THEORETICAL AND METHODOLOGICAL BASES OF PSYCHOLOGICAL EXAMINATION IN CASES RELATED TO THE INVESTIGATION OF EMERGENCY SITUATIONS
Authors: Arefina N.
Published: June 2020

The article analyzes the current state of the practice of investigating incidents related to the implementation by a person of control of complex automated mechanisms. Attention is focused on the insufficient use by the judicial and investigative authorities of special psychological knowledge and relevant developments in the investigation of such cases.

Based on the analysis of special psychological literature, as well as the experience of applying special knowledge in the field of examination, the psychological aspects that make up the human factor are outlined. The subject of psychological examination in cases of investigation of incidents related to the implementation of human control of complex automated mechanisms is disclosed. The nuances of the functioning of mental processes, properties and states of a person are noted, which can influence his ability, under extreme circumstances, to correctly assess the situation (or its individual elements), make the right decision and implement it. Along with this, external factors are noted that can have a significant impact on a person’s ability to make the right decision and implement it.
TO THE QUESTION OF DEFINING THE CONCEPT OF FORGING ART WORKS
Authors: Polishchuk I. , Koloniuk V.
Published: June 2020

The article consistently discusses basic terminology related to the forgery of works of art.

In particular, the phenomenon of attribution is explored, which means the definition of authenticity, authenticity of a work of art, its author, place and time of creation.

The concept of the original, which is generally referred to as the basis for reproduction, copying and reprocessing, is explored. Attention is drawn to the fact that in Ukrainian, law this term (original) is not defined, but it can be identified with the phrase “material object in which the work is embodied”. It is determined that the legislator uses the term work, axiomatically considers that the material object in which this work is first embodied, and is the original. It is stated that the legislator does not define the term work, but interprets such concepts as a work of architecture; a work of fine art; a work of applied art. In summary, it is important in this context to understand the distribution of copyright and ownership of the tangible object in which the work (original) is embodied. Issues of the category of “original” in engraving are covered.

Different levels of copy concept (doublet, replica, repetition) are considered.

It is established that the concept of art is the variant most similar to the derivative work in law, which is a creative alteration of another existing work without harming its protection. At the same time, the situation in which the variants of the work are performed by the author of the original, and when it comes to imitation, endorsement and shepherds, in which reference is made to already existing works of other persons, is delimited.

It has been found out that in addition to intentional fraud, there are many noncriminal reasons why a work of art may not be attributed to its original author.

On the basis of the conducted research, the author’s definition of fake work of art, which is a material object in which the work is embodied, the author (producer) and/or the time and place of creation (manufacture) of which is untrue, but was presented as such, and this is refuted by evidence that is beyond doubt – a complex art and technology – technological expertise, taking into account relevant research on provenance and ownership history.

EXPERT POSSIBILITIES OF FORENSIC CYTOLOGY INVESTIGATION IN FORENSIC EXAMINATION OF MATERIAL EVIDENCE
Authors: Starovoitova R. , Lichman T.
Published: June 2020

The article presents the history of the development and implementation of forensic cytological research methods in the practice of conducting forensic examinations of material evidence in the forensic examination bureau of Ukraine. The modern possibilities of forensic cytology methods for solving investigative issues in solving crimes against human life and health are shown in the article.

Due to the fact, that the object of study of expert cytologists and expert geneticists is the same substance, namely, nuclear cells of different tissues and organs, blood leukocytes, epithelial cells of saliva, vagina, rectum, sperm, and cells of the outer root vagina hair – forensic cytological studies necessitate the preservation of nuclear cells for further genetic analysis. To this end, the staff of the Forensic Cytology Department of the Main Bureau of Forensic Examination developed a method for the preparation of cytological preparations using an ultrasonic water bath, which allows increasing the number of cellular elements extracted.

At the same time, the specialists of the Odesa Regional Bureau of Forensic Examination introduced a technique for conducting molecular genetic analysis of nucleated cells in cytological preparations. Such techniques allow, even with a very small amount of biomaterial, to answer most of the questions posed by the investigator to the expert.

