The Exact Linear Turán Number of the Sail
Authors: Ergemlidze Beka , Győri Ervin , Methuku Abhishek
Published: December 2021

A hypergraph is linear if any two of its edges intersect in at most one vertex. The sail (or $3$-fan) $F^3$ is the $3$-uniform linear hypergraph consisting of $3$ edges $f_1, f_2, f_3$ pairwise intersecting in the same vertex $v$ and an additional edge $g$ intersecting each $f_i$ in a vertex different from $v$. The linear Turán number $\mathrm{ex}_{\mathrm{lin}}(n, F^3)$ is the maximum number of edges in a $3$-uniform linear hypergraph on $n$ vertices that does not contain a copy of $F^3$.

Füredi and Gyárfás proved that if $n = 3k$, then $\mathrm{ex}_{\mathrm{lin}}(n, F^3) = k^2$ and the only extremal hypergraphs in this case are transversal designs. They also showed that if $n = 3k+2$, then $\mathrm{ex}_{\mathrm{lin}}(n, F^3) = k^2+k$, and the only extremal hypergraphs are truncated designs (which are obtained from a transversal design on $3k+3$ vertices with $3$ groups by removing one vertex and all the hyperedges containing it) along with three other small hypergraphs. However, the case when $n =3k+1$ was left open.

In this paper, we solve this remaining case by proving that $\mathrm{ex}_{\mathrm{lin}}(n, F^3) = k^2+1$ if $n = 3k+1$, answering a question of Füredi and Gyárfás. We also characterize all the extremal hypergraphs. The difficulty of this case is due to the fact that these extremal examples are rather non-standard. In particular, they are not derived from transversal designs like in the other cases.

Thus, the problems and obstacles to tourism development in Khmelnytskyi region are considered and a number of areas are identified to address the relevant shortcomings, as well as recommendations for improving existing places for tourism and opening new ones for greater promotion among the population. The tourist potential of the region is characterized. The information on the number of tourists served by tour operators and travel agents for a certain period is analyzed. They noted that due to the tourist tax, the community budget is better filled, so this industry should be actively developed. The program of tourism and resorts development, the way it is applied into practice of Khmelnytskyi region is studied. It is pointed out that among the tourist centers of Khmelnytskyi region a special place is devoted to the city of Kamianets-Podilskyi, its local authorities pursue a very active tourism policy, setting goals to be achieved in a short period of time. It is noted that the main tasks of tourism development in the Khmelnytskyi region are the formation of a tourist and recreational complex that would meet the needs of the population in spa treatment, recreation and tourism. Recommendations are given for the application of a number of marketing measures that would help expand knowledge about Khmelnytskyi region far beyond its borders.

Theoretical and Applied Aspects of Public Governance in the Field of Tourism in the Conditions of Adaptation to EU Standards
Authors: HRABAR Nataliia , LEONENKO Nelli
Published: December 2021

The article is devoted to the study of public administration in the field of tourism in terms of adaptation to the standards of the European Union. Emphasis placed on the fact that the state of domestic policy in the field of tourism does not meet modern world standards of industry management at the state level. In connection with the transition from a planned to a market model of state development in the last two decades, there have been clear problems that prevent the full use of the tourist and recreational potential of Ukraine. On the one hand, the underdevelopment of domestic tourism correlates with the general problems of political, social and economic nature inherent in developing countries at a certain stage of their development. On the other hand — the lack of the necessary methodological framework and lack of methodological developments for state regulation of tourism correlates with the impossibility of practical application of tourism laws, tourism development programs and the formation of tourism regulation structures at the national level, which directly and indirectly affect the adaptation of Ukrainian legislation and state-management activities in accordance with the standards of the European Union. Based on the results of doctrinal and comprehensive research, it concluded that in the context of promoting the gradual convergence of domestic and European public administration environment, strengthening economic and trade relations that will lead to Ukraine’s gradual integration into the EU internal market, expanding cooperation based on the rule of law and respect for the rule of law. Human rights and fundamental freedoms, the sphere of tourism occupies one of the key aspects not only at the national level but also at the international level. At the same time, in the context of adaptation of domestic legislation and public administration to EU standards, it is advisable to develop a methodology and action plan aimed at implementing the holistic guidelines and principles enshrined at the European level.

