Ocean surface winds observed by the Quick scatterometer(QuiksCAT) satellite prior to the geneses of 36 tropical cy-clones(TCs) in the south China.s.a.s.s) are investigated in this paper. The results show that there are areas with negative mean horizontal divergence around the TC genesis locations three da.s.prior to TC formation. The divergence term [-(f+ζ)(u/x+v/y) ] in the vorticity equation is calculated based upon the QuiksCAT ocean surface wind data. The calculated mean divergence term is about 10.3 times the mean relative vorticity increase rate around the TC genesis position one day prior to TC genesis,which shows the important contributions of the divergence term to the vorticity increase prior to TC formation. It is suggested that criteria related with the divergence and divergence term be applied in early detections of tropical cyclogenesis using the QuiksCAT satellite data.

The device performance of Cds/CdTe solar cells largely depends on not only the back ohmic contact, but a.s. the conformality of Cd s window layer coating. In order to reduce the light a.s.rption loss in Cd s, the Cd s thickness is usually less than 100 nm. However, pinholes in Cd s and non-conformal coverage of Cd s on tra.s.arent conducting oxide layer will ca.s. shunting thus leading to device performance degradation and failure. In this paper, low-temperature and low-cost fabrication methods, i.e., chemical bath deposition and electrochemical deposition, were used to deposit Cd s and Cd Te, respectively. It was found that the yield of device was around 20 % due to shunting. In order to alleviate this problem, a compact layer of TiO2 was inserted between the fluorine-doped tin oxide and Cd s as a buffer layer. The thickness effect of TiO2 was studied and showed that devices with thin(20 nm thickness) TiO2 performed better than the counterparts with thick layers. It was discovered that device yield improved to 80 % and stability in air substantially improved with TiO2 layer.

The compaction of particulate materia.s.to form tablets is increasingly employed as a final dosage form for functional products due to its simplicity and low cost. However, the functionality of some products may be impaired due to the high compression pressures required. The general aim of the current study is to understand the relationship between the mechanical properties of single feed particles （〈 100μm） and their compaction behaviour in order to produce tablets at low compression pressure with acceptable strength. The materia.s.studied were pharmaceutical excipients, comprising three enteric polymer particles and three different powders in the form of agglomerates. The mechanical properties of the individual particles or agglomerates were determined by a micromanipulation technique. The samples were a.s. compacted in cylindrical tableting dies. It was observed that there was a.s.rong correlation between the forces required to ca.s. the fracture of the single particles and those derived from the compaction measurements as determined using an existing analysis.

For three weeks in October 2009, the U.s. Department of Energy hosted the solar Decathlon Competition in which 20 tea.s.of college and university students competed to design, build, and operate their own version of a.s.lar-powered house. Team North＇s mission was to deliver North House, a compelling, marketable solar powered home for people with active lifestyles, while building Canada.s.next generation of leaders in sustainable engineering, business and design. This paper dea.s.with a.s.lar-a.s.sted space heating system that was studied as a potential design for the competition. Among several other conclusions, it was found that using a.s.lar-a.s.sted in-floor heating system can decrease the energy consumption to only 8% of the case without the in-floor loop.

This paper analyzes developments and trends related to China.s.outward direct and financial investments by examining Chinese firms＇ overseas acquisitions, China.s.holdings of Us Treasury securities, and the recently formally launched Qualified Domestic Institutional Investor progra.s. strategies should be developed to reach optimal decisions for both direct and por（folio investments. We argue that China.s.ould have a longer-term view for both direct and portfolio investments, enabling China to become the leader in Asia while maintaining its sustainable growth objective. China.s.ould invest heavily in the development of the Asian bond market and the Asian Currency Fund when making both por（folio and direct investment decisions.
