A comparative study between brick and stone aggregate concrete using rice husk ash as partial cement replacement
Authors: Bhowmik R.N. , Pal J. 
Published: September 2022

AbstractToday's world cannot be imagined without the application of concrete. Although as a constituent of concrete stone aggregate is mostly used, there are certain areas on this earth where it is scarcely available which leads to the use of brick aggregate. Moreover, as supplementary cementitious material, use of rice husk ash is beneficial to our environment. So, the study presents the possibility of using the brick aggregate and rice husk ash to the possible extent in making concrete by comparing stone and brick aggregate concrete, with rice husk ash as partial cement replacement. The specimens were prepared using water to binder ratios varying from 0.38 to 0.54. Properties of fresh and hardened concrete were measured using different tests on the specimens.The results of the mechanical tests were also co‐related with the microscopic image studies.This study finds that for a higher grade of concrete optimum rice husk ash replacement varies between 5 % to 10 % and for lower grade of concrete the rice husk ash replacement varies between 10 % to 15 %. The study also shows that using rice husk ash, brick aggregate concrete exhibits better improvement in comparison to stone aggregate concrete.
Mapping research findings on change implementation in nursing practice: A scoping literature review
Authors: Salma Israa , Waelli Mathias 
Published: September 2022

AbstractAimsThe aim of this study was to map the diverse factors impacting change implementation in nursing practices and investigate different implementation strategies.DesignScoping literature review following PRISMA‐ScR extension.MethodsData were collected from PubMed, Ebsco, Scopus and ScienceDirect databases from 1990 onwards. Only English peer‐reviewed studies reporting an implementation of change in nursing practice were included. Of 9,954 studies, 425 abstracts were scanned and 98 full‐text articles were screened. Finally, 28 studies were selected.ResultsA multifaceted approach, with a tailored intervention, was the most effective implementation strategy. Most identified factors were considered systematic, for example resource availability, leadership and knowledge. However, others related to local social and material context were identified in fewer number of studies. These seem to be operational elements for implementation processes. Both types of factors are essential and must be considered for successful implementation.ConclusionWe advocate the development of framework including systematic factors and which capture the local context flexibility.

AbstractCu2+ ions (ZCu2+(OH)−, Z2Cu2+) are regarded as the NH3‐SCR (SCR=selective catalytic reduction) active site precursors of Cu‐exchanged chabazite (CHA) which is among the best available catalysts for the abatement of NOx from Diesel engines. During SCR operation, copper sites undergo reduction (Reduction half‐cycle, RHC: Cu2+→Cu+) and oxidation (Oxidaton half‐cycle, OHC: Cu+→Cu2+) semi cycles, whose associated mechanisms are still debated. We recently proposed CO oxidation to CO2 as an effective method to probe the formation of multinuclear Cu2+ species as the initial low‐T RHC step. NH3 pre‐adsorption determined a net positive effect on the CO2 production: by solvating ZCu2+(OH)− ions, ammonia enhances their mobility, favoring their coupling to form binuclear complexes which can catalyze the reaction. In this work, dry CO oxidation experiments, preceded by modulated NH3 feed phases, clearly showed that CO2 production enhancements are correlated with the extent of Cu2+ ion solvation by NH3. Analogies with the SCR‐RHC phase are evidenced: the NH3‐Cu2+ presence ensures the characteristic dynamics associated with a second order kinetic dependence on the oxidized Cu2+ fraction. These findings provide novel information on the NH3 role in the low‐T SCR redox mechanism and on the nature of the related active catalyst sites.

