NEW IMAGE OF SLOVENIAN VETERINARY RESEARCH WITH ASCLEPIUS’ SYMBOL
Authors: Cestnik Vojteh
Published: July 2023

In the sixtieth year of continuous publishing, the cover page of Slovenian Veterinary Research features the symbol of veterinary medicine that we have been missing until now. It is the rod of Asclepius (Greek) or Aesculapius (Latin) wrapped by a snake, both of which are surrounded by a capital letter V. The symbol or attribute of the Asclepius’ rod with a snake originates from Antiquity and was used in our profession after it accepted scientifically based principles of work and became to be called veterinary medicine. There are several explanations about the origin and source of the symbol, a slightly deeper reflexion takes us among the legends and myths of Antiquity, which are however, by no means as beautiful as the ones we read in our youth in the collection of The Most Beautiful Legends of Classical Antiquity by Gustav Benjamin Schwab (1792–1850), edited in German language (Die schönsten Sagen des klassischen Altertums) in the years 1838 and 1840.
NOVA PODOBA SLOVENSKEGA VETERINARSKEGA ZBORNIKA Z ASKLEPIJEVIM SIMBOLOM
V šestdesetem letu neprekinjenega izhajanja na naslovnico Slovenskega veterinarskega zbornika prihaja znak veterinarske medicine, ki smo ga do sedaj pogrešali. To je Asklepijeva (gr.) ali Eskulapova (lat.) palica, ki jo ovija kača, obe pa obdaja velika črka V. Simbol ali atribut Asklepijeve palice s kačo izvira iz antike. V naši stroki se je pričel uporabljati potem, ko je ta prevzela znanstveno utemeljena načela dela in se pričela poimenovati veterinarska medicina. O izvoru in nastanku simbola je več razlag. Nekoliko poglobljeno premišljevanje nas popelje v svet simbolike in antičnih mitov, ki nikakor niso tako lepi, kot smo jih v mladosti brali v zbirki Najlepše antične pripovedke Gustava Benjamina Schwaba (1792–1850), ki so v nemščini (Die schönsten Sagen des klassischen Altertums) izšle v letih 1838–1840.

Методом компьютерного моделирования исследованы особенности самовоспламенения богатых смесей метана с кислородом в широком диапазоне начальных температур, давлений и значений коэффициента избытка горючего ϕ в условиях проточного реактора идеального вытеснения и статического реактора (бомбы постоянного объема). Для обоих типов реакторов показано наличие области отрицательного температурного коэффициента (ОТК) скорости реакции в широком диапазоне значений коэффициента избытка горючего ϕ и давлений. Эта область отчетливо видна как на температурной зависимости времени задержки самовоспламенения, так и на температурной зависимости максимальной скорости тепловыделения. Рассмотрен механизм возникновения области ОТК при окислении метана. Поскольку для окисления метана в литературе описаны два механизма возникновения этого явления, можно было ожидать появления двух областей ОТК, что не наблюдалось. Видимо, оба механизма действуют в одном температурном интервале, поэтому не являются независимыми и при изменении условий имеет место плавный переход от одного механизма к другому. Были проанализированы выход продуктов окисления метана и влияние давления на его самовоспламенение.

В период с 2019 по 2022 гг. на Международной космической станции (МКС) проводился совместный российско-американский космический эксперимент (КЭ) Flame Design (Адамант). Цель совместного КЭ - изучение механизмов управления сажеобразованием в сферическом диффузионном пламени (СДП), формируемом вокруг пористой сферы (ПС), и радиационного погасания СДП в условиях микрогравитации. Объектами исследования были «нормальные» и «обратные» СДП газообразного этилена в атмосфере кислорода с добавками азота при комнатной температуре и давлениях от 0,5 до 2 атм.«Нормальное» пламя - это пламя, образованное в атмосфере окислителя при подаче горючего через ПС.«Обратное» пламя - это пламя, образованное в атмосфере горючего при подаче окислителя через ПС. В статье представлены результаты расчетов сажеобразования в нормальных и обратных пламенах. Расчеты основаны на одномерной нестационарной модели диффузионного горения газов с детальной кинетикой окисления этилена, дополненной макрокинетическим механизмом сажеобразования. Показано, что сажеобразование в нормальных и обратных пламенах сосредоточено в области, где местное атомарное отношение C/O и местная температура удовлетворяют условиям 0,32 < C/O < 0,44 и T > 1300-1500 К.

