Authors: Barcik Jacek , Kost Gabriel , Hetmanczyk Mariusz
Published: March 2024

The article discusses development work on the control system of an electric vehicle considering the limitations of the TM4 Sumo power unit. Particular attention was focused on the development of a new algorithm for controlling the final phase of braking (using a retarder) at low speeds, using proprietary regulators based on the prediction of braking force values. The developed algorithm is universal (works with various drive units) automatically adjusting the setting values. At the same time, the authors paid particular attention to the elimination of the phenomenon of oscillation of the engine torque value in the final phase of braking and the synergy of the classic braking system of a commercial vehicle with electric drive braking. The article also discusses proprietary tools and software for monitoring and collecting measurement data from electric vehicles. The control algorithm is one of the products offered on the market as a solution provided by the DIGA Civil Partnership. The presented results were collected from real objects as part of implementations carried out by the authors.
Evolutionary process of changing marine fuels - transition fuels on the way to the hydrogen era
Authors: Herdzik Jerzy
Published: March 2024

The article presents the ongoing transformation of marine fuels - from fossil fuels to transition fuels and the final target - hydrogen. This process was forced by the legal regulations of the International Maritime Organization and the European Union Parliament. The target year is 2050, but intermediate targets should be achieved in 2030 and 2040. The base year is 2008. By the end of 2022, an increasing trend of interest in more environmentally friendly fuels was observed. However, it is far from expectations. Analyzing ships under construction and those ordered, a much higher share of renewable fuels intended for propulsion of ships is observed. The shipowners took precautionary measures. They order ships for transitional fuels, which reduce investment and operating costs, assuming that far-reaching changes will take place after overcoming significant technological problems, lowering the prices of equipment and fuel. The article analyzes the ongoing processes, justifying the sense of the actions taken. The regulations being introduced have a significant impact on the ongoing transformation processes of marine fuels. It was noted that they may have serious consequences for maritime transport, indicating potential threats.
Selezen А.О., Piskach L.V. INTERACTION IN THE QUASI-TERNARY Tl2Se–CdSe–SnSe2 SYSTEM
Authors: Selezen A.O. , Piskach L.V.
Published: March 2024

The nature of physicochemical interaction in the Tl2Se–CdSe–SnSe2 system was investigated by X-ray diffraction, DTA and microstructure methods. The system at 570 K contains α-, β-, γ-,  δ-, ε-, h-, σ-solid solution ranges of Tl2Se, CdSe, SnSe2, Tl4SnSe4, Tl2SnSe3, Tl2Sn2Se5  and a low-temperature modification of the quaternary compound Tl2CdSnSe4 that crystallizes in the tetragonal SG I-42m. The liquidus surface projection of this system includes the fields of the primary crystallization of all solid solutions, and h¢-solid solution ranges of HT-modification of Tl2CdSnSe4. These fields are separated by 21 monovariant curves and 19 nonvariant points. Six nonvariant processes occur in this system: three peritectic LU1+β↔d+σ, LU2+β↔σ¢+γ, LU3+γ↔ σ¢+h  and three eutectic LE1↔α+β+d, LE2↔δ+ε+σ, LE3↔ε+h+σ and the processes associated with the phase transition of the quaternary phase σ↔σ¢. Two quasi-binary sections Tl4SnSe4–CdSe and Tl2SnSe3–CdSe triangulate the quasi-ternary Tl2Se–CdSe–SnSe2 system into three subsystems, Tl2Se–CdSe–Tl4SnSe4, Tl4SnSe4–CdSe–Tl2SnSe3, and Tl2SnSe3–CdSe–SnSe2, for which spatial state diagrams were plotted. The eutectic process E1 takes place in the first subsystem at 592 K; the second subsystem features peritectic process U1 at 680 K and eutectic process E2 at 665 K. Two peritectic processes U2 at 775 K and U3 at 696 K and the eutectic process E3 at 643 K take place in the third subsystem; the plane at 623 K is associated with the solid-phase decomposition of the Tl2Sn2Se5 compound by reaction h↔ε+γ.

