Противодействие распространению антиправительственных изданий на железных дорогах России в последней четверти XIX – начале XX в. По материалам жандармской железнодорожной полиции

The article is devoted to the reconstruction of the historical experience of countering the spread of revolutionary and anti-war literature within the steel highways of the Russian Empire in the last quarter of the 19th – early 20th centuries. Based on an analysis of the records of the gendarmerie railway police, two main directions of the gendarmes’ struggle with anti-government publications were identified - supervisory activities and obtaining information from secret informants. The importance of countering the spread of illegal publications on railways was determined by the concentration of passengers within their infrastructure. This struggle took on particular significance during the First World War, when the activity of agitators was aimed at instilling pacifist sentiments among the lower ranks and officers. Through the press, revolutionaries criticized the tsarist government and the decisions it made; discredited the imperial family and the ruling dynasties of countries allied with Russia. The Police Department of the Ministry of Internal Affairs notified the railway gendarmerie police departments (GPUZD) about the admission of representatives of public organizations and publishing houses to railway stations. The legality of the activities of literature distributors was checked by gendarmerie officials. Often, agitators resorted to subterfuge, handing over revolutionary literature under covers that did not arouse suspicion. The supervision of the gendarmerie railway police also covered events held at mobile exhibition carriages and lecture carriages. The books and brochures given to their visitors were studied. The largest number of prohibited publications was identified during inspections of library bookcases located at railway stations. To discover hidden copies, it was allowed to send informants to librarians with a request to provide prohibited literature for reading. The provision of such a service by a librarian became the basis for a careful inspection of the institution entrusted to him. The interaction of railway gendarmes with informants was not limited to the supervision of libraries. Information was received from agents among the revolutionaries about cargoes of illegal literature transported by rail. The names of such cargo in the accompanying documentation were distorted by the senders. Cases of railway employees assisting in the transportation of revolutionary literature on trains were revealed. It was concluded that the gendarmerie implemented a wide range of measures aimed at suppressing the spread of harmful literature within the railway infrastructure entrusted to them. At the same time, the depth of the socio-political crisis in Russia, which ended with the destruction of the empire in 1917, did not allow the gendarmes to radically influence the spread of revolutionary agitation.

A MULTI-PERSPECTIVE VIEW ON THE CONCEPT OF SOCIAL PROTECTION AND THE ROLE OF SOCIAL WORK IN (NOT ONLY) WARTIME CONDITIONS

The purpose of this article is to explore the multifaceted dimensions of the concept of social protection and the role of social work in (not only) wartime conditions. This is necessary, because social workers are often acting “helpless” confronted with massive global crises or even wars or war-like conditions. This article tries to sharpen the possible role and position of social work and with this the expectations on the discipline and profession of social work. To reach this, this article wants to shed light on the subject and the understanding of “crisis” and the different perspectives surrounding the interdisciplinary and multi perspective concepts of social protection, social support, and resilience. This perspective allows to a better understanding of the underlying principles, challenges and potential solutions related to social protection in times of crisis. In times of crisis, ensuring social protection and social support becomes an urgent priority for affected populations and even individuals. Social protection encompasses a wide range of measures designed to protect individuals and communities from the adverse effects of crises and to provide them with the necessary resources and assistance to cope with the challenges they face. This article is on the one side a s theoretical examination of the key terms. On the other hand directly affected people have their say: The co-author as a Ukrainian narrates her migration experiences and the results of a student - peer project with affected refugees from Ukraine in Eastern Switzerland are presented. The results are concrete and surprise at some points and sharpen the task and role of social work: First, feeling safe and getting (social) support and psychological assistance in the trauma and war situation is much important even to feel welcome and resurrected. But then mobility, networks, and the change to support their families, relatives and friends at home have a great importance. It is also very important to be able to travel to Ukraine (home) from time to time and to be able to return to the host country. The task of social work is a very special one: It is not primarily the role of the benefactor and care giver, but of the professional who makes things possible and supports and empowers the people who feel it. The article also makes clear, that a one-dimensional and static understanding of crisis, flight, migration and needs no longer works in today's world global situations and crisis. Keywords: Social work, social protection, social support, crises, war in Ukraine, Ukrainian refugees, needs

