Authors: Zhou Yunru , Sun Longfeng , Liang Yanting , Mao Guoju , Xu Pei
Published: September 2021

Background: With the global aging problem is becoming increasingly severe, the elderly care has become an important issue that needs attention. Chinese government attaches great importance to the development of medical and health care institutions, and is committed to improving the comprehensive quality of elderly rehabilitation nursing staff in medical and health care institutions.Methods: From June to September 2019, a cross-sectional study among 193 elderly rehabilitation nursing staff was conducted in Liaoning Province, China. Using a self-designed questionnaire, the comprehensive quality of elderly rehabilitation nursing staff in medical and health care institutions was investigated by face to face. The multiple linear regression model was explored to analyze the influencing factors. Results: A total of 193 questionnaires were distributed, and 189 (97.93%) valid questionnaires were recovered. Age was from 19 to 65 years old, with an average age of (38.34 ± 9.76) years old. Bachelor degree or above accounted for 54.00%. 57.10% have engaged in elderly rehabilitation nursing for more than one year. There were 163 nurses with qualification certificates, accounting for 86.20%. The total score of comprehensive quality was 118.52 ± 22.90. The total Cronbach ' s α coefficient of the questionnaire was 0.967, and the content validity index was 0.991. Only 61 (32.30%) elderly rehabilitation nurses received professional training in elderly rehabilitation nursing. The results of multiple linear regression analysis showed that the educational level of elderly rehabilitation nursing staff (P=0.002) and the number of years engaged in elderly rehabilitation nursing (P=0.005) were the main influencing factors of comprehensive quality.Conclusions: The comprehensive quality of elderly rehabilitation nursing staff is at a medium level in Liaoning Province's medical and health care institutions. However, the professional nursing talents was very short, and the education level and years of experience in elderly care were the main influencing factors of the comprehensive quality.

Published: September 2021

The current research studied the performance of novel and cheap catalysts, ultra-stable Y zeolites (USY) and cobalt-modified USY for the efficient production of aromatics from the ginkgo Biloba residue (GBR) using a pyrolysis reactor. Cobalt-modified USY improved the quality of the pyrolysis products e.g. removed unwanted impurities from bio-oil, increased the yield of gases, and overall boosted the GBR conversion. Under the action of USY modified with cobalt, the yield of CO, CH4, and CO2 in the gas production increased significantly, while the yield of H2 was dropped. The selectivity of naphthalene and 1-methylnaphthalene gradually decreased. The composition of aromatic hydrocarbons was reduced, while the content and selectivity ratios of toluene and xylene were increased. This study describes a high-value method using GBR, which could be used as a sustainable resource for the production of hydrocarbons, especially for the preparation of high-quality toluene and phenols.

Published: September 2021

The explosive development of quantum magnonics is explained by its potential of use in quantum computers, processing information and the formation of hybrid quantum systems. The processes of spatial correlation of quantum systems are fundamental and lead to such phenomena as the Josephson effect and superconductivity. In particular, they determine the phenomenon of the magnon superfluidity and magnon Bose condensation which were first discovered in antiferromagnetic superfluid 3He. In this article, we consider the features of magnon Bose condensation in yttrium iron garnet film. We simulate the processes of magnon BEC coherency and magnon tunneling through the gap.
A Framework for Self-Supervised Federated Domain Adaptation
Authors: wang bin , Li Gang , Wu Chao , Zhang WeiShan , Zhou Jiehan , Wei Ye
Published: September 2021

Unsupervised federated domain adaptation uses the knowledge from several distributed unlabelled source domains to complete the learning on the unlabelled target domain. Some of the existing methods have limited effectiveness and involve frequent communication. This paper proposes a framework to solve the distributed multi-source domain adaptation problem, referred as self-supervised federated domain adaptation (SFDA). Specifically, a multi-domain model generalization balance (MDMGB) is proposed to aggregate the models from multiple source domains in each round of communication. A weighted strategy based on centroid similarity is also designed for SFDA. SFDA conducts self-supervised training on the target domain to tackle domain shift. Compared with the classical federated adversarial domain adaptation algorithm, SFDA is not only strong in communication cost and privacy protection but also improves in the accuracy of the model.

