A Further Insight into Extraction Procedures Suitable for Separation of Gold Nanoparticles from Environmental Waters
Authors: Hagarová Ingrid , Nemček Lucia
Published: March 2023

Gold nanoparticles (AuNP) are being utilized in an ever-expanding number of applications ranging from scientific research to industrial processes. Increasing nanoparticle emissions in the environment have become of public and academic concern. Since the effects of AuNP on human health are not fully understood, the accumulation of reliable and detailed data is critical for the assessment of their potential risk of harm to humanity. Even their concentrations in natural and engineered water systems do not belong to commonly published data. To obtain such information, the environmental chemists use various sophisticated analytical methods that are often very expensive. Therefore, this paper aims to challenge the analytical potential and advantages of cheaper and equally reliable alternatives that couple the well-established extraction procedures with common spectrometric methods to quantify the ultratrace concentrations of AuNP in complex aqueous matrices. Both types of extraction procedures, solvent extractions as well as sorbent extractions, are discussed in the text. A detailed inspection of different types of interactions that are responsible for the ability to selectively separate AuNP from mixtures containing various ionic species, gold ions, other metallic nanoparticles, and dissolved organic matter can be found in this overview. The examples of the tolerance limits reported for several coexisting components of interest are also given. Practical applications of the extraction procedures, summarized in this article, were demonstrated in analysis of actual environmental matrices, such as tap, river, lake, brook, mineral, and sea waters.
Jasmonates, Their Biosynthesis, Metabolism and Signalling Pathway in Plant Organisms
Authors: Mergová Michaela , Balažová Andrea , Obložinský Marek , Holková Ivana , Mučaji Pavel , Bittner Fialová Silvia
Published: March 2023

Jasmonates, derivatives of jasmonic acid, are lipid-derived oxylipins with cyclopentanone ring, produced as a result of dioxygenation mediated by lipoxygenases. The biosynthesis of jasmonic acid is catalysed by a series of different enzymes, starting from lipoxygenase, allene oxide synthase, allene oxide cyclase and 12-oxophytodienoic acid reductase to the final three rounds of β-oxidation. Consequently, a few metabolites known as jasmonates are formed from the resulting jasmonic acid. Some of these metabolites are active and able to work on the jasmonate receptor and thus start the jasmonate signalling pathway. Products of gene expression resulting from this pathway have a great significance in plant growth, development, reproduction, senescence and also in defence and adaptation to various adverse environmental conditions.
Use of Somatic Coliphages in Biosensoring of Hygiene Safety of Recycled Wastewater
Authors: Zuzáková Jana , Janák David , Vobecká Eliška , Říhová Ambrožová Jana
Published: March 2023

Outflows from secondary stages of conventional mechanical-biological wastewater treatment plants (WWTPs) still contain significant concentrations of faecal pollution indicators suggesting the potential presence of pathogenic organisms. The decrease in the concentration of somatic coliphages and bacterial indicators of faecal pollution during the technological stages (coagulation, sand filtration, membrane ultrafiltration, sorption on granular activated carbon, disinfection, accumulation) of a semi-operational plant designed for multi-stage tertiary treatment or rather recycling of treated wastewater was monitored and discussed. During the tertiary treatment, faecal bacteria indicators were better removed than somatic coliphages, hence the inclusion of somatic indicators among faecal pollution indicators in water quality control for reuse is entirely appropriate. Subsequent tertiary treatment, including disinfection, is essential for safe reuse of treated water.

Authors: Shnyakin Pavel , Dubovoy Andrey
Published: March 2023

The article describes a clinical case of a dissection aneurysm of the basilar artery in a SARS-COV-2 patient. The patient was treated in the hospital for infectious diseases due to bilateral poly-segmental pneumonia complicating a COVID-19 infection. A focal neurological deficit suddenly appeared and rapidly progressed, including paresis of the abducens nerve, bulbar disorders, and a right-sided hemiparesis. During the course of treatment, the patient underwent CT and CT angiography of the cerebral arteries several times. During the first examination, no pathology of the cerebral vessels was discovered. During the examination 10 days later, a fusiform aneurysm of the basilar artery trunk with a daughter sac was detected. Its rupture led to massive subarachnoid hemorrhage and an unfavorable outcome. The occurrence of primary symptoms in this patient could be due to a violation of the blood flow in the short branches of the basilar trunk in the area of the dissection.

