Identification of uncertainty levels of acoustic properties of biocomposites under different mounting conditions in impedance tube tests
Authors: Koruk Hasan , Saygili Yusuf , Genc Garip , Sanliturk Kenan Y.
Published: October 2021

Impedance tube method is widely used to measure acoustic properties of materials. Although this method yields reliable acoustic properties for soft textured materials, uncertainty levels of measured acoustic properties for hard materials, including biocomposites, can be quite large,
mainly due to uncertain mounting conditions. Here, the effects of mounting conditions on the acoustic properties of biocomposites in an impedance tube are investigated. First, nominally identical biocomposite samples with a diameter equal to the inner diameter of impedance tube are manufactured
and their acoustic properties are determined. As hard materials practically cause fitting problems in the impedance tube, the diameters of samples are reduced, as in practice, by small amounts and acoustic properties of modified samples are determined. Furthermore, in order to match the diameters
of samples to the inner diameter of impedance tube, different materials such as tape, petroleum jelly and cotton are applied around samples to close the air gap between the samples and the tube's inner wall. All the results are compared, and the uncertainty levels caused by different mounting
conditions on the acoustic properties of biocomposites are identified. The results show that the transmission loss (TL) measurements are dramatically affected by the mounting conditions while the sound absorption conditions are less sensitive to the mounting conditions. The deviations in the
measured TL levels are highest for the samples with tape and wax (10–15 dB). On the other hand, the deviations in the measured sound absorption coefficients are highest for the samples with cotton and tape (1–2%).

A planetáris tudat által megkívánt újfajta gondolkodás, a kreatív energiák alkalmazása, a közös cselekvés, a felelősség érvényesítése, a rugalmasság, sokféleség és a demokrácia érvényesítése nyilvánvalóan a hagyományostól eltérő jogi válaszokat indukál. A lehetséges válaszok között a reziliencia gondolata, eszközkénti alkalmazása egy lehetőség, policentrikus, adaptív rendszereket kialakítva az alkalmazkodás érdekében. Ennek a jogrendszerben is kell legyenek következményei.

Néhány szempont a jólét és a jól-lét gender-aspektusához
Authors: Baluja Petra
Published: October 2021

A tanulmány a nők és férfiak helyzetének kérdését veti fel a jóléti államok kontextusában. Nem célom konkrét politikai intézkedéseket, stratégiákat felvetni, mindössze további adalékokkal szolgálok az egyenlőtlenségi szemlélethez. A jóléti államok kihívásaira adott szakértői válaszok között találhatók a nemek új társadalmi szerződésének igénye is. Ferge és Esping-Andersen állítása szerint a nemek helyzete hatással van az általános jólétre. Ennek alapján azt feltételezem, hogy a nemi egyenlőtlenségek értelmezésében, illetve az új társadalmi szerződés megszületéséhez az objektív és szubjektív jóléti mutatókat együttesen alkalmazó egalitáriánusabb megközelítésre van szükség. Valamint az új társadalompolitikai intézkedések bevezetéséhez érdemes lehet figyelembe venni a nők és férfiak megváltozott élethelyzetét, egyéni tapasztalatát, hogy mitől elégedettek az életükkel. Hazai és nemzetközi felmérések is igazolják, hogy ott nagyobb szintű a nemek közötti egyenlőség, ahol az általános elégedettség magas szintű.
A női szépség megmérettetése
Authors: Fejes Katalin
Published: October 2021

A szépség lehet árucikk, társadalmi rang, hatalom. A szépség fogalma e tanulmányban nem esztétikai vagy filozófiai fogalomként szerepel, hanem a hétköznapok szintjén, a divatszalonok, a próbakisasszonyok, a szépségkirálynők és a leading ladyk világában. A szalonok által tervezett divatos ruhát a csinos, jó alakú manökenek tették vonzóvá, eladhatóvá. Velük szemben a társasági dámák nem a ruhát hangsúlyozták, hanem a ruhák által megteremtett, előnyös megjelenésükkel komoly társadalmi befolyásra tehettek szert. A szépség hatalma társadalmi és történeti kontextustól függ. Visszatetszővé válik egy olyan korszakban, amikor a szépségideált a társadalmi vagy faji kirekesztés politikájának szolgálatába állították.
Concept Map Assessment: An Experimental Mathematical Study
Authors: Šejnoha Jiří , Klavík Pavel
Published: October 2021

