ou are testing a long-dwelling catheter for its biological response using a rat model. After implantation for 4 months you explant the catheter material and surrounding tissue. Histology shows the catheter material surrounded by a thin layer of aligned collagen that is, in turn, surrounded by numerous polymorphonuclear cells. What has occurred? Describe the short term and long term events that led to this outcome. Note: the fact that this is a rat model rather than a human is not the issue - the model is fine.

At 250C, the interfacial tension between water and n – octyl alcohol is 8.50 dyne/cm. if the surface tension of n-octyl is 27.53 dyne/cm and that of the water is 72.75 dyne/cm, predict whether water spreads on the alcohol by calculating a) Work of cohesion of n-octyl b) Work of adhesion and c) the spreading coefficient of water on the alcohol. Will alcohol spread on water?
Archimedes established his principle while investigating a suspected fraud in the construction of a crown. The crown was made from an alloy of gold and silver instead of pure gold. Assume that the volume of the alloy was the combined volumes of components (the density of gold is 19.3g⁄(cm^3 ), the density of silver is 10.5g⁄(cm^3 )). If the crown had a weight of 9.81 N in air and 9.10 N in pure water, what percentage of gold (by weight) was it?
An open vessel containing liquid water stands in a sealed room measuring 3.0m wide x 3.0m long x 3.0m high. The temperature of the room is 300K and, over time, some of the liquid water evaporates. Eventually, the liquid water level in the vessel stops changing. How many grams of water will be in the humid air within the sealed room? Show all work
One of your employees is complaining of knee pain on the R. While assessing his workstation, you noted that from a sitting position (starting position: 90 deg flexion), the employee needs to exert a lot of effort to extend his right knee to 45 deg from the starting point. The length of the limb (from the tibial tuberosity to the heel area) is measured to be 38 cm. What now is the linear distance traveled by the limb from the initial position to 45 degrees of knee extension?
Young's, Shear, and Bulk Moduli are mechanical properties of biomaterials. Considering that a biomaterial undergoes an elastic deformation, describe with equations how its nominal and shear stresses as well as hydrostatic pressure relate to its engineering strain, shear strain and volumetric change respectively.

The crux of the problem asks you to compute the elastic modulus of a pancake--for this we give you numbers that we got from our own measurements of the pancakes. The last question asks you to hypothesize about which ingredients are playing the role of flour in the gluten free recipes. If you find this topic interesting, you may want to consider exploring something like this for your final project, and design an experiment to understand the difference between the normal and gluten free recipe and try to manipulate the gluten free recipe to better resemble the normal pancakes.If you choose to make the two recipes and compare them in your own kitchen, make sure you use exactly the same protocol for each recipe: In our trials, we made the batter, and then cooked on a skillet, using 1/4 cup of batter per pancake, and flipped when the edges were firm and golden, about 4-5 minutes on each side.Consider a stack of six pancakes. Each pancake is made of 1/4 cup (approximately 60 mL) of batter,…
You are still a comparative evolutionary biologist that studies biomechanics and have made an amazing discovery. You’ve dug up a fossil related to the species above that has a hollow rectangular cross section in their femur-equivalent. The bone has a cross section that is 20 mm by 15 mm with a uniform 5 mm wall thickness (A) Calculate the first- and second-area moments for composite-shape bone geometry. (B) Discuss the implications of having a hollow bone. Consider the differences in the area moments as well as the relative strengths given the cross-sectional areas of the bone.
Geochemical Box Models - please use same terminology found in question Consider an element X exchanging between two geochemical reservoirs A and B. Let MA and MB be the masses of X in reservoirs A and B, respectively; let tA and tB be the residence times of X in reservoirs A and B, respectively. Further let M = MA + MB be the total mass of X in the two reservoirs combined. Consider a situation where additional mass M' is injected into reservoir A at time t=0 increasing the total amount of element X in the system from M0 to M1, with no further injection at later times; further assume that tA >> tB, that the total mass in the altered system is M1 = M0 + M', and that M0 << M'. Give an expression for MB(t) as a function of M1, tA, tB, and t. What is the characteristic time for MB to approach steady state? What is the characteristic time for MA to approach steady state?
