(Universidade Federal de São Carlos, 2012-06-29)
The use of alternative and renewable fuels is vital to solve the problems derived from the dependence of fuels, and the vegetal biomass is the only renewable source available in large scale that can be converted in energy. ...
Efeitos epigenéticos sobre a diferenciação in vitro de mioblastos e a expressão dos genes CAST e CAPN1 em bovinos
(Universidade Federal de São Carlos, 2013-09-20)
Epigenetics can be defined as the study of heritable changes in phenotype without the occurrence of changes in nucleotide sequence. Epigenetic modifications occur by the chemical changes in DNA and their associated proteins, ...
Demografia e diversidade genética de onça-parda (Puma concolor) e jaguatirica (Leopardus pardalis) da Estação Ecológica de Caetetus SP e sua importância para a conservação desses felinos
(Universidade Federal de São Carlos, 2013-02-28)
The loss and fragmentation of habitat due to intensive human intervention are the main threats to natural populations. Species with low density and large home range, like felids, are the most threatened species by these ...
