Published: December 2021

Brassica napus is the third most important oilseed crop in the world; however, in Korea, it is greatly affected by cold stress, limiting seed growth and production. Plants have developed specific stress responses that are generally divided into three categories: cold-stress signaling, transcriptional/post-transcriptional regulation, and stress-response mechanisms. Large numbers of functional and regulatory proteins are involved in these processes when triggered by cold stress. Here, our objective was to investigate the different genetic factors involved in the cold-stress responses of B. napus. Consequently, we treated the Korean B. napus cultivar Naehan at the 4-week stage in cold chambers under different conditions, and RNA and cDNA were obtained. An in silico analysis included 80 cold-responsive genes downloaded from the National Center for Biotechnology Information (NCBI) database. Expression levels were assessed by reverse transcription polymerase chain reaction, and 14 cold-triggered genes were identified under cold-stress conditions. The most significant genes encoded zinc-finger proteins (33.7%), followed by MYB transcription factors (7.5%). In the future, we will select genes appropriate for improving the cold tolerance of B. napus.

Published: December 2021

Genome-wide association studies (GWASs) facilitated the discovery of countless disease-associated variants. However, GWASs have mostly been conducted in European ancestry samples. Recent studies have reported that these European-based association results may reduce disease prediction accuracy when applied in non-Europeans. Therefore, previously reported variants should be validated in non-European populations to establish reliable scientific evidence for precision medicine. In this study, we validated known associations with type 2 diabetes (T2D) and related metabolic traits in 125,850 samples from a Korean population genotyped by the Korea Biobank Array (KBA). At the end of December 2020, there were 8,823 variants associated with glycemic traits, lipids, liver enzymes, and T2D in the GWAS catalog. Considering the availability of imputed datasets in the KBA genome data, publicly available East-Asian T2D summary statistics, and the linkage disequilibrium among the variants (r2 < 0.2), 2,900 independent variants were selected for further analysis. Among these, 1,837 variants (63.3%) were statistically significant (p < 0.05). Most of the non-replicated variants (n = 1,063) showed insufficient statistical power and decreased minor allele frequencies compared with the replicated variants. Moreover, known variants showed <10% genetic heritability. These results could provide valuable scientific evidence for future study designs, the current power of GWASs, and future applications in precision medicine in the Korean population.

Published: December 2021

With the increase in plastic waste, recycling becomes an urgent necessity to reduce and revalue it. PVC is one of the most widely used types of plastic in the world, and indeed it is among the most recycled. The effect of recycling on PVC or any other type of material is to reduce these characteristics, which also depends on the method by which it is recycled. Finding a way to increase the recyclability number of PVC by improving the mechanical characteristics will be an addition at the level of scientific research as well as at the industrial level. The addition of a bio-loading in the form of cow horns, coconut or chicken feathers on the flexible PVC with an experimental study of the results obtained allow to deduce the most adequate bio-loaded material to improve the mechanical characteristics after recycling. The experiments carried out on flexible PVC have shown the effects of bio-loading as well as the degradation brought by recycling on this type of plastic. The results obtained showed an improvement in the mechanical properties of rigid and flexible PVC with a natural bio-loading with the three fibers of coconut, cow horns and chicken feathers which enhance the environment, are very light and can be collected directly from the waste with a large amount.

Published: December 2021

Objectives: The aim of this systematic review was to identify factors influencing workers' intention to work while ill, using the Theory of Planned Behavior (TPB) as a theoretical framework. Methods: A systematic search of articles was carried out from PubMed, Scopus, and Web of Science databases. Eligibility of each article was assessed using PRISMA guidelines. Overall, 22 articles met the inclusion criteria after the selection process and were included in this review. Results: The factors fit into 3 constructs: (1) attitude (good and bad consequences of working while ill), (2) subjective norms (descriptive and injunctive norms on working while ill), and (3) perceived behavioral control (facilitators and barriers of working while ill). Conclusions: The TPB is a practical theory to conceptualize and understand the factors influencing workers' intention to work while ill. These findings provide initial knowledge on the development of a framework to measure workers' intention to work while ill and to propose appropriate interventions for workers with chronic illness.
Individual and Family Factors in Disordered Eating Patterns of Mexican-American Women
Authors: Marquez Becky , Benitez Tanya
Published: December 2021