ECO-INDUSTRIAL PARKS AS A DIRECTION OF INNOVATIVE DEVELOPMENT OF PRODUCTION TERRITORIES

The article discusses the problems and tasks of the environmental direction in the development of modern industrial production in the context of post-war recovery and development of the Ukrainian economy. The success of such a task will depend on the extent to which industrial policy and development strategies at the state and local levels are oriented towards modern global trends - innovative digital and production technologies and environmental standards. At the present stage, the concept of building and developing a network of eco-industrial parks is such a solution.
 Based on the analysis of the world experience in the formation and functioning of eco-industrial parks, the article presents a wide range and various combinations of environmental protection measures and approaches to managing environmental and resource problems in the structure of eco-industrial parks. The main directions of eco-innovations are highlighted: from "clean production" and "green energy" to urban-industrial symbiosis.
 The authors substantiates the relevance of ecological transformation of the domestic industrial sector at the present stage. It is important that innovative sustainable industrial development takes place as a reciprocal process, by balancing the issues of economy, ecology, society and urban planning, where all stakeholders - public and private structures - jointly develop measures for planning, designing and building a network of eco-industrial parks in the country.

“We literally worked in parking lots, cars, garages, and separately set up party tents”: qualitative study on the experiences of GPs in the frame of the SARS-CoV-2 pandemic in Austria

BackgroundPrimary care is internationally recognised as one of the cornerstones of health care. During the COVID-19 pandemic, primary care physicians were assigned a variety of tasks and thus made a significant contribution to a country’s pandemic response. They were expected to perform a variety of tasks, such as diagnosing and treating people with COVID-19, maintaining health care for all other patients, as well as several public health tasks, such as diagnostic testing and vaccination, protecting patients and staff from infection, and serving as community trusted persons. In Austria, there are no structured levels of care, no definition of the role of the general practitioner during a pandemic is given, and no specific support structures are present. The aim of this study was to assess the views and experiences of primary care physicians regarding supportive and hindering factors for pandemic preparedness in Austria.MethodsQualitative study using semi-structured interviews. A total of 30 general practitioners were interviewed, with particular attention to an equitable distribution in small, medium and large primary care facilities. Qualitative content analysis was performed.ResultsInterviewees described a wide range of infection control, organisational and communication measures that they had implemented. They made changes to practise equipment, found makeshift solutions when supplies were scarce, and established communication and information pathways when official communication lines were inadequate.ConclusionGeneral practitioners took on essential tasks and showed a high level of understanding of their role in the pandemic response. This was achieved mainly at an informal level and with high personal commitment. Their functioning in the absence of structural regulations and support shows that they had a clear intrinsic understanding of their responsibilities. To ensure reliability and sustainability and to reduce their burden, it will be necessary to clarify the role and tasks of a general practitioner and to provide the necessary support. This concerns both infrastructural support and communication and information strategies. As part of the reform to strengthen primary care, primary care needs to be seen, valued and involved in decision-making processes.

High-entropy (Co0.2Mn0.2Fe0.2Zn0.2Al0.2)3O4 thick-film NTC thermistor with high aging stability and wide temperature measurement range

Here, a novel type of high-entropy (Co0.2Mn0.2Fe0.2Zn0.2Al0.2)3O4 solid-solution ceramics with spinel phase structure was designed and successfully fabricated based on an entropy engineering approach. Additionally, the impact of sintering temperature, a critical factor in entropy stabilization, on structural and electrical behavior was systematically examined at a range of 1110∼1150 °C. The results indicate that each synthesized sample exhibits a single spinel structure in the Fd‾3 m (227) space group, and all five metal elements were uniformly distributed, demonstrating entropy stabilization. Meanwhile, the fabricated high-entropy ceramics manifest exceptional negative temperature coefficient (NTC) characteristics in the temperature range of 25 °C–350 °C. The aging stability is excellent as well. After aging at 150 °C for 1000 h, the ΔR/R0 of thick-film samples sintered at 1150 °C is less than 1 %. The successful synthesis of this novel class of spinel-type high-entropy ceramics introduces an emerging design approach for the development of NTC thermistors, particularly for applications in medium-temperature environments.

