Evidential Networks for Evaluating Predictive Reliability of Mechatronics Systems under Epistemic Uncertainties
Authors: Amrani Nabil B. , Saintis Laurent , Sarsri Driss , Barreau Mihaela
Published: August 2019

In reliability predicting field, the probabilistic approaches are based on data relating to the components which can be precisely known and validated by the return of experience REX, but in the case of complex systems with high-reliability precision such as mechatronic systems, uncertainties are inevitable and must be considered in order to predict with a degree of confidence the evaluated reliability. In this paper, firstly we present a brief review of the non-probabilistic approaches. Thereafter we present our methodology for assessing the reliability of the mechatronic system by taking into account the epistemic uncertainties (uncertainties in the reliability model and uncertainties in the reliability parameters) considered as a dynamic hybrid system and characterized by the existence of multi-domain interaction between its failed components. The key point in this study is to use an Evidential Network “EN” based on belief functions and the dynamic Bayesian network. Finally, an application is developed to illustrate the interest of the proposed methodology.

Published: August 2019

Al doped ZnO (AZO) thin films were prepared on silica substrates by sol-gel method. The films showed a hexagonal wurtzite structure with a preferred orientation along c-axis. Suitable Al doping dramatically improved the crystal quality compared to the undoped ZnO films. Dependent on the Al dopant concentration, the diffraction peak of (0 0 2) plane in XRD spectra showed at first right-shifting and then left-shifting, which was attributed to the change in defect concentration induced by the Al dopant. Photocatalytic properties of the AZO film were characterized by degradation of methyl orange (MO) under simulated solar light. The transmittance of the films was enhanced by the Al doping, and the maximum transmittance of 80 % in the visible region was observed in the sample with Al concentration of 1.5 at.% (mole fraction). The film with 1.5 at.% Al doping achieved also maximum photocatalytic activity of 68.6 % under solar light. The changes in the film parameters can be attributed to the variation in defect concentration induced by different Al doping content.

Non-Cartesian Frame Transformation-Based Control of a Three-Phase Power Converter During Unbalanced Voltage Dip – Part I: Transformation Principles
Authors: Iwański Grzegorz , Maciejewski Paweł , Łuszczyk Tomasz
Published: August 2019

One of the currently investigated problems in power electronics-based electrical energy conversion is proper operation of electronic converters during grid voltage imbalance and harmonics. In classic control methods, it introduces oscillations of variables, resulting in the necessity to improve control systems with signals filtration and usually by application of resonant terms as part of current controllers. The paper presents a new approach to grid-connected inverter control based on transformation to a non-Cartesian frame, the parameters of which are correlated with grid voltage asymmetry. The proposed method results in resignation from resonant terms used as controllers and their replacement with proportional–integral terms for which anti-wind-up structures are significantly simpler than for oscillatory terms. The paper presents new transformation principles, features and some simulation results showing the waveforms of signals transformed to the new non-Cartesian frame.
Non-Cartesian Frame Transformation-Based Control of a Three-Phase Power Converter During Unbalanced Voltage Dip – Part II: Simulation And Experiment
Authors: Iwański Grzegorz , Maciejewski Paweł , Łuszczyk Tomasz
Published: August 2019

The paper presents a control method for the three-phase power converter operating under unbalanced grid voltage conditions. The method uses a new transformation to the non-Cartesian frame, which makes the controlled current vector components balanced in this frame even if originally the three-phase current is referenced as unbalanced. Furthermore, Park’s transformation makes the controlled variables constant, which allows to apply proportional–integral terms as current controllers independent of the required control target. Several control targets known from literature have been analyzed with regard to the required new transformation parameters, and the transformation parameters for all targets have been found. Simulation results are shown to prove the theoretical analysis, and the experimental test results are presented as practical validation of the proposed use of the non-Cartesian frame in control.