The Epistemological Aspects of Investigative Hypotheses
Authors: David Petretei
Published: December 2021

This paper is about the philosophical and epistemological aspects of investigative hypotheses.Criminal investigation is a kind of cognition, so it is important to know the basic philosophic conceptof knowledge and truth. Different schools and traditions of philosophy have given different answers tothese.One of the basic elements of investigative thinking is, in addition to being reconstructive andretrospective, thinking in hypotheses. Logical, semantic, syntactic, epistemological, and ontologicalprinciples must be taken into account when formulating hypotheses. Choosing between the hypothesesshould be based on preference and indifference criteria. These criteria of preference and indifferencewill also be logical and epistemological.Testing, validating, and rejecting hypotheses is an essential element of investigative work. Theplausibility, credibility, and accuracy of competing hypotheses are constantly changing dependingon the investigative data obtained. It is a basic principle that all hypotheses should be tested and, ifpossible, the testing should be performed in parallel.

Published: December 2021

The study was designed to explore the distribution and association of the biofilm genotype pattern(algD −/pslD −/pelF –) with multidrug-resistant in clinical local Pseudomonas aeruginosa isolates. Atotal of one hundred isolates of Pseudomonas aeruginosa were included in this study, which has beencollected from different specimens, from July to September 2020. The isolates included were 34 fromburns, 19 from wounds, 23 from ear infections, 22 from urinary tract infections (UTI), and 2 from cysticfibrosis (CF). Identification of the isolates was carried out using microscopical, cultural characterizationon MacConkey agar, Cetrimide agar, then Pseudomonas agar. Biochemical tests were performed, andfurther identification was carried out by the VITEK_2_compact system. Genotypic identification hasbeen completed by16SrRNA. To assess the frequency of multidrug-resistant of Pseudomonas aeruginosa(MDR), the antibiotic susceptibility test was done. It was carried out by using different groups ofantibiotics (10 antibiotics) using the Kirby–Bauer disk diffusion method. The results showed that theresistance were Ceftazidime(62%),Gentamicin(26%,(Piperacillin-tazobactam(25%), Ticarcillin(24%),Meropenem(20%), Cefepime (18%),Amikacin(17%) Levofloxacin(16%), Colistin(15%) Imipenem(10%).Biofilm production was assessed using a microplate examination method. The results showed that 93%of isolates were positive for biofilm production, while (7%) were non-biofilm producers. There weredifferences in the rates of biofilm-production distributed into 21 (21%) were strong biofilm producer(OD was more than 2.156), 25 (25%) intermediate biofilm producer, and 47 (47%) were weak biofilmproducer (OD was less than 1.078), and the non -biofilm producer was 7(7%).Three virulence factors genes ( algD, pslD, and pelf ) were chosen, which responsible for the phenotypicpattern of biofilm formation and identified as genotypic algD −/pslD −/pelF – pattern. The differencesin genotypic pattern prevalence among the MDR-positive isolates of different origins were statisticallysignificant. Chi-square analysis showed a highly significant association between strong biofilm capacityand genotype pattern (p<0.0001), also the analysis showed a highly significant association betweenmoderate biofilm capacity and genotype pattern (p<0.002). Chi-square analysis showed a highlysignificant association between weak biofilm capacity and genotype pattern ( p<0.001).In the current study the percentage of resistance among P. aeruginosa local isolates for multiple antibiotics(MDR) was relatively low, maybe due to the combination strategies based on appropriate anti-pseudoantibioticagents that may be used to improve treatment from the related infections, according to theseresults, P. aeruginosa local isolates that produced biofilm were mostly (70%) indicated as non-MDR.

