Authors: Velmurugan Natarajan , Sathishkumar Yesupatham , Sonowal Shashanka , Pang Ka-Lai , Lee Yang Soo 
Published: November 2021

Abstract
Long-chain saturated and polyunsaturated fatty acids of two new thraustochytrid isolates cultured from Taiwan mangroves, Aurantiochytrium sp. IMB169 and Aurantiochytrium sp. IMB171, were characterized through their cell growth and development in relation to their intracellular lipid accumulation using transmission electron microscopy. Flow cytometry in combination with the lipophilic fluorescent dye BODIPY 505/515 was used to stain and characterize intracellular lipid bodies in the two isolates. The transmission electron microscopy and flow cytometry analyses revealed a progressive accumulation of lipid products in IMB169 and IMB171. Further, selective BODIPY stained cells were successfully separated and enriched using flow cytometry at single cell level. Among the two isolates, IMB169 was found to produce a high level of docosahexaenoic acid. The qualitative and analytical results obtained using electron microscopy and flow cytometry studies were validated by gas chromatography (GC). In addition, a quantitative baseline was established using cell growth, flow cytometry and GC analyses for developing an efficient bioprocessing methodology to selectively enrich thraustochytrids phenotypes with desirable characteristics.
Googleology for second language learning
Authors: Giampieri Patrizia 
Published: November 2021

Abstract
The World Wide Web has often been considered too vast to be consulted for linguistic purposes or for language learning. This paper will explore whether second language learners can be taught how to navigate the web (i.e., how to perform Google linguistic research, or “Googleology”), in order to improve their language skills. To this aim, a 2 h trial lesson was organized. The trial lesson was delivered to 78 apprentices, divided into groups of 10–15, over a period of six months. During the lesson, the participants were taught how to work with Google Advanced Search syntax. At the end of the lesson, they applied the newly-acquired skills by completing a few tasks concerning term and/or collocational search. The paper findings will highlight that, despite initial hesitation or inaccuracies in completing the exercises, the tasks were performed well. The participants considered the lesson interesting, useful and enjoyable. They felt engaged irrespective of the level of their second language (L2) knowledge, and were more confident in approaching Google Search for linguistic purposes.
Fostering autonomy in learners with special needs: a specialized e-learning course
Authors: Tóthová Lenka , Sedláčková Jitka 
Published: November 2021

Abstract
International engagement has become a priority and is regarded as a means to improve the quality of students’ education and their future social and professional success. It may, however, pose a major challenge for some higher education students. One of the vulnerable groups is that of learners with special needs, and particularly Deaf, deaf and hard of hearing students. These learners are limited in their chances to interact in spoken/written foreign languages and in the learning opportunities they can join. This, by extension, has an unfavourable impact on their possibilities of engaging in study abroad. Based on the experience with a newly launched e-learning course “Online English for International Mobilities”, the present paper discusses the need for building effective FL learning strategies in Deaf, deaf and hard of hearing students in connection with the process of academic internationalisation. The main argument is for the need to foster students’ ability to self-regulate, reduce their teacher dependency and reliance on directed learning, and to encourage them to take responsibility for their own learning. Secondly, the paper provides a comparison of two pilot runs of the course from the perspective of (online) classroom dynamics and cooperation. While the course is built to be as autonomous as possible and benefits from the advantages of the e-learning format, great importance is given to group dynamics and cooperation via discussion forums and online chats. It also takes advantage of the considerable benefits of individualized, personalized feedback being provided by teachers on selected assignments.
Translingual transcultural competence: student agency, teacher guidance, and program support
Authors: Kunschak Claudia 
Published: November 2021

Abstract
An increasingly interconnected world requires people to become versatile communicators in a variety of different settings. Language centers have a critical role to play in this process by offering language and culture training in multiple languages to students, professionals and the wider community alike. They may do so from the perspective of developing plurilingual pluricultural competence, translingual transcultural competence or intercultural communicative competence and intercultural citizenship. This paper takes as its framework translingual transcultural competence, which not only reflects the current trend of transnationalism and diasporic communities, but also emphasizes the need to be critically aware, culturally reflective and socially sensitive. In order to better understand affordances and challenges in developing this competence, or set of competences, the author surveyed and interviewed students and teachers at one university-affiliated language center offering 30 languages besides German as the main language of study. Students at all proficiency levels as well as native and non-native teachers of the language taught were included in the study. Whereas the student survey investigated awareness and attitude, identity and community as well as the autonomy and agency of students in the program, teacher interviews provided insights into program parameters, classroom pedagogy and out-of-class projects. Findings from the study indicate a strong foundation in multicompetence thinking with some challenges in developing the transcultural component.
Shifting towards the action-oriented approach in Higher Education: language learners’ perceptions
Authors: Jaleniauskiene Evelina 
Published: November 2021

