Said a representative of The Enough Project , another human rights group , "In easternCongo , you see child miners [ with ] no health or safety standards . Minerals are dug byhand , traded in sacks , smuggled across borders . "Once mined – whether in the Congo or elsewhere – raw coltan made its way through acomplex , multistep global supply chain . Local traders sold to regional traders , who shippedthe ore to processing companies such as H.C. Starck ( Germany ) , Cabot Corporation*( United States ) , and Ningxia ( China ) . Their smelters produced refined tantalum powder ,which was then sold to parts makers such as Kemet ( United States ) , Epcos ( Germany ) , andFlextronics ( Singapore ) . They sold , in turn , to original equipment manufacturers such asDell ( United States ) , Sony ( Japan ) , and Nokia ( Finland ) .*By the time coltan reached the end of this convoluted supply chain , determining itssource was nearly impossible . Steve Jobs , then the CEO of Apple , commented in an e- mailin 2010 , "We require all of our suppliers to certify in writing that they use conflict – free*materials . But honestly there is no way for them to be sure . Until someone invents a way tochemically trace minerals from the source mine , it’s a very difficult problem . "As public awareness of atrocities in the Congo grew , governments began to take action .The Organization for Economic Cooperation and Development , an alliance of mostlyEuropean nations , issued guidance for companies that wished to responsibly source min -erals . In 2010 , the U.S. Congress passed the Wall Street Reform and Consumer ProtectionAct ( also known as the Dodd -Frank Act , and further discussed in Chapters 7 and 13 ) . Thislaw included a provision , Section 1502 , which required companies to disclose whethertantalum , tin , tungsten , and gold used in their products had come from the DRC or adjoin -ing countries . Companies were required to file their first Section 1502 reports in 2014( although some business groups had sued to overturn the requirement , saying it was tooburdensome ) .Companies also acted . For its part , Intel sent teams to more than 86 smelters and refin -ers in 2 1 countries , educating their partners about conflict minerals and collecting infor -mation about the origin of raw materials they processed . The company collaborated withother companies in the Electronics Industry Citizenship Coalition ( EICC ) to develop aConflict -Free Smelter Assessment Program , a voluntary system in which an independent*third – party auditor evaluated smelters and refiners and designated them as conflict-free .Minerals would be "bagged and tagged " and then tracked through each step of the supplychain .Intel was particularly concerned that it exclude from its products only conflict miner -als , not those coming from legitimate mines in conflict areas . To this end , it worked withgovernment agencies and civil society organizations , including the U.S. State Department*and RESOLVE , an NGO working to map the conflict mineral supply chain , to form thePublic – Private Alliance for Responsible Minerals Trade . This multisector initiative workedto support responsible mines and to develop effective chain- of-custody programs in theCongo . In a statement published on its website , Intel said it "believes that an effectivesolution to the complex issue of conflict minerals will require coordinated efforts by gov -ernments , industry , and NGOS . ‘"Sources : " Intel ‘s Efforts to Achieve a Conflict -Free Supply Chain , " White Paper , 2014 , www . intel . com ; " Intel Unveils Conflict -Free Processors : Will the Industry Follow Suit ?

Question:The heart is an organ that creates pressure to circulate blood through a system of tubes (arteries, capillaries, and veins) that bring critical chemicals to all parts of the body. The quantity of flow results from a combination of the pressure differential created by the muscles in the heart and the resistance of the network of tubes. (See Internal Flow: The H-P Equation.) In this problem we will explore the relation of the size of the heart to the pressure that it can deliver. 

By Dr. Jana – Own work, CC BY-SA 4.0, Link 

A. Toy Model

In order to get a sense of the relationship between the pressure in the fluid in the heart and the forces in the muscles of the heart, let’s begin by considering a highly simplified (toy) model of the heart — a simple sphere providing tension filled with a fluid at a higher pressure than that outside it. (See The Laplace Bubble Law.) The excess internal pressure (above the external pressure) tries to open the bubble while the surface tension tries to close it. The result is the Laplace bubble equation that relates the surface tension γ (gamma — unit of force/length) to the pressure difference, Δp, to the radius of the bubble, R:

Δp = 2γ/R .

A.1 If we are modeling the heart as a spherical bubble, estimate the radius of a typical heart and how much that radius changes during a heartbeat. Discuss how you found the values you chose and why you chose them.

A.2 The excess pressure of the heart in a healthy human varies from 120 mmHg (systolic) to 80 mmHg (diastolic). Using your value for the relaxed heart and the diastolic pressure, get and estimate for the surface tension in the relaxed heart muscle. (Please convert to SI units of Pascals.)

A.3 From your estimate of how much the radius changes during a heartbeat and the systolic pressure. Can you estimate the change in the tension of the heart muscle during a heartbeat? Is it reasonable to consider that the tension does not change?

Did the tension increase or decrease during the heartbeat that drove the pressure up? We have a certain expectation (what is it?) but our model is so simplified that it might not yield the expected result. Discuss what you found, what you expected, and whether the result is plausible.

A.4 In this simple model, there is a simple relationship among our three variables: pressure difference, radius, and tension in the muscle (really surface tension – force/length, not force). From this relationship, what would you expect for a larger heart? Is it easier or harder to provide the same pressure difference as in a smaller heart? This has implications both for the medical condition of an enlarged heart and for a comparison of the hearts of smaller vs larger animals. Discuss the implications of the Laplace Bubble equation for these two situations.

B. Improved model

As we can see from the reasonably realistic image at the top of the page (a CG image – not real), the thickness of the heart wall is not small compared to the radius. Let’s explore some aspects of an improved model in which we take this into account. 

Since the tension is provided by muscle fibers, what is more likely to be a good parameter describing the force in the heart is surface tension per unit thickness of the heart, or circumferential stress, σ (sigma). We’ll use the Greek “tau” – τ – to represent thickness. (In handwriting it looks like a “t” with the bar moved up to the top and the curve at the bottom turned to the left instead of the right.) Let’s model the tension in the heart as

σ = γ/τ

Our model says that as the thickness changes, so does the surface tension and the surface tension that can be provided is directly proportional to the thickness.

B.1 Derive the equation for the relation of the pressure difference provided by the heart muscle and the parameters of the heart, σ, τ, and R.

B.2 Now suppose that the inner radius of the heart is R and the outer radius is R + τ. Still assuming a (now thick) spherical bubble, find equations for the volume of heart muscle, Vheart, and the volume of fluid contained in the sphere, Vblood. 

B.3 Suppose that the heart is enlarged by 20 percent (the radius increases by 20%) but the volume of muscle does not change. Find an equation for the new thickness of the heart wall. (If it’s too messy, simplify by assuming that τ/R is small and can be ignored compared to a constant factor, and that (τ/R )2 can likewise be ignored.)

B.4 Continuing with the 20% enlarged heart, find the ratio , the surface tension in the enlarged heart compared over that in the heart before being enlarged. (Assuming γ is constant.)

C. Next steps

Even the improved model is not very good. It doesn’t include the multiple chambers of the heart, for example. How useful do you think this analysis is? Might it only be useful for simpler animals such as worms that have an “aortic arch” rather than a full heart? Or perhaps for animals with two chambers hearts like fish? Or does it have value for thinking about the human heart?
