The sudden Covid-19 pandemic outbreak has forced many universities and students globally to switch from conventional face-to-face learning to remote learning due to government mandates on self-isolation and social distancing to curb the spread of the pandemic. It is extremely necessary to explore the students’ perception on the use of this online Learning that will address university educational needs and policy making. This study aims to explore the perception of the students on how technology enhanced learning adopted by the SBS during the C19 has impact on their academic life, learning productivity that can help the management in policy and decision making. This qualitative study used an interview (semi-structured) to answer the interview questions in relation to the research questions. 15 Postgraduate students of Salford Business School were successfully interviewed and their responses were analyzed using thematic analysis. The study has discovered internet connectivity, distraction and low participation of students in class as difficulties experienced by students in online learning. Students felt depressed and mentally stressed due to the online workload, fear of failure, lack of interaction (socially and academically). Extra learning strategies and alternative internet infrastructure were found to have been used by students to deal with challenges posed by online learning. Results also showed how lack of concentration and distraction have contributed to the reason why students interact less in online learning. The interviewees emphasized on the importance of students-to-students’ and tutors-to-students’ interaction in online learning.

The Internet of Things is an evolving technology for physical objects. Privacy concerns any individual’s right of control. On the other hand, security refers to the way personal data from somebody is safeguarded. Despite the importance of security and privacy management in the IoTs, there are still rising issues confronting the IoTs thus the need to device stronger techniques in addressing these issues. The aim of this paper is to review the security and privacy threats in the IoTs and the prevention techniques. The objectives is to compare the reviewed techniques and recommend a more viable techniques for managing privacy and security in the IoTs. SLR methodology is used to review the techniques based on their ideas, merits, demerits and prospect. Intelligence gathering techniques opined that intelligence should be adopted by companies to boost their security domestically but however there was difficulties in gathering information for big data using the existing mining algorithm. Social-media techniques is capable of using user’s twitters account profile to protect user’s data but it was only limited to information gathering. Soft-biometric techniques is a strong techniques for measuring objects performance and authentication but the error rate of the techniques is high. BITAG Guideline’s security and privacy techniques employed high level policies/guidelines in checkmating security and privacy issues but however detailed list of the guidelines are not specified and threats are left untouched. The authors thus recommended that fuzzy-based security and privacy techniques and new hybrid algorithm techniques should be hybridized for a viable security and privacy in the IoTs.

A Tropical Black Clay (TBC), obtained by method of disturbed sampling, at a depth of between 0.5m to 1.5m, at Gwako village, Abuja, Nigeria, was treated with up to 10% each of Calcium Carbide Residue (CCR) and Coconut Shell Ash (CSA), at 2% variations. Effect of the additives was investigated with respect to compaction characteristics (Maximum Dry Density-MDD and Optimum Moisture Content-OMC) and Unconfined Compressive Strength (UCS). Results of index properties of the soil indicated that it classified under CH and A-7-5, according to Unified Soil Classification System (USCS) and American Association for Highway and Transportation Officials (AASHTO) respectively. There was a general decrease in MDD of the treated soil with increase in dosage of the additives, while the OMC increased with increase in dosage of the additives. Unconfined Compressive Strength (UCS) of the treated soil showed general increase with both increase in dosage of the additives and curing period. It was therefore, concluded that although, 1700 kN/m2 UCS was not achieved within the composition considered, CCR and CSA indicated positive potentials for treatment of tropical black clays.

In this study we optimized the performance of micro horizontal axis wind turbine (HAWT) blade using computational fluid dynamics on the basis of Blade element momentum theory (BEM). A micro horizontal axis wind turbine (HAWT) blade of 1.0m long was design using aerodynamics design parameters such as chord length, lift force, drag force, tip speed ratio, solidity, coefficient of performance, angle of attack, wind relative angle, Reynolds number, efficiency, axial and induction factor were all calculated. The 2D preprocessor Gambit interface was used to generate optimized mesh and boundary conditions for an efficient extraction of kinetic energy of the wind by the optimized blade. The meshed was exported to fluent were it was processed and analyzed based on the boundary conditions as identify on Gambit interface. The simulated blade was design based on average wind speed of 5.3mls measured at 10m height above the ground, which is found to be suitable for some locations in North East, North Central and North West. The results showed that the maximum extractable power was 125.44watts at a relative wind speed (velocity) of 5.3m/s with a Reynolds number of 3.0 at an optimal lift to drag ratio. It’s was also recorded that the increased in wind speed also increase the measured extractable power. The design blade satisfied Newton’s third law and Bernoulli’s effect at an efficiency of 32.1%. Which has the ability to extract and generate energy from the wind; it is a clean source energy that is freely available throughout year with almost zero emission of greenhouse gases and without seasonal variation. The use of this source of energy will reduce frequent blackout and dependence on importation of fossil fuel which is a huge burden to Nigeria economic.

