Authors: Hou Yajing , Wang Yong , Sun Xiaojing , Lou Yake , Yu Ying , Zhang Tong
Published: October 2021

Purpose: We aimed to investigate the effectiveness of suprascapular nerve block (SSNB) in patients with hemiplegic shoulder pain (HSP).

Background: SSNB is widely used in various shoulder pains, but whether it is effective in HSP remains unknown.

Methods: PubMed, Cochrane Library, and Embase databases were searched to identify potential citations. Randomized controlled trials meeting the eligible criteria were included in our analysis. The primary endpoint was Visual Analog Scale (VAS) with a maximum value of 100 and a minimum value of 0. Secondary endpoints were passive range of motion (PROM) that pain starts, and the PROM mainly included abduction, flexion, and external rotation. In addition, the upper extremity Fugl-Meyer assessment (FMA) was also included in our secondary endpoints.

Results: Eight studies with 281 patients were included in our analysis. For VAS, there was no obvious difference between SSNB group and control group regardless of the follow-up period (<4 weeks or ≥4 weeks), which were −6.62 (−15.76, 2.53; p = 0.16) and 1.78 (−16.18, 19.74; p = 0.85). For shoulder function, the PROM of abduction, flexion, and external rotation was similar between groups. However, motor function indicator FMA is lower in SSNB control than that in control group, with a mean difference (and 95% CI) of −2.59 (−4.52, −0.66; p = 0.008).

Conclusion: SSNB is an effective way for HSP patients.

Authors: Spilka Jared M. , O'Halloran Conor P. , Marino Bradley S. , Brady Kenneth M.
Published: October 2021

The autoregulation of cerebral blood flow protects against brain injury from transient fluctuations in arterial blood pressure. Impaired autoregulation may contribute to hypoperfusion injury in neonates and infants. Monitoring cerebral autoregulation in neonatal cardiac surgery as a guide for arterial blood pressure management may reduce neurodevelopmental morbidity. Cerebral autoregulation monitoring has been validated in animal models and in an adult trial autoregulation monitoring during bypass improved postoperative delirium scores. The nuances of pediatric cardiac disease and congenital heart surgery make simply applying adult trial findings to this unique population inappropriate. Therefore, dedicated pediatric clinical trials of cerebral autoregulation monitoring are indicated.
Personal Resources and Organizational Outcomes: Sex as a Moderator of the Complex Relationships Between Self-Esteem, Heart Rate Variability, and Work-Related Exhaustion
Authors: De Longis Evelina , Ottaviani Cristina , Alessandri Guido
Published: October 2021

Global self-esteem represents a protective personal resource lowering the risk of psychological distress. Research conducted in the work setting has confirmed the psychosocial benefits of high self-esteem. However, research linking self-esteem to neurobiological adaptability appears quite scarce. In this study, we propose a theoretical model in which self-esteem predicts work-related exhaustion indirectly, through the mediation of heart rate variability (HRV) and negative affect at work. Moreover, we explore the relationship between self-esteem and HRV. From one side, one would expect a positive link between self-esteem and HRV, signaling higher autonomic adaptability. However, recent studies have shown that in women, such associations become more complex, with even reversed patterns as compared with that in men. Thus, we included sex as a moderator of the relationship between HRV and self-esteem. The model was tested on a sample of 110 individuals working in the relational professions (54% males; Mage = 42.6, SD = 13.73), observed for an entire workday. Results confirmed the protective role of self-esteem against the experience of negative affect and (indirectly) work-related exhaustion. Symptoms of exhaustion at work were also negatively predicted by HRV, and both HRV and negative affect acted as mediators of the relationship between self-esteem and work-related exhaustion. Notably, sex differences emerged in the association between global self-esteem and cardiac vagal tone at work: in women, self-esteem was negatively related to HRV, which in turn led to higher work-related exhaustion, whereas in men, no evidence of this indirect effect appeared. Burnout prevention programs should not ignore important sex differences in how individuals respond to work-related stress.

