High core recovery at Ocean Drilling Program (ODP) Leg 210, Site 1276, provided a high-resolution porosity-depth relationship and an equally impressive age-depth model based on first and last occurrences of microfossils. Site 1276 was drilled over transitional crust in the Newfoundland nonvolcanic margin, offshore Canada, between known continental crust on the west and apparent oceanic crust on...

The spectral closeness of a graph G is defined as the radius matrix , whose ( u v )-entry for vertex and 2 − d u,v ) if ≠ 0 otherwise, where distance between in . residual nontrivial minimum subgraphs with one deleted. We propose local grafting operations that decrease or increase determine those graphs uniquely minimize and/or maximize some families graphs. also discuss extremal properties clo...

Research subject . Trap sills of the Daldin-Alakit diamond-bearing region western Yakutia. Aim To establish reason for influence sedimentary rocks containing kimberlite diatremes on introduction basite magma that forms trap and possibility using morphology as a search signs kimberlites. Materials methods Sections near kimberlites, their structure, petrographic petrochemical composition dolerite...

The late Miocene sandstone intrusions of northern Santa Cruz County, California, are the largest subaerial exposures of clastic intrusions on earth. The intrusions are sourced from a sandstone, underlying mudstone, accumulated in an outer shelf to upper slope environment. Dikes are the most frequent intrusion type, reach the greatest thickness and tend to strike north-east and dip steeply. One ...

Real technological, social and biological networks evolve over time. Predicting their future topology has applications to epidemiology, targetedmarketing, network reliability and routing in ad hoc and peer-to-peer networks. The key problem for such applications is usually to identify thenodes thatwill be inmore important positions in the future. Previous researchers had used ad hoc prediction f...

Scour downstream (DS) of hydraulic structures (HS) may endanger the safety of the structures if the necessary precuations are not considered during the design stage. Normally, different measures produce different effects on reducing the maximum scour depth DS of HS. One of the important HSs is the abruptly enlarged (or sudden expanding) stilling basins. In this paper, the effects of different a...

Forced hydraulic jump in a horizontal stilling basin with one and two continuous sills at the downstream end of an ogee standard weir was investigated. Experiments were completed on sills of five different heights which were fixed at two different distances from the toe of the weir. The main characteristics of the jump such as the sequent depth ratio, relative roller length, and relative ener...

Magma emplacement is commonly accommodated by uplift of the overburden and free surface. By assuming this deformation purely elastic, we can invert shape kinematics ground to model geometry dynamics underlying intrusions. However, magma be viscoelastic and/or inelastic processes. We use 3D seismic reflection data reconstruct how elastic bending processes a Late Jurassic sill offshore NW Austral...
