Authors: Woromogo Sylvain Honore , Ambounda Ledaga Nathalie , Yagata-Moussa Felicite Emma , Mihindou Astride Smeige
Published: July 2021

The objectives of this study were to identify the associated factors with cancerous and precancerous lesions of cervix. In Africa, the incidence of uterine cervical neoplasms varies from one region to another, where most women with uterine cervical neoplasms are seen at an advanced stage. For this reason, uterine cervical neoplasms mass screening reduces the incidence and mortality due to this disease, similar to what is being done in Europe. A cross-sectional analytical study was conducted. Socio-demographic characteristics, gynaecological-obstetrical history, risk factors, data from visual inspection with acetic acid and visual inspection with Lugol, colposcopy impressions and results of cytological analysis were performed. A simple and multiple regression were performed to establish a statistically significant difference between certain factors and the presence of precancerous or cancerous lesions of uterine cervical. In this study, of 63 women diagnosed histologically, 43 had precancerous lesions and 20 had cancerous lesions. we found that being older than 35, having the first intercourse before 18, having an antecedent of STI, being a widow and using of tobacco were risk factors associated with precancerous lesions (p = 0.013 with OR = 3.44 (1.22–9.73), p = 0.009 with OR = 4.07 (1.69–13.08), p < 0.001 with OR = 3.80 (1.94–7.47), p < 0.001 with OR = 9.77 (3.87–24.70) and p < 0.001 with OR = 5.47 (2.60–11.52)) respectively. Only being older than 45, being a widow and using tobacco were risk factors associated with cancerous lesions (p = 0.021 with OR = 2.01 (1.58–3.56), p = 0.02 with OR = 2.96 (2.10–3.87), p = 0.041 with OR = 1.98 (1.46–2.44)) respectively. Among participants diagnosed with uterine cervical neoplasms, there was a significant association with the STI, marital status and smoking. Despite the integration of the detection of precancerous uterine cervical neoplasms lesions into health facilities in Gabon, uterine cervical neoplasms ranks second among women’s cancers in terms of incidence and first in terms of mortality.
A key antisense sRNA modulates the oxidative stress response and virulence in Xanthomonas oryzae pv. oryzicola

Published: July 2021

Pathogens integrate multiple environmental signals to navigate the host and control the expression of virulence genes. In this process, small regulatory noncoding RNAs (sRNAs) may function in gene expression as post-transcriptional regulators. In this study, the sRNA Xonc3711 functioned in the response of the rice pathogen, Xanthomonas oryzae pv. oryzicola (Xoc), to oxidative stress. Xonc3711 repressed production of the DNA-binding protein Xoc_3982 by binding to the xoc_3982 mRNA within the coding region. Mutational analysis showed that regulation required an antisense interaction between Xonc3711 and xoc_3982 mRNA, and RNase E was needed for degradation of the xoc_3982 transcript. Deletion of Xonc3711 resulted in a lower tolerance to oxidative stress due to the repression of flagella-associated genes and reduced biofilm formation. Furthermore, ChIP-seq and electrophoretic mobility shift assays showed that Xoc_3982 repressed the transcription of effector xopC2, which contributes to virulence in Xoc BLS256. This study describes how sRNA Xonc3711 modulates multiple traits in Xoc via signals perceived from the external environment.

Published: July 2021

The intestinal microbiota has been associated with the occurrence and development of mastitis, which is one of the most serious diseases of lactating women and female animals, but the underlying mechanism has not yet been elucidated. Aryl hydrocarbon receptor (AhR) activation by microbiota tryptophan metabolism-derived ligands is involved in maintaining host homeostasis and resisting diseases. We investigated whether AhR activation by microbiota-metabolic ligands could influence mastitis development in mice. In this study, we found that AhR activation using Ficz ameliorated mastitis symptoms, which were related to limiting NF-κB activation and enhancing barrier function. Impaired AhR activation by disturbing the intestinal microbiota initiated mastitis, and processed Escherichia coli (E. coli)-induced mastitis in mice. Supplementation with dietary tryptophan attenuated the mastitis, but attenuation was inhibited by the intestinal microbiota abrogation, while administering tryptophan metabolites including IAld and indole but not IPA, rescued the tryptophan effects in dysbiotic mice. Supplementation with a Lactobacillus reuteri (L. reuteri) strain with the capacity to produce AhR ligands also improved E. coli-induced mastitis in an AhR-dependent manner. These findings provide evidence for novel therapeutic strategies for treating mastitis, and support the role of metabolites derived from the intestinal microbiota in improving distal disease.

