Tidal current asymmetry, an important factor for waterborne substance transport, is strongly affected by the changing shoreline. Lingding Bay (LDB), located in center of Guangdong-Hong Kong-Macao Greater Area, has suffered great shoreline changes since 1970s. A well-validated numerical model built to investigate how impacts tidal which quantified skewness parameter. Two types asymmetries, flow ...

Sulphosalts in the system AgSbS2-AgAsS2 have been experimentally investigated using dry methods. The solid solutions which form between ?-miargyrite and smithite have different structures. The EPMA data for the solid solution series show that there is an inverse relation between Sb and As. The cell parameters of the solid solution between ?-miargyrite and smithite increase up to about 50% of...

Let S2 be the 2-dimensional unit sphere and let Jα denote the nonlinear functional on the Sobolev space H1,2(S2) defined by Jα(u) = α 4 ∫

In (4) Young investigates the representation in terms of his exact seminormal units m^ of substitutional expressions which are unchanged on premultiplication by any permutation of a given set of consecutive letters, or which are changed in sign on premultiplication by an odd permutation of those letters. He illustrates his results by deducing the forms of the matrices representing the positive ...

Understanding salinity and fertilizer interaction is of great importance to improve crop production use efficiency in saline areas. To evaluate the interactive effects different soil levels nitrogen (N) applications rates on sunflower photosynthetic characteristics N uptake efficiency, a two-year field experiment was conducted Hetao Irrigation District, China. The consisted three initial (IS) e...

PURPOSE The purpose of this research was to analyze cagA and vacA genotypes status in H. pylori isolates and relationship with clinical outcomes. METHODS Gastric biopsy specimens were cultured for H. pylori isolation and cagA and vacA genes were detected in these isolates. Data were collected and the results were analyzed using χ2 and Fishers exact tests by SPSS software version. 16. RESULT...
