A finite element model for analyzing the strain-stress field of laser cladding process was built and the process with powder feeding was analyzed with the model. Temperature variation during cladding described in Part I was applied as “body force” loads in the strain-stress analysis. The analysis result shows that, by the end of cladding, the(More)
Laser cladding consists of covering a substrate surface with a coating of a different nature. As a complex thermal-mechanical process, laser cladding is not quite understood yet. In this study, a finite element model for analyzing the temperature field was built and the laser cladding process with powder feeding was analyzed with the model. The analysis(More)
The general macroscopic examination of semen evaluation includes sperm density, concentration, motility and morphology. Among these general evaluations, the morphology assessment is widely considered to be one of the most important evaluations of male sperm characteristics. With the use of computer-assisted sperm analysis (CASA) techniques, more objective,(More)
a sequencing batch reactor (SBR) was used to treat synthetic wastewater when dissolved oxygen (DO) concentration and temperature were 0.5-1.0mg/L, and 30±1¿ respectively. Effect of COD/NH4+-N and influent pH on simultaneous nitrification and denitrification (SND) were investigated. The results indicated that removal efficiencies of ammonia nitrogen(More)
S100 Ca2+-binding protein A1 (S100A1) is an important regulator of myocardial contractility. The aim of the present study was to identify the underlying mechanisms of S100A1 activity via profiling the protein expression in rats administered with an S100A1 adenovirus (Ad‑S100A1‑EGFP) following acute myocardial infarction (AMI). LTQ OrbiTrap mass spectrometry(More)
For 3-D ultrasound imaging, the row-column addressing (RCA) with 2N connections for an N × N 2-D array makes the fabrication and interconnection simpler than the fully addressing with N² connections. However, RCA degrades the image quality because of defocusing in signal channel direction in the transmit event. To solve this problem, a split row-column(More)
