In the majority of modern forest management systems, mature trees are harvested above the root collar, leaving stumps in the ground. Due to widespread concern about climatic change caused by anthropogenic emissions of greenhouse gases, increasing prices of fossil fuels and a desire to improve energy security, there is a growing interest in the exploitation of alternative sources of energy, incl...

OBJECTIVE The goal of this study is to characterize the phenomenon of evoked tactile sensation (ETS) on the stump skin of forearm amputees using transcutaneous electrical nerve stimulation (TENS). APPROACH We identified the projected finger map (PFM) of ETS on the stump skin in 11 forearm amputees, and compared perceptual attributes of the ETS in nine forearm amputees and eight able-bodied su...

A study was carried out on 93 consecutive unilateral below-knee (BK) and 62 above-knee (AK) amputees. The dimensions of the amputation stumps were measured and the general condition and contralateral limb assessed at the time of prosthetic fitting. After one postoperative year, follow-up information for 124 (89%) of the surviving patients was obtained by personal contact. The observations were ...

—Oak (Quercus spp.) stump sprouts are vital to sustaining oak’s presence and long-term dominance when regenerating oak or mixed-hardwood forests in southern Indiana. A study was initiated on the Hoosier National Forest in southern Indiana in 1987 to predict the sprouting potential and dominance probability of oaks. Before clearcut harvesting, we sampled 2,188 trees of fi ve oak species and meas...
