Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...

background: qeshm (26.75n, 55.82e), iran, is 1500 km² island in the strait of hormuz. qeshm is a free trade zone, acting as an important channel for international commerce, and has been the site of much recent development. there is potential risk of stinging ant attacks for residents and visitors that may occur in the island. the aims of this study were to find out the fauna, dispersion, and so...

T his paper ascertains the extent of mispricing in equity portfolios, mispricing-divestment relation, and the role of African equities as risk diversification strategies during commodity market turbulence. Following Baur and Lucey (2010), one identifies an arbitrary commodity market crisis to be 1%, 5%, and 10% declining moments in returns. However, their approach is extended by usin...

Introduction: Chronic kidney disease (CKD) is known to be associated with deterioration of mental health. However, it is clear that this link is over and beyond the effects of socio-economic factors and other medical conditions. This study had two aims: 1) to compare the association between CKD and general anxiety disorder (GAD) among the two major ethnic groups of American Bla...

six red sokoto (rs) and west african dwarf (wad) does, raised intensively in livestock farm of michael okpara university were evaluated for milk yield and composition in a ten-week study. the animals in their first parity were fed cut-and-carry forages in a cafeteria arrangement between 07:00-08:00 h daily and also were allowed access to concentrate supplementation by 14:00 h. the forage consis...

background this quantitative explanatory study was designed to explain the relationship between hiv/aids risk-taking behaviors among african american women and their knowledge surrounding hiv/aids. more specifically, the research considers whether knowledge alone was sufficient to alter african-american women’s risk-taking behaviors regarding hiv/aids. objectives this study was designed to inve...

this study evaluated the effects of 0.25% activated charcoal added to sesame seed meal (ssm) in partial replacement of soybean meal (sbm) of juvenile clarias gariepinus diet on growth and haematological parameters for 70 day experimental period. six experimental diets were formulated as: control diet 1 (100% ssm without activated charcoal), control diet 2 (100% ssm plus 0.25% activated charcoal...

it has previously been demonstrated that circulating levels of leptin show ethnic differences when controlled for the confounding influence of adiposity. this study examined leptin levels in non-obese and obese subjects with type 2 diabetes of african versus caucasian origin. materials and methods non-obese and obese subjects with type 2 diabetes of either african origin living in dar es salaam...
