Comparing Coverage of Black Protests in Mainstream Newswires and Black Newspapers
Authors: Oliver Pamela Elaine , Lim Chaeyoon , Milewski Anna O. , Gaede Erin
Published: May 2024

This working paper compares mainstream newswires and Black newspapers in their coverage of Black protest events 1994-2010 with an emphasis on the differences between sources in attention to different kinds of issues. Perceptions of what Black collection is “about” vary by source. There is low overlap between sources. Even though many more events were identified in Black newspapers than newswires and the focus is on Black protest events, 61% of the events identified in the newswires were not mentioned in the Black newspapers. The large majority (70%) of events were reported only once in one news source. Our focus is not on overall comprehensiveness, but on selection and attention: what issues and event types are different sources most interested in. Besides comparing newswires to Black newspapers, we also compare Black newspaper coverage of events in the newspaper’s state to coverage of events elsewhere. All source types gave significant attention to criminal legal issues, especially issues of police violence. All source types give more coverage to larger events, to events that are parts of larger episodes of contention, to events involving more police action, and to events spanning multiple days. Newswires and non-local Black newspaper coverage gives more attention to violent events and to Black history and solidarity events. White-centric newswires give more attention to White-centric issues (affirmative action, Confederate symbols, White supremacist groups) and to inter-group violence involving Black people. Local Black newspaper coverage gives much more attention to issues with a state or local focus and to worker issues. Non-local Black newspaper coverage gives more attention to Black involvement in national issues. We discuss the importance of these differences for the differing collective memories of Black and White Americans and the importance of incorporating the Black gaze into research on Black movements in the US.

Published: May 2024

This study aims to examine the effect of leverage, audit quality, and capital intensity on tax avoidance. The method used in this research is Cash Effective Taz Rate (CETR). This method is used to measure tax avoidance. Tax avoidance is a practice carried out by companies using various methods in order to avoid tax obligations. The population used in this study are companies in the Mining Sector for the 2017-2019 period listed on the Indonesia Stock Exchange. Purposive sampling was used in sampling. The number of companies that meet the criteria is 16 companies. This study uses multiple linear regression analysis and T statistical test to answer the hypothesis using SPSS version 25. The results showed that capital intensity has an impact on tax avoidance. Leverage has no impact on the tax avoidance variable and audit quality has no impact on the tax avoidance variable. When viewed from the coefficient of determination indicates that the leverage, audit quality and capital intensity variables explain only about 26.1% of the variation in the tax avoidance variable, while the remaining 73.9% can be explained by other variables.

Published: May 2024

Leguminous crops play an important role in providing the population with high-protein products and farm animals with feed. The correct selection and distribution of species and varieties of these crops in accordance with soil and climatic conditions have a significant impact on their productivity.

   The purpose of the current work was to estimate productivity of green mass, hay, grain, as well as the degree of development of traits that affect the productivity formation of peas, chickpeas, lentils, spring vetch, and fodder beans when grown in the southern forest-steppe of the Republic of Bashkortostan.

   The study was carried out in 2021–2023. Contrasting weather conditions made it possible to comprehensively estimate the material being studied. The objects of the study were the varieties of five types of leguminous crops ‘Pamyati Popova’ (peas), ‘Sokol’ (chickpeas), ‘Nevesta’ (lentils), ‘Uzunovskaya 8’ (spring vetch), ‘Kalor’ (fodder beans). The trials were carried out in accordance with the Methodology of State Variety Testing (2019). As a result of the research, there were identified leguminous crops that were the most adaptive in a number of parameters for cultivation in the Southern Urals of the Republic of Bashkortostan, namely peas, chickpeas, lentils with 65.7 ± 9.7–70.7 ± 9.4 days of a vegetation period; peas with a maximum growth rate before the budding phase; peas, chickpeas, spring vetch, fodder beans with the most developed root system; peas and spring vetch with the largest number (223.3±13.3 – 236.0±17.1 pieces, respectively) and weight (0.39±0.04 – 0.45±0.07 g, respectively) of nodules per 10 plants. The maximum productivity of green mass (7.41–7.47 t/ha) and hay (1.87–1.89 t/ha) was obtained from peas and spring vetch. The maximum productivity of seeds (1.48–1.51 t/ha) was from peas and chickpeas. Thus, there has been recommended to expand pea crops, including chickpeas and lentils in the crop rotation, and restoring spring vetch crops. To achieve consistently high yields of these leguminous crops, it is necessary to sow them in the early stages with seeds of higher reproductions, treated before sowing with appropriate disinfectants and microfertilizers.

