Authors: Zhang Zhe , Song Xiaoling , Gong Xue , Yin Yong , Lev Benjamin , Zhou Xiaoyang 
Published: September 2022

AbstractMotivated by a practical production scheduling problem at a factory, this article studies scheduling problems in seru production system (SPS). Seru is a relatively new‐type production mode originating in Japan and has brought inspiring benefits to production practice. Following the just‐in‐time philosophy of SPS, the objective of seru scheduling problem is to minimize the sum of earliness and tardiness penalties. Two common due date types of job are considered, and the seru scheduling problem is formulated as a 0–1 quadratic programming model with linear constraints that is then reformulated using convex reformulation methods to ensure convexity. Computational experiments are implemented. Experimental results indicate that the proposed exact solution method can obtain approximate optimal solutions efficiently and effectively for seru scheduling problems.

Published: September 2022

AbstractObjectiveThis trial evaluated a smartphone application's effectiveness in improving adherence to vitamin and mineral supplementation postoperatively.MethodsThis study was a randomized controlled trial comprising 140 patients undergoing bariatric surgery (gastric bypass or sleeve gastrectomy). Participants were randomized 1:1 to the 12‐week intervention, using the smartphone application PromMera, or to standard care. The primary end point was adherence to vitamin and mineral supplementation.ResultsInitiation rate and overall adherence to supplementation were high in both groups. Change in objectively measured adherence rate from before the intervention to 1 year post surgery, measured with pharmacy refill data, did not differ between groups for vitamin B12 (−9.6% [SD = 27%] vs. −9.3% [SD = 30%]; p = 0.48) or calcium/vitamin D (−12.3% [SD = 29%] vs. −11.5% [SD = 32%]; p = 0.44). A modest effect on the secondary end point (subjectively measured adherence, using the Medication Adherence Report Scale‐5) was seen immediately after the intervention (intervention group 0.00 [SD = 1.3] vs. control group −1.2 [SD = 3.5]; p = 0.021), but this effect did not persist 1 year post surgery. No differences were detected in the prevalence of biochemical deficiencies.ConclusionsThe use of the smartphone application PromMera did not obtain a lasting improvement in adherence to vitamin and mineral supplementation 1 year post bariatric surgery.

Published: September 2022

AbstractIn this review, the EMI shielding properties of the various carbonaceous fillers are thoroughly reviewed. Electromagnetic interference (EMI) had been a cause of major concern in the live broadcasting, entertainment, aviation and defense industries since vital radio signals could create more interference, which could lead to poor performance. To reduce the effect of EMI, the organic polymeric composites along with the carbonaceous fillers are mostly used since they are flexible, low denser, high mechanical strength, high thermo‐stability, high electrical and thermal conductivity, excellent fracture toughness, and high friction/wear resistance. There are lot of carbon based materials are being used as EMI shielding material in mono and compound form. This review gives a broad understanding of the utilization of carbonaceous fillers in polymer matrixes. Thus, the overall coverage on this carbon based materials and their effectiveness could help the researchers to find right carbon material for suitable application. According to this review, the absorption mechanism is vital to achieve high EMI shielding effect. The fillers such as graphene and CNTs are most preferable EMI shielding filler, according to the vast coverage of previous articles. However, there are more magnetoelectric materials also evolved recently, having combined properties of both conductive and magnetic, yielding high SE at elevated frequencies.

Published: September 2022

AbstractIn the current study, naturally occurring halloysite nanotube (HNT) is first modified by vinyltriethoxysilane to obtain vinyl‐functionalized HNT (HNT‐Vinyl). Subsequently, the HNT‐Vinyl is added as nanofiller by varying weight from 0 to 8% in the presence of multifunctional methacrylates (bisphenol A‐dimethacrylate and triethylene glycol dimethacrylate). Free radical photocrosslinking polymerization of these materials provides the in‐situ formation of HNT/thermoset nanocomposites. Comparison of characteristic bands of the nanocomposite components by Fourier transform infrared spectroscopy confirms the presence and covalent bonding of HNT nanofiller in the thermoset matrix. Thermal properties of obtained HNT/thermoset nanocomposites have been compared with neat thermoset as a reference sample using thermogravimetric analysis. Moreover, the existence and dispersion of nanofillers in the nanocomposites have been proved by scanning electron microscopy and transmission electron microscopy. The HNT nanofiller has been detected as agglomerated/non‐agglomerated morphology in the thermoset matrix. On the other hand, the addition of HNT‐Vinyl to the thermoset matrix has improved the mechanical properties of nanocomposites. Especially, a dramatic increase on tensile strength values has been determined with 4% HNT‐Vinyl loading. Tensile strength and elastic modulus values of the corresponding nanocomposite are 4.9 and 1.5 times higher than those of the neat thermoset.
A case report of nonsurgical idiopathic normal pressure hydrocephalus differentiated from Alzheimer's dementia: Levetiracetam was effective in symptomatic epilepsy
Authors: Ishida Tetsuro , Murayama Tomonori , Kobayashi Seiju 
Published: September 2022

