Tights come in thin and thick options. Thinner tights are called sheer and thicker ones are called opaque. People measure this thickness uses something called "denier". They are five categories that show what denier a pair of tights is: Ultra sheer, sheer, semi-opaque, opaque and thick-opaque.
Tights are intended to maintain a wearer’s legs warm, and they arrive in a vast collection of colors, lengths, and materials. Tights come in a diverse selection of colors and patterns. 1 rule of thumb to consider is that coated leggings like the shiny metallic leggings will usually have less stretch than faux leather leggings or even our basic nylon leggings which are the absolute most easy to fit due to their unhindered stretch.
Cockatiel
Cockatiels are small birds originally from Australia and are related to many other cockatoos. They are the second most common bird species kept as a pet. Cockatiels can live from 10 to 25 years, depending on how healthy their lifestyle is, although wild cockatiels usually live shorter.
Cockatiels have tiny feathers on their head called a crest. The crest allows the owner to have an idea of what they are feeling; straight up if scared or excited, flat when they're angry, and slightly curved is normal/happy.
In the wild, cockatiels are prey animals, meaning there are predators that eat them. As a result, cockatiels can scare easily, especially when they meet someone or something they do not know. With enough patience and affection, an owner can tame the cockatiel and help them get over their natural fear. Like many other parrots, cockatiels are very good at climbing, and use their beak to position themselves each time.
Cockatiels come in many different colours, some naturally while others were specifically bred. Gray is considered to be their original colour, and is one of the most popular, along with Lutino (yellow). Males have a brighter crest and face, and sing louder and more frequently than females. A cockatiel has very long tail feathers compared to other birds.
Seeds make up most of their diet, but veterinarians strongly recommend various fruits, vegetables, and beans as well. However, a few of these may be harmful to them, and it is advised to be cautious with what they eat. It can be very hard to get adults to try new foods, so it is best to have them try little by little at a time instead of all at once.
Like other birds, they can be taught to do many tricks; including flips, handshakes, fly-on-command, showing their wings, and more. Patience and repetition is key, as teaching one trick can take many months. They can also be taught to sing, but may become confused and ruin the song if it's too complex.
Cockatiels are social birds, and like to spend time with others. They can become overly attached to their owners over time (especially if raised young), and may start to shriek when they feel lonely. If the owner is unable to spend a lot of time with them, getting them a partner (preferably another cockatiel) can help resolve their clinginess.
Cockatiels are Australian psittacines native to the deserts (Forshaw, 2010).
They are genetically adapted to high temperatures, amid centuries of domestication

North Hollywood shootout
The North Hollywood shootout was a gunfight that happened on February 28, 1997. Emil Matasareanu (July 19, 1966 - February 28, 1997) and Larry Eugene Phillips Jr. (September 20, 1970 - February 28, 1997) were bank robbers, and used AK-47s, an AR-15, an HK-91, and 9 MM pistols. The police could not easily kill them because of their heavy body armor, which was made out of kevlar. 20 people were wounded, and the only two killed were the robbers.
Matasareanu was shot dead by police. Phillips shot himself in the head with a Beretta M92F as police shot him multiple times. His body was left in the street for about an hour before ambulances came to take his body away.
AR-15
The AR-15 is a semi-automatic rifle designed by the ArmaLite Division of the Farichild Enginer and Aircraft Corporation in 1958 by Eugene Stoner. It is the civilian predecessor of the M-16 rifle.
The " AR" in its name reflects the first two letters in the company name... ArmaLite. The fact that the AR-17 is a shotgun gives lie to a common belief that AR stands for "ArmaLite Rifle."
The military version is the M-16, manufactured by Colt Firearms, FNMI, Harrington Richardson, Daewoo, and others.
The AR-15 is a semiautomatic rifle that discharges a single shot with each pull of the trigger until empty. The M-16, unlike the AR-15, is a select fire (semi and fully automatic) magazine fed, gas operated, shoulder fired assault rifle. The M-16 first saw combat in the Vietnam War.
The AR-15 is a lightweight, magazine-fed, air-cooled rifle with a rotating locking bolt actuated by propellant gas expanding within an internal gas piston operating system.
The gas for this system is tapped from the barrel and travels down a gas tube that feeds it into the bolt carrier and thus the gas (i.e. piston) cylinder. The gas expands within the piston cylinder and forces the carrier rearward. A cam pin linking the bolt to unlocking surfaces of the bolt carrier forces the bolt to unlock from the barrel and allows the assembly to drive to the rear.
An error in an early article covering the AR-15 described the system as a "direct impingement" system. This long standing error is based on the fact that a true direct impingement system also moves propellant gasses from the barrel into the face of the carrier. Unlike pressurizing a piston cylinder in the bolt carrier, the gas of the direct impingement system simply passes into a shallow depression in the bolt carrier and actually blows the carrier to the rear.
Early usage of the M16 version of the AR-15 in Viet Nam resulted in intense criticism of poor reliability. On-scene studies revealed that the barrel and chamber tended to accumulate rust pits in the humid conditions in Viet Nam that caused difficult extraction of fired cartridge cases. Chrome plating of the barrels and chambers solved the problem and the M16 has gone on to great approval. While the early AR-15s also were built with un-chromed barrels the moderate climate in the US and gentler use by owners resulted in few problems.
Barrels of current commercial variants of the AR-15 are produced in chromed, un-chromed, and stainless steel barrels with little extraction difficulty in the more moderate climate in the US.
Even the earliest AR-15 and M16 internal piston systems were chromed plated and the rifles performed well if properly lubricated and cleaned. Nonetheless some rifle manufacturers have accused the internal piston system of inferiority and modified the rifles to an external piston system and driving rod pushing the carrier.
Two such designs were developed for the military and found unneeded. Extreme test firing (2000 rounds with no cleaning or lubing and no malfunctions) confirmed findings that simple lubrication keeps the rifles functioning for extreme periods, but all manufacturers recommend more frequent cleaning.
First considered of little use, the AR-15 was long considered to provide inferior accuracy to target shooters in the prestigious Service Rifle matches. The provision of heavier match barrels and target sights by ArmaLite and heavier match bullets by the Sierra Bullet company produced accuracy so satisfactory that they have displaced the previous M1 and M16 rifles used in those matches.
