ZnO-TiO2 composite formed by mixed oxides via polyol

Among the researches on preparation and test of nanostructured materials, titanium dioxide and zinc oxide have been the most frequent studied oxides. In order to extend their properties, composites have been prepared using three different methods: Polyol Method, Sol-gel Process and a combination of the two processes (hybrid process). Recent research showed best properties in composite materials than in pure oxides. In this work is presented the preparation and the structural characterization of ZnO-TiO2 composite nanostructures to be tested for their performance in electrocatalysis and in further trial on photovoltaic cells.

Recuperação em área de empréstimo usada para construção de usina hidrelétrica

The recovery of native area used in hydroelectric power station construction is a slow process, and it requires the use of covering plant as a source of organic matter, application of nutrients and amendments as soil conditioner. Thus, this study has the objective to study the recovery of physical attribute of subsoil in a distrophic Red Latosol, used in the embankment and foundation of Hydroelectric Power Station, Ilha Solteira, São Paulo, Brazil. The design used was randomized blocks with eight treatments and four replications. The research started in 1992. The treatments consisted of green manure, pasture and soil amendment. After 13 years, total porosity, macroporosity, microporosity, bulk density, aggregate stability, resistance to penetration, organic matter of soil and dry matter of pasture production were evaluated. The adopted treatments are slowly contributing towards recovery of physical attributes of exposed subsoil. The effects of the soil recovery are reaching 0-0.10 m depth.

Studies on anti-allergic constituents in the leaves and stems of Anchietia salutaris var. martiana (Violaceae)

The anti-allergic active fractionation of hexane extracts of the leaves and stems of Anchietia salutaris,ar. martiana (family Violaceae) nas performed by monitoring their activities with an in vitro bioassay system measuring the inhibitory effects on induced histamine release from guinea pig lung cells. Three known pentacyclic triterpenes (friedelin, alpha-amyrin, beta-amyrin) were isolated, but these compounds were inactive. Aliphatic hydrocarbons and methyl esters of fatty acids (palmitic, oleic, linoleic, linolenic acids) were detected in active fractions. All compounds isolated were detected for the first time in this medicinal plant.

The Intriguing Phospholipases A(2) Homologues: Relevant Structural Features on Myotoxicity and Catalytic Inactivity

Phospholipases A(2) homologues are found in the venom of Crotalinae snakes, being their main action related to myonecrosis induction. Although many studies on these toxins had already been performed, their mechanism of action remains unclear. Here, important aspects about these toxins are reviewed, including their correct biological assembly and how essential is the natural substitution D49K for their catalytic inactivity.

Altitude e coordenadas geográficas na estimativa da temperatura mínima média decendial do ar no estado do Rio Grande do Sul

O objetivo deste trabalho foi verificar, com dados de temperatura mínima média decendial do ar (Tm) de 41 municípios do Estado do Rio Grande do Sul, de 1945 a 1974, se a Tm pode ser estimada em função da altitude, latitude e longitude. Para cada um dos 36 decêndios do ano, realizaram-se análise de correlação, análise de trilha das variáveis causais - altitude, latitude e longitude - sobre o efeito Tm, e estimaram-se os parâmetros do modelo das equações de regressão linear múltipla, pelo método passo a passo, com teste para saída de variáveis, considerando Tm como variável dependente e altitude, latitude e longitude como variáveis independentes. Na validação dos modelos de estimativa da Tm, usou-se o coeficiente de correlação linear de Pearson, entre a Tm estimada e a Tm observada em dez municípios do Estado, com dados da série de observações meteorológicas de 1975 a 2004. A temperatura mínima média decendial do ar pode ser estimada pelas coordenadas geográficas em qualquer local e decêndio, no Estado do Rio Grande do Sul. A altitude e latitude explicam melhor a variação da Tm.
