    edit. Stable Z/N chart of La and Ba. Naturally occurring lanthanum (57 La) is composed of one stable (139 La) and one radioactive (138 La) isotope, with the stable isotope, 139 La, being the most abundant (99.91% natural abundance). There are 39 radioisotopes that have been characterized, with the most stable being 138 La, with a half-life of 1 ...

  5. Positron annihilation spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Positron_annihilation...

    Ps can pick up a molecular electron with an opposite spin to that of the positron, leading to a reduction of the o-Ps lifetime from 142 ns to 1-4 ns (depending on the size of the free volume in which it resides). [4] The size of the molecular free volume can be derived from the o-Ps lifetime via the semi-empirical Tao-Eldrup model. [5]

  6. Glycemic index - Wikipedia

    en.wikipedia.org/wiki/Glycemic_index

    The glycemic (glycaemic) index (GI; / ɡ l aɪ ˈ s iː m ɪ k / [1]) is a number from 0 to 100 assigned to a food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food. [2] The GI of a specific food depends primarily on the quantity and type of ...

  7. Total fertility rate - Wikipedia

    en.wikipedia.org/wiki/Total_fertility_rate

    A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...

  8. Glycemic load - Wikipedia

    en.wikipedia.org/wiki/Glycemic_load

    Glycemic load of a 100 g serving of food can be calculated as its carbohydrate content measured in grams (g), multiplied by the food's GI, and divided by 100. For example, watermelon has a GI of 72. A 100 g serving of watermelon has 5 g of available carbohydrates (it contains a lot of water), making the calculation (5 × 72)/100=3.6, so the GL ...

  9. Life table - Wikipedia

    en.wikipedia.org/wiki/Life_table

    Life table. In actuarial science and demography, a life table (also called a mortality table or actuarial table) is a table which shows, for each age, the probability that a person of that age will die before their next birthday ("probability of death "). In other words, it represents the survivorship of people from a certain population. [1]
