Authors: Mohammed Azeezaa Varsha , Sagadevan Suresh 
Published: August 2019

Abstract
L-cysteine hydrogen fluoride (LCHF) single crystals were grown from aqueous solution. Single crystal X-ray diffraction, FT-IR, UV-Vis-NIR, and TG-DTA were used to test the grown crystals. The specimen dielectric and mechanical behaviors were also studied. Powder X-ray diffraction of the grown crystal was recorded and indexed. The optical properties of the LCHF crystal were determined using UV-Vis spectroscopy. It was found that the optical band gap of LCHF was 4.8 eV. The crystal functional groups were identified using FT-IR. Second harmonic generation (SHG) efficiency of the LCHF was three times higher than that of KDP. The dielectric constant, dielectric loss and AC conductivity were measured at different frequencies and temperatures.

Abstract
Advances in nanotechnology in various fields of human activity contribute to increase of their production, improved properties and wider implementation of nanomaterials. However, increasing use may enhance their release into the environment and can lead to affecting human health. The toxicity of colloidal solutions of metal nanoparticles (Cu, Mn) and their oxides, obtained in the absence and presence of a stabilizer, was examined and compared with the use of the standard test system of Allium cepa L.. The phytotoxicity of the experimental solutions was evaluated according to the growth response of the onion roots; the cyto- and genotoxicity were estimated due to the proliferative activity of the root meristem cells. It was established that solutions of stabilized metal nanoparticles were at given concentration toxic to Allium cepa L. according to the integral index of roots growth, however, were not cytotoxic. Difference in the phytotoxicity of stabilized and non-stabilized metal nanoparticles and their oxides depended on their phase composition and affected root growth.

Abstract
Sulphur-oxidising autotrophic bacterial communities in deep biosphere from weathered ore samples from active gold mine Hodruša-Hámre, Slovakia were analysed using cultivation approach followed by DNA extraction, PCR amplification and 16S rRNA gene analyses. Indirect measurement of pH changes in cultivation media evidenced the presence of acidophilic bacteria with active production of acids. The decrease of pH was observed at the beginning of isolation and later pH in range of 1.5 – 2 was maintained in both, sulphuric acid and thiosulphate, media. The presence of homogenous population of gram-negative rods was proved by Gram staining. Molecular analyses have revealed that the population of sulphur-oxidising bacteria in gold mine is dominated by a single species of Aciditiobacillus genus, identified as A. albertensis, suggesting the low level of autotrophic bacteria diversity in deep deposits. For the first time this species was isolated from weathered rocks of a gold mine subsurface environment.

Authors: Hroboňová Katarína , Špačková Andrea , Ondáková Martina 
Published: August 2019

Abstract
Coumarins can be as a result wine storage and aging in wood drums and they can affect organoleptic characteristics of wine. The aim of this work was to determine the content of coumarins in wine samples originated from Slovak Tokaj wine region. The HPLC method with high specificity, accuracy, precision, and recovery was proposed. SPE sorbents of C18 type, styrene-divinylbenzene copolymer and molecularly imprinted polymers were compared for extraction of six coumarins, coumarin, aesculin, scoparone, scopoletin, 4-methylumbelliferone, and herniarin. Higher recoveries (above 89 %; except aesculin – recoveries higher from 68 %, RSDs less than 6 %) were obtained with selective polymeric sorbent laboratory prepared by molecularly imprinted technology. The results showed that content of coumarins in wine samples are in ng.mL−1 concentration levels and depend on the age and wine puttony.

Abstract
Lipases cleaving oils into fatty acids and glycerol are of great interest for the use in increasing the efficiency of fuels. In this work, a novel lipase from Pseudomonas aeruginosa, P. aeruginosa A12, was isolated by ion-exchange and hydrophobic chromatography. The purity of lipase was shown by electrophoresis and its molecular weight was estimated to be ~ 31.6 kDa. The whole amino acid sequence was analyzed by an LC-MS/MS method. Temperature- and pH-dependent optimum of the enzyme compiled 30 °C and 7.5, respectively. The obtained enzyme exhibited 79 % similarity of amino acid sequence to a lipase isolated from the same strain of P. aeruginosa. Thus, the novel lipase was determined to belong to I.1 subfamily of bacterial true lipases. Three dimensional structure of the isolated lipase isoform was modeled based on obtained sequences. Amino acids forming the catalytic domain were shown in the model. Lid domain is suggested to be in the open conformation. These results provide a potential alternative for enzymatic digestion of fuel oils and serve for the development of fundamental knowledge of lipase activity.