Introduction: Campylobacter jejuni is the leading causes of diarrheal disease worldwide among under five years of age. Epidemiological data about C. jejuni and drug susceptibility profile of isolates among children with symptom of gastroenteritis has a paramount importance for evidence based decision. However, such information is not available in the study area. Hence, this study was carried out fill this information gap.Methods: An institution based cross-sectional study was conducted among under-five children (U5C) visiting four primary health centers’ pediatric clinic due to acute gastroenteritis from February to May, 2019. Socio-demographic data were collected in a face to face interview using structured questionnaire. Stool specimen was collected and transported to the Bahir Dar University, Medical Microbiology Laboratory. The specimens were inoculated on Charcoal Cefoperazone Deoxycholate Agar. Identification and antibacterial susceptibility test was performed using standard bacteriological methods. The collected data were entered to EpiData 3.1 and analyzed using SPSS version 23.Results: Among a total of 196 U5C with acute gastroenteritis, 39 (19.9%) were positive for Campylobacter species. The proportion of C. jejuni was 14.8% (29/196). The multivariate logistic regression analyses revealed that care givers (AOR=3.76, 95%CI: 1.29-10.98), guardians hand washing practice before food preparation (AOR=3.63, 95%CI: 1.15-11.46), and contact with domestic animals (AOR=4.23, 95%CI: 1.46-12.28) demonstrated significant association with C. jejuni infection. Among 29 C. jejuni isolates, 24 (82.8%), 24 (82.8%) and 18 (62.1%) were resistant for tetracycline, cefoxitine and erythromycin, respectively. Conclusions: The proportion of C. jejuni infection was high. Children who had contact with animals showed association with C. jejuni infection. Additionally, majority of C. jejuni showed resistance for tetracycline, cefoxitin, ampicillin and erythromycin.

Authors: Asadzadeh Farrokh , pirsa sajad
Published: September 2021

In this study, a composite biosorbent of zein/ethylene diamine tetraacetic acid /chlorophyll/nano-clay (Ze/EDTA/Chl/Clay) was prepared. Thickness, mechanical properties (tensile strength and strength to breaking point), ability to reduce water hardness, water solubility, water absorption, antioxidant activity and moisture content of prepared biosorbent were studied. SEM, FTIR, XRD and TGA techniques were used to investigate the physicochemical properties and structure of the prepared biosorbent. Optimal biosorbent was selected using statistical methods and used to remove chemical contaminants from industrial wastewater in Urmia (Iran). For this purpose, total heavy metals (THM), total hardness, nitrate, nitrite, COD and BOD, TDS and salinity of industrial wastewater before and after biosorbent treatment were investigated. The results confirmed the homogeneous and cohesive structure of different zein adsorbents. FTIR results showed physical and electrostatic interactions between composite components. Nanoclay increased the thermal stability of the biosorbent. Chlorophyll and EDTA increased the biosorbent ability to absorb water and reduce the total hardness of the water. Clay nanoparticles increased the tensile strength of the biosorbent and chlorophyll and EDTA increased the biosorbent ductility. Under optimal wastewater treatment conditions, Ze/EDTA/Chl/Clay biosorbent was recognized as the best adsorbent. The use of ultrasound in wastewater treatment had a good effect. Under optimal conditions, 57.5% of THM and 67% of nitrate were removed from the wastewater. By comparing the ability of chlorophyll-containing biosorbents (Ze/Chl and Ze/EDTA/Chl/Clay) to remove nitrite and nitrate, it was found that these biosorbents have a very high selectivity in nitrate removal compared to nitrite.

