A NEW MICROSCOPE ILLUMINATOR

Advantages of a synchrotron bending magnet as the sample illuminator for a wide-field X-ray microscope.

In this paper the choice between bending magnets and insertion devices as sample illuminators for a hard X-ray full-field microscope is investigated. An optimized bending-magnet beamline design is presented. Its imaging speed is very competitive with the performance of similar microscopes installed currently at insertion-device beamlines. The fact that imaging X-ray microscopes can accept a lar...

Darkfield Micromanipulation with an Ultropaque Illuminator Recently

second. The other ciliates studied obviously have a much lower speed of coordinating impulse. These values are so far below the velocities of true neural impulses that it is not possible to consider a "neuromotor" factor in the coordination of these Protozoa. Further investigations are in progress along the lines indicated here and will be reported in detail. The writer is indebted to Dr. W. M....

A new microscope for the kidney: mathematics.

The discovery of the microscope in the late 17th century revealed otherwise invisible processes, and revolutionized biology. Years later, mathematics has the potential to do the same. We will highlight recent studies that utilize computational modeling techniques to investigate kidney function. Like a microscope, mathematical models offer a variety of “magnification levels” that focus on differ...

A New Class and Demonstrating Microscope

1 and 2 is one which lias recently been constructed, at my suggestion, by Mr. Charles Collins, the Optician of Great Tichfield Street ; and may, I think, be found useful by those engaged in teaching microscopic anatomy. The old method of lecturing upon diagrams, and exhibiting specimens under the microscope after lecture,has these two serious objections: ls?,a large number of microscopes must b...
