Water samples from Eber and Karamik Lakes were analyzed with ICP (ICP-OES Instrument Spectro Genesis Fee, Germany) equipment to determine the element levels in the water. That impact level of these elements on the distribution of species was discussed. Change in the lake water composition was not a significantly determining factor in the number of species and diversities of water mites. However, eutrophication was observed to be a determining factor on the distribution of species.展开更多

The following species were collected from Karamik Lake in Afyon Province, Turkey between April and August, 2015, Hydryphantes flexiosus, Hydrodroma despiciens, Georgella helvatica, Eylais infundibulifera, Hygrobates nigromacutlatus and Torrenticola brevirostris. These species were separately analyzed by Ultraviolet Spectrophotometer (US) and the results assessed using graphical readings. The affiliations between the species were read from the graphical curves of each species and then compared in terms of the curves.展开更多
The article comprises synthesis of calyx[4]-oxa-crown, and calix[4]-thia-crown compounds containing nitrile groups (3a, 3b) and amino groups (4a, 4b) and their corresponding oxime derivatives (5a, 5b) and liquid-liqui...The article comprises synthesis of calyx[4]-oxa-crown, and calix[4]-thia-crown compounds containing nitrile groups (3a, 3b) and amino groups (4a, 4b) and their corresponding oxime derivatives (5a, 5b) and liquid-liquid extraction studies of these compounds. The oxime derivatives of compounds (5a, 5b) have been synthesized by reacting of di-n-butylamino derivatives of calix[4]-oxa-crown, and calix[4]-thia-crown compounds (4a, 4b) with amphi-chloroglyoxime in methanol-THF. Their cation and anion transfer studies were performed by using liquid-liquid extraction procedure. It has been concluded from the observations that the compound 3a shows a good extraction behavior toward Na+ ion in the presence of other metal cations. Whereas, its oxime derivatives transfers all of the metal cations used in the liquid-liquid extraction studies.展开更多