The aim of this study was to evaluate the association between the MTHFR 677C > T (rs1801133) genetic variant with susceptibility and severity of peripheral arterial occlusive disease (PAOD) and with serum levels of homocysteine (Hcy). This case-control study enrolled 157 patients with PAOD attended at University Hospital of Londrina, and unrelated 113 healthy individuals from Southern Brazil. The clinical severity of the PAOD patients was assessed by Fontaine classification and anatomoradiological categories by Inter-Society Consensus for the Management of Peripheral Arterial Disease (TASC). The MTHFR 677C > T was genotyped using real-time polymerase chain reaction. The PAOD patients showed higher Hcy than controls but the Hcy did not differ according to Fontaine and TASC categories. Patients carrying the TT genotype (recessive model) or CT + TT (dominant model) presented higher levels of Hcy than those carrying other genotypes. In conclusion, the T allele of MTHFR 677C > T variant was associated with hyperhomocysteinemia in PAOD patients, but not in controls. Moreover, this variant was not associated with the clinical stage and the anatomoradiological categories of PAOD. Our data suggested a possible interaction between MTHFR 677C > T variant and the presence of other genetic, epigenetic and environment factors associated with PAOD on modulation the metabolism of Hcy.

Published: September 2021

Faecal contamination of surface water sources is an important water quality issue worldwide. Although quite a few studies exist on surface water faecal contamination and variability of indicator bacteria, most of the studies have been based on larger river basins and in temperate region. The variability is relatively unknown in local scale and in tropical developing countries. In this study we assess how anthropogenic and environmental factors affect faecal contamination and physicochemical parameters in Rupsha and Bhairab rivers around Khulna city, Bangladesh. Water samples were collected from six locations of the rivers during a wet and dry period in 2018 to measure Escherichia coli (E. coli) concentrations. Water physicochemical parameters—temperature, turbidity, pH, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were also measured. Higher concentrations of E. coli were found in the sampling sites located near the densely populated urban area compared to the downstream site, which receives fewer amounts of discharges from sewer drains. All the E. coli samples violated bathing water quality standards. E. coli concentrations were found to be correlated positively with precipitation and turbidity. A linear regression model was applied, that explains large part of the variation in E. coli concentration (R2 = 0.42). Water quality index assessment was also ranked the water quality as ‘poor’ category; indicate that the water is unsuitable for uses in domestic and recreational purposes and high health risks involved with the water use. The study findings highlight the problem of untreated sewage discharge into the rivers. Implementation of sewage treatment plant with adequate capacity is highly recommended.

Published: September 2021

Background: The SARS-CoV-2 virus has caused patient aversion to health care facilities for fear of contracting the virus. It has been shown that there has been a decreased amount of emergency department visits since the pandemic started1, with an increased presentation of conditions with progressed pathology. At our community hospital, it was anecdotally noted that there was an increase in the number of patients presenting with perforated appendicitis during this time. Our hypothesis is that more patients presented with the progressed finding of perforated appendicitis during rather than prior to the pandemic because of fear of exposure to COVID-19 in the health care setting. Methods: Retrospective chart review of cases of perforated appendicitis at a local community hospital during March 10-December 31, 2019 (cohort A) and March 10-December 31, 2020 (cohort B).Results: A total of three hundred and fifty-two eligible patients received treatment for acute appendicitis at our community hospital. In Cohort A (prior to the pandemic), there were 53 perforations out of 188 patients (53/188) - 28.2%. In cohort B (during the pandemic), there was 61 perforations out of 164 patients (61/164) – 37.2%. Statistically, there was no difference in the rate of perforation between Cohort A and Cohort B, approaching significance (p-value = 0.072). The median age of patients in Cohort A was 38 and in Cohort B it was 43.5 years of age. There was no statistically significant differences between cohorts regarding age (p < 0.23) and sex (p < 0.8). Conclusion: This study found that the number of patients who presented with perforated appendicitis during the pandemic did increase compared to pre-pandemic (37.2% vs 28.2%) but this did not meet statistical significance (p=0.072).

