The objective of this study consisted of evaluating the effect of the application of chitosan(Q),1-methylcyclopropene(1-MCP)under two controlled temperatures on some physical,physiological,and chemical parameters contributing to the quality of Persian lime Citrus latifolia *** treatments were evaluated,resulting from the combination of four senescence retardant applications(Q,1-MCP,1-MCP+Q,and without application)on fruits stored at two temperatures(12/20℃.Epidermis color(luminosity,chromaticity,and hue),fruit appearance,respiration,weight loss,total juice content,total soluble solids,and titratable acidity were registered during the *** results indicate that the 1-MCP and Q combination favored fruit postharvest quality conditions such as reducing respiration rate;maintaining fruit good appearance,turgidity,and brighter fruit chromaticity;fruits treated with chitosan and stored at 12℃,favored total soluble *** the other hand,Variables such as weight loss,juice content,acidity,phenols,flavonoids,antioxidant activity,and hue values were favored by a 12℃ storing temperature regardless of the *** general,the use of modified atmospheres,senescence retardants,and refrigeration as postharvest methods,can increase Persian lime shelf life.

A numerical analysis to the non-linear fin problem

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2008年第5期9卷 648-653页

作者： rafael CORTELL Department of Applied Physics Polytechnic University of Valencia 46022 Valencia Spain

In this paper a numerical analysis is carried out to obtain the temperature distribution within a single fin. It is assumed that the heat transfer coefficient depends on the temperature. The complete highly non-linear problem is solved numerically and the variations of both, dimensionless surface temperature and dimensionless surface temperature gradient as well as heat transfer characteristics with the governing non-dimensional parameters of the problem are graphed and tabulated.

Proteomics and the genetics of sperm chromatin condensation

引用

Asian Journal of Andrology 2011年第1期13卷 24-30页

作者： rafael Oliva Judit Castillo Human Genetics Research Group IDI BAPS Department of Ciencias Fisiologicas I Faculty of Medicine University of Barcelona Barcelona 08036 Spain Biochemistry and Molecular Genetics Service Hospital Clinic i Provincial Barcelona 08036 Spain

Spermatogenesis involves extremely marked cellular, genetic and chromatin changes resulting in the generation of the highly specialized sperm cell. Proteomics allows the identification of the proteins that compose the spermatogenic cells and the study of their function. The recent developments in mass spectrometry （MS） have markedly increased the throughput to identify and to study the sperm proteins. Catalogs of thousands of testis and spermatozoan proteins in human and different model species are becoming available, setting up the basis for subsequent research, diagnostic applications and possibly the future development of specific treatments. The present review intends to summarize the key genetic and chromatin changes at the different stages of spermatogenesis and in the mature sperm cell and to comment on the presently available proteomic studies.