Published: May 2024

There has been presented a three-year estimation of winter wheat samples according to adaptability indicators, the trait ‘productivity’, ‘winter resistance’, ‘1000-grain weight’, and ‘number of productive stems per m2’.

   The purpose of the study was to estimate the adaptive potential of winter common wheat varieties in the forest-steppe of Western Siberia at different sowing dates.

   The study was conducted in the laboratory for field crop breeding, seed production and cultivation technologies based on SibRIPCB, the branch of Institute of Cytology and Genetics, SB RAS (Novosibirsk region) in 2018–2022. The objects of study were 5 winter common wheat varieties developed by the SibRIPCB, a branch of the Institute of Cytology and Genetics SB RAS. Sowing was carried out in three periods (the first was in August 20, the second was in September 1 and the third was in September 10) with an SSFC-7 seeder in 5 repetitions, the recording plot area was 10 m², the placement of the plots was randomized, the crops were laid in weedfree fallow. As a result, there was established that, according to the trait ‘productivity’, the varieties ‘Novosibirskaya 2’ (bi = 1.42; δd² = 0.08) and ‘Novosibirskaya 3’ (bi = 1.35; δd² = 0.08) combined ecological adaptability and stability. The variety ‘Novosibirskaya 3’ also combined adaptability and stability according to the trait ‘number of productive stems per m2’ (bi = 1.09; δd² = 468.94). The winter variety ‘Krasnoobskaya’ is capable of consistently giving high yields ((Ymax+Ymin)/2 = 4.92; (Sc = 3.42); Hom = 26.2) and maintaining the density of productive stems ((Ymin–Ymax) = -280; Sc = 280.8; (Ymin+Ymax)/2 = 513; Hom = 8.9) at different sowing dates. The variety ‘Pamyati Chekurova’ is responsive to improvements in environmental conditions according to the trait ‘productivity’ (bi = 1.10; KM = 2.20), ‘winter resistance’ (bi = 1.53; KM = 2.72), ‘number of productive stems per m2’ (bi = 1.22; KM = 2.2).

Published: May 2024

The purpose of the study was to identify the effect of quantitative traits on grain productivity of maize hybrids depending on moisture availability.

   The study was carried out on the breeding field of the laboratory for maize breeding and seed production of the FSBSI “ARC “Donskoy” in 2020–2023. The soil of the experimental plot was ordinary blackearth, with a humus layer thickness of 140 cm. The climate is characterized by aridity with unstable moisture. The years of the study were contrasting in temperature and moisture availability (HTC 0.49–0.83). Due to the uneven distribution of precipitation during a vegetation period of maize, the temperature regime through the months and moisture availability had even greater differences (HTC 0.11–2.28). The objects of research were 96 maize hybrids. The main method for developing hybrids was an interline hybridization. There has been identified a stable correlation between grain productivity and quantitative traits in each of the four years of study, when ‘one ear weight’ was r = 0.34±0.09 – 0.64±0.08 and ‘number of grains in a ear row’ was r = 0.35±0.09–0.58±0.08. The specific climatic conditions of some years of the study (one year out of four) influenced the lack of correlation between amount of productivity and quantitative traits with ‘number of ears per plant’ (r = 0.11 ± 0.10 in 2022), ‘number of grains per ear’ (r = 0.01±0.10 in 2023), ‘grain yield during threshing (r = 0.04±0.10 in 2023). The correlation between productivity and traits was subject to even greater variability depending on weather conditions with ‘ear attachment height’ (r = 0.01±0.10–0.40±0.09), ‘plant height’ (r = 0.16±0.10–0.38±0.09), ‘ear diameter’ (r = -0.02±0.10–0.43±0.09), ‘1000-grain weight’ (r = -0.14±0.10–0.45±0.09). In all years of the study, there were no correlation between productivity and such traits as ‘number of grain rows’ (r = -0.27±0.09–0.17±0.10) and ‘ear length’ (r = 0.01±0.10–0.29±0.09).

The current paper has presented the study results conducted on the experimental plot of the Falenskaya breeding station of the branch of the FSBI FANC of the North-East in 2021–2023.

