Nodal Tachycardia Induced By Neostigmine Administration During Off-Pump Coronary Artery Bypass Graft Surgery: What Makes the Difference? A Case Report
Authors: Xuena
Published: April 2023

Controlling the heart rate (HR) to a proper level is an important part during off-pump coronary artery bypass graft (CABG) surgery, particularly in two aspects. First, the oxygen consumption during cardiac work could be decreased, which is obviously beneficial for the myocardium suffering from inadequate blood supply. Second, slow heart action makes it easy for surgeons to perform. There are some treatments for lowering HR, where neostigmine is not commonly used but usually effective, which had been discussed more than 50 years ago. However, there are adverse responses that cannot be ignored and are even dangerous, for example, severe bradyarrhythmia and overload of secretion in the trachea. Here, we report a nodal tachycardia case after neostigmine infusion.

Authors: Alizzi Ali , Edwards James , Markou Mark , Sanderson Andrew , Ottens Jane , Polok Darren
Published: April 2023

Background: A 78-year-old male was admitted to our institute with increasing shortness of breath and decreased exercise tolerance. His increasing symptoms were not relieved with medical management. He had a complex medical history that included aortic valve replacement (AVR). Echocardiography showed a deteriorating aortic bioprosthesis with severe aortic regurgitation.
Method: Intraoperative extraction of this prosthesis proved technically challenging and a valve in valve successfully was implanted as a salvage procedure.
Results: The procedure was successful, and the patient made a full recovery.
Conclusion: Open valve in valve implantation, despite technical difficulties, may be utilized as a salvage procedure.
Análisis morfométrico de la cuenca río Santa Lucía (Corrientes, Argentina)
Authors: Smichowski Humberto , Contreras Félix Ignacio
Published: April 2023

In this work, a morphometric study of the Santa Lucia River basin in the province of Corrientes-Ar- gentina was carried out to determine its hydrological response, and to indicate the influence of morphometric factors on the intensification or attenuation of floods, which generates useful data for territorial planning. The results obtained from the quantification and measurement of the parameters show a basin with an elongated shape, relief with high erosive potential, very low slope, and a not very efficient drainage network; from which it is concluded that the basin will have gradual floods but extended in time.
Uso de la tierra en las comarcas del municipio de Zinapécuaro, Michoacán, México
Authors: Aguilar-Sánchez Genaro , Aguilar-Sánchez Daniel
Published: April 2023

This research aims to identify the landscapes that are formed in the municipality of Zinapecuaro, at a scale of 1: 250,000; characterize the appropriation of the landscape made by the inhabitants through its use and propose a better use of differentiated landscapes. The methodology of differen- tiating the territory through complex Towns and Regions is applied and, within them, field work is carried out by comparing their current use with that recommended by the FAO, in its agroecological zoning proposal. It is found that in the municipality of Zinapecuaro there are 4 complex Comarcas and each one of them has several classes of land. In most of the Comarcas and classes of land, the current use, agricultural and livestock, does not correspond to what is recommended by the FAO, since they should have a forestry and conservation use. Due to the above, the change of use of forest land to agriculture and livestock must be controlled, to stop the degradation of soil and vegetation.
Poultry litter physiochemical characterization based on production conditions for circular systems
Authors: Katuwal Sheela , Rafsan Nur-Al-Sarah , Ashworth Amanda J. , Kolar Praveen
Published: April 2023

Poultry litter is a useful product as a fertilizer, energy feedstock for thermochemical conversion, and a precursor for synthesis of adsorbents and catalysts. Detailed characterization of baseline properties is necessary for enhanced environmental and economic utilization of this valuable resource. Baseline physicochemical characterization was carried out at two broiler production facilities (Arkansas, PL1, and North Carolina, PL2). Greater concentrations of inorganic nitrogen, phosphorus, and potassium were obtained for PL1, suggesting greater nutrient value compared to PL2. PL2 had greater carbon content and water-holding capacity than PL1. X-ray photoelectron spectroscopy (XPS) of PL1 and PL2 indicated a similarity between litters in terms of the presence of carbon, nitrogen, and oxygen bonds. Both poultry litters had oxygen, nitrogen, sulfur, and phosphorous functional groups, as confirmed by infrared spectroscopy. Time of flight – secondary ion mass spectroscopy of negative ions also indicated similarity of the surface charge distribution between PL1 and PL2. Overall, poultry litters evaluated had similar surface chemistries, with nutrient composition varying based on rearing conditions, which has implications for downstream use in thermochemical conversion and other value-added products.
SmartNews: An Automatic Approach for Event Detection on Media Platforms
Authors: Hazimeh Hussein
Published: April 2023

