Abstract The pyridyl based Schiff base ligands from 2-aminopyridine and benzaldehyde and 2-aminopyridine and 2, 4-dihydroxylbenzaldehyde were synthesized by: 1. For Schiff base from 2-aminopyridine and benzaldehyde; Distillation of Benzaldeyde to ensure maximum purity from possible contaminant like water and ammonia, and refluxed with freshly prepared 2-aminopyridine. The refluxing was done with ethanoic acid catalyst at a time and without catalyst. The process was followed up with Thin Lay...
Smaller structures with sizes ranging from 0.1 to 100 nm are studied in nanotechnology. The pharmaceutical industry is about to undergo a great change as a result of this specialty. It covers various fields such as biophysics, molecular biology, biotechnology, as well as subfields of medicine such as cardiology, ophthalmology, endocrinology, oncology, and immunology. New drug delivery systems are being developed by pharmacies to overcome the shortcomings of conventional methods. This Seminar ...
The global economy has faced an unprecedented threat from the COVID-19 outbreak. The current illness is ravaging Africa at an exponential rate, and all of the continent's nations are experiencing the effects of the epidemic. In this study, we used the COVID-19 outbreak as a case study to examine the prediction of the economic impact of the pandemic in Sub-Saharan Africa (SSA). We adopted several models to work on the dataset to compare which one worked best for all 3 target variables and we d...
Remediation is the process of addressing and resolving problems or issues to make a situation better. In essence, remediation is about taking steps to rectify or improve a situation by addressing its root causes or issues. It's a proactive process that aims to make things right or better than they were before a problem or challenge arose Soil remediation is the process of cleaning, restoring, or improving the quality of soil that has been contaminated or degraded by various pollutants.

Abstract Pension valuation exercises for a defined benefit scheme requires an appraisal of both the schemes assets and its liabilities in different circumstances. The valuations are required to comply with regulatory standards, most notably the minimum funding standard. The objectives of this study are: (i) to compute the estimate of minimum funding standard of pension liability (ii) to establish the actuari...
ABSTRACT An insurance company promises its policyholders to pay out benefits if certain events occur, for example, events such as a car accident and health conditions. When this is happens, the insurance company has a liability to pay the claims by technical provisions or claim reserving. The calculation of claim reserving must be done carefully in such a way that it should not cause loss to the company. Two of the common methods to calculate technical provisions in non-life insurance are the...
ABSTRACT ICT (Information and Communication Technology) has greatly changed contemporary education. The ICT solutions offered enrich learning environments and provide staffs with numerous opportunities. However, even though ICT can enhance education quality, there are many staffs that are unwilling to adjust to the changes brought about by ICT. One of the most crucial inhibitory factors that make staffs reluctant to utilize ICT in education is the lack of their training on ICT. Thus, the purp...
Particulate-filled polymer composites are becoming quite attractive because of their low cost and wide application. Nowadays shells of arthropods and mollusks are widely used as reinforced materials due to their availability and impact mechanical properties. This study focused on theproduction and evaluation of impact strength of snail shell reinforced epoxy composite and as well given concrete information and recommendation on usage with respect to appropriate filler concentration an...
Green leaves and stems have a quite high quantity of water and it’s difficult to obtained an accurate solvent to extract the constituents from the aqueous cells. So the choices of solvent to be used may determine the success of the extraction. In this research work two different solvents were used to extract photochemical parameters in Momordica charantia leaves and stems. The phyto constituents extracted by the solvents from the leaves and stems of M.charantia was compared. In a nutshe...
Problems caused by ambient air pollution on human and the environment can be averted by steadily and strictly monitoring of the concentrations of outdoor pollutants. Human activities have triggered changes in the earths atmosphere. In this research, 7(Seven) selected Eleme communities, 4(four) zones in each community and 28(Twenty eight) sampling points in all locations were assessed for the concentrations of CO, SO2 , NO2 , NO, CO2 , SPM, O2 , noise level and as well Meteorological param...

ABSTRACTAIDS is an acronym for acquired immune deficiency syndrome it cause a destruction of the immune system. It is the most advance stage of HIV viruses (Human Immune deficiency syndrome Virus). This research work is carried out to determine the relationship between male and female HIV patient using data collected from National Tuberclosis and Leprosy training centre Says Zaria. The model arrived in this research. It shows a linear trend model for the male patients Yt=2038 -55.4,364*t show...
Considering a cluster of different hierarchical order with various barrier or cadre levels and steps within levels, there is no availability of a structural framework to help exclusively analyze, formulate, identify, differentiate, and design standardized provisional values to cluster members at various barrier levels and steps within levels. This study designs stepwise analysis, generation, and applications of Kifilideen’s Matrix Structural Framework for an infinite term of increasing...
ABSTRACT: Styrene acrylate resin is a versatile material with a wide range of applications. It is used in a variety of products, including paints, coatings, adhesives, and sealants. The determination of styrene acrylate resin in these products is important for quality control and regulatory compliance. Fourier transform infrared spectroscopy (FTIR) is a powerful technique that can be used to determine the concentration of styrene acrylate resin in a variety of matrices. In this study, a...
ABSTRACT This project is a power bank for laptops, and it is designed to serve as a back up to a laptop whenever there is no power supply and it has a variable knob which controls the output voltage to a desired value. The problem is that we carry different chargers for different gadgets. Though the cost of producing is more costly than the normal chargers we have around but it can serve as a reliable backup considering the problem and solution above a power bank for laptop charger is neede...
