ECOLOGICAL RISK ZONE MAPPING FOR HIGH-SULPHUR GAS EXPLOITATION WITH GEOGRAPHIC INFORMATION SYSTEM
Ecological Risk Analysis Geographic Information System Landscape Ecosystem Spatial Analysis Mapping
2015/12/28
The exploitation of fossil fuels is a main factor for environmental deterioration, especially the large-scale exploitation of high-sulphur gas because of the toxicity of sulphur. There exist many diff...
A role of reductones in the monitoring of sulphur dioxide content in wines during their maturation and storage
sulphuration titrated acids tartaric acid
2014/7/10
The content of free SO2 (1.3–37.9 mg/l and 5.3–19.7 mg/l for 2009 and 2010) and total SO2 (38.3–272.0 mg/l and 52.0–102.1 mg/l for 2009 and 2010) for individual wines was in a broad interval. Results ...
Ionic Liquid Assisted Extraction of Nitrogen and Sulphur-Containing Air Pollutants from Model Oil and Regeneration of the Spent Ionic Liquid
Ionic Liquids Extraction Air Pollutants Nitrogen Compound Sulfur Compounds
2013/3/12
Removal of air pollutants, such as nitrogen and sulphur containing compounds from a model oil (dodecane) was studied. An ionic liquid (1-ethyl-3-methylimidazolium chloride [C2mim] [Cl]) was used as an...
Modification of oxygen and sulphur inclusions in steel by calcium treatment
modification oxygen and sulphur inclusions calcium treatment
2009/10/23
In the article, the results of examinations of changes in deformability of oxygen and sulphur inclusions in structural steel processed with calcium are discussed. The results obtained imply the positi...
The diffusion of sulphur from moulding sand to cast and methods of its elimination
Moulding sands Sulphur
2011/4/1
The care of high quality castings requires taking into account the possible negative influence of decomposition products of moulding and core sands on the structure of castings produced. Such products...

tomatoes lycopene colour sulphur nitrogen fertilisation
2014/3/10
The effects of different sulphur (S) fertilisers (ammonium, sodium, potassium and calcium sulphates) in combination with nitrogen (N) on plant growth, yield and quality of fruits were investigated in ...
Effective inoculation of low-sulphur cast iron
Inoculation Cast iron Dendrites Structure Mechanical properties
2011/3/17
The study proves that by introducing the disintegrated steel scrap to low-sulphur cast iron still before the inoculation carried out with a conventional graphitising inoculant, the mechanical properti...
