A promising way of preventive deloading of the vessel's electrical power system
Authors: Saushev Alecsandr , Shirokov Nikolai
Published: January 2023

The method of preventive protection of the ship power system in abnormal situations is considered. Existing devices are shown to form a command to unload electrical power sources after an emergency situation, often resulting in a power outage on the ship. A method of unloading the network, in which the automatic formation of the command to disconnect selected power consumers in the case where at least one of the parallel working genset units is already inoperable, but the quality indicators of generated electricity is still within acceptable limits, is proposed. It is marked, that the offered approach provides forecasting of a power condition of ship electric power system in case of reduction of its generating ability. The conditions under which deloading should be carried out are formulated and presented in the form of logical expressions. It is shown that the proposed approach has a universal character, as it does not depend on the number of generating sets working in parallel, nor on the number of defective machines, nor on the type of incident. The functional scheme of the original device for preventive unloading of the ship electrical power system is presented. It is noted that practical realization of the proposed method of ship electric power network unloading allows in case of at least one of the generating units working in parallel to realize in advance the structural adaptation of system to the arisen failure and to pass in a partially nonfunctional state, bypassing an emergency situation. In this case, there is no interruption in power supply to critical consumers, ensuring the safety of ship operation.

Authors: Karetnikov Vladimir , Burkov Anatoly , Prokhorenkov Andrei , Efimov Konstantin
Published: January 2023

Navigation on inland waterways, such as rivers, canals, fairways via reservoirs and lakes is performed under conditions of a minimum under the keel clearance, hydrodynamic interaction between the ship's hull and underwater limits of the fairway, and the impact of irregular currents. Piloting a ship difficult navigational conditions requires the navigator to monitor continuously the ship’s motion, assess quickly the situation and develop optimal decision for ship handling, have sufficient navigational experience and a large amount of practical knowledge. To achieve a high level of qualification, the training of navigators is carried out in several ways at once - general and particular pilotage, organization of navigation safety and the theoretical foundations of ship handling. Lack of theoretical or practical knowledge can lead to wrong assessment of navigation situation and therefore be considered as factor limiting passage of vessel and navigational safety. The article contains analysis of inland waterways navigation particulars as basis of training for navigators of ships flying foreign flags when entering the inland waterways of the Russian Federation to reduce influence of limiting factors and support the navigational safety.

Authors: Kholoptsev Aleksandr , Podporin Sergey , Ol’khovik Yevgeny
Published: January 2023

The dynamics of the development of the Lena polynya forming in the Laptev Sea and its impact on navigation conditions in the Arctic, in the Laptev Sea, is investigated. The hypothesis is tested that the timing of polynya may have a significant impact on its average growth rate. The results of the GLORYS12v1 global reanalysis and standard methods of mathematical statistics were used in this test. The validity of the hypothesis was confirmed by the example of the section of the polynya located at the mouth of the major navigable channel of the Lena delta Bykovskaya. Stable tendencies of changing the dates of the polynya formation towards earlier dates in the modern period have been revealed. A high probability of improvement of navigation conditions is observed in this region in 2020-2040. However, with further warming of the Siberian climate, the opposite process is possible - the freezing of the polynya that formed too early, which will lead to a colder climate in the region and deterioration of navigation conditions. The selection of general routes for ships in the areas where the polynya is spreading will contribute to more intensive and safer navigation. For this purpose, accurate forecasts of its size and position are required. The relevance of research results for ship traffic forecasting and plans for the use of icebreaker escorts for vessels is noted.

Published: January 2023

Small-sized mobile unit for static testing of soils with piles and stamps belongs to the field of engineering surveys and is designed for static testing of soils with piles and stamps for indentation in the design and construction of buildings and structures. The installation consists of a jack, a thrust structure, anchors, a control system and displacement measurement sensors. The thrust structure is a dismountable, bolted, spatial structure in the form of a geodesic dome with a plate located in the upper tier and anchors located around the perimeter at the base of the installation; the thrust force from the jack is evenly distributed by the plate through the nodes of the geodesic dome over all its elements and is perceived by the anchors. The main advantage of using the new installation is to increase its mobility during transportation, installation and dismantling of all the main elements by reducing their length and weight. As a result, it becomes possible to conduct static tests of soils with piles and stamps in hard-to-reach and remote areas, without the use of large-sized construction equipment.

