Abstract The quality of raw water in Surabaya is decreasing, and conventional treatment units are no longer efficient treating to become drinking water. Microfiltration membranes applied sedimentation can produce better results on limited land that uses a small number chemicals. material will be deposited the membrane’s surface throughout filtration process. deposition these materials cause fou...

In a paleo-parasitological analysis of soil samples obtained from V-shaped pits dating to the ancient Baekje period in Korean history, we discovered Ascaris lumbricoides, Trichuris trichiura, and Clonorchis sinensis eggs. In light of the samples' seriously contaminated state, the V-shaped pits might have served as toilets, cesspits, or dung heaps. For a long period of time, researchers scouring...

The application of process control automation software for the recycle of peroxide bleaching rinse water to fabric scouring on a continuous preparation range is presented. Analytical data taken on wastewater samples document operating conditions of the preparation range and the quality of the recycle water. An economic analysis of the recycle process and the cost of range modifications to insta...

Here we introduce a new, instrument controlled valving scheme for the centrifugal platform which is based upon dissolvable film (DF) technology. Liquid, restrained at any point upon the disc, is prevented from wetting a DF via a trapped gas pocket. From this pocket a pneumatic channel runs to a sealed vent located on the top surface of the disc. Controlled scouring of this seal by a robotic kni...

1,2-Dichloroethane, also called ethylene dichloride, is a volatile, clear, manufactured liquid that is not found naturally in the environment. It has a pleasant smell and a sweet taste and burns with a smoky flame. 1,2-Dichloroethane is readily soluble in water and several organic solvents such as alcohol, chloroform, and ether. 1,2-Dichloroethane is one of the most widely produced chemicals in...

Enteric disorders are common in sheep and have major economic consequences attributable to dags, production losses and mortalities. The purpose of this paper is to provide a review of non-infectious intestinal conditions in sheep with an emphasis on the role of nutrition and the effects of various nutritional factors . The principles of treatment and prevention are discussed, but not reviewed i...
