| 1 | Application of entransy dissipation based thermal resistance to design optimization of a novel finless evaporator显示文摘Entransy has been applied and studied in a broad range of heat transfer optimizations recently. Current study proposes the entransy of evaporators to conduct the optimization of heat exchangers in heating, ventilation, air conditioning and refrigeration systems. A novel finless bare tube heat exchanger was studied using a validated heat exchanger modeling tool. The capacity based optimization and entransy dissipation based thermal resistance were used and compared. The applicability of using entransy dissipation based thermal resistance in this type of heat exchanger optimization has been discussed. It has been demonstrated that minimizing entransy dissipation and maximizing capacity are equivalent to optimizing evaporators with fixed flow rates and different when optimizing evaporators with variable flow rates and the deviation is negligible when heat exchanger capacity is small(~1 k W) and more obvious as heat exchanger capacity increases. Thus entransy dissipation based thermal resistance could be used as an alternative optimization index to capacity for evaporators with fixed flow rate and small capacity evaporators with variable flow rates and should be used individually with capacity as an optimization index for evaporators with large capacity and variable flow rates. | HUANG ZhiWei LI ZhenNing HWANG Yunho RADERMACHER Reinhard | 2016 | Science China(Technological Sciences)2016，59，10： | 6 |
| 2 | Colour stabilities of three types of orthodontic clear aligners exposed to staining agents显示文摘The aim of this study was to evaluate and compare the colour stabilities of three types of orthodontic clear aligners exposed to staining agents in vitro. Sixty clear orthodontic aligners produced by three manufacturers(Invisalign, Angelalign, and Smartee)were immersed in three staining solutions(coffee, black tea, and red wine) and one control solution(distilled water). After 12-h and 7-day immersions, the aligners were washed in an ultrasonic cleaner and measured with a colourimeter. The colour changes(ΔE*) were calculated on the basis of the Commission Internationale de I'Eclairage L*a*b* colour system(CIE L*a*b*), and the results were then converted into National Bureau of Standards(NBS) units. Fourier transformation infrared(FT-IR) spectroscopy and scanning electron microscopy(SEM) were conducted to observe the molecular and morphologic alterations to the aligner surfaces, respectively. The three types of aligners exhibited slight colour changes after 12 h of staining, with the exception of the Invisalign aligners stained with coffee. The Invisalign aligners exhibited significantly higher ΔE* values(ranging from 0.30 to27.81) than those of the Angelalign and Smartee aligners(ΔE* values ranging from 0.33 to 1.89 and 0.32 to 1.61, respectively,Po0.05). FT-IR analysis confirmed that the polymer-based structure of aligners did not exhibit significant chemical differences before and after the immersions. The SEM results revealed different surface alterations to the three types of aligner materials after the 7-day staining. The three types of aesthetic orthodontic appliances exhibited colour stability after the 12-h immersion, with the exception of the Invisalign aligners stained by coffee. The Invisalign aligners were more prone than the Angelalign and Smartee aligners to pigmentation. Aligner materials may be improved by considering aesthetic colour stability properties. | Chen-Lu Liu Wen-Tian Sun Wen Liao Wen-Xin Lu Qi-Wen Li Yunho Jeong Jun Liu Zhi-He Zhao | 2016 | International Journal of Oral Science2016，8，4： | 5 |
| 3 | Rescue endoscopic band ligation of iatrogenic gastric perforations following failed endoclip closure显示文摘Iatrogenic gastric perforation is one of the most serious complications during therapeutic endoscopy,despite significant advances in endoscopic techniques and devices.This case study evaluated the clinical efficacy and safety of the rescue endoscopic band ligation (EBL) technique in iatrogenic gastric wall perforation following the failure of primary endoclip closure.Five patients were enrolled in this study.These patients underwent emergency endoscopy following the onset of acute gastric wall perforation during endoscopic procedures.The outcome measurements were primary technical success and immediate or delayed procedure-related complications.Successful endoscopic closure using band ligation was reported in all patients,with no complication occurring.We conclude that EBL may be a feasible and safe alternate technique for the management of acute gastric perforation,especially in cases where closure is difficult with endoclips. | Joung-Ho Han Tae Hoon Lee Yunho Jung Suck-Ho Lee Hyun Kim Hye-Suk Han Heebok Chae Seon Mee Park Seijin Youn | 2013 | World Journal of Gastroenterology2013，19，6： | 5 |
| 4 | Effectiveness of circumferential endoscopic mucosal resection with a novel tissue-anchoring device显示文摘AIM: To evaluate the efficacy of circumferential endoscopic mucosal resection (EMR) with a tissue-anchoring device in comparison to forceps precut EMR and conventional endoscopic submucosal dissection (ESD). METHODS: The study was designed as a prospective, randomized, ex vivo study. Fresh ex vivo specimens were harvested from adult white Yorkshire pigs weighing 30-50 kg. Seventy-five standardized, artificial lesions measuring 3 cm × 3 cm were created by methy- lene blue tattoo at the greater curvature in fresh ex vivo stomachs using the EASIE-R simulator platform (Endosim LLC, Berlin, MA, United States). The three advanced endoscopists performed the three resection techniques such as circumferential EMR using the tissue-anchoring device (TA-EMR), forceps precut EMR (FP-EMR), and endoscopic submucosal dissection. The endoscopists and the type of cutting methods were determined randomly by grouped randomized selection.The resection bed was grossly inspected to determine whether the lesion was resected 'en-bloc ' (defined as no remaining mucosal tattoo remaining on specimen). The resection bed was also probed for evidence of perforation. The procedural time of circumferential resection, submucosal dissection, and injection frequency were recorded by an independent observer.RESULTS: All 75 created lesions were successfully resected by three advanced endoscopists using the three techniques. The mean ± SD size of resected specimens (long axis) were 39.5 ± 5.6 mm, 36.5 ± 7.3 mm, and 44.6 ± 5.6 mm for TA-EMR, FP-EMR, and ESD respectively. The overall mean dissection time of both the TA- EMR and FP-EMR was significant shorter than ESD (TA- EMR: 5.1 ± 3.3 min, FP-EMR: 3.5 ± 2.0 min vs ESD: 15.8 ± 9.5 min, P < 0.001, P < 0.001). The overall mean total procedure time of both the tissue-anchoring and forceps circumferential EMR was significantly shorter than ESD (TA-EMR: 17.5 ± 6.0 min, FP-EMR: 16.6 ± 6.6 min vs ESD: 28.6 ± 13.9 min, P < 0.001, P < 0.001). The en-bloc resection rate of ESD was 100% (25/25) and the en-bloc resection rate of the TA-EMR (84.0%, 21/25) was higher than for the FP-EMR (60.0%, 15/25), yet not statistically significant (P = 0.18). The perforation rate of each technique was 8.0% (2/25). CONCLUSION: TA-EMR appears to be quicker than ESD, and there was a trend towards improved en bloc resection rate with the TA-EMR when compared to the FP-EMR. | Yunho Jung Masayuki Kato Jongchan Lee Mark A Gromski Ram Chuttani Kai Matthes | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，6： | 3 |
