Published: April 2023

AbstractThough universities have offered online education options since the 1990s, the coronavirus (COVID‐19) pandemic led to increased online course development and implementation worldwide. Transitioning to online learning during the pandemic created challenges and opportunities for instructors and students alike, especially in the soil and environmental sciences, where laboratory and field work is essential for training students. Our review of the available literature and the authors' personal experiences suggests that many students struggled with the transition, with a lack of adequate internet access representing a significant barrier for many university students. Similarly, some instructors struggled with transitioning away from in‐person learning, while others took the opportunity to create novel resources, institute new learning frameworks, and develop unique online course content. Here we seek to describe some of the major challenges and benefits related to the transition to online learning during COVID‐19 as well as the efficacy of different online course types, including the perspectives of both university students and instructors based on both the authors’ experience at three universities in two countries and on the published literature. Based on these findings, we also make recommendations regarding future online course development in soil and environmental science fields.

Published: April 2023

AbstractBamboo scrimber and carbonized bamboo scrimber are new green and sustainable materials that have recently gained widespread attention and application in construction and other fields. However, their production is accompanied by the generation of a large number of residues, such as bamboo particles (BPs) and carbonized bamboo particles (CBPs). In this study, we used BPs and CBPs as reinforcing phases and phenol‐formaldehyde (PF) resin, which is mainly used to manufacture bamboo scrimber, as the matrix to prepare bamboo particle composites (BPCs). The physical, flexural, and thermal properties of the composites were characterized, and the activation energies were analyzed and compared using Kissinger and Flynn–Wall–Ozawa (FWO) methods. The results showed that the blending system composed of two types of bamboo processing residues demonstrated significant composite performance enhancement. The BPC performance met the standard requirements for furniture particleboard, and the potential exists to further improve its thermal properties. This study fills the current gap in the kinetic analysis of BPCs and contributes to the further understanding and application of this material, thus facilitating the industrial use of bamboo processing residues and bamboo scrimber for sustainable development and economic benefits.

AbstractAdditive manufacturing of fabrics is an emerging research topic with potential applications in several industries including high performance wearable products and high‐temperature textiles. Therefore, thermal, mechanical, and viscoelastic properties of such fabrics need to be determined. In this research, the thermomechanical behavior of additively manufactured plain weave fabrics at and above glass transition temperature ( is studied. The time‐dependent mechanical response using a viscoelastic material model is represented by a Prony series as a function of frequency (f). Unit cells of plain weave fabrics are additively manufactured using poly(lactic) acid (PLA). Tensile and compression tests were performed on unit cells in a thermal environment using dynamic mechanical analysis (DMA). A multiphysics finite element model is implemented to duplicate the experimental setup. The experimental results are compared with that of computational results. The relative error percentages in the peak forces at each temperature are 23.60% at 60°C, −8.85% at 65°C, and −6.25% at 70°C. A better agreement in peak forces is seen for unit cells above Tg. The computational model developed for unit cells is used to predict the thermomechanical‐viscoelastic response of large additively manufactured fabric structures which is difficult to evaluate experimentally.

Published: April 2023

AbstractIntroductionPostural instability and gait impairments are common in people with PD, both of which have a negative effect on their quality of life. Systematic reviews have demonstrated benefits of using exergaming in enhancing these outcomes. However, there is no consensus over whether exergaming therapy is better than conventional physical therapy for enhancing gait, balance, and quality of life. Objectives: The aim of this overview is to systematically synthesize and evaluate the available evidence found in published systematic reviews and meta‐analyses, on the effects of exergaming therapy on balance, gait, and quality of life, compared to conventional physical therapy or no intervention.MethodsThis overview was reported in accordance with the statement of Preferred Reporting Items for Systematic Reviews and Meta‐analysis (PRISMA). A comprehensive search was carried out in nine databases. Two reviewers independently extracted data using a standardized forms and the search strategy included terms related to intervention, population, and study type. The methodological quality of the included systematic reviews/meta‐analysis (SRs/Mas) was evaluated using the “A Measurement Tool to Assess Systematic Reviews 2” (AMSTAR‐2). The “Grading of Recommendations Assessment, Development and Evaluation” (GRADE) was used to assess the quality of the evidence. The risk of bias assessment was performed using the “Risk Of Bias In Systematic Reviews” (ROBIS). PROSPERO registration number: CRD42021238131.Results112 SRs/MAs were found and nine of them were selected. Six reviews were rated as very low methodological quality and three reviews as low methodological quality. Five reviews were classified with low risk of bias and four reviews with high risk of bias. Most of the SR/MAs demonstrated significant effects on balance favoring exergaming therapy over conventional therapy, however those studies had been rated as very low quality of evidence. Inconclusive results were found for the quality of life and gait outcomes.ConclusionExergaming therapy shows promise for the rehabilitation of PD. However, this overview was unable to conclude with certainty that exergaming therapy is superior to conventional physical therapy in improving gait, balance, or quality of life in people with PD. The effectiveness of exergaming therapy in the treatment of people with PD still need to be verified by high‐quality studies.