Published: October 2021

Iron regulatory protein 2 (IRP2) deficiency in mice and humans causes microcytic anemia and neurodegeneration due to functional cellular iron depletion. Our previous in vitro data have demonstrated that Irp2 depletion upregulates hypoxia-inducible factor subunits Hif1α and Hif2α expression; inhibition of Hif2α rescues Irp2 ablation-induced mitochondrial dysfunction; and inhibition of Hif1α suppresses the overdose production of lactic acid derived from actively aerobic glycolysis. We wonder whether Hif1α and Hif2α are also elevated in vivo and play a similar role in neurological disorder of Irp2–/– mice. In this study, we confirmed the upregulation of Hif2α, not Hif1α, in tissues, particularly in the central nervous system including the mainly affected cerebellum and spinal cord of Irp2–/– mice. Consistent with this observation, inhibition of Hif2α by PT-2385, not Hif1α by PX-478, prevented neurodegenerative symptoms, which were proved by Purkinje cell arrangement from the shrunken and irregular to the full and regular array. PT-2385 treatment did not only modulate mitochondrial morphology and quality in vivo but also suppressed glycolysis. Consequently, the shift of energy metabolism from glycolysis to oxidative phosphorylation (OXPHOS) was reversed. Our results indicate that Irp2 depletion-induced Hif2α is, in vivo, in charge of the switch between OXPHOS and glycolysis, suggesting that, for the first time to our knowledge, Hif2α is a clinically potential target in the treatment of IRP2 deficiency-induced neurodegenerative syndrome.
Evolutionary Multitasking-Based Multiobjective Optimization Algorithm for Channel Selection in Hybrid Brain Computer Interfacing Systems
Authors: Liu Tianyu , Xu Zhixiong , Cao Lei , Tan Guowei
Published: October 2021

Hybrid-modality brain-computer Interfaces (BCIs), which combine motor imagery (MI) bio-signals and steady-state visual evoked potentials (SSVEPs), has attracted wide attention in the research field of neural engineering. The number of channels should be as small as possible for real-life applications. However, most of recent works about channel selection only focus on either the performance of classification task or the effectiveness of device control. Few works conduct channel selection for MI and SSVEP classification tasks simultaneously. In this paper, a multitasking-based multiobjective evolutionary algorithm (EMMOA) was proposed to select appropriate channels for these two classification tasks at the same time. Moreover, a two-stage framework was introduced to balance the number of selected channels and the classification accuracy in the proposed algorithm. The experimental results verified the feasibility of multiobjective optimization methodology for channel selection of hybrid BCI tasks.

Published: October 2021

Optogenetic technology provides researchers with spatiotemporally precise tools for stimulation, sensing, and analysis of function in cells, tissues, and organs. These tools can offer low-energy and localized approaches due to the use of the transgenically expressed light gated cation channel Channelrhodopsin-2 (ChR2). While the field began with many neurobiological accomplishments it has also evolved exceptionally well in animal cardiac research, bothin vitroandin vivo. Implantable optical devices are being extensively developed to study particular electrophysiological phenomena with the precise control that optogenetics provides. In this review, we highlight recent advances in novel implantable optogenetic devices and their feasibility in cardiac research. Furthermore, we also emphasize the difficulties in translating this technology toward clinical applications and discuss potential solutions for successful clinical translation.

Authors: Szymczak Robert K. , Grzywacz Tomasz , Ziemann Ewa , Sawicka Magdalena , Laskowski Radosław
Published: October 2021

Background: The influence of high altitude on an organism’s physiology depends on the length and the level of hypoxic exposure it experiences. This study aimed to determine the effect of a prolonged sojourn at very high altitudes (above 3,500m) on subsequent sea-level physical performance, body weight, body composition, and hematological parameters.

Materials and Methods: Ten alpinists, nine males and one female, with a mean age of 27±4years, participated in the study. All had been on mountaineering expeditions to 7,000m peaks, where they spent 30±1days above 3,500m with their average sojourn at 4,900±60m. Their aerobic and anaerobic performance, body weight, body composition, and hematological parameters were examined at an altitude of 100m within 7days before the expeditions and 7days after they descended below 3,500m.

