Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
Pethidine is indicated for the treatment of moderate to severe pain, and is delivered as a hydrochloride salt in tablets, as a syrup, or by intramuscular, subcutaneous, or intravenous injection. For much of the 20th century, pethidine was the opioid of choice for many physicians; in 1975, 60% of doctors prescribed it for acute pain and 22% for ...

[2] [3] It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9234.
Imazapic is the herbicide most widely used by land managers for B. tectorum control. Of the herbicides listed it is also the most commonly studied. Imazapic is preferred because it can be applied both pre and post-emergence, is approved for rangeland use, and has residual soil activity that allows for one to two year control. [30]
Thinopyrum intermedium is a perennial plant, which means that usual methods of disease management used for annual grain production might not be applicable and efficient. Also, common herbicides used in annual grain cultivation are not approved for use with intermediate wheatgrass. Therefore, different approaches are necessary to disrupt ...
