Laser fluence, repetition rate and pulse duration effects on paint ablation
2006
Abstract The efficiency (mm3/(J pulse)) of laser ablation of paint was investigated with nanosecond pulsed Nd:YAG lasers (λ = 532 nm) as a function of the following laser beam parameters: pulse repetition rate (1–10,000 Hz), laser fluence (0.1–5 J/cm2) and pulse duration (5 ns and 100 ns). In our study, the best ablation efficiency (η ≅ 0.3 mm3/J) was obtained with the highest repetition rate (10 kHz) at the fluence F = 1.5 J/cm2. This ablation efficiency can be associated with heat accumulation at high repetition rate, which leads to the ablation threshold decrease. Despite the low thermal diffusivity and the low optical absorption of the paint (thermal confinement regime), the ablation th…

Äskettäin diagnosoitujen Parkinsonin tautia sairastavien potilaiden kävely ja tasapaino : itsekoetun ja mitatun pystyasennon hallinnan ja kävelyn suo…
2013
Tämän tutkimuksen tarkoituksena oli selvittää äskettäin diagnosoidun Parkinson-potilaan itsearvioimaa pystyasennon hallintaa ja kävelyä suhteessa valittuihin kliinisten mittausten muuttujiin. Tutkimuksessa käytetyt mittarit olivat Bergin tasapainotesti (BBS), Timed Up and Go-testi (TUG), Four Square Stepping Test (FSST), GoodBalance ja GaitRite. Tutkittaville suoritettiin myös strukturoitu kysely tasapaino- ja kävelyrajoituksista. Tutkimus oli poikkileikkaustutkimus, jonka aineisto kerättiin Satakunnan sairaanhoitopiirin alueella vapaaehtoisista, vuoden 2007 kuluessa diagnosoitujen uusien potilaiden joukosta.

Clinical Potential of Circulating Cell-Free DNA (cfDNA) for Longitudinally Monitoring Clinical Outcomes in the First-Line Setting of Non-Small-Cell L…
2022
Background: Despite the increasing implementation of targeted and immunotherapy-based treatments, the prognosis of patients with advanced NSCLC remains dismal. We prospectively evaluated longitudinal plasma cfDNA kinetics as an early marker of therapeutic efficacy in patients with advanced NSCLC undergoing standard first-line treatments. Methods: From February 2020 to May 2022, treatment-naïve patients with advanced NSCLC were consecutively enrolled at the Medical Oncology Unit of the Paolo Giaccone University Hospital, Palermo (Italy). We quantified cfDNA in terms of ng/μL using a QubitTM dsDNA HS Assay Kit. The agreement between the cfDNA and radiologic response was evaluated from…
Parametric sensitivity of a CFD model concerning the hydrodynamics of trickle-bed reactor (TBR)
2016
Abstract The aim of the present study was to investigate the sensitivity of a multiphase Eulerian CFD model with respect to relations defining drag forces between phases. The mean relative error as well as standard deviation of experimental and computed values of pressure gradient and average liquid holdup were used as validation criteria of the model. Comparative basis for simulations was our own data-base obtained in experiments carried out in a TBR operating at a co-current downward gas and liquid flow. Estimated errors showed that the classical equations of Attou et al. (1999) defining the friction factors Fjk approximate experimental values of hydrodynamic parameters with the best agre…

This work describes the deployment of the current fluid flow simulation software, Star-CCM+, at Valtra Inc. The text also gives a brief introduction to computational fluid dynamics and its role in the product development process for an engineer at the company. Two computational test cases are also described. A simpler case of the simulation of an engine air intake channel flow is shown first. The results show better agreement with the measured values than the outsourced simulation that was used as a reference. The second case is the so called underhood analysis which is a flow simulation of the whole Valtra N-series front end, including fan and heat exchangers. It is a steady state simulati…
