Locally produced foreign varieties of Magnifera indica (Keith and Kent varieties) were sampled and purchased from farms and markets within the Yilo and Lower Manya Krobo districts and analyzed for pesticide residues by gas chromatography equipped with an Electron Capture Detector (GC-ECD). In all, 80 samples were extracted and analyzed for mainly organochlorine residues (?-HCH, ?-HCH, aldrin, dieldrin, heptachlor, ?-chlordane, endosulfan s, p, p’-DDE etc.) and synthetic pyrethroid residues (allethrin, bifenthrin, fenpropathrin, permethrin, cyfluthrin etc.). Analysis indicates that about 88% of the mangoes sampled from the farms and markets contained one or more of these pesticide residues. The data also revealed that about 6.2% of the samples analyzed contained organochlorine pesticide residues of ?-HCH (0.013mg/kg and 0.038mg/kg); ?-HCH [0.014mg/k]; methoxychlor [0.027mg/kg] above maximum residue limits. Synthetic pyrethroid residues of cyfluthrin [0.078mg/kg] and fenvalerate [0.025mg/kg] were also found above their respective maximum residue limits. However, 78.2% of detected pesticide residues were below the Maximum Residue Limits. Nonetheless, the continuous consumption of these fruits with even the modest pesticide levels can result in accumulation that could result in deadly chronic effects.

Previous perspectives have indicated that self disclosure is an indication of intimate relationships. The high incidence of broken homes, non working and unhealthy interpersonal relationships, and multiple partners menace among adolescents around the world, in the recent times require that concerted efforts be geared towards an understanding of the root causes of this problem. This is particularly so because children of such broken homes are often mal-adjusted and constitute problems to the society. This study therefore examined the effects of sexual self esteem and sexual self assertiveness on sexual self disclosure among heterosexual adolescents in Nigeria. A sample of 172 Nigeria undergraduate students randomly selected from among the undergraduate students of the University of Ado Ekiti, Nigeria; whose mean age is 28.2 was used. Four hypotheses were tested and it was found out that sexual self esteem is not a significant factor affecting sexual self disclosure [F(1) 164 = .311, P>.05 ]. It was also revealed that sexual self assertiveness is a significant factor affecting sexual self disclosure [F(1) 164 = 16.594, P<.05]. And it was found out that there is no significant interaction effect of sexual self esteem and sexual self assertiveness on sexual self disclosure among heterosexual adolescents in Nigeria [F(1) 164 =.456, P>.05]. No significant relationship was also found between sexual self esteem and sexual self assertiveness [r(168) =.060, P>.01]. The findings were discussed in light of available literature and it was recommended that sexuality education should be included in schools curricular to enhance the acquisition of sexual life skills for the communication of sex related issues and boost a healthy sexual and interpersonal relationships.

Microencapsulation is a process by which solid, liquid or even gaseous particles are coated with a continuous film of polymeric material, having a diameter in range of 1 to 1000 ?m and are widely used as drug carriers. The purpose of writing this review on microencapsulation by solvent evaporation technique was to compile the recent literature with special focus on solvent evaporation technique for microencapsulation of pharmaceuticals that have recently become leading investigated technologies in the field of drug delivery development. In order to understand the microencapsulation by solvent evaporation technique, the basics was summarized. Afterwards, we have reviewed various solvent evaporation techniques designed and developed until now. Finally, various potential factors influencing microencapsulation by solvent evaporation technique were covered in detail.

According to Freud the Oedipus Complex, manifests itself in the child around the age of five. It derives from the boy’s unconscious rivalry with the father for the love of his mother. Freud referred to the whole complex of feelings by the word "oedipal," naming the complex after the Greek tragic hero Oedipus, who unwittingly killed his father and married his mother. Fixation, according to Freud, is a source of disharmony of development when childish forms of libido persist. If there is frustration in the gratification of these forms of libido representing the vital needs in childhood, the individual’s development may be arrested or fixated and abnormalities may appear in the adult personality. These theories have gradually opened up a new awareness to understand and interpret certain plays of Eugene O’Neill. This paper intends to show how O’Neill presents the powerful motive of Oedipus and Electra complex, the incestuous relationship and fixation among characters in Desire Under the Elms, Strange Interlude, Dynamo, Mourning Becomes Electra.

