Abstract—A novel copper(II) complex nanoparticles catalyst was synthesized via precipitation and calcination. The catalyst was applied for the degradation of methylene blue under UV light irradiation. The catalyst was characterized for its physicochemical and structural properties by XRD, SEM, TEM and FT-IR spectroscopic techniques. XRD studies revealed that the particles were monoclinic single phase crystalline structure, the morphology of the nanostructure was confirmed by SEM while the TEM studies revealed that the particles were FCC. FTIR spectra showed the presence of diverse vibrational functional groups. Photolysis of the methylene blue dye indicates no degradation after 1 hour reaction, while the addition of the copper(II) complex nanoparticles catalyst resulted in the decolouration of the dye by ~94%. The efficiency of the catalyst was attributed to the nanoparticle’s morphology.

Abstract—This article introduces a new hybridization between the Kharrat-Toma transform and the homotopy perturbation method for solving a strongly nonlinear oscillator with a cubic and harmonic restoring force equation that arising in the applications of physical sciences. The proposed method is based on applying our new integral transform "Kharrat-Toma Transform" and then using the homotopy perturbation method. The objective of this paper is to illustrate the efficiency of this hybrid method and suggestion modified it. The results showed that the modified method is effectiveness and more accurate.

Abstract—The study investigated the challenges preventing academic planning officers of academic planning unit from effectively using ICT in their offices in Federal University Wukari, Taraba, State, Nigeria. The researchers employed the descriptive survey research design for this investigation. The population of this study consisted of all the academic planning officers in federal university Wukari, Nigeria. The researchers employed Stratified random sampling was employed as sampling technique to select twenty academic planning officers for the study. Questionnaire was used for the study titled ‘Challenges Preventing the Use of Information and Communication Technology in By Academic Planning Officers Questionnaire (CPUICTAPOQ). Responses of participants were based on four-point Likert scale of strongly agree [4], agree [3], disagree [2] and strongly disagree [1]. In order to determine the construct validity, test re-test method was used. For example, using factor analysis, the factor loadings matrix ranged from .632 to .910 in all the items. All research questions were answered using mean. A mean of 1.50 was taken as the bench-mark. That is, a mean of 1.50 and above was considered high and taken as acceptance of constraints in the use of ICT academic planning officers while a mean below 1.50 was considered low and taken as rejection of constraints in the use of ICT academic planning officers. The result collected and analyze revealed inadequate ICT facilities, unstable power supply, unstable internet service, high cost of ICT facilities, poor computer Literacy among academic planning officers, poor implementation of ICT policies in the universities, poor maintenance culture among the academic planning officers, lack of technical support for repairs and maintenance of ICT facilities by universities technians and poor ICT capacity development programme for Academic planning officers are the challenges preventing effective utilization of ICT by academic planning officers in federal university Wukari, Nigeria.
