Alkali activation is a rapidly developing area in the global materials research and development community. It is based on alkali aluminosilicate chemistry with primary focus on the activation of solid aluminosilicate ...

Nanomedicine has gained a lot of attention as a potential solution in theragnosis of cancer. With the introduction of nanoscale metallic oxide materials, imaging techniques, disease detection, and treatment modalities could ...

The high temperature superconducting cuprates show some non Fermi liquid behaviour in their normal state. Also there is no generally accepted theory of high temperature superconductivity. The BCS theory has failed to ...

Barite is an exceptional non-metallic mineral composed of barium sulphate and it is used mainly by the oil and gas industry as drilling mud in deep drilling, where high pressure is encountered. The specific gravity of ...

The main challenge of heavy oil (bitumen) is the high viscosity making it not flow easily to production wells at normal reservoir conditions. Thermal recovery methods are used to exploit heavy oil reservoirs, where oil ...

Increasing oil recovery has been one of the issues enlisted for attention in oil producing countries around the world for past decades. So many forms of oil recovery techniques have been considered; infill drilling of new ...

System control has grown from manual control where humans sense the environment, analyse the result and determine control actions to semi-automated control. In semi-automated control sensing is done by sensing devices and ...

Down-hole temperature and pressure data are important information needed to understand flowing conditions and production optimization. For example, knowing the wellbore temperature profile is useful in predicting the wax ...

Access to the Internet is becoming more affordable especially in Africa and with this the number of active social media users is also on the rise. Twitter is a social media platform on which users post and interact with ...

The wavelet tree is a flexible data structure that permits representing sequences S[1; n] of symbols over an alphabet of size (n), within compressed space and supporting a wide range of operations on S. It has been used ...

The concept of dumpflooding is to flow water from a high pressure aquifer zone to a low pressure oil producing zone by natural force of gravity through a well connecting the two zones to enhance oil sweep into a producing ...

The advent of nanotechnology together with Biomedical Microelectro-Mechanical Systems (BioMEMS) for improved efficacy in treatment of cancer has resulted in the development of an implantable biomedical device for localized ...

The study explores the potential effects of the remote application of cyclic magnetic field to the female anopheles mosquitoes that carry malaria parasites. The goal is to develop a theoretical basis that can guide the ...

In this thesis, we present a theoretical study on the current-induced nucleation and propagation of antiferromagnetic skyrmionium. A skyrmionium, also known as 2π-skyrmion, is a vortex-like magnetic structure characterized ...

In the estimation of most reservoir parameters in well test, the reservoir is assumed to be isothermal which is practically not true due to the fact that there are heat sources due to friction in the wellbore, works done ...

Magnetohydrodynamics (MHD) boundary layer flow problems have become important in industrial manufacturing processes such as plasma studies, chemical engineering, electrochemistry, polymer processing, petroleum industries, ...

Graphene is an effectively two dimensional form of carbon atoms arranged in honeycomb lattice. Due to its lightweight, high electron mobility and other special electronic properties it is considered both an academically ...

We have studied a model for a non-collinear but coplanar antiferromagnetic spin texture on a two dimensional kagome lattice structure in the presence of Dzyaloshinskii-Moriya Interaction (DMI). We observed some interesting ...

Density-Functional Theory (DFT) offers a simplification to electronic structure problems by using the electron density instead of the wave-function. Unlike the wave-function which is a function of 3N variables (excluding ...
