Published: June 2023

Aim: Acute rheumatic fever (ARF) is an inflammatory disease that develops after Group A Streptococcal (GAS) tonsillopharyngitis in genetically susceptible individuals. We aimed to examine the clinical, laboratory, and echocardiographic findings of the patients diagnosed and followed up with ARF.

Methods: 55 patients under the age of 18 who were hospitalized and followed up with the diagnosis of ARF between January 2017 and January 2019 were included in this retrospective study. All cases were diagnosed with ARF according to the 2015 revised Jones criteria according to the intermediate-risk group. Gender, age, time of admission, physical examination findings, laboratory findings, echocardiographic findings, and data meeting major and minor diagnostic criteria of all patients diagnosed with ARF were recorded. Echocardiography and electrocardiography were performed on all patients. Inflammatory biomarkers were calculated using laboratory parameters. The data before the treatment and at the 8th week of the treatment were compared.

Results: 31 (56.4%) of the patients were female and 24 (43.6%) were male, the mean age was 13.70±2.44 years (7-18 years). The highest number of patients was in the 9-14 age group. The most frequent hospital admission season was winter. Arthritis and carditis were the most common major criteria. Post-treatment body weight, height, body mass index, and systolic and diastolic blood pressure values of the patients were statistically significantly higher than before treatment (p

Background/Aims : Urinary tract infections are an important cause of mortality, especially in geriatric patients. The effectiveness of urine culture and appropriate antibiotic use in geriatric patients followed in primary care is unknown. We aimed to compare the urine cultures and antibiotic susceptibility of patients over the age of 65 who were treated at home by the Home Health Services (ESH) and inpatients in the Palliative Care Service (PBS).

Methods: Our study retrospectively compared the culture-antibiogram results of urine samples of patients aged 65 years and older with urinary infection complaints and followed and treated by PBS and ESH between January 1, 2019 and January 1, 2020.

Results: Of the 60 patients included in the study, 30 had PBS, 30 ES Services patients had a mean age of 78.0±12.7 years, and PBS patients had a mean age of 80.7±9.8 years. According to the culture-antibiogram results of the urine samples of the patients, E.coli was the most common microorganism in both groups (p=0.003).

When we look at the antibiotic sensitivity of the patients in the ESH group, Amikacin (96.7%), Cefoxitin (83.3%), Fosfomycin (73.3%), Nitrofurantoin (70%) sensitive and Ampicillin (76.7%) Cefuroxime (36%) ,7) Ceftazidime(40%) was found resistant to Ciprofloxacin(33%).

PBS group is sensitive to Amikacin(60%), Cefoxitin(23.3), Fosfomycin(23.3%), Nitrofurantoin(16.6%) and Ampicillin(40%), Cefuroxime(26.7%), Ceftazidime( 33.3% were found to be resistant to Ciprofloxacin(53.3%).

In both groups, the highest resistance rates were found in Ampicillin, 76.7% in ESH patients and 40% in PBS patients, and the highest sensitivity rates were in Amikacin, 96.7% in ESR and 60% in PBS.

Conclusion: In this study conducted over the age of 65, empirically in ESR in urinary system infections; on the other hand, it would be rational to use oral Fosfomycin or Nitrofurantoin or Amikacin; It is thought that due to high antibiotic resistance in PBS, caution should be exercised.

Aim: This study aimed to investigate whether breastfeeding in early childhood affect the risk of devoloping inflammatory bowel disease (IBD).

Materials and Methods: The data of patients obtained from the survey were compared to the data of their non-IBD siblings as a control group. The relationship between the demographic and clinical chararecteristics of IBD patients and breastfeeding was also analyzed.

Results: 304 IBD patients were included in the study. 182 (59.9%) of the patients were diagnosed with ulcerative colitis (UC), and 122 (40.1%) with Crohn’s disease (CD). The CD patients included in the study were compared to the CD siblings group of 332, and the UC patients compared with the UC siblings group of 508. Compared to the control groups, the proportion of those who never breastfed was higher in both the CD and UC groups (7.4% vs. 2.1% for CD [p=0.017] and 3.9% vs. 0.8% for UC [p=0.01]), and the risk of disease increased in those who was not breastfed (OR= 3.70 [1.35-10.16] for CD [p=0.017] and OR= 5.07 for UC [1.47-17.53] [p=0.010]). The protective effect against CD increased as the duration of breastfeeding increased, but that the protection increased with breastfeeding for up to 12 months for UC, and breastfeeding for more than 12 months did not provide additional protection. There was no relationship between breastfeeding and demographic and behavioral chracteristics of patients

Conclusions: Not having been breastfed in infancy increases the risk of developing both UC and CD, and as the duration of breastfeeding increases, the protection against diseases risk increases.

