- " Educators in Nigeria are relentlessly concerned about the need to improve learners’ academic achievement in core subject areas especially in Mathematics, English Language, Science and Social Studies. This is not only because a higher achievement in these core subjects lay foundation for technical skills, social orientation, numerical skills and skills in written and oral communication which are in short supply, but also because higher achievement is particularly valued in a society which sets high premium on academic success as the panacea ' for entrance into more prestigious occupation. This problem may not exist without some causes. This study therefore looked into some factors (school type, gender of the learner, socioeconomic background of a child and school environmental factors) as they affect academic achievement of learners. Survey design was adopted for the study. Proportionate random sampling technique was used to select 17 private and 17 public schools in three Local Government Areas (Obio- Akpor, Port-IIarcourt and Eleme) in Rivers State. In each school selected, 20 students (10 who attended private alongside 10 students who attended public schools) were chosen. In all 34 schools, 680 students (368 males and 312 females) participated in the study. Six valid and reliable instruments developed by the researchers were used to generate information for the study (Integrated Science Achievement Test (ISAT), Social Studies Achievement Test (SSAT), English Language Achievement Test (ELAT), Mathematics Achievement Test (MAT), Students Socio-Economic Background Questionnaire (SSEBQ) and School Environment Assessment Checklist (SEAC). The ISAT, SSAT, ELAT, and MAT were developed to measure student achievement in these subject areas. Their reliability coefficients kuder Richardson (KR20) were 0.81, 0.79, 0.76, and 0.82 for Integrated Science, Social Studies, English Language, and Mathematics respectively. The data was analyzed using descriptive and inferential statistics (frequency, percentages and t-test and ANOVA.) " 1 results 1
- A study was carried out to examine the effects of various antibiotics, salt concentrations and pH on the hatchability of F. gigantica eggs. It was observed that tetracycline concentration of 0.5mg/ml and above inhibited the development and hatching of F. gigantica eggs. Salt concentration of 1% gave low hatchability while 2% concentration and above strictly inhibited the hatching of the eggs. Acidic pH of 3-5 inhibited hatching of F. gigantica eggs while pH of 7-8 promoted hatching of eggs to above 3.4%. The possibility of employing the results of this study to fashion out a control measure against fasciolosis in farm animals is discussed. 1 results 1

- Background: Displaced women are affected by sexual and reproductive health (SRH) challenges, often exacerbated by poor living conditions, limited access to healthcare, and cultural norms. The aim of this study was to explore SRH issues, the effects of displacement into camps on women’s SRH, and challenges with accessing and utilizing SRH services among women in camps for the displaced in Benue State, Nigeria. Methods: A qualitative phenomenological approach was employed to gain an in-depth understanding of the women’s SRH challenges, based on 12 focus group discussions between women of different age groups and eight in-depth interviews. The data were collected using tape recorders and notes. Data analysis followed a thematic approach. Ethical approval and appropriate consent were obtained for the study. Results: The majority of research participants stated that sexually transmitted disease/human immunodeficiency virus was the most serious SRH issue in the camp. Their stay in camp enhanced the women’s vulnerability and exposed them to sex in exchange for basic needs/palliatives, increasing their SRH challenges. Access to and use of SRH services were impacted by their migratory lifestyle, cultural and religious views, lack of SRH knowledge, and other difficulties. Short-term approaches to intervention, health providers’ poor communication, and attitudes were reported to affect SRH service use. Conclusion: There is an urgent need for comprehensive interventions to address SRH challenges among women in displaced settings, including proper coordination of humanitarian services, education on transactional sex, encouragement of men to participate in SRH initiatives, and expansion of access to services, as well as the training and hiring of culturally competent healthcare providers. 1 results 1

