Radiologic Technology is an interactive career in which X-ray machines utilize ionizing radiation to take images of patients’ bones throughout their bodies that may or may not be broken. The image is then sent to a Radiologist who analyzes and diagnoses the image and sends the results to the doctor. As a technologist you must be able to effectively operate the X-ray machines, correctly position patients, interact with them to make them feel comfortable while always staying as protected as…
The experiment investigates a GM tube and a GM counter and the relationships of radiation. The experiment uses a GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the…
dependent changes in the optical properties of the protein. This could be due to either the refractive index changes in the sample or possible dimerization/aggregation. This change should be considered when performing the fluorescence analysis. This implies that the fluorescence titrations up to 200μM are well behaved i.e. linear. The experiment in figure 2 shows that when the samples are run in a 0.1 cm cuvette and not in a 1 cm one, and their corresponding absorbance multiplied by 10 to put…
this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…
techniques given below. • Powder X-ray diffraction(PXRD) • Ultraviolet –Visible spectrometry(UV) • Scanning electron microscopy(SEM) • Energy dispersive X-ray spectroscopy(EDS) 1.8.1 Powder XRD analysis (PXRD) The structural information of the prepared samples is examined through powder X-ray diffraction. X-ray crystallography is a tool, which is used to identify the crystal structure of a system. By measuring the angles and intensities of the diffraction pattern, we…
The CT scanner Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are…
Lab 4: Crystal Structure and X-Ray Diffraction of Materials Introduction The purpose of this experiment is to study the relationship between the geometry of a sample and its diffraction patterns through an exploration of reciprocal space. In this experiment, both a single crystal piece of Si with a (004) reflection plane and a Si powder sample are scanned, as well as the peaks the locations of the diffraction peaks on the single crystal. The collected data is then analyzed to determine the…
TITLE: QUALITATIVE PHASE IDENTIFICATION & CRYSTAL STRUSTURE ANALYSIS OF ISONICOTINAMIDE POLYMORPHS. INTRODUCTION The science of crystallography is important in stability studies and determination of solid state molecule or particles. Isonicotinamide (pyridine -4- carboxamide) is the amide form of isonicotinic acid which exists as different polymorphs. Isonicotinamide finds extensive use in the pharmaceutical industry because of its good anti-tubercular, anti-bacterial, anti-pyretic and…
sizes were observed over multiple trials, and then the averages were compared to see if there was any difference between the mutant and WT. Furthermore, the two strains of Tetrahymena were stained with mCherry fluorescence, so that the oral grooves could be examined and compared under fluorescence microscopy. This experiment was designed to eliminate as much bias as possible by replicating the experiment over 4 trials, one by each member of the team working on this project. Since this Sfr13…
Radiology Research paper Scientist Wilhelm Roentgen accidentally discovered X-rays while studying the pathway of electricity. He realized this when he saw objects in the picture that wouldn’t usually appear in a normal photograph. Roentgen’s discovery was soon after, advanced further by Dr. Harvey Cushing in the first diagnostic clinical X-ray. 1902 was the first year they were used for ground breaking brain surgery, he used the technology to view and assist removing malignant and non-malignant…
