Causes of poor achievement in West African school certificate mathematics examinations in Rivers State secondary schools, Nigeria

Abstract: An investigation into the causes of poor achievement in West African School Certificate Mathematics examinations was conducted in eleven randomly selected secondary schools in Port Harcourt Local Government Area of Rivers State. The results showed among other things that most of the students doing mathematics have very little interest in the subject. It also shows that most of the students prefer other subjects to mathematics, and regard the subject as being difficult. Almost all the students study mathematics because it is compulsory in WASC, and because without studying it they may not gain entry into any of the Nigerian Universities. Only a very small percentage of the teachers who teach mathematics in the schools have a teaching qualification, though almost all of them are graduates. Most of the teachers teaching mathematics in these schools still use the traditional ‘talk and chalk’ method when teaching. The relationship between the students and their mathematics teachers is only fairly cordial. Few ...

Green and Eco-Benign Corrosion Inhibition Agents: Alternatives and Options to Chemical Based Toxic Corrosion Inhibitors

Abstract: The control of corrosion of metal and its alloy dissolution in environments that induce corrosion has been reviewed showing successes recorded in the search for alternative inhibitors that would replace toxic and expensive inhibitors that in some instances require rigorous process of synthesis Studies show that organic compounds, drugs, polymers and extracts from plant have been used It also shows that in an effort to improve the efficiency of the developed inhibitors quite a number of them have been synergized with halide ions and surfactants The mode of adsorption mechanism for majority of the tested inhibitor alternatives is also highlighted

Effect of germination on bread-making properties of wheat-fluted pumpkin (Telfairia occidentalis) seed flour blends

Abstract: Rheological and bread-making properties of blends containing 0-25% defatted flours from ungerminated and germinated fluted pumpkin (Telfairia occidentalis Hook) seed substituted wheat flour blends were investigated Dough rheology was studied using a Chopin alveograph, while bread loaves were prepared from the blends using the straight-dough procedure and evaluated for loaf weight, loaf volume, loaf height and sensory characteristics Up to 10% substitution of wheat flour with ungerminated pumpkin flour produced bread with acceptable crust and crumb color and crumb texture Loaf height and volume, however, decreased significantly (p < 005) when the pumpkin flour level in the bread increased beyond 5% Germination had no effect on dough extensibility, hot increased resistance to extension and mechanical work for dough deformation Addition of flour from germinated pumpkin seeds to wheat flour had a detrimental effect on loaf volume, bread color and texture
