Angle of Impact. The length of the blood stain is the hypotenuse while the width is the opposite side of the angle of impact. The angle of impact can be calculated from the measurement of the opposite side which is the width and the length is hypotenuse of the blood stain.The angle of impact can be calculated using the formula.The point of convergence of all the blood spatters can be located by drawing an extended line and locate the point of intersection of all the lines. A string can be pinned on each blood spot and raise it following its angle of impact.he angle of impact can be calculated from the measurement of the opposite side which is the width and the length is hypotenuse of the blood stain. The angle of impact can be calculated using the formula.
In chemistry, an oligomer (/ÉËlÉªÉ¡ÉmÉr/ ( listen)[2]) (oligo-, a few + -mer, parts) is a molecular complex that consists of a few monomer units, in contrast to a polymer, where the number of monomers is, in principle, unlimited.[3] Dimers, trimers, and tetramers are, for instance, oligomers composed of two, three and four monomers, respectively. In the context of biochemistry, an oligomer usually refers to a macromolecular complex formed by non-covalent bonding of a few macromolecules like proteins or nucleic acids.
Chiral Stereoisomers. The cis/trans or E / Z isomers formed by alkenes aren't the only example of stereoisomers. To understand the second example of stereoisomers, it might be useful to start by considering a pair of hands.For all practical purposes, they contain the same substituents four fingers and one thumb on each hand.ne enantiomer of these chiral compounds is dextrorotatory; the other is levorotatory. To decide whether a compound should be optically active, we look for evidence that the molecules are chiral. The instrument with which optically active compounds are studied is a polarimeter, shown in the figure below.
