Published: January 2020

Aortic aneurysm (AA) and especially dissecting aneurism (DAA) represent life threatening medical conditions and vascular reconstruction surgery with the insertion of a vascular prosthetic grafts is often required to save patients life. In this paper we debate over the long term outcome of 23 patients who underwent five to eight years ago an aortic reconstruction surgery with insertion of Dacron grafts. They attended, during 2018, the emergency room of the County Emergency Hospital Pius Brinzeu of Timisoara in terms of patency complications of the prosthesis. Despite slight dilatation of the Dacron graft and of the native aorta, presence of mural thrombi and/or progress of aortic regurgitation, their evolution was satisfactory, without severe complications.

Authors: Gradinaru Luiza Madalina , Vlad Stelian , Drobota Mioara , Spiridon Maria , Istrate Ioan
Published: January 2020

This work reports the activation of polyurethane film surfaces in order to enrich them with polar groups such as -NH2, -OH, -COOH or radicals, which further allows immobilization of several bioactive compounds. UV-activation was used to introduce new groups on the polymer surface without affecting the bulk properties. The current arising species improve the wettability of the PU surfaces as it was observed from the static contact angle measurements. The structure and composition of the new PU surfaces were analyzed by using ATR-FTIR spectroscopy. The results suggested the possibility of modifying the PU surfaces in a shorter time periods, in order to provide many sites to attach other biomacromolecules by polar interaction or hydrogen bonding.

Published: January 2020

The purpose of our study was to analyze the influence of Ti-6Al-4V and Ti-15Zr dental implants, with complex implant designs, on the cortical and trabecular mandibular bone in regards to the stress value and its distribution using finite element analysis. A total of four 3D implant assemblies were modeled, each consisting of implant, abutment, abutment screw, cement layer, and ceramic crown. Implants were modeled with different macrostructure designs with focus on the main thread and microthread design as well as complex geometry details. All implants were inserted in the second molar position in the mandible bone section, consisting of two macro-structures, a 2 mm thick cortical bone and an internal cancellous bone. Results revealed that small variations in the implant design led to a great difference in the stress values and distribution in both cortical and cancellous bone. Our results suggest no major difference between Ti-6Al-4V and Ti-15Zr in regards to the material�s ability to decrease stress in the periimplant bone. However, within the same material, results revealed important differences between thread design and implant geometry concerning the stress values and stress concentration in cortical and cancellous bone in the mandibular model.

Published: January 2020

Dental caries and secondary caries are the most common problems in dentistry. Many studies provided evidence for the anticariogenic effect of fluorides. The incidence of secondary caries is decreased in teeth restored with fluoride releasing materials. The purpose of the present in vitro study is to evaluate the fluoride release and uptake capability of two glass-ionomer cements and two compomers. A total number of 60 specimens were prepared according to the manufacturer�s instructions using silicone molds. The specimens were transferred in plastic containers containing artificial saliva (pH=7), incubated at 37�C for 24 h and divided in three subgroups: control group, varnish treated group and dentifrice treated group. The fluoride ion content was measured on five times during a period of 30 days using an Orion 720A fluoride meter with 9609 BN fluoride ion electrode. The self-curing glass-ionomer cement released the highest amounts of fluoride ions at the beginning and after the one month study period. The samples of the four materials tested in the varnish treated groups showed significant differences compared to their control groups on the second day. Dentifrice treated groups did not show significant differences compared to their control groups, except values measured after 30 days. Application of fluoride varnish produced an increase of fluoride release for the first 24 h in case of all materials. However, results suggest that the use of fluoridated dentifrice would be more effective in caries prevention due to their fluoride uptake capability.

Published: January 2020

The composition of electrical wires and cables is of critical importance in controlling fire risks. In this respect, polyvinylchloride (PVC) composites are extensively used. Yet, PVC composites are multiple systems in which the final properties depend on the nature and size of the reinforcement or flame-retardant agent and the type of lubricant used for their preparation. Thereby, in this study two series of PVC composites, with stearic acid and calcium stearate as lubricants were prepared in parallel, and additivated with various commercial minerals as reinforcement/flame retardant agents, such as calcium carbonate, alumina trihydrate (ATH) and HMH (a mineral of hydromagnesite and huntite). Following the structure (by FT-infrared), thermal behavior (thermal analyses and differential scanning calorimetry) and mechanical properties (dynamic mechanical analyses, tensile strength and elongation at break) of PVC composites, the flame-retardant effect of the selected minerals was investigated by measuring the limiting oxygen index (LOI). Only ATH and HMH-based composites presented higher flame-resistance, relative to the control samples, making them suitable for the proposed application. The contact angle was evaluated for determining the hydrophobicity of composites when using ATH or HMH, to get an opinion about the stability of the materials in moist environments. Finally, SEM was used to determine the homogeneity of PVC samples.

