The generative propagation and quality of new male-sterile cauliflowers with the Ogu-INRA and Brassica nigra cytoplasm
Authors: Kamiński Piotr 
Published: June 2014

ABSTRACT
In the years of 2012-2013 male-sterile cauliflower genotypes with the Brassica nigra cytoplasm and their maintainers were tested with respect to their ability for generative propagation and the quality of agronomical traits in comparison to male-fertile inbreeds and sterile genotypes with the Ogu-INRA cytoplasm. The ability for the generative propagation for male-sterile genotypes with the B. nigra cytoplasm was diversified and lower than for the maintainer, fertile lines and lines with the Ogu-INRA cytoplasm.
Generative stalks of cauliflowers with the B. nigra cytoplasm usually had a higher number of buds and flowers in comparison to the fertile genotypes and to the sterile Ogu-INRA lines. The most desired commercial characteristics, such as circular shape, compactness of curd and intermediate or strong coverage by leaves, were noticed for sterile lines with the Ogu-INRA cytoplasm and their fertile complementary lines. Three experimental F1 hybrids showed good quality in comparison to commercial F1 cultivars.

Authors: Sopotlieva Desislava , Apostolova Iva 
Published: June 2014

Abstract
The geographic position of Bulgaria results in a variety of climatic and biogeographic influences on the country’s vegetation. We aim to describe the plant diversity of dry grasslands distributed in the transitional belt between the south-eastern European and Mediterranean biogeographic regions in SE Bulgaria, and to reveal if there are any obvious differences in soil properties, presence of life forms and chorotypes between syntaxa. The data set consists of 349 releves of vascular plants and bryophytes sampled in different semi-natural herbaceous vegetation types. By applying TWINSPAN, we classified 176 releves of dry grasslands to eight associations and one unranked community. One association and two subassociations are described here for the first time. Data on soil depth, soil moisture, soil pH, humus and total N content, numbers of different life forms and chorotypes were analysed statistically. The dry grasslands in SE Bulgaria were classified into different vegetation classes sharing the same territory: their communities present similarities in species composition and they have similar ratios of hemicryptophytes/therophytes and Euro-Asiatic/Mediterranean species. Dry grassland vegetation occupies mostly shallow and dry soils that vary slightly in pH, humus content and soil moisture between associations.

Authors: Sedighi Alireza 
Published: June 2014

Abstract
An efficient procedure for classification of transient phenomena in distribution systems is proposed in this paper. The proposed method has been applied to classify some transient phenomena such as inrush current, load switching, capacitor switching and single phase to ground fault. The new scheme is based on wavelet transform algorithm. All of the events for feature extraction and test are simulated using Electro Magnetic Transient Program (EMTP). Results show high accuracy of proposed method.

Published: June 2014

Abstract
Ultra-wideband (UWB) signals with a large bandwidth has some advantages like multipath immunity, low transmission power, good resolution for ranging and detecting geo locations, as well as it can resist to narrow-band interference. These signals are used for transmission in short distance with high throughput. In this paper, we have analyzed different modulation schemes for performance comparison in terms of BER with UWB Gaussian second derivative monopulse and wavelet-based monopulse. The simulation results demonstrate that wavelet-based monopulse provides better performance in comparison to the other two monopulses.
Length-Scale Effects and Material Models at Numerical Simulations of Nanoindentation of A Metallic Alloy
Authors: Nikolov N. , Avdjieva T. , Altaparmakov I. 
Published: June 2014

