Published: October 2021

AbstractTwo series comprising 20 novel benzenesulfonamides bearing thioureido‐linked pyrazole 8 and amino‐1,2,4‐thiadiazole 10 were synthesized and assayed as human carbonic anhydrase (hCA) inhibitors against isoforms I and II as well as the tumor‐associated isoforms IX and XII. Molecular modeling studies of some potent derivatives (8a, 8c, 10a, and 10c) were also performed against isoforms hCA I, II, and XII. Both the promising series of compounds were synthesized by using commercially available mtethyl ketones and sulfanilamide as the starting materials. Interestingly, this paper also reports a novel methodology for the synthesis of amino‐1,2,4‐thiadiazoles 10 using 3‐amino isoxazoles and 4‐isothiocyanatobenzenesulfonamide as reactants. The activity profile of all the newly synthesized compounds reveals that amino‐linked 1,2,4‐thiadiazoles 10 were better inhibitors of the cytosolic isoform, hCA I, as compared to thioureido‐linked pyrazoles 8. Further, hCA II was strongly inhibited by nearly all the newly synthesized sulfonamides, while all the compounds were less effective as hCA IX and XII inhibitors compared to the standard drug acetazolamide. However, in terms of selectivity, compound 8e was found to be the most selective inhibitor of hCA II, which is the isoform associated with glaucoma, edema, altitude sickness, and epilepsy.

AbstractBackground/AimA new prototype of Solid‐State Fermentation Bioreactor, namely “Zymotis‐2 ”, was developed to produce fungal spores.Main Methods and Major ResultsA fermentation process for fungal spores, and hydrolase enzymes (endo and exoglucanases, amylases) production by Trichoderma asperellum DWG3, Aspergillus niger G131 and Beauveria bassiana was scaled‐up from flasks and glass Raimbault column packed with 20 g of solid substrates (dry weight) to 5 kg of solid substrate by using the new Zymotis‐2 bioreactor. Fungi strains growth using a mix of vine shoots, wheat bran, and olive pomace was tested under similar experimental conditions in Zymotis‐2 bioreactor, column bioreactor and flasks in a parallel fermentation system. Overall, significant spore production on Zymotis‐2 bioreactor was obtained, achieving 22.01 ± 0.01×109 spores/g DM 16.30 ± 0.07 × 109 spores/g DM, and 3.30 ± 0.07 × 109 spores/g DM for B. bassiana, T. asperellum DWG3, and A. niger G131, respectively. Forced aeration increased the endoglucanases, exoglucanases and amylases activities for T. asperellum DWG3 but B. bassiana and A. niger G131 were affected negatively by the aerated process, showing the lowest enzyme activities.Conclusions and ImplicationsIn conclusion, a high yield of spores was obtained at 137 h of cultivation time, confirming the validity of the new Zymotis‐2 bioreactor to produce virulent spores at low cost by T. asperellum, B. bassiana and A. niger G131.
Using handheld user interface and direct manipulation for architectural modeling in immersive virtual reality: An exploratory study
Authors: Tastan Hasan , Tuker Cetin , Tong Togan 
Published: October 2021

AbstractThis study comparatively investigates the affordances and constraints of two modeling methods for three‐dimensional modeling in immersive virtual reality (IVR): handheld user interface (HUI) and direct manipulation modeling (DM). The experimental study was conducted with 20 graduate students and two domain experts. Data were collected with screen capture videos of the modeling screen and video recordings of the users' gestures during the modeling session. To triangulate the findings for better reliability, an open‐ended questionnaire was administered just after the modeling session to collect written data about the modeling experience and the investigated modeling methods. Collected data were analyzed by qualitative coding methods. Analyses focused on affordances and constraints of modeling techniques, user preferences about virtual environments, effects of instant scale feature during modeling, locomotion techniques in IVR, ergonomics of the hardware related to modeling tasks, and usability of modeling interfaces in IVR. The results showed that DM modeling could be supported by (i) numeric input via a novel type of keyboard, (ii) a convenient HUI's menu interface with menu hierarchy wherever needed, and (iii) better locomotion techniques. This study generated suggestions for ensuring that efficient modeling applications for design studios, computer aided design courses, and professional practices in IVR can be implemented by investigating affordances and constraints.

