Sustainability of Water Resources in Karst Undermined by Tunneling: A Case Example
Authors: Dvanajščak Drago , Ratej Jože , Jovičić Vojkan
Published: January 2022

Water resources in karsts are scarce due to the high cavernosity in the otherwise low-permeability limestone rock mass. The highly variable porosity and transmissivity of karst aquifers are caused by a network of channels, caverns, and caves that typically act as water-bearing, connected vessels. Tunneling in a karst environment can severely deplete an aquifer and undermine the sustainability of water resources over the long term. A research study was carried out to elaborate and develop measures for the sustainable preservation of the water resources in a Slovenian karst, in which two approximately 7 km-long tunnels will be driven as part of the construction of the new Divača–Koper railway line. Hydrogeological site investigations were carried out with an aim to evaluate the transmissivity and spatial spreading of the karst aquifer along the route of the tunnels, including the observation of the long-term variation of the groundwater levels and trace experiments. The main findings, which are presented in this paper, were used to develop a methodology for the selection of adequate measures for tunnel construction with an aim of ensuring the sustainability of water resources in karst aquifers. The construction measures comprise limiting the inflows using injection grouting, obscuring the groundwater intake by undrained sections of the tunnel, and constructing bypasses around the tunnel to preserve the current groundwater flow regime. The presented methodology of dynamically accommodating the preventive measures to the actual hydrogeological conditions onsite is generally applicable for common cases in which the state of the karst aquifer could not be pre-determined with a sufficient accuracy of tens of meters to a meter. The spatially and temporally continuous hydrogeological investigations and decision-making charts to reduce the tunnelling’s impact on the karst aquifer are explained in detail in this paper.
A Simplified Tantalum Oxide Memristor Model, Parameters Estimation and Application in Memory Crossbars
Authors: Mladenov Valeri , Kirilov Stoyan
Published: January 2022

In this paper, an improved and simplified modification of a tantalum oxide memristor model is presented. The proposed model is applied and analyzed in hybrid and passive memory crossbars in LTSPICE environment and is based on the standard Ta2O5 memristor model proposed by Hewlett–Packard. The discussed modified model has several main enhancements—inclusion of a simplified window function, improvement of its effectiveness by the use of a simple expression for the i–v relationship, and replacement of the classical Heaviside step function with a differentiable and flat step-like function. The optimal values of coefficients of the tantalum oxide memristor model are derived by comparison of experimental current–voltage relationships and by using a procedure for parameter estimation. A simplified LTSPICE library model, correspondent to the analyzed tantalum oxide memristor, is created in accordance with the considered mathematical model. The improved and altered Ta2O5 memristor model is tested and simulated in hybrid and passive memory crossbars for a state near to a hard-switching operation. After a comparison of several of the best existing memristor models, the main pros of the proposed memristor model are highlighted—its improved implementation, better operating rate, and good switching properties.

Published: January 2022

Rapid identification of patients likely to develop pulmonary complications in severe leptospirosis is crucial to prompt aggressive management and improve survival. The following article is a cohort study of leptospirosis patients admitted at the National Kidney and Transplant Institute (NKTI). Logistic regression was used to predict pulmonary complications and obtain a scoring tool. The Kaplan–Meir method was used to describe survival rates. Among 380 patients with severe leptospirosis and kidney failure, the overall mortality was 14%, with pulmonary hemorrhage as the most common cause. In total, there were 85 (22.4%) individuals who developed pulmonary complications, the majority (95.3%) were observed within three days of admission. Among the patients with pulmonary complications, 56.5% died. Patients placed on mechanical ventilation had an 82.1% mortality rate. Multivariate analyses showed that dyspnea (OR = 28.76, p < 0.0001), hemoptysis (OR = 20.73, p < 0.0001), diabetes (OR = 10.21, p < 0.0001), renal replacement therapy (RRT) requirement (OR = 6.25, p < 0.0001), thrombocytopenia (OR = 3.54, p < 0.0029), and oliguria/anuria (OR = 3.15, p < 0.0108) were significantly associated with pulmonary complications. A scoring index was developed termed THe-RADS score (Thrombocytopenia, Hemoptysis, RRT, Anuria, Diabetes, Shortness of breath). The odds of developing pulmonary complications were 13.90 times higher among patients with a score >2 (63% sensitivity, 88% specificity). Pulmonary complications in severe leptospirosis with kidney failure have high mortality and warrant timely and aggressive management.

