Abstract This paper focuses on admission policies for higher education in Nigeria: achievements and challenges. It was predicated on the determination of the achievements and challenges of the practice of existing admission policies for improved access and equity in higher education in a heterogeneous Nigeria. A lot of achievements as well as challenges were discerned to be associated with the admission policies. It was concluded that these policies are measures to achieve equal higher educational opportunity, which does not mean sameness or uniformity, but equal treatment of a heterogeneous country. Hence, the practice is supported, but should be based on the economic principle of positive discrimination.

This article, through a qualitative and quantitative analysis, focuses on strategies that CEMEX has carried out to determine how they influence their dominance index or market power. The qualitative analysis is based on mergers and acquisitions; meanwhile, quantitative analysis is performed by means of calculations Herfindahl Hirschman Index and the Index of Dominance. Currently Cementos Mexicanos is the industry leader in building's materials with global presence as it produces markets and distributes cement in approximately 50 countries, maintaining business relationships with approximately 108 nations. Its main strategies are based on the expansion and acquisition of companies in the cement industry.

A very well known ancient fruit whose therapeutic qualities have rebounded and echoed throughout the millennia named as Punica granatum (belongs to family Punicaceae) also commonly known as Pomegranate, Anar or Dalim in North India. Plant based formulations have been used since ancient times and playing role as a remedial agent against various human and animal diseases. Therefore, in the systems of Allopathic, Ayurvedic, Homeopathic and Unani systems, much energy has been devoted to the treatment of disease and enhancement of physical and mental health. The interest in traditional medicines has increased in various parts of world. Punicalagin is chemically named as 2, 3-(S)-hexahydroxydiphenoyl-4, 6-(S,S)-gallagyl-D-glucose and belongs to a category of hydrolysable tannin. In this research, the main aim is to formulate the vesicular formulation of Punicalagin which was extracted, isolated and purified from peels of Punica granatum. Thus, to protect its hydrolysis, it is formulated into a nanocarrier system known as niosomes which is based on the preparation of niosomes by using a non-ionic surfactant in varying amounts and keeping the amount of cholesterol constant. The niosomal formulations were evaluated on the basis of evaluation parameters and thus optimized. The best optimized niosome formulation was then formulated as 1% w/w hydrogel and evaluated on the basis of parameters like homogeneity, rheological behaviour of hydrogel, spreadibility and gel strength, consistency, skin retention studies as well as in vitro and ex vivo drug release study. Comparative drug permeation study in vitro, ex vivo and skin retention study of niosomal gel as well as conventional gel concluded that amount of drug permeated and retained in skin from niosomal gel was much more as compared to conventional gel. The analysis of release pattern by niosomal and conventional gel was done by applying kinetic models to them and concluded that both formulations followed zero order kinetics.

Radiation protection against short wavelength radiation have beeen studied by using Barium sulfate-Epoxy mixture. The outcome of this research showed a good new information about the ability of barium sulfate-Epoxy mixture to protect the humans and environment against short wavelength rays. There is an easy procedure, low cost and available materials to construct the shielding instead of that high cost shielding. Increasing barium sulfate ratios in barium-epoxy mixture leads to increased gamma ray attenuation with decreasing gamma photon energy. The results of high attenuation of gamma ray is due to the prevent of the ray to transimitted through the mixture. A new procedure for radiation protection are used in the labs and work places, which were used the radioactive materials. Short wavelength radiation causes hazards on health of humans and environment, the measurement of gamma photons transmission through barium-epoxy mixture are investigated. The count of CPS is done by maestro software after applying the mixture on cement block. There were two decay energys of gamma ray emitting at 59.5 keV and 26.3 keV. The scattering of gamma ray was studied at various angles.

In this works, Human Immunodeficiency Virus (HIV) epidemic model including an eclipse stage of infected cells with latently infected cells was considered. The local and global stability of the system were established using the associated basic reproduction number .Bifurcation analysis was used to establish conditions for the local stability of the endemic equilibrium using the centre manifold theorem. The result shows that the disease free equilibrium is locally and globally asymptotically stable, when the associated disease threshold parameter is less than unity, and the system exhibit backward bifurcation. Numerical Simulations carried out for the analytical result suggest that the attack to the latently infected cells cannot be ignored because some quicker cells from this stage will move with time to productively infected class/cells. Keywords: HIV model; Basic reproduction number; sensitivity analysis; backward bifurcation;

This study presents the impact of board governance mechanism on share repurchase for Malaysian listed companies by using the pooled panel data analysis for a period of six years (2005 to 2010). The result shows that foreign board member, board independent and total remuneration play a significant role in influencing Malaysian companies toward share repurchase.

Trials were carried out using five maize varieties in Ibadan, Oyo state Nigeria in 2010 and 2011 maize cropping seasons. The varieties were planted in a randomized complete block design of three replicates. The objective was to evaluate the relationship existing among various growth and yield components as they contribute to grain yield. The result showed that varieties differed significantly in days to 50% flowering, field weight and number of kernel per cob (P<0.05), leaf area, ear length and 1000 grain weight (P<0.01), plant height and grain yield/ha (P<0.001). ART98-SW5OB and Obatanpa were superior in almost all the agronomic traits evaluated while ART98-SW6 OB was least in plant height and produce flowers earlier than the other varieties. Years, variety and years of evaluation interaction were however not significantly different. Ear length correlated positively and strongly with plant height and number of kernels per cob (P<0.001). Plant height and other agronomical traits were positively associated with grain yield except days to 50% flowering and numbers of kernel per cob. Growth and yield components are related in one way or the other; hence selection for secondary yield traits that correlate positively with primary yield components is fundamental to the overall grain yield development in maize.

ABSTRACT The FT-IR and FT Raman spectra of 3,4-dichlorobenzaldehyde (DCB) and 4-methoxy- 3-methyl benzaldehyde (MMB) molecules have been recorded in the region 4000-400cm-1 and 3500-50cm-1 respectively. Optimized geometrical parameters, harmonic vibrational frequencies and depolarization ratio have been computed by density functional theory (DFT) using B3LYP/6-311+G(d,p) and B3LYP/6-311++G(d,p) method and basis sets. The observed FT-IR and FT-Raman vibrational frequencies are analysed and compared with theoretically predicted vibrational frequencies. The geometries and normal modes of vibration obtained from DFT method are in good agreement with the experimental data. The first-order hyperpolarizability (?0) of the investigated molecule were computed using DFT calculations. The calculated HOMO and LUMO energies shows that charge transfer occur within molecule. Unambiguous vibrational assignments of all the fundamentals was made using the total energy distribution (TED).

Delay is considered as a main problem in civil projects of Iran. Ending the construction of dam in determined time is of high importance in terms of huge capitals invested in dam building projects. The present study has attempted to manage crisis of embankment dams in terms of construction delay reduction. To this end, a questionnaire has been distributed among 50 employers, consultants and contractors of embankment dams’ construction projects. The obtain data has been processed in SPSS software. As the research findings reveals, accelerating the trend of privatizing embankment dams’ construction projects, prioritizing technical and financial capabilities compared to the prices suggested by contractors and supplying required credit to pay lands losses lead to the decrease of construction delay of embankment dams.
