Water - as moisture, has an essential role in all biochemical processes of plants; vital occurring a vegetative organism can proceed normally only under the condition sufficient saturation cages by moisture. Results theoretical researches on dynamics ground humidity have shown: (1) similarity physical change soil different irrigated areas (2) hysteresis nature at irrigation and drainage. (3) sh...

With the three-dimensional field of velocity predicted by numerical methods it is possible to predict the moisture distribution and hence the occurrence of large-scale saturation. A three-parameter model was used to predict the 12-hour precipitation for the early stages of the storms of November 24, 1950 and November 5, 1953, neglecting cloud storage, supersaturation, a possible lack of condens...

Drying of solid particles is generally divided into three periods: a short initial heating period, a constant drying rate period, and a falling drying rate period. Drying in a fixed under various drying conditions was experimentally studied. The main goals of the measurements were to calculate the heat transfer coefficient based on the measured values, and to evaluate the validity of the consta...

Atmospheric water vapour is an essential ingredient of weather and climate. The key features of its distribution can be represented by kinematic models which treat it as a passive scalar advected by a prescribed flow and reacting through condensation. Condensation acts as a sink that maintains specific humidity below a prescribed, space-dependent saturation value. To investigate how the interpl...

Little is known about biophysical controls on soil respiration in California’s Sierra Nevada oldgrowth, mixed-conifer forests. Using portable and automated soil respiration sampling units, we measured soil respiration rate (SRR) in three dominant patch types: closed canopy (CC), ceanothus-dominated patches (CECO), and open canopy (OC). SRR varied significantly among the patch types, ranging fro...

E€ective control of nonpoint source pollution from contaminants transported by runo€ requires information about the source areas of surface runo€. Variable source hydrology is widely recognized by hydrologists, yet few methods exist for identifying the saturated areas that generate most runo€ in humid regions. The Soil Moisture Routing model is a daily water balance model that simulates the hyd...

Soldering of molded case tantalum capacitors can result in damage to Ta2O5 dielectric and first turn-on failures due to thermo-mechanical stresses caused by CTE mismatch between materials used in the capacitors. It is also known that presence of moisture might cause damage to plastic cases due to the pop-corning effect. However, there are only scarce literature data on the effect of moisture co...

In this study, beech wood was treated in hot oil and in hot air to determine the differences in the effects of the two processes on the physical properties of the wood. Heat treatment was conducted at temperatures of 160, 190, and 220 °C for 2 h at atmospheric pressure. After the heat treatment, various properties of the wood, including mass increase in hot oil treatment (wt% gain), mass loss i...

Wearable sensor systems have become promising tools in modern health care. Vital signs are recored to monitor the condition of a subject in a continuous manner. In order to assess sports performance and optimize training, as much as possible information on the athlethes condition is helpful. We present a wearable and disposable sensor that measures heart rate, oxygen saturation, pH value, skin ...
