PUBLIC TRANSPORT IN THE ERA OF AUTOMATISATION AND SHARING ECONOMY
2019
Background. Over half of the world's population lives in urbanized areas, cities emit over 75 % of global greenhouse gases [1]. One of the sources of pollution is transport. Therefore, striving for the development of sustainable transport systems in cities is crucial. Observing global trends in mobility allows noting the development of economy, automation and electrification of the automobile. These tendencies seem to have enormous potential to improve the functioning of transport systems and to maximize economic and environmental effects. Therefore, the aim of this article is to identify the benefits of using low-carbon autonomous vehicles, to spread the sharing mobility and to identify po…
Separation of chitosomes and secretory vesicles from the ?slime? variant of Neurospora crassa
1987
Cells from the “slime” variant of Neurospora crassa were broken in isotonic conditions by use of triethanolamine buffer plus EDTA. After removal of large membranous structures by low-speed centrifugation, chitosomes and secretory vesicles were separated by means of gel filtration, precipitation of membranous contaminants with Concanavalin A, and centrifugation in sucrose or glycerol gradients. Polypeptidic composition of fractions enriched in secretory vesicles or chitosomes was found to be distinct. By these criteria we concluded that chitosomes and secretory vesicles represent different populations of microvesicles. Both microvesicular populations appeared free of endoplasmic reticulum an…
Electron microscopy and biochemical characterization of a 350-kDa annular hemolymph protein from the keyhole limpet Megathura crenulata
1994
The isolation and biochemical characterization of an annular non-hemocyanin hemolymph protein from a marine gastropod, the Californian giant keyhole limpet (Megathura crenulata) is presented. By analytical ultracentrifugation, the protein has a sedimentation coefficient of 12S and molecular mass of approximately 350 kDa. The subunit mass, obtained by SDS/PAGE in the presence of -SH reagent and 8 M urea, is approximately 35 kDa, thereby indicating the presence of 10 subunits in the native molecule. By negative staining, the protein is revealed in one predominant image projection as a pentagonal approximately 8 nm ring-like structure with an approximately 2-nm stain-filled centre and, in anot…
Organocatalytic Enantioselective Friedel-Crafts Alkylation of 1-Naphthol Derivatives and Activated Phenols with Ethyl Trifluoropyruvate
2015
An organocatalytic enantioselective Friedel–Crafts alkylation of a series of substituted 1- naphthol derivatives and activated phenols with ethyl trifluoropyruvate, catalyzed by a quinine-derived squaramide, is presented. Good yields and high to excellent enantioselectivities of the Friedel– Crafts alkylation products were obtained.
Evaluation of biomass activity and wastewater characterization in a UCT-MBR pilot plant by means of respirometric techniques
2011
Abstract Over the last two decades, Membrane Bioreactors (MBRs) emerged even more for wastewater treatment, ensuring high removal efficiencies as well as very small footprint requirements. Indeed, in this kind of process, a modification in biomass activity and viability can exist compared to that of a CAS process. In this context, respirometric analysis represents a reliable tool in order to evaluate the actual biomass kinetic parameters, to insert in mathematical models in the design phase, as well as to monitor the biomass viability, especially when these processes are operated with high SRT values. The paper presents some results of respirometric techniques applied for the characterisati…
Tracing activation efficiency of the bio-filtration bacteria in a recirculating aquaculture system using stable isotope analysis
2016
One challenge in starting a new recirculation aquaculture system (RAS) is to find the most efficient method to activate the nitrifying bacterial biofilm in the bio-filtration system. It has been suggested that chemical startup with ammonia and nitrite surpasses the “cold start” method where biofilm originates from the fish introduced to the un-activated system. However, there is no information on how the start-up method affects the actual nitrification activity of the bio- filtration system. The objectives of this study were to evaluate how different activation techniques affect the overall function and the nitrification activity of the bio-filtration units, and the interactions between het…
