Giving in the form of a certificate itself aims provide legal certainty and legal protection for the owner of the land object. The obstacles faced are the boundaries of the soil parcels that are not in appropriate with the ready-made certificate. The conclusion of the implementation of land registration of ex-ulayat land in Pemalang Regency is registered by the village government through the Complete Systematic Land Registration program.
La anarquía internacional y la teología política: reformulando el legado de Thomas Hobbes
Authors: Bain William , Cabero López María
Published: November 2022

El concepto de anarquía es uno de los más importantes en la teoría de las Relaciones Internacionales. Por ello, se recurre a menudo a Thomas Hobbes para ilustrar el carácter y las consecuencias de la anarquía. El presente artículo se cuestiona acerca del aspecto teológico de la filosofía política de Hobbes en un intento de superar la mitología distorsionada que se ha creado entorno a las relaciones internacionales “hobbesianas”. De este modo, se avanza hacia un argumento positivo que presenta a Hobbes como un teórico de una sociedad interestatal que se forma y deforma al igual que Dios creó el universo. El concepto de anarquía que se atribuye a Hobbes se basa en una disputa teológica sobre la naturaleza de Dios y la magnitud de su poder, lo que supone una forma específica de constituir y comprender la realidad. Cuando se consideran las implicaciones de dicha disputa, se demuestra que la anarquía no es ni una característica objetiva de un mundo compuesto por estados independientes ni una condición lógica inevitable que sigue a la ausencia de una autoridad central. Más bien, la anarquía es un logro del pensamiento, que nace en un momento y lugar determinado y que busca un reflejo de sí mismo en el espejo de la eternidad.

La regulación del refugio y el método feminista: la necesidad de una aproximación crítica
Authors: Zamora Gómez Cristina M.
Published: November 2022

En este artículo se pretende plasmar cómo a través de un enfoque metodológico feminista desarrollado desde las doctrinas iusfeministas, el análisis del Derecho Internacional de las Personas Refugiadas deviene en una regulación androcéntrica del mismo. El objetivo último es demostrar cómo a través de la aplicación del enfoque iusfeminista se pone en evidencia que las experiencias de refugio de las mujeres están marcadas por la violencia de género que sufren tanto en origen, en su trayecto como en el Estado donde solicitan ser reconocidas bajo el estatuto de protección y que esta realidad no está contemplada por el Derecho Internacional de las Personas Refugiadas. De este modo, el artículo mostrará, en primer lugar y con detalle, cuáles son las premisas del método feminista. Así, se hará un repaso de los estándares que señala el conocimiento situado, el método feminista, los aportes del feminismo postcolonial y, por último, la perspectiva interseccional. Tras este primer punto, en segundo lugar se presenta cuál es el resultado de aplicar los valores del método feminista a la regulación del Derecho Internacional de las Personas Refugiadas, así, en este apartado, expondremos en primer lugar el androcentrismo que padece la Convención de Ginebra de 1951 sobre el Estatuto de las Personas Refugiadas, pasando a continuación a señalar la evaluación que en el Derecho Internacional de las Personas Refugiadas ha tenido el sujeto «mujer» y/o «femenino», pasando de concebirse como sujetos vulnerables a sujetos subordinados y discriminados. Finalmente, se conceptualizará la «violencia de género» para lo que nos apoyaremos en diferentes instrumentos regulatorios internacionales de soft law en materia de igualdad de género. Por último, a modo de conclusión, se señalará cómo afecta dicha violencia de género en las experiencias de refugio de las mujeres, pudiendo constituir bien una forma determinada de persecución o bien siendo el motivo último por el cual están siendo perseguidas.
The Post-Pandemic Changes of Dark Tourism Industry
Authors: Radzevičius Martynas
Published: November 2022

