"Reynolds Rocket" pen was introduced at Gimbel’s department store in New York City, selling $100,000 worth of pens on the first day. [2] Demand in 1945 was running 30,000 pens per day, making it America's #1 ballpoint pen. [3] However, within three years the price of the pen went from $12.50 to 50¢.
In 1955, the state owned Ceylon Government Railway manufactured Sri Lanka's "first" diesel-electric locomotive using old spares from the withdrawn and scrapped Class S1 DMU power sets. This locomotive was named "Jayanthi" and classified as the Class M3 No. 589. The locomotive was put to service on 5 September 1956.
Genentech developed the technique used to produce the first such insulin, Humulin, but did not commercially market the product themselves. Eli Lilly marketed Humulin in 1982. [28] Humulin was the first medication produced using modern genetic engineering techniques in which actual human DNA is inserted into a host cell (E. coli in this case ...
Humulin R Regular U-500 (Concentrated) insulin human injection, USP (rDNA Origin) is a stronger concentration (500 units/mL) of Humulin R. Humulin 70/30 (70% human insulin isophane suspension, 30% human insulin injection [rDNA origin]) is a mixture insulin. It is an intermediate-acting insulin combined with the onset of action of Humulin
Humulene, also known as α-humulene or α-caryophyllene, is a naturally occurring monocyclic sesquiterpene (C 15 H 24), containing an 11-membered ring and consisting of 3 isoprene units containing three nonconjugated C=C double bonds, two of them being triply substituted and one being doubly substituted.
In the 1990s, Sri Lanka Railways converted the 2 ft 6 in (762 mm) narrow gauge Kelani Valley line into 5 ft 6 in (1,676 mm) broad gauge. This was the last narrow gauge line left in Sri Lanka, and its conversion to broad gauge put the fleet of narrow gauge locomotives out of use. All operational locomotives in the country today are broad gauge.
A number of different units of measurement were used in Sri Lanka to measure quantities like length, mass and capacity from very ancient times. [1] Under the British Empire, imperial units became the official units of measurement [2] and remained so until Sri Lanka adopted the metric system in the 1970s. [3] [4]
Gel pens can be used for many types of writing and illustration. The general design of a gel pen is similar to that of a regular ink-based pen, with a barrel containing the writing mechanism and a cap, and a reservoir filled with ink. At the end of the ink tube is an ink "follower", made of more viscous gelled material which is usually ...
