Authors: Suerungruang Suparerk , Sornlorm Kittipong , Laohasiriwong Wongsa , Mahato Roshan Kumar
Published: August 2023

Under-5 mortality rate (U5MR) is a key indicator of child health and overall development. In Thailand, despite significant steps made in child health, disparities in U5MR persist across different provinces. We examined various socio-economic variables, health service availability and environmental factors impacting U5MR in Thailand to model their influences through spatial analysis. Global and Local Moran’s I statistics for spatial autocorrelation of U5MR and its related factors were used on secondary data from the Ministry of Public Health, National Centers for Environmental Information, National Statistical Office, and the Office of the National Economic and Social Development Council in Thailand. The relationships between U5MR and these factors were modelled using ordinary least squares (OLS) estimation, spatial lag model (SLM) and spatial error model (SEM). There were significant spatial disparities in U5MR across Thailand. Factors such as low birth weight, unemployment rate, and proportion of land use for agricultural purposes exhibited significant positive spatial autocorrelation, directly influencing U5MR, while average years of education, community organizations, number of beds for inpatients per 1,000 population, and exclusive breastfeeding practices acted as protective factors against U5MR (R2 of SEM = 0.588).The findings underscore the need for comprehensive, multi-sectoral strategies to address the U5MR disparities in Thailand. Policy interventions should consider improving socioeconomic conditions, healthcare quality, health accessibility, and environmental health in high U5M areas. Overall, this study provides valuable insights into the spatial distribution of U5MR and its associated factors, which highlights the need for tailored and localized health policies and interventions.

Authors: Haghighat Shila , Khosravi Maryam , Saadatnia Mohammad , Hashemijaazi Maryamsadat
Published: August 2023

Background:

Post-stroke hemiplegic shoulder pain (HSP) is a common complication leading to significant activity limitation. Some approaches have been recommended for the management of HSP, and most of them have various adverse effects, while none were established to be effective. This study aimed to evaluate the effect of minimally invasive extracorporeal shockwave therapy (ESWT) on patients with HSP pain management.

Materials and Methods:

Using a single-blind, randomized clinical trial, 43 patients with HSP were randomly assigned to complete three focus ESWT sessions once a week and additional five radial ESWT sessions twice a week. Patients in the control arm received zero energy ESWT. Visual analog scale, passive range of motion (ROM), Fugl-Meyer upper extremity assessment (FMA-UE), and shoulder pain and disability scale (SPADI) were measured at baseline, at the end of the interventions, and within four and eight weeks' intervals to evaluate the pain, function, and ROM in the affected shoulder.

Result:

Both groups showed an improvement in pain scores on the fourth and eighth weeks visits (P-value <0.001). Intervention with ESWT could effectively lead to a less severe pain score compared to the control group (P-value <0.001). In the intervention group, the ROM improved in both passive abduction and forward flexion (P-value <0.05), but no significant change was observed in the control group (P-value >0.05). FMA-UE and SPADI did not differ significantly between groups.

Conclusion:

Based on the findings of this study, the combination of rESWT and focused ESWT can efficiently improve stroke-induced HSP.

Published: August 2023

Background:

Spinal cord injury (SCI) is the second cause of complications and disability after brain injury. Although primary prevention is the best strategy, obtaining the necessary knowledge about the patient's condition and follow-up treatment can lead to the use of safety measures and appropriate healthcare planning. This is the basis of this study with the aim of a two-year follow-up of patients with traumatic SCI (TSCI) who underwent surgery.

Materials and Methods:

This study was a descriptive and analytical type that examined 79 patients with TSCI who had undergone surgery two years ago. The data were collected by a standard questionnaire and analyzed in Statistical Package for the Social Sciences (SPSS) version 24 software.

