Ultrasonic and Cooling Approaches for Reinforcement of the Microextraction Methods

Since solid-phase and liquid-phase microextraction (SPME and LPME) were introduced, as effective solvent-free methods, many efforts have been made to improve their modes and applications. However, due to limitations with sensitivity and efficiency, researchers have focused on improving the performance of their basic primary modes. In this way, in recent years, different methods such as ultrason...

Effect of Varying Rates of Organic Amendments on Porosity and Infiltration Rate of Sandy Loam Soil

Infiltration rate and porosity of sandy loam soil amended separately with goatyard manure (GYM) and poultry waste at 30, 50 and 70 tonnes/hectare each were investigated and the results were statistically analyzed using SPSS ver 17 package. Infiltration rates under GYM amendment and poultry waste amendment showed significant difference (p≤0.01), indicating that the variation of infiltration unde...

Theoretical and Test Study on Dynamic Characteristics of Thin-Layered Sandy Frozen Soil in Blasting

In order to understand the stress changes of various points in sandy frozen soil, tension-compression conversion, fissure development on the surface, the rupture process, the expansion speed and scope of frozen soil duing blasting, the dynamic characteristics of thin-layered sandy frozen soil were analyzed in this paper. The blasting process of frozen soil is regarded as a dynamic pressure oper...
