If a single crystalline layer of γ is growing between single crystalline substrate α and β, one might expect a completely_____

If a single crystalline layer of γ is growing between single crystalline substrate α and β, one might expect a completely_____ Correct Answer Straight α/γ and γ/β interfaces

If a single crystalline layer of γ is growing between single crystalline substrate α and β, one might expect a completely straight α/γ and γ/β interfaces, provided that no orientation related effect occur which might cause a faceted interface. In a polycrystalline layer grown between polycrystalline end members, the interfaces are not completely straight.

Which of the following statement(s) given below is / are TRUE? A: If side of each small cubes at bottom most layer is 8 cm, then maximum number of small cubes that can be put at bottom most layer is 12. B: If maximum of 48 cubes can be put at second layer, then side of each cube at second layer is 6 cm. C: If side of each small cubes at third layer is 1.6 cm, then maximum number of small cubes that can be put at third layer is 300.
Consider the growth of a microorganism in batch culture. When the substrate concentration is high, the cell density doubles every 0.75 h, the observed substrate yield coefficient is 0.3 g DCW/g, and substrate consumption is allocated towards biosynthesis (60%), maintenance (10%), as well as product formation (30%). The product formation is strictly growth-associated. The batch reactor is inoculated with 0.01 g DCW/L and 10 g/L substrate. Estimate the maximum cell density (after lag phase).

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. The IMF has pointed out that the fast growing economies of Asia face the risk of falling into 'middle-income trap'. It means that average income in these countries, which till now have been growing rapidly, will stop growing beyond a point - a point that is well short of incomes in the developed West. The IMF identifies a number of causes of middle-income trap-none of which is surprising-from infrastructure to weak institutions, to less than favorable macroeconomic conditions. But the broad, overall cause, says IMF, is a collapse in the growth of productivity. Which among the following is the most logical, rational and critical inference that can be made from the above passage?
