- Background: Harmful alcohol use is a modifiable risk factor contributing to the increasing burden of non-communicable diseases and deaths and the implementation of policies focused on primary prevention is pivotal to address this challenge. Policies with actions targeting the harmful use of alcohol have been developed in Nigeria. This study is an in-depth analysis of alcohol-related policies in Nigeria and the utilization of WHO Best Buy interventions (BBIs) and multi-sectoral action (MSA) in the formulation of these policies. Methods: A descriptive case study design and the Walt and Gilson framework of policy analysis was utilized for the research. Components of the study included a scoping review consisting of electronic search of Google and three online databases (Google Scholar, Science Direct and PubMed) to identify articles and policy documents with no language and date restrictions. Government institution provided documents which were not online. Thirteen policy documents, reports or articles relevant to the policy formulation process were identified. Other components of the study included interviews with 44 key informants (Bureaucrats and Policy Makers) using a pretested guide. The qualitative data were coded and analyzed using thematic analysis. Results: Findings revealed that policy actions to address harmful alcohol use are proposed in the 2007 Federal Road Safety Act, the Non-communicable Diseases Prevention and Control Policy and the Strategic Plan of Action. Only one of the best buy interventions, (restricted access to alcohol) is proposed in these policies. Multi-sectoral action for the formulation of alcohol-related policy was low and several relevant sectors with critical roles in policy implementation were not involved in the formulation process. Overall, alcohol currently has no holistic, health-sector led policy document to regulate the marketing, promotion of alcohol and accessibility. A major barrier is the low government budgetary allocation to support the process. Conclusions: Nigeria has few alcohol-related policies with weak multi-sectoral action. Funding constraint remains a major threat to the implementation and enforcement of proposed policy actions. 2 results 2

- "Mathematics has diverse applications as decision making tool. This study investigated the use of a proposed pure mathematical formulation (i.e. excluding human factor) for citing appropriately the location of political capital ci of an inhabited designated area. Digitized data of Scale map of Nigeria as a case study was used as input to a FORTRAN 90 programme codes of an equivalent least squares method mathematical formulation. The resulting simultaneous equations involving the political capital city coordinates as unknown variables were solved using Gauss Elimination Algorithm. The political capital city Cartesian coordinate prescribed as (26, 24) in grids unit for the studied case of scale map of Nigeria compared visually satisfactorily with Abuja location on the Map. The Nigeria land area cover was under-estimated by 2.3% referencing 923,768 sq km obtained from Microsoft Encarta Premium (2009). Similarly the Nigeria coastline was estimated. as 25.3% of the country's estimated perimeter (3369 krn). This mathematical tool can be used to cite the centrally located capital city or capital city relocations economically, timely, accurately and reliably. This programme can also be used for citing of capital cities for other countries and center of any irregular shapes on two dimensional plane. " 1 results 1
- "This investigation derived its strong motivation in the adoption of versions of second-order Runge-Kutta methods where there is presently dearth of relevant literature to re-establish .the complicated nature of solution of buffing oscillator dynamics. The choice of second-order Runge-Kutta methods hinged On its simplest algebraic formulation of relevant coefficients based on Taylor series expansion comparing with its higher order counterpart. Validation of FORTRAN-90 codes of algorithms was achieved by phase plots comparison reference to Dowell (1988) as standard. The nature of simulated solutions were visually determined with scatter plot of phase variables obtained from simultaneous implementation of large number of versions of second-order Runge-Kutta methods in conjunction with the corresponding literature results. Validation results are acceptable to within the accuracy limit of Runge-Kutta methods adopted. The scatter plots on phase plane for cases investigated are well structured and bounded (strange) and compare correspondingly well with literature Poincare sections. This investigation re-establishes the complex nature of solution of Duffings oscillator dynamics. Its established procedures provide an alternative Poincare section method and can be utilised for preliminary verification of system dynamics behaviour subject to confirmation by additional dynamics tests.

