Abstract The Borneo Accretionary Orogen (BAO) is located in a central position of SE Asia, surrounded by the long‐lived westward subduction Pacific Plate, northward Indian Plate beneath Eurasian and passive continental margin South China Sea. Based on previous studies stratigraphy, structural geology geophysics, number tectonic models BAO have been proposed, but these do not perfectly match all geological facts. A field‐based analysis rocks Sabah Malaysia has recognized that deformation can...

GaAs metal-oxide-semiconductor field-effect transistors (MOSFETs) using wet thermally oxidized InAlP as the gate insulator are reported for first time. Leakage current measurements show that 11-nm-thick native oxide grown from an In/sub 0.49/Al/sub 0.51/P layer lattice-matched to has good insulating properties, with a measured leakage density of 1.39×10/sup -7/ mA/μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> at 1 V bias.

Under rapid global climate change, the risk of ancient landslide reactivation induced by rainfall infiltration is increasing significantly. The contribution cracks to landslides, as an evolutionary product, a topic that deserves attention; however, current research on this issue remains insufficient. In study, taking Woda in upper Jinsha River case we investigated mechanisms landslides with and without under based model tests. study showed influence range depth landslide. cases where no...

In this article, we introduce a method for monitoring the Weibull shape parameter β with type II (failure) censored data. The control limits depend on sample size, number of observations, target average run length, and stable value β. assumes that scale α is constant during each sampling period, which true under rational subgrouping. proposed utilizes relationship between smallest extreme distribution. We propose an unbiased estimator σ = 1/β as statistic. derive one-sided two-sided charts...

Reservoir landslide is a type of commonly seen geological hazards in reservoir area and could potentially cause significant risk to the routine operation hydropower station. It has been accepted that landslides are mainly induced by periodic variations water level during impoundment drawdown process. In this study, better understand deformation characters controlling factors landslide, multiparameter-based monitoring program was conducted on landslide—the Hongyanzi located Pubugou southwest...

Carbon emissions from China’s forest products industry were considered based on the data of 2001-2020. Then a carbon Kuznets curve was constructed to judge relationship between economic development level and emissions. The logarithmic mean Divisia index (LMDI) used analyze influencing factors showed trend rapid growth in early stage slow decline later stage, increasing 19.46 million tonnes 2001 54.18 2020. Consumption raw coal main reason for increase There an inverted-U emissions, output...

Abstract Landslide geological hazards are widely distributed and frequently occur in China, especially the western high mountains valleys where terrain is steep vegetation dense also a large number of hidden large-scale landslide hazards. To solve problems early identification landslide, we took mountain valley area Shimian–Hanyuan section Dadu River as research object. conduct an study area, used interferometry synthetic aperture radar (InSAR) technology optical remote sensing technology....

A large‐scale model test on the interaction between a micropile group and landslide was conducted, to investigate effect of micropiles landsides prevention. The bearing mechanism, force condition, failure mode for reinforcing were analyzed in detail. results showed that thrust over induced by trapezoidal distribution, with higher Earth pressure near sliding surface. resistance from body behind pile behaved parabolically trend. Meanwhile, bed distributed unevenly along height direction,...

The objective of this study was to determine the feasibility recycled phosphogypsum (PG) as an embankment material with soil by performing batch and column ecotoxicity experiments. A. salina, D. magna, O. latipes S. capricornutum were selected for experiment. effective concentration (EC₅₀) magna lowest value, 1.29 mg/L. survival rates more than 90% in presence PG leachate test. toxicity unit (TU) organisms less 1, indicating that no significant effect found. These findings...

Time series Autoregressive Integrated Moving Average (ARIMA) model is often used in landslide prediction and forecasting. However, few conditions have been suggested for the application of ARIMA models displacement prediction. This paper summarizes distribution law tangential angle different time periods analyzes data by combining wavelet transform. It proposes an applicable condition field prediction: when deformation initial to acceleration stage, i.e., less than 80°, has higher accuracy...

This paper is focusing on the investigation of a novel anoxicoxic hybrid membrane bioreactor (A/O HMBR) for treatment landfill leach ate. new technique combined an efficient anoxic and oxic biological process with filtration unit has advantages simplifying pre-treatment facilities, relieving loading subsequent processes optimizing whole process. The results showed that after two months sludge acclimation, average removal efficiency COD, ammonia nitrogen total in effluent from A/O achieved...

Landslides are the most serious geological disaster in our country, causing economic losses. Because they go undetected, a large number of landslides that have caused disasters not catalogue. At present, Interferometric Synthetic Aperture Radar (InSAR) has been widely used identification landslides. However, it is time-consuming, inefficient, etc., to survey throughout country. In context massive SAR data, this problem more obvious. Therefore, based on current technique using differential...

The design and analysis of Cable-Supported Bridges (CSBs) with Road Railway Traffic (RRT) are very complex due to the many boundary conditions structural options, e.g. railway tracks road lanes can be arranged on one level, two levels, staggered levels or mixed levels; main girders may truss girders, a single box girder, separated combined truss–box girder. With experience several national international competitions, this paper describes principles conceptual CSBs RRT, mainly focused...

Using a unique survey data of Chinese households, we study the impact house price growth and risk on entrepreneurship. House risk, measured as sensitivity to local GDP growth, negatively impacts entrepreneurship homeowners relative renters. This finding is concentrated only among sophisticated households consistent with portfolio effect when housing occupational choices are integral parts household portfolio. Moreover, high past reduces holds for both unsophisticated households. We propose...

Abstract Water saturation estimation faced a great challenge in tight gas sandstone reservoirs because of the effect pore structure and strong heterogeneity to rock resistivity. The classic Archie’s equation cannot be always well used. To quantify resistivity sandstones, taking Triassic Xujiahe Formation northwestern Sichuan Basin as an example, 35 core samples were recovered applied for experiments laboratory under simulated formation temperature pressure environment, 18 them simultaneously...
