Authors: Ma Mengyuan , Jiang Mingshun , Zhang Lei , Sui Qingmei , Jia Lei
Published: July 2024

This paper presents a signal correlation–based two-sided detection method to detect delamination defects in widely used carbon fiber reinforced plastics with high accuracy and a convenient process. This method can improve the accuracy of ultrasonic testing and distinguish non-defective signals from defective signals, especially those with small amplitude, and to present the depth and size of defects by images. We combined the echo signals from both sides of ultrasonic detection at the same location to extract the weak defect signals and achieved the detection of materials with high ultrasonic attenuation. First, empirical mode decomposition filtering is performed on the ultrasonic raw signal. Then, the defect echoes are identified by smart thresholding and combined with the results of ultrasonic detection on both sides. Next, the defect depth and size are calculated, and the defect image is drawn. Finally, the ultrasonic phased array C-scan obtained by the ultrasonic phased array equipment was compared with the detection results of carbon fiber laminates with artificial delamination by the algorithm of the present invention, showing that the proposed algorithm defect depth calculation error is less than 4 %, the defect size calculation error is less than 0.5 mm, and it performs well in defect shape presentation and position calculation.
Microstructure Analysis, Piezoelectrical Resistivity, and Compressive Strength Concrete Incorporated with Waste Steel Slag as a Fine Aggregate Replacement
Authors: Piro Nzar Shakr , Mohammed Ahmed Salih , Hamad Samir M.
Published: July 2024

This study aims to investigate the effect of waste steel slag (SS) as partially replaced with cement and fine aggregate on conventional concrete for different mixes named M25, M35, and M47 in terms of compressive strength (CS), electrical resistivity (ER), and piezoresistivity behavior. SS is a molten mixture of silicates and oxides that solidifies upon cooling, a byproduct of the steel-making process. Before doing the design experiments, the optimum value of SS as powder and fine aggregate was determined using seven different mixes to investigate the effect of different SS sizes on the CS and piezoresistivity of normal concrete. Based on the results achieved, the optimum value and size of SS were selected to modify and investigate the effect of SS on three different mixes of conventional concrete named M25, M35, and M47 in terms of CS, ER, and piezoresistivity behavior. The resistivity of all concrete mixes was measured using four-probe from early curing to 28 days of curing time. The results demonstrated that M47 mix modified with SS has lower resistivity than the rest of the concrete mixes. The results of piezoresistivity behavior indicated that M47 mix modified with SS has a higher resistivity change while applying stress at 3 days of curing compared to the M25 and M35 concrete mix modified with SS by 44.1 % and 37.6 %, respectively. The Vipulandanan p-q model was applied to predict both ER versus time and change of resistivity versus stress for all mixes. The results demonstrated that the model predicted the change of resistivity versus applied stress with a high coefficient of determination that varied between 0.82 and 0.989, and a low root mean square error changed between 0.81 Ω.m and 7.94 Ω.m.
Mechanical Properties of Cotton and High-Performance Fiber Blended Denim Fabrics for Motorcycle Protective Clothing
Authors: Natarajan Gayathri , Palani Rajan T.
Published: July 2024

This research paper article thoroughly investigates the tensile, tear, and abrasion properties of high-performance cotton denim fabrics incorporating para-aramid and ultrahigh molecular weight polyethylene (UHMWPE) fibers. It compares these high-performance blended denim fabrics with traditional 100 % cotton fabric material. The findings indicate that fabrics containing UHMWPE and para-aramid fibers demonstrate notably greater strength and durability compared with pure cotton fabrics. Factors such as yarn thickness, twist, fabric weight, cover factor, and the blend proportion of high-performance fibers contribute to enhanced tensile strength and abrasion resistance. Among the tested samples, the blend with 30 % cotton and 70 % UHMWPE fibers, weighing 430 g/m2 (S9), exhibits the most superior performance in terms of tensile strength. These fabrics also exhibit remarkable tear resistance, even under extreme conditions. Sample S9 excels in abrasion resistance, qualifying it for Zone 3 Level 1 protection. The study underscores the potential of these fabrics to offer outstanding protection against abrasion in diverse applications. Additionally, it has been observed that fabrics generally display higher tensile strength and abrasion resistance along the warp direction, owing to a higher yarn density. The analysis of variance and Tukey Honestly Significant Difference (HSD) tests confirm the significant influence of fiber composition on fabric properties based on the statistical analyses that have been conducted.
Experimental Investigation of Crack Tip Constraint Effects on Fracture Assessment of API 5L X65 Steel Grade for Low-Temperature Applications (−120°C)
Authors: Sukpe Paul , Vignjevic Rade , Hughes Kevin , Kulka Rob
Published: July 2024

