More than 200 kg real waste electrical and electronic equipment (WEEE) shredder residues from a German dismantling plant were treated at 650 °C in demonstration scale thermochemical conversion plant. The focus within this work was the generation, purification, analysis of pyrolysis oil. Subsequent filtration fractional distillation combined to yield basic chemicals high purity. By means distill...

Ribulose-1,5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39) from Rhodospirillum rubrum has been crystallized in a form that is suitable for structural studies by x-ray diffraction. The asymmetric unit of the crystal contains one dimeric enzyme molecule of molecular mass 101,000 Da. The enzyme was activated prior to crystallization and is presumed to be in the CO2-activated state in the crysta...

wheat (triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. recently, wild barley (hordeum spontaneum) population has increased in wheat fields of many provinces of iran. since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...

Fish farming is increasingly dependent on plant commodities as a source of feed leading to an increased risk for pesticide residues in aquaculture diets and consequently their transfer into aquaculture food products. The European pesticide regulation requires fish metabolism and fish feeding studies where residues in fish feed exceed 0.1 mg kg(-1) of the total diet (dry weight basis) to enable ...