Published: January 2022

Background: Levels of fear have increased since the COVID-19 pandemic outbreak. The absence of a safe and effective vaccine for mass-vaccination deteriorates this situation, which has a significant impact on mental health. This study aimed to assess the feelings of fear among nurses and nursing students in five European countries. Methods: A multicenter cross-sectional study was conducted in five European countries (Greece, Albania, Cyprus, Spain, and Kosovo) before the start of mass vaccination in Europe. Data collection was conducted in December 2020–January 2021 using an online questionnaire for nursing students and professional nurses. Fear of COVID-19 Scale (FCV-19S) was used for measuring levels of fear. IBM SPSS version 21.0 was used for statistical analysis. Results: The study population included 1135 nurses and 1920 nursing students from Kosovo (n = 1085), Spain (n = 663), Greece (n = 534), Albania (n = 529), and Cyprus (n = 244). According to multivariable analysis, females (OR = 2.53, 95% CI = 1.89–3.15), married (OR = 0.86, 95% CI = 0.24–1.48), nurses (OR = 0.87, 95% CI = 0.28–1.45) and those with a chronic disease (OR = 0.86, 95% CI = 0.11–1.62) were more fearful of COVID-19. Conclusions: It is important to decrease fear in the population of nurses who are at the frontlines of the pandemic. The provision of appropriate education and training activities for nurses and students to manage their stress levels is of high importance. Future studies should focus on levels of fear after the administration of several safe and effective vaccines worldwide.
Machine Intelligent Hybrid Methods Based on Kalman Filter and Wavelet Transform for Short-Term Wind Speed Prediction
Authors: Patel Yug , Deb Dipankar
Published: January 2022

Wind power’s increasing penetration into the electricity grid poses several challenges for power system operators, primarily due to variability and unpredictability. Highly accurate wind predictions are needed to address this concern. Therefore, the performance of hybrid forecasting approaches combining autoregressive integrated moving average (ARIMA), machine learning models (SVR, RF), wavelet transform (WT), and Kalman filter (KF) techniques is essential to examine. Comparing the proposed hybrid methods with available state-of-the-art algorithms shows that the proposed approach provides more accurate prediction results. The best model is a hybrid of KF-WT-ML with an average R2 score of 0.99967 and RMSE of 0.03874, followed by ARIMA-WT-ML with an average R2 of 0.99796 and RMSE of 0.05863 over different datasets. Moreover, the KF-WT-ML model evaluated on different terrains, including offshore and hilly regions, reveals that the proposed KF based hybrid provides accurate wind speed forecasts for both onshore and offshore wind data.

Published: January 2022

Background: Pneumatic balloon dilation (PBD) is a first line treatment for idiopathic achalasia. Here we report the safety and efficacy of graded gradual PBD on short and long-term follow-up. Methods: We evaluated 1370 idiopathic achalasia patients over a period of 24 years (1994-2018), prospectively. 216 patients did not undergo PBD due to comorbid diseases. Ultimately, 1092 achalasia patients were enrolled. All patients underwent graded gradual PBD, with repeat dilation if symptoms relapsed. Response to treatment was evaluated by Vantrappen scoring system. Results: Of 1092 achalasia patients, 937 patients were treated by PBD and 155 patients were treated by combined therapy (PBD 1 month after Botulinum toxin injection). In short-term follow-up, 728 of 1092 patients underwent one PBD and 77.3% of them had excellent or good response (responders), 163 patients (58.6%) who underwent two PBDs were responders, and 44 (51.2%) patients who underwent three PBDs were responders. Overall, 2193 balloon dilations were performed on 1092 patients (mean 2 PBDs/patient). Of 786 patients with long-term follow-up, 259 patients had excellent or good response with one PBD. The responders with two, three, and four or more dilations were 149, 67, and 67, respectively. The overall response rate was 69%. No any serious complications were noted by using the graded gradual method. Conclusion: Our results show that graded gradual PBD is a safe and effective method for treatment of achalasia patients, and achieves sufficient short and long-term symptomatic remission with high cumulative success rate.