In this experimental study, we analyzed the ability to understand and ability to share mathematical knowledge of our modified context maps (MCM) and compared them to the standard linear form of examination. For these purposes, the categorization of mathematical knowledge to local and structural understanding and craft was defined. Experimentation was conducted during the regular final oral exam of Linear algebra courses for computer science freshmen university students. No benefits were given for participation in the experiment.According to the questionnaire self-report student data, the MCM method combined with student-examiner discussion shares statistically significantly better structural understanding than the linear form. However, the MCM method shares less local understanding than the linear form, given randomized data set. Moreover, students claim that the MCM oral examination form is almost as objective as other oral exams they attempted during faculty study. Students created surprisingly good modified cognitive maps, although we assumed their low to none practical experience with concept mapping.

Thyroid carcinosarcoma is a rare and aggressive neoplasm of the thyroid gland, with a recurrent character and a bad prognosis,
despite the introduction of a multimodal treatment that is not yet codied. We present a case of thyroid carcinosarcoma,
number 32 described in the literature, in a 64-year-old man complicating a multinodular goiter that had been evolving for 10 years and which relapsed 6
months after total thyroidectomy. On the anatomopathological level, thyroid sarcoma was mentioned before the microscopic aspect of the tumor and
conrmed by the immune histochemical study. The recurrence was massive requiring the use of tumor reduction surgery that allowed the avoidance of
a tracheotomy and a good locoregional control of the tumor. And yet the patient died of lung metastases 4 months later.

A Robust Predictive Model for Stock Price Forecasting
Authors: Sen Jaydip , Datta Chaudhuri Tamal
Published: October 2021

Prediction of future movement of stock prices has been the subject matter of many research work. On one hand, we have proponents of the Efficient Market Hypothesis who claim that stock prices cannot be predicted accurately. On the other hand, there are propositions that have shown that, if appropriately modelled, stock prices can be predicted fairly accurately. The latter have focused on choice of variables, appropriate functional forms and techniques of forecasting. This work proposes a granular approach to stock price prediction by combining statistical and machine learning methods with some concepts that have been advanced in the literature on technical analysis. The objective of our work is to take 5 minute daily data on stock prices from the National Stock Exchange (NSE) in India and develop a forecasting framework for stock prices. Our contention is that such a granular approach can model the inherent dynamics and can be fine-tuned for immediate forecasting. Six different techniques including three regression-based approaches and three classification-based approaches are applied to model and predict stock price movement of two stocks listed in NSE - Tata Steel and Hero Moto. Extensive results have been provided on the performance of these forecasting techniques for both the stocks.

The shift in shopping methods from physical (offline) stores to virtual (online) stores has crystallized even more. Gradually the shift allows consumers to feel easy and comfortable in respect to buying products by online methods. This earliness paradigm shift becomes interesting if it becomes a topic of the research regarding the possibility of its sustainability in the triple bottom line. The clarity of the consumer's perspective on brand sustainability in terms of the main three pillars is being tested to clarify the roots of the paradigm by becoming a hypothesis in this research. The hypothesis was tested using Structural Equation Modeling on the answers of 278 respondents to identify the significant path. The findings are quite surprising so that entrepreneurs require to put forward the sustainability side of their brand. Future research should be aimed at adding more detailed factors related to the need for the process of achieving sustainability.
Las emociones en los nuevos libros: cuando el libro electrónico captura empáticamente el lector. Una perspectiva educativa
Authors: Bocciolesi Enrico
Published: October 2021

