The world economy is changing at an unprecedented rate. The forces of globalization and Information and Communication Technologies (ICT) progress are changing the way people all over the world living. Some countries, especially in the emerging world such as China, Malaysia, India, and Singapore among others, are using this wave of change to drive rapid growth in their economies. Nigeria yet to struggle to come to terms with these fundamental shifts in the global economic order. And for it (Nigeria) to secure its place in the global economy, it needs at least a decade to balance the growth that lays the foundation of this ongoing prosperity. This balanced growth can only come from one place, thus the knowledge based economy. Hence, to build the Knowledge-Based Economy in Nigeria, the security challenges of the phenomena (Knowledge-Based Economy) need to be identified and its possible solutions. This paper presents some of the security challenges for building Knowledge-Based Economy in Nigeria and their possible remedies. © 2015 SERSC.

Objective: To determine the spatial distribution of soil-transmitted helminthiases (STHs) and level of infection in relation to epidemiological factors, and to determine co-infection with schistosomiasis among school-aged children in Gashaka Local Area, Taraba State, North East, Nigeria. Methods: Both urine and faecal samples were collected from school-aged children from January-June 2014. The samples were processed using standard filtration and formol-ether concentration techniques for urine and stools respectively. Remotely sensed images were processed using earth resource data analysis system 9.1 and ArcGis 9.2 softwares. Results: A point prevalence of 11.0% (119/1 080) was reported out of 1 080 children examined. Hookworm infection had the highest infection (5.4%, 59/1 080) followed by ascariasis (3.8%, 41/1 080) and trichuriasis (1.7%, 19/1 080). The spatial distribution of the individual helminths infection showed hookworm infection to be higher in Mayo-selbe (23.8%, 43/180), Gashaka (21.6%, 39/180) and Serti A (12.7%, 23/180) (χ2 = 52.58, P = 0.000). Ascariasis was higher in Serti A (6.7%, 12/180) and Gashaka (6.1%, 11/180) (χ2 = 54.15, P = 0.000), while trichuriasis was higher in Mayo-Selbe (7.2%, 13/180) (χ2 = 54.15, P = 0.000) than the other localities. Considering the overall STHs, localities such as Gashaka (30.0%, 54/180), Mayo-Selbe (23.8%, 43/180) and Serti A (19.4%, 35/180) were significantly infected than other localities (χ2 = 93.68, P = 0.000). The logistic regression model showed that low altitude (< 716 m) was significantly associated (odds ratio = 2.676, confidence interval = 1.981-3.615; P = 0.000) with STHs. Conclusions: Though hookworm infection remains an important public health problem in the area, its infection levels varied between children's locations. The spatial distribution maps in this study are important and useful for planning, evaluating and implementing adequate control programmes for STHs among school-aged children. © 2015 Asian Pacific Tropical Medicine Press.

Objective: To determine schistosomiasis level and risk factors that exposed school-aged children to infection as well as to model schistosomiasis map in relation to altitude and rainfall in Gashaka Local Government Area, Taraba State, Nigeria. Methods: The study was conducted between January 2014 and June 2014. Urine and faecal samples were collected from 1. 080 school-aged children and processed using the filtration and formol-ether concentration techniques, respectively. Results: Irrespective of the schistosomes species, a point prevalence of 10.18% was reported out of the 1080 children examined. Males were significantly infected than their female counterparts (11.75% vs. 8.43%) (χ2 = 4.86; P = 0.027), as well as children aged 6-10 (11.65%, 72/618) and 11-15 years (10.29%, 35/340) than the other age groups (χ2 = 9.274; P = 0.026). No significant difference was observed in schistosomiasis between children whose parents were educated (11.11%, 57/513) and not educated (9.88%, 53/536) (χ2 = 1.342; P = 0.247) and those whose parents are farmers (9.74%, 53/544) and non-farmers (10.63%, 57/536) (χ2 = 0.787; P = 0.375). Proximity to water bodies (distance < 500 m) (odds ratio = 1.809, confidence interval = 1.057-3.094; P = 0.003 1) and fishing (odds ratio = 2.632, confidence interval = 1.397-4.958; P = 0.003) were the risk factors exposing children to infection. The spatial distribution pattern of schistosomiasis showed that the infection was significantly higher in Serti A (22.2%, 26/180) and Mayo-Selbe (21.1%, 38/180) than the other localities (χ2 = 92.99; P = 0.000). Conclusions: This study reported a moderate level of infection among school-aged children with proximity to water bodies and fishing as the main risk factors. The spatial distribution of schistosomiasis in the area will guide in efficient and effective control programmes at local level. It is recommended that continued efforts be made to scale-up distribution of praziquantel to high risk areas so as to curb the progression of the disease. © 2016 Hainan Medical University.

