Corrupting data and sensing error, or how to ‘see’ digital images
Authors: Tyżlik-Carver Magdalena
Published: March 2024

In response to calls to forget and unthink photography this article considers the computational environment and its consequences for the image making. What is there to know about images that are networked and generated with data processing techniques rather than with light and chemistry? How to analyse images and read what they are and what they represent, beyond what is visible in the picture? The article argues that glitches while aesthetically capturing errors in the machine point to broader conditions of image making revealing systemic errors and not only its momentary technical failures. To explore digital images as affective phenomena to be sensed, the article looks at how glitch and its operations have been used by artists to generate digital images, and most importantly how they reveal computational systems as technical objects and affective infrastructures where discrimination is not an error but part of the system.
Cinema e pluralidade cultural: emprego de filmes árabes em práticas educativas preocupadas com a alteridade
Authors: Perinelli Neto Humberto , Baldacin Junior Alexandre Cristiano , Silva Ricardo Scucuglia Rodrigues da , Oliveira Edilson Moreira de
Published: March 2024

As sociedades orientais são alvo de olhar estereotipado e preconceituoso, segundo interpretação derivada de processo histórico denominado por Orientalismo, ou seja, discursos de naturezas diversas (literários, administrativos, pictóricos, filmicos), mas igualmente construídos pelos ocidentais, visando legitimar processos de dominação política e econômica. Reconhecendo a força dessa perspectiva e, a contar daí, recusando-a, é que o presente texto visa apresentar apropriação pedagógica que enfatiza a pluralidade cultural expressa em filmes árabes, tendo como referência outro paradigma, denominado por Orientalíssimo e associado ao esforço de conhecer sobre o Oriente a partir de discursos produzidos pelos próprios orientais. A pesquisa contou com abordagem qualitativa, natureza aplicada e engendrou descrição e explicação, valendo-se de investigações bibliográficas e documentais. Os aportes teóricos envolveram pensadores da educação, do cinema, da cultura e da estética. Conclui-se que “Caramelo” (2007), “O Edifício Yacoubian” (2006) e “Paradise Now” (2005) abordam temas como a mulher, a organização social e os homens-bomba, respectivamente, mas de modo a oportunizar visões baseadas na alteridade. Desta feita, configuram-se em narrativas cinematográficas importantes para o desenvolvimento de práticas educativas voltadas para reflexões sobre temas associados ao universo árabe, de maneira complexa, com mais profundidade e segundo ponto de vista baseado na voz do Outro ao qual se pretende conhecer.
Aspectos históricos e epistemológicos do conceito de função: um estudo sobre as ideias-base
Authors: Calado Tamires Vieira , Rezende Veridiana
Published: March 2024

A investigação aqui apresentada teve início com o desenvolvimento da dissertação de mestrado da primeira autora, naquela ocasião buscou-se investigar conhecimentos de estudantes da Educação Básica acerca da generalização da função afim. Os estudos foram aprofundados, e neste ensaio são apresentados aspectos histórico e epistemológico acerca da construção do conceito de função, explicitando suas ideias-base, ou seja, aquelas consideradas essenciais para a compreensão do conceito de função: correspondência, dependência, variável, regularidade e generalização. Para a elaboração do ensaio teórico foram considerados livros e textos científicos, artigos publicados em periódicos científicos, dissertações e teses. A investigação mostra que os primeiros registros envolvendo ideias de função foram desenvolvidos pelos babilônios há cerca de 2000 anos a. C. e contemplam as seguintes ideias-base de função: correspondência, dependência, variável e regularidade. No entanto, o processo de construção do conceito de função ocorreu de maneira lenta e as funções adquiriram uma formalização somente no século XVII, a partir da ideia de generalização das leis quantitativas em termos matemáticos, simbólicos e algébricos, o que fez com que a função assumisse um lugar de destaque dentro das ciências exatas. As ideias-base de função estiveram presentes e foram fundamentais no longo processo de desenvolvimento histórico e epistemológico desse conceito.

