Integrated BIM‐to‐FEM approach in mechanised tunnelling
Authors: Alsahly Abdullah , Hegemann Felix , König Markus , Meschke Günther 
Published: April 2020

AbstractIn current tunnelling practice, Finite Element (FE) simulations form an integral element in the planning and the design phase of mechanised tunnelling projects. The generation of adequate computational models is often time consuming and requires data from many different sources, in particular, when manually generated using 2D‐CAD drawings. Incorporating Building Information Modelling (BIM) concepts offers opportunities to simplify this process by using geometrical BIM sub‐models as a basis for structural analyses. This paper presents a Tunnel Information Model (TIM) as a BIM specifically tailored to fit the needs of mechanised tunnelling projects and a ”BIM‐to‐FEM“ technology, that automatically extracts relevant information (geology, alignment, lining, material and process parameters) needed for FE simulations from BIM sub‐models and subsequently performs FE analysis of the tunnel drive. The results of the analysis are stored centrally on a data server to which the user has continuous access. A case study from the Wehrhahn‐Metro line project in Düsseldorf, Germany, is presented and discussed to demonstrate the efficiency and the applicability of the proposed BIM‐to‐FEM workflow.
Structured review of the use of the Arizona sexual experiences scale in clinical settings
Authors: Elnazer Hesham Y , Baldwin David S 
Published: April 2020

AbstractBackgroundApproximately 40% of women and 30% of men describe sexual dysfunction, although recognition in medical settings is suboptimal, due to problems in reporting and eliciting concerns relating to sexual function and satisfaction. Screening questionnaires may help to support this aspect of clinical practice. The Arizona sexual experiences scale (ASEX) includes items that quantify sex drive, arousal, vaginal lubrication or penile erection, ability to reach orgasm, and satisfaction from orgasm.MethodWe investigated the validity and other psychometric properties of the ASEX, and the findings from the populations in which it has been employed, by searching MEDLINE, EMBASE, and Google Scholar using the terms, Arizona sexual experiences scale, Arizona Sexual Experience Questionnaire, and ASEX. We eliminated duplications, letters, and papers not available in English, and grouped the remaining papers into the categories of psychometric, epidemiological, and outcome‐based studies.ResultsAfter elimination of letters and duplicates, papers not in English, and preclinical and irrelevant studies, 104 papers were analyzed. The ASEX has excellent internal consistency, scale reliability and strong test–retest reliability. Analyses of variance reveal significant differences in total ASEX scores between patients and controls and between females and males. ASEX appears to be useful in a range of clinical situations including patients with primary sexual dysfunction, specific psychiatric disorders, specific physical illnesses, and treatment emergent sexual dysfunction.DiscussionThe ASEX appears to be a reliable instrument for identifying and quantifying sexual dysfunction across a range of populations in various clinical settings. Little is known about its utility in patients with anxiety disorders or relationships between ASEX scores and biological parameters.
Sustainable management of water in northern California, USA, for food, energy, and environmental security*
Authors: Roche Walter Martin 
Published: April 2020

AbstractSustainable management of water for food security, municipal and industrial use, energy, and the environment is important in the twenty‐first century. In northern California, USA, surface and groundwater resources are generally adequate in most years to meet all needs and to provide water to other areas of California where water demand usually exceeds local supplies.The average annual runoff in the Sacramento River basin in northern California is over 27 billion cubic metres (22 million acre‐feet) per year, over one‐third of the total runoff in all of California.In 2014 California adopted the Sustainable Groundwater Management Act, which resulted from growing concern throughout the state about the overuse of groundwater. In northern California most of the groundwater basins are already sustainable, with the opportunity to provide much needed water to other areas of California where sustainability will be difficult to achieve.One of the major food crops raised in the area is rice. Of the approximately 243 000 ha (600 000 acres) of rice production in California, 95% are in northern California.Energy sustainability is also important in California and throughout the world. California has set a goal of meeting all energy demands from renewable resources by 2045.

