   Sammanfattning : Catalytic reactions on solid surfaces have been studied under Ultra-high vacuum (UHV) conditions for decades. These studies provide crucial information for catalytic reactions, such as surface structures, adsorption sites, and reaction mechanisms. LÄS MER

4. 3. Analyses and Application of Ambient Seismic Noise in Sweden : Source, Interferometry, Tomography

   Författare :Hamzeh Sadeghisorkhani; Ólafur Gudmundsson; Ari Tryggvason; Roland Roberts; Frederik Tilmann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic interferometry; Ambient noise; Surface wave; Wave propagation; Inverse theory; Sweden; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Sammanfattning : Ambient seismic noise from generation to its application for determination of sub-surface velocity structures is analyzed using continuous data recordings from the Swedish National Seismic Network (SNSN). The fundamental aim of the thesis is to investigate the applicability of precise velocity measurements from ambient noise data. LÄS MER

5. 4. Collaborating with Gertrude Stein : Media ecologies, reception, poetics

   Författare :Solveig Daugaard; Tania Ørum; Carin Franzén; Jesper Olsson; Logan Esdale; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; American poetry; Gertrude Stein; media ecologies; reception; poetics; collaborative poetics; media poetics; ambient poetics; Amerikansk poesi; Gertrude Stein; medieekologi; reception; poetik; samarbetspoetik; mediepoetik; ”ambient” poetik;

   Sammanfattning : The reception of the American avant-garde poet, playwright, art collector and salon hostess Gertrude Stein (1874-1946) has to a wide extent taken place in an aesthetic context prior to her work’s academic and hermeneutic canonization. This thesis is in part a mapping of this transmedia reception as it is played out in a North American context in the period from her death and until today, and in part an account of Stein’s particular collaborative poetics, through which her work invites such a reception.

7. 5. New Materials and Improved Ambient Techniques in Mass Spectrometry

   Författare :Nicolò Riboni; Leopold Ilag; Elisa Robotti; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Solid Phase Microextraction; Ambient Mass Spectrometry; Desorption Electrospray Ionization; Paper Spray Ionization; Cavitands; BTEX; New Psychoactive Substances; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Mass spectrometry (MS) is used in several fields, e.g. biology, environmental monitoring, medicine and forensics due to excellent qualitative and quantitative capabilities. The development of new instrumental setups and ionization sources is crucial to analyze a variety of compounds at trace levels. LÄS MER