Authors: Guilherme Thais Helena , Carneiro Reginaldo Fernando
Published: March 2024

A participação de professores em grupos de estudos é uma possibilidade de formação e de reflexão sobre a prática docente que pode contribuir para o desenvolvimento profissional do professor que ensina matemática nos anos iniciais. O objetivo deste artigo foi identificar contribuições da participação em grupos de estudos para a formação desse profissional. Para isso, realizou-se um levantamento dos trabalhos sobre a temática publicados em três eventos importantes da área de Educação Matemática: Reunião Nacional da Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPED), Encontro Nacional de Educação Matemática (ENEM) e Seminário Internacional de Pesquisa em Educação Matemática (SIPEM), no período compreendido entre 2010 e 2019. Encontraram-se sobre o tema 19 trabalhos, que foram categorizados em: conteúdo matemático, formação inicial, análise de tarefas, parceria universidade-escola, mudança de prática docente no contexto escolar e formação de formadores. As análises evidenciaram que nesses grupos foram abordados conceitos e conteúdos matemáticos que, muitas vezes, são deixados em segundo plano, como a geometria e grandezas e medidas. Além disso, a participação dos professores permitiu que planejassem e analisassem, em conjunto, atividades para serem desenvolvidas em sala de aula. Também possibilitou o compartilhamento de experiências, a ajuda mútua, a colaboração, a formação de um espaço em que foram ouvidos e puderam discutir sobre desafios da prática, o que auxiliou no desenvolvimento profissional docente.
Educação Escolar Quilombola em Licenciaturas de Educação do Campo que formam professores de Matemática
Authors: Lima Aldinete Silvino de , Khidir Kaled Sulaiman , Fernandes Fernando Luís Pereira
Published: March 2024

O artigo tem por objetivo compreender como são estruturados os núcleos formativos de cursos de Licenciatura em Educação do Campo que formam professores de Matemática. O estudo é fruto de parte dos resultados de um projeto de pesquisa interinstitucional e buscou caracterizar os cursos de licenciatura que ofertam a formação de professores de Matemática para atuar nos anos finais do Ensino Fundamental e no Ensino Médio, em contextos socioculturais específicos. Nesse cenário, discute-se a formação de professores de Matemática em cursos de Licenciatura em Educação do Campo e princípios, conceitos e documentos legais que fundamentam e regulamentam a Educação Escolar Quilombola. Realizou-se uma análise documental, cujo corpus foi constituído pelos Projetos Político-Pedagógicos de quatro cursos de universidades públicas federais localizadas nas regiões Nordeste, Sudeste, Norte e Centro-Oeste do país. Por meio da análise de conteúdo temática, delinearam-se três categorias analíticas: formação geral e sociopolítica; formação matemática; e formação pedagógica integradora. Os resultados evidenciam que os núcleos formativos dos quatro cursos apresentam indícios de uma formação sociopolítica integrada à formação matemática. A análise aponta possibilidades para propor componentes curriculares que estabeleçam relação com a diversidade sociocultural dos povos quilombolas, não somente no componente Educação para as Relações Étnico-Raciais. Diante disso, reflete-se sobre as implicações da formação docente para atuação de egressos na Educação Escolar Quilombola e sugere-se a prescrição da formação sociopolítica em documentos de cursos que formam professores de Matemática para além dos contextos socioculturais investigados.
Movimentos Formativos no Clube de Matemática: o Projeto Orientador de Atividade
Authors: Borowsky Halana Garcez , Lopes Anemari Roesler Luersen Vieira
Published: March 2024

O presente artigo traz resultados de uma pesquisa de doutorado cujo principal objetivo foi investigar as relações essenciais do movimento de formação docente no projeto Clube de Matemática – na perspectiva da Teoria Histórico-Cultural. A investigação teve como sujeitos: acadêmicas de graduação, professoras da educação básica e estudantes de pós-graduação que atuavam no projeto. A produção de dados deu-se a partir do acompanhamento do trabalho do projeto denominado Clube de Matemática durante um ano, sendo os mesmos organizados a partir de episódios de formação, que constituíram três unidades de análises: o conhecimento científico, a organização do ensino e a formação humana. A análise dos achados possibilitou a compreensão de que as relações essenciais do movimento de formação estabelecidas em um projeto, ao promoverem nos sujeitos envolvidos um motivo que gere sentido à atividade de formação docente, tendo como premissa a coletividade, permitem compreendê-lo como um projeto orientador de atividade. Essa coletividade alcança-se quando a atividade realizada pelos sujeitos se dirige à realização de objetivos traçados pelo grupo que a compõe e cada um contribui, com seu esforço pessoal, para alcançá-los. Na coletividade, tal qual nos aponta Petrovski (1986) os objetivos são socialmente valiosos, ou seja, não se encerram no próprio grupo e essa deve ser uma premissa de projeto orientador de atividade, como um modo geral de formação docente na perspectiva da Teoria Histórico-Cultural.

