Dairy industry liquid products have short terms of validity. Therefore, it has become very popular to produce dairy products in the form of powder. This powder is obtained by a two-step spray drying method. At an initial stage, the raw material is preliminarily dried in a spray dryer (to get 10% moisture). At the following stage, it is thoroughly dried in a vibrating fluidized bed dryer (3-4% moisture). Fluidization is a process, in which dry grains of solid contact fluid to generate a fluidized bed that behaves similarly to boiling liquid. Owing to this process, powder of improved physicochemical properties is formed. The aim of our study was to describe the construction and working principles of a whey vibrating fluidized bed dryer.

Płynne produkty przemysłu mleczarskiego mają krótkie terminy przydatności do spożycia. Dlatego popularne stało się produkowanie sproszkowanych produktów mlecznych. Do produkcji tych proszków stosuje się metodę dwustopniowego suszenia rozpyłowego. W pierwszej fazie surowiec jest suszony w suszarce rozpyłowej (do 10% wilgotności), a następnie dosuszany w wibrofluidyzatorze (3-4% wilgotności). Fluidyzacja to proces kontaktowania się suchych ziaren ciała stałego z płynem, aby wytworzyć złoże fluidalne, które zachowuje się podobnie do wrzącej cieczy. Dzięki temu procesowi powstaje proszek o lepszych właściwościach fizykochemicznych. Celem niniejszej pracy jest opisanie budowy i zasady działania wibrofluidyzatora do serwatki.

The prevalence of clusters with the increased morbidity rate is the area of interest among epidemiologists. Not only does the identification of clusters require collecting precise epidemiological data but it also requires the application of reliable spatial statistics techniques. The identification of atypical clusters in this article is performed using data from the Polish Registry of Congenital Malformations (PRWWR) on children with isolated cleft lip with or without cleft palate; the study was carried out in the Wielkopolska Region (Greater Poland). For this purpose, Kulldorff Scan Statistics and the LISA method were used. Since each technique used in the study focuses on a slightly different aspect of spatial structure, the obtained clusters do not always completely overlap. This study presents and compares the efficiency and accuracy of these two non-standard methods of geo-static analysis in children living in the Greater Poland counties. The study has identified 5 agglomerations with an increased prevalence rate of the examined malformation, no statistically significant cluster has been detected. On the basis of the agglomerations, it was possible to compare the applicability of two statistical methods used in the study. Despite the fact that the located clusters do not always completely overlap, the study has proved similarity in qualifying particular counties for given clusters and areas outside the clusters. Taking into account its applicability and monitoring the process of spatial scanning, the Kulldorff method has occurred more universal and accurate in examining the children with congenital malformations.

Clinical investigations yield huge amount of experimental data which need appropriate processing. High degree of their variability decreases quality of prognostic and classification results. Frequently problem of strong redundancy of variables incorporated into model occurs, produces computational instabilities and in multifactorial models makes the appropriate interpretation of obtained results hindered. In this paper we present the set of mathematical procedures used in comparative analysis of two treatment methods for patients with advanced cervical cancer: radiotherapy and combined treatment of ionizing irradiation and chemotherapy.

W artykule przedstawiono model diody zastosowany w programie PSpice. Podano podstawowe zależności opisujące charakterystykę statyczną oraz przełączania diody. W oparciu o program PARTS zaprezentowano charakterystyki pomiarowe na podstawie, których program oblicza parametry opisujące model. Wyniki pomiarów charakterystyk rzeczywistej diody, porównano z danymi znajdującymi się w bibliotece elementów PSpice. .

The article presents structure model of diodę used in program PSpice. There were delivered basic dependences describing statical and switching characterization of diode. On base of program PARTS were presented measuring - characterizations on the ground of which program calculates parameters model. Results of measurements - characterizations of real diode was compared with data from elements library of program PSpice.
