the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...

Three-dimensional (3D) backside reflector, compared with flat reflectors, can improve the probability of finding the escape cone for reflecting lights and thus enhance the light-extraction efficiency (LEE) for GaN-based light-emitting diode (LED) chips. A triangle-lattice of microscale SiO2 cone array followed by a 16-pair Ti3O5/SiO2 distributed Bragg reflector (16-DBR) was proposed to be attac...

in this paper, we prove the existence of fixed point for chatterjea type mappings under $c$-distance in cone metric spaces endowed with a graph. the main results extend, generalized and unified some fixed point theorems on $c$-distance in metric and cone metric spaces.

During development, neurons must find their way to and make connections with their appropriate targets. Growth cones are dynamic, motile structures that are integral to the establishment of appropriate connectivity during this wiring process. As growth cones migrate through their environment, they encounter guidance cues that direct their migration to their appropriate synaptic targets. The gas...

Recently, Cho et al. [Y. J. Cho, R. Saadati, S. H. Wang, Common xed point theorems on generalized distance in ordered cone metric spaces, Comput. Math. Appl. 61 (2011) 1254-1260] dened the concept of the c-distance in a cone metric space and proved some xed point theorems on c-distance. In this paper, we prove some new xed point and common xed point theorems by using the distance in ordered con...

The pulsar profile is characterised by two distinct emission components, the core and cone. standard model of a radio beam originating from dipolar magnetic fields, places at centre surrounded concentric layers inner outer conal components. expected to have steeper spectra compared cones. We present detailed analysis relative differences in between large sample 53 pulsars over wide frequency ra...

The monotone iterative technique, theory of fixed point index in a cone and the Leggett-Williams theorem are applied to investigate existence multiplicity positive solutions for four boundary value problems nonlinear fractional differential equations with p-Laplacian operator infinite delay. Moreover, examples presented illustrate vast applicability our main results.

ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...
