One of the most promising areas of dental caries prophylaxis is remineralizing therapy aimed at normalizing the mineral composition of tooth enamel. As a result of a set of scientific, experimental and clinical studies, gels and drug films for the treatment of enamel caries have been developed.The aimof this work is to study remineralizing activity of dosage forms for the treatment of initial enamel caries.Materials and methods.As active pharmaceutical substances in dosage forms, calcium chloride (FS 42-0006-5675-04 P.003964.01), potassium phosphate disubstituted (FS 42-1297-79), sodium fluoride (PS.2.2.0013.15), auxiliary substances – gelling agent sodium-carboxymethylcellulose (sodium-CMC) C75 (TU 6-55-39-90), plasticizer glycerin (PS.2.2.0006.15), purified water (PS.2.2.0020.15) – have been used. Remineralizing activity was studied by the method of determination of calcium and phosphorus in the enamel ash in vitro. The study of remineralizing activity was carried out by the method of determination of calcium and phosphorus in the enamel ash in vitro. Quantitative determination of calcium was carried out by reverse complexometric titration, and the one of phosphorus was carried out by photoelectrocolorimetry. The electro-metric study of the enamel electrical conductivity was also carried out in vivo with the help of the Dentest device (Geosoft).Results and discussion. The method of determination of calcium and phosphorus in the enamel ash in vitro is based on tooth ashing and the subsequent determination of calcium and phosphorus in it by chemical and instrumental methods. Basing on the results obtained, it has been established that gel and drug films used for enamel caries treatment significantly increase the content of calcium and phosphorus in tooth enamel. The conducted electrometric study confirmed the increase in the hardness of the enamel structure due to its remineralization after the use of drug films.Conclusion. As a result of the studies conducted in vivo and in vitro, it has been established that the developed dosage forms have a remineralizing effect and can be recommended for increasing the effectiveness of prevention and treatment of the initial enamel caries.

Heart rate variability values are potentially important for assessing vegetative dysfunction in children.The purpose of the research: a comparative study of spectral heart rate variability parameters and synchronization of low-frequency oscillations, characterizing baroreflex in the vegetative regulation of the cardiovascular system in healthy newborns and adults.15 healthy newborns and 60 healthy individuals in the age of 18-34 years old were included in the study. We performed synchronous recording of electrocardiograms and photoplethysmograms with 10 minutes duration, at rest. Were evaluated spectral heart rate variability indices and the index of synchronization of low-frequency oscillations in heart rate variability and photoplethysmograms (S index).Results. In newborns, the peak of low-frequency oscillations was predominantly in the range 0.07–0.09 Hz, and high frequency 0.40–0.50 Hz. Newborns had lower LF% values than adults: 22.8 (14.1, 29.4) vs 32.9 (25.1, 41.9) (p=0.009). The S index in newborns was 20.1 (16.9, 26.5)%, and 33.2 (21.2, 45.4)% in healthy adults (p=0.023).Conclusion. We have first demonstrated that the interaction of baroreflex regulation of heart rhythm and peripheral blood filling in healthy newborns is characterized by lower values of S index, than in healthy adults, which can be explained by the immaturity of the vegetative regulatory elements of the cardiovascular system.

