Residual Phase

Decades after the onset of illness, some patients experience a distinct improvement and enter a residual phase of the disorder. In this phase, positive symptoms wane or disappear altogether. Negative symptoms, mood disturbance, and cognitive impairment may, however, persist. 

In the residual phase, the patient is unlikely to have an acute exacerbation even if (s)he stops taking an antipsychotic. Nevertheless, (s)he may still require treatment for residual symptoms. If medications are continued during a residual phase of schizophrenia, an atypical antipsychotic is preferred. Because positive symptoms are no longer a prominent aspect of the illness, there is usually little justification for using a typical antipsychotic and thereby exposing a patient to the risk of tardive dyskinesia. Moreover, atypical antipsychotics likely better treat the remaining negative symptoms of residnal schizophrenia.

A residual phase, usually consisting of insoluble fluorides and oxyfluorides of alkali earth and rare earth metals, is separated from the solution by filtration. The mechanism of the chemical decomposition of raw materials of the tantalum- and niobium-containing oxide type seems to be complicated, and unfortunately, the process has yet to be adequately investigated. 

In a discussion of these results, Bertrand et al. [596,1258] point out that S—T behaviour is not a specific feature of any restricted group of hydrates and is not determined by the nature of the residual phase, since it occurs in dehydrations which yield products that are amorphous or crystalline and anhydrous or lower hydrates. Reactions may be controlled by interface or diffusion processes. The magnitudes of S—T effects observed in different systems are not markedly different, which indicates that the controlling factor is relatively insensitive to the chemical properties of the reactant. From these observations, it is concluded that S—T behaviour is determined by heat and gas diffusion at the microdomain level, the highly localized departures from equilibrium are not, however, readily investigated experimentally. 

In reviewing reported values of E for calcite decompositions, Beruto and Searcy [121] find that most are close to the dissociation enthalpy. They suggest, as a possible explanation, that if product gas removal is not rapid and complete, readsorption of C02 on CaO may establish dissociation equilibria within the pores and channels of the layer of residual phase. The rate of gas diffusion across this barrier is modified accordingly and is not characteristic of the dissociation step at the interface.

Basic Principles of Operation Gas-separation literature often uses nomenclature derived from distillation, a practice that will generally be followed here. L is the molar feed rate, V is the molar permeate rate, R is the molar residue (L — V). Mole fractions of components i, j, in the feed-residue phase will be Xj, Xj. .. and in the permeate phase yi,yj.... Stage cut, 0, is permeate volume/feed volume, or V/L. 

Sequential extraction showed that, for both reduced and oxidized tailings, most of the total Fe (75-85%) is in the residual phase with most of the remainder in the iron-hydroxide phase. Less than 1% Fe is in the mobile adsorbed-exchangeable-carbonate and water soluble phases in both reduced and oxidized tailings. 

If that sort of simplistic model is acceptable, the extent of fractionation hints at rather small degrees of melting in the mantle and/or the presence of a residual phase that fractionates Sm from Nd, probably garnet, o... 

In summary, when undertaking a project such as the recovery of LNAPL, treatment of the coproduced water, prior to reinjection, may not be beneficial or technically necessary. A large percentage of the spilled or leaked petroleum hydrocarbon (40 to 60%) will be retained in the unsaturated zone as residual saturation. This residual hydrocarbon cannot be recovered by conventional withdrawal techniques. Without removing this continual source of contamination to the groundwater system, dissolved contamination will continue. Therefore, in most cases, it may be pointless and extremely costly to treat the coproduced groundwater prior to reinjection while the free- and residual-phase hydrocarbon contamination exists. 

When approaching the treatment of schizophrenia, it is best to view the illness in one of four distinct phases prodromal phase, acute phase, maintenance phase, and residual phase. Let us take a look at the treatment options at each of these phases of the illness. 

However, when there is clear evidence of persistent illness or when the patient endures several acute episodes of illness, treatment shonld be indefinite and probably lifelong. Except in the residual phases of illness, discontinuing antipsychotic medication exposes the schizophrenia patient to a serious risk of relapse. However, there is evidence that gradually decreasing the dose of antipsychotic in 4 week intervals can still provide good protection from relapse while lowering the risk of side effects.

Patients with this condition manifest the symptoms of an acute exacerbation of schizophrenia, with symptoms lasting at least one month, but they make a complete recovery, with the prodromal, active, and residual phases remitting in less than 6 months. 

In all experiments, we start with an in situ compensation of the residual spectral phase of the IR pump pulse, introduced by dispersive elements in the pump beamline. By this means, we make sure to have BWL pulses in the experiment if the zero phase is applied to the SLM. The residual phase is found by adaptive optimization of the total photoelectron yield from multiphoton ionization of ground state Xe atoms, which are led effusively into the interaction region. It turned out to be sufficient to parameterize the trial phase by a fifth-order polynomial. In the... 

Therefore, the residual phase shift of the MR signal for a magnetic moment undergoing uniform motion with velocity v for a set of bipolar gradients, +g, of duration 6 separated by a time A is - rg(5A (i.e., the measured phase shift is linearly proportional to the velocity). 

Pegmatites represent a residual phase of igneous depositions, characterized by extremely coarse crystalline material, that results Ironi the presence of associated volatiles, e.g.. water vapor, carbon dioxide, sulfur dioxide, and others, which decrease tile viscosity and facilitate crystallization. Quartz, feldspar, and mica are the more common minerals found in this environment. but Mich bodies are also hosts for many rare minerals and several types of gem stones, e.g.. beryl, tourmaline, and topaz.
