Published: November 2024

AbstractAqueous biphasic systems (ABSs) with water‐in‐salt electrolytes are gaining significant attention for their role in aqueous biphasic interphase studies, particularly in energy storage devices. Aqueous salt‐salt biphasic electrolytes are considered a promising alternative to replace traditional liquid electrolytes commonly used in battery technologies, for example, membrane‐less redox flow batteries, owing to their low cost and high ionic conductivity. However, the stability of the interphase over time must be considered, as it can impact the long‐term electrochemical performance in various applications. This study reports the unstable interfacial behavior of lithium bis(trifluoro‐methanesulfonyl)imide and lithium chloride (LiTFSI‐LiCl) system using an optical microscope and electrochemical properties. These observations reveal the liquid‐liquid instability phenomenon at the interphase over time. Moreover, this research discovers and analyzes the unwanted solid phase formation at the LiTFSI‐LiCl interphase. This study not only contributes to fundamental knowledge in interfacial science but also holds significant implications for developing novel applications reliant on ABSs stability.

Published: November 2024

ABSTRACTA sensitive and straightforward method for determining various species of selenium (Se) in Chinese wolfberry and Se‐rich foliar fertilizers was established using high‐performance liquid chromatography—inductively coupled plasma mass spectrometry. The application of this method proved effective in quantifying both organic and inorganic Se in 64 batches of Chinese wolfberry and their soaking solutions, along with five types of foliar fertilizer. This investigation revealed notable variations in the Se content among different batches of Chinese wolfberry, with selenomethionine (SeMet) emerging as the predominant form. Furthermore, the application of Se‐enriched foliar fertilizer led to the deposition of surface Se residues on the surface of Chinese wolfberry, primarily in the form of Se(VI) and Se(IV). This observation has implications for the proportion of organic Se in the plants (Chinese wolfberry), as organic Se, particularly SeMet, exhibits greater bioavailability and lower toxicity than its inorganic counterparts. Therefore, augmenting the organic Se content in the plant may confer greater benefits for the utilization of Chinese wolfberry in promoting human health.

Published: November 2024

AbstractThe growing interest in sustainable biopolymers has highlighted cocoyam starch as a promising material for functional biodegradable packaging film development. This study evaluates its physicochemical, structural, thermal, rheological, and mechanical properties to determine its suitability for packaging. Cocoyam starch contains moisture (9.15%), protein (0.68%), lipid (0.57%), ash (2.82%), and resistant starch (5.61%), offering moderate digestibility. Total soluble phenolic compounds are quantified at 50.56 mg GAE·100 g−1 of starch, which influences the physicochemical properties. Cocoyam starch presented a semi‐crystalline structure comprising both Type A and B starches, along with monohydrated calcium oxalate crystals. The gelatinization temperature is determined to be 65.81 °C, with an associated gelatinization enthalpy of 15.38 J g−1. Gel retrogradation exhibits a rate of 38.52%. Rheological properties reveal a high peak viscosity and breakdown, suggestive of a high amylopectin content in the starch. Cocoyam starch films demonstrate variations in thickness and neutral instrumental color parameters. Mechanical analysis reveals that these films have lower tensile strength but higher elongation to rupture compared to cassava starch films, likely due to the intermolecular connections formed by cocoyam starch. Crystallography patterns of films indicate structural transformations, including calcium oxalate phases and semi‐crystalline structures, underscoring their potential applications in biodegradable packaging materials.
The effects of longitudinal joint assembly imperfections on the internal forces in segmental linings
Authors: Rauch Fabian , Fischer Oliver 
Published: November 2024

AbstractDuring the assembly of concrete segments into a tunnel lining, small geometric imperfections are unavoidable. In the longitudinal joints, they lead to contact deficiencies, which affect the eccentricities of the forces transferred through them. This influences the development of internal forces along the lining's circumference. However, it is often not realistically considered in structural calculations. In this paper, the effects of longitudinal joints assembly imperfections on the lining's internal forces were investigated by employing finite element models for various lining configurations. The results show that assembly imperfections have an unfavorable effect on the internal forces in most cases. Depending on the loading situation, this can lead to more required reinforcement and higher utilization ratios in the segments field and joints compared to perfectly assembled linings. Stiffer and less deformable configurations are at higher risk of experiencing more severe effects. In systems at risk, an individual assessment is recommendable. Therefore, a simplified method is introduced that requires a significantly reduced modeling effort and calculation time and lower software capabilities.
Culturally and linguistically responsive pedagogy: Examining teachers' conceptualizations of affirmative instructional practices for multilingual learners
Authors: Wesley‐Nero Sabrina , Donley Kevin 
Published: November 2024

