The most well-known and simplest example of the frustrated system is antiferromagnetic Ising model on the triangle. Physically, the existence of frustrations means, that one cannot select all three pairs of spins anti-parallel in the basic unit of the triangle. In physics of the interacting particle systems, the vector models are used, which are constructed on the base of the pair-interaction law. Each pair interaction energy between one-component vectors can take two opposite in sign values, excluding the case of zero. Mathematically, the existence of frustrations in system means that it is impossible to have all negative energies of pair interactions in the Hamiltonian even in the ground state (lowest energy). In fact, the frustration is the excitation, which leaves in system, when thermodynamics does not work, i.e. at the temperature absolute zero. The origin of the frustration is the presence at least of one ''unsatisfied'' pair of interacted spins (magnetic moments). The minimal relative quantity of these excitations (relative quantity of frustrations in ground state) can be used as parameter of frustration. If the energy of the ground state is Egs, and summary energy of all energy of pair interactions taken with a positive sign is Emax, that proposed frustration parameter pf takes values from the interval [0,1] and it is defined as pf=(Egs+Emax)/2Emax. For antiferromagnetic Ising model on the triangle pf=1/3. We calculated the parameters of frustration in thermodynamic limit for different 2D periodical structures of Ising dipoles, which were on the ribs of the lattice and interact by means of the long-range dipolar interaction. For the honeycomb lattice pf=0.3415, triangular - pf=0.2468, kagome - pf=0.1644. All dependencies of frustration parameter from 1/N obey to the linear law. The given frustration parameter allows to consider the thermodynamics of all magnetic systems from united point of view and to compare the different lattice systems of interacting particle in the frame of vector models. This parameter can be the fundamental characteristic of frustrated systems. It has no dependence from temperature and thermodynamic states, in which ones the system can be found, such as spin ice, spin glass, spin liquid or even spin snow. It shows us the minimal relative quantity of excitations, which ones can exist in system at T=0. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frustrations" title="frustrations">frustrations</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20of%20order" title=" parameter of order"> parameter of order</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20physics" title=" statistical physics"> statistical physics</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetism" title=" magnetism"> magnetism</a> </p> <a href="https://publications.waset.org/abstracts/80975/frustration-measure-for-dipolar-spin-ice-and-spin-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80975.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Effects of Different Types of Perioperative Analgesia on Minimal Residual Disease Development After Colon Cancer Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lubomir%20Vecera">Lubomir Vecera</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Gabrhelik"> Tomas Gabrhelik</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Tolmaci"> Benjamin Tolmaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Josef%20Srovnal"> Josef Srovnal</a>, <a href="https://publications.waset.org/abstracts/search?q=Emil%20Berta"> Emil Berta</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Prasil"> Petr Prasil</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Stourac"> Petr Stourac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancer is the second leading cause of death worldwide and colon cancer is the second most common type of cancer. Currently, there are only a few studies evaluating the effect of postoperative analgesia on the prognosis of patients undergoing radical colon cancer surgery. Postoperative analgesia in patients undergoing colon cancer surgery is usually managed in two ways, either with strong opioids (morphine, piritramide) or epidural analgesia. In our prospective study, we evaluated the effect of postoperative analgesia on the presence of circulating tumor cells or minimal residual disease after colon cancer surgery. A total of 60 patients who underwent radical colon cancer surgery were enrolled in this prospective, randomized, two-center study. Patients were randomized into three groups, namely piritramide, morphine and postoperative epidural analgesia. We evaluated the presence of carcinoembryonic antigen (CEA) and cytokeratin 20 (CK-20) mRNA positive circulating tumor cells in peripheral blood before surgery, immediately after surgery, on postoperative day two and one month after surgery. The presence of circulating tumor cells was assessed by quantitative real-time reverse transcriptase-polymerase chain reaction (qRT-PCR). In the priritramide postoperative analgesia group, the presence of CEA mRNA positive cells was significantly lower on a postoperative day two compared to the other groups (p=0.04). The value of CK-20 mRNA positive cells was the same in all groups on all days. In all groups, both types of circulating tumor cells returned to normal levels one month after surgery. Demographic and baseline clinical characteristics were similar in all groups. Compared with morphine and epidural analgesia, piritramide significantly reduces the amount of CEA mRNA positive circulating tumor cells after radical colon cancer surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20progression" title="cancer progression">cancer progression</a>, <a href="https://publications.waset.org/abstracts/search?q=colon%20cancer" title=" colon cancer"> colon cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=minimal%20residual%20disease" title=" minimal residual disease"> minimal residual disease</a>, <a href="https://publications.waset.org/abstracts/search?q=perioperative%20analgesia." title=" perioperative analgesia."