The role of endothelin (ET) receptors was tested in volume-stimulated atrial natriuretic factor (ANF) secretion in conscious rats. Mean ANF responses to slow infusions (3 x 3.3 ml/8 min) were dose dependently reduced (P < 0.05) by bosentan (nonselective ET-receptor antagonist) from 64.1 +/- 18.1 (SE) pg/ml (control) to 52.6 +/- 16.1 (0.033 mg bosentan/rat), 16.1 +/- 7.6 (0. 33 mg/rat), and 11.6...

It is still uncertain whether teacher professional development in great demand, especially the field of educational research. This research aimed as preliminary to determine gaps be taken, those related programs (PDPs) at elementary level during last decade. The method used was a computational mechanism using several applications such Publish or Perish, Microsoft Excel, and VOS viewer. number P...

Background: Soybean [Glycine max (L.) Merrill] is a self-pollinated diploid leguminous crop (2 n=40) originated from China. It called as ‘Cow of the field’ or ‘Gold soil’ because high oil and protein content. The objective study to determine genetic diversity using cluster principal component analysis among 135 soybean germplasm. Methods: experiment was conducted at Department Pulses, Tamil Nad...

Although the Fourier Transform is the traditional frequency domain analysis tool in communications systems, other transforms are pointed out in the context of orthogonal series representation of periodic signals. Last year, we became interested in the Walsh Transform and developed virtual instruments (VIs) to compute the Walsh transform, to generate the Walsh basis functions and modified LabVIE...

High-resolution X-ray observations of the face-on galaxy M 83 with the HRI onboard ROSAT are presented. The analysis aimed at studying the X-ray point source population inside the galaxy and disentangling the X-ray emission components (i.e. point sources, extended emission from hot gas in the bulge, disk and halo). Within the D25 ellipse of M 83, 21 X-ray sources are detected with (0.1–2.4 keV ...
