Authors: Mendes Wendes Dias , Pinheiro Maria Laura da Silva , Romano Fábio , Borghi Ângela , Mestriner Marcelo Antônio
Published: March 2022

OBJETIVO: O objetivo do presente estudo foi relatar o sucesso do tratamento de uma má oclusão esquelética de Classe III, com ênfase na biomecânica utilizando técnicas
ortodônticas tradicionais. CASO CLÍNICO: A paciente apresentava perfil côncavo, sobressaliência negativa, desvio funcional da mandíbula, sorriso invertido e apinhamento anterossuperior, com protrusão do lábio inferior, com ângulo ANB de -3° e Wits de -4 mm, que comprovavam a má oclusão esquelética de Classe III. As opções de tratamento foram tratamento ortodôntico-cirúrgico, camuflagem ortodôntica
com extrações de pré-molares ou camuflagem ortodôntica sem extrações. Como não havia queixa da estética facial, optou-se pela terceira opção. Braquetes Edgewise foram
utilizados, com torque vestibular de coroa nos incisivos superiores e torque resistente nos incisivos inferiores. Elásticos intermaxilares assimétricos de Classe III foram também utilizados para corrigir a relação molar, potencializar as inclinações dentárias e promover a rotação da mandíbula no sentido horário. RESULTADOS: Ao fim do tratamento, foi obtida correta oclusão, estética facial e sorriso agradável. CONCLUSÕES: A correção da má oclusão esquelética de Classe III com mecânica convencional mostrou-se viável, levando em consideração o padrão de crescimento da
paciente, aspecto facial, domínio da biomecânica e comprometimento da paciente com o tratamento.

Authors: Melo Triana Jhom Alexander , Herrera Correa Camilo Andrés
Published: March 2022

Esta investigación surge de la necesidad de generar una propuesta dirigida a la infancia, basada en las experiencias de los niños, en aras de crear relaciones más armoniosas entre ellos y su entorno. De lo anterior surgió la pregunta de investigación: ¿cómo la construcción de una experiencia dirigida a educación ambiental de niños y niñas de 4 a 6 años que viven en el municipio el Rosal, Cundinamarca, contribuye a generar una relación más armoniosa entre ellos y su entorno? Todo esto, enmarcado en un paradigma cualitativo con un diseño hermenéutico. Metodológicamente establecimos tres momentos: una fase preparatoria, una fase analítica y una fase informativa, concluyendo, a partir de los hallazgos, que el estudio puede ser un punto de partida para conocer de manera integral cómo se dan los procesos de desarrollo, enseñanza, participación y experiencias significativas, dentro de una categoría tan difícil de definir como la infancia.
Comparison of endoscopic and open methods of surgical treatment for lumbosacral spinal canal stenosis: a systematic literature review
Authors: Gizatullin Sh. Kh. , Kristosturov A. S. , Davydov D. V. , Stanishevsky A. V. , Povetkin A. A.
Published: March 2022

Objective. To analyze clinical outcomes and complication rates of transforaminal and interlaminar endoscopic decompression and open microsurgical operations performed for lumbosacral spinal canal stenosis.

Material and Methods. The data of 60 literature sources selected in accordance with the inclusion and exclusion criteria in the PubMed, Science Direct, Google Scholar and Cochrane Library databases were systematized by evaluating diagnostic methods, clinical pictures and surgical treatment of the lumbar spinal canal stenosis. Original studies, case series and reviews containing information on surgical methods for the treatment of spinal stenosis at the lumbar level were analyzed.

Results. The complication rate after transforaminal endoscopic decompression (relapses, infectious complications, damage to the dural membrane and spinal roots) does not exceed 2.7 %, which is significantly lower than that in open microsurgical operation (4.8–8.8 %). Endoscopic decompression and reconstruction of the spinal canal demonstrate good clinical outcomes, lower number of bed-days, readmissions, and good economic benefits. When stenosis is combined with instability of the spinal motion segment, performing only a decompressive operation in any volume does not give a significant clinical result, and stabilization surgery is required.

