On the basis of the principle that topological quantum phases arise from the scattering around space-time defects in higher dimensional unification, a geometric model is presented that associates with each quantum phase an element of a transformation group.

Introduction: Hyperalgesia is one of the symptoms of diabetic neuropathy and is considered as a major clinical complaint in these patients which could affect the quality of their life. Since attenuation of hyperalgesia is very important, in the present study the possible analgesic effect of aqueous extract of coriander was investigated in male rats with streptozotocin-induced diabetes using sta...

-We present a derivation of the Berry quantum adiabatic phase using group theory. Our formalism is used to discuss possible manifestations in Atomic Physics and to investigate the new cyclic quantum phase recently introduced by Aliaronov and Anandan. J. Physique 48 (1987) 1401-1406 SEPTEMBRE 1987,

  Abstract  Introduction: Diabetic rats display exaggerated hyperalgesic behavior in response to noxious stimuli that may resemble and model aspects of painful diabetic neuropathy in humans. This study was designed to investigate the effect of Trigonella foenum-graecum (TFG) on formalin-induced nociceptive responses (standard formalin test) in streptozotocin (STZ)-induced diabetic rats.  Method...

Disorder is an unavoidable ingredient of real systems. Spatial disorder generates Griffiths phases (GPs) which, in analogy to critical points, are characterized by a slow relaxation of the order parameter and divergences of quantities such as the susceptibility. However, these singularities appear in an extended region of the parameter space and not just at a (critical) point, i.e., there is ge...

Lipid crystallization is ubiquitous in nature, observed in biological structures as well as in commercial products and applications. In a dehydrated state most of the lipids form well ordered crystals, whereas in an aqueous environment they self-assemble into various crystalline, liquid crystalline or sometimes macroscopically disordered phases. Lipid self-organization extends further to hierar...

for more complex analysers for automated sample processing and plant control. The separation time will continue to decrease; in the past there has been limited interest in fast separations but this could change as automated sample processing is developed. Increasing use of coupled techniques such as GC-GC, liquid chromatography-GC, and supercritical Suid chromatography-GC for the separation of ...

Atmospheric aerosols, comprising organic compounds and inorganic salts, play a key role in air quality and climate. Mounting evidence exists that these particles frequently exhibit phase separation into predominantly organic and aqueous electrolyte-rich phases. As well, the presence of amorphous semi-solid or glassy particle phases has been established. Using the canonical system of ammonium su...

The fluorolytic sol-gel synthesis for binary metal fluorides (AlF₃, CaF₂, MgF₂) has been extended to ternary and quaternary alkaline earth metal fluorides (CaAlF₅, Ca₂AlF₇, LiMgAlF₆). The formation and crystallization of nanoscopic ternary CaAlF₅ and Ca₂AlF₇ sols in ethanol were studied by 19F liquid and solid state NMR (nuclear magnetic resonance) spectroscopy, as well as transmission electron...