Authors: Shulgina Christina
Published: July 2021

The article deals with a classification of sources of information about the verbal situation of an insult, which is subject to research during the production of a forensic linguistic examination. The objective side of the crimes established by Articles 319 and 297 of the Criminal Code of the Russian Federation is verbal aggression, expressed in insulting a representative of the authorities, participants in the trial, and persons involved in the administration of justice. The author examines various ways of fixing the speech situation of an insult and information about it and also puts forward a hypothesis about the possibility of carrying out a linguistic study of a conflict speech event recorded in the testimony of participants in criminal proceedings while observing a certain order of registration of a procedural document
Representation of a Film Recipient in Neologisms of the English Cinematic Discourse
Authors: Biryukova Polina
Published: July 2021

This work analyzes English neologisms of cinematic discourse that characterize a film recipient – they name the viewers, describe the process of their perception of TV content, denote acceptance or rejection of its content, the incentive nature of cinema. Based on the semantic components contained in the definitions and/or the contextual field of the neologisms at hand, a conclusion was drawn on the ever-growing role of cinematography in a personal life of a 21st century person, its ubiquity in daily life both in the form of a moving image and in other incarnations. The neologisms under consideration indicate that viewers analyze TV content, discuss it, engage in productive activity while watching a movie, visit filming locations, and see images of famous characters in their natural habitat. A certain range of neologisms in English cinematic discourse speaks of the tendency of a significant number of modern film recipients to popularize negative characters, to justify their immoral acts. However, this work also emphasizes that this is not the first time this trend is taking place.
Some Peculiarities of Reduplication as a Musical Device of James Joyce in «Finnegans Wake» and its Translatability
Authors: Naugolnykh Evgeniya
Published: July 2021

The article deals with language experiments of James Joyce in his novel «Finnegans Wake». The reduplication in the novel is found to be multifaceted and multifunctional. Not only does it strengthen an emotional component, but also creates tone-painting, thus being an inherent part of the author’s word play. A detailed classification of the randomly selected occasional lexical units formed by reduplication is suggested. Among the partial reduplication, divergent modifications are found to dominate. The research concerned the possibilities of translating the revealed occasional words into Russian (A. Rene, A. Volokhonskii versions), German (D. Stündel version) and Spanish (M. Zabaloi). Various translation strategies are considered. The research has found that interlingual transference of the writer’s reduplication is possible, but highly subjective and therefore radical transformation of the source text is often required, leading to creation of the modified version of «Finnegans Wake» rather than its translation in the true sense.
Vendégtér-paradoxon : Budapesti luxusszállodák miliője a helyi társadalom szemszögéből
Authors:   , Juhász-Dóra Katalin
Published: July 2021