Keywords: phase equilibria; polythermal sections; liquidus surface; spatial state diagrams.

Published: March 2024

Fluorine, as a essential trace element, plays an important role in maintaining human health, but an excess of fluorides causes various diseases. The main way fluoride enters the human is drinking water, the source of which is natural surface and underground water. In surface and groundwater, fluorides can exist in bound (compounds with aluminum, iron, calcium and magnesium) and free (bioavailable) forms, therefore, when monitoring natural waters, it is important to distinguish between the total content of fluorides and the content of bioavailable forms. This work presents a screening of the content of bioavailable forms of fluorides in surface (river) and underground (well) waters of the Tisza River basin. The study was carried out in the summer (June-August) period of 2023. The screening results showed that river waters have a lower concentration of bioavailable forms of fluorides (2.9-8.3 μg×L-1) than groundwater (7.5-14.4 μg×L-1). It was established that the content of bioavailable forms of fluorides in natural waters is determined, first of all, by the geology of the territories (the lowest content in mountainous areas, and the highest in lowland areas), and for surface waters also by the morphologys of the river. For river waters, the general pattern of fluoride content distribution is complicated and ambiguous. In general, the content of bioavailable forms of fluorides in the surface and underground waters of the Tisza River basin is small, which causes a risk to the human dental health of the region.

Published: March 2024

Polycyclic condensed quinazoline derivatives are biologically valuable compounds that have found their application in pharmaceutical and medicinal chemistry. Their practical use makes such compounds interesting and promising, and their synthesis is an urgent task. In the present work, the regio- and stereo-selectivity of the halocyclic reaction of propargyl thioethers of 2-thioxoquinazoline-4-one with bromine, iodine and iodine bromide, the effect of solvent polarity, acceptor substituent at position 7 of quinazoline, and the steric effect of the substituent at N(3) of quinazoline on the course of the electrophilic heterocyclic reaction were investigated. It was found that the halogenation of 3-alkyl-2-thioxo-2,3-dihydroquinazoline-4(1H)-ones in chloroform or ice-cold acetic acid proceeds regio- and stereo-selectively with the formation of salt-like thiazoloquinazoline halides. On the contrary, the stereoselectivity of halogenation of the 3-phenyl substituted propargyl thioether of quinazoline depends on the polarity of the solvent and in chloroform leads to the formation of a mixture of configurational isomers of thiazoloquinazoline tribromide, while in acetic acid, presumably, one geometric isomer is formed. The structure of the obtained polycyclic systems was proved on the basis of NMR spectroscopy and elemental analysis.

Keywords: propargyl thioethers; halogenation; stereo-selectivity; regio-selectivity; thiazoloquinazoline halides.

The health risk of polychlorinated biphenyls (PCBs) exposure from Ugbuwangue, Ugbori and Edjeba rivers sediments in Warri-South, Warri, Delta State was investigated. Nine sediment samples were collected; three samples each along the course of the different rivers. The sediment samples were Soxhlet extracted with acetone/dichloromethane/nhexane (1:1:1 v/v). A total of 28 PCBs were quantified using gas chromatography coupled with mass spectrometry detector. The concentration of the 28 PCBs ranges from 178.76-1398.29 ng g−1 for Ugbuwangue river, 224.81-685.19 ng g-1 for Ugbori river and 539.33-7858.3 ng g−1 for Edjeba river. The concentration of 12 PCBs were recorded for dioxin-like PCBs ranged from 0.08-401.52 ng g−1 (Ugbuwangue river 0.13 to 223.11 ng g−1, Ugbori river 0.08 to 153.39 ng g−1 and Edjeba river 0.32 to 401.52 ng g−1), while the concentration of 16 non-dioxin-like PCBs were recorded ranging from 0.13-4245.71 ng g−1 (Ugbuwangue river 0.18 to 386.47 ng g−1, Ugbori river 0.13 to 111.98 ng g−1 and Edjeba river 0.31 to 4245.71 ng g−1). The ecological risks of the nine sediment samples were investigated and it ranges from 25.52 – 1122.616 with Edjeba river sediment having the highest ecological risk while Ugbuwangue river sediment has the least ecological risk.
Trinity and Creation: Bavinck on the Vestigia Trinitatis
Authors: Doornbos Gayle
Published: March 2024

