Forecasting Model for the Exchange Rate of Dollar to Naira using SARIMAX Approach

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...

Forecasting Model for USD/NAIRA Exchange Rate

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). 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 exchang...

COMPARATIVE STUDIES ON MINERAL, PROXIMATE AND VITAMIN B2 COMPOSITION OF COWPEA (Vigna Unguiculata) AND MUNG BEAN (Vigna Radiata)

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 ...

MICROBIOLOGICAL AND PHYSIOCHEMICAL ANALYSIS OF EFFLUENT FROM SOKOTO MEAT MARKET ABATTOIR

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...

ASSESSMENT OF DOSE-DEPENDENT EFFECT OF ETHANOLICEXTRACT OF COCOS NUCIFERA HUSK ON ACTIVITIES OFENZYMIC ANTIOXIDANT IN STREPTOZOTOCIN-INDUCED TYPE 2 DIABETES IN FEMALE WISTAR RAT

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...

FUNDAMENTAL CONCEPT OF FUZZY SEMIGROUP.

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

Review of Methods of Estimating Parameters In Nonlinear Mixed-Effects (Nlme) Models

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�...

Assessing the effectiveness of the Synthenic and Rearrangement Identifier (SyRI) tool for finding genomic rearrangements; A case study of comparison between RefBeet (Chr3) and Beta vulgaris s

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...

Design and Construction of a Smart RFID-based Car Parking System

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...

Synthesis of Montmorillonite-silica nanocomposite and optimization of adsorption parameters for Congo red adsorption

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...

Database Management System for Housing (A Case Study of Abdu Gusau Polytechnic Talatamafara)

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...

GC-MS ANALYSIS OF BIOACTIVE COMPOUNDS PRESENT IN METHANOL LEAF EXTRACT OF Xylopia aethiopica Linn

Plants have been utilized for medicinal reasons since the dawn of time. Pharmacologists and organic chemists have synthesized a wide range of intriguing chemical compounds from medicinal plants in recent decades, which have shown to be quite useful in the practice of optometry and medicine. There is now an increase in global demand for the use of herbal medicines due to enhanced laboratory research and the pharmacological characteristics of bioactivities from natural sources and their potenti...

Computational biology in proteomics

The broad application of proteomics in different biological and medical fields, as well as the diffusion of high-throughput platforms, leads to increasing volumes of available proteomics data. Computational proteomics is the data science concerned with the identification and quantification of proteins from numerous data and the biological interpretation of their concentration changes, posttranslational modifications, interactions, and subcellular localizations. Computational proteomics is a h...

The Statistical Analysis on Road Traffic Accidents in Nigeria

ABSTRACT  Biologically, every living thing has a general property. One of these properties is movement. As a result of this movement, some hazard can occur. One of these hazards is accident. Generally, in Nigeria, the major mode of movement is by road. Road accident has become a major threat to lives of citizens of the country especially during the festive period. The increasing magnitude of fatal road traffic accident globally has been attributed to population explosion and increased leve...
