Published: January 2017

Abstract
Meat is a staple food for a large part of the population and excessive consumption is often done, with serious repercussions on health. But there are situations where even the occasional meat intake can affect the health of the population, if the products have not been verified for sanitary standards. Trichinosis is an example for this situation. Romania has a significant number of cases compared to other European countries. In Constanta County trichinosis incidence is increasing continuously in 2009-2013. Considering these data we can say that prevention and control measures are not sufficient for this pathology.

Abstract
Our study was conducted by consulting angioCT sites made on a CT GE LightSpeed VCT64 Slice CT and a CT GE LightSpeed 16 Slice CT, following the path and relationships of the descending thoracic aorta against the vertebral column, outside diameters thereof at the thoracic vertebrae T4, T7, T12 and posterior intercostal arteries characteristics. The origin of of the descending thoracic aorta we found most commonly on the left flank of the lower edge of the vertebral body T4, but I have encountered cases where it had come above the lower edge of T4 on level of intervertebral disc T4-T5 or even at the upper edge of T5 vertebral body. At thoracic vertebra T4, on a total of 30 cases, the descending thoracic aorta present a diameter of 20.0 to 32.6 mm, values that correspond to male gender and to females diameter ranging from 25.5 to 27, 4 mm. At level of T7 thoracic vertebra, thoracic aorta present a diameter of 19.6 to 29.5 mm, values found in men, in women the diameter being from 21.9 to 25.2 mm. At thoracic vertebra T12, on a total of 27 cases, the descending thoracic aorta present a diameter of 17.6 to 27.7 mm, in males the diameter was from 17.6 to 27.7 mm and females diameter ranging from 21.1 to 25.2. The length of the descending thoracic aorta was from 18.40 to 19.41 cm.

Internal quality evolution of a large test system – an industrial study
Authors: Kovács Attila , Szabados Kristóf 
Published: January 2017

Abstract
This paper presents our empirical observations related to the evolution of a large automated test system. The system observed is used in the industry as a test tool for complex telecommunication systems, itself consisting of more than one million lines of source code. This study evaluates how different changes during the development have changed the number of observed Code Smells in the test system. We have monitored the development of the test scripts and measured the code quality characteristics over a five years period.
The observations show that the introduction of continuous integration, the existence of tool support for quality improvements in itself, changing the development methodologies (from waterfall to agile), changing technical and line management structure and personnel caused no measurable change in the trends of the observed Code Smells. Internal quality improvements were achieved mainly by individuals intrinsic motivation. Our measurements show similarities with earlier results on software systems evolutions presented by Lehman.
Relationship Between Hyper MV -algebras and Hyperlattices
Authors: Borzooei R. A. , Radfar Akefe , Niazian Sogol 
Published: January 2017

Abstract
Sh. Ghorbani, et al. [9], generalized the concept of MV -algebras and defined the notion of hyper MV -algebras. Now, in this paper, we try to prove that any hyper MV -algebra is a hyperlattice. First we prove that any hyper MV -algebra that satisfies the semi negation property is a hyperlattice. Then with a computer program, we show that any hyper MV -algebra of order less than 6, is a hyperlattice. Finally, we claim that this result is correct for any hyper MV -algebra.

Dualities in Nonholonomic Optimization
Authors: Udrişte Constantin , Constantinescu Mădălina , Ţevy Ionel , Dogaru Oltin 
Published: January 2017

Abstract
This article deals with optimizing problems whose restrictions are nonholonomic. The central issue relates to dual nonholonomic programs (what they mean and how they are solved?) when the nonholonomic constraints are given by Pfaff equations. We emphasize that nonholonomic critical points are not the classical ones and that the nonholonomic Lagrange multipliers are not the classical (holonomic) Lagrange multipliers. Topological significance of Lagrange multipliers and dual function theory introduced by EDO and EDP are key results. Also new Riemannian geometries attached to a given nonholonomic constrained optimization problem are introduced. The original results are surprising and include: (i) aspects derived from the Vranceanu theory of nonholonomic manifolds, and from the geometric distributions theory, (ii) optimal problems in Darboux canonical coordinates.
Process and Product Innovation and the Role of the Preference Function
Authors: Hoefele Andreas 
Published: January 2017

