Identifying conserved regions in lncRNA SChLAP1
Authors:   , Charania Zahra Sadruddin , Sell Christian
Published: November 2023

Over the last two decades, breakthroughs in sequencing technologies have revealed that mammalian genomes encode thousands of long non-coding RNAs (lncRNAs). The numbers of human lncRNAs that are dysregulated in diseases are rising at a rapid pace. Recent studies suggest that lncRNAs are critical regulators of both fundamental cellular processes and disease progression. Despite their significance as potential biomarkers and therapeutic targets, the molecular mechanisms of lncRNA function remain poorly understood. For example, SChLAP1 is a lncRNA that is seen to be upregulated among the aggressive subtype of prostate cancer and is critical for cancer cell invasiveness. However, the molecular mechanism behind SChLAP1's function is unknown. Emerging studies show that the function of lncRNAs is dictated by their sequence and structure. Therefore, we analyzed the sequence conservation of SChLAP1 across different species to help us identify functionally important domains of the lncRNA SChLAP1. The results identified that the 5'-end region of SChLAP1 is highly conserved across mammalian sequences. We, therefore, hypothesized that this region is functionally significant. By overexpressing full length and/or 5'-end alone, we tested the functional importance of conserved regions in lncRNA SChLAP1. Future studies include CRISPR/Cas-based deletions to investigate the mechanism of SChLAP1 in gene regulation and cancer.

Published: November 2023

The article presents an adaptation of the Gaevsky-Zhidkov method for estimating the balance of high-speed small-sized internal combustion engines using the idle characteristic, as well as propeller and external speed characteristics. The main task was to develop a test bench that provides high accuracy, repeatability of measurements and the ability to test internal combustion engines with working volume of up to 3.5 cm3 at shaft speeds of up to 37,000 rpm. The test bench makes it possible to determine the characteristics of the “engine-propeller”, the no-load characteristic, and also to carry out quick reconfiguration of the test facility when changing the internal combustion engine structure. As a result of the experimental study, the propeller characteristics of seven propellers, the no-load characteristics for the base electric motor and an electric motor with imbalance were determined. Using these results, the external speed characteristics of an internal combustion micro-engine with working volume of 2.5cm3 were compared for two levels of balancing.

The features of the stages of parameter design calculation for the formation of the initial design of the flow path of the compressor spool of a twin-shaft engine core of a gas turbine engine are presented and substantiated. The article contains recommendations for choosing values of the pump head coefficient, efficiency and other important parameters for the stages of medium-pressure and high-pressure spools at the stage of thermodynamic calculation. At the stage of design gas-dynamic calculation of the compressor at the middle diameter, typical distributions of axial velocity component and degree of reaction along the flow path of compressor spools should be taken into consideration. At the same time, it is necessary to provide requirements for reducing the flow velocity and static pressure coefficients in the rotor wheels and stator blades, head coefficients and Stepanov coefficients. The design gas-dynamic calculation of the compressor along the radius of the flow path is characterized by a variety of flow swirl laws at the inlet to the rotor wheels, distributions of the pressure increase and efficiency over the height of the blades. In conclusion, an example of a three-dimensional model of a compressor flow path taking into consideration the features of design calculation of the parameters of compressor spools of a twin-shaft engine core of a gas turbine engine on the basis of the appropriate flow path diagram in the meridional plane is presented.
The construction of meanings in a textual space: cognitive-lexical and cognitive-synergetic aspects
Authors: Baikadamova Assel , Bizhkenova Aigul , Sarsikeyeva Gulnar
Published: November 2023

