Produção de etanol a partir de torta de mamona (Ricinus communis L.) e avaliação da letalidade da torta hidrolisada para camundongos

The castor bean cake is rich in starch (48 ± 0.53%) and bears a problem linked to the occurrence of a toxic protein (ricin). The chemical hydrolysis (ratio solid:liquid = 1:6; H2SO4= 0.1 mol L-1; 120 °C; 40 min) generated a medium with 27 g L-1 of reducing sugars (hydrolysis efficiency= 32%). The hydrolyzed product was fermented and produced 11 g L-1 of ethanol (volumetric productivity=1.38 g L-1 h-1 and ethanol yield on substrate consumed=0.45 g g-1). In vivo experiments (DL50) revealed a reduction of roughly 240 times in the CBC toxicity (2.11 µg g-1).

Educación y bilingüismo en el Estado español = Education and bilingualism in the Spanish territory

This article looks at the treatment of languages in the communities in Spanish territory, which apart from Spanish have another language. At the beginning we discuss some questions which are relative to social cohesion in those territories where more than one language is spoken and we defend bilingual education as a good instrument in favour of it. At the same time we look at the concept of bilingual education and the assumptions that it bears in respect of the learning of languages. In this sense we discuss the conditions of acquisition of language and its appearance in the area of bilingual education

The pre-history of cryoscopy: what was done before raoult?

Cryoscopy is considered one of the foundations of the modern theory of solutions and of physical chemistry. This paper shows in order the first regularities pointed out by several scientists on the subject, in the first chapter of its birth as a scientific discipline. The study is focused on the identification of the different steps that helped, first qualitatively and then quantitatively, to adjust the different classes of possible solutions, including those that formed hydrates, to a basic formulation that the French scientist François-Marie Raoult would later generalize in the law that bears his name.