Background: Little is known regarding the impact of quantity and quality of sleep on the incidence of cardiovascular disease. The aim of this study was to investigate the possible independent association of late bedtime and premature coronary artery disease (PCAD). Methods: Between October 2016 and November 2019, we conducted a cross-sectional population-based study on 30101 participants aged 20–65 years in Khuzestan Comprehensive Health Study (KCHS). Data on major risk factors of cardiovascular disease, habit history, physical activity, and sleep behavior was gathered and participants underwent blood pressure, anthropometric, and serum lipid and glucose profile measurements. PCAD was defined as documented history of developing obstructive coronary artery disease before 45 years in men and before 55 years in women. Results: Of a total of 30101 participants (64.1% female, mean age: 41.7±11.7 years) included in this study, 1602 (5.3%, 95% confidence interval: 5.1%–5.6%) had PCAD. Late bedtime was reported in 7613 participants (25.3%, 95% confidence interval: 24.9%–25.8%). Age-sex standardized prevalence for PCAD and late bedtime were 3.62 (3.43-3.82) and 27.8 (27.2–28.4), respectively. There was no significant difference (P=0.558) regarding prevalence of PCAD between those with late bedtime (5.5%, 95% CI: 4.9%–6.0%) and those with early bedtime (5.3%, 95% CI: 5.0%–5.6%). However, after adjustment for potential confounders, late bedtime was independently associated with PCAD (OR=1.136, 95% CI=1.002–1.288, P=0.046). Conclusion: In this study, late bedtime was significantly associated with presence of PCAD. Future prospective studies should elucidate the exact role of late bedtime in developing coronary atherosclerosis prematurely.

Published: January 2022

Background: Despite advances in the treatment of abdominal injuries in patients with trauma, it remains a major public health problem worldwide. Evaluation of hazard ratio (HR) of 90-day mortality in intensive care unit (ICU) patients with abdominal injuries compare with head injuries in trauma patients and non-trauma surgical ICU patients. Methods: This single-center, prospective cohort study was conducted on 400 patients admitted to the ICU between 2018 and 2019 due to trauma or surgery in Hamadan, Iran. The main outcome was mortality at 90-day after ICU admission. Cox proportional hazards models were used to determine the HR and 95% confidence interval (CI) for 90-day mortality. Results: The 90-day mortality was 21.9% in abdominal injuries patients. According to multivariate Cox regression, the expected hazard mortality was 2.758 times higher in patients with abdominal injuries compared to non-trauma patients (HR: 2.758, 95% CI: 1.077–7.063, P=0.034). About more than 50% of all deaths in the abdominal and head trauma groups occurred within 20 days after admission. Mean time to death was 27.85±20.1, 30.27±18.22 and 31.43±26.24 days for abdominal-trauma, surgical-ICU, and head-trauma groups, respectively. Conclusion: Difficulty in accurate diagnosis due to the complex physiological variability of abdominal trauma, less obvious clinical symptoms in blunt abdominal injuries, multi-organ dysfunction in abdominal injuries, failure to provide timely acute care, as well as different treatment methods all account for the high 90-day mortality rate in abdominal-trauma patients. Therefore, these patients need a multidisciplinary team to care for them both in the ICU and afterwards in the general ward.

The drying process is very intensive in energy consumption. Mexico is a major producer of food, especially of varieties of chilies, with quality culinary and medicinal properties. The 65% of the national market as a dry product, which gives a benefit. In the drying process, the convective technology was used, using a horizontal tunnel with direct solar heating air. The kinetics of the solar dryer with direct heating is possible, with an average drying time of 16 hours of solar irradiance. The tests were performed in Temixco, Morelos, Mexico, located at 18 º 51 'of LN and 99º 14' of LO, with average values of 850 W/m2 irradiance maximum. The chamber temperatures were in a range between 31 and 45 °C. The air velocity range was set between 1.3 and 2.4 m/s. Final moisture contents of the dried chili were obtained in a range between 8% and 6% h.b. with an average drying velocity of 4.7 humidity degree/h. The solar direct drying is a technology that allows recovering and trying different agricultural surpluses and could promote the establishment of agro-industries.

THE NAMES FOR SNIPE BIRD (GALLINAGO GALLINAGO) IN UDMURT DIALECTS
Authors: Arzamazova Olga Alexandrovna , Nasibullin Rif Shakrislamovich
Published: January 2022

