-The chemical and the mineralogical composition of a group of pumiceous tufts associated with recent salic volcanic episodes from Tenerife (Canary Islands) have been studied. The investigation focused on the two main types of pyroclastic deposits of the zone: ash-flows and ash-falls. The samples can be classified chemically as trachytic and phonolitic rocks with an intermediate silica content a...

Since the 1960’s the island Tenerife is characterized by an increasing tourism – about 4.9 mio. accommodate tourists in 2003 – which causes a lasting change of the socio-economic situation and a rural exodus. On account of this development the situation of land cover and land use changed in the same time: Fallow land, land wasting and decreasing settlements are some of the main consequences. Th...

The results of the Tenerife Cosmic Microwave Background (CMB) experiments are presented. These observations cover 5000 and 6500 square degrees on the sky at 10 and 15 GHz respectively centred around Dec.∼ +35. The experiments are sensitive to multipoles l = 10 − 30 which corresponds to the Sachs-Wolfe plateau of the CMB power spectra. The sensitivity of the results are ∼ 31 and ∼ 12 μK at 10 an...

One of the most effective ways of recycling the organic and mineral fractions of sludge from the treatment of domestic wastewater is to compost the sludge with the organic fraction of domestic refuse. In the present study, a compost on a semi-industrial scale was obtained from a mixture of domestic refuse and sewage sludge. The evolution of the different parameters throughout the process was no...

Abstract The small island areas oriented to coastal tourism are highly vulnerable marine storms, given the fluctuation of this economic sector and increase in its exposure due increasing anthropogenic presence on coastline. In context, storms between 1958 2017 studied here most important tourist enclaves Tenerife Gran Canaria, located municipalities Arona Adeje (SW Tenerife) San Bartolomé de Ti...
