Published: June 2024

Epicuticular wax from the leaves of Tillandsia stricta Sol. Sims and Tillandsia usneoides (L.) from Grumari, Marica and Jurubatiba, Rio de Janeiro sandbanks was extracted into chloroform and n-hexane for analyses. The extracts were subjected to gas chromatography (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS) analyses. In the investigated species, the major n-alkane was found to be C-27. This study has shown that the relation of n-alkanes and fatty acids is a function of the species and the triterpenoids were only observed in the wax of T. usneoides. Phthalates: di-n-octyl phthalate (DNOP), di isobutyl phthalate (DIBP); Di (2-ethylhexyl) phthalate (DEHP), benzoic acid, adipic acid derivatives were also detected beyond of DDT in T. stricta from the Conservation Unit of Jurubatiba. The exposure of T. usneoides to vehicular emission resulted in the reversal of the relationship fatty acid: n-alkanes and the triterpenoids suppression. These results reflect the importance of plants in monitoring environmental purposes and their potential for DDT and phthalates indicator.

O domínio dos processos metabólicos envolvidos com o metabolismo do nitrogênio e a síntese de proteína microbiana em ruminantes é crucial para a profissão do Médico Veterinário. Mas por tratar-se de um tema de entendimento desafiador, muitas vezes não é totalmente compreendido pelos acadêmicos. Assim, objetivou-se com este trabalho mensurar o nível de aprendizado e dificuldades de acadêmicos de Medicina Veterinária da Universidade Federal do Pampa no entendimento do metabolismo nitrogenado em ruminantes. A partir dos resultados, aplicou-se metodologias ativas de ensino com novas avaliações do nível de aprendizado, taxas de acertos das questões e índices de reprovações extratificados por semestres e por sexo dos estudantes. Haviam dificuldades marcantes no aprendizado, que puderam ser superadas em parte com a aplicação das metodologias ativas. Estas contribuiram com melhora no entendimento do assunto abordado, aumento nas taxas de acerto das questões, e por consequencia aumento no nível de aprendizado. Porém, de forma isolada, metodologias ativas não solucionam os problemas de aprendizado, pois sem a dedicação dos estudantes os objetivos primordiais de ensino-aprendizagem não são alcançados.

A dificuldade no controle de plantas invasoras durante o estabelecimento do Tifton 85 prejudica sua produção. Com isso, objetivou-se avaliar diferentes tratamentos com herbicidas na pré-emergência de plantas daninhas em pastagem de Tifton 85 e verificar a diversidade da flora infestante e o índice de valor de importância das principais espécies. O experimento foi conduzido em Uruguaiana-RS com delineamento em blocos casualizados, com três tratamentos (Testemunha, Primatop e Primatop+Gliphosato) e dez repetições. Foram mensurados comprimento de estolões, massa seca e densidade de plantas daninhas e através do levantamento fitossociológico foi estimado o índice de valor de importância. A densidade das plantas daninhas foi superior na parcela sem utilização de tratamento, assim como a massa seca acumulada. Foram identificadas 10 espécies de plantas daninhas distribuídas em seis famílias. A mais representativa no que se refere a número de espécies foi a Poaceae com maior índice de valor de importância para o capim-arroz, tanto em pastagens implantadas sem a adoção de estratégia de controle de daninhas como adotando-se Primatop ou Primatop+Glifosato. O uso ou não de glifosato antes da implantação do Tifton 85 dependerá da infestação da área no momento do plantio, no entanto a aplicação de herbicida é indispensável.
The Kangâmiut dykes in West Greenland: markers of the tectono-metamorphic evolution of the southern Nagssugtoqidian orogen and its foreland
Authors: Korstgård John , Mengel Flemming , Glassley William , Sørensen Kai
Published: June 2024

