In a clinical study conducted the sensitivity of the MTB/RIF test on just 1 sputum sample was 92.2% for culture-positive TB; 98.2% for smear+ and culture-positive cases; and 72.5% for smear-negative, culture-positive cases, with a specificity of 99.2%. Sensitivity and higher specificity were slightly higher when 3 samples were tested. [10]
Analysis of Mycobacterium tuberculosis via scanning electron microscope shows the bacteria are 2.71 ± 1.05 μm in length with an average diameter of 0.345 ± 0.029 μm. [15] The outer membrane and plasma membrane surface areas were measured to be 3.04 ± 1.33 µm 2 and 2.67 ± 1.19 µm 2, respectively.
For set representing all notes of a major triad: [1 5 ⁄ 4 3 ⁄ 2] the LCD is 4 therefore T = 4 ⁄ f. For set representing all notes of a minor triad: [1 6 ⁄ 5 3 ⁄ 2] the LCD is 10 therefore T = 10 ⁄ f. If no least common denominator exists, for instance if one of the above elements were irrational, then the wave would not be periodic. [4]
[1] [2] A Euclidean graph is uniformly discrete if there is a minimal distance between any two vertices. Periodic graphs are closely related to tessellations of space (or honeycombs) and the geometry of their symmetry groups , hence to geometric group theory , as well as to discrete geometry and the theory of polytopes , and similar areas.
In mathematics, specifically algebraic geometry, a period or algebraic period [1] is a complex number that can be expressed as an integral of an algebraic function over an algebraic domain. The periods are a class of numbers which includes, alongside the algebraic numbers, many well known mathematical constants such as the number π .
Road racing bicycle forks have an offset of 40–50 mm (1.6–2.0 in). [7] The offset may be implemented by curving the forks, adding a perpendicular tab at their lower ends, offsetting the fork blade sockets of the fork crown ahead of the steerer, or by mounting the forks into the crown at an angle to the steer tube.
Oxygen (1s 2 2s 2 2p 4), fluorine (1s 2 2s 2 2p 5), and neon (1s 2 2s 2 2p 6) then complete the already singly filled 2p orbitals; the last of these fills the second shell completely. [ 39 ] [ 58 ] Starting from element 11, sodium , the second shell is full, making the second shell a core shell for this and all heavier elements.