Dark tourism is a segment of tourism that has been growing in recent decades and is strongly associated with tragedy and mystery. As a result, 2020 was strongly marked by the pandemic of the new coronavirus (COVID-19). This paper presents a reflection on the role of dark tourism in the pandemic and post-pandemic period and analyses impact of the COVID-19 pandemic on tourism industry. The paper discusses the global context of the pandemic situation that has an important impact on re-directing and tracing eventually new tourism trajectories of the (post)pandemic time. The shift that occurred in pandemic time are like catalysts for re-enforcement and raised interest into slow movements and ‘new normal’ tourism. Instead of seeking to ‘go back to business as usual’, the author argues to reconsider the trajectories that emerged during the time of the pandemic and to envisage other approaches towards more sustainable tourism.
Stress Factors Among Grade 2 Teachers: Links to Classroom Activities and Teacher Interaction Styles
Authors: Šilinskas Gintautas , Raižienė Saulė
Published: November 2022

This study involved a comparison of the prevalence of two work-related stressors (job-related issues and information and communications technology [ICT] use) and three situational stress factors (COVID-19, geopolitical concerns, and economic conditions) among 40 Grade 2 teachers in Lithuania. Also investigated were associations between the stress factors, the frequency of classroom activities (literacy and mathematics), and teacher interaction styles (affection, behavioral, and psychological control). A total of 40 Grade 2 teachers answered online questionnaires in April–May 2022, a period defined by the ongoing COVID-19 pandemic and the recent (2–3 months prior) start of the Russo–Ukrainian war. The results showed that, of the five stress factors examined, the highest levels of stress expressed by teachers were related to the geopolitical situation, which scored significantly higher than work-related stress factors (job-related issues and ICT use). The results also indicated that all stress factors except geopolitical situation were associated with behavioral and psychological control, suggesting that teachers who report higher levels of stress apply more controlling interaction styles when teaching their second graders. Moreover, the findings revealed that the frequency of classroom activities and the positive dimension of the interaction style of teaching (i.e., affection) were not related to any of the stress factors.

An experimental stand was created to study the thermobaric and chemical influence of hydrogen on the identification of hydrocarbon production. The said stand allows to reproduce chemical-technological processes as close as possible to real formation ones. This stand makes it possible to study the kinetics of not only hydrogen, thermobaric and chemical effects, but also other thermal gas chemical processes, including hydrogen generation. The main element of the experimental stand is a hydrogen generator, the components of which work at high pressures and temperatures under conditions of hydrogen embrittlement of mechanical properties and an aggressive environment that causes corrosion of its inner surface. Based on this, the development of a methodology for calculating the thermal stress state of the generator, its strength under hydrogen embrittlement conditions, and its resource becomes relevant. Based on the finite element method, a methodology for calculating non-stationary temperature fields and the thermal stress state that occur in the hydrogen generator during thermobaric and chemical processes of varying intensity is proposed. The methodology allows to take into account the features of the geometry of the structure, the time-varying temperature and pressure distributions of the reaction products, the temperature dependence of the thermophysical and mechanical properties of the hydrogen generator material. Thanks to the application of the developed software, a study of the hydrogen generator thermal stress state during two real thermobaric and chemical processes of different intensity was carried out. Graphs of temperature and pressure changes of the reaction products of hydroreactive substances in the generator over time, which were registered during the experiment conduction, were used. The distribution of non-stationary temperature fields and stresses in the hydrogen generator elements was obtained. Areas of maximum load of generator elements are defined. It was established that during the flow of the studied thermobaric and chemical processes, pressure makes a greater contribution to the thermal stress state. The obtained results and the developed theory and software can be used in the study of generators of other designs with other thermobaric and chemical processes occurring in them.

