Background Dl-3-n-butylphthalide (NBP), first isolated from the seeds of celery, showed efficacy in animal models stroke. This study was a clinical trial to assess and safety NBP with continuous dose regimen among patients acute ischemic Methods A randomized, double-blind, double-dummy enrolled 573 within 48 hours onset stroke China. Patients were randomly assigned receive 14-day infusion followed by an capsule, 14- day aspirin, or ozagrel aspirin. The measures Barthel index score modified...
In order to solve the problems of high slot leakage, low power factor and electromagnetic torque deep-slot axial flux permanent magnet machine (AFPM), a series dual (SD-AFPM) with four stators was proposed. Firstly, properties SD-AFPM, inner rotor (IR-AFPM) multi-disc (SMD-AFPM) are compared comprehensively demonstrate effectiveness proposed SD-AFPM in improving torque. Secondly, three-channel cooling system for based on structural characteristics, is designed, heat dissipation capacity...
A novel structure of the permanent magnet linear synchronous motors (PMLSMs) is proposed in this article, which oriented silicon steel sheet (OSSS) instead traditional non-oriented (NOSSS) used as mover core material. Based on characteristics longer tooth magnetic circuit PMLSMs with similar number poles and slots structure, rolling direction OSSS set to be consistent teeth, so that motor can improve permeability anti-saturation ability. The operating condition derived through thrust...
Background: The aim of this study was to compare the surgical outcomes endoscopic thyroidectomy (ET) and conventional open (COT) for benign thyroid nodules. Methods: Between March 2001 November 2014, 224 patients underwent ET via breast approach 218 COT. Clinicopathological characteristics were retrospectively compared. Results: operation time significantly longer in group than COT (P = 0.000). However, had less intraoperative blood loss 0.000), amount drainage shorter duration cosmetic...
The feasibility and safety of endoscopic thyroidectomy were evaluated by an approach systematic review published studies in the past decade.A database searching was performed on MEDLINE, Cochrane Database Systematic Reviews, American College Physicians Journal Club, Abstracts Reviews Effects, Central Register Controlled Trials. Both comparative non-comparative about selected analyzed. For studies, RevMan 4.2 used for statistical analysis; data analysis SPSS 13.0.Seven involving 367 patients...
To study whether the yokeless and segmented armature axial-flux interior permanent-magnet (YASA-AF-IPM) has more advantages in electromagnetic performance than traditional (YASA-AFPM) when applied to electric vehicles, structure characteristics of two kinds motors with different topologies were analyzed, YASA-AF-IPM YASA-AFPM motor designed respectively by finite element method. The operation is compared analyzed aspects no-load back electromotive force, rated torque, torque ripple, eddy...
Laparoscopic hepatectomy has been widely performed for patients with benign liver tumors such as hepatic hemangioma, focal nodular hyperplasia, and adenoma. We here present a case of 78-year-old female patient who was initially admitted to our department due fever jaundice 2 days. Abdominal enhanced computed tomography scan showed intrahepatic extrahepatic bile duct dilatation atrophy left lobe. Unenhanced nodules were seen within the duct. Ultrasonography revealed viscous fluid, tubular...
The authors report a power-dividing-based microwave power thin film resistor (MPTFR) that exhibits high operating frequency and load. MPTFR is comprised of substrate, ground electrodes, two TaN resistive films, dividing circuit signal input port. experimental results show the voltage standing wave ratio lower than 1.6 in band 3.4–7.4 GHz 8.2–9.8 GHz. load 200 W. data are good agreement with electromagnetic simulations.
The aim of this study was to assess the safety and efficacy endoscopic thyroidectomy (ET) for bilateral thyroid diseases.From March 2001 January 2011, we performed a retrospective review 30 cases ET via breast approach diseases. We rendered 50 unilateral (group 2) another open diseases 3) as control groups. Comparison between groups 1 2 3 in perioperative details follow-up reviewed.The patients group required longer operating time, more intraoperative blood loss, amount drainage,...
Linear feed system of high precision and speed CNC machine tool is direct driven by Permanent magnet linear synchronous motor (PMLSM). In order to reduce transient vibration caused PMLSM in start stop with change, the jerk motion profile was designed using sinusoidal curve without any abrupt corner. An objective function minimized which composed execution time integral squared jerk. The kinematic physical limitations PMSLM were considered optimal proceeding. Compared other planning,...
Background/Aim. Surgery for developmental dysplasia of the hip (DDH) often needs acetabuloplasty and femoral osteotomy. This type operation is characterized by long duration, major trauma, severe postoperative pain. The aim study was to compare analgesic effects caudal block (CB) epidural (EB) on DDH surgery in children. Methods. A total 100 children undergoing our hospital from May 2018 December 2021 were selected randomly divided into two groups: an ultrasound-guided CB group EB (each...
The slot shape of yokeless and segmented armature (YASA) motor differs significantly from the traditional ones due to its dual openings. This paper proposes an analytical method for determining leakage inductance novel YASA axial flux permanent magnet (AFPM) motor. A general formula calculating component within a single is derived phase YASA-AFPM further yielded based on unique winding distribution. It reveals that coil-side width has significant influence while pole-slot combination...
