O kolorach posiłków, tajemnicy suszenia oraz przymusie dla producentów mówi dr Anna Michalska z Instytutu Rozrod Zwierząt i Badań Żywności PAN w Olsztynie.
Products of complex geometry, aerodynamic shape and high quality surface finishes are among the most difficult to produce by using stamping methods. When additionally materials with special properties are intended, the task of determining their technological character becomes difficult to solve without the use of physical and numerical methods of process modeling. The paper presents the results of modeling the process of producing a single tube of the jet engine tubular diffuser subassembly. This is a product representative of such a complex geometry one. The charge material for this element requires resistance to operating conditions at elevated temperature and high durability. Therefore, an Inconel type nickel superalloy was proposed for the charge material. In the solution of designing the method of producing a single diffuser tube task, the capabilities of the AutoGrid automatic strain analyzer and the FEM simulation software Eta / Dynaform 5.9 were combined. Numerical simulations of different variants of the manufacturing process of the diffuser tube were made using the Eta / Dynaform 5.9 software. The results of forming simulations became the basis for the alternative technological cycle design of this drawpiece.
In the article the author discusses the relationship between education and socio-cultural needs. The socio – cultural reality is the reality of a permanent change. It is difficult to describe and even more difficult to understand. The specific character of qualitatively new changes in the relations between globality and locality implies a completely new perception of reality, ways of interpreting the world, and a new quality of judgments about the condition of the modern man. This reality is also a ”multiplicity of worlds”, which means a large number of possibilities to create oneself. What individuals perceive as their ”own” has the biggest developmental potential when it is worked out on the proactivity path. proactive people are distinguished by interrelated features: the search for a possibility of change (the environment examination, going beyond limitations of a given situation), establishing effective and change oriented goals (opening new paths of action), foreseeing problems and remedia measures (the analysis of one’s own achievements, looking for signals of threats or dangers), looking for new ways of achieving goals (the ambition is to make a new tradition).
In knowledge based economy, which actually reflects the knowledge oriented modern society, career development of its members becomes the key factor, same as investing in career “portfolio”. In the article a career construct is invoked as an individual’s property considering individual career choices, individual career development planning and monitoring strategies. When addressing career related matter, one cannot overlook the issue of subjective meaning given to a career in the context of satisfactory outcome and success achievement experienced by the subject. Cognitively interesting issue addressed by the author are the results of research into evaluation of one’s own chances to succeed from the perspective of university students who are in the transition period from academic education to entering a job market.
The fusulinid foraminifers of Schellwienia arctica (Schellwien, 1908) have been investigated from Polakkfjellet Mt., south Spitsbergen, and used as biostratigraphic marker for the latest Carboniferous earliest Permian strata of the Treskelodden Formation. A series of thin sections enable to investigate the internal structure and growth pattern of individual specimens. The observed variation of growth suggests dynamic environmental conditions at the investigated location and most likely over one-year long life span of this foraminifer.
