Intertextuality of Yevgen Pluzhnyk's Poetic Legacy
Authors: BILICHAK Oksana , OSMAK Nina , BYKOVA Tetyana , SHEVEL Natalia
Published: September 2021

For understanding Y. Pluzhnyk’s poetry in the context of modern discourse, it is valuable to study the content of his lyrics in light of intertextual connections, which are presented in the article at the formal and semantic levels. It was determined that different intertextual forms reveal a functional dependence on the purpose underlying their introduction into the text by Y. Pluzhnyk (the illustrative charge, contrast, tho­ught reinforcement, delimiting observation, accumulation, etc.). The active use of various folkloric, mythological, artistic, and philosophical reminiscences transmits a distinctive repulsion from a known pattern for the sake of a new creative result. The presence of different intertextual types is a unique marker for the semantics embedded within Pluzhnyk’s text, which forms a circle that intertwines moods, worldview, and the author’s philosophy.

Hospitality as Care for the Other
Authors: KOLINKO Marina , DODONOV Roman , DODONOVA Vira
Published: September 2021

The article aims to study the phenomenon and theoretical concept of hospitality in historical, cultural and socio-philosophical contexts. It has been proved that hospitality is an actual strategy of attitude to the Other. Hospitality has been defined as an interaction with the Other, attitude to the Other as a guest. The essential features of hospitality, its transformation from traditional forms to modern dimensions, mechanisms of implementation of the abstract law of hospitality in contemporary social practices have been analyzed. It is emphasized that hospitality acts as a universal norm and form of coexistence of people, interaction of different cultures, nations, ethnic groups. The potential of dialogicity and tolerance inherent in hospitality, which is interpreted as protection and assistance to humans in a changing global world, the foundation of understanding the Other have been revealed. Hospitable interaction is not limited to the socio-cultural experience of interpersonal relations but is shown as an acceptable model that introduces the principle of consent in intercultural relations in the field of migration, tourist exchanges and other social processes.

Revisiting Term Studies in Modern Poly-Cultural and Poly-Lingual Contexts: Methadological Approach
Authors: CHAIKA Oksana , SAVYTSKA Іnna , SHARMANOVA Natalia
Published: September 2021

The analysis of the issues in term studies showcases that the scholars’ attempts to come to the unified approach to the definition of the term has not been successful yet. No longer is the academic world seen as numbers of regional scientific schools across geographies. On the contrary, globalisation has significantly affected academia and the respective product of science. The subject matter of the research links to poly-culturalism and poly-lingual communication in the contemporary world of science. It aims at the description of monomial and polynomial – proposed substitutes for set (irreversible) term expressions in languages for specific purposes when digitized. It is suggested that an interdisciplinary dialogue between linguistics in Saussure’s concept and philosophy, psychology, neuroscience, and computer science would ultimately make the world catch up with ICT in the digital era. Robotics, automation of processes are soon to absorb vast domains of specialized knowledge. As formal and logical treatment of language helps employ algebraic tools for linguistic analysis, comparative analysis between terms in terminology and an algebraic expression evidences similarities that may hardly be ignored. Thus, an algorithmic description of terminology could generate an infinite number of products from a finite number of essential elements.

Common-Sense Rejected by Physicists:
Authors: Boyd Jeffrey
Published: September 2021

We propose a new integration of relativity and quantum mechanics (QM). Your cell phone or smart phone is a rich source of empirical information about relativity. It tells time based on a system called Coordinated Universal Time (UTC) which assumes absolute simultaneity: all observers in all inertial frames observe the same sequence of all events. You must choose whether to trust the time on your cell phone, or trust Einstein’s incompatible ideas about a space-time continuum. As concerns QM, the existence of “weirdness” means a mistake was made in QM’s starting assumptions. This article finds and corrects that mistake and presents for the first time, a quantum world free of all weirdness. There is another half to nature, previously unrecognized. It is devoid of energy and matter, namely zero-energy Elementary Waves which move within the medium of aether. We derive the linear wave PDE’s. There is evidence that Elementary Waves are in control of nature, despite their lack of energy. The existence of UFO’s (Unidentified Flying Objects) suggests that someone has learned how to control Elementary Waves. If we could learn from the UFO’s, we might acquire a decisive advantage in our battle against climate change.
Which Message? Which Channel? Which Customer? - Exploring Response Rates in Multi-Channel Marketing Using Short-Form Advertising
Authors: Marzouk Omar , Salminen Joni , Zhang Pengyi , Jansen Bernard J.
Published: September 2021