Objective: In this study, we examined the contribution of individual- (acculturation, body mass index, and body size satisfaction) and family- (maternal weight-related messages and disordered eating patterns) level factors in predicting bulimic and dieting behaviors in young Mexican-American
women with overweight or obesity. Methods: We recruited adult Mexican- American mother-daughter dyads from the community. We conducted correlational analysis and hierarchical regression. Results: Daughters who were less satisfied with their body size reported higher symptoms of bulimic (r
= -.34, p < .01) or dieting behavior (r = -.36, p < .01). Daughters who received more positive maternal messages on eating and weight had mothers with lower symptoms of bulimic (r = -.43, p < .01) or dieting behavior (r = -.30, p < .05). Maternal symptoms of bulimic behavior were
the strongest predictor of daughters' bulimic behavior (ß = .379, p = .007), and body size satisfaction was the strongest predictor of daughters' dieting behavior (ß = -.372, p = .008) in adjusted models. Conclusion: Mexican-American women who are less satisfied with their body
size and have mothers with elevated symptoms of bulimic behavior are at risk for disordered eating patterns. Intervening at the individual level on body image and family level on maternal modeling of eating behavior may help support healthy weight management behaviors.

Published: December 2021

Control charts are effective tools for detecting out-of-control conditions of process parameters in manufacturing and service industries. The development of distribution-free control charts is important in statistical process control when the process quality variable follows an unknown or a non-normal distribution. This research thus proposes to use a distribution-free technology to establish a new control region based on the exponentially weighted moving average median statistic and exponentially weighted moving average interquartile range statistic for simultaneously monitoring the process location and dispersion and further sets up a corresponding new control chart. We compute the out-of-control average run length to evaluate out-of-control detection performance of the proposed control region and also compare the proposed control region with some existing location and dispersion control charts. Results show that our proposed chart always exhibits superior detection performance when the shifts in process location and/or dispersion are small or moderate. The new control region is thus recommended.

Keywords: control chart, distribution-free, dispersion and location, EWMA, kernel control region, kernel density estimation.
PREPARATION OF IRON- REDUCED GRAPHENE OXIDE/ EPOXY RESIN COMPOSITE AND ITS FLAME RETARDANCY AND THERMAL STABILITY

Published: December 2021

In order to reduce flammability, smoke release and enhance thermal stability of epoxy resin (EP), iron powder is mixed with graphene oxide/ epoxy resin (GO/EP) composite by mechanical blending. The combustion performance of composite material is investigated through limiting oxygen index (LOI), Underwriters Laboratory (UL)-94 test, and cone calorimeter test (CCT). Thermogravimetric-Fourier transform infrared spectroscopy (TG-FTIR) and scanning electron microscope (SEM) are also used to explore the mechanism of flame retardancy and smoke suppression. Results show that, with the addition of 0.5% mass fraction of GO and the corresponding iron powder combination (EP3 sample), the LOI value can achieve 32.5% while reaching the UL-94 V0 rating. Compare with EP0, the peaks of heat release rate, smoke production rate, and smoke factor values of EP3 are decreased by 42%, 60%, and 50%, respectively. The char and TG-FTIR data of EP3 reveal that it has a more compact structure, good thermal stability, and produce fewer toxic gases and smoke. Reduction of GO could inhibit the degradation of EP, and iron catalyzes the formation of carbonaceous char on the surface. Thus, the thermal stability and flame retardancy of EP are improved significantly. This study provides a suitable way to prepare graphene/EP composites that contain iron catalyst and can be extended to the industrial manufacture of flame retardant polymer composites.

There are two wind turbine topologies according to the axis of rotation: horizontal axis, "Horizontal Axis Wind Turbines" (HAWT) and vertical axis, "Vertical Axis Wind Turbines" (VAWT) [2]. HAWT turbines are used for high power generation as they have a higher energy conversion efficiency [2]. However, VAWTs are used in mini wind applications because they do not need to be oriented to the prevailing wind and have lower installation cost.

