Mountain mahogany (Cercocarpus montanus Raf) is a useful reclamation species because it can occupy and improve poor soils. Literature regarding seed propagation of tbis species is var· ied and often contradictory, recommending stratification dura· tions of 14 to 90 days, and sulfuric acid scarification durations of none to 60 minutes. To assess variability in propagation require. ments among se...

I t used to be said that the Chicago nieat packers utilized everything but the pig's grunt. Many o f our latter,jay environmentalists seem to feel that the sanie degree o f tfficiency can be applied to recovery and reuse o f our nalion's mountaim of solid wastes. N o doubt. we can recover considerably greater amounts than we are presently nianaging. but this approach to the solution o f the sol...

Large-scale, distributed computer systems are less reliable than their smallscale, non-distributed counterparts. A significant proportion of the reliability problems are due to the very poor scalability of manual storage management techniques—the reclamation of unused storage in particular. The bulk of automatic garbage reclamation in both message-passing and shared memory systems, with certain...

In this chapter we focus on slack reclamation and propose a new slack reclamation technique, Multiple Frequency Selection DVFS (MFS-DVFS). The key idea is to execute each task with a linear combination of more than one frequency such that this combination results in using the lowest energy by covering the whole slack time of the task. We have tested our algorithm with both random and real-world...

This work is an assessment of perpetuated land degradation phenomenon and the attendant consequences in the oil producing areas of Nigeria. Certainly, following the oil production, is the emergence of squalors, generally run down environmental settings, erosion problems, general environmental degradation, pollutions among others. Thus, land reclamation efforts for effective uses constitute as a...

Taking Renjiazhuang coal mine as the object of study, this paper carries on evaluation to destruction degree in this area by using extension theory and establishing evaluation extension model of land destruction in mining area. Results show that severe destruction area of collapse land in Renjiazhuang coal mine is 112.86hm, moderate destruction area is 372.27hm, light destruction area is 723.42...

Aiming at developing a simple and efficient collision detection method to support the wandering in equipment deploy scene in land reclamation area of mining dump. This paper presents an efficient algorithm for collision detection in the waste dump land reclamation equipment deploy scene using a bounding volume nestification which consists of an oriented bounding boxes (OBBs) enhanced with axial...
