Acclimation drips

I keep hearing that if you were acclimating a fish with a drip, you acclimate the temp first then do the drip. But then it's said that an acclimation drip is not recommended because of the difference between tank temp and bag temp would put stress on the fish.
Then wouldn't it make more sense to do the drip first then the water temp? Then again, if you do a 3 drop per second drip, the temp change would be more gradual than "bag in the water" temp change. That's not Biology. That's simple Physics. Depending on the volume of water in the bag when you start the drip, at only 3 drops per second, the total mass of the water in the bag would dominate the temp as a whole and if there were to be any change in temp, it would only be about 1/2 to 1.0 degree. If a drip takes 20 to 30 min, even if it's a 1.0 degree temp change, I don't think the fish would even notice that.
Certainly a temp change in the ocean caused by Mother Nature alone is more drastic than that. I may be a newbie when it comes to fish but I do know a little about simple Physics. Please feel free to correct me if you think I'm wrong, but if you really think about it, my theory makes sense.

I drip acclimate most items but not all. Some items (primarily coral) I just temp acclimate by floating the bag. It really depends on what it is and how sensitive it is. If I decide to drip acclimate, all I do is pour the creature and water into a 1 gallon pitcher. I then set up my drip line and adjust as necessary. I will scoop water out and pour it down the sink as needed. After 1-3 hours (depending on the creature) I scoop it out of the pitcher and put it in the tank.

If I purchase the fish from the LFS, I also just float the bag as was already mentioned...However, Saxman made a valid argument that fish that are shipped, and have been in the bag for so long should just be temp acclimated and then just opened and released into the (what should be a QUARANTINE) tank. He says the waste in the bag is far more a threat then the shock of different SG levels. I must admit that it worked with my delicate seahorses.

What about inverts like snails and reef shrimp? Sg if 1'019 at lfs, and my tank is 1'025 how do I do that.. I am floating and adding water but for how long?

Is say soak the bag to get temp close. Then add some water, I jus add some to the floating bag and use my magnet scraper. After a few scoops of water into the bag they will be acclimated. Maybe thirty minutes total. My LFS runs their tank close to my salinity so not much of an issue. Snails can live out of water for a short period. I would just soak the bag for twenty and then dump the water through my net. Shrimp should be fine as well.
Never had a fish, coral, or invert die from a transfer into the tank.
 
If I order online, I follow their acclimation policy. I do agree about being careful with items that have been shipped. I've read a lot online about things like possible ammonia spikes. I would think that if where you purchase your livestock from has a good return policy, they will advise you what acclimation method works best with their livestock. They don't want to lose money. This theory of mine may not be true if you purchase your animals from a big chain store, or at a LFS that has hired staff who isn't knowledgable. They aren't necessarily worried about things like profits, so may not care if you have to return a dead animal for credit.

The author of this week’s cover article answers questions about what goes on in Nabi Saleh, a West Bank village where protests occur every week against the Israeli occupation. While policymakers debate about whether or not the United States is in a state of relative
decline, defined as a steady loss of its edge over rising powers such as China in terms of military might and economic affluence, one question sits quietly in the background:
If we are in decline, then what?MIT political science PhD candidate Joshua Shifrinson has some ideas. His dissertation, “Life on the Downward Slope: Explaining State
Decisions to Support or Exploit Declining Great Powers,” assumes decline as a given. And the answers he has found in terms of what’s next run counter to recent strategic military moves. As a result, his work has spurred its own ongoing policy debate.When Shifrinson came to MIT in 2006 from Brandeis University, where he had studied politics and history, he had, he says, “a 22-year-old’s interest in the military.” His interests were firmly rooted in the events of the time, such as the Iraq war, which began and surged during his undergraduate years.He came to MIT to mature his ideas and put them to work. “Analyzing real-world political questions scientifically is very hard to do,” he says. “MIT is the best at bringing rigorous academic skills to bear on policy-related questions.”Shifrinson
built
his skills while at the same time paying attention to news and talk among professors and speakers about the rise of China and India.
Then, when it came time to develop a question for his thesis, the

real-world shifted again.
“The great economic crash occurred,” he says.
“It just smelled like great power rise and great power decline.”Taking notice, Shifrinson connected his interests in history and military strategy with current events and chose to

focus his graduate research on trying to understand how economic and political change affect international security.In a nutshell, Shifrinson found one
measure that strongly influences the best strategic security approach for a great state in decline: the distribution of power.
The concept of balance
of power
is as
old as history itself. Yet among policymakers today, it isn’t always granted as much weight as other, more modern factors, such as open economies
and democratization. While

