    An evaporative diffuser is a device that uses a pad, filter, or reeds to diffuse the essential oils. [2] One of the disadvantages of this tool is that the light elements of the essential oils will be circulated around the ceiling first and will only come down at the end of the process.

    Essential oils can be used in aromatherapy by using essential oil diffusers. [17] Aromatherapy is a form of alternative medicine in which healing effects are ascribed to the aromatic compounds in essential oils and other plant extracts.

  5. Diffusion-weighted magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Diffusion-weighted...

    At the end, images are "weighted" by the diffusion process: In those diffusion-weighted images (DWI) the signal is more attenuated the faster the diffusion and the larger the b factor is. However, those diffusion-weighted images are still also sensitive to T1 and T2 relaxivity contrast, which can sometimes be confusing.

  6. Blend modes - Wikipedia

    en.wikipedia.org/wiki/Blend_modes

    A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes [1] or mixing modes [2]) in digital image editing and computer graphics are used to determine how two layers are blended with each other.

  7. 3D printing filament - Wikipedia

    en.wikipedia.org/wiki/3D_printing_filament

    The plastic nurdles are always white or clear. Pigments or other additives are added to the material before it is melted to create coloured filament or filament with special properties, e.g. increased strength or magnetic properties. Before the filament is extruded the nurdles are heated to 80 °C to dry it and reduce water content.

  8. Room air distribution - Wikipedia

    en.wikipedia.org/wiki/Room_air_distribution

    Displacement ventilation systems supply air directly to the occupied zone.The air is supplied at low velocities to cause minimal induction and mixing. This system is used for ventilation and cooling of large high spaces, such as auditorium and atria, where energy may be saved if only the occupied zone is treated rather than trying to control the conditions in the entire space.

  9. Diffuser (automotive) - Wikipedia

    Top: Lateral view; the red circles mark the front air dam/splitter and rear diffuser. Bottom: Rear. A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere.