A Hybrid and Robust Delay and Link Stability Aware (DLSA) Routing Protocol for Unmanned Aerial Ad-hoc Networks (UAANETs)
Authors: Hussain Altaf
Published: September 2021

Unmanned Aerial Ad-hoc Network (UAANET) also knows as by the name of Flying Ad-hoc NETwork (FANET) is a new class of Mobile Ad-hoc NETwork (MANET) in which the nodes move in three dimensional (3-D) ways in the air simultaneously. These nodes are known as Unmanned Aerial Vehicles (UAVs) that are operated live remotely or by pre-defined mechanism which involve no human personnel. Due to high mobility of nodes and dynamic topology, the link stability is a research challenge in FANET. From this viewpoint, recent research has focused on link stability with highest threshold value by maximizing Packet Delivery Ratio (PDR) and minimizing End-to-End Delay (E2ED). In this research, a hybrid scheme named Delay and Link Stability Aware (DLSA) routing scheme has been proposed with the contrast of Distributed Priority Tree-based Routing (DPTR) and Link Stability Estimation-based Routing (LEPR) FANET’s existing routing schemes. Unlike existing schemes, the proposed scheme possesses the features in collaborative data forwarding and link stability by merging the positive features of DPTR and LEPR. The link stability via maximum threshold value has been introduced to acquire and select the most feasible route from source to destination. The simulation was carried out using Matrix Laboratory (MATLAB) tool for the concerned research. Simulation results have showed improved performance of the proposed protocol in contrast to the selected existing ones in terms of E2ED, PDR, Network Lifetime and Transmission Loss. Average E2ED in (milliseconds) of DLSA measured 0.457, while DPTR was 1.492 and LEPR was 1.006. Similarly, Average PDR (in %age) of DLSA measured 3.106, while DPTR was 2.303 and LEPR was 0.682. Average Network Lifetime in (seconds) for DLSA measured 62.141, while DPTR was 23.036 and LEPR was 27.298. Average Transmission Loss in (dBm) for DLSA measured 0.975, while DPTR was 1.053 and LEPR was 1.227.

Published: September 2021

PURPOSE:Bimedial rectus recession is one of the surgical treatment options for infantile esotropia. It is mainly performed with the Hang-Back technique, which has undesirable side effects. In this study, this technique has been modified, and its results are discussed.METHODS:The files of 120 patients followed with the diagnosis of infantile esotropia and treated bimedial rectus muscle recession using the modified Hang-Back technique were reviewed retrospectively. Cases were evaluated by the time of surgery, coexistence with inferior oblique muscle weakening surgery, and presence of refractive error. The factors investigated on the results of surgical treatment were determined as age, gender, amount of hyperopic refractive error, application age, amount of horizontal deviation, amount of recession, stereopsis, fusion, age of surgery.RESULTS:When the cases were divided into subgroups which were the time of surgery, the operation performed with inferior oblique weakening surgery and presence of refractive error; the difference between preoperative and postoperative 1st month, 6th month, and 1st-year angle of deviation was statistically significant in all three groups (p < 0.001).CONCLUSION:This novel technique aims to prevent unwanted movement of the muscle in the horizontal and vertical axis and a gap in the middle of the recessed muscle, seen in the classical Hang-Back technique. The difference between the preoperative and postoperative angle of deviation was statistically significant. Also, over and under-correction and the development of alphabetic pattern deviation were less common in our modified technique.

Published: September 2021

Coriolis Vibratory Gyroscope (CVG) is an inertial rotation rate measurement sensor for inertial navigation applications. The rotation sensitive element is a hemispherical vibrating resonator, made of fused silica. It is forced to vibrate at a particular resonant mode with electrostatic forcing. As the resonator is a glass material its vibration amplitude is limited to the submicron level. An ultra-high vacuum environment is necessary for the resonator to sustain the vibration amplitude. Securing the required vacuum level is critical in sensor development. A detailed analysis has been carried out on the damping forces present at various ambiance conditions, the need for threshold vacuum level, threshold forcing voltage for the resonator, and different ways of degradation of the vacuum level in the sensor capsule. This paper presents an experimental study on the damping forces that appear on the resonator by measuring the Q factor at various vacuum levels, vacuum leak rate through weld joints, securing the vacuum environment, and remedial action to arrest vacuum in the sensor volume. Dedicated test setups have been established to carry out the experimental research work.

