FACTORS PREDICTING PUBLIC PERCEPTIONS ABOUT THE IMPACT OF COMMUNITY ENLARGEMENT IN SETTLEMENTS OF RA

In 2022, the elections of local self-government bodies in the Republic of Armenia ended the process of community enlargement, which was started in 2011.The community enlargement process deviated several times from the initial implementation methodology, and was conceptually revised in 2018 after the velvet revolution. Currently, multiple deviations and changes from the prescribed approaches have created a situation where a number of communities have been enlarged using the pre-2018 methodology and the rest using the post-2018 methodology. As a result, there was no coincidence that complaints arose, especially among the population of small rural settlements related to the possible deterioration of the socio-economic condition of settlements, the weakening of local self-governance and the disproportionate increase of dependence on large settlements. Illegitimate communal enlargement implies an uncontrollable increase of mistrust among the population towards the policies implemented at the local level and those who implement them, which can lead to the disruption of public life. In this context, the lack of knowledge related to the public perceptions of the changes implemented in the enlarged communities, especially in the context of the discussed problems and the risks arising from them, makes the implementation of research aimed at clarifying the abovementioned issue more than relevant. In April-June 2024, a survey was conducted in the enlarged communities of RA, with the aim of identifying, in addition to a number of research problems, public perceptions of the impact of community enlargement in individual settlements and the factors affecting them. As a result of the ordinal regression analysis carried out in this context, it becomes clear that among a number of research variables, only social capital, place leadership and population dispersion index in enlarged communities meet the statistical assumptions for inclusion in the specified regression model. The odds ratios calculated in the later stages of the model construction show that in the case of social capital, place leadership and dispersion index, the transition to each next category increases the probability of recording positive perceptions of community enlargement among the population. Thus, the proposed hypothesis is also confirmed, according to which: Each 1-level increase in social capital, place leadership and dispersion index in enlarged communities increases the probability of recording positive perceptions of community enlargement impact among residents.

ANALYSIS OF THE RESULTS OF THE IMPLEMENTATION OF THE BAN ON THE SIMULTANEOUS INTRODUCTION OF POSITIVE REACTIVITY IN TWO OR MORE WAYS

The main reason for the prohibition of simultaneous injection of positive reactivity in two or more ways is the requirements of the nuclear safety rules for reactor installations. The introduction of positive reactivity by the means of influence on reactivity, provided for by the technical design of the reactor installation, should be excluded, if the emergency protection working bodies are not brought to the working position. Technical measures should exclude the possibility of introducing positive reactivity simultaneously by two or more provided means of influencing reactivity, as well as introducing positive reactivity by means of influencing reactivity during fuel loading and unloading. The rate of increase in reactivity by means of influencing the reactivity should not exceed 0.07 βef/s. For the working bodies of the control and protection system with an efficiency of more than 0.7 βef, the introduction of positive reactivity should be stepwise, with a step weight of no more than 0.3 βef (provided by technical measures). In the technical design of the RU, the size of the step, the pause between steps and the rate of increase in reactivity should be indicated. The consequence of introducing positive reactivity in two or more ways is a possible violation of the conditions for normal operation of nuclear power plants due to an uncontrolled increase in the neutron flux in operating and emergency modes of the reactor. The installed second-type warning protection, which is supposed to solve this problem, has shortcomings in its operation that lead to a clear violation of the current prohibition on the simultaneous introduction of positive reactivity in two or more ways. On the basis of the conducted research, the existing error in the operation of the PP-2 was identified and analyzed. To avoid the problem with the simultaneous introduction of positive reactivity in two or more ways, it is proposed to modernize the system of PP-2 with its further operation on reactivity indicators.

