“…These differences in results may be based on a number of influencing factors such as the data collection time, room temperature (Ammer & Ring, 2008), type of camera used (Nguyen et al, 2010) and race of the subject (Zhu and Xin, 1999). For a better comparison of data in future studies, it is important to indicate the criteria and conditions for data collection and to identify the cameras used.…”

Thermal body patterns for healthy Brazilian adults (male and female), Journal of Thermal Biology, http://dx.doi.org/10. 1016/j.jtherbio.2014.02.020 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. A B S T R A C TThe aim of this study was to establish the skin temperature (T sk ) thermal profile for the Brazilian population and to compare the differences between female and male Brazilian adults. A total of 117 female and 103 male were examined with a thermographic camera. The T sk of 24 body regions of interest (ROI) were recorded and analyzed. Male T sk results were compared to female and 10 ROI were evaluated with respect to the opposite side of the body (right vs. left) to identify the existence of significant contralateral T sk differences (ΔT sk ). When compared right to left, the largest contralateral ΔT sk was 0.3 °C. The female vs. male analysis yielded significant differences (p <0.05) in 13 of the 24 ROI. Thigh regions, both ventral and dorsal, had the highest ΔT sk by sex (≈ 1.0 °C). T sk percentile below P 5 or P 10 and over P 9o or P 95 may be used to characterize hypothermia and hyperthermia states, respectively. Thermal patterns and T sk tables 2 were established for Brazilian adult men and women for each ROI. There is a low T sk variation between sides of the body and gender differences were only significant for some ROIs. Keywords: Infrared thermographySkin temperature Thermal symmetry Brazilian profile HighlightsEstablishing a standard thermographic profile is crucial for an appropriate interpretation.Standardization of the protocols leads to obtain comparable results.Gender seems to be a determining factor for the skin temperature of the thigh, calf and dorsal arm.We suggest the value of 0.5 °C as a normal limit for contralateral ΔT sk.

Purpose: To evaluate infrared thermometer (IRT) accuracy compared to standard digital thermometer in measuring kidney temperature during arterial clamping with and without renal cooling. Materials and Methods: 20 pigs weighting 20Kg underwent selective right renal arterial clamping, 10 with (Group 1 -Cold Ischemia with ice slush) and 10 without renal cooling (Group 2 -Warm Ischemia). Arterial clamping was performed without venous clamping. Renal temperature was serially measured following clamping of the main renal artery with the IRT and a digital contact thermometer (DT): immediate after clamping (T0), after 2 (T2), 5 (T5) and 10 minutes (T10). Temperature values were expressed in mean, standard deviation and range for each thermometer. We used the T student test to compare means and considered p < 0.05 to be statistically significant. Results: In Group 1, mean DT surface temperature decrease was 12.6 ± 4.1ºC (5-19ºC) while deep DT temperature decrease was 15.8 ± 1.5ºC (15-18ºC). For the IRT, mean temperature decrease was 9.1 ± 3.8ºC (3-14ºC). There was no statistically significant difference between thermometers. In Group 2, surface temperature decrease for DT was 2.7 ± 1.8ºC (0-4ºC) and mean deep temperature decrease was 0.5 ± 1.0ºC (0-3ºC). For IRT, mean temperature decrease was 3.1 ± 1.9ºC (0-6ºC). No statistically significant difference between thermometers was found at any time point. Conclusions: IRT proved to be an accurate non-invasive precise device for renal temperature monitoring during kidney surgery. External ice slush cooling confirmed to be fast and effective at cooling the pig model.

Abstract. The intensity of infrared radiation emitted by objects depends mainly on their temperature. One of the diagnostic signals may be the temperature field. In infrared thermography, this quantity is used as an indicator of the technical condition of marine objects. The article presents an overview of the use of infrared thermography for the diagnosis mainly of marine piston floating objects and various types of reciprocating internal combustion engines as well as examples of own research results. A general introduction to infrared thermography and common procedures for temperature measurement and non-destructive testing are presented. Experimental research was carried out both in laboratory conditions and in the operating conditions of sea-going vessels. Experimental studies consisted of the presentation of photographs of the same objects made in visible light and the use of infrared thermography. The same objects were also compared, but for different cylinders of the tested internal combustion engines as well as for the up state and fault state. The characteristics of the temperature values at selected points were taken depending on the engine load along with the approximation mathematical models of these dependencies.
