Magnetic Levitation With Cylindrical Magnets for Density-Based Measurement

Magnetic levitation (MagLev) based on the magneto-Archimedes effect is an emerging technology for density measurement and analysis. However, the most commonly used standard MagLev faces the problem of cumbersome and time-consuming calculation procedures when analyzing the levitation behavior of samples in the whole working region. This work explores a new MagLev configuration using two cylindrical permanent magnets called “cylindrical MagLev” to solve the above issue. A theoretical model is developed to rapidly determine the relationship between the density of samples and their levitation height when they are stably levitated along the centerline of the MagLev system. Meanwhile, numerical simulations with a simple two-dimensional (2-D) symmetrical model are performed to reveal the levitation characteristics of samples in the whole working region with regard to measurement linearity, sensitivity, and magnetic force distribution, which are well-verified by experiments. On this basis, the performance of the developed cylindrical MagLev for density measurement is investigated using both linear and nonlinear measurement regions, and measurement uncertainties are evaluated. The proposed cylindrical MagLev exhibits similar performance to the standard MagLev, but its system design and performance analysis become much simpler and more convenient. Therefore, it is expected to replace the latter as a general MagLev configuration in practical applications such as density-based measurement, separation, and detection.
Tendencies of Telecommunication Companies Development in the Conditions of Ukrainian Society Digitalization

The article elaborates theoretical and methodological provisions and practical recommendations for development of telecommunication companies in conditions of Ukrainian society digitization. It is established that the development of Ukrainian telecommunications companies is cyclical and depends on indus- trial ambitions of global technology corporations, on investments in research and development, consumer requirements and needs for communication. A pilot study was conducted and a method- ology for determining the level of consumer satisfaction with tel- ecommunication services was developed, based on the synthesis of individual assessments according to certain characteristics of services with criteria of importance of this or that characteristic for consumers. The tendency of dependence of demand for telecommunication devices and services on cumulative marketing pressure of technological and telecommunication companies in the conditions of digitalization of Ukrainian society was revealed. Consumers of innovative models of telecommunications devices are putting pressure on operators and providers and demanding the functionality of equipment, density and technological ex- cel-lence of telecommunications networks. These criteria become crucial when Ukrainian households choose certain companies to receive telecommunications services. The scientific novelty of the obtained results is to develop a method for determining the level of consumer satisfaction with telecommunication services based on the synthesis of individual assessments of certain characteristics of services with importance criteria of a particular characteristic for consumers.
Needle Shape Sensing With Fabry-Perot Interferometers

A novel approach for fiber optics shape sensing, applicable to mini-invasive bio-medical devices, is presented. A kinematic model based on rotation vector is established and used to predict the trajectory. The movement of the flexible needle caused by two control inputs (the straight forward and the bevel orientation velocity) is described as the circular motion around the equivalent axis and the rotation of the needle axis. The model is simple, precise and efficient, and has an acceptable reconstruction effect on complex spatial curves. With the characteristics of compact structure (less than $100~ \mu \text{m}$ ), high strain sensitivity, low temperature sensitivity and ultra-low cost, Fabry-Perot interferometer (FPI) is used for curvature sensing. Calibration experiments show that FPI has higher (more than three times) curvature sensitivity and lower curvature-temperature cross sensitivity than fiber Bragg grating. The three dimensional shape sensing is obtained by converting the measured bending curvature and shape deformation using the proposed kinematic model.

SYNTHESIS, CHARACTERIZATION, ANTIFUNGAL ACTIVITY AND STRUCTURE– ACTIVITY RELATIONSHIPS: STUDY OF SOME MONO- AND DI-SCHIFF BASES