Abstract:
In this paper I investigate the relationship between firms’ investment in product and process innovation, in particular how this relationship is affected by the consumer’s valuation for variety. Depending on the strength of the consumer’s value of variety, the aggregate demand increases with a higher degree of product innovation, which I call the market-expansion effect. I show that the two types of investment are positively related if the market expansion effect is strong.
Antifungal potential of thyme essential oil as a preservative for storage of wheat seeds
Authors: Anžlovar Sabina , Likar Matevž , Koce Jasna Dolenc 
Published: January 2017

AbstractPlant essential oils are potential food preservatives due to their inhibitory effects on bacterial and fungal growth. Antifungal activities of common thyme (Thymus vulgaris) essential oil were tested against endophytic fungi grown from wheat (Triticum aestivum) grain, molecularly identified as Alternaria alternata, Alternaria infectoria, Aspergillus flavus, Epicoccum nigrum and Fusarium poae. Their susceptibility to thyme essential oil was tested in vitro, and ranged from fungicidal to fungistatic. Treatment combinations of prior grain surface sterilization with hypochlorite and direct/indirect treatment with the essential oil were used, which showed strong effects on infection incidence and germination. Direct soaking of the wheat grain in the essential oil was particularly effective, but inhibited both fungal growth and seed germination. In contrast, indirect treatment of the grain with the essential oil (i.e., fumigation) inhibited fungal growth without negative effects on seed germination. In combination with grain surface sterilization with hypochlorite, indirect treatment with thyme essential oil reduced these fungal infections even more. Since thyme essential oil is safe for plants and consumers, in the form of fumigation it could be used as a protectant of storage containers for wheat grain intended for sowing and for food production.

High Accuracy Compact Operator Methods for Two-Dimensional Fourth Order Nonlinear Parabolic Partial Differential Equations
Authors: Mohanty Ranjan Kumar , Kaur Deepti 
Published: January 2017

Abstract
In this study, we develop and implement numerical schemes to solve classes of two-dimensional fourth-order partial differential equations. These methods are fourth-order accurate in space and second-order accurate in time and require only nine spatial grid points of a single compact cell. The proposed discretizations allow the use of Dirichlet boundary conditions only without the need to discretize the derivative boundary conditions and thus avoids the use of ghost points. No transformation or linearization technique is used to handle nonlinearity and the obtained block tri-diagonal nonlinear system has been solved by Newton’s block iteration method. It is discussed how our formulation is able to tackle linear singular problems and it is ensured that the methods retain their orders and accuracy everywhere in the solution region. The proposed two-level method is shown to be unconditionally stable for a class of two-dimensional fourth-order linear parabolic equation. We also discuss the alternating direction implicit (ADI) method for solving two-dimensional fourth-order linear parabolic equation. The proposed difference methods has been successfully tested on the two-dimensional vibration problem, Boussinesq equation, extended Fisher–Kolmogorov equation and
Kuramoto–Sivashinsky equation. Numerical results demonstrate that the schemes are highly accurate in solving a large class of physical problems.
Estimation of the firm‘s balance sheet channel effects during the economic crisis: Case of Croatia
Authors: Šagovac Mislav , Šikić Luka 
Published: January 2017

Abstract
Economic theory recognizes the importance of the firm’s balance sheet channel. This stands in stark contrast to the neoclassical theory of investment. This paper analyses the response of firms to the economic crisis in the sample of Croatian firms. Our main variables of interest are investment and employment. We estimated the OLS model that accounts for a heterogeneous response to the crisis shock of differently leveraged firms. The empirical model is augmented so that it accounts for industry and county effects. The robustness checks are performed for different dependent as well as control variables and interactions. The results strongly and robustly confirm the importance of the firm’s balance sheet channel.
Is there a housing wealth effect in European countries?
Authors: Časni Anita Čeh 
Published: January 2017

