Pulsed currents and magnetic forces of an induction system with a spiral winding and a ferromagnetic shield for processing non-magnetic thin-sheet metal strips in order to create magnetoplastic, electroplastic effects due to eddy currents are studied. Under the strip there is the ferromagnetic shield, and above it – spiral winding. The aim of the work is to develop an analytical method for calculating transients of pulsed currents in an electric circuit with the induction system and a capacitor charged to certain voltage taking into account influence of the ferromagnetic shield to perform investigation of time-varying magnetic field. Electromagnetic parameters of the inductor are determined by computer simulation using the finite element method in the mode of harmonic currents. Current transients in the electric circuit are calculated using known in theoretical electrical engineering mathematical dependences and distribution of current density and magnetic forces in the strip is calculated by the finite element method in the mode of transients. Influence of the ferromagnetic shield on electromagnetic processes in the induction system for the set ranges of strip’s thickness, its electrical conductivity and current frequency is established. Electromagnetic force between the spiral winding and the strip, the current density in the strip, as well as the moments of time at which the current and force have maximum values are studied.

Published: March 2022

The article considers the problems that arise during the operation of high-power photovoltaic solar power plants as part of integrated power systems. The necessity of using energy storage systems to stabilize the operation of solar power plants is described and the calculated mathematical model of their joint operation is given. A study of the operation of a solar power plant with a fixed capacity of photovoltaic modules of 20 MW together with the energy storage system and determined the capacity of batteries needed to stabilize the power supply of electricity to the grid. For the day with the largest volumes of electricity production, in order to fully stabilize the operation of a solar power plant, it is necessary to release 41% of all generated electricity directly into the grid, and other volumes must be accumulated with subsequent discharge. Connecting batteries to a solar power plant allows to reduce the installed capacity of inverters from 18 to 3-5 MW, which reduces the cost of electricity production by 13-16%. According to the data on capital investment and operating costs during the entire period of operation solar power plants together with the energy storage system for the built in 2020 and 2040, the levelized cost of energy, storage and supply into the grid was determined.

Trends in Transcatheter Aortic Valve Implantation in Australia
Authors: Gray Rhys , Sarathy Kiran
Published: March 2022

Aortic valve stenosis is the most common valvular lesion in Australia, with a rising prevalence in line with the ageing population. Recent trials have demonstrated the efficacy of transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement in consecutively lower surgical risk patient cohorts. Despite this, the current indication for TAVI in Australia is for the treatment of severe symptomatic aortic stenosis in patients who are of prohibitive or high surgical risk and ultimately deemed suitable by a heart team. This article summarises the trends in TAVI in Australia over the last 5 years in terms of funding, accreditation and service delivery, as well as advances in technique, technology, patient selection and local outcomes.

Published: March 2022

Purpose: This study aimed to examine the effects of single-task, dual-task and successive physical-cognitive training on fall risk, balance, and gait performances in elderly.Methods: A total of 45 healthy older adults (73.0±4.6 years; 6 male and 39 female) underwent one of three interventions 3 times a week for 4 weeks. Group-1 performed single-task balance and gait exercises. Group-2 performed cognitive activity, balance, and gait exercises simultaneously. Group-3 performed successive cognitive activities and balance and gait exercises. Gait speed under single-task and dual-task conditions, Berg Balance Scale, Timed up and Go test, and Tinetti's Falls Efficacy Scale scores were evaluated before and after 4 weeks of interventions.Results: Gait speed under single-task condition, Timed up and Go Test, and Berg Balance Scale scores were improved in all groups (p<0.05). Gait speed under dual-task condition was improved in Groups-2 and 3 (p<0.05). Group-3 had greater improvement in Berg Balance Scale and Timed up and Go test scores than Group-2. Tinetti's Falls Efficacy Scale was improved in Group-1 and 3 after training while the improvement was greater in Group-3 (p=0.001).Conclusion: The present study suggests that an intervention involving cognitive and physical activities results in greater improvement in gait speed than interventions involving physical activities alone. However, successive physical-cognitive training may be more effective in reducing fear of fall and improving balance skills in elderly.

