Published: December 2021

Abstract
Underwater video regulation is an insightful research field that can help engineers with bettering investigation on the lowered condition. Submerged video preparing has been utilized in a many fields, such as submerged infinitesimal location, landscape examining, mine identification, media transmission connections, and self-proficient lowered vehicles. Be that as it may, submerged video experiences solid assimilation, dissipating, shading contortion, and clamor from the manufactured light sources, causing video obscure, cloudiness, and a somewhat blue or greenish tone. In this way, the improvement can be separated into two techniques, submerged video de-preliminaries and underexposed video concealing remaking. Relentless in remote correspondence structures, for instance 3G, 4G, and so on, a coming crisis is endless deftly of the nonattendance of consistently Radio Frequency (RF) resources; this deterrent in moving speed cannot strengthen the improvement notable for high information speed. So the new innovation of Light-Fidelity (Li-Fi) came into picture. This innovation can be contrasted to that of Wi-Fi and offers points of interest like expanded available spectrum efficiency, effectiveness, security, low idleness and a lot higher speed. Communication is accomplished by exchanging light-emitting diode (LED) lights on and off at a speed higher than what is detectable to the human eye. This paper presents the explanation behind underexposed picture corruption and surveys the cutting-edge knowledge calculations like video reduce hazing algorithm. In this calculation, it uses two different de-hazing methods, simple Dark Channel Prior (DCP) and Approximate Dark Channel Prior (ADCP), to reduce haze in a video.

Published: December 2021

Abstract
As an indispensable complement to an integer vortex beam, the fractional vortex beam has unique physical properties such as radially notched intensity distribution, complex phase structure consisting of alternating charge vortex chains, and more sophisticated orbital angular momentum modulation dimension. In recent years, we have noticed that the fractional vortex beam was widely used for complex micro-particle manipulation in optical tweezers, improving communication capacity, controllable edge enhancement of image and quantum entanglement. Moreover, this has stimulated extensive research interest, including the deep digging of the phenomenon and physics based on different advanced beam sources and has led to a new research boom in micro/nano-optical devices. Here, we review the recent advances leading to theoretical models, propagation, generation, measurement, and applications of fractional vortex beams and consider the possible directions and challenges in the future.

Published: December 2021

Abstract
Cobalt, nickel, and their mixed hydroxides were electrochemically deposited on polythiophene-coated carbon-cloth substrate to develop new pseudo-capacitive electrodes for energy storage devices. Thiophene was electro-polymerized on carbon-cloth by the potentiodynamic method in acetonitrile containing 1-butyl-2,3-dimethylimidazolium hexafluorophosphate ionic-liquid as supporting electrolyte. The scanning-electron-microscopy images imply that flower-like Co(OH)2 microstructures deposited on bamboo-like polythiophene coatings on carbon-fibers but they are covered by net curtain like thin Ni(OH)2 layer. The Co-Ni layered-double-hydroxide deposited from their equimolar sulfate solutions is composed of large aggregates. The electron-dispersive-spectrum exhibits that Co/Ni ratio equals unity in the layered-double-hydroxide. The capacitances of Co, Ni, and Co-Ni hydroxide-coated PTh electrodes are 100, 569, and 221 F/g at 5 mA/cm2 in 1 M KOH solution, respectively. Their corresponding oxides obtained by calcination at 450 °C in de-aerated medium possess higher capacitance up to 911, 643, and 696 F/g at 2 A/cm2. The shape of cyclic-voltammetry and galvanostatic-charge-discharge curves, as well as the Nyquist plots derived from electrochemical-impedance-spectroscopy measurements, reveal that hydroxide coatings on the polythiophene-coated carbon-cloth are more promising electrode materials for supercapacitor applications. The mixed hydroxide-coated electrode shows good cyclic stability of 100% after 400 cycles at 5 mA/cm2.
Mesopore silica effect on chemical, thermal and tribological properties of polyimide composites
Authors: Poyraz Bayram , ÜNAL Hüseyin , Dayı Mustafa 
Published: December 2021

