background: lactoperoxidase (lpo) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. the aim of this study was to provide information on activity and thermal inactivation behavior of lpo in iranian cow and buffalo milk and whey. methods: sixty cow and buffalo milk samples were collected. the lpo activity was measured using spe...

This paper reports on the detection of nano-scale chemical variations in photosensitive polymers using scanning thermal probes fabricated from polyimide and metal thin films on a silicon substrate. The high thermal insulation achieved by these probes permits the measurement of thermal conductance variations <10 W/K. The probes are mechanically very compliant, with a typical a measured spring co...

Many existing works in face recognition are based solely on visible images. The use of bimodal systems based on visible and thermal images is seldom reported in face recognition, despite its advantage of combining the discriminative power of both modalities, under expressions or pose variations. In this paper, we investigate the combined advantages of thermal and visible face recognition on a P...

The effect of microstructural variations on the fracture toughness of Alloy 718 was reviewed. The metallurgical parameters surveyed in this paper included heat treatment, heat-to-heat variations, product-form variations, neutron irradiation and long-term thermal aging. Key microstructural features and operative fracture mechanisms were related to macroscopic fracture toughness properties.

Surface temperature anomalies associated with geothermal activity at Bradys Hot Springs, Churchill County, Nevada were mapped using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) thermal infrared (TIR) image data. In order to highlight subsurface contributions of geothermal heat, the ASTER images were processed to minimize temperature variations caused by the diurnal hea...

Introduction: Interior heat flow provides essential constraints on the thermal and chemical evolution of planetary bodies. On the moon, heat flow instrument designs typically have to reach depths below the annual solar thermal wave for the Moon (2-3 m), or alternatively methods must be applied to be able to decouple the influence of the relatively large temperature gradients associated with the...

We propose a system for measuring entropy 1 variations, S, in thermal systems using pyroelectric sensors. 2 These sensors convert time-dependent temperature variations 3 into electrical current. Consequently, heat and temperature 4 variations are obtained, and sensor entropy is inferred. Various 5 polyvinylidene fluoride and lead zirconate titanate sensors have 6 been tested. Two types of measu...

paper undertakes software based numerical simulations in two different traditional houses in cold-dry climate of tabriz and hot-arid climate of yazd, the eco test software chosen for bim simulations. case study on real houses instead of hypothetical models can give more tangible results and choosing traditional houses can provide a good opportunity to compare both physical and thermal condition...

Although several studies have compared thermal sensitivity between body segments, little is known on regional variations within body segments. Furthermore, the effects of exercise on the thermal sensation resulting from a cold stimulus remain unclear. The current experiment therefore aimed to explore interand intra-segmental differences in thermal sensitivity to cold, at rest and during light e...
