Factors Influencing Plant Propagation Efficiency Via Stem Cuttings
The work aimed to study all the possible factors affecting efficiency of plant propagation via stem cuttings. Several factors including type of cutting, culture medium, type and concentration of growth regulators were investigated. These factors were studied on Ficus hawaii as woody tree and Chrysanthemum morifolium as herbaceous plant to investigate the effect of plant type factor. All experim...
متن کاملScm-drill Cuttings Bioremediation
Traditional methods for the disposal of Oil-Based Mud (OBM) drill cuttings have included pit burial or leaving the untreated cuttings scattered in-situ. Increasingly stringent regulations and increased environmental awareness have required new and improved disposal techniques. Scomi Equipment Inc, with over twenty one years Drilling Waste Management experience, has developed a system to remedia...
متن کاملCuttings in 2D Revisited
Given n lines in the plane, a (1/r)-cutting is a subdivision of the plane into cells such that each cell intersects at most n/r lines. Cuttings are fundamental to the design of geometric divide-and-conquer algorithms and have numerous applications. Early suboptimal constructions of cuttings were given implicitly in the works by Megiddo and by Dyer in the 80s; simple randomized constructions wer...
متن کاملCuttings and applications
We prove a general lemma on the existence of {I/r)-cuttings of geometric objects in Ed that satisfy certain properties. We use this lemma to construct (I/r)-cuttings of (asymptotically) optimal size for arrangements of line segments in the plane and arrangements oftriangles in 3-space; for line segments in the plane we obtain a cutting of size O(r + Ar2/n2 ), and for triangles in 3-space our cu...