This study investigated the effects of computer simulation instructional packages on senior secondary school students' achievement and retention in genetic concepts. The study adopted a pretest posttest quasi-experimental design with non-equivalent groups. Four research questions were formulated to guide the study. Four null hypotheses were posed and tested at 0.05 level of significance. The population of the study was all the 8,109 Biology students in Gombe central education zone, Gombe state, Nigeria. The sample of the study constituted 121 students derived from the two purposively selected co-educational Senior Secondary Schools in the study area. Data was collected using Genetic Achievement Test (GAT) and Genetic Retention Test (GRT). Mean and standard deviation were used in answering the research questions while Analysis of covariance was used to test the null hypotheses. The study revealed that interactive computer simulation instructional package has significant effect on improving students' achievement and retention in genetic concepts than computer simulation package without interaction. The result also revealed that gender has no significant effect on students' achievement and retention in genetic concepts when exposed to either of the packages. It was recommended that Biology teachers should adopt the use of interactive computer simulation instructional packages for teaching genetics in senior secondary schools. © Medwell Journals, 2016.

We have studied a modified version of the classical restricted three-body problem (CR3BP) where both primaries are considered as oblate spheroids and are surrounded by a homogeneous circular planar cluster of material points centered at the mass center of the system. In this dynamical model we have examined the effects of oblateness of both primaries up to zonal harmonic J4; together with gravitational potential from the circular cluster of material points on the existence and linear stability of the triangular equilibrium points. It is found that, the triangular points are stable for 0 < μ < μc and unstable for μc ≤ μ 1/2, where μcis the critical mass ratio affected by the oblateness up to J4of the primaries and potential from the circular cluster of material points. The coefficient J4has stabilizing tendency, while J2and the potential from the circular cluster of material points have destabilizing tendency. A practical application of this model could be the study of the motion of a dust particle near oblate bodies surrounded by a circular cluster of material points. © 2013 Springer Science+Business Media Dordrecht.

This paper studies the motion of an infinitesimal mass in the framework of the restricted three-body problem (R3BP) under the assumption that the primaries of the system are radiating-oblate spheroids, enclosed by a circular cluster of material points. It examines the effects of radiation and oblateness up to J4 of the primaries and the potential created by the circular cluster, on the linear stability of the liberation locations of the infinitesimal mass. The liberation points are found to be stable for 0<μ<μc and unstable for μc≤μ≤1/2, where μc is the critical mass value depending on terms which involve parameters that characterize the oblateness, radiation forces and the circular cluster of material points. The oblateness up to J4 of the primaries and the gravitational potential from the circular cluster of material points have stabilizing propensities, while the radiation of the primaries and the oblateness up to J2 of the primaries have destabilizing tendencies. The combined effect of these perturbations on the stability of the triangular liberation points is that, it has stabilizing propensity. © 2014 Springer Science+Business Media Dordrecht.

