PSYCHOLOGICAL IMPACT OF QUANTIFIERS IN ADVERTISEMENTS
Authors: Ohiienko Kateryna
Published: November 2019

The article is devoted to comparative investigation of advertisements of one cosmetic company written in different languages, in particular, we analysed quantifiers in English and Ukrainian Avon brochures on the grounds of their polycode nature.
The analysis of recent publications allowed us to notice that the investigations of both advertisements and the category of quantitativity are based on different theoretical and practical principles.
Being guided by already existing classifications of quantifiers in English and Ukrainian by S. O. Shvachko, V. M. Kondratiuk, O. S. Ananieva, we displayed morphological, structural and combinatory possibilities of quantifiers, textual modifications of numeral combinations in English and Ukrainian advertisements. We suggested main models of quantifiers, emphasizing an important role and functions of units which express definite and indefinite quantity.
Morphologically quantifiers are represented not only by numerals, but also by nouns, pronouns, adjectives, adverbs, verbs, their situational and idiomatic combinations, and even mathematical signs.
The study of structural and combinatory possibilities of quantifiers also showed morphemes-quantifiers, the usage of quantifiers with specifiers, qualifiers and rhematizers, the structures like n-в-1 (n-in-1), where n>1, as well as word-combinations and phrases synonymic to this structure.
All described morphological, structural and combinatory possibilities of quantifiers have a rather significant psychological impact in advertisements, emphasizing the advantages of some cosmetic goods and calling for trust to them. Besides, language means are supplemented by visual, graphic and sometimes sensory (olfactory) ones, which strengthen the influence on the consumer.
CHANGES IN THE SEMANTICS OF LEGAL LEXIS IN THE INDO-EUROPEAN LANGUAGES (based on the materials, retrieved from the thesis paper “Formation of the legal terminological semantics in the Indo-European languages”)
Authors: Fedorova Anastasiia
Published: November 2019

The history of legal lexis dates back to the ancient times of ancient peoples. The study of legal language enables the reconstruction of Indo-European ritual-legal ancients at verbal, linguistic levels. Archaic societies had no legal culture, instead, the norms of customary law of ancient societies were referred to as “pre-law”, which included syncretism of law, religion, myth, poetry, and morality. The syncretic ritual and legal consciousness of the ancient peoples in the pre-state period and in the early state formations has its specific reflection in a language that receives such a definition as “the language of law”. The system of “language of law” of Indo-European peoples is partly outlined in today’s scientific survey by describing changes in the semantics of legal lexis in the Indo-European languages, based on the analysis of the distinguished evolutionary models of semantics (EMS) in the Germanic, Slavonic and Iranian languages. The evolutionary model of semantics is a method of inquiry and a procedural scheme for explaining the history of legal meaning. 79 EMS were distinguished during the research, showing the genesis of the meaning 'power', 'lord', 'to rule', 'law', '(religious) law', 'pledge', '(blood) feud', 'court', 'judge'. Using data of the distinguished EMS, that clearly shows the change in the semantic volume of a word, a specific type of change in the meaning of legal lexis in the lexical and semantic system of the Indo-European languages was identified for each EMS, namely, expanding, narrowing (specializing), amelioration or pejoration of the meaning of the word. The study found that quantitatively the semantic derivation of the Indo-European legal terminology most experienced the type of narrowing of the meaning of the word, which, according to the researchers, belongs to the semantic universals. Metaphorical and metonymic changes in the meaning in the legal lexis of the Indo-European languages were also highlighted, that will need further study.

Published: November 2019

The oviduct is a key organ responsible for ultimate oocytes maturation, transport of gametes, sperm capacitation, fertilization, as well as early embryo development. Its innermost layer, oviductal epithelium, represents a highly dynamic structure which undergoes changes in response to different physiological and pathological processes. Previously, the expression profile of genes involved in several important processes in porcine oviductal epithelial cells (OECs) during long-term primary in vitro culture. The present study further characterizes the porcine OECs model using Affymetrix microarray assay and it analyzes gene expression changes observed on the 7th, 15th and 30th day of culture. 25 genes belonging to “coenzyme metabolic process”, “cofactor biosynthetic process” and “cofactor metabolic process” GO BP terms were differentially expressed in culture. The most up-regulated genes were ALDH1L2, P2RX7, PANK1, ACSS2, SCD, AASS and PDK3. In contrast, several genes appeared to be significantly down-regulated, e.g. ACSL4 and HAAO. Considering the biological roles of the most regulated genes, it can be concluded that these changes may indicate the increased metabolic and proliferation activity of studied cells in primary in vitro culture.

