Authors: FATONI NUR ROCHMAN , SANTOSA RIYADI , . Prof. Djatmika
Published: April 2022

The spoken language phenomenon in social interaction, like in the sports discourse domain, is always exciting but rare to be discussed. This study focuses on the textual meaning of the supporting chants to support football players sung by supporters of the English Premier League (EPL), especially from the six biggest clubs (The Big Six). It is a qualitative descriptive study using content analysis. Within the Systemic Functional Linguistic approach, this study reveals textual meaning through the analysis of Theme and Rhyme consist of the Topical Theme; Unmarked Topical Theme, and Marked Topical Theme, Textual Theme, and Interpersonal Theme. The data are clauses taken from the football player supporting-chant lyrics from the supporters of the big six clubs. The analysis results are obtained through domain, taxonomy, componential and cultural themes analysis. Six chants are analyzed by textual meaning. Topical Theme analysis shows the development of a topic in the lyrics of supporting chants. Textual Theme indicates the connecting clause from the previous. Interpersonal Theme shows the interaction and transacting socially. These themes created a smooth information flow on the chant. Besides, it brought the meaning of these lyrics delivered well to the listener.
Decoding Social Standards for Children: A Case Study of Banjarese Songs
Authors: Krismanti Ninuk
Published: April 2022

This study is set to explain social standards decoded through traditional songs for Banjarese children. This study is carried out under a descriptive qualitative design. The data are taken from 36 songs sung for different purposes, from lullabies to traditional games companions. Observation and interviews are the techniques employed to collect the data. The observation and the interview are conducted in regions representing two distinguished dialects of the Banjar language: Banjar Hulu and Banjar Kuala. Cultural Linguistics is an approach for data analysis. The lyrics of investigated songs are registered into five categories reflecting different standards expected by Banjarese society for children. The results of the study show the desired and undesired social values believed by Banjarese society. These values are introduced to children, not through the media of preaching, but common practice of Banjarese families, singing.
Looking into the Language Status of Osing with Contrastive Analysis of the Basic Vocabulary of Osing and Malang Javanese
Authors: Nurhayani Ika , Hamamah Hamamah , Ningrum Dwi Ira , Delijar Ressi Maulidina
Published: April 2022

Osing is a language spoken by the majority of people in Banyuwangi, East Java. However, there is obscurity on its status whether it is considered as one of the Javanese dialects or as an independent language originated in Java. Some noted that the Osing is another version of Javanese, while the people living in the Banyuwangi Region regard the Osing as a distinct identity that differentiates it from the rest of the Javanese speaking regions in Central and East Java. Hence, this research aims to provide linguistic evidence on the lexical differences between the Osing and Malang Javanese. The research is significant because there is no previous research that provides linguistic evidence on the differences between the Osing and other Javanese dialects. Data of this study was obtained through eliciting the production of the basic vocabulary of the Osing and Malang Javanese speakers. The findings of the research provide evidence to the observation of previous linguists in that the Osing is not a linguistically separate language of Javanese.
Attitudinal Language of Flora and Fauna Discourse on an Indonesian Tourism Website: Appraisal in Ecolinguistics
Authors: Isti'anah Arina
Published: April 2022

This paper reports the appraisal analysis - particularly the attitudinal language - of Indonesian flora and fauna discourse on the official website of Indonesian tourism by examining 11 articles, accessed on www.Indonesia.travel. This paper qualitatively identifies the appraised features denoting Indonesian flora and fauna discourse and examined their appraising resources by applying Martin & White’s (2005) framework. Through the lens of interpersonal meaning, this paper criticizes how the website communicates through flora & fauna discourse in tourism to global readers. Findings reveal that affect, judgement, and appreciation function in several ways: introduce Indonesian endangered and endemic species, present the government’s seriousness to preserve the species, and promote the happiness and satisfaction tourists can feel when visiting the sites. From an ecolinguistics point of view, the website presents a beneficial discourse since it does not focus on feelings the tourists may have but the appreciation of the natural phenomena.
Phonological Process in Passive Verb Markers of Bahasa Bakumpai
Authors: Arief Yusuf Al
Published: April 2022

This research is about the phonological process which occurs in the forming of passive verbs in bahasa Bakumpai. The theory applied in this research is generative phonology. The object of this research is bahasa Bakumpai, one of the languages used by people in South and Central Borneo who live by Barito River. The research was conducted with descriptive qualitative method. The data collection was conducted by searching active and passive verbs in bahasa Bakumpai dictionary and verified by a native speaker. Result of the research shows that the prefix which becomes the passive marker is /i/ and when it is attached to stems begin with consonants, there are insertions of  consonants such as the [n], [m], [ng], and [ny] which are categorized as allophones since they occur in complementary distribution in the environments.