Results: We found a significant (p<0.01) decrease in maximal anaerobic power (MAPWAnT) from 9.9±1.3 to 9.2±1.3W·kg−1, total anaerobic work from 248.1±23.8 to 228.1±20.1J·kg−1, anaerobic threshold from 39.3±8.0 to 27.8±5.6 mlO2·kg−1·min−1, body fat mass from 14.0±3.1 to 11.5±3.3%, and a significant increase (p<0.05) in maximal tidal volume from 3.2 [3.0–3.2] to 3.5 [3.3–3.9] L after their sojourn at very high attitude. We found no significant changes in maximal aerobic power, maximal oxygen uptake, body weight, fat-free mass, total body water, hemoglobin, and hematocrit.

Conclusion: A month-long exposure to very high altitude led to impaired sea-level anaerobic performance and anaerobic threshold, increased maximal tidal volume, and depleted body fat mass, but had no effect on maximal aerobic power, maximal oxygen uptake, or hemoglobin and hematocrit levels.
Mother–Child Reminiscing About Emotionally Negative Events and Children’s Long-Term Mental Health
Authors: Koh Jessie Bee Kim , Wang Qi
Published: October 2021

The present study examined the longitudinal relation between mother–child reminiscing of emotionally negative events and children’s mental health. European-American and Chinese-American mothers discussed with their 4.5-year-old children an event that was emotionally negative to the child. At age 7, children’s mental health was assessed, including measures for externalizing problems, internalizing problems, negative social self (an Asian-salient dimension of depression), behavioral problems, and socially adaptive behavior. Independent of culture, maternal reference to negative emotional terms was related to fewer externalizing, internalizing, and behavior problems in children. Maternal attribution of emotions to children was associated with lower negative social self in children. Maternal explanation of children’s emotions was linked to fewer externalizing problems and lower negative social self in children, and maternal reconfirmation of the explanations was related to fewer externalizing and behavioral problems in children. In contrast, maternal attribution of emotions to other people was associated with more externalizing problems and higher negative social self in children of both cultures. Some important cultural differences emerged. Chinese-American mothers’ mention of negative emotional terms was linked to lower negative social self in children, and Chinese-American mothers’ reconfirmation of explanation was related to more socially adaptive behaviors in children. No such relations were found in the European-American sample. The findings underscore the importance of family emotional reminiscing for children’s long-term well-being and the role of culture in shaping the process.

Published: October 2021

Middle Eastern students seeking academic degrees in the US universities often experienced array of challenges in multiple levels as they adjust to the new environments. The current study investigated some of the psychosocial factors affecting their adjustments, namely: age, gender, and marital status. Quantitative method was used to collect data in which a survey was distributed and later analyzed for 92 Middle Eastern participants. The results of the study reveal the followings: (1) age was a significant factor impacting the level of adjustment at α = 0.0001, (2) gender on the other hand was not statistically significant as there was no difference between males versus females on the level of adjustment, (3) results also revealed that marital status had a statistically significant impact in which married participants displayed a higher level of adjustment than singles, and (4) with the current changes in the social lives and gender roles in the Middle East, further investigations are opened for exploration.
Comparing Students’ Engagement in Classroom Education Between China and Germany
Authors: Deng Shu
Published: October 2021

Since the mid-1980s, there has been an academic shift toward students’ involvement in the learning process. A great number of studies have focused on the relationship between student engagement and educational achievement. They have highlighted that appropriate educational input and a supportive classroom environment are necessary, but optimum learning should occur when students are engaged with the curriculum as well as the institution, particularly in higher education institutions. Many scholars claimed that higher levels of engagement will help students deal with academic anxiety and develop a sense of belonging, which may lead to higher academic success. Educational experts and policymakers have begun to propose nationwide and international strategies and programs to promote student engagement in the classroom, which has led to the proposal of well-known programs such as the National Survey of Student Engagement, the UK Engagement Survey, and Program for International Student Assessment. Such engagement-centered international measures have been used across the globe (e.g., Germany) and translated into different languages (e.g., Chinese). Although the findings of relevant studies confirm the effectiveness of engagement on learning achievement, there is still the need to conduct further (cross-sectional) studies considering the implementation of such programs in a different context. The present study is an attempt to review the related literature regarding student engagement among Chinese and German students across a variety of disciplines. The findings suggest that researchers should devote more time and budget to investigate the significance of learner engagement, especially in Germany and China.

