Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104501
Abstract:
Introduction: Skin whitening is the act of brightening the skin complexion by using substances that are applied on the skin or administered into the body by other means. The use of skin whitening agents has its drawback in terms of causing harmful effects such as skin disorders like depigmentation, rashes, pimples, discolorations, kidney damaged, cancers, neurological and psychiatric disorders depending on how the agents for skin whitening are used. Objective: The paper examines the knowledge, attitude and practice of skin whitening by university female students in north eastern Nigeria, where some dark skinned women in particular tend to bleach their skin. Method: A cross sectional descriptive study. Results: The awareness level of the students about skin whitening agents and their harmful effects was found to be high among the students and little below, half of them are already users of such agents mainly for beautification. Few of them think the use of skin whitening agents can be addictive and lead to social stigma but they don’t believe that the use of such agents should be restricted to medical only. Conclusion: Majority of the female students in the Universities in north-eastern Nigeria bleach their skin with dangerous chemical agents meant for other reasons mainly to attract the opposite sex despite having high knowledge of the harmful effects. Government is highly recommended to take the necessary steps to curtail such menace.

M. O. Amodu, M. T. Bolori, A. Kuchichi, Ibrahim Musa Ngoshe, F. L. Bukar
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105827
Abstract:
Introduction: Different forms of cultural practices are being practiced in Nigeria and other parts of the world. Some of such are beneficial while others lead to negative impacts. Female genital mutilation as one type of harmful traditional practices is a form of violence against women. Female Genital Mutilation (FGM), practiced in many parts of the world, also known as female circumcision or female genital cutting (FGC), is the practice in which a female child undergoes a process involving the female external genital organ being removed partially or totally for nonmedical reasons, causing a lot of health and other problems during, shortly after the procedure and later in life. Objective: The objective of the study was to understand knowledge and thoughts of women towards female genital mutilation. Method: A cross sectional descriptive study. Results: Most of the respondents were aware of FGM but not as high as in the southern part of Nigeria. The majority knew the meaning of FGM and thought it as a harmful practice done for various reasons. Conclusion: FGM has negative impacts. It is highly recommended for government to enlighten parents more about menace of FGM through community and school health education.

Journal of Mazandaran University of Medical Sciences , 2006,
Abstract: Background and purpose: Selection of suitable parameters for brain MRA requires accurate measures, because the image quality depends on the location of arteries, veins and also the velocity differences of blood, taking into account the low blood flow in small veins and arteries, use of paramagnetic contrast media is recommended. Hence, in present study, we investigated the imaging optimization of brain vessels using contrast media in 1.5 T field.Materials and Methods: For image optimization blood T1 was estimated after the injection of 0.1mmol/kg of Gd-DTPA and the relative blood signals were measured at T1=300, 600, 900 and 1200ms using TR=20ms and TE=7ms parameters. Ernest angle and relative signal increased as the T1 decreased. MRA was obtained in three groups, each including five volunteer patients using parameters TR=20ms, TE=7ms and flip angle 10, 20 & 30 degrees in two series without and during contrast injection.Signals of carotid, M.C.A and thorcolar herofili and SD in air were measured and it was shown that in 20 degrees flip angle, C/N was maximum.At the last stage, three series of MRA, without, during c.i and 15 minutes after c.i where obtained in 20 volunteer patients using parameters TR=20ms, TE=7ms and flip angle 20 degrees and calculated C/N .Results: After statistical analysis the highest C/N was observed during c.i MRA. Paired t-student test was performed to compare the differences between the C/N ratios. For clinical purposes one vein and two arterles were graded in 5 definite levels.Conclusion: Results indicated an important effect of paramagnetic contrast media on better observing of small arteries and vein. The best quality was taken during c.i, but in some arteries contrast media did not improve the quality of MRA.
Is There Any Difference of Financial Features between Bidder and Target Banks in Nigeria Mergers and Acquisitions?  [PDF]
Bukar Umar Bolori
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104729
Abstract:
The Nigerian Banking sector has suffered problematic times since 1999, when the sector was facing problems of corporate governance as identified by the Central Bank of Nigeria. However, CBN started embarking on a comprehensive reform agenda since that time and many measures have been taken to bring the sector on the right track by imposing an IMF Code of Good Practices on Transparency in Monetary and Financial policies. Mergers and Acquisitions (M & A) is a process “where two or more companies are combined to achieve certain strategic and business objectives”. Therefore, Merger and Acquisition seems as a means of achieving business and strategy objectives. The study examined the differences of financial features among bidder and target banks in the Nigerian commercial banking sector. The findings of paired t-test on financial features among bidder and target banks show that bidders and targets’ mean of each variable and financial features between bidder and target banks for 3 years (2002-2004) average indicates that bidders and targets’ mean of each variable are statistically different at 5%. Similarly, the findings for bidder banks’ performance of 5 years (2000-2004) before and 5 years (2006-2010) after mergers and bidder banks’ performance of 3 years (2002-2004) before and 3 years after mergers (2006-2008) are also statistically different at 5%. The study recommends that managers of large and efficient banks seeking to go for merger and acquisition should halt from targeting small and less efficient banks because it will lead to operational inefficiency.

Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103944
Abstract:
Introduction: Human Behavior is important as one of the determinants of transmission of Human Immunodeficiency Virus (HIV) infection. The risk of getting infected with HIV as well as subsequent developments and reactions after the infection has a direct bearing on human behavior. Positive behavior change of HIV infection prevention is less than the level of awareness and knowledge pertaining the disease among PLWHA. Method: A cross-sectional descriptive study was carried out on PLWHA attending clinic at the University of Maiduguri Teaching Hospital. A structured interviewer administered questionnaire was used to collect data by systematic random sampling technique. The objective of the research was to understand more about the behaviour of PLWHA and make recommendations on how to improve the behavioral change communications among PLWHA to curb the menace of HIV infection. Results: The people living with HIV/AIDs may be knowledgeable and having high awareness on HIV/AIDS but may not necessarily reflect into good behaviors concerning, taking the right steps to prevent menaces of HIV infection. The behavior of PLWHA was found to have gaps that portend danger in regard to making life more miserable to victims and portend more risk of getting others infected. The gaps are mainly related to psychological issues (e.g., lack of enjoyment or with condom use), beliefs, stigma and financial issues. Conclusion: Counselling should be used to inculcate technic, good morals, attitude and practices among PLWHA to prevent them from deliberate or spontaneous attempts to infect others with the virus. Safer and satisfying sex can be promoted through expanding knowledge and awareness about HIV/AIDS and removing stigma among the general populace through community health education as well as through schools’ curricula. Empowerment of the youths in public and private settings discourages exchanging sexual intercourse for financial gains.
Changes in the Institutional Context of the Ombudsman System in the Republic of Hungary in 2012  [PDF]
Máté Szabó
Beijing Law Review (BLR) , 2012, DOI: 10.4236/blr.2012.33015
Abstract: After the landslide electoral victory of the Fidesz-KDNP in 2010, the new Hungarian government with a two-thirds majority in Parliament adopted a new Constitution which significantly modified the previous institutional structure. Written by the former Commissioner for Civil Rights (as the Ombudsman of general competence used to be called) who is now Commissioner for Fundamental Rights, this article describes, analyses and evaluates the changes which terminated the previous Ombudsman system consisting of four Commissioners and established an independent authority to uphold information rights on the one hand, and a unified Ombudsman structure with increased responsibilities and powers on the other hand.

