Published: April 2021

Abstract
Eight new localities of the rare, strictly protected macrophyte Vallisneria spiralis have been recorded during a comprehensive survey of water bodies in Croatia. One record is located in the Mediterranean Region, in Butoniga Reservoir, while the remaining records are from the Continental Region, the majority of them situated along the Kupa River. Vallisneria spiralis occurred in slightly basic and alkaline environments and in a wide range of nutrient availability. In Continental localities, the species was present within Myriophyllo-Nupharetum luteae of the alliance Nymphaeion-albae, while in Butoniga, it occurred within the vegetation of the alliance Potamogetonion. Prior to our research, the species was recorded in Croatia only twice, with the older record dating back to the 19th century and the second from recent years, but neither one was confirmed in later surveys. The low number of records of V. spiralis, in spite of a wide-ranging search through hundreds of localities, confirmed the rare status of this species, although the reasons for such limited distribution remain unclear, especially bearing in mind that suitable aquatic habitats are quite widespread in the country.

Abstract
We studied the site ecology of Salvia brachyodon (Lamiaceae), a narrow endemic of the eastern Adriatic, which is now restricted to only three sites, using the sigmatistic method and numerical analyses. Four floristically and ecologically well-defined groups of stands, representing different syntaxa, were identified, corresponding to the sampling sites. The majority of stands represent dry eastern (sub)Mediterranean rocky grasslands at different successional stages towards (sub)Mediterranean forest vegetation. Compared to the evolutionary and ecologically closely related and sympatric S. officinalis, the morphologically easily distinguishable S. brachyodon differs in its flowering phenology and prefers relatively cooler, wetter, deeper and nutrient richer soils, which are developed on dolomite or dolomitic limestone at higher elevated sites. Despite its ability to cope with interspecific competition by means of clonal reproduction better than its congener, the populations are severely threatened by abandonment of traditional land use and by fires, making the species endangered (EN) according to IUCN criteria.

Published: April 2021

Abstract
This study aimed to perform motor action and biomechanical analysis of techniques in female judo athletes separated by weight categories of 638 female bouts (103 extra lightweight <48 kg, 140 half lightweight 48>52 kg, 65 lightweight 52>57 kg, 73 half middleweight 57>63 kg, 77 middleweight 63>70 kg, 80 half heavyweight 70>78 kg and 60 heavyweight >78 kg). All bouts were analyzed following the phases of approach, gripping, defensive action, attack, also biomechanical analysis of techniques and groundwork was performed (p ≤ .05). Results indicated that lightweight athletes presented lower attempts to grip, right collar grip and left collar grip frequencies than other categories. Extra lightweight judokas presented lower right back grip and left back and sleeve grip frequencies as well as lower occurrence of techniques with arm and leg lever scored than half lightweight athletes, while half lightweight athletes demonstrated higher frequency of techniques with waist lever variable scored than lightweight ones. These findings should be considered for training prescription.
What is a real measure of corporate liquidity
Authors: Ertugrul Melik , Coskun Ali 
Published: April 2021

Abstract
The financial health hypothesis argues that the valuation multiple of book value of equity (earnings) increases (decreases) as financial health decreases. By considering the liquidity dimension of financial health, we analyze an accrual-based liquidity ratio (current ratio) and a cash-based liquidity ratio (OCF ratio) from the perspective of this hypothesis. Using the median values of these ratios, we divide the sample consisting of listed firms on Borsa Istanbul during 2009–2018 into two and document the ensuing outcomes. Valuation multiples of book value of equity and earnings are reported as being statistically indifferent between low-liquid and high-liquid subgroups obtained for the median current ratio. However, the valuation multiple of book value of equity (earnings) significantly increases (decreases) for the low-liquid subgroup below the median OCF ratio. As the latter is consistent with the financial health hypothesis, this study reveals that the OCF ratio is a more convenient and reliable measure of liquidity than the current ratio.
Hungarian dialects in Slovakia. Present and future
Authors: Sándorová Anna , Vančo Ildikó 
Published: April 2021

