Numerical Study and Theoretical Model of Shaped Charge Jet Penetrating Into Thick-Walled Target With Following Velocity by Jun-run Li, Yong-gang Lu, Bin Liang, Hengwei Xu, Xing Chen, Jian Zhang

“…Additionally, the lateral displacement is linearly correlated with stand-off distance. For normal penetration, the jet penetration depth decreases exponentially as the following velocity increases at the same stand-off distance. …”

Thinning Southern Pines - A Key to Greater Returns by Chris Demers, Michael Andreu, Babe McGowan, Alan Long, Jarek Nowak

“…Biologically, thinning accelerates stand development by favoring the tallest, best-formed trees over those that are diseased, overtopped, crooked, forked, or otherwise undesirable and likely to die on their own if left in the stand long enough. …”

Effects of Landform on Site Index for Two Mesophytic Tree Species in the Appalachian Mountains of North Carolina, USA by W. Henry McNab

“…Results from this study suggest that landform accounts for variation in site index of mesophytic species in mountainous terrain that is not explained by conventional stand variables associated with soil and topography.…”

Sesame (Sesamum indicum L.) Growth and Yield as Influenced by Preemergence Herbicides by W. J. Grichar, P. A. Dotray, D. R. Langham

“…No reduction in sesame stand was noted with any herbicide at south Texas location; however, at the High Plains location, linuron at the 2X rate reduced stand counts 28 days after treatment (DAT) in 2007 and diuron reduced sesame stand 147 DAT in 2008 when compared with the untreated check. …”

Timber Inventory: a primer for landowners by John Dooner, Michael G Andreu

“… This 7-page fact sheet written by John Dooner and Michael Andreu and published by the UF/IFAS School of Forest Resources and Conservation outlines a process called timber cruising, surveying timber inventory to estimate the current volume and value of a timber stand. The authors explain the process of timber cruising from initial tree-level measurements to the final total stand-level estimates and various methods for conducting the cruise. …”