The results devoted to the issues of energy-ecological assessment of industrial boiler equipment with jet-niche combustion technology are given in the paper. The basic principles underlying this technology include: rational distribution of fuel in the oxidant stream; stable adjustable structure of fuel, oxidant and combustion products; self-regulation of the fuel mixture composition in the zone of the torch stabilization when the unit load changes. As of today, a large number of industrial gas-burning equipment has been modernized by jet-niche technology, including: boilers, furnaces, dryers, metallurgical facilities, etc. The results of industrial implementation of the technology allowed to accumulate a significant amount of technical information and gave the possibility of preliminary environmental assessment during the modernization of gas combustion equipment. As practice shows, at the present stage the main direction of the technology improvement is to enhance its environmental performance. The influence of the main regime and technical parameters of fire equipment on its emission indicators is established in the paper. Possibilities for reducing nitrogen oxides by primary technological methods, the simplest and most effective of which is the introduction of recirculation gases into the furnace space, have been identified. According to the results of the analysis of emission indicators of the modernized fire equipment with a capacity of 0.5–60 MW, data to estimate the emission indicators of low and medium power boilers depending on the main influencing factors, namely, unit size, excess air ratio and boiler load were obtained. The influence of the introduction of recirculation gases into the furnace space on the level of nitrogen oxides concentration is also taken into account. The efficiency of application of the recirculation gases introduction scheme into the primary air flow in comparison with combustion technologies based on vortex burners is shown. According to the results of the industrial experiment, the energy efficiency of the proposed measures was established on the example of the dependences of efficiency on the load of boilers PTVM-50 and KVGM-20.

Woman Hymns and Christian Songs: Analysing women’s marginalisation in Kidung Jemaat
Authors: Cambah Tahan Mentria , Sari May Linda
Published: November 2022

Singing is a tool used by Christians to worship. The song forms the attitude of its adherents by following the verses contained in the song. This paper aims to analyse the Kidung Jemaat song used by Christians in Indonesia using the lens of feminist theology. The dominance of the patriarchal concept causes an imbalance in relations between society and the church. The research was carried out by qualitative research, observing and carefully reading the poems used by the church in general, especially Kidung Jemaat. The study found that church hymns mention very little about women's stories, whereas the Bible talks about women's ministry in the community. The people's attitude was formed over the years, causing women to be marginalised in Christian singing. As a result, women are also marginalised in worship in the church and community. The church needs to encourage church musicians to create women's songs in the church.

Published: November 2022

In locations where power is restricted, such as off-grid, solar, and generator-powered houses, considering the capacity of the power source is critical for the effectiveness of home automation systems. During regular power system outages, millions of houses all over the globe are reliant on a fixed current power supply to keep their lights on. In such circumstances, prioritizing and arranging the home's workload is essential. The goal of this paper is to decrease the amount of effort required by the user to manually control a gadget. To connect with the Raspberry Pi and the users, this system makes use of Google Assistant Software Development Kit (SDK), which is offered by Google. Users use voice commands to manage the devices in their homes, check the amount of current available, and chat to the Google Assistant to turn on/off the smart switch. This paper suggests using a sensor, Message Queuing Telemetry Transport (MQTT) protocol, a controller (OpenHAB open source), and an actuator in conjunction with each other (smart switch) has the capability of measuring and monitoring the entire power that is available and making choices based on that knowledge. Finally, the usage of Google Assistant as an artificial intelligence system makes end-user engagement with the smart home more pleasant. The proposed network was executed in both unlimited and limited power or electrical current modes to compare the standard unlimited smart home setup and our current control design. The system was programmed to function based on the proposed algorithm, with a 10 Ampere as a maximum available current. The water heater was considered a low priority load in this trial as a heavy load. In this system’s run, the smart controller was continuously monitoring the load, and when the total load reaches 10 Amperes or above it turns off the low priority loads. Thus, preventing the power supply overload.

