Fibula flap is widely used in reconstruction work, whereas the low extremity blood supply alteration was unclear. This study would observe the blood oxygen saturation change of foot after harvesting fibula flap. The regional tissue oxygen saturation (rSO2) of the lateral side and inner side of feet was measured using near-infrared spectroscopy oxygen monitoring system (NIRS) before operation an...

Due to large area disturbed and great deal of energy cost during-its operations, introducing or applying the appropriate timber extracting techniques could significantly reduce the impact of timber extraction operations to forest environment while pursuing the reasonable operation costs. Four environmentally sound timber extraction techniques for small tree harvesting, particularly for thinning...

Motivation In traditional energy harvesting applications, sensor nodes are able to store any excess energy in a storage device such as battery or supercapacitor for future use. If correctly dimensioned, such a system will guarantee the node’s operation during periods of energy unavailability. More recently, a radically different research line has emerged which focuses on batteryless, energy-dri...

This article aims to design a kind of gripping-belt speed automatic tracking system of traditional Chinese herbal harvester by AT89C52 single-chip micro computer as a core combined with fuzzy PID control algorithm. The system can adjust the gripping-belt speed in accordance with the variation of the machine’s operation, so there is a perfect matching between the machine operation speed and the ...

Cut-to-length (CTL) timber harvesting technology currently accounts for approximately 90% of Caspian forests. The technology involves felling, branching, cross-cutting, and then the skidder carries the logs to a landing, where the timber is temporarily stored, sorted and assembled for transportation to the mill. Cut-to-length systems typically require less labor, less access road construction, ...

The aim of the present experience was to evaluate the harvesting systems on the basis of trash content of raw material and the losses of millable cane, as a consequence of the harvesting operation. The analysed harvesting alternatives include differences in mechanical, semi-mechanical and manual systems and they have been evaluated in plots of 960 m2 of a same uniform sugar cane field, the test...

Grain harvest has to be done in a timely manner, in order to harvest the whole farm within the available suitable weather days for the operation. This short period combined with an increasing farm size, has lead farmers to buy more expensive combines with higher theoretical harvest capacity. A bigger combine does not automatically imply higher capacity. The grain harvesting process involves the...

The paper investigates the feasibility of using IEEE 802.11 in energy harvesting low-power sensing applications. The investigation is based on a prototype carbon dioxide sensor node that is powered by artificial indoors light. The wireless communication module of the sensor node is based on the RTX4100 module. RTX4100 incorporates a wireless protocol that duty-cycles the radio while being compa...
