Authors: Biały Witold , Ivanova Tatiana Nikolajevna , Žarnovský Jozef , Ružbarský Juraj
Published: August 2020

A direct influence on the physical and mechanical state of the surface layer of wedge-shaped plates made of 8KHF steel is exerted by heat generation processes developing in the zone of a high-speed thermal process. Research on the influence of the parameters of a high-speed thermal process on the change in the structure of 8KHF steel (GOST 5950-2000 Russia, standard PN/H 85023 brand NCV1 Poland) was fulfilled. It allowed studying the nature of the change in the microstructure depending on short-term heating to various temperatures and rapid cooling. As a result, critical points of the beginning and the end of structural transformations during heating were determined. Research on thermal processes in a high-speed thermal process made it possible to establish regularities of influence of cutting speed, source speed, contact area, coolant properties and heat transfer coefficient on the temperature and rate of thermal processes in surface layers, as well as their impact on the depth of heating to a certain temperature. The study also allowed us to show the relationship between temperature and rates of heating and cooling. The solution to this problem, taking into account the action of the cooling fluid, gives the opportunity to bring the picture of the development of thermal processes closer to real conditions and makes it possible to reasonably predict the structural state of the surface layer of wedge-shaped parts made of 8KHF steel under various conditions of a high-speed thermal process.

Acoustic Modelling of Sport and Hunting Shooting Ranges in the Aspect of Shaping Noise Emissions Into the Environment
Authors: Boczkowski Arkadiusz
Published: August 2020

The article deals with the problem of acoustic modelling of sport and hunting shooting ranges for the purposes of carrying out acoustic impact assessments on the environment. The fashion for recreational shooting and the dynamic development of shooting ranges resulted in conflict situations between the shooting range and the residents. Increasingly, the condition for allowing the shooting range to be used is to carry out an acoustic analysis to confirm the lack of noise nuisance. Therefore, it is necessary to develop guidelines for acoustic modelling of shooting ranges, taking into account their purpose and types of shooting axes. Each of the shooting axes is designed for a different type of shooting and thus has different acoustic characteristics. In the article, the author presents a method of modelling noise emissions from the shooting range on the example of one of the popular shooting competitions which is the hunting trap. First, acoustic measurements of the unit noise source related to the firing of shots by a firearms shooter were made. Then the directional characteristics of this source were determined, the shooting axis of the “hunting trap” type was modelled during a typical shooting competition and its directionality was determined. Then, on the example of a specific shooting range, the possibility of using the results to analyse the propagation of noise into the environment during typical shootings on the trap axis was presented.
Analytical Tools in an Industrial Enterprise

Published: August 2020

Manufacturing companies operate on data from production, operation and trade. The strategy of creating and collecting data at the centre of production processes has significantly improved in recent years. Manufacturers are now collecting and storing vast amounts of data from their manufacturing facilities, both online and offline, from multiple geographic locations and with a growing number of separate data repositories. The design of workplaces and products continues to migrate from paper to the computer, where analysis accuracy, visualization, and collaboration utilities allow designs to be realized much faster and better than ever before. As the pace of this development accelerates with the increased capabilities of the software design tools, less time is spent on physical prototyping, allowing for shortened time-to-market for new products. Ergonomists, who in the past used the physical prototypes to perform human factors analyses, are now challenged to move the analysis into the virtual domain using new tools and methods. Usability, maintainability, physical ergonomic assessments, psychological perception, and procedural training are some of the human factors issues that might benefit from analysis prior to the first physical incarnation of the design.

Post-Industrial Areas Management, Evaluation of the Area’s Suitability for Redevelopment – Case Study
Authors: Michalski Krzysztof
Published: August 2020

The transformation of the Polish economy during the period of its transformation from a planned socialist economy into a market economy resulted, among others, in the emergence of a large number of post-industrial areas which are no longer used. Located often in developed urban areas, with many disadvantages such as contamination or unstable ownership status, they are not of interest to investors. Exploiting the potential they undoubtedly have would in many cases require the investment of considerable resources, but in order for these to be allocated to the investment, the investor expects to gain complete knowledge of the character and specificity of the place. The article is an example of a preliminary analysis of a selected post-industrial area, which helps to outline the direction of future area redevelopment.