Published: December 2021

This article discusses the distribution of pandemic in the world and pandemic curve in Jordan and how the science of probability and statistics predict when active cases tend to zero by determining the shape of epidemic curve and relating it to a special probability distribution that has specific measures and properties. At the beginning of the outbreak of any virus in a society, reliable data describing it and its spread will be rare, hence researchers set up statistical models that have the ability to predict the spreads’ shape, where the prospected people hosting such viruses will go to and the likelihood of transmitting it to places they travel. Those models use known statistical measures that estimate the probability of disease transmission from infected people to others. In addition, the factors related to roads and people’s movement, taking into consideration, public health interventions, such as wearing masks, closing places of people’s aggregations like schools, universities mosques and churches and quarantine make difference in numbers of infected people. The fundamental differences between the “Spanish flu” that attacked the world a hundred years ago and “Coronavirus” the world facing since the beginning of the current year 2020 is the amount of huge data concluded from scientific studies and reports related to virology and epidemiology.

Published: December 2021

The current study aimed to extract and purify the phenolic compound Resveratrol from dried blackgrape residues, Vitis vinifera, which were purchased from the local market in Iraq. Resveratrol wasextracted from sun-dried grape residues with 2.5 liters of 80% ethanol. Then the compound resveratrolwas concentrated using a rotary evaporator and dried in very high freezing conditions after beingfiltered with animal charcoal. A partially purified material was obtained after a column chromatographyprocess, where 9 grams were obtained for every 600 grams of grape residues as a result of these steps.Chemical tests were conducted to detect resveratrol, and they included: general tests for polyphenols,detection of unsaturated cyclic compounds, high-efficiency liquid chromatography (HPLC) method.The results showed the appearance of two peaks at a wavelength of 280 nm for the compound resveratrolextracted from grape residues, where the time of its appearance was at 4.267 /min compared with thestandard compound resveratrol which was at 4.356 /min. The concentration of the resveratrol extractwas 107.6 ppm. The total antioxidant activity of resveratrol extracted from grape residues and thestandard compound resveratrol was estimated. The total antioxidant activity of resveratrol extractedfrom grape residues was 71.14%, while it was 62.21% for the standard compound resveratrol. Theresults showed that the resveratrol compound extracted from grape residues was purified in the darkto prevent the conversion of resveratrol from trans to cis. The study also shed light on the quantities ofresveratrol contained in grape residues, and this depends on the extraction steps as well as the purposeof its applications.

Background: Chlorpromazine (CPZ) is a phenothiazine tranquilizer used in humans and animals. Rapid determinationof the drug in pharmaceutical preparations is often needed. The aim of the study was to further examine and ascertainasimple spectrophotometric method in comparison with a high performance liquid chromatographic (HPLC) methodfor the determination of CPZ concentrations in injectable pharmaceutical formulations used in man and animals.Methods: Concentrations of CPZ in injectable pharmaceutical formulations for human and veterinary uses weredetermined by a modified spectrophotometric method and by an HPLC method with appropriate standard calibrationcurves. The spectrophotometric method of CPZ determinationwas conducted by diluting 0.1 ml of the veterinary(5%) or 0.3 ml of human (0.5%) formulations to 200 ml of 0.1N sulfuric acid. Four ml of the diluted CPZ samples orthe standard solutions were mixed with 2 ml of 50% sulfuric acid. Then an aliquot of 0.2 ml of 2% ferric nitrate wasadded to the mixture. After 15 minutes, the absorbance was measured at 530 nm against water and vehicle blanksusing a spectrophotometer. The HPLC method applied in the present study consisted of reversed phase gradientchromatography with a C18 column and the eluent was (A) 50 mmol NaH2PO4, pH 2.5 and (B) acetonitrile - 50mmol NaH2PO4, pH 2.5 (60:40 v/v), flow rate at 1 ml/min, with a gradient of 15-55% B in 10 min, to 100% B in20 min, and 280-nm UV detection. From the calibration curves of CPZ standards, the following were calculated:Limit of detection limit (LOD) = 3.3 x SD/slope; Limit of quantitation (LOQ) = 10 x SD/slope, where SD is thestandard deviation of response of CPZ concentrations of the calibration curves.Linear regression analysis and relatedcoefficients of correlations were applied on the calibration curves. Results: The calibration curves of CPZ againstwater or vehicle blanks as determined by the spectrophotometric method or by the HPLC method were linear withstrong correlations (r = and / or >0.99). Based on the calibration curves, limit of detection and limit of quantitation thespectrophotometric method were comparable to those of the HPLC one. The contents CPZ in human and veterinaryinjectable formulations as determined by the spectrophotometricmethod were in accordance (100.6% and 102%,respectively)to the concentrations claimed on the labels of the formulations.Conclusion: The present results introduce a simple spectrophotometric method that could be used for routinemeasurement of CPZ concentrations in pharmaceutical formulations, with the added benefits of linearity, precisionand cost effectiveness.

