AbstractAimWhether a laparoscopic procedure can contribute to the improvement of clinical outcomes in obese patients with stage II/III rectal cancer compared to an open procedure remains unclear.ObjectiveThis study evaluated the technical and oncological safety of laparoscopic surgery versus open surgery in obese patients (body mass index [BMI] ≥25 kg/m2) with rectal cancer.Patients and MethodsData were collected from patients with pathological stage II/III rectal cancer and analyzed. Operations were performed via laparoscopic or open surgery from 2009 to 2013. A comparative analysis was performed after applying propensity score matching to the two cohorts (laparoscopic group and open group). The primary endpoint was 3‐y relapse‐free survival (RFS).ResultsOverall, 524 eligible cases were collected from 51 institutions. Equal numbers of propensity score‐matched patients were included in the laparoscopic (n = 193) group and open (n = 193) group. Although the rate of D3 lymph node dissection did not differ between the laparoscopic group (87.0%) and the open group (88.6%), the median number of harvested lymph nodes was significantly lower in the laparoscopic group versus open group (17.5 vs 21, P = 0.0047). The median postoperative hospital stay was also significantly shorter in the laparoscopic group (14 d) vs the open group (17 d) (P = 0.0014). Three‐y RFS was not significantly different between the two groups (hazard ratio 1.2454, 95% confidence interval 0.9201–1.6884, P = 0.4689).ConclusionThe short‐ and long‐term results of this large cohort study (UMIN ID: UMIN000033529) indicated that laparoscopic surgery in obese rectal cancer patients has advantageous short‐term outcomes and no disadvantageous long‐term outcomes.

AbstractSerological assay for coronavirus 2019 (COVID‐19) patients including asymptomatic cases can inform on disease progression and prognosis. A detection method taking into account multiplex, high sensitivity, and a wider detection range will help to identify and treat COVID‐19. Here we integrated color‐size dual‐encoded beads and rolling circle amplification (RCA) into a bead‐based fluorescence immunoassay implemented in a size sorting chip to achieve high‐throughput and sensitive detection. We used the assay for quantifying COVID‐19 antibodies against spike S1, nucleocapsid, the receptor binding domain antigens. It also detected inflammatory biomarkers including interleukin‐6, interleukin‐1β, procalcitonin, C‐reactive protein whose concentrations range from pg mL−1 to μg mL−1. Use of different size beads integrating with RCA results in a tunable detection range. The assay can be readily modified to simultaneously measure more COVID‐19 serological molecules differing by orders of magnitude.

Published: July 2022

AbstractCrystalline metal oxide nanosheets show exceptional catalytic performance owing to the large surface‐to‐volume ratio and quantum confinement effect. However, it is still a challenge to develop a facile and general method to synthesize metal oxide nanosheets. Herein, we report a cocrystallization induced spatial self‐confinement approach to synthesize metal oxide nanosheets. Taking the synthesis of SnO2as an example, the solvent evaporation from KCl and SnCl2solution induces the cocrystallization of KCl and K2SnCl6, and the obtained composite with encapsulated K2SnCl6can be in situ converted into SnO2nanosheets confined in KCl matrix, after water washing to remove KCl, porous SnO2nanosheets can be obtained. Notably, a series of metal oxide nanosheets can be obtained through this general and efficient green route. In particular, porous CeO2/SnO2nanosheets with improved surface O−species and abundant oxygen vacancies exhibit superior gas sensing performance to 3‐hydroxy‐2‐butanone.

AbstractBismuth metal–organic frameworks (MOFs) as heterogeneous catalysts are scarce, and there is little knowledge on the influence of the MOF features on their resulting activity and behavior. Here, we present the synthesis, characterization, and catalytic activity in the one‐pot multicomponent Strecker reaction with ketones of three new MOFs prepared with the combination of indium or bismuth and 4,4′,4′′,4′′′‐methanetetrayltetrabenzoic acid. One of them, denoted BiPF‐7, is very robust and chemically stable, and demonstrates a high activity in the formation of the desired α‐aminonitriles. The interaction of the catalytic substrates with the metal centers in this MOF has been crystallographically characterized, showcasing a concerted framework adaptability process that involves structural changes in framework components that are not directly involved in the binding of the guests.

