Summary Phytophthora species were surveyed by collecting soil samples and placing bait leaves in selected streams during June–October the years 2005, 2006 2010 at three sites oak forests D iqing T ibetan Autonomous Prefecture of NW Yunnan province, China. Seventy‐three isolates P hytophthora spp. recovered from 135 baited leaf 81 samples. Eight identified observation morphological features ITS1‐5.8S‐ITS2 rDNA sequence analysis. The eight taxa included two well‐known P. gonapodyides cryptogea...
Mapping the crustal structure beneath South Yellow Sea (SYS), which includes collision zone between North China Block and Block, will help to reveal geologic history relationship these blocks. Previous interpretations of SYS did not use detailed seismic velocity as a constraint. We produced an upper model northern using new wide‐angle dataset. Velocity anomalies resolved by our models correlate well with known features such sedimentary basins tectonic uplifts in low‐ high‐velocity anomalies,...
Azimuthal electromagnetic logging while drilling (LWD), which is capable of providing accurate position information approaching bed boundary, has been widely applied in real-time geosteering. For the inversion speed and precision azimuthal LWD data, key lies selection proper model corresponding optimization algorithm. In this study, we first simplified complex three-dimensional (3D) data into a series one-dimensional (1D) problems by using dimensionality reduction scheme. Then, feasibility...
Abstract Obolodiplosis robiniae is native to North America and an important introduced insect pest that forms leaf margin roll galls on species of genus Robinia (Fabaceae) in China. It was first detected China 2004, but subsequently spread provoked local outbreaks. An analysis a 676-bp sequence the mitochondrial DNA cytochrome oxidase subunit I conducted 560 individuals from 28 populations, order (1) assess population genetic structuring (2) explore possible explanations for rapid invasion...
The use of ocean bottom seismometer (OBS) is great significance to explore the tectonic evolution East China Sea. To study characteristics deep geological structure from Sea shelf basin Ryukyu trench uplifting fold belt, NW-SE active source seismic experiment (OBS-2015) was carried out in By using delayed fire multilayer gun array, wide-angle reflection and refraction signals up Moho can be obtained continental Okinawa Trough, various phases such as Ps, Pg PmP recognized. data acquisition...
With the research on gender issues for a long time, women's studies have become very mature in all aspects. Although theory is rich, there still little concrete practical progress. This article focuses analysis of perspective female writers and looks at current situation life from their perspective. By perusing considerable number literary works, this paper selects four conducts an representative works to elucidate three types survival predicaments: absence desires, voice, presence...
Abstract. Safe landing is an important part of the planetary exploration mission. Even fine scale terrain hazards (such as rocks, small craters, steep slopes, which would not be accurately detected from orbital reconnaissance) could also pose a serious risk on lander or rover and scientific instruments on-board it. In this paper, simple geometric approach hazard detection safe site selection proposed. order to achieve full implementation algorithm, two easy-to-compute metrics are presented...
Abstract The Sulu orogenic belt, formed by the collision between Sino‐Korean and South China blocks, has important geological implications due to its unique tectonic setting. To understand deep crustal structure of extension belt in Yellow Sea, we presented a 220‐km long active‐source ocean‐bottom seismometer wide‐angle reflection/refraction profile across Sea. obtained P‐wave velocity exhibits significant horizontal vertical variations. middle upper regions north beneath survey line exhibit...
<p>South Yellow Sea was a component of the circum-Pacific continental margin active belt, developing on marine basement during pre-Paleozoic and mid-Paleozoic. The lack detail in offshore seismic model crustal levels means that deep structure remains ambiguous. We processed wide-angle data from 30 sections were acquired 2013 order to achieve continuous 2-D velocity interface using Rayinvr. final velocity/interface along survey lineshows significant horizontal vertical...
Summary The electromagnetic (EM) logging-while-drilling (LWD) measurement plays an important part in high angle and horizontal wells for geosteering formation evaluation. Among types of EM LWD tool, the new generation tools with low frequency large T-R transmitter provides tens meters investigation depths. As a result, structures rock properties far away from borehole contributes to tool responses. Therefore, 3D algorithm is required model problem accurately. In this paper finite difference...