Published: March 2022

This work aimed to evaluate the effect of ethylene treatment on ripening of 1-MCP treated pear after 6 months of cold storage. Pear treated with gaseous 1-MCP at 625–650 ppb for 24 h at 0 °C was stored at 0 °C for 6 months with normal air, and treated groups were exposed to 100 ppm ethylene at 20 °C for 24 h. After that, samples were kept at 0, 10, and 15 °C for 2 weeks. Stiffness, chlorophyll fluorescence, ethylene and CO2 production of fruit were investigated during 2 weeks. Application of ethylene resumed the ripening of pear after long term storage. The results showed that fruit treated with ethylene achieved more homogeneous surface colour in comparison with non ethylene treated pears. In addition, the ethylene and carbon dioxide production of ethylene treated pears had higher values than that of control. The ethylene treatment could accelerate the softening of pear. Temperature also has significant effect on ripening during storage. This study found that ethylene treatment could accelerate the normal ripening of 1-MCP treated pears.
Getting “clean” from nonsuicidal self-injury: Experiences of addiction on the subreddit r/selfharm

Published: March 2022

Background & Aims

Previous studies have shown that nonsuicidal self-injury (NSSI) has addictive features, and an addiction model of NSSI has been considered. Addictive features have been associated with severity of NSSI and adverse psychological experiences. Yet, there is debate over the extent to which NSSI and substance use disorders (SUDs) are similar experientially.

Methods

To evaluate the extent that people who self-injure experience NSSI like an addiction, we coded the posts of users of the subreddit r/selfharm (n= 500) for each of 11 DSM-5 SUD criteria adapted to NSSI.

Results

A majority (76.8%) of users endorsed at least two adapted SUD criteria in their posts, indicative of mild, moderate, or severe addiction. The most frequently endorsed criteria were urges or cravings (67.6%), escalating severity or tolerance (46.7%), and NSSI that is particularly hazardous. User-level addictive features positively predicted number of methods used for NSSI, number of psychiatric disorders, and particularly hazardous NSSI, but not suicidality. We also observed frequent use of language and concepts common in SUD recovery circles like Alcoholics Anonymous.

Discussion & Conclusion

Our findings support previous work describing the addiction potential of NSSI and associating addictive features with clinical severity. These results suggest that NSSI and SUD may share experiential similarities, which has implications for the treatment of NSSI. We also contribute to a growing body of work that uses social media as a window into the subjective experiences of stigmatized populations.
Q-particles and islands in Sinhala wh- and polar questions
Authors: Romero Maribel , Meertens Erlinde
Published: March 2022

This paper is concerned with the Q-particledəin Sinhala wh-questions and polar questions. Previous approaches propose a two-legged semantic dependency: (i) the lower leg projects a set of alternatives and (ii) the upper leg forms a choice function dependency. The contribution of the present paper is two-fold. First, it presents novel empirical data on complex questions with islands that pose a serious problem for this architecture when applied to polar questions. Second, it develops a new proposal that maintains a common meaning for the Q-particle in the two question types while avoiding this empirical problem. The key insight of the new analysis is to liberalize the upper dependency leg as to pass up a focus value that can later combine with different operators: with the Q-operator in wh-questions and with the squiggle operator in polar questions.

INSTITUTIONALIZATION OF ETHNICITY IN THE CAPITAL CITIES OF THE «NATIONAL REPUBLICS» OF THE RUSSIAN FEDERATION
Authors:   Perm Federal Research Center, Ural Branch Russian Academy of Sciences, Panov Petr
Published: March 2022

The ethnic nature of the constitution of the national republics of the Russian Federation suggests that, to some extent, they are characterized by the institutionalization of ethnicity, which manifests itself at the normative level, in particular, in the structure of government bodies, their representation in public space, in the distribution of political and administrative positions based on ethnicity (power-sharing). Institutionalization of ethnicity occurs not only at the republican level, but also in the authorities of the capital cities of the ethnic republics. In relation to the structure of government bodies and their representation, it is expressed here to a lesser extent, however, the position of the mayor of the capital city plays a significant role in the informal institutionalization of the distribution of political and administrative positions along ethnic lines.

The article deals with issues related to the appointment and election of mayors of the city in the first two post-Soviet decades. Conclusions are drawn, according to which the effectiveness of the work of mayors and popularity among the population did not depend on how a citizen became the head of the city. It is determined that there are almost always opportunities for effective work as the head of the municipality, but it is also necessary to have a number of other factors, including, of course, the activity of citizens and the deputy corps, exerting pressure on the head of the city. Any order of election/appointment of the mayor has the right to exist.

Published: March 2022

Esta pesquisa teve como objetivo investigar as práticas avaliativas realizadas pelos docentes do curso Técnico de Nível Médio. A intenção foi analisar em que medida as práticas contemplam as orientações de avaliação propostas institucionalmente. Essa análise foi realizada a partir do entendimento dos docentes de duas unidades de ensino, localizadas em São Paulo. Para a realização da pesquisa optamos por uma abordagem mista (quantitativa e qualitativa) e seguimos os seguintes procedimentos metodológicos: estudo documental, aplicação de questionários e realização de entrevistas com docentes. O referencial teórico utilizado pautou-se nas diversas formas de entender o processo avaliativo e suas contribuições para a aprendizagem dos alunos, dentre eles: Luckesi (1990,1992,2000), Hoffmann (1999, 2009, 2013), Perrenoud (1999) e Weisz (2002), e em estudos sobre as diferentes concepções de aprendizagem docente, tendo como base as relações entre conhecimento e prática educacional. Constatamos que todos os professores conhecem os documentos da instituição e falam claramente sobre a proposta educacional, entretanto realizam uma avaliação por medida e verificação. Outro ponto a ser ressaltado é que muitos consideram o comprometimento do aluno como principal critério de aprovação.

