Published: July 2022

BACKGROUND

Health is considered one of the most relevant issues of the human being. If we focus on the quality of health of teachers, this is a delicate and worrying issue since the health indices in this group show that they are worse than in other work environments.

OBJECTIVE

The main objective is to evaluate the effects that the COVID-19 pandemic has had on the health of the teaching staff at all educational levels (except university level) in the Autonomous Community of Aragon (Spain).

METHODS

The methodology is based on a descriptive cross-sectional research design with a sample of 920 teachers. Main Outcome Measures. Two validated questionnaires were applied for the Spanish population, a teacher health questionnaire and the Goldberg GHQ-12 questionnaire. Likewise, sociodemographic and occupational data were included.

RESULTS

The prevalence of psychological stress according to the GHQ-12 scale has averaged 59.7%, with women being the most affected in this sense (62.8% women versus 50.4% men). Women also suffered greater exhaustion and greater physical complaints (muscular, cognitive and voice). Teaching staff at High Schools showed lower satisfaction, lower self-efficacy and greater voice disorders.

CONCLUSIONS

The COVID-19 pandemic has left health problems for teachers, especially women. The results of psychological stress in our research are much superior to other studies prior to it, being necessary a specific treatment and work in the classrooms for both students and teachers to reduce the risk of suffering from depression or anxiety.

Published: July 2022

BACKGROUND

Opioid medications are important in pain management. Despite this, many patients progress to unsafe medication use. With few personalized and accessible behavioral treatment options to reduce opioid-related harm, new and innovative approaches are urgently needed to fill this gap. Co-design methods offers an opportunity to put patient partners at the centre of the solution.

OBJECTIVE

This study involved the first phase of co-design of a digital brief intervention (BI) to reduce opioid-related harm – investigating the lived experience of chronic non-cancer pain (CNCP) in treatment-seeking patients with a particular focus on opioid therapy experiences.

METHODS

Eligible patients were aged 18-70 years, with CNCP at clinically significant intensity (> 4/10). Purposive sampling was used to engage patients on public hospital wait lists via mail, or the treating medical specialist. Participants (N = 18; 10 women; Mage = 49.5+/- SD years) completed semi-structured phone interviews. Interviews were transcribed verbatim, thematically analysed using grounded theory and member checked by patients.

RESULTS

Eight overarching themes were found (mostleast prominent): Limited treatment collaboration and partnership; Limited biopsychosocial understanding of pain; Continued opioid use when benefits don’t outweigh harms; Trial and error approach to opioid use; Cycles of hopefulness and hopelessness; Diagnostic uncertainty; Significant negative impacts tied to loss; and Complexity of pain and opioid journeys.

CONCLUSIONS

This study advances progress in co-design of digital BIs by actively engaging patient partners in their lived experiences. Key recommendations for consideration in the co-design process should guide personalized solutions to address the complex care needs of patients with CNCP.

Актуальність. Сколіотична деформація хребта була і є об’єктом численних розробок та досліджень різних фахівців медицини. Ведення пацієнтів активно включає в свою програму такий потужний фактор, як функціональне лікування, і для пацієнтів після операції, і для хворих, яким хірургічне втручання показане. Мета. Поліпшення результатів фізіофункціонального лікування пацієнтів зі сколіотичною хворобою шляхом експериментально-клінічного обґрунтування ефективності різних фізичних вправ, що застосовуються при лікуванні хворих. Матеріали та методи. Розроблені математичні моделі хребта із C-подібною та S-подібною сколіотичними деформаціями, які використовували для аналізу напружено-деформуючого стану. Були перевірені 17 різних вправ, серед яких 12 асиметричних, 3 — симетричні та 2 — деротаційні. Із них: 6 вправ ми використовуємо при шийно-грудному типі; 8 — при грудному; 8 — при грудопоперековому; 12 — при поперековому та 10 вправ — при S-подібному типі деформації хребетного стовпа. Результати. Створення математичної моделі дозволило вивчити напруження, що виникають при деформаціях хребта за різних варіантів навантаження. Ми отримали чіткі уявлення про розподіл внутрішнього напруження в хребетних рухових сегментах. Було встановлено, що більшість вправ нашого комплексу сприяє створенню компресійних зусиль на опуклій стороні деформованого хребта та формуванню дистракційних зусиль на боці увігнутості. Аналогічні дані підтверджують показники антропометричних досліджень. Все вищесказане свідчить про доцільність враховувати локалізацію вершини викривлення хребетного стовпа при розробці комплексів функціонального лікування. Безперечно, жодне експериментальне дослідження не відбиває увесь спектр анатомо-фізіологічних процесів живого організму. Однак створення математичної моделі дозволило розробити положення диференційованого застосування кінезитерапії в конкретній клінічній ситуації, а результати розробок стали частиною клініко-біомеханічного обґрунтування функціонального лікування сколіотичної патології. Висновки. Дослідження за допомогою математичної моделі дозволило вивчити диференційовану дію методів кінезитерапії на деформацію хребта залежно від її вершини. Дане дослідження дозволило біомеханічно обґрунтувати показання та протипоказання для використання різних фізичних вправ при лікуванні сколіотичної хвороби. Проведене дослідження дало змогу удосконалити методологічний підхід до розробки комплексів лікувальної гімнастики з урахуванням топічних особливостей деформації хребта.

