International teleconferences in EGAP courses: preparing students for prospective professional situations
Authors: Scott-Monkhouse Anila R. , Tal Michal , Yelenevskaya Maria 
Published: June 2021

Abstract
This paper describes a joint programme developed in 2018 by the University of Parma Language Centre (Italy) and the Humanities and Arts Department of the Technion-Israel Institute of Technology. The aim of the project was to involve students of English for General Academic Purposes in delivering presentations to an unfamiliar foreign audience on a topic relevant to their academic interests. The students were required to prepare for the presentation by exploring and personalising the chosen topic so as to be able to explain it to a group which they had had no previous contact with or information about. Through the active involvement of the students in a realistic implementation of their prospective professional use of English, language learning became a holistic experience where a traditional approach to language learning focusing mainly on vocabulary and macro-skills was integrated with a pragmatic approach which addressed the so-called ‘21st-century skills’ (specifically critical thinking, communication, collaboration and digital literacy). The simulation of situations that they are likely to encounter in their professional lives helped students build their confidence, with the whole learning experience carrying both emotional and social implications. This paper offers an insight into the challenges and issues which arose, and ideas for improving the learning experience. We describe the preparation carried out by the teachers at both universities, and the guided and autonomous work carried out by students in the different stages. A post-conference survey triggered the students’ self-reflection in relation to learning and personal development. The survey was also valuable for the teachers regarding reassessment of teaching strategies and preparation for future joint projects.
Using electrostatic potential maps as visual representations to promote better understanding of chemical bonding

Published: June 2021

Abstract
Static visual representations (VRs) of chemical structures are necessary for an understanding of chemical bonding, a topic which continues to lead to learning difficulties and misconceptions for many students. The efficacy and problems associated with the use of VRs of chemical structures and chemical bonding in the form of electrostatic potential maps resulting from accurate quantum mechanical calculations are the subject of this study, which involved a sample of first year, second semester students, studying the elective course “Science Education” (N = 31). Students distinguished between nonpolar and polar covalent bonding, however, they encountered difficulties with concepts related to ionic bonding. Most students did not employ multistructural thinking (in the sense of the SOLO taxonomy), when providing explanations about the variation of bond polarity. Persistence of a covalent-ionic bond dichotomy was apparent, while for some, ions can be involved in both ionic and covalent bonding. Many students preferred to use their established high school knowledge. On a positive note, many students were clearly affected by the information provided by the colored VRs. Finally, the minimal experience of our students with these VRs leads us to believe that a more systematic and extensive coverage would be likely to produce improved outcomes.

Abstract
With chili and liquid beef tallow as the main raw materials, the processing conditions of chili flavor beef tallow were explored. Gas chromatograpy-ion mobility spectrometry (GC-IMS) was used to determine the volatile compounds in chili flavor beef tallow. The capsaicin and dihydrocapsaicin in chili flavor beef tallow were determined by high performance liquid chromatography (HPLC). The optimum technological conditions were determined, and the index of chromatic aberration, cholesterol was also determined. Based on GC-IMS analysis, 102 kinds of volatile compounds were detected, and the sample III (the ratio of solid–liquid was 1:5, the frying temperature was 120 °C, and the frying time was 15 min) performed better than other samples. The preparation of chili beef tallow improves its antioxidant activity and makes its aroma more intense and more in line with the taste of Chinese people, which provides a theoretical and practical basis for the development of spice beef tallow in the future.
Microcontroller-based simulation of a nonlinear resistive-capacitive-inductance shunted Josephson junction model and applications in electromechanical engineering

Published: June 2021

Abstract
The equations, modelling a nonlinear resistive-capacitive-inductance shunted Josephson junction (NRCLJJ) subjected to various signal shapes of the electrical current, are simulated experimentally using the Arduino Uno-type microcontroller that takes benefit of its simplicity, lost cost, high precision, ease of implementation, and stability compared to the voltage-controlled oscillators (VCO) circuitry. Real time electrical signals are observed presenting various dynamics. Shapiro steps (SS) from the IV-characteristics are also obtained. These real electrical signals are then used to power an electromechanical pendulum in the second part of this work. Bifurcation diagram shows that the pendulum exhibits periodic and chaotic dynamics.

Published: June 2021

Abstract

Objectives
In the current Severe Acute Respiratory Distress Coronavirus 2 (SARS-CoV-2) pandemic there is still great uncertainty about the effects of an infection in pregnancy especially regarding a possible fetal transmission of antibodies to SARS-CoV-2 and the longevity of this immunity.

