Physical and Chemical Restraints [PDF]

Emergency 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 and Chemical Weathering

2015
As one geologist exclaimed: “Savor the irony should the metamorphic muscles that push mountains to the sky be driven by the pitter patter of tiny raindrops.” In the following chapters we look at this pitter patter, a synonym for exogenic processes that shape our landforms, starting with the most important process: weathering.

Physical and Chemical Sensors

2011
In this chapter we give an introduction and classification on some examples of physical sensors (devices placed at the input of an instrumentation system that quantitatively measures a physical parameter, for example pressure, displacement or temperature) and chemical sensors (devices which are part of an instrumentation system that determines ...

Chemical and Physical Bonding

1995
Electron Pair Orbitals. A practical understanding of ceramic processing requires some knowledge of chemical bonding. Weak bonds, strong bonds, and some bond types not ordinarily emphasized in first year chemistry courses are all involved in a typical ceramic process, even for an old method such as the slip casting of ball clay.

Chemical and physical qualities

International Journal of Food Science & Technology, 1968
One of the main purposes of quality control is the economical production of standardized products which show the minimum variation from one day to the next. In formulating products various factors have to be considered such as relevant legal and specification requirements, organoleptic acceptability and changes which take place during processing and ...
