This paper proposes a mechanism of controlling the diameter and separation of metallic nanorods from physical vapor deposition through self-organized seeds and experimentally demonstrates the feasibility using Ag as the prototype metal, In as the seed, and Si the substrate. Being non-wetting on Si substrates, deposited In atoms self-organize into islands. Subsequently deposited Ag atoms attach ...

Many staining protocols are widely applied in botanical microtechniques and serve specific histological purposes. In particular, some dyes used simultaneously to receive contrasting colorations of different chemical structures, e.g., lignin cellulose. One the most popular differential is based on Safranin O / Astra Blue combination. a water-soluble basic dye that stains red. also but having an ...

Mass spectrometry imaging (MSI) is a mass spectrometry based molecular ion imaging technique. It provides the means for ascertaining the spatial distribution of a large variety of analytes directly on tissue sample surfaces without any labeling or staining agents. These advantages make it an attractive molecular histology tool in medical, pharmaceutical, and biological research. Likewise, MSI h...

HISTOLOGY. Roy 0. Greep, Ed. New York, Blakiston, 1954. 953 pp., 648 figs., $15.00. This massive textbook of histology marks a new departure from the usual text. It began as a sixth edition of the text by Bremer and Weatherford and ended as a completely new book, both as to text and as to most of the illustrations. In addition, the chapters have been written by thirteen different contributors, ...

Dr. Strauss is aware of the importance to the body of the mechanisms influencing the disposal of water, although his teleology is sometimes tongue-in-cheek. In discussing diurnal variations in urine flow, "the teleologic usefulness of a diminished output of urine during the usual time of sleep requires no comment." Approximately twice as much space is devoted to thirst, water, and the antidiure...

The only hope is education, yet the limitations placed on this solution are severe. The author feels that the rightful function of education is to fit the young "to participate in their culture and to preserve it"; social change must come from the adult community, not the schools. In addition, each culture is "to have considerable respect for the past and its achievements, to rely on scrutiny a...