Social Media Platforms (SMPs) are currently the leading media data sources in the world; billions of people’s electronic devices have adopted these SMPs for their use. The users ‘ accounts on these platforms generate massive amounts of data daily. Data have become an essential building block for many organizations of different domains. Recently, media organizations started using social media as a principal source to collect data, mainly news. Having recognized the importance of SMPs and data availability, media organizations are not using these data efficiently. Many media organizations still use and analyze internet data, especially from social media, manually, which leads to many disadvantages. This research proposes a more efficient and automated approach to collecting information from social media. Actually, this paper proposes an integrated framework that can extract data from multiple SMPs and merge them, store them, and finally allow media workers to extract fundamental data (events) automatically and smartly from social media. The proposed framework takes input from a query and finds the following information: top tweets, total likes and retweets on this query, user’s identity, sentiment analysis, and finally, the prediction component that can classify if a particular item has classified an event or not. An advantage of this approach is to help media leaders control and track their performance in the media sector and maintain popularity on the internet. The proposed system has been validated on real datasets collected from different data sources. Findings show that this proposed system has remarkable accuracy, precision, and recall results, after evaluating different machine learning algorithms.

Contribution of unparticles to the Møller scattering in the Randall-Sundrum model
Authors: Dang Van Soa , Le Mai Dung , Thủy Đào Thị Lệ
Published: April 2023

The influence of vector, scalar unparticle exchange and photon \((\gamma)\), \(Z\) boson, Higgs-radion \((h,\phi)\) exchange on the fundamental Møller scattering in Randall-Sundrum model is presented. We evaluated the contribution from each exchange in standard model physics and unparticle physics to the final production cross-sections with the apposite energy reach in the current accelerators and colliders. The results indicate that the effect of vector unparticles is larger than its scalar all over the range of collision energy, as much greater than Higgs \((h)\) and radion \((\phi)\) in the low energy. \(Z\) boson exchange also contributes the greatest to the process in both unpolarized and polarized conditions in higher energy regions when compared to photon exchange \((\gamma)\) which normally dominates at the lower energies.

La ciencia se preocupa por la causalidad, buscando comprender la realidad a través de la observación, la verificación y la experiencia. En este sentido, la prueba de hipótesis y la experimentación se consideran métodos científicos. La filosofía se ocupa del propósito de la vida humana, la naturaleza del ser y la realidad, la teoría y los límites del conocimiento, utilizando la intuición, la introspección y el razonamiento como ejemplos de metodologías filosóficas. La ciencia y la filosofía comparten un mismo objetivo, que es aumentar el conocimiento. Así, la ciencia de cualquier disciplina está ligada a su filosofía, la cual proporciona la base para comprender y desarrollar teorías para la ciencia.

Autonomia związków wyznaniowych jako zasada ustrojowa i prawo podmiotowe
Authors:   Uniwersytet Warszawski, Brzozowski Wojciech
Published: April 2023

In the existing body of literature on the autonomy of religious associations, little attention has been paid to the normative nature of the formula adopted in the Polish Constitution, including the relation of the principle of autonomy to freedom of religion and belief. In this article, it is argued that religious autonomy, as expressed in the Polish Constitution, should be understood both as a constitutional principle and as a right of religious associations. The right to autonomy is not absolute and may be subject to limitations, but the closer the connection between the area of autonomy subject to regulation and the spiritual identity of the community concerned, the narrower the scope of permissible interference. The protection of the most sensitive manifestations of religious autonomy is safeguarded by the constitutionnal prohibition of interference with the essence of freedoms and rights.