Formulating short-form advertising messages with little ad content that work and choosing high-performing channels to disseminate them are persistent challenges in multichannel marketing. Drawing on the persuasive systems design (PSD) model, we experimented with 33,848 actual customers of an international telecom company. In a real-life setting, we compared the effectiveness of three persuasion strategies (rational, emotional, and social) tested in three marketing channels (short message service (SMS), social media advertising, and mobile application), evaluating their effect on influencing customers to purchase international mobile phone credits. Results suggest that companies should send rational messages when using short-form advertising messages regardless of the channel to achieve higher response rates. Findings further show that certain customer characteristics are predictive of positive responses and differ by channel but not by message type. Findings from crowdsourced evaluations also indicate that people noticeably disagree on what persuasive strategy was applied to these short messages, indicating that consumers are not well-equipped to identify persuasive strategies or that what advertisers see as a “pure” strategy actually involves elements from multiple strategies as interpreted by consumers. The results have implications for the theoretical understanding of persuasive short-form commercial messaging in multichannel marketing and practical insights for advertising within a limited amount of space and attention afforded by many digital channels.
Interactional integration of talk and note-taking
Authors: Nielsen Søren Beck
Published: September 2021

This paper contributes to the current line of research that examines how participants interactionally engage in simultaneous multiple courses of actions. It looks into how institutional interactants jointly integrate two concurrent engagements: talk and note-taking. It builds upon video recordings of naturally occurring monitoring visits in Denmark, where social supervision representatives interview foster parents and facility leaders and simultaneously take notes on their laptop computers. Data suggest that talk and note-taking concur very commonly, that is, representatives take notes extensively while the other party talks. The paper investigates three factors that advance our knowledge about interactional reasons why this dual engagement can take place so commonly. First, when initiating concurring writing or talk, both parties orient towards simultaneous engagement in the two activities as appropriate. Second, whilst writing, representatives verbally display recipiency to talk, which prompt speakers to continue. Third, representatives frequently suspend the act of writing in order to briefly face the speakers, which they similarly treat as an encouragement to continue.

Sedimentation technology was selected but provided that a filter element should be present in the installation. The article describes the types of industrial sedimentation tanks used more often. In condition that the system should be compact, while at the same time the purification efficiency rate should be high, the new suitable design of the water treatment system was developed.
Variation and Evolution of Genome Size in Gymnosperms
Authors: Ohri Deepak
Published: September 2021

Gymnosperms show a significantly higher mean (1C=18.16, 1Cx=16.80) and a narrow range (16.89-fold) of genome sizes as compared with angiosperms. Among the 12 families the largest ranges of 1C values is shown by Ephedraceae (4.73-fold) and Cupressaceae (4.45-fold) which are partly due to polyploidy as 1Cx values vary 2.41 and 1.37-fold respectively. In rest of the families which have only diploid taxa the range of 1C values is from 1.18-fold (Cycadaeae) to 4.36-fold (Podocarpaceae). The question is how gymnosperms acquired such big genome sizes despite the rarity of recent instances of polyploidy. A general survey of different families and genera shows that gymnosperms have experienced both increase and decrease in their genome size during evolution. Various genomic components which have accounted for these large genomes have been discussed. The major contributors are the transposable elements particularly LTR-retrotransposons comprising of Ty3gypsy, Ty1copia and gymny superfamilies which are most widespread. The genomes of gymnosperms have been acquiring diverse LTR-RTs in their long evolution in the absence of any efficient mechanism of their elimination. The epigenetic machinery which silences these large tracts of repeat sequences into the stretches of heterochromatin and the adaptive value of these silenced repeat sequences need further investigation.

Authors: Erdem Nuran , Karakaya Mustafa
Published: September 2021

Sous vide, French means ‘‘under vacuum’’ the method; comprises pasteurizing foods in a vacuum package in a water bath at fully controllable temperatures (≤100°C). Sous vide is also an enclosure method. The product is consumed immediately after cooking or quickly re-heating between 0-3°C and can be stored for 3-5 weeks until consumption. With Sous vide technology, it is provided to prepare the product at the desired temperature and at the desired time without damaging the textures and quality features, without excessive drying of the outer surface. Meat, fish, chicken and vegetables can be cooked with this method. Meat and meat products prepared with sous vide technology are more delicious, juicy and crunchy and lose their nutrients at minimum level. Sous vide technology offers many advantages such as prolonging storage time, sensory quality and maintaining microbiological quality. Sous vide technology is reliable in many respects since the vegetative forms of bacteria in the food are inactivated by providing anaerobic environment with vacuum packaging and controlled temperature application.

