Symbiotic association between golden berry (Physalis peruviana) and arbuscular mycorrhizal fungi in heavy metal-contaminated soil
Authors: Hristozkova Marieta , Geneva Maria , Stancheva Ira , Iliev Ivan , Azcón-Aguilar Concepción 
Published: July 2017

AbstractPhysalis peruvianais one of the most promising tropical fruit plants because of its rapid growth, high yield, and nutritional quality. This study was designed to investigate plant development under heavy metal contamination (Cd, Pb) and responsiveness to arbuscular mycorrhizal fungi (AMF) colonization byRhizophagus clarumandClaroideoglomus claroideum. The antioxidant capacity, total lipid content and fatty acid profile in fruits, accumulation of Cd and Pb in different plant parts, plant dry biomass, and mycorrhizal colonization were determined. As a result of inoculation, a considerable reduction in Cd and Pb in the fruits was observed, compared with non-inoculated plants. The fruit number and dry weight increased in plants associated withC. claroideum.These plants also showed higher acid phosphatase activity, root protein accumulation and glomalin production. The type of antioxidant defense was AMF strain-dependent. Antioxidant activity and H2O2neutralization were enzymatic rather than non-enzymatic processes in the fruits ofC. claroideumplants compared with those forming an association withR. clarum. Mycorrhizal establishment changed the composition and concentration of fruits’ fatty acids. The ratio of unsaturated fatty acids was increased. With respect to the accumulation of bioactive compounds in golden berry the present findings are important for obtaining the optimum benefits of mycorrhizal association under unfavorable conditions.
Regular Mechanical Transformation of Rotations Into Translations: Part 1. Kinematic Analysis and Definition of the Basic Characteristics
Authors: Abadjieva Emilia , Abadjiev Valentin 
Published: July 2017

Abstract
The science that study the processes of motions transformation upon a preliminary defined law between non-coplanar axes (in general case) axes of rotations or axis of rotation and direction of rectilinear translation by three-link mechanisms, equipped with high kinematic joints, can be treated as an independent branch of Applied Mechanics. It deals with mechanical behaviour of these multibody systems in relation to the kinematic and geometric characteristics of the elements of the high kinematic joints, which form them. The object of study here is the process of regular transformation of rotation into translation. The developed mathematical model is subjected to the defined task for studying the sliding velocity vector function at the contact point from the surfaces elements of arbitrary high kinematic joints. The main kinematic characteristics of the studied type motions transformation (kinematic cylinders on level, kinematic relative helices (helical conoids) and kinematic pitch configurations) are defined on the bases of the realized analysis. These features expand the theoretical knowledge, which is the objective of the gearing theory. They also complement the system of kinematic and geometric primitives, that form the mathematical model for synthesis of spatial rack mechanisms.
Influence of Interface Gap on the Stress Behaviour of Smart Single Lap Joints Under Time Harmonic Load
Authors: Ivanova Jordanka , Valeva Varbinka 
Published: July 2017

AbstractAdhesive joints are frequently used in different composite structures due to their improved mechanical performance and better understanding of the failure mechanics. The application of such structures can be seen in aerospace and high technology components. The authors developed and applied modified shear lag analysis to investigate the hygrothermalpiezoelectric response of a smart single lap joint at environmental conditions (with/without an interface gap along the overlap zone) and under dynamic time harmonic mechanical and electric loads. The main key is the study of the appearance of possible delamination along the interface. As illustrative examples, the analytical closed form solution of the structure shear and the axial stresses response, as well as the interface debond length, including influence of mechanical, piezoelectric, thermal characteristics and frequencies is performed and discussed. All results are presented in figures. The comparison of the shear stress and electric fields for both cases of overlap zone (continuous or with a gap) is also shown in figures and discussed.

Rapid Design Optimization of Multi-Band Antennas by Means of Response Features
Authors: Kozieł Sławomir , Bekasiewicz Adrian 
Published: July 2017

AbstractThis work examines the reduced-cost design optimization of dual- and multi-band antennas. The primary challenge is independent yet simultaneous control of the antenna responses at two or more frequency bands. In order to handle this task, a feature-based optimization approach is adopted where the design objectives are formulated on the basis of the coordinates of so-called characteristic points (or response features) of the antenna response. Due to only slightly nonlinear dependence of the feature points on antenna geometry parameters, optimization can be attained at a low computational cost. Our approach is demonstrated using two antenna structures with the optimum designs obtained in just a few dozen of EM simulations of the respective structure.
Application of Improved Robust Kalman Filter in Data Fusion for PPP/INS Tightly Coupled Positioning System
Authors: Li Zengke , Yao Yifei , Wang Jian , Gao Jingxiang 
Published: July 2017

