Parker [1960] has derived the magnetic field configuration in interplanetary space that would result from a steady solar wind flowing radially with uniform velocity from all heliolongitudes. Ahluwalia and Dessler [1962] have pointed out that the Archimedes spiral formed by the field lines would corotate with the sun even though the plasma moves radially. In this note we examine conditions in interplanetary space along the solar equatorial plane that are likely to arise when the radial velocity of the solar wind is a function of solar longitude, a most likely possibility judging by localized zones of enhanced coronal temperatures and intensity of 5303°λ which are observed on the sun. Moreover, we consider some broad consequences of the growth and decay of regions of activity and enhanced wind velocity as a function of time.

The burden of disease in patients with congestive heart failure is high. The future of BNP looks promising as it may be a better diagnostic tool for the diagnosis of CHF in developing countries in new millennium. Natriuretic peptide hormones, a family of vasoactive peptides with many favourable physiological properties, have emerged as important contenders for development of diagnostic tools and therapeutic agents in cardiovascular disease. Measurement of B-type natriuretic peptide has become as an easy-to-perform bedside test. The clinical and diagnostic significance of the measurement of plasma Nt-proBNP in the diseases of the cardiovascular system with particular emphasis on the assessment of patients with heart failure and their effects on predicting survival rate. The plasma levels of Nt-proBrain Natriuretic peptide responds more vigorously after myocardial infarction than those of other natriuretic peptides. This article is an attempt to give a short overview on the utility of BNP-blood levels for the diagnosis and treatment of heart failure.
