The Relationship Between Talent and Success in Theatre and Sport
Authors: Leșe Ana-Cristina 
Published: April 2019

Abstract
The origin of success must be sought in man, in his abilities. In the approached theme, we pay attention towards the athlete and the actor, in the beginning of their career, when the selection because of physic, mental and artistic abilities is made. The inborn need for the endowment of the athlete and actor seems to be a qualitative one and not a quantitative one. What we inherit, the talent is and always has been contested in sports or art.
Cisplatin and beyond: molecular mechanisms of action and drug resistance development in cancer chemotherapy
Authors: Makovec Tomaz 
Published: April 2019

Abstract

Background
Platinum-based anticancer drugs are widely used in the chemotherapy of human neoplasms. The major obstacle for the clinical use of this class of drugs is the development of resistance and toxicity. It is therefore very important to understand the chemical properties, transport and metabolic pathways and mechanism of actions of these compounds. There is a large body of evidence that therapeutic and toxic effects of platinum drugs on cells are not only a consequence of covalent adducts formation between platinum complexes and DNA but also with RNA and many proteins. These processes determine molecular mechanisms that underlie resistance to platinum drugs as well as their toxicity. Increased expression levels of various transporters and increased repair of platinum-DNA adducts are both considered as the most significant processes in the development of drug resistance. Functional genomics has an increasing role in predicting patients’ responses to platinum drugs. Genetic polymorphisms affecting these processes may play an important role and constitute the basis for individualized approach to cancer therapy. Similar processes may also influence therapeutic potential of nonplatinum metal compounds with anticancer activity.

Conclusions
Cisplatin is the most frequently used platinum based chemotherapeutic agent that is clinically proven to combat different types of cancers and sarcomas.

Authors: Porkabiri Z. , Sabaghnia N. , Ranjbar R. , Maleki H.H. 
Published: April 2019

Abstract
Simple lattice design with two replicates was used to evaluate 25 tobacco genotypes. The following eight traits were measured and evaluated: plant height (PH), leaf length (LL), leaf width (LW), leaf number per plant (LN), stem girth (SG), leaf area (LA), dry leaf yield (DLW), and fresh leaf yield (FLW). The genotype by trait biplot for tobacco dataset explained 73% of the total variation of the standardized data. The polygon view of genotype by trait presented for the eight different traits of tobacco genotypes showed six vertex cultivars (G4, G5, G11, G12, G18, and G21). Genotype G21 had the highest values for most of the measured traits. Based on a vector view biplot, strong positive associations among LL, DLW, FLW, and LA were detected while near zero correlations between LL and SG, as well as between LL and PH were observed. Generally, based on ideal genotype and ideal tester biplots, it was demonstrated that the selection for high leaf yield should be performed via leaf length, leaf width, and leaf area traits identified as effective selection criteria for high yielding cultivars.
Genetic Resistance Against Scrapie Disease Related to Lamb Growth Performance Traits
Authors: Ptáček M. , Ducháček J. 
Published: April 2019

Abstract
The objective of the study was to identify the impact of selection on genetic resistance against scrapie disease related to lamb growth performance attributes for Suffolk, Kent, Charollais, and Texel lambs.The allelic genotypes were grouped according to the presence of scrapie resistant allele (ARR): ARR homozygotes, ARR heterozygotes, no presence of ARR allele. The influence of these groups on lamb live weight (LW), musculus longissimus lumborum et thoracis depth (MLLT), and back-fat thickness at 100 days of age was investigated using SAS software. No significant differences for Suffolk and Charollais breeds were detected. Significantly highest LW (34.41 kg) and MLLT (27.80 mm) were noticed for Kent ARR homozygotes lambs, while significantly lowest values were estimated at lambs with absent ARR allele (LW = 33.42 kg, MLLT = 26.68 mm). Significantly lower muscle depth (–0.69 mm) was detected for Texel ARR homozygote compared to ARR heterozygote lambs. As a result, we were unable to detect a consistent evidence for reduced growth performance traits in relation to genetic resistance against scrapie disease. However, the number of animals in some groups caused as a limiting factor. This can be a potential reason of opposed trends in Texel and Kent lambs.
Antibiotic Resistance in Livestock Breeding: A Review
Authors: Laloučková K. , Skřivanová E. 
Published: April 2019

