[en] Since with beginning damage to a slide bearing the conversion of mechanical energy to heat increases a special integral temperature sensor has been installed in the critical part over the whole breadth of the bearing. With this, any temperature rise in a 'bad' bearing - also in the case of changes in ambient temperature or load - can be recorded by comparison. The procedure has been developed for turbine bearings, but it may be applied to bearings of engines, agricultural machines, pumps, and cooling devices, too. (author)

[en] To control the radiation processing in the high dose range one of the dosimetric systems more employed as routine dosimeters are the Perspex, due that it is a reliable system, of easy manipulation and quick measurement. In this system, at the same as another, the response is affected for several factors, it which produce an overestimation in the absorbed dose value if they are not take account. In the present paper was studied the influence of the irradiation temperature and the post-irradiation time in the absorbed dose value of the Red 4034 Perspex dosimeters Batch EN, it which would allow us to obtain accurate absorbed dose value in the radiation processing control

[en] A high-resolution objective analysis has been applied to conventional and satellite retrieved temperature profiles to investigate differences among the two sets of data. The case study selected represents the first stages of a rapid cyclone development in the lee of the Alps. It is found, both in statistical and qualitative terms, that satellite data are in good agreement with conventional ones and that a detailed description of the temperature field at surfaces is of primary importance for an accurate retrieval of satellite soundings, particularly for use in mesoscale meteorology. The time lag between the two different data sets is found to explain a consistent portion of the discrepancies and therefore a full quadridimensional assimilation scheme appears to be essential to pursue the investigation

[en] At thousands of stations worldwide, the mean daily surface air temperature is estimated as a mean of the daily maximum (T_max) and minimum (T_min) temperatures. We use the NOAA Surface Radiation Budget Network (SURFRAD) of seven US stations with surface air temperature recorded each minute to assess the accuracy of the mean daily temperature estimate as an average of the daily maximum and minimum temperatures and to investigate how the accuracy of the estimate increases with an increasing number of daily temperature observations. We find the average difference between the estimate based on an average of the maximum and minimum temperatures and the average of 1440 1-min daily observations to be − 0.05 ± 1.56 °C, based on analyses of a sample of 238 days of temperature observations. Considering determination of the daily mean temperature based on 3, 4, 6, 12, or 24 daily temperature observations, we find that 2, 4, or 6 daily observations do not reduce significantly the uncertainty of the daily mean temperature. The bias reduction in a statistically significant manner (95% confidence level) occurs only with 12 or 24 daily observations. The daily mean temperature determination based on 24 hourly observations reduces the sample daily temperature uncertainty to − 0.01 ± 0.20 °C. Estimating the parameters of population of all SURFRAD observations, the 95% confidence intervals based on 24 hourly measurements is from − 0.025 to 0.004 °C, compared to a confidence interval from − 0.15 to 0.05 °C based on the mean of T_max and T_min.
