Materials Used In Pacemakers Image result for what is a pacemakerThe way how a pacemaker is constructed is very crucial to how it would function later. The materials used to construct pacemakers must be non-toxic‚ sterilisable and able to function in the environmental conditions of the body. Some of the fundamental parts of the pacemaker such as the casing‚ battery‚ circuitry and the leads are all made with biocompatible materials or non-toxic materials. Usually‚ the casing along with the lead is

1.0 INTRODUCTION The basic idea of the Multi-slice Computed Tomography (MSCT) is to widen the x-ray source with several detectors in rows so that the data can be gathered of more than a slice a time thus reduces the time of scanning. From the first establishment till this day‚ the MSCT systems had change in so many aspects. The advancements of the systems are to fulfill the medical needs and had brings a lot of convenience to the clinical fields. By producing the 3D image‚ the MSCT give a great

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

DCpolarity samples consisted of martensitic with some bainitic structure in the weld metal and bainitic structure in the HAZ. The undesired microstructure in the weld metal using this polarity resulted from the heat difference between the cathode and the anode. The DC+ polarity samples were observed to have bainitic structure in the weld metal and a mixture of bainite and ferrite was observed in the HAZ. The AC polarity samples were noticed to have more complex microstructures compared with the other two

Figure 1 LED Matrix Connected to the PPI Ports 2 The dot matrix terminals are controlled using all three ports on an 82C55 peripheral programmable interface. Ports A and B are used to drive the cathode of the LEDs‚ while Port-C would drive the anodes terminals. Port-A drives the red LEDs while port-B drives the green LEDs. If the two LEDs with the same coordinates are enabled then the outcome will be an orange dot. Ports A and B select the rows while Port-C select the columns as shown below:
