AbstractCopper oxide nanoparticles (CONs) are synthesized using the leaf extract of Nyctanthes arbor‐tristis. They are further characterized using FE‐SEM and EDX techniques and successfully used for the removal of Congo Red (CR) dye. To enhance the removal efficiency, the effect of various parameters viz. shaking time, adsorbent dose, pH, etc. are studied. The kinetic model showed that the CR adsorption on CON followed the pseudo‐first‐order reactions. Langmuir isotherm modeling is best fitted and describes the CR‐CON adsorption system for CR dye in 90 min with Qmax at 333.33 (mg/g). At varying temperatures, the statistical physics model computed the number of bound CR dye molecules and the saturation adsorption capacity for both functional groups. At 298, 308, and 318 K, the values of “n” are 0.379, 0.358, and 0.328, respectively, which showed that CR molecules interacted with two and three functional groups of the CON surface through a horizontal adsorption orientation. The role and importance of suggested functional groups on dye adsorption as well as their thermodynamic characteristics are determined using a statistical physics model. The reused study is applied to the CON and their efficiency is excellent up to five cycles, making CON an effective pollution control material that may be commercialized in the near future.

AbstractUnderstanding community processes is essential to predict community dynamics and succession processes. To explore how shrub canopy removal frequency (hereafter ‘removal frequency’) and distance from shrubs affect herbs and grasses community assembly in a shrub‐encroached grassland, we carried out a 4‐year shrub canopy removal experiment with three removal frequencies (no removal, removal once, and removal twice per year) in aCaragana microphyllashrub‐encroached grassland, and assessed community assembly mechanisms directly beneath shrubs (0 m from shrubs, i.e., in the centre of the shrub) and in shrub interspaces (at least 2 m from shrubs) under each removal frequency treatment using both functional trait‐based and phylogenetic‐based approaches. Removal frequency positively affected standard effect sizes (SESs) of the mean pairwise distance (MPD) for multi‐trait, specific leaf area (SLA) and leaf dry matter content (LDMC), denoted by SES.MPDMulti‐trait, SES.MPDSLA, and SES.MPDLDMC, indirectly via regulating soil nitrogen (N) and soil carbon (C) content, while it negatively affected SES.MPDHeightindirectly via regulating soil available phosphorus (P) content. Distance from shrubs negatively affected SES.MPDHeightindirectly via regulating soil available P content, and negatively affected SES.MPDLDMCindirectly via regulating soil C content. The trait‐based approach was more powerful than the phylogenetic‐based one in explaining the responses of community assembly processes to environmental changes. These findings highlight the importance of shrub canopy removal and distance from shrubs in affecting soil nutrient status and consequently community assembly processes, which provides a new insight into how canopy removal or fertile island effects affect community assembly in the shrub‐encroached grassland regions.
Strained Ammonium Precursors for Radiofluorinations
Authors: Reissig Falco , Mamat Constantin 
Published: June 2022

AbstractThe increasing application of positron emission tomography (PET) in nuclear medicine has stimulated the extensive development of a multitude of novel and versatile techniques to introduce fluorine‐18, especially for the radiolabelling of biologically or pharmacologically active molecules. Taking into consideration that the introduction of fluorine‐18 (t1/2=109.8 min) mostly proceeds under harsh conditions, radiolabelling of such molecules represents a challenge and is of enormous interest. Ideally, it should proceed in a regioselective manner under mild physiological conditions, in an acceptable time span, with high yields and high specific activities. Special attention has been drawn to 2‐fluoroethyl and 3‐fluoropropyl groups, which are often the active sites of radiofluorinated compounds. Precursors containing an ammonium leaving group – such as a strained azetidinium or aziridinium moiety – can help to overcome these obstacles leading to a convenient and mild introduction of [18F]fluoride with high radiochemical yields.