Published: September 2022

AbstractBackgroundInappropriate humidification of inspired gas during mechanical ventilation can impair lung development in extremely low birthweight (ELBW) infants. Humidification depends on multiple factors, such as the heater‐humidifier device used, type of ventilation, and environmental factors. Few studies have examined inspired gas humidification in these infants, especially during high‐frequency oscillatory ventilation (HFOV). Our objective was to compare humidity during HFOV and intermittent positive pressure ventilation (IPPV), in vitro and in vivo.MethodsIn vitro and in vivo studies used the same ventilator during both HFOV and IPPV. The bench study used a neonatal test lung and two heater‐humidifiers with their specific circuits; the in vivo study prospectively included preterm infants born before 28 weeks of gestation.ResultsOn bench testing, mean absolute (AH) and relative (RH) humidity values were significantly lower during HFOV than IPPV (RH = 79.4 ± 8.1% vs. 89.0 ± 6.2%, p < 0.001). Regardless of the ventilatory mode, mean RH significantly differed between the two heater‐humidifiers (89.6 ± 6.7% vs 78.7 ± 6.8%, p = 0.003). The in vivo study included 10 neonates (mean ± SD gestational age: 25.7 ± 0.9 weeks and birthweight: 624.4 ± 96.1 g). Mean RH during HFOV was significantly lower than during IPPV (74.6 ± 5.7% vs. 83.0 ± 6.7%, p = 0.004).ConclusionRH was significantly lower during HFOV than IPPV, both in vitro and in vivo. The type of heater‐humidifier also influenced humidification. More systematic measurements of humidity of inspired gas, especially during HFOV, should be considered to optimize humidification and consequently lung protection in ELBW infants.

AbstractBackground and PurposeEnsuring access to high quality services in paediatric physiotherapy (PT) is important to respond to the diverse needs of children. The accessibility and quality of paediatric PT services has however never been explored internationally. The purpose of this study is to explore the perceived strengths, weaknesses, opportunities, and threats (SWOT) of paediatric PT services offered around the world.MethodA cross‐sectional survey design method was used with a subsample of physiotherapists (PTs) who had previously participated in an online survey. The survey used for this study included close‐ and open‐ended questions about access to services and the SWOT of PT services within participants' country. Descriptive statistics were used to summarize quantitative data and a content analysis was performed on open‐ended questions.ResultsOverall, 47 PTs from 47 countries completed the survey; 36% of participants reported that free access was available to all children in their country while 34% stated that a referral was always required when accessing services. Lack of direct access, insufficient specialized PT, financial and geographical issues were the main perceived barriers to access services. Access also emerged as one of the nine themes following the SWOT analysis. Other themes included education, quality of PT approaches, PT practices, communication and cooperation, teamwork, government, resources, and attitudes of PTs.DiscussionDespite variations in accessing services and how services are delivered across countries, some similar themes influencing PTs practices were found. Future opportunities for PTs working with children should aim at optimizing the initial training and professional development of PTs in paediatrics, increasing access to services for all children and advocating for sustainable and well‐coordinated models of care building on best practices.

Published: September 2022

AbstractPharmacy services within hospitals are changing, with more taking on medication reconciliation activities. This systematic review was conducted to determine the measured impacts of Pharmacy teams working in an acute or emergency medicine department. The protocol followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was prospectively registered on PROSPERO, National Institute for Health and Care Research, UK registration number: CRD42020187487. The systematic review had two co‐primary aims: a reduction in the number of incorrect prescriptions on admission by comparing the medication list from primary care to secondary care, and a reduction in the severity of harm caused by these incorrect prescriptions; chosen to determine the impact of pharmacy‐led medication reconciliation services in the emergency and acute medicine setting. Seventeen articles were included. Fifteen were non‐randomized controlled trials and two were randomized controlled trials. The number of patients combined for all studies was 7630. No studies included were based within the UK. All studies showed benefits in terms of a reduction in medicine errors and patient harm, compared to control arms. Nine articles were included in a statistical analysis comparing the pharmacy intervention arm with the non‐pharmacy control arm, with a Chi2 of 101.10 and I2 value = 92%. However, studies were heterogenous with different outcome measures and many showed evidence of bias. The included studies consistently indicated that pharmacy services based within acute or emergency medicine departments in hospitals were associated with fewer medication errors. Further studies are needed to understand the health and economic impact of deploying a pharmacy service in acute medical settings including out‐of‐hours working.
Flocking control for Cucker–Smale model under denial‐of‐service attacks

Published: September 2022

AbstractIn this article, the issue of flocking control for Cucker–Smale model under denial‐of‐service (DoS) attacks is discussed. It is assumed that there is an active stage and an asleep stage for each period of the DoS. Malicious attacks partially or completely destroy the network communication links in the active stages, and replenish energy without any attacks in the dormant stages. By constructing the agents' position and velocity errors, the C–S model under DoS attacks is equivalently transformed into error systems. By applying the approach of products convergence for infinite sub‐stochastic matrices, a sufficient condition for producing the flocking behavior is obtained. An upper bound of relative errors for agents' final positions is established, which depends on initial states, the topology structure and the weight function. Finally, simulation experiments verify the effectiveness of the theoretical results.

