During the summer of 2022 Rudbeckia triloba L. was recorded outside cultivation at four localities in the inland part of Croatia (Korana Selo, Vukova Gorica, Vugrovec and Slivonja Jarek) growing in anthropogenic habitats. This species, native to North America, was introduced to Europe as an ornamental and in several European countries is spreading mostly as garden escapee. The time of introduction into Croatia is not known. It can be considered a casual alien or a garden escapee ephemerophyte with an as yet unknown invasive potential.

Authors: Morakinyo Barnabas O , Lavender Samantha , Abbott Victor
Published: January 2023

Detection of potentially gas flaring-related pollution on vegetation cover using remotely sensed data at 11 flaring sites in Rivers State, Nigeria is the emphasis of this research. 21 Landsat 7 Enhanced Thematic Mapper Plus (ETM ), and 4 Landsat 8 Operational Land Imager and Thermal Infrared Sensor (OLI-TIRS) data dated from 21/04/2000 to 05/02/2022 with  3  cloud cover were used. Normalized Differential Vegetation Index (NDVI) was retrieved from corrected Landsat 7 bands (1-4), and Landsat 8 bands (2-5). Corrected thermal band was used for the computation of Land Surface Temperature (LST). Change in NDVI (δNDVI450-60)m and LST ( δLST60-450m) were computed. NDVI values at 60 m from the stack show that as the year increases, NDVI values around the stack reduces to almost zero. Linear regression analysis was considered for (δ NDVI450-60)mN against ( δNDVI450-60)mE, (δNDVI450-60)mN against (δNDVI450-60)mS, and (δNDVI450-60)mN against (δNDVI450-60)mW. Only (δNDVI450-60)mN against (δNDVI450-60)mW give statistically significant results at 99 % confidence level (p-value  0.0016). (δNDVI450-60)mN,E,S,W against (δLST60-450)mN,E,S,W were considered and results show positive correlation but statistically insignificant. Based on the results of this research, it can be concluded that flaring-related pollution can be detected on vegetation cover using Landsat 7 and Landsat 8 data in the Niger Delta.
Environmentally friendly strategy for hybrid flow shop scheduling with the unrelated parallel machines
Authors: Kong Lin , Li Fangyi , Wang Liming , Li Jianfeng , Wang Yitong , Cai Zekang , Zhou Jiaxuan
Published: January 2023

With the increasing environmental pressure, reducing the environmental impact on hybrid flow shops (HFS) has attracted extensive attention because of its broad industrial applications. The selection of machines in the implementation of HFS is a complex decision-making process that hinders the optimization efficiency in shops. However, this issue has not been addressed thoroughly. In light of this, a multi-objective mathematical model is formulated for the minimization of makespan and energy consumption of the hybrid flow shop scheduling problem (HFSP). The environmental performance of machines is calculated by the proposed evaluation index and is ranked on the basis of the integrated entropy and fuzzy technique for order performance by similarity to ideal solution method. Moreover, to solve the multi-objective model of HFSP, an improved differential evolution algorithm with a heuristic active decoding rule that incorporates the ranking of environmental performance of machines into the iterative process of the algorithm is presented. Finally, a case study is presented to evaluate the effectiveness of the proposed method and to prove the feasibility of the ranking-based differential evolution algorithm (RBDE). The result shows that the proposed RBDE outperforms RBNSGA-II and RBPSO in searching for non-dominated solutions that can solve the environmental production of HFSP effectively.
Learning to switch gears — Steering palliative care into emergency medicine
Authors: Bhat Rachana , Ramaswami Akshaya , Aggarwal Praveen
Published: January 2023

Emergency care is largely seen as synonymous with resuscitation and saving lives. In most of the developing world where Emergency Medicine (EM) is still evolving, the concept of EM palliative care is alien. Provision of palliative care in such settings poses its own challenges in terms of knowledge gaps, socio-cultural barriers, dismal doctor-to-patient ratio with limited time for communication with patients, and lack of established pathways to provide EM palliative care. Integrating the concept of palliative medicine is crucial for expanding the dimension of holistic, value-based, quality emergency care. However, glitches in decision-making processes, especially in high patient volume settings, may lead to inequalities in care provision, based on socio-financial disparities of patients or premature termination of challenging resuscitations. Pertinent, robust, validated screening tools and guides may assist physicians in tackling this ethical dilemma.
Western Vector of Greece's Foreign Policy (Late 2010s – Early 2020s)
Authors: Kvashnin Y.
Published: January 2023