> perioperative analgesia.</a> </p> <a href="https://publications.waset.org/abstracts/144502/effects-of-different-types-of-perioperative-analgesia-on-minimal-residual-disease-development-after-colon-cancer-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> On q-Non-extensive Statistics with Non-Tsallisian Entropy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petr%20Jizba">Petr Jizba</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Korbel"> Jan Korbel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We combine an axiomatics of Rényi with the q-deformed version of Khinchin axioms to obtain a measure of information (i.e., entropy) which accounts both for systems with embedded self-similarity and non-extensivity.

That is why we decided to focus on creating or finding quantitative and qualitative methodology capable of specifying muscle tone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheologic%20properties" title="rheologic properties">rheologic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=tendo%E2%80%93deformational%20characteristics" title=" tendo–deformational characteristics"> tendo–deformational characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=elasticity" title=" elasticity"> elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertonus" title=" hypertonus"> hypertonus</a> </p> <a href="https://publications.waset.org/abstracts/34403/measurement-of-rheologic-properties-of-soft-tissue-muscle-tissue-by-device-called-myotonometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34403.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">623</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Training Isolated Respiration in Rehabilitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marketa%20Kotova">Marketa Kotova</a>, <a href="https://publications.waset.org/abstracts/search?q=Jana%20Kolarova"> Jana Kolarova</a>, <a href="https://publications.waset.org/abstracts/search?q=Ludek%20Zalud"> Ludek Zalud</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Dobsak"> Petr Dobsak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A game for training of breath (TRABR) for continuous monitoring of pulmonary ventilation during the patients’ therapy focuses especially on monitoring of their ventilation processes.

The present study focused on the effect of lawsone on a plant cell model represented by tobacco BY-2 cell suspension culture, which is used as a model comparable with the HeLa cells. It has been shown that lawsone inhibits the cell growth in the concentration-dependent manner. In addition, changes in DNA methylation level have been determined. We observed decreasing level of DNA methylation in the presence of increasing concentrations of lawsone. These results were accompanied with overproduction of reactive oxygen species (ROS). Since epigenetic modifications can be caused by different stress factors, there could be a connection between the changes in the level of DNA methylation and ROS production caused by lawsone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20methylation" title="DNA methylation">DNA methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=lawsone" title=" lawsone"> lawsone</a>, <a href="https://publications.waset.org/abstracts/search?q=naphthoquinone" title=" naphthoquinone"> naphthoquinone</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species "> reactive oxygen species </a> </p> <a href="https://publications.waset.org/abstracts/11365/dna-methylation-changes-caused-by-lawsone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11365.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Defectoscopy of Reinforced Concrete Structures with Using an Ultrasonic Method for Failure Monitoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabina%20%20Hublova">Sabina Hublova</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristyna%20Hrabova"> Kristyna Hrabova</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Cikrle"> Petr Cikrle</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainable development and preservation of existing buildings are becoming increasingly important worldwide. In order to reduce the amount of CO2 emissions in the air and to reduce the amount of waste from building structures, we can predict an increasing demand for maintenance of some existing buildings in the future. The use of modern diagnostic methods, which allow detailed determination of the properties of structures, the identification of critical points, could be the great importance for the better assessment of existing structures. Non-destructive methods could be one of the options. From these methods, ultrasonic appears to be a highly perspective method, thanks to which we are able to identify critical points of an element or a structure.

