Background of the study Tuberculosis has reemerged as the leading cause of morbidity and mortality in Kenya Infection rate is highest between 15-44 years with a nine fold increase since early 90’s due to the HIV/AIDS pandemic. The HIV infected have an increased incidence with a majority presenting with smear negative PTB Hypothesis Chest x-ray in itself is not an effective method of diagnosing smear negative pulmonary tuberculosis in H.I.V positive patients Broad Objective To assess the

X-ray 1 is a left lateral view of the lumbosacral spine taken with the patient in weight bearing or standing. This lateral view is produced with a round cone to better visualize the lumbosacral junction. X-ray 1b is the left lateral view of the lumbosacral spine with the patient positioned in sidelying. Bony Pathology: The bone density appears uniform within the vertebrae and surrounding bone. Osteophyte formation and lipping are noted at the margins of the vertebrae‚ most significant in L3‚ L4

Extracting sliver from used X-ray films using new techniques SUMMARY Silver is one of the precious metals that exists as silver halides and dark silver in X-ray films therefore recycling it is essential. I decided to carry out my research in the field of extracting silver from used X-ray films using new technique that dose not deplete ant metallic resources or energy resources meaning that the project must be environmentally friendly. My research consists of two parts‚ part one which is carrying

Mr. Green will be getting an x-ray on his femur to see if he has a break. While he was in his garage getting Christmas decorations down‚ he fell off his ladder. First‚ I will let him know that this is a simple procedure‚ and he will need to have an x-ray so the physician can take a closer look at the break. “Proper preparation is essential for the best radiographic results. Having to repeat the procedure because of inadequate preparation results in increased patient anxiety‚ time‚ expense‚ and

use of X-Rays in Modern Dentistry Dentistry is increasingly becoming a major part of people lives in today’s society‚ being taken for granted and often little thought about. As technologies advance treatment becomes cheaper‚ quicker‚ and the outcome becomes more aesthetically pleasing and longer lasting. As braces‚ dentures‚ crowns‚ procedures and techniques change and improve at an alarming rate‚ one aspect has remained the same for a longer period of time. This is the use of X-Rays. X-Rays have

with higher resolution‚ faster‚ lower-dose screen-film combinations‚ have contributed to earlier cancer detection in women. Dr. Wilhelm Conrad Roentgen discovered x-rays while working with a Crookes tube in his laboratory on November 8‚ 1895. Eighteen years later mammography got its rudimentary beginnings due to these ionizing x-rays. In 1913‚ Berlin Albert Soloman‚ a German surgeon‚ was among the first to discover that breast cancer could be radiographed. In a 1927 medical textbook the first instance

XRD – X-Ray Diffraction X-ray diffraction (XRD) is a powerful non-destructive technique for characterizing crystalline materials. It provides information on structures‚ phases‚ preferred crystal orientations (texture)‚ and other structural parameters‚ such as average grain size‚ crystallinity‚ strain‚ and crystal defects. X-ray diffraction peaks are produced by constructive interference of a monochromatic beam of X-rays scattered at specific angles from each set of lattice planes in a sample. The

X-rays were first discovered through a mistake. In 1895‚ a German physicist named Wilhelm Roentgen made the discovery while doing an experiment that involved electron beams in a gas discharge tube. Although he is not the first one to observe X-ray effects‚ he is given credit as the discoverer of the X-ray‚ despite the amount of earlier researchers. Medical professionals use X-rays to spot fractures‚ infections and tumors. There are different types of X-rays like CAT scan and fluoroscopy‚ but the
