Gram

The gram (alternative British English spelling: gramme;SI unit symbol: g) (Greek/Latin root grámma) is a metric system unit of mass. Gram can be abbreviated as gm or g.

Originally defined as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice" (later 4 °C), a gram is now defined as one one-thousandth of the SI base unit, the kilogram, or 1×10−3 kg, which itself is defined as being equal to the mass of a physical prototype preserved by the International Bureau of Weights and Measures.

Official SI symbol

The only unit symbol for gram that is recognised by the International System of Units (SI) is "g" following the numeric value with a space, as in "640 g". The SI does not support the use of abbreviations such as "gr" (which is the symbol for grains), "gm" or "Gm" (the SI symbol for gigametre).

History

The word gramme was adopted by the French National Convention in its 1795 decree revising the metric system as replacing the gravet introduced in 1793. Its definition remained that of the weight (poids) of a cubic centimetre of water. French gramme was taken from the Late Latin term gramma. This word, ultimately from Greek γράμμα "letter" had adopted a specialised meaning in Late Antiquity of "one twenty-fourth part of an ounce" (two oboli), corresponding to about 1.14 (modern) grams. This use of the term is found in the carmen de ponderibus et mensuris ("poem about weights and measures") composed around 400 AD. There is also evidence that the Greek γράμμα was used in the same sense at around the same time, in the 4th century, and survived in this sense into Medieval Greek, while the Latin term did not remain current in Medieval Latin and was recovered in Renaissance scholarship.

Gram-negative bacteria

Gram-negative bacteria are a group of bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation, making positive identification possible. The thin peptidoglycan layer of their cell wall is sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. After staining with crystal violet, an alcohol wash is applied which decolorizes the bacteria showing that their peptidoglycan layer is too thin to retain the stain and enabling identification. A counterstain (safranin or fuchsine) is then added which recolorizes the bacteria red or pink.

Gram-positive bacteria have a thicker peptidoglycan layer in their cell wall outside the cell membrane, which retains the crystal violet stain during the alcohol wash, so long as it is timed correctly. The counter stain may also be absorbed by gram-positive bacteria but the darker crystal violet stain predominates.

Você Pode Ir Na Janela

by: GRAM

Se não vai
Não desvie a minha estrela
Não desloque a linha reta
Você só me fez mudar
Mas depois mudou de mim
Você quer me biografar
Mas não quer saber do fim
Mas se vai
Você pode ir na janela
A se amorenar no Sol
Que não quer anoitecer
E ao chegar no meu jardim
Mostro as flores que falei
Vai sem duvidar
Mas se ainda faz sentido, vem
Até se for bem no final
Será mais lindo
Como a canção que um dia fiz
Pra te brindar
Você pode ir na janela
A se amorenar no Sol
Que não quer anoitecer
E ao chegar no meu jardim
Mostro as flores que falei
Você só me fez mudar
Mas depois mudou de mim
