Effect of Terrestrial LiDAR Point Sampling Density in Ephemeral Gully Characterization

Open Journal of modern Hydrology 2013年第1期3卷 38-49页

Gully erosion can account for significant volumes of sediment exiting agricultural landscapes, but is difficult to monitor and quantify its evolution with traditional surveying technology. Scientific investigations of gullies depend on accurate and detailed topographic information to understand and evaluate the complex interactions between field topography and gully evolution. Detailed terrain representations can be produced by new technologies such as terrestrial LiDAR systems. These systems are capable of collecting information with a wide range of ground point sampling densities as a result of operator controlled factors. Increasing point density results in richer datasets at a cost of increased time needed to complete field surveys. In large research watersheds, with hundreds of sites being monitored, data collection can become costly and time consuming. In this study, the effect of point sampling density on the capability to collect topographic information was investigated at individual gully scale. This was performed through the utilization of semi-variograms to produce overall guiding principles for multi-temporal gully surveys based on various levels of laser sampling points and relief variation (low, moderate, and high). Results indicated the existence of a point sampling density threshold that produces little or no additional topographic information when exceeded. A reduced dataset was created using the density thresholds and compared to the original dataset with no major discrepancy. Although variations in relief and soil roughness can lead to different point sampling density requirements, the outcome of this study serves as practical guidance for future field surveys of gully evolution and erosion.

Intense Visible Photoluminescence from C46H22N8O4Km (m = Co, Fe, Pb) Derivatives Thin Films

引用

Advances in materials Physics and Chemistry 2011年第3期1卷 57-63页

作者： maría Elena Sánchez Juan Carlos Alonso jerry Nathan Reider 不详

Strong visible photoluminescence (PL) at room temperature is obtained from thermal-evaporated thin solid films of metallophthalocyanine (m = Co, Fe, Pb) and double potassium salt from 1,8 dihydroxyan-thraquinone. The PL of all the investigated samples is observed with the naked eye in a bright background. The deconvolution of the normalized PL spectra shows that each PL spectrum is composed of four emission bands which peak at approximately the same energies of 2.1, 2.2 and 2.4 eV and whose intensities and widths depend upon the structure of the complexes. FTIR and ellipsometry are employed to investigate the structural differences among the films. The optical absorption of the films is also investigated to evaluate the changes in the electronic structure of these metal organic compounds, with respect to other metalphtalocya-nines thin films. Our results suggest that the visible PL comes from radiative transitions between energy lev-els associated to the double potassium salt coordination to the metallic ion in the phthalocyanine.

Effect of Irrigation method and Non-Uniformity of Irrigation on Potato Performance and Quality

引用

Journal of Water Resource and Protection 2016年第3期8卷 277-292页

Potato growth, yield, and quality under improved irrigation methods and non-uniformity of their irrigation applications are important to enhance water management in arid regions. A field experiment was conducted in 2014 spring and fall growing seasons using potato (Solanum tuberosum) grown in northern Egypt at Shibin El Kom, menofia, Egypt to evaluate potato response to furrow or trickle irrigation. A Randomized Split-Plot Design with irrigation method randomly distributed and non-uniformity of irrigation applications evaluated along either irrigation furrow or trickle lateral as dependent variables measured at the 3rd, 13th, 23rd, 33rd, 43rd and 53rd m along the 55 m irrigation line. Traditional (TF) and partial (PF) furrows as well as trickle point (TP) and line (TL) sources were used as irrigation methods. Each treatment was repeated three times. For a 33rd m treatment, seasonal optimum water use by potato was 328, 234, 269 and 292 mm over 118 days in spring and 200, 164, 178 and 186 mm over 122 days in fall under TF, PF, TP and TL irrigation methods, respectively. Potato tuber yield and quality were significantly affected by growing season (S), irrigation method (I) and non-uniformity of irrigation application (U). Tuber yield, total soluble solid (TSS) and leaf area index (LAI) were significantly affected by I and U, and their interaction I * U;harvest index (HI) was not affected by I but U. Except for TSS by S * I and HI by U * I and S * I, results showed no significant differences. moreover, tuber weight, number and marketable yield were significantly affected by S, I, U and I * U interaction, except medium tuber size and culls by S. A given 33rd treatment under partial furrow and trickle irrigation, relative to that of traditional furrow, enhanced tuber yield and improved quality in both growing seasons. In non-un- iform irrigation application over two growing seasons, po

本文用声学波动方程的简正波解法实现了层状背景和点震源情况下的傅氏反向传播反演。该法将描述均匀性的目标函数谱分解成来自各层的谱,然后将选择规则用于各个层位谱上。而且,由于分层简化为单层,该法采用的传播阵滤波器简化为单位阵,它不同于均匀基岩介质反演法。该理论直接涉及的是圆柱形背景介质中的点震源,所以在用于野外资料时,它不需要象以前的绕射层析成像算法一样做2.5维校正。

在大冶市典型重金属污染地区,选择罗家桥街办作为污染区、茗山乡作为对照区,通过采集土壤和蔬菜样品,分析5种重金属(Cu、Zn、As、Cd、Pb)的含量,评价重金属对当地居民的健康风险,评价参数根据当地居民调查得到。结果表明,污染区土壤样品的5种重金属的平均值均高于背景值,对照区土壤样品的5种重金属的平均值与背景值差异不显著或低于背景值。污染区蔬菜样品的5种重金属的平均值也基本都高于对照区。因此,污染区土壤已经受到了重金属的污染,对照区土壤几乎未受到重金属的污染。健康风险评价结果表明,污染区人群面临着非致癌风险和致癌风险,而对照区健康风险较小。从年龄层看,对非致癌风险抵抗力最弱的是儿童,而对致癌风险抵抗力最弱的是成人。污染区最主要的风险元素是Cd和As。
