  1. 1. Solute transport in the integrated soil-groundwater system

    Detta är en avhandling från Institutionen för anläggning och miljö

    Författare :Eva Simic; KTH.; [2001]
    Nyckelord :solute transport; groundwater transport; integrated soil.groundwater system;

    Sammanfattning : A Lagrangian stochastic travel time approach has been usedfor investigating dominant process impacts on (non-reactive andreactive) solute transport in the integrated soil-groundwatersystem. A first step has also been taken to extending thisLagrangian stochastic travel time approach to integrate thesoil-groundwater-stream transport through a catchment. LÄS MER

  2. 2. Solute Transport Across Scales Time Series Analyses of Water Quality Responses to Quantify Retention and Attenuation Mechanisms in Watersheds

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Joakim Riml; KTH.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solute transport modeling; Transient storage; Tracer test; Central temporal moments; Spectral analysis; Parameterization;

    Sammanfattning : The intra-continental movement of waterborne contaminants is governed by the distribution of solute load in the landscape along with the characteristics and distribution of the hydrological pathways that transport the solutes. An understanding of the processes affecting the transport and fate of the contaminants is crucial for assessments of solute concentrations and their environmental effect on downstream recipients.

  3. 3. The Lagrangian Stochastic Advective-Reactive Approach to Modeling Solute Transport in Hydrological Systems

    Detta är en avhandling från Institutionen för anläggning och miljö

    Författare :Archana Gupta; KTH.; [2000]
    Nyckelord :solute transport; groundwater transport; unsaturated zone; stream hydrology; stream networks; stochastic processes; mass transfer kinetics; preferential flow; temporal moments; catchment hydrology; Lagrangian transport model;

    Sammanfattning : The Lagrangian stochastic advective-reactive modelingapproach has been used for analyzing transport of bothnonreactive and reactive solutes in different hydrologicalsystems (structured soil, groundwater, mining waste rockdeposits and surface waters including single stream and networkof streams) and at different spatio-temporal scales (rangingfrom laboratory column-scale to catchment-scale). Further, afirst step has been taken to extending the Lagrangianstochastic advective-reactive modeling methodology to integratethe soil-groundwater-stream transport through a catchment. LÄS MER

  4. 4. Effect of Hyporheic Exchange on Conservative and Reactive Solute Transport in Streams Model Assessments Based on Tracer Tests

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Karin Jonsson; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; conservative; hyporheic exchange; model; reactive; retention; solute; sorption kinetics; stream transport; temporal moments; tracer experiment; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : Understanding of the processes affecting solute transport in flowing water is important for the possibility to predict the evolution with time of polluted stream systems. This thesis presents tracer experiment methodology and model developments for solute transport in streams, with special focus on retention processes and their effect on solute stream transport.

  5. 5. Atypical Solute Carriers Identification, evolutionary conservation, structure and histology of novel membrane-bound transporters

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Emelie Perland; Uppsala universitet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Major facilitator superfamily; solute carrier; transporter; protein expression; mRNA expression; phylogenetic clustering; orthologues; co-expression; subcellular location; nutrition.; Neuroscience; Neurovetenskap;

    Sammanfattning : Solute carriers (SLCs) constitute the largest family of membrane-bound transporter proteins in humans, and they convey transport of nutrients, ions, drugs and waste over cellular membranes via facilitative diffusion, co-transport or exchange. Several SLCs are associated with diseases and their location in membranes and specific substrate transport makes them excellent as drug targets. LÄS MER
