Properties of Basalt Fiber Core Rods and Their Application in Composite Cross Arms of a Power Distribution Network

As basalt fiber has better mechanical properties and stability than glass fiber, cross arms made of continuous basalt-fiber-reinforced epoxy matrix composites are capable of meeting the mechanical requirements in the event of typhoons and broken lines in coastal areas, mountainous areas and other special areas. In this paper, continuous basalt-fiber-reinforced epoxy matrix composites were used to fabricate the core rods and composite cross arms. The results verified that basalt fiber composite cross arms can meet the strict requirements of transmission lines in terms of quality and reliability. In addition to high electrical insulation performance, the flexural modulus and the flexural strength of basalt fiber core rods are 1.8 and 1.06 times those of glass fiber core rods, respectively. Basalt fiber core rods were found to be much better load-bearing components compared to glass fiber core rods. However, the leakage current and the result of scanning electron microscopy (SEM) analysis reveal that the interface bonding strength between basalt fibers and the matrix resin is weak. A 3D reconstruction of micro-CT indicates that the volume of pores inside basalt fiber core rods accounts for 0.0048% of the total volume, which is greater than the 0.0042% of glass fiber rods. Therefore, improving the interface bond between basalt fibers and the resin can further improve the properties of basalt fiber core rods.
Nanostructured Superhydrophobic Titanium-Based Materials: A Novel Preparation Pathway to Attain Superhydrophobicity on TC4 Alloy

This study develops the nanostructured superhydrophobic titanium-based materials using a combined preparation method of laser marking step and the subsequent anodizing step. The structural properties were determined using an X-ray diffractometer (XRD) and scanning electron microscope (SEM), while the performance was explored by wear and corrosion tests. The laser marking caused a rough surface with paralleled grooves and protrusions, revealing surface superhydrophobicity after organic modification. The anodizing process further created a titanium oxide (TiO2) nanotube film. Both phase constituent characterization and surface elemental analysis prove the uniform nanofilm. The inert nanosized oxide film offers improved stability and superhydrophobicity. Compared to those samples only with the laser marking process, the TiO2 nanotube film enhances the corrosion resistance and mechanical stability of surface superhydrophobicity. The proposed preparation pathway serves as a novel surface engineering technique to attain a nanostructured superhydrophobic surface with other desirable performance on titanium alloys, contributing to their scale-up applications in diverse fields.
Ditching the Driving: A Cross-Sectional Study on the Determinants of Remote Work From Home for Sign Language Interpreters

Background The coronavirus disease 2019 (COVID-19) pandemic dramatically impacted the working conditions for sign language interpreters, shifting the provision of interpreting services from onsite to remote. The goal of this cross-sectional study was to examine the perceptions of determinants of remote interpreting implementation from home by sign language interpreters during the pandemic. We hypothesized that interpreters working across the primary settings of staff (agency, government, business, or hospital employees), educational (K-12 or postsecondary), community/freelance (independent contractor), video remote (the two-way connection between onsite participants and remote interpreter), and video relay (three-way telecommunication) would present with differing experiences of the implementation process. Methods The Determinants of Implementation Behavior Questionnaire was adapted for sign language interpreters (DIBQ-SLI) and administered to certified interpreters working remotely at least 10 h per week. The DIBQ-SLI included eight constructs (knowledge, skills, self-efficacy, perceived behavioral control, innovation characteristics, organizational resources and support, innovation strategies, and social support) and 30 items. Parametric statistics assessed differences in interpreters' perceptions across settings. Principal component analysis was conducted for data reduction and affirmation of the most critical constructs and items. Results One hundred and six interpreters (37 video relay, 27 video remote, 18 educational, 11 community/freelance, 11 staff interpreters, and two from “other” settings) completed the DIBQ-SLI. The video relay and staff interpreters consistently demonstrated the most favorable and the educational interpreters demonstrated the least favorable perceptions. Of the total variance, 58.8% of interpreters' perceptions was explained by organizational (41%), individual (10.7%), and social (7.1%) dimensions. There were significant differences across settings for the organizational and individual principal components; however, no differences were detected for the social principal component. Conclusions An administrative infrastructure devoted to ensuring that interpreters receive sufficient managerial support, training, materials and resources, experience with remote interpreting before having to commit, and insights based on the results of their remote work (organizational principal component) may be necessary for improving perceptions. Remote interpreting is expected to continue after the pandemic ends; thus, settings with the least favorable ratings across behavior constructs may borrow strategies from settings with the most favorable ratings to help promote perceptions of the contextual determinants of future remote interpreting implementation.
Fitting Multidimensional IRT Models with R