Published: April 2020

AbstractAimsAims included (a) characterizing provider feedback on parent engagement strategies integrated into a parent‐mediated intervention for toddlers at risk for autism spectrum disorder (ASD) and (b) identifying provider characteristics that predict attitudes about parent engagement strategies.MethodsA mixed method approach was utilized, including gathering quantitative data via survey (breadth) and collecting qualitative data via interview (depth). Acceptability, utility, appropriateness, sustainment, generalizability, and perceived effectiveness were examined. Fourteen agency leaders and 24 therapists provided input.ResultsProviders perceived the integration of parent engagement strategies as having a positive impact on implementation. Providers considered the strategies to be acceptable, appropriate, and effective, though barriers of time and complexity were noted. Provider characteristics did not consistently predict attitudes about the engagement strategies.ConclusionsIncorporating parent engagement strategies into parent‐mediated interventions for ASD is well‐received by providers and may improve quality of service delivery for families served in early intervention for ASD.
Influence of surface design on performance of MnO‐decorated nanocatalyst for olefin production from methanol: ZSM‐5@MnO core–shellversusMnO/ZSM‐5 dispersed nanocatalysts
Authors: Khaledi Kharazm , Haghighi Mohammad , Sadeghpour Parisa 
Published: April 2020

AbstractBACKGROUNDIn the assembly of nanoparticles (NPs) onto zeolites, the surface design of NPs has a great influence on various catalytic properties. Herein, ZSM‐5 was hydrothermally synthesized and its external surface was decorated by MnO NPs in two different surface designs: distributed MnO NPs and MnO shell.RESULTSThe synthesized MnO‐decorated samples, MnO/ZSM‐5 and ZSM‐5@MnO, were analyzed using various techniques. The results of these analyses reveal the formation of desired crystal phases without any impurities and confirm the perfect assembly of uniform MnO NPs on the surface of ZSM‐5. Also, it was found that the surface design of MnO NPs has a great impact on the physicochemical properties of the nanocatalyst. Basically, ZSM‐5 is highly selective toward propylene, but the shape selectivity of MnO NPs increases the selectivity of MnO‐decorated nanocatalysts toward ethylene. Moreover, this study delves deeply into differences in catalytic behaviors of the nanocatalysts during the methanol‐to‐olefin process and explains how they are attributed to the applied surface designs.CONCLUSIONSThe catalytic performance studies at optimum temperature show that the ZSM‐5@MnO nanocatalyst is more selective toward ethylene, and it has a nearly 20% higher methanol conversion rate compared to the MnO/ZSM‐5 nanostructured catalyst. Due to the surface acidity adjustment of MnO shell as well as high control of core–shell structure over the location of coke formation, the ZSM‐5@MnO nanocatalyst shows longer stability and its activity remains constant with time on stream. © 2020 Society of Chemical Industry

AbstractCoronavirus disease 2019 (COVID‐19) broke out in Wuhan, Hubei, China in December 2019. Tens thousands of people have been infected with the disease. Our aim was to distinguish severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)‐positive patients from SARS‐CoV‐2‐negative patients. We retrospectively compared the data of COVID‐19 patients with those of suspected and confirmed SARS‐CoV‐2‐negative patients (control patients). There were 78 COVID‐19 patients and 26 control patients, whose median ages were significantly different (P = .001). The percentage of COVID‐19 patients admitting exposure to Wuhan was obviously higher than that of control patients (X2 = 29.130; P < .001). Fever and cough appeared more frequently in COVID‐19 patients than in the control patients. The routine blood workup parameters of COVID‐19 patients did not change much and their mean counts were in the normal range. There were 38.5% of control patients had higher procalcitonin (PCT) levels than 0.5 ng/mL, which was significantly higher than that percentage of COVID‐19 patients (X2 = 22.636; P < .05), and COVID‐19 patients were also more likely to have decreased or normal urea and creatinine levels than control patients (X2 = 24.930, 8.480; P < .05).Younger age, exposure to Wuhan, fever, cough, and slight changes in routine blood workup parameters, urea and creatinine were important features discriminating COVID‐19 from control patients. Slightly increased, but far less than 0.5 ng/mL, PCT levels also differentiated COVID‐19 patients from control patients.

