An example of the use of calculus in mechanics is Newton's second law of motion: historically stated it expressly uses the term rate of change which refers to the derivative saying The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction.
Symptoms of conjunctivitis can include. 1  Pink or red color in the white of the eye(s) (often one eye for bacterial and often both eyes for viral or allergic conjunctivitis). 2  Swelling of the conjunctiva (the thin layer that lines the white part of the eye and the inside of the eyelid) and/or eyelids. 3  Increased tearing.
Streptococcal disease is most often a respiratory infection (pharyngitis or tonsillitis) or a skin infection (pyoderma). Some strains of streptococci show a predilection for the respiratory tract; others, for the skin. Generally, streptococcal isolates from the pharynx and respiratory tract do not cause skin infections. Figure 3 describes the pathogenesis of S. pyogenes infections. S. pyogenes is the leading cause of uncomplicated bacterial pharyngitis and tonsillitis commonly referred to a strep throat. Other respiratory infections include sinusitis, otitis, and pneumonia.