Published: August 2020

The article examines the influence of migration processes on the formation and development of production capacities of countries. It is emphasized that population migration significantly affects the social and economic indicators of the country; under such influence, they can have both positive and negative trends. The article presents the main positive and negative consequences of population migration for donor countries, recipient countries, and for migrants themselves. It is proved that one of the most popular and promising is educational migration, which, under certain favorable circumstances, makes it possible to form highly qualified personnel, deepen international cooperation between higher education institutions of different countries, and strengthen the joint use of educational and scientific potential. The attention is focused on the fact that Ukraine today acts as a donor country and a leader in the number of young people who travel to study in Poland. It is indicated that in order to effectively regulate migration processes by the state, it is appropriate to ensure interaction between higher education institutions of different countries, namely, in the sphere of: a double-degree program, foreign internships, and holding joint international conferences. Using the example of Ivano-Frankivsk National Technical University of Oil and Gas and Ternopil National Economic University, it is shown how such interaction is implemented in practice and its consequences. The conclusions are based on the fact that educational migration is one of the most favorable types of migration. With its proper control by the state, it is possible to stimulate the development of the production industry in countries and improve social and economic indicators.

Fourier Variant Homogenization of the Heat Transfer Processes in Periodic Composites
Authors: Wierzbicki Ewaryst , Kula Dorota , Wodzyński Łukasz
Published: August 2020

The well-known parabolic Heat Transfer Equation is a simplest recognized description of phenomena related to the heat conductivity in solids with microstructure. However, it is a tool difficult to use due to the discontinuity of coefficients appearing here. The purpose of the paper is to reformulate this equation to the form that allows to represent solutions in the form of Fourier’s expansions. This equivalent re-formulation has the form of infinite number of equations with Fourier coefficients in expansion of the temperature field as the basic unknowns. The first term in Fourier representation, being an average temperature field, should satisfy the well-known parabolic heat conduction equation with Fourier coefficients as fields controlling average temperature behavior. The proposed description takes into account changes of the composite periodicity accompanying changes in the variable perpendicular to the surfaces separating components, concerning FGM - type materials and can be treated as the asymptotic version of Heat Transfer Equation obtained as a result of a certain limit passage where the cell size remains unchanged.

Authors: Sulym Heorhiy , Mikulich Olena , Shvabyuk Vasyl’
Published: August 2020

The paper presents studies on the application of the boundary integral equation method for investigation of dynamic stress state of foam media with tunnel cavities in Cosserat continuum. For the solution of the non-stationary problem, the Fourier transform for time variable was used. The potential representations of Fourier transform displacements and microrotations are written. The fundamental functions of displacements and microrotations for the two-dimensional case of Cosserat continuum are built. Thus, the fundamental functions of displacement for the time-domain problem are derived as the functions of the two-dimensional isotropic continuum and the functions, which are responsible for the effect of shear-rotation deformations. The method of mechanical quadrature is applied for numerical calculations. Numerical example shows the comparison of distribution of dynamic stresses in the foam medium with the cavity under the action of impulse load accounting for the shear-rotation deformations effect and without accounting for this effect.

Authors: Krilek Jozef , Kuvik Tomáš , Kováč Ján , Melicherčík Ján
Published: August 2020

The paper focuses on measuring and evaluating the impact of selected technical and technological factors -the height of adjustable guides and stretching force - on the side deflection of the saw band of a joinery band saw. There is a detailed description of the ways the side deflection can be measured. In order to find out the intensity of the stretching force was used portable tension meter SANDVIK 5000, enabling to check the tensile stress in the saw blades of a gang saw or in the saw bands of a band saw. The actual experiment was conducted on a joinery band saw, at the cutting rate vc = 15 m·s-1. The results of the measurements confirmed the theoretical assumption of the impact of the selected technical and technological factors on the stability of the saw band, where the side deflection decreases with increasing stretching force and increases with increasing height of the guides. The stability of the saw band affects the quality of the surface to be treated, thus saving the cost of machining the workpiece and making work productivity more efficient.

