Beijing Law Review (BLR) , 2019, DOI: 10.4236/blr.2019.101009
Abstract: This paper adopts the comparative approach in its bid to compare the exceptions to the rule in Foss v Harbottle1 under the statutory provisions of the UK Companies Act 2006 (CA 2006), and Ghana’s Companies Act 1963 (Act 179). The rationale is to critically examine the differences and commonalities of the Companies Acts of both the UK and Ghana. The article argues that minority shareholders in Ghana are given more protection in terms of the avenues opened to them to bring actions against the company or the controlling majority shareholders as compared to what pertains in the United Kingdom.
Restrictive Foreign Sovereign Immunity in the United Kingdom (UK): A Welcome Development in International Commercial Transactions  [PDF]
Alhassan Salifu Bawah
Beijing Law Review (BLR) , 2019, DOI: 10.4236/blr.2019.101010
Abstract: The doctrine of absolute foreign State immunity to a great degree, appeared to stifle commercial transactions between contracting State parties and the private sector. Statute and earlier case law both attest to the absolute immunity of foreign States from the English courts’ jurisdiction. However, latter dicta of the English courts under the UK State Immunity Act 1978 (SIA 1978), successfully made a distinction between instances where a State’s actions were wholly of governmental character and some actions of the government that appeared commercial in nature, with basically features, similar to normal commercial transactions entered into by private individuals and companies. This paper, after a careful and painstaking overview of recent cases, concludes that the drift towards restrictive foreign State immunity by the English courts with respect to commercial transactions entered into by States, is a healthy development that carries the advantage of creating greater transparency, which in turn gives assurance to private individuals and companies that the State could be held liable for a breach of its commercial contractual obligations. Without this development, governments such as the Chinese government, which is basically operating as a “commercial/business conglomerate”, can argue State immunity in disputes involving commercial transactions entered into between the Chinese government and the private sector. This research, would in no small way, encourage private individuals and companies to enter into commercial transactions with sovereign States without hesitation, safe in the knowledge that the UK courts, are ready and willing to hold contracting State parties in commercial transactions, accountable.

Abstract: Analyses are carried out to assess the impact of nuclear data uncertainties on keff for the European Lead Cooled Training Reactor (ELECTRA) using the Total Monte Carlo method. A large number of Pu-239 random ENDF-formated libraries generated using the TALYS based system were processed into ACE format with NJOY99.336 code and used as input into the Serpent Monte Carlo neutron transport code to obtain distribution in keff. The keff distribution obtained was compared with the latest major nuclear data libraries - JEFF-3.1.2, ENDF/B-VII.1 and JENDL-4.0. A method is proposed for the selection of benchmarks for specific applications using the Total Monte Carlo approach. Finally, an accept/reject criterion was investigated based on chi square values obtained using the Pu-239 Jezebel criticality benchmark. It was observed that nuclear data uncertainties in keff were reduced considerably from 748 to 443 pcm by applying a more rigid acceptance criteria for accepting random files.

Physics , 2013,
Abstract: In this work, we study the uncertainty of nuclear model parameters for neutron induced ^{56}Fe reactions in fast neutron region by using the Total Monte Carlo method. We perform a large number of TALYS runs and compare the calculated results with the experimental data of the cross sections to obtain the uncertainties of the model parameters. Based on the derived uncertainties another 1000 TALYS runs have been performed to create random cross section files. For comparison with the experimental data we calculate a weighted \chi^2 value for each random file as well as the ENDF/B-VII.1, JEFF3.1, JENDL4.0 and CENDL3.1 data libraries. Furthermore, we investigate the optical model parameters correlation obtained by way of this procedure.

Abstract: The aim of the study is to determine the concentrations of trace elements in Ghanaian shea nut and shea butter. As part of the study, measurements of the elemental composition of shea butter and shea nut samples were carried out by Neutron Activation Analysis (NAA) using the Ghana Research Reactor-1 (GHARR-1). Samples collected from local markets in the Northern region of Ghana and the National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 1547 Peach leaves were irradiated at the GHARR-1 facility. Validation of the method was done using NIST SRM Orchard Leaves (1571) under the same experimental conditions. Six trace elements (Na, Mn, Al, Cl, Ca and K) were detected with maximum concentration of Na found to be 15±1 mg/kg in SN5, Mn; 7.4±0.8 mg/kg in SN6, Al; 259±3 mg/kg in SN1, Cl; 666±27 mg/kg in SN1, Ca; 0.21±0.04 wt.% in SN4, K; 2.0±0.04 wt.% in SN1, Ce; 3.2±0.06 mg/kg in SN2, Se; 0.12±0.004 mg/kg in SN4, and Sc; 0.40±0.02 mg/kg in SN2 . The concentrations of the trace elements were within the limit laid down for safe human consumption.
An Evaluation of Cost-Effectiveness of Micro Computerized Documentation System/Integrated Set of Information System (CDS/ISIS) Software of Raw Materials Research and Development Council (RMRDC), Abuja

