| thermal barrier | <radiobiology> In magnetic mirror devices, this is a depression of electrostatic potential formed by enhancing ion loss in the region between the central cell and the positive potential plug. The thermal barrier significantly reduces the density requirements in the plug and lowers the overall power required to sustain the solenoidal plugging by thermally decoupling central cell electrons from the end plugs.

| radiation-protective agents | Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. Military, purposes. (12 Dec 1998) |
| gloves, protective | Coverings for the hands, usually with separations for the fingers, made of various materials, for protection against infections, toxic substances, extremes of hot and cold, radiations, water immersion, etc. The gloves may be worn by patients, care givers, housewives, laboratory and industrial workers, police, etc. (12 Dec 1998) |
| respiratory protective devices | Respirators to protect individuals from breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors. (12 Dec 1998) |
| head protective devices | Personal devices for protection of heads from impact, penetration from falling and flying objects, and from limited electric shock and burn. (12 Dec 1998) |
| protective | <pharmacology> An agent that affords defense against a deleterious influence, such as a substance applied to the skin to avoid the effects of the sun's rays or other noxious influences. Origin: L. Protegere = to cover over (18 Nov 1997) |
| protective agents | Synthetic or natural substances which are given to prevent a disease or disorder or are used in the process of treating a disease or injury due to a poisonous agent. (12 Dec 1998) |
| protective block | An incompletely understood mechanism whereby a pacemaker is protected from being discharged by the impulse from another centre; the mechanism, usually conceived as an encircling zone of unidirectionally refractory tissue permitting egress of impulses from the centre but preventing access to the centre, is seen in operation in ventricular parasystole where the parasystolic centre is protected from discharge by the sinus pacemaker and so is able to maintain its intrinsic rhythm undisturbed. Synonym: entrance block, protection. (05 Mar 2000) |
| protective clothing | Clothing designed to protect the individual against known hazards to which he will be exposed. (12 Dec 1998) |
| protective colloid | A colloid that has the power of preventing the precipitation of suspensoids under the influence of an electrolyte. (05 Mar 2000) |
| protective devices | Devices designed to provide personal protection against injury to individuals exposed to hazards in industry, sports, aviation, or daily activities. (12 Dec 1998) |
| protective laryngeal reflex | Closure of the glottis to prevent entry of foreign substances into the respiratory tract. (05 Mar 2000) |
| protective protein | An immunoglobulin molecule that has a specific amino acid sequence by virtue of which it interacts only with the antigen that induced its synthesis in cells of the lymphoid series (especially plasma cells) or with antigen closely related to it. Antibodies are classified according to their ode of action as agglutinins, bacteriolysins, haemolysins, opsonins, precipitins, etc. (18 Nov 1997) |
| protective spectacles | Spectacles which protect against ultraviolet or infrared rays or against mechanical injuries. Synonym: safety spectacles. (05 Mar 2000) |
| protective zone | The time in the cardiac cycle, immediately following the vulnerable period, during which a second stimulus will prevent the initiation of ventricular fibrillation by a previous stimulus applied during the vulnerable period, probably by blocking a reentrant pathway.