Authors: Florescu Virgil , Rus Dorin , Rece Laurentiu
Published: January 2020

The thermoplastic materials studied are biphasic. They consist of a polymer mass and a short glass fiber, the percentage being between 10 and 30%. We have shown, both analytically and graphically, the evolution of wear occurring on the steel surface in contact with glass fiber-reinforced polymers. The evolution in time of this process depends on the evolution of the friction coefficient in the process of the dry linear contact between different polymers and different types of steels. We have made a connection between the theoretical case and the experimental results. The experimental method used was the wear imprint method through which the wear depth and wear volume were determined. The wear process is complex and is accompanied by adhesion and corrosion phenomena. Any modification of the input parameters such as speed, temperature, load, quantity of glass fibers in the polymer lead at a certain one evolution of the wear behaviour of the composite material.

The increased demand for energy sources is the driving force to convert organic compounds into alternative fuels. Plastic waste disposal affects the environment, since they are not easily recycled and, during the recycling process, they can produce waste ash, heavy metals, or potentially harmful gas emissions. In the plant design for plastic converting into fuel, the chemical reactor is one of the advanced equipment in the field of chemical and process engineering. This study emphasizes the feasibility of pyrolysis process for valorisation plastics by producing energy-efficient products. In this respect, samples of polypropylene, polyethylene and polystyrene were used as models and subjected to pyrolysis processes at 450 �C, in the presence of two types of mesoporous silica materials, MCM-41 and SBA-15, using a modern developed reactor. The use of mesoporous materials increased the calorific value of the obtained oil and gas, thus improving the economic potential of the process end products. This study dealt with the extraction of oil from plastics termed as plastic pyrolysis oil (PPO) and plastics pyrolysis gas (PPG), with a composition rich in different types of hydrocarbons and they can be marketed at much cheaper rates compared to that present in the market.

The aim of this study is to investigate the effect of alloplatic graft and platelet rich fibrin (PRF) , alone or in combination, on bone regeneration in Wistar rats femural defects. Bone defects were prepared in adults male of 20 Wistar rats. In a group of ten, the defect was filled with synthetic ceramic graft as an alloplastic graft; the others 10 were grafted with this alloplastic graft mixed with PRF. All animals were sacrificed on the 90th postoperative day and the femural bones were removed, histologic sections were prepared and the experimental sites were examined microscopically. Histologic examination revealed more new bone formation in the defects filled with alloplastic graft mixed with PRF than in the defects grafted with alloplastic graft alone. The platelet rich fibrin combination effectively induces new bone formation.

PLGA (poly-lactic-co-glycolic acid) nanoparticles represent an important synthetic biocomponent that has the potential to be a promising carrier of drugs, proteins, nucleic acids, due to its biodegradability and minimal side effects. The aim of our study was to observe the antioxidant effect of vitamin E loaded in PLGA nanoparticles administered over a period of 3 weeks in Wistar rats treated with a hypercaloric diet. Glutathione (GSH) and malondiadehyde (MDA) biomarkers determined from liver lysate were analyzed to evaluate the oxidative stress (OS) induced by the hypercaloric diet. The results of our study revealed a statistically significant increase for GSH and vitamin E in group 2 of Wistar rats receiving hypercaloric diet and a daily dose of vitamin E versus group 1 (p[0.005). The antioxidant effect of vitamin E was also observed by the statistically significant decrease of MDA in group 2 of Wistar rats compared with group 1. The daily dose of vitamin E has improved the liver redox status of group 2 Wistar rats.