Schiff bases (SB) are an important type of organic compounds and have a wide range of biological activities due to commercial and pharmaceutical trading uses. The different activities of these compounds induced the researchers to synthesized and studied new types of these compounds. Two series of Schiff base derivatives were synthesized by the condensation reactions of substituted aldehydes salicylaldehyde, 4-(N,Ndimethylamino) benzaldehyde or 2,4-dimethoxybenzaldehyde with 2-amino-5-iodobenzoic acid (1:1) or with 3,5- diamenobenzoic acid (1:2) in ethanol absolute as a solvent. Different analytical techniques characterized the structure of the synthesized Schiff bases; for instance, Fourier transform infrared FT-IR and proton nuclear magnetic resonance 1H-NMR. The purity of the synthesized compounds was tested by elemental microanalysis CHN and thin layer chromatography TLC. The structural properties of the studied molecules were investigated theoretically by performing density functional theory (DFT) using the HyperChem software. The lipophilicity of the tested compounds showed that the compounds 2c, 2b, 2a, and 1c have logP values less than (5), 2.90, 3.78, 3.82 and 4.57, respectively, whereas, 1b and 1a have logP values higher than (5), 5.01 and 5.03, respectively. The Mulliken charge distribution showed that the carbonyl oxygen atom of the carboxylic group is more negative (~ - 0.4) as compared to other oxygen atoms (~ -0.3) in all selected compounds. Frontier molecular orbitals energy diagram and their bandgap provided indications about chemical reactivity and kinetic stability of the molecules. The synthesized compounds were tested for antifungal effects against Aspergillus niger and Candida albicans, which indicated that the compounds had good antifungal activity.
Communicating Values to Cultivate Sustainable Occupational Identity: How Restaurant Workers Resist Service Work Stigma

Pre-COVID-19 pandemic, restaurant workers comprised one of the largest workforces in the United States, contributing hundreds of billions of dollars to the national economy. Yet, restaurant workers routinely face customer abuse, meager wages, lack of benefits, sexual harassment, and one of the highest rates of turnover across industries. Given these conditions, this qualitative study investigates how restaurant workers make sense of a contested occupation and manage the stigma associated with their occupation. Specifically, this study examines how food and beverage service workers identify with and navigate a demanding industry while managing the sociocultural assumptions of service work. Using a multi-level discourse analytic framework, we analyze how service workers craft and enact occupational identities. Through an analysis of in-depth interviews with 19 restaurant employees, we demonstrate how people foreground the positive attributes of restaurant work while resisting social Discourses that position the work as dirty, demeaning, emotional, and meaningless. We analyze how workers frame the values of working in restaurants and the communicative strategies they use to navigate stigmatized social interactions, including emphasizing flexibility, empathy, emotion management, and teamwork. Theoretical and practical implications offer suggestions to improve workforce sustainability and working conditions for employees.
On the Estimation of a Convex Set From Noisy Data on Its Support Function

In problems of medical imaging and robotic vision, measurements of a convex set are sometimes obtained via the set's support function. The standard way in which the convex set is recovered from such data is to suppose that it is polygonal, model the errors as Normal random variables, and apply constrained maximum likelihood methods. Typically, the number of sides assumed of the polygon is equal to or a little less than the number of data points. However, from a statistical viewpoint, the number of sides should really be interpreted as a smoothing parameter and chosen to optimize some measure of performance. Additionally, if the true set is not a polygon, then a polygonal estimate can be aesthetically unsatisfactory. In this article we suggest periodic smoothing methods for estimating the convex set.
The effect of Sr and Mg substitutions on the mechanical properties and solubility of the fluorapatite ceramics for biomedical applications

The ionic substitutions play important role in the modifications of the biological apatites. Recently, the attention has been focused on the co-doping effects of additives on the functional properties of apatite based biomaterials. Under a research work for which the results are presented here, the dense samples of fluorapatites: Ca 10 (PO 4 ) 6 F 2 and Ca 8 MgSr(PO 4 ) 6 F 2 were produced after sintering at a temperature of 1250 °C for 6 hours in air. The XRD, IR and Raman spectrometry results show a high crystallinity of the fluorapatite and strontium-magnesium-doped fluorapatites. The results demonstrate the stability of structural and mechanical properties of fluorapatites after immersion tests in saline and buffer solutions. The durability of mechanical properties and biocompatibility of Ca 10 (PO 4 ) 6 F 2 and Ca 8 MgSr(PO 4 ) 6 F 2 fluorapatites make these materials highly attractive for biomedical application.
Bibliometric analysis of productivity and keyword trends of articles on physical therapy and aging (1990-2014)