Published: March 2023

Blockchain is a peer-to-peer distributed ledger technology, nowadays widely used and a hot topic in the industries. A Smart Contract is a virtual contract based on Blockchain technology which executes and operates between two parties (especially a buyer and a dealer) when a certain condition of the contract is met. The objective of this research is to present a decentralized transaction system based on Blockchain technology implemented using Smart Contract. Blockchain based cryptocurrencies are an evidence for a secure implementation of any currency-based centralized systems put forth in use in a decentralized way. Current transaction systems and payment gateways are centralized systems that need monitoring and verification from a central agency like a bank or a third party organization which are not completely automated as some of the processes are human controlled. Also deposition and withdrawal of money sometimes take a long procedural time. Still these systems are neither completely error free nor secure and time to time certain issues may arise. Even nowadays some payment methods charges transaction fee which is like paying for the money you are paying for. In this research paper we are proposing an automated Ethereum blockchain technology based transactionsystem which will eliminate the bank and third party verification.Each block of the Ethereum blockchain in the system will store the transaction details also linked with all the previous transaction details in the form of a chain. A Smart Contract is used to define the terms and conditions of the transaction which include account creation, ether deposition and withdrawal. This system enables users to carry out transaction without any fraud and losses from anywhere around the globe within split seconds.

The article discusses prescription additives and traces of impurities in the alloy of an assemblage of horse harness and chariot equipment of the Cimmerian period from a barrow near the village of L’govskoe in the North-East Crimea. X-ray fluorescence analysis and inductively coupled plasma mass spectrometry were applied in the study. It was determined that certain alloys were used for casting objects of different functional purposes. So, all cheekpieces were cast from tin-lead bronze without arsenic, and gnawed cheekpieces — on the contrary, from arsenic or tin-arsenic bronze. Arrows in most cases are cast from Cu-Sn-Pb-As-Sb multicomponent alloy. In terms of types, the morphology of objects and metallurgical groups of alloys used, the Cimmerian assemblage fully fits into the general picture presented by researchers for the North Caucasus, the Dnieper, and the lower Don region.
Clothing Assemblage in the Burial Rituals of the Early Iron Age Population of the Upper Ob River Region
Authors:   Altai State Pedagogical University, Golovchenko Nikolai
Published: March 2023

The article characterizes the clothing assemblage in the burial rituals of the Early Iron Age population of the Upper Ob River region. The work draws from the materials found on the Bolsherechenskaya sites of the 8th (7th) — 3rd (2nd) centuries BC. Using this archaeological material, the author examines the event-driven sacralized actions with items of clothing at the stage preceding the burial, and directly during its implementation. The complex of these actions is subdivided into actions associated with symbolic damage to things; actions associated with a change in the symbolic status of things and actions that mark the high symbolic status of things. The clothing assemblage, revealed during the study of the burial, is differentiated into truly aesthetic and symbolically significant things. Whole things, as a rule, related to objects of art, are found in characteristic places of their lifetime use. Things with a symbolic status changed during the funerary rite are recorded in an unusual topographic context. Event sacralization can be viewed as an adaptive strategy for integrating things and ideas into the funerary practice of a multicultural community, consisting of certain ethno-territorial groups “with a consanguineous or neighboring type of community”.

Science and Engineering Education as an Anchor in the Midst of a Changing World: The Case of Covid-19
Authors: Lis-Hacohen Ronit , Binah-Pollak Avital , Hazzan Orit
Published: March 2023

The discourse on science and engineering education focuses on ways of preparing students, as future employees, and global citizens. While this discourse deals with the purposes and characteristics of engineering education, it tends to neglect the students’ perspectives.

The purpose of this study was to provide insights into the perspectives of undergraduate science and engineering students with respect to six factors, during the Covid-19 pandemic: end-of-semester exams, financial situation, social life, extension of study duration, the future of the labor market, and how the world will look. A comprehensive questionnaire was distributed to all undergraduate students in a research science and engineering university in two consecutive academic years. Descriptive statistics and content analysis were applied.