Az értekezés célja az elméleti keretet biztosító szakirodalom alapján a luxusszállodai környezet és szolgáltatások helyi társadalom által történő feltáró elemzése, az elsődleges céllal turisztikai szolgáltatást nyújtó városi szállodák, mint turisztikai terek vizsgálata a helyi lakosok szemszögéből két luxusszálloda mintáján keresztül. A kutatás során ismertettük, de a tartalmi és terjedelmi vonatkozások miatt nem tértünk ki részletesen a design és az építészet, továbbá a szállodák üzemeltetési és tulajdonlási formáival kapcsolatos aspektusokra, ugyanis ezek a környezeti térészlelés és a miliő elmélete kapcsán nem voltak annyira relevánsak, mint a fogyasztói viselkedés. Az egyik fő megállapításunk az, hogy a szállodák belső környezete számos kiaknázatlan lehetőséget rejt, menedzseri javaslat, hogy a jövőben javasolt – a luxusszálloda adottságai, elhelyezkedése, üzemeltetési formájának figyelembevételével – a kiegészítő szolgáltatások révén a helyi közönséget is megcélozni, ugyanis visszatérő vendégeket eredményezhet az ilyen szempontú megközelítés. A szakirodalom és a két esettanulmány kutatási eredményei alapján a szállodai környezet azon elemeit azonosítottuk, amelyek a vendég visszatérése szempontjából hozzájárulnak, ugyanis a helyi lakosok viselkedésének szempontjából ez a kérdés volt szignifikáns menedzseri nézőpontból: - helyspecifikus elemeket (megközelíthetőség, lokáció, épület mérete, alaprajz, lobbi, étterem, bár, rendezvényterület, kulturális örökség, és panoráma) - időspecifikus elemeket (történelmi múlt, látogatás gyakorisága, látogatás időtartama) - turisztikai miliő elemeit (épített környezet, szálloda belső design, vendégkör, személyzet, egyes egységek hangulata, fények, színek, hőérzet, anyagok, illatok/szagok, zene, zörej, hangok). A két esettanulmány két történelmi jelentőséggel bíró luxusszállodában készült, a visszatérés elemeiként az alábbi tényezőket azonosítottuk: vendégéjszaka eltöltése, egyéb szolgáltatás igénybevétele, rendezvényeken/programokon való részvétel, műemlék vagy kiállítás megtekintése. A szállodai környezet vizsgálata mellett azokat a szállodai szolgáltatásokat azonosítottuk, amelyek a helyi lakosok számára kínálhatóak.

Railway superstructure for high-speed rails
Authors: Týfa Lukáš , Kruntorád Jan , Tomaschko Ondřej
Published: July 2021

The construction of the track is solved as a conventional (with track ballast) or as a ballastless track (without track ballast). When deciding on the choice of the most suitable track design for high-speed rail, it is necessary to emphasize that with increasing line speed, the requirements for the quality of the track geometry increase, including the size of the deviations of individual geometric parameters of the track from the projected values. When assessing the choice of track structure – especially for high-speed rails – it is therefore necessary and correct to assess the total costs (investment and operational) for a sufficiently long time. DB Netz AG’s present experience with a ballastless track since its first implementation in 1972 in Rheda station, for almost 50 years, shows that the required lifetime of 60 years has its real justification. In addition, current research and development in the field of ballastless track is moving towards extending the life of ballastless track well beyond this limit. The paper is focused on the comparison a ballasted and ballastless track construction. It deals in more detail with evaluation of the advantages and disadvantages of a ballastless track construction. The main objective is to assess the use of ballastless track structure for the construction of high-speed lines.

Gonadotropin-dependent precocious puberty (central) is a condition resulting from the early (up to 8 years in girls and 9 years in boys) reactivation of the hypothalamic-pituitary-gonadal axis. An increase in the secretion of sex steroids by the gonads in this form is a consequence of the stimulation of the sex glands by gonadotropic hormones of the pituitary gland. In the absence of central nervous system abnormalities, CPP is classified as idiopathic and as familial in some cases, emphasizing the genetic origin of this disorder. Loss-of-function mutations in Makorin Ring Finger Protein 3 (MKRN3) are the most common identified genetic cause of central precocious puberty compared to sporadic cases. In the present study we performed the first descrition of 3 family cases of central precocious puberty duo to novel MKRN3 gene mutation detected by NGS in the Russian Federation.

Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder characterised by lack of pubertal development and infertility, due to deficient production, secretion or action of gonadotropin-releasing hormone (GnRH). Clinically, there are variants of CHH with hypo-/anosmia (Kalman syndrome) and normosmic hypogonadotropic hypogonadism. Given a  growing list of gene mutations accounting for CHH, the application of next generation sequencing (NGS) comprises an excellent molecular diagnostic approach because it enables the simultaneous evaluation of many genes. Biallelic mutations in GNRHR gene lead to the development of hypogonadotropic hypogonadism with normosmia. In this paper, we describe 16 patients with proven GnRH resistance and estimate the frequency of pathogenic variants in the GNRHR gene in the Russian population.

