purpose : acanthamoeba keratitis (ak) is a sight-threatening corneal infection with a rapidly increased incidence since 1990s along with the growing popularity of contact lenses. in this study we aimed to study patients with ak and its associated risk factors in farabi eye hospital of tehran, focusing on those with more severe corneal involvement. methods : patients with clinical or laboratory ...

Given an integral “stamp” basis Ak with 1 = a1 < a2 < . . . < ak and a positive integer h, we define the h-range n(h, Ak) as n(h, Ak) = max{N ∈ N | n ≤ N =⇒ n = k ∑

In this contribution we investigate the impact of the fluid-air interface on the dissolved electrolyte Potassium hexacyanoferrate K4[Fe(CN)6] by infrared-visible sum-frequency generation spectroscopy (SFG) and surface tension measurements. SFG is a surface specific nonlinear optical technique that records the vibrational spectrum of the adsorbed species with little to no contribution from the b...

In the field of software architecture, a paradigm shift is occurring from describing the outcome of architecting process to describing the Architectural Knowledge (AK) created and used during architecting. Many AK models have been defined to represent domain concepts and their relationships, and they can be used for sharing and reusing AK across organizations, especially in geographically distr...

the aim of this paper is a) if σak2 < ∞ then σak rk(x) is in bmo that{rk(x)} is rademacher system. b) p1k=1 ak!nk (x) 2 bmo; 2k  nk < 2k+1that f!n(x)g is walsh system. c) if jakj < 1k then p1k=1 ak!k(x) 2 bmo.

Adenylate kinase (AK) modulates the interconversion of adenine nucleotides (AMP + adenosine triphosphate----2 ADP). We evaluated the fifth kindred with hereditary erythrocyte (RBC) AK deficiency. The proband had chronic hemolytic anemia. Her RBC had undetectable AK activity when measured spectrophotometrically, whereas those of her parents had half-normal AK activity. AK electrophoresis showed ...

A panel of mutant class II genes have been constructed using site-directed mutagenesis and DNA-mediated gene transfer. Using this technique, Ak beta polypeptides have been altered by substituting one or more Ad beta-specific residues at polymorphic positions in the beta 1 domain. Transfection of M12.C3 B lymphoma cells with most mutant Ak beta* genes results in the expression of Ak beta* Ad alp...

Neben der Funktionalität finden Qualitätsattribute wie Sicherheit, Gebrauchstauglichkeit, Performanz und Zuverlässigkeit in verschiedensten Domänen immer mehr Beachtung. Das Vernachlässigen dieser Qualitäten führt häufig zu gescheiterten Projekten, verlängerter Time To Market und hohem Änderungsaufwand. Wie können jedoch im Requirements Engineering nichtfunktionale Anforderungen effizient erhob...
