Investigation of the putative iron reducing capabilities of Lokiarchaeota
(Master thesis, 2015-06-01)Marine subsurface sediments are large and ecologically significant microbial habitats. The archaeal phylum Lokiarchaeota is a group of organisms commonly found in these sediments. Their metabolism is unknown, but based on ... -
Investigation of the p–Σ0 interaction via femtoscopy in pp collisions
(Journal article; Peer reviewed, 2020-06-10)This Letter presents the first direct investigation of the p–Σ0 interaction, using the femtoscopy technique in high-multiplicity pp collisions at √s = 13 TeV measured by the ALICE detector. The Σ0 is reconstructed via the ... -
Investigations of abrupt climate change offshore east Greenland continental margin during marine isotope stages 3 and 5
(Master thesis, 2016-06-01)Paleoclimatic records obtained from western Nordic Seas core GS15-198-38CC (70°N, 17°W) exhibit fluctuating climatic patterns of millennial time scales. Here, foraminifera isotope records used to reconstruct sea surface ... -
Investigations of anisotropic collectivity using multi-particle correlations in pp, p-Pb and Pb-Pb collisions
(Peer reviewed; Journal article, 2017-11)Two- and multi-particle azimuthal correlations have proven to be an excellent tool to probe the properties of the strongly interacting matter created in heavy-ion collisions. Recently, the results obtained for multi-particle ... -
Investigations of anisotropic flow using multiparticle azimuthal correlations in pp, p−Pb, Xe-Xe, and Pb-Pb collisions at the LHC
(Peer reviewed; Journal article, 2019)Measurements of anisotropic flow coefficients ( v n ) and their cross-correlations using two- and multiparticle cumulant methods are reported in collisions of p p at √ s = 13 TeV , p − Pb at a center-of-mass energy per ... -
Investigations of the CEL VNTR by cellular experiments and in silico analyses
(Master thesis, 2023-06-02)Carboxyl ester lipase (CEL) is a digestive enzyme which is secreted by acinar cells in the pancreas and released into the intestines. In addition to the globular domain responsible for lipase activity, CEL contains a ... -
Investigations of the Kaup-Boussinesq model equations for water waves
(Master thesis, 2014-06-02)The Kaup-Boussinesq system is a coupled system of nonlinear partial differential equations which has been derived as a model for surface waves in the context of the Boussinesq scaling, and it has also been derived for an ... -
Investigations of the Modified Navier-Stokes Equations in One Dimension
(Master thesis, 2014-06-02)In this thesis we have investigated the Brenner-Navier-Stoke equations in one spatial dimension. These are a modified version of the Navier-Stokes equations, where the modification relates to a mass diffusion term. This ... -
Investigations on the External Forcings acting on the Convective Boundary Layer during the BLLAST Campaign by the CLASS Model
(Master thesis, 2017-06-20)Using both observed and modelled datasets from the 2011 Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) campaign, the influence of large-scale forcings and surface heterogeneity is investigated for ten out of ... -
In‐Flight Observation of Positron Annihilation by ILDAS
(Peer reviewed; Journal article, 2018-08)We report a 511‐keV photon flux enhancement that was observed inside a thundercloud and is a result of positron annihilation. The observation was made with the In‐flight Lightning Damage Assessment System (ILDAS) on board ... -
Iodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
(Peer reviewed; Journal article, 2013-02-19)Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential ... -
Ion Behaviors in the Reconnection Diffusion Region of a Corrugated Magnetotail Current Sheet
(Journal article; Peer reviewed, 2019)The current sheet structure and ion behaviors in a magnetotail reconnection diffusion region are investigated. The multispacecraft analysis suggests a corrugated current sheet structure, interpreted as due to a flapping ... -
Ion Concentration Influences the Charge Transfer Due to a Water−Air Contact Line Moving over a Hydrophobic Surface: Charge Measurements and Theoretical Models
(Journal article; Peer reviewed, 2023)A metal electrode covered by an inert, hydrophobic polymer surface is dipped into water, and the charge transfer was measured as a function of ion concentration for different chlorides, sulfates, and nitrates. A generic ... -
Ion transporters and osmoregulation in the kidney of teleost fishes as a function of salinity
(Journal article; Peer reviewed, 2021-04-20)Euryhaline teleosts exhibit major changes in renal function as they move between freshwater (FW) and seawater (SW) environments, thus tolerating large fluctuations in salinity. In FW, the kidney excretes large volumes of ... -
Ionization dynamics beyond the dipole approximation induced by the pulse envelope
(Peer reviewed; Journal article, 2016-05)When atoms and molecules are ionized by laser pulses of finite duration and increasingly high intensities, the validity of the much-used dipole approximation, in which the spatial dependence and magnetic component of the ... -
The ionization dynamics of atoms and molecules exposed to short pulses
(Doctoral thesis, 2013-08-29)The electrons ejected in an ionization event initiated by an incident laser pulse carry detailed information about the structure and the correlation intrinsic to atoms and molecules. This information is essential for our ... -
