Opis:
The development of health education, education in the scope of healthy lifestyles is significantly affected by the mass media, and primarily the Internet, which is an interactive source of information and the space to acquire competencies supporting health. Access to the Internet is getting more and more widespread; also the range of easily accessible content, related to the lifestyle has expanded. Migrations of populations tend to impair the traditionally understood image of the urban and rural environments. Technological advances in the field of transport communications and IT have also reduced the distance between the two discussed environments. The aim of this study was to assess the level of pro-health behaviors of women who are interested in a healthy lifestyle, and who live both in the countryside and in large cities. The study involved 78 women from the towns with up to 3 thousand inhabitants and 130 from the cities with a population over 100 thousand inhabitants. All research participants were active participants in one of the largest health services for mature women in Poland. The research was part of the PARP project -Global health problems, implemented by the Foundation ‘Smak Żcia’. Standardized research tools Health Behavior Inventory were applied according to the adaptation of Z. Juczyńki. As many as 30% of patients achieved a low level of pro-health behaviors, 45% obtained an average score, and only 25%-a high one, which due to an interest in the subject of a healthy lifestyle, occurring as a constant activity on the online health portal, can be regarded as an unsatisfactory result. The research participants (female subscribers of advice from pro-health service) willing to share their experience, commented on a variety of content related to health issues, however, the level of their health behaviors did not differ significantly from the average values for the Polish population. There was no statistically significant difference in the level of realized health behaviors between women living in rural and metropolitan environments. Research confirmed that Internet theme services concerning issues of a healthy lifestyle, are a chance to equalize disparities in pro-health behaviors, and consequently - in health itself, thus initiatives of raising interest in health education through the mass media ought to be supported.

Opis:
The effect of In-flush technique application to the MBE-grown structure with self-assembled quantum dots is investigated in this work. The microphotoluminescence from structures with the InAs/GaAs dots grown with and without the In-flush has been investigated. We focus our attention on "not fully developed" dots, which can be clearly distinguished in the spectrum. The dots have also been identified in the transmission electron microscopy analysis of the structures. The In-flush does not influence a broad energy range of those features. Instead we have found that the anisotropic exchange energy splitting of neutral excitons confined in those in the structure grown with In-flush is substantially lower that the splitting in the structure with no In-flush. This observation confirms that the In-flush leads not only to better uniformity of self-assembled quantum dots but also to reduction of lateral potential, anisotropy, which is believed to result in the neutral exciton splitting.

Opis:
In this work we present analysis of carriers dynamics in samples of GaN nanowires grown on silicon. The samples exhibit bright luminescence of bulk donor-bound excitons at 3.472 eV, surface defect-bound excitons at 3.450 eV (SDX) and a broad (0.05 eV) band centered at 3.47 eV caused probably by single free exciton and bi-exciton recombination. The SDX emission has long lifetime τ = 0.6 ns at 4 K and can be observed up to 50 K. At higher temperatures luminescence is dominated by free excitons. The broad excitonic band is best visible under high excitation, and reveals fast, non-exponential dynamics. We present mathematical model assuming exciton-exciton interaction leading to the Auger processes. The model includes $n^2$ (Langevin) term and describes well the non-exponential dynamics of the excitonic band.

Opis:
We report on growth of GaN nanocolumns by plasma assisted MBE on (111) silicon substrates and on their characterization. The nanocolumns nucleate on the substrate spontaneously without use of any catalyst, probably by the Volmer-Weber mechanism. Transmission electron microscopy analysis shows high crystalline quality of GaN nanocolumns and their good alignment with the c-axis being perpendicular to the substrate. Preliminary results on use of GaN nanocolumns in gas sensor devices are presented.

Opis:
It has recently been shown that potential fluctuations in a wetting layer, which accompanies InAs/GaAs quantum dots can localize excitons. Neutral excitons and biexcitons and charged excitons were identified. In this communication we report on studies of properties of the excitons over wide temperature range (T < 70 K). The micro-photoluminescence measurements enable investigation of excitons localized in a single potential fluctuation. Temperature-induced broadening of the neutral exciton as well as a quenching of the charged exciton at temperatures higher than 50 K are observed and discussed.