Patients with total atrioventricular block are of particular interest and prone to severe prognosis unless treated with emergency cardiac pacing. We evaluated different types of leads and their impact on the myocardium, according to the fixation type and pacing method.. A pacemaker patient has a different depolarization pattern and a single chamber pacemaker, has by definition, an intracardiac desynchronization and a different electro-mechanical coupling activity. The presence of late potentials is an independent prognosis factor for cardiac death and electrical vulnerability, especially after myocardial infarction(MI). Late potentials recorded as magnitude vector are the expresion of late depolarization of the surrounding tissue and represent the morfological substrate for reentry. Thus, the incidence of late potentials after pacemaker implant, represents the expresion of electrical vulnerability of the stimulated right ventricular myocardium. In order to deeply study the parameters of magnitude vectors, we noticed the appearance of late potentials during the transitory stimulation in acute atrioventricular block and a restoration of vector normal parameters, after conduction recovery and sinus rhythm conversion.

A bone defect with standard dimensions and localization is produced. Inside this defect a polymer (collagen sponge) impregnated with growing factors, i. e. bone morphogenetic protein - BMP, is introduced. For the witness lot, the same defect is produced, in which the same polymer is introduced, but without any growing factors. It is found that the growing factor not only remains at the initial site, but also has effect on the bone regeneration process. A mathematical model is constructed using a field theory of multifractal type based on the spontaneous symmetry breaking mechanism to exploit such dynamics in biostructures. This mechanism contains all the informational �ingredients�: the multivalent logic based multifractal bit, the algorithm based networks through spatial cnoidal modes of oscilation, etc. In such context, the evolution of all biostructures, through a mechanism that mimics a 3D biological printer, can become operational.

This work presents an experiment aimed at determining the concentration of heavy metals found in the water resources of natural receivers. Heavy metals are very dangerous both for the aquatic life environment, influencing the health of the respective living beings and for the human health especially if there is an open contact between the human and the respective water source. Due to the different technological processes of the treatment plants, the wastewater, however, contains a high concentration of heavy metals, which means that those technological processes do not fully comply with the legal requirements. A good, viable solution that is being researched more and more at present is the use of types of polymeric membranes, suitably adapted in ultrafiltration processes of wastewater. Many of today s advanced researches focus on investigating the retention of heavy metals by membranes. The purpose of this work is to determine the concentration of the main heavy metals such as Fe2+, Zn2+, Cu2+, Pb2+, Ni2+, Mn2+, etc. and other elements such as: Fluorides, Nitrites NO2-N, Phosphates PO4-P, Ammonium NH4-N etc, both before using an organic membrane of PAN from hollow fibers and after cessation of the ultrafiltration experiment to determine the % of the respective metals. can be removed after the ultrafiltration process. The results of the analyzes carried out during the experiment showed that some of the above mentioned chemical elements can be retained by more than 85 % so that a membrane of PAN can reduce the degree of pollution of the waste water, especially where the waste water is directly discharged into natural source of water. At the same time, 14 chemical elements present in the waste water were analyzed and after determining the concentration of the heavy metals after the completion of the experiment it can be confirmed that the use of polymeric membranes is and will be a viable solution for the purpose of protecting the environment and health.

THE EXPERIENCE OF THE EUROPEAN COUNTRIES AND THE USA ON THE LEGAL REGULATION OF THE INTERNAL LABOR ORDER AND THE WAY OF ITS LENDING FOR UKRAINE
Authors: Padalka A.
Published: January 2020

The article analyzes the peculiarities of foreign experience of legal regulation of domestic labor regulations. The specifics of legal regulation of domestic labor regulations in European countries and in the USA are investigated.The ways of borrowing positive foreign experience in the national labor legislation are indicated. Emphasis is placed on the experience of Germany in the regulation of internal labor regulations: 1) a clear consolidation of the rights and responsibilities of employees and employers at a centralized level; 2) implementation of the principle of “mutual trust” of the employee and the employer in the legislation; 3) use of consultations with employee representative bodies in approving internal labor rules; 4) imposing a ban on posting orders on the bulletin board containing the names of employees and the nature of their violations of internal labor rules.In addition, there is an example of France, where for the first time among all other European countries the principle of "bilateral cooperation" ("laissez fair, laissez passer") was enshrined, which limits the state's participation in the economic life of the employer, but provides basic guarantees for the protection of workers' labor rights in this case. their violations. It is also interesting that, within the framework of internal labor regulations, the French legislator introduces the concept of "effective working time", and there is a so-called "compulsory period" during which an employee, without being in the permanent and immediate disposal of the employer, is obliged stay at or near your place of residence so that you can arrive at your place of work and fulfill your responsibilities.It examines the legal regulation of domestic employment in the UK, which is based on contractual and local legal frameworks, which contributes to the dynamic regulation of labor and related relations.It is noted that the rules of domestic labor in the United States are approved, as in England, by a single employer without any consultation with trade unions. United States labor law is two large blocks of legal rules: employment law (labor law) and labor law (collective labor law).
TO SPECIFY THE CONCEPT OF WORTHY WORK
Authors: Panchenko М.
Published: January 2020