Y és Z generációs fiatal közgazdászok vélekedése a mesterséges intelligenciáról
Authors: Dióssy Kitti
Published: March 2024

Életünk és mindennapjaink egyre nagyobb részére van befolyása a mesterséges intelligenciának (MI). A munkaerőpiacon már jelenlévő Y és Z generáció motivációja és attitűdje hatással van hosszú távon a vállalatok versenyképességére. Az MI előnyeinek felismerése mellett annak alkalmazása és az esetleges hátrányaihoz való alkalmazkodás is jelentős feladat. Kutatásomban arra fókuszálok, hogy feltárjam a fiatal közgazdászok gondolkodásmódját az MI-vel kapcsolatban, anonim kérdőívek segítségével (147 magyar, 105 amerikai válaszadó). Ennek érdekében amerikai (fejlett gazdaság és élen járó az MI-ben) és magyar (fejlett gazdaság, de nem jelentős az MI területén) fiatal közgazdászokat kérdeztem meg. Kutatásomból kiderült, hogy a két nemzet közgazdászainak gondolkodása között nem fedezhető fel szignifikáns különbség. Egyértelműen pozitívan és bizakodóan állnak az MI-hez, valamint annak rövid és hosszú távú hatásához. Érdeklődésük középpontjában azonban még nem szerepel az MI és annak megértése, de izgalmasnak találják. Fontosnak tartják a fejleszthető puha és a nehéz készségeket, amelyekkel felülreprezentált helyzetbe kerülhetünk az MI-vel szemben. A fiatal közgazdászok szerint teljesen nem fog megszűnni az emberi munka, csak átalakul, emiatt sem érzik magukat veszélyeztetve a munkaerőpiacon.
Artificial Intelligence for Simulation of Soot Distribution Inside Porous Filter Walls
Authors: Khýr M. , Plachá M. , Hlavatý T. , Isoz M.
Published: March 2024

The ability to estimate the influence of the accumulated solid matter on the performance of catalytic filters (CFs) in automotive exhaust gas aftertreatment leads to the ability to estimate the required filter regeneration frequency. The ability to perform such estimates fast and only from CFs microstructural data would allow for CFs microstructure optimization. In this work, we present an approach to estimate the distribution of soot deposited in the porous structure of CFs walls. The approach leverages methods of artificial intelligence (AI) and is based on convolutional autoencoders and deep neural networks. The resulting method is trained and tested on an artificial dataset that corresponds to a single pore in the CF wall. The dataset is prepared using our previously developed transient pore-scale model of particle deposit formation in the 3D microstructure of the catalytic filter wall. The developed AI model yields good results in terms of total amount of accumulated soot, but is less accurate in its distribution. As a result, using the estimated particle deposits to calculate the pressure drop and filtration efficiency of the artificial pore allows to estimate these two CF performance indicators with 33.6 % accuracy.
Model Order Reduction of Parameter-Dependent Particle Laden Flows
Authors: Kovárnová A. , Isoz M.
Published: March 2024

In this contribution, we extend our previously-developed framework for model order reduction of transport-dominated systems towards parameterized cases. The method combines the shifted proper orthogonal decomposition with interpolation via artificial neural networks. The resulting framework is an a-posteriori one, i.e., for parameterized systems, time-dependent solutions for several parameter values are required for the construction of the reduced-order model (ROM). The ROM can then be cheaply evaluated to predict the solution for previously unseen parameter values. The method is suitable for industry-relevant transport-dominated systems, such as particle-laden flows, where traditional mode-based methods, such as proper orthogonal decomposition (POD), often fail.

