FEATURES OF THE LABOR MARKET IN THE FIELD OF PHYSICAL CULTURE AND SPORTS
Authors: Мурашева Мария Викторовна 
Published: August 2021

Основой организации труда физкультурных работников является его нормирование. С помощью нормирования определяются общая численность физкультурных работников, количественные соотношения между различными категориями работающих, реализуются возможности роста эффективности их труда. Нормы труда, устанавливаемые физкультурным работникам, зависят от особенностей их деятельности и методов измерения объёма выполняемых ими работ. Особенность нормирования труда ряда категорий физкультурных работников (например, тренеров, инструкторов, организаторов) состоит в том, что результаты труда работников не осуществляются в продукте, а выступают в форме нематериального блага.
The basis of the organization of the labor of physical education workers is its rationing. With the help of rationing, the total number of physical education workers is determined, quantitative relations between different categories of working, the possibilities of growth in the effectiveness of their labor are being implemented. Labor standards established by physical workers depend on the peculiarities of their activities and methods for measuring the volume of work performed by them. The peculiarity of the laboring of the labor of a number of categories of physical education workers (for example, coaches, instructors, organizers) is that the results of workers are not carried out in the product, but perform in the form of an intangible good.

Abstract
Stochastic field distortions caused by atmospheric turbulence are a fundamental limitation to the astrometric accuracy of ground-based imaging. This distortion field is measurable at the locations of stars with accurate positions provided by the Gaia DR2 catalog; we develop the use of Gaussian process regression (GPR) to interpolate the distortion field to arbitrary locations in each exposure. We introduce an extension to standard GPR techniques that exploits the knowledge that the 2D distortion field is curl-free. Applied to several hundred 90 s exposures from the Dark Energy Survey as a test bed, we find that the GPR correction reduces the variance of the turbulent astrometric distortions ≈12× , on average, with better performance in denser regions of the Gaia catalog. The rms per-coordinate distortion in the riz bands is typically ≈7 mas before any correction and ≈2 mas after application of the GPR model. The GPR astrometric corrections are validated by the observation that their use reduces, from 10 to 5 mas rms, the residuals to an orbit fit to riz-band observations over 5 yr of the r = 18.5 trans-Neptunian object Eris. We also propose a GPR method, not yet implemented, for simultaneously estimating the turbulence fields and the 5D stellar solutions in a stack of overlapping exposures, which should yield further turbulence reductions in future deep surveys.
Modeling the Variable Polarization of ϵ Aurigae In and Out of Eclipse
Authors: Ignace Richard , Henson Gary , Neilson Hilding , Asbury William 
Published: August 2021

Abstract
The eclipsing binary ϵ Aur is unique in being a very-long-period binary involving an evolved, variable F star and a suspected B main-sequence star enshrouded in an opaque circumstellar disk. The geometrical arrangement is that the disk is viewed almost perfectly edge on, with the alignment leading to a partial eclipse of the F star. Despite a global observing campaign for the 2009–11 eclipse, there remain outstanding questions about the nature of the binary, its components, the disk, and the evolutionary state of the system. We analyze optical-band polarimetry in conjunction with broadband color variations to interpret brightness variations across the surface of the F star. We model this both during and after the 1982–84 eclipse for which an extensive and dense data set exists. We develop a model in terms of surface temperature variations characterized by a small global variation overlaid with a temperature variation described with low-order spherical harmonics. While not providing a detailed fit to the data set, our modeling captures the overall characterization of the color and polarimetric variability. In particular, we are able to recover the gross behavior of the polarimetric excursion in the Q–U plane as observed during eclipse of the F star when compared to posteclipse behavior.
Meterwavelength Single-pulse Polarimetric Emission Survey. V. Flux Density, Component Spectral Variation, and Emission States
Authors: Basu Rahul , Mitra Dipanjan , Melikidze George I. 
Published: August 2021

Abstract
We present the flux density measurements of the pulsars observed in the Meterwavelength Single-pulse Polarimetric Emission Survey. The average flux densities were estimated in 113 pulsars at two frequencies of 325 and 610 MHz using interferometric imaging. The average profile and single-pulse emission in each pulsar were calibrated using the estimated flux density. We have used the flux-calibrated average profile to study the variation of the spectral index across the emission beam in 21 pulsars where the core, inner cone, and the outer conal components could be clearly identified. The central core component showed a steeper increase in emission at the lower frequency compared with conal emission, with an average difference in spectral index δα
core-cone ∼ −0.7 between the core and the conal components in this frequency range. In contrast, the inner conal components had positive difference in their spectral index compared to the outer cones with average difference δα
in-out ∼ +0.3. The variation in the spectral index across the pulse window should provide valuable inputs for constraining the radio emission processes. The single-pulse emission showed the presence of emission mode changing in 12 pulsars, with three cases where the phenomenon is being reported for the first time. In addition, we have also detected enhanced emission for short durations or flaring, in parts or across the entire emission window in 14 pulsars. The sudden changes in the emission during mode changing, as well as these bursting states, are unrelated to the emission mechanism and suggest the presence of rapid and repetitive changes during the plasma generation process.

