  2. Polyhydroxyalkanoates - Wikipedia

    en.wikipedia.org/wiki/Polyhydroxyalkanoates

    For lack of nitrogen and phosphorus they produce a kilogram of PHA per three kilograms of sugar. The simplest and most commonly occurring form of PHA is the fermentative production of poly-beta-hydroxybutyrate [poly(3-hydroxybutyrate), P(3HB)], which consists of 1000 to 30000 hydroxy fatty acid monomers.

  3. Polyhydroxybutyrate - Wikipedia

    en.wikipedia.org/wiki/Polyhydroxybutyrate

    The poly-3-hydroxybutyrate (P3HB) form of PHB is probably the most common type of polyhydroxyalkanoate, but other polymers of this class are produced by a variety of organisms: these include poly-4-hydroxybutyrate (P4HB), polyhydroxyvalerate (PHV), polyhydroxyhexanoate (PHH), polyhydroxyoctanoate (PHO) and their copolymers.

  4. Process hazard analysis - Wikipedia

    en.wikipedia.org/wiki/Process_Hazard_Analysis

    A simple element of risk quantification is often introduced in the form of a risk matrix, as in preliminary hazard analysis (PreHA). The selection of the methodology to be used depends on a number of factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the ...

    en.wikipedia.org/wiki/Phytohaemagglutinin

    In medicine these proteins are useful and are used as a mitogen to trigger T-lymphocyte cell division and to activate latent HIV-1 from human peripheral lymphocytes.In neuroscience, anterograde tracing is a research method that uses the protein product phytohaemagglutinin PHA-L as a molecular tracer that can be taken up by the cell and transported across the synapse into the next cell thereby ...

  7. Cyber PHA - Wikipedia

    en.wikipedia.org/wiki/Cyber_PHA

    A cyber PHA or cyber HAZOP is a safety-oriented methodology to conduct a cybersecurity risk assessment for an industrial control system (ICS) or safety instrumented system (SIS). It is a systematic, consequence-driven approach that is based upon industry standards such as ISA 62443-3-2 , ISA TR84.00.09, ISO/IEC 27005 :2018, ISO 31000 :2009 and ...

  8. 3-Hydroxypropionic acid - Wikipedia

    en.wikipedia.org/wiki/3-hydroxypropionic_acid

    3-Hydroxypropionic acid is of interest as a bio-derived precursor to acrylic acid. [5]The polyester poly(3-hydroxypropionic acid) is a biodegradable polymer. [7] The method combines the high-molecular weight and control aspects of ring-opening polymerization with the commercial availability of the beta hydroxy acid, 3-hydroxypropionic acid which is abbreviated as 3-HP.

  9. PHBV - Wikipedia

    en.wikipedia.org/wiki/PHBV

    Poly(3-hydroxybutyrate-co-3-hydroxyvalerate), commonly known as PHBV, is a polyhydroxyalkanoate-type polymer.It is biodegradable, nontoxic, biocompatible plastic produced naturally by bacteria and a good alternative for many non-biodegradable synthetic polymers.