Numerical Investigation of Different Cooling Methods for Battery Packs

This paper contains the results of numerical investigations into two cooling system types for cells of three types. The galvanic cell geometries which were considered were pouches, cylinders and prisms. By design, the cooling system for a vehicle is specialised to prevent an uncontrolled temperature increase at higher discharge rates. Consideration was given to the question of which cooling method would be sufficient to reduce the temperature rise of battery cells. The first cooling method investigated is one that uses direct contact with the air flow to cool the cells, a method that is very commonly used in automotive engineering, as it is less complicated. This study employs a method that uses a fan to induce forced convection, increasing the airflow over cells housed within a thermoplastic composite container. Another method, fluid cooling, is notable for its greater efficiency due to the use of a non-conducting coolant, which has also better energy absorption properties. In this study, immersion cooling was employed, utilising oil circulation through cells contained within a thermoplastic composite container, which was facilitated by a pump system. This publication shows the influence of the cell’s geometry and the type of cooling system on the temperature rise of cells when they are discharging at the appropriate power rate. The results of this study highlight the differences in cooling performance between the two methods, providing a clear basis for selecting the most suitable solution for specific applications.

EFFICIENCY OF USING PORTABLE FIRE EXTINGUISHERS WHEN EXTINGUISHING LITHIUM-ION BATTERIES

The article substantiates the trends in using electric energy storage systems consisting of a battery, an inverter, connecting conductors, safety automation, and, if necessary, solar panels. Such systems typically use lithium-ion batteries because of several technical advantages: high specific energy capacity, high discharge-charging currents, and many charge-discharge cycles, i.e., longevity. The chemical and electrochemical reactions that occur during the charge-discharge cycles of lithium-ion batteries can lead to irreversible electrothermal processes. Such processes cause an uncontrolled increase in temperature, the release of hazardous gases, fires, and explosions, often accompanied by fire. Therefore, the authors conducted a successful full-scale field study of the effect of various extinguishing agents of the most common portable fire extinguishers in Ukraine on the efficiency of extinguishing lithium-ion batteries. Based on the experiment, we found that extinguishing the lithium-ion module using a portable carbon dioxide fire extinguisher is the least effective among the extinguishers studied, with the resumption of flame combustion occurring within 3–4 s after the cessation of carbon dioxide supply to the combustion centre. When using a portable powder fire extinguisher, the flame combustion of the test module resumed after 18–20 s. The desired extinguishing effect was achieved using low-density air-mechanical foam from the VVK-5 fire extinguisher and sprayed water with salt additives from a water extinguisher. Based on the obtained research results, we proposed recommendations for the selection of standards for the availability and use of portable fire extinguishers for the effective extinguishing of lithium-ion batteries at the rate of at least 5 kg of charge of working solution or water with salt additives per 5 kWh of energy capacity of a lithium-ion battery. Further research will identify influence patterns of the intensity of extinguishing agent supply on the efficiency of extinguishing lithium-ion batteries. Keywords: lithium-ion battery, fire, irreversible electrothermal process, fire safety.

The Impact of Economic Growth, Energy and Electricity Consumption Usage on CO2 Emissions: A Case Study of Morocco

Given the uncontrolled increase in environmental pollution and degradation of environmental quality worldwide, the environmental impact of economic growth has become a major focus in recent decades the most important question is: How does economic growth affect environmental quality? This study addressed this issue, examining the nature of the long-run relationship between economic growth per capita and pollutant emissions in Morocco. For this reason, the ARDL (Autoregressive Distributed Lag) modeling approach was used from 1990 to 2020. This approach mainly includes time series analysis and cointegration. The relationship tested introduces four variables: carbon dioxide (CO2), energy consumption per capita, electricity consumption per capita and GDP per capita. The main results indicate a long-term relationship between economic growth, energy consumption and CO2 emissions, indicating that a 1% increase in electricity consumption increases CO2 emissions by 0.36%. On the other hand, a 1% increase in GDP per capita increases CO2 emissions by 0.76%, and a 1% increase in energy consumption increases emissions by 2.06%. Thus, all variables show a significant effect. In conclusion, the strategy that Morocco needs to follow to solve our problems is to prioritize investment in research, development and artificial intelligence, while providing adequate training in energy-related fields.