Published: July 2023

Numerical simulation of continuously rotating detonations (CRD) of stoichiometric two-fuel mixture with air has been carried out for the cylindrical annular detonation chamber (DC) of the rocket-type engine. Thesyngas (1 - α)óO + αH2, a binary mixture of hydrogen H2 and carbon monoxide CO, is taken as a fuel. The global flow structure in the DC and the detailed structure of the transverse detonation wave (TDW) front in thecontinuously rotating regime have been studied. Integral characteristics of the detonation process - the distribution of average values of static and total pressure along the length of the DC - and the value of specific impulse on the DC exit have been obtained. The regions of existence of stable CRD regime in coordinates “stagnation pressure pm - stagnation temperature Tm” in the injection manifold (receiver) have been determined. The minimal values of the DC length and radius for CRD for some regions at the pm-Tm plane have been found.

Exploring age differences in absorption and enjoyment during story listening
Authors: Mathiesen Signe Lund , Van Hedger Stephen Charles , Irsik Vanessa C. , Bain Matthew , Johnsrude Ingrid , Herrmann Bjorn
Published: July 2023

Using naturalistic spoken narratives to investigate speech processes and comprehension is becoming increasingly popular in experimental hearing research. Yet, little is known about how individuals engage with spoken story materials, and how listening experiences change with age. We investigated absorption in the context of listening to spoken stories, explored predictive factors for engagement, and examined the utility of a scale developed for written narratives to assess absorption for auditory materials. Adults aged 20-78 years (N = 216) participated in an online experimental study. Participants listened to one of ten stories intended to be engaging to different degrees and rated the story in terms of absorption and enjoyment. Participants of different ages rated the stories similarly absorbing and enjoyable. Further, higher mood scores predicted higher absorption and enjoyment ratings. Factor analysis showed scale items approximately grouping according to the original scale dimensions, suggesting that absorption and enjoyment experiences may be similar for written and spoken stories, although certain items discriminated less effectively between stories intended to be more or less engaging. The present study provides novel insights into how adults of different ages engage in listening and supports the use of naturalistic speech stimuli in the context of hearing research.

Published: July 2023

Background and Objective: The goal of this study was to analyze the association of brain arteriovenous malformations (AVMs) location and its outcome after microsurgical excision. The relation of outcome using modified Ranklin Scale (mRS) at time of discharge, early and last follow ups with respect to location of AVM.
Methods: Demographic data, AVM characteristics, and treatment outcomes were evaluated in 47 bAVMs treated with microsurgery between November 2009 and April 2021. For this series, 47 patients were retrospectively reviewed. The mRS was used to assess functional outcome post-surgery with respect to its location
Outcomes: Forty-seven patients (32% female) and 68% male; average age 33.4 years) with brain AVMs were included in this review. Among the AVMs, the mean size was 5.5cm, 83% with hemorrhage, 63% with deep drainage, mean SM grade is 2.74. The non-eloquent AVM comprised of 25.5%. The most common eloquent location was language (36.2%), followed by sensorimotor (23.4%), visual 8.5% and coordination 6.4%. Motor mapping was done in all cases of brain AVM with sensorimotor eloquence. There was no statically significant difference in the baseline patient and AVM characteristics among different subtypes of eloquence. Favorable outcome (mRS 0-2) was seen on both eloquent (100% in visual) and non-eloquent AVMs. Age and AVM size were significant predictor for good overall outcome in last follow-up.
Conclusion: Although the sample size of this study is a limitation, the result of our case series demonstrated excellent surgical outcome for visual eloquence, good outcome in sensorimotor and language eloquence. Coordination eloquence had worse overall outcome.

