Formation of bobierrite (magnesium phosphate) crystal aggregates by acinetobacter sp.

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

A study on phosphate uptake by Acinetobacter sp. in presence of arsenate under aerobic condition

Phosphate is the main hindrance for the removal of arsenic from the arsenic contaminated waste water. Therefore, phosphate removal from contaminated water has become imperative for the successful removal of arsenic. In the present study, an attempt was made to remove phosphate from the waste water by Acinetobacter sp. in the presence and absence of arsenate. When phosphate (25 ppm) containing s...

Influence of Magnesium in the Formation of Phosphate Spheres

Magnesium reduces calcium oxalate crystal formation in human whole urine.

1. A low urinary magnesium was induced in normal volunteer subjects by giving cellulose phosphate; magnesium was added in vitro to yield urine samples of normal and high magnesium concentrations. 2. After rapid evaporation of these urine samples at pH 5.3 to standard osmolality the calcium oxalate crystals were measured by microscopy and isotopic methods. 3. There was a clear inverse correlatio...

MODELLING STUDIES OF MAGNESIUM-DEPENDENT PHOSPHATE ESTER PROCESSING ENZYMES by

Chapter 1. Magnesium-dependent phosphate ester processing enzymes frequently employ a carboxylate-bridged dimetallic unit in their active sites. Biomimetic modelling chemistry of these magnesium centers has not been investigated previously. An brief introduction of the enzyme systems is presented, along with the focus of the present work. Chapter 2. Several dimagnesium(II) complexes were synthe...