This study outlines a possible approach to aeroacoustics. An unsteady simulation of a 3D flow field in vicinity of a square cylinder is performed within the OpenFOAM framework using k − ω SST turbulence model. Afterwards, an in-house implementation of Lighthill’s acoustic analogy is discussed using FEM in 2D. The study concludes by presenting results both in the fluid and acoustic domains.
Special Shaped Low Drag Bodies of Revolution Without Boundary-Layer Separation and Stagnation Points on the Noses
Authors: Nesteruk I.
Published: March 2024

High Reynolds numbers allow solving many important inverse problems of high-speed hydromechanics with the use of the ideal fluid approach. The shapes of elongated axisymmetric cavities and bodies of revolution with the prescribed pressure distribution were calculated with the use of asymptotical series for flow potential and exact solutions of Euler equations. In particular, axisymmetric and 2D shapes with negative pressure gradients on their surfaces were proposed in order to avoid separation of the boundary layer and reduce the drag. Wind tunnel experiments have confirmed the absence of separation on some bodies of revolution similar to the trunks of aquatic animals. The proposed shapes with sharp concave noses (similar to the rostrum of the fastest fish) have no stagnation points, pressure and temperature peaks. These special shaped bodies moving near the water surface cause much lower vertical velocities on its surface and can have a low wave resistance. These facts open prospects of using corresponding hulls for underwater and floating vehicles. In supersonic flows, they can reduce overheating of the noses.
On Numerical Simulation of Fluid-Structure-Interactions using Precice for Coupling of OpenFoam with an In-House Solver
Authors: Pučejdl P. , Sváček P.
Published: March 2024

This paper describes numerical approximation of a fluid structure interaction problem. The interaction of the three dimensional turbulent fluid flow with vibrations of an elastic body are considered. The mathematical model of the problem is introduced. For numerical approximation of the elastic structure motion the Finite Element Method (FEM) is used whereas for the flow problem the Finite Volume Method (FVM) is employed. Mutual coupling of the two problems is considered and the preCICE numerical code is used for practical implementation of the coupled scheme. The structure dynamics is realized using an in-house C++ software and the flow is approximated using the OpenFOAM package. Verification of the in-house code is presented on several problems. Numerical results of flow-induced vibrations of a beam are presented.
Internal Wave Turbulence in Large Aspect Ratio Domains
Authors: Sibgatullin I. , Elistratov S.
Published: March 2024

Continuous stratification profoundly impacts the onset of hydrodynamical instabilities due to a unique dispersion relation. According to this relation, wave beams and wave energy propagate perpendicular to the phase velocity. It has been also observed that the dynamics of wave beams (webs of rays) in closed domains differ considerably from conventional ray tracing. In a general case, an attracting trajectory exists for the wave beams, referred to as wave attractors. These trajectories evolve due to the focusing/defocusing of wave packets upon reflection from the walls [1]. Owing to the high concentration of wave energy along these attracting paths, they are particularly susceptible to instabilities and serve as a source for the propagation of secondary waves. In our previous works, we demonstrated that if the aspect ratio of the motion is of the order of one, the transitions to turbulence can be effectively described using a laboratory toy-box model [2]. In such a laboratory model, turbulence originates from cascades of triadic resonances. This model represents one important case of natural flows. Another case involves large aspect ratio domains, where the horizontal scale is much larger than the vertical, yet buoyancy effects cannot be neglected. Previously, we described the peculiarities of linear regimes of large aspect ratio wave attractors and their instabilities at multiples of half the forcing frequency. Now, we present a full scenario of weak (not reaching overturning) instabilities, encompassing superharmonic and subharmonic frequencies at half the forcing frequency, along with cascades of triadic resonance instabilities in each half-harmonic frequency interval.
On Streamwise Vorticity Dynamics in a Wake
Authors: Uruba V. , Procházka P. , Duda D.
Published: March 2024

The streamwise vortices are detected experimentally in the wake behind a circular cylinder in Reynolds number 5 thousand on the top of Kármán vortex street dynamics. The stereo time-resolved PIV method has been used to detect the wake and streamwise vortices. The wake is moving periodically in spanwise direction due to Kármán vortex-street, consisting of vortices oriented in the cylinder axis direction. Both dynamical structures in the wake, the streamwise velocity component deficit and the streamwise vorticity concentration, are moving periodically in transversal direction with the same frequency, the vorticity concentration is shifted by a quarter of period before the velocity deficit in the shedding process. The streamwise vorticity is the most intense if the wake is in dead-end positions.
Timelessness à la Leftow
Authors: Page Ben
Published: March 2024