Published: October 2021

AbstractViral protein R (Vpr) is an accessory protein in Human immunodeficiency virus‐1 (HIV‐1) and has been suggested as an attractive target for HIV disease treatment. Investigations of the ethanolic extracts of twelve Thai herbs revealed that the extracts of the Punica granatum fruits, the Centella asiatica aerials, the Citrus hystrix fruit peels, the Caesalpinia sappan heartwoods, the Piper betel leaves, the Alpinia galangal rhizomes, the Senna tora seeds, the Zingiber cassumunar rhizomes, the Rhinacanthus nasutus leaves, and the Plumbago indica roots exhibited the anti‐Vpr activity in HeLa cells harboring the TREx plasmid encoding full‐length Vpr (TREx‐HeLa‐Vpr cells). Moreover, the investigation of the selected main constituents in Punica granatum, Centella asiatica, A. galangal, and Caesalpinia sappan indicated that punicalagin, asiaticoside, ellagic acid, madecassic acid, madecassoside, zingerone, brazilin, and asiatic acid possessed anti‐Vpr activities at the 10 μM concentration. Among the tested extracts and compounds, the extracts from Centella asiatica and Citrus hystrix and the compounds, punicalagin and asiaticoside, showed the most potent anti‐Vpr activities without any cytotoxicity, respectively.

Published: October 2021

AbstractBackgroundImprisonment impacts on lives beyond the prisoner's. In particular, family and intimate relationships are affected. Only some countries permit private conjugal visits in prison between a prisoner and community living partner.AimsOur aim was to find evidence from published international literature on the safety, benefits or harms of such visits.MethodsA systematic literature review was conducted using broad search terms, including words like ‘private’ and ‘family’, to maximise search sensitivity but strict criteria for inclusion – of visits unobserved by prison staff and away from other prisoners. All included papers were quality assessed. Two of us independently extracted data from included papers, according to a prepared checklist. Meta‐analysis was considered.ResultsSeventeen papers were identified from 12 independent studies, all but three of them from North America. The only study of health benefits found a positive association with maintaining sexual relationships. The three before‐and‐after study of partnership qualities suggested benefit, but conjugal visiting was within a wider family‐support programme. Studies with in‐prison behaviour as a possible outcome suggest small, if any, association, although one US‐wide study found significantly fewer in‐prison sexual assaults in states allowing conjugal visiting than those not. Other studies were of prisoner, staff or partner attitudes. There is little evidence of adverse effects, although two qualitative studies raise concerns about the visiting partner's sense of institutionalisation or coercion.ConclusionsThe balance of evidence about conjugal visiting is positive, but there is little of it. As stable family relationships have, elsewhere, been associated with desistance from crime, the contribution of conjugal visiting to these should be better researched.

AbstractThe high theoretical specific capacity, strong structural designability and relatively inexpensive manufacturing cost make the exploration of organic electrode materials more attractive in recent years. In this article, owing to the large π‐conjugated structure, plenty of nitrogen heteroatoms and multiring aromatic system, polyazaacene analogue poly(1,6‐dihydropyrazino[2,3 g]quinoxaline‐2,3,8‐triyl‐7‐(2H)‐ylidene‐7,8‐dimethylidene) (PQL) was applied as the anode in sodium‐ion batteries (SIBs). PQL was almost insoluble in conventional liquid organic electrolyte (1 M NaClO4 in ethylene carbonate (EC)/dimethyl carbonate (DMC) (v:v=1 : 1) with 5 % fluoroethylene carbonate (FEC)), which strongly improved its cycle stability. The initial discharge capacity was obtained to be 1825 mAh g−1 at the current density of 100 mA g−1 and stabilized at 317 mAh g−1 after 400 cycles with the coulombic efficiency as high as 97 %. It not only showed good rate capability at high current densities (202, 183 mAh g−1 at 1 A g−1 and 1.5 A g−1) but also had a superior energy density around 290 Wh kg−1.

BackgroundGathering information directly from cancer survivors has advanced our understanding of the cancer survivorship experience. However, it is unknown whether surveys can distinguish important subgroups of cancer survivors. This study aimed to describe the current landscape of survey questions used to identify and describe cancer survivors in national cross‐sectional studies.MethodsUsing publicly available databases, the authors identified national cross‐sectional surveys used in the United States within the past 15 years that included a question on self‐reported history of cancer. After abstracting questions and response items used to identify cancer survivors, they conducted a descriptive analysis.ResultsThe authors identified 14 national cross‐sectional surveys, with half administered to the general population and the other half administered to cancer survivors. The most common question used to identify cancer survivors was “Have you ever been told by a doctor or other health professional that you had cancer?” Most surveys had questions asking participants to identify a single cancer type (n = 11), multiple prior cancer diagnoses or types (n = 11), and the time from diagnosis (n = 12). Treatment questions varied from active treatment status to specific treatments received. Questions addressing cancer stage (n = 2), subtypes (n = 1), metastatic status (n = 3), and recurrence (n = 4) were less frequently included.ConclusionsThere is no standard method for assessing self‐reported cancer history, and this limits the ability to distinguish among potentially important subgroups of survivors. Future cross‐sectional surveys that capture nuanced data elements, such as cancer types, stages/subtypes, metastatic/recurrent status, and treatments received, can help to fill important gaps in cancer survivorship research and clinical care.
Impact of physical decontamination methods on zirconia implant surface and subsequent bacterial adhesion: An in‐vitro study
Authors: Tan Nathan Chiang Ping , Miller Catherine M. , Antunes Elsa , Sharma Dileep 
Published: October 2021

