Gibberellic acid is a very potent hormone whose natural occurrence in plants controls their development. Since GA regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect. [3] It is usually used in concentrations between 0.01 and 10 mg/L. [citation needed]
Gibberellic acid, which was the first gibberellin to be structurally characterized, is GA 3. [6] As of 2020, [5] there are 136 GAs identified from plants, fungi, and bacteria. [1] [6] [5] Gibberellins are tetracyclic diterpene acids. There are two classes, with either 19 or 20 carbons.
Conductive level sensors are ideal for the point level detection of a wide range of conductive liquids such as water, and is especially well suited for highly corrosive liquids such as caustic soda, hydrochloric acid, nitric acid, ferric chloride, and similar liquids. For those conductive liquids that are corrosive, the sensor's electrodes need ...
A bath of ice and water will maintain a temperature 0 °C, since the melting point of water is 0 °C. However, adding a salt such as sodium chloride will lower the temperature through the property of freezing-point depression. Although the exact temperature can be hard to control, the weight ratio of salt to ice influences the temperature:
1-Triacontanol (n-triacontanol) is a fatty alcohol of the general formula C 30 H 62 O, also known as melissyl alcohol or myricyl alcohol.It is found in plant cuticle waxes and in beeswax.
Commercial swimming pools also require chemical dosing in order to control pH balance, chlorine level, and other such water quality criteria. Modern swimming pool plant will have bulk storage of chemicals held in separate dosing tanks , and will have automated controls and dosing pumps to top up the various chemicals as required to control the ...
Temperature measuring and controlling module for microcontroller experiment. Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature.
Allows water to be stored at a higher temperature; Group Control. These provide a uniform distribution temperature for all hot water outlets in a household. Designed for multi-point applications; High flow rates (from 14 to 51 US gallons per minute (53 to 193 L/min) at 45 pounds per square inch (3.1 bar)) Temperature stability; Point-of-Use