Crack tip constraint is a significant issue in engineering components’ design and repair decisions. The main reason is that fracture assessment procedures, such as BS 7910, rely on lower-bound fracture toughness test data from deeply cracked bend specimens. This can generate stress states under various loading conditions with an appropriate crack tip stress triaxiality for metallic structures. Many real components (e.g., oil and gas pipelines) have small in-plane (shallow cracks) and out-of-plane (thin-wall thickness) dimensions that can cause a reduction in crack tip constraint to a considerable amount, thereby increasing the fracture toughness. As such, the structural assessment of low-constraint structural components using fracture toughness data obtained from deeply notched specimens may be safe but overly conservative, resulting in unnecessary repair shutdowns and costs. Consequently, relating fracture toughness values determined from laboratory specimens to real structural components becomes an issue in structural integrity assessments based on the two-parameter fracture mechanics methodology. This study investigates the applicability of the constraint-based failure assessment diagram (FAD) approach for the evaluation of cracked pin-loaded single-edge notched tension and three-point single-edge notched bend specimens at low (−120°C) and room temperatures. The analyses reveal that the experimentally measured toughness values, J0, depend on the crack sizes for the considered specimen geometries (a/W = 0.1, 0.3, 0.5). The results show the benefits of using constraint-modified FAD approach for the assessment of shallow cracks. Therefore, the enhanced toughness associated with constraint reduction indicated an increased margin and allows realistic design and repair decision-making that can help prevent catastrophic failures.

Reducing Erythrocyte Sedimentation Rate Ordering: De-implementation and Diagnostic Stewardship
Authors: Fatemi Yasaman , Polsky Tracey , Burns Julianne , L’Etoile Nathan , Obstfeld Amrom , Zorc Joseph J. , Nord Ellen , Coffin Susan , Shaw Kathy
Published: July 2024

OBJECTIVES

The Choosing Wisely campaign recommends against the routine use of erythrocyte sedimentation rate (ESR) for the assessment of acute undiagnosed inflammation or infection. We examined ESR and C-reactive protein (CRP) ordering practices at a large, freestanding children’s hospital. We found that 80% of ESR orders were placed concurrently with a CRP order. We aimed to reduce the ESR testing rate by 20% within 6 months in both inpatient and emergency department (ED) settings.

METHODS

Applying Lean process improvement principles, we interviewed stakeholders from multiple subspecialties and engaged the institutional laboratory stewardship committee to identify the root causes of ESR ordering and design interventions. We conducted provider education (November 2020) and employed clinical decision support through an order panel in the electronic health record (April 2021). The outcome measures were monthly ESR testing rate per 1000 patient days (inpatient) and per 1000 ED visits, analyzed using statistical process control charts. CRP testing rate was a balancing measure.

RESULTS

After intervention implementation, the ESR testing rate decreased from 11.4 to 8.9 tests per 1000 inpatient patient days (22% decrease) and from 49.4 to 29.5 tests per 1000 ED visits (40% decrease). This change has been sustained for >1 year postintervention. Interventions were effective even during the coronavirus disease 2019 pandemic when there was a rise in baseline ED ESR ordering rate. CRP testing rates did not increase after the interventions.

CONCLUSIONS

Education and clinical decision support were effective in reducing the ESR ordering rate in both inpatient and ED settings.

Parameters and Modes of a Hydraulic Mini Seeder Operation for Small-Seeded Vegetable Crops
Authors: Truflyak Evgeny V. , Skorobogachenko Ivan S. , Konovalov Vladimir I.
Published: July 2024