Positive semigroups in lattices and totally real number fields

Let L be a full-rank lattice in ℝ
d
and write L
+ for the semigroup of all vectors with nonnegative coordinates in L. We call a basis X for L positive if it is contained in L
+. There are infinitely many such bases, and each of them spans a conical semigroup S(X) consisting of all nonnegative integer linear combinations of the vectors of X. Such S(X) is a sub-semigroup of L
+, and we investigate the distribution of the gaps of S(X) in L
+, i.e. the points in L
+ ∖ S(X). We describe some basic properties and counting estimates for these gaps. Our main focus is on the restrictive successive minima of L
+ and of L
+ ∖ S(X), for which we produce bounds in the spirit of Minkowski’s successive minima theorem and its recent generalizations. We apply these results to obtain analogous bounds for the successive minima with respect to Weil heights of totally positive sub-semigroups of ideals in totally real number fields.

Published: April 2022

Bone marrow cell morphology has always been an important tool for the diagnosis of blood diseases. Still, it requires years of experience from a suitable person. Furthermore, the outcomes of their recognition are subjective and there is no objective quantitative standard. As a result, developing a deep learning automatic classification system for bone marrow cells is extremely important. However, typical classification machine learning systems only produce classification answers, and will not refuse to generate predictions when the prediction reliability is low. It will pose a big problem in some high-risk systems such as bone marrow cell recognition. This paper proposes a bone marrow cell classification method with rejected option (CMWRO) to classify 11 bone marrow cells. CMWRO is based on convolutional neural networks, ICP and SoftMax (CNN-ICP-SoftMax), containing a classifier with rejected option. When the rejected rate (RR) of tested samples is 0.3143, it can ensure that the precision, sensitivity, accuracy of the accepted samples reach 0.9921, 0.9917 and 0.9944 respectively. And the rejected samples will be handled by other ways, such as identified by doctors. Besides, the method has a good filtering effect on cell types that the classifier is not trained, such as abnormal cells and cells with less sample distribution. It can reach more than 82% in filtering efficiency. CMWRO improves the doctors’ trust in the results of accepted samples to a certain extent. They only need to carefully identify the samples that CMWRO refuses to recognize, and finally combines the two results. It can greatly improve the efficiency and accuracy of bone marrow cell recognition.

Published: April 2022

The heating performance of empty fruit bunch pellets (EFBPs) has been limited by its low energy density, high moisture, and ash content. Hence, microwave co-torrefaction (MCT) was performed with microwave heating unto waste oil mixed EFBP to produce high-energy biofuel. However, the non-homogeneous electromagnetic fields distribution in the microwave cavity results in an uneven heating behavior, producing the hot and cold spots. Hence, MCT coupled with helical lift was examined for its potential to improve heat distribution. The effect of temperature and types of waste oil on the proximate analysis and surface properties were studied. In comparison to the conventional torrefaction using a furnace (>30 min), MCT provided rapid heating (50–80°C·min−1) and a shorter process time (10 min). The use of helical lift with 2-dimensional movement – rotational (24 rpm·min−1) and vertical motion (5 cm·min−1) simultaneously, distributed microwave radiation uniformly for rapid heating. The proximate analysis demonstrated that the ash content was reduced from 8 to 3 wt%, and the highest fuel ratio of 2.0 was achieved. Additionally, the highly porous structure of EFBP biochar can act as an activated carbon precursor. MCT coupled with helical lift represents a promising approach to prevent hot spots during microwave heating.
The slenderness ratio effect on the response of closed-end pipe piles in liquefied and non-liquefied soil layers under coupled static-seismic loading