Authors: Janczyszyn Jerzy A. , Domańska Grażyna , Stanisz Przemysław
Published: August 2020

The possibility of preparing fission chambers for the experimental determination of subcriticality without time-consuming corrections has been presented. The reactor detectors set consists of monoisotopic chambers. Each chamber is intended for a specific position in the system. Individual weights, rated a priori for all detectors in their positions, allow for quick calculation of whole system subcriticality. The inconveniences related to the spatial effect are minimized. This is achieved by computational simulation of the area method results, for each detector position and all possible fissionable and fissile nuclides. Next, one nuclide is selected, specific for the given position, presenting the smallest difference from the MCNP KCODE precisely estimated kkcode. The case study is made using the model of VENUS-F core.
P4TC—Provably-Secure yet Practical Privacy-Preserving Toll Collection
Authors: Fetzer Valerie , Hoffmann Max , Nagel Matthias , Rupp Andy , Schwerdt Rebecca
Published: August 2020

Electronic toll collection (ETC) is widely used all over the world not only to finance our road infrastructures, but also to realize advanced features like congestion management and pollution reduction by means of dynamic pricing. Unfortunately, existing systems rely on user identification and allow tracing a user’s movements. Several abuses of this personalized location data have already become public. In view of the planned Europeanwide interoperable tolling system EETS and the new EU General Data Protection Regulation, location privacy becomes of particular importance.

In this paper, we propose a flexible security model and crypto protocol framework designed for privacy-preserving toll collection in the most dominant setting, i.e., Dedicated Short Range Communication (DSRC) ETC. A major challenge in designing the framework at hand was to combine provable security and practicality, where the latter includes practical performance figures and a suitable treatment of real-world issues, like broken onboard units etc. To the best of our knowledge, our work is the first in the DSRC setting with a rigorous security model and proof and arguably the most comprehensive formal treatment of ETC security and privacy overall. Additionally, we provide a prototypical implementation on realistic hardware which already features fairly practical performance figures. An interaction between an onboard unit and a road-side unit is estimated to take less than a second allowing for toll collection at full speed assuming one road-side unit per lane.
The level of knowledge of family doctors on climate change

Published: August 2020

Currently, the question is no longer if the climate is changing because the magnitude and speed of climate change, but it is a fact confirmed by many teams of specialists. It has become a hotly debated topic for politicians, businessmen, environmentalists, society and media. We designed a pilot study using a questionnaire in order to identify the level of knowledge, skills and practices of family physicians regarding the impact of their work on the environment and climate change. The questionnaire included 42 items regarding socio-demographic data, doctors’ knowledge regarding climate change, global warming, heatwave, thermal stress, the activity performed by doctors during the heat wave and the information received by doctors about heatwave periods. The research results confirm the hypothesis that doctors have some knowledge about the phenomenon of climate change, but there are some gaps and misunderstandings of the cause and effect of the phenomenon, as well as the methods to combat them. There is a need for additional training and guidance of physicians on the relationship between climate change, global warming and population health.

Revelations. The Wild Duck Versus Hamlet
Authors: Orăşanu Brînduşa
Published: August 2020

The present work compares two literary figures, imagining the internal conflict of each, in connection to a secret. In Hamlet’s case (Hamlet by W. Shakespeare), it is a traumatic impossibility to reveal a secret that leads to his death, while for Gregers (H. Ibsen’s The Wild Duck), the opposite occurs, his inability to keep a secret leads directly to the death of another character. In this work the secret is viewed as the conscious concealment of content, while the motives for keeping or disclosing it at any cost are unconscious.
Short-term comparative results of segmental resection versus radical resection in two patients with myxofibrosarcoma of the limbs - case series
Authors: Iordache Sergiu-Andrei , Şerban Bogdan , Vlad Andreea , Cursaru Adrian
Published: August 2020

Introduction: Myxofibrosarcoma is a rare subtype of soft tissue sarcoma with a locally infiltrative behavior and ability to determine distant metastases.

Materials and methods: We presented two myxofibrosarcoma cases who benefited from segmental or radical resection.

