Published: January 2022

AbstractHere, we studied the self‐assembly and chiroptical properties of four C2‐symmetric molecules bearing terephthaloyl (TLF−C4 and TLF−C12) and benzene‐1,4‐dicarbonyl core (BLF−C4 and BLF−C12). β‐turn in the aggregates of TLF−C4 and TLF−C12 was found irrespective of the amount of water as anti‐solvent in methanol (MeOH). Interestingly, chiroptical properties can be switched from β‐turn to twisted β‐sheet secondary structure in BLF−C4 and BLF−C12 beyond a certain amount of water in MeOH. Detailed studies suggested lamellar arrangement of the TLF−C4 gelators with a β‐turn led to the formation of right‐handed coiled‐coil helical fibers. However, left‐handed coiled‐coil twisted fibers were formed by lamellar packing (twisted β‐sheet) of BLF−C4. In addition, TLF−C12 gel in methylcyclohexane (MCH) revealed shape persistent gelation. Rapid dynamic equilibrium between association and dissociation of non‐covalent interactions in BLF−C12 gel in MCH resulted in thixotropic and, in turn, injectable behavior.

Published: January 2022

AbstractThis work demonstrates the application of a Fe3O4/zeolitic imidazolate framework 67 (ZIF67) micromotor for improved catalytic degradation of organic pollutants. The micromotors were fabricated by simple adsorption of Fe3O4 nanoparticles on the surface of ZIF67 microparticles, which were synthesized by wet chemistry method. Both Fe3O4 and ZIF67 perform asymmetric decomposition of H2O2 to achieve bubble propulsion of the micromotors. The ferromagnetism of Fe3O4 enables easy directional control of the micromotor. The porous structure of ZIF67 benefits the enrichment of pollutant molecules around the micromotors, facilitating the efficient catalytic degradation. With intensified interaction between active sites and pollutant molecules due to self‐propelled motion and synergistic catalysis of iron in Fe3O4 and zinc ions in ZIF67, the micromotors exhibit enhanced degradation activity of methylene blue as compared to the pure Fe3O4 or ZIF67 counterparts without autonomous motion. This research can be extended to developing other metal‐organic frameworks (MOF)‐integrated micromotors for the environmental applications.

Published: January 2022

AbstractSelf‐compacting concrete (SCC) is a fluid concrete designed to flow freely through reinforcements in order to completely fill the formwork. The appearance of this type of concrete increases the need to precisely characterize its compressive strength as a function of their behavior during flow. This article summarizes the use of artificial neural networks for the modelization of compressive strength, at 28 days, of SCC based on rheological parameters found during empirical tests (slump flow diameter, H2/H1 ratio of L‐Box, and V‐Funnel flow time) and the values of plastic viscosity and the yield stress. The objective of this numerical and experimental study is to find an optimal model to modelize the compressive strength. Thus, the results obtained after training of several models are showed that the architecture of the optimum with two hidden layers model is 5‐50‐50‐1 with a Pearson's correlation R = 97.58%.

Published: January 2022

AbstractIn this research, we studied a roller‐compacted concrete (RCC) arch dam which was reinforced during the construction period to investigate the properties of mechanical parameters of the dam concrete after long‐term operation. Firstly, multiple methods involving core drilling, computerized tomography (CT), spectral analysis of the surface wave (SASW) of elastic waves, and an on‐site inspection were adopted to detect the quality of the dam concrete, which was followed by a forward‐analysis of the measured displacement of the arch dam and the water pressure component of the measured displacement was separated through regression analysis of statistical model of radial horizontal displacement. Subsequently, an optimization inversion of the elastic modulus of the dam body and dam foundation was conducted using a hybrid optimization method. The results showed that the compressive strength of the concrete in the body of the reinforced arch dam was over 30 MPa and the inversion results for the elastic modulus of the dam body were in the range of 30.1 ~ 33.3 GPa. According to the research results of multi‐source inspected and monitoring data during the operation period, the results suggest that the performance of the concrete of the dam body is in accordance with design requirements and the reinforced arch dam is properly operated.