Published: April 2022

This study presents the findings of a 3D finite element modeling on the performance of a single pile under various slenderness ratios (25, 50, 75, 100). These percentages were assigned to cover the most commonly configuration used in such kind of piles. The effect of the soil condition (dry and saturated) on the pile response was also investigated. The pile was modeled as a linear elastic, the surrounded dry soil layers were simulated by adopting a modified Mohr-Coulomb model, and the saturated soil layers were simulated by the modified UBCSAND model. The soil-pile interaction was represented by interface elements with a reduction factor (R) of 0.6 in the loose sand layer and 0.7 in the dense sand layer. The study was compared with the findings of 1g shaking table tests which were performed with a slenderness ratio of 25. In the validation case, there was a clear correlation between the laboratory findings and the numerical analyses. It was observed that the failure mechanism is influenced by the soil condition and the slenderness ratio to some extent. Under the dry soil condition, no base pile deformation was observed; However, tip pile movement was observed under the saturated soil condition with pile slenderness ratios of 25 and 50. The findings of this study are also aimed to include an approximation of the long-term deformations at the ground surface which has experienced shaking.
Determining code parameters to achieve the maximum bandwidth efficiency in fiber-optic CDMA systems
Authors: Bogheiri Tahereh , Ghorban Sabbagh Abbasali
Published: April 2022

This paper first determines the generalized optical orthogonal code (GOOC) parameters to minimize the bit error probability in fiber-optic code division multiple access systems. The systems use on-off keying as the modulator and the optical AND logic gate as the receiver. In situations where the problem of finding the lowest bit error probability has more than one answer, we introduce and examine four approaches to choose the optimal answer. Finally, by employing a complete search of code parameters, we determine GOOC parameters (if there are any) to achieve the maximum bandwidth efficiency considering the design constraints, i.e., the number of network users and the maximum acceptable probability of error.

Published: April 2022

Objectives

Hypochondroplasia (HCH) is characterized by disproportionate short stature and regarded as a milder form of achondroplasia (ACH), which is another skeletal dysplasia, both caused by variants in fibroblast growth factor receptor 3 (FGFR3) gene. HCH diagnosis is based on the clinical features and skeletal survey findings. The most common FGFR3 variant in HCH affects the codon 540, leading to substitution of asparagine with lysine in about 70% of patients.

Case presentation

Herein, we described the clinical and radiographical manifestations of HCH in affected members of a Turkish family with very rare Asn540Thr (c.1619A>C) variant within hot spot of the gene for this condition.

Conclusions

This is a very rarely reported variant in the literature and this report is the first case with this variant in Turkish population. The report also presents the phenotypic variability within a family with the same variant, which is inherent to HCH.

Fenestrations in liver sinusoidal endothelial cells (LSEC) are transcellular nanopores of 50–350 nm diameter that facilitate bidirectional transport of solutes and macromolecules between the bloodstream and the parenchyma of the liver. Liver diseases, ageing, and various substances such as nicotine or ethanol can negatively influence LSECs fenestrations and lead to defenestration. Over the years, the diameter of fenestrations remained the main challenge for imaging of LSEC in vitro. Several microscopy, or rather nanoscopy, approaches have been used to quantify fenestrations in LSEC to assess the effect of drugs and, and toxins in different biological models. All techniques have their limitations, and measurements of the “true” size of fenestrations are hampered because of this. In this study, we approach the comparison of different types of microscopy in a correlative manner. We combine scanning electron microscopy (SEM) with optical nanoscopy methods such as structured illumination microscopy (SIM) or stimulated emission depletion (STED) microscopy. In addition, we combined atomic force microscopy (AFM) with SEM and STED, all to better understand the previously reported differences between the reports of fenestration dimensions. We conclude that sample dehydration alters fenestration diameters. Finally, we propose the combination of AFM with conventional microscopy that allows for easy super-resolution observation of the cell dynamics with additional chemical information that can be traced back for the whole experiment. Overall, by pairing the various types of imaging techniques that provide topological 2D/3D/label-free/chemical information we get a deeper insight into both limitations and strengths of each type microscopy when applied to fenestration analysis.
Optimizing Cr(VI) adsorption parameters on magnetite (Fe3O4) and manganese doped magnetite (MnxFe(3-x)O4) nanoparticles
Authors: Ouma Linda , Pholosi Agnes , Onani Martin
Published: April 2022

