Unraveling the nature of universal dynamics in O(N) theories
2020
Many-body quantum systems far from equilibrium can exhibit universal scaling dynamics which defy standard classification schemes. Here, we disentangle the dominant excitations in the universal dynamics of highly occupied N-component scalar systems using unequal-time correlators. While previous equal-time studies have conjectured the infrared properties to be universal for all N, we clearly identify for the first time two fundamentally different phenomena relevant at different N. We find all N >= 3 to be indeed dominated by the same Lorentzian "large-N" peak, whereas N = 1 is characterized instead by a non-Lorentzian peak with different properties, and for N = 2, we see a mixture of two cont…

Problem-Based Learning in Professional Studies from the Physiotherapy Students’ Perspective
2018
The aim of the study was to investigate how physiotherapy students using a problem-based learning approach develop into experts during higher education, and answers the question: How do physiotherapy students at bachelor’s level understand the problem-based learning approach while learning to become professionals? PBL is examined using interpretative phenomenological analysis (IPA) of longitudinal data written by 15 voluntary students from two different higher education institutions and collected during 3.5 years. The main results on the new way of learning strengthen earlier conceptions of the importance of reflection in the learning process. The PBL method activates a reflection process b…
A phenomenological view of pictures in teaching and a novel method for analysing them
2014
In this paper a novel method for analysing the content and teaching potential of pictures is presented. It is the four-field method, which is based on phenomenological thoughts about human experience, which combines factual knowledge with emotions and personal and social meanings. A biological example is given. Around this idea a course unit for using pictures in science teaching was organized. It was used in the training of both primary and secondary level teachers. From picture analysis the course unit proceeds to planning the use of pictures in teaching. A classification of the teaching functions of pictures is presented.
Analysis of a GC/MS Thermal Desorption System with Simultaneous Sniffing for Determination of Off-Odor Compounds and VOCs in Fumes Formed during Extr…
2001
A thermal desorption equipment introducing volatile organic compounds (VOCs) into the gas chromatographic/ mass spectrometric system (GC/MS) with simultaneous sniffing (SNIFF) is a suitable method for identifying the volatile organic off-odor compounds formed during the extrusion coating process of low-density polyethylene. Fumes emitted during the extrusion coating process of three different plastic materials were collected at two different temperatures (285 and 315 degrees C) from an outgoing pipe and near an extruder. The VOCs of fumes were analyzed by drawing a known volume of air through the adsorbent tube filled with a solid adsorbent (Tenax GR). The air samples were analyzed by using…
Bacterial diseases of energy plants

Przedstawiono wyniki badań bakteryjnych patogenów bioenergetycznych roślin drzewiastych (topoli, brzozy), prowadzących do znacznego zmniejszenia zbiorów lub zaginięcia. Opisano różne choroby bakteryjne i patogeny zaznaczonych roślin, objawy tych chorób, charakterystykê obrażeń, rozmieszczenie i szkodliwość patogenów. Przedstawiono charakterystykê głównych chorób bakteryjnych (rak bakteryjny i martwicę bakteryjną kory) oraz mniej niebezpiecznych (mokradła), zarazy bakteryjne, choroby korzeni i gruźlica). Czynnikiem sprawczym bakteryjnego raku jest bakteria Xanthomonas populi (syn. Aplanobacterium populi). Jako towarzysząca mikroflora czynników wywołujących raka przeważają bakterie z rodzaju …

Two positive solutions for a nonlinear parameter-depending algebraic system
2021
The existence of two positive solutions for a nonlinear parameter-depending algebraic system is investigated. The main tools are a finite dimensional version of a two critical point theorem and a recent weak-strong discrete maximum principle.
