Corrosion Fatigue of Standard Duplex Stainless Steel X2CrNiMoN22-5-3 under Rotation Bending Load in Northern German Basin Environment
Authors: Wolf Marcus , Pfennig Anja
Published: September 2023

Standard duplex stainless steel X2CrNiMoN22-5-3 is resistant to both, corrosion and mechanical stress, but corrosion fatigue (CF) lowers the lifetime expectancy in a geothermal environment such as the Northern German Basin. Laboratory experiments used the in-situ electrolyte at 369 K in a specifically designed corrosion chamber applying rotation bending cyclic load to failure. CF behaviour was compared to pure push-pull load. Corrosion kinetics are independent of the load applied. Failure is initiated by pits resulting in mechanical degradation. Increased thickness of the passivating layer surrounding pits enhances degradation or delamination. Also, sharp notches located along the pit edge increase notch effects and stress concentration consequently leading to fast crack propagation and early failure.

Published: September 2023

This work aims at comparing the mechanical properties of Rice-Husk-Ash-Cement (RHA) concrete produced from magnetized water and normal water. Cement was replaced with 25% RHA being the optimum value from previous research. Water was magnetized by a magnetic device fabricated by the research team and level of magnetization was determined using magnetic field sensor application. The chemical composition of RHA shows that it contained 89.42% of oxides to be used as a pozzolan. Magnetization reduced total dissolved solid, total soluble solid, chloride content and surface tension while pH increased. The workability of magnetized and normal water concrete samples was determined. It was magnetized water concrete samples that gave higher workability than normal water concrete. Compressive, Flexural and Split tensile strengths of magnetized and normal water concrete were determined at 7, 14, 28 and 56 days of curing by immersion in portable water. Magnetization shown higher influence on early strengths of concrete. Compressive, Flexural and Split tensile strengths of concrete improved between 13.25%-18.63%, 14.83%-18.02% and 9.80%-31.63%, respectively when magnetized water was introduced during concrete production. STATA package was used to analysis the data. The descriptive statistics show that mean, standard deviation error and standard deviation for concrete produced with magnetized water were all higher than that of concrete produced with normal water for all properties tested. However, inferential statistics show that there is no significant difference in the mean compressive, flexural and tensile strengths of concrete produced with magnetized water and normal water since P-value obtained was higher than the error margin of 0.05(P>0.05) for all the tested properties of concrete.

Published: September 2023

The use of aluminum alloys in the manufacture of hydropneumatic systems components is very known. However, the knowledge of their behavior under cavitational demands, determinated of flow of the working liquid, is limited. For this reason, in recent years, the older research, carried out on this type of material and on some of its alloys, regarding the resistance to cavity erosion, has been resumed, especially since the mechanical properties and reduced mass are an advantage for the parts that work in this conditions (ship propellers, pumps and bodies of hydraulic devices, etc.). Therefore, the results of this paper are in step with the new researches, highlighting the behavior and resistance to the erosion produced by vibrating cavitation on the aluminum alloy 6082 subjected to the thermal aging treatment at 140 °C, with a holding time of 12 hours. The performance evaluation is based on the characteristic curves of the cavity, the specific parameters and the macro and microstructural investigations. The comparison with the delivered state shows a double increase in resistance from the cavitational erosion created by the shock waves and microjets.

The good mechanical properties of aluminum alloy 2017 A have determined its use in a wide range of applications in which cavitational solocitations occur, such as hydraulic actuation installations, heat engine blocks, boat propellers and sloops, pumps in the cooling system of thermal engines, wings and ogives of airplanes. Currently, research is focused on the development of procedures for improving the resistance to cavitational erosion of these materials. This paper presents the results of the research on the cavitation erosion behavior of the material subjected to thermal aging treatment at different temperatures of 140 °C and 180 °C respectively and a constant holding time of 12 hours. The research was carried out according to the ASTM G32-2016 norms, on a vibrating device with piezoceramic crystals from the Cavitation Laboratory of the Polytechnic University of Timisoara. The research results, based on characteristic curves, mechanical properties, micro and macro structural images, showed that the sample kept for 12 h at a temperature of 180 °C is weaker than the control sample, during the sample time kept for 12 h at a temperature of 140 °C, has a small increase, even if, compared to the control sample (without heat treatment), the hardness is lower.

