A new manure treatment technology developed as an alternative to anaerobic lagoons on swine (Sus scrofa domesticus) farms includes solid-liquid separation and subsequent recovery of soluble P as calcium phosphate from the wastewater. The objective was to determine the agronomic effectiveness of this calcium phosphate material. A greenhouse study was conducted with annual ryegrass (Lolium multif...

Newly laid eggs of many insect species store maternal ecdysteroids as physiologically inactive phosphoric esters. In the silkworm Bombyx mori, we previously reported the presence of a specific enzyme, called ecdysteroid-phosphate phosphatase (EPPase), which catalyzes the dephosphorylation of ecdysteroid-phosphates to increase the amount of free ecdysteroids during early embryonic development. I...

A recently suggested mechanism for the stress memory of various metal phosphates is investigated experimentally. Based on first-principles simulations [N. J. Mosey et al., Science 307, 1612 (2005)], it had been argued that atoms with flexible coordination, such as zinc or heavy-metal cations, act as network-forming agents, undergoing irreversible pressure-induced changes in bonding that lead to...

The aim of the study was to assess the influence of various feed phosphates on the structural and mechanical properties as well as on the chemical composition of femurs in adult pigs (weight approx. 110 kg). Three types of phosphates--monocalcium phosphate (MCP), dicalcium phosphate (n-DCP) and calcium-sodium phosphate (CSP)--were used alternatively in pigs fed with the standard feed mixture. T...

Long-chain polyprenols and polyprenyl-phosphates are ubiquitous and essential components of cellular membranes throughout all domains of life. Polyprenyl-phosphates, which include undecaprenyl-phosphate in bacteria and the dolichyl-phosphates in archaea and eukaryotes, serve as specific membrane-bound carriers in glycan biosynthetic pathways responsible for the production of cellular structures...

Canadian Council of Ministers of the Environment, 2003 luminium (Al; CAS # 7429-90-5; molecular weight 26.98) is a silvery-white, pliable metal usually found in compounds as Al 3+ (WHO 1997). It is the most abundant metal in the earth’s crust, and the third most common element (Sparling and Lowe 1996). Aluminium is very light (density = 2.70 g·cm), capable of being hammered, cast, drawn out, ma...

The Present study was Include some physical and chemical characteristics for east southern AL-Hammar marsh south of Iraq during November 2006 to 2007 .The Samples were collected on monthly two stations, first AL-Nagarah second ALBurgah, change temperature. highest temperature value in august 30mºand 25mº station respectively, wheel lowest February 11mº January 10mº station. salinity Ogest 2 par...

Introduction Malignant hypercalcaemia (pseudohyperparathyroidism) is occasionally associated with primary hepatocellular carcinoma (PHC) or cholangio carcinoma which has not metastasized to bone (Becker, Sternberg and Kalser, 1963; Keller, Goldschneider and Lafferty, 1965; Knill-Jones et al., 1970). Normocalcaemia is restored if the tumour is resected or a liver transplant undertaken (Knill-Jon...