Abstract
In the updated version of the Common European Framework of Reference for Languages: Learning, Teaching, Assessment – Companion Volume (Council of Europe 2020), the Action-Oriented Approach is highlighted as the most viable approach for learning languages. The present study explored students’ reflections on the collaborative project based on this approach. The project was offered to the learners at a tertiary level during a course of English (C1 level). Analysis of the data revealed that the project appeared to be useful for the development of both general and communicative language competences. Although collaboration was indicated among the most satisfactory aspects, the learners also experienced the most difficulties with it. Despite the finding that most students considered such a project to be of acceptable difficulty, their level of satisfaction differed significantly. The results point to some potential challenges while shifting to the Action-Oriented Approach as a more active language learning approach. Not all students may be ready for the new type of language learning which requires higher levels of cognitive effort and more collaboration in comparison to traditional language classes. As this approach marks a significant turn in language education, it is anticipated that both the detailed presentation of the project and students’ reflections on it will help to increase the awareness of other language educators seeking to design quality action-based projects.
An initial assessment of the academic and professional profile of modern foreign languages’ teachers in UK higher education
Authors: Coderch Marion 
Published: November 2021

Abstract
The aim of this activity report is to provide an initial appraisal of the current makeup of the professional group of modern foreign language teachers in UK Higher Education. The report is in two parts: a literature review that identifies the main defining qualities of modern foreign languages teachers, and an evaluation of the professional and academic profiles of language teachers in UK higher education, as displayed in the institutional websites of the universities where they work. The analysis of the data collected corroborates the characteristics identified in the literature: the low status of teaching staff, the often unconventional entry paths into the profession, the prevalence of the “native speaker” construct as a desirable feature in candidates who aspire to teach the language, the disparity in qualifications of language teachers, and their low engagement in research activities. Future prospects involve the verification (or amendment, where necessary) of the data collected with accounts from individuals who work as language teachers.
Speedometer reliability in regard to road traffic sustainability
Authors: Ondruš Ján , Gogola Marián , Čulík Kristián , Kampf Rudolf , Bartuška Ladislav 
Published: November 2021

AbstractThe speedometer with radar head is a device displaying the instantaneous speed of vehicles in both the directions of the traffic lane. Interactive with the video, it collects and effectively interprets particular statistic data, such as the number of passed vehicles, classification of vehicles, exceeded speed, drivers´ behavior – speed change right before the measuring device, etc. The video is synchronized with the radar. In the areas where speedometer is installed, it is predicted that about 30% of the drivers slow down in front of the measuring device and about 60–90% of vehicles slow down after passing the device. The speedometer also serves as a light decelerator with respect to safe and sustainable traffic. The aim of the research was to carry out and subsequently to evaluate the three profile reviews executed on the selected road section under specific light and traffic conditions. After that, the evaluated data was compared with the real data gained by the respective reviews. The result of such comparison showed the measure of reliability and accuracy of the speedometer.
New migrants, new challenges? – Activating multilingual resources for understanding mathematics: institutional and interactional factors
Authors: Krause Arne , Wagner Jonas , Redder Angelika , Prediger Susanne 
Published: November 2021

