Abstract

In a method for testing a continuously forward-moving strand a light beam which passes along a plane that extends approximately perpendicularly to the longitudinal axis of the strand is introduced into the strand. The brightness value is measured on a place of the strand exterior which is distal from the light incidence place by means of at least one photoelectronic element disposed directly on the strand exterior and the measured result is evaluated in a gating circuit which is electrically connected to the photoelectronic element.

Multilayers are enabling new science with x-ray free electron lasers

Journal Article Bajt, S ; Chapman, H N - SPIE Newsroom, N/A, N/A, September 10, 2007, N/A

Newly developed multilayer-based mirrors and optical elements enable the imaging of high-resolution structure and ultrafast dynamics of samples with the soft X-ray free electron laser, FLASH, at DESY in Hamburg. The FLASH free-electron laser (FEL) produces intense ultrashort soft X-ray pulses with more than 10{sup 8} times higher peak brightness as compared with the most advanced synchrotron radiation sources. This allows time-resolved X-ray imaging and holography of nanostructures with a temporal resolution approaching 10 fs, opening up new studies of laser-matter interactions and the dynamics of correlated systems. In addition, the ultrafast pulses can be used to obtain structural datamore »« less

Solar heated canteen

Patent Stowell, D E

This patent describes an apparatus for confining a supply of water and enabling the water to be heated by solar radiation. The apparatus comprises: (a) a water-confining vessel having a panel of spherically rounded contour convexly directed outwardly from the vessel and centered upon an axis perpendicular to the vessel, an opposed lower panel, a boundary of circular configuration joining the upper and lower panels, and a sealable spout communicating with the interior of the vessel, (b) a jacket of self-supporting thermally insulative material, and comprised of (1) a bottom wall of circular perimeter adapted to lie in abutment withmore »« less
Advances in recording scattered light changes in crustacean nerve with electrical activation

Conference Carter, K M ; Rector, D M ; Martinez, A T ; ...

We investigated optical changes associated with crustacean nerve stimulation using birefringent and large angle scattered light. Improved detection schemes disclosed high temporal structure of the optical signals and allowed further investigations of biophysical mechanisms responsible for such changes. Most studies of physiological activity in neuronal tissue use techniques that measure the electrical behavior or ionic permeability of the nerve, such as voltage or ion sensitive dyes injected into cells, or invasive electric recording apparatus. While these techniques provide high resolution, they are detrimental to tissue and do not easily lend themselves to clinical applications in humans. Electrical and chemical componentsmore »« less

Experimental results of neutron fluence outside an iron shield in the forward direction

Conference Torres, M M.C. ; Elwyn, A J ; Fein, D ; ...

Analyses of both lateral shielding measurements and Monte Carlo calculations for beam stop geometry for incident hadrons at energies between 10 GeV and 10 TeV suggests that the dose equivalent can be represented by the expression H = H{sub 0}(E)e{sup -r/{lambda}}/r{sup 2} where H, is the source term, r is the radial distance to the point of interest in the shield, and {lambda} is the effective interaction length, or absorption mean free path. However, unlike the lateral shielding case, there is no similarly simple analytical expression that can be used to describe the on-axis longitudinal cascade development. In this studymore »« less

Method and apparatus for fringe-scanning chromosome analysis

Patent Norgren, R M ; Gray, J W ; Hirschfeld, T B

A method is described for determining the longitudinal morphology of oblong microscopic particles, each oblong microscopic particle having a longitudinal axis. The method consists of the steps of: (a) suspending the oblong microscopic particles in a carrier fluid; (b) constraining the oblong particles to sequentially flow along a flow path which is substantially the same for every oblong microscopic particle and in which the longitudinal axis of each oblong microscopic particle is oriented to be substantially parallel to the flow path; (c) generating a fringe intensity pattern, the fringe intensity pattern having a plurality of fringes, each being disposed substantiallymore »« less
