Winnetou meets Gordon Gekko
Authors: McGonagill Doris
Published: February 2024

Doris McGonagill's contribution discusses the production of Tom Kühnel and Jürgen Kuttner's »Hasta la Westler, Baby!« at Deutsches Theater, Berlin, as a missed opportunity to engage in true dialectical reflection in the Brechtian tradition. Instead, the author argues, the political and self-referential play that combines various playlets and circus numbers with a musical revue, all presented with a strong dose of Karl May, superimposes complex discourses about colonization and victimhood in the context of German unification with slapstick entertainment and deliberately simplistic allusions to the American Old West.

Poetologien mehrdeutigen Erinnerns in der deutschsprachigen Gegenwartsliteratur
Authors: Eke Norbert Otto
Published: February 2024

Historisierungsprozesse als nicht allein erinnernde Konstruktionen des Vergangenen sind ein zentrales Feld der Gegenwartsliteratur. Literatur kartographiert, chronologisiert, kategorisiert und imaginiert Geschichte als Archäologie, die ,Fiktionen' produziert. Hier wiederum kommen Mehrdeutigkeiten ins Spiel, auch (vielleicht gerade weil) in literarischer Archäologie unausgesprochen stets ein Wissen darum mitläuft, dass nur der eine Zukunft hat, der auch eine Vergangenheit hat. Der vorliegende Aufsatz wirft vor diesem Hintergrund anhand der Erzählungen, Romane, und Multimediaprojekte Herta Müllers, Frank Witzels und Werner Fritschs den Blick auf die Poetiken dreier literarischer Kartograph*innen der jüngeren Zeitgeschichte, die von jeweils verschiedenen Seiten her mit eigenem Formwillen und Sound die Geschichte Rumäniens und Deutschlands im 20. Jahrhundert vermessen haben.

Das Karussell des Genießens und die allgemeine Ökonomie
Authors: Bohn Ralf
Published: February 2024

Das Karussell stellt in dreifacher Hinsicht eine Metapher intersubjektiver und intermedialer Ökonomie dar. Erstens verbindet es das Subjekt mit einem Sozius, dem Karussellpferdchen, und stellt so eine Beziehung von Menschen und Dingen her. Zweitens organisiert es ein affektives Spiel narzisstischer Stabilisierung durch Destabilisierung, von Selbst-Erfahrung durch Selbst-Verlust im Schwindelgefühl. Drittens realisiert sich im Karussell eine allgemeine Ökonomie zwischen dem Vergnügen des Konsums und dem Genuss asketischer Selbstaufhebung. Ralf Bohn beschreibt im Wechselverhältnis von Philosophie (Sartre) und Psychoanalyse (Lacan) sowie ausgehend von Max Weber die Ökonomie von Schuld im Widerstreit zwischen subjektivem Narzissmus und gesellschaftlicher Verbindlichkeit.

Die dunkle Seite des Spiels
Authors: Lösel Gunter
Published: February 2024

Spiel und Theater sind vielfältig verbunden, aber solange der Spielbegriff mit Harmlosigkeit assoziiert ist, nimmt er dem Theater Schärfe und Wirksamkeit. Gunter Lösel fragt deshalb nach einer Begriffserweiterung, die auch die dunkle Seite des Spiels umfasst. Zwischen Spiel, Wirklichkeit und Fiktion entwickelt er ein »Dreiweltenmodell des Theaters« und geht der Frage nach, warum die Spezies Mensch ein performatives Spiel entwickelt hat, in welchem sie sich negative Handlungen oder konflikthafte Situationen vor Augen führt. Durch Verbindungen zu Spieltheorie, Gaming, Philosophie, Performance-Studies und KI entsteht ein Reflexionsraum, der so den Widerspruch zwischen Harmlosigkeit des Spiels und Wirkungsmacht des Theaters auflöst.

