Application of Low Current Gliding Arc Plasma Discharges for Hydrogen Sulfide Decomposition and Carbon Dioxide Emission Reduction
Authors:   , Nunnally Thomas Patrick , Fridman Alexander A.
Published: July 2024

Presently, hydrogen sulfide decomposition and carbon dioxide emission reduction are among some of the most costly and challenging processes encountered in industry. As a result, the search for efficient, low cost solutions to these processes are often proposed and studied. Unfortunately, very few cost effective solutions have been discovered making implementation at industrial scale very difficult. More recently, the application of low current gliding arc has been proposed as a promising technology for these industrial processes; however poor reactor design and unrealistic gas compositions have ultimately made industrial implementation impossible. In this study, two new, improved types of low current gliding arc, which can operate with realistic mixtures and can be applied at a large scale, are proposed, designed, and characterized. These newly proposed devices are then utilized for hydrogen sulfide and carbon dioxide decomposition. The results of these studies were found to be very promising.

The purpose of this study was to explore social media use and how it can influence programming from the point of view of the user. The case study focused on one example, "The 90s Are All That". This concept was looked at by researching participant engagement and their relationships with the current programming in the retro block. The research was conducted through a survey which also gauged participant social media usage in relation to the programming that they watched. This case study gave insight to the way social media could possibly impact what viewers watch on television based on their preferences.
Actively mode-locked monolithic MQW laser diode integrated with an EA modulator
Authors:   , Lee Joong Hee , Daryoush Afshin S.
Published: July 2024

Active mode locking of semiconductor laser diode is an attractive technique for transmission and signal processing applications because the optical pulse trains are synchronized with an external clock. Analytical investigations are reported for a monolithically integrated electroabsorption (EA) modulator with multiple quantum wells (MQW) laser diode at 1.55 [mu]m. The optical cavity length is 2170 [mu]m corresponding to a natural resonance frequency of ~19.3 GHz. The simulation results are compared with the measurements. The modeling is based on the single mode traveling wave laser diode rate equations. These partial differential equations relate forward and backward moving photon fields to electron density in space and time. The traveling wave rate equations are numerically solved by relating distance and time through group velocity and using the 4th order Runge-Kutta numerical technique. To get the frequency domain mode-locked pulses, a Fast Fourier Transform (FFT) with Taylor data windowing is applied to the time domain simulation results. The optical mode-locked pulses are examined as a function of the EA modulator reverse bias voltage and modulation power. The shortest fullwidth at half maximum power (FWHM) of 7.00 and 7.63 ps are obtained in the measurement and the simulation respectively for the case of gain section bias current of 100 mA, EA modulator reverse bias voltage of -4.5 V, and sinusoidal RF power of 18 dBm at 19.3 GHz. It is also found that the mode-locked pulsewidth is getting broader as the EA modulator reverse bias voltage and the sinusoidal RF power are decreased. This thesis also compares the experimental and analytical results of other mode-locked laser diode dynamic behaviors. The optical spectra is periodic set of pulses instead of Gaussian profile in both cases of measurement and simulation. Coherency measurement and simulation show that the pulse train coherency times are 199 and 210 ps respectively for Ib = 100mA, Vb = -4.5V, and Pm = 15dBm at 19.3 GHz. The power locking ranges of 55 and 75 MHz are obtained for two different cases of I b = 100m. A, Vb = -4.5V, Pm = 18dBm and I b = 140mA, Vb = -4.5V, Pm = 15dBm, respectively. A good agreement in frequency mixing is also observed between measurement and simulation.
Improving everyday action through executive training in schizophrenia
Authors:   , Sestito Nicole , Chute Douglas L.
Published: July 2024