Owing to the long lifetime of Rydberg atom, easy to operate and easy to control the interaction between Rydberg atoms, Rydberg atom has attracted considerable attention in quantum information and quantum optics fields. Specially, the anti-blockade effect, as a physical resource, can be used to implement various tasks in quantum information processing. Based on the rigid dipole blockade, an ensemble of two-level Rydberg atoms trapped in three magneto-optical traps can be regarded as a superatom. Based on the superatom model, the in-phase and anti-phase dynamics of the three-body Rydberg superatoms are studied by adjusting the numbers of atoms, and the W state and two kinds of maximal entangled states are generated simultaneously. Our work has great potential applications in coherent manipulation and quantum information processing.The numerical simulations are performed based on the superatom model and thereby the formidable obstacle that the Hilbert space dimension grows exponentially with the particle number increasing can be completely removed. As a result, the quantum control and quantum entanglement can be achieved from the single-quanta level to the mesoscopic level.

Laser fusion research needs much more high-time-resolved diagnostic technologies to study the dynamic process in laser plasma. We develop a special method and setup a device to measure the electromagnetic field in the plasma by using a single electron bunch. The measurement covers the whole-time window of the plasma process driven by a 3.6 ns laser pulse. An electron source can generate a single electron bunch with 0–100 keV energy and 10ns bunch length. A laser pulse with 1 J energy and 532 nm wavelength irradiates on the edge of a silver target, the target nearby the irradiated spot is ionized into plasma. At the beginning of plasma generation, the head of the electron beam begins to pass through the plasma. Electromagnetic field in plasma pushes the electrons transversely. A high voltage pulse at a good time is used to deflect the electrons linearly in the transverse direction to avoid overlapping of the different electrons on the scintillator downstream. By analyzing the deflection distances of the different electrons in this single bunch, we succesfully achieve an average electronic field along the trajectory in the plasma in the whole plasma process. The maximum value of this electronic field is  \begin{document}$ 7.74\times {10}^{5}\;\mathrm{V}/\mathrm{m} $\end{document}     .
High-order Laguerre-Gaussian mode laser generated based on spherical aberration cavity

The high-order Laguerre-Gaussian (LG) mode output from an end-pumped Nd:YVO4 laser cavity with strong spherical aberration (SA) induced by short-focal-length lens is studied in this work. A long-focal-length lens L1 is used in the cavity to expand and collimate the beam, so that the beam incident on another short-focal-length lens L2 in the cavity undergoes a strong SA. Since the ring-shaped LG modes with different values of angular index m have different beam radii, the actual focal points of each order of beam are then spatially displaced. A flat output coupler (OC) is located near the focal point of L2, which is composed of a cat-eye retroreflector together with the lens. Such a retroreflector can provide only ideal retroreflection to the incident beam with a focal point exactly on the OC. Given the focal point displacements of the LG beams with different orders, such a mechanism can be used for implementing the transverse mode selection. The mode which has an actual focal point on the OC has a smaller loss than the other defocused modes. With an a-cut Nd:YVO4 as laser crystal, scalar (linear-polarized) single-mode LG output with radical index p = 0 and angular index m>0 is obtained. The laser mode-order is selectable from LG0, ±10 to LG0, ±33 under 878.6-nm incident diode pump power of 1.03 W, by simply adjusting the distance between the OC and L2 in a range of 0.5 mm, when using lens L1 with f = 150 mm and lens L2 of f = 33.9 mm. It is found that sufficient SA which makes the optical paths of the neighboring modes well distinguishable is essential for single-mode operation of a wanted order of LG mode. However, too strong an SA can stop the high-order mode beam from oscillating, since the width and radius of the ring-shaped LG mode are an increasing function of indices p and m, which bring a stronger loss to the corresponding mode. Based on this analysis, we turn to a focal-length combination of f1 = 100 mm and f2 = 51.8 mm, to reduce the SA to a level suitable for further higher mode operation. A highest-order LG0, ±75 is obtained by such an SA mode-selecting technique under fixed pump power of 1.03 W.