The general extent and structural evolution of the southern Nagssugtoqidian orogen of West Greenland were first described by Hans Ramberg who based much of his paper on the deformation of the regional Kangâmiut dyke swarm. The southern boundary is marked by a transition from undeformed, discordant dykes in the south to highly deformed dykes and host rocks to the north. Our analysis of the southern Nagssugtoqidian orogen and its southern foreland uses a comprehensive compilation of available data and covers the area from Sisimiut in the north to Alanngua, south of Maniitsoq. This represents almost the entire c. 200 km latitudinal extent of the Kangâmiut dyke swarm and encompasses the complete range of Nagssugtoqidian overprint on these dykes and their country rocks. South of Itillip Ilua (Itilleq), the structural and metamorphic overprints on the dykes exhibit a considerable range in both intensity and P–T conditions between and even within outcrops. In contrast, north of Itillip Ilua, the rocks show more systematic gradual increases in the degree of structural overprints and metamorphic grade, culminating in the Ikertooq thrust zone where granulite facies rocks are brought southwards over amphibolite facies rocks. Currently, available age data from the Nagssugtoqidian orogen permits the identification of two metamorphic episodes at c. 1850–1800 Ma and c. 1780–1720 Ma. These groups of metamorphic ages are supported by recent 40Ar–39Ar ages from dykes in the same area, which cluster at c. 1860 Ma and c. 1740 Ma, respectively. Albeit geographically sporadic, both age intervals support a subdivision of the Nagssugtoqidian structural and metamorphic overprints across the southern Nagssugtoqidian orogen and its foreland into two distinguishable temporal phases. Further geochronological investigations may well, however, find these two phases to be part of a tectonic continuum. For now, it is thought that the older event records south-directed thrusting over the foreland and concomitant loading of this crust, at least as far south as Maniitsoq. This c. 1860–1800 Ma crustal shortening and thrusting likely also closed a depositional basin located at the current latitude of Ikertooq, which could have formed during an early-orogenic extensional event that enabled and accompanied the c. 2035 Ma emplacement of Kangâmiut dykes. Up to 50–100 Ma later, a younger (c. 1780–1720 Ma) phase of shearing and thrusting mainly affected the Itillip Ilua – Ikertooq area and likely overprinted elements of the former event. This local younger overprint generated a separate trend of distinctly northward-increasing deformation and metamorphism.
Challenging the past in Spain
Authors: Martínez Barahona Elena , García Arranz Mario
Published: June 2024

In recent decades, Spain has enacted two national laws on historical and democratic memory (in 2007 and 2022), alongside numerous laws at the sub-national level. The significance of these laws goes beyond their symbolic value; they not only contribute to collective memory but also acknowledge the plight of victims. This paper aims to analyze the factors influencing regional regulations on historical and democratic memory in Spain. Our focus will be on the drafting processes, exploring the political factors that shape their approval in different regions. Additionally, we will investigate regions that have yet to enact memory laws to understand the reasons behind the absence of such legislation.
MULTIMEDIA FRAMING OF BRECHTIAN CHIMERISM
Authors: Borkovska O.
Published: June 2024

Brecht's epic theater in its artistic diversity includes works that, having received multimedia interpretation, not only do not lose their artistic and aesthetic significance but also enhance it. This refers to B. Brecht's use of photo-epigrams from "Kriegsfibel", which became emblems of war. "Kriegsfibel" is the title of the second part of the great oratorio "Deutsches Miserere", which emerged as a result of Bertolt Brecht's creative collaboration with the composer Paul Dessau. Twenty-nine photo-epigrams formed the basis of the concert, which Brecht called "Deutsches Miserere" – "the great repentance of the German people". In this article, we examine the basic principles of the construction of "Deutsches Miserere", focusing on the functional features of the alienation effect in the work through multimedia and intermedia means. The focus lies on the interconnection and combination of different types of art: fiction, photography, cinematography, and music aimed at creating an original author's language. The article claims that the unifying principle that connects them is chimerism, which contributes to the effect of alienation and serves to provocatively and paradoxically comprehend and embody a certain theme or idea. In the triad of "principle – technique – medium", the leading artistic principle is the effect of alienation, one of the techniques of artistic transformation of reality is chimerism, and the medium is multimedia. The introduction of multimedia amplifies the alienation effect, and this allows us to consider the interaction of chimerism with intermedial means of expression, namely, it makes intramediality the sphere of existence of chimerism.
ORIENTAL MOTIVES IN CONTEMPORARY UKRAINIAN LITERATURE: IDENTITY AND IDEOLOGY
Authors: Kretova O. , Kretov P.
Published: June 2024

The work is devoted to the study of the correlation between the motives, images, symbols, stereotypes and clichés existing in modern Ukrainian literature, which outline the Eastern philosophical tradition, and the formation and transformation of identity at different levels and types. The consideration is carried out in the context of the emergence of the latest Ukrainian myth as a basis for national ideology. The purpose of the research is to outline the paradoxical nature of the general reception and individual explications of oriental motifs in modern Ukrainian literature on the occasion of those segments that can be defined through the predications of genre or mass. The article outlines the peculiarities of the reflection of oriental motifs in modern Ukrainian literature related to the dominance of the aesthetic and philosophical influences of the paradigm of postmodernism in the national tradition during the last decades. It also notes the connection between the reception of oriental motifs in Ukrainian modern literature and the politicization of modern public discourse on the occasion of the meaning-making East-West dichotomy. Political and ideological contexts of literary discourse and speech practices acquire signs of ambivalence and function as symbolic constructions. The dual nature of the reception of the image and philosophy of the East in the Ukrainian literary tradition and mass consciousness of both the metaphysical East and the geopolitical East has been clarified. The direction of transformation of oriental motives and images in the mass consciousness and literary usus in the context of finding the identity of different types and levels of generality in Ukrainian society and culture is also recorded. The liminal type of culture correlates with a divided society, and as a result the rational-educational interpretation of the image of the East as the antithesis of the West interacts with the postmodern fusion and mutual determination of East and West.
Tan Dun’s Water Music
Authors: Bittencourt Luís
Published: June 2024

