A WARMING LIFE JACKET

New liner contains a substance that helps fight heat loss in chilly water.

Sometimes the biggest threat from a boat sinking isn't the accident itself. It's not even the sharks that might be swimming nearby. It's a life-threatening loss of body heat from remaining too long in cold water. Now, a South African teen has invented a heat-producing liner for life jackets. It could help delay injuries or death until a rescue is possible.

Normal body temperature for people is around 37° Celsius (98.6° Fahrenheit). But when the core body temperature falls below 35°C (95°F), people suffer from something called hypothermia. When this occurs, the body doesn't function quite the way it should, says Danielle Mallabone. She is a17-year-old junior at St Teresa's High School in Johannesburg, South Africa.

With mild hypothermia, blood vessels just beneath the skin shrink. This restricts blood flow to to help cut the loss of heat from blood. (As blood cools, it speeds the cooling of internal tissues) . Hypothermia also triggers shivering. Those muscle contractions help generate heat to somewhat boost the body's internal temperature, she notes.

During severe hypothermnia, things get much worse. People become confused and uncoordinated. They also have difficulty speaking. Eventually, major organ systems such as the heart will fail. This can lead to death.

The body's temperature can drop to dangerous levels even in relatively warm water, explains Mallabone. That's why she designed a heat-producing liner for life jackets. Pockets in the liner hold a powdered chemical called calcium oxide, which gives off heat when it gets wet.

That heat-producing, or exothermic, reaction warms the water between the life jacket and someone's body. This might stave off severe hypothermia long enough for a rescue.

Mallabone tested her own invention by jumping into 10˚C (50˚F) water. Each test lasted an hour. The first version of her life jacket liner included only 50 grams of calcium oxide, she notes. «But that amount didn't provide enough heat, and my body temperature dropped to 35˚C after just an hour», she says. So, the next version included 1 kilogram (2.2 pounds) of the heat-producing chemical. In her test using that liner, her body temperature stayed above 36.1˚C. The chemical reaction between calcium oxide and water generates heat slowly. The reaction began producing heat after 5 minutes, Mallabone found. The liner produced the most heat about 25 minutes after the life jacket was first immersed.

The teen presented her findings on May 13 in Phoenix, Ariz., at the Intel International Science and Engineering Fair. The Society for Science & the Public, which created the fair in 1950, still runs the competition (SSP also publishes Science News for Kids.)

Overall, Mallabone's tests suggest there's no risk the jacket liner will explode or heat up so much that it risks causing burns. The reaction also doesn't produce acidic byproducts. And because calcium oxide doesn't react with humidity (water vapour in the air), the liners can be stored for long periods and still work when needed.

REVIEW OF ANIQUA TOURS: HISTORICAL, CULTURAL AND CULINARY EXPERIENCES

11 One of my "occupations" is historical re-enactment , including demonstrations of medieval cookery. I was a little apprehensive of ehat I would find when I was taken to the Taverna Antiqua, but I shouldn't have worried. The owner is really trying to do it right. The decor is good although quirky in placs, try the toilets, and the 15th-century carved arch over the bar is worth a closer look. It was raining, a lot, when we visited, so we sat inside but there is also a small seating area outside, overlooking the main square. The menu has medieval style dishes. Try the game pie. You can also get some artisanial beer or a cup of mead. If you get a chance to chat with the owner, Emanuel, you'll find that he's enthusiastic and knowledgeable. He also speaks pretty good English.

12 Ettore was a kick in the pants. Very humorous, very knowledgeable, and well worth the trip. My wife and I really enjoyed my birthday with Antiqua Tours and Ettore. He picked out to a castle first in the lie ugnt a taxi to his car on the edge of town. We drove us up promptly from our hotel and caught a taxi to his car on the edge of town. We drow out to a castle first in the little town of Sermoneta, I think. Had a glass of Prosecco and Espresso and had a nice tour of the castle. He explained everything about the castle. Then we headed over to Cori for a great wine tasting at a little winery. Then we went into town at a little place for lunch and had a fantastic 3/4 course lunch with wine. We had very good food and he told us more stories. Then we headed over to Nemi for some special strawberry cake and a little walk around this Crater Lake town. Then back to our hotel. He spent an extra 2 hours with us and we could not stop laughing and having fun. Fora fun day spend it with Ettore.

13 We had two separate tours lined up to help us enjoy our last days in Italy. One was a guide to take us through the Borghese Gallery. Rebecca was very knowledgeable and made sure we focused on the most important pieces of the collection. You are kicked out after your 2-hour time slot so having her with us made a huge difference. The next day we had a full day booked with Ettore for the Medieval Towns tour. We enjoyed seeing Sermoneta and its castle, Nemi, the olive agriturismo for lunch and our wine tasting at Marco Carpineti. The history of the castle was very interesting. Learning about the native grapes of the region was wonderful... hopefully, we'll be able to find some of those wines at home!

14 My mother andI recently travelled to Rome and had the great pleasure of having a guided tour with Ettore. We had our tour an hour after we arrived and were a little jetlagged as we wandered down the streets to meet him. Our first stop was a coffee shop that had an amazing frozen slushy coffee drink that immediately woke us up. It was great to hear about the culture and history of Rome as we strolled to each of our stops along the tour. Ettore is quite knowledgeable and we explored different areas of Rome like the Jewish Ghetto that had a great fruit and nut bread that was hands down the best thing I had on the trip. I would highly recommend this tour if you are looking to be introduced to Rome in a non-traditional way. Come hungry!

15 Ettore and Sarah are extremely knowledgeable about all things in Italy - history, food, wine, culture, etc. They know much about both past and present. We could listen to them talk for hours and hours and never get bored. They filled our minds and our hearts on a recent 12-day trip to Rome and the countryside and we haven't stopped talking about them since. We took 3 tours with the team during our stay and recommend them very highly. Their attention to detail and customizing your experience has yet to be matched after several trips to Italy. Thanks!

16 We did two tours with Sarah and Ettore. The first afternoon Ettore took us through the story of Ancient Rome. He is highly knowledgeable as well as being fun to spend time with and was very patient with our two kids (aged 10 and 11) and their endless questions! It was a great way to get in as much of the ancient city and history as possible and he made it very entertaining. The next morning we met up with Sarah for a bit of a foodie tour and to visit some of the squares and fountains of historic Rome. Again, I was impressed with the extent of her knowledge and we spent a very pleasant few hours learning more about the beautiful and fascinating city. We only had a brief time in Rome as we were catching a cruise ship and this was definitely the best way to see and learn as much as we could in that time and thanks to both of them it was fun and relaxing, too. I would highly recommend Antiqua Tours.
