Transient thermal analysis during the ascent phase of a balloon-borne payload. Comparison with SUNRISE test flight measurements

The thermal design of stratospheric balloon payloads usually focuses on the cruise phase of the missions, that is, the floating altitude conditions. The ascent phase usually takes between 2 and 4 h, a very small period compared to the duration of the whole mission, which can last up to 4 weeks. However, during this phase payloads are subjected to very harsh conditions due mainly to the convective cooling that occurs as the balloon passes through the cold atmosphere, with minimum temperatures in the tropopause. The aim of this work is to study the thermal behaviour of a payload carried by a long duration balloon during the ascent phase. Its temperature has been calculated as a function of the altitude from sea level to floating conditions. To perform this analysis it has been assumed that the thermal interactions (convection and radiation) depend on the altitude, on the environmental conditions (which in turn depend also on the altitude) and on the temperature of the system itself. The results have been compared with the measurements taken during the SUNRISE test flight, launched in October 2007 by CSBF from Fort Sumner (New Mexico).

A Divine Round Trip: the Literary and Christological Function of the Descent/Ascent Leitmotif in the Gospel of John

The thesis of this dissertation is that the Descent/Ascent Leitmotif, which includes the language of not only descending and ascending, but also going, coming, and being sent, performs a significant literary and christological function in the Gospel of John. The Evangelist's Descent/Ascent Leitmotif becomes the Gospel's organizing principal, drawing together a constellation of verbs and a number of themes, including Jesus-Son's origin, identity, relationship to God, authority, signs and works, life, and glory. In the introductory chapter, after providing a layout of the dissertation, the discussion turns to the spacial dimensions and christological importance of the vertical and horizontal depictions of the descending, ascending, coming, going, and being sent verbs. The focus of chapter two is to explain and illustrate, using a version of the Cinderella story, a method that serves to identify the Leitmotif and the verbs, motifs, and themes the Leitmotif draws within its constellation. This approach, titled a thematic structural method, integrates works from thematic scholars Horst Daemmrich and Eugene Falk with works from literary structural scholars A. J Greimas and Roland Barthes, and is a tool to analyze the influence of the Leitmotif as the Gospel's organizing principal on the relationships between the Leitmotif and numerous themes from which John's Christology emerges. The task of chapter three is to explain the rationale for the selection of the Leitmotif's verbs of descending, ascending, coming, going, and being sent. Chapters four and five investigate how the Evangelist, with the repetition of the Leitmotif, constructs his narrative to tell the story of the historical Jesus and shape the Evangelist's Christology. Additionally, the focus is to analyze the transforming influences of the Descent/Ascent Leitmotif on the themes of Jesus-Son's origin, identity, relationship to the Father, and authority, through his signs and works, life, and glory. The Descent/Ascent Leitmotif depicts a divine round trip, and the emphasis of chapter six is to examine the role of the Leitmotif in Jesus-Son's departure from the world and return to God. The Evangelist's use of the Leitmotif in Jesus' prayer to the Father (John 17) and the promise of the Paraclete are included in this chapter. Due to the Descent/Ascent Leitmotif's inherent spatial overtones, elements related to Jesus' return, including heaven, world, the hour, and his form after his resurrection, are explored from a cosmological and ontological perspective.

The Ascent of EU Environmental Policy: A Case for Unintended Consequences. EDAP 1/2015

This paper aims to explore the issue of unintended consequences as the key underlying theme that explains the incremental integration of policies in the EU, with a particular focus on the issue of environmental protection. The theoretical background of the present research is provided by two of the main schools of thought that, in different historical contexts, have theorized unintended consequences as a relevant interpretative/analytical tool for European integration, namely neo-functionalism and neo-institutionalism. The paper focuses on three distinctive moments of the EU environmental policy: the first steps in the 1970s, the change of regulatory paradigm during the 1990s, and the EU leadership role in global environmental policy. The main argument is that while neo-functionalism can give a convincing account of the initial phases of EU environmental policy, neo-institutionalism offers a persuasive framework to understand the consolidation phases of the policy.