Information Manager (The) , 2008,
Abstract: The cost implication of the use of the micro Computerized Documentation System/Integrated Set of Information System (CDS/ISIS) application software in the library and its effectiveness in performance operations was evaluated to determine the cost – effectiveness. The study population was made up of all the staff involved in the computerization and cataloguing operations of the library. A questionnaire was used to collect data, while percentage and table were used to present the data. The study revealed that the use of CDS/ISIS is more cost effective at the library of Raw Material Research and Development Council, (RMRDC) Abuja because it is given to non-profit making organizations free of charge by UNESCO. When compared with the manual system, the computerized system costs more but it is more effective. In spite of the effectiveness of Computerized (CDS/ISIS) had great potentials as a library application. It is recommended that computer appreciations be included in the curriculum of library schools. Library staff that are using CDS/ISIS should be sent on training and retraining especially at advanced level on how to effectively use CDS/ISIS which will enable them fully understand how to apply (CDS/ISIS) to the functions and management of libraries and its information source, and to serve their clientele better. Since (CDS/ISIS) is not supplied with support services like training and maintenance of the software, users should form a functional user groups in their respective state. The user groups can provide relevant training on the use of CDS/ISIS.
Transurethral prostatectomy in human immunodeficiency virus-infected patients, morbidity and surgical risks in a developing economy
SU Alhassan, SA Aji
Annals of African Medicine , 2012,
Abstract: Human immunodeficiency virus (HIV) infection is increasing world-wide and highly active antiretroviral treatment (HAAT) is allowing afflicted individuals to live near normal life span and acquire surgical diseases of the aged as in the unaffected population. This pose occupational hazards to operating surgeons especially in tropical Africa where the seroprevalence is so high that seroconversion in the medical staff contaminated with the virus is estimated to be as much as 15 times (per annum) more than what obtains in developed. A 63-year old man was admitted to our Hospital with urethral catheter in situ and having failed medical therapy, he opted for transurethral prostatectomy (TURP) which was done without any post-operative complication. He was known to be afflicted with human immunodeficiency virus and on treatment for 3 years. He also had a large but reducible inguinoscrotal hernia for 4 years attributed to lower urinary tract obstruction. He had a Lichtenstein repair of right inguinoscrotal hernia which was complicated by small hematoma that was evacuated. The risk of transmission and surgical morbidity during transurethral prostatectomy could be minimized by adequate universal precaution, pre-testing of all consented patients and wise selection of patients that would benefit from such surgical therapy.

Abstract: Documentary source was used to provide analysis of the BLS projects submitted to Department of Library and Information Science, university of Maiduguri between 2000 and 2006. It was discovered that there was no single BLS project for the year 2001. A total of 355 BLS projects were submitted for the 6 years. In terms of study area 196 (55.21%) projects were on North Eastern Nigeria. It was discovered that case study covers 176 (49.88%) of the projects. The arrangement of the BLS projects by titles in ranked order showed that “problems, development and prospects in libraries” top the list with 46 (12.96%) scores. Low scores were recorded for projects on Current Awareness Services (CAS), Library cooperation, library standard etc with each having 1 (0.28%) project title.
Effect of maternal age on endometrial morphology among Ghanaian infertile women
A Alhassan, CS Abaidoo
Journal of Medical and Biomedical Sciences , 2012,
Abstract: As more women choose to delay childbearing, increasing numbers of them face age-related fertility problems. Normal endometrial receptivity is essential for the establishment of any pregnancy and its evaluation is thus considered a basic goal in the assessment of female infertility. It is unclear as to whether women who present to infertility clinics at older age have age-related endometrial retar-dation or luteal phase defect. This study was designed to investigate the prevalence of luteal phase defect (LPD) among infertile women and its relationship with age. Mid-luteal endometrial biopsies were taken from eighty (80) infertile women attending fertility clinics of Komfo Anokye Teaching Hospital, Magazine Clinic and the Bomso Specialist Hospital in Kumasi metropolis and ten fertile women as control using dilatation and curettage and then processed for light microscopy. The re-sults show that 65.0% of the biopsies of the infertile women were normal in development hence their infertility could be due to other factors. In 35.0% of the biopsies the endometrial development was out-of-phase and therefore suggestive of a defective luteal phase which may lead to a non-receptive endometrium during the implantation window. There was no significant difference when LPD was analyzed according to age suggesting that ageing has no significant effect on endometri-al retardation from this study.

Humic Substances and Mineral Elements Contents of White Grubs and Waste Deposit
AJ Alhassan, MS Sule
Nigerian Journal of Basic and Applied Sciences , 2011,
Abstract: The humic substances and mineral elements content of white grubs (WG) and waste deposit (WD) were analyzed. WG was found to contain higher amount of fulvic acid (16.05 ± 4.28%) and humic acid (9.50 ± 2.06 %) compared to the respective value of 2.75 ± 0.38% and 4.25 ± 1.05 %. It could be inferred that WG accumulate these humic substances (humic and fulvic acids) from the environmental waste and these probably contribute to medicinal properties of the grubs. The mineral elements Fe, Mn, Na, K, Ca, and Co were significantly (p < 0.05) higher in WG compared to the WD, also indicating possible accumulation by the WG. In general the mineral contents of white grub in terms of relative concentration was found to be in rank of K > Mg > Na > Ca > Mn > Zn > Fe > Cu. These elements were found in appreciable amount to meet nutritional requirements. WG could, therefore, be nutritionally and medically relevant.
