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.
The QRS complex is made up of three waves. These waves indicate the changing direction of the electrical stimulus as it passes through the heart's conduction system. The largest wave in the QRS complex is the R wave. As you can see from the diagram, the R wave represents the electrical stimulus as it passes through the main portion of the ventricular walls. The wall of the ventricles are very thick due to the amount of work they have to do and, consequently, more voltage is required.