Published: July 2023

A healthy diet is the key to longevity, increasing the body's resistance to adverse environmental influences, and is a prerequisite for quality of life. One of the problems that humanity must solve today is the search for non-traditional protein sources and their popularisation in the food market as a healthy alternative to meat protein, which is the most popular. Nowadays, vegetarianism is the most widespread system of health-improving nutrition. According to this system, meat products (pork, beef) are replaced from the daily diet and other sources of amino acids take their place. The relevance of the study is related to the need to develop minced semi-finished products suited for consumption by a wide range of consumers, including those who adhere to vegetarian and vegan diets. The main goal of the study was to achieve the nutritional value of the protein component of minced meat compared to beef-based minced meat. The following research methods were used to solve these tasks: the organoleptic assessment considered: appearance, colour, cutaway view, smell, taste; moisture content – by drying the sample to a constant weight; fat content – by Soxhlet method; protein content – by Kjeldahl method; amino acid composition – by liquid chromatography, fatty acid composition – by gas-liquid chromatography. The main ingredient with protein content in minced meat is protein-wheat texture, which contains a balanced set of amino acids. The study of the amino acid composition of meatless minced semi-finished products has shown that this product is a valuable source of all essential amino acids. Cutlets are characterized by a significant content of valine, methionine, and phenylalanine. The finished product meets the requirements of the current regulatory documentation and does not pose a microbiological danger to the consumer. Therefore, the development of a new semi-finished product technology, which is a meatless minced meat composition that meets the requirements of a healthy diet in terms of protein and fat composition, is one of the ways to solve the problem of introducing food products recommended for vegetarians

CFD Simulation of Air Flow Patterns in a Spray Dryer Fitted With a Rotary Disk
Authors: Saleh Saad Nahi , Hameed Laith Amjad
Published: July 2023

The air flow pattern in a co-current pilot plant spray dryer fitted with a rotary disk atomizer was determined experimentally and modelled numerically using Computational Fluid Dynamics (CFD) (ANSYS Fluent ) software. The CFD simulation used a three dimensions system, Reynolds-Average Navier-Stokes equations (RANS), closed via the RNG k −ε turbulence model. Measurements were carried out at a rotation of the atomizer (3000 rpm) and when there is no rotation using a drying air at 25 oC and  air velocity at the inlet of  5 m/s without swirl. The air flow pattern was predicted experimentally using cotton tufts and digital anemometer. The CFD simulation predicted a downward central flowing air core surrounded by a slow recirculation zones near the walls for both conditions. Analysis of CFD simulation revealed that rotation of atomizer resulted in a swirling motion of the central air core. Simulations results were in good agreement with experimental data.

BACKGROUND: The employment rates of autistic young adults continue to be significantly lower than that of their neurotypical peers. OBJECTIVE: Researchers in this study sought to identify the barriers and facilitators associated with these individuals’ transition into the workforce to better understand how educators and stakeholders can support students’ post-secondary career plans. METHODS: Investigators used a classification tree analysis with a sample of 236 caregivers of autistic individuals, who completed an online survey. RESULTS: The analysis identified critical factors in predicting successful employment for respondents 21 years and under and those over 21 years old. These factors included: difficulties in the job search process, challenges with relationships at work, resources used, job maintenance, motivation to work, and the application process. CONCLUSION: These findings represent the first use of machine learning to identify pivotal points on the path to employment for autistic individuals. This information will better prepare school-based professionals and other stakeholders to support their students in attaining and maintaining employment, a critical aspect of achieving fulfillment and independence. Future research should consider the perspectives of other stakeholders, autistic individuals and employers, and apply the findings to the development of interventions.

Background: The implementation of new adaptations during the Covid 19 pandemic has led to an increase in the use of online applications as a means of Communication, Information and Education, one of them is the zoom cloud meeting application, this application is widely used in educational settings but is rarely used in implementing health education in the community, especially in increasing knowledes of the prehypertensive adult group.This  study  aims  to  identify  the  effectiveness  of  online health education  in improving knowledge about how to manage prehypertension. Methods: The method used is a quasi-experimental with a control group of 70 respondents who were selected by purposive sampling. The intervention and control groups each amounted to 35 respondents. Health education online using zoom cloud meeting was given to the intervention group for ± 40 minutes (three times a week). Results: The results of this study indicated that there was an effect of online health education using zoom cloud meeting in improving knowledge about prehypertension management (p- value 0.001). Conclusion: In conclusion, online health education using zoom cloud meeting was effective in improving the knowledge about prehypertension management toward adults with prehypertension. Online health education using zoom cloud meeting can improve knowledge therefore it can be aplicated in community setting to improve knowledge about health management.