   The purpose of the study was to evaluate the collection hulled oat varieties according to grain productivity and adaptability parameters in the soil and climatic conditions of the Kirov region.

   The materials for the study were 9 collection oat varieties and the standard variety ‘Krechet’. According to the trait ‘productivity’, there have been estimated adaptability parameters. During the testing years, the studied variety samples differed significantly in productivity variability (V = 16.8–30.0 %). The factor ‘year’ had the greatest effect on the formation of oat yields (90.3 %). In the arid year of 2021, the varieties’ productivity was low (276–401 g/m2), with a negative index of environmental conditions (Ij = -163), in the most favorable year of 2022, it was 463–682 g/m2 and Ij = 104, respectively. The variety samples ‘k-3967 0144’ (-190 g/m2) and ‘15584 Mutant 258’ (-214 g/m2) were characterized by high stress resistance. High genetic flexibility of mean productivity under contrasting conditions was established in the variety samples ‘15472 Sumphony’ (504 g/m2), ‘k-3967 0144’ (496 g/m2) and ‘15340 Uran’ (487 g/m2). There have been identified such gene sources as plastic ‘k-3967 0144’, ‘15472 Sumphony’, ‘15340 Uran’, ‘k-3951 0146’, ‘k-3954 0149’ (IEP = 1.13–1.0), and with high stability of the trait ‘productivity’ ‘k-3967 0144’, ‘15584 Mutant 258’, ‘k-3954 0149’ (SF = 1.47–1.78). Low variability and high homeostaticity were found in the variety samples ‘k-3967 0144’, ‘15584 Mutant 258’, ‘k-3954 0149’ (V = 16.8–22.8 %; Hom = 31.31–20.75) with a high stability index (Is = 5.95–4.38). The adaptability coefficient has confirmed the high adaptability of variety samples ‘k-3967 0144’, ‘15472 Sumphony’ and ‘15340 Uran’ (KA =112.3–108 %). In adaptive breeding for further work, the varieties ‘k-3967 0144’, ‘15584 Mutant 258’, ‘k-3954 0149’, ‘15472 Sumphony’, ‘15340 Uran’ are of great interest, since they are the most adaptive in terms of the sum of ranks. Based on a comprehensive estimation of productivity and adaptability parameters, ‘k-3967 0144’ was recognized as the best variety sample, which can give a large mean productivity (526 g/m2) in changing weather conditions.

Published: May 2024

The purpose of the current study was to conduct an environmental testing and give a comprehensive estimation of the adaptability parameters of modern grain sorghum varieties developed by the FSBSI “ARC “Donskoy”. Weather conditions during the years of study were different, which made it possible to estimate varieties under contrasting cultivation conditions.

   The year’s conditions index was the highest in 2019 and 2023 (+0.76 and +1.03), and the lowest (-1.21) in the acutely arid year of 2020. The main effect on the productivity formation of the grain sorghum varieties was made by the conditions of the year (49.8 %) and the minor effect was made by the genotype of the variety (31.0 %). The varieties ‘Ataman’, ‘Zernogradskoe 88’, ‘Luchistoe’, ‘Zernogradskoe 53’ were found to be more productive (> 4.6 t/ha) and have a higher adaptability coefficient (108.8–117.2 %). Intensive samples (bi > 1) were ‘Zernogradskoe 53’, ‘Ataman’, ‘Luchistoe’, ‘Zernogradskoe 88’. Extensive varieties (bi < 1) were ‘Orlovskoe’, ‘Velikan’ and ‘Krymbel’ (st.). The varieties ‘Luchistoe’, ‘Ataman’,’ Zernogradskoe 88’ (S2d = 0.02–0.04) had high stability indicators, and the varieties ‘Ataman’, ‘Luchistoe’, ‘Zernogradskoe 88’, ‘Zernogradskoe 53’ had high overall adaptive capacity (TAC). The maximum indicators (115–131 %) of the stability level were established in the varieties ‘Ataman’, ‘Luchistoe’, ‘Zernogradskoe 88’. The rating estimation of adaptability parameters has shown that the early ripening intensive varieties ‘Ataman’ (68 points), ‘Luchistoe’ (67 points) and ‘Zernogradskoye 88’ (61 points) are the best and the most suitable ones for cultivation in the Donbass.

Published: May 2024

The purpose of the current study was to estimate the potential of soybean varieties of various ecological and geographical groups according to the trait ‘seed weight per plant’ and to identify varieties with high adaptability to the conditions of the Ryazan region.

