Managerial style as an indicator of the nature of interaction between regional authorities and the population
Authors: Shilova Valentina
Published: July 2024

The article presents an analysis of respondents' perception of the regional management style as a factor characterizing the managerial communication system. Based on the secondary conceptualization of empirical data (6021 field documents) obtained in 2019-2020 in 12 regions of the Russian Federation during a self-filling questionnaire based on a quota sample calculated for each region according to Rosstat, the author conducted a study of the relationship between respondents' characteristics of the regional management style with agreement with it, concern about the shortcomings of the regional management system and assessments the work of the vertical of power from the federal to the local levels. The author identified a number of patterns, based on which it was concluded that groups of respondents who define the regional management style differently agree with it to varying degrees, demonstrate concern about the shortcomings of the characterized management system in different ways and evaluate the final result of the activities of the power and management vertical. Respondents who define the management style as authoritarian and clan-based tend to be more concerned about the shortcomings of the management system for the most part than respondents who characterize the management style as democratic, collegial, liberal or vague. Respondents who define the management style as authoritarian tend to evaluate the final result of the work of authorities at all levels lower than respondents who believe that the management style is democratic, collegial or uncertain.

Published: July 2024

Background: Effective nurse leadership significantly influences healthcare service quality. Nurse managers' leadership impacts staff nurse commitment, patient outcomes, and organizational success.
Aims: To examine nurse manager leadership traits and their relationship with staff nurse commitment in a government hospital.
Methods: Descriptive-inferential correlation research with stratified and randomized nurse managers (n = 21) and staff nurses (n = 117) as participants from five selected hospitals at Lanao del Norte. Adopted questionnaires on leadership traits and commitment were used and data were analyzed using frequency, percentage, mean, and standard deviation in SPSS v.25.
Results: The result shows that nurse manager leadership qualities are usually valid for a leader who encourages others to do what is right, gives subordinates continuing education, and is an ethical and self-confident leader. Their staff nurses believed positive components of the leadership traits of nurse managers were sometimes true. Staff nurses were generally still deciding whether they were committed to their work effectively, continuously, or normatively. Nurse managers' leadership traits are significantly related to the staff nurses' affective, continuance, and normative commitment.
Conclusion: Fostering positive leadership through education and supportive environments enhances staff nurse commitment and job satisfaction, reducing nurse turnover and improving nursing care quality.

Hepatic arterial infusion chemotherapy: a review with technical notes
Authors: Stecca Tommaso , Greco Alessandra , Brollo Pier Paolo , Massani Marco
Published: July 2024

Combined hepatic artery infusion (HAI) and systemic chemotherapy have demonstrated its clinical efficacy in prolonging overall survival in unresectable intrahepatic cholangiocarcinoma and as a conversion to treatment strategy in a small proportion of patients. The utilization of HAI chemotherapy is restricted by the scarcity of surgeons and oncologists who are well-experienced in its use. This represents a significant drawback of this treatment method. In recent years, a solid push to expand its use, mainly in the United States and recently also in Europe, has been made possible by the HAI Consortium Research Network. Results of ongoing Clinical Trials are eagerly awaited to give the basis for further expansion of this technique and oncological treatment outside of historically established centers. In this technical note review, we aim to give a brief historical description of the origins and evolution of intra-arterial chemotherapy for unresectable intrahepatic cholangiocarcinoma. We will, therefore, discuss the surgical technique by providing some tips and tricks without neglecting the difficulties that may be encountered.
The recent progress of single-atom catalysts on amorphous substrates for electrocatalysis
Authors: Liu Cheng’ao , Cui Yanping , Zhou Yao
Published: July 2024