Authors: Baniak Józef
Published: September 2021

W artykule tym ukazuję poglądy i postawy uczniów szkół średnich i studentów uczelni wyższych w Polsce wobec moralności seksualnej postrzeganej w świetle zasad etyki katolickiej. Postawy te respondenci przejawiali w drugiej połowie XX wieku i w dwóch kolejnych dekadach XXI wieku. Podstawę analizy postaw licealistów i studentów stanowią wyniki wielu badań socjologicznych, zrealizowanych w obu częściach przyjętego okresu. Badania te ukazują, w jakim stopniu i zakresie polska młodzież zmieniała w tym czasie własne nastawienie – poglądy i postawy – dotyczące katolickiej moralności seksualnej, katolickich zasad etycznych regulujących seksualność ludzi oraz wobec stanowiska Kościoła katolickiego w tej kwestii. Pytanie to stanowi też problem główny przedstawianego artykułu. Z kolei omówienie postaw i zachowań młodzieży dotyczących katolickiej moralności seksualnej stanowi jego przedmiot. Dokładna prezentacja badań socjologicznych i analiza ich wyników stanowi metodę zastosowaną w tym opracowaniu. Na treść opracowania składają się następujące zagadnienia dotyczące nastawienia młodzieży polskiej do katolickiej moralności seksualnej: 1) przedmałżeńska czystość seksualna i jej wartość; 2) współżycie seksualne po ślubie cywilnym, a przed ślubem kościelnym; 3) rola i znaczenie współżycia seksualnego w małżeństwie; 4) antykoncepcja i naturalna regulacja poczęć; 5) aborcja – jej sytuacje i okoliczności oraz konsekwencje; 6) pozaustrojowe zapłodnienie metodą in vitro a leczenie niepłodności w małżeństwie i w innych związkach.

Authors: Bouchet Dominique
Published: September 2021

W artykule zwrócono uwagę na socjologiczny kontekst stworzenia jednej z najbardziej znanych postaci rysunkowych – Gala Asterixa. Przedstawiono pochodzenie jego autorów oraz ich prace, będące wyrazem ich drogi życiowej, podejmowanych decyzji oraz światopoglądu. Ważne znaczenie ma tutaj zagadnienie migracji oraz nawiązywania do własnych losów. Losy twórcy Asterixa są zatem pewnego rodzaju przykładem na bogactwo i złożoność kultur, które finalnie mogą przynieść bardzo dobre rezultaty w tworzeniu dzieł uniwersalnych, zrozumiałych dla każdego i cieszących się wielką popularnością. Gal Asterix jest wykreowaną postacią, która odniosła sukces w kulturze masowej, zatem niezwykle ważne są próby wyjaśnienia jej fenomenu, właśnie poprzez analizę życia i relacji społecznych jego twórcy.
A review of tele-dermatology during the COVID-19 pandemic and its future. (Preprint)
Authors: Wu Xiaotian
Published: September 2021

BACKGROUND

As the COVID-19 pandemic rages on worldwide, social distancing and minimising face-to-face interactions remain key to reducing the spread of disease. As a result of this change, the field of tele-dermatology has matured rapidly and has become widely adopted.

OBJECTIVE

The objectives of this paper are to review the literature on the use of tele-dermatology during the COVID-19 pandemic - to identify how tele-dermatology services were implemented, the benefits of tele-dermatology, its challenges and limitations, and the implications for tele-dermatology in the future.

METHODS

A literature search for articles on the PubMed database was conducted using the keywords “tele-dermatology” and “COVID”. Results were filtered for articles written in English and published in the years 2020 and 2021. We included articles that meet the following criteria: studies that describe the experiences of an institution that has implemented tele-dermatology during the COVID-19 pandemic or qualitative studies surveying the perceptions of patients and/or doctors after using tele-dermatology as a platform. We excluded articles that merely discussed tele-dermatology without describing any first-hand experience. To prevent duplication of findings, we also excluded system reviews. Relevant articles were identified by their title and abstracts. Full text, where available, were retrieved for the identified articles.