У період з 2018 по 2021 рік на лікуванні знаходилось 114 хворих з діагнозом: остеоартрит колінного суглоба 1–3-ї ст. за Kellgren-Lawrence. Діагноз верифікували рентгенологічно, деталізували за даними магнітно-резонансної томографії, інтраопераційно артроскопічно. Пацієнтів було проліковано відповідно до розробленого алгоритму з використанням малоінвазивних регенеративних методик: збагачена тромбоцитами плазма, концентрат червоного кісткового мозку (BMAC) та гіалуронова кислота. Контрольна група не передбачалась через низку етичних та технічних причин. Виходячи з твердження, що остеоартрит— це прогресуюче захворювання, стійкі позитивні зміни в суб’єктивній оцінці колінного суглоба та відсутність ознак прогресування при використанні інструментальних методів обстеження можна вважати за успіх даної методики. Оцінка результатів лікування проводилась через 1, 3, 6, 9 та 12 місяців за допомогою міжнародних опитувальних шкал Knee and Osteoarthritis Outcome Score, Western Ontario McMaster Universities OA Index, International Knee Documentation Committee, даних повторних магнітно-резонансних досліджень та безпосереднього макроскопічного дослідження при повторних артроскопіях. Відповідно до міжнародних суб’єктивних шкал оцінки функції та болю суглоба у пацієнтів після лікування з використанням ін’єкційних регенеративних засобів виявили стійке покращення в терміні спостереження до 12 місяців. Спираючись на ці клінічні результати, можна дійти висновку, що розроблена схема лікування — це сучасна регенеративна терапія, яка допомагає відновити ушкоджені ділянки опорно-рухової системи завдяки впливу збалансованого комплексу мезенхімальних стовбурових клітин, факторів росту, цитокінів. Вироблений алгоритм виготовлення та застосування BMAC є безпечним та раціональним.
Тваринні моделі іммобілізаційних контрактур. Огляд методів та тенденцій
Authors: Fishchenko V.O. , Khasawneh Ayham
Published: July 2022

Контрактури — це хронічна втрата рухливості суглобів, викликана структурними змінами в кісткових тканинах, включаючи м’язи, зв’язки та сухожилля. Вони розвиваються, коли ці зазвичай еластичні тканини заміщуються нееластичними тканинами. Найчастішою причиною контрактур є іммобілізація. Контрактура є складною клінічною проблемою, оскільки характер травми часто не корелює зі ступенем функціонального порушення, що ускладнює прогнозування ризику розвитку патології. Вивчення причинних факторів контрактури на пацієнтах не може бути поширеною клінічною практикою з певних причин, пов’язаних як з етичною стороною проблеми, так і з відсутністю часового фактора спостереження. Моделі на тваринах дозволяють вивчати патогенез захворювання та оцінювати стратегії лікування. Тим не менш, не було розроблено жодної тваринної моделі для оцінки ліктьового суглоба, що необхідно для повного вивчення та розуміння клінічних проблем, характерних для цього складного суглоба. У роботі наведені основні методи моделювання іммобілізаційних контрактур на тваринах. Існує 2 основні підходи до моделювання контрактур суглобів — травматичний та нетравматичний. Травматичні, тобто хірургічні методи фіксації за допомогою спиць, крючків, пластинок тощо, дають надійну фіксацію, але часто супроводжуються ускладненнями у вигляді набряків, запалення, інфікування зони втручання, а також заважають чистоті експерименту, коли необхідно виключити ушкодження тканин навколо суглоба. Нетравматичнї методи моделювання контрактур, тобто за допомогою виключно зовнішніх засобів фіксації, виключають деякі негативні впливи хірургічних методів, але супроводжуються недостатньою надійністю впродовж тривалого часу. Також зовнішня фіксація може викликати набряки, подразнення шкіри, інші негативні прояви. Обидва методи моделювання конт-рактур потребують постійного контролю в процесі проведення експерименту для нівелювання можливих ускладнень та запобігання їм.

