AbstractBio‐manufactured eumelanin is investigated as a sustainable high‐char carbon additive for use with moldable high temperature resins. Blends of Bisphenol A poly‐ether‐ether‐ketone (PEEK)‐based phthalonitrile (PN) with 0–30 wt% melanin are prepared and characterized for their compositional, thermal, and mechanical properties. Although the char yield increases from 10 to 30 wt% melanin loading, the presence of melanin decreases the thermal stability compared to PN resin alone. Despite this, the melanin‐PN resins still maintain a very high char yield (>64%) up to 1000 °C under nitrogen. Rheology, thermal analysis, and mechanical measurements suggest off‐gassing of the melanin and increased crosslinking between the melanin and PN, leading to a lower flexural strength resin with higher additive loadings. Spectroscopic studies suggest possible interaction between melanin and PN during co‐curing, which ultimately can affect the processing and final properties of melanin‐additive composite materials.

AbstractFrontal polymerization (FP) has attracted increasing interest in recent years in various applications. This polymerization method can be very promising for the polymerization of thick materials with high fillers content in the range of 50–80% (weight) by local application of a reasonable amount of energy. In this work, recent advances in controllable and predictive behavior for photoinduced frontal photopolymerization are reported. Here, tert‐butyl peroxybenzoate (Luperox‐P) is selected to initiate thermal polymerization at depth because its high polymerization ability and its decomposition temperature is in a promising range, i.e., neither extremely high (monomer decomposition) nor very low (storage stability issues). Thermal imaging experiments are used to follow the temperatures in the samples in real time. The number of cured layers and the depth of cure are also determined. This paper investigates various factors such as the contents of both photo and thermal initiators, the light intensity, the fiber contents, the irradiation time, etc., resulting in a statistical design of experiments with the factors: 1) content of Luperox P and 2) the irradiation time used to investigate the influence on photoinduced frontal polymerization. Markedly, FP appears to be fully controllable for a storage‐stable, tunable 1K system.
Optimality of function spaces for kernel integral operators
Authors: Takáč Jakub 
Published: July 2023

AbstractWe explore boundedness properties of kernel integral operators acting on rearrangement‐invariant (r.i.) spaces. In particular, for a given r.i. space X we characterize its optimal range partner, that is, the smallest r.i. space Y such that the operator is bounded from X to Y. We apply the general results to Lorentz spaces to illustrate their strength.

AbstractThe increasing impact of severe weather over Europe on lives and weather‐sensitive economies can be mitigated by accurate 0–6 h forecasts (nowcasts), supporting a vital ‘last line of defence’ for civil protection and many other applications. Recognizing lack of skill in some complex situations, often at convective and local sub‐kilometre scales and associated with rare events, we identify seven recommendations with the aim to improve nowcasting in Europe by the national meteorological and hydrological services (NMHSs) by 2030. These recommendations are based on a review of user needs, the state of the observing system, techniques based on observations and high‐resolution numerical weather models, as well as tools, data and infrastructure supporting the nowcasting community in Europe. Denser and more accurate observations are necessary particularly in the boundary layer to better characterize the ingredients of severe storms. A key driver for improvement is next‐generation European satellite data becoming available as of 2023. Seamless ensemble prediction methods to produce enhanced weather forecasts with 0–24 h lead times and probabilistic products require further development. Such products need to be understood and interpreted by skilled forecasters operating in an evolving forecasting context. We argue that stronger co‐development and collaboration between providers and users of nowcasting‐relevant data and information are key ingredients for progress. We recommend establishing pan‐European nowcasting consortia, better exchange of data, common development platforms and common verification approaches as key elements for progressing nowcasting in Europe in this decade.

