FORMALDEHİT İLE MODİFİYE EDİLMİŞ İĞDE ÇEKİRDEĞİ KULLANILARAK SULU ÇÖZELTİLERDEN MALAHİT YEŞİLİNİN UZAKLAŞTIRILMASI

In this study, formaldehyde treated upon the colour elaegnus angustifalia seeds for immobilize. The effect of pH of solution, dye concentration, adsorbent dosage and solution temperature were investigated for Adsorption process. The results indicated that the data for adsorption of malachite green onto elaegnus angustifalia seeds fitted well with the Langmuir isotherm model. The adsorption dye dosage capacities for elaegnus angustifalia seeds by Langmuir isotherm were found 28,33 mg.g-1. The equilibrium time was found to be 60 min. for 100 mg.L-1 dye concentrations. The rates of adsorption were found to conform to pseudo-second-order kinetics. Gibbs free energy 3172,19 J, Enthalpy 6396 J.mol-1 and entropy 10,72 J. K-1.mol-1 were determined. Results indicated that elaegnus angustifalia seeds could be used to remove malachite green dye from contaminated.Bu çalışmada, iğde çekirdeği renk immobilizasyonu için formaldehit ile muamele edilerek adsorpsiyon işleminde kullanılmıştır. Adsorpsiyon işlemi üzerine, ortam pH’ı, boyarmadde konsantrasyonu, adsorbent miktarı ve ortam sıcaklığının etkileri ayrı ayrı incelenmiştir. İğde çekirdeği kullanılarak malahit yeşili adsorpsiyonunu için elde edilen verilerin Langmuir izotermine uyduğu tespit edilmiştir. Langmuir izotermine göre maksimum adsorplanan boyarmadde miktarı 28,33 mg.g-1 olarak belirlenmiştir. Adsorpsiyonun dengeye eriştiği süre 100 mg.L-1 için 60 dakika olarak belirlenmiştir. Adsorpsiyon hızının ikinci dereceden kinetik modele uyduğu tespit edilmiştir. Adsorpsiyon Gibbs serbest enerjisi 3172,19 J, Entalpisi 6396 J.mol-1 ve Entropi 10,72 J.K-1.mol-1 olarak belirlenmiştir. Malahit yeşilinin çözeltiden uzaklaştırılmasında iğde çekirdeğinin uygun olduğu tespit edilmiştir

Bilateral Fracture of the Humerus Developing After a Seizure: Case Report

Epilepsy patients face not only the risk of possible trauma experienced during a violent seizure (a fall or striking something, for example), patients using antiepileptic drugs (AEDs) are also at high risk of bone fracture because some medications have an adverse effect on vitamin D metabolism. Described in this article is the case of a 72-year-old patient with generalized epileptic seizures and no history of trauma who experienced ongoing pain in shoulder girdle that was diagnosed as bilateral fracture of humerus with limb tomography

Takayasu Arteritis Presenting with Ischemic Stroke: Two case reports

Takayasu arteritis is a rare vasculitic disease characterized with inflamation of vessels. It commonly results stenosis and dilatations of aort and aortic branches. Ischemic Cerebrovascular Disease is one of the major complications of Takayasu arteritis. In this report we concluded two Takayasu arteritis cases in the light of current data whom presented with ischemic stroke clinical symptoms