This study aimed to examine the perceived risks and benefits of Genetically Modified Organisms (GMO) in Nigeria with a focus on the agricultural technology of nitrogen use efficient, water use efficient, and salt-tolerant (NEWEST) Rice. A descriptive survey method was adopted for this study. Using a convenient sampling technique, 100 residents were drawn from the general population as respondents for this study. The questionnaire which was the instrument for data collection was administered to the respondents by the researcher personally. The results show that 58% of respondents will buy or eat NEWEST Rice. About 20% of the respondents would buy or eat NEWEST Rice because of its cheaper price, 15% for its nutritional benefits, and 13% for its better look and taste. Findings from this research also revealed that the perceived risks of NEWEST Rice are cross-pollination, adverse effects to human health, not looking and tasting good like organic rice, and antibiotic resistance in humans. The benefits identified include an abundance of rice supply to reduce poverty and starvation in Nigeria, improve the efficiency, profitability, and productivity of farmers, NEWEST Rice can minimize the use of water and fertilizer, better nutritional qualities, and reduction in pesticide use. This study, therefore, shows that NEWEST Rice will be averagely accepted (58%) in Nigeria. However, due to the intense debate on GM crops, there is a need for an improvement in the efficacy of scientific communication. There is also a need to create an informed, balanced public perception on the important issue of genetic engineering used in agriculture, even from the confined field trials, multi-location trials and use of GM crops in Nigeria.

La caña guadúa es un material noble, poco explotado, sostenible y económico, que posee grandes capacidades físicas y mecánicas, por lo que es muy común que se utilice como material de construcción, sin embargo, las estructuras de este material poseen una desventaja frente a cargas horizontales, generándose desplazamientos excesivos. Por tal razón, en esta investigación se revisó el comportamiento de este tipo de estructuras cuando se juntan con el ladrillo artesanal. Para ello, se construyeron cuatro estructuras hexagonales con caña guadúa (Angustifolia Kunth), reforzadas con mamposterías de ladrillo artesanal; para las uniones, se utilizó la conexión Simón Vélez con una pequeña modificación en la forma del gancho. Las cuatro estructuras se sometieron a carga lateral cíclica para obtener las curvas de histéresis, las cuales permitieron determinar la ductilidad, rigidez secante y variación de amortiguamiento viscoso de las estructuras. Adicionalmente, se realizó una comparación con una investigación similar que omite el refuerzo con ladrillo, y se concluyó que incluir mampostería de ladrillo artesanal entre la estructura de caña guadúa, aumenta significativamente la resistencia y rigidez de la estructura, logrando una disminución significativa en las derivas.

Published: July 2022

The growth of RDF (Resource Description Framework) datasets and the expansion of their use in conjunction with the definition of SPARQL, a declarative query language, have made RDF data management an active area of research and development. In this regard,mechanisms have been proposed to help users find their desired answers in less time, including ranking methods and preference-based queries. Skyline queries constitute one of the most practical and predominant types of preference-based queries. The aim ofthis work was to provide a guide to specifying SPARQL skyline queries using syntax proposed in state-of-the-art works, and SPARQL versions 1.0 and 1.1. The results show the possibility of rewriting skyline queries in SPARQL to express preferences. We planto develop a tool to translate SPARQL skyline queries applying the different grammars proposed, into SPARQL 1.0 and 1.1 with the aim of providing an automatic mechanism of translation.
Diagrid Mono Column Structures with Different Geometry in Plan: A Review
Authors: Johnson Sijin , Raj Indu Susan
Published: July 2022

Abstract: Due to increasing urbanization and rapid infrastructural development, scarcity of land is a problem. Multi-story structures have been constructed to eliminate this problem. But for the requirement of large service spaces and good aesthetic appearances, the mono column structural system achieved popularity. Mono column structures are complicated since the mono column supports the whole structure and all other member acts as cantilevers. Mono column structures are vulnerable to seismic loads and adding a diagrid structural system on the periphery of the building improves seismic performances. This review paper aims to review the previous studies on mono column structure and diagrid structural system. It also focuses to review the performance of different plan geometry buildings.
Battery Share: A New Revolution of Sharing Your Smartphone Battery Power
Authors: Nagar Pulkit
Published: July 2022

