Rationale for Use

The rationale for using a hydrogen fuel cell is that the cell reaction produces only water. 

NOTE The original rationale for using coordinated phosphate programs was to control under-deposit chemistry, not to minimize the presence of the deposits themselves. 

Describes equipment such as compressor, filter, tubing, aerosol cup, and mask or mouthpiece to be used for therapy, including rationale for use and need for electrical power source.

Liotrix is a fixed-ratio LT4/T3 product, although the LT4 T3 ratio is not physiologic for humans. Several studies have been published that evaluate the use of LT4 and T3 combinations in ratios that mimic human physiology. While early studies with these combinations showed improved neuropsychiatric and quality-of-life outcomes compared with LT4 monotherapy, subsequent randomized, controlled trials have shown no outcome benefit.13 Except in rare circumstances (such as patients with impaired T4-to-T3 conversion), there is no rationale for using combinations of LT4 and T3 to treat hypothyroidism. 

Explain the rationale for using hematopoietic cell transplant (HCT) to treat cancer. 

The second case assumed kl = 1. The rationale for using this form for Eq. (7) comes from the observation that in conventional spouted beds, used by Liu and Litster (1993a), the times for particles of different mass to circulate through the spray zone were not the same. In fact, Robinson and Waldie (1978) found that for a conventional spouted bed ... 

The observed hypermotility of the sigmoid colon in many symptomatic patients provides the rationale for using anticholinergic drugs and spasmolytic agents [25]. However, the efficacy of these agents has never been clearly documented in randomized controlled trials [3,24],... 

Antibiotics are commonly used in the treatment of inflammatory complications of diverticular disease [3, 24]. In painful diverticular disease, when inflammation is excluded by definition, there is no rationale for using antibiotics. In a subset of patients with more severe symptoms, when an inflammatory component may be clinically suspected, a short course of antibiotics may be advisable [15],... 

An important methodologic point about the majority of these studies is that they use a reduced preparation, in which the spinal cord is neurally isolated from the brain by a complete transection (129). The rationale for using this simplified preparation is that spinal reflex activity can be analyzed in the absence of supraspinal influences. However, transection may introduce other variables (i.e., ischemia, disruption of the blood-brain barrier, loss of tonic neural activity from supraspinal systems), which may result in drug effects on spinal reflexes that are quantitatively or even qualitatively different than those seen in the intact animal. Thus the following review of hallucinogen effects on spinal reflexes is organized into two main categories (a) studies in transected animals, and (b) those in decerebrate or intact preparations. 

Many spectra are shown to support the authors conclusions, as are tables. The rationale for using particular peaks is accompanied by R2, SEC, and SEP for the equation developed from that wavelength or region. The sheer number of data prohibits even a summary in this chapter. The reader is directed to the paper for actual values. The soundness of the developed equations does seem to justify the authors assignments of wavelengths to various components. 

The rationale for using low degree polynomials to approximate / is based on a Taylor series expansion off around x=0. 

Cholinesterase inhibitors cross the blood-brain barrier and decrease enzymatic hydrolysis of acetylcholine in the synaptic cleft, thereby increasing acetylcholine availability for neurotransmission. The rationale for using cholinergic agents to treat Alzheimer s disease stems from evidence of decreased cerebral choline acetyltrans-ferase (the enzyme responsible for acetylcholine synthesis) and cholinergic neuron loss in the nucleus basalis of Meynert, which correlate with plaque formation and cognitive impairment (Arendt et al. 1985 Davies and Maloney 1976 Etienne et al. 1986 Perry et al. 1978b). 

Only a few acidic baths have been described (see also sections 4.1.6.6 and 4.1.6.7 below). In one, thiosulphate was used at apH of between 2 and 4 and a temperature of 85°C [131]. The bandgap was 2.35 eV and the resistivity 10" -10 fl-cm. Thioacetamine has also been used at a pH of 5 [8]. The films from this bath were clearly hexagonal. The rationale for using an acid bath is to prevent the formation of hydroxy species this is a major problem forZnS but much less so for CdS. 

This a a2-noradrenergic presynaptic receptor agonist is approved by the FDA as an antihypertensive. The rationale for using clonidine for mania is based on the original catecholamine hypothesis (21, 22), which postulates a hyperfunctionality of the noradrenergic system predisposing to mania. Because the hypothesis... 

One rationale for using the B6C3F1 mouse is that 75-80 percent survive to the end of a typical two-year study.