En la sociedad actual son numerosas las evoluciones y los cambios de facto, determinados por la llegada de nuevas tecnologías que, en un contexto social frenético, caótico y líquido (Bauman, 2008), implican a la persona en toda su complejidad. Este cambio y el subsiguiente paso a productos digitales ha producido una transformación del texto escrito y las formas de lectura, así como un cambio en la relación que tenemos con nuestras emociones. Todos nosotros probamos y percibimos las emociones según el contexto, según quien nos acompañe, o según los logros que vayamos cumpliendo. Estas emociones pueden a su vez ser positivas y nobles, como por ejemplo el entusiasmo y el amor, o bien negativas y destructivas, como por ejemplo el aburrimiento y la angustia (Rosati 2006). Este aspecto tiene un carácter global, ya que no concierne sólo a individuos particulares tales como educadores, profesores, e investigadores, sino que afecta a la sociedad en su conjunto, a las formas de comunicar y educar en el seno de la sociedad. En la era de los e-books, el intelecto, y las emociones se enfrentan a la posibilidad de pensar y reflexionar los textos de manera diferente, y también de intervenir sobre el objeto informático con diversos grados de competencia tecnológica y comunicativa.

Biostratigraphical criteria for the recognition of the
Coniacian to Maastrichtian stage boundaries in the Chalk of north-west Europe, with particular
reference to southern England.
Authors: Bailey H. W. , Gale A. S. , Mortimore R. N. , Swiecicki A. , Wood C. J.
Published: October 2021

The biostratigraphical criteria for the recognition of Coniacian to Maastrichtian stage boundaries in the English Chalk, published in the Abstracts to the Copenhagen Symposium on Cretaceous Stage Boundari­es 1983, are reviewed in the light of the discussion at the Symposium and the final recommendations. Particular attention is given to problems relating to the base of the Coniacian and Santonian Stages. A critical assessment is made of criteria used by French workers for recognising the base of the Senonian Stage in the Anglo-Paris Basin. Benthonic Foraminifera used to identify the base of the Senonian are shown to have discrepant ranges in Kent compared with Sussex and Senonian stratotype. The nannofossil Marthasterites furcatus first appears below the level of acme-occurrence of ammonites of the Late Turonian Subprionocyclus neptuni Zone in southern England, and cannot therefore be used as a marker to identify the base of the Coniacian in the Anglo-Paris Basin. Extended comment is made on the bio­stratigraphy of the successions in southern England and northern Germany across the Coniacian - Santonian boundary, and it is suggested that the Upper Coniacian Micraster bucaillei/Gonioteuthis praewestfalica Zone of the German Lligerdorf standard section should be re-assigned to the basal part of the Santonian. The base of the Campanian Stage in southern England is arbitrarily taken at the evolution­ary first appearance of Bolivinoides culverensis, a level coincident with the top of the local Uintacrinus anglicus Zone, rather than at the extinction-level of Marsupites and/or entry of Gonioteuthis granulata­quadrata lower in the succession. The entry of the nannofossil Broinsonia parca, widely taken as a criterion for recognising the base of the Campanian Stage, is shown to occur at an horizon well above the entry-level of B. culverensis.
Proposal for the recognition of boundaries between Cretaceous stages by means of planktonic foraminiferal biostratigraphy
Authors: Marks Peter
Published: October 2021

Planktonic foraminifera are a much used biostratigraphic tool for the subdivision of the Cretaceous System from the Albian upwards. A proposal is given for the recognition of Cretaceous stages, using major biostratigraphic events to mark their boundaries. Thus, the extinction of Globotruncanita calcarata marks the Maastrichtian - Campanian boundary; the extinction of Dicarinel/a asymetrica the Campanian -Santonian boundary; the entry of D. asymetrica the Santonian - Coniacian boundary; the entry of Dicarinella primitiva with Marginotruncana ex gr. renzi -sinuosa the Coniacian -Turonian boundary; the extinction of Rotalipora cushmani the Turonian - Cenomanian boundary; the extinction of Planomalina buxtorfi the Cenomanian - Albian boundary.
Self-assembly of amino acids toward functional biomaterials
Authors: Ren Huan , Wu Lifang , Tan Lina , Bao Yanni , Ma Yuchen , Jin Yong , Zou Qianli
Published: October 2021