One of the main features of Greek diplomacy is the combination of pro-Western orientation and the desire to act independently in a number of key issues, firmly defending national interests. In recent years, however, the western vector began to prevail. In ideology, this manifested itself in the positioning of the country as an outpost of Western civilization in the East, a defender of democratic values, operating in accordance with the interests of collective West. In security policy, the main efforts were aimed at creating a counterbalance to Greece's existential rival – Turkey. Not having sufficient resources for an ‘arms race’ with the eastern neighbour, the Greek authorities have shifted their focus to closer cooperation with major powers, as well as with regional actors seeking to curb Turkish ambitions. The idea of confronting ‘geopolitical revisionism’ has taken a prominent place in the political rhetoric of the conservative government, especially since the start of the Russian special military operation in Ukraine. In economic sphere, Greece continues its policy aimed at becoming a key transit hub for transporting energy resources to Europe. Despite the fact that there are good reasons for strengthening ties with the West, the ultimate success of this strategy is not evident. In the Greek media, there is an increasing opinion that such a course will narrow the room for diplomatic maneuver. At the same time, the main task – to isolate Turkey – will not be implemented. In the future, imbalances in foreign policy may hinder the development of economic ties between Greece and non-Western countries (in the case of Russian-Greek relations, this is already happening), and this in turn will undermine the country's resilience to crisis processes in the world economy and politics.
Balkan Countries’ Approach to Cooperation with Russia
Authors: Kandel P.
Published: January 2023

The article examines three parameters of the stated subject: policies of the state governments of South-Eastern Europe in the light of the new developments in Ukraine, widespread attitudes and the configuration of political forces in these countries which may provide a chance to pro-Russian circles. The analysis is based on both national and international opinion polls and the results of the latest elections. As is shown, the traditionally strong Russophile sentiments in many countries of the region have reverberated again and affected the perception of the conflict. It's only natural for Russia’s public opinion, focused on events in and around Ukraine, to look at everything through the lens of Russia opposing the collective West. However, in a region, where the European Union for every single state is a pole of centripetal tendencies and where a NATO membership is a much needed permit to that pole, people view things in a different way. Thus, projecting Russian worldview on local reality is methodologically flawed and it would lead to incorrect assessments and conclusions. Pro-Russian sympathies made themselves known in areas where there are such. However, the potential of the pro-Russian forces is insufficient for a fundamental change in policies although the ruling circles cannot completely ignore it. The article concludes that the status and prospects of Russian cooperation with the countries of the region will remain unfavorable until the end of military operation in Ukraine, although the EU and the USA are unlikely to succeed in achieving complete abandonment of Russian energy resources in a short time.

This grouping allows you to see how key characteristics of enterprises differ depending on how their production capacities are loaded and what level of debts to banks they have. Data are presented for the first quarter of 2022.
Storage of Biochemical Information as the Start of Life: A Hypothetical Model for the Development of the First Cell
Authors: Schreiber Ulrich
Published: January 2023