Brian Leftow has argued in significant detail for a timeless conception of God. However, his work has been interacted with less than one might expect, especially given that some have contended that divine timelessness should be put to death and buried. Further, the work that has critically interacted with Leftow does a very poor job at discrediting it, or so I will contend. As we shall see, the main reason for this is either because what is central to Leftow’s view is not affected by the objection, or because Leftow provides another way of getting his theory off the ground. Why, then, do so many objections miss the mark? I suspect it’s because many struggle to understand Leftow’s view and what is central to it. As such, one of the main goals of this paper will be to make Leftow’s account more accessible and to elucidate the main elements of the theory, whilst also providing responses to the main objections raised against his view. The overall result of this, I hope, will be a more fruitful examination of Leftow’s view in the future.

Dengue Hemorrhagic Fever is an infectious disease that often causes outbreaks. In Indonesia, the CFR of DHF in 2021 reached 0.96%, this figure increased from the previous year, which was 0.69%. Various efforts have been made to prevent transmission of the dengue virus, for example the use of larvicides for the eradication of Aedes, as a vector for transmitting dengue. The type of research in the Bio Larvicide B. Thuringiensis test is a pure experiment with a posttest only control design. The study was conducted to determine the effect of giving B. thuringiensis on the mortality of A. aegypti larvae in conditions that almost resembled their natural habitat. The study population was all larvae of Aedes instar III from the colonies of the Salatiga B2P2VRP Laboratory. Sampling was done randomly/simple random, ie all third instar larvae had the opportunity to be used as research and control samples. The mortality of Aedes larvae from the intervention of VectoBac WG (Bio Larvicide with the active ingredient B. thuringiensis) from each concentration at 60 minutes of observation, namely the mortality of Aedes larvae in the control group was 0%, at a concentration of 0.001 g/L was 93%, at a concentration of 0.002 g/L as much as 98%, a concentration of 0.004 g/L, 0.006 g/L and 0.008 g/L as much as 100%. The results of this study can be used as a reference for the use of VectoBac WG products as natural larvicides and an alternative in controlling mosquito vector populations.

Authors: Shamim Nik Mohamad , Ismail An Nur Nabila , Rosely Nurhidayah , Thani Ayu Kamareenna Abdullah
Published: March 2024

More concerns regarding the environmental impact are observed as the global travel industry continues to expand. The present study examined the correlation between ecological sustainability, tourists’ satisfaction, and the tendency to revisit past destinations to understand the impact of tourists’ perceptions regarding the environmental practices in travel destinations on overall satisfaction and subsequent revisit intention. A total of 200 local and international tourists participated in this study. The data collection process was conducted via self-administered questionnaires distributed in Langkawi, Malaysia. The results indicated a significant positive association between ecological sustainability and tourists’ overall satisfaction with respective trip experiences. A positive correlation also existed between tourists’ perception of travel destinations actively engaging in ecological sustainability practices and the reported satisfaction levels. Moreover, this increased satisfaction level positively impacted tourists’ intention to revisit the same destination in the future. The findings provided significant implications with high relevance to both destination planners and policymakers. Implementing and promoting effective ecological sustainability practices could not only enhance the attractiveness of travel destinations but also sustain high loyalty among tourists.
Neglected Trauma: The Lives of Women Dissidents and Émigrés in Daňa Horáková’s Memoirs
Authors: Antošíková Lucie
Published: March 2024

At the end of the 1970s, the Czechoslovak State Security, under the banner of the so-called ASANACE (‘sanitation’) campaign, used brutal means to deport leading dissidents abroad and break up the domestic opposition. As a result, many cultural figures emigrated, among them Daňa Horáková, a philosopher and collaborator of Václav Havel. Drawing on her memoir and the testimonies of other Czech female dissidents (and émigrés), the text reflects on the difficulties that life in dissent brought to women, as well as the pitfalls in which women were most at risk of becoming traumatized. Among the most risky moments was emigration and the uprootedness associated with it. Against the backdrop of research on emigration and trauma in literature, the present study offers an interpretation of O Pavlovi as a testament to the destructive impact of power.
Transgression and tenderness. Olga Tokarczuk in Comparative Perspective
Authors: Sobczak Izabela
Published: March 2024

