Published: September 2021

Objectives

To assess fetal cardiac structures using HDlive Flow Silhouette with spatiotemporal image correlation (STIC) at 12 to 14 + 6 weeks of gestation, and verify the feasibility of obtaining five cardiac views in the late first and early second trimesters of pregnancy. The fetal cardiac shape and the aspect of the descending aorta were also evaluated.

Methods

Eighty normal fetuses at 12 to 14 + 6 weeks of gestation were studied using trans-abdominal HDlive Flow Silhouette with STIC to assess the feasibility of five fetal cardiac views (frontal, spatial three-vessel, panoramic, posterior, and right lateral views). Target structures in each cardiac view were evaluated. ‘Good’ was assigned when all structures were noted, ‘Fair’ when only one structure was missed, and ‘Poor’ when two and more structures could not be detected. Frequencies of an elongated heart and those of a tortuous descending aorta were counted.

Results

Forty-nine fetuses were effectively included in the analysis. Success rates of ‘Good’ and ‘Fair’ were significantly higher with spatial three-vessel (p<0.01) and panoramic views (p<0.05). Frequencies of “Elongated heart”, “Elongated left ventricle”, and “Spherical heart” were 12.2, 6.2, and 81.6%, respectively. Frequencies of “Tortuous descending aorta” and “Straight descending aorta” were 12.2 and 87.8%, respectively.

Conclusions

The feasibility of obtaining fetal five cardiac views using HDlive Flow Silhouette with STIC is good, and this technique provides useful information for evaluating fetal cardiac structures in the late first and early second trimesters of pregnancy.
Application of sequencing batch biofilm reactor (SBBR) to recycled paper mill effluent treatment
Authors: Chen Shuangshuang , Lei Lirong , Li Youming
Published: September 2021

Paper mill effluent has been characterized as recalcitrant because of containing lignin and its derivatives. Since biofilm system exhibits a notable potential for the removal of recalcitrant contaminants, a sequencing batch biofilm reactor (SBBR) was employed to treat coagulated recycled paper mill effluent in this study. The results indicated that the SBBR removed 91.3 % of chemical oxygen demand (COD), whilst total suspended solid (TSS) and color removal reached 83.1 % and 71.0 %, respectively. The microbial analysis suggested that three typical heterotrophic phyla, Proteobacteria, Bacteroidetes and Acidobacteria are dominant bacteria and reflected the removal of recalcitrant contaminants. The COD removal rate of SBBR is evidently superior to conventional activated sludge process due to high sludge concentration as well as long sludge retention time (SRT). Whilst the problem of sludge bulking can be successfully avoided, the blockage of reactor caused by TSS accumulation and microbial growth deserve further investigation.

Published: September 2021

Objectives

The aim of this research was to investigate whether sinapic acid (SA) can alleviate oxidative damage, apoptosis, and inflammation in I/R induced renal injury.

Methods

A total of 24 male rats were randomly separated into four groups as six rats in each group. Group 1 (Sham), Group 2 (I/R), Group 3 (I/R + SA, 10 mg/kg), Group 4 (I/R + SA, 20 mg/kg). In order to evaluate kidney function serum BUN, Cr, and AST were measured in an autoanalyzer. SOD, GSH-Px, MDA, PC and NO oxidative stress parameters were measured with spectrophotometric methods and TNF-α, IL-1β, IL-6, KIM-1 and NGAL parameters were measured with the ELISA method. In addition, H&E method and immunohistochemical examinations were performed for histological evaluations of kidney tissue.

Results

SA significantly decreases the increase in kidney damage, inflammation, oxidative stress, cell death and restore the decrease in antioxidant enzyme activities (p<0.05). Pre-treatment of the rats with SA reduces kidney dysfunction and morphological changes.

Conclusions

The development of oxidative stress and lipid peroxidation seems to be the leading factors that accelerate inflammation and cell death during renal IRI. The antioxidant, anti-inflammatory, and anti-apoptotic features of SA displayed a renoprotective effect.