AbstractStability, long lifetime, resilience against clogging, low noise, and low cost are five critical cornerstones of solid‐state nanopore technology. Here, a fabrication protocol is described wherein >1 million events are obtained from a single solid‐state nanopore with both DNA and protein at the highest available lowpass filter (LPF, 100 kHz) of the Axopatch 200B–the highest event count mentioned in literature. Moreover, a total of ≈8.1 million events are reported in this work encompassing the two analyte classes. With the 100 kHz LPF, the temporally attenuated population is negligible while with the more ubiquitous 10 kHz, ≈91% of the events are attenuated. With DNA experiments, the pores are operational for hours (typically >7 h) while the average pore growth is merely ≈0.16 ± 0.1 nm h−1. The current noise is exceptionally stable with traces typically showing <10 pA h−1 increase in noise. Furthermore, a real‐time method to clean and revive pores clogged with analyte with the added benefit of minimal pore growth during cleaning (< 5% of the original diameter) is showcased. The enormity of the data collected herein presents a significant advancement to solid‐state pore performance and will be useful for future ventures such as machine learning where large amounts of pristine data are a prerequisite.
Frankfurt Airport: Die Stahl‐Glaskonstruktion der Check‐in‐Halle des neuen Terminals 3
Authors: Sorli Stefan , Sieber Friedrich 
Published: April 2023

AbstractIm südlichen Bereich vom Flughafen Frankfurt entsteht mit dem Neubau von Terminal 3 eines der größten Infrastrukturprojekte Europas. Nach seiner Fertigstellung können bis zu 19 Mio. Reisende von drei neuen Flugsteigen an Deutschlands größtem Flughafen an‐ und abreisen, durch den Marktplatz schlendern oder in den zahlreichen Lounges entspannen. Da zum Montagezeitpunkt der Check‐in‐Halle der umliegende Rohbau so weit fortgeschritten war, dass die Zugänglichkeit und somit eine Montage mit Schwerlastkranen nicht mehr möglich war, gab es nur mehr eine Lösung zur Realisierung des Dachtragwerks: Die Dachfläche mit gesamt 26.000 m2 wurde in fünf einzelne Segmente aufgeteilt, auf einer Plattform in 28 m Höhe zusammengebaut und von einer Seite aus nacheinander über die Halle mit einer Länge von 200 m gezogen. Wie bringt man ein 2,5 Fußballfelder großes Dachelement auf bzw. über das Terminalhauptgebäude? Dieser bauliche Anspruch stellte alle Beteiligten vor große Herausforderungen. Die Montagehilfskonstruktion musste auf die bereits errichteten vier Geschosse des Massivbaus abgestimmt werden, sodass diese nicht überlastet und beschädigt würden. Auch durften in den Untergeschossen keine zusätzlichen, störenden Unterstellungen gebaut werden, da hier bereits Ausbauarbeiten vorgesehen waren. Wie berechnet man eine Verschubkonstruktion dieser Dimension, welche Eventualitäten müssen berücksichtigt werden und wie lässt sich eine Dachfläche mit 4500 m2 und 1550 t verschieben bzw. verziehen? Schwerpunkte der Tragwerksplanung und der Montage werden in diesem Beitrag beschrieben.
A structural model of student experiences in a career‐forward chemistry laboratory curriculum
Authors: Payne Corey , Crippen Kent J. 
Published: April 2023