The Ti6Al4V alloy was treated by nitrogen ion implantation at fluences of 2·10<sup>17</sup> and 4·10<sup>17</sup> cm<sup>-2</sup> and at ion energy 90 keV. The depth distribution of the nitrogen was investigated by Rutherford Backscattering Spectroscopy. The gradient of mechanical properties was investigated by nanoindentation. The continuous measurement mode was used to obtain depth profiles of the indentation hardness and the reduced storage modulus of the modified surface area. The reduced storage modulus and the hardness increase with increasing fluence. Increased fluence shifts the peak of the mechanical properties as well as the peak of nitrogen concentration towards to the surface.

The research sample consisted of 333 (166 males, 167 females) elementary and high school students at the age between 10 and 19 years (m=14.98, sd=1.77). Using stepwise regression analysis, we assessed the influence of demographic variables (gender and age) and parenting styles. Age and gender together explained 26.3% of game addiction variance (F(2,330)=58.81, p<.01). By adding four aspect of parenting styles (inconsistency, involvement, control, and warmth) another 10.2% of variance was explained (∆F(4,326)=13.09, p<.01). The significant predictor was gender of the respondent, where males scored higher on game addiction scale (B=0.70, p<.01), age (β=-0.18, p<.01), where younger children showed higher level of addiction, and parental inconsistency (β=0.30, p<.01), where the higher the inconsistency in upbringing, the more developed game playing addiction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=parenting%20styles" title=" parenting styles"> parenting styles</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20games" title=" video games"> video games</a>, <a href="https://publications.waset.org/abstracts/search?q=addiction" title=" addiction"> addiction</a> </p> <a href="https://publications.waset.org/abstracts/46275/parenting-styles-and-their-relation-to-videogame-addiction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46275.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Effect of Structure on Properties of Incrementally Formed Titanium Alloy Sheets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Novakova">Lucie Novakova</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Homola"> Petr Homola</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaclav%20Kafka"> Vaclav Kafka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Asymmetric incremental sheet forming (AISF) could significantly reduce costs incurred by the fabrication of complex industrial components with a minimal environmental impact. The AISF experiments were carried out on commercially pure titanium (Ti-Gr2), Timetal (15-3-3-3) alloy, and Ti-6Al-4V (Ti-Gr5) alloy. A special testing geometry was used to characterize the titanium alloys properties from the point of view of the forming zone and titanium structure effect. The structure and properties of the materials were assessed by means of metallographic analyses and microhardness measurements.The highest differences in the parameters assessed as a function of the sampling zone were observed in the case of alpha-phase Ti-Gr2at the expense of the most substantial sheet thinning occurrence. A springback causes a smaller stored deformation in Timetal (β alloy) resulting in less pronounced microstructure refinement and microhardness increase. Ti-6Al-4V alloy exhibited early failure due to its poor formability at ambient temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incremental%20forming" title="incremental forming">incremental forming</a>, <a href="https://publications.waset.org/abstracts/search?q=metallography" title=" metallography"> metallography</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a> </p> <a href="https://publications.waset.org/abstracts/5510/effect-of-structure-on-properties-of-incrementally-formed-titanium-alloy-sheets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5510.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">450</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Laser Beam Micro-Drilling Effect on Ti-6Al-4V Titanium Alloy Sheet Properties </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petr%20Homola">Petr Homola</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20R%C5%AF%C5%BEek"> Roman Růžek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laser beam micro-drilling (LBMD) is one of the most important non-contact machining processes of materials that are difficult to machine by means oeqf conventional machining methods used in various industries.

Two various process configurations were verified with a focus on laser damages in back-structure parts affected by the process. The effects of the LBMD on the material properties were assessed by means of tensile and fatigue tests and fracture surface analyses. Fatigue limit of LBMD configurations reached a significantly lower value between 15% and 30% of the static strength as compared to the reference raw material with 58% value.