The article presents the results of cognitive-synergetic and lexicological research of the meaning formed in the text. The research is based on the “meaning and sense” dichotomy of cognitive lexicology, as well as cognitive semantics position on the close connection of cognition and communication, relying on the principle of multilevel analysis, the unity of language and speech. The unity of cognition and communication manifests in the need to examine text meanings within a cognitive-discursive paradigm, which allows analyzing the dialogue between the author and reader, mediated by the text. It is in the process of interaction between the author (addresser) and reader (recipient) that the author’s ideas (intentions), as well as various shades of the author’s modality meaning, are transmitted, and new senses come forth in the course of the reader’s interpretation of the narrative. The paper used a combination of cognitive-synergetic methods (discursive, conceptual, interpretive methods, fractal analysis, conceptual integration, and associative experiment). The purpose of the study is to identify the meanings of the author’s and reader’s fields in the text semantic space, to determine their types and to analyze the ways of their formation. The article considers three main meaning formation models based on the analysis of the literary text semantic space of I. Esenberlin’s novel “Nomads”: 1) the author’s meaning model; 2) a model of the meaning formed in the reader’s interpretative activity; 3) invariant meaning, formed in the recipient’s mind as different from the author’s. The author shows that the processability of meanings, i.e., that they generate new meanings in the discursive activity of the author and the reader, is common to all these models. The article also focuses on cognitive integration, when the reader’s sense is formed by taking into account social factors of other eras, the new assessment and the development of the author’s text meaning from modern positions. The novelty of the conducted research lies in the fact that, for the first time, an attempt is made to identify and describe the author’s and reader’s meanings, formed in the context both of the historical period and current times, based on the material of a literary text. In addition, the novelty of the research consists of the author’s attempt to apply a cognitive-synergetic approach to the analysis of the text semantic space. This approach is used in the process of analyzing the discourses of the author and the reader, aimed at the formation of various types of meanings (conveying the author’s ideas and evaluation of implicit meanings in the reader’s perception). As a result of the analysis, it was established that the semantic space of the text is a dynamic field in which various meanings generated by the author and the reader interact. In order to review them, a set of methods were used to unfold new word meanings in the text.
Excitation of N2 Molecules as a Density Modifier: A Theoretical Approach
Authors: Villa J. , Rubio C. , Terencio T.
Published: November 2023

This work presents a theoretical exploration of modifying the volume and density of N2 gas molecules so as to feed gas balloons and zeppelin airships for flying purposes. This research aims to develop a gas system with a lower density than their non-modified ground state gas by studying the properties associated with excited state levels and their differences from the fundamental one. Then, this approach is achieved by altering the micro-molecular or electronic properties of N2 gas to assess the change at the macro-molecular level, such as volume and density. Density functional theory (DFT), time-dependent density functional theory (TD-DFT), and molecular dynamics (MD) computational methods are employed to look for the effects of excited N2 molecules on volume and density at standard conditions. As a result, a density decrease of 2.77% is achieved for the eighth excited state molecule set compared to the ground state system, indicating the feasibility of this approach. Contrasting this system with the traditional hydrogen gas used in zeppelins, N2 gas is a widely available, eco-friendly, and safe source (non-flammable) around Earth, strengthening its suitability as a source for high-tech applications.
Keywords: gas, excited states, DFT, TD-DFT, MD, volume, density modification.
Resumen
A través de este trabajo se presenta una exploración teórica acerca de la modificación del volumen y densidad del N2 gas con el objetivo de alimentar globos aéreos o aeronaves Zeppelin para propósitos de vuelo. Este estudio apunta hacia el desarrollo de un sistema gaseoso de menor densidad mediante el estudio de propiedades asociadas a niveles excitados de energía, contrastando con el sistema no modificado en estado fundamental. Esta estrategia es conseguida mediante la alteración la las propiedades micro-moleculares o electrónicas del N2 gas para evaluar cambios a nivel macromolecular, tales como el volumen y la densidad. Varios métodos computacionales, tales como la teoría de densidad funcional (DFT), la teoría de densidad funcional dependiente del tiempo (TD-DFT) y dinámica molecular (MD), son empleados para observar los efectos de moléculas excitadas de N2 sobre el volumen y densidad de este gas a condiciones estándar. Como resultado, se consiguió un decremento de la densidad del gas en un 2.77 % para el sistema en octavo estado excitado, comparado con el sistema en estado fundamental; lo cual es indicativo de la factibilidad de esta estrategia. Al contrastar el sistema de estudio con gases tradicionales como el hidrogeno gaseoso usado en zeppelins, el N2 gas es un recurso de amplia disponibilidad alrededor del globo, eco-amigable, y un material seguro (no flamable), lo cual lo hace un recurso ideal para aplicaciones de nuevas tecnologías.

Published: November 2023

Limonin A (L-A) was obtained from seeds of Citrus sinensis that were dried, grounded, and extracted using Soxhlet equipment. Initially, 100% hexane was used to eliminate fats, and finally, 100% dichloromethane was used in order to concentrate and isolate the compound. L-A recrystallization was performed using acetic acid. The purified fraction was identified as limonin according to spectral nuclear magnetic resonance (NMR) data. Two reactions were performed from L-A: Basic hydrolysis that acted on the A’ lactone ring producing a sodium salt of the lactone, and reduction with NaBH4 to reduce the carbonyl of carbon C-7 and generate the corresponding alcohol limonol. The structural modification of abundant secondary metabolites can become a source of new products with biological activity, useful in the pharmaceutical, cosmetic, and agrochemical industries of natural origin.