Authors:   Uniwersytet Mikołaja Kopernika w Toruniu, Perlikowski Łukasz
Published: April 2023

Regime changes that occurred in Great Britain as the effect of Brexit have led to explicit reactivation of the sovereignty of parliament principle. Main warrant of political stability is identified with the Parliament of the United Kingdom. Main hypothesis of this article is that stabilizing activities that are undertaken by this institution influence three possible layers: stabilizing the community, political system and authorities. This overgrowth of competences can affect constitutional fundamentals of the regime. Probable effect of this ongoing process of changes will be endeavours to codify a constitution. Method that is employed in this paper is a method of system analysis, which seems to be the most adequate approach for researches of political stability. Considerations presented in the paper are included within the remit of political theory, political comparativism and constitutional systems.

Authors:   Politechnika Koszalińska, Malużinas Martinas
Published: April 2023

The purpose of this article is to analyze the tasks of the Parliament’s Inspector (Ombudsman) in the Republic of Lithuania. The article takes into account the 2004 Act on Parliament’s Inspectors of the Republic of Lithuania, assessing the most important legal provisions contained in that act. The analysis of the tasks of the inspector of the Parliament of the Republic of Lithuania in the light of the Lithuanian act seems to be an issue worth scientific exploration. In the Polish specialist literature lacks considerations on this subject. The subject of the analysis is still a topical, because Lithuania – similarly to the countries of Central and Eastern Europe – during the political transformation established the institution of the ombudsman, which protects the rights of citizens. The research goal was achieved by using the method of institutional and legal analysis, which was helpful in the analysis of Lithuanian legal acts.

Technology in the present scenario has taken a shape that changed the platform every sector in a unique way, providing better results, accessibility and creation of resources for the next generation. English language has become an important and integral part which acts as a bridge to
collaborate and learn most sought after skills globally. Teaching writing in Indian scenario has been a tough task for language teachers as most of the educational institutions prepare students to perform well in the exams rather than improving student's writing and speaking skills because
of the large-sized classrooms. In this scenario Blended teaching learning approach will be useful for language teachers to increase the student's participation in the activities and access their performance to provide better learning opportunities to the technical students. The availability
of Internet facilities in the institutions and accessibility of teaching learning platforms made the possibility to teach writing skills in Blended mode in Language classroom with more effectiveness that improves the writing skills of technical students. Students active participation in traditional
face to face classes will be followed by well-designed activities will enhance the learning experience and better understanding of writing expository texts in language class room. There are 20 first year B. Tech Engineering students participating in the project. They are taught three classes
per week for Communicative English course offered by the Institute. This paper discuss the possibilities and implications of adopting Blended approach in teaching writing skills to encouraged active student participation and its effectiveness in improving confidence in students.

Workplace English Training
Authors: Shaikh Nikhat Parvez Akhtar
Published: April 2023

In today's global society, business is increasingly conducted across borders, with English often used as the language of international communication. Being able to use English in the workplace has many benefits, including: helping your business succeed, building trust with colleagues
and customers, building and improving international relationships, enhancing skills, earn good salaries and improve international relations through cultural understanding. Workplace cultures and organizations are changing as they adapt to globalization and rapid technological developments.
Likewise, the nature and role of language in work and literacy requirements in the workplace are changing in the face of increasingly multicultural work environments and global networks of communication. Among these changes, recent research has highlighted the role of informal modes of interpersonal
communication in the functioning of the modern workplace. Successful participation in such interactions should not only be seen as a matter of social inclusion but also as a verbal activity. This article reviews current research on the nature of language in the workplace, with particular attention
to the contributions of ethnographic research and language socialization. It then discusses research on four aspects of language content in employment programs: employability skills, interpersonal communication, intercultural openness, and the importance of language and Pedagogy focuses on
job interviews. These soft skills are just as important as your language skills in building lasting business relationships and can help you develop an awareness of cultural differences that can define how you communicate and how to interpret your words
What We Teach Our Children: Gender Sensitivity Within the Indian Curriculum
Authors: Shahiwala Sofiya
Published: April 2023