Understanding Hybrid Threats and their Societal Impact – Republic of Moldova Case Study

Abstract Hybrid threats undermine societies and foster unrest. Russia’s brutal and unjustified war against Ukraine has changed Moldova’s geopolitical situation. As President Maia Sandu states “using the full range of hybrid threats - including false bomb threats, cyber-attacks, disinformation, calls for social unrest and open corruption – Russia has sought to destabilize the government, erode our democracy and jeopardize Moldova’s contribution to the security of Europe as a whole”. Through consultants, money transfers, and fostering corruption, Russia is interfering in Moldova’s political landscape. However, the international community is highly concerned and supports the Republic of Moldova through a wide range of measures and instruments. The goal of this article is to highlight the main hybrid actions, their impact on Moldovan society, and the state authority’s response in responding to these hybrid threats. Consequently, this article emphasizes the difficulty of ensuring political sustainability amid an intense hybrid warfare.

Understanding Society: health, biomarker and genetic data

AbstractUnderstanding Society, the UK Household Longitudinal Study includes a wide range of health measures, and in particular biomarker and genetic data. This makes it a unique resource for research on the economics of health. We review the main features of the biomarker data, how they are collected, and evidence on data quality. We also discuss examples of how these data have been used in economic research to date.

Development of a high-voltage radio frequency power supply for quadrupole mass spectrometers with a wide dynamic measurement range

The core component of a quadrupole mass spectrometer is the quadrupole mass filter, serving a crucial role in ion analysis. It operates by applying two sets of high-voltage, high-frequency signals with equal amplitude and opposing phases through the radio frequency power supply, capitalizing on variations in the electric field and differences in mass-to-charge ratios to separate incoming ions. This study leverages direct digital frequency synthesis technology and multi-stage voltage amplification techniques to design a tailored radio frequency power supply for quadrupole mass spectrometers with a broad mass range. Practical testing demonstrates that this power supply generates radio frequency high-voltage signals with a peak-to-peak voltage ranging from 2.210 V to 4.220 kV at a resonant frequency of 1.240 MHz, facilitating the separation of ions with distinct m/z values. Furthermore, the radio frequency power supply is integrated into a Self-developed quadrupole mass spectrometer, enabling an assessment of the mass range, resolution, stability of the spectrometer. The results of these assessments confirm that the developed power supply accommodates scanning of m/z value ions in the range of 1 to 1067 while maintaining an absolute resolution of less than m/z = 1 units and an instrument stability of 2.00% over four hours.and keywords.

High-resolution photonic-assisted microwave frequency identification based on an ultrahigh-Q hybrid optical filter

Photonic-assisted microwave frequency identification has been extensively studied in civil and defense applications due to its distinct features including wide frequency coverage, large instantaneous bandwidth, high frequency resolution, and immunity to electromagnetic interference. In this paper, we propose and experimentally demonstrate an approach for high-resolution frequency identification of wideband microwave signals by linearly mapping the microwave frequencies to the time delays of the optical pulses. In the proposed system, an ultrahigh-Q hybrid optical filter is a key component, which consists of a fiber ring resonator (FRR) and a silicon photonic racetrack micro-ring resonator (MRR). The FRR has an ultra-narrow bandwidth of 7.6 MHz and a small free spectral range (FSR) of 292.5 MHz, while the MRR has a bandwidth of 167.5 MHz and a large FSR of 73.8 GHz. By precisely matching the resonance wavelengths of the FRR and the MRR, a hybrid optical filter with an ultrahigh Q-factor and a large FSR is realized, which is much preferred to realizing a high resolution and a wide measurement range for microwave frequency identification. An experiment is performed and different types of microwave signals are identified. A frequency measurement range as broad as 33 GHz from 2 to 35 GHz, a frequency resolution as high as 15 MHz and a measurement accuracy as high as 5.6 MHz are experimentally demonstrated. The proposed frequency identification system holds great advantages including high frequency resolution, high measurement accuracy, and wide frequency coverage, which can find extensive applications in next-generation electronic warfare and cognitive radio systems.

