Politeness Strategies in Email Opening and Closing Moves by Saudi Female EFL Students
Authors: Alaiyed Majedah A.
Published: September 2024

The current study examined 150 emails sent by Saudi female English as a foreign language (EFL) undergraduate students to their instructor. Greetings (opening moves) and farewells (closing moves) were investigated, exploring how social and interactional factors affected the politeness strategies and language formality employed. The study analyzed the types of opening and closing moves and the students’ ability to use formal forms, considering the formality of the context and their awareness of social distance. Most of the emails did not include opening and closing moves, suggesting a low awareness of politeness strategies. Opening moves were used more frequently than closing moves and when greetings were used in the opening moves, formal greetings were more frequent than less formal ones. Moreover, the use of greetings was affected by the students’ first language. The paper concludes with recommendations to enhance EFL students’ knowledge of politeness strategies.

Opening Interactions Between Inquirers and Employees in Jordanian Public Utility Services
Authors: Sahawneh Meera B. , Al-Ali Mohammed Nahar , Dwairi Raneem B. Al
Published: September 2024

This article investigates the strategic sequential options used to open a real workplace discourse in public utilities between Jordanian inquirers and employees. We examined how these opening moves are co-constructed and function, what linguistic choices are utilized to articulate these moves, and how they reflect socio-cultural relations between the interlocutors. The data reported here were drawn from seven employees and 100 Jordanian inquirers recruited from those approaching the organization and the employees responding to face-to-face inquiries. To achieve this, we adopted Al-Ali and Abu-Abah’s (2021) sequential moves observed in Jordanians’ telephone conversation openings. The moves identified in the data analyzed can be categorized into three groups: cross-culture-free phatic components (Greeting, Question-After-You (QAY)), socio-culture-bound components (Expressing hospitality, Invoking God-wishes, and Introducing oneself), and context-bound components (Expressing annoyance, and Topic introducer). Contextual and socio-cultural practices of Arabic speakers result in new moves that have led to a delayed switch to the core topic. Such a practice can be related to relationships in Arab culture established upon collectivism and indirectness that focus on rapport-building exchanges. Such findings will, hopefully, contribute to understanding how interlocutors use socio-cultural and religious affiliations to co-construct the components of this genre.

Evolutionary Dynamics of a Two-Stage Population with Density-Dependent Regulation of the Survival of Reproductive Individuals
Authors: Neverova G.P. , Frisman E.Ya.
Published: September 2024

The paper studies an evolutionary model of natural selection in a two-stage population with autoregulation of the survival of adult individuals. The population breeds seasonally, and we assume that reproductive potential is determined genetically. The proposed ecological-genetic model is a combination of an ecological model of the dynamics of a stage-structured population and a microevolutionary model of the dynamics of its genetic structure when the adaptive trait of birth rate is controlled by a single diallelic autosomal locus with allelomorphs A and a. We study the proposed model analytically and numerically and determine the parametric regions with different dynamic behaviors. We consider the possibility of changing the dynamic mode due to a variation in the genetic composition of the population. The study shows the genetic composition of the population, namely, whether will it be polymorphic or monomorphic, is mainly determined by the values of the reproductive potentials of heterozygotes and homozygotes. Reduced fitness of the heterozygotes leads to a “bistability trap” when both monomorphic fixed points are attractive, and the initial abundances of stage classes and allele frequencies determine the genotype that will be fixed in the population. However, with density-dependent regulation of the survival of adult individuals, displacement of one of the alleles can lead to the extinction of the population. In general, a change in the direction of evolution may be accompanied by a change in the population dynamics mode.