Enhancement of in Vitro Developmental Outcome of Cloned Goat Embryos After Epigenetic Modulation of Somatic Cell-Inherited Nuclear Genome with Trichostatin A
Authors: Skrzyszowska Maria , Samiec Marcin
Published: November 2019

In this study, the effect of trichostatin A (TSA)-mediated epigenomic modulation of nuclear donor cells on the in vitro developmental potential of caprine somatic cell cloned embryos was examined. The enucleated ex vivo-matured oocytes were subzonally injected with adult ear skin-derived fibroblast cells exposed or not exposed to TSA (at a concentration of 50 nM). The experiment was designed on the basis of three different approaches to TSA-dependent modulation of donor cell-descended genome: before being used for somatic cell nuclear transfer/SCNT (Group I); immediately after activation of nuclear-transferred (NT) oocytes (Group II); or combined treatment both before being used for SCNT and after activation of NT oocytes (Group III). In the control Group IV, donor cell nuclei have not been treated with TSA at any stage of the experimental design. In TSA-treated Groups I and II and untreated Group IV, cleavage activities of cloned embryos were at the similar levels (80.6%, 79.8% and 77.1%, respectively). But, significant difference was observed between Groups III and IV (85.3 vs. 77.1%). Moreover, in the experimental Groups I and III, the percentages of cloned embryos that reached the blastocyst stages remarkably increased as compared to those noticed in the control Group IV (31.2% vs. 36.7% vs. 18.9%, respectively). In turn, among embryos assigned to Group II, blastocyst formation rate was only slightly higher than that in the control Group IV, but the differences were not statistically significant (25.8% vs. 18.9%). To sum up, TSA-based epigenomic modulation of somatic cell-inherited nuclear genome gave rise to increased competences of caprine cloned embryos to complete their development to blastocyst stages. In particular, sequential TSA-mediated modulation of both nuclear donor cells and activated NT oocytes led to improvement in the blastocyst yields of cloned goat embryos, which can result from enhanced donor cell nuclear reprogrammability.

Meat is an important part of the human diet since it provides several nutrients. However, the amount of these nutrients can differ according to several factors. With this in mind, the present research was designed with the main objective of evaluating the effect of production system of broiler chickens (industrial, range and organic) on meat quality. The physicochemical, chemical and nutritional characteristics were determined in breast and drumstick meat. The organic chickens presented the lowest amounts of fat and cholesterol and the highest amounts of protein. The colour was also influenced by the production system, where organic and range chickens had the highest values of redness in both cuts (breast and drumstick). In addition, the content of essential fatty acids (C18:2n-6 and C18:3n-3) and other fatty acids with high biological importance, such as eicosapentanoic acid (EPA; C20:5n-3), docosapentanoic acid (DPA; C22:5n-3) and docosahexanoic acid (DHA; C22:6n-3) were higher in organic samples compared to industrial or range chickens. The amino acids content did not vary with the production system. With regard to mineral contents, organic chickens had the highest values of iron in drumstick and significantly lower values of magnesium in both cuts than industrial chickens. On the whole, the meat of the organic chickens showed better nutritional characteristics than those produced in range or industrial conditions.
Subsurface tectonic characterizations by the use of geo-electrical resistivity technique and their implications on environmental soil and groundwater at Erbil dumpsite, west of Erbil city – Iraqi Kurdistan region
Authors: Gardi Sirwa Qader Smail , Asfahani Jamal
Published: November 2019

