Investigation of flexible warp-knitted metal meshes for electromagnetic interference shielding

This paper develops four novel warp-knitted structures with two bars of the one-in one-out threading mode and describes the investigation of electromagnetic interference (EMI) shielding metal meshes composed of contiguous ultra-fine metal wires fabricated using warp-knitting technology. The mechanical properties, electrical conductivity, and microwave shielding effectiveness (SE) of the flexible meshes are assessed in terms of the mesh structure, mesh material, and warp run-in parameter. The results reveal that the metal mesh has a flexible and stable mechanical property, good electrical conductivity, and optimal EMI performance when the mesh structure is open lap atlas. The gold-coated molybdenum mesh exhibits the lowest electrical resistivity (5.18 × 10−5 ohm/sq) and optimal average EMI SE (–21.04 dB), making it a candidate for EMI shields for intelligent wearable electronic devices. The warp run-in can adjust the EMI SE, and the optimum average EMI SE (–25.52 dB) can be obtained when the warp run-in is set at the 2580 rack. Moreover, the warp-knitted metal meshes show desirable EMI shielding efficiency persisting at >70% even at large strain deformations and under cyclic bending and twisting deformations. Conductive warp-knitted meshes with a millimeter period and micron-scale wire diameter exhibit an adequately large scale, satisfactory mechanical stability, excellent flexibility, permanent conductivity, and strong microwave reflection, simultaneously. Moreover, the EMI SE of warp-knitted metal mesh reaches the protection level (–20 dB) prescribed by standard electronic devices. Therefore, the warp-knitted metal meshes show great potential in flexible and wearable EMI shielding devices.
Electrical Life of Vacuum Interrupters for Load Current Switching

While the short-circuit current of vacuum interrupters (VIs) is a key performance parameter, very high current operations rarely occur in actual applications. In contrast, switching load and/or capacitive currents comprise virtually all the practical operations. Load current switching requires a low contact erosion and low metal vapor generation of the arc to achieve a long electrical life and is achieved by contacts in vacuum. However, the excellent performance of contacts in vacuum makes the testing and determination of the ultimate electrical life at load currents challenging. Tests on Cu–Cr and Cu–W contacts in VIs were performed at 2500–2700 A rms with 20 000–30 000 switching operations. The VIs with both types of contacts retained their dielectric strength, contact shape and composition, and low contact resistance. Even after arcing operations with total transferred charges >200 kA $\cdot $ s per interrupter, the contacts could continue providing good dielectric and switching performance with low resistance. Contact erosion was minimal and of limited practical significance. These results demonstrate the very long electrical life of VIs when the vacuum arc is naturally diffuse.
Touring ‘post conflict’ Belfast

The purpose of this paper is to explore Belfast as a site of ‘dark tourism’ through a case study of Coiste which is a tour company based in West Belfast which employs former political prisoners as tour guides. These tours advertise themselves as providing an ‘authentic’ account of ‘the troubles’ through a broad republican lens. This outlook frames the narrative within which the history of Belfast is discussed by those who are considered as former ‘terrorists’ who draw on their lived experiences of taking part in violent conflict. While the example may seem as an unlikely contender for the role that tourism can play in peace transformation processes, nonetheless, the discourses on offer provide a necessary addition to mainstream tourism products which often involve sanitising the past and airbrushing history by turning it into an uncontentious, consumable tourist commodity. The paper is based on ‘walk and talk’ interviews with tour guides and Tripadvisor Reviews of these tours.
Synthesis and Characterization of BiOI Films for Photo-Electrochemical Cell via Simple Heating Process of BiI3

This work aims to prepare BiOI films via simple heating of BiI3 materials and study their characters from structural, optical, and morphology perspectives. In the heating process, we varied the heating treatment time. In addition, the solar cell performance of prepared BiOI films was tested. In BiOI preparation, we deposited BiI3 films first onto FTO substrates via BiI3 heating in the air using a closed chamber at the temperature of 360 °C for 30, 45, and 120 minutes. The deposited BiI3 films were then rinsed with water/ethanol and re-heated at 350 °C for 30 minutes. As a result, by increasing the heating treatment time, it could form thicker BiOI films. All the resulting films confirmed the BiOI characters. A longer BiI3 heating time could direct the growth of BiOI crystal, wavelength red-shift, and flake structure. In the electrochemical solar cell study, it was known that BiOI films had a lower performance compared to the reported results. After a certain thickness (~1.3 μm), the device's open-circuit voltage and current decreased.
Slow propagation line-based superconducting devices for quantum technology

