In the present paper, by considering the notion of ideals in $MV$-algebras, we study some kinds of ideals in $MV$-algebras and obtain some results on them. For example, we present definition of ultra ideal in $MV$-algebras, and we get some results on it. In fact, by definition of ultra ideals, we present new conditions to have prime ideals, positive implicative ideals and maximal ideals in $MV$...

الأهداف: هدفت الدراسة الحالية الى التعرف على فاعلية النموذج التعليمي (SSCS )في تحسين التفكير التأملي في الرياضيات لدى طلبة الصف العاشر. المنهجية: استخدامت المنهج شبه التجريبي بقياس قبلي و بعدي وتكونت عينة من(40) طالبة وزعوا بالتساوي مجموعتي الضابطة والتجريبية، ولتحقيق أهداف تم بناء اختبار بمهاراته الخمسة (التأمل والملاخظة،الكشف عن المغالطات، الوصول استنتاجات، إعطاء تفسيرات مقنعة، وضع حلول مقترح...

Measles virus (MV) hemagglutinin (MV-H) and fusion (MV-F) proteins induce plaque reduction neutralizing (PRN) antibodies and cell-mediated immune responses that protect against clinical measles. DNA vaccines that encode MV-H and MV-F are being investigated as a new generation of measles vaccine to protect infants too young to receive currently licensed attenuated measles vaccines. However, it i...

The present paper is a sequel to Paoli F, Ledda A, Giuntini R, Freytes H (On some properties of QMV algebras and √′QMV algebras, submitted). We provide two representation results for quasi-MV algebras in terms of MV algebras enriched with additional structure; we investigate the lattices of subvarieties and subquasivarieties of quasi-MV algebras; we show that quasi-MV algebras, as well as carte...
