We present the first µSR measurements ever performed on elemental Pu, and set the most stringent upper limits to date on the magnitude of the ordered moment µ ord in α-Pu and δ-stabilized Pu (alloyed with 4.3 at. % Ga). Assuming a nominal hyperfine coupling field of 1 kOe/µB we find µ ord ≤ 10 −3 µB at T ∼ = 4 K.

The experimental vibrational circular dichroism, electronic circular dichroism, and optical rotatory dispersion spectra and corresponding quantum chemical predictions of 3,3'-diphenyl-[2,2'-binaphthalene]-1,1'-diol (VANOL) are used to confirm its absolute configuration as (+)(589)-(aR) or (-)(589)-(aS). A discrepancy in the literature crystal structure has been resolved by determining the X-ray...

When the SH groups of various derivatives of human haemoglobin are converted into their mercuric mercaptides small changes are observed in the optical rotatory dispersion in the range 385-294mmu. These changes are proportionately greater for the reactive than for the unreactive SH groups. These observations have been interpreted in terms of the conformational changes that are likely to occur in...

The optical signals degrade as travel down the optical link due to the optical fiber properties such as chromatic dispersion, polarization mode dispersion, polarization dependent loss, polarization dependent gain and various fiber nonlinear effects, which are considered as limitations in the high-speed, lang-haul fiber communication systems. Where chromatic dispersion causes different wavelengt...

Fiber-optic communication systems are light wave systems that employ optical fibers for information transmission to increase several orders of magnitude the bit rate distance product. However the performance of optical fiber communication system is limited by fiber dispersion. Dispersion compensation is the most important and challenging aspect of the optical fiber communication to maintain a h...

This paper review of the chromatic dispersion compensation in optical fiber communication system. In optical communication system to compensate dispersion Fiber Bragg grating (FBG) is one amongst the applicable and necessary components. During this the appliance of chirped FBG was studied as a dispersion compensator in optical communication systems. This paper studied the various types of simul...

Single optical fibres exhibiting minimum dispersion over the two optical wavelength windows of 1300 and 1550 nm region are essential for the multi-channel operation of dense wavelength multiplexed systems and networks. Design guidelines of dispersion-flattened optical fibres, over a wide band of optical spectrum, which have a triple-clad or segmented-core distribution of stepindex regions are d...

A dispersion-managed optical system with step-wise periodical variation of dispersion is studied in a strong dispersion map limit in the framework of path-averaged Gabitov-Turitsyn equation. The soliton solution is obtained by iterating the pathaveraged equation analytically and numerically. An efficient numerical algorithm for obtaining of DM soliton shape is developed. The envelope of soliton...

-In modern optical fiber communication systems, dispersion and nonlinear effect of optical fiber are the two main factors of decreasing communication quality, especially in Group Velocity Dispersion (GVD). In this paper, we use single-mode transmission fiber, Dispersion Compensation Fiber (DCF) and erbium-doped fiber amplifier (EDFA) to design a dispersion compensation optical fiber communicati...

The optical rotatory properties of a myeloma globulin, immunoglobulin G (IgG), and a normal individual IgG in the far ultraviolet were investigated by rotatory dispersion, circular dichroism, and absorption spectroscopy. The optical rotatory dispersion of the myeloma immunoglobulin displayed two peaks, one at 205 ml* and the other at 210 rnp, and a trough at 228 mp, a lesser one at 230 mp, and ...
