Anatomiczny spektakl w dawnej poezji erotycznej
2016
Artykuł stanowi próbę deskrypcji dawnych zabiegów medycznych, takich jak sekcja zwłok, w kontekście kulturowo-literackiego wydarzenia popularnego w XVI- i XVII-wiecznej Europie. W tekście przywołano genezę padewskich spotkań o charakterze theatrum anatomicum, z dokładnym opisem najważniejszych rytuałów, procedur oraz okoliczności w ich organizowaniu. Autorka, korzystając z bogatego studium Anny Wieczorkiewicz Muzeum ludzkich ciał oraz szkiców autorstwa Radosława Grześkowiaka zatytułowanych Amor Curiosus. Szkice o osobliwych tematach dawnej poezji erotycznej, buduje swój wywód na użytej w tych pozycjach naukowych nazwie „spektakl anatomiczny”. Pozwala to na zgłębienie dychotomii sensu tychże…
BROILER CHICKENS AND THEIR HEALTH STATUS IN FARM: WINE WASTE, AN ADDED VALUE ON FEEDING
2023
Various key economic sectors of the National and Sicilian economy, in addition to contributing to the economic growth also cause a considerable production of waste which today are a problem both for companies then for the environment. For this reason, there is considerable interest in this waste and in the possibility of their reuse to extract bioactive molecules with added value, all in accordance with the objectives of the Blue Economy. In this regard, it has already been demonstrated that from the production waste of various economic sectors it is possible to obtain bioactive molecules with anticancer, antimicrobial, cosmetic, antioxidant and nutraceutical properties (Mauro et al., 2022)…
Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing
2022
In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs. The aim of this work focuses on optimizing the offloading decision, full/half-duplex energy harvesting mode and energ…
The XENON1T Dark Matter Experiment
2017
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented. © 2017, The Author(s).
Search for Light Dark Matter Interactions Enhanced by the Migdal Effect or Bremsstrahlung in XENON1T.
2019
Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c2, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c2 by looking for electronic recoils induced by the Migdal effect and bremsstrahlung us…
XPS structural data and correlation with Mossbauer spectra for Tin-organic compounds: adducts of RnSnCl4-n with 1,2-bis(diphenylphosphino)ethane
1982
Abstract Core level X-ray photoelectron spectra of 1:1 adducts of SnCl4 and RSnCl3 with DPE {[RnSnCl4−n} · DPE (n = 1, R = Me, Bun, Octn, Phn; n = 2, R = Ph; DPE = 1,2-bis(diphenylphosphino)ethane], have been measured in solid phase. The Sn3d 5 2 binding energies, corrected for the Madelung potential at the metal atom, are well correlated with both partial atomic charge on tin, accounting for relaxation upon ionization, and 119Sn Mossbauer isomer shifts. The results are discussed in terms of these molecular parameters.

From disaster to development : parliamentary debate analysis: Atomausstieg and securitization
2017
Tutkimukseni tehtävänä on selvittää, mitä turvallisuusargumentteja käytettiin Saksan parlamentaarisissa debateissa, jotka koskivat atomivoimasta luopumista vuonna 2011 maaliskuusta kesäkuuhun, jolloin keskustelu oli vilkkainta. Alkupäivämäärä määräytyi Fukushiman ydinonnettomuuden mukaan ja loppupäivämäärän määritteli hetki, jolloin Saksan parlamentti, Bundestag, hyväksyi uusia lakeja liittyen ydinenergian käyttöön ja rajoittamiseen. Ydinenergian käytön rajoittamiseen ja poistamiseen viitataan termillä Atomausstieg. Taustoitan työtä keskustelemalla ensin parlamentaarisista debateista yleensä, sitten turvallistamisesta ja energiaturvallisuudesta. Aineistossani viittaukset Fukushiman ydinonne…