Conclusion. The introduction of endoscopic reconstructive surgery for spinal canal stenosis in the lumbosacral spine is associated not only with technical progress and improvement of endoscopic optics, but also with the search for the causes of unsatisfactory results of open operations. Endoscopic interventions showed good clinical outcomes and a decrease in the complication rate. However, the evidence base needs to be expanded due to the lack of randomized trials to compare open decompression and stabilization, and endoscopic reconstructive surgeries in patients with various manifestations of spinal stenosis.
Enchondromatosis with cervical spine involvement in children: small series and review
Authors: Malamashin D. B. , Mushkin A. Yu. , Glukhov D. A. , Snishchuk V. P.
Published: March 2022

Objective: to present different variants of the clinical course and surgical treatment of an extremely rare vertebral pathology – enchondromatosis with involvement of the cervical vertebrae in children. Two cases of local and multiple forms of bone dyschondroplasia with damage to the cervical vertebrae, accompanied by orthopedic and neurological complications in children aged 7 and 11, are described. As a result of the operation, complaints were completely stopped in one child and neurological disorders were eliminated in another. The diagnosis was verified histologically. The results were followed up for more than 2 years and 1 year after the operation, respectively. Present-day data on Ollie’s disease in children are presented. Indications, timing and volume of surgical intervention for bone dyschondroplasia are determined individually, depending on the size, location, and number of enchondromas. However, if the cervical spine involvement is complicated by increasing pain and neurological disorders, it is precisely decompression of the spinal cord that should be set as a priority aim of the surgery.

Authors: Peleganchuk A. V. , Turgunov E. N. , Mushkachev E. A. , Sanginov A. J. , Simonovich A. E. , Pavlov V. V.
Published: March 2022

Objective. To analyze the influence of sagittal balance parameters on the risk of dislocations of the head of the femoral component of the hip joint endoprosthesis.

Material and Methods. A retrospective analysis of medical records of 113 patients with idiopathic coxarthrosis who underwent unilateral total hip arthroplasty was performed. The study assessed the parameters characterizing the sagittal balance in patients without prosthetic femoral head dislocation in the postoperative period (Group 1; n = 60) and in patients treated for prosthetic femoral head dislocation (Group 2; n = 53). Comparison of indicators was carried out by non-parametric Mann – Whitney U-test, and identification of dislocation predictors – by building single- and multi-factor logistic regression models. Differences were considered statistically significant at the achieved significance level p < 0.05.

Results. In Group 1, the type 3 sagittal balance according to Roussouly prevailed (48 %), in Group 2 – types 1, 2 and 4 (75 %). In patients with types 1 and 2 sagittal balance, the dislocations of the prosthetic femoral head occured 1.84 times more often than in patients with type 3, and that in patients with type 4 – 1.66 times more often.

Conclusion. Patients with Roussouly type 3 sagittal balance  have significantly lower risks of postoperative dislocation of the prosthetic femoral head, as compared with those with types 1, 2 and 4.
A Comparative Analysis of Search for and Look for in Four Corpora
Authors: Kang Namkil
Published: March 2022

The main goal of this paper is to compare search for and look for in the TV Corpus (TVC), the Movie Corpus (MC), the Corpus of Contemporary American English (COCA), and the British National Corpus (BNC). When it comes to the TV Corpus, it is interesting to point out that look for was preferable to search for in the TV programs of America, the UK, Canada, Australia, New Zealand, and Ireland. A further point to note is that the frequency of search for (1,898 tokens) and look for (5,423 tokens) reached a peak in the 2010s. With respect to the Movie Corpus, it is interesting to note that look for was favored over search for in the movies of six countries. More interestingly, search for (515 tokens) and look for (2,259 tokens) reached a peak in the 2010s. The COCA clearly shows that search for truth (369 tokens) and look for ways (566 tokens) are the most preferred by Americans. It is significant to note, on the other hand, that 36.36% of forty four nouns are the collocations of both search for and look for in the COCA. Similarly, the BNC shows that search for evidence (19 tokens) is the most commonly used one in the UK, whereas look for work (34 tokens) is the most widely used one. Finally, it is noteworthy that 17.64% of fifty one nouns are the collocations of both search for and look for in the BNC.

