  1. 21. Some Approaches to Eco-Friendly Products from Natural Matrices

    Författare :Joel Ljunggren; Erik Hedenström; Olav Martin Kvalheim; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Since the onset of the industrial and chemical revolution, humans have caused immense damages to the surrounding flora and fauna. Effective methods for wood protection measures proved to be toxic; fossil fuels contribute to global warming and pesticides can be detected in the air, water, and soil. LÄS MER

  3. 22. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology

    Sammanfattning : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. LÄS MER

    Författare :Yufeng Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nasopharyngeal carcinoma (NPC) is a malignancy known for its unique geographic and ethnic distribution characterized by particularly high incidence in southern China, Southeast Asia, and North and East Africa, but being rare in the rest of the world. Its etiology has remained enigmatic and the accumulated evidence suggests that genetic predisposition, environmental factors, and infection with Epstein-Barr virus (EBV) are involved. LÄS MER