Published: April 2020

AbstractCOVID‐19 is a pandemic that began in China in December 2019. World health organization (WHO) has expressed fears that Pakistan might emerge as the next epicenter of this pandemic. We hypothesize that at present the Pakistani masses are not prepared to face any threat of a looming epidemic. The main aim of this study was to evaluate the basic knowledge of educational and health care workers (HCWs) regarding COVID‐19, its control, and prevention. Knowledge about origin, symptoms, and spread of viral infection was assessed. In this cross‐sectional survey, a self‐designed questionnaire was distributed among 302 HCWs including physicians (10.9%), nurses (1.32%), lab staff (1.65%), and academic individuals including faculty and students (86.42%) of different organizations. Results were analyzed using the χ2 test. Obtained results validate our null hypothesis that Pakistani masses are not well aware of the COVID‐19 and strategies for the prevention and control of infection. The study concluded that individuals belonging to the front‐line workers and high literacy groups are not prepared for the alarming situation in the country. Effectual implementation of infection control programs should be practiced, and it depends on awareness, training, and cooperation of individuals.
Short Communication. Quantification of loess proportions in Pleistocene periglacial slope deposits and Holocene colluvium using grain‐size data by laser diffractometry
Authors: Yang Fei , Karius Volker , Sauer Daniela 
Published: April 2020

AbstractLoess proportions in slope deposits have rarely been quantified, due to the lack of quantification methods. In this study, we used laser granulometry to analyze grain‐size distributions in slope deposits of a Buntsandstein landscape in central Germany. The consistent loess contents obtained from two independent models corroborate the validity of the calculated loess proportions and the applicability of the new R package EMMAgeo. Yet, some limitations in transferability need to be considered.
Destination loyalty explained through place attachment, destination familiarity and destination image
Authors: Stylidis Dimitrios , Woosnam Kyle M. , Ivkov Milan , Kim Seongseop S. 
Published: April 2020

AbstractThis study explores how familiarity and attachment, along with cognitive and affective image explain destination loyalty across visitors with divergent degrees of frequency of visitation (low vs. high). Serbians (n= 401) who have previously visited Greece comprised the sample population for this study and were surveyed using a self‐administered questionnaire. Findings reveal that overall familiarity shapes cognitive and affective destination image, while each image component uniquely explains destination loyalty (R2= 0.51). Differences also exist in the magnitude of the relationships tested among the two groups. Implications for theory and practice, along with limitations and research directions, are discussed.

Published: April 2020

AbstractMethicillin‐resistant S. aureus has been reported as the main pathogen involved in chronic infections, osteomyelitis, and prosthetic joint infections. The host/pathogen interaction is dynamic and requires several changes to promote bacterial survival. Here, we focused on the internalization and persistence behavior of well‐characterized Staphylococcus aureus invasive strains belonging to the main ST‐MRSA‐SCCmec clones. To overcome the limitations of the cell culture method, we comparatively analyzed the ability of internalization within human MG‐63 osteoblasts with imaging flow cytometry (IFC). After evaluation by cell culture assay, the MRSA clones in the study were all able to readily internalize at 3h postinfection, the persistence of intracellular bacteria was evaluated at 24h both by routine cell culture and IFC assay, after vancomycin‐BODIPY staining. A statistical difference of persistence was found in ST5‐SCCmecII (26.59%), ST228‐SCCmecI (20.25%), ST8‐SCCmecIV (19.52%), ST239‐SCCmecIII (47.82%), and ST22‐SCCmecIVh (50.55%) showing the same ability to internalize as ATCC12598 (51%), the invasive isolate used as control strain for invasion and persistence assays. We demonstrated that the intracellular persistence process depends on the total number of infected cells. Comparing our data obtained by IFC with those of the cell culture assay, we obtained greater reproducibility rates and a number of intracellular bacteria, with the advantage of analyzing live host cells. Moreover, with some limitations related to the lack of whole‐genome sequencing analysis, we validated the different proclivities to persist in the main Italian HA‐MRSA invasive isolates and our results highlighted the heterogeneity of the different clones to persist during cell infection.

AbstractThis article presents the synthesizing of nickel ferrite by sol‐gel modified ionic coordination reaction technique with application in millimetric wave Ferrite Powder Resonator Antenna device fed by a coaxial probe. The ferrite powder was morphologically characterized by X‐rays diffraction, energy dispersive X‐Ray spectrometer, and scanning electron microscopic image; hysteresis loop was also obtained to analyze static magnetic field application and powder's electrical characterization was performed. Ferrite powder electric characterization displayed consistent data, including a material resonance phenomenon around 7.4 GHz. The ferrite powder resonator antenna was designed according to IEEE 802.11a/n protocol and, at resonance frequency around 2.8 GHz, the reflection coefficient results presented a noninfluence of wood material in antenna response, along with a good agreement between experimental and simulated results, reaching a maximum relative error of 1.82%, indicating a promising application of ferrite powder as a resonator.
Functional Systems Derived from Nucleobase Self‐assembly
Authors: del Prado Anselmo , González‐Rodríguez David , Wu Yi‐Lin 
Published: April 2020