Subjektivierung der Arbeit in a Nutshell
Authors: Schreyer Jasmin , Pfeiffer Sabine , Sauer Stefan , Nicklich Manuel , Blank Marco , Tihlarik Amelie
Published: March 2022

Im sozialwissenschaftlichen Diskurs und den medialen Debatten wird die Covid-19-Pandemie zunehmend als disruptive Kraft in Bezug auf die Digitalisierung der Arbeitswelt wahrgenommen. Während dabei vor allem die Möglichkeit von Homeoffice thematisiert wird, steht im Zentrum unseres Artikels die situative Be-Arbeitung dieses Wandels durch die Beschäftigten im Zuge betrieblicher Reorganisation – mit seinen sichtbaren mittel- und ggf. langfristigen Folgen für die zukünftige Gestaltung von Arbeit. Der Beitrag zeichnet diese Zusammenhänge anhand eines qualitativen Panels nach: Seit dem ersten Lockdown wurden wiederholt Interviews mit Führungskräften unterschiedlicher Branchen geführt, um ihre laufend reflektierten Perspektiven zu erheben. Dabei zeigt sich: Einerseits greift Subjektivierung als struktureller Prozess des instrumentellen Zugriffs der Organisation auf Subjektpotenziale und damit auf den ganzen Menschen ins Leere. Andererseits ermöglicht die Subjektivierung von Arbeit als spontaner und selbstorganisierter Prozess erst die erfolgreiche Be-Arbeitung der Herausforderungen durch die Pandemie. Sichtbar wird in der Pandemie eine Art ‚Kontingenzkompetenz‘ der Beschäftigten, die im Nachgang von den Unternehmen wieder integriert und zur Erwartung im Sinne einer strukturellen Subjektivierung werden könnte.
Die Gegenwart der Krise als Erosion unternehmerischer Zukünfte
Authors: Schürmann Lena , Stamm Isabell , Scheidgen Katharina
Published: March 2022

Der Beitrag untersucht aus Perspektive der subjektorientierten Arbeitsforschung, wie Soloselbstständige die frühe Corona-Pandemie deuten und der Krise begegnen. Dafür wurden im Sommer und Herbst 2020 insgesamt 40 Interviews mit Soloselbstständigen aus drei Erwerbszweigen (Handwerk, Kultur, Coaching) geführt. Herausgearbeitet wird, wie Soloselbstständige branchenübergreifend eine starke Abhängigkeit vom Markt erleben und erfahren, dass ihre Planungen und Zukunftsentwürfe in Frage gestellt werden. Obschon alle Befragten auf ähnliche Weise den Anforderungen zur Umgestaltung ihrer Soloselbstständigkeit begegnen, treten branchenbezogene Ungleichheiten in den Möglichkeiten der sinngestützten Krisenbewältigung hervor. Damit bereichert der Beitrag die sich gegenwärtig konstituierende Debatte um die Ungleichheitswirkungen der Corona-Pandemie aus qualitativ-sinnrekonstruktiver Perspektive.
„Helden“ oder Arbeiter*innen?
Authors: Hürtgen Stefanie
Published: March 2022

Der Beitrag diskutiert alltagspolitische Intervention von Arbeiter*innen zu ihrer „Systemrelevanz“ demokratietheoretisch. Die These lautet, dass objektiv und subjektiv ein fundamentaler, in der Wissenschaft viel zu wenig beachteter Zusammenhang von sozialer Demokratie und gesellschaftlichem Charakter von (Lohn-)Arbeit besteht. Der Beitrag beginnt mit einer illustrativen Darstellung alltagspolitischer Interventionen zu Systemrelevanz, diskutiert anschließend den Zusammenhang von Arbeitsbegriff und Demokratie und aktualisiert diesen Zugang mit Bezug auf die ökofeministische Debatte und einen Begriff von Arbeit als fürsorglicher Praxis. Abschließend wird die diskurspolitische Umwandlung von Arbeiter*innen in „Helden“ als Angriff auf soziale Demokratie skizziert.
Getting attention in different languages: A usage-based approach to parenthetical look in Chinese, Dutch, English, and Italian
Authors: Van Olmen Daniël , Tantucci Vittorio
Published: March 2022