It is hard to imagine a modern city without parks or other green spaces. Park is not only a place for relaxing or regaining strangth, but also it is a place for local festivities, different sports and a meeting place for friends and families. For reasons mentioned above, it is important to properly manage forest parks and other green territories. Tālavas forest park is located in Alūksne and covers 8.1 hectares. As the popularity of this park grows, it is important to remove all dangerous elements of the forest park. As most of the forest park territory is covered with trees it is important to make sure that all the trees are in good shape. So visual evaluation of trees has been performed. During the study health of trees has been assessed and visual evaluation of trees has been performed. Tree trunk, crown and root quality have been assessed. Also height and diameter of trees were stated. Besides visual evaluation of trees,determination of tree species was performed.After evaluation of trees recommendations for forest park management was made.

Published: September 2024

As known to the prior characteristics of the laser, the new advanced technologies are based on the lasers. It can be used in different ways like scanning, displaying, engraving, cutting, drilling, marking, and many more. In this article, a discussion is made about the use of lasers as a device of visualization in climatic conditions like snow, fog and heavy rain. The existing technology “LiDAR” is one of the systems that will be discussed. LiDAR is a Light Detection and Ranging device used for driving the autonomous vehicles and are also installed on aircrafts in order to scan a vast area like forest, cities, etc. Lidar has been contributing a lot to our intelligence of the Earth’s atmosphere for the past few years [2]. But with so many features, this system has its own limitations, with some conditions such as in bad weather and unable to recognize the white color. In this research two types of red-lasers are being used i.e. Diode and He-Ne Laser, of wavelength 650nm & 632.8 nm respectively. Also a green diode laser of wavelength 532nm is used. With the help of these lasers, we will be able to conclude if the laser is able to reflect back from water, snow and fog or it will pass through them without detecting. With this, we can also justify the loss of power that laser generates.

Liver-first approach in surgical treatment of colorectal cancer with synchronous liver metastases: results of a single-center study
Authors: Mesheryakova Milana Yu. , Trifanov Vladimir S. , Chernichenko Maria A. , Moshurov Ruslan I.
Published: September 2024

BACKGROUND: At the time of initial colorectal cancer diagnosis, synchronous metastases are found in 20–25% of patients. The medical approach, in which liver resection is performed as the first stage of treatment is called liver-first. The rationality of this approach is justified by elimination of the most prognostically significant tumor foci, which are hepatic metastases, with subsequent treatment of primary colorectal tumor.
AIM: To evaluate the immediate and long-term treatment results in patients with metastatic colorectal cancer, focused on surgical removal of synchronous liver metastatic foci as the first stage of treatment.
MATERIALS AND METHODS: A single-center, observational, prospective cohort study was carried out from February 2017 to June 2023 in the abdominal surgical department of the P.A. Herzen Moscow State Medical Institute — a branch of the National Medical Research Radiological Center (Moscow, Russia).
RESULTS: The study included 70 patients (37 men and 33 women). The treatment plan, according to the previously approved protocol, was carried out in 25 patients out of 70 (35.7%). Mean duration of the first stage was 235 min (125–328 min), mean blood loss volume 450 ml (100 ml–1300 ml). Mean hospitalization length was 17 bed days (12–21). The 30-day mortality rate was 12.8% (5 out of 39 patients). Overall, 1-year and 3-year survival rate after second stage of the treatment was 78% and 52%, respectively. At the same time, 1-year progression-free survival rate was 25%, and 3-year survival rate was 11%.
CONCLUSION: In rare clinical situations, when synchronous bilobar liver metastases are accompanied by an asymptomatic primary tumor, the best choice is to follow the liver-first protocol. However, it should be noted that not every patient at stage IV colorectal cancer can be a candidate for combined two-stage treatment, which is determined by somatic status and high risk of disease progression.