AbstractPersistence is a major issue facing students, particularly those who are both female and from underrepresented ethnic minorities (URM). A closer look at the variables affecting their commitment and capacity for continuing the pursuit of their goal allows us to better design support systems that bolster persistence. This study tests a structural equation model (SEM) for students using a career‐forward laboratory chemistry curriculum based upon the Mediation Model of Research Experience (MMRE) that explains the relationships among self‐efficacy, identity as an engineer, and commitment to an engineering career. Data were collected from 426 undergraduate engineering majors at the end of the semester using a previously constructed survey for three semesters of general chemistry laboratory for engineering majors. The research question was addressed using bivariate correlations and a series of SEMs where multigroup analyses were conducted separately for non‐URM and URM participants. Bivariate correlations show significant positive associations between all four variables for the entire group of students. However, when disaggregated, the only significant association for URM participants (n = 109) was between identity as an engineer and commitment to an engineering career. Notably, teamwork self‐efficacy was a negative predictor of commitment to an engineering career for URM participants. Beta‐coefficients from the SEM show that identity and engineering self‐efficacy are the variables most predictive of commitment, with identity being nearly twice as predictive for URM students. This study adds support for professional identity as a key predictive variable for career commitment for URM participants and indicates that a laboratory curriculum that emphasizes applied professional practice can support persistence. Considering the degree to which teamwork is emphasized generally, additional studies are needed to better understand the implications for URM students. Particularly in applications that emphasize long‐term outcomes.

AbstractThis report describes the anaesthetic management of three Maine Coon cats undergoing hybrid cutting balloon dilatation for treatment of cor triatriatum sinister. In cat 1, cor triatriatum sinister was an incidental finding during routine transthoracic echocardiographic screening. Cats 2 and 3 presented with tachypnoea and underwent preoperative therapy with diuretics and antithrombotics. All cats were premedicated with fentanyl. Anaesthesia was co‐induced with midazolam and either etomidate (cats 1 and 2) or alfaxalone (cat 3). Sevoflurane, a fentanyl continuous‐rate infusion and a dexmedetomidine continuous‐rate infusion were used for maintenance of anaesthesia. Intravenous methadone, epidural morphine and methadone, an intercostal block and a subcutaneous wound splash with local anaesthetics complemented the analgesic protocol. Intraoperative complications included arrhythmias, bleeding, hypotension and hypothermia. Postoperative emergence delirium and haemothorax developed in two and one cat, respectively. All three cats recovered well and were discharged home.
Diagnosing gastric ulcers in bottlenose dolphins (Tursiops sp.) using gastroscopy and cytology
Authors: Buhrmann Corrine A. , Gridley Tess , Oellermann Lawrence K. 
Published: April 2023

AbstractGastric ulcers have been reported in a range of cetacean species. Bottlenose dolphins (Tursiops spp.), the most common cetacean species held in captivity, are known to experience gastric ulcers in both wild and captive environments. Documented causes of gastric ulceration include bacterial infection by Helicobacter sp., parasitic infections, high dietary histamine and foreign body ingestion. Gastric ulceration without any obvious cause might be related to stress. Currently, the most accurate way to determine the presence of gastric ulcers in captive dolphins is through direct examination of the stomach mucosa using endoscopy (gastroscopy); a procedure that requires substantial animal training and specialised medical equipment. In this study, we investigate whether cytology of the gastric fluid, collected through the less intensive method of intubation, can be used as an alternative to gastroscopy to predict the presence and severity of gastric ulcers in eight captive bottlenose dolphins at uShaka Sea World, South Africa. An ulcer grading scale was developed to quantify the severity of the dolphins' gastric ulcers observed using gastroscopy. Gastric ulcer severity was then compared with the cytological data collected from gastric fluid samples taken during the gastroscopic examinations. The cytological findings were consistent with other studies, but ulcer severity was not found to be linked to the cytological parameters measured. From these results we suggest that routine cytology of the gastric fluid is not a viable alternative to gastroscopy for diagnosing gastric ulcers in bottlenose dolphins.