Ecuadorian Amazonian Fruits: A Proposal to Value Biodiversity and Promote Food Sovereignty
Authors: Capa M Sanchez , Gonzalez M Corell , Ramón C Mestanza
Published: November 2023

Fruits are characterized as a source of vitamins and minerals, recognized as an important part of a healthy eating pattern that reduces the risk of some chronic diseases. The Ecuadorian flora in the Amazon region is rich in edible fruits, but little is known about their characteristics and nutritional importance. At the same time, over the years, traditional knowledge about them has been lost. With this implication, this work pretends to describe a research proposal that values the biodiversity of edible fruits in the Ecuadorian Amazon, so that these underutilized products are conceived as more than merchandise. For this purpose, a narrative bibliographic review and a participatory observation were carried out. The research proposal included three stages i) the characterization of fruits traded in local markets; ii) an ethnobotanical study to identify the use and preference of the fruits; and iii) the analysis of bioactive compounds of at least 5 fruits prioritized according to the characterization and ethnobotanical study. The proposal stages generated research that converges the valuation of biodiversity, traditional knowledge, and nutritional potential of Ecuadorian Amazonian fruits.

Diesel Hydrodesulfurization and its Impact on the Fuel Market in Ecuador: A Review
Authors: Toro Paola , Casierra Jordan , Bastardo Ernesto , Ricaurte Marvin
Published: November 2023

This article examines the hydrodesulfurization process used to produce diesel with low sulfur content in Ecuador. The analysis covers the level of processing in the country, the quality of domestic diesel compared to other nations, and the technical and economic requirements of the process. It also explores the need to modify or upgrade catalysts to achieve deep hydrodesulfurization.. Unfortunately, the review found that sulfur content in Ecuadorian deposits is very high, with 3.53 MMkg produced in 2018. Despite improvements in the country’s refineries, diesel sulfur content has only been reduced to 110 ppm.. Ecuador regulates sulfur emissions through the Ecuadorian standard NTE INEN-1489 (2012). This norm classifies the fuel into three types, diesel #1 (3000 ppm), diesel #2 (7000 ppm), and premium diesel (500 ppm), following the use of diesel both in the industrial and transportation sectors. However, Ecuador seeks to adjust to countries with stricter regulations, such as the European Union. The standard that regulates sulfur emissions in this community is Euro VI, which limits the concentration to 10 ppm. One of the challenges in achieving international standards in the hydrodesulfurization units of the Ecuadorian refineries is to modify or improve the catalytic systems. Trimetallic catalysts, both supported and unsupported, can help overcome this challenge by decomposing the refractory molecules (e.g., dibenzothiophene and 4,6-dimethyldibenzothiophene) found in deep hydrodesulfurization. These catalysts can handle molecules that commonly used catalysts such as CoMo or MoW cannot. Therefore, proposals such as using trimetallic catalysts to achieve deep hydrodesulfurization levels are techno-economic options for Ecuador.
Keywords: diesel, sulfur, Ecuador, hydrodesulfurization, refineries, catalyst.

Az integráció dimenziói a magyar kis- és középvállalkozások működtetésében
Authors: Bajkó Norbert , Lencsés Enikő , Fülöp Zsolt
Published: November 2023

A kis- és középvállalkozási szektor minden nemzetgazdaság számára az egyik leginkább jelentősnek tekinthető. A nemzetgazdaságok foglalkoztatási szerkezetében jellemzően messze a legnagyobb szerepet tölti be, és a vállalkozások száma is jelentősen nagyobb ebben a szektorban, mint a nagyvállalkozások és a multinacionális vállalkozások szektoraiban. Ennél fogva egy erős, és teljesítőképessége minél nagyobb szintjén teljesítő nemzetgazdaság számára kiemelten fontos a kis- és középvállalkozások szektorának támogatása, valamint azon lehetőségek felkutatása, melyek a szektor teljesítményét minél jobban növelik a lehetőségek keretein belül.Cikkünk a kis- és középvállalkozások három jelentős folyamatával – név szerint a marketinggel, a kommunikációval, és az innovációval – foglalkozik, és az integráció köré építi a probléma feloldását. Alapvetésünk, hogy a kommunikáció, a marketing, és az innováció egyes elemeit minél magasabb szinten integrálja a vállalkozás a folyamatmenedzsmentjébe, annál hatékonyabban működtethetők mind a folyamatok, mind maguk az integrálni kívánt vezetési területek.Kutatásunk 81 vállalkozás segítségével valósult meg, a teljes szektorra nézve nem reprezentatív. Megállapításra került, hogy a kis- és középvállalkozások a marketing és a kommunikáció folyamatainak fokozódó integrációjával korlátolt mértékben érhetnek el sikereket, míg az innováció integrációja a menedzsment folyamataiba csupán kis mértékben javítja a vállalkozás folyamatmenedzsmentjének hatásfokát.
A gyógyszertárak versenyképességét befolyásoló fogyasztói motívumok települési dimenziókban
Authors: Hortolányi Árpád László
Published: November 2023