Abstract
Antibiotic resistance represents a serious threat worldwide. When considering the increasing ability of bacteria to effectively resist antibacterial agents, it is necessary to reduce the consumption of antibiotic substances in animal production in order to preserve their effectiveness in the future. Attention should be paid to the multidrug resistant microorganisms’ occurrence, which can be very exhausting for the breeder not only from the economic point of view. Therefore, alternative sources of antibacterials should be considered due to the limited possibilities of using conventional antibiotics in animal breeding, e.g. application of various substances including organic acids, clay minerals, etc. Nowadays, the research in this field also focuses on the combinatory effect of such compounds, which can also find the perspective for use in animal breeding. This article provides an overview of problems connected with the resistance of diverse bacteria to antibiotic treatment in livestock breeding. It emphasises the need for alternate resources usage with the aim to lower the environmental burden caused by overuse of antimicrobials used in subclinical doses in the past and with the expanding bacterial resistance.

Published: April 2019

AbstractThe effect of different label and processing methods of milk thistle on growth performance in broiler rabbits (HYLA, n = 255) fed with different concentration of milk thistle (Silybum marianum) was studied. Four experiments were conducted. Rabbits were fed with different concentrations of 1% non-fermented milk thistle (experimental group E1) and 0.5% fermented milk thistle (experimental group E2), and the results were compared with a control group C (standard feed ration without any supplementation). Each experiment started at 42 days of rabbits’ age and finished at 85 days of age. Observed parameters were: average daily gain, average daily feed consumption, total feed consumption, slaughter live weight, and carcass weight. The best results were showed in experimental group E2 (supplement of 0.5% fermented milk thistle). Significant differences (P<0.05) were recorded in average daily feed consumption, total feed consumption, slaughter live weight, and carcass weight. The results show that 0.5% fermented milk thistle extract supplemented in the feed ration for broiler rabbits has a positive effect on fattening performance.

Abstract
The aim of this work was to determine how two cadmium (Cd) hyperaccumulating plants in feed affect a consumer organism (Rattus norvegicus var. alba). Using inductively coupled plasma optical emission spectrometry (ICP-OES), Cd concentrations were analyzed in Wistar rat (Rattus norvegicus var. alba) tissues. Rats were fed the Cd and Zn hyperaccumulating plants Noccaea caerulescens or Arabidopsis halleri. Rats given Arabidopsis halleri took in 4 times as much Cd as did rats fed Noccaea caerulescens. However, the muscle, intestinal, kidney, spleen, testicular, bone and liver tissues of rats fed A.halleri had 7.3, 5.6, 5.5, 3.5, 3.1, 2.5 and 2.3 times higher Cd concentrations, respectively, than did tissues of rats fed N. caerulescens. A. halleri burdened the muscle, small intestinal, and kidney tissues with Cd to a greater extent than did N. caerulescens. However, the spleen, testes, bone and liver were significantly more burdened with Cd by N. caerulescens. In both experimental groups (rats given N. caerulescens as well as those given A. halleri), the highest Cd concentrations were found (in descending order) in the kidneys > liver > small intestine > spleen > testes > bone > and muscle. This information is vital in situations where, for example, livestock can graze on these plants or when other animals and humans accidentally consume these plants.

Published: April 2019

Abstract
A mathematical model for effective porosity, effective force and permeability was derived using the experimental results. A universal compression machine was used to press oil of jatropha seeds at maximum force 100 kN, pressing vessel diameter 60 mm, initial pressing height 60 mm with different compression speeds ranging from 1 to 50 mm.min−1. The analysis of variance showed significant effects of compression speed on oil yield, oil point deformation, effective porosity and time of oil flow (P < 0.05), while the compression speed effect was not significant on the maximum deformation, oil point force, effective force, flow rate of oil and permeability (P > 0.05). Oil yield decreased significantly with increasing speed hence lower driving effective force. In addition, lower effective porosity required higher effective force to drive oil flow due to lower permeability and flow rate of jatropha seeds oil. Equilibrium force between effective force and oil point force at force 100 kN was determined to be 50 kN with corresponding compression speed approximately 42.74 mm.min−1. This knowledge is important in the industrial technology of oil processing where higher pressure is needed to achieve maximum leakage of oil.

