AbstractAbstract
[en] Exact observance of the water to cement ratio results in a constant quality of concrete on the one hand and in saving of cement on the other. To this end a module has been developed containing a neutron moisture gage and a water feeder. So, the moisture of the additives can be measured continuously and the quantity of water required can be added automatically. Saving of cement of more than 10 kg per m3 of wet concrete is possible. The installation of the module is only useful in concrete plants with a certain standard of automation

AbstractAbstract
[en] The purpose of this paper is to develop and document a position on Relative Humidity (RH) requirements in the WSCF Laboratories. A current survey of equipment vendors for Organic, Inorganic and Radiochemical laboratories indicate that 25% - 80% relative humidity may meet the environmental requirements for safe operation and protection of all the laboratory equipment

AbstractAbstract
[en] Checking the quality of live steam is an essential prerequisite for a careful mode of operation of a saturated steam turbine. For this purpose a steam moisture measurement system has been developed and introduced into the nuclear industry. In this article, the principle of measurement, parameters of the steam moisture probe, electronic data processing, operating instructions, and economical advantages are briefly discussed

AbstractAbstract
[en] One of the options possible to reduce the CO2 emissions is the CO2 capture and sequestration in the coal layer with simultaneous methane production. This work presents the experimental isotherms of the adsorption on dry and humid coal at two temperatures (45 C and 70 C). The influence of the humidity is very important: at 45 C the CO2 adsorption capacities are reduced of more than 40% and more tan 70% for the CH4. (A.L.B.)

AbstractAbstract
[en] The aim of present research was to measure and analyze the dynamic changes of internal pressure in shrinking vs. non-shrinking materials during convective drying for the use as a possible process control method. Drying experiments were carried out on wet and fired clay at 50°C and 60°C. In addition, the shrinkage curve was investigated. Experimental measurements show the existence of 4 stages of the process. The comparison of the results for wet and fired clay shows differences in pressure trends. During drying the internal pressure changes from underpressure to overpressure at the level of 3÷5kPa, what correlates well with transition from the first to the second drying period. (Author)

AbstractAbstract
[en] This paper investigated moisture related comfort properties of woven fabrics from natural cellulosic fibers, namely cotton, linen, and Crailar. The comfort properties of the fabrics were measured in accordance with the relevant standards, and the results were comparatively discussed. In addition to that, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) together with Analytic Hierarchy Process (AHP) was employed to determine the most preferable fabric based on comfort properties.

AbstractAbstract
[en] Electrostatic collection technique is widely used in various radon monitors. The mechanism of this kind of radon monitor is that the positive Po particles, produced by decay of radon, can be collected on the surface of detector in electric field. Collection efficiency, therefore, could be affected by air humidity. Calibration under different humidity conditions or test of humidity response is necessary consequently. In this study, a humidity control technique based on Nafion membrane tube (NMT) is developed. Under a consistent flowrate with a certain stable level of radon concentration and humidity of main-path inlet, the humidity of outlet sample gas from the main-path can be adjusted and stably controlled at a certain level by changing side-path's flowrates of NMT. By adjusting main and side-path flowrate, RH of outlet gas of the main-path can be controlled from 5.3 to 80.0%. Theoretical study were also performed. Based on this, humidity influence calibration of an electrostatic radon monitor was performed, and a relationship between the sensitivity of the radon monitor and relative humidity was obtained.

AbstractAbstract
[en] Some preliminary results of the effects of moisture content on volume emanation rates and emanation coefficients are presented for core and crushed samples of cemented tailings. The volume emanation rates increased with increasing moisture content, with saturated core samples emanating about 3 times as much as dry material. There was a similar increase in coefficient for the crushed cemented tailings

AbstractAbstract
[en] In the present study, various solar and atmospheric parameters, namely solar radiation, surface ozone, relative humidity, air temperature, and wind speed, have been studied first time for the annular solar eclipse of June 21, 2020, at seven Indian stations simultaneously. All the seven different stations are selected along the solar eclipse path having the maximum eclipse magnitude of 92% and above. The various atmospheric parameters have shown the change in behavior during the solar eclipse duration. The incoming solar radiation has a maximum 95.97% decrease at Ludhiana at the time of maximum obscuration compared to the previous day. The surface ozone concentration has shown a decrease for all the seven stations during the maximum obscuration period. A maximum of 9.25% decrease in surface temperature has been observed nearly after 30 min of the time of maximum obscuration of the eclipse. Relative humidity started increasing at all the stations and showed an inverse trend from temperature. The wind speed was found to suppress during the maximum solar eclipse which may be attributed to stabilization of atmospheric boundary layer due to cooling. (author)
