Thermomechanical environment characterisation in injection moulding and its rel...

This study is focused on the establishment of relationships between the injection moulding processing conditions, the applied thermomechanical environment (TME) and the tensile properties of talc-filled polypropylene,adopting a new extended concept of thermomechanical indices (TMI). In this approach, TMI are calculated from computational simulations of the moulding process that characterise the TME during proce...

Effect of the Impact Conditions on the Mechanical Properties of Injection-Molde...

This work focused on the study of the impact event on molded parts in the framework of automotive components. The influence of the impact conditions and processing parameters on the mechanical behavior of talc-filled polypropylene specimens was analyzed. The specimens were lateral-gate discs produced by injection molding, and the mechanical characterization was performed through instrumented falling weight impa...

Siolmatra brasiliensis (Cogn.) Baill., Cucurbitaceae, acute toxicity in mice

Siolmatra brasiliensis (Cogn.) Baill., Cucurbitaceae, commonly known as "pluméria" or "taiuiá", is widely used in different ways in Brazilian popular medicine to treat several diseases. Acute toxicity of Siolmatra brasiliensis crude ethanolic extract (CEE) was investigated in mice. No mortality or signs of CEE toxicity were observed at the doses of 10 and 100 mg/kg bw, but the administration of 1000 and 2000 mg...

Polímeros com capacidade de reconhecimento molecular no controlo da libertação ...

Molecularly imprinted polymers (MIPs) consist of synthetic macromolecular matrix, obtained through molecular imprinting-based methods that show ability to selectively recognize important biological molecules and its application in the drug delivery field is under development. In the present review the main aspects related to the synthesis and characterization of MIPs are studied. The fundamental variables parti...

Uma implementação do protocolo de roteamento Multi-Geo para redes de sensores s...

Este trabalho apresenta o Multi-Q, uma versão modificada do Multi-Geo, que é um protocolo adaptativo híbrido para Redes de Sensores Sem Fio (RSSFs) cujo comportamento é baseado no tráfego da rede em um dado momento. Ele usa um comportamento reativo quando a frequência de eventos é baixa e um comportamento proativo quando a frequência de eventos aumenta. A principal diferença entre a nova versão e a anterior é o...

Disseminated toxoplasmosis presenting as sepsis in two AIDS patients

This report describes two patients who presented acute disseminated and severe toxoplasmosis as the first opportunistic disease related to acquired immunodeficiency syndrome. At admission, clinical and laboratory findings were similar to sepsis or septic shock and a fast evolutive course to death occurred in both cases. At necropsy, an inflammatory reaction and presence of a great number of Toxoplasma gondii cy...
