Effectiveness of Appraisal System on employee’s performance
This study focuses on, how much an appraisal system is effective in an organization and what would be its impact on employees’ performance. This paper focuses on different aspects of an appraisal system. Today organizati1ons are using different methods or combination of those methods. Rewards and incentives are also given on the basis of employees’ performance. Now the study examines what the effect of appraisal system on employees’ performance is. Whether it increases their performance, decreases their motivation or it has neutral effect. This paper concludes that in some organizations most of the employees feel that appraisal system in their organizations/universities is satisfactory. Many employees also want to have a right to appeal against the appraisal system. Most of the employees agreed that this system is not just wastage of time and money. Employees in particular universities want to be appraised by committee rather than boss. Many employees also agreed that if the appraisal system in their organization seems to be excellent one, they will feel motivated. They also agreed that their organizations are applying non discriminatory practices regarding males and females. This paper concludes that employees in particular universities are satisfied with the appraisal system and its practices and no gender discrimination is being adopted. To make appraisal system more effective, Using only one type of appraisal system, objective criteria, ethical aspects, fairness, following the one’s own cultural practices, privacy in appraisal process and level of trust between the employee and supervisor and behavior oriented criteria are further suggested.

Security Enhanced RSA Public Encryption System
In our paper , we have suggested a variant of the RSA public cryptosystem, it is more effecient than the traditional RSA algorithm which uses the Euler’s Totient Function .The discussed RSA variant is very much similar to the traditional RSA. It also is a block cipher like the traditional one but it uses a different Ø(n) function. In the suggested scheme the range of Ø(n) is so high that it increases the security manifold. This makes cryptanalysis very difficult. Methods like brute force attack will fail as the range is very high and such attacks consume a lot of time. We represent Ø(n) as f(n,h) where n can be a Positive Integer(Z). As the value of h keeps increasing the range of values of Ø (n) also keeps increasing exponentially which in turn increases the security exponentially. This is the reason why the proposed scheme can be assumed to be more efficient, reliable and scalable.

Fund mobilization role of cooperative thrift and credit societies in Nigeria
The study looks into the fund mobilization role of cooperative thrift and credit societies in Nigeria .The cooperative thrift and credit society of Ajayi Crowther University Oyo State of Nigeria was used as a case study. Primary data were coalated from the workers of the university serving as the respondents through the questionnaire instrument. The responses were analysed with the use of simple percentages. Two hypotheses were also tested to confirm the analysis. It was discovered that every member of staff consulted belong to one or two cooperative societies due majorly to the easier access of getting loan from the societies than from the banks. The loans given by the societies were also derivable from the savings contributions from members. It can therefore be concluded that cooperative thrift and credit societies in Nigeria are good in mobilizing funds from the surplus unit (the savers) to the deficit unit (the borrowers), the activity that has led to economic development of the co-operators and their societies at large. It is therefore good for government to give more recognition to the societies and should be extending grants and loans to them to boost their activities. This would help in filling the financial gap which has been existing within the whole range of financial intermediation process in the country.

Molecular interaction studies of antibiotic with unsaturated fatty acid
The Dilute solution viscometric (DSV) technique is employed to find the molecular interactions between the non-Newtonian Doxycycline hyclate and the essential unsaturated fatty acid, Ricinoleic acid in the common solvent Ethyl methyl ketone. The viscometric parameters as improved by chee and Sun et. al., identifies the molecular interactions at physiological temperatures. The conformity of interaction is attempted by the ultrasonic velocity; and the related acoustical parameters at temperatures 303, 310 and 313K. The behaviour of these parameters explains the molecular interactions on the basis of solute-solute and solute-solvent interactions.

Electronic Banking in Nigeria: Challenges and Prospects
Electronic banking (e-banking) system has become an important practice among commercial banks in Nigeria. The introduction of this banking system has improved banking efficiency in rendering services to customers and the public. However the gains of e-banking has been associated with some hinderances ranging from internet failure to arbitrary withdrawal of money by customers which negates the cashless policy being heralded by the Central Bank of Nigeria (CBN). It was in line with this that the study aims at examining the challenges facing this banking system and the prospects accruable to its adoption. Among the various suggestions made in this study- to benefit maximally from e-banking- include provision of enabling environment that can guarantee safety of lives and cash deposits of customers, provision of an interrupted power supply and internet service in order to enjoy efficient services from the banks. Lastly, enforceable e-banking regulations should be put in place to back up the cashless policy already initiated by the CBN. This will go a long way to reduce money laundering and reckless withdrawal of cash and thereby boosting capital formation and investment in the economy.
