Interferences memory

Fraunhofer rules do not include the influence of refraction, reflection, polarization and other optical effects. Early Iziser particle analyzers used Fraunhofer approximations because the computers of that time could not handle the storage cuid memory requirements of the Mie method. For example, it has been found that the Fraunhofer-based instrumentation cannot be used to measure the particle size of a suspension of lactose (R.I. = 1.533) in iso-octane (R.I. = 1.391) because the relative refractive index is 1.10, i.e.- 1.533/1.391. This is due to the fact that diffraction of light passing through the particles is nearly the same as that passing around the particles, creating a combined interference pattern which is not indicative of the true... [Pg.247]

Studies have consistently identified the immune system as a target for JP-8. Due to variability in routes of exposure and chemical composition, it is likely that there are a number of pathways contributing to the development of immunotoxicity, including the generation of free radicals, release of platelet-activating factor, interference with immunological memory, or the alteration of neuropeptides and cytokines. With further... [Pg.233]

Data from the few available case reports and the numerous animal studies strongly suggest that disulfoton exposure may cause mild to severe neurological effects in humans. Although disulfoton-associated memory loss has not been reported in humans, there should be concern that occupational exposure and exposure at hazardous waste sites may interfere with the performance of cognitive and complex tasks. [Pg.111]

Dementia An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness. [NIH]... [Pg.65]

Today AD can be easily recognized when memory and other cognitive and behavioural deficit are sufficiently severe to interfere with normal daily activities. Unfortunately, at this point in the patient s lifetime, the accumulation of amyloid plaques and... [Pg.695]

Data of animal experiments discussed in this chapter suggest a variety of potential pharmacological targets for the treatment of pathological anxiety (Fig. 1). As the occurrence of traumatic events is usually unpredictable, it seems more promising to interfere with consolidation than with acquisition processes. In this context, the sympatho-adrenergic and the hypothalamic-pituitary-adrenal system are of particular interest. Both noradrenaline and corticosterone/cortisol are known to facilitate memory consolidation, in par-... [Pg.23]