Authors: Dobrzyńska Małgorzata , Przysławski Juliusz
Published: August 2019

Introduction. A balanced diet can help to prevent cardiovascular diseases. It particularly applies to the increased risk patients, including postmenopausal women with dyslipidaemia.

Aim. The aim of this study was to assess dietary habits, and consumption of selected nutrients which may have influence on the cardiovascular risk and determine nutritional knowledge in the group of women.

Material and methods. The study was conducted in 60 postmenopausal women with dyslipidaemia. The nutritional status was assessed on the basis of anthropometric measurements. The assessment of nutrition was evaluated using a 24-hour dietary recall during 4 days. Based on the authors’ questionnaire, dietary habits and the level of knowledge on the cardiovascular risk factors were assessed.

Results. The diet of the studied group of women was characterized by excessive supply of energy derived from fat and inappropriate supply of cholesterol, dietary fiber, sodium and vitamin D. Based on the assessed dietary habits, it was shown that the patients preferred foods with reduced fat content and mostly added salt for preparing their meals. Knowledge of factors affecting cardiovascular risk was insufficient.

Conclusions. Inadequate diet with insufficient nutritional knowledge in the studied group of women may significantly increase the risk of cardiovascular diseases in the future.

Authors: Goniewicz Mariusz , Misztal-Okońska Patrycja , Gorgol Adam
Published: August 2019

The profession of paramedic is a recent profession functioning in Poland since 1992. Over those 27 years the training, the role and responsibilities given to paramedics have undergone many changes. Initially, paramedics were trained in two-year colleges (post-secondary schools) and were not qualified to administer medical emergency treatment (medical rescue procedures) at the place of accidents. At present, they are educated at universities and are qualified to apply emergency medical treatment by themselves, inter alia to ensure the safe transport of the injured person in a life-threatening emergency, provide mental support to the injured, and carry out health education and promotion. Moreover, they are the core personnel of the State Medical Rescue System (PRM).

The goal of the study was to present the history of the establishment of paramedical profession and its current role and responsibilities in the PRM.

The aim of the present study was to examine, evaluate and compare the effects of administered dipeptidyl peptidase-4 (DPP4) inhibitors saxagliptin and sitagliptin on lipid status parameters and blood pressure in rats with streptozotocine induced diabetes mellitus type 2. Forty-eight Wistar albino rats were divided randomly into 4 groups: 1. group I: control healthy group; 2. group II: rats with diabetes mellitus type 2; 3. group III: rats with diabetes mellitus type 2+ treated with 0.6 mg/kg of sitagliptin; 4. group IV: rats with diabetes mellitus type 2 treated with 0.45 mg/kg of saxagliptin. The rats from experimental groups were fed with a high-fat diet for 4 weeks and after 6–8 h of starvation received one dose of streptozotocin (STZ) intraperitoneally (25 mg/kg body weight) to induce type 2 diabetes mellitus (T2DM). Animals with fasting glucose above 7 mmol/L and insulin over 6 mmol/L were included in the study as rats with T2DM. Upon completion of the experiments, the blood was collected from the anesthetized animals and serum triglyceride (TG), total cholesterol (TCH), high density lipoprotein (HDL), and low density lipoprotein (LDL) were measured using spectrophotometry and commercial kits. At the beginning of the study and the day before sacrificing animals, the blood pressure and heart rate were measured by a tail-cuff noninvasive method. DPP4 inhibitors, as glucagon-like peptide-1 (GLP-1) agonists, were associated with modest reductions in DBP, LDL-C, TCH, and TGL and significant improvement in HDL, SBP and HR.

