The main goal of this paper is to present coupled Computational Fluid Dynamics and structural analysis for the precise determination of wind impact on internal forces and deformations of structural elements of a longspan roof structure. The Finite Volume Method (FVM) serves for a solution of the fluid flow problem to model the air flow around the structure, whose results are applied in turn as the...
The article presents the selected properties of methyl esters of rapeseed oil produced in the process of innovative waste-free production technology. The basis for the proposed technology is the process of transesterification of rapeseed oil with methyl acetate carried out in the presence of an alkali catalyst and with the use of ultrasounds. As a result of tests carried out, optimum conditions for...
Cryopreservation in liquid nitrogen (–196°C, LN) is the method of long−term conservation of plant tissues, which has been evolving for many of seed of woody plant species. During cryopreservation protocol to LN in plant cells take place the supercooling tissue water or vitrification, which allows the successful storage. Water content was a significant determining factor with survival of cryostored...
W artykule przedstawiono przykłady rekonstrukcji komputerowych najsłynniejszych zabytków architektonicznych starożytności w laboratoriach całego świata przy użyciu najnowocześniejszych technik grafiki komputerowej. Celem artykułu jest przede wszystkim ocena archeologicznej i historycznej wartości tych wirtualnych wizualizacji, zależnej od ilości i jakości świadectw, na podstawie których zostały one...