The article describes the current scientific approaches of Ukrainian and foreign scientists, within which the concept of decent work is interpreted. The author pays special attention to the critical analysis of the ILO's interpretation of the concept of decent work, to clarify the admissibility of different interpretations of the concept of decent work in practical reality, as well as to outline the main risks of lack of a universal and comprehensive understanding of the corresponding concept.

The approach to understanding the concept of decent work, developed within the framework of the ILO, has been analyzed and it is concluded that it is obviously imperfect, since it is formulated by listing the criteria of this work, which, in fact, do not exhaust the essential content of the corresponding concept.

The scientist draws attention to the problem of determining the criteria of decent work, which are set out in the definition of the relevant socio-legal phenomenon, since they are formulated in too general a form. For example, the criterion for the concept of decent work, which is the requirement for the adequacy of the employment income of the employee, or the criterion of the ability of labor to provide social protection of the employee.

Scientists emphasize that the significance (intrinsic or conceptual value) of decent work is ambiguous, because it depends on who formulates this definition, transferring to it all those expectations of the relevant phenomenon, which are characteristic of the group of persons to whom the person belonging to recognizes the importance of decent work. The difference in approaches to this definition is emphasized from the position of the employer and from the position of the employee.

Important achievement of the article is the formulation of the author's definition of the concept of "decent work”.
LEGAL ASPECTS OF AGREEMENT IN AGRICULTURE

In the article the analysis of legislation of Ukraine on peculiarities of regulation of labor relations of agricultural workers. To resolve certain difficulties, labor relations, adequate safeguards in the implementation and protection of the rights and interests of workers farms conclusions and suggestions for improvement of the existing legislation in this area.

The problems of rural areas are emphasized today, which should recognize the low standard of living and incomes of rural population, the increase in the number of people living below the poverty line, the degradation and extinction of villages, the underdeveloped social and industrial infrastructure. In view of the development and changes in the agricultural sector of the Ukrainian economy, which occurred after the proclamation of the course on market transformations, the author distinguishes forms of organization of agricultural production.

Labor relations that exist in agriculture have their own peculiar features, which should be reflected in the content of the relevant rules of law, especially those aimed at regulating the relations with the formation of personnel potential of enterprises working in the agricultural sector. In order to address the issue of concluding an employment contract in agriculture, it is important to identify its parties, which the author points out.

It has been suggested that there is no consensus today in the specialized literature and in the legislation as to which persons it is advisable to call "specialist" or "specialist" in agriculture. It is proposed to generally call these subjects “agricultural workers”, and a definition of this definition is provided.

Authors: Parinov A.
Published: January 2020

In the article the specifics of compensatory payments in labor law are analyzed. The essence of this legal phenomenon is determined. The author's scientific interpretation of compensatory payments in labor law is outlined.

The author states that the definition and essence of the concept of compensation has not been sufficiently researched in the scientific environment, which makes the current work relevant. In particular, the establishment of the essential features that shape this concept will allow to lay the groundwork for both future research and for the formation of a legislative framework to regulate this sphere of employment relations.

A description of the different approaches to defining this concept is given, in particular, in the economic literature, there are approaches to remuneration when authors try to combine Marxist and contemporary interpretation of wages. There is a scientific debate about the identity of the concepts of pay and wages. The uncertainty of the scientific community on this issue is related to a fairly similar definition of wages, which causes similarities between the two concepts.

It is noted that both in science and in law, two terms are used to refer to one phenomenon: “compensation” and “compensation”. An analysis of these categories indicates that a large number of various payments are simultaneously included in the category of "compensation", while a more narrow understanding should be applied to the concept of "compensation".

