    Abstract : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. READ MORE

    Keywords : MEDICINE; MEDICIN;

    Abstract : Diet has for many years been known to play a key role in the development of chronic diseases. There are clear associations between consumption of vegetables, fruits and berries, and risk of cardiovascular diseases, the number one cause of death in the world. READ MORE

  5. 3. Enhanced Biological Phosphorus Removal -Processes, Competing Substances and Tools for Operation of Wastewater Treatment Plants

    Author : Eva Tykesson; Vattenförsörjnings- och avloppsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; chemical precipitation; glycogen accumulating organisms; polyphosphate accumulating organisms; wastewater treatment; biological phosphorus removal; kontroll av utsläpp;

    Abstract : The idea of phosphorus removal at wastewater treatment plants is to transfer dissolved phosphorus into a solid phase. Together with the rest of the produced sludge it is then removed from the water, resulting in a decreased concentration of phosphorus in the effluent and the prevention of the eutrophication in the recipient.

    Abstract : Colon cancer is common in both developed and developing countries, and is responsible for at least 600,000 deaths globally every year. It is therefore the second most common cause of cancer-related mortality. Extensive studies are being conducted worldwide to find more effective drugs that can be used in cancer treatment. READ MORE

  7. 5. Identification of bull semen microbiota and possible alternatives for antibiotics in semen extenders

    Author : Aleksandar Cojkic; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The use of 16S rRNA sequencing has revolutionised research on the microbiome. However, few studies using this method have been done on semen from healthy bulls. Such information is required to optimise addition of antibiotics to semen extenders to inhibit growth of bacteria. READ MORE
