شناسایی خانواده ایرانی دارای فنوتیپ Rh null
چکیده سابقه و هدف سیستم گروه خون Rh یکی از پیچیده‌ترین سیستمهای گروههای خونی و دارای حدود 50 آنتی ژن است. دو ژن Rh D و Rh CE مسئول کد کردن آنتی‌ژن‌های سیستمRh هستند. فنوتیپ Rh null قادر به عرضه هیچ یک از این آنتیژنها نیست و شیوع آن یک در شش میلیون نفر است. می‌توان با تعیین فنوتیپ سایر افراد خانواده، خون مناسب را در موارد مورد نیاز تهیه کرد. مورد در سال 1392 خانمی 39 ساله با گروه A منف...
متن کاملA New Method of Mobile Robot Navigation: Shortest Null Space
In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...
متن کاملDomination Null and Packing Null Vertices
A vertex v of a graph G is domination null in G if g(v) = 0 for every minimum fractional dominating function g on G. Packing nullity is defined analogously, with reference to fractional closed neighborhood packings. We give classes of examples and examine graph operations that produce or preserve such vertices; several open problems are posed.
متن کاملThe Null Content of Null Case
While we agree that the base-generated phonologically null nominal known as PRO has Case, we dispute the recent contention of Chomsky & Lasnik (1995) and Martin(2001) that there is a special Null Case, assigned in English by certain instances of infinitival to. We show that, contrary to Martin’s claims, there is no consistent distinction between instances of to that license PRO, and instances o...
متن کاملNull Steering GPS Array in the Presence of Mutual Coupling
A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...
