developing a rapid, nondestructive and reliable method to measure moisture content of date fruit is of interest in pre- and post-harvest processes of this valuable product. throughout this research, by putting date palm fruits (cv. mazafati) in a parallel plate capacitor, the sinusoidal alternative voltage in the frequency range of 1 to 100 mhz was exerted to the dates and the response of the c...

Efforts by several investigators to measure availability of water to plants by vapor pressure (2, 12) and other methods (10, 14) have indicated that the potential of water at the permanent wilting percentage is approximately 16 x 106 ergs per gram, whereas others (1, 11) have obtained results which indicate somewhat lower values. A great many experiments (3, 4, 5, 6, 13) have demonstrated that ...

Time domain reflectometry (TDR) is a prospective measurement technology for moisture content of sewage sludge composting material; however, a significant dependence upon temperature has been observed. The objective of this study was to assess the impacts of temperature upon moisture content measurement and determine if TDR could be used to monitor moisture content in sewage sludge compost acros...

In jaggery making furnaces, sugarcane bagasse is used as fuel. Moisture content of bagasse affects its calorific value. So burning of bagasse at suitable level of moisture is essential from the viewpoint of furnace performance. Moisture content can also be used for indirect calculation of fibre content in sugarcane. Normally gravimetric method is used for moisture content determination, which i...

to design the equipment and facilities for preservation, storage and processing of pomegranate, it is necessary to know the specific heat and thermal conductivity of the fruit components. the specific heat of exocarp, mesocarp and of seeds of pomegranate were assessed at three moisture content levels (30, 50 and 76% for seed and mesocarp; 15, 35 and 52% for exocarp) and at four temperature leve...

A series of microcosm experiments were performed to determine the effectiveness of various gaseous electron donors (including hydrogen, 1-hexene, ethyl acetate, and liquefied petroleum gas [LPG]) for supporting biological perchlorate reduction under different electron donor concentrations and soil moistures. Under high soil moisture (16% w/w) conditions, complete or partial perchlorate degradat...

Moisture content and water activity are key parameters in predicting the stability of low moisture content products. However, conventional methods for moisture content and water activity determination (e.g., loss on drying method, ‎Karl Fischer titration, dew point method) are time consuming, demand specialized equipment and are not amenable to online processing. For this reason they are typica...

Sphagnum (spp.) is widely distributed in permafrost regions around the arctic and subarctic. The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevant, in general terms, to permafrost thaw (therrnokarst). In this study, we test and calibrate seve...

The object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. The evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. The results revealed that the effect of soil moisture content was only significant on...