Abstract: The majority of individuals in the globe nowadays struggle with their mobile phone's batteries dying while they are out and about. The concept to create a system that allows consumers to transfer battery life from one phone to another was born to address this problem. In a cell phone battery, an electric charge is chemically stored. Batteries for mobile phones have a static charge that is stored. This concept is centred on the usage of a technology, which transforms static electric charge into data packets and transmits them from source to destination (i.e., from one mobile to another mobile) via a wireless network (much like sharing using file sharing applications utilising Wi-Fi) using a technology called Wi-Fi Direct. To connect with another device, it makes use of the Wi-Fi card in the smartphone. It establishes a secure link between the two devices so that data may be sent at fast rates without interruption and is converted back to static energy to extend battery life. This is not the one same as the existing wireless charging technology in which phone has to be kept on a charging pad and it starts charging. Instead, here in this proposed technology the electric charge will be converted in form of data packets and transfer them over a wireless communication channel like, Wi-Fi.

A Proportional Investigation among UPFC and DPFC in a Grid Associated Photovoltaic Organization
Authors: Teja P. Rajendra Bhanu
Published: July 2022

Abstract: In this paper a proportional investigation between Unified Power Flow Controller (UPFC) and Distributed Power Flow Controller (DPFC) in a grid incorporated photovoltaic system is performed. A grid connected solar generation scheme with boost converter and voltage source inverter (VSI) is taken as the key model. Due to power quality issues like power oscillations, harmonic distortions, voltage sags and swells, the grid side system has to be absolutely monitored and restricted. One way to mitigate these power quality troubles is by using reactive elements like shunt/series reactor and shunt/series capacitor. The drawback on using these reactive elements is sub synchronous resonance phenomenon. Gratitude to FACTS equipment, which emerged out as power conditioning units and helps to feed power with required standards and free from power quality issues. Among them, the contemporary FACTS devices are Controller Distributed Power Flow (DPFC) and Unified Power Flow Controller (UPFC). Though the aims of both the devices are same but their working principles are different. In this paper the effect of adding a DPFC and UPFC to a solar PV generation system is analysed. A detailed working principle and operation of both the devices were presented. At last, MATLAB/SIMULINK environment is used to evaluate the performances of abovementioned devices.

Появление новых высокопрочных высокотемпературных термопластов открывает перспективы для разработки новых видов полимер­полимерных пар трения. Однако вследствие низкой теплопроводности сопрягаемых термопластичных полимеров фрикционное тепло локализуется в области трибоконтакта. Это оказывает значительное влияние на физико­механические свойства полимеров и их сопротивление изнашиванию. С учетом результатов экспериментальных исследований реализована модель процесса трения и изнашивания применительно к созданию полимер­полимерной пары трения ПЭЭК—СВМПЭ. Для обеспечения отвода тепла предложено использовать полимерные композиты, в которых за счет введения теплопроводящих включений повышается теплопроводность, снижается степень деградации прочностных свойств, вызванных фрикционным нагревом, снижается интенсивность изнашивания. Показано, что значительное повышение теплопроводности обеспечивается за счет создания теплопроводящей сетки из нановключений. Проведена верификация модели по данным трибологических испытаний образцов, изготовленных методом 3D­печати.

Published: July 2022

Представлена математическая модель диагностирования технологических дефектов (микропор) в полимерном материале с использованием встроенного оптоволоконного датчика с протяженной малоотражательной брэгговской решеткой. Диагностика основана на результатах измерения на выходе из оптоволокна информативного спектра отражения брэгговской решетки. Разработан алгоритм обработки деформационного спектра для случаев, когда чувствительный участок оптоволокна расположен в полимерном материале в деформационной “зоне возмущений” дефекта в виде сферической полости; диагностируемые параметры — размер и расположение дефекта относительно известной длины и расположения чувствительного участка. Представлены результаты математического моделирования световых и деформационных спектров вдоль чувствительного участка оптоволокна при разных диагностируемых расстояниях от оптоволокна до центра сферической полости в полимерном материале. Непосредственное численное решение (деконволюция) интегрального уравнения Фредгольма здесь не рассматривали, спектры отражения получены как конволюции с соответствующими известными спектрами деформаций для чувствительного участка оптоволокна; спектры деформаций найдены с использованием решения задачи теории упругости для области “среда с дефектом/оптоволокно”.
Theoretical discussion and standard reconstruction of substantive consolidation in bankruptcy reorganization
Authors:   Wonkwang University Legal Research Institute has, WANG Xiao
Published: July 2022