Authors: Corral-Martínez Marta , Gómez-Cuevas Ana María
Published: July 2021

Uno de los problemas frecuentes que afrontan los docentes en las aulas son las conductas disruptivas. Estudios previos han mostrado que variables afectivas como la empatía y la inteligencia emocional se relacionan con menos conductas problemáticas. El presente trabajo es un estudio piloto en el que se evaluó la frecuencia de las conductas disruptivas (altas y bajas) en un grupo de alumnos de educación primaria (N=25), así como su relación con la inteligencia emocional y la empatía. Para ello se utilizaron el Cuestionario de Conductas disruptivas en el aula de Simón, Gómez y Alonso-Tapia (2013), la versión española del inventario de empatía IRI (Davis, 1983), y la versión española del EQ-YV de Bar-on (1997). Los resultados muestran una relación negativa entre distintas dimensiones de la inteligencia emocional y la empatía con la frecuencia de conductas disruptivas. También se observó un mayor nivel de inteligencia emocional y empatía en el alumnado con menor frecuencia de conductas disruptivas leves y graves. No se han observado diferencias entre los niños y las niñas.
Real-Time Fuel Consumption Monitoring System Integrated With Internet Of Things (IOT)
Authors: Hapsari Adella Winanda , Prastowo Hari , Pitana Trika
Published: July 2021

Fuel is an important aspect in the operation of ships that require high costs. The high cost of fuel is not followed by an automatic fuel monitoring process. By not using the fuel consumption monitoring method that works automatically, the shipping management does not know for sure the ship's fuel consumption is in accordance with the shipping mileage, thus triggering fraud committed by the ship's crew against the ship's fuel. Fuel consumption monitoring is carried out primarily to identify opportunities to improve energy efficiency and reduce costs. By following technological developments, Internet of Things (IoT) technology has begun to be applied in various industrial fields because it can transmit data in real-time via the internet network without human-to-human or human-to-computer interaction. In this research, the design of models and experiments related to a monitoring system for fuel consumption was carried out using sensors and microcontrollers integrated with the internet to obtain accurate and real-time data. The test results show that the volume of fuel available in the tank, the volume of fuel discharged, the flow rate of fuel, and the location of the system can be known by the user in real-time via the IoT website. Based on the results of measurements using an ultrasonic level sensor, it is known that the measurement results are quite accurate with a deviation of ± 0.5 cm. Meanwhile, the measurement results by the flow sensor are less accurate because the fuel flow only relies on the force of gravity.

A ciclagem de nutrientes é um processo chave na manutenção de florestas tropicais. A importância da serapilheira na ciclagem de nutrientes é um tema relevante e vem se tornando a base de diversos estudos nas últimas décadas. Com o objetivo de realizar uma análise quali-quantitativa sobre os estudos de serapilheira no Brasil, foi realizada uma bibliometria da produção científica no período de 2008-2019. Analisamos 119 artigos, distribuídos em 19 periódicos. O ano de 2015 apresentou o maior número de publicação com 18 artigos. O estado do Rio de Janeiro representou 13,45% da produção cientifica, e o bioma Mata Atlântica concentrou 55,72% das publicações, o que pode estar relacionado à presença das Fundações de Apoio à Pesquisa que mais investem na ciência brasileira. Mais da metade das publicações realizaram pesquisas em apenas um ecossistema. Do total de publicações, 71,4% quantificou o aporte da serapilheira, enquanto 21,9% o estoque. Os maiores valores de massa seca de serapilheira foram registrados no bioma Amazônia, com 8,32 ± 2,57 Mg ha-¹ ano-1 e nos ecossistemas caracterizados como floresta primária, com 8,19 ± 3,27 Mg ha-¹      ano-¹. Para o estoque, os estudos realizados no Cerrado apresentaram as maiores médias, com 7,24 ± 1,98   Mg ha-¹. Os resultados demonstraram que o número de publicações se concentra em determinadas regiões brasileiras. Além disso, percebem os que o maior número de estudos em ecossistemas de plantio monoespecífico e misto pode estar relacionado à importância ecológica e econômica para o Brasil.