This study aims to determine the effects of essential oils ofOriganum dubium(DUB), Origanum vulgaresubsp.hirtum(HIR), andLavandula angustifolia(LAV) on lipid profiles and liver biomarkers in athletes. Thirty-four trained athletes were randomly assigned to one of three experimental groups or the control group (CON). The concentrations of serum lipids and liver biomarkers were assessed before and after the 14-day essential oil intervention. Gas chromatography-mass spectrometry analysis showed 68.0 and 82.1% carvacrol in DUB and HIR, respectively, and 34.50% linalyl acetate and 33.68% linalool in LAV essential oils. One-way analysis of covariance (ANCOVA) indicated a significant difference (p = 0.001) among the groups for high-density lipoprotein cholesterol (HDL-C) when the associated preintervention values were used as a covariate. The related pairwise comparisons revealed that DUB (p = 0.001) and HIR (p = 0.024) had greater HDL-C values than CON. From the two-way ANOVA, an interaction between time (before vs. after) and the groups (DUB vs. HIR vs. LAV vs. CON) was found for HDL-C (p = 0.030). Findings indicated a significant increase in DUB (p = 0.0001) and HIR (p = 0.010) for HDL-C, and there was a significant decrease in DUB (p = 0.023) for low-density lipoprotein cholesterol. However, there was no difference in total cholesterol, triglycerides, and all liver biomarkers.
Increased Functional Connectivity of the Intraparietal Sulcus Underlies the Attenuation of Numerosity Estimations for Self-Generated Words
Authors: Stripeikyte Giedre , Pereira Michael , Rognini Giulio , Potheegadoo Jevita , Blanke Olaf , Faivre Nathan
Published: September 2021

Previous studies have shown that self-generated stimuli in auditory, visual, and somatosensory domains are attenuated, producing decreased behavioral and neural responses compared with the same stimuli that are externally generated. Yet, whether such attenuation also occurs for higher-level cognitive functions beyond sensorimotor processing remains unknown. In this study, we assessed whether cognitive functions such as numerosity estimations are subject to attenuation in 56 healthy participants (32 women). We designed a task allowing the controlled comparison of numerosity estimations for self-generated (active condition) and externally generated (passive condition) words. Our behavioral results showed a larger underestimation of self-generated compared with externally generated words, suggesting that numerosity estimations for self-generated words are attenuated. Moreover, the linear relationship between the reported and actual number of words was stronger for self-generated words, although the ability to track errors about numerosity estimations was similar across conditions. Neuroimaging results revealed that numerosity underestimation involved increased functional connectivity between the right intraparietal sulcus and an extended network (bilateral supplementary motor area, left inferior parietal lobule, and left superior temporal gyrus) when estimating the number of self-generated versus externally generated words. We interpret our results in light of two models of attenuation and discuss their perceptual versus cognitive origins.

SIGNIFICANCE STATEMENTWe perceive sensory events as less intense when they are self-generated compared with when they are externally generated. This phenomenon, called attenuation, enables us to distinguish sensory events from self and external origins. Here, we designed a novel fMRI paradigm to assess whether cognitive processes such as numerosity estimations are also subject to attenuation. When asking participants to estimate the number of words they had generated or passively heard, we found bigger underestimation in the former case, providing behavioral evidence of attenuation. Attenuation was associated with increased functional connectivity of the intraparietal sulcus, a region involved in numerosity processing. Together, our results indicate that the attenuation of self-generated stimuli is not limited to sensory consequences but is also impact cognitive processes such as numerosity estimations.
Tearing, Stitching, Quilting
Authors: Price Yasmina
Published: September 2021