Tutkimuksessa selvitetään esikouluikäisten lasten suhdetta nykyajan verkottuneisiin älyleluihin. Olemme erityisen kiinnostuneita Lelujen Internetiin liittyvästä opetuksellisista arvoista, opetuksellisesta sisällöstä ja niillä tapahtuvasta leikistä, jonka kautta leikkivälineet on mahdollista nähdä osana suomalaisessa esikouluympäristössä tapahtuvaa varhaiskasvatusta.
Lelujen Internetin kanssa toimiessaan lasten on ajateltu oppivan eri asioita niin lelujen fyysisiä kuin etenkin niiden digitaalisia käyttömahdollisuuksia hyödyntäen. Tutkimuksemme selvittää yhtäältä, millaisia monimediaalisia leikin muotoja Lelujen Internetiin kytkeytyvät leluhahmot tukevat ja toisaalta, millaisia oppimisen mahdollisuuksia niihin sisältyy. Yksi tapaustutkimuksemme päätavoitteista on tarkastella, millaisia oppimislupauksia leluvalmistajat lelujen internetiin liittävät ja toisaalta, miten nämä lupaukset täyttyvät lasten käyttäessä leluhahmoja osana leikkiään. Tutkimukseemme sisältyy kolme osa-aluetta: leluvalmistajien antamat lupaukset lelujen opetuksellisista ominaisuuksista, esikouluikäisten lasten vanhempien ja opettajien asenteet teknologisia ominaisuuksia sisältäviä älyleluja kohtaan ja esikouluikäisten lasten oma näkemys näiden lelujen sisältämästä opetuksellisesta potentiaalista.
Lähestymistapamme on monitieteinen ja eri menetelmiin perustuva. Tutkimuksemme käsittää kolme eri aineistoa. Se sisältää Lelujen Internetiin lukemiemme hahmolelujen opetuksellisten ominaisuuksien kartoituksen lelunvalmistajien näkökulmasta, esikouluikäisten lasten vanhempien ja esikouluryhmän kahden opettajan lomaketutkimushaastattelut ja kahdenkymmenen esikouluikäisen lapsen kanssa tehdyt ryhmähaastattelut esikouluympäristössä suoritetuista lelutestaustilanteista. Tutkimuksessa kysymme, mihin opetustarpeisiin tarkastelemamme lelut vastaavat ja millä tavoin ne sopivat osaksi suomalaisessa esikouluopetuksessa käytettyä muodollisen mutta leikin kautta toteutuvan oppimisen ympäristöä. Tutkimuksemme osoittaa, miten lelut sopivat leikillisen oppimisen välineiksi, kun esikouluopettajat ottavat nämä leikkivälineet osaksi suunniteltua ja ohjattua opetusta.
European Normative Power During Ukrainian-Russian Conflict
Authors: Veebel Viljar , Markus Raul 
Published: September 2018

Abstract
During last two decades the European Union as “normative power Europe” has been associated with the export of certain universal norms, rules and practices to the other countries. Rule of law, democracy, strong commitment to human rights and fundamental freedoms, and social justice — these principles form the core of the identity of the European Union. Relying on shared political, economic and cultural ties among member states, the EU has sought to promote these norms also in the neighbouring countries, including Russia. However, the outbreak of the violent conflict between Russia and Ukraine at the end of 2013 clearly demonstrates that the EU has failed in its efforts in Russia despite extensive mutual relations and comprehensive financial support provided by the EU. The aim of the current article is to analyse how consistent the EU has been in defending and promoting European values and norms in the international arena and with Russia during the Ukrainian-Russian conflict.

Published: September 2018

Abstract
Malignant Peripheral Nerve Sheath Tumors (MPNSTs) are one of the very rare high grade malignancies usually affecting extremities or trunk. Incidence is 1/Lac. Intracranial MPNSTs are even rarer, schwannomatous and commonly affecting cranial nerves VIII &VII). Intra-cranial MPNSTs are usually sporadic, arising de novo. The second most common mode of origin is from malignant transformation from pre-existing schwannomas or neurofibroma. We present an extremely rare and probably the first case of intra-cranial malignant peripheral nerve sheath tumor of the olfactory nerve in a non neurofibrosis patient with no prior history of irradiation.

The algorithm of calculation of spatial coordinates of the car points and errors of their definition has been created and used for the research. In this case calculations of spatial provision of the point and its error have been reduced to definition and to the solution of the equations system of the second order in the MathCAD program environment. As the controlled and measured parameters at coordinates’ calculation of distances from laser measuring instruments to the studied car points were accepted.Results. As aresult, the mean square error of measurement of distance between control points significantly decreases at reduction of the passport error of laser range finders. At the size of the passport error of laser range finders equals 0,8 mm, the mean square error of measurement of distance between control points (from 0 to 3000 mm) equals 2,2-2,9 mm, and an error of definition of the control point is 1,5-1,9 mm.Discussion and conclusion. The conducted research demonstrates that it is necessary to compare the reached accuracy parameters at the set configuration of laser measuring system with the shown standard restrictions for an error of measurements. Therefore, further improvement of characteristics of accuracy of measuring systems is possible due to progressive decrease in an error of laser range finders as a result of their technical improvement.

