Reliable solar radiation data are essential to study the feasibility and to determine the optimal size of solar plants in a particular location. However, the network of solar radiation measurement stations is very weak around the world. This has led to the development of a wide variety of models and techniques for estimating solar radiation from commonly measured meteorological variables (Ambient air temperature, relative humidity, wind velocity …). In this work, 22 empirical models,...

This research is carried out with Algerian architecture students in a didactic framework which aims to demonstrate the process of defining architectural bias in the Algerian and, by extension, Mediterranean urban landscape.Many Algerian cities no longer have their character despite regional, climatic and socio-cultural particularities.The old urban fabrics are gradually transformed into precarious housing zones, concerned by a policy of resorption which disintegrates them, annihilating any...

This study investigated the organochlorine pesticides content of Atuh wetland for its suitability for cage aquaculture in schools as a tool for reshaping education in Nigeria. The study answered 3 research questions and tested a hypothesis. To achieve these, the research area Atuh wetland Ugiliamai has mapped 5 research blocks. From each of the research blocks water samples were collected from 10 spots bulked, a composite drawn and fixed with HN0 3 and kept in an ice-cooled box for...

There is no comprehensive report of neurosurgery postgraduate education in Africa. This narrative review aimed to map out the landscape of neurosurgery training in Africa and highlight similarities and differences in training. The keywords “neurosurgery,” “education,” and “Africa” were searched on PubMed and Google Scholar from inception to January 17, 2021. Next, a complementary hand search was conducted on Google using the keywords “neurosurgery,” “residency,” and the individual African...

Abstract— This paper introduces a case study of the Egyptian E-Learning University (EELU) as the first higher education institution in Egypt that adopts e-learning model for teaching and learning. The EELU case study presents the experience of applying the characteristics and framework of e-universities. The objective of the author is to help the reader understand what has been set out to do and how, and to convey lessons learned. The paper begins with an introduction section to familiarize...

Our study provides an evaluative and a reflective analysis of doctoral business training in Africa to help develop a deeper understanding of the challenges and realities in increasing the Doctor of Philosophy (PhD) production in business/management. We begin by framing the context and structure of PhD programs in Africa. Using an illustrative sample of ten African business schools from five countries and available secondary data and reports on Africa's doctoral business training programs, we...

Using new satellite data from the European Space Agency's Sentinel-5P system, this article investigates the spatial and temporal dynamics of vehicular traffic congestion, air pollution, and the distributional impacts on vulnerable populations in Dar es Salaam, Tanzania. The metro region's rapid growth in vehicle traffic exceeds road network capacity, generating congestion, transport delays, and air pollution from excess fuel use. Dangerously high pollution levels from tailpipe emissions put...

The aim of this study was to investigate how Professional Learning Communities (PLCs) could help to improve the teaching and learning outcomes of business education subjects in Botswana secondary schools. A qualitative methodology was adopted and data were collected online through WhatsApp chats and calls. Through analysing interviews and reviewing of documents related to PLCs in schools, we were able to code data into categories that emerged from themes and that assisted in understanding...

Introduction Voluntary HIV testing is a vital preventive measure to reduce HIV transmission. Existing evidence on the association between HIV-related knowledge and HIV testing service utilisation shows inconsistent findings. Therefore, the aim of this review is to assess whether knowledge of HIV is related to improvement in voluntary HIV testing service utilisation among university students in Sub-Saharan Africa. Methods and analysis A systematic review of studies on the association of...

Abstract Education is a key to success for every member of the society. And we emphasize this principle by saying that education changes the world as anything can be transformed with education. In many countries, especially African societies, people do focus on education for male child leaving behind the girl. But if we look at the recent updates on population of our countries, it shows that females are in higher population than males. Therefore, if this larger population does not get...

Urbanisation of riverine landscape is an increasing threat to the functionality of river ecosystems. In this study, we identify and classify macroinvertebrates indicator signature traits and ecological preferences.We hypothesised that urban pollution would differentially influence the distribution of macroinvertebrate traits and ecological preferences along a gradient of water quality deterioration. Hence, we identified and classified potential biological indicators traits and ecological...

One of the persistent environmental issues today is high noise levels in residential areas especially in the developing countries. There are several unorganized informal sector activities such as recreational, road traffic, household and religious activities, operation of power generating sets, incompatible uses in space among others that are the sources of noise pollution in residential areas. A number of empirical studies have been carried out on the impact of noise on residential property...

Understanding lake evaporation and the climate change role in evaporation is paramount for any water resources management system. The prediction of the climate's future changes is a very important step in planning lake future management decisions. This study analyzed Lake Nasser's evaporation in southern Egypt. Meteorological parameters were compiled from Aswan meteorological station near Lake Nasser. Also, CORDEX predicted climatological parameters from 2021 to 2050 were collected. Lake...

The work was aimed to assess the heavy metals concentrations in the Sharkia Governorate, Egypt. The determination of heavy metal bioaccumulation and their antioxidant alterations on Oreochromis niloticus were considered. The gonads and the liver of the fishes were analyzed for essential metals (Cu, Mn, Fe & Zn) and non-essential metals (Pb) levels seasonally and their bioaccumulation factors. The results revealed that concentrations of the metals differ significantly between the gonads and...

Nearly 1 billion people live without electricity at home. Energy poverty limits their ability to take autonomous actions to improve air circulation and the cooling of their homes. It is therefore important that electricity-access planners explicitly evaluate the current and future air circulation and cooling needs of energy-poor households, in addition to other basic energy needs. To address this issue, we combine climate, socio-economic, demographic and satellite data with scenario analysis...