AbstractDynamic and reversible non‐covalent interactions endow synthetic systems and materials with smart adaptive functions that allow them to response to diverse stimuli, interact with external agents, or repair structural defects. Inspired by the outstanding performance and selectivity of DNA in living systems, scientists are increasingly employing Watson−Crick nucleobase pairing to control the structure and properties of self‐assembled materials. Two sets of complementary purine‐pyrimidine pairs (guanine:cytosine and adenine:thymine(uracil)) are available that provide selective and directional H‐bonding interactions, present multiple metal‐coordination sites, and exhibit rich redox chemistry. In this review, we highlight several recent examples that profit from these features and employ nucleobase interactions in functional systems and materials, covering the fields of energy/electron transfer, charge transport, adaptive nanoparticles, porous materials, macromolecule self‐assembly, or polymeric materials with adhesive or self‐healing ability.
Catalytic Activity Towards Hydrogen Evolution Dependent of the Degree of Conjugation and Absorption of Six Organic Chromophores
Authors: Aleksovska Angela , Lönnecke Peter , Addicoat Matthew A. , Gläser Roger , Hey‐Hawkins Evamarie 
Published: April 2020

AbstractConjugated materials can, in many cases, absorb visible light because of their delocalized π electron system. Such materials have been widely used as a photoactive layers in organic photovoltaic devices and as photosensitizers in dye‐sensitized solar cells. Additionally, these materials have been reported for applications in solar fuel production, working as photocatalysts for the hydrogen evolution reaction (HER). The synthesis of three flexible vinyl groups‐containing chromophores is reported. The catalytic activity towards hydrogen evolution of these chromophores has been investigated and compared to their non‐vinyl‐containing analogues. The catalytic effect was confirmed using two different approaches: electrochemical, using the chromophores to modify a working electrode, and photocatalytic, using the chromophores combined with platinum nanoparticles. A relationship between the degree of conjugation and the catalytic activity of the chromophores has been observed with the electrochemical method, while a relationship between the UV absorption in the solid state and the photocatalytic effect with platinum nanoparticles was observed.

AbstractThe chemical recycling of end‐of‐life polymers can add some value to a future circular economy. In this regard, the hydrogenative degradation of end‐of‐life PLA was investigated to produce 1,2‐propanediol as product, which is a useful building block in polymer chemistry. In more detail, the commercially available Ru‐MACHO‐BH complex was applied as catalyst to degrade end‐of‐life PLA efficiently to 1,2‐propanediol under mild conditions. After investigations of the reaction conditions a set of end‐of‐life PLA goods were subjected to degradation.

AbstractBackgroundWhile lung transplantation (LTx) improves health‐related quality of life (HRQL) in cystic fibrosis (CF), the determinants of this improvement are unknown. In other populations, frailty—a syndrome of vulnerability to physiologic stressors—is associated with disability and poor HRQL. We hypothesized that improvements in frailty would be associated with improved disability and HRQL in adults with CF undergoing LTx.MethodsIn a single‐center prospective cohort study from 2010 to 2017, assessments of frailty, disability, and HRQL were performed before and at 3‐ and 6‐months after LTx. We assessed frailty by the short physical performance battery (SPPB). We assessed disability with the Lung Transplant Valued Life Activities scale (LT‐VLA) and HRQL by the Medical Outcomes Study Short Form Physical and Mental Component Summary scales (SF12‐PCS, ‐MCS), the Airway Questionnaire 20‐Revised (AQ20R), and the Euroqol 5D (EQ5D). We tested the association of concurrent changes in frailty and lung function on disability and HRQL by linear mixed‐effects models adjusted for sex and body mass index.ResultsAmong 23 participants with CF, improvements in frailty and lung function were independently associated with improved disability and some HRQL measures. For example, each 1‐point improvement in SPPB or 200 mL improvement in FEV1 was associated with improved LT‐VLA disability by 0.14 (95%CI: 0.08‐0.20) and 0.07 (95%CI: 0.05‐0.09) points and improved EQ5D by 0.05 (95%CI: 0.03 to 0.07) and 0.02 (95%CI: 0.01‐0.03) points, respectively.ConclusionImprovement in frailty is a novel determinant of improved disability and HRQL in adults with CF undergoing LTx.
