The cypermethrin (synthetic pyrethroids) has shows strong piscicidal activity in freshwater teleost fish Colisa fasciatus for all the exposure periods (24h or 96h) in time as well as dose dependent manner. The LC values decreases from 0.009 (24h) to 0.006 (96h) in winter season (water temp. 16°C) and 0.06 (24h) to 50 0.02 (96h) in summer season (water temp. 28°C). Sub-lethal doses (40 and 60% o...

We develop a dynamic equilibrium model of labor demand with adverse selection. Firms learn the quality of newly hired workers after a period of employment. Adverse selection makes it costly to hire new workers and to release productive workers. As a result, firms hoard labor and under-react to labor demand shocks. The adverse selection problem also creates a market for temporary workers. In equ...

Statement of problem Information on the mechanical properties materials used for manufacturing computer-engineered complete dentures is scarce. Purpose The purpose this in vitro study was to evaluate 3 prepolymerized polymethyl methacrylate (PMMA) resins fabrication computer-aided design and (CAD-CAM) milled (CDs), as well 2 denture base polymers conventionally fabricated CDs. Material methods ...

Acid rain still poses a global problem today, exerting many adverse effects on man, animal, and materials. As its research question, the present study tries to find out whether or not acid rains exist in Akure, Nigeria. For so doing, it determines physico-chemical properties of rain water samples, namely pH, temp, Electrical Conductivity (EC), TDS, acidity, SO4-, NO2-, Cl-, and Free CO2. Accord...
