Objective: The radial artery is becoming popular as a conduit for coronary artery surgery but there is concern about its tendency to vasospasm. Diltiazem is used clinically in an effort to prevent vasospasm but there are suggestions that it is relatively ineffective. The ®rst aim of the study was to test the effectiveness of Ca antagonists against vasospasm(More)

Monsoon plays a critical role in triggering environmental features such as seawater temperature, salinity, dissolved oxygen content and nutrient generation which in turn become responsible for production of phytoplankton and zooplankton. Along the southwest coast of India the intensity of southwest monsoon as evidenced by annual rainfall showed a declining(More)
Stepwise etching of lunar soil ilmenite grains reveals that the 15N/14N ratio of implanted nitrogen decreases with increasing implantation depth within the ilmenite grains, i.e., with increasing energy of implantation. These results show that N derived from solar energetic particles, NSEP, is enriched in the light isotope, 14N, relative to solar-wind(More)
We identify Martian interior, radiogenic and fission components in recently recovered shergottites, which further constrain the differentiation and evolution of the mantle. Introduction: The duration of accretion of Mars as judged from extinct radionuclides was shorter than that of Earth and could have lasted a few Ma, whereas terrestrial accretion lasted(More)
