Leopards

Leopard

The leopard, Panthera pardus, is a member of the Felidae family and the smallest of the four "big cats" in the genus Panthera, the other three being the tiger, lion, and jaguar. The leopard was once distributed across eastern and southern Asia and Africa, from Siberia to South Africa, but its range of distribution has decreased radically because of hunting and loss of habitat.


Leopards are agile and stealthy predators. Although smaller than other members of the Panthera genus, they are able to take large prey due to their massive skulls that facilitate powerful jaw muscles. Head and body length is usually between 90 and 165 cm. The tail reaches 60 to 110 cm long, around the same length as the tiger's tail and relatively the longest tail in the Panthera genus (though snow leopards and the much smaller marbled cats are relatively longer tailed)

Leopard has short feet
long body

Leopards show a great diversity in coat color and rosette patterns. Their rosettes are circular in East Africa but tend to be squarer in southern Africa and larger in Asian populations. Their yellow coat tends to be more pale and cream colored in desert populations, more gray in colder climates, and of a darker golden hue in rainforest habitats. Overall, the fur under the belly tends to be lighter coloured and of a softer, downy type. Solid black spots in place of open rosettes are generally seen along the face, limbs and underbelly.

Leopards may sometimes be confused with two other large spotted cats, the cheetah, with which it may co-exist in Africa, and the jaguar, a neotropical species that it does not naturally co-exist with. However, the patterns of spots in each are different: the cheetah has simple black spots, evenly spread; the jaguar has small spots inside the polygonal rosettes; while the leopard normally has rounder, smaller rosettes than those of the jaguar. The cheetah has longer legs and a thinner build that makes it look more streamlined and taller but less powerfully built than the leopard. The jaguar is more similar in build to the leopard but is generally larger in size and has a more muscular, bulky appearance.

The beginning of Simple Celavia

I'm gonna tell about how this blog created. One day, my teacher ask the student in my class, "who doesn't has a blog, raise your hand" no one raise their hand. that meant every student in my class have a blog. but i think it's only me that felt woried about it, because i forgot the password of my previous blog. then, i take the computer beside me and try to log in to my account. but in the end, it fail. my friend suggest to me, just click 'forgot password' when signing in to my blog account. shortly afterwards, the password has sent to my e-mail. i felt pretty relieved. but i didn't realised that there are more problems.

i forgot my e-mail password! damn lol. it fruiteless. i went back to my blog account and once again tried to enter the password i knew. but it still doesn't works. finally, my friend suggest to me, just make a new blog account. but i still wan't to use my old blog. but oh well, i didn't have any other option. finally, i make my new blog account, and a new blog. i'm pretty confused about what the name should be. because the time is short, i decided to name my blog 'rainy days'

when i arrived at home, i turn on my computer, log in to my account and start designing my blog. i design it with a blue-lite header, and a background with lots of teardrops. and also, some of raining widgets. i felt happy with my new blog. but when i realise that there are one of my friend using the same background as me, i start to change all of it. i change the header into a tiger picture, and the background into autumn leaves. and even  i add autumn leafs falling widget.


shortly afterwards, i felt bored to my blog. and finally, i change my design to as you can see right now, and the name into, Simple Celavia. do you know where i got 'simple celavia' name? it's from my Pencil case! :D

What is Aerodynamic?

Example of aerodynamic car

It's unpleasant to think about, but imagine what would happen if you drove your car into a brick wall at­ 65 miles per hour (104.6 kilometers per hour). Metal would twist and tear. Glass would shatter. Airbags would burst forth to protect you. But even with all the advancements in safety we have on our modern automobiles, this would likely be a tough accident to walk away from. A car simply isn't designed to go through a brick wall.But there is another type of "wall" that cars are designed to move through, and have been for a long time -- the wall of air that pushes against a vehicle at high speeds.

Most of us don't think of air or wind as a wall. At low speeds and on days when it's not very windy outside, it's hard to notice the way air interacts with our vehicles. But at high speeds, and on exceptionally windy days, air resistance (the forces acted upon a moving object by the air -- also defined as drag) has­ a tremendous effect on the way a car accelerates, handles and achieves fuel mileage.This where the science of aerodynamics comes into play.

Aerodynamics is the study of forces and the resulting motion of objects through the air [source: NASA]. For several decades, cars have been designed with aerodynamics in mind, and carmakers have come up with a variety of innovations that make cutting through that "wall" of air easier and less of an impact on daily driving.Essentially, having a car designed with airflow in mind means it has less difficulty accelerating and can achieve better fuel economy numbers because the engine doesn't have to work nearly as hard to push the car through the wall of air.