Authors: Borisenko Olga V. , Lazarev Alexander F. , Titov Konstantin S.
Published: September 2024

BACKGROUND: Lung cancer is becoming increasingly relevant healthcare issue every year. According to the Altai Regional Oncology Center cancer registry, the incidence of lung cancer in 2019 was 114.8/100 000 in men, 19.3/100 000 in women; in 2020 — 96.8/100 000 and 16.8/100 000, respectively. In 2021, the incidence for both genders was 108.9/100 000. Diagnostic rates in 2022 among patients with respiratory cancer were discouraging: at the time of diagnosis 42.2% had stage IV, 27.9% stage III, 16.3% stage I and 12.9% stage II, and in 0.7% of cases the stage was not established. Distribution of lung cancer patients of different age groups depending on the tumor histotype, showed that the majority are adenocarcinoma and squamous cell lung cancer — 85%.
AIM: To assess the possibility to identify morphological forms of lung cancer (adenocarcinoma, squamous cell and small cell cancer) by using artificial intelligence, based on the results of multispiral computed tomography and additional parameters.
MATERIALS AND METHODS: We used multispiral computed tomography data of patients with lung cancer, analyzed with the “Radiologist+” program (Russia, Barnaul), which allows direct sampling of average pixel densities in tabular form in selected areas of interest from DICOM files for subsequent analysis and statistical processing. The resulting densitometric indicators were incorporated in the artificial neural network.
RESULTS: Data from 485 patients with lung cancer aged 45 to 80 years was analyzed, taking into account nine parameters.
CONCLUSION: Mathematical model for differential diagnosis of histological lung cancer forms, taking into account the presence or absence of tobacco smoking, showed 85.8% sensitivity, 85.0% specificity and 85.4% accuracy.

Authors: Niu Xiangping , Zhang Fuchen , Liu Xiaoping , Yang Bin
Published: September 2024

Steel plates are widely used in various industries and are often processed into important equipment components. During production and use, these plates can develop U-shaped defects due to factors such as impact, vibration and bending. These defects can pose safety hazards under the
influence of stress and fatigue load. To address this issue, this research paper proposes the design of an orthogonally distributed eddy current probe for detecting U-shaped defects in steel plates. The study uses COMSOL simulation and eddy current testing to obtain relevant data, which is
then used to fit the relationship between the length, width, maximum depth and peak voltage of the U-shaped defects. A fitting formula is generated to provide a calculation method for subsequent detection. The results indicate that this type of eddy current inspection probe can effectively
detect U-shaped defects with small dimensions.

Published: September 2024

Aim. Comparative evaluation of the effectiveness of riskometer scales in predicting in-hospital death (IHD) in patients with ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI) and the development of new models based on machine learning methods.

Material and methods. A single-center cohort retrospective study was conducted using data from 4,675 electronic medical records of patients with STEMI (3,202 men and 1,473 women) with a median age of 63 years who underwent emergency PCI. Two groups of patients were isolated: group 1 included 318 (6.8%) patients who died in hospital; group 2 consisted of 4,359 (93.2%) patients with a favorable outcome. The GRACE, CADILLAC, TIMI-STe, PAMI, and RECORD scales were used to assess the risk of IHD. Prognostic models of IHD predicted by the sums of these scale scores were developed using single- and multivariate logistic regression, stochastic gradient boosting, and artificial neural networks (ANN). Risk of adverse events was stratified based on the ANN model data by calculating the median values of predicted probabilities of IHD in the compared groups.

Results. Comparative analysis of the prognostic value of individual scales for the STEMI patients showed differences in the quality of the risk stratification for IHD after PCI. The GRACE scale had the highest prognostic accuracy, while the PAMI scale had the lowest accuracy. The CADILLAC and TIMI-STe scales had acceptable and comparable prognostic abilities, while the RECORD scale showed a significant proportion of false-positive results. The integrative ANN model, the predictors of which were the scores of 5 scales, was superior in the prediction accuracy to the algorithms of single- and multivariate logistic regression and stochastic gradient boosting. Based on the ANN model data, the probability of IHD was stratified into low (<0.3%), medium (0.3-9%), high (9-17%), and very high (>17%) risk groups.

