The European Energy Performance of Buildings Directive (EPBD) explicitly refers to a "passive cooling techniques, primarily those that improve indoor climatic conditions and the microclimate around buildings". However, in Europe the demand for air conditioning is rising, especially in office buildings and is expected that the cooled floor area will be four times higher in 2020 when compared with 1990 figures. A...

We have developed a method to obtain polymer hybrids with control of inorganic content and molecular configuration. Hybrid poly(methyl methacrylate) (PMMA) was obtained via atom transfer radical polymerization (ATRP) initiated by octafunctional cubic silsesquioxanes using CuCl as catalyst. Two different ATRP initiators obtained by attaching specific chemical groups to the cubic silsesquioxane were employed to p...
The subespecie Lutreolina crassicaudata paranalis Thomas, 1923 is validated through analysis of variance of 13 craniometrical measurements. There is significam separation for sex in 10 of 13 craniometrical measurements. The possibility of validation of subespecies L. c. bonaria Thomas, 1923 through coloration variation is discussed.
This is a study of the effects of irradiated glucose-saline solutions (60Co, 105 R at a dose rate of 1.7 X 106 R/h) on tumors induced by the intravenous injection of dimethylbenzanthracene (DMBA) in female Sprague-Dawley rats. Each animal received 10 cc intraperitoneal injections of the irradiated solution spaced over 17 days. As a control two groups of tumor bearing animals were used: one received irradiated i...