The effect of plastic waste and elemental sulfur additives on chemical and physical properties of bitumen
Authors: Ashjari M. , Masoud Kandomal S.
Published: June 2020

In this study we describe the modification of bitumen for obtaining better chemical and physical properties. For this goal, we added sulfur or plastic waste in different percentages to the bitumen matrix. The effect of sulfur ratio in the range of 20-40% (w/w) and plastic waste ratio in the range of 2-5% (w/w) was investigated on the softening point, penetration, tensile factor and loss of weight of bitumen. The obtained data confirmed the improvement in chemical and physical properties of bitumen in the presence of plastic waste and sulfur additives. The results showed that tensile factor of bitumen decreases from 1020 mm to 820 mm and 980 mm after addition of 30% of sulfur and 3% of plastic waste, respectively. On the other hand, the best penetration was obtained in the presence of 30% sulfur and 3% plastic waste, respectively. Finally, we suggest the application of sulfur and plastic waste as two important additives for bitumen modification.

Late Quaternary history of Lammefjorden, north-west Sjælland, Denmark
Authors: Bennike Ole , Roll Jakobsen Peter , Walløe Hansen Jakob
Published: June 2020

Lammefjorden is a reclaimed fjord in north-west Sjælland, Denmark. Sediment cores from the area were collected to study its development after the last deglaciation, in particular the sea-level history. Late glacial and Early Holocene lake and bog deposits occur below marine deposits. Sparse late glacial fossil assemblages indicate tree-less environments with dwarf-shrub heaths. Early Holocene deposits contain remains of Betula sec. Albae sp. and Pinus sylvestris, which indicate open forests. The wetland flora comprised the calciphilous reed plant Cladium mariscus and the water plant Najas marina. Marine gyttja from basins is characterised by sparse benthic faunas, probably due to high sedimentation rates. In some areas, shell-rich deposits were found, with large shells of Ostrea edulis, indicative of high summer temperatures, high salinity and strong tidal currents. A marine shell dated to 6.7 cal. ka provides a minimum age for the marine transgression of Lammefjorden.

Ecological monitoring system of the atmosphere
Authors: Rybak V. A. , Ryabichina O. P.
Published: June 2020

The research is targeted at the development and testing of a hardware-software system for environmental monitoring of atmospheric air in real time. The relevance of creating the system is substantiated in the article where it is shown that one cannot obtain operational data on the degree of atmospheric air pollution using available means, although this information is important for the population of large cities and industrial centers. The results of the creation and use of the automated system for monitoring atmospheric air using the modeling of transfer of pollutants are presented. The system was based on a hardwaresoftware complex consisting of a microcomputer, pollution sensors, a wireless communication module, and an unmanned aerial vehicle. Real-time pollution indicators are processed in order to build up-to-date maps, including to provide the opportunity to choose the optimal route taking into account the adverse effects of pollution. The developed mobile application provides the opportunity for the end user to receive information on-line and make forecasts based on the data on wind strength and direction in the short and medium term. The OND-86 methodology, which is mandatory in the Republic of Belarus, was chosen as the main model for the transfer of pollutants in the air. Information about the strength and direction of the wind for building forecasts is taken from open Internet sources of weather data. Using real data on the mass of emissions, a map of the planned concentration is constructed, which is scattered in proportion to the distance from the source of the emission, taking into account the strength and direction of the wind. The forecast obtained in this way can be used to select the optimal route, optimize traffic flows and organize actions in emergency situations associated with leakage and emissions of harmful substances.
Structure and morphology of CrSi2 layers formed by rapid thermal treatment
Authors: Solovjov J. A. , Pillipenko V. A. , Gaiduk P. I.
Published: June 2020

The formation of chromium disilicide layers on n-type single crystal silicon substrates (111) during rapid thermal annealing in heat balance mode by the methods of Rutherford backscattering, X-ray diffraction and transmission electron microscopy of cross sections was investigated. Chromium films of about 30 nm thickness were deposited by magnetron sputtering of a chromium target with argon ions onto silicon substrates at room temperature. The rapid thermal treatment was carried out in a temperature range of 200 to 550 °C in a heat balance mode by irradiating the substrates backside with a non-coherent light flux of quartz halogen lamps in a nitrogen ambient for 7 s. It was established that hexagonal phase of chromium disilicide formation with grain size of 150–300 nm occurs in a threshold manner when the temperature of rapid thermal treatment exceeds 400 °C. At the same time, there are strong changes in the films surface morphology and surface roughness, and a silicide-silicon interface occur. In this case the wavy film surface morphology practically repeats silicide-silicon interface morphology (the surface exactly replicates the interface). The mechanism of CrSi2/Si interface structure roughness formation based on consideration of Kirkendall effect and deformation-stimulated diffusion of vacancies is proposed and discussed. The research results of the structure and morphology of CrSi2 layers on silicon are well-correlated with the results of the Schottky barrier electrophysical measurements. The results obtained can be used in microelectronics for forming rectifying contacts and interconnects metallization for integrated circuits, as well as for thermoelectric and optoelectronic applications.
Mathematical model of speech signal leakage channels during discrete-quantified conversion
Authors: Zheleznjak V. K. , Lavrov S. V. , Baranouski M. M. , Filipovich A. G.
Published: June 2020

