  1. 1. Symplectic Embeddings and results in TDA

    Författare :Alvin Jin; Wojciech Chacholski; Gregory Arone; Henry Adams; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : This thesis is a collection of work under the theme of “applied topology."  The linking idea behind seemingly disjoint fields is the existence of a filtration that one uses to study a space. In turn, given the ubiquitous nature of filtrations, applications range from theoretical fields (e.g. LÄS MER

  2. 2. Statistical Methods in Quantitative Spectroscopy of Solar-Type Stars

    Författare :Alvin Gavel; Andreas Korn; Ulrike Heiter; Coryn Bailer-Jones; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi;

    Sammanfattning : Galactic archaeology is the research field that attempts to reconstruct the history of the Milky Way, using primarily the tools of astrometric studies and chemical studies. The latter in turn uses stellar spectroscopy. LÄS MER

  3. 3. Epigenic regulation and posttranslational modification of human cytochrome P450s : focus on CYP2W1, CYP1A2 and CYP2C18

    Författare :Alvin V Gomez; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The cytochrome P450 superfamily represents a very important group of enzymes that are responsible for the metabolism of drugs as well as of endogenous compounds. Many P450s are genetically polymorphic causing important interindividual variability in P450 expression and activity whereas in some cases the basis for interindividual variation has still not been resolved.

  4. 4. Characterizing the pancreatic "isletome" : 3D optical imaging to study diabetes

    Författare :Max Hahn; Ulf Ahlgren; András Gorzsás; Leif Carlsson; Alvin C. Powers; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D imaging; fluorescence microscopy; 3D image analysis; technique development; diabetes; Islet of Langerhans; Insulin; β-cell mass; pancreas; anatomy; molecular medicine medical sciences ; molekylär medicin medicinska vetenskaper ; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : The pancreas is a specialised multipurpose organ, that can be separated into two major compartments: endocrine and exocrine. The exocrine part makes up the majority of the organ volume and functions to secrete digestive enzymes into the small intestine. LÄS MER

  5. 5. Volatile metabolites from microorganisms in indoor environments : sampling, analysis and identification

    Författare :Anna-Lena Sunesson; Alvin Fox; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorbents; Analysis; Cultivation; Determination; Gas chromatography; Identification; Indicator substances; Indoor air; Mass spectrometry; Metabolites; Microbial volatile organic compounds; Optimization; Sampling; Sick buildings; Thermal desorption; Aspergillus versicolor; Cladosporium cladosporioides; Paecilomyces variotii; Pénicillium commune; Phialophora fastigiata; Streptomyces albidoflavus;

    Sammanfattning : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. LÄS MER