Management and outcome: In the case of the 80-year-old woman, with grade 3 myxofibrosarcoma, we practiced radical surgery with scapulohumeral disarticulation followed by adjuvant radiotherapy.

The therapeutic option for the 77-year-old man with grade 2 myxofibrosarcoma was segmental resection followed by adjuvant radiotherapy. After three months, the patient was in a good clinical condition with no sign of local recurrence, but with the presence of pulmonary metastases for the patient who benefited of segmental resection.

Discussion: The radical resection had better short-term results, with no local or distant metastases at three months after surgery, although the tumor had a higher grade (G3), compared to segmental resection practiced for a lower grade tumor (G2), in which case the patient developed pulmonary metastasis at three months follow up.

Conclusion: Myxofibrosarcoma represents a challenging situation regarding the management due to its unpredictive clinical course. Our cases raised the following question: should we consider treating it more aggressively in order to obtain good local control and reduce the risk of metastasis?

Published: August 2020

Introduction: The aim of the study was to report the clinical and functional outcomes in patients undergoing limb salvage with various reconstruction techniques in primary malignant bone tumor.

Materials and methods: This study was performed between 2011 and 2018 on 52 patients with primary malignant bone tumors admitted to the Department of Orthopaedics and Traumatology of University Emergency Hospital, Bucharest. All the patients underwent surgical treatment (resection-reconstruction technique) followed by oncologic therapy. The mean follow-up was 3 years and 8 months and the minimum follow-up was 12 months.

Results: The best results were obtained in patients in whom resection of the tumor followed by reconstruction was possible, without affecting the adjacent joint through arthrodesis or arthroplasty. These patients had an average MSTS score of 75.2%. The patients who underwent reconstruction procedures by endoprosthesis also had good results with an average MSTS score of 72.3%, while patients with arthrodesis obtained rather modest results – the average MSTS score being 67.3%. When taking into consideration the location of tumors, the best MSTS scores were obtained in patients with tumors of the distal radius – 80%, followed by femoral and humeral diaphysis – 75.6%, distal femur – 75.2%, proximal femur – 73.3%, proximal humerus – 72.3%, tibial diaphysis – 72.2%, distal tibia – 70% and proximal tibia 68.7%.

Conclusions: The orthopedist must judiciously chose the surgical technique, taking into consideration the anatomical particularities and the needs of the patient. Given the functional results and the emotional acceptability, reconstruction with tumor prosthesis represents the first option.
Trauma of the pancreas. A hidden disaster
Authors: Slavu Iulian , Tulin Adrian , Braga Vlad , Enciu Octavian , Păduraru Dan , Socea Bogdan , Alecu Lucian
Published: August 2020

Due to its anatomical position, traumatic lesions of the pancreas are rare and difficult to diagnose. Diagnosis time is paramount as an increase in duration translates into an increase in morbidity and mortality. Duct lesions are hard to identify on CT, ERCP being the investigation of choice but it is difficult to obtain as it requires highly specialized staff and equipment. Intraoperative macroscopic and palpatory evaluation of the pancreas in a trauma patient should be elective no matter what other lesions are present. The treatment is mainly dictated by this evaluation and is defined as it follows: stage I and II usually require a conservative approach; stage III, IV, and V usually imply resection of the pancreas although recent advances in conservative management have been made through ERCP and pancreatic duct stenting. In these stages, intraoperative evaluation should ensure the ampulla is intact if the head of the pancreas is not resected. Serum amylase and lipase levels do not offer a concrete direction towards a pancreatic lesion. Currently, there is no standard surgical treatment for these stages thus making intraoperative evaluation mandatory. One must remember that post-traumatic pancreatitis exists, which becomes apparent days after the accident.

Published: August 2020

Objectives: Gout is the most common inflammatory arthritis of the 21 century, but is still frequently misdiagnosed. This review aims to provide guidance for gout management in clinical practice, which includes the diagnosis, treatment of acute episodes, but also long-term therapy to reduce serum urate, as well as lifestyle changes and prevention of recurrent episodes.

Design: Systematic review without meta-analysis.

