Středa [10] also reported the percentage composition of the reaction mixture after its removal from the ammunition body after three months. Key components included 1.9–2.9% diisobutyl methylphosphonate, 0.5–0.7% isobutyl alcohol, 23–25% 2-(diethylamino)ethanethiol, 26–28% isobutyl methylphosphona...
but it was found to just be two pigmented molecules which have two functions for the hippo, being a sunscreen, and an antibiotic. It has been found that the main components aren't secreted as most sweat components are, but secreted in subdermal glands, making the classification of the sweat...
Surprisingly, the chemical profile of the lesion tissue was clearly different from those of the other two zones and healthy leaves from a non-infected plant (CON) (Fig. 1b). The main components identified in healthy leaves and lesion tissue were designated compounds 1–4 and 1a–4a, ...
A technical system usually consists of a number of subsystems and components connected in such a way that the system is capable of performing a number of required functions. Very often, the subsystems and components that make up the system are of different technologies, which increase the comple...
(usually the latter) between the components of such systems, or between such systems and their surroundings, and are usually caused by the addition of new substances, which themselves have energy and which therefore disrupt energy balances or remove energetic constraints. Most chemical processes ...
The mixture was then stirred at room temperature for 8 hours before being evaporated to dryness and the residue separated into basic and non-basic components using SCX chromatography. Basic fractions were combined and evaporated to dryness. The residue was purified by RPHPLC (MeCN with NH3 buffer...