Both everyday action and cognitive functioning are impaired in people with schizophrenia It has been demonstrated that cognitive functioning, and in particular executive functioning, is a strong predictor of everyday action abilities in schizophrenia. Previous research has shown that patients with schizophrenia show a unique performance on the Naturalistic Action Test (NAT), a measure of everyday action, which consisted of a high number of off-task errors consistent with executive dysfunction. Because of the well documented functional impairments seen in everyday tasks in schizophrenia, this study examined whether or not an intervention based on Goal Management Training (GMT) aimed at remediating executive deficits would positively impact everyday action performance in individuals with schizophrenia. The sample consisted of 26 participants with a diagnosis of schizophrenia or schizoaffective disorder who were recruited from inpatient psychiatric units. Three of the individuals originally recruited were unexpectedly released from the hospital before they were able to complete their second session, so their data were not used for the statistical analyses (final n = 23). Overall, our main analyses showed that patients who received the intervention did not show greater overall performance on the NAT, did not commit fewer errors, and did not accomplish more of the steps than patients who received a placebo-control intervention. Effect sizes were also small, further indicating that this patient group did not benefit from the intervention. The hypothesis that GMT would help improve patients' performance on the NAT was not supported. However, it is important to note that while this patient population may be among the most treatment resistant, research shows these patients are capable of improvements in cognition, evidenced by both their behavior and neuronal plasticity. Because of the severe functional impairments present in schizophrenia, future research should continue to investigate different cognitive intervention strategies and their effectiveness.

Published: July 2024

This thesis is a synthesis of digital paleoart reconstruction, prototype VR pipeline design, and the adaptation of structural narrative principles for immersive media. We approach common issues associated with the accurate portrayal of dinosaurs in media, Cinematic Virtual Reality (CVR) production, and the direction of viewer attention in immersive digital environments. After developing and testing a stable CVR workflow, we design and produce a piece of scientific VR Paleoart content intended for educational outreach. Our production methods include a highly detailed CGI dinosaur reconstruction informed by comparative anatomy and biomechanical simulation, stereoscopic spherical rendering, and immersive film production. Our approach is validated through the completion of a CVR documentary about the titanosaur Dreadnoughtus schrani, one of the largest dinosaurs yet discovered. This documentary, starring paleontologist Dr. Ken Lacovara, will be made publicly available for all common VR distribution platforms through a partnership with JauntVR. Our goal is to deliver immersive scientific content to a wide audience of smartphone owners, taking advantage of accessible VR technology to establish new precedents for educational media.
Do problems-solving skills moderate the relationship between stressors and health in women with HIV?
Authors:   , Lombardo Elizabeth Roessler , Nezu Arthur M.
Published: July 2024

Urban women with HIV, the fastest growing subgroup of persons infected with the virus in the United States, potentially face numerous stressors (e.g., health issues, care giving, poverty). The current study sought to examine the relationship between stressors and health, as well as the potentially buffering role of problem-solving skills, within this population. One hundred and twenty-five women participated in a series of self-report questionnaires. Results demonstrated stressors predicted greater negative affect and physical symptoms. In addition, certain aspects of maladaptive problem-solving skills were predictive of greater psychological distress. However, problem-solving skills were not demonstrated to moderate the relationship between stressors and health. Clinical and research implications of the study are discussed.

Authors: Agarkov N. M. , Fabrikantov O. L. , Lev I. V.
Published: July 2024

For the prevention of diabetic retinopathy, it is important to study risk factors, among which, along with the duration of type 2 diabetes mellitus, the level of glycemia, obesity, chronological age is indicated, but biological age is not considered as a potential risk factor, although biological age more objectively than chronological characterizes pathological changes at the cellular level and processes apoptosis. Purpose: to study biological age as a new risk factor for diabetic retinopathy in patients with type 2 diabetes mellitus. 580 patients aged 45–59 years with diabetic retinopathy and type 2 diabetes mellitus, whose biological age was calculated according to the Voitenko V.P. et al. methodology, took part in the study on the basis of the S.N. Fedorov National medical research center “MNTK Eye Microsurgery”. The correspondence of biological and chronological age was established in 124 patients, the excess (acceleration) of the chronological biological age in 357 patients and the excess of the biological chronological age in 99 patients. In the subsequent analysis, the first two groups were considered. Among 45–59­year­old patients with type 2 diabetes mellitus, the incidence of diabetic retinopathy was 19.82 ± 1,32 cases per 100 examined, which is statistically significantly higher (p < 0.001) compared to patients of the same age with type 2 diabetes mellitus with a chronological biological age — 10.24 ± 1.51 cases per 100 examined. Significant differences in the compared groups were also revealed in the values of the chronological age of diagnosis of diabetic retinopathy in this endocrine disease — 47.69 ± 1.24 years in patients with accelerated biological age and 50.23 ± 0.92 years in patients with matching biological and chronological age (p < 0.01). The biological age of diagnosis of diabetic retinopathy, respectively, was 56.13 ± 0.83 years and 49.61 ± 1.11 years (p < 0.001). The difference in the development of diabetic retinopathy in patients 45–59 years old with type 2 diabetes mellitus by biological age was 6,52 ± 1,24 years among patients with accelerated biological age and 0.62 ± 0.09 years among patients with matching biological and chronological age (p < 0.001). Consequently, the acceleration of biological age is a significant and new risk factor for diabetic retinopathy in patients aged 45–59 years with type 2 diabetes mellitus.