Significance Statement

Recent research suggests that biomarkers of the TNF pathway (TNFR1 and TNFR2) are associated with worse kidney outcomes. Most of these studies, however, evaluated baseline levels rather than longitudinal changes. In two cohorts (AASK, which enrolled Black people with CKD attributed to hypertension, and VA NEPHRON-D, which enrolled veterans with albuminuric CKD and type 2 diabetes), greater longitudinal increases in serum or plasma TNFR1 and TNFR2 were associated with higher risks of ESKD in AASK and subsequent kidney function decline in VA NEPHRON-D. These associations were independent of baseline biomarker level and kidney function. Longitudinal trajectories in TNFR1 and TNFR2 may ultimately allow improved risk assessment for kidney failure in persons with CKD.

Background

Higher baseline levels of soluble TNF receptors (TNFR1 and TNFR2) have been associated with progressive CKD. Whether longitudinal changes in these biomarkers of inflammation are also associated with worse kidney outcomes has been less studied.

Methods

We evaluated associations of longitudinal changes in TNFR1 and TNFR2 with ESKD in the African American Study of Kidney Disease and Hypertension (AASK; 38% female; 0% diabetes) and kidney function decline (first occurrence of ≥30 ml/min per 1.73 m2 or ≥50% eGFR decline if randomization eGFR ≥60 or <60 ml/min per 1.73 m2, respectively; ESKD) in the Veterans Affairs Nephropathy in Diabetes trial (VA NEPHRON-D; 99% male; 100% diabetes) using Cox models. Biomarkers were measured from samples collected at 0-, 12-, and 24-month visits for AASK (serum) and 0- and 12-month visits for VA NEPHRON-D (plasma). Biomarker slopes (AASK) were estimated using linear mixed-effects models. Covariates included sociodemographic/clinical factors, baseline biomarker level, and kidney function.

Results

There were 129 ESKD events over a median of 7.0 years in AASK (n=418) and 118 kidney function decline events over a median of 1.5 years in VA NEPHRON-D (n=754). In AASK, each 1 SD increase in TNFR1 and TNFR2 slope was associated with 2.98- and 1.87-fold higher risks of ESKD, respectively. In VA NEPHRON-D, each 1 SD increase in TNFR1 and TNFR2 was associated with 3.20- and 1.43-fold higher risks of kidney function decline, respectively.

Conclusions

Among individuals with and without diabetes, longitudinal increases in TNFR1 and TNFR2 were each associated with progressive CKD, independent of initial biomarker level and kidney function.
Mini-Public Replication: Emotions and Deliberation in the Citizens' Initiative Review Redux
Authors: Morrell Michael E. , Johnson Genevieve Fuji , Black Laura W
Published: March 2022

Scholars have increasingly urged researchers to evaluate prior findings through replication studies that can help test, refine, and extend claims made in previous research. We agree that this is an important aspect of social science that deliberative scholarship has underutilized. To help fill this lacunae, we test our previous findings from an analysis of data from Citizen Initiative Reviews (CIRs) in 2016 by replicating our methodology on data from CIRs in 2018. We set out to determine if the patterns we discovered earlier and developed into the Deliberative Procedures Frame theory appeared again in 2018 CIRs. We find repeating across the two sets of data, including consistent levels of enthusiasm, slow rising happiness, and the relationships between certain emotions on the final day and participants’ evaluations of deliberative quality, and these indicate that our theory remains a viable explanation for emotions in mini-public deliberation. We remain confident that the sources of anger and frustration identified in our previous analysis remains correct. On the basis of this replication, we clarify that what we call the Procedures Frame enables the identification of the most likely time points during deliberation when the threat to democratic legitimacy and the risk to quality deliberation will most likely arise and result in expressions of emotion. Finally, our study reinforces how important deliberative design is to the role of emotions in the success of mini-publics.

Authors: John S Craven
Published: March 2022

A review of the Countries with the highest coronavirus death rates in the world was made on February 11, 2022. The world’s average death rate that day was 746. It was not surprising to see the countries with the largest number of deaths having death rates 300- 400% of the world’s average. What was alarming was that the ten countries with the world’s highest death rates had death rates 400-800% of the world’s average and most of them were located in East-Central Europe. This paper focuses on understanding the implications of this.