Single-atom catalysts (SACs) have emerged as a focal point in energy catalytic conversion due to their remarkable atomic efficiency and catalytic performance. The challenge lies in efficiently anchoring active sites on a specific substrate to prevent agglomeration, maximizing their effectiveness. Substrate characteristics play a pivotal role in shaping the catalytic performance of SACs, influencing the dispersion and stability of single atoms. In recent years, amorphous materials have gained attention as substrates due to their unique surface structure and abundance of unsaturated coordination sites, offering an ideal platform for capturing and anchoring single atoms effectively, thus enhancing catalytic activity. To clarify the interaction between single atoms and amorphous substrates, this review outlines amorphization methods, the mechanism of single-atom anchoring and the characterization methods of amorphous SACs. Subsequently, it summarizes the physical properties and electrocatalytic mechanisms of amorphous materials. Then, interactions between single atoms and amorphous substrates are categorized and summarized. Finally, the paper consolidates the research progress of amorphous SACs and outlines future development prospects. By exploring the synergistic relationship between single atoms and amorphous substrates, this review aims to deepen the understanding of their interaction mechanisms, thereby propelling advancements in SACs for energy catalytic conversion.
Neuropathy and pain in Fabry disease
Authors: Medala Vijay Krishna , Üçeyler Nurcan
Published: July 2024

Fabry disease (FD) is a multiorgan lysosomal storage disorder caused by mutations in the alfa-galactosidase A (GLA ) gene. Pathogenic GLA mutations lead to impaired or even lost enzyme activity, which causes the accumulation of sphingolipids, e.g., globotriaosylceramide, in cells and tissues. The majority of FD patients experience triggerable pain, mainly acral and burning, which often begins in early childhood. While small fiber pathology is assumed to be the basis of FD pain, the underlying molecular mechanisms are not well understood. This review summarizes the clinical characteristics of neuropathy and neuropathic pain in FD, presents current treatment options, and gives an overview of the latest findings from experimental and human model systems on the pathomechanisms contributing to small fiber pathology and FD-associated pain.

The development of airport security screening systems requires the use of increasingly sophisticated and effective equipment to detect prohibited or hazardous items and substances. However, this can lead to a reduction in the throughput of the security checkpoint (SCP). This paper addresses the operationally important problem of the dilemma between screening effectiveness and screening checkpoint throughput, which is important to the real operational capabilities of an airport. In this paper, a comparison of traditional walk-through metal detectors (WTMD) gates and newer technology body scanners (BSs) was carried out in terms of SCP throughput as an element determining the operational capabilities of the airport. For this purpose, a simulation model was developed to study throughput based on a colored timed Petri net. The analysis showed that, depending on the characteristics of the available staff, the level of terrorist and epidemic threat, as well as the time of year, it is advantageous to use different strategies to vary the size of the stream of passengers directed for screening by the WTMD gate and BS.
TRANSPORT SYSTEM PLANNING: INTERACTION BETWEEN CAPACITY UTILIZATION AND TRAFFIC CONGESTION IN NIGERIA
Authors: ADERIBIGBE Oluwayemi-Oniya , GUMBO Trynos , DEJI Joseph
Published: July 2024

One of the greatest challenges most developing countries are facing is the need to improve the transportation systems in their cities. In achieving this, emphasis has been put on the role of infrastructure development to improve the mobility of residents and reduce the negative externalities, such as traffic congestion, associated with most cities in both developed and developing countries. Hence, this study evaluates the impact traffic volume, in relation to available infrastructure capacity, has on traffic congestion, within the dynamics of a rapidly developing urban environment. Though there appears to be a consistent state of slow-moving traffic on two of the roads studied, traffic congestion is not critical, which suggests that available infrastructure is being appropriately utilized. This study found a statistically significant negative relationship between capacity utilization and traffic congestion levels.
RELATIONSHIPS BETWEEN MANAGERIAL CONCEPTS IN INLAND TRANSPORT COMPANIES: A FUZZY-DEMATEL APPROACH
Authors: CHARŁAMPOWICZ Jędrzej , MAŃKOWSKI Cezary
Published: July 2024

The axiom that the efficacy of supply chain entities is inextricably tied to the adoption of an appropriate management system is widely acknowledged. At the heart of such a system are managerial concepts. There is abundant literature with a variety of theories, concepts, methods, and tools aimed at managerial enhancement. However, there is a dearth of specific recommendations for their application, an understanding of their interdependencies, or discerning which concepts are causative and which are resultant in nature. The heterogeneous functions of supply chain participants preclude a universal best-practice array of these managerial concepts. By focusing on the pivotal role of inland transport firms within the supply chain, this study delineates an array of managerial concepts apt for such enterprises, employing the fuzzy-DEMATEL method. This study’s contribution is encapsulated in the identification of the structural, relational, and hierarchical configuration of managerial concepts that bolster the decision-making framework of inland transport management.

