Opis:: This paper discusses the matter of fault detection by the diagnosticians of a Regional Vehicle Inspection Station (RVIS) in trucks. The analysis data were obtained directly from RVIS. The produced results were presented as bar graphs indicating the trend change from 2014 to 2018. Thus obtained trends were described by formulae and used to calculate the probability of a fault from the analysed group appearing. The obtained data dependency can be used to calculate the probability of a fault appearing in a truck during a year of operation.
W artykule omówiono zagadnienia dotyczące wykrywania uszkodzeń przez diagnostów na Okręgowych Stacjach Kontroli Pojazdów w pojazdach ciężarowych. Dane do analiz pozyskano bezpośrednio z OSKP. Uzyskane wyniki przedstawiono w postaci wykresów słupkowych z wskazaniem trendów zmian w okresie od 2014r. do 2018r. Uzyskane trendy opisano równaniami i obliczono prawdopodobieństwo zaistnienia usterki z analizowanej grupy układów. Dzięki uzyskanym zależnościom można szacować prawdopodobieństwo wystąpienia usterki pojazdu ciężarowego w rocznym okresie eksploatacji.

Tytuł:: From Openness to Commercialisation - Teachers Self-presentation in the Blogosphere

Tematy:: teacher blogosphere

online self-presentation
Opis:: The main research question of the text is: what are the ways of teacher self-presentation in the blogosphere? The aim of the analyses was to reconstruct the meanings given by teachers to their own activity in the blogosphere, assessing the potential of blogs in creating the image of the teacher as a professional. Internet ethnography (i.e. cyberethnography, netnography) was used to analyse the blogs. The selection of the research sample was a two-stage process. In the first stage, the teacher blogosphere was reviewed: more than 70 blogs by English teachers, 50 by Polish teachers and 10 by history teachers were selected. A selection of these was made, taking into account: the timing of the activity (more than one year), the frequency of content updates, the regularity of the entries, and the hypertextual diversity. The following blogs were subjected to qualitative analysis: Baba od polskiego, Kreatywny Polonista, DoKlasy, BB's Playground, Hummingbirds els. Teacher self-presentation was the main research category. A number of features of diaries have been found in the content of the blogs: the process of shaping one's “I”, the embeddedness in the present, the systematic nature of the entries, and the writing and rhetorical practice aimed at influencing the outside world (Maryl, 2013). The “I” presented by teacher-bloggers is characterised by openness, responsiveness, creativity, authenticity, relationality, reflexivity and professionalism. The image of the teacher presented in the blogosphere “seduces”. The analysis confirms the different motivations for “being” in the blogosphere. They relate to responding to young people's expectations for teachers to undertake such online activity and the possibility of co-creating open educational resources. The blog activity of teachers is characterised by the so-called personal branding, i.e. building a personal brand, an image of oneself, which is to convince potential recipients to cooperate. Presenting “yourself” in the blogosphere - enhances, sometimes even improves, the image of the teaching profession in the offline world.

Opis:: In this study the effect of sintering process in different temperatures on microstructure and morphological properties of sintered hydroxyapatite (HAp) was investigated. HAp powder was prepared by wet precipitation method from following reagents: Ca(OH)2 + H3PO4 in an alkaline conditions. Thermal analysis (TA), X-Ray diffraction method (XRD), FT-IR spectrometry (FT-IR) and scanning electron microscopy (SEM) were used to elaborate the phase composition and properties of sintered HAp samples and raw HAp powder as well. The total and apparent density and total porosity of sintered compacts, shrinkage and weight loss during the sintering were also measured. The results show that there is a difference in sintering behavior of synthetic hydroxyapatites depending on sintering temperature. The main differences refer to the loss of mass, shrinkage, changes in porosity and density of the investigated materials.

Opis:: Two recently synthesized groups of acridine cytostatics containing fused heterocyclic ring(s): pyrazoloacridines (PAC) and pyrazolopyrimidoacridines (PPAC) were tested in regard to their in vitro cytotoxic activity towards a panel of sensitive and resistant human tumor cell lines. The obtained results corroborate our earlier hypothesis on the essential role of heterocyclic ring fused to the acridine moiety in the ability of acridine cytostatics to overcome multidrug resistance of tumor cells. The presence, location and kind of substituents considerably influenced both the cytotoxic activity of the derivatives and their ability to overcome multidrug resistance. The same factors also affected the cytostatics ability to differentiate between tumor cell lines with various types of drug exporting pumps.
