A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 1 ⁄ 20 of a ream of 500 sheets. Quires of 25 sheets are often used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams.
Liquid packaging board is a multi-ply paperboard with high stiffness, strong wet sizing and a high barrier coating, e.g. plastic. Only virgin paper fibers are used. The barrier coating must hold the liquid and prevent migration of air and flavors through the paperboard.
It can serve as a biomarker of ricin poisoning. [3] [4] It was first isolated from the castor seeds by Tuson in 1864. [5] [6] Ricinine has insecticidal effects. [7] It sublimes between 170 and 180 °C at 20 mmHg. It does not form salts, and is precipitated in iodine or mercuric chloride solutions, but not in Mayer's reagent. [5]
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.
The water ton is used chiefly in Great Britain, in statistics dealing with petroleum products, and is defined as 224 imperial gallons (35.96 cu ft; 1.018 m 3), [22] the volume occupied by 1 long ton (2,240 lb; 1,016 kg) of water under the conditions that define the imperial gallon.
The tun (Old English: tunne, Latin: tunellus, Medieval Latin: tunna) is an English unit of liquid volume (not weight), used for measuring wine, [1] oil or honey. Typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used. [2]
A Canadian woman was sentenced to nearly 22 years in prison in Washington Thursday in the mailing of a threatening letter containing the poison ricin to then-President Donald Trump at the White House.
Conversely, the ton used in specifying tonnage and in freight calculations is often a volume measurement rather than a mass measurement. In US cooking, dry and liquid measures are the same: the cup, the tablespoon, the teaspoon. US dry measures are 16% larger than liquid measures.