Biomolecules, such as proteins and peptides, can be self-assembled. They are widely distributed, easy to obtain, and biocompatible. However, the self-assembly of proteins and peptides has disadvantages, such as difficulty in obtaining high quantities of materials, high cost, polydispersity, and purification limitations. The difficulties in using proteins and peptides as functional materials make it more complicate to arrange assembled nanostructures at both microscopic and macroscopic scales. Amino acids, as the smallest constituent of proteins and the smallest constituent in the bottom-up approach, are the smallest building blocks that can be self-assembled. The self-assembly of single amino acids has the advantages of low synthesis cost, simple modeling, excellent biocompatibility and biodegradability in vivo. In addition, amino acids can be assembled with other components to meet multiple scientific needs. However, using these simple building blocks to design attractive materials remains a challenge due to the simplicity of the amino acids. Most of the review articles about self-assembly focus on large molecules, such as peptides and proteins. The preparation of complicated materials by self-assembly of amino acids has not yet been evaluated. Therefore, it is of great significance to systematically summarize the literature of amino acid self-assembly. This article reviews the recent advances in amino acid self-assembly regarding amino acid self-assembly, functional amino acid self-assembly, amino acid coordination self-assembly, and amino acid regulatory functional molecule self-assembly.

student has a different learning style. Accordingly, foreign language teachers should be aware
of the students’ individual differences in general and learning styles in particular.
This study aims to find out:
1. Iraqi EFL preparatory school students’ learning styles.
2. Iraqi EFL preparatory school students’ level of language proficiency.
3. The correlation between Iraqi EFL preparatory school students’ learning styles and
level of language proficiency.
4. Which of the learning styles do contribute to the interpretation of variation in
language proficiency of Iraqi EFL preparatory school students.
This study is a correlational research in which the population consists of 325 students
from different Iraqi preparatory schools during the academic year 2020/2021. The data is
gathered by employing a questionnaire to assess students' learning styles and an English
language proficiency test to assess students’ proficiency represented by language skills. After
their validity and reliability are verified, the instruments are applied to the research sample.
The results of the statistical manipulation showed the following:
1. Iraqi EFL preparatory school students show weak level of language proficiency.
2. The dominant learning styles of Iraqi preparatory school students are random/intuitive
style, followed by impulsive/reflective, while the sequential learning style comes
third. While the use of closure/open oriented and deductive/inductive learning styles
are not statistically significant.
3. Iraqi EFL preparatory school students’ learning styles are statistically correlated with
their English language proficiency.
4. The visual, auditory, impulsive/reflective, and synthetic/analytic styles contribut

Published: October 2021

Summary. Diabetes mellitus (DM) is a risk factor for severe bacterial keratitis, which often leads to complications.

The aim was to identify the features of the dynamics of the I degree of severity bacterial keratitis in diabetic patients.

Materials and methods. The results of treatment of 15 patients with type 1 DM and bacterial keratitis of the I degree of severity (main group) and 20 patients with bacterial keratitis of the I degree of severity without DM (control group) were analyzed. The severity of bacterial keratitis was determined according to our proposed scheme with a total score of ≤ 14. All patients were treated with instillations of ofloxacin, antiseptics, antioxidants, reparents, artificial tears, mydriatics, systemic anti-inflammatory therapy. In addition to standard, ophthalmic examination methods included bacteriological examination, fluorescein test, OCT of the anterior segment of the eye, non-contact corneal esthesiometry.

