Abstract

Camelina sativa is well known due to high content of polyunsaturated fatty acids in its oil. Till now this oil has been studied mainly for applications as raw material for synthesis of resins, biodiesel and hydrocarbon fuels. This study examines the oxidative stability of cold-pressed Camelina sativa (also known as camelina, false flax or gold-of-pleasure) oil and its extracts of spices. Despite the high content of polyunsaturated fatty acids, Camelina sativa oil appeared more rigid against oxidation than rapeseed or flax oil. Extracts of different spices were prepared by maceration in camelina oil at room temperature for 24 h. The stability of extracts was determined under accelerated oxidation conditions and monitored by peroxide values. Most of the tested additives (e.g., bay leaves, allspice, clove, barley sprouts, coriander, ginger) did not influence or even decreased oxidative stability of the oil. However, oil with thyme additive demonstrated remarkably higher stability then Camelina sativa oil alone. Press-cakes of camelina seeds were extracted with two polar solvents (ethanol or water) and their mixtures under variable conditions (room temperature or reflux). Prepared polar extracts of press-cakes were characterised by total polyphenol content (Folin–Ciocalteu method) and antiradical activity against 1,1-diphenyl-2-picryl hydrazyl and galvinoxyl.

Published: January 2018

Abstract
Evaluation is a very complex process, which involves a continuous effort to reduce subjectivity from the evaluation procedure in giving grades, scores, marks, percentages etc. The assessment of the instructional process is a controversial topic due to the human factor involved in this process of valorization of learning outcomes. The issue in question breeds discussions on morality, since the future of the testees depends on the facts of examination and of the factually proved objectivity. Evaluation is therefore a pedagogical concept that transcends the definition of measure and the appreciation of the students’ performance. It refers to the process of determining and assessing learning outcomes by revealing the contribution of each resource in the teaching-learning process. The purpose of this paper is to point out some of the major elements of the evaluation process in the context of enhancing the quality of the educational act.
Risk of Interest Rates at the Level of Commercial Banks in Romania
Authors: Sbârcea Ioana Raluca 
Published: January 2018

AbstractThe banking system in Romania is a banking system under development, subject to fluctuations that exist on the market more than on more developed banking systems, fluctuations that can generate losses for banks if they are not properly managed. The losses that may be generated by these fluctuations, known as market risk, refer to the significant fluctuations in three indicators, namely the interest rate, the exchange rate and the asset price. In this article, I will analyse the interest rate risk from a conceptual point of view and the indicators that mitigate this risk. The analysis also contains a study of this risk among commercial banks in the system to highlight the level of risk and possible effects of its manifestation. I calculated and analysed the interest rate risk indicators, individually for the first three banks in the system, but also to comparatively, in order to highlight the existing differences.
Shielding Efficiency of a Fabric Based on Amorphous Glass-Covered Magnetic Microwires to Radiation Emitted by a Mobile Phone in 2G and 3G Communication Technologies

Published: January 2018

Abstract
A dual band mobile phone model was used to check the shielding properties of an amorphous ferromagnetic textile against the radiation emitted by the handset. Two frequencies belonging to the 2nd and 3rd generation of mobile emission technologies were used, 897 MHz and 1950 MHz. The specific absorption rate (SAR) of energy deposition in a human head phantom was measured in standardized conditions. The textile contained micrometric-diameter wires of a ferromagnetic mixture embedded in a thin glass coat and weaved in a specific way. A set of fabric orientations and configurations (layering) were provided in the experiment in order to achieve a better shielding to the phone’s radiation. Compared with the non-shielded handset, SAR deposited in the head while using the fabric-covered phone could be decreased up to 30 % of its initial value – in case of 2G technology and up to 24 % – in case of 3G technology. This type of material shows one of the highest shielding efficiencies of the electric-field component in near-field exposure conditions reported until now. A cubic curve of SAR decrease in depth of the head was revealed in both uncovered and covered handset, the effect of shielding being larger at the higher frequency.
Accuracy Assessment in Determining the Location of Corners of Building Structures Using a Combination of Various Measurement Methods
Authors: Krzyżek Robert , Przewięźlikowska Anna 
Published: January 2018

Abstract
When surveys of corners of building structures are carried out, surveyors frequently use a compilation of two surveying methods. The first one involves the determination of several corners with reference to a geodetic control using classical methods of surveying field details. The second method relates to the remaining corner points of a structure, which are determined in sequence from distance-distance intersection, using control linear values of the wall faces of the building, the so-called tie distances. This paper assesses the accuracy of coordinates of corner points of a building structure, determined using the method of distance-distance intersection, based on the corners which had previously been determined by the conducted surveys tied to a geodetic control. It should be noted, however, that such a method of surveying the corners of building structures from linear measures is based on the details of the first-order accuracy, while the regulations explicitly allow such measurement only for the details of the second- and third-order accuracy. Therefore, a question arises whether this legal provision is unfounded, or whether surveyors are acting not only against the applicable standards but also without due diligence while performing surveys? This study provides answers to the formulated problem. The main purpose of the study was to verify whether the actual method which is used in practice for surveying building structures allows to obtain the required accuracy of coordinates of the points being determined, or whether it should be strictly forbidden. The results of the conducted studies clearly demonstrate that the problem is definitely more complex. Eventually, however, it might be assumed that assessment of the accuracy in determining a location of corners of a building using a combination of two different surveying methods will meet the requirements of the regulation [MIA, 2011), subject to compliance with relevant baseline criteria, which have been presented in this study. Observance of the proposed boundary conditions would allow for frequent performance of surveys of building structures by surveyors (from tie distances), while maintaining the applicable accuracy criteria. This would allow for the inclusion of surveying documentation into the national geodetic and cartographic documentation center database pursuant to the legal bases.
Detecting changes in linear regression models with skew normal errors
Authors: Said Khamis K. , Ning Wei , Tian Yubin 
Published: January 2018

