| Parallel Electron Energy Loss Spectroscopy | <technique> Electron energy loss spectroscopy analyses the inelastically scattered electrons present in the beam after it has been transmitted through the sample. An electron energy loss spectrum typically consists of a monatomic decreasing background on which are superimposed a number of peaks. Each peak is characteristic of the scattering process that has occurred in the sample. The peaks can be used to obtain information about the chemical composition and electronic structure of the sample. Electron energy loss spectra are acquired typically in a magnetic sector spectrometer located under the camera chamber of the transmission electron microscope. Spatial resolution is typically limited by the minimum probe diameter of the microscope. Electron energy loss spectroscopy tends to be complimentary to EDS in that it can be used to analyse very thin samples of low Z materials. Acronym: PEELS (05 Aug 1998) |

| periodontal attachment loss | Loss or destruction of periodontal tissue caused by periodontitis or other destructive periodontal diseases or by injury during instrumentation. Attachment refers to the periodontal ligament which attaches to the alveolar bone. It has been hypothesised that treatment of the underlying periodontal disease and the seeding of periodontal ligament cells enable the creating of new attachment. (12 Dec 1998) |
| water loss, insensible | Loss of water by diffusion through the skin and by evaporation from the respiratory tract. It is so called because we do not know that we are actually losing water at the time that it is leaving the body. (guyton, textbook of medical physiology, 8th ed, p274) (12 Dec 1998) |
| conductive hearing loss | <otolaryngology> A form of deafness that results from a blockage of the ear canal or dysfunction of the ossicles or eardrum (sound collecting apparatus). In conductive hearing loss the auditory nerve is normal, but there exists a physical problem with the sound collecting apparatus. (05 Jan 1998) |
| hair loss | Hair loss may be associated with aging, hormones (androgens) or genetic predisposition. The pattern of baldness in women is different from that of men. In women there is thinning of the hair all over the scalp, but the frontal hairline is maintained. The hair loss is usually permanent. Treatment has been successful with topical minoxidil in some cases. (13 Nov 1997) |
| hearing loss, bilateral | Partial hearing loss in both ears. (12 Dec 1998) |
| hearing loss, central | Hearing loss due to central nervous system disease, anywhere in the auditory pathways from the cochlear nucleus of the pons to the auditory cortex. (12 Dec 1998) |
| hearing loss, conductive | Hearing loss due to interference with the acoustic transmission of sound to the cochlea. The interference is in the outer or middle ear. (12 Dec 1998) |
| hearing loss, functional | Hearing loss without a physical basis. (12 Dec 1998) |
| hearing loss, high-frequency | Hearing loss in frequencies above 1000 hertz. (12 Dec 1998) |
| hearing loss, noise-induced | Hearing loss from exposure to noise. The loss is often in the frequency range 4000-6000 hertz. (12 Dec 1998) |
| hearing loss, partial | A condition in which the sense of hearing, although defective, is functional with or without a hearing aid. The hearing level for speech is approximately 40-70 decibels I.s.o. (international organization for standardization) or 30-60 db a.s.a. (american standards association). (12 Dec 1998) |
| hearing loss, sensorineural | Hearing loss resulting from damage to the sensory mechanism internal from the oval and round windows. (12 Dec 1998) |
| sensorineural hearing loss | <neurology> A form of deafness that occurs due to dysfunction of the auditory nerve (cranial nerve VIII). (27 Sep 1997) |
| drift cyclotron loss cone instabilities | (DCLC) This is an electrostatic microinstability (frequencies at harmonics of the ion cyclotron frequency) which is of major concern in small mirror devices. Mode is driven by radial gradients in the electron density, and causes loss of ions due to non-conservation of magnetic moment (see adiabatic invariant) as they interact with the mode, and are dispersed in velocity space into the loss cone. Stabilisation is accomplished by increasing the plasma size and by partially filling the loss cone with a continuous extermal warm plasma stream. (09 Oct 1997) |
