Europe’s offshore winds assessed from SAR, ASCAT and WRF

2019

Abstract. Europe’s offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of Synthetic Aperture Radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced SCATterometer (ASCAT) ocean wind maps. The wind statistics at 10m and 100m height using an extrapolation procedure involving simulated long-term stability over oceans is presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid resolution with data every 30 minutes during 30 years f…

ALCUNE CONSIDERAZIONI SULL’ARCHITETTURA CIVILE A SIRACUSA E NEGLI IBLEI FRA XV E XVI SECOLO

2021

The few buildings that survived the 1693 earthquake, concentrated mainly in the city of Syracuse, offer a fragmentary picture of late Gothic civil architecture in south-eastern Sicily. The analysis of the detail elements such as windows and doorawys in the facades, stairways and loggias inside the courtyards, marked by the coexistence of late Gothic and Renaissance architectural languages, highlights the adoption of decorative motifs widespread throughout Sicily and the Mediterranean context. However, many original solutions emerge, such as the square mullioned window, largely common in the city of Syracuse but also present in Scicli, probably very common in the urban landscape of the hybla…

Biomonitoring with cryptogams near the power station of la Robla (Leon, Spain)

2007

The present monitoring study was undertaken to analyze the impact of atmospheric pollution on the lichens found near a power station in northern Spain. Data from 565 releves gathered on 113 sites were analyzed. In areas near the power station the lichen species belong to the Xanthorion community. In areas away from the power station and that are not under the influence of dominant winds, the lichenic diversity increases and the species present belong to the Parmelion community. In intermediate areas between the two, there is a great increase in lichen diversity, in these areas there is a replacement of the species that typically belong to the Xanthorion community, by species typical of the …

Impairment of Temporal Binding Window in Migraine Patients

Retrieval of characteristic parameters for water vapour transmittance in the development of ground based Sun-Sky radiometric measurements of columnar…

2014

Abstract. Sun–sky radiometers are instruments created for aerosol study, but they can measure in the water vapour absorption band allowing the estimation of columnar water vapour in clear sky simultaneously with aerosol characteristics, with high temporal resolution. A new methodology is presented for estimating calibration parameters (i.e. characteristic parameters of the atmospheric transmittance and solar calibration constant) directly from the sun–sky radiometer measurements. The methodology is based on the hypothesis that characteristic parameters of the atmospheric transmittance are dependent on vertical profiles of pressure, temperature and moisture occurring at each site of measurem…

Precipitable water vapour content from ESR/SKYNET sun-sky radiometers: validation against GNSS/GPS and AERONET over three different sites in Europe

2018

The estimation of the precipitable water vapour content (W) with high temporal and spatial resolution is of great interest to both meteorological and climatological studies. Several methodologies based on remote sensing techniques have been recently developed in order to obtain accurate and frequent measurements of this atmospheric parameter. Among them, the relative low cost and easy deployment of sun–sky radiometers, or sun photometers, operating in several international networks, allowed the development of automatic estimations of W from these instruments with high temporal resolution. However, the great problem of this methodology is the estimation of the sun-photometric calibration par…

Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi

2012

L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…

The new world of biosimilars: what diabetologists need to know about biosimilar insulins

2010

Biosimilar pharmaceuticals are emerging as patent protection on the original biopharmaceutical products expires. However, biopharmaceuticals are particularly complex molecules, and biosimilar insulins present special challenges. In part this reflects their structure and chemical modification after synthesis to attain a biologically active form. Their therapeutic window is narrow and the accuracy of their dosing is highly dependent on the formulation and quality of the administration device. For these reasons, the European Medicines Agency has issued stringent guidelines that must be fulfilled in order to receive approval as a biosimilar soluble insulin. Prescribers should therefore consider…

Land Surface Temperature Retrieval Methods From Landsat-8 Thermal Infrared Sensor Data

2014

The importance of land surface temperature (LST) retrieved from high to medium spatial resolution remote sensing data for many environmental studies, particularly the applications related to water resources management over agricultural sites, was a key factor for the final decision of including a thermal infrared (TIR) instrument on board the Landsat Data Continuity Mission or Landsat-8. This new TIR sensor (TIRS) includes two TIR bands in the atmospheric window between 10 and 12 $\mu\hbox{m}$ , thus allowing the application of split-window (SW) algorithms in addition to single-channel (SC) algorithms or direct inversions of the radiative transfer equation used in previous sensors on board …