Impact of Green Supply Chain Management Practices on Triple Bottom Line Performance and Moderating Effect of Institutional Pressure
Authors: Gunasekara K. R. H. L.
Published: September 2023

Parallel to the rapid population growth, manufacturing as one of the supply chain practices should be increased to fulfilling their requirements. Due to the advancement of industry and technology, the needs of human beings are constantly changing and the process of supplying goods and services becomes more complex. Reasoning competition and profit maximization, the manufacturing sector creates severe environmental problems and social problems as well. Under this scenario, conducting research has begun on how manufacturing should take place while conserving the environment. Accordingly, previous literature confirms that green supply chain management is the appropriate solution for overcoming environmental issues.Although several research studies have been conducted to examine this relationship, moderating effects of various pressures on this relationship have not been investigated within the Sri Lankan context. Therefore, this research aims to identify the impact of green supply chain management practices on firms’ triple-bottom-line performance and also examine the moderating effects of regulatory pressure on this relationship. A hundred large-scale manufacturing companies were selected as the sample through the purposive sampling method. Moreover, a questionnaire survey was employed for the data collection, and data was analyzed through confirmatory factor analysis using PLS-SEM software. Findings indicate that significant positive relationship between green supply chain management practices and triple bottom line performance i.e., environmental, economic, and social. Moreover, findings accentuate that regulation pressure moderates the relationship of green supply chain management practices only with environmental and social performances. This explored knowledge will encourage practitioners to implement green practices within their supply chains and it enables the country to achieve sustainable goals.

Authors: Opatha H. H. D. N. P.
Published: September 2023

One of the most useful models of personality is the Big Five Dimensions of Personality (BFDP). Regarding the BFDP, a gap exists in the empirical knowledge of the BFDP among senior bank managers in Sri Lanka. Five conceptual research questions were formulated, and they were answered through desk research. Furthermore, two empirical research questions were formulated and answered through a structured survey among 129 senior managers working in one of the largest and most successful commercial banks in Sri Lanka. The instrument used to measure the phenomenon of the BFDP was based on an operational definition, i.e., the summated rating received on a 20-item, 5-point Likert scale, and its content validity, construct validity, and internal reliability were ensured. The empirical findings revealed that, on average, senior bank managers in Sri Lanka have a BFDP to a high extent, and the degree of the BFDP of senior managers in the selected bank is higher than that of senior managers in general.
Perception of Entrepreneurial Ecosystem Factors: Comparison among Students and Entrepreneurs
Authors: Prajapati Bikram
Published: September 2023

The entrepreneurial ecosystem refers to the dynamic interplay of socioeconomic factors that enable entrepreneurs to establish and expand their businesses. The degree of entrepreneurial activity is heavily influenced by how entrepreneurs perceive this ecosystem. This research examines the perceptions of such ecosystems in Nepal. Specifically, the study investigates the differences in understanding entrepreneurial ecosystem factors between students and entrepreneurs. To accomplish this, a survey consisting of a set of questions was administered to 343 students and 158 entrepreneurs. It was observed that, compared to students, entrepreneurs rated significantly lower in all the ecosystem factors except for entrepreneurial capabilities. An independent samples t-test result showed a significant difference in the perception of the entrepreneurship ecosystem factors among students and entrepreneurs, except for social-cultural support. The study suggested that a high level of entrepreneurial ecosystem development is not required to influence entrepreneurial activity; improvement in some factors, such as family and social support, skill-building education, and training, might increase entrepreneurial intentions.
Francisella tularensis: a zoonotic pathogen among wild rodents and arthropods - a possible threat in future
Authors: Priyantha M. A. R.
Published: September 2023