Results:

Among the patients in our study, 39.2% of them had the initial C American Spinal Injury Association (ASIA) score followed by patients with grade D (31.6%), grade A (15.2%), and grade E (14%), respectively, and also, a most common type of vertebral column injuries is burst fractures with a prevalence of 62%, followed by fracture–dislocation injury (25.3%) and compressed fracture (12.7%). Regarding the improvement of patients according to ASIA grade, the highest percentage of improvement is seen in grad grades D (84% and 77%), and grade A patients have improved to grade B by about 33.3%. In the study conducted, 5% of patients died during 24 months of follow-up, which means 75% of the deceased patients were grade A patients at the time of admission.

Conclusion:

As mentioned, the most important predictor of the patient's prognosis is the patient's initial condition.

Background/Purpose:

Periodontitis is an inflammatory disease due to microbial plaque that causes bone loss and tooth mobility. Its prevention and treatment include microbial plaque control, which is presently attained by both mechanical and chemical methods. This study aimed to investigate the antimicrobial effect of the hydroalcoholic extract of Elettaria cardamomum on Aggregatibacter actinomycetemcomitans (Aa) which is one of the most important bacterium of periodontitis.

Materials and Methods:

The hydroalcoholic extract of E. cardamomum was obtained by the maceration method in the Traditional Medicine of Tehran University Medical Sciences Department. The Aa (Jp2nov99) bacterial strain was cultured. The inhibition zone diameter of Aa was measured by agar-well diffusion methods for concentrations of 25% and 50% of E. cardamomum. The mean group’s inhibition zone diameter was analyzed using the SPSS software. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of this extract were determined by the broth microdilution method. Chlorhexidine 0.2% was used as a control and the results were compared.

Results:

The inhibition zone diameter of this extract was measured at different concentrations. The highest and the lowest diameters of 20.5 mm and 20.0 mm were associated with 50% and 25% concentrations, respectively. The MIC and MBC values for this bacterium were at 0.0039 mg/ml and 0.0039 mg/ml as compared with 0.00065 mg/ml and 0.00098 mg/ml for 0.2% of chlorhexidine.

Conclusion:

The hydroalcoholic extract of E. cardamomum has an antibacterial effect on the Aa bacterium and may be used in mouthwash as an alternative to chlorhexidine.

Abstract

Aims and Objectives:

The aim of this in vitro study was to evaluate the remineralization effect of calcium glycerophosphate (CaGP) in fluoride mouth rinse on permanent enamel eroded by a soft drink.

Materials and Methods:

Forty sound permanent premolars were embedded in self-curing acrylic resin and immersed in Coca-Cola to create erosive lesions. The teeth were divided into four groups (n = 10): Group I artificial saliva; Group II sodium fluoride; Group III sodium fluoride + sodium monofluorophosphate; and Group IV sodium monofluorophosphate + CaGP. The specimens in the assigned groups underwent pH cycling for ten days. The baseline, after erosion, and after remineralization surface microhardness (SMH) values were determined. The data were analyzed by one-way analysis of variance (ANOVA). The mean SMH value between groups and one-way repeated measures ANOVA for the mean SMH value within each group and Bonferroni’s for multiple comparisons at a 95% confidence level were determined. The average SMH was used and calculated as the percentage recovery of SMH.

Results:

After being eroded by the cola soft drink, the mean SMH values in all groups were significantly decreased. After remineralization, Group I had the lowest %SMHR. The %SMHR of Groups II, III, and IV were significantly higher than Group I (P < 0.001). However, there were no significant differences among Groups II, III, and IV (P > 0.05).

Conclusions:

Fluoride mouth rinse with and without CaGP showed similar efficacies in remineralizing eroded permanent enamel.

