Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g. Sweden, Denmark, Norway, Finland, Germany, and Switzerland use mass-mass concentrations in their laws, [ 6 ] but this distinction is often skipped over in public materials, [ 12 ...
Spain: 0.05% BAC (0.25 mg/L BrAC) [124] and 0.03% BAC (0.15 mg/L BrAC) for drivers with less than two years' experience and drivers of freight vehicles over 3.5 tonnes, and of passenger vehicles with more than nine seats. 0 for drivers under 18. [82] Surpassing the limit is a serious offense, fined with €500. [125]
[19] [20] A 1995 Würzburg University study of German data similarly found that the risk of collisions appeared to be lower for drivers with a BAC of 0.04% or less than for drivers with a BAC of 0%. [19] Studies of alcohol impairment on tests of driving ability have found that impairment starts as soon as alcohol is detectable.
However, the effect only affects alloys with more than 0.8% Mg2Si (excluding Mg or Si surpluses) and alloys with more than 0.6% Mg2Si if Mg or Si surpluses are present. To prevent these negative effects, AlMgSi can be annealed after quenching at 80 °C for 5–30 minutes, which stabilizes the material condition and temporarily does not change.
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
Nutritional iodine is better supplied in the form of the less toxic iodide (see SSKI) or iodate salts, which the body can easily convert to thyroid hormone. Nevertheless, the iodide in tincture of iodine used as a water disinfectant does supply more than adequate nutritional iodine, perhaps 30 or more times the recommended daily allowance per ...
gives a probability that a statistic is greater than Z. This equates to the area of the distribution above Z. Example: Find Prob(Z ≥ 0.69). Since this is the portion of the area above Z, the proportion that is greater than Z is found by subtracting Z from 1. That is Prob(Z ≥ 0.69) = 1 − Prob(Z ≤ 0.69) or {{{1}}}.
If the ratio is less than 1/1, clusters containing Cu and Mg are eliminated. At a ratio above 1.5/1, which is the case with most engineering alloys, the forms preferentially phase. These kinds of alloys have significantly higher hardness and strength.