New observations of Tin Mineralization Potential Vis-à-Vis Ore Petrographic, Alteration and Geochemistry in the Southeastern part of Bastar Craton, Central India
Authors: Singh Abhimanyu , Singh Vinod K.
Published: August 2019

The Tin mineralizations occur around the Katekalyan area, hosted in the acid magmatic rocks. The evolution differentiating granitic magma shows residual melt enrichment where end products intruded as pegmatites into the rocks. The different kind of pegmatite occur as simple unzoned, recrystallized (granitic pegmatite), and metasomatic greisenised and albitised pegmatites which emplaced within the pre-existing rocks of metabasic intrusive, granite (KG), granite gneiss (KGG). Sometimes it also found in metasediments as mineralised and non-mineralised characters along the fractures and foliation planes trending N-S, E-W and more frequently are observed NNW-SSE trends. Cassiterite is most important Tin-ore mineral and associated with pegmatites. Some cassiterite samples exhibit colourless to brown shades zoning which indicate multi stage growth. The cassiterite samples contain significant amounts of Sn, Nb, Ta with minor W.

The partial melting model shows that the variation 5 to 50% partial melting of bulk continental crust for KG as well as KGG rocks but bulk distribution coefficient for Sr (DSr) shows low i.e. <<10. The upper limit of partial melting of bulk crust estimates ~50 % for KG and KGG rocks are consistent with required rheological, critical melt percentage to leave the source region has decreased granite melt which were capable to mineralised tin ore elements. It is interesting to note that the SnF4 and SnCl4 probably not stable in presence of water under geologically reasonable conditions.

Authors: Afifah Putri Dwi , Setiawan Budhi
Published: August 2019

The research location is geologically located in Jambi Sub-basin composed by Peneta Formation (KJp), Airbenakat (Tma), and Muara Enim (Tmpm). Specifically this research focuses on the physical characteristics and geochemistry of Middle Miocene black shale from Airbenakat Formation. The purpose of this research is to determine whether the black shale of this formation has the potential as a source rock. The method of this research are field observation that includes the description of rock samples and geological mapping, and laboratory analysis including rock geochemical analysis. Three samples were taken from black and fine-grained shale. Total organic carbon (TOC) values of the three samples taken ranged from 0.38-0.42%, the weight of TOC indicates a potentially close enough to produce hydrocarbons. the pyrolysis results show that the S1 data gives a value below 0.5 HC/g and S2 gives a value below 2.5 HC/g, so it can be seen that the three rock samples that tested are not sufficient enough to produce hydrocarbons. Overall the sample has a S2/S3 ratio ranging from 0.09-0.23 and Tmax-HI data has values ranging from 8-19 mg HC/g TOC, so it can be seen that the ratio S2/S3 less than 1 and the value of the index hydrogen below 50 mg HC/g TOC, It can be concluded that the samples are derived from type IV kerogen. The maximum temperature (Tmax) of pyrolysis shows a value of less than 4350C, where the values range from 350-4280C. So, it can be interpreted that the three samples are immature source rocks because the catagenesis phase to produce hydrocarbons has not been achieved. The conclusions is the three samples of black shale tested indicate potential as immature source rock and has the close enough ability to produce hydrocarbons. The result of the analysis then comparable with the result analysis of Airbenakat Formation Black Shale in Palembang Sub-basin which has fair-well ability to produce hydrocarbons.

Published: August 2019

This research work focused on the use of direct current resistivity method to analyse data collected from refuse dumpsite at eastern bye pass Minna. The study area lies approximately on longitude 60 36’19.84”E to 6036’23.15”E and latitude 90 38’04.97”N to 9038’08.25”N, with a dimension of 100m x 100m within the basement complex of north central Nigeria. Vertical Electrical Sounding was carried out on the dumpsite with the aim of delineating the leachate contaminant plumes using resistivity method. Nine electrical resistivity profiles were measured on the site. Six transverse profiles were conducted on the dumpsite with thirty-six vertical electrical sounding (VES) point, three transverse profiles was also conducted on the control site which is 100 meters away from the dumpsite having nine vertical electrical sounding (VES) point and a dimension of 40m x 40m. The resistivity data obtained was analyzed using winresist software. The data obtained from the study area revealed three underlain layer they are the topsoil, fractured basement and fresh basement. The dumpsite was typified by A-types and H-types of curve and the control site was typified by H-type of curves. Iso–resistivity maps at various depths were observed, at the surface, 3m, 5m,7m, and 10m for the dumpsite and the control site. It can therefore be inferred from this study that the depth of contamination is 7 meter and aquifer found within this depth are most likely to be contaminated by leachate and water bearing formation beyond the depth of 7m is safe from contamination. The rate of contamination of the study area is approximately 1.0 meter per year.