Equity and Equality are an integral part of any humane society. As a country with norms formulated and bills passed around gender disparity and equal education rights, India has come a long way to be genderinclusive when it comes to educating the youth. However, beyond the admittance
of students in schools, the quality of education imparted to them acts as a measure of the child's development. Despite the tremendous strides in technological and institutional aspects, the Indian curricula still fare poorly in the discourse of gender sensitization. Gender inequality and
societal stereotypes are an integral part of the kind of stories included in the Indian syllabi. The present study looks at the magnitude of gender inclusivity within the Indian curriculum by exploring the English textbooks for grades IX and X prescribed by the National Council of Educational
Research and Training (NCERT). The paper alludes to the United Nations Sustainable Development Goals and the country's efforts in maintaining gender equality in the classroom; and draws a parallel to the content taught in a child's formative years. By analyzing the manner in which gender roles,
stereotypes, heteronormativity, and gender- based binaries are expressed within the highschool textbooks, the study opens up an academic probe into the impact of rigid gender boundaries on a student's mental health.
Language and Globalization: A Critical Study on Language, Culture, and Power Dynamics
Authors: Khan Amirul
Published: April 2023

Since language is a mode of communication that enables individuals from many nations and cultures to understand one another, it plays a crucial part in globalization. Language variety has been significantly impacted by globalization, which has allowed the growth of international languages
and their domination in the political, social, and economic realms. But regrettably, this has resulted in the decline and probable extinction of many endangered languages, especially those that are spoken by tiny, outlying populations. Several nations and international organizations have adopted
English as their official language. It is one of the most widely spoken languages in the world, with an estimated 1.5 billion speakers. It frequently serves as the common language in international trade and diplomacy, which results in a decrease in the usage of other tongues. It predominately
appears in media outlets and on social media platforms, which harms the usage of other languages. Because language may be a weapon for both expressing and resisting power dynamics, language and power become connected once again. By offering speakers of such languages an edge in the political,
economic, and social realms, the development of global languages, especially those of dominating nations, has the potential to maintain current power relations. On the other hand, by giving speakers of different languages access to new opportunities and resources, the development of global
languages can potentially undermine current power relations. The growth of international languages can, however, also have unfavorable effects on speakers of minority languages, such as language loss and cultural assimilation. Thus, globalization may eventually result in the loss of distinctive
cultural knowledge and practices as well as the loss of linguistic variety. This article focuses on how language dissemination affects power relations and how urgent it is to take action to protect linguistic variety and promote multilingualism.
Determination of geochemical baseline and pollution of soil heavy metals in Suzhou, China
Authors: Su Haimin , Gao Yang , Xu Dongsheng , Sun Peng
Published: April 2023

To investigate the enrichment of soil heavy metals, 50 soil samples were collected and the vanadium (V), chromium (Cr), zinc (Zn), lead (Pb), copper (Cu) and arsenic (As) contents were measured by using an X-ray fluorescence spectrometer. The environmental geochemical baseline values of heavy metals were determined by using standardised methods, and the pollution and enrichment degrees of heavy metals were evaluated based on the geoaccumulation index method and enrichment factor method. The results show that the vanadium, chromium, copper, zinc, lead and arsenic contents vary widely, with mean values of 81.32, 65.54, 17.16, 49.28, 20.04 and 11.68 mg/kg, respectively. Except for arsenic, the average values of the other five elements are lower than the soil background values of Anhui Province. The results of the standard reference method indicate that the six heavy metal elements have a strong correlation with iron (Fe), and the baseline values of heavy metals are 81.33, 65.56, 17.18, 49.29, 20.04 and 11.67 mg/kg, respectively. The mean values of Igeofor the six heavy metals are less than 0, indicating that there is no pollution of heavy metals in the soil of Suzhou. The average enrichment factor is greater than 1, with slight enrichment, and the interference of human activities on soil heavy metals is not obvious.

