Objectives: The study was done to determine the extent of coronal tissue loss of endodontically treated teeth. Results: 176 teeth of 168 patients that completed endodontic treatment to obturation stage were evaluated for coronal tissue loss. The teeth included fifty-five anterior teeth (31.3%), seventy-three premolars (41.5%) and forty-eight molars (27.3%). Majority (43.2%) of the root filled teeth evaluated for coronal damage had minimal coronal tissue damage, followed by teeth with...

The most significant problem of African American students in America’s schools is the wide achievement gap in mathematics. Achievement of minority students lags behind that of Whites and non-minority students. This research will show facts as they exist today in America’s schools relating to the achievement gap dilemma. It is well known and documented that children of color are underrepresented in gifted programs. On national assessments in mathematics, Black students’ performance continues...

University education came to Nigeria for the first time when the first university college was established at Ibadan in 1948. Since then there has been rapid growth and expansion of universities across the country. The expansion of universities has created management problems in enrolment, staffing, funding, material/facilities, etc. This study is designed to examine the extent and gravity of these problems. The study emphasizes the need to increase the number of universities to satisfy the...

Vitamin A (VA) deficiency is widespread in sub-Saharan Africa and school-age children are a vulnerable group. In Burkina Faso, the production and consumption of red palm oil (RPO) is being promoted as a food supplement for VA. The objective of the study was to assess the impact on serum retinol of adding RPO to school lunch in two test zones of Burkina Faso.Over one school year, 15 ml RPO was added to individual meals 3 times a week in selected primary schools in two sites. Serum retinol was...

Since William E. B. Dubois1 wrote The Negro in 1915, Black Folk: Then and Now in 1939, as well as The World and Africa in 1946, scientific facts of the Leakeys and other2 have demonstrated that African is th actual cradle of Homo sapiens. According to Cheikh Anta Diop, (1923-1986), the foremost Sengalese Africanist, the Nile Valley of Egypt, not Greece, was the cradle of Philosophy, and other human sciences, culture and civilization. His first of ten theses which were postulated in his...

This paper takes the position that African language pedagogy should go beyond classroom activity and the space should be enlarged to include the media of mass communication. The paper reiterates the fact that communication is a vehicle for education. The mass media, because of their general accessibility, are said to be veritable tools in popularising the use and learning of African languages that are, presently, being threatened out of existence by the European languages foisted on the...

The public profile of the Brown v. Board of Education decision tends to overshadow the well-established fact that racial disparities in school resources in the South began narrowing 20 years before the Brown decision and that school desegregation did not begin on a large scale in the Deep South until ten years after the Brown decision. We instead view Brown as a highly visible marker of public policy’s mid-century reversal on matters of race. When we examine the labor market outcomes of male...

Climate Change has become the most talked about issue in recent times. The impact of climate change is likely to become more evident in the coming decades. Currently, atmospheric conditions, especially in the dry season, are getting hotter and drier with increased heat waves. Increased demand for air conditioning for space cooling as a result of internal discomfort in buildings is already manifesting. This could put an additional stress on the already over-burdened energy capacity of the...

Whole rock major and trace element abundances in aluminous garnet–spinel websterite, sapphirine-bearing Mg–Al granulite and hibonite-bearing Ca–Al granulite xenoliths from the Chyulu Hills volcanic field, Kenya, suggest that the samples represent a meta-igneous suite linked by fractionation. The incompatible major element contents increase from the websterites to the Mg–Al granulites and further to the Ca–Al granulites. High bulk rock Mg#s and very low concentrations of most incompatible...

Abstract Background Human mydriatric drug use in non‐human primates (NHPs) has been documented but not quantified and compared for effectiveness. The objective of this study was to determine which drug regimen provided the most effective and consistent mydriatic effect for ophthalmologic examinations and other procedures. Secondary objectives were to determine average time to maximum dilation and whether species differences existed. Methods Twelve rhesus and 12 African green monkeys were...