Abstract
Some specially designed metallic alloys crystallize during process of rapid quenching which aims their amorphization. Nevertheless, change in their mechanical properties could be seen compared to these obtained during conventional technological regimes of cooling. That attracts the attention in this elaboration. Full 3-D numerical simulations of nanoindentation process of two material models are performed. The models reflect equivalent elastic and different plastic material properties. The plastic behaviour of the first one is subjected to yield criterion of Dracker-Prager and this of the second one to yield criterion of Mises. The reported numerical results depending on the nanoindentation scale length of 1000 nanometers, suggest different adequacy of the two yield criteria to the data obtained experimentally with a Zr-Al-Cu-Ni-Mo alloy. It could be speculated that the different effects developed depending on the indenter travel of 1000 nanometers and taken into account in the two yield criteria stand behind this fact and determinate three structural levels of plastic deformation.
Recursive Differentiation Method for Boundary Value Problems: Application to Analysis of a Beam-Column on an Elastic Foundation
Authors: Taha Mohamed 
Published: June 2014

Abstract
In the present work, the recursive differentiation method (RDM) is introduced and implemented to obtain analytical solutions for differential equations governing different types of boundary value prob- lems (BVP). Then, the method is applied to investigate the static behaviour of a beam-column resting on a two parameter foundation subjected to different types of lateral loading. The analytical solutions obtained using RDM and Adomian decomposition method (ADM) are found similar but the RDM requires less mathematical effort. It is indicated that the RDM is reliable, straightforward and efficient for investigation of BVP in finite domains. Several examples are solved to describe the method and the obtained results reveal that the method is convenient for solving linear, nonlinear and higher order ordinary differential equations. However, it is indicated that, in the case of beam-columns resting on foundations, the beam-column may be buckled in a higher mode rather than a lower one, then the critical load in that case is that accompanies the higher mode. This result is very important to avoid static instability as it is widely common that the buckling load of the first buckling mode is always the smaller one, which is true only in the case of the beam-columns without foundations.

Authors: Niemczewska-Wójcik Magdalena , Mathia Thomas , Wójcik Artur 
Published: June 2014

Abstract
The quality of machined surfaces, resulting from the manufacturing process and conditioning their functionality, is determined by the surface geometric structure (SGS). There is a close relationship between surface properties, shape, qualitative imagining of the surface topography, technique and technology employed for machining purposes [1, 2]. If a given surface is to have practical applications in engineering, the correct technological process needs to be chosen.
In the paper, various techniques used for measuring the surface geometric structure were described. The results of the study, which were obtained from different measuring devices like Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and Optical Interferometer (WLI), were presented. Optical Microscopy (OM) was shown as a helpful device to analyse some aspects of surface topography. Each measuring technique provided different, yet complementary data on the topography of the machined surfaces. Owing to this, a full characterization of the geometric surface structure of the machined surfaces was enabled, including surface properties resulting from the applied technological process. Based on the measurements made, the characteristics of chosen devices (measurement techniques) were defined with an indication of how they can be applied to the analysis of the surface geometric structure (SGS). The devices which are considered to give the best view of examined surfaces and allow a thorough analysis of their irregularities were then indicated.

Abstract
While having been the object of numerous studies, the link between ERP implementation and SMEs performance still requires understanding. This paper documents the effect of investments in Enterprise Resource Planning (ERP) systems on a firm’s sales performance and profitability measure such as return on sales (ROS). The models are based on a sample of 240 during time of defined activities in the sales process realized during the each month by 40 knowledge workers in each of 5 Polish SMEs announcements of ERP implementations. Our analysis of the financial benefits of these implementations yields mixed results. Our results are encouraging that we find the business activity that can persistent evidence of sales performance associated with ERP investments. This should help alleviate the companies that some have expressed about the viability of ERP given the highly publicized implementation problems at some firms.