Results and discussion. In diabetic patients with bacterial keratitis of the I degree of severity the degree of inflammatory reaction in the anterior chamber of the eye and the average threshold of corneal sensitivity at all airflow temperatures at the first visit exceeded the indicators of controls (p<0.05). The degree of the average corneal sensitivity threshold decrease throughout the observation, the degree of pericorneal injection, the size of the corneal ulcer, the depth of corneal infiltration from the 3rd day of observation, the depth of corneal ulcer and corneal edema from the 7th day exceeded indicators of controls (p<0.05).

Conclusions. Diabetic patients have features of the dynamics of the I degree of severity bacterial keratitis, which lead to prolongation of the disease and worsening of its consequences.

Summary. Objective: To improve the results of treatment of patients with stage II-III hemorrhoids using the wireless Doppler surgical complex Trilogy HAL-RAR Unit.

Materials and methods. In the clinic of coloproctology of the Military Medical Clinical Center of the Southern region of Odessa according to the method of disarterization of hemorrhoidal arteries and recto-anal recovery using wireless Doppler surgical complex Wi-3 Trilogy HAL-RAR for the period from January 2019. to June 2020 19 patients were operated on.

Results and discussion. In the postoperative period, moderate pain was observed for three days in 13 patients (68.4 %), only one of them had pain for the first 6 days after surgery. In 6 (31.6 %) patients no complaints of pain in the postoperative area were noted. In all patients, the pain was acquired by taking nonspecific anti-inflammatory drugs without the use of narcotic analgesics. In the postoperative period, patients were examined for 2, 7 and 90 days after surgery. No complications were noted in the postoperative period. In 4 (20 %) patients, due to the presence of enlarged hemorrhoids, the operation was extended by removing the external hemorrhoids and suturing the mucosal defect. All patients noted no reduction in quality of life in the postoperative period.

Conclusions. Surgical treatment of hemorrhoids using Trilogy HAL-RAR technology is a minimally invasive method that reduces the patient’s stay in the hospital in the postoperative period, does not require the use of narcotic analgesics, promotes rapid recovery and may be the surgery of choice for surgical treatment of hemorrhoids II-III.

Summary. Aim. Comparison of methods for diagnosis of hepatic encephalopathy in patients with cirrhosis.

Matherials and Methods. We observed 95 patients with LC who were hospitalized from 2018 to 2020 in the Department of Anesthesiology and Intensive Care, Surgical and Gastroenterological Departments of the Transcarpathian Regional Clinical Hospital. Andriy Novak (Uzhhorod). Neurological status, state of mental and cognitive functions in patients with LC were assessed before and after the course of therapy with psychometric testing, as well as electroencephalographic (EEG) study. The severity of LE was determined by West-Haven criteria.

Results. Signs of LE were not diagnosed in 8.4 % of patients with LC. In 13.8 % of patients found a latent form of LE. This was most often observed in the III century. (in 25.2 % of patients), LE II. diagnosed in 22.1 % of patients with LE and Art. — in 17.9 % of examined patients, and in 12.6 % of examined — LE IV. In patients with LC, alpha waves on the EEG are most often registered in the latent form of LE, and with the increase of clinical signs of LE there is a decrease in the frequency of alpha waves, instead of pathological delta and theta waves.

Conclusions. According to the MMSE scale, the highest scores are observed in patients of group I (29.9 ± 3.4). The most pronounced disorders of intelligence were determined in patients with LC of group III from the IV century. LE (15.1 ± 3.3). The level of personal anxiety in patients with LC was higher than normal in patients with LE II-IV centuries. surveyed groups with maximum values in group III (55.5 ± 8.2). At patients with LC the expressed cognitive frustration are observed. Signs of LE were not diagnosed in 8.4 % of patients with LC. In 13.8 % of patients found a latent form of LE. This is most often observed in the III century. (in 25.2 % of patients), LE II. diagnosed in 22.1 % of patients with LE and Art. — in 17.9 % of examined patients, and in 12.6 % of examined — LE IV.

Summary. The aim of the work is to improve the results of surgical treatment of iatrogenic injuries of the extrahepatic bile ducts.

