The α-fractional power moduli series are introduced as a generalization of α-fractional power series and the structural properties of these series are investigated. Using the fractional Taylor’s formula, sufficient conditions for a function to be represented as an α-fractional power moduli series are established. Beyond theoretical formulations, a practical method to represent solutions to boundary value problems for fractional differential equations as α-fractional power series is discussed. Finally, α-analytic functions on an open interval I are defined, and it is shown that a non-constant function is α-analytic on I if and only if 1/α is a positive integer and the function is real analytic on I.

Fe-Mn-Cr-Ni alloys like Citomangan, delivered in the form of powders, tubular wires, and coated electrodes, are intended for welding deposition operations to create wear-resistant layers. Their main characteristic is their high capacity for surface mechanical work-hardening under high shock loads, along with high toughness and wear resistance. In order to increase the resistance to cavitation erosion, hardfacing of Duplex stainless steel X2CrNiMoN22-5-3 with Citomangan alloy was performed using a new welding technique, namely one that uses a universal TIG source adapted for manual welding with a coated electrode in pulsed current. Cavitation tests were conducted in accordance with the requirements of ASTM G32—2016 standard. Comparing the characteristic cavitation erosion parameters of the manganese austenitic layer, deposited by this new welding technique, with those of the reference steel, highlights an 8–11 times increase in its resistance to cavitation erosion. Metallographic investigations by optical microscopy and scanning electron microscopy (SEM), as well as hardness measurements, were carried out to understand the cavitation phenomena.

Background and Objectives: The implications of the genetic component in the initiation and development of chronic lymphoproliferative disorders have been the subject of intense research efforts. Some of the most important genes involved in the occurrence and evolution of these pathologies are the HLA genes. The aim of this study is to analyze, for the first time, possible associations between chronic lymphoproliferative diseases and certain HLA alleles in the Romanian population. Materials and Methods: This study included 38 patients with chronic lymphoproliferative disorders, diagnosed between 2021 and 2022 at Fundeni Clinical Institute, Bucharest, Romania, and 50 healthy controls. HLA class I and class II genes (HLA-A/B/C, HLA-DQB1/DPB1/DRB1) were investigated by doing high resolution genotyping using sequence specific primers (SSP). Results: Several HLA alleles were strongly associated with chronic lymphoproliferative disorders. The most important finding was that the HLA-C*02:02 (p = 0.002, OR = 1.101), and HLA-C*12:02 (p = 0.002, OR = 1.101) have a predisposing role in the development of chronic lymphoproliferative disorders. Moreover, we identified that HLA-A*11:01 (p = 0.01, OR = 0.16), HLA-B*35:02 (p = 0.037, OR = 0.94), HLA-B*81:01 (p = 0.037, OR = 0.94), HLA-C*07:02 (p = 0.036, OR = 0.34), HLA-DRB1*11:01 (p = 0.021, OR = 0.19), and HLA-DRB1*13:02 (p = 0.037, OR = 0.94), alleles have protective roles. Conclusions: Our study indicates that HLA-C*02:02 and HLA-C*12:02 are positively associated with chronic lymphoproliferative disorders for our Romanian patients while HLA-DRB1*11:01, HLA-DRB1*13:02, and HLA-B*35:02 alleles have a protective role against these diseases.

The periods of warming and cooling of the weather on Earth followed one another with great irregularity and caused significant variations in air temperature but allowed the existence of life and especially of the human species. In this paper we have analysed the variation of air temperature in Oltenia in the period 1961-2021. A number of our other works have analysed the variability of the climate in this part of Romania. After the warm period of 1945-1955, a gradual cooling of the weather followed in summers and during the period 1966-1984 (for 20 years). In summers, no thermal maximum of ≥40°C was registered. The period 2000-2021 (22 years) was the warmest of all the meteorological observations in Oltenia and many annual, monthly and daily climate records were surpassed. At the same time, during the analysed interval, the melting rate of the ice in the polar areas intensified a lot and exceptional thermal maxima were registered. The heat waves during the summers were more and more intense, more frequent and longer in duration. The paper is useful to all those interested in climate variability in Oltenia.

The future of work is discussed in academic literature and reports starting with 2014. Various studies have identified artificial intelligence, robots, big data, globalization, population pressures, and changed demographic profiles as the main drivers for change in the future of jobs. Also, international organizations did comprehensive analyses of the professions' rapid technology changes. In contrast to the number of consultancy documents, there are not numerous scientific articles on the topic of the future of work. Research performed on the reputable scientific databases return a much larger number of scientific articles on the broader topic of Industry 4.0 (I4.0), including several systematic literature reviews, with 31 scientific articles on the topic. Still, the specific goal of this review is to explore the impact of job automation on the IT professions in Romania's IT industry. Consequently, the present paper is designed as a semi-systematic literature review, building on over one hundred papers written on the topic of Industry 4.0, studies that were done on the particular subject of the future of work, research papers done on the IT industry, and available studies on the IT industry in Romania. The findings are analyzed via various criteria which are meant to provide an accurate image of the state-of-the-art on the topic of interest.