AbstractPurposeTo analyse and compare patients' and healthcare professionals' (HPs) perspectives concerning patient care pathways for painful osteoarthritis (OA).Patients and methodsWe performed a qualitative study of two focus groups corresponding to eight patients with painful OA and eight HPs involved in OA management.ResultsSix key themes emerged from the interviews: (1) representations of OA, (2) OA pain, (3) quality of life, (4) care pathways, (5) actors involved in the care pathway, and (6) treatments. Both groups considered general practitioners, pharmacists and physiotherapists to be first‐line HPs, and no well‐defined OA specialist was identified. Patients and HPs reported similar difficulties concerning the adaptation of management to individual cases, late diagnosis and treatment, whereas only patients mentioned financial issues. Communication difficulties were identified as a major problem both between patients and HPs, and between HPs. Patients reported a lack of knowledge concerning pain and OA. The coordination between the various HPs is required, with education on both pain and OA. Several possible solutions were put forward by both patients and HPs.ConclusionThe care pathways of patients with painful OA are complex, with an unclear definition of the roles of the various HPs and suboptimal coordination. The role of HPs should be defined and collaboration between HPs developed.

AbstractTumor budding (TB) is a strong biomarker of poor prognosis in colorectal cancer and other solid cancers. TB is defined as isolated single cancer cells or clusters of up to four cancer cells at the invasive tumor front. In areas with a large inflammatory response at the invasive front, single cells and cell clusters surrounding fragmented glands are observed appearing like TB. Occurrence of these small groups is referred to as pseudobudding (PsB), which arises due to external influences such as inflammation and glandular disruption. Using a combination of orthogonal approaches, we show that there are clear biological differences between TB and PsB. TB is representative of active invasion by presenting features of epithelial‐mesenchymal transition and exhibiting increased deposition of extracellular matrix within the surrounding tumor microenvironment (TME), whereas PsB represents a reactive response to heavy inflammation where increased levels of granulocytes within the surrounding TME are observed. Our study provides evidence that areas with a strong inflammatory reaction should be avoided in the routine diagnostic assessment of TB. © 2023 The Authors.

AbstractThis study investigated novel methods for treating the surface of nitrile‐butadiene rubber to enhance its stability and resistance to thermal oxidation and aggressive media. The rubber surface was modified using 1,1,2‐trifluoro‐1,2,2‐trichlorethane. The study found that the duration of the modification strongly affected specific properties of the rubbers examined. It was observed that surface modification with 1,1,2‐trifluoro‐1,2,2‐trichlorethane improved the properties of nitrile‐butadiene rubber. Subsequently, the impact of the modification duration on morphology, thermal resistance, and chemical resistance was presented.

AbstractHelp seeking is a key component of many systems of self‐regulated learning (SRL). Prior research has noted how motivational and other aspects of SRL relate to students' engagement in help seeking and endorsement of types of help seeking (i.e., adaptive, expedient, and avoidant). This study examines specific antecedents to help seeking—monitoring accuracy, perceived need for help, and value for help seeking—as both domain‐general (between students) and domain‐specific (within students) aspects of help seeking in a sample of upper elementary students. Drawing on self‐reports, teacher‐reports, and assessments, results show that antecedents' relations with help seeking vary at the level of measurement (within or between students), type of reporter (student vs. teacher), and characterization of help (adaptive vs. expedient). Results present a complicated picture of students' classroom help seeking, supporting some theoretical links and laying the stage for further study of help seeking across contexts among elementary students.

Published: July 2023

AbstractThe tendency of epoxy resins to form three‐dimensional structures can make them brittle, which restricts their use in various applications even if they have great mechanical properties. Due to the expansion of epoxy resin application to electric automotives and aerospace as carbon fiber resistance plastics (CRFPs), it is desirable to synthesize epoxy resins that is more impact resistant. Herein, the synthesis of flexible epoxy resin FMER‐F and FMER‐J is reported. These epoxy resins were based on bisphenol F and J diglycidy ether. The dimeric fatty acid modified epoxy resins (FMERs) were synthesized by reacting acid anhydride modified epoxy resins (AMERs) with dimeric fatty acids. To obtain thermosetting epoxy polymers, the epoxy resin was mixed with a curing agent and an accelerator and, subsequently, it was cured at a high temperature. The mechanical properties of various epoxy polymers were analyzed to evaluate the change in the performance of the materials. The flexural strength of the composition with 10 parts per hundred resin (phr) of FMER‐F increased by 21%. The impact strength of the composition with 30 phr of FMER‐J increased by 27%. FMERs were found to be used as toughening agents in epoxy resins and composites because of their ability to enhance mechanical properties.
Development and assessment of a novel servo‐controlled spraying system for real time adjustment of the orientation angle of the nozzles of a boom sprayer

