The existing hardware circuits can only measure a single point temperature in a small range owing to the influence of extremely little output voltage and the poor linear degrees of thermocouple on testing temperature ,and it is difficult to meet the demand of practical use because of its low measurement precision . This system realized accurate measurement of multipoint temperature in a large range using optimization design to overcome the above-mentioned defects,, It uses low maladjustment and high precision operation amplifier ADOP07 to constitute the inphase and shunt-wound difference amplification circuit to carry out non-electric measurement of thermocouple It also uses the CD4051 chip to compose the switch circuit at different time in order to realize the measurement of multi-thermocouple ,and the ICAD538 is used to implement square operation in order to make linear compensation of temperature , finally sends the measurement value to single-chip computer through A/D converter to process data which is controlled by the application of modern fuzzy controlling theory so as to reach the aim of precise measurement and control. The experiments show the system can realize accurate measurement of multipoint temperature in a wide from 20 to 400°C, and the experimental results are satisfying

BACKGROUND As of the end of February 2020, 2019-nCoV is currently well controlled in China. However, the virus is now spreading globally. OBJECTIVE This study aimed to evaluate the effectiveness of outbreak prevention and control measures in a region. METHODS A model is built for find the best fit for two sets of data (the number of daily new diagnosed, and the risk value of incoming immigration population). The parameters (offset and time window) in the model can be used as the evaluation of effectiveness of outbreak prevention and control. RESULTS Through study, it is found that the parameter offset and time window in the model can accurately reflect the prevention effectiveness. Some related data and public news confirm this result. And this method has advantages over the method using R0 in two aspects. CONCLUSIONS If the epidemic situation is well controlled, the virus is not terrible. Now the daily new diagnosed patients in most regions of China is quickly reduced to zero or close to zero. Chinese can do a good job in the face of huge epidemic pressure. Therefore, if other countries can do well in prevention and control, the epidemic in those places can also pass quickly.

Moderate Exercise Intensity

Background: While increased face mask use has helped reduce COVID-19 transmission, there have been concerns about its influence on thermoregulation during exercise in the heat, but consistent, evidence-based recommendations are lacking. Hypothesis: No physiological differences would exist during low-to-moderate exercise intensity in the heat between trials with and without face masks, but perceptual sensations could vary. Study Design: Crossover study. Level of Evidence: Level 2. Methods: Twelve physically active participants (8 male, 4 female; age = 24 ± 3 years) completed 4 face mask trials and 1 control trial (no mask) in the heat (32.3°C ± 0.04°C; 54.4% ± 0.7% relative humidity [RH]). The protocol was 60 minutes of walking and jogging between 35% and 60% of relative VO2max. Rectal temperature (Trec), heart rate (HR), temperature and humidity inside and outside of the face mask (Tmicro_in, Tmicro_out, RHmicro_in, RHmicro_out) and perceptual variables (rating of perceived exertion (RPE), thermal sensation, thirst sensation, fatigue level, and overall breathing discomfort) were monitored throughout all trials. Results: Mean Trec and HR increased at 30- and 60-minute time points compared with 0-minute time points, but no difference existed between face mask trials and control trials ( P > 0.05). Mean Tmicro_in, RHmicro_in, and humidity difference inside and outside of the face mask (ΔRHmicro) were significantly different between face mask trials ( P < 0.05). There was no significant difference in perceptual variables between face mask trials and control trials ( P > 0.05), except overall breathing discomfort ( P < 0.01). Higher RHmicro_in, RPE, and thermal sensation significantly predicted higher overall breathing discomfort ( r2 = 0.418; P < 0.01). Conclusion: Face mask use during 60 minutes of low-to-moderate exercise intensity in the heat did not significantly affect Trec or HR. Although face mask use may affect overall breathing discomfort due to the changes in the face mask microenvironment, face mask use itself did not cause an increase in whole body thermal stress. Clinical Relevance: Face mask use is feasible and safe during exercise in the heat, at low-to-moderate exercise intensities, for physically active, healthy individuals.

Background: Legal assisted dying is a rare event, but as legalisation expands, requests for it will likely increase, and the nurse most often receives the informal, initial request. Objectives: To assess the effects of attitude in interaction with normative and control beliefs on an intention to respond to a request for legal assisted dying. Ethical considerations: The study had the lead author’s institutional ethics approval, and participants were informed that participation was both anonymous and voluntary. Methodology: This was a cross-sectional correlational study of 377 Australian registered nurses who completed an online survey. Generalised linear modelling assessed the effects of independent variables against intended responses to requests for legal assisted dying. Results: Compared to nurses who did not support legal assisted dying, nurses who did had stronger beliefs in patient rights, perceived social expectations to refer the request and stronger control in that intention. Nurses who did not support legal assisted dying had stronger beliefs in ethics of duty to the patient and often held dual intentions to discuss the request with the patient but also held an intention to deflect the request to consideration of alternatives. Discussion: This study advances the international literature by developing quantified models explaining the complexity of nurses’ experiences with requests for an assisted death. Attitude was operationalised in interaction with other beliefs and was identified as the strongest influence on intentions, but significantly moderated by ethical norms. Conclusion: The complex of determinants of those intentions to respond to requests for an assisted death suggests they are not isolated from each other. Nurses might have distinct intentions, but they can also hold multiple intentions even when they prioritise one. These findings present opportunities to prepare nurses in a way that enhances moral resilience in the face of complex moral encounters.

We preliminarily designed a power tracking and control system using single-chip computers and industrial control computer in the electric heating simulated power loop. The system is an innovational design based on the proven simulated nuclear power loop, with increased techniques of step-less power regulation system and modeling nuclear feedback effect correctional programs. We promoted both hardware and software designs of this power tracking and control system in this paper. It used single-chip computers as the core control chips and an industrial control computer as the additional correctional program and record carrier. The process and implementation of the control software are presented, which is designed as a fuzzy theoretical nonlinear system. In order to ensure the subsequent updates, the access interface of the system is open for following correctional programs, including the correctional program of void fraction effect, temperature effect, hysteresis effect and heat power distribution effect. Taken hysteresis effect correctional program as an example, we use an offset tic-tac clock replacing the inherent tic-tac clock in different devices of the system in order to reduce the hysteresis effect of measuring and corresponding errors. We also put out a preliminary analysis of the accurate synchronization for the system at the end of the paper.