This article aims to discuss the instrumentality of water in the repertoire for percussion, using the performance of the work Water Music (2004) by Chinese composer Tan Dun (1957) as a case study. Rooted in my own artistic practice (as percussionist, improviser and composer) in the performance of the work as the core of research process, this investigation also combined methods and theoretical perspectives from the fields of auto- and performative-ethnography (Wong 2008), in addition to semi-structured interviews with other percussionists specialists in Tan Dun’s water percussion works. Starting with an overview on water's integration into Western art music and its dynamic connection with percussion, this investigation intended to reveal, from the perspective of a percussionist, the intricate performative process involved in Tan Dun's Water Music. This investigation underscored the presence of a unique performance path, shaped by singular performative demands, in addition to creative and experimental artistic practices.
Magnetization reversal by multiple optical pulses for a photonic spiking neuron with the leaky integrate and fire model
Authors: Takagi Gaku , Murai Toshiya , Shoji Yuya
Published: June 2024

Photonic accelerators are anticipated to be the next generation of hardware processors, replacing traditional electronic accelerators. In current photonic accelerators based on artificial neural networks, photonic integrated circuits are incorporated with electronic integrated circuits to leverage their strengths: photonic circuits are used to perform linear calculations, while electronic circuits are used to perform nonlinear calculations. However, this architecture requires optoelectric conversion at each layer and is unable to leverage the superiority of light. We propose a novel photonic spiking neuron with a magneto-optical synapse and an all-optical spiking neural network. This study experimentally demonstrates that the magnetization reversal of CoFeB, which occurs during thermal accumulation owing to multiple optical pulses, is similar to the behavior of the leaky integrated and fire model of spiking neurons.

 Abstract
Data mining is one of the promising techniques in the process of reading and collecting data. Data is an important asset that can be used to find patterns, to project strategies in building business development processes. As with stock investment projections, it becomes important in choosing the right investment. In the process, stock investment must have aspects of the ability to predict stock price movements. However, this ability is limited by the ignorance of the public in managing these investments. One of the interesting stock investments, especially during a pandemic, is microsoft stocks. By comparing the results of linear regression methods and historical patterns, the resulting predictions can be much more accurate. From the microsoft stock price analysis dataset taken from 2018-2023, there are conclusions that microsoft's lowest stock price in November 2022 was 217,826, the highest stock in May 2023 was 309,948 and the average price was 260,787. From this calculation, it is obtained that Microsoft's stock prediction for May 15, 2023 uses a linear regression of 306.976 and a historical pattern of 260.136 so that there is a gap of 46.84. In terms of the data generated, the manual calculation gap with linear regression is much smaller than the historical pattern of 0.054 and from the manual calculation gap with the historical pattern is 46.786.

Implementation and Tuning of Momentum-Based Controller for Standing Balance in a Lower-limb Exoskeleton with Paraplegic User
Authors: Prieto Ander Vallinas , Keemink Arvid Q. L. , Asseldonk Edwin H. F. van , Kooij Herman van der
Published: June 2024

Lower limb exoskeletons (LLEs) are wearable devices that can restore the
movement autonomy of paraplegic users. LLEs can restore the users’
ability to stand upright and walk. However, most of the commercially
available and clinically used LLEs rely on the user maintaining balance
through the use of crutches. Recent improvements in the design and
control of LLEs and other legged robots allow for autonomous balance
control. In this work, we implement and evaluate a momentum-based
standing balance controller in the Symbitron LLE, consisting of eight
active (torque-controlled) and two passive joints. We first investigate
how gain tuning of the center of mass tracking control law, part of a
multi-task optimal controller, affects balancing performance. We apply
pushes on different device locations while in parallel-stance, compare
the response for different gains, and derive heuristic guidelines for
controller tuning given the control architecture, high-level goals, and
hardware limitations. Next, we show how this controller successfully
prescribes joint torques to the LLE to maintain balance with a
paraplegic user. The LLE can autonomously balance the user and reject
mediolateral and anteroposterior pushes in the order of 60 N at hip
height (and 40 N at shoulder height) while standing in parallel-stance,
staggered-stance with both feet at the same height, and staggered-stance
with a height difference of 0.05 m between the feet. This work presents
a viable control strategy for torque-controlled light-weight
under-actuated LLEs to keep the balance of paraplegic users during
stance, which is a necessary starting point towards autonomous balance
control during gait.