Methods
Sixteen women who were infected with SARS-CoV-2 during pregnancy and their offspring were included. The antibody response to SARS-CoV-2 was measured in mother and umbilical cord blood peripartum and in a follow-up examination 6–11 weeks after birth. Medical history, symptoms regarding SARS-CoV-2, obstetric and neonatal information were queried following recommendations by the WHO.

Results
A total of 73% of the women and one third of the infants developed antibodies to SARS-CoV-2 spike (S) protein receptor binding domain (RBD), with a long interval between infection and birth proving favorable for a transplacentar transfer of antibodies to the neonates. All infants showed declining or vanishing antibody-titers in the follow-up examination, while the titers of their mothers were stable or even increased.

Conclusions
Our results demonstrate that transplacental transfer of SARS-CoV-2-specific antibodies is possible, but also indicate that the immunity that may be gained as a result might decrease in newborns postpartum. This provides important evidence that could be useful for further studies covering vaccination during pregnancy.
The Courts and Corporate Executive Compensation in Canada
Authors: McGinty Sean 
Published: June 2021

Abstract
Corporate executive compensation in Canada, as in many developed economies, has risen significantly since the 1980s relative to that of the average worker. This has posed an issue for corporate governance due to concerns that the trend may not be serving the corporation and its stakeholders well, and also an issue for society as a whole due to its impact on income inequality more generally. This has raised interest in the role played by institutions in shaping executive pay decisions and also in what role they might play in resolving these issues. This paper looks at the role played by one such institution, the courts, with two ends in mind. The first is to gain an empirical understanding of what the courts actually do with respect to executive pay disputes. It does so by examining a set of decisions by Canadian courts between 1876 and 2018 collected by the author in which the claim of a corporate executive to their pay was at issue in order to get a better picture of how the courts are accessed, who relies on them, what rules they use, how the courts respond and how trends in these have evolved over time. It finds that the litigation of executive pay disputes has varied widely over time with a variety of stakeholders using a variety of legal areas – corporate law, contract law and bankruptcy/arrangement law in particular – to dispute the entitlement of executives to their pay. In recent years however litigation has come to be dominated by oppression remedy applications, with plaintiffs being successful in challenging pay in a majority of decisions. This paints a significantly different picture of the role of the courts than that developed in the American literature which focuses almost exclusively on shareholder use of derivative actions to monitor pay decisions. The second is to examine how better use might be made of the courts in order to remedy the broader problems for corporate stakeholders and society as a whole that corporate executive pay practice presents. It suggests that an expanded role for the oppression remedy by corporate employees should be considered as a policy option which would better reflect a stakeholder model of governance and address broader inequality concerns at the same time.

Published: June 2021

Abstract
Nonlinear biochemical systems such as the anaerobic digestion process experience the problem of the multi-stability phenomena, and thus, the dynamic spectrum of the system has several undesired equilibrium states. As a result, the selection of initial conditions and operating parameters to avoid such states is of importance. In this work, we present a data-driven approach, which relies on the generation of several system trajectories of the anaerobic digestion system and the construction of a data-driven Koopman operator to give a concise criterion for the classification of arbitrary initial conditions in the state space. Unlike other approximation methods, the criterion does not rely on difficult geometrical analysis of the identified boundaries to produce the classification.
Extraction of optical solitons in birefringent fibers for Biswas-Arshed equation via extended trial equation method
Authors: Tahir Muhammad , Awan Aziz Ullah , Abro Kashif Ali 
Published: June 2021

Abstract
This article obtains optical solitons to the Biswas-Arshed equation for birefringent fibers with higher order dispersions and in the absence of four-wave mixing terms, in a media with Kerr type nonlinearity. Optical dark, singular and bright soliton solutions are articulated by applying an imaginative integration technique, the extended trial equation scheme. Various additional traveling wave solutions are produced with this integration technique, which include rational solutions, Jacobi elliptic function solutions and periodic singular solutions. From the mathematical analysis some constraints are recognized that ensure the actuality of solitons.