Shifrinson agrees that these other factors matter, his work suggests that balance of power theory should not be
ignored. Especially
not in a world where many countries
are vying for power.In a bipolar world, similar to that during
much of the 20th century where two superpowers competed for dominance, “one superpower’s
decline gives the other superpower a strong incentive to prey upon its weakness,”
Shifrinson says.
“But the declining state can still use

its military to deter predation.”
Maintaining expensive military might, even in the face of decline, gives the other superpower pause.But in a multi-polar world — for example, in modern-day Asia, where China is strong, India is rising and Japan and Russia maintain facets of
their former might — the best strategy for a United States in decline is to back off. “Making an effort to maintain
a regional power hold” — as the United States did this past fall with the strategic pivot toward Asia — “encourages allies to take a free ride at the expense of the declining nation,” Shifrinson says. “At the same time, it spirals up competition with rivals.”While Shifrinson isn’t looking for an immediate seat at the policymaking table, he would like to find room in his career to contribute to policy debates
that influence real-world security decisions. “It seems unfair to talk about the real world all the time without actually engaging in it,” he says.Until then, his near-term
plans involve searching for a university teaching position.
“Political science is one of the
few disciplines where everyone has something to say and some insight to offer,” Shifrinson says. “Teaching
students how to intelligently grapple with real-world political issues is rewarding work.”Hours

version of the mixture did not undergo a foam-stability test.

The president shouldn't be afraid of the sensible measures he endorsed as a candidate.
Pepco's multimillion-dollar
plan to reduce power outages and improve reliability was "cobbled together" without detailed study and could fail to achieve its goals, a team of independent consultants has found. The

Media Lab, Cameron met
with associate professor of media arts and sciences Cynthia Breazeal, who demonstrated some of her group’s recent robotic creations, which are designed to
respond to humans’ emotions. He also met with Hugh Herr, an associate professor of media arts and sciences and of health
sciences and technology, who works on advanced prostheses for amputees. Herr demonstrated some
of the new devices under development in his lab — including the
advanced foot-and-ankle prosthetics that Herr, a double amputee,
uses himself.Cameron met

informally with a small group
of students and recent alumni who have started
businesses, or are in the process of doing so. The seven young entrepreneurs each gave a brief introduction to their inventions or concepts for a startup; Cameron then asked questions about their projects.Fiona Murray, the Skolkovo Foundation Associate Professor of Entrepreneurship at the MIT Sloan School of Management, led that session. Murray, a British citizen, told Cameron, “It’s really the students who are the star of the show.” After the prime minister’s visit, she added, “He did seem impressed, and he seemed to be enjoying himself.” Murray said the young entrepreneurs who Cameron met “represent the diversity of students here on campus,” coming from different departments yet often engaging in interdisciplinary projects. “I think he was trying to get at what makes entrepreneurship part of the ecosystem here,” said MIT Sloan graduate student Bridget Akinc, who was part of that group. “Is it the academics? [He was] trying to really get at the idea of, can you take a university environment and create more of a culture around entrepreneurship? He asked, ‘Does everybody come here with a business idea, knowing that’s what you want to do? Or do you create it while you’re here?’ And there was a combination of responses that really covered the gamut.” “We all came [to MIT] wanting to do something with impact,” Akinc added, “and entrepreneurship seems to be a vehicle for a lot of the teams that have come out of MIT.”Elliot Cohen, an MBA student at MIT Sloan, said, “I really appreciated it, and I appreciated his questions. I think it’s very difficult, if you’re not inside an ecosystem like this, to appreciate the subtle interactions that make up the foundation of it and are so important. The fact that he really spent some time getting to know people like us who are right in

