Authors: Wiklund Maja , Larsson Jenny , Rapp Martin 
Published: November 2024

AbstractA female Swedish Elkhound was presented by the breeder at a referring clinic due to a swelling in the left mandibular area. The mass continued to grow, and at the age of 2 months the dog was referred to the hospital. Computed tomography was used for diagnostics of a unilateral external aneurysm of the left vena facialis and vena lingualis with a suspected centrally mineralised thrombus was made. One month later, the dog underwent surgery for removal of the aneurysm. This case describes the diagnostics, the perioperative anaesthetic considerations and anaesthetic management for surgery to remove the aneurysm where concerns regarding the young age and the risk of intraoperative haemorrhage were addressed. Premedication consisted of methadone and dexmedetomidine, general anaesthesia was induced using propofol and ketamine as co‐induction agents and maintained using isoflurane. There were no intraoperative anaesthetic complications; however, a postoperative surgical complication in the form of a seroma developed.

Abstract

Objective
Presentation and description of percutaneous sacroiliac (SI) screw fixation with the use of a 3D robot-assisted image-guided navigation system and the clinical outcome of this technique.

Indications
Pelvic fractures involving the posterior pelvis.

Contraindications
Patients not suited for surgery.

Surgical technique
Planning the screws on the diagnostic computer tomogram (CT). Matching with a low-dose CT in the operating room. Lateral incision. Verify the guidewire position with the personalized inlet and outlet views. After correct positioning, place a cannulated screw over the guidewire. For fragility fractures, augmentation is recommended. Finish the surgery with a final 3D scan to confirm correct placement of the screws and cement.

Postoperative management
Direct postoperative mobilization with pain-adapted full weight-bearing.

Results
Data of 141 patients between January 2018 and August 2022 were analyzed (average age 82 ± 10 years, 89% female). Most of the fractures were type II fragility fractures of the pelvis (FFP; 75%). The median hospital stay was 12 ± 7 days and the median surgery duration for a unilateral SI screw was 26 min. In total 221 S1 screws and 17 S2 screws were applied. No screws showed signs of loosening or migration. Of the five suboptimally placed screws, one screw was removed due to sensory impairment. All patients with cement leakage remained without symptoms.

Conclusion
The surgical technique with the use of a 3D robot-assisted image-guided navigation system is a technique for safe fixation of dorsal fragility fractures of the pelvis and is associated with fewer complications.
Self-Management Support (SMS) in Transition: The Case of Osteoporosis Management Support in a Chinese Hospital
Authors: Huang Jinling , Ding Xianghua 
Published: November 2024

AbstractSelf-management has become increasingly important with the growing population living with chronic conditions. Self-Management Support (SMS) provided in healthcare systems is essential for its success. While prior research mainly focuses on Western countries, this paper presents a study of SMS practices for osteoporosis management as part of a Whole Course Management (WCM) program recently implemented in the healthcare system in China, which features a new role called case manager in the hospital dedicated to SMS and related coordination. Based on interviews with 22 participants, including one case manager, two physicians, three nurses, seven patients, and nine caregivers, we highlight the importance of the role of case manager in promoting awareness of osteoporosis and self-management, integrated care coordination, and emotional support. At the same time, it also reveals challenges and promising directions to make SMS more effective, mainly in terms of self-management education, active patient involvement, and coordination among the care network. We ended by reflecting on our findings and discussing implications for SMS and the design of ICTs.
Development of a simple test to quantify the consolidation properties of liquefied granular materials
Authors: Tauskela L. , Adamidis O. , Take W. A. 
Published: November 2024

AbstractLiquefaction can have devastating consequences by causing increased mobility of debris flows, tailings dam breaches, and settlement following seismic shaking. Observations on the consolidation behaviour of liquefied soils in 1-g or centrifuge shake table tests have permitted significant advancements in analytical and numerical methods to predict the rate and magnitude of consolidation settlement. However, advanced consolidation models introduce material parameters which are currently difficult to define quickly and at low cost. The objective of this paper is to demonstrate the development of a simple, low-cost test that can be used to quickly estimate the spatially and temporally varying coefficient of consolidation, which controls post-liquefaction settlements. Using the proposed simple setup, experiments were conducted on four uniformly graded sands of varying grain size and on one well-graded mixture. A range of analytical and numerical approaches from literature were assessed for their ability to back-analyse the observed pore pressure dissipation and settlement. Estimated values for the coefficient of consolidation were comparable between models and estimates of surface settlement matched well the experimental results. The simplicity of the proposed test combined with its low-cost and mobile nature, raise significant possibilities for quick estimations of the evolution of the coefficient of consolidation post-liquefaction.

