The i-δ relations are proved exact for structures wherein the neighbours of δ are not necessarily points of articulation, by generalizing Theorem I of Falk. An alternative proof and generalization of Theorem II of Falk is outlined reg...

Dilation theorems for Banach space valued stochastic processes and operator valued positive definite kernels are considered. It is shown, e.g., that a Banach space valued stochastic process X can be dilated to another process Y, if and ...

By using complex representation and GSVD of quaternion matrices, we define the norm of quaternion matrices, study the equality constrained least squares problem of quaternion matrices, give the necessary and sufficient conditions for th...

An inhibitor of cyclin-dependent kinase (CDK) has been well tolerated in Phase Ia clinical trials and is due to enter Phase Ib trials for glomerulonephritis (GN), a group of inflammatory kidney diseases, in autumn 2002. Details of this ...

The TiPS Lectures were inaugurated to promote interdisciplinary approaches to problems in Pharmacology. The First Annual TiPS Lecture was given at the FASEB meeting in Washington DC, 3 April 1990, by Jean-Pierre Changeux. The following ...

Fifty-two experimental locations spreading all over the Arab region are chosen. The locations belong to 21 Arab states. Monthly iso-radiation (isopaths) are then drawn. Maps for minimum solar, maximum solar and yearly average radiation ...

This paper introduces the concept of a partial geometry of dimension three, extending the concept of an (r, k, t) partial geometry (which may be called of dimension two) due to Bose. An association scheme is defined on this system which...

Using simulation techniques, the effect of optical errors on the flux distribution around absorber tubes of Parabolic Trough Concentrators (PTCs) were investigated. It is found that the total optical error has profound effect on the int...

This research presents the findings of a rank order evaluation of corporate social responsibility attributes by a target public (N = 72) of a contemporary corporate social responsibility campaign. The results indicate that pub...

Two new triterpenoids namely putranjivanonol, a hydroxy ketone, and putranjic acid, a hydroxy acid, have been isolated from the trunk bark of Putranjiva roxburghii Wall. (Euphorbiaceae) along with friedelin and putranjivadione and a ste...
