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.

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.

Isyaka M. Tom, Muhammad M. Ibrahim, Askira M. Umoru, Jidda B. Umar, Musa A. Bukar, Ali B. Haruna, Abdullahi Aliyu
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105528
Abstract:
The major innate barrier to the establishment of infections in internal tissues is the skin, the disruption of which leads to wound formation. Such wounds can be contaminated by bacterial pathogens thereby hampering the healing process and its management becomes resource demanding. Here, we assess the diversity of potential bacterial pathogens in the infection of different types of wounds among hospitalized patients. Three hundred and twenty wound swab samples were collected and processed via microscopy, and cultured on Blood, MacConkey and Chocolate Agar. Isolates were further confirmed using biochemical tests and Kirby Bauer disc diffusion test was used to determine their antimicrobial susceptibility pattern. 87.5% of samples collected yielded bacterial growth comprising of single bacterial isolates (52.17%) and polymicrobial/mixed growth (47.82%). Staphylococcus aureus (32.61%) was the most prevalent bacterial specie identified. Gram-negative bacteria (62.33%) were the most pervasive group, chief among which were E. coli (23.64%) and Pseudomonas aeruginosa (17.13%). Rate of infection was highest among Wound sepsis and Burns wound where Enterobacter spp. and Streptococcus spp. were the most prevalent respectively. Differences in wound type in relation to rate of infection with Gram-negative bacteria was statistically significant (f = 5.9592; df = 29; p-value = 0.001645; p < 0.01; Mean ± SD = 7.633 ± 6.3706). Resistivity profile of isolates has shown that the most significant resistance rate was against Amoxicillin and Ampicillin, among Gram-positive and Gram-negative bacteria identified respectively. This suggests that wounds can be infected by potential bacterial pathogens which can exacerbate the progression of the wound and complicate the healing process.
An Appraisal of Spatial Distribution of Solid Waste Disposal Sites in Kano Metropolis, Nigeria  [PDF]
Ali Ibrahim Naibbi, Umar Musa Umar
Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.511003
Abstract: This paper describes a research project that has been conducted as part of the Kano Municipal waste management strategy. The aim is to quantify and to identify the existing locations of waste disposal sites by mapping their spatial distribution within the metropolitan Kano. QUICKBIRD satellite imageries; locations of existing waste disposal sites collected using Global Positioning System (GPS); and topographical map (1:5000 scale) of Kano metropolis were used to generate data for the study. The data were prepared and analysed using ArcMap 10.2.1 and Erdas Imagine 11 software to produce the spatial distribution maps for solid waste disposal sites within the metropolis. The result shows that out of the 300 existing waste disposal sites assessed, the city has fairly well-distributed waste disposal sites. Conversely, the disposal sites are more clustered in the centre of the metropolis than the outskirts. However, about 80 percent of the sites are either located very close to roads, settlements or water bodies. Also, while about 92 percent of the existing waste disposal locations are open space, only about 7 percent are containers (closed dumping sites). Correspondingly, about 89 percent are authorised dumping sites and only about 11 percent are unauthorised illegal. The study recommends that policymakers should intervene and relocate the existing unauthorized dump sites to more suitable areas.
Anti-plasmodia activity of leaf extracts of Calotropis procera Linn
SY Mudi, A Bukar
Biokemistri , 2011,
Abstract: The leaves of Calotropis procera were air dried, grounded and soaked with ethanol. The extracts obtained (29.79g, CP1) was fractionated sequentially using aqueous methanol with petroleum ether, chloroform and ethyl acetate respectively. The residue of ethanol extract (marc) was extracted with 5M HCl, basified and extracted with chloroform. These were labeled as CP1-01 to CP1-05 for the plant. Each of these fractions was phytochemically screened to detect the class of secondary metabolite present. The fractions obtained from the plant were found to be selectively active against brine shrimp larvae. These fractions were also subjected to antimalaria parasites bioassay. Fractions CP1, CP1-04 and CP1-05 were found to be active against tested organisms, withCP1-04 being the most active. CP1-04 was further subjected to activity guided column chromatography that led to the isolation of two pure compounds CP1-04-1 and CP1-04-61. Compound CP1-04-61 was found to be active against the malaria parasite. This was further purified and subjected to qualitative and quantitative analysis.
Antibacterial and antifungal effect of high pH and paraffin wax application on tomatoes, oranges and peppers
AM Magashi, A Bukar
African Journal of Biotechnology , 2007,
Abstract: The antibacterial and antifungal effects of high pH (9, 10) and paraffin wax were determined. Determination of antibacterial and antifungal activity of the combined treatments was achieved by aerobic mesophilic count of bacteria and fungi on the surface of the tomatoes, peppers and oranges using serial dilution and pour plate techniques and compared prior to and after 4 days of treatment with buffer (pH 9, 10) and wax for 3 min using dipping method. Reduction in bacterial and fungal count indicates antifungal and antibacterial activity. A bacterial count reduction of 84.3 (control), 63.4 (pH 9) and 78.2% (pH 10) and fungal count reduction of 53.6 (control), 43.4 (pH 9) and 73.5 (pH 10) were achieved after 4 days of treatment respectively. The study shows that the control (unwaxed) had similar antibacterial and antifungal effect as waxed fruits at pH 9 and 10, except for pH 10 that had higher reduction of fungal counts than the control, showing prospect of higher activity with wax at higher pH than 10.

Steady Magnetohydrodynamic Equations for Quantum Plasmas  [PDF]
Muhammad Asif, Umar Bashir
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.312233
Abstract: Steady Magnetohydrodynamic (MHD) Equations of force, density and energy for quantum plasmas have been derived. These equations constitute our Steady Magnetohydrodynamic model for quantum plasmas. All the quantum effects are contained in the last term of quantum force equation and in the last three terms of quantum Energy Equation, so-called Bohm potential and may be valuable for the description of quantum phenomena like tunneling.
The Collinear Libration Points in the Elliptic R3BP with a Triaxial Primary and an Oblate Secondary  [PDF]
Jagadish Singh, Aishetu Umar
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.42034
Abstract:

This paper examines the motion of a dust grain around a triaxial primary and an oblate companion orbiting each other in elliptic orbits about their common barycenter in the neighborhood of collinear libration points. The positions and stability of these points are found to be affected by the triaxiality and oblateness of the primaries, and by the semi-major axis and eccentricity of their orbits. The stability behavior of the collinear points however remains unchanged; they are unstable in the Lyapunov sense.