3D turbulent currents simulation in the coastal zone using the LES approach based on filtered ADCP data
Authors: Sukhinov Alexander , Protsenko Elena , Protsenko Sof’ya
Published: January 2023

The interest in turbulence in shallow waters, such as the Azov Sea, is caused by the fact that in the places of its existence there is an intensive transfer of the amount of motion and heat, the spread of passive impurities, the transfer of suspended particles. These processes significantly affect the formation and spatial structure of physical, chemical and biological fields of reservoirs and their spatial and temporal changes. Depending on the smoothing scale of the series of initial readings of the flow meters, the pulsation characteristics of the flow velocity were determined, which were processed in order to obtain data on turbulence and its scales. The research results provided empirical data on the conditions of generation and existence of small-scale turbulence. The collected empirical material is currently being processed to study the internal structure of the recorded disturbances of small-scale turbulence. In this paper, small-scale motion is excluded from the Navier-Stokes equations by applying the filtration operation and is modeled using subgrid models. To do this, in two-dimensional and three-dimensional cases, various types of filters are used: a box filter, a Gaussian filter and a Fourier filter, with a gradual decrease in the filter width, which allows you to reproduce a wider frequency range of fluctuations of the solution. The obtained data are planned to be used for numerical simulation of three-dimensional turbulent flows using the LES approach and comparison with the results of averaging by RANS. The article considers the possibilities of using various types of approximations for parametrization of vertical turbulent exchange. Algebraic models for calculating the coefficient of vertical turbulent exchange and semi-empirical turbulence models are compared.

Published: January 2023

Unmanned aerial vehicles are vehicles that can fly without a human pilot on board. Recently, unmanned aerial vehicles (UAV) have become widespread in the civil and military sectors, and the development of UAV is one of the promising trends in modern aviation. Drones have long ceased to be expensive and highly specialised and are in widespread use. They can be equipped with multiple cameras, gyrostabilisers, LIDAR and GPS to collect and transmit data in real time. Due to the demand for drones in various applications such as agriculture, search and rescue, wireless communications, surveillance and cargo transportation, several types of UAV have been invented with different sizes, weights, flight ranges, engine types, etc., optimized for specialized types of work. The deeper integration of drones into the transport system has the potential to relieve general strain in many companies and factories, reducing production and transport times, and facilitating faster response to emergencies. However, drones face a number of challenges related to flight logistics, collision avoidance, lack of necessary infrastructure, autonomous operation time and imperfect artificial intelligence.

Objectives To compare the efficacy of in-vivo and in-vitro stone
attenuation in the prediction of stone composition using non-contrast-enhanced abdominal
computed tomography (NCCT).

Methods This study included a total of 104 patients with renal
stones who received percutaneous nephrolithotomy treatment for renal stones between December
2016 and December 2019 and underwent NCCT before the procedure. Preoperative (in-vivo) and
postoperative (in-vitro) kidney stone attenuations were compared using the NCCT images of the
patients. Renal stone fragments were analysed with the infrared spectrophotometer
method.

Results The mean age of the 104 patients was 49.5 (interquartile
range: 37–61) years. According to the receiver operating characteristics analysis, the cut-off
values for the prediction of uric acid stones were determined to be 556 HU for the in-vivo and
774 HU for the in-vitro attenuation measurement. Sensitivity and specificity were 100% and
96.6%, respectively, for the in-vivo and 90.9 and 91%, respectively, for the in-vitro images.
The cut-off values for the prediction of calcium stones were determined to be 824 HU and 1065
HU for the in-vivo and in-vitro attenuation measurements, respectively. Sensitivity and
specificity were 97.3 and 96% for the in-vivo and 96 and 96% for the in-vitro images.

