ФОРМУВАННЯ ГІДРОДИНАМІЧНОГО РЕЖИМУ В ЗОНІ ВПЛИВУ ВІДВАЛІВ ГІРСЬКИХ ПОРІД ТА ХВОСТОСХОВИЩ

За результатами моделювання з використанням тривимірної чисельної моделі, що комплексно відбиває планово-профільну фільтрацію в межах прони-кних і розділяючих шарів, встановлені закономірності геофільтрації у верхній частині породного масиву на ділянках розташування відвалів гірських порід і хвостосховищ. Виявлений характер впливу гідродинамічного режиму, що формується в умовах гравітаційно-навантаженого породного масиву, на гео-механічний стан прилеглої до об'єктів гірничого виробництва території. По результатам моделирования с использованием трехмерной численной модели, комплексно отражающей планово-профильную фильтрацию в пределах проницаемых и разделяющих слоев, установлены закономерности геофильтрации в верхней части породного массива на участках расположе-ния отвалов горных пород и хвостохранилищ. Определен характер влияния гидродинамического режима, формирующегося в условиях гравитационно-нагруженного породного массива, на геомеханическое состояние прилегаю-щей к объектам горного производства территории. The features of ground water flow have been determined for the top layers of the rock mass in dump tailing areas by numerical simulation using a model reproduc-ing 3D ground water flow within aquifers and confining layers. The impact of the hydrodynamic regime formed in the gravitationally loaded rock mass on geomechanical conditions of the territory affected by mining industry sites has been revealed

The choice of feedstock for the biodiesel production with optimal physicochemical and low-temperature properties

The transesterification reaction of sunflower, mustard and linseed oil with ethyl alcohol was studied using potassium hydroxide as a catalyst. The physicochemical properties and low-temperature characteristics of the feedstock and obtained products were studied. The most preferred feedstock for the biodiesel fuel production had been determined

Visual shape and position sensing algorithm for a continuum robot

Continuum robots represent an actively developing and fast-growing technology in robotics. To successfully implement control and path planning of continuum robots it is important to develop an accurate three-dimensional shape and position sensing algorithm. In this paper, we propose an algorithm for the three-dimensional reconstruction of the continuum robot shape. The algorithm is performed during several steps. Initially, images from two cameras are processed by applying pre-processing and segmentation techniques. Then, the gradient descent method is applied to compare two-dimensional skeleton points of both masks. Having compared these points, it finds a skeleton of the robot in a threedimensional form. Additionally, the proposed algorithm is able to define key points using the distance from the robot base along the center line. The latter allows controlling the position of points of interest defined by a user. As a result, the developed algorithm achieved a relatively high level of accuracy and speed

Reinterpretation of LHC Results for New Physics: Status and recommendations after Run 2

We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental offerings in direct searches for new particles, measurements, technical implementations and Open Data, and provide a set of recommendations for further improving the presentation of LHC results in order to better enable reinterpretation in the future. We also provide a brief description of existing software reinterpretation frameworks and recent global analyses of new physics that make use of the current data

Flow-Directed Catheters in Hepatic Embolization Therapy—A Review with Clinical Cases

Transarterial embolization with chemotherapy and radiation is well-documented forms of treatment for liver cancers but reflux of embolic particles to nontarget tissues can result in unintended consequences such as gastrointestinal ulceration. Traditionally, operators have used coil embolization of hepatoenteric collaterals to prevent reflux. Antireflux microcatheters that contain expandable baskets (Surefire) or inflatable balloons have recently been developed as tools to avoid these side effects. We describe cases where antireflux catheters were used instead of coil embolization. Using antireflux catheters, we eliminated particle reflux into nontarget vessels. We also review the literature on antireflux catheters involved in preventing reflux during chemo- and radioembolization