The present article examines the broad function of attention-getting embodied by parentheticallookin Chinese, Dutch, English and Italian. It analyzes a sample of the marker’s occurrences in corpora of spontaneous conversations and of interviews and discussions in terms of a systematic typology of parameters of interactional behavior and adopts a range of statistical methods to uncover patterns of (dis)similarity. The results include, inter alia, a cross-linguistic preference for clause-initial and turn-initial/medial position, a strong association across languages with assertive and expressive speech acts and an attraction to the onset of quotations. Variation in and exceptions to these tendencies are observed too. The findings are explained with reference to phenomena such as persistence and entrenchment and contribute to a better understanding not only of attention-getting in different languages but also of intersubjectivity, constructed dialogue, and illocutional concurrences.
The case of question-based exclamatives: From pragmatic rhetorical function to semantic meaning
Authors: Bardenstein Ruti
Published: March 2022

In this paper, I analyze the cyclic linguistic evolution of questions via Bardenstein’s ‘persistence principle’ (Bardenstein, Ruti. 2020b. Persistent argumentative discourse markers. The case of Hebrew rectification-marker be-ʕecem (‘actually’).Journal of Pragmatics172. 254–269) and argue that questions become “polysemous” via a core function. I show that it is the question’s initial rhetorically-recruited function that motivates its semantic change (alongside grammatical and prosodic changes) and it is that function that also persists throughout its history. I focus my analysis on question-based exclamatives whose peresistent function is the speaker’s strong stance and show that this function persists even when the question-based exclamative cyclically evolves into an adverbial NPI (Negative Polarity Item).
K-12 teachers’ perceptions of the effectiveness of online EFL teaching and learning during the COVID-19 pandemic
Authors: Zou Bin , Chen Xinyi , Sun Weifeng
Published: March 2022

During the Coronavirus disease outbreak, education in schools and universities was conducted through online platforms worldwide. School teachers in China have had a taste of online teaching, which never appeared to be a necessity before the COVID-19 pandemic in 2020. This research explores the effectiveness of English as a foreign language (EFL) teaching at the primary and secondary school levels during the COVID-19 pandemic in China. The research tools comprise questionnaires and semi-structured interviews. A total of 132 teachers from more than 10 provinces completed the online questionnaire, and 12 teachers were involved in semi-structured interviews. The results showed that while some EFL teachers adopted effective online pedagogies, others encountered challenges in online teaching. The teachers who had comprehensive Technological Pedagogical Content Knowledge (TPACK) or with previous online teaching experience tended to be more optimistic about teaching effectiveness in online language education. However, less training and a lack of TPACK and skills can hinder effective online teaching.
DO LINKS TO TAX HAVENS AFFECT COMPANIES’ FINANCIAL PERFORMANCE? THE CASE OF SLOVAKIA
Authors: Elexa Ľuboš , Ištok Michal , Šlampiaková Lea
Published: March 2022

This paper aims to quantify the impact of direct equity ownership links between Slovak companies and tax havens. We distinguish between three types of tax haven: onshore, midshore and offshore. The financial impacts are measured by indicators of profitability (ROA); activity (total asset turnover); liquidity (current ratio); and bankruptcy (IN05). To measure the impacts, we link the Bisnode and Finstat databases. The first database lists those Slovak companies that had links with tax havens during 2005–2015. The second provides financial statements for all Slovak companies. It was found that: 1) There are statistically significant differences in all investigated indicators between Slovak companies with and without links to tax havens. Those with links to tax havens generally reported worse economic situations and levels of performance compared to those without such links. We conclude that having a parent company resident in a tax haven had a negative effect on financial performance. 2) There are statistically significant differences between the selected indicators of company performance, across the different categories of tax haven, and for companies with no links to tax havens. 3) Those with no such links show statistically significant correlations between all their examined performance indicators. But for those companies with links to tax havens, the only statistically significant correlation was between profitability and the remaining indicators. 4) Companies with ownership links to tax havens are clearly engaged in profit-shifting activities. The results suggest opportunities for follow-up projects, especially focusing on different industries and company size that could specify their heterogeneous approaches and variability in objectives.
COVID-19, Poverty, and Inequality in Bangladesh
Authors: Lata Lutfun Nahar
Published: March 2022