the middle of it, to me, is really encouraging. He’s

not just trying
to analyze it from the outside.”Akshar
Wunnava, a senior majoring in chemical engineering, said, “It was a pretty cool experience, especially to be an undergraduate and to share how my experience here at MIT has shaped what I’ve learned about business.” Wunnava said he is working on a startup to develop bacterial batteries for use in off-grid villages. After the young entrepreneurs gave Cameron brief descriptions of their
business ideas, “He was really sharp, asking us the right
questions,” said
Danielle Zurovcik SM ’07 PhD ’12, whose startup —
which grew out of a class project — aims to

develop a
device fat burning furnace the healing of wounds.
Because time was tight, “We actually had to stop him from asking questions, because
he was so interested in what we were working on,” she said.
“He was genuinely interested in hearing us.”Zurovcik said Cameron noted that many universities around the world have tried to become centers of innovation and entrepreneurship, but
few have done so as successfully as MIT.
Cameron, she said, seemed to be very interested in learning, “How does MIT do it successfully?” Toshi-Aline Ohta Seeger the wife of folk music legend Pete Seeger has died at the

Sprouse 'wasn't comfortable' with DC Comics' decision to hire Orson Scott Card to pen an installation of Superman comicsThe comic book artist who was due to work on the latest Superman series has pulled out of the project, after a row over the appointment of an anti-gay campaigner to write
the stories.Chris Sprouse made the announcement on Tuesday, saying he was "wasn't comfortable" with the backlash that followed the appointment of Orson Scott Card as writer.Superman fans and gay rights groups had criticised DC Comics' decision to hire Card, author of the best-selling Ender's Game books and a fervent critic of gay marriage.Award-winning artist Chris Sprouse's decision to pull out will set back Card's inclusion in what was set to be a high profile addition to the Adventures of Superman series. "It took a lot of thought to come to this conclusion, but I've decided to step back as the artist on this story," Sprouse said in a statement released Tuesday. "The media surrounding this story reached the point where it

took away from the
actual work, and that's something I wasn't comfortable with.
My relationship with DC Comics remains as strong as ever and I look forward to my next project with them."Card
is a board member of the National Organisation for Marriage, a group at the forefront of the fight against same-sex marriage in the US. He has called being gay "a reproductive dysfunction" and once suggested people would rise up and overthrow any government that supported gay marriage. His appointment led to threats of
boycotts by some fans and comic shops and an online petition against the hiring. Michael Hartney, an actor and writer who has been campaigning for DC to drop Card said Sprouse's decision was "amazing news".DC
issued a statement distancing itself from Card's views last month."As content creators we steadfastly support freedom of expression, however the personal views of individuals associated with DC Comics are just that – personal views – and not those of the company

itself," DC said in a statement. Hartney called the statement "cowardly and lame". "They should just drop him. This man campaigns against gay rights.
It's not just about his beliefs, it's that he is trying to push for those beliefs to become public policy.
If he was against inter-racial marriage, DC would never have
hired him," said Hartney.Jono
Jarett of gay fan group Geeks OUT said DC had been targeting the LGBT community and he was disappointed that they were still working with Card: Chris Sprouse

is a talented artist and it's not surprising that he's chosen to distance himself from this radioactive project. It is, however,

surprising that DC continues to stand by Card, whose very public bigotry and anti-gay activism remain
at odds with the publisher's attempts to
engage their fans in the LGBT community.DC
Comics said on Tuesday:
"We
fully support, understand and respect Chris's decision to step back from his Adventures of Superman assignment. Chris is a hugely talented artist, and we're excited to work with him on his next DC Comics project. In the meantime, we will re-solicit the story at a later
date when a new artist is hired."The publisher said it was looking for a
replacement artist.Fans' anger over Card's views are now fat loss factor of the filmed adaptation of his sci-fi novel Ender's Game, which
hits theaters in November and will star Harrison Ford.One studio executive told the Hollywood Reporter that the film'sproduction company Summit should "keep him out of the limelight as much as possible".SupermanComics and graphic novelsUnited StatesGay rightsDominic Rusheguardian.co.uk © 2013 Guardian News and Media Limited or its affiliated companies.

