The results of the study regarding utilization of the waste gypsum formed as a by-product during the production of the magnesium sulphate from dolomite have been presented. The use of this waste have been proposed for the production of granulated multi-component fertilizers containing 25% N; 8% S; 14% CaO and 3.5% MgO. In the process of fertilizer production, the urea which will be bounded with the calcium and magnesium sulphate from the waste in the form of adducts of CaSO4 . 4CO(NH2)2 and MgSO4 . CO(NH2)2 . 3H2O will be the source of nitrogen in the fertilizer. It has been stated on the basis of the laboratory tests that the fertilizer with the assumed composition can be obtained by means of granulation of the raw material pulp, along with the dried and ground product return. The possibility of the production of the fertilizer with good physical properties according to the assumed concept has been confirmed in the pilot scale.

The aim of the article is to present the essence of the adaptation of common SPC solutions appropriate for mass and batch production, to the conditions of piece and small lot production on the example of the selected production process. The article presents the possibility of using Shewhart control charts in improving piece and small lot production processes. The principles of data collection and transformation, to be useful to prepare charts, have been pointed out. Moreover, determination of capability indices for piece and small lot production has been shown. The proposed solution of using statistical process control tools in the analyzed company enables the board a fair assessment of the processes from the point of view of quality assurance, and thus reduce the cost of poor quality and well targeted improvement actions.

Time is a very important factor in the architectural creation of structure, form, and utility of flats and buildings in human settlements. The impact of the age of inhabitants stimulates the needs and arrangement of these flats. The other question in this case is the relation between the flexibility of a building and its heritage. The aspect of the form in housing is also very interesting: flexibility, adaptation and external appearance (elevation) of these buildings. The method of the paper is based on case studies, in situ inquiry (city walk: photo documentation, interviews, materials analysis) and theoretical research (literature insight). In this paper the authors will present the state of actual knowledge in this field in Europe. The following case studies will be shown: the city of Zabrze, the Silesia region in the south of Poland (flats for the elderly)! as well as "Puls 5" - an adapted multifunctional building in the revitalized post-industrial area of Untere Hard in Zurich, Switzerland, and "Park Hill" - modernized buildings in the housing area in Sheffield, England (flexibility in the process of revitalization and modernization of the heritage, flexibility of elevations). The results will concentrate on functional, constructional and esthetical adaptation aspects and flexibility of buildings with flats as a sign of time evolution, considering the need to improve the life quality of people, the preservation of heritage, and finally, sustainable development. © 2015 IAHS.

BACKGROUND: Overweight and obesity are metabolic disorders affecting both adults and children. Effective treatment of these conditions is focused on decreasing the body mass, through individually tailored and well balanced diets, along with increasing physical activity. Obese persons often, however, choose high protein diets for losing weight. Recently in Poland, the high-protein Dukan-diet has become very popular.OBJECTIVES: To assess dietary consumption in women adopting the Dukan-diet, including intakes of protein, fat, carbohydrate as well as vitamins and minerals.MATERIALS AND METHODS: Subjects were 51 women aged 19-64 years on the Dukan-diet, who were surveyed by individually conducted interview. Women were asked to provide typical menus from each phase of their diets. Quantitative dietary intake assessment was achieved by an officially used 'Photograph album of foodstuffs and dishes' as custom-designed by the National Food and Nutrition Institute (IZZ) in Warsaw.RESULTS: Protein intakes in all subjects were excessive, especially those of animal origin when compared to recommended nutritional standards. In contrast, dietary carbohydrate intakes were low due to poor consumption of fruit and vegetables. Mineral and vitamin intakes revealed high potassium, iron and vitamins A, D and B2, but low vitamin C and folates. Women's average weight reduction after 8-10 weeks of dieting was approximately 15 kilograms.CONCLUSIONS: Many nutritional abnormalities were found in women on the high protein Dukan-diet. Adopting this diet in the long-term may pose health threats through acquiring kidney and liver disease, osteoporosis and cardiovascular disease.

A quality of classification of studied phenomena, or objects depends on the selection of variables (features) and criteria of the assessment. The choice of financial ratios in the study of financial standing of companies is crucial. The article presents the proposal to apply measure of quality of selection to choose sub-optimal subsets of financial ratios that best describe the subject of the research, which is the company. The aim of this study is to present a solution that allows the selection of financial ratios with a very high cognitive value, enabling the building of integrated measures assess the financial condition of the company. The presented results show the process of selection of the five-elements subset from the set of 13 financial ratios. © Springer International Publishing Switzerland 2016.

The article presents the research results of normality distribution of financial ratios. Distributions are presented in the form of histograms and probability distribution density function of the ratios. The study normality of the ratios cover the period of five years. For businesses, the fallen was the period from one to five years before the bankruptcy. But for companies operating it was analogous period of five years in relation to undertakings fallen. © Springer International Publishing Switzerland 2016.

This article presents a range of approximation error measures for reduced mathematical MIMO models of controlled objects. These measures can be of use in evaluations of reduction quality. The impact of selection of a particular approximation error measure as the objective function of the reduction parameter optimization algorithm on the frequency characteristics of the reduced model was analyzed. Particular emphasis was given to those cases where the individual channels of a MIMO model differ significantly from one another. The results are presented on the example of a one-phase zone evaporating tubes model of a BP-1150 steam boiler. © 2015 IEEE.

The aim of this study was to identify the best prognostic parameters for quickly assessing fluid volume status in the context of nutritional status and water balance in older persons and to facilitate decision-making of the general practitioner (GP). This pilot study was conducted with 142 volunteers aged 60 years or older who were Polish students of the University of the Third Age. Inclusion and exclusion criteria for the study were defined. Assessment tools included: the Mini Nutritional Assessment questionnaire (MNA) and the anthropometric measurements. Weight and body composition analysis were determined by Bioelectrical Impedance Analysis (BIA) using the Tanita MC-780 multi frequency segmental Body Composition Analyzer. According to the MNA scale, 89.2% of the sample was wellnourished and 10.8% were at risk of malnutrition. A total of 47.1% participants had normal body mass index, 20.6% were overweight, and 32.3% were obese. The BIA showed that females had more fat mass (FM) compared to males (35.84% vs 23.90%), while men had more free fat mass (FFM) and total body water (TBW; 61.16% vs 45.22% and 53.31% vs 45.22%respectively). There were no statistically significant differences in FM, FFM, and TBW by age. The ratio of Extracellular to Total Body Water (ECW/TBW) was higher in women than in men (46.76% vs 43.66%). Of all measures, only ECW/TBW increased significantly with age and sex, especially after 65 years. We propose that ECW/TBW may be used as the first, simple, and fast indicator of water volume status in the context of nutritional status and water balance in older subjects. Systematic control of the ECW/TBW by GP or nurse may increase senior independence, resulting in longer self-maintenance at home and reduced hospital admissions.