This article analyses the short film and multi-screen installation of America (2019/2020) and the documentary feature Time (2020) by Garrett Bradley as works of radical historiography. The materiality of the gestures of tearing and stitching are a key to understanding Bradley’s methodology as a double gesture of disassembly and reassembly. The use of the lost and recovered fragments of the 1913 Lime Kiln Club Field Day in America and private self-documentation of home movies in Time offer disrupt dominant forms of history. Bradley’s distinctive strategy is a suturing of these archival materials with her own contemporary footage, yielding an aesthetic of fluid black-and-white quilting. Bradley’s abolition poetics function as an urgent contemporary process of recovery that, without ignoring or eliding the traumas of present or past violence, suggests that there can yet be an acknowledgment of the generative potential of the beauty processes of survival that have always been generated alongside them.
“Netflix and Heal”
Authors: Horeck Tanya
Published: September 2021

This article explores how binge-watching shifted from guilty pleasure to essential self-care during the extended lockdown prompted by the COVID-19 pandemic. While binge-watching was prescribed as one of the most effective ways to ward off lockdown ennui, quarantine conditions also led to its reframing as a politically productive activity, one tied to social-justice projects. Following the worldwide outrage over the murder of George Floyd in May 2020, listicles emerged of antiracist films and TV shows for viewers to watch as a means of converting them from unreflective couch potatoes into socially enlightened citizens. While such lists are problematic, COVID culture’s recasting of binge-watching as civic duty compels reflection on how viewing habits in the streaming era might be related to public pedagogy around social-justice struggles. The article concludes by pointing to the continued relevance of binge-watching as a concept that captures the affective intensities of internet TV and user-directed viewing during the pandemic and beyond.
From Spectatorship to “Survivorship” in Five Critical Propositions
Authors: Alexander Neta
Published: September 2021

Often theorized through the negative framework of addiction or passivity, binge-watching has been transformed into a civic duty and a mode of survival during the COVID-19 pandemic. Exploring this recent plot-twist in bingeing scholarship, this article proposes five new ways to study the most dominant spectatorial mode under corona-capitalism. These propositions include studying how the pandemic turned bingeing into an antidote to “languishing,” a feeling of sadness and exhortation that, if unrecognized, might lead to depression; exploring co-watching apps in order to move away from the cliché of bingeing as an individual activity; unpacking the importance of narrative causality during the pandemic’s prolonged structure and temporal limbo; paying close attention to interface design decisions, such as the addition of a “playback speed” feature to Netflix in August 2020; and, finally, demonstrating how binge-watching trains viewers to ignore their basic biological needs while turning them into unpaid laborers.

Published: September 2021

The article is devoted to the role of classical university education in the training of highly qualified, highly competitive teaching staff capable of forming the image of a new school in modern conditions. The achievement of such a complex task is ensured by identifying and implementing the heuristic capabilities of a classical university in the development of pedagogical education. The author associates such opportunities with its fundamentalization, research orientation, advanced character, etc. The purpose of the article is to present the results of a scientific study related to the definition and theoretical justification of possible ways to implement models of teacher education as an optimal “scenario” for training elite teachers in a classical university. Methodology and methods of research. The methodological basis of the research is the philosophical provisions about a person as a subject of his own life activity; the unity and interrelation of processes and phenomena, general and special. The general methodology of the research is represented by a system-synergetic approach that allows us to consider professional and pedagogical training in a classical university as an open developing system in the “school-university-school”continuity relations; a holistic approach as a methodological orientation towards the formation of a holistic personality of a future teacher, as well as the integrity of the system of professional and pedagogical training at a classical university; an individual-personal approach that provides an opportunity to study along an individual educational trajectory. The main research methods were the analysis of scientific literature, theoretical generalization and modeling. The results of the study. As a result of the theoretical and experimental work carried out, it is proved that the quintessence of the heuristic capabilities of the classical university determines the development and implementation of innovative models for the development of pedagogical education. The author gives a description of each model, indicating its features and “contribution” to the training of future teachers in the system of university classical education. In conclusion, it is concluded that the proposed innovative variable models for the development of pedagogical education at a classical university will ensure the success of professional pedagogical training of future teachers, bring it to a fundamentally new level by realizing the valuable potential of a classical university.

