Lacking prior significant genetic association information related to the cannabis use phenotypes, SNPs were assigned equal weights in the estimation process and the gene-based tests were conducted genomewide for both phenotypes.
To study the biological significance of differentially expressed genes, gene ontology (GO) based enrichment tests were conducted using a web based tool GOMiner [ 50] (http://discover.nci.nih.gov/gominer/index.jsp).jsp
To further improve the separation performance and evaluate the silica-based media, DMC separation tests were conducted based on a statistically designed program to identify the role of various operational parameters (i.e. medium relative density, silica media blend ratio, and cyclone apex diameter) in maximizing organic efficiency and minimizing low-density bypass.
To investigate the fatigue fracture mechanism in spot welded joints using a 590 MPa-class base metal, fatigue tests were conducted under constant loading conditions.
A series of laboratory tests were conducted based on the step-by-step design procedure developed.
First, a series of single-stage quenching tests were conducted based on the end quenching equipment.
In this research, two sets of sliding wear tests were conducted based on the Taguchi L27 orthogonal array (OA) and their results were analyzed using grey relational analysis.
The DCB tests were conducted based on ASTM D3433 [21] using a tensile test machine (Compact Table-Top Universal/Tensile Tester, EZ-S, produced by the Shimadzu Corporation, Japan) at a crosshead speed of 0.5 mm/min.
To study the wear behaviors of the tunnel boring machine (TBM) disc cutter ring under drying, water and seawater conditions, a series of cutter-rock wear tests were conducted based on the self-designed TBM cutter performance test bench.
Additionally, 12 types of rocks, including Granite, Marble and Travertine were collected and studied and laboratory tests were conducted based on physical and mechanical properties for evaluating sawing machine vibration from Iranian quarries.
All these tests were conducted based on recommendation of the OECD guidelines [ 19– 22].
