20130143249 | METHOD FOR DETERMINING PECTIN CONTENT IN PLANT SAMPLE - Disclosed is a method for determining pectin content in a plant sample, comprising the following steps: 1) adding an acidic alcohol solution to the plant sample, then heating the resulting mixture to reflux in a water bath, followed by a first filtration; 2) soaking the filtered residue obtained from the first filtration with an acidic solution, then heating the resulting mixture to reflux in a water bath, followed by a second filtration, then bringing to volume after cooling, obtaining filtrate for later use; 3) adding an acetic acid/sodium acetate buffer solution to treat the filtered residue obtained from the second filtration, then adding a pectinase solution and heating the resulting mixture under vibration in a water bath, followed by a third filtration to obtain a filtrate for later use; 4) sequentially adding an acetic acid/sodium acetate buffer solution and a pectinase solution to the filtrate obtained in step 2) and heating the resulting mixture under vibration in a water bath to obtain an enzymatic hydrolysate, then adding the filtrate obtained in step 3) to the enzymatic hydrolysate followed by bringing to volume, obtaining a test solution; and 5) drawing the test solution into a continuous flow analyzer to perform analysis. The method disclosed has the advantage of providing accurate analysis results. | 06-06-2013 |

20130191092 | METHOD FOR CALCULATING PRIMARY TIME CONSTANT OF POWER GRID - A method for calculating a primary time constant of a power grid. It comprises the steps of: establishing an electromechanical transient model of the power grid using the widely used power system analysis software package (PSASP) according to the actual power grid parameters and network topology; establishing an electromagnetic transient model under PASAP using the actual power grid parameters for a site which requires the calculation of the primary time constant of the power grid, and setting a ground short circuit fault at the site; obtaining a transient short circuit current of the short circuit point of the power grid using a hybrid simulation method of the electromechanical and electromagnetic transient models; filtering out a periodic component in the transient short circuit current to obtain a non-periodic component attenuated with time, and finding the attenuation time constant of the non-periodic component which is the primary time constant of the power grid. | 07-25-2013 |

20150161805 | Methods and Systems for Transitioning Between Arbitrary Shapes - Various arrangements for transitioning between data visualizations are presented. A first and second general path may be determined that define a first and second shape, respectively. A plurality of pairs of drawing commands may be created such that each pair of the plurality of pairs of drawing commands includes a first drawing command from the first general path and a second drawing command from the second general path. The plurality of pairs of drawing commands may be modified such that each pair of the plurality of pairs of drawing commands includes a single type of drawing command. A visual transition may be output for presentation between the first shape and the second shape using the modified plurality of pairs of drawing commands. | 06-11-2015 |
