  2. 11. Towards more selective sorbents for extraction of drugs and biomarkers from biological fluids using molecularly imprinted polymers

    Author : Mohammad Mahdi Moein; Mohamed Abdel-Rehim; Milton L. Lee; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted polymer; sol-gel; solid phase extraction; microextraction by packed sorbent; monolithic column; Analytical Chemistry; analytisk kemi;

    Abstract : Sample preparation has a critical role as a first step in analytical processes, especially in bioanalysis and environmental analysis. A good sample preparation technique should be robust and stable, regardless of the sample matrix. READ MORE

  4. 12. Dynamical Analysis of Chemical Activity of Sterically Encumbered Lewis acid/base Pairs

    Author : Maoping Pu; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This licentiate thesis is about the dynamics analysis of chemical reactions involving a stoichiometric mixture of sterically hindered Lewis base (LB) and Lewis acid (LA) – the so-called frustrated Lewis pairs (FLPs). The tool for dynamical description of chemical reactions is the ab initio molecular dynamics (AIMD) simulations together with the calculation of minimum energy paths (MEPs) on the potential energy surfaces (PESs).

  5. 13. Adaptation of Salmonella enterica to antibiotics and innate immunity effectors

    Author : Kim Vestö; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Salmonella enterica is a bacterial pathogen causing major morbidity and mortality in low- and middle-income countries. The bacteria can cause a wide range of disease, ranging from the severe systemic disease typhoid fever to localized gastroenteritis. Characteristics of typhoid fever, caused by Salmonella enterica serovar Typhi (S. READ MORE

  6. 14. New Materials and Improved Ambient Techniques in Mass Spectrometry

    Author : Nicolò Riboni; Leopold Ilag; Elisa Robotti; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 15. Moments of lobbying : an ethnographic study of meetings between lobbyists and politicians

    Author : Camilla Nothhaft; Göran Eriksson; Mats Eriksson; Øyvind Ihlen; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; lobbying; Brussels; communication; interaction; shadowing; ethnography; strategies; organizing principles; impression management; relations; Media and Communication Studies; Medie- och kommunikationsvetenskap;

    Abstract : The aim of this study is to define and further the understanding of the practice of lobbying as it manifests in the participants’ interactions with each other and to identify its specific conditions (rules, standards, traits).A research overview shows that lobbying as a political phenomenon is well researched, but that the action per se tends to been taken for granted as ‘talking’.
