摘要:
A device for carrying out and/or detecting affinity reactions has at least one surface or boundary surface on which an affinity reaction can take place and at least one polymer which is bonded to said surface. According to the invention, the device is produced by bonding the polymer to the surface in its pure phase, i.e., essentially free of solvents. The polymer is preferably a terminally homo- or heterosubstituted bifunctional polymer, preferably a polyalkylene glycol, especially a polyethylene glycol. The surface can be made up of a metal oxide, especially silicon dioxide. The surface can be activated before the polymer is bonded to it, preferably by introducing functional groups with the help of silanization.

Systems and methods for creating and maintaining a stacked volume using one more volumes or extents of a storage subsystem is disclosed. The systems and methods define a hierarchy of operations and components that process operations. The hierarchy includes plex operations for an entire volume, mapping operations that concatenate volumes and/or extents, plex operation for a volume or extent that is a sub-component of a stacked volume. The hierarchy also includes striping operations that create and maintain storage volume stripes comprising sub-volumes and/or extents. In addition, the hierarchy includes configuration operations that operate directly on a storage volume through a hardware or software volume provider. Together, the hierarchy defined allows a flexible, extensible mechanism to build stacked volumes that provide for increase performance, fault tolerance, and/or aggregate volume size, while elimination volume combinations that can cause performance problems.

The present invention relates to new NOS variants or mutants which contain structural alterations in the site of Akt dependent phosphorylation. The altered NOS proteins or peptides, especially the human eNOS proteins or peptides, Akt proteins or polypeptides and their encoding nucleic acid molecules are useful as gene therapy agents for the treatment of diseases including post angioplasty restenosis, hypertension, atherosclerosis, heart failure, diabetes and diseases with defective angiogenesis. NOS proteins and peptides are also useful in methods of screening for agents which modulate NOS activity.

A diamond saw blade D includes diamond grinding stones 2 attached to the peripheral edge of a circular base plate 1. When a first value obtained through multiplication of the circumferential length of a circle having a diameter equal to the maximum outer diameter of the diamond saw blade D by the maximum thickness t of the circular base plate 1 is compared with a second value which is the total area of end surfaces e of the diamond grinding stones 2, the ratio of the second value to the first value is not less than 0.3 but not greater than 1.0.
摘要:
The following was done in order to mechanically polish a bevel face after bevel finishing without manually polishing and thereby speed up the polishing process and improve uniformity of finishing precision, as well as obtain fashionable eyeglasses: That is, a polishing wheel (1) for polishing a bevel with a bevel polishing groove (83a) the shape of which essentially matches the bevel faces of the finished lens is used. The bevel is polished in two processes using said wheel (1). During the first process, the apex position of the bevel in the finished lens is displaced from the bevel-groove center position of the bevel polishing groove (83a) in the wheel (1) to the concave side of the lens and the polishing allowance on the concave side of the bevel faces is polished. During the second process, the bevel apex position is displaced to the lens convex side so that the bevel apex position of the finished lens and the center position of the bevel-groove in the wheel (1) match and the polishing allowance on the convex side and from the polishing irregularities that remained after the first polishing process is polished.
摘要:
A system for damping oscillations in a structure provides two masses that can be controlled to rotate at the frequency of oscillation of the structure and in opposite directions about axes of rotation transverse to the direction of the oscillations. The masses have individually controllable moments of inertia, and when their moments of inertia are equal a harmonic linear force is generated. The phases of the rotating masses can be individually controlled whereby the direction of the resulting harmonic linear force can be controlled. The moments of inertia can be controlled by shifting their centers of gravity relative to the respective axes of rotation.
