  • Microgranular Water-soluble Fertilizer Co-produced from Potassium Nitrate by Tower Melt and Method of Preparing the Same
    Publication number: 20180339948
    Abstract: Disclosed are a microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt and a method of preparing the same, which relate to the technical field of production of water-soluble fertilizers. The microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt is prepared from potassium nitrate concentrate, urea, industrial monoammonium phosphate, water-soluble ammonium polyphosphate, potassium sulfate, EDTA-Fe, EDTA-Zn, EDTA-Mn, boric acid and ammonium heptamolybdate. The microgranular water-soluble fertilizer product co-produced from potassium nitrate by tower melt has balanced and stable nutrients. The product is microgranular, has a smooth appearance, is less susceptible to agglomeration, is easy to be absorbed and utilized by crops, and contains a full range of nutrients. In addition, the product is produced by a process employing fully automatic dispensing equipment, which mainly integrates “dispensing, mixing and packaging” and is fully automated.

  • Method and apparatus for optimization of collimator angles in intensity modulated radiation therapy treatment
    Publication number: 20050123098
    Abstract: A method and apparatus to determine an optimum collimator angle of a multi-leaf collimator having an opening and multiple leaf pairs for closing portions of the opening to form a radiation beam arrangement having multiple radiation beam segments. The method and apparatus include application of a cost function to determine a collimator angle which provides for delivery efficiency and target conformity. The user can preferentially either selectively enhance delivery efficiency of the radiation beam arrangement, reducing a number of radiation beam segments and reducing a number of radiation beam monitor units required for delivery of the desired prescription, or selectively enhance conformity of the radiation beam arrangement to a target shape. The optimum collimator angle is then used for delivery of an optimized radiation beam arrangement to a patient by a radiation delivery device.