   The objects of research were 33 soybean samples from the world collection, which differed in morphological and biological characteristics. The soybean variety ‘Sibiriada’ (Russia), zoned for the Central region, was taken as the standard variety. Field trials were carried out on dark gray forest soil at the Institute of Seed production and Agrotechnologies, branch of the Federal Budgetary Scientific Institution “FRAEC VIM”, located in the Ryazan region in 2021–2023. In order to characterize the adaptability parameters, there have been used such indicators as homeostatic index (Hom), coefficient of variation (CV), stability factor (SF); range of the indicator ‘seed weight per plant’ (d), standard deviation (σ); adaptability coefficient (AC); stability level indicator (SLI) and stress resistance (Ymin–Ymax), calculated using appropriate methods. There has been established that according to the trait ‘seed weight per plant’ the varieties ‘Georgiya’, ‘Snezhana’ and ‘Chera 1’ (Russia) had the lowest value of variation with Cv,%≤20.0. It was found that the varieties ‘Georgiya’ and ‘Snezhana’ (Russia) were the most stable to external environmental changes. This was evidenced by the lowest values of the coefficient of variation (Cv = 12.9 and Cv = 14.0 %, respectively) and high homeostaticity (Hom = 31.3 and Hom =28.9). The greatest variability and low homeostaticity were found in the soybean varieties ‘Vereteyka’ (Hom = 1.69, Cv = 58.4 %) and ‘Elena’ (Hom = 2.17, Cv = 50.3 %), which characterized the low adaptability of these varieties to the conditions of the Ryazan region. As a result of the estimation of the genotypes studied in the trial according to the triat ‘seed weight per plant’, it was established that the varieties ‘Georgia’ (Russia), ‘Snezhana’ (Russia), ‘Chera 1’ (Russia), ‘Garmoniya’ (Russia) were of great breeding value for improving adaptability and stability in the forest-steppe agroclimatic zone of the Ryazan region.

Another Look: American Catholics and the Quest for Equality in the Civil War Era
Authors: Duncan Jason
Published: May 2024

Robert Emmett Curran’s masterful treatment of American Catholicism in the Civil War era is the first comprehensive history of Roman Catholics in the North and South before, during, and after the war. Curran provides an in-depth look at how the momentous developments of these decades affected the entire Catholic community, including Black and indigenous Americans. He also explores the ways that Catholics contributed to the reshaping of a nation that was testing the fundamental proposition of equality set down by its founders. Ultimately, Curran concludes, the revolution that the war touched off remained unfinished, indeed was turned backward, in no small part by Catholics who marred their pursuit of equality with a truncated vision of who deserved to share in its realization.

Authors: Samarin O. D. , Kirushok D. A.
Published: May 2024

The relevance of the study is related to the need to ensure maximum reduction of energy consumption while ensuring the calculated parameters of the indoor climate in buildings under the Law of the Russian Federation “On Energy Saving...” and the updated version of SP 131. The purpose of the study is to obtain an approximate analytical expression of this dependence, which makes it possible to additionally confirm the results of field and numerical experiments previously performed by the authors for this flow treatment scheme. The objective of the study is to build a simplified mathematical model of the processes of changing the heat and humidity state of the air in the recuperator, identify the main factors affecting the increasing multiplier to the coefficient of temperature efficiency of the device and obtain the necessary numerical coefficients in formulas linking the desired and initial parameters. The general equation of thermal balance and heat transfer for the heat exchanger as a whole is used, including the integral characteristics of the apparatus in a dimensionless form, as well as standard techniques of algebraic transformations. An approximate analytical expression is obtained for an increasing multiplier to the coefficient of thermal efficiency of the recuperator taking into account the additional cooling of the inflow due to the heat consumption for evaporation. It is shown that the general structure of this ratio coincides with the one found by the authors earlier by processing the results of numerical modeling of a two-dimensional temperature field in a heat exchanger, taking into account experimental data on the amount of moisture carried away, which confirms their correctness and reliability.

