Estimation of storage losses of fuels – Tanks software as a decisions – making tool for construction, maintenance and modernization of gasoline tanks

Estimation of storage losses of fuels - Tanks software as a decisions - making tool for construction, maintenance and modernization of gasoline tanks PORZYCKA-SEMCZUK K Please cite as: CHEMIK 2011, 65, 10, 974-982 TANKS is a Windows-based computer software program that estimates emissions formed as a result of volatile organic compounds storage, also including petroleum fuels. The estimations are possible for the tanks with fixed and floating roofs of different construction. There are presented some examples of this program application as a supplementary tool for...

Study of antioxidant properties of green tea extract

Study of antioxidant properties of green tea extract SIKORA E., OGONO WSKI J. Please cite as: CHEMIK 2011, 65, 10, 968-973 The aim of this work was the study of antioxidant properties of green tea extracts. Effect of kind of the solvent (ethyl alcohol, propylene glycol and water) and types of extraction (extraction in Soxlet apparatus and maceration) on the content of quercetin-3-rutinoside and the antioxidant efficiency of the extracts were investigated using UV-vis spectroscopy. The antioxidant properties were determinate on the basis...

Solid Lipid Nanoparticles ? characteristics, application and obtaining

Solid Lipid Nanoparticles ? characteristics, application and obtaining LASOŃ E., OGONO WSKI J. Please cite as: CHEMIK 2011, 65, 10, 960-967 Solid lipid nanoparticles (SLN) have attracted increasing attention as novel carrier systems for active substances, not only in farmaceutic, but also in cosmetic and food industry. Being in the market for about 20 years they gradually replace traditional colloidal systems while maintaining their advantages. In this paper general characteristic of solid lipid nanoparticles was done indicating their structure and properties. The most frequent production...

Shale gas ? unconventional natural gas

Shale gas ? unconventional natural gas MACHOWSKA H. Please cite as: CHEMIK 2011, 65, 10, 954-959 The need to ensure energy security for Europe and the world, and development of mining technologies has drawn attention to unconventional natural gas deposits, in particular the shale gas. Basing on the geological data and the gas potential analysis, it is assessed that there are considerable deposits of shale gas on the territory of Poland. However, the technology of mining unconventional gas requires superb geological, geochemical and environmental...

Hair conditioning foams formulations

Hair conditioning foams formulations OLSZAŃSKA M., SADOWSKI R., OGONO WSKI J. Please cite as: CHEMIK 2011, 65, 10, 936-945 Seven conditioning foams with styling properties were prepared. Their physicochemical and functional properties such, as pH, foam density, total solid content, curl retention, antistatic properties and drain time were determined. Moreover, the hair structure was analyzed by SEM microscopy. It was found that the mechanism of the hair conditioning by keratin hydrolyzates of low degree of hydrolysis relies on formation of a protective film on the...

Comparison of physicochemical properties of select natural fats and their methyl esters

Fatty acids methyl esters. Comparison of physicochemical properties of select natural fats and their methyl esters SKRZYŃSKA E., MATYJA M. Please cite as: CHEMIK 2011, 65, 10, 923-935 This article presents the current state of biodiesel production in Europe, with particular attention putted onto the quality requirements in different countries, and differences between methyl esters properties derived from various raw materials. The properties of fatty raw materials available in the domestic market, such as: rapeseed, sunflower, corn, linseed, soybean, olive and castor oils, and also the...

The process of waste incineration in the tanning industry

The process of waste incineration in the tanning industry Wiecz orek -Ciur owa K., Famielec S., Woźny Z., Fela K Please cite as: CHEMIK 2011, 65, 10, 917-922 The article describes the conception of tannery waste treatment by combustion process in the specially designed system. The technology should provide tanneries with comprehensive solution for tannery waste problems. The additional advantage of the technology is the possibility to reuse energy from waste in tanning processes. Moreover, the characteristics of tannery waste in respect of its combustion...