Published: July 2021

Rice is the main staple food after wheat for more than half of the world’s population in Asia. Apart from carbohydrate source, rice is gaining significant interest in terms of functional foods owing to the presence of aromatic compounds that impart health benefits by lowering glycemic index and rich availability of dietary fibers. The demand for aromatic rice especially basmati rice is expanding in local and global markets as aroma is considered as the best quality and desirable trait among consumers. There are more than 500 volatile aromatic compounds (VACs) vouched for excellent aroma and flavor in cooked aromatic rice due to the presence of aromatic hydrocarbons, aldehydes, phenols, alcohols, ketones, and esters. The predominant VAC contributing to aroma is 2 acetyl-1-pyrroline, which is commonly found in aerial parts of the crop and deposits during seed maturation. So far, literature has been focused on reporting about aromatic compounds in rice but its extraction, characterization, and quantification using analytical techniques are limited. Hence, in the present review, extraction, characterization, and application of aromatic compound have been elucidated. These VACs can give a new way to food processing and beverage industry as bioflavor and bioaroma compounds that enhance value addition of beverages, food, and fermented products such as gluten-free rice breads. Furthermore, owing to their nutritional values these VACs can be used in biofortification that ultimately addresses the food nutrition security.

Numerical examples are carried out for vibration characteristic of SW-BNNT with an extra attached mass. Our results show that the vibration frequencies and magnitudes of SW-BNNT are very sensitive to the extra attached mass. In addition, the influence of length and chirality of SW-BNNT on the vibration frequencies and magnitudes of SW-BNNT with an extra attached mass are also examined in detail. This investigation indicates that SW-BNNTs have a great potential in the field of sensor technology.
Dual Topical Antibiotic Application Prior to Sternotomy Closure Reduces Sternal Wound Infection Rates: A Simple Solution to a Grave Morbidity
Authors: Ali Ihab , Mourad Faisal
Published: July 2021

Background: A significant cohort of patients who undergo cardiac surgery suffer from diabetes and atherosclerosis. These patients have impaired tissue perfusion, hence a reduction in antibiotic concentration in the subcutaneous tissues at the side of the mammary artery harvesting. Topical application of gentamicin and vancomycin before wound closure broadens the antibiotic spectrum and reduces the incidence of deep sternal wound infection. In this article, we compare the use of single versus dual application of vancomycin and/or gentamicin in sternotomy wounds in a single tertiary center.
Methods: An observational cohort analysis with three sequential patient groups (N = 2550) was performed at Ain Shams University Hospital in Cairo. A control group (N = 850), vancomycin only group (N = 850), and vancomycin plus gentamicin group (N = 850) were included in the study, during the three-year period from January 2017 to December 2019. Patients who had minimal access surgery were excluded from this study. The presence of an infected postoperative sternotomy wound was assessed in all patients.
Results: The presence of an infected sternotomy wound (El Oakley class 2B) was present in 38 patients (4.5%) in the control group, in 19 patients (2.2%) in the vancomycin group, and in nine patients (1.1%) in the dual antibiotic group, respectively (P < .001). In contrast to the usual, we had a proliferous growth of gram-negative organisms 29 (3.4%) in the control group, 10 (1.2%) in the vancomycin group, and five (0.6%) in the dual antibiotic group, respectively (P < .001).
Conclusion: Deep sternal wound infection is a major cause of post-cardiac surgery morbidity and prolonged hospital stay. Adding the simple step of topical application of vancomycin and gentamicin to the sternotomy wound at the end of the procedure appeared to significantly reduce deep wound infection rates.

