the interaction of sodium n-dodecyl sulphate (sds) with histones in phosphate buffer ph 6.4 has been studied spectroscopically and by equilibrium dialysis. the enthalpies of interaction and the spectroscopic data suggest different structural stability for histones-sds interaction. the linear relation between enthaly and absorbtion was determined by the equation of m= , where m is the stability ...

The main purpose of the present work is to investigate the impact of soil-structure interaction on performance-based design optimization of steel moment resisting frame (MRF) structures. To this end, the seismic performance of optimally designed MRFs with rigid supports is compared with that of the optimal designs with a flexible base in the context of performance-based design. Two efficient me...

the interaction between nano-sio2 and lysozyme was investigated by the method of uv-visible  detection and fluorescence spectroscopic techniques. the thermal denaturation of lysozyme has been investigated in the presence and absence of nano-sio2 over the temperature range (293-373) k in different buffers and ph values, using temperature scanning spectroscopy. the presence of nano-sio2 caused th...

A structural equation modeling approach is used to build understanding of the Biggs 3P model of teaching and learning within the tertiary institution sector. A learning quality dependent construct is used to show the Biggs 3P construct blocks do display significant two way interactions between each and every construct, and so act as an interlinked system.

Although they might not agree with the precise terms of Moreno’s statement, most contemporary structural analysts would still subscribe to the view that visual images continue to play a key role in both exploring and presenting the patterns displayed by structural data. Among the many kinds of structural patterns that have been explored and presented visually, one stands out. Structural analyst...

cylindrical concrete tanks are commonly used in wastewater treatment plants. these are usually clarifier tanks. design codes of practice provide methods to calculate design forces in the wall and raft of such tanks. these methods neglect self-weight of tank material and assume extreme, namely ‘fixed’ and ‘hinged’ conditions for the wall bottom. however, when founded on deformable soil, the actu...

background: aneurysm is a blood-filled bulge in the wall of vessels that occurred in abdominal aortic and cerebral vessels. the dilation of artery leads to aneurysm. methods: three dimensional modelling was utilized for a patient with cerebral aneurysm and a normal subject, and additional fluid-structural interaction simulation was performed. we consider pulsatile blood velocity as inlet, and b...