Conclusions In-vivo stone attenuation measurement in NCCT was
slightly superior to in-vitro measurement due to the reduction in the composition and size of
the stone. Our findings show that NCCT in-vivo stone attenuation might differentiate uric acid
and calcium stones from the other stone types.
Design, Synthesis and Biological Evaluation of Imidazole-Substituted/Fused Aryl Derivatives Targeting Tubulin Polymerization as Anticancer Agents

The development of new pharmacologically active molecules targeting tubulin polymerization has recently attracted great interest in research groups. In efforts to develop new potent anticancer compounds, imidazole-tethered/fused pharmacologically active aryl derivatives possessing different substitution patterns targeting tubulin polymerization have been rationally designed and synthesized. The target molecules (P1-5 and KG1-5) were synthesized by multistep syntheses involving the reaction of intermediate 2-aminophenyl-tethered imidazoles with appropriate reactants in the presence of p-TsOH under different conditions. The synthesized compounds displayed moderate to good cytotoxicity, comparable to that of colchicine, against four cancer cell lines (MCF-7, MD-MBA-231, A549, and HCT-116). Compounds P2 and P5, with an imidazoloquinoxaline moiety, emerged as potential leads with cytotoxicity profiles against these cell lines similar to colchicine. Compounds P2 and P5 arrested cell division at the G2/M phase and prevented cancerous cell growth through induced apoptosis. These results favored the hypothesis that the compounds might act by binding to the colchicine binding site, which was further confirmed with the help of a tubulin polymerization inhibition assay. The results encourage the further exploration of imidazoloquinoxalines as promising leads that deserve advanced clinical investigation.

Introduction Anosmia is one of the common symptoms of COVID-19, the link between severity of chest infection and anosmia was investigated by few studies.

Objectives To find an association between anosmia and severity of chest infection.

Methods An analysis of patients admitted to isolation hospital of our university with confirmed polymerase chain reaction positive testing for COVID-19, between March 2021 until September 2021. We called all patients who reported anosmia during their time of illness and asked them about anosmia. We examined their chest CT. A statistical analysis was done.

Results A total of 140 patients completed the study; 65% were female and 56.4% had complete anosmia. Anosmia was significantly associated with loss of taste. Smell returned in 92.5% of anosmic patients. Duration of smell loss was ∼ 2 weeks in 40.5%. The most common symptoms associated with anosmia were running nose, sore throat, fever, and cough. Loss of smell was significantly associated with mild chest disease. 73.4% of anosmic patients had mild chest infection, 21.5% of them had moderate infection, and 5.1% had severe chest infection.

Conclusion The pattern of anosmia in COVID-19 patients has some common similarities in general; the way it starts, the associated symptoms, the time until smell returns and, the most important, the severity of chest infection. As anosmia is significantly associated with mild chest infection. the presence of anosmia could be an independent predictor of good COVID-19 outcome as reflected by a lower disease severity and less frequent ICU admissions.
Exact thresholds for global existence to the nonlinear beam equations with and without a damping
Authors: Yuan Yiyin , Tian Shuai , Qing Jun , Zhu Shihui
Published: January 2023

In this paper, we study the Cauchy problem for focusing nonlinear beam equations with and without a damping term. By constructing two pairs of invariant flows, we obtain the exact thresholds for the global existence and blow-up to the above equations in the sense that both thresholds are explicitly expressed by the L2-norm of the fourth-order nonlinear elliptic equation without any damping.
Problems involving the fractional g-Laplacian with lack of compactness
Authors: Bahrouni Sabri , Ounaies Hichem , Elfalah Olfa
Published: January 2023

In this paper, we prove compact embedding of a subspace of the fractional Orlicz–Sobolev space Ws,GRN consisting of radial functions; our target embedding spaces are of Orlicz type. In addition, we prove a Lions and Lieb type results for Ws,GRN that works together in a particular way to get a sequence whose weak limit is non-trivial. As an application, we study the existence of solutions to quasilinear elliptic problems in the whole space RN involving the fractional g-Laplacian operator, where the conjugated function G̃ of G does not satisfy the Δ2-condition.

Published: January 2023

In the first part of this paper, we generalize the Dirac reduction to the extent of non-local Poisson vertex superalgebra and non-local SUSY Poisson vertex algebra cases. Next, we modify this reduction so that we explain the structures of classical W-superalgebras and SUSY classical W-algebras in terms of the modified Dirac reduction.