Engaging recent scholarship on Bavinck’s revitalization of the vestigia trinitatis and its connection to the organic motif, this essay identifies and examines two aspects of Bavinck’s account that remain underdeveloped with scholarship on this topic. First, it explores the lingering importance triads within Bavinck’s account of the vestigia. Bavinck may have developed a primarily non-numerical account of the vestigia, but he still acknowledges the place of triadic analogies, especially in humanity. Second, it contextualizes Bavinck’s appropriation of the vestigia within his understanding of creation as relative, divine, self-communication in order to illuminate how creation can bear the imprint of the Trinity even as the Trinity remains unlike anything in creation. Much work has been done on Bavinck’s triniform account of creation and his organic cosmology, but these accounts can often miss or gloss over the doctrines that Bavinck utilizes to carefully guards against a direct correlation between God and creation.
Mutual Misunderstandings: Herman Bavinck and Dumitru Staniloae in Dialogue
Authors: Simpson Robert
Published: March 2024

This paper examines the criticisms of Protestantism articulated by Romanian Eastern Orthodox theologian Dumitru Staniloae, highlighting over-generalizations in his assessments. Staniloae contends that Protestantism embodies dualism, anthropological pessimism, denigration of the sacraments, and indifference to sin, among other issues. This paper argues that some of these assertions reveal a lack of serious engagement and perhaps comprehension of the diverse range of the Protestant tradition. By scrutinizing Staniloae’s contentions through conversing with neo-Calvinist theologian Herman Bavinck, this paper attempts to demonstrate possible misinterpretations in Staniloae’s evaluations related to Protestant soteriology. In the reverse, the paper also evaluates some of Bavinck’s claims related to Palamist thought. Ultimately, this examination confirms that many of Staniloae’s criticisms of Protestantism are misinformed, just as Bavinck’s criticisms of Palamist thought lack both nuance and depth. By engaging in theological dialogue between these two theologians, this paper hopes to promote a greater appreciation for both traditions and the potential for further dialogue.

Published: March 2024

Effective power regulation is critical for ensuring the stability and performance of Doubly Fed Induction Generator (DFIG)-based wind turbines. This study conducts a comparative study between two control methodologies: fuzzy logic control (FLC) and sliding mode control (SMC), to regulate power in DFIG-based wind turbines. The paper emphasizes the importance of power regulation in wind turbines and its impact on grid stability, presents mathematical equations governing DFIG-based wind turbine systems, encompassing machine equations, power equations, and control objectives related to power regulation. A comprehensive model of the DFIG-based wind turbine system is developed, accounting for dynamic machine behavior and grid interface considerations. The modeli ng process integrates relevant electrical and mechanical components, along with power regulation control strategies. Subsequently, FLC and SMC control methodologies are developed and implemented to regulate desired power. Detailed discussions on controller design and tuning are provided, aligning with specific power control requirements. The results highlight SMC’s effectiveness in achieving precise power regulation within DFIG-based wind turbines, showcasing its superior response characteristics. The study offers valuable insights into the advantages and trade-offs associated with each control approach, aiding researchers and practitioners in selecting the most suitable control methodology for their operational needs. In summary, this paper contributes to the field of wind turbine control systems through a comparative study of FLC and SMC controllers, focusing on regulating power in DFIG-based wind turbines. The findings demonstrate SMC’s superior performance in response, enhancing our understanding of control methodologies for optimizing wind turbine performance and grid integration in sustainable energy systems.
A Model of Students’ COVID-19 Stress and Burnout at a Minority Serving College
Authors: Cox Jeanie K. , Camparo Lorinda B. , Yuen C. Nathalie
Published: March 2024

