Abstract
Internal resorption was associated with long-term chronic inflammation of the pulp (chronic granulomatous pulpitis). When internal resorption is radiographically confirmed, endodontic treatment becomes a necessity. Vital teeth internal resorption appears radiographically as an oval enlargement of the pulp chamber and root canal with smooth, symmetrical outline. Internal granuloma is assumed to be an effect of the trauma, or pulp inflammation, the ailment is rare, asymptomatic and might progress rapidly, causing perforation.
It is difficult to remove the pulp tissue from the resorptive defect, since this area is not easily accessible for instrumentation. The delay of the endodontic treatment may lead the internal resorption to perforation, thus decreasing the chances of treatment success.
In the following paper, we present a total of two clinical cases with internal granuloma with perforation that have benefited of specific endodontic treatment.

Published: May 2018

Abstract
Soil mining is a major problem of low technology farming and replenishing such loses is one of the problems farmers face. Trials conducted in 2004 and 2005 at Samaru, (11011’N, 07038’E and 686m a.s.l) in the northern Guinea savanna ecology of Nigeria, estimated the response of maize (Zea mays L.) and soyabean (Glycine max (L.) Merr.) intercrops to green manure from the soyabean companion crop at various nitrogen fertility levels. Treatments were a factorial combination of four maize/soyabean mixtures in replacement and additive mixtures as well as their sole crops and four nitrogen rates arranged in randomized complete block (RCBD) in three replicates. Treatments improved the soil’s physical and chemical (soil C: 2 – 10 %; total N: over 100%; CEC: 20-80%) properties in 2005. Maize in replacement mixture had heavier cobs and 100-seed weight than in additive mixtures; while two plants excelled three plants per stand in these yield components and grain yield per hectare. Soyabean in additive mixture had heavier pods and 100-seed weight and seed yield per hectare than in replacement mixture. Crops in three row plots had significantly heavier pods, 100-seed weight, and seed yield than those in two row plots. Yield and yield parameters of maize increased significantly with increase in the rate of N applied while for soyabeans the 60 and 90 kg N ha−1 were similar in yield and yield parameters. Mixtures gave higher than expected LER values of mixed crops. Maize LER values at 60 and 90 kg N ha−1 were higher than 1.00, making soyabean a bonus crop. Total LER for the crops showed that crops in mixtures performed better than combined sole crops at 90 kg N ha−1. Agronomic efficiency was highest at 12:2(A) cropping pattern and 30 kg N ha−1, while replacement mixtures had higher efficiency values at low N application and the 12:2(A) had higher efficiency value at higher N rates.

Published: May 2018

Abstract
Pumpkin processing into puree, juice, candied fruit and pumpkin seed oil results in large amount of by-products. Pumpkins are rich in carotenes, vitamins, minerals, pectin and dietary fibre. The aim of the current study was to evaluate effect of pumpkin pomace and pumpkin residue powder on wheat bread quality. The total content of carotenes was analyzed by spectrophotometric method. The initial increase of pumpkin residue addition indicated increase in loaf volume, which started to decrease at higher amounts. Sensory evaluation (appearance; surface, crust; porosity; texture, crumb; taste, and flavour) of wheat bread with pumpkin revealed very high consumer acceptance except sample with 50% pomace addition. Total carotene content and colour b* value in wheat bread increased by adding pumpkin by-products. It is recommended to add 5% and 10% of pumpkin powder and no more than 30% of pumpkin pomace (calculated per 100 kg of flour) to dough for production of wheat bread with pumpkin by-product additions.

Special aspects of water use in Persian gardens
Authors: Fekete Albert , Haidari Reza 
Published: May 2018

Abstract
The Persian garden is one of the most characteristic and notable element in the Iranian landscape. Considering Iran’s hot and dry climate along with water deficit for plantation, it becomes noticeable how important the art of making gardens is to Iranians.
Water is one of the most crucial elements in the Persian garden, and we can state that gardens would be meaningless without it. Garden applications use water with its various abilities such as life, brightness, cleanliness, light, inertia, and motion, which bring forward numerous feelings in the human soul and enhance mental comfort. Also, its various running structures, such as basins, streams, water creeks, and fountains, provide mental comfort and technical functions.