- "This work investigated the distribution of Von Misses stress in LNG Spherical Carbon Steel Storage tanks. Using the Finite Element Method and equations of elasticity, constant thickness carbon steel spherical storage tanks of 40 in. dia. 70in. dia of 1 in. shell thickness were subjected to different loading conditions from 500 to 4000Psi in incremental of 500 Psi. Spherical triangular elements based on shallow shell formulation were used for the model. The element has five degrees of freedom at each corner node, which are the essential external degrees of freedom without the degree of freedom associated with the in-plane shell rotation. The displacement fields of the element satisfy the exact requirement of rigid body modes of motion. The FORTRAN 90 coding was developed to obtain maximum Von Misses stress distribution with the tank subjected to different internal pressure and wind loadings. The results were then compared with the yield stress of the material of the tank. Von Misses stress is used as yield criteria whether to change tank material or increase the shell material thickness if yield stress is higher than the Von-Misses Stress. Results showed Von Mises stresses for a 40 in dia. Spherical shell with 1 in shell thickness able to withstand internal pressure loading alone up to 3500 Psi after which the shell thickness will no longer be able to withstand the loading. The 70in. dia. Vessel could only withstand internal pressure loading up to 2000 Psi. Validation of Finite Element modeling was done using ASME Section VIII Div 1 standard. Modeled results were observed not to be significantly different from ASME values (P>0.05). External wind effects alone on small dia. vessels was seen to be constant for all sides of the pressure vessel. 1 results 1

- Cough formulations were observed to contain some chemical substances that have been associated with antimicrobial property, namely: menthol, honey, citric acid and volatile oils. A prolonged use of such formulations by patients was therefore considered a health risk on the normal bacterial flora. Nine cough formulations denoted by letter codes along with simple syrup B.P., absolute alcohol and sterile distilled water as controls, were investigated for relative antimicrobial activity on some normal flora bacteria by the agar-cup diffusion method. The respective individual single brands of cough formulation with the exception of one brand exhibited inhibitory activity against 5 - 1 2 bacterial isolates including Escherichia coli, Klebsiella spp, Streptococcus faecalis, Strep. pneumoniae, Strep. viridians, Proteus mirabilis, Staphylococcus aureus and Pseudomonas aeruginosa. Simple Syrup B.P. and sterile distilled water did not exhibit any antibacterial activity while the absolute alcohol exerted activity only on Staph aureus. The antimicrobial activity recorded for the cough formulations could cause a depletion of the normal bacterial flora following a prolonged use of the formulations tested, hence, the attendant health risk of depressed natural immune system of the body, normally associated with such bacteria. pathological status when it presents as a 1 results 1

- Spherical pressure vessels in large sizes are generally supported on legs or columns evenly spaced around the circumference. The legs are attached at or near the equator of the sphere. This research work focussed on flexural-torsional buckling of beam-column supports of field fabricated spherical pressure vessels using finite element analysis. Flexuraltorsional buckling is an important limit state that must be considered in structural steel design and it occurs when a structural member experiences significant out-of-plane bending and twisting. This research has therefore considered the total potential energy equation for the flexural-torsional buckling of a beam-column element. The energy equation was formulated by summing the strain energy and the potential energy of the external loads. The finite element method was applied in conjunction with the energy method to analyze the flexural-torsional buckling of beam-column supports. To apply the finite element method, the displacement functions are assumed to be cubic polynomials, and the shape functions used to derive the element stiffness and element geometric stiffness matrices. The element stiffness and geometric stiffness matrices were assembled to obtain the global stiffness matrices of the structure. The final finite element equation obtained was in the form of an eigenvalue problem. The flexural-torsional buckling loads of the structure were determined by solving for the eigenvalue of the equation. The resulting eigenvalue equation from the finite element analysis was coded using FORTRAN 90 programming language to aid in the analysis process. To validate FORTRAN 90 coding developed for the finite element analysis and the methodology, the results given by the software were compared to existing solutions and showed no significant difference P > 0.05. 1 results 1