Published: May 2024

Significant recent research on the German Right between 1918 and 1933 calls into question received narratives of Weimar political history. The German Right in the Weimar Republic examines the role that the German Right played in the destabilization and overthrow of the Weimar Republic, with particular emphasis on the political and organizational history of Rightist groups as well as on the many permutations of right-wing ideology during the period. In particular, antisemitism and the so-called “Jewish Question” played a prominent role in the self-definition and politics of the right-wing groups and ideologies explored by the contributors to this volume.
NIGHTTIME BREASTFEEDING
Authors: Tomori Cecília
Published: May 2024

Nighttime for many new parents in the United States is fraught with the intense challenges of learning to breastfeed and helping their babies sleep so they can get rest themselves. Through careful ethnographic study of the dilemmas raised by nighttime breastfeeding, and their examination in the context of anthropological, historical, and feminist studies, this volume unravels the cultural tensions that underlie these difficulties. As parents negotiate these dilemmas, they not only confront conflicting medical guidelines about breastfeeding and solitary infant sleep, but also larger questions about cultural and moral expectations for children and parents, and their relationship with one another.

Published: May 2024

STK39 es un gen que codifica para la serina/treonina quinasa, localizado en el cromosoma 2q24.3. Conocido también por sus homólogos SPAK/PASK/STE20-SPS1, se encuentra abundantemente expresado en el cerebro con funciones en la diferenciación celular, la transformación y proliferación celular. En la literatura se han encontrado diversos artículos donde se muestra una asociación de dicho gen con neoplasias renales y hepáticas fundamentalmente. Usando los términos autismo, genética, STK39 y psicosis, se ha realizado una búsqueda en los periodos comprendidos desde 2018 a 2023 en PubMed. El caso clínico relatado a continuación versa sobre unas hermanas mellizas, portadoras de dicho gen, con el diagnóstico de trastorno del espectro del autismo (TEA) y discapacidad intelectual, así como comorbilidad orgánica para ambas. En una de ellas, tal y como se presenta, se desarrolla un episodio psicótico a los 12 años de edad. A pesar de que el gen STK39 no está descrito como uno de los genes más frecuentemente responsable de la expresión de TEA, un estudio en la literatura apoya que el STK39 sería un nuevo gen candidato para el TEA.

The atomic force microscope (AFM) enables the measurement of sample surfaces at the nanoscale. Reference standards with calibration gratings are used for the adjustment and verification of AFM measurement devices. Thus far, there are no guidelines or guides available in the field of atomic force microscopy that analyze the influence of input parameters on the quality of measurement results, nor has the measurement uncertainty of the results been estimated. Given the complex functional relationship between input and output variables, which cannot always be explicitly expressed, one of the primary challenges is how to evaluate the measurement uncertainty of the results. The measurement uncertainty of the calibration grating step height on the AFM reference standard was evaluated using the Monte Carlo simulation method. The measurements within this study were conducted using a commercial, industrial atomic force microscope.

Published: May 2024

Poly(vinyl alcohol) (PVA) and poly(ethylene) oxide (PEO) are widely used water-soluble and biodegradable polymers that possesses high biocompatibility. In this work PVA/PEO blends were prepared via solution casting method, where the solvent was water. After drying, samples were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). Since DSC could not confirm the possible intermolecular interaction between PVA and PEO, infrared spectroscopy with Fourier transform (FT-IR) was utilized. Finally, the TG analysis revealed that degradation of PVA/PEO blends proceeds through tree stages, similar as neat PVA. Contrary, neat PEO thermally degrade through only one stage showing better thermal stability in comparison to PVA.

Assessing Robotic Process Automation (RPA) projects is challenging, especially for small and medium-sized enterprises (SMEs) with limited resources. The most common approach, cost-benefit analysis, measures the financial success of a project, but it does not capture all RPA benefits, which can lead to erroneous decisions about starting, continuing, delaying, or stopping an RPA project. This research presents a novel RPA project assessment model that combines a benefits approach with the balanced scorecard (BSC) framework. The model identifies RPA benefits from the scientific literature and classifies them into four BSC indicators: financial, business process improvement, customer satisfaction, and learning and development. SMEs can easily use the model by comparing expected and actual benefits to make quick and holistic decisions. The model's simplicity, ease of use, and ability to reveal both monetary and non-monetary RPA benefits make it a valuable tool for SMEs.