- Binary liquid alloys have found wide applications in electronics, communications, automotive and aerospace technologies. The development of new alloys and improvement of existing ones require accurate knowledge of thermodynamic variables of the constituent systems which may not be obtainable experimentally. Hence, there is always the need for theoretical investigation to complement experiment. This study was aimed at theoretical determination of the thermodynamic properties of nine binary liquid alloys. Nine liquid alloys (Al-Zn, Bi-In, Ga-Zn, Ga-Mg, Al-Ga, Sb-Sn, In-Pb, Ga-Tl and Al-Si) with insufficient theoretical investigation were selected for investigation using three different models. Quasi-lattice theory which connects thermodynamic and dynamical properties was employed to determine the concentration concentration fluctuation in the long-wavelength limit [Scc(0)], chemical short range order parameter (α1), free energy of mixing (GM), the concentration dependence of diffusion and viscosity of Al-Zn and Bi-In liquid alloys. Quasi-chemical approximation model for strongly interacting systems was used to investigate ordering and glass formation tendencies in Ga-Zn, Ga-Mg and Al-Ga binary alloys. A statistical thermodynamic theory was used to determine the mixing properties of Sb-Sn, In-Pb, Ga-Tl and Al-Si liquid alloys. The choice of model was influenced by the type of available experimental data. The Scc(0) and α1 showed that a reasonable degree of chemical order existed in Bi-In system, while Al-Zn liquid alloys exhibited a liquid miscibility gap or phase separation at all concentrations. The values of free energy of mixing at the equiatomic composition were -0.4986RT and -0.9344RT for Al-Zn and Bi-In alloys respectively. The free energy of mixing of Ga-Zn, Al-Ga and Ga-Mg alloys are almost symmetrical around the equiatomic composition with Ga-Mg being the most interacting, while Al-Ga is more interacting than Ga-Zn alloy. Apart from Ga-Mg alloys with negative enthalpy of mixing, both the enthalpy of mixing and entropy of mixing of the three Ga-based systems are positive and symmetrical about the equiatomic composition. In the concentration range 0 ≤ cAl ≤ 0.3 and 0.7 ≤ cAl ≤ 1, Al-Ga systems exhibited a glass-forming potential. The free energy of mixing, enthalpy of mixing and entropy of mixing of Sb-Sn and Al-Si liquid alloys exhibited negative deviations from ideality and were symmetric around the equiatomic composition, while In-Pb and Ga-Tl systems exhibited positive deviations with Ga-Tl alloys showing asymmetry behaviour. The compound formation in liquid phase was weaker in Al-Zn than in Bi-In alloys. The Sb-Sn and Al-Si liquid alloys had tendency for heterocoordination, while In-Pb and Ga-Tl exhibited homocoodination. The Ga-Zn and Al-Ga alloys exhibited homocoordination, whereas Ga-Mg alloys had tendency towards heterocoodination. 1 results 1

- COVID-19 emerged in Wuhan, China in December 2019 and within a short period of time it had become a pandemic that will go down in history as a one, perhaps non-intentional, biological warfare against humanity. It not only caused a global health crises but also a crisis in the political, economic, educational, entertainment (including sports, recreation, tourism) and other facets of human endeavours. COVID-19 has challenged the wittiness of biological, basic and applied scientists, educational, communication and other social scientists to bring their expertise on board to curtail its spread. It has also altered day to day national, international governance structures with serious global diplomatic and economic challenges and shrinks the gap between the rich, not so rich and poor nations as it exposes the vulnerabilities of all in response to its threats to lives and livelihoods. Serious efforts are going on to develop pharmaceutical interventions, nevertheless the most cost effective way out is non-pharmaceutical interventions of physical/social distancing, regular washing of hands, use of alcohol based hand sanitizers, consistent and proper use of face masks to halt or limit the spread of the virus. The researchers’ main objective was to unravel the perception, attitude and apathy of residents of Ibadan, Nigeria towards non-pharmaceutical precautionary measures against the spread of COVID-19. MATERIALS AND METHODS This was a qualitative study. It involved residents of Ibadan living around or in contact with the researchers, having been found by the researchers not to be observing non-pharmaceutical precautionary measures against COVID-19. Thematic analysis was done through identification, coding and categorizing patterns or themes in the data collected. RESULTS The study focused on perception, attitude and apathy towards precautionary measures among residents of Ibadan. Thirty people were interviewed, including 8 (26.6%) aged 20-30 years, 10 (30.3%) 31-40, 4(13.3%) 41-50 and 8 (26.7%) aged 51 years above. 19 (63.3%) were Christians while 11 (36.7%) were Muslims. On educational status, 6 (20.0%) had no formal education, 11 (36.7%) had secondary education while 13(43.3) had tertiary education .Most of the respondents, except a few, believed that COVID-19 was not real claiming to have only seen those that had been infected by the virus in the country on different media platforms such as on television and social media platforms. Many of the respondents had a positive attitude while some were indifferent claiming that they could never be infected no matter how they lived their lives. Majority claimed that it was almost impossible to maintain social distance as they had to go out in public cars, visit markets and also visit relatives who would not understand them if they decided to keep social distance. CONCLUSION The study revealed good perception of the disease, poor attitude and apathy towards many aspects of the use of non-pharmaceutical precautionary measures 1 results 1