The storage of biochemical information, which is a prerequisite for the development of the first cell, is an unsolved problem affecting all concepts of the origin of life. However, if the protected environment in the continental crust is taken into account, completely new possibilities emerge for identifying processes that may have been crucial for the formation of the first cell. Under this background, we can hypothesize that cellular life began, with a self-sustaining cycle of molecular reaction steps and information storage of peptide sequences in RNA in a crustal depth of approximately 1000 m. This cycle was made possible in an open system bound to gas-permeable tectonic fracture zones with a high proportion of CO2 and/or N2. It can be assumed that a large number of RNA-like molecular strands formed in the crustal environment, from which a special RNA was selected by flotation processes, which formed the basis of a proto-tRNA. The formation of peptides and vesicles in supercritical CO2 and the chemical evolution of peptides have already been proven at conditions of the upper continental crust. The behavior of individual amino acids in connection with vesicle formation deserves special interest. Hydrophobic amino acids accumulate in the vesicle membrane, with their position in the membrane depending on the degree of hydrophobicity. Selection of a proto-tRNA with an acceptor arm ending with the bases CCA resulted in a distinctive property. The position of adenine at the tip of the acceptor arm permitted it to penetrate the membrane, allowing it to be linked to an amino acid at the 3'-OH position of the terminal ribose. The penetration depth was controlled by the hydrophobicity of the opposite anti-codon, with adenine always occupying the middle position for the hydrothermally formed hydrophobic amino acids. When the vesicle membrane was closely occupied by proto-tRNAs, the anti-codons acted as templates and stored the sequence of the peptides that form. In the cases of hydrophilic anti-codons, the acceptor arm does not reach far enough into the membrane. This allowed hydrophilic amino acids to be linked to 2´-OH.

The COVID-19 disease has infected many countries with generalised impacts on the different income categories. To test this hypothesis, we carried out a survey among households (n = 412) representing different income groups in Nigeria. We used validated food insecurity experience and socio-psychologic tools. We analysed the data obtained using descriptive and inferential statistics. The earning capacities of the respondents range from US$145/month for the low-income earners to US$1945/month for high-income earners. A total of 173 households (42%) ran out of food during the COVID-19 pandemic. All categories of households have experienced increasing dependency from the general public and perception of increasing insecurity, with the high-income earners having the greatest shift. In addition, increasing levels of anger and irritations have been experienced with all categories. Of the socio-demographic variables, only gender (p = 0.012), level of education of household head (p = 0.000), work hours per day (p = 0.006), and family income based on society class (p = 0.000) were significantly associated with food security and hunger due to the COVID-19 pandemic. Household heads with medium (OR: 4.36, 95% CI: 2.64 – 7.21, p < 0.001) and high (OR: 30.27, 95% CI: 3.99 – 229.90, p < 0.001) family income based on society class were more likely to have satisfactory experience on food security and hunger than respondents with low family income. Irrespective of the social class of the respondents, some respondents had negative experiences such as movement/change of location within the same city (17.68%), begin a new relationship (14.43%), recent change of job/loss of job (11.55%), movement to another city (10.81%), and separation from spouse or long-term relationship (10.07%). However, 231 (60.16%) reported satisfaction with their jobs despite the pandemic. Psychological stress due to impact of COVID-19 was observed to be more in the low income earning group than others. It is recommended that socio-economic groups should be mapped and support systems should target each group as per the needed support in terms of health, social, economic, and mental wellness; the government should show political commitments and transparency in food security and counselling supports. National authorities should prioritize empirical-based interventions on resources allocation during crises.

The covid-19 pandemic has generated substantial changes in the lives of the population, such as increased physical inactivity, which can lead to overweight and, consequently, repercussions on glucose homeostasis. A population-based household epidemiological survey was conducted by stratified, multistage probability cluster sampling (October and December 2020) in Brazil. Participants were classified as physically active or inactive during leisure time according to the recommendations of the World Health Organization. HbA1c levels were categorized as normal (≤6.4%) or with glycemic changes (≥ 6.5%). The mediating variable was excess weight (overweight and obese). Multivariate logistic regression analyzes were performed to examine the association between physical inactivity and glycemic changes. Mediation was analyzed using the Karlson–Holm–Breen method to verify the influence of excess weight on the association. We interviewed 1,685 individuals, mostly women (52.4%), 35–59 years old (45.8%), race/ethnicity brown (48.1%), and excess weight (56.5%). The mean HbA1c was 5.68% (95% CI: 5.58-5.77). Individuals physically inactive were 2.62 times more likely to have glycemic alterations (OR:2.62.95% CI:1.29-5.33), and 26.87% of this association was mediated by excess weight (OR:1.30:95% CI:1.06-1.57). Physical inactivity in leisure time increases the chances of glycemic alterations, and part of this association can be explained by excess weight.
Effects of Different Guests on Pyrolysis Mechanism of Α-CL-20/Guest at High Temperatures by Reactive Molecular Dynamics Simulations at High Temperatures
Authors: Zhou Mingming , Luo Jing , Xiang Dong
Published: January 2023

