A planned unit development (PUD) is a type of flexible, non-Euclidean zoning device that redefines the land uses allowed within a stated land area. PUDs consist of unitary site plans that promote the creation of open spaces, mixed-use housing and land uses, environmental preservation and sustainability, and development flexibility. [1]
Rhodoblastus acidophilus, formerly known as Rhodopseudomonas acidophila, is a gram-negative purple non-sulfur bacteria. [1] [2] The cells are rod-shaped or ovoid, 1.0 to 1.3 μm wide and 2 to 5 μm long.
This allows for blue–white screening when using host strains such as E. coli JM109, which produces only the C-terminal portion of lacZ, also known as the β-polypeptide. [3] If pUC19 is inserted into E. coli JM109 and grown on agar media supplemented with IPTG and X-gal , then colonies will appear blue, as the plasmid encodes for the α ...
The strain is a high quality bud originating in northeast Thailand, where it was grown by hill tribes since antiquity. The name comes from a traditional Thai method of preparing cannabis to be smoked, which involved wrapping cannabis bud around a stick. [ 90 ]
Ralph Wiley accidentally discovered polyvinylidene chloride polymer in 1933. [2] At the time he was a college student who worked part-time at Dow Chemical lab as a dishwasher. [3]
Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone. [1]
The strain became popular during the '80s when various strains of cannabis landed in the area of Idukki in Kerala. [4] [5] The climate of the Western Ghats was ideal and the strain soon started spreading. Later, the strain received the name Idukki Gold. Known as Neelachadayan (blue locks) or Neelam in the native tongue.
Multiple strains of R. sulfidophilum have also been shown to be capable of photoferrotrophy, a process that fixes inorganic carbon to organic material using light and Fe(II) as the electron donor. [17] [18] Rhodovulum sulfidophilum DSM 2351 is found to produce and excrete high levels of nucleic acids, which causes cell aggregates to form. [19]
