    Opis:
    Desagrarization is an ambiguous, multifaceted notion and at the same time difficult to define. As a research subject it concerns mainly agriculture and is generally defined as the process of reducing the contribution of agriculture to the Gross Domestic Product. In terms of spatial changes caused by desagrarization, it is the reduction of agricultural land, increase in fallow land and woodiness, and uncontrolled landscape changes. The article seeks to present the spatial effects of the desagrarization process in the Polish rural areas. The results of the research were achieved by adopting the Shift-Share Analysis. The study confirmed that desagrarization manifests itself in changes both historical and global in character and the state interventionism and Common Agricultural Policy are limited to reducing in time its spatial and economic negative effects.

    Opis:
    The occurrence of stem-base diseases in two cultivars of winter wheat were evaluated in a 3-year experiment, using two agrotechnology levels. The two cultivars evaluated were durum wheat of the Komnata cultivar and common wheat of the Ostka Strzelecka cultivar. The highest intensity was noted in the occurrence of two diseases of the complex, i.e. Fusarium foot rot and eyespot. The examined cultivars were characterized by a similar susceptibility to these diseases. There was an observed difference - a slightly higher susceptibility by the Komnata as opposed to the Ostka Strzelecka cultivar - but it was not significant statistically. Significant differentiation in infestation was noted for other experimental factors like cultivation season and the agrotechnology level. Intensification of the occurrence of both stem-base diseases in the experimental seasons did not affect the mean amount and quality of the yield obtained in the experiment.

    Opis:
    The last few years have seen a very dynamic development of the Internet worldwide. This is related to the rapid growth of the amount of information stored in its resources. The vast amount of data, impossible to be analyzed by man, is the reason why finding and selecting valuable information from a large number of results returned by search engines has recently become the task very difficult. Another problem is the low quality of the data contained in a large part of the results returned by search engines. This situation poses serious problems if one searches for detailed information related to the specific area of industry or science. In addition, the lack of effective solutions, allowing for continuous monitoring of WEB in terms of the search for emerging information while maintaining the high quality of the returned results, only aggravates this situation. Due to this state of affairs, a solution highly welcome would be a system allowing for continuous monitoring of the WEB and searching for valuable information from the selected Internet resources. This paper describes a concept of such a system along with its initial implementation and application to search for information in the foundry industry. The results of a prototype implementation of this system were presented, and plans for its further development and adaptation to other sectors of the industry were outlined.

    Opis:
    A significant part of the knowledge used in the production processes is represented with natural language. Yet, the use of that knowledge in computer-assisted decision-making requires the application of appropriate formal and development tools. An interesting possibility is created by the use of an ontology that is understandable both for humans and for the computer. This paper presents a proposal for structuring the information about the foundry processes, based on the definition of ontology adapted to the physical structure of the ongoing technological operations that make up the process of producing castings.

    Opis:
    Access to up-to-date information on technology, innovation, source publications, and the materials and services offered in a particular industry is very important for both industrial plants and departmental research centres. It should be noted that obtaining such information using publicly available search engines such as Google, Yahoo!, Bing, Bindu (mainly used in China) is only apparently easy because, due to their versatility, they deliver results with great redundancy. This leads to the need to analyze large data sets by linguistic methods or "manually", which is very tedious and time consuming. In this situation, it was considered reasonable to undertake studies aimed at acquiring relatively simple IT tools, i.e. crawlers, which allow their users to selectively search for information in a particular problem area, which in this particular case is casting. The intention of this work was to collect and analyze the experimental material that would allow describing the characteristics of the above solutions from the point of view of the range of their application, the quality of the results achieved, and possible limitations and preferences taking into account user needs.

    Opis:
    Work was done as a part of the project " New generation haulage system of highly productive longwall systems" aiming to develop and implement a new longwall shearer system called KOMTRACK. The widely used EICOTRACK feed system developed forty years ago is not adapted to modern longwall shearers' power. Within the project, an innovative, flexible feed system with a modular structure was created with the possibility of continuous adjustment to the carbon wall's unevenness. Newly-developed three cast steels variants have been initially selected to fabricate this system's elements. The material's final selection was realized based on the tensile tests, Charpy impact tests, Brinell hardness surveys, and wear resistance measurements. Results analysis allowed to select cast steel marked as "2", which fulfilled all requirements and was used in further casting trials.

    Opis:
    The aim of this work was to propose a methodology supporting the task of collecting the comparative data on studies of the mechanical properties of ADI. Collecting of research data is an important step in the process of finding the optimum design solutions for newly made products - experimental data allow us properly calibrate the manufacturing process of ADI to let the final product achieve the required properties. Parameters of the ADI production process, i.e. the time and temperature of austenitising and austempering, as well as the alloying elements added to ductile iron affect the ADI properties. The design process can use research data collected, among others, from the Web. As stated in the article, the process of data acquisition can be supported by semantic technologies, including ontologies which are descriptive logic formalism.

    Opis:
    This article presents the research results on impact of the method of polycrystalline graphene layers separation from the growth substrate on the obtained carbon material quality. The studies were carried out on graphene sheets obtained by metallurgical method on a liquid metal substrate (HSMG® graphene). The graphene was separated using chemical etching method or the electrochemical delamination method, by separating by means of electrolysis. During electrolysis, hydrogen is emitted on a graphene-covered of cathode (metal growth substrate) as a result of the voltage applied. The graphene layer breaks away from metallic substrate by gas accumulation between them. The results from these separation processes were evaluated by means of different tools, such as SEM, TEM and AFM microscopy as well as Raman Spectroscopy. In summary, the majority of analyses indicate that the graphene obtained as a result of hydrogen delamination possesses higher purity, smaller size and number of defects, its surface is smooth and less developed after the transfer process to the target substrate.

    Opis:
    The article presents the results of studies on the efficacy of water desalination (i.e. Elimination of NaCl ions from the solution) using graphene-polyamide composite membranes. The membranę used for filtration consists of a monolayer of polycrystalline graphene on a porous polyamide carrier support (nylon 66). The degree of desalination for an aqueous NaCl solution percolated through the membrane was 18%. In the future this type of membrane may replace the currently used reverse osmosis membranes.
