Human Destiny and the Natural Law in St Maximus the Confessor: A Contribution to Orthodox Christian Humanism

open access: yesModern Theology, EarlyView.
Abstract Orthodox Christian theology in general prides itself on bearing the mantle of patristic thought. Orthodox theological anthropology is no different, often drawing on Greek patristic sources in presenting its vision of the human being. Yet Orthodox anthropology can also broadly be categorized as personalist in ways that are not necessarily so ...

Detection of primary photons in high energy cosmic rays using Cherenkov imaging and surface detectors

open access: yes, 2017
Discovered by Hess during some experiments about air ionization, cosmic rays are constituted by particles coming from the space. In the past, cosmic rays allowed the development of Particle Physics; indeed, thanks to their high energy not achievable in ...

A new Anthropocene aesthetics: Mediating Harman, Morton, and Boysen

open access: yesOrbis Litterarum, EarlyView.
Abstract Practitioners of Object‐Oriented Ontology (OOO) have critiqued the metaphysical assumptions of contemporary poetry, and particularly the position of the lyric speaker. Scholars such as Graham Harman and Timothy Morton have positioned themselves as critics of these lyric sensibilities. In recent years, concerns have risen around their critiques

Updated model of cosmic-ray-induced ionization in the atmosphere (CRAC:CRII_v3): Improved yield function and lookup tables

open access: yesJournal of Space Weather and Space Climate
Cosmic rays, including galactic cosmic rays and solar energetic particles, form the main source of ionization of the low and middle atmosphere, which is important for various chemical and physical effects in the atmosphere.

Photon Propagation as a Probe for Fundamental Physics

open access: yes, 2009
In this thesis we show how light propagation can be used in order to constrain particle physics models beyond the Standard Model. We study in particular the effects of non standard physics on the polarization of cosmic microwave background radiation ...

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

Gamma ray Cerenkov telescope image analysis [PDF]

open access: yes, 1997
The subject of this thesis is ground based gamma ray astronomy using the imaging atmospheric Cerenkov technique. The first two chapters are introductory, and describe the field of gamma ray astronomy, the generation of extensive air showers in the ...