Published: May 2018

Abstract
We determined the elemental profile of 16 edible mushroom species from the Făget Forest, near Cluj-Napoca, and of 12 species from the Apuseni Mountains. One-way ANOVA showed no difference in the elemental content of mushrooms when the two regions were compared. Some species accumulated high amounts of trace elements, i.e. Boletus edulis (Ag, S, Zn), Macrolepiota procera (Cu), Lactarius volemus (Co), Russula emetica (Mn), Armillariella mellea, and Chantarellus cibarius (Cr). The cadmium content was the highest in the case of Leccinum scabrum and Boletus edulis. These two species presented elevated risk levels for all age-groups when they are consumed regularly.
A Causal Model of Consumer-Based Brand Equity
Authors: Szőcs Attila , Berács József 
Published: May 2018

Abstract
Branding literature suggests that consumer-based brand equity (CBBE) is a multidimensional construct. Starting from this approach and developing a conceptual multidimensional model, this study finds that CBBE can be best modelled with a two-dimensional structure and claims that it achieves this result by choosing the theoretically based causal specification. On the contrary, with reflective specification, one will be able to fit almost any valid construct because of the halo effect and common method bias. In the final model, Trust (in quality) and Advantage are causing the second-order Brand Equity. The two-dimensional brand equity is an intuitive model easy to interpret and easy to measure, which thus may be a much more attractive means for the management as well.

Published: May 2018

Abstract
The telecommunication industry is one of the service industries that is most affected by the problem of subscribers’ churn. Although several techniques have been used to predict customer churn in developed countries, many of those studies used secondary data which are not readily available in Nigeria for researchers. This study investigates how Markov chains help in modelling and predicting the customer churn and retention rate in the Nigerian mobile telecommunication industry. The data generated through the survey were input in the Windows-based Quantitative System for Business (WinQSB) for analysis. The results reveal that in the study area MTN has the highest retention rate (86.11%), followed by GLO (70.51%), Airtel (67%), and Etisalat (67.5%). This result has implications for telecom firms’ strategies for competitive advantage in particular and survival in general.
Businesses and Their Attitudes to Frugal Innovation
Authors: Marosi Ildikó , Katona Ferenc 
Published: May 2018

Abstract
In order to maintain and increase their market share and position in competition, businesses have to adapt to the changes of the environment and they have to innovate. Since the latest economic crisis, Hungarian businesses have been struggling with several problems, particularly the scarcity of both resources and demands. These circumstances lead to the issues of frugal innovation and sustainable development. The aim of this paper is to show the results of a survey on attitudes toward frugal innovation, which was conducted among 216 Hungarian enterprises in the spring of 2015. However, the surveyed businesses are striving to stay in competition in a not too favourable economic environment as most of them have not recognized the chance of frugal innovation.

The History of the Germans from Mérk and Vállaj, Deported to the Soviet Union for Forced Labour 1945–1949
Authors: Tircsi Richárd 
Published: May 2018

Abstract
The deportation - in German: Verschleppung - was a ‘taboo' for a long time. However, the works born since the change of regime provide an excellent and overall picture about this painful historical act. At the same time, it is desirable to get a more precise picture by examining the detailed history of the deportation in the case of the individual settlements. Merk and Valla), the Swabian settlements in the Szatmar region, in the eastern part of the country, lie on the periphery in several aspects. Still, considering the numerical proportion of their population, the most displaced persons were deported by the Soviets, as war criminals, from here in 1945 - a quarter of whom never saw their beloved ones and home country again. It is the particular tragedy of this fact that those deported were at least as much bound to their recipient country, the Hungarian nation, as to their German nationality. They are not criminals of war but victims of the war of racial discrimination. ‘Who will be responsible for these people suffering innocently?’ - puts the question Ferenc Juhasz, parish priest in Merk at that time. Giving an answer is the task of all of us. The paper seeks to explore a segment of the micro-texture of the country-wide, and even wider, regional trauma of this community, based on diary excerpts from the period as well as on individual, specialized literature research.