Our findings show that science and engineering students were mostly concerned about their end-of-semester exams. Their social life was the only factor that changed between the two periods in terms of the percentage of students who were concerned with it. As for the other factors, the percentage of students who were concerned about them remained comparatively the same in both academic years. The findings highlight the confidence students had during the pandemic, and demonstrate the resilience of science and engineering, especially in times of volatility.

Sectoral and Regional Volatility Connectedness: The Case of CDS Spreads and Equities
Authors: Manicaro Christian
Published: March 2023

This study analyses volatility connectedness at sectoral and regional level within and across the US, UK, EU and Japanese regions between the CDS and equity markets. Analysis is made on 32 sectors and 70 sub-sectors within the regions under study with each having 2,479 observations, covering the period between 2008 until June 2017. The sample is divided between crisis and after-crisis period and the novel connectedness index by Diebold-Yilmaz (2014) is proposed. The domestic and regional analysis show that connectedness between the two asset classes is in general higher during the crisis period. Although the static Gaussian results for the regional analysis show low levels of connectedness across the board, the dynamic analysis show significant connectedness levels, with levels being predominantly higher during the crisis period, signifying contagion effects also at regional level between the two asset classes. When considering the dynamic volatility connectedness between the two asset classes, equity is the asset class which transmits volatility the most. In the US and EU connectedness between the two asset classes in most sectors is predominantly large during disturbed periods, particularly the 2009 crisis and the EU sovereign crisis.
Error Estimates for Doubly-Generalized Tikhonov-Phillips Regularization
Authors: Carrió M. J. , Mazzieri G. L. , Temperini K. G.
Published: March 2023

In this work, error estimates are presented for the case in which the regularized solution is obtained by minimizing doubly-generalized Tikhonov-Phillips functionals. The first result is based mainly on an assumption given by a source condition. It is proved that it is possible to replace this assumption by a variational inequality, obtaining analogous result of the error estimate. Finally, relationships are established between the optimality condition associated with the problem, the source condition and the variational inequality. On the other hand, it is known that, in certain cases, the use of two or more penalizing terms is useful. For this reason, generalizations of the results of error estimates are presented for cases in which the regularized solution is a minimizer of doubly-generalized Tikhonov-Phillips functionals with multiple penalizers.
EPIGUI: Graphical User Interface for Simulating Epidemics on Networks
Authors: Pinto E. R. , Nepomuceno E. G. , Kusak J. , Campanharo A. S. L. O.
Published: March 2023

This paper presents a graphical interface called EPIGUI, which allows the study of the dynamics of an infectious disease spread using compartmental models in combination with complex networks. This interface aims at considering stochastic factors that govern the evolution of an infection in a network. Moreover, it provides simple tools to create networks of agents and to define the epidemiological parameters of outbreaks. There are six common infectious disease models (SI, SIS, SIR, SIRS, SEIR, and SEIRS) or a user can provide another model, combining compartments. Moreover, in the simulations the user can either include a synthetic network generated according to a network model (random, small-world, scale-free, modular, or hierarchical) or a real network. This approach can help understand the paths followed by outbreaks in a given community and design new strategies to prevent and to control them.
Sufficient Conditions for Existence of the LU Factorization of Toeplitz Symmetric Tridiagonal Matrices
Authors: Almeida C. G. , Remigio S. A. E.
Published: March 2023

The characterization of inverses of symmetric tridiagonal and block tridiagonal matrices and the development of algorithms for finding the inverse of any general non-singular tridiagonal matrix are subjects that have been studied by many authors. The results of these research usually depend on the existence of the LU factorization of a non-sigular matrix A, such that A = LU. Besides, the conditions that ensure the nonsingularity of A and its LU factorization are not promptly obtained. Then, we are going to present in this work two extremely simple sufficient conditions for existence of the LU factorization of a Toeplitz symmetric tridiagonal matrix A. We take into consideration the roots of the modified Chebyshev polynomial, and we also present an analysis based on the parameters of the Crout’s method.