Authors: Ferguson Scott , Jones Ashley , Borevitz Justin
Published: March 2022

With the advancement of long-read sequencing technologies and associated bioinformatics tools, it has now become possible to de novo assemble complex plant genomes with unrivalled contiguity, completeness and correctness. As read lengths can surpass repeat lengths, the ability to assemble genomes de novo has dramatically improved, whereby complex plant genomes of widely variable sizes and repeat content have highly benefited. Despite these improvements, challenges remain in performing de novo assembly, namely in developing a reliable workflow and in tool choice. Here we present a protocol collection of bioinformatic workflows detailing plant genome assembly using Oxford Nanopore Technologies long-reads with a de novo assembler (Canu), syntenic or Hi-C scaffolding, and RNA and/or gene homology-based annotation. We have developed and tested these protocols on multiple plant genomes. Using these protocols with sufficient coverage of long-reads, a highly contiguous, complete, and correct plant genome can be assembled. These genomes can further genomic research into structural variation among groups, and SNP genotyping and association studies among populations.

The current work is devoted to the study of a sorbent based on organopolymeric cation exchange resin KU-2-8 modified with 6,7-dihydroxy-2-phenyl-4-methylbenzopyrylium chloride for preconcentration and solidphase spectrophotometric determination of Mo(VI) microquantities. The optimal conditions for the preconcentration of Mo(VI) by the proposed sorbent were found to be: pH 5.5, a portion of the sorbent 0.5 g with a grain diameter of 0.43 ÷ 0.50 mm with shaking for 60 min (for static mode) or at a rate of 2 cm3/min with using a column with a 10 mm diameter (for dynamic mode). The calibration graph for solid-phase spectrophotometric determination of Mo(VI) after its sorption preconcentration using the modified sorbent in static mode is linear in the concentration range of 0.15-4.24 mg/dm3, and the values of the limit of detection and limit of determination are 0.05 and 0.15 mg/dm3 respectively. The proposed method was tested in the analysis of a sample of peas with a relative standard deviation no more than 4.9 %.

Premature infant formula powder (PIFP) contains essential nutrients, such as protein and LC-PUFAs in which inadequate quantities of them may restrict the development of premature infants. The aim of this study was to propose a quantitative analysis for evaluating these nutrients in PIFP. To achieve this purpose, an integrated methodology was developed by combining attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR) with the chemometrics. ATR-FTIR was utilized to obtain the PIFP spectra in the wavenumber range of 4000-400 cm-1. Principal component analysis (PCA) was employed to perform exploratory analysis of the spectra. Partial least square regression (PLSR) and principal component regression (PCR) models were established for normal spectra, first, and second derivatives to quantitatively determine the protein and LC-PUFAs. The results showed that the PLSR model provided a better prediction than the PCR model with the coefficient of determinations (R2) of 0.992 and 0.983 for training and validation, respectively. It also offers the best prediction for the PLSR model of protein considering the parameters such as R2 (normal spectra) (Cal: 0.995, Val: 0.981). The results revealed that a combination of the ATR-FTIR spectroscopy and the chemometrics models creates a rapid, inexpensive, and non-destructive method for the quantitative analysis of PIFP.

Objective: To investigate the prevalence of morphological and attachment variations of the maxillary labial frenum (MLF) and associated factors in preschool children. Study Design: A cross-sectional study was conducted with 1,313 children aged between zero and five years of age attending public nurseries in the city of Canoas in southern Brazil. Data were collected through a questionnaire addressing demographic, socioeconomic, and behavioral characteristics and a clinical examination of the MLF. Assessments of MLF morphology and attachment were based on the classification systems proposed by Sewerin and Mirko et al., respectively. Results: The most prevalent patterns were simple MLF (63.8%) and gingival attachment (51.1%). Morphological abnormalities were found in 21.6% of the preschoolers and 25.4% exhibited abnormal frenal attachment. Abnormalities in MLF morphology were more prevalent among girls (p = 0.003) and a significant reduction was found with the increase in age (p < 0.001). Attachment abnormalities were significantly more prevalent among girls (p < 0.001), the white ethnic group (p = 0.005), and children who used a pacifier (p = 0.007) and also reduced significantly with the increase in age (p < 0.001). Conclusion: Demographic and behavioral characteristics were associated with MLF morphology and attachment. The reduction in the prevalence of the outcomes with the increase in age suggests that surgical interventions in the first years of life may constitute overtreatment.

The article analyzes the unique properties of arbitration proceedings that integrate civil and criminal types of processes. Implemented in the APC the possibility of joint consideration in arbitration proceedings of claims for bringing to administrative responsibility together with other requirements, in the author’s opinion, proves the fundamental possibility of joint consideration in this legal proceeding of an economic dispute and a criminal case arising from it, which will exclude the possibility of obtaining in the framework of criminal proceedings a diﬀerent result of resolving an economic dispute than that which can be achieved by applying to an arbitration court.