Conclusion. The GRACE, CADILLAC and TIMI-STe scales have advantages in the stratification accuracy of IHD risk in patients with STEMI after PCI compared to the PAMI and RECORD scales. The integrated ANN model that combines the prognostic resource of the five analyzed scales, had better quality criteria, and the stratification algorithm based on the data of this model was characterized by accurate identification of STEMI patients with high and very high risk of IHD after PCI.

AI and the Increase of Productivity and Labor Inequality in Latin America: Potential Impact of Large Language Models on Latin American Workforce
Authors: Azuara Herrera Oliver , Ripani Laura , Torres Ramirez Eric
Published: September 2024

We assess the potential effect of large language models (LLMs) on the labor markets of Chile, Mexico, and Peru using the methodology of Eloundou et al. (2023). This approach involves detailed guidelines (rubrics) for each job to assess whether access to LMM software would reduce the time required for workers to complete their daily tasks. Adapting this methodology to the Latin American context necessitated developing a comprehensive crosswalk between the Occupational Information Network (O*NET) and regional occupational classifications, SINCO-2011 and ISCO-2008. When we use this adaptation, the theoretical average task exposure of occupations under these classifications is 32% and 31% for each classification. Recognizing the unique characteristics of each country's labor market, we refined these ratings to reflect better each nation's capacity to adopt and effectively implement new technologies. After these adjustments, the task exposure for SINCO-2011 drops to 27% and for ISCO-2008 to 23%. These adjusted exposure ratings provide a more accurate depiction of the real-world implications of LLM integration in the Latin American context. According to this methodology, the LLM-powered exposure using GPT-4 estimates suggests that the percentage of jobs with task exposure exceeding 10% is 74% in Mexico, 76% in Chile, and 76% in Peru. When we raise the exposure threshold to 40% or more, the proportion of affected occupations significantly decreases to 9% in Mexico, 20% in Chile, and 6% in Peru. The exposure is close to zero after this threshold. In other words, the exposure would only affect less than half of the total labor force in these countries. Further analysis of exposure by socioeconomic conditions indicates higher exposure among women, individuals with higher education, formal employees, and higher-income groups. This suggests a potential increase in labor inequality in the region due to adopting this technology. Our findings highlight the need for targeted policy interventions and adaptive strategies to ensure that the transition to an AI-enhanced labor market benefits all socio-economic groups and minimizes disruptions.
Evaluation of Neuroprotective Effect of Salicin in an Experimental Animal Model of Streptozotocin Induced Diabetic Neuropathy
Authors: Jadhav Ghanshayam B. , Khairnar Shubham J. , D'Souza Simona E. , Udavant Pavan B.
Published: September 2024

Background: Diabetic neuropathy stands as the most prevalent secondary complication connected with diabetes mellitus. The susceptibility of mammalian nerves to oxidative stress is heightened due to their rich phospholipid content, leading to a reduced ability to counteract the free radicals responsible for neuropathy. While synthetic treatments can help alleviate oxidative stress, they often come with unwanted side effects. Shifting the focus towards natural pharmaceuticals could mitigate these negative effects. Phenolic compounds abundant in antioxidants may aid in reducing oxidative stress. Aim: Assess the preventive influence of Salicin, a phenolic compound against diabetic neuropathy induced by Streptozotocin (STZ). Methods: Four weeks following the injection of STZ into the peritoneal cavity, a noticeable reduction in thermal and mechanical hyperalgesia, cold allodynia, motor coordination and locomotor activity was noted. Natural antioxidants such as reduced glutathione and catalase were assessed along with lipid peroxidation levels on the 28th day and the sciatic nerve was subjected to histopathological examination. Results: Orally administering Salicin at dosages of 10, 15, and 20mg/kg over 28 days successfully mitigated the reduction in the nociceptive threshold and bolstered the levels of endogenous antioxidants. It also mitigated the unwanted histopathological changes effectively based on the dosage. Conclusion: Salicin having antioxidant properties, demonstrates potential in alleviating diabetic neuropathic pain and preventing associated complications.

