Opis:
Purpose: The aim of this article is to understand how Polish winemakers make decisions about the type of production; to identify barriers of implementation of organic practices organic, to understand the values that are behind the decision-making process in the context of the three areas of sustainable development and present recommendations in relation to the conclusions. Design/methodology/approach: Methodological approach is based on Analytical Hierarchical Process (AHP). The study included 18 values grouped according to belonging to the environmental, social and economic area. The importance of each value was compared by the respondents with the other values, which allowed to understand the course of the decision-making process in the context of the goals and importance of environmental, social and economic values represented by organic and conventional winemakers. Findings: The research revealed significant differences in the approach to the environmental and economic values. Conventional and organic winemakers differ in the hierarchy of values in the context of the triad of sustainable development (economy, society, environment), and the key values taken into account by conventional winemakers are pecuniary values, in contrast to organic winemakers, for whom non-economic values are key, in particular from the area of environmental issues. Organic production is perceived by the surveyed winemakers in ideological rather than business terms. Conventional winemakers see the organic production as more complicated and problematic. Practical implications: This is a significant problem showing the lack of education and awareness in relation to the theory and practice of an organic production. This situation should be alarming for agricultural advisory institutions and the entities of administration responsible for the implementation of sustainable development assumptions. Originality/value: This paper fills a gap in literature science, by the Authors' knowledge, this is the first article to use the AHP method to determine how winemakers make decisions about the type of production.

Opis:
Artykuł zawiera ocenę jakości wydruku elementów wykonanych w technice druku DLP, poprzez analizę projekcji otrzymanych z tomografu wolumetrycznego i konwencjonalnego. Podczas analizy określono czy możliwym jest wykonanie fantomu do CBCT z wydruku światłoutwardzalnego przy pomocy drukarki DLP. Badania tomograficzne miały na celu określenie obecności wtrąceń materiałowych i pęcherzy powietrza, mogących dawać efekt odbicia promieni rentgenowskich. Przeanalizowano ilość pochłanianej wiązki promieniowania poprzez pomiary wartości jednostek Hounsfielda dla wielu obszarów próbek.
The article has been devoted to an evaluation of the print quality of elements made in the DLP printing technique, which was obtained as a result of the analysis of the projection from the volumetric and conventional CT. During this analysis the presence of air bubbles, material inclusions and other artifacts, which may give the effect of X-ray reflection, was determined. The amount of absorbed radiation beam was also analysed by measuring the Hounsfield unit values for many sample areas.

Opis:
The article has presented the method of 3D Digital Light Processing printing as one of the technologies used for rapid prototyping of dental models and making elements of dentures. in this work the research was presented, which the aim was to determine the effect of additional exposure time on the properties of the obtained printouts. Dynamic Mechanical Analysis test showed significant differences in stiffness between uncured specimens as well as specimens cured for 10, 20 and 30 minutes. in turn the obtained TG and DTG curves allowed to determine the most optimal curing time for DLP printouts. These studies provide the basis for determining the most appropriate method for handling printouts after the process of printing from liquid resin, so that they are the best possible quality for dentists and prosthodontists.

Opis:
The article presents the results of research on selected thermal, mechanical properties, as well as the microscopic structure of filaments and details made on a 3D printer in FDM technology. The materials used in the study were PETG (polyethylene terephthalate doped with glycol) and PLA (polylactide) doped with copper. As part of the study, Differential Scanning Calorimetry (DSC) was performed in order to determine the temperatures of phase transformations and changes in melting enthalpy values of filaments before the printing process and also elements made of them. The second part of the research was electrocorrosive ageing process of printouts, carried out in the Simulated Body Fluid solution in a device generating 0.3 A direct current, voltage with value 4.3 V for the entire duration of the test, which was 720 h. After this process DSC test was conducted again. The next stage of the research was Dynamic Mechanical Analysis (DMA) of printouts before and after electrocorrosive ageing process. This test was carried out to characterize the dynamic-mechanical properties as a function of frequency, temperature and time. Additionally, microscopic analyses of the surfaces of the tested printouts were performed in order to assess the changes after electrolysis.
