Long-Run Effects of Exchange Rate Policy on Economic: A Case of Nigeria

Very few erudite scholars of economists realised with conviction the intensely unusual, unstable, complicated, unreliable, temporary shock of exchange rate fluctuation in the economy. This study investigates the long run effects of exchange rate fluctuation on economic growth with particular emphasis on Nigeria between 1970-2012.The study identify the gap between recent economy theory and current economic reality in Nigeria using the Ordinary Least Square (OLS) regression techniques to draw out inferences on the exchange rate dynamics and growth. The Overall, finding, reported that real output is negatively influenced by exchange rate, gross capital formation and positively influenced by broad money supply and fiscal balances, suggesting that fiscal discipline exists but currency depreciation persist. In all, appropriate policy towards boosting the national output require stabilization of currency as well as encouraging investment.

Impact of Microwave Irradiation Energy Levels on Molecular Rotation, Structural, Physicochemical, Proximate and Functional Properties of Potato (Ipomoea batatas) Starch

Starch isolated from potato was subjected to microwave treatment at different energy levels (200 - 800 W) to modify the functional, structural and physicochemical properties, as well as induce molecular rotation of the hydroxyl group on the starch polysaccharide. Proximate analyses revealed that moisture content reduced, while ash, protein, fat and fibre increased after modification. Fourier-transform infrared spectroscopy spectra indicated a strong shift in absorption band of OH from 3441 to 3454 cm-1. Optical light microscopy revealed that starch granules were oval and spherical in shape with hyla on some of the granules. Least gelation concentration reduced following microwave treatment. Compared with the native starch, the pasting parameters of the microwave treated starches decreased, with the exception of set­back viscosity for starch modified at 800 W. Onset temperature (TO), peak temperature (TP) and conclusion temperature (TC) of gelatinization increased in microwave treated starches compared with native potato starch. Also, gelatinization enthalpy increased from 8.21 J/g in native starch to 15.39, 16.36, 17.76 and 38.06 J/g in microwave treated starches at 200, 400, 600, and 800 W, respectively. It was concluded that the energy of microwave irradiation can induce and accelerate molecular rotation of the hydroxyl group on the starch polysaccharide

(R1523) Abundant Natural Resources, Ethnic Diversity and Inclusive Growth in Sub-Saharan Africa: A Mathematical Approach

The sub-Saharan African region is blessed with abundant natural resources and diverse ethnic groups, yet the region is dominated by the largest number of poor people worldwide due to inequitable distribution of national income. Existing statistics forecast decay in the quality of lives over the years compared to the continent of Asia that shares similar history with the region. In this paper, a-five dimensional first-order nonlinear ordinary differential equations was formulated to give insight into various factors that shaped dynamics of inclusive growth in sub-Saharan Africa. The validity test was performed based on ample mathematical theorems and the model was found to be valid. The model was then studied qualitatively and quantitatively via stability theory of nonlinear differential equations which depended on the policy success ratio and classical fourth-order Runge-Kutta scheme implemented in maple respectively. The results from the analysis showed that inclusive growth from abundant natural resources and ethnic diversity in sub-Saharan Africa was a function of policy reform whereby an increase in both equitable distribution of national income and accessibility of common man to the goods and services provided by the state to narrow inequality gap was accompanied with a low level of nepotism

Fluid Dynamic Characterization of a Laboratory Scale Rocked Bag Bioreactor

Single-use technology is being widely adopted for the manufacture of biotherapeutics and cell therapy products. Rocked single-use bioreactors in particular have been commonly used, however, the hydrodynamics have rarely been characterized and are poorly understood. In this work, phase-resolved Particle Image Velocimetry and high frequency visual fluid tracking were used to investigate the flow pattern and velocity characteristics for the first time. The studies were performed on an optically accessible mimic of a Sartorius 2L CultiBag at different conditions. Wave formation was observed and higher rocking speeds caused the fluid to move proportionately out of phase with respect to the platform. Dimensional comparisons of fluid velocities with conventional bioreactors suggest that similar fluid dynamics characteristics can be achieved between rocked and stirred configurations. These results provide a first insight into the fluid dynamics of a novel bioreactor type at relevant process conditions supporting the generation of scale translation laws

Effects of artemether on the plasma and urine concentrations of some electrolytes in rats