We have examined the effects of oblateness up to J4 of the less massive primary and gravitational potential from a circum-binary belt on the linear stability of triangular equilibrium points in the circular restricted three-body problem, when the more massive primary emits electromagnetic radiation impinging on the other bodies of the system. Using analytical and numerical methods, we have found the triangular equilibrium points and examined their linear stability. The triangular equilibrium points move towards the line joining the primaries in the presence of any of these perturbations, except in the presence of oblateness up to J4 where the points move away from the line joining the primaries. It is observed that the triangular points are stable for 0<μ<μc and unstable for μc≤μ≤1/2, where μc is the critical mass ratio affected by the oblateness up to J4 of the less massive primary, electromagnetic radiation of the more massive primary and potential from the belt, all of which have destabilizing tendencies, except the coefficient J4 and the potential from the belt. A practical application of this model could be the study of motion of a dust particle near a radiating star and an oblate body surrounded by a belt. © 2014 Indian Academy of Sciences.

In this paper we have considered the restricted three body problem (R3BP) in which the more massive primary is triaxial, the less massive primary and infinitesimal body are oblate spheroids, and are encompassed by a belt of homogenous material points. Analytically and numerically, we have studied the effects of triaxiality of the more massive primary, oblateness of both the less massive primary and infinitesimal body and the gravitational potential generated by the belt on the location of the triangular libration points L4,5 and their linear stability. L4,5 do not form equilateral triangles with the primaries in the presence of all or any of the aforementioned perturbations. Due to triaxiality of the more massive primary and oblateness of the infinitesimal body the triangular libration points are seen to move away from the line linking the primaries, whereas they shift closer to the line owing to the oblateness of the less massive primary and the potential from the belt. The range 0 < μ < μc of stability of the triangular points is reduced in the presence of any of the perturbations, except when considering the potential from the belt the range increases, where μc is the critical mass ratio. The oblateness of a test particle (of infinitesimal mass) shifts the location of its libration positions away from the primaries and reduces its range of stability. © 2015, Indian Academy of Sciences.

We have investigated an improved version of the classic restricted three-body problem where both primaries are considered oblate and are enclosed by a homogeneous circular planar cluster of material points centered at the mass center of the system. In this dynamical model we have examined the effect on the number and on the linear stability of the equilibrium locations of the small particle due to both, the primaries' oblateness and the potential created by the circular cluster. We have drawn the zero-velocity surfaces and we have found that in addition to the usual five Lagrangian equilibrium points of the classic restricted three-body problem, there exist two new collinear points Ln1,Ln2 due to the potential from the circular cluster of material points. Numerical investigations reveal that with the increase in the mass of the circular cluster of material points, Ln2 comes nearer to the more massive primary, while Ln1 moves away from it. Owing to oblateness of the bodies, Ln1 comes nearer to the more massive primary, while Ln2 moves towards the less massive primary. The collinear equilibrium points remain unstable, while the triangular points are stable for 0 < μ < μc and unstable for μc ≤ μ ≤ 1/2, where μc is the critical mass ratio influenced by oblateness of the primaries and the potential from the circular cluster of material points. The oblateness and the circular cluster of material points have destabilizing tendency. © Springer Science+Business Media Dordrecht 2013.

Within the frame work of the circular restricted three-body problem (CR3BP) we have examined the effect of axis-symmetric of the bigger primary, oblateness up to the zonal harmonic J 4 of the smaller primary and gravitational potential from a belt (circular cluster of material points) on the linear stability of the triangular libration points. It is found that the positions of triangular libration points and their linear stability are affected by axis-symmetric of the bigger primary, oblateness up to J 4 of the smaller primary and the potential created by the belt. The axis-symmetric of the bigger primary and the coefficient J 2 of the smaller primary have destabilizing tendency, while the coefficient J 4 of the smaller primary and the potential from the belt have stabilizing tendency. The overall effect of these perturbations has destabilizing tendency. This study can be useful in the investigation of motion of a particle near axis-symmetric-oblate bodies surrounded by a belt. © 2014 Springer Science+Business Media Dordrecht.