Published: April 2019

Abstract
The study identifies the main beer consumption determinants in the Czech Republic and quantifies their influence on the beer consumption. The analysis covers three areas – identification of the main determinants of Czech beer consumption, quantification of the influence of these factors on beer consumption, and examination of beer consumption forecasting possibilities. Time series of selected variables containing annual data of the 1994–2014 period are analysed. The main determinants are defined in accord with the general economic theory, their influence is measured using an econometric model, and quality of the model for prognostic purposes is verified using an ex-post prognosis. Based on empirical analysis, the price of lager beer, income, and influence of financial crisis were determined as the main determinants of Czech beer consumption. In addition, inelastic reaction of beer consumption on their changes was proven. The estimated model may be considered suitable for prognostic purposes. The Czech beer market and/or beer consumption in the examined period can be considered as specific, but stable.

Published: April 2019

Abstract
In this article the relationship between shadow economy and its’ determinants has been examined. Ten Eastern countries from European Union were chosen due to specific particularities, which may cause higher shadow economy levels in the investigated countries compared with the EU average. Time span of 2003-2016 was selected, as 2017 data has yet to be released at the time of the analysis. Article consists of examination of the current situation and shadow economy trends in Eastern European countries; overview of shadow economy scientific literature followed by hypothesis, which are examined by constructing regression models. Models aim to distinguish the relationship between selected determinants and shadow economy size. Scientific literature analysis revealed that increase of tax burden on labor is seen as a primary reason for the increase of shadow economy, however, such relation has not been identified. Furthermore, results show that unemployment and self-employed people ratio affect shadow economy insignificantly. This suggests that further analysis is needed. Nonetheless, regression model has not rejected the hypotheses of corruption level, income inequality, business freedom and GDP per capita effect on shadow economy. Thus, it can be stated that these variables are determinants of shadow economy in Eastern European countries.

Published: April 2019

Abstract
With growing competition, loyal customers have become the key to the company’s success. Brand loyalty has been a central structure for marketing for almost a century, yet this research topic is still modern and up to date. The aim of this contribution is to answer the research question of whether there are different segments of customers based on demographic and psychographic aspects that would differ in the level of brand loyalty in the company. In other words, do certain groups of company’s customers (according to demographic or psychographic segmentation) have a higher degree of loyalty to the company’s brand? To answer the research question, we have identified hypotheses expressing the existence of a statistical dependence between individual segmentation variable and the level of brand loyalty. Based on statistical testing of established hypotheses, we have confirmed the existence of certain company’s segments that have a higher degree of loyalty.

Examining the Validity of Wagner’s Law versus Keynesian Hypothesis: Evidence from Turkey’s Economy
Authors: Karahan Özcan , Çolak Olcay 
Published: April 2019

Abstract
The direction of the causality relationship between public expenditures and economic growth is one of the most controversial issues of the literature, which also causes great disagreements in the design process of economic policies. There are two approaches to this subject, which are opposite each other and called “Wagner’s Law” and “Keynesian Hypothesis”. This paper aims to examine the validity of Wagner’s law and Keynesian proposition in Turkey using Autoregressive Distributed Lag (ARDL) model over the period of 1998-2016. The findings supported the “Keynesian Hypothesis”, which advocates a one-way causality relationship from public spending to national output. More specifically, the results of the study showed that the effect of public expenditures on economic growth was positive in the short term and negative in the long term. From an economic policy standpoint, it can be argued that policymakers can promote Turkish economic growth through expansionary fiscal policies in the short run.
Load – Displacement Behaviour of a Pile on a Sloping Ground for Various L/D Ratios
Authors: Sivapriya S. V. , Ramanathan Rahul 
Published: April 2019

