waste of material. The spindle runs in precision bearings and is fitted with some means of attaching work holding devices such as chucks or faceplates. This end of the spindle usually also has an included taper‚ frequently a Morse taper‚ to allow the insertion of hollow tubular (Morse standard) tapers to reduce the size of the tapered hole‚ and permit use of centres. On older machines‚ the spindle was directly driven by a flat belt pulley with lower speeds available by manipulating the bull gear. Later

John Donne "The Apparition" In John Donne’s poem‚ "The Apparition‚" the title tells us that the poem is about a person having an epiphany. We know this because the word "apparition‚" means "to become visible" or "an epiphany." In the opening lines of the poem‚ the speaker addresses his listener as a "murdresse." He then goes on to tell her that when she "thinkst" she is "free from all solicitation from" him‚ his "ghost will come to" her bed. This tells us that the speaker is a rejected

are done mechanically with a tattoo gun‚ which is a small motor that moves the needle up and down to penetrate the skin. A long taper needle will deposit fine grain pigments deeper into skin with less risk of skin damage. Long tapered needle work well for total saturation and they also help feather pigment into the skin for softer‚ smoother effects. The shorter the taper‚ the greater the risk that you will push the needles a few thousands of an inch too deep into the dermis cells‚ and the outermost

placement of a large piercing‚ to combine two existing piercings into one‚ and to achieve a higher gauge piercing when scar tissue or the tissue is too thin to stretch (“Stretching (body piercing)”). The scalpel and taper method takes place after a piercing or a scalpelling. A large taper is inserted directly after the two allowing the skin to be stretched to large diameters instantly (“Stretching (body piercing)”). This method can be extremely painful. It is discouraged because it can cause the

Hence‚ quantitative easing has been quite good for increasing employment and boosting the household wealth in US (The Economist

power and standoff distance on the quality of the machined surface using Carbon dioxide (CO2) laser beam on 3 mm thick mild steel sheets. The quality of cut is assessed in terms of response parameters such as upper kerf width‚ lower kerf width‚ taper of the cut surface and surface roughness. Design of experiments was implemented by using a full factorial design. The effect of the process parameters on response have been shown by means of main effect plots developed using statistical software

The Chinese use chopsticks as easily and as naturally as Europeans use forks. They are like an extension of a man’s fingers‚ practical adaptations that evolved from the days when man indeed ate with his fingers. There are different styles of chopsticks. The Chinese variety is blunt on the "eating end‚"‚ while the Japanese prefer those with pointed tips. There are even short lengths for children for use. Chopsticks are made of many materials - ivory‚ plastic‚ silver‚ and even jade - but the most