Published: February 2024

This study evaluated the initial development of paricá (Schizolobium parahyba var. amazonicum) seedlings under different nitrogen rates with the application of Trichoderma spp., using a randomized complete block design in a 4x5 factorial scheme (strains and rates) with seven replications. The evaluated traits were plant height, stem diameter, leaf and stem fresh weights, leaf and stem dry weights, and aerial part dry and fresh weights. Trichoderma spp. strains did not satisfactorily promote paricá seedlings (Schizolobium parahyba var. amazonicum) under high nitrogen rates. However, the Trichoderma harzianum IBLF 006 WP strain was efficient only under low nitrogen availability.

Published: February 2024

Numerous patients with mild cognitive impairment (MCI) or Alzheimer’s disease (AD) are refractory to pharmacological treatment, and non-invasive brain neurostimulation has been investigated as another possibility for improving cognition. The performed meta-analysis and meta-regression verified predictors of efficacy, tolerability, and discontinuation of transcranial direct current stimulation (tDCS) for treating MCI or AD. The analyzed studies used the Mini-Mental State Exam, Montreal Cognitive Assessment, or Alzheimer's Disease Assessment Scale - Cognitive Subscale scores as outcome measures. Databases (PubMed, Embase, and Web of Science - primary collection) were searched, resulting in 12 published randomized and controlled trials. The risk of bias assessment was based on Cochrane Review recommendations, considering study characteristics. Other evaluated outcomes were the number of adverse effects (tolerability) and dropouts. Overall and anodal tDCS improved cognition compared to the sham protocol. Group comparisons did not show statistically significant differences for adverse effects and dropouts. Session duration was a response predictor, as stimulations of up to 20 minutes for ten days or more improved the outcome achievement. The AD diagnosis covariate also affected efficacy. The findings should be interpreted carefully in clinical practice because the stimulation effect may vary among subjects.

This study evaluated the incidence of unfilled second mesiobuccal (MB2) canals and periapical lesions in first maxillary molars using CBCT e-Vol DX software. Hence, 326 CBCT images of first maxillary molars of patients undergoing endodontic treatment were selected. The e-Vol DX software performed a retrospective review of these images, recording the presence or absence of MB2 canals, filling, and periapical lesions in first maxillary molars. Specific statistical analysis was performed at a 5% significance level. Unfilled MB2 canals were highly frequent in first maxillary molars and significantly associated with periapical lesions in the mesiobuccal root of these teeth (p<0.05). The CBCT e-Vol DX software effectively detected MB2 canals, and unfilled canals may be associated with periapical lesions.

Published: February 2024

Nuts are highly valued for their properties and are consumed worldwide owing to their health benefits, particularly, for the prevention and treatment of diseases, as well as a source of essential macro- and micronutrients. This study aimed to evaluate the effects of roasting on the nutritional value of nuts. Three types of nuts, raw and roasted almonds, cashews, and walnuts were selected from three well-known companies in Saudi Arabia. To analyze and evaluate the stability of macro- and micronutrients in nuts, modern separation and quantification methods, including inductively coupled plasma-optical emission spectrometry (ICP-OSE), were used to analyze and evaluate the stability of nutrients and heavy metals in nuts that are widely distributed and consumed.  The results of this study indicate that nuts have high nutritional value and an inverse roasting effect. Comparing the nutrient and metal contents of raw and roasted nuts provides useful information on the nutritional science of nuts consumed by well-known manufacturers in the Kingdom of Saudi Arabia. Further investigations of nuts are needed to draw firm conclusions regarding their association with the prevention of many different diseases.