The structure of insufficiently deformed areas at the non-steady phase of extrusion was studied. The tests at Kamensk Uralsky Metallurgical Works using a 120 MN press and 800 mm dia. container, in order to extrude a 355.6 mm dia. Bar was performed. The bar material is the Al–Mg–Si AD33 aluminum alloy (GOST 4784), similar to ASTM 6061. The percentage reduction was 80 %, and the reduction ratio was 5.06. After that, the macrostructure, microstructure, and average grain size along the radius, mechanical properties at room and elevated temperatures were investigated. It was found that the extruded bar macrostructure is fine-grained, homogeneous, and dense, with no nonmetallic or intermetallic inclusions. The cross-section contained several structures. The central part is weakly deformed preserving the dendritic cell structure inherited from the casting. At the circumference, a streaked structure is formed. Its components are crushed and uniformly distributed. We measured the strength at elevated temperatures and compared the results to the data available in the literature. The tested material strength almost doubled, thus indicating its incomplete softening. The ductility was also performed. The DEFORM-2D software, in order to simulate the low reduction of extrusion was used. The metal at the circumference is exposed to a greater strain from the extrusion beginning. A step-by-step analysis indicated that at the first step, the strain is localized near the die hole. In the second step, a rigid area is formed in the vicinity of the die/container liner interface. The circumference layer of metal with a 1.75–2.00 reduction of area is formed. At the bar center, this range is 0.75–1.00 (half of the circumference value). In the third step, the circumference layer with an elevated strain has a wedge-like shape. In the fourth step, the circumference layer (with elevated strain) has an equal thickness along the extrusion axis. This indicates the steady phase. The plastic strain at the bar front end is higher at the circumference than in the center. This confirms the structural analysis results. They show that the central part of the bar may retain its cast structure, while the circumference is deformed. If the bar central part is required to have some specific properties, the bar has to undergo another manufacturing operation to increase the accumulated strain. Re-extrusion processes the areas insufficiently deformed during the first extrusion.

Площадь, население, характеристики границ и ключевые объекты для четырех уровней микрорайонов — лицевых кварталов, жилых микрорайонов, административных микрорайонов и общин — определены на основе обзора литературы теорий планирования, рекомендаций и исследований о микрорайонах.
Оценка стоимости времени: применение в городской транспортной политике
Authors: Сергиенко Мария
Published: April 2023

Оценка стоимости времени определяет максимальную цену, которую индивид готов заплатить за получение дополнительной единицы свободного времени при прочих равных. В развитых зарубежных странах такое стоимостное выражение ценности времени в пути активно применяется для экономической оценки эффектов от проектов и инвестиций в транспортную инфраструктуру. В России, однако, использование оценки стоимости времени пока не внедрено в практику. В этой статье это впервые делается на российских данных: проводится оценка стоимости времени для регулярных рабочих поездок по Москве. Опираясь на эмпирические находки зарубежных исследований, автор выделяет факторы, потенциально влияющие на дифференциацию искомого показателя. Помимо времени и стоимости поездки такими факторами являются индивидуальный доход, преодолеваемое расстояние и используемый тип транспорта (личный или общественный). Используется метод заявленных предпочтений, реализуемый в рамках анкетирования, и порядковая логистическая регрессия. Показывается, что максимальная величина, которую готов заплатить среднестатистический работающий в Москве россиянин за одну минуту сэкономленного в поездке времени, при прочих равных составляет 8,25 рубля. Час сэкономленного времени, соответственно, оценивается в 495 рублей. Автор считает необходимым продолжать исследования в данном направлении, совершенствовать методологию поиска показателя и проводить регулярные национальные исследования стоимости времени населения. Это внесет весомый вклад в изучение транспортного поведения населения и сможет повысить эффективность транспортной системы страны в целом.

Is It Possible to Compete With Car Use? How Buses Can Facilitate Sustainable Transport
Authors: Liu Qihao , Liu Yuzheng , Chen Chia-Lin , Papa Enrica , Ling Yantao , Cao Mengqiu
Published: April 2023

The need to prioritise the development of bus transport has attracted widespread attention in the literature. This study aims to investigate how buses can be used to facilitate a sustainable transport system, using Heze, in China, as a case study. Our results show that older people, unemployed residents, and those whose points of departure or arrival are within the city centre are more likely to travel by bus. In addition, compared to other travel modes, travel by bus tends to become more popular as travel time and distance increase. We predict the probabilities of people using buses for journeys of different travel times and over varying distances and rank them in order. The results suggest that bus travel could potentially replace car travel when the travel time is between 15 and 30 minutes or the travel distance is more than 9 km. In terms of policy implications, governments and planners should pay more attention to creating additional bus lanes, extending the bus network and its infrastructure, optimising bus-related facilities and services, particularly for older adults, and increasing the punctuality and reliability of bus travel.