A gyógyszertárak egy speciális piacon versenyeznek, ahol amellett, hogy fontos közfeladatokat látnak el a rentábilis működésük biztosítása is kiemelt stratégiai szempont. A tartós jövedelmezőség elérése érdekében a szereplők, bizonyos kötöttségek mellett, ebben a szektorban is áthelyezhetik a működésüket egy centrum régiónak minősülő területre, azonban ez a lépés jelentős térségeket hagy ellátás nélkül. A kettős elvárás speciális stratégia kidolgozását követeli meg a gyógyszertáraktól, mellyel egyszerre biztosíthatják a nyereséges működésüket és az ellátás biztonsága sem sérül. Kutatásomban arra kerestem a választ, hogy a jellegében eltérő települések lakossága vonatkozásában izolálni lehet-e olyan jellemzőket, melyek segíthetik a gyógyszertárakat a sikeres versenystratégiájuk kialakításában. A primer kutatás során standard kérdőíves megkérdezéssel tártam fel a gyógyszertár választással kapcsolatos legfontosabb fogyasztói preferenciákat, melyeket a területi dimenziókkal összefüggésben vizsgáltam. Az elemzések eredménye alapján elmondható, hogy a különféle jellemzőkkel rendelkező területek fogyasztói sajátos elvárásokat támasztanak egy gyógyszertárral szemben, ezért a sikeres működéshez a térség lakosságának igényeit és preferenciáit integráló versenystratégia kialakítására van szükség.

The promotion of local product production and consumption is at the heart of both the European Union and Hungarian rural development agendas. In the effort to bolster the reach of small-scale producers, significant subsidies are allocated. Yet, the question of consumer preference for locally produced goods remains open. This paper presents a primary research study aimed at deciphering consumer habits within the Kecskemét microregion. It scrutinizes the channels through which consumers acquire their everyday food products and evaluates the proportion obtained from local sources. The study also probes the degree to which various factors - price, quality, eco-friendly packaging, and production locale and methods - influence consumer buying behavior. The central goal of this research is to provide an incisive snapshot of current purchasing trends in the Kecskemét area, thereby gauging the prevailing landscape for small-scale producers and short supply chains.

Primoz Trubar: ein zentraler Zeuge und Zeitgenosse der Reformation, Vermittler und Gestalter einer volksnahen Theologie im slovenischen Sprachraum
Authors: Giesemann Gerhard
Published: November 2023

Im Werk Trubars spiegeln sich alle Prozesse der mitteleuropäischen Reformation des 16. Jahrhunderts. Der Slowene beteiligt sich in erster Linie jedoch nicht an den theologischen Diskussionen der Zeit. Sein Ziel ist die Umsetzung evangelischer Erkenntnisse in das Verständnis seiner Landsleute. Einige Beispiele verdeutlichen dieses pädagogische Bestreben.
Украинский мыслитель? Григорий Сковорода
Authors: Koschmal Walter
Published: November 2023

Философское наследие двух богословов XVIII века − Феофана Прокоповича и Григория Сковороды − даёт возможность увидеть ‘несхожее сходство’ украинской и русской культур. У Сковороды сильнее, чем у Прокоповича, выражено западное влияние. Важными темами для него стали индивидуализм, предпочтение природы и натуры городу. Его стиль близок фольклорному. При всей амбивалентности своих взглядов, Сковорода никогда не противопоставляет украинское и русское, но созданное им украинское историко-культурное пространство отчётливо отличается от русского ортодоксального его времени.
Откуда есть пошла «беременная вдова»? Древнерусский источник очерков А. Герцена „С того берега”
Authors: Gonneau Pierre
Published: November 2023

