Age related changes in accommodative dynamics in humans Dear Editor Using the PowerRefractor, Kasthurirangan and Glasser (2006) conclude that: ''For accommodation, time constant increased and peak velocity decreased with age.'' For subjects less than 40 years of age, I find that the authors' data does not support this conclusion. Examination of the authors' Figs. 5a–c for their subjects of 14.7...

When included in the German language, Anglicisms integrate with grammar system. As it is known, nouns English language have no gender, but if they are accepted German, immediately get grammatical gender which expressed use of an article. In Anglicismzs determined according to following: 1. Biological sex; 2. Lexical similarity; 3. Group analogy; 4. Hidden semantic 5. The number syllables; 6. Mo...

This is the first in a series of papers describing the Optical Redshift Survey (ORS), a redshift survey of optically selected galaxies covering 98% of the sky above |b| = 20 (8.09 ster). The survey is drawn from the Uppsala Galaxy Catalogue (UGC), the European Southern Observatory Galaxy Catalogue (ESO), and the Extension to the Southern Galaxy Catalogue (ESGC), and contains two sub-catalogs, o...

Previous studies of chemical carcinogenesis in the lung of Syrian golden hamsters have utilized outbred (nonsyngeneic) animals. Using the endobronchial sustained release implant technique, which causes focally orig inating cancers in outbred hamsters, we studied the course of bronchial carcinogenesis in two varieties of syngeneic Syrian golden hamsters, the I SI I and the 1,1) strains (BIO 15.1...

Cell-mediated immunity to fibroblasts transformed by herpes simplex virus type 2 was investigated with a lymphocyte assay system. The assay system was first standardized with phytohemagglutinin, a nonspecific stimulator of blastogenesis. Ham ster splenic and blood lymphocytes reacted to phytohemagglutinin with a dose-response curve similar to that reported for other rodent species. Splenic lymp...

After a sequence of improvements Boyd, Sitters, van der Ster, and Stougie proved that any 2-connected graph whose n vertices have degree 3, i.e., a cubic 2-connected graph, has a Hamiltonian tour of length at most (4/3)n, establishing in particular that the integrality gap of the subtour LP is at most 4/3 for cubic 2-connected graphs and matching the conjectured value of the famous 4/3 conjectu...
