Nail vs Tissue vs Circle

Nails are part of the human body contained or grow at your fingertips. The tissue paper (tissue) is a thin absorbent toilet paper made from pulp. A circle is the set of all points on the field at a distance, called the radius, from a certain point, called the center. Who will win?

Nail

Nails are part of the human body contained or grow at your fingertips. Nails grow from a soft gel-like cells that die, hardened, and then formed when starting to grow from his fingertips. At the base of the nail cuticle serves to protect from dirt. The main function is to protect the finger nails were soft and full of nerves, and heightens the touch. Nails are part of the bone is not a protein.

On the skin under the nail there are many capillaries that have a strong blood supply, causing reddish color. Such as bone and teeth, nails is the hardest part of the body because the water content is very little.

The growth of a fingernail in one week on average from 0.5 to 1.5 mm, four times faster than the growth of toenails. Nail growth is also affected by body heat.

Good nutrition is essential for the growth of nails. Conversely, if malnutrition or anorexia nervosa, growth is very slow and brittle nails.

Tissue

The tissue paper (tissue) is a thin absorbent toilet paper made from pulp. It is usually made with several layers as toilet paper, kitchen paper, napkins or tissues.
Manufacturing

The tissue paper machine is made in a special bin. It is not multi-cylinder drying, as in conventional paper machines, but a single cylinder crepe 4.5-5 m. The cylinder is surrounded by two covers drying, in which the paper is dried in hundredths of seconds at a temperature of 460 ° C.

The areal density of tissue paper is approx. 15-30 g / m² (gsm), but can be as low as 5 g / m². Determining areal density of tissue paper is not trivial due to the crepe-like surface, and is regulated ISO 12625-6 on.
tissue

Among the world's largest producers of tissue paper are SCA (Sweden) and Kimberly-Clark of the United States.

Cirlce

In Euklid geometry, a circle is the set of all points on the field at a distance, called the radius, from a certain point, called the center. The circle is an example of a simple closed curves, dividing the field into the inside and the outside.

Distinguish the circle that is the locus of the points contained within this circumference, that is, the circumference is the circumference of the circle. Girth points are at a distance equal to the radius of the circle center, while the other points of the circle are distance less than the radius.

It can be considered as an ellipse zero eccentricity, or an ellipse whose axle shafts are equal, or foci coincide; or outside an ellipse whose guidelines are at infinity. It can also be described as the section perpendicular to the axis, a conical or cylindrical, or as a regular polygon sides infinite surface, which coincides with the radius apotema.

The intersection of a plane with a spherical surface can be: either the empty set (outer plane); or a single point (tangent plane); or a circle, if the cutting plane through the center, called Ecuador