RESULTS

The results were retrieved on 26th May 2021. A total of 112 results were identified. 33 articles met the inclusion criteria, of which 30 articles had full text available for retrieval. The following themes were identified from the articles and discussed: implementation of tele-dermatology, the benefits of tele-dermatology during a global pandemic, the limitations of tele-dermatology, and the possible role of tele-dermatology in the future.

CONCLUSIONS

The COVID-19 pandemic has certainly hastened the adoption of tele-dermatology worldwide. As we adapt to the increasing prevalence of this relatively new platform and overcome its various barriers and limitations, there is no doubt that tele-dermatology will play a significant role in the care of patients suffering from skin diseases in the post COVID-19 era.

La societalización de la pandemia en México
Authors: Arteaga Botello Nelson
Published: September 2021

Se analiza cómo se societalizó el primer esfuerzo del gobierno de México por controlar el brote de Covid-19. La societalización ocurrió cuando el presidente fue acusado de ser una amenaza la salud pública del país al asegurar que su superioridad moral lo hacía inmune al virus e impedía que fuera fuente de contagio. La polarización política del país evitó, como en otras ocasiones, que la societalización se tradujera en regulaciones o sanciones al presidente. Los argumentos contra el presidente se transformaron en un sedimento simbólico traído a cuenta por la esfera civil en otros esfuerzos por societalizar la pandemia.

Published: September 2021

El 28 de septiembre de 1821 se declaró la Independencia del Imperio Mexicano. Poco se ha reparado en el hecho de que el nacimiento de México se llevó dentro de la vigencia de un orden constitucional moderno, regido parcial y temporalmente por la Constitución española de 1812 y por los principios establecidos en el Plan de Iguala y los Tratados de Córdoba, considerados como las primeras leyes fundamentales, hasta que el congreso mexicano expidiera la primera constitución propiamente mexicana. Este hecho y este acto jurídico fueron únicos en la historia política latinoamericana y reflejaron una vocación constitucionalista.

Este trabajo analiza algunas pictografías de códices originales exhibidas en el Museo Nacional de Antropología (Ciudad de México) y un problema en particular: la relación que guardan los conceptos altépetl –ciudad, población establecida– y tlatocáyotl –forma de gobierno del tlatoani–. Significativamente, ambos conceptos aparecen en los códices de manera extendida, ya sea a través de un glifo toponímico o una voluta de la palabra. El propósito es determinar su presencia y su posible relación con los inicios de los asentamientos urbanos y las formas de gobierno que adoptaron los grupos nahuas del altiplano central, antes y después de la conquista.
Prague Spring’s Demise: The Involuntary Emigration of the Journalist Vladimír Tosek
Authors: Spenser Daniela
Published: September 2021

The television journalist Vladimír Tosek broadcasted the occupation until the transmission was discovered, and he was forced to cross the border to Austria. He did not want to emigrate, but the radical political change, which culminated in April 1969, forced him to exile. The Czechoslovak authorities made him pay a heavy price for daring to defy the occupiers in 1968 by making public his previous collaboration with the state secret police. In doing so, the government sought to discredit Tosek and his colleagues in the mass media who identified with and defended vigorously the reform process.

Färger och kulörer på väggar, tak, möbler och inredningstextilier har studerats utifrån ett tvärvetenskapligt, hantverks- och konserveringsvetenskapligt perspektiv. Forskargruppen har specialistkompetens inom kemi, fysik, konservering, etnologi och konstvetenskap. Teoretiskt och praktiskt utgår analyserna i studien från själva görandet, dess kulturella och sociala kontext, materiella förutsättningar och resultat samt de val som är involverade i varje enskild procedur i hantverksprocessen. I analysen samverkar flera tidskikt. Undersökningen utgår från 1700- och 1800-talens fasta och lösa interiörer i hälsingegårdar, bland annat de sju världsarvsgårdarna, och museisamlingar. Det unika med forskningsprojektet har varit att kombinera humanistisk teoribildning med naturvetenskaplig analysmetodik. Med ett konstteknologiskt källforskningsperspektiv har en holistisk bild av detta materiella och immateriella kulturarv erhållits.

