Augmentative and Alternative Communication, or AAC, is a major method of treatment for aphasia. This treatment allows the individual with aphasia to be a conversation partner and engage in communication that may have been limited before treatment. It is crucial with aphasia to begin fostering communication through AAC very early on in the treatment process. These AAC devices can include low-technology device or high-technology devices (Fried-Oken, Beukelman, & Hux, 2011). One type of AAC…
VOXEL BASED MORPHOMETRY: APPROACH FOR ASSESSMENT OF ALZHEIMER'S DISEASE USING ADNI DATA
• MRI PROCESSING
• VOXEL BASED MORPHOMETRY
o What is a voxel
o VBM methodology
o Statistical Analysis
The curiosity to look into the brain has always interested researchers. As the brain grows in size its functioning improves and at a later age (old age) it also deteriotes.MRI…
Screening and Early Detection for Colorectal Cancer
Early detection and the removal of precancerous polyps can prevent the development of more than 50% of colorectal cancers (American College of Gastroenterology 2015).
Screening is an integral part of preventing colorectal cancer. Screening is the process of looking for cancer or precancer in individuals who do not have symptoms of the disease. Physicians recommend that average-risk individuals get screened every 10 years starting at age 50.…
to preventing blackouts and providing a stable electrical grid. Scientists around the world are contributing time and money in their tireless pursuit of the development of fusion and along the way have made many major breakthroughs in other science fields. In the next ten years hopefully humans can finally find an alternative solution to meet our energy needs that is clean, renewable and…
"Opposites attract and likes repel"-a fundamental scientific principle that has been applied not only to fields such as chemistry, magnetics, and physics, but to other aspects of life including relationships. This principle is evident in Mary Shelley's 1818 novel, Frankenstein. There are several attributes that differentiate Victor Frankenstein and his Creature including their creation, education, relationships, and trials, which could make one think that the two characters could end up being…
crash because the gas gets into the air after explosions in the ocean and it might cause explosions in the air (“14 Popular Bermuda Triangle Theories”). Christopher Columbus recorded that he saw strange variations on his compass which supports the magnetic and absolute North difference in the area (Rudolph). Large waves have formed In the Triangle because of the Sargasso Sea, it has ocean currents but no shore. Also, spectators ever recorded waterspouts that have occurred in the area could be…
mass., it 's the ideal atmosphere to live in because it produces oxygen and weather that aids life to flourish. There is one more additional layer that is actually vertical and overlaps the exosphere, thermosphere ,mesosphere and the earth 's magnetic field that causes the gasses within this portion of the atmosphere to become highly excited by the energy emitted from the sun, charging its…
Titanium is a low-density element (has 60% density of steel), that be able to be highly modified by alloying and distortion processing. Titanium is non magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness,…
AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material.
1. Extraction process.
2. Melting process.
3. Storage process.
Extraction of Titanium by Kroll process:
First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process:
Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…
During the execution of an application, a fault may take place due to various reasons, such as hardware failures, software errors and electro-magnetic effects. Therefore, fault-tolerance is an inherent requirement of systems when accurate results are needed even in the occurrence of faults. In the fault-tolerance area, redundancy is employed to mask or otherwise work around these faults, in this…
