A theory of crack healing in polymers is presented terms the stages healing, namely, (a) surface rearrangement, (b) approach, (c) wetting, (d) diffusion, and (e) randomization. The recovery ratio R mechanical properties with time was determined as a convolution product, = Rh (t)*φ(t), where (t) an intrinsic function, φ(t) wetting distribution function for interface or plane material. reptation model chain tube used to describe self-diffusion interpenetrating random coil chains which formed...
<h3>Background</h3> Although electroconvulsive therapy (ECT) has been shown to be extremely effective for the acute treatment of major depression, it never systematically assessed as a strategy relapse prevention. <h3>Objective</h3> To evaluate comparative efficacy continuation ECT (C-ECT) and combination lithium carbonate plus nortriptyline hydrochloride (C-Pharm) in prevention depressive relapse. <h3>Design</h3> Multisite, randomized, parallel design, 6-month trial performed from 1997...
Consider a ring of N qubits in translationally invariant quantum state. We ask to what extent each pair nearest neighbors can be entangled. Under certain assumptions about the form state, we find formula for maximum possible nearest-neighbor entanglement. then compare this with entanglement achieved by ground state an antiferromagnetic consisting even number spin-1/2 particles. that, though typically does not maximize relative all other states, it so states having zero z component spin.
OBJECTIVE: This study assessed the incidence, severity, and course of expressed suicidal intent in depressed patients who were treated with ECT. The data are from first phase an ongoing, collaborative multicenter study, overall aim which was to compare continuation ECT pharmacotherapy prevention relapse after a successful METHOD: Suicidal intent, as by during interview, scored at baseline before each session item 3 on 24-item Hamilton Depression Rating Scale 444 unipolar depression. RESULTS:...
Abstract We propose that crack healing in polymers occurs by the stages of surface rearrangement, approach, wetting, diffusion, and randomization. The wetting diffusion are responsible for majority mechanical property recovery or healing, control intrinsic function R h (t). However, observed macroscopic is a convolution product (t) distribution Φ(t). Each contains component. Experiments were designed to investigate functions fracture stress, strain, energy; results found be excellent...
Objective: We sought to examine the relationship of seizure threshold (ST) age and other demographic characteristics in a large sample where ST was determined by dose titration (DT) method. also compared resulting stimulation levels estimates predicted an age-based formula, half-age (HA) Methods: In multicenter prospective study, patients received standardized course bilateral electroconvulsive therapy for major depression using brief pulse device. The at first treatment fixed algorithm...
Abstract Craze healing was observed in many amorphous glassy polymers. A detailed study of the kinetics craze atactic polystyrene ( M w = 255,000) conducted. The crazes were created 0.08 mm films air at room temperature, T o , and constant stress, σ ⋍ 2,300 psi, healed temperature h for a time, 0, recrazed . Nucleation times, τ 1 2 growth rates, L first second loading, respectively, measured as function t individual using dark field optical microscopy. Complete mechanical ⩾ 70°C( g ≅ 100°C)....
"Two quantum dots, both alike in composition, but differing structure, where we lay our scene, From broader classes, to bring deeper understanding, the crystalline core that drives dot's sheen." In this contribution examine two families of silicon dots (SiQDs) mind Capulets and Montagues Shakespeare's Romeo Juliet because their stark similarities differences. SiQDs are highly luminescent, heavy-metal-free, based upon earth-abundant elements. As such, they have attracted attention for...
Objective: To determine the relationship between baseline melancholic features with outcomes in patients major depressive disorder referred for electroconvulsive therapy (ECT). Method: In a multihospital (Consortium Research ECT) collaborative ECT study, SCID-1 interviews were obtained at study entry. Ratings of 24-item Hamilton Rating Scale Depression thrice weekly during course ECT, once subsequent treatment-free week, and periodically 6-month continuation treatment either bitemporal or...
Care of casualties in the tactical combat environment should include use prophylactic antibiotics for all open wounds. Cefoxitin was antibiotic recommended 1996 article "Tactical Combat Casualty Special Operations." The present authors recommend that oral gatifloxacin be choice because its ease carriage and administration, excellent spectrum action, relatively mild side effect profile. For those unable to take unconsciousness, penetrating abdominal trauma, or shock, cefotetan is longer...
The effects of silicon monoxide evolution on mixtures and silica are examined from a materials perspective.
Void formation is shown to be a significant response of styrene-isoprene-styrene block copolymers under conditions tensile stress relaxation. When brought zero stress, these voids are observed close and heal, restoring the original mechanical properties undamaged material. Dark-field optical microscopy light-transmission photometry have been used study void healing in size regime appropriate techniques. As meaured from reference state damage, was found increase with time temperature...
The seizure threshold (ST) is a measure of the minimum electrical energy necessary to induce grand mal seizure. Dose titration ST has been suggested optimize stimulus dosing in electroconvulsive therapy (ECT). change with remission examined large sample unipolar depressed patients.In study continuation treatments after successful ECT, was determined at first treatment and again 1 week using conventional measurement protocol. Patients were treated bilateral electrode placement 150% above...
Abstract Objective Parkinson's disease psychosis ( PDP ) is a frequent complication of idiopathic iPD with significant impact on quality life and association poorer outcomes. Atypical antipsychotic drugs APD s) are often used for the treatment ; however, their use complicated by adverse drug reactions ADR s). In this study, we present patients who were treated most commonly atypical agents review respective s. Methods A retrospective study was carried out to include total 45 visited movement...
CoNi nanoparticle-decorated hollow carbon cubes (CoNi-HCCs) were synthesized using ZIF-67 as a sacrificial template. The synthesis utilizes the thermal instability of ZIF-67, creating nanostructures while facilitating carbonization and introducing metal nanoparticles (e.g., CoNi). Prototype Zn–air batteries equipped with CoNi-HCCs exhibited promising discharge potential 1.21 V charge 2.04 at 20 mA cm–2. These values are superior to those Pt–Ru, whose potentials 1.20 2.08 V, respectively....
Abstract We have investigated the role of chain scission in glassy polymers by monitoring molecular weight changes induced microtoming thin slices monodisperse polystyrenes. The number‐average allow determination N f , number bond scissions per unit area. It is found that independent initial and has value 6.50 × 10 13 scissions/cm 2 at room temperature; decreases with increasing temperature, suggesting pullout increases temperature. work required to create surface area polystyrene several...
In this study supercritical fluids were used to process several different types of oligomers. Supercritical fluid processing was found be quite effective at removing low vapor pressure monomers from polymers and for fractionation according molecular weight. This resulted in high purity materials with M̄w/M̄n ratios. The polymer fractions obtained analyzed by size exclusion chromatography, differential scanning calorimetry, melt rheometry. Their physical chemical properties are described.