The cytokine profile of primary coronary artery endothelial cells cultivated in the presence of doxorubicin (2 μg/ml and 6 μg/ml) was evaluated using enzyme-linked immunosorbent assay and qPCR. Cultivation of cells in the presence of these concentrations of doxorubicin for 24 h, upregulated expression of the following genes: IL6 (by 2.30 and 2.66 times, respectively), IL1B (by 1.25 and 3.44 times), and CXCL8 (by 6.47 times and 6.42 times), MIF (2.34 and 2.28 times), CCL2 (4.22 and 3.98 times). Under these conditions the following genes were downregulated: IL10, IL1R2, TNF. Cultivation of cells in the presence of doxorubicin (2 μg/ml and 6 μg/ml) for 24 h also increased the secretion of IL-6.
Computational Identification of Ovarian Cancer Candidate Driver Genes with Mutated Protein Structures Caused by Missense Variants
Authors: Hou Ian , Bai Yongsheng
Published: June 2024

Ovarian cancer detection remains elusive due to a lack of screening tests and non-specific symptoms. A crucial factor in cancer development is DNA sequence mutations, particularly missense mutations that can alter protein structure, thereby potentially initiating carcinogenesis. Advances in sequencing technology have paved the way for detailed analysis of individual genetic profiles, spotlighting genes with missense mutations as prospective biomarkers. Such biomarkers are pivotal for personalizing cancer therapies, as they can guide medication choices, ensuring efficacy and minimizing detrimental effects. Despite tools like AlphaFold predicting 3D protein structures and Phyre2 assessing mutated amino acid impacts, no model concurrently predicts wild-type and mutated protein structures. Also, integrating structure changes with drug target identification remains under-explored. Analyzing the TCGA Ovarian Cancer transcriptome data, this research postulated that missense mutations in highly expressed genes significantly influence protein structure, earmarking these genes as potential therapeutic targets. Twelve genes were discerned to affect ovarian cancer patient survival rates. An original platform, MiSeVis, was introduced, offering insights into potential drug targets for specific genes, survival analysis, and 3D protein structure alterations. This comprehensive methodology, unifying transcriptome analysis, pinpointing genes with impactful missense mutations, and presenting a user-centric visualization tool, marks considerable progress in ovarian cancer treatment and precision medicine.

Authors: Keleş Emine
Published: June 2024

Riparian vegetation, as an integral part of river systems, provides various socio-ecological functions by strengthening the link between aquatic and terrestrial ecosystems. They provide comprehensive ecosystem services in physical, chemical, biological and social terms, establishing a critical link between humans and the environment. This study highlights the growing importance of riverine riparian vegetation and ecosystem services through a bibliometric analysis of scientific publications between 2000 and 2023. In the 494 publications analyzed in the study, 72% regulating (water quality, erosion prevention, climate regulation) and 43% supporting (habitat provision) ecosystem services were predominantly evaluated, while provisioning and cultural services were not sufficiently addressed. In addition, although various methods such as statistical analysis, GIS and model-based approaches were used in the reviewed studies, the lack of standardized assessment methods was identified. In conclusion, this study highlights the gaps in informed decision-making and planning in riparian areas. It emphasizes that protecting, managing and restoring riparian vegetation is critical for the sustainability of water resources, biodiversity, human well-being and overall ecosystem health.

Authors: Parveen Shana , Kanthi Janu M. , Bhaskaran Renjitha
Published: June 2024