Authors: BOROWSKI Piotr F.
Published: July 2024

The integration and utilization of renewable energy sources in the energy and transport sectors are the main actions undertaken to attain climate neutrality by 2050. The connection and indication of the relations occurring in these two sectors constitute the novelty of the current research. Key actions include increasing the share of low- and zero-emission transport, such as electric cars, bicycles, trains, and buses; reducing emissions from aviation and shipping; and improving energy efficiency and transport safety by modernizing the vehicle fleet, introducing intelligent transport systems, applying emission and fuel quality standards, and promoting technological and digital innovation. A novel and significant aspect of the research is its comprehensive approach to key economic sectors that exert a profound influence on climate change. Through the conducted studies, it has been demonstrated what essential actions must be undertaken to transition towards a low or zero-emission economy. This paper points to a strong nexus between the transport sector, the energy sector, and climate change, underscoring the imperative for collaborative efforts and strategic initiatives among these sectors to address the pressing challenges associated with achieving climate neutrality.
CORRELATION STUDIES OF PROCESSES: VEHICLE VELOCITY, POLLUTANT EMISSIONS, AND VEHICLE FUEL CONSUMPTION IN THE WORLD-WIDE LIGHT-DUTY TEST CYCLE
Authors: SORDYL Adam , CHŁOPEK Zdzisław , MERKISZ Jerzy
Published: July 2024

The article presents the worldwide harmonized light-duty test cycle results of a diesel engine passenger vehicle carried out on a chassis dynamometer. Pollutant emissions from exhaust and fuel consumption were measured. Vehicle velocity was treated as a variable determining pollutant emissions and fuel consumption because the engine operating states depend on engine velocity and load during engine operation, and these states in turn affect pollutant emissions and fuel consumption. Actions taken to reduce pollutant emissions and consumption of fuel are often in opposition to each other. Therefore, there is a need to optimize these activities. There is also a need to know the relationship between the effects of taking specific actions that serve to achieve individual goals in order to rationalize actions aimed at reducing pollutant emissions and fuel use. The originality of the article lies in the use of the correlation theory between pollutant emission and fuel consumption as well as the processes that determine them, primarily vehicle velocity, to rationalize these activities. Pearson's linear correlation theory was used to assess the relationships between individual variables. Significant differences were found in the correlation coefficients between individual variables, which confirmed the need to take integrated actions to reduce pollutant emissions and fuel consumption.

Celem artykułu jest przedstawienie życia i działalności naukowej Ireny Grasberg Koprowskiej (1917-2012), polskiej lekarki, pionierki w dziedzinie cytopatologii. Ukończywszy Wydział Lekarski Uniwersytetu Warszawskiego, Koprowska rozpoczęła swoją medyczną karierę na emigracji, po ucieczce z Polski przed niemiecką agresją w 1939 r. Jako młody lekarz początkowo pracowała w laboratorium patologicznym, gdzie samodzielnie przeprowadziła setki autopsji, dochodząc do perfekcji w swoim fachu. W 1949 r. rozpoczęła współpracę z Georgem N. Papanicolaou i zaangażowała się w jego pionierskie działania na rzecz rozwoju cytopatologii oraz metod wczesnej diagnostyki nowotworów. Oprócz tego prowadziła własne badania eksperymentalne nad nowotworami, w szczególności nad rakiem szyjki macicy. Irena Koprowska była współautorką pierwszego na świcie opisu przypadku wykrycia carcinoma in situ w płucu za pomocą oceny rozmazu plwociny. W 1964 r. została pierwszą kobietą mianowaną tytułem profesora zwyczajnego w Hahnemann University w Filadelfii.

