Dramatherapy and Psychodrama Definition of Dramatherapy: It could be argued that the above definition of dramatherapy could include psychodrama, an action method created by Dr. Moreno in the ss and now recognised internationally as a form of psychotherapy.
The new, powerfully radioactive substance could be concentrated with bariumbut, because its chloride was slightly more insoluble, it could be precipitated by fractional crystallization. The separation was followed by the increase in intensity of new lines in the ultraviolet spectrum and by a steady increase in the apparent atomic weight of the material until a value of Marie and Pierre Curie radium experimentDepiction of the paths of alpha, beta, and gamma particles from a radium sample placed between the poles of an electromagnet in an experiment conducted in Marie and Pierre Curie's laboratory, as drawn by Gaston Poyet, The long-lived radium is found in nature as a result of its continuous formation from uranium decay.
Since all the isotopes of radium are radioactive and short-lived on the geological time scaleany primeval radium would have disappeared long ago. Therefore, radium occurs naturally only as a disintegration product in the three natural radioactive decay series thoriumuraniumand actinium series.
Radium is a member of the uranium-decay series. Its parent is thorium and its daughter radon Compounds The chemistry of radium is what would be expected of the heaviest of the alkaline earthsbut Therapeutic recreation thesis intense radioactivity is its most characteristic property.
Its compounds display a faint bluish glow in the dark, a result of their radioactivity in which emitted alpha particles excite electrons in the other elements in the compound and the electrons release their energy as light when they are de-excited.
One gram of radium undergoes 3. This is an energy release equivalent to about 6. The practical energy release is even greater than this by four to five timesbecause of the production of a large number of short-lived radioactive decay products.
The alpha particles emitted by radium may be used to initiate nuclear reactions. The most important use of radium was formerly in medicineprincipally for the treatment of cancer by subjecting tumours to the gamma radiation of its daughter isotopes.
Radium, an alpha emitter with a half-life of In most therapeutic applications, however, radium has been superseded by the less costly and more powerful artificial radioisotopes cobalt and cesium An intimate mixture of radium and beryllium is a moderately intense source of neutrons and has been used for scientific research and for well logging in geophysical prospecting for petroleum.
For these uses, however, substitutes have become available. One of the products of radium decay is radonthe heaviest noble gas ; this decay process is the chief source of that element.
When a radium salt is mixed with a paste of zinc sulfide, the alpha radiation causes the zinc sulfide to glow, yielding a self-luminescent paint for watch, clock, and instrument dials.
From about up until the s, several million radium dials, coated with a mixture of radium and zinc sulfide, were manufactured. By the early s it was found, however, that exposure to radium posed a serious hazard to health: Like calcium and strontiumradium tends to concentrate in boneswhere its alpha radiation interferes with red corpuscle production, and some of those women developed anemia and bone cancer.
The practice of employing radium in luminescent coatings was curtailed in the early s after the high toxicity of the material was recognized. Phosphorescent paints that absorb light and later release it have replaced radium. The detection of exhaled radon provides a very sensitive test for radium absorption.
Radium metal may be prepared by electrolytic reduction of its salts, and it displays high chemical reactivity. It is attacked by water with vigorous evolution of hydrogen and by air with the formation of the nitride. The sulfate, RaSO4, is the most insoluble sulfate known, and the hydroxide, Ra OH 2, is the most soluble of the alkaline-earth hydroxides.
The gradual buildup of helium within crystals of radium bromide, RaBr2, weakens them, and they occasionally explode. In general, the compounds of radium are very similar to their barium counterparts, making separation of the two elements difficult.
In modern technologyradium is separated from barium by fractional crystallization of the bromides, followed by purification through ion-exchange techniques for removal of the last 10 percent of the barium.To call Joaquin Phoenix one of our greatest living shape-shifters is to do more than acknowledge his range.
It’s also a good way to describe the bold physicality of his transformations—how he. Cerebral Palsy and Therapeutic Riding. Reprinted from NARHA Strides magazine, October (Vol. 1, No. 1) Cerebral palsy is a condition caused by damage to the brain, usually occurring before, during or shortly following birth.
Definition of Dramatherapy: The UK Health Professions Council Standards of Proficiency for Arts Therapists document () describes Dramatherapy as. The Ridges, formerly called the Athens Lunatic Asylum, was a mental hospital operated in Athens, Ohio from until During its operation, the hospital provided services to a variety of patients including Civil War veterans, children, and violent criminals suffering from various mental disabilities.
