The gastrointestinal tract and inhalation

Science

Pollution Prevention by Paul L Bishop

1) What are the molecular modifications that can be made to reduce absorption by the gastrointestinal tract and inhalation?

2) Discuss the steps involved concerning the development and implementation of a pollution prevention plan for a large three shift manufacturing operation that employs over 300 people and has multiple operating units such as shipping/receiving, administrative offices, raw/finished product storage, warehouse facilities, quality control laboratories, and manufacturing.

3) Why do firefighters recommend the use of a deluging volume of water when extinguishing an oxidizer-supported fire? What may happen to a large (i.e., 30-50lb) container of trichloro-s-triazinetrione, or calcium hypochlorite, if it is left to sit in the water and muck remaining in a building after fire fighting efforts have ended, but clean-up will not begin for several days? The assumption here is that the plastic container has been compromised in some way by the heat of the fire and possibly creating cracks in the base or sides.

4) All ammonium compounds, which contain an ammonium ion (NH4+) and a negative ion, are thermally unstable.

A. Discuss two ways that ammonium compounds decompose when they are heated. What chemical reaction is involved in the thermal decomposition of ammonium persulfate?

B. What is the most likely reason OSHA requires ammonium nitrate to be segregated for sulfur or finely divided metals? Explain your answer.

C. What is the most likely reason OSHA requires employers to protect flooring and handling areas in buildings against impregnation by ammonium nitrate and requires that the floors be constructed without open drains, traps, tunnels or pits into which molten ammonium nitrate could flow and be confined in the event of a fire?

5) U.S. companies export pesticides that have been banned or restricted in this country. Should this practice be allowed to continue? Please give a specific answer and support your rationale or logic.

6) Make a list of some food additives found in your home. Review the literature and show their ingredients and adverse effects. Cite at least two reference sources in your response.

7) List aromatic amines used in industry and discuss their toxicological effects.

Explain two renaissance paintings and renaissance sculptures

History

For your Individual Project assignment, you will compare and contrast a work of art in a specific classification (Renaissance or Gothic) appearing on a WEBSITE with a work of art in your TEXTBOOK of the same classification. You can choose either two Renaissance paintings, two Renaissance sculptures, or two Gothic Cathedrals to discuss (two works in total). You may not discuss works that you have already discussed in another assignment.

1. To begin your project, explore the following websites classifications for your individual essay.

A. Visit the following Web sites to review Renaissance art. Links to these Web sites are available through the unit Resources List, in Course Materials.

a. The Vatican Museums

b. ArtLex – Earlier Renaissance Art

c. ArtLex – Later Renaissance Art

B. Visit these Web sites for Gothic Cathedrals. Links to these Web sites are available through the unit Resources List, in Course Materials.

a. Chartres Cathedral

b. A Digital Archive of Architecture – High Gothic

c. Earthlore Gothic Dreams – Cathedral Architecture

2. Write the Individual Project (3-4 pages not including references):

a. Using the terminology and concepts you are learning for evaluating art, including materials used, style, meaning, and symbolism, and any other aesthetic issues, compare and contrast ONE of the selected works from the selected websites classification with a DIFFERENT work of art of the same classification from your TEXTBOOK . For example, compare two paintings from the Renaissance period or two gothic cathedrals. Use the following instructions to construct your paper:

b. For each of the works of art, describe and compare attributes of the works by following the guidelines below to structure your essay.

1. What is the FORM of the work?

a. Is it a two-dimensional or three-dimensional work of art?

b. What materials are used?

c. What techniques or processes are used to create the artwork?

d. What colors are used?

e. Describe the use of line, shape, texture, value, color, and balance.

2. Does the work of art have SUBJECT MATTER?

a. If so, what is literally depicted?

b. Is the work of art REPRESENTATIONAL, ABSTRACT, or NONOBJECTIVE?

3. What is the CONTENT?

a. What does it mean or represent?

b. What is the artist’s message?

c. Is symbolism used? If so, what is the meaning?

d. What is the context of the artwork?

e. What is the function of the artwork?

f. What traditional role of the artist is exemplified?

4. Explain how the works of art fit into the context of the time period. Keep in mind that only art works that fit into the period of Middle Ages – Renaissance (created between 1350-1520 CE) will be accepted.

Decaffeinated means without caffeine

Decaffeinated means without caffeine

Science

In this week’s lecture, we read about Socrates’ concern for defining undefined terms as the first step in critical thinking.

Choose one of the statements below. Your task is to determine how the term is used to define your chosen example, and whether the definition is by example, by synonym, by an analytical definition. If you experience difficulty in determining which method of definition is being used, describe the difficulty and try to negotiate agreement with other class members. This exercise works best if students do not all choose the first example. If one example has been well discussed, choose a different example to discuss.

And here are the examples:

1. Decaffeinated means without caffeine. Steve Martin is my idea of a successful philosophy major. The Cheyenne perfectly illustrate the sort of Native Americans who were Plains Indians. Data, in our case, are bits of raw information collected from survey forms, which are then put in tabular form and analyzed. Bifocals are glasses with two different prescriptions ground into each lens, making it possible to focus at two different distances from the wearer.
2. Red is the color we perceive when our eyes are struck by light waves of approximately seven angstroms.