Published: November 2024

AbstractDuplex stainless steels provide a desirable combination of corrosion resistance, strength and toughness. Additive manufacturing of duplex stainless steels can be challenging due to high cooling rates and repeated reheating, which can produce detrimental microstructural constituents. In this study, a coaxial directed energy deposition system with laser and wire was used to deposit 2205, 2209 and 2509 duplex stainless steels. Corrosion resistance, strength and impact toughness in both as-built and solution annealed condition was tested and the microstructure was characterized. Solution annealing improved impact toughness considerably, produced a slight increase in corrosion resistance and a slight decrease in tensile strength. The 2205 material surpassed all common requirements and exhibited better corrosion resistance than 2209 due to less segregation between austenite and ferrite. Segregation of alloying elements was lower in intragranular austenite than grain boundary allotriomorph and Widmanstätten austenite. The 2209 and 2509 materials provided relatively low strength, especially in the solution annealed condition. For the 2509 material, sigma phase caused low as-built corrosion resistance and impact toughness. Overmatching welding consumables were found to be less suitable as feedstock for additive manufacturing due to high austenite content in the deposited material and lower corrosion resistance than conventional duplex compositions.
The Impact of Domestic Violence on the experience of being a mother: a systematic review of the subjective accounts of survivors

AbstractDomestic violence (DV) is still a silent public health pandemic globally, more so during the COVID-19 pandemic. Domestic abuse has a well-documented impact on women and its potential transgenerational consequences for their children. However, the influence of DV on a survivor's experience as a parent is rarely studied, especially in developing nations. Through a systematic review, this study aimed to examine and synthesise current global research on DV survivors' experiences regarding their parenting capacities. The objective was to understand how DV survivors perceive how their parenting capacities were impacted by the experience of DV. Five databases were searched between the periods 2010 to 2020. Fourteen studies met the inclusion criteria. Through a thematic analysis of the included articles, three core themes emerged: first, the mothers’ state of psychosocial and physical health, exacerbated or associated with the DV experience, holds association with their perceived capacity within a parental role. Second, the influence of DV on motherhood is not necessarily predictive of negative parenting practices but somewhat contingent on the mothers’ ability to mobilise supportive internal and external resources, which are often restricted and disrupted by the abusive partner. Last, decisions to leave the abusive partner are complex and subjectively reasoned by the mothers, with a common intention to protect the family. These findings suggest that more comprehensive support and preventative interventions are needed in local communities to create supportive environments that are accessible to mothers who parent in the context of DV.
Maternal narcissism and child maladjustment: a dyadic study

Published: November 2024

AbstractThe goal of the present study was to examine the association between a mother’s narcissistic traits (grandiose or vulnerable) and her child maladjustment, while exploring the possible mediating role of the mother’s parenting style (i.e., accepting or rejecting) and her perception of the child as difficult. Results from a three-step regression model using a sample of 252 mother-child dyads indicated that only mother’s vulnerable narcissism, but not grandiose narcissism, was significantly associated with child maladjustment. This association, however, was mediated by mother’s perception of her child as difficult, suggesting an intricate interplay between mothers’ personality traits and children’s psychological characteristics. In addition, rejecting parenting did not significantly mediate the association between maternal vulnerable narcissism and child maladjustment but rather, also seemed to be by itself mediated by mother’s perception of her child as difficult, calling for further consideration of mechanisms that may underlie the long documented direct association between parenting behaviors and child outcomes. Theoretically, our findings imply that previous assumptions about direct influences of parenting styles on child outcomes may be explained by underlying mechanisms, such as a mother’s perception of her child. Clinically, our findings have implications for developing interventions aimed at improving child well-being, particularly in families where maternal vulnerable narcissism exists, by focusing on maternal perceptions and providing emotional support.

