de mudança de fase de um PCM em placas paralelas que compõe um banco de gelo. Parâmetros importantes como o espaçamento entre as placas, a temperatura da placa, a temperatura do fluido de trabalho e a vazão, são considerados numa faixa variável. Desenvolveu-se um modelo numérico para simular o processo de so

6. Numerical analysis of water melting and solidification in the interior of tubes
Latent energy storage systems find applications in many engineering fields, including industrial refrigeration plants, air conditioning installations, recovery of heat in industrial processes, etc. To tackle the design of such systems, it is necessary to have correlations to account for the heat transfer during the melting and solidification of the phase cha

7. Avaliação numerica e experimental do conceito de banco de gelo de placas paralelas
An experimental and numerical study is carried out to evaluate ice banks of parallel plates type. A simplified representative model is analysed, a computational code was developed and compared with experimental results. The finite difference method is used to solve the governing equations. For the mathematical model discretization, the method of fixed grid i
