Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [ 2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [ 3]
Following the Civil War, it was the last state to be restored to the Union, on July 15, 1870.

The earliest version of the CRT was known as the "Braun tube", invented by the German physicist Ferdinand Braun in 1897. [13] It was a cold-cathode diode, a modification of the Crookes tube with a phosphor-coated screen. Braun was the first to conceive the use of a CRT as a display device. [14] The Braun tube became the foundation of 20th ...

A Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s. By Carnot's theorem, it provides an upper limit on the efficiency of any classical thermodynamic engine during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference through ...
Gravity data suggests that Ceres has a mean dimensionless moment of inertia (I/MR 2) value of about 0.37 indicating some amount of internal differentiation [5] [23] (a spherical body with a uniform density throughout has a moment of inertia of 0.40 while a body whose mass is mostly concentrated near the center has a moment of inertia closer to ...
