Background Nonimmune hydrops fetalis (NIHF) is still a challenging diagnosis. The differential diagnosis is extensive and the success of identifying a cause depends on the thoroughness of efforts to establish a diagnosis. For the early diagnosis of NIHF, a virtual gene panel diagnostic tool was developed. The female premature baby in question was delivered via emergency cesarean at 30 + 1 weeks of gestational age (GA) due to rapidly developing NIHF to a healthy mother. The family history was noncontributory. Methods DNA of the family was extracted and sequenced by the virtual hydrops panel with whole-exome sequencing. Results The hydrops panel revealed Noonan syndrome (NS) with a germline m…

Altitude effect in UV radiation during the Evaluation of the Effects of Elevation and Aerosols on the Ultraviolet Radiation 2002 (VELETA-2002) field …

2008

[1] The Evaluation of the Effects of Elevation and Aerosols on the Ultraviolet Radiation 2002 (VELETA-2002) field campaign was designed to study the influence of aerosols and altitude on solar UV irradiance. The altitude effect (AE) was evaluated for UV irradiance under cloudless conditions by taking spectral and broadband measurements in SE Spain in the summer of 2002 at three nearby sites located at different heights (680 m, 2200 m, and 3398 m). A spectral radiative transfer model (Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART)) was also applied, mainly to evaluate the tropospheric ozone impact on AE. Results are related to the optical properties and air mass origin of the a…

Abstract. Atmospheric concentrations of nitrous acid (HONO), one of the major precursors of the hydroxyl radical (OH) in the troposphere, significantly exceed the values predicted by the assumption of a photostationary state (PSS) during daytime. Therefore, additional sources of HONO were intensively investigated in the last decades. This study presents budget calculations of HONO based on simultaneous measurements of all relevant species, including HONO and OH at two different measurement heights, i.e. 1 m above the ground and about 2 to 3 m above the canopy (24 m above the ground), conducted in a boreal forest environment. We observed mean HONO concentrations of about 6.5 × 108 molecules …

Pratique juridique grecque et économie dans la Calabre post-byzantine (XIIe-XIIIe s.)

2014

Fonti recentemente edite conservate nell'Archivio Ducal de Medinaceli consentono di studiare sotto l'aspetto linguistico, sociale ed economico una zona della Calabria meridionale che nel regno normanno-svevo mantenne una popolazione di lingua rito e diritto privato bizantino. Recently published sources preserved in the Archivio Ducal de Medinaceli allow to study a linguistic, social and economic aspect of an area of ​​southern Calabria that in the Norman-Swabian kingdom maintained a population of rite and Byzantine private language. À partir des nouvelles sources, disponibles suite à la publication des actes privés grecs de l’Archivo Ducal de Medinaceli, on étudie ici la société rurale de l…

Solar angle and sky light effects on ground reflectance measurements in a citrus canopy

1993

Abstract Ground radiometry was used to gather spectral data from different targets of a citrus canopy, in order to analyze the effect of solar zenith angle and proportion of diffuse radiation on spectral reflectance. Results have shown that the variation in solar angle causes significant changes in nadirsensed reflectance from vegetation, which exhibits a marked diurnal pattern with a minimum slightly shifted from the solar noon. This fact is more noticeable in the near-infrared and middle-infrared regions of the spectrum. Furthermore, the visible part of the spectrum has resulted in being highly influenced by the diffuse radiation incident on the canopy, which has been quantified by two di…

A simple model for computing diffuse solar radiation

1989

In this paper a very simple model for predicting the daily diffuse solar radiation at any Italian location using as input few extensively measured meteorological parameters is proposed. In fact the daily diffuse radiation D, MJ.m−2.day−1, here is correlated with only the relative sunshine duration sS and the noon altitude of the sun on the 15th of the month hn, degrees, by the following equation: D=7(sS−(sinhn)1.55 . The validity of this formula is verified using monthly mean daily data from four Italian stations displaced at various latitudes or altitudes or geographical situations (inland or coastal site). The test results show that the deviations between the measured and the computed val…

Validation of a very simple model for computing global solar radiation in the European, African, Asian and North American areas

1990

Abstract In a previous paper Coppolino has proposed a very simple model for predicting the monthly mean daily global solar radiation G (MJm −2 day −1 ) at any Italian location using as input only the sunshine duration s (hours) and the noon altitude of the sun on the 15th of the month h n (degrees). The correlation suggested is G = 7.8 s 0.5 (sin h n ) 1.15 . Herein the validity of this model is verified by extending its application to dat from 24 stations displaced at various latitudes, altitudes above sea level and geographical situations in the European, African, Asian and North American areas. Furthermore the validity of this model to fit the data of the tested stations is compared with…

Constitutions of Site and Visitor at the Swarbrick Wilderness Discovery Site

2013

Located just off the North Walpole Road, the Swarbrick Wilderness Discovery Site can be seen as a node of several different historical trajectories which are – to different extents – documented in the artworks which frame, or decorate, the site. My account draws on my own biography and probes the investments I have in my various post-settler entanglements with the area. I critique, in particular, the idea of ‘wilderness’ as one formative to post-settler narrations and myths at the same time that it places indigenous practices of belonging under erasure. For, most recently, Swarbrick stood metonymically for the campaign to preserve ‘old growth forests’, culminating at the end of the 1990s, a…

A new model for estimating diffuse solar radiation in Italy from clearness index and minimum air mass

1990

The aim of this study is: (a) to propose a new simple model for estimating the monthly mean daily diffuse radiation D, MJ m−2 day−1, using as input only the clearness index Kt and minimum air mass and (b) to develop a map of diffuse solar radiation incident on a horizontal surface in Italy. The correlation herein suggested is D = 5.6 Kt−0.55 (sin hn)1.58 where hn is the noon altitude of the sun on the 15th of the month, in degrees, and Kt = G/H0; G and H0 are the monthly mean daily global and extraterrestrial solar radiation respectively. This equation is applied to Adrano, Palermo, Macerata and Genova stations, provided with measured data of global and diffuse radiation, and the relative c…
