Physical and Chemical Restraints [PDF]

open access: possibleEmergency Medicine Clinics of North America, 2009
The combative or uncooperative patient is a growing problem in the emergency department. Restrained patients are at especially high risk of adverse outcomes. Particular attention has been given to de-escalation techniques to reduce the need for patient restraint. This article examines these techniques and the need for and risks of physical and chemical

Physical, Chemical, and Chemical−Physical Double Network of Zwitterionic Hydrogels

The Journal of Physical Chemistry B, 2008
Zwitterionic hydrogels are very promising for biomedical applications. They are usually copolymerized with other polymers to improve their mechanical properties often at the expense of their biological properties. In this study, physically cross-linked poly(sulfobetaine methacrylate) (polySBMA) hydrogels were prepared, and their physical properties ...

Physical and Chemical Mutagenesis

2003
Important methods to artificially induce mutations are the use of chemical and physical agents. Most chemical mutagens are alkylating agents and azides. Physical mutagens include electromagnetic radiation, such as gamma rays, X rays, and UV light, and particle radiation, such as fast and thermal neutrons, beta and alpha particles.

Physical-Chemical Properties [PDF]

open access: possible, 1987
Among the nucleic acids, the single-stranded RNA molecules have the highest potential to form a large variety of structures and to undergo quite different structural transitions. The determination of their structure and structural transitions is a prerequisite for understanding their function in replication, transcription, translation, and regulation ...
