Vespine wasps are known for their high endothermic capacity. Endothermic activity is directly linked to respiration. However, knowledge on wasp respiration is sparse and almost nothing is known about their resting metabolism. We investigated the yellowjackets' CO(2) production in a flow-through respirometer chamber overnight. Endothermic and behavioral activity was observed by real-time infrare...

Abstract Human being cannot maintain her life in the earth without air and water. Especially, the nature of water has not been evident even now from scientific viewpoint. It has been reported that it is strongly influenced by the shape of cluster of water molecule, which depends upon water’s surroundings such as light, sound, magnet, heat, etc. This study clarifies the behaviors on fluctuating ...

This paper reviews the most dependable heat flux sensors, which can be used with InfraRed (IR) thermography to measure convective heat transfer coefficient distributions, and some of their applications performed by the authors' research group at the University of Naples Federico II. After recalling the basic principles that make IR thermography work, the various heat flux sensors to be used wit...

Obstructions in the lacrimal pathways quite often require accurate and reliable image scanning for confirmation and documentation. Infrared thermal imaging, known as thermography, is a resource that complements diagnosis; it does not require touching the patient or applying contrast materials and has been used in various medical procedures for decades. However, there have been few studies in th...

In recent years, a technique known as thermography has been again seriously considered as a complementary tool for the pre-diagnosis of breast cancer. In this paper, we explore the predictive value of thermographic atributes, from a database containing 98 cases of patients with suspicion of having breast cancer, using Bayesian networks. Each patient has corresponding results for different diagn...

BACKGROUND During middle ear surgery manipulations like burring, cooling with water, suction or even screwing cause changes of temperature which should be known to the surgeon. METHOD An infrared thermovision device was introduced for registration. RESULTS Thermography is an easy way for continuously recording thermic effects during surgery. If sufficient cooling is guaranteed, no temperatu...

Thermographic signal reconstruction (TSR) and partial least squares thermography (PLST) are techniques conceived for the processing and analysis of pulsed thermography (PT) data. In this work, the capabilities of both techniques are evaluated. A thermal data sequence was obtained from a PT inspection on a carbon fiber reinforced polymer (CFRP) specimen with simulated delaminations (Teflon inser...

The aim of this paper is to present the advantages of using Digital Image Correlation (DIC) and Infrared Thermography (IRT) to investigate the thermomechanical behavior of aluminum at the scale of its microstructure. The study combines these complementary imaging techniques: Electron Backscatter Diffraction (EBSD) to characterise the microstructure of the sample, DIC to obtain strain fields and...

In this area, there was a large group of well women aged over 35 years eager for breast screening. For this survey using clinical examination, thermography, and mammography, we selected women considered to be at higher than average risk of breast cancer. Initially, unselected women were seen, by appointment, for clinical examination and thermography (see pp. 1664-1670, this issue). From that gr...

In this case study of a unique instance, the effects of non-invasive generated shockwaves onto the skin and the underlying fat tissue of a cellulite-afflicted, 52-year-old woman were investigated. The treatment was applied at the lateral thighs once per week for a period of 10 weeks. Diagnostic high-resolution ultrasound (Esaote 25 Gold® device with 15–18 MHz linear probe), thermography (Thermo...