AbstractObjectiveTo evaluate the effect of routinely used physical decontamination methods on the surface characteristics of zirconia implants and subsequent ability of bacteria to adhere in vitro.BackgroundPhysical decontamination methods commonly used in peri‐implantitis therapy and routine implant maintenance can potentially alter zirconia implant surfaces.MethodsAcid‐etched zirconia discs were instrumented with titanium curette (TC), plastic curette, air abrasive device, ultrasonic scaler (US) with stainless steel tip. Following instrumentation, surface topography, and surface elemental composition was analyzed using 3D‐laser scanning microscopy and energy‐dispersive X‐ray spectroscopy, respectively. Subsequently, plaque biofilm was cultured on zirconia discs for 48 h and bacterial adhesion assessed using a turbidity test and scanning electron microscopy.ResultsA significant difference in surface roughness was observed between the US and control group (p < 0.05). The US and TC caused gray surface discolouration on zirconia discs due to deposition of metallic residue as confirmed by X‐ray spectroscopy. No significant difference in bacterial adhesion was noted among all treatment groups (p > 0.05).ConclusionTC and US with stainless steel tips should be used with caution due to deposition of metallic residue on the surface. Air abrasive devices and plastic curettes caused minimal surface alterations and are, therefore, safer for zirconia implant decontamination.
Shaping sustainable development: External environmental pressure, exploratory green learning, and radical green innovation
Authors: Cui Rixiao , Wang Juanru 
Published: October 2021

AbstractAlthough external environmental pressure has been recognized as an important driver of green innovation, the literature ignores its effect on radical green innovation. Combining theories of organizational learning and transformational leadership, this study explores the relationships among external environmental pressure, exploratory green learning, and radical green innovation, and analyzes the moderating role of green transformational leadership. Considering the political and economic factors in social network, this study focuses on the pressures of environmental regulatory and green market. Data are collected from 282 manufacturing firms in China's strategic emerging industries, hierarchical regression analysis and boostrapping are used to test hypotheses. The results reveal that environmental regulatory pressure and green market pressure have positive effects on exploratory green learning, and exploratory green learning has positive effects on radical green innovation. Exploratory green learning plays a full mediating role in the relationship between environmental regulatory pressure and radical green innovation, and partially mediates the relationship between green market pressure and radical green innovation. Moreover, green transformational leadership has a nonlinear moderating effect on the relationship between exploratory green learning and radical green innovation. This study opens avenues for understanding the relationship between external environmental pressure and raidcal green innovation, which enriches the literature on green innovation and offers practical implications for government and firms.

Published: October 2021

AbstractA family of six terbium(III) complexes with hexaaza macrocyclic ligands, together with the isostructural yttrium(III) species, is reported and the thermal dependence of the photophysical properties of the terbium(III) complexes is analysed. The coordination number is defined by the anions, nitrate or isothiocyanate, which act as secondary ligands. While complexes with nitrate anions are decacoordinated species, presenting a N6O4 first coordination sphere, complexes derived from isothiocyanate are nonacoordinated with exclusively nitrogen donor atoms. Regarding the optical properties, only the macrocyclic ligands derived from aliphatic amines act as sensitizers for the terbium(III) cations, and the complexes emit in the green region, according to the obtained CIE coordinates. The isothiocyanato ligand plays a detrimental role on the luminescence of the corresponding complexes, since their emission is weaker as compared to that of the nitrato counterparts. The greater achieved thermal sensitivity for one of the studied terbium(III) complexes was 3.2 %K−1 at 300 K.
Exhaustive One‐Step Bridgehead Methylation of Adamantane Derivatives with Tetramethylsilane
Authors: Bonsir Maxime , Davila Christian , Kennedy Alan R. , Geerts Yves 
Published: October 2021

AbstractA methylation protocol of adamantane derivatives was investigated and optimized using AlCl3 and tetramethylsilane as the methylation agent. Substrates underwent exhaustive methylation of all available bridgehead positions with yields ranging from 62 to 86 %, and up to six methyl groups introduced in one step. Scaling‐up of the reaction was demonstrated by performing the >40 gram‐scale synthesis of 1,3,5,7‐tetramethyladamantane with 62 % yield. For several substrates, rearrangements were observed, as well as cleavage of functional groups or Csp3−Csp2 bonds or even cyclohexyl‐adamantyl bonds. Based on mechanistic studies, it is suggested that a reactive methylation complex is formed from tetramethylsilane and AlCl3. X‐ray diffraction structures of hexamethylated bis‐adamantyls reveal elongation or widening of sp3 carbon bonds between adamantyl moieties to 1.585(3) Å and 125.26(9)° due to repulsive H⋅⋅⋅H contacts.
Sentiment‐dependent impact of funding liquidity shocks on futures market liquidity
Authors: Ryu Doojin , Yu Jinyoung 
Published: October 2021

