  1. 1. Microstructure and Gelation Behaviour of High Methoxyl and Low Methoxyl Pectin Gels and their Mixtures

    Author : Caroline E E Löfgren; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rheology; kinetic behaviour; LM pectin; transmission electron microscopy; calcium; microstructure; gel formation; sucrose; HM pectin; pectin mixtures;

    Abstract : The objective of this thesis was to explore the functional behaviour of high methoxyl (HM), low methoxyl (LM) and mixed HM/LM pectin gels of different chemical characteristics with emphasis on microstructure and kinetic rheological behaviour. The rheological properties and the structure of pectin gel networks were investigated for pectins under different sucrose, calcium and pH conditions by the means of oscillatory measurements and transmission electron microscopy (TEM).

  2. 2. The evolutionary history of Geum (Rosaceae, Colurieae) : a study of ancient allopolyploid speciation

    University dissertation from Stockholm : Botaniska institutionen

    Author : Jenny E. E. Smedmark; Birgitta Bremer; Pamela S. Soltis; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geum; Rosaceae; molecular phylogeny; allopolyploidy; morphological evolution; gynoecial development; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Allopolyploid speciation plays an important role in flowering plant evolution. Its contribution to diversity has been suggested to be significant in Geum. READ MORE

  3. 3. Specific surface area of some minerals commonly found in granite

    University dissertation from Stockholm : Botaniska institutionen

    Author : Isabelle E. Dubois; Maria E. Malmström; Bo Strömberg; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Granite; Mineral; Surface area; BET; Sorption; Particle size;

    Abstract : The specific surface area, determined by the BET method, is a parameter often used to scale results of mineral studies of surface reactions in terms of rate and capacity to the field scale. Such extrapolations of results from small-scale laboratory experiments to the field-scale are important within many environmental applications. READ MORE

  4. 4. Benefits of Pharmacometric Model-Based Design and Analysis of Clinical Trials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristin E Karlsson; E Niclas Jonsson; Mats O Karlsson; Anders Grahnén; Michael K Smith; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; model-based analysis; pharmacometrics; modeling; disease progression; NONMEM; SAEM; Importance sampling; repeated time-to-event; RTTCE; RCEpT; NIH stroke scale; Barthel index; internal validation; external validation; study power; study design; PHARMACY; FARMACI; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : Quantitative pharmacokinetic-pharmacodynamic and disease progression models are the core of the science of pharmacometrics which has been identified as one of the strategies that can make drug development more effective. To adequately develop and utilize these models one needs to carefully consider the nature of the data, choice of appropriate estimation methods, model evaluation strategies, and, most importantly, the intended use of the model.

  5. 5. Nitrate stable isotopes and major ions in snow and ice from Svalbard

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Carmen Paulina Vega Riquelme; V. A. Pohjola; R. Pettersson; E. Isaksson; C. E. Bøggild; Kumiko Goto-Azuma; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrate stable isotopes; nitrate; NOx proxies; ice cores; percolation; ion relocation; Svalbard; stabila isotoper av nitrat; nitrat; indikator för kväveoxider; iskärnor; perkolation; joniska omlokalisering; Svalbard; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi;

    Abstract : Increasing atmospheric reactive nitrogen (Nr), as consequence of human activities, has generated accumulation of nitrate (NO3-) in Arctic regions. The Arctic has fragile nitrogen limited ecosystems that can be altered by increases of dry or wet deposition of Nr. READ MORE