AbstractA robust Kalman filter improved with IGG (Institute of Geodesy and Geophysics) scheme is proposed and used to resist the harmful effect of gross error from GPS observation in PPP/INS (precise point positioning/inertial navigation system) tightly coupled positioning. A new robust filter factor is constructed as a three-section function to increase the computational efficiency based on the IGG principle. The results of simulation analysis show that the robust Kalman filter with IGG scheme is able to reduce the filter iteration number and increase efficiency. The effectiveness of new robust filter is demonstrated by a real experiment. The results support our conclusion that the improved robust Kalman filter with IGG scheme used in PPP/INS tightly coupled positioning is able to remove the ill effect of gross error in GPS pseudorange observation. It clearly illustrates that the improved robust Kalman filter is very effective, and all simulated gross errors added to GPS pseudorange observation are successfully detected and modified.
Preconditions for Emergence of Lithuanian Clusters: from Informal Cooperation to Its Legitimation
Authors: Grumadaitė Kristina , Jucevičius Giedrius 
Published: July 2017

Abstract
This paper reveals preconditions for the emergence of clusters as self-organisation based industrial systems in a context, in which cooperation traditions are insufficiently developed. These preconditions reflect the principles of the emergence of self-organising complex adaptive systems that are analysed in the complexity theory. Those principles are based on the initiation of non-equilibrium and its purposeful direction into the creation of a new order. This paper highlights the main external and internal tensions that influence informal or formal clustering of enterprises, while various change agents perform different roles making self-organising processes to occur.

Published: July 2017

Abstract
We use an institutional approach to analyze differences and similarities between competition policy regimes in Slovenia and Germany. We first indicate differences that exist in the implementation of EU competition law at the national level, given the unified framework of EU competition policy. In a next step, we discuss recent cases in both countries and indicate how historical developments and economic factors influence decision making and case law. We also discuss recent developments of the national competition policy regimes and indicate how the digital economy might shape competition policy in the future.
Changes in Responsibilities and Tasks of Universities in Regional Innovation Ecosystems
Authors: Birkner Zoltán , Máhr Tivadar , Berkes Nora Rodek 
Published: July 2017

Abstract
Innovation process research is changing. In addition to the former territorial approach (examining countries or regions), the description of innovation cooperation in local areas is becoming more and more accepted. Instead of the innovation ability of the traditional large enterprises, research has begun to study the role of small and medium-sized enterprises, non-governmental organizations, local governments, and educational institutions (especially universities), which foreshadows the development of a new innovation system. In 2015, we conducted a study focusing on the civil and corporate relations of a major university. We tried to determine the new directions based on the economic and social cooperation as well as to search for the practical implementation of the theoretical helixes in these interactions. We came to the conclusion that universities not only are determinative according to the triple helix model but also have a prominent role in the creation of new innovation ecosystems, particularly in a well-defined geographical area.
Economic Effects of Renewable Energy Technologies
Authors: Maradin Dario , Cerović Ljerka , Mjeda Trina 
Published: July 2017

AbstractRapid economic development has resulted in the more frequent use of renewable energy technologies. On the other hand, the production and use of renewables fosters the development of new technologies, creating many new opportunities for entrepreneurial-minded individuals and, consequently, the economy in general. Renewable energy technologies have a multiplier effect in spurring the economy and the development of not only the energy sector but also all the supporting activities related to such industry. The purpose of this research is to analyse both the positive and the negative economic effects of investing in various renewable technologies, as well as to confirm, by means of the energy-economy model, the benefit of such technologies in boosting the economy.
Electrical resistivity and spatial variation in agriculture terraces: statistical correlation between ert and flow direction algorithms
Authors: Fernandes J. , Bateira C. , Costa A. , Fonseca B. , Moura R. 
Published: July 2017