Published: September 2021

The inclusion of foreign students in the educational process of Russian higher education makes the problem of intercultural interaction actual. The selection of foreign students as subjects of intercultural interaction introduces a certain specificity in the functioning and construction of the educational space of the university, requires a preliminary study of their personal and educational needs. From the side of foreign students, the article examines Chinese students, since this contingent of students is the bearer of a specific oriental culture; represents a country that prioritizes the development of Russian-Chinese bilateral relations; and dominates in number among foreign students from the Far Abroad. The purpose of the article is to identify specific motivational, value orientations and expectations of Chinese students studying together with Russian students in vocational training programs at a Russian university in order to develop diagnostic tools used to collect data on the subjects involved in the process of interaction within the educational space of the university. Research methodology and methods. The study was carried out from the standpoint of a culturological approach, in which the subjects of pedagogical interaction are considered as representatives of a certain socio-cultural environment. In the conclusion, based on the data obtained, the main guidelines of pedagogical activity for the organization of intercultural interaction between Chinese and Russian students within the educational space of the university are presented.
Are Academics Driven by Managerialism? Governance and the Changing Role of Academics on the Way Towards a Knowledge Society
Authors: Teichler Ulrich
Published: September 2021

Changes in the governance system have been viewed as one of the key issues of higher education since about the 1990s. In many countries, the “managerial university” emerged accompanied by a controversial discourse about its strengths and about dangers implied. As academics are key actors performing key functions in higher education and as governance reforms increased the power of university management to steer academics, the academics’ perception of and response to the “managerial university” is crucial for its successes and failures. International comparative surveys of academics undertaken in the early 1990s and during the years 2007-2010 indicate that the modes of governance and the responses to these modes by academics vary more substantially across countries than the convergent international discourse suggests. Altogether, scholars’ views and behavior seem to have changed to a lesser extent than expected. The third comparative survey of that kind addresses similar issues, but additionally raises the question of whether strong footprints can be observed of the move toward a “knowledge society” with regard to the governance of higher education and academics’ views and activities.
Work Motivation and Career Autonomy as Predictors of Women’s Subjective Career Success in STEM
Authors: Schmitt Miriam , Lauer Sabine , Wilkesmann Uwe
Published: September 2021

The minority status of women in science, technology, engineering and mathematics (STEM) professions makes their successful career development difficult. Due to gender-specific challenges, career dissatisfaction contributes to women dropping out of STEM careers. Therefore, women’s subjective career success (SCS) is important to persist and progress in their STEM careers. This study analyzed the influence of different types of work motivation and the perceived career autonomy on SCS of women. Specifically, 318 women working in STEM professions in Germany completed a quantitative online questionnaire. Using an ordinary least squares regression for variables predicting SCS measured as career satisfaction, we found that an intrinsic work motivation positively affects women’s SCS. The perception of high career autonomy was related positively, and the perception of low career autonomy was related negatively to SCS. Unexpectedly, the findings also revealed the positive influence of income on women’s SCS. The findings show that intrinsic work motivation and high perceived autonomy are promoting factors for SCSs, which could also contribute to their retention in STEM professions.
Management and Governance in Higher Education: South African Universities under Siege
Authors: Wolhuter C.C. , Langa P.
Published: September 2021

The recent spate of changes in university management worldwide should be carefully considered, interrogated and assessed against its impact on the capacity of the university fulfilling its unique role in society. For various justifiable reasons, South African higher education has been finding itself under the spotlight of the international community since 1994. The article surveys the South African academic profession vis à vis the changes that have been taking place regarding university governance and management. It is concluded that the South African academic profession, as far as (de jure and de facto) governance and management are concerned, find themselves sandwiched between two forces: from national and institutional governance on top, and the student corps from the bottom. This threatens the very survival of the university. A new exercise surveying the South African academic profession, as provided for by the Academic Profession in Knowledge Society (APIKS) international survey of the academic profession currently taking place, appears both timous and promising.