The article contains an analysis of kazakhstan's path of development of the transport and logistics industry. The analysis of statistical indicators of the development of transport and logistics complex of Republic of Kazakhstan is presented, as well as the main directions of development of the industry.
This article considers aspects of the development of transport and logistics complex in the country, which depend on many factors, including different government support tools. As a result, in the Republic of Kazakhstan in 2021 the cargo turnover by modes of transport increased by 2.26 %, with stable indicators of cargo transportation by rail (accounting for more than half of the total cargo transportation), there is a significant increase in cargo transportation by pipeline transport − by 11.9 % and a slight decline in road transport − 1.06 %. In 2021, positive dynamics of cargo turnover by modes of transport has observed in Kazakhstan, which has increased by 4.96 %, it is caused by the increase of cargo turnover in three main directions: air transport − by 116.2 %, pipeline transport − by 21.4 % and road transport − by 11.93 %. It is proved, that low level of information and digital technologies and high physical and moral wear and tear of major part of infrastructure are key factors limiting development of transport and logistic complex.
These findings illustrate how the existence of laws and regulations governing the transport industry, as well as the favorable geographical location of Kazakhstan for the transit of goods along international transport corridors are important for the development of the transport and logistics complex of the Republic of Kazakhstan.
The practical application of the results of the study is the possibility of forecasting further directions of development of transport infrastructure
Determining experimentally the patterns of the manifestation of the Sommerfeld effect in a ball auto-balancer
Authors: Filimonikhin Gennadiy , Yatsun Volodymyr , Matsui Anatolii , Olijnichenko Lubov , Pukalov Viktor
Published: November 2022

This paper proposes an experimental method for studying the Sommerfeld effect in auto-balancers or exciters of resonant vibrations of pendulum, ball, or roller type. The method is based on the processing of signals acquired from analog sensors of rotations and vibration acceleration using regression analysis. The method is tested on a specially designed rotor bench on isotropic viscoelastic supports, which executes spatial motion, and an auto-balancer with one ball.
Checking the accuracy of the method using stroboscopic lighting demonstrates the accuracy of determining the speed of rotation of the rotor, ball, oscillation frequency of the rotor, etc. with an error of several hundredths of a percent.
When fixing the ball relative to the rotor, a classic inertial vibration exciter is obtained. The rotor has two resonant velocities. The Sommerfeld effect is almost not manifested. With a gradual increase in the frequency of the current, the rotor speed increases monotonously. There is no significant slip or jump in the rotor speed. There are two distinct peaks on the amplitude-frequency characteristic. Therefore, such a vibration exciter is not suitable for the excitation of resonant vibrations.
With the free placement of the ball in the oil, the behavior of the system changes significantly in the vicinity of the first resonant velocity. The first narrow resonant peak disappears in the roto. Instead, there is a long, gentle resonant rise. It lasts at a current frequency of 9.4 Hz to 19.3 Hz. The amplitude at the reference point on the resonant rise increases from 0.7 mm to 2.84 mm. Therefore, by changing the frequency of the current, it is possible to smoothly change the amplitude of the rotor oscillations by almost 4 times. The maximum amplitude of rotor oscillations is the same as at the first resonance with a fixed ball. Due to the gentleness of the resonant rise, a freely installed ball itself is a reliable exciter of resonant vibrations

The Covid-19 pandemic had changed the business model in various industries. Companies have switched to digital business processes in order to survive in this challenging situation. Financial Technology (Fintech), especially digital payment services, has become the most preferred solution for handling financial transactions in conditions of limited mobility and interaction. The phenomenal emergence of Fintech has captured the attention of the world and the Asian region, including Malaysia and Indonesia. Despite various benefits offered by Fintech, the adoption rate is still relatively low, especially for IT-savvy groups of fresh graduates in both countries. This comparative study aims to analyze the adoption of Fintech payment services in Malaysia and Indonesia using the UTAUT theory approach.
The research measures the relationships between performance expectancy, effort expectancy, social influence, consumers’ trust, and national culture with the adoption of Fintech. Each indicator of national culture, such as individualism, power distance, uncertainty avoidance, masculinity and long-term orientation, was measured to see its relationship with the adoption rate.
The quantitative method was employed, and the data were collected via an online survey of a total of 486 respondents. Using multivariate regression analysis, 57.9 % behavioral adoption of Fintech payment services both in Malaysia and Indonesia was explained through performance expectancy, effort expectancy, social influence, customer trust and national culture. The study revealed that performance expectancy and the cultural factor individualism had the highest effect on the decision to adopt digital payment services.

