Abstract This research deals with continuous surface body temperature measurements in cow using IR based thermometry. Body surface temperatures were estimated contactless utilizing recordings from an IR thermometry fixed at a specific region in the cow. The body surface temperatures were dissected reflectively at two regions: the rectal region (behind the tail) and abdominal region (nearer the stomach) in the cow. The traditional invasive rectal temperature filled in as a kind of perspective temperature and was estimated with a computerized thermometer at the comparing time point. An aggregate of ten cows (Redsindhi, HF cross, Kangayam ) was inspected. The normal most extreme temperatures of the territory of the rectal (mean ± SD: 38.69 ± 0.5°C) and the abdominal region (38.4 ± 0.51°C). The temperatures of these regions in the cow were 95% accurate than the traditional invasive rectal temperature measurements. Notwithstanding, the most extreme temperatures as estimated utilizing IR thermometry expanded with an expansion in cow rectal temperature. These temperature readings are then been communicate to the remote server for continuous monitoring of the condition of cows. This communication is carried out by using Bluetooth/Wifi medium. Since this framework comes out with a non-invasive fashion measuring surface body temperature, will be an alternate way of taking a reading of temperature rather than computing the internal body temperature in an invasive fashion. Subsequently, this IR thermometry shows potential as a marker for consistent temperature estimations in cows.

ABSTRACTUnderstanding the physiological processes that underpin primate performance is key if we are to assess how a primate might respond when navigating new and changing environments. Given the connection between an animal’s ability to thermoregulate and the changing demands of its thermal environment, increasing attention is being devoted to the study of thermoregulatory processes as a means to assess primate performance. Infrared thermography can be used to record the body surface temperatures of free-ranging animals. However, some uncertainty remains as to how these measurements can be used to approximate core body temperature. Here, we use data collected from wild vervet monkeys (Chlorocebus pygerythrus) to examine the relationship between infrared body surface, core body, and local climate, to determine to what extent surface temperatures reflect core body temperature. While we report a positive association between surface and core body temperature – a finding that has previously been used to justify the use of surface temperature measurements as a proxy for core temperature regulation – when we controlled for the effect of the local climate in our analyses, this relationship was no longer observed. That is, body surface temperatures were solely predicted by local climate, and not core body temperatures, suggesting that surface temperatures tell us more about the environment a primate is in, and less about the thermal status of its body core in that environment. Despite the advantages of a non-invasive means to detect and record animal temperatures, infrared thermography alone cannot be used to approximate core body temperature in wild primates.

The effects, on the body temperature of white mice, of repeated short exposures to cold were investigated using two methods of restraint. Animals held in a flattened posture became hypothermic at room temperature, cooled more than five times as fast at −10 °C as mice that could adopt a heat-conserving posture, and continued to cool for some time after they were removed from the cold. With repeated tests, cooling at room temperature decreased, and an improvement in re warming ability was observed. In addition, with lightly restrained mice, the fall in rectal temperature during cold exposure showed a progressive decrease, a phenomenon not observed with severely restrained animals.

SUMMARYObservations were made on the body temperature of a large number of diving and swimming birds of eighteen different species in the Orkney Islands and Firth of Forth, Scotland, and on and around Cayuga Lake, N.Y., U.S.A., immediately after they were killed by shooting.1. In all the species examined, where the sex was determined, it was found that the rectal temperature of the male was slightly below that of the female.2. Of the orders examined the highest temperatures were found in the Longipennes and the lowest in the Tubinares. When arranged according to body temperature the series does not run parallel with the zoological series.In conclusion, I wish to express my indebtedness to Dr H. D. Reed and Dr A. H. Wright for help in identifying the specimens obtained from Cayuga Lake and the surrounding district.

SummaryMonthly observations, extending over one year, were made on the rectal temperature of 114 domestic fowls (Gallus gallus, ♀) and records from forty-one of these were obtained for two years. Six different breeds were used, each located in a separate pen, all under similar conditions, and the mean temperatures for each group were plotted out to form an annual temperature curve. It was found that—1. The lowest temperatures occur in December, January, and February, and the highest in June, July, and August, corresponding in a general way with the temperature of the external air.2. Barometric pressure does not appear to have any influence on the body temperature of the hen.3. The curve of egg-production does not coincide with the annual temperature curve, the former reaching its highest level in April and May, the latter in June, July, and August.If we compare the mean rectal temperature at two periods of the year when the external or weather conditions are approximately the same (April-May and September-October), but when the vitality of the birds, as indicated by the curve of egg-production, moulting, etc., is at a maximum and minimum respectively, we find that the figures are practically identical. This would seem to show that cyclical bodily changes have little effect on body temperature as compared with outside influences.

