I did not know much about compounded EVA, I would like to know about the type of aditive used? what is %age can be used? and what kind of properties can achive?and where it can be used?
GUEST, I have no idea what you mean by EVA. I hate acronyms since each can have a multitudes of meanings. It would be great if you could simple spell out your meanings. After all, we do have a language we all understand, and even high school graduates can write a little. It is unnecessary to in todays computing to use acronyms to save space (bytes) and is a lazy person's way of doing things.
However, acronyms can help to weed out those with no expertise in the field. Much like I am going to understand acronyms from my field such as SPT, CPT, HASP, SWPPP, GWMP, PID, ICP/MS, GC, etc... However, the acronyms usage can be limited to language and locations which would really limit your resources, even though other may have some expertise and use a different acronym for the same thing.
RCE, please look at this: http://chtank.org. Not to dispute you but sir, Acronyms are not welcome in my world. The weed out nothing. Even the difference between CO² and Carbon Dioxide can be disputed when one is speaking with a non-chemist. As a chemist, physicist, and engineer who has had to write engineering scope of work, I find the craftsman often had a great deal of difficulty interpreting acronyms. But then, I am retired now, so perhaps I have lost something in my old age.
To communicate clearly with the general public and contractors you should not use acronyms, and never use them without definition in specifications and contract documents. However, based on your example if you wanted chemical information regarding carbon dioxide from a chemist, you could use acronyms to weed out uninformed non-chemists, you could discuss CO2.Those who did not understand would obviously have very limited knowledge of the subject, and may not be a suitable source of information. It is a matter of the audience with whom you are seeking to communicate. Is it a select audience with highly specialized knowledge in the field, or a broad audience (including litigation potential). I never use acronyms in any contract documents, without defining them, to contractors or craftsmen. It is not that they have problems understanding, but rather they use them as a loophole to claim a lack of understanding in pursuit of change orders and added fees. Acronyms are part of a language understandable to a select few knowledgeable in the field where that acronyms specific meaning, as the user intends, is utilized. As such it is a good means to screen out those with limited knowledge.
BTW, interesting education, it must have taken a lot of work. I myself started as a physics major in college but switched to a double major in chemistry and soil science. Later obtaining my engineering MS. I don't know about recieving a BS in physics, then completing the core curriculum for a BS in chem to receive a MS in Chemistry, then completing the ABET core curriculum in engineering to recieve a PHD in engineering. That is a lot of work effort, with the 30 or so units of undergrad core curriculum to make up all the time. I found that annoying in my engineering MS program, it doubled the course work requirement. I would probably just go after a degree in a related field when i pursue my PHD.
I have always considered the craftsman as a valuable tool with whom I should communicate clearly and properly. If an engineer needs information of existing conditions in the field, what better source than the craftsman. The craftsman has spent years learning his trade, just as we spent years learning our trade, both in the field and in school. I, for one, will bend over backwards to make sure the craftsman with whom I work understand me and I will also bend over backwards to understand t what they tell me. The same goes with any "public" with whom I must cooperate in order to make our world a better place. However, what prompted me was the use of an acronym in the opening question; I simply did not know beyond a doubt what question was asked. For instance, DOE can mean both department of energy and department of education. Both of which I support and recommend for all engineers, BS, MS, or PhD. A fraternity brother of mine used to MIT site to bone up on his Physical Chemistry when applying for a lab assistant's position at Rice University, got the position and went directly into his PhD from BS in Nanotechnology. I stronly recommend you go for it now. I am retired and age 75, so my own continuing is simply to know reather than seeking degree honors.
Actually the best source as a engineer is a thorough understanding of industry procedures, and to go out to the field yourself and observe the conditions. It is also the best way to avoid potential problems that lead to unfairly limiting the potential project bidders, change orders and/or possible litigation. I typically use my own experience on previous jobs, and discussion with various trades contractors to evaluate specific methodology and approach, staging and scheduling, and current industry costs. however, I am always mindful of the obviuos bias towards over estimation in costs and schedules provided by such sources, and their interpretation of a accpetable reduction in QA/QC protocol applicable to all projects unless they have the potential to bid for the QA/QC also (in which case more is necessary).
As far as becoming a RA, I would have to evaluate the requirements for a PHD in various program alternatives. I current earn about triple what a RA does, so it is a big hit to my income, but most programs require at least a year in service as a TA or RA at the university. With the current bill for the federal government to offer a $10,000 loan forgiveness program for education for persons working as engineers, I might consider it sooner. ( I need to review the requirements of the final loan forgiveness program bill.)
Do not let them talk you out of ASHA and the Tailgate meetings, though, hehehe. Safety is of a major concern for their and our own good. and be sure you always take the hazard analysis seriously.
Tailgate meetings aren't the problem, it is when contractors show up non-compliant and just want to work that way anyways. I had a fencing company arrive on site with temporary fences stacked up to about 15 feet in the air once, stacked and secured with straps during transport. They wanted to unstrap the stacked sections of temporary fence and climb up the sides of the stack to remove sections from the top. You could see the whole stack swaying and tilting before they even climbed on it. They had no other means of unloading safely, so they had to leave the site.
Your contract should include compliance to the safety standards and a penalty for non-compliance. You did the right thing sending them back without unloading. I hope payment was withheld. Also, they need s stern waring that injury for non-compliance can result in a very heavy fine and that neither your insurance nor their insurance is valid and could be very, very costly to them. Of course, I am considering Texas Laws, I have no idea about California, but I bet it is much the same. I know most insurance companies are the same.
Well, yah, but the compliance penalty is immediate removal from the project, which actually doesn't benefit anyone including the client. The fencing company was a subcontractor, so we had nothing to do with payment, the contractors foreman was onsite and he was pissed that they were sent off site, not that they were working precariously without safety equipment. We would discuss the possbility of OSHA fines every morning, however, everyone already knows OSHA never randomly shows up to a site to inspect compliance, so they were not particularly worried. Subs like temporary fencing show up for 1 hour set up fencing and leave, odds are way against OSHA ever being onsite to inspect for compliance when those subs are onsite, even if a disgruntled employee were to call and complain to OSHA. The best we could do was there were bonuses for safe work in the contract and no penalty to owner for stopping work for non-compliance or removing a contractor/subcontractor.
Key words are if "death" or "Injury". BTW, although I was not an OSHA inspector, I was and am fully qualified as one. In fact, it was my knowledge of both the codes and regulations and their applications that lead to my title of Principle with a major engineering corporation (Parson's Engineering Corporation, Power and Petrochemical Division).
Yes, URS' major Oil Clients would prefer we pre-empt actions before the stage where the words "death" or "injury" apply. They just take a hard line of removal for almost any violation of safety policy.