Published: June 2014

Abstract
Nowadays companies concern more about how to survive and extend their own business in future in their current marketplace. However, developing and prospering a region of the country is becoming more crucial question. Successful cooperation and partnership between different sectors of economy (for instance, between companies, public and academic sectors) leads to the flourishing and prosperity of the region and consequently of a country. European Commission established smart specialization platform, which is a strategic approach to economic development of a region. By defining and developing of vision, competitive advantages and strategic preferences, region will determine knowledge-based potential. The purpose of this paper is to assign and define the collaboration/relations existed, how strong these relations are and what the expectations are between 3 sectors of economy: public, academic and business. Area of carrying out this research is Ostrobothnia region, however, connections in other regions of Finland and internationally is also presented. There have been chosen 3 industrial peaks from Ostrobothnia region: Energy, Fur and Boat industrial peaks. Analysis is conducted by implementing two core methods: Sense & Respond (S&R) and Sustainable Competitive Advantage (SCA). The goal of this research is also to use S&R method so as to allocate efficiently resources, and to define competitive priorities in cooperation. The main results show that the most tight collaboration and partnership is observed between companies and companies in all around Finland and internationally. While concerning other relationships, companies expect to have tighter cooperation especially in Ostrobothnia and other regions of Finland.
Risk, control and self-identity: Young drunk drivers' experiences with driving under the influence of alcohol and drugs
Authors: Fynbo Lars 
Published: June 2014

Aim This article explores how young Danish drunk (and drug) drivers relate to the risk of driving under the influence (DUI). Design The study is based on qualitative interviews with 25 convicted drunk drivers who in 2010 participated in mandatory alcohol and traffic safety courses. The analysis follows Stephen Lyng's concept of “edgework”, focusing on volitional risk taking and its effect on the acting individual's self-identity. Results Drawing on the interviewees' accounts of being arrested for drunk driving, the analysis discusses three different categories of young drunk drivers. Those in the first category view a DUI arrest as a loss of control and a reminder of the risk of DUI. Those in the second present DUI as a reaction to what they perceive as untenable social demands. Those in the third see loss of control - such as causing a traffic accident - as the ultimate way of claiming control over their lives. Conclusion The study shows that young drunk drivers have different associations with DUI-related risks. The more constrained they feel in relation to society, the more likely it is that they will divorce negative experiences related to DUI such as being arrested or causing a traffic accident.
Population Potential as a Modulator of Land use Changes in Poland’S Metropolitan Areas
Authors: Werner Piotr , Korcelli Piotr , Kozubek Elżbieta 
Published: June 2014

Abstract
Land use is defined as a spatial distribution of individual forms of land cover patches, utilised or not utilised by humans within the framework of mutual and spatial relationships. It refers to the functional character of a given terrain, and is also identified with a socio-economic description of the land surface. Changes in land use can be interpreted as a complex and, to some extent, a random process. These assumptions serve as a point of departure in an attempt to evaluate spatial and temporal differences in land use changes in the metropolitan areas of Poland, using the entropy formula. The analysis focuses on population development as a factor that impacts upon land use change. The approach proposed here allows us to study land use dynamics in detail, with the help of cartographic visualisation.

Military Brownfields in the Czech Republic and the Potential for their Revitalisation, Focused on their Residential Function
Authors: Hercik Jan , Šimáček Petr , Szczyrba Zdeněk , Smolová Irena 
Published: June 2014

Abstract
One of the basic transformation processes of the period since 1989 has been that of demilitarisation. Among other things, one of its consequences is the emergence of abandoned military buildings and areas - so-called military brownfields. These kinds of brownfields have a large number of specific features to which their subsequent revitalisation must necessarily be adapted. Since a large number of these areas are situated within municipalities or are directly adjacent to them, it is essential for their revitalisation to be approached with great sensitivity. This contribution deals with chosen examples of Czech revitalised post-military areas with a special view to their residential function, which is presently their dominant functional use.
Delimitation of Nodal Regions Based on Transport Flows: Case Study of the Czech Republic
Authors: Kraft Stanislav , Marada Miroslav , Popjaková Dagmar 
Published: June 2014

Abstract
The delimitation of nodal regions belongs among the fundamental methods of studying spatial organisation. Nodal regions are defined as regions in which intraregional interactions are closed. With respect to the available information on spatial interactions, nodal regions are defined especially on the basis of data on commuting to work, migration flows, etc. Much less attention, however, has been paid to the theoretical and methodological questions of delimitation of nodal regions based on transport flows. In this case, transport flows that rank among the bearers of basic spatial interactions have high explanatory power, as they reflect not only commuting relations (commuting to work), but also service, business, recreational and other relations. The goal of this paper is to delimit nodal regions based on car transport flows in two regions in the Czech Republic and to evaluate their relevance in studying complex socio-economic relations within the regions.
Spatial Diversity of Biotechnology Centres in Germany
Authors: Dorocki Sławomir 
Published: June 2014