When exercise stresses you out, a college student and

times and other consumer-focused news from The New York Times.
Now consider a program to install a light-rail system — a move that could help relieve highway congestion,
expand commuting choices, reinvigorate urban centers, and more.
You know that getting voter approval to fund and implement the new light-rail line will be
difficult.
According to the MIT assessment, you can increase your odds of success by having a referendum that addresses multiple
transportation modes rather than just light rail. But your best bet is to use existing funds to build a demonstration line and then present a referendum to fund future expansion. In Dallas and Salt Lake City, for example, people who initially opposed light-rail construction in their communities saw the success of the initial line elsewhere and subsequently lobbied for an extension into their areas. To improve your chances of winning over voters, you should place your new line on a corridor with many potential riders, avoid delays and cost overruns during construction, and involve the affected community in the design process. General advice for planners What general messages can mayors glean from the work to date? According to Layzer, a critical first step is to know your city. "The part I find fascinating that's not often discussed or researched is all the ways that implementation can fail because you didn't think about some aspect of the target — the entity whose behavior you're trying to influence," she says. One key variable is a city's attitude toward environmental action. San Francisco, Austin, Boulder, and Minneapolis, for example, are thought to have a google sniper 2 ethic, which may contribute to those cities' ability to adopt aggressive
sustainability policies. Indeed, in some cases, environmental ethic may trump other seemingly obvious influences, such as climate. Minneapolis, for instance, has cold, snowy winters and yet is a leader in bicycle programs; when winter comes, the bike-share stations are simply removed until spring.
The propensity to accept or

resist rules may also influence the form of a city's
programs.
New
York, for example, has a culture of rules, fines, and compliance.
In 2009, New York City instituted a rule prohibiting retail establishments that are running air conditioners from propping
their doors open on hot days.
Few stores complied — until the city began
fining stores and issuing warnings, and compliance began to rise.
"If you tried that approach in San Diego or Houston, you
might get a lot more pushback," says Layzer.
In such cities, successful environmental programs are more likely to take the
form

of incentives or education than mandates. In the end, different variables and
city attributes matter for different
kinds of programs — a complicating factor that the MIT teams try to address in their assessments.
"One thing we talk about is that for this policy area, these kinds of city attributes can really matter," says Layzer. "So it may be in the realm of,
say, bike planning, New York can learn from Minneapolis but not from Chattanooga."
And while putting values on such attributes
as environmental ethic may seem subjective, Layzer believes that long-term residents have

a "pretty accurate sense" of their city's culture and what would work and what would not.
Continuing work Layzer and her team are now grappling with how best to present the

assessment information so that people can use it and learn from it.
Her goal is to produce a series of web-based tools that gives the visitor easy access to relevant, action-oriented
analyses incorporating prose, graphics, and links to detailed supporting information. When those tools are
available, she will ask various sustainability organizations to post them so that others can use, refine, and expand them. She is also seeking a means of constantly updating the data so as
to generate new assessments and analyses every few years. Her original concept was to have cities and students collaborate. "Cities have no money, but there are lots of universities with students who want real-world experience," says Layzer. But as her own experience has shown, students have many demands on their time, and progress can be slow — and that is a problem for urban planners.
"Wait

too long and the political moment will have passed," notes Layzer.
She is hoping to speed the process by incorporating methods of automated data collection. "While the time-consuming, labor-intensive interviews would still be necessary, certain types of data could be collected automatically that could tell you a lot about a city," she says. Once she's finished "inventing the method" and others are using and improving
it, she plans to move onto the next piece: determining whether urban programs actually make a difference. It may seem obvious that they would — but perhaps not always. For example, if people get
appliances that
are

more
energy-efficient, they might use them more, causing overall energy use to increase rather than decrease.
Similarly, the energy and environmental gains from requiring new buildings to be
green may be less than predicted if those buildings are not used as
efficiently as possible. Layzer recognizes that establishing a clear link between sustainability programs and measurable environmental
impacts will be tricky. "You have to be clever about what you measure and how you figure out whether it was the program that caused the outcome or not," she says. "It'll be a totally different kind of challenge, but I think it's worth a try." This research was
funded by a seed grant from the MIT
Energy Initiative.
Work continues under a grant from
the Summit Foundation. Further information can be found at papers.ssrn.com/sol3/papers.