Abstract. The aim of this study was to evaluate whether an infrared thermometer, a pyrometer, could detect the body surface temperature in the orbital area of gilts without contacting them. Furthermore, it was tested whether an increase in the gilts' temperatures could be detected. Therefore, fever was induced. During 11 trials, 43 German Landrace gilts were injected with either a Porcilis AR-T DF (Intervet International B.V., Boxmeer, Netherlands) vaccine or 2 ml of 0.9 % NaCl. A commercial temperature logger (TRIX-8, LogTag Recorders, Auckland, New Zealand) was placed in the vagina to record temperature data every 3 min. The pyrometer (optris cs, Optris, Berlin, Germany) was aimed at where the orbital area of the gilts would be. While they were drinking, temperature measurements were done in that site by the pyrometer. Time periods from 0.25 to 6 h were analysed. Considering the 0.25-h period, a positive correlation (ρ=0.473) between temperatures of the logger and the pyrometer was found for 15 of 39 gilts. The longer the chosen measuring period was, the fewer animals showed a significant correlation between the two temperatures. In contrast to the vaginal logger, the pyrometer cannot detect an increase in the body temperature in all fever-induced gilts. In conclusion, a pyrometer cannot detect the body surface temperature reliably. An increase in the body surface temperature over a short time period (on average 5 h) could not be detected by the pyrometer. The temperature increase measured using the pyrometer was too low and time-delayed compared to the temperature detected by the vaginal logger.

Since the human body reacts to a variety of different diseases with elevated body temperature, measurement of body temperature remains relevant in clinical practice. The absolute temperature value for fever definition is still arbitrary and depends on the measuring site, as well as underlying disease and individual factors. Hence, a simple threshold for fever definition is outdated and a definition which relies on the relative changes in the individual seems reasonable as it takes these individual factors into account. In this prospective multicentric study we validate an adhesive axillary thermometer (SteadyTemp®) which allows continuous non-invasive temperature measurements. It consists of a patch to measure temperature and a smartphone application to process and visualize gathered data. This article provides information of the new diagnostic possibilities when using this wearable device and where it could be beneficial. Furthermore, it discusses how to interpret the generated data and when it is not practical to use, based on its characteristics and physiological phenomena.

Background - It is difficult to non-invasively phenotype atrial fibrillation (AF) in a way that reflects clinical endpoints such as response to therapy. We set out to map electrical patterns of disorganization and regions of reentrant activity in AF from the body surface using electrocardiographic imaging (ECGI), calibrated to panoramic intracardiac recordings and referenced to AF termination by ablation. Methods - Bi-atrial intracardiac electrograms of 47 AF patients at ablation (30 persistent, 29 male, 63±9 years) were recorded with 64-pole basket catheters and simultaneous 57-lead body surface ECGs. Atrial epicardial electrical activity was reconstructed and organized sites were invasively and non-invasively tracked in 3D using phase singularity (PS). In a subset of 17 patients, sites of AF organization were targeted for ablation. Results - Body surface mapping showed greater AF organization near intracardially-detected drivers than elsewhere, both in PS density (2.3±2.1 vs 1.9±1.6, p=0.02) and number of drivers (3.2±2.3 vs 2.7±1.7, p=0.02). Complexity, defined as the number of stable AF reentrant sites, was concordant between non-invasive and invasive methods (r 2 =0.5, CC=0.71). In the subset receiving targeted ablation, AF complexity showed lower values in those in whom AF terminated than those in whom AF did not terminate (p<0.01). Conclusions - AF complexity tracked non-invasively correlates well with organized and disorganized regions detected by panoramic intracardiac mapping, and correlates with the acute outcome by ablation. This approach may assist in bedside monitoring of therapy or in improving the efficacy of ongoing ablation procedures.