The coronavirus pandemic altered lives worldwide. COVID-19 negatively impacted mental health for college students (Zimmermann et al., 2021), with students experiencing increased feelings of anxiety, depression, and emotional distress, even after schools resumed in-person classes (Zheng et al., 2021). Previous research has investigated negative outcomes of COVID-19 (e.g., higher depression and anxiety, lower GPA), but few studies have investigated potential intermediate factors that might precede those negative outcomes. To examine potential intermediate factors between perceptions of COVID-19 and these well-documented negative outcomes, we used Koeske and Koeske’s (1991) Demand→Stress→Burnout→Outcome model. Between September 2021 and February 2022, a total of 116 participants from a small minority-serving undergraduate liberal arts college participated in this study through the use of an online survey. Participants were asked to report their fear of and perceptions about the seriousness of COVID-19; these items served as the “demand” in our model. We next asked participants to report their Stress, Personal Burnout, and Work/School Burnout, and we conducted a path analysis to test the model. The resulting model was a good fit to the data, χ2(5) = 8.10, p = .15, CFI = 0.99, TLI = 0.98, RMSEA = .07, SRMR = .05. Our findings suggest that helping students cope with the stress and burnout associated with COVID-19 may be a useful point of intervention for reducing anxiety and depression.
Da (in)aplicabilidade da lei dos compromissos e pagamentos em atraso aos serviços municipalizados de natureza mercantil (comentário ao acórdão do Tribunal Constitucional n.º 109/2015)
Authors: Pacheco de Amorim João , Ferreira Fausto , Teixeira Frédéric
Published: March 2024

No início da segunda década deste século, a sustentabilidade do sistema financeiro público nacional e a assunção de novos compromissos internacionais por parte do Estado, no âmbito da vigência do Programa de Assistência Económica e Financeira celebrado com a União Europeia, o Fundo Monetário Internacional e o Banco Central Europeu, impuseram a criação de mecanismos de controlo da execução orçamental e da despesa pública aptos a assegurar o cumprimento das obrigações internacionais a que o país se tinha vinculado.
Nesse sentido, foi aprovada a Lei n.o 8/2012, de 17 de março, designada por Lei dos Compromissos e dos Pagamentos em Atraso (LCPA), que “estabelece as regras aplicáveis à assunção de compromissos e aos pagamentos em atraso das entidades públicas”, e consequentemente é aprovado também o diploma que desenvolve as bases gerais e princípios da LPCA – o Decreto-Lei n.o 127/2012, de 21 de Junho. A LCPA vem restringir consideravelmente a capacidade de decisão financeira pública, e, no que concerne aos municípios, a respetiva autonomia financeira – consagrada nos artigos 6.o, n.o 1 e 235.o e seguintes da Constituição. E é neste contexto que se desenvolve o nosso trabalho, no qual se analisa o Acórdão do Tribunal Constitucional n.o 109/2015, bem como o Acórdão recorrido do Tribunal de Contas - n.o 2/2013, 1.a S/SS. A questão fundamental passa por saber se os serviços municipalizados com natureza mercantil estão ou não abrangidos pelo âmbito subjetivo de aplicação da LCPA e pelo diploma que a regulamenta. Como segunda questão surge também a necessidade de se aferir da inconstitucionalidade ou não dos normativos dos artigos 2.o da LPCA e do Decreto-Lei 127/2012, quando interpretados no sentido de se incluírem no respetivo âmbito de aplicação os serviços municipalizados com natureza mercantil. Os Acórdãos referidos do Tribunal de Contas e do Tribunal Constitucional (sob anotação) sustentam que a LCA e o diploma que a regulamenta abrangem os serviços municipalizados com natureza mercantil. A nossa posição é contrária a este entendimento, pois entendemos que não ser este constitucionalmente admissível, como procuramos fundamentar de seguida.
Product liability in the age of AI — Proposal for a “two track” solution
Authors: Mayrhofer Ann-Kristin
Published: March 2024