Authors: Sun Xianyi , Li Jiao , Meng Lan
Published: October 2021

Emotions are one of the pillars of all human beings which can play a vital role in providing education. Emotions can affect all aspects of education. The feeling of creativity is one of the subsets of emotions. This feeling strongly affects the performance of education and the level of involvement of students. Student involvement has different aspects: social aspect; individual aspect, and emotional aspect. The present review shows that the emotional aspect of L2 engagement plays a pivotal role in the process of learning the language in English as a foreign language (EFL) and English as a second language (ESL) context. In dealing with the emotional aspect of teachers, the personal, social, and environmental aspects of the individual should be considered. The paper concludes with some pedagogical implications and provides some suggestions for future research.

Published: October 2021

Evidence-based practice is the foundation of rehabilitation for maximizing client outcomes. However, an unacceptably high number of ineffective or outdated interventions are still implemented, leading to sub-optimal outcomes for clients. This paper proposes the Rehabilitation Evidence bAsed Decision-Making (READ) Model, a decision-making algorithm for evidence-based decision-making in rehabilitation settings. The READ Model outlines a step-by-step layered process for healthcare professionals to collaboratively set goals, and to select appropriate interventions. The READ Model acknowledges the important multi-layered contributions of client's preferences and values, family supports available, and external environmental factors such as funding, availability of services and access. Healthcare professionals can apply the READ Model to choose interventions that are evidence-based, with an appropriate mode, dose, and with regular review, in order to achieve client's goals. Two case studies are used to demonstrate application of the READ Model: cerebral palsy and autism spectrum disorder. The READ Model applies the four central principles of evidence-based practice and can be applied across multiple rehabilitation settings.

Published: October 2021

In badminton, the ability to quickly gather relevant visual information is one of the most important determinants of performance. However, gaze behavior has never been investigated in a real-game setting (with fatigue), nor related to performance. The aim of this study was to evaluate the effect of fatigue on gaze behavior during a badminton game setting, and to determine the relationship between fatigue, performance and gaze behavior. Nineteen novice badminton players equipped with eye-tracking glasses played two badminton sets: one before and one after a fatiguing task. The duration and number of fixations for each exchange were evaluated for nine areas of interest. Performance in terms of points won or lost and successful strokes was not impacted by fatigue, however fatigue induced more fixations per exchange on two areas of interest (shuttlecock and empty area after the opponent's stroke). Furthermore, two distinct gaze behaviors were found for successful and unsuccessful performance: points won were associated with fixations on the boundary lines and few fixation durations on empty area before the participant's stroke; successful strokes were related to long fixation durations, few fixation durations on empty area and a large number of fixations on the shuttlecock, racket, opponent's upper body and anticipation area. This is the first study to use a mobile eye-tracking system to capture gaze behavior during a real badminton game setting: fatigue induced changes in gaze behavior, and successful and unsuccessful performance were associated with two distinct gaze behaviors.

The microbial contamination of pork during the slaughter process, especially that of the hygiene indicator bacteria, Escherichia coli, is closely related to the safety and quality of the meat. Some diarrheagenic E. coli can cause serious foodborne diseases, and pose a significant threat to human life and health. In order to ascertain the current status of E. coli and diarrheagenic E. coli contamination during the pig slaughter process in China, we conducted thorough monitoring of large-sized slaughterhouses, as well as small- or medium-sized slaughterhouses, in different provinces of China from 2019 to 2020. The overall positive rate of E. coli on the pork surface after slaughter was very high (97.07%). Both the amount of E. coli contamination and the positive ratio of diarrheagenic E. coli in large-sized slaughterhouses (7.50–13.33 CFU/cm2, 3.44%) were lower than those in small- or medium-sized slaughterhouses (74.99–133.35 CFU/cm2, 5.71%). Combined with the current status of sanitary control in slaughterhouses, we determined that pre-cooling treatment significantly reduced E. coli and diarrheagenic E. coli in pork after slaughter, while microbiological testing reduced E. coli. Based on our monitoring data, China urgently needs to establish relevant standards to better control microbial contamination during pig slaughtering progress. This study provided a theoretical basis for the hygiene quality management of the pig slaughter industry in China.

