ACTIVITY 5 Exploring Various Breathing Patterns You will establish the baseline respiratory values in the first part of this experiment. 1. If the grid in the data control unit is not empty, click Clear Table to discard all previous data. 2. Adjust the radius of the airways to 5.00 mm by clicking the appropriate button next to the Radius window. Now, read through steps 3–5 before attempting to execute them. 3. Click Start, and notice that it changes to Stop to allow you to stop the respiration. Watch the simulated lungs begin to breathe as a result of the external mechanical forces supplied by the pump below the bell jar. Simultaneously, the oscilloscope will display a tracing of the tidal volume for each breath. 4. After 2 seconds, click†¦show more content†¦Note that when a measure button is selected, two things happen simultaneously: (1) a bracket appears on the spirogram to indicate where that measurement originates on the spirogram and (2) the value in milliliters appears in the data table. Also note that when the FEV1 measure button is selected, the final column labeled FEV1/FVC will be automatically calculated and appear in the data table. The calculation is (FEV1/FVC) _ 100%, and the result will appear as a percentage in the data table. What do you think is the clinical importance of the FVC and FEV1 values? Why do you think the ratio of these two values is important to the clinician when diagnosing respiratory diseases? _______ FEV1/FVC _ 100% _ ______________________ Emphysema Breathing In a person with emphysema, there is a significant loss of intrinsic elastic recoil in the lung tissue. This loss of elastic recoil occurs as the disease destroys the walls of the alveoli. Airway resistance is also increased as the lung tissue in general becomes more flimsy and exerts less mechanical tethering on the surrounding airways. Thus the lung becomes overly compliant and expands easily. Conversely, a great effort is required to exhale as the lungs can no longer passively recoil and deflate. Anoticeable and exhausting muscular effort is required for each exhalation. Thus a person with emphysema exhales slowly. 1. Using this information, predict what lung values will change in the spirogram when the patient with

The Slice Of A Knife - 1296 Words

The Slice of a Knife He didn’t look that dead. Apart from the river of blood rushing out the gaping neck wound, he looked pretty much the same as he did a few minutes before. His hand was still clasped around his bottle of beer and face was still frozen in a permanent gaze of boredom. The only thing different about James’s face was the single tear that rolled down his cheek and hung on the cliff of his chin amongst his stubble. As it fell from his face, his body smashed forward into the wooden table. And in that moment I felt completely alone. James was the only reason I was there with the oudious group of so-called ‘friends’. Only a few moments before we had been having a wonderful time, drinking wine out of chipped coffee mugs and reminiscing about ‘the good old days’. Then in a beat of a heart, the lights gave out. Exploded glass cascaded from the ceiling and the sudden fright caused everyone to panic. There were a few minutes of clattering in the murky darkness before Bill switched his massive solar-powered lamp he (ever so conveniently) had with him. So typical of Bill, why had he even brought a lamp in the first place, particularly a solar powered one. He had also carried an excessive amount of electronic devices that he immediately proceeded to plug in as soon as he got the chance, perhaps thats why the power gave out. James was murdered in that dark but did Bill have reason to see James dead? With James out of the way he would be in total control of their company,Show MoreRelatedEssay about Hand Soap versus Hand Sanitizer1203 Words   |  5 Pagesmaterials needed for this experiment.

