Using the information given below draw and label a flowchart of the processes involved in production of phthalic anhydride. Use boxes and/or other symbols to represent process units and lines with arrows to represent inputs and outputs. Indicate the process conditions. Phthalic anhydride (PA) is produced via partial oxidation of o-xylene using oxygen. The feed to the plant is o-xylene and air. Air is compressed to approximately 2 bar in a centrifugal compressor and heated to 360°C using high-pressure steam in a heat exchanger. The o-xylene feed is passed through a pump to increase its pressure to 2 bar and subsequently heated and vaporized in heat exchanger. These streams are then mixed. The combined o-xylene and air stream enters a multitubular fixed-bed catalytic reactor. In the reactor, the o-xylene undergoes oxidation reactions to produce the desired product of PA, byproduct maleic anhydride (MA) and products of combustion. All these reactions are highly exothermic, and the temperature of the reactor is controlled by heat exchange with a stream of cooling medium that flows concurrently through the shell-side of the reactor.Using the information given below draw and label a flowchart of the processes involved in production of phthalic anhydride.

Essay Topic: Using specific examples of cultural productions from three cultures we have studied -Sumerians, Archaic Greeks (800-480 BCE), Classical Greeks (480-323 BCE)- explain how cultural values and ideals are reflected in the creation and style of cultural productions.  For each culture you must discuss the literature AND one other cultural production of your choice (ex: sculpture, architecture, pottery).  In discussing the literature, you are expected to examine the primary sources we have read for class (The Epic of Gilgamesh, The Iliad, and the works of Plato) and should utilize minimal plot summary.


Failure to meet the following requirements may result in the loss of points:


  • Essays must follow a 5-paragraph format and have an introduction, thesis statement that argues a point, a body of evidence, and a conclusion. All essays must use evidence taken from the text and class, citing important names and dates when necessary. If you are unfamiliar with the five paragraph format follow this link.
  • The text book and announcements should be your only source of information for this assignment.  Outside materials should not be used in the crafting of the paper.
  • Use your own words, but quote or cite the text as you need.  If you must quote, use no more than one short quote per paragraph.
  • Failure to apply adequate or consistent MLA citation will result in point penalties.  Simple MLA style should be used for all citations.
  • Papers should be between 900-1200 words. Failure to reach the word minimum will result in point penalties.  Exceeding the word maximum by 30 words will result in point penalties.
  • Clear and concise prose is essential to the written form and will be taken into account in grading.

  • Papers should illustrate the student

An automated sphygmomanometer tightens around a patient’s arm at a pressure of 250 mmHg, and gradually relieves pressure at a rate of 12 mmHg/sec. A microphone in the cuff records the onset of Korotkoff sounds after 9.6 seconds, and the sounds end after 16.5 seconds.
(a) What are the systolic and diastolic blood pressure values?
(b) Determine for each pressure value, whether it is high, low, or normal. If you find some values are abnormal, suggest a possible cause for the abnormalities. Cite any sources you used.
