Chandra Observation of the Radio Source / X-ray Gas Interaction in the Cooling Flow Cluster Abell 2052 [PDF]

open access: yes, 2001
We present a Chandra observation of Abell 2052, a cooling flow cluster with a central cD that hosts the complex radio source 3C 317. The data reveal ``holes'' in the X-ray emission that are coincident with the radio lobes.

Experimental Study on Fibre-reinforced Cementitious Matrix Confined Concrete Columns under Axial Compression [PDF]

open access: yesKemija u Industriji, 2017
Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix ...

Straddle versus Conventional Chest Compressions in a Confined Space; a Comparative Study

open access: yesArchives of Academic Emergency Medicine, 2020
Introduction: When cardiac arrest occurs in a confined space, such as in an aircraft or ambulance, kneeling by the patient’s side may be difficult. Straddle chest compression is an alternative technique that can be used in a confined space. This study was

Deterministic spatio-temporal control of nano-optical fields in optical antennas and nano transmission lines [PDF]

open access: yes, 2008
We show that pulse shaping techniques can be applied to tailor the ultrafast temporal response of the strongly confined and enhanced optical near fields in the feed gap of resonant optical antennas (ROAs).

Internal Confining Stress of Internally Confined Hollow Columns under Compressive Load [PDF]

open access: yesJournal of Korean Society of Steel Construction, 2013
Internally Confined Hollow RC(ICH RC) column consisted of concrete, transverse reinforcement, longitudinal reinforcement, and inner tube. It had good strength and ductility by core concrete was become triaxial confining state with transverse reinforcement and inner tube.

Analytical modeling of reinforced concrete columns subjected to bidirectional shear [PDF]

open access: yes, 2017
Under general seismic loading, reinforced concrete columns may be subjected to lateral loads in more than one direction. Available experimental data on columns subjected to bidirectional forces indicate that higher levels of damage and a higher loss of ...

An investigation on the strain accumulation of the lightly EICP-cemented sands under cyclic traffic loads

open access: yesJournal of Road Engineering, 2023
Industrial production of chemical cement leads to extreme emissions of greenhouse gases. Biological or bio-inspired sustainable materials for soil treatment projects can be employed instead of chemical cement to heal the carbon cycle in the ecosystem ...

Local pressure-induced metallization of a semiconducting carbon nanotube in a crossed junction

open access: yes, 2005
The electronic and vibrational density of states of a semiconducting carbon nanotube in a crossed junction was investigated by elastic and inelastic scanning tunneling spectroscopy.

Clinical and magnetic resonance imaging characteristics of thoracolumbar intervertenral disk extrusions and protrusions in large breed dogs [PDF]

open access: yes, 2002
It has recently been shown that the fat-derived hormone adiponectin has the ability to decrease hyperglycemia and to reverse insulin resistance. However, bacterially produced full-length adiponectin is functionally inactive. Here, we show that endogenous

Fracture mechanics solution of confined water progressive intrusion height of mining fracture floor

open access: yesInternational Journal of Mining Science and Technology, 2015
In order to obtain the value of confined water progressive intrusion height of mining fracture floor, the analysis equation was deduced based on the fracture extension theory of the fracture mechanics. Furthermore, the influence of some parameters (e.g.,