WORLDSKILLS RESPONSE TO TRANSVERSAL SKILLS
Authors: Shackleton Jenny , Messenger Sally
Published: July 2021

Developing and maintaining the skills of an increasingly global workforce is a challenge all governments face, particularly as the world emerges from the effects of the2020/21 pandemic. Coupled with the impact of the “Fourth Industrial Revolution” working lives are changing at an unprecedented rate. This article looks at the critical role of transversal skills in enabling ‘employability’, as traditional occupations reconfigure, shift and new roles rapidly appear. Whilst definitions and classifications vary it is agreed that transversal skills are those which an individual can apply across all work roles and life situations, - they are a platform for flexibility, adaptability, and progression.
For over 70 years WorldSkills International (WSI) has been working with governments to raise the profile of technical and vocational education (TVET), principally through a biennial global skills competition focusing on excellence. In recent years WSI has been investing in a strong research base working with global partners such as the OECD, ILO and UNESCO. In 2012 it began a project to develop WorldSkills Occupational Standards (WSOS).  This article plots the journey WSI has taken to strengthen and embed transversal skills within its standards to ensure the currency of the Competition and more widely drive global skills development forward.

Published: July 2021

The objectives of this study were to evaluate the current dust extraction efficiency used in the Malaysian furniture industry and also the effectiveness of using engineered nanoparticle (ENP)-added coatings to reduce dust emission in the wood finishing operation. This study was in response to the enforcement of the Clean Air Regulation (2014), which requires significant improvements in the air quality and the work environment in the wood-based industry in Malaysia. A series of sanding experiments with different abrasive grit sizes and different coating types were conducted to determine the dust emission levels. The results suggested that higher capture velocity of 30 m/s was necessary to effectively capture the wood coating dust emitted. Further, ENP-added wood coatings did not differ markedly from conventional coatings with regard to dust emission characteristics. The study also revealed that total dust concentration had an inverse relationship, while the amount of finer dust particles was linearly related to the coating film hardness. Therefore, to comply with the Clean Air Regulation, the Malaysian furniture industry needs to significantly improve its dust extraction system.

Dolphin morbillivirus (DMV) is a pathogen of great concern in free-ranging cetaceans. Confirmation and staging of morbillivirus infections rely on histology and immunohistochemistry (IHC), following molecular detection. As at the present time no specific antibodies (Abs) against DMV are available, two heterologous Abs have been used worldwide for the examinations of morbillivirus infections of cetaceans. One is a monoclonal Ab (MoAb) prepared against the N protein of canine distemper virus (CDV), whereas the other is a polyclonal Ab raised in rabbits against rinderpest virus (RPV). Both Abs are known to show cross-reactivity with DMV. In this study we compared the labelling quality and the neuroanatomical distribution of staining with these two Abs by means of IHC analysis. To this end, serial sections of the target organs from ten free-ranging stranded cetaceans, previously diagnosed as being infected with DMV by PCR and/or serology, were subjected to IHC. The brain, lungs and lymph nodes of one animal were found to be positive with both Abs. From two other animals, the brain and the spleen, respectively, tested positive only with the polyclonal Ab. In the positive brain tissues, multifocal immunostaining was observed, with similar staining location and extent, with the two antibodies tested. Our results suggest that the polyclonal anti-RPV Ab might have a stronger binding activity to DMV than the anti-CDV MoAb. Nevertheless, the elaboration and use of specific anti-DMV Abs might be essential to guarantee conclusive results in diagnostic and pathogenetic investigations.
Constructing the myth of protest masculinity in Chinese English language news media
Authors: Yu Yating , Nartey Mark
Published: July 2021

Although the Chinese media’s construction of unmarried citizens as ‘leftover’ has incited much controversy, little research attention has been given to the ways ‘leftover men’ are represented in discourse. To fill this gap, this study performs a critical discourse analysis of 65 English language news reports in Chinese media to investigate the predominant gendered discourses underlying representations of leftover men and the discursive strategies used to construct their identities. The findings show that the media perpetuate a myth of ‘protest masculinity’ by suggesting that poor, single men may become a threat to social harmony due to the shortage of marriageable women in China. Leftover men are represented as poor men, troublemakers and victims via discursive processes that include referential, predicational and aggregation strategies as well as metaphor. This study sheds light on the issues and concerns of a marginalised group whose predicament has not been given much attention in the literature.
‘It is this ignorance we have to fight’
Authors: Katsiveli Stamatina
Published: July 2021