Twenty seven vertical electrical resistivity soundings (VES), distributed on three profiles, have been carried out around the Erbil city dumpsite location in northern Iraq, by using Schlumberger configuration. The main objective of those VES soundings is to characterize the subsurface structures and to detect the probable soil contamination zones at the dumpsite and the surrounding district. Bai Hassan aquifer in the study region is one of most important natural fresh water in the central sub-basin of Erbil. The 2D Pichgin and Habibulleav technique is applied herein to study and analyse the three VES profiles. Its application in the study region has highly demonstrated the efficacy of such a technique. In fact, the subsurface structures in the study area have been recognized, and the exact position, dip, direction of the faults and groundwater level were also precisely detected. The role of applying this technique together with the available geological information, while carrying out geo-electrical surveys is emphasized to obtain useful, cheap and fast lithological, groundwater table and structural subsurface information.
Deep gravity data interpretation using seismic reflection and well data: A case study of the West Gharib-Bakr area, Eastern Desert, Egypt
Authors: Azab Ahmad A.
Published: November 2019

A rigorous processing and analysis of the gravity data with seismic reflection and borehole information enabled a general view of the deep-seated regional structures in the West Gharib-Bakr area, Eastern Desert, Egypt. In this context, several interpretational techniques were applied to learn more about the supra-basement structures and intra-basement sources. The interpretation started with a review of the seismic data to clarify the structural elements on top of the Miocene strata, where a number of isochronous reflection maps were constructed and had migrated into depth maps. The Bouguer anomaly map was processed using Fast Fourier Transform filtering based on spectral analysis to separate the gravity anomalies into its components. Gravity stripping was also performed under the seismic isopachs and density controls. The gravity effect of each rock unit was calculated and progressively removed from the original data to obtain a new gravity map on top of the Pre-Miocene. To ensure more reliable results, further filtering and analytical processes were applied to the stripped map. The results of seismic analysis show simple structural configurations at the Miocene level, with a significant increase of evaporite thickness along the Gulf of Suez coast. In contrast, analysis of the stripped gravity map reveals a more intricate structure at the Pre-Miocene level, with increasing numbers/lengths of faults on the basement surface. Lineament analysis shows two major peaks trending N0–20°W and N50–70°E, produced by two main forces in NNW–SSE (compression) and ENE–WSW (tension) directions. The models confirmed a rough and ruptured basement surface, with no evidence of any magmatic intrusions penetrating the sediments. The basement relief map delineates five basins/sub-basins in the area which are separated from each other by ridges/saddles.
Washing soda induced alteration of the differential cell count, nonself surface adhesion efficacy and nuclear morphology of the polyphenotypic cells of a freshwater sponge of India
Authors: Mukherjee Soumalya , Ray Mitali , Ray Sajal
Published: November 2019

Washing soda has been identified as a precarious contaminant of the freshwater ponds and lakes, the natural habitat of Eunapius carteri. Treatment of sublethal concentrations of washing soda for 384 hours exhibited a significant decrease in the densities of blast like cells, small and large amoebocytes. The percentage occurrence of granular cells and archaeocytes yielded a marked increase against the experimental concentrations of washing soda. Washing soda mediated alterations in the differential cell densities of E. carteri indicative of a state of physiological stress and an undesirable shift in the cellular homeostasis of the organism distributed in polluted environment. Experimental exposure of washing soda yielded a significant increase in the cellular dimensions of large amoebocytes and archaeocytes. Prolonged treatment with washing soda presented a gross reduction in nonself surface adhesion efficacy of E. carteri cells. Experimental concentrations of washing soda resulted in a dose dependent increment in the frequencies of binucleation and micronucleation in the cells of E. carteri. The data were indicative of a high level of genotoxicity of washing soda in E. carteri. The present investigation provides an important information base in understanding the toxin induced chemical stress on the archaic immune defense of a primitive urmetazoa.
An attempt to increase technological capabilities of laboratory vibratory mills by changing the construction of chamber
Authors: Tomach Paweł
Published: November 2019

The paper presents the issues related to the grinding process in the vibration mills with low vibration frequency. These mills are rated among devices with high energy of impacts with much wider potential of industrial use than the classic gravitation mills. In vibratory mills there is an unfavorable decrease in the intensity of the grinding process along with the increase in the chamber diameter, which makes it impossible to achieve high performance of such devices. One of the ways to reduce or eliminate this occurrence is to intensify the load movement inside the chamber – this is the subject of this article. The article shows that in a vibrating mill of periodic action it is possible to increase its technological capabilities by application of an appropriate cylindrical component permanently installed inside the milling chamber. The paper also presents an attempt to increase the technological capabilities of a laboratory continuous vibratory mill.