Published: October 2021

The article is devoted to the issues of mining and pretreatment of the column and the pedestal in the Piterlak quarry, loading the column on a barge and delivery to St. Petersburg. The basis for the article is an album of illustrations of the rise of the Alexander Column, made by A. Montferrand and a literary review. The admiration of many architectural structures of the 18th-19th centuries is caused by the question of how this could be done at that time, without the power of steam and electricity. There are no such questions about the constructions built after the middle of the 19th century -there were already many lifting mechanisms, photography documented the construction process, and the dug Suez Canal testified to the increased capabilities of humanity and strengthened engineering skills. No one doubts that the Eiffel Tower was built without the use of helicopters and the achievements of an antediluvian civilization, but in relation to the unique creation of A. Montferrand, i. e. the Alexander Column in St. Petersburg, there is a clear distrust in the reality of the achieved result — the column of more than 27 meters high, more than 3 meters in diameter and weighing more than 600 tons stands vertically on the end surface without additional supporting structures. This article, presented in three reports, is devoted to the attempt to mathematically justify the possibility of what was achieved at the level of knowledge, skills, mechanisms and technologies of the beginning of the 19th century.

Published: October 2021

Modern trends in the development of technology are based mainly on successful engineering activities. The combination of the most modern computer technologies and the traditions of using a pencil, drawing, drafts, and, of course, a living fruitful thought is a guarantee of the education of a genuine Engineer. On the one hand, educational technologies in engineering universities at the initial stage should be based, in our deep conviction, on school geometry. On the other hand, descriptive geometry and engineering graphics should contain examples for immersion in the chosen specialty. By order of the Ministry of Education and Science of the Russian Federation, engineering classes, in which lecturers of technical universities were involved, were organized 10 years ago in Moscow schools. The creation of engineering classes is caused by the need to instill in students an interest in the engineering profession. To successfully solve this problem, it is necessary to increase the level of students» knowledge in geometry and drawing. On the basis of these subjects, one should develop design skills and skills of using computer modeling tools. The result of this cooperation should be the involvement of schoolchildren to participate in competitions and olympiads. The Department of Engineering Graphics, Bauman Moscow State Technical University, has accumulated 30 years of experience in cooperation with specialized schools in order to develop students» interest in the engineering profession. The article provides an example of the introduction of a common cutting tool, i. e. a drill, which demonstrates the depth of engineering thought formed over a thousand-year history, into the educational process when studying geometry at school and descriptive geometry at a technical university. The drill as an object comprehensible to first-year students is used to provide the basic knowledge of descriptive geometry. In addition, the problem related to the improvement of the technology of end-to-end training throughout the course of obtaining an engineering education is touched upon.

Published: October 2021

A large number of works are devoted to the development of the skin and hair cover of sheep, depending on their breed affiliation, age, feeding conditions and housing. The authors point out that along with other conditions the quality of wool and wool clip is greatly influenced by the conditions of the feeding of animals. A high level of feeding increases the wool clip and improves the quality of the wool and vice versa a low level reduces, causes thinning and worsens other physical properties of the wool. As is known, one of the significant factors that determine the increase in wool clip is the size of the animal and, consequently, the total area of the skin. The purpose of the research was to investigate the morphological traits of the development of the skin and wool cover in sheep of Prikatunsky meat and wool type. The research material was wool samples from four topographic areas of the animal’s body (side/thigh/back/belly) and skin (side) of different sex and age groups, selected from the animals of the studied groups. In the course of research, the quality of wool and indicators of the histostructure of the skin of Prikatunsky meat and wool type of sheep have been investigated. In terms of thick-haired of wool, replacement rams and gimbers of Prikatunsky meat and wool type of sheep were superior by 4,82 pcs. per mm² or 19,0 % and 4,41 pcs. per mm² or 15,8 % of adult animals, respectively. Balance secondary follicles/primary follicles in young animals were higher by 10,3 and 17,3 % compared to breeding rams and ewes. The wool of the replacement young animals was thinner by 7,28 and 4,78 microns and they were more thick-haired. The obtained data will be used in the mating campaign when mating program rams in order to improve the sheep of Prikatunsky meat and wool type.