Background: Premenstrual syndrome (PMS) is a set of distressing physical and psychological symptoms occurring cyclically during the luteal phase of each menstrual cycle that begin a few days before menstruation and resolves within a few days of the onset of menstruation. This study focuses on finding the prevalence of premenstrual symptoms among university students and also to assess the socio-demographic, dietary and lifestyle factors associated with premenstrual symptoms.
Methods: An institutional based cross-sectional study was conducted were participants were asked to fill a premenstrual syndrome scale (PMSS) questionnaire based on which they were categorised as ‘positive PMS’ or ‘negative PMS’. Any coping mechanism applied were also reported.
Results: A total of 202 participants were part of the study of which 137 (67.8%) of them had premenstrual symptoms and of which 49 (79%) of them had a familial history of PMS. Menstrual related factors like familial history of PMS, perceived menstrual pain intensity, quantity of menstrual bleed, Duration of symptoms in the premenstrual periods were found to be significantly associated with PMS. Mood swings, abdominal cramps and generalised aches and pains were predominant symptoms reported by the students. Taking rest, sleeping and listening to music were the commonly applied coping mechanisms to relieve the symptoms.
Conclusions: The prevalence of PMS is on the higher side i.e. 68.3% compared to many studies around the world. The health seeking behaviour knowledge about PMS seems to be quite low among the students and thereby indicates the need to provide awareness and give emphasis on the management of premenstrual symptoms both pharmacologically (if required) and non-pharmacologically.
A rare case of congenital methemoglobinemia in pregnancy
Authors: Rajmane Shantanu H. , Anand Mamta Neelesh , Senapati J. B.
Published: June 2024

When iron in haemoglobin is replaced from Fe+2 (ferrous) to Fe+3 (ferric), it leads to formation of methemoglobin. Normal levels of methemoglobin are <1%. This is maintained by redox balance between activity of NADH methemoglobin reductase enzyme and amount of oxidised hemoglobin. When levels of methemoglobin are increased, it leads to methemoglobinemia. Methemoglobin has less affinity to bind to oxygen & results in left shift of oxygen–hemoglobin dissociation curve. As most of the cases of congenital methemoglobinemia are asymptomatic, it is often diagnosed first time during pregnancy. Here we report a case, Primigravida with 38 weeks of gestation posted for emergency LSCS i/v/o meconium-stained liquor, who had SPO2 of 84%, was clinically asymptomatic, vitally stable and with ABG, CXR, ECG and 2DECHO normal. Efforts to find out the cause of reduced oxygen saturation led to diagnosis of rare hemoglobinopathy, methemoglobinemia.

Authors: Duwal Santosh , Manandhar Kishor
Published: June 2024

Background: The surgical history of inguinal hernia dates back to Egypt, from Bassini’s repair to today’s mesh based open and laparoscopic repair. Still superiority of laparoscopic over open repair is controversial. However laparoscopic technique was reported to be better in term of post-operative pain and early return to work.
Methods: A prospective cross-sectional observational study was performed in Bir Hospital from August 2020 to January 2021. Sample size was 56. Hospital ethical committee approval and written informed consent from patients was obtained. Convenient sampling was done and data analyzed with SPSS ver. 23 and Microsoft excel 2010.
Results: 26 patients each were allotted to two group: laparoscopic hernia (LH) and open hernia (OH). The mean age was 50.50±17.20 years. LH group had significantly less postoperative pain than the OH group on 12, 24 and 48 hours (p<0.05). Although the vas pain scores of LH group were also comparatively lower on 0 hour, these differences were not statistically significant. The mean hospital stay after surgery was less for LH group (2.14±0.356 vs 2.43±0.356) but was not statistically significant. (p=0.286). Although more post-operative complications were seen in OH group, these were not statistically significant (p values for wound infection 0.491, for scrotal swelling 0.193). LH group had significant early return to work than OH group (13.32±2.109 vs 21.21±5.354 days) with p value 0.000.
Conclusions: Laparoscopic inguinal hernia repair is better than open inguinal hernia repair in terms of less post-operative pain and early return to work.

Authors: Sharma D. J. , Singh Ravinder , Bahl Ina , Singh Gurjot
Published: June 2024

Background: The lifetime risk of diabetic foot ulcer (DFU) may be as high as 25%. The primary aim in a case of DFU is to obtain wound closure as expeditiously as possible. Hydrosurgery debridement is a recent and new novel approach for debridement.
Methods: The study was an observational prospective comparative study between hydrosurgery system and surgical debridement for assessment of hydrosurgery as a tool for debridement of DFUs carried out at tertiary care centre on patients presenting to or referred to the hospital. Study was being conducted on 60 patients of diabetic foot disease. They were divided into two groups of 30 each. Randomization was done by computer generated numbers.
Results: Mean diabetes duration was lower in hydrosurgery group as compared to surgical debridement group (11.53 and 14.63 years respectively). Deformity was present in 43.3% and 33.3% of patients in hydrosurgery and surgical debridement groups respectively. On culture sensitivity of tissue/pus, Klebsiella (23.3%) was dominantly found in hydrosurgery group whereas Klebsiella and Pseudomonas were found equally in Surgical debridement group (20% each). Mean operative time was less in hydrosurgery group as compared to Surgical debridement (15.30 and 23.67 minutes respectively).
Conclusions: Hydrosurgery system showed significant advantages over standard surgical scalpel debridement with lesser debridements required, reduced operative time and in hospital stay. It permitted adequate debridement of the diabetic foot wounds without much collateral damage which usually happens with standard scalpel debridement, preserving more viable tissues to promote rapid healing.

