The known 2-aryl-6,8-dibromo-2,3-dihydroquinolin-4(1H)-ones 122 were dehydrogenated using thallium(III) p-tolylsulfonate in dimethoxyethane under reflux to afford the 2-aryl-6,8-dibromoquinolin-4(1H)-ones 136. Palladium-catalyzed ...

Mechanistic aspects of phosphorylation, dephosphorylation, pyrophosphorylation and depyrophosphorylation reactions that mimic phosphorylases, dephosphorylases, pyrophosphorylases and depyrophosphorylases have been studied ...

Opsomming Daar bestaan 'n behoefte aan 'n objektiewe maatstaf om die gehalte van akademiese publikasies te bepaal en te vergelyk. Hierdie navorsing het die invloed of reaksie wat deur 'n publikasie gegenereer is uit ...

The ascent of the current industrial revolution known as Industry 4.0 (I40) or smart manufacturing is considerably impacting the manufacturing sector with the utilization of more intelligent and advanced practices such ...

Some Epidemic models with fractional derivatives were proved to be well-defined, well-posed and more accurate [34, 51, 116], compared to models with the conventional derivative. An Ebola epidemic model with non-linear ...

The syntheses of aromatic oxazolyl functionalized chain end polystyrene and poly(methyl methacrylate) using an oxazolyl functionalized initiator in atom transfer radical polymerization were effected by the following ...

Poor management attitude has been identified as the major challenge to software project management. Lack of knowledge and understanding of other pertinent risk factor dimensions in software projects (such as potential ...

Developing countries like Tanzania experience challenges towards utilization and acceptance of ICT; calling for a need to further research on the concept. Open Source (OS) usage is a potential strategy for addressing such ...

In our pursuit of ever smaller transistors, with greater computational throughput, many questions arise about how material properties change with size, and how these properties may be modelled more accurately. Metallic ...

In this thesis contributions to the solution of the generalised knapsack problem are given and discussed. Attention is given to problems with functions that are calculable but not necessarily in a closed form. Algorithms ...
