Brown Mucus On First Day Of Period

Norme di scrittura nel S.I.

My colleague Mr. Gianluca Lazzaroni (Technical Study Lazzaroni - Brescia) sent us a note technical information, which I find it useful to be published in order to assist all those who engage in the preparation of valuations. Those are the rules of the International System of writing that, more often, are disregarded and ignored.
To standardize the spelling and avoid mistakes di interpretazione, il SI prevede alcune norme per la scrittura delle unità di misura e dei relativi simboli.

Scrittura delle unità
Per quanto riguarda le unità di misura, esse dovrebbero essere scritte per esteso, e non indicate con il simbolo, se inserite in un testo discorsivo; la scrittura estesa deve essere in carattere tondo minuscolo e si devono evitare segni grafici come accenti o segni diacritici. Ad esempio si deve scrivere ampere, e non ampère o Ampere.

Scrittura dei simboli
Quando si usano i simboli, questi devono essere indicati con l'iniziale minuscola, ad eccezione di quelli in cui l'unità di misura è eponima o deriva dal nome di una persona; For example, you write per kilogram kilograms and not pounds, while the symbol of the pressure, dedicated to Blaise Pascal, Pa is, while the unit is spelled out in tiny pascal. The second is whether non-sec, not gr g gram. The only exception is allowed per gallon where it is acceptable that both the L.
Instead of abbreviations, symbols of the SI should never be followed by a period (for the metro: I do not m.), they must also follow and not precede the numeric value (it says 20 cm, and 20 cm) with a space between numbers and symbols: 2.21 kg, 7.3 · 102 m². The units consist of (for example, the newton meters: N m) symbols of the individual units must be separated by a space or a half-height, [2] is not permissible to use other characters, such as the dash for example we can write N m or N • m, but not in Nm case of division between units of measure, you can use the fraction / (or the horizontal bar) or a negative exponent, eg J / kg or J kg-1 or J-1 · kg.
If necessary, groups of units can be put in brackets: J / mol K or J / mol K · · K-1 or J-1 or J · mol (· mol K) -1.
It is preferable not to use bold or italics for symbols, so as to distinguish them from mathematical and physical variables (eg, m for mass, l for length).

Writing figures
The SI uses spaces to separate whole numbers in groups of three. For example 1000000 or 342 142 (in contrast to the commas and the dots used in other systems: 1,000,000 or 1,000,000). In addition, the SI uses the comma as a separator between the whole numbers and decimals as those in 24.51. In 2003, the GFCM has granted the opportunity to use point in the texts in English.

Legal Provisions
The SI is used in every nation and, in some of them, its use is required. As in Italy, where the use of IT has been officially adopted by law under the Royal Decree No 23 August 1890 7088 and in Council Directive of 18 October 1971 71/1354/CEE amended July 27, 1976 (76/770/EEC), its use is required in the preparation of records and documents with legal value, so the non-compliance could lead to the aforementioned write invalidation of such acts.
