Sulphur in coil1 is il major environmental concern. The use of coal for combustion requires the control of sulphur dioxide emissions. To reduce these emissions, the total solphur content in c~ial product ~must he decreased. This can he accomplished by using low-sulphur coal. cleaning coal prior to combustion. retaining sulphw during wmhustion. or hy treatment of tlur gases after combustion. The...

Introduction Yellow mustard (Sinapis alba L.) is a new multipurpose rotation oilseed crop for Willamette Valley agriculturalists, especially non-irrigated operations. Yellow mustard can also be used to produce condiment mustard, as a green manure crop, and as a biopesticide. Although yellow mustard seed production is relatively new to the Willamette Valley, Oregon’s north-central counties have ...

Commonly cultivated Brassicaceae mustards, namely garlic mustard (Alliaria petiolata), white mustard (Brassica alba), Ethiopian mustard (B. carinata), Asian mustard (B. juncea), oilseed rape (B. napus), black mustard (B. nigra), rapeseed (B. rapa), white ball mustard (Calepina irregularis), ball mustard (Neslia paniculata), treacle mustard (Erysimum repandum), hedge mustard (Sisymbrium officina...

Oxidative scrubbing is used to remove H2S from gas streams. A key problem in regeneration of the absorbent is the removal of fine particles of sulphur from the suspension of the scrubbing liquid. Dispersions of ultra-fine bubbles have been called "colloidal gas aphrons" or aphrons for short. These dispersions have interesting properties and it was found that they have particular advantages in t...

Iron-sulphur clusters are one of the most common types of redox centre in biology. At least six proteins (IscS, IscU, IscA, HscB, HscA and ferredoxin) have been identified as being essential for the biogenesis of iron-sulphur proteins in bacteria. It has been shown that IscS is a cysteine desulphurase that provides sulphur for iron-sulphur clusters, and that IscU is a scaffold for the IscS-medi...

The elemental composition of keratohyalin granules from the interpapillary and papillary lingual epithelium and the oesophageal epithelium of the rat were studied by X-ray microanalysis in an EMMA-4 analytical electron microscope, equipped with an energy dispersive detector. A quantitative assay of the sulphur concentration in keratohyalin granules was performed, using a suitable sulphur standa...

; Studies on the distribution of different fOrulS of sulphur in seven widely occurring soil series representing five great groups viz. Udorthents, Fluvaquents, Dystrochrepts, Hapludalfs and Hapludolls indicated that non sulphate-sulphur, mostly contributed to the total sulphur (86.7%) followed by organic-sulphur (10.0%) and sulphate-sulphur (3.3%). All forms of sulphur had significant positive ...
