It has been known for some time that stimulation of heterotrimeric G protein-coupled receptors can cause cytoskeletal reorganization. A recent report in Developmental Cell (Lowry et al., 2002) demonstrates that the activation of a tyros...

The use of conjugated dendrimers as a novel molecular architecture for organic LEDs is investigated. Control of colour is demonstrated using materials based on a porphyrin, anthracene and distyrylbenzene core with stilbene dendrons. The...

A rigorous nonlinear stability result for a thermoconvective ferrofluid in a porous medium is derived. The inertia effect is included to Air Max 90 Canada accommodate high velocity flow. The mathematical emphasis is on how to control th...

In this study the two main paradigms for looking at the design activity are compared in terms of their ability to describe the industrtial design process. Special interest is paid to how close these descriptions are to capturing the des...

Phenylalanine ammonia-lyase (PAL) activity increased rapidly on exposure of leaf disks to light. The activity increase was necessary to permit the high rates of flavonoid synthesis in leaf disks and was correlated with the rates of synt...

1. 1. A fluorometric assay for serum xanthine oxidase activity that could be used as a back-up to current tests in the differential diagnosis of acute liver damage is Air Max 95 described. 2. 2. High levels of serum xanthine oxid...

We show that defect melting is closely related to SO(3) lattice gauge theory. The phase transition of this system corresponds to a Lindemann melting parameter L≈50γ where γ≈2 is a parameter characterizing the unharmonic content in...

A finite-difference technique is used to calculate the die swell of a Newtonian liquid emerging from a capillary at zero Reynolds number. There is semi-quantitative agreement with experimental results. The experimental die swell is 13·...

An n-dimensional (convex) polytope is said to have few vertices if their number does not exceed n + 3. Similarly, a simplicial n-sphere with few vertices would not contain more than n + 4 of them. We want to show that all such spheres a...

Image sensors have been made with PIN layers of amorphous hydrogenated silicon on glass covered with transparent conductor constituted by 16 sensor cells of individual access. Attempting to enlarge scale integration, matrix structure an...
