Psychology and the Financial Crisis of 2007-2008
This draft: August 2011
I discuss some ways in which ideas from psychology may be helpful for thinking
about the financial crisis of 2007-2008. I focus on three aspects of the cr
Flexible connective tissue found in many areas of the body i.e
joints between bones, rib cage, ear, nose, bronchial tubes and
the intervertebral discs.
Not so hard as bone and less flexible than muscle
1) What are tendons?
2) What fluid is present in the joint and what is the
biological function of the fluid?
3) Explain structure and functions of skin with neat
4) Explain viscoelasticity and non linear stress and

Support to the cells
1) What are arteries and arterioles?
2) What are lung mechanical parameters? Explain
normal breathing mechanism using P-V curve
3) Explain the mechanism and functions of
cardiovascular system with neat diagram?
4) How is breathing air
Organ system that permits blood and lymph circulation
to transport nutrients to and from cells in the body
- Blood vessels
Includes: Pulmonary circulation, Systemic circulation
1) Significant features of non-Newtonian fluids?
2) How mucus play an important role in controlling
antigen present in the system?
3) What is meant by Pseudo-elasticity?
4) Short notes on i) Hookes law, ii) Newtonian and
Flow properties of blood
Refers to the movement and deformation of
blood and forces that produce that flow
Role of Blood:
- Transport medium
- Buffering reservoir to control the pH of bodily fluids
- Transports heat (centrally located tissues
Biofluids & Dynamics
Studies the way that fluids move in the
Obstructions in blood passageways
Smallest transport lines for blood/some

UNIT 4: Tissue replacement implants
Soft Tissue Replacement
Most tissues other than bone and cartilage are soft tissues
Most common types of soft tissue implants are :
Sutures and Allied augmentation
Large molecule composed of repeated subunits (monomers)
Monomer A substance composed of monomer molecules
Monomer molecule A molecule which can undergo
polymerization to form structure of a macro molecules
Monomer combine to form dimers, trimer
High modulus and ductility of metals make them suitable for
load bearing applications
Prostheses to replace a portion of the body such as
joints, long bones and skull plates
Fixation devices stabilize broken bones and other