Published: August 2023

Background: Diabetic ketoacidosis (DKA) is a common endocrine emergency in pediatric patients. Early presentation to health facilities, diagnosis, and good management in the pediatric intensive care unit (PICU) are crucial for better outcomes in children with DKA. Methods: This was a single-center, retrospective cohort study conducted between February 2015 and January 2022. Patients with DKA were divided into two groups according to pandemic status and diabetes diagnosis. Both groups were examined in two subcategories (pandemic status: pre-pandemic vs. pandemic; and diabetes diagnosis status: previously diagnosed vs. newly diagnosed).Results: The study enrolled 59 patients, and their mean age was 11±5 years. Forty (68%) had newly diagnosed type 1 diabetes mellitus (T1DM), and 61% received follow-up in the pre-pandemic period. Blood glucose, blood ketone, potassium, phosphorus, creatinine, and alanine transaminase levels were significantly higher in the new-onset T1DM group compared with the previously diagnosed group (P=0.01, P=0.02, P=0.01, P=0.039, and p=0.001, respectively). In patients with newly diagnosed T1DM, length of PICU stays were longer than in those with previously diagnosed T1DM (28.5±8.9 vs. 17.3±6.7 hours, p<0.005). The pandemic group was compared with pre-pandemic group, there was a statistically significant difference in laboratory parameters of pH, HCO3, and lactate and also Pediatric Risk Of Mortality (PRISM) III score. All patients survived, and there were no neurologic sequelae. Conclusion: Patients admitted during the pandemic period were admitted with more severe DKA and had higher PRISM III scores. During the pandemic period, there was an increase in the incidence of DKA in the participating center compared to that before the pandemic. Although the reason for this is not fully known, it could be public health presentations were not effective during the coronavirus disease 2019 (COVID-19) period.

Published: August 2023

Aujourd’hui, la surcharge informationnelle se fait de plus en plus ressentir. Nous sommes chaque jour un peu plus inondés par la masse informationnelle, ce qui rend la tâche de la prise de décision encore plus difficile dans les organisations. Cet article vise à comprendre comment la capacité d’absorption peut contribuer à gérer la surabondance des informations issues de la veille stratégique. L’objectif est de déterminer et d’analyser la relation entre la veille stratégique et la capacité d’absorption pour gérer la surcharge d’informations, et de contribuer aussi à enrichir les connaissances sur le sujet. Ce travail fut mené auprès de six centres de recherche, dont trois centres canadiens et trois autres algériens. Une étude qualitative a été privilégiée pour comprendre les différents points de vue des répondants. Nos résultats révèlent que, la veille stratégique peut générer une surcharge d’informations, et que la capacité d’absorption des employés a une influence sur cette surabondance. Néanmoins, l’utilisation de la capacité d’absorption comme entonnoir pour filtrer les informations pertinentes ne peut être suffisant.

Published: August 2023

On rice (Oryza sativa L.), more than 70 diseases caused by fungi, bacteria, viruses, and nematodes have been listed. Among them, the  blast disease caused by Magnaporthe oryzae B. Couch (syn. Pyricularia oryzae Cavara) seriously threatens global rice production  worldwide. Effective management strategies such as the use of resistant cultivars and the application of fungicides individually cannot  sustainably contain rice blast disease, because of the emergence of resistance genes and environmental threats. Therefore, applying  bioagents to reduce M. oryzae infections, complete other strategies, and reduce pesticide dependence. The present work was carried out  to evaluate the potential of not only plant rhizosphere-associated fungi in controlling Magnaporthe oryzae but also the effectiveness of  five fungicides in coculture in vitro. Twenty-three biocontrol fungi mainly Trichoderma and Penicillium evaluated on six M. oryzae isolates  were found to reduce pathogen growth in dual culture assay. The results obtained highlighted the good ability of bioagents to inhibit the  growth of M. oryzae by 82.7 to 97% at 7 days after incubation. In addition, the fungicides tested namely Amistar, Horizon, Opu, Spartaktak,  and Signum successfully inhibited the mycelial growth of M. oryzae. The major outcome of our study was evidence that all M.  oryzae isolates were susceptible to the fungicides tested through their concentration (ppm) of 50% (EC50). No pathogen isolate was  hypersensitive or resistant to fungicides with the EC50 average values of 0.24, 0.25, 0.28, 0.33, and 0.38 mg/l respectively for Spartak,  Signum, Horizon, Amistar, and Opus. These good bioagents must be tested on plants in the greenhouse and the best of them could be  used in IPM strategy with the combination of resistant cultivars and a reasoned use of fungicides for blast disease control.
Petrochemistry of Charnockitic Rocks of Awo-Osuntedo Area, southwestern Nigeria
Authors: Adetunji A.
Published: August 2023

