Features of compaction of sedimentary rocks of oil and gas deposits
Authors: Mamyashev V. G. , Kuznetsova A. M. 
Published: March 2023

The process of compaction of sediments determines the patterns of changes in the properties of rocks of oil and gas bearing sections, primarily their porosity. The porosity of rocks of different lithology varies depending on their depth. The study of the regularities of changes in the porosity of rocks is important for the identification of geological sections, for substantiating the intervals of the existence of reservoirs with intergranular porosity type, for forecasting the properties of support layers by section and for methodological support for the geological interpretation of the materials of geophysical studies of wells. The existing concept of gravitational compaction of sediments doesn't reflect a number of features of this process of rocks in real conditions. The article substantiates the conditions of precipitation formation corresponding to their transition to an initial relatively stable state. The features of precipitation formation in the initial marine and continental conditions, as well as the features of their formation in permafrost strata are substantiated.The general patterns and features of the compaction curves of typical sandstones and clays are considered according to the data of reference wells drilled within the West Siberian oil and gas basin.

Published: March 2023

Global climate change and its impact on the environment is one of the main problems of the 21st century. In the Arctic zone, where considerable oil and gas reserves are located, warming is 2-3 times faster than the world average. Against the backdrop of increased Arctic warming, thermal pollution has created permanent urban heat islands, where urban temperatures are 1-2 degrees Celsius higher than in surrounding areas. The aim of the article was a geoinformation assessment of climatic and anthropogenic characteristics in various zones of Tyumen (recreational zones (parks and reservoirs) and the zone of urban highways) in the summer of 2021. The Earth program was used in the studies, statistical processing of the results was carried out using the IBM SPSS Statistics 21 software. It has been found that a circadian diurnal rhythm is observed both in recreational areas (parks and reservoirs) and in the area of urban highways (wind speed, temperature and relative humidity, concentration of CO, CO2, SO2, NO2) in the summer of 2021. The revealed correlation relationships between climatic characteristics and anthropogenic pollutants and aerosols indicate that global climate change is associated with the deterioration of the ecological situation in the urban environment and doesn't depend on the landscape features of the city.

Expanding Refugee Ineligibility: Canada’s Response to Secondary Refugee Movements
Authors: Atak Idil , Alrob Zainab Abu , Ellis Claire 
Published: March 2023

<p> In 2019, Canada introduced legislative changes that made asylum seekers ineligible for protection if they have made a previous refugee claim in a country that Canada shares an information-sharing agreement with. Such agreements are currently in place with the US, Australia, the UK, and New Zealand. This article offers a critical assessment of the newineligibility ground, arguing that the policyis designed to deter secondary refugee movements, particularly those across the Canada–US border which have considerably intensified since 2017. Based on the ‘first safe country’ rule, the new ineligibility ground enables Canada to exclude some asylum seekers from refugee protection without offering any alternative effective protection in Canada. This article demonstrates that the policy is inconsistent with Canada’s obligations under international refugee law. </p>
Not Only A Man’s World: Women Also Cross Borders
Authors: Liman Maryam 
Published: March 2023

The migrants from Niger Republic move into the neighboring Nigerian communities in numbers in search for greener pastures. Previously, research in the region has shown migration to be male dominated (Liman, 2021). However, a new wave of women participation was noticed hence the need for literature update. The study was conducted at Daura Local Government Area, Katsina state in Nigeria. The study area shares with Niger Republic a manned border at Kongolom and unmanned borders throughout the expanse of its several remote villages making the influx of both human and animal resources uncontrolled. Women, just like men move freely into the study area yearly. In order to understand the reasons behind the decision by these women to cross the borders, four (4) Focus Group Discussions were conducted with the 35 migrants using a checklist as a guide. Four (4) Key Informant Interviews (KIIs) also held with their hostesses. Qualitative data was therefore collected and reported in descriptive narration. The results of the FGD show all respondents were female within the age range of 12-56years. Some were married, some widowed, a good number divorced and the rest were spinsters. None of them had formal education but some had basic Islamic knowledge. They engaged in farming, post harvest activities, domestic chores such as cleaning, cooking and babysitting and others street begging. Findings reveal that economic gains were the major reason for coming to Nigeria. For some respondents, this is the first time of partaking in migration, others have had the joy of returning yearly thereby making them circular migrants. These ladies and others practicing this migration type are commonly referred to as ‘Yan Tabiradi. Information gathered from the 3 of 4 of the hostesses, who were elderly women, all widowed and lived in 2-3 room houses explained that some migrants pay a token fee to stay (N150-N200 monthly/less than 50cents) for accomodation. The fourth hostess, relatively younger, entertained her relatives at no cost. Finally, it can be concluded that, women from southern Niger Republic do partake actively in short distance, seasonal, circular migration in parts of northern Nigeria. They come due to availability of work, a good network of family and friends that secure the work and accommodate them and also the ease of crossing the border.

