    Father Time. I. Does the Cosmic Microwave Background Radiation Provide a Universal Arrow of Time ?

    The existence of a non-thermodynamic arrow of time was demonstrated in a recent paper (Mod.Phys.Lett. A13, 1265 (1998)), in which a model of non-local Quantum Electrodynamics was formulated through the principle of gauge invariance. In this paper we show that the Cosmic Microwave Background Radiation is capable of making every particle of the universe (except those which are not acted upon by an electromagnetic field) follow this arrow of time.Comment: To appear in Mod.Phys.Lett. A. This is a slightly revised version which has been communicated to the EPS-HEP99 Conference at Tampere, Finland (15-21 July 1999) [Abs 12_204

    The present study exploits the information based on concentration of trace elements and minerals in understanding the role/mechanism of action of freeze-dried fruit powder suspended in distilled water of Momordica charantia (family: Cucurbitaceae) in diabetes treatment. Laser-induced break down spectroscopy (LIBS) spectra of plant product was recorded under optimized experimental conditions and analyzed. Several atomic lines such as Na, K, Mg, Ca, Fe, Al, etc. have been observed in the LIBS spectra of the above plant product. The concentrations of these minerals are determined by using calibration-free LIBS method. Correlation between the concentration of these elements/minerals and their defined role in diabetes management was studied in normal as well as diabetic animal model

    Specialized Trial Courts: Concentrating Expertise on Fact

    In the absence of a specialized patent trial court with expertise in fact-finding, the Court of Appeals for the Federal Circuit often reviews de novo the many factual questions that pervade patent law. De novo review of fact by an appellate court is problematic. In the area of patent law, as in other areas of law, there are sound institutional justifications for the conventional division of labor that gives trial courts primary responsibility for questions of law. This Article identifies the problems created by de novo appellate review of fact and argues for the creation of a specialized trial court to which the Federal Circuit would feel compelled to defer on questions of fact. It also discusses how such a court would be designed, focusing on the manner in which trial court judges could use the court-appointed advisors to evaluate competing factual claims