Published: December 2021

On the occasion of the centennial birthday of Mr. Chen-Ning Yang, many articles have summarized his important scientific influences on the development of contemporary physics. The author thinks that, as one of the greatest theoretical physicists, Mr. Yang in many scientific contributions has promoted the revolutionary progress of physics, and his unique style of science with deep and meaningful thoughts in academia has a long-term inspiration on developments of physics. Learning from Chen-Ning Yang's scientific thoughts, the author will put forward some personal opinions on the development trend of theoretical physics with his own experiences in researching theoretical physics for 30 years, e.g., studies of quantum open system, superconducting phase transition and cold atom physics by following Mr. Yang in Stony Brook from 1992 to 1994. This article will elaborate why it is important to pursue “beautiful or useful” theoretical physics through some concrete illustrations; Why could the good theories in fundamental physics be kept at a distance from experiments for some time? For the latter, this article also argues the relationship between theoretical prediction and experimental confirmation from the perspective of scientific methodology (philosophy). Focusing on “useful” theoretical physics-the applied theoretical physics, the author emphasizes that scientific research driven by the national demand, as well as free exploration, can also lead to important breakthroughs in fundamental physics.
pH-dependent 11° F1FO ATP synthase sub-steps reveal insight into the FO torque generating mechanism
Authors: Yanagisawa Seiga , Frasch Wayne D
Published: December 2021

Most cellular ATP is made by rotary F1FO ATP synthases using proton translocation-generated clockwise torque on the FO c-ring rotor, while F1-ATP hydrolysis can force counterclockwise rotation and proton pumping. The FO torque-generating mechanism remains elusive even though the FO interface of stator subunit-a, which contains the transmembrane proton half-channels, and the c-ring is known from recent F1FO structures. Here, single-molecule F1FO rotation studies determined that the pKa values of the half-channels differ, show that mutations of residues in these channels change the pKa values of both half-channels, and reveal the ability of FO to undergo single c-subunit rotational stepping. These experiments provide evidence to support the hypothesis that proton translocation through FO operates via a Grotthuss mechanism involving a column of single water molecules in each half-channel linked by proton translocation-dependent c-ring rotation. We also observed pH-dependent 11° ATP synthase-direction sub-steps of the Escherichia coli c10-ring of F1FO against the torque of F1-ATPase-dependent rotation that result from H+ transfer events from FO subunit-a groups with a low pKa to one c-subunit in the c-ring, and from an adjacent c-subunit to stator groups with a high pKa. These results support a mechanism in which alternating proton translocation-dependent 11° and 25° synthase-direction rotational sub-steps of the c10-ring occur to sustain F1FO ATP synthesis.

Activation of T cells requires a rapid surge in cellular protein synthesis. However, the role of translation initiation in the early induction of specific genes remains unclear. Here, we show human translation initiation factor eIF3 interacts with select immune system related mRNAs including those encoding the T cell receptor (TCR) subunits TCRA and TCRB. Binding of eIF3 to theTCRAandTCRBmRNA 3’-untranslated regions (3’-UTRs) depends on CD28 coreceptor signaling and regulates a burst in TCR translation required for robust T cell activation. Use of theTCRAorTCRB3’-UTRs to control expression of an anti-CD19 chimeric antigen receptor (CAR) improves the ability of CAR-T cells to kill tumor cells in vitro. These results identify a new mechanism of eIF3-mediated translation control that can aid T cell engineering for immunotherapy applications.
Perspektiver på å gå fra praktisk arbeid i klinikken til forsker, og på å forske der en arbeider i praksis
Authors: Areskoug Josefsson Kristina
Published: December 2021

Praksisnær forskning påvirkes av den kunnskap og forståelse som forskere og den som arbeider i klinisk praksis har om hverandres ståsted.  Gjennom felles forståelse, deling av erfaringer og samskapning kan forskningsprosjekter lede til holdbar forbedring, men det er vanlig at det i stedet er utilstrekkelig kunnskap om hverandres roller og kontekst. For eksempel, hvordan kommer den tenkte forskningsdesignen til å påvirke praksis og hvordan kan gjennomføringen av forskningen i praksis påvirke resultatene av prosjektet? Hva har høyest prioritet – forskningsprosjektet eller det praktiske arbeidet?
På samme måte som vi diskuterer behandlinger og resultater med pasienter og kolleger i klinikken, burde forskningsaktiviteter i klinikken diskuteres.

