Advanced Engineering Materials, EarlyView.Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

The autoparametric 3:2 resonance in conservative systems [PDF]
, 2005 In the resonance model, high-frequency quasi-periodic oscillations (QPOs) are supposed to be a consequence of nonlinear resonance between modes of oscillations occurring within the innermost parts of an accretion disk. Several models with a prescribed mode--mode interaction were proposed in order to explain the characteristic properties of the ...

A Novel Simulation Approach for Damage Evolution during Tailored Forming
Advanced Engineering Materials, EarlyView.Traditional damage models are struggling to accurately and efficiently simulate large‐scale three‐dimensional models with a great number of degrees of freedoms. A new gradient‐enhanced damage model based on the extended Hamilton principle can significantly reduce the computation time while ensuring mesh‐independence which is suitable to use in tailored

On the Baryonic Density and Susceptibilities in a Holographic Model of QCD [PDF]
Nucl.Phys.B822:201-218,2009, 2009 In this paper, we calculate analytically the baryonic density and susceptibilities, which are sensitive probes to the fermionic degrees of freedom, in a holographic model of QCD both in its hot QGP phase and in its cold dense phase. Interesting patterns due to strong coupling dynamics will be shown and valuable lessons for QCD will be discussed.

Kebebasan Pers Dilihat dari Perspektif Konflik, antara Kebebasan dan Tertib Sosial
Jurnal Ilmu Komunikasi, 2013 : Press in this country is joying optimal freedom since the falldown of Soeharto regime. But western-style freedom of the press is echoing numerous negative impacts. Prominent among those impacts are reports or news that considered defamation.

Advanced Engineering Materials, EarlyView.Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

Mode-coupling theory for structural and conformational dynamics of polymer melts [PDF]
, 2002 A mode-coupling theory for dense polymeric systems is developed which unifyingly incorporates the segmental cage effect relevant for structural slowing down and polymer chain conformational degrees of freedom. An ideal glass transition of polymer melts is predicted which becomes molecular-weight independent for large molecules.

Pacific Journalism Review, 1996 Malawi is an example of the utter extremes of press censorship. It never experienced press freedom until 1993. The Malawi people are still bitter after three decades of Banda's rule. The people's new experience in press freedom has given them their first