AbstractWe examine the effect of funding liquidity changes on futures market liquidity, depending on economic sentiment. Futures market liquidity improves following negative funding liquidity shocks, and economic sentiment is an important determinant explaining this relationship. While individuals' trading is most significantly affected by sentiment, its response to funding liquidity shocks remains independent of sentiment effects. Domestic institutions' reactions depend on the sentiment regime; they trade futures contracts more actively as funding liquidity becomes more abundant (scarcer) when sentiment is more pessimistic (optimistic). Foreigners, following negative funding liquidity shocks, generally increase their futures trading, whereas their trading decreases under the extremely pessimistic sentiment. Domestic banks and pension funds provide liquidity to the futures market even when sentiment is pessimistic.
Feeder 9 Gas Pipeline Replacement Tunnel – Achieving a world record for pipe insertion of a new gas pipeline within a tunnel beneath the river Humber (UK)
Authors: Jukes Simon , Schenk Stephan 
Published: October 2021

AbstractSince December 2020, at a pressure of 70 bar, up to 25 % of Britain's gas requirements was flowing through the new Feeder 9 gas pipeline, which installed in a 4.9 km long tunnel 30 m below the River Humber. With the insertion of the new pipeline, the Humber Pipeline Joint Venture (HPT JV), consisting of the companies Porr, Skanska and A. Hak, achieved a major milestone when it was officially recognised as a Guinness World Record for the longest hydraulically‐inserted pipe at 4,963.7 m long. Replacing the existing pipeline was an absolute necessity due to the shifting river bed which, over the years, had exposed sections of the pipeline threatening the supply to the customers in the UK. The solution adopted by the client, National Grid to provide a long‐term permanent solution, was for the construction of a segmental lined tunnel with an inner diameter of 3.65 m accommodating the new 1050 mm diameter welded steel gas pipe. The tunnel was excavated with a 4.4 m diameter mix shield type TBM. The small diameter together with the length, without intermediate access including a tidal range in the Humber estuary of up to 6.4 m and an overburden on the tunnel of 10 m below the river bed resulted in a number of challenges. The installation of the concrete‐coated steel pipeline was particularly high risk. The individual strings ranging from 595 to 620 m in length and weighing about 850 t, were pushed consecutively into the water‐filled tunnel employing two hydraulic thrusters in just 18 days.
Erkennen geotechnischer Vorgänge an der Ortsbrust als Schlüssel zum erfolgreichen Tunnelvortrieb
Authors: Steiner Walter 
Published: October 2021

AbstractWhen tunnelling with a TBM (Tunnel Boring Machine) in rock and soil, mostly the machine is described and often reduced to a slogan. Such descriptions say little about geotechnical processes at the tunnel face that are key to the success of tunnel driving and must be considered when selecting a tunnelling system. In soil tunnels the tunnel face must be safely supported and extracting material must be possible. For a slurry shield the slurry must not escape and pressure must act on the face. In the literature mostly bentonite content is considered. With an Earth‐Pressure balance machine the soil has to have characteristics that it can be remoulded and transformed in a mass of adequate consistency with mechanical means, adding water and additives such that this mass can support the face and be extracted. Long‐term experience shows that the fine content and polymers are also important factors. Flow channels (pores) in open gravel may be clogged, and the face supported by seepage forces. Also, the drag forces in the slurry circuit are increased and the operation of the slurry circuit became more stable. Rates of advance exceeding 10 m/day were achieved with a 11.6 m slurry shield. The limited depth of penetration of the slurry could be determined in‐situ. For fine‐grained soils the characteristics of the fines are crucial and are described by the Atterberg limits. Soil mechanics strength properties may be vastly different.
Linienkreuz U2xU5 – Tunnelbaumaßnahmen am Bauabschnitt U2/22
Authors: Suchmann Christoph , Fuchs Christian 
Published: October 2021

AbstractThe next expansion phase of the U2xU5 intersection is currently under construction in the inner districts of the City of Vienna. The construction lot U2/22 Rathaus (City Hall) takes place in the inner districts 1, 7 and 8. Three shafts are the main focus of the construction works at Friedrich‐Schmidt‐Platz, directly behind the Vienna City Hall as well as a shaft with extensive works on the building of the University of Vienna and another shaft at Josefstädter Straße. Due to difficult and changing geology, different support measures from full face tunnel excavation to tunnelling under a roof of jet grouting piles will be used. In addition, measures such as groundwater drainage, structural improvements of buildings and settlement compensations are necessary in advance.