Clarifying the Impact of Electrode Material Heterogeneity on the Thermal Runaway Characteristics of Lithium‐Ion Batteries

The safety and efficiency of lithium‐ion batteries (LIBs) suggest a promising future for this technology, particularly in the automobile industry. However, thermal runaway—wherein a LIB undergoes an uncontrollable increase in temperature that may result in smoke, fire, or explosion—represents an important and widely studied failure type. Since the electrodes of LIBs are manufactured from porous composite materials, their heterogeneity can significantly influence the effective material characteristics and microscale behaviors of LIBs during operation. Microstructure geometric and electrochemical–thermal models are typically used to investigate these impacts. Herein, a microstructure geometric model is constructed of LIB's electrodes. A virtual multiphysics model is used to simulate the overcharging thermal runaway condition. The model's accuracy is validated through real‐world experiments. The model shows greater accuracy compared to the result from a conventional homogeneous geometric model and better reflects the heterogeneous internal phenomenon. The model is applied to a variable analysis in order to investigate how the varying heterogeneity of the cathode's porosity impacts the cell during overcharging thermal runaway behavior. Our results indicate that decreasing porosity heterogeneity at the cathode may delay thermal runaway, owing to the heterogeneous impact on particle diffusion behaviors and the side reaction rate.

The Effects of Olive Oil (Olea Europaea L.) on Cathallase Enzyme Levels in White Rats (Rattus Norvegicus) Wistar Strain of Obese Male

Obesity is a condition of the body resulting from excessive fat accumulation which leads to health problems. The increase in fat metabolism affects increased production of free radicals in the circulation and in adipocyte cells. Free radicals that increase in the body are not in line with antioxidant enzymes, causing a condition called oxidative stress. The body's defense mechanism against free radicals is the synthesis of antioxidants. When there is a decrease in the activity of endogenous antioxidants such as the catalase enzyme, it provides a strong indication of oxidative stress. The presence of polyphenols and monounsaturated fatty acids in olive oil is useful for preventing chronic damage that causes oxidative stress. The catalase enzyme can be used as a parameter for an uncontrolled increase in ROS (Reactive Oxygen Species) or disruption of the function of the antioxidant defense system. To determine changes in levels of the catalase enzyme in an obese male Wistar strain white rat (Rattus norvegicus) animal model that was given olive oil. This research used a true experimental laboratory with a pre- post test design. The results of the study were significant changes in catalase enzyme levels in the olive oil intervention group (p-value 0.003<0.05) on day 14 and day 28 with (p-value 0.002<0.05 and 0.005<0.05). In the group given olive oil, the effect on the level of catalase enzyme was most significant on day 28 (p-value 0.002<0.05).

Immune-related adverse events of antibody-based biological medicines in cancer therapy.

Recombinant antibodies (Abs) are an integral modality for the treatment of multiple tumour malignancies. Since the Food and Drug Administration (FDA) approval of rituximab as the first monoclonal antibody (mAb) for cancer treatment, several mAbs and antibody (Ab)-based therapies have been approved for the treatment of solid tumour malignancies and other cancers. These Abs function by either blocking oncogenic pathways or angiogenesis, modulating immune response, or by delivering a conjugated drug. The use of Ab-based therapy in cancer patients who could benefit from the treatment, however, is still limited by associated toxicity profiles which may stem from biological features and processes related to target binding, alongside biochemical and/or biophysical characteristics of the therapeutic Ab. A significant immune-related adverse event (irAE) associated with Ab-based therapies is cytokine release syndrome (CRS), characterized by the development of fever, rash and even marked, life-threatening hypotension, and acute inflammation with secondary to systemic uncontrolled increase in a range of pro-inflammatory cytokines. Here, we review irAEs associated with specific classes of approved, Ab-based novel cancer immunotherapeutics, namely immune checkpoint (IC)-targeting Abs, bispecific Abs (BsAbs) and Ab-drug-conjugates (ADCs), highlighting the significance of harmonization in preclinical assay development for safety assessment of Ab-based biotherapeutics as an approach to support and refine clinical translation.

