Advances in Sexual Medicine (ASM) , 2017, DOI: 10.4236/asm.2017.72008
Abstract: Background: Some evidence has shown that the prevalence of hypoactive sexual desire and erectile dysfunction (ED) is associated with testosterone levels whilst higher levels of testosterone have been reported to increase the frequency of intercourse. Available evidence points towards an etiologic role for hypogonadism in the causation of diabetes, metabolic syndrome (Mets) and sexual dysfunction (SD) even though the exact pathophysiological linkage is yet to be fully elucidated. This study therefore sought to evaluate the impact of testosterone as well as its bioactive components on both the MetS and SD. Method: Diabetic men engaged in a stable heterosexual relationship for at least 2 years were recruited for this study. Participants were at least 18 years and provided an informed and signed consent to partake in this study. Fasting blood samples were taken from the participants for biochemical and hormonal assay. The participants were then evaluated using the Golombok Rust Inventory of Sexual Satisfaction for males (GRISS-M). Metabolic syndrome was assessed using the NCEP-ATP III, IDF and WHO criteria. All data analyses were performed using the SPSS software, version 11.0 systat, Inc. Germany and GraphPad Prism, version 5.0, San Diego California, USA. Results: The mean total, free and bioavailable testosterone as well as SHBG recorded among the participants was 7.10 ± 1.23 ng/ml, 0.10 ± 0.01 ng/ml, 7.01 ± 1.41 ng/ml and 4.33 ± 1.12 nmol/l respectively. Subjects with the MetS showed significantly lower SHBG levels in comparison with subjects without the MetS. Participants with raised triglyceride levels showed significantly lower levels of total, free and bioavailable testosterone when compared to participant without raised triglycerides. Participants with problems of avoidance and infrequency of sexual activity showed significantly lower levels of total, free and bioavailable testosterone when compared to participants without avoidance or infrequency problems. The +SD/+MetS group recorded the lowest SHBG levels. Conclusion: Testosterone and its bioactive components are associated with male libido as well as the metabolic syndrome. Low levels of free and bioavailable testosterone are true determinants of the MetS in men.
A Comparison of the Statutory Provisions of the United Kingdom (UK) Companies Act 2006 and Ghana’s Companies Act 1963 (Act 179), to the Rule in Foss v Harbottle  [PDF]
Alhassan Salifu Bawah
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, accountably.

Bulletin of the World Health Organization , 2006, DOI: 10.1590/S0042-96862006001200010
Abstract: objective: to determine the demographic and health impact of deploying health service nurses and volunteers to village locations with a view to scaling up results. methods: a four-celled plausibility trial was used for testing the impact of aligning community health services with the traditional social institutions that organize village life. data from the navrongo demographic surveillance system that tracks fertility and mortality events over time were used to estimate impact on fertility and mortality. results: assigning nurses to community locations reduced childhood mortality rates by over half in 3 years and accelerated the time taken for attainment of the child survival millennium development goal (mdg) in the study areas to 8 years. fertility was also reduced by 15%, representing a decline of one birth in the total fertility rate. programme costs added us$ 1.92 per capita to the us$ 6.80 per capita primary health care budget. conclusion: assigning nurses to community locations where they provide basic curative and preventive care substantially reduces childhood mortality and accelerates progress towards attainment of the child survival mdg. approaches using community volunteers, however, have no impact on mortality. the results also demonstrate that increasing access to contraceptive supplies alone fails to address the social costs of fertility regulation. effective deployment of volunteers and community mobilization strategies offsets the social constraints on the adoption of contraception. the research in navrongo thus demonstrates that affordable and sustainable means of combining nurse services with volunteer action can accelerate attainment of both the international conference on population and development agenda and the mdgs.

Advances in Sexual Medicine (ASM) , 2017, DOI: 10.4236/asm.2017.73009
Abstract: Introduction: Alcohol usage has largely been seen as a risk factor for the development of sexual dysfunction as well as erectile dysfunction. Others have reported that prolonged alcohol usage and abuse is compatible with normal sexual function in the absence of endocrinological problems as well as hepatic dysfunction. About seventy five (75) percent of alcoholics have various sexual difficulties with improvements in sexual functions occurring after treatment of alcoholism and psychosexual therapy. It is evident from the various reports over the years that mild and occasional alcohol usage is not as much implicated in the causation of SD and its other forms as heavy, addictive or dependent alcohol usage. Alcohol usage has also long been linked to hypogonadism, testicular atrophy as well as leydig cell toxicity. Alcohol induced hypogonadism has been reported to resolve after withdrawal of alcohol use. Since both diabetes and alcohol usage have been strongly associated with both hypogonadism and sexual dysfunction, it is logical to expect that diabetics who frequently consume alcohol will have a worsened hypogonadal state and sexual function. This research therefore seeks to provide evidence of an association between alcohol consumption in diabetics and a worsened sexual dysfunction in comparison to diabetics who did not consume alcohol. Methods: Type II diabetic patients attending the Diabetic Clinic at the Maamobi General Hospital between the periods of January 2010 and March 2011 were consecutively recruited for this study. Diabetics with other known endocrinological diseases and physical disabilities were excluded from the study. Sexual function was assessed using the GRISS-M. Early morning fasting samples were used in lipid and testosterone profile assays. Results: Study participants who consumed alcohol recorded higher levels of triglycerides and LDL-Cholesterol. They also recorded significantly lower levels of bioavailable testosterone. Furthermore they also recorded higher scores for impotence, premature ejaculation, non-sensuality and infrequency but lower scores for avoidance and were about six times more likely to be infrequent in their sexual activity in comparison with those who did not consume alcohol. Conclusion: Alcohol consumption among diabetic males is associated with hypogonadism and has an impact on several domains of male sexual function. Diabetic males should be advised to avoid alcohol abuse in order to facilitate the management of diabetes associated sexual

