Thermal Stability, Transparency, and Water Sensitivity Properties of Bleached, Cross-Linked Cassava Starch Film
(Journal of Digital Food, Energy ans Water Systems (JD-FEWS), 0024) J. Y. JIYA; M. ABUBAKAR; I. A. JOSEPH; E. C. EGWIM; K. T. OBANIMOMO
This work investigates a novel study of the effect of bleaching and cross-linking cassava starch film. Native cassava starch was bleached with hydrogen peroxide (H2O2), cross-linking was carried out with oxidized sucrose, while glycerol was added to enhance the plasticity of the film. Operating temperature and time of 90 °C and 10 Minutes, respectively, adding 0.5 ml of glycerol gave the best bleached, cross-linked cassava starch film. UV-visible spectrophotometer analysis revealed that the cassava starch film produced at the above reaction conditions retained 88.2 % of its transparency at 96 hours of water immersion. The water solubility test shows that the film experienced 52.02 % weight loss after 96 hours of immersion in water. The thermo-gravimetric analysis (TGA) shows a significant improvement in the thermal stability with a Temperature peak (Tp) of 420.75 °C, compared to 374.13°C Tp of the control sample (unbleached, uncross-linked) of the cassava starch film.

An Overview of Users Information Seeking Behaviour on Online Resources
(International Journal of Organization of Scientific Research Community of Researcher, 2014-02) Esew, Micheal; Makarfi, Aisha; Goshie, Rhoda Wusa; JImada, Aisha
This paper discuses online information seeking behavior of students for sustainable education among students of higher learning institutions. Online information seeking behavior is a relatively new phenomenon. However, it is the active process of obtaining data from the Web. Libraries and Universities are continuously adapting and seeking effective ways to respond to the fundamental and interconnected missions of research, teaching and community service, and that is why some have embraced the use of the Internet in service delivery. On the other hand, this study is more concerned with maximizing usage of this resource by students in fulfilling their primary aim of research and reaching out to these resources on the Internet using the requisite navigational skills. The paper says the Internet offers widespread access to electronic resources and also has the advantages of interactivity, and information tailoring. It also agrees that access is inequitable and use is hindered by navigational challenges due to numerous factors e.g. disorganization, technical language and lack of permanence. Meager information evaluation skills add to students' vulnerability. The paper highlights some information seeking models to assist students in their search for information on the Internet. Also it highlights the role of the library in the information seeking process of students. The paper concludes that though Information and communication technologies are being put in place for use by students, they must possess the requisite skill to use them appropriately.

(National Association of Library and Information Science Educators (NALISE), 2014-04-21) Abdulkarim, Murjanatu; Ukashatu, Hamza; Goshie, Rhoda Wusa
The paper explained how the traditional or analogue libraries have transformed into a digital library with the advent of information and communication technologies (ICTS). The concept of ICT based on libraries were highlighted as electronic library, virtual library, digital library, community library, library without walls, the library of the future etc, ICT facilities available for the library and information center were also provided such as computers, printers, email, UPS, CDROMs, Scanners, Printers, Satellites, Internet, Intranet, connectivity, V-SAT, online databases, Websites, etc and the advantage of using them were highlighted such as provision of remote access information to users and access to unlimited information from different source. Challenges of ICT in the library were also highlighted such as; lack of adequately trained manpower in the use of IT. The service provided by library and information with ICT was also provided such as remote enquiry services, interactive services, catalog on web, the services of the intermediates or paraprofessional staff may not be undermined, because they are also very important in the modern-day library. They assist the professional staff in the library such as register users online, transform the physical form of catalog into the online public access catalogue (OPAC), answering users queries online, charging and discharging and giving online literacy instructions to users as part of digital reference service. Also, the paper concludes that, intermediary library staff must acquire all the requisite skill through training and retraining for capacity building in the area of ICTs in the library.

