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 Regeneration Dynamics Successful regeneration of oak on intermediate and high-quality sites (upland oak site index > 65 to 70 feet) is limited due to the lack of the vigorous advance regeneration and/or saplings/pole-sized trees that are capable of sprouting. Vigorous advance regeneration and/or stump sprouters are required at the time of regeneration on intermediate and highquality sites, ...

Methods Twenty nine consecutive patients with local recurrence after definitive SCC operation from April 2006 to September 2012 were included. Preand post-operative CT from these patients were retrospectively reviewed and compared with those in ageand gender-matched 29 patients with stump deformity or granulation tissue at stump site after the definitive SCC operation, by two chest radiologists.

2 Director, Prosthetics Research Study, Seattle, Wash. AHE elective amputation must be considered plastic and reconstructive in nature. The need to create a dynamic and sensory motor end-organ should be foremost in the surgeon's mind in planning an amputation, and is emphasized here once more. The below-knee stump no longer hangs suspended in an open-end socket. The variable degrees of pressure...