Authors: Rocha Erik Carlos Ferreira da , Silva Rodrigo Oliveira da , Silveira Rebecca Impelizieri Moura da
Published: February 2024

Criado em 2008 com o intuito de viabilizar transações financeiras sem a necessidade de uma terceira parte, geralmente uma instituição financeira, a tecnologia blockchain despertou interesse como uma ferramenta para aprimorar a rastreabilidade de ativos em cadeias de suprimentos, devido às propriedades inerentes de ser um livro razão imutável e distribuído. No entanto, a aplicação dessa tecnologia nesse contexto ainda está em estágios iniciais, com poucos casos de uso estabelecidos. Dessa forma, este estudo teve como objetivo identificar e avaliar os potenciais benefícios do uso da tecnologia blockchain como ferramenta para rastreabilidade em cadeias de suprimentos. Para atingir esse objetivo, foi realizada uma revisão sistemática da literatura sobre o tema, destacando benefícios como automatização dos processos de rastreabilidade, redução de fraudes, auditabilidade e certificação através da implementação da tecnologia blockchain. Além disso, foram considerados desafios técnicos e de governança e lacunas quanto à distribuição de informação, certificação e custo ao se empregar essa tecnologia.
Deslegitimación del adversario y orientación ideológica: análisis de publicaciones de dos líderes políticos colombianos en Twitter
Authors: Borja-Orozco Henry
Published: February 2024

A través de diferentes medios de comunicación tradicional y digital, líderes y grupos que optan por el control social y político difunden sus discursos con el propósito de promover y fortalecer visiones ideológicas del mundo social en el que se exacerban las posiciones extremas de la ideología política. No obstante, la valoración política del espectro ideológico de izquierda y derecha no es generalizable, pues el énfasis positivo o negativo depende del contexto social y político. Este artículo describe las características ideológicas del discurso de dos líderes políticos reconocidos en Colombia por su orientación ideológica de izquierda (Gustavo Petro) y derecha (Álvaro Uribe), y la asociación con las estrategias de deslegitimación del otro. Para ello se realizó un estudio de tipo lingüístico descriptivo que compara en contexto los patrones lingüísticos de líderes políticos opuestos que publican en la plataforma digital Twitter (ahora X). Los resultados permiten identificar que el perfil léxico de la cuenta de Uribe se relaciona con temáticas de economía, violencia política, defensa de una ideología conservadurista, deslegitimación del oponente (Petro) y deslegitimación de grupos guerrilleros. Por su parte, el perfil de la cuenta de Petro está conformado por palabras asociadas a la ideología progresista, deslegitimación del oponente (Uribe) y deslegitimación de grupos paramilitares. Se concluye que la orientación política depende del contexto social y tiene como referente asociado un adversario político (y grupo ilegal en el caso colombiano), al que se dirige la estrategia de deslegitimación con el propósito de legitimar o desafiar el orden social establecido.
Parmenide e l’Uovo argenteo degli Orfici in Simplicio, Damascio e Proclo
Authors: Licciardi Ivan Adriano
Published: February 2024

When commenting on Aristotle Ph. 1.3, 187a1, Simplicius in Ph. 1.3, 146, 29–147,2 establishes an equivalence between the shining «silver egg» (ὤεον ἀργύφεον) of Orpheus (fr. 70 Kern) and the Parmenidean being or, rather, one of the determinations with which Parmenides, in the section of his Poem devoted to the so-called Way of Truth, indicates the ἐόν, i.e., «resembling the mass of a well-rounded sphere» (εὐκύκλου σφαίρης ἐναλίγκιον ὄγκωι – DK 28 B 8.43). The equivalence established here is found in the great digression about Parmenides (in Ph. 142, 28–148, 24), where Simplicius puts forward an interpretation of Parmenides that identifies the Parmenidean being-one (τὸ ἓν ὄν) with the intelligible (τὸ νοητόν), which, in another passages of the same commentary, is also qualified with the metaphysical concept of “unified” (τὸ ἡνωμένον) that is taken from Damascius. The aim of the present paper is to trace back the Neo-Platonic assumptions of this identification. In particular, we will focus on Damascius Pr. 2.55.40, 14–19 and 3.123.160, 1–3 Westerink, since these passages contain insights into the Orphic theology that is referred to as “usual”, “common” or “rhapsodic”, as well as a contextual “translation” of various Orphic concepts (e.g. ὤεον ἀργύφεον) in terms of Neo-Platonic metaphysics. The metaphysical transposition of the mythical image of the silver egg goes back, however, to Proclus (in Ti. 1.428, 8–9), who assumes the identity between Plato’s being (“being in the primary sense”, τὸ πρώτως [...] ὄν) and the Orphic egg (ταὐτὸν τό τε Πλάτωνος ὂν καὶ τὸ Ὀρφικὸν ὠόν). One cannot, at the same time, exclude a priori the possibility that the Orphic motif of the silver egg circulated in the Magna Graecia of Parmenides already from at least the 6th century BC. It is possible, as Colli hypothesised, that already Ibycus (who certainly knew Orpheus, fr. 25 Page) betrays a certain knowledge of it in fr. 4.4–5 Page, where we find the expression ἐν ὠέωι ἀργυρέωι. This article demonstrates that Proclus and Damascius embedded the Orphic concept of ὤεον ἀργύφεον into their Neo-Platonic metaphysics by showing its potential for speculative order.
And There Were the Plitvice Lakes. The Landscapes of the Croatian Lake District in the Romantic Journey Put na Plitvice
Authors: Pieniążek-Marković Krystyna
Published: February 2024