Background: Respiratory disorders lead to mental stress and reduce the quality of life. Hence, there is a need to intervene with traditional healthcare systems. One such healthcare system being practised in the Southern Peninsula is Siddha. Siddhars used herbs, inorganic substances, and animal products to formulate a medicine for maintaining the balance of trihumors (Vali, Azhal and Aiyam). Sarva Sangaara Uppu Parpam is one of the formulations made using herbs indicated for respiratory disorders. Aim: The current study was carried out to analyse the antihistamine and antimicrobial of Siddha medicine Sarva Sangaara Uppu Parpam (SSUP). Methods: Antihistaminic activity was done by isolated chick ileum method and anti-microbial activity for respiratory pathogens like Streptococcus pneumoniae, Staphylococcus aureus, Klebsiella pneumonia, Candida albicans, Escherichia coli, Pseudomonas aeruginosa was determined by disc diffusion method. Result: The results show a statistically significant difference in the response curve of histamine with mean and standard deviation values of 6.5 and 2.258 at p < 0.001. Thus, the drug was effective against pathogens such as K. pneumonia, P. aeruginosa and fungal pathogen C. albicans with a maximum inhibitory zone of 12 mm. This medicine has antihistaminic and antimicrobial activity against K. pneumoniae, P. aeruginosa and C. albicans.

Kontrollok az önkormányzati hitelezésben – az elmúlt évtized tanulságai

In parallel with debt consolidation and the centralization of municipal responsibilities, the Hungarian government implemented both active and passive regulatory measures to mitigate public finance risks originating at the subnational level. This study offers a comprehensive overview of the developments in the financial situation, credit demand, and credit supply within the subnational sector over the past decade. Our findings indicate that the implemented measures have effectively met their objectives from a public finance perspective. The level of local government debt is notably low even by European standards, and the rate of indebtedness has decelerated by approximately one-third. Accordingly, the role of the local government sector has shifted from the active (lending) side to the passive side from a banking perspective, primarily shaped by liquidity management considerations. However, the economic upheavals witnessed in 2022 and the substantial budget deficit underscore the potential risks associated with an overreliance on central transfers. While the active oversight of local government credit transactions has successfully counterbalanced the positive effects of debt consolidation on credit supply, it is crucial to acknowledge that political considerations also influence the approval of loan transactions.

The local environment is a determining factor in the concentration of industrial activities, service providers and related research and development capacities. In recent decades, industrial parks, local innovation environments and incubators have undergone significant changes in Hungary. Little research has addressed the specificities that help incoming entities to become meaningfully integrated into the value chain of the ecosystem. However, practical experience suggests that the professional, sectoral, and industry focus of innovation ecosystems is a distinctive feature of cooperation and research in this area is warranted. The authors contribute to covering this research gap with the current analysis. The aim is to evaluate sectoral characteristics based on the empirical examination of different ecosystems in Hungary. The conclusions describe different patterns, which can characterise certain types of ecosystems, considering their range of activities and sectoral concentration. As part of the discussion, the authors propose a method for describing the sectoral focus of an innovation ecosystem based on the activities of the settled players.

Published: September 2024

The web-based PV system monitoring to measure electrical production and consumption to the load or utility grid is presented in this paper. This monitoring system consists of an Arduino Mega 2560 with two PZEM 004T sensor modules. The monitoring system has been designed to store measurement data of current, voltage, power and energy in the database and display on the webpage in real time and infographics history. The PZEM sensor measurement has been tested with an average power difference 0.29% less than IEC-61724 minimum-accuracy. Realtime data is obtained in the form of one-line data for every 2 seconds, with a data size of 375-byte and 75ms delivery delay. For one day period testing, the electrical energy that can be generated by the PV system is 5,925 kWh, while the power consumed by the load is only 1,272 kWh so the accumulated electrical energy that can be exported is 4.65 kWh. The test results show that the system has been able to measure net energy export or import by the PV system to utility grid.
