HoPLLS (Hierarchy of protein loop-lock structures) (http://***/~skogan/Apache/mydata1/***) is a web server that identifies closed loops-a structural basis for protein domain hierarchy. The server is based on the loop-and-lock theory for structural organisation of natural proteins. We describe this web server, the algorithms for the decomposition of a 3D protein into loops and the results of scientific investigations into a structural “alphabet” of loops and locks.

Uranium-europium mixed oxides(U_(1-y)Euy)O_(2-x)(y=0.2-0.8)were prepared by the citrate gel combustion technique and characterized by X-ray diffraction(XRD).Single phase fluorite structure was observed in those solid solutions with y≤*** solid solutions with y>0.6 were found to be biphasic,with the second phase being cubic *** capacity and enthalpy increment measurements were carried out by using differential scanning calorimeter(DSC)and drop calorimeter in the temperature range 298-800 K and 800-1800 K,***,pm C values at 298 K for(U_(1-y)Euy)O_(2-x)(y=0.2,0.4,0.6)are 64.8,64.6,and 63.5 J·K^(-1)·mol^(-1),*** anomalous increase was observed in the heat capacity in all of the solid solutions with the onset temperature around 950 *** could be attributed to the contribution from frenkel pair oxygen *** the excess heat capacity data,the enthalpy for the formation of these defects was computed and found to be in the range of 2.10±0.02 eV.

Arsenic, a common environmental and occupational contaminant, is classified as a human carcinogen. The mechanism by which arsenic causes cancers in humans, however, is not completely elucidated yet. It is well known that chronic inflammation results in oOxidative stress and oxidative cell damage, which have been demonstrated to be involved in the process

Journal of Semiconductors 2017年第11期38卷 39-47页

作者： g.Nagaraju K.Ravindranatha Reddy V.Rajagopal Reddy Department of Physics Sri Venkateswara University Tirupati-517 502 India Department of Physics SGS Arts College Tirupati-517 502 India

The electrical and current transport properties of rapidly annealed Dy/p-gaN SBD are probed by I-V and C-V techniques. The estimated barrier heights（BH） of as-deposited and 200 ℃ annealed SBDs are 0.80 eV（I-V）/0.93 eV（C-V） and 0.87 eV（I-V）/1.03 eV（C-V）. However, the BH rises to 0.99 eV（I-V）/1.18 eV（C-V）and then slightly deceases to 0.92 eV（I-V）/1.03 eV（C-V） after annealing at 300 ℃ and 400 ℃. The utmost BH is attained after annealing at 300 ℃ and thus the optimum annealing for SBD is 300 ℃. By applying Cheung＇s functions, the series resistance of the SBD is estimated. The BHs estimated by I-V, Cheung＇s and ΨS-V plot are closely matched; hence the techniques used here are consistency and validity. The interface state density of the as-deposited and annealed contacts are calculated and we found that the NSS decreases up to 300 ℃ annealing and then slightly increases after annealing at 400 ℃. Analysis indicates that ohmic and space charge limited conduction mechanisms are found at low and higher voltages in forward-bias irrespective of annealing temperatures. Our experimental results demonstrate that the Poole-frenkel emission is leading under the reverse bias of Dy/p-gaN SBD at all annealing temperatures.

着眼于人力资源管理的理论研究与管理实践不完全契合,认为人力资源管理应是一个整体,且人力资源管理信息有效传递和被员工有效感知是人力资源管理的关键。以两家劳动密集型企业364名员工为样本,探讨了人力资源管理强度对员工工作态度的影响。结构方程模型分析结果表明:人力资源管理强度对工作满意度和组织认同感有显著正向影响;主管支持感在人力资源管理强度和员工工作态度之间起到部分中介作用。最后,针对研究结果进行了讨论。

铜基催化剂的价态组成与制备方法、还原温度有关,也是决定其催化性能的关键因素.本文对比研究Cu-Zn/SiO_2和Cu/SiO_2催化剂前驱体在不同还原温度下的价态组成及其醋酸甲酯加氢性能.采用同步辐射X射线吸收谱原位表征催化剂前驱体的Cu K边的X射线近边吸收谱(XANES),通过线性组合分析方法(LCF)拟合XANES吸收谱得到了催化剂前驱体在不同还原温度下氧化态(Cu^(2+)、Cu^+)和金属态(Cu0)的组分含量.结果表明:(1)采用蒸氨法添加Zn制备的Cu-Zn/SiO_2催化剂前驱体铜组分还原度高;(2)催化剂前驱体在还原过程中Cu^+主要存在于低温还原阶段(<250℃),且Cu^0+Cu^+含量较低(≤40%);(3)金属态铜是醋酸酯加氢反应的活性中心.