Цeль этoй cтaтьи – вскрыть иcтoричecкий или литeрaтурный прoтoтип «бeрeмeннoй вдoвы», появившейся пoд пeрoм A. И. Гeрцeнa в его очерках C тoгo бeрeгa (1849–1850). Ее прототипом могла быть гeрцoгиня Бeррийcкaя Maрия Kaрoлинa, которая родила сына, Гeнриxa Шaрля д’Aртуa, грaфa дe Шaмбoра, 29 ceнтября 1820 гoдa, пoчти вoceмь мecяцeв спустя пocлe тoгo, кaк бoнaпaртиcт Лувeль убил eе мужа. Нo этoт пocлeдний прeдcтaвитeль cтaршeй линии фрaнцузcкиx Бурбoнoв никoгдa нe правил. В руccкoй иcтoрии «беременная вдова» может, на первый взгляд, напомнить о cудьбе императора-младенца Иoaннa Антоновича и eгo мaтeри, но речь идет лишь о частичной аналогии. Нaпрoтив, история рoждeния Cвятoпoлкa Oкaяннoгo в Пoвecти врeмeнныx лeт (в лeтo 6488/980) впoлнe укладывается в образ, созданный Гeрцeном. Таким образом, именно ПВЛ сознательно (или подсознательно) стала иcтoчникoм aвтoрa.

This study describes rates of violence victimization, perpetration, and witnessing in 6th–11th grade for a multisite sample (N= 3,466) of predominantly Black and Hispanic middle- and high-school students from urban areas with high rates of crime and economic disadvantage. Students completed surveys in middle and high school assessing teen dating violence, stalking, sexual violence and harassment, bullying, cyberbullying, and physical violence perpetration and victimization, as well as witnessing violence. The highest prevalence rates are observed most often in 8th or 9th grade. Youth reported high rates of witnessing serious assault and severe community violence throughout adolescence. These findings suggest that efforts to prevent violence among youth living in under-resourced communities need to start early and address community-level socioeconomic disparities.
Ius Constituendum Kewenangan Judicial Preview Di Mahkamah Konstitusi Republik Indonesia
Authors: Wada Igam Arya , Kurniawan Felix Alexander , Sinta Agnes
Published: November 2023

Menurut Pasal 24C ayat (1) UUD 1945, Mahkamah Konstitusi memiliki wewenang salah satunya menguji konstitusionalitas undang-undang atau judicial review. Akan tetapi, buruknya kualitas legislasi dan intensitas perkara judicial review yang tinggi tidak diimbangi dengan kewenangan Mahkamah Konstitusi yang memadai. Dalam kapasitasnya sebagai negative legislator, Mahkamah Konstitusi Republik Indonesia tidak diperlengkapi dengan wewenang untuk menguji konstitusionalitas rancangan undang-undang atau judicial preview sebagaimana yang ada dalam negara Perancis, Jerman, Austria, Hungaria, dan lain-lain. Diadopsinya kewenangan judicial preview dalam Mahkamah Konstitusi Republik Indonesia merupakan upaya preventif kelemahan-kelemahan dari judicial review. Eksistensinya dapat meminimalisir undang-undang yang berkualitas buruk, meningkatkan perlindungan hak-hak konstitusional warga negara, mengantisipasi undang-undang berumur pendek, mencegah ketidakpastian hukum, meminimalisir penundaan perkara di Mahkamah Agung untuk peraturan perundang-undangan di bawah undang-undang yang memiliki relevansi dengan undang-undang yang sedang diujikan ke Mahkamah Konstitusi, mengantisipasi pembangkangan (constitutional disobedience) Dewan Perwakilan Rakyat sebagai lembaga adressat putusan Mahkamah Konstitusi, serta mengakomodir partisipasi publik. Hasil penelitian menunjukkan urgensi amandemen kelima Undang-Undang Dasar Negara Republik Indonesia Tahun 1945 khususnya Pasal 24C ayat (1), serta perubahan keempat Undang-Undang Mahkamah Konstitusi dan Undang-Undang Nomor 12 Tahun 2011 tentang Pembentukan Peraturan Perundang-undangan jo Undang-Undang Nomor 15 Tahun 2019 tentang Perubahan Atas Undang-Undang Nomor 12 Tahun 2011 tentang Pembentukan Peraturan Perundang-undangan.

