  2. Keloid - Wikipedia

    en.wikipedia.org/wiki/Keloid

    Keloids were described by Egyptian surgeons around 1700 BCE, recorded in the Smith papyrus, regarding surgical techniques. [citation needed] Baron Jean-Louis Alibert (1768–1837) identified the keloid as an entity in 1806. [citation needed] He called them cancroïde, later changing the name to chéloïde to avoid

  3. List of particles - Wikipedia

    en.wikipedia.org/wiki/List_of_particles

    Elementary particles are particles with no measurable internal structure; that is, it is unknown whether they are composed of other particles. [1] They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. Elementary particles are classified according to their spin.

  4. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Hexatic state, a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles. Ferroics; Ferroelastic state, a phenomenon in which a material may exhibit a spontaneous strain. Photon molecule: Photons which are connected with each other, attracted by apparent mass while mediating energy transfer.

  5. Hypertrophic scar - Wikipedia

    en.wikipedia.org/wiki/Hypertrophic_scar

    A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.

  6. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    Various types of colloids are recognised: inorganic colloids (e.g. clay particles, silicates, iron oxy-hydroxides), organic colloids (humic and fulvic substances). When heavy metals or radionuclides form their own pure colloids, the term " eigencolloid " is used to designate pure phases, i.e., pure Tc(OH) 4 , U(OH) 4 , or Am(OH) 3 .

  7. List of Egyptian hieroglyphs - Wikipedia

    en.wikipedia.org/wiki/List_of_Egyptian_hieroglyphs

    The total number of distinct Egyptian hieroglyphs increased over time from several hundred in the Middle Kingdom to several thousand during the Ptolemaic Kingdom.. In 1928/1929 Alan Gardiner published an overview of hieroglyphs, Gardiner's sign list, the basic modern standard.

  8. List of skin conditions - Wikipedia

    en.wikipedia.org/wiki/List_of_skin_conditions

    The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3] Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. [4]

  9. Kerogen - Wikipedia

    en.wikipedia.org/wiki/Kerogen

    The first-order Raman spectra of kerogen comprises two principal peaks; [15] a so-called G band ("graphitic") attributed to in-plane vibrational modes of well-ordered sp 2 carbon and a so-called D band ("disordered") from symmetric vibrational modes of sp 2 carbon associated with lattice defects and discontinuities.
