In experiments conducted at Pavlov's lab, Vul'fson and Snarskii placed sand in a dog's mouth. The first time the sand was placed in the dog's mouth, only the feeling of the sand in the mouth elicited salivation. However, after sand had been placed in the mouth several times, the sight of the sand also came to elicit salivation. The dog had learned to associate the visual features of the sand with its textural features, which illustrates a. temporal coding. b. trace conditioning. c. evaluative conditioning.

You are evaluating the productivity of a well in the first quarter of a bounded rectangular reservoir. The reservoir has a length-to-width ratio of 2:1. You are provided with the following data: Average reservoir pressure, P: 2500 psi Permeability, k: 100 millidarcies Reservoir thickness, h: 30 feet Fluid viscosity, μ: 2 cp (centipoise) Formation volume factor, B: 1.5 rb/stb (reservoir barrels per stock tank barrel) Total drainage area, A: 160 acres Wellbore radius, rw: 4 inches Skin factor, S: 5 Given that the reservoir is rectangular with a length-to-width ratio of 2:1, calculate the productivity index (PI) for this vertical well using the Pseudo Steady State Solution.

Please answer this question and show all work. I just need this for Sample 1 so I can do the rest on my own. Question 1: The following five images are microstructural images of Brass samples at 100x magnification after going through the grinding, polishing, and etching steps. Identify the following for each sample: a. What information can you find on the phases present? b. What is the grain diameter? c. What is the estimated grain size of the microstructure using N=2n1) where N is the average number of grains per square inch at a magnification of 100x and n is the grain size number. The grain size number, n, is used extensively in the specification of steels. If the value of N is established at a magnification other than 100x, then this relationship for establishing the grain size number, n, is invalid. Note: Table 2 compares the ASTM grain size number, n, with the useful measures of grain size in terms of N= grains per square inch at 100x, grains per square millimeter at 1x, and average grain diameter in millimeters.

Use Microsoft Excel spreadsheet to calculate the depreciation charge for different depreciation methods and to compute the book value of different assets using different depreciation methods. Also, determine the best alternative using the present worth of after-tax cash flows (ATCF) and perform a sensitivity analysis. Solve example 17.3 using a different depreciation method: DB (declining balance), DDB (Double declining balance), SLN (straight line), and SYD (Sum of year digits) (each method on a different page). Also, compute the MACRS method. Decide the best alternative (depreciation method) by comparing the after cash flows using the present worth method. Questions: 1. Which depreciation method gives the higher after-tax cash flow? 2. If revenues decrease each year by a constant of $20,000 (e.g., in year 1 $200,000, in year 2 $180,000, etc.), will your decision of the best depreciation method change? Why or why not? Construct another set of five (5) Microsoft Excel sheets to answer this question. 3. If revenues increase each year by a constant of $20,000 (e.g., in year 1 $200,000, in year 2 $220,000, etc.), will your decision of the best depreciation method change? Why or why not?
