1. Management of severe male infertility with special reference to IVF and ICSI
Abstract : Background: Until recently the treatment options for couples with severe male factor infertility have been restricted. With the advent of intracytoplasmic sperm injection (ICSI) it has now become possible to offer these couples effective treatment. READ MORE

2. Chemical and Morphological Characterisation of Aerosol Particles in the Tropopause Region
Abstract : The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. READ MORE

3. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis
Abstract : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. READ MORE

4. Volcanic Aerosols in the Upper Troposphere and Stratosphere – Aircraft- and Satellite-Based Observations
Abstract : Volcanic eruptions are the largest source of variability in the stratospheric particle concentration as they inject SO2 that is subsequently converted into sulphate particles. No major perturbation of the stratospheric aerosol load has been observed since the large eruption of Pinatubo in 1991, but several moderate eruptions after 2000 have caused deviations from stratospheric background conditions.

5. Strategies for infertility treatment in men with azoospermia
Abstract : Introduction: Historically, treatment of severe male infertility has been restricted. With the introduction of intracytoplasmic sperm injection (ICSI), infertile men have been given new hope of achieving genetic fatherhood. READ MORE
