On homogeneous, smooth surfaces, the distribution of adhesion forces measured with nanocontacts can be as narrow as 1. 1%. Adhesion force versus humidity curves measured between hydrophilic surfaces can be interpreted by assuming capillary condensation of water into the contact region, which causes a meniscus force. The often observed changes in these dependencies when repeating experiments are interpreted as changes in tip geometry in the 1-10 nm length scale caused by tip wear. No intrinsic statistical process is required to explain it. The slower fluctuations are probably caused by plastic deformation and structural changes in the material at the nanocontact. As a possible simple model, we introduce the two-sphere model with surface roughness. Random noise is due to thermal vibrations and noise in the detection system. All types of dependencies observed can be explained by appropriate and realistic tip shapes. For adhesion forces measured between identical contacts, two kinds of variations were observed: a fast, random noise and slower fluctuations.

|The Children of Holden. The connection between Erickson's Identity Crisis, Salinger's "The Catcher in the Rye," and Teen Angst in Young Adult Fiction Книга по Требованию Nathan S. |
J. D. Salinger' s novel "The Catcher in the Rye" introduced American literature to a new kind of protagonist - the angst ridden teenager stuck in the mire of adolescence. Holden Caulfield was frustrated, cynical, and weary of a society that was full of disappointment. His struggles with school, the opposite sex, and the loss of his brother Allie helped him to become the voice of a generation of teenagers. Out of Holden' s skepticism over his future - "I think I am, but how do I know? " - a new literary genre was created contending with the tumultuousness of adolescence itself.