Published: November 2023

Penelitian ini bertujuan untuk mengetahui dan memahami prsoses pengangkatan sebagai hakim konstitusi yang dilakukan oleh ketiga Lembaga penyelenggaraan kekuasaan negara, Sebagaimana yang dijelaskan didalam UUD Negara Republik Indonesia Tahun 1945 di dalam Pasal 24c Ayat (3). memang didalam pengajuan sebagai hakim konstitusi, proses seleksi yang dilakukan oleh ketiga lembaga tersebut secara praktiknya tidak ada kesamaan di dalam melakukan prosedur pencalonan untuk menentukan calon hakim konstitusi  karena ini menjadi urusan dari masing-masing Lembaga yang mengaturnya. Hal ini tentunya sangat berpengaruh untuk menentukan kandidat hakim yang benar-benar memenuhi syarat sebagai hakim konstitusi yang memiliki kompetensi dibidangnya. Tak hanya itu pertimbangan etika moral dalam memilh sebagai hakim konstitusi perlu juga untuk dilihat.  begitu juga terkait dengan mekanisme pemberhentian sebagai hakim konstitusi. Apakah yang menyebabkan seorang hakim konstitusi dapat di berhentikan dari jabatanya. apakah karena meninggal dunia atau karena melakukan pelanggaran yang mencoreng nama baik institusi.  Namun bila melihat  di dalam pasal 23 ayat (2) huruf g seorang hakim konstitusi dapat di berhentikan apabila tidak lagi memenuhi syarat sebagai hakim konstitusi. Ketentuan ini memiliki makna yang kurang jelas karena tidak adanya penjelasan terkait tidak lagi memenuhi syarat. Hal ini dapat digunakan oleh segelintir kepentingan untuk mempolitisi seorang hakim konstitusi apabila tidak sejalan oleh Lembaga yang mengajukan sebagai hakim konstitusi. Dalam melakukan penelitian ini, guna menjawab dan menjelaskan persoalan ini maka peneliti menggunakan bahan dokumen seperti, buku, peraturan perundang-undangan, jurnal, serta sumber-sumber bahan lainnya. Kemudian disusun secara sistematis untuk selanjutnya dilakukan analisis supaya tecapai kejelasan yang akan di bahas. selanjutnya mengenai pengangkatan sebagai hakim konstitusi sebaiknya agar di atur didalam peraturan perundang-undangan tentang kesamaan didalam proses rekrutmen yang di lakukan oleh Lembaga supaya adanya kepastian dan kejelasan di dalam proses rekrutmen calon hakim konstitusi.

Memória e patrimônio artístico são pensados a partir de uma leitura da historiografia capixaba entrelaçada à análise documental do acervo da galeria. Os resultados revelam a potência da memória contida no acervo da GAP para a constituição do campo das artes no Estado, assim como apontam para a necessidade urgente de uma escrita da(s) história(s) da arte pensada a partir dessa localidade.
Brasilianas visuais
Authors: Turazzi Maria Inez
Published: November 2023

O artigo discute algumas experiências relacionadas à criação, apropriação e circulação de imagens e imaginários sobre o Brasil, a partir do colecionismo de antigas e novas brasilianas. Compreende-se a chamada ‘coleção brasiliana’ como um acervo pluridimensional sobre determinado lugar físico e social atravessado pelo tempo histórico, isto é, como uma coleção formada pela dinâmica dos processos de criação, preservação e difusão de bens culturais, materiais e imateriais, relacionados ao Brasil e aos brasileiros, no passado e no presente. Neste sentido, a patrimonialização de coleções identitárias e o alargamento da noção de brasiliana são analisados a partir da perspectiva teórico-metodológica oferecida pelas reflexões sobre memória, história e esquecimento de Paul Ricouer (1913-2005). Argumentamos que a natureza intrínseca de uma coleção do gênero contempla diversos suportes documentais, modos de colecionar e formas de interação entre os atores sociais envolvidos na escolha e promoção desses bens. Com esta perspectiva, apontamos a mudança provocada pelos meios digitais e sua ampla circulação através da internet para a visualidade, a difusão e a apropriação das brasilianas, a exemplo do que ocorreu com coleções similares (‘americana’, ‘canadiana’, ‘australiana’, etc.). Destacamos, nesse processo, o questionamento das “identidades nacionais” e os “trabalhos da memória” explorados por artistas e curadores contemporâneos.