Published: July 2023

AbstractBackgroundPesticide spray drift, which is the movement of pesticide by wind to any location other than the intended area, is hazardous to human, animal, food safety and environmental health. It is not possible to completely eliminate spray drift during spraying with field crop sprayers, but spray drift can be reduced by developing new technologies. The most common methods to reduce spray drift are carrying the droplets to the target with air‐assisted spraying, electrostatic spraying, preferring air induction nozzles and boom shields. With these methods, it is not possible to make a change on the sprayer depending on the wind intensity during spraying. In this study, a novel servo‐controlled spraying system was designed and developed to change the nozzle orientation angle in the reverse direction of the wind current to reduce the ground spray drift in real time and automatically in a wind tunnel. The displacement in the spray pattern (Dc) was used as a ground drift indicator for each nozzle to evaluate the spray drift.ResultsThe developed system, operated by LabVIEW software, calculated different nozzle orientation angles depending on nozzle types, wind velocities and spraying pressures. Orientation angles calculated for different test conditions achieved in reduction were up to 49.01% for XR11002 nozzle, 32.82% for AIXR11002 nozzle and 32.31% for TTJ6011002 nozzle at 400 kPa spray pressure and 2.5 m s−1 wind velocity.ConclusionThe developed system, which has a self‐decision mechanism, calculated the nozzle orientation angle instantaneously according to the wind velocity. It has been observed that the adjustable spraying nozzle system, sprayed with high precision towards the wind in the wind tunnel, and the developed system have advantages compared to conventional spraying systems. © 2023 The Authors.

Neighbourhood attachment, city attachment or beyond? Residential mobility and scales of place attachment in Shanghai, China
Authors: Lu Tingting , Kam Yui Chung , Chang Jiang , Mao Sanqin 
Published: July 2023

AbstractWith suburbanisation and gentrification becoming global phenomena, residential mobility has been incentivised and is extensively taken as a critical lens through which to understand the formation and variation of place attachment in different urban settings. Extant literature has suggested that the strength of place attachment is curvilinear across different geographical scales. However, limited research has investigated how processes and changes of residential mobility, embedded in different socioeconomic and structural settings, shape people's place attachment at the neighbourhood and city scales. To address this shortfall in the literature, this study employs a process‐based perspective by reconciling past housing experiences with that of the present to investigate how residential mobility affects place attachment based on a large‐scale survey in Shanghai in 2021. The findings show that the processual residential mobility relays profound influences on place attachment at different geographical scales. Specifically, homeownership secures residents' a privileged multi‐scale attachment. Meanwhile, access to state welfare housing in the past and at present, as well as residential moves driven by individual needs are more likely to engender a single‐scale attachment. Experiences with housing relocation and market rental exert negative influences on place attachment at both the city and neighbourhood scales. Both housing policy‐related structural factors and socioeconomic status have led to marginalised residential mobility, consequently entailing a sense of ‘placelessness’ in urban China.

AbstractSepsis and septic shock are still one of the most important medical challenges. Sepsis is an extreme and uncontrolled response of the innate immune system to invading pathogenesis. Resveratrol (3,5,4′‐trihydroxytrans‐stilbene), is a phenolic and non‐flavonoid compound naturally produced by some plants and fruits. The object of the current study is to systematically review the impacts of resveratrol and its mechanisms of function in the management of sepsis and its related complications. The guidelines of the Preferred Reporting Items for Systematic Review and Meta‐Analysis (PRISMA) statements were applied to perform the study (PROSPERO: CRD42021289357). We searched Embase, Web of Science, Google Scholar, Science Direct, PubMed, ProQuest, and Scopus databases up to January 2023 by using the relevant keywords. Study criteria were met by 72 out of 1415 articles screened. The results of this systematic review depict that resveratrol can reduces the complications of sepsis by affecting inflammatory pathways, oxidative stress, and modulating immune responses. Future human randomized clinical trials are necessary due to the promising therapeutic effects of resveratrol on sepsis complications and the lack of clinical trials in this regard.
Lane‐Hamilton syndrome
Authors: Grech Audrey K. , Yu Christiaan 
Published: July 2023