In 1985 the Council of the European Communities adopted the Directive 85/374/EEC to harmonise product liability within Europe. In 2024, this directive will most likely be replaced by a new Product Liability Directive designed to reflect the technical developments of the last 40 years. The new Directive contains some significant changes. However, regarding the overarching concept of product liability, it remains faithful to the old Directive: Manufacturers are still not liable for all damage caused by their products, but only for damage caused by a “defect” in a product. This defect-based approach is problematic. When it comes to new digital technologies, especially Artificial Intelligence, it is difficult for courts to assess a product’s defectiveness. Moreover, in many cases, the defect-based approach is insufficient to provide liability solutions that are both efficient and fair.
This paper seeks to lay the foundations for a more comprehensive reform: The current product liability for defective products should be complemented by a second “track” of product liability. In the case of particularly dangerous products, such as autonomous cars and medical devices, manufacturers should compensate victims regardless of whether their products are defective or not. Such “truly” strict liability could partially relieve courts of the burden of assessing a product’s defectiveness and would lead to fair and efficient prevention and distribution of damages. Damage costs would be allocated to manufacturers as the cheapest cost avoiders. In addition, the advantages and disadvantages of dangerous products would be more evenly distributed among manufacturers, users, consumers and “innocent bystanders”.
However, to avoid over-deterrence and stifling of innovations strict liability should be limited to particularly dangerous products. Legislators should introduce a general clause of truly strict liability, which would allow courts to assess whether a product is particularly dangerous or not. A general clause is preferable to a list of particularly dangerous products because it would provide for the flexibility needed to deal with rapidly developing technologies.

Introduction. Pandemic of the new coronavirus infection 2019–2021. has become a serious test of the country’s health care system, mobilizing all possible resources of the health care system.

The purpose of the study: a medical and statistical analysis of the contingent of patients in emergency hospitals during the COVID-19 pandemic.

Materials and methods. Data from federal state statistics (sources — FSN No. 14 and 30, 2019–2021) of 2 multidisciplinary hospitals operating in emergency hospitals (24/7/365) with fundamental structural and functional features related to the availability of beds for patients with a new coronavirus infection. Regulatory, statistical and analytical methods were used.

Study results. The main factor contributing to the differences in the organization of the work of ambulance hospitals was the factor of their re-profiling to receive infectious patients — the deployment of beds for patients with COVID-19, the second — the assignment of additional volumes of specialized non-infectious medical care to non-infectious hospitals for emergency hospitalization, change routing schemes in the implementation of medical evacuation of patients to specialized hospitals. These factors determined the dynamics of the patient population in these beds. The reduction (termination) of planned hospitalization, sanitary and epidemiological restrictions and quarantine measures were also significant.

Published: March 2024

Despite the success of recent decades in reducing mortality from diseases of the circulatory system (CVD), cardiovascular disease (CVD) remains the most common non-communicable pathology in all countries of the world. CVDs have high rates of morbidity, disability, and mortality. The most common of these are arterial hypertension and coronary heart disease. CVD occurs against the background of the presence of risk factors (RF). The ability to timely detect risk factors and manage their level underlies the prevention of CVD. Monitoring the level of risk factors at the individual level and assessing their prevalence at the group level is not feasible without the use of specialized software. Registration and monitoring of patients in the program allows you to create a data archive for use by medical professionals and the patient himself. In the literature there is information about the prevention and medical examination of the population with cardiovascular diseases. However, to date, the medical and social problems of FR management in CVD have not been sufficiently described. In this regard, the effectiveness of measures carried out within the framework of prevention and medical examination decreases.

The fight against diseases of the CVD group has not only social, but also economic significance. High rates of temporary disability and disability of patients lead to serious losses at the state level. This determines the need for further improvement of mechanisms for the prevention and treatment of CVD.