First operation of the JUNGFRAU detector in 16-memory cell mode at European XFEL

The JUNGFRAU detector is a well-established hybrid pixel detector developed at the Paul Scherrer Institut (PSI) designed for free-electron laser (FEL) applications. JUNGFRAU features a charge-integrating dynamic gain switching architecture, with three different gain stages and 75 μm pixel pitch. It is widely used at the European X-ray Free-Electron Laser (EuXFEL), a facility which produces high brilliance X-ray pulses at MHz repetition rate in the form of bursts repeating at 10 Hz. In nominal configuration, the detector utilizes only a single memory cell and supports data acquisition up to 2 kHz. This constrains the operation of the detector to a 10 Hz frame rate when combined with the pulsed train structure of the EuXFEL. When configured in so-called burst mode, the JUNGFRAU detector can acquire a series of images into sixteen memory cells at a maximum rate of around 150 kHz. This acquisition scheme is better suited for the time structure of the X-rays as well as the pump laser pulses at the EuXFEL. To ensure confidence in the use of the burst mode at EuXFEL, a wide range of measurements have been performed to characterize the detector, especially to validate the detector alibration procedures. In particular, by analyzing the detector response to varying photon intensity (so called ‘intensity scan’), special attention was given to the characterization of the transitions between gain stages. The detector was operated in both dynamic gain switching and fixed gain modes. Results of these measurements indicate difficulties in the characterization of the detector dynamic gain switching response while operated in burst mode, while no major issues have been found with fixed gain operation. Based on this outcome, fixed gain operation mode with all the memory cells was used during two experiments at EuXFEL, namely in serial femtosecond protein crystallography and Kossel lines measurements. The positive outcome of these two experiments validates the good results previously obtained, and opens the possibility for a wider usage of the detector in burst operation mode, although compromises are needed on the dynamic range.

The Influence of Nucleoside Reverse Transcriptase Inhibitors on Mitochondrial Activity, Lipid Content, and Fatty-Acid-Binding Protein Levels in Microglial HMC3 Cells.

Despite the availability of a wide range of preventive measures and comprehensive treatment options following infection, the development of acquired immunodeficiency syndrome (AIDS) remains a persistent challenge. Nucleoside reverse transcriptase inhibitors (NRTIs) represent the most commonly utilized therapeutic approach, despite being on the pharmaceutical market for nearly four decades. During this time, a spectrum of side effects ranging from mild discomfort and hypersensitivity reactions to the more prevalent nephrotoxicity and hepatotoxicity has been documented. In light of these considerations, our study aimed to investigate the impacts of two NRTIs, lamivudine and zidovudine, on lipid metabolism in HMC3 microglial cells. Our findings revealed statistically significant reductions in the ATP levels (nearly 8%) and increased mitochondrial superoxide levels (around 10%) after 24 h of treatment with the maximum therapeutic concentration of zidovudine compared to the untreated microglial cells. Furthermore, the concentrations of fatty-acid-binding proteins 4 and 5 were significantly lower (approximately 40%) in the microglial cells that were exposed to NRTIs than in the untreated cells. Notably, the total lipid concentration within the microglial cells markedly increased following NRTI administration with a 13% rise after treatment with 10 µM lamivudine and a remarkable 70% surge following the administration of 6 µM zidovudine. These results suggest that the prolonged administration of NRTIs may potentially lead to lipid accumulation, posing a significant risk to the delicate homeostasis of the neuronal system and potentially triggering a pro-inflammatory response in microglial cells.

Development and characterization of a highly sensitive magnetic electronic skin for intelligent manipulators

A magnetic electronic skin (e-skin) with high sensitivity, flexibility, and wide force measurement range was designed. The e-skin includes a top magnetic film layer, a middle polydimethylsiloxane (PDMS) layer and a bottom tunneling magnetoresistive sensor layer. The magnetic film layer is composed of neodymium-iron-boron particles (Nd2Fe14B) and PDMS. A test platform was established. The test results showed that the e-skin could measure forces in the range of 0.05–20 N, with a static sensitivity of 287 mV/N within 0–1 N, followed by a gradual decrease in sensitivity with an increase in static force. The resolution of the electronic skin was 0.05 N, and the change in sensitivity under dynamic force was less than 3.17 %. The response time and recovery time were 41 ms and 40 ms, respectively. This study provides a foundation for further research and development of advanced electronic skins for use in a variety of flexible electronic applications.

