1. How is a brick veneer wall built? What are the correct steps
in this process?
2. Why do we need to use an SW brick for an exterior wall in New
England? And what type of mortar should we use?
Question 6
a. Using the example of brick laying in a construction site
clearly explain the following:
i. Push or Building-to-stock
ii. Pull or Building-to-order
iii. Push-Pull Point
b. Define Supply Chain Management (SCM). List and explain some
of the key benefits and challenges in SCM especially within the
context of a Construction Manager.
c. What is Just-in-time (JIT) approach and where did it
originate from? How does it help in the reduction/elimination of
waste especially in the context of...
Q1: Explain, with neat sketches, how is Kronig-Penny Model
useful to understand the concept of bandgap in solids
Q2:
Assume that Fermi energy is 0.20eV below the conduction band and
Nc =2.8x10-19 cm-3 and
ni=1.5x1010 cm-3 for silicon at
300K. Calculate:
1- Probability that electron occupies a state at conduction band
edge.
2- Thermal-equilibrium electron concentration.
3- Thermal-equilibrium hole concentration.
Explain how the primary transcript of a single eukaryotic gene
can produce different proteins, using Drosophila
sex-specific courting behavior as an example.
Briefly describe how genomic imprinting can be inferred from
inheritance patterns in human pedigrees.
Explain "clonal expansion" of lymphocytes and how it contributes
to the features of adaptive immunity, such as specificity,
elimination of pathogens and memory.
1. Explain how Na2CO3 of primary standard grade can be prepared
from primary standard grade NaHCO3? 2. Why is it common practice to
boil the solution near the equivalence point in the standardization
of acid with Na2CO3? 3. Calculate the molar concentration of a
dilute HCl solution if titration of 0.2694 g of primary standard
Na2CO3 required 38.77 mL of the acid (products CO2 and H2O).