Francisella tularensis is a Gram-negative coccobacillus and an aerobic bacterium. It causes a zoonotic disease called tularemia in humans. Four subspecies have been found in F. tularensis as F. tularensis subsp. Tularensis (Type A strains), F. tularensis subsp. Holarctica (Type B strains), F. tularensis subsp. mediasiatica, and F. tularensis subsp. Novicida. Rearing rabbits and different kinds of rodents as pets are becoming popular in Sri Lanka, veterinarians need to be knowledgeable on emerging pathogens such as F. tularensis, to diagnose the disease within a short time. Therefore, the objective of this paper is to update veterinarians on possible emerging infections to improve the health of pets and to minimize possible zoonotic infections. The clinical outcome caused by Francisella is a debilitating febrile disease in humans. Francisella has been isolated from hundreds of animal species in the world. Being a diverse host range, associated ecological factors relating transmission of Francisella in the environment is largely unknown. F. tularensis type A was reported to be common in North America while occasionally found in Europe. Type B was found commonly in the Northern hemisphere and in Australia. Tularemia is a sporadic disease, and a small infectious dose is required for an infection in humans. The clinical signs and symptoms of tularaemia depend on the route of infection. Six types of clinical forms were identified as ulceroglandular, glandular, oropharyngeal, oculoglandular, pneumonic and typhoidal in humans. Diagnosis of tularemia in humans is based on epidemiology, clinical findings and laboratory confirmation. Microagglutination test, indirect immunofluorescence assay (IFA) and Enzymelinked immunosorbent assay ELISA are widely used as diagnostic tests. Several conventional and qPCR have been optimized to detect the organism in clinical samples. Antimicrobials such as aminoglycosides, tetracycline, quinolones, and chloramphenicol were used to minimize clinical complications. Utilization of treated water, usage of gloves on handling wild rabbits and rodents, thorough cooking of bush meat, usage of insect repellents, protection of stored food from rodents, wearing masks, ticks-free clothes, keeping away from weeds, cleaning pets from external parasites have been identified as the main preventive strategies against tularaemia in human. No commercial vaccine is found in the market yet against F. tularensis. This can be an emerging and threatening disease in the future with ongoing changes in arthropod parasites in the ecosystem followed by climatic changes in the world.
Mechanism of TLR4-Mediated Anti-Inflammatory Response Induced by Exopolysaccharide from the Probiotic Bacillus subtilis
Authors: Zamora-Pineda Jesus , Kalinina Olga , Sperling Anne I , Knight Katherine L
Published: September 2023

Intestinal inflammatory diseases affect millions of people worldwide, and one class of drugs showing promise toward treatment of several inflammatory diseases is probiotics. Numerous studies have been performed using probiotics to prevent and treat intestinal inflammatory diseases. Most of these studies used intact bacteria, and neither the active molecule nor the molecular mechanisms by which they affect immune responses are known. We have shown that the probiotic Bacillus subtilis is anti-inflammatory and can protect mice from acute colitis induced by the enteric pathogen Citrobacter rodentium. We identified and purified the active molecule, exopolysaccharide (EPS), and showed that it protects mice from C. rodentium–induced colitis by inducing anti-inflammatory M2 macrophages or inhibitory dendritic cells (DCs), both of which inhibit excessive T cell responses. We showed previously that EPS affects macrophages and DCs in a TLR4-dependent manner, and in the current study we asked how EPS induces these anti-inflammatory cells and how they function to inhibit T cells. By investigating the signaling downstream of TLR4 that leads to acquisition of inhibitory properties of macrophages and DCs, we found that EPS induces expression of the inhibitory molecule IDO in bone marrow–derived DCs, and that inhibition of T cell proliferation by IDO-expressing bone marrow–derived DCs utilizes the kynurenine/aryl hydrocarbon receptor circuit. Furthermore, unlike LPS, EPS does not induce inflammatory cytokines upon injection in vivo, directly demonstrating different outcomes induced by two different TLR4 agonists.

OBJECTIVE:

This study aims to identify the motivations behind orthodontic re-treatment in Saudi Arabia.

MATERIALS AND METHODS:

This is a cross-sectional study performed through a patient questionnaire. The questionnaire elicited data on the respondents' socio-demographic data, type of previous orthodontic treatment, retention, satisfaction level, and reasons for undergoing orthodontic re-treatment.

RESULTS:

Four hundred and nineteen responses were received during the study period from June to July 2022. The result showed a pre-dominant female predilection (83, 29%), with the majority belonging to the 21–25 age group (47.26%). Most participants had had one previous orthodontic treatment (77%), with an active treatment time of approximately 1–3 years (55.85%). There was no significant difference between the satisfaction of outcomes after the initial treatment and at the time of the survey. Most participants received retention appliances (69.45%) and were informed about the importance of appliances. The type of retention was mainly removable retainers (47.5%). Around one-third of the sample (31.98%) were interested in seeking orthodontic re-treatment, with self-motivation as the primary drive and improving the smile as the predominant reason.

CONCLUSION:

The study's findings show that a large portion of the population is seeking orthodontic re-treatment, which must be considered. Self-motivation was a driving force rather than external motivation. The most common reason for seeking orthodontic re-treatment was to improve their smile and the increased esthetic demand.
Quantitative assessment of root resorption in TAD-aided anchorage with and without RAP: A CBCT study on en masse retraction cases
Authors: Jose Amala Rita , Shetty Nillan K. , Shalu Sneha , Prasad K Amritha , Susan Thankam C. , Shetty Suhani Sudhakar
Published: September 2023

INTRODUCTION:

The purpose of this study was to evaluate the amount of root resorption with mini implant-aided anchorage, with and without inducing the regional acceleratory phenomenon (RAP) in en masse retraction cases using cone-beam computed tomography (CBCT).

