Primary Repair of Cleft Lip and Nose in the Neonatal Period
Authors: Valentova Strenacikova S , Malina R
Published: August 2018

Facial cleft malformations belong to the most common problems of the congenital facial anomalies. At the Clinic of Plastic, Aestetic and Reconstructive Surgery at the Faculty Hospital in Banská Bystrica we have been performing primary cleft lip repairs during the first week of life of a newborn since 1995. During this life period the fetal healing still persists. Modern anesthetic techniques have considerably reduced respiratory complications after the lip closure. The adequate postoperative sedation together with monitoring of the pacient remarkably reduces the occurrence of wound dehiscence. The advantages of the neonatal cleft lip repair are the scarless healing, no negative effect on the growth of the middle thirt of the face, as well as the pschychosocial effect on the family and the fact that the ortodontic aparat has not been needed.
Commemoration of Kárpáti Gizella, the first woman who took her degree in medical science in Kolozsvár at Ferenc József University
Authors: Mária Péter H.
Published: August 2018

On 31st of December 1895 Gyula Wlassics (1852-1937), minister of religion and education, published his Decree No 72 039, which allowed women to study medical science, pharmacy and humanities at universities. In Kolozsvár Gizella Kárpáti was the first woman who registered at the Faculty of Medicine of Ferenc József University.

Gizella Kárpáti was born in Kolozsvár on 3rd August 1884. After finishing secondary school in June 1902, in the autumn of the same year she registered at the Faculty of Medicine. The marks she got at the university examinations in the following 10 semesters proved that she could cope with her task. In the years spent at the university she met medical student József Szabó (born in 1882) whom she married later. They both started their medical career at Károly Lechner’s Neuro-Psychiatry Institute. From 1909 Gizella Kárpáti was a payed assistant, from 1911 she became assistant lecturer. Her husband became an assistant lecturer from the year 1908, then he was appointed lecturer and then honorary lecturer. Meanwhile he had to go to the front where he was followed by his wife. In 1919, after the professors of the university refused the act of swearing the oath of allegiance, they both made their escape from Kolozsvár together with the greater part of their fellow professors. After a short time they settled in Szeged, where József Szabó was appointed university professor. Here he published his book „Elmekórtan” in 1925. In the 1927-28 academic year he became dean, then vice-dean of the Faculty of Medicine, but in the year 1929 he died unexpectedly. In Szeged, Gizella Kárpáti being engaged in bringing up her two children, did not work as a physician. One of her children, Miklós, continued his parents’ profession, and became a physician. Gizella and her children returned to Kolozsvár for a short time, between 1940-1944, then they moved to Budapest and finally they settled in Szeged again. In 1929 József Szabó and in 1953 Gizella Kárpáti were entombed in one of the graves of honour of the Szeged central cemetery.

Accumulation of selected heavy metals in soils and common dandelion (Taraxacum officinale) near a road with high traffic intensity
Authors: Kajka Katarzyna , Rutkowska Beata
Published: August 2018

The aim of the study was to determine the levels of selected trace elements in soils and in the common dandelion depending on the distance from a traffic route. The study was conducted in Warsaw near one of the main roads in the suburb of Ursynów. Samples for testing were taken from the 0–25 cm layer at sites located directly alongside the roadway and at a distance of 30, 60 and 300 m from its edge. The amounts of Pb, Ni, Cu, Zn and Cd in the soils were determined by the AAS method, after extraction in HCl at a concentration of 1 mol·dm−3, and in the aboveground parts and roots of dandelion plants after wet mineralization in a mixture of HNO3 and HClO4 by the AAS method. On the basis of the results obtained, it was shown that the concentrations of the tested metals, both in the soils and in the biomass of the test plant, were highest directly at the edge of the roadway and decreased significantly with the distance away from the road. This correlation indicates a significant impact of road transport on heavy metal levels in the environment bordering a traffic route. It was also shown that dandelion plants accumulate higher amounts of heavy metals in the aboveground parts than in the roots, and the heavy metal contents in the dandelion biomass were found to be significantly positively correlated with the amounts of these elements in the soils.
Effect of variable content of organic matter and carbonates on results of determination of granulometric composition by means of Casagrande’s areometric method in modification by Prószyński
Authors: Warzyński Hubert , Sosnowska Agnieszka , Harasimiuk Andrzej
Published: August 2018

The paper discusses the issue of the admixtures’ effect on results of granulometric composition determinations by Casagrande’s areometric method in modification by Prószyński. An experiment was conducted involving preparation of samples with known granulometric composition and determination of their composition by means of the aerometric method. Three types of samples were prepared: base (control), containing organic matter, and containing carbonates. Results of the determinations showed a considerable effect of the admixture of organic matter and calcium carbonate on the accordance of determinations, depending on their percent content. The study results also confirmed known dependencies of disturbances in proportions between the sandy and silty-clayey fraction. A practical conclusion from the research is the determination of the threshold of the organic matter and carbonates percent content at which the determination should be absolutely preceded by processes of mineralisation and decalcification.