Published: November 2019

The variety of accidents which happen during the construction of oil and gas wells causes the expansion in the use of magnetic fishing tools. However, the known tools based on permanent magnets have a significant drawback involving the flat working surface of the magnetic system that does not permit to achieve a considerable attraction force to a fished object of complex geometric shape. Therefore, the aim of the research is to increase the efficiency of removalthe objects of irregular geometric shape from the wells by enlarging the area of contacting them. For that purpose, it has been developed a fundamentally new design of the large-diameter fishing tool with the moving magnetic systems capable of copying the shape of the objects to be fished. Each magnetic system, which is compound of permanent rare-earth neodymium magnets and concentrically placed magnetic cores, shall be held by the magnetic field of adjacent systems with opposite polarity. There were conducted theoretical studies using the finite element method to determine the working capacity of the designed tool. As a result, it has been found the valueof hoisting capacity during the interaction of magnetic systems with the roller cone of the drill bit; this fact confirms the capability of fishing the objects of irregular geometric shape. In addition, it has been explored the influence of the material of the fished object on the power characteristics of magnetic systems. The application of the designed magnetic tool allowsremoving the ferromagnetic objects from the well regardless of their shape, weight and position onthe bottom hole. Apart from that, the given tool may be used in the areas where the technology of work is related to drilling wells.
The influence of belt cover thickness on conveyor belt indentation rolling resistance
Authors: Woźniak Dariusz
Published: November 2019

One of the methods for lowering of energy consumption in the drive mechanisms of long horizontal belt conveyors is to reduce belt indentation rolling resistances. These resistances depend on a number of factors: bottom cover properties, bottom cover thickness, belt design, idler diameter, load, speed and frequency at which the belt passes on the idler (indentation frequency), as well as on temperature. Determining how these factors influence indentation rolling resistances of various conveyor belt types is of great importance. The article describes a small-scale method for testing indentation rolling resistance. The method allows analysis of the influence of various factors on indentation rolling resistances. The article presents the results of tests on how belt indentation rolling resistance is influenced by thickness of the belt bottom cover. The tests were performed on belts with various core types.
Directions for increasing conical picks’ durability
Authors: Bołoz Łukasz
Published: November 2019

Conical picks are cutting tools used in many branches, in particular in the mining, road construction and building branch. Contact with the excavated face causes their constant wear, which is an unfavorable but unavoidable process. Milling heads of working machines are equipped with several dozen conical picks, and mining in abrasive or hardly accessible rocks can reduce their life to a few hours. It is in the interest of both users and producers to increase their durability, as tools replacement, apart from purchase and logistic costs, results in machine downtimes. In the article various solutions of conical picks, their construction, dimensions and materials used have been discussed. Technical procedures applied to increase the durability of conical picks and their regeneration as well as methods of extending the life of picks working in difficult conditions have been presented. Two author’s methods of extending the life of picks working in difficult conditions, covered by a patent application, have also been presented. The first solution involves ensuring an uninterrupted rotational movement of the pick in the holder. Patent claims include an innovative method of equipping the additional sleeve integrated with the holder with a rotational bearing, which enables a continuous rotation of the pick. The tool equipped with a bearing generates much lower movement resistance than the standard mounting. The holder is designed to mount classic commercial picks. What is important, the pick replacement does not require interfering with the bearing assembly. The second solution concerns the manner of protecting the working part of the pick by means of a special element made of an abrasion resisting material. This element is the pick tip, the geometry of which varies from the commonly applied posts made of sintered carbide. In this solution, the tip has a shape corresponding to the form of conical pick’s wear, which causes that its steel body does not wear. Moreover, there is a possibility of applying a mobile, rotational mounting of the tip to the body.
Modelling and simulation tests of a quadrocopter flying robot
Authors: Ciesielka Wojciech , Suchanek Grzegorz
Published: November 2019

