present study dealt the removal of cr(vi) in a tannery industry wastewater using rice husk silica powder as an adsorbent.the experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different ph against the initial cr(vi) concentration of 292 mg/l. the maximum percentage removal of cr(vi) in the tannery indust...

A volume averaged columnar solidification model, which couples the flow, temperature and solute concentration fields, is applied to simulate experimental continuous casting cases with without vertical electromagnetic stirring (V-EMS). The calculated distribution of magnetic induction intensity final macrosegregation maps are consistent results. Calculation results reveal that V-EMS promotes lon...

Teh ultrasound-assisted magnetic stirrer was used as an effective extraction technique for teh evaluation of total phenolic contents (TPC) and antioxidant potential of ten Pakistani brown rice cultivars. For this purpose, ultrasonic (240W frequency 50/60 Hertz) assisted magnetic stirrer coupled with three solvents methanol, ethanol, and isopropanol in pure and aqueous fractions (80:20) were...

The new Schiff bases are synthesis from various and aldehyde and amine under magnetic stirrer method .The synthesized Schiff base were characterized by spectral techniques (UV-Spectra & IR-Spectra). And the Schiff base are yellow colour solid and having sharp melting point and insoluble in organic solvents.

The introduction of the digestion method (the magnetic stirrer type) resulted directly in the reduction of Trichinella sp. infection among people in Poland. Pork and its products are still the main cause of human trichinellosis in Poland. However, epidemics caused by eating wild boar meat suggested that this way of the transmission of Trichinella sp. larvae to humans might be of considerable im...

A magnetohydrodynamic (MHD) stirrer that exhibits chaotic advection is investigated experimentally and theoretically. The stirrer consists of a circular cavity with an electrode (C) deposited around its periphery. Two additional electrodes (A) and (B) are deposited eccentrically inside the cavity on the bottom. The cavity is positioned in a uniform magnetic field that is parallel to the cylinde...

Cartesian Diver (1) and manometric (2) techniques have frequently been used to measure the respiration rates of nematodes. However, the sensitivity and ease of operation of the polarographic oxygen-sensing equipment currently available offers a technique of great future value to plant nema-tologists. Our recent experience with the YSI Model 53 Biological Oxygen Monitor (Yellow Springs Instrumen...