Published: September 2021

The exposure of healthcare professionals to (un)ethical situations starts in the educational institution, and the first serious cases occur during internships. The aim of the current study is to investigate the problems and causes (concerning unethical situations) related to students’ perception of ethics in the study and practice environment and to describe the awareness of Tallinn Health Care College’s students of professional ethics and the use of existing support systems in solving unethical problems.The findings indicated the importance of ethical communication and behaviour by all respondents. Empathy, ethical feedback, and confidentiality were perceived to be an integral part of ethical standards within the study and training environment. Respondents pointed out that ethical issues may occur not only between a health care professional and a patient, but also between a health care professional and doctor, supervisor, or teacher. A practical approach to ethical decision-making integrated into professional training has been assessed by all respondents.
Trouble with the biography of the sovereign: historiography, archives and national memory
Authors: Fadieiev Volodymyr
Published: September 2021

The proposed article is an exploration of realistic social ontology, devoted to the study of the interaction between national memory, historiography and archives as defining social institutions of the modern era. The study focuses on the problems of formation and transformation of perceptions of the past of the national community — the bearer of sovereignty. During the analysis, the author concludes that national memory, archives and historiography are endowed with their own dynamics, and the relationship between them is a changing constellation of relations, that has undergone a complex evolution over the last two centuries. Beginning in the 19th century, the nature of relations changed in the direction of emancipation of archives from the guidelines of official historiography, distancing historiography from the exercise of state power, and the emergence of a new memorial culture in the late twentieth century. The result of these changes was the emergence of affirmative historiography, which has a significant impact on public life. The author concludes that the urgent problem of today is to create conditions for conflict-free interaction of all participants in the politics of memory in order to avoid politicization caused by inconsistencies in the interpretation of past events.

We report the results of first-principles total-energy calculations for structural properties of scandium nitride (ScN) semiconductor compound in NaCl-type (B1), CsCl-type (B2), zincblende-type (B3), wurtzite-type (B4), NiAs-type (B81), CaSi-type (Bc), B-Sn-type (A5), and CuAu-type (L10) structures. Calculations have been performed with the use of the all-electron full-potential linearized augmented plane wave FP-LAPW method based on density-functional theory (DFT) in the generalized gradient approximation (GGA) for the exchange correlation energy functional. We predict a new phase transition from the most stable cubic NaCl-type structure (B1) to the B-Sn-type one (A5) at 286.82 GPa with a direct band-gap energy of about 1.975 eV. Our calculations show that ScN transforms from the orthorhombic CaSi-type structure (Bc) to A5 at 315 GPa. In agreement with earlier ab initio works, we find that B1 phase transforms to Bc, L10, and B2 structures at 256.27 GPa, 302.08 GPa, and 325.97 GPa, respectively. The electronic structure of A5 phase shows that ScN exhibits a direct band-gap at X point, with Eg of about 1.975 eV.

Authors: Rochimah Nur , Handini Myrnawati Crie , Hapidin Hapidin
Published: September 2021

Many factors can affect children's school readiness, one of which is the family as their closest environment. This research aimed to analyze the effect of family socioeconomic status, family stress, and parental involvement on children's school readiness. This research involves 113 parents and students of group B Kindergarten in the Integrated Waste Processing Site (TPST) in Bantargebang District, Bekasi City, West Java Province. This sample was obtained using the multistage random sampling technique. This study uses path analysis techniques. This study indicates that socioeconomic status, family stress, and parental involvement do not directly affect Children’s school readiness. However, family socioeconomic status has a negative direct effect on family stress, and family stress can also have a negative direct effect on parental involvement in children's education. These findings imply that it is important to create a warm and supportive family environment to optimally carry out their roles and functions in children's education.
Pubertal Suppression, Bone Mass, and Body Composition in Youth With Gender Dysphoria
Authors: Navabi Behdad , Tang Ken , Khatchadourian Karine , Lawson Margaret L.
Published: September 2021

BACKGROUND AND OBJECTIVES

Puberty onset and development contribute substantially to adolescents’ bone mass and body composition. Our objective with this study was to examine the effects of gonadotropin-releasing hormone agonists (GnRHa) on these puberty-induced changes among youth with gender dysphoria (GD).

