I don't know by whom you are employed,i only know that i recieved several letters for A and B.since you are working for Mr. hanley,i sincerely tell you that if you lose both A and B,there will be reasons for Mrhanleyto regret:you would have to buy it at a much higher price if it were bought by another ivesgating company;it would mean a great trouble if the fans got it;it would be a greater touble it you rivals got it.so i don't want you to lose this,and if you bought this, there would be great benefits:eg.if you cultivate the market in china, there will be many opportunities for you ,because this kind of companies are too few in china, your stock will be hot.

生活小百科网：『我也不知道你受雇于谁，我只知道我这来了几封购买A和B的信件，既然你受雇于hanley先生，我诚恳的告诉你失掉A和B，有几种原因会让hanley先生后悔的，如果让投资公司购买到你以后得花更高的代价，如果让此歌迷得到以后购买也许会很麻烦的，如果你让竞争对手得到的话你就会很糟糕的，我也不想你失去此A和B，如果你购买的话会产生很好的效果，如宣布开阔中国的市场，你就会带来更多的机运，因为中国这方面的公司实在太少了，你的股票也会大涨。

Polymorphisms in FSHB gene and association with egg production traits The SSCP detection of PCR products showed that FSHβpro site was polymorphismic in two population. Six nucleotide variation at G-494A, T-470A, A-464G,-450A insertion, A-405G and A-361G,were identified in promotor region of TaiHu chicken;Three nucleotide variation at A-464G,-450A insertion, A-405G,were identified in promotor region of blue eggshell chicken,three genotype.

FSHβ基因多态性与产蛋性状关系 FSHβ基因5'调控区和外显子3经PCR-SSCP检测发现，两个鸡群在FSHβpro位点都有多态，太湖鸡发现6处碱基差异，分别是：G-494A，T-470A，A-464G，-450插入碱基A，A-405G，A-361G；而绿壳蛋鸡在该位点有3处突变，分别是A-464G，-450插入碱基A，A-405G，有3种基因型。

T-Group and S-Group are two important types of operation group. To preserve T-Groups in operational transformation new algorithms are developed based on the REDUCE approach, and some explanations and examples of the correctness of the proposed algorithms are also given. We also give a strategy to preserve S-Group in REDUCE approach.