The article discusses the Udmurt dialect names of the snipe bird (Gallinago gallinago), which is from the snipe family of the Charadriiformes order. The main sources are field dialect materials of the Laboratory of Linguistic Mapping and Historical Lexicology of Udmurt State University, collected within the project “Dialectological Atlas of the Udmurt language”. In this paper methods of linguo-geographical description, structural-semantic and etymological analysis of words are used. Udmurt names for snipe appeared during the period of independent development of the language. In the Udmurt dialects, the most frequently recorded word is n'urtaka , formed from the n'urvyltaka form due to contraction. We believe that it is the most ancient name for the snipe. The main motivation used in the snipe nomination is a sound similar to the bleating of a ram, which is emitted by a displaying male snipe. Most of the lexical variants have a two-component structure formed from original and borrowed nouns. The first component is an attributive noune. It indicates the habitat / nesting place of the bird ( n'ur ‘marshy’, muvyr ‘terrestrial’), characterizes its nocturnal lifestyle ( uy ‘nocturnal’), expresses belonging to the wild nature ( lud , kyr ‘wild’) and the class Birds ( in' ‘heavenly’). The second component is the name of domestic animals ( taka ‘ram’, ketchtaka ‘goat’, kaza ‘she-goat’). Typological similarity of the snipe nomination processes is observed in some related and unrelated languages. Such coincidence of motivation and semantic structures of words is due to the biological characteristics of this bird.
HODONYMIC VOCABULARY IN THE UDMURT LANGUAGE (BASED ON THE MATERIAL OF TOPONYMY)
Authors: Kirillova Lyudmila Jevgenyevna
Published: January 2022

The article considers geographical terms for designating streets and lanes in the Udmurt language based on the study of a large corpus of godonyms. In the study of microtoponyms collected by the author and other toponymists on the territory of Udmurtia and beyond of it - in the places of residence of Udmurts - the author managed to identify a significant number of words expressing these concepts. The words ulcha and uram are used to express the concept of ‘street’ in the Udmurt language, which is confirmed by the data of Udmurt toponymy. Special attention is paid to the description of common nouns with the meaning ‘lane’ recorded in microtoponyms, since this layer of vocabulary has not yet been considered in detail by anyone. The performed review indicates that a number of lexemes can act as common words used in this meaning. Taking into account different variants, the author identified 13 units in total. The etymological analysis of the analyzed geographical terms suggests that they are heterogeneous in origin. The common nouns borrowed from the Russian language are wide spread. Geographical terms of Udmurt and pre-Permian or Finno-Permian origin have a slightly lower frequency of use. A small number of lexemes are derived from the Turkic languages. Mixed Udmurt-Russian and Udmurt-Tatar formations are represented in a single number.
SPACE DISCOURSE IN A LANGUAGE CONTACT SITUATION: “US” VS. “THEM”
Authors: Dezi Alessandra , Kostandi Elizaveta
Published: January 2022

Multilingual practices inevitably lead to language contact phenomena. This phenomenon occurs in Estonia, where the Russian speaking minority, often defined as a Russian diaspora, differs from the socially and linguistically dominant Estonian group with respect to their language and language practices. We suggest that the analysis of one of the languages in contact, in this case Russian, allows for a deeper understanding of the role of the other, i.e. Estonian, in the multilingual practices of the Estonian population as a whole. In this paper, we will focus on “spatial indicators” (i.e. toponyms, ergonyms, linguistic landscape objects, etc.) in the discourse on space provided by participants from the Russian-speaking population living in Estonia. These sociolinguistic foci have been partially described in several existing works which underscore the influence of Estonian on the speech of the local Russian speakers. Previous research gives insights into the peculiarities that the influence of Estonian generates: in the use of toponyms, in the naming of different language landscape objects, in the everyday language practices, and in the description and evaluation of the surrounding space (i.e. in the “spatial awareness”) of the local Russian speaking population. However, little attention has been paid to the fact that the aforementioned phenomena represent a whole that reflects the development of the speakers’ apprehension of the surrounding physical, sociocultural and sociolinguistic space. This process is put into focus in this paper and is shown to be characterized by the (re)definition of space(s) as “ours” vs “theirs”. Such processes will be revealed here by giving an overview of the “spatial components” in the speech of the Russian speaking population of Estonia in several spheres of communication (newspapers, TV shows, advertisements, web forums, etc.) and by analysing interviews involving three Estonian residents, each with a different sociolinguistic background. We attempt to demonstrate how these “spatial components” reflect the interaction of Russian and Estonian speakers, with an emphasis on their affinities across certain language practices. In the analysis of the interviews, we focus in particular on the participants’ (re)definitions of “us” vs “them” in their discourse on space. Special attention is also given to the use of Estonian insertions as a tool for evaluation and the creation of the opposition between “us” and “them” in the internet communication of Russian speakers living in Estonia.