Published: August 2019

The bathymetry mapping using underwater acoustic technology very important in Indonesia waters. Bathymetry is the result of measuring the height of the seabed so that the bathymetric map provides information about the seabed, where this information can provide benefits to several fields related to the seabed. In bathymetry mapping uses underwater acoustic technology where among them is using Single beam echosounder and MBES (Multibeam Echosounder System), and multibeam echosounder (MBES) is acoustic equipment that is intensively used frequently in basic waters mapping. The advantage of using underwater acoustic technology is the acquisition and processing of data in real time, high accuracy and precision (correction of the bathymetry data was carried out with reference to the 2008 International Hydrographic Organization (IHO), and cannot be a threat or damage to objects. Retrieval of bathymetry data must use parallel patterns, namely: patterns with perpendicular sounding directions and tend to be parallel to longitudinal lines or in accordance with parallel sounding patterns.
Strong Correlation and Charge Localization in Kohn-Sham Theories with Fractional Orbital Occupations: The Role of the Potential
Authors: Hellgren Maria , Gould Tim
Published: August 2019

We study static correlation and delocalisation errors and show that even methods with good energies can yield significant delocalization errors that affect the density, leading to large errors in predicting e.g. dipole moments. We illustrate this point by comparing existing state-of-art approaches with an accurate exchange correlation functional based on a generalised valence-bond ansatz, in which orbitals and fractional occupations are treated as variational parameters via an optimized effective potential (OEP). We show that the OEP exhibits step and peak features which, similar to the exact Kohn-Sham (KS) potential of DFT, are crucial to prevent charge delocalization. We further show that the step is missing in common approximations within reduced density matrix functional theory resulting in delocalization errors comparable to those found in DFT approximations. Finally, we explain the delocalization error as coming from an artificial mixing of the ground state with a charge-transfer excited state which is avoided if occupation numbers exhibit discontinuities.

Published: August 2019

Polymers that depolymerize back to monomers can be repeatedly chemically recycled, thereby reducing their environmental impact. Polyphthalaldehyde is a metastable polymer that is rapidly and quantitatively depolymerized due to its low ceiling temperature. However, the effect of substitution on the physical and chemical properties of polyphthalaldehyde derivatives has not been systematically studied. Herein, we investigate the cationic polymerization of seven distinct o‑phthalaldehyde derivatives and demonstrate that judicious choice of substituents results in materials with a wide range of ceiling temperatures (from < –60 to 106 °C) and decomposition temperatures (109–196 °C). We anticipate that these new polymers and their derivatives will enable researchers to access degradable materials with tunable thermal, physical, and chemical properties.
Implications of the Fractional Charge of Hydroxide at the Electrochemical Interface
Authors: Gauthier Joseph , Chen Leanne D. , Bajdich Michal , Chan Karen
Published: August 2019

Rational design of materials that efficiently convert electrical energy into chemical bonds will ultimately depend on a thorough understanding of the electrochemical inter- face at the atomic level. Towards this goal, the use of density functional theory (DFT) at the generalized gradient approximation (GGA) level has been applied widely in the past 15 years. In the calculation of electrochemical reaction energetics using GGA-DFT, it is frequently implicitly assumed that ions in the Helmholtz plane have unit charge. However, the ion charge is observed to be fractional near the interface through both a capacitor model and through Bader charge partitioning. In this work, we show that this spurious charge transfer can be effectively mitigated by continuum charging of the electrolyte. We then show that, similar to hydronium, the observed fractional charge of hydroxide is not due to a GGA level self-interaction error, as the partial charge is observed even when using hybrid level exchange-correlation functionals.
Two-Dimensional Infrared Spectroscopy From the Gas to Liquid Phase: Density Dependent J-Scrambling, Vibrational Relaxation, and the Onset of Liquid Character
Authors: Ng Pack Greg , Rotondaro Matthew , Shah Parth , Mandal Aritra , Erramilli Shyamsunder , Ziegler Lawrence
Published: August 2019