Introduction. In the area of sowing with water and suspensions, there has been observed the trend of the development of hydroseeding lawn grass. The direction is less studied for sowing small seeds (germinated and sprouted) of vegetables. Existing works are mainly aimed at substinating the sowing of germinated seeds of watermelons, pumpkins, cucumbers and tobacco. At the same time, there are no studies for hydroseeding of carrot, parsley, dill, lettuce, tomatoes and celery seeds. Thus, theoretical research aimed at substantiating the method and technical solutions for sowing small-seeded crops in open and closed ground conditions are relevant. The problem is the lack of constructive-technological scheme of the tank for formation of sowing mixture of small-seeded crops, design and mode parameters of hydraulic mini seeder for sowing in drills to increase the efficiency of sowing.
Aim of the Study. The study is aimed at optimizing parameters and modes for operation of a hydraulic mini seeder for sowing in drills.
Materials and Methods. Theoretical studies of the process of homogenization of the seed mixture, power consumption during the operation of the reservoir for the formation of the seed mixture were carried out. Laboratory studies were carried out in Kuban State Agrarian University, field studies in private farms of Krymsky district of Krasnodar Krai.
Results. There have been jbtained the expressions describing the dependence of the value of the average circumferential velocity of the seed mixture flow and the power during the operation of the reservoir for the formation of seed mixture for various combinations of design and operating parameters. The analytical dependence describing the value of seed concentration in the carrier medium at a specified moment of time at a fixed point of the tank height is presented.
Discussion and Conclusion. Optimal parameters and modes for the operation of a universal hydroseeder for a seeding step are: agitator rotation frequency ‒ 92 min–1; crane opening value – 47%; seeder speed – 3.1 m/s at seeding step 20.5 mm; for seeding step variation coefficient: agitator rotation frequency ‒ 87 min–1; crane opening value – 56%; seeder speed – 2.7 m/s at seeding step variation 15%. The use of suspensions for hydroseeding vegetable crops is promising and should be developed.
Compilation and uses of the ‘Yonsei Korean Synonyms Dictionary for Learners’
Authors: Bong Mikyung , Kim Sunhye
Published: July 2024

The purpose of this study is to introduce the compilation process and characteristics of the new Yonsei Korean Synonyms Dictionary (YKSD), and to suggest how the synonym dictionary could be used in teaching language. Despite the importance of synonym distinction for language learners and teachers, thus far, synonym dictionaries have generally presented lists of synonyms, in a manner similar to a thesaurus. We would like to introduce the YKSD as a new model for a Korean thesaurus, and discuss what information is presented and how the information is illustrated. We provide the lexical information and description of synonyms based on an analysis of corpus rather than the intuition of dictionary compilers. The macrostructure and microstructure of the YKSD are specially designed to assist in distinguishing synonyms. The contents of this dictionary can be used in various ways in the course of developing teaching materials for language learners. In this study, we will look at the uses of this dictionary.

This piece is a bibliographic oddity. It constitutes a paper given by Stephen Mennell at the Oxford Symposium in 1984. It was not included in the published proceedings because it was erroneously thought to have been put into print elsewhere. When looking it out for purposes of citation, Mennell was aghast to find it had never in fact been published and, thinking the arguments retained much of their force, proposed it for PPC. Readers should note that it antedates the author’s All Manners of Food (currently, the second edition, Illinois, 1996).

Introduction: To prevent vaginal stenosis, the use of a vaginal dilator is recommended. Objective: To analyze sociodemographic data, gynecological conditions and the use of vaginal dilator after pelvic brachytherapy. Materials and Methods: Cross-sectional, retrospective study, period 2016-2020, collected between October/2020 and February /2021, from records of women with gynecological cancer treated with brachytherapy at the Centro de Pesquisa Oncológicas (Brazil). The variables included sociodemographic data and gynecological conditions in following the treatment. In the analysis, descriptive statistics, chi-squaretest, Fisher's exact test and Mann-Whitney test were applied. Results: 519 patients records were included in the investigation; the analyzes showed significant associations between the topography and staging (p<0.001), education (p=0.004) and age (p<0.001); the comparison between the distribution of the ionizing radiation dose showed a difference with the continued sexual relationship category (p=0.006); the comparison between the proportions of continued sexual relationship and using a vaginal dilator was significant (p<0.001); 49.10% (131) adhered to the use of vaginal dilator; 24.50% (127) are not sexually active and do not adhere to the use of the dilator. Discussion: It is evident that social and gynecological conditions interfere with the presence of vaginal stenosis and the use of a vaginal dilator after pelvic brachytherapy. Conclusions: The adherence found in the use of dilator affirms the contributions and the need for health education by nurses and physicaltherapists during and following the treatment.

Aim. To study the risk of type 2 diabetes (T2D) using the Finnish Diabetes Risk Score (FINDRISC) and its contribution to all-cause mortality and cardiovascular events in the Russian population aged ­25-64 years.

