This paper re-examines the evidence for cointegration between international stock prices. It applies Johansen’s maximum likelihood (ML) cointegration method Var and impulse response stock price of Nigeria, the United Kingdom, Morocco, South Africa, Tunisia and the United States, with monthly data covering the period of 01/02/2004-01/07/2016. it finds at most one cointegrating vector from the developed market to emerging market. The results show that no bivariate cointegration exists between the Nigeria and any of the stock markets being studied, and the multivariate cointegration confirms the result. The findings on dynamic return linkages is that there is no significant returns linkages among the markets, with the exception to UK. Indeed FTSE100 is the most exogenous. Therefore, all markets are not exposed to the same set of risk factors and the risk premia on each factor varies among all markets. The non-existence of a cointegrating relationship between the Nigerian market and the considered stock markets implies that these markets offer potential for pairwise portfolio diversification for a Nigerian portfolio manager

Truancy is deliberate absence from school on the part of learners without the knowledge and consent of parents. The aim of this study to establish the factors that contribute to students’ absenteeism and their effects in secondary schools in Midnapore District of West Bengal. The study examines the factor that contributes to truancy among secondary school learners. The investigate the effect of truancy. Truancy, or the habitual act of being absent from school without permission, is a major issue affecting the overall success of the school in which I am employed. Truancy may be identified differently between districts, states, or governments; however, consecutive unexcused absences from school is the most common and acceptable definition. Lying and stealing are common, but inappropriate, behaviours in school aged children. Lying and stealing are more common in boys than girls, and happen most often in children ages 5 to 8 years. Children from the ages of 6 to 12 understand what lying is and the moral wrongness of this behaviour. However, children may continue to lie in order to test adult rules and limits. The child may admit to telling a lie, but usually he or she has many reasons for having done so. Rules are very important at this age, so cheating becomes less important. Hysteria is undoubtedly the first mental disorder attributable to women, accurately described in the second millennium BC, and Util Freud considered an exclusively female disease. The evolution of these diseases seems to be a factor linked with social “westernization”, and examining under what conditions the symptoms first became common in different societies became a priority for recent studies over risk factor. The study explored teacher’s perceptions of maladjustment problems manifested by pupils in West Bengal Secondary schools using the psycho-social lens to view and interpret the phenomena. The study found that teachers who were not adequately trained to deal with maladjusted pupils did not endeavour to implement any interventions to alleviate them. It also revealed that not all maladjusted pupils cause disciplinary problems for teachers as some of the pupils who are unsocial with drawn, unhappy, depressed, fearful and nervous do attract very little attention to themselves. In examining the causes of pupil maladjustments the study found that these can be traced to some unfulfilled or thwarted psy-cho-social needs. Several symptoms that interfere with the ability to work, sleep, study, eat, and enjoy life. An episode can occur only once in a person’s lifetime, but more often, a person has several episodes.

The kidney transplant is above all a social project, based on a gift of generosity and solidarity. The specific activity of kidney transplantation from a living donor requires close collaboration between clinicians and biologists.Living-donor renal transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, depending on whether a biological relationship exists between the donor and recipient.It’s the interest of this review with in the last part the path of the donor and the recipient for a possible kidney transplant with a donor living in the renal transplant department at the military hospital of Rabat.

FUSARIUM WILT is a common disease exploded in the Eastern region , central region and western region of forests of Nepal as well as in the Himalayan and Sub Himalayan region of India and other Asian countries . 6-8 % loss is estimated in the previously reported, MISHRA (2016) especially eastern zone of Nepal and adjoining area of Bihar, while PAVITRA et. al (2018) reported molecular investigation of genes expression analysis in to contrasting genotypes of banana during FUSARIUM WILT ( Foc1) infection .

Industrial wastewater containing substances that may affect human health and are difficult to degrade is a major health concern, where examples include effluents containing heavy metals. The contamination of receiving water bodies by heavy metals constitutes a major environmental concern as these contaminants are extremely toxic, recalcitrant, and exhibit a tendency to bio-accumulate. Although heavy metals could be removed from industrial wastewater by a range of physicochemical treatment technologies such as precipitation, ion exchange, adsorption, electrochemical processes, and membrane processes; however, regulatory standards are not always sufficient. The objective of this paper is to study the amenability of using the bacterial strain of Bacillus Subtilis isolated from the surface of natural Egyptian phosphate as an alternative for the conventional techniques of treatment. It is found that Zn removal increased from 80% to 93%, while Pb removal varied from 95.55% to 99.34 % by the addition of 10-20 ml of bacterial strain (Cell + Product) in a solution having 50 mg/l Zn2+ and 30 mg/l pb2+ ions. The relative removal capacity for metals was in the order Pb< Zn.