Put na Plitvice (The Road to Plitvice, 1860) is the first of the travelogue in Croatian language describing an expedition to the Croatian Lake District. The work of art is of significant “world-creating” and “culture-creating” value, introducing the Plitvice Lakes into the Croatian national text and into the national landscape, hence the biblical allusion in the title. It will therefore be a world-creating narrative, of bringing into existence and therefore giving a symbolic dimension of the work of art.I focus on the landscape-painting aspects of the text, understanding landscape as the manner of constructing and formulating the world, as a way of perceiving and incorporating it into cultural traditions. It is therefore rough, monumental, wild like a traversed space, which should be included in the category of picturesque and sublimity. Veber’s representation of nature illustrates how it was seen at the time within the framework of the national-revival programmes
Putopisna inskripcija Bosne i bosanskog u 19. stoljeću

Published: February 2024

The topic is romantic travelogues with the subject of Bosnia: descriptions andinsights into the perceived “reality” of the Bosnian area and people of the19th century presented through linguistic and stylistic means and on examples of selected travelogues from that period. New historical experiences of the writer opened the way for the emotional reception of collective practices of people, and this often leads to ahistorical conceptualization and long-lasting stereotypes. Considering that both linguistic activity and historical memory are mutual psychological processes, the diverse strategic character of the travel discourse through research shows that known cultural patterns can often deceive with their simplified form.

Assessment of heat transfer in a triangular duct with different configurations of ribs using computational fluid dynamics
Authors: Hameed Mohammed Hadi , Mohammed Hafidh Hassan
Published: February 2024

Numerical investigation was performed to improve heat transfer in triangular ducts using ribs of different sizes and shapes. Increased heat transfer may be achieved by the roughness in the duct surface, which is a prospective and successful method. It is shown that the sectional shape of the roughness given on the area exposed to heat has a major impact on the effective performance of heat transfer channels. This research will study the results of using different shapes and sizes of roughness components, such as triangular rib (e/W = 0.1, 0.2, and 0.3) as well as semi-circular rib (R/W = 0.1, 0.2, and 0.3). Likewise, the influence of rib width b (b/w = 0.2, 0.4, and 0.6) is examined using computational fluid dynamics for variable Reynolds number (1,000 < Re < 1,800) at fix rib height (e/W, R/W = 0.1). ANSYS FLUENT 2020 R1 is used to model the heat and the flow dynamics in roughened ducts. The best performance was for the semi-circular ribs. At a Reynolds number of 1,200, the optimum ratio of enhancement (ε) for the semi-circular rib sample e = 0.2 × W was 1.717. Additionally, sample 4 has the greatest Nusselt number across all Reynolds numbers and is the best-shaped sample. Furthermore, the pressure drop and the friction factor also increase when the rib width is increased, the sample (p = 0.2 × W) highest pressure drop and coefficient of friction values.