Valg av modalitet ved karundersøkelser: CTA vs. MRA
Authors: Skalmerås Maia Muri , Ellingbø Eirin , Rusandu Albertina
Published: December 2021

Keywords: MRA, CTA, Modality choice, Angiographic imaging, Mixed method

Sammendrag

Hensikt

Hensikten med denne studien var å undersøke hva som legges til grunn for radiologens valg av modalitet ved karundersøkelser. Dette med hensyn til at radiografen, med ansvar for berettigelse og selvstendig utførelse på CTA og MRA, bør kjenne til begrunnelsen for valgt modalitet.

 

Metode

Denne mixed method-studien bestod av en spørreundersøkelse med et nasjonalt perspektiv og et litteratursøk med et globalt perspektiv. Spørreundersøkelsen ble sendt til radiologer på offentlige sykehus i Norge. Litteratursøk ble gjennomført i databasene PubMed, Web of Science og Scopus, med søkeordene “MRA and CTA”, “MRA vs CTA” og “MRA and CTA and decision”.

 

Resultat

38 respondenter deltok i undersøkelsen, og 21 studier ble inkludert fra litteratursøket. I resultatet kom det frem flere viktige faktorer som påvirker valg av modalitet, blant annet tilgjengelighet, pasientens situasjon, bildekvalitet og diagnostisk verdi. Noen viktig funn er at modalitetsvalg avhenger av patologi og dens lokalisasjon, samt at det i stor grad tas hensyn til ønske fra den som henviser.

 

Konklusjon

Valg av modalitet er hovedsakelig basert på klinisk problemstilling og pasientrelaterte faktorer. Faktorer knyttet til selve modaliteten som strålingsbelastning, undersøkelseshastighet, tilgjengelighet, er også tatt i betraktning, men foretrukken modalitet vil endres i takt med teknologiutvikling. Det kan sess et behov for retningslinjer for å øke radiografens kompetanse.
‘She is like a Yakshini’

Published: December 2021

This paper looks at the importance of aggressive humour in the discursive construction of a ‘Yakshini’ character in a popular Chinese sitcom, Ipartment. The exaggerated, aggressive nature of such a stereotypical character undermines traditional cultural norms of Chinese femininity. Such characterisation of a heroine through aggressive humour in a popular sitcom reflects the fact that empowering women has become (or is becoming) more acceptable in contemporary China.
Exploring teacher-initiated humour in Academic English classes
Authors: Kholmatov Aziz
Published: December 2021

As a subject focused on teaching grammar forms needed for academic studies and genres of academic writing, Academic English may seem tedious at times. Sometimes it is a complex subject for students who are fresh to academia and it needs a peculiar didactic approach to provide a smooth transition of students from general to academic English writing at a university level. One of these approaches may be using humour during classes. The current research explores teacher-initiated humour in Academic English classes at the Westminster International University in Tashkent and its effects on students. Besides, it seeks answers to questions as to what types of humour teachers employ during the class mostly, how often they use humour, as well as students’ and teachers’ recommendations given on how to use humour in class. This study uses both qualitative and quantitative data extraction methods in the form of an online questionnaire with students and a semi-structured interview with teachers. Obtained results show that affective and social roles of humour, its quality of lessening anxiety, creates favourable conditions for students and teacher’s connectedness, which outweighs other humour’s roles. Besides, mnemonic and engaging roles of humour received solid support by the respondents. To obtain a more positive effect, it is recommended that teachers, when incorporating humour in class, apply a systematic approach. Humour should be planned beforehand and needs to be appropriate. Moreover, it should be used with moderation.