Published: September 2021

It is vital and essential to accurately and timely detect various damages of aircraft engines in civil aviation. Currently, aircraft engines are manually inspected via borescope images by aircraft maintenance technicians. This process is time-consuming and prone to error due to human factors. The aim of this paper is to automate the aircraft engine inspection, and this work presents a deep learning framework with a context encoder neural network structure such that the damaged structures can be accurately segmented from borescope images. Moreover, the proposed network structure is further optimized through an orthogonal-array-based method. With the real borescope images collected from a commercial airline company, the proposed framework is compared with existing deep-learning-based methods from various aspects. The experimental results validate that various damages can be automatically detected and recognized with high accuracy and efficiency by the proposed solution.

Authors: Gupta Vishal , Gupta Savera , Kharghoria Geetali , Pathak Mona , Sharma Vinod Kumar
Published: September 2021

Background:

Although dermatology is mostly an outpatient specialty, some patients with severe skin disease need hospital admission for management. There is a paucity of data regarding the profile of these dermatology in-patient admissions.

Aims:

We studied the profile of patients admitted to the dermatology ward of our tertiary care government hospital in North India.

Methods:

This was a retrospective analysis of discharge sheets of patients admitted in the dermatology ward from January 1, 2014 to December 31, 2017.

Results:

Discharge sheets of 2032 admissions for 1664 patients were analyzed. The most common diagnoses in the admitted patients were immunobullous disorders (576, 28%), connective tissue diseases (409, 20%), infections, including leprosy and sexually transmitted infections (179, 8.8%), psoriasis (153, 7.5%) and reactive arthritis (92, 4.5%). The mean duration of admission was 13.95±11.67 days (range 1-118 days). Two hundred and fifty-six patients (15.38%) were re-admitted, accounting for 368 (18.11%) re-admissions. Patients with immunobullous disorders (OR 1.72, 95% CI 1.29-2.28) and psoriasis (OR 1.62, 95% CI 1.02-2.55) were more likely to be re-admitted. Adult patients, those who were admitted for more than four weeks, those who had comorbidities, and those who developed a complication during the hospital stay also had a greater likelihood of being re-admitted.

Limitations:

The retrospective design of the study, and the non-availability of data regarding transfers to other specialties or intensive care units and deaths were the main limitations of this study.

Conclusion:

This study describes the profile of patients admitted in a dermatology ward of a tertiary care centre center in North India. The patient profile and admission characteristics associated with a higher probability of re-admission were identified.

A total of 260 valid responses were received. Only 28% (73/260) were able to provide at least 50% of professional services as compared to the pre COVID-19 lockdown period. Statistically significant differences related to emotional health (feelings), physical activity, changes in how family sees the lady professional, personal free time availability, and family bonding.

Conclusion:

COVID-19 has led to the following important concerns for professional women - academic productivity; work-life balance; missed opportunities for collaborating; mental health, the need for equity-minded academic leadership, and decision-making. Our study showed that majority were stressed during the COVID-19 lockdown – with the impact being highest among those giving more than 50% of their time to professional medical services outside their homes.
Investigation of the Influence of Cold-Treatment on Properties of Advanced High Strength Automotive Steels
Authors: KARAOĞLU Büşra , KAÇAR Ramazan , ERTEK EMRE Hayriye , NOHUTÇU Samet
Published: September 2021

Due to the moderate formability of low alloy high strength steels, (TRIP) steels called "transformation induced plasticity" have been developed. They are especially used in the production of automobile shock absorbers and the beam supporting parts. The microstructure of these steels consists of the distribution of ferrite, bainite and (5 - 10%) residual austenite phases in the matrix. The strength and formability of steels are generally provided by the residual austenite in the structure. During shaping, the residual austenite turns into martensite and gives high strength to the steel. Considering the literature studies, it is pointed out that there is a lack of information about the effect of cold treatment on TRIP steels. For this reason, in the study, TRIP800 steel has maintained cold treatment for two hours at various temperatures. Thus, the mechanical properties and microstructure changes of the samples were examined in detail.

Published: September 2021

Fatigue of the springs has not been studied widely in the industry. However, damage to the springs during operation can cause major irreversible damages. Since it affects the microstructural properties of the spring material to a high degree, fatigue analysis with various analysis methods cannot give a clear result. In this study, a multiple compression spring fatigue device simulating the real fatigue conditions was designed and produced. Machine design, production and control are also mentioned in detail. The electrical and solenoid operating system is also discussed.
Finite Element Simulation of Dent Resistance For Automotive Rear Bumper
Authors: BAHAR İlker
Published: September 2021