Magnetite as an adsorbent is efficient since iron oxides have high affinities for heavy metal pollutants and are environmentally friendly. Manganese oxides provide catalytic properties which are desirable during the remediation of multi valent pollutants. Magnetite (Fe3O4) and manganese doped magnetite (MnxFe(3-x)O4) nanoparticles were synthesized and characterized to determine the manganese doping effects on magnetite’s crystal and surface properties. Fe3O4 and MnxFe(3-x)O4 showed similarities in crystal morphology indicating that manganese doping did not alter the nature of Fe3O4 nanoparticles. Manganese doping improved magnetite’s thermal properties as well as its surface area providing improved adsorption characteristics. The as-synthesized particles were applied in the optimization of hexavalent chromium adsorption. Adsorption proceeded under similar conditions for both adsorbents indicating their structural similarities. Higher efficiencies were observed on the doped adsorbent due to increased surface area and the presence of additional functional groups. Solution pH significantly affected the adsorption process aiding in the reduction of Cr(VI) ions to the less toxic Cr(III) species. The adsorption distribution coefficient KD indicated that manganese doping significantly improved magnetite’s affinity for hexavalent chromium. Adsorption and reduction were determined to responsible for pollutant reduction in solution at optimal conditions of pH 2, 5 g/L and 100 mg/L for adsorbent mass and solution concentration.
Bounds for the spectral radius of nonnegative matrices and generalized Fibonacci matrices
Authors: Adam Maria , Aretaki Aikaterini
Published: April 2022

In this article, we determine upper and lower bounds for the spectral radius of nonnegative matrices. Introducing the notion of average 4-row sum of a nonnegative matrix, we extend various existing formulas for spectral radius bounds. We also refer to their equality cases if the matrix is irreducible, and we present numerical examples to make comparisons among them. Finally, we provide an application to special matrices such as the generalized Fibonacci matrices, which are widely used in applied mathematics and computer science problems.

This article provides an overview of methodological and technical issues that arise in the collection, indexing and use of spoken learner corpora, i. e. corpora containing spoken utterances of learners of a target language. After an introductory discussion of the most important special features of this type of corpus that distinguish it from written language learner corpora and spoken corpora with L1 speakers, we will go into more detail on questions of corpus design. The main part of the paper is then an overview of the methodological and technical procedures of the individual steps of collecting, indexing, providing and using spoken learner corpora. The main aim of this overview is to highlight practices that can be considered best practices according to the current state of research. Finally, we outline the challenges that still exist for this type of corpus.
Sprachliche Komplexität im Unterricht
Authors: Weiss Zarah , Lange-Schubert Kim , Geist Barbara , Meurers Detmar
Published: April 2022

We investigate the linguistic complexity of oral classroom interactions in late primary and early secondary school across German school types. The goal is to explore whether teachers and students align in terms of their use of the academic language register. We empirically base this investigation on transcriptions of teacher and student contributions during content matter lessons on the vaporisation and condensation of water. Across school types and grade levels, we compare the extent to which teachers offer language that is adaptively rich in linguistic constructs commonly associated with academic language, such as deagentivation, nominal style, and cohesive devices. Putting this in relation to the developing academic language competence of the students, we then compare the language offered by the teachers to the use of these academic language constructs in the students’ spoken language contributions. We discuss the methodological challenges arising from analyzing oral classroom interactions and from applying automatic linguistic complexity analyses to such data.

The current investigation applies the dual approach containing quantum chemical and molecular docking techniques to explore the potential of benzothiadiazole (BTz) and its derivatives as efficient electronic and bioactive materials. The charge transport, electronic and optical properties of BTz derivatives are explored by quantum chemical techniques. The density functional theory (DFT) and time dependent DFT (TD-DFT) at B3LYP/6-31G** level of theory utilized to optimize BTz and newly designed ligands at the ground and first excited states, respectively. The heteroatoms substitution effects on different properties of 4,7-bis(4-methylthiophene-2yl) benzo[c] [1,2,5]thiadiazole (BTz2T) as initial compound are studied at molecular level. Additionally, we also study the possible inhibition potential of COVID-19 from benzothiadiazole (BTz) containing derivatives by implementing the grid based molecular docking methods. All the newly designed ligands docked with the main protease (MPRO:PDB ID 6LU7) protein of COVID-19 through molecular docking methods. The studied compounds showed strong binding affinities with the binding site of MPRO ranging from −6.9 to −7.4 kcal/mol. Furthermore, the pharmacokinetic properties of the ligands are also studied. The analysis of these results indicates that the studied ligands might be promising drug candidates as well as suitable for photovoltaic applications.