Published: October 2021

In order to effectively provide the body of cows with energy during the increasing the milk yield without the risk of acidosis, progressive animal breeders of the Altai Territory include wet flattened corn grain in the composition of concentrated feed. The question of the expediency and economic effectiveness of using wet flattened corn grain for cows of various physiological groups – first-calf heifers and mature animals continues to be debatable. Therefore, a comparative assessment of two options for feeding wet flattened corn grain to cows under the conditions of the Altai Territory is considered promising in modern animal husbandry and is of great practical interest. The purpose of the work was to identify the optimal and economically feasible option for using wet flattened corn grain in the rations of lactating cows. When using wet flattened corn grains in an amount of 7,1 % of the nutritional value of the ration the first-calf heifers during the period of increasing the milk yield, productivity has increased by 20,9 %. The average daily milk yield was 17,3 kg, which significantly exceeded the indicator of the control group (P > 0,95). The inclusion of wet flattened corn grains in the ration of mature cows in the amount of 1 kg for 30–35 days before calving, then 4,5 kg from 15 to 75 days after calving allows us to get the average daily milk yield of 30 kg or 20,3 % higher than that of the control group of herdmates (P > 0,95). The effectiveness of the use of wet flattened corn grain had significant indicators: the total profit from the sale of dairy products of the first-calf heifers of the experimental group amounted to 16 251,3 rubles/head, and from the sale of milk of mature cows of the experimental group it was 30 346,43 rubles/head.

Published: October 2021

This article is devoted to the analysis of cognitive distortion in the mass media as a method of forming a civic identity. Due to the increasing influence of mass media and information technologies, the growth of information impact, the problem of the formation of civil identity is becoming more and more significant, and the mass media is a tool for the formation of civil identity. The authors consider the method of cognitive distortion in the mass media as a method of forming a civic identity in modern media. Culture in the Russian and Chinese traditions reveals both universals and peculiarities. The authors analyze how the attitude to civil identity is transmitted in Russian and Chinese media discourses, which allows us to understand the difference in background knowledge and identify cognitive distortions in translation. The authors see differences in the ethnopedagogic strategies of the state that ensure a positive attitude to civic identity in the Chinese digital space, which has parallels with the Soviet discourse. At the same time, the authors believe that the assimilation of Western models of admiration for their values has a negative impact on the formation of generational continuity and ethno-socio-cultural experience in the traditions of countries.

Published: October 2021

The object of the research includes the actual designations of the subject with the semantics of enmity, formed with the active foreign language word-formation components, functioning in Russian-language online media and Internet communication in 2000-2020. The approaches used include system-centric and text-centric, semasiological and onomasiological approaches, motivational, definitional, functional-semantic and contextual analysis. It analyses the syntagmatics, semantics, word's inner form, type of motivation, motivational form and meaning, motivational and classification features, lexical and structural motivators, ways of discursive actualising the motivational relations of the studied words. It is shown that selected lexical units with the component –phobe, -phrenic, - saur, -down, -hater, -oid, -oholik, -path, -man, -(e)rast belong to the vocabulary of enmity depending on their significative or pragmatic component, implement a negative assessment of intellectual, psychological, moral qualities of the subject. The actual vectors of developing the nominal vocabulary of enmity in the Russian language are determined by integration, intensification, internationalization, intensification. The relevant word-forming tendencies in the studied group of nouns are highlighted – the frequency of word composition, non-usual ways of word formation, nominations by analogy, the increasing role of onyms, the activity of word-forming components with a negative rating. It is demonstrated that motivational relations of lexemes are discursively implemented through the actualization of lexical and structural motivation, the paradigmatic value of lexemes, the subjective modality that the addressee uses, his/her individual motivation of words.

Published: October 2021

The objective of the article is a comprehensive analysis of the problem of interpretation of contractual relations and their management into the legal field of the national legislation to achieve the significant reduction of corruption at the municipal level on the territory of our country. To achieve this objective, a set of philosophical-worldview, general scientific (analysis, synthesis) and special-scientific methods (systemic, structural-functional, comparative-legal) have been used. It is proved that lobbying is a subjective factor that affects the process of municipal legal regulation. Emphasis is placed on the expediency of introducing the contractual form of regulation of relations on lobbying management decisions at the municipal level. The contract on lobbying at the municipal level is defined as a multilateral agreement between the customer, lobbyist and the body of local government, which has a public-law character, establishes contractual rules of law on lobbying to influence the process of adopting normative municipal-legal acts. It is concluded that it is extremely important to organize and regulate lobbying in any country in the world, because if this phenomenon cannot be completely eradicated, it must be regulated from the legal point of view, which, in the end, will significantly reduce the level of corruption in the society.

