  2. 1. Plant-Derived Chemicals as Tick Repellents

    Author : Samira Sadek Garboui; Thomas Jaenson; Katinka Pålsson; Raimondas Mozuraitis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ixodes ricinus; plants; essential oils; tick repellent; Sweden; Biology; Biologi;

    Abstract : Ixodes ricinus is the main vector of Lyme borreliosis and Tick-borne encephalitis in Europe. Repellents provide a practical means of protection against tick bites and can therefore reduce transmission of tick-borne diseases. READ MORE

  4. 2. Thin-film ultraviolet light-emitting diodes realized by electrochemical etching of AlGaN

    Author : Michael Alexander Bergmann; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thin-film flip-chip; light-emitting diodes; UVB; AlGaN; thermocompression bonding; substrate removal; ultraviolet light; electrochemical etching; heterogeneous integration; LEDs;

    Abstract : Ultraviolet (UV) light sources have a direct impact on everyone’s life. They are used to sterilize surfaces as well as for water purification. In addition, they are used in green houses to enhance health-promoting substances in plants, for phototherapy to treat skin diseases, for sensing and material curing. READ MORE

  5. 3. Studies towards late blight control in potato

    Author : Laith Moushib; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oomycetes; plant induced resistance; sustainable agriculture; plant defence activators; plant innate immunity; potato; late blight;

    Abstract : Abstract The oomycete Phytophthora infestans, which causes the devastating late blight disease of potato, is notorious for developing resistance to conventional control strategies (fungicide application and resistance breeding by introgression of R gene). To increase our tool box of disease management strategies available to combat P. READ MORE

  6. 4. Insect-plant interactions within cultivar mixtures : volatile plant communication as an underlying mechanism

    Author : Sokha Kheam; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Promoting genotypic diversity of crops via cultivar mixtures presents a promising strategy to sustainably control insect pests and diseases, and thereby enhance yield. However, the underlying mechanisms responsible for reduced pest performance in cultivar mixtures remain unexplored. READ MORE
