1. Easy and Simple SiO2 Immobilization of Lipozyme CaLB-L: Its Use as a Catalyst in Acylation Reactions and Comparison with Other Lipases
In this study, lipase from Candida antarctica B (Lipozyme CaLB-L) was successfully immobilized on SiO2 through adsorption and used to obtain (R)-(+)-esters derived from (R,S)-1-phenylethanol. The new immobilized enzyme was compared with commercially immobilized lipases (Novozyme 435, Lipozyme 435 and Pseudomonas cepacia (PSC-II and PSD-I)). Lipozyme CaLB-L a

3. Participação do L-NAME, da L-arginina e da N-acetilcisteína no enfisema pulmonar induzido por fumaça de cigarro em camundongos / The lung remodeling in mouse emphysema is independent of nitric oxide modulation
Nitric oxide (NO) represents one of the most important intra and extracellular mediators/messengers. It takes part in both biologic and pathologic processes. This study aimed to verify NO role in pulmonary emphysema induced by cigarette smoke (CS) in mice. So L-NAME (LN) (a NOinhibitor) and L-arginine (LA) (a substract for NO formatio

5. Influência da orientação, sombreamento e substrato de ninhos-armadilha na captura de espécies de abelhas e vespas nidificantes em cavidades preexistentes. / Trap nests orientation, shading and substract influence in caught trapnesting bees and wasps
A utilização de ninhos-armadilha provê informações importantes acerca da biologia das espécies abelhas e vespas nidificantes. Entretanto, o conhecimento sobre os fatores que influenciam o manejo dessas espécies ainda é escasso. O presente estudo analisou parâmetros da estrutura da comunidade (abundância, riqueza, composição e predominância de es

6. Souls in flames : "The stories of the Rabi" under Martin Buber s thought / Almas em fogo : as "Historias do Rabi" sob o pensamento de Martin Buber
I intend to study the hassidic stories colected by Martin Buber on a book titled Die Erzählungen der Chassidim, under the principles of Buber s Dialogic Philosophy, mainly the principle-words I-Thou and I-It. As a cultural substract, I deal with the polish hassidic cultural environment on early 18th and late 19th centuries, in East and Middle Europe. This e

7. âUntil death turn us partâ and other fields of the collective imaginary of psychology students on sexuality / "Atà que a morte nos separe" e outros campos do imaginÃrio coletivo de estudantes de psicologia sobre sexualidade
This research aims to psychoanalytically investigate the collective imaginary of psychology students on sexuality. For this, we did a group interview organized around the Drawing-Stories with Theme Procedure, develop by Aiello-Vaisberg based in TrincaÂs Drawing-Stories Procedure. The obtained material was considered in the psychoanalytical method, opereted

8. Efeitos da salinidade sobre a germinaÃÃo e o desenvolvimento inicial do pinhÃo-manso (Jatropha curcas L.) / Salinity effects on the germination and initial development of Jatropha plants (Jatropha curcas L.)
This research was carried to evaluate salinity effects on initial development of Jatropha plants through two experiments. The first, to evaluate the effects of salinity on the germination was conducted at the Laboratory of Seed Analysis (LAS), Federal University of Lavras (UFLA) in Lavras-MG, Brazil. Jatropha seeds were exposed to seven salinity concentratio

9. Estudo sistemático do freamento de íons pesados em sólidos no regime de baixas velocidades / Systematic study of heavy ions stopping in solids at the low velocity regime
The energy loss of ions in materials is an important issue not only because of its direct applications on material analysis techniques, but also for the understanding of the interactions. Accurate knowledge of heavy ion stopping power at low energies is necessary in materials science as well as in basic physics, e. g. in the Doppler Shift Attenuation Method

10. Development of palladium nanoparticle catalysts for hydrodechlorination reaction / Desenvolvimento de catalisadores de paládio nanoparticulado para a reação de hidrodescloração
The hydrodechlorination reaction (HDC) has received great attention as an alternative treatment of organic residues, which is more efficient than incineration, especially for aromatic organic compounds, and avoids the formation of toxic species, such as furans and dioxins. The present study is focused on the preparation of supported palladium nanocatalysts f
