به دلیل عوارض غیر قابل جبران توکسوپلاسموزیس در افراد دچار نقص سیستم ایمنی و نوزادان متولد شده از مادران آلوده، نیاز مبرم به تکنیک های سریع، حساس و دقیق برای شناسایی توکسوپلاسما گوندی احساس می شود. روش های مولکولی به عنوان روش های حساس تر و اختصاصی-تر از رو ش های سرولوژیک در تشخیص توکسوپلاسموزیس مطرح هستند. در این مطالعه، استفاده از روش real-time nasba برای سنجش کمی بار انگلی در خون ر ت های آلو...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
The eigenvalues of a graph is the root of its characteristic polynomial. A fullerene F is a 3- connected graphs with entirely 12 pentagonal faces and n/2 -10 hexagonal faces, where n is the number of vertices of F. In this paper we investigate the eigenvalues of a class of fullerene graphs.
