while the hydrological balance of forest ecosystems has often been studied, quantitative studies on the seasonal variability of rainfall interception (i) and canopy storage capacity (s) by individual trees are less frequently reported. hence, the effects of the seasonal variation in i and s by individual persian oak trees (quercus brantii var. persica) in the zagros forests of iran were studied...

Clotrimazol é reduzido em eletrodo de mercúrio em tampão fosfato pH > 6 através de um processo reversível de um elétron. O processo eletródico apresenta forte efeito de adsorção, o qual pode ser minimizado na presença de Triton X-100. Clotrimazol pode ser determinado em níveis de 50 ng mL-1 quando pré-acumulado durante 3 min à –0,20 V. O método proposto foi aplicado para determinação do fármaco...

He became interested in surgery during his undergraduate studies, particularly in experimental surgery (general and cardiovascular) and cardiopulmonary bypass (under the supervision of Dante Romanó). He did his residency in Cardiovascular Surgery at the Instituto de Cardiologia do Estado de São Paulo (ICE), currently, the Institute Dante Pazzanese de Cardiologia, in 1964 and 1965, remaining at ...

A thermoanalyical study of pure atenolol and a commercial tablets containinf the drug were carried out using thermogravimetric (TG) and differencial scanning calorimetry (DSC) techniques. Nonisothermal method was employed to determine kinetics data of decomposition process. In order to evaluate interaction observed in the commercial tablets, compatibility studies of drug and excipients (microcr...

Answering a question of Pereira we show that it is possible to have a model violating the Singular Cardinal Hypothesis without a tree-like continuous scale.

Two experiments were conducted, aimed at improving the practicability of the method for transcervical embryo collection in Boer goats described by Pereira et al. [Pereira, R.J.T.A., Sohnrey, B., Holtz, W., 1998. J. Anim. Sci. 76, 360-363]. Invention of a hammock-like restraining device, use of a wider-bore flushing catheter and a modified flushing mode contributed toward this end. The importanc...

The previous decade has seen a variety of trends and developments in the area of communications and thus multimedia access. While individual, isolated developments produced small advances on the status quo, their combination and cross-fertil ization resulted in today’s complex but exciting landscape. In particular, we are beginning to see delivery of all types of data for all types of users in ...