Materials and methods. The experience of treating 362 patients with iatrogenic injuries of the extrahepatic bile ducts, obtained mainly in other hospitals over the past 18 years, is presented. In the clinic, these patients are reoperated. Among them were 258 (71.3 %) women and 104 (28,7 %) men aged 20 to 80 years.

Results and discussion.Damage and stricture of the bile duct were noted during laparotomic (299) and laparoscopic (63) cholecystectomy. Damage to the hepatic duct was seen in 235 patients, choledochus — in 127. The main research methods were: percutaneous transhepatic cholangiography, endoscopic retrograde cholangiopancreatography, fistulocholangiography. In the clinic, all 362 patients were operated. In 47 of them were performed restorative operations, and in 315 of them were performed reconstructive ones. At the first stage (until 2004), restorative and reconstructive operations (with transhepatic frame drainage) were used more often. At the 2nd stage (since 2005), the operation of choice was a high hepaticoduodenostomy in 2 modified versions. Over the past 7 years, the number of postoperative complications has been reduced by 8,3 %, mortality from 6,8 to 1,5 %.

Conclusions. The operation of choice in case of complete damage to the bile duct is the formation of a high hepaticojejunoanastomosis according to our modified methods. Reconstructive operations are indicated only in case of partial damage to the bile duct. A multidisciplinary approach to the correction of duct damage is advisable, which should be carried out in specialized surgical hepatological centers. The use of modified methods of reconstructive surgery contributed to a decrease in postoperative complications by 8,3 % and mortality by 5,3 % (95 % CI, p <0.05).

Published: October 2021

Summary. Introduction. Despite the introduction of modern methods of diagnosis, tactics, and treatment of diseases of the abdominal organs, the risk of developing early postoperative complications remains high.

The aim of this study is to clarify the causes of early postoperative complications and indications for their surgical treatment.

Materials and methods. 3947 case histories of patients operated on for urgent indications were analyzed. In 73 cases, relaparotomies were performed in the early postoperative period (1.85 %).

Results and discussion. The main nosologic unit, during the surgical treatment of which relaparotomies were performed, was acute appendicitis. Then there was a perforated pyloroduodenal ulcer and a strangulated hernia of various localization. The main indications for relaparotomy were progressive peritonitis, early adhesive intestinal obstruction, intra-abdominal abscesses, and infiltrates. In two cases, no pathology was detected during relaparotomy – there was an over diagnosis of postoperative peritonitis and anastomotic suture failure.

Conclusion. 1. The main cause for relaparotomies in urgent surgery is the progression of preoperative peritonitis. 2. The second important cause is early postoperative adhesive intestinal obstruction. 3. Errors in intraoperative diagnostics, tactics, and techniques are the third leading cause of early relaparotomies.

Summary. Purpose of the work. To study the structure of the pathogenic flora in pneumoempyema and its sensitivity to antibacterial agents. Materials and methods. It were examined 159 patients of both sexes, with pneumoempyema. We detected the species of microflora, and its sensitivity to antibacterial agents. The material for bacteriological studies was pleural exudates, wich we obtained from the pleural cavity by the puncture method. Research results. The characteristic of the pleurals flora has been revealed, the sensitivity of these pathogens to antibacterial drugs has also been detected. We have made antibacterial therapy schemes for patients with pneumoempyema. Conclusions. In the etiology of pneumoempyema predominate next gram-positive bacteria: Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus, which were sensitive to inhibitor-protected penicillins, and 4th generation cephalosporins. Gram-negative flora was represented by Pseudomonada aerugenosa, Escherichia Coli, Enterobacter spp., which were sensitive to fluorchinolones of III and IV generations and carbapenems. We have proposed schemes of antibacterial therapy: A. Initial therapy: 4th generation cephalosporin + 3th–4th generation fluoroquinolone. B. Reserve scheme: inhibitor-protected penicillin + carbapenems. These combinations are most effective against 96.0 % of microorganisms identified by us. In case of prescribing two or more antibacterial agents, as well as with antibacterial therapy for seven days or more, antifungal agents should be prescribed.