Methods: We have systematically searched Google Scholar, PubMed, and all relevant worldwide guidelines to identify and select clinical guidelines for gout. We have included eligible gout articles according to predefined inclusion and exclusion criteria after selecting titles, abstracts and full texts. The characteristics of the recommendations reported in the guidelines included were extracted and analyzed.

Results: We selected 27 eligible papers and tried to facilitate the identification of recommendations for the treatment of gout in the acute phase, but also in the chronic phase. The recommendations were detailed and explained during this extensive review.

Conclusions: Despite the availability of effective serum urate reduction therapies, overall gout management is poor. Achieving therapeutic goals is often low both at the initiation of therapy and in long-term treatment. Optimal strategies for managing gout are necessary in both acute and chronic gout flames in patients who are prone to the development of this pathology.

Published: August 2020

By determining the prevalence of postural disorders among eighth grade school students it is possible to indicate the state of these disorders at the end of the elementary school level of education, and compare it to the results obtained by applying corrective treatments on high school students. Thus, the aim of the research was to determine the prevalence of postural disorders among eighth grade school children. The research was carried out on a sample of 101 eighth grade students of both genders, aged 14. The photometry method was used to determine the presence of any postural disorders. The research results indicated that a proportionally statistically significant large number of participants with postural disorders were identified. Of the total number of participants, 60.4% had postural disorders, the most prevalent of which was flat back (22.8%), kypho-lordosis, (20.8%), lordosis (9.9%) and kyphosis (6.9%). Analyzed in terms of gender, the percentage of the girls with postural disorders is statistically significantly greater than that of the boys. Due to the large number of children with postural disorders, the recommendation is that the evaluation of the postural status of students should take place not only at the elementary school age, but also at the high school age. In addition, evaluation alone is insufficient, and exercise programs to correct postural disorders are required as well.

Authors: Kavese Kambale , Phiri Andrew
Published: August 2020

A provincial analysis of Okun’s law in South Africa is provided in this article from 1996 to 2016. Empirically, we rely on the nonlinear autoregressive distributive lag (N-ARDL) model whilst the Corbae-Ouliaris filter is used to extract the ‘gap’ variables required for our regression estimates. Okun’s law is found to be significant hold in the long-run exclusively for the Western Cape and Kwa-Zulu Natal provinces whereas the remaining provinces partially display significant short-run effects. Our sensitivity analysis in which panel N-ARDL estimations for all provinces finds insignificant long-run Okun effects for the country as a whole, whilst validating the relationship only in the short-run. Our study hence advises that the epicenter of policy efforts in addressing the country’s high unemployment and low economic growth dilemma should be concentrated at a provincial level.

Published: August 2020

Subject. I consider the price policy of the State in conditions of domination of extractive industries, natural monopolies, and financial uncertainty in the economy.
Objectives. The purpose is to provide a modern concept of price as a market instrument, where prices act as objects of management, financial and economic regulators, and tools to manage the economy.
Methods. I employ methods of economic analysis and synthesis, comparison, scientific abstraction, and other methods of scientific knowledge.
Results. The paper critically examines the State policy in the field of pricing, and determines the specifics of price regulation for natural monopolies’ products, for the purpose of effective functioning of competitive markets, decline in prices, and influence of ruble exchange rate dynamics on wages, pensions, benefits and payments, as well as on relationships between domestic and world prices under financial uncertainty of commodity markets.
Conclusions. The main goal of the State pricing policy should be the development of an economic mechanism for its implementation as a means of direct increase in the Russian economy efficiency, rather than a focus on domestic resource-based industries as drivers of its development. Government regulation and financial impact on prices, as well as other forms of interference with market pricing, should encourage and expand healthy competition in the form of subsidies and subventions to new, but yet weak producers in the monopolized sector; subsidize substitutes for products manufactured by monopolists; subsidize the costs of import-substituting and export-oriented enterprises, etc.

Geology and Structural Description of Shakrok Anticline; Northern Iraq
Authors: Ahmed Sally Hussin , Salman Mahmood Abd ALAmeer
Published: August 2020

The studied area is a part of the Arabian plate located within the High Folded Zone of the Zagros Fold-Thrust Belt in northeastern Iraq (Kurdistan Region). The Study area deals with the Shakrok Anticlines is located between Safin Mountain and Sork Mountain. These structures are formed during the Alpine Orogeny in Cretaceous-Tertiary period. Generally, the folded structures are trending NW-SE direction which is parallel to the main Zagros Orogenic trends.