THE EFFECT OF DIABETES SELF MANAGEMENT EDUCATION (DSME) ON SELF EFFICACY IN TYPE II DIABETES MELLITUS PATIENTS

Background: Diabetes mellitus (DM) is a health problem in the world. Currently, the number of DM cases globally has reached 537 million people, and Indonesia ranks fifth highest in the world. Low knowledge and dietary compliance are a problem that continues to contribute to new cases and relapses of old cases characterized by uncontrolled increases in blood sugar. This is caused by low self-efficacy which is characterized by feelings of hopelessness. Objectives: The aim of this research was to determine the effect of Diabetes Self-Management Education (DSME) on self-efficacy in type II Diabetes Mellitus patients. Methods: This study used a Quasy-experimental design, with a pretest posttest equivalent control group design, the sample size was 68 type II DM patients, consisting of 34 intervention groups and 34 control groups. Self-efficacy data was collected using the DMSES (Diabetes Management Self Efficacy Scale) questionnaire. Univariate analysis was used to describe the frequency distribution of respondents, mean, median and standard deviation. Next, bivariate analysis used the Wilcoxon test. Results: There was a significant difference in the difference in mean value self-efficacy between before and after intervention with p-value 0.000 < 0.05. Conclusion: Diabetes Management Self Efficacy Scale is effective increase self-efficacy. Thus, DSME can be an alternative intervention to overcome problems and prevent complications in DM patients.

Influence of different Reynolds numbers and new geometries on water jacket cooling performance in a CI engine

Physical damage and emission increases that may occur in the engine due to uncontrolled temperature increases are prevented by cooling systems. In this study, the water jacket (WJ) of the F-Type F8Q706 engine was examined for different Reynolds numbers and geometries. With a combined examination approach, engine tests, 1D engine model, 3D in-cylinder combustion (ICC) model, and 3D WJ CFD studies are presented together, for the first time. Accordingly, a 3D WJ CFD model was developed using in-cylinder parameters calculated from 1D and 3D ICC which were verified by tests. Engine powers in 1D and 3D models, heat transfer, liner temperature, and heat flux in WJ models were compared. The engine powers at 2500 rpm with wide-open throttle are as follows: 1D (33.610 kW), 3D ICC (32.075 kW), engine catalog test (30.890 kW), and a literature test (29 kW). In the WJ model, instead of the Reynolds number 22,128.97, values of 18,440.81–15,367.34–12,806.11–1067.76–8893.14–7410.95–6175.79 were used. In this case, heat transfer decreased by 11.224%–20.844%–29.940%–38.168%–45.723%–52.874%–59.340%. Liner temperature increased by 3.962%–7.505%–10.879%–13.958%–16.800%–19.470%–21.822%. As the Reynolds number decreased, heat transfer decreased, and liner temperature increased. In the WJ, uncontrolled temperature increases were seen in areas farthest from the water inflow. Unlike studies using nanofluids, a new WJ geometry with 169 fins was developed for cooling performance. Nanoparticles cause damage to elastomeric system elements, clogging, and corrosion in lines. This geometry increased heat transfer by 42.01% and reduced liner surface temperatures by 48.28% for 22,128.966 Re. Repeated analyses showed that the fins increased heat transfer.

The Impact of the Arms Race on the Economic Growth of the United States and Russia

The arms race between the United States and the Soviet Union (Russia) during the Cold War had a significant impact on the economic growth of both superpowers. This study examines how the allocation of vast resources for military purposes and threats affected other sectors of the economy. By analyzing historical data on military spending, industrial production, investment, and GDP. The research found that the arms race puts huge pressure on the state budget and creates a trade-off between military spending and investment in productive sectors, which ultimately hampers long-term economic growth in both countries. This study uses secondary data such as journal books, reports from Publish or Perish, Google Scholar, related and relevant websites regarding the arms race and its impact on economic growth through the library research method. The data collection technique used is data triangulation. The purpose of this research is to analyze the impact of the arms race between the US and Russia on the economic growth of both countries. Therefore, it is expected to provide insight and reference for the government in formulating policies regarding the arms race carried out by other countries. The results of this study found the negative impact of the arms race and the importance of placing resources wisely for sustainable economic growth. The impact of the United States and Russia's arms race can hamper long-term economic growth and welfare levels in both countries. Therefore, diplomacy of international cooperation and de-escalation of tensions are necessary to avoid an arms race due to uncontrolled increase in military spending

Modeling MobilityCoins—Charges, Incentives and Multi-period Budgets in Multimodal Transportation Networks