AbstractThe co‐existence of idiopathic hemosiderosis and celiac disease is Lane‐Hamilton Syndrome. This is a rare condition with only a few dozen cases reported to date. Its clinical presentation typically involves hemoptysis that can be life‐threatening in the acute phase. We report the uncommon case of the development of idiopathic pulmonary hemosiderosis almost a decade after the diagnosis of celiac disease. Delayed diagnosis led to recurrent episodes of large volume hemoptysis despite immunosuppressive therapy due to ongoing ingestion of gluten. High doses of glucocorticoids accompanied by a cell cycle inhibitor mycophenolate mofetil were required for treatment. A strict gluten free diet is vital to control the disease. We highlight the importance of identifying this syndrome and definitive treatment, including avoidance of dietary triggers in addition to conventional immunosuppressive therapy.

Published: July 2023

AbstractThis article is concerned with the robust tracking control for an uncertain micro‐hand actuator with Prandtl‐Ishlinskii hysteresis (PI hysteresis) by robust right coprime factorization (RRCF). Firstly, the PI hysteresis is modeled into the rubber micro‐hand actuator and a new hysteretic micro‐hand system is obtained. Secondly, by compensating the hysteresis part into the isomorphic subspace, the effect of hysteresis on micro‐hand system is transferred and the operator‐based robust controllers are designed to ensure that the robust stability of the whole system. Thirdly, the RRCF and terminal sliding mode control are combined for tracking control, and the nonsingular terminal sliding mode surface with integral terms is designed, which shorten the convergence time and improve the tracking performance. Finally, the effectiveness of the method is tested by the simulation of the micro‐hand system.
My father put them up there: Anthropogenic environmental change associated with abandoned river vessels in the Clarence River, NSW, Australia

Published: July 2023

AbstractThe Clarence River (New South Wales, Australia) was the main transport corridor for the timber and sugar cane industries operating in the catchment from the 1860s to the 1970s. Using archaeological, documentary, and oral historical resources we explore some of the anthropogenic impacts of these industries upon the fluvial geomorphology of the lower Clarence River. In particular, the deliberate abandonment of obsolete vessels on the river system is a focus. These discarded former cane and timber barges have been used as erosion control devices in several areas around the Harwood Island sugar mill, resulting in the accumulation of sediments and the establishment of mangrove environments in what were degraded areas.
Sustainable Development Goals in BRICS and G7 countries: Increasing accomplishments through policy synergies in four dimensions
Authors: Ofori Elvis Kwame , Appiah‐Opoku Seth 
Published: July 2023

AbstractThe United Nation's 17 Sustainable Development Goals (SDGs) represent aspirations for human development that necessitate the epiphany of a universal yet varied set of ethical values, social equity, sustainability, and healthy lifestyle within a clean, safe environment. However, recent events such as Covid‐19 and the Ukraine–Russia Impasse have been a bane to achieving these goals. Consequently, there is the need to find innovative ways to increase accomplishments. Given that the SDGs are inherently interconnected and that achieving one is a suitable springboard for achieving others, we hypothesize the whole SDGs in four dimensions: (i) environmental, (ii) economic, (iii) human development, and (iv) energy sustainability to aid in cost effective implementation and comparative analysis between BRICS and G7 countries. Proxying SDGs 3 and 4 with human development, SDG 8 with economic growth, SDG 13 with environmental sustainability, and SDG 7 with energy sustainability, we use panel data from 2000 to 2020. We conducted a thorough empirical investigation and used sophisticated econometric approaches—Driscoll–Kraay for the principal analysis and fixed effect for robustness check. From the analysis, we conclude that the policy frame of UN‐SDG is inconsistent within the panel (BRICS and G7 nations), suggesting that these policy instruments need a uniform harmonization in the policy framework. In conclusion, a policy framework must be created in such a manner that, while having the ability to improve the environment, the pattern of economic growth is preserved, and human progress pursues its goals with priority access to sustainable energy.
