Objectives : Determination of reaction order (n) and rate constants (k) the CaCO<sub>3</sub> scale formation that was accelerated by HVI (high voltage impulse) induction.Methods inducted to synthetic solution containing 2.5 mM Ca<sup>2+</sup> ion at different temperatures 25, 40, 60℃. The concentration has been monitored as voltages increased from 0 5, 10, 15 kV. Reactio...

The pineapple waste from the industry has contributed to an increase in Malaysia and worldwide every year. A major type of endopeptidase enzymes found is fruit bromelain, stem ananain, comasain. This study aims extract purify protease crown MD2 pineapple. Protease was extracted purified using anion exchange chromatography, gel filtration, desalting before being identified liquid chromatography-...

A quick method of performing the Paul-Bunnell reaction is described which is as sensitive as the orthodox method. When read at two hours the rapid test appears to be definitely more sensitive than the orthodox method. When the rapid method is performed in the later stages of glandular fever a much higher titre is obtained than by the orthodox method. This might prove to be of diagnostic importa...

Abstract Contaminated salted shellfish were a suspected cause of the 2019 hepatitis A outbreak in Korea; however, no virus was detected by detection tests used. In this study, we investigated shortcomings these for identifying to serve as guide improvement tests. Salted washed and desalted before collecting mid‐guts testing. For verification method, first inoculated with norovirus then RT‐qPCR ...

Phosvitin is the most phosphorylated naturally occurring protein and it concentrated in granular fraction of egg yolk. It has interesting antioxidant cation chelating properties that can be used to preserve food cosmetics, but its industrial application limited as separation relies on use organic solvents chromatographic techniques, which are expensive difficult assimilate a continuous procedur...