Published: December 2021

The aim of the study is to develop and determine the maximum acceptable reliability factor of state aviation helicopters based on statistics on malfunctions that occur during the operation of the aviation materiel, taking into account the recommendations of ICAO.

The paper defines the general criteria for calculating the limit values of reliability (operational reliability and flight safety). For their implementation it is necessary:

to carry out constant monitoring of flight safety and the general reasons which cause emergence of malfunctions of helicopters, their systems and subsystems;

to use the proposed combined model on the principle of "traffic light" to determine the level of flight safety indicators at their standard deviation when justifying decisions on the forecast for future periods of operation and establishing certain values of forecast indicators of the "upper control limit" of operational

Based on the adopted conceptual approach to determining the dynamics of change in failure rates, quantitative criteria are developed. Proposals to determine the indicators of the technical condition during the military operation of the aircraft will maintain high combat readiness of state aviation at a given level, predict the need for maintenance and repair and predict the timing and direction of modernization of aircraft.
INCREASE IN ACCURACY OF MEASURING AIR OBJECTS ANGULAR COORDINATES DURING MULTICHANNEL RECEPTION OF RADIO-LOCATION SIGNAL

Radars with a phased array antenna (PAA) which performs multi-channel radar signal reception are effective means of obtaining radar information about air objects in difficult conditions of air and jamming environment. Radar surveillance for radars with PAA is accompanied by a significant negative effect of tropospheric inhomogeneity, which causes a decrease in the accuracy of measurements of azimuth angles and air object‟s position due to fluctuations of the phase front of the received wave reflected from an air object. According to the results of research, the hypothesis of a normal distribution law of these fluctuations is accepted. The paper presents the results of estimating the root mean square errors of measuring the angular coordinates of the air object, which occur if the fluctuations of the phase front of the received signal‟s wave are not taken into account and analyzes the possibility of reducing such errors when the fluctuations are considered.

The possibility of optimizing the angular measurements of air objects in digital radars with PAA is shown, which consists in taking into account the fluctuations of the phase front of the received signal in the algorithm of discrete (fast) Fourier transform, which is widely used to provide spatial measurements in modern digital radar stations. The results of previous studies were generalized, which makes it possible to evaluate the possibility of increasing the accuracy of angular measurements of air objects during multichannel reception of a radar signal in difficult conditions of radar operation.
Investigation of the wear of rolls in asymmetric rolling

Published: December 2021

In the present work, both symmetric and asymmetric rolling processes were investigated by means of numerical approaches. From the algorithm presented, the values of rolling pressure and sliding velocity in the roll gap were determined. These variables allow the estimation of tribological parameters of a given material. To determine the wear of the rolls and rolled materials the Archard's law has been employed. Results of numerical simulations show that the quantitative characteristics of the wear reveal a slight change for slower roll. Whereas the wear value for the faster roll increases with an increase of roll velocity ratio. It was found that for a given roll velocity ratio, rise of friction coefficient causes insignificant change in the wear value for the slower roll, while this value tends to decrease rapidly for the faster roll.

Published: December 2021

The evolution in the field of recrystallization related studies in FCC metals is summarized in this paper. The process of recrystallization which is initiated by stored energy is provided by dislocations. However, dislocations are introduced during the process of deformation, hence both aspects are covered, as well as the kinetics of recrystallization is well elaborated. The key features of recrystallization: role of misorientations; deformation and recrystallization textures; are described and most importantly recent issues on recrystallization of FCC metals are documented in this paper. The final remarks contain the future aspects of studies in the field of recrystallization of materials with FCC crystal structure.
