Mensuration of the Dried Collodion Membrane (calcu- Lation of Dimensions and of Relations

In a previous paper of this series a flat form of the dried collodion membrane and its method of preparation was described (1). As this form of membrane presented certain advantages in durability and convenience of manipulation over the previously used bag membranes, it was the type used in most of the subsequent investigations. Electric transfer experiments in which relatively strong electric ...

Mensuration of spermatozoa from different levels of the reproductive tract of the buffalo - bull ( Bubalus bubalis )

The dimensions of spermatozoa from different levels of the reproductive tract were measured in 6 buffalo-bulls castrated under local anesthesia ; the same measurements were taken in the semen of 6 breeding buffalo-bulls.

Use of Ancillary Data to Improve the Analysis of Forest Health Indicators

In addition to its standard suite of mensuration variables, the Forest Inventory and Analysis (FIA) program of the U.S. Forest Service also collects data on forest health variables formerly measured by the Forest Health Monitoring program. FIA obtains forest health information on a subset of the base sample plots. Due to the sample size differences, the two sets of variables have traditionally ...