Abstract
In this experimental study, the effects of mesoporous silica filler content on the chemical, thermal and tribological properties of polyimide composites were investigated. For that purpose, Pi/mesoporous silica composites were produced by in situ polymerization with various mesoporous silicas. After fabrication, thermal stability and chemical characterization were determined using TGA and FTIR. Morphological alterations were monitored with a scanning electron microscope (SEM). Texture structure (pore size and pore volume) were determined by the BJH method. Friction and wear properties were investigated by using a pin-on-disc arrangement. At the end of the study, minor shifts of Pi/mesoporous silica composites were observed. Thermal stability, as well as pore size and pore volume, was decreased with mesoporous silica. The coefficient of friction and specific wear rate decreased with the addition of mesoporous silica. Abrasive wear behaviors were seen for both neat Pi and Pi–Si composites. Hence, this study evidenced that the properties of Pi are influenced by mesoporous dimensions and content of Si employed.

Published: December 2021

Abstract
Tamusu area is the primary pre-selection site of clayrock disposal repository for high-level radioactive waste (HLW) in China. However, the research on the migration behavior of nuclides in Tamusu clayrock is still in its infancy. For the first time in laboratory, the diffusion behavior of Re(VII) in Tamusu clayrock core was studied by means of through-diffusion method. The effects of pH, ionic strength and humic acid on the diffusion behavior of Re(VII) in clayrock were studied. The effective diffusion coefficient, apparent diffusion coefficient and rock capacity factor value were obtained. All the experimental conditions of Re(VII) diffusion in Tamusu clayrock are compared with other geological samples under the same conditions in literature data. The diffusion mechanism of radionuclide in Tamusu clay is discussed, which can provide experimental data for site selection and safety assessment of high-level radioactive waste repository in China. The experimental results showed an effective application and reference for the countries disposed HLW in mudrocks or clayrocks, such as France, Belgium etc. in Europe. Moreover, this research can provide the original data support for the metallogenic regularity and prospecting prognosis of rare element rhenium in different geological environments.
Behavioral Biases and the Law
Authors: Luppi Barbara 
Published: December 2021

Abstract
Empirical and experimental evidence shows that individuals exhibit behavioral biases in their decision-making processes that depart from the full rationality paradigm. This paper discusses the effectiveness of alternative debiasing strategies, designed to induce socially preferable outcomes. Following Jolls, C. and Sunstein, C.R. (2006). Debiasing through law. J. Leg. Stud. 35: 199–242, this paper examines legal strategies that aim at “debiasing through law”, attempting to reduce or eliminate boundedly rational behavior. Alternatively, policymakers can implement “insulating” legal strategies that separate the outcome from the biased behavior, without attempting to eradicate behavioral biases from the decision-making process. This paper compares these strategies in many areas, such as tort law, consumer safety law, and property law.
Intensification for discursive evaluation: a corpus-pragmatic view
Authors: Pan Yun 
Published: December 2021

AbstractThe phenomenon of intensification is pervasive in natural language use. Previous research has extensively discussed what intensifiers are and how they are associated with semantic developments. Corpora prove to be a useful tool to examine the semantic dimension of intensifiers. What has been overlooked, however, is the internal structure(s) of meaning conveyed by “intensifier + adjective” constructions in naturally occurring text and speech. The semantic relationship between the intensifier and the modified adjective needs to be made more explicit to address the pragmatics of intensification. Using BNC Sampler (a part-of-speech tagged corpus of general English) this study examines the most frequently used adjective intensifiers in both written and spoken discourse. Concordance lines generated for the adjective intensifiers are used to illustrate evaluative expressions in context. The observation contributes to debates on the pragmatics of intensifiers for evaluative meaning construction and transmission.
A New Apparatus for Shear-Seepage Testing at the Clayey Soil-Structure Interface

