When I was still a teenager, in my fourteens, my father called me to his watch-making workshop, sat me down on the top of his lap swinging to the left and to the right along with the tick-tack’s sound of the grandfather clock’s pendulum coming from the furthest corner of the room.

Inhibition of copper corrosion by some thiazolidine derivatives in 1 M HNO3 was inspected by" WL (weight loss),(EIS) electrochemical impedance spectroscopy, (EFM) electrochemical frequency modulation and potentiodynamic polarization measurements". The inhibition effectiveness expanded by the expansion in the concentration of inhibitor and deceased when temperature increased. It is clearly that these mixes work as mixed type inhibitors and that was proven by Potentiodynamic polarization study. These inhibitors whose adsorption was found to comply Langmuir adsorption isotherm. When a number of unique strategies were in great understanding, the outcomes resulted. Relationships of quantum structure-movement have been utilized to examine the molecular structure impact on the inhibitors efficiency. The surface morphology of copper specimen was explored by scanning electron microscopy (SEM).

This work sets out to interrogate the phonological processes involved in the formation of multisyllabic nouns in the Izii and Ezaa dialects of the Igbo language using the autosegmental method of analysis. The data were gathered using the personal interview method. Six respondents, three males and three females were sampled and one hundred and fifty words randomly selected from the Ibadan 400 Word List (as outlined in Udoh (2004) were used and the interview was recorded electronically. In the findings, the phonological processes of deletion, elision and insertion were mainly used while the results of the processes were inflectional as no change of word class was recorded. However, some of the processes produced contour tones, closed syllables as well as consonant clusters especially in Ezaa dialect portraying unusual phonological features when compared with other dialects of the Igbo language.

Clean water is absolutely essential for healthy living. Adequate supply of clean drinking water is a basic need for all human being on the earth. Yet it has been observed millions of people worldwide are deprived of this. Freshwater resources all over the world are threatened not only by over exploitation and poor management but also by ecological degradation. The main source of fresh water pollution can be attributed to discharge of untreated waste, dumping of industrial effluent, and runoff from agricultural field. Industrial growth, urbanization and increasing use of synthetic organic substances have serious and adverse impact on fresh water bodies. Developed & developing countries suffer from problems of chemical discharge into the water sources mainly ground water1, and agricultural runoff in water sources. Polluted water causes problem in health. Nowadays heavy metal pollution2 is a serious and most dangerous threat3 to human being which can be prevented by taking some measures. Many areas of ground water and surface water are now contaminated with Heavy metals that have in adverse effect on Health. This study aims to detect the possibilities of ground water quality deterioration due to improper waste dumping with special reference to heavy metal pollution. Since it is well established fact that the heavy metal ions are potentially toxic4,5 to human health and could be quite detrimental for human life.

Over the years, horticulture emerged as a crucial and emerging part of agriculture, offering a wide range of choices to the farmers for crop diversification. It also provides sufficient opportunities for sustaining large number of agro industries which generate substantial employment opportunities. In India, there are a number of major fruits like banana, mango, citrus, papaya, apple, litchi, pineapple and many others. If we talk about the area covered under fruits we have found out that there is almost 100% increase in the area and 121% increase in production. Specifically speaking Apple is by far the most important fruit. Today, India ranks second in the world in terms of area under apple cultivation. With 2.5 million hectares under cultivation, India produces more than 1.4 million tonnes of apples every year (FAO). Among the fruit grown in India, apple has the third largest area under cultivation, after banana and mango. Being somewhat hard, the potential post-harvest losses in transportation are relatively low and shelf life compared to other tropical fruit grown in India is comparatively large.

The Coronary artery development is a delicate process that includes a complex interaction among the pericardium and the myocardium which leads to involving of multiple cellular pathways. There has been a growing engrossment in the study of the coronary artery development. These leads to identify some of the important causes of anomalous coronary development.There are different kinds of anomalous coronary arteries, having variable risk in myocardial ischemia, malignant arrhythmias, and sudden cardiac death also. A good understanding of this process could help us insharing new avenues in the treatment of clinically relevant anomalous coronary arteries.

Generally, Gonadal Dysgenesis is a condition which can be characterized by the underdeveloped or imperfect formation of the gonads. This occurs either due to the absence of the sex determining region of the Y chromosome (SRY) gene and therefore differentiation of the indifferent gonad would not occur. Hence, the other activities such as development of testes, production of its specific hormones and the formation of the other internal reproductive organs that needs those hormones in order to develop would be under developed.

WHO defines Overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health. A crude population measure of obesity is the body mass index (BMI), a person’s weight (in kilograms) divided by the square of his or her height (in metres). A person with a BMI of 30 or more is generally considered obese. A person with a BMI equal to or more than 25 is considered overweight.

The Eastern Dahomey Basin is a rift basin located in the Southwestern part of Nigeria with formations spanning from the Cretaceous to Tertiary ages which are well defined in their lithology types ranging from sand, silt, carbonates, and shale. Shale is now considered as a reservoir rock in the unconventional petroleum system unlike its previous characterisation as only a source rock and/or seal in the conventional petroleum play. The hydrocarbon field operators in the Dahomey basin have reported higher percentage of gas production up to 20% LPG and 52% gas and also identified the syn-rift to contain light oil and condensate-rich gas. The increasing demand of natural gas as a cleaner energy compared to other fossil fuels and the several commercialization strategies of the Federal Government of Nigeria has necessitated the exploration possibility of more gas, even unconventional gas. This paper reviewed the geological and geochemical properties of the Dahomey basin from previous authors and selected some producing plays in the USA as possible analogues for its shale gas potential.

Institutional ranking has become a competitive trend in promoting quality education across the globe. This ranking system facilitates fare competition in terms of teaching-learning and investment among its various stakeholders namely students, teachers, parents and investors with special focus on academic excellence leading towards lucrative placement in the corporate world. The college and university ranking practice mostly conducted by leading magazines, newspaper, websites, government and academics has been primarily observed since long in the western world especially in the USA and Europe. However it has not remained confined within that territory only; rather it has expanded its boundaries and reached all corners of the world including South- East Asia as well. This article is a critical review of the existing ranking systems available worldwide with special focus on the USA and European college and university ranking practices. Thus this paper has critically reviewed various ranking systems along with their general and specific criteria such as admission acceptance rate, average alumni donation rate, average graduation rate and performance, class size, expenditure per student, faculty compensation rate, faculty with PhD or terminal degree, lucrative placements of alumni, peer assessment, SAT/ACT score and Student-teacher ratio and many more. Finally this study has highlighted many important issues relevant in our context some of which are not feasible to adopt in this very socio-economic as well as cultural context of our country. However the study has been found very significant in the context of our education system to promote fare competition among the relevant stakeholders and ensure quality education both in public and private universities leading towards pertinent placement in the Government and industrial sector.