Abstract
An experimental study was carried out to understand the behaviour of a laterally loaded single pile on a slope with different length/diameter (L/D) ratios driven into cohesionless soil for a relative density of 70%. Static loading was applied in both forward and reverse directions for slopes of 1V:1.5H, 1V:2H, and 1V:2.5H for a constant L/D ratio representing flexible pile behaviour. It was observed that the load ratio (load on a sandy slope to the horizontal ground) decreased with an increase in the slope’s angle. The post-static behaviour of the pile under the same conditions was also studied to evaluate the elastic displacement, which increased with an increase in the slope’s angle. Due to the constant passive resistance under the reverse loading, the lateral load on the slope’s crest was almost equal to the horizontal ground’s condition. The effect of the L/D ratio was studied by varying the length and diameter and by maintaining the other parameter as a constant. The lateral load of a pile increased with an increase in its length and diameter.
ADCP Discharge Measurements on the River Danube: Post-Processing and Correction of Data
Authors: Výleta Roman , Valent Peter 
Published: April 2019

Abstract
Accurate measurements and analyses of river discharges are one of the key tasks of hydrology. Nowadays, the traditional methods of discharge measurements are being supplemented or even replaced by novel approaches that utilize state-of-the-art technologies. One approach, which has recently become very popular in the hydrological practice both in Slovakia and abroad, is a method utilizing the Doppler effect of sound waves. In this study, a dataset of 185 discharge measurements on the River Danube was created using a RiverRay portable Acoustic Doppler Current Profiler (ADCP). All the measurements were taken on the River Danube at four different cross-sections in Slovakia. The measurements were processed using the manufacturer’s WinRiver II software and further adjusted in Agila, which is a specialised third-party post-processing software aimed at correcting measurement errors from ADCP discharge measurements. Currently, some but not all countries lying in the Danube basin have included Agila post-processing in their methodologies. This causes problems and disputes between national water authorities when exchanging information about discharge measurements in the border regions. In order to respond to this problem, the main objective of this study was to compare the results of both original and corrected discharges, which were measured under a number of different circumstances, and to propose recommendations about the suitability of using Agila post-processing for discharge measurements of the River Danube.
Failure of Slender Concrete Columns Due to a Loss of Stability
Authors: Benko Vladimír , Dobrý Jakub , Čuhák Marek 
Published: April 2019

Abstract
The European standard for the design of concrete structures that are likely to lose stability requires taking into account the effects of second order theory. This effect increases the impact of a bending moment due to member deformation and additional eccentricity. Slender members can be calculated by the use of a non-linear method. This approach shows a deficit in global reliability for cases where the concrete columns fail due to the loss of stability before reaching the design resistance in the critical cross-sections. Buckling is a brittle failure which occurs without any warning, and the probability of its formation is markedly influenced by the slenderness of the column. Here, the calculation results are presented and compared with the results from an experiment which was carried out in cooperation with STRABAG Bratislava LTD at the Central Laboratory of the Faculty of Civil Engineering SUT in Bratislava. The columns were designed according to the methods stated in STN EN 1992-1-1, namely, a general non-linear method. The focus of this study is to compare multiple approaches based on codes used in Germany (DIN 1045-1, 2001) and Austria (ÖNORM B 4700, 2001) with the present European code mentioned above. The paper aims to compare the global reliability of slender concrete columns with variable slendernesses of 90 and 160.
Nature-Based Thermal Insulation Materials From Renewable Resources – A State-Of-The-Art Review
Authors: Bozsaky David 
Published: April 2019

Abstract
In the 21st century, global climate change and the high level of fossil energy consumption have introduced changes affecting all sectors of the economy, including the building industry. Reducing energy consumption has become an important task for engineers because 30% of the total energy consumption is used for heating our buildings. Recycling the huge amount of industrial and agricultural by-products has also become urgent because due to their CO2 emissions, their combustion is not a state-of-the-art alternative. Besides rediscovering some long-known, nature-based insulating materials, there are also several research projects that have resulted in new products. In the last century it was relatively easy to review this product range, but nowadays there are so many kinds of nature-based thermal insulating products, there is a need for systematization, and more in-depth knowledge about them is required. The purpose of this paper is to develop a new systematization of nature-based thermal insulation materials, summarize the main knowledge about them, and indicate the direction of recent research and development.
