samples of crushed and cooked canola seeds (okapy double zero) were extracted using supercritical carbon dioxide (scco2) at 34 mpa and 40ºc and a commercial organic solvent (aw406). the oil solubility in scco2 was determined and extracted oils were examined with respect to their chlorophyll contents, nonsaponifiable matters, fatty acid composition and iodine value. the yield of scco2 extraction...

Identifikácia organických látok v slovenskom hnedom uhlí Vzorky slovenského hnedého uhlia z lokality Cígeľ a Handlová boli podrobené nadkritickej fluidnej extrakcii (SFE) oxidom uhličitým, modifikovaným 5 % metanolom. Extrakty, získané metódou SFE, boli podrobené plynovej chromatografii s hmotnostno-spektrometrickou identifikáciou (GC MS). Porovnaním s literárnymi údajmi hmotnostnej spektroskop...

Introduction Conclusions References

The aim of this study was to describe the breeding sites of Culicoides species in Konya province, Turkey. The samples taken from 11 different habitats in Konya province were examined for Culicoides species. The collected adult Culicoides specimens were reared in plastic buckets in our laboratory. Among 2,798 specimens reared, 18 species were identified. Culicoides circumscriptus Kieffer, 1918 w...

From its beginnings, organic chemistry has been a partner to biology, often crossing the artificial boundary between the sciences to the benefit of both disciplines. This is even reflected in the use of the adjective “organic” to refer to the chemistry of carbon. As the field has matured, it has continued to address matters of structure and synthesis to increasingly encompass the grand challeng...

This study investigated the effects of soluble organic matters on membrane fouling characteristics, using silt density index (SDI) and modified fouling index (MFI) to evaluate the fouling potential. Experimental results demonstrated that humic acid had significant effects on membrane fouling indexes. When its concentration was in the range of 0.01-0.05 mg/L, the SDI(15) and MFI were 2.9-3.9 and...

In recent year large amount of water and wastewater generated from various industries and produce organic matters and contaminated the water, this organic this organic compound in water poses serious problems to public health as well as environment. The advanced oxidation process (AOPs) is one of the advanced treatment method for wastewater remediation. In AOPs, ElectroFenton process (EFP) is o...