METHODS:

Thirty patients requiring therapeutic extraction of all first premolars were included in the study and randomly divided into two groups of fifteen patients each (groups I and II). Patients of both groups underwent retraction using mini implants. In patients of group II, the RAP was initiated before starting retraction. For each patient, CBCT of the maxillary and mandibular anterior region was taken before treatment and after retraction to evaluate root length changes.

RESULTS:

The amount of root resorption post-retraction was lesser in group II as compared to group I for the maxillary canine, mandibular canines, and mandibular lateral incisors. When the amount of root resorption was scored according to the Malmgren index, a greater percentage of teeth in group I (17.8%) showed root resorption of score of 3 as compared to group II (6.1%).

CONCLUSION:

The results of the study show that the RAP caused reduced root resorption, but its effect was localized to the area where it was induced. When mini implants are used for absolute anchorage during en masse retraction, the RAP can be induced to reduce the root resorption that results from increased treatment time associated with implant-aided retraction.
Influence of maxillary first molar rotation on the severity of dental class II malocclusion: A cross-sectional study
Authors: Alexander Lidhiya , A Shanaj Doulath , Arun V
Published: September 2023

AIM:

The aim of the study was to evaluate and assess the influence of maxillary molar rotation on severity of dental class II malocclusion.

MATERIALS AND METHODS:

The study comprised of 4 different groups namely, 1/4th class II malocclusion, 2/4th class II malocclusion, 3/4th class II malocclusion and full class II malocclusion involving sample size of 20,15,16 and 12. The samples were subjected to digital evaluation of maxillary 1st permanent molar rotation using 4 parameters namely angle of Friel, Ricketts E-Line, angle of Henry and Premolar angle.

RESULTS:

The results were subjected to statistical analysis using one way ANOVA wherein group IV (Full class II malocclusion) exhibited a greater rotational value. On evaluation, angle of Friel exhibited a mean of 59.6±1.61 degrees, Ricketts E-Line was found to be 12.3±1.77mm while angle of Henry showed a mean of 19±3.19 degrees and premolar angle was 12.5±5.83 degrees.

CONCLUSION:

On evaluating molar rotation using angle of Friel, Ricketts E-Line, angle of Henry and premolar angle, full cusp class II malocclusion presented higher degree of mesiopalatal rotation maxillary molar rotation. With increasing mesiopalatal rotation, the severity of molar relation also increased from 1/4th to full class II. Hence the maxillary molar spatial position along the long axis majorly influences the molar relation wherein a full cusp class II molar relation exhibits higher degree of molar rotation.

Authors: Abutayyem Huda , Alam Mohammad Khursheed , Kanwal Bushra , Alswairki Haytham Jamil , Alogaibi Yahya Abdullah
Published: September 2023

A variety of metals and alloys are employed in the field of orthodontics, primary of which happen to be the construction of wires. Through this systematic review, we aimed to assess the various metallurgical characteristics of the said metals and alloys. Four hundred and eighty-two documents in total were found after a thorough search of the online journals, and 169 of the papers were initially chosen. Ultimately, 16 documents were selected that satisfied the necessary inclusion and exclusion criteria, primarily in vitro studies, literature reviews, and comparative analyses. NiTi alloy was found to be the most commonly used alloy in construction of orthodontic wires across all the studies that we had selected for our review. It also had better performance and consistency in terms of its usage as depicted by the meta-analysis performed, with stainless steel wires being a close second primarily due to its lesser cost compared to the former. Metallurgy and orthodontics are inextricably linked with one another. The various components of orthodontics such as wires, pliers, and other instruments utilize the metallurgical characteristics of metals and alloys that are specially prepared for the challenges of this field.

AIM:

To translate the orthodontic experience questionnaire into Malayalam, an Indian language, and assess its validity and reliability in the Kerala population.

MATERIALS AND METHODS:

The original questionnaire, which was developed in English, was translated into Malayalam. Face validity was assessed, and minor changes were made, followed by a content validity assessment by an expert panel. The final version was given to 324 patients who marked their responses on a Likert scale. Internal consistency reliability was tested using Cronbach's alpha, and test-retest reliability was tested using the intraclass correlation coefficient. Principal component factor analysis was performed to regroup the valid items.

RESULTS:

The principal component factor analysis revealed three domains. Reliability assessed by Cronbach's alpha of the whole questionnaire was 0.799, and that of the three domains was 0.73, 0.71, and 0.71, respectively. The test-retest reliability was found to be good (0.798).

