Tropical Africa has one of the world’s largest endowments in medicinal plant diversity. However, this potential has not been translated into pure drugs of proven efficacy and safety synonymous with modern pharmaceuticals. The basis for the slow translation of Tropical Africa’s medicinal plant wealth into value-added medicines acceptable in the doctor’s clinic is not clear. In this work, we sought to... Read more.

The international outsourcing of intermediate products is a common practice in manufacturing. Although outsourcing labor- and resource-intensive production to developing countries is based on financial motives, the decision should also be evaluated from an environmental perspective at a global scale. In this study, the environmental effects of four supply chain scenarios are analyzed through a life-cycle assessment... Read more.

The female condom is a relatively new product that is intended to serve the dual role of protecting against unwanted pregnancy and sexually transmitted infections (STI). Very few studies have been conducted on the use of female condom in Nigeria. Therefore, information is lacking about its continued use, particularly among women at high risk of HIV and other STI. With the above consideration, the Society for Family... Read more.

Diabetes mellitus (DM) has progressively increased in global prevalence. Recent studies have found that patients with DM may suffer from hearing impairment as a chronic complication. The effect of hearing loss may impair the quality of life of patients which affects functional, social, as well as psychological aspects. Both DM and hearing loss are considered to be associated, although this correlation remains elusive.... Read more.

This paper presents a physical model which describes the layer growth kinetics and the nitrogen concentration profiles during gaseous or plasma nitriding of pure iron. The model is related to a one dimensional moving boundary value problem where the initial concentration profiles are assumed to be linear and a new boundary condition at the diffusion zone is proposed. The model is solved by using a classical finite... Read more.

DNA microarray analysis is the main core in genome mapping. Each microarray image contains millions of information about genes. Microarray analysis is considered one of the most recent and important technologies in exploring the genome. One of the key steps in microarray analysis is to extract gene information from the gene spots, these information represent gene expression levels in the microarray. This paper proposes... Read more.

This paper proposes frequency response based identification of a parallel resonance transfer function in power systems including capacitor banks for power factor improvement. The proposed method is simple and easy to understand by finding undetermined coefficients. Only magnitudes of measured harmonic currents for some orders of both source and load are required. Validation of the proposed method is given in frequency... Read more.

The purpose of this paper was to address the issue of E-government website evaluation regarding the provision of a decision-making framework built around the concepts of website evaluation. The proposed framework deploys a Bayesian Belief Network (BBN) to conquer the subjectivity and inaccuracy that characterizes the conventional models for E-government website quality assessment. Since the developments of E-government... Read more.

Housing in Colombia, especially social housing, has been a priority issue for governments in recent years; however, it is necessary to consider building more sustainable homes with less environmental impact using local material as opposed to building with conventional materials. Based on these needs, this research aimed to evaluate the potential environmental impact of social housing by predominantly using local... Read more.

Web optimization is the process of optimizing the web to increase visibility or rank of websites in search engines. Furthermore, this process is also viewed from multiple perspectives, from optimizing inter-server communication that offers the best responses to users’ queries and provides targeted advertisements to users of a website. With this regard, the process of automatic classification and information... Read more.

Deformation analysis is crucial to applications in geodesy, structural engineering, and geology, of which the main goal is to detect the behaviors of a deformed body. Traditional deformation analyses rely on a limited number of observations and thus give a relatively poor description of the strain field on the entire object. In this study, a method based on the displacement gradient model and unified least-squares... Read more.

The study was conducted in Northern Ghana comprising of the Northern, Upper East and Upper West regions. The objective of the study was to analyse maize-based rain-fed vegetable production systems with a view to explore their potential to contribute to food and income security for rural households. A combination of qualitative and quantitative data collection methods were employed during the study. Questionnaires were... Read more.

Maintenance of microorganisms in mycology is of fundamental importance for retrospective and prospective studies that focus on their biology, etiology and epidemiology. The aim of this study was to evaluate the viability, contamination and morphological changes of endophytic fungi maintained under different preservation methods. We evaluated five preservation methods; constant sub-culturing, preservation under mineral... Read more.

We have successfully synthesized Samarium oxide (Sm2O3) doped borate glasses by conventional rapid melt quench method. The prepared batch was melted at suitable transition temperature and to improve the crystalline phases, glass was kept at 500°C for 7 h. The X-ray diffraction (XRD) pattern identified the amorphous nature of glass and photoluminescence emission properties proved the optical properties of Sm2O3 doped... Read more.
