The UbuntuNet Alliance, a consortium of National Research and Education Networks (NRENs) runs an exclusive data network for education and research in east and southern Africa. Despite a high degree of route redundancy in ...

Reservoir development planning and well placement significantly affect hydrocarbon recovery. Therefore, strategic well placement and development techniques are essential to minimize the risk of unproductive drilling and ...

In the context of digital heritage archives, we find heritage objects having intrinsic contextual and historical information. Capturing all that information is difficult, especially if that effort is left only to the ...

A review of national health records (NEHR) systems shows that privacy and security risks have a profound impact on the success of such projects. Countries have different approaches when dealing with privacy and security ...

Due to rapid industrialization, the demand for heavy metals is ever increasing, but the reserves of high-grade ores are diminishing. Therefore there is a need to explore alternative sources of heavy metals. Ore mine gangues ...

This research presents the design, construction, and analysis of the performance of a mixed-mode solar dryer for crops. A mixed-mode solar dryer utilizes direct solar radiation from the sun as well as input heat ducted ...

Organic-inorganic perovskite photovoltaics (PVs) have attracted a lot of attention as high- efficiency thin film PVs which are relatively cheap and easy to fabricate. Lead halide perovskites have shown a rapid rise in power ...

Topsoil stripping, drilling and blasting extraction, waste rock dumping, loading, and unloading, crushing and screening, and materials transport are among other activities involved in iron ore mining. These activities ...

Titanium alloy is popular in biomedical application owing to its low density, good biocompatibility (i.e. biological and chemical inertness) and excellent mechanical properties. Due to the high disparity between the implant ...

This work is aimed at studying activated carbons as supercapacitor electrode materials derived from plant biomass waste materials. The activated carbon raw materials are sourced from coconut shell, pine cone and rice husk ...

This work studies the adsorption capacity of laterite and iron oxide nanoparticles for dissolved ions in solution and therefore its ability to reduce conductivity of mine waste effluent. Three laterite samples were prepared ...

Materials selection is done regarding to the availability, cost and performance of the candidates. In buildings, cement is the material that is widely used, even though it is releases co2 (estimated about 7% of the worldwide ...

The Luteinizing Hormone-releasing Hormone (LHRH); also known as a Gonadotropin-Releasing Hormone can be utilized for targeted therapy with cytotoxic analogs, in which prodigiosin is linked to the [D-Lys6] LHRH. Our studies ...

One of the unintended impacts of crude oil exploration is the pollution of agricultural land and aquatic resources when there is accidental oil spillage. The environmental effect of this has resulted in untold hardship to ...

In recent times, the rate of growth in information available on the internet has resulted in large amounts of data and an increase in online users. The Recommendation System has been employed to empower users to make ...

Many Institutions offer on-line courses to people from all around the world. Learning Management Systems provides a convenient learning environment for on-line courses. Each learner has individual needs and characteristics ...

The Opportunistic network is an interesting development in the Mobile Ad hoc Network (MANET) environment. It has no end-to-end connectivity among nodes. Unlike MANETs, the nodes in Opportunistic network are independent on ...

The Java programming language is widely used in industry and business. Therefore, academic institutions worldwide include Java learning as a basic part of their Computer Science and Engineering curricula. At the same time, ...

Traffic simulation has become one of the most used approaches for traffic analysis in support of the design and evaluation of traffic systems. Although traffic flow models have been applied for almost a century to describe, ...

We use two-dimensional direct numerical simulations of Boussinesq stratified shear layers to investigate the influence of the minimum gradient Richardson number Rim on the early time evolution of Kelvin–Helmholtz instability ...
