  2. 1. Strategic raw material supply for the particleboard-producing industry in Europe : Problems and challenges

    Author : Johann Trischler; Johan Bergh; Rupert Wimmer; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass production; Lignocellulosic raw material; Non-wood plants; Particleboard; Pulp and paper; Recycling; Thermal energy recovery; Wood plants; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Particleboard was invented to increase the utilization of wood and it soon became an important core material for furniture production. Nowadays, other industries such as the pulp and papermaking industry and the thermal energy recovery industry claim the same type of raw material. READ MORE

  4. 2. Macrocyclic polypeptides from plants

    Author : Ulf Göransson; David Craik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; Farmakognosi;

    Abstract : The aim of this work was to explore the structural and functional diversity of polypeptides that are found in plants. Expanding knowledge of simililarities between plant use of these compound and animal use promises exceptional opportunities for finding, from plant research, new structures with biomedical and biotechnological potential.

  5. 3. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

    Author : Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

    Abstract : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. READ MORE

  6. 4. Plants as Sources of Natural and Effective Acaricides : Against Ixodes ricinus  (Acari: Ixodidae)

    Author : Fawzeia Elmhalli; Giulio Grandi; Richard Wall; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acaricidal; Ixodes ricinus; Libyan plants; essential oils; Plant-derived acaricides.; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Ticks and tick-borne diseases are major health hazards worldwide, with increasing numbers of cases of Lyme disease and tick-borne encephalitis reported yearly. Meanwhile, concerns about the environmental impact and safety of chemical acaricides are driving research into alternative control methods, such as plant-based acaricides. READ MORE

  7. 5. Desert Plants and Deserted Islands : Systematics and Ethnobotany in Caryophyllaceae
