This paper presents a newly-compiled diachronic corpus of Australian English (AusBrown). With four sampling time points (1931, 1961, 1991 and 2006), Aus-Brown is designed to match the current suite of British and American ‘Brown-family’ corpora in both sampling year and design. We provide details of the composition and compilation of AusBrown, and explore the broader context of its ‘Brown-family background’ and of complementary Australian corpora. We also overview research based on the Australian corpora presented, including several AusBrown-based papers.

Grinding operations are one of the most commonly used preparation processes in many branches, for example in food, energy and chemical sectors. This paper focuses on the issues connected with design of technical objects in accordance with sustainable development assumptions. The aim of this study is to create methodology of sustainable design of grinding machine, including external influences involved in their operation, to increase safety, energy, economic and eco- efficiency. The problem formulated as a question: what techniques, equipment, methods, and ways should be used in design to obtain a new, better grinder structure? To resolve the problem, original methodology of sustainable design has been created.

The paper considers the use of the bootstrap method to improve the determination of confidence intervals identified by the DOE (design of experiment) procedure. Two different approaches have been used: one that is appropriate for factorial designs and the other one relevant to the methodology of the response surface. Both approaches were tested on the real experiment datasets and compared with the results obtained from the classical statistical expressions based on well-known asymptotic formulas derived from the t distribution.

Project management is general planning, coordination and inspection of the project, from the initial stage all the way to final phase, its purpose is an accomplishment of the accepted task and creation of the functional final effect, without exceeding established costs, time-frames and fulfillment of required standards of the quality. The present article was devoted to the issue of the project management in the construction sector in order to reduce the business risk. The study is based on literature examinations with an own methodological solution for project management in the construction industry. After introducing a set of definitions of the project and describing the concept of project management, a characterization of the project management in the construction industry and its effects in the economic space were described

Shade effect is a defect of the images very often invisible for human vision perception but may cause difficulties in proper image processing and object detection especially if the aim of the task is to proceed detection and quantitative analysis of the objects. There are several methods in image processing systems or presented in the literature, however some of them introduce unexpected changes in the images, what may interfere the final quantitative analysis. In order to solve this problem, authors proposed a new method for shade correction, which is based on simulation of the image background based on analytical methods which return pixel values representing smooth grey level changes. Comparison of the effects of correction by applying standard methods and the method proposed are presented.
A composite material is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. Modern composite materials are usually optimized to achieve a particular balance of properties for a given range of applications. Composites are commonly classified at two distinct levels. The first level of classification is usually made with respect to the matrix constituent. The major composite classes include organic – matrix composites (OMC's), metal – matrix composites (MMC's), and ceramic – matrix composites (CMC's). The OMC's is generally assumed to include two classes of composites: polymer – matrix composites (PMC's) and carbon – matrix composites (Peters, 1998). The composite material used in the work belongs to the PMC's and the composite is formed by the polymer matrix – rubber (sidewall mixture). As filler was used hard-magnetic strontium ferrite. Composite samples were prepared with different filler content (20%, 30%, 40%, 50%). Testing of polymer composites included: tensile test, elongation at break, hardness test and study of morphology.
The article presents a multi-aspect approach to the knowledge management system. Knowledge management focuses on the problem of creating and disposing of intellectual competence resources and practical skills, which are intangible assets of an enterprise. They concern different fields of science and empirical applications, and they are used to achieve a significant competitive advantage. In addition, knowledge management is focused on learning processes and improving the skills of the organization’s employees, systematizing and using knowledge in business practice. Therefore, effective use of knowledge management principles can contribute to increasing the effectiveness of the company’s operations and improving its competitive position.
The aim of this article is to present the concept of knowledge management through a critical analysis of domestic and foreign literature on issues related to knowledge processes, approaches to knowledge management and practices. The featured problem will be presented not only from the theoretical but also the practical side. Based on surveys conducted using the survey method, the most important benefits and barriers associated with introducing the concept of knowledge management or its elements in the enterprise will be identified.
The case of a career media participant turned media professional
This article discusses the relationship between nonprofessional media participation and the professional handling of participants. It expands on the case of “Karen”, who related her life-threatening illness and patient experience in a broad range of media before transitioning into professional communications work for a health organization that required her to recruit other patient-participants. The article contributes to research on media participation by focusing on the blurred boundaries between professionals and nonprofessionals. It describes how relationships between the two can be characterized by tensions and dilemmas that are closely tied to issues of status and control. Karen’s case is instructive in the particular light it sheds on such matters and on how control over the mediated telling of a life story is exercised.

In this article presented results of researching corrosion of steel bars in aggressive environment in time under loading. For researching were used special equipment. The experience and research works shown that steel bars in the crack cross-section area can be corrode. With increasing width of crack in re-bars and power of aggressive of environment increased the level of corrosion and decreased time of progress. The level of danger of corrosion in the crack in depend of specialty of steel bars. It is geometry parameters of steel bars and characteristic of corrosive behaviour. The general tendency of the influence of various defects on the strength of steels is widely studied experimentally and theoretically only for geometrically correct stress concentrators. For damages that are irregular in shape, such as corrosion ulcers, significantly less researching in each case must experiment to find their effect on the mechanical properties of steels. In this work the influence of simultaneous action of the aggressive environment and loading on strength of steel re-bars has been described.