To achieve Pareto optimality and substantive fairness, the practice of substantive consolidation in bankruptcy reorganization in China is needed. However, after analyzing the legal documents and judicial cases in the past three years, it can be seen that there are problems in the application, such as cognitive dislocation and theoretical conflicts. Moreover, there are deficiencies in the standard for judging whether the proceeding is applicable or not, such as vague meaning and unclear relationship, and there is a relative lack of systematic thinking. Therefore, on the one hand, a clear conceptual distinction should be made between the substantive consolidation from the perspective of bankruptcy law and the corporate merger in the field of company law. Besides, the contradictions between substantive consolidation and the traditional theoretical principles like bankruptcy petition doctrine, creditor’s reliance interests, and corporate personality independence should be resolved through methods which contain interest measurement and perspective shifting. On the other hand, it is necessary to construct a standard system with objective mode and subjective mode for determining whether the proceeding should be applied, so as to respond to different judicial needs. Furthermore, the objective mode should be detailed and strict, and it can be refined into three parts: formal requirement, necessity requirement and feasibility requirement. The subjective mode is based on the unanimous and real volition of the relevant stakeholders, which fully respects the freedom of the parties to dispose of their rights.

Aim: The present study was carried out to ascertain the prevalence and species-spectrum of Dactylogyrus in Indian major carp farms of Odisha state, India. Further it is to establish host preference of Dactylogyrus catlaius among Indian major carps.. Methodology: The study was conducted from September 2018 to March 2020 in thirteen districts of Odisha. During that period, total 786 fish samples comprising of Labeo rohita, Catla catla and Cirrhinus mrigala were examined using Level II diagnosis. A total of 25 Dactylogyrus positive samples identified using microscopy representing all the districts have been amplified using 28S rDNA PCR and sequencing. Secondary structures for 28S rDNA fragments were predicted using MFold package (version 3.5) software. To ascertain host preference of D. catlaius a standard co-habitational challenge method was followed in which infected fishes were kept together with healthy fishes (all three Indian major carps). Results: Total 786 fish samples comprising of Labeo rohita, Catla catla and Cirrhinus mrigala, all three Indian major carps were examined and overall prevalence of 64.50% for Dactylogyrus spp. was found. Further, winter season was the most favoured season whereas L. rohita was the most preferred host for this parasite. A total of 25 Dactylogyrus isolates, i.e., 22 Dactylogyrus catlaius, two D. vastator and one D. scorpius were identified using 28S rDNA PCR and sequencing. Hence, D. catlaius has been identified as the most prevalent Dactylogyrus species in Odisha. Secondary structures for 28S rDNA fragments of three Dactylogyrus spp. were also predicted reflecting their diversity. Further in a cohabitational challenge study, D. catlaius was found to be a generalist parasite infecting all three Indian major carps with a higher preference for rohu L. rohita. Interpretation: The present study provides a holistic information regarding Dactylogyrus prevalence in the state of Odisha. Further, the study illustrates host-parasite relation of D. catlaius among Indian major carps which would strengthen knowledge on developing any prophylactic measure in future.

Aim: The present study was conducted to find out the dynamics of insect pests in Indian bean, Lablab purpureus during different season at Lower Pulney hills in Tamil Nadu and to predict the occurrence of insects/pests for management practices. Methodology: Field trial was conducted in the rain fed Hill Avarai, Lablab purpureus (Linn.) at Thandikudi village of Lower Pulney hills to study the population dynamics and weather factors interaction with sucking pests, leaf, flower eating insects and pod borers. Forecast modeling of major pests of hill avarai were done with ARIMAX analysis. Results: Around 21 insect species belonging to four major insect orders viz., Hemiptera, Lepidoptera, Coleoptera, Orthoptera with division of three categories namely sucking insects, leaf, flower eating insects and pod borers. Among them the occurrence of sucking pests was maximum and damage followed by leaf, flower eating insects and pod borers. All sucking pests, leaf, flower-eating insects and pod borers showed positive correlation with maximum and minimum temperature, while relative humidity, rain fall and wind speed had negative correlation with sucking pests, however, positive correlation was observed with leaf, flower-eating insects and pod borers. Interpretation: Under temperate conditions biotic factors such as maximum and minimum temperatures have an important impact in Indian bean pest population fluctuation. ARIMAX model created in this work could be used to forecast the appearance of significant major pests of bean such as A. craccivora, L. trifolii, and M. vitrata in the subtropical areas of Tamil Nadu, India.
ANÁLISE ACÚSTICA DE /l/ PRÉ E PÓS-VOCÁLICO DO PORTUGUÊS BRASILEIRO: DESCRIÇÃO COM BASE NA INFLUÊNCIA DO POLONÊS COMO LÍNGUA DE IMIGRAÇÃO
Authors: Rosinski Aline , Ferreira-Gonçalves Giovana
Published: July 2022