This information should be part of every curriculum computer science education in primary and secondary schools. Therefore, the work focuses on the education of pupils in primary and secondary schools on the Internet. Analysis of the current state describes approaches to the education of pupils in security issues on the Internet. The paper presents a questionnaire-based survey which was carried out in the Czech Republic, whose task was to ascertain the level of opinion pupils in primary and secondary schools on the issue of communication in social networks. The research showed that awareness of socio-pathological phenomena on the Internet environment is very low. Based on the results it was proposed appropriate ways of teaching to this issue and its inclusion a proposal of curriculum for primary and secondary schools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20security" title="information security">information security</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20space" title=" cyber space"> cyber space</a>, <a href="https://publications.waset.org/abstracts/search?q=general%20awareness" title=" general awareness"> general awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaire" title=" questionnaire"> questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-pathological%20phenomena" title=" socio-pathological phenomena"> socio-pathological phenomena</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20system" title=" educational system"> educational system</a> </p> <a href="https://publications.waset.org/abstracts/16805/general-awareness-of-teenagers-in-information-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16805.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Actually Existing Policy Mobilities in Czechia: Comparing Creative and Smart Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ondrej%20Slach">Ondrej Slach</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Machacek"> Jan Machacek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Zenka"> Jan Zenka</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Hyllova"> Lucie Hyllova</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Rumpel"> Petr Rumpel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the paper is to identify and asses different trajectories of two fashionable urban policies –creative and smart cities– in specific post-socialistic context. Drawing on the case of Czechia, we employ the concept of policy mobility research. More specifically, we employ a discourse analysis in order to identify the so-called 'infrastructure' of both policies (such as principal actors, journals, conferences, events), with the special focus on 'agents of transfer' in a multiscale perspective. The preliminary results indicate faster and more aggressive spatial penetration of smart cities policy compared to creative cities policy in Czechia. Further, it seems that existed translation and implementation of smart cities policy into the national and urban context resulted in deliberated fragmented policy of smart cities in Czechia (pure technocratic view), which might be a threat for the future development of social sustainability, especially in cities that are facing increasing social polarisation. Last but not least, due to the fast spatial penetration of the concept and policies of smart cities, it seems that creative cities policy has almost been crowded out of the Czech urban agenda. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=policy%20mobility" title="policy mobility">policy mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title=" smart cities"> smart cities</a>, <a href="https://publications.waset.org/abstracts/search?q=creative%20cities" title=" creative cities"> creative cities</a>, <a href="https://publications.waset.org/abstracts/search?q=Czechia" title=" Czechia"> Czechia</a> </p> <a href="https://publications.waset.org/abstracts/114602/actually-existing-policy-mobilities-in-czechia-comparing-creative-and-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114602.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Changes in Physical Soil Properties and Crop Status on Soil Enriched With Treated Manure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaclav%20Novak">Vaclav Novak</a>, <a href="https://publications.waset.org/abstracts/search?q=Katerina%20Krizova"> Katerina Krizova</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Sarec"> Petr Sarec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern agriculture has to face many issues from which soil degradation and lack of organic matter in the soil are only a few of them. Apart from Climate Change, human utilization of landscape is the cause of a majority part of these problems. Cattle production in Czechia has been reduced by more than half in recent 30 years. However, cattle manure is considered as staple organic fertilizer, and its role in attempts for sustainable agriculture is irreplaceable. This study aims to describe the impact of so-called activators of biological manure transformation (Z´fix, Olmix Group) mainly on physical soil properties but also on crop status. The experiment has been established in 2017; nevertheless, initial measurements of implement draft have been performed before the treated manure application. In 2018, the physical soil properties and crop status (sugar beet) has been determined and compared with the untreated manure and control variant. Significant results have been observed already in the first year, where the implement draft decreased by 9.2 % within the treated manure variant in comparison with the control variant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=field%20experiment" title="field experiment">field experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=implement%20draft" title=" implement draft"> implement draft</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetation%20index" title=" vegetation index"> vegetation index</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20beet" title=" sugar beet"> sugar beet</a> </p> <a href="https://publications.waset.org/abstracts/120126/changes-in-physical-soil-properties-and-crop-status-on-soil-enriched-with-treated-manure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120126.