High Temperature Drying Process of Beech Wood (Fagus sylvatica L.) with Different Zones of Sapwood and Red False Heartwood
PublicationThis study examined the changes in the properties of beech wood (Fagus sylvatica L.) after intense drying. Beech wood with false red heartwood was selected as the test specimen. The test samples had dimensions of 50 mm thickness, 180 mm width, and 350 mm length. The specimens were divided into two groups, false red heartwood and sapwood. These specimens were selected with different angles of the growth rings (radial and tangential)....

Economical wood sawing with circular saw blades of a new design (Ekonomicno piljenje drva kruznom pilom novog dezajna)
PublicationMaterial-saving and energy-saving belong to the basic requirements imposed on contemporary manufacturing processes. The realization of these processes gives measurable profi ts, not only economical butalso ecological. In the case of wood sawing with circular saw blades, material- and energy-savings are dependent on total overall set of teeth (theoretical kerf) and teeth position accuracy in relation to the workpiece. Hence, it...

Applications of sample preparation techniques in the analysis of pesticides and PCBS in food
PublicationPestycydy oraz anality z grupy polichlorowanych bifenyli (PCB), można znaleźć w żywności w niewielkich stężeniach, jednak ich zdolność do kumulacji i toksyczność powodują konieczność oznaczanie tych związków w żywności. Analiza próbek żywności pod kątem obecności pestycydów i analitów z grupy PCB przysparza wiele trudności ze względu na specyfikę przygotowania próbki w oparciu o wieloetapowe operacje oczyszczania próbki zawierającej...

Recent advances in reinforced bioplastics for food packaging – A critical review
PublicationRecently, diversifying the material, method, and application in food packaging has been massively developed to find more environment-friendly materials. However, the mechanical and barrier properties of the bioplastics are major hurdles to expansion in commercial realization. The compositional variation with the inclusion of different fillers could resolve the lacking performance of the bioplastic. This review summarizes the various...

Antioxidants: a premature scientific hypothesis that reshuffled the traditional food pyramid
PublicationAntioxidants present in substantial amounts in foods, plant-based products in particular, have been suggested as chemopreventive agents that can curb the development of undesirable health effects caused by oxidative stress simply by enriching diet in such compounds. This idea has been enthusiastically accepted by consumers, as well as food and pharmaceutical industry, and created great demand for products containing antioxidant...

Sample preparation techniques for determination of pesticide residues in food samples
PublicationPesticides are very important in increasing the efficiency and quality of agricultural production. They are applied in many spheres of life, not only in agriculture, and their applications are expanding. Despite their numerous merits, pesticides are some of the most toxic substances contaminating our environment and have a negative impact on the human health. Properties of pesticides such as stability, ability to bioaccumulation...

Good practices in requirements, project and risk managment in educational IT projects
PublicationOne can find many learning aids and simulations of physical phenomena on the market - provided as a standalone application or as part of an educational package. However, only a few of them allow for the building of interactive experiments: experiments similar to those that should be conducted in physics laboratories at schools. Gdańsk University of Technology decided to fill this market niche by designing and constructing a set...

A standard analytical method as the common good and pollution abatement measure
PublicationA standard method can be considered as a common-good “resource,” and the solution to “the commons” problems usually lies in societal self-organization. The multi-criteria decision analysis (MCDA) was applied to model complex phenomena, such as the standard selection for imidacloprid determination. In this process, the standard was self-selected by the analytical chemistry society. The results show that analytical chemistry is a...

The influence of food phytochemicals on cyclic phosphodiesterase 4 (PDE4) activity
PublicationCyclic phosphodiesterase 4 (PDE4) belongs to family of cyclic phosphodiesterases, which are expressed predominantly in inflammatory cells, airway smooth muscles, cardiovascular tissues and brain. Inhibitors of this family of enzymes found medicinal applications as antidepressants, antiinflamatory drugs (mainly in airway diseases) or antiasthmatics (Ibudilast). PDE4 inhibitors are also being tested for preventing the development...
