Well-posedness of evolution equations with time-dependent nonlinear mobility: A modified minimizing movement scheme
Authors: Zinsl Jonathan 
Published: December 2017

AbstractWe prove the existence of nonnegative weak solutions to a class of second- and fourth-order nonautonomous nonlinear evolution equations with an explicitly time-dependent mobility function posed on the whole space {{{\mathbb{R}}^{d}}}, for arbitrary {d\geq 1}. Exploiting a very formal gradient flow structure, the cornerstone of our proof is a modified version of the classical minimizing movement scheme for gradient flows. The mobility function is required to satisfy – at each time point separately – the conditions by which one can define a modified Wasserstein distance on the space of probability densities with finite second moment. The explicit dependency on the time variable is assumed to be at least of Lipschitz regularity. We also sketch possible extensions of our result to the case of bounded spatial domains and more general mobility functions.

Authors: Hutsol Taras , Firman Jurii , Komarnitsky Sergiy 
Published: December 2017

Abstract
The most time consuming and the least mechanized process of potato cultivation is its harvesting. Therefore, now, as never before, we have faced a problem concerning the improvement of the existing and construction of new devices for potato harvesting and their provision to the cultivation industry. It requires further development of theoretical, complex and extensive research on the phenomenon of separation of the potato stack, which will enable justification of optimal work modes of the existing separating devices and will be used for the synthesis of basically new, more advanced separators

Published: December 2017

Abstract
The objective of the research was assessment of the sowing quality of radish seeds with the sowing unit of “MAX PNEUAMTIC” S 156 pneumatic seeder. Tests were carried out on the original laboratory stand. They proved that at the assumed range of the working speed within 2.5 to 4.0 km·h−1 and rotations of the sowing disc between 23 and 37 rot·min−1, the most favourable results concerning precision of seeds spacing in a row were obtained at the speed between 2.5 and 3.0 km·h−1. The increase of the speed above 3.0 km·h−1 caused deterioration of the seeds sowing quality through statistically significant reduction of the single sowing participation and the increase of the empty sowings participation.

Published: December 2017

AbstractThe research was carried out in 2015-2016 at the Research Station Brody belonging to Poznan University of Life Sciences. The experiment was assumed with blocks randomized in four replications. The aim of the study was to determine the size and structure of energy inputs incurred on cover crops cultivation in different soil tillage systems. The cumulative energy consumption methodology was used to analyse the energy expenditure on field pea and white mustard seed. Based on the research, it was found that sowing field pea as a cover crop as compared to white mustard increased the cumulative energy input by 63.2%. Applied sowing technologies, regardless of cover crop species, reduced cumulative energy use by 22.5% (strip tillage) and direct sowing by 40.7% as compared to traditional tillage. The structure of energy input depended on the type of used cover crop species, which was based on the energy value of the seed used. The value of the energy efficiency index for growing both cover crop species increased with the simplification of the tillage.
Assessment of Particular Qualities of Carrot Availalbe in Selected Retailers in Krakow
Authors: Wrona Paulina , Pogoń Krystyna , Dróżdż Magdalena 
Published: December 2017

Abstract
The objective of the paper was assessment of the selected qualities of carrot from retailer's shops, organic and traditional food shops in Krakow. The following quality parameters of the fruit pulp were investigated: content of extract, sugars, polyphenols, nitrite, flavonoids, beta-carotene, colour, and antioxidant activity. The investigation shows that the content of nitrogen (V) in the samples of carrot from traditional cultivations was higher than in case of carrot from organic crops, and in case of a sample from traditional cultivation it exceeds the admissible norms. However, the research which was carried out provides no justification for the statement that the content of nitrate (III) depends on the production system of carrot. The research on the content of polyphenols, flavonoids and antioxidant activity of juice proved the increased antioxidant ability of carrot that was traditionally cultivated with reference to carrot cultivated organically. However, the differences were not statistically confirmed. Beta-carotene content in all samples was comparable regardless the cultivation system. Content of extracts, total carbohydrates and sucrose was significantly higher for carrot from traditional crops than for eco-carrot.
An iterative method for solving minimization, variational inequality and fixed point problems in reflexive Banach spaces
Authors: Jolaoso Lateef Olakunle , Ogbuisi Ferdinard Udochukwu , Mewomo Oluwatosin Temitope 
Published: December 2017

Abstract
In this paper, we propose an iterative algorithm for approximating a common fixed point of an infinite family of quasi-Bregman nonexpansive mappings which is also a solution to finite systems of convex minimization problems and variational inequality problems in real reflexive Banach spaces. We obtain a strong convergence result and give applications of our result to finding zeroes of an infinite family of Bregman inverse strongly monotone operators and a finite system of equilibrium problems in real reflexive Banach spaces. Our result extends many recent corresponding results in literature.
Application of fluorescent markers for homogeneity assessment of grain mixtures based on maize content
Authors: Matuszek Dominika B. , Wojtkiewicz Krystian 
Published: December 2017