M. Makeswari, T. Santhi
Journal of Water Resource and Protection (JWARP) , 2013, DOI: 10.4236/jwarp.2013.52023
Abstract:

Competitive adsorption of malachite green (MG) in single and binary system on microwave activated epicarp of Ricinus communis (MRC) and microwave assisted zinc chloride activated epicarp of Ricinus communis (ZRC) were analyzed. The preparation of ZRC from Ricinus communis was investigated in this paper. Orthogonal array experimental design method was used to optimize the preparation of ZRC. Optimized parameters were radiation power of 100 W, radiation time of 4 min, concentration of zinc chloride of 30% by volume and impregnation time of 16 h, respectively. The MRC and ZRC were characterized by pHzpc, SEM-EDAX and FTIR analysis. The effect of the presence of one dye solution on the adsorption of the other dye solution was investigated in terms of equilibrium isotherm and adsorption yield. Experimental results indicated that the uptake capacities of one dye were reduced by the presence of the other dye. The adsorption equilibrium data fits the Langmuir model well and follows pseudo second-order kinetics for the bio-sorption process. Among MRC and ZRC, ZRC shows most adsorption ability than MRC in single and binary system.

The Theory of Coherent Synchronized Reactions: Chemical Interference Logics  [PDF]
T. M. Nagiev
Materials Sciences and Applications (MSA) , 2015, DOI: 10.4236/msa.2015.62019
Abstract: Various types of possible interactions between reactions are discussed. Some of them are united by the general idea of chemical reaction interference. The ideas on conjugated reactions are broadened and the determinant formula is deduced; the coherence condition for chemical interference is formulated and associated phase shifts are determined. It is shown how interaction between reactions may be qualitatively and quantitatively assessed and kinetic analysis of complex reactions with under researched mechanisms may be performed with simultaneous consideration of the stationary concentration method. Using particular examples, interference of hydrogen peroxide dissociation and oxidation of substrates is considered. Therefore macrokinetic theory of coherent synchronized reactions is offered.

M. Kathiresan, T. Sornakumar
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2010, DOI: 10.4236/jmmce.2010.91007
Abstract: Aluminum based metal matrix composites (MMCs) offer potential for advanced structural applications when high specific strength and modulus, as well as good elevated temperature resistance, are important. In the present work, aluminum alloy-silicon carbide composites were developed using a new combination of vortex method and pressure die casting technique. Electrical Discharge Machining (EDM) studies were conducted on the aluminum alloy-silicon carbide composite work piece using a copper electrode in an Electrical Discharge Machine. The Material Removal Rate (MRR) and surface roughness of the work piece increases with an increase in the current. The MRR decreases with increase in the percent weight of silicon carbide. The surface finish of the machined work piece improves with percent weight of silicon carbide.
Reverse Monte Carlo Modeling of the Rigidity Percolation Threshold in GexSe1-x Glassy Networks  [PDF]
Moneeb T. M. Shatnawi
New Journal of Glass and Ceramics (NJGC) , 2015, DOI: 10.4236/njgc.2015.53005
Abstract: Based on Maxwell’s constraint counting theory, rigidity percolation in GexSe1-x glasses occurs when the mean coordination number reaches the value of 2.4. This corresponds to Ge0.20Se0.80 glass. At this composition, the number of constraints experienced by an atom equals the number of degrees of freedom in three dimensions. Hence, at this composition, the network changes from a floppy phase to a rigid phase, and rigidity starts to percolate. In this work, we use reverse Monte Carlo (RMC) modeling to model the structure of Ge0.20Se0.80 glass by simulating its experimental total atomic pair distribution function (PDF) obtained via high energy synchrotron radiation. A three-dimensional configuration of 2836 atoms was obtained, from which we extracted the partial atomic pair distribution functions associated with Ge-Ge, Ge-Se and Se-Se real space correlations that are hard to extract experimentally from total scattering methods. Bond angle distributions, coordination numbers, mean coordination numbers and the number of floppy modes were also extracted and discussed. More structural insights about network topology at this composition were illustrated. The results indicate that in Ge0.20Se0.80 glass, Ge atoms break up and cross-link the Se chain structure, and form structural units that are four-fold coordinated (the GeSe4 tetrahedra). These tetrahedra form the basic building block and are connected via shared Se atoms or short Se chains. The extent of the intermediate ranged oscillations in real space (as extracted from the width of the first sharp diffraction peak) was found to be around 19.6 ?. The bonding schemes in this glass are consistent with the so-called “8-N” rule and can be interpreted in terms of a chemically ordered network model.
