Gd_(2) O_(3) nanoparticles modified g-C_(3) n_(4) photocatalytic composites were synthesized by a simple one-step hydrothermal *** structure,morphology,optical properties of the prepared photocatalyst were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FESEM),field emission transmission electron microscopy(FETEM) and X-ray photoelectron spectroscopy(XPS).The result demonstrates that gadolinium is mainly dispersed on the surface of g-C_(3) n_(4) in the form of Gd_(2) O_(3),and does not destroy the lattice structure of g-C_(3) n_(4).Besides,the gadolinium can cause the red shift of the absorption edge of light,narrow the band gap,and increase the separation efficiency of the photogenerated electron and hole of g-C_(3) n_(4).Especially,the specific surface area of g-C_(3) n_(4) can be significantly ***,g-C_(3) n_(4)/Gd-0.05 displays the highest photodegradation performance when it is used for degradation of methyl orange(MO),methylene blue(MB) and Rhodamine B(RhB).The photodegradation rate of g-C_(3) n_(4)/Gd-0.05 composites is 72.4% for MO,95.5% for RhB,100% for MB after120 min under visible light(λ> 420 nm) *** band gap promotes the separation of photogenerated electron and hole,which enhances the photocatalytic activity of g-C_(3) n_(4).It is noted that g-C_(3) n_(4)/Gd-0.05 exhibits excellent photocatalytic stability by the photocurrent and the cyclic photodegradation of MO.

Capacitance Sensor for nondestructive Determination of Total Oil Content in Peanut Kernels

引用

Journal of Sensor Technology 2013年第3期3卷 42-46页

作者： Chari V. Kandala rao C. n. Rachaputi Daniel O’Connor Agricultural Research Service United States Department of Agriculture Dawson USA Center for Plant Science University of Queensland Kingaroy Australia

In this work, attempts were made to estimate the total oil content (TOC) in single peanut kernels, using the CI meter (Chari’s Impedance meter, described below). Mature peanut kernels of selected varieties with a range of oil contents from 47% to 61% were placed one at a time, between the parallel-plate electrodes of the CI meter, and the impedance (Z) and phase angle (q) of the system were measured, and capacitance, C was computed at 1, 5 and 9 MHz. After the measurements, the TOC of each kernel was determined by Soxhlet method. Using the known TOC values, and the corresponding C, Z and q values, initially on a calibration group of kernels, calibration equations were developed. Using the model coefficients from the calibration, the TOCs of kernel samples of 31 diverse peanut genotypes grown in different environments in Australia were determined. The method predicted the TOC values of peanut kernels of 31 peanut genotypes, within 2% of the Soxhlet values, with an R2 of 0.87 (P 0.001).

室内岩心驱替实验已确定了了解油藏中流体流动性质的主要步骤。油水相对渗透率或许是岩心驱替实验得到的最普遍的参数，但这些参数只能求助于数学模型中岩石-流体所有相互作用的研究结果才能描述油藏流动现象。岩石的润湿性是对油藏流体流动机理有强烈影响的因素之一，因此，在过去几十年，有大量根据岩心驱替实验推测润湿性的论文。另一方面，传统上认为原油-水-固体体系中观察到的接触角是真实的或通用的度量润湿性的参数。因此，出现了一个明显的问题：根据岩心驱替推测的润湿性与接触角之间有联系吗？根据以前的文献似乎不能得出确定性的回答，原因有二个方面：①Craig广义经验方法虽然可以近似比较，尤其是极端情况下润湿的比较，但不能直接推导出表征润湿性的岩石——流体相互作用的大小；②常规的接触角测量普遍存在一个再现性问题。在其它文献中报导的双滴双晶板（DDDC）技术，似乎解决了接触角测量中再现性这个长期存在的问题。本文的目的是将对差别较大的岩石-流体体系用有再现性的DDDC法检测结果与用油藏和贝雷岩心进行的水驱实验得到的对应油水相对渗透率相比较。共比较了10种不同实验结果。其中有8种岩石-流体体系水驱实验结果与接触角测量结果得出的润湿性类似，而其余两种差别明显。对结果的一致性与差异性进行了解释，重点是弄清岩心分析与油藏流体分布和流动机理之间的重要关系。

我国北方地区黄土塬覆盖区的静校正问题是地震数据处理中的难点问题之一.黄土塬表层覆盖巨厚黄土,高差起伏较大,地震静校正问题严重;而且黄土塬覆盖区的潜水面普遍较深,常规折射静校正方法无法取得令人满意的处理效果.本文针对黄土塬覆盖区的静校正难题,研究层析反演静校正方法在黄土塬地区的适用性和可靠性.层析反演静校正利用地震波初至走时数据、通过迭代反演的方法构建速度模型,进而依据所得的近地表速度模型对地震数据进行静校正处理.本文的迭代反演采用同步迭代重构算法(SIRT),并且对同步迭代重构算法进行了改进,使得层析反演的迭代过程趋于稳定.但是,因为黄土塬覆盖区地表高程的横向变化剧烈,相邻检波点的高差及其静校正量有时差异很大,在运用层析静校正求取长波长静校正量的同时,还需采用初至波剩余静校正方法求取短波长静校正量.实例证明,综合应用依据初至波走时数据的层析静校正和剩余静校正方法,同时计算长波长和短波长的静校正量,能够有效地解决黄土塬覆盖区实际地震资料的静校正问题.

Effect of mixed-cropping and water-stress on macro-nutrients and biochemical constituents of rhizomatous medicinal plants in Central Himalaya,India

引用

Journal of Forestry Research 2012年第4期23卷 615-621页

作者： L.S.Kandari K.S.rao R.K.Maikhuri Kusum Payal School of natural Resources Management and Environmental Sciences College of Agriculture and Environmental SciencesHaramaya UniversityP.#Box 337Dire DawaEthiopia Department of Botany University of DelhiDelhi-110007India G.B.Pant Institute of Himalayan Environment&Development Srinagar246174UttarakhandIndia.

Plants in the alpine zone mainly depend on the reserved food materials stored in their rhizomes for the next growing season. We investigated the effect of mixed cropping （Phaseolus vulgaris L. var. Pinto） with four rhizomatous medicinal plants, i.e., Angelica glauca, Arnebia benthamii, Rheum emodi and Pleurospermum angelicoides as well as three levels of water stress treatment under two conditions （shade net and open field） on macronutrients （nPK） and biochemicals （carbohydrates and protein）. The experiment was conducted by completely randomized design （CDR）. The data were analyzed with AnOVA as well as CDR. The experimental results show that in all the species shade conditions with sever water stress （SSWS） increased the level of macronutrients （nPK）. However, （n） concentration was highest under shade with mixed cropping （SMIX）. Under SMIX, carbohydrate content was highest than open field control conditions （COnT）. This investigation results demon- strate that mixed cropping of medicinal plants with Phaseolus vulgaris could be a good livelihood option in the mountainous regions of Indian Central Himalaya. And the water-stress conditions along with mixed cropping could improve the biochemical constituents in the rhizome of these species.