AbstractBackgroundIdiopathic normal pressure hydrocephalus (iNPH) is a common form of dementia that causes gait disturbance, cognitive impairment, and urinary incontinence. iNPH is a “treatable dementia” that can be treated with shunt surgery, but this can be ineffective in some cases and can be accompanied by complications. As a result, many patients with iNPH do not undergo surgery. However, there is insufficient evidence on effective treatments other than surgical therapy.Case PresentationA 75‐year‐old woman presented to our hospital with a chief complaint of cognitive decline. She showed reduced motivation and inactivity. Brain magnetic resonance imaging showed a high score on the Evans Index (maximum width between bilateral lateral ventricular anterior horns/maximum intracranial cavity in the same slice). The subarachnoid space was enlarged at and below the Sylvian fissure, and narrowed at the higher arcuate region. She was diagnosed with iNPH. However, no shunt surgery was performed; 11 months later, she had a generalized convulsive seizure with loss of consciousness. An electroencephalogram showed generalized epileptic discharges. The possibility of surgery for her iNPH was ruled out. Levetiracetam prevented seizure recurrence and cognitive functions such as spontaneity and motivation were improved.ConclusionIt is often assumed that surgery is the only effective treatment for patients with iNPH. However, as in the present case, symptomatic epileptic seizures may be a factor in dementia. Even in the absence of surgical treatment, we should examine the cause of dementia in patients with iNPH and consider pharmacological treatment, including antiepileptic drugs.
In Situ Measurement of the Fragmentation Behavior of Al/PTFE Reactive Materials Subjected to Explosive Loading, Part 2: Fragment Velocity and Trajectory Measurements
Authors: Palmer Sean , Youngblood Stewart , Kimberley Jamie , Hargather Michael J. 
Published: September 2022

AbstractHigh‐speed optical diagnostics and image analysis methods are applied to implement an automated Kalman filter based tracking technique to measure fragment size, velocity, and trajectories for studying the fragmentation behavior of explosively launched Al/PTFE cylinders. Bivariate histograms of equivalent spherical diameters of fragments greater than 1 mm and their corresponding velocities are presented to describe the explosively‐driven fragmentation behavior of several Al/PTFE specimens. Spatial cross‐correlation of fragments is also implemented to optically determine, from high‐fidelity high‐speed images, the spatial distribution of fragment trajectories inside the diagnostic section. Sizes determined from the Kalman filter based tracking process are compared with the sizes determined from the high‐fidelity measurements in Part 1. Similarly, the velocities of discretely tracked fragments are compared to velocity estimates from the bulk fragment displacement calculated using a phase correlation routine.

Published: September 2022

AbstractBackgroundTraditional abamectin (Abm) formulations have several shortcomings, such as low water solubility, burst release behavior, poor photostability, and short persistence periods, which decrease their pesticidal activity and the risks they pose to the environment. Nanomaterial‐based pesticide delivery systems (PDSs) provide new strategies for the efficient and safe application of pesticides. Here, we developed Abm‐loaded graphene oxide (Abm/GO) as a PDS for the sustained release of Abm, which shows enhanced control efficacy against Plutella xylostella.ResultsThe hydrophobic Abm molecule was effectively loaded on GO nanocarrier by a physisorption method, which formed a uniform and stable Abm/GO nanoformulation. GO possesses high adsorption capacity and can effectively load Abm. The Abm/GO nanoformulation shows enhanced water dispersion stability and can remain stable during a 2‐year storage period in contrast to the water‐insoluble Abm. In addition, the Abm/GO nanoformulation exhibits sustained pesticide release behavior and possesses significantly improved anti‐ultraviolet properties. Thus, the Abm/GO nanoformulation shows superior pesticidal activity compared with Abm. Abm/GO showed negligible toxicity to maize seedlings, and its GO nanocarrier can reduce the cytotoxicity of Abm to A549 cells.ConclusionGO‐based PDSs can effectively overcome the disadvantages of traditional pesticides, such as their insolubility, burst release behavior, instability, and short persistence period. GO shows much future promise in agriculture in light of its industrialization potential. © 2022 The Authors.

