Reactive phosphorus undergoes diagenetic transformation once transferred into marine sediments. The degree of regeneration and redistribution of phosphorus depends on early diagenetic and environmental conditions, which may be linked to larger scale phenomena, such as bottom water circulation, water column ventilation, and organic carbon flux. Phosphorus phases of the 50m-sized fraction of deep...

Ecosystem management requires the explicit treatment of interactions between humans and ecosystems. An exploratory model for integrating social and ecological dynamics was introduced to study ecosystem management strategies. This paper focuses on the management of lake eutrophication. The model was developed to include the dynamics of the lake, the behaviour of agents using phosphorus for agric...

Mixed anhydrides of phosphorus sulfonic acids RR'P(O)OSOzR" 1 are of interest in the biological transfer of sulfates'. In the chemical synthesis of oligonucleotides, phosphoric sulfonic anhydrides 1 (R', R = nucleoside) are postulated as important and reactive intermediatesw-s-. Anhydrides 1 were also suggested as intermediates in biooxidation of thiolophosphates'. Structural analogues of anhyd...

Treatment of polluting discharges from abandoned mines is producing large quantities of ochre (mainly iron (III) oxides) for which no major end-use has yet been identified. At the same time, phosphorus pollution is a serious threat to the water environment in industrialised countries, causing eutrophication, algal blooms, fish kills and loss of water resources. Newcastle and Edinburgh Universit...

To increase the phosphorus recycling potential from swine slurry, mineral phosphorus products which could be used as fertilizers should be obtained and new processes need to be investigated. A routine method is needed to better evaluate the dissolved and solid mineral phosphorus in swine slurry. Cold perchloric acid extraction method previously developed for wastewater or sludge analysis was ad...

From the last few years, the inclusion of microbial phytase in poultry diets has increased significantly, mainly in response to heightened concerns over phosphorus pollution of the environment as cheaper means to make phosphorus available to birds from phytate. Phytate is the major form of phosphorus, abundantly found in cereal grains, beans and oilseed meals used in poultry diet but the monoga...

The unique electrical, optical and thermal properties of black phosphorus have triggered the development of black phosphorus transistors as well as a wide range of other relevant applications. However, there are still challenges in understanding and modeling gated black phosphorus, among which the exploration of quantum capacitance is crucial. Understanding quantum capacitance requires specifie...

A hydroponic trial was carried out to investigate the effect of molybdenum (Mo) on uptake of phosphorus (P) in different rice cultivars. The experiment was conducted using a randomized complete-block design, with a split-plot arrangement of treatments and three replications. Four rates of Mo (0, 0.01, 0.1 and 1 mg L) and five cultivars (MR219, HASHEMI, MR232, FAJRE and MR253) provided the main ...

The story of phosphorus began with the search for the philosopher’s stone, and centuries later the critical role of phosphorus in soil fertility and crop growth was highlighted. Eventually, phosphorus was implicated in the global environmental challenge of eutrophication. Now, we are on the brink of yet another emerging chapter in the story: global phosphorus scarcity linked to food security. T...
