PURPOSE We analyzed differences in urinary stone composition according to body mass index (BMI). MATERIALS AND METHODS Between January 2007 and December 2010, 505 ureteral or renal stones were collected from 505 patients who underwent surgical intervention. Data on patient age, gender, BMI, urinary pH, and stone composition were collected. RESULTS The patients' mean age was 49.2 years (rang...

Crystallization of struvite (MgNH4PO4·6H2O, MAPH) for both N and P recovery from municipal wastewater is an attractive alternative. The low magnesium concentration in calls low-cost sources. In the present work, precipitation supersaturated solutions was investigated. were prepared by addition either slurry Mg(OH)2 (brucite) obtained hydrothermal treatment oxide (MgO) or using aqueous solution ...

Production of struvite (MgNH4PO4·6H2O) from waste streams is increasingly implemented to recover phosphorus (P), which listed as a critical raw material in the European Union (EU). To facilitate EU-wide trade P-containing secondary materials such struvite, EU issued revised fertilizer regulation 2019. A comprehensive overview supply and its quality presently missing. This study aimed: i) determ...

The release of phosphorus (P) and zinc (Zn) from swine manure compost and from soils applied with swine manure compost can be accelerated by colloidal particles. This study investigated the concentrations and chemical species of P and Zn in water-dispersible colloids (WDCs) collected from swine manure compost by using X-ray absorption fine structure (XAFS) spectroscopy. A filtration and ultrace...

Struvite is regarded as a promising phosphorus (P) fertilizer compared to commercial pristine mineral fertilizers. The aim of this study was determine the effect Phosgreen fertilizer, with struvite its source, on chlorophyll, potassium (K), and calcium (Ca) contents in lettuce grown peat superphosphate. carried out pot experiment different doses P fertilization. presents chlorophyll a, b, total...

Improved crop quality and quantity is the main target of soil fertilization in conventional agriculture. However, organic agriculture, adding nutrients to threshold replenishment lost through every crop. Mineral fertilizers provide essential macro microelements plants for their active growth development. Unfortunately, these kinds easily run off from plant vicinity because frequent watering rai...

In contrast to the previous refinement from photographic data [Ferrari et al. (1955 ▶). Gazz. Chim. Ital.84, 169-174], the present redetermination of the title compound, caesium hexa-aqua-magnesium arsenate(V), revealed the Cs atom to be on Wyckoff position 4d instead of Wyckoff position 4b of space group F3m. The structure can be derived from the halite structure. The centres of the complex [M...