Published: June 2023

Aim We aimed to determine the relationship of Pro-BNP levels, with the diagnosis, clinical, and laboratory parameters in children. In addition, the predictive power of the Pro-BNP levels in determining the cardiovascular events was evaluated.

Patients and methods: This study comprised 829 patients whose levels of Pro-BNP were measured. The data were obtained retrospectively from the hospital records. The relationship of the Pro-BNP level of the patients with the clinical, laboratory, and echocardiographic data was determined. The predictive power of the Pro-BNP and Troponin T levels in determining the development of cardiovascular events was evaluated.

Results: Cardiovascular events developed in 143 patients during the follow-up period. The Pro-BNP levels were observed to be significantly higher (p< 0.001) in the group in which patients developed cardiovascular events. The Pro-BNP levels demonstrated a positive correlation with both Troponin T levels and procalcitonin levels and a strong negative correlation with the age, height, and weight of the patients. The most important predictive factors for determining the development of cardiovascular events were the presence of tachypnea, increased Pro-BNP levels, increased left ventricular end-diastolic diameter, and increased tricuspid regurgitation velocity.

Conclusion: The most important determinants of a cardiovascular event, as revealed in the present study, are the presence of tachypnea, Pro-BNP levels, TR velocity, and the LVEDD z-score of patients. Moreover, the Pro-BNP levels and Troponin levels demonstrate a strong positive correlation. Randomized prospective studies are warranted to improve the efficacy of using Pro-BNP in differentiating cardiac and non-cardiac diseases in children.

Published: June 2023

Aim: Increased emergency department (ED) admissions and the need for intensive care unit (ICU) brought with the pandemic has led to the need to make fast and accurate decisions. Early warning scores (EWS) may be useful in ED in this regard. This study was performed to evaluate the effectiveness of EWS in predicting mortality and need for ICU of patients with COVID-19.

Materials and methods: This retrospective observational study was performed with subjects presented to the ED and were later admitted to a general ward or to the ICU because of COVID-19. Subjects aged ≥18 years with positive RT-PCR were included in the study. Subjects experienced a cardiac or respiratory arrest or intubated at the time of presentation to the ED and pregnant women were excluded from the study. MEWS, NEWS, NEWS-2, REMS, and qSOFA scores were calculated using patients’ data on first presentation. We examined the association of these scoring systems with mortality and need for ICU.

Results: While 60(10%) of the 600 patients participating in the study were admitted to the ICU, 222(37%) patients died. The scoring systems’ negative predictive values for predicting ICU admission were 0.95, 0.98, 0.97, 0.96, and 0.96 respectively and for predicting mortality were 0.61, 0.67, 0.67, 0.66, and 0.61 respectively. All scorings assessed were significant predictors of the need for ICU and mortality in patients with COVID-19.

Conclusions: All evaluated scoring systems were successful; however, NEWS and NEWS-2 had the highest predictive value both for the need for ICU and mortality.

Published: June 2023

Os problemas ambientais nunca antes foram tão emergentes e fazer algo a respeito é necessário. Considerando que as empresas são um dos maiores agentes poluidores e geradores de resíduos, sua participação se apresenta como uma das principais na construção de uma sociedade mais sustentável. Nesse sentido, o que encontramos são várias campanhas objetivando conscientizar e trabalhar gestão ambiental e outros aspectos, porém, sem termos certeza se os resultados são efetivos. Diante disso, esse trabalho encontra-se em fase de desenvolvimento e tem o objetivo de analisar as estratégias para sustentabilidade de micro e pequenas empresas no município de São Luís do Maranhão. Foi elaborado a partir da pesquisa bibliográfica seguindo as etapas da formulação do problema, seleção de textos, avaliação dos textos, análise e interpretação e redação. Os resultados parciais delinearam a noção conceitual de sustentabilidade, micro e pequenas empresas, logística reversa, entre outros. As considerações parciais demonstram que o conceito de sustentabilidade é apontado como contraditório e que há muita dificuldade na identificação de dados sobre as micro e pequenas empresas.

