Ziemann and Oestmann showed that the impact factor of medical publications resulting from doctoral theses at the Charite University Hospital rose by 50% over a decade (4). Mooreover, the number of publications per doctoral candidate rose from 0.8 to 1.4.. These data have to be appreciated. Nevertheless, they should also prompt a discussion about the validity of the impact factor in comparison within faculties. Submitted manuscripts are carefully reviewed by editors/publishers and peer reviewers in order to determine a priority for publication. As a rule, suggestions are implemented aiming for improving the quality of the presentation and thus citations of the publication (1). In view of the current discussions on plagiarism, these hidden “external services” by reviewers that have not been involved in the study are not trivial. The impact factor of medical journals correlates with the number of journals publishing in this domain and the seize of the audience; this results in differences in cross-sectional fields, organ specialties, and subspecialties (2). This is facilitated by modern technologies and several scientific on-line services. Furthermore, formal rules are relevant for citation numbers (1). In general, excellent studies with a presumed scientific and medical impact are preferably published in top journals that do not belong to any particular medical specialty. As a result, the impact factor of journals publishing in a specific domain does not necessarily reflect the scientific potential of that specialty. This statement can be illustrated by current experience in pediatric oncology and hematology. In 2012, five researchers recently received prizes and honors, while their corresponding publications were all published in non-pediatric journals (3). The allocation by specialty for each individual publication is hardly able to abolish such imbalances (2) and appears unrealistic. However, a score that assigns points for the quartile-ranking of a journal within a discipline-specific list is easy to perform and should be considered. If such a score were used across disciplines to compare scientific achievements, the top journal still would retain their influence – however outside of discipline specific lists. Formal biases could be marginalized and disciplines that are currently at a disadvantage could win. This would then enable a valid comparison both within medical faculties and between faculties with different profiles.

Global policy identifies the need to achieve climate neutrality, especially in the most energy - intensive sectors of the economy, as a key focus. Climate neutrality is closely linked to the reduction of energy demand and the use of materials and technologies with a low embedded carbon footprint. The economic sector with some of the highest energy intensity and CO2 emissions is construction. In the case of newly designed buildings, most countries have already implemented measures to reduce energy demand by introducing a near - zero energy building standard (nZEB standard). The problem is not only the new built but mostly existing building stock, which requires deep thermo - modernisation measures. These measures will reduce energy consumption in the building sector and thus reduce emissions of harmful gases into the atmosphere. In the article, the authors, using the example of two countries with different climates: Poland and Vietnam, they analysed in terms of embedded carbon footprint the available technologies dedicated to thermal modernisation measures. The countries were chosen for the analysis because of the differences in climate that determine the scope of thermomodernisation measures taken. In the case of Poland, it is a temperate climate, where buildings should be designed to reduce heat loss in the winter season and ensure thermal comfort in the summer season. In the case of Vietnam, it is a humid subtropical climate, where the emphasis should be on protecting buildings from overheating. The analyses presented here show both traditional and modern innovative technologies used in the thermal modernisation of existing buildings. The analyses carried out by the authors show how modern technologies affect the thermal insulation of building partitions and thus reduce energy consumption. The article also presents analyses of the technologies in terms of the embedded carbon footprint, which characterises the phases of material manufacture. The conclusions presented by the authors allow informed choices to be made when deciding which materials and technologies to use for deep thermo - modernisation measures in existing buildings, so as to reduce energy demand and minimise the embedded carbon footprint.

Complexity, Maturity and Competency in the Project Risk Management Environment: A Relational Framework

The Qatari media system is emerging rapidly to cater for the rapid socio-economic change and sustainable development the country is witnessing since its independence in December 18th, 1997. Since the accession of H.H Sheikh Hamad Bin Khalifa AI Thani to the reins of the country, the media have been promoting freedom, democracy and social change. Qatari media are fostering Arab and Islamic heritage and morals as well as national, Arab and Islamic causes. Established in 1971, Qatar continues to undergo a period of intense socio-economic change. Although Qatar is a small nation in terms of area (4,416 sq mi) and population (2,116,400), it has one of the best media infrastructure in the region for press, broadcast, and electronic media. The country has four dailies in Arabic, three in English, and more than two hundred magazines of both general and specialized interest. Qatar also has several satellite television channels and radio stations, as well as the famous Al Jazeera network and be INSPORTS channels. I...

About Our Authors

The article discusses how Old Believers of different denominations perceive the transfer of religious life to the online environment and the usage of new technologies within traditional practices. The main sources are field research data obtained in 2020—2022 and online interviews with Old Believers from Russia and abroad (Lithuania, Latvia, Estonia, Romania, Republic of Moldova). Considering the attitudes towards online worship services and the use of modern technical means and media technologies to perform religious practices during the pandemic, the article examines how Old Believers search for answers about the extent to which the transformation of religious practices under the influence of mediatization is acceptable. Priestly Old Believers are more likely to positively perceive new technologies that allow them to expand missionary activities. As for the priestless Old Believers, most of the religious leaders and ordinary believers speak out against the active mediatization of traditional practices, since they no longer comply with the apostolic rules, while allowing the use of technical innovations and broadcasting of online worship services for educational purposes. Nevertheless, the variability of answers and interpretations can be traced not only at the level of different Old Believer denominations, but also within communities, while the region of residence does not play an important role in decision-making.

