Direct Stresses in Cylindrical Shells,on that through every point of the cylinder one may pass a straight line which lies entirely on this surface. These lines are called the generators. For convenience of language we shall assume here that the generators are horizontal. All planes which are normal to the generators intersect the cylind

Wilhelm Flüggetries. The term “peptone” was first introduced in 1880 by Nagelli for growing bacterial cultures. However, later it was discovered that peptones derived from the partial digestion of proteins would furnish organic nitrogen in readily available form. Ever since, p- tones, which are commonly known as