CONCLUSION:

The Malayalam version of the orthodontic experience questionnaire was found to be content valid with good reliability. To obtain a successful treatment result, an orthodontist must be aware of these and this questionnaire, with adequate validity and reliability, has been designed to achieve this in the Malayalam-speaking population.
The effect of ceramic surface conditioning on bond strength of metallic brackets: An in vitro study
Authors: Ferreira Rita , Pereira Pedro Mariano , Pitschieller Ricardo , Proença Luis , Bugaighis Iman
Published: September 2023

OBJECTIVE:

To compare the shear bond strength (SBS) of brackets bonded to three different types of ceramic surfaces (feldspathic ceramic, lithium disilicate ceramic, and zirconia), conditioned with either hydrofluoric acid or sandblasting, using Assure® Plus All bonding agent.

MATERIALS AND METHODS:

A total of 72 monolithic CAD/CAM ceramic specimens were divided into six groups of 12 samples. Three groups (G1: feldspathic ceramic, G3: lithium disilicate ceramic, G5: zirconia surfaces) were conditioned with 9.6% hydrofluoric acid, while the remaining three (G2, G4, G6; with ceramic type in the same order as the previous three groups) were prepared with 50 μm aluminum oxide sandblasting. Premolar brackets were bonded using light-cured Assure® Plus All. The SBS and adhesive remnant index (ARI) were recorded and submitted to inferential analysis using one-way analysis of variance and Kruskal–Wallis tests, respectively. The significance level was set at 5% (P ≤ 0.05).

RESULTS:

The mean SBS values for the three different ceramic groups conditioned with hydrofluoric acid (G1: 7.2 ± 1.5 MPa, G3: 9.3 ± 2.3 MPa, G5: 8.5 ± 2.0 MPa) were significantly higher than those obtained for the groups prepared by sandblasting before bonding (G2: 7.5 ± 1.8 MPa, G4: 4.4 ± 2.0 MPa, G6: 4.3 ± 2.8 MPa).

CONCLUSIONS:

The hydrofluoric acid treatment produced a favorable SBS for all three examined ceramic types before bracket bonding with Assure® Plus All. In comparison, sandblasting yielded a satisfactory SBS only with feldspathic surfaces. Furthermore, the ARI indicated a higher frequency of mixed-adhesive failures except for lithium disilicate conditioned with sandblasting. Therefore, using hydrofluoric acid is likely to be especially recommended when the clinician is not aware of the brand of ceramic restorative material.
Nickel and copper ion release, deflection and the surface roughness of copper-nickel-titanium orthodontic archwire in sodium fluoride solution
Authors: Sufarnap Erliera , Harahap Kholidina Imanda , Cynthiana Sally , Reza Muhammad
Published: September 2023

OBJECTIVE:

Sodium fluoride (NaF) is commonly used in oral hygiene products, leading to corrosion and reduced archwire properties. In addition, ion release can cause allergies and become toxic to the oral environment. This research aimed to observe the Nickel (Ni) and Copper (Cu) ions released that affected initial corrosion as deflection and surface roughness changed in the Copper-Nickel-Titanium (CuNiTi) archwire.

MATERIAL AND METHODS:

The total samples were 54 copper-nickel-titanium (CuNiTi-Tanzo, American orthodontic®) archwires immersed in three solutions. Artificial saliva was used in the control group NaF 0.05%, and a NaF 0.15% solution was used in the intervention groups (n = 6). The groups were divided into three observation times (two, four, and six weeks). Cu and Ni ions released, deflection, the surface roughness of the archwires, and solution acidities were recorded and analyzed.

RESULTS:

Ni and Cu ion release and surface roughness of the CuNiTi archwires significantly increased as the NaF concentration increased. The Ni ion release improved along the immersion period; the opposite was true for the Cu ion release. The solutions became more alkaline after the CuNiTi archwires were immersed. The pH and the archwires' deflections of the three solutions did not show significant differences.