Introduction. The increase in population longevity has led the subject of ageing to take an important role in research and innova-tion policies. Considerable efforts have been made worldwide to promote research on physiotherapy and ageing. Therefore, applying bibliometric measures can be useful to identify emerging and innovative scientific indicators. This study identifies productivity and topic trends in physiotherapy in ageing and the main publishing authors, institutions, and countries. Methods. A bibliometric analysis was applied in original articles published on the Science Citation index Expanded of Web of Science Core Collection (1990–2014). Bibliometric indicators were obtained by using specific bibliometric software. Pearsons’ correlation coefficient (r) was applied for correlations; statistical significance was considered for p < 0.01. Results. overall, 2237 original articles were included. Topic trends show an initial focus on illness and evolve towards the study of prevention. Authors and institutions increased productivity and citation. The most productive country was the United States, and there was a significant correlation between productivity and gross domestic product ( p < 0.01). No statistically significant relationship was observed between productivity and the countries’ aged population. Conclusions. Productivity increased, with a greater scientific interest in prevention. The published research was mainly re- lated to wealthy and developed countries.
Torque Ripple and Radial Force Minimization of Fractional-Slot Permanent Magnet Machines Through Stator Harmonic Elimination

This article proposes a torque ripple minimization strategy based on minimizing interactive space harmonics of fractional-slot permanent magnet (PM) machines using a space-shifted wye–delta stator winding. A radial force analysis has also been carried out, which showed a substantial reduction in the second-order mode for these space-shifted wye–delta wound machines; this will improve the noise and vibration performance. The effectiveness of the proposed method is shown by analyzing the performances of a low-power surface-mounted permanent magnet (SPM) machine for the electric power steering (EPS) applications and a high-power interior permanent magnet (IPM) machines for the hybrid electric vehicle (HEV) applications on the 12-slot/10-pole (12 S/10 P) configuration. The proposed winding doubles the stator slot number of the base model, and as a result, the base 12 S/10 P configuration becomes 24-slot/10-pole (24 S/10 P) combination. Compared with the existing ripple minimization techniques of magnet shaping or rotor skewing, the proposed stator winding-based strategy achieves better torque ripple performance and magnet utilization leading to an improvement in average torque while reducing the amplitude of the low-order radial force. A 10-pole SPM machine has been built and tested for experimental validation of both the concept and the finite element analysis (FEA) simulation results.
An Integrated System for initial Prediction for Autism Spectrum Disorders

Autism Spectrum Disorder ASD specifies where lots of behavioral disabilities, such as social connections and lack of commutating, repetitions of same works, and only single areas are focused. While ASD is noticed in initial stage, some deficiencies and behavioral patterns may not be found as the indication unless they affect a person’s life in a particular way. An infrastructure to record, detect and label the behavioural patterns of children with Autism Spectrum Disorder (ASD) has been developed. Autism Spectrum Disorder (ASD) effects the entire life of a person. The major symptoms of ASD are noticed as lack of social contact and communication, same pattern recurrence, predetermined interests and works. The critical issues is ASD identified at initial stage and age. This study, the grouping technique for ASD diagnosis was utilized in children aged 4-11 years. The Linear Discriminant Analysis (LDA) and KNN algorithms are used for categorizing.
Distribution and Dispersion of Heavy Metals in the Rock–soil–moss System in Areas Covered by Black Shale in the Southeast of Guizhou Province, China

Black shales are easily exposed duo to human activities such as mining, road construction, and shale gas development, which results in several environmental issues including heavy metals (HMs) pollution, soil erosion and the destruction of vegetation. Moss are widely used to monitor metal pollution in the atmosphere, but few studies on the distribution and dispersion of HMs in the rock – soil – moss system are available. Here, mosses (P. flexuosa Harv), growing soils, and corresponding parent rocks were collected from black shale areas. After appropriate pretreatment, samples were analyzed for multiple elements concentration by ICP-AES and ICP-MS. The results show that black shales parent rocks have elevated HMs concentration, and act as a source of multiple metals. Soil significantly inherit and accumulate heavy metals released from black shale. Significant positive correlations between HMs in P. flexuosa Harv and the growing soils indicate that HMs are mainly originating from geological source rather than atmospheric deposition. Compared with other elements, only the transfer factor (TF) of Cd is greater than 1, the normal functioning of mineral elements (K and Zn) absorption and transportation may contribute to its high tolerance to Cd. Finally, both the BCF and TF for most HMs in P. flexuosa Harv are less than 1, indicated that it has a tolerance and exclusion mechanism for these metals. Therefore, the luxuriant and spontaneous growth of P. flexuosa Harv could be used as a phytostabilization pioneer plant in the black shale outcrop where vascular plants are rare.
MiR-3146 Induces Neutrophil Extracellular Traps to Aggravate Acute Gouty Arthritis

