The widest point on a specific surface of the crown is called the:

Lysozymes and antibodies are components  of saliva.

Which of the following expenditures could be included as part of the cost of land?  

(1.3 points TOTAL) Consider the Maxwell model for viscoelastic behavior (see diagram below).  Provide the following information for this model: (0.3pts) Provide the governing equation for total stress in the system in relation to the components of the model. (0.3pts) Provide the governing equation for total strain in the system in relation to the components of the model. (0.3pts) Provide the final differential equation to describe the total strain in the system in relation to total stress.  (0.2pt) Which does the Maxwell model best represent: creep or stress relaxation? (0.2pt) In general, how could the Voight and Maxwell models be improved?

(1.25pts) A new polymer company is charged with producing monodispersed batches of polymers. You lead the quality control group and have to make some decisions regarding the each batch. The most recent quality results are found below.  (0.75pts) Characterization of the polymer via gel permeation chromatography demonstrated three distinct fractions within the synthesized batch. Calculate the number average molecular weight and weight average molecular weight of the polymer sample. Fraction Molecular Weight (Da) Number of Chains A 5,000 50 B 1,500 2,500 C 18,000 10 (0.5pts) To pass quality control regulations, the polydispersity index must be less than 1.2. Determine whether or not this batch passes the company standards. Explain what factors from the polymer sample may have contributed to the passing or failing grade.

(2pts TOTAL) Many intraocular lenses (IOL, commonly known as contacts) are made up of polymethylmethacrelate (PMMA). Although advancements have been made, there is still evidence that PMMA is not entirely biologically inert. To address this one group has looked at the effects of heparin surface modification (HSM) to enhance biocompatibility of PMMA lenses. Aqueous flare is defined as the breakdown of the blood-aqueous-barrier which causes blood borne proteins and cells to leak into the space inside the eye between the iris and the cornea’s innermost surface, the endothelium. Answer the following questions below.  (0.4pts) Explain the significance of the following plot and what you have been told about aqueous flare in regard to potential immune response. *What happens, why, and how VERY BRIEFLY* (0.4pts) The following plot interrogates fibroblast adhesion to the IOL over time. An asterisk (*) represents a statistical difference. Describe the results in this figure AND their biological significance. *What happens, why, and how (type of tissue) VERY BRIEFLY* (0.4pts) The following plot interrogates foreign-body giant cell adhesion to the IOL over time. An asterisk (*) represents a statistical difference. Describe the results, why this happens, and their biological significance. (0.4pts) Based on the results in these figures, would you recommend continued production of HSM IOLs? Justify your answer. (0.4pts) Assume you decided to add foreign cells to your HSM polymer implant. Describe how the body would respond to this combinatorial (cells + synthetic biomaterial) implant. Specifically describe the sequence of events in terms of the types of inflammation and types of tissue formation.

(0.5pts) A patient underwent hip surgery 3 days ago and is experiencing significant pain and discomfort at the implant site. The surgical team is concerns about a possible infection. State and briefly describe which category of implant associated infection the patient may be experiencing.

For the amplifier below, assume VEB(ON)=0.7 V, β=100 (take IC=IE) and VA Early voltage is infinity. All capacitors are very large. Which one of the following is the DC load line equation for the amplifier? pnpCE.jpg
