Accuracy of standing-tree volume estimates based on McClure mirror caliper measurements

, : Accuracy of standing-tree volume estimates based on McClure mirror caliper measurements. USDA Forest Service Research Note, Southeastern Forest Experiment Station (SE-152): 4

Estimates of the total volume of 25 trees (three species of Pine and two of Oak, of various form and size) in an Oak/Pine stand in Florida, obtained from independent measurements by two workers with an optical caliper and sectional aluminium poles were within 2.1% of the values calculated from measurements on the felled trees.

A novel cDNA, designated human metalloendoprotease 1 (hMP1), was identified on the basis of homology to known metalloendoproteases of the pitrilysin family. The full-length MP1 codes for a protein with an open reading frame of 1038 amino acids. Th...

We have shown by northern analyses that the expression of the mouse polyubiquitin C gene is increased severalfold in the brains of mice infected with both the ME7 and 87V strains of scrapie. Expression of the polyubiquitin gene does not change sig...