Authors: Mahdi Farouk M. , Eaqoob Jawadat A. , Muhialdeen Fouad R.
Published: August 2018

Copper -graphite composites are widely used in a great number of engineering applications such as brushes, switches, sliding bearings, self-lubricating bearings, etc. due to their good thermal and electrical conductivity and excellent tribological properties as compared with other structural materials. There are ongoing attempts in manufacturing copper composites with better properties to enhance their efficiency and increase their effective life. Present research aims to prepare hybrid 95wt.% copper –5wt.% graphite composites reinforced with yttria and tin particles by powder metallurgy technique and to study their effects on mechanical and physical properties of the prepared composites. Powder mixture was mixed by ball mill mixer at 100rpm for 120min with (5/1) balls to powder ratio. The powder mixture was cold pressed at 700MPa for 30sec, followed by sintering at 900 ˚C for one hour. In the first stage, Yttria(Y2O3) was added with (2, 4, 6, 8, 10) wt% to pure copper (Cu) and to (95%Cu-5%Gr) matrices. Typical composite of this stage was ((95%Cu-5%Gr)-4%Y2O3. In the second stage, tin (Sn) was added with (2, 4, 6, 8, 10) wt% to pure copper and((95%Cu-5%Gr)-4%Y2O3 matrices. Typical composite of this stage was ((95%Cu-5%Gr)-4%Y2O3)-6%Sn. The results showed that hardness and true porosity of the composites increases with increasing yttria content. On the other hand, both thermal and electrical conductivity of the composites decreases with increasing yttria content. It was also found that (95 wt.% Cu- 5 wt.% Gr) – Y2O3 composites have always lower wear rate than plain Cu-Y2O3 composites.

Position Control of Solar Panel Receiver by Joint Generated Power and Received Signal Power Maximization
Authors: Mohammed Bassam Fadel
Published: August 2018

The use of solar cells as photodetectors in Optical Wireless Communications (OWC) systems, is acquiring an increasing attention. This is due to the fact that a solar cell can detect an incident optical signal without the need to be biased by an external dc source, unlike traditional photodetectors. Basically, solar cells are designed to be used in solar energy harvesting systems. However, the solar cells are used during the day time and they remain idle at night. Then, they can be used in other applications, such as optical signal detection during night hours. Moreover, the efficiency of solar systems and solar receivers can be maximized by using dual axis light source tracking, to keep the cell orientation at the direction that results in the maximum electrical output. Therefore, in this paper, a solar cell positioning algorithm is proposed to track the maximum power point of both of the sun at day time and the optical communication signal at night. The proposed system can automatically distinguish between its two operation modes and then provides the necessary control. The proposed system is implemented and tested under realistic outdoor environment. It showed an accurate detection of the operation situation and also an accurate and smooth positioning during the specific operation mode. The measurement of the generated and consumed power by the designed system has emphasized it feasibility.

La Revolución Educativa, una re–organización… ¿educativa?
Authors: Velásquez Palacios Martha
Published: August 2018

Las interacciones e interrelaciones entre agencias, agentes y discursos del campo educativo nacional obedecen tanto a condiciones particulares de su dinámica como a tendencias de carácter internacional, de allí que para analizar las tendencias educativas nacionales resulte necesario hacer referencia a las internacionales e incluso a tendencias no educativas. Las políticas públicas, en el país, y particularmente las de educación no son ajenas a esto, ellas están inmersas en esas pujas y pugnas propias de un campo. Para analizar la educación en el país y la reorganización educativa propuesta desde la perspectiva oficial en la política pública de la Revolución Educativa, entender la construcción de las nociones que circulan resulta fundamental; dentro de ese proceso, el análisis de la recontextualización de noción de “educación” se propone dentro de esta investigación como primera etapa. Si el asunto del que se habla es la educación, empecemos por ver desde dónde se

habla de el.

Published: August 2018

Ultrasonic echo-pulse method is used to study the texture changes and Poisson’s coefficients of 15YuTA construction steel upon fatigue failure in the range of high-cycle fatigue. To describe the texture change, pole figures were constructed using the values of the orientation distribution functions (W400 and W420) obtained from the results of precise measurements of the propagation time of elastic bulk waves in sheet materials. The intensity ratio in the center of the pole figure and the point remote from the center of the pole figure by 45° along the rolling direction was used as a parameter characterizing the texture sharpness. It is shown that change in the texture sharpness is attributed to the development of microplastic strain and accumulation of the microdamages. A nonmonotonic dependence of the change in the texture sharpness on the number of loading cycles is observed. At the initial stage of loading, there is some increase in the sharpness of the texture, which can be attributed to the development of micro-strains on the most favorably oriented sliding planes. At the second stage, a decrease in the texture sharpness is associated with the scattering of the texture as the density of microdefects increases during the destruction of the alloy. The parameter characterizing the texture sharpness can be used as a pre-destruction indicator when monitoring the material of the structure by the ultrasonic method.