The host-guest inclusion strategy has potential to surpass the limitations of energy density and suboptimal performances of single explosives. The guest molecules can not only enhance the detonation performance of host explosives but can also enhance their stability. Therefore, the deeply analysis the role of guest influence on the pyrolysis decomposition of the host-guest explosive is necessary. The whole decomposition reaction stage of CL-20/H2O, CL-20/CO2, CL-20/N2O, CL-20/NH2OH was calculated by ReaxFF-MD. The incorporation of CO2, N2O and NH2OH significantly increase the energy levels of CL-20. However, different guest has little influence on the initial decomposition paths of CL-20. The Ea1 and Ea2 values of CL-20/CO2, CL-20/N2O, CL-20/NH2OH systems are higher than the CL-20/H2O system. Clearly, incorporation of CO2, N2O, NH2OH can inhibit the initial decomposition and intermediate decomposition stage of CL-20/H2O. Guest molecules get heavily involved in the reaction and influence on the reaction rate. k1 of CL-20/N2O and CL-20/NH2OH systems are significantly larger than that of CL-20/H2O at high temperatures. k1 of CL-20/CO2 system is much complex, which can be affected deeply by temperatures. k2 of CL-20/CO2, CL-20/N2O system is significantly smaller than that of CL-20/H2O at high temperatures. k2 of CL-20/NH2OH system is little difference at high temperatures. For the CL-20/CO2 system, the k3 value of CO2 is slight higher than that for CL-20/H2O, CL-20/N2O, CL-20/NH2OH systems, while the k3 values of N2 and H2O are slight smaller than that for CL-20/H2O, CL-20/N2O, CL-20/NH2OH systems. For the CL-20/N2O system, the k3 value of CO2 is slight smaller than that for CL-20/H2O, CL-20/CO2, CL-20/NH2OH systems. For the CL-20/NH2OH system, the k3 value of H2O is slight larger than that for CL-20/H2O, CL-20/CO2, CL-20/N2O systems. These mechanisms revealed that CO2, N2O and NH2OH molecules inhibit the early stages of the initial decomposition of CL-20, and play an important role for the decomposition subsequently.

The regular menstrual cycle is one of the key health indicators in women of reproductive age, while its disorders most often demonstrate the presence of ovarian dysfunction (OD). Women with OD are at risk of infertility, adverse pregnancy outcomes, carbohydrate metabolism disorders, cardiovascular diseases, osteoporosis, and oncopathology. The aim of this review was to systematize the current data on the prevalence, clinical forms, and methods of diagnosis of OD. OD is very common in the female population, has a complex etiopathogenesis, is one of the symptoms of serious endocrinopathies, genetic disorders, and is a frequent cause of infertility. The main types of OD are oligo/anovulation (OA) and luteal phase deficiency (LPD). Depending on the nature of hormonal disorders, hypogonadotropic, normogonadotropic, hypergonadotropic OD and OD against the background of hyperprolactinemia are distinguished. Clinical manifestations of OD include oligo/amenorrhea, abnormal uterine bleeding and may have a subclinical course without menstrual irregularities. The diagnosis of OD is a challenging task that requires a thorough collection of menstrual history, determination of serum progesterone levels in the luteal phase, evaluation of instrumental examination results. Differential diagnosis of OD is necessary for detecting the clinical form of OD and should be based on the use of modern clinical protocols and standardized algorithms. Key words: ovarian dysfunction, oligo/anovulation, oligo/amenorrhea, menstrual disorders, luteal phase deficiency

SHIPPING FUEL PRODUCED FROM SECONDARY POLYMER RAW MATERIALS
Authors: Chernyavsky A. , Grigorov A.
Published: January 2023

The article considers the possibility of expanding the raw material base of the production of motor fuels, particularly the fuels for shipping due to the use of secondary polymer raw materials. It was established that this raw material, which is represented by various polyolefins, is characterized by the absence or rather low (up to 150–200 ppm) content of sulfur-containing compounds.

