Hot Invention Cools Down Environment

A seemingly banal industrial component is a heat exchanger and they can be ridiculously inefficient. What a heat exchanger does is regulate the temperature of machines that have to be kept cool like an industrial sized-fridge.

At Concordia, a doctoral student has created a new device that can make heat exchangers more efficient and thus environmentally-friendly. It’s this sort of advancement that is good for the environment and good for profits so I’m sure we’ll see his heat exchanging technology being implemented sooner rather than later.

The innovation behind Vatistas’s unique design comes from over two decades of research into vortex flows. “Growing up in southern costal Greece,” recalls Vatistas, “I became familiar with the concept of vortices at an early age when my elders would warn me of the dangers of swimming near whirlpools!” Youthful fascination evolved into research passion as Vatistas performed advanced theoretical work into how vortices alter the flow of fluid substances like air or water. He later went on to gain international renown for proving Nobel Prize-winner J.J. Thomson’s 125-year-old theorem on the stability of vortex rings.

But it is on the practical side of things where Vatistas’s work resonates loudest. When Vatistas realized that swirling flow could dramatically increase heat transfer exchange, the commercial application of his research quickly became evident. He then partnered with Valéo Management L.P. to investigate new designs of heat exchangers and received a prestigious Idea to Innovation Grant from the Natural Sciences and Engineering Research Council in support of the work.

Life After Death for American Shopping Malls

Malls have lost a lot of their popularity in consumer culture which has caused many malls to close down. This leaves huge swathes of land unoccupied in towns and cities that can be repurposed from something destructive to the environment to something that respects it.

Well, if a mall hasn’t already closed, it can consider one of the new iterations of the contemporary mall. Communities and city planners have gotten creative, using abandoned mall spaces for schools, government offices, medical clinics, casinos, wedding venues, call centers and churches. And while some malls are being torn down and housing or completely new retail buildings are being built, it is much more economically savvy (and green) to reuse the existing infrastructures.

How about an urban farm? While streams and other natural features have been brought back from being buried under concrete in some situations where malls are getting makeovers (along with adding putting greens, dog parks and other outdoor activities), a few enterprising souls have taken a look at the great natural light (many malls were built with skylights), good access to public transportation, and central locations. And thinking green.

Stop Junk Mail by Taking Photos

Nobody likes getting dead trees in their mailbox – particularly when those dead trees are useless adverts for products nobody wants (or even needs). Luck for us PaperKarma has created an app for your mobile that allows you to unsubscribe from junk mail lists by simply taking a photo! For now, it looks like it’s only usable in the USA.

PaperKarma works on magazines, catalogs, coupons, fliers, credit card offers, and even the Yellow Pages. To sign up for the service, you need to hand over a bit of your own information, including your address and email. Once you do, all you need to do is snap a picture of the junk mail in your mailbox and PaperKarma unsubscribes you from the list. The nice thing is that you can pick and choose what you unsubscribe from. If you like getting a particular catalog, you can keep it on your list.

Time + Money ≠ Happiness

Trying to make a decision about your life and how to spend the time you have? Well don’t thinking about spending time, in fact don’t let the idea of money- as-time factor into your decision at all.

Professor DeVoe and PhD student Julian House based their conclusions on three experiments. In each, a sub-group of participants was primed, through survey questions, to think about their time in terms of money. This group subsequently showed greater impatience and lower satisfaction during leisure activities introduced during the experiments. However, they also reported more enjoyment and less impatience when they were paid during one of those activities, which was listening to music.

Why You Should Talk to Yourself

Talking to yourself is a good way to reason through problems, so there’s no reason to feel awkward about your big debates you have with yourself while walking down the street. At least according to some new research from a few universities.

This new research in questions stems from Talk­ing Aloud Part­ner Problem-Solving (TAPPS) which is meant to help people reason through problems while a person just listens. It turns out that the partner’s role is negligible.

In recent research on TAPPS, reported in the Uni­ver­sity of Arkansas pub­li­ca­tion Research Foun­da­tions, Spring 2011, the author noted that the increased speed and effec­tive­ness of part­ner problem-solving has lit­tle to do with the mon­i­tor and much to do with the prob­lem solver’s own behav­ior; think­ing aloud or TA. The con­stant ver­bal­iza­tion of their thoughts out loud encour­aged the prob­lem solvers to con­tin­u­ously cor­rect faulty steps in logic. The causal mech­a­nism of suc­cess was the problem-solver’s metacognition.

Another study on talk­ing aloud reported in the jour­nal Aging, Neu­ropsy­chol­ogy, and Cog­ni­tion car­ries the intrigu­ing title, “How to Gain Eleven IQ Points in Ten Min­utes: Think­ing Aloud Improves Raven’s Matri­ces Per­for­mance in Older Adult.” At the end of the arti­cle, fol­low­ing the usual iden­ti­fi­ca­tion of study lim­i­ta­tions, the authors stated, “Nonethe­less, these stud­ies pro­vide some evi­dence that indi­vid­u­als with lower fluid abil­ity (e.g., chil­dren and older adults) may ben­e­fit most from con­cur­rent verbalization.”