Dalam situasi pandemi Covid-19, roda perekonomian harus tetap berjalan dengan mengedepankan protokol kesehatan. Melansir dari keputusan menteri kesehatan bahwa setiap kantor di Indonesia yang tetap melaksakan Work From Office selama PSBB berlangsung maka harus melakukan pengukuran suhu tubuh, menyediakan hand sanitizer dengan konsentrasi alkohol minimal 70% atau menyediakan sarana cuci tangan di depan pintu masuk. Masalah yang sering terjadi adalah pengukuran suhu tubuh masih dilakukan secara manual oleh satpam kantor, dan tidak terbiasanya para karyawan untuk menggunakan hand sanitizer. Sebagai upaya pendisiplinan karyawan, maka dirancang prototype pintu otomatis yang hanya bisa terbuka jika suhu tubuh normal dan karyawan sudah menggunakan hand sanitizer.   Deteksi suhu tubuh dilakukan menggunakan sensor suhu  MLX90614 dan deteksi objek tangan menggunakan sensor infrared. Pintu geser digerakkan oleh Stepper Motor NEMA 17, pintu secara otomatis akan terbuka ketika suhu terdeteksi normal, jika tidak maka buzzer akan berbunyi dan pintu tetap tertutup. Hasil dari penelitian ini memperoleh hasil pengujian keakuratan sensor suhu MLX90614 sebesar 96.8%, posisi tangan optimal yaitu posisi tangan menengadah dengan jarak 1cm terhadap sensor, dan volume hand sanitizer yang cukup untuk mengcover seluruh telapak tangan dewasa adalah pada delay 500 ms yaitu sebesar 2.2991 gram.   During the Covid-19 pandemic, the economics activities must go on with strict health protocols. From the recommendation of health ministry, that every office in Indonesia that still performs Work From Office during the pandemic, temperature measurements must be carried out at the entrance to the office and hand sanitizer that contains minimum of 70% alcohol or hand washing facilities must be provided as well. The problem is that body temperature measurements are still done manually by security officer, and some employees are still not familiar to use hand sanitizer periodically. As an option to make employees discipline, a prototype of automatic door is designed in this research. It can only open if the body temperature of employee is normal and the employee has used hand sanitizer. Body temperature detection is carried out by using the MLX90614 temperature sensor and hand object detection will utilize infrared sensor. The sliding door is driven by the NEMA 17 Stepper Motor, the door will automatically open when the temperature is detected normally, otherwise the buzzer will sound and the door will be still closed. From the testing results in this research, the accuracy of the MLX90614 temperature sensor is 96.8%, the optimal position of the hand is 1 cm from the sensor with looking up position. And the volume of the hand sanitizer that is sufficient to cover all adult palms with 500 ms delay is 2.2991 grams.

Evidence is presented that sweating is of importance to cattle as a method of regulating body temperature in a hot, dry environment. Cattle were covered with polyethylene coats, which prevented the vaporization of skin moisture from the body surface. They were then exposed to high atmospheric temperatures. Significant differences (P < 0.001) between their rectal temperatures and those of the control animals were demonstrated. It is concluded that, in conditions of high air temperature and radiation and low humidity, differences in heat tolerance between one animal and another may be due to differences in the ability to dissipate heat in the vaporization of sweat on the skin surface.

Non-invasive techniques can be applied for monitoring the physiology and behaviour of wildlife in Zoos to improve management and welfare. Thermal imaging technology has been used as a non-invasive technique to measure the body temperature of various domesticated and wildlife species. In this study, we evaluated the application of thermal imaging to measure the body temperature of koalas (Phascolarctos cinereus) in a Zoo environment. The aim of the study was to determine the body feature most suitable for recording a koala’s body temperature (using coefficient of variation scores). We used a FLIR530TM IR thermal imaging camera to take images of each individual koala across three days in autumn 2018 at the Wildlife Sydney Zoo, Australia. Our results demonstrated that koalas had more than one reliable body feature for recording body temperature using the thermal imaging tool—the most reliable features were eyes and abdomen. This study provides first reported application of thermal imaging on an Australian native species in a Zoo and demonstrates its potential applicability as a humane/non-invasive technique for assessing the body temperature as an index of stress.
