Abstract. Slow-release fertilizers (SRFs) are developed, to halt the nutrient loss environment, either by coating urea or infusing in a hydrophobic material. SRFs reduces release that point where single application of fertilizer can meet demand plants. Diverse range materials have already been utilized produce SRFs, however several disadvantages such hydrophilicity, non-biodegradability and cry...
Abstract Urea-based multi-coated slow release fertilizer was produced using water hyacinth, humic substances, and chitosan, with rich in natural organic matter as a solvent. Elemental analysis showed that the nitrogen content of (FERT) around 20%. Swelling tests demonstrated effectiveness hyacinth crosslinker, which reduced permeability material. Leaching FERT released very low concentration am...
The rise in global population, urbanization, and desertification pushes the farming community toward intensive cropping to meet augmented food demands with consequent exhaustion of soil’s nutritional status fertility. In recent times, environmental pollution cost crop production have been enhanced due excessive inefficient use nitrogenous fertilizers. As an abatement strategy, seven different c...
Abstract We propose to develop, characterize and operate a superconducting undulator (SCU) afterburner consisting of 5 modules (1 module = 2 SCU coils m length 1 phase shifter) plus pre-series prototype at the SASE2 hard X-ray beamline European XFEL. This will produce an output in order 10 ph/pulse photon energies above 30 keV. The project is divided into production small-series modules. Centra...
This project assessed the extent to which modern technology (Vigil) can augment or substitute for direct staff intervention in nonacute late-evening and nighttime situations in a nursing home setting. Vigil was implemented for dementia residents of a special care unit (SCU) in a large nursing home. An SCU matched in terms of unit-wide case mix and cognition was used for comparison. Results show...
Evaluation is one of the hardest tasks in automatic text summarization. It is perhaps even harder to determine how much a particular component of a summarization system contributes to the success of the whole system. We examine how to evaluate the sentence ranking component using a corpus which has been partially labelled with Summary Content Units. To demonstrate this technique, we apply it to...
Nowadays exhaust emission control from internal combustion engines have become one of the most important challenges. Oxides of nitrogen (NO [email protected] x) are one of the major hazardous pollutants that come out from diesel engines. There are various techniques existing for NOx control but each techniques has its own advantages and disadvantages. Technologies available for NOx reductions e...
