Forkhead-associated (FHA) domains are phosphoprotein-binding modules found in diverse signaling proteins that bind partners phosphorylated on threonine or serine. Kinase-associated protein phosphatase from Arabidopsis employs its FHA domain for negative regulation of receptor-like kinase signaling pathways, which are important in plant development. The solution structure of the free state of ki...

Introduction: Plastination is a unique technique for preservation of biological specimens used for teaching purposes. The protocol of flexible sheet plastination includes fixation, slicing, dehydration, force impregnation, casting, and curing (Hajian, Rabiei, Fatollahpour & Esfandiary, 2008). The procedure is done by using P87 flexible unsaturated polyester resin and provides heavy, gross, frag...

We study the frictional sliding of two ideally incommensurate surfaces with a third incommensurate sheet – a sort of extended lubricant – in between. When the mutual ratios of the three periodicities in this sandwich geometry are chosen to be the golden mean φ = (1 + √ 5)/2, this system is believed to be statically pinned for any choice of system parameters. In the present study we overcome thi...

Anti-silencing function 1 (Asf1) is a highly conserved chaperone of histones H3/H4 that assembles or disassembles chromatin during transcription, replication, and repair. The structure of the globular domain of Asf1 bound to H3/H4 determined by X-ray crystallography to a resolution of 1.7 Angstroms shows how Asf1 binds the H3/H4 heterodimer, enveloping the C terminus of histone H3 and physicall...

Finite element analysis was used to investigate the impact behavior of the foam-cored sandwich shells under the ballistic impact. The ballistic limit, failure mode of the face-sheet and energy absorption of the uniform/graded core were discussed in this paper. Based on the impact phase diagrams, the effects of several factors (i.e. projectile shape and diameter, face-sheet curvature and thickne...

Air-blast loading is a serious threat to military and civil vehicles, buildings, containers, cargo. Applications of sandwich-structured composites have attracted increasing interest in modern lightweight design the construction dynamic regimes due their high resistance against blast ballistic impacts. The functional properties such are determined by interplay face sheet material employed core t...

The metal-polymer hybrid system is widely used in automobile and aviation sector due to its lightweight characteristics. Besides, it has many advantages such as noise reduction damping. Inclusion of these improve the fuel economy, which eventually results dramatic carbon footprint. One important sandwich panels. These are structural members by transportation industries. Joining polymers metals ...
