    Specific answers are required for purpose of better communication with many researchers, manufacturers, and users of polymer worldwide. This paper posted so many questions about the research activities on bio-based/ renewable thermoset polymers as against petrochemical based thermoset polymers. Quite a few answers were given but the remaining unanswered questions will surely be required in order to better understand the results achieved in this research area

    ICT Use in Preschool Science Education: A Case Study of Some Private Nursery Schools in Ekiti State

    This research reveals ICT uses in Ekiti preschool education and explores this use of ICT for science education. This case study is part of a wider research project concerning the use of Information and Communication Technologies (ICT) for teaching main natural science’s concepts and mathematics in early year’s classroom. The study was conducted during 2013-2014 school year and pupils participated in the study. The integration of ICT into preschool education has become a high priority for everybody involved in the learning process. The Mathematics and Science Achievement Test was given to pupils and semi-structured interviews with young children were conducted in 16 preschool classes in Ekiti state. Pupils in the control group received only the traditional science instruction about natural sciences (solubility, recycling) and mathematical concepts (comparison, classification and general knowledge of numbers). Pupils in the experimental group received only the science instruction with the use of ICT for the same topics. Both the experimental and the control groups consisted of classes from the same participating schools. The incorporation of ICT in early year’s classes in private schools in Ekiti state should be considered as a means of an obligatory modernization of learning and teaching methods.The results of the research showed that teaching and learning through ICT as an innovative teaching method can be successful for understanding the concept of numbers and natural sciences phenomena at preschool level.

    Use of ionic liquids as a means of recovering value from key organic waste streams in Nigeria

    Two novel processes based on ionic liquid methodology, including steps to recover the ionic liquids for reuse and recycle, are developed for the recovery of key value components from food wastes: namely glycosaminoglycans (GAGs) from seafood waste (scallop gut) and chitin-glucan complexes from cider yeast wastes. Both these components are high-added value materials in nutraceuticals and the chitin- glucan complexes are of particular interest because they are recovered from a vegetarian source. GAG recovery from scallop gut involves treatment of the wet waste with the ionic liquid, HBetNTf2, in a low temperature (30oC) process to separate the insoluble GAG mixture from other components of the waste, which are soluble. The important aspects of this process from the point of view of economic viability are: (i) it is a low-temperature process, (ii) the extraction of the unwanted components occurs quickly, (iii) the product GAGs are obtained in good yield, and (iv) all solvents used can be recovered. The recovery of chitin-glucan involves enzymatic pre-treatment of the cider yeast waste to give a digested pellet from which the complex can be recovered by treatment with the IL, BMIMCl. Two low temperature ionic liquid processes (TESA/TESAC and P6,6,6,14 Cl) for re-refining waste lubricant oils to recover base oils, of sufficient quality to be reused in lubricant applications, are also developed. The TESA/TESAC process is based on a reversible reaction from a solvent, TESA, in which the base oil is soluble to an ionic liquid, TESAC in which the base oil is insoluble. The conversion occurs when carbon dioxide is passed through the solvent and reversed by heating above 50oC. In the P6,6,6,14 Cl process the base oils are recovered from a direct solution of the hydrocarbon content of the waste in the ionic liquid. In both processes all solvents used can be recovered for reuse.Open Acces

    Blockchain technology (BT) is becoming increasingly important in international banking. BT is a distributed immutable encrypted digital and tamper proof ledger for recording transactions. BT will revolutionize international banking with effortless funds and wire transfers across borders. A SWOT analysis is performed as an environmental scan to assess strengths, weaknesses, opportunities, and threats for BT in this case study

    The Impact of Blockchain and Algorithm on FinTech

    Get PDF
    The dawn of the 21st century have witnessed the emergence of several technologies targeting the financial sector. The FinTech industry is gradually maturing and covers an array of financial services on the global economy (Laidroo, Koroleva et al. 2021). However, it is needless to state that FinTech is still at its early stage of development. This research explores and highlight the great profitability FinTech has on all asset class and the abundance it gives on the return on investment. FinTech and Blockchain are prevalent topics among technology leaders in finance today. Algorithms govern the peer to peer decentralized network using machine learning techniques. This is owed to the advancement in processor pace and ample data gives room to more financial analysis

    Knowledge, attitudes and practices towards voluntary HIV counselling and testing among adolescents of a senior high school in Nigeria

    Get PDF
    Voluntary counselling and testing (VCT) for HIV is a vital tool in HIV prevention and care, available information indicates low uptake among Nigerian adolescents despite effort at combating the scourge of HIV/AIDS. A cross sectional quantitative descriptive study was conducted to describe the knowledge, understand the attitudes and practices of VCT among adolescents of senior high school in Nigeria with the aim of informing VCT services and policies. A systematic random sampling of 100 adolescents was done and data collected by means of structured self-administered questionnaires. The study revealed inadequate knowledge on VCT among the study participants which is probably responsible for their poor VCT uptake. Free VCT services and availability of VCT services within the school are factors that could motivate VCT uptake among the students. There is need to enhance dissemination of VCT information among youth and create youth-friendly VCT services to increase VCT uptake among adolescentsHealth StudiesM.A. (Public Health