In recent years, there has been a dynamic increase in the use of multirotor flying robots in various areas of economic and social life. Robots of this kind may be used in environmental research, after equipping them with an appropriate measuring systems. This includes taking measurements of various types of contaminants, such as: particulate matter (PM), various gases, noise and light pollution. To make this possible, it is necessary to conduct advanced model-simulation tests of the flying platform, analyse and determine the appropriate location for the measurement system. Most of the current research on methods and techniques of taking measurements on the flying platform does not take into account these issues. This work consists of two main parts: modeling and simulation tests, and experimental part carried out in laboratory conditions. As part of the work, quadrocopter dynamics equations have been developed and implemented in the Matlab/Simulink environment. The developed discrete mathematical model made it possible to simulate different robot maneuvers: upward, forward, sideways and rotation flight. In order to determine the required characteristics of the multicopter drive sets, a mobile dynamometer station was designed, constructed and programmed. The dynamometer allows, among others, to take measurements of thrust force, torque and rotational speed. The final stage of the work was the development of the numerical model and CFD calculations of the quadrocopter. In this part, distributions of the pressure fields and velocity for the robot's hover state were determined.
Modelling of global solar irradiance on sloped surfaces in climatic conditions of Kraków
Authors: Michalak Piotr
Published: November 2019

The paper presents calculations of global solar irradiance on inclined surfaces of any orientation in the hourly time step. For computational purposes there were used the data from typical meteorological years (TMY) available in a form of text files on the website of the Ministry of Infrastructure and Development. Hourly solar global horizontal irradiance from measurements from the file for Kraków was used as input for five anisotropic models (Hay, Muneer, Reindl, Perez and Perez according to the new PN-EN ISO 52010-1 standard). Direct normal and diffuse horizontal and then global irradiances were calculated. To illustrate the effects of using different models, for the exemplary residential building, monthly solar heat gains and heating demand was determined according to the monthly method of PN-EN ISO 13790. In comparison to the solar data from the TMY, an average decrease in the value of solar gains amounted 37%, what resulted in an increase in the calculated heat demand of the building by 10%. This is very important since this change takes place without any modernisation works.

Published: November 2019

Emotions influence individual behavior and there is no emotional experience that has a stronger influence than stress. Prolonged stress has a direct negative influence on physical and emotional conditions. For that reason, it is important to know a person's mental stress state, so that further action can be taken later, so as not to have a serious impact on physical and mental health. In this study, the photoplethysmograph (PPG) approach is used to recognize mental stress conditions based on Heart Rate Variability (HRV) frequency domain analysis. In this study stress was identified by SVM classifier using LF, HF and LF / HF Ratio from HRV frequency domain analysis. The LF results were increased in mild stress conditions, HF increased in conditions of mild stress and medium stress and the LF / HF Ratio slowly increased from mild stress to severe stress. The training data obtained 80 data with 95% mild stress accuracy from 19 data, medium stress accuracy 96% from 49 data and 99% severe stress accuracy with 12 data.

The extraordinary low non-radiative recombination and band gap versatility of halide perovskites have led to considerable development in optoelectronic devices. However, this versatility is limited by the stability of the perovskite phase, related to the relative size of the different cations and anions. The most emblematic case is that of formamidinium lead iodine (FAPI) black phase, which has the lowest band gap among all 3D lead halide perovskites, but quickly transforms into the non-perovskite yellow phase at room temperature. Efforts to optimize perovskite solar cells have largely focused on the stabilization of FAPI based perovskite structures, often introducing alternative anions and cations. However, these approaches commonly result in a blue-shift of the band gap, which limits the maximum photo-conversion efficiency. Here, we report the use of PbS colloidal quantum dots (QDs) as stabilizing agent for the FAPI perovskite black phase. The surface chemistry of PbS plays a pivotal role, by developing strong bonds with the black phase but weak ones with the yellow phase. As a result, stable FAPI black phase can be formed at temperatures as low as 85°C in just 10 minutes, setting a record of concomitantly fast and low temperature formation for FAPI, with important consequences for industrialization. FAPI thin films obtained through this procedure preserve the original low band gap of 1.5 eV, reach a record open circuit potential (Voc) of 1.105 V -91% of the maximum theoretical Voc- and preserve high efficiency for more than 700 hours. These findings reveal the potential of strategies exploiting the chemi-structural properties of external additives to relax the tolerance factor and optimize the optoelectronic performance of perovskite materials.