Ultrafast 2DIR spectra and pump-probe responses of the N2O n 3 asymmetric stretch in SF6 as a function of density from the gas to supercritical phase and liquid are reported. 2DIR spectra unequivocally reveal free rotor character at all densities studied in the gas and supercritical region. Analysis of the 2DIR spectra determines that J-scrambling or rotational relaxation in N2O is highly efficient, occurring in ~1.5 to ~2 collisions with SF6 at all non-liquid densities. In contrast, N2O n 3 vibrational energy relaxation requires ~15 collisions, and complete vibrational equilibrium occurs on the ~ns scale at all densities. An independent binary collision model is sufficient to describe these supercritical state point dynamics. The N2O n 3 in liquid SF6 2DIR spectrum shows no evidence of free rotor character or spectral diffusion. Using these 2DIR results, hindered rotor or liquid-like character is found in gas and all supercritical solutions for SF6 densities ³ r * = 0.3, and increases with SF6 density. 2DIR spectral analysis offers direct time domain evidence of critical slowing for SF6 solutions closest to the critical point density. Applications of 2DIR to other high density and supercritical solution dynamics and descriptions are discussed.

Published: August 2019

This study is aimed to investigate the nutritional composition, phytochemicals and
antioxidant activity of red and purple variety of Ipomoea batatas (sweet potato) peels and
Manihot esculenta (cassava) periderm and cortex layers. The proximate composition
(carbohydrate, protein, fat, moisture, ash and minerals) was determined using standard
methods while phytochemical contents (phenolic, flavonoid, anthocyanin and carotenoid)
and antioxidant activity [2,2-diphenylpicrylhydrazyl (DPPH), ferric reducing antioxidant
power (FRAP), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS)
assays] were determined spectrophotometrically. Proximate analysis showed that both I.
batatas and M. esculenta contained high carbohydrate content ranged from 75.07% to
87.04% but zero protein and low-fat contents (0.83-2.2%). For the mineral contents, I.
batatas contained higher potassium, sodium, iron and magnesium than M. esculenta.
However, calcium was found higher in M. esculenta as compared to I. batatas. For the
phytochemical study, total anthocyanin content showed the lowest value (0.43-3.08 µg c-3
-gE/g) for both tubers as compared to total phenolic (37.28-71.79 µg GAE/g), flavonoid
(4.98-16.50 µg RE/g) and carotenoid (14.54-46.66 µg BC/g) contents. For the antioxidant
study, both purple and red variety of I. batatas showed higher percentages of inhibition
using DPPH assay with 87.93% and 87.62%, respectively compared to M. esculenta.
Meanwhile, FRAP assay displayed lower values than ABTS assay for both tubers. In
conclusion, both tubers, I. batatas and M. esculenta have close values of nutritional
compositions. However, I. batatas showed higher mineral contents (potassium, iron,
magnesium and sodium) and antioxidant activity than M. esculenta. For the
phytochemical content, I. batatas contained higher total flavonoid and total anthocyanin
contents while M. esculenta contained higher total phenolic and carotenoid contents.
Hence, this study suggested that tuber’s by-products have great potential for use in
functional food as they are cheap and readily available as well as reducing waste disposal.