AbstractCooking oil fumes (COFs) are the main pollutants in kitchen and indoor air, which threaten human health. Exposure to COFs may lead to respiratory diseases and impair pulmonary function. To investigate the toxicity of COFs on human bronchial epithelial cells (Beas‐2B) and explore the underlying mechanisms, MTT assay was conducted to detect the viability of Beas‐2B. Intracellular reactive oxygen species (ROS) levels and nitric oxide (NO) levels were determined with DCFH‐DA assay and DAF‐FM assay. The expression of genes involved in inflammation were measured with quantitative real‐time PCR (qRT‐PCR). The phosphorylation and the expression of proteins related to Mitogen‐activated protein kinase (MAPK), NF‐κB signaling pathways were measured with western blot. Our results revealed that COFs decreased cell viability, increased the ROS levels and NO levels and induced apoptosis in Beas‐2B cells. The results of qRT‐PCR and western blot showed that the expression of NLRP3, p65, iNOS, IL‐1β, and the factors related to oxidative stress and inflammation increased, NF‐κB signaling pathway and MAPK signaling pathway were activated. This study provided some useful information to evaluate the toxicity of COFs and revealed the possible mechanism for the damage on respiratory system induced by COFs.
Functional Group Positions and Contact Behavior in Problem-Solving Groups
Authors: Bachmann Thomas 
Published: January 2022

AbstractThis article in the journal Gruppe. Interaktion. Organization (GIO) deals with the application of the theory of functional psycho-dynamic positions by Raoul Schindler on problem-solving groups. Until now, there has been no empirical research substantiating this model and the emergence of the group positions. To do so, the relationship between the functional group positions and members’ contact behavior was examined with a sociometrical approach. A study with 138 participants from 22 groups was conducted. The results clearly confirm the model and show typical contact behavior patterns for each group position. Finally, types of informal group structures were compared in regards to group performance and practical applications for agile teams and shared leadership.
Moderators of Cognitive Behavioral Treatment for Insomnia on Depression and Anxiety Outcomes
Authors: Mirchandaney Riya , Barete Raul , Asarnow Lauren D. 
Published: January 2022

Abstract
Purpose of Review
With a focus on reviewing adequately powered randomized controlled trials, we present recent research on the potential of cognitive behavioral therapy for insomnia (CBT-I) to improve depression and anxiety outcomes among patients with insomnia and one of the following comorbid psychiatric disorders: major depressive disorder (MDD), generalized anxiety disorder (GAD), or posttraumatic stress disorder (PTSD). We also examine potential moderators of CBT-I on depression and anxiety outcomes in this population.

Recent Findings
Despite high comorbidity rates, current behavioral and pharmacological treatments for MDD, GAD, and PTSD do not substantially target or improve insomnia symptoms; residual insomnia is exceedingly common even among patients who experience remission. Insomnia plays a critical role in the onset and maintenance of depression and anxiety, and treating insomnia with CBT-I may improve global outcomes for patients with MDD, GAD, and PTSD.

Summary
CBT-I is superior to traditional depression/anxiety treatment in improving insomnia symptoms among patients with comorbid psychiatric disorders. Results are mixed on whether CBT-I (either alone or augmented with depression/anxiety treatment) is effective in improving overall MDD, GAD, and PTSD outcomes. Evening circadian preference and depression/anxiety symptom severity may moderate the effect of CBT-I on depression and anxiety outcomes.