J Strength Cond Res 36(6): 1749–1752, 2022—The purpose of this study was to explore the impact of coronavirus disease 2019 (COVID-19) restrictions on body composition, assessed by dual x-ray absorptiometry (DXA), between the 2020 postseason (pre–COVID-19 restrictions) and the 2021 postseason (post–COVID-19 restrictions) in collegiate football players (n = 50). In addition, a subset of athletes (n = 23) was used to explore body composition variables across 4 postseason time points. Body composition variables assessed were total and regional body fat percent, total mass, lean mass, fat mass, bone mineral content, bone mineral density, and visceral adipose tissue mass. Paired t-tests were used to determine differences between the 2020 postseason and the 2021 postseason in body composition variables. Analysis of variance with Tukey HSD post hoc tests assessed significant differences in total and regional body composition across 4 years while adjusting for multiple comparisons. There were no significant differences (p > 0.05) between postseason 2020 and postseason 2021 for all measures of body composition. In a subset of athletes, body composition was analyzed over a 4-year period of time. There were no significant differences between all 4 time points for all measures of body composition. In conclusion, body composition variables in this study's subjects were not affected because of coronavirus disease 2019 restrictions or over 4 years of their collegiate football career.
Local Path Planning Method for Unmanned Vehicle Based on Model Predictive Control in Hospital Environment
Authors: Ren Pingli
Published: April 2022

In order to address the obstacle avoidance problem of driverless vehicles in hospital environment, a local path planning method based on model predictive control is proposed. Firstly, the potential field model of driving environment factors including obstacles, environmental vehicles, roads, and target points is established by using artificial potential field theory. Then, based on model predictive control algorithm combined with driving environment potential field, trajectory planning and tracking are transformed into a unified constrained optimization problem. The objective function and constraint conditions of local path planning for unmanned vehicles are designed, and roll is introduced to the dynamic optimization mechanism. The simulation results show that the error between the path planning and the expected path is less than 0.1 m, the time consumption is at least 3.3 s, and it has strong robustness, which can effectively solve the obstacle avoidance problem of local path of unmanned vehicles.
Family Conflict Non-negotiation and HIV Disclosure Associated With ART Adherence in a Disadvantaged Population
Authors: Mitchell Mary M. , Tseng Tuo-Yen , Cruz-Oliver Dulce , Catanzarite Zachary , Hansen Eric , Knowlton Amy R.
Published: April 2022

Adherence to antiretroviral therapy (ART) is vital for reducing racial and gender disparities in morbidity and mortality among people living with HIV/AIDS (PLWH). Little research attention has been given to aspects of family functioning affecting ART adherence among PLWH vulnerable to disparities. Data were from n = 313 participants (93% African American) in the BEACON study, which recruited injection-drug-using PLWH on ART. Using factor analysis and longitudinal structural equation modeling, we found that current substance use and negative family conflict tactics (i.e., non-negotiation) predicted PLWH's lower probability of ART adherence at 12-month follow-up; and greater HIV disclosure to support network members predicted a higher probability of adherence. These findings suggest the importance of family and other support network members in this vulnerable population's ART adherence. Social network-focused interventions promoting prosocial response to conflict and negotiation skills are important for improving vulnerable PLWH's HIV outcomes and reducing health disparities.

Background: This study aimed to predict the pharmacokinetic and toxicological properties of lead flavonoids from the roots of T. egregia [praecansone A (1) and pongachalcone (2)], and to assess the gastroprotective effects and possible underlying mechanisms of the root extract in mice.

Methods: Quantitative and qualitative data for in silico absorption, distribution, metabolism, and excretion (ADME) analyses of the two flavonoids were acquired from the SwissADME database. Toxicity assessment was performed with the ProTox-II server. To evaluate the putative interactions of both flavonoids with opioid receptors and NO protein, we acquired structures of the targets (μ, κ, and δ-opioid receptors, and iNOS) in Homo sapiens from https://www.rcsb.org/. For docking studies, AutoDock 4.2 was used for ligand and target arrangement, and AutoDock Vina was used for calculations. For in vivo assays, mice were pretreated (per os) with T. egregia (2, 20, or 200 mg/kg). After 60 min, 99.9% ethanol (0.2 mL) was injected (per os). At 30 min after ethanol injection, the mice were euthanized, and the gastric damage, gastric levels of hemoglobin, glutathione content, and activity of superoxide dismutase and catalase were evaluated. To elucidate T. egregia mechanisms, we used misoprostol, a prostaglandin analog; indomethacin, an inhibitor of prostaglandin synthesis; L-arginine, an NO precursor; L-NAME, an antagonist of NO synthase; naloxone, an opioid antagonist; and morphine, an opioid agonist.

