Bare-metal stent

nonsurgical procedure to treat atherosclerosis within the heart’s vessels (cite). Percutaneous coronary intervention, a balloon angioplasty procedure, involves inserting a metal wire stent within a constricted coronary artery. Using a balloon catheter with guided x-ray imaging, the stent is implanted as the balloon simultaneously inflates. The inflation of the balloon breaks up atherosclerotic…

without his parent he grow up learning from Grandpa and most importantly from Grandma. Grandma was a very important part of Little Tree’s education because she teach him how to be kind, compassion, and giver but most importantly how to learn and appreciate mother nature. At the beginning of the movie, when Little Tree was narrating his story, he said that his Grandma told him that if he ever found something good in life, he should always share it with whoever he found, so the good keep…

Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…

It is used in power generation, transmissionn, distribution, telecommunications etc. According to Wikipedia, around half of the copper which is mined throughout the world is used for electrical wiring and cables. It isnt however just used based on its electrical conductivity properties alone. It is chose because it has other benificial products as well. These include; high tensile strenght, ductility, corrosion resistant, low thermal expansion and is able to be soldered. So having these…

Magnesium Alloy: Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: http://www.omicsonline.org/JMSTimages/2155-9589-2-114-g001.html Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400…

2. RESEARCH ON THE STRUCTURE OF METALS AND TYPES OF BONDING. What are metals? 24% of our planet’s mass is metal. They are used as mainly because of their properties; metals are strong, ductile, have high melting points and are excellent conductors of electricity. Other properties of metals are given below: • Can be made stronger by alloys and heat treatment. • Easily machined. • Most of them are heavy. • Susceptible to corrosion. Metals can be divided into two; Ferrous and Non-ferrous. Ferrous…

The word crucible has three defintions. The first defintion is a pot which, because it can withstand great heat, is used to melt iron and other metals. The second definition is a severe test or hard trial. The third definiton is an adjective used to describe a very high grade of steel. In Arthur Miller’s play, The Crucible, John Proctor fits all three of the definitions of the word crucible. The first definition of the word crucible is a pot which, because it can withstand great heat, is used…

being almost a point and shoot club. You may completely focus on controlling the impact force. Thereby, achieving the desired distance and control thereof. − Accuracy and Forgiveness: They fall into the category of ‘game improvement clubs’. Be assured that an optimum ratio of accuracy and forgiveness comes built in. You achieve accuracy from inherent design characteristics. Which offer help in the toe and lower on the face area of the blade. The most forgiving of the lot is the JPX-900 hot…

treatment, ion-exchange, reverse osmosis, precipitation etc.) have been practiced for decades. But these techniques exhibit serious drawbacks such as high operational cost, generation of toxic metallic sludge in the case of non-selective precipitation and low efficiency in low concentrations like in the case of ion exchange and reverse osmosis. However biotechnological approaches, and more specifically biosoprtion can cover those niches due to lower cost, higher efficiency, biosorbent…
