Using Ultrasound to Effectively Homogenise Catalyst Inks: Is This Approach Still Acceptable?

Is this (still) a man's world?

During the past 50 years, the participation of women in medicine has increased dramatically. However, this encouraging influx has not been accompanied by equality for male and female faculty in terms of rank attainment, leadership roles and salaries. There is considerable evidence that women are still under-represented in the higher echelons of academic medicine, either as heads of departments,...

Is data gathering the only acceptable approach to biological science?

parasites of lizards has recently become the subject of sectional interests. In the absence of any objective criteria for classifying the group, two nomenclatures have come into current usage. Workers with interests in the natural history of the lizard parasites have emphasized the features that distinguish lizard and mammalian parasites and have tended to give the lizard parasites generic rank...

Ultrasound assisted oxidation of various alcohols to corresponding aldehydes by using Al2O3 as catalyst

A convenient approach for oxidation of structurally diverse alcohols has been developed using KMnO4 as oxidant agent in the presence of a catalytic amount of Al2O3 in aqueous acetonitrile. In this method various alcohols generally afforded the corresponding carbonyl compounds directly in good to high yield under ultrasound irradiation conditions. It shows that this kind of catalysis system is v...

Microsurgical reversal of sterilisation - is this still clinically relevant today?

INTRODUCTION Women with previous tubal sterilisation seeking fertility are faced with treatment options of reconstructive tubal surgery or in vitro fertilisation (IVF) techniques. The aim was to assess the current viability of tubal anastomosis in a local clinical practice. MATERIALS AND METHODS A retrospective cohort review of all sterilisation reversal cases from January 1998 to January 200...