Visible Light Communication (VLC) has recently emerged as an alternative to RF-based wireless communications. VLC for vehicles has demonstrated its potential for Intelligent Transportation Systems (ITSs) to exchange information between vehicles and infrastructure to achieve ITS core goals, such as improving road safety, passenger comfort, and traffic flow. This paper seeks to provide a detailed survey of vehicular VLC systems. This paper presents an overview of current developments in vehicular VLC systems and their benefits and limitations for experienced researchers and newcomers.

Currently, the management of phytopathogenic agents is an ongoing challenge globally, as they cause major damage in agricultural plantations. However, the use of synthetic pesticides currently in use has negative effects on the environment and on the living organisms that develop their life cycle in these habitats. For this reason, research in the last decade has led to the identification and exploitation of natural compounds with important antifungal properties as natural alternatives to combat and control pathogens. This review is based on the description of plant extracts, essential oils and natural compounds with important anti-fungal properties. However, their direct application to plants is difficult, because their adhesion and persistence in environmental conditions does not allow this fact. The current challenge is to develop formulations based on natural compounds that retain their properties over time in order to be applied to agricultural crops.

El desafío del cambio climático ha impulsado un cambio de paradigma en las políticas europeas. Uno de los principales pilares de actuación son las políticas de movilidad sostenible enfocadas a la reducción del uso del vehículo privado. Este artículo argumenta que los debates actuales en torno a la movilidad sostenible se centran en lo urbano, relegando a las áreas rurales a una posición secundaria o periférica. Se indaga en los límites que pueden tener las lógicas de movilidad urbana sostenible aplicadas sobre entornos rurales altamente dependientes del vehículo privado y con déficit de servicios públicos de transporte. Para ello se analizan, por un lado, las principales políticas de movilidad y transporte europeas y españolas y, por otro, los discursos y las prácticas de la población local en una ruralidad remota. Una línea de investigación que necesita ser reforzada para diseñar políticas de movilidad ajustadas a las necesidades de las poblaciones rurales.

Background The research was aimed at comparing the effect of using two types of training load different in intensity and energy supply. We studied the influence of the proposed load variations (machine and free weight exercises) on long-term adaptation of the body at the stage of specialized basic training in bodybuilding. Methods A total of 64 athletes aged 18–20 years were examined. The research participants were randomly divided into four groups, 16 athletes in each group. Athletes of group 1 and 3 used a complex of free weight exercises. Group 2 and 4 participants performed machine exercises. Bodybuilders of group 1 and 2 were trained in conditions of medium intensity training load (Ra = 0.58) in the anaerobic-glycolytic mode of energy supply. Athletes of the 3rd and 4th groups used high intensity load (Ra = 0.71) in the anaerobic-alactate mode of energy supply. We managed to determine the nature of adaptation processes using methods of control testing of strength capabilities, bioimpedansometry, anthropometry, biochemical analysis of blood serum (LDH, creatinine). Results The study showed that the difference in the dynamics of the participants’ maximum strength development (on example of chest muscles) did not depend on the content of machine or free weight exercises, but on the features of training load regimes. Thus, the controlled indicator of strength capabilities in athletes of groups 3 and 4 increased by 5.1% compared to groups 1 and 2. During all stages of the study, the indicators of the projectile working mass in athletes of groups 3 and 4 exceeded the results observed in groups 1 and 2 by 25.9%. At the same time, the amount of load in a set is on average 2 times higher in athletes of groups 1 and 2. Group 4 athletes, who used machine exercises and high intensity training load, increased the circumferential body measurements by 3.8 times (the chest), compared to the results recorded in group 1 athletes. Athletes of group 1 and 2 showed increasing in body fat by 3.4% compared to the initial level on the background of large load volume. The basal creatine level in bodybuilders of groups 3 and 4 increased by 3.7 times after 12 weeks of study, which indicates an accelerated growth of muscle mass. Conclusion The most pronounced adaptive body changes in bodybuilders at the stage of specialized basic training occurred during high intensity training load and anaerobic-alactate energy supply mode. Machine exercises contributed to increasing the morpho functional indicators of athletes more than free weight exercises.