AbstractThis research aims to describe the hybrid algorithm's effectiveness in predicting and optimizing the abrasive water jet machining (AWJM) parameter on flexible sheep wool reinforced polyester composites. Selected five parameters are transverse speed (TS), water jet pressure (WJP), nozzle stand‐off distance (NSoD), reinforcement weight percentage (wt%) and abrasive size (AS). In contrast, Surface Roughness (Ra) and Kerf Angle (Ka) are output performances. Multi objective optimization by ratio analysis (MOORA) is a tool is used for selecting and optimizing control variables. The most influential control variables are AS, WJP, TS, wt%, and NSoD, according to MOORA–Entropy feature selection results. The support vector machine algorithm (SVM) represents the AWJM process, and the model's performance is compared to SVM hybrid models. The differential evolutionary (DE) algorithm and the Entropy idea create a hybrid model. An SVM model is compared with the Hybrid SVM—Entropy model; hybrid improves prediction performance by 21.6%. When the MOORA—SVM—Entropy hybrid model is compared to the SVM model, it is revealed that the MOORA—SVM—Entropy hybrid model's prediction performance improves by 38.7%. According to the MOORA—Entropy approach, the optimal control variables are A2, B1, C1, D3, and E1.

AbstractAimPrevious research shows that telephone consultation is useful in suicide prevention, substance use disorder, and other mental illnesses. However, no study has been conducted with a specific focus on telephone consultation for patients with bipolar disorder (BPD). Therefore, this study investigates the utilization of telephone consultation by patients with BPD and their families and analyzes the consultation contents to identify specific issues that they face.MethodsWe investigated a record book of telephone consultation conducted between 2013 and 2019 provided by the Japanese Alliance of Bipolar Disorder, which is a self‐help group in Japan specializing in BPD. The main themes regarding consultation were extracted and labelled as diagnosis, symptoms, treatment, laws and social support, interpersonal relations, social life, other people with BPD, and others, with up to three items being labeled per consultation.ResultsA total of 3540 consultations were sought, and consulters who were patients accounted for 74% of the calls. The largest number of consultations were those related to symptoms (1522), followed by interpersonal relations (1003), social life (896), and treatment (797). There was a significant difference in the distribution of consultation contents between patients and their families (χ2 = 44.595, p < 0.0001).ConclusionMost consultations by patients with BPD were about their psychiatric symptoms. Consultation contents differed between patients and families, with patients focusing more on their own social life and families focusing more on the treatment of BPD. These findings could help health‐care professionals in formulating effective psychoeducation and psychotherapy programs.
Thermal modeling for supporting firefighting and emergency response planning

Published: June 2022

AbstractThis literature review looks at the various types of approaches to industrial storage tank fires and evaluates how quantitative consequence analysis with thermal modeling may aid in the development of industrial site fire preplans and emergency response planning guidelines. Emergency response planners may employ the use of thermal contours on plot plans generated by available consequence modeling software. Such performance‐based approaches can effectively take into account the associated sociotechnical factors and site‐specific hazards. With these approaches, the planners can identify appropriate preventative actions and responses, such as the activation of cooling on adjacent equipment, as well as establishing safe approach/muster point distances from hazardous sources of thermal heat stress.

Published: June 2022

AbstractThe radar system is a fundamental part of the launch site ground equipment, and its health status is critical to the success of testing tasks and launch missions at aerospace launch sites. The health status assessment of radar systems is, however, challenging due to multiple health indicators of its components and epistemic uncertainty associated with the elicited data. In this article, a fuzzy analytic hierarchy process method, which combines the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation methods, is put forth to assess the health status of radar systems at aerospace launch sites. In the first place, the four‐layer hierarchical structure, including the system, subsystem, performance indicator, and parameter index layers, of a real‐world radar system at an aerospace launch site is constructed. The AHP is, then, leveraged to identify the weights of each layer of the hierarchical structure. By eliciting the data of parameter indices as fuzzy numbers and using the fuzzy comprehensive evaluation method to calculate the layer‐by‐layer health status of the hierarchical structure, the health grade membership of the radar system is calculated. The health status of the radar system is, then, assessed in accordance to the maximum membership principle. A new importance metric is proposed to assess the influence of parameter indices on the current system's health status. The results of the importance metric can provide valuable insight for reliability enhancement and health management of the radar system.

