    en.wikipedia.org/wiki/Transcatheter_aortic_valve...

    Transcatheter aortic valve replacement (TAVR) is the implantation of the aortic valve of the heart through the blood vessels without actual removal of the native valve (as opposed to the aortic valve replacement by open heart surgery, surgical aortic valve replacement, AVR).

  3. Agricultural soil science - Wikipedia

    en.wikipedia.org/wiki/Agricultural_soil_science

    Agricultural soil science follows the holistic method. Soil is investigated in relation to and as integral part of terrestrial ecosystems but is also recognized as a manageable natural resource. Agricultural soil science studies the chemical, physical, biological, and mineralogical composition of soils as they relate to agriculture.

  4. Tissue engineering of heart valves - Wikipedia

    en.wikipedia.org/wiki/Tissue_engineering_of...

    One animal trial combined the transcatheter aortic valve replacement (TAVR) procedure with tissue engineered heart valves (TEHVs). A TAVR stent integrated with human cell-derived extracellular matrix was implanted and examined in sheep, in which the valve upheld structural integrity and cell infiltration, allowing the potential clinical ...

  5. Cropping system - Wikipedia

    en.wikipedia.org/wiki/Cropping_system

    By affecting the soil in different ways, crops in a rotation help to stabilise changes in the properties. Another consideration is that many agricultural pests are species-specific and so having a given species present in a field only some of the time helps to prevent populations of pests from growing. [6]

  6. Soil management - Wikipedia

    en.wikipedia.org/wiki/Soil_management

  8. Regenerative agriculture - Wikipedia

    en.wikipedia.org/wiki/Regenerative_agriculture

    Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
