Artykuł przedstawia zagadnienia związane z redukcją czasu przezbrojenia prasy korbowej w przedsiębiorstwie produkcyjnym przy użyciu techniki SMED. Wdrożenie umożliwiło skrócenie czasu przezbrajania bez konieczności przeznaczania na to znacznych środków. W artykule przedstawiono poszczególne etapy wdrażania koncepcji SMED, a także możliwość wykorzystania diagramu Ishikawy, umożliwiającego przeprowadzenie...
Interaction of hierarchical nanoporous carbons(HNCs) with chicken embryo red blood cells (RBC.The purpose of this study was to characterize toxicity of hierarchical nanoporous carbons (HNCs) on chicken embryo red blood cells (RBC). RBC are a perfect model to adapt the hemolysis assay in evaluation of the in vitro blood compatibility of nanoparticles. The samples of blood were treated with different...
Influence of melittin on viability and integrity of cell membrane on grade IV glioma. The grade IV glioma is one of the malignant human tumours. Today there is no effective treatment for this type of cancer. Alternative methods are sought-after in glioma treatment, and lately melittin has been found to be useful in anticancer therapy. The aim of the study was to investigate the effect of melittin...
Carbon nanoparticles as transporters of melittin to glioma cells in in vitro model.Substances derived from nature have natural cytotoxic properties, melittin, the main component of bee venom is one of them. It has the ability to destroy any lipid bilayer, therefore to be used in a cancer treatment it needs to be targeted. The aim is to create the drug delivery system, which would efficiently deliver...
Green synthesis of silver nanoparticles by using aqueous mint (Mentha piperita) and cabbage (Brassica oleracea var.capitata) extracts and their antibacterial activity. The objective of this study was the synthesis of silver nanoparticles (Ag-NP) using leaves of mint and cabbage extracts as the reducing and stabilising agents. The presence of nanoparticles was initially confirmed by the obtained colour...
Data security and energy aware communication are key aspects in design of modern ad hoc networks. In this paper we investigate issues associated with the development of secure IEEE 802.15.4 based wireless sensor networks (WSNs) - a special type of ad hoc networks. We focus on energy aware security architectures and protocols for use in WSNs. To give the motivation behind energy efficient secure networks,...