The COVID-19 pandemic has shaken the global economy and the livelihoods of disadvantaged populations. Bangladesh, like other developing countries, has been hit hard, and marginalized groups have suffered the most. Before the pandemic, Bangladesh’s economy was growing rapidly, and the country was known for its steady improvement in health and education development indicators. Yet in its pandemic response, the government has been unable to provide adequate aid and health facilities for the large population living in poverty. The response has been hampered by lack of resources, corruption in the delivery of economic support, and existing health inequalities.

The study was aimed to discover the form of comics used in language learning and the development process, as well as the style of the Comic suitable with the interest of Japanese language students used in the previous study, which is expected to elaborate types of necessary research in the future for Japanese language teaching material development. There were 20 articles reviewed related to comics development for language learning. Based on the review result, it was found that 1) There are two types of comics, namely 1-Panel Comic used to explain one specific material and 4-Panel Comic used for conversation materials. However, there has yet any research related to comics development in the form of comic books; 2) In terms of process, both types of comics are formulated and developed by referring to a curriculum and learning plan so that the comics may assist students in understanding learning material; 3) Comic styles discussed in previous researches refer to American comic style, and thus less suitable to be used as Japanese language learning materials. The style used in Japanese comics is predicted to be more attractive for Japanese language students. However, there has yet any scientific study on the development of Japanese style comics in Japanese language learning.
Penggunaan Keigo dalam Bahasa Jepang untuk Bisnis

Published: March 2022

This study aims to describe politeness when performing speech acts in business using Leech's theory of politeness principles. The research object is the speech data of business people when interacting within one company or between companies. The research method used is descriptive qualitative research because it aims to describe linguistic phenomena naturally. Politeness is a rule of behavior determined and mutually agreed upon by a particular community, so politeness is also an agreed requirement in social behavior. In their interactions, business people must be polite. This is reflected in his speech with the perpetrator of the speech act. The study results indicate that in addition to being grammatically correct in terms of the form of Keigo itself, it must pay attention to language politeness. In general, using Keigo in business conversations in various social speech contexts emphasizes simplicity and respect. In addition, it also prioritizes wisdom and sympathy.

Campus Potrerillo: proposta di intervento architettonico a fini sociali
Authors: Formiggini Paola Giovanna , Paradiso Michele , Muñoz Robledo Jose Fernando
Published: March 2022

L’oggetto della ricerca che supporta questo articolo prende forma da un seminario tematico “Materiali e tecniche costruttive per il dialogo interculturale con i paesi del sud del mondo” del Professore Michele Paradiso. L’argomento principale è rappresentato dalle tecniche locali, come “guadua” e il sistema costruttivo del “bahareque”, utilizzato in Colombia. La ricerca è stata sviluppata in tre fasi: la prima parte presenta un’analisi storico-critica dell’area di intervento e del contesto, la seconda si è incentrata sui materiali mentre che la terza fa riferimento alla progettazione architettonica. Per quanto riguarda il progetto, la proposta consiste nella creazione di un campus socioculturale all’interno di un’area confiscata al narcotraffico colombiano, l’hacienda Potrerillo, situata all’interno della zona di espansione KM41 nel municipio di Manizales. L’area necessita di interventi architettonici, al fine di mettere in sicurezza le abitazioni e dare una nuova identità sociale. L’obiettivo, perciò, è stato quello di realizzare una struttura organica, ma allo stesso tempo resistente e in armonia con l’ambiente. In più, il progetto lascia un’impronta evidente, visto che lo scopo è di sensibilizzare cittadini locali e turisti alla conoscenza dell’area. In estrema sintesi, la proposta progettuale costituisce un complesso moderno e innovativo che, a prima vista, sembra discostarsi dal contesto per il suo aspetto formale, ma in realtà, resta legato al luogo attraverso l’utilizzo di guadua e bahareque nell’ambito costruttivo.
On the right to accommodation for Canadians with disabilities: space, access, and identity during the COVID-19 pandemic
Authors: Capurri Valentina
Published: March 2022