Authors: Brahmbhatt Rutu A. , Patel Drupad G. , Chaudhary Pranav B.
Published: June 2024

Intussusception occurs when one portion of the bowel invaginates into an immediately adjacent segment, almost invariably it is the proximal into the distal. Duodenoduodenal intussusception is a rare condition that is in general caused by a tumour either benign or malignant. However duodenal intussusception is an extremely rare entity as duodenum is a fixed retroperitoneal structure. The lead point of intussusception is usually a Meckels’s diverticulum, a Peutz-Jeghers polyp or intestinal adenomas. We describe two case reports of duodenoduodenal intussusception secondary to a tubulovillous adenoma and juvenile hamartomatous polyp ((Peutz Jegher’s polyposis) that caused intussusception in a 17-year-old female and 11-year-old male respectively. Both cases had underlying abnormalities acting as lead points with different etiologies. We resected the tumour mass from both patients successfully. This report describes the rare case of isolated adenoma of the 3rd part of the duodenum and Peutz Jegher polyp in the jejunum presented as duodenoduodenal and duodenojejunal type of enteroenteric intussusception fully treated by segmental resection of the duodenum and jejunum and doing well on follow up.

Published: June 2024

Women are generally more compliant with tax obligations than men, often paying taxes more diligently and on time. A field experiment found that deterrence letters prompt women to pay earlier but do not necessarily increase overall compliance. In contrast, men show marked improvement in overall compliance upon receiving such letters. The size of the tax bill significantly influences womens compliance behavior, with a greater likelihood of paying smaller bills, indicating potential liquidity constraints.

Intertextualidad y literatura infantil. El diálogo entre textos en el estudio del álbum ilustrado
Authors: Vouillamoz-Pajaro Núria
Published: June 2024

Una revisión crítica del concepto de “intertextualidad” permite ampliar la mirada sobre las asociaciones dialógicas que los textos literarios establecen entre sí. Más allá de las citas o las referencias textuales, las obras se interrelacionan a nivel discursivo, formal y temático, compartiendo rasgos de género, técnicas constructivas y temas que permiten concebir la literatura como una red infinita de conexiones. Esos vínculos deben ser explorados desde la literatura comparada que, como disciplina, proporciona una metodología contrastiva capaz de aproximarse a los textos desde su trascendencia intertextual. Este artículo aborda la traslación de la teoría de la intertextualidad y la literatura comparada al ámbito de la literatura infantil y juvenil, con el objetivo de emprender un estudio del álbum ilustrado. Desde esos parámetros, se ha construido un modelo de análisis diseñado en base a los nexos discursivos, morfológicos y tematológicos que ponen en relación unas obras con otras. La aplicación de ese modelo arroja nueva luz no solo sobre el examen crítico de los textos, sino también sobre los efectos didácticos, porque una “lectura en red” reta al lector a asumir nuevos aprendizajes y a desarrollar habilidades que vienen a enriquecer su formación literaria.

The Role of Mesenchymal Stem Cells in Dentistry: A Review
Authors: A. Kurmanalina Madina , M. Urazalina Marina , A. Abasheva Gulshara , M. Aitmukhanbetova Aruzhan
Published: June 2024