AbstractTwo heteroleptic uranyl(VI) complexes [UO2(L)(phen)] (1) and [UO2(L)(pypzH)] (2) [where, H2L=N2O2‐benzil bis(isonicotinoyl hydrazone) ligand, phen=1,10‐phenanthroline and pypzH=3‐(2‐pyridylpyrazole)] were synthesized and characterized by elemental analysis, mass spectrometry, UV‐Visible, 1H NMR, FT‐IR and TGA techniques. The time‐dependent density functional theory (TD‐DFT) calculations of both the complexes were carried out to obtain the insights into the structure and spectral properties. According to results obtained, the title complexes have highly distorted structures deviating from the expected hexagonal bipyramidal structures. The computed results show that the LUMO of the complex is mainly stabilized by uranium. Both the complexes exhibit similar UV‐Visible spectra within the region 325–600 nm with their intense bands at ∼450 nm primarily due to the HOMO→LUMO transitions. A weak absorption band which appears at ∼335 nm for each complex has been attributed to n→π* transition. In contrast to complex 2,the complex 1 exhibits maximum deviation from the Oyl‐U‐Oyl linearity.

Published: September 2022

AbstractDevising a simple, environmentally friendly, and reusable route for the [3+2] cycloaddition reaction of azides and nitriles to form tetrazoles is undoubtedly a challenging issue. Herein, a facile synthesis method for 5‐substituted‐1H‐tetrazoles was developed by treating nitriles with NaN3 in a betaine‐diol‐based deep eutectic solvent. This protocol offers products in very high yields, an easy work‐up procedure devoid of harmful organic solvents, and recyclability of the deep eutectic solvent, thereby making it environmentally benign.

Published: September 2022

AbstractLocal environment dependent photoluminescence (PL) of cerium incorporated GO nanoparticles (GO−Ce NPs) is investigated by using fluorescence quenching study in presence of aromatic nitro compounds (ANCs) and fluoride ion. Presence of trivalent and tetravalent cerium ions at the different locations of the GO based nanoparticles interact with ANCs and fluoride ions in a different manner depending upon the accessibility and local polarity of the excited cerium (III) ions. Proposed system is found to be most sensitive towards ortho‐nitrophenol (quenching efficiency 70.5 %) with a high constant value of KD and KS, 8.7 × 104 and 7.0 × 104 respectively. Herein, the fluorescence quenching study of GO−Ce NPS reveals the different mode of interactions between the fluorophoric moieties and quenchers.

Published: September 2022

AbstractMonophasic GdCrO3 nanoparticles have been fabricated by ethylene glycol‐assisted metal citrate precursor method. The as‐prepared nanoparticles have been characterized for phase purity, size and morphology by using powder X‐ray diffraction, transmission electron microscopy and scanning electron microscopic techniques. GdCrO3 nanoparticles showed excellent crystallinity with an average particle size of 78 nm and high specific surface area of 184 m2 g−1. The two band gap values of 1.9 eV and 2.3 eV were calculated using K−M function of the UV‐visible diffuse reflectance spectroscopy. Magnetic results of GdCrO3 nanoparticles possess the well defined ferromagnetic loop, which confirms the ferromagnetic characteristics of these nanoparticles. Our results further exhibit improved P−E loop for GdCrO3 nanoparticles showing ferroelectric behaviour at room temperature for the first time which indicates the presence of multiferroic nature. The dielectric constant and dielectric loss of sintered/unsintered pellet of GdCrO3 were measured as a function of frequency and temperature. Lastly, the humidity sensing parameters of GdCrO3 nanoparticles have also been reported.