Therefore, according to such an indicator as the sulfur content, using thermal or catalytic pyrolysis technologies in a reactor-type apparatus, it is possible to obtain fuels from secondary polymer raw materials, which in terms of sulfur content (0.5 % and 0.1 %, respectively) will correspond to marine gasoil (MGO) or low sulfur marine gasoil (LS-MGO).

It was experimentally established that the products of thermal pyrolysis of secondary polymer raw materials contain up to 30–40 % of olefinic hydrocarbons, which have low chemical stability and increased hygroscopicity compared to paraffinic and naphthenic hydrocarbons. Given their properties, such products should only be used as components of marine fuels. The products of catalytic pyrolysis (the process was carried out using the ZSM-5 zeolite catalyst) of secondary polymer raw materials, on the contrary, have high chemical stability due to the low (up to 3 %) content of olefinic hydrocarbons. But, at the same time, they contain up to 15 % aromatic hydrocarbons in their composition, which does not exceed the generally accepted restrictions on their content in motor fuels.

It has been determined that the initial boiling point of the obtained fractions is the main parameter, which can be used to regulate some quality indicators of the products obtained. Its increase significantly reduces hygroscopicity and increases the flash point of the obtained products. However, it is not advisable to significantly increase this indicator, given the decrease in the yield of the target product (increasing the boiling point of the fraction by only 1 °C leads to a decrease in its yield by 0.275–0.325 %).

Published: January 2023

The article examines the issues of students' research work, components and functions of research work. The types and forms of research work in academic and extracurricular time are distinguished.

Of particular practical importance is the specialist's ability to adequately perceive complex life situations, correctly assess them, quickly adapt to new cognitive situations, purposefully process available information, search for and supplement the missing information, know the patterns of its optimal use, predict the results of activities, using one's intellectual and creative potential .

At each level of education, it is necessary to develop students' creative thinking and research skills, without which it is difficult both to continue their education and to be realized in the labor market.

In this connection, scientific research activity is gaining more and more importance and is turning into one of the main components of the professional training of the future specialist.

Scientific and research activity improves not only the professional level, but also forms specific skills and habits, the appropriate composition of thinking and communication. In connection with the new requirements for the quality of the training of specialists, meeting the needs of the accelerated scientific, technical and socio-economic development of the country, the scientific and research activity of students is considered as an important factor in improving the entire system of training specialists for various branches of the national economy. It is scientific and research activity that allows deepening the professional direction of education, educating specialists with high creative potential and influences the formation of social and professional maturity of future specialists.

Thus, in order to successfully manage the research work of students, the dynamics of its constituent elements, the teacher must clearly imagine its main tasks: which research object to choose and which research methods to apply. Therefore, the strategic task in this direction is to foresee the following conditions, means: forms and content of activities, which are the most favorable and optimal for the development and improvement of scientific research work.

Accordingly, scientific and research activities should be organized so that students, after graduating from the educational institution, strive for constant improvement of their professional level. A person must constantly learn, correlating his knowledge with new requirements, his needs, the needs of society, the labor market. The personality itself is its professional toolkit.
A SOFTWARE TOOL FOR QUALITY MEASUREMENT OF BUSINESS PROCESS MODELS USING DISTANCES IN N-DIMENSIONAL SPACE
Authors: Kopp Andrii , Orlovskyi Dmytro
Published: January 2023

This paper considers the problem of quality measurement of business process models using the n-dimensional space distances. Business process models are graphical schemes similar to flowcharts or activity diagrams utilized in software engineering, usually represented using the BPMN (Business Process Model and Notation) or EPC (Event-driven Process Chain) notations. Business process modeling aims to capture current enterprise workflows for their analysis and then improvement using automation through IT (Information Technology) systems deployment. Therefore, designed business process models should be of high quality, so all “weak spots” of described organizational workflows could be properly identified and replaced with more efficient solutions. Whereas process models, which are not understandable, un-structured, and/or uncertain, may cause even more issues when used to improve organizational activities. Therefore, this study proposes quality measures and a software tool that can be used to detect errors in BPMN and EPC business process models using distances in n-dimensional space. The formal problem statement based on the graph-based description of business process models was given. Business process model quality characteristics and measures that consider features of both BPMN and EPC notations were proposed. Distances in n-dimensional space were suggested for usage to measure the quality of business process models. The algorithm for business process model quality measurement was proposed. The software tool to measure the quality of BPMN and EPC business process models was designed and developed. The quality of sample business process models was measured using the software tool. Obtained results were analyzed and discussed. This paper considers the Euclidean distance only, while other existing n-dimensional space distance measures or, on the opposite, similarity measures, can be used to evaluate business process model quality in further research.
AN EXPLANATION MODEL IN AN INTELLIGENT SYSTEM AT THE LOCAL, GROUP AND GLOBAL LEVELS OF DETAIL
Authors: Chalyi Serhii , Leshchynskyi Volodymyr
Published: January 2023

