DISPERSION OF CONTAMINANTS IN GROUNDWATER WITH CHEMICAL REACTION

A mathematical model presented in this paper describes the dispersion and concentration ofcontaminants (fine and coarse) in porous medium with the effect of chemical reaction. Solutetransport in porous media is discussed by means of advection-dispersion equation. The effectof particle mass parameter and reaction rate parameter on the dispersion coefficient and meanconcentration of a chemical so...

Coffee Berry Borer Resistance in Coffee Genotypes

The aim of this study was to evaluate the coffee germplasm of the Paraná Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of less damaged genotypes in the field were evaluated under controlled condition with obligated and free choice experiments established in a randomized complete design with three re...

Determination Of Coffee Content In Coffee Mixtures

The Malaysian Food Regulations 1985 [1] states that coffee mixtures must contain not less than 50 percent coffee. Caffeine content of a coffee mixture is usually used to indicate its coffee level. In this study, coffee content of coffee mixtures was determined based on caffeine concentrations using High Performance Liquid Chromatography (HPLC). Caffeine recoveries from spiked standard coffee mi...
