An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
Anticholinergic overdose, both antinicotinic and antimuscarinic, can exert toxic effects on both central and peripheral systems. The following symptoms could be presented: [21] [22] Mydriasis. Mild symptoms include tachycardia, flushed face, mydriasis and blurred vision, fever, dry mouth and skin, and urinary retention.
Scopolamine, an anticholinergic drug, was used to block cholinergic activity in young adults and induce memory impairments similar to those present in the elderly. The memory impairments were reversed when treated with physostigmine , a cholinergic agonist.

The scale was one among several systems intended to provide information for researchers developing tools to determine the safety fitness of a vehicle. [7] Considering an unrelated possible non-commercial application, in 2015 the Federal Highway Administration wrote: "Recording and collecting data from on-board load cells can provide a metric ...
The superficial Rockwell scales use lower loads and shallower impressions on brittle and very thin materials. The 45N scale employs a 45-kgf load on a diamond cone-shaped Brale indenter, and can be used on dense ceramics. The 15T scale employs a 15-kgf load on a 1 ⁄ 16-inch-diameter (1.588 mm) hardened steel ball, and can be used on sheet metal.
A beltweigher or belt weigher, more commonly known as a belt scale, is a piece of industrial control equipment used to measure the mass and flow rate of bulk material traveling over a conveyor belt. [1] Invented by Herbert Merrick in the early 1900's, belt weighers are commonly used in plants and heavy industries, such as mining. [2]
Trihexyphenidyl is an anticholinergic. [21] It is specifically an antimuscarinic and acts as a non-selective antagonist of all five muscarinic acetylcholine receptors. [21] However, its antagonistic activity is much stronger at the muscarinic acetylcholine M 1 and M 4 receptors, and it can be described as selective for these receptors. [21] [22]
