abstract background: despite advances in the field of intravenous therapy, phlebitis is still a common complication of peripheral venous catheter and finding an appropriate solution to prevent and reduce the incidence of this complication remains challenging. one of the methods used in reducing the incidence of phlebitis is the use of saline lock, which is forgotten in most hospitals. therefore...
In a microwave background polarization map that covers only part of the sky, it is impossible to separate the E and B components perfectly. This difficulty in general makes it more difficult to detect the B component in a data set. Any polarization map can be separated in a unique way into " pure E, " " pure B, " and " ambiguous " components. Power that resides in the pure E (B) component is gu...
The DRY motif with the highly conserved R3.50 is a hallmark of family A G protein-coupled receptors (GPCRs). The crystal structure of rhodopsin revealed a salt bridge between R135(3.50) and another conserved residue, E247(6.30), in helix 6. This ionic lock was shown to maintain rhodopsin in its inactive state. Thus far, little information is available on how interruption of this ionic bond affe...
In future microwave background polarization experiments, particularly those that aim to characterize the B component, careful attention will have to be paid to the mixing of E and B components due to finite sky coverage and pixelization. Any polarization map can be decomposed into “pure E,” “pure B,” and “ambiguous” components. In practice, since the B component is expected to be much weaker th...
We report a search for the flavor-changing neutral current decay B → Xsl +l− using a 29.5 fb−1 data sample accumulated at the Υ(4S) resonance with Belle detector at the KEKB e+e− storage ring. We observe evidence for B → Kμ+μ− and report the preliminary branching fraction of B(B → Kμ+μ−) = (0.99 −0.32 +0.13 −0.15)× 10−6. We also set the following 90% confidence level upper limits on the branchi...
فرض کنیم[0،1) ? ? و e یک فضای باناخ و (x, d) یک فضای متریک موضعا فشرده باشد وlip0(x، e) فضای توابع لیپ شیتس کوچک e- باناخ مقدار تعریف شده بر فضای متریک هولدر موضعا فشرده( x , d^? )باشد که در بی نهایت صفر می شوند. در این پایان نامه نشان می دهیم، هر دوسویی خطی دوجداساز t:lip0(x,e) ? lip0(y,f)یک عملگر ترکیبی وزن دار به صورت t(f(y))=h(y)(f(p(y))), (f ?lip0(x,e), y ? y) است که در آن به ازای هر...

Background: Lipoprotein abnormalities have been identified among the several risk factors that could account for increases the risk of CVD in diabetes. Abnormal status of B-group and antioxidant vitamins in diabetes may illustrate the benefits of these vitamins supplementation on modification of lipid profiles. Methods: As a randomized double blind placebo controlled clinical trial, 110 type 2...
P opular magazines often describe cryptography products in terms of algorithms and key lengths. These security techniques make good headlines. They can be explained in a few words and they’re easy to compare with one another. We’ve seen statements like “128-bit keys mean strong security, while 40-bit keys are weak” or “triple-DES is much stronger than single DES” or even “2,048-bit RSA is bette...