When solving many tasks related to mine workings, rock pressure management, development systems, support structures, the issues of strength and stability of rocks become relevant. Limitations and gaps are identified, emphasizing the need for further research and development of new methods for solving applied problems of elasticity theory.
It is of theoretical and practical interest to determine the influence of half-space geometry on the stressed state of the medium and to assess whether it would suffice, in this case, to confine oneself to radial stress when characterizing the stressed state. To build a mathematical model of the stressed state of the array, a complex variable function argument method was used. Based on the developed complex variable function argument method, the applied problem of mechanics on loading the wedge with a concentrated force in polar coordinates was solved.
A feature of the proposed approach is the introduction of tangential stresses with the need to meet boundary conditions along inclined faces. The introduction to the consideration of tangential stress shows that it cannot be neglected at a certain stage of the search for a solution. First of all, this is due to the half-space geometry, the angle at the apex, and the depth of the array. When changing the angle of the wedge, the interface surface changes fundamentally and can pass from a convex shape to a concave one. Simplification of the proposed expressions leads to a complete coincidence with the solutions by other authors obtained by the stress method, which indicates the reliability of the result reported here. This method may be advanced by complicating the half-space geometry, as well as loading, and by building a mathematical model for assessing the effect of tangent stresses on the strength and stability of soils

Nickel foam is widely used as a current lead/current collector and as the base of nickel hydroxide electrodes for hybrid supercapacitors. An investigation of the influence of activation conditions for a commercial sample of nickel foam produced by Linyi Gelon LIB Co Ltd (China) was carried out using the method of impact nickel plating. The morphology of activated and non-activated nickel foam samples was investigated by scanning electron microscopy. Activated and non-activated nickel foam samples were investigated by methods of cyclic voltammetry and galvanostatic charge-discharge cycling in the supercapacitor mode.
It was shown that upon activation at i=1 A/dm2 and τ=10 min, a thin layer of porous nickel with incomplete coverage was formed. Activation with impact nickel at i=7 A/dm2 and τ=3 min revealed the formation of a nickel coating with a highly developed surface, on which local cracks were found as a result of the accumulation of internal stresses. Activation with impact nickel at i=1 A/dm2 and τ=10 min led to the formation of a coating with a highly developed surface, with significant peeling of the coating.
Cyclic voltammetry showed high efficiency of impact nickel activation at i=7 A/dm2, τ=3 min, and i=20 A/dm2, τ=5 min. The specific current of the cathode peak increased 6.06–6.44 times with respect to the non-activated sample. The investigation of the activated samples' electrochemical characteristics by the galvanostatic cycling method showed that impact nickel activation at i=1 A/dm2 and τ=10 min was insufficient. It was found that at a discharge up to E=0 V, the maximum specific capacitance of 0.731 F/cm2 was obtained for samples activated by impact nickel at i=7 A/dm2 and τ=3 min. The increase in specific capacitance compared to the non-activated sample was 4.49 times. At full discharge, the highest electrochemical activity was found for nickel foam samples activated by impact nickel at i=20 A/dm2 and τ=5 min. The specific capacitance was 0.505 mA∙h/cm2, and it increased 9.02 times

The object of this study is the dynamics of hazardous parameters of the gas environment during the ignition of materials. The problem that was solved is the early detection of fires in the premises. The research results indicate the nonlinear nature of the dynamics of hazardous parameters of the gas environment in the absence and presence of materials ignition. It was established that the bispectrum amplitude, in contrast to the amplitude spectrum of the hazardous parameters of the gas medium, contains information on the reliable detection of fires. As such information, the value of the positive dynamic amplitude range of bispectrum is used. It was established that during the ignition of alcohol, the positive dynamics of the amplitude bispectrum of all dangerous parameters of the gas medium change. Significant changes are characteristic of smoke density (from 1 dB to 30 dB) and temperature (from 1 dB to 70 dB). The dynamic range of amplitude bispectrum for CO concentration is increased from 30 dB to 70 dB. Paper ignition was found to reduce the dynamic range of the amplitude bispectrum for smoke density from 40 dB to 20 dB. At the same time, the dynamic range of amplitude bispectrum for carbon monoxide concentration and temperature increases to 60 dB. The ignition of wood causes an increase in the dynamic range of the amplitude bispectrum relative to the concentration of carbon monoxide from 40 dB to 60 dB, and the temperature – from 30 dB to 40 dB. It was established that when textiles are ignited, the range of dynamics of the amplitude bispectrum for temperature increases from 10 dB to 60 dB. The results indicate that the dynamic characteristics of the amplitudes of the bispectrum of the gas medium can be used in practice for the early detection of fires in the premises
Identifying the influence of dimensional parameters on the stresses and deformations of two helical gears
Authors: Ahmed Bassam Ali
Published: November 2022