Published: July 2022

AbstractIt remains a formidable challenge to realize thermo‐rulable circularly polarized luminescence (CPL). Herein, we propose a new strategy by covalently “potting” the emitter into a flexible chiral macrocycle as an adaptive chiral [1]rotaxane to address this issue. Different from its included analogue, the potted emitter[DS]showed adaptive conformers with tunable CPL in varied solvents. Significantly, upon controlled self‐assembly,[DS]formed a channel‐type nanoarchitecture ([DS]A), which exhibited an extraordinary thermo‐rulable CPL between 25–100 °C. Impressively, theglumwas large as 0.024 at 25 °C, which was amplified to 0.040 at 90 °C with a decrease of QY (from 92 % to 80 %). By comparison, the assemblies of cage‐type[DS]Band the unpotted emitter showed irreversible or unanswered thermal behaviors. The work demonstrated the thermo‐rulable and durable CPL for the first time and provided an insightful understanding of thermal effect on high‐temperature and switchable CPL materials.

Published: July 2022

AbstractThe design of thermosetting materials needs to account for their environmental impact, both in the production and the end‐of‐life phases. In this study, the furan/maleimide Diels‐Alder (DA) chemistry is exploited to develop reprocessable and self‐healing networks. In particular, an epoxy monomer is first functionalized with furanic molecules obtaining DA precursors in which the diene moiety is either a pendant or a terminal group. These precursors are mixed at different relative ratios and then crosslinked with 4,4′‐bismaleimido‐diphenylmethane. The reversible nature of the formed network is investigated by thermal and dynamic‐mechanical analysis. Then the effect of the formulation, in terms of DA network architecture, on the mechanical properties and reprocessability of the resulting crosslinked materials is studied. In detail, the flexural behavior of the as‐prepared samples and reprocessed ones is evaluated, highlighting the influence of composition on the recycling efficiency.

AbstractIn the current study, the ceramifiable‐silicone‐rubber‐composites (CSRs) containing allyl‐functionalized cyclophosphazene (CP‐Allyl) were prepared for studying as novel fire‐resistant insulating materials. Electron‐beam (EB) irradiation was applied to obtain the cross‐linked networks, and the gel content of 98.8% could be achieved at an irradiation dose of 120 kGy. The thermal, mechanical, flame retardancy and insulation properties were well investigated, and it was found that the involvement of CP‐Allyl could have a great influence on the properties. The tensile stress of the EB‐irradiated CP‐Allyl containing composite reached 5.2 MPa, and its limiting oxygen index was up to 32.4%. After ablation at 700–1000°C, it was observed that the shapes of the CSR samples could be well maintained, and the hard and integrated ceramic phases were formed. All the studies indicate that these CSRs may be the promising insulating materials for wires and cables.

AbstractIn order to recycle the waste, the wasted bagasse was applied as fire‐retardant filler to prepare the waterborne intumescent fireproof coating. The effects of bagasse on the properties of the fireproof coating were investigated by fire protection test, thermogravimetric analysis, smoke suppression test, scanning electron microscope, energy dispersive spectrometer, X‐ray diffraction, Fourier transform infrared spectroscopy, water resistance test and mechanical properties test. The result demonstrated the coating with 1.5% bagasse performed best in the fire protection, thermal stability, and smoke suppression test. Moreover, the char layer of the sample after the fire protection was dense and continuous. However, the fireproof coating contained 2% bagasse had excellent performance in water resistance test and mechanical properties test due to the properties of fiber. Furthermore, the components and chemical structure of char layers were characterized to study the flame retardant mechanism of bagasse in the fireproof coating.

