Question 11:  a. With a real space schematic of Miller planes near an edge dislocation, explain and illustrate how changes in the diffracting condition enable a dislocation core to be located with weak-beam dark-field imaging.                                                                                    (3) b. A face center cubic (lattice parameter 0.45 nm) is put into a microscope operating at 300kV and the crystal tilted into the [011] projection.  You index the diffraction pattern as shown below.  The material may possess partial dislocations with Burgers vectors [11-2]/6, [1-21]/6 and [-211]/6.  By slightly tilting you can set up 2-beam conditions to perform g.b analysis. By considering the 4 reflections nearest the direct beam, determine if you are able to differentiate these three dislocations.                                                                                                   (4) c. You then image the dislocations using weak beam dark-field imaging with the (-11-1) beam. Estimate the value of excitation error for g-2g and g-5g conditions.                               (3)

Zara Owner Inditex’s Sales Grow as It Holds Off on Major Price Hikes – WSJ 11 01 2024.pdf Based SOLELY on the article above (ABSOLUTELY NOTHING FROM THE INTERNET – IF SO, THE WHOLE QUESTION WILL BE GRADED ZERO!): In a SWOT analysis approach (without using the 4 quadrants), please mention 3 Strengths, 1 Weakness, 3 Opportunities, and 1 Threat – ONLY based on the content within the article. REMEMBER: Strengths and Weaknesses are meant to be INTERNAL; whereas Opportunities and Threats are meant to be EXTERNAL! Avoid repeating the same strength or weakness, etc., in different words or sections from the article. So 8 answers in total. 1.5 points each. Strengths: 1. 2. 3. Weaknesses: 1. Opportunities: 1. 2. Threats: 1. 2.