Published: September 2018

Introduction. The actuality of the research is emphasized in the Strategy of proclaiming the desire for zero mortality on the country’s roads. Increasing the functional durability (the service life period) of horizontal road markings is an effective and cheap way to organize the movement of vehicles and pedestrians, which could reduce the number of accidents by 15-30%.Methods. The detailed factor analysis, influenced on the functional durability of the horizontal road markings and on the durability forecasting methods, is made by the authors.Results. The authors have established the main factors determining the functional durability of the horizontal road marking. They are divided into five groups: weather-climatic; mechanical; properties of the marking material; technological; properties of the road pavement. Moreover, the article presents a critical analysis of the existing methods of forecasting the functional durability of horizontal marking. In foreign publications on the issue under consideration there is no work on the prediction of the functional durability of horizontal marking by creating complex mathematical models. Most foreign and Russian models are based on empirical dependences. However, these methods and models do not take into account a number of important factors, such as the degree of roughness and abrasion of stone materials, their embedding in asphalt concrete coating, etc.Disscussion and conclusion. The authors came to the conclusion that attempts to create a single reliable mathematical model that takes into account more than 40 factors couldn’t be realistic. Therefore, there is a task of developing a number of models that allow to have greater extent that take into account the properties of the road surface, the location and variety of marking lines and predict the functional durability of horizontal road markings for different types of road pavement more reliably.

Introduction. Diffusion of aggressive components of the external environment deeper into the concrete intensively flows through the contact surfaces and between the filler and the cement matrix. Therefore, it is better to apply active fillers that interact with the cement matrix on certain mechanisms for reducing the conductivity of the contact surfaces, which leads to the products durability.Materials and methods. Methods of mechanical testing, x-ray phase analysis, scanning electron microscopy were used for comparative studies of concrete corrosion resistance with the active filler (urtite) and with the inactive one (quartz sand).Results. This research indicates that the urtite filler significantly increases the strength and corrosion resistance of concrete in comparison with the traditional filler with quartz sand. The investigation of the contact zone of cement stone-aggregate with the usage of REM demonstrates that there are no corrosion products in the contact zone of urtite with the cement matrix, while the contact zone of quartz sand and its surface acquires corrosion products represented mainly by gypsum.Discussion and conclusion. The increased corrosion resistance of the fine aggregate concrete through the application of active filler on the basis of urtite provides lower conductivity of the contact surfaces between cement matrix and filler due to the chemical affinity of the rock-forming minerals of nepheline to calcium hydroxide. The additional factor that enhances the self-inhibition of acid corrosion is the formation of the gel-like layer of silica on the surface of nepheline, which inhibits the advancement of hydroxide ions due to the flow of electro-surface processes. Thus, the nepilnameciais fillers are appropriate to apply in concrete, which is used in the conditions of the chemical aggression of high intensity.

Abstract
This work deals with “Full-Core” VVER-440 extended calculation benchmark which was proposed on the 24th Symposium of AER in October 2014 [2]. This benchmark is based on calculation benchmark defined by ŠKODA JS a.s. on the 21st Symposium of AER in 2011 [1]. This benchmark differs from the first “Full-Core” VVER-440 benchmark in use of control rods from group No. 6. Reason why these benchmarks exist is problematic validation of power distribution predicted by macro-code on the pin by pin level against experimental data. This new benchmark is also a 2D calculation benchmark based on the VVER-440 reactor core cold state geometry with taking into account the geometry of explicit radial reflector. Loading pattern for this core is very similar to the first pattern of the Mochovce NPP. This core is filled with fuel assemblies with enrichment of 1.6%w 235U, 2.4%w 235U and 4.25%w 235U. The main task of this benchmark is to test the pin by pin power distribution in fuel assemblies predicted by macro-codes that are used for neutron-physics calculations especially for VVER reactors. The reference solution has been calculated by MCNP6 code using Monte Carlo method and the results have been published in the AER community. The results of reference calculation were presented on the 27th Symposium of AER in 2017 [3]. In this paper is presented comparison of available macro-codes results for this calculation benchmark.
