Bu çalışmada ilk etapta doğal (H-Zt), kimyasal şartlandırma yapılmış (KOH-Zt) ve sonrası Fe3O4 manyetik nanopartiküller ile yükleme (KOH-Zt/Fe3O4) olmak üzere üç farklı klinoptilolit Cu(II) giderimi konsantrasyon pH’ya bağlı olarak araştırılmıştır. Ardından en iyi verim alınan adsorbent KOH-Zt çalışmalara devam edilerek, temas süresi, başlangıç metal konsantrasyonu, dozajı sıcaklığın etkisi KOH...

Biodiesel industry requires a cheaper and economical viable raw material that can replace the vegetable oil. Waste from animal and plant sources became the main option due the availability and cheap. In this study, coconut waste is used to produce biodiesel using methanol, acid sulfuric and KOH. In situ process is used, where all the catalyst, reagent and raw material is mixed together in one s...

Dehydrohalogenation of 5,6-dihalogen-1,3-dioxepanes II with KOH/MeOH or NaOCH3/MeOH under controlled reaction conditions gave mainly 5-halogen-4,7-dihydro-1,3-dioxepines III. Further substitution of vinylic-bromine in III whit KO-t-Bu/tert-BuOH or KOH/MeOH led to corresponding 5-substituted-4,7-dihydro-1 ,3-dioxepines some of which underwent spontaneous isomerization to 6,7-dihydro-1,3-dioxepin...

Background: One of the key techniques for the preparation of 125I seeds is adsorption of 125I onto silver bits coated by palladium (pd). Carriers played an important role in the adsorption of 125I on palladium. KI is used as a carrier for fixing of 125I onto silver wire bits coated with palladium. Materials and Methods: Three procedures KI, KOH, NH4OH were investigated for adsorption of ...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

Parametrized motion planning algorithms \cite{CFW} have high degree of flexibility and universality, they can work under a variety external conditions, which are viewed as parameters form part the input algorithm. In this paper we analyse parameterized problem in case sphere bundles. Our main results provide upper lower bounds for parametrized topological complexity; typically involve sectional...
