How can community empowerment strategies influence participation
in forming a coalition to discuss and plan for emergency
preparedness, and what would be some of the procedures local
governments would be able to promote regarding risk-reduction
programs in the community while including a culturally diverse
audience for participation?
1 – What is the mechanism of UV aging of polymeric materials? 2
– Why the mechanical properties of polymers varies with processing
technique? 3 – How the dynamic friction of composite depends on the
filler’s nature?
Briefly discuss how does the incorporation of
aggregates influence strength of cement basis materials (hint
explain why strength of concrete is lower than strength of cement
paste)
Discuss how blogging and microblogging have changed the way
information is communicated and used to influence social
perception. Provide specific examples to illustrate your ideas.
Carbohydrates are the most difficult biochemical polymeric
materials to determine the exact structure. Describe the different
types of isomer of carbohydrates and give examples of each type.
And explain why it is difficult to identify the structure.
1) Dextran is a polymeric carbohydrate produced by
certain bacteria. It is used as a blood plasma substitute. An
aqueous solution contains 0.582g of the Dextran in 106 mL of
solution. It has an osmotic pressure of 1.47 mm of HG.
b) what is the molarity of that Dextran solution. Hint use the
osmotic pressure equation T=298k, R = 0.0821L ATM / mol k.
c) how many moles of dextran are present in the 106 mL solution.
Use the molarity...
1. What kinds of bonds would be expected in polymeric
materials?
2. State the difference between:
a) Linear and branched polymers.
b) Thermosetting and thermoplastic polymers.
Discuss the mechanisms used by the Bank of Canada to influence the money supply. Use a simple numerical example to illustrate this. What role does the reserve ratio play
