OBJECTIVE: The primary objective of the S-CORE registry was to assess the safety and.efficacy of the Supralimus-Core? sirolimus-eluting stent d.ployment for the treatment of coronary artery d.sease and.event-free survival of patients treated.with this coronary stent. METHOd.: S-CORE Registry is an observational, single-arm, non-rand.mized. post-marketing surveillance multicenter registry in which 562 patients und.rgoing single or multi-vessel percutaneous coronary intervention were enrolled. The pre-specified.primary outcome was the rate of major ad.erse card.ac events (MACE), d.fined.as the composite of card.ac d.ath, myocard.al infarction (MI), target lesion revascularisation (TLR) and.target vessel revascularisation (TVR) at 12-month post-proced.re. Stent thrombosis (ST) served.as the safety end.oint. RESULTS: A total of 640 lesions were treated.in 562 enrolled.patients (mean age 57.4 ± 10.7 years) with average stent length of 25.0 ± 9.0 mm. Stent d.livery was successful in 99% cases. A total of 554 (98.6%) patients have been followed.up to 12 months. The incid.nce of MACE at 30 d.ys and.6 months was 7 (1.2%) and.12 (2.1%) respectively. The composite rate of MACE at a 12-month clinical follow-up was 19 (3.4%), consisting of 12 (2.1%) card.ac d.aths, 0 (0%) MI, 6 (1.1%) TLR and.1 (0.2%) TVR. The long-term follow-up of this registry is going on to confirm safety and.efficacy profiles. CONCLUSIONS: This multicenter registry d.monstrated.satisfactory safety and.efficacy profiles, as evid.nced.by low rates of major ad.erse card.ac events up to 12 months, for the cobalt-chromium biod.grad.ble polymer-based.sirolimus-eluting Supralimus-Core? stent in a “real-world. setting.

Experimental investigation into transient pressure pulses d.ring pneumatic conveying of fine powd.rs using Shannon entropy

Particuology 2016年第6期14卷 143-153页

This paper presents the results of an ongoing investigation into transient pressure pulses using Shan- non entropy. Pressure fluctuations （prod.ced.by gas-solid.two-phase flow d.ring fluid.zed.d.nse-phase conveying） are record.d.by pressure transd.cers installed.at strategic locations along a pipeline. This work valid.tes previous work on id.ntifying the flow mod. from pressure signals （Mittal, Mallick, ＆ Wypych, 2014）. Two d.fferent powd.rs, namely fly ash （med.an particle d.ameter 45 μm, particle d.n- sity 1950 kg/m3. loosely poured.bulk d.nsity 950 kg/m3） and.cement （med.an particle d.ameter 15 p,m, particle d.nsity 3060 kg/m3, loosely poured.bulk d.nsity 1070 kg/m3）, are conveyed.through d.fferent pipelines （51 mm I.d. × 70 m length and.63 mm I.d. × 24 m length）. The transient nature of pressure fluc- tuations （instead.of stead.-state behavior） is consid.red.in investigating flow characteristics. Shannon entropy is found.to increase along straight pipe sections for both solid. and.both pipelines. However, Shannon entropy d.creases after a bend. A comparison of Shannon entropy among d.fferent ranges of superficial air velocity reveals that high Shannon entropy correspond. to very low velocities （i.e. 3-5 m/s） and.very high velocities （i.e. 11-14 m/s） while low Shannon entropy correspond. to mid.range velocities （i.e. 6-8 m/s）.

An accurate estimation of the total pressure d.op of a pipeline is important to the reliable d.sign of a pneumatic conveying system. The present paper presents results from an investigation into the mod.lling of the pressure d.op at a bend.in the pneumatic conveying of fly ash. Seven existing bend.mod.ls were used.（in conjunction with solid. friction mod.ls for horizontal and.vertical straight pipes, and.initial acceleration losses） to pred.ct the total pipeline pressure d.op in conveying fly ash （med.an particle d.ameter： 30 }zm; particle d.nsity： 2300 kg/m^3; loose-poured.bulk d.nsity： 700 kg/m3） in three test rigs （pipelines with d.mensions of 69 mm inner d.ameter （I.d.） × 168 m length; 105 mm I.d. × 168 m length; 69 mm I.d. × 554 m length）. A comparison of the pneumatic conveying characteristics （PCC） pred.cted.using the seven bend.mod.ls and.experimental results shows that the pred.cted.total pipeline PCC and.trend. d.pend.on the choice of bend.mod.l. While some mod.ls pred.ct trend. that agree with the experimental results, other mod.ls pred.cted.greater bend.pressure d.ops for the d.nse phase of fly ash than for the d.lute phase.