Family Management Ability and Transition Readiness in Young Adult Survivors of Pediatric Brain Tumors
Authors:   , Anil Ashley Elizabeth , Daly Brian P.
Published: April 2023

The transition into adulthood is a particularly vulnerable time for young adult survivors of pediatric brain tumors (YAS) and their caregivers due to challenges related to the late effects of their tumor and treatment. Caregivers may question their condition management ability (CMA) as their caregiving role extends into adulthood at a time when resources available for children are no longer accessible to the YAS. Social determinants of health (SDH) may also influence caregivers' CMA as they assist their YAS transition to adult care (transition readiness) by impacting the quality of caregiver's management and hence their confidence in managing. The aim of this study was to determine the relationship between CMA and transition readiness, and the moderating role of SDH for YAS with condition-focused mothers. We hypothesized that CMA and transition readiness would be positively related, and that as the risk of SDH factors increased the relationship between CMA and transition readiness would strengthen. A sample of 53 self-identified maternal caregivers of YAS reporting condition-focused scores (< 51) on the Family Management Measure CMA subscale, completed the Transition Readiness Assessment Questionnaire for their YAS, a cognitive late effect severity rating for their YAS, and a demographics questionnaire. The Social Vulnerability Index (SVI), calculated using 16 factors across US Census data, was utilized as a cumulative measure of SDH. T-tests, ANOVA, Pearson correlations, and multivariate linear regressions were used. The cumulative measure of SDH (SVI) was not related to CMA. Caregivers who reported protective SDH factors including living with a partner, support in caregiving, an annual household income of $60,000 or greater, and YAS with private insurance reported better transition readiness. When controlling for cognitive late effects rating, CMA was not related to transition readiness, and there were no interaction effects. Exploratory analyses found that cognitive late effects had a significant indirect effect on transition readiness through CMA, but only for families with lower SVI scores. Cognitive late effects demonstrated a significant total effect on transition readiness, but mediation by CMA and moderation by SDH factors were not supported. Caregivers with caregiving support, caregivers living with a partner, and YAS with private insurance reported significantly better transition readiness. Findings support the importance of targeted cognitive remediation. Cancer survivorship care models and healthcare policy that targets increased accessibility to and long-term engagement in existing survivorship care and enhancement of supportive services for YAS and caregivers that minimize financial toxicity are indicated.
School Administrators' Lived Experiences with the Special Education Process
Authors:   , Bastek-Jones Kelly Blanche , Smith Budhai Stephanie
Published: April 2023

School administrators are required to serve on Individualized Education Program (IEP) teams, yet many do not have the special education content knowledge and training to successfully participate in the special education process. With the accountability measures enacted by the Every Student Succeeds Act, a school administrator's performance is dependent upon the academic success of all students within their building, including students with disabilities. Throughout the special education process, particularly during an IEP meeting, school administrators must be able to ensure that students are receiving appropriate services in the least restrictive environment to foster academic success. The purpose of this phenomenological study is to explore the lived experiences of public school administrators without formal training in special education to understand their capacity to fully participate as an IEP team member. The study seeks to understand public school administrators', without formal training in special education, capacity to participate in the special education process. The study will specifically focus on school administrators' participation in evaluation meetings, reevaluation meetings, and annual IEP meetings. The study will also highlight the participants' perceptions of the preparation they received through their administrator preparation programs and professional development within their own districts that assisted in their ability to meaningfully participate in the special education process and how this participation encouraged or furthered steps towards community engagement. The following research questions guided this study: 1. How do public school administrators without formal training in special education describe how prepared they feel to meaningfully participate in the special education process? 2. How do public school administrators without formal training in special education describe their capacity to contribute to the determination of the least restrictive environment for students with disabilities during the IEP process? 3. How do public school administrators without formal training in special education engage families of students with disabilities within the school community? This study has the potential to provide information that may strengthen the capacity of IEP team members without formal special education training to serve all students with disabilities with fidelity, provide school leaders critical information that can assist them in avoiding being sanctioned and required to undergo due process, and highlight the connection between a school administrator involved in the special education process and community engagement.