Authors: AL-Sabbah Shrook , Inad Maryam , Ghazi Marwa
Published: March 2023

Agricultural experiments play a major role for workers in the agricultural field in terms of experimentation and analysis in order to reach the most important factors affecting plant productivity and agriculture, and play a fundamental role in the economic sector. However, some countries suffer from a shortage of these crops due to the exposure of some cultivated areas to a range of environmental factors such as drought and salinity, which reached about 33% of the cultivated land, as these environmental phenomena affect the various stages of plant growth and development and its various physiological functions with their physical and chemical properties. In recent years, the harmful effects of saline environments in weak lands have been overcome by some means, such as the use of chemical growth regulators by soaking the seeds before planting or spraying plants. The study aimed to find out the effect of green tea extract on cucumber production by planting cucumber seeds in four different time periods (0, 6, 12, and 24 hours) in different salt concentrations (0, 1.5, 2.5, 3.5 dsm / m) and in three different concentrations (0.1, 0.01, 0.001) from green tea solution before germination. The experiment was conducted according to a split-plots design (4 *4*3* 3), after implementing the Normal Distribution test for the data, and then implementing the Variance Analysis and calculate the effects of the factors. The results of the study showed that green tea extract had a significant effect on the length of the Vegetative total. The best level was the first level (0.1), We note that Factor (B), the time factor, which is the duration of plant infusion in green tea, has a significant effect on response rates, and the best duration gave a response is the (12) hours period, and Factor (C), which is the salt concentration ratios in the plant, has a significant effect on the response rates. The best response level is the second concentration (1.5), and the interaction between them was significant and influencing to the plant. Also, the double and the triple interactions are significant and not independent in their effect on the response rates represented by the length of the Vegetative total.
“Will it Catch Their Attention?” – Evaluating Situated and Peripheral Displays in a Personal Context
Authors: Güldenpfennig Florian , Ganhör Roman , Fitzpatrick Geraldine
Published: March 2023

Connecting people with technology is an important challenge in HCI and ubiquitous computing. Digital photo frames are a popular class of private situated displays particularly aimed at this purpose. However, their evaluation can be challenging as a significant amount of interaction takes place by looking at the device, i.e., without direct user input. In addition, a photo display can effect people’s perception, without it being at the centre of focussed attention. For tracking use without explicit input and getting a sense of the users’ peripheral perception – and hence the users’ potential awareness of situated displays – we therefore propose a lightweight, unobtrusive and affordable method named Trackaware, drawing on advances in camera hardware and software. We are particularly interested in how researchers and study participants engage with this method and what insights they can obtain. We studied Trackaware involving 61 participants, and our findings suggest that Trackaware can be a strong method for complementing existing evaluation techniques, e.g., in a data triangulation strategy. It should be useful for investigating digital photo frames and other visual peripheral displays, particularly in personal contexts.
Troubling Futures: Can Participatory Design Research provide a Constitutive Anthropology for the 21st Century?
Authors: Light Ann
Published: March 2023

This paper argues there is value in considering participatory design as a form of anthropology at a time when we recognise that we need not only to understand cultures but to change them towards sustainable living. Holding up the democratically-oriented practices of some participatory design research to definitions of anthropology allows the essay to explore the role of intervention in social process. And, challenging definitional boundaries, it examines design as a participatory tool for cultural change, creating and interrogating futures (and the idea of futures). In analysing how designing moves towards change in the world, the paper brings together design research and anthropological concepts to help us better understand and operationalise our interventions and pursue them in a fair and sustainable manner.

Aquest article té com a objectiu mostrar com una cançó de gesta (en aquest cas Raoul de Cambrai) situada en època carolíngia pot reflectir la reacció de l’aristocràcia feudal de finals del segle xii enfront d’un poder reial en fase d’expansió. Comencem mostrant que les cançons de gesta es percebien, al seu temps, com a relats de caire històric. Ens referim també a la considerable difusió d’aquests poemes, que els permetria constituir-se en una mena de contrarelat respecte a la història oficial vehiculada per les cròniques. Comentem, després, quina era la visió de la figura reial als diferents cicles de les cançons de gesta i passem a examinar el rerefons històric de la cançó de Raoul de Cambrai. Tot seguit, analitzem els lligams entre la cançó de gesta i els vincles feudovassallàtics. Precisem quina és la relació entre Raoul de Cambrai i l’època de la seva escriptura, i tractem dues qüestions importants: el principi de solidaritat basat en el llinatge i la percepció del feu com a propietat hereditària. Aquest article està redactat amb un objectiu didàctic: servir de text de suport per a la redacció de treballs de curs en el marc d’una assignatura de literatura medieval francesa de grau.

