  1. 1. Hg concentration in humus soils in different Arctic and Subarctic tundra vegetation types : Including a method comparison for analyzing metals in humus soils

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Alice Sandvärn; [2022]
    Keywords : Hg concentration; vegetation types; Arctic tundra; elevation gradient; XRF;

    Abstract : Heavy metals, such as mercury (Hg), have a long residence time in the atmosphere and can be transported long distances and deposited in the Arctic via wet and dry deposition. Still, there are few studies on the complex mercury cycle and how different plant groups absorb Hg. READ MORE

  2. 2. Toward prototyping metabolic pathways in cyanobacteria using cell extracts

    University essay from KTH/Proteinvetenskap

    Author : Amina Bensabra; [2022]
    Keywords : cyanobacteria; metabolic engineering; cell-free metabolic engineering; enzymes; sustainability; cyanobakterier; metabolisk genteknik; syntetisk biologi; enzymer; hållbar bioproduktion;

    Abstract : Cyanobakterier är intressanta mikroorganismer för produktion av biobränslen från solljus, vatten och atmosfärisk koldioxid och anses därför vara potentiella mikrobiella cellfabriker. Men på grund av långsam tillväxt och låg produktion är genteknologi processen intensiv och tidskrävande för cyanobakterier. READ MORE

  3. 3. Characterization of bovine milk from indigenous species from Sri Lanka

    University essay from SLU/Department of Molecular Sciences

    Author : Jonathan Skager; [2022]
    Keywords : Milk; total proteolysis; protein profile; capillary electrophoresis; fluorescence; indigenous cattle; Jersey cattle; Friesian cattle; Sri Lanka;

    Abstract : Sri Lanka is a country in south Asia that from the beginning of the 21st century, until 2016 almost doubled their quantity in milk import, this to meet their national market demand for dairy products. The country is divided into different agroecological zones, which are the up-country, mid-country, and the lowlands. READ MORE

  4. 4. Comprehensive Study on Aptamers and Aptamer-based Assays

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Axel Truedson; Márta Sundström; Christoffer Eriksson; Andreas Bergfeldt; Matilda Jägare Lindvall; Caroline Normann; [2022]
    Keywords : Aptamer; Biotechnology; Detection method; Biosensor; Molecular recognition; Antibodies; Aptamerer; Bioteknik; Detektionsmetod; Biosensor; Molekylär igenkänning; Antikroppar;

    Abstract : Antibodies are the gold standard molecular recognition elements and a cornerstone of molecular biology. They are used in immunoassays to precisely measure a specific analyte, but certain targets are especially challenging. Difficult targets include small molecules and molecules that do not induce an immune response. READ MORE

  5. 5. X-Ray Fluorescence of Metal Halide Perovskites

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Samuel Narciso Silva; [2022]
    Keywords : Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

    Abstract : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. READ MORE