Published: June 2022

RationaleThe anabolic steroid 5α‐androst‐2‐en‐17‐one (2EN) is sold as a prohormone and has been investigated regarding its potential as a steroidal aromatase inhibitor. The administration of 2EN was detected in a doping control sample in 2015, and investigations into its metabolism allowed for the identification and characterization of three urinary metabolites. Unfortunately, the utility of the main metabolite 2β,3α‐dihydroxy‐5α‐androstan‐17‐one for doping control purposes was hampered under routine doping control conditions due to chromatographic issues, thus warranting further studies on the metabolism of the prohibited substance.MethodsThe metabolism of 2EN was reinvestigated after oral administration of twofold‐deuterated 2EN employing hydrogen isotope ratio mass spectrometry (IRMS) in combination with high‐accuracy/high‐resolution mass spectrometry. After a single dose of 50 mg of doubly labeled 2EN, urine samples were collected for 9 days. All samples were processed using routine doping control methods for IRMS analysis, and all detected metabolites were further characterized by mass spectrometry‐based investigations.ResultsMore than 15 different metabolites still containing the deuterium label were detected after administration. The presence of steroids exhibiting a 5β‐configuration was unexpected as the administered 2EN features a 5α‐configured pharmacophore. Further investigations corroborated a significant impact of the administered 2EN on etiocholanolone and 5β‐androstanediol. Seven metabolites of 2EN not present as endogenous compounds were identified as potential candidates for routine doping controls and could be detected for up to 9 days after administration.ConclusionsThe new metabolites identified in this study enable the detection of the misuse of 2EN for up to 9 days. The conversion of a 5α‐steroid to urinary metabolites with 5β‐configuration has not been reported so far and should be further investigated.
Robust consensus of uncertain multi agent systems with one‐sided Lipschitz nonlinearity
Authors: Ramachandran Karthi , Juang Jyh‐Ching 
Published: June 2022

AbstractThis article develops protocols for the consensus of an uncertain nonlinear multi‐agent system that satisfies the one‐sided Lipschitz and quadratic‐inner bounded conditions. Fully distributed consensus protocols with observer‐based and observer‐less schemes are investigated. For the observer‐based system, a full order Luenberger observer is designed. To overcome the difficulties of designing the controller and observer‐based controller gains, sufficient conditions are provided with a complete linear matrix inequality characterization. Finally, two simulation examples are provided to illustrate the effectiveness of the proposed approach.

AbstractThe present work reports the synthesis of nanostructured thin films on glass substrate by dip coating. The thickness of thin film was varied by varying the no. of dips of glass substrate in the aqueous solution of Ca(NO3)2⋅4H2O and NaOH. Deposited films were studied by the X‐Ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), Fourier Transform Infrared Spectroscopy (FTIR), and Ultraviolet‐visible (UV‐Vis) spectroscopy techniques. The thickness of film was increased almost linearly with number of dips. Accordingly, the nanocrystalline size and band gap was varied. Interestingly the nanoflower like structure of calcite thin films was observed in FESEM and that varied with the thickness of film. The calcite thin film formation was discussed in terms of reactivity due to nanostructure and surface structure was discussed in terms of nucleation and growth of film on the substrate. Finally, the implications of these results in terms of microstructurally tuned nano calcite thin films development for prospective futuristic industrial applications are highlighted.
Unveiling thecb‐typeIntramolecular [3+2] Cycloaddition Reactions of Fluorinated Azomethine Ylides to Ester Carbonyls with a Molecular Electron Density Theory Perspective
Authors: Domingo Luis R. , Ríos‐Gutiérrez M. , Acharjee Nivedita 
Published: June 2022

