Euroopan unionin yleisen tietosuoja-asetuksen aiheuttamat muutokset organisaatioiden tietoturvapolitiikkoihin
2017
EU:n yleistä tietosuoja-asetusta aletaan soveltaa toukokuun 25. päivänä 2018 ja sen aiheuttamat muutokset ovat merkittäviä ja kunnianhimoisia. Se on yksi laaja-alaisimpia EU:n lakimuutoksia viimevuosien ajalta. Yleisen tietosuoja-asetuksen vaikutukset ovat merkittäviä organisaatioille, sillä epäonnistuessaan asetuksen vaatimusten noudattamisessa organisaatio joutuu maksamaan merkittävät sakot, korkeimmillaan joko 4% yrityksen globaalista vuosittaisesta liikevaihdosta tai 20 000 000 euroa riippuen siitä, kumpi on korkeampi. Yleinen tietosuoja-asetus tulee luultavasti vaikuttamaan tietoturvapoliitikkojen kehitykseen, kun yritykset pyrkivät noudattamaan uusia vaatimuksia. Tietotu…
Modelling the Impacts of Wildfire on Ash Thickness in a Short‐Term Period
2013
Ash can provide valuable soil protection. However, ash is also very mobile, and soil protection patterns can be quickly changed, favouring the protection of some areas and exposing others with implications for soil erosion. In this research, the effects of a high severity wildfire on ash thickness were studied, 1 and 15 days after the fire. For this evaluation, several interpolation methods were tested to identify the best spatial predictor of ash distribution. The results showed that 1 day after the fire, ash was thinner in high severity areas. Fifteen days after the fire, ash thickness decreased, and the spatial pattern changed. This implies that evaluation of fire severity based on ash t…
Combined TL and 10B-alanine ESR dosimetry for BNCT
2004
The dosimetric technique described in this paper is based on electron spin resonance (ESR) detectors using an alanine-boric compound acid enriched with 1 0 B, and beryllium oxide thermoluminescent (TL) detectors; with this combined dosimetry, it is possible to discriminate the doses due to thermal neutrons and gamma radiation in a mixed field. Irradiations were carried out inside the thermal column of a TRIGA MARK II water-pool-type research nuclear reactor, also used for Boron Neutron Capture therapy (BNCT) applications, with thermal neutron fluence from 10 9 to 10 1 4 n t h cm - 2 . The ESR dosemeters using the alanine-boron compound indicated ESR signals about 30-fold stronger than those…
Alanine blends for ESR measurements of thermal neutron fluence in a mixed radiation field
2007
In this paper, the results of a study on the electron spin resonance (ESR) dosimetry to measure thermal neutron fluence in a mixed radiation field (neutron and photons) are presented. The ESR responses of alanine dosemeters with different additives are compared. In particular, the (10)B-acid boric and the Gd-oxide were chosen to enhance the sensitivity of alanine dosemeters to thermal neutrons. Irradiations were carried out inside the thermal column of the TAPIRO reactor of the ENEA center, Casaccia Rome. The main results are a greater neutron sensitivity and a smaller lowest detectable fluence for the dosemeters with gadolinium than for dosemeters of alanine with (10)B, which is well known…
Inorganic nanomaterials in the aquatic environment: behavior, toxicity, and interaction with environmental elements
2016
AbstractThe aim of this paper is to present characteristics, toxicity and environmental behavior of nanoparticles (NPs) (silver, copper, gold, zinc oxide, titanium dioxide, iron oxide) that most frequently occur in consumer products. In addition, NPs are addressed as the new aquatic environmental pollutant of the 21stcentury. NPs are adsorbed onto particles in the aquatic systems (clay minerals, fulvic and humic acids), or they can adsorb environmental pollutants (heavy metal ions, organic compounds). Nanosilver (nAg) is released from consumer products into the aquatic environment. It can threaten aquatic organisms with high toxicity. Interestingly, copper nanoparticles (Cu-NPs) demonstrate…
EPR DOSIMETRY IN A MIXED NEUTRON AND GAMMA RADIATION FIELD
2004
Suitability of Electron Paramagnetic Resonance (EPR) spectroscopy for criticality dosimetry was evaluated for tooth enamel, mannose and alanine pellets during the 'international intercomparison of criticality dosimetry techniques' at the SILENE reactor held in Valduc in June 2002, France. These three materials were irradiated in neutron and gamma-ray fields of various relative intensities and spectral distributions in order to evaluate their neutron sensitivity. The neutron response was found to be around 10% for tooth enamel, 45% for mannose and between 40 and 90% for alanine pellets according their type. According to the IAEA recommendations on the early estimate of criticality accident a…
Nitrous oxide emissions in a membrane bioreactor treating saline wastewater contaminated by hydrocarbons
2016
The joint effect of wastewater salinity and hydrocarbons on nitrous oxide emission was investigated. The membrane bioreactor pilot plant was operated with two phases: i. biomass acclimation by increasing salinity from 10 gNaCl L−1 to 20 gNaCl L−1 (Phase I); ii. hydrocarbons dosing at 20 mg L−1 with a constant salt concentration of 20 gNaCl L−1 (Phase II). The Phase I revealed a relationship between nitrous oxide emissions and salinity. During the end of the Phase I, the activity of nitrifiers started to recover, indicating a partial acclimatization. During the Phase II, the hydrocarbon shock induced a temporary inhibition of the biomass with the suppression of nitrous oxide emissions. The r…
Determination of toxic elements by cathodic-stripping-voltammetry
1981
The DPCSV determination of arsenic, selenium and tellurium in the sub-ng/ml range is discussed. After electrolytic deposition of the elements as intermetallic compounds with copper on the electrode surface, the determination is carried out by cathodic stripping. The simultaneous determination of selenium and tellurium or of selenium and arsenic is possible. Problems which occur in the application of these methods are discussed.

Respingimenti a catena e tutela cautelare del diritto d’asilo. Le ordinanze del Tribunale di Roma sulle ‘riammissioni informali’ in Slovenia
2021
On the 3rd of May, the Rome Tribunal accepted the complaint lodged by the Ministry of Interior against the interim measure with which, last January, the same Court declared the illegitimacy of the procedure of migrants and asylum seekers informal readmission in Slovenia, because of the violation inter alia of the principle of non-refoulement. Despite the negative outcome for the asylum seekers, the order of the complaint did not refute the reasoning of the judge of the first instance who, for the first time, recognized the entry protection by issuing an urgent precautionary measure. This contribution focuses on the recent tendency of States’ national Courts to provide protection, including …
