Pot experiments were carried out in a completely randomized design in the screenhouse of Faculty of Agriculture, South Valley University, Egypt, to evaluate the application effects of different organic wastes (sewage sludge, filter mud cake, compost, filter mud cake-compost mixture and sewage sludge-compost mixture) at different levels (5, 15 and 30 ton/fed. on the release and availability of N, P and K in three different soils (clay, calcareous sandy, and sandy soils). Corn plants followed by wheat plants were grown during two successive seasons of summer 2011 and winter of 2011/2012. Total Nitrogen (N), available phosphorus (P) and available potassium (K) in soils as well as plant dry matter and the uptake of these nutrients by plants were determined to evaluate the N, P and K released in the soil and their uptake by these plants. The application of these organic wastes at different levels showed significant increases in N, P and K that were released in the studied soils as well as plant dry matter yield and the uptake of these nutrients by corn and wheat plants. In general, use of these investigated organic wastes at the level of 30 ton/fed. in these studied soils gave the best results

The changes in physicochemical and structural properties of Ultra high pressure (UHP) gelatinized mung bean starch were investigated during 0 to 196 hours retrogradation process by using X–ray diffraction (XRD) and differential scanning calorimetry (DSC). XRD analysis showed that the UHP–gelatinizated granules regenerated its original C–type crystallinity structures after retrogradation. The swelling power and solubility of native starch were increased with the increase in the assay temperatures from 50–90 °C, while the changing trend of the retrogradated granules was more gradual over entire assay temperatures. In addition, retrogradated granules showed a progressive decrease in the light transmittance and an increase in the amount of resistant starch as the ageing time increased from 0 to 192 h. DSC analysis suggested a slight increase in the transition temperatures (To, Tp and Tc) and the retrogradation enthalpy as the storage time increased. In contrast no endothermic transition peak could be observed using DSC after storage of heat–gelatinized mung bean starch gel.