ABSTRACT
This paper articulates the new high school, its developments with the interests of the business community, and the challenges of teaching history. Our question is, what are the implications of new high school in teaching history? This discussion is extremely relevant due to the implementation process of this new high education in the different states of Brazil. The general objective is to discuss the implications of the presence of the business community in the new high school and its relationship with the teaching of history. As specific objectives, we have: (I) to reflect on the main changes in the new high school; (II) Asses the interests of the business community in the new high school; (III) Present the main impacts of the new high school on the teaching of History. We used qualitative methods, bibliographical, and exploratory research. The study evidenced the great interest of the business community articulated with the need for change in secondary education for the project of hegemonization of the working class towards capitalism and the emptying of history teaching. Significant increase in workload, expansion of training itinerary, and disarticulation of access to historically accumulated knowledge. Unfortunately, neoliberal interests cross the economy and devastate education, making it impossible to continue the historical achievements. Finally, there is an invitation to the resistance of history teachers.

Poly (vinyl chloride) (PVC) is commonly used to manufacture biomedical devices and hospital components, but it does not present antimicrobial activity enough to prevent biofouling. With the emergence of new microorganisms and viruses, such as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that was responsible for the global pandemic caused by Coronavirus Disease 2019 (COVID-19), it is evident the importance of the development of self-disinfectant PVC for hospital environments and medical clinics where infected people remain for a long time. In this contribution, PVC nanocomposites with silver nanoparticles (AgNPs) were prepared in the molten state. AgNPs are well-known as antimicrobial agents suitable for designing antimicrobial polymer nanocomposites. Adding 0.1 to 0.5 wt% AgNPs significantly reduced Young’s modulus and ultimate tensile strength of PVC due to the emergence of microstructural defects in the PVC/AgNP nanocomposites, but the impact strength did not change significantly. Furthermore, nanocomposites have a higher yellowness index (YI) and lower optical bandgap values than PVC. The PVC/AgNP nanocomposites present virucidal activity against SARS-CoV-2 (B.1.1.28 strain) within 48 h when the AgNP content is at least 0.3 wt%, suitable for manufacturing furniture and hospital equipment with self-disinfectant capacity to avoid secondary routes of COVID-19 contagion.

BackgroundAtrial fibrillation (AF) is a prevalent arrhythmia, that causes thrombus formation, ordinarily in the left atrial appendage (LAA). The conventional metric of stroke risk stratification, CHA2DS2-VASc score, does not account for LAA morphology or hemodynamics. We showed in our previous study that residence time distribution (RTD) of blood-borne particles in the LAA and its associated calculated variables (i.e., mean residence time, tm, and asymptotic concentration, C∞) have the potential to improve CHA2DS2-VASc score. The purpose of this research was to investigate the effects of the following potential confounding factors on LAA tm and C∞: (1) pulmonary vein flow waveform pulsatility, (2) non-Newtonian blood rheology and hematocrit level, and (3) length of the simulation.MethodsSubject-Specific data including left atrial (LA) and LAA cardiac computed tomography, cardiac output (CO), heart rate, and hematocrit level were gathered from 25 AF subjects. We calculated LAA tm and C∞ based on series of computational fluid dynamics (CFD) analyses.ResultsBoth LAA tm and C∞ are significantly affected by the CO, but not by temporal pattern of the inlet flow. Both LAA tm and C∞ increase with increasing hematocrit level and both calculated indices are higher for non-Newtonian blood rheology for a given hematocrit level. Further, at least 20,000 s of CFD simulation is needed to calculate LAA tm and C∞ values reliably.ConclusionsSubject-specific LA and LAA geometries, CO, and hematocrit level are essential to quantify the subject-specific proclivity of blood cell tarrying inside LAA in terms of the RTD function.