The petrochemistry of charnockitic rocks from the Awo-Osuntedo area of southwestern Nigeria were investigated with the objectives of  presenting their petrogenesis and geotectonic setting at the time of their emplacement. The rocks were mainly found within the  migmatitic gneiss country rock and associated pegmatites. They occurred as small intrusive bodies and are composed mainly of  orthopyroxene, clinopyroxene, quartz, biotite, secondary amphibole, plagioclase and alkaline feldspars with a small compositional range between basic and intermediate respectively for Awo and Osuntedo rocks. The small Eu* anomalies (0.9-1.47) with an average of 1.2  combined with elemental signatures indicate that the rocks were derived from an enriched mantle with some crustal contamination and  emplaced in an environment similar to the arc region of tectonic setting. Though, the rocks have dry mineral assemblages, there is no  geochemical evidence to suggest they were derived from melting that was associated with granulite facies metamorphism rather the  small sizes of the plutons and the geochemical signatures particularly high magnesian and calc-alkaline nature are typical of the Caledonian type charnockite formed during delamination of thickened continental crust after collisional orogeny.
Crack branching at low tip speeds: spilling the T
Authors: Eid Elie , Seghir Rian , Réthoré Julien
Published: August 2023

Using the criterion that a crack will extend along the direction of maximum circumferential stress, this paper demonstrates the influence of the coupling between the crack-parallel T-stress and the tip speed on the directional (in)stability of dynamics cracks in brittle materials, i.e., branching, turning, and limiting velocities. The proposed (in)stability criterion evolves within the theory of dynamic fracture: we build on the work of Ramulu and Kobayashi (1983) by introducing a reference distance ahead of the crack-tip to incorporate the contribution of the higher-order terms in the asymptotic solution of the elastic crack-tip fields. The theoretical aspect is first explored, a methodology to numerically (and experimentally) advocate the instability—as a co-action of T-stress and a fast-running crack—is then proposed and validated on Borden et al. (2012)’s branching benchmark. An experimental setup combining Ultra-High-Speed High-Resolution imaging with advanced Digital Image Correlation algorithms and a novel crack-branching inertial impact test enables for never-seen-before quantification of the rich dynamical behaviour of the fracture. This permits the experimental validation of the developed crack (in)stability criterion.

Dlog is Practically as Hard (or Easy) as DH – Solving Dlogs via DH Oracles on EC Standards
Authors: May Alexander , Schneider Carl Richard Theodor
Published: August 2023

