These tests show that: 1. suction decreases with the increase of the water saturation in the chalk; 2. stress variants proposed are available for describing the stress state of the unsaturated chalk; 3. preconsolidation pressure increases with suction, while the effects of suction on the compressibility coefficients λ and κ are not evident; 4. as usual unsaturated soils, the permeability to oil of chalk increases with the suction; 5. yield strength of the chalk behaves with volumetric strain hardening; 6. cohesive behaviour of the chalk is related to the stress level, and relation between time-dependent deformation and logt is linear; 7. cohesion of the chalk decreases with the increase of the suction, while the elastic stiffness and the cohesion coefficient increase; 8. strength and elastic modulus increase with the strain rate, while the strain at the peak strength decreases with the increase of the strain rate.

Reactive oxygen species causing DNA oxidative damage comes from two kinds of ways:one is from cellular normal physiological metabolism;the other is from outer environment.Redox-sensitive green fluorescent protein was expressed in Saccharomyces cerevisiae.Recombinant cells were evaluated in monitoring the changes in the redox state of living cells when challenged with toxicologically relevant metal ions NaAsO_2 or Pb(NO_3)_2 by measuring emission intensity at 510 nm with a Hitachi F6500 fluorescence spectrophotometer,roGFP expressed in yeast responded not only to typical membrane-permeant oxidants H_2O_2 and reductants DTT,but also to toxicological metal ion-induced intracellular redox changes in a dose-dependent manner.Moreover,exposure of yeast cells to NaAsO_2 or Pb(NO_3)_2 at concentrations that induced redox changes reported by roGFP caused up to 2～3 fold increases in DNA mutation frequency.This mutagenic effect was largely caused by oxidative stress since blocking the production of hydryl radicals with thiourea significantly reduced the mutation rate as well as delayed the cell death.

本文將對氧化還原狀態(tài)變化敏感的綠色熒光蛋白roGFP1-R12，在酵母細胞中實現了多拷貝強表達午夜日韩福在线播放；熒光掃描經強氧化劑H_2O_2和還原劑DTT以及環(huán)境中重金屬NaAsO_2或Pb(NO_3)_2處理后的酵母細胞懸液欧美喷浆，測定510 nm處的熒光發(fā)射強度結果顯示，表達的綠色熒光蛋白對氧化還原水平敏感，且在510 nm處的熒光強度與一定的重金屬濃度呈正相關免费可以直接看黄视频网站，即roGFP1-R12在510nm處的熒光發(fā)射值隨重金屬濃度的增高而增強www.9色色，從而說明重金屬對細胞的毒性在一定程度上很可能是通過破壞細胞內的氧化還原平衡發(fā)生作用；同時通過該綠色熒光蛋白對胞內氧化還原狀態(tài)變化的響應情況可以來實時檢測環(huán)境中的重金屬在线无码国产观看播放网址；遺傳學的點突變頻率及致死率實驗數據表明久久久精品合，重金屬能導致菌體的點突變頻率和致死率升高，且活性氧的清除劑巰基脲能明顯降低這種點突變和致死率2019年一级黄片，說明由重金屬引發(fā)的這種點突變和致死效應在很大程度上是依賴于重金屬對細胞誘導產生的氧化脅迫国产一级α爱免费视频。
