Implementation evaluations, also called process evaluations, involve studying the development of programmes, and identifying and understanding their strengths and weaknesses. Undertaking an implementation evaluation offers insights into evaluation objectives, but does not help the researcher develop a research strategy. During the implementation analysis of the UNAIDS drug access initiative in ...

Investigation of nonspecific interactions of metal ions with proteins and studies of biological function of such complexes are of importance (Breslow 1978; Friedberg 1975). Identification of the binding centers of metal ions with proteins and determination of the binding constants are necessary to explain the transfer mechanisms of these ions by proteins. Earlier it has been shown (Lau et al. 1...

The overwhelming appeal of the concept of evolution through natural selection has focused the minds of generations of biologists on trends, and the similarities and differences between organisms that is grist to the mill of taxonomists. “To paraphrase T.S. Eliot, ‘Where is the imagination that has been lost in knowledge and where is the knowledge that has been lost in information?’ This book is...

Non-topological solitons are localized classical field configurations stabilized by a Noether charge. Friedberg, Lee, and Sirlin proposed simple renormalizable soliton model in their seminal 1976 paper, consisting of complex scalar that carries the charge real-scalar mediator. We revisit this model, point out commonalities differences with Q-ball solitons, provide analytic approximations to und...

The different behaviour of total and partial numberings with respect to the reducibility preorder is investigated. Partial numberings appear quite naturally in computability studies for topological spaces. The degrees of partial numberings form a distributive lattice which in the case of an infinite numbered set is neither complete nor contains a least element. Friedberg numberings are no longe...
