Relative treatment-resistant

A partial answer to the first question has been provided by a theoretical treatment (1,2) that examines the conditions under which a matrix crack will deflect along the iaterface betweea the matrix and the reinforcement. This fracture—mechanics analysis links the condition for crack deflection to both the relative fracture resistance of the iaterface and the bridge and to the relative elastic mismatch between the reinforcement and the matrix. The calculations iadicate that, for any elastic mismatch, iaterface failure will occur whea the fracture resistance of the bridge is at least four times greater than that of the iaterface. For specific degrees of elastic mismatch, this coaditioa can be a conservative lower estimate. This condition provides a guide for iaterfacial desiga of ceramic matrix composites. 

TRD can best be conceptualized as occurring along a continuum rather than as an all or none phenomenon. Some patients have a relatively low level of therapy resistance, which can be easily handled in practice by straightforward clinical procedures other patients will follow a much more malignant course. From longitudinal studies (Keller et al. 1992), it is now clear that as many as 15% of patients with depression follow a long-term course and eventually become treatment resistant to almost all antidepressants. 

The electrical resistivity of the films (between 0.1 and 0.25 p.m thick), measured through Au contacts, was ca. 2.5 kfl/sq (ca. 5 X 10 fl-cm). This value increased with air-annealing (250°C, 20 min) up to 60 kfl/sq. The relatively low resistivity was attributed to incorporation of S, either from the Cu cS prelayer or by hydrolytic decomposition of 8203 to S . Treatment of the films with NaiS solution decreased the resistivity by nearly two orders of magnitude, and S was found in the films. It is likely that the surface of the CuiO crystals was partially... 

Two major problems complicating the question of treatment-resistant depression are inappropriate diagnosis and inadequate treatment (355). Studies have found only a small proportion (< 15%) of newly diagnosed depressed patients receive adequate antidepressant treatment as defined by dose and duration criteria (356, 357). Hence, a substantial number of treatment-resistant cases are actually the result of inadequate therapy (i.e., relative resistance). For example, in the MacEwan and Remick (358) study, 70% of those defined as treatment-unresponsive achieved complete remission with an adequate trial of an HCA, MAOl, or ECT. Patients who do not receive sufficient benefit from a trial of one antidepressant now have the option of newer agents whose activity does not necessarily overlap with earlier generation compounds (e.g., SSRIs, venlafaxine, nefazodone).

Thallium, bismuth, and lead based HTSCs are relatively degradation-resistant and are therefore convenient systems for conducting electrochemical changes in the oxygen stoichiometry. At the same time, physical properties of these materials are less exactly related to 6 because of the more complicated phase compositions of the corresponding systems. The electrochemical treatment of Bi-Pb cuprates in nitrate melts [297] makes it possible to vary 8 within the region of 0.1. 

This treatment proved to have a favorable effect on sticking problems and makes the surface relatively wear-resistant. Titanium can be applied in the same way in the form of TiN. This treatment leaves the tools in a bronzed appearance because the surface is... 

Since the typical imazalil-resistant isolate of P. digitatum showed a relatively low resistance level compared to Eenzimidazole-resistant isolates, experiments were conducted under practical operating conditions to determine the impact, if any, of these resistant isolates on the effectiveness of typical imazalil fruit treatments. Lemons were inoculated with isolates of P. digitatum, sensitive and resistant to imazalil (300 fruit each), and treated with this fungicide under usual practical conditions 1n a commercial packinghouse or in a pilot plant. The fruit were analyzed for... 

Treatment-resistant depression typically refers to an inadequate response to at least one antidepressant trial of adequate dose (superior to placebo in controlled clinical trials) and duration (e.g. 6-12 weeks). Treatment-resistant depression is a relatively common occurrence in clinical practice, with up to 50-60% of patients not achieving an adequate response following antidepressant treatment. Although the more traditional view of treatment resistance has focused on non-response, from the perspective of clinicians and patients, not achieving remission despite adequate treatment represents a significant challenge. In addition, response without remission has a potentially poor outcome, as residual symptoms are associated with poorer outcome and increased relapse risk. With this treatment approach in mind, inadequate response implies that the treatment has failed to achieve remission from the clinician s and patient s perspective, remission typically implies achieving a relatively asymptomatic state. ... 

Chemical Properties. The hydrolysis of PET is acid- or base-catalyzed and is highly temperature dependent and relatively rapid at polymer melt temperatures. Treatment for several weeks in 70°C water results in no significant fiber strength loss. However, at 100°C, approximately 20% of the PET tenacity is lost in one week and about 60% is lost in three weeks (47). In general, the hydrolysis and chemical resistance of copolyester materials is less than that for PET and depends on both the type and amount of comonomer. 

Steels iu the AISI 400 series contain a minimum of 11.5% chromium and usually not more than 2.5% of any other aHoyiag element these steels are either hardenable (martensitic) or nonhardenable, depending principally on chromium content. Whereas these steels resist oxidation up to temperatures as high as 1150°C, they are not particularly strong above 700°C. Steels iu the AISI 300 series contain a minimum of 16% chromium and 6% nickel the relative amounts of these elements are balanced to give an austenitic stmcture. These steels caimot be strengthened by heat treatment, but can be strain-hardened by cold work.