Published: December 2021

Humour plays a significant role in everyday interactions. Individuals perceive humour differently and experience various emotions, from exaltation to umbrage. Therefore, providing humorous communication in customer service is challenging. The aim of this study was to investigate the perception of humour in a tourism customer service context. In the first part of the study, representatives of Estonian tourism companies were asked their opinions about using humour in communication with their clients. They provided examples of the use of humour in customer service situations, which were then evaluated by potential tourists in the second part of the study. The results of the evaluation were analysed in relation to the respondents’ sense of humour. The findings were discussed in line with the four implicatures of humour.

Французское королевство и Русское государство в XI-XVI веках
Authors: Шишкин В.В. , Шварц И.
Published: December 2021

Представленная книга касается истории политических и династических отношений Франции и России в Средние века и в эпоху Ренессанса. Начало было положено еще в IX веке, когда франки впервые увидели россов, а чуть позже киевский князь и король франков боролись за руку византийской царевны. Замужество Анны Ярославны породнило Капетингов и Рюриковичей в середине XI столетия, о чем всегда помнили во Франции, но забыли на Руси. Авторы книги, Владимир Шишкин и Искра Шварц, рассматривают причины и обстоятельства возникновения взаимных интересов двух государств, начавшие отчетливо проявляться в XIII столетии, невзирая на то, что Запад и Восток окончательно разделились по религиозно-политическому принципу. В книге подчеркивается тем не менее, что процессы политической централизации и зарождения абсолютной монархии в обеих странах во многом протекали синхронно, равно как и то, что Россия уже в XV веке была плотно включена в большую европейскую политику, все более привлекая к себе внимание Франции. Особое внимание авторы уделяют попыткам создания военно-политического союза Франции и России и организации дипломатических и торговых контактов в XVI веке посредством личных отношений монархов дома Валуа и династии Рюриковичей.

Authors: Huh Jungwon , Doan Nhu Son , Mac Van Ha , Dang Van Phu , Kim Dong Hyawn
Published: December 2021

Load and resistance factor design is an efficient design approach that provides a system of consistent design solutions. This study aims to determine the load and resistance factors needed for the design of breakwater foundations within a probabilistic framework. In the study, four typical types of Korean breakwaters, namely, rubble mound breakwaters, vertical composite caisson breakwaters, perforated caisson breakwaters, and horizontal composite breakwaters, are investigated. The bearing capacity of breakwater foundations under wave loading conditions is thoroughly examined. Two levels of the target reliability index (RI) of 2.5 and 3.0 are selected to implement the load and resistance factors calibration using Monte Carlo simulations with 100,000 cycles. The normalized resistance factors are found to be lower for the higher target RI as expected. Their ranges are from 0.668 to 0.687 for the target RI of 2.5 and from 0.576 to 0.634 for the target RI of 3.0.

Calibration of load-resistance factors for the limit state design of front covered caisson breakwaters were presented. Reliability analysis of the breakwaters which are constructed in Korean coast was conducted. Then, partial safety factors and load-resistance factors were sequentially calculated according to target reliability index. Load resistance factors were optimized to give one set of factor for limit state design of breakwater. The breakwaters were redesigned by using the optimal load resistance factor and verified whether reliability indices larger than the target value. Finally, load-resistance factors were compared with foreign country’s code for verification.

Published: December 2021

Esta pesquisa teve como objetivo analisar as percepções sobre competências gerenciais observadas e esperadas do gestor público por concluintes de cursos de Ciências Contábeis de instituições de ensino superior privado de Belém (PA). Realizou-se uma pesquisa descritiva com abordagem quantitativa. A coleta dos dados ocorreu por meio de questionário e a análise por métodos estatísticos. Constatou-se que as competências gerenciais de maior expressividade foram “Saber ouvir”, “Ética e transparência”, “Cidadania e Democracia”, “Responsabilidade”, “Planejamento”, “Comprometimento”, “Visão estratégica”, “Liderança” e “Negociação”. Permite-se inferir que concluintes com ou sem experiência neste setor definem o gestor público como alguém com capacidade para ouvir, planejar e negociar, que seja comprometido, responsável, transparente e ético, que tenha visão estratégica e que exerça a liderança, a democracia e a cidadania na administração pública. Concluiu-se que no perfil do gestor público pesquisado são mais valorizadas as competências sociais e organizacionais (saber e saber-ser) do que as técnico-profissionais (saber-fazer).
Quando o Plantio de feijão nos atravessa: experiências e experimentações no ensino de ciências no campo
Authors: Santos Eliziane Santana dos , Freixo Alessandra Alexandre
Published: December 2021