MobilityCoins are a tradable mobility credit (TMC) scheme variant. TMC schemes are a cap-and-trade scheme for managing mobility that are designed to limit negative externalities, e.g., congestion, of traffic. Next to having link-specific or origin–destination-specific charges for cars as in the common TMC scheme, the MobilityCoin scheme’s distinctive elements are accommodating link-specific and origin-and-destination-specific charges and incentives for all modes of transport as well as being considered a mobility currency that can be earned, saved, and spent in multiple time periods. These distinctive features of the MobilityCoin scheme does not alter the core behavioral mechanism of TMC schemes of increasing car travel costs, but these features interfere with the credit market in terms of market volume and market price that ultimately affects traffic outcomes, e.g., an uncontrolled market volume increase can lower the market price that in turns increases the attractiveness of using the car. In this paper, we develop a mathematical model of multimodal macroscopic network flows and a MobilityCoin market to investigate the impacts of charges, incentives, and multi-period budgets. The model is implemented as a single-day model with an integration of sensitivity for multi-period budgets to study how the outcomes in the transportation system change with charges, incentives, and multi-period budgets. Further, we discuss implications for the policy design of MobilityCoins schemes.

Hazards associated with pressure relief devices in hydrogen systems

Hydrogen is increasingly being used as an alternative renewable energy carrier because of its potential to reduce carbon emissions in transportation and heavy industry. Nevertheless, this transition necessitates establishing an infrastructure for storage, transporting, and distributing hydrogen. This infrastructure is typically equipped with pressure relief devices (PRD) to protect systems from uncontrolled pressure increases. Without PRDs, a substantial pressure increase has the potential to rupture equipment and lead to a hydrogen release, which could lead to fires, explosions, and significant damage. However, recent incidents have shown that these PRDs can also be the root cause of leaks and releases. Therefore, there is a need to understand the conditions when PRDs increase the risk versus when these devices effectively mitigate the risk. This paper presents the first comprehensive analysis of past hydrogen incidents involving PRDs and considers when these components succeed and when they fail. We then analyze a diverse, representative subset of events involving PRDs using a root cause analysis (RCA) methodology known as Tripod Beta. Further, we introduce a taxonomy breakdown of the root causes of these incidents. Finally, we provide conclusions related to the observed root causes. The most frequently observed failure modes leading to PRD incidents are 1.) spurious operations of PRDs and 2.) high input to the PRD from components upstream of the PRD, which then activate PRDs. When comparing PRD-mitigated events to PRD-initiated events, we found that PRDs initiated more events than they mitigated; however, it is yet to be seen if this is an artifact of poor (success) data reporting or a true prevalence of PRD activations which undermines their value as a protective feature. The use of Tripod Beta shows that using systematic approaches to incident investigation and analysis provides more causal insight into risk mitigation than simply documenting the occurrence of a single failure. To understand the risk tradeoff that PRD offers, we need more rigorous assessments for the risk & reliability of these components. The results of this study motivate research, design and operational changes, and upcoming codes and standards developments to ensure the continuous, safe, and reliable operation of hydrogen systems.

Detecting diabetic retinopathy using a hybrid ensemble XL machine model with dual weighted-Kernel ELM and improved mayfly optimization

The uncontrolled increase of blood glucose level affects the retina and cause Diabetic Retinopathy (DR), which can permanently damage blood vessels if left untreated for a long time. Early detection helps the patient’s to minimize the severity level. However, the existing Synergic Deep Learning (SDL) model for detecting severity levels of fundus DR images lacks proper filtering methods, suffers from low image quality, and improperly tuned hyperparameters. To address these issues, a hybrid ensemble Extreme Learning (XL) machine model is proposed in detection and classification of DR. The proposed model includes preprocessing steps, such as image filtering, conversion, segmentation, and morphological operations, to improve image quality. Also the parameters are tuned effectively and the weight functions are analyzed based on the extracted features that lower the blurriness of the images. A Dual Weighted-Kernel Extreme Learning Machine (DW-KELM) is developed to classify DR images with improved accuracy, and an Improved Mayfly Optimization (IMO) algorithm is applied to optimize the DW-KELM model’s parameters. Implementing the Weighted Average Ensemble (WAE) technique enhances the model’s performance by allocating different weights. Two datasets, namely the SUSTech-SYSU, APTOS-2019 and IDRID datasets, are used for experimentation, and the results revealed that DW-KELM achieved 99% accuracy, with an overall sensitivity, specificity, precision, and F1-score of 98.52%, 96.32%, 98.10%, and 98.52% respectively. The proposed model achieved better performance in classifying 5 DR classes, including moderate DR, Proliferative DR, no DR, severe DR, and mild DR, with good image quality.