Показано, что в состав исследованных гидратов входят преимущественно метан и этан. В состав более 85 % образцов входит гидрат кубической структуры I с содержанием этана до 4.2 мол.%. В образцах, содержащих гидрат кубической структуры II, концентрация этана составляла 12—14 мол.%. Уточненные параметры элементарных ячеек природных гидратов хорошо соответствуют данным, полученным при исследованиях искусственно синтезированных гидратов. Обсуждаются возможные механизмы образования гидратов кубической структуры II. Кратко рассмотрены аргументы в пользу вероятного наличия рассеянных газовых гидратов в придонных слоях Байкальских осадков и возможности небольших вариаций в составе гидратного газа в различных фрагментах гидратов, отобранных из одного и того же гидратного слоя.

In September 2017, a cluster of monophasic Salmonella Typhimurium isolates was identified at the National Reference Laboratory for Enteropathogenic Bacteria in Norway. We investigated the cluster to identify the source and implement control measures. We defined a case as a person with laboratory-confirmed salmonellosis with the outbreak strain multiple locus variable-number tandem repeat analysis type. We conducted descriptive epidemiological and environmental investigations and performed whole genome sequencing (WGS) with core and accessory genome multilocus sequence typing of all isolates from cases or the environment connected with this outbreak. We identified 21 cases, residing in 10 geographically dispersed counties, all of whom had consumed food or drinks from a café at Oslo Airport. Case distribution by date of symptom onset suggested that a point source was introduced in mid-August followed by continued environmental contamination. The incubation periods ranged 0–16 days and increased as the outbreak progressed, likely due to increasingly low-dose exposure as control measures were implemented. WGS confirmed an identical cluster type-944 in all cases and six environmental specimens from the café. Control measures, including temporary closure and kitchen refurbishment, failed to eliminate the environmental source. We recommend strengthened hygiene measures for established environmental contamination during an outbreak.
INSIGHTS INTO LINGUISTIC RESEARCH OF PERSPECTIVE IN DRAMA: THE CASE OF O. WILDE’S PLAYS
Authors: Tsys Yu.
Published: August 2019

The article focuses on linguostylistic means of representation of perspective in O. Wilde’s plays. The main feature of drama that limits the ways of expression of perspective is absence of the narrator. Thus, in the text of drama perspective can be represented through such narrative elements as prologue, author’s remarks, chorus odes, lines of epic characters and built-in narratives. These narrative elements can implement author’s perspective. The linguostylistic analysis of perspective in O. Wilde comedies lend support to the idea that the main stylistic means of expressing the author’s direct perspective are simile and epithet. The author’s indirect perspective can be interpreted from the lines of characters, it is usually represented in the text by means of irony and sarcasm. Character’s perspective can be interpreted from monologues, dialogues and polylogues and is predominantly verbalised through metaphor and epithet.
Naturalistic philosophy in Edith Wharton’s “The House of Mirth”
Authors: Білинська Х. В.
Published: August 2019

The article is dedicated to the issue of naturalistic philosophy in Edith Wharton’s “The House of Mirth”. The influence of heredity and environment on the protagonists’ development and behaviour has been stated. Edith Wharton emphasizes the heredity of two characters — Lily Bart and Lawrence Selden. She portrays how the qualities inherited from the parents and further intensified by upbringing affect their future welfare. The protagonists are under total control of their environment — the New York leisure-class society. It determines their motives and actions, as well as has overwhelming effect on their personal lives, ensured by means of gossip and public censure.

Edith Wharton has been proved to use repetition of the same actions and habits in order to achieve the effect of stuckness in one place. Incessant social events of the American elite, held in accordance with a strict protocol, lead to thingification of people. The society itself turns into a fetish. As a result, the typical naturalistic notions of “life as suffering” and “life as a prison” are achieved.

