Screen printing is a printing technique whereby a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed.
Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Ink is forced into the mesh openings by the fill blade or squeegee and by wetting the substrate, transferred onto the printing surface during the squeegee stroke. As the screen rebounds away from the substrate the ink remains on the substrate. It is also known as silk-screen, screen, serigraphy, and serigraph printing. One color is printed at a time, so several screens can be used to produce a multicoloured image or design.
Specialist frequently refers to an expert in a profession. It can also mean:
The first Sabre was a former knife thrower named Paul Richarde until he was selected by Modred to oppose Black Knight. Paul Richarde was given an armor, an animated gargoyle. and Mordred's Ebony Dagger (the weapon with which Mordred had killed the first Black Knight). He was defeated by Black Knight after his horse Aragorn kicked the dagger from Le Sabre's hand.
The second Sabre is a mutant super villain. His first appearance was in X-Men #106. Young and reckless, Sabre was chosen by Mystique to join her new Brotherhood of Mutants, though never actually participated in any missions. He had the mutant ability of super speed, and took the name of the deceased Super Sabre. It is unknown if he continues to serve Mystique behind the scenes, or if he even retains his powers after Decimation. Hyper-accelerated metabolism augments his natural speed, reflexes, coordination, endurance, and the healing properties of his body.
The specialist degree (Russian: специалист) was the only first degree in the former Soviet Union. It was traditionally inherited from the Engineering education of Russian empire, and currently is being phased out by the bakalavr's (Bachelor's) - magistr's (Master's) degrees.
In the early 1990s bakalavr (Bachelor's) and magistr (Master's) degrees were introduced in all countries of the Commonwealth of Independent States, except in Turkmenistan. However, the specialist degree remains the most often granted degree in Belarus, Kazakhstan, Russia, Tajikistan and Ukraine to this day. The specialist degrees in Armenia, Azerbaijan, Georgia, Kyrgyzstan, Moldova, Turkmenistan and Uzbekistan were renamed to diplom degrees. A similar degree in the German-speaking countries is called the Diplom degree. According to Russian federal educational legislation, the specialist degree requires at least five years of full-time study (whereas bachelor's and master's degrees require at least four and two years respectively).
