      Influence of steaming on various mechanical and physical properties of two European (Robinia pseudoacacia L., Quercus robur L.) and two tropical (Intsia bijuga, Hymenolobium petraeum) hardwood species were investigated. Each of these wood species requires adequate adhesive systems for the use as dimension stock because of their highly Cited by: a volume weighted average GEL for all species in the combination (D , Note 8).

    Hardwood log buckers significantly underachieve the potential value that could be produced from a stem is failure to recognize defects that reduce log grade and value. Poorly placed bucking cuts when manufacturing hardwood logs in the woods cause the resulting logs to be worth at least 25% less than could be realized. One important cause of value loss is failure by buckers to . Hardwood Species Availability 15 Summary 17 References Table.

utilization and forest management. Few data, however, exist on the weight, volume, and physical properties of the total tree and its components for hardwood species of this region.

To meet this need, a southwide study was initiated by the North Carolina State Hardwood Research Cooperative and the lJSDA Forest Service. Compatible segmented polynomial taper and volume functions were developed for yellow-poplar (Liriodendron tulipifera L.) from two ecoregions of West Virginia.

The data were based on stem analysis of 26 trees from the Central Appalachian Broadleaf Forest province in northern West Virginia and 18 trees from the Eastern Broadleaf Forest province in west central. Hardwoods.

The most common procedure is to use volume equations based on relationships between volume and variables such as diameter and height.

Stem taper functions are flexible and can provide estimates of diameter at any point along the stem, total stem volume, merchantable volume, and height to any specified top diameter.

For purposes of this chapter, three broad categories of taper equations were examined: simple functions, segmented functions, and variable-exponent by: 1. This study examined the occurrence of ellipticity on saw logs of four different Appalachian hardwood species employing measurements from a high-resolution laser scanning system.

This method allowed the determination of the greater and lesser axes measurements and the calculation of ellipticity at any point along the length of a log. PEER-REVIEWED ARTICLE Thomas et al.
