دراسة ملحمة «علی بساط الریح» الرائعة
الملحمة فن لم یتحدّث العرب القدامی عنه ولم یعرفوا قواعده وأصوله ولم یعطوا وجوده وعیاً صحیحاً، فلذلک یخلو الأدب العربی القدیم من الروائع الملحمیة البارزة، بما فی الکلمة من المعنی العلمی الدقیق؛ بل هناک ما یضاهی الملاحم، والتی یمکن العثور علیها فی العصور القدیمة للأدب العربی. أما فی الأدب الحدیث، فنجد شعراء بارزین أنشدوا ملاحم تاریخیة علی منهج قدیم، کأحمد شوقی وبولس سلامه وعمر أبو ریشة ولکنّ ملاحمهم ...
متن کاملCi-FoxA-a is the earliest zygotic determinant of the ascidian anterior ectoderm and directly activates Ci-sFRP1/5.
This work focuses on the anteroposterior patterning of the ectoderm in the invertebrate chordate Ciona intestinalis. Previous work indicated that, by the eight-cell stage, the anterior and posterior animal blastomeres have acquired different properties, including a differential responsiveness to inducing signals from the underlying mesendoderm. Here, we investigated the molecular basis of this ...
متن کاملQuotients of CI-Groups are CI-Groups
We show that a quotient group of a CI-group with respect to (di)graphs is a CI-group with respect to (di)graphs. In [1,2], Babai and Frankl provided strong constraints on which finite groups could be CI-groups with respect to graphs. As a tool in this program, they proved [1, Lemma 3.5] that a quotient group G/N of a CI-group G with respect to graphs is a CI-group with respect to graphs provide...
متن کاملFrom demagnetizing to magnetizing interactions in CoFe–AgCu granular films
CoFe–AgCu granular films of compositions ranging from 0.17–0.44 ferromagnetic atomic concentration were prepared by rf sputtering. The microstructure and the transport and magnetic properties suggested that this family of samples can be classified into two groups with a crossover concentration at about 32 at. %. The experimental results for samples Co34Fe8Ag54Cu4 and Co18Fe8Ag70Cu4, which are r...
