The 1985 Austrian diethylene glycol wine scandal (German: Glykolwein-Skandal) was an incident in which several Austrian wineries illegally adulterated their wines using the toxic substance diethylene glycol (a minor ingredient in some brands of antifreeze) to make the wines taste sweeter and more full-bodied in the style of late harvest wines.

Antifreeze was developed to overcome the shortcomings of water as a heat transfer fluid. On the other hand, if the engine coolant gets too hot, it might boil while inside the engine, causing voids (pockets of steam), leading to localized hot spots and the catastrophic failure of the engine. If plain water were to be used as an engine coolant in ...
Waterless coolant is most prominently used in the cooling systems for motorsports, classic car, ATVs, UTVs, snowmobiles and older cars. [4] Older cars often have non-pressurized cooling systems, and the water-based coolant can boil and overflow. Traditionally, this issue has been solved by topping off the radiator with water. This dilutes the ...
This is accomplished through the use of a coolant such as liquid nitrogen or a freezing mixture of dry ice in acetone or a similar solvent with a low melting point. Liquid nitrogen is only used when dry ice or other cryogenic approaches will not condense the desired gasses since liquid nitrogen will also condense oxygen.
According to the structure and function study on the antifreeze protein from Pseudopleuronectes americanus, [55] the antifreeze mechanism of the type-I AFP molecule was shown to be due to the binding to an ice nucleation structure in a zipper-like fashion through hydrogen bonding of the hydroxyl groups of its four Thr residues to the oxygens ...
If present, the fuse plug is designed to wash out in case of a large flood greater than the discharge capacity of the spillway gates. Although many months may be needed for construction crews to restore the fuse plug and channel after such an operation, the total damage and cost to repair is less than if the main water-retaining structures had ...
The mixture of FSII must be between 0.10% and 0.15% by volume for the additive to work correctly, and the FSII must be distributed evenly throughout the fuel. Simply adding FSII after the fuel has been pumped is therefore not sufficient. As aircraft climbs after takeoff, the temperature drops, and any dissolved water will separate out from the ...
Sanitary sewer overflow (SSO) is a condition in which untreated sewage is discharged from a sanitary sewer into the environment prior to reaching sewage treatment facilities. When caused by rainfall it is also known as wet weather overflow .