Os Ensaios Não Destrutivos (END) são técnicas utilizadas na inspeção de materiais de equipamentos sem danificá-los, sendo executadas nas etapas de fabricação, de construção, de montagem e de manutenção. Nesse trabalho foi desenvolvido um protótipo para a utilização em ensaios não destrutivos, através de aplicação de correntes parasitas, a fim de descobrir a descontinuidade na superfície de uma peça padrão. Para realizar esses estudos foi utilizado um sensor de efeito Hall e um controlador Arduino, que servirá para a leitura e análise dos dados gerados. Também foi utilizado um imã para gerar os campos magnéticos que irão induzir as correntes elétricas na superfície e no interior da peça. Desta forma, atingiu-se o objetivo de criar um sistema capaz de fazer os ensaios não destrutivos em peças metálicas, com baixo custo e facilidade de interpretação.

The ossifying fibroma (OF) is characterized as a benign neoplasm originated from the mesenchymal periodontal membrane, being composed of different amounts of mineralized material and fibrocellular stroma, leading to a mixed aspect. More commonly found as solitary lesions, the OF can be multiple in rare cases, normally associated with hyperparathyroidism-jaw tumor syndrome (HPT-JT). The aim of this study is to report a case of bilateral OF in the mandible with different stages of maturation, not associated with HPT-JT. This case shows a 20-year-old female patient with asymptomatic intraoral hard swelling in both sides of the mandible, presenting a slight expansion in the buccal bone cortex, near to the molars, hard to palpation. CBCT showed a unilocular, well-circumscribed hypodense image, with calcified masses only on the right side. Incisional biopsies were performed and a diagnosis of bilateral OF was reached. Due to the different stages of maturation of the lesions, two different surgical approaches were performed, curettage in the left side and surgical resection in the right side with extraction of the lower second premolar and lower first molar. These areas were restored with bone grafts and the left first molar was unresponsive to the pulp vitality test and endodontic treatment was performed. The patient is undergoing periodic clinical and radiographic follow-up, and after 12 months no signs or evidence of recurrence were observed.
Effect of fat and thickener on physicochemical, textural and sensory properties of lactose-free Petit-Suisse cheese made from sheep milk / Efeito da gordura e do espessante nas propriedades físico-químicas, texturais e sensoriais do queijo Petit-Suisse sem lactose feito de leite de ovelha

The aim of this study was to develop a Petit-Suisse cheese with different concentrations of fat and thickener using a differentiated milk matrix: sheep milk. A central composite design was used to analyze the effects of fat and thickener concentrations on the properties of the cheese. Fat exerted an influence on ash (1.20 to 1.50%) and pH (5.46 to 5.78). Fat and thickener affected elasticity, firmness and gumminess. The quantitative descriptive analysis revealed that the best formulation was 8% fat and 1% thickener. Petit-Suisse cheese made from lactose-free sheep milk is viable with medium concentrations of fat and thickener.
VLCD diet - Dietkcal® (very-low-calorie diet) and its influence on anthropometric and metabolic variations in obese patients Running Head: Influence of Dietkcal® in obese patients / Dieta VLCD - Dietkcal® (dieta muito baixa em calorias) e sua influência sobre as variações antropométricas e metabólicas em pacientes obesos Running Head: Influência do Dietkcal® em pacientes obesos