Published: September 2022

AbstractDuring last two decades, researchers have employed organochalcogen compounds as ligands for the development of pre‐formed chalcogen ligated molecular complexes. During 2013–2020, various chalcogen containing homogenous catalytic systems for Suzuki Miyaura cross‐coupling reaction have been synthesized. The review provides insights into the synthetic methodologies for the preparation of organochalcogen ligands and their transition metal complexes. Another central aspect discussed is the application of such catalytic systems in Suzuki Miyaura coupling. Rationalization about the effect of temperature, substrate scope, organoborane derivatives and aryl halides employed has been elaborated. Effect of binding mode, ligand framework, chalcogen donor atom, metal and many other aspects that influence the catalytic potential of various systems have also been covered. Various other aspects such as green catalysis, use of non‐conventional energy sources have also been analyzed.

Published: September 2022

AbstractSulfonate esters are important owing to their special bioactivities. Nevertheless, severe reaction conditions, use of expensive catalysts along with additives and the numerous side reactions in the previously reported methods demand the development of valid approaches for the synthesis of aryl sulfonate esters. Herein, we report a facile synthetic strategy utilizing the VIVbased catalyst for the carbene insertion into the O−H bond of sulfonic acids to afford sulfonate esters up to 90 % yield under mild reaction conditions. All the synthesized sulfonate esters were fully characterized by using standard spectroscopic and analytical techniques such as NMR, IR, ESI‐MS and single crystal XRD analysis.

AbstractDevelopment of cost‐effective efficient bifunctional electrocatalysts is indispensable for commercialization of metal‐air batteries. Here, vacancy‐induced nanostructured LaMnO3 perovskite was generated by a facile hydrothermal method and explored as a bifunctional air‐breathing electrode for rechargeable Lithium‐Air battery. Materials characterizations confirmed the formation of the nanostructured LaMnO3 with anion and cation vacancies. The LaMnO3 electrocatalyst on rotating ring disc electrode study showed excellent oxygen reduction reaction and oxygen evolution reaction activities in 0.1 M KOH electrolyte. The oxygen vacancies associated with the LaMnO3 acted as catalyst centre and promoted reaction rate for the ORR and OER. Laboratory prototype CR‐2032 air‐coin cell was fabricated using the LaMnO3 as air‐breathing electrode, resulted open circuit voltage 3.3 V for more than 5 days and high discharge capacity of 3100 mA h g−1 at current density of 50 mA g−1. Further, once charged air‐coin cell could power an LED for more than 24 h continuously.

AbstractIn this research, some new heterocyclic hydrazone compounds bearing an aryl sulfonate moiety (2 a–i) were facilely synthesized for the first time and elucidated by some spectroscopic techniques (FT‐IR, 1H‐ and 13C NMR). The inhibitory potentials of all synthesized molecules on acetylcholinesterase (AChE), butyrylcholinesterase (BChE), tyrosinase enzymes were investigated. Also, DPPH, ABTS and CUPRAC antioxidant activities of all molecules were examined. In BChE assay, it was determined that 2‐Formylphenyl 4‐chlorobenzenesulfonate (1 a) (IC50=10.45 μM), 5‐(diethylamino)‐2‐formylphenyl 4‐Chlorobenzenesulfonate (1 h) (IC50=10.12 μM), and 1‐((2‐Nicotinoylhydrazono)methyl)naphthalen‐2‐yl 4‐chlorobenzenesulfonate (2 i) (IC50=9.89 μM) were found to be more effective than the standard compound galanthamine and donepezil. In DPPH assay, 2‐((2‐Nicotinoylhydrazono)methyl)phenyl 4‐chlorobenzenesulfonate (2 a) (IC50=361.03 μM) and 5‐Methoxy‐2‐((2‐nicotinoylhydrazono)methyl)phenyl 4‐chlorobenzenesulfonate (2 e) (IC50=348.9 μM) indicated the highest antioxidant activities. On the other hand, the molecular electrostatic potential (MEP) maps of compounds 1 a, 1 h, 2 i and galanthamine molecules were investigated. The molecular docking study for BChE enzyme structure was found to be compatible with the experimental results and MEP maps.