Published: June 2021

Abstract
Cellulose based nanomaterials have the great potential to be applied to paper as bulk additive or coating material to improve overall final properties, especially in secondary fiber. In the present work, the effect of applying different kinds of cellulose nanofibrils (CNF) to papers obtained from recycled fibers using size press on physical, mechanical and barrier properties was investigated and compared with the sole use of starch as coating material. The coating process of CNF was carried out by the addition of size press grade starch to coating suspension. As a cellulose source, wheat straw was evaluated and CNF was obtained through oxidative and enzymatic pretreatments. Results indicate that starch/CNF suspension improves the overall paper properties. As a result of the deposition of coating suspension contains of 4 % wt. periodate-oxidized CNF onto paper surface, tensile and burst indices of papersheets increased as 52.2 % and 194.4 %. Significant decreases were observed in air permeability as 69.8 %. Compression tests also have been conducted to evaluate papersheets end-use properties. In comparison to the other pretreated CNF, due to is lower viscosity, applying periodate-oxidized CNF as size press significantly increased the mechanical properties of the papers fabricated from the recycled pulps.
Solvent regulation synthesis of single-component white emission carbon quantum dots for white light-emitting diodes

Published: June 2021

Abstract
White light-emitting diodes (WLEDs) hold great promise in lighting, display, and visible light communication devices, and single-component white emission carbon quantum dots (SCWE-CQDs) as the key component of WLEDs have many outstanding advantages. However, rapid and efficient synthesis of SCWE-CQDs with high photoluminescence quantum yield (PLQY) and stability remains challenging. Here, we report a novel solvent engineering strategy to obtain highly photoluminescent SCWE-CQDs by controlling the dilution ratios between N,N-dimethylformamide (DMF) and pristine red carbon quantum dots (RCQDs) solution. By optimizing synthesis conditions, the relative PLQY of the SCWE-CQDs solution reached 53%. Morphological, structural, and optical property characterizations indicate that the combined action of the hydrogen bond (HB) effect and the size effect leads to the blue shift of RCQDs, but the HB effect is more dominant than the particle size in causing large spectral shifts. In addition, the WLEDs with high color rendering index of 89 and remarkable reliability were obtained based on the highly photoluminescent SCWE-CQDs. This facile solvent engineering approach for synthesizing tunable emission CQDs will promote the progress of carbon-based luminescent materials for applications in optoelectronic devices.
Wahrheitsnähe, Wahrheitsferne – Überlegungen zum Verhältnis von Religionen und Wahrheit
Authors: Pausch Eberhard Martin 
Published: June 2021

Zusammenfassung
Die Hauptthese dieses Artikels ist inspiriert von Lessings Werk „Nathan der Weise“: Die monotheistischen Religionen – was auch immer sie sonst sein mögen – sind soziale Systeme. Als solche können sie weder wahr noch falsch sein. Dennoch beinhalten sie Propositionen und Wirklichkeitsverständnisse, die für sich Wahrheit beanspruchen. Deren Verifikation ist aber unter irdischen Bedingungen nicht möglich. Als Menschen können wir nur nach Wahrheit suchen und darauf hoffen, dass Gott uns in die Wahrheit führt. Daher muss das Verhältnis von Religion und Wahrheit in Modellen der Partizipation und der Approximation gedacht werden. Abzulehnen sind hingegen Modelle wie Dogmatismus, Skeptizismus, Pluralismus, Indifferentismus und Egalismus.

Published: June 2021

Abstract
The objective of this study was to investigate the adhesion performance of eight fast-growing wood species, namely, Enterolobium cyclocarpum, Paraserianthes falcataria, Shorea sp., Toona sinensis, Gmelina arborea, Pinus merkusii, Acacia mangium, and Acacia hybrid obtained from the tropical region. The wettability test was conducted by contact angle measurement, while the adhesion performance was expressed by strength retention (SR) and wood failure (WF) percentages through block shear tested under the Japanese Agricultural Standard (JAS). Results showed that smaller contact angle for P. falcataria followed by E. cyclocarpum, P. merkusii, T. sinensis, and Shorea indicated that the surfaces were easier to be glued than that of G. arborea, A. mangium, and A. hybrid. It is indicated that high wettability of P. falcataria, E. cyclocarpum, P. merkusii, T. sinensis, and Shorea resulted in the better adhesive spread and more intimate contact between the wood surface and the adhesive as shown by their high SR with high WF percentages.

Persistent pain relief following a single injection of a local anesthetic for neuropathic abdominal wall and groin pain
Authors: Jacobs Monica L. Y. E. , Scheltinga Marc R. M. , Roumen Rudi M. H. 
Published: June 2021

Abstract

Objectives
It is our experience that a small portion of patients with neuropathic abdominal wall pain syndromes such as the anterior cutaneous nerve entrapment syndrome (ACNES) have a long term beneficial response following just one single tender point injection (TPI) with a local anesthetic agent. This report focuses on the phenomenon of ongoing pain relief following a single local anesthetic injection in neuropathic abdominal wall and groin pain syndromes.