- Contraceptive use in Nigeria at 15 per cent is low, despite a high human immunodeficiency virus (HIV) prevalence of 3.4 per cent and fertility rate of 5.7 per cent. We assessed the levels of spousal communication on family planning and contraception (FPC) and HIV/acquired immune deficiency syndrome (HIV/AIDS), influence of demographic characteristics on this communication and association between this communication and the respondents’ health behaviours. We used a cross-sectional and nationally representative data on reproductive health and HIV/AIDS-related issues from randomly selected 30,752 men and women of reproductive age. Descriptive statistics, Pearson chi-square (c2 ) and logistic regression were used to analyze the data at 5 per cent significance level. About 61 per cent of the respondents were 25–49 years old and mostly from rural areas (65 per cent). Only 20 per cent of the respondents discussed HIV/AIDS with their spouses within 12 months preceding the survey while 15 per cent discussed FPC. A discussion of both HIV/AIDS and FPC among spouses was reported among 9 per cent compared to 26 per cent who reported discussing either. Respondents aged 35–39 years had higher odds of discussing HIV/AIDS (Odds Ratios [OR] = 7.06:6.16–8.09) than those aged 15–19 years. Urban dwellers also had higher odds (OR = 1.24:1.16–1.31) of HIV/AIDS discussions than rural respondents. Modern contraceptive use was 35 per cent and 23 per cent among respondents who discussed FPC and HIV/AIDS compared to 8 per cent and 9 per cent, respectively, among those who did not. Spousal communication on FP and HIV/AIDS was low and has influenced contraceptive use and HIV positivity in Nigeria. There is a need to encourage spousal discussion on FP and HIV/AIDS, especially among the rural dwellers and the poor and uneducated as a strategy for improving modern contraceptive use. 1 results 1

- Developing countries face enormous social, political and economic problems in addition to being consumer economies that rely almost absolutely on importation. The knowledge production enterprise (in general) and the library and information science (LIS) profession (in particular) suffer due to inadequate media to communicate scholarly works in Nigeria. This paper identifies short lifespan, irregular issues of locally produced journals, and inability to sustain subscription to foreign ones as major shortcomings of LIS journal marketing in Nigeria. It posits that journal sustainability is mainly based on the returns made from journal marketing and distribution. However, the ability of institutions to subscribe to reputable journals is dependent on how well funded they are and every academic relies on the meager monthly allowance s/he earns which is hardly enough to personally subscribe to one good local journal. Moreover, the content and physical qualities of the journals also affect the extent of their marketing and distribution. The cumulative effect of these limitations is the pauperization of the knowledge industry through the unavailability of quality media for communicating research results and limited exposure to foreign research findings. The paper suggests, among other things, that Nigerian Library Association (NLA) and other stakeholders in the librarianship profession should create a regulatory body that would be responsible for setting standards, vetting the quality of, and endorsing journals produced, marketed and distributed in Nigeria 1 results 1

- Distance Learning programmes would simply become impossible tasks without information and communication technologies (ICTs) as well as internet based instructional strategies. These programmes are characterized by learner- centredness, life-long learning, independent learning and recognition of prior learning. Although, the University of Ibadan Distance Learning Centre (UIDLC) is well known for the use of ICTs, more advanced technologies are not prevalent feature of the programmes. This study therefore assessed the level of utilisation of ICTs and internet facilities in the University of Ibadan Distance Learning programmes with respect to their availability and adequacy. The Input- Process- Output evaluation model was employed to guide the study. A sample of 200 participants, selected through multistage sampling procedure was involved in the study. Three research questions guided the study. One validated instrument was used to collect data and its reliability index was 0.86. Data was analyzed using frequency counts and percentages. In terms of availability, usability and adequacy of Information and Communication Technologies: Radio programme service 147(73.5%); Overhead projector 105(52.5%); Video tapes 147(73.5%); Audio tapes 119(59.5%);Computers 145(72.5%); Internet facilities 175(87.5%) and Electronic board 118(59%) were available and in use in the programme, while Interactive television programme service 13(6.5%); Fibre optics 59(29.5%) and Electricity supply were in short supply in the programme. The distance learning institution (UIDLC) is striving to make use of ICTs and Internet facilities on its programmes. However, impact of ICTs goes wider than just the structure and presentation of courses, it must also aim at improving teaching-learning resources, staff capacity development, learner support services, and increase the number of courses available to prospective candidates in order to position distance education in Nigeria for global competitiveness. 1 results 1

- E-commerce has a major impact in the agricultural sector. The way people go about purchasing agricultural products and the way the farmers sell them are important. Sometimes, buyers have to travel far distances to get agricultural products and getting the right quality is not guaranteed. Various market prices cannot be compared because buyers do not have all the time and resources to visit every agricultural farm. Hence, the need for an offline accessible means of trading electronically which would help farmers and other buyers, make their appropriate business transactions online. This study is concerned with the application of Unstructured Supplementary Services Data Application (USSD) and Short Messaging Service to connect farmers to an e-commerce platform. Entity relationship model use case diagram and Unified Modeling Language class diagram were used in the system design. The farmer accesses the offline service via a USSD short code (offline module) and they can then manage their crop inventory and other basic details. Their crop inventory is then synced to the online e-commerce platform for buyers to compare prices, view crop availability and order crops. The farmer can either accept or reject to do business with a buyer via SMS and the buyer will be notified in the All Orders section of the platform. The system helps to connect farmers that do not have smartphones and Internet access to an online marketplace thereby increasing their access to market. 1 results 1