Results: In silico results showed that flavonoids (1) and (2) had favorable ADME properties and toxicity profiles, and exhibited satisfactory binding energies data (below −6.0 kcal/mol) when docked into their targets (μ, κ, and δ-opioid receptors, and iNOS). T. egregia decreased the ethanol-induced gastric damage and hemoglobin levels, and increased the glutathione content, and activity of superoxide dismutase and catalase. Naloxone and L-NAME, but not indomethacin, prevented T. egregia’s effects, thus suggesting that opioid receptors and NO are involved in T. egregia’s efficacy.

Conclusions: Flavonoids (1) and (2) exhibited favorable pharmacokinetic properties, showing high lethal dose, 50% (LD50; 3,800 and 2,500 mg/kg, respectively) values. Neither flavonoid was found to be hepatotoxic, carcinogenic, or cytotoxic to human cells. In vivo assays indicated that T. egregia ameliorated oxidative stress levels, and its mechanism is at least partially based on opioid receptors and NO. T. egregia may therefore be considered as a new gastroprotective strategy.
Stres i emocije u školi – percepcija zaposlenika i načini oporavka u funkciji psihološkog procvata
Authors: Cerinski Tomislav
Published: April 2022

Cilj istraživanja jest ispitati razlike u percepciji doživljenog stresa, načinima oporavka od stresa različitih grupa zaposlenika u školama, psihološkog procvata, zadovoljstva životom, pozitivnih i negativnih emocija s obzirom na vrstu zaposlenja i radni staž. Drugi cilj istraživanja hijerarhijskom je regresijskom analizom ispitati doprinos spola, radnoga staža, zadovoljstva životom, emocija, doživljenog stresa i načina oporavka od stresa objašnjenju psihološkog  procvata zaposlenika. Korištena je skala doživljenog stresa, skala zadovoljstva životom, PANAS skala, skala oporavka od doživljenog stresa i skala psihološkog procvata. Istraživanje je provedeno u petnaest osnovnih škola na ukupno 190 sudionika (166 žena i 24 muškarca). Među učiteljima i tehničkim osobljem razlike su utvrđene u psihološkom procvatu koji je viši kod učitelja, dok u razini zadovoljstva životom, pozitivnim i negativnom emocijama, doživljenom stresu i načinima oporavka od stresa razlike nisu utvrđene. Razlike s obzirom na radni staž u školi utvrđene su u psihološkom procvatu, zadovoljstvu životom i pozitivnim emocijama koji su viši kod ispitanika s manje radnoga staža u školi. Rezultati hijerarhijske regresijske analize ukazuju da se najveći dio psihološkog procvata učitelja može pojasniti pomoću zadovoljstva životom i pozitivnih emocija, dok se za tehničko osoblje pojašnjava pomoću zadovoljstva životom, doživljenog stresa, pozitivnih i negativnih emocija.
Perception of Distance Teaching as a Result of the COVID-19 Epidemic
Authors: Miletić Nikolina , Radoš Žaklina
Published: April 2022

With the onset of the so-called Covid 19 crisis in 2020, face-to-face teaching was temporarily replaced by distance learning in several European countries, including at Croatian schools of all skill levels. Because the crisis could not be foreseen and therefore sufficient preparations could not be made in time, not only did the teachers  unexpectedly switch to distance learning, but also the learners to home-based learning. This triggered several problems, among which the problem of work overload could be observed on all sides: be it on the part of teachers,learners or parents. This article examines the influence of distance learning and digital tools on students at the University of Zadar. In this research, it is assumed that the perception of distance learning and the associated use of digital media was assessed as quite negative due to the poor quality of distance learning. The reasons for the poor quality of distance learning are mainly due to the surprising change from face-to-face to distance learning and the associated inadequate preparation for distance learning, which caused general dissatisfaction at least in the first few weeks of distance learning. The results also point to systemic shortcomings in the quality and availability of information equipment and, in some cases, to the modest management of digital media by many teachers and students. However, distance learning offered an opportunity to reevaluate traditional face-to-face teaching and the role of teachers in society, as well as to illustrate the potentials and limitations of digital media.