METHODS

Medical records of the endocrine diversity clinic in an academic children’s hospital were reviewed for youth with GD seen from January 2006 to April 2017 with at least 1 baseline dual-energy radiograph absorptiometry measurement.

RESULTS

At baseline, transgender females had lower lumbar spine (LS) and left total hip (LTH) areal bone mineral density (aBMD) and LS bone mineral apparent density (BMAD) z scores. Only 44.7% of transgender youth were vitamin D sufficient. Baseline vitamin D status was associated with LS, LTH aBMD, and LS BMAD z scores. Post-GnRHa assessments revealed a significant drop in LS and LTH aBMD z scores (transgender males and transgender females) without fractures and LS BMAD (transgender males), an increase in gynoid (fat percentage), and android (fat percentage) (transgender males and transgender females), and no changes in BMI z score.

CONCLUSIONS

GnRHa monotherapy negatively affected bone mineral density of youth with GD without evidence of fractures or changes in BMI z score. Transgender youth body fat redistribution (android versus gynoid) were in keeping with their affirmed gender. The majority of transgender youth had vitamin D insufficiency or deficiency with baseline status associated with bone mineral density. Vitamin D supplementation should be considered for all youth with GD.

Authors: Solera-Martínez Monserrat , Herraiz-Adillo Ángel , Manzanares-Domínguez Ismael , De La Cruz Lidia Lucas , Martínez-Vizcaíno Vicente , Pozuelo-Carrascosa Diana P.
Published: September 2021

CONTEXT

High-intensity interval training (HIIT) has been widely used to prevent and treat cardiovascular risk factors in adolescents and adults; nevertheless, the available evidence in children is scarce.

OBJECTIVE

To synthesize evidence regarding the effectiveness of HIIT interventions on improving cardiovascular risk factors and cardiorespiratory fitness (CRF) in children from 5 to 12 years old.

DATA SOURCES

We searched 5 databases, Medline, Embase, SPORTDiscus, the Cochrane Library, and Web of Science.

STUDY SELECTION

Randomized controlled trials (RCTs) evaluating the effectiveness of HIIT interventions on cardiometabolic risk factors and CRF in children were included.

DATA EXTRACTION

Meta-analyses were conducted to determine the effect of HIIT on body composition, cardiometabolic and CRF variables in comparison with nontraining control groups.

RESULTS

A total of 11 RCTs and 512 participants were included. The results of the meta-analysis revealed a significant improvement in peak oxygen uptake (standardized mean difference [SMD] = 0.70, 95% confidence interval [CI] = 0.28 to 1.12; P = 0.001], in total cholesterol [SMD = −1.09, 95% CI = −1.88 to −0.30; P = 0.007], in low-density lipoprotein cholesterol [SMD = −1.28, 95% CI = −2.34 to −0.23; P = 0.017] and triglycerides [SMD = −0.71, 95% CI = −1.15 to −0.28; P = 0.001) levels.

LIMITATIONS

Because of the small number of available RCTs, it was not possible to conduct a subgroup analysis or a linear meta-regression analysis.

CONCLUSIONS

HIIT is a feasible and time-efficient approach for improving CRF, total cholesterol, low-density lipoprotein cholesterol, and triglycerides levels in children.

During a study on fungal endophyte diversity, Nigrospora lacticolonia Mei Wang & L. Cai was isolated from healthy leaves of Guarea macrophylla, a shade tree in the Cocoa agroecosystem (cabruca) in Brazil. We confirmed the identity of the specimens using morphological data and a phylogenetic reconstruction based on molecular markers (internal transcribed spacer region (ITS), β-tubulin (TUB2), and translation elongation factor 1-α (TEF) sequences). The specimen presented black globose or slightly ellipsoidal conidia, and the conidiophores were reduced to conidiogenous cells. This is the first report of N. lacticolonia in the Neotropical Region.
Evolution of State Policy Towards Labour Desertion in 1944-1945
Authors: Yury Belonogov
Published: September 2021

