Background: Axial spondyloarthritis (axSpA) is clinically characterized by chronic inflammatory back pain and structural changes in the sacroiliac joint (SIJ) as assessed magnetic resonance imaging (MRI). Several studies have reported high rates of bone marrow edema (BME) suggestive SIJ up to 20% individuals general population <45 years. An update definition a positive MRI axSpA for classifi...

This paper proposes a framework of IT portfolio selection and examines the impact of IT synergy on a firm’s IT portfolio selection. IT resources can be distinguished from other forms of resources by their great potential of enhancing synergy between IT units. Based on prior discussion on types of IT synergy, we classify IT synergy into three types and examine the effects of the different types ...

Tij and Delta Hij for stacking of pair i upon j in DNA have been obtained over the range 0.034-0.114 M Na+from high-resolution melting curves of well-behaved synthetic tandemly repeating inserts in recombinant pN/MCS plasmids. Results are consistent with neighbor-pair thermodynamic additivity, where the stability constant, sij , for different domains of length N depend quantitatively on the pro...

The sacroiliac joint (SIJ) is an integral part of both the lumbar spine and the pelvic girdle. It is frequently the source of low back pain and pelvic girdle pain. Recent research has permitted a deeper understanding of its function and assessment. The mechanical assessment of the SIJ as a transmitter of load between trunk and lower limbs, and as a means to absorb torsion stresses of the pelvis...

In this paper, a systematic study on the effects of particle size and hybrid of two different size of silica nanoparticles on the toughening mechanisms of bisphenol-A epoxy was conducted. Nanosilica particles with mean diameter of 17 nm and 65 nm were blended into epoxy system. Probable synergy effects of these two nanoparticles on Young’s modulus and yield strength have been investigated. ...