Growing legal LGBTQI+ representation in Greece is systematically targeted by Greek homophobic and transphobic nationalism, commonly articulated in public by (far) rightwing politicians and church representatives. The present article brings into attention a more subtle way in which discriminatory discourses make their way into the public sphere, disguised behind progressive narratives of inclusivity. I examine an interview with two transgender activists on the occasion of the gender recognition law passed in Greece in 2017. According to the journalist, the interview seeks ‘to fight ignorance’ and, by extension, transphobia. Drawing on conversation analysis and membership categorisation analysis, I identify two discursive strategies through which the journalist disrupts his initial framing: (1) elaborated questions which invoke and assume gender normativity and (2) references to the overhearing audience, which assume (and reproduce) a generalised scepticism regarding transgender identity. This interview instantiates a new powerful genre of politics in disguise which deserves attention and requires nuanced interactional analysis in order to be traced and unpacked.

Described rectifier with twelve output voltage ripple is designed to supply industrial load and power lines DC, and provides savings in material and installation cost savings. A scheme managed rectifier with side pulsations, which gives a gain of up to 30% on mass and dimensions compared to classical schemes with two secondary windings are star-delta and provides better electromagnetic compatibility with the mains. The essence of the method is that the amount of segments of two sine waves results in a segment as a sinusoidal function to the amplitude and phase determined by the amplitude and phase terms. In the case of controlled semiconductor valves in a three-phase bridge circuit, it is possible to obtain an additional phase shift - at the expense of the control algorithm, which is the subject of this article. The total voltage of the two series-connected three-phase bridges (second - controlled with the "side pulsation ") connected to two secondary windings supplying three-phase transformer with a ratio of the number of turns in a ratio of 2.8: 1, respectively, and the same method of switching the two secondary windings with star connection has 12 pulsations.

Published: July 2021

Resumo Sentido de vida é uma variável que tem sido considerada central para compreensão do bem-estar humano nas últimas décadas. Entretanto, o estudo desse conceito é muito mais antigo e ele já recebeu contribuições da filosofia, da psicologia humanista, da logoterapia e, recentemente, da psicologia positiva e da psicometria, o que possibilitou que tal construto fosse mensurado. Este artigo explora os caminhos de sentido de vida enquanto construto ao longo do tempo, discutindo as contribuições que o conceito recebeu de diversas teorias psicológicas, incluindo o recente modelo tripartite de sentido de vida. Por fim, são discutidos os desafios enfrentados por pesquisadores e clínicos que buscam trabalhar com essa variável.

ABSTRACT: Plants of the genus Brachiaria, used in several countries as forage, are poisonous to some livestock species. Their toxic principle is protodioscin, and the main form of clinical presentation of the toxicosis is hepatogenous photosensitization. Here we compare protodioscin levels in B. decumbens and B. brizantha and review the literature on the concentrations and methodologies of collection and analysis of the toxic principle in Brachiaria spp. and the risk of contamination of pastures by more toxic species that may facilitate poisoning by plants of this genus in sheep. The experiment was conducted in pastures originally formed by B. brizantha, with many B. decumbens invasion points. The occurrence of cases of poisoning by Brachiaria spp. was the criterion for confirming pasture toxicity. The forage samples were collected at ten random points every 28 days through manual grazing simulation. The samples were analyzed for protodioscin by high-performance liquid chromatography (HPLC) with light scattering by evaporation (ELSD) after being dried and crushed. In the flock of 69 sheep, five poisoning cases occurred, three sheep died, and two recovered. The protodioscin levels found in the evaluated pastures ranged from 0.70 to 0.45%; higher levels appeared in B. decumbens (7.09%) compared to 1.04% in B. brizantha. We suggest that Brachiaria spp. should be avoided in pastures where sheep are grazing.
BODY AND SENSES IN ORGANIZATIONAL RESEARCH: EMPATHIC UNDERSTANDINGFROM AN EMBODIED EXPERIENCE
Authors: FERREIRA TATIANE A. , FANTINEL LETÍCIA D. , AMARO RUBENS DE A.
Published: July 2021

