Published: October 2020

Abstract
This article focuses on the analysis of mechanical properties of knitted barrier meshes and refers to general problems related to safety engineering. The conducted analysis of the effectiveness of absorbing impact energy by textile barriers, which positively affect the human body, clearly indicates the possibility of applying them in the field of road engineering as a new generation of road barriers. The characteristic features of the new generation of barriers are their openwork multiaxial structure based on various geometric shapes of the a-jour structure. Twenty models of barrier meshes with a-jour structure in the shape of tetragons (squares and diamonds), triangles, regular polygons (hexagons, octagons, and dodecagons), and circles were designed. Simulation research that aimed to optimize the structure of knitted openwork meshes to obtain minimum reduced stresses in strings, knots, and arms of the mesh was performed. The preferred solution is the four-axial eight-thread mesh with square-shaped a-jour structure with stress equal to Δб = 0.43 GPa/kg and the mesh with thickened diamond-shaped a-jour geometry with stress equal to Δб = 0.53 GPa/kg. Low stress values were also recorded for a four-axial six-thread mesh with square a-jour structure, for which Δб = 0.66 GPa/kg. The analyzed mesh models were implemented in the form of dozen designs of stitch constructions based on warp-knitting technology.

Zusammenfassung
Die Korn- und Stroherträge, der Energie-Input (Kraftstoff, Mineraldünger, Pflanzenschutzmittel, Maschinen) und die Kennzahlen zur Energieeffizienz (Energie-Output, Netto-Energie-Output, Energieintensität, Energienutzungseffizienz) in Abhängigkeit der mineralischen Stickstoffdüngermenge (0 kg, 60 kg, 120 kg und 180 kg N ha−1) und der Düngerstrategie (unterschiedliche Mineraldüngerformen und Gabenteilungen) wurden auf zwei Standorten im Marchfeld (Engelhartstetten und Groß-Enzersdorf) auf Basis von zwei zweijährigen Feldversuchen analysiert. Dabei sollte die Frage beantwortet werden, welche mineralische N-Düngung (N-Form, N-Menge und Splittung der N-Menge) die höchste Energieeffizienz aufweist. Mit zunehmender mineralischer N-Menge (60 kg, 120 kg bzw. 180 kg N ha−1) nahm der energetische Anteil des Mineraldüngers am Gesamtenergie-Input um 24 %, 38 % bzw. 48 % zu. Durch das Gesetz des abnehmenden Ertragszuwachses wurde in Engelhartstetten bei einer N-Düngermenge von 180 kg N ha−1 eine signifikant verringerte Energieeffizienz im Vergleich zu 60 kg N ha−1 und 120 kg N ha−1 festgestellt. Eine Aufteilung der N-Düngermenge auf drei Gaben erhöhte den Kraftstoffverbrauch um 4 % gegenüber einer einmaligen Applikation der gesamten Düngermenge. Die Kennzahlen der Energieeffizienz wurden durch die Gabenteilung kaum beeinflusst. Die N-Düngung mit Kalkammonsalpeter war energieeffizienter als die Harnstoffdüngung (rein, stabilisiert, eingearbeitet). Die Energieeffizienzanalyse kann somit einen wertvollen Beitrag leisten, um pflanzenbauliche Maßnahmen hinsichtlich ihren Umweltauswirkungen zu bewerten.
Conversion of agricultural soils in Austria—a case study for a community in Upper Austria

Published: October 2020

Summary
We have analyzed the loss of agricultural land in a case study of the community Eggelsberg in the Innviertel in Upper Austria. The trigger for the project was the attribution of Austria as Europe’s leader in soil sealing. We compared the results of the Austrian agricultural soil survey of the 1970s with the actual land use and quantified the land use change. Within half a century, 15% of the agricultural area was converted to settlement area or to other forms of infrastructure. According to the original soil assessment, 96 ha of high-quality cropland, 1,220 ha of medium-quality cropland, 121 ha of low-quality cropland, and 409 ha of grassland were converted. The forest cover remained stable. The highest share of soil sealing was owed to the expansion of the settlement area and the construction of a successful enterprise. Minor contributions were expansions of farm buildings. The loss of agricultural land was reasonable and reflected the needs of the local population. A special protection status because of the future relevance of the agricultural land was not communicated to land managers and is not reflected in the market prices of agricultural products. The relevance of the agricultural land beyond the regional level is not fully recognized.

Published: October 2020

Abstract
The research aimed to identify promising areas and outline problems associated with the transition of Ukrainian industrial enterprises towards advanced innovative development based on information and knowledge and to formulate recommendations for improving the knowledge management and commercialisation at these enterprises. The study used several methods for analysis, including a literature review; system, structural and statistical analyses; SWOT analysis; the inference method; and interpretation. The research efforts resulted in systemised major sources of knowledge in an enterprise and types of their utilisation. The performed analysis found the key ways to obtain and commercialise knowledge used by Ukrainian industrial enterprises. The results were compared with data of the EU countries. The analysis produced strengths and weaknesses of the existing knowledge management system used in Ukrainian enterprises. Strengths: growth in the number of enterprises producing new knowledge and implementing marketing and organisational innovations; intensified patent activity; and a rational structure of innovation-active enterprises by their size. Weaknesses: the new knowledge structure does not meet the needs of enterprises; an insignificant and unstable share of innovation-active enterprises in the total number of firms; and insignificant sales volumes of patents. The research revealed that Ukrainian enterprises had the potential ability to produce and commercialise new knowledge effectively and to use it as the basis to form, strengthen and implement relative competitive advantages, which would contribute to the innovative growth of the Ukrainian economy as a whole. Recommendations were designed for the formation of prerequisites necessary to improve the efficiency of knowledge management in the context of conditions required for the innovative development of domestic enterprises. The obtained results can be used as an information base for evaluating the system of knowledge production and commercialisation at Ukrainian enterprises to enhance the management and identify promising areas for innovative development.
Marketing and branding-oriented goals for the development of Functional Urban Areas: evidence from Poland
Authors: Matwiejczyk Anna , Glińska Ewa , Barkun Yauheniya 
Published: October 2020