In this article, I explore the societal reluctance to accommodate and include persons with illnesses/disabilities, which has rendered them “second-class” citizens. This reluctance exists despite several pieces of legislation whose goal is to create an inclusive and accepting social as well as physical environment across Canada. In October 2020, the Ontario government introduced a mask mandate as a non-medical procedure to limit the spread of COVID-19. I argue that this mandate has further reduced civil society’s willingness to accommodate those who are unable to wear a mask due to their disability or medical condition, especially when their illness or disability is not visibly discernible. By making use of the concept of “state of exception” developed by Giorgio Agamben, and the biopower/biopolitics paradigm introduced by Michel Foucault, I attempt to examine what the mask mandate means for persons with disabilities as well as for society at large. My investigation is an effort to uncover why we are finding ourselves in a situation of inaccessibility and exclusion at this moment in time, despite the widespread rhetoric of unity and support for each other throughout the pandemic. Through a reading of Agamben, I aim to uncover why persons with disabilities have been, once again, considered justifiable collateral damage on the altar of necessity (in this case, the necessity to fight COVID- 19 at all costs).

Abordar la propuesta estética del poeta Germán Walter Choque Vilca (Jujuy, Argentina 1940-1987) nos habilita a problematizar la noción de “literatura andina” (Espino Relucé, 2019) en general y a su vez, atender a las particularidades locales que aún están pendientes de revisión. Por esto, en el presente trabajo nos proponemos sistematizar los componentes andinos presentes en la poética del escritor jujeño; y reflexionar acerca de la posibilidad de abordar “lo andino” a partir de una relocalización desde la región subandina del norte de Argentina.

BACKGROUND AND OBJECTIVES

Asthma is considered a precaution for use of quadrivalent live attenuated influenza vaccine (LAIV4) in persons aged ≥5 years because of concerns for wheezing events. We evaluated the safety of LAIV4 in children with asthma, comparing the proportion of children with asthma exacerbations after LAIV4 or quadrivalent inactivated influenza vaccine (IIV4).

METHODS

We enrolled 151 children with asthma, aged 5 to 17 years, during 2 influenza seasons. Participants were randomly assigned 1:1 to receive IIV4 or LAIV4 and monitored for asthma symptoms, exacerbations, changes in peak expiratory flow rate (PEFR), and changes in the asthma control test for 42 days after vaccination.

RESULTS

We included 142 participants in the per-protocol analysis. Within 42 days postvaccination, 18 of 142 (13%) experienced an asthma exacerbation: 8 of 74 (11%) in the LAIV4 group versus 10 of 68 (15%) in the IIV4 group (LAIV4-IIV4 = −0.0390 [90% confidence interval −0.1453 to 0.0674]), meeting the bounds for noninferiority. When adjusted for asthma severity, LAIV4 remained noninferior to IIV4. There were no significant differences in the frequency of asthma symptoms, change in PEFR, or childhood asthma control test/asthma control test scores in the 14 days postvaccination between LAIV4 and IIV4 recipients. Vaccine reactogenicity was similar between groups, although sore throat (P = .051) and myalgia (P <.001) were more common in the IIV4 group.

CONCLUSIONS

LAIV4 was not associated with increased frequency of asthma exacerbations, an increase in asthma-related symptoms, or a decrease in PEFR compared with IIV4 among children aged 5 to 17 years with asthma.

Force-displacement relationships for NiTi alloy helical springs by using ANSYS: Superelasticity and shape memory effect
Authors: El Mtili Chayma , Khamlichi Abdellatif , Hessissen Loubna , Waqas Badar Hafiz Muhammad
Published: March 2022

Shape memory alloys are smart materials which have remarkable properties that promoted their use in a large variety of innovative applications. In this work, the shape memory effect and superelastic behavior of nickel-titanium helical spring was studied based on the finite element method. The three-dimensional constitutive model proposed by Auricchio has been used through the built-in library of ANSYS® Workbench 2020 R2 to simulate the superelastic effect and one-way shape memory effect which are exhibited by nickel-titanium alloy. Considering the first effect, the associated force-displacement curves were calculated as function of displacement amplitude. The influence of changing isothermal body temperature on the loading-unloading hysteretic response was studied. Convergence of the numerical model was assessed by comparison with experimental data taken from the literature. For the second effect, force-displacement curves that are associated to a complete one-way thermomechanical cycle were evaluated for different configurations of helical springs.

