Conventional resources of phosphorous are at high risk of depletion in the near future due to current practices of its exploitation, thus new and improved exploration methodologies need to be developed to ensure phosphorous security. Today, some treatment plants recover phosphorous from municipal wastewater as struvite (MgNH₄PO₄·6H₂O). Magnesium is often added to the wastewater as MgCl₂·6H₂O to...

A successful enhanced biological phosphorus removal (EBPR) was observed in both anaerobic-aerobic sequencing batch reactor (An-Ox SBR) to induce growth of phosphorus accumulating organism (PAO) and anaerobic-anoxic (An-Ax) SBR to induce growth of denitrifying PAO (DPAO). Although the EBPR performance of An-Ox SBR was higher by 11.3% than that of An-Ax SBR, specific phosphorus release rates in t...

OBJECTIVES To determine the effects on urine calcium excretion of immobilization by skin traction in patients with pelvic fracture. METHODS In a prospective study, a consecutive series of patients with pelvic fracture treated by skin traction were enrolled. Serum (calcium, phosphorous, alkaline phosphatase, sodium, potassium, uric acid, BUN, creatinine) and fasting urine calcium, creatinine, ...

The cost of drinking water treatment and the taste and odor problems have increased significantly in the past decade. While nitrogen is a concern, phosphorous (P) is generally considered the most limiting nutrient. The majority of P loading to the lake in this area comes from surface-applied poultry litter. Of the 48,000 kg/ yr of phosphorous entering Lake Eucha, 69% is thought to come from pou...

This work investigates the effects of oxygen and humidity on black phosphorous (BP) arsenic (AsxP1−x ) flakes using Raman spectroscopy in situ electric transport measurements (four-probe resistance thermoelectric power, TEP). The results show that incorporation into lattice BP renders it more stable, with degradation times for BP, As0.2P0.8, As0.4P0.6 being 4, 5, 11 days, respectively. P-P peak...

OBJECTIVE Studies with rats have found that an interaction between fructose and magnesium affects macromineral metabolism; high dietary fructose significantly increased kidney calcification in both male and female rats, particularly when dietary magnesium was low. This study tests the hypothesis that an interaction between dietary fructose and magnesium adversely affects macromineral homeostasi...
