Multiphase TRIP-assisted steels are particularly interesting for the automotive industry, as they exhibit an exceptional strength-ductility balance due to the combination of a multiphase microstructure and the mechanically-induced transformation of metastable austenite to martensite (i.e. the TRIP effect). The multiphase microstructure - and the retention of metastable austenite - is achieved through the combination of appropriate chemistry and heat treatment conditions, i.e. an intercritical anneal followed by an isothermal dwell in the temperature range for bainite formation. The present work focuses mainly on the effect of heat treatment conditions that are compatible with CGL process, i.e. a high bainitic dwell temperature, on the microstructure and mechanical properties of two TRIP-assisted steel grades differing by their silicon and aluminium contents. It has thus been established that it seems easier to retain austenite when Si is replaced by Al, and more particularly that it was possible to retain a significant amount of austenite in a mixed 0.5Al-1.0Si grade, and hence to observe a TRIP effect. On the other hand, a Si-alloyed grade did not exhibit a significant retention of austenite, possibly due to carbide precipitation. It has also be seen that the intercritical annealing temperature has a strong influence on the amount of austenite that can ultimately be retained after the bainitic dwell, possibly by affecting the C content in the intercritical austenite.

Background: We previously reported that treatment of patients with symptomatic advanced non-small cell lung cancer with single agent Gemcitabine (GEM) resulted in a superior clinical-benefit response rate (RR) compared to cisplatin-based combination chemotherapy. We now report the detailed individual symptom control analysis, and the influence of cisplatin-use, age, performance status (PS) and duration of treatment. Patients and methods: Patients received either GEM (1000 mg/m(2), days 1, 8 and 15) or cisplatin (100 mg/m(2), day 1) plus Vindesine (3 mg/m(2), days 1 and 15) (PV), both every 4 weeks. Scores of 9 symptoms were listed weekly by the patient on visual analogue scales. Improvement of a symptom was defined as 2 consecutive cycles of improvement over baseline. Results: Baseline symptoms in the 169 patients were well balanced between the 2 arms (84 GEM, 85 PV). Both patients with objective response and disease stabilisation had clearly better symptom control than those with disease progression. Symptom control in both arms was similar for 'disease-specific' symptoms such as cough, dyspnea, pain or haemoptysis. Compared to PV, a significantly larger number of GEM-patients had better scores for 'constitutional' items such as anorexia (P = 0.007), ability to carry on with daily activities (P = 0.04) and overall impression of quality-of-life (P = 0.008). Symptom control was very similar in younger (< 65 years) versus older (> 65 years) patients, and only slightly better in those with a Karnofsky PS greater than or equal to 80% compared to those < 80%. Most of the symptom improvement occurred in the first 3 cycles, with some further symptom improvement in the following cycles in the GEM-arm only. Conclusions: Both GEM and PV yield a symptom control rate much higher than expected by the objective tumour RR. GEM is equally effective in controlling 'disease-specific' symptoms, but superior in controlling 'constitutional' symptoms. Most of the symptom control was achieved during the first 3 cycles of treatment, with some further improvement thereafter in the GEM-arm only. (C) 2002 Elsevier Science Ireland Ltd.

Dynamical tunneling between symmetry-related stable modes is studied in the periodically driven pendulum. We present strong evidence that the tunneling process is governed by nonlinear resonances that manifest within the regular phase-space islands on which the stable modes are localized. By means of a quantitative numerical study of the corresponding Floquet problem, we identify the trace of such resonances not only in the level splittings between near-degenerate quantum states, where they lead to prominent plateau structures, but also in overlap matrix elements of the Floquet eigenstates, which reveal characteristic sequences of avoided crossings in the Floquet spectrum. The semiclassical theory of resonance-assisted tunneling yields good overall agreement with the quantum-tunneling rates, and indicates that partial barriers within the chaos might play a prominent role.