In this study, a total of 135 Chinese mitten crab (Eriocheir sinensis) samples were collected from four major crab-producing provinces (Jiangsu, Hubei, Anhui, and Liaoning) in China. The content of 24 trace elements in the edible parts of mitten crabs was determined by inductively coupled plasma mass spectrometry (ICP-MS). In addition, the content of trace elements in crab samples collected from different provinces was compared, and the heavy metal levels exceeding the standard were evaluated. Twenty four trace metallic elements were determined in Chinese mitten crab samples. The single factor pollution index (Pi), percentage of provisionally tolerable weekly intake (PTWI), and target hazard quotients (THQ) were used to evaluate the pollution level and food safety of Chinese mitten crabs. The final assessment results of dietary risks led to the health risk assessment accompanying food safety recommendations on Chinese mitten crabs. The overall finding of this study established that Chinese mitten crab aquatic products can be eaten for nutrition; however, attention should be paid on the potential food safety risks of some heavy metals. Moreover, efforts on developing the industrial economy by the local government and peoples’ safety from food risks may also increase the awareness of environmental protection.

Surface Enhanced Raman Scattering (SERS) is a technique that is increasingly being used to detect trace amounts of various types of molecules, especially organic and biological molecules. The SERS effect is available mainly due to the SERS substrate - a noble metal surface that is rough at the nano level or a set of noble metal nanoparticles in a certain arrangement. Such a SERS substrate acts as an analyte Raman signal amplifier and can provide amplification up to millions of times and even more. The amplification coefficient of the SERS substrate is determined mainly by the number of ‘hot spots’ it contains as well as the ‘hotness’ of these spots. In turn, a ‘hot spot’ is a certain space around the tips or a nanogap between particles, where the local electromagnetic field is intensely enhanced, while the ‘hotness’ is determined by the sharpness of the tips (the sharper the hotter) and tightness of the gaps (the narrower the hotter). This report presents an overview of the research results of fabricating a type of SERS substrate with a high enhancement factor, which is the SERS substrate made from silver nanostructures coated on the silicon surface. With the aim of increasing the number of ‘hot spots’ and their quality, as well as ensuring uniformity and reproducibility of the SERS substrate, silver nanostructures have been fabricated in various forms, such as nanoparticles, nanodendrites and nanoflowers. In addition, the report also mentions the use of the above silver nanostructures as SERS substrates to detect trace amounts of some pesticides and other toxic agents such as paraquat, pyridaben, thiram, cyanide...

Published: March 2022

In this work, entropy scaling approaches for viscosity of pure Lennard-Jones (LJ) fluids and their mixtures have been investigated. To do so, we have employed reliable viscosity database available in literature for the pure LJ fluids, and performed the molecular dynamics simulation to generate viscosity database over a wide range of thermodynamic condition for the LJ mixture fluids. It has shown that for the pure LJ fluid, the entropy scaling approaches using the macroscopic properties for the reduction of viscosity yield noticeably better collapse of data than the one using the zero-density viscosity in the dense fluid region. In addition, we have developed viscosity correlations based on these approaches. It has been obtained that the correlations of macroscopic properties approaches predict the pure LJ fluid viscosity with average absolute deviation of around 4% more coming from the low-density states, whereas it is of around 8.50% more coming from the dense states for the other one. Finally, the viscosity correlations have been applied to the LJ mixtures. Interestingly, the correlations of macroscopic properties approaches are able to provide good estimations for all mixtures studied. However, it deteriorates for the viscosity of dense mixtures when the other employed.

