Cathode ray tube is used for producing images‚ when an electron beam hits the surface made out of a phosphorescent‚ and the cathode ray tube is basically a vacuum tube. An example of a cathode ray tube is a computer desktop and the picture tubes in television are similar to the cathode ray tube in television. There are numerous components of cathode ray tube‚ which are the Electron gun‚ Anodes‚ Coil‚ Phosphor-coated screen‚ electronic beam and the spot through which the beam passes through. In a

Nursing Care of the T-Tube after Cholecystectomy Also called a biliary draining tube. May be placed in the common bile duct after cholecystectomy or choledochostomy. The tube facilitates biliary drainage during healing. The surgeon inserts the short end (crossbar) into the common bile duct and draws the long end through an incision in the skin. The tube is then connected to a closed gravity drainage system. Post-operatively it remains in place between 7 to 14 days. Equipment Graduated collection

Carbon nanotube 1 Carbon nanotube Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with [1] length-to-diameter ratio of up to 132‚000‚000:1‚ significantly larger than for any other material. These cylindrical carbon molecules have unusual properties‚ which are valuable for nanotechnology‚ electronics‚ optics and other fields of materials science and technology. In particular‚ owing to their extraordinary thermal conductivity

Recently a scientist by the name of Mark Post helped create a “test tube” beef burger. The burger was grown in a solution of nutrients and cost about 330‚000 dollars to make. The burger was created by taking muscle cells from a cow and growing them into tissue. The meat had to be dyed to make it look like real beef. The meat contains no fat and is disease free. The meat was made in the Netherlands at Maastricht University. It was served to two volunteers and was flavored with egg powder and bread

There are two devices that are most commonly used and each device has specific indications and contraindication. 2 Research question This study was done to answer the following question: Are licensed practitioner’s beliefs about airways (oral ET-tube and LMA) consistent with the current printed information and do they report using the airways in a similar manner? To answer this question‚ we first needed to know what practices the current published studies have suggested will have better out-comes

2.MATERIALS and METHODS 2.1. Nature of Reactants 2.1.1 We placed 3mL of 3 M HCl into each of 3 seperate test tubes. Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and

GREAT DISCOVERIES CHANGE LIVES Do you like watching television? I love it. I do not know what would I do if televisions did not exist. It is interesting‚ in several years‚ they have become a huge part of our lives‚ our indispensables. J.J. Thomson was inspired by some scientists and he provided us the opportunity of having televisions in our lives. Also other scientists improved his thoughts and experiments which leaded to the invention of the television afterwards. It is not that simple of course

Insertion and amplification of EGFP protein into pET41a(+) Plasmid Introduction The overall purpose of the experiments conducted is to test the creation of recombinant plasmid using recombinant DNA technology. The research of recombinant DNA began with the use of E.Coli (Escherichia coli)‚ a common bacteria found in the intestines of warm-blooded or- ganisms (5). Scientists worked together and generated a way‚ from cloning and using recombi- nant research‚ to achieve recombinant DNA