AbstractThis study explored the effects of hybrid nanofillers such as fumed silica (FSiO2) and reduced graphene oxide (rGO) on the mechanical, thermal, solvent transport, and tribological properties of silicone rubber nanocomposite (QMSirGO). A pin‐on‐disc test system was used to investigate the friction and wear properties of QMSirGO nanocomposites, which were significantly influenced by the applied load, temperature, and rGO concentration. Study shows that better graphene oxide dispersion in the matrix paved the way for improved tensile and dynamic mechanical properties and lowered the coefficient of friction and specific wear rate (Ws) values. Compared to silicone rubber (QM), the friction coefficient of the QMSirGO1.5 composite was reduced by around 40%. The mechanism involves the formation of a lubricant layer, which smooths the material surface that comes into contact with the metal surface. In the solvent transport study, we investigated the effect of solvents' structure, molecular size, filler concentration, and the transport mechanism of composites, and the extent of reinforcement was evaluated using Kraus equations.
Global labour, local frameworks: Timor‐Leste and Australiaʼs Seasonal Worker Programme
Authors: Rose Michael 
Published: July 2022

AbstractIn 2018–19 some 12,000 people from the Pacific and Timor‐Leste came to Australia with its Seasonal Worker Programme (SWP), part of a worldwide trend towards labour mobility. The ways in which Timorese workers use money earned individually within the SWP are shaped by broadly collectivist frameworks for understanding wealth and work embedded in their home communities. Drawing on fieldwork in Timor‐Leste and the literature on livelihood seeking and governance there, this article shows how for most Timorese in the SWP the impact of international work is mediated by local custom.
Evaluation of the benefits for mapping faint archaeological features by using an ultra‐dense ground‐penetrating‐radar antenna array
Authors: Linck Roland , Stele Andreas , Schuler Hans‐Martin 
Published: July 2022

AbstractModern archaeo‐geophysical radar surveys are often executed with multichannel antenna arrays, which allows a much faster survey progress combined with a denser profile spacing. Furthermore, from a methodological point of view, a full 3D dataset is necessary to resolve small targets of a few decimetre diameter. However, only a few test surveys deal with the evaluation of the real improvement in data quality by applying such multichannel arrays. In this paper, a test survey with the IDS Stream‐C 600‐MHz radar device on a small area covering the Roman Bath of Kempten‐Cambodunum is presented. The aim of the study is to figure out whether faint archaeological remains like hypocaust pillars, that is, the pillars of a Roman floor heating system, that are missed by single‐channel devices, are detectable in an ultra‐dense antenna array. Thus, the same area was simultaneously mapped with both GPR configurations. The results of this case study demonstrate the benefit of such antenna arrays for the archaeological prospection of small subsurface features with a diameter of 25 cm or less. For ground‐truthing of the results, a comparison with old excavation maps was executed.

Published: July 2022

AbstractThe aim of this study was the evaluation of two different procedures for the one‐pot transformation of oil extracted from Citrus limon seeds to a mixture of fatty acid methyl esters (FAMEs) and glycerol derivatives for application as a potential biofuel. Lemon seed oil was obtained by Soxhlet extraction. The first procedure was realized by efficient irreversible transesterification of the oil in hexane by lipase B from Candida antarctica (Novozym 435®) using dimethyl carbonate as the alcohol donor. For the realization of the second methodology an acid‐catalyzed transformation was carried out, dissolving the seed oil in methyl tert‐butyl ether in a microwave tube using Amberlyst®‐36 dry form catalyst. Both procedures, in optimized conditions, led to the complete conversion of the triglycerides to give the corresponding FAMEs and a mixture of glycerol derivatives. The absence of free glycerol in the final mixtures makes the two herein described procedures considerably advantageous in terms of both cost and sustainability since they enable performance of the production of FAMEs without requiring steps to remove glycerol. These final mixtures may be used in the energy chain and exploited as biofuels. © 2022 The Authors.