This study was carried out to determine the changes in the urine levels of sodium (Na+), potassium (K+), and calcium (Ca 2+) of rats during a week of intramuscular administration of artemether (12.5 to 50.0 mg/kg/day), another one week thereafter and their concentrations in the plasma at the end of the study. At 12.5 and 25.0 mg/kg of artemether, urine Na+ concentration was significantly increased throughout the study (p< 0.05), except on Day 7 (at 12.5 mg/kg) and Day 11 (at 25.0 mg/kg), when it was not significantly different from the control. At 12.5 mg/kg of the drug, urine K+ concentration was significantly increased throughout the study (p< 0.05). Artemether caused no significant changes in urine Ca 2+ concentration in the control rats as well as those that received 12.5 and 25.0 mg/kg of artemether. Progressive and significant reductions in the urine concentrations of all the electrolytes at 50.0 mg/kg of artemether were observed. Their concentrations in the plasma were also significantly reduced at this dose of the drug. A dose-dependent degeneration of the renal tissue of all the experimental rats was also observed. We concluded that high doses of artemether caused progressive degeneration of the renal tissue of rats, inability of the damaged kidneys to concentrate urine, which manifested as excessive water loss and electrolyte depletion

Effects of artemether on biochemical markers of liver function in Plasmodium berghei-infected and non-infected rats

This study aimed at determining changes in plasma activities of some enzymes and concentrations of plasma organic constituents which are often used in the assessment of liver functions in uninfected rats (UNR) and Plasmodium berghei infected rats (INR), following a week of intramuscular administration of artemether (12.5 to 50.0 mg/kg/day). The observed changes were related to the effects of artemether on the liver of the rats. At all the doses tested, the plasma concentrations of total and conjugated bilirubin increased significantly in both INR and UNR. A significant decrease in the plasma concentrations of glucose was also observed in UNR. The levels of cholesterol were significantly higher in INR than UNR. Plasma glutamate oxaloacetate transaminase (GOT) activity was significantly increased in both categories of rats, but more significantly in INR. The activity of plasma glutamate pyruvate transaminase (GPT) increased significantly at 12.5 and 25.0 mg/kg only in UNR, while a significant increase was observed at 50.0 mg/kg in the INR. Photomicrograph of the liver revealed progressive tissue damage which was more pronounced in INR than UNR. We concluded that high doses of artemether are toxic to the liver of both infected and uninfected rats

Changes in some biochemical parameters of kidney functions of Plasmodium berghei infected rats administered with some doses of artemether

This study aimed at determining changes in urine concentrations of sodium (Na+) and potassium (K+) of Plasmodium berghei infected rats during a week of intramuscular administration of artemether (12.5 to 50.0 mg/kg/day) and one week thereafter. Their concentrations and that of creatinine and urea in the plasma were also determined at the end of the study. The observed changes were related to the effects of artemether on the kidneys of the rats. The urine levels of the two electrolytes decreased significantly during treatment (P< 0.05). One week post-treatment with 12.5 mg/kg of artemether, the urine concentrations of the electrolytes increased to values that were not significantly different from that of day 0. At 25 and 50 mg/kg, their urine concentrations still remained significantly lower than day 0 values (P< 0.05). Plasma concentrations of the electrolytes one week post-treatment increased, but they were only significant at 25 mg/kg for K+. A significant increase in the plasma level of creatinine was observed at all the doses of the drug at one week post-treatment. A dose-dependent degeneration of the renal tissue of all the experimental rats was also observed. We concluded that high doses of artemether caused progressive degeneration of the renal tissue of P. berghei infected rats

Central obesity as a precursor to the metabolic syndrome in the AusDiab study and Mauritius

Evidence from epidemiologic studies that central obesity precedes future metabolic change and does not occur concurrently with the appearance of the blood pressure, glucose, and lipid abnormalities that characterize the metabolic syndrome (MetS) has been lacking. Longitudinal surveys were conducted in Mauritius in 1987, 1992, and 1998, and in Australia in 2000 and 2005 (AusDiab). This analysis included men and women (aged 25 years) in three cohorts: AusDiab 2000&ndash;2005 (n = 5,039), Mauritius 1987&ndash;1992 (n = 2,849), and Mauritius 1987&ndash;1998 (n = 1,999). MetS components included waist circumference, systolic blood pressure, fasting and 2-h postload plasma glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, and homeostasis model assessment of insulin sensitivity (HOMA-S) (representing insulin sensitivity). Linear regression was used to determine which baseline components predicted deterioration in other MetS components over 5 years in AusDiab and 5 and 11 years in Mauritius, adjusted for age, sex, and ethnic group. Baseline waist circumference predicted deterioration (P &lt; 0.01) in four of the other six MetS variables tested in AusDiab, five of six in Mauritius 1987&ndash;1992, and four of six in Mauritius 1987&ndash;1998. In contrast, an increase in waist circumference between baseline and follow-up was only predicted by insulin sensitivity (HOMA-S) at baseline, and only in one of the three cohorts. These results suggest that central obesity plays a central role in the development of the MetS and appears to precede the appearance of the other MetS components.<br /