The subject of research is the process of formation of explanations in intellectual information systems. Machine learning methods are used in modern intelligent systems. The process of obtaining the solution formed on the basis of such methods is usually opaque to the user. As a result of such opacity, the user may not trust the solutions proposed by the intelligent system. This reduces the efficiency of its use. Explanations are used to increase the transparency of decisions. The explanation is represented by knowledge about the reasons for the formation of the result in the intellectual system, as well as about the reasons for individual actions in the process of formation of the result. Also, the explanation may contain knowledge about the influence of individual functions on the results obtained by the intelligent system. Therefore, it is advisable to form an explanation at different levels of detail in order to show both the generalized reasons and effects on the obtained decision, as well as the reasons for choosing individual intermediate actions. The purpose of the work is to develop a generalized model of explanation considering the states of the decision-making process in an intelligent system to build explanations based on known data regarding the sequence of states and the properties of these states. To achieve the goal, the following tasks are solved: structuring the properties of explanations; determining the possibilities of approaches to building explanations based on the states and structure of the decision-making process, as well as on the basis of input data; construction of an explanatory model. Conclusions. A generalized model of explanation in an intelligent system for local, group and global levels of detail of the decision-making process is proposed. The model is represented by an ordered sequence of weighted dependencies between events or states of the decision-making process. The model is focused on presenting the possibility to highlight a local explanation within the framework of a global explanation and to present a chain of group explanations between the events of obtaining input data and the resulting decision. In practical terms, the proposed model is intended for the construction of explanations using approaches based on the simplification of the process of functioning of the intelligent system and on the basis of highlighting the influence of individual functions and actions on the final result. Additional capabilities of the model are related to the detailing of the events of the decision-making process from the selection of individual variables that characterize the state of this process, which makes it possible to form an explanation based on the use of known concepts and concepts in the subject area.
Incapaz de gobernarse a sí misma: Roma de HBO

Published: January 2023

Creada por John Milius y William J. MacDonald, Roma (2005-2007) supuso un punto de inflexión para las series históricas en televisión. Coincidiendo con el auge de los canales por cable, HBO buscó primar un producto que tratase temas de contenido más adulto, apostando por una recreación de la gran urbe tardorrepublicana durante el pulso de poder entre Julio César y Cneo Pompeyo. Usando a los dos únicos legionarios citados en los famosos Comentarios cesarianos sobre la conquista de las Galias, Tito Pullo y Lucio Voreno, el programa rodado en los célebres estudios de Cinecittà busca hacer una radiografía de todos los elementos que vertebraban al mundo antiguo (esclavos, comerciantes, senadores, patricias, centuriones, mujeres del pueblo, criminales, etc.). Nuestro análisis busca centrarse en las posibilidades de aprendizaje que nos brindan las dos temporadas del show, destacando un contraste entre la ficción y los datos de las fuentes clásicas, además de los recientes avances en la investigación de dicho periodo histórico.

Authors: Míguez Santa Cruz Antonio
Published: January 2023

Desde los albores del s. XXI las series televisivas de temática histórica no han hecho más que ganar adeptos entre el gran público. En la actualidad, el fenómeno alcanza dimensiones colosales apoyándose en el streaming, pues se han diversificado los espacios y épocas representadas, al tiempo que se consiguen atmósferas mucho más verosímiles. Paralelamente vivimos en los tiempos del mass media, cuando las redes sociales y la multipantalla son ya indisolubles del contexto diario dentro de cualquier aula. La acción y la adaptabilidad crean oportunidades, dijo el actor protagonista de Twin Peaks, Kyle Maclachlan sobre su relación con David Lynch, y de igual modo pienso que el contexto digital puede y debe ser aprovechado según la sensibilidad del actual alumnado. Por tanto, nuestro objetivo en este monográfico será analizar distintos shows de inspiración histórica –ya sea de manera directa o indirecta– en su plano narrativo y técnico, aunque sobre todo hemos incidido sobre sus múltiples utilidades en el ámbito de la docencia innovadora.