Assume that we have a group G of known order q, in which we want to solve discrete logarithms (dlogs). In 1994, Maurer showed how to compute dlogs in G in poly time given a Diffie-Hellman (DH) oracle in G, and an auxiliary elliptic curve ˆÊ (Fq) of smooth order. The problem of Maurer’s reduction of solving dlogs via DH oracles is that no efficient algorithm for constructing such a smooth auxiliary curve is known. Thus, the implications of Maurer’s approach to real-world applications remained widely unclear.In this work, we explicitly construct smooth auxiliary curves for 13 commonly used, standardized elliptic curves of bit-sizes in the range [204, 256], including e.g., NIST P-256, Curve25519, SM2 and GOST R34.10. For all these curves we construct a corresponding cyclic auxiliary curve ˆÊ(Fq), whose order is 39-bit smooth, i.e., its largest factor is of bit-length at most 39 bits.This in turn allows us to compute for all divisors of the order of ˆÊ(Fq) exhaustively a codebook for all discrete logarithms. As a consequence, dlogs on ˆÊ(Fq) can efficiently be computed in a matter of seconds. Our resulting codebook sizes for each auxiliary curve are less than 29 TByte individually, and fit on our hard disk.We also construct auxiliary curves for NIST P-384 and NIST P-521 with a 65-bit and 110-bit smooth order.Further, we provide an efficient implementation of Maurer’s reduction from the dlog computation in G with order q to the dlog computation on its auxiliary curve ˆÊ (Fq). Let us provide a flavor of our results, e.g., when G is the NIST P-256 group, the results for other curves are similar. With the help of our codebook for the auxiliary curve Ê(Fq), and less than 24,000 calls to a DH oracle in G (that we simulate), we can solve discrete logarithms on NIST P-256 in around 30 secs.From a security perspective, our results show that for current elliptic curve standards< the difficulty of solving DH is practically tightly related to the difficulty of computing dlogs. Namely, unless dlogs are easy to compute on these curves G, we provide a very concrete security guarantee that DH in G must also be hard. From a cryptanalytic perspective, our results show a way to efficiently solve discrete logarithms in the presence of a DH oracle.
Exploiting Intermediate Value Leakage in Dilithium: A Template-Based Approach
Authors: Berzati Alexandre , Calle Viera Andersson , Chartouny Maya , Madec Steven , Vergnaud Damien , Vigilant David
Published: August 2023

This paper presents a new profiling side-channel attack on CRYSTALSDilithium, the new NIST primary standard for quantum-safe digital signatures. An open source implementation of CRYSTALS-Dilithium is already available, with constant-time property as a consideration for side-channel resilience. However, this implementation does not protect against attacks that exploit intermediate data leakage. We show how to exploit a new leakage on a vector generated during the signing process, for which the costly protection by masking is still a matter of debate. With a corpus of 700 000 messages, we design a template attack that enables us to efficiently predict whether a given coefficient in one coordinate of this vector is zero or not. By gathering signatures and being able to make the correct predictions for each index, and then using linear algebra methods, this paper demonstrates that one can recover part of the secret key that is sufficient to produce universal forgeries. While our paper deeply discusses the theoretical attack path, it also demonstrates the validity of the assumption regarding the required leakage model from practical experiments with the reference implementation on an ARM Cortex-M4. We need approximately a day to collect enough representatives and one more day to perform the traces acquisition on our target.

Field Programmable Gate Arrays (FPGAs) are used more and more frequently to implement cryptographic systems, which need random number generators (RNGs) to be embedded in the same device. The main challenge related to the implementation of a generator running inside FPGAs is that the physical source of randomness, such as jittered clock generator, is implemented in the configurable logic area, i.e. in the close vicinity of noisy running algorithms, which can have significant impact on generated numbers or even serve to attack the generator. A possible approach to prevent such influence is the use of Phase-Lock Loops (PLLs), which are separated from the re-configurable logic area inside the FPGA chip. In this paper, we propose a new architecture of the PLL-based TRNG including a method to avoid correlation in the output through control of timing in the sampling process, as well as new embedded tests based on the enhanced stochastic model. We also propose a workflow to help find the best parameters, such as output bitrate and entropy rate. We show that bitrates of around 400 kb/s or more can be achieved, while guaranteeing min-entropy rates per bit higher than 0.98 as required by the latest security standards.
La mise en scène en els drames medievals catalans
Authors: Massip Francesc
Published: August 2023

The study of religious drama in the Middle Ages, which due to its character as a communal drama has occupied a place within the European avant-garde like perhaps no other epoch before, shows us a variety of spectacular visual, auditory and even olfactory possibilities of representation, which both require a highly developed technique, as well as an admirable aesthetic maturity and show us ways in which the rift between the actor and the spectator created by the proscenium stage can be eliminated. This can be exemplified by the only play in Europe that has been performed in an uninterrupted tradition since the Middle Ages (every August 15th) to the present day in the southern Valencian town of Elx near Alacant: The Misteri d'Elx is total theatre, shaped by a combination of excellent music and daring, perfect staging.
Connotacions i derivacions sociolingüístiques dels conceptes de "llengua" i "dialecte"
Authors: Martí i Castell Joan
Published: August 2023

