The practice of introducing an additional round (or rounds) to the bidding to show extra information. Example: On a 1NT – 3NT auction, responder has gone quickly to the final contract. When instead the auction goes 1NT – 2 ♦ ; 2 ♥ – 3NT, responder has dawdled with the Jacoby Transfer to announce their 5-card heart suit before going to ...
Due to the strongly alkaline reaction conditions, aldehydes that have alpha hydrogen atom(s) instead undergo deprotonation there, leading to enolates and possible aldol reactions. Under ideal conditions the reaction produces 50% of both the alcohol and the carboxylic acid (it takes two aldehydes to produce one acid and one alcohol). [5]

Empirical (Na–Cs, Mg–Ra) and predicted (Fr–Uhp, Ubn–Uhh) atomic radius of the alkali and alkaline earth metals from the third to the ninth period, measured in angstroms [36]: 1730 [147] Although francium is the heaviest alkali metal that has been discovered, there has been some theoretical work predicting the physical and chemical ...
The simplest way of measuring the contact angle of a sessile drop is with a contact angle goniometer, which allows the user to measure the contact angle visually. A droplet is deposited by a syringe which is positioned above the sample surface, and a high resolution camera captures the image from the profile or side view.
The Scott Russell linkage (1803) translates linear motion through a right angle, but is not a straight line mechanism in itself. The Grasshopper beam/Evans linkage , an approximate straight line linkage, and the Bricard linkage, an exact straight line linkage, share similarities with the Scott Russell linkage and the Trammel of Archimedes .
