Authors: Ravelev K. A. , Vyatkin K. A. , Ilyushin P. Yu.
Published: December 2021

Background. Hydrochloric acid treatment is currently one of the main methods used for recovering and improving the reservoir properties of bottom-hole formation zones. In the process of acid treatment, during the reaction of the acid composition and the rock, highly conductive filtration channels are formed. The structure and shape of such channels characterise the treatment efficiency. As a result, much research attention is currently paid to predicting the formation of filtration channels and changes in the filtration characteristics of reservoirs with different properties and types of pore space.Aim. To study the factors that directly affect the formation of dissolution channels in core samples when simulating hydrochloric acid treatment of the bottom-hole zone of carbonate reservoirs on a filtration unit. The main objectives are to determine the significance of these factors and to establish dependencies reflecting their effect on the efficiency of technologies aimed at stimulating oil inflow.Materials and methods. We used the results of filtration and X-ray tomographic studies on core samples taken from the scientific base of the “Geology and Development of Oil and Gas Fields” Scientific and Educational Centre. The collection of rock samples is represented by various deposits confined to the oil and gas complexes of the Perm Territory.Results. The conducted analysis allowed us to identify the effect of various factors on the formation of highly conductive filtration channels during acid treatment. These factors were found to include the lithological and mineralogical composition and initial filtration parameters of core samples, as well as the type of pore structure. Dependences that characterise the efficiency of acid treatment were determined.Conclusions. The obtained results can be used when developing measures for the intensification of oil production, taking into account the revealed factors.

Published: December 2021

Background. In the Russian Federation, as well as in many other oil and gas producing countries, waterflooding technology is frequently used as a secondary method of oil production. This technology is aimed, on the one hand, at reservoir pressure maintenance (RPM), and, on the other, at enhancing oil recovery and intensifying oil production. The negative consequences of non-stationary waterflooding can be the premature watering of the produced wells and the imbalance of the reservoir pressure maintenance system, as well as the formation of stagnant and weakly drained zones of the reservoir with residual reserves of hard-to-recover oil.Aim. To improve the efficiency of non-stationary waterflooding under the conditions of high geological and anthropogenic heterogeneity of oil and gas reservoirs in a floating oil reservoir propped up by edge and bottom waters.Materials and methods. We used geological and field information collected on the site of the AB1-2 development object of the Kechimovskoye field in the Western Siberian region. A new methodological approach to optimizing the process of non-stationary waterflooding under complicated conditions of geological and anthropogenic heterogeneity is proposed, including the construction of an improved geological model and the solution of a number of experimental problems using the Hurst method, the Pareto distribution principle and the theory of catastrophes.Results. Using a new version of the geological model of the area of the AB1-2 development object of the Kechimovskoye field and the available geological and field information, we clarified the position of the oil-water contact (OWC) and the correlation of the well section, taking into account the working intervals of production and injection wells. Geological and technical measures were formulated to improve the efficiency of the object under development.Conclusions. An effective development of the geologically complex AB1-2object of the Kechimovskoye field is impossible without updating its geological model. Such updating should be aimed at determining the location of residual reserves in the area and section of the reservoirs, identifying the regularities of the mechanism of oil reserve recovery, assessing the efficiency of the reservoir pressure maintenance system, and developing complex geological-technological measures for achieving the approved value of the final oil recovery factor. The expected efficiency of the proposed optimization methodology provides for additional oil production, a reduction in the flow rate of injected and withdrawal of produced water.
Utilidad del estudio de la actividad antibiótica mediante bioensayo en el manejo de la infección del tracto urinario en pacientes pediátricos
Authors: Rubio Sánchez Ricardo , Lepe-Balsalobre Esperanza
Published: December 2021

La infección del tracto urinario es la infección bacteriana no respiratoria más frecuente en pediatría. El objetivo de este estudio fue determinar la presencia de actividad antibiótica en muestras de orina y evaluar su posible influencia en el manejo clínico de los pacientes pediátricos. Se incluyeron 138 pacientes con sospecha clínica de infección del tracto urinario. Hubo uso previo de antibióticos en 30 muestras de orina, pero sólo en 18 de estas muestras se encontró actividad antibiótica mediante bioensayo. Este estudio muestra un alto porcentaje de pacientes pediátricos con uso de antibióticos antes de la recolección de la orina. Los parámetros bioquímicos de la orina, como la presencia de más de 25 leucocitos por campo o nitritos positivos, deben alertarnos sobre la posibilidad de una infección bacteriana. La evaluación de la actividad antibiótica en la orina de pacientes pediátricos, junto con el cultivo microbiológico y los parámetros bioquímicos, permite optimizar el tratamiento antibiótico.