Abstract
The construction of earthen embankment terraces in the Douro Region raises a set of problems related to hydrological processes. The main objective of this study is the evaluation of the spatial variation of electrical resistivity in agriculture terraces at Douro valley (Portugal). To achieve this objective, two variables are analysed, the soil electrical resistivity and the flow direction algorithm. In a field survey we recorded 13 electrical resistivity profiles. The contributing area was calculated with the algorithms D∞ (Deterministic Infinity Flow) and MFD (Multiple Flow Direction) and the results are the base of the internal runoff modelling, both supported by the digital elevation model with a spatial resolution of 1m2. A correlation between the spatial variation of the soil electrical resistivity represented by the standard deviation of the electrical resistivity for each profile and the average value of the contributing area coincident with each profile was established. The electrical resistivity standard deviation seems to be moderately well correlated according to the D∞ algorithm at about 1m of depth, and it has a good correlation at 1,5m to 2m of depth with the MFD algorithm. Taken together, the results show a significant positive statistical correlation between the electrical resistivity standard deviation and the contributing areas (MFD and D∞) depending on the soil depth.
Process analysis transit of municipal waste. Part I - International provisions of law
Authors: Starkowski Dariusz , Bardziński Paweł 
Published: July 2017

Abstract
One of the crucial reasons of the system changes of waste management in our legal system in Poland was a need to implement solutions and mechanisms that are applied in the European Union. At the European Union law level, a Directive 2008/98/EC of the European Parliament and of the Council of 19 November 2008 on waste and repealing certain Directives constitutes a basic legal document described in this part of the article. The essential idea of the quoted directive is creating legal measures, promotion of eliminating waste production and treating it as a source instead. Achievement of these assumptions requires providing segregation at source and recycling of the main waste streams above all. It is necessary to encourage this action and support the reuse of products and waste utilization. Indicated international legal instruments are of primary importance for internal rules, which shall be constructed in a way that enables the achievement of goals determined by the EU law. Legal-organizational internal systems associated with the management of waste have undergone substantial changes from 2010. National legal provisions will be presented in the second part of the article.
Environmental and technological carrot safety conditions. Part I. Changes in the content of nitrates determined by the environment and processing

Published: July 2017

AbstractThe aim of the research was to define changes in the content of NO3¯ determined by the environment and processing in products from five cultivars of carrot, orange in colour. Besides this, in the research, the human intake of toxic compounds found in processed foods was also assayed. All the processed foods were produced at laboratory scale compliant with the applicable guidelines and norms. The content of nitrates in processed foods depended significantly on the genetic conditions of material and on the processing method. Of all the cultivars under study, ‘Karotan’ was least applicable to processing since, irrespective of the processing method, the lowest decrease in nitrates was reported for that cultivar. The consumption of processed foods from the cultivars of carrot studied is not hazardous to consumer health, since the value of the ADI in adult, Acceptable Daily Intake, is not exceeded.

Published: July 2017

Abstract
In the period of 2012-2013, a research was conducted to investigate the insects damaging the seeds of field elm (Ulmus minor Mill.). The aim of the research was to specify the damages to field elm seeds caused mainly by the brick (Agrochola circellaris) and to indicate the possible dependence between the number of damaged seeds by the caterpillars of this moth and stand density. The research was conducted in the areas of Cisów-Orłowiny Landscape Park (C-OLP) and Nida Landscape Park (NLP) in the Świętokrzyskie Province. In both parks, there were two test stands situated, each of which covered the material collected from the trees. The number of field elms ranged from four to six. Furthermore, a sample of 300 seeds were randomly collected from each tree. The elms in Cisów-Orłowiny Landscape Park were observed in full density stands (fully stocked stands); however, these trees in Nida Landscape Park were growing in loose density stands (under-stocked stands). In total, there were 12,000 seeds collected from 20 trees. The analysis of the collected research material demonstrated that 436 seeds from the field elms (Ulmus minor) were damaged by the brick (Agrochola circellaris). It constituted 3.6% of the total number of collected samples (Table 1). In the seed samples collected from the test stands in Cisów-Orłowiny Landscape Park, the damages caused by the caterpillars of the brick moth ranged between 0.8% and 2.9%. In the case of seed samples collected from Nida Landscape Park, the damages caused by the caterpillars of the brick moth were greater and ranged between 4.1% and 6.5%. The percentage of undamaged seeds ranged between 94.4% in Cisów-Orłowiny Landscape Park and 84.7% in Nida Landscape Park, which constituted, on an average, 89.5% for both parks. The 6.8% of the seeds were also damaged by other insects. The results of the research showed the dependence between the number of field elm seeds damaged by the brick Agrochola circellaris and the stand density (Table 2). The seeds collected from trees growing in the Nida Landscape Park in loose density stands (under-stocked stands) were twice as frequently damaged than those collected from the trees growing in Cisów-Orłowiny Landscape Park in full density stands. Also, the damages caused by other insects were greater among the seeds collected from trees growing in loose density stands than in full density stands (Table 1).