The particularly hot summer of 2021 occurred after the third Mediterranean winter registered in Oltenia. Although the winter was warm, being the third warmest winter in descending order of the seasonal average, the spring of 2021 was cold not only in Oltenia, even in the Northern Hemisphere being considered one of the coldest springs. This weather remained until 15.VI, then on 22.VI began the first heat wave of summer 2021. During the summer of 2021 there were 6 heat waves that had several peaks. (19) with intensities frequently exceeding 38,0°C. The summer maximum temperature was 41.1°C recorded on 1.VIII.2021 in Calafat. The drought and heat wave were intense, and the total duration of the heat waves was 50 days (54.3% of summer days). The particularly hot summer of 2021 was recorded in atypical conditions with neutral Southern Oscillation (ENSO). All spring crops were severely affected. The paper analyses the climatic conditions in the summer of 2021 in Oltenia and climate variability.

For Europe, the undisputed importance of the Danube can be rendered by some general data: Its hydrographic basin surface exceeds 817000 km2, i.e. about 10% of that of the continent, its length is 2857 km and its mean multiannual discharge is about 6500 m3/s, thus ranking second to Volga river. Romania is the country with the largest surface situated within Danube’s basin (97.4%), representing 29% of Danube’s hydrographic basin. The water resources of the Danube in Bazias section amount to 173 billion m3, 30 billion m3 of which are technically usable resources.Our analysis aimed at determining those complex meteorological situations at the European continent level that triggered exceptional discharges along the Danube river, resulting in severe flooding, causing in turn heavy damages, fatalities, population evacuations and considerable rehabilitation costs. A complex analysis was performed, of statistical-synoptic type and those complex meteorological situations were identified that determined the occurrence of such disasters. Discharges and levels of the Danube were used along the whole measuring period, data from the archive of the National Meteorological Administration, and data, map and image archives from Wetterzentrale (Kartenarchiv, NCEP, NCAR, AVN etc.). The complex meteorological situations at the level of the European continent that triggered exceptional discharges along the Danube correlate with intense cyclonic activity, of both the Icelandic and the Mediterranean cyclones, with the negative phase of the North-Atlantic Oscillation and with decreasing or minimum solar activity (according to data from NOAA's Space Environment Center). The most disastrous floods occurred in the spring of 2006. The paper is important for meteorologists, in their weather forecasting activity, for hydrologists, in their hydrological forecasting and for the institutions involvedin flood management.

The circadian clock is fundamental for allowing the human body to work properly. Studies demonstrated that circadian disruption is a risk factor for a lot of pathological states and in this Review, the idea is to focus on tumorigenesis. Cancer is a social plague and it is interesting to note how the human lifestyle can be one of the most important reasons to explain the enormous spread of tumours. The crucial point described is the connection between light, melatonin and cancer genes; this triad has an important role in tumorigenesis. After that, there is a focus on breast cancer that is the most frequent in the world, and it is also demonstrated how social level and education can influence the possibility to develop cancer during life. In the end, there is a description of one of the possible new frontiers in the treatment of cancer: chronotherapy.

The purpose of our work is to highlight the warm character of winter 2019-2020, from the perspective of the spatial area of the Bâc river basin. The data regarding the temperature for the winter months (2019- 2020) were extracted from the official website of the State Hydrometeorological Service. In order to determine the thermal characteristics, the daily temperatures of December (2019), January and February (2020) were analyzed from the four basin weather stations. The average air temperature for the winter season 2019-2020 constituted in the basin +1.6 - +3.3°С, being 4.3 - 5.4°С higher than the multiannual average and is reported for the first time during the entire observation period. According to the data of the Chişinău weather station (125 years observation period), the average air temperature for the winter 2019-2020 was +3.1°С (5.2°С higher than the norm) and placed on the 1st place in the range of years with high average temperatures for the respective season. In December 2019, the maximum air temperature rose in the basin to +18°С (December 18, Codrii Meteorological Station, Strășeni district), which in this decade is reported on average every 30 years. Very hot weather was reported in January and February (2020). Analogous winter after the thermal regime was 2006-07.

The goal of this study had as a premise a perceived gap of knowledge regarding the use of digital media and platforms by Romanian organizations with the purpose to disclose corporate social responsibility (CSR) information. In the context of the ever-increasing digitalization process, the research aimed to explore the current situation within the organizational setting to provide evidence on the type of media and content used and with a view to identifying possible trends. To objectively assess the situation, the study employed models developed by various researchers to measure CSR disclosure on corporate websites, Facebook and Twitter accounts. The results of the study indicate that the selected Romanian companies make limited use of online media for the purpose to reveal CSR. They rather prefer corporate websites and Facebook accounts to communicate such information to stakeholders, while Twitter is rarely utilized. The findings point to the fact that education and social development are the areas of CSR where Romanian companies mostly contribute, but, at the same time, they signal that the advantages and advances availed by systemic digitalization are yet to be properly exploited against the backdrop of CSR disclosure.

In the present article, we consider submanifolds in golden Riemannian manifolds with constant golden sectional curvature. On such submanifolds, we prove geometric inequalities for the Casorati curvatures. The submanifolds meeting the equality cases are also described.