Mesenchymal stem cells (MSCs) have garnered significant attention in regenerative dentistry due to their remarkable ability to differentiate into various cell types and their immunomodulatory properties. This review provides a comprehensive overview of recent advancements in MSC research relevant to dentistry, focusing on their potential applications in periodontal tissue regeneration, dental pulp regeneration, and maxillofacial bone repair. Periodontal diseases, which affect the tissues surrounding and supporting the teeth, are a significant challenge in dentistry. Current treatments often involve surgical intervention and tissue grafting. MSCs have shown promise as a potential alternative for periodontal tissue regeneration, as they can differentiate into periodontal ligament cells, cementoblasts, and osteoblasts. Several preclinical and clinical studies have demonstrated the efficacy of MSC-based therapies in periodontal regeneration. Dental pulp regeneration is another area where MSCs hold promise. Damaged or infected dental pulp can lead to pulpitis or pulp necrosis, necessitating root canal treatment. MSCs have been studied for their ability to regenerate dental pulp tissue and promote pulp healing. They can differentiate into odontoblast-like cells and regenerate dentin-like tissue, making them a potential treatment option for dental pulp regeneration. In maxillofacial bone repair, MSCs have been investigated for their osteogenic differentiation potential and ability to stimulate bone regeneration. Studies have shown promising results, suggesting that MSC-based therapies could be a viable treatment option for maxillofacial bone defects. The mechanisms underlying MSC-based therapies in dentistry are not fully understood but are thought to involve a combination of paracrine effects, immunomodulation, and differentiation into specific cell types. Future research should focus on addressing these challenges and exploring novel approaches for enhancing the regenerative potential of MSCs in dentistry.

Objective To compare the results of the lateral internal sphincterotomy(LIS) technique and high dose botulinum toxin, which is one of the treatments applied when medical treatment is insufficient in anal fissure. Materials and methods The files and outpatient clinic notes of the patients who underwent lateral internal sphincterotomy and botulinum toxin injection due to lack of response to medical treatment due to anal fissure between May 2020 and May 2023 were examined retrospectively. Preoperative and postoperative visual analog scale (VAS) scores, five-point horizontal scale (FPHS) scores, hospitalization times, fissure locations, follow-up periods, anesthesia type, and postoperative complications of the patients were recorded. Results Total 30 LIS and 24 botulinum toxin-treated patients were included. Hospitalization time was shorter in botulinum toxin groups than in the LIS group (p<0.001). First-week VAS score was lower than botulinum toxin injection group (p<0.001). There was no significant difference between the groups in terms of FPHS scores, follow-up periods, and recurrence (p:0.15, p:0.07, p:0.14). Conclusion: While LIS is faster in the early period, botulinum toxin injection can be considered as an alternative to surgical treatment for long-term results.
Herman Melville y Manuela Sáenz: historia de un encuentro incomprobable
Authors: Ramírez Roberto
Published: June 2024

Resumen: Biografías, periódicos y artículos académicos aseveran que el escritor estadounidense Herman Melville y la prócer de las independencias Manuela Sáenz, a mediados del siglo XIX, en Paita, Perú, se entrevistaron, a propósito del exilio que ella atravesaba y el viaje que él hacía por los mares del mundo (1841-1844), a bordo del Acushnet y el United States. Nadie da fuentes que corroboren este encuentro que pasa por Historia oficial. Es así como este ensayo expone el detallado paso de Melville por Latinoamérica para demostrar que no hay pruebas de que los dos coincidieran; además, se señala a la biografía de Victor Wolfgang von Hagen como la fuente que inició dicho rumor y las razones que tuvo para hacerlo. Concluye el ensayo con las implicaciones de este hecho supuestamente histórico en su salto a la ficción, con un recuento de obras literarias y cinematográficas que recogen el encuentro.

The popularity of econometric analyses that include variables obtained from text mining is growing rapidly. A frequently applied approach is to identify topics from large corpora, which makes it possible to determine trends that reflect the changing relevance of topics over time. We address the question of whether such topic trends are linked to quantitative economic indicators typically used for analysing the objects described by a topic. The analysis is based on academic economic articles from Poland and Germany from 1984 to 2020. There is a specific focus on whether relationships between topic trends and indicators are similar across national economies. The connection between topic trends and indicators is analysed using vector autoregressive models and Granger causality tests.

