A Fulx Difference Splitting (FDS) scheme was used in a 2D depth-averagedflow-pollutant model. Within the framework of the Finite Volume Method (FVM) a 2D simulation wastransferred into solving a series of local ID problems based on the rotational invariance propertyof the flux. The FDS scheme was employed to estimate the normal numerical flux of variablesincluding water mass, momentum and pollutant concentration across the interface between cells. Thescheme was checked with exact solutions and verified by observations in the Nantong reach of theYangtze River. Calculated results well match both exact solutions and observations.

Polygrits of alumina(***(?) of 3M) also out perform by far glassy grits(*** alumina).For diamond superabrasives,micron polygrits formed by shock waves may polish as fast as mono grits of the same size,but without causing as much scratches due to the presence of smaller sintered *** improved performance of poly grits is attributed to their ability to micro chipping that renews the sharp cutting corners from time to *** contrast,mono grits tend to round off at low cutting force or macro fracture at high cutting force,so they may lose the cutting ability rapidly.

With the relentless densification of interconnected circuitry dictated by Moore’ s Law,the CMP manufacture of such delicate wafers requires the significant reduction of polishing pressure of integrated circuits,not only globally,but also locally on every tip of the pad *** diamond disks used for dressing the polyurethane pads cannot produce asperities to achieve such uniformity.A new design of diamond disk was fabricated by casting diamond film on a silicon wafer that contains patterned etching pits. This silicon mold was subsequently removed by dissolution in a hydroxide *** diamond film followed the profile of the etching pits on silicon to form pyramids of identical in size and *** variation of their tip heights was in microns of single digit that was about one order of magnitude smaller than conventional diamond disks for CMP ***,the diamond film contained no metal that might contaminate the circuits on polished wafer during a CMP *** continuous diamond film could resist any corrosive attack by slurry of acid or ***,in-situ dressing during CMP is possible that may improve wafer uniformity and production *** ideal diamond disk(IDD) is designed for the future manufacture of advanced semiconductor chips with node sizes of 32 nm or smaller.

A 42-year-old man presented with a two-year history of progressive dysphagia and hoarseness. Esophagogram and endoscopy revealed submucosal mass effect on the upper esophagus. Computed tomography and magnetic resonance imaging revealed an elongated mass in the retrotracheal region of the lower neck with extension to the posterior mediastinum. Partial tumor resection and histopathological evaluation revealed a WHO type B2 thymoma. Adjuvant radiation and chemotherapy were subsequently administered resulting in complete tumor regression. To our knowledge, this is the first report of ectopic retrotracheal thymoma with clinical and imaging manifestations mimicking those for esophageal submucosal tumor.
