Leaf Area Index - an overview | ScienceDirect Topics.

H. Fang, S. Liang, in Reference Module in Earth Systems and Environmental Sciences, 2014 Leaf area index (LAI), one half the total green leaf area per unit horizontal ground surface, is an important structural property of vegetation. Because leaf surfaces are the primary border of energy and mass exchange, important processes such as canopy interception, ....

Hagen-Poiseuille Equation - an overview | ScienceDirect Topics.

S=specific area (total surface area of the particles per unit volume of cake, m -1) K=an empirical coefficient, depending of particle shape distribution, dimensionless. Comparing the Karman-Kozeny model with Darcy's law, an expression for the specific resistance of the cake is obtained, as shown in Eq..

Rubber Compounding - an overview | ScienceDirect Topics.

Maziar Ramezani, Zaidi M. Ripin, in Rubber-Pad Forming Processes, 2012. 3.3 Compounding. Rubber compounding or formulation refers to the addition of certain chemicals to raw rubber in order to obtain the desired properties. The well-known chemicals are crosslinking agents, reinforcements, anti degradants and colorants. The crosslinking agents are required for ....

Specific Gas Constant - an overview | ScienceDirect Topics.

As stated above, the PIR is the calculated number, and it is the product of square root of the square of pipe diameter, and pressure which is factored by the specific gas constant of the pipeline in Eq. 0.69 is used to calculate the PIR of natural gas; for other gases, this factor would be different and can be obtained from the discussion about the derivation of the PIR calculation ....

Insect Farming - an overview | ScienceDirect Topics.

R.T. Gahukar, in Insects as Sustainable Food Ingredients, 2016 Industrial Perspective. Insect farming in a closed or indoor environment is an important means to making food available continuously year-round, since many insects are available in nature only during certain seasons or months. It is particularly important to increase scale (as well as lower cost) and efficiency of ....

Gas Sensor - an overview | ScienceDirect Topics.

One example is the silica flake shell with metalloporphyrin on its surface (Fig. 3.4) [13]. This receptor material was used to detect acetone at low concentration of 50 ppm with a high signal-to-noise ratio. The sensitivity to acetone was enhanced owing to the large surface area of the receptor materials..