The article provides an overview of the – heavily ideologically charged – use of the terms "language" (llengua) and "dialect", the possibilities of their scientific justification, and the political implications and consequences of this distinction, especially with regard to the situation of Catalan. We are reminded that from a strictly linguistic (structural) point of view there is no essential difference between "languages" and "dialects" (both contain the Saussureian conceptual dichotomy of abstract "value" or rule system (langue) on the one hand, concretization in the parole on the other). However, in the historical processes of nation building, in connection with domestic and international hegemony efforts and their legitimation, different discriminating status attributions and evaluations at the expense of the minorized language varieties (= "dialects") prevail. The negative effects of such conceptual hierarchies are mainly presented in the controversies about Mallorcan and Valencian, but without going into detail about the detailed discussion of Catalan sociolinguistics.
Kritische Würdigung des neuen katalanischen etymologischen Wörterbuches von Joan Coromines
Authors: Baldinger Kurt
Published: August 2023

Between 1980 and 1988, eight of the nine announced volumes of Joan Coromines' Etymological and Complementary Dictionary of the Catalan Language (Diccionari etimològic i complementari de la llengua catalana) appeared. He had previously published two editions of the Spanish etymological dictionary (the last volume from the second edition is still missing). This is undoubtedly a gigantic work, internationally recognized by Romanists. But the controversial nature of the author and his intolerance, leading to slander, have also been criticized. Colleagues who have dared to make justified criticisms of some etymologies indicated by Coromines have, as a result, been badly criticized.
Les imatges del mes d'abril i de la mar a la fraseologia catalana i alemanya: un estudi comparatiu de les característiques nacionals i internacionals
Authors: Soler i Marcet Maria-Lourdes
Published: August 2023

Attempts to show national traits in phraseology have not hitherto been very convincing. However, it cannot be denied that they do reflect the peculiarities of a specific culture. From the comparison of Catalan and German proverbs and idioms for the pictures of the month of April on the one hand and for the sea and the ocean on the other hand, the following differences can be determined: For April, the seasonally more advanced stage of plant and animal development in Catalonia finds its resonance in the phraseology. The German proverbs and proverbial sayings emphasize the instability of the month (e.g. with regard to weather conditions), in contrast to the Catalan ones, which emphasize more its insidiousness. As for the sea, for the Catalans it is a source of wealth, honour and health. These images are missing in German, where, on the other hand, seashores and borders play a major role. The German phrasemes for both April and the sea often have a figurative meaning as well.
«Katalanisch» oder «Valencianisch»?: zum sprachlichen Sezessionismus im Land València
Authors: Radatz Hans-Ingo
Published: August 2023

In 1932, spelling rules for the native language of the Valencian Country were accepted in the Valencian city of Castelló. In fact, this decision meant the acceptance of the rules proposed by Pompeu Fabra for the Catalan language and consequently also the implicit acceptance of the essential identity of Valencian with Catalan. Despite this almost unanimous verdict of all the Valencian cultural forces, attempts at linguistic secessionism that seek to establish Valencian as a literary language independent of Catalan have continued to this day. With the recent electoral successes of a political party (Unió Valenciana) defending this secessionist position, the issue is once again very acute. Against this background, the article re-examines the main claims of secessionists in their academic and philological form, in order to determine the extent to which they can claim to be scientific. It is concluded that none of its central claims have been accepted by the rest of the international scientific community and that the so-called valencianophilia of secessionists often seems to be nothing more than an irrational and ill-concealed catalanophobia whose ultimate goal is la replacement of Catalan in the Valencian Country by Spanish.
Els poetes com a traductors: Kavafis en català, Kavafis en castellà
Authors: Nogueras Valdivieso Enrique J. , Sánchez Rodrigo Lourdes
Published: August 2023

