测井曲线拐点在测井层序地层分析中的应用研究

在层序地层学研究中，层序界面的划分是基础和重要的环节，而利用测井资料分析可以进行层序界面划分和进行较长期基准面旋回识别。测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大（极小）值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。基于以上特点，提出利用测井曲线拐点进行层序界面划分的原理和方法，并结合岩心和录井资料，对白音查干凹陷达28井腾格尔组不同级次沉积旋回、地层垒积、旋回特征随沉积厚度变化特点和不同级次基准面旋回进行研究，最后得到该地层单井测井层序地层分析结果。

Free energy simulations of the HyHEL-10/HEL antibody-antigen complex

Free energy simulations are reported for the N31^L-D mutation,both in the HyHEL-10-HEL antibody-lysozyme complex and in theunliganded antibody, using the thermo-dynamic-cycle perturbationmethod. The present study suggests that the mutation would changethe free energy of binding of the complex by –5.6 kcal/mol(unrestrained free energy simulations), by –0.5 kcal/mol(free energy simulations with a restrained backbone) and by1.8 kcal/ mol (Poisson-Boltzmann calculations, which also usea restrained geometry model). A detailed structural analysishelps in estimating the contributions from various residuesand regions of the system. Enhanced recognition of HEL by themutant HyHEL-10 would arise from the combination of thermodynamicallymore favorable conformational changes of the CDR loops uponassociation and subsequent charge pairing with Lys96 in theantigen.

Evaluation of Textile Bobbins Drying Processes: Experimental and Modelling Studies

Drying of textile bobbins was carried out on two kinds of laboratory-scale dryers: in a cross circulation drying rig, atmospheric pressure heating air is used, while in the through circulation drying apparatus, the heating air is pressurized before the drying process takes place. In both cases, a bobbin was fitted with seven thermocouples, placed in a plane normal to the bobbin axis but at different radial distances, in order to provide temperature data during the drying process. In cross circulation drying, plots of temperature against time indicated the presence of two moving fronts, one starting from inside the bobbin, another from the outside, while in through circulation drying, similar plots showed the presence of an evaporation front, moving from inside the bobbin to the outside. In both canes, numerical models were developed to simulate the drying processes.