Quantitative Aeroelastic Stability Prediction of Wings Exhibiting Nonlinear Restoring Forces
Authors: TAMER Aykut
Published: July 2023

In engineering practice, eigen-solution is used to assess the stability of linear dynamical systems. However, the linearity assumption in dynamical systems sometimes implies simplifications, particularly when strong nonlinearities exist. In this case, eigen-analysis requires linerisation of the problem and hence fails to provide a direct stability estimation. For this reason, a more reliable tool should be implemented to predict nonlinear phenomena such as chaos or limit cycle oscillations. One method to overcome this difficulty is the Lyapunov Characteristic Exponents (LCEs), which provide quantitative indications of the stability characteristics of dynamical systems governed by nonlinear time-dependent differential equations. Stability prediction using Lyapunov Characteristic Exponents is compatible with the eigen-solution when the problem is linear. Moreover, LCE estimations do not need a steady or equilibrium solution and they can be calculated as the system response evolves in time. Hence, they provide a generalization of traditional stability analysis using eigenvalues. These properties of Lyapunov Exponents are very useful in aeroelastic problems possessing nonlinear characteristics, which may significantly alter the aeroelastic characteristics, and result in chaotic and limit cycle behaviour. A very common nonlinearity in flexible systems is the nonlinear restoring force such as cubic stiffness, which would substantially benefit from using LCEs in stability assessment. This work presents the quantitative evaluation of aeroelastic stability indicators in the presence of nonlinear restoring force. The method is demonstrated on a two-dimensional aeroelastic problem by comparing the system behaviour and estimated Lyapunov Exponents.

Relapse is a highly burdensome phenomenon in mental health care as it creates distress not only in the individual but also in the family and society. Therefore, detecting factors that are potential to develop relapse and the management measures for a psychiatric patient after relapse are very much important. The study was carried out to know whether different types of psychiatric patients were experiencing relapse due to the outbreak of the COVID-19 pandemic. A survey with telephonic interviews was conducted with 55 mental health professionals of Bangladesh. A total of 250 psychiatric patients’ information was collected. It was found that 56.40% of them relapsed after outbreak of the COVID-19 and most of them were females and young adult patients. Patients reported of suffering from anxiety disorders, depressive disorders, and obsessive-compulsive disorders before the COVID-19 relapsed more than the other disorders. The most reported causes of their relapse were fear of having COVID-19, feeling frightened and anxious due to uncertainty in the COVID-19 situation, feeling depressed due to social isolation and adjustment problems, and conflicts with family members. Relapsed patients had taken services mostly through telemedicine and tele-counseling rather than face-to-face services. Recommendations to the management of relapse of psychiatric patients in a pandemic based on the results of the study are discussed.

Serhiy Eisensteinʹs Filmmaking in the Context of Japanese Visual and Performative Practices.
Authors:   Kharkiv State Academy of Culture, Rybalko Svitlana
Published: July 2023

The article examines creative techniques of the outstanding film director Serhiy Eisenstein in the context of Japanese visual and performative practices. In particular, a range of sources that formed Eisenstein’s idea of the Japanese artistic experience is identified. They include works of Japanese art, hieroglyphics, scientific literature, kabuki theatrical performances and communication with the bearers of Japanese theatrical tradition. A variety of borrowings of creative techniques of Japanese artists and their creative interpretation is revealed on the basis of a comparative analysis of Japanese visual and performative practices with the materials of theoretical and creative heritage of the artist and memoirs. Pre-drawn compositions of frames (so called “sketches”) reveal the techniques of Japanese engraving, samples of which were stored in the directorʹs own collection: close up compositions, sharp camera angles and perspective cuts, expressive silhouettes, shadow play, forming a second meaningful plan. Close ups in the film Ivan the Terrible contain many parallels with such techniques of Kabuki Theater as grotesque facial expressions, mimic facial wrinkles, apples of the eyes extremely slanted to the side, or brought to the bridge of the nose. The models of expression of various emotional states honed in the theatrical practice of Japan corresponded to Eisenstein’s idea of cinema “types”. The principles of using sound as one of the means of expression in the performance of kabuki prompted the director to develop the concept of editing as the main means of developing an audiovisual work. It is established that Eisensteinʹs research of various branches of Japanese art, his experience in the study of hieroglyphic writing directed the masterʹs creative experiments in search of metaphorical language, the principles of developing a clear, easy to read visual component.

