Then a plate with taken out

Then a plate with taken out apertures to impose on graph paper and on it to count up the area. There was still an opinion - to photograph an aperture (one to one), but it is even more difficult, demands change of a method of opening of heart and a lot of time. All ultram last three ways buy order ultram could be suitable, if valval apertures of heart with firmness gaped, as, for example, a trachea, bronchuses, but they do not gape, and open and closed under the pressure of blood. At a stopping. hearts and circulations of movement of valves stop, and if thus there is considerably any aperture it mismatches the valid disclosing of valves at heart activity. At strong stenoses of an aperture can gape, but also in these cases ultram at warm reductions and pressure of blood , and so, and the area can change. Summing up , it is necessary to recognise, that degree of possible disclosing of valval apertures of heart, their passableness and aperture perimetre at defects of valves can be defined most authentically only a palpation, touch in advance measured fingers ultram of the researcher. For this purpose we develop a method and the formula allowing approximately to calculate the area of valval apertures of heart in square centimetres is deduced. To measure a circle of the fingers it is necessary a soft wire, not rendering on ultram pressure fingers.
Then a wire to develop and measure by its millimetric ruler. It is necessary to measure fingers in three places: 1) on border of a distal and average third ultram of fingernail, 2) on border of an average and proximal third of fingernail and 3) at level of the nail platen. Measurement needs to be repeated some times and to take an average arithmetic. Result of measurement of the fingers: 1) index, 2) an average, 3) the index 146 And an average together, 4) index, average both anonymous together and 5) a little finger to write down and remember. At research by fingers it is necessary to concentrate to touch all attention with the big thoughtfulness and care. If aperture perimetre to accept for a circle order etodolac it is easy to ultram calculate the circle area, instead of the true area of an aperture. Circles possess extreme properties: 1) from all possible closed curves having the given length, a circle of this length limits the greatest area (maximum), and 2) at the set area from all closed curves limiting this area, the circle has the least length (minimum). From ultram this follows, that the circle area always more than the true area of valval apertures and can have only rough value. As valval apertures have no circle form, and are more similar to wrong polygons on perimetre to define their area it is impossible. If them ultram to assimilate to the correct entered polygon the area of the last ultram and will be closest to the true area of the given valval aperture of heart. But also correct polygons as has shown Gauss, it is possible to construct by means of compasses and a ruler only under certain conditions - when the number of the, Where - any whole rational indicator, and pi 2... - various simple ultram numbers of a kind, where 5 - whole rational . Under theory Galois of other correct polygons, except specified Gauss to construct by means of compasses and a ruler it is impossible. So, it is possible to construct the correct entered polygons only at number of their parties 17... Also it is impossible at number of their parties ... From told leaves, that one of six p-squares can be a required polygon: squares disappear. To take polygons with the big number of the parties it is not meaningful, as their perimetre will come nearer more and more to a circleIt is necessary to choose the closest from these six polygons on the area to the given ultram valval aperture of the heart, one perimetre with it. Only then it will be possible on perimetre of the given valval aperture of heart with enough approached accuracy to calculate its area. Abundantly clear, that the area of any correct entered polygon cannot be more areas of the described circle of radius of the same polygon. It cannot be and less areas of the entered circle of the radius peer to an apothem of this polygon. It means, that the perimetre of a required polygon is between two circles limiting the area of a ring. In it all perimetres of all accepted polygons, including ultram required, the closest on the area to the given aperture of heart ultram also are concluded. To approach to the decision of the question, what correct polygon is closest on the area to the given valval aperture, we have made calculations of parametres of all six correct polygons on their perimetre peer to perimetre of a normal mitral orifice, accepted for, under parity formulas in correct polygons (B.N.Delon, L.S.Hrenov, etc.). Results of these calculations are presented to tab. 1. Within this ring also there is the required n-square closest to the area of a mitral orifice of heart. The criterion as for the task in view decision, should be selected an agent average size from the areas of rings of all polygons, and a variation measure - an average square-law deviation () as more exact. The averag ultram e calculated under the formula: Calculation of an average square-law deviation () is made under the formula applied at small number of variants: 1 Length of perimetre of normal valval apertures of heart is taken from A.I.Abrikosova. 148 Table 1 The calculated parametres for a heart mitral ultram orifice at its perimetre of 100 mm under parity formulas in correct polygons It is peer. It allows the area of a 5-square with perimetre 100 mm to consider approximately the equivalent area of a normal mitral orifice. The 5-square area calculated under the formula resulted in tab. 1 where To - length of the party of a 5-square millimetres - there is a size the variable depending on length of perimetre of the given valval aperture of heart, and numerical expression 1,72 there is a constant for a 5-square and number abstract (dimensionless), i.e. Factor.