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Financial Assessment of the Hard Coal Mining in the Chosen Region in the Czech Republic: Real Options Methodology Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Miroslav%20%C4%8Cul%C3%ADk">Miroslav Čulík</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Gurn%C3%BD"> Petr Gurný</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is aimed at the financial assessment of the hard coal mining in a given region by real option methodology application. Hard coal mining in this mine makes net loss for the owner during the last years due to the long-term unfavourable mining conditions and significant drop in the coal prices during the last years. Management is going to shut down the operation and abandon the project to reduce the loss of the company. The goal is to assess whether the shutting down the operation is the only and correct solution of the problem. Due to the uncertainty in the future hard coal price evolution, the production might be again restarted if the price raises enough to cover the cost of the production. For the assessment, real option methodology is applied, which captures two important aspect of the financial decision-making: risk and flexibility. The paper is structured as follows: first, current state is described and problem is analysed. Next, methodology of real options is described. At last, project is evaluated by applying real option methodology.

In this paper we present a literature review on the profitability-risk-capital relationship in banking. Research papers dealing with this topic can be divided into two groups: the first group focusing on a capital-risk relationship and the second group analyzing a capital-profitability relationship. The first group investigates whether the imposition of stricter capital requirements reduces risk-taking incentives of banks based on a simultaneous equations model. Their model pioneered the idea that the changes in both capital and risk have endogenous and exogenous components. The results obtained by the authors indicate that changes in the capital level are positively related to the changes in asset risk. The second group of the literature concentrating solely on the relationship between the level of held capital and bank profitability is limited. Nevertheless, there are a lot of studies dealing with the banks’ profitability as such, where bank capital is very often included as an explanatory variable. Based on the literature review of dozens of relevant papers in this study, an empirical research on banks’ profitability and risk adjustment decisions under new banking rules Basel III rules can be easily undertaken. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bank" title="bank">bank</a>, <a href="https://publications.waset.org/abstracts/search?q=Basel%20III" title=" Basel III"> Basel III</a>, <a href="https://publications.waset.org/abstracts/search?q=capital" title=" capital"> capital</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=profitability" title=" profitability"> profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=simultaneous%20equations%20model" title=" simultaneous equations model"> simultaneous equations model</a> </p> <a href="https://publications.waset.org/abstracts/10074/a-literature-review-on-banks-profitability-and-risk-adjustment-decisions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10074.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Systems of Liquid Organic Fertilizer Application with Respect to Environmental Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hidayatul%20Fitri">Hidayatul Fitri</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20%C5%A0a%C5%99ec"> Petr Šařec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of organic fertilizer is increasing nowadays, and the application must be conducted accurately to provide the right benefits for plants and maintain soil health. Improper application of fertilizers can cause problems for both plants and the environment. This study investigated the liquid organic fertilizer application, particularly digestate, varied into different application doses concerning mitigation of adverse environmental impacts, improving water infiltration ability, and crop yields. The experiment was established into eight variants with different digestate doses, conducted on emission monitoring and soil physical properties. As a result, the digestate application with shallow injection (5 cm in depth) was confirmed as an appropriate technique for applying liquid fertilizer into the soil. Gas emissions resulted in low concentration and declined gradually over time, obviously proved from the experiment conducted under two measurements immediately after application and the next day. Applied various doses of liquid digestate fertilizer affected the emission concentrations of NH3 volatilization, differing significantly and decreasing about 40% from the first to second measurement. In this study, winter wheat crop production significantly increases under