Introduction
Authors: Suso López Javier
Published: March 2023

L'expression « grammaire de la langue parlée » relève de l’incompréhension, ou tout au moins elle est inhabituelle, proche d’un oxymoron : si la grammaire est, tout d’abord ou étymologiquement, l’étude des lettres (grammata), comment pourrait-il exister une grammaire de la langue parlée (de l’oralité), qui est composé de sons ? C’est ainsi qu’elle évoque chez les linguistes ou les didacticiens ce qui touche à la norme orale d’une langue : elle contiendrait une « orthoépie » (qui règle la prononciation correcte), une « grammaire de l’intonation » (cf. Morel & Danon-Boileau, 1998), ainsi qu’une proposition d’un modèle standardisé quant au système accentuel et rythmique reposant sur le français de Paris)… Somme toute, ce que comprend la « phonétique » en tant que discipline (scientifique et scolaire) : pourquoi alors compliquer les choses et se risquer à utiliser une expression ambiguë et problématique ? Voilà des questions parmi d'autres auxquelles le présent numéro de la revue Langue(s) & Parole entend répondre.
statut de l'oralité dans l'enseignement-apprentissage des langues
Authors: Murillo Puyal Julio
Published: March 2023

Alors que nous célébrons le centenaire de la publication du Cours de Linguistique Générale, le principe selon lequel les langues « ont une manifestation normale et primaire qui est phonique » a acquis valeur axiomatique en Linguistique. Vu les relations traditionnellement ancillaires entre la Didactique des Langues et la Linguistique, il y aurait lieu de penser que ce même principe a été adopté dans l’enseignement-apprentissage des langues et que la didactique de l’oralité ne fait plus problème. Le traitement réservé à la matière phonique dans l’enseignement des langues étrangères, et la notion même de langue orale sur laquelle se fondent ces approches révèlent cependant que, dans le meilleur des cas, l’oralité est réduite et circonscrite au flux phonique et/ou à l’activité des organes du tractus phonatoire. Or, d’innombrables phénomènes de parole (variabilité phonique, rythme, métaphonie, macromotricité, modalités énonciatives, proprioception, etc.) témoignent de ce que les manifestations phoniques sont générées dans le processus du dire bien avant qu’elles soient produites dans le tractus phonatoire, et avant que se structure le flux phonique en phonèmes : le processus de parole s’amorce dans une phase prélinguistique et est régi par la « Logique du vivant ». C’est dans cette phase d’émergence du langage que l’intervention pédagogique a sa raison d’être. Les valeurs de la langue parlée permettent de caractériser ce processus en vue d’établir des procédures didactiques qui ne peuvent être efficaces qu’à cette étape. Le statut de l’oralité étant ainsi défini, l’écriture – conçue comme représentation symbolique et non comme image analogique –, et bien entendu à condition qu’on n’y ait recours que pour compléter le processus de structuration et mémorisation de la matière phonique et non pour amorcer ledit processus, constitue un moyen « dont on ne peut se passer » (Saussure dixit) pour représenter la parole et l’engrammer d’une manière efficiente.
Augmenter le nombre de plurilingues en Union européenne en créant des itinéraires différents pour y parvenir
Authors: Braun Alain
Published: March 2023

La problématique du plurilinguisme est centrale en Union européenne. Pourtant les systèmes d’enseignement ont peu évolué pour s’adapter aux besoins. Apparaissent toutefois ici et là des dispositifs plus originaux pour répondre aux attentes plurilingues ET aux profils des apprenants. Cet article vise à en faire un état en Belgique en accordant une attention particulière à la filière immersive et en tentant de lister les avantages et inconvénients de chacun d’eux.

Explorer des oeuvres de francophonie périphérique (Belgique francophone) pour amplifier l'expérience interculturelle d'apprenants en Erasmus
Authors: Castadot Élisabeth
Published: March 2023

En tant que professeur de français langue étrangère pour des étudiants Erasmus qui viennent étudier dans une université francophone hors de France, l’on peut s’interroger sur la pertinence d’enseigner les variations linguistiques et les références culturelles et littéraires propres à cet espace francophone, ou d’abord et avant tout des références et œuvres « franco-centrées ». L’appropriation deréférences culturelles et de spécificités francophones « locales » présente cependant un double intérêt. D’une part, les apprenants y sont, par immersion, confrontés ; connaitre ces particularités ne peut que les aider à oser pratiquer réellement leur français avec des natifs, en dehors de la classe. D’autre part, la découverte d’œuvres ou de références d’une communauté francophone « périphérique » (Klinkenberg, 2010) ouvre, pour ces étudiants internationaux, une voie vers la réflexivité sur l’expérience de décentrement qu’ils vivent (Anquetil, 2006 ; Meunier, 2015), ainsi que sur le développement de compétences interrelationnelles que le séjour Erasmus peut leur permettre de développer.