Abstract
Objective: The purpose of this study is to demonstrate the synchronous bilateral breast irradiation radiotherapy technique using a single isocenter. Materials and Methods: Six patients of synchronous bilateral breast were treated with single isocenter technique from February 2011 to June 2016. All the patients underwent a CT-simulation using appropriate positioning device. Target volumes and critical structures like heart, lung, esophagus, thyroid, etc., were delineated slice by slice in the CT data. An isocenter was placed above the sternum on the skin and both medial tangential and lateral tangential of the breast / chest wall were created using asymmetrical jaws to avoid the beam divergence through the lung and heart. The field weighting were adjusted manually to obtain a homogenous dose distribution. The planning objectives were to deliver uniform doses around the target and keep the doses to the organ at risk within the permissible limit. The beam energy of 6 MV or combination of 6 MV and 15 MV photons were used in the tangential fields according to the tangential separation. Boluses were used for all the mastectomy patients to increase the doses on the chest wall. In addition to that enhanced dynamic wedge and field in field technique were also used to obtain a homogenous distribution around the target volume and reduce the hot spots. The isocenter was just kept on the skin, such that the beam junctions will be overlapped only on the air just above the sternum. Acute toxicity during the treatment and late toxicity were recorded during the patient’s follow-up. Results: During the radiotherapy treatment follow-up there were no acute skin reactions in the field junctions, but one patient had grade 1 esophagitis and two patients had grade 2 skin reactions in the chest wall. With a median follow-up of 38.5 months (range: 8 - 49 months), no patients had a local recurrence, but one patients with triple negative disease had a distant metastases in brain and died after 28 months. Conclusions: We were able to successfully treat the synchronous bilateral breast using single isocenter radiotherapy while keeping the lung and heart doses within the acceptable dose limits. During the treatment follow-up there were no symptoms of acute skin reactions in the field junction.
Weighting alternative for water stable isotopes: Statical comparison between station- and firn/ice-records
Authors: Hatvani István Gábor , Kern Zoltán 
Published: July 2017

Abstract
It is generally accepted that ice cores archive amount-weighted water stable isotope signals. In order to achieve an improved understanding of the nature of water stable isotope signals stored in ice cores annual δ18O and δ2H averages (i.e. amount-weighted) were calculated for two Antarctic meteorological stations, Vernadsky and Hal­ley Bay, using monthly precipitation amount and monthly net accumulation as weights, respectively. These were then compared with the annual mean δ18O δ2H and records of the nearest available ice cores. In addition, at the stations, both arithmetic means (i.e. time-weighted) and amount-weighted (precipitation amount and net accumulation used as weights) annual air temperature averages were calculated and then compared to amount weighted annual mean δ18O and δ2H using correlation- and regression analyses. The main hypothesis was that amount weighted annual mean water isotope and temperature records from the stations would be able to replicate the annual water isotope signal stored in ice cores to a higher degree. Results showed that (i) amount weighting is incapable of ameliorating the signal replication between the stations and the ice cores, while arithmetic means gave the stronger linear relationships; (ii) post depositional processes may have a more determining effect on the isotopic composition of the firn than expected; and (iii) mean annual air temperature provided the closest match to ice core derived annual water isotope records. This latter conveys a similar message to that of recent findings, in as much as ambient temperature, via equilibrium isotope fractionation, is imprinted into the uppermost snow layer by vapor exchange even between precipitation events. Together, these observations imply that ice core stable water isotope records can be a more continuous archive of near-surface temperature changes than hitherto believed.
The community feeling versus anxiety, self-esteem and well-being – introductory research
Authors: Kałużna-Wielobób Alina 
Published: July 2017

Abstract
In accordance with the concept of A. Adler (1933/1986) - the community feeling is an individual characteristic which is relatively stable throughout life. It refers to an inner relationship of one person with other people: a feeling of unity with others or separation from others. People with high community feeling are motivated in their actions by striving towards the common good, whereas people with low community feeling intend to exhibit their superiority over others in their actions, which would allow them to compensate for their inner feeling of inferiority. On the basis of the Adler concept the following hypotheses were formulated: There is a negative connection between the community feeling and anxiety. The community feeling is positively connected with self-esteem and psychological well-being. A slight increase in the community feeling can be observed with age. The community feeling increases in the age of middle adulthood. 585 people between 20 to 65 years of age were examined. Methods: Community Feeling Questionnaire, State-Trait Anxiety Inventory, Rosenberg Self-Esteem Scale, Ryff Scales of Psychological Well-Being. The hypotheses assumed were verified.
