Packing density and moisture content are important factors in investigating the ensiling quality. Low packing density is a major cause of loss of sugar content. The moisture content also plays a determinant role in biomass degradation. To comprehensively evaluate the ensiling quality, this study focused on developing a compound sensor. In it, moisture electrodes and strain gauges were embedded ...

A sensitive and simple color sensor for indole vapors has been developed based on the Ehrlich-type reaction in solid polymer film. Upon 60-min exposure of the film sensor to the air containing 5 - 100 ppb of indole vapors, pink or magenta color could be recognized by the naked eyes. Alternatively, a trial gas detector tube has been prepared by mixing the reagents with sea sand. When air (100 mL...

Diazinon is commonly used for pest control in the agricultural fields because of its relatively low cost and high efficiency. Due to the increasing application of pesticides, reliable and accurate analytical methods are necessary for their monitoring. This work was aimed to design the high selective electrochemical sensor for determining of diazinon in biological and environmental samples. The ...

This paper aims in providing a user friendly, reliable and automated water pumping system. The paper aims in designing a system which is capable of detecting moisture level in the soil and capable of taking the decision of switching ON/OFF water pump. The system also uses temperature sensor to detect the temperature and automatically the fan speed can be controlled like coolants. In this paper ...

Isotherm curves are useful for the designing of dryer as well as controling of the seed moisture content during storage and drying process. To study the curves, this research was performed on the basis of two factorial experiments including three factors: (1) hybrid at two levels (Three Way Cross 647 and Single Cross 704) (2) temperature at 6 levels (from 5 to 55°C) and (3) Relative Humidity (R...

5 The diagnostic evaluation of moisture budgets in archived atmosphere model data is examined. 6 Sources of error in diagnostic computation can arise from the use of numerical methods dif7 ferent to those used in the atmosphere model, the time and vertical resolution of the archived 8 data and data availability. These sources of error are assessed using the climatological mois9 ture balance in ...

Dehydration of Mazafati Rutab is a method to prevent its spoilage. Dehydration is necessary for Mazafati Rutab because it contains too much moisture. If the moisture content of Mazafati Rutab is decreased properly, it need not be stored under refrigeration. The present study was carried out in an attempt to decrease the moisture content in order to increase the shelf life of Mazafati dates. Sam...

In a variety of agricultural activities, such as irrigation scheduling and nutrient management, soil water content is regarded as an essential parameter. Either power supply or long-distance cable is hardly available within field scale. For the necessity of monitoring soil water dynamics at field scale, this study presents a wireless soil moisture sensor based on the impedance transform of the ...