digestate application with additional N fertilizer. This study suggested the long-term application of digestate to obtain more alteration of soil properties such as bulk density, penetration resistance, and hydraulic conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid%20organic%20fertilizer" title="liquid organic fertilizer">liquid organic fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=digestate" title=" digestate"> digestate</a>, <a href="https://publications.waset.org/abstracts/search?q=application" title=" application"> application</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia" title=" ammonia"> ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=emission" title=" emission"> emission</a> </p> <a href="https://publications.waset.org/abstracts/157208/systems-of-liquid-organic-fertilizer-application-with-respect-to-environmental-impact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157208.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Phenomenological Ductile Fracture Criteria Applied to the Cutting Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Franti%C5%A1ek%20%C5%A0ebek">František Šebek</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Kub%C3%ADk"> Petr Kubík</a>, <a href="https://publications.waset.org/abstracts/search?q=Jind%C5%99ich%20Petru%C5%A1ka"> Jindřich Petruška</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%C5%99%C3%AD%20H%C5%AFlka"> Jiří Hůlka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present study is aimed on the cutting process of circular cross-section rods where the fracture is used to separate one rod into two pieces. Incorporating the phenomenological ductile fracture model into the explicit formulation of finite element method, the process can be analyzed without the necessity of realizing too many real experiments which could be expensive in case of repetitive testing in different conditions. In the present paper, the steel AISI 1045 was examined and the tensile tests of smooth and notched cylindrical bars were conducted together with biaxial testing of the notched tube specimens to calibrate material constants of selected phenomenological ductile fracture models. These were implemented into the Abaqus/Explicit through user subroutine VUMAT and used for cutting process simulation. As the calibration process is based on variables which cannot be obtained directly from experiments, numerical simulations of fracture tests are inevitable part of the calibration. Finally, experiments regarding the cutting process were carried out and predictive capability of selected fracture models is discussed. Concluding remarks then make the summary of gained experience both with the calibration and application of particular ductile fracture criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ductile%20fracture" title="ductile fracture">ductile fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=phenomenological%20criteria" title=" phenomenological criteria"> phenomenological criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20process" title=" cutting process"> cutting process</a>, <a href="https://publications.waset.org/abstracts/search?q=explicit%20formulation" title=" explicit formulation"> explicit formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=AISI%201045%20steel" title=" AISI 1045 steel"> AISI 1045 steel</a> </p> <a href="https://publications.waset.org/abstracts/15076/phenomenological-ductile-fracture-criteria-applied-to-the-cutting-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15076.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">457</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> The Importance of Teachers´ Self-Efficacy in the Field of Education of Socially Disadvantaged Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Petr%20Safrankova">Anna Petr Safrankova</a>, <a href="https://publications.waset.org/abstracts/search?q=Karla%20Hrbackova"> Karla Hrbackova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The education of socially disadvantaged students is in the long term spotlight of many pedagogical researches in both Czech and foreign environment. These researches among others investigate this topic from the point of view of individual compensatory measure which tries to overcome or remove the social disadvantage. The focus of the study is to highlight the important role of teachers in the education of this specific group of students, among others in terms of their (teachers´) pre-graduate training. The aim of the study is to point out the importance of teachers´ self-efficacy. The study is based on the assumption that the teacher's self-efficacy may significantly affect the teacher's perception of a particular group of students and thereby affect the education of the students. The survey involved 245 teachers from the two regions in the Czech Republic. In the research were used TES questionnaire (with the dimensions personal teaching efficacy – PTE and general teaching efficacy – GTE) by Gibson and Dembo and the semantic differential (containing 12 scales with bipolar adjectives) which investigated the components of teachers' attitudes toward socially disadvantaged students. It was found that teachers’ self-efficacy significantly affects the teachers’ perception of the group of socially disadvantaged students. Based on this finding we believe that it is necessary to work with this concept (prepare teachers to educate this specific group of students) already during higher education and especially during the pre-graduate teachers training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teachers" title="teachers">teachers</a>, <a