Item response theory (IRT) is widely used in assessment and evaluation research to explain how participants respond to questions. IRT assumes that people respond to a test item according to their ability and the difficulty of the item. From the statistical point of view, IRT models are mixed-effects models because the difficulty of the items is a fixed effect, whereas the person ability is considered as a random effect. Currently, several R packages can be used to fit various IRT models. For example, the ltm package (Rizopoulos, 2006) can handle the Rasch model, the latent trait model, the three-parameter model, and the graded response model; and the eRm package (Mair & Hatzinger, 2007) can fit the rating scale model and the partial credit model. These packages, however, can only analyze unidimensional IRT models. Multidimensional IRT models have been proposed to account for multilevel or hierarchical data, in which subjects may be grouped into clusters and items may be nested within different dimensions. The lme4 package can be used to analyze multidimensional Rasch models for dichotomous outcomes (Doran, Bates, Bliese, & Dowling, 2007). For categorical responses, fitting multidimensional IRT models requires using commercial software such as SAS or Conquest. The paper presents an implementation of multidimensional IRT models for categorical outcomes in R and demonstrates its use with an illustrative example.
Effect of JPMR on State-Trait Anxiety among young female adult during COVID-19 pandemic lockdown

The worldwide pandemic situation that is caused by coronavirus disease 2019 (COVID-19) has led the population to a state of confinement, which has created a rise in state trait anxiety among people around us. COVID-19 affected our psychological state similarly as our physical health. The research design used in this study is quasi experimental research design and the questionnaire used was State Trait Anxiety Inventory (STAI Form Y-1 & Y-2 Charles D. Spielberger, 1983). Study includes 30 young female adult and out of that 15 subjects were taken into account as experimental group and were given the JPMR as the intervention plan for one month. The objective of our study is to find the effectiveness of JPMR on state trait anxiety. After the intervention data was analysed using paired t-test and correlation. Although result proved that for state anxiety obtained P value is 0.000 which is significant at 0.01 level (t =7.08, p=0.000) indicating that JPMR therapy was effective in reducing the state anxiety for the experimental group. No significant difference found in trait anxiety in both experimental and control group.
Comparison of the Oral Microbiota Structure among People from the Same Ethnic Group Living in Different Environments

The characteristics of the oral microbiota may depend on oral health, age, diet, and geography, but the influence of the geographic setting on the oral microbiota has received limited attention. The characteristics of oral microbiota have been reported to differ between urban and rural environments. In order to minimize the influence of genetic background, we recruited 54 volunteers from the same ethnic group, living in urban and rural areas of Gansu Province, China. We collected dental plaque samples and divided them into four groups according to the participant's area of residence and dental caries status. We sequenced the 16S rRNA of these samples using the Pacific Biosciences sequencing platform and analyzed the correlation between the geographic area and the characteristics of the oral microbiota. Analysis of the alpha and beta diversity revealed that there were significant differences in diversity and composition of dental plaque microflora among the four groups. Cluster analysis revealed that geographic area played an important role in determining the oral microbiota. Network analysis of oral microorganisms showed that geographic differences had major influence on the composition characteristics and internal structure of oral microorganisms. We found that some dominant strains which may play a key role in maintaining oral health, such as Streptococcus oralis, Capnocytophaga sputigena, Porphyromonas catoniae, Corynebacterium matruchotii, Haemophilus parainfluenzae, and Prevotella loescheii, were less affected by the geographic setting. These results provide a deeper understanding of factors influencing the composition of the oral microbiota and could contribute to early diagnosis and effective prevention of dental caries in different settings.
Stereomicroscope with Imaging Analysis: A Versatile Tool for Wetting, Gel Formation and Erosion Rate Determinations of Eutectic Effervescent Tablet