Published: August 2019

Abstract
Smart grid (SG) is the solution to solve existing problems of energy security from generation to utilization. Examples of such problems are disruptions in the electric grid and disturbances in the transmission. SG is a premium source of Big Data. The data should be processed to reveal hidden patterns and secret correlations to extrapolate the needed values. Such useful information obtained by the so-called data analytics is an essential element for energy management and control decision towards improving energy security, efficiency, and decreasing costs of energy use. For that reason, different techniques have been developed to process Big Data. This paper presents an overview of these techniques and discusses their advantages and challenges. The contribution of this paper is building a recommender system using different techniques to overcome the most obstacles encountering the Big Data processes in SG. The proposed system achieves the goals of the future SG by (i) analyzing data and executing values as accurately as possible, (ii) helping in decision-making to improve the efficiency of the grid, (iii) reducing cost and time, (iv) managing operating parameters, (v) allowing predicting and preventing equipment failures, and (vi) increasing customer satisfaction. Big Data process enables benefits that were never achieved for the SG application.
Acute radiation-induced oral mucositis in patients subjected to radiotherapy due to head and neck cancer
Authors: Brzozowska Anna , Gołębiowski Paweł 
Published: August 2019

Abstract
Oral mucositis is a common side effect of radiation therapy for head and neck cancer. Severe mucositis is followed by symptoms, such as extreme pain, mucosal ulceration and consequent limitations in swallowing and achieving adequate nutritional intake. Mucositis may also increase the risk of local and systemic infection and significantly affect quality of life and cost of care. Severe oral mucositis can lead to the need to interrupt or discontinue cancer therapy and thus may have an impact on cure of the primary disease. In spite of all the advances made in understanding the pathophysiology of oral mucositis, there is still no prophylactic therapy with proven efficacy and known risk factors. This review will discuss oral mucositis epidemiology, impact and side effects, pathogenesis, scoring scales and prevention.

Authors: Rogulska Oxana , Tarasova Olga 
Published: August 2019

AbstractStudying the experience of foreign language teachers’ professional training in developed foreign countries opens up new opportunities for improving the system of pedagogical education in conditions of its adaptation to the requirements of the European educational space. Of a significant scientific interest are the progressive achievements of countries that demonstrate a high level of foreign language teachers’ professional training in accordance with international standards; have rich historical traditions of education that contributes to their leading role in science and education at the regional and global levels; have gained considerable experience in the field of foreign language teachers’ professional training in the new socio-cultural conditions. It is emphasized that the language policy of the European Union demonstrates the crucial importance of language learning in the integration processes. It is also underlined that in modern international documents on the modernization of the foreign language teachers’ professional training it is stated that modern educational transformations should facilitate the implementation of a European dimension in the foreign languages teachers’ training. The establishment of new values related to the search for a multicultural, multi-ethnic and multi-linguistic Europe depends to a great extent on the ability of the teacher to develop a European consciousness and an individual sense of moral responsibility in a pluralistic society. The paper presents the results of collective scientific research, in particular, the peculiarities of the foreign language teachers’ professional training in Poland are presented and the recommendations on the creative use of constructive ideas of the progressive experience in the process of updating the system of pedagogical education are outlined.
The Role of Parent’s Participation in Sports on Change in Exercise Level: A Cross-Cultural Comparison
Authors: Alemdağ Ceyhun 
Published: August 2019