This study is concerned with the development of a computational fluid dynamic (CFD) model for the OSU (Ohio State University) Rate of Heat Release Apparatus. The standard OSU reactor is about 1.4 m long with a rectangular structure and a conical exhaust region (chimney) for flow development and burning of the specimen induced by radiant heating and pilot flames. The chimney at the top of the reactor includes cooling flow channels along the chimney wall. A comprehensive computational fluid dynamic model for the OSU reactor (that considers the geometric details of the reactor) is now under development using ANSYS FLUENT. The validated model will serve as a benchmark for providing uniformity in predictions of the OSU reactors located in different laboratories. A validated model will also provide better understanding of the flow and heat transfer characteristics in the OSU reactor. The OSU calorimeter and the cone calorimeter are test devices that measure the rate of heat release from burning materials. While comparisons between data generated from the two instruments is found in the literature, no systematic attempt has been made to show conformity, of results between the two test methods. In addition, the OSU calorimeter is in frequent use by a government transportation agency for measuring the rate of heat release of materials used in the interior of passenger aircraft. There are maximum allowable values of peak heat release rate of such materials and accurate measurement of these rates is imperative.

Servant Leadership has not been examined broadly amongst specific racial backgrounds or how implementation of the philosophy may contribute to positively increasing Black employees' psychological safety and voice outcomes. Gaps exist and researchers have called for additional research and examination of servant leadership and its relationship to new constructs; through this examination of servant leadership, the intent is to sufficiently contribute to those gaps in research. To that end, this study will focus on servant leadership, and a construct to add to the depth of the theory. In so doing, it is important to understand the connotation of "servant" as not a subservient ideal to the precursor of leadership, but rather, the ideal of selfless service. Finally, this study aims to highlight a systemic evaluation of servant leadership mediated by psychological safety, and moderated by race, and gain a broader understanding of how the construct increase individual Black employees' voice.
Desenvolvimento e difusão da tecnologia de fabricação de estruturas em guias de ondas em alumínio
Authors: Neto Alfrêdo Gomes
Published: April 2023

As estruturas em guias de ondas geralmente são fabricadas em ligas metálicas, inox ou alumínio. Na banda X (8GHz-12GHz), os guias de ondas e antenas tipo corneta são, na maior parte dos casos, importados, o que inviabiliza a sua utilização nos laboratórios didáticos de microondas, tanto pelo custo como pelo processo de importação. Nos últimos anos, a tecnologia de fabricação de estruturas em guia de ondas em alumínio vem sendo desenvolvida no GTEMA/CEFET-PB. Além da utilização de perfis em alumínio com outras aplicações comerciais, facilmente adquiridos em empresas locais, um considerável avanço é a substituição das soldas, geralmente tipo TIG, pela utilização de adesivo epóxi. Esta tecnologia permite a fabricação de estruturas em alumínio com uma boa qualidade, assim como o reparo de estruturas danificadas, com um custo de aproximadamente 15% das estruturas equivalentes importadas. Neste artigo são apresentados guias de ondas e antenas tipo corneta, sendo avaliadas as dificuldades encontradas e os resultados comparados com os das estruturas importadas. É proposta a fabricação de outras estruturas, tais como linhas fendidas, filtros, atenuadores, etc. Dessa forma, espera-se contribuir para a difusão dessa tecnologia e o estabelecimento de parcerias entre instituições.