AbstractA culturally and linguistically responsive teaching force is a critical element in the pursuit of educational justice (Levinson, 2022). Culturally and linguistically responsive pedagogy (CLRP) can disrupt patterns of marginalization and strengthen students' ability to thrive in schools (Akiba et al., 2010). In this study, the researchers examine how preservice and in‐service teachers understand and enact CLRP when teaching multilingual learners (MLs). Drawing on post‐observation reflection data with six preservice teacher residents and post‐observation interviews with 11 in‐service teachers across multiple classroom contexts and grade levels, the authors demonstrate how teachers enact responsive pedagogies by (1) implementing culturally relevant curricula, (2) embracing students' full communicative repertoires, (3) dismantling deficit‐based perspectives of MLs, and (4) practicing critical consciousness in teaching and learning.

Published: November 2024

AbstractThere has been little quantitative research on the impact of specialized teacher preparation for working with multilingual students. Yet districts, states, and the U.S. Department of Education are investing to increase the number of teachers with this specialized preparation. This article explores challenges in conducting research on this topic through discussion of an impact evaluation for Teachers Educating All Multilingual Students (TEAMS), a teacher professional development program funded by a National Professional Development grant. The researchers first explore the results of our quasi‐experimental study, showing that teachers' participation in TEAMS positively impacted English learner students' English language arts assessment outcomes. They then explore tensions in meeting federal impact evaluation standards, including challenges with participant selection, capturing the impact of family and community engagement, understanding shifts in advocacy and teacher leadership, and documenting impact for dual language teachers. The authors discuss implications for research, policy, and practice.

AbstractA comparative study was conducted on the adsorption capacity of Cocos nucifera shell‐activated carbon (CNSA) and Cocos nucifera shell‐activated carbon@TiO2 composite (CNSA‐TiO2) for para‐nitroaniline in an aqueous medium. The CNSA was carbonized at 500 °C and activated with 1 M HNO3 while the CNSA‐TiO2 composite was prepared by wet impregnation method. The prepared adsorbents were characterized through Brunauer–Emmett–Teller (BET), energy dispersive X‐ray (EDX) spectroscopy, Fourier‐transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). The BET‐surface area of CNSA‐TiO2 (748.96 m2/g) was established to be larger than CNSA (574.21 m2/g), however both materials are mesoporous. The effects of initial p‐NA concentration, pH, adsorbent dosage, contact time, and temperature, were explored for both adsorbents. The results showed that the adsorption operating parameters influenced the adsorption process except for temperature, with maximum adsorption of 38.26 and 38.36 mg/g for CNSA and CNSA‐TiO2, respectively. Freundlich, Langmuir, Temkin, and Dubinin‐Radushkevich isotherms were tested on the adsorption data, and the adsorption process of both adsorbents followed the Freundlich isotherm model (R2 > 0.988). Among the kinetic models studied, the pseudo‐second‐order model (R2 = 1) best described both processes. The thermodynamic parameters such as ∆G °, ∆H ° and ∆S ° were calculated. The process was exothermic, spontaneous and feasible.

Published: November 2024

ABSTRACTBackgroundKlebsiella pneumoniae is an opportunistic pathogen that causes severe infections in humans and animals. Nonetheless, little is known about the molecular epidemiology of mastitis‐associated K. pneumoniae in dairy cows.ObjectivesThis cross‐sectional study investigated the epidemiology and antimicrobial resistance (AMR) of K. pneumoniae in 700 milk samples collected from cows with and without mastitis in seven dairy farms in Xinjiang, China.MethodsK. pneumoniae was identified by PCR amplification of the khe gene and the automated VITEK 2 Compact System. Resistance against 18 antimicrobial agents was analysed by broth microdilution. Forty‐four new strains were sequenced by whole‐genome sequencing (WGS). WGS data were searched for the presence of AMR and virulence genes. Genotypic characterization was performed by multilocus sequence typing and the analysis of wzi allele types and K and O antigens.ResultsK. pneumoniae isolates were found in 131 samples (18.7%). The prevalence of K. pneumoniae in cows with clinical and subclinical mastitis was higher than that in healthy cows (27.1%, 23.2% and 7.3%, respectively). WGS identified 27 wzi allele types, 16 K antigen serotypes, 6 O antigen serotypes and 25 sequence types. Phylogenetic analysis showed high genomic diversity in K. pneumoniae. The rate of resistance to tetracycline and cefazolin was 39.7% and 31.3%, and the multidrug resistance rate was 26.7%. Thirty‐nine AMR genes conferring resistance to nine antibiotic classes and 57 virulence genes were identified in new isolates. AMR and virulence genes were more prevalent in known human isolates than in new isolates.ConclusionsThese results improve our understanding of the epidemiology and resistance status of mastitis‐associated K. pneumoniae strains. The emergence and spread of multidrug‐resistant K. pneumoniae strains threaten food safety and public health.

