A protecting-group-free enantioselective tandem allylic substitution of o-phenylenediamines and o-aminophenols is realized for the first time with a Pd-WingPhos catalyst,providing expedient access to a series of chiral vinylsubstituted heterocycles in excellent ee and yields under mild reaction conditions.The protocol is applied successfully to the synthesis of a cholesteryl ester transfer protein(CETP)inhibitor.

Reaction zone characteristics were studied using hydroxy radical planar laser-induced fluorescence （OH-PLIF） technique for a counter-flow preheated （CH4＋N2）/（Air＋N2） diluted diffusion flames. The effects of preheat temperature and dilute ratio on the reaction zone characteristics were investigated by demonstrating the OH intensity distribution and reaction zone thickness from OH-PLIF images. Under the experimental conditions of constant cold flow velocity, the results show that the OH intensity and reaction zone thickness decrease with the increase of dilute ratio at constant preheat temperature and increase with preheat temperature at fixed dilute ratio. The OH maximum intensity shifts towards the ＂lean＂ side of counter flow at constant preheat temperature, and it shifts towards the fuel side with the increase of dilute ratio of fuel stream and towards the oxidizer side with the increase of dilute ratio of oxidizer stream respectively. The feasibility of OH as a reaction zone marker in this diluted combustion is verified further. The variation of diffusion and chemical reaction rate of reactants due to preheat and dilution contributes to the reaction zone characteristics simultaneously. The effect of strain on the flame reaction zone should be included in the future work.

1932年Ruska发明了以电子束为光源的透射电子显微镜（TEM），电子束的波长要比可见光和紫外光短得多，并且电子束的波长与发射电子束的电压平方根成反比，也就是说电压越高波长越短，目前TEM的分辨力可达0．2nm。

薄储层在马来盆地日益成为海上勘探的目标。这些储层表现为垂向呈非均质性且包括领导储层流动特性。本文描述了确定这种储层特性的实时高分辨率地层评价和地层测试方法。薄储层的地层评价有以下几个目的：①判断可能的油气层；②通过地层测试和取样确定产能和流体类型；③计算纯产层厚度及误差范围。由于地层几何形态和岩性的原因，所以评价过程比较复杂。储层厚度通常小于地层评价测井仪的分辨率。储层岩性为粉砂，呈细粒结构，所以要求有高质量的井眼电阻率图像才能确定其几何形态。探井为评价储层的勘探前景提供了最好的机会，但因为操作的限制和经济的限制，不可能对每一个可能储层都进行取心或测试。因此，实时评价方法必须确切地判断勘探远景，以便进行下一步测试。本文要描述的实时地层评价包括以下几个步骤：（1）针对以下参数进行现场岩石物性分析：①孔隙度；②粘土、矿物和流体的体积；③根据gR能谱元素产额、核及声波孔隙度以及阵列电阻率测井资料得到的渗透率；（2）识别薄层并通过电阻率成像仪计算砂层总有效厚度；（3）验证现场岩石物性分析结果以及开始读取测井数据后2h之内的井眼图像，并设计电缆测试和取样程序。用一种模块式电缆地层测试器测量储层岩石的现场压力并建立流体梯度，判断流体界面。除此之外，通过预测试分析估算局部地层渗透率，并来验证用地层评价方法判断薄层的产能。

Background:Familial hypomagnesemia with hypercalciuria and nephrocalcinosis(FHHNC)is an autosomal recessive tubular disease caused by mutations in the CLDN16 or CLDN19 gene.Previous studies using microsatellite markers flanking the CLDN19 locus estimated that p.g20D(c.59g>A),a recurrent mutation in Spanish families,is a founder mutation.In the present study,we assessed the haplotype of Spanish patients using single nucleotide polymorphisms(SNPs).Methods:Twenty-seven FHHNC patients were included in this study.We analyzed four SNPs located in CLDN19 introns 3 and 4 by polymerase chain reaction amplification and DNA sequencing.Results:Three new patients with homozygous p.g20D were identified.The SNP genotyping analysis showed that alleles carrying this mutation shared a common SNP haplotype.Conclusions:Our findings suggest the existence of a founder effect responsible for FHHNC in our cohort.Testing for the presence of mutation p.g20D should be the first genetic screening in Spanish patients.

In this study, we apply geochemical and statistical analyses to evaluate the source rocks and kerogen type of Cretaceous sediments from the Cote d’Ivoire sedimentary basin. The geochemical analysis includes pyrolysis data such as total organic carbon (TOC%), generation source potential (S2) and hydrogen index (HI). The results of the cluster analysis separated the source rocks in the study area into two main groups. 1) Source rocks characterized by HI > 300 (mg/g), TOC from 1.76% to 3.19% by weight, and S2 from 6.55 to 14.46 (mg/g), indicating good to excellent source rocks with type II kerogen and are capable of generating oil. 2) Source rocks characterized by HI between 200 and 300 (mg/g), TOC from 1.6 to 2.02 wt%, and S2 from 3.45 to 5.36 (mg/g) indicating medium to good source rocks with type II-III kerogen and capable of generating a mixture of oil and gas.

全面译解人类基因组的计划需要建立高分辨率的遗传图,需要确定构成基因组的数以万计DNA片段的有序集(称为“物理图谱”),需要测定构成人类基因组的30亿个核苷酸的准确排列顺序。目前运用的或正在研究的实验策略是依靠计算机科学的各个方面:自动化、模拟、计算、计划管理、数据库等。这一庞大计划虽属生物学范畴,但其成功首先要靠所用信息技术的质量,或许还要靠数据库和数据表达领域的新概念的出现。

JUNO is a multi-purpose neutrino observatory under construction in the south of China.This publication presents new sensitivity estimates for the measurement of the △m_(31)^(2),△m_(21)^(2),sin^(2)θ_(12),and sin^(2)θ_(13) oscillation parameters using reactor antineutrinos,which is one of the primary physics goals of the experiment.The sensitivities are obtained using the best knowledge available to date on the location and overburden of the experimental site,the nuclear reactors in the surrounding area and beyond,the detector response uncertainties,and the reactor antineutrino spectral shape constraints expected from the TAO satellite detector.It is found that the △m_(21)^(2) and sin^(2)θ_(12) oscillation parameters will be determined to 0.5%precision or better in six years of data collection.In the same period,the △m_(31)^(2) parameter will be determined to about 0.2%precision for each mass ordering hypothesis.The new precision represents approximately an order of magnitude improvement over existing constraints for these three parameters.
