The paper deals with the analysis of RL and RC circuits by using linear ordinary differential equation of first order. Two circuits that consist of a single closed loop containing a resistor(R) and either a capacitor(C) or an inductor(L) connected to a power source ( or voltage source ) in series will be analyzed. Applying Kirchoff laws on ...

Cinnamomumtamala leaf (Bay leaf) is a natural spice usually preferred because of its food flavor and perceived medicinal values. This study investigated the effect of aqueous bay leaf extract (BLE) on hyperlipidermia and gastric ulceration using male Wister strain albino rats. Forty two male rats weighing 150-200g, were fed with high fat diet (HFD) for 10 days. Hyperlipidemia was established. The...

This study investigated the concentration of carbondioxide (CO2) and methane (CH4), temperature and relative humidity on wetlands along Nworie River in Owerri. Data were collected from field survey of six sampling points on the wetlands using handheld AZ 77535 CO2 analyzer and JCB4 gas analyzers. The results showed maximum mean concentration of 703.71 ppm at point A and minimum mean concentration...

Locally brewed sorghum beer is an indigenous alcoholic beverage. It is produced mainly from sorghum grains (sorghum vulgare). The process of brewing involves malting, mashing, souring and fermentation. In this study, bitter leaf (Vernonia amygdalina) extract was used as a means of extending the shelf life of locally brewed sorghum beer which has short shelf life. Chemical and microbial analysis...

Chemistry education is very important for entrepreneurial skills development in students. This paper examines the central role of chemistry education as an instrument for a successful entrepreneurship programme in our institution. The paper discussed the importance of entrepreneurship programmes and chemistry education in Nigeria and suggested that chemistry education should be inculcated into...

Abattoir effluents are known to degrade the quality of receiving water bodies. This study assesses the physiochemical parameters of water side river of which the abattoir is located at Obinze in Owerri west L.G.A, Imo State Nigeria. Water samples were collected from three different points of the water bodies namely the upstream i.e. the point of discharge, middle stream and downstream and...

Every developed economy is built with the technical realization that a sustained availability of quality and affordable electricity in its various forms of generation is fundamental to the provision of jobs, transportation, industrialization, health services, education, housing, clean water, and good sanitation. The insecurity of electric power has become an issue bedeviling sustainable and...