ABSTRACTBackgroundPeste des petits ruminants (PPR) is a disease with high morbidity and mortality in small ruminants. A clinical report of this disease in camels has been made in Iran; however, no accurate information is available about infection with this virus in the camel population of Iran.ObjectivesThis study was designed and conducted to detect any trace of seroconversion in dromedary camels in Iran.MethodsA total of 100 serum samples were collected from a slaughterhouse in Khorasan Razavi Province and analysed using a competitive enzyme‐linked immunosorbent assay to detect antibodies against the PPR virus.ResultsThe results of this study indicated that the frequency of PPR virus exposure in camels in Khorasan Razavi Province was 3% (3 positive cases out of 100 camels). All the positive cases were female.ConclusionThe seroconversion without any history of clinical disease among these camels indicated their exposure to the PPR virus in this region and their resistance to clinical disease. The resistance and sensitivity to this disease in camels have yet not been fully determined and require further studies. However, stressful risk factors such as transportation may contribute to the occurrence of clinical forms of PPR in camels. The detection of antibodies against the PPR virus in camels in this study reveals the fact that camels may be considerable contributors to the epidemiology of PPR in Iran.

AbstractPatients with kidney failure need dialysis or a kidney transplant to survive. Living donor kidney transplantation (LDKT) is the best therapeutic option, yet global rates of LDKT have minimally increased, and there are disparities in access. The need for a systems approach to improvement has been highlighted. We aimed to understand what elements of a relatively large health system interact to deliver LDKT and act as facilitators or barriers. This was an exploratory case study of Ontario, the most populous province in Canada that conducts 600–700 kidney transplantations annually, of which ~30% are LDKT. Data collection entailed interviews with multiple stakeholders (n = 37), and document review (n = 29) served as a means of triangulating the data. Data were analyzed using inductive thematic analysis. A multicomponent intervention to facilitate kidney transplantation was simultaneously being conducted which allowed us to capture its impact (EnAKT‐LKD). Eight themes were identified, that were separated into facilitators and barriers. Centralized leadership, directed resource deployment, dynamic communities of practice, and informal collaborations between various elements of the health system were found to facilitate LDKT. Barriers were inadequate donor and patient resources to support equitable access, lengthy and poorly coordinated workups for donors and recipients, and issues of jurisdictional control and competition for resources. The EnAKT‐LKD initiative was described as having boosted resource deployment and collaborative capacity and improved strategic alliances by establishing communities of practice. This case study has identified how individual elements in a health system interact to facilitate and impede the delivery of a therapy to patients.

Published: November 2024

AbstractThe concrete with different fibre and ratio can lead to different performance. This paper studies the mechanical properties of concrete by changing the ratio of PVA fibre and steel fibre. Three kinds of ratio of the PVA fibre and steel fibre are studied. They are 0% PVA fibre and 0% steel fibre, 0.25% PVA fibre and 0.75% steel fibre, 0.5% PVA fibre and 0.5% steel fibre. The compressive strength, flexural strength, bending toughness are tested. The test result shows that the compressive strength of the P0.25S0.75 increases. While the group of P0.5S0.5 shows a little range of decreasing. The 28d flexural strength of P0.25S0.75 and P0.5S0.5 increases 2.3 and 30.2% respectively. The loading-deflection curves of P0.25S0.75 and P0.5S0.5 all appear strain harden property. By the mixing amount of the PVA fibre increasing, the cracking strength and limitation bearing ability can all be enhanced. The areas under the curve enlarge and the toughness of the concrete are enhanced. The bending toughness of P0.5S0.5 is much better than the P0.25S0.75 but the difference is not very large.

