Büchi’s theorem, in establishing the equivalence between languages definable in S1S over pP,ăq and the ω-regular languages also demonstrated that S1S over pP,ăq is no more expressive than its existential fragment. It is also easy to see that S1S over pP,ăq is equi-expressive with S1S over pP, sq. However, it is not immediately obvious whether it is possible to adapt Büchi’s argument to establis...
An occupation restricted multiple active space (ORMAS) study of clusters that represent the silicon(100) surface (up to nine surface dimers) is discussed. The accuracy of three different active orbital ORMAS partition schemes for Si(100) surface clusters are compared. In addition to ORMAS-SCF calculations, generalized valence bond-perfect pairing (GVB-PP) properties are generated for comparison...
Results of a twelve-year (1987-1998) prospective study of Visceral Leishmaniasis in 103 patients admitted to the Ahari Children's Hospital Medical Center indicate that IFA (Indirect immunofluorescence antibody test) is highly specific and cheap. Finally we found that 86 patients (84%) were IFA positive and bone marrow aspiration of 34 (79%) of these patients were negative. 59 cases had positive...

هدف از انجام این پروژه استفاده از لاستیک بازیافتی(rtr) برای تهیه ترموپلاستیک الاستومرهای پخت شده بر پایه پلی پروپیلن(pp) بود. با توجه به نقش نانوذرات خاک رس در بهبود خواص فیزیکی- مکانیکی، تاثیر حضور نانو ذرات خاک رس بر خواص مکانیکی این ترموپلاستیک الاستومر برای اولین بار مورد بررسی قرار گرفت. در این مطالعه همچنین تاثیر افزودن لاستیک نو(لاستیک طبیعی(nr)، اتیلن پروپیلن دی ان مونومر) بر خواص مکانی...