Authors: Freitas André Rodrigues de , Petrus Júlia Kátia Borgneth
Published: June 2023

São Luís é palco de diversidade cultural e demonstra aspectos socioambientais que a colocam sob visibilidade turística, política e acadêmica durante boa parte de sua história. Os processos industriais, em meio ao século XX, tornam a cidade cenário para grandes transformações que serão debatidas dentro de um cerco espaço-temporal delimitado pelo urbano, a relação com o rural e o pós 1950, período que determina mudanças na capital e traz problemáticas do moderno, como o surgimento de novas divisões, grandes empreendimentos de infraestrutura e mobilidade, bem como o aumento acentuado da população e o surgimento de áreas marginalizadas. Este trabalho tem por objetivo analisar o processo de ocupação, a relação de expansão urbana e políticas públicas de planejamento, e as influências sobre o território da capital do Estado do Maranhão através do Plano Diretor Municipal. Para tal, será necessário, comparar as relações intra-urbanas e suas expansões ao longo das últimas décadas, para então definir influências no processo de territorialização da cidade que gera conflitos sociais, a escassez de debates sobre a política urbana e a paradoxal espacialização contemporânea da cidade Patrimônio. A pesquisa parte de um estudo empírico, de abordagem quali-quantitativa, natureza básica, objetivo descritivo e procedimentos de estudo de caso. Como hipóteses temos: o silenciamento dos indivíduos na construção de uma política urbana eficiente em ações possíveis do Plano Diretor; a cidade e os indivíduos sem integração de ações público-privadas mediadas pela função social desta legislação tomando o caos urbano como resultante negada do desenvolvimento propagado pela ideia de progresso.

Introduction. There is a growing need to implement evidence-based psychological treatments for women victims of intimate partner violence (IPV) who commonly experience stress-related disorders such as anxiety, depression, or suicide risk, as well as altered cortisol reactivity. Objective. 1. To compare the changes in depressive and anxious symptomatology, quality of life, and cortisol reactivity after two different interventions, Acceptance and Commitment Therapy (ACT, based on psychological flexibility) or Interpersonal Therapy (IPT, based on empowerment) in women exposed to IPV. 2. To compare the changes in relation to the presence of suicide thoughts. Method. A clinical sample of 50 women (ages 21-74) randomly assigned to attend ACT or IPT, completed pre- and post-intervention questionnaires about intimate partner violence, quality of life, depression, anxiety, and measurements of salivary cortisol reactivity (basal, 15, 30, and 45 minutes after a cognitive challenge). We used Generalized Estimating Equation Models for data analysis. Results. There was a significant improvement post-intervention in all variables, regardless of the type of psychotherapy or the presence of suicide thoughts. Before interventions, women that reported suicide thoughts had severe symptoms of depression, anxiety, worse quality of life, and a cortisol hyper-response profile, in contrast to women without suicide thoughts who had moderate symptoms and no cortisol response. Cortisol response to the cognitive test decreased in all women after both therapies. Discussion and conclusion. Although different psychological approach, ACT, and IPT effectively improved mental health, quality of life, and changed cortisol reactivity of women exposed to IPV, including women at suicide risk.

INTRODUCTION: Rural medicine is in many ways different from urban primary care. In addition to providing primary care for a population, the rural doctor is tasked with the initial evaluation and stabilization of all emergencies usually managed by an Emergency Department in urban areas. The goal of this study was to assess rural doctors‘ in Iceland attendance of courses in Emergency Medicine (EM), how rural doctors grade their own ability to respond to emergencies and evaluate their Continuous Medical Education (CME) within the field of EM. MATERIALS AND METHODS: In this descriptive cross-sectional study, all rural general practitioners (GP) in Iceland with at least two years of experience post foundation training and who practiced at least a quarter of every year outside the capital area were surveyed using an electronic questionnaire. T-test and qi-square test were used for analysis and significance determined if p<0.05. RESULTS: The survey was sent to 84 doctors with 47 (56%) completing the survey. Over 90% of the participants reported having completed a course in Advanced Life Support (ALS) but only 18% had completed a course in prehospital EM specifically designed for this group of doctors. Over half of the participants considered themselves to have good training to perform 7 out of 11 surveyed emergency procedures. Over 40% of participants considered it necessary to improve their CME in 7 out of 10 categories of EM. The majority of rural GPs considered shortage of doctors in the rural environment a significant factor limiting their CME. CONCLUSIONS: The majority of rural doctors in Iceland consider themselves to have a good training to provide initial EM care in their community. Efforts to improve their training in this field of medicine should focus on scene safety and working in the prehospital setting, pediatrics, labor and deliveries and gynecological emergencies. Rural doctors need to have access to appropriate EM training courses.

