The sympathetic and pressor responses to exercise are exaggerated in hypertension. Evidence suggests that an overactive exercise pressor reflex (EPR) contributes to this abnormal responsiveness. The mechanisms underlying this EPR overactivity are poorly understood. An increasing body of evidence suggests that aldosterone and excessive salt intake play a role in regulating resting sympathetic ac...

Sucrose and common household sugars (e.g. cane) have been studied as dosemeters for a wide variety of applications. However, previous studies of the post-irradiation time dependence of irradiated sugar did not include an electron paramagnetic resonance (EPR) reference material. This work employs synthetic ruby as an EPR reference material to remove significant spectrometer/environmental influen...

to cope with the urban congestion problem resulted from rapid urbanization some cities are successfully using electronic road pricing policy as a demand management measure. in 1982, hong kong governmenttook initiative to experiment electronic road pricing in hong kong. though, the project outcome reveals that electronic road pricing could bring tremendous economic, social and environmental bene...

Introduction EPR was the first spectroscopic method other than UV/visible spectroscopy to be applied systematically to investigations of the structure and functioning of metalloenzymes. The first such EPR studies of xanthine oxidase were reported in 1959 [l]. Since one reduced state of each of the four redox-active centres in the molecule is EPRactive, there is obviously considerable potential ...

Although the sensitivity and dynamic range of EPR are high, the precision of concentration measurements has often been low. Consequently, EPR spectroscopy has a reputation as a rather nonquantitative method. Interlaboratory comparisons of signal area measurements many years ago yielded very discouraging results (1). Since then there have been important improvements in instrumentation and useful...

Electron paramagnetic resonance (EPR) spectroscopy may be applied to examine interactions of melanin with metal ions and drugs. In this work EPR method was used to examination of changes in free radical system of DOPA-melanin--the model eumelanin after complexing with diamagnetic cadmium(II) ions. Cadmium(II) may affect free radicals in melanin and drugs binding by this polymer, so the knowledg...

In the well known treatment of quantum teleportation, the receiver should convert the state of his EPR particle into the replica of the unknown quantum state by one of four possible unitary transformations. However, the importance of these unitary transformations must be emphasized. We will show in this paper that the receiver can not transform the state of his particle into an exact replica of...

In EPR (electron paramagnetic resonance) spectroscopy, computer simulation and least-squares fitting are essential in extracting quantitative structural and dynamic parameters from experimental spectra.Without numerical methods, this extraction would be restricted to simple systems. This chapter summarizes simulation and fitting methods that have been proposed in the literature and implemented ...