Published: November 2024

AbstractPolymeric microwave actuators combining tissue-like softness with programmable microwave-responsive deformation hold great promise for mobile intelligent devices and bionic soft robots. However, their application is challenged by restricted electromagnetic sensitivity and intricate sensing coupling. In this study, a sensitized polymeric microwave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx (MXene). Compared to the initial counterpart, the hybrid polymer exhibits unique space-charge polarization and interfacial polarization, resulting in significant improvements of 230% in the dielectric loss factor and 830% in the apparent efficiency of electromagnetic energy harvest. The sensitized microwave actuation demonstrates as the shortened response time of nearly 10 s, which is merely 13% of that for the initial shape memory polymer. Moreover, the ultra-low content of MXene (up to 0.15 wt%) benefits for maintaining the actuation potential of the hybrid polymer. An innovative self-powered sensing prototype that combines driving and piezoelectric polymers is developed, which generates real-time electric potential feedback (open-circuit potential of ~ 3 mV) during actuation. The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approach for developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.

Abstract
This study investigated the validity and sensitivity of a custom-made shoelace tensile testing system. The aim was to analyze the distribution pattern of shoelace tension in different positions and under different tightness levels during running. Mechanical tests were conducted using 16 weights, and various statistical analyses, including linear regression, Bland-Altman plots, coefficient of variation, and intraclass correlation coefficient, were performed to assess the system’s validity. Fifteen male amateur runners participated in the study, and three conditions (loose, comfortable, and tight) were measured during an upright stance. The system utilized VICON motion systems, a Kistler force plate, and a Photoelectric gate speed measurement system. Results showed a linear relationship between voltage and load at the three sensors (R2 ≥ 0.9997). Bland-Altman plots demonstrated 95% prediction intervals within ± 1.96SD from zero for all sensors. The average coefficient of variation for each sensor was less than 0.38%. Intraclass correlation coefficient values were larger than 0.999 (p<0.0001) for each sensor. The peak tension of the front shoelace was greater than that of the front and middle when the shoelace was loose and tight. The rear shoelace had the highest tension force. The study also found that shoelace tension varied throughout the gait cycle during running. Overall, this research provides a novel and validated method for measuring shoelace tensile stress, which has implications for developing automatic shoelace fastening systems.

Authors: Nes Kjersti , Colen Liesbeth , Ciaian Pavel 
Published: November 2024

AbstractCompetition and power imbalances in the food chain are under increased scrutiny from policy makers. We assess the competitive conditions in the EU food sector, using firm-level accounting data to examine firm size distributions and market concentration (for 10 countries), and production-function-derived markups (for 7 countries) for food manufacturing, retail, and wholesale industries. Key findings include the following: (i) most firms are small, but larger firms generate most turnover; (ii) concentration is notable in certain subsectors (25% of retail/wholesale and 50% manufacturing subsectors); (iii) the correlation between turnover size, markups, and concentration at subsector level is weak. We discuss the implications for the use of turnover-based classification in the EU policy initiative on unfair trading practices.

Authors: Moon Chung-in , Yeon Wonho 
Published: November 2024

Abstract
The current conflictual dynamics underlying high-tech rivalry between China and the United States and the management of collateral damages by middle-power countries emanate from the clashes of techno-statecraft. Each country’s pursuit of technological superiority for its own prosperity, security, and prestige through deep and wide state intervention has aggravated the situation. Against this backdrop, our paper attempts to elucidate the dynamics of techno-statecraft of China, the United States, and South Korea. First, we examined the concept of techno-statecraft, which can be differentiated from that of economic statecraft, as an analytical framework of the paper. Second, we looked into China’s technological challenge as shaped by its techno-statecraft. Third, we traced the American threat perception of China’s technological rise and its techno-statecraft response. Fourth, the paper discussed the dilemmas Asian countries are currently facing and their choices through a case study of South Korea. Finally, it draws some theoretical, empirical, and policy implications.

