steel 2205 is one of the most famous duplex stainless steels. the microstructure of this steel composed of ferrite and austenite in similar amount. therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. it is not possible to employ the usual heat treatment. it shows the importance of ...

Abstract With the massive growth of wireless networks comes a bigger impact collisions and interference, which has negative effect on throughput energy efficiency. To deal with this problem, we propose an in-band collision interference detection scheme based full-duplex technology. study its performance, compare efficiency performance traditional half-duplex symmetric transmissions. Our analysi...

The cis-syn cyclobutane pyrimidine dimer (CPD) is a cytotoxic, mutagenic and carcinogenic DNA photoproduct and is repaired by the nucleotide excision repair (NER) pathway in mammalian cells. The XPC-hHR23B complex as the initiator of global genomic NER binds to sites of certain kinds of DNA damage. Although CPDs are rarely recognized by the XPC-hHR23B complex, the presence of mismatched bases o...

BACKGROUND AND PURPOSE Two surgical trials established that carotid endarterectomy is beneficial to symptomatic patients who have a severe internal carotid artery (ICA) stenosis on angiograms. Duplex ultrasonography-derived hemodynamic parameters show a good correlation with angiography and are often used for detecting severe ICA stenoses. However, duplex performance is ultrasound machine and o...

BACKGROUND AND PURPOSE We compared two-dimensional time-of-flight magnetic resonance angiography (MRA) and duplex ultrasonography with arteriography for the detection of 70% to 99% stenoses at the carotid artery bifurcation (ie, surgical disease according to findings of the North American Carotid Endarterectomy Trial). METHODS Three blinded readers independently measured stenoses on MRA in 73...