Abstract
New adolescent migrants from Arabic-speaking countries face complex challenges when participating in regular mathematics classes in Germany: They have been educated in their family language(s) and are obliged to adapt to a new (second or target) language and to different styles of teaching. In contrast, 3rd generation multilingual students, who usually are schooled in German only, have rarely ever used their family languages in mathematics. This poses different challenges for the introduction of multilingual teaching and learning. By comparing German-Turkish 3rd generation students and adolescent refugees from Arabic speaking countries, both in 7th grade, this paper argues for the epistemic importance of considering “multilingual profiles” (i. e. including individual languages and history of migration) for linguistic analyses as well as for didactical designs of learning opportunities. For this purpose, a functional pragmatic discourse analysis of transcribed video-data from bilingual mathematics sessions with up to four multilingual students was conducted. This allows to characterize discursive multilingual profiles and to distinguish different perspectives on and verbalizations of mathematical concepts (in this case: fractions) in classroom discourse. Furthermore, language-specific interfaces of mental and linguistic processes are unfolded which enable new insights into conceptual understanding. The analysis focusses on the languages German, Turkish and Arabic and on 7th grade mathematics classes. The paper shows that the activation of multilingual resources in mathematics classrooms sets a promising approach for a sustainable integration of migrants, since they are enabled to use their subject-related knowledge which, in the long run, holds the potential support for the acquisition of the target language on a pre-academic level.

Quantum chemical studies on structural, spectroscopic, nonlinear optical, and thermodynamic properties of the 1,2,4-triazole compound
Authors: Medetalibeyoğlu Hilal , Yüksek Haydar 
Published: November 2021

AbstractIn this study, the structure of 4-[4-(diethylamino)-benzylideneamino]-5-benzyl-2H-1,2,4-triazol-3(4H)-one (DBT) was examined through spectroscopic and theoretical analyses. In this respect, the geometrical, vibrational frequency,1H and13C-nuclear magnetic resonance (NMR) chemical shifts, thermodynamic, hyperpolarizability, and electronic properties including the highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO–LUMO) energies of DBT as a potential non-linear optical (NLO) material were investigated using density functional theory at the B3LYP level with the 6-311G basis set.1H and13C-NMR chemical shifts of DBT with the gauge-invariant atomic orbital and continuous set of gauge transformation methods (in the solvents) were estimated, and the computed chemical shift values displayed excellent alignment with observed ones. Time-dependent density-functional theory (TD-DFT) calculations with the integral equation formalism polarizable continuum model within various solvents and gas phases in the ground state were used to evaluate UV-vis absorption and fluorescence emission wavelengths. Thermodynamic parameters including enthalpy, heat capacity, and entropy for DBT were also calculated at various temperatures. Moreover, calculations of the NLO were carried out to obtain the title compound’s electric dipole moment and polarizability properties. To illustrate the effect of the theoretical method on the spectroscopic and structural properties of DBT, experimental data of structural and spectroscopic parameters were used. The correlational analysis results were observed to indicate a strong relationship between the experimental and theoretical results.

Abstract

Pinus sylvestris L., Pinus sibirica Du Tour, Picea obovata Ledeb., and Larix sibirica Ledeb. are important forest tree species in Mongolia. The radial variations of wood anatomical characteristics, physical and mechanical properties were evaluated by linear or nonlinear mixed-effects models for effective wood utilization of those of conifers. Many of these wood properties either increased or decreased from the pith to the bark and then became nearly constant based on the selected models. The properties of mature wood were estimated by nonlinear mixed-effects models, suggesting that P. sylvestris and L. sibirica are suitable as structural lumber, P. sibirica can be used for furniture and other interior products, and P. obovata is suitable for structural lumber as well as for furniture or interior products.
„Ein Unbekanntes ist nur der Geschmack“. Zu Levin Ludwig Schückings literatursoziologischem Ansatz
Authors: Schell Sandra , Venzl Tilman 
Published: November 2021

Abstract
The article reconstructs Levin Ludwig Schücking’s History of Taste as a method of writing literary history. Moreover, it lays out, for the first time, the cultural and literary-political dimensions of his approach by considering the context of the history of literary studies comprehensively. The article demonstrates how Schücking refers to sociology in a twofold manner: as a way of scholarly thinking that is related to certain methodological techniques, and as a way to overcome the “crisis of modernity” manifested in the rift between authors and readers in literary life.

