Phosphates Denmark

The annual impact of shifting all the pig herd in Denmark to a phytase supplemented diet instead of MCP supplemented would be a reduction in greenhouse gases by 27 kT CO2 equivalent, reduction in acidification by 450 T SO2 equivalent, reduction in nutrient enrichment by 1200 T phosphate equivalent, and avoiding mining of 20 kT phosphate bearing rock. 

Concentration and MWD of F-PHEA After Absorption. F-PHEA was determined in perfusate samples by quantitative GPC relative to a freshly prepared F-PHEA standard run on the same day. Either a mixed-bed column (12 x 300 mm Sephacryl S-200 Sephadex G-25 SF 3 1, Pharmacia LKB) or a Separon HEMA-Bio 40 column (8 x 250 mm 10 pm particle size, Tessek A/S, Aarhus, Denmark) was used with a 20 pL injection volume. A mobile phase of pH 7.4 phosphate buffered saline (0.05 M phosphate, 0.15 M NaCl) was supplied (Model LC-7A Bio Liquid Chromatograph, Shimadzu Corporation, Kyoto, Japan) at 0.5 or 1 mL/min. Fluorescent detection was employed (Model RF-535 Fluorescence HPLC Monitor,...

To illustrate the investigation of past human activity, three examples are provided below the discovery of a major Iron Age town in Sweden using phosphate analysis, the investigation of activities inside an Aztec temple discovered in the center of modem Mexico City, and the experimental study of elemental and organic chemistry of an earthen living floor in an experimental Iron Age house in modem Denmark. 

AN-a(s) has been reported to be responsible for the fatal intoxications of ducks and swine (Cook et al., 1989). AN-a(s) was also implicated in the deaths of nine dogs at Richmond Lake, SD, USA in 1985 (Mahmood et al., 1988). One of the first reports of this toxin outside North America was when it was identified in the stomach contents of poisoned birds from a lake in Denmark (Henriksen et al., 1997 Onodera et al., 1997). There have been other suspected occurrences of AN-a(s), including in Brazil (Molica et al., 2005), based on observed anticholinesterase activity but the lack of a commercially available standard and the toxin s labihty render absolute confirmation difficult. AN-a(s) readily loses the methyl phosphate moiety on storage to produce a nontoxic product. 

A Hg/Pt UME can be formed by applying -1.1V vs. Hg/Hg2S04 (Radiometer, Copenhagen, Denmark)) at a Pt UME and contacting it with the mercury (Bethlehem Instr., Hellertown, PA) of an HDME (Metrohm Instr., Herisau, Switzerland) or a Hg pool in phosphate buffer... 

The coenzyme of carboxylase (thiamine pyrophosphate) was shown to be the active form of vitamin B, a method for its estimation was developed, its enzymatic synthesis in animal tissues was demonstrated. Perhaps the most important part of Ochoa s work at Oxford was the discovery of the coupling of phosphorylation with oxidation of pyruvic acid in brain. Here he demonstrated the obligatory relationship between these two processes, a contribution which came almost at the same time as the observations of Herman Kalckar in Denmark and Vladimir A. Belitzer in the Soviet Union. Ochoa was the first to show the formation of three phosphate bonds for each oxygen atom used in the process.
