Isolated cells are MSCs, with the property of stem cells. The third and fifth passage cells are pure, with strong reproductive capability.

If the other party fails to perform its obligation in the contract within the time agreed upon in this Contract,and fails to eliminate or remedy such breach within15 days following the receipt of the notice thereof from the non-breaching party and still again fails to perfrom the contract within the period of time allowed for delayed performance,in such case the non-breaching party shall be entitled to rescind the contract by a wirtten notice to the defaulting party and still have the right to claim damages from defaulting party.

如果任何一方在合同履行期间没有履行其合同所规定的义务，且在非违约方提出通知内15天没有及时终止违约行为，且在允许延迟履行的时间内没有继续履行合同义务，在这样的情况下，非违约方有权以书面通知的形式通知违约方终止合同，并有权由此产生的损失向违约方索赔。

A new switching scheme to the gain of variable structure control signals is proposed. The following important open problems in standard VS-MRAC and MRAC are solved by using the scheme: 1 . a prespecified transient and steady-state performance index for tracking error can be achieved without requiring any information about the plant high frequency gain sign when relative degree of modelled part of plant is one, and 2 . it is shown that as long as the performance indexes are guaranteed for the auxiliary errors, each of which in dynamics is a sub-system with relative degree one, the tracing error will converge to a small residual set in a prespecified transient time when relative degree of modelled part of plant is greater than one.

提出了一种控制增益可切换的变结构自适应律，解决了如下变结构模型参考自适应控制（包括基于调参律的模型参考自适应控制）理论研究中长期没有解决的问题：当对象建模部分相对阶为1、高频增益符号未知且存在非线性输入扰动和未建模动态等情况下，系统跟踪误差可满足预先给定的动态和稳态性能指标；当对象建模部分相对阶大于1且存在非线性输入扰动和未建模动态时，可保证系统跟踪误差在预先给定的过渡过程时间内收敛到一个残差集中； 5。

B: To H model blade tip, the film cooling effectiveness was controlled by main flow Reynold number, and has little relation with blow ration, which is different from normal film cooling.

且主流流速大时，冷却效率变低，且增大气膜吹风比对提高冷却效率不很明显，这一点不同于其它简单结构的气膜冷却。

Ureg such that =; E (the ideal extension of a ring R by its ideal I) is an exchange ring if and only if R and I are both exchange.

一个一般环I是exchange的当且仅当对它的任意理想L以及=2∈I/L，存在w∈r.ureg使得=；E(环R通过它的理想I生成的理想扩张)是一个exchange环当且仅当R和I都是exchange环。

I give everybody to introduce some behind-the-scenes plotting, the strawberry use also to calculate few, fruits and so on apple, peach, grape, banana, so long as shifts to an earlier time going on the market, and has the appearance, many are depending on the ripener accelerate ripening, I chats with a relational good commerce when she tells me to say her to stock with goods when only looked that the strawberry and the freshness, is a price again, but also which kind has, does not have the environmental damage she not to ask, the customer mostly also only cares about this difference, even if because the present price has fallen half, also the very few some people buy oneself to eat, majority of has bought the attireGives a present to the gift box.

我给大家介绍一些黑幕，关于草莓，我跟一位关系不错的商贩聊天时她就告诉我说她进货时只看草莓的个头和新鲜度，再就是价钱，还有在哪种的、是不是无公害她都不问，顾客大多也都只关心这两样，因为即使现在价格降了一半，也很少有人买回家自己吃，大部分都是买了装到礼盒中送礼。草莓用催熟剂还算少的，苹果、桃子、葡萄、香蕉等水果，只要是提早上市且有卖相的，多是靠催熟剂催熟的，且催熟剂用的量更大，我提醒大家注意，换季水果少买。

Generally, instrumental rumination helped to reduce negative mood, emotional-focused rumination worsened negative mood, and meaning-searching rumination increased the duration of negative mood. Moreover, in the period of severely and long-term negative mood status, instrumental rumination seemed to maintain the duration of positive mood, emotional-focused rumination still worsened negative mood, and meaning-searching rumination seemed to prolong the duration of negative mood. Besides, in the period of negative mood episode, instrumental ruminative had no effect on mood fluctuation, emotional-focused rumination deteriorated and extended negative mood, and meaning-searching rumination had harmful effect on the negative mood but still had borderline effect on the positive mood.

整体平均来说，功用性反刍有助於负向情绪的缓解、情绪焦点反刍会增强负向情绪感受、意义寻找反刍则是增加负向情绪维持的时间；若当天处在长期又严重情绪不佳日子中时，功用性反刍似有维持正向情绪的效用、情绪焦点反刍则是恶化当天的负向情绪强度、意义寻找反刍则有延长当天负向情绪时间的趋势；若连续处在长期且严重情绪不佳的日子中，功用性反刍对情绪变化并无影响、情绪焦点反刍则是延长且恶化此时期的负向情绪状态、而意义寻找反刍不但会影响负向情绪的状态，似也会有助於此时期的正向情绪状态。

These results imply that although both MTs and ZnT-1 can attenuate the zinc toxicity, they may play different roles at different phases. ZnT-1 enhance the efflux of zinc prior to the sequesteration by MTs. The action of ZnT-1 may be durable, but the role of MTs may be satiable.

虽然神经元可通过增加ZnT-1和MT的表达来应对高锌冲击，但两者的保护作用不同，ZnT-1外排作用发生在前且具有持续性，MT的络合作用发生在后且会饱和。

Akuei wants us to be serious, I still believed in my mind,"Whenever you go out, it must be fun, no matter scariness in your heart or other people's advice, I must be happy and make it my way to play, and I'll turn it into fun in my heart."

，连ㄚ贵老师都要我们严肃且认真，我还是坚决我出去别人一定破不了的道理：「出去ㄧ定都好玩、不管心理负担或别人劝告，我一定放轻松且照自己的方式享受活动的任何一部分，把它转为我心目中的好玩。

All 5 patients of benign polyp were found to have excellent effect after Nd-YAG laser therapy, and so for, there was no recurrence. Two (esophageal cancer 1 and rectal cancer 1) of 19 patients of G-I cancer had excellent results with tumor size reduced over 90% and endoscope could pass through the stenotic area smoothly after Nd-YAG laser treatment. Six (esophageal cancer 2, gastric cancer 4) of them had good results with tumor size reduced 50-90% and patient could take semiliquid food after laser management. Eight patients (esophageal cancer 2, gastric cancer 4, rectal cancer 2) had fair effects with tumor size reduced less than 50%, but the oral intake or stool passage was improved. Three patients (15.8%) refused further endoscopy and laser management because of poor tolerance.

这5例良性息肉经雷射治疗后，肿瘤完全消失且目前无后发现象。19位恶性癌中，经Nd-YAG雷射治疗后，效果极佳（肿瘤大小减少90%以上，内视镜可通过肿瘤狭窄处）者2例（食道癌及直肠癌各1；效果佳（肿瘤大小减少50~90%，且病人可进食半流体食物）者6例（食道癌2，胃癌4）；效果尚可（肿瘤大小减少50%以下，但饮食进步或排便较过去进步）者8例（食道癌2，胃癌4，直肠癌2；3例患者(15.8%)因不能忍受内视镜及雷射治疗之痛苦，拒绝进一步的治疗而失败。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