Published: March 2024

Acute dissection of aortic refers to cardiovascular catastrophes accompanied by a high level of fatal complications and deaths. In the vast majority of cases, middle-aged and elderly men with a burdened history of arterial hypertension and atherosclerosis suffer from this ailment. However, in addition to these diseases, this pathology can occur with rheumatism, inflammatory vascular diseases and connective tissue diseases. The polysymptomicity of the disease provides a high probability of meeting with this pathology of doctors of any specialization. Focusing on the clinical manifestations of the disease, taking into account laboratory (activation of prothrombotic and fibrinolytic mechanisms of the hemostasis system) and instrumental data will direct to timely recognition of pathology and diagnosis, which will determine the tactics of management and prognosis of the patient’s life. The disease in question is an absolute indication for surgical treatment, therefore conservative therapy will be aimed only at stabilizing hemodynamic parameters and preparing for surgical treatment of the patient. A clinical case of dissection of an aortic aneurysm, which occurred under the masks of acute coronary syndrome and acute abdomen, is presented. This case demonstrates the importance of assessing clinical symptoms and the dynamics of their development in the diagnosis of acute aortic dissection for doctors of both therapeutic and surgical profiles.

Authors: Paramita Sinta , Aulia Sisca , Rusdi Farid
Published: March 2024

In 2023, various music concerts will begin to be held nationally and internationally. Indonesian music fans came in droves to enliven the music concert. Audience music concert activities do not only focus on concerts and purchasing concert tickets but also on crowds in the virtual sector. The activity of watching a music concert is documented and uploaded via social media and Instagram. The use of hashtags is used to support the concert as well as being a means of self-actualization as a music fan. Uploads on Instagram social media with the hashtag immediately received attention from other social media users who were interested in the concert. From this explanation, this research will look at two things. Firstly, how influential hashtags on Instagram are in increasing audience engagement through three music concerts held in Indonesia. Second, look at the comparison of the three music concert hashtags. The research approach used in this research is quantitative, using extensive data-based social network analysis (SNA) methods. The application used in this research is Analisia.io, an artificial intelligence (AI) social analytic application as a tool for collecting virtual data according to the researchers' criteria. The first result of this research is that #blackpinkworldtourjakarta's cumulative total audience engagement is 17,653. #the90festival cumulative total audience engagement 144,150. And #coldplayjakarta, the total audience engagement was 811,387. The first Instagram hashtag most discussed virally is #coldplayjakarta, the second is the hashtag #the90festival, and the last is the hashtag #blackpinkworldtourjakarta. From this analysis, Instagram hashtag comparison activities in increasing audience engagement through music concerts in Indonesia fall into the concept of a network society: timelessness, the cultural consequences of information capitalism, the power of identity, and changing times.
Dynamics Simulation of a Small Satellite with a Robotic Manipulator for Additive Manufacturing
Authors: Spicer Randy , Black Jonathan
Published: March 2024

In-space manufacturing is an emerging concept that offers several benefits when compared with traditional space structures that are built on the ground and launched fully assembled. Structures manufactured in space are not limited by launch vehicle fairing volumes and do not require reinforcement to survive the ascent to orbit. Additive manufacturing is uniquely suited to this paradigm and has been proposed as a key piece of several in-space manufacturing architectures. However, the complex dynamics involved with 3D printing a structure on-orbit require additional study. Controlling a spacecraft with an attached multijointed, independently articulated robot arm is a complicated problem, and additive manufacturing is especially difficult due to the large tool paths required to complete a structure. Here, a numerical model of a free-flying small satellite with an attached robotic arm assembly is presented. Simulations for multiple 3D structures printed on-orbit and analysis of the small satellite controls required to stabilize the articulated arm are described. Multiple spacecraft control strategies are implemented, with resource utilization tracked throughout the simulation. The results demonstrate the feasibility of a small satellite platform for hosting a 3D printing robotic arm in space, and the simulation can be used to inform the design of future small satellite systems attempting complicated on-orbit manufacturing missions.

