Study on Dust Particle Deposition Movement in Pipe of FF System
Fan bailin,Huang ganghan,Wang Hongwei,Shan Quanfeng 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.2
The Particle deposition position and subside curve equation was studied. Particle depositing Para-curve formula was generated through the dust particle dynamic analysis in the pipe. Settlement nephogram and the trajectory curve of dust particle were obtained by FLUENT numerical simulation. Depositing velocity of particle was simulated and the simulation results, the calculated results and the experimental result were compared and analyzed. The particle motion was reflected by coordinate equation and parabolic curves were drawn for the particle No.65 in the z direction. Various depositing velocities in horizontal rectangle pipe under different particle diameter and flow velocity circumstances were compared to summarize motion patterns.

Purpose: The current meta-analysis combining mid and low rectal cancer with no meta-analysis only for low rectal cancer was seen. This meta-analysis was to compare the short- and mid-term outcomes of the transanal total mesorectal excision (TaTME) vs. laparoscopic total mesorectal excision (LaTME) for low rectal cancer. Methods: A systematic literature search was conducted using the web-based databases; China National Knowledge Infrastructure, Chinese BioMedical Database, PubMed, Embase, Cochrane Central Register of Controlled Trials, and Wanfang Database. Randomized controlled trials (RCTs) were evaluated using the Jadad scale and non-RCTs (NRCs) were evaluated using the Newcastle-Ottawa Scale. Results: Ten studies (2 RCTs and 8 NRCs) involving 772 patients were included. Among them, 378 patients underwent TaTME and 394 patients underwent LaTME. Compared with the LaTME group, the conversion rate was low (risk ratio [RR], 0.25; 95% confidence interval [CI], 0.11–0.54; P < 0.001), the circumferential resection margin (CRM) involvement was low (RR, 0.48; 95% CI, 0.27–0.86; P = 0.010), and the hospital stay was short (mean difference, –1.72; 95% CI, –2.89 to –0.55; P = 0.004) in the TaTME group. No significant differences were seen in the mesorectal resection quality, CRM distance, distal resection margin (DRM) involvement, DRM distance, local R1 resection, intraoperative complications, morbidity, anastomotic leakage, severe morbidity, mortality, operative time, intraoperative blood loss, harvested lymph nodes, and local recurrence rate (P > 0.05). Conclusion: The TaTME is a promising surgical technique and is fully a safe and efficacious option in managing low rectal cancer.