Abstract
The paper presents test results for the assessment of the tracer content in a three-component (green peas, sorghum, maize) feed mixture that is based on the fluorescent method. The homogeneity of mixtures was determined on the basis of the maize content (as the key component), which was treated with fluorescent substance: tinopal, rhodamine B, uranine and eosin. The key components were wet-treated with fluorescent substances with different concentrations. Feed components were mixed in a vertical funnel-flow mixer. 10 samples were collected from each mixed batch. Samples were placed in a chamber equipped with UV light and, then, an image recorded as BMP file was generated. The image was analysed by means of the software programme Patan. On the basis of the analyses conducted, data on the maize content marked with a fluorescent marker were obtained. Additionally, the content of the key component was determined in a conventional manner – using an analytical scale. Results indicate the possibility of using this method for homogeneity assessment of the three-component grain mixture. From these tests, fluorescent substances that can be applied in the case of maize as a key component, together with their minimum concentrations, were identified: tinopal 0.3%, rhodamine B 0.001%.
Rhetorical questions or rhetorical uses of questions?
Authors: Špago Džemal 
Published: December 2017

Abstract
This paper aims to explore whether some rhetorical questions contain certain linguistic elements or forms which would differentiate them from answer-eliciting and action-eliciting questions, and thereby hint at their rhetorical nature even outside the context. Namely, despite the fact that the same questions can be rhetorical in one context, and answer-eliciting in another, some of them are more likely to be associated with rhetorical or non-rhetorical use. The analysis is based on extensive data (over 1200 examples of rhetorical questions taken from 30 plays by two British and two American writers), and the results are expected to give an insight into whether we can talk about rhetorical questions or just a rhetorical use of questions.
Hans Lassen Martensen’s “The Present Religious Crisis”
Authors: Stewart Jon 
Published: December 2017

AbstractThis article provides an English translation of Hans Lassen Martensen’s “The Present Religious Crisis” from 1842. In this work Martensen outlines two important trends that were much discussed at the time. The first part of his article is dedicated to the Anabaptist movement in Denmark, which was in open conflict with the Danish State Church about the question of infant baptism. In the second part, Martensen treats the work of the left Hegelian David Friedrich Strauss and his followers, who regarded the gospel accounts of the life of Jesus as, by and large, myths. Although polar opposites, these two movements are, for Martensen, symptoms of the religious confusion of the day. Martensen attempts to defend the Danish State Church in the face of these criticisms. Kierkegaard seems to refer to Martensen’s article in his “Public Confession,” where he refers to the rise of sects in Denmark and makes explicit reference to both the Anabaptists and the Straussians. Like Martensen, he is at pains to distance himself from Strauss and his followers. Martensen’s article also represents a landmark in the history of the Danish Hegel reception since it signals the alarm about the new Straussian trend.

Finger or Stylus: Their Impact on the Performance of On-line Signature Verification Systems
Authors: Antal Margit , Bandi András 
Published: December 2017

Abstract
The widespread use of smartphones and the ability of these devices to digitize signatures have made it possible to sign electronic documents in this way. In this paper we compared two on-line signature databases in terms of verification performance: the MCYT containing signatures drawn by stylus pen, and MOBISIG containing finger drawn signatures. Performance evaluations were performed using both local and global systems. In the case of global systems, we evaluated the performance of a novel information theory features set. Little improvement was achieved by this feature set. There were large differences between the two databases in terms of performance. Finger drawn signatures collected by mobile device were proved inferior to signatures collected by digitizing tablet and its stylus.
Hybrid modeling and model based control of the four tank process
Authors: Kardos Tamás , Kutasi Dénes Nimród 
Published: December 2017

Abstract
Hybrid systems contain both continuous dynamics and discrete elements, where discrete transitions happen between different continuous operating modes as a consequence of certain events. The notion of modeling these types of systems is discussed in regard to the four tank process, which has hybrid and nonlinear characteristics. This paper describes the modeling of this system in Simscape software and a hybrid model is created as well, with a hybrid controller being built around it that includes finite-state automata and PI controller. Simulations implemented in Matlab Simulink software prove the viability and correctitude of the method presented.
Computing Algorithm for the Gear Tooth Space Points Cloud Envelope Generated by the Mixed Cad Method
Authors: Tolvaly-Rosca Ferenc , Forgó Zoltán 
Published: December 2017

Abstract
The task of the mixed pure CAD generating method developed by the authors consists in finding only the points situated on the gear tooth surface. The use of the mixed CAD gear generating method results in a very large and particular type of Points Cloud: This contains points situated both in the tooth space, and on the tooth surface. The existing filtering programs and methods, as it was presented in previous papers, cannot deal with these particular point sets. The development of the named particular generating method claims an algorithm and a computer software which can find the envelope of the Points Cloud. This papers presents an Alpha Shape algorithm based filtering algorithm, adapted and developed to be used together with the mixed CAD generating software.

