The paper is devoted to the issues of judicial control in modern Russian pre-trial proceedings in criminal cases.
The concept of judicial power is considered, including in the context of the ...development of scientific ideas about its nature. Based on the developed ideas about this concept and the goals of the judiciary, the author substantiates the thesis that judicial control is an independent function of the judiciary.
Next, the features of the parties to disputes resolved through judicial control, their subject are analyzed, and on this basis, the author’s perception of the content of judicial control in pre-trial proceedings in criminal cases is proposed. In conclusion, the issue of the place of judicial control in pre-trial proceedings in criminal cases is considered through the prism of the structure of criminal proceedings. A classification of judicial control proceedings that may exist at the specified stage of the process, depending on their subject, is proposed. The need for further research is stated, due to the insufficiency and inconsistency of regulation of the powers of the court in the exercise of judicial control.

•HDS of SRGO with high content of sulfur and its mixture with CGO were studied.•Four kinetic models of desulfurization with different complexity were compered.•The models are differ ...in insight into the reactivity of sulfur-containing compounds.•Better prediction give models taking into account the difference in sulfur reactivity.
The hydrodesulfurization of straight-run gas oils (SRGO-HS) with high content of sulfur (about 2 wt%) and its mixture with light coker gas oil (CGO) has been studied over CoMo/Al2O3 catalyst using a trickle bed down-flow reactor at the 335–365 °C, H2/HC − 300 Nm3/m3, LHSV − 0.8–2.5 h−1 and 3.5–5.1 MPa. The possibility of ultra-low sulfur diesel (<10 ppmS) production using feedstocks with sulfur content exceeding 2 wt% was demonstrated under conditions simulating industrial one. To predict the effect of process parameters on the amount of sulfur in products four kinetic models with different insight into the reactivity of individual S-containing compounds were considered. The first model is simplified kinetics based on power law rate equations, taking into account overall sulfur content, the second group includes LHHW type rate equations. The models 3 and 4 take into consideration the difference in the reactivity of sulfur-containing components. Model 3 classifies the total sulfur into two subgroups Se (easy reactive compounds) and Sr (refractory sulfur compounds - dibenzothiophene and its derivatives). In Model 4 the group Sr is divided into three more subgroups. Kinetic rate parameters i.e. frequency factors, apparent activation energies, and adsorption enthalpies, were estimated by fitting the experimental data obtained using the SRGO-HS/CGO feedstock to the models. All kinetic models predicted the experimentally determined conversions of sulfur with a relatively good accuracy (±20%). The kinetic models were verified by comparing the simulation results with the experimental data obtained using the other oil fractions (SRGO-LS) with lower content of sulfur (1.05 wt%). A better agreement was observed between the experiments and prediction by models 3 and 4.

The paper offers a market analysis and review related to secondary (recycled) garnet produced by recycling sludge using the waterjet cutting machines. Industrial quality garnet is a limited natural ...resource. The studies have shown that it is cost-effective to use recycling systems to process the post-waterjet cutting abrasive. A return on investment term was found to be 12 to 14 months, while the profit growth was 20–38%. It is forecasted that up to 15–40% growth in the fraction of recycled garnet used in the waterjet cutting process can be achieved. Arguably, after the abrasive recovery system is implemented, the abrasive-related costs are reduced by 60%. The garnet concentrate sludge can be recycled up to five times. Multiple service companies that offer recycling and recovery of the post-waterjet cutting sludge are being formed globally. Modern installations are capable of sustaining the production volume of up to 12,000 ton/year. A pilot model of the technological process for regenerating post-waterjet cutting garnet concentrate sludge using an electric mass classification technique has been developed. Pilot batches of abrasives for industrial use in waterjet cutting operations and for abrasive-jet machining have been produced. Industrial tests of the obtained 80 and 120 mesh sand samples and their mixture were carried out at the production facilities of the waterjet cutting users.

. It was shown that addition of gas oil to the straight-run gas oil in hydrotreating under the conditions corresponding to the working conditions of the existing domestic hydrotreating installations L-24-5, L-24-6, L(Ch)-24-7 has oppositely directed effects, depending on temperature and feedstock delivery rate. For example, the additives lead in the temperature range 335–350°C to an increase in the content of sulfur in hydrotreating products. At a temperature of 365°C, better sulfur-related parameters are reached in processing of feedstocks containing light coker gas oil. The observed dependences are accounted for as follows: the dilution of the straight-run gas oil by addition of light coker gas oil leads to a decrease in the content of difficulty converted sulfur-containing compounds, but makes larger the content of nitrogen-containing compounds inhibitors of the hydrodesulfurization reaction, the influence of which on the reaction rate becomes weaker with increasing temperature.

The measurement of the direction of WIMP-induced nuclear recoils is a compelling but technologically challenging strategy to provide an unambiguous signature of the detection of Galactic dark matter. ...Most directional detectors aim to reconstruct the dark-matter-induced nuclear recoil tracks, either in gas or solid targets. The main challenge with directional detection is the need for high spatial resolution over large volumes, which puts strong requirements on the readout technologies. In this paper we review the various detector readout technologies used by directional detectors. In particular, we summarize the challenges, advantages and drawbacks of each approach, and discuss future prospects for these technologies.

In the operation of modern gas and steam turbines, the amount of deposits on the aggregate surfaces inevitably increases (mainly in the form of amorphous silicon), which leads to metal corrosion and ...erosion damage. The relevance of solving the problem of removing technological pollution in the process of repairing gas and steam turbines in order to restore the design capacity of the equipment is shown in this paper. The efficiency of using hydroabrasive treatment for performing repair operations on turbine components (rotors, blades, etc.) has been established. The method developed is an alternative to the chemical cleaning processes and mechanical surface abrasion. The technology does not have a negative effect on the environment and has an isolated system of using technological components. The technology (composition of the technological medium) and equipment (high speed and density of particles) provide cleaning of deposits from the gas and steam turbine components, in particular, turbine blades, with a high quality of the resulting surface and the required productivity.

Efficient planning of the improvement of soil hydrophysical properties in reclamation requires a prior assessment of soil quality to determine weak points and the vector of complex impacts on soil. ...The water retention curve and the function of moisture conductivity have a decisive impact on moisture movement in the soil. However, neither WRC nor the function of hydraulic conductivity alone gives a full picture showing moisture supply of plants. Therefore, the function, which is their product, is of particular interest for reclamation purposes. The analytical study of this function allows determining the moisture values related to the transitions from one state to another (the plant wilting moisture, the moisture of the "ripeness" of the soil, etc.) on the bases of laws of Physics. Such types of land clearance operations as sanding, claying as well as breaking up and puddling of soil can be assessed quantitatively applying the above function. The analytical foundation of the fact that less puddled soil reaches a certain level of water holding at higher moisture than more puddled soil has been given. Puddled soil either does not reach such a level or reaches it at lower moisture. The considered function allows estimating the results of increasing the specific surface of soils due to the application of ameliorants. The results of tripolite application in black soil and gray forest soil were received.