Published: September 2021

För att förstå hur vissa gårdar i Hälsingland kom att utnämnas till världsarv är det viktigt att reda ut hur begreppet ”hälsingegårdar” skapades. Frågor som diskuteras i artikeln är: vilken materialitet har hälsingegården förknippats med? Vad har bevarats och av vilka skäl? Hur såg musealiserings- och kulturarvsprocessen ut från identifiering och dokumentation, via forskning och medial förmedling, fram till nomineringen av sju hälsingegårdar som världsarv?

Artikelns fokus ligger på material och tekniker som användes vid tillverkning av underlaget i Hälsinglands inredningar. Det tidiga väggmåleriet under 1700-talet var framför allt utfört på trä eller textil, medan 1800-talet domineras av papper som underlag. Trä av olika slag utgör underlaget i målade möbler, textilfibrer i olika tekniker utgör underlaget i den textila inredningen. I artikeln beskrivs de varierande underlagsmaterialen i detalj utifrån egenskaper, tekniker och hantverkares kunskaper. Sista delen fokuserar på papper och papperstillverkning, där exempel ges på hur pappersark kunde framställas hantverksmässigt på 1700- och 1800-talen.

Abstract: Loss of data implies loss of valuable information. An appropriate gathering of data and finding hidden patterns out of it is key for any business organization to thrive fiscally. With exponential rise in the internet users from the early 2000’s, traditional databases fell short to collect the enormous amount of unstructured data/ semi-structured data, which contained extremely insightful information. Today, data accumulated is not only enormous, but also collected with high speed, having variety, which necessitated special database/software for data gathering and making key decisions based on that. These gigantic amounts of data generated can advocate companies to examine the market trends, market demands, and customer expectation, which endorses them to make relevant foremost decisions. This study discusses the stymie in conventional databases to process the immense data and entailment of advanced databases/software. Furthermore, a case study is presented later to understand the role of big data analytics in business and technical firms. Keywords: Big Data, structured data, unstructured data, NoSQL, Hadoop.
The application efficiency of intumescent coatings for power cables of safety systems of nuclear power plants under fire conditions
Authors: Lebedchenko O. S. , Puzach S. V. , Zykov V. I.
Published: September 2021

Introduction. The reliable operation of safety systems, that allows for the failure of no more than one safety system component, entails the safe shutdown and cool-down of an NPP reactor in the event of fire. However, the co-authors have not assessed the loss of performance by an insulating material, treated by intumescent compositions and used in the power cables of the above safety systems exposed to the simultaneous effect of various modes of fire and current loads.Goals and objectives. The purpose of the article is the theoretical assessment of the application efficiency of intumescent fire-retardant coatings in power cables used in the safety systems of nuclear power plants having water-cooled and water-moderated reactors under fire conditions. To achieve this goal, the temperature of the outer surface of the insulation and the intumescent fire-retardant coating was analyzed depending on the mode of fire. Theoretical foundations. A non-stationary one-dimensional heat transfer equation is solved to identify the temperature distribution inside the multilayered insulation and the fire-protection layer of a conductive core.Results and their discussion. The co-authors have identified dependences between the temperature of the outer surface of the insulation and the fire retarding composition of the three-core cable VVGng (A)-LS 3x2.5-0.66, on the one hand, and the temperature of the indoor gas environment for three standard modes of fire and one real fire mode. It is found that before the initiation of the process of destruction of the insulation material, the intumescence of the fire-retardant coating occurs only in case of a hydrocarbon fire. Under real fire conditions, the maximal insulation melting time before the initiation of intumescence of the fire-retardant coating at the minimal temperature of intumescence is 4.75 minutes, while the maximal time period from the initiation of destruction of the insulation material to the moment of the insulation melting is 6.0 minutes.Conclusions. An experimental or theoretical substantiation of parameters of intumescent fire retardants, performed using standard modes of fire, has proven the potential loss of operational properties by insulating materials of power cables, used in the safety systems of nuclear power plants, in case of a real fire. Therefore, it is necessary to establish a scientific rationale for the efficient use of fire retardants in the above cables with regard for the conditions of a real fire.