ZusammenfassungIn Kap. 5 werden die Ergebnisse einer repräsentativ quotierten Bevölkerungsumfrage zu den Risiken und Nutzenpotenzialen von Big Data in der Mobilität vorgestellt. Es zeigt sich, dass trotz nach wie vor vorherrschender Skepsis eine gewisse „Öffnung“ gegenüber Big Data und der Vernetzung von Daten zu beobachten ist. Insbesondere wenn es um konkrete Nutzenerwartungen und Einsatzfelder geht, äußern die Verkehrsteilnehmer hohes Interesse. Das gilt gleichermaßen für Anwendungen im Individual- als auch im öffentlichen Verkehr. Deutlich geringer ist die Bereitschaft, auch die eigenen Daten bereitzustellen. Hier wird eine gewisse Trittbrettfahrermentalität deutlich, sowie die nach wie vor hohe persönliche Relevanz des Themas Datenschutz, Sorgen vor möglicher Datenfehlnutzung sowie fehlendes Vertrauen in die Akteure der vernetzen Mobilität. Da zeigt sich eine abschließende Abwägung gesellschaftlicher Ziele: Die Vorteile der Vernetzung – Sicherheit, Komfort, Mobilität und Klimaschutz – müssen in Einklang gebracht werden mit Freiheitsrechten und hohen Erwartungen der Bürger an Datenschutz und Privatsphäre.

AbstractTo assess the role of age (early onset psychosis-EOP < 18 years vs. adult onset psychosis-AOP) and diagnosis (schizophrenia spectrum disorders-SSD vs. bipolar disorders-BD) on the duration of untreated psychosis (DUP) and prodromal symptoms in a sample of patients with a first episode of psychosis. 331 patients with a first episode of psychosis (7–35 years old) were recruited and 174 (52.6%) diagnosed with SSD or BD at one-year follow-up through a multicenter longitudinal study. The Symptom Onset in Schizophrenia (SOS) inventory, the Positive and Negative Syndrome Scale and the structured clinical interviews for DSM-IV diagnoses were administered. Generalized linear models compared the main effects and group interaction. 273 AOP (25.2 ± 5.1 years; 66.5% male) and 58 EOP patients (15.5 ± 1.8 years; 70.7% male) were included. EOP patients had significantly more prodromal symptoms with a higher frequency of trouble with thinking, avolition and hallucinations than AOP patients, and significantly different median DUP (91 [33–177] vs. 58 [21–140] days; Z = − 2.006, p = 0.045). This was also significantly longer in SSD vs. BD patients (90 [31–155] vs. 30 [7–66] days; Z = − 2.916, p = 0.004) who, moreover had different profiles of prodromal symptoms. When assessing the interaction between age at onset (EOP/AOP) and type of diagnosis (SSD/BD), avolition was significantly higher (Wald statistic = 3.945; p = 0.047), in AOP patients with SSD compared to AOP BD patients (p = 0.004). Awareness of differences in length of DUP and prodromal symptoms in EOP vs. AOP and SSD vs. BD patients could help improve the early detection of psychosis among minors.
Low-cost modular devices for on-road vehicle detection and characterisation

Published: April 2023

AbstractDetecting and characterising vehicles is one of the purposes of embedded systems used in intelligent environments. An analysis of a vehicle’s characteristics can reveal inappropriate or dangerous behaviour. This detection makes it possible to sanction or notify emergency services to take early and practical actions. Vehicle detection and characterisation systems employ complex sensors such as video cameras, especially in urban environments. These sensors provide high precision and performance, although the price and computational requirements are proportional to their accuracy. These sensors offer high accuracy, but the price and computational requirements are directly proportional to their performance. This article introduces a system based on modular devices that is economical and has a low computational cost. These devices use ultrasonic sensors to detect the speed and length of vehicles. The measurement accuracy is improved through the collaboration of the device modules. The experiments were performed using multiple modules oriented to different angles. This module is coupled with another specifically designed to detect distance using previous modules’ speed and length data. The collaboration between different modules reduces the speed relative error ranges from 1 to 5%, depending on the angle configuration used in the modules.