Solutions To Differences In Sentences For Parallel Integration Of Restorative Justice In Indonesian Courts
Authors: Bakhtiar Handar Subhandi , Amriyanto Amriyanto , Maddussila Samsu Alam
Published: March 2024

This study describes the problems and solutions related to differentiating sentences for the parallel integration of restorative justice in Indonesian courts. This study is normative-legal research using statute, comparative, and conceptual approaches. This study utilizes primary legal materials and secondary legal materials. This study is based on 25 (twenty-five) cases decided by judges in Indonesian courts. The research results indicate that the values of restorative justice are very relevant to the cultural values of gotong royong in Indonesia. Judges must consider the community’s cultural values and the implementation of restorative justice in their decisions. Parallel integration of justice has been re-applied in Indonesian courts. Still, in practice, judges do not have guidelines for parallel integration, so it is very possible that there will be differences in punishment for applying parallel integration. Therefore, as a solution to the problem of differentiation of sentences, the authors propose 2 (two) concepts of court decisions, namely (1) the verdict of the indictment cannot be accepted, and (2) the decision of the public prosecutor cannot be accepted.
Isotonic hydroxyethyl starch is ineffective in restoring blood pressure during experimental septic shock: Implications for fluid resuscitation strategies
Authors: Santiago Michael B. , Vilela Fabiana C. , Giusti-Paiva Alexandre
Published: March 2024

Objectives:

The objectives of the study were to evaluate the effect of isotonic or hypertonic hydroxyethyl starch (HES) solutions on blood pressure and to assess the influence of the neurohypophyseal system on this response during experimental septic shock. Male Wistar rats were randomly allocated to undergo either cecal and ligation puncture (CLP) or a simulated surgical procedure (sham).

Materials and Methods:

Of 6 h post-surgery, either isotonic saline (0.9% sodium chloride, 4 mL/kg), isotonic (HES; at doses of 4, 8 or 16 mL/kg), or hypertonic saline-HES (HS-HES; 4 mL/kg) was administered through the endovenous route, followed by the recording of blood pressure and heart rate. In addition, the levels of sodium, vasopressin, and oxytocin were evaluated after the fluid infusion.

Results:

The administration of HES did not have a significant effect on blood pressure in our study. However, the HS-HES solution increased plasma osmolality, sodium, vasopressin, and oxytocin levels. Furthermore, the HS-HES induced a transient elevation in blood pressure immediately after infusion, which could be completely blunted by the pre-administration of a V1-vasopressin antagonist.

Conclusion:

Our results demonstrate that the infusion of an isotonic blood volume expander during experimental septic shock is ineffective in restoring blood pressure due to blood vessel compliance. In contrast, the infusion of a hypertonic solution stimulates vasopressin secretion and can transiently restore blood pressure.
VARIATIONS IN FREQUENCY AND AMPLITUDE OF NONSPECIFIC ELECTRODERMAL RESPONSES
Authors: Bari Dindar S.
Published: March 2024

Electrodermal activity (EDA) represents changes in the electrical properties of the skin due to the opening of sweat pores and sweat secretion. EDA responses are classified into specific and nonspecific responses. Nonspecific EDA responses (NS.EDRs) are EDA responses without external stimuli or motor activity and are shown to be a good measure of psychophysiological states and traits. Studies investigating NSEDRs are rare, especially on responses, which occur following specific responses at resting periods. This study aimed to investigate variations in NS.EDRs  (in terms of frequency and amplitude) at a sequence of resting periods (pre and post of various stimuli). NS.EDRs parameters were recorded from 20 subjects simultaneously in the same skin area. They were computed at resting periods before and following specific responses due to five external stimuli. The study results indicated that there were differences in the frequency and amplitude of NS.EDRs recorded at different resting periods. Additionally, the frequency of NS.EDRs obtained before stimuli were more than those detected at other resting periods, whereas amplitudes of NS.EDRs following sound stimulus were higher than those computed before and after other stimuli; however, these results were statistically nonsignificant (p>0.05). This study suggests that nonspecific skin potential responses (NS.SPRs) are very sensitive to capture variations in the frequency and amplitude of NS.EDRs, whereas nonspecific skin susceptance responses (NS.SSRs) are the least sensitive compared to nonspecific skin conductance responses (NS.SCRs) and NS.SPRs. NS.EDRs may be an important indicator for tracking arousal, emotional behavior, psychophysiological variables, and goal-directed thinking in clinical applications due to their sensitivity to such responses.