AbstractIn this article, we discuss a linear regression change-point model with skew normal errors. We propose a testing procedure, based on a modified version of the Schwarz information criterion, which is named the modified information criterion (MIC) to locate change points in such a linear regression model. Due to the difficulty of derivation of the asymptotic null distribution of the associated test statistic analytically, the empirical critical values at different significance levels are approximated through simulations. Simulations have also been conducted under different changes among parameters of interest with various sample sizes to investigate the performance of the proposed test. Such a procedure has been applied on a NASA data to illustrate the detecting process.
Influence of Main Macroeconomic Factors on the Level of Employment on Different Size Enterprises – The Evidence from the Sector of Transportation and Storage
Authors: Mielcova Elena 
Published: January 2018

Abstract
The main aim of this paper is to verify the hypothesis that the shift in levels of main macroeconomic variables – in this case in levels of GDP and exports – cause shift of employment levels in private sector, and this change is different for smaller enterprises than for “big players”. Calculated estimation will be presented on data from the sector of transportation and storage for four countries – the Czech Republic, Germany, Austria, Poland and Slovakia for the period 2005-2014, which cover the economic crisis in 2008. Countries were selected such that they cover both highly developed countries (Germany and Austria) and former Eastern Bloc countries (Czech Republic, Poland, and Slovakia) of the European Union placed in the close geographic area. Expected results would show different trends in employment levels for different types of enterprises in all countries.
Systematic Analysis of the Current Academic Research on Social Media Marketing
Authors: Klepek Martin 
Published: January 2018

Abstract
With the advent of social media where customers have the technical ability to upload own content the change occurred in some of the communication habits online. This world of constant communication is a challenge for businesses as well researchers. Academic research in this area is bringing valuable insights into people attitudes and behaviour on the social media. What is the current situation and where the research field is heading is a question of high importance. This study uses the systematic approach to reviewing the literature and to show the development of publications produced at Czech universities. Although the results show an increasing number of studies, Czech research is lagging behind other similar countries. Compared with the best countries, it is lagging behind in the number of quotations per article. On the basis of these analyses, suggestions for future research that can help to promote future theory development are proposed.
The Critical Analysis of Profit for its Allocation Decision-Making
Authors: Pakšiová Renáta 
Published: January 2018

AbstractThe decrease of the business property can cause a reduction in the production ability of the enterprise to the extent causing an involuntary closing of business activities. It is usually caused not only by the reported loss, but also by the greater distribution of profits, as is the amount of the real level of the enterprise's distributable profit. A thorough analysis of the reported accounting profit described in this paper should be the starting point for the allocation of profit. It is important to be able to identify and assign a portion of the accounting profit, corresponding to the non-realised profit and fictitious profit, where eventual release outside the enterprise threatens the future performance of the enterprise. These portions of the reported profit do not correspond to the actually made, realised and real production, which is a necessary condition to achieve a real profit to possible safety division to investors.
A Transgressive Approach Towards Agritectural Space – The Idea of Agricultural-Urban Use Settlements
Authors: Kleszcz Justyna 
Published: January 2018

AbstractThe article aims at presenting the phenomenon of transgression of the modern urban space through the formation of new spatial units defining the city in relation to its productive sphere. Due to the gradual departure from the notion of an enclosed city to one that is open and connected to the form of the surrounding countryside, the problem of defining a new notion of modern urban-rural space emerged. One of the first manifestations of this phenomenon is the emergence of new forms of housing that combine urban features with food production. Analysis of examples such as EVA-Laxmeer in Culemborg, Agromere in Almere, Cannery in Davis, Detroit and Philadelphia allowed for the verification of architectural and planning concepts related to urban values as a form of urban development of new agricultural forms. These phenomena can be understood both as a process of tearing the compact tissue of a city or, in the case of a less orthodox approach towards the built environment, as a process of network layering towards self-sufficiency of various structural, functional, energy-related and food production related characters within the unfavourable external conditions.
al-Madīnah or la ville? An architectural & urban “clash of civilizations” – the example of the city of Algiers
Authors: Kobis Rafał 
Published: January 2018

Abstract
The main aim of author was to present the specific features of the architecture and urbanisation of Algiers – the capital of Algeria. The history of the city was marked by two great periods: Muslim domination (especially from the 15th century) and French colonialism (in the years 1830 – 1962). Both of these have left behind numerous traces of architectural and urbanistic thought. The material effect of French domination is the architecture of modern Algiers, which took the form of a French ville, similar to Paris, Lyon or Marseille. On the other hand, the architecture of Algiers also includes the old Arab district – Casbah, that resembles the cities of the Middle East (Madīnah in Arabic), like Istanbul, Cairo or Damascus. Both architectural traditions give the city of Algiers a cosmopolitan and universal character. The threat to the peculiar coexistence of these traditions is the progressive migration from the countryside to the city, which results in the expansion of area of slums, called bidonvilles.

Published: January 2018

Abstract
A facile synthesis of some methyl 5-(arylamino)-4-oxothieno[2,3-b]thiopyran-6-carboxylates 6a–g is achieved via direct reaction of deprotonated methyl 3-(2,5-dichlorothien-3-yl)-3-oxopropanoate with aryl isothiocyanates in anhydrous tetrahydrofuran (THF) under reflux. Upon saponification of 6a,b, the ester group is eliminated, most logically via decarboxylation of the presumably-formed carboxyl group. Structures of the new compounds 6a–g and 7a,b are supported by microanalytical and spectral [NMR, MS electron impact (EI) and HRMS] data.