Published: July 2022

AbstractGreen biological manufacturing is a revolutionary industrial model utilizing yeast as a significant microbial cell factory to produce biofuels and other biochemicals. However, biotransformation efficiency is often limited owing to several stress factors resulting from environmental changes or metabolic imbalance, leading to the slow growth of cells, compromised yield, and enhanced energy consumption. These factors make biological manufacturing competitively less economical. In this regard, minimizing the stress impact on microbial cell factories and strong robust performance have been an interesting area of interest in the last few decades. In this review, we focused on revealing the stress factors and their associated mechanisms for yeast in biological manufacturing. To improve yeast tolerance, rational and irrational strategies were introduced, and the molecular basis of genome evolution in yeast was also summarized. Furthermore, strategies of genome‐directed evolution such as homology directed repair and nonhomologous end‐joining, and the synthetic chromosome recombination and modification by LoxP‐mediated evolution and their association with stress tolerance was highlighted. We hope that genome evolution provides new insights for solving the limitations of the natural phenotypes of microorganisms in industrial fermentation for the production of valuable compounds.

Published: July 2022

AbstractRegular monitoring and timely repair of concrete cracks are required to minimize further deterioration. Self‐healing of cracks has been proposed as an alternative to the crack maintenance procedures. One of the proposed techniques is to use axenic cultures to exploit microbial‐induced calcite precipitation (MICP). However, such healing agents are not cost‐effective for in situ use. As the market for bio‐based self‐healing concrete necessitates a low‐cost bio‐agent, nonaxenic sulfate reducing bacterial (SRB) granules were investigated in this study through cultivation in an upflow anaerobic sludge blanket reactor. The compact granules can protect the bacteria from adverse conditions without encapsulation. This study investigated the microbial activities of SRB granules at different temperatures, pH, and chemical oxygen demand concentrations which the microbes would experience during the concrete casting and curing process. The attenuation and recovery of microbial activities were measured before and after the exposure. Moreover, the MICP yield was also tested for a possible use in self‐healing bioconcrete. The results consistently showed that SRB granules were able to survive starvation, high temperature (50–60°C), and high pH (12), together with scanning electron microscope/energy dispersive spectrometry/X‐ray diffraction analysis evidence. Microbial staining analysis demonstrated the formation of spores in the granules during their exposure to harsh conditions. SRB granule was thus demonstrated to be a viable self‐healing nonaxenic agent for low‐cost bioconcrete.

AbstractOn‐site teaching at Ulm University was restricted in the summer semester (SS) 2020 due to the Corona pandemic. The biochemistry seminar “From gene to protein” in the 2nd preclinical semester, which had been successfully conducted as an Inverted Classroom (IC), had to be changed to an online concept. The aim of this study was to analyze the concept conversion in terms of students' satisfaction and knowledge acquisition. In the seminar, human medical students of the 2nd semester acquired biochemical and competency‐oriented learning content. In SS2019, the course was taught using the IC concept. For the conversion to the online format in the SS2020, alternative teaching materials were developed and used. Students' satisfaction was assessed by an evaluation questionnaire and knowledge acquisition was tested by a written biochemistry exam. For both teaching concepts a high level of satisfaction was detected. Individual evaluation criteria were evaluated similarly by the students for both concepts. The online concept led up to significantly higher biochemistry exam scores. Due to the high levels of students' satisfaction in both concepts and the results of the biochemistry exam, it can be concluded that online teaching offers a suitable substitute. Based on these results, it is worth to undertake further research on digitization of studies.

Published: July 2022

AbstractBackgroundThe current study examined the influence of positive “basic” emotions on executive function; there is limited evidence about the influence of positive “self‐conscious”emotions, such as pride, on executive functions processes.MethodsPride is a status‐related self‐conscious emotion and the present research explored the influence of pride on the subcomponents of executive function, using three experiments that adopted the digit size‐parity switching, N‐back, and dual choice oddball paradigms.ResultsThe behavioral results suggested that cognitive load and behavior inhibition effects in the pride emotion were significantly higher than the neutral emotion. The ERP results showed that the pride emotion elicited smaller P3 difference wave for the switching task and dual choice oddball task. In the N‐back task, the pride emotion elicited larger N1 amplitude and smaller P2 difference wave compared to the neutral emotion. A comparison among results from the three experiments indicated that pride emotion restrains all subcomponents of executive function, though with different manifestations of the impact.ConclusionExperiencing positive emotions is typically viewed as desirable and adaptive in educational settings; however, pride as a unique positive emotion may damage people's cognitive performance, indicating that we need to be cautious when performing cognitive operations in a pride mood.