Heterodyne detection based on interband cascade lasers (ICL) has been demonstrated in a wide range of different applications. However, it is still often limited to bulky tabletop systems using individual components such as dual laser setups, beam shaping elements, and discrete detectors. In this work, a versatile integrated ICL platform is investigated for tackling this issue. A RF-optimized, two-section ICL approach is employed, consisting of a short section typically used for efficient modulation of the cavity field and a long gain section. Such a laser is operated in reversed mode, with the entire Fabry–Pérot waveguide utilized as a semiconductor optical amplifier (SOA) and the electrically separated short section as detector. Furthermore, a racetrack cavity is introduced as on-chip single-mode reference generator. The field of the racetrack cavity is coupled into the SOA waveguide via an 800 nm gap. By external injection of a single mode ICL operating at the appropriate wavelength, a heterodyne beating between the on-chip reference and the injected signal can be observed on the integrated detector section of the SOA-detector.
A physically consistent AI-based SPH emulator for computational fluid dynamics
Authors: Amato Eleonora , Zago Vito , Del Negro Ciro
Published: February 2024

The integration of artificial intelligence (AI) into computational fluid dynamics (CFD) has significantly expanded the scope of fluid modeling, allowing enhanced analysis capabilities and improved simulation performance. While Eulerian methods already benefit extensively from AI, notably in reliable weather prediction, the application of AI to Lagrangian methods remains less consolidated. Smoothed particle hydrodynamics (SPH) is a Lagrangian mesh-less numerical method for CFD with well-established advantages for the simulation of highly dynamic free-surface flows. Here, we explore an application of AI to SPH simulations, utilizing an artificial neural network (ANN) to estimate hydrodynamic forces between particle pairs, learning from SPH-simulated results. A model of this nature, which emulates the mathematical representation of physics, is termed an emulator. We examine the physical significance of the emulator, presenting its applications in benchmark tests, assessing its faithfulness to traditional SPH simulations, and highlighting its ability to generalize and simulate test cases with varying levels of complexity beyond its training data.

Published: February 2024

Acceptance of one’s gender identity and congruence between one’s gender identity and outward appearance are associated with less adverse mental health symptoms, and greater life and job satisfaction. However, trans people are subject to human rights violations, hate crimes, and experience higher unemployment and poverty than the general population. Trans people often feel that they are citizens who are not allowed to be themselves and practice their authentic identity. Many biased treatments of trans people could be attenuated if legal protections and inclusive workplace practices were in place.

Published: February 2024

Artificial intelligence (AI) is rapidly revolutionizing our daily lives, as it automates mundane tasks, enhances productivity, and transforms how we interact with technology. We believe it is inevitable that AI will soon become a crucial tool in common research practices, from data analysis to writing papers. Here we explore how this transition is occurring in the field of mass spectrometry-based metabolomics, a rapidly growing area of science. Metabolomics focuses on studying small molecules in biological systems, offering valuable insights into metabolic processes and their impact on health, diseases, and physiological conditions. With the remarkable advancements in sequencing technologies and the exploration of the microbiome, the combination of sequencing and metabolomics presents profound opportunities to understand biological complexity. Incorporating AI is promising to unlock new possibilities for expanding the realms of scientific discoveries. In this review we specifically focus on the current trends in the application of AI in metabolomics research. Existing practices are examined and a perspective on future directions for integrating AI into metabolomics research is presented.
Some Aspects of the Theory of the Beating Process
Authors:   RESEARCH DEPT., THE E. B. EDDY COMPANY, HULL, P. Q., CANADA, Gallay W.
Published: February 2024

Three factors involved in the strength of paper are discussed (1) the strength of the fibre, (2) resistance to failure by slippage of fibres and (3) interfibre bonding. The objectives of beating are considered to be the production of (1) the best conditions for maximum interweaving of fibres in the web and (2) the best conditions for bonding between fibres. Both of these desirable attributes must be produced with maximum possible avoidance of gross damage to the fibre. The matters are discussed in some detail. Particular attention is drawn to other closely related topics for example, fibre swelling and plasticisation, interfibre adhesion in suspensions and flocculation and the relationship of tearing strength to beating.

