Cement is produced by co-grinding clinker, gypsum and other components defined in the Cement Standards like limestone, pozzolans, fly ash and slag. The grinding is usually performed in horizontal ball mills. Gypsum is typically the basic source of sulphates (SO3) in the cement. The effect of gypsum on the cement quality is critical and twofold. It affects two of the main properties of this prod...

This study was focused on the historical evolution of waste management policy carried out by Spanish industry devoted to titanium dioxide pigments manufacturing for minimising its environmental impact. challenge achieved modifying original chemical process and converting originally dissolved sulphate sulphuric acid present in final streams factory into minerals (melanterite FeSO4·7H2O, szomolno...

ABSTRACT: Glycosaminoglycans (GAGs) are long-chain polysaccharides that divided into sulphates and non-sulphates, these being chondroitin sulphate, heparan dermatan heparin sulphate the only non-sulphate in group is hyaluronic acid. GAGs obtained from animal tissue by an expensive low-yield extraction process; however, they highly commercially valued exploited biomedical market. Their disacchar...

Previous studies have indicated that CD44 isoforms, spliced with variant exons, are heterogeneously glycanated with chondroitin sulphate and heparan sulphate chains. Because such alternative splicing may regulate divergent biological effects of the specific isoforms, we analysed the consequences of this process on the composition and structure of the chondroitin-sulphate chains. Recombinant chi...

BACKGROUND Carbonated and non-carbonated beverages manufactured based on mineral and spring waters have been present at the Polish market shortly, and their production and sales are regularly growing. The products have become commonly known as flavoured waters. OBJECTIVE The aim of the work was to identify and assess the content of carbohydrates used for sweetening mineral and spring water-ba...

AIMS Through biodesulphurization (BDS) is possible to remove the sulphur present in fossil fuels to carry out the very strict legislation. However, this biological process is limited by the cost of the culture medium, and thus, it is important to explore cheaper alternative carbon sources, such as Jerusalem artichoke (JA). These carbon sources usually contain sulphates which interfere with the ...
