Interdigitated finger (comb) structures are demonstrated to be effective for exciting electrostatically the resonance of polysilicon microstructures parallel to the plane of the substrate. Linear plates suspended by a folded-cantilever truss and torsional plates suspended by spiral and serpentine springs are fabricated from a 2/~m-thick phosphorus-doped low-pressure chemical-vapordeposited (LPC...

• Value-added products was recycled from antibiotic mycelial dreg (AMD). Antibiotic residue in AMD removed after pyrolysis. N mainly distributed biochar and liquid, while P retained biochar. Low pyrolysis temperature benefits the recycling of P. The disposal by fully conform to related principles. utilization (AMD), which has been identified as a hazardous waste China, are serious concern becau...

abstract efficient use and management of organic matter are important aspects of sustainable agricultural. organic matter is relatively low in majority of soils in iran, and continuous use of n fertilizer would create environmental hazards. therefore, the combined use of n fertilizer and organic wastes is an effective strategy. the purpose of this study was investigating of residual effects of ...

BACKGROUND Fibroblast Growth Factor-23 (FGF23) and cofactor Klotho are key regulators of mineral metabolism in chronic kidney disease (CKD), but little is known about the mechanisms that regulate their production. This study evaluates longitudinal changes of FGF23 and Klotho levels and their regulatory factors in children on chronic peritoneal dialysis (PD). METHODS FGF23, Klotho, 25(OH) vita...

Abnormalities in calcium and phosphorus metabolism are common, and metabolic bone disease develops often in patients with chronic renal failure (CRF). Effective clinical management includes measures to control phosphorus retention and prevent hyperphosphataemia, to maintain serum calcium concentrations within the normal range and to prevent excess parathyroid hormone (PTH) secretion by the judi...

Shifts in manure phosphorus (P) chemical forms and pool sizes induced by water treatment residuals and industrial mineral by-products are largely undefined. We conducted a manure P fractionation study to determine mechanisms of reduction of dissolved reactive phosphorus (DRP) in poultry manure upon mineral by-product additions. The effects of composting on the P immobilization efficacy of the b...