Material and methods. Data from cross-sectional studies ESSE-RF and ESSE-RF2 are included. The random sample was formed using the Kish method. Response was ~80%. The modular questionnaire in­cluded socio-demographic variables, medical history, and main risk factors for noncommunicable diseases. Blood was collected from the antecubital vein on an empty stomach. Biochemical parameters were determined in the clinical diagnostic laboratory of the National Medical Research Center for Therapy and Preventive Medicine. The presence of T2D was determined by questionnaire and/or fasting plasma glucose level ≥7,0 mmol/L. Obesity was defined as a body mass index of ≥30,0 kg/m2; abdominal obesity was defined as a waist circumference of ≥102 cm in men and ≥88 cm in women. FINDRISC risk was graduated as follow: low (<7), slight (7-11), moderate (12-14), high (15-20), very high (>20). Persons with diabetes and pregnant women were excluded. The final sample included 26418 people (10268 men and 16150 women). From 14 regions, ESSE-RF and ESSE-RF2 formed a prospective follow-up cohort (n=22812), median follow-up — 7,5 years). Statistical processing was performed using the open-source statistical programming language and environ­ment R (version 4.1).

Results. A fifth of people aged 25-64 years are at ≥ moderate risk of T2D. The rate of FINDRISC ≥15 was 10,1% (women 12,4% vs men 6,4%, p<0,001); ≥12 points — 23,7%. A close relationship was found between impaired fasting glucose and the risk of T2D with FINDRISC ≥15 and ≥12 (p<0,001). Survival worsens for FINDRISC ≥12 and ≥15, with the worst survival rates in individuals with T2D (p<0,001). The likelihood of cardiovascular events consistently increases with FINDRISC ≥12, ≥15, and T2D. In the Cox model, only T2D is significant for all-cause mortality; FINDRISC ≥15 and T2D are significant for the cardiovascular and combined endpoints.

Conclusion. An important task of the medical community is to identify individuals at risk of T2D at the population level. Early prevention of T2D risk factors can delay or prevent both T2D and cardiovascular events.

Published: July 2024

Aim. To evaluate the relationship between markers of inflammation and matrix remodeling and criteria for a vulnerable plaque according to multislice computed tomography (MSCT) coronary angiography, as well as lipid profile parameters in patients with acute coronary syndrome (ACS).

Material and methods. This prospective single-center study included 125 patients admitted urgently with ACS. All patients underwent percutaneous coronary intervention of the infarct-related artery. In ad­dition, in all patients, there were plaques in one or two non-infarct-related arteries with stenosis <50%. ACS was treated according to clinical guidelines, including statin therapy at the maximum dosage. After 1 month, all patients underwent MSCT coronary angiography to detect vulnerable plaques, as well as assessment of the lipid profile, and following biomarkers of inflammation and matrix remodeling: metalloproteinase-9 with its inhibitor type 1 (MMP-9 and TIMP-1), galectin-3 (Gal-3), neutrophil gelatinase-associated lipocalin (NGAL).

Results. Of the 125 patients, myocardial infarction (MI) was diagnosed in 94 people (75%). Criteria for the plaque vulnerability according to MSCT were identified in 55 (44%) patients, of which positive remodeling was detected in 35 patients, a low-density area (LDA) in 30, and punctate calcifications (PCs) in 11. Gal-3 concentration was significantly higher without LDA — 35,4 (8,6; 65,0) ng/ml, in comparison with the group of patients in whom this criterion was detected and was 16,1 (5,9; 27,4) ng/ml (p=0,006). In the absence of PCs, the Gal-3 concentration was >34,0 (8,6; 61,0) vs 5,9 (2,8; 25,4) ng/ml in the group with PCs (p=0,046). The regression model including the MMP-9, TIMP-1, NGAL, Gal-3 in identifying vulnerable plaques was found to be significant (p<0,001).

Conclusion. Criteria for vulnerable plaque in patients after ACS have a significant relationship with markers of inflammation and matrix remo­deling.
Relationship between microplastics and cardiovascular risk factors
Authors: Mamedov M. N. , Savchuk E. A.
Published: July 2024

In recent years, plastic has been widely used in various anthropic activity fields, but its waste pollutes the environment. Under the influence of chemical processes, it decomposes micro- and nanoplas­tics, which enter the human body in various ways. New experimental studies indicate that they can cause a number of cardiovascular disorders, including endothelial cell dysfunction and induction of oxi­dative processes.

The article examines the impact of environmental pollution with microplastics on the development of cardiovascular diseases. It is clear that new data on this new risk factor are accumulating and further clinical studies are required.

