Temperature measurements using planar laser-induced fluorescence (PLIF) are most often associated with experimental challenges. In addition, no PLIF technique is generally applicable in all kinds of environment. Especially under sooting conditions problems are prone to arise, which limits the use of these techniques. In this paper the two-line atomic fluorescence (TLAF) technique was investigat...

Minimally invasive spine surgeries (MISS) are becoming increasingly favored as alternatives to open spine procedures because of the reduced blood loss, postoperative pain, and recovery time. Studies have shown mixed results regarding the efficacy and safety of minimally invasive procedures compared to the traditional, open counterparts. The objectives of this systematic analysis are to compare ...

BACKGROUND: The safety and efficacy of transforaminal lumbar interbody fusion (TLIF) posterior (PLIF) in spondylolisthesis have not been validated many prospective randomized trials. AIM: We aimed to validate the TLIF PLIF surgery using clinical, radiographic, cost-utility outcomes. METHODS: data surgically treated single-level patients were prospectively into two groups. groups compared regard...

Abstract Background In several previous studies, Charlson comorbidity index (CCI) score was associated with postoperative complications, mortality, and re-admission. There are few reports about the influence of CCI on clinical outcome. The purpose this study to investigate comorbidities as calculated outcomes after PLIF. Methods Three hundred sixty-six patients who underwent an elective primary...

Internal waves are ubiquitous in the ocean. They often form regions of high temperature or salinity variability as pycnocline oscillates to wave (Phillips, 1966). can be generated either from interaction tidal currents with submarine bathymetry (Garrett and Kunze, 2007) by wind stress at ocean surface (Munk Wunsch, 1998). The current study addresses non-linear internal due their importance mixi...

This paper presents advanced image analysis methods for extracting information from high speed Planar Laser Induced Fluorescence (PLIF) data obtained from turbulent flames. The application of non-linear anisotropic diffusion filtering and of Active Contour Models (Snakes) is described to isolate flame boundaries. In a subsequent step, the detected flame boundaries are tracked in time using a fr...
