Abstract This study aims to examine the flocculation efficiency of Porphyridium purpureum (i.e. a red marine microalga with high content pigments and fatty acids) grown in seawater medium using polyacrylamide polymers alkaline flocculation. Polymers Flopam™ FO3801 achieved highest over 99% at optimal dose 21 mg per g dry biomass through charge neutralisation bridging mechanism. The addition sod...
PURPOSE The purpose of the present study was to evaluate the flexural strength of the joint between glass-infiltrated alumina frames and the experimental adjusting agent (MA modifier) that contains alumina and magnesia. METHODS A commercially available adjusting agent (Optimizer), a slurry of alumina powder (Alumina modifier), and a bulk specimen (joint-free alumina) were used as controls. Be...
BACKGROUND Patients on continuous ambulatory peritoneal dialysis (CAPD) have increased risk of low-turnover bone disease and relative hypoparathyroidism. Recently, it has been believed that magnesium plays an important role in regulating secretion of parathyroid hormone (PTH). The aim of this study was to evaluate the relationship between serum PTH and serum magnesium as a factor increasing the...
