Scenario 5: leaks after thirty batches

You notice that significant leaks are occurring during the plant’s testing and start-up phases. These leaks are probably caused by the cheaper controls, inferior couplings, andthe inexperience of the plant operating team including Manuel. What should you do? 1. Have Manuel baby sit the batches timing them and constantly checking their temperature.2. Argue that it is necessary to immediately retrofit the plant with Lutz and Lutz controls.3. Argue that it is necessary to retrofit the plant with Lutz and Lutz controls but thisshould be done after the plant has been turned over to operations. Let them pay for it. Compare and rank these solution alternatives using the ethics and feasibility tests.

Scenario 6: should you let those plant jockeys make new stripper?

Wally: Well, this is what we’re going to give to operations when we hand over the plant. Is everybody okay it? CHUCK: Fred's the guy who’s got to put his name on it, Fred’s got to be alright with it...Fred: Well, the couplings still leak when the pressure is up. Wally: And we've alerted operations and given them specific instructions on how to maintain the connections.CHUCK: We've got Jen working on a lower temperature formula. That may make all of this moot. Fred: We haven't worked out the bugs on the last step of the automation...WaLLY: And next year, we'll retrofit the entire plant with L and L controls. CHUCK: This is how it works. We design it. We build it, we hand it over. They run it.We’ve done the best we can. No plant, no process, no system is ever completely perfect. WALLY: You built a plant that’s efficient. You've got your upgrades to the wastewatertreatment. Fred: Yeah, you're right. Um, for now Manuel or one of his guys can use the manualrelease valve. CHUCK: Okay. Time to let those plant jockeys make New Stripper.You are Fred. Should you sign off on the documents? Use the ethics and feasibility tests to test this solution

Conclusion: what did you learn?

    Some closing exercises

  1. How does the STS in Morales, Mexico differ from that of Puerto Rico. (A suggested PR STS can be found on the last slide of the presentation appended just below.
  2. In what ways (if any) should the CIAPR code of ethics be changed to respond to the problems that arise in "Incident at Morales"? Is it necessary to add more specific principles of professional conduct? Should more aspirational, value-based provisions be added.
  3. Obviously, it is best to direct changes in our STSs to avoid problems like those arising in "Incident at Morales." What kind of changes should we make in the stakeholder columns? Can professional societies like the CIAPR play a role in preventing these problems? Is this primarily a compliance role or can other roles be identified?

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
