What Is a Duvet Cover? Duvet Vs Comforter - a Guide to Bedding

A duvet is typically made from cloth that is sewn to create a large bag and is usually filled with down or other types of soft materials. This is typically used as the top layer on a bed to help keep you warm at night. Duvet came from the French word for down, which is the most used material for filling a duvet. There are other options available, too, such as feathers and wool, as well as synthetic materials, just to name a few. The insert is usually white in color so it will not appear through the duvet cover.

How do i convince my parents to get me a parrot?

Just wait until you get old enough to move out and buy one. It's not really the responsibility factor about a parrot (it plays a big part) but the fact that everyone who lives in your house will be impacted by a parrot, and if they did not really want a bird in the first place then they wo not view your pet very well, and possibly make you get rid of it. Parrots are loud. Birds are loud in general, actually. My birds start chirping as early as 6:20 in the morning. Your whole family will hear it, and if they never even wanted a parrot, why should they tolerate yours? And parrots are also very, very messy. They like flinging their food around or splashing in their water dishes or throwing food in the water dishes. Everything around the cage will end up getting seed on it, and probably some bird feces and feathers too. It's just a thing about birds that you have to live with. Everyone in your house will be impacted by it, and it's not really fair to them to have a pet that they did not even want you to have screeching in the mornings and waking them up. And as far as the cost? Um, 'parrot' is as general of a term as saying 'songbird'. There are HUNDREDS of different types of parrots. Parakeets, budgies, conures, parrotlets, caiques, cockatoos, cockatiels, lories and lorikeets, macaws, Senegals, Grays...tons and tons. And all of them highly vary in price and their care requirements. A cockatoo costs MUCH more than a budgie, not only in the initial cost of the bird but the toys and food they go through and the difference in cage size. So please be more specific

Do birds have nose hair?

They do not have feathers inside their nose. Some (e.g., crows and amazon parrots) do have feathers just outside it, though. In your own nose, visible hairs filter out only the largest particles. After that, the air flow is routed over structures covered with mucus and cilia which catch smaller particles. Birds have similar structures, cilia, and mucus.

what tool is used to measure mass?

A weighing scale is a measuring instrument for determining the weight or mass of an object. A spring scale measures weight by the distance a spring deflects under its load. A balance compares the torque on the arm due to the sample weight to the torque on the arm due to a standard reference weight using a horizontal lever. Balances are different from scales, in that a balance measures mass (or more specifically gravitational mass), whereas a scale measures weight (or more specifically, either the tension or compression force of constraint provided by the scale). Weighing scales are used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight. Specialized medical scales and bathroom scales are used to measure the body weight of human beings.

Where do I put feathers in my hair?

put them where ever u think looks best but i like them right behind ur ear at the top of ur hairline

How many feathers does it take to crush someone?

It sounds like the sort of thing you would have to research in depth. This is the sort of the thing they do on Myth Busters. You would need to know the average weight and size of the feathers to be used. Calculate a mass by volume for the feathers. The crush capacity of a human body. What percentage of the body needs to be crushed to meet the criteria of the human body being deemed crushed. Will the feathers be dropped from a height or slowly distributed onto the body. This data might help you... Biomechanical injury tolerance levels: (This is used more for determining resistance to a force, but would apply to crush weight capacity as well); Its more for the area around the head and upper body, but I am sure you could locate this data with some effort for the bone structure of the arms, legs, pelvic and spinal structure... Throat- 300 lbs of force Frontal bone ( forehaed)- 1900 lbs Back of head ( occiptal)- 2100 lbs Temporal - 1400 lbs Zygomatic-800 lbs mandible - 800 lbs maxilla - 500 lbs Lat. Maxilla - 700 lbs "nasal bone"- 200 lbs Cervical vertebra - 500 lbs Crown of head - 1350 lbs area above the ear - 650 lbs sternum with 4" defelction ( penetration) - 960 lbs ribs - 400 lbs ( 1-3 ribs are the hardest, 4-9 the most common to fracture) Edit: Well, using your data for feather weight, and assuming the occipital bone to be the strongest at 2100 lbs crush capacity, You would need 1, 680,000 feathers. That amount though needs to be applied directly to that bone though, so the amount of feathers is increased. I am not sure how you would calculate the amount of Feathers needed though to crush the entire body (depends on size of the person). I would gowith what someone else suggested, using a cone shape to calculate it. The volume V of any conic solid is one third the area of the base b times the height h (the perpendicular distance from the base to the apex). I assume the base to be large enough to accomodate the height of the person lying down at 1/4 of the height of the cone. The center of mass of a conic solid is at 1/4 of the height on the axis. So you would need to calculate the height based on achieving a center of mass for the cone equal to the weight of 1,680,000 feathers or 2100 lbs and from there, divide the weight of the cone of feathers, by the weight of a singular feather (.00125) and you would have your answer.
