One of the features of a mature society is the existence of a perfect system of legal regulation. To have a solid system of legal regulations, students need to be trained beforehand, to make them prepared for the world of practice. The purpose of the article is to theoretically substantiate the problem of educating the legal culture of students, to contribute to solving legal problems. The basis of such a system is the high level of legal culture of the members of this society. In order to build a rule-of-law state, for the successful socio-economic development of the country, it is necessary to educate an active young man with a developed sense of justice.The study analyzes a series of student responses that were collected through interviews. In addition, comparative data were revealed in the study using methods such as thematic analysis.As a result of the experimental work, the level of students' legal culture and comparative data on the development of students' legal culture were revealed.   Keywords: education; law; legal culture; society; student; upbringing,

Argumentative competence, written or oral argumantation skills are essential in the process of academic non-academic communication. Raising this competence is of particular importance in the education process, which ultimately focuses on promoting the development of general, intercultural communication and stratehic learning skills.The competence to create an argumentative text is complex and includes different dimensions, which means the selection, construction, grouping of arguments, the proper conduct of argumentative reasoning. The systematization of the various concepts and respectives contained in it allows the arguments to be divided into two groups: speaker-oriented and interaction-oriented.Argumentative discussions and organized discussions processes generate discourse that is equated with the notion of community. Argumentation from the perspective of discourse analysis is a discource practice, which is realized in a specific context (contextualized), arises interactively, develops, models and is perceived by the participants in the interaction as argumentation. Strategic reasoning skills, as a discourse practice, instill in everyone in a particular society, in a particular discourse area, mandatory and important knowledge for all and form a solid system of thinking that ultimately leads to reasoned discussions processes.

The influence of a friction hysteresis on the self-exciting in a particle-solid-system will be investigated by experiments and a numerical model. For this, a test rig will be presented. This test rig allows to measure the actual acting friction force. Furthermore, a numerical model will be presented which has a differentiation between a time-dependent friction behavior in sliding and sticking. Bigger differences can be observed in the system behavior – even with a quality similar curve of the measured friction hysteresis. For example, in a system with PVC-W particles exists a sharp boundary between an area of stable stick-slip oscillation and an area of subsiding oscillation. In comparison to this, a system with PMMA particles has a smooth transition region between these two areas. The followed simulation studies shown, that the selfexciting mechanism is a complex interaction between the time-dependent behavior during the sliding and sticking and the external average system velocity.

Pertamina Hulu Mahakam (PHM) has applied the Mono Trip Gas Lift (MTGL) completion technique with 27 wells that have been completed by drilling rigs. To improve efficiency, PHM assigned a Hydraulic Workover Unit (HWU) in September 2020 to execute the first rig-less MTGL in the Mahakam field, which is economically feasible based on an internal study. Since HWU has never performed the MTGL cementing, some collaborative works must be done to identify backlog and establish solid procedures for perfect execution. Besides, top of sediment (TOS) was found 16-21 m inside the tubing, which hindered access to the most bottom production zones. Moreover, this project is the first MTGL conducted inside a 7” casing which allows a maximum of 3 barrels per minute (bpm) flow rate (according to packer specification). The flowrate limitation could potentially create higher TOS inside the tubing. Hence, we agreed to utilize a 3.5” landing joint and to apply a higher flow rate for displacing cement as per simulation with rigorous risk assessment and mitigations. As a result, the job was completed in 11.6 days without a lost-time injury, contributing to 12% PHM saving, while the TOS was tagged 13 m above the top of the landing collar by 1.9” macaroni. Despite its success, some lessons are captured as our recommendations, such as improving the sweeping efficiency of the MTGL wiper plugs, establishing a solid system for vital data of cementing job, and developing the infrastructure by HWU contractor to perform the job more successfully. This paper strongly recommends the rig-less operation as an alternative way to reduce the costs of well construction activity. A proper operation can be achieved by learning the lessons, closely managing and monitoring entire job stages. Finally, it encourages partnership and synergy for a better result.

A rigorous mathematical model was developed for a complex liquid-liquid-solid system in a batch reactor. The approach is general but particularly well applicable for the indirect epoxidation of vegetable oils according to the concept of N. Prileschajew. The model considers intra- and interfacial mass transfer effects coupled to the reaction kinetics. The liquid phases were described with chemical approach (aqueous phase) and a reaction-diffusion approach (oil phase). The oil droplets were treated as rigid spheres, in which the overall reaction rate is influenced by chemical reactions and molecular diffusion phenomena. The model was tested with a generic example, where two reactions proceeded simultaneously in the aqueous and oil phases. The example (i.e. fatty acid epoxidation à la Prileschajew) illustrated the power of the real multiphase model in epoxidation processes. The proposed modelling concept can be used for optimization purposes for many applications, which comprise a complex water-oil-solid catalyst system.

With the touchy development of information, the multi-see information is broadly utilized in numerous fields, for example, information mining, AI, PC vision, etc. Since such information consistently has a perplexing construction, for example numerous classes, numerous viewpoints of portrayal and high measurement, how to detail a precise and solid system for the multi-see order is an exceptionally difficult assignment. In this paper, we propose a novel multi-see characterization technique by utilizing various multi-class Backing Vector Machines (SVMs) with a novel shared system. Here each multi-class SVM installs the scaling component to renewedly change the weight assignment, everything being equal, which is useful to feature more significant and discriminative highlights. Besides, we receive the choice capacity esteems to incorporate different multi-class students and present the certainty score across various classes to decide the last characterization result. Moreover, through a progression of the numerical derivation, we connect the proposed model with the reasonable issue and address it through a rotating emphasis improvement strategy. We assess the proposed strategy on a few picture and face datasets, and the test results exhibit that our proposed technique performs better compared to other cutting edge learning calculations.

AbstractSelf-nanoemulsifying drug delivery systems (SNEDDS) were used to enhance the dissolution rate of furosemide as a model for class IV drugs and the system was solidified into liquisolid tablets. SNEDDS of furosemide contained 10% Castor oil, 60% Cremophor EL, and 30% PEG 400. The mean droplets size was 17.9 ± 4.5 nm. The theoretical model was used to calculate the amounts of the carrier (Avicel PH101) and coating materials (Aerosil 200) to prepare liquisolid powder. Carrier/coating materials ratio of 5/1 was used and Ludipress was added to the solid system, thus tablets with hardness of 45 ± 2 N were obtained. Liquisolid tablets showed 2-folds increase in drug release as compared to the generic tablets after 60 min in HCl 0.1 N using USP apparatus-II. Furosemide loaded SNEDDS tablets have great prospects for further in vivo studies, and the theoretical model is useful for calculating the adequate amounts of adsorbents required to solidify these systems.

In this work, the diffusion equation for the gas-solid system is revised to describe the non-uniform distribution of hydrogen in steels. The first attempt to build a theoretical and general model and to describe the diffusion process as driven by a chemical potential gradient is made. A linear elastic solid body and ideal gas, diffusing into it, are considered. At this stage, we neglect any traps and non-linear effects. The coupled diffusion-elastic boundary problem is solved for the case of the cylinder under the tensile loads. The obtained results correspond to the experimental ones. Based on them, the assumptions about the correctness of the model and its further improvement are suggested.
