Physical and Chemical Restraints

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 Chemistry and Chemical Physics: A survey

2013
What is the subject of physical chemistry? How is this discipline structured and what are its sub divisions? How did this discipline evolve and what are its current hot topics? Answers to these and some other questions will be given in this brief overview article which also provides links for further reading.

Automated exploration of the low-energy chemical space with fast quantum chemical methods.

Physical Chemistry, Chemical Physics - PCCP, 2020
We propose and discuss an efficient scheme for the in silico sampling for parts of the molecular chemical space by semiempirical tight-binding methods combined with a meta-dynamics driven search algorithm.

Physics-Informed Neural Networks with Hard Linear Equality Constraints

Computers and Chemical Engineering
Surrogate modeling is used to replace computationally expensive simulations. Neural networks have been widely applied as surrogate models that enable efficient evaluations over complex physical systems.

Chondronectin: Physical and chemical properties

Archives of Biochemistry and Biophysics, 1985
Chondronectin, the chondrocyte attachment factor, was purified from chicken serum and characterized as to its physical and chemical properties. From sedimentation equilibrium data it was found to have a native molecular weight of 175,800 +/- 800 and a subunit molecular weight of 55,540 +/- 800 in the presence of guanidinium chloride and cysteine ...

Physical and Chemical Restraints (an Update)

Emergency Medicine Clinics of North America, 2020
Violent, combative and intoxicated patients are a common problem in the emergency department, and the emergency physician must be prepared to control the situation safely and effectively when a patient begins to exhibit dangerous behavior. This article reviews initial de-escalation techniques to reduce the need for patient restraint.

Physical-chemical properties of ubiquitin

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1980
The secondary structure of ubiquitin, the environment of its single tyrosine residue and its potential for interacting noncovalently with histone 2A or DNA, have been probed by circular dichroism (CD), ultraviolet absorbance, fluorescence and ancillary techniques.

Chemical and physical properties of radionuclides

International Journal of Radiation Applications and Instrumentation. Part B. Nuclear Medicine and Biology, 1987
There are many radionuclides with a wide range of energies and half-lives available for use as non-sealed radiotherapeutic agents. To date, no single radionuclide has emerged as being clearly superior to all others, in the way that 99mTc predominates in diagnostic imaging. It is unlikely that one will emerge.
