Eustachian tube

suffered at least one episode of acute otitis media” (Montague & Hussain, 2007). This fits into my area of clinical practice as an ENT nurse we evaluate patients who are referred for recurrent ear infections to determine if surgical intervention is recommended in the way of pressure equalization tubes, which act as a bypass to the eustachian tube. The pathophysiology of this condition is characterized by some form of intrinsic or extrinsic factor resulting in eustachian tube dysfunction from a classic understanding of the disease. However, some studies point to the initial inflammation occurring in the middle ear and the progressing…

Middle ear infections are caused by bacteria behind the eardrum causing it to become inflamed causing pain in the ear. It’s more common in children than adults for the reason of the Eustachian tube, which is tube that connects from the middle ear to the pharynx, to be shorter in children than adults making the bacteria easier to get to the middle ear. Other causes of getting a middle ear infection is exposure to secondhand smoking, bottle feeding, daycare centers or if your child has a cold or…

Misophonia is a brain disorder in which a trigger sound can send a person into extensive irritation or —in extreme cases—even rage. Symptoms typically present themselves in children from the ages of 9 to 13, but it can show both earlier and later in life. Affecting millions of people in the world, misophonia is extremely common and nearly undetectable in most cases. People who have very mild cases often times never go diagnosed; however, it does not usually have a large impact on their everyday…

dialysis tubing was used to mimic the selectively permeable membrane to show what osmosis does when placed in different solutes. We filled dialysis tubes fill with different percentages of solute and placed them in beakers full of a different solute. Through this experiment, I saw what happens when the solution becomes hypertonic, hypotonic, and isotonic. My hypothesis was that bag A would shrink because the water would leave the bag to go to the higher concentration. Bag B would stay the…

I chose to do my project on the Pyro board which is an adaptation of the Rubens tube. The Pyro board uses fire to demonstrate sound waves. I chose this as my project because I find music and fire fascinating. Having them interact to demonstrate the physics side of sound helped me understand all the different aspects that can effect sound waves and alter the way we interpret them. Before I started to build my Pyro board I did research on how they worked why they worked and why the flames reacted…

Introduction This case study report is to outline the process of planning an activity in science understanding physical science for a 5 year old child with the expectation of learning the concept of motion, inertia, force, velocity, acceleration and gravity by using balls, blocks and tubes. The report will also outline the pedagogy approach adopted by educators to ascertain that the child will engage in a physical science activity, which will improve the child’s skills of problem solving,…

Personal Energy and Material of Toothpaste The cycle of energy that gets put into the simple product of a tube of toothpaste is a rather lengthy one. Most people simply think of the raw materials that are put into the toothpaste, but what about the tube itself? Most people just consider the resources that are put into the paste, but what about the energy used to transport those resources or to mix them together. Perhaps one has considered the tube and the energy that was put into making it, but…

There seemed to be an error in the experiment conducted, which will be later discussed. In order to show what should have happened, the absolute value was taken of the answers using the numbers that were read from the spectrophotometer. For example, in the PTU test tube the amount after ten minutes subtracted from the amount after twenty minutes gave the answer of -0.023, but instead, and instructed by our teacher, we took the absolute value and said it was 0.023. The formula used to display…

transformation solution to into two separate tubes. Next, we used a sterile loop to transfer two to four larger bacteria colonies from an E.coli plate into each of the two tubes. The bacteria was observed under UV light to make initial observations. We pipetted 10 ul of pGLO plasmid (0.08 ug/ul) into one of the tubes. Both tubes were incubated on ice for ten minutes. After ten minutes of incubation, the tubes were heat shocked at 42°C for exactly 50 seconds and then returned to ice. After two…

In these camps “the death rates were so high, from malnutrition, typhus and exhaustion that the disposal of corpses became a serious problem.” (THE CAMPS) The treatment in transporting and caring for the victims is probably one of the main factors in the dehumanization of people during Holocaust. The victims were treated inferior simply because of their nationality. The Nazi’s made it a point to degrade these people in every way possible by taking away their rights and free will.…