Implementation and evaluation of the WHO maternity care model: a convergent parallel mixed-methods study protocol.

According to the World Health Organization (WHO), intrapartum care is considered a platform for providing respectful, personalized, and women-centered services to women. This study aims to investigate the intrapartum care model proposed by WHO. This convergent parallel mixed-methods study will be carried out in qualitative and quantitative phases. In the quantitative phase (a quasi-experimental study), 108 pregnant women admitted to the maternity ward will be randomized to intervention (receiving intrapartum care based on the WHO model) and control group (receiving routine hospital care) before the beginning of the active stage of labor (cervix dilatation equal to 5 cm) and Wijma's delivery fear scale (DFS) will be completed for them and again at 7-8 cm dilatation. The participants of both groups will be followed up for 6 weeks after labor and then they will be invited to a relatively quiet place to complete the Childbirth Experience Questionnaire (CEQ 2.0), the Edinburgh Postpartum Depression Scale (EPDS), the Post-Traumatic Stress Disorder (PTSD) Symptom Scale (PSS-I), the Pregnancy and Childbirth Questionnaire (PCQ), exclusive breastfeeding and a checklist on willingness to give birth to another child. The qualitative phase will employ content analysis to explain mothers' views about the effects of this model especially subjective components of this model on their labor process after 4-6 weeks. The two phase's results will be discussed in combination. The implementation of such care models is expected to prevent mental disorders caused by negative experiences of childbirth, and also, prevent uncontrolled increases in cesarean sections. https://fa.irct.ir/user/trial/68313/view, identifier (IRCT20120718010324N69).

- Invited Review - Pig meat production in the European Union-27: current status, challenges, and future trends.

The main objective of this study was to present data on the current situation and future trends of pig meat production in the European Union-27 (EU). Pig production has played an important social and economic role for centuries in many states of the EU. In 2022, pig meat production in the EU reached 23 M tons, which represented 21% of total production worldwide. The two key reasons that justify such amount of pork produced, are the acceptance and high consumption of the meat by the local population and the high quality of the meat produced which facilitated pork export. However, current data show a reduction in pork production for the last three years, as a consequence of a series of events that include i) problems with the chain of ingredients supply, ii) uncontrolled increase in African Swine Fever (ASF) outbreaks, iii) fast recovery of pig production in China, iv) increasing concerns by the rural population on the high cost to meet future requirements of the EU legislation on farm management, environmental sustainability and animal welfare, v) increased cost of all inputs involved in pig production and vi) limited interest of the new farmer generation to work on the pig sector. Consequently, pork production is expected to decrease in the EU for the next years, although sales will be maintained at a relative high level because pork is the meat preferred by local consumers in most EU countries. In order to maintain the favourable position of the pork industry in the near future, strategies to implement include: i) maintain the quality of the meat destinated to export markets, ii) improve the control of outbreaks of ASF and other swine diseases, iii) implementation of technological innovations to improve working conditions making more attractive to work in the pork sector of the food chain to the new generation of farmers and workers.

Oxidative Stress Induced by Cortisol in Human Platelets.