Relevance. Pipeline transportation of oil and oil products is one of the most efficient and cost-effective modes of transport in the modern world. Despite this, this type of transport can also be environmentally hazardous in case of leakages caused, for example, by corrosion, violation of operating rules, unauthorized tie-ins. Non-operational localization and liquidation of leakages and unauthorized tie-ins is often not only the cause of significant financial losses, but also accidents and pollution of the area of varying severity and scale. Nowadays, the issue of determining the leakage that has occurred and its location in the shortest possible time remains open. In this regard, the development of new and improvement of existing methods for detecting leakages and tie-ins in pipelines is an urgent task today. Aim. To study the effect of the total head shift, which occurs when taking into account the change in the power of pumping units due to product leakage, on the accuracy of determining the localization of leakage or unauthorized tie-in; to improve the existing methods for determining the leakage coordinate taking into account the change in the total head developed by the oil pumping station. Methods. Modeling the occurrence of a leakage or unauthorized tie-in with a different percentage of product losses, constructing hydraulic slope lines with leakages of varying intensity in different coordinates, a comparative analysis of the results obtained from the considered existing methods and those proposed by the authors. Results. The authors have modeled the leakages in various coordinates and determined the possibility of the proposed method operation for finding the coordinates of leakages. They calculated as well the errors in determining the location of the tie-in or leakage, depending on the pump power drops when the product flows out of the oil pipeline. The paper introduces the formula for the localization of leakages or tie-ins, considering the change in the power of pumping units and, as a result, the total head.

Relevance. Recently, ESG (Environment, Social, Governance) principles have been given an important role in the agenda of oil and gas companies – this is an actively developing global trend in the modern business environment. One of its key aspects is a responsible attitude to the environment, increasing the priority of solving environmental problems arising from the extraction of hydrocarbons. A significant environmental problem is, in particular, pollution of freshwater horizons during oil production due to their poor-quality insulation during well cementing. At the same time, in the space of the well behind the casing, there is a flow of borehole fluid to freshwater horizons, which has a negative impact on the environmental situation in this region. In this regard, monitoring the technical condition of wells crossing freshwater horizons is an important and urgent task. Object. An operational well drilled through freshwater horizon, in which geophysical studies are carried out by the method of active thermometry – local heating of the casing section is carried out and the dynamics of the temperature field in it is studied. Aim. To identify qualitative patterns and obtain quantitative estimates of the effect of the fluid flow in the space behind the casing (column space) on the temperature field in the casing. Methods. Numerical mathematical modeling of thermal and hydrodynamic processes in a well using the software package Ansys Fluent (ANSYS Academic Research CFD license, agreement with Bashkir State University dated 06/15/2020). Results. The authors have studied the influence of a plane-parallel horizontal fluid flow of the freshwater horizon on the azimuthal temperature distribution of the casing string during induction heating. It is shown that in the case of leakiness of the cement ring in the interval of the freshwater horizon, an inhomogeneity of the azimuthal temperature distribution of the column is observed, reaching a value of few more K. The authors carried out the simulation of induction heating in the well with liquid column flow to the interval of the freshwater horizon. It is shown that the sign indicating the overflow is the occurrence of a temperature disturbance area vertically above the induction heating interval with a length of more than 1 m. In general, the results of the performed studies show the informativeness of the active thermometry method in relation to the diagnosis of the technical condition of wells drilled through freshwater horizons.

Relevance. The need to study the elemental composition of the organism of wild and domestic animals in natural environments with different levels of chemical elements. Aim. To reveal features of the elemental composition of the organism of the Altai red deer (Cervus elaphus sibiricus Severtzov, 1873), wild boar (Sus scrofa scrofa Linnaeus, 1758) and domestic pigs (Sus scrofa domesticus Erxleben, 1777) in Ongudai district, Altai Republic, including the area with signs of active geophagy. Objects. Organs and tissues of wild and domestic animals. Methods. Mass spectrometry with inductively coupled plasma; atomic-emission spectrometry; ion chromatography, analytical electron microscope with energy dispersion spectrometer. Results. The median values of chemical elements concentrations in the organisms of the Altai red deer, the wild boar and the domestic pig have been determined. S, Cl and K showed the highest values in the composition of macroelements and La, Ce, Nd and Th among rare-earth and radioactive elements. Among the elemental composition features of the studied animals, an increased accumulation of Hg and Pb in the Altai red deer; metals of the Fe-group, W, as well as rare-earth and radioactive elements – in the boar; platinoids – in the domestic pig. In comparison with the results of previous studies, increased concentrations of Hg in red deer kidneys, W in boar bronchi and Pb in the brain of domestic pigs were recorded. Assumptions were made about the factors influencing the formation of the elemental composition of the body of animals. For red deer and wild boar these are the factors of nutrition (including geophagy) and features of accumulation of elements in bone tissue; for domestic pigs – features of forage and local metallogeny, including composition of natural waters.