Authors: Cuenca María Blanca , García-Martín María Belén , Calero García María José
Published: December 2021

La enfermería está expuesta a una variedad de estrés laboral afectando a su salud mental y productividad laboral. Se ha demostrado que la flexibilidad psicológica tiene beneficios para la salud mental de la población general. Los objetivos de este estudio fueron analizar en el personal de enfermería la relación entre estresores laborales y flexibilidad psicológica; entre sintomatología emocional y flexibilidad psicológica; y las diferencias en la exposición a estresores y en la sintomatología emocional de la enfermería entre diferentes áreas de trabajo y turnos. En este estudio correlacional comparativo se usaron los cuestionarios NSS, DASS-21 y AAQ-II. La prevalencia de niveles de moderado-a muy severo de depresión, ansiedad y estrés fueron 17.6%, 29.9% y 23.3%, respectivamente. Se observó una correlación significativa negativa entre los estresores laborales y la flexibilidad psicológica; entre el estrés laboral y flexibilidad psicológica; entre sintomatología emocional y flexibilidad psicológica; entre ansiedad, estrés y la edad; y entre los estresores laborales y la edad. Las enfermeras que trabajaban con turnos rotatorios declararon niveles significativamente mayores de sintomatología emocional, estrés y ansiedad que las que trabajaban en turnos diurnos. La flexibilidad psicológica parece explicar una prevalencia significativa de sintomatología emocional en enfermería. Las enfermeras comunitarias mostraron los niveles más bajos de ansiedad, depresión y estrés en comparación con las enfermeras de hospital.

Circadian Liver Metabolism Affects Management of Type 2 Diabetes Mellitus During Cytokine Storm Due to COVID-19
Authors: Kumar Dipak , Jahan Sadaf
Published: December 2021

Diabetes is managed to keep the blood sugar in normal range. This involves liver as glucose metabolizing organ and sensitization of somatic cells to utilize this glucose for daily energy requirements. The management is subjected to the rhythmic glucose intake as diet and liver circadian cycles that runs parallel to this zeitgeber. COVID-19 patients having diabetes as comorbid condition face the challenges of inflammatory cytokine management along with the organization of glucose. Increased blood glucose level during the cytokine storm further aggravates the pathophysiology of COVID-19 patients leading to high morbidity and mortality in such patients. Clinical treatment of these patients requires multidimensional approach involving circadian variation of hepatic physiology, glucose intake, and inflammatory cytokine release.

Architectural Travelers: The Role of Field Trips in Spatial Design Education
Authors: Kesim Berk , Baturayoğlu Yöney Nilüfer
Published: December 2021

Architectural design and its education are physio- and socio-spatial activities. In other words, creating space is concerned with understanding the physical as well as the social/cultural context to produce meaning and values beyond determining and answering the right questions. Informal learning environments have always been an integral part of the profession even before its formal definition. Experiential learning or field trips play a significant role in architectural and spatial design education, yet procedural aspects of designing such a journey have not been discussed by educators regarding active and informal learning. This paper aims to understand the role of field trips and re-discover how they contribute to spatial design education at undergraduate level through the processes of learning by doing and research by design / design by research. The field trips, or the context, are discussed with a three-fold focus as an interdisciplinary design process: (1) Understanding the study field from macro to micro scale; (2) Experiencing and observing the society, culture and daily life; (3) Comparative studies through visits to buildings with similar programs. Case studies with local, national and international/foreign contexts from design studios of primary and secondary cycles are presented in order to illustrate this process.
Rate Effects on Peak and Residual Strengths of Overconsolidated Clay in Ring Shear Tests
Authors: Duong Nguyen Thanh , Suzuki Motoyuki
Published: December 2021

Overconsolidated (OC) clay soil is widely distributed in landslide slopes. This soil is often fissured, jointed, contains slickensides, and is prone to sliding. Thus, the shear strength behavior of OC clayey soil is complicated and has received much attention in the literature and in practice in terms of evaluating and predicting landslide stability. However, the behavior of the shear strength of OC clayey soil at different shear rates, as seen in ring shear tests, is still only understood to a limited extent and should be examined further, especially in terms of the residual strength characteristics. In this study, a number of ring shear tests were conducted on kaolin clay at overconsolidation ratios (OCRs) ranging from 1 to 6 under different shear displacement rates in the wide range of 0.02 mm/min to 20.0 mm/min to investigate the shear behavior and rate dependency of the shear strength of OC clay. Variations in the cohesion and friction angles of OC clay under different shear rates were also examined. The results indicated that the rate effects on the peak strength of OC and normally consolidated (NC) clays are opposite at fast shear displacement rates. At the residual state, as with NC clay, the positive rate effect on the residual strength is also exhibited in OC clay, but at a lower magnitude. Regarding the shear strength parameters, the variations in the cohesion and friction angles of OC clay at different shear rates were found to be different at peak and residual states.