The purpose of the article is to estimate the leakage channel of a discrete-quantized speech signal with amplitude-pulse modulation. Discrete-quantized analog-to-digital conversion of signals in the article is considered by the example of pulse-amplitude modulation. Development of mathematical model of speech signal leakage channels during discrete-quantified conversion is based on the spectral representation of periodic signals by Fourier series. A periodic pulse train of triangular shape as a measuring signal is proposed. Measuring signal of triangular shape has an advantage over a harmonic signal in the process of quantization noise extraction because it allows one to achieve higher accuracy during signal processing. To evaluate the channel security caused by amplitude-pulse modulation, a harmonic signal is used, which is generated from a periodic pulse sequence of a triangular shape by the Fourier transform method. As a result of constructing the spectrum of the amplitude-pulse modulated signal, it was found that for each harmonic component of the spectrum corresponding to the spectrum of the periodic sequence of pulses, side components corresponding to the spectrum of the modulating signal appear. This side components, together with the low-frequency component in the band of the speech signal, form an information leakage channel. The presence of source modulating signal in the amplitude-pulse modulated signal spectrum allows one to digest the security of the leakage channel of the speech signal with amplitude-pulse modulation by the low-frequency component of the modulating signal. The materials presented in the article are original and can be used in assessing the security of leakage channels of speech signals converted into digital form. In addition, the results obtained allow further studies of the security of speech signals during their inverse transformation from digital to the original signal.

The system consisted of a modified septic tank equipped with a disinfection chamber inside the tank. Solar radiation was collected as a heat source for heating and disinfection. The system could achieve high removal efficiencies of total chemical oxygen demand (TCOD), 5-day biological oxygen demand (BOD5), total solid (TS), and total volatile solid (TVS) of 97%, 94%, 91% and 96%, respectively. The inactivation efficiencies of E. coli and total coliforms in the SST were about 2.2 log reduction. The increased temperature inside the septic tank could help to inactivate pathogens and reduce the environmental issues related to conventional fecal sludge management. In turn, this improved the water quality of groundwater and surface water and minimize health risks. Influence of operational conditions including organic/nutrient loading rate and ratio between TCOD and TKN in the black water on the performance of the SST were discussed.

Underground travel time estimation for macro simulation models, on the example of the first line in Warsaw
Authors: Bauer Marek
Published: June 2020

In this paper, the author’s model of underground travel time prediction was presented. The structure of the model can be used to estimate the travel time of any underground line in the planning phase. The model takes into account the length and the variability of running time between stations and stopping time at these stations. Partial models of average running time depending on the length of the sections – for six periods of the working day, developed on the basis of measurements on the first underground line in Warsaw were presented. Similar models for the estimation of the standard deviation of running time were also presented. Stopping times for three types of stations, varying in terms of the average stopping time and location of the station in relation to the city center were estimated. Paper presents also a practical example of the use of the model: evaluation of the impact of additional stations on the travel time on the underground line in Warsaw.
Analysis of 50/70 foamed bitumen properties in the aspect of its utilization in mineral-bitumen mixtures
Authors: Chomicz-Kowalska Anna
Published: June 2020

The aim of the study was to analyze the properties of foamed bitumen produced from 50/70 bitumen in terms of the assessment of its usefulness to the road construction materials. In order to improve the foaming parameters the synthetic wax Fischer-Tropsch (FT) in an amount of 1.0%, 2.0% and 3.0% was used. Bitumen binder parameters were evaluated before and after the foaming process. The basic parameters were evaluated (before the foaming process): penetration, Fraass breaking point and softening point. The bitumen foam parameters were measured at the foaming water content (FWC) in the range from 1.5% to 4.0% with an increment of 0.5%. The tests allowed determining optimal application ranges for the FT and the FWC to produce asphalt at lower temperatures.