This paper summarises three related investigations the flow characteristics of pulp suspensions, the strength of dilute fibre networks and the flexibility of individual fibres. When pulp flows through a circular pipe, three regimes of flow (designated as laminar plug, mixed and turbulent flow) may exist, separated by two transition velocities, which, with relatively long-fibred pulps, are sharply defined. Plug flow is characterised by the development of a fibre free wall layer whose existence can be demonstrated in several ways. Mixed and turbulent flow involve the breakdown of the fibre network by the turbulent stresses . Relationships between flow properties and concentration and types of pulp are discussed. Pulp suspensions can exhibit the Weissenberg effect, which may be taken as evidence of their visco-elastic nature. The tensile strength of pulp suspensions at concentrations down to 0.2 percent. and less is measured by a simple experimental technique. It increases with fibre concentration, fibre length, extent of delignification and of beating. A close correlation is found between the network strength at 0.8 percent. fibre concentration and the conventional wet-web strength at 15 20 percent. It is concluded that the networks and wet webs are held together mainly by interfibre friction. The predicted correlation between the static network strength and the friction factor in turbulent flow is shown to exist. A method of measuring the flexibility o)f individual fibres is described. The method is based on a classification of rotational orbits of the fibres in laminar shear and provides a measure of the distribution of fibre flexibility in a given sample. It is shown that flexibility increases with increased fibre length, decreased amount of residual lignin and with beating. By means of a series of measurements on pulps cooked to various yields a correlation is shown between fibre flexibility, network strength and the ability of the fibres to suppress turbulence in water.
The Fine Structure of Cellulose Fibrils
Authors:   RESEARCH AND DEVELOPMENT DIVISION, AMERICAN VISCOSE CORPORATION, Rånby Bengt G.
Published: February 2024

The exceptional stiffness of cellulose chains in solution is discussed in relation to the configuration and the possible conformations of the chains and to postulated intrachain hydrogen bonds. The cellulose chains have a strong tendency to aggregate into partly crystalline fibrils, in native plant celluloses appearing as flat ribbons of about 100 Å. Width and of indefinite length. Electron microscopy of thin sections of plant cell walls has given good evidence that these fibrils are of native origin they are embedded in hemicellulose, lignin, etc. and not artefacts from the preparation of specimens. The crystallinity of the fibrils and their accessibility to, say, swelling or hydrolysis varies with the biological origin of the material and is also affected by the pretreatment. The higher lattice order and the lower accessibility of cotton cellulose fibrils compared with wood cellulose are particularly well studied. When hydrolysed with dilute mineral acid, the native cellulose fibrils (`micelle strings’) are attacked at certain points and degraded into rodlike fragments (`micelles’) . The fact that extraction of hemicellulose from wood holocellulose and subsequent drying decreases the length of the resulting micelles is discussed in relation to lattice distortion in the fibrils (formation of disordered regions and slip planes) due to the collapse (`crushing’) of the cell wall.

The polysaccharides that accompany cellulose in the plant cell wall consist mainly of xylans, glucomannans, arabogalactans and related polymers containing residues of L-rhamnose. The xylans are of various types, all of which have as a common feature chains of ß-1,4′-linked xylopyranose residues. To these are attached as side-chains various residues including, amongst others, L-arabofuranose, D-glucuronic acid, 4-0-methyl-D-glucuronic acid, 2-(ß-D-xylopyranosyl)-L-arabofuranose, D-galactose, L-galactose. The xylans differ amongst themselves in the nature of the side chains and in their relative proportions. From the marine algae, another type of xylan has been isolated having both βI,3′- and βl,4′-linked xylose residues in the main chain. Consideration is given also to the main structural features of some galactomannans, glucomannans and arabogalactans that accompany xylans in many groups of cell wall polysaccharides.