A prática educativa acontece quando é permeada por uma ação dialógica, por um processo de interação educador-educando, por metodologias participativas. O processo de ensino-aprendizagem deve ser visto, assim, pelo viés da horizontalidade, pela via de mão dupla, onde ora se ensina e ora se aprende. O objetivo deste artigo é discutir a categoria “diálogo”, buscando uma correlação com a prática pedagógica, tanto na Educação Básica como no Ensino Superior. Os construtos teóricos respaldam-se nos autores: Paulo Freire (1983, 1987, 1996), Melo Neto (2004, 2006) e Scocuglia (2001 2006). A partir da revisão bibliográfica apresentada, resgatamos o conceito “diálogo”, na visão desses autores. Na primeira parte do trabalho, definimos a etimologia do conceito “diálogo”. Na segunda parte, ressaltamos o conceito no olhar dos autores analisados. Na terceira parte, apresentamos nossas considerações, enfatizando a importância do diálogo na afirmação do sujeito comunicativo, e o meio de formação perfeito para a inclusão do homem no meio social. Finalizando, destacamos que toda prática educativa, quando baseada na ação transformadora do diálogo, constitui-se como a verdadeira forma de respeitar o educando. Os resultados apontam para a necessidade de que, juntos, discentes e docentes construam novos conhecimentos e promovam a inclusão social.
A atividade de caixas bancários: sofrimento psíquico e prazer no trabalho
Authors: Souza Luciane Albuquerque Sá de , Neves Mary Yale Rodrigues
Published: April 2023

Neste artigo apresentamos uma análise sobre a relação trabalho e saúde mental dos caixas bancários de agências da Caixa Econômica Federal na cidade de João Pessoa - PB. Procuramos apreender as estratégias de regulação da sua atividade de trabalho, suas vivências de sofrimento psíquico e prazer relacionadas à atividade executada e as estratégias de defesa elaboradas para enfrentar o sofrimento e/ou processos de adoecimento. Optamos pelo uso de instrumentos como entrevistas individuais semi-estruturadas e observação da atividade inspirada à luz da Análise Ergonômica da Atividade, buscando uma leitura detalhada da atividade de trabalho realizada pelos participantes da investigação. Os dados produzidos foram interpretados através da técnica de análise de conteúdo temática, onde identificamos alguns aspectos acerca de como os caixas têm vivenciado suas experiências laborais frente a condições e organização do trabalho tão deletérias. Verificamos os movimentos realizados pelos mesmos ao criarem estratégias defensivas que os auxiliam no enfrentamento do sofrimento e na busca pela transformação deste em prazer. Neste sentido, constatamos que, apesar dos caixas bancários vivenciarem uma relação nem sempre salutar com seus clientes, paradoxalmente, é este convívio que se traduz como sua principal fonte de prazer e que dá sentido ao trabalho efetivamente realizado.

Different process of separation was used in the chemical industry, in particular, extraction is a process used to increase the quality of resins in oil removing impurities like organics solids and heavy metals. Supercritical carbon dioxide offers high selectivity at the end of the extraction process of light hydrocarbons from heavy oils mixture. A simulation technique in Aspen Plus ®software was used to develop the process and sensitivity analysis of the extraction configuration. The simulation of extraction process includes two output streams: the first one, a top stream (unpaved oil), and the second one a bottom stream (asphalt residue). A steady state methodology was implemented for process simulation. The sensitivity analysis was used to assess the influence of variables such as solvent flow rate, temperature and pressure. It was found a significant increase in the flow rate of unpaved oil when the solvent flow rate is increased. Optimal extraction values were selected depending on temperature and pressure effects over the process. An increase in temperature directly enhances the quality of API gravity. In certain occasions, an increase in pressure affects the light oils extraction because of product drag.
The Construction of the Thetic Acts by Czesław Znamierowski
Authors: Kupis Patryk
Published: April 2023

Czesław Znamierowski created the concept of thetic acts, which by European standards at the time, was an original theoretical model in legal theory. He based it on the observations that there are suchlike human actions that do not cause effects of physical consequence of the same action e.g. such as making a promise, making a will, a sale or other legal acts. This article compares this concept with a concept based on similar observations i.e. the concept of conventional actions created by Zygmunt Ziembiński and his team. The connection between these concepts is not obvious, even though both were created by the Poznan Centre of Legal Theory. This article will explore the question whether the concept of conventional actions is a development of the concept of thetic acts, or whether it is purely a concept based on similar assumptions that genetically constituting a separate theoretical model.
