The viscosities, η, and ultrasonic speeds, u, of pure benzene, triethylamine, （TEA） tributylamine, （TBA）, and those of their binary mixtures, with benzene as common component, covering the whole composition range have been measured at 278.15 k, 283.15 k, 288.15 k, 293.15 k, 298.15 k, 303.15 k, 308.15 k, 313.15 k, and 318.15 k. From the experimental data the deviations in viscosity, △η, deviations in Gibbs free energy, AG, deviations in ultrasonic speed, △u, deviations in entropies, △S^＊, and deviations in enthalpies, △H^＊, of activation of viscous flow have been determined. The sign and magnitude of these parameters were found to be sensitive towards interactions prevailing in the studied systems. Further, the excess molar volumes, VE, were calculated using data for the binary mixtures. Moreover, theoretical values of viscosities and ultrasonic speeds of the binary mixtures were calculated using different empirical relations and theories. The results were in experimental and theoretical values. discussed in terms of average deviations （AD）

In this manuscript, we are reporting structural, bonding, optical, dielectric, and electrical properties of Gd-doped ZnO composite samples (Zn1−xGdxO, x = 0, 0.05, 0.10) prepared by solid-state reaction method. XRD spectra confirm the wurtzite hexagonal phase with a grain size distribution of 42 - 47 nm. The FT-IR spectra confirm bonding behavior like Zn-O, O=C=O, and O-H stretching modes. FESEM micrographs show that the grains of crystallites possess nearly spherical morphology. Optical absorption spectra confirm that the optical band gap decreases systematically from 3.19 eV to 3.15 eV for x = 0.0 to x = 0.10 samples. For all samples, PL spectra exhibited near-band emission, blue emission, and green emission peaks. The dielectric constant decreases as the applied frequency increases. Hall effect results show that with increasing doping concentration of Gd, mobility and resistivity increase while bulk concentration decreases. Current-Voltage study shows that current increases when temperature is increased. Rare earth-doped ZnO is potential material used for optoelectronics and spintronics device applications. Properties of Gd-doped ZnO are studied by various research groups, but dielectric studies are limitedly reported. Therefore, the present research work aims to study the change of electrical, optical, and dielectric properties of Gd-doped ZnO for device applications.

配置空间是算法机器人学领域使用较为广泛的一种基本概念。机器人学、计算机辅助设计与相关领域的诸多应用都可归类为配置空间方面的计算问题。本文将对近期与配置空间相关的两项重大挑战的解决方案成果进行探讨:①如何高效计算高维配置空间的近似表达;②如何在高维配置空间内高效执行几何学接近度与运动规划查询。基于机器学习与几何学近似技术,笔者在此提出几种新型配置空间构建算法。上述算法对多个配置样本进行碰撞查询。得出的碰撞查询结果将用来计算配置空间的近似表达,可快速聚合至准确的配置空间;同时还提出了基于并行图形处理器(GPU)的算法,以便加速配置空间优化与搜索计算的性能情况。笔者特别设计出了基于GPU的并行k最近邻算法与并行碰撞检测算法,并使用这些算法来加快运动规划。

The potential use of biochar as a sustainable soil amendment has recently gained global recognition. The use of biochar as a soil additive is attributed to its ability to improve soil chemical, physical and biological properties. Studies have shown that biochar amendments can enhance soil nutrient retention and availability, pH, water holding capacity, microbial activity and sequester carbon. In this study using corn (Zea mays L.) as an experimental crop, the influence of P availability from modified P enriched Douglas fir biochar (PEB), triple super phosphate fertilizer (SPF), and modified Douglas fir biochar (MB) on plant growth and P Use Efficiency (PUE) were compared. The rate of P applied (0, 30, 60, 90 and 120 kg·ha-1) was calculated based on % P content of each soil additive. Except for MB treatments, P recovery, crop growth and P Use Efficiency increased with application rates. The maximum above ground dry matter yields corresponding to PEB, SPF and MB treatments were estimated at 3488 kg·ha-1, 2449 kg·ha-1 and 639 kg·ha-1, while their respective agronomic P use efficiency (AGE) rates were 32 kg·kg-1, 17 kg·kg-1, 0.5 kg·kg-1. Also, recovery of k, Mg, Ca, Zn, Fe, Cu, B and Mn improved in both PEB (p value 0.9) and SPF (p value 2 > 0.9) treatments. More studies at field scale are needed to demonstrate the practicability of using modified P enriched Douglas fir biochar for soil amendments.

预计2010年碳纤维的市场约为20亿美元,产量约为3.63万t。碳纤维制造工业的主要挑战是成本效率生产。随着成本的降低,其用途将急剧增加。能够直接从PBO纤维制备碳纤维,无需非常费钱耗时的纤维稳定步骤,意味着能够降低成本。PBO纤维的炭化和石墨化产生优质碳纤维,兼有非常好的热和力学性能。与其他原丝生产碳纤维相比,有非常令人感兴趣的远程有序形成。这导致极好的晶格基性能和较低的电阻率。

121Sir,Unburied k-wires left projecting from the fingers after hand surgery can lead to inadvertent injuries if left open,especially in children or disoriented patients,particularly at the time of reversal of anesthesia and in the immediate postoperative *** ways have been described to circumvent *** surgeons twist the k-wire on itself along with capping of the wire tip,but this requires considerable twisting force on an already inserted k-wire,which can lead to malalignment or even refracture.[1]Furthermore,the bent k-wire acts like a hook,catching onto dressing materials or clothes and subsequently may migrate out.