Abstract
The article examines the admission of ‘sociology of literature’ in the standard literary reference works of the Weimar Republic. In addition to handbooks, these include above all the Reallexikon der deutschen Literaturgeschichte and the Sachwörterbuch für Deutschkunde. The study examines how the method is understood, whom it is associated with, what examples are given, and what significance it had in the methodological discourse at the time.
Controllable oxidation of cyclohexanone to produce sodium adipate in an electrochemical reactor with a Pt NPs/Ti membrane electrode
Authors: Cui Zhaowei , Wang Hong , Chen Zishang , Zhang Yujun , Tian Hao , Yin Zhen , Li Jianxin 
Published: November 2021

Abstract
An electrocatalytic membrane reactor (ECMR) with an anode consisting of Pt nanoparticles (NPs) loaded on a Ti membrane electrode (Pt NPs/Ti) was designed to oxidize cyclohexanone (K) to produce sodium adipate (SA) under mild conditions. The effects of residence time, reaction temperature, current density and initial K concentration on K conversion were investigated. Optimization experiments were conducted to determine the effects of and interactions between different operating parameters on K conversion using a central composite design within the response surface methodology. A 88.3% conversion of K and 99% selectivity to SA were obtained by the ECMR under the optimum conditions of reaction temperature = 30.8 °C, K concentration = 22.54 mmol L−1, residence time = 25 min and current density = 2.07 mA cm−2. The high performance of the ECMR is attributed to electrocatalytic oxidation (at the Pt NPs/Ti electrode), convection-enhanced mass transfer, and the timely removal of the desired products.

Authors: Valsakumar Abitone , Dinesh Sujatha , Prasad Ganesh , Shetty Prashanth 
Published: November 2021

Abstract

Objectives
Mud pack or compress is an easily accessible, cost-effective, efficient treatment modality used in naturopathy to manage and prevent various chronic illnesses. This study sought to elucidate the effectiveness of cold spinal mud packs on improving neuro-cardiac parameters among hypertensive individuals.

Methods
A total of 100 hypertensive subjects aged 30–50 years were randomly allocated into two groups: Cold spinal mud pack (CSMP) and prone rest. Blood Pressure (BP) and Heart Rate Variability (HRV) were assessed at three-time points: Baseline, After 20 min (T1), After 60 min (T2). This single-blinded randomized controlled trial was registered in the Clinical Trials Registry-India (CTRI/2019/12/022492).

Results
After 20 min of CSMP showed a statistically significant reduction (p<0.01) in mean values of Systolic BP, Diastolic BP, and in HRV attained statistically significant change (p<0.01) in mean score in the frequency domain except for Very low-frequency power (VLF) and a significant difference found in the mean score of time-domain values (p<0.01) when compared to control group and 95% confidence interval (CI) will be provided for each effect.

Conclusions
CSMP reduces the sympathetic tone and shifts the sympathovagal balance in favor of parasympathetic dominance, contributing to a decrease in BP and effective changes in components of HRV.

Published: November 2021

Abstract

Objectives
To assess the incidence of testicular adrenal rest tumors (TARTs) among male children with congenital adrenal hyperplasia (CAH) in tertiary care centers.

Methods
All male children aged 1–14 years diagnosed with CAH due to 21-hydroxylase deficiency (21 HOD), 11β-hydroxylase deficiency, and 3β-hydroxysteroid dehydrogenase deficiency, confirmed by biochemical and/or genetic testing, underwent scrotal ultrasound examination to identify TARTs. After receiving the diagnosed patients’ data, patients’ electronic medical records were accessed to collect demographic data and scrotal ultrasound results, along with growth parameters and specific biochemical test results within 2 months of the ultrasound.

Results
TARTs were observed in 5 (10.9%) of 46 male children with CAH. Four patients with positive findings had 21 HOD classical CAH with salt loss and one had 21 HOD simple virilizing classical CAH. All patients had poor compliance and stage 2 bilateral TARTs. Three TART-positive patients (60.0%) had high ACTH levels, 5 patients (100%) had elevated 17-OHP levels, and 5 patients (100%) had advanced bone age. The youngest patient with positive findings was 4 years old.

Conclusions
The prevalence of TARTs increases with age and can be present in young males with classical CAH with 21 HOD. It is associated with elevated 17-hydroxyprogesterone (17-OHP) and advanced bone age SDS. TARTs are less likely to be associated with nonclassical CAH with 21 HOD or other less common CAHs due to 11β-hydroxylase deficiencies and 3β-hydroxysteroid dehydrogenase deficiencies in children. Our study recommends early and routine screening of TARTs in children with CAH.