The ability to reproduce the experimental structure of water around the sodium and potassium ions is a key test of the quality of interaction potentials due to the central importance of these ions in a wide range of important phenomena. Here, we simulate the Na+ and K+ ions in bulk water using three density functional theory functionals: 1) The generalized gradient approximation (GGA) based dispersion corrected revised Perdew, Burke, and Ernzerhof functional (revPBE-D3) 2) The recently developed strongly constrained and appropriately normed (SCAN) functional 3) The random phase approximation (RPA) functional for potassium. We compare with experimental X-ray diffraction (XRD) and X-ray absorption fine structure (EXAFS) measurements to demonstrate that SCAN accurately reproduces key structural details of the hydra- tion structure around the sodium and potassium cations, whereas revPBE-D3 fails to do so. However, we show that SCAN provides a worse description of pure water in comparison with revPBE-D3. RPA also shows an improvement for K+, but slow convergence prevents rigorous comparison. Finally, we analyse cluster energetics to show SCAN and RPA have smaller fluctuations of the mean error of ion-water cluster binding energies compared with revPBE-D3.

El uso de las nuevas tecnologías en el tiempo libre es cada vez más frecuente entre la población adolescente. Este hábito puede tener como consecuencia una disminución de la actividad física diaria, generando así problemas de salud como el sobrepeso y la obesidad. Esta investigación pretende estudiar las horas diarias de pantalla durante el tiempo libre de 1.264 estudiantes de 1º y 4º de Educación Secundaria y comprobar si éstas se relacionan con la actividad física que practican; además se plantea conocer si existen diferencias significativas en las horas diarias de pantalla según el sexo y el curso escolar de los encuestados. Los resultados muestran que un 47.7% de los adolescentes encuestados pasan 5 horas o más al día ante la pantalla ya sea televisión, videojuegos o usando el ordenador; y además se trata de un hábito más frecuente en el alumnado de 4º de ESO. No se encontraron diferencias significativas según el sexo, en cambio sí las hay según el curso escolar pasando más tiempo ante la pantalla los alumnos de 4º de ESO que los alumnos de 1º de ESO. Por otro lado, la falta de relación entre las horas de pantalla y la práctica de actividad física confirma lo encontrado en otros estudios internacionales: ambas actividades son compatibles porque se producirían en distintos momentos del día.

Precision mechanical tillage is a fundamentally new agricultural strategy of farming, which is based on the use of information technology and new technical means and involves the implementation of technological measures for the main and pre-sowing tillage, taking into account the spatial heterogeneity of the physical properties of the root-content layer as indicators of differentiation of field tillage. In the article were presented the main provisions and stages of the method of determining the soil spatial heterogeneity of the plot. It was characterized indicators of precision mechanical soil tillage and promising methods for measuring parameters for precision tillage, including technical and software. It was proposed the preliminary norms of the physical properties of the treated layer for substantiation of the intensity of the basic mechanical soil tillage. It was proposed the characteristic of the main stages of the transition to precision farming and the mechanisms that should ensure its effective functioning, it was calculated the expected economic efficiency of precision farming. In the article was analyzed the spatial heterogeneity of arable land of Ukraine in terms of basic physical characteristics (structure, bulk density and penetration resistance) in the crop layer and plow sole. Some general patterns of manifestation of the spatial heterogeneity of the investigated properties of the soil cover of the land plots and the crop in all natural zones of Ukraine are analyzed, it serving as the main argument for the transition from generalized zonal technologies to precision mechanical tillage. The baseline data for the technological substantiation of the development of precision tillage (according to the content of the blocks in the seed layer) was worked out. Prospects for the introduction of precision agriculture in Ukraine are considered, based on the successful experience of mastering precision farming systems. Key words: soil, precision tillage, spatial heterogeneity, physical properties.

Published: November 2019

Object Oriented Software Development (OOSD) is a design technique that is used before the development and design of a software. This design method makes the system appears as a collection of objects to communicate with other objects by passing messages. The Model-View-Controller (MVC) has been inherited from Object-Oriented Programming (OOP) with the integration of Graphical User Interface (GUI) and interactive program execution. The MVC is very useful for developing Interactive and Dynamic Web Applications and iOS. With MVC, developers can trust on design patterns that are widely accepted as solutions for recurring problems. MVC can be used to develop flexible, reusable and modular Software. Applying the MVC design pattern in object-oriented Software development a flexible, reliable, modular and scalable website can be built. So, it’s necessary for every developer to have the knowledge of software development using MVC design pattern.
