The aim of this paper is to characterize a non-standard use of the method of market basket analysis in one of the areas of economy, i.e. public transport. Generally, one of the aims of the market basket analysis method is associating the consumer's market basket – in the case of public transport this being the choice of bus stops in the city area made by passengers. Owing to a new, practical use of this method, it was possible to build an efficient model characterizing the movement of flows of public transport passengers, and assess the degree of transferring (changing lines), thus making it possible to adapt the routes of buses to the needs of people using this particular means of transport, as well as to plot new communication lines.
The data analysis was performed using the Statistica statistical package and its SAL application, i.e. the algorithms used in Data Mining.
The paper presents the impact of the initial processing, cultivar, and storage time on the physico-chemical quality of freeze-dried crisps. Sweet pepper after initial washing and crushing was subjected to further four combinations of the initial processing. The first combination included freezing, the second one blanching in 98°C and 2-minutes time, the third one -dehydration in 2% solution of ascorbic acid and the fourth one -dehydration in 2% solution of sodium chloride. Both types of dehydration were carried out in 70°C for 20 minutes with a 1:4 participation of raw material to osmotic solution. Blanched and dehydrated raw materials were subjected to freezing in -18°C for 24 hours. After the completed process of freezing, the samples were moved to a freezer-drier and were dried by sublimation in -18°C and the reduced pressure of 63 Pa. Based on the research analyses a significant variability of physico-chemical properties of the obtained freeze-dried sweet pepper with regard to a cultivar, processing type and storage time were reported. Freeze-dried yellow sweet pepper was the most similar to the fresh raw material. It was dehydrated in the ascorbic acid solution. The storage time considerably influenced the reduction of the quality properties of sweet pepper crisps.
The paper presents the impact of the initial processing, cultivar, and storage time on the physical and chemical quality of freeze-dried sweet pepper crisps. Sweet pepper after initial washing and crushing was subjected to further four combinations of the initial processing. The first combination included freezing, the second one blanching in 98°C and 2-minutes time, the third one -dehydration in 2% solution of ascorbic acid and the fourth one - dehydration in the 2% solution of sodium chlo-ride. Both types of dehydration were carried out in 70°C for 20 minutes with a 1:4 participation of raw material to osmotic solution. Blanched and dehydrated raw materials were subjected to freezing in -18°C for 24 hours. After the completed process of freezing, the samples were moved to a freezer-drier and were dried by sublimation in -18°C and the reduced pressure of 63 Pa. The research that was carried out proved that the microbiological quality of the obtained sweet pepper lyophilizes was significantly affected by the cultivar, treatment type and storage time. These factors significantly diversified the number of micro-organisms in sweet pepper crisps. No initial processing before sublimation drying caused a considerably average increase of the number of psychrophile and mesophilic bacteria in crisps from both sweet pepper cultivars. A considerable reduction of their total number took place during blanching and dehydration in the ascorbic acid solution and sodium chloride solution. Additionally, along with the storage time, reduction of the total number of psychrophilic, mesophilic bacteria, fungi and yeasts was reported.
Despite a long-term reduction trend, the potato production in Poland compared to EU countries is still very high. Therefore, the aim of the paper was to investigate the impact of mechanical damages and light for various genotypes on glycoalkaloids accumulation. Glycoalkaloids are toxic steroid glycosides that naturally occur in the family of Solanaceae. According to many authors, their presence in plants is related to resistance to a physiological stress inflicted by mechanical damages and infections caused by some microorganisms and insects. The TGA content above 200 mg∙kg−1 in a fresh mass of potatoes is an upper limit that guarantees health safety of food. Studies were carried out on 28 potato cultivars divided into 4 groups. The studies that were carried out after harvesting and after 5 months of storage in the experimental storage room in the temperature of 8°C showed an impact of damages and exposition to light of potato tubers on the content of glycoalkaloids.
Introduction. Due to their dynamic character, allergic conditions pose challenges for modern medicine and constitute a public health problem. Nearly 40% of the general Polish population is estimated to suffer from an allergy. We would like to emphasize that allergies are not some extraordinary ailments; instead, they commonly coincide with or are complications of other systemic conditions. Hence, national health policies should prioritize the development and implementation of ready-to-use protocols that focus mainly on prevention rather than treatment.
Conclusions. In an outpatient setting the care for individuals who suffer from allergies is facilitated by therapeutic teams. Allergy nurses play a special role in this framework, with the scope of their professional duties including diagnostic procedures, treatment, being a mediator for patient education initiated by the therapeutic team. This article focuses on three important types of allergy nurses‘ responsibilities: diagnostic procedures (e.g. skin prick tests), therapeutic procedures (allergen-specific immunotherapy), and selected aspects of medical record-keeping.