Este artigo versa sobre um recorte de nossa pesquisa cartográfica, advinda de uma memória escolar vivenciada no ensino fundamental: o experimento que se propunha acompanhar o processo de germinação do feijão em um recipiente com algodão umedecido. A realização deste experimento provocou atravessamentos que causaram incômodos e nos mobilizaram a construir nossa escrita tomando esta memória como a potência da qual partem as reflexões em torno da noção de experiência (a partir dos escritos de Jorge Larrosa). Pensando nos atravessamentos que esta memória vem produzindo em nosso estar-sendo professoras, propomos como objetivo deste estudo acompanhar os processos de produção de memórias docentes, que visem expressar professoralidades no campo, considerando as entrevistas narrativas, articuladas a imagens visuais, como dispositivos para “fazer ver e fazer falar”, tomando Gilles Deleuze como inspiração. Neste artigo, chamamos à conversa uma professora de uma escola no campo, a fim de acompanhar a produção de diferenças que permeiam nossas professoralidades, por meio de nossas memórias e dos acontecimentos que nos atravessam. Compreender a diferença como base do nosso processo de (trans)formação professoral, nos permitiu refletir sobre o fato de que ela é responsável pelos acordos e tensionamentos estabelecidos nos docentes por meio da experiência, que é o mote deste plantio cartográfico. Através da partilha de experiências, pudemos perceber que há muito de coletivo em nossos atravessamentos pessoais, afetando nossas professoralidades, ainda que de maneiras distintas.

Published: December 2021

O artigo tem como objetivo identificar e analisar, no âmbito da Universidade Federal da Bahia, as ações e as políticas de internacionalização voltadas para sua inserção no contexto da educação mundial global. O texto pretende demonstrar como esta Universidade  tem historicamente realizado ações no sentido de se firmar como instituição que caminha na perspectiva da produção de conhecimento em sua relação com ações de internacionalização. Para isso, será apresentado um relato histórico dessas ações na Universidade desde sua fundação até o presente momento, com a aprovação do seu Plano de Internacionalização em 2018. A análise está alicerçada na revisão das políticas adotadas pelos governos brasileiros para fomento à internacionalização universitária até a criação do Programa Ciências sem Fronteira (PCsF) e Capes Print, do qual a UFBA foi e é partícipe, situadas enquanto significativas ações estratégicas para inserção das  Instituições Federais de Ensino Superior brasileiras no cenário acadêmico internacional. Isso incluirá,  certamente, o maior desafio apresentado pelos estudiosos sobre internacionalização: a proficiência linguística. Tal desafio será abordado, enfocando a principal medida local para seu enfrentamento: o Programa de Proficiência em Língua Estrangeira para Estudantes e Servidores da UFBA (PROFICI). Quanto à metodologia, trata-se de uma pesquisa descritiva de abordagem qualitativa e  baseada em revisão de literatura, tomando por base as informações em referências correspondentes, mas, principalmente, em informações contidas nos seus planos de desenvolvimento institucionais.

Introducing distinctive functional groups to expand the structural diversity and improve the intrinsic properties of parent molecules has been an essential pursuit in organic chemistry. By using perfluoroalkyl halide (PFAH) as a nontraditional, readily available, ideal 1,2‐difluoroalkenyl coupling partner, a defluorinative cyclization reaction of enamides for the construction of fluoroalkenyl oxazoles is first developed. The selective and controllable two‐fold cleavage of vicinal C(sp3)─F bonds in PFAH not only enables the introduction of a specific 1,2‐difluoroalkenyl moiety with ease but also results in the functionalization of two C(sp2)─H bonds of enamides without the need for metal catalyst, photocatalyst, oxidant, or light. The method can be applied to the late‐stage modification of complex molecules, synthesis of biological‐relevant oxazole analoges, and scale‐up synthesis, which all further highlight the real‐world utility of this protocol. Mechanistic studies reveal that the reaction possibly proceeds through a radical perfluoroalkylation, consecutive C─F bond heterolytic cleavage, and cyclization process. In addition, the in situ formed perfluoroalkyl radical which may also serve as an essential hydrogen abstractor.
Nitric Oxide‐Releasing Nanoscale Metal‐Organic Layer Overcomes Hypoxia and Reactive Oxygen Species Diffusion Barriers to Enhance Cancer Radiotherapy

