the density functional theory (dft) and the natural bond orbital (nbo) calculations basedmethod b3lyp/6-31g* were carried out to study the interaction of carbon nanotube (8,0) withnitrobenzene in two situations perpendicular and parallel. formation energies of compounds,charges, the highest occupied molecular orbital (homo) and the lowest unoccupied molecular'orbital (lumo) and the homo-lumo ba...

With increasing computational resources, environmental models are run at finer grid spacing to resolve the land surface characteristics. The land use/land cover (LULC) data sets input into land surface models are used to assign various default parameters from a look-up tables. The objective of this study is to assess the potential uncertainty in the LULC data and to present a reclassification m...

Two types of gap phenomena (types I and II ) have been described in human hearts and their electrophysiologic bases have been delineated. In both types of gap phenomena relatively early premature atrial impulses are blocked within some portion of the His-Purkinje system (HPS). By increasing the prematurity of the atrial depolarization, conduction to the ventricles resumes due to delay of the pr...

DECOMPOSITION THEOREM AND APPLICATIONS RAMI GROSSBERG AND OLIVIER LESSMANN Abstract. In this paper, we prove a decomposition theorem for abstract elementary classes K with the amalgamation property, under the assumption that certain axioms regarding independence, existence of some prime models, and regular types are satisfied. This context encompasses the following: (1) K is the class of models...

Gap junctions are present between nonpigmented and pigmented epithelial cells layers, as well as between the adjacent pigmented cells, but not between the nonpigmented epithelial cells which face the posterior chamber. The unusual feature of these gap junctions is a dark banding which regularly appears every three rows of subunits. This dark band is the equivalent width of two rows of facets.

Distance learning is more and more interesting to everyone. Learning Management Systems are capable to be the source of data for business intelligence software. Business Intelligence software integrated with Learning Management System can help to analyze the way student uses distance learning, what are the effects and how to improve its quality. This paper describes the design of Business Intel...

nvironmental degradation can inflict serious damage on poor people, because their livelihoods often depend on natural resource use, and their living conditions may offer little protection from pollution of the air, water and soil. At the same time, poverty-constrained options may induce the poor to deplete resources and degrade the environment at rates that are incompatible with long-term susta...