Portrait of Mehmet II Free Essays

The most important aspect one has to consider when looking at the Portrait of Mehmet II is the historical context which represents the key to understanding the work of art in question. It is highly relevant to shift one’s focus from the artistic achievement to the historical background of the last two decades of the 15th century, i.e. We will write a custom essay sample on Portrait of Mehmet II or any similar topic only for you Order Now the time when the portrait was painted. The 1453 conquest of Constantinople was a cataclysm felt throughout the entire Western world. The Ottoman Empire, now a force everyone feared, had not been assessed at its true power. The giant empire was born in Central Anatolia, but soon expanded and incorporated a myriad of territories and ethnic groups, such as the Greek in Western Anatolia, Arab, Armenian and Kurdish on the shores of the Mediterranean (Melikian, Venetians and Turks: A Mutual Curiosity). The Venetians strongly opposed the expansion of the Ottoman Empire, which threatened the parts of Greece they controlled. Moreover, the demolished church of the Holy Apostles had been the model for their most famous monument, the 11th century masterpiece adorning the heart of Venice, the church of San Marco. Nonetheless, the advance and growth of the Empire continued. The peace agreement of 1479 saw Venice giving up important parts of the Greek territories they controlled, as well as the Albanian city of Shkà ¶der (Scutari in Italian) (Melikian, Venetians and Turks: A Mutual Curiosity). The peace agreement signed by the Ottoman Empire and the Venetian Republic stipulated that â€Å"a good painter† (Metropolitan Museum of Art, http://www.metmuseum.org/toah/hd/cedr/hd_cedr.htm) from Venice be sent to the Sultan’s court to paint a portrait that would be to Mehmet’s liking. This is why, one year later, after careful consideration, the Venetian doges dispatched their best portraitist, Gentile Bellini to Constantinople. A mixture of the East and the West, the Portrait of Mehmet II is an authentic instance of the successful meeting of two very different approaches to art. What is truly striking about the portrait is the warm Venetian light surrounding the face of the Sultan, which both lightens up his features, making the painting itself incredibly clear, and also gives the character a certain duality. This ruler-man duality illustrates Mehmet as a simple man, thanks to the clarity of the facial features, but also as an emblem, a precious figure in the history of humanity. This lighting technique is perhaps the best example of how the Renaissance naturalist trend and Oriental art are intertwined in this particular 15th century masterpiece. As far as facial features, the viewer cannot help but notice the nasal structure of the Sultan, an aquiline nose suggesting wisdom and courage, traits of character that are also symbolized by the heavy beard, an ancient symbol of masculinity and maturity. The contrast between the face of the Sultan and the edges of the painting, dominated by dark colors and a reduced amount of light, is supported by the choice of primary colors as far as the clothing of Mehmet is concerned. The two subtle shades of red that are to be identified in his robe, combined with the large white turban, a symbol of his greatness as a ruler, create a chromatic contrast that pleases the eye and highlights the face of the Sultan. Mehmet II, the Conqueror, seized Constantinople in 1453 putting an end to the Eastern-Christian world of Byzantium. Considered by many historians as â€Å"the late-medieval world’s most powerful man† (Jones), Mehmet II was only 19 when he followed his father at the throne of the Ottoman Empire. Because of his young age, the Western world disregarded him and severely underestimated his strength and determination. Nevertheless, in 1453 he summoned his ministers in Adrianople where he expressed his desire to conquer Byzantium (Mehmet II, http://www.theottomans.org/english/family/mehmet2.asp). After a two-month siege, and the refusal of his opponents to surrender, Mehmet II captured Constantinople. Following his great success, he entered the city accompanied by his chef ministers and rode to St. Sophia. He then kneeled in front of the church and sprinkled a handful of earth over his turban. This gesture would be known as the first step towards the conversion of St. Sophia into the most important mosque of the city (Mehmet II, http://www.theottomans.org/english/family/mehmet2.asp). As far as trade was concerned, the Republic of Venice was the most important player in the Near East, maintaining their good reputation in the area thanks to skilled diplomatic initiatives which were being unrolled on two levels. At the highest level, thanks to their ambassadors, the doges were involved in trade negotiations with Muslim sultans and other officials. These high-rank meetings followed strict proceedings, such as gift exchange. Relevant examples of this practice is the gift of the Venetian envoy Benedetto Sanudo to an emir consisting of fine cloth and Parmesan cheese, as well as the envoy’s present to the Sultan in Cairo – furs, cheese and luxurious textiles. In return, the representatives of the Venetian Republic received gifts ranging from watermelons and chickens, to Chinese porcelain. At a lower level, the Venetian Republic named consuls in the Near East. These were members of the Venetian nobility, elected by the Senate on two-year mandates and in charge of paying tribute to local officials (Metropolitan Museum of Art, http://www.metmuseum.org/toah/hd/cedr/hd_cedr.htm). Despite attempts from the papacy to prohibit trade between Venice and the Near East, the ties between the two parties could not be severed. On the contrary, Venetian officials always fought against such interdictions, and even defied the Pope in order to maintain the east-west trade exchanges (Metropolitan Museum of Art, http://www.metmuseum.org/toah/hd/cedr/hd_cedr.htm). The Portrait of Mehmet II is significant proof of the lengths that the Venetian state went to in order to ensure peace and good trading relations with the Sultan.