Wettability, gel formation and erosion behaviors could influence the drug release pattern of solid dosage forms. Typically, these parameters are evaluated using a variety of techniques. Nonetheless, there has been no previous research on versatile tool development for evaluating several tablet characteristics with a single tool. The aim of this study was to develop the versatile tool for measuring various physical properties of eutectic effervescent tablets and also investigate the relationship between these parameters with parameters from drug dissolution. Ibuprofen (IBU)-poloxamer 407 (P407) eutectic effervescent tablets were fabricated with a direct compression method. Their wetting properties, gel formation and erosion behaviors were investigated using a stereomicroscope with imaging analysis in terms of the liquid penetration distance, gel thickness and erosion boundary diameter, respectively. In addition, the dissolution rate (k) and disintegration time of eutectic effervescent tablets in 0.1 N HCl buffer pH 1.2 were also determined. Incorporation of P407 into the IBU tablet improved the tablet wetting properties with increasing liquid penetration distance under stereoscope. CO2 liberation from effervescent agents promoted tablet surface roughness from matrix erosion. The relationship between observed physical properties and disintegration and dissolution parameters suggested that the combination of erosion by effervescent agents and gel formation by P407 had a potential influence on dissolution enhancement of the formulation. Therefore, a developed stereomicroscope with an imaging analysis technique was exhibited as an alternative versatile tool for determining the wetting properties, gel formation and erosion behaviors of pharmaceutical solid dosage forms.
Water-soluble fullerene derivatives have shown promise as drug carriers to bypass the brain and ocular barriers

The water-soluble, hydroxylated fullerene [fullerol, nano-C60(OH)22–26] has several clinical applications including use as a drug carrier to bypass the blood ocular barriers. We have assessed fullerol's potential ocular toxicity by measuring its cytotoxicity and phototoxicity induced by UVA and visible light in vitro with human lens epithelial cells (HLE B-3). Accumulation of nano-C60(OH)22–26 in the cells was confirmed spectrophotometrically at 405 nm and cell viability estimated usingMTS and LDH assays. Fullerol was cytotoxic to HLE B-3 cells maintained in the dark at concentrations higher than 20 μM. Exposure to either UVA or visible light in the presence of N5 μM fullerol-induced phototoxic damage.When cells were pretreated with non-toxic antioxidants: 20 μM lutein, 1 mM N-acetyl cysteine, or 1 mM L-ascorbic acid prior to irradiation, only the singlet oxygen quencher-lutein significantly protected against fullerol photodamage. Apoptosis was observed in lens cells treated with fullerol whether or not the cells were irradiated, in the order UVANvisible lightNdark. Dynamic light scattering (DLS) showed that in the presence of the endogenous lens protein α-crystallin, large aggregates of fullerol were reduced. In conclusion, fullerol is both cytotoxic and phototoxic to human lens epithelial cells. Although the acute toxicity of water-soluble nano-C60(OH)22–26 is low, these compounds are retained in the body for long periods, raising concern for their chronic toxic effect. Before fullerols are used to deliver drugs to the eye, they should be tested for photoand cytotoxicity in vivo. Published by Elsevier Inc.
Highly Compact GCPW-Fed Multi-Branch Structure Multi-Band Antenna for Wireless Applications

