Tree spiking involves hammering a metal rod, nail or other material into a tree trunk, either inserting it at the base of the trunk where a logger might be expected to cut into the tree, or higher up where it would affect the sawmill later processing the wood. Contact with the spike often damages saw blades, which can result in injuries, or ...
Standard addition involves adding known amounts of analyte to an unknown sample, a process known as spiking. By increasing the number of spikes, the analyst can extrapolate for the analyte concentration in the unknown that has not been spiked. [2] There are multiple approaches to the standard addition. The following section summarize each approach.
Spiking is a form of forest industry sabotage, according to TDF. The practice seeks a metal rod or other material hammered into a tree truck either near the base of a tree where a logger or ...
Tree spiking was the act of inserting a metal spike in the base of a redwood tree thus making it impossible for loggers to cut down the tree without damaging or destroying their equipment. However, one event made environmental groups, including Earth First!, denounce tree spiking.
Tree spiking is a tactic used to deter logging by rendering a tree dangerous to cut, either by a lumberjack or in a sawmill, and is considered an act of eco-terrorism. At the friend's behest, Stone-Manning wrote an anonymous letter to federal officials, informing them of the tree spiking and warning that "a lot of people could get hurt" if ...
Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...
Although the word originally referred to the resinous exudate of terebinth trees (e.g. Chios turpentine, Cyprus turpentine, and Persian turpentine), [6] [7] it now refers to that of coniferous trees, namely crude turpentine (e.g. Venice turpentine is the oleoresin of larch), [8] or the volatile oil part thereof, namely oil (spirit) of ...
Brucine is an alkaloid closely related to strychnine, most commonly found in the Strychnos nux-vomica tree. Brucine poisoning is rare, since it is usually ingested with strychnine, and strychnine is more toxic than brucine. In chemical synthesis, it can be used as a tool for stereospecific chemical syntheses.