Abstract
In high earth-rockfill dams, large shear displacement exists in the contact area between the earth core and the concrete cushion at the bottom and on both sides of the banks of a river valley. Exposed to a high hydraulic gradient, seepage erosion is likely to occur in this area. A practical measure is to compact a thin layer of clayey soil with high plasticity such that it lies between the earth core and the concrete cushion. It is crucial to evaluate the capabilities of a clayey soil for this thin layer. A new apparatus modified from a conventional triaxial apparatus is developed to test the seepage characteristics of the clayey soil-structure interface under large relative shear conditions. Compared to the previous device, the new device can achieve a larger relative shear displacement that is closer to the actual condition while providing stress and a seepage state with a simple testing procedure. This apparatus consists of a soil-structure model, a vertical loading system, two back-pressure systems, and a monitoring system. The vertical loading system allows the soil-structure displacement to develop at a constant speed. Two back-pressure systems can simulate the high hydraulic gradient and the consolidation state of the specimen. The monitoring system automatically records the force load, the volume of water outflow, and the volume change in the pressure chamber. Basic tests and shear-seepage tests were conducted using this device to validate its efficiency and reliability. The results indicate that the permeability of the soil-structure interface decreases with the shear displacement over a large range. A finite element (FE) analysis was carried out to reveal the strain-stress and seepage state inside the specimen to explain the seepage mechanism.
Prior Criminal Offense As A Prerequisite For Secondary Criminal Activity
Authors: Mikish A.S. 
Published: December 2021

In recent years, the legal literature has begun to use the concept of secondary crime, which has long been used in German criminal law and is based on the theory of involvement in a crime. An analysis of the domestic criminal law literature suggests that this concept has not yet been sufficiently disclosed by anyone. It should be noted that the problems of involvement in the crime are given much less attention than, for example, complicity. This can be explained by the fact that involvement is considered by individual scholars within the institute of complicity.
The term «preceding» is intended to emphasize the fact that the commission of the main elements of a criminal offense is not possible without a previous, simultaneous or subsequent actual commission, or without a previously formed intention to commit another criminal offense. In this regard, it should be noted: speaking of «precedence», we do not mean strictly temporal dependence, when one action objectively precedes in time another, and mental-logical dependence, when one action or actually precedes another, or on at least exists in the plan to commit the latter. The previous crime is not part of the main structure of the criminal offense, remaining an independent component. Such a criminal offense only complements the feature of the main criminal offense with a special meaning, narrows it and thus describes, although in itself does not turn into a feature of this composition of the main criminal offense.
The Subjective Side Of Criminal Offenses In The Field Of Public Procurement
Authors: Cheredarchuk A.M. 
Published: December 2021

In this article, the author analyzes the subjective side of criminal offenses related to public procurement. It is determined that the state is the victim of a criminal offense, because it is it that does not get the result it expected when allocating budget funds. First of all, the reputation of the state itself, its state institutions is lost, the level of public distrust in public authorities increases, and so on. With this in mind, the guilt of the subjects of criminal offenses related to public procurement lies in the form of intent. The article proves that the guilt of criminal offenses in the field of public procurement is characterized by the fact that individuals commit such acts quite consciously, but often do not fully or partially admit their guilt. For the most part, the guilt of the investigated criminal offenses takes the form of direct intent, and can sometimes be combined with a selfish motive.
The purpose of a criminal offense in the field of public procurement is manifested in the desire of the perpetrator to achieve certain harmful consequences. Purpose, as well as motive, is an optional feature of the subjective side of the criminal offense. The peculiarity of the purpose, as a sign of the composition of a criminal offense, is that such criminal offenses, which are committed for a specific purpose, are committed exclusively with intent.
The purpose of a person who commits a criminal act in the field of public procurement as enrichment can be different - both specified (obtaining a specific desired property) and blurred (to improve their unsatisfactory financial situation, etc.). The purpose of committing such criminal offenses may be obvious or hidden. Thus, we can conclude that the purpose of the criminal offenses we investigate clearly follows from the nature of the act.
Unilateral Refusal Of A Lease Agreement: Theoretical And Practical Aspects
Authors: Polnyi D.A. 
Published: December 2021