The object of scientific research was the evolution of legislation and its law enforcement practice with respect to the deserters from military industrial enterprises at the final stage of World War II. This evolution formally suggested an obvious change of emphasis in the penal policy of labour mobility control: from toughening law enforcement practices to realization of large-scale amnesties of workers who arbitrarily left their places of work.On the basis of the local archival materials the author analyzes practical implementation of innovations reflected in the Decree of the Government of the USSR of June 29, 1944 (change in the procedure for searching and punishing deserters; bringing economic leaders to criminal and party responsibility for non-compliance with the norms of the Decree of December 26, 1941; preventive measures aimed at improvement of working and living conditions). However, attempts of systemic improvement of existing legislation and its enforcement practices faced with certain institutional constraints existed due to the nomenclature organization of power and the supply and demand correlation in the labour market. The author sees the reasons for the amnesties in 1944‒1945 in the low efficiency of toughening punitive measures, excessively high administrative expenses in the process of the Decree of December 26, 1941 realization. It is mentioned that holding the amnesty did not change the substance of the legislation on criminal prosecution for unauthorized abandonment of the workplace of workbut was only the reaction of the state which defended the departmentinterests of the military industry people's commissariats concerning the provision of enterprises with labor force, the reaction to the poorly effective search for labor deserters.
Work of Foreign Powers of War During the Restoration of the Central Chernozemye Industry in the Years the Great Patriotic War

The study of aspect prisoners of war in the restoration of the USSR industry during the Great Patriotic War arouses scientific interest of native historiography. Contradictory opinions and assessment of foreign prisoners of war contribution to the restoration of the USSR industrial facilities accentuate the relevance of the topic. The study of this issue at the regional level arouses great interest. The practical significance of the topic lies in the fact that, firstly, it is the material for further study of the problem of foreign prisoners of war on the territory of the Central Chernozemye Region, and secondly, it can be used as the material for the examination of a number of topics on the history of prisoners of war during the Great Patriotic War at government level. During the Great Patriotic War the front line passed through the territory of the Central Chernozemye Region (summer 1942 – winter 1943). Kursk and a part of Voronezh region were occupied by Nazi troops. In the second half of 1942 the first production camps for foreign prisoners of war were established in the Central Chernozemye Region. The increase in the number of camps, the number of prisoners of war and their involvement in production began in 1943. The main reason for the use of prisoners of war labor was, first of all, associated with a sharp increase in the number of prisoners of war after the Battle of Stalingrad; and secondly, with a shortage of manpower. In the first months of the camps operation the involvement of prisoners of war in the work remained low. But in the second half of 1944 it began the massive use of prisoners of war labor. Their labor included restoration work in all industries of the Central Chernozemye Region. By the end of the war prisoners of war had been recruited to work according to their civil specialties. Despite the active use of prisoners of war labor as a part of the complex of restoration measures in the Central Chernozemye Region their contribution was insignificant in comparison with the material damage caused. The article, based on the analysis of archival materials and historical literature, as well as on the historical-comparative, systemic, statistical and other methods of scientific research, shows the contribution of foreign prisoners of war to the restoration of industrial facilities in the Central Chernozyom region during the Great Patriotic War.