The article is a review of the recently published by Routledge anthology Olga Tokarczuk. Comparative Perspectives, edited by Lidia Wisniewska and Jakub Lipski. As the first alngo-language monograph on Tokarczuk, supported by a concrete methodological proposal, it finds a significant place in the international discourse of the author. In the Polish literary discourse, which has been divided, it also opens new interpretative paths. The authors of the anthology, passing the boundaries of traditional comparative literature, highlight the epistemological aspect of Tokarczuk’s work, the way of understanding the “bizarness”, as well as the sources of her aesthetics. It turns out that the social dimension of Tokarczuk's prose, also gains a personal character, and the tender narrator, moving along the comparative path, has a chance to break out of abstraction towards subjectivity.
Diurnal and circadian regulation of opsin-like transcripts in the eyeless cnidarian Hydra
Authors: Santillo Silvia , De Petrocellis Luciano , Musio Carlo
Published: March 2024

Opsins play a key role in the ability to sense light both in image-forming vision and in non-visual photoreception (NVP). These modalities, in most animal phyla, share the photoreceptor protein: an opsin-based protein binding a light-sensitive chromophore by a lysine (Lys) residue. So far, visual and non-visual opsins have been discovered throughout the Metazoa phyla, including the photoresponsive Hydra, an eyeless cnidarian considered the evolutionary sister species to bilaterians. To verify whether light influences and modulates opsin gene expression in Hydra, we utilized four expression sequence tags, similar to two classic opsins (SW rhodopsin and SW blue-sensitive opsin) and two non-visual opsins (melanopsin and peropsin), in investigating the expression patterns during both diurnal and circadian time, by means of a quantitative RT-PCR. The expression levels of all four genes fluctuated along the light hours of diurnal cycle with respect to the darkness one and, in constant dark condition of the circadian cycle, they increased. The monophasic behavior in the L12:D12 cycle turned into a triphasic expression profile during the continuous darkness condition. Consequently, while the diurnal opsin-like expression revealed a close dependence on light hours, the highest transcript levels were found in darkness, leading us to novel hypothesis that in Hydra, an “internal” biological rhythm autonomously supplies the opsins expression during the circadian time. In conclusion, in Hydra, both diurnal and circadian rhythms apparently regulate the expression of the so-called visual and non-visual opsins, as already demonstrated in higher invertebrate and vertebrate species. Our data confirm that Hydra is a suitable model for studying ancestral precursor of both visual and NVP, providing useful hints on the evolution of visual and photosensory systems.
Estimating the slip rate in the North Tabriz Fault using focal mechanism data and GPS velocity field

This study delves into slip distribution on the North Tabriz Fault (NTF), a critical aspect of seismic hazard analysis due to its proximity to the Tabriz metropolis. The study operates within a uniform elastic half-space, maintaining constant values for fault geometry and regional rheological parameters throughout the research. To calculate strain boundary conditions, permanent and periodic global positioning system (GPS) data from the northwest region were utilized. The fault was constrained perpendicularly while allowing tangential movement, facilitating the determination of its annual slip rate using the boundary element method, with the Okada analytical model serving as the fundamental solution. The findings underscore the intricate relationship between the fault’s slip rate and boundary conditions, revealing a predominant right-lateral strike-slip motion. The study offers two slip rate assessments, obtained through earthquake focal mechanisms and GPS velocity data, yielding values of 5 and 5.5

, respectively. Importantly, the alignment of these calculated slip rates with paleo-seismological data underscores the credibility of the results generated via the boundary element method, distinguishing it as a reliable approach when compared to other numerical and analytical techniques. This research provides valuable insights into the behavior and slip dynamics of the NTF, which is pivotal for assessing seismic risks.