AbstractAiming at the characteristics of structural backfill engineering, combined with the backfill performance requirements of subway stations, and taking backfill material fluidity, crystalline body strength, seepage resistance and volumetric stability as the main assessment indexes, a self-compacting and high seepage-resistant backfill material has been researched and prepared by taking the bulk solid waste cinder slag and fly ash as the main raw materials, blast furnace slag powder as the dope, and cement as the curing component. Compared with traditional backfill, the material has self-leveling characteristics and good backfill uniformity. The 28-day compressive strength of the material can reach 10.2–21.3 MPa, which exceeds that of C10 concrete. The material has good seepage resistance, seepage pressure up to 0.7–0.8 MPa, good volume stability, 28 d shrinkage rate of 10–4 orders of magnitude. The research results were applied in the backfilling project of Xintun Station of Qingdao Metro Line 6, which showed excellent mobility, greatly saving construction cost and time, and the test results met the project requirements. This study takes into account the requirements of material performance and the proportion of solid waste mixing, and under the premise of meeting the engineering requirements of backfill materials, it can effectively absorb fly ash, slag and other bulk solid waste, and has achieved good economic and environmental benefits.

Zusammenfassung

Fragestellung
Die individuelle Mobilität im Straßenverkehr hat in Deutschland, sowohl individuell als auch sozioökonomisch betrachtet, einen hohen Stellenwert. Insbesondere Erkrankungen und Verletzungen im Bereich des muskuloskeletalen Systems können jedoch temporär zu Beeinträchtigungen führen. Ziel dieser prospektiven Patientenbefragung war es zu erfassen, wie die Patienten ihre Fahrtauglichkeit während einer Verletzung und damit verbundenen Ruhigstellung einschätzten und auf welcher Grundlage die Entscheidung über die Fahrtauglichkeit seitens der Patienten getroffen wurde.

Material und Methoden
Anhand eines systematischen Fragebogens wurden insgesamt 100 Patienten mit einer orthopädischen/unfallchirurgischen Diagnose und einer damit verbundenen Gelenkruhigstellung analysiert. Neben persönlichen Daten und der Verletzungen/Erkrankungen wurde eine Analyse zur Risikobereitschaft durchgeführt, und die Patienten wurden zu ihrem Wissen bezüglich der Fahrtauglichkeit befragt. Abschließend wurde erfasst, welche Patienten aus welchen Gründen trotz Ruhigstellung ein Kraftfahrzeug (Kfz) geführt haben.

Ergebnisse
Insgesamt gaben 40,2 % an, Kenntnis über das geltende Recht hinsichtlich der Fahrtauglichkeit zu haben. Weiterhin schätzten 55,6 % den behandelnden Arzt als Verantwortlichen bezüglich der Entscheidung über die Fahrtauglichkeit ein. Die Patienten, die ein Kfz führten, gaben eine höhere sowohl private als auch berufliche Abhängigkeit vom Kfz an (privat: 60,6 % vs. 45,7 %; beruflich: 48,5 % vs. 36,1 %). In der Patientengruppe, die ein Kfz während der Ruhigstellung führte, war insgesamt seltener eine Fraktur der Grund der Ruhigstellung (33,3 % vs. 51,0 %).

Diskussion
Insgesamt schätzte das Patientenkollektiv seine Kenntnis über die Gesetzeslage als gering ein und sah den behandelnden Arzt in der Mehrzahl in der Entscheidungsverantwortung hinsichtlich der Fahrtauglichkeit. Die Patienten, die ein Kraftfahrzeug während der Ruhigstellung führten, gaben eine höhere private als auch berufliche Abhängigkeit vom Führen eines Kfz an. Gleichzeitig hatte die Verletzungsschwere einen Einfluss auf die Entscheidung, sodass Patienten mit Frakturen eine Fahrt mit einem Kfz eher vermieden. Weitere Studien insbesondere auf biomechanischer Ebene sind erforderlich, um für den Arzt eine bessere Grundlage für die Entscheidungsfindung hinsichtlich der Fahrtauglichkeit bei orthopädischen/unfallchirurgischen Erkrankungen zu gewährleisten.