Abstract
In this study, a housing wealth effect on personal consumption is assumed and tested on 16 selected European countries using an estimator developed for dynamic heterogeneous panel data analysis. Empirical estimates have shown that there is a long-run and a short-run housing wealth effect in analysed countries. The elasticity of real private consumption to changes in real disposable income has shown to be positive and statistically significant as well as the elasticity of consumption to changes in real housing wealth. Therefore, the research hypothesis of this paper of a statistically significant and positive long-term relationship between housing wealth and private consumption in the analysed countries was confirmed.
ABA pretreatment can alter the distribution of polysomes in salt-stressed barley sprouts
Authors: Szypulska Ewa , Weidner Stanisław 
Published: January 2017

Abstract
The study analyzed caryopses of barley (Hordeum vulgare) cv. Stratus. Caryopses were germinated in darkness at 20°C in three experimental setups: (a) in distilled water for 24 hours, followed by 100 mM NaCl for another 24 hours (salinity stress, SS), (b) in 100 μM of abscisic acid for the first 24 hours, followed by rinsing with distilled water to remove residual ABA, and in 100 mM NaCl for another 24 hours (ABA pretreatment + salinity stress, ABAS), (c) in distilled water only (control, C). Changes in the content of free polysomes (FP), membrane-bound polysomes (MBP), cytoskeleton-bound polysomes (CBP) and cytomatrix-bound polysomes (CMBP) were examined in barley sprouts germinated in SS and ABAS treatments for 48 hours. In salt-stressed barley sprouts, the concentrations of membrane-bound and cytoskeleton-bound polysomes (MBP, CBP and CMBP) decreased significantly, whereas an increase was noted only in the free polysome (FP) fraction. ABA pretreatment altered the distribution of polysomes in stressed plants. The content of cytoskeletonbound polysomes (CBP and CMBP) increased, FP levels decreased, whereas no changes in MBP content were observed in response to ABA treatment. Our results suggest that plants respond to salt stress by increasing the concentrations of free polysomes that are probably released from damaged cell structures, mainly membranes. Our present and previous findings indicate that ABA could inhibit the release of FP in stressed plants by enhancing polysome binding to the cytoskeleton.

Authors: Beinaroviča Anna , Gorobecs Mihails , Ļevčenkovs Anatolijs 
Published: January 2017

Abstract
The present paper deals with the use of systems and devices with artificial intelligence in the motor vehicle driving. The main objective of transport operations is a transportation planning with minimum energy consumption. There are various methods for energy saving, and the paper discusses one of them – proper planning of transport operations. To gain proper planning it is necessary to involve the system and devices with artificial intelligence. They will display possible developments in the choice of one or another transport plan. Consequently, it can be supposed how much the plan is effective against the spent energy. The intelligent device considered in this paper consists of an algorithm, a database, and the internet for the connection to other intelligent devices. The main task of the target function is to minimize the total downtime at intermediate stations. A specific unique PHP-based computer model was created. It uses the MySQL database for simulation data storage and processing. Conclusions based on the experiments were made. The experiments showed that after optimization, a train can pass intermediate stations without making multiple stops breaking and accelerating, which leads to decreased energy consumption.
The Way of Reducing Current Values in Optical Ground Wires at Asymmetrical Faults on Overhead Transmission Lines
Authors: Egamnazarov Georgiy 
Published: January 2017

Abstract
Given the fact that the installing costs of an optical ground wire on overhead lines directly depend on its cross-section, which in turn depends on the level of fault current it should withstand, in order to reduce these current values in the optical ground wire, I suggested performing its isolated descents from the end towers of the line with its transition to an optical cable. The research was carried out on the example of a 500 kV overhead line in the National Electric Power Grid. The Method of Symmetrical Components for calculating asymmetrical fault currents was not used; therefore, calculations were carried out on the base of presenting the line as a multi-wire system for the considered case as a five-wire system (optical ground wire, steel ground wire, and three phase wires). Such approach allows taking into account the initial asymmetry of the line parameters and modeling any kind of asymmetrical faults. The analyses of calculated results were performed. The conclusive evidence that the optical ground wire isolated descents from the end towers of the line give the possibility of reducing the level of maximal fault current distribution values in it and therefore its cross section, is presented.
Alternative Energetics DC Microgrid With Hydrogen Energy Storage System
Authors: Zaļeskis Genadijs , Steiks Ingars 
Published: January 2017