Es suficientemente conocido el valor nutricional y las características químicas de la especie Euterpe oleracea; sin embargo, en la región Pacífica colombiana existen otras especies poco conocidas de la familia Arecaceae con potencial valor en cuanto al contenido de compuestos bioactivos. El principal objetivo de este estudio es determinar el contenido de compuestos fenólicos y la capacidad antioxidante de tres especies silvestres de la familia Arecaceae (palmas). Para el cumplimiento de este objetivo, las partes comestibles de los frutos maduros de Euterpe oleracea, Oenocarpus bataua y Oenocarpus mapora, se sometieron a extracción asistida por ultrasonido, empleando mezclas hidroalcohólicas con diferentes concentraciones de ácido acético como disolvente para la extracción. La optimización del proceso de extracción mediante un diseño central compuesto (DCC) mostró que las mejores condiciones de extracción se obtienen con una concentración de etanol del 65 % (v/v) y una concentración de ácido acético del 0.5 % (v/v). Los resultados del proceso de purificación mediante cromatografía de columna mostraron que tanto el extracto crudo como la fracción enriquecida de O. mapora, presentaron el mayor contenido de compuestos fenólicos (137.5; 224 g EAG/g ES), el mayor contenido de antocianinas totales (1.7; 3.5 mg EC3G/g ES) y la mejor capacidad antioxidante por el método de DPPH (538; 1879 µmoles ET/g ES) en comparación con los mismos extractos y fracciones de O. bataua y E. oleracea.

Published: February 2024

This study shows the modeling of the convective drying operation of quinoa (Chenopodium quinoa Willd. var. Hualhuas) grains implemented in the General Algebraic Modeling System (GAMS) software. The proposed model was based on Fick’s second law. The drying experiences were carried out using a pilot-scale oven. The drying air conditions were: 40, 60, and 80°C and 0.2 and 0.7 m s-1. The mathematical modeling was employed to describe the behavior of the drying operation according to variations of the average moisture over time. The effective diffusivity of moisture and mass transfer were studied for the different operating conditions. The model was validated by experimental data. It was possible to model the quinoa grains drying process, obtaining a high precision between the experimental and estimated values. Quinoa drying curves can be represented properly by the studied model. In the operating ranges tested, the effective diffusivity values of moisture were between 2.52 10-10 and 1 10-9 m2 s-1 and the mass transfer values were between 7.20 and 11.47 cm s-1. The effective diffusivity (Deff) showed significant differences (P<0.05) with the speed of the drying air, while the mass transfer coefficient (k) was significantly affected (P<0.05) by the temperature of the drying air.

Published: February 2024

Los ecosistemas de páramo son muy importantes debido
a que son una fuente hídrica única en el mundo, en donde
habitan diversas especies de flora y fauna, sin embargo,
son pocos los estudios que se centran en el cambio que están
sufriendo estos ecosistemas. El propósito del artículo
es identificar la relación entre variables meteorológicas y
cambios de cobertura del páramo de Chingaza. Para esto,
se evalúa la generación de un modelo de espacio de estados
basado en las variables climatológicas de temperatura,
humedad y precipitación, para describir el cambio en el
área de cobertura del páramo de Chingaza (Colombia)
entre los años 2009 y 2019. A estas series de tiempo se les
realizo análisis de correlación, pruebas de Dickey-Fuller,
prueba de ruido blanco o Ljung box test y modelos ARIMA
para verificar su nivel de predicción, utilizando el
software R. Los datos obtenidos muestran que las variables
de temperatura y vegetación de páramo y subpáramo son
las que mejor explican el cambio en el área de cobertura de
este ecosistema. Se obtuvo un modelo óptimo con un R^2
de 0,4874, que explica el 48 % del cambio de cobertura
de vegetación de páramo y subpáramo. Estos resultados
evidencian que sí es posible generar un modelo de espacio
de estados del cambio en el área de cobertura del páramo
de Chingaza, explicado por la variable climática de temperatura,
que se convierte en una herramienta base para
futuros estudios que integren otras variables.