Green manufacturing represents a paradigm shift towards sustainable production processes that minimize environmental impact by reducing energy consumption and conserving natural resources. This paper explores green manufacturing strategies, focusing on the adoption of energy-efficient technologies, the use of recycled materials, and the redesign of manufacturing processes to minimize waste and emissions. The research highlights the importance of energy reduction at multiple system levels—process, equipment, facility, and supply chain—demonstrating how dynamic scheduling and modern technologies can lead to significant energy savings. The study emphasizes the growing need for industries to adopt green manufacturing practices as a response to global warming and environmental degradation, while also recognizing the financial benefits of reduced energy consumption. The integration of environmentally friendly designs, sustainable materials, and optimized energy usage throughout the manufacturing process is presented as crucial to achieving both economic and environmental sustainability in the manufacturing sector.

Increasing global warming is largely attributable to human activities. International strategies have already been implemented to reduce emissions to zero, thus reducing energy consumption. Given the current world situation and the rising costs of raw materials (gas and oil), it is incumbent on us to find savings solutions that can also be implemented in our own small way; there are many solutions, especially in the domestic sphere. In this paper, the focus is on building energy savings that can be achieved using modern technologies and starting with the simplest solutions. In particular, this paper shows how the conscious use of natural lighting can lead to significant electricity savings. Moreover, it describes the effect of innovative building insulation materials and the effect due to the installation of a local photovoltaic power generation system; at the end, it illustrates the new horizons that are opening with the introduction of new building control techniques. Some studies are also reported where the extent of achievable savings can be understood.

Street lighting systems are considered one of the most important pillars necessary for the infrastructure that must be provided in urban cities due to their positive impact on the lives of citizens. Street lighting provides comfort to citizens and makes them feel safe at night. Despite all these advantages, it brings a heavy burden on the energy consumption bill and has negative consequences for the environment. Modern technologies, such as wireless communications and the internet of things (IoT), have enabled the creation of smart street lighting systems that contribute to improving energy saving and preserving the environment compared to traditional systems. In this research, the performance and feasibility of a prototype smart street lighting system based on IoT and wireless communications were studied. This system was implemented and tested at a pilot site with the aim of enhancing energy performance and creating a smart infrastructure on the university campus. Street user data, captured by the passive infrared (PIR) sensor, is exchanged between lighting poles using the ESP-NOW protocol to create adaptive lighting. This ensures that the level of illumination by the LED luminaires around the user is greater than that behind them. The cloud server ThingSpeak was also utilized to collect and store the electrical variable data measured by this system. Additionally, images are captured and stored for street users. From the data obtained from the cloud server and energy measurements, the system has demonstrated its effectiveness in reducing energy consumption.

Lithium, a critical element for clean energy and modern technologies, plays an indispensable role in advancing renewable energy storage, electric vehicles, and high-tech industries. The rapidly growing demand for lithium, along with its limited global production, has led to concerns about the sustainability of current extraction and processing technologies for efficient lithium recovery. This comprehensive review explores global trends in lithium processing, focusing on spodumene beneficiation and extraction techniques. While highlighting well-established conventional processes, such as dense media separation (DMS), flotation, high-temperature roasting, and acid or alkali treatment, it underscores the environmental and economic challenges of these processes, particularly when applied to low-grade lithium ores, which are increasingly being targeted to meet lithium demand. Innovative methods, such as microwave irradiation, are also explored for their potential to improve process efficiency, reduce energy consumption, and minimize environmental impact, offering promising pathways to overcome the limitations of traditional lithium recovery techniques. A significant contribution of this review is its focus on the largely untapped lithium resources of Kazakhstan, presenting geological insights and the potential for sustainable development. By addressing knowledge gaps and integrating technological, eco-friendly, and regional development perspectives, this study provides valuable insights for advancing lithium processing toward more sustainable and circular practices aligned with global climate and resource efficiency goals.

Abstract. Single point incremental forming (SPIF) is a modern rapid manufacturing technology able to manufacturing complex sheet parts in small quantities. In comparison to conventional deep-drawing process, complex tools can be dispensed in order to reduce tool costs and the time required to achieve the first finished part. This new technology consists of locally and iteratively deforming plastically the sheet material by a punch that is generally hemispherical and of small dimensions, whose trajectory is programmed on a numerically controlled machine or a robot arm. The parts formed are mainly made from metallic materials (steel, aluminum, titanium or copper alloys). Very few studies focus on the incremental forming of thermoplastic parts. Because of the poor formability of thermoplastic parts and the large spring-back at room temperature, the use of heating systems of the work-piece during the forming process is required. In this work, a novel incremental sheet forming assisted by heat transfer was developed to improve the formability of thermoplastic sheet. By means of a series of experimental forming of High Impact Polystyrene pyramid frustum with constant wall angle at different heat temperatures, geometric accuracy was recorded and analyzed. This study aims to evaluate the behavior of polymer material in the hot incremental sheet forming with different pre-heating system using the finite element method.