In the field of circuit quantum electrodynamics (c-QED), the coherent interaction of two-level systems (TLSs) with photons, confined in a superconducting microwave resonator, opens up new possibilities for quantum computing experiments. This thesis contributes to the expansion of c-QED tool-box with slow propagation line-based solutions for ubiquitous techniques, such as cryogenic Near Field Scanning Microwave Microscopy (NSMM), Electron Spin Resonance (ESR) spectroscopy and Traveling Wave Parametric Amplifier (TWPA). For NSMM, novel compact superconducting fractal resonators have been developed to be directly integrated on a scanning probe. We report NSMM operation based on a microwave high-Q resonator populated with less than 10^3 photons and demonstrate a capacitive sensitivity of 0.38 aF/rtHz. The unique properties and the design flexibility of fractal resonators also boost their resiliency to strong magnetic fields for ESR studies. The reported high Q-factors above 10^5 in a magnetic field up to 0.4 T translate into ESR sensitivity of 5 10^5 spins/rtHz. Furthermore, we demonstrate the operation of a practical TWPA based on a slow propagation fractal line. We achieve per unit length gain of > 0.5 dB/cm and total gain of ~6 dB for a 10 cm long line. Due to a radically shortened line, the amplifier is less vulnerable to fabrication defects. Moreover, due to a successful impedance matching between the amplifier line and in/out terminals, the obtained gain vs frequency characteristic has only moderate ripples. To mitigate a common TWPA problem of coupling to parasitic ground plane resonances, we deploy a novel multilayer fabrication technology, which combines high and low kinetic inductance (KI) elements. Finally, we present an alternative implementation of a slow propagation line: a microstrip line with a thin film Atomic Layer Deposition (ALD) Al2O3 oxide. The resonator, based on a segment of a microstrip line, has a Q-factor on the order of 10^4 at single photon powers, reaching up to 10^5 at higher powers. As an additional functionality, we incorporate dc current control over KI so that the resonance frequency is tuned by 62 MHz range, which corresponds to a KI-related nonlinearity of 3%.
Estimation of genetic parameters of Wood’s lactation curve parameters using Bayesian and REML methods for milk production trait of Holstein dairy cattle

ABSTRACT Bayesian and average information restricted maximum likelihood (AI-REML) approaches were used to estimate variance components and genetic parameters of Wood’s lactation curve parameters of milk production traits in three lactations of Iranian Holstein dairy cows. Wood’s function parameters (a, b, and c) of each lactation were initially estimated for individual cows using the NLIN procedure of the SAS programme, separately. The variance components of the parameters of each lactation were estimated by the AI-REML method using a single-trait animal model inairemlf90 programme. To do this with the Bayesian method by using the Gibbs sampling technique, the same animal model was used in the gibbs3f90 programme. The estimated heritability values by the AI-REML were 0.018, 0.00, and 0.019 for a parameter; 0.015, 0.007, and 0.02 for b parameter; and 0.23, 0.625, and 0.049 for c parameter in the 1st, 2nd, and 3rd lactations, respectively. The corresponding results from the Bayesian procedure (a posterior means) were 0.019, 0.01, and 0.035 for a parameter; 0.018, 0.019, and 0.043 for b parameter; and 0.024, 0.1, and 0.058 for c parameter, respectively. These obtained results reveal that the differences between the Bayesian and AI-REML methods in terms of estimation of heritability and variance components were small.
STABILITY OF STRIP FOOTING ON SAND BED WITH CIRCULAR VOID

Underground voids can be created by different reasons such as tunneling, mining, water and gas networks and old conduits. These voids can cause serious engineering problem leading to instability of the foundation, incurring severe damage to the superstructure. With population growth and resulting extension of urban sprawl to the areas of prior mining cavity such as new cities in Egypt (Menia new city, Assuit new city, Sohag new city and et.,) there is a growth concerning to the geotechnical engineering regarding the foundation stability in these areas. In this paper, numerical investigation of such phenomenon is presented using PLAXIS, 2D software. A series of numerical analysis for strip footing supported on sand bed with an inside circular continuous voids were carried out. The parameters studied in this investigation include the relative density of sand bed (dense sand, medium dense sand and loose sand), the voids embedment depth and voids diameter. The results demonstrate that the bearing capacity of strip footing decreases with the decrease of void embedment depth and vice versa. Also, the bearing capacity decreases with the increase of void diameter. For all sand relative densities, the undesirable structural effects of the void can be eliminated for a void embedded at a depth of around 3.5 times the void's diameter (D). An Equation relating the bearing capacity ratio with the influencing factors investigated is developed. This equation provides a data base useful for design of continuous footing centered with an underground void.
Second language reading and recall processes under different reading purposes: an eye-tracking, keystroke-logging, and stimulated recall study

