  1. A country's gross domestic product (GDP) at purchasing power parity (PPP) per capita is the PPP value of all final goods and services produced within an economy in a given year, divided by the average (or mid-year) population for the same year. This is similar to nominal GDP per capita but adjusted for the cost of living in each country.

  2. The first set of data on the left columns of the table includes estimates for the year 2023 made for each economy of the 196 economies (189 U.N. member states and 7 areas of Aruba, Hong Kong, Kosovo, Macau, Palestine, Puerto Rico, and Taiwan) covered by the International Monetary Fund (IMF)'s International Financial Statistics (IFS) database.

    Medical uses

    1. Pharmaceutical-grade PEG is used as an excipientin many pharmaceutical products, in oral, topical, and parenteral dosage forms. 2. PEG is the basis of a number of laxatives (as MiraLax, RestoraLAX, etc.). Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy or for children with constipation. Macrogol (with brand names such as Laxido, Movicol and Miralax) is the generic name for polyethylene glycol used as a laxat...

    Chemical uses

    1. Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluidin electronic testers. 2. PEG is frequently used to preserve waterlogged wood and other organic artifacts that have been salvaged from underwater archaeological contexts, as was the case with the warship Vasa in Stockholm, and similar cases. It replaces water in wooden objects, making the wood dimensionally stable and preventing warping or shrinking of the wood when...

    Biological uses

    1. An example study was done using PEG-diacrylate hydrogels to recreate vascular environments with the encapsulation of endothelial cells and macrophages. This model furthered vascular disease modeling and isolated macrophage phenotype's effect on blood vessels. 2. PEG is commonly used as a crowding agent in in vitro assays to mimic highly crowded cellular conditions. Although polyethylene glycol is considered biologically inert, it can form non-covalent complexes with monovalent cations such...

    PEG is considered biologically inert and safe by the U.S. FDA. However, a growing body of evidence shows the existence of a detectable level of anti-PEG antibodies in approximately 72% of the population, never treated with PEGylated drugs, based on plasma samples from 1990 to 1999.[further explanation needed] Due to its ubiquity in a multitude of p...

    PEG, PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry. Because different applications require different polymer chain lengths, PEG has tended to refer to oligomers and p...

    The production of polyethylene glycol was first reported in 1859. Both A. V. Lourenço and Charles Adolphe Wurtz independently isolated products that were polyethylene glycols. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. The reaction is catalyzed by acidic or basic c...

    PEO's have "very low singledose oral toxicity", on the order of tens of grams per kg body weight (oral). Because of its low toxicity, PEO is used in a variety of edible products.The polymer is used as a lubricating coating for various surfaces in aqueous and non-aqueous environments. The precursor to PEGs is ethylene oxide, which is hazardous. Ethy...

  3. Historical data can be found here. Table. The table initially ranks each country or territory by its IMF estimate, and can be reranked by any of the sources. Notes:

  4. according to International Monetary Fund estimates [n 1] [1] Countries by nominal GDP in 2019 [n 2] > $20 trillion. $10–20 trillion. $5–10 trillion. $1–5 trillion. $750 billion – $1 trillion. $500–750 billion. $250–500 billion.

  5. List. The Human Development Report includes data for all 193 member states of the United Nations, [16] as well as Hong Kong SAR and the State of Palestine. However, the Human Development Index is not calculated for two UN member states: DPR Korea (North Korea) and Monaco, only some components of the index are calculated for these two countries.

  6. Ethylenediaminetetraacetic acid ( EDTA ), also called EDTA acid after its own abbreviation, is an aminopolycarboxylic acid with the formula [CH 2 N (CH 2 CO 2 H) 2] 2. This white, water-insoluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+ ), forming water-soluble complexes even at neutral pH.
