End the Use of Live Pigs in Baystate Medical Center’s Trauma Training Program

Immediately replace the use of live animals in Baystate’s Advanced Trauma Life Support (ATLS) program with an American College of Surgeons-approved alternative such as the TraumaMan System. Baystate’s state-of-the-art medical simulation center, which currently owns TraumaMan, affords you the opportunity to seamlessly transition to nonanimal training methods.

Your program is outdated and unnecessary. Finally it is mainstream to realize the impact medical research on animals is having on our society. The only people that will now agree with this are people who view animals as property and disposable. Trust me when I tell you that as long as I have air in my lungs I will do what is necessary to get your program shut down.

What kind of sick person finds value from needless animal torture? There is a strong correlation between these people and those that have little respect for women in general. These are also the same people you will find who wear white robes or wear swastika’s on their arms.

Believe you me the poop is getting ready to hit the fan if you don’t take immediate steps to change this policy. We can easily label your school and get you worldwide bad press if that’s what you desire.

Say NO! To Animal Research

Being against animal research is not at all a position of extremism as you put it. This is a basic core rights that all life has on earth. You need to understand it is finally now mainstream to treat animals with respect. We all know its no more necessary to test a lab monkey than it is to throw good recycling in the trash. Its nice to see the public becoming more aware and taking a stand on this issue. http://speakingofresearch.com/2009/09/14/raising-voices-animal-research-advocacy-and-community-engagement/

You know how to skew your stats dont you? You are only reporting the public sector of animal research. I would guestimate that the stats generated represent only 20% of the complete numbers. Unfortunately I have seen firsthand what happens in many testing facilities.

The only reason why you push this is because its the cheapest way for you to test. We all know it can be done without animals. In my life it is a goal that I help end animal testing and research for good!

Is cloning a shady subject?

I think cloning is a good thing for all the right reasons. Nothing or noone, is free of its negatives. For every plus there is a minus. Religion wont stand with it because they feel it takes God out of the creation process. As a Christian I disagree. I feel that God is giving us a cure to many of our problems by giving us cloning. Did Jesus not say to the shepherd that even on Sundays he should retrieve his wayward sheep?

To me its not shady at all. God is the giver of life, not science. Either you believe this or you dont. But the religious people say they believe this but when it comes down to it they believe that man or science creates life and therefore all cloning is a terrible sin. I call bs. To reject cloning is complete stupidity. I cant honestly believe if one of these people were on a death bed, they would refuse a cloned organ. So much hypocracy in the church!

Using solar heat to power air conditioning

Using solar heat to power air conditioning

Southern California Gas Co. is testing systems that use less gas and electricity and is inviting businesses to view the prototypes on the roof of its Downey research facility.

Everyone knows solar power can heat homes and generate electricity.

But on a rooftop in Downey, Southern California Gas Co. engineers are using solar mirrors to cool down their offices.

Engineers are testing two technologies that use mirrors to concentrate sunlight onto pipes with water running through them. The heated water powers a thermal process in a chiller that cools the cold water used in air conditioning units.

“When we tell people we heat water up only to cool it down, they don’t get it at first,” said David Berokoff, a technology development manager at SoCal Gas. “But all this technology has been around for a while. We’re just trying to bring it together so we can get it out to our customers as soon as possible.”

The initiative is the latest in a move by SoCal Gas and its parent, Sempra Energy, to wean businesses off gas and push them to use more solar power. For businesses, the technologies could mean substantial savings.

Beyond the potential environmental benefits — the sun is a nonpolluting, renewable source of energy — the solar systems undergoing tests could help businesses slash air conditioning costs as much as 60%, Berokoff said.

The effort may seem counterproductive for one of the nation’s largest natural gas distributors, but it’s part of a broader move by the company to reposition itself as a renewable energy provider, SoCal Gas officials said. Sempra, which also owns San Diego Gas and Electric Co., expects to spend $10 million this year researching and developing “green technologies.”

The research project is only 4 months old and solar-powered cooling probably won’t reach the gas company’s customers for another year or two, but the gas company is already wooing businesses to the rooftop of its Downey research facility.

“When they make an investment in this sort of technology, they are in fact keeping their company viable and making sure they are changing as their customers’ needs change,” said Bob Phillips, a spokesman for Coca-Cola Bottling Co. of Southern California, which is watching the tests to see whether such technologies would make sense for several of its bottling plants. “It’s a very long-term view, but it’s the right view to have.” 

The gas company has been checking out competing solar-thermal cooling technologies from two companies to see which would work best on the roofs of warehouses, manufacturing plants and other commercial buildings.

The research could cut the cost of the systems and bring them to market sooner, Berokoff said.

The rooftop prototype systems, which include the mirrors, pipes and computer-automated solar trackers, cost about $200,000 each — about the same cost as the entire traditional air conditioning system installed in the 45,000-square-foot Downey building, he said.

The developers hope to slash that price by at least half before it reaches commercial customers.

SoCal Gas is comparing systems developed by Sopogy Inc., based in Honolulu, and HelioDynamics of Britain. The testing is expected to run until the middle or end of next year, he said, after which SoCal Gas plans to compare the results with similar mirror-based systems from other manufacturers.

Sopogy’s and HelioDynamics’ systems are similar: Both use mirrors to aim the sun’s rays at water pipes, and when sun isn’t available to heat the water — at night, for example — both rely on gas as a backup. 

The differences between the two systems lie in the shape and size of the mirrors used and in the placement of the water pipes.

Sopogy uses several 12-foot mirrors that curve upward, reflecting sunshine onto a pipe running just above the center of each mirror. HelioDynamics uses slabs of small, flat mirrors that reflect the sun’s rays onto a single pipe above them.

Both systems use computer-automated trackers to tilt the mirrors throughout the day as the sun moves across the sky.

The hot water in both systems is heated to temperatures just under 200 degrees and collected in a storage tank. Then it goes through an absorption chiller that cools the cold water used in the building’s fan units.

Non-solar systems use gas or electricity to heat the hot water before it goes through the chiller.

Sempra likes that the two solar systems can work alongside existing gas and electric systems, said Hal Snyder, vice president of customer solutions for SoCal Gas.

“People want renewable sources of energy, but we don’t think people want a switch that just happens overnight,” Snyder said. “By using gas or electricity as a backup, we’re not having to replace our infrastructure, and our customers know they won’t have to get into something experimental.”

The demonstrations are also helping developers of the technology, said Al Yuen, Sopogy’s director of corporate development.

“The gas company is giving us a stage to demonstrate what we can do for their customers,” Yuen said. “They bought our mirrors, bought our system, and now they’re using it and showing it off. It helps tremendously.”

Another benefit for the developers, Yuen said, is seeing the systems in daily use, up against competitors’ — with all the information shared.

This information from the project will be a deciding factor for most SoCal Gas and Sempra customers when the technology hits the market, Coca-Cola’s Phillips said.

“It’s easier to take that plunge when you have an example of the technology in place and you can point to numbers and say, ‘That’s effective, that saves money, that’s worth doing,’ ” he said.
