| 1 | Silicon carbide resonant tuning fork for microsensing applications in high-temperature and high G-shock environments显示文摘We present the fabrication and testing of a silicon carbide(SiC)balanced mass double-ended tuning fork that survives harsh environments without compromising the device strain sensitivity and resolution bandwidth.The device features a material stack that survives corrosive environments and enables high-temperature operation.To perform high-temperature testing,a specialized setup was constructed that allows the tuning fork to be characterized using traditional silicon electronics.The tuning fork has been operated at 600 ℃ in the presence of dry steam for short durations.This tuning fork has also been tested to 64 000 G using a hard-launch,soft-catch shock implemented with a light gas gun.However,the device still has a strain sensitivity of 66 Hz/με and strain resolution of 0.045 με in a 10 kHz bandwidth.As such,this balanced-mass double-ended tuning fork can be used to create a variety of different sensors including strain gauges,accelerometers,gyroscopes,and pressure transducers.Given the adaptable fabrication process flow,this device could be useful to micro-electro-mechanical systems(MEMS) designers creating sensors for a variety of different applications. | David R Myers Kan Bun Cheng Babak Jamshidi Robert G Azevedo Debbie G Senesky Li Chen Mehran Mehregany Muthu B J Wijesundara Albert P Pisano | 2012 | Engineering Sciences2012，10，5： | 6 |

| 19 | Laparoscopic approach in complicated diverticular disease显示文摘AIM: To analyze the results of laparoscopic colectomy in complicated diverticular disease.METHODS: This was a retrospective cohort study conducted at an academic teaching hospital. Data were collected from a database established earlier, which comprise of all patients who underwent laparoscopic colectomy for diverticular disease between 2000 and 2013. The series was divided into two groups that were compared: Patients with complicated disease(abscess, perforation, fistula, or stenosis)(G1) and patients undergoing surgery for recurrent diverticulitis(G2). Recurrent diverticulitis was defined as two or more episodes of diverticulitis regardless of patient age. Data regarding patient demographics, comorbidities, prior abdominal operations, history of acute diverticulitis, classification of acute diverticulitis at index admission and intra and postoperative variables were extracted. Univariate analysis was performed in both groups.RESULTS: Two hundred and sixty patients were included: 28%(72 patients) belonged to G1 and 72%(188 patients) to G2. The mean age was 57(27-89) years. The average number of episodes of diverticulitis before surgery was 2.1(r 0-10); 43 patients had no previous inflammatory pathology. There were significant differences between the two groups with respect to conversion rate and hospital stay(G1 18% vs G2 3.2%, P = 0.001; G1: 4.7 d vs G2 3.3 d, P < 0.001). The anastomotic dehiscence rate was 2.3%, with no statistical difference between the groups(G1 2.7% vs G2 2.1%, P = 0.5). There were no differences in demographic data(body mass index, American Society of Anesthesiology and previous abdominal surgery), operative time and intraoperative and postoperative complications between the groups. The mortality rate was 0.38%(1 patient), represented by a death secondary to septic shock in G2.CONCLUSION: The results support that the laparoscopic approach in any kind of complicated diverticular disease can be performed with low morbidity and acceptable conversion rates when compared with patients undergoing laparoscopic surgery for recurrent diverticulitis. | Nicolás A Rotholtz Alejandro G Canelas Maximiliano E Bun Mariano Laporte Emmanuel E Sadava Natalia Ferrentino Sebastián A Guckenheimer | 2016 | World Journal of Gastrointestinal Surgery2016，8，4： | 0 |