Published: January 2025

Hafnium (Hf)‐based nanoscale metal‐organic layers (MOLs) enhance radiotherapeutic effects of tissue‐penetrating X‐rays via a unique radiotherapy‐radiodynamic therapy (RT‐RDT) process through efficient generation of hydroxy radical (RT) and singlet oxygen (RDT). However, their radiotherapeutic efficacy is limited by hypoxia in deep‐seated tumors and short half‐lives of reactive oxygen species (ROS). Herein the conjugation of a nitric oxide (NO) donor, S‐nitroso‐N‐acetyl‐DL‐penicillamine (SNAP), to the Hf12 secondary building units (SBUs) of Hf‐5,5′‐di‐p‐benzoatoporphyrin MOL is reported to afford SNAP/MOL for enhanced cancer radiotherapy. Under X‐ray irradiation, SNAP/MOL efficiently generates superoxide anion (O2−.) and releases nitric oxide (NO) in a spatio‐temporally synchronized fashion. The released NO rapidly reacts with O2−. to form long‐lived and highly cytotoxic peroxynitrite which diffuses freely to the cell nucleus and efficiently causes DNA double‐strand breaks. Meanwhile, the sustained release of NO from SNAP/MOL in the tumor microenvironment relieves tumor hypoxia to reduce radioresistance of tumor cells. Consequently, SNAP/MOL plus low‐dose X‐ray irradiation efficiently inhibits tumor growth and reduces metastasis in colorectal and triple‐negative breast cancer models.
Mitigating the Effect of High Overpotential during Al Deposition on Aluminium‐Graphite Battery Performance
Authors: Mukundan Charan , Drillet Jean‐Francois
Published: January 2025

This study investigates the impact of current density on electrode potential during aluminium (Al) dissolution/deposition step from/on an Al foil as well as the charge‐discharge behaviour of aluminium‐graphite batteries (AGB) in various AlCl3‐based electrolytes. Preliminary experiments in a cell with graphite blocking electrodes evidenced higher chemical stability of 1 : 1.5 Urea : AlCl3 electrolyte, followed by 1 : 1.5 TEA : AlCl3 and 1 : 1.5 EMIMCl : AlCl3. In Al−Al symmetric cells, current densities above 1 mA cm−2 led to a notable rise in overpotential up to 100 mV during Al deposition in both TEA : AlCl3 and Urea : AlCl3 electrolytes mostly due to low surface area of native Al foil. Similar trend was observed in AGB full cells, where higher overpotentials during Al deposition caused ‘incomplete’ AlCl₄− intercalation in natural graphite (NG), resulting in capacity fade at current densities in the range between 0.5 and 5 A g−1. By adjusting the upper cut‐off voltage (UCV) during charging step as a function of applied current value according to respective electrolyte stability, a significant improvement in specific capacity and energy density was achieved during charging and discharging steps. For instance at 1 A g−1, the specific energy density of AGB increased by 10 % in EMIMCl : AlCl3, 48 % in TEA : AlCl3, and an impressive 250 % in Urea : AlCl3.During long‐term cycling post‐UCV adjustment, the capacities of AGB increased by 10 %, 13 %, and 27 % for AGBs with EMIMCl : AlCl3, TEA : AlCl3 and Urea : AlCl3, respectively with a negligible capacity fade of less than 1 % for EMIMCl : AlCl3 and TEA : AlCl3, and a 9 % capacity fade for Urea : AlCl3.