Published: March 2022

In this paper, we study some higher-order nonclassical properties of the superposition of three-mode photon-added trio coherent state such as antibunching, squeezing, and entanglement. The results show that in the case with fixed the higher-order, when increasing the numbers of added photons, the manifestation of the higher-order three-mode sum squeezing is more obvious, but the degrees of higher-order antibunching, and higher-order three-mode entanglement are more reduced. Besides, with fixed the numbers of photon addition to the superposition of three-mode photon-added trio coherent state, the higher-order nonclassical properties as antibunching and entanglement are more pronounced, but three-mode sum squeezing is more decreased when increasing the number of the higher-order.
Electron Transport Through Experimentally Controllable Parabolic Bubbles on Graphene Nanoribbons
Authors: Nguyen Mai-Chung , Viet Nguyen Huy
Published: March 2022

We present a theoretical study of electron transport properties through experimentally controllable graphene nanobubbles [P. Jia et al., Nat. Commun. 10 (2019) 1] employing a tight-binding model and the non-equilibrium Green's function formalism. Sharp conductance peaks are observed at low energy region which signifies the emergence of quasi-bound states caused by pseudomagnetic field in the strained nanobubbles. Analysis based on local density of states reveals the nature of electron transmission at peak energies. Our results also show that the emergence of quasi-bound states and its role in electron transport depend on both strain strength and bubble size: when the strain or size of the bubble increases, more quasi-bound states emerge and resonant tunnelling assisted by these quasi-bound states becomes dominant.

Patients at high cardiovascular risk, older people with cardiovascular comorbidities, as well as those with hypertension and familial hypercholesterolemia are more susceptible to severe coronavirus disease 2019 (COVID-19). Such patients are likely to be at increased long-term atherothrombotic risk after COVID-19. The renin-angiotensinaldosterone system (RAAS) not only plays a key role in the development and progression of cardiovascular diseases, but is also responsible for the penetration of the Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV-2) into the cells of target organs and the development of infection. Given that RAAS inhibitors and statins increase the expression of angiotensin-converting enzyme type 2 receptors, concerns were initially raised about their possible adverse effect on COVID-19 course. However, at present, we have data from large-scale, including randomized clinical trials and meta-analyses, confirming the organ protective effects of RAAS inhibitors and statins by reducing the inflammation severity and fibrosis in tissues. The review attempted to assess the potential role of these drugs in the management of SARS-CoV-2-infected patients and their impact on the development of complications.

Studying the Wikipedia Math Essential Pages using Graph Theory Metrics
Authors: Mahmood Sajidah
Published: March 2022

Abstract COVID-19 pandemic enforced students in schools and universities all around the world to study using the online and blinded learning. In these learning models, students depend on the Internet for information searching of different scientific essentials to improve their skills and to overcome the gap of facing instructors. One of the most popular sources of information is Wikipedia. In this work, we attempt to study the relations of different math essential pages of Wikipedia to find the relation between these topics. A graph has been constructed for these pages. The graph theoretical metrics, such as, centrality, edge weights and clustering coefficient have been extracted of the constructed graph. The extracted values have been investigated to gain more insights of the math topics that should be studied first. The extracted results show that the in-degree property of the articles and the betweenness value of these articles are correlated. Moreover, there is no relation between the in /out-degree of the pages. Finally, the constructed graph has a small average shortest path and a high global cluster coefficient. This proves that the constructed graph follows the small world phenomenon. Keywords: Graph metrics, Math essentials, Gephi, Small world phenomenon, Directed graph

Abstract We described the early development of Myloplus asterias and M. lobatus, two fish species of the Serrasalmidae using morphological, meristic, and morphometric characteristics. These herbivores serrasalmids are heavily fished because of their commercial importance in the Amazon. The individuals were collected between 2016 and 2020 in the limnetic zone of open water and macrophyte stands in the Lower Amazon River floodplain. We tested different growth models to identify the development pattern of these species. During the initial ontogeny, these two species can be differentiated mainly by the myomeres total number, 37 to 39 in M. asterias vs. 40 to 41 in M. lobatus, the pigmentation pattern, and dorsal-fin ray numbers. These characteristics are effective in distinguishing these species from other serrasalmids. The morphometric relationships were also different between these two species, showing distinct patterns in growth between the analyzed features. An identification key for larvae of some sympatric Serrasalmidae species from the Amazon basin is presented. Our expectation is that this study will contribute to the knowledge of the initial ontogeny and the biology of fish species in the Neotropical region.
