تتناول هذه الدراسة موضوع النشاط الاشعاعي في التربة في بعض مناطق محافظة نینوى من خلال قیاس تراكيز الفعالیة الاشعاعیة للنویدات المشعة في نماذج من التربة تم جمعها من تلك المناطق، وحساب بعض من مؤشرات التلوث الاشعاعي فیها.استخدمنا لهذا الغرض مطیافیة ومنظومة كاشف الجرمانیوم NaI(Tl)(2.5×3.8cm) أشعة كاما مع منظومة الكاشف الومیضي وأجرینا مقارنة بین النتائج التي حصلنا علیها من كلا المنظومتین. ،HPGe عالي النقاوة أن معدل تراكيز النویدات المشعة ، NaI(Tl) بینت النتائج التي حصلنا علیها من منظومة وهي U-238و Th-232وk-40و Ra-226وPb-214 214 في تلك النماذج كان یساوي (41.24و 21.46و326.74و33.55و11.76)Bq/kg على التوالي.

    The book discusses constituent quarks, diquarks, the massive effective gluons and the problem of scalar isoscalar mesons. The quark-gluonium classification of meson states is also given. Experimentally observed properties of hadrons are presented together with the corresponding theoretical interpretation in the framework of the composite hadron structure. ...

    Calabi-Yau spaces are complex spaces with a vanishing first Chern class, or equivalently, with trivial canonical bundle (canonical class). They are used to construct possibly realistic (super)string models and are thus being studied vigorously in the recent physics literature.In the main part of the Book, collected and reviewed are relevant results on (1) several major techniqu...

    There are a number of unanswered questions which indicate that the Standard Model, successful as it is, cannot be the entire story. One solution to answering these questions is that the Standard Model is an effective low-energy theory of structure hopefully nearby in its energy scale in much the same way that a model of strong interactions among nucleons mediated by pions is an...