Abstract
The family, which is one of the smallest units of the society, has the most important effect on a child’s life. It is known that parents are the initial examples for the child in many ways. This study primarily aims to compare the sports sciences students in Turkey and the United Kingdom in terms of their parents’ participation in sports. The sample consisted of 390 sports sciences students (201 in the UK and 189 in Turkey). The study was conducted with the cross-sectional screening model. The data were collected by the Exercise Stages of Change Questionnaire (ESOCQ) and analysed by Chi-Squared (χ2) test. Within the scope of the study, it was found that the sports sciences students in both countries were rather at the active stage of exercise stages of change in both countries, but the ratio of the students who actively participated in exercise in the UK was higher. The observations from the passive and preparation stages of the participation in exercises were examined and the frequency of the students in Turkey was higher compared to those in the UK. The rates of parent attendance in sports were also higher in the UK, and the active stage was on for the majority of these students from the exercise stages of change. In Turkey, the students whose parents do not attend sports have higher rates than those of the attending parents. In consideration of the sportive achievements, it is quite obvious that it is not enough simply to offer choices to children. Beyond that, another approach is required. The leading action to take can be participating in sports by themselves to become a model for their kids. Accordingly, it is essential that parents should be seen as a social support that may help them develop some new attitudes towards sports at their developmental ages.
The Content of Professional Training of Masters in National Security at the UK Universities
Authors: Braiko Bohdan 
Published: August 2019

AbstractThe article deals with the content of training Masters in National Security at the UK universities. The problem of the state’s national security in the context of the state’s general development and the realization of its national interests has been actualized. It is noted that maintaining the national interests of any state world provides an adequate response to the challenges and threats of today, namely the implementation of an effective national security policy. It is found that the UK’s national security strategy lists all the key threats that the government believes are threatening the state. Terrorism has been the top problem since the terrorist attacks in London in 2007. The proliferation of nuclear weapons and other types of weapons of mass destruction causes much anxiety, too. The UK strategy also includes threats such as transnational organized crime, global instability and conflictogenity (in the Middle East and Africa), global climate change, energy shortages, poverty, etc. The conducted research proves that the UK seeks to identify and eliminate such threats as transnational organized crime, global instability and conflictogenity, global climate change, energy shortages, poverty, etc. The UK National Security Strategy is based on such key values as human rights, the rule of law, a lawful and responsible government, justice, freedom, tolerance and equal opportunity for all. As a result, the UK universities aim to diversify professional training of specialists in national security incorporating into the field such areas as peace or war studies, conflict studies, terrorism, insurgency, etc. The content of professional training for national security specialists, namely masters, provided by King’s College London, the University of Leeds and Coventry University are characterized by the following features: adherence to the nation-wide principles of national security, the conceptual diversity of degree programmes (national security studies; peace and conflict studies; security, terrorism and insurgency), focus on humanities, profession-oriented compulsory modules, a wide range of optional courses, flexible combination of study and work and personal commitments, research challenges, taking into account the dilemmas and challenges of globalization and integration, promotion of human rights, etc. The relevant recommendations have been singled out to improve the content of professional training for such specialists at Ukrainian universities.
“The case”of the philosopher Vasile Băncilă – writings from youth.
Authors: Dur Ion 
Published: August 2019

Abstract
Vasile Băncilă is a thinker to be placed where he fits in the hierarchy of values of Romanian philosophers. Therefore, this text invokes some “start-up frames”, through which we offer a range of accents of the reception of the intellectual and philosophical dowry left by the author. Vasile Băncilă left posterity printed texts, but also thousands of sheets written over four decades of life, unfinished and not ready to be printed. Some of them are from his youth; on some of these focuses this text, namely on what meant for the young philosophy professor Vasile Băncilă the act or the process of philosophizing.
Vasile Pârvan: ideatic nervures of the reformator lessons
Authors: Manolache Viorella , Kozma Andrei 
Published: August 2019