CONCLUSION:

The NaF increased Cu-Ni ion release and surface roughness but not the deflection force of the CuNiTi. The increase was affected by the concentration and duration of immersion.
A fast image inpainting algorithm based on an adaptive scanning strategy
Authors: Guo H. R. , Wang W. H.
Published: September 2023

OBJECTIVES: In exemplar-based image inpainting algorithms, there are often issues with the calculation of patch similarity for matching, suboptimal strategies for selecting matching patches, and low inpainting speed.METHODS: This paper first uses the variable scale cross-scan block line progressive scan to solve the problem of slow scanning speed and invalid priority formula. Then, an improved weight similarity formula is used for searching to solve the problem of poor computing strategy for similar matching patches. The search range of matching patches gradually increases from small to large until globally searching for similar matching patches to improve the efficiency of inpainting. To further improve the correctness of matching patch selection, this paper uses six levels of priority matching criteria for screening.RESULTS: The experimental results show that the inpainting effect of the proposed method is significantly improved in subjective vision, and the structural similarity (SSIM), peak signal-to-noise ratio (PSNR), and inpainting speed of the inpainting results are all improved.CONCLUSION: For different types of images, the proposed method has a better inpainting effect and higher inpainting speed than the other three advanced methods.
Attention ConvMixer Model and Application for Fish Species Classification

Published: September 2023

Exploring the ocean has always been one of the foremost challenges for humankind, and fish classification is one of the crucial tasks in this endeavor. Manual fish classification methods, although accurate, consume significant time, money, and effort, while computer-based methods such as image processing and traditional machine learning often fall short of achieving high accuracy. Recently, deep convolutional neural networks have demonstrated their capability to ensure both time efficiency and accuracy in this task. However, deep convolutional networks typically have a large number of parameters, requiring substantial training time, and the convolutional operations lack attentional mechanisms. Therefore, in this paper, we propose the AttentionConvMixer neural network with Priority Channel Attention (PCA) and Priority Spatial Attention (PSA). The proposed approach exhibits good performance across all three fish classification datasets without introducing any additional parameters, thus demonstrating the effectiveness of our proposed method.

Published: September 2023

The reliable operation of power systems on the lunar surface is crucial for critical research activities and supporting life. These systems are standalone or interconnected grids that integrate intermittent power sources and distributed energy storage. Lunar microgrids must be highly reliable, reconfigurable, and efficient. To meet these requirements, we propose the flexible DC energy router (FeDER), a modular and scalable power management unit for interconnected lunar DC microgrids. The FeDER integrates local energy storage and addresses various microgrid power management needs such as fault management, stability enhancement, power flow regulation, and power quality improvement. The lunar DC microgrids' design, protection, and control are achieved using a three-layered approach: (1) graph theory, (2) energy management system, and (3) smart resistor control. The lunar power grid architecture is introduced and the FeDER stability enhancement is implemented in the OPAL-RT platform. The effectiveness of the FeDER in dc grids is demonstrated with a load power step test case.

Poučevanje maternega in tujega jezika prihodnjih prevajalcev (in tolmačev) bi moralo biti zato prilagojeno njihovim specializiranim potrebam, s čimer se v številnih pogledih uvršča v okvir jezikov stroke (Cerezo Herrero 2018, Koletnik 2019).
Na Oddelku za prevodoslovje Univerze v Mariboru zato že od leta 2012 ob začetku študija preverjamo jezikovno zmožnost študentov angleškega programa, od leta 2013 pa tudi obseg besedišča, in rezultate upoštevamo pri načrtovanju jezikovnega pouka. Medtem ko so bile v preteklosti že objavljene delne analize uspešnosti tako prilagojenega poučevanja (prim. Koletnik 2020 v povezavi z razvijanjem prevajalske zmožnosti, Koletnik in Tement 2020 za razvijanje besedišča), celostna analiza doslej še ni bila izvedena. Prav tako je deziderat primerjava oziroma korelacija izhodiščne zmožnosti s splošnim uspehom študentov pri jezikovnih predmetih na prevajalskem študiju, ki jo prinaša pričujoči članek. Dosedanje analize so sicer pokazale, da se za dodiplomski prevajalski študij angleškega jezika na Univerzi v Mariboru odločajo študenti z visoko razvito jezikovno zmožnostjo, kar predstavlja dodaten izziv pri snovanju učnih aktivnosti in materialov, obenem pa je dobra popotnica za magistrski študij prevajanja in tolmačenja.
Prevodi in njihov doprinos k oblikovanju evropske kulturne dediščine
Authors: Chevrel Yves , Golja Petruša

Možnosti, za katere se je odločila šesterica del, objavljenih med leti 2004 in 2019, nas spodbujajo k izoblikovanju zgodovine, ki bo prikazala doprinos prevodov k evropski kulturni dediščini. Ti predstavljajo vlogo kulturnih transferjev na področjih religije in filozofije, zgodovinopisja, prava in znanosti. Zgodovina prevodov, ki neprekinjeno krožijo po Evropi, je tako še posebej ustrezno orodje za razumevanje oblikovanja »evropske civilizacije«.
Ali sploh še potrebujemo prevajalce?
Authors: Mezeg Adriana
Published: September 2023