High workability together with a good resistance to segregation is needed for cement based composites, specifically fresh Self-Compacting Mortars (SCM); in this prospect, the amount of coarse materials has to be reduced and replaced by fine material. Several limestone fillers are here compared and analysed. These by-products are issued from different industrial sectors, such as the aggregate and lime production industry (quarrying operations) and the ornamental stones industry (sawing operations). Particular attention has been paid to clay content, as consistency of fresh mortars was varying, while other physical characteristics like granulometry remained the same. Relationship between the physico-chemical properties of the fillers and the properties of fresh and hardened mortars are brought forward. Even if it may affect fresh properties of mortars, results clearly show that clay type and content has minor influence than limestone filler itself. [less ▲]

Eight kinds of typical coal samples were chosen for studying the influence of coal characteristics on laser—induced plasmas.Element analysis and industry analysis were carried out for every sample.Experimental study on the interaction between laser and different coal samples was completed,and factors affecting laser plasma were analyzed,such as coal moisture and coal dust.The experiment result indicates that the coal samples with different coalification degrees have different plasma time—resolved spectral characteristics,all of them tend to rise at the beginning of plasma formation (< 1us),then with the decay of plasmas emission.they tend to decrease in about 1us,while secondary ionization occurs in highly coalificated coals after 2 us.The plasma temperature differs from one kind to another,the higher the coalification degree is,the higher the plasma temperature will be.

Nowadays, polymers are a part of everyday life. Researchers encouraged by growing need in high performance polymers develop new synthesis tools to manage the molecular architecture and thus the polymer properties. In this context, CRP (Controlled Radical Polymerization) techniques have been developed to obtain well-defined architectures and to control polymer parameters. Among these systems is Cobalt-Mediated Radical Polymerization (CMRP), which is based on the reversible deactivation of the growing radical chains with a cobalt complex, the cobalt (II) bis-acetylacetonate. The interest of this system is not only due to its ability to control the polymerization of very reactive monomers such as vinyl acetate (VAc) and N-vinylpyrrolidone (NVP), but also its peculiar mechanism which exhibits two pathways depending on the polymerization conditions; a reversible termination process and a degenerative chain transfer mechanism. Furthermore, it has been showed that the Co-C strength and thus the polymerization are strongly influenced by the use of some additives, such as water, dimethylformamide, dimethylsulfoxide and pyridine, which coordinate the cobalt free site. In this presentation we report the use of a preformed alkyl-cobalt(III) adduct as initiator for the polymerization of acrylonitrile (AN) and the use of these ligands in the CMRP system to synthesize well-defined poly(vinyl acetate)-b-poly(acrylonitrile) block copolymers. As a conclusion, cobalt-coordination appears today as a unique opportunity to adjust the Co-C bond strength and to push back the bounds of possibilities in terms of macromolecular engineering assisted by CMRP.

OBJECTIVE: To investigate whether colored glasses influence the habituation of visual evoked potentials. BACKGROUND: We have previously shown that during pattern-reversal stimulations lasting 2 minutes the amplitude of the visual evoked potential increases in migraine with and without aura between attacks, whereas it decreases in healthy volunteers. Red light was found to increase visually evoked EEG fast activity only in children with migraine with aura. Wearing rose-tinted glasses for 4 months decreased attack frequency in parallel with a reduction of the visually evoked EEG fast activity. METHODS: We compared the change in amplitude of the visual evoked potential using five different tinted glasses in 12 patients with migraine with aura and in 10 healthy volunteers. During continuous stimulation at 3.1 Hz, five blocks of 50 responses were sequentially averaged using red, yellow, green, blue, and grey glasses and without glasses in a random order and analyzed in terms of latencies and N1-P1 amplitudes. Amplitude changes were calculated for each block by comparison with the first block in every condition and analyzed statistically using Zerbe's method. RESULTS: In healthy volunteers, the visual evoked potential amplitude increased with red glasses compared to without glasses (P = .05) or with green glasses (P = .03). In patients with migraine with aura, no significant difference was detected using colored glasses. Our findings in healthy volunteers are in line with earlier reports of increased excitability of the human visual cortex when exposed to red light. The lack of such a pattern in patients with migraine with aura suggests that the visual cortex is interictally hypoexcitable rather than hyperexcitable, which is consistent with studies of transcranial magnetic stimulation.
