Primary cardiac tumors are considered rarely common tumors. They are
classified into two kinds of tumors: (1) Benign cardiac tumors frequently located
in the left cardiac chambers, mostly common is the Myxoma , which is treated
by complete good ex
cising surgery including excision of the tumor base. (2)
Malignant primary tumors, which prefer the right cardiac chambers, mostly
common are Angiosarcoma and Mesothelioma, whose primary treatment is
nearly complete excision surgery with the help of artificial heart and lung,
followed by chemotherapy and radiotherapy, which seldom prolong the life of
the patient for about three years.
This paper tries to examine the relationship between analogy and the grammatical
rule. Analogy is one of the basic principles and bases of Arabic grammar during times of
rule formation and judging it. Linguists were divided in their attitude to ana
logy, with
some supporting it and others against it. Grammarians were more inclined toward analogy
than compilers, because grammarians’ research was based on the existing similarity
between words, phrases, and style used in speech reported by tellers of what had been said
by the Arabs. They based their rules and origins of analogy on that similarity. Analogists
transliterated some foreign terms, Arabized, and derived new words out of them in a
manner similar to that done with Arabic terms. However, some grammarians went very far
in their excessive use of analogy to the extent that it becomes far removed from linguistic
reality to be a form riddle and guessing, leading to reaction against analogy then against
grammar. Analogy became an end in itself; it overlooked its original purpose; was then
manifested in rule formation of words said spontaneously.
الالتزام الطبيعي يعد التزاما قانونيا ينتج أثرا قانونيا كامل, فهو يتضمن أحد عنصري الالتزام و هو عنصر الواجب و لكنه يفتقر إلى عنصر المسؤولية, و يرجع ذلك على أنه يقع في منزلة وسط بين الواجب الأخلاقي و الالتزام القانوني المدني.