INTERPELAÇÕES EPISTEMOLÓGICAS: NOTAS SOBRE O ENSINO DA CIÊNCIA MODERNA NA GRADUAÇÃO DE UMA UNIVERSIDADE PÚBLICA
Authors: Maurício de Lima Vinícius , Mendes de Vasconcellos Bruna , Guidi Itokazu Anastasia
Published: May 2024

Com a “Lei de Cotas”, o perfil de discentes do Ensino Superior no Brasil tem se tornado mais diverso. Mas o ensino da ciência moderna ainda privilegia a visão de mundo ocidental. Assim, questionamos como poderíamos na Universidade Federal do ABC (UFABC), onde lecionamos, diversificar o ensino de epistemologia. Pressupomos que, ao propor uma ementa com discussões contemporâneas sobre colonialidade, raça e gênero no fazer científico, conseguiríamos tensionar currículos mais tradicionais, buscando uma descolonização de saberes (KILOMBA, 2019), o que tivemos como objetivo refletir com discentes e docentes. Relatamos e analisamos nossa experiência na disciplina “Bases Epistemológicas da Ciência Moderna”, ministrada para discentes de cursos de graduação interdisciplinares. Da proposta de um programa diversificado à realização de dinâmicas em aula e de uma avaliação plural, notamos que parte dos/das discentes pôde refletir criticamente sobre a produção do conhecimento científico. Também, observamos como as desigualdades socioeconômicas entre discentes impactam na democratização da ciência. Encerramos relatando ecos dessa perspectiva epistemológica insurgente na própria instituição e nos debates entre docentes sobre a disciplina.
Presentación del Dossier: Las luchas feministas y de las mujeres como potencia de transformación. Caminos recorridos y horizontes políticos.

Escribimos cuando han transcurrido casi 18 meses –¡un año y medio!– de esta era pandémica-capitalista-sanitizante. Es estimulante porque los textos que aquí se conjugan constituyen un contraste y un recordatorio: había vida en lucha entonces, ha habido vida en medio de esta crónica superposición de crisis e incertidumbres y seguiremos empujando cuando todo esto se estabilice, quizá volviéndose crónico. De hecho, creemos que sin los diagnósticos, vocabularios y redes de prácticas feministas que vienen tomando fuerza los últimos años no estaríamos atravesando la pandemia del mismo modo. Hoy, cuando extrañamos tanto la vida no confinada ni reiteradamente amenazada de “contagio”, extrañamos y no olvidamos a las compañeras que no alcanzaron a sobrevivir a este período inédito que estamos, de muchas maneras, resistiendo mientras ensayamos modos de subvertirlo.
Supplementation of feline hemoplasmosis treatment protocol with Gamavit and Phosprenyl increases the effectiveness of anemia correction: a retrospective analysis
Authors: Savoyskaya Svetlana
Published: May 2024

This study includes clinical data collected from 2016 to 2023. In total, hemoplasmosis was detected in 102 cats (63 females and 39 males) aged from 5 months to 8 years. Of these, 34 cats were diagnosed with a severe form of the disease, and 68 with a mild one. In cats with severe hemoplasmosis, in 45 % of cases, the disease was complicated by chronic renal failure. Also, 5 % of them were chronic carriers of toxoplasmas. Most of the animals were taken from shelters, or were homeless.
One of the leading clinical signs of hemoplasmosis is anemia, which develops as a result of mass hemolysis of infected red blood cells.
The aim of this work was to eliminate anemia and accelerate the normalization of hematopoiesis in cats with hemoplasmosis.
For the treatment of 45 animals (control group), a standard therapy regimen was used, which included antibiotics and glucocorticoids, whereas for therapy regimen of remaining 57 cats (experimental group) Gamavit and Phosprenyl were added. Using this therapeutic scheme, early relief of anemia, stimulation of erythropoiesis, restoration of blood formula and normalization of liver function were noted as well as acceleration of clinical recovery of sick animals which occurred faster by 4…5 days.

Published: May 2024

The future space experiment «Sun-Terahertz» is aimed at studying the Sun in the unexplored terahertz range, obtaining new data on the terahertz radiation of the Sun, solar active regions and solar flares. The scientific equipment being developed is a set of eight detectors sensitive to radiation of various frequencies in the range 0.4–12.0 THz. The Golay cell optoacoustic receiver was used as a sensitive element of the detectors. This paper examines the problem of changing the sensitivity of receivers of this type when their own temperature changes (temperature effect). Using a test bench based on a single-channel model of scientific equipment and a black body simulator, the linear section of the temperature dependence of the receiver was determined. A method for compensating the temperature effect of optoacoustic converters Golay cell has been developed and the results of its testing on a test bench are presented. This technique will be useful in the development of scientific equipment based on Golay cells, the operation of which is expected under conditions of temperature changes in the surrounding space.
Triple point of carbon dioxide: using a new calibration point of the International Temperature Scale ITS-90
Authors: Beketov N. A.
Published: May 2024

