One of the most attractive pet rabbit. It is nice and sweet and perfect for those low key kind of animal that wants to own a home. You do not need too much energy to move on your part to support their needs. As a rabbit, but it does mean that you are responsible for taking good care of her. Here are some tips to help you can care for your pet rabbit.
First, it is checked by your veterinarian before going home. This is important, especially if you have small children at home. At the same time, if you do, you’ll know if the rabbit is healthy or not. Better to know in order to know the health of your pet, for example, to take care of him. You can ask your vet for advice on how to ensure adequate food for your pet.
Rabbits are herbivores. This means that they eat plants. There are different kinds of fruits and vegetables for your pet rabbit to keep. You can also see, as they can eat grass. You can also enter the granules. Pet stores sell these, just ask the right kind of granules with the age of the animal. Do not forget to take a cup of water for them, as rabbits can be very thirsty.
Unlike cats or dogs, rabbits prefer to have their own paradise. Rabbit cells are similar to rabbits developed habitat. This is the perfect home for rabbits, as they make their own space, such as. It is better to sleep in his room to eat and do other things without being distracted. It is important that the pen near the house and clean everything.
Like all other animal species, rabbits need exercise, too. Let loose in the back yard, but make sure that the first point of closure, so that they can not escape. You can also enjoy the rabbit toy for them.
Here are some tips you can try if you can have a rabbit. Remember that your job is to care for your pet, and it is important that you properly. You do not need to spend too much money to care for your pet rabbit, because you can be cheap for them things. Ask your friends or your veterinarian.

Inspired It’s amazing how many of our modern technology is used by mother nature, which means that human invention, innovation, and our new concept inspired by what we see in our natural environment. It does not matter if the computer tech, transportation, or even our cars and our military tech, everything seems to start from what we see. Consider an airplane, if you will, the concept of humanity is likely to fly from birds came, and it was only a matter of time before the right materials and put them together properly in the right elevator possible. Okay, so I mentioned military technology and you can not believe that an army tank of bio-inspired design. If you are a turtle, you can see, punctuated by heavy armor shell where it goes. The same goes for many mussels and crabs have an exoskeleton body armor. One of the best designs for Mother Nature can be an animal, the armadillo will be. Of course the shield is fairly sturdy and can protect against predators and enemies. It’s amazing the kind of problems that evolution can solve. It is also interesting to see how humanity can do what he observed, and by imitating those who turn ideas into useful objects, are the biggest challenges to solve. Well, guess what Leonardo had in mind when he developed self-propelled round tanks in a position to fire in all directions? He was inspired by a grenade, or a marine animal that had a grenade? Not so long ago, in the Wall Street Journal had a very funny cartoons. In the animated series two turtles wander through the desert, and they sat on a sand dune watching an army tank to continue. Mankind has only a marginal improvement on the ongoing developments “billions of years of development. If you have any other military technology ideas, inventions, innovations and / or ideas, please e-mail me at your earliest possible convenience.