Much valuable information about the development of Parkinson’s disease (PD) has been obtained from studies on the laboratory animals. Objectives. To compare the development of neurotoxic and neuroinflammatory parkinsonism syndrome in laboratory animals. Material and methods. The number of rats in the group of neuroinflammatory model of parkinsonism syndrome (lipopolysaccharide) was 6, and in the group of neurotoxic model (rotenone) - 20. The control group consisted of 5 animals. The study was approved by the independent Ethics Committee. The development dynamics of parkinsonism syndrome of neurotoxic and neuroinflammatory genesis was assessed in the study of the motor activity of animals, as well as in the laboratory study of biomarkers of dopamine metabolism (dopamine and homovanillic acid) in blood serum and cerebrospinal fluid obtained in 7 and 21 days after the first administration of rotenone or lipopolysaccharide, and also after a single intravenous injection of allogeneic (rat) multipotent mesenchymal stromal cells (MMSC) carried out after 9 injections of rotenone. Results. A decrease in the levels of dopamine and homovanillic acid has been shown in laboratory animals on the development of Parkinson’s syndrome. In rats with a neuroinflammatory model of parkinsonism syndrome, a pre-motor stage of motor disorders development has been laboratorially confirmed. During the first weeks after the introduction of MMSC, regression of the motor symptoms of neurotoxic parkinsonism syndrome and a parallel increase in dopamine and homovanillic acid are determined. Conclusions. The effectiveness of MMSC in the early post-transplantation period is associated with the paracrine effect. It is proposed to call activated microglia, a potential therapeutic target in PD, neuroinflammatory penumbra.

The purpose of this article was to analyze the pharmaceutical market of the tissue sealing agents group of the Republic of Belarus from 2010 to 2018 based on the data presented in the Medmarket database and the State Register of Medicines of the Republic of Belarus of UE «Center of Expertise and Testing in Healthcare». The group of tissue sealing agents (B02F) was found to be characterized by high growth rates and a relatively large market share. During the studied period, it was represented on the Belarusian pharmaceutical market by only one drug - Tachocomb (manufactured by Takeda Pharmaceutical Company Limited, Japan). When analyzing its dynamics in the period from 2010 to 2018 it was found that, in general, the change in the volume of the market for tissue sealing agents correlates with the change in the volume of the total market for hemostatic drugs over the years. During 2010-2018 there is an increase in the volume of sales for this local sealant, both in monetary (by 1.51) and in natural (by 2.01) expressions with a gradual fall of the price. It has been concluded that the development of the tissue sealing agents by domestic manufacturers is urgent and expedient.

Un total de 46 ovejas nulíparas Katahdin se asignaron bajo un diseño de bloques completamente al azar a dos tratamientos dietarios (n= 23) alrededor del empadre para evaluar el efecto de adicionar ácidos grasos poliinsaturados (AGP) sobre el comportamiento reproductivo y el crecimiento pre-destete de las crías. Los tratamientos consistieron en dos concentrados isoenergéticos e isoproteícos formulados sin (testigo) y con AGP omega 6, los cuales se ofrecieron durante 42 d (7 d antes y 35 d de exposición al semental). La adición dietaria de AGP disminuyó (P<0.05) el intervalo a estro, sin afectar (P>0.05) las demás variables reproductivas. En crías, el peso al nacimiento no varió (P>0.05) con la adición de AGP; sin embargo, la inclusión dietaria de AGP aumentó (P<0.05) la tasa de crecimiento pre-destete y el peso al destete en corderos, pero no en corderas. La inclusión de AGP en la dieta también mejoró (P<0.05) el crecimiento pre-destete en crías de parto gemelar pero no en crías de parto simple. En conclusión, la inclusión de AGP omega 6 en la dieta de ovejas nulíparas Katahdin durante el empadre, redujo el tiempo de aparición del estro sin afectar otras variables reproductivas; asimismo, mejoró el crecimiento pre-destete de sus crías machos y aquellas nacidas en parto gemelar.