Koprske besede v rokopisu Antea Gravisija iz leta 1881
Authors: Todorović Suzana , Lazarić Lorena
Published: April 2022

V prispevku se posvečamo izbranim izrazom (od A do D), ki jih je zapisal Koprčan Anteo Gravisi leta 1881. Narečni slovarček, ki ga sestavlja skupno 100 pojmov, je razdeljen na tri razdelke oz. stolpce – v prvem so zapisani izrazi, ki jih je ob koncu 19. stoletja uporabljal nižji sloj Koprčanov, sledijo besede, ki so jih uporabljali premožnejši meščani in intelektualci, v tretjem stolpcu pa avtor beleži knjižnoitalijanske ustreznice. Zanimalo nas je, katere od zapisanih besed so se ohranile v stoletju, ki je sledilo zapisu. Pri analizi smo se oprli na razpoložljivo narečjeslovno gradivo, zapisano v Kopru med letoma 1900 in 2020. Obravnavane izraze primerjamo z besedjem, ki ga poznajo istrskobeneško govoreči Istrani v sosednjih mestih Izola in Piran in jih povezujemoz njihovim zadnjim virom, opirajoč se na relevantno jezikoslovno literaturo.
Glagoli kretanja u nastavi ruskoga kao stranoga jezika
Authors: Ciumacenco Tereza Paulina , Modrić Hrabrov Žana
Published: April 2022

Rad je pisan kao smjernica nastavnicima ruskoga kao stranoga jezika koji poučavaju studente osnovnim glagolima kretanja, pod kojima podrazumijevamo glagole идти (‘ići’), ходить (‘ići’, ‘hodati’), ехать (‘ići’, ‘voziti se’) i ездить (‘ići’, ‘voziti se’). Daje se analiza triju udžbenika za početnike koji sadrže gramatički materijal, ilustracije, zadatke i tekstove koji pomažu usvajanju sadržaja, uz navođenje stručne terminologije na ruskome jeziku. Analizirali smo udžbenike Pojehali! 1 (Поехали! 1, 2009.), Žilibyli... 28 urokov russkogo jazyka dlja načinajuščih (Жили-были... 28 уроков русского языка для начинающих, 2016.) i Doroga v Rossiju 1 (Дорога в Россию 1, 2010.). U radu smo usredotočeni na studente kojima je hrvatski materinski jezik, stoga je ponuđen i prijevod glagola kretanja na hrvatski jezik. Ova tema može biti izuzetno zahtjevna za studente kojima ruski nije materinski jezik, s obzirom na to da u hrvatskome nema strogih pravila o upotrebi glagola kretanja – u hrvatskome možemoʻići automʼ i ʻputovati automʼ, dok se u ruskome može samo ʻputovati automʼ. U radu se daje i pregled dosadašnjih spoznaja i istraživanja dane tematike te se pojašnjava klasifikacija glagola kretanja i kronološki redoslijed uvođenja raznih skupina glagola kretanja u nastavu ruskoga kao stranoga jezika. Autorice predlažu višestruk pristup u obradi glagola kretanja, koristeći ne samo navedene udžbenike već i dodatne materijale te svoje primjere i ilustracije, kako bi olakšali studentima razumijevanje toga gradiva i njegovo usvajanje.

Síntesis y caracterización del complejo órgano-mineral (Metoprolol Succinato-Montmorillonita) para la liberación controlada del Metoprolol Succinato
Authors: Pérez Niño Laura Marcela , Candela Soto Angelica María , Camargo García Hernando Alberto
Published: April 2022

Debido a la necesidad actual de prolongar la acción de un fármaco y disminuir los efectos secundarios que se pueden generar en el paciente, se han desarrollado un gran número de investigaciones científicas que se centran en la implementación de sistemas que cubran las necesidades expuestas anteriormente, dando origen así a los sistemas de liberación controlada.

Este trabajo de investigación muestra la cinética de liberación del fármaco in vitro a partir de la síntesis del complejo Metoprolol Succinato (MPS)-montmorillonita (MMT) a pH 8. Laa presencia del fármaco en el espacio interlaminar del aluminosilicato se determinó mediante DRX de muestras policristalinas, y diferentes técnicas analíticas complementarias (Uv-Vis, FTIR y MEB), obteniendo como resultado que la introducción  del MPS en la montmorillonita se debió a las interacciones de enlaces de hidrógeno y ion-dipolo y además se logró un 60% de eficiencia de encapsulación.