After a thorough investigation, it has been summarized that Edith Wharton’s “The House of Mirth” should be considered as a representative of the optimistic and idealistic stream of American naturalism.
Characteristics of the paradigm of the category of voice in the Old Saxon language
Authors: Шапочкіна О. В. ,   Borys Grinchenko Kyiv University
Published: August 2019

The article attempts to characterize the paradigm of the category of the voice of the Old Saxon language, based on the texts of the ancient saxon poem “The Savior” (“Heliand”). The author states that the category of the voice of the Old Saxon language was represented by pre-categorical inverse constructions with reflexive, reciprocal and inverse shades and participle passive constructions, namely copulative structures “to be / become” + II participle and non-copulative participle structures that broadcast different types of voice relations. It is proved that the active voice of the Old Saxon language was represented by the indicative (real voice), with the subject that was an active performer of the action. In particular, the active voice structures could be factual (agential). As in other Old Germanic languages, in the Old Saxon language the active voice expresses the reality of action, events, their prediction and shades of command. In particular, it is determined in the article that as an opposition of active voice were grammatical constructions that had shades of reversion (inverse, reciprocal, inverse), the so-called “branching” in shades of voice values: the actual inverse constructions, mutually reverse, indirectly reverse, ingressive, active-nonobjective. Shades of passivity were formed predominantly on the basis of pre-categorical constructions with the verbs “to be” / “to become” + participle II. In particular, in the corps of the ancient Saxon “Savior” there were a large number of non-copulative (free) structures with participle II, which could express passive or partiallypassive value. The author also notes that in addition to the typological distribution of the category of voice in the context of the opposition, “active-passive-reflexive”, in the Old Saxon paradigm of the category of voice there were observed subjective-objective relations, which in their turn had varieties: transformative, creative, addressive, factual, perceptual, emotional, instrumental.
Printed advertising of the end of the 19th — the first half of the 20th centuries in the context of a search of a source basis for a detailed description of the Ukrainian urban koine of this period
Authors: Закутня А. Ю.
Published: August 2019

The city as a peculiar form of social organization is interesting for the representatives of many trends of scientific research: economists, sociologists, culturologists, historians, linguists. The subject of our interest is the functioning of the Ukrainian language in the cities of Bukovyna and Galicia at the end of the 19th century — the first half of the 20th century, in the urban environment of the Ukrainian diaspora settlement.

Historical and socio-political conditions of the formation of the Ukrainian city koinй as one of the preconditions for the development of Ukrainian literature (particularly in the territory of Western Ukraine) — are still one of largely unexplored problems of Ukrainian linguistics — in both theoretical and practical aspects, which predetermines the relevance of the topic of our study. The aim of this article is the analysis of Ukrainian advertising texts at the end of the 19th century — the first half of the 20th century and identification of such lexical and syntagmatic units that can be classified as elements of the city koine.

To perform linguistic analysis we have involved over 80 language units (words, nominative word combinations, word variants) used for the nomination of over 30 items of commodity circulation belonging to the following lexical-semantic groups: names of clothing, footwear and other details of the wardrobe; names of household items of urban dwellers (personal use items). For every word of the aforementioned lexical-semantic groups we have provided illustrating contexts, commentaries concerning the meaning, use, origin, their record in different kinds of dictionaries, sometimes giving information from Polish lexicography, Polish and German electronic corpora.

We have analyzed the names of urban life items, documented in the Ukrainian advertisement at the end of the 19thcentury — the first half of the 20th century, that certify that the majority of such names are borrowings adapted on the Ukrainian language background: from German, Polish, French, Italian, Spanish, etc. Mainly Polish and German played an intermediary role in the assimilation of these words. We believe that lexical units and nominative word combinations recorded in the advertising texts of the 19th century — the first half of the 20thcentury, may serve as a basis for the register of lexicographic works of a specialized type, for instance, the Dictionary of Ukrainian Advertisement; the Dictionary of Western Ukrainian Variants of Literary Language of the 19th century — the first half of the 20th century, etc.