Chemical Engineering Department Federal University of Technology, Minna, Niger State, P. M. B. 65, Nigeria.
Phosphogypsum (PG), the by-product of phosphoric acid industry, comprises of calcium sulfate dihydrate, and other contaminants which restricts the industrial use of phosphogypsum in cement industry as a set retarder. Remedial thermal treatment of phosphogypsum as a set retarder for Portland cement production is investigated in this research work. The SEM-EDS analysis of the raw phosphogypsum sample showed the presence of agglomerates in needle, rhombic and hexagonal shape. The treated PG samples fill and intertwine with each other to form a more compact structure. The XRD pattern of the treated phosphogypsum shows new silica and alumina rich products such as amorphous calcium silicate hydrates (C-S-H) and calcium aluminate hydrates (C-A-H), including crystalline phases of phosphogypsum dihydrate crystals. The sulphite content of the heated phosphogypsum was 43.64%, which translates to a purity of 93.83 %. The phosphorous content reduced appreciably from 1.05 mg/L to 0.38 mg/L and also the fluoride content reduced from 2.22 mg/L to 1.25 mg/L respectively for the raw and treated PG as shown in table 3.2. The compressive strength of the Portland cement produced was also observed to be higher in the treated condition than the untreated condition, due to the removal of the binding obstruction admixtures by thermal treatment of the PG. The heat of hydration value of 294 kJ/kg obtained is in accordance with ASTM C-150 (2015) and meets the requirement for ordinary Portland cement. In conclusion, the laboratory tests performed in this study indicated that phosphogypsum could serve as a replacement of natural gypsum as a set retarder because thermal treatment of phosphogypsum significantly removed the impurities present successfully.

This study assessed the socio-economic implications of inadequate power supply from the national grid in national development especially in the area of industrialization, sampling was done in the form of questioner in some selected areas in all the Local Government Areas (LGA) of the Anambra state of Nigeria. The study adopted the survey and experimental research design methods in all the selected Towns, at the same time, a descriptive statistic was majorly employed for their analysis. The analysis-result showed that there is significant dissatisfaction about quantity of (POWER SUPPY) electricity supplied to consumers in various residencia areas as well as the industrial areas and even at that, the electricity Distribution Company of Nigeria will come up with estimated bill for each house to pay Power Bills even when there wasn’t Power Supply. The implication is that most industries here left the national grid in search of alternative sources of Power Supply to power their industries and this resulted to high cost of production and the national purchasing power had to surfer it in return. Based on the major findings made, the study therefore recommended that (i) Government should as mater of facts, diversify the source of fuel for Electricity (Power) Generating Stations as this will make an easily accessible and available. (ii) Electricity consumers should show patriotism through prompt payment/settlement of electricity bills for continuity, effective and adequate supply in response from the distribution companies. (iii) Government should provide each residential house with Prepaid Meter.

A logic for the analysis of authentication protocols was first proposed by Burrows, Abadi, and Needham (BAN). BAN logic is one of the formal protocol verification techniques that help us to prove whether a cryptographic protocol works correctly. It is a logic of belief, with special constructs for expressing some of the central concepts used in authentication. The logic has revealed many subtIeties and errors in published protocols that are hitherto considered secure. We considered a three-factor mutual authentication protocol based on multi-server environments who’s underlyi ng security is build on cryptography. We analyze the protocol’s security using informal security analysis, the BAN logic.

Azomethine linkage of Schiff base plays an important role in medical field with so many pharmacological activities such as antimicrobial, antiviral, antitubercular and anticancer activity. Schiff base derived from P-nitroaniline and Benzophenone was synthesized using Cu(ll) and Fe(ll) Complexes. Characterization using Infrared Spectral analysis was recorded using FTIR spectrophotometer model CARY 630 within the range of 4000-650.00cm-1. The IR spectra of the Schiff base showed a band around 1628cm-1 which shifted in both spectral of the Cu(ll) and Fe (ll) complexes to 1626cm-1 and 1599cm-1 respectively. Analysis of the Schiff base and its metal complexes were carried out, the result reveal the presence of C=N (azomethine) of Schiff base vibration. Melting point and decomposition temperatures were recorded using an electro thermal melting point apparatus model Mettler Toledo MP50 and the solubility of each ligand using different solvents were measured. the result of the antibacterial activity shows that at varying concentrations, synthesized metal complexes (Cu(II) and Fe(II) complexes) have anti-bacterial activity on some gram positive and gram negative bacterial (i.e. Escherichia coli and staphylococcus aureus) while the ligand do not have anti-bacterial activity. The Research further recommend study to be done on anti-inflammatory activity, anti-cancer activity, anti-tubercular activity and other characterization technique for Benzophenone and p-nitroaniline Schiff base and its complexes.