Published: March 2023

IntroductionThe personalized management of differentiated thyroid cancer (DTC) is currently based on the postoperative TNM staging system and the ATA risk stratification system (RSS), both updated in 2018 and 2015, respectively.PurposeWe aimed to evaluate the impact of the last two editions of TNM and ATA RSS in the prediction of persistent/recurrent disease in a large series of DTC patients.Patients and methodsOur prospective study included 451 patients undergone thyroidectomy for DTC. We classified the patients according to TNM (both VIII and VII ed.) and stratified them according to the ATA RSS (both 2015 and 2009). We then evaluated the response to the initial therapy after 12-18 months according to the ATA “ongoing” risk stratification, and analyzed the variables associated with persistent/recurrent disease by multivariate analysis.ResultsThe performance of the last two ATA RSSs was not significantly different. By staging patients according to the VIII or VII TNM editions, we found significant differences only in the distribution of patients with structural disease classified in stages III and IV. At multivariate analysis, only T-status and N-status were independently associated with persistent/recurrent disease. Overall, ATA RSSs and TNMs showed low predictive power in terms of persistent/recurrent disease (by Harrell’s test).ConclusionsIn our series of DTC patients, the new ATA RSS as well as the VIII TNM staging provided no additional benefit compared to the previous editions. Moreover, the VIII TNM staging system may underestimate disease severity in patients with large and numerous lymph node metastases at diagnosis.

Background and objectiveSickle cell disease (SCD) is a very common autosomal recessive hemoglobinopathy leading to multiple pulmonary complications that are closely associated with mortality. The pathophysiology of chronic pulmonary involvement is not yet fully understood and no specific therapies are available.MethodsThe aim of this cross-sectional study was to characterize the lung function of children and young adolescents with SCD in a German single-center cohort and to extend conventional lung function testing by the use of a new imaging method. We performed spirometry and body plethysmography in 35 children and young adults with hemoglobin SS, SC, S/β-thalassemia as well as 50 controls. These data were compared with clinical characteristics and typical laboratory parameters of hemolysis and disease activity in SCD. To identify lung inhomogeneities, for example due to atelectasis, hyperinflation, air trapping or vascular occlusions, we used the promising new method of electrical impedance tomography (EIT) and calculated global inhomogeneity indices.ResultsLung function of patients with SCD was significantly reduced compared to that of healthy controls. When the result was found to be pathological, the most commonly observed type of breathing disorder was classified as restrictive. Laboratory parameters showed typical features of SCD including decreased levels of hemoglobin and hematocrit and elevated levels of leucocytes, platelets, lactate dehydrogenase and total bilirubin. However, there was no correlation between blood values and reduced lung function. Electrical impedance tomography (EIT) revealed no abnormalities in SCD patients compared to healthy controls. In particular, we were unable to demonstrate any regional inhomogeneities in lung ventilation.ConclusionIn our study, SCD patients showed impaired lung function, with a relevant percentage of patients suffering from restrictive breathing disorder. Signs of obstruction could not be detected. Electrical impedance tomography (EIT) measurements revealed no unevenness that would suggest air entrapment, blockage of blood vessels, excessive inflation, obstruction, or other forms of lung disease. Additionally, the reduction in lung function observed in SCD patients was not related to the disease severity or laboratory test results.

Published: March 2023

IntroductionWorldwide, there is a high frequency of chronic non-specific low back pain (CNLBP), which is a significant public health concern. The etiology is complicated and diverse, and it includes a number of risk factors such as diminished stability and weak core muscles. Mawangdui-Guidance Qigong has been employed extensively to bolster the body in China for countless years. However, the effectiveness of treating CNLBP has not been assessed by a randomized controlled trial (RCT). In order to verify the results of the Mawangdui-Guidance Qigong Exercise and examine its biomechanical mechanism, we intend to perform a randomized controlled trial.Methods and analysisOver the course of 4 weeks, 84 individuals with CNLBP will be randomly assigned to receive either Mawangdui-Guidance Qigong Exercise, motor control exercise, or medication (celecoxib). Electromyographic data, including muscle activation time, iEMGs, root mean square value (RMS) and median frequency (MF), will be the main outcomes. The Japanese Orthopedic Association (JOA) Score, the Mcgill Pain Questionnaire (MPQ), beta-endorphin, and substance P are examples of secondary outcomes. At the start of treatment and 4 weeks later, all outcomes will be evaluated. SPSS version 20.0 (SPSS Inc., Chicago, IL, USA) will be used for all of the analysis.DiscussionThe prospective findings are anticipated to offer an alternative treatment for CNLBP and provide a possible explanation of the mechanism of Mawangdui-Guidance Qigong Exercise on CNLBP.Ethics and disseminationThe Sichuan Regional Ethics Review Committee on Traditional Chinese Medicine has given the study approval (Approval No. 2020KL-067). It has also registered at the website of China Clinical Trial Center Registration. The application adheres to the Declaration of Helsinki’s tenets (Version Edinburgh 2000). Peer-reviewed papers will be used to publicize the trial’s findings.Trial registration numberClinicalTrials.gov, identifier ChiCTR2000041080.
