What are Skates Made Out Of?

Skates are basically comprised of the following parts: a boot, a frame, wheels, bearings, and brakes. The boot is the part worn on the skater’s foot. This is then sewn to the frame holding the wheels. Wheels are able to rotate as they go around an axle with the help of bearings. The brakes are also connected to the frame.

There are various kinds of skates, each used for a specific type of skating (inline hockey, aggressive skating, artistic inline skating, and speed skating). Each kind also differs in the material used for their parts.

Boots

Most skates have high boots. These offer a lot of support for the ankles, making it easier to skate, which is usually why beginners prefer this type. For advanced speed skaters, boots made of carbon fiber are more preferable. These allow for a higher level of support. The boots have a low cut to give the ankle room to flex.

Skating casually or recreationally can use softer boots for the sake of comfort. Harder boots are better for more disciplined use. The harder the boot is, the more control and protection the feet get from impact. Finally, skating downhill can benefit from boots which have been molded in heat. These follow the shape of the skater’s foot, giving more precision and control.

Boots are manufactured with padding that offers comfort and shock absorbency.

Frames

The common skates – those used for recreation – have frames made of high-grade plastic (polyurethane). The skates found in toy stores and department stores have lower quality, and are made of low-end types of plastic. Frames used for speed skating are either made of extruded aluminum, pressed aluminum, carbon fiber, or magnesium.

Generally, frames made from carbon fiber are costlier but offer better flexibility. This allows the user to enjoy a smoother ride. However, the transfer of power between the wheels and the legs can be compromised. Extruded aluminum frames, on the other hand, are very solid but are more expensive.

Wheels

These days, virtually every skate wheel is comprised of polyurethane. This type of plastic is quite durable. Other forms of rubber or plastics are faster to be worn out and don’t roll as smoothly. The rule is: the larger the wheels, the higher the skating speed. Bigger wheels, however, require a lot more effort and energy for them to roll. This means that smaller wheels can give quicker acceleration, better maneuverability, and a much lower center of gravity.

During the earlier 2000s, there were substantial improvements in urethane compounds. These allowed skates to use tougher compounds for improved wheel longevity. These also paved the way for the lowest rolling resistance to date. Today, the profile and thickness of skate wheels vary depending on their application and use.

Heel Brakes / Toe Stops

Rubber brakes are connected to the frame’s heel. These let skaters stop at any point by lifting their skates’ toes. This forces a ground break. It is very important to learn how to use the brake, especially for beginners, downhill skaters, and during emergencies.

There are many parts that comprise skates. Each part is made of various materials, depending on the quality and type of skate. Each type corresponds to a different application, allowing various skaters to have a wide range of options available for their every need.

Electronic invoicing

The dematerialization is the transformation of material information carriers (often paper documents) in computer files (which can lead to implementation of the famous “paperless office” in a company).

Dematerialize computer , means transferring to a digital medium of information that exist in analogue form (paper, film, microfilm).

The dematerialization can be used to manage fully electronic way of data or documents that pass within companies and / or as part of exchanges with partners (governments, customers, suppliers, …)

How To Fortify Your Home Against Zombie Attacks

The secret to a strong fortified home is layered defense. The main goal is to keep the attackers as out of reach as much as possible. A classic example of a structure that uses this strategy is a medieval castle. Don’t worry because digging a moat is not necessary in order to survive a zombie apocalypse. All you need is a fortified home, zombie weapons and gear, enough food supply and other essentials.

Medieval castles aren’t built with huge surrounding stone walls for no reason. Those walls were meant to slow down attackers in order to have a better chance of getting rid of them. Turn your simple home into a strong fortress and you’ll have very little to worry about during the attack of the undead. The following tips will tell you how to fortify your home and build layers of defenses from the outside in.

fortress

Starting from the outermost layer, this layer should be a strong wall that can withstand a force similar to a hurricane. Zombies don’t get tired and they can punch and attack this wall forever if they have to that’s why the outermost wall must be the strongest. Install some trip wires and traps that can alert you about the activities or presence of anyone outside. Dig some ditches and trenches for these can slow down the undead. Cameras installed around the perimeter will help in locating the attackers. This makes it easier to know where to focus your weapons and artillery or explosives.

If cameras are a no-go, then an observation tower would be the next good choice. Build this inside the walls and it should be tall enough so you can see around your home. Set up a sniper deck and easily shoot the zombie attackers and they wouldn’t even know what they are encountering or where it is coming from. This is a good vantage point where you can keep a lookout for incoming groups.

fort home

Another necessary line of defense for your fortress are metal coverings for your doors and windows. Wood can also be used to board them up but note that it can easily breakdown. However, it can be reinforced with metal bars to make sure the attackers will be kept outside of your home. Cover the doors and windows from the inside, not from the outside because a horde of zombies can easily rip them out. If you have the budget for it, an alarm system that can alert you if anyone is at the doors or windows will come in very handy.

Your last line of defense are weapons and traps. Sound diversions will be useful in case of a perimeter breech. Install speakers and traps around your perimeter wall and play loud noises to distract and lure out the zombies. As a last line of defense, your weapons must be of high importance. Firearms are excellent but you have to have a huge supply of ammo. Blades, swords and metal rods with sharp objects at its end similar to a scythe will also come in handy.…