Este artigo apresenta uma análise de /l/ do português brasileiro, produzida em uma comunidade influenciada pelo polonês como língua de imigração. O segmento no polonês caracteriza-se como menos velarizado (GUSSMANN, 2007) em início e final de sílaba. Assim, analisou-se se, no português de contato com o polonês, a consoante apresenta as mesmas características, em ambas as posições silábicas. Para a investigação, analisaram-se acusticamente produções de /l/ pré-vocálico de falantes de português e polonês como língua de imigração, habitantes da comunidade investigada. Para a análise, foram medidos os valores de F2, F1 e da sua diferença, para determinar o nível de velarização dos segmentos, seguindo Brod (2014) e Recasens (2004). Para comparação com os dados analisados neste estudo, foram retomadas as produções de /l/ pós-vocálico apresentadas em Rosinski (2019). A análise revelou que, tanto em posição pré-vocálica como pós-vocálica, o segmento caracteriza-se como menos velarizado, ainda que, em início de sílaba, os níveis de velarização tenham sido menores. Tem-se, portanto, uma caracterização específica da produção do segmento para a comunidade de fala investigada, cujas práticas sociais – como orações e cantigas recitadas e conversas informais –, realizadas especialmente em seus núcleos familiares, promovem o contato linguístico e tornam peculiar o português local.
CAN MOBILITY AFFECT GRAMMAR AT THE MORPHOSYNTACTIC LEVEL? A STUDY IN BRAZILIAN PORTUGUESE
Authors: Siqueira Manoel , Freitag Raquel Meister Ko.
Published: July 2022

In this paper, a study about the presence of the definite article before possessed NP (D-presence) in Brazilian Portuguese is carried out with a sample constituted by sociolinguistic interviews with students from the Federal University of Sergipe (UFS), Brazil, to observe whether the distribution pattern of the variable suggests an effect of mobility in the students’ speech. An analysis is carried out with a sample from the Deslocamentos 2020 dataset, composed of sociolinguistic interviews with college students from Universidade Federal de Sergipe (UFS), balanced for degree of mobility (students from Sergipe, Alagoas, and Bahia), time in the undergraduate program, and sex (n = 60). Results show that D-presence is sensitive to dialectal factor, with D-absence predominating in data from Sergipe and Alagoas, and D-presence predominating in data from Bahia, but it is not sensitive to the integration into the new community considering speakers’ time in the undergraduate program. This result contributes to revealing how mobility affects grammar at the morphosyntactic level.
PRÁTICAS LINGUÍSTICAS, SIGNIFICADOS SOCIAIS E EXPRESSÃO DE IDENTIDADES: O CASO DE (-STE)
Authors: Do Amaral Kamilla Oliveira
Published: July 2022

Com base em uma articulação teórica entre Sociolinguística Variacionista, Antropologia Linguística e Sociologia (LABOV, 2008 [1972]; ECKERT, 2005, 2012, 2016, 2018, 2019; SILVERSTEIN, 2003; KIESLING, 2013; BOURDIEU, 1983), o objetivo deste artigo é refletir sobre os significados sociais das práticas linguísticas dos sujeitos e em que medida tais significados podem expressar suas identidades, atitudes e ideologias. Para subsidiar esta reflexão, analisamos o item (-STE) usado na comunidade de práticas virtual (CPV) Tal Qual Dublagens. Exploramos o uso desse item a partir de como os membros e não membros dessa CPV o avaliam Considerando o diálogo entre os dados e a articulação teórica, chegamos ao entendimento de que os significados sociais potencialmente indexicalizados por (-STE) são múltiplos e dinâmicos e constituídos por diferentes camadas, que podem se articular e se organizar de forma dialética: (i) uma relacionada a macrocategorias; (ii) outra a relação de grupo, seja de grupo regional, seja de grupo social; e (iii) outra a comportamentos e escolhas individuais. Essas camadas estão intimamente correlacionadas com uma noção de identidade que é plural e múltipla, sendo esta também constituída por camadas que se articulam dialeticamente e que estão assentadas em um contexto sociocultural e ideológico mais amplo.
Fractional operators with Kaniadakis logarithm kernels
Authors: Perovano Ana Paula , Silva Fernando Santos
Published: July 2022