Avant-Garde Europe in War: Wyndham Lewis, the Vorticist Shakespeare and the Timon of Athens Portfolio
Authors: Perni Remedios
Published: February 2024

This article examines the relationship between Wyndham Lewis’s Vorticism movement and Shakespeare, focusing on Lewis’s appropriation of Shakespeare’s play Timon of Athens and its impact on Vorticism’s visual aesthetics. In analysing Wyndham Lewis’s avant-garde approach, this article contrasts it with other artistic movements of the time —namely, Futurism and Cubism— and explores Lewis’s interest in the “automaton” and the “machine”, and how this fascination is linked to his reading of Shakespeare and his views on World War I. Overall, the paper demonstrates how Shakespeare’s work played a significant role in the development of Vorticism’s unique aesthetic vision during a time of great social and political upheaval.
búsqueda de la flexibilización de Mercosur
Authors: Caetano Gerardo , Pose Nicolás
Published: February 2024

Este artículo tiene como objetivo analizar el persistente reclamo de Uruguay de flexibilizar la disposición de Mercosur para negociar acuerdos de comercio preferencial (ACP) con terceros países de forma conjunta, con miras a identificar: (1) los factores que han impulsado este planteo; y (2) los límites que ha encontrado. El argumento principal propuesto es que más allá de las coyunturas políticas, tanto los impulsos como los límites responden a combinaciones de factores económicos y políticos más bien estructurales. Por ende, en ausencia de cambios en las posiciones de sus socios del bloque, que por cierto Uruguay no controla, se constata una tendencia hacia el statu quo. Para sostener el argumento, a nivel empírico se analiza en primer lugar la evolución histórica de Mercosur y sus relaciones externas. Y, en segundo lugar, se profundiza en la coyuntura actual, signada por los esfuerzos del gobierno uruguayo de firmar un ACP bilateral con su principal socio comercial, China.
Application of a multivariate optimization strategy to validate an RP-HPLC analytical method for determining hydroxychloroquine sulphate in pharmaceutical products and in forced degradation studies

Published: February 2024

In this study, a multivariate optimization strategy was used to develop and validate a simple, rapid, accurate, cost-effective, and stability-indicative RP-HPLC analytical method for quantifying hydroxychloroquine sulphate (HCQ) in coated tablets. The validation conditions involved isocratic elution mode, using a mixture of buffer solution at pH 2.2 and methanol (74:26, v/v) as the mobile phase, an Agilent® reverse phase column, model Zorbax Eclipse Plus C18 (250 cm × 4.6 mm × 5 μm), a flow rate of 1.3 mL min−1, column temperature 40 °C and detection at 343 nm. The method showed linearity in the range of 4–44 μg mL−1, with a correlation coefficient (R) of 0.9998. Recovery obtained average values of between 99.71 and 100.84% and precision with average RSD values of <2%. The robustness demonstrated by assessing the effect of seven variables (pH of the mobile phase buffer; percentage of methanol; filter brand; mobile phase flow rate; wavelength; column temperature and sample agitation time), with effect values for each variable lower than the calculated value of s√2 (1.43), showed that none of these factors had a significant influence on the analytical response. The method was applied to samples of the reference medicine Plaquinol® 400 mg and similar Reuquinol 400 mg, nomenclature established by the National Health Surveillance Agency (Anvisa), law no. 978 of 10 February 1999, purchased from local pharmacies. Results showed advantages and benefits in relation to the official method and those reported in the literature. The application of the multivariate strategy, the choice of methanol, in a lower proportion in the organic phase, due to its low toxicity, economy and easier availability compared to acetonitrile, and the other organic solvents used was a promising and important alternative for the analytical method. Furthermore, the use of reversed stationary phase, common in quality control laboratories, provided an analyte retention time of 4.595 min, demonstrating good performance and speed in routine analyses.