In automotive industry, there is an increasing demand for weight reduction. On the other hand extraordinary style for automotive exteriors are used in order to increase number of sales. As a result, the usage of different shapes for exterior bumpers is getting increased. Because of that, finite element simulation of dent resistance for automotive bumpers has become a very important step in early steps of automotive design. In this paper, static dent resistance for automotive exterior rear bumper is investigated by using nonlinear finite element method. The thickness change for different areas of bumper is considered from CAD data. In addition, nonlinear mechanical properties such as plastic behavior of rear bumper material are used in the finite element simulations. In addition, the results that are obtained from physical test are also presented here to compare with the results of finite element simulations to see percentage of correlation. This study is mainly focused on the correlation between finite element simulations and physical test results. The finite element simulation results show us that the percentage of correlation with the physical test results is reasonable. Consequently, due to high percentage of correlation between nonlinear finite element results and physical test results, the nonlinear finite element results should be taken into account in early steps of automotive design in order to reach minimum cost and get the most robust solution to eliminate quality problems which may occur in the future.

The effectiveness of the supplementary feeding programme for malnourished children aged 6 months to 3 years in Dohuk province, northern Iraq was evaluated. The enrolment criterion was child weight > or = 2 st and ard deviations below st and ard weight-for-age. Children enrolled in the programme in January 2001 were followed over 7 months. Children received high-protein high-energy biscuits in the first month and a monthly child ration for preparing soyabean mix throughout. Their families received food rations in the first 4 months. Improvement was noticed for all children, particularly in the first month. Problems with the rations and within the growth monitoring units resulted in significant drop-out. Use of st and ard growth charts may be a way to overcome this problem. High-protein biscuits should be distributed throughout instead of the mix

Point mutations in the receptor binding domain of low density lipoprotein may increase cholesterol levels in blood. Three mutations of Apo B-100 protein result in defective binding [Arg 3500 —-> [corrected] Gln, Arg 3500 —-> [corrected] Trp and Arg 3531 —-> [corrected] Cys]. We estimated the frequency of Apo B point mutations [codon 3500] C9774T [Arg 3500 —-> [corrected] Trp] and G9775A [Arg 3500 —-> [corrected] Gln] in 179 atherosclerotic, 145 hyperlipidaemic individuals and 272 healthy individuals in the east Mediterranean region of Turkey. Lipid and lipoprotein levels were measured with routine biochemical analyser and Apo B mutation was detected using real-time PCR. Neither mutation was found. In this region, Apo B-100 protein mutations are rare and causes of hyperlipidaemia and atherosclerosis may therefore be unrelated to them

Effects of Ramadan fasting on serum lipids of 20 healthy males in Bangladesh were assessed. Anthropometric parameters and blood lipids were measured 1 day before Ramadan, day 26 of Ramadan and 1 month after Ramadan. Body weight and body mass index decreased significantly during Ramadan compared with before and after Ramadan. Fat intake was significantly higher during Ramadan than after. High-density lipoprotein [HDL] cholesterol increased significantly during Ramadan. Other lipids were not significantly different. Regression analysis of Ramadan HDL cholesterol levels indicated positive association with pulse rate and fat intake and negative association with systolic blood pressure and weight loss. The findings indicate improved HDL cholesterol profiles during Ramadan

Published: September 2021

The abundance of Anopheles arabiensis and its susceptibility to insecticides was studied in New Halfa, eastern Sudan, from March 1999 to June 2000. Of 4854 females anophelines collected, 4847 [99.9%] were An. arabiensis and 7 [0.1%] An. pharoensis. Female An. arabiensis were breeding throughout the year, with 2 peak densities, during the rainy [158.4 females/room/day and 84.7 larvae/10 dips] and irrigated seasons [136.8 females/room/day and 44.8 larvae/10 dips]. The mean biting activity was 28.8 bites/person/ night, found throughout the night, mainly outdoors. Susceptibility of An. arabiensis to insecticides dichloro-diphenyl-trichloroethane [DDT], malathion and fenitrothion was 97.8%, 96.3% and 100% respectively. An. arabiensis is the sole malaria vector in the area and is perennial rather than seasonal
[Typhoid fever in north Lebanon: a 8-year study [1992-1999]using the Widal test]
Authors: Hamze M. , Vincent P.
Published: September 2021

We evaluated the frequency of typhoid fever in north Lebanon over an 8-year period [1992-1999] in patients admitted with fever to the Islami de Bienfaisance Hospital in Tripoli. We analysed 7391 serum samples for Salmonella typhi infection using the Widal and Felix tests. The cut-off value for infection was an agglutinin O titre >/= 1/160 [a value validated in an earlier study in the same region]. Of the 7391 samples, 1131 [15.3%] had an agglutinin O titre >/= 1/160. The 8-year surveillance showed there was a progressive decrease in the frequency of the disease. However with over 100 cases annually, typhoid is endemic in the area and could cause major outbreaks. The monthly analysis shows that we have an increase in summer, whilst a decrease is observed in winter