In this work, we present a highly compact multi-branch structure multi-band antenna with a grounded coplanar waveguide (GCPW)-fed structure printed on 26 × 13 × 1.6 mm 3 sized FR-4 substrate having dielectric constant ε r of 4.3 and loss tangent δ of 0.02. In the proposed antenna, five branches are extended from the main radiator to provide multi-band behavior. Two branches are introduced at the upper end of the main radiator, effectively covering the lower bands, while the other three branches are introduced near the center of the main radiator to extend operation to higher bands. The designed antenna covers five different bands: 2.4 GHz, 4.5 GHz, 5.5 GHz, 6.5 GHz, and 7.8 GHz, with respective gain values of 1.34, 1.60, 1.83, 1.80, and 3.50 dBi and respective radiation efficiency values of 90, 88, 84, 75, and 89%. The antenna shows a good impedance bandwidth, ranging from 170 MHz to 3070 MHz. The proposed antenna is simulated in CST Microwave Studio, while its performance is experimentally validated by the fabrication and testing process. The antenna has potential applications for IoT, sub-6 GHz 5G and WLAN (both enablers for IoT), C-band, and X-band services.
Display Method of the Sky Color Taking into Account Multiple Scattering

Research on the rendering of natural scenes, such as clouds, ocean waves, trees, terrain, grass, and re, has been growing very popular. This paper reports a shading model for sky color which is indispensable for natural scenes. In most cases, the sky color in outdoor scenes is blue in computer graphics for the sake of simplicity. However, the color of the sky is not simply blue. It changes according to viewing direction, the position of the sun, and conditions of the atmosphere. The sky plays an important role in architectural design and ight simulators. The color of the sky is determined by the scattering and absorption of air molecules, aerosols and other small particles in the atmosphere. In the previous method, only single scattering was taken into account for the sky color calculation. To display realistic images, multiple scattering can not be ignored. This paper proposes two methods: a fast method to calculate the spectral distribution of sky radiation for single scattering, and an efcient method to calculate the sky color taking into account multiple scattering.

Current damping in superconducting junctions with nonequilibrium electron distribution functions

The effect of the nonequilibrium electron distribution functions in the superconductors on the properties of a tunneling junction is investigated. The state of nonequilibrium gives rise to a sharp increase in the effective temperature of the junction and an increase in the decay probability for the metastable current state. When the state of nonequilibrium is at a level higher than the threshold level, the effective temperature is negative. In this case phase and voltage oscillations arise in the junction at a current value lower than the critical value.
ULF oscillations in the terrestrial magnetosphere

The terrestrial magnetosphere is pervaded by ULF oscillations of the space-plasma electric and magnetic fields. A ULF null direction-finding technique was devised for ground magnetometer data which showed an underlying high-latitude direction of arrival biased towards the morning sector. To understand this, the classical Helmholtz equation, which explains the propagation of electromagnetic and acoustic waves, was numerically solved for simulated plane-parallel ULF waves incident on MHD magnetospheric data. The resulting simulation shows waveguiding around the terrestrial Alfvén gradient through the region threaded by high-latitude magnetic field-lines, as well as the existence of ULF lobes in the magnetotail and diffraction of ULF waves in the tail plasma sheet. Polar satellite ULF data was classified into six magnetospheric groups during the Autumn seasons of 2002 and 2003 at times when the Polar satellite field line trace was between Finland and Greenland. Thirty-nine observations are presented where the magnetospheric signals coincided with a terrestrial event. Three of the magnetospheric groups are concerned with Poynting flux impulses [PFIs] and their detection in Polar satellite data was shown to be coincident with enhanced absorption in IRIS riometer data. These PFIs were shown to mark the time when the trajectories of charged particles are redirected towards the Earth. The intensity of these PFIs was shown to be sufficient to provide electrons with auroral energy. Multiple pulsed PFIs were also observed which could transfer substantial energy to trapped electrons, be related to oscillatory magnetic reconnection and explain auroral optical modulation. Observations were made of magnetospheric events related to the onset and expansion phase of substorms and of a related phenomena which had the useful property of temporal and spatial localisation that enabled it to be mapped and the sequence of ionospheric precipitation deduced. Eleven observations were also made of the electromagnetic quadrature signature of field line resonance.