À la suite de cette réflexion, il s’agira de présenter, de façon très concrète, quelques exemples de tâches et d’œuvres présentées à un groupe d’étudiants en séjour Erasmus en Belgique francophone, afin d’entamer avec eux cette démarche de réflexivité à partir de productions culturelles et littéraires de créateurs et créatrices belges francophones. L’on s’interrogera aussi sur la « déconstruction » de certaines attitudes puristes ou de stéréotypie vis-à-vis du français ou des Francophones, initiée grâce à la découverte de la pluralité lexicale du français de Belgique et de diverses œuvres littéraires et artistiques de cette aire « périphérique ».

Laicidad y enseñanza
littérature peut tout!
Authors: De Carlo Maddalena
Published: March 2023

Dans cette contribution, nous nous interrogeons sur le rôle que l’enseignement de la littérature dans les contextes scolaires et universitaires peut jouer pour former des individus et des citoyens capables non seulement d’apprécier la valeur esthétique des productions littéraires de tout temps et de toutes aires géographiques et culturelles, mais aussi de réfléchir sur la condition humaine et sur l’universalité de certaines expériences de vie des êtres humains, en dépit de la grande variété de leurs modalités d’expression. Pour atteindre ce but, nous avons choisi nous pencher dans cette contribution sur des récits de vie qui racontent l’expérience de la migration, de l’exil, du deuil et du sens de perte qu’ils engendrent, en tant que lieu de réflexion privilégié sur la nature paradoxale de toute expérience humaine se situant entre appartenance et étrangeté.
Élaboration d'un nouveau modèle de la langue et lexicographie
Authors: Le Pesant Denis
Published: March 2023

Dans notre article, nous traçons les grandes lignes du modèle de la langue initié par Zellig S. Harris et complété par Maurice Gross. Ce dernier définit ce modèle (ou théorie) comme étant l’association de la grammaire (en tant que système de règles) et du lexique (en tant que définition extensionnelle du système de règles), d’où la notion de lexique-grammaire. La question est pour nous de savoir quel est le type de lexicographie qui convient au modèle du lexique-grammaire : nous montrons que dans ce cadre, les dictionnaires sont nécessairement des bases de données informatisées et que la lexicographie est par conséquent plus qu’une méthodologie de recherche ; elle est aussi la réalisation la plus aboutie du modèle de la langue. Nous nous intéressons aux dictionnaires informatisés de Maurice Gross, de Gaston Gross et de Jean Dubois & Françoise Dubois-Charlier, que nous présentons comme des jalons importants dans l’entreprise de modélisation de la langue française.
Condorcet en España: la instrucción pública, los derechos de las mujeres
Authors: Boixareu Mercè
Published: March 2023

La obra de Condorcet en España es conocida ya por sus contemporáneos, entre ellos Jovellanos, e inspira a los ilustrados españoles, especialmente en lo referente a informes y propuestas sobre políticas educativas. Su influencia y valoración durante los siglos XIX y XX depende de las ideologías, de las políticas imperantes y de las de los comentaristas y críticos que se ocupan de su obra. A partir de la transición democrática y especialmente con motivo del bicentenario de la Revolución francesa (1989), el interés por las ideas de este adalid de la educación universal (gratuidad, coeducación, formación a lo largo de la vida) y de la laicidad, es creciente en nuestro país.Si bien sus obras sobre la instrucción pública son las más conocidas y comentadas, no faltan estudiosos que hayan puesto su atención en los contenidos jurídicos y en las reflexiones filosóficas de su obra histórica. Se han estudiado también sus escritos en defensa de los derechos democráticos de las mujeres, pero creemos que, en la historia del feminismo, esta aportación no ha sido suficientemente valorada.