Zaradi izboljšanja strojnih prevajalnikov v zadnjih letih se pogosto sprašujemo, ali bi ta orodja nekoč lahko nadomestila človeškega prevajalca. V članku predstavimo rezultate ankete o uporabi strojnih prevajalnikov med študenti francoščine ljubljanskega Oddelka za prevajalstvo, nato pa se posvetimo analizi napak v prevodih štirih besedil iz francoščine v slovenščino, ki smo jih pridobili z Google Prevajalnikom in DeepLom. Analiza je pokazala, da je DeepL nekoliko boljši od Google Prevajalnika, ki se je z leti sicer izboljšal, vendar kakovost strojnega prevoda iz francoščine v slovenščino še vedno ni na ravni človeškega, pri čemer izstopajo leksikalne napake pred slovničnimi in slogovnimi napakami. Večina študentov si pri prevajanju iz francoščine v slovenščino pomaga s prevajalniki in meni, da so zaradi tega njihovi prevodi boljši, obenem pa ne vedo, ali imajo dovolj znanja za njihovo popravljanje. Zato ni dovolj, da študente naučimo zgolj to, da bodo sami znali odlično prevajati, temveč se moramo pri njihovem izobraževanju osredotočiti tudi na razvoj kompetenc za popravljanje strojnih prevodov, saj obstaja velika verjetnost, da bodo prevajalci v prihodnosti večinoma postali popravljalci strojnih prevodov.
Feministisches Handeln in der literarischen Übersetzung sexueller Gewalt
Authors: Montes Antonia
Published: September 2023

In diesem Artikel soll das feministische Übersetzen als Translationskonzeption dargestellt werden, deren Ziel es ist, im Translationsprozess durch bestimmte feministische Übersetzungsverfahren offen Widerstand gegen patriarchialische Strukturen zu leisten sowie gegen Geschlechter-Asymmetrien vorzugehen. Die Thematik der sexuellen Gewalt an Frauen ist ein Thema, das auch in der deutschen Literatur aufgegriffen wird. Am Beispiel der Kurzgeschichte Volksfest von Ferdinand von Schirach (2010) und deren Übersetzung ins Spanische soll gezeigt werden, wie feministisches Übersetzen sogenannte ‘neutrale und objektive’ Übersetzungsverfahren in Frage stellt, bei denen am Ausgangstext nur die linguistisch obligatorischen Veränderungen vorgenommen wurden. Dieser Artikel geht auch auf die literarische Translator:innenausbildung ein, denn Studierende sollten dafür sensibilisiert werden, dass gerade feministische Themen wie sexuelle Gewalt eine besondere translatorische Annäherung bedürfen, wobei der Ansatz des feministischen Übersetzens die ideale Grundlage dafür bildet.
Es wird dafür plädiert, dass gerade bei literarischen Texten, die als Thema sexuelle/sexualisierte Gewalt an Frauen haben, das feministische Übersetzungsverfahren als Translationskonzeption angewendet werden sollte. Deswegen sollten literarische Texte mit dieser Thematik, die bereits übersetzt sind, einer Neuübersetzung mit feministischen Übersetzungskriterien unterzogen werden.
Gerade auch im Hinblck auf die literarische Übersetzerausbildung sollten die Studierenden dafür sensibilisiert werden, dass gerade Themen wie sexuelle/sexualisierte Gewalt eine besondere translatorische Annäherung bedürfen, wobei der Ansatz des feministischen Übersetzens die ideale Grundlage für eine tolertante,  frauensensible und -gerechte literarische Zieltextproduktion darstellt.
La « Décabase »
Authors: Coste Bénédicte
Published: September 2023

Ma post-doctorante, Caroline Crépiat, et moi-même avons développé une base de données réunissant les traductions des textes anglais décadents parues dans 10 périodiques français entre 1885 et 1914 (decabase.u-bourgogne.fr). Cette base de données montre la présence importante de la poésie et de la prose traduites, tant en tant que telles que dans les critiques de livres, en tant que traductions fragmentaires. Ces traductions – et les commentaires qu’elles suscitent au sein des périodiques qui les publient ou dans d’autres revues – constituent la première importation de textes en langue étrangère dans les lettres françaises. L’intérêt qu’elles ont suscité a souvent conduit à entreprendre des traductions d’ouvrages plus complets et de recueils.
Cet article présente la « Décabase », montre l’importance de la traduction dans le corpus de périodiques sélectionnés et trace des pistes de recherche dans un domaine qui commence à susciter l’intérêt des chercheurs en traduction et en études consacrées aux périodiques. Ce dernier nécessite l’adoption d’une approche interdisciplinaire à l’intersection des études consacrées aux périodiques, des études de réception et de traduction littéraire ainsi que de l’histoire de la traduction.
Med prevajanjem in prevodi
Authors: Inkret Andreja
Published: September 2023