In this paper, an improved Backstepping control based on a recent optimization method called Ant Lion Optimizer (ALO) algorithm for a Doubly Fed Induction Generator (DFIG) driven by a wind turbine is designed and presented. ALO algorithm is applied for obtaining optimum Backstepping control (BCS) parameters that are able to make the drive more robust with a faster dynamic response, higher accuracy and steady performance. The fitness function of the ALO algorithm to be minimized is designed using some indexes criterion like Integral Time Absolute Error (ITAE) and Integral Time Square Error (ITSE). Simulation tests are carried out in MATLAB/Simulink environment to validate the effectiveness of the proposed BCS-ALO and compared to the conventional BCS control. The results prove that the objectives of this paper were accomplished in terms of robustness, better dynamic efficiency, reduced harmonic distortion, minimization of stator powers ripples and performing well in solving the problem of uncertainty of the model parameter.

‘Gender Activists Will Kidnap Your Kids’: The Construction of Feminist and LGBT+ Rights Activists as Modern Folk Devils in Czech Anti-Gender Campaigns
Authors: Svatoňová Eva
Published: December 2021

This chapter examines how internet forums such as Facebook can be used in creating and spreading misleading stories and stimulating fear and panic. With the example of the Czech society, the author analyses various web forums that are based on anti-LGBT rights and anti-feminist ideologies, promoting these as threats to nuclear families and traditional gender norms. The text shows the paradoxical portrayal of LGBT activists as, on the one hand, freaks living on the fringe of society, not much more than a laughing stock, and, on the other hand, as a threat with the potential power to destroy traditional values in Czech society.

Summary. Distal mandibular aspects, especially in conditions of atrophy of the alveolar processes, are traditionally considered unfavorable for dental implantation, which is primarily due to unsatisfactory anatomical and topographic peculiarities (proximity of the inferior alveolar nerve, presence of the mandibular fossa) and require on the pre-implant preparation stage a row of additional surgical procedures aimed on increasing of bone volume or an employment of alternative implantation techniques. Aim – summarizing of own experience of placement of lateral (disc) implants in cases of severe distal mandibular atrophy. Materials and methods. 10 patients (men – 3, women– 7) with uni-, bilateral free-end defects or total mandibular adentia were examined and treated. 22 lateral (disc) implants BOI® (Ihde Dental AG, Switzerland) were installed in combination with 1-stage screwable compression implants KOS®, TPG® Uno (Ihde Dental AG, Switzerland) and loaded immediately within 3–4 days. Results. On the control clinical and roengenological inspections 6-9 mo post-op 20 (90.9 %) of 22 installed lateral (disc) were stable, painless at percussion, with absence of evident inflammation around them, demonstrating the signs of osteointegration. There was no one case of complications due to direct mechanical damage of mandibular canal walls by disc components of the implants. Conclusions. Placement of lateral (disc) implants in distal mandibular aspects creates a serious alternative to generally recognized techniques of pre-implant surgery, allows to provide a functional status of dento-maxillary system in shortest terms owing to realization of their immediate loading protocol. Key words: distal mandibular aspects, atrophy of the alveolar process, pre-prosthetic preparation, lateral (disc) implantation.