This essay examines the translations made by poets of the poetry of the modern Greek writer Konstantinos Kavafis. The authors decide between technical and lyrical translations; Greek culture played a crucial role in the development of the latter. The differences between the two types of translation are methodological and aesthetic. The "poet-translator" always remains a poet and must therefore be careful not to change the original text too far. The most important Kavafis translations by the poets J. M. Álvarez (into Spanish) and Carles Riba (into Catalan) are compared; they are based on various criteria such as literalness or faithful reproduction.
Zum diachronen Wandel der phorischen Markierung beim katalanischen Relativum
Authors: Thielemann Werner
Published: August 2023

The grammatical area of ​​the relatives has a rather large variety of forms and possibilities of expression. Pronouns inherited from Latin can summarize the morphological and grammatical categories of the antecedent noun, they have the function of a resumptive. They allow the variation of the phoric configurations between the antecedent and the relative pronoun. However, in Catalan, there has been a remarkable change in the forms of expression from the 12th/13th centuries to the present day.

Historically, as can be seen in the comparison with Latin, there has been a permanent reduction and corruption of the phoric marks (j-marking) to the neutral marking of subject and direct complement in que. With this, the function of the resumptive is eliminated. Nowadays, the situation of Catalan is comparable to that of Spanish and Portuguese. What marks the Catalan changes in the area of ​​the relative, is the fact that the loss of the resumptive is accompanied by strategies of functional deviation that are highly interesting from the linguistic point of view.

As a typological consequence of the loss of the resumptive, today's Catalan prefers contact positions for the simple relatives. The uses in distance require the use of complex relatives: el qual, la qual, etc, which are considered heavy, inelegant and complicated.
Contribució dels media orals a la construcció d'un estàndard de masses plural: presència del dialecte nord-occidental en el llibre d'estil de les emissores radiofòniques de la CCRTV
Authors: Casals i Martorell Daniel

In the course of an analysis of the presence of elements of Northwestern Catalan in the style book of the Corporació Catalana de Ràdio i Televisió, it is found that these are primarily limited to phonetic peculiarities and largely neglect the morphosyntactic features. With the aim of supporting the media's preservation of Northwestern Catalan, it is suggested that the dialectal elements in the style books should be given greater consideration.
Quandoque bonus dormitat Corominas: Sobre arragua, laude, matar
Authors: Oroz Francisco J.
Published: August 2023

Caro Baroja suggested that Basque arragua ‘melting pot’ goes back etymologically to arrugia ‘gallery in a mine’, a word mentioned by Pliny. This totally aberrant etymology is mentioned by Coromines in both the DCELC and the DCECEH. For laude ‘burial stone’, he follows Covarrubias in accepting laudem ‘praise’, but the more plausible etymology is lapidem ‘stone’. However, when it comes to the etymology of matar ‘to kill’, Coromines rejects Covarrubias’ proposal mactare on behalf of implausible phonetic change; however, mactare was a very popular word, and, despite Coromines’ rejection, has to be considered as the best candidate for an etymology for matar.Keywords: Coromines / Joan, etymology, lexicography, Spanish language, Catalan language, Latin language, Basque language.
Vom Sprechen der Bilder: Variationen visueller Wahrnehmung bei Joan Brossa
Authors: Stahl Andrea
Published: August 2023

Summary: Approaching the works of Joan Brossa from an intermedial perspective, this essay seeks to examine his written experiments within the context of pictorial manifestations and thus intends to draw attention to his almost paradoxical engagement in the mediality of images. Starting out from his poesia visual i objecte, this essay wants to read individual examples as études of visual and written phenomena, as reflected compositions, which also find a paradigmatic expression in the theatre play Concert irregular per a pianista i cantatriu. These diverse border-crossings between image and text are not only relevant with regard to the aesthetics of image and language, but they also seem to question the very nature and character of such distinctions. In drawing attention to the revolving exchange of text and image, the works of Joan Brossa may be understood as an amusing divertimento, which starts again and again in order to reflect on the diversity of these borderzones.