Recycled Asphalt Pavement (RAP) as a fully valuable component of the HMA mixes
Authors: Koźlarek Piotr
Published: June 2020

Currently produced HMA mixes have to meet a certain requirements for a finished product. European product standards and Polish technical guidelines contain all relevant regulations and requirements regarding HMA. Polish technical guidelines WT 2-2010 reduce also the maximum amount of RAP in HMA without taking into consideration the technical capabilities of asphalt mixing plants. There are two main methods to introduce the RAP into HMA at the asphalt mixing plant: cold and hot method. The most popular method in Poland is the cold method, where the cold RAP is added directly to the mixer. According to hot method the RAP is first preheated by using special heating drum, and then added to the mixer. Therefore, an attempt was made to prove, that the HMA with increased content of RAP can compete with HMA made of 100% virgin material. Two HMA mixes designated for traffic category 3 to 4 were selected for further tests, namely asphalt base and binder course. Four variants of every mixture type were made with 0, 15, 25 and 35% of RAP. The virgin added binder was the unmodified asphalt type 35/50. The research plan included testing of each mixture’s volumetric parameters, as well as, their performance-based and performance-related properties.

Published: June 2020

Paper presents preliminary findings from the research project Mobis which is aimed at developing a method of assessing safety of pedestrian road crossings by using video image analysis. Pedestrian and vehicle traffic has been recorded at a selected crossing site in Warsaw for 2 months, before and after installation of safety measures which included active signage and speed humps. Speeds of approaching vehicles were measured and vehicle-pedestrian conflict situations identified by using video analysis. Results indicate that both SignFlash active signage and speed humps reduce mean vehicle speed and have a positive impact on drivers’ behaviour.

Evaluation of efficiency of acoustic screen with gate
Authors: Pereta Karol , Janas Lucjan , Klich Rafał
Published: June 2020

One of the biggest problems of traffic noise protection is the proper design of noise barriers, their location, length and height. An experimental and analytical efficiency method of traffic noise protection against traffic noise, in the case of a single-family building, has been presented in this paper. The efficiency of this screen has been evaluated by an indirect method. In this case research survey on site has been made. The calculations have been made with the use of three methods. The results of measurements and calculations have been compared. A low efficiency acoustic screen has been demonstrated, whereas its low efficiency mainly resulted from the low height and length. On the basis of the interviews with residents, it can be said that the construction of screens, even those of low efficiency, makes sense.
Evaluation of prefabricated blocks of flats through the Real estate market point of view
Authors: Zyga Jacek
Published: June 2020

The market of flats located in buildings of prefabricated blocks in Lublin, on the background of the rest of flats, is described in presented essey. The analysis of the variables included in the unit prices of flats (from the period of the years 2005-2013), located in multi-family blocks, completion of which was contained in the years 1962-1991 and the design was a variant of construction of prefabricated elements or another. Comparative analysis was performed separately for separate zones as well as for the city of Lublin. The comparison of transactions in the whole of the city showed that in most of the periods compared, average unit prices of flats, located in prefabricated buildings, remained higher than other. On the other hand, during the year 2004 and for the years 2011-2013 (separately in different years), the average unit prices of flats in prefabricated buildings happened to be lower than the average prices of other premises. Statistical significance of differences between average unit prices in parallel subgroups (prefabricated buildings vs. buildings realized in other technologies) has been tested with Student's t-test. The comparison of two mentioned market segments demonstrates their small diversity, proving that the market evaluation of usefulness and safety of flats located in buildings of prefabricated blocks is different and much better than the evaluations of constructors.
Transverse reinforcement contribution in shear – remarks from experimental research
Authors: Rafał Ostromęcki
Published: June 2020

The results of research for transverse reinforcement contribution in shear are presented in the article. Tests were made on the single span, simply supported beams. Resistance gauges were used to measure the strain on the stirrups at points crossing the artificial crack, formed with the thin, greased plate. Basing on the constitutive law for the stirrups steel derived in test, the force in stirrups was invented VEd,s. Such an attitude allowed to compare the force carried by stirrups VEd,s with the actual shear loading VEd. In the performed test made the stirrups contribution was between 52 and 72% of shear force. It was also noticed, that longitudinal reinforcement carried some transverse force as well. This ability is usually neglected in shear theories.
The influence of longitudinal reinforcement on shear capacity of reinforced concrete members without shear reinforcement
Authors: Słowik Marta
Published: June 2020

In the paper, the influence of longitudinal reinforcement on shear capacity of reinforced concrete members without shear reinforcement is discussed. The problem is analyzed on the basis of the author’s own test results and tests results reported in the professional literature. It has been concluded that longitudinal reinforcement has an effect on shear capacity especially in members of shear span-to-depth ratio a/d < 2,5. The test results have also been used to verify standard methods of calculating the shear capacity in reinforced concrete members without shear reinforcement given in Eurocode 2, ACI Standard 318 and Model Code 2010.