VLCD (dieta de muito baixa caloria) são definidas como dietas de baixa caloria que fornecem entre 450 a 800 kcal por dia e, dada a relevância do VLCD no contexto da obesidade, este estudo realizou uma análise comparativa de pacientes que usaram a dieta VLCD (Dietkcal®) antes e após um período de dois meses, sobre seus parâmetros antropométricos. Trata-se de um estudo descritivo, retrospectivo, quantitativo, com utilização do método de pesquisa documental. Os resultados mostraram que uma perda de peso média correspondente a 7,4 kg pode ser observada no período de dois meses, apresentando significância estatística entre os pesos inicial e final. Em relação aos valores obtidos a partir do percentual de gordura, observamos uma perda total estatisticamente significante de 4,53% no período de dois meses. Em relação à diferença apresentada na circunferência da cintura dos pacientes, observou-se diminuição de 2,5 cm no total de dois meses, o que é estatisticamente significativo. O presente estudo contribui trazendo resultados em que uma dieta VLCD pode resultar em perda acentuada de peso, podendo favorecer o perfil metabólico dos pacientes, como a diminuição do percentual de gordura corporal e circunferência da cintura, uma melhora na saúde e qualidade de vida desses pacientes também pode ser destacada.

O cena?rio mundial foi modificado com o surgimento da doença causada pelo novo coronavírus, que pelo alto potencial de contágio alcançou níveis de transmissão generalizada e foi reconhecida como uma pandemia pela Organização Mundial da Saúde. O objetivo deste trabalho foi avaliar a prevalência dos sintomas de ansiedade e depressão nos profissionais de saúde em meio à pandemia da COVID-19 e comparar quais foram as classes mais afetadas. Um questionário online composto de 21 questões foi divulgado para os profissionais da saúde de todo o território brasileiro através das redes sociais entre abril e maio de 2020. Para a análise dos dados coletados, foram utilizados métodos de estatística descritiva e inferencial. Foram coletadas informações de 402 participantes. O estudo sugere a prevalência de sintomas de depressão e ansiedade na maioria dos trabalhadores da área da saúde, principalmente na classe dos médicos, dentistas e enfermeiros. O reconhecimento dos sintomas e o planejamento de intervenções que visem reduzir danos à saúde mental dos profissionais de saúde durante e após a pandemia de COVID-19 são fundamentais para a garantia do bem-estar desses indivíduos.

The COVID-19 disease has as its etiological agent the SARS-CoV-2, a RNA virus that causes severe respiratory syndrome. Diabetes mellitus is one of the significant risk factors for COVID-19 due to the weakened immune response of these patients and widely distribution of ACE2 in diferent organs. ACE2 is a receptor that antagonizes the RAS system, and is  related to the clinical symptoms of COVID 19 .Its expression in the islet cells and exocrine pancreas suggest the susceptibility for SARS-CoV 2 infection in diabetic patients. This stydy analyses the infeccional profile of diabetic patients infeccted by COVID-19 in the city of Maceió. A research was performed in the year of 2020-2021 in english idiom in the database PubMed using the descriptors “ACE receptor” AND “Covid”, “Covid” AND “Diabetes” AND “ ACE receptor” .The criteria of inclusion and exclusion established was the relevance and approach based on the theme to be discussed.It was collected data about confirmed deaths by Covid 19 according to preexisting comorbidities in the city of Maceió – AL shown in the graphics , expressing an average mortality among patients infected by Covid and preexisting Diabetes Mellitus. This study shows a reduction in the percentage of mortality in diabetic patients infected by Covid-19 seen in view of the adoption of measures to restrict the spread of the virus, reducing the numbers of infecion, especially the risk group, in addition to the vaccination campaign which culminated in positive results to the reduction in the mortality in infected diabetics.

A gestão estratégica tem como objetivo levantar informações sobre a competitividade da empresa, ameaças, recursos disponíveis, oportunidades, entre outros direcionamentos importantes. Baseado nos dados obtidos é possível pensar em ações e tomar decisões seguindo seu plano estratégico. Dizemos que o processo de gestão estratégica engloba análise de decisões antes de colocá-las em prática, pois antes da alta administração tomar uma decisão é preciso verificar indicadores de desempenho e relatórios gerenciais. A partir desses conceitos, a pesquisa teve como objetivo analisar e diagnosticar a gestão estratégica de uma empresa consolidada do setor siderúrgico. Com base em artigos e documentos disponíveis mediantes a livros e websites foi possível caracterizar a empresa, discutir seu posicionamento em relação à concorrência, identificar objetivos estratégicos e indicadores de desempenho. Para isso foram utilizados dois sistemas de medição, as cinco forças de Potter e a análise SWOT, apresentando e pontuando métodos e ações da empresa tanto como causa e efeito para sua estrutura gerencial e processo estratégico.
