A study was undertaken on drained and undrained 1 ha grassland lysimeters to assess the effectiveness of multiple novel tracing techniques in understanding how agricultural slurry waste moves from land to water. Artificial fluorescent particles designed to mimic the size and density of organic slurry particles were found to move off the grassland via inter-flow (surface + lateral through-flow) ...

Organic fluorescent nanofibrils were fabricated from a linear carbazole trimer and employed for expedient detection of nitroaromatic explosives (DNT and TNT) and highly volatile nitroaliphatic explosives (nitromethane).

High Energy Materials is a term that is used for explosives, propellants and pyrotechnics. Explosives are used for military applications. 5-Picrylamino-1,2,3,4-tetrazole(PAT) is an explosive substance. In this study the reactions of the 5-Picrylamino-1,2,3,4-tetrazole(PAT) with nanostructures of fullerene and boron nitride nano-cages in different conditions of temperature, with density function...

Excess crude protein (CP) in dairy cow diets is excreted mostly as urea nitrogen (N), which increases ammonia (NH) emissions from dairy farms and heightens human health and environmental concerns. Feeding less CP and more tannin to dairy cows may enhance feed N use and milk production, abate NH emissions, and conserve the fertilizer N value of manure. Lab-scale ventilated chambers were used to ...

NH3, CH4 and N2O emissions from dairy cattle and pig slurries were quantified. The effect of the following treatments was investigated: untreated covered slurry, mechanically separated slurry, anaerobically digested slurry, slurry covered with a layer of straw, and slurry aeration. Measurements were carried out with dairy cattle and with pig slurry, in winter and in summer. After storage, slurr...

Slurry, due to high microbiological contamination, requires hygienization before spreading. The agricultural usage of treated slurry has to guarantee biosafety. Therefore, constant monitoring of the slurry treatment process should be conducted. The use of Filter-Sandwich carriers seems to be a prospective solution. The aim of the research was to test whether Filter-Sandwich carriers influence t...

comaring the capability of photocatalyst nano zinc oxide process by two slurry and immobilized methods in dye acid orange 7 removal introduction everyday million liters of color wastewater are produced in different industries and cuases environmental problems. the textile industry significantly affects the environment, producing high volume of wastewater from water and chemicals used in process...

We measured the 229 nm absolute ultraviolet (UV) Raman cross-sections of the explosives trinitrotoluene (TNT), pentaerythritol tetranitrate (PETN), cyclotrimethylene-trinitramine (RDX), the chemically related nitroamine explosive HMX, and ammonium nitrate in solution. The 229 nm Raman cross-sections are 1000-fold greater than those excited in the near-infrared and visible spectral regions. Deep...

Land application of cattle slurry can result in incidental and chronic phosphorus (P) loss to waterbodies, leading to eutrophication. Chemical amendment of slurry has been proposed as a management practice, allowing slurry nutrients to remain available to plants whilst mitigating P losses in runoff. The effectiveness of amendments is well understood but their impacts on other loss pathways (so-...
