  1. 1. Informed System Protection

    Författare :Per Mellstrand; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Critical Infrastructures; Software Protection; In-depth Defense; Run-time Defense;

    Sammanfattning : Critical Infrastructure Protection (CIP) and Critical Information Infrastructure Protection (CIIP) are high-priority research areas in several international R&D efforts. There are different types of critical infrastructures, from physical such as the electrical power grid to virtual such as the Internet and other communication networks. LÄS MER

  3. 2. Protecting Software Execution by Dynamic Environment Hardening

    Författare :Per Mellstrand; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Software has an important role in many systems, in particular in critical systems where the correct function of the larger system is of utmost importance. Software malfunction, or software exploits, that allow other system components or an adversary to control the execution of software, can cause significant damage to the system, and hence to what is controlled by the system.

    Författare :Senia Johansson; Tore Mellstrand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; cytotoxic; neutrophil; polypeptides; Phoradendron tomentosum; Digitalis purpurea; plant; mistletoe; MS MS; Edman degradation; breast cancer; macrocyclic peptides; multidrug resistance protein; primary structures; phoratoxin; isolation; digitoxin; cardiac lycoside; structure-activity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; farmakognosi;

    Sammanfattning : This thesis examines the isolation and characterisation (biological and chemical) of polypeptides from plants. A fractionation protocol was developed and applied on 100 plant materials with the aim of isolating highly purified polypeptide fractions from small amounts of plant materials. LÄS MER
