Human African trypanosomiasis, which is commonly known as sleeping sickness, is a parasitic vector borne disease. The parasites involved are protozoans belonging to the genus Trypanosoma. To assess the acute toxicity and in vitro antitrypanosomal activity of tacazzea apiculata methanol root extract. Five hundred gram (500g) of the stored sample (roots) of T. apiculata was weigh on a weighing balance and the sample was transferred into a conical flask and macerated in 500ml of 95% methanol. Th...
Aluminum-doped zinc selenide thin films were prepared using the chemical bath deposition technique. The films were characterized to obtain the optical properties, structural properties, and surface morphology using the Cary 300 UV/Visible Spectrophotometer- at normal incidence of light in the wavelength range of 200nm-800nm, the Rigaku miniflex 630 diffractometer, and the JOEL-JSM 7600F machine respectively. The deposited thin films have high absorbance in the UV region with low absorba...
The theory of forecasting exchange rate has been in existence for many centuries where different models yield different forecasting results either in the sample or out of sample (Onasanya & Adeniji, 2013). A country's exchange rate is one of the most closely monitored indicators, as fluctuations in exchange rates can have far reaching economic consequences (Ribeiro, 2016). The recent financial turmoil all over the world demonstrates the urgency of perfect information of the exchange rates (Sh...
Abstract The theory of forecasting exchange rate has been in existence for many centuries where different models yield different forecasting results either in the sample or out of sample (Onasanya & Adeniji, 2013).

ABSTRACT This study investigated the nutritional composition of cooked and raw samples of Cowpea (Vignaunguiculata) and Mung bean (Vignaradiata), two vital legumes in human diets. Proximate analysis, mineral content and vitamin B2 (Riboflavin) compositions were evaluated using standard methods. Results showed significant differences in moisture, ash, crude protein, crude fiber, crude lipid and carbohydrates contents between cowpea and mung bean. Cooked cowpea had higher crude protein (11.25 ...
ABSTRACT The aim of the study is conduct proximate and phytochemical screening of three different varieties of rice bran (Jamila, Gouria 1 and Faro 63 best on the experiment on the rice bran samples of phytochemical screening alkaloid steorids, saponins, flavonoid are found to be present in all the samples while tannis were absent in Gouria 1. Proximate analysis shows significant difference between the three samples. Literature review reveals the importance of the bioactive components in the ...
ABSTRACT The aim of this study was to analyze and determined the microbiological and physiochemical parameters of effluent water samples obtained from different points of collection at point R in Sokoto abattoir, Nigeria and its impact on the microbial population of the receiving soil and river were studied. A total of four samples were analyzed for total heterotrophic bacterial count, fungal count, and coliform count. The media used were nutrient agar, Sabroud’s dextrose agar, eosin methyl...
The global expenditure on diabetes related health care is an estimated USD760 billion a year. Diabetes is one of the leading causes of death in the world and about six deaths per minute are attributable to diabetes complications. In 2019 approximately 1.5 million deaths occur from diabetes annually, As of 2019, an estimated 463 million people had diabetes worldwide accounting for 8.8% of the adult population, diabetes is the 7th leading cause of death globally. Diabetes is a chronic metabolic...
In this work, we briefly present fuzzy operations and related properties. As a precursor for studying fuzzy semigroup, we examine critically the fundamental concept of semigroups.. Finally, we describe some results of fuzzy semigroup with respect to fuzzy operations and α-cut of fuzzy set
Abstract This study is a critical review of theoreticalissues that underline the linear mixed effects (LME) and nonlinear mixed effects (NLME) models. These two areas are revisited under maximum likelihood and restricted maximumlikelihood estimation frameworks. We also review methods of estimating parameters in both linear and nonlinear mixed effects models. In the case of LME, we consider different ways of developing the likelihood estimators, key among these methods are the “pseudo-data�...
This project discusses the influence of genomic structure on phenotypic expression in plants and animals, emphasizing intraspecific variations arising from diverse genomic structures. It highlights historical misinterpretations of structural rearrangements and advocates for comprehensive whole chromosome comparisons. The project focuses on using the SyRI tool to validate findings from whole-genome analysis of sugar beet and sea beet genomes, revealing insights into the role of the Rz2 locus i...
ABSTRACT In our rapidly advancing world, the integration of automation has become pivotal for modern living particularly in car parking management. Hence, this research project is focused on design and construction of RFID-based Car Parking System while utilizing Arduino technology. Defering from manual check-ins, this system employs RFID technology to seamlessly detect and manage vehicles, reducing congestion and enhancing the overall parking experience. The project's standout features incl...
Dyes are used in various industries such as pharmaceutical, cosmetic, paper, leather, food stuff, plastics, and textile etc. The effluents are discharged into the environment by either water or land. The discharge of these effluents into the receiving environments results in hazardous health problems as most of these dyes have carcinogenic effects on the living organisms. Congo red was removed on montmorillonite-silica nanocomposite from solution by adsorption process. The percentage yield wa...

ABSTRACT Overtime, manual approach of managing house allocation is being employed which has resulted in a lot of problems in Abdu Gusau Polytechnic Talata Mafara zamfara State. These problems to mention few are, allocation of already allocated apartment due to lack of proper record, difficulty in calculating the general statistics, poor data security and integrity among others. These aforementioned problems are talked with this new system by providing accuracy in general statistics, proper ke...