Published: August 2018

The publication activity of the leading countries in the field of quantum technologies (QT), which include quantum computers and simulators, quantum sensors, quantum data transmission, and quantum metrology is analyzed. A general characteristic of the subject domain and scientometric analysis is carried out using the research chops from the Web of Science database covering the period 2000 – 2016. The sample of bibliographic publications is used to (i) estimate the growth rate of publications on QT in the leading countries (for the indicated period of time), (ii) identify the leading states in the number of publications (on the above-mentioned main directions of QT development), and (iii) determine the publication activity of Russia and the intensity of international cooperation. The results of the research demonstrated, that the USA and China are the leading countries in the field of quantum technologies. Regression dependences are constructed which provide forecasting and description of the functions reflecting the increasing number of publications in aforementioned countries. Using the criterion of signs and the Wilcoxon test for coupled pairs of observations, the hypothesis of significant differences in the publication activity of the United States and China was tested. Both tests at the level of significance α = 0.05 did not reveal significant discrepancies between the number of articles in the US and China on the twelve topics of the Web of Science database. At the same time, a significant advantage of American scientists in the number of publications in the field of quantum computations and creation of a universal quantum computer has been revealed. The primacy in this area is the main condition of «quantum» domination, which implies a significant acceleration of calculations, primarily, decryption of most of the algorithms used to protect information.
The impact of different types of wave action on the destruction of stable gel-containing water-oil emulsions
Authors: Romanova Yu. N. , Musina N. S. , Maryutina T. A.
Published: August 2018

An original method of wave sample preparation of commercial stable gel-containing water-oil emulsions is developed to separate water and oil phases present in the composition for their subsequent analysis. Real samples of commercial stable water-oil emulsions, differing in composition (water content, «gel», iron sulphide and mechanical impurities) are studied. The effect of the intensity and duration of the wave action of different nature on the completeness of phase separation in the real samples of commercial emulsions of different composition are studied. A possibility in principal of isolating oil and water phases from the composition of stable water-oil emulsions stabilized by gel-like associates under wave action (magnetostatic and electromagnetic field, ultrasonic vibrations) is shown. When the water-oil emulsion is exposed to a permanent magnetic field with an induction range of 0.1 – 0.57 T for 1 – 3 minutes, the degree of water isolation from the emulsion samples under study varies from 48 % to 71 %, depending on the composition of the emulsion under study. Similar results are obtained under the effect of electromagnetic field with an induction of 0.1 – 1.0 T. For complete separation of water and oil phases from gel-containing water-oil emulsions, we proposed to use ultrasonic treatment combined with addition of a suspension prepared from aluminum oxide nanopowder in acetonitrile which provide complete destruction of «gel» and 100 % separation of water and oil phases.

Published: August 2018

Within InnoWEE project (Innovative pre-fabricated components including different waste construction materials reducing building energy and minimising environmental impact) construction and demolition waste (CDW) were processed into fine fractions which were further embedded into innovative high performance prefabricated geopolymeric panels. CDW fractions consisted of bricks, concrete, mortars, and wood chips. As a binder slag and metakaolin were used and activated by mixture of K/Na-silicate and KOH/NaOH. Optimized compositions were defined and panels were produced into sizes of 50 cm x 50 cm with the intended use for contact bonded (ETICs like) or ventilated façades. One type of panels was produced by using mainly inorganic CDW and are designated as high density geopolymer panels (HDP), another type was made of at least 40 % of CDW woodchips and designated as wood- based geopolymer panels (WGP). Panels were assessed for their durability according to the provisions of ETAG 004 and other relevant standards for façade systems; among them freeze – thaw resistance, impact resistance, water vapour permeability, capillary water uptake. Results showed that the performance of such panels is suitable for inteded use. “This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 723916”.
Energy-aware Task Scheduling Strategies for Multi-core Embeddded Systems
Authors: Zou Chengming , Panwen Liu , Liu Xing
Published: August 2018

In this paper, we propose two energy-aware scheduling algorithms---(1) Reinforcement learning-based multiprocessor scheduling (RL) algorithm and (2) Mathematical morphology multiprocessor scheduling (MMS) algorithm---for scheduling time-constrained Directed Acyclic Graph (DAG) tasks in an embedded multiprocessor system with Dynamic Voltage And Frequency Scaling (DVFS) and Dynamic Power Management (DPM) technology. Unlike other heuristic scheduling algorithms, the proposed reinforcement learning (RL) is a machine learning algorithm, rarely considered for energy-aware scheduling in DAG tasks. The MMS, inspired by Mathematical morphology that is often used in image processing, continuously adjusts the coded scheduling through a probe matrix to optimize energy consumption. In this paper the genetic algorithm (GA) is compared with these two proposed algorithms by rigorous simulation. The results demonstrate that our algorithms are more energy efficient. Compared with the GA algorithm, the RL and the MMS algorithm significantly improve the energy consumption reduction rate by an average of 13.37% and 72.92% respectively. In addition, MMS algorithm shows better performance in high-density and high-complexity DAG tasks.