Abstract
The present situation of Hungarian dialects in Slovakia is similar in many respects to that of the dialects of other Hungarian regions (including dialects in Hungary and the cross-border dialects as well), but it also differs from them in other respects. It is well known that there are more differences between Slovakia Hungarian dialects and dialects in Hungary and fewer differences between the former and other minority Hungarian dialects. Intense change in the dialects and the spread of the standard at the expense of the dialects are all-Hungarian phenomena, but the extent of these varies greatly between the situation in Hungary and that of the minorities. The language use of the Hungarian minorities is more dialectal and the spread of the standard is slower among them in Hungary, but their common feature is that changes usually approach the standard. In our study, we discuss the present situation of Hungarian dialects in Slovakia, and attitudinal studies on Slovakia Hungarian dialects and the effect of attitudes on the use of dialectal elements in everyday language use.
The application of functional cognitive linguistic pedagogy under the conditions of linguistic minorities
Authors: Nagy Gábor Tolcsvai 
Published: April 2021

Abstract
The paper gives an overview of the general and special factors of L2 learning of Hungarian minorities across the borders of Hungary, that is, in Slovakia. Indigenous minorities like Hungarians in Slovakia are strongly interested in fluent state language knowledge. Still, the state school system failed to work out and implement a suitable language pedagogy for linguistic minorities, since the state curriculum comprised only one type of Slovak lessons, the one for pupils speaking Slovak as their mother tongue. This curriculum does not consider the special needs for bilingual pupils (on different levels of bilingualism) and those growing up in pure minority environment. The paper introduces functional cognitive linguistics as a usage-based theory and descriptive activity that gives new methods for L2 learning and teaching, building on the vernacular linguistic and conceptual knowledge of the pupils, focusing on the meaning – form pairs of linguistic expressions both in the vernacular and the second (state) language. In the second part, certain grammatical units are discussed as the topic of functional language pedagogy: lexical units and their grammatical adjustment to the syntactic and semantic structure of the sentence, or metaphor in use. In the third part, the topics of the previous section are treated in a comparative Hungarian – Slovak style, as examples of L2 teaching methodology.
The paradigm of Hungarian -ik verbs and their current position in the verb system and the language use
Authors: Kozmács István 
Published: April 2021

Abstract
The article deals with the typology of the paradigms of Hungarian verb and describes the phenomenon of the originally medial-reflexive -ik verbs of Hungarian. The article presents the problems caused by the use of the paradigm revived by the Hungarian language renewal in the 19th century and compares the use of the -ik verbs by bilingual Hungarian students in Slovakia with their contemporaries in Hungary. The result of the study shows that Hungarian high school students in Slovakia are more likely to search for standard variants compared to their Hungarian peers if they feel that using a non-standard solution could lead to a negative value judgment.
Applying Automatic Mapping Processing By GMT to Bathymetric and Geophysical Data: Cascadia Subduction Zone, Pacific Ocean
Authors: Lemenkova Polina 
Published: April 2021

AbstractThe Cascadia Trench is stretching along the convergent plate boundaries of Pacific Plate, North America Plate and Juan De Fuca Plate. It is an important geomorphological structural feature in the north-east Pacific Ocean. The aim of the paper is to analyse the geomorphology of the Cascadia Trench west of Vancouver Island (Canada and USA) using the GMT cartographic scripting toolset. The unique geomorphological feature of the Cascadia Trench is that the thick sediment layer completely obscures the subduction zone and abyssal hills. This results in the asymmetric profile in the cross-section of the trench. Bathymetric data were extracted from the GEBCO 2019 dataset (15 arc-second grid), sediment thickness by the GlobSed dataset. Due to the dominance of high sedimentary rate and complexity of the tectonic processes and geologic settings, Cascadia Trench develops very specific asymmetric geomorphic shape comparing to the typical V-form. The results of the geomorphic modelling show that eastern side of the trench has a gentle curvature (slope: 35.12°), partially stepped, due to the tectonic movements and faults. The opposite, oceanward side is almost completely leveled. The trench is narrow with maximal depth at the selected segment -3489 m and for the whole dataset -6201 m. The most repetitive depth is in a range -2500 to -2400 m (267 samples) and -2500 to -2600 m (261 samples). The bottom is mostly flat due to the high sedimentation rates indicating the accumulative leveling processes. Marine free-air gravity anomalies along the Cascadia Subduction Zone are characterized by weakly positive values (20 mGal) increasing rapidly in the zone of the continental slope (>200 mGal), which is associated with a decrease in thickness of the Earth’s crust.
Exploring the language layer of thedānastutigenre
Authors: Pinault Georges-Jean 
Published: April 2021

