Summary: Background: Assessment of cardiac electromechanical function in horses requires training, experience and specialised equipment and does not allow continuous monitoring over time. Objectives: The objective of this study was to establish the use of an acoustic ECG monitor (Audicor®) in healthy horses. It provides noninvasive, examiner‐independent, continuous analyses combining ECG and phonocardiography to calculate indices of cardiac mechanical activity and haemodynamics. Device usability was investigated, reference intervals calculated and reproducibility of analyses assessed. Study design: Prospective descriptive study. Methods: Continuous overnight recordings were obtained in 123 healthy horses. ECG and acoustic cardiography analyses were performed. Electromechanical activating time (EMAT), rate‐corrected EMATc, left ventricular systolic time (LVST), rate‐corrected LVSTc and intensity and persistence of the third and fourth heart sound (S3, S4) were reported. Associations with age and reproducibility of analyses were assessed. Results: Audicor® recordings of diagnostic quality were obtained in 116 horses, with an artefact‐free recording time of 1:08–14:03 h (mean 10:21 h). 44.8% of the horses had atrial premature complexes (up to 0.18% of analysed beats), 4.3% had ventricular premature complexes (up to 0.021% of analysed beats). Reference intervals for acoustic cardiography variables were reported. S3 was significantly more often graded ≥5 (scale 0–10) in younger compared to older horses (P = 0.0036, R2 = 0.072). The between‐day coefficient of variation ranged from 2.5 to 7.7% for EMAT, EMATc, LVST and LVSTc. Main limitations: Audicor® algorithms are based on human databases. Horses were deemed clinically healthy without advanced diagnostics. Some data were lost because of technical difficulties, artefacts and noises. Conclusions: Overnight Audicor® recordings are feasible in horses. Combining ambulatory ECG and phonocardiography allows noninvasive, continuous assessment of variables representing systolic and diastolic cardiac function. ECG rhythm analyses require over‐reading by a specialist, but acoustic cardiography variables are based on automated algorithms independent of examiner input. Further studies are required to establish the clinical value of acoustic cardiography in horses. [ABSTRACT FROM AUTHOR]

The burn injury hazard of fabrics has been conceptually related to laboratory test methods. The relation is to be de rived from the description of the relevant processes which lead to burn injury. Among these processes stand out the ig nition, the burn and the tissue denaturalization processes as predominately deterministic because of predictable fabric response.Presented here are the results of an experimental and analytical investigation into the fabric ignition process. Thermo physical fabric properties relevant to the description of the ignition process have been presented. Fabric ignition times were measured under radiative heating. Modeling rules for the ignition process are presented. [ABSTRACT FROM PUBLISHER]
