Vacuum polarization and non-Newtonian gravitation
Gell-Mann and Low have emphasized that, as first pointed out by Uehling and Serber, vacuum polarization effects produce a logarithmic modification to the Coulomb potential at small distances. I point out here ...

A Soft X-Ray Study of the Large Magellanic Cloud
A survey of the Large Magellanic Cloud (LMC) has been carried out with the imaging X-ray telescope aboard the Einstein Observatory. Ninety-seven sources were detected. On statistical grounds, we estimate that les...

Flavor symmetry in two body decays of bottom mesons
Dominant decays of bottom mesons into two pseudoscalars are studied in the framework of the six-quark model of the weak interactions of Kobayashi and Maskawa. Some simpleSU (3) relations between the amplitudes ar...

Current measurements of the gravitational «Constant» as a function of the mass separation
A number of works has now been completed in an effort to check on my earlier work showing a variation of the gravitational constant with mass separation. The precise null experiment of Speroet al. turns out to be...

Stimulated raman scattering up to 10 orders in an optical fiber
This paper describes the experimental investigation of stimulated Raman scattering obtained from a multimode fiber. 10 orders of stimulated Stokes scattering of wavelengths in the 546–702 nm region were obtain...

An X-Ray Survey of Supernova Remnants in the Large Magellanic Cloud
The last supernova (SN) observed in the Galaxy occurred ~375 years ago and it is clear that progress in SN research would be glacial at best if we were limited to the study of galactic events. Although the fir...

Research on Intensity Distribution of Multi-Order SRS in an Optical Fiber
This paper presents a theoretical analysis as well as an experimental investigation on the relative intensities of multi-order stimulated Raman scattering (SRS) in an optical fiber. Our analysis shows that the...

The Effect of Additives for Accelerating Radiation Grafting: The Use of the Technique for Modification of Polymers Especially Polyolefins
Radiation grafting is a convenient one-step method for modifying the properties of polymers1,2. Both ultraviolet light3–7 and ionizing radiation8–12 are useful initiators for the process, however the latter metho...

Compilation Caledonian Metamorphic Map of Ireland
The Caledonian metamorphic rocks of Ireland occur in a series of inliers (Fig. 1), and for this reason a well-defined pattern of metamorphic zonation is not seen as clearly as elsewhere in the Caledonides. The...

Solid-State Laser Sources for Remote Sensing
Remote sensing with laser sources has made tremendous strides during the past decade. The progress has been paced, however, by the slow development of the high power, narrow bandwidth, tunable laser sources re...

Detailed X-Ray Observations of the Cygnus Loop
High quality X-ray spectral and imaging observations of the Cygnus Loop have been obtained with three different instruments. The High Resolution Imager (HRI) on the Einstein Observatory was used to obtain arcseco...

Optical Studies of Supernova Remnants in the Magellanic Clouds
Optical identifications of 32 X-ray sources in the Magellanic Clouds confirm that they are SNRs. They are separated into four classes: the evolved, the oxygen-rich, the Balmer-dominated and the Crab-like. High...

The X-Ray Properties of Supernova Remnants in the Large Magellanic Cloud
There are at least 25 supernova remnants (SNR) in the Large Magellanic Cloud (LMC) with X-ray luminosities exceeding 2 × 1035 erg s-1. As many as 25 other SNR may be contained in the X-ray survey conducted with t...

Optical Observations of Four Balmer-Dominated Supernova Remnants in the Large Magellanic Cloud
We report the optical identification of four Balmer-dominated supernova remnants (SNRs) in the Large Magellanic Cloud. Both the Balmer-dominated spectra and the presence of a broad Ha component in one remnant ...

Biochemical Approaches to Monitoring Human Populations for Germinal Mutation rates: I. Electrophoresis
The advent of relatively inexpensive and convenient techniques for identifying genetic variants of proteins on the basis of differences in molecular charge, thermostability, or, for enzymes, activity has opene...

Optical counterpart of the radio event accompanying the 3B flare of 13 May 1981
Excepting intermittent type III activity, all the radio events over the frequency range 8–8000 MHz accompanying the initial stage of the 3B flare of 13 May, 1981 had their onset in a 2-min interval immediately...

Stop** power ofK electrons for relativistic incident electrons
The contribution of the relativistic effects on the stop** power ofK electrons has been investigated for fast incident electrons. Due to the domination of the transverse and spin-flip effects over the longitudi...
