The adsorption and inhibition of Aluminium corrosion in 1.0 M HCl using different concentrations of extracts of Baissea axillaris was investigated at 303 and 323K using weight loss technique. Weight loss and corrosion rate increased with increase in temperature both for the free acid and inhibited solutions, with marked reluctance to increase in both observable in for the presence of the extracts, varying with the extract concentration. Inhibition efficiency increased with increase in the concentration of the extract. The maximum inhibition efficiency of 86.3% was obtained for 10 µg/L extract but decreased to 68.4 % on increasing the temperature from 303 K to 323 K. The adsorption was best described by the Temkin and Langmuir adsorption isotherm from where negative Gibbs free energy change was obtained indicating spontaneous adsorption while negative heat of adsorption was obtained indicating exothermicity. Activation Energy was deduced from the Arrhenius equation while thermodynamic approach yielded the heat of adsorption.

The levels of fatty acids, phospholipids and sterols were determined in the skin and muscle of Alestes macrolepidotus. Results showed crude fat varied from 0.488-5.46 g/100 g; SFA from 16.0-29.5 % of total fatty acids, total unsaturated fatty acids varied from 61.6-80.9 %, PUFA range was 33.1-37.4 % and PUFA/SFA ranged from 1.27-2.07.Skin and muscle had low levels of n-6 fatty acids but high in n-3 fatty acids. Correlation coefficient was significantly and positively high at r = 0.05 in the fatty acids. In the phospholipids, lecithin was highest both inskin and muscle with respective values of 734 and 313 (mg/100 g). The sterol values in the skin varied from81.6-81.7 mg/100 g and muscle was not detected (–) to11.4 (9.89±2.62) mg/100 g. Whilst 100 g skin would provide 3.82 g fatty acids, 100 g muscle would provide 0.342 g fatty acids.

Fortification of yogurt by dietary fibers from different natural sources has been used to improve its health benefits. However, this could lead to change the other quality parameters of the yogurt. Hence, it is necessary to have an idea about the effect of dietary fiber incorporation from different natural sources on the quality attributes of yogurt. This paper reviews the effect of dietary fiber incorporation to yogurt from different natural sources to its quality attributes.

Jasikan College of Education is a college that has been designated to serve as Teacher Education Institution, which trains teachers academically and professionally to teach at the basic school level in the Ghana. Based on this vision, the college runs two major programs i.e. “The General Education Program” and “The Early Childhood Program”. The Early Childhood program is a program that sees to the training of teachers to teach at the lower primary schools in the country such as classes (1-3), and kindergartens (1-2). At these lower primary levels, pupils and teachers are not expected to do arithmetic’s with simple and or programmed calculators in any of the subjects. However, when it comes to arithmetic’s on conversion of S.I units, most teachers and pupils in class three end-up using calculators in arriving at answers / solutions. When this happens most pupils tend not to comprehend the subject. In view of this the researcher designed “The D-Conversion model Solution Calculator” from the Distance conversion model (The D-Conversion model) to help both teachers and pupils arrive at answers very easy to tutors and meaningful to pupils when it comes to conversion of distance. This D-Conversion model Solution Calculator is a tool which helps one to arrive at the same answers that simple and or complex calculators give. The D-Conversion model Solution Calculator on one dimension distance (length) was tested on the 114 second year Early Childhood students of Jasikan College of Education. Its used in this study was (1) to see whether the 2011/ 2012 Early Childhood students will be able to perform some arithmetic’s on conversion of length without the use of calculators and (2) to aid the 2011/2012 Early Childhood students design their own teaching and learning material in teaching conversion to the use of calculators as a teaching and learning material in their out-segment schools and or their posted schools.

On the idea of a theory is the title of a paper written by Andrew Chesterman (2007), a great scholar in the realm of Translation Studies (TS). The paper has been published in the journal of Across languages and Cultures, a leading journal in Translation Studies. There are many concepts in Translation Studies (TS) which have been given different definitions. There is no consistent terminology. One can pay attention to different definitions of the key concepts of “translation”, “equivalence” and “strategy”.

Angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease. Angina is a symptom of a condition called myocardial ischemia. It occurs when the heart muscle (myocardium) doesn't get as much blood (hence as much oxygen) as it needs. This usually happens because one or more of the heart's arteries (coronary blood vessels that supply blood to the heart muscle) is narrowed or blocked. Insufficient blood supply is called ischemia. Major risk factors for angina include cigarette smoking, diabetes, high cholesterol, high blood pressure, sedentary lifestyle and family history of premature heart disease. . This causes the distal part of the heart does not receive any more blood and individuals will develop chest pain. Initially when the coronary disease is mild the angina will occur during exercise, eating heavy meals, extreme heat or stress. As the coronary disease worsens, the angina will come on with minimal work and may even occur at rest. The first approach in the treatment of angina pectoris is to prevent the progression of heart disease. By addressing the known causes of heart disease, such as reducing high cholesterol levels, controlling high blood pressure, stopping smoking, losing weight, exercising and eating a “heart-healthy” diet, the symptoms can be reduced. Most people can live a productive life if they make the necessary lifestyle changes. By following medical advice, taking doctor-prescribed medication, maintaining a good, physical condition and eating well, angina can be controlled. There are also natural alternatives to conventional medicine such as herbal and homeopathic remedies useful in controlling angina without the harsh side effects associated with prescription drugs. Herbal and homeopathic remedies are safe and gentle to use, while at the same time addressing the underlying causes of the condition.

The test on  in vitro antagonistic acitivity in dual culture showed significance reduction in the radical growth of Rhizoctonia bataticola and Sclerotinia sclerotiorum  over control (90 mm colony diameter) and in the field trial study seed treatment with strains of Pseudomonas fluorescence significantly reduced the disease incidence of dry root rot and stem rot  in all  treatments  in comparison to uninoculated control, however Pseudomonas fluorescence strains BHUPf₄ was found more effective in mycelial growth reduction as well as disease reduction of both fungal pathogen namely Rhizoctonia bataticola and Sclerotinia sclerotiorum this is followed by strains BHUP₅, BHUP₆ and BHUPsb.

A matroid is a set with an independent structure defined on it. A matroid abstracts and generalizes the notion of linear independence in vector spaces and independence in graphs. Matroids unite the concepts of graph theory, linear algebra, projective geometry, transversal theory, and combinatorial optimization. Applications of matroids involve different areas such as combinatorial optimization, network theory, coding theory and many other areas. Matroids can be found in projective geometry; the fano plane of order 2 gives rise to a matroid. An important application of matroids in optimization involves the greedy algorithm. Kruskal’s algorithm for ?nding a minimal spanning tree which is an example of the greedy algorithm can be used to understand how matroids can be involved in the greedy algorithm. Consider a network of vertices with weighted links between the vertices. Our goal is to ?nd a collection of links that connect all vertices using the smallest weight. That is a spanning tree with minimal weights. Kruskal’s algorithm can be generalized to a matroid by taking a matroid M and a function w:M?R which assigns weights to each element. The goal is to ?nd the basis B of M such that ?w(x) where x?B is minimized. The greedy algorithm is a characterization of the matroid. Matroids are the structures in which the greedy algorithm works successfully

The aim of this current article is to illustrate in detail Armenian relativistic formulas and compare them with Lorentz relativistic formulas so that readers can easily differentiate these two theories and visualize how general and rich our Armenian Theory of Special Relativity really is with a spectacular build in asymmetry. Then we are going behind this comparison and illustrating that build in asymmetry inside Armenian Theory of Special Relativity is reincarnating the aether as a universal reference medium, which is not contrary to relativity theory. We mathematically prove the existence of aether and we show how to extract infinite energy from the time-space or sub-atomic aether medium. Our theory explains all these facts and peacefully brings together followers of absolute aether theory, relativistic aether theory or followers of dark matter theory. We also mention that the absolute aether medium has a very complex geometric character, which has never been seen before. We are explaining why NASA's earlier "BPP" and DARPA's "Casimir Effect Enhancement" programs failed. We are also stating that the time is right to reopen NASA's BPP program and fuel the spacecrafts using the everywhere existing aether asymmetric momentum force.