AbstractThe linguistic variedness of the ancient Vedic texts is a well-known fact. This can be observed within theṚgvedaitself, the most ancient collection of hymns, and if one compares the language of theṚgvedawith that of the Atharvaveda. Glimpses of Vedic dialects can be detected in several passages and words, although the poetic language displays a high degree of convention and normalisation. Among the hymns of the Rigveda few specific features can be attributed to the different families of bards, even though one can surmise that they belonged to different regions of the Vedic world. It is also likely that some families or so-called “branches” were linguistically mixed. The hymns resort to different genres of discourse.Thedānastuti, lit. ‘praise of the gift’, marks a distinct part of the poetic competence. The passages in question, which are often limited to a single stanza, although others are more developed, making up a substantial part of the poem, are devoted to praise of the generosity of the patron, who is expected to reward the poet appropriately for his work. A comprehensive survey of these parts of the hymns of the Rigveda was made in the dissertation of Manilal Patel (1929), a student of Karl F. Geldner. This meritorious book describes mostly cultural, historical and ritual features. On the other hand, the familiar, and in cases crude or mischievous, tone of these pieces has been noted by several commentators of the Rigveda. It would be too simple, however, to consider that these parts faithfully reflect everyday speech.The paper aims to explore the linguistic traits of thedānastutis which contrast with the standard layer of the Ṛgvedic language at all levels: phonology, morphology, syntax, vocabulary. On the level of stylistics and poetics, it will be shown that the phraseology of thedānastutis relies on sophisticated devices derived from the standard phraseology which was used otherwise for the praise of the gods and goddesses in the core of the hymns.

Abstract
The article aims to present customer participation in value co-creation based on the demand-side approach to innovation. We present the rationale and principles of the demand-side approach to innovation based on user participation. Further, we discuss the forms of customer engagement in customer-company cooperation, customer motivations, and perceived benefits. This article also identifies the open innovation model’s factors and provides practitioners with implementation guidance regarding the demand approach to innovation. Further, this article shows the influence of the customer’s active role and the demand-side approach to innovation on the enterprise, the economy, and society. Finally, we identify possible risks associated with using this approach and their impact on the environment.

Published: April 2021

Abstract
Good-quality semiorganic single crystals of bis(glycine) strontium dichloride trihydrate (GSC) were grown by slow evaporation technique. The lattice parameters of the grown crystal were verified through single crystal X-ray diffraction. Besides, the crystallinity of the material was analyzed with powder X-ray diffraction. The fingerprint of functional groups of this material was analyzed by FT-IR technique. The UV transparency cutoff wavelength of GSC was found to be 240 nm and the crystal exhibited 80 % transmission in the entire visible region. All intermolecular and intramolecular interactions of the grown crystal were interpreted by Hirshfeld surface analysis, and the strength of the interactions was graphically illustrated by fingerprint graphs. The intramolecular charge transfers of the crystal were assessed through frontier molecular orbital analysis.

Published: April 2021

Abstract
Cellulose nanocrystals were extracted from cotton. The cellulose nanocrystals made a self-assembly structure when dried under slow conditions, as it was revealed by the characterization made to the material. The AFM images of the nanocrystals showed that they had a changing local orientation, pointing in a preferred direction that underwent a periodic change. This periodic change resembles the orientation of a chiral nematic phase. The TEM images showed that the nanocrystals had a rod-like appearance with average length size of 98.5 nm and a diameter of 4.7 nm. The TEM characterization showed the nanocrystals with more details than AFM. In this paper, the self-assembling of CNC was observed by AFM, and further investigations were done by TEM, deconvoluting the process of CNC nanorods aggregation.
Signal Smoothing with Time-Space Fractional Order Model
Authors: Li Yuanlu 
Published: April 2021

Abstract
The time-space fractional-order model (TSFOM) is a generation of the classical diffusion model which is an excellent smoothing method. In this paper, the fractional-order derivative in the model is found to have good performance for peak-preserving. To check the validity and performance of the model, some noisy signals are smoothed by some commonly used smoothing methods and results are compared with those of the proposed model. The comparison result shows that the proposed method outperforms the classical nonlinear diffusion model and some commonly used smoothing methods.
Belonging in Movement: Capoeira for Children and Youth at the Za’atari Refugee Camp
Authors: Hast Susanna 
Published: April 2021

Abstract
This paper examines the practice of using capoeira for psychosocial support at the Za’atari Refugee camp through the work of the Jordanian non-profit organisation Capoeira al-Shababi. It explores the role of body practices involving humour, performance and synchrony on the development of feelings of belonging among Syrian children and youth. The work suggests that the capoeira class succeeded in holding the necessary space for vulnerability, which is the key reason why the participants described a bodily connection with each other and the feeling that the group was a family.
Determination of flavonoids and polyphenols in veterinary products
Authors: Erzsébet Varga , Ibolya Fülöp , Dumitru Croitoru Mircea 
Published: April 2021