Published: March 2024

From the approval of COVID-19 mRNA vaccines to the 2023 Nobel Prize awarded for nucleoside base modifications, RNA therapeutics have entered the spotlight and are transforming drug development. While the term “RNA therapeutics” has been used in various contexts, this review focuses on treatments that utilize RNA as a component or target RNA for therapeutic effects. We summarize the latest advances in RNA-targeting tools and RNA-based technologies, including but not limited to mRNA, antisense oligos, siRNAs, small molecules and RNA editors. We focus on the mechanisms of current FDA-approved therapeutics but also provide a discussion on the upcoming workforces. The clinical utility of RNA-based therapeutics is enabled not only by the advances in RNA technologies but in conjunction with the significant improvements in chemical modifications and delivery platforms, which are also briefly discussed in the review. We summarize the latest RNA therapeutics based on their mechanisms and therapeutic effects, which include expressing proteins for vaccination and protein replacement therapies, degrading deleterious RNA, modulating transcription and translation efficiency, targeting noncoding RNAs, binding and modulating protein activity and editing RNA sequences and modifications. This review emphasizes the concept of an RNA therapeutic toolbox, pinpointing the readers to all the tools available for their desired research and clinical goals. As the field advances, the catalog of RNA therapeutic tools continues to grow, further allowing researchers to combine appropriate RNA technologies with suitable chemical modifications and delivery platforms to develop therapeutics tailored to their specific clinical challenges.
Methodology for Biomass Determinations and Microbial Activities in Sediments
Authors: Litchfield CD , Seyfried PL
Published: March 2024

Description

To date, there has not been a single source to which the investigator can refer for guidance on the techniques of microbial ecology that have been successfully adapted and tested in sedimentary systems. STP 673, Methodology for Biomass Determinations and Microbial Activities in Sediments, fills this gap. It presents new data that concentrate on how to apply to sediments the newly developing technique of microbial ecology.. It is hoped that ASTM's STP 673 will not only provide a central source for information on the state of the art in sedimentary microbiology, but that these procedures will serve as references for future testing, modification and improvement.
Medieval Sonic Violence on the Baltic Frontier
Authors: Olson Emma W.
Published: March 2024

This article explores the sounds of cultural encounter and colonial violence dramatically rendered in the 13th-century Chronicle of Henry of Livonia during the Baltic Crusades. In his chronicle, Henry claims to provide an eyewitness account of the sonic weapons the Germans deployed in their colonial project to dominate the Baltic landscape and its inhabitants: priests proselytized and preached sermons, dramatic performances instructed new converts in Christian stories, and soldiers and clerics played musical instruments and rang bells to Christianize soundscapes and terrify the pagans. Here, these episodes are recognized as a previously overlooked aspect of medieval Christian expansion and warfare: sonic violence. In part, this article intervenes against the persistent assumption that sonic violence is a distinctly modern phenomenon, aided by modern technologies and ideologies. Henry’s chronicle reveals a medieval man’s belief that sound could tangibly dominate others and his comfort in wielding that power against the Indigenous pagans. To show this, the examples of instrumental music in the chronicle are read alongside violent speech, drama, and silence. In his representation of these elements, Henry understands sound to be capable of enacting behavioral change and cultural domination over his enemies and of constructing a self-image of Christian authority. Ultimately, this article argues that Henry crafts an acoustic environment in which the German crusaders intentionally deployed unfamiliar musical instruments and aggressively dramatic missionary tactics against Indigenous peoples whose exotic, pagan sounds they countered with violent projections of their own sonic otherness.

Fashion photography that was previously distributed through printed media such as magazines, is now also distributed online through social media such as Instagram. Seeing these developments, this study aims to examine the form, visual appeal, and messages conveyed by fashion photography in Instagram’s content. This study uses a descriptive qualitative research approach with analysis of visual methods. Observations and interviews were used for data collection, sourced from fashion marketing accounts on Instagram, and from other Instagram users with photography and fashion education backgrounds. The results show that the form of fashion marketing photography varies depending on the concept and product being sold. Photos that are unique, different, and use good compositions are favored by the participants. Each photo has its own theme and message concept, but each photo shows that anyone can look cool and attractive if they use the fashion products shown in the photos. So, the fashion photography used in Instagram content should look unique and different, with good photographic composition, and easy-to-understand messages.
