Impact of composition and morphology on the optical properties of Si-NC/P3HT th...

Blends of Si nanocrystals (Si-NCs) and organic semiconductors are promising materials for new optical and electronic devices processed from solutions. Here, we study how the optical properties of composite films containing Si-NCs and the organic semiconductor poly(3-hexylthiophene) (P3HT) are influenced by the composition and morphology resulting from different solution-processing parameters and different solve...

Effects of moderate electric fields on aggregation of whey protein solutions an...

Effects of moderate electric fields (MEF) on denaturation of whey proteins solu...

Electric fields application during thermal processing are now receiving increased attention due to uniform heating of liquids and extremely rapid heating rates, which presumably enables higher temperatures to be applied without inducing excessive denaturation of the constituent proteins [1]. The aim of this work was to evaluate the effects of moderate electric fields (MEF) on denaturation kinetics and thermodyn...

Effects of electric fields on protein unfolding and aggregation : Influence on e...

Electric fields application is receiving increased attention because of its uniform heating of liquids. The mechanisms of unfolding and aggregation of whey proteins during ohmic heating may influence properties of edible films made thereof. The aim of this work was to evaluate the effects of ohmic heating on physical and structural properties of whey protein edible films and compare them with those obtained by ...

Environmental impact of novel thermal and non-thermal technologies in food proc...

During the last 25 years, consumer demands for more convenient and varied food products have grown exponentially, together with the need for faster production rates, improved quality and extension in shelf life. These requests together with the severity of the traditional food processing technologies were driving forces for improvements in existing technologies and for the development of new food preservation t...

Técnicas cirúrgicas para urolitíase obstrutiva em pequenos ruminantes: relato d...

Relataram-se dois casos em que a penectomia com transposição peniana perineal foram as técnicas cirúrgicas de escolha e que resultaram em 50% de sucesso. Quatro casos em que as cistotomias seguidas de cistostomias apresentaram 100% de sucesso, um caso em que só a cistotomia foi realizada e não se obteve sucesso, um caso em que apenas o tratamento clínico foi eficiente e dois casos em que houve 100% de insucesso...

Fertility of male adult rats submitted to forced swimming stress

We investigated whether stress interferes with fertility during adulthood. Male Wistar rats (weighing 220 g in the beginning of the experiment) were forced to swim for 3 min in water at 32ºC daily for 15 days. Stress was assessed by the hot-plate test after the last stressing session. To assess fertility, control and stressed males (N = 15 per group) were mated with sexually mature normal females. Males were sa...