Authors: Özkan Furkan , Haznedar Bülent
Published: June 2023

In order to sustain human life without problems, a rational planning is required for the conservation and use of existing water resources. The potential of future water sources should be determined as the first step in such planning. Therefore, river flow forecasting is necessary to provide basic information about a variety of problems related to the operation of river systems. In this study, the long-term daily flow values of the Zamantı River-Değirmenocağı, Zamantı River-Ergenuşağı, and Eğlence River-Eğribük stations in the Seyhan Basin in Turkey were examined. In order to predict the forward flow rate from past flow measurement values, the Adaptative Neuro-Fuzzy Inference System (ANFIS) model was trained using Backpropagation (BP), Hybrid Learning (HB), and Simulated Annealing (SA) algorithms, and the results were compared. The performance of ANFIS models created with different input parameters using Grid Partitioning (GP) and Fuzzy C-Means Clustering (FCM) methods was also examined. The evaluation criteria used for comparison were Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), Determination Coefficient (R2), and Mean Absolute Percentage Error (MAPE). The best results for R2 values of 0.6854, 0.9242, and 0.9373 were obtained for FMSs using the BP model. As a result of the analysis, it was concluded that the BP algorithm could be used more successfully and effectively than other algorithms for training ANFIS parameters in nonlinear problems.

Non-Linear Estimation using the Weighted Average Consensus-Based Unscented Filtering for Various Vehicles Dynamics towards Autonomous Sensorless Design
Authors: Widjiantoro Bambang L. , Wafi Moh Kamalul , Indriawati Katherin
Published: June 2023

The concerns to autonomous vehicles have been becoming more intriguing in coping with the more environmentally dynamics non-linear systems under some constraints and disturbances. These vehicles connect not only to the self-instruments yet to the neighborhoods components, making the diverse interconnected communications which should be handled locally to ease the computation and to fasten the decision. To deal with those interconnected networks, the distributed estimation to reach the untouched states, pursuing sensorless design, is approached, initiated by the construction of the modified pseudo measurement which, due to approximation, led to the weighted average consensus calculation within unscented filtering along with the bounded estimation errors. Moreover, the tested vehicles are also associated to certain robust control scenarios subject to noise and disturbance with some stability analysis to ensure the usage of the proposed estimation algorithm. The numerical instances are presented along with the performances of the control and estimation method. The results affirms the effectiveness of the method with limited error deviation compared to the other centralized and distributed filtering. Beyond these, the further research would be the directed sensorless design and fault-tolerant learning control subject to faults to negate the failures.

Published: June 2023

In the field of wind turbine performance optimization, many techniques are employed to track the maximum power point (MPPT), one of the most commonly used MPPT algorithms is the perturb and observe technique (PO) because of its ease of implementation. However, the main disadvantage of this method is the lack of accuracy due to fluctuations around the maximum power point. In contrast, MPPT control employing neural networks proved to be an effective solution, in terms of accuracy. The contribution of this work is to propose a hybrid maximum power point tracking control using two types of MPPT control: neural network control (NNC) and the perturbation and observe method (PO), thus the PO method can offer better performance. Furthermore, this study aims to provide a comparison of the hybrid method with each algorithm 𝑃𝑂 and NNC. At the resulting duty cycle of the 2 methods, we applied the combination operation. A DC-DC boost converter is subjected to the hybrid MPPT control.  This converter is part of a wind energy conversion system employing a permanent magnet synchronous generator (PMSG). The chain is modeled using MATLAB/Simulink software. The effectiveness of the controller is tested at varying wind speeds. In terms of the Integral time absolute error (ITAE), using the PO technique, the ITAE is 9.72. But, if we apply the suggested technique, it is smaller at 4.55. The corresponding simulation results show that the proposed hybrid method performs best compared to the PO method. Simulation results ensure the performance of the proposed hybrid MPPT control.

