Occasionally, head lice or body lice may be acquired from contact with clothing (such as hats, scarves, coats, etc.) or other personal items (such as bedding or towels) that belong to an infested person. This is the more common mode of transmission for body lice.he three kinds of lice that affect humans include: 1  Pediculus humanus capitis (head lice). 2  Pediculus humanus corporis (body lice). 3  Phthirus pubis (pubic lice or crab lice; also called crabs).
The Arrhenius equation provides a relationship between the rate constant #k# and temperature #T#. The Arrhenius equation is: #k=zpe^(-(Ea)/(RT))# where, #k# is the rate constant, #z# is the collision factor, #p# is the steric factor, #Ea# is the activation energy, #R=8.3245J/(mol.K)# is the ideal gas constant and #T# is the temperature.
In case of a single regressor, fitted by least squares, R 2 is the square of the Pearson product-moment correlation coefficient relating the regressor and the response variable. More generally, R 2 is the square of the correlation between the constructed predictor and the response variable.n this form R 2 is expressed as the ratio of the explained variance (variance of the model's predictions, which is SS reg / n) to the total variance (sample variance of the dependent variable, which is SS tot / n).
