key words: Parchment ageing, shrinkage temperature, thermal diffusivity, thermography The structure of the parchment and its preservation state have been studied by means of novel methods based on the analysis of the heat diffusion and the shrinkage activity. Investigations have been performed on modern, inked and non-inked, parchment artificially aged in different conditions, as well as on mod...

Perfusion dynamics of 16 free DIEP flaps and 4 free SIEA flaps were studied during the first, third, and sixth postoperative day using dynamic infrared thermography (DIRT). For both flap types the zone positioned over the perforator is perfused first, followed by the adjacent ipsilateral zone, and finally the contralateral zones. Perfusion of the subdermal plexus of all zones preceded the perfu...

Preservationists look to methods of nondestructive evaluation (NDE) to answer questions about the condition, strength, and construction details of wood in historic buildings in the interest of saving historic fabric and reducing or eliminating damage to significant historic features or materials caused by investigative probes. Many times, a basic wood inspection can answer questions posed when ...

We investigated various essential factors for optimum infrared thermography for cattle clinics. The effect of various factors on the detection of surface temperature was investigated in an experimental room with a fixed ambient temperature using a square positioned on a wall. Various factors of animal objects were examined using cattle to determine the relationships among presence of hair, body...

Varicocele is frequent but correctable cause of male infertility. Varicocelectomy is the most commonly performed operative procedure for varicocele. Majority of varicocele patients do not have fertility problem, therefore surgical correction is not recommended in all prevalent cases. On the other hand, varicocele is a progressive condition in some cases and individual with varicocele is at risk...

Abstract The paper emphasizes an effective quantification of hidden damage in composite structures using ultrasonic guided wave (GW) propagation-based structural health monitoring (SHM) and artificial neural network (ANN) based active infrared thermography (IRT) analysis. In recent years, there has been increased interest a global-local approach for localization purposes. global is mainly used ...

In order to better understand the thermomechanical behavior of the skin and its direct environment, we present an experimental study using infrared thermography. This experimental study aims to highlight quantitatively some effects of blood flow on the heat diffusion. The originality of this research is to change the blood flow by using effects of gravity and to quantify the temperature changes...

A three-dimensional unsteady inverse model has been developed in order to compute heat fluxes and surface temperature in various configurations. Temperature measurements are taken backside using infrared thermography. The number of unknown parameters is reduced using a discrete cosine transform analysis and by canceling values lower than a prescribed level. The efficiency of the method is prove...

Infrared thermography was used to measure heat transfer by radiation and the surface temperature of starlings (Sturnus vulgaris) (N=4) flying in a wind tunnel at 6-14 m s-1 and at 15-25 degrees C. Heat transfer by forced convection was calculated from bird surface temperature and biophysical modelling of convective heat transfer coefficients. The legs, head and ventral brachial areas (under the...
