Do elephants freeze?
When the zoo public – being themselves wrapped up in thick coats, gloves and woolly hats – see the elephants in winter in the outside enclosure, they wonder, whether it's not much too cold for the animals.
However many visitors are not aware that Asian, but also African elephants live at a big height. In their habitats the temperature can easily drop below zero degrees at night. So the home country of the two cow elephants of the zoo of Zurich – Druk and Chhukha – is Bhutan.
Bhutan is a mountainous country at the South declivity of the Eastern Himalayas between China and India.

I have got a reply on webcase that Mac OS X like Lion is not supported in Xilinx ISE any versions. Xilinx seems that they dont know that the world is changing. More users are using Mac machines. Besides, many application notes are still using Win XP. There is still no plan or support on PC driver for Win 7 (for xapp859 and xapp1052).
Does the cold have an effect on the elephants' everyday life?
The zoo in Zurich is located at 609 meters above sea level. That means that the elephants have to live in wintry conditions from the end of November until the end of February.
These climatic conditions have an effect on the elephants' daily routine.
But also at temperatures of below zero degrees, they are let out into the outside enclosure in the morning for the cleaning of the stable. This requires speedy and accurate working from the elephant keepers, because otherwise the elephants could get too cold and they could freeze freeze and fall sick.
Are elephants sensitive to cold?
However the fresh air and the change compared to their living in the stable is good for the animals. It is important that the skin of the elephants is absolutely dry when they are let out from the stable into the wintry outside enclosure. Especially the edges of the ears and the tip of the tail of the elephants are particularly at risk at a severe cold.
When can the elephants not go out anymore?
When it's still very dark and extremely cold (10 degrees below zero) in the morning, the elephants can not be let out into the outside facilities anymore.
After the cleaning of the stable, the elephants are fed with bran.
The morning work in the elephant stable can start.
Because the elephants' skin is wet after the daily washing and bathing, they are not yet let out into the outside enclosure due to the danger of catching a cold. Pastemates overdrive mac os.
What are winter works?
Neither the warm sun, nor the fresh air calls the elephants into the outside enclosure during this time of the year.
There's plenty of time now to care thoroughly for the feet and the nails of all elephants. On this occasion the profile of the sole should not be cut back too much, because otherwise the elephants lose their slip reliability on the stamped snow. Destination: earth mac os. This could lead to dangerous falls.

When do the elephants go out?
After the work there's a snack of branches and hay in the stable. During the midday break, the elephants dry in the heated stable and after that they can be let out into the wintry outside enclosure.
Usually particularly the young elephants get a lot of pleasure out of the snow and the ice chunks. They grasp the unknown white thing or try to eat the snow. However, too much of it is bad for their health and can cause belly-aches and diarrhea.
Do elephants like to be in the snow?

Snow and ice are new elements in the elephants' everyday life.
The snow lets the outside facilities appear completely new and the ice forces the elephants to use a more careful and slower pace.
Fortunately the elephants move on four strong legs with a good grip profile at their feet. Wranglings don't happen so frequently and even the bull adapts his temper to the external circumstances.
After the stable has been cleaned once more and the evening food has been given out, the elephants will gladly return into the warm stable after about one and a half hour.
Here's an idea for PBL that a high school class may enjoy.
Which case would apply more pressure on a floor — an elephant standing on its hind legs or an Olympic figure skater standing on both skates?
The imagery is startling and almost comical — perfect for an inquisitive teenager busy analyzing the surrounding world. Over 10,000 pounds of the largest land animal on Earth balancing itself on its hind legs must certainly press down with more pressure than a mere (approximately) 150 pound-person standing solidly on both skates.
Challenge your students to collaborate in a Google Doc to develop a list of questions they would need to know the answers to in order to solve the final problem. For example:
What is the formula for pressure?
How much does an elephant/figure skater weigh?
What is the bottom surface area of an elephant's foot/skate's blade (which touches the ice)?
Stand back to be available for consultation if needed, but let them work it out. All the information is freely available. Their findings and calculations can be posted in an Edmodo poll and let their peers vote on which answer is correct and reply with arguments supporting or contradicting the calculations. The calculations will be made over and over again as they discover more details about how skate blades are shaped.

They might want to take a field trip to the ice rink to make an impression of their skate blades on a piece of paper or invite a physicist to a Google Hangout to 'visit' the class and discuss the theories offered to explain how skates slide on the ice or design an Algodooexperiment to demonstrate force and pressure.
Students can then express what they've learned in a video (using an app such as Educreations) or a digital story (using an app such as Pixntell) or any of a variety of other formats. Images for the presentation can even be drawn using Skitch or collaboratively in a Google Drawing. This can also be a good opportunity to discuss digital citizenship and an advanced Internet search to find open-source images.
(You might be surprised to know that 10,000 lbs/(8in x 9.5in x 2 feet) equals approximately 21 lbs/sq.in. whereas 150 lbs/(12in x 3/16in x 2 skates) equals approximately 33.3 lbs/sq.in. If we would imagine the figure skater in a pirouette on the tip of a single skate, the pressure shoots up to over 4,000 lbs/sq.in.!)