Broadband spectroscopy for characterization of tissue-like phantom optical properties
Authors: Shahin Ali , Bachir Wesam 
Published: December 2017

Abstract
Optical phantoms are widely used for evaluating the performance of biomedical optical modalities, and hence, absorbing and scattering materials are required for the construction of optical phantoms. Towards that aim, new readily available and inexpensive black Ink (Parker) as a simulating absorber as well as Intralipid 20% as a simulating scatterer are thoroughly investigated. Broadband Transmittance and Diffuse reflectance spectroscopic measurements were performed in the visible range 400 – 700 nm. Optical properties of the phantom materials are determined. Analytical expressions for absorption and scattering coefficient related to the concentrations and wavelength of the Parker ink and Intralipid are also presented and discussed. The results show nonlinear trend in the absorption coefficient of Parker ink over the examined visible spectral range. Furthermore, Intralipid scattering coefficient variation across the mentioned spectral range shows a tissue-like scattering trend. The findings demonstrate the capability of the broadband transmission and diffuse reflectance for characterizing tissue-like phantom materials in the examined spectral range.

Authors: Lichańska E. , Kulecki P. , Pańcikiewicz K. 
Published: December 2017

Abstract
The aim of the study was to evaluate the effect of chemical composition on the structure and mechanical properties of Mn-Ni-Mo and Ni-Mo-Cu PM steels. Pre-alloyed powder Astaloy 85Mo, diffusion alloyed powders Distaloy AQ and Distaloy AB produced by Höganäs, low carbon ferromanganese, carbonyl nickel powder T255 with three-dimensional filamentary structure and graphite CU-F have been used as the basic powders. Three mixtures with compositions of Fe-1%Mn-(0.5/1.75)%Ni-(0.5/0.85)%Mo-0.8%C and Fe-1.75%Ni-0.5%Mo-1.5%Cu-0.8%C were prepared in a Turbula mixer. Green compacts were single pressed in a steel die at 660 MPa according to PN-EN ISO 2740 standard. Sinterhardening was carried out at 1250°C in a mixture of 95% N2+5% H2 for 60 minutes. Mechanical tests (tensile, bend, hardness) and microstructural investigations were performed. Additionally, XRD and EDS analysis, fractographic investigations were carried out. The microstructures of steels investigated were mainly bainitic or bainitic-martensitic. Addition 1% Mn to Distaloy AQ based steel caused increase of tensile properties (YS from 422 to 489 MPa, UTS from 522 to 638 MPa, TRS from 901 to 1096 MPa) and decrease of plasticity (elongation from 3.65 to 2.84%).
Food supply (Orthoptera, Mantodea, Rodentia and Eulipotyphla) and food preferences of the red-footed falcon (Falco vespertinus) in Slovakia
Authors: Krištín Anton , Tulis Filip , Klimant Peter , Bacsa Kristián , Ambros Michal 
Published: December 2017

Abstract
Food supply in the nesting territories of species has a key role to the species diet composition and their breeding success. Red-footed falcon (Falco vespertinus) preys predominantly on larger insect species with a supplementary portion of smaller vertebrates. In the breeding periods 2014 and 2016 their food supply, focusing on Orthoptera, Mantodea, Rodentia and Eulipotyphla, was analysed at five historical nesting sites of the species in Slovakia. Preference for these prey groups in the diet was also studied at the last active nesting site in this country. Overall we recorded 45 Orthoptera species (of which 23 species are known as the food of the red-footed falcon), one species of Mantodea, 10 species of Rodentia (of which 2 species are known as the food of the red-footed falcon) and 5 species of the Eulipotyphla order in the food supply. With regard to the availability of the falcons' preferred food, in both years the most suitable was the Tvrdošovce site, which continuously showed the greatest range and abundance of particular species. In the interannual comparison the insects showed lower variability in abundance than the small mammals. In 2014 the growth of the common vole (Microtus arvalis) population culminated and with the exception of a single site (Bodza) a slump in abundance was recorded in 2016. In comparing the diet composition with the food supply at the last Slovak breeding site Rusovce (Special Protection Area Sysľovské polia), we recorded significant preference for grasshopper Caliptamus italicus (in 2014), common vole (in 2016) and cricket Tettigonia viridissima (in both years) in the falcons' diet. They did not prey on the Apodemus sylvaticus species belonging among the abundant small mammal species in that locality. Conservation measures in the agricultural landscape are discussed in relation to homogeneous red-footed falcon breeding territories.
Foraging opportunism and feeding frequency in the red-footed falcon (Falco vespertinus) in Slovakia: case study from 2017
Authors: Chavko Jozef , Krištín Anton 
Published: December 2017

AbstractForaging opportunism and feeding frequency are less studied parameters of behaviour in insectivorous falcons, many of which are endangered bird species. In this short study, prey composition and feeding frequency of red-footed falcon(Falco vespertinus) nestlings were studied using the method of camera recordings during seven days in July 2017 in southwestern Slovakia. Camera recording analyses of 2–3 chicks (14–26 days old) in three nests revealed a significant preference for insects (97%, n = 305 prey items), of which the Italian locust (Calliptamus italicus) was highly predominant (54%). We also found very high average chick feeding frequency (9.9 feedings per hour, n = 29 hours 22 min of regular observations), whereby the females fed their young ones more frequently (64.9%, n = 305 feedings) than the males (35.1%). Analyses of food composition in adverse weather conditions showed that unfavourable weather had a negative effect on chick feeding frequency, and in rainy weather the males fed significantly less than the females.