Published: January 2023

A methodology for simulating groundwater flow in three-dimensional (3D) stochastic fracture rocks based on a commonly used finite-difference method is presented in this paper. Different realizations of fracture networks are generated by the fracture continuum method (FCM), in which appropriate 3D cuboids are used to describe the geometry of fractures. Then, the effects of different parameter distributions on the fracture networks indicated that the length, orientation, and density of fractures all play significant roles in the connectivity of fractures in this methodology. Greater length and density and wider orientation range of fractures lead to greater connectivity. The proper contrast in hydraulic conductivities between the fractures and matrix is found to be approximately 105 due to the contribution of fluid flow in the matrix which can be ignored. It is shown that the fracture density plays a key role in stabilizing the equivalent hydraulic conductivity (Ke) of the fracture networks. Furthermore, the greater length and closer orientation of fractures to the general flow direction, the larger Ke of the generated fracture networks possess. The findings of this study can help for a better understanding of the mechanism of FCM and the influence of geometry characteristics on the hydraulic conductivity of FCM models.

Purpose
The aim of this study was to determine the age- and sex-specific incidence and prevalence of keratoconus (KC) in Taiwan and explore their association with computerized corneal topography use.
Design:
This nationwide population-based retrospective study included the data of the Taiwanese population (N = 27,540,859) from the National Health Insurance Research Database (NHIRD) from 2000 to 2018.
Method
We estimated the incidence of KC by identifying patients with newly diagnosed KC and estimated its prevalence by identifying the total number of patients who had the ICD-9-CM code 371.6 or ICD-10-CM code H18.609 twice or more in NHIRD during 2000–2018.
Results
The incidence of KC in Taiwan during 2000–2018 was 7,075, with the incidence rate being 1.56 (95% confidence interval [CI]: 1.53–1.60) per 100,000 person-years. The prevalence of KC was 4.29 (95% CI: 4.23–4.35) per 100,000 person-years. The KC incidence rate peaked in patients aged 21–25 years (6.40 in male patients and 3.19 in female patients). The overall incidence rates in male and female patients were 2.01 and 1.35, respectively (incidence rate ratio: 1.46), indicating that KC had a significant male predisposition. Moreover, we noted a linear correlation (R2 = 0.7488) between the proportion of computerized corneal topography use and the incidence of KC in our study.
Conclusion
Estimates of nationwide population-based incidence and prevalence can contribute to better understanding of the risk of ethnic groups and geographic locations in the pathophysiology of KC, and the trend can help physicians improve the general vision health of the population.

What happens in the human brain when we are unconscious? Despite substantial work, we are still unsure which brain regions are involved and how they are impacted when consciousness is disrupted. Using intracranial recordings and direct electrical stimulation, we mapped global, network, and regional involvement during wake vs. arousable unconsciousness (sleep) vs. non-arousable unconsciousness (propofol-induced general anesthesia). Information integration and complex processing were reduced, while variability increased in any type of unconscious state. These changes were more pronounced during anesthesia than sleep. They also involved different cortical engagement; During sleep, changes were mostly uniformly distributed across the brain while during anesthesia the prefrontal cortex was the most disrupted, suggesting that the obliteration of consciousness during anesthesia results not from just altered overall physiology but from a disconnection between prefrontal and other brain areas. These findings provide direct evidence of the different neural signatures for different types of unconsciousness.
Sea ice, argon and carbon dioxide
Authors: Hambler Clive
Published: January 2023