Recent years have witnessed significant advancements in cross-chain
technology. However, the field faces two pressing challenges. On the one
hand, hacks on cross-chain bridges have led to monetary losses of around
3.1 billion USD, highlighting flaws in security models governing
interoperability mechanisms and the ineffectiveness of incident response
frameworks. On the other hand, users and bridge operators experience
restricted privacy, which broadens the potential attack surface.

In this paper, we present the most comprehensive study to date on the
security and privacy of blockchain interoperability. We employ a
systematic literature review, yielding a corpus of 212 relevant
documents, including 58 academic papers and 154 gray literature
documents, out of a pool of 531 results. We systematically categorize 57
interoperability solutions based on a novel security and privacy
taxonomy. Our dataset, comprising academic research, disclosures from
bug bounty programs, and audit reports, exposes 45 cross-chain
vulnerabilities, 25 theoretical attacks, and 93 mitigation strategies.
Leveraging this data, we analyze 14 notable bridge hacks accounting for
over 2.9 billion USD in losses, mapping them to the identified
vulnerabilities.

Our findings reveal that a substantial portion (65.8%) of stolen funds
originates from projects secured by intermediary permissioned networks
with unsecured cryptographic key operations. Privacy-wise, we
demonstrate that achieving unlinkability in cross-chain transactions is
contingent on the underlying ledgers providing some form of
confidentiality. Our study offers critical insights into the security
and privacy of cross-chain systems. We pinpoint promising future
research directions, underscoring the urgency of enhancing security and
privacy efforts in cross-chain technology. The identified improvements
can mitigate the financial risks associated with bridge hacks, fostering
user trust in the blockchain ecosystem and, consequently, wider
adoption.

Plastic is the most frequently used material as a storage container by the public. Its various purposes, wide range of colors, types, and sizes, its versatility makes plastic a popular choice of material. One of the characteristics of plastic is its single-use, which implies it often being thrown away after one use and increases the amount of plastic waste in circulation. One of the most frequently found plastic wastes in circulation is HDPE plastic, which has become a pollutant that contaminates both land and bodies of water. Management of plastic waste is currently still ineffective, that eventually end up in landfills or burned. HDPE plastic waste can be processed and repurposed into a new product to produce jewelry designs. HDPE plastic that will be processed will undergo a meticulous and attentive process to ensure its quality and cleanliness, so it can remain safe when it has direct contact to human skin. Plastic that is one of the biggest pollutants in the world, can be repurposed and produced as a new product that can be used every day, to reduce the number of plastic pollutants.

Authors: ALMEIDA Gustavo Fonseca de , CHIODI Rafael Eduardo , GRIGOLETTO Fabio
Published: June 2024

O artigo apresenta um estudo realizado em uma cooperativa de segundo grau, localizada no Vale do Ribeira em São Paulo, criada para atender a política de compras institucionais de São Paulo sob o enfoque da compreensão dos desafios com a logística. Um roteiro semiestruturado foi utilizado nas entrevistas com gestores, produtores e entregadores. Doze organizações da agricultura familiar se uniram para produzir e entregar bananas em mais de duas mil escolas de São Paulo. Algumas dificuldades na entrega ponto a ponto foram observadas, como, por exemplo, a de concentrar todo o volume necessário para as entregas em um único entreposto, além de a exigência de apresentação de documentação comprobatória física a cada entrega, o que atrasava e dificultava o atendimento a um elevado número de rotas. A digitalização dos romaneios, e suas assinaturas em formato digital, proposta pelos entrevistados, pode agilizar os registros e atender a todas as escolas das rotas sugeridas. A organização social evidenciou a existência de uma lógica inclusiva, contra hegemônica de operação, embasada nos princípios da economia solidária, permitindo aos colaboradores atender aos compromissos assumidos e assim distribuir de forma mais justa a renda gerada com a produção de alimentos.

Rice is one of the most widely used staple foods in the world. However, its production is still very limited compared to the exponentially growing demand. Senegal, with an average consumption of 90 kg/habitant, is the third largest importer of rice in Africa. Aware of the impact of imports on the population, Senegal has set itself the objective of achieving food self-sufficiency by 2022 with an average yield of 5 tonnes/ha. ISRA, through its research, contributes to the achievement of this objective by developing adapted technologies. It is within this framework that a participatory evaluation of 30 new anther culture lines was conducted at the ISRA research station in Fanaye during the hot dry season of 2020. Surveys were conducted among producers through guided tours, while observations and measurements were made to collect agro-morphological parameters and characteristics preferred by producers. The agronomic results analysed and combined with the surveys made it possible to select the 10 best performing varieties. Among these 10 best performing lines, 6 were chosen by the producers. They are KF18134, KF18040, KF18068, KF18103, KF18124, KF18048, KF18005, KF18017, KF18001, KF18024. Crop yield is the first characteristic chosen by the growers. It was followed by short cycle characteristics, panicle load, low bird damage and medium height.
