Sixteen stands were harvested by either clearcut, shelterwood, group selection, or singletree selection methods. Three of the stands had uneven-aged structure. The other 13 were typical, matrJre, even-aged stands. Hmest intensity @roportion of basal area removed) ranged from 0.27 to 1 .@I. Hanrestcd sites were similar in slope, average diameter at breast height (DBH), and pre-harvest diamcte.r ...

In this paper, the dynamic behavior of square plates with various thicknesses and stiffening configurations subjected to underwater explosion (UNDEX) are evaluated through a relatively novel approach which is called Incremental Explosive Analysis (IEA). The IEA estimates the different limit-states and deterministic assessment of plats’ behavior, considering uncertainty of loading conditions and...

PURPOSE To use angioscopy to evaluate and compare the amount of residual thrombus and endoluminal wall damage in hemodialysis grafts after percutaneous thrombectomy procedures. MATERIALS AND METHODS Thirty-nine thrombectomy and angioscopy procedures were performed in 35 patients. Percutaneous thrombectomy methods included eight different mechanical thrombectomy devices and the "lyse and wait"...

A numerical study is presented of the residual strength of an aircraft fuselage in the presence of multiple site damage (MSD)/muItiple element damage. The analyses were carried out using a software package that was developed to facilitate automated analyses of full-scale fuselage panels with widespread fatigue damage, using a hierarchical approach and elastic-plastic finite element alternating ...

Wind damage is a major disturbance interacting with forest development processes as well in natural forests as in managed forest. Models have been proposed to assess the risk of wind damage either with probabilistic approaches taking into account landscape, stand and tree attributes or with more mechanistic approaches at the scale of the tree. Allowing a precise description of the relations bet...

[1] We introduce the preconditioned generalized minimum residual (GMRES) method, along with an outer loop (OL) iteration to solve the sea-ice momentum equation. The preconditioned GMRES method is the linear solver. GMRES together with the OL is used to solve the nonlinear momentum equation. The GMRES method has low storage requirements, and it is computationally efficient and parallelizable. It...

Composite sandwich materials have yet to be widely adopted in the construction of naval vessels despite their excellent strength-to-weight ratio and low radar return. One barrier to their wider use is our limited understanding of their performance when subjected to air blast. This paper focuses on this problem and specifically the strength remaining after damage caused during an explosion. Carb...

When a person standing upright raises an arm on cue, muscles of the left and right sides of the body exhibit changes prior to and specific to the responding arm. We had standing participants perform a visual lexical decision task ("is this letter string a word?"), responding yes by raising one arm and no by raising the other arm. We recorded onset of the arm movement and onset of electromyograp...

Question: Can lichen communities be used to assess shortand long-term factors affecting seral quaking aspen (Populus tremuloides) communities at the landscape scale? Location: Bear River Range, within the Rocky Mountains, in northern Utah and southern Idaho, USA. Method: Forty-seven randomly selected mid-elevation aspen stands were sampled for lichens and stand conditions. Plots were characteri...
