Noise-induced hearing loss (NIHL) is viewed as the noise exposure levels related to an eight-hour working day (LEx, 8h) exceeding the occupational exposure limit (OEL) of 85dB(A), which can irreversibly damage sensory hair cells of the cochlea. NIHL refers to the sounds at some frequencies that are more hazardous than other frequencies. The use of A-weighted sound levels cancel these effects so that two sounds with the same dB (A) level have approximately the same hazard.

We investigated the effect of satellite classes as a component of blended learning, to enhance student performance of the Business Management I and Management I students at an open and distance-learning university. We discuss the evolution of distance education, the interactivities promoted by open and distance learning and the concept of blended learning. The main question addressed is whether student performance in two first-year modules, Business Management I and Management I, is affected...

Although neighborhood disadvantage has been linked to the development of cardiovascular disease, the mechanism through which living in impoverished neighborhoods is associated with poor cardiovascular health is not well understood. Additionally, it is not clear whether individual socioeconomic status (SES) interacts with neighborhood factors to influence cardiovascular outcomes. Using multilevel modeling, we examined the interaction between neighborhood poverty and individual SES on pressor...

Mineral and geochemical investigations were carried out on soil samples and fresh rock (trachytes) from two selected soil profiles (TM profile on leptic aluandic soils and TL profile on thapto aluandic-ferralsols) from Mount Bambouto to better understand geochemical processes and mineral paragenesis involved in the development of soils in this environment. In TM profile, the hydrated halloysites and goethite occur in the weathered saprolite boulders of BC horizon while dehydrated halloysite,...

This article examines how the South African Committee for Higher Education used the resources of print culture to design forms of writing and delivery systems that provided students and post-literate adults in the anti-apartheid struggle of the 1980s with the means to recognize and represent themselves as rhetorical agents, for whom reading and writing were tools of deliberation and social action to participate in building a non-racial political future.

The neonatal brain is particularly vulnerable to imbalances in redox homeostasis because of rapid growth and immature antioxidant systems. Vitamin C has been shown to have a key function in the brain, and during states of deficiency it is able to retain higher concentrations of vitamin C than other organs. However, because neurons maintain one of the highest intracellular concentrations of vitamin C in the organism, the brain may still be more sensitive to deficiency despite these preventive...

The purpose of this study was to describe the attitude of University of Nigeria pharmacy students towards pharmaceutical care.A survey of pharmacy students in their second to fifth year was conducted. A modified 13-item standard Pharmaceutical Care Attitudes Survey (PCAS) was used for the study.

Recently, politics of education in Nigeria have shifted from urban to rural literacy, which led to the development of programmes such as the nomadic women’s adult education programme. The primary objective of this study was to evaluate the efficacy of the programme’s implementation strategies, and the extent to which the health educational objectives have been achieved and practised by the Fulani pastoral women. A qualitative narrative research design was used to collect social data from the...

Today, Egypt suffers from deterioration of education quality as a result of deficient learning spaces, insufficient governmental expenditure and funding, and lack of proper research in education developmental strategies. Additionally, 21st century learning requires innovative spaces that connect school, home, and community. Therefore, new learning spaces should increase flexibility, support hands-on and outside-class learning activities in order to motivate learners. Furthermore, they...

Using methods of naturalistic inquiry, this study examines preservice teachers' conflict with classroom management strategies used in a predominantly African-American urban elementary school. It highlights the theory/practice dilemma, focusing on the tensions between the democratic strategies taught in university classes and the more authoritarian strategies actually found in the urban classrooms. The use of power and caring, evident in the interactions of the teachers with their students,...

The main argument posed in the paper is that attitudes are an important factor in the way men and women are disproportionately participate and are affected by access to technical training and work based learning opportunities. The camp of transformation and critical feminist thinkers who view...