In this article, more general types of fractional operators with κ-deformed logarithm kernels are proposed. We analyse the new operators and prove various facts about them, including a semi group property. Results of existence are established in appropriate functional spaces. We prove that these results are valid at once for several standard fractional operators such as the Riemann-Liouville and Caputo operators, the Hadamard operators depending on the of the scaling function. We also show that our technique can beuseful to solve a wide range of Volterra integral equations. Finally, the solutions of theκ-fractional differential equations can be deduced from the solution representation of theCaputo or Riemann-Liouville versions via scaling.
Processos de pensamentos ativados na resolução de tarefas matemáticas Standards e Não Standards
Authors: Das Flôres Aparecido Alves , Gusmão Tânia Cristina Rocha Silva
Published: July 2022

Para o estudo que trazemos à baila, levantamos a seguinte questão de pesquisa: que processos de pensamento são ativados por estudantes enquanto realizam tarefas matemáticas standards e não standards? Para respondermos a essa questão, analisamos as respostas de estudantes do ensino médio a dois testes, constituídos por tarefas standards e não standards. A pesquisa reúne dados de estudantes do curso Técnico em Edificações, oferecido no Centro Territorial de Educação Profissional (CETEP), localizado no interior da Bahia, Brasil. Dentro de uma abordagem qualitativa, do tipo descritiva, analisamos os dados à luz de referenciais cognitivos e metacognitivos sobre a conduta de estudantes ao resolverem problemas de matemática. Organizamos os protocolos de respostas aos testes em categorias de processos de pensamento ativados, a saber: pobre, rico, muito rico, confuso e em branco. Ao concluir a nossa análise, notamos que a maior parte dos estudantes manifesta processos de pensamento pobre para ambos os tipos de tarefas, utilizando pouco de estratégias cognitivas e também metacognitivas. Deduzimos daí que estudantes estão mais acostumados com a resolução de tarefas standards que de tarefas não standards, já que apresentaram certa rigidez no pensamento durante a resolução de questões que fugiam à rotina escolar.
The impact of the insurance market on economic growth: Evidence from developing countries
Authors: Baruti Blerta Haliti
Published: July 2022

The purpose of this study is to understand the development and role of the insurance industry in the development of the economic and financial systems in developing countries with a special emphasis on Kosovo. It is the continuation of the preliminary works where for the empirical analysis, secondary data from the relevant institution and the survey were conducted. The survey was conducted with financial managers from all insurance companies in Kosovo. The analysis shows that the insurance industry has an important role in the development of financial markets and therefore has a positive impact on the development of countries. Also, the analysis of the case of the Balkan countries shows that the factors related to the macroeconomic and financial sectors are important drivers for the future development of the insurance industry. It is worth asking: What role does insurance play in economic development? Where, according to the studies by Arena (2008) and Haiss and Sümegi (2008), and also from this research there is ample evidence that insurance contributes significantly to economic development by improving the investment climate and promoting a range of activities. The analysis in Kosovo shows that the insurance market gross written premiums have a positive linkage with the GDP growth of Kosovo. Even though the impact is small, it can increase with the potential growth of the insurance sector in Kosovo.
Rational mutagenesis of Thermobifida fusca cutinase to modulate the enzymatic degradation of polyethylene terephthalate
Authors: Mrigwani Arpita , Pitaliya Madhav , Kaur Harman , Thakur Bhishem , Guptasarma Purnananda
Published: July 2022

Thermobifida fusca cutinase ( TfC ) is a
carboxylesterase (CE) that degrades the environmental pollutant,
polyethylene terephthalate (PET). TfC also acts upon PET’s
degradation intermediates (DIs), such as oligoethylene terephthalate
(OET), and bis-/mono-hydroxyethyl terephthalate (BHET/MHET), to convert
these into terephthalic acid (TPA), the terminal product of PET
degradation. We examined TfC’s surface, compared it to that of
other CEs, and performed molecular docking and MD simulations with an
OET, 2HE-(MHET) , to understand interactions between
TfC’s surface and the OET, at TfC’s active site as well as
vicinal regions. We mutated 17 residues on TfC’s surface, mostly
individually, but sometimes using pairs of mutations, to see how these
modulate TfC’s activity. Most mutants/variants showed a decrease
in activity against solid PET. Some killed activity completely. However,
three mutations (L90F, F209I and F249R), made using a background
mutation (G62A) already reported to improve activity by almost
~2.0-fold, yielded increases in activity that were
between ~1.3- and ~2.0-fold higher than
that of G62A TfC (which we found to display a
~1.7-fold increase in activity over TfC, in our
own experiments). TfC variants, G62A/F249R, and G62A/F209I,
exhibit the highest activities yet observed in any TfC
mutants/variants, against PET, and BHET, respectively.
A single serine in the CC3 region of STIM1 is critical for STIM1-Orai1 binding and CRAC channel activation
Authors: Yu Tao , Li Xi , Liu Huajing , Jin Jing , Luo Qianqian , Li Shengjie , He Jun
Published: July 2022