Abstract This study explored second language (L2) reading and recall processes under different reading purposes, as reflected in their eye-movements during reading, keystrokes produced from summary writing, and stimulated recall comments. Seventy-two Korean undergraduate students read an English essay for different purposes, i.e., reading to extract the gist quickly (i.e., reading-to-skim) versus reading to prepare for a presentation (i.e., reading-to-learn), and wrote an unannounced summary of the essay. A subgroup of participants further produced stimulated recalls prompted by their own eye-movements and keystrokes. The results revealed that reading-to-skim led participants to engage in uninterrupted global text processing as manifested in significantly longer forward saccades and regressions. Those under the reading-to-learn condition, in contrast, showed significantly shorter eye-movements accompanied by constant pauses for local processing, while staying substantially longer on the essay. Reading-to-learn further resulted in more frequent pauses and revisions in the summary writing process, recalling a greater number of idea units from the essay. The findings of this study indicate that L2 learners prioritize distinct aspects of text processing depending on the reading purpose, which affects both reading and recall processes.
An insight to motorized two and three wheel crashes in developing countries: A case study in Sri Lanka

ABSTRACT Road traffic injury is a leading cause of mortality and morbidity in Sri Lanka. In 2014, 35,967 crashes were reported of which 6% were fatal, causing 2,440 deaths. Motorcycles account for more than 50% of the vehicles registered in the country and have been involved in over 50% of the total fatalities in 2014. Three-wheelers, being the second highest registered vehicle category in the country, have been involved in 16% of the fatalities in the same year. An analysis of motorcycle and three-wheeler crashes was done using the Sri Lanka Police Accident Database, vehicle registration details, and population data. On average, four people died per day from motorcycle and three-wheeler crashes in 2013. Not having a valid driving license upon a crash, rear-end crashes, age group 21 to 25 years, and single-vehicle crashes were some of the significant risk factors associated with motorcycle crashes. Aggressive or negligent driving, crash being a rolled over crash, driver age group 26 to 30 years were some of the significant factors associated with three-wheeler crashes. Promotion of public transport, strict law enforcement on helmet usage, design change of three-wheelers to restrict narrow turns. and more road safety education are suggested to mitigate this issue.
Improving collaborative learning in online software engineering education

ABSTRACT Team projects are commonplace in software engineering education. They address a key educational objective, provide students critical experience relevant to their future careers, allow instructors to set problems of greater scale and complexity than could be tackled individually, and are a vehicle for socially constructed learning. While all student teams experience challenges, those in fully online programmes must also deal with remote working, asynchronous coordination, and computer-mediated communications all of which contribute to greater social distance between team members. We have developed a facilitation framework to aid team collaboration and have demonstrated its efficacy, in prior research, with respect to team performance and outcomes. Those studies indicated, however, that despite experiencing improved project outcomes, students working in effective software engineering teams did not experience significantly improved individual achievement. To address this deficiency we implemented theoretically grounded refinements to the collaboration model based upon peer-tutoring research. Our results indicate a modest, but statistically significant (p = .08), improvement in individual achievement using this refined model.
Dislocation Generation in Experimentally Shocked Olivine Crystals

During shock metamorphism, crystals in planetary bodies are exposed to extreme conditions of stress, pressure, and temperature, resulting in the development of a range of shock‐induced defects, including dislocations. To investigate the shock‐induced development of dislocations in olivine, one of the most common minerals found in meteorites and other planetary samples, a series of shock experiments were carried out on olivine single crystals. Olivine crystals were shocked to peak reverberation pressures ranging from 21.3 to 58.7 GPa in a flat‐plate accelerator. The crystals were characterized using electron backscatter diffraction (EBSD), Raman spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy, and electron microprobe. EBSD analyses reveal that geometrically necessary dislocations form on all common slip systems. Raman spectroscopy reveals that the full width at half height of characteristic peaks increases linearly as a function of shock pressure. Dislocation loops with the Burgers vector b = [001] have higher densities near fractures as revealed by TEM analyses, whereas dislocations away from fractures are more dependent on the crystal orientation relative to impact direction. The type and density of dislocations that form during shock are largely independent of the starting hydrogen content of crystals. Calculations that incorporate post‐shock cooling rates of meteorites ejected from planetary surfaces, dislocation annihilation rates in olivine, and dislocation densities measured in shocked olivine suggest that shock‐induced dislocations are preserved in olivine in meteorites ejected from planetary bodies and therefore give insight into the conditions of ancient impact events in the solar system.
Patterns of injury mechanism at a tertiary trauma center in Mumbai, India: Opportunities for injury prevention

