In industrial technological processes associated with the heating of the processed material by microwave radiation, it is necessary to measure the temperatures of objects. Methods for measuring temperatures in the fields of technology using microwave heating systems are considered. The main possibilities, disadvantages and limitations of the used contact and non-contact (optical) measurement methods are determined. The requirements for temperature measurement systems under conditions of exposure to strong electromagnetic fields are listed. The possibilities of the spectral pyrometry method are especially noted.

Introduction: The aim of this survey was to investigate the current knowledge, attitudes, and practices of febrile children’s caregivers about fever, antipyretic usage, and temperature measurement methods in a tertiary care hospital. Methodology: A 41-item questionnaire was administered to a convenience sample of febrile children’s caregivers in face-to-face interviews by two research assistants from January 2012 through June 2012 in an urban region of Turkey. Results: A total of 1,032 caregivers completed the interview. Approximately one-third of caregivers considered a temperature of less than 37.8°C (100°F) to be a fever, and 13% of all respondents would give antipyretics for a body temperature ≤ 37.8°C. Furthermore, 76% of parents would wake their children from sleep to administer antipyretics. Although a high proportion (89.5%) of respondents believed that fever had harmful effects, 10.5% considered fever to be beneficial. Alternating use of acetaminophen and ibuprofen (44%) and giving antipyretics routinely (71%) before and after immunizations were common parental practices and generally advised by pediatricians. Parents with higher levels of education were more likely to consider fever to be beneficial and to treat fever with antipyretics, and less likely to seek medical attention for mild fever. Most caregivers stated that they were unsure about the right site (90%) and thermometer type (95%) for temperature measurement. Conclusions: Persistent fever anxiety and excessive antipyretic usage may be heightened by the lack of knowledge regarding accurate temperature measurement methods with digital thermometers in our population. Parental education may positively affect the approach to fever and antipyretic usage.

In microwave-assisted organic synthesis, the question of microwave effects is still debated. Proper examination of these hypothesized phenomena is encumbered by some specific features of microwave heating. We devise a convenient method to eliminate most of the irreproducibility observed in microwave-heated organic transformations by thermal conditioning of the microwave reactor cavity. To show the utility of this approach, we investigated a reaction of 2-chloropyridine, in which microwave conditions were shown to be beneficial by previous studies. Using our method to ensure proper reproducibility together with fibre optic temperature measurement, the observed differences were traced back to large hidden thermal differences, while non-thermal effects could not be detected in the comparison experiments.

Temperature measurement methods always including contact method and non-contact method, generally speaking, non-contact method used for detecting remote measuring objects temperature, in especially as to particular occasions such as factory workshop. This paper provides a system based FPGA(field programmable gate array)for accurate measure and analysis long distance objects temperature. The system could be used in process of industrial produce fabrication.
