    Author : Md Annaduzzaman; Prosun Bhattacharya; Mustafa Ersoz; Joydeep Dutta; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chitosan Biopolymer; Characterization; Biodegradable; Arsenic V ; Uranium VI ; Adsorption; Isotherm; Kinetic model; Chitosan; Biopolymer; Karakterisering; Bionedbrytbar; arsenik V ; uran VI ; Adsorption; Isoterm; Kinetisk modell; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. READ MORE

    Abstract : In recent years, high arsenic (As) levels of about 300 µg/L have been reported around the gold mining areas of Geita and Mara regions within the Lake Victoria basin (LVB) in Tanzania. During a sampling campaign at Geita and Mara, the groundwater and surface water samples revealed the presence of high As concentrations as well as Fe and sulfide. READ MORE

  6. 4. Macroscopic Modeling of Metabolic Reaction Networks and Dynamic Identification of Elementary Flux Modes by Column Generation

    Author : Hildur Æsa Oddsdóttir; Anders Forsgren; Bernhard Palsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolic Network; Optimization; Robust Optimization; Least-squares; Column Generation; Modeling; Algorithm; Elementary Flux Mode; Metabolic Flux Analysis; Chinese Hamster Ovary Cell; Amino Acid Metabolism; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : In this work an intersection between optimization methods and animal cell culture modeling is considered. We present optimization based methods for analyzing and building models of cell culture; models that could be used when designing the environment cells are cultivated in, i.e., medium. READ MORE

  7. 5. On thermodynamic and kinetic constraints in autotrophic metabolism