Abstract
This paper is related to an alternative energetics microgrid with a wind generator and a hydrogen energy storage system. The main aim of this research is the development of solutions for effective use of the wind generators in alternative energetics devices, at the same time providing uninterrupted power supply of the critical loads. In this research, it was accepted that the alternative energetics microgrid operates in an autonomous mode and the connection to the conventional power grid is not used. In the case when wind speed is low, the necessary power is provided by the energy storage system, which includes a fuel cell and a tank with stored hydrogen. The theoretical analysis of the storage system operation is made. The possible usage time of the stored hydrogen depends on the available amount of hydrogen and the consumption of the hydrogen by the fuel cell. The consumption, in turn, depends on used fuel cell power. The experimental results suggest that if the wind generator can provide only a part of the needed power, the abiding power can be provided by the fuel cell. In this case, a load filter is necessary to decrease the fuel cell current pulsations.

Published: January 2017

Abstract
Hotels offer different types of services which have different impacts on the users’ satisfaction and have an influence in various extents on decision making, when it comes to the selection of hotels. As a part of research, empirical analysis based on the importance of different services which hotels provide, was conducted. The idea of research is to determine the importance of different types of services for users. The survey was conducted on a sample of 850 respondents in Serbia. The study used AHP methodology which is used in the decisionmaking process analysis and is suitable for studies defining the rank of relevance of individual elements. The obtained results presented in the study provide information such as, what services offered by hotels have the greatest importance for users. Based on the obtained results in empirical research, and by applying cluster analysis, two different segments of hotel guests are identified based on the preferred services. Segments are statistically different and can represent various targets in the hotel business policy.
Accounting Regulation of Financial Reporting By Small and Medium-Sized Entities with No Public Accountability
Authors: Škobić Tanja 
Published: January 2017

Abstract
The establishement of uniform rules and principles for the recognition and evaluation, requirements for presentation and disclosure of elements of the financial statements provides global comparability, harmonisation and high quality financial reporting. Taking into account the simpler requirements of small and mediumsized entities in relation to large entities, the International Accounting Standards Board (IASB) has created a financial reporting standard to meet the needs and capabilities of small and medium-sized entities with no public accountability, which, although the reduced volume and simplified requirements, does not diminish the quality or transparency of financial reporting. The author aims to point to the justification of the need to establish a standard for medium and small entities, analyzes its basic characteristics and examines the relations with full standards and EU regulations. Mandatory application of the standard for small and medium entities in the Republic of Serbia is justified, but other conditions are also required for its successful implementation, which are not provided due to the alternative use of national legislation that is incomplete and vague, and inconsistent with the standards, concludes the author.
The Dynamics Of Small Towns In France
Authors: Jousseaume Valérie , Talandier Magali 
Published: January 2017

AbstractThis article is based on a renewed, unified functional definition of France’s urban hierarchy. Our ranking defines small towns exclusively in terms of their commercial and service functions, not according to size (population or jobs). Accordingly small towns are characterized by their function both in terms of education (presence of a high school), healthcare (a hospital with an operating theatre) and trade (a supermarket with floorspace exceeding 2,500 square metres). The population of small French towns identified using these criteria ranges from 6,200 to 35,500, with 3,500 to 19,000 jobs, depending on their regional context. Large hub-bourgs, defined as places hosting a secondary school, supermarket and nursing home, emerge as the lower limit of the urban world, interfacing with the countryside. In several ways they might count as ‘very small towns’, with a population ranging from 2,400 to 13,500, and 1,000 to 4,700 jobs. The article then analyses the population dynamic of small towns in mainland France over the past 50 years. This period has witnessed far-reaching changes: an urban then metropolitan model has gradually taken shape and gathered strength. In recent years this process has gone hand-in-hand with the demographic renewal of rural areas.