Abstract
Biotechnology is considered one of the key advanced technology sectors of the future. Its development is conditional on basic research in technologically advanced research institutes and appropriately qualified human resources. The optimum environment stimulating the development of biotechnology is that of production centres having joint industrial and R&D operations.
The growth of this sector in Germany began later than in the USA or other West European countries. But, thanks to the regional policy pursued by the state stimulating the development of biotechnology clusters, in a period of fifteen years or so, Germany has become the global leader. This paper presents the process of developing biotechnology centres in Germany as well as their spatial distribution, accompanied by their short description.

Authors: Kuczabski Aleksander , Michalski Tomasz 
Published: June 2014

Abstract
The post-communist transformation of Ukraine differs significantly from that of other countries of Central and Eastern Europe. First of all, Ukraine’s transition from totalitarianism to democracy has been long and still remains uncompleted. The process of the democratic transformation in Ukraine is non-linear and can be described by frequent changes in transformation phases. The ultimate result of the country’s transformation determines to a considerable extent the geopolitical stability in entire Central and Eastern Europe.
Composition results for strongly summing and dominated multilinear operators
Authors: Popa Dumitru 
Published: June 2014

AbstractIn this paper we prove some composition results for strongly summing and dominated operators. As an application we give necessary and sufficient conditions for a multilinear tensor product of multilinear operators to be strongly summing or dominated. Moreover, we show the failure of some possible n-linear versions of Grothendieck’s composition theorem in the case n ≥ 2 and give a new example of a 1-dominated, hence strongly 1-summing bilinear operator which is not weakly compact.

Darwin curves and galaxy arms
Authors: He Jin 
Published: June 2014

AbstractIn the natural world, there exists one kind of structure which is beyond the scope of human laboratorial experiment. It is the structure of galaxies which is usually composed of billions of stars. Spiral galaxies are flat disk-shaped. There are two types of spiral galaxies. The spiral galaxies with some bar-shaped pattern are called barred spirals, and the ones without the pattern are called ordinary spirals. Longer-wavelength galaxy images (infrared, for example) show that ordinary spiral galaxies are basically an axi-symmetric disk that is called exponential disk. For a planar distribution of matter, Jin He defined Darwin curves in the plane as such that the ratio of the matter densities at both sides of the curve is constant along the curve. Therefore, the arms of ordinary spiral galaxies are Darwin curves. Now an important question is that: Are the arms of barred spiral galaxies the Darwin curves too? Fortunately, Jin He designed a piece of Galaxy Anatomy graphic software. With the software, not only can people simulate the stellar density distribution of barred spiral galaxies but also can draw the Darwin curves of the simulated galaxy structure. This paper shows partial evidence that the arms of galaxy NGC 3275, 4548 and 5921 follow Darwin curves.
Scalar particles mass spectrum and localization on FRW branes embedded in a 5D de Sitter bulk
Authors: Dariescu Marina-Aura , Dariescu Ciprian 
Published: June 2014

AbstractIn this paper, we study the scalar fields evolving on a FRW brane embedded in a five-dimensional de Sitter bulk. The scale function and the warp factor, solutions of the Einstein equations, are employed in the five-dimensional Gordon equation describing the massive scalar field, whose wave function depends on the cosmic time and on the extra-dimension. We point out the existence of bounded states and find a minimum value of the effective four-dimensional mass. For the test (scalar) field envelope along the extra-dimension, we derive the corresponding Schrödinger-like equation which is formally that for the Pöschl-Teller potential. Accordingly, we have obtained the quantization law for the mass parameter of the tested scalar field.
