In [1,2,3], A. C. Baker and J.W. Baker studied the subspace Ma(S) of the convolution measure algebra M, (S) of a locally compact semigroup. H. Dzinotyiweyi in [5,7] considers an analogous measure space on a large class of C-distinguished topological semigroups containing all completely regular topological semigroups. In this paper, we extend the definitions to study the weighted semigroup ...

nitrosourea (BCNTJ) is shown in Chart 1. The back ground for the development of the nitrosoureas has been recently reviewed by Schabel et al. (4). Initial interest in the group of compounds of which BCNU is a member was stimulated by the finding of the Cancer Chemotherapy National Service Center screening program that i-methyl i-nitroso-3-nitroguanidine (NSC-9369) had weak activity against i.p....

The subject handled in this study is the determination of antioxidant activities of extracts obtained from the Urginea maritima (L.) Baker plant’s leaves and tubers. Extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. The antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. Moreover, the free radica...

We propose a generalization of the model of classical baker map on the torus, in which the images of two parts of the phase space do overlap. This transformation is irreversible and cannot be quantized by means of a unitary Floquet operator. A corresponding quantum system is constructed as a completely positive map acting in the space of density matrices. We investigate spectral properties of t...