Published: January 2022

SamenvattingGGD Gelderland-Zuid voerde eind 2017 voor de derde keer de Kindermonitor uit in de veertien gemeenten van haar werkgebied om de gezondheid en leefstijl van nul- tot twaalfjarigen in beeld te brengen. Ouders vulden hiervoor een vragenlijst in over hun kind. De resultaten van dit onderzoek gebruiken de gemeenten bij het formuleren van hun beleid. De Gezonde School-adviseurs verzochten schoolgezondheidsrapporten te maken. Om voldoende respons per school te verkrijgen was een wijziging in de wervingsmethode nodig. Voor 49 scholen in het primair onderwijs bleek de respons voldoende om een digitaal schoolrapport te ontwikkelen, waarmee het Gezonde School-beleid onderbouwd kan worden versterkt.

SamenvattingKunstobservatie in de opleiding geneeskunde bevordert het observatievermogen en de sociaal-emotionele vaardigheden van studenten. Wij onderzochten de plaats van kunstgerelateerd onderwijs in de geneeskundefaculteiten in Nederland. Zes van de acht geneeskundefaculteiten in Nederland hebben een vorm van kunstobservatie in het curriculum opgenomen. In de twee overige faculteiten is deze vorm van kunstonderwijs in ontwikkeling. De vorm, duur en verplichting van dit onderwijs verschillen tussen de geneeskundefaculteiten. Onderzoek naar de uitkomsten van kunstobservatie is schaars. Landelijke samenwerking biedt kansen gezamenlijk het effect te bepalen van kunstobservatie op analytische en observationele vaardigheden van studenten.

Authors: Aalbers Marloes , de Wit Bas 
Published: January 2022

SamenvattingDe afgelopen jaren heeft het beroep buurtsportcoach zich ontwikkeld van organisator en begeleider van sportactiviteiten voor jeugd, tot verbinder van mensen en organisaties in verschillende domeinen, zoals de gezondheidszorg. De focus ligt nog altijd op het inzetten van sport én bewegen. Buurtsportcoaches begeleiden mensen bij het veilig bewegen en vervullen een brugfunctie tussen bijvoorbeeld valpreventieprogramma’s en zelfstandig bewegen in de wijk. Deze veranderingen in hun opdrachten en doelstellingen gaan samen met een ontwikkeling van de beroepsgroep en een nieuw functieprofiel.
Monitoren en evalueren van een complex sportbeleidsinstrument: de buurtsportcoach

Published: January 2022

SamenvattingIn dit artikel bespreken we op welke wijze het model van Jolley voor de planning, implementatie en evaluatie van complexe lokale gezondheidsprogramma’s is toegepast bij een evaluatieonderzoek naar de lokale implementatie van de Brede Impuls Combinatiefuncties (BIC). Met de BIC konden gemeenten met cofinanciering van het rijk lokaal buurtsportcoaches aanstellen. Gemeenten hadden de vrijheid de buurtsportcoaches in te zetten, passend bij de lokale situatie. Door de grote lokale verschillen die hierdoor ontstonden was het niet goed mogelijk een traditionele vorm van evaluatie, zoals een effectonderzoek, toe te passen. Op basis van het model van Jolley hielden de onderzoekers rekening met de implementatie van de BIC op meerdere niveaus (macro, meso, micro), het belang van terugkoppeling tussen en binnen de niveaus, de verschillende perspectieven van betrokkenen en de invloed van de lokale context op de implementatie van de BIC. We reflecteren op de wijze waarop de onderliggende principes van het model van Jolley hebben geholpen dit grootschalige evaluatieonderzoek uit te voeren. Ondanks enkele concessies aan de uitgangspunten van Jolley blijkt het model grotendeels geschikt voor de evaluatie van een complex programma als de BIC.
Techno-economic analysis of an enhanced anaerobic digester in the Andean area of Peru
Authors: Jaeger Adriana , Blanchard R. E. 
Published: January 2022