Background and purpose: Store-operated Ca2+ entry (SOCE) is important
for the function of many cell types. It is controlled by the interaction
between ER Ca2+ sensor STIM1 and the plasma membrane Ca2+ channel Orai1.
CAD of STIM1 is required for SOCE. It contains two putative coiled-coil
regions (CC2 and CC3). The role of CC3 remains to be elucidated.
Experimental approach: various plasmids carrying different fluorescent
protein genes were constructed for better understanding the influence of
S417G mutation in CC3 on SOCE activation; Confocal imaging system,
calcium imaging technique and FRET technique were employed to examine
the actions of 2-APB on the interaction between STIM1 C terminus and
Orai1. Key results: Single-point mutation of the residue (S417G)
abolishes STIM1 C-terminus interactions with Orai1. Mutation of S417
also abolished CAD-Orai1 binding and Orai1 channel activation,
eliminated STIM1 puncta formation and co-localization with Orai1 and
SOCE. 2-APB were found to restore the binding of STIM1 C-terminus
mutant(S417G) to Orai1 and dose-dependently activated Orai1 channel.
Both CBD and NBD of Orai1 is required for 2-APB-induced coupling between
Orai1 and STIM1 C terminus mutant(S417G) and CRAC channel activation. We
also demonstrated 2-APB lead to delayed activation of Orai1-K85E
channel, although Orai1-K85E obviously impair 2-APB-induced STIM1
C-terminus mutant(S417G)-Orai1 coupling. Conclusions and implications:
Our data suggest that S417 in the CC3 domain of STIM1 is critical for
STIM1-Orai1 binding and CRAC channel activation. We also proposed
experimental models of combined STM1 or Orai1 mutants with 2-APB to
better understand the activation mechanism of CRAC.

Published: July 2022

In order to study the influence of welding flash on heat transfer performance of steel piston cooling gallery, the pistons with different structures are studied. In this paper, the finite element simulation calculation of the steel piston with the welding flash and the non-flash structure on the same model and the annular cavity section is carried out separately, and the amount of carbon deposited in the top of the steel piston and cooling gallery after 1000 hours test is measured. The comparative analysis finds that the existence of welding flash hinders the heat transfer of cooling gallery, resulting in an increase in the temperature of the inner surface of cooling gallery, which in turn increases the temperature of entire piston head. Carbon deposits in the top surface and cooling gallery of the steel piston, which affects the cooling effect.

Authors: Zhang Tianhua , Liu Chuanping , Wang Huigang , Guo Min , Zhang Mei
Published: July 2022

The radiative heat transfer in a high temperature granular bed of binary-size mixture was explored in this paper. The effective view factor between particles decreases exponentially with the increase in particle interval, increases with the increase in the size of the absorption particle but is hardly affected by the volume ratio of the mixture. The effective thermal conductivity of granular bed was further deduced basing on the characteristic of the effective view factor. It is indicated that the thermal conductivity is proportional to the particle size and temperature cubed, and increases with the increase in the particle size ratio and volume ratio. Finally, modified calculation correlations of the effective view factor and effective thermal conductivity were developed for binary-size bed based on the simulation results, and good accuracy of less than 0.01 and 10% had been achieved, respectively.
Stability and Regime Change: The Evolution of Accounting Standards
Authors: Chen Hui , Yang Li
Published: July 2022

We examine the evolution of accounting regulation by linking disclosure policies and investments in a dynamic voting model. The disclosure policies are the outcome of voting by entrepreneurs, whose preferences are influenced by their investments. The investments are in turn endogenously determined by current and future disclosure policies. Absent external influences, accounting regimes are stable. A disclosure regime of high (low) quality and a strong (weak) economy coexist and reinforce each other. However, regulatory interventions can result in regime changes by changing the entrepreneurs’ expectations, even without direct enforcement. Unexpected shocks could also result in regime changes by impacting economic conditions and hence voter composition. Our analysis provides a framework to study the interaction between accounting regulation and firms’ economic decisions.
