High-density aluminum foam can provide higher stiffness and absorb more energy during the impact Obtaining constitutive law of such requires tri-axial tests with very high pressure, where difficulty may arise because hydrostatic pressure reach than 30 MPa. In this paper, instead using tests, we proposed three easier tests—tension, compression shear to obtain parameters model (the Deshpande–Flec...

ABSTRACT In a galaxy merger, the stars tidally stripped from satellite and accreted onto host undergo phase-mixing form finely grained structures in phase space. However, these fragile may be destroyed subsequent evolution, particular, by rotating bar that appears well after merger is completed. this work, we investigate survivability of phase-space presence bar. We find with amplitude pattern ...

In this study, polymer composite membranes comprising carbon nanotube (CNT), polysulfone (PSF) and polyvinyl alcohol (PVA) were synthesized via the phase inversion method and used to remove phenol from the phenol-containing wastewater. The fabricated membranes were reinforced with the functionalized carbon nanotubes (fCNTs) and coated with PVA to enhance their mechanical strength and anti-fouli...

We present the results of the Infrared Space Observatory Short Wavelength Spectrometer (ISO-SWS) observations of Jupiter related to ammonia. We focus on two spectral regions; the first one (the 10-μm region), ranging from 9.5 to 11.5 μm, probes atmospheric levels between 1 and 0.2 bar, while the second one (the 5-μm window), ranging from 4.8 to 5.5 μm, sounds the atmosphere between 8 and 2 bars...

Tension stiffening is an essential effect that influences the behaviour of concrete structures under serviceability conditions, mainly regarding crack control and deflection behaviour. Serviceability conditions can be studied experimentally by running so-called uniaxial tensile test. This paper reports extensive experimental research conducted to study reinforced Ultra-High Performance Fibre-Re...

We report on the 2: 00 5 (400 pc) resolution CO (J = 1 ! 0) observations covering the whole length of the bar in the strongly barred late-type spiral galaxy NGC 7479. CO emission is detected only along a dust lane that traverses the whole length of the bar, including the nucleus. The emission is strongest in the nucleus. The distribution of emission is clumpy along the bar outside the nucleus, ...

Weightlifting training and competition involves lifting a revolving shaft bar loaded with weights. The design of a bar and the location of the weights result in bar deformation during lifting tasks. Because there are many manufacturers of weightlifting bars, the actual deformation of a bar may vary, depending on the steel alloys used. A modified 4-point static bending test was used to assess de...

Directed neuroblast and neuronal migration is important in the proper development of nervous systems. In C. elegans the bilateral Q neuroblasts QR (on the right) and QL (on the left) undergo an identical pattern of cell division and differentiation but migrate in opposite directions (QR and descendants anteriorly and QL and descendants posteriorly). EGL-20/Wnt, via canonical Wnt signaling, driv...