The exposed stratigraphic succession of the studied area that represented by 4 formations deposited from the Early Cretaceous which are Shiranish, Aqrah, Bekhme and Qamchuqa formations. Shakrok Anticline are asymmetrical, double plunging and verging toward northeast. This establishes that Merawa is a Tertiary continuation part of Cretaceous Shakrok Anticline, but there is a deflection in the direction of the fold axis that affected the Merawa Anticline due to the effect of strike slip fault addition to Lineament. Shakrok Anticline with Cretaceous successions formed due to the effect of Cretaceous and Tertiary folding phases. But Merawa Anticline with Tertiary succession that formed due to the effect of Tertiary folding phases.

The high stress and intensity of the major fault on the southwestern limb rotated and overturned Tertiary successions and changed its dip toward NE.

The differences in fold geometry, fold axis, axial surface, and curvilinear hinge imply that the structure formed as a result of two folding phases & lateral growth of folds that developed by changing the direction of the compressional tectonic processes due to Alpine Orogene of Zagros. The fold axis of Shakrok Anticline rotated 16o in anticlockwise trend from Merawa to Sork anticlines. Because of anticlockwise rotation of the Arabian plate due to its collision with Iranian and Anatolian plates.

The primary objective of this study was to investigate the current status of water-quality conditions and assessment it in the Tigris River, Baghdad, Iraq, and to determine how those conditions are changing over time of pollution if any. A series of Hydrochemical tests were carried out to ascertain the influence of major Cations and Anions, Total Dissolved Solids (TDS), Electrical Conductivity (EC) and Potential of hydrogen (pH) on the quality of water. To assess the environmental pollution of the study area: 34 water samples were collected along Tigris River from north to south Baghdad City; 17 on January 2019 and 17 on April 2019. Result of the test were compared with the World Health Organization standards, and showed that all the ions in addition of EC and TDS are within their acceptable limits, except for samples number 7 and 16where Sulfate concertation was above the acceptable limits. Therefor the Tigris River water in most of the study area is acceptable for all kinds of consumption. The most common water type in the area was Ca Na Mg- SO4 Cl HCO3 in January 2019 and Na Ca Mg- SO4 Cl in April 2019.
The Issues of Residential House Systems and How to Make It More Sustainable Systems
Authors: Ahmad Ahmad R.
Published: August 2020

This paper highlighted a set of issues facing the residential house system and makes it unsustainable systems including: high energy consumption, high water demand, waste generation, and carbon dioxide emissions. The boundaries, inputs and outputs of residential house systems are displayed in detail and illustrated by modeling these systems for the purpose of understanding the relationships and interactions between these inputs and outputs and components of these systems. Thus, presenting a range of strategies that can be implemented to make residential house systems more sustainable and reduce the negative impacts of these systems on the environment and other sources such as water, energy and non-renewable resources to a minimum level.
Comparison Some Robust Regularization Methods in Linear Regression via Simulation Study
Authors: Ajeel Sherzad M. , Hashem Hussein A.
Published: August 2020

In this paper, we reviewed some variable selection methods in linear regression model. Conventional methodologies such as the Ordinary Least Squares (OLS) technique is one of the most commonly used method in estimating the parameters in linear regression. But the OLS estimates performs poorly when the dataset suffer from outliers or when the assumption of normality is violated such as in the case of heavy-tailed errors. To address this problem, robust regularized regression methods like Huber Lasso (Rosset and Zhu, 2007) and quantile regression (Koenker and Bassett ,1978] were proposed. This paper focuses on comparing the performance of the seven methods, the quantile regression estimates, the Huber Lasso estimates, the adaptive Huber Lasso estimates, the adaptive LAD Lasso, the Gamma-divergence estimates, the Maximum Tangent Likelihood Lasso (MTE) estimates and Semismooth Newton Coordinate Descent Algorithm (SNCD ) Huber loss estimates.
