River Research and Applications, EarlyView.ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

GEOmedia, 2019 At the half of July 2017, a big wildfire destroys a large area of Vesuvio and Mount Somma in the Vesuvio National Park. In this work, we have used Landsat8 multispectral set of images to study the area before and after the fire. We have used tiles of 05-

On the apparent absence of broad iron lines in Seyfert galaxies
, 2011 We present an analysis of XMM-Newton observations of eleven Seyfert galaxies that appear to be missing a broad iron K alpha line. These objects represent a challenge to the established paradigm for active galactic nuclei, where a relatively cold ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, EarlyView.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections
Structural Concrete, EarlyView.Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Correlation Study between H2 Permeation and Physical·Mechanical Property in Sulfur-crosslinked Nitrile Butadiene Rubber Polymer Composites Blended with Carbon Black and Silica Fillers [PDF]
한국정밀공학회지A study investigated hydrogen permeability in sulfur-cured NBR composites filled with carbon black (CB) and silica, using volumetric analysis across pressures ranging from 1.2 to 92.6 MPa. Both pure NBR and MT CB- and silica-filled NBR exhibited a single

Influence of External Fields and Environment on the Dynamics of Phase Qubit-Resonator System
, 2011 We analyze the dynamics of a qubit-resonator system coupled with a thermal bath and external electromagnetic fields. Using the evolution equations for the set of Heisenberg operators, that describe the whole system, we derive an expression for the ...

Exotic order in simple models of bosonic systems [PDF]
, 2002 We show that simple Bose Hubbard models with unfrustrated hopping and short range two-body repulsive interactions can support stable fractionalized phases in two and higher dimensions, and in zero magnetic field.

Structural Concrete, EarlyView.Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found
