Volatilization of ammonia (NH3) from animal manure is a major pathway for nitrogen (N) losses that cause eutrophication, acidification, and other environmental hazards. In this study, the effect of alternative techniques of manure treatment (aeration, separation, addition of peat) and application (broadcast spreading, band spreading, injection, incorporation by harrowing) on NH3 emissions in th...

Three different commercially available molasses-based supplements were evaluated for their effects on the performance of preconditioning calves during the fall of 2002. One hundred and forty calves (mean body weight, 465 lb) were randomly allotted to one of four treatments. Treatments offered were: 1) 16% crude protein fortified molasses slurry, 2) 16% crude protein fortified molasses slurry pl...

A Nano-Encapsulated Phase-Change Material (NEPCM) suspension is made of nanoparticles containing a Phase Change in their core and dispersed fluid. These particles can contribute to thermal energy storage heat transfer by latent phase change as moving with the host Thus, such novel nanoliquids are promising for applications waste recovery systems. In present research, mixed convection NEPCM susp...

Latent heat thermal energy storage systems (LHTES) are useful for solar and many other applications, but there is an issue with phase change materials (PCMs) having low conductivity. This can be enhanced fins, metal foam, pipes, multiple PCMs, nanoparticles (NPs). paper reviews nano-enhanced PCM (NePCM) alone additional enhancements. Low, middle, high temperature classified, the achievements li...

Hydrate plugging is the major challenge in the flow assurance of deep-sea pipelines. For water-in-oil emulsions, this risk could be significantly reduced with the addition of anti-agglomerants (AAs). Hydrates often form from water-in-oil emulsions and the measurement of emulsion and slurry viscosity constitutes the basis for the application of hydrate slurry flow technology. In this work, using...

Co-digestion of cattle slurry and maize has been shown to have benefits for both, improving the biogas yield of the slurry and stability of digestion of the maize. The effect of increasing the total loading rate from 3 to 6 g VS l(-1) day(-1) on the co-digestion of cattle slurry and maize, mixed at equal volatile solids volumes, was investigated in laboratory-scale continuously stirred digester...

nt matter & 2007 IAgrE. emseng.2007.03.037 hor. : [email protected] Research on the incidence and effectiveness of natural crusting on slurry storage as a means of ammonia emission abatement was undertaken in studies at farm-scale, pilotscale and on a small-scale. At the farm-scale, slurry crusting was found to be commonplace across a large proportion (ca 80%) of slurry storage facilities, d...

This study investigated the effectiveness of vegetated buffer strips for removing contaminants in runoff from grassed plots (slope 15%) after application of cattle slurry. Plots (8 x 8 m2 or 8 x 3 m2) received slurry or inorganic fertilizer, and then simulated rainfall (1, 7 and 21 days after slurry/fertilizer application); after each event, runoff and percolates were sampled at various distanc...

Animal manure is an important source of N for crop production. Part of the manure N is bound in organic compounds and must be mineralised in the soil before it can be utilised by plants. The composition of animal manure is influenced by the diet fed to the animal. We have studied the effects of pig and dairy cattle feed composition on the turnover and potential utilisation of manure N. Dairy co...

Although talc slurry pleurodesis is effective for control of malignant pleural effusions and recurrent pneumothorax, the mechanisms of pleurodesis remain incompletely defined. We instilled 70 mg/kg of sterile asbestos-free talc slurry into the pleural space of New Zealand white rabbits and studied the inflammatory response at 1, 2, 3, 7, 15, 30, 60, 90, and 120 days by observing pleural fluid a...