The article deals with the unilateral refusal of a lease agreement as a way of self-defence of the tenant's and landlord's rights. The author expresses an opinion that unilateral refusal of a lease agreement by the tenant or landlord in cases provided by law or the agreement itself as a consequence of violation of the terms of a lease agreement should be considered is a sanction for illegal behavior of the parties of the agreement.
The author notes that unilateral refusal of a lease agreement in case of breaching the agreement by the other party should not be equated to termination of a lease agreement at the request of one of the parties. They are independent grounds for termination of the agreement, which are characterized by a different mechanism of implementation, for example, the termination of a lease agreement at the request of one of the parties is always carried out in court.
The analysis of case law shows that in order to be able unilaterally refuse from the lease agreement, when concluding an agreement it is necessary to state with a due precision the grounds for unilateral refusal for each party to the agreement.
The author draws the conclusion that the simplified mechanism of unilateral refusal of a lease agreement should include two general stages: the emergence of grounds for unilateral refusal, and proper notification of the other party about the refusal of the agreement.
The Concept Of Unfair Contract Terms
Authors: Harhat I.M. 
Published: December 2021

The article explores the concept of «unfair terms contract terms» through the analysis of its origin and fixing in the legislation and legal literature of the European Union, Ukraine and the United States. Comparisons of interpretations of this concept according to Directive 93/13/EEC, Model Rules of European Private Law, The Uniform Commercial Code, as well as the Law of Ukraine «On Consumer Protection».
In the article author notes that the definition of unfair terms of the contract is a complex symbiosis of material and procedural, a combination of justice and dishonesty, comparison of signs of «imbalance of interests» and «significantly disadvantaged» and therefore at this stage of civil law is not can be defined unambiguously.
It is investigated that the modern civil legislation of Ukraine is still in solidarity with the legislation of most EU member states in terms of introducing this concept primarily to protect consumer rights.
Regarding the definition of «unfair terms», author notes that Ukrainian legislation follows common legal trends and recognizes unfair terms when they violate the principle of good faith and fairness, as well as when they lead to a significant imbalance of contractual rights and obligations of the parties and harm the consumer.
As a result, it was found that in general the concept of «unfair terms» is evaluative and can not by its very nature reflect the motives laid down in the contract by one or another party. The Court of EU and the courts of the EU member states do not give general conclusions on a case-by-case basis, using the definitions contained in the text of Directive 93/13/EEC, which set out the conditions that may be considered unfair.
Author proposes to use the sign «significantly unfavorable position» proposed by A.A.Leff to define the concept of «unfair terms of the contract», as it will improve the protection of the interests of the economically weaker party in the contract.

Published: December 2021

Implementation of an effective policy in the field of medical means circulation at the present stage of the development of Ukrainian society is one of the defining conditions for its further democratic reform, strengthening in the country of the institutions of the rule of law, competitive market economy, ensuring the implementation of human and citizen rights and freedoms.
Any policy becomes understandable when it is understood who carries out it and what it is aimed at, i.e. defined subjects and objects of policy in society at one or another stage of historical development. This definition makes it possible to clarify the essence of political relations between subjects, as well as between subjects and objects of policy, to reveal the forms of their political behavior, methods of political activity, means of transformation of the political environment.
The article highlights the issues concerning subjects that form the general state policy in the field of circulation of medicines. Their analysis is carried out and their main functions and tasks are determined.
The state policy in the sphere of circulation of medicinal products is formed and implemented by the Verkhovna Rada of Ukraine, the President of Ukraine, the Cabinet of Ministers of Ukraine, the Ministry of Economic Development and Trade of Ukraine, the Ministry of Health of Ukraine, the State Service of Ukraine for Medicinal Products, professional associations of pharmaceutical workers, within the powers of which is the adoption of different types of normative legal acts (concepts, programs, provisions, procedures, rules, standards, instructions, instructions, licensing conditions, lists, codes, etc.), agreed with European and international legislation, as well as, if necessary, with other central bodies of executive power. Such standards follow, in addition to general normative legal acts, also from specialized acts on the formation of such policy.
