HYDRAULIC BEHAVIOR IN THE DOWNFLOW HANGING SPONGE BIOREACTOR Karakteristik Hidraulik pada Bioreactor Downflow Hanging Sponge

Performance efficiency in a Downflow Hanging Sponge (DHS) bioreactor is associated with the amount of time that a wastewater remains in the bioreactor. The bioreactor is considered as a plug flow reactor and its hydraulic residence time (HRT) depends on the void volume of packing material and the flow rate. In this study, hydraulic behavior of DHS bioreactor was investigated by using tracer met...

KOPI Protection instead of Copy Protection

This paper describes how a document can be protected against plagiarism without the need to use heavy copy protection systems, as despite they are hard to break, they make the lives of legitimate users very difficult.

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...

Modification of Itu-r Rain Fade Slope Prediction Model Based on Satellite Data Measured at High Elevation Angle

Rain fade slope is one of fade dynamics behaviour used by system engineers to design fade mitigation techniques (FMT) for space-earth microwave links. Recent measurements found that fade slope prediction model proposed by ITU-R is unable to predict fade slope distribution accurately in tropical regions. Rain fade measurement was conducted in Kuala Lumpur (3.3 N, 101.7 E) where located in heavy ...