MiR-3146 plays an important role in the formation of neutrophil extracellular traps (NETs) during the pathogenesis of acute gouty arthritis (AGA). The aim of our study was to explore the underlying role and molecular mechanism of miR-3146 in the formation of neutrophil extracellular traps (NETs) during the pathogenesis of acute gouty arthritis (AGA). The expression of miR-3146 and sirtuin 1 (SIRT1) was determined by real-time PCR and western blot. The luciferase reporter assay was performed to identify the targeting relationship between miR-3146 and SIRT1. Reactive oxygen species (ROS) production was detected by fluorescent staining. NETs formation was demonstrated via immunofluorescence staining and ELISA method. AGA model was induced in rats to verify the effects of miR-3146 inhibition on histopathological changes and NETs. Here, we found miR-3146 expression was dramatically increased in neutrophils of patients with AGA, presenting higher levels of NETs. Monosodium urate (MSU) crystals significantly increased miR-3146 expression and ROS production in neutrophils. The NETs process was also triggered by MSU crystals. Furthermore, we verified the interaction between miR-3146 and SIRT1. Additionally, antagomir-3146-based therapy effectively inhibited the formation of NETs in rats with AGA. MiR-3146-mediated NETs formation may play a potential role in the pathogenesis of AGA.

Modelling Satisfaction and Behavioural Intention of Malaysian Fine Dining Restaurants

Consumer satisfaction was long recognized by scholars and practitioners as one major ingredient for business survival and prosperity. Hence, the main purpose of this study was to offer an integrated approach to understanding consumer satisfaction and post-dining behavioural intentions by examining the causal relationship among five constructs of fine dining restaurant with satisfaction and behavioural intentions. The Likert scale survey instrument was used to collect data via the ‘drop-off and collect’ survey technique. The sample was drawn from participating restaurants in the Malaysia International Gastronomy Festival 2017.Four hundred and nineteen useable questionnaires were garnered from eight fine dining restaurants that agreed to participate in the study. A research model based on the expectancy-disconfirmation paradigm investigating the relevant relationships among the constructs by using a structural equation modelling (SEM) approach was proposed and tested. This study examined a mediating model of the relationship between the restaurant service/product dimensions, marketing dimension centred on customer-based brand equity constructs, satisfaction and revisit intention. A parsimonious model of restaurant satisfaction and behavioural (revisit) intention was successfully developed and the proposed framework was substantially validated with four hypotheses supported and seven not. Theoretical and practical implications with relevant and importance to academicians and practitioners were offered.
Nutrient and stress tolerance traits linked to fungal responses to global change

In this case study analysis, we identified fungal traits that were associated with the responses of taxa to 4 global change factors: elevated CO2, warming and drying, increased precipitation, and nitrogen (N) enrichment. We developed a trait-based framework predicting that as global change increases limitation of a given nutrient, fungal taxa with traits that target that nutrient will represent a larger proportion of the community (and vice versa). In addition, we expected that warming and drying and N enrichment would generate environmental stress for fungi and may select for stress tolerance traits. We tested the framework by analyzing fungal community data from previously published field manipulations and linking taxa to functional gene traits from the MycoCosm Fungal Portal. Altogether, fungal genera tended to respond similarly to 3 elements of global change: increased precipitation, N enrichment, and warming and drying. The genera that proliferated under these changes also tended to possess functional genes for stress tolerance, which suggests that these global changes—even increases in precipitation—could have caused environmental stress that selected for certain taxa. In addition, these genera did not exhibit a strong capacity for C breakdown or P acquisition, so soil C turnover may slow down or remain unchanged following shifts in fungal community composition under global change. Since we did not find strong evidence that changes in nutrient limitation select for taxa with traits that target the more limiting nutrient, we revised our trait-based framework. The new framework sorts fungal taxa into Stress Tolerating versus C and P Targeting groups, with the global change elements of increased precipitation, warming and drying, and N enrichment selecting for the stress tolerators.