- The concept Social cohesion is relative and a somewhat difficult concept to define. Many scholars have offered varying degree of definitions but the main challenge noticed in the definition, is the multiple definitions based on individual scholar’s orientation or ideology .Another problem poised by these definitions of the concept is that of multi-level and multi-dimensional nature. Contemporary scholars of social cohesion have defied a way of treating the concept as a phenomenon with a multi-dimensional feature or as a kind of potentially construct concept structured around many varying indices. Academics and policy makers have unanimously arrived at a consensus that ,"Social Cohesion" as a concept, is enjoying an ever-increasing popularity. Inspite of this perceived ubiquity in many literatures, the concept of social cohesion is still a hugely ill-defined concept that exact meaning varies from one scholar to another. While some scholars or researchers understand the concept as being synonymous to trust, solidarity and peace; many others tend to be of the view that the concept can incorporate such terms as inclusiveness, poverty and social capital. Sociologists however have associated or aligned the concept to ideas that includes social integration and system integration. In furtherance of the search for a clear definition, sociologists have attempted to simplify the challenges embedded in its definition. They highlighted interest in developing a general theory of social cohesion that is confronted with a complex body of work that involves various definitions of social cohesion and engaged specialized literatures on particular dimensions of social cohesion (e.g., membership turnover, organizational commitment, categorical identifications, interpersonal attachments, network structures) and encourage lines of inquiry that is focused on the specific types of groups (e.g., families, schools, military units and sports teams. The apparent theoretical confusion pointed out by other scholar critically is geared towards a critical view of the concept of cohesion which could be viewed as nothing beyond a "quasi-concept" or "concept of convenience" that can be seen to be flexible enough to allow for tweaking, meanderings and also offer rooms for necessities associated with political action in its everyday activities. The goal of the article therefore is to proffer an in-depth analysis of how the concept of social cohesion has been defined and applied in the literature, taking into cognizance the two traditions used in analyzing social cohesion. The first that has its origin in the disciplines of social sciences such as Political Science, Sociology, Social Psychology etc. Coming after social science discipline is the more recent and increasingly significant approaches that were formulated by policy-makers. 1 results 1

- This review focuses on the applications of finite element method (FEM) for heat exchanger analyses. Solutions to convection-dominated heat transfer problems using the Galerkin FEM approximation are always characterised with errors caused by numerical instabilities. Efforts to enhance the stability and exactness of results had led to development of a number of stabilization techniques. Also, there have been algorithms formulated to effectively solve the sparse symmetric and non-symmetric matrix systems resulting from FEM discretised equations of thermal flow problems. The development of stabilization techniques and solvers has made the FEM approach a more formidable computational fluid dynamics (CFD) tool. However, there have been limited uses of finite element CFD codes to heat exchanger applications. 1 results 1
- This study investigated the quality of selected popular poultry feeds available in Nigerian poultry feed market, using growth performance and carcass quality of broiler chickens as indices. Day old broiler chicks were fed with diets obtained from four different commercial feed manufacturers (coded FTE, GFE, PFE and SFE to protect the manufacturers) and control diet (formulated in conformity with recommended nutrient requirements for broiler chickens) over an eight week trial period. There were significant differences (P<0.05) in crude protein, fat and fibre contents of feeds. Crude protein contents of the commercial feeds were found to be below the recommendation level. In some of the feeds the crude fat and fibre contents were higher than the standard levels. The variation in feed quality resulted in reduced feed intake, lower average daily live weight gain, higher feed: gain ratio and lower nutrient retention (protein, fat, fibre) in broilers fed commercial diets when compared with birds on control diet. Live and carcass weight of birds placed on commercial diets FTE, PFE and SFE were significantly lower (P<0.05) than those placed on control diet. Since live and carcass weights of birds are the two major price indices in broiler chicken market, it was therefore concluded that most of the commercial feeds in Nigerian market were substandard. 1 results 1