One of the important tasks of improving the International Temperature Scale ITS-90 is considered – the substitution of the fixed point of mercury (Hg) in connection with the ratification of the Minamata Convention and restrictions on the extraction, use and transportation of mercury. Reported results of experimental calibration of long-stem standard platinum resistance thermometers using a new calibration point from the list of secondary fixed points of the International Temperature Scale ITS-90. A method has been developed to realize the triple point of carbon dioxide (CO2) using liquid nitrogen. The method reduced the preparation time of the cell from 60 to 30 minutes and increased the duration of melting plateau from 10 to 40 hours. Presented results of two calibrations cases: using the fixed-point of Hg; using the triple point of CO2 instead of fixed-point Hg. Described methods to evaluate propagation of calibration uncertainty based on the fixed-point sensitivity coefficients. The fixed-points sensitivity coefficients for two subranges of standard platinum resistance thermometers calibration are analyzed and it is shown that the calibration uncertainty using the triple point of CO2 is reduced by half in the range of –189.3442...+ 0.01 °C and by 1.5 times in the range of –60...+ 60 °C. The results confirm the possibility and prospects of using the CO2 triple point as a new calibration point to substitute the fixed-point Hg.
Analysis of the instability of the characteristics of a standard platinum resistance thermometer in the interval between verifications and a method for reducing the measurement error
Authors: Moiseeva N. P.
Published: May 2024

The standard platinum resistance thermometer is currently the most accurate contact temperature sensor. One of the most important characteristics of its error is the instability of resistance during the interval between calibrations. In this work, the task was set to analyze the data from periodic calibration of 27 thermometers performed at the D. I. Mendeleev Institute for metrology for several years. Based on the analysis, it was concluded that the instability of the resistance of thermometers at the triple point of water for most thermometers exceeds ±0.002 °C, sometimes reaching several hundredths of a degree. The work analyzes the reasons for the instability of resistance, as well as the instability of the relative resistance of thermometers. Based on data analysis of the thermometer error at the temperatures between calibration points and graphs of changes in the interpolation function during the interval between the calibrations in the entire measurement range, it was shown that the error associated with the instability of the thermometer can be reduced from hundredths to thousandths of a degree when used as a measured parameter relative resistance of the thermometer. It is proposed to include in the regulatory documents on the verification methods of Standard platinum resistance thermometers an additional periodic calibration of the thermometers at the triple point of water.

The problem of reconstructing the distribution of permittivity and magnetic permeability over the thickness (profile) of non-metallic coatings is relevant in connection with the increasing role of modern methods of radio wave non-destructive testing for assessing the quality of various types of materials and products. Using radio wave methods, the distribution of permittivity and magnetic permeability over layers of multilayer dielectric and magnetodielectric coatings on a metal substrate was reconstructed. The resolution of the method of surface electromagnetic waves in terms of permittivity and magnetic permeability has been studied – the difference between the values of the permittivity and magnetic permeability of adjacent layers of multilayer dielectric and magnetodielectric coatings, respectively. An original method has been developed for assessing the maximum resolution of the surface electromagnetic wave method depending on the electrophysical parameters of the coating layers, the number and bandwidth of measurements, as well as the standard deviation of noise affecting the result of measuring the field attenuation coefficients of the surface wave. The structure of the measuring complex that implements the developed methodology is given. The results of numerical and full-scale experiments to assess the resolution limits of the permittivity and magnetic permeability of layers of two-layer coatings of various types are presented. Numerical experiments were carried out on a sample of a twolayer radio-absorbing coating, and full-scale experiments were carried out on a sample of a two-layer dielectric coating based on Ro4003C and Arlon25N materials. The results of numerical and natural experiments were found to coincide, which confirms the adequacy of the developed methodology. With a measurement bandwidth of 9.0–12.5 GHz and a standard noise deviation of 0.002, the resolution limit for the permittivity and magnetic permeability of layers is 0.25–0.50 %. The proposed technique can be in demand in various science-intensive fields when assessing the electrical parameters of multilayer coatings during efficiency tests.
