    en.wikipedia.org/wiki/Physically_based_rendering

    Physically based rendering (PBR) is a computer graphics approach that seeks to render images in a way that models the lights and surfaces with optics in the real world. It is often referred to as "Physically Based Lighting" or "Physically Based Shading". Many PBR pipelines aim to achieve photorealism.

  4. Phosphorus tribromide - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_tribromide

    PBr 3 is prepared by treating red phosphorus with bromine. An excess of phosphorus is used in order to prevent formation of PBr 5: [1] [2] P 4 + 6 Br 2 → 4 PBr 3. Because the reaction is highly exothermic, it is often conducted in the presence of a diluent such as PBr 3. Phosphorus tribromide is also generated in situ from red phosphorus and ...

    It is highly corrosive. It strongly irritates skin and eyes. [1] It decomposes above 100 °C to give phosphorus tribromide and bromine: [3] PBr 5PBr 3 + Br 2. Reversing this equilibrium to generate PBr 5 by addition of Br 2 to PBr 3 is difficult in practice because the product is susceptible to further addition to yield phosphorus ...

    en.wikipedia.org/wiki/Pabst_Blue_Ribbon

    Pabst Blue Ribbon, commonly abbreviated PBR, is an American lager beer sold by Pabst Brewing Company, established in Milwaukee, Wisconsin, in 1844 and currently based in San Antonio, Texas. Originally called Best Select , and then Pabst Select , the current name comes from the blue ribbons tied around the bottle's neck between 1882 and 1916.

  7. Performance-based regulation - Wikipedia

    en.wikipedia.org/wiki/Performance-based_regulation

    Performance-based regulation (PBR) is an approach to utility regulation designed to strengthen utility performance incentives. Thus defined, the term PBR is synonymous with incentive regulation. The two most common forms of PBR are award-penalty mechanisms (“APMs”) and multiyear rate plans (“MRPs”).

  8. pBR322 - Wikipedia

    en.wikipedia.org/wiki/PBR322

    pBR322 is 4361 base pairs in length [1] and has two antibiotic resistance genes – the gene bla encoding the ampicillin resistance (Amp R) protein, and the gene tetA encoding the tetracycline resistance (Tet R) protein. It contains the origin of replication of pMB1, and the rop gene, which encodes a restrictor of plasmid copy number.

    The Pusey–Barrett–Rudolph (PBR) theorem [1] is a no-go theorem in quantum foundations due to Matthew Pusey, Jonathan Barrett, and Terry Rudolph (for whom the theorem is named) in 2012. It has particular significance for how one may interpret the nature of the quantum state .