On 28 November 2023, within the framework of the All–Russian meeting of heads of federal and central regional libraries of Russia, the winners of the next All– Russian competition of scientifi c papers on library science, bibliography and book studies were solemnly awarded. On behalf of the Ministry of Culture of the Russian Federation, the competition was organized by the Russian National Library and co-organized by the Russian State Library with the support of the Russian Library Association. The competition is one of the main tools for assessing the effectiveness of scientifi c activity in the fi eld of librarianship. The competition contributes to the support and development of science in librarianship within the framework of the “Strategy for the development of librarianship in the Russian Federation for the period up to 2030” and meets the objectives set by the President of the Russian Federation in the “Fundamentals of State Cultural Policy” in the fi eld of development of research of social and humanitarian nature.
Russian Bindings of the 1780s—1790s with Endpapers Made of Decorative Block-Printed Paper

Published: March 2024

One of the most difficult tasks in the study of bindings of old printed books is to determine the time of their manufacture in the absence of a date affixed by the bookbinder or the customer and other documented information. The study attempts to identify the characteristic features of Russian bindings of the last two decades of the 18th century, based on a group of bindings united by one material — decorative flyleaf paper with block-printed pattern. The article tells about the history of the manufacture of such decorative papers in Europe and Russia in the 18th century, about the types of printed drawings of Russian papers and the peculiarities of their use in bookbinding. Endpapers made of block-printed paper became one of the characteristic features of Russian bindings of the 1780s—1790s. The research is based on books printed in Moscow printing houses from the collection of publications of the civil press of the 18th century in the Department of Rare Books of the Russian State Library (Book Museum). There were 1080 books in-octavo format of the 1780s—1790s were selected in solid-leather bindings only with block-printed endpapers, their design and decorative features were identified and described. The analysis showed that such endpaper was almost always combined in the binding with marbled calfskin of a special pattern as a cover material, which can be considered as a sign of a special genre of binding. His other features: the method of fastening the endpapers, the absence of a headband and ribbon or cord bookmarks, characteristic stamping stamps — are non-specific, but also quite regular, so they can be used for more accurate dating and other domestic bindings of the late 18th century.

Published: March 2024

The Great Patriotic War left a deep mark not only in official history, but also in the individual memory of many generations, and also influenced the formation of national mentality and historical self-perception. Diaries and memoirs of direct participants in those events are a valuable sources of historical information. The article provides a similar review of a number of fundamental scientific and auxiliary annotated indexes of memoir literature (relating to the period 1941—1945), prepared with the participation of bibliographers of the Russian State Library.
Reference and Bibliographic Services in Foreign National Libraries (Organizational Aspect)
Authors: Neshcheret Marina Yu.
Published: March 2024

Digitalization is changing the environment in which libraries operate. The processes of production, storage, dissemination and use of information are undergoing significant changes. Reference and bibliographic service in the operational mode “request — response” is the most sensitive to the ongoing transformations. The problem of developing an optimal functional and organisational model of reference and bibliographic service is of particular relevance. The article is devoted to the review and analysis of the organisation of reference and bibliographic services in ten national libraries of the world on the basis of monitoring of official sites. The author defines the main forms of reference and bibliographic services, communication channels and ways of interaction of reference and bibliographic services with users. Special attention is paid to the currently dominant multilevel service model and its modifications. The problem of the crisis of reference bureau — stationary point of reference and bibliographic service is considered as a private one. The main tendencies of modernization of reference and bibliographic service in the digital age are revealed. The key drivers of change, in the author’s opinion, are the desire to link the library more closely to institutional strategy and to provide enhanced research support to those who need it.
