  2. Polybutylene terephthalate - Wikipedia

    en.wikipedia.org/wiki/Polybutylene_terephthalate

    Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. [2] It is a thermoplastic (semi-)crystalline polymer , and a type of polyester .

  3. Provider Backbone Bridge Traffic Engineering - Wikipedia

    en.wikipedia.org/wiki/Provider_Backbone_Bridge...

    Provider Backbone Bridge Traffic Engineering was originally developed in 2006 as a Nortel specific protocol named Provider Backbone Transport (PBT). The company championed the technology and brought it to the IEEE 802.1 committee where it was renamed to PBB-TE and a working group, P802.1Qay, was chartered on May 7, 2007.

  4. Persistent, bioaccumulative and toxic substances - Wikipedia

    en.wikipedia.org/wiki/Persistent,_bio...

    The PBT Strategy led to the implementation of PBT criteria in several regulational policies. Two main policies that were changed by the PBT strategy were the Toxics Release Inventory (TRI), which required more rigid chemical reporting, and the New Chemical Program (NCP) under the Toxics Substances Control Act (TSCA), which required screening ...

  5. Phosphate-buffered saline - Wikipedia

    en.wikipedia.org/wiki/Phosphate-buffered_saline

    There are many different ways to prepare PBS solutions, common ones are Dulbecco's phosphate-buffered saline (DPBS) [2] and the Cold Spring Harbor protocol. [3] Some formulations of DPBS do not contain potassium and magnesium, while other ones contain calcium and/or magnesium (depending on whether or not the buffer is used on live or fixed tissue: the latter does not require CaCl 2 or MgCl 2).

  6. IEEE 802.1aq - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.1aq

    IEEE 802.1aq is an amendment to the IEEE 802.1Q networking standard which adds support for Shortest Path Bridging (SPB). This technology is intended to simplify the creation and configuration of Ethernet networks while enabling multipath routing .

  7. Polybutylene - Wikipedia

    en.wikipedia.org/wiki/Polybutylene

    PB-1 is a high molecular weight, linear, isotactic, and semi-crystalline polymer. PB-1 combines typical characteristics of conventional polyolefins with certain properties of technical polymers.

  8. Surfactant protein B - Wikipedia

    en.wikipedia.org/wiki/Surfactant_protein_B

    Surfactant protein B is an essential lipid-associated protein found in pulmonary surfactant.Without it, the lung would not be able to inflate after a deep breath out. [5] It rearranges lipid molecules in the fluid lining the lung so that tiny air sacs in the lung, called alveoli, can more easily inflate.

  9. Xenoy - Wikipedia

    en.wikipedia.org/wiki/Xenoy

    It is typically polyester (polybutylene terephthalate, PBT, or polyethylene terephthalate, PET) and polycarbonate (PC): it is often labeled PBT+PC or PET+PC. [2] Xenoy resins can be created with recycled post-consumer PBT plastic, consuming less energy and yielding less carbon dioxide (CO 2) in their manufacturing than traditional resins.
