We mainly aimed to determine how alternative liquid fuels affect the exhaust particle size distributions (PSD) emitted by a medium-speed diesel engine. The selected alternative fuels included: circulation-origin marine gas oil (MGO), the 26/74 vol. %

The main objective of this study was to find out how alternative fuels affect the exhaust gas particle size distribution. The fuels are later intended for marine applications. Along with low-sulfur marine light fuel oil (LFO), a high-speed off-road d

Novel synthesis methods for the preparation of quaternary piperazine derivatives of chitosan were developed. Quaternary ammonium moiety can be selectively inserted into either one or both of the piperazine nitrogens, yielding structurally uniform chi

The suitability of TGA/IR method for the analysis of the degree of substitution (DS) of acetylated starch (SA) was assessed. Ten standard samples were analysed for their DS by hydrolysis method and, those of the standards which could be properly diss

Hyaluronan is a high molecular weight polysaccharide ubiquitously found in the extracellular matrix. It acts as a lubricant in joints and tissues and provides stability and elasticity to the extracellular matrix. In addition, hyaluronan is directly o

In the present study we describe a method to prepare membranes with high hyaluronan synthase activity from human glioma cells by pretreatment of the cells with both testicular hyaluronidase and 4-phorbol 12-myristate 13-acetate (PMA). A 23-fold incre
