the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Origins of abnormal behaviors of gelatinous layer in tension wood fiber - A micromechanical approach
The mechanism responsible for unusual mechanical properties of tension wood gelatinous fiber (Gfiber) was investigated. We discussed origins of high tensile growth stress, high drying shrinkage, and rapid increase of Young’s modulus due to drying, in association with microscopic structure of gelatinous layer (G-layer). Anatomical, crystallographic, and micromechanical approaches were employed. ...

in this study thin layer drying of corn in a convective dryer was investigated at air temperatures of 50, 60 and 70ºc and air flow rates of 1, 1.4 and 1.8 kg min-1. experiments were performed in completely randomized design (crd). the effect of air temperature and flow rate on drying time, drying rate, effective diffusivity coefficient and activation energy were studied. results showed that the...
Extended Abstract Introduction and Objective: Due to population growth and increasing demand for protein sources, poultry farming became industrialized. This has increased the density of breeding per unit area and also increased the likelihood of disease in them. However, the spread of diseases has led to a greater tendency to use antibiotics. Therefore, one of the ways to reduce the use of an...
Convective drying of atmospheric pressure cold plasma pretreatment saffron stigmas: kinetic modeling
In this study, the drying kinetics of saffron stigmas pretreated by atmospheric pressure cold plasma pretreatment (15, 30, 45 and 60 s) followed by hot air drying (60°C and 1.5 m/s) were modeled using 10 conventional mathematical thin layer models. The use of cold plasma pretreatment reduced drying time and enhanced effective moisture diffusivity (Deff). The most accurate models describing beha...
The potential utilization of encapsulation techniques in food, pharmaceutical and agricultural products preparation, presents a new alternative for complementary technologies such as targeting delivery vehicles and carriers for active food ingredients. Encapsulation could be accomplished by different techniques like: simple or complex coacervation, emulsification technique, phase separation, sp...