According to several studies, women with Crohn's disease (CD) had reduced fertility, which is mostly due to voluntary decisions and reduced ovarian reserve. In our study, we aimed to compare reproductive health parameters (RHP), previous pregnancy complications and outcomes, and ovarian reserve (OR) assessed by the anti-Mullerian hormone (AMH) in CD patients with healthy controls. In CD patients, we also compared OR according to disease phenotypes. Consecutive pre-menopausal women with CD from two IBD centers were included. The control group consisted of age and BMI-matched healthy controls. We used a questionnaire that included RHP, CD phenotype, and CD activity. Serum AMH was assessed by the Elecsys AMH plus essay. We enrolled 50 patients and 56 controls with a median age of 31 years. All CD patients were in clinical remission. We observed no difference in RHP or AMH (median 2.6 vs. 2.1 ug/l,
p = 0.98), or the proportion of low OR (AMH<1,77, 38 vs. 41.1 %, p=0.84). The slope of age-related decrease did not differ between the groups. The subgroup of CD patients after surgery and those older than 30 years with CD for >5years had a steeper decrease in AMH (slope -0.12 vs. -0.29, p = 0.04 and -0.31 vs. -0.2, p = 0.029). In a multivariate analysis, age was the single independent predictor of low OR (OR=1.25). In women with Crohn’s disease, once the disease activity is under control, the reproductive health and ovarian reserve do not substantially differ from healthy controls.

Since 2015, more than 560,000 South Sudanese primary school children have received psychosocial support (PSS) through the USAID-funded Integrated Essential Emergency Education Services program implemented by UNICEF. Several South Sudan-based nongovernmental organizations partnered with UNICEF to train local teachers to implement the PSS activities in child-friendly spaces. To evaluate the impact this intervention had on students' wellbeing and academic performance, a multi-institutional consortium of multidisciplinary partners purposively sampled 2,982 students and 580 teachers in 64 schools from five states in the Republic of South Sudan. Critical to the evaluation's aims was the design of a contextually relevant, rigorously validated instrument to measure students' wellbeing in a region where research on PSS outcomes in education in emergencies is needed. In this article, we first present the process by which these survey instruments were designed through the collaborative efforts of experts on measuring psychosocial support outcomes in conflict settings and experts on the local context. We then describe how we tested for the construct validity of the resulting instrument and present the results of our confirmatory factor analysis of its three-factor model of social wellbeing, emotional wellbeing, and resilience/coping. Finally, based on our process and the resulting instrument, we make recommendations for future research on PSS outcomes in emergency settings.

Theory of Geometric Shape Conversion
Authors: Mahmud Salman
Published: December 2021

In this paper we have proposed a new theory about geometric shape conversion. Through a particular process where the number of steps of the process tends to infinity, keeping one or more shapes of two or more shapes the same throughout the whole process and by gradually changing its size, shifting another shape toward another specific new size or new shape is the main topic of discussion of the theory. Again, if the shape that changes its size does not shift toward another specific new size or new shape then it is considered as error and this theory also discussed the properties of that error.
Examining Suicide and its Warning Signs and Determinants in a County of Illinois, 2014 to 2020: Implications for Future Research and Prevention
Authors: Siglock Aly , Xin Huaibo
Published: December 2021

This study is to examine the trend in suicide over the last 12 years in a county of IL; establish warning signs leading up to suicide; identify major risk factors of suicide among the decedents; as well as explore preventative measures for future suicide interventions. It’s a mixed-methods retrospective cross-sectional study. A total of 264 existing suicide case files between 2014 and 2020 were reviewed. Based on the current literature, the suicide data collection instrument was developed to include four sections: demographics, medical history, warning signs, and risks of suicide. A total of 96 variables were included to collect both quantitative and qualitative data. Data were analyzed both quantitatively and qualitatively. From 2014 to 2020, a total of 264 suicide deaths occurred in the county with the highest number in 2017 and lowest in 2010. Approximately 77.3% of the suicide deaths were males and 81.1% were non-veterans. About 31.4% of the cases left a suicide note; 22.1% had previously attempted suicide; and 49.2% had previous suicide ideation. About 39.4% of the deaths were caused by gunshot wounds, 39.4% were caused by suffocation, and 15.5% were caused by poisoning. More than half of the cases (58.3%) had a mental illness, including depression, anxiety, and bipolar disorder. Nearly 45.5% of the cases were taking prescription medications. Roughly 41.7% of the cases indicated they were in a troubled relationship, 33.0% indicated they could be grieving the loss of parents, significant others, children, and siblings. Only 23.9% of the cases had received suicide prevention treatment, such as hospitalization or admittance to a mental health center, prior to their suicide death. Future endeavors should consider developing suicide prevention strategies/interventions within the domains of the Social Ecological Model, including building social capital, issuing temporary firearms restraining orders, and establishing community-based suicide prevention training/screening programs.