COVARIANCE ESTIMATION USING h-STATISTICS IN MONTE CARLO AND MULTILEVEL MONTE CARLO METHODS
Authors: Shivanand Sharana Kumar
Published: July 2024

We present novel Monte Carlo (MC) and multilevel Monte Carlo (MLMC) methods to determine the unbiased covariance of random variables using h-statistics. The advantage of this procedure lies in the unbiased construction of the
estimator's mean square error in a closed form. This is in contrast to conventional MC and MLMC covariance estimators, which are based on biased mean square errors defined solely by upper bounds, particularly within the MLMC.
The numerical results of the algorithms are demonstrated by estimating the covariance of the stochastic response of a
simple 1D stochastic elliptic PDE such as Poisson's model.

Methods of design of experiment have been implemented for the evaluation of the impact of the inclusion of recycled coarse aggregates (RCA) and rice husk ash (RHA) on strength and other chosen parameters of concrete. A specific general factorial design method, two-way analysis of variance (Anova), has been used for the current exploration considering two key factors – that is, percentage of RCA (0% and 100%) and percentage of RHA (0%, 5%, 10%, 15%, 20%, 25%, 30% and 35%). This approach has been used to assess the effect of these materials on various concrete properties, including 3, 7, 28 and 90 days compressive strength, modulus of elasticity, water absorption, volume of voids and density. The outcomes of the analysis have been presented in the form of Anova table, individual, main effect, contour and interaction plots. The results of the analysis show that the levels of RCA and RHA had a significant effect on the properties of concrete.

South Sumatra region has abundant potential coal reserves, but the lack of structural and stratigraphic data makes it not be easy to map their total extent and to understand the genesis. These limitations can be partially resolved using the borehole well-logging methods. The aim of this research was to investigate correlation of coal seam lithology using the well-logging methods in a coalfield, location X, Musi Banyuasin, South Sumatra. The several exploration activities were conducted using the well-logging method to acquire gamma-ray logs and density logs data from seven boreholes, namely PMCBS12, PMCBS13, PMCBS14, PMCBS15, PMCBS16, PMCBS17, and PMCBS19 sites. WellCAD software was used during the data processing to derive logging data (gamma-ray and density logs), and Minex software was utilized to analyze the physical parameter correlation among boreholes. Borehole data analysis was carried out by analyzing the lithology contained in the borehole, especially to analyze the characteristics of the coal seam, such as depth and thickness. The results suggest that the thickness of the existing coal seam in area X is at seam 6 from a depth of about 2.95-19.95 m, with a coal seam thickness ranging from 1.85 m in the PMCBS12 to a thickness of 3.6 m in the PMCBS19 well. Two to three - vertically spread seams were found in each borehole with a thickness of about 0.35-3.6 m at various depths. Correlation results among boreholes show that the distribution of coal seams extends from the northwest to the southeast with a distribution direction of N300˚E/6˚.

Kína az elmúlt évtizedekben a technológiai fejlesztések előtérbe helyezésével és az abszorpciós stratégia a lkalmazásával jelentős fejlődést ért el az USA technológiai színvonalához történő felzárkózásban, azonban eddig nem sikerült sem elérnie, sem meghaladnia az USA képességeit. Jelenlegi stratégiai célja, hogy USA tól átvegye a technológiai vezető szerepet. A Kína által alkalmazott abszorpciós stratégia a jelenlegi technológiai környezetben nem alkalmas a technológiai vezetés átvételére, valamint rendszerszintű jellemzők is akadályozzák az innovációs képesség javulását. Kínának strat é giai célja elérése érdekéb en nagyobb hangsúlyt kell helyeznie a generatív innovációs képessége javításására és ez eredeti innovációkra.

Российская Федерация – правовое демократическое государство
Authors: Goshulyak V. V.
Published: July 2024

В статье рассматриваются конституционные характеристики Российского государства после конституционной реформы 2020 года. Автор выдвигает аргументы в обоснование позиции о том, что Российская Федерация продолжает оставаться правовым демократическим государством и после внесения поправок в Конституцию РФ.  Сделан вывод о том, что поправки не изменили и не размыли основы конституционного строя. Российская Федерация может считаться эталоном для называющих себя демократическими стран объединенного Запада, отказавшихся от верховенства права, многополярного мира, свободного и демократического развития других стран, не входящих в его состав, сделавших ставку на диктат и силовое решение назревших проблем мирового развития, не считающихся с общепризнанными принципами и нормами международного права.
К вопросу о темпорально-лимитированных законах в сфере трудовой деятельности при особых правовых режимах
Authors: Golyshev V. G. , Tsygankov A. Y.
Published: July 2024

