This article describes the designing the third axis on a standard Niva pickup truck. To do this it was necessary to make a traction calculation of the transmission and a dynamic calculation of the suspension. / В данной статье описано проектирование третьей оси на стандартный Нива Пикап. Для этого потребовалось произвести тяговый расчет трансмиссии...
Effects of soil surface degradation and vehicle momentum on dust emissions and visibility reduction from unpaved roads
Unpaved roads are built on the basis of soil compaction. Therefore, the operation of vehicles on these roads results in dust emissions. As the number of passing vehicles increases, the soil surface gradually degrades under shearing caused by the tires. This enhances emissions and reduces visibility, increasing health and environmental related issue...
DEM-VOF simulations on the drawdown mechanisms of floating particles at free surface in turbulent stirred tanks
The drawdown of floating particles in turbulent stirred tanks is widely encountered in industrial processes. However, the data oriented drawdown mechanisms and the dependence of particle dispersion on particle properties and stirred tank structures are lacking. Especially in the simulation works, the effect of the free liquid surface on the drawdow...

Development and validation of a sampling and analysis method to determine biogenic sulfur in a desulfurization bioreacto...
Published in Journal of hazardous materials
Suspended biomass bioreactors can be operated to remove H2S from biogas under anoxic conditions and produce elemental sulfur, the commercial value of which has been demonstrated. In the present paper, a novel methodology comprising the optimization of a determination method performed in a gas chromatograph equipped with a pulsed flame photometric d...
Metal particle seeding on urban surface samples
In order to estimate the resuspension of the particles empirically, it is necessary to carry out a homogeneous distribution of the particles on the tested surfaces. Thus, in many studies, seeding or deposition in experimental chambers is performed to quantify initial concentrations for subsequent resuspension experiments. The current study was carr...
A signal analysis and identification scheme for an online multiphase micron-sized particle analyzer system
Online microparticle detection is of utmost importance for industrial production. This paper proposes a signal processing and feature identification strategy to achieve particle size statistics for online measurement in a three-phase stirred tank reactor based on the electrical sensing zone (ESZ) method. Signal denoising and de-interference are ach...
Results of treatment of trapeziometacarpal osteoarthritis with trapeziectomy and tendon allograft interposition
The aim of the study was to evaluate the results of treatment of osteoarthritis of the carpometacarpal joint of the thumb with tendon allograft interposition. Fifty-three patients (61 hands), 13 men and 40 women, were operated on at a mean age of 61 years. A partial trapeziectomy with tendon interposition was performed in 19 hands and with suspensi...
Numerical simulation of micro-mixing in gas-liquid and solid-liquid stirred tanks with the coupled CFD-E-model
The coupled CFD-E-model for multiphase micro-mixing was developed, and used to predict the micro-mixing effects on the parallel competing chemical reactions in semi-batch gas-liquid and solid-liquid stirred tanks. Based on the multiphase macro-flow field, the key parameters of the micro-mixing E-model were obtained with solving the Reynolds-average...