AbstractThis paper aims to determine the economic and technical feasibility of developing a thermally enhanced digester in the Andean area using solar collectors. Communities in the rural area of the Andes lack access to electricity and other basic services which impact negatively on their everyday life and exposes them to harmful and inefficient fuels. Several experiences with anaerobic digestion prove that this technology could be applied in the Andean area, although its performance is limited due to low temperatures. To overcome this constraint, an enhanced digester was modelled and simulated using TRNSYS Software. The system consisted of two solar collectors, a storage tank and a digester with a wrapped-around heat exchanger. The average digester temperature in the simulation was 30.7 °C. The enhanced temperature was used in a model to calculate the daily biogas production. The Net Present Value and Internal Rate of Return were calculated and confirm the economic viability of the project. The biogas production fully covers the requirements of the system for household cooking and lighting, making a significant social impact. This simulation indicates that it is technically possible to develop an enhanced digester in the Andean area that is economically viable as well.
On the interaction of axial and bending loads in the weld root fatigue strength assessment of load-carrying cruciform joints
Authors: Ahola Antti , Hamidreza Rohani Raftar , Björk Timo , Kukkonen Olavi 
Published: January 2022

Abstract
Current design standards and recommendations incorporate the nominal stress system for assessing the fatigue strength capacity of load-carrying cruciform (LCX) joints with the fillet welds and failing from the weld root. Thus far, bending-loaded joints have not been addressed in these standards. The aim of the present study is to investigate the fatigue performance of LCX joints subjected to cyclic axial and bending loads. Firstly, fatigue test data sets of such joints subjected to axial loading and bending loads in the adjoined plate component are extracted from the literature, and statistical analyses are carried out to evaluate the fatigue strength capacity using the nominal weld stresses (NWSs). Secondly, experimental fatigue tests are carried out on LCX joints made of ultra-high-strength steel (UHSS) grade using constant amplitude loading and subjected to combined axial and bending load to study the load interaction effects on the fatigue strength capacity. The results showed that the FAT36 detail category for the weld root failures is applicable for bending-loaded joints when applying NWSs calculated on the basis of effective throat thickness of weld and assuming linear-elastic stress distribution over the joint section. The effective notch stress analyses showed unconservative results for the tested joints, when applying FAT225 design curve with the reference radius of rref = 1.0 mm.
ASN-SMOTE: a synthetic minority oversampling method with adaptive qualified synthesizer selection
Authors: Yi Xinkai , Xu Yingying , Hu Qian , Krishnamoorthy Sujatha , Li Wei , Tang Zhenzhou 
Published: January 2022

AbstractOversampling is a promising preprocessing technique for imbalanced datasets which generates new minority instances to balance the dataset. However, improper generated minority instances, i.e., noise instances, may interfere the learning of the classifier and impact it negatively. Given this, in this paper, we propose a simple and effective oversampling approach known as ASN-SMOTE based on the k-nearest neighbors and the synthetic minority oversampling technology (SMOTE). ASN-SMOTE first filters noise in the minority class by determining whether the nearest neighbor of each minority instance belongs to the minority or majority class. After that, ASN-SMOTE uses the nearest majority instance of each minority instance to effectively perceive the decision boundary, inside which the qualified minority instances are selected adaptively for each minority instance by the proposed adaptive neighbor selection scheme to synthesize new minority instance. To substantiate the effectiveness, ASN-SMOTE has been applied to three different classifiers and comprehensive experiments have been conducted on 24 imbalanced benchmark datasets. ASN-SMOTE is also extensively compared with nine notable oversampling algorithms. The results show that ASN-SMOTE achieves the best results in the majority of datasets. The ASN-SMOTE implementation is available at: https://www.github.com/yixinkai123/ASN-SMOTE/.
Dual-filtering (DF) schemes for learning systems to prevent adversarial attacks
Authors: Dasgupta Dipankar , Gupta Kishor Datta 
Published: January 2022