Authors: Cernousek Stépán 
Published: May 2018

Abstract
The study presents a virtual tom of the Gulag camp (www.gulag.cz <http://www.gulag.cz>), which consists of the 3D visualization of the labour camp and the panoramic toms of all types of barracks. It is a unique opportunity to familiarize with the conditions, to see how Gulag camps really looked like, especially as there is no museum built from former Gulag camps in Russia today. The description of everyday life in the camp is illustrated by witnesses’ testimonies. The tour is accompanied by a general overview of the Gulag system and the stories of Czechoslovak, Hungarian, and Polish citizens arrested in the Gulag. The virtual tour is the result of three Czech expeditions to the furthest flung parts of Siberia (in 2009, 2011, and 2013), aiming to map what has remained of the abandoned Gulag camps in those areas.
‘Access to Justice’ and the Development of the Van Gend En Loos Doctrine: The Role of Courts and of the Individual in EU Law
Authors: Daminova Nasiya 
Published: May 2018

Abstract
The ‘access to justice’ within the meaning of the Treaty of Lisbon and the pertinent CJEU jurisprudence is primarily seen as access to the EU judicial system, i.e. to the EU Member States’ national courts applying the EU Law or/and the CJEU. The concept of ‘access to justice’ is therefore developing such premises of the Van Gend en Loos judgment as direct effect, vigilance of the EU individual, and the symbiotic relationship between the CJEU and national courts via the preliminary reference procedure. This work aims to explore the development of two basic ideas of Van Gend en Loos, i.e. granting directly enforceable EU rights to individuals and authorizing national courts to protect those rights, in light of the ‘access to justice’ concept within the meaning of the Lisbon Treaty – considering their importance for the realization of EU individuals’ substantive rights and uncertainty surrounding this issue. The paper develops a critique of the theory of justice in EU Law, analyzing if and how the Van Gend en Loos premises influenced the role of individuals making an attempt to claim their EU rights and the role of the EU courts responsible for the enforcement of ‘access to justice’ in the European Union. The claim of this paper is that the new concept of ‘access to justice’ brought by the Lisbon Treaty may be seen as the further development of the Van Gend ‘federalizing effect’ for greater integration through law and an enhanced protection of the individual within the EU multilevel system of Human Rights protection.

Published: May 2018

Abstract
The aim of the paper is twofold - to cover the latest nuclear energy politics events and reveal the dynamics in public perception of nuclear energy by explaining the distribution of attitudes among two notable social groups in Lithuania. The paper is based on two empirical research studies (public polls) carried out in 2013 and 2017. The paper consists of four parts. starts with brief review of main happenings in recent nuclear politics and general tendencies public perception of nuclear energy. Then, it presents cluster analysis of both 2013 and 2017 polls, in which respondents were divided into two groups based on income, education and occupation. Lastly, the paper presents findings and discusses the dynamics of public perception. Comparing the 2017 data with the results of 2013, three main tendencies can be distinguished. First, society became better informed and more critical. Second, the cluster analysis divided respondents in two almost identical groups as in 2013 (with minor peculiarities). Third, the general tendency presupposes the breaking of the irrelevance of nuclear energy as an important factor for energy security in public perception.

