BACKGROUND We retrospectively evaluated the clinical and radiological outcomes of posterior lumbar interbody fusion (PLIF) with using a unilateral single cage and a local morselized bone graft. METHODS Fifty three patients who underwent PLIF with a unilateral single cage filled with local morselized bone graft were enrolled in this study. The average follow-up duration was 31.1 months. The cl...

1 . I N T R O D U C T I O N Microrobotics researches require to operate on autonomous devices with simple design and limited costs and energy consumption, even if this fact limits the possible tasks of each single robot. In the last few years the interest in micro mechatronic systems is increasing and several different kind of microrobots have been designed [1], [2],[3]. Applications of these r...

In view of the uncertainty in calibration process two-color plane laser-induced fluorescence (PLIF) temperature measurement, a new method is proposed, which influence yield considered. The was carried out at high and low region, respectively. Then, bias thermometry results origin from quenching restrained. This validated jet flame with range 1300–1800 K. Here, Coherent Anti-Stokes Raman scatter...

This experimental study describes the effect of oscillating grid on hydrodynamics and mass transfer in an aquarium. The contribution two driving elements CO2 is identified. Depending operating conditions, either these effects add up promote circulation transport liquid, or are opposite, liquid velocity then reduced. On other hand, with regard to gas-liquid transfer, use beneficial since, under ...

目的：观察改良后路腰椎体间融合术（PLIF）治疗腰椎管狭窄症的临床疗效。方法：选取2019年6月-2020年6月我院收治的62例腰椎管狭窄症患者为研究对象，按照是否行改良PLIF治疗将患者分为对照组（31例：行传统PLIF治疗）与实验组（31例：行改良PLIF治疗），比较两组患者治疗效果。结果：实验组患者术后3个月总有效率（96.77%）显著高于对照组，数据差异明显（P<0.05）。实验组患者术后半年视觉模拟VAS评分以及Oswestry生活功能障碍指数（ODI）均优于对照组，数据差异明显（P<0.05）。结论：腰椎管狭窄症患者改良PLIF治疗效果明显优于传统PLIF治疗效果。

Abs ract : In the present paper, the development of a high-resolution PIV-PLIF combined system for the simultaneous measurements of velocity and passive scalar concentration fields is described. The high-resolution PIV-PLIF combined system is used to perform the simultaneous whole-field measurements of velocity and concentration in the near field of a turbulent jet mixing flow. The characterist...

The mixing behavior around a SMX-type static mixer segment has been investigated experimentally by using Particle Image Velocimetry (PIV) and Planar Laser-Induced Fluorescence (PLIF) simultaneously. To quantify mixing, velocity fields and concentration fields have been measured for different Reynolds numbers along vertical and horizontal sections directly behind the mixer. The experimental data...

OBJECTIVE The aim of this study was to compare the curative effect between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and the posterior lumbar interbody fusion (PLIF) in obese patients with lumbar disk prolapse. PATIENTS AND METHODS In this study, 72 patients who underwent lumbar disk prolapse therapy in the Third Hospital of Hebei Medical University between March 20...

The aim of this study was to directly compare the clinical outcomes of posterior lumbar interbody fusion (PLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in three-level lumbar spinal stenosis. This retrospective study involved a total of 60 patients with three-level degenerative lumbar spinal stenosis who underwent MIS-TLIF or PLIF from January 2010 to February 20...

High speed planar laser induced fluorescence (PLIF) imaging of the OH radical is presented in a turbulent nonpremixed methane-air flame. Sequences of up to eight successive PLIF images could be resolved sequentially at several kHz repetition rates. Turbulent flow phenomena such as vortex formation and air entrainment in the flow could be visualised and their development tracked in real time. Tu...
