Tourism is considered a strong betting sector, not only for its ability to bring life spaces that were once almost abandoned, but also rethink and remake old traditions, making it an enriching tourist experience, preserving valuing historical, cultural, environmental resources, generating wealth employment. development has been affected by the evolution of society various tourism markets. For t...

Using the four Cluster spacecraft, we have determined the three-dimensional wave-vector spectra of fluctuating magnetic fields in the solar wind. Three different solar wind intervals of Cluster data are investigated for this purpose, representing three different spatial scales: 10 000 km, 1000 km, and 100 km. The spectra are determined using the wave telescope technique (k-filtering technique) ...

-A Fourier spectrometer of the Michelson interferometer variety has been constructed for the study of the far infrared solar spectrum through the stratosphere at resolutions down to 0.5 cm-1. Details of the design, construction and performance of this balloon-borne system, both optical and electronic, are given. The instrument was first flown during August 1965. Despite some difficulties, the i...

Parameter lists are presented for speculative muon colliders at center-of-mass energies of 10 TeV and 100 TeV. The technological advances required to achieve the given parameters are itemized and discussed, and a discussion is given of the design goals and constraints. An important constraint for multi-TeV muon colliders is the need to minimize neutrino radiation from the collider ring.

Millimeter-wave and far-infrared frequencies (f > 100 GHz) remain one of the most underdeveloped frequency ranges, even though there are great numbers of potential applications in remote sensing, spectroscopy, plasma diagnostics, and communications. This is because the millimeter wave and far-infrared frequency range falls between two other frequency ranges in which conventional semiconductor d...

Average amplitude spectra are presented for large radiation impulses from the initial stage of 15 cloud-to-ground (CG) and 36 intracloud (IC) lightning discharges. The spectra are obtained by Fourier transformation of the time domain records of lightning radiation fields with wide bandwidth devices. The field records include the electric field change ∆E (bandwidth 0 –500 kHz), the electric fiel...
