It was found that, in the presence of mannitol, the yield of SSB in N 2 saturated DNA solution was larger than that in air saturated solution so that the oxygen enhancement ratio (OER) of SSB became smaller than 1, which indicates the appearance of reverse oxygen effect of DNA SSB.

We expand HS model s hypothesis, consider constrain of short sale and contrarian trader s effect, build Momentum and Contrarian Effect Model under Constrain of Short Sale, which clearly characterizes stock price s movement track affected by positive and negative news and directly describes momentum and contrarian effect s extent affected by news watchers and trend traders.

However ,the discovery of momentum effect and contrarian effect poses great challenge to the above hypothesis .

At higher strain rates,both alloys display a tendency towards negative strain rate effect.

Treatment of wastewater during cornstarch production by UASB-contact biological oxidation combined processes;

According to the pilot test study using anoxic UASB reactor to treat mine domestic wastewater,the reliable basic parameter is supplied for industrialized application.

Using the spontaneous domains backswitching and domain side-grown effects,we can explain the mechanism of the submicron domains evolution.
