Contribution to contact temperature measurement

An automated non-contact wall temperature measurement using thermoreflectance

This work presents a novel implementation of wall temperature measurement by thermoreflectance. The implementation relies on imaging light reflected from an interface between a transparent wall and liquid, and processing the resulting digital images to measure the diameter of the resulting light ring. The system is relatively simple to implement and the validation data indicate that the output ...

High-dynamic Infrared Cameras for Non-contact Temperature Measurement from 300 °C to 3000 °C

State of the art IR cameras in the near infrared spectral range for monitoring high temperatures in industrial applications are characterized by a number of small measurement ranges. Scenes with a high temperature contrast require several measures switching between these ranges and result in pictures with underrespectively overexposed parts. New developed high temperature IR cameras with high-d...

Contribution of 3-hydroxyisobutyrate to the measurement

In this study we employed a capillary gas-liquid chromatographic-mass spectrometric (GLC-MS) method to measure the plasma concentrations of 3-hydroxybutyrate (3OHB) and 3-hydroxyisobutyrate (3-OHIB) in overnight fasted diabetic subjects and in normal subjects. Plasma contents of 3-hydroxybutyrate measured in this fashion were identical to those obtained by enzymatic assay using a commercial pre...

Contribution of Langerhans cell-derived IL-18 to contact hypersensitivity.

The epidermal Langerhans cells (LC), a member of the dendritic cell family, and the LC-derived cytokine IL-12 play a pivotal role in the initiation of contact hypersensitivity (CHS), a Th1 immune response in the skin. Because IL-18, another LC-derived cytokine, shares functional and biological properties with IL-12, we examined a potential role for IL-18 in CHS initiation. Our studies demonstra...
