Gas/water two-phase flow is widely encountered and of great importance in manufacture process and scientific researches, and recognition of its flow regimes is significant to the accurate measurement of its process parameters. Many groups have been working on the online recognition of flow regimes, ...
Results The 5.0 mm-BOZD OK, 6.2 mm-BOZD OK, and DISC groups exhibited significantly slower AL elongation than the SCL group. The proportion of slow progressors (AL elongation ≤ 0.18 mm/year) in the first three groups was 42%, 23%, and 29%, respectively. Furthermore, one-year ...
Three types of equipment from the previous CG R&D Center's evaluations, boom deflector, boom vane and oil spill Flow-Diverter, were further evaluated in the field exercises along with the Coast Guard's only pre-deployed Vessel Of Opportunity Skimming System (VOSS) in the inland rivers region....
Cells are sub-cultured once a week with split ratio 1:3 to 1:6 and expanded. The medium needed to be renewed once a week. Cells were rinsed briefly one time with 2 ml of fresh Trypsin/EDTA solution (0.25% trypsin with EDTA 4Na) and aspirated. Then 1.5 ml of Trypsin/EDTA was ...
Our promising results in embryos motivated us to ask if PEmbryo could be used to genetically engineer mice. Given that mice deficient for MMR (for example, mutations in Mlh1 and Pms2) are infertile45,46,47, an immediate concern was that transient expression of mMLH1dn could impact fertility...

The young microspore (YM) stage is the most sensitive period for wheat grain formation to abiotic stress. Shading stress during YM stage reduces grain yield mainly due to grain number decrease. However, the photosynthetic base for grain number decrease i