Resumo Introdução A avaliação de programas pode nortear a tomada de decisão de gestores. Objetivo Analisar o Índice de Implementação (II) da Rede Mãe Paranaense (RMP). Método Pesquisa quantitativa retrospectiva realizada em três Regionais de Saúde (RS) do Paraná, Brasil, totalizando 55 municípios. Construíram-se indicadores de avaliação antes (2010-2011) e depois (2012-2013) da implementação da Rede. Estabeleceram-se cinco domínios com variáveis coletadas no Sisprenatal, Sinasc, SI-PNI, SIM e informações nas RS. Para cada domínio, avaliou-se a influência das variáveis do II (adequado e inadequado). Utilizou-se do programa XLStat2014® e aplicaram-se os testes de Shapiro-Wilk, regressão logística, análise da variância fatorial e Monte Carlo, com nível de significância p < 0,05. Resultados O II antes (2010-2011) e depois (2012-2013) da RMP, nas três RS, apresentou diferença estatística significativa (F6,156 = 129,14; p = 0,000). Em 2010, todas as RS foram estatisticamente semelhantes (p > 0,05), demonstrando equivalência nos municípios; em 2010-2011, o II da 10ª RS foi maior que da 9ª RS; em 2011-2012, os valores da 10ª e da 17ª RS foram estatisticamente superiores aos da 9ª RS (p < 0,05); em 2012-2013, a 10ª RS apresentou elevado crescimento, semelhante ao da 17ª RS (p > 0,05) e superior ao da 9ª RS (p < 0,05). Conclusão O II para avaliar o desempenho da Rede nas três RS se mostrou adequado à avaliação dos indicadores.

Objective: to assess the prevalence of pharmacological adherence in patients with coronary artery disease and to identify factors associated with adherence. Method: a crosssectional, correlational study, including 198 patients with a previous diagnosis of coronary artery disease. Pharmacological adherence was assessed by the four-item Morisky Green test, and the factors that potentially interfere with adherence were considered independent variables. The association between the variables was determined by the Cox model, with a 5% significance level. Results: 43% of the patients adhered to the treatment. Fatigue and palpitation, never having consumed alcohol and being served by medical insurance were associated with adherence. Lack of adherence was associated with considering the treatment complex, consumption of alcohol and being served by the public health care system. In the multiple analysis, the patients with fatigue and palpitations had a prevalence of adherence around three times higher and alcohol consumption was associated with a 2.88 times greater chance of non-adherence. Conclusion: more than half of the patients were classified as non-adherent. Interventions can be directed to some factors associated with lack of adherence.

ABSTRACT Nitrogen fertilization is essential for wheat yield and quality but needs more accuracy, and the use of proximal optical sensors in the field can assist in this goal. This study aimed to verify if it is possible to use the normalized difference vegetation index (NDVI) obtained throughout the wheat growth phase to estimate the grain yield and the technological quality of the flour from cultivars submitted to nitrogen doses. The experiment was conducted at field conditions in Ponta Grossa, PR, Southern Brazil. The experimental design was randomized blocks in a 4 × 6 factorial scheme with four replicates. The cultivars Quartzo, Gralha Azul, Sinuelo, and Toruk, combined with six doses of N (0, 40, 80, 120, 160, and 200 kg ha-1 of N), were evaluated. The NDVI values were sensitive to both nitrogen doses and the different cultivars. There was a relationship between NDVI and grain yield, protein, and gluten concentration of flour. The NDVI estimated the gluten strength, stability, tenacity, extensibility of the mass, and tenacity/extensibility ratio of the flour obtained at the beginning of the cycle, but not for all cultivars. The determinations of NDVI with active optical sensor GreenSeeker in wheat are efficient to estimate the grain yield and the flour quality under field conditions, allowing to generate models for estimation of these variables separately for each cultivar.

ABSTRACT This study aimed to carry out an economical and productive analysis of carrot production using different irrigation depths and doses of fertilizer. A randomized block design was used arranged in a 6 × 4 factorial scheme, with three replicates. The treatments were constituted by six irrigation depths: (L1: 210.5, L2: 315.7, L3: 421.0, L4: 526.2, L5: 631.5, and L6: 736.7 mm) and four doses of fertilizer: (F1: 226.9, F2: 340.3, F3: 453.8 and F4: 567.2 kg ha-1) applied via fertigation. At the end of the cycle, four carrot roots were collected per plot to estimate yield. The maximum estimated yield of the carrot was 95.4 t ha-1, obtained using 478.1 mm of water and 538.8 kg ha-1 of fertilizer. The best economic return was achieved with 482.0 mm of water and 460.0 kg ha-1 of fertilizer, giving 95.0 t ha-1. The combination of irrigation and fertilizer allows lesser amount of both to be used, giving greater response than when applied separately.