AbstractThe carbenoid‐type (cb‐type) intramolecular [3+2] cycloaddition (IM32CA) reactions of four fluorinated azomethine ylides (AYs) bearing an ester carbonyl substituent have been studied from the molecular electron density theory (MEDT) perspective. The presence of two fluorine atoms in these species changes thepseudodiradicalstructure of the simplest AY to that of a carbenoid one, according to thecb‐typemolecular reactivity of these IM32CA reactions. These IM32CA reactions present low activation energies, lesser than 3.0 kcal ⋅ mol−1, and a strongly exothermic character, more than −34.0 kcal ⋅ mol−1, showing a complete chemo‐ and regioselectivity. The presence of the electron‐withdrawing −CN group at the aryl ester framework increases the global electron density transfer (GEDT) at the transition state structure (TS), which fluxes from the nucleophilic AY moiety to the electrophilic carbonyl ester, diminishing the activation energy by 2 kcal ⋅ mol−1relative to that of the phenyl substituent. Electron Localization Function and Atom‐in‐Molecules topological analyses of the most favorable TSs show the early character of thesecb‐typeIM32CA reactions. The present MEDT study makes it possible to establish that the carbenoid structure of these fluorinated AYs together with their supernucleophilic character are responsible for the high reactivity and selectivities shown by these three‐atom‐components participating incb‐type32CA reactions towards carbonyl compounds.
The Distant Past of a Distant Past …: Perception and Appropriation of Deep History During the Iron Ages in Northern Germany (Pre-Roman Iron Age, Roman Iron Age, and Migration Period)
Authors: Schumann Robert 
Published: June 2022

AbstractThe reuse of ancient burial grounds in prehistory is a practice that has long been testified through archaeological investigations for several periods in European prehistory. As burial mounds form a distinctive feature in the landscape—to some extent even today—the perception and appropriation of these does not come as a great surprise. Still, this appropriation and reuse for burial or other non-funerary activities offers insights into cultural practices that have only recently been frequently discussed in the field. Normally these reuses are interpreted as ancestor veneration—be it of putative or real ancestors—or the use of these monuments is considered in terms of legitimation of power structures and social distinction by elites. The diversity, frequency, and distribution of such reuses nevertheless indicate that through time older monuments are reused not only by social elites but also by other parts of these societies, and by different forms of communities. This paper will focus on northern Central Europe during the Iron Ages (Pre-Roman Iron Age, Roman Iron Age, Migration Period) and discuss how different societies (‘culture groups’) reused ancient burial places as well as other locations and objects through time and space. These findings show the importance of the long-gone dead in Iron Age Europe and form the basis for a discussion of different possible interpretations of appropriations of the distant past.
Art Therapy
Authors: Nielsen Fran 
Published: June 2022

AbstractThe use of group art therapy, individual art therapy and family art therapy in an inpatient child and adolescent mental health services unit will be described, including images and consumer feedback to demonstrate effectiveness. The artworks made in art therapy can reveal hidden dysfunction in the young person and/or their family members. Recent trauma research supports capacity to access this material safely through non-verbal visual communication. Family art therapy has been a useful intervention to support the identification of illness in a parent, to improving attunement between the parent and the child and for the parent to detach from their child’s symptoms by agreeing to get treatment for themselves. If the patient cannot separate from the illness in the parent, their symptoms will persist.

Published: June 2022

AbstractThis experimental study investigates the effects of process parameters for 3D printing polylactic acid (PLA) samples on both the mechanical properties obtained and the energy consumption in the fused deposition modelling (FDM) process. The explained experimental activities provide an in-depth evaluation of all the strategies adopted in different temperatures and scan speed strategies. The results, extracted in tensile strength, ultrasonic inspection (UT), and specific energy consumption (SEC), highlight the printing parameters that mainly affect the mechanical characteristics of the final workpieces and the energy consumption to find an appropriate energy-saving energy strategy for the PLA additive manufacturing process. The results indicate a more excellent uniformity of the molded material, reducing the printing time and total energy consumption at high speeds (V = 110 mm/s) and one level of temperature (T = 215 °C). A new efficiency index has been introduced to release guidelines to pursue the best setup compromise.