The friction or drag force, is used to analyze and determine the potential movement between the contact surfaces of two bodies. In particular, the force that resists the movement, and consists of various types. The guy who people are probably familiar with dry friction is called – in contrast to fluid friction, the friction of the skin and internal friction. Dry friction is divided into static friction and kinetic friction.
Static friction and kinetic friction
The name pretty much says it all, but here is a basic overview for good measure. Static friction is the frictional force that opposes motion between the permanent members, or organizations that do not move to another. The force of friction between the tire and rubber flooring that allows a vehicle to accelerate is a good example of static friction.
This can be confused with the kinetic friction due to the fact that the tires and vehicles are in motion. However, due to the special section of rubber in contact with the ground is stationary relative to the ground, is the static friction. If not for the force of static friction, the vehicle would not be able to accelerate – at least not quickly.
A good example of kinetic friction is when you press the brake when traveling at high speed, lock the wheels to skid on the road. From the point of the rubber tire begins to slip is the point of releasing the brakes or make a complete stop, experience kinetic friction.
The coefficient of friction and traction COF
Traction is another way of describing the maximum static friction before the move or slip. However, to determine the coefficient of static friction drive (COF) between the two bodies in question is necessary.
The friction coefficient is the ratio of the friction force between two bodies and the normal force or the force that is pushing them together – equal to the weight force of the upper of the two bodies. There are two types of friction: the coefficient of static friction and kinetic friction. The coefficient of static friction is generally greater than kinetic friction.
The two solid COF can also vary considerably depending on friction or dry friction call is lubricated – a form of fluid friction. This may seem obvious, but there are some materials that COF remains the same regardless of the presence or absence of lubricant, such as steel on steel and polyethylene to Teflon.
The laws of the three laws of dry friction and Amontons “first and second friction
Amontons First Law “:” The friction force is directly proportional to the applied load. “For example, doubling the load of the friction force will also double – increases or decreases proportionately.
Amontons Second Law “:” The friction force is independent of the apparent surface of contact. Flat “areas like the face of a brick or smooth sheet steel, are just shots from the nerve endings in your fingers can detect.
All surfaces to form a row of peaks and valleys seen in the microscope, the peak height, which are determined by the type of material.
According to the law Amontons First, these peaks will be crushed or bent in proportion to the normal force, causing more or less at the peaks of friction contact. But if you extend a certain weight in a wider area, all they do is to reduce weight at any time under the pressure equation P = F / A, P pressure, F for force, and region.
The force is constant as the weight of the object in question does not change, meaning that changes in the surface, the pressure must also change with an inverse proportion. This means that less material will actually be in contact per unit area. This results in a lump sum equal to the force of friction the same weight and power, demonstrating the second law of Amontons. ”
Rubber tires and the second law of Amontons ”
Well, what about rubber tires? Good question. Amontons The second law “is an idealization which is more or less rigid and elastic. Traction apparent upper size tires can be attributed to the fact that the rubber is actually relatively slight elastic deformation to accommodate the geometry of the different soil conditions, and therefore be considered as an exception to this law. The most friction forces often provide elasticity is negligible compared with the amount of COF tape defined by the material. – Because the wider tires to compensate for the wear rate faster with more rubber COF distributing weight over a larger area! Contrary to popular belief, is the main reason for wider tires, not the width, in itself, provides more traction. For most practical purposes, the second law of Amontons “still stands.
Coulomb law of friction “dynamic friction is independent of sliding speed.” It’s simple and simply says that the rate at which two bodies move in relation to another is irrelevant in determining the kinetic friction force.

One of the problems in the manufacturing sector has always been safety. The future looks OSHA in the United States? Like other nations, without the safety of workers, before starting on the world market, they will come in its industrial revolution, like America. But as long as they continue to pollute air and water and take advantage of cheap labor.
The United States should relax their standards and OSHA agreed with reality. Some say that any relaxation of these rules will be deceived and careless and clearly against the American worker, to increase profits and exploitation of our labor markets at home.
With the advent of new materials such as sheets of carbon nanotubes will be used by other methods, such as the use of radio-frequency field in a microwave oven, ionic chemicals and large amounts of heat. Robots can be used for such tasks, but the frequency of contamination of the workplace can be very damaging to human bio-and medical services. This can lead to free radicals, cancer or other diseases. Although these are not enough, it is important to explore different methods are introduced for the production of carbon nanotubes.
The scheme of each method should be evaluated to prevent contamination of the bi-products released into the environment or in an area where they can enter the human bio-system. Because of the peculiarities of working with such small dimensions, it may be a set of detailed procedures, which will be introduced in production of carbon nanotubes is feasible and safe.
While the industry tries to answer these questions and suggest appropriate protocols relate to something, should not repeat the problem of asbestos, which caused chaos and cost many lives changed. Filter Design, which can protect us will be difficult due to the micro scale, we will work, however, there are ways to maintain control of the particles during the process. Then we need to handle a much higher level, if we can mass-produce high performance and security for all carbon nanotubes have many applications.

Solar cycles of the sun and solar flares on the color bands of gaseous planets? It may be my theory. Take, for example, Jupiter is the largest planet of the gas in the Gaza Strip, and the gas flows from the weather. And we know that suffering that the weather on earth from the sun as the planet warms.
An interesting article on this subject can be found in everyday space (point) can be found under the heading: “Stripes returned to the season of Jupiter”, published 24th November 2010 and written by its editor-JPL in Pasadena, California. L article said. “Every few decades or more, the South Equatorial Belt is quite white, perhaps 1-3 years, an event that scientists puzzled for decades to radically alter the appearance is seen only with the equatorial belt South that does this is unique to Jupiter and the solar system. ”
The signs of the last solar cycle maximum the Sun is the reason why we see the emergence of some categories of gas in Jupiter, we have not seen for years? I do not think we should be surprised at all, really, it’s very significant. There was no real research on this issue, but maybe the scientists agree with me. You can do it yourself suggested, as it is to ask an obvious question for astronomers and cosmologists.
There is ample evidence that, of course, but not enough evidence to prove it. Perhaps for this reason that the brain is removed, it is working invited to ask this question formally. In fact, I led the group the next day and decided to not have enough information to answer this question, but perhaps you may have some thoughts on the subject. At the same time, I hope, please consider this.
