The study examined the asymmetric relationship between exchange rate volatility and macroeconomic performance in Nigeria covering the period between 1986Q1 and 2019Q4. The Non-linear Generalised Autoregressive Distributive Conditional Heteroscedasticity (GARCH) model was employed. The study was motivated as a result of periodic increase in exchange …
The composition of natural gas varies depending on the field, formation, or reservoir from which it is produced. Since the composition of natural gas is never constant, there are standard test methods that can be used to determine the composition of natural gas and thus prepare it for use. The impurities contained in the gas are led to the formation…
Grain legumes are important sources of protein for nutritional and techno-functional applications. Their protein content is 18-50% protein on dry matter basis. Most of the protein is of the storage type, of which 70% are globulins. The globulin proteins are mainly legumins and vicilins, which are also known as 7S and 11S globulins, respectively. Sev…
Pigeon pea is generally used as a dhal i.e., in split form therefore, it is important to check its splitting i.e., hulling efficiency and maximum dhal recovery. Pre-treatments are commonly given for loosening and removing of the seed coat with retaining its edible portion. Enzymes viz. xylanase, pectinase and cellulose were applied to evaluate the d…
Maize is part of the essential food security crops for which yields need to tremendously increase to support future population growth expectations with their accompanying food and feed demand. However, current yield increases trends are sub-optimal due to an array of biotic and abiotic factors that will be compounded by future negative climate scena…
Diabetes mellitus is one of the most common medical disorders often associated with neurological complications. Peripheral neuropathy is the most common neurological complication from diabetes with a prevalence of 10-26% of newly diagnosed adult diabetics. Diabetic neuropathy is a heterogeneous group of conditions that present with sensory and/or mo…
Sarcopenia has been defined as the loss of skeletal muscle mass and strength that occurs with advancing age and has also been related to many metabolic diseases. In late stages, sarcopenia precedes cachexia, defined as a multifactorial syndrome characterized by an ongoing skeletal muscle wasting, with or without loss of fat mass, associated with poo…
The auxeticity of elastic materials is described and explained by the use of the linear and nonlinear models of elastic deformations for a wide range of strain values up to moderate levels. This chapter consists of three parts - general information on auxetic materials, description of auxetics by the model of the linear theory of elasticity, descrip…
Nutritional profile of pulses has significant importance in human diet with respect to protein and mineral quality and bioavailability. Protein energy malnutrition is widespread throughout the world especially among the developing countries. Pulses being rich in macronutrients such as protein from 20 to 26% and low in calories are most suitable for …
This chapter is aimed at demonstrating how the second vertical derivative method is been applied to gravity data for subsurface delineation. Satellite gravity data of some part of Northern Nigeria that lie between latitude 11°-13°E and longitude 8°-14°N obtained from Bureau Gravimetrique International (BGI) were used for demonstration. The Bougu…