Prispevek obravnava prevajanje v kontekstu poučevanja tujih jezikov, pri čemer se v prvi vrsti osredotoča na didaktiko pouka klasičnih jezikov. Pouk stare grščine in latinščine ima za osrednji cilj bralno razumevanje izvirnih besedil in zato dolgo tradicijo ukvarjanja z vprašanjem prevajanja v didaktične namene. To se zdi zanimivo predvsem spričo sodobnih teoretičnih smernic, ki prevajanju – potem ko je po zatonu slovnično-prevajalske metode v veliki meri izgubilo veljavo – ponovno odmerjajo pomembnejše mesto v okviru pouka modernih tujih jezikov. Prispevek tako opozarja na možno vlogo, ki jo ima prevajanje lahko predvsem pri delu z zahtevnejšo tujejezično književnostjo in razvijanju kompetence bralnega razumevanja. Obenem poudarja, da je prevajanje lahko dobrodošlo orodje tudi pri razvijanju kompetenc, ki so vezane na literarnost obravnavanih besedil. To se zdi še posebej pomenljivo v obdobju, v katerem lahko zasledimo močne tendence po vračanju literarnih besedil v učilnice modernih tujih jezikov.

Local breeds are key components of livestock farming systems. They are part of livestock biodiversity and this diversity has been threatened since the second half of the 20th century by their replacement with animals from specialized breeds. The multiple benefits of farming systems using local breeds – provision of goods, landscape and environmental management, and uses related to cultural and heritage dimensions – have long been recognized and used to argue for their conservation. However, the notion of ecosystem services is rarely used to analyze those benefits. This article presents a qualitative approach to the provision of ecosystem services by farming systems that use livestock biodiversity. Based on diverse case studies of breeds from several species, we propose an analytical framework that accounts for how a service is qualified, who is concerned by the services identified, the role of the breed in the process of service provision, and interactions between services. Finally, the framework considers the links between the provision of services and the management of the breeds. We discuss to what extent the notion of ecosystem services is useful in dealing with the multiple benefits from farming systems using local breeds.
Maker-Breaker domination game on trees when Staller wins
Authors: Bujtás Csilla , Dokyeesun Pakanun , Klavžar Sandi
Published: September 2023

In the Maker-Breaker domination game played on a graph $G$, Dominator's goal
is to select a dominating set and Staller's goal is to claim a closed
neighborhood of some vertex. We study the cases when Staller can win the game.
If Dominator (resp., Staller) starts the game, then $\gamma_{\rm SMB}(G)$
(resp., $\gamma_{\rm SMB}'(G)$) denotes the minimum number of moves Staller
needs to win. For every positive integer $k$, trees $T$ with $\gamma_{\rm
SMB}'(T)=k$ are characterized and a general upper bound on $\gamma_{\rm SMB}'$
is proved. Let $S = S(n_1,\dots, n_\ell)$ be the subdivided star obtained from
the star with $\ell$ edges by subdividing its edges $n_1-1, \ldots, n_\ell-1$
times, respectively. Then $\gamma_{\rm SMB}'(S)$ is determined in all the cases
except when $\ell\ge 4$ and each $n_i$ is even. The simplest formula is
obtained when there are at least two odd $n_i$s. If $n_1$ and $n_2$ are the two
smallest such numbers, then $\gamma_{\rm SMB}'(S(n_1,\dots, n_\ell))=\lceil
\log_2(n_1+n_2+1)\rceil$. For caterpillars, exact formulas for $\gamma_{\rm
SMB}$ and for $\gamma_{\rm SMB}'$ are established.
Resynchronized Uniformization and Definability Problems for Rational Relations
Authors: Löding Christof , Winter Sarah
Published: September 2023

Regular synchronization languages can be used to define rational relations of
finite words, and to characterize subclasses of rational relations, like
automatic or recognizable relations. We provide a systematic study of the
decidability of uniformization and definability problems for subclasses of
rational relations defined in terms of such synchronization languages. We
rephrase known results in this setting and complete the picture by adding
several new decidability and undecidability results.