Abstract
The present study resonates with the primacy of the exemplary model of the inaugural lessons in the program/curriculum of critical school achievements, in the spirit of Alexandru Zub question about what the inaugural lessons should say? The answer calls for a return to the Xenopol model, but also for the reopening of the Kogălniceanu’s methodological laboratory, stating the need for any course to be inaugurated through a broad exposure of the field, by drawing attention to the theoretical and methodological horizon, by enumerating the boundaries and limitations of research; but also, by gaining the interest of the audience. Pârvanian historiosophy is decisive in the flow of the so-called method, attaching the teacher’s vocation to the prerogative of the philosopher, and relying on two conjugated attitudes: the first „evolutionary synthesizer of thought”, the second „cosmic valoriser of the world and of life.” Thus, we will insist on the ideo-historical ribbons/nervures of the four inaugural lessons of Vasile Pârvan, presenting them with the decisive remarks about the rethinking of philosophy and history. This approach is circumscribed to the atmosphere of the Centenary of the Romanian Great Union as a means of returning to exemplary models to counter the dysfunctions of functional illiteracy, the confusing and synchronous perspective of teaching history in school, and the program to eliminate the historical dimension of the culture study - exhibited at the anniversary moment of the Romanian culture by Academician Ioan-Aurel Pop.
Profane and sacred love in the writings of Julius Evola
Authors: Dragoman Dragoş 
Published: August 2019

Abstract
Noticing the steep degradation of love in the modern society, Evola makes an effort to overpass the social, commercial or biological conceptions of love and to unravel the forgotten ideas about love. Looking at the current modern situation, few people could imagine love as transcendent, as a force capable of overpassing the limitations of a human being. As emphasized by Evola, the union between the two lovers, when it is conceived as the unification of the opposite tendencies in a sacred union, can find the lost path towards the Unity. By detachment and transmutation, the use of the sexual energy may even lead to supra-natural powers, ecstasies and elevated consciousness.
„Notebook VII”, excerpt from „the story of my poor life”. Inedit writings of Ion D. Sîrbu
Authors: Sîrbu Ion D. 
Published: August 2019

Abstract
„Ion D. Sirbu’s idea of memories dates back, according to his own testimony in 1979,when he decided that: „I will buy a tape recorder. I wish - because I have a special gift of oral storytelling, live speech of heart to heart confession – I wish [...] to „tell” (as in the park, pubs, cemetery) those memories that cannot be written because they were too lived!!”

In 1980-81, Ion D. Sîrbu bought a tape recorder MAJAK 203 and recorded on two ORWO tapes, of 360 m, some of the memories (childhood, adolescence and the early months of his student life in Sibiu). On June 7th, 1989, „urged by the ghosts of my insomnia, I open a new notebook and start - for the first time - to write the story of my poor life. I will not be concerned at all to be precise, the memory began to leave me, nor do I care about my life as reality but as a story: thought, dreamed, told dozens of times and, especially, lived. „
He wrote 75 pages, the latter probably before the end of the month, since, on 1st July, dictates to his wife a letter to David Prodan. The story line „breaks” the day he left for war.
This fragment (ms., Pp. 23-28) and the three letters, all unique, we have included in the volume: Ion D. Sirbu Latest ..., soon printed”. (Toma Velici)
Memory, Fiction and Reality in Antonio Muñoz Molina’s Novels
Authors: Grigore Rodica 
Published: August 2019

Abstract
Often compared to Jorge Luis Borges or even to William Faulkner for the intricate and symbolic structure of his work, the Spanish writer Antonio Muñoz Molina always tried to evaluate within his novels the complex relationship between reality and fiction. The Spanish Rider (1991), one of his most exquisite creations also deals with the significance of memory as far as his protagonist’s evolution and decisions are concerned. Above all these, the novelist analyzes the influence of history on common people’s life and underlines the necessary balance that has to be established between the historical great events and everyday’s choices. His next novel, Full Moon (1997) uses the same aesthetic points of departure, but complicates everything with the details of a specific kind of psychological thriller, the author proving how the seemingly very simple structure of a crime story may turn into an unexpected evaluation of the tragic aspects definying contemporary human condition.
The Bread of God: religious and symbolic aspects of bakery
Authors: Grozea Lucian 
Published: August 2019

Abstract
The present conference discusses the symbolic meaning of bread in the religious mentality of the Ancient Near East. We will find that bread, besides being a food necessary for its existence, also represented a cultural archetype that summed up and assumed in itself either different divinities of Oriental civilizations, or had a ritual-sacrificial character, in order to facilitate man rather immortality.