The oil and gas sector is important to the global economy because it covers the exploration, production, processing, transportation, and distribution of oil and natural gas resources. Despite constant innovation and development of technologies to improve efficiency, reduce environmental impact, and optimize operations in the gas and oil industry over the last few decades, there is still room to increase the efficiency of the industry’s equipment in order to reduce its carbon footprint. The separation of gas from oil is a critical stage in the technological production chain, and it is carried out using high-performance multi-phase separators to limit greenhouse gas emissions and have a low impact on the environment. In this study, an improved gas–oil separator configuration was established utilizing CFD techniques. Two separator geometry characteristics were studied. Both cases have the same number of subdomains, two porous media, and four fluid zones, but with a difference in the pitch of the cyclone from the inlet subdomain. The streamlines in a cross-plan of the separator and the distribution of the oil volume fraction from the intake to the outlet were two of the numerical results that were shown as numeric outcomes. The validation of these results was performed using an experimental testing campaign that had the purpose of determining the amount of lubricating oil that is discharged together with the compressed gas at the separator outlet.

In this paper, we address the study of the Kobayashi–Nomizu type and the Yano type connections on the tangent bundle TM equipped with the Sasaki metric. Then, we determine the curvature tensors of these connections. Moreover, we find conditions under which these connections are torsion-free, Codazzi, and statistical structures, respectively, with respect to the Sasaki metric. Finally, we introduce the mutual curvature tensor on a manifold. We investigate some of its properties; furthermore, we study mutual curvature tensors on a manifold equipped with the Kobayashi–Nomizu type and the Yano type connections.

Clinical problem solving evolves in parallel with advances in technology and discoveries in the medical field. However, it always reverts to basic cognitive processes involved in critical thinking, such as hypothetical–deductive reasoning, pattern recognition, and compilation models. When dealing with cases of acute abdominal pain, clinicians should employ all available tools that allow them to rapidly refine their analysis for a definitive diagnosis. Therefore, we propose a standardized method for the quick assessment of abdominopelvic computed tomography as a supplement to the traditional clinical reasoning process. This narrative review explores the cognitive basis of errors in reading imaging. It explains the practical use of attenuation values, contrast phases, and windowing for non-radiologists and details a multistep protocol for finding radiological cues during CT reading and interpretation. This systematic approach describes the salient features and technical tools needed to ascertain the causality between clinical patterns and abdominopelvic changes visible on CT scans from a surgeon’s perspective. It comprises 16 sections that should be read successively and that cover the entire abdominopelvic region. Each section details specific radiological signs and provides clear explanations for targeted searches, as well as anatomical and technical hints. Reliance on imaging in clinical problem solving does not make a decision dichotomous nor does it guarantee success in diagnostic endeavors. However, it contributes exact information for supporting the clinical assessments even in the most subtle and intricate conditions.

The incidence of common bile duct injuries following laparoscopic cholecystectomy (LC) remains three times higher than that following open surgery despite numerous attempts to decrease intraoperative incidents by employing better training, superior surgical instruments, imaging techniques, or strategic concepts. This paper is a narrative review which discusses from a contextual point of view the need to standardise the surgical approach in difficult laparoscopic cholecystectomies, the main strategic operative concepts and techniques, complementary visualisation aids for the delineation of anatomical landmarks, and the importance of cognitive maps and algorithms in performing safer LC. Extensive research was carried out in the PubMed, Web of Science, and Elsevier databases using the terms ”difficult cholecystectomy”, ”bile duct injuries”, ”safe cholecystectomy”, and ”laparoscopy in acute cholecystitis”. The key content and findings of this research suggest there is high intersocietal variation in approaching and performing LC, in the use of visualisation aids, and in the application of safety concepts. Limited papers offer guidelines based on robust data and a timid recognition of the human factors and ergonomic concepts in improving the outcomes associated with difficult cholecystectomies. This paper highlights the most relevant recommendations for dealing with difficult laparoscopic cholecystectomies.

Aproximativ una din două femei prezintă simptome de existență a unei formațiuni la nivelul sânilor. Conform diferitor date, frecvența depistării patologiilor benigne a glandei mamare este mult mai sporită comparativ cu frecvența adresării femeilor la medic cu aceste patologii. Tumorile benigne ale glandei mamare se caracterizează printr-o creșterea lentă, expansivă (comprimă țesutul vecin), sunt bine incapsulate, majoritatea sunt rezultatul unor modificări hormonale (hiperestrogenemia, hiperprolactinemia), după excizie recidivează rar, nu invadează țesuturile locale și nu metastează în alte organe. Tratamentul de bază este chirurgical – excizia formațiunilor din sân. Recidivele apar rar, nu invadează țesuturile adiacente și nu metastează în alte organe [6, 8, 9]