Various phenomena occur in Air dielectric when a voltage is applied. When low voltage is applied, small current flows between the electrodes and the insulation retains its electrical properties. If the applied voltage is large, the current flowing through the insulation increases very sharply and an electrical breakdown occur. A strongly conducting spark formed during breakdown, practically produces a short circuit between the electrodes. The maximum voltage applied to the insulation at the moment of breakdown is called the breakdown voltage. For a uniform gap, the effect of humidity on the breakdown voltage is negligible. For non-uniform gaps such as rod-sphere, point-sphere like gaps the influence of humidity is found to be of significant. A correction procedure recommended by IEC is commonly used for converting the measured voltage or the test voltage from non-standard to standard reference atmosphere. So the result in analysis is then corrected into the standard reference conditions [in STP].

Present study was design to measure the students’ perception and expectation from the teachers of higher education. Population of the study comprised of university students who dropped out from university or who got less than 60% marks. Students were contacted at university campuses and hostels in the vicinity of Rawalpindi/Islamabad. A purposive sample of 86 male and female students was collected from these two afore mentioned levels of the population. Through this study various important role of teachers’ behaviour unravel and findings of the study suggest that teachers behaviour is important because it can favourably or adversely affect the student’s attitude towards learning. In the process of teaching learning students have expectations from their teachers, both professional and behavioural, negative behavioural traits of the teachers behaviour can impaired teacher students relationship and also disgrace teachers image in the eyes of their students. Findings of the study will be helpful for teachers to evaluate and re-examine their behaviour in the light of their students’ expectations.

Conversion within quantities of same units and between quantities of different units is a thorny subject to students of Jasikan College of Education (Butterfield, Sutherland & Molyneux-Hodgson, 2000) and its treatment by tutors sometimes becomes very difficult such that most tutors resort to handling the subject theoretically/ abstractly. When this happens most students seemed not to comprehend the subject. In view of this, the DTML-Conversion model (i.e. D-Conversion model, T-Conversion model, M-Conversion model and the L-Conversion model) was designed. The DTML-Conversion Model is a model that has been designed by the researcher to make the teaching of conversion in measurement very easy to tutors and meaningful to students. The DTML-Conversion Model was tested on first year students of Jasikan College of Education. The researcher tested the DTML-Conversion model on 150 first year students in Jasikan College of Education by first teaching conversion using the traditional method which is the Conversion-factor for distance, time, mass and litre for a period of one month. A test was administered, collected and recorded, after which the DTML-Conversion model was introduced with similar test items. Comparison of the two test results showed that, students seemed to comprehend conversion in measurement with the DTML-Conversion model to the conversion-factor method.

The growing trend tendency of web-based business world, emphasized on existence of an important and complementary component such as electronic banking as an undeniable necessity .In recent decades with development of communication and information tools, the volume of e-commerce significantly increased Such that between 2002 and 2006 on average each year 50% has added to the volume of trade exchange through electronic contexts. And its amount from 2,293 billion dollars in 2002 has reached to over 12,837 billion dollars in 2006. Given the widespread impact of electronic commerce and global markets dominance, it is necessary that the tools and contexts of transfer and exchange of money to keep pace with appropriate and desirable rate to the growth of e-commerce development. Adequacy of international Capital banks introduces the major risks associated with electronic banking as follows: strategic risk, credit risk, operational risk, liquidity risk, market risk and credit risk (reputation and history).One of the main identified risks in this field is that, All financial institutions Given the characteristics of the environment in which they operate And their activity amount are faced with operational risk that should be controlled As much as possible and determine the needed capital to manage it. Our main goal in this study is to identify operational risk factors in the electronic banking of Keshawarzi Bank. We first seek to identify risk factors that lead to this, so by control and reduction of impact of these factors the severity of this risk type is reduced and to bring about better management

Different from other soda ash plants based on Solvay Process in the world, Mersin Soda plant applies a particular process in order to decrease the chloride concentration of the solid waste. The purpose of the current study is to investigate utilization of this solid waste with low chloride content in possible industrial applications. It is determined that using solid waste as a mineral additive in some of the cements produced in Mersin-Adana region, slightly reduces consistency of mortar and shortens setting time. However consistency and setting time of the samples including solid waste can be increased to the levels of the reference sample by using 0.05% of retarding admixture. It is observed that compressive strength of samples with 5% waste is similar to the reference sample. As a result, it has been found that 5 percent solid waste can be used in the cement as a minor constitute.