Published: June 2023

This paper addresses the problem of obstacle avoidance in mobile robot navigation systems. The navigation system is considered very important because the robot must be able to be controlled from its initial position to its destination without experiencing a collision. The robot must be able to avoid obstacles and arrive at its destination. Several previous studies have focused more on predetermined stationary obstacles. This has resulted in research results being difficult to apply in real environmental conditions, whereas in real conditions, obstacles can be stationary or moving caused by changes in the walking environment. The objective of this study is to address the robot’s navigation behaviors to avoid obstacles. In dealing with complex problems as previously described, a control system is designed using Neuro-Fuzzy so that the robot can avoid obstacles when the robot moves toward the destination. This paper uses ANFIS for obstacle avoidance control. The learning model used is offline learning. Mapping the input and output data is used in the initial step. Then the data is trained to produce a very small error. To support the movement of the robot so that it is more flexible and smoother in avoiding obstacles and can identify objects in real-time, a three wheels omnidirectional robot is used equipped with a stereo vision sensor. The contribution is to advance state of the art in obstacle avoidance for robot navigation systems by exploiting ANFIS with target-and-obstacles detection based on stereo vision sensors. This study tested the proposed control method by using 15 experiments with different obstacle setup positions. These scenarios were chosen to test the ability to avoid moving obstacles that may come from the front, the right, or the left of the robot. The robot moved to the left or right of the obstacles depending on the given Vy speed. After several tests with different obstacle positions, the robot managed to avoid the obstacle when the obstacle distance ranged from 173 – 150 cm with an average speed of Vy 274 mm/s. In the process of avoiding obstacles, the robot still calculates the direction in which the robot is facing the target until the target angle is 0.

Published: June 2023

This research is an attempt to describe students’ learning styles in differentiation learning. The study was conducted on all students of class X-3 at SMAN 8 Malang. Learning style is a consistent way that students have in capturing stimulus or information, how to remember, think, and solve problems. Based on the implementation of the independent curriculum, it is also necessary to map learning needs based on the learning profile of students. This mapping can be done by providing a diagnostic assessment to find out. There are various ways of information processing that students display, some are easier to process through visual information, some are auditory (sound), and others are kinesthetic (direct practice). The findings obtained from this study are that mapping different learning styles can not only improve the quality of learning in students but also help them in mastering mathematics.

Literacy Studies: Implementation of Problem-based Learning Models to Improve Critical Thinking Skills in Elementary School Students
Authors: Smith George , Amirudin Ichda Mochammad , Alfan Muhammad , Kuncoro Tri
Published: June 2023

Students often have difficulty in developing critical thinking skills and creative thinking in problem-solving and applying concepts learned in school. The difficulty is due to weak understanding of concepts, especially for students who are in the low category; therefore, it has an impact on the low-student learning outcomes. One of the reasons for the low-learning outcomes is the difficulty in understanding a concept given by the teacher so students tend to be passive in learning activities, which has an impact on the lack of students to think both critically and creatively in applying the concepts of the material provided by the teacher. The purpose of this study is to conceptually analyze the use of problem-based learning models to improve critical thinking skills in elementary school students. The research method used in this study is a systematic literature study. The author selected 25 articles from journals and articles published during the last 10 years from 2012 to 2022. The results of this review can improve student learning outcomes in elementary schools because this model has characteristics suitable to be applied in real-life situations; in avoiding simple answers, and allowing for multiple solutions to the situation.

Published: June 2023

Öz: Abdullah Bosnevî, tasavvuf alanında olduğu kadar İslam düşünce geleneğinde de önemli bir yere sahip olan İbnü’l-Arabî ekolünün temsilcilerinden biridir. O aynı zamanda İbnü’l-Arabî’nin “Füsûsu’l-Hikem”ini başarılı bir şekilde Türkçe ve Arapça olarak ilk defa şerh eden bir Osmanlı aydınıdır. Bosnevî’nin tefsir ve tasavvuf alanında yazdığı risalelerin çoğu yazma halindedir ve ilim dünyasına tanıtılmayı beklemektedir. Zülkarneyn kıssasını, İslam düşüncesinde etkili olan vahdet-i vücûd nazariyesine göre tefsir ettiği, orijinal yorumları barındıran risalesi de bunlardan biridir. Çalışmada, konu ile alakası ölçüsünde tefsir ve tasavvuf literatürünün incelenmesi, karşılaştırılması ve değerlendirilmesi metodu uygulanmıştır. Müellif hakkında bilgi verildikten sonra, Zülkarneyn kıssası üzerine yapılan zâhirî ve işârî yorumlar incelenmiş, Bosnevî’nin yorumlarıyla kıyaslanmıştır. Müellifin risaledeki tefsir yöntemi üzerinde durulmuş, değerlendirilmiş ve tanıtılmıştır. Müellife ait yorumların işârî tefsir geleneğindeki konumu, tasavvuf ilminin tarihsel aşamaları çerçevesinde ortaya konmaya çalışılmıştır. Risalenin içeriği, konunun işlenişine uygun başlıklar altında tanıtılmıştır. Âyeti âyetle açıklama, siyâk-sibâk ilişkisini gözetme gibi tefsir yöntemlerini kullandığı gözlenen müellifin, zâhirî yorumlarında klasik tefsirlerden yararlanmakla beraber, çok fazla detaya girmediği görülmüştür. İşârî tefsirlerinde ise nazarî-sûfî yorum geleneğine bağlı kaldığı, yüce Allah’ın insanı yaratması ile ilgili ontolojik izahlar yaptığı anlaşılmıştır.

