Viscoelasticity and Birefringence of Low Birefringent Polyesters [PDF]
Polymer Journal, 2000 Dynamic viscoelasticity and dynamic birefringence were investigated for a series of polyesters with various combinations of dimethyl decalin 2,6-carboxylate, DMHN and dimethyl terephthalate, DMT as acid component and 9,9-bis[4-(2-hydroxy-ethoxy)phenyl]fluorene, BPEF and ethylene glycol, EG as diol component.

Effect of pH, ethanol concentration, and temperature on detection of quagga mussel (Dreissena bugensis) birefringence [PDF]
Management of Biological Invasions, 2013 In the western United States, federal, state, and local agencies have engaged in extensive efforts to detect the presence of larval dreissenid mussels (veligers) in water bodies before such a presence becomes a full-scale infestation.

BIREFRINGENT ELECTROWEAK DEFECTS [PDF]
International Journal of Modern Physics A, 2002 In this paper we examine the propagation of electromagnetic waves through electroweak textures and W-strings. The photon is associated with a negative mass squared term as a consequence of its coupling to the intermediate vector bosons from which the electroweak defect is constructed.

Stress Analysis of Polarization Maintaining Optical Fibers by the Finite Element Method
International Islamic University Malaysia Engineering Journal, 2012 Stress-induced birefringence in single mode polarization maintaining optical fibers has been investigated using the finite element method. The modal birefringence caused by external forces in the Panda and the Side Tunnel fibers are calculated.