Published: August 2021

Abstract
Objective: Migration is a problem affecting all family members, but particularly children. Child refugees are the highest risk group for the health systems of receiving countries. We investigated the health of 104 Syrian child refugees presenting to a tertiary hospital in Turkey. Settings and Design: A retrospective study was conducted in the pediatric clinic. Materials and Methods: The medical files of Syrian refugee children (0–18 years) presenting to Adiyaman University Hospital, Pediatric Clinic between 01 and 30 November 2015, were investigated. Demographic data, body measurements, and laboratory results obtained from patients' medical records were evaluated. Results: Mean age of patients was 53.5 ± 49.6 (2–198) months; 63 were male and 41 were female. Seventy-two patients (69.2%) were under 5 years of age. Weight in 20 patients (19.2%), height in 33 (31.7%), head circumference in 2 (1.9%), and body mass index in 7 (6.7%) were below the third percentile. All patients with body weight below the third percentile had chronic malnutrition. Anemia was present in 35 (50%) of the 70 patients for whom complete blood count data were available. Conclusion: Health workers involved with Syrian refugee children must consider the two preventable conditions; malnutrition and anemia.

ABSTRACT.
Rotavirus is responsible for 26% of diarrheal deaths in Latin America and the Caribbean. Haiti introduced the monovalent rotavirus vaccine in April 2014. The objective of this analysis is to describe the impact of the rotavirus vaccine on hospitalizations among Haitian children younger than 5 years old during the first 5 years after introduction. This analysis includes all children with diarrhea who were enrolled as part of a sentinel surveillance system at two hospitals from May 2013 to April 2019. We compare the proportion of rotavirus-positive specimens in each post-vaccine introduction year to the pre-vaccine period. To account for the potential dilution of the proportion of rotavirus-positive specimens from a waning cholera outbreak, we also analyzed annual trends in the absolute number of positive stools, fit a two-component finite-mixture model to the negative specimens, and fit a negative binomial time series model to the pre-vaccine rotavirus-positive specimens to predict the number of rotavirus diarrhea hospital admissions in the absence of rotavirus vaccination. The overall percentage of rotavirus-positive specimens declined by 22% the first year after introduction, increased by 17% the second year, and declined by 33% to 50% the subsequent 3 years. All sensitivity analyses confirmed an overall decline. We observed a clear annual rotavirus seasonality before and after vaccine introduction, with the greatest activity in December through April, and a biennial pattern, with high sharp peaks and flatter longer periods of increased rotavirus activity in alternating years, consistent with suboptimal vaccination coverage. Overall, our study shows evidence that the introduction of the rotavirus vaccine reduced the burden of severe rotavirus diarrhea.
Investigating the Effect of Gypsum Powder on Chemical Constituents of Soil and Selected Crops, Adigudem, Tigray, Ethiopia
Authors: Hailu Berhe , Estifanos Samuel 
Published: August 2021

This paper investigates the effects of gypsum powder from the gypsum plant in Adigudem on chemical properties of soil as well as the yield of two major crops, wheat (Triticum aestivum) and barley (Hordeum vulgare). Three mixes of 10kg of soil with 0%, 10%, 30%, and 50% proportion of gypsum powder were used for pot experiments under glasshouse conditions at Mekelle University. One bulk soil sample was collected from a spot at 4 km from the eastern side of the plant. The chemical concentration of major elements Ca, K, Na, Mg, and Mn, and trace elements, Cd, Zn, Cu, Pb, Cr, and Fe in soil and plant parts were determined using an Atomic absorption spectrometer as well as NO3, PO4 and SO4 using UV-spectrometer. The results suggest that the gypsum powder enhances metals and anion content in soil and in crop parts compared to the control sample. The chemical constituents in soil and crop parts showed negligible variation with increasing proportions of gypsum powder. Gypsum loaded Ca, SO4, Mn, and Pb onto the soil, which exhibited higher Mg, Cu, Mo, Cd, NO3, and PO4 but the comparable concentrations of Fe, K, Zn, and Cr in decreasing order. However, a direct relationship was noted in chemical constituent loadings along the pathway: powder-soil-crop in a similar fashion in the three mixes. Factor analyses revealed that wheat parts have a higher accumulation of nutrients than the barley parts with higher content in its growth soil blends. As an extension of this research, the in-situ investigation is recommended to assess the direct impact of the gypsum powder emitted over the soil and crops.

Authors: Escobar A. , Seltmann R. , Broadbent C. , Robinson P. 
Published: August 2021

British Fluorspar Ltd (BFL) operates a lead-fluorite-barite deposit located in the Peak Lake District (Derbyshire, UK) with fluorspar as the main product and lead and barite as by-products. Recent analysis of the CaF2 concentrate showed high values of deleterious elements such as Pb, P, S and As, which affect the quality of the product. Grindability studies showed an overgrinding of material prior to the flotation stage with high liberation of P2O5 mainly to the fluorspar concentrate.
Data obtained from bath flotation test indicated an improvement of lead recovery from 2.33 % to 15.03 %, decreasing Na2S to 100g/t and pH to 9 in the lead oxide circuit and a depression of P2O5 in the fluorspar flotation stage from 87 % to 91 % recovered in the tailings using 200 g/t of CaCl-CuSO4 as “depressant” of phosphates related minerals