ABSTRACT Purpose: The purpose of this paper is to discuss the contributions of the method of empathic understanding to the field of Organizational Studies by highlighting the corporeality and sensitivity of the researcher in the production and interpretation of data. Originality/value: Since empathic understanding can be viewed as a method for analyzing the researcher’s experience during fieldwork, this paper situates the role of the researcher’s body as an instrument for the collection of data during their research. The theory of organizational aesthetics is taken as a basis to discuss the relevance of the sensory dimension during the research process. Without giving priority to any particular sense (such as that of sight, for example), the construction of scientific knowledge is therefore discussed in terms of the human senses that respond to diverse stimuli by highlighting the relevance of the processes involved in the production of embodied and sensible knowledge for Organizational Studies. Design/methodology/approach: A theoretical-empirical study of qualitative nature was carried out in a street market of a Brazilian city. The method of empathic understanding directed the entire process of data collection and analysis, in which the limitations of field observations were discussed by expanding the notion of the researcher’s own experience into that of a sensory experience. Findings: The findings suggest that it is possible for the researcher to engage their mind and body during research by experiencing the field and overcoming dichotomies such as cognition/sensitivity. Such an engagement can be viewed as a major contribution of the method of empathic understanding to Organizational Studies. Thus, the notion of the body as a major vehicle for the construction of knowledge is made evident in this paper through both the discussion of the empathic understanding approach and the research carried out.
MECHANISMS FOR RISK ELIMINATION OF A COMPLIANCE TRAP IN THE BRAZILIAN TELECOMMUNICATIONS INDUSTRY
Authors: SANA GUILHERME A. , GUARIDO FILHO EDSON R.
Published: July 2021

ABSTRACT Purpose: This study aims to analyze how the Brazilian National Communications Agency (Agência Nacional de Telecomunicações – Anatel) and cellular operators in Brazil used ceremonial and discursive practices to build enforcement and compliance actions, adopted during a period of crisis in the cellular sector industry in 2012 when the legitimacy of the respective regulatory model and the regulatory agent were challenged, shaping a compliance trap situation. Originality/value: The work fills a theoretical gap by associating the normative-cultural perspective of regulation associated with organizational institutionalism, based on the assertion that the relationship between regulator and regulated is interactive and not unidirectional, allowing that enforcement mechanisms represent political efforts, realigning the interests of the actors within their institutional environments. Design/methodology/approach: The case study research strategy with a qualitative approach is adopted, studying the 2012 crisis in the cellular sector industry, with the collection of data from documentary sources and semi-structured interviews with participants in the process. Findings: The results show that, in the compliance trap situation, symbolic criteria can appropriate the speeches, producing texts and practices in favor of legitimizing the enforcement mechanisms and the respective compliance responses in view of the audience. Therefore, the compliance trap risk on the regulatory agent is mitigated to the extent that ceremonial and discursive practices manifest themselves responsively and gain political and cultural support, reducing social pressure on the legitimacy of the regulation model.

ABSTRACT Objective: identify adherence to patient safety recommendations in the vaccination room. Method: this is a cross-sectional study that analyzed 463 vaccination procedures in six vaccination rooms in Minas Gerais from June to July 2018. Data were obtained with the application of the Patient Safety Checklist for Vaccination Rooms through systematic observation of the vaccination procedure. Descriptive statistics were used for data analysis. Results: 463 vaccination procedures were observed, and the mean overall adherence score was 58.5%, min. 43.3% and max. 74.1%. The items of higher adherence were related to the records of vaccine data (name, date, and batch) on the vaccination card; vaccine application with dose, route of administration, location and correct materials; and records in an information system. The items of lower adherence were related to health guidance; investigation of adverse events following immunization and the health status of the vaccinated person; records of vaccine laboratory and vaccination center on the vaccination card; vaccine workforce handwashing; and proper vaccine preparation. Conclusion: the mean overall score found in this study was 58.5% for the adherence to recommendations for vaccination procedures. This result highlights the need for educational interventions that promote patient safety in the vaccination room and studies analyzing the factors that prevent such adherence.
