In many mammalian species, it is known that males and females differ in place learning ability. The performance by men and women is commonly reported to also differ, despite a large amount of variability and ambiguity in measuring spatial abilities. In the non-human literature, the gold standard for measuring place learning ability in mammals is the Morris(More)
A reverse staining procedure is described for the detection of proteins in acrylamide and agarose gels with and without SDS. Protein detection occurs a few minutes after electrophoresis. The sensitivity on acrylamide gels is higher than that of Coomassie blue staining either on acrylamide gels or on electrotransferred membranes. Sequencing of protein bands(More)

Differential Evolution is a stochastic and meta-heuristic technique that has been proved powerful for solving real-valued optimization problems in high-dimensional spaces. However, Differential Evolution does not guarantee to converge to the global optimum and it is easily to become trapped in a local optimum. In this paper, we aim to enhance Differential(More)
Six chloroform/methanol-soluble proteins from oat endosperm (Avena sativa) have been isolated and characterized by a purification procedure based on extraction with volatile solvents, followed by reversed-phase high performance liquid chromatography. Three of these proteins, with an assessed molecular weight of 25,000, 27,000 and 32,000 Da, respectively,(More)
Twenty bacterial strains were isolated from a sample of contaminated heating oil and screened for their ability to use petroleum and several common fuels as the sole source of carbon and energy. One of the isolates, named MM5, was able to grow on petroleum derivatives and brought about an emulsification of those compounds. Gas chromatography studies showed(More)
In recent years, one of the most disconcerting issues in bioethics, a field closely related to legal disciplines, is surrogate gestation or surrogacy. Very little is known about the medical nature of these novel therapeutic processes in legal study. Different dilemmas emerge in the fields of ethics, medicine and law. This paper analyses the normative(More)
This paper describes the isolation of microorganisms from polluted heating oil. The growth of one of them has been studied (Acinetobacter calcoaceticus MM5) in several linear and branched hydrocarbons as well as the effect of its growth on commercial diesel oil. Acinetobacter calcoaceticus MM5 is not capable of using glucose as its only source of carbon,(More)