In this research paper, focusing on the basic variables of the gear modeling process and setting its dimensions to see which gears are capable of withstanding transmission operations and its rigidity was done. Because one of the most prominent transmission mechanics is gears, as the types of gears are numerous and common, and one of the most prominent types of gears is the helical gear. The helical gear is one of the most widely used and widespread gears in mechanical fields due to the increase in the contact area during the interlock process, as this increase reduces noise during gear rotation. Three main variables were used to establish the results. The first of which is the pressure angle, the helix deflection angle, and the module number, and they made a number of cases to see which one was able to withstand the movement operations with a proven torque. The results proved that the distortion value in the first case at module 1 was 87×10-6 m, while in module 2 the distortion value was 3.75×10-6. The data are useful and important because the values of the stresses that affect the gears must be known by changing the module due to it gives a stronger concept of the extent to which the gears can withstand movement. Pressure angle is one of the basic variables that change the dimensions of wind turbine gears. The value of the greatest stress was 2.13×108 Pa, but at the pressure angle of 20 degrees, the stress value was 1.93×108 Pa. It affects the diameter, stiffness and tensile strength of a wind turbine. The study of this research paper depends on helical gears. It is known that the angles of the helical teeth increase the large contact area between two gears. From the resulting deformation values, it is noted that the deformation value is 4.26×10-6 m when the helix angle is 20 degrees.

The use of layered double hydroxides (LDHs) is a new direction in chemistry of cement. The influence of calcium/aluminum double hydroxides (Ca-Al LDHs) and polycarboxylate ethers (PCE) on the strength development of Portland limestone cement has been investigated. It has been shown that Ca-Al LDHs form in cement slurry with the introduction of alkaline aluminate accelerator Na[Al(OH)4]. It was determined that this contributes to a significant increase in the early strength of cement stone. However, this reduces the setting time of hardening, and there is a decrease in strength with age. At an early stage of structuring in cement paste with the addition of Na[Al(OH)4], metastable high-water hydrate phases of Ca-Al LDHs of type C4AH19 ([Ca2Al(OH)6]2(ОН)2·12H2O) are formed, which, due to the conversion phenomenon, transform to cubic C3AH6. Such processes are accompanied by an increase in overall porosity and decreases in the strength of cement stone. Stabilization of the Ca-Al LDH structure is achieved by introducing anions [NO3]- into the interlayer space with the formation of Ca-Al-NO3 LDHs through the use of sol-gel technology. X-ray phase analysis, IR spectroscopy, and electron microscopy proved the fact of synthesis of AFm-phases of type [Ca2Al(OH)6]2(NO3)2.6H2О. When modifying such hydrates with polycarboxylate ethers, a nanocomposite Ca-Al-NO3 LDHs-РСЕ is formed. It was found that when the Ca-Al-NO3 LDHs-РСЕ nanocomposite was introduced to СЕМ ІІ/A-LL 42,5 R, the strength over the period of 8...24 hours increases by 2.0–1.5 times, and, after 2 and 28 days, 58 and 144 % of the standard strength is achieved (Rс28=62.5 MPa). The obtained nanomodified Portland limestone cement refers to extra rapid-hardening and high-strength cement, which makes it possible to solve the task of carrying out work on the rapid restoration of reinforced concrete structures' elements