Abstract
Individuals may experience health issues attributable to environmental pollution, sedentary lifestyles, and unhealthy dietary habits. In response, numerous non-pharmaceutical treatments and techniques have emerged, with therapy mud being one such approach. The primary aim of this research was to analyze the chemical and mineralogical compositions of peloids obtained from six salt lakes: Taigan (LI), Duruu (LII), Khadaasan (LIII), Ikhes (LIV), Tonkhil (LV), and Khulmaa (LVI) in the Gobi-Altai province of Mongolia. Sample analyses involved X-ray diffraction for mineralogical assessment and inductively coupled plasma-mass spectrometry (Agilent Technologies 7800 series in Canada) for determining the chemical composition of the solid phase. Among essential macro- and microelements, Mg, Cа, Na, K, Sr, Ga, Mo, and Se had been leached from peloid to artificial sweat. Sn (0.01 μg g–1) at LIV and LVI lakes and Cu (0.01 μg g–1) at LV lake transferred from peloids to sweat, but no mobility of these elements in other peloids was detected. Li (0.02–0.04 μg g–1) was adsorbed from the sweat to potential peloids in LV, LIV, LIII, and LI lakes, while As (0.04–0.09 μg g–1) leached from peloids to sweat in all lakes except for LII. Zn (0.01 μg g–1) and Cr (0.04 μg g–1) transferred from the sweat to peloids in all lakes. Macroelements (Na, K, Ca, and Mg) and microelements (Mo, Se), which are essential for the human body, leached from the peloid to sweat. However, the mobility of toxic elements was minimal. Among micro-elements, the transition of Sr occurred the most, which can be explained by the Sr content in the peloid.

Abstract
The increasing contamination of water by organic dyes causes water pollution in the enviroment. Factories discharge untreated effluents into nearby water courses adding to the existing water pollution; this poses a significant environmental challenge. Hence there is a pressing demand to develop efficient technology for wastewater treatment, and photocatalysis has emerged as an advanced oxidation process with a green chemical approach for such treatment. This study aims to synthesize montmorillonite/TiO2 (Mnt/TiO2) photocatalysts and clarify the effect of montmorillonite content on the photodegradation of the organic dye rhodamine B (RhB). Mnt/TiO2 was prepared by a chemical method with various mass ratios of mMnt:mTiO2 based on the cation exchange capacity (CEC) of Mnt. The physicochemical properties of the samples prepared were determined by the following methods: energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The photocatalytic degradation efficiency of the RhB solution of Mnt/TiO2 was investigated by UV-Vis spectroscopy under UVC irradiation. Liquid chromatography-mass spectrometry (LCMS) was used to identify the photocatalytic by-products. The results showed that the structure of the nanocomposites has a ‘house-of-cards’ form with TiO2 nanoparticles randomly distributed on the surface and sheets of clay minerals. The best mass ratio of mMnt:mTiO2 is 10:1, corresponding to a 10 ppm RhB solution decolorization efficiency of 91.5% in 210 min. In this study, Mnt/TiO2 successfully cleaved the dye chromophore structure and broke the RhB rings into small and broken-ring compounds.

Abstract
With the over-use of tetracycline (TC) and its ultimate accumulation in aquatic systems, the demand for TC removal from contaminated water is increasing due to its severe threat to public health. Clay minerals have attracted great attention as low-cost adsorbents for controlling water pollution. The objective of the present study was to measure the adsorption behavior and mechanisms of TC on allophane, a nanosized clay mineral with a hollow spherical structure; to highlight the advantage of the allophane nanostructure, a further objective was to compare allophane with halloysite and montmorillonite, which have nanostructures that differ from allophane. Structural features and surface physicochemical properties were characterized by transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), zeta potential, N2-physisorption, and acid–base titration. The adsorption data showed that TC adsorption followed the pseudo-second order and Langmuir models. The adsorption was pH dependent, as all three clay minerals performed better under neutral to weakly alkaline conditions and maintained high adsorption performance in the presence of co-existing Na+/K+/Ca2+/Mg2+ cations. Regeneration of the adsorbent was excellent, with efficiencies exceeding 75% after five recycles. By comparison, allophane always exhibited the greatest adsorption capacity, up to 796 mg g–1 at ~pH 9. The TC adsorption on allophane and halloysite was dominated by inner-sphere complexation, together with a small amount of electrostatic adsorption, while that on montmorillonite involved mainly interlayer cation exchange. The findings provide insights into the effects of nanostructures of clay minerals on their TC adsorption performance and highlight the huge potential of allophane as an efficient and inexpensive adsorbent for TC removal.