PHOTOCONDUCTIVITY AND PHOTOLUMINESCENCE OF ZnSe:Cr CRYSTALS IN THE VISIBLE SPECTRAL REGION
Authors: Vaksman Yu. F. , Nitsuk Yu. A.
Published: June 2023

The photoconductivity and photoluminescence of ZnSe:Cr crystals in the visible spectra region are studied. The scheme of optical transitions within Cr2+ impurity centers is established. It is shown that the high-temperature impurity photoconductivity of ZnSe:Cr crystals is controlled by optical transitions of electrons from the 5T2(D) ground state to the higher levels of excited states of Cr2+ ions, with subsequent thermal activation of the electrons to the conduction band. Efficient excitation of intracenter luminescence of ZnSe:Cr crystals is attained with light corresponding to the region of impurity absorption.

Authors: Irkha V. I. , Gorbachev V. E. , Vikulin I. M.
Published: June 2023

New effects of modification of spectrum of radiation of light-emitting diode in magnetic field, which give the chance to use a LED as an optoelectronic magnetic field sensor, are discovered. Physical phenomena that appear in light-emitting diodes in a magnetic field are considered. Amplitudemodulated by a magnetic field the optical signal can be obtained if to use a LED with narrow base, where it is possible to gain 50 % magnification of energy of an emission light in a magnetic field. If a LED with long vary-band base is being used as magneto-sensitive element, the magnetic field will shift effective region of recombination to a section with other energy gap, and the LED’s radiated frequency will change. Thus, we obtain a frequency-modulated by a magnetic field optical signal, which is resistant to noises in optical channels. Such detectors of magnetic field are expedient for using in systems with optical processing methods of the information.

Authors: Vaksman Yu. F. , Nitsuk Yu. A. , Korenkova A. V.
Published: June 2023

The photoconductivity and photoluminescence spectra of ZnTe:V crystals in the visible spectral region are studied. It is established that the high-temperature impurity photoconductivity of ZnTe:V crystals is controlled by the optical transitions of electrons from the ground state 4T1(F) to high-energy excited states, with subsequent thermally activated transitions of electrons to the conduction band. A photoconductivity band associated with the photoionization of V impurities is revealed. The intracenter luminescence of ZnTe:V crystals is efficiently excited with light corresponding to the intrinsic absorption region of V2+ ion.

We present new optimal scheme of the separating highly radioactive isotopes and products of atomics energetics such as 210-214Fr, 133,135,137Cs and others, which is based on the selective laser excitation of the isotopes atoms into excited Rydberg states and further autoionization or DC electric field pulse ionization. As result, requirements to energetic of the ionized pulse are decreased at several orders. And an effectiveness of a scheme increases. There are theoretically calculated values of the characteristics of heavy Rydberg atoms in an external electromagnetic field (DC Stark effect) In particular, data on the energy level, the energy widths of Stark resonances for Rydberg Cs, Fr (n <50).

The modern building of the Odessa opera and ballet theatre was built in 1887, and already in 10-15 years there appeared first problems related to its deformation. The two attempts to protect building (strengthening of loess soils (1957) and creation of pile foundation (2005)) were unsuccessful. Every time over the years after realization of projects the deformation started again. The current work provides a model based on micro-block space-dependent geodynamics as a theoretical basis for development of the protection strategy for buildings and constructions on the territory of Odessa from deformations, including the building of the Odessa opera and ballet theatre.