(Proceedings of the Annual Conference of the Nigerian Library Association, Niger State Chapter, Federal Polytechnic Bida, 2017) Abduldayan, F.J.; Galadima, J.H.; Jimoh, S.A.
This research is on the use of university’s emailing system in the provision of effective selective dissemination of information in Ibrahim Badamasi Babangida library, Federal University of Technology, Minna. Emailing system is a technology that can be deployed on any mobile technologies especially mobile smart phones, tablets, and other handheld devices. Preliminary investigations revealed uncertainty on the rate of use of mobile technology in providing SDI in the university library neither is there a comprehensive database captured for such purpose. As a result, this research is aimed at studying the level of awareness the provision of SDI has attained in the university, the presence of mobile technology infrastructure put in place, hindrances to provision of this service via mobile technology and necessary steps to curb the stated hindrances and challenges. A survey research design was adopted in the study and the target population were the academic researchers and librarians who were administered questionnaires and interviewed respectively. A total of 755 copies of questionnaire were administered; 389 copies were returned and found usable. The collected data was analyzed and presented using simple percentages and frequency counts whereby the responses were made across different ranks in the academic cadre and two librarians were interviewed. Findings revealed that lack of constant internet data bundle and mobile access to emails hindered effective access to SDI on the part of researchers, while librarians were faced with several delays due to bureaucratic processes for considering submitted reports as well as funding of internal projects and network downtime challenges on the part of library administrators. The study recommended that the school should improve SDI awareness among researchers through HOD’s and Deans of Schools especially during board meetings, and adopting an automated SDI system supported with a clear-cut policy for SDI provision in the university.

(Nigeria Journal of Engineering and Applied Sciences (NJEAS), 2018-02-22) Kolo, D. N.,; Tsado, T. Y.,; Abdullahi, M.,; Yakubu, D.M.,; Aguwa, J. I.
The quest for the provision of adequate housing for all has translated to the increase in activities of Building construction industry in Nigeria. This growth is accompanied however with cases of poor safety performancewhich at times leads to structural failure. This study investigates and analyses safety performance in Nigerian construction industry. Investigatory survey research method (work study) was adopted to appraise the aim and objectives of the study through field and questionnaire approach. Questionnaire survey consisting of a five point Likert scale was conducted to solicit information from the respondents, and a total of 120 questionnaires were issued to construction professionals and workers on the sites visited. 92 questionnaires representing 76.67% response rate were retrieved and analysed using Statistical Package for Social Sciences (SPSS) version 21. Communalities test, Principal Component Analysis along with ANOVA were utilised for data analysis. A total of thirty-two (32) factors influencing safety performance were identified from literature, subsequently principal component analysis was utilised to reduce the list to nine (9) significant principal factors. The top nine principal factors influencing safety performance determined from the research are: Relationship between Supervisors and Employees on site, Geographical Location (Environmental Factors: Natural and Working Environment), Working Procedure, Ear defenders not worn (while working under noisy equipment), Talk by Management on Safety, Tidy Site, Safety Communication, Operatives job experience and Ladders used without being tied secured. These factors were further incorporated into a regression model. The adjusted coefficient of determination of the model was 0.98; this shows that the model has the capability of explaining 98% of variability in the data under consideration. This implies that the model is adequate in evaluating safety performance. It is therefore recommended that key industry professionals and stakeholders should channel available resources to the determined nine (9) principal safety performance factors.

Recommendations included the need for awareness and orientation on what constitutes plagiarism, citation and referencing education.
Towards a Digital Policing in Developing Nations: The Nigerian Context
(International Journal of Innovative Technology and Exploring Engineering (IJITEE), 2019-05) Idris Ismaila; Victor Y. Legbo; Adeyemi R. Ikuesan; Shaka A. Imavah; Abdullahi B. Mohammad; Fatimah J. Abduldayan; Meshach Baba
Technology-assisted living is a growing trend in most developing nations, particularly for young-aged demographic countries, as it presents a platform for personal development and knowledge management. However, this societyscaping trend has also introduced the myriad opportunity for the formation of complex crime, which is often beyond the (immediate) capability of the policing entity in developing nations. To address this lingering and futuristic problem, particularly in Nigeria, this study developed a context-based digital policing framework for the enhancement of the Nigerian Police. This Nigerian-context framework presents the viability and relevance of the digital policing mechanism in addressing challenges ravaging society. Furthermore, it also presents a modality for improving and enhancing the policing apparatus of the Nigerian society, as a model for other developing nations. The knowledge from the Nigerian-context of digital policing has both research and societal implications. In terms of research, it opens the community of security researchers into the contextual characteristics of digital policing as well as the probable research direction required to implement digital policing in developing nations. With respect to society, knowledge provides a substratum for the integration of the community-policing model.