Published: September 2022

AbstractThe further applications of liquid metals (LMs) are limited by their common shortcoming of silver‐white physical appearance, which deviates from the impose stringent requirements for color and aesthetics. Herein, a concept is proposed for constructing fluorescent core–shell structures based on the components and properties of LMs, and metal halides. The metal halides endow LMs with polychromatic and stable fluorescence characteristics. As a proof‐of‐concept, LMs‐Al obtained by mixing of LMs with aluminum (Al) is reported. The surface of LMs‐Al is transformed directly from Al to a multi‐phase metal halide of K3AlCl6 with double perovskites structure, via redox reactions with KCl + HCl solution in a natural environment. The formation of core–shell structure from the K3AlCl6 and LMs is achieved, and the shell with different phases can emit a cyan light by the superimposition of the polychromatic spectrum. Furthermore, the LMs can be directly converted into a fluorescent shell without affecting their original features. In particular, the luminescence properties of shells can be regulated by the components in LMs. This study provides a new direction for research in spontaneous interfacial modification and fluorescent functionalization of LMs and promises potential applications, such as lighting and displays, anti‐counterfeiting measures, sensing, and chameleon robots.

Published: September 2022

AbstractIntroductionSleep and diet are modifiable risk factors for Alzheimer's disease (AD) that may be salient areas for the development of preventive intervention strategies against dementia in people with mild cognitive impairment (MCI). Sleep disturbances account for up to 15% of the population attributable risk for AD. Diet influences sleep quality, such that diets high in sugars, fat, and processed food affect sleep quality and cognition in older adults. The combination of poor sleep and diet health may increase risk for dementia in people with MCI, yet it is unknown how intervening on diet may influence sleep health.MethodsThe MCI Sleep Study assesses longitudinal changes in objective and subjective measures of sleep between two investigational diet groups in the Brain Energy for Amyloid Transformation in Alzheimer's Disease study: the modified Mediterranean ketogenic diet (MMKD) and the American Heart Association diet. Objective sleep assessments include an in‐home sleep study using the WatchPAT Central Plus (Itamar Medical, Ltd) at baseline and the end of the 4‐month diet intervention. Subjective sleep questionnaires include the Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index. The MCI Sleep Study outcome measures include longitudinal change in cognitive performance, mood, behavior, and quality of life.ResultsStudy recruitment is currently ongoing. We hypothesize the low‐carb MMKD diet to have a beneficial impact on sleep health in individuals with MCI. Pre‐ and post‐diet changes in sleep metrics across diet groups will be examined using mixed effects analysis of variance models.DiscussionEarly assessment of chronic sleep and diet behaviors may be vital in understanding when interventions are necessary and the lifestyle modifications that should accompany future AD prevention and therapy recommendations.
Vision Zero in Norway
Authors: Elvik Rune 
Published: September 2022

AbstractThis chapter describes the adoption of Vision Zero in Norway and some of the impacts on transport safety policy that can be traced to it. These impacts concern the following:

the demand for improved knowledge about the effects of road safety measures,

the creation of a new forum for developing road safety policy,

the adoption of quantified road safety targets and a system for management by objectives based on road safety indicators,

the identification of roads suitable for conversion to motorways or to 2+1 roads based on the Swedish model,

the revision of speed limit policy and

the revision of standards for the design and use of guardrails.

It is argued that the adoption of Vision Zero has had a major impact on road safety policy in Norway and may have contributed to speeding up the decline in the number of traffic fatalities and serious injuries after the year 2000.
Student Engagement in Open, Distance, and Digital Education
Authors: Bond Melissa , Bergdahl Nina 
Published: September 2022

AbstractEngaging students in their learning, and within their learning community, is a key goal of educators. However, ongoing discussions about its nature, conceptualization, and measurement have led to a diffusion of the concept’s understanding, and ability to apply it within both research and practice. This chapter draws on theoretical and empirical primary and secondary ODDE research, and provides an overview of student engagement and disengagement, particularly as they relate to educational technology. The four dimensions of behavioral, affective/emotional, cognitive, and social (dis-)engagement are presented, alongside example indicators. In addition, a bioecological model of student engagement is explored with explicit links to digital learning. The chapter concludes by providing open questions and directions for future research, including further emphasis and exploration needed on the role of social engagement in ODDE contexts, as well as disengagement as a separate construct.