ABSTRACT This study aims to describe patterns of injury mechanism among patients treated at a tertiary trauma center in Mumbai to identify opportunities for targeted injury prevention strategies. Data were collected from an institutional trauma registry, and all patients presenting with life- or limb-threatening injuries over a 16- month period were included. Univariate and bivariate analyses were performed for demographic characteristics, injury mechanisms, and clinical outcomes. A total of 1,115 patients were treated during the study period, and the in-hospital mortality rate was 32% in this severely injured cohort. More than one half of patients were suffered transportation injuries (58%). Of victims of transportation injuries, 45% were victims of railway injuries and 28% were pedestrians struck by motor vehicles. Mortality was highest among victims of railway injuries (42%) and pedestrians struck by automobiles (38%). Although injury prevention is a major public health concern worldwide, it is important to understand local patterns of injury to guide targeted prevention strategies. This study highlights the utility of trauma registries in collecting crucial injury surveillance data. In this context, a focus on pedestrian safety and railway injury prevention is warranted.
In memory of Bruno Peter: fresh insights on the Swiss sawfly fauna (Hymenoptera, Symphyta)

Bruno Peter-Sager (1943–2018) was a Swiss entomologist who collected and studied sawflies, and published on these under the name Bruno Peter. His large collection is deposited in the Senckenberg Deutsches Entomologisches Institut, Müncheberg, Germany. Following a short biography, we present commentaries on noteworthy specimens from Switzerland and some general and specific characteristics of the Swiss sawfly fauna, based on his collection and database. Twenty sawfly species are recorded for the first time in Switzerland: Aprosthema bifurca, Arge fuscipennis, Cladardis hartigi, Dolerus altivolus, D. brevicornis, D. zhelochovtsevi, Empria fletcheri, Euura amentorum, E. cyrnea, E. longiserra, E. scotonota, Nescianeura noblecourti, Pristiphora depressa, P. luteipes, P. nigricans, Rhogogaster polaris, Taxonus alboscutellatus, Tenthredo semicolon, Tenthredopsis tischbeinii and Calameuta idolon. Three species are removed from the national list: Cladardis bordonii, Taxonus sticticus and Tomostethus melanopygius. Records from Switzerland of seven little-known or rarely recorded species are also discussed. Data for most specimens collected by B. Peter include altitude, enabling presentation of results of some analyses of species richness related to altitude, as well as examples of patterns of altitudinal abundance for selected species.
The Multifaceted Role of Social Capital for Achieving Organizational Ambidexterity and Supply Chain Resilience

With the increasing frequency and impact of disruptions (i.e., in the wake of COVID 19, Suez Canal blockage), researchers and practitioners are faced with an ongoing challenge to enable supply chain resilience. Drawing on the theory of paradox and ambidexterity, this study highlights paradoxes in enabling supply chain resilience and proposes that firms manage such paradoxes by developing an ambidexterity capability. We build a research model hypothesizing the role of social capital that enables organizational ambidexterity to realize supply chain resilience. The model is tested using structural equation modeling comprising survey data of 204 Pakistani manufacturing firms. Based on the results of this article, our overall model finds support with the exception that cognitive capital is not related to ambidexterity. This research contributes to the further conceptualization of paradoxes in supply chain resilience and advances the theory for a more comprehensive understanding of the impact of organizational social capital on ambidexterity.
Broad pattern and reason of sheep rearing: A study on sheep farming in Kashmir

The study was undertaken in the Ganderbal district of the Jammu and Kashmir. Ganderbal district is rich in the mountainous alpine pastures and sheep rearing is the core activity of people living in the high altitudes. There are three Zones based on the altitude and from each Zone, 120 sheep farmers were chosen making a total of 360 for this study. The sheep rearing in the district was divided into two main phases i.e., Migratory and Non-Migratory. Migratory phase is spent on the high alpine pastures of the district and non-migratory phase mild grazing and stall feeding is done. The main reason for the farmers choosing sheep farming as an occupation was the proliferation of the sheep followed by adaptability of the sheep to Kashmir and family business of the farmers. The least preferred reason for farmers to rear sheep include least expensive to start and easier to manage. Infact, there is need for the conservation of the high land pastures scientifically because they form the backbone of sheep rearing in Kashmir.
