Monte Carlo simulation of the response of ESR dosimeters added with gadolinium exposed to thermal, epithermal and fast neutrons

2009

Abstract Monte Carlo numerical calculations of the response of alanine and ammonium tartrate ESR (electron spin resonance) dosimeters exposed to neutron fields with different energy spectra are reported. Results have been obtained for various gadolinium concentrations inside the dosimeters. Furthermore, in order to simulate the in-phantom response we have carried out calculations by varying the depth of the dosimeter. We have found that a large enhancement is obtained for thermal neutrons, because of the very high capture cross section of gadolinium to thermal neutrons. A good enhancement was obtained for epithermal neutrons, whereas the sensitivity improvement in the case of fast neutron i…

Single-particle characterization of ice-nucleating particles and ice particle residuals sampled by three different techniques

2015

Abstract. In the present work, three different techniques to separate ice-nucleating particles (INPs) as well as ice particle residuals (IPRs) from non-ice-active particles are compared. The Ice Selective Inlet (ISI) and the Ice Counterflow Virtual Impactor (Ice-CVI) sample ice particles from mixed-phase clouds and allow after evaporation in the instrument for the analysis of the residuals. The Fast Ice Nucleus Chamber (FINCH) coupled with the Ice Nuclei Pumped Counterflow Virtual Impactor (IN-PCVI) provides ice-activating conditions to aerosol particles and extracts the activated particles for analysis. The instruments were run during a joint field campaign which took place in January and …

Comparative study of three satellite image time-series decomposition methods for vegetation change detection

2018

International audience; Satellite image time-series (SITS) methods have contributed notably to detection of global change over the last decades, for instance by tracking vegetation changes. Compared with multi-temporal change detection methods, temporally highly resolved SITS methods provide more information in a single analysis, for instance on the type and consistency of change. In particular, SITS decomposition methods show a great potential in extracting various components from non-stationary time series, which allows for an improved interpretation of the temporal variability. Even though many case studies have applied SITS decomposition methods, a systematic comparison of common algori…

Beating Darwin-Bragg losses in lab-based ultrafast x-ray experiments

2017

The use of low temperature thermal detectors for avoiding Darwin-Bragg losses in lab-based ultrafast experiments has begun. An outline of the background of this new development is offered, showing the relevant history and initiative taken by this work. (C) 2017 Author(s).

Podstawowe samowartościowanie - walidacja polskiej wersji skali do pomiaru Core Self-Evaluations

2017

Praca przedstawia walidację polskiej wersji skali do pomiaru podstawowego samowartościowania (Core Self-Evaluations – CSES; Judge, Erez, Bono i Thorensen, 2003). Podstawowe samowartościowanie to poglądy danej osoby, dotyczące jej skuteczności, zdolności, wiary we własne siły i pozytywnego nastawienia do siebie i świata. Koncepcja skali jest konstruktem opartym o indywidualne zmienne dyspozycyjne, często badane w kontekście organizacyjnym. Są to: samoocena, wewnętrzne umiejscowienie kontroli, zgeneralizowana samoskuteczność oraz pozytywna afektywność. Na podstawie danych z pięciu badań przeprowadzonych w latach 2014-2016, na łącznie n=3207 osób, w większości pracujących, udało się potwierdzi…

Augusto Costantino Mussolini: i ricorsi storici delle rivoluzioni tra propaganda e disegni provvidenziali

2016

This research arises by focusing on the parallelism Augustus-Constantine, sug- gested just by the first christian emperor as a key point of his policy and an inspiring principle of his propaganda in the letter to the provincials of Palestine; after matching these two great emperors and authors of disguised revolutions, we deal with the attitudes of those intellectuals, politicians and ideologists who were involved in laying the foundations of propaganda com- municative system of fascism, with the ambitious programs of urban planning transformation, cultural and social renewal and colonial conquests. Both emperors are present as reference models within the mytography of Mussolini: behind the…

The Oculo-auricular Phenomenon in Brain-Stem Disease

1993

The oculo-auricular phenomenon (OAP), as described by Wilson in 1908 [26], consists of bilateral coactivation of external ear muscles during lateral gaze. Two ear muscles are innervated by motoneurons of the medial part of the facial nucleus [9, 25]: the transverse auricular muscle (TAM) (Fig. 1), which adducts and curls the helix of the auricle, and the posterior auricular muscle (Fig. 2), which moves the whole auricle backwards [3, 16, 22].

Le autonomie locali fra le Liberazioni e la Costituente (1943-1947)

2010

Il saggio analizza il concetto di autonomia locale nella sua elaborazione e della esperienza amministrativa in Italia posta in essere dopo la guerra di liberazione nazionale contro il nazi-fascismo. L'A. procede ad una serie di articolate riflessioni sulle variabili oggettivi, riconducibili alle modalità di liquidazione del vecchio apparato istituzionale del regime fascista, e soggettive, relative alla cultura e alla capacità di progettazione politica della nuova classe dirigente attiva dopo l'8 settembre 1943. Sulla scorta degli studi sulle origini del regionalismo italiano, che individuano una relazione stretta fra il concetto di autonomia e la lotta di liberazione nazionale, il saggio an…

Direct subphthalocyanine conjugation to bombesin vs. indirect conjugation to its lipidic nanocarrier

2016

International audience; Bombesin (BBN) was covalently bound to graftable subphthalocyanine (SubPc) or to a cholesterol derivative, a component of a liposome that encapsulates non-graftable SubPc. The latter bioconjugation approach was suitable to address the stability of SubPc and was achieved by copper-free click-chemistry on the outer-face of the liposome. Liposomes were purified (FPLC) and then analyzed in size (outer diameter about 60 nm measured by DLS). In vitro binding studies allowed to determine the IC50 13.9 nM for one component of the liposome, cholesterol, conjugated to BBN. Hence, azido- (or alkynyl-) liposomes give fluorophores with no reactive functional group available on th…
