Slope failure is a common phenomenon all over the world on both man-made and natural slopes. Prolonged rainfall is one of the climatic factors which is largely responsible for slope failure. During heavy and prolonged rainfall, a part of the rainwater infiltrates through the soil and seeps into the slope. The infiltrated water lowers the matric suction and increases the porewater pressure. Eventually, the generated porewater pressure decreases the strength of the soil which results in slope failures. To evaluate the effect of rainwater seepage on slope stability, it is necessary to investigate the hydraulic conductivity of the slope soil. The objective of this study is to evaluate the effect of hydraulic conductivity on slope failure mechanisms. A finite element analysis of slope stability was conducted using Geo-Studio software. A numerical model was developed and calibrated with field monitoring data. The field monitoring data included the observation of hydraulic conductivity using a Guelph Permeameter. Afterward, the temporal variation of rainfall and hydraulic conductivity was incorporated into the SEEP/W program and the consequent changes in slope stability were evaluated in SLOPE/W. From the numerical analysis, with the identical strength parameters of the soil, different factors of safety were observed when the slope sections retain different hydraulic properties. Based on the numerical analysis, it was observed that hydraulic conductivity greater than 4×10-6 cm/s leads to slope failure. Periodic monitoring of hydraulic conductivity in the field may provide deep insight into rainfall-induced slope failures.

An increasing large number of cornfield have been cultivated in highland of many Southeast Asian countries. In most cases, this corn plantation is done without proper soil & water conservation such as vetiver system (VS), thus causing land degradation and shallow slide. This study is aimed at investigating the field behaviour of slopes with corn plantation with and without vetiver system in Chiang Mai, Northern Thailand. Tensiometers, soil moisture sensors, in-place inclinometers and tiltmeters were installed at a slope in two locations, with and without vetiver system from surface to 2m depth. The monitoring results show that for the vetiver treatment, the soil moisture tended to be higher and response faster to rainfall than the cornfield without vetiver. However, the pore-water pressure in the root zone (about 0.5m) was higher for the vetiver treatment than the cornfield which only has the root depth of about 0.2m. For cornfield without vetiver, the seasonal variation of the soil moisture and pore-water pressure was also larger. Tiltmeter indicates a larger surface movement in the cornfield without VS. However, the inclinometer readings suggested that for slope with VS there was some cyclic movement toward hillside at the surface. This could be an indication of non-uniform settlement of soil layers or influence of groundwater rising.

An experimental study regarding the hydro-mechanical behaviour of a Malaysian Kaolin is presented. Strain rate-controlled oedometer tests have been conducted on compacted samples. The influence of initial water content on the pore-size distribution (PSD) of compacted samples was investigated by Mercury Intrusion Porosimetry (MIP) tests. The drying path of the soil-water characteristic curve was experimentally determined for initially compacted samples and slurry samples. The preconsolidation stress was found to increase with increase in initial dry density and with decrease in initial water content. The compression curves merge into a single line, as soon as they have reached full saturation during loading. Samples at the dry side of Proctor water content showed a bi-modal PSD, whereas a mono-modal PSD was found for Proctor water content and at the wet side. The different initial compaction states of the samples were getting reflected in the drying SWCC until a suction of about 2 MPa, beyond which the drying paths were found to be identical.

A safe transportation ecosystem encompasses both the passenger and attendant populations as well as the abiotic infrastructure that surrounds them. Solar cells generating electricity are one of the most promising options for building a long-term energy base for the transportation ecosystem, given the trends related to the increasing role of green energy in various industries. The physical foundations for the practical implementation of solar cells are being laid by research in nanophotonics. The role of model representations based on FRET and reverse transport mechanisms are examined in the example of luminescence photodynamics of a heterostructure representing isolated films of CdSe/ZnS-TOPO quantum dots containing InP/InAsP/InP nanowires. The studies performed in this work suggest practical ways to increase the luminescence yield of heterostructures using “interfacial technologies” in core-shell structures.

This article discusses the construction of a mathematical model of accelerated chemical-technological processes. Usually, in practice, the problem of building models of multi-stage processes, as a rule, is complicated by the universality, uncertainty and nonlinearity of the objects being modeled, the complete or partial lack of expert experience and an analytical description of dependencies. Mathematical models describing chemical technologies are considered to break down the state into discrete stages. The study below allows us to recommend stage processes to be considered as continuous functions.

The paper presents the results of the mathematical modelling of external stimuli to improve the efficiency of the removal of grain material from the grinding zone. Thus, the authors proposed to improve the evacuation conditions of the finished product from the working chamber of the crushing plant, as one of these solutions to improve the grinding process in crushers. As a result of creation of external vibrating influence. For this purpose, the calculation chart for modelling the proceeding process of the crushing plant body movement is created which takes into account weight and sizes of the crusher, weight, angular velocity of rotation and eccentric piece location, as well as rigidity of an elastic suspension on which the crusher is established. For the solution of the posed problem, we used methods of analytical mechanics, the Lagrange equation of the second kind, for the mechanical system with two degrees of freedom. As a result of calculations amplitude-frequency characteristics of mechanical system are determined. The conclusion about the choice of the angular velocity of the eccentric rotation for creation of necessary external stimulating influence on the crushing system and improvement of conditions of evacuation of a ready product from a working zone is given. The resonance frequencies of firstand second-order system vibrations and the vibrator frequency are determined to achieve resonance frequencies. Keywords: vibration, modelling, Lagrangian equations of the second kind, grinding, crushing plant.

During the drying process, the more time the paddy pile is in the dryer, the higher the drying efficiency of the device. Thus, the movement of the paddy along the OX axis is one of the main factors affecting the drying efficiency of the device. Paddy movement along the OX axis depends on the speed of the drying agent. Therefore, in experimental studies, it is advisable to determine the optimal value of the speed of the drying agent in the range from 0,25 m/s to 0,75 m/s. The number of revolutions of the dryer drum provides mixing of the paddy mound. The mixing of the paddy during the drying process is one of the factors that leads to an increase in the drying efficiency of the device. Therefore, it is advisable to determine the optimal value of the number of revolutions of the dryer drum from 16 min-1 to 22 min-1.
在干燥过程中，稻谷堆在干燥机中的时间越长，设备的干燥效率越高。因此，稻谷沿OX轴的运动是影响设备干燥效率的主要因素之一。稻谷沿OX轴运动取决于干燥剂的速度。因此，在实验研究中，宜在0.25 m/s ~ 0.75 m/s范围内确定干燥剂速度的最佳值。干燥滚筒的转数提供了稻谷的混合。干燥过程中稻谷的混合是导致设备干燥效率提高的因素之一。因此，烘干机滚筒转数以16 min-1 ~ 22 min-1为最优值为宜。