Microorganisms have a tremendous influence on their environment through the transfer of energy, charge, and materials across a complex biotic mineral–solution interface. The bio-modification of mineral surfaces involves the complex action of microorganism on the mineral surface. The manner, in which bacteria affect the surface reactivity and the mechanism of adsorption and accumulation of the primary data in this area are only starting. Bio-Processing involves the selective removal of undesirable mineral constituents from an ore through microbe-mineral interactions in the processes such as selective flotation and flocculation. At the same time, bio-sorption has made a considerable progress in moving from theory to industrial practice as it is not only environmental useful but also more economical than many other processes. The bio-flotation, bio-flocculation and bio-sorption processes concern the mineral response to the bacterium presence, which is essentially interplay between microorganism and the physicochemical properties of the mineral surface, such as the atomic and electronic structures, the net charge/potential, the acid–base properties, and the wettability of the surface. The adhesion of microorganisms to minerals result in alteration of surface chemistry of minerals relevant to beneficiation process due to a consequence of the formation of a biofilm on the surface or bio-catalyzed surface oxidation or reduction products. There is an urgent need for developing basic knowledge that would underpin biotechnological innovations in the natural resource processing technologies that deliver competitive solutions.

World population growth and increasing needs to various industries have led to the accumulation of a wide variety of contaminants in the environment and natural resources. The use of synthetic dyes is increasing in many areas. More than 10,000 chemically different dyes are being manufactured. Synthetic dyes have been widely used in many industries such as textile, tannery, food, pharmaceutical, pulp and paper, paint, plastics, electroplating, and cosmetics industries.The effluent discharge from these industries has destructive effects on the environment and human health; reducing sunlight penetration and gas solubility in aqueous ecosystems and mutagenic and carcinogenic effects in living organisms. Interest in the pollution potential of textile dyes has been primarily prompted by concern over their possible toxicity and carcinogenicity. Even though physico-chemical methods are effective in dye removal, problems such as the overall cost, regeneration, secondary pollutants, limited versatility, interactions with other wastewater constituents, and residual sludge generation limit their usage. As an alternative, biological treatments are a relatively inexpensive way to remove dyes from wastewater. The use of biological methods such as bioaccumulation and biosorption through bioflocculation technique is suitable for the removal of such dyes from wastewaters. In this study, bacterial strain of Bacillus subtilis has been used for the removal of methyl violet dye from an Egyptian textile effluent. More than 98 % removal is achieved through application of bioflocculation technique. Complete characterization for the textile effluent before and after treatment with bacterial strain has been done including TSS, TDS and turbidity. At the same time, physicochemical characterization of Bacillus subtilis bacterial strain was studied.

This study examined the impact oil price volatility and selected macroeconomic indicators on stock return Nigeria for the period of 2000 to 2015 using Exponential Generalized Autoregressive conditional Heteroscedasticity (EGARCH) model for the volatility Error correction model for long and short dynamics. The results are in three folds: First, the results revealed that oil price volatility has a significant negative impact on stock returns in Nigeria. Second, the results also revealed that there were leverage and volatility persistence in the Nigeria Stock Market. Third, the study confirms co-movement between oil price shock and equity returns in Nigeria. The study therefore recommends that the government should monitor developments in the world crude oil market with a view to diversifying the economy away from crude oil dependence to minimize the consequences of oil shocks on the stock market and the economy at large.

Head teacher is a vital part of any school. A school works as an organization in which Head teacher, teachers and students play their role for its effective performance. Head teacher is responsible for designing the whole framework of school and implementing the educational plan to achieve the set goals. Head teacher and teacher relationship is an effective part of school administration. It does affect the effectiveness of school management and its performance. In this way, it also affects the results of the institutions. The good performance of school shows how much effective Head teacher and teacher relationship exists in school. In order to achieve the objectives of the study, a five-point scale was developed. It consisted of twenty-five statements for Head teachers as well as teachers of secondary schools. For each statement in the questionnaire, five options were given which were strongly disagree, disagree, neutral, agree and strongly agree. The respondents were asked to tick the one option among the given five according to their free will. The questionnaire was validated and pilot tested. The questionnaire was administered to the sample and responses were collected. The data collected through questionnaire was tabulated, analyzed and interpreted. The results of the study show that different school’s head teachers adopt different type of strategies in the same situation but their main aim is to run the system of school smoothly. They effectively play their role in motivating and facilitating the teachers for effective functioning of school.

We report in this study the cases of epilepsy observed in the onchocerciasis focus of the city of Inga in the Democratic Republic of Congo. The aim of this study is to contribute to the search for a possible epilepsy-onchocerciasis relationship in the city of Inga. The average age of our patients is 39, 12 ± 15.71 years with a male predominance (sex ratio = 2, 62). Fishermen are the most affected by onchocerciasis with 44.85%. The length of stay of patients in the city of Inga is 24, 71 ± 9.5 years. The exsangual cutaneous biopsy was positive in 58 people out of 100, ie 58%. The mean parasitic load is 4.65 ± 2.6 microfilariae per biopsy. The presence of onchocerciasis in the city of Inga does not seem to be a determining factor in the occurrence of epilepsy: in our study the association of epilepsy and onchocerciasis has not been demonstrated (p = 0.075). Onchocerciasis could be, due to insomnia and the state of hyperexcitability that it causes, a factor favoring the onset of epileptic seizures and not a cause of epilepsy.
