Opis:: The characterization of nanostructures is a topic of vital interest, since the dimensions of commercially available semiconductor devices are now in a range, where quantum size effects become evident. In this paper, various methods are presented to characterize low-dimensional structures. Magnetic depopulation, tunneling, far infrared transmission, photo-conductivity and magnetophonon resonances are used to determine the low-dimensional sub-band energies. For each method, the special features are discussed and it is demonstrated that the different methods yield different, complementary information.

Opis:: Tunneling processes in double-barrier GaAs/AlAs diodes with an incorporated AlGaAs pre-barrier were studied under hydrostatic pressure. The electrical characteristics resulting from a pre-barrier on the side of the emitter can be explained at 1 bar, solely by the Γ-profile: increasing pressure shows that the pre-barrier does not reduce the Γ-X tunneling. A pre-barrier on the collector side leads to charge buildup at the X minimum within the AlAs collector barrier.

Tytuł:: Education in Possession – how to Achieve Happiness in the Materialistically Oriented World
Autorzy:: Górnik-Durose, Małgorzata E.

Opis:: In the article reasons for “education in possession” are introduced. The author defines the concept of “education in possession” in terms of educational objectives and means of their realization which are to help people in conscious and responsible choices related to fulfilling their vital needs using effectively available material resources. In the approach applied instead of looking at the problem from the point of view of idealistically set goals and directions of education, a question has been asked if acquiring and possessing material goods can provide clear advantages for individuals in relation to the quality of their lives. Such advantages are considered to serve as standards for the appropriateness of people’s choices and at the same time as benchmarks for educational objectives. The author, drawing conclusions from the results of numerous studies on the relationship between psychological well-being and material wealth, shows that wealth fulfils its function in relation to the fulfillment of human needs in the area of necessary comfort and in relation to the effectiveness of individuals’ everyday activities. Beyond that material strivings seem to be psychologically disadvantageous and lose their importance. After reaching a certain level being wealthier does not mean being happier, because the obtained surplus of possessions, being unnecessary, requires dealing with additional costs of the psychological nature. These psychological costs of material wealth have their roots in external and internal factors. The former are connected with objective discrepancies in wealth within societies and cultural rules and values, the latter with a type of motivation for acquiring material possession, nature of material goals, an individual level of materialism, a conflict between values, and a way of managing material resources. The avoidance of the costs described is treated in the article as a major educational objective in the field of “education in possession”.

Opis:: Badania polegały na ocenie wpływu temperatur 5, 10, 15°C na rozpoczęcie (T₁, równomierność (T₉₀₋₁₀), procent i średni czas wschodów (T) słonecznika zwyczajnego ‘Sonnengold’ oraz rozwój siewek w okresie 50 dni. W tym celu przez pierwsze 5 tygodni od wysiewu kiełkujące nasiona i uzyskane z nich siewki przetrzymywano w poszczególnych temperaturach przez różny okres, a następnie przeniesiono je na pozostały okres do 15°C. Oceniono również dynamikę wzrostu korzenia i hypokotylu w ciągu 8 dni w temperaturach 5, 10, 15, 20, 25, 30°C. Badania wykazały, że optymalną temperaturą dla wzrostu korzeni i hypokotylu było 25°C. Temperatury wyższe i niższe hamowały wzrost siewek. Korzeń słonecznika był w większym stopniu wrażliwy na oddziaływanie niekorzystnej temperatury niż hypokotyl. Optymalnym terminem wysiewu nasion słonecznika zwyczajnego ‘Sonnengold’ był okres, gdy temperatura gleby wynosiła 5°C i utrzymywała się na stałym poziomie nie dłużej niż tydzień, a następnie przez kolejne 0-2 tygodnie wzrosła do 10°C i potem przez 2-4 tygodnie do 15°C.
The effects of temperatures of 5, 10, 15°C on the time for the first seedling to emergence (T₁), uniformity (T₉₀₋₁₀), percentage (%) and the mean emergence time (T) of sunflower ‘Sonnengold’, as well as their further growth during 50 days were examined. For this purpose the germinated seeds and seedlings were kept at these temperatures for various periods during 5 weeks and then transferred to 15°C for the rest of the time. Additionally the dynamics of root and hypocotyl growth during 8 days at the temperature of 5, 10, 15, 20, 25 and 30°C were investigated. The studies showed that the optimal temperature for the growth of sunflower ‘Sonnengold’ roots and hypocotyls was 25°C. The temperatures higher and lower than 25°C remarkably inhibited the growth of seedlings. The sunflower roots were more sensitive than hypocotyl to the unfavourable temperatures. The most suitable time for seed sowing was the moment when the temperature of soil reached 5°C for no longer than one week and then for the next 0-2 weeks rose to 10°C and afterwards for 2-4 weeks to 15°C.