Wireless Multimedia Sensor Network Image De-Noising via a Detail-Preserving Sparse Model
Authors: Cui Zhi , Cui Xian-pu 
Published: May 2018

Abstract
In this paper, we propose a Detail-Preserving Sparse Model (DPSM) for de-noising of images that are usually interfered by noise on the Wireless Multimedia Sensor Network (WMSN). Specifically, based on the Structural SIMilarity (SSIM), the DPSM first incorporates a structural-preserving constraint, which enables the structure in the reconstructed image to be close to the ideal no-noise image. In addition, the DPSM adopts a residual ratio as the stopping condition of the sparse solution algorithm (e.g., Orthogonal Matching Pursuit), which enables the structures to be reconstructed under high noise conditions. The experimental results on several WMSN images have demonstrated the superiority of the proposed DPSM method over several well-known de-noising approaches in terms of PSNR and SSIM.
Multi-Stage Encoding Scheme for Multiple Audio Objects Using Compressed Sensing
Authors: Yang Ziyu , Jia Maoshen , Wang Wenbei , Zhang Jiaming 
Published: May 2018

Abstract
Object-based audio techniques have become common since they provide the flexibility for personalized rendering. In this paper a multi-stage encoding scheme for multiple audio objects is proposed. The scheme is based on intra-object sparsity. In the encoding phase the dominant Time Frequency (TF) instants of all active object signals are extracted and divided into several stages to form the multistage observation signals for transmission. In the decoding phase the preserved TF instants are recovered via Compressed Sensing (CS) technique, and further used for reconstructing the audio objects. The evaluations validated that the proposed encoding scheme can achieve scalable transmission while maintaining perceptual quality of each audio object.
Genetic Algorithm Based Clustering for Large-Scale Sensor Networks
Authors: Lin Hai , Kong Ruoshan , Liu Jiali 
Published: May 2018

Abstract
Despite the success of various clustering algorithms for Wireless Sensor Networks (WSNs), there are few works that consider the interference between clusters. Obviously, interference-free clustering makes the communication more efficient and achieves energy saving. In this paper we propose a new clustering method for large-scale sensor networks. With this method the network is partitioned into clusters. Intra-cluster communication in a cluster has no interference by its neighbor clusters. Moreover, the proposed clustering is based on a Genetic Algorithm (GA), which can achieve optimal performance in terms of the number of isolated nodes. This is demonstrated by the simulation analysis.

Authors: Hájek Matej , Decký Martin , Scherfel Walter 
Published: May 2018

Abstract
Principles of sustainable development create the need to develop new building materials. Foam concrete is a type of lightweight concrete that has many advantages compared to conventional building materials, for example low density and thermal insulation characteristics. With current development level, any negatively influencing material features are constantly eliminated as well. This paper is dealing with substitution of hydraulically bound mixtures by cement foam concrete Poroflow 17-5. The executed assessment is according to the methodology of assessing the existing asphalt pavements in Slovak Republic. The ex post calculation was used to estimate modulus range for Poroflow 17-5 based on the results of static load tests conducted using the Testing Experiment Equipment.
Systemic treatment of Krukenberg tumors
Authors: Kolak Agnieszka , Lozinski Michal , Mandziuk Slawomir 
Published: May 2018

Abstract
Of all ovarian tumors with distinct biological features, 10-25% are secondary ovarian tumors. Among the most common cancers that cause ovarian metastasis are breast cancer, colorectal cancer, endometrium, as well as gastric and lateral cancer. Krukenberg tumors remain asymptomatic until the tumor reaches a certain size, as in the case of primary ovarian cancer. Symptoms are non-specific: abdominal pain (42%), postmenopausal bleeding (18%), weight loss (6%) and an increasing abdominal girth (15%). Diagnostic procedures should include physical examination, basic blood and biochemistry tests, radiographic imaging and endoscopy. There are currently no uniform guidelines to be followed in order to treat this cancer. However, the survival rate of selected subgroups of patients may be enhanced by means of cytoreductive surgery (performable among patients with good general health condition), where the metastases are limited only to the ovaries, where the primary tumor is derived from the colorectal cancer, and where there is the absence or minimal residual disease. It is still controversial to use adjuvant chemotherapy following the metastasectomy of Krukenberg tumors. Although this type of treatment seems to provide a survival benefit, there are currently no randomized prospective trials available so as to confirm or deny. Future research should, therefore, be focused on the potentially synergistic effect of surgery and perioperative administration of cytotoxic therapies targeted at high response rates. Studies on new molecularly targeted drugs can also be beneficial.
