STATEMENT OF PROBLEM Unlike screw-retention type, fixture-abutment retention in Locking taper connection depends on frictional force so it has possibility of abutment to sink. PURPOSE In this study, Bicon® Implant System, one of the conical internal connection implant system, was used with applying loading force to the abutments connected to the fixture. Then the amount of sinking was measure...

-The size distribution of pelagic producers and the size and trophic position of consumers determine the composition and magnitude of sinking fluxes from the surface communities in a simple model of oceanic food webs. Picoplankton, the dominant producers in the model, contribute little to the sinking material, due primarily to the large number of trophic steps between picoplankton and the consu...

Phytoplankton require light for photosynthesis. Yet, most phytoplankton species are heavier than water and therefore sink. How can these sinking species persist? Somehow, the answer should lie in the turbulent motion that redisperses sinking phytoplankton over the vertical water column. Here, we show, using a reaction-advection-diffusion equation of light-limited phytoplankton, that there is a ...

The abundance and sinking of particulate black carbon (PBC) were examined for the first time in the western Arctic and Subarctic Oceans. In the central Arctic Ocean, high PBC concentrations with a mean of 0.021 ± 0.016 μmol L(-1) were observed in the marginal ice zone (MIZ). A number of parameters, including temperature, salinity and (234)Th/(238)U ratios, indicated that both the rapid release ...

In reflecting on events of considerable significance, it is commonplace to remark that ‘it hasn’t sunk in yet’ or ‘it’s still sinking in’. Such talk sometimes associated with things seeming unreal, surreal, unfathomable, somehow impossible. this paper, I develop an account what these experiences consist of. First all, suggest they involve explicitly acknowledging the reality one’s situation, wh...

Y ou are doing a breast reduction. You have chosen a vertical flap and inverted T incision. You like the vertical reduction and medial pedicle because there is a shorter incision , but you think there will be too much skin excess, so it will be better to excise it now. For some reason, every time you do the inferior pedicle the base of the pedicle becomes thin and narrow. This worries you. You ...
