We describe a method to analyse inclined air showers produced by ultra high energy cosmic rays using an analytical description of the muon densities. We report the results obtained using data from inclined events (60 • < θ < 80 •) recorded by the Haverah Park shower detector for energies above 10 19 eV. Using mass independent knowledge of the UHECR spectrum obtained from vertical air shower mea...

The observation of ultrahigh energy neutrinos (UHEνs) has become a priority in experimental astroparticle physics. UHEνs can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going ν) or in the Earth crust (Earth-skimming ν), producing air showers that can be observed with arrays of detectors at the ground. With the Surface Detector Arra...

Automotive radar systems utilizing the millimeterwave band have been developed 2) since they can detect targets even in bad weather. In the automotive radar systems, linear polarization inclined 45 degrees is utilized in order to avoid mutual radio interference between them. The antenna for the automotive radar systems is required to have high efficiency, which means high gain against for an ap...

In the title compound, C(21)H(24)O(3), the enone group adopts an s-cis conformation. The planes of the aromatic rings are inclined at an angle of 6.1 (1)°. The alk-oxy tail is not linear, with the maximum deviation from the least-squares plane being 0.375 (2) Å. Mol-ecules are connected into extended chains along the a axis through O-H⋯O(carbon-yl) hydrogen bonds and are inter-linked via C-H⋯O ...

The fluctuations of γ ray families simulated with CORSIKA in the energy region 3×1010eV on the basis of standard Lns collider physics exhibits alignments of secondaries in the stratosphere and at ground level. The remarkable event registrated on the Concorde doesn’t fit well however those cases ; The possible hints of new mechanisms, especially the valence diquark breaking, are considered. Obse...

The title compound, C(14)H(12)FNO, crystallizes as the trans phenol-imine tautomer. The two benzene rings are essentially coplanar, being inclined to one another by 9.28 (7)°. This is at least in part due to the intra-molecular O-H⋯N hydrogen bond between the hy-droxy O atom and the imine N atom. The crystal structure is stabilized by an array of weak C-H⋯O and C-H⋯F inter-actions, which link t...

In an effort to discover new potential boron-dipyrromethene (BODIPY) dyes, the title compound, C19H17BF2N4O4, was prepared from 2,4-dimethyl-pyrrole, 3,5-dinitro-benzaldehyde and boron trifluoride in a one-pot reaction. The BODIPY fragment is nearly planar, with a maximum deviation from the least-squares plane of 0.251 (2) Å, and the benzene ring is inclined at a dihedral angle of 86.8 (6)° to ...

Hollow-waveguide slot array antennas [1] have been widely used in the milli-meter band since they do have neither radiation loss nor dielectric loss. Furthermore, they have been developed especially for military application such as radars. For commercial application such as fixed wires access system, mass production at low cost has been required and single layer hollow-waveguide slot array ante...