Por último, para la cinetica de liberación del fármaco el modelo que se adaptó mejor a los datos obtenidos de la liberación en el fluido gástrico simulado (SGF) fue el modelo de Korsmeyer-Peppas y de primer orden para el fluido intestinal simulado (SIF).
Mode, the hub of multimodality: A case study of Oral-B® Toothpaste advertising
Authors: Dalamu Taofeek O.
Published: April 2022

This study investigates the nature of modal constructs in advertising commercial, operational in Oral-B® Toothpaste, to explain the mechanistic integration of modes, unified to generate holistic meaning. With the application of the mood system and kinesics concepts, the author is able to interpret the video for readers. Besides using statistical substances (tables and graphs) to explore the modes, one observes fragmentation of structures of some linguistic items such as The answer?, Easy, still fresh and strong. Repetition is a concern, where the communicator deploys the generic You, your teeth, and your mouth for a reason of emphasis. Communicative devices such as strong and healthy, and long lasting fresh breath (feeling) are details, exemplifying the Oral-B’s 2-IN-1 qualities. Gestural modes of smiling, observed in a repetitive speeches of Smile, Smile, Smile, and intimate and personal distances augment meanings as Social Actors 1 and 2 are indexical participants. Metaphorical professional actors and the dual 2-IN-1 features characterize the communication, projecting interchangeability. The advertisement is fascinating; yet, the metaphor of interchangeability could have been simplified for a purpose of sensitizing the illiterate.

Resumo Este artigo explora a pesquisa de um iñapakaita, benzedor, Afonso Fontes, homem baniwa do clã Hoohodene, por uma encantação xamânica para uma doença: a covid-19. Essa busca será compreendida como inventiva, nos termos da dialética wagneriana (2010), pois ocorre a partir de seus conhecimentos do cosmos, dos mundos mítico e atual, não humanos e humanos, indígenas e não indígenas. A análise das fórmulas verbais contidas na encantação de Afonso contra o coronavírus descreverá o seu caráter composicional, explicitando perspectivas a partir das quais são constituídas, bem como a agência xamânica atua na reordenação do cosmos. Por fim, realizam-se apontamentos de ordem especulativa, desde uma crítica xamânica, sobre o surgimento das doenças como conectadas a outros colapsos e associados ao modo de vida dos não indígenas no Antropoceno.

Performance of a vertical wind turbine with permanent magnet synchronous generator
Authors: Roga Sukanta , Kisku Vivek , Datta Subir
Published: April 2022

The performance of a wind energy conversion system based on a vertical axis wind turbine and a permanent magnet synchronous generator was evaluated in a computational study. A power point tracking approach was used to determine the maximum output power from the system. The technique used in the study utilised the voltage and current from the generator as inputs to generate a reference voltage, which was then compared with the direct current output voltage obtained at the load resistor. A proportional integral controller was used to tune the error between the reference and output voltage. The generated output was then compared with a pulse generator before being fed to the insulated-gate bipolar transistor switch as a pulse width modulation signal. In the software, a system model was designed, and its simulation analysis was done. The input parameters for the wind turbines, generator and boost converters were selected to achieve optimal output in terms of voltage, current, power, rotor speed, power coefficient, electromagnetic torque and mechanical torque. The computational results of the simulated wind energy conversion system were gathered and its performance examined.
Centrifuge modelling of wave-induced seabed response in clay
Authors: Wu Leiye , Kong Deqiong , Zhu Bin , Chen Renpeng , Chen Yunmin
Published: April 2022

This paper describes a programme of centrifuge tests investigating the behaviour of clayey seabed under wave loading using an in-flight wave loading system. Three model seabeds of kaolin clay capturing typical unconsolidated, normally consolidated and overconsolidated soil responses were considered, with each seabed experiencing several episodes of wave loading and resting. Data acquisition measures included pore pressure transducers, accelerometer, bender elements and T-bar penetrometers. The depth-wise distribution of excess pore pressure, soil strength and modulus, as well as the motion of the liquefied layer of the seabed, was monitored throughout to enable a thorough investigation into the liquefaction and reconsolidation features of the soil. For the unconsolidated and normally consolidated soils, remarkable development of residual pore pressure was observed, and there was evidence that the strength/modulus recovery cannot be achieved by the surficial soil within a prototype time of 15 days. Within a certain depth below this surficial layer, there was a drastic increase in undrained strength, and this phenomenon was carefully examined by a modified moving-boundary model. For the overconsolidated soil, the build-up of residual pore pressure was rather limited, but discernible amplification of oscillatory pore pressure amplitude was observed. Implications for practice in offshore engineering are discussed based on the experimental findings.