Inherited retinal dystrophies (IRDs) are a clinically and genetically heterogeneous group of disorders that often severely impair vision. Some patients manifest poor central vision as the first symptom due to cone-dysfunction, which is consistent with cone dystrophy (COD), Stargardt disease (STGD), or macular dystrophy (MD) among others. Here, we aimed to identify the genetic cause of autosomal dominant COD in one family. WGS was performed in 3 affected and 1 unaffected individual using the TruSeq Nano DNA library kit and the NovaSeq 6,000 platform (Illumina). Data analysis identified a novel spliceogenic variant (c.283 + 1G>A) in the thyroid hormone receptor beta gene (THRB) as the candidate disease-associated variant. Further genetic analysis revealed the presence of the same heterozygous variant segregating in two additional unrelated dominant pedigrees including 9 affected individuals with a diagnosis of COD (1), STGD (4), MD (3) and unclear phenotype (1). THRB has been previously reported as a causal gene for autosomal dominant and recessive thyroid hormone resistance syndrome beta (RTHβ); however, none of the IRD patients exhibited RTHβ. Genotype-phenotype correlations showed that RTHβ can be caused by both truncating and missense variants, which are mainly located at the 3′ (C-terminal/ligand-binding) region, which is common to both THRB isoforms (TRβ1 and TRβ2). In contrast, the c.283 + 1G>A variant is predicted to disrupt a splice site in the 5′-region of the gene that encodes the N-terminal domain of the TRβ1 isoform protein, leaving the TRβ2 isoform intact, which would explain the phenotypic variability observed between RTHβ and IRD patients. Interestingly, although monochromacy or cone response alterations have already been described in a few RTHβ patients, herein we report the first genetic association between a pathogenic variant in THRB and non-syndromic IRDs. We thereby expand the phenotype of THRB pathogenic variants including COD, STGD, or MD as the main clinical manifestation, which also reflects the extraordinary complexity of retinal functions mediated by the different THRB isoforms.
Updated geostrophic circulation and volume transport from satellite data in the Southern Ocean

Published: July 2023

Introduction: A geodetic estimation of the surface geostrophic currents can be obtained from satellite data by combining sea surface height measurements obtained from altimetry missions with geoid data from gravity missions. These surface geostrophic currents serve as a reference for inferring a comprehensive three-dimensional (3D) geostrophy by propagating them downwards using temperature and salinity profiles.

Methods: In this work, we revisit this problem for the Southern Ocean, estimating the 3D geostrophy near full depth in 41 layers, with a 1° spatial resolution and monthly temporal resolution, covering the 12 years from 2004 to 2015. We analyze the obtained 3D geostrophy over the Southern Ocean region, where the Antarctic Circumpolar Current (ACC) and its several fronts are depicted, as well as other major currents such as the Agulhas Current, the Brazil-Malvinas Current, or the East Australian Current. From the 3D geostrophic currents, we also estimate the associated water volume transport (VT) and present the results for the ACC and the Drake Passage in the context of existing literature.

Results: Our analysis yields a mean VT estimate of 15.9 ± 0.1 Sv per 1° cell within the ACC region and 149.2 ± 2.2 Sv for the Drake Passage ([60.5°S, 54.5°S] x [303.5°E]). Importantly, our study includes a comprehensive validation of the results. The spatial resolution of our space-data-based approach enables us to provide VT estimates for various paths followed in the different in situ campaigns at the Drake Passage, thereby validating our findings.

Discussion: The analysis demonstrates a remarkable agreement across different measurement locations, reconciling the differences in estimates reported from different campaigns. Moreover, we have estimated the barotropic and baroclinic components of the currents and their associated VT.