Liquid crystal-embedded fiber optic fabry perot temperature sensor based on Vernier effect

An optical temperature sensing method with ultra-high sensitivity and a wide measurement range is proposed. The performance enhancements come from the high thermos-optical coefficient of liquid crystal (LC) material, and the Vernier effect produced by LC birefringence characteristics. This paper proposes and demonstrates a method to enhance the measurement range of the LC temperature sensor. A miniature LC temperature sensor was made by using an optical fiber Fabry-Perot interferometer (FPI). To compensate for and attenuation of LC and improve the contrast of the FPI, silver films are coated on one end of the optical fiber. Due to the high birefringence of the LC in the interferometer, a Vernier spectrum can be observed in the reflection. The temperature measurement range of 20–32 °C and the temperature sensitivity of the Vernier peaks of a sensor sample is about 42.18 nm/°C, which is much higher than the sensitivity of the cascaded FBG in structure. The limited measurement range is due to the free spectral range (FSR) limitation. In this context, the FBG peak can be used as a temperature reference while switching the adjacent Vernier peaks. Hence, this LC temperature sensor exhibits high sensitivity as well as a wide measuring range, which would broaden the application scope of the LC temperature sensors.

High sensitivity refractive index sensor based on double peanut-shaped and etched multimode fiber structures

A fiber optic refractive index (RI) sensor based on an etched multimode fiber (MMF) with a double peanut-shaped structure is proposed and experimentally demonstrated. The sensor consists of two peanut-shaped and a section of etched MMF tapered fiber structure. The excitation of the fundamental mode to higher-order modes is facilitated by using the beam splitting/coupling effect of the double peanut-shaped and etched taper structures, and the higher-order modes can be excited into an evanescent field. In the sensing medium, the stronger the evanescent field, the stronger the energy shock between the fiber and the sensing environment. Experimental results showed that the sensitivity was 326.52 nm/RUI and 823.91 nm/RUI when the etched waist taper diameter was 51.92 μm and the glycerol solution index ranged from 1.3395 to 1.3945 and 1.3945 to 1.4200, respectively. Compared to the MMF sensor structure without etching, the RI sensitivity is improved by about 2 times. In addition, the temperature characteristics of the sensor were investigated over a range of 30 °C–100 °C, and the results showed a maximum temperature sensitivity of only 30.24 pm °m−1. The sensor structure has a low-temperature sensitivity and the temperature effect on the RI measurement results is negligible within the allowable error range. The sensor has the advantages of simple fabrication, wide measurement range, good stability, low cost, and compact structure, which has potential application value in the field of RI detection.

Improving the practicality of recombinant Escherichia coli biosensor in detecting trace Cr(VI) by modifying the cryogenic storage conditions of biosensors and applying simple pretreatment

Hexavalent chromium (Cr(VI)) is a global environmental pollutant. To reduce the risk caused by Cr(VI), a simple, accurate, reproducible, and inexpensive method for quantifying Cr(VI) in water and soil should be developed. In this study, three types of recombinant Escherichia coli biosensors (namely T7-lux-E. coli, T3-lux-E. coli, and SP6-lux-E. coli biosensor) containing promoters (T7, T3, and SP6), chromate-sensing regulator chrB, and the reporter gene luxAB were constructed. This study investigated the effects of cryogenic freezing temperature and time on trace Cr(VI) measurement by using recombinant E. coli biosensors. The results indicated that the activity of thawed frozen SP6-lux-E. coli cells stored at −20 °C for 270 days did not differ from that of freshly prepared cells. Turbidity and conductivity in water samples and organic matter in soil interfered with Cr(VI) measurement using the biosensor. The SP6-lux-E. coli biosensor exhibited a wide measurement range and a low deviation of <5% for measuring Cr(VI) in various Cr(VI)-contaminated water and soil samples and required only a simple pretreatment or extraction process even after 270-day storage at −20 °C. To the best of our knowledge, this is the first study to report the use of recombinant biosensors for accurately measuring Cr(VI) in both water and soil.