LOCAL REGULATION AS A COMPONENT OF LEGAL REGULATION OF LABOR AND DIRECTLY RELATED RELATIONSHIPS
Authors: Sirokha D.
Published: January 2020

The article covers the issues of local regulation as a component of legal regulation of labor and directly related relations. The author argues that the regulation of employment relations at the enterprise can be carried out either individually, in relation to a particular person or employee, or collectively, to all employees or employees of the enterprise or their specific groups. Individual regulation cannot be identified with local legal regulation because of its lack of normative character, even if organizational and legal forms characteristic of local legal regulation are used. The article justifies the idea that local norms do not belong to the number of norms established by the state, they are established directly at enterprises, institutions, organizations, with the participation of labor collectives and trade unions and do not go beyond the general sphere of legal regulation.The author analyzes the provisions of the doctrine of labor law and finds out that local norms organically enter into the legal institutions and branches of national law that determine the status of subjects of labor relations. Local regulation of relations at the enterprise, institution, organization is an integral and important component of the legal regulation of labor and directly related relationships. Relations aimed at limiting the legal status of employees cannot be regulated locally. The author emphasizes that local norms cannot establish new types of legal liability. Local norms reflect typical, widespread, stable employment relationships. They are closer to actual labor relations and are primary in origin in the hierarchy of regulations. Local legal norms should be considered not only as an auxiliary element of centralized regulation, but also as the most important backbone of the development of local rulemaking.

Authors: Pusztai Gabriella , Fényes Hajnalka , Szigeti Fruzsina , Pallay Katalin
Published: January 2020

The interpretation of the phenomenon of student dropout, which represents a waste of a relatively large proportion of human and material capital in the social, individual and institutional domain, is impossible without examining dropout students. In this study, we analysed the DEPART 2018 database, which contains data from 605 Hungarian dropout students. We tried to identify higher education dropout scenarios and pointed out that higher educational dropout is a complex phenomenon. Based on the students' reports on their interpretation and evaluation of their dropouts, four student clusters were created. We compared the groups with their socio-cultural background and their decision to drop out from higher education, and their assessment of that decision. The most important result of the study is that it identifies a new group in addition to the international dropout types, and provides a detailed picture that calls our attention to the diversity of dropout groups, thereby moving beyond the over-generalised image of the dropout student.
At the Crossroad of Cultures: Education and Identity of Hungarian Deaf Learners in Romania
Authors: Belényi Emese
Published: January 2020

Deaf people living in ethnic-national minority situation form a social group whose members have multiple cultural backgrounds. Starting from interpretations which are viewing the deaf child as a member of a distinct cultural and linguistic minority, I studied the education of Hungarian deaf pupils in Romania graduating from the Hungarian Special School in Cluj/Kolozsvár/Klausenburg, with particular regard to the relationship between formal and informal language use in school, communication culture and identity. Methodologically the research is based on life path interviews with Hungarian Deaf Special School graduates, family case studies of two or three generation deaf families and structured interviews with experienced educators. The research results reveal that the educational practice of the concerned educational institution strengthens the pupils' identity awareness and sense of belonging to the Hungarian nation in two distinct, still interconnected ways: on the one hand, through oral language acquisition, nursing the oral Hungarian language skills, and on the other hand through cultivating the Hungarian Sign Language embedded in the deaf culture within the learner community. Nowadays, the conditions and modalities of exercising this role are changing in several respects. The positive educational effects achieved so far can be reinforced and strengthened by educational policies based on the recognition and cultivation of cultural diversity, in all its complex and multifaceted manifestations, including the peculiar needs of ethnic minority deaf learners.
Non-completed Studies: What Factors Affect Academic Success or Failure?
Authors: Kovács Edina
Published: January 2020

The ratio of early school leavers is 12.5 in Hungary, which means 22nd place within the EU28. Early school leaving is an important issue in all European countries, because those who finished their studies after primary education are more likely unemployed and it causes problems for both them and the society. Higher educational drop-out also an important issue, although for other reasons than early school leaving. It is even more difficult to find precise data on this: we don’t know what proportion of the students is affected by this in Hungary. In this study I analyze the database of the Hungarian Youth Research 2016. This survey was conducted on a representative sample of 15-29 year olds, questioning 8,000 people, therefore, early school leavers and higher educational drop-outs should be found among the interviewees. The results show that early school leavers have significantly worse status both financial and cultural. Some of those who had finished only primary school think that they have successfully completed their studies. They answered that despite 18.3 percent of them have started a vocational training, which didn’t finish. Despite the expectations, not much is known about the higher educational drop-outs. 4.5 percent of the interviewees did not answer the question of whether they had completed their studies: they are probably the drop-outs, but we can just assume that. The results show that they have better cultural status than the others.