Изменения в российской экономике, все чаще возникающие периоды глобальной и внутренней экономической нестабильности, проблемы экономического развития и роста, нехватка средств для финансирования различных отраслей производства требуют повышения роли изменения трудового законодательства в период проведения Специальной военной операции. Происходящие изменения в экономической жизни страны не могли не сказаться на правовой регламентации труда как эффективного регулятора процесса распределения и перераспределения трудовых ресурсов. Трудовой кодекс Российской Федерации среди основных целей трудового законодательства называет защиту прав и интересов работников и работодателей. Исследуется вопрос темпорально-лимитированного законодательства, регулирующего трудовую деятельность граждан в обстоятельствах возникновения особых правовых режимов, основной акцент из которых, в свою очередь, делается на военное положение. Исследуемая проблема является актуальной в связи с тем, что в наше время государства продолжают сталкиваться с угрозами, требующими введения военного или чрезвычайного положения, которые в последующем определяют особый порядок функционирования производственных предприятий и организаций.
О праве адвоката – представителя потерпевшего на обоснование меры наказания
Authors: Taran A.S. , Zhirova M.Iu. , Iunoshev S.V.
Published: July 2024

Рассматривается вопрос оправе адвоката – представителя потерпевшего обосновывать перед судом предлагаемую меру наказания для подсудимого. Показано, что в научной литературе утверждение о недопустимости для адвоката – представителя потерпевшего вступать в обсуждение вопроса о мере наказания, подлежащего назначению подсудимому, является достаточно традиционным. Такой подход обосновывается прежде всего ссылками на профессиональную этику адвокатов. В связи с этим анализируются исторические, правовые и нравственные истоки данного подхода. Констатируется, что в современных процессуальных реалиях право адвоката – представителя потерпевшего на обоснование предлагаемой меры наказания является неотъемлемой частью реализации им функции обвинения и, как следствие, полномочий обвинителя. В обоснование этой позиции подвергаются анализу соответствующие правовые позиции Конституционного Суда РФ, нормы Уголовно-процессуального кодекса РФ, Федерального закона «Об адвокатской деятельности и адвокатуре в Российской Федерации», Кодекса профессиональной этики адвоката.

Mantle Wedge Heterogeneities and Afterslip Distribution Following the 2004 Mw 9.2 and 2005 Mw 8.6 Sumatra Earthquakes
Authors: Yang Siyuan , Hu Yan , Zhang Jian
Published: July 2024

Viscoelastic postseismic deformation following the 2004 Mw 9.2 Sumatra and 2005 Mw 8.6 Nias earthquakes extend thousands and hundreds of kilometers from the rupture area, respectively, providing an opportunity to better understand the rheology of the northern Sumatra subduction zone. We have developed a 3D viscoelastic finite-element model to study the postseismic deformation of the 2004 and 2005 events. The time-dependent and stress-driven afterslip is simulated by a 2-km-thick shear zone. Model results indicate that the viscosity of the shear zone of the two events is different, and their boundary is the southern edge of the 2004 rupture area, which is also consistent with the southern edge of the Andaman microplate. The viscosity of the shear zone is determined to be 2×1017  Pa·s in the northern segment, 1016  Pa·s at shallow depths (≤20 km) and 2×1018  Pa·s at greater depths (>20 km) in the southern segment. Afterslip of the 2004 event takes place mostly surrounding the rupture area and is up to 3.2 m within 10 yr after the earthquake. Afterslip of the 2005 event takes place mostly up-dip of the rupture and is up to 4.3 m. The viscosity of the weakened areas in the Andaman spreading center and Toba volcano is determined to be 1018  Pa·s and 3×1018  Pa·s, respectively. A test model with the oceanic asthenosphere extending to depths up to 110 km better explains the vertical motion in the near field.
Land, Labor, and Relationality: A Critical Engagement of Marx and Indigenous Studies
Authors: Lindquist Kelsey
Published: July 2024

In this article, the author places Marxist scholarship in conversation with critical Indigenous theory, outlining Marx's insights and tracing recent development within Marxist-feminist literature before critiquing this scholarship from the perspective of critical Indigenous theory. The author argues that the failure to attend to Indigenous sovereignties is a critical limitation undermining attempts to theorize multiple systems of oppression, demonstrating that critical Indigenous theory, with its more expansive understanding of relationality, not only addresses this limitation but also extends the theorization beyond the logic of capital.