Published: September 2021

The study was a prospective evaluation of the prevalence of distichiasis and /or dysplastic eyelashes among trachomatous trichiasis cases at the oculoplasty unit of a hospital in Oman over 3 months in 2000. An oculoplasty surgeon examined and photographed cases using a bio-microscope. Out of 80 cases, 58 [72.5%] had abnormal eyelashes in addition to trachomatous trichiasis. The rate of distichiasis and dysplastic lashes were 13.8% [95% CI 6.2%-21.3%] and 33.8% [95% CI 23.5%-44.1%] respectively; 25.0% [95% CI 15.5%-34.5%] had both. Dysplastic and distichiasis eyelashes were significantly more prevalent in trachomatous trichiasis cases aged < 50 years and those with entropion. Presence of distichiasis and /or dysplastic eyelashes in trachomatous trichiasis cases warrants further analytical studies to confirm the observation and establish any causal association
Molecular basis of RhD-positive/D-negative chimerism in two patients
Authors: Eid S. S.
Published: September 2021

This study investigated two patients with Rh chimerism:patient A, a healthy individual, and patient B with myelofibrosis. Flow cytometry studies showed two red blood cell populations of Rh phenotypes R1r and rr at percentages of about 25% and 75% respectively. Normal RhD transcript sequences were found following RT-PCR. Genomic DNA [gDNA] showed normal exon, intron, GATA regions and exon/intron boundary sequences except for a single base change in intron 7 [C –>A] of exon 7 in patient A. The major change found in both patients was the absence of RHD exon 9 DNA in gDNA isolated from peripheral blood. These findings suggest a somatic mutation, probably in a stem cell common to the myeloid lineage of both patients, and indicate that patient A may undergo malignant transformation in the future

Published: September 2021

Anthrax, like tuberculosis, shows a new epidemic spread in industrialized countries, revealing some ambiguous aspects to the disease and providing new challenges to medicine. Shiraz University of Medical Sciences has records of 7130 autopsies performed in the past 40 years, 33 of which are anthrax cases. We reviewed all the pathology slides of these cases and classified the organs involved in a search for unrecognized microscopic findings. The most common cause of death was sepsis, caused by organ involvement and direct cytotoxicity of Bacillus anthracis, in addition to its exotoxin production. Novel findings included hyaline membrane formation in respiratory system cases that is similar to acute [adult] respiratory distress syndrome and evidence of primary gastrointestinal involvement, showing the ability of the organism to pass the gastric barrier

Information on the cost of health services is essential for good planning and management and the efficient use of resources. We calculated the total costs incurred in running primary health services for one year [1995] in the health district of Enfidha [Tunisia]. The yearly operating expenditure for the health district was 1 219 099 Tunisian dinars and the cost per inhabitant was 17.494 dinars [US dollar 1 = Tunisian dinar 0.950 in 1995] ; 65.37% of total costs went on staff and 17.03% on drugs. Looked at another way, 84, 96% went on curative services and 14.04% on preventive services. The cost of a consultation for curative care was 6.847dinars, for perinatal care was 2.764 dinars, for immunization was 3.680 and for school visit was 6.680 dinars. The study helps to identify ways in which cost analysis can be used to explore efficiency and resource adequacy in the district

Published: September 2021

Census and health data were analysed to determine changes in life expectancy at birth during 1987-2000 in the Kuwaiti population and to correlate these with cause-specific annual mortality rates. Life expectancy at birth rose from 73.3 to 75.5 years with a gap between females and males, which increased from 2.2 to 4.5 years. For all causes of death except hypertension and ill-defined conditions, males had higher mortality than females. The leading causes of death in males were ischaemic heart diseases, traffic accidents and cancer, while in females they were cancer, ischaemic heart diseases and hypertension. The problems of an ageing population will need to be considered in planning the health policies of Kuwait

Published: September 2021

The study used capture-recapture methods to determine if information on births, deaths and family planning use obtained from two data sources provides the same or more complete information than that available from a single source. Five different data sources used were:village heads [mukhtars], community health volunteers, primary health care centres, maternal and child care units and local administrative units [health group presidencies] in 10 selected villages in a rural area of Turkey from May to October 1999. Although the numbers of deaths and births were estimated, no estimation of the number of women using any family planning method could be made. The study highlights some data collection problems of the surveillance system in Turkey and recommends that the routine surveillance systems be strengthened