Methods
This report is an overview based on earlier studies from a center of expertise for neuropathic abdominal wall and groin pain syndromes. All studies on neuropathic abdominal wall and groin pain syndromes reporting on efficacy of a diagnostic TPI using a local anesthetic agent were included.

Results
A total of 10 studies including 834 patients fulfilled study criteria. Each of these 10 studies found that approximately 10% (range, 4–25%) of the cases experienced persistent pain relief after a single TPI with lidocaine 1%.

Conclusions
Persistent pain relief after a single TPI using a local anesthetic agent may be observed in approximately one of 10 patients suffering from neuropathic abdominal wall or groin pain syndromes. When a patient is suspected of having a neuropathic abdominal wall or groin pain syndrome, a single TPI using a local anesthetic agent should be administered as long term pain relief may occasionally occur.

Abstract
X-ray crystallography on [EtOC(=O)N(H)C(=N+H2)NH2]Cl·½H2O (1) shows the asymmetric unit to comprise two independent cations, two chloride anions and crystal water. The main conformational difference between the cations is seen in the relative orientation of the ethyl groups; geometry-optimisation confirms the all-trans conformation is the most stable. The remaining parts of the cations are co-planar and feature intramolecular N–H···O(carbonyl) hydrogen bonds. An analysis of the C–N bonds suggests substantial delocalisation of the positive charge over the CN3 atoms. In the crystal, columns comprising the first independent cation are surrounded by four columns of the second cation within a network of water-O–H···Cl, N–H···Cl and N–H···O(water, carbonyl) hydrogen bonds, many of which are charge-assisted. The packing has been further investigated by Hirshfeld surface analysis, molecular electrostatic potential and interaction energy calculations. The charge-assisted N–H···Cl hydrogen bonds are significantly stronger than the water-O–H···Cl interactions consistent the distribution of the positive charge over the CN3 atoms.

Abstract
Andrade, MS, Silva, WA, de Lira, CAB, Mascarin, NC, Vancini, RL, Nikolaidis, PT, and Knechtle, B. Isokinetic muscular strength and aerobic physical fitness in recreational long-distance runners: A cross-sectional study. J Strength Cond Res 36(3): e73–e80, 2022—Muscular strength, bilateral asymmetry, and imbalance between antagonist muscles have been considered as risk factors for knee injuries. Moreover, muscular strength has also been associated with aerobic performance. The aim of the study was to investigate bilateral muscular symmetry and muscular strength balance assessed by isokinetic dynamometry in recreational long-distance runners and to verify whether knee muscular strength would be associated with maximal oxygen uptake (V̇o
2max), anaerobic threshold (AT), and running economy (RE). Thirty-nine runners (male [n = 24]: age, 30 ± 8 years; height, 176.0 ± 7.3 cm; body mass, 70.3 ± 8.0 kg; race pace below 4:30 min·km−1 and female [n = 15]: age, 31 ± 7 years; height, 163.0 ± 3.8 cm; body mass, 55.9 ± 4.7 kg; race pace below 5:00 min·km−1) participated in this study. Comparing the conventional knee balance ratio with the literature recommendation (60%), male runners presented significantly lower values for the nondominant side (55.5 ± 7.3%; p = 0.001; d = 0.85; confidence interval [CI] = 0.47 to 1.20) but not for the dominant side (58.1 ± 6.8%; p = 0.208; d = 0.37; CI = −0.12 to 0.86). Female runners presented lower values for both sides (52.1 ± 7.1%; p = 0.001; d = 1.55; CI = 0.86 to 2.20 and 50.7 ± 8.0%; p = 0.001; d = 1.62; CI = 0.90 to 2.30 for dominant and nondominant sides, respectively). Female and male runners presented nonfunctional ratio imbalance and asymmetry of bilateral strength. Strength outcomes were not associated with V̇o
2max, AT, or RE. In conclusion, recreational runners were characterized by an imbalance in muscular strength between knee flexor and extensor muscles, which was more obvious in female runners, and by symmetrical thigh muscle strength values. Moreover, muscular isokinetic knee flexor and extensor muscle strength was not associated with aerobic fitness parameters.
