Planet Migration through a Self-Gravitating Planetesimal Disk [PDF]

open access: yesarXiv, 2008
We simulate planet migration caused by interactions between planets and a planetesimal disk. We use an N-body integrator optimized for near-Keplerian motion that runs in parallel on a video graphics card, and that computes all pair-wise gravitational interactions. We find that the fraction of planetesimals found in mean motion resonances is reduced and

Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel

open access: yesAdvanced Engineering Materials, EarlyView.
The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.

Strategies to improve the implementation and effectiveness of community-based psychosocial support interventions for displaced, migrant and host community women in Latin America

open access: yesCambridge Prisms: Global Mental Health
As evidence supporting the effectiveness of mental health and psychosocial interventions grows, more research is needed to understand optimal strategies for improving their implementation in diverse contexts. We conducted a qualitative process evaluation

Period ratios in multi-planetary systems discovered by Kepler are consistent with planet migration [PDF]

open access: yes, 2012
The Kepler planet candidates are an interesting testbed for planet formation scenarios. We present results from N-body simulations of multi-planetary systems that resemble those observed by Kepler. We add both smooth (Type I/II) and stochastic migration forces. The observed period ratio distribution is inconsistent with either of those two scenarios on

Hybrid Framework Materials: Next‐Generation Engineering Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Hybrid organic–inorganic materials merge the unique properties of organic and inorganic compounds, enabling applications in optoelectronics, gas storage, and catalysis. This review explores metal‐organic frameworks, hybrid organic–inorganic perovskites, and the emerging field of hybrid glasses, emphasizing their structures, functionalities, and ...

Conceptual Problems in Forced Migration

open access: yesRefugee Survey Quarterly, 2013
Scholars have made rapid progress in establishing the field of Refugee Studies/Forced Migration Studies over the past 30 years. It has emerged from both the moral imperative of ameliorating the suffering of the displaced and from academic interests of scholars considering involuntary migration from the perspectives of sociology, geography, political ...

Fabrication of Compositionally Graded NiTi Shape Memory Alloy Laminated Composites Through Hot Roll Bonding and its Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Fractographic Analysis and Fatigue Behavior of Additively Manufactured Ni‐Superalloy Components with Post Processing Heat Treatment and Hot Isostatic Pressing

open access: yesAdvanced Engineering Materials, EarlyView.
A study of mechanical properties and fractography of PBF‐LB/M‐built Inconel 718, performing heat treatments and hot‐isostatic pressing, is presented. Ultimate tensile strength and fatigue behavior are evaluated, examining differences in maximum load behavior, elongation, and regimes of fatigue.

Recently resettled refugee women-at-risk in Australia evidence high levels of psychiatric symptoms: individual, trauma and post-migration factors predict outcomes

open access: yesBMC Medicine, 2018
Background Despite increasing numbers of refugee women-at-risk being resettled and their potential vulnerability, there exists no empirical research into the psychiatric health of this unique subgroup with which to guide policy and practice.