A pressing issue today is the analysis of the possibilities of using SF6 gas and its possible limitations of use from the point of view of harmful effects on the environment. The article, based on free sources of information, systematizes the historical facts of the development of SF6 gas, the main stages of the formation of the SF6 gas environment as insulation for electrical equipment. Comparative characteristics of electrical strength for various insulating substances are presented. Research has been carried out on modern examples of the use of SF6 gas in medium and high voltage circuit breakers. Examples of the use of SF6 gas and its mixtures as gas insulation for high-voltage power lines are analyzed. It is shown that a promising direction for the development of SF6 gas is its use in gas-insulated power lines. Design features and examples of practical application of high-voltage gas-insulated power lines are presented. The features of using SF6 insulation in electrical equipment of different voltage classes are determined. Current environmental problems associated with the use of SF6 gas are analyzed and possible directions for overcoming them are established. The elements of SF6 gas decomposition products that are toxic and pose the greatest danger are considered. The characteristics of SF6 gas as a greenhouse gas are given and promising ways to reduce its use are shown. It has been established that by using not pure SF6 gas, but gas mixtures based on it, it is possible to significantly reduce the percentage of SF6 gas use. Promising directions for further development of gas insulating medium for electrical equipment without the use of SF6 gas have been established.

In the article, the authors analysed the existing shielding systems of insulating structures of high-voltage devices together with electrodes under high potential. At the same time, the possibilities of using toroidal screens of various designs and the conditions of their installation in gas-filled equipment structures (gas-filled current and voltage measuring transformers, arresters, etc.) using polymer insulating materials are considered. Based on the analysis of literary sources, the most effective method of estimating the electric load parameters for determining the electric field strength distribution along the continuous insulating structure of gas-filled high-voltage devices with axial symmetry is proposed. This design is a support-insulating shell filled with SF6 as an internal insulating medium. Methodical materials are recommended that allow you to estimate the electrical load parameters (voltage and field strength) depending on the design features of the device and the shielding system used to level the electric field. Based on them, it is possible to evaluate the effectiveness of the calculation coefficients of the shielding system of gas-filled high-voltage equipment in the design process and during the improvement of individual design solutions. The results of the analytical evaluation by such methods are in good agreement with the data of experimental studies and statistical information obtained as a result of monitoring the work of insulating structures, taking into account real operating conditions and the influence of external factors. The introduction of the obtained materials allows you to take into account the influence of external factors and operational characteristics inherent in measuring transformers and overvoltage limiters. To explain the results of the analysis of methodical materials carried out in the article, as an example, the results of calculations of the support-insulation shell of the gas-filled current transformer of the TOG series, which was the most affected during operation, are given. in adverse conditions, given under such conditions as external pollution, humidity and their combination, as well as under conditions of overvoltage of various origins, etc. On the basis of the presented materials, it is possible to more accurately determine the effectiveness of various screenings. system, as well as how to predict the field strength distribution parameters under the influence of the shielding system, taking into account its design features. In addition, on the basis of the conclusions formed in the work, it is possible to plan and conduct an additional series of calculations and experimental tests taking into account the features of specific structures. Thus, the obtained results can be used to evaluate the external insulation parameters of both gas-filled measuring transformers and similar high-voltage equipment of distribution devices and transformer substations.

Low carbon steel cannot be hardened because of its low carbon content. Therefore, a hardfacing process is carried out to increase hardness. Apart from increasing hardness, the benefits of hardfacing can increase wear and corrosion resistance. The hardfacing process using the shielded metal arc welding (SMAW) process generally uses commercial electrodes. Therefore, it is necessary to add other elements such as titanium (Ti) to the weld layer to further increase its hardness. This research aims to study the influences of Titanium (Ti) addition in welding layers that were welded using HV 600 to micro and macrostructure, hardness, and corrosion rate. The hardfacing was conducted using the SMAW process with the various addition of Ti (0.115, 0.223, and 0.334 g) and cooled at room temperature. Macrostructure and microstructure were investigated using digital cameras and an optical microscope. Hardness and corrosion rate were investigated using the Vickers hardness test and weigh loss method. Based on macrostructure investigation, there is a perfect fusion between base metal and weld metal. The microstructure formed is a austenite, martensite and carbide phase. The lowest corrosion rate of 17.54 mpy was seen in the Ti1 sample. The lowest Ti addition would resulting higher hardness at 761.06 VHN.
