Vacuum tube

down according to the patient’s height or during the patient transfer from the gurney to the radiographic table. The table should be in floating form so that the patients on the table is easy to be align with the tube and film (Proctor and Adams, 2014). The table must built with foot controller so that it is easy for the radiographer to control the movement of the table without use much energy. Additionally, the…

methods of production of CNTs, for instance carbon nanotubes produced by chemical vapour deposition is having a carbon content of 83 wt.% (95 vol.%) and a specific surface area equal to 790 m2/g[3]. Pre-treatment of obtained CNTs, different tube diameters and tube lengths, inner spacing, different process of purification of CNTs. This article studies the parameters…

In a cell there are many organelles to help keep the cell functioning. In the cell you could have a cell wall, cell membrane, ribosomes, cytoplasm, flagella, cilia, nucleus, nuclear membrane, nucleolus, chloroplast, Golgi apparatus, lysosomes, mitochondria, plastid, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, and a vesicle. Everyday items can represent many of the organelles. One example of this is by looking at a house. In a house you have a fence. The fence in your…

what goes on in the upper earth so they started making detailed instruments. Thermometer A thermometer is an instrument that measures temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is. Some of the first thermometers…

Neon is one of the world’s rare and most expensive elements. I chose Neon because of it's uniqueness. In 1898, William Ramsay and Morris Travers at University College London isolated krypton gas by evaporating liquid argon. They had been expecting to find a lighter gas which would fit a niche above argon in the periodic table of the elements. They then repeated their experiment, that time allowing solid argon to evaporate at a slow pace under reduced pressure and collected the gas which came off…

In this day and age people fly through gears pushing everything to its limit. With that being said we need the best ways to bring our vehicles to a stop. Over the years our braking systems have been improved over and over. In the said old days we used “spoon” brakes. Today we use ABS, air brakes, drum brakes, disk brakes, and they are even coming out with full contact disc brakes. But those are still a work in progress and it will be a few years until we see those on any type of vehicle. So in…

The spiral shape of the cyclotron allows for a much longer acceleration path than a straight line accelerator. The cyclotron body consists of electrodes (they are called dees because they look like the letter D) in the vacuum chamber. This chamber is flat and sits in a narrow gap between poles of a large magnet creating a perpendicular magnetic field. A high frequency voltage is applied across the electrodes as a surge of charged particles is fed into the centre of the…

About 1.21 million abortions are performed per year, and 125,000 abortions per day. Thats a lot of precious lives lost. The procedures can be very disturbing. some women may think it’s the best choice for them but the child could have a better life if she chose to have the baby and put it up for adoption instead of “killing” the helpless child. In my opinion abortion should be banned in the united states. There are many different types of abortions, but no matter how the surgery is…

One type of procedure is the manual vacuum, this is completed early on in the pregnancy where an elongated, thin tube is inserted into the uterus while a large needle is attached to the tube and the fetus is suctioned out. The most common procedure is the suction curettage. Due to the fetus being larger the mother must go under anesthesia and then the doctor stretches open the cervix using metal rods and then inserts a hard plastic tube that connects to a suction machine into the uterus…

ensure homogenous solution, the salt solution was poured in slowly. This was continued for thirty minutes and then sodium acetate was used to neutralize the solution (pH 5-6) and this took around thirty minutes; after this was over, the product was vacuum filtered and rinsed with slightly cold water. The product, observed qualitatively, was bright orange-red color. The reason for this color and not the azo-violet color presumed, was due to absorption of wavelengths. In acidic environment, the…
