The book Toxic Discourse written by Lawrence Buell analyzes the nature of environmental discourse, the strategies, and tactics that people use to discuss environmental issues. The book outlines the use of toxic discourse in four main elements, which are:
1. The Shock of Awakened Perception: This element is used when environmental crises have reached a critical point, creating a shock factor in people's minds, leading to an awakening. This element is used in other works to shock people and make them realize the severity of the situation, and that they need to take immediate action to prevent further damage.
2. A World Without Refuge from Toxic Penetration: This element refers to the inability of people to escape from the toxins in their environment. This element is used in other works to create a sense of despair, making people realize that they are unable to escape the toxic environment they live in.
3. David vs. Goliath Scenario: This element describes the power dynamics between those who fight for the environment and those who destroy it. This element is used in other works to describe the struggle between environmental activists and corporations, with environmental activists portrayed as the underdog fighting against powerful entities.
4. Gothification: This element describes the aestheticization of environmental decay, making it appear romantic and gothic. This element is used in other works to create an aesthetic appeal to environmental destruction, making it more acceptable and fashionable.
Overall, Toxic Discourse by Lawrence Buell provides insights into the nature of environmental discourse, the strategies, and tactics used in discussing environmental issues. The elements of toxic discourse outlined in the book are used in other works to create a sense of urgency, shock, despair, and aesthetic appeal, making people realize the severity of environmental issues.

Make a plot of hardness vs. % reduction in thickness, assuming that % reduction varies linearly across the width of the specimen from 0 at the edge to 50% at the center.
To make a plot of hardness vs. % reduction in thickness, assuming that % reduction varies linearly across the width of the specimen from 0 at the edge to 50% at the center, follow the steps below:
Step 1: Take a specimen whose width is 50 mm. The reduction varies linearly across the width of the specimen from 0 at the edge to 50% at the center. Therefore, the reduction at a distance x from the edge is given by the equation: Percent reduction (ε) = 50 - (2 * x)
Step 2: From the given data, we know that hardness is directly proportional to the percent reduction in thickness. Therefore, we can write the hardness (H) as:Hardness (H) = k x Percent reduction (ε)where k is the constant of proportionality.
Step 3: Substitute the value of percent reduction (ε) in the above equation to get:Hardness (H) = k x (50 - 2x)
Step 4: Simplify the above equation to get it in the form of y = mx + c, where y is the dependent variable (hardness), x is the independent variable (% reduction in thickness), m is the slope of the line, and c is the y-intercept.Hardness (H) = -2kx + 50k
Step 5: Now we can plot the graph of hardness vs. % reduction in thickness using the equation derived in step 4. The graph will be a straight line passing through the point (0, 50k) and having a slope of -2k. The x-axis represents the % reduction in thickness, and the y-axis represents the hardness.
The graph will look like this: Hardness vs. % reduction in thickness plot