Abstract
The European Union currently uses Functional Urban Areas (FUAs) as basic units for planning local development activities under its financial support. An important issue in terms of managing such areas is branding. FUAs are made of at least several territorial units (covering a dense urban area and a functionally related urbanised zone). Such composition poses a particular challenge in terms of developing a brand that covers all of the units. Therefore, it is essential to select the core around which the target image will be created. This publication aims to identify marketing and branding goals for the development of FUAs and determine activities facilitating the achievement of these goals by entities that manage the functional areas. The research method used in the article was a content analysis of documents outlined as Strategies for Integrated Territorial Investments developed for FUAs in Poland. The authors of the article undertook preliminary exploratory research. The obtained results show that most of the marketing and branding goals for the development of FUAs correspond with the objectives specific to city marketing and branding. Moreover, “integration” and “strengthening the metropolitan area function” were recognised as goals specific to FUAs.
Servitization of public service processes with a simulation modelling approach
Authors: Buics László , Eisingerné Balassa Boglárka 
Published: October 2020

Abstract
This article aims to examine how the theory of co-production can be connected with servitization and digitalisation and used together for the public service development with the help of discrete-event simulation modelling to highlight time-related deficiencies of a complex public service process, which is most commonly used by patchwork families. Data was taken from the Guardianship Office in Győr (Hungary), based on which in-depth interviews were conducted. Based on the legal background and the interviews, the authors of the article created the process model of the contacting procedure. Based on the model, discrete-event simulation was used to identify the process elements for potential improvement through servitization. Discrete-event simulation showed the insufficiency of national regulation regarding the whole process and weaknesses of the contacting procedures in terms of quality and success. Basic reasons were found for the dissatisfaction expressed by participants of the procedures (administrators and customers). The increasing customer demand for high quality and efficient public services and failures in the New Public Management (NPM) in Eastern European countries require other approaches to advance. The paper connects the theory of co-production and servitization in a public service context and demonstrates how a complex public service can be examined with this approach to find possible improvements. The government must change the process regulation considering the number of the cases, the workload of administrators and family types (divorced or patchwork). The emphasis should be placed on the training and experience of administrators.
Farm-heterogeneity and persistent and transient productive efficiencies in Ethiopia’s smallholder cereal farming
Authors: Berisso Oumer , Heshmati Almas 
Published: October 2020

Abstract
This paper does an empirical comparison of time-invariant and time-varying technical inefficiency measures obtained from an econometric estimation of different panel data stochastic production frontier models. It estimates four panel data specifications of frontier models widely used in empirical applications using a panel dataset from the Ethiopian cereal farming sector. The empirical results show that estimates of both the magnitude and the individual farms’ rankings of persistent and transient productive efficiencies differ considerably across models and based on their agro-ecological zones location. The results further show that the cereal growing farms experience much more transient inefficiency as compared to persistent inefficiency.

Published: October 2020

AbstractTo improve the engine efficiency by increasing the gas temperature, multi-layer cooling passages are applied in new designs of gas turbine blades. As a result, traditional non-destructive methods, which have been applied so far in the production control, became insufficient. The aim of this manuscript is to develop an inspection method for cooling passages of turbine blades, which would be helpful in detecting manufacturing defects of blades and their operational failures. GE v/tome/x/m 300 was applied to conduct dimensional control and check the interior of two types of turbine blades from turboshaft engines. The procedure for selecting X-ray parameters was suggested. The thickness of walls in the selected cross-section was measured with the accuracy of 0.01 mm, and the selected manufacturing defects of cooling passages were identified.

Investigation and sequence analysis of avian polyomavirus and psittacine beak and feather disease virus from companion birds in eastern Turkey
Authors: Adiguzel Mehmet Cemal , Timurkan Mehmet Ozkan , Cengiz Seyda 
Published: October 2020

Abstract

Introduction
Avian polyomavirus (APV) and psittacine beak and feather disease virus (PBFDV) induce contagious and persistent diseases that affect the beaks, feathers, and immune systems of companion birds. APV causes hepatitis, ascites, hydropericardium, depression, feather disorders, abdominal distension, and potentially death. PBFDV can induce progressive beak deformity, feather dystrophy, and plumage loss. We conducted the first prevalence survey of both APV and PBFDV infections in companion birds in eastern Turkey.

Material and Methods
A total of 113 fresh dropping samples from apparently healthy companion birds were collected in a random selection. The dropping samples were analysed for PBFDV and APV by PCR. Positive samples were sequenced with the Sanger method. The sequence was confirmed through alignment and the phylogenetic tree generated through the maximum likelihood method computationally.

Results
PBFDV and APV were detected in a respective 48.7% and 23.0% of samples. Coinfection was found in 12.4% of the samples, these all being from budgerigars (Melopsittacus undulatus). APV and PBFDV were detected in budgerigar and cockatiel (Nymphicus hollandicus) samples.

Conclusion
This report provides a foundation for future studies on the influence of these viruses on the health of companion birds. These high positive rates for both pathogens emphasise that healthy M. undulatus and N. hollandicus in eastern Turkey may be prone to the emergence and spread of APV and PBFDV with subclinical potential.