AbstractDefenses against adversarial attacks are essential to ensure the reliability of machine-learning models as their applications are expanding in different domains. Existing ML defense techniques have several limitations in practical use. We proposed a trustworthy framework that employs an adaptive strategy to inspect both inputs and decisions. In particular, data streams are examined by a series of diverse filters before sending to the learning system and then crossed checked its output through anomaly (outlier) detectors before making the final decision. Experimental results (using benchmark data-sets) demonstrated that our dual-filtering strategy could mitigate adaptive or advanced adversarial manipulations for wide-range of ML attacks with higher accuracy. Moreover, the output decision boundary inspection with a classification technique automatically affirms the reliability and increases the trustworthiness of any ML-based decision support system. Unlike other defense techniques, our dual-filtering strategy does not require adversarial sample generation and updating the decision boundary for detection, makes the ML defense robust to adaptive attacks.
Adaptations, Safety Factors, Limitations and Trade-Offs in Human Exercise Performance
Authors: Marino Frank E 
Published: January 2022

Abstract
Objectives
This review will describe how human exercise performance at the highest level is exquisitely orchestrated by a set of responses by all body systems related to the evolutionary adaptations that have taken place over a long history. The review will also describe how many adaptations or features are co-opted (exaptations) for use in different ways and have utility other than for selective advantage.

Methods
A review of the literature by relevant search engines and reference lists in key published articles using the terms, performance, limitations, regulation, trade-offs as related to exercise, indicates that there are at least three areas which could be considered key in understanding the evolutionary basis of human exercise performance.

Results
First, there is a basic assumption that exaptations have limitations or capacities which cannot be exceeded which in turn will limit our physical performance. Second, it is thought that some biological systems and tissues have additional capacity which is rarely fully accessed by the organism; referred to as a safety factor. Third, there are biological trade-offs which occur when there is an increase in one trait or characteristic traded for a decrease in another.

Conclusions
Adaptations have resulted in safety factors for body systems and tissues with trade-offs that are most advantageous for human performance for a specific environment.
Preliminary Evaluation of Natural Antibacterial Clays for Treating Wound Infections
Authors: Williams Lynda B. , Schmidt-Malan Suzannah M. , Patel Robin 
Published: January 2022

AbstractThe overuse of antibiotics in medicine has led to concerns over management of wound infections where antibiotic-resistant bacteria are involved. Wound infections exhibit both acquired and biofilm-associated antibiotic resistance; innovative non-antibiotic therapeutic and preventive treatments are needed to limit emergence of conventional antimicrobial resistance and to address biofilm-associated resistance. Toward this goal, natural antibacterial clays have been identified that are effective at killing drug-resistant human pathogens in planktonic and biofilm states, in vitro. To move toward clinical testing of antibacterial clays, the present study was conducted to evaluate the topical application of a natural antibacterial clay to wounds in mice experimentally infected with methicillin-resistant Staphylococcus aureus (MRSA). Five preliminary animal trials were conducted to test various methods of applying hydrated antibacterial clay to infected wounds. None of the experiments yielded significantly reduced MRSA infection in vivo, compared to controls. Several hypotheses were tested to explore the diminished clay antibacterial activity in vivo including: (1) pH and Eh of mineral-bacterial suspensions may differ in wound fluids compared to growth media; (2) antibacterial reactants may complex with components of the wound; (3) hydrated clays may dry out in the wound; and (4) limited dissolved oxygen may reduce Fenton reactions. Ancillary in vitro tests were performed to explore these hypotheses. Results indicate that the clay application to wounds may require enhanced oxidation and possibly a longer treatment regimen. The experimental results foster understanding of the natural clay–bacterial interactions in wounds and may improve designs for medicinal applications.
The carnality of power
Authors: Adebanwi Wale 
Published: January 2022

AbstractIn ‘Provisional notes on the postcolony’, Achille Mbembe argues that obscenity and grotesquery are essential characteristics of postcolonial regimes of domination and subordination. This article attempts to extend this insight for the study of contemporary African social formations. Drawing on examples from Central, Southern and West Africa, the article reflects on Mbembe’s particular emphasis on thecarnality of power, especially power’s ability to (over-)carnalize social relations, by further demonstrating why this is useful for understanding the relations of domination and subordination in Africa.
