due to the importance of material classification issue in grinding circuits, the ‎performance of primary and secondary hydrocyclones in grinding circuit of esfordi ‎phosphate plant was investigated by sampling within 7 days from feed, overflow, and ‎underflow‎ of these hydrocyclones. at first, the d80 of above streams samples were calculated by ‎the screening analysis. the results showed ‎that ...

The prototypical prokaryotic potassium channel KcsA alters its pore depending on the ambient potassium; at high potassium, it exists in a conductive form, and at low potassium, it collapses into a nonconductive structure with reduced ion occupancy. We present solid-state NMR studies of KcsA in which we test the hypothesis that an important channel-inactivation process, known as C-type inactivat...

Self-signaling models predict less selfish behavior in a probabilistic giving setting as individuals are expected to invest pro-social identity. However, there is also substantial evidence that people tend exploit situational excuses for choices (for instance, uncertainty) and behave more selfishly. We contrast these two motivations (identity management self-deception) experimentally order test...

BACKGROUND Rapid atrial pacing (RAP) and congestive heart failure (CHF) produce different experimental substrates for atrial fibrillation (AF). We tested the hypothesis that AF maintained by different substrates responds differently to antiarrhythmic-drug therapy. METHODS AND RESULTS The class III antiarrhythmic agent dofetilide was given intravenously at doses of 10 (D10) and 80 (D80) microg...

Bu çalışmada, yatay milli darbeli kırıcıların (HSI) kırma kapasitesinin (Q), regresyon analizleri, yapay sinir ağları (ANN) ve çok değişkenli uyarlamalı analizi (MARS) kullanılarak araştırılmıştır. amaçla, Türkiye'deki çeşitli taş ocaklarında ikincil işlemlerinde kullanılan 32 farklı HSI tipi kırıcı ele alınmıştır. Çeşitli sayısal veriler (rotor genişliği (Rw), rotor çapı (Rd), hızı (Vr), karak...

In this paper, systematic studies are performed to identify the parameters that influence selective separation of actinides from a mixture with lanthanides in small channels. particular, dioxouranium metal ions (UO2+2) binary U(VI)/Er(III) nitric acid solution by an organic TBP/kerosene (Exxsol D80) phase, relevant spent nuclear fuel reprocessing is investigated. The effects such as TBP concent...