Published: September 2022

AbstractThe reaction of complexes [Pt(μ‐Cl)(arylolefin)]2 with various either weak σ‐donor LN,S,O ligands or strong σ‐donor NHCs ligands results in [PtCl(arylolefin)(LN,S,O)] with LN,S,O in a cis position to the C=C group (series A) or [PtCl(arylolefin)(NHC)] with NHC in a trans position to the C=C group (series B), respectively. The reaction directions are decided by the nature of the reactants, and not by the reaction conditions. Analyses of NMR spectra, XRD and DFT results indicate that the formation of series B is strongly dominated by electronic properties, while steric factors direct the reaction to form series A. The chemical shifts of ethylenic protons and carbons as well as the values of 2JPtH, 3JPtH for the allyl protons and the 3JPtH value for H6 in the aryl group are unambiguously different for series A and series B. In addition, one complex [Pt(μ‐Cl)(EtEug)]2 and five complexes [PtCl(arylolefin)(NHC)] have been characterized by single crystal XRD.
Toward assessment for playful learning in early childhood: Influences on teachers' science assessment practices
Authors: Guarrella Cristina , van Driel Jan , Cohrssen Caroline 
Published: September 2022

AbstractIn many countries, play is the vehicle for teaching and learning, requiring early childhood teachers to recognize and assess children's demonstrations of knowledge and capabilities as they are displayed during play. In the context of science learning, assessing what children know already, referred to as “assessment for learning,” equips teachers with the knowledge required to make purposeful decisions during these playful experiences and guide children's science process skill development while following their interests. Consistent evidence since the introduction of national quality standards in Australia has identified a need to strengthen teacher capabilities in assessment. This research investigated teachers' assessment practices, and the influences on these practices, during the implementation of a suite of playful science experiences in long day care and preschool settings in the Northern Territory (NT), Australia. Teachers were introduced to the NT Preschool Science Games and were supported to apply an assessment tool designed for the observation and development of science process skills. Adopting a multiple case study approach, semistructured interviews from three cases were thematically analyzed. Our findings demonstrate that despite having specific tools to support assessment for learning these were inconsistently applied. Thematic analysis of semistructured interviews revealed that assessment practice was influenced by contextual influences, affective responses and teaching practice. Unpacking these themes further, we identified that following children's interests was associated with the absence of systematic assessment of scientific thinking to inform planning for learning within the informal curriculum. To support teacher practice in early childhood science, and promote the assessment of children's capabilities within playful learning, we propose a model of Assessment for playful learning.

Published: September 2022

AbstractAs early as two months into the COVID‐19 pandemic, popular media started reporting that women leaders, compared to men leaders, were managing COVID‐19 better. This paper empirically examines the impact of women leaders in managing pandemic health outcomes one year after the onset of the pandemic. Further, we consider leader effectiveness within the context of country culture. We find that women's leadership is indeed associated with better containment of the pandemic. We also find that certain country‐level cultural traits play a significant role in pandemic outcomes. More hierarchical societies experience higher COVID‐19 cases and death. Individualistic cultures and masculine cultures are associated with more deaths from the pandemic. Some cultural traits modulate women's ability to manage COVID‐19. Our findings have implications for health policy and provide rationale for promoting gender equity in political leadership.
The Effect of Exogenous Shocks on the Administration of Online Voting: Evidence from Ontario, Canada

Published: September 2022

AbstractThis paper examines the impact of two exogenous shocks – a 2018 technical incident that took place in Ontario, Canada, and the COVID-19 pandemic – on the administration of local elections in Ontario. Drawing upon survey and focus group data, this paper concludes that these two exogenous shocks affected the perception and adoption of online voting on the municipal level in differential ways. We find that the COVID-19 pandemic had a greater perceived effect upon the decision to adopt online voting than the 2018 technical incident. However, the perceived effects of the 2018 technical incident were just as likely to be felt in unaffected municipalities as they were in those that had been directly affected. Municipalities that had not used online voting in 2018 and medium-sized cities were more negatively affected by the 2018 technical incident. In contrast, the perceived effects of the COVID-19 pandemic did not hinge upon the previous use of online voting, city size, or the urban/rural divide.

AbstractThe spread of Augmented Reality (AR) and the recent technological developments, provide innovative techniques and tools that show a growing potential in education. One of the pilots of the European Horizon 2020 project ARETE (Augmented Reality Interactive Educational System) aims to investigate and evaluate for the first time the introduction of an AR solution to support a behavioral lesson in schools where the Positive Behaviour Intervention and Support (PBIS) methodology is adopted. Specifically in this paper, we describe the architectural design and implementation of a PBIS-AR application as a component of the ARETE ecosystem. It describes the functionality of the system and the teaching process that the AR solution will support.