Published: December 2021

We examined the intersection of alcohol use and hookups among transgender college students to identify sexual behaviors that may reduce negative hookup experiences. Our analytic sample included US college students who identified as transgender (n=36; 11 trans men and 25 trans women). Descriptive analyses were performed using the Online College Social Life Survey (2005–2011) to describe transgender students’ alcohol use, hookups, and related sexual behaviors. Twenty-five (69.4%) transgender students reported a hookup since entering college. The majority (n=19; 76.0%) of hookups included only non-penetrative sexual behaviors. Of these hookups, nearly half (n=9; 47.4%) reported heavy drinking. Some condom use was reported with penetrative hookups. This suggests that transgender students use some lower risk strategies during hookups. Alcohol use was high, which has implications for the consistent use of these behaviors to reduce negative hookup experiences.
Case Report: A Pseudoaneurysm Involving the Left Common Iliac Artery Secondary to Brucellosis: A Rare Case Report
Authors: Wang Qilong , Tang Liang , Qin Yue , Wang Qi , Zhang Ping , Cheng Zhihua
Published: December 2021

Pseudoaneurysms of the common iliac artery caused by Brucellosis are exceedingly uncommon. Infected common iliac artery pseudoaneurysms, particularly those caused by brucellosis, are more difficult to diagnose and cure than general pseudoaneurysms. The risk of mortality is significantly high in this condition. Nonsurgical treatment of a brucellosis-induced common iliac artery pseudoaneurysm is futile, and it should be operated on as soon as feasible. Long-term and multi-course antibacterial therapy with combination antibiotics is required. For the treatment of Brucella-infected pseudoaneurysms, endovascular surgery can be both effective and safe.

Heart failure development is characterized by persistent inflammation and progressive fibrosis owing to chronic catecholamine stress. In a chronic stress state, elevated catecholamines result in the overstimulation of beta-adrenergic receptors (βARs), specifically β2-AR coupling with Gαi protein. Gαi signaling increases the activation of receptor-stimulated p38 mitogen-activated-protein-kinases (p38 MAPKs) and extracellular signal-regulated kinases (ERKs). Phosphorylation by these kinases is a common way to positively regulate the catalytic activity of A Disintegrin and Metalloprotease 17 (ADAM17), a metalloprotease that has grown much attention in recent years and has emerged as a chief regulatory hub in inflammation, fibrosis, and immunity due to its vital proteolytic activity. ADAM17 cleaves and activates proinflammatory cytokines and fibrotic factors that enhance cardiac dysfunction via inflammation and fibrosis. However, there is limited information on the cardiovascular aspect of ADAM17, especially in heart failure. Hence, this concise review provides a comprehensive insight into the structure of ADAM17, how it is activated and regulated during chronic catecholamine stress in heart failure development. This review highlights the inflammatory and fibrotic roles of ADAM17’s substrates; Tumor Necrosis Factor α (TNFα), soluble interleukin-6 receptor (sIL-6R), and amphiregulin (AREG). Finally, how ADAM17-induced chronic inflammation and progressive fibrosis aggravate cardiac dysfunction is discussed.
A Prognostic Pyroptosis-Related lncRNAs Risk Model Correlates With the Immune Microenvironment in Colon Adenocarcinoma
Authors: Xia Fada , Yan Yuanliang , Shen Cong
Published: December 2021

Recent studies have indicated that long non-coding RNAs (lncRNAs) may participate in the regulation of tumor cell proptosis. However, the connection between lncRNA expression and pyroptosis remains unclear in colon adenocarcinoma (COAD). This study aims to explore and establish a prognostic signature of COAD based on the pyroptosis-related lncRNAs. We identify 15 prognostic pyroptosis-related lncRNAs (ZNF667-AS1, OIP5-AS1, AL118506.1, AF117829.1, POC1B-AS1, CCDC18-AS1, THUMPD3-AS1, FLNB-AS1, SNHG11, HCG18, AL021707.2, UGDH-AS1, LINC00641, FGD5-AS1 and AC245452.1) from the TCGA-COAD dataset and use them to construct the risk model. After then, this pyroptosis-related lncRNA signature is validated in patients from the GSE17536 dataset. The COAD patients are divided into low-risk and high-risk groups by setting the median risk score as the cut-off point and represented differences in the immune microenvironment. Hence, we construct the immune risk model based on the infiltration levels of ssGSEA immune cells. Interestingly, the risk model and immune risk model are both independent prognostic risk factors. Therefore, a nomogram combined risk score, immune risk score with clinical information which is meaningful in univariate and multivariate Cox regression analysis is established to predict the overall survival (OS) of COAD patients. In general, the signature consisted of 15 pyroptosis-related lncRNAs and was proved to be associated with the immune landscape of COAD patients.
