The Importance of Simulation in Team Training on Obstetric Emergencies: Results...

Obstetric emergencies are unexpected and random. The traditional model for medical training of these acute events has included lectures combined with sporadic clinical experiences, but this educational method has inherent limitations. Given the variety of manual skills that must be learned and high-risk environment, obstetrics is uniquely suited for simulation. New technological educational tools provide an opp...

Chorionicity and perinatal complications in twin pregnancy: a 10 years case ser...

OVERVIEW AND AIMS: Multiple pregnancy accounts for about 3% of all pregnancies. The monochorionic pregnancy presents a relatively constant incidence (1:250 pregnancies) unlike the dichorionic, which is influenced by race, heredity, maternal age, parity and medically assisted procreation. The purpose of this work was to evaluate the impact of chorionicity on perinatal morbidity of twin pregnancy.Retrospective, l...

Remoção de metais pesados por biofilmes suportados em carvão activado

Remoção de crómio de efluentes industriais por biossorção

Os processos físico-químicos clássicos, quando aplicados na remoção de metais pesados presentes em efluentes de baixa concentração e elevado caudal, revelam-se pouco eficientes e demasiado onerosos, sobretudo para as unidades industriais de pequena e média dimensão que proliferam no nosso país. Apesar de diluídos, esses efluentes tornam-se uma ameaça ambiental à escala local e cumulativa. Dentro das novas tecno...

Desenvolvimento de biossorventes para remoção de crómio de efluentes industriais

The removal of Cr (III) and Cr (VI) from water solutions by biosorption on an Arthrobacter viscosus biofilm supported on a granular activated carbon was studied and is presented. The following parameters were considered: concentration of hexavalent Cr, concentration of trivalent Cr, competition with other metal, Cd, and cellular viability. The biofilm was kept active in different growth media and afterwards suf...