Motion estimation from noisy data with unknown distributions using multi-frame phase-preserving denoising

Phase-based motion estimation method is promising due to its high resolution and wide measurement range. Generally, noise exists in digital images and ruins the constant phase assumption of the same target among different frames. However, traditional image-denoising techniques do not consider the phase and result in inaccurate motion estimation. A novel phase-preserving denoising method considering multiple frames is proposed. In this approach, multi-scale and multi-orientation quadrature filters transform noisy images into complex pyramids to preserve the phase of the content. An instability indicator is designed to evaluate the relative noise intensity at each level of the complex pyramid among multiple frames. The threshold is then estimated to retain the phase of interest and reconstruct a denoised image with unknown noise distributions. Numerical and experimental examples demonstrate that the proposed method effectively preserves the phase of interest and decreases the error of the estimated motion, outperforming other typical denoising methods under various types of noise.

Role of community pharmacy and pharmacists in self care in Sweden

BackgroundSelf care is an important concept, which is increasingly being applied by policy makers on a large scale. It is associated with improved health literacy and technological advances. Community pharmacy practitioners are easily accessible for self care counselling, purchase of non-prescription products and for referrals to other healthcare providers. ObjectiveTo describe self care policies and strategies in Swedish healthcare authorities, pharmaceutical organizations and community pharmacy. MethodsA search was conducted to retrieve self care policy documents and strategies in Swedish healthcare authorities, pharmaceutical organizations and community pharmacy on respective websites, as well as personal contacts with key persons in pharmaceutical organizations and community pharmacy practice. ResultsA new law on self care was adopted by the Swedish Parliament becoming effective in 2023. The law defines self care as a healthcare measure that has been assessed by a treating licenced healthcare practitioner to be possible to be performed by the patient him/herself. The law includes a wide range of measures. According to a Government Commission that followed Sweden's the National Pharmaceutical Strategy's Action Plan in 2018, the Medical Products Agency (MPA) was assigned to establish requirements of qualifications in self care counselling. In its report in late 2022, the MPA stated that self care counselling by community pharmacy practitioners plays an important role in society. The new requirements are expected to become effective in mid-2023. None of the four community pharmacy chains operating 97% of Sweden's community pharmacies have developed any specific self care policies, although self care counselling and sales of non-prescription products, as well as provision of some primary healthcare services, constitute important components of their operations. Furthermore, all Swedish pharmacies offer several digital self care solutions, supporting people to manage their own health. Neither the Swedish Pharmacy Association, representing most pharmacies, nor the Swedish Pharmacists Association, the trade union, have developed any self care policies. However, the Swedish Association of the Pharmaceutical Industry is promulgating Swedish self care reform using a systematic review of self care and which medicines should be over-the-counter. ConclusionsSelf care is not currently established as a core pillar of a Swedish national health strategy. There are further opportunities to enable pharmacists to fulfil their potential in supporting individual wellbeing and promoting self care interventions. A new system needs to be created which fully integrates the promotion of everyday wellbeing, self care for self-treatable conditions and the management of long-term conditions.

The Lithuania-China Row: The European Union’s Search for a Strategy and Instruments to Deal With China

The increasing use of measures of economic coercion by China has caused its trading partners to review their close trade ties with that country as well as their ability to resist such pressure. In December 2022, the European Union (EU) requested that the World Trade Organization (WTO) adjudicate its dispute with China regarding restrictive trade measures China had imposed on Lithuania in response to its foreign policy actions that were not to China’s liking. The EU also drafted new legislation – the Regulation of the European Parliament and of the Council on the Protection of the Union and its Member States from Economic Coercion by Third Countries – to deter third countries from applying coercive measures that target the EU and its Member States. This paper considers the new instrument in the context of the EU’s evolving ‘economic de-risking’ strategy on China and a wide range of measures aimed at protecting the common market from the unfair behaviour of China and other states and reducing the EU vulnerability vis-à-vis economic and security threats. The EU’s ability to deter states from applying coercive measures against it hinges upon its ability to strengthen its market power and to use the new instrument when necessary. economic coercion, countermeasures, EU Anti-coercion Instrument, China, World Trade Organization, European Union, economic ‘de-risking’ strategy, regulatory sovereignty, selfreliance, international law