Authors: Рябова К. О.
Published: August 2019

The popularity of a hashtag is rising up every day. We use the hashtags to mark our messages or to find the information in the Internet. The hashtag has attracted attention not only Internet users but also scientists. The article focuses on the theoretical background and the approaches to the research of the hashtag as a kind of microtext. The author provides theoretical information about text and microtext, their main characteristics and classification as well as outlines the main linguistic features of the hashtag in the social networks Twitter, Facebook and Instagram. We have considered the etymology of “hashtag” and analyzed the previous works. The article presents the characteristic differences of microtext on phonetic-grapheme, lexical, syntactic levels. It is highlighted variation of pronunciation, graphic and phonetic substitutions, and spelling mistakes.

The paper investigates various aspects of using microtext in the social networks.

Despite the growing tendency to create playful corners on the part of the MIES and the MINEDUC, in the CDI there continues to be an urgent need for change in the actions of the educators, with respect to how the subject of sensory activities is being handled in the stimulation of children in their first years of life and thus implement meaningful learning, the problem focuses on the lack of sensory playful corners in perceptual stimulation The study was applied to 20 educators of 5 care units of the modality Child Development Center (CDI) of several rural sectors of the Portoviejo canton, having as objective to determine the use of sensory playful corners in the stimulation of children from 1 to 3 years. The results of this work showed that there are no sensory playful corners and that educators lack knowledge about the importance of creating these spaces and making them available to children for their learning, reaching the conclusion that there is a need to create an innovative guide with content sessions, skills, play materials for the corners of visual, auditory, gustatory, olfactory and tactile perception.
Kalça gelişimsel çıkığı'nın kapalı veya açık redüksiyon ile tedavisi sonrası Koksa Magna: Süreç veya sekel mi?
Authors: ASLAN Ahmet
Published: August 2019

Amaç: Bu çalışmada kapalı redüksiyon (KR)
ya da açık redüksiyon (AR) ile tedavi edilen tek taraflı Gelişimsel Kalça
Displazisi (GKD) olgularının takiplerinde görülen, Koksa Magna (KM) sıklığının
belirlenmesi ve etkileyen faktörlerin araştırılması amaçlandı. Yöntem: Hastalar retrospektif olarak iki gruba
ayrıldı. Grup 1: Genel anestezi altında kapalı redüksiyon (KR) ve PPA yapılan olgulardan
oluşuyordu. Grup 2: Medial yaklaşımla açık redüksiyon (AR) ve PPA uygulanan olgulardan  oluşuyordu. Son kontrolde femur başı çaplarının
ölçümü yapıldı. KM tanısına sağlam tarafa göre %15 daha  fazla büyüklük ölçütüyle karar verildi. Avasküler
nekroz (AVN) tanısı  Salter ve ark. ölçütlerine
göre kondu. AVN sınıflandırması Kalamchi-Mc Ewen  ölçütleriyle yapıldı.Bulgular: Gruplar arasında ameliyat öncesi Tönnis evresi ve tedavi yaşı bakımından
anlamlı farklılık vardı (sırasıyla p=0,000 ve p=0,003) ancak diğer parametreler
bakımından farklılık bulunamadı (p>0,05). Grup 2’de KM görülme sıklığı anlamlı
olarak daha fazlaydı (p=0,017) ancak AVN bakımından gruplar arasında fark
bulunamadı (p=0,532).

Sonuç: Bu çalışmanın ana sonuçları GKD
nedeniyle AR yapılan olgularda KM sıklığının daha fazla olduğunu
göstermektedir. KM iliopsoas tenotomisiyle ve/veya uygulanan tedaviyle ilişkili
patolojik olmayan bir durum olabilir. Bununla birlikte bu KM olguları Tip 1 AVN’un bir tezahürü
de olabilir. Bu konuda daha fazla olgu sayısıyla, sonuçları
etkileyebilecek faktörlerin en aza indirildiği, 
ileriye dönük iyi dizayn edilmiş çalışmalara ihtiyaç vardır.
