Improved discrimination of subglacial and periglacial erosion using10Be concentration measurements in subglacial and supraglacial sediment load of th…

2015

Deciphering the complex interplays between climate, uplift and erosion is not straightforward and estimating present-day erosion rates can provide useful insights. Glaciers are thought to be powerful erosional agents, but most published ‘glacial’ erosion rates combine periglacial, subglacial and proglacial erosion processes. Within a glaciated catchment, sediments found in subglacial streams originate either from glacial erosion of substratum or from the rock walls above the glacier that contribute to the supraglacial load. Terrestrial cosmogenic nuclides (TCN) are produced by interactions between cosmic ray particles and element targets at the surface of the Earth, but their concentration …

Fluid-pressure controlled soft-bed deformation sequence beneath the surging Breiðamerkurjökull (Iceland, Little Ice Age).

2009

16 pages; International audience; The general subject of this paper is subglacial deformation beneath Breiðamerkurjökull, a surging Icelandic glacier. More specifically it discusses the evolution and the role of fluid pressure on the behaviour of subglacial sediments during deformation. During Little Ice Age maximum, the two outcrops studied, North Jökulsarlon (N-Jk) and Brennhola-Alda (BA), were located at 2550 m and 550 m respectively from the front of the Breiðamerkurjökull. Sedimentological analysis at the forefield of the glacier shows thick, coarse glaciofluvial deposits interbedded with thin, fine-grained shallow lacustrine/swamp deposits, overlain by a deformed till unit at N-Jk. BA…

3D VIRTUAL CH INTERACTIVE INFORMATION SYSTEMS FOR A SMART WEB BROWSING EXPERIENCE FOR DESKTOP PCS AND MOBILE DEVICES

2018

Abstract. Recently, the diffusion of knowledge on Cultural Heritage (CH) has become an element of primary importance for its valorization. At the same time, the diffusion of surveys based on UAV Unmanned Aerial Vehicles (UAV) technologies and new methods of photogrammetric reconstruction have opened new possibilities for 3D CH representation. Furthermore the recent development of faster and more stable internet connections leads people to increase the use of mobile devices. In the light of all this, the importance of the development of Virtual Reality (VR) environments applied to CH is strategic for the diffusion of knowledge in a smart solution. In particular, the present work shows how, s…

Sharing on web 3D models of ancient theatres. A methodological workflow

2016

Abstract. In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn’t exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describ…

GLOBE BASED 3D GIS SOLUTIONS FOR VIRTUAL HERITAGE

2018

Abstract. During the last years, many solutions have been proposed for 3D Virtual Heritage representations. Recently, also new technologies for online gaming evolved, based on javascript libraries (WebGL), used to create and publish virtual interactive environments. They are based on recent Web browser’s functionalities, surpassing some limitations of VRML technologies. On the side of geospatial information, technology has evolved from desktop GIS to 2D WebGIS and globe applications. The use of globe applications is, today, very diffused due to its immediate and at the same time impressive representation of the earth surface and territories. These technologies have been, also, applied to Vi…

Søren Kierkegaard et les masques de l’autobiographie

2010

Si Søren Kierkegaard, contrairement à Jean – Paul Sartre, n’a pas expressément sacrifié à l’autobiographie, il est cependant indéniable que l’on découvre, à travers son œuvre, des autobiographies déguisées qui prennent diverses formes. Ce phénomène n’est sans doute pas étranger au fait que Kierkegaard accorde non seulement une importance capitale à la notion d’existence mais qu’il considère aussi que sa propre existence est à l’origine de sa réflexion philosophique, voire que seule l’existenc...

Greater Trochanteric Pain Syndrome: What is the Meaning?

2011

Greater trochanteric pain syndrome (GTPS) is a common cause of lower extremity pain. This is frequently attributed to trochanteric bursitis and distension of the subgluteal bursae. Patients are suffering from pain radiating to the posterolateral aspect of the thigh, paraesthesiae in the legs, and tenderness over the iliotibial tract. Often the symptoms are mild, with the patient treating himself successfully through activity modification and other conservative measures. including relative rest, ice, compression, elevation, anti-inflammatory medication and treatment modalities such as ultrasound and electrical stimulation, combined with a structured rehabilitation program. Patients whose sym…

Subglottic stenosis imitating the carina – a case report of airway mimicry

2021

Summary We present a case of awake tracheal intubation with flexible bronchoscopy which resulted in incorrect tracheal tube placement. The presence of a stenotic subglottic lesion with an appearance similar to the carina led to the tube being positioned with only the tip within the trachea whilst the cuff was located between the vocal cords. A capnography trace was identified before induction of anaesthesia; however, visual confirmation of the carina was undertaken in a rushed manner due to the patient becoming agitated. Once the incorrect tracheal tube placement was identified, the decision was made to wake the patient. Thereafter, a more experienced operator successfully performed awake t…

Talsu ezera organogēno nogulumu uzkrāšanās apstākļu izmaiņas holocenā

2017

Bakalaura darba mērķis bija noskaidrot paleoģeogrāfiskos apstākļus kādos uzkrājušies nogulumi Talsu ezera attīstības laikā holocēnā un šo apstākļu izmaiņas, analizējot ezera nogulumus. Talsu ezers atrodas subglaciālā iegultnē kopā ar Vilkmuižas ezeru, blakus arheoloģiski nozīmīgām vietām – Talsu pilskalnam, senajai kuršu mājvietai un Ugunskapiem Vilkmuižas ezerā. Darba izstrādē apkopota informācija par Talsu ezera izcelsmi, reljefa ģeomorfoloģiju un rezultāti no ezera nogulumu apstrādes ar biostratigrāfiskajām un ģeofizikālajām metodēm. Talsu ezers ir vecāks par 7000 gadiem, un savas pastāvēšanas laikā piedzīvojis vismaz 6 ūdens līmeņa izmaiņas, 3 klimata periodus un cilvēku apdzīvojumu tā …
