Experimental Models and Programs Whatever the form grinding is used the interaction between abrasive grinding wheel and workpiece surface to removal of surface material.
In the same wheel speed sv , workpiece speed wv , grinding depth pa , the cutting times, the same material and size for grinding the workpiece
In the dry grinding process, because there is no lubrication material, grinding wheel and workpiece surface roughness caused by dry friction maximum.

Keloids are actually accumulations of dermal material building up during prolonged wound healing processes.
Material and Method Starting from the wound healing model, we suggest a mathematical model is based on the competition against various types of cells, which relies on the kinetic theory for active particles described in [4,5].The mathematical methods of kinetic theory may be used to develop a series of models described by equations able to characterize particle behavior as a whole starting from a microscopic interaction description.
The suggested model simulates scar formation function evolution, which is a new function in living matter tribology, namely wear due to the added material.

Performance Evaluation of the Horizontal Subsurface Flow Constructed Wetland with Ipomoea aquaticaplantfor Rural Domestic Wastewater Treatment Ahmed Mohammed Osman1,2,a, Lu- Xiwu*1,b 1Environmental science and Engineering Department, Southeast University, Nanjing 210096, China 2Civil Engineering Department, Karary University, Khartoum 12304, Sudan aEmail:ahmedosm77@yahoo.com; *bEmail: luxiwu@seu.edu.cn Keywords:Ipomoea aquatica; Horizontal subsurface flow constructed wetland; Hydraulic loading rate; Nutrients.
The constructed wetlands (CWs)  are widely used worldwide to accomplish secondary and tertiary treatment of the domestic, municipal, and industrial wastewaters [2].The CWs offers an attractive option to wastewater treatment with efficient and less energy intensive, low operation costs and maintenance requirements, and they are more aesthetically pleasing compared with conventional wastewater treatment systems [3-6].Many of contaminants such as organic material, nutrient, total coliforms, and heavy metals can be removed from the wastewater by CWs via sedimentation, coagulation, adsorption, filtration, plant uptake, and microbial transformation[7-9].Some factors have effect on the CWs performance such as hydraulic loading rate (HLR), constructed wetland configuration and vegetation type[10].The HSFCWis suitable treatment systemused for cold climates becausewastewater treatment occurs below the surface [11].It is the most common CW systems used in worldwide especially in Europe [12].
In this study, the HSFCW planted with Ipomoea aquatica(Chinese spinach)was applied as a tertiary treatment to evaluate their performance on the organic material and nutrients removal efficiency.The integrated system schematic diagram is shown in Fig.1.
Material and methods Constructed wetland setup and experimental procedures The experimental system was made up of the HSFCW system as a rectangular basin with dimensions of 2.3 m (L) ×0.6m (W) × 0. 4m (D) and thebed slope is 0.5%.

Welding parameters such as the capacity and type of equipment, material dimensions and composition may be relatively fixed, while primary adjustable parameters, which are characterized by welding speed, arc voltage and welding current, may be altered during the arc welding process.
The 150x200x4.5mm SS400 materials and steel wire with a diameter of 1.2mm were employed for the experiment.
