Butter may be measured by either weight (1 ⁄ 4 lb) or volume (3 tbsp) or a combination of weight and volume (1 ⁄ 4 lb plus 3 tbsp); it is sold by weight but in packages marked to facilitate common divisions by eye. (As a sub-packaged unit, a stick of butter, at 1 ⁄ 4 lb [113 g], is a de facto measure in the US.)
Many high schools use butchers' paper for posters of clubs, and upcoming events. It is a cheap but sturdy paper that is sold in large rolls. Butcher paper is usually white or reddish in colour, made from kraft pulp , and is generally considered to have a density of between 30 lb/3000 sq ft (49 g/m 2 ) and 50 lb/3000 sq ft (81 g/m 2 ).
Taking the standard (but no longer existent) 70kg medical adult, and using the lesser fatal dose of 20mg/kg gives the fatal oral dose to be 1400mg - about 0.6 pounds - of pure ricin. Even if each castor bean is 100% ricin (which seems improbable) then with a fatal dose range of 5-20 beans, each bean must weigh between 0.5 and 2 ounces.
In 2010, approximately 36.9 billion pounds (16,737,558 tonnes) of broilers were sold, for a retail value of $45 billion, based on retail weight sold multiplied by the retail composite price. In 2010, the US exported 6.8 billion pounds, valued at $3.1 billion, about 18% of production. [citation needed] In 2009, the US produced 8.6 billion birds.
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.
On Oct. 9, the U.S. Department of Agriculture’s Food Safety and Inspection Service announced a widespread recall of nearly 10 million pounds of ready-to-eat meat and poultry products produced by ...
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]
A paper bundle is a quantity of sheets of paper, currently standardized as 1,000 sheets. A bundle consists of two reams or 40 quires. As an old UK and US measure, it was previously equal to 960 sheets. [9] When referring to chipboard, there are two standards in the US. In general, a package of approximately 50 pounds of chipboard is called a ...