Abstract
According to the 8th Hungarian Pharmacopoeia, propylene glycol can be chosen as solvent over ethyl alcohol for use in food supplements, therefore, the concentration of flavonoids and polyphenols in medicinal plants is measured using propylene glycol extracts. Samples of seven products, used in veterinary medicine, known to be rich in polyphenols and flavonoids were chosen to verify the usefulness of propylene glycol as extraction solvent. The polyphenol measurements were carried out using the Folin-Ciocâlteu method and the total flavonoid content was established using the modified method from the 10th Romanian Pharmacopoeia, Cynarae folium monograph. Propylene glycol/water mixture (70%/30%), used as extraction solvent for medicinal plants rich in flavonoids and polyphenols, proved to be useful for extraction of these valuable active substances and correlates with the known amounts stated previously to be present in these vegetable materials. Results were in correlation with literature data, concentrations ranged between 0.05 and 0.07 mg/ml (immediately after preparation), 0.02 and 0.08 mg/ml (within six months following preparation) in case of flavonoids and 2.44 and 3.80 mg/ml (immediately after preparation), 1.20 and 2.18 mg/ml (within six months following preparation) in case of polyphenols.

Abstract
Ventilator-associated pneumonia is a severe nosocomial infection that affects the disease course of critically ill patients. Awareness of potential pathogens is essential for prevention, early detection, and proper treatment, as well.
In this retrospective cross-sectional study, we investigated the tracheal secretions collected from critically ill patients with the aim to detect the occurrence of multidrug-resistant bacteria. We examined the bacteriological culture results of the tracheal secretions of the patients hospitalized at the Intensive Care Unit of Tîrgu Mureș Emergency Clinical County Hospital between 1st November 2017 and 31st January 2018. Admission diagnoses and comorbidities were recorded, and white blood cell counts were monitored. We determined the quality of the lower respiratory samples by microscopic examination and the results of the microbiological tests, taking into account the germ count of pathogens and the antibiotic-resistance pheno-type. During the three months, 194 samples were received from 107 patients for bacteriological examination. After the first sample collection 34 (31.77%) tracheal secretions were positive for pathogens, while in the remaining samples normal upper respiratory bacterial flora was found. From the 34 positive samples, 22 were colonizing pathogens and 30 were isolated in a clinically significant amount. Predominantly Staphylococcus aureus (n=14; 26.9%), Klebsiella pneumoniae (n=9; 17.3%), Escherichia coli (n=8.1%) and other Gram-negative bacteria (n=21; 40.4%) were identified. Among these strains 38 (73.07%) were not multidrug-resistant. The rate of positivity of individual sampling showed a positive correlation with the average duration of hospital stay (p=0.0016; r=0.8740). A total of 26 patients developed early-onset or late-onset ventilator-associated pneumonia. Potential risk factors for infection with multidrug-resistant bacteria were found. We can conclude that recently admitted patients in the intensive care unit are rarely carriers of multidrug-resistant bacteria, but become colonized or infected with multidrug-resistant strains during long-term intensive care.
Bioethics in High School Classes
Authors: Čović Berislav , Marinčić Mile 
Published: April 2021

AbstractWe are witnesses of an attempt to enforce the curriculum reform in Croatia, as well as a proposal of aschool for life.2While the intent of this presentation is not to analyse the curriculum reform, it is important to mention that the curriculum reform, within the framework of the general educational group of subjects, kept the subjects like Ethics and Religion. Unfortunately, some subjects, such as History, Biology or Chemistry could lose their hours in the long run. The reason for bringing this up is simple. It could happen, and this would in no way be good, that within the corpus of teachers a devaluation of certain subjects occurs, as well as animosity among colleagues. When we take a look at the statements of certain politicians3on some subjects (their importance and unimportance), the status of professors etc. we see just how much Croatia needs the constant repetition of the fact that a wholesome, well-rounded, mature individual is not made by brilliance in the STEM area nor excellence in natural sciences, but that very same individual also must strive for excellence and well-roundedness in the cultural, ethical, moral, and any other sense which makes up one of the wheels in the wholesomeness of a person. Any curriculum process, school for life or something of the sort, which would exclude some of the segments in the process of education in terms of the wholesomeness of a human being could only damage society on all levels in the long run.