Global Health Action , 2010, DOI: 10.3402/gha.v3i0.5517
Abstract: The Millennium Declaration, adopted by the United Nations (UN) in 2000, set a series of Millennium Development Goals (MDGs) as priorities for UN member countries, committing governments to realising eight major MDGs and 18 associated targets by 2015. Progress towards these goals is being assessed by tracking a series of 48 technical indicators that have since been unanimously adopted by experts. This concept paper outlines the role member Health and Demographic Surveillance Systems (HDSSs) of the INDEPTH Network could play in monitoring progress towards achieving the MDGs. The unique qualities of the data generated by HDSSs lie in the fact that they provide an opportunity to measure or evaluate interventions longitudinally, through the long-term follow-up of defined populations.
Application of the Homotopy Perturbation Method to Nonlinear Heat Conduction and Fractional Van der Pol Damped Nonlinear Oscillator  [PDF]
T. A. Nofel
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.56081
Abstract:

In this paper, a powerful analytical method, called He’s homotopy perturbation method is applied to obtaining the approximate periodic solutions for some nonlinear differential equations in mathematical physics via Van der Pol damped non-linear oscillators and heat transfer. Illustrative examples reveal that this method is very effective and convenient for solving nonlinear differential equations. Comparison of the obtained results with those of the exact solution, reveals that homotopy perturbation method leads to accurate solutions.

Exact Solution for Pressure Driven Flow of Two Immiscible Phan-Thien-Tanner Fluids in a Pipe  [PDF]
A. M. Siddiqui, A. Walait, T. Allison, T. Haroon
Open Journal of Fluid Dynamics (OJFD) , 2018, DOI: 10.4236/ojfd.2018.84024
Abstract: This paper provides the exact solutions for the fully developed two layer pressure driven flows of incompressible Phan-Thien-Tanner fluids in a horizontal cylindrical pipe. Exact equations are formulated and solved for important kinematic properties, such as, velocity profiles, normal and shear stresses, total volume fluxes through a circular cross-section and average velocities. Graphical results are provided and discussed for the different flow parameters. A comparison of Upper Convected Maxwell (UCM), Linear Phan-Thien-Tanner (LPTT) and Exponential Phan-Thien-Tanner (EPTT) shows that UCM is a low viscosity fluid as compared to LPTT, and EPTT and LPTT is lighter than EPTT.
Self-Adaptive DE Applied to Controller Design  [PDF]
K. A. Folly, T. Mulumba
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.29007
Abstract:

Adequate damping is necessary to maintain the security and the reliability of power systems. The most-cost effective way to enhance the small-signal of a power system is to use power system controllers known as power system stabilizers (PSSs). In general, the parameters of these controllers are tuned using conventional control techniques such as root locus, phase compensation techniques, etc. However, with these methods, it is difficult to ensure adequate stability of the system over a wide range of operating conditions. Recently, there have been some attempts by researchers to use Evolutionary Algorithms (EAs) such as Genetic Algorithms (GAs), Particle Swarm Optimization, Differential Evolution (DE), etc., to optimally tune the parameters of the PSSs over a wide range of operating conditions. In this paper, a self-adaptive Differential Evolution (DE) is used to design a power system stabilizer for small-signal stability enhancement of a power system. By using self-adaptive DE, the control parameters of DE such as the mutation scale factor F and cross-over rate CR are made adaptive as the population evolves. Simulation results are presented to show the effectiveness of the proposed approach.

Abstract: We have read with great interest the paper which was published in Natural Science, 2014 issue number 6 titled “Estimation of annual effective dose due to ingestion of natural radionuclides in cattle in tin mining area of Jos Plateau, Nigeria” [1]. The paper motivated us to use state-of-the-art computational technique to investigate the risks of the tin mining activity in Jos-Plateau, Nigeria on large mammals (e.g. cattle). The Tier 2 Erica Tool assessment was used to estimate the total dose rate and risk quotients of these reference terrestrial animals. Our investigation revealed that the expected and conservative risk quotients of large mammals due to internal and external exposure to enhanced level of radioactivity are 0.05 and 0.16, respectively. Since the risk quotients are less than unity, this indicates that there is less than 5% probability that the screen dose rate (10 μGyh1) is exceeded. The estimated total dose rate to large mammals is 0.52 μGyh1 which is not statistically significant. A critical analysis of [1] is presented in the introductory part of this paper.