1) Atmospheric argon on Earth and Mars cycles on a seasonal basis and abiotic factors will be particularly important drivers of this noble gas.
2) It is predicted and confirmed that there is similarity in the seasonality of sea ice and argon, with atmospheric argon in a Hemisphere often increasing fastest when sea ice in that Hemisphere is declining fastest.
3) There is some visual similarity between the detailed phenology of Greenland Sea ice extent and argon in some Northern Hemisphere sites, but formal analysis is required.
4) Argon monthly rates of change are inversely correlated with those of Antarctic sea ice and carbon dioxide for at least one Southern Hemisphere site (Palmer Station).
5) If causal, the mechanism is unclear but could involve argon bubble formation during freezing and bubble release in the spring melt.
6) Other variables with very similar phenology to sea ice, including high-latitude sea temperatures, should be investigated as potential drivers.
7) Cycling of argon by sea ice would strengthen the argument that seasonal cycling of carbon dioxide is in part driven abiotically, and also necessitate revision of oxygen flux estimates.
8) The general absence of lags between argon and carbon dioxide cycles suggests the dominant seasonal fluxes of both gases are in high latitudes and marine.
9) Failure to explore the causality of the highly similar time-series of argon, oxygen, methane and carbon dioxide could be extremely costly and scientifically remarkable.

The current production and conception have impacted the environmental hazards. Green Innovation (GI) is the ideal solution for sustainable production, consumption, and ecological conservation. The objective of the study is to compare comprehensive green innovation (covering product, process, service & organization) impact on firm financial performance in Malaysia and Indonesia, along with the first study to measure the moderation role of the corporate governance index. This study has addressed the gap by developing the green innovation and corporate governance index. Collected panel data from the top 188 publicly listed firms for three years and analyzed it using the General Least Square (GLS) method. The empirical evidence demonstrates that the green innovation practice is better in Malaysia, and the outcome also shows that the significance level is higher than in Indonesia. In addition, this study provides empirical evidence that board composition has a positive moderation relationship betwixt GI and business performance in Malaysia but is insignificant in Indonesia. This comparative study provides new insights to the policymakers and practitioners of both countries.

Background: Oesophageal cancer (EC) is the sixth leading cause of cancer death worldwide. Oesophageal resection is the only curative treatment option for EC which is frequently performed via an abdominal and right thoracic approach (Ivor-Lewis operation). This 2-cavity operation is associated with a high risk of major complications. To reduce postoperative morbidity several minimally invasive techniques have been developed, that can be broadly classified into either hybrid esophagectomy (HYBRID-E) via laparoscopic/robotic abdominal and open thoracic surgery or total minimally invasive esophagectomy (MIN-E). Both, HYBIRD-E and MIN-E, compare favourable to open esophagectomy. However, there is still an evidence gap comparing HYBRID-E with MIN-E with regard to postoperative morbidity.
Methods: The MICkey trial is a multicentre randomized controlled superiority trial with two parallel study groups. A total of 152 patients with oesophageal cancer scheduled for elective esophagectomy will be randomly assigned 1:1 to the control group (HYBRID-E) or to the intervention group (MIN-E). The primary endpoint will be overall postoperative morbidity assessed via the comprehensive complication index (CCI) within 30 days after surgery. Specific perioperative parameters, as well as patient-reported and oncological outcomes, will be analysed as secondary outcomes.
Discussion: The MICkey trial will address the yet unanswered question whether the total minimally invasive esophagectomy (MIN-E) is superior to HYBRID-E procedure regarding overall postoperative morbidity.

Mars’s crustal and volcanic structure explained by southern giant impact and resulting mantle depletion

Published: January 2023

Mars features a crustal dichotomy, with its southern hemisphere covered by a thicker basaltic crust than its northern hemisphere[1,2]. Additionally, the planet displays geologically recent volcanism only in its low latitude regions[3-5]. Previous giant impact models coupled with simulations of mantle convection have shown that the crustal dichotomy can be explained by post-impact melt crystallization that emplaced a thick crust in the southern hemisphere[6-8]. In this study, we show that the depleted residue left behind by the original post-impact crustal formation can spread laterally, potentially persisting beneath the northern hemisphere to the present day. Such a large-scale mantle province would concurrently explain both the prevalence of long-term magmatism on Mars and its strong preference for localised equatorial regions.