Hypercortisolism is known to affect platelet function. However, few studies have approached the effect of exogenous cortisol on human platelets, and the results obtained are conflicting and unconvincing. In this study, the effect of exogenous cortisol on several parameters indicative of oxidative status in human platelets has been analysed. We have found that cortisol stimulates ROS production, superoxide anion formation, and lipid peroxidation, with these parameters being in strict correlation. In addition, cortisol decreases GSH and membrane SH-group content, evidencing that the hormone potentiates oxidative stress, depleting platelet antioxidant defence. The involvement of src, syk, PI3K, and AKT enzymes in oxidative mechanisms induced by cortisol is shown. The main sources of ROS in cells can include uncontrolled increase of NADPH oxidase activity and uncoupled aerobic respiration during oxidative phosphorylation. Both mechanisms seem to be involved in ROS formation induced by cortisol, as the NADPH oxidase 1 inhibitor 2(trifluoromethyl)phenothiazine, and rotenone and antimycin A, complex I and III inhibitor, respectively, significantly reduce oxidative stress. On the contrary, the NADPH oxidase inhibitor gp91ds-tat, malate and NaCN, complex II and IV inhibitor, respectively, have a minor effect. It is likely that, in human platelets, oxidative stress induced by cortisol can be associated with venous and arterial thrombosis, greatly contributing to cardiovascular diseases.

Termination of Citizenship of the Russian Federation because of Crimes or Actions that Pose a Threat to National Security: A Comparative Legal Aspect

The formation of a new direction of state policy on the termination of citizenship of the Russian Federation is conditioned by the need to ensure the national security of the country in the modern world. The international legal doctrine in the field of revocation of citizenship states that this measure will never be able to comply with modern international human rights law, while many Western states turn to this institution not only when perpetrators commit terrorist crimes, but also in all types of treason. The objectives of the study are a comparative legal and historical analysis of the regulations on the termination of citizenship for crimes and actions that infringe on national security in Russia and a number of countries in which this practice exists. The purpose of the study is to analyze trends in the formation of Russian state policy in this area. The methodological basis of the research is the use of general scientific and private scientific methods of cognition, including historical and formal legal ones. The authors conclude that the termination of citizenship is a de facto sanction. Punishment in the form of revocation of citizenship can be a deterrent in conditions of constant (often uncontrolled) increase in the Russian population due to migrants. Termination of citizenship as an additional criminal law measure to the main type of punishment should be applied only by the court, accordingly, such a sanction should be fixed directly in the criminal law. The authors point to the need to modernize the legislation on citizenship of the Russian Federation, as well as to expand the list of types of penalties provided for by criminal law, provisions on termination of citizenship for committing specific crimes and actions that pose a threat to national security.

Experimental research on vehicles equipped with a GMP Hybrid for the new Euro 7 emissions standard

With the increase the number of vehicles on European roads, the road transport has become the biggest source of air pollution in the cities of the old continent. According to European Commission estimates in 2018, more than 39% of NOx (nitrogen oxides) emissions and 10% of PM2.5 and PM10 emissions (mechanical particles with diameters of 2.5 and 10 micrometers) were attributed to road transport. It is known that, in order to limit to some extent, the uncontrolled increase in harmful emissions from road vehicles, the European Commission has gradually introduced new pollution standards to be met by manufacturers of new vehicles. In the second half of 2022, the Commission presented a new proposal to reduce pollutant emissions from new vehicles sold in the European Union (EU), defining the new Euro 7 pollution standards. Compared to Euro 6 by 2035, according to European Commission estimates, these new Euro 7 standards, together with a progressive increase in the number of electric vehicles sold, aim to reduce pollutant emissions from private vehicles and vans by around 35% for NOx emissions and around 13% for particulate emissions. Therefore, both the Euro 7 and CO2 emissions standard (CAFE) for vehicles have been designed to improve air quality in cities and reduce greenhouse gas emissions, including by increasing the use of electric vehicles. Starting from this hypothesis, the first part of the paper presents the experimental model developed in the AMESim simulation platform of a mid-size vehicle equipped with a hybrid GMP, tested on a roller bench, which simulates pollutant emissions in this new Euro 7 standard. In the second part of the paper, the simulation results and possible causes influencing hybrid GMP behavior leading to the evolution of pollutant emissions are analyzed. Finally, the paper formulates conclusions on the evolution of pollutant emissions.

Pharmacy Schools Council warns of academic staff shortage amid ‘uncontrolled increase’ in MPharm courses

Pharmacy Schools Council warns of academic staff shortage amid ‘uncontrolled increase’ in MPharm courses
