The observed spectral lags of gamma-ray bursts (GRBs) have been widely used to explore possible violations of Lorentz invariance.However, these studies were generally performed by concentrating on the rough time lag of a single highest-energy photon and ignoring the intrinsic time lag at the source.A new way to test nonbirefringent Lorentz-violatin
This paper reports results from a field experiment established in 1995 and still on going.It is located in Lodi, in the irrigated lowlands of Lombardy, Northern Italy.The experiment compares two rotations: the annual double cropping system, Italian ryegrass + silage maize (R1); and the 6-year rotation, in which three years of double crop Italian ry
The scour at downstream of hydraulic structures is one of the major concern in its stability analysis and operation.The excess energy existing immediately downstream of such structures has to be controlled.Hence, it is NDT Products necessary to design and install a device for dissipating excess energy in order to prevent downstream scour.The drop s
The main Nail Care purpose of this practice paper is to describe and analyse the possibilities and complexities of integrated health care across borders.First, we portray an ideal scenario for this type of care with a case of patients suffering from rheumatoid arthritis and living in the Dutch-Belgian frontier area.It shows how cross border care en
