However, multiplication rates are very low and it is difficult to obtain enough planting material because of the large size (>50 cm lengths) of the cuttings required [8].
This technique could produce large numbers of clonal plants in a short time period by using very small amount of starting material [9].
Tissue culture is an efficient method for rapid propagation of plants in order to obtain healthy plants without pathogen in a short time and minimal space with very few starting materials [10].

Introduction Magnesium based alloys have proven to be highly competitive materials for various applications where weight is the important parameter.
The comparison between the measurements and the calculations shows that the method used in this study can be used for prediction of mass transfer phenomena and further application in the hydrogen/magnesium system. 0 15 30 45 60 75 90 -7 -6 -5 -4 -3 -2 -1 0 ln[(CO2-CO2e)/(C o O2-CO2e)] 100rpm+550cc/min 160rpm 200rpm 280rpm Diff.100rpm+550cc/min 160rpm 200rpm 280rpm Time(min)8 Title of Publication (to be inserted by the publisher) Acknowledgment The authors are grateful for the support provided by a research grant from Korea Ministry of Science and Technology (MOST) G7 project and INHA UNIVERSITY research grant through the Special Research Program.

As a primary raw material - some kinds of strip steel are used by some important industries, such as military affairs, aviation and spaceflight, shipbuilding industry; it also has been used extensively in many other fields of people living product, for example, automotive and electronics industries and so on.
When received indent, enterprises make material quality plan by material requirements of consumer, including quality standard of product surface, bringing forward different process criterion, prescribing different parameter of production control and demand of performance detection.
Because of the steel enterprise's ever-present defects and defect rang of our lab system of defects inspection on-line to inspect defects, there are ten kinds of defects confirmed to assessing grade, including Scratch Strip (Fig.1), Holes (Fig.2), Roll Marks (Fig.3), Pits (Fig.4), Mixed Material (Fig.5), Blisters (Fig.6), Shell, Extraneous Matter Roll-in, Crack, Scabs.
But because defects of "Holes, Crack, Mixed Material, Blisters" influence product use badly, they are defined as key defects.

As the versatility of Rykalin series mathematical models, carbon steel, stainless steel, titanium and other different metal materials' welding heat cycle curve can adopt these methods, the methods have great practicality
As for thin-sheet material, we could choose Hannerz, Rykalin2-D, Rosenthal mathematical model.
While the thick-sheet material, we should choose Rykalin3-D mathematical model.

Traditional river side-slope protection technologies are tend to emphasize the river flood control, water diversion, drainage, water storage, shipping, etc., so the side-slope protecting works are usually constructed by use of rigid hard materials such as slurry masonry or concrete.
Therefore, neither of the methods (that is, to use rigid material or decrease slope coefficient) is ideal.
Therefore, the eco-engineering measures which take plant as main engineering material have a good application prospect.

Introduction Laser direct metal deposition (DMD) is more and more envisaged for rapid freeform fabrication of fully dense or controlled porosity metallic materials, directly starting from computer-aided design drawings.
Additional investigations on 316L stainless steel have also been carried out to identify the material contribution.
A helicoïdal powder nozzle was used, where the powder material (45 µm -75 µm average grain size) is delivered coaxially with the laser beam, resulting in a dp ≈ 2 mm powder focus diameter, and with average mass feed rates Dm in the 1 g/min to 3 g/min regime.
Future investigations will consider systematically the correspondence between melt-pool volumes and aspect ratios, and resulting surface topographies, on Ti6Al4V and 316L steel, in order to (1) propose a material-dependent phenomenological model, and, in a second step (2) to be able to predict analytically surface finish.
