The role of attractive forces in viscous liquids

, 2011
We present evidence from computer simulation that the slowdown of relaxation of a standard Lennard-Jones glass-forming liquid and that of its reduction to a model with truncated pair potentials without attractive tails is quantitatively and qualitatively

Physical nature of the central singularity in spherical collapse

, 2001
We examine here the nature of the central singularity forming in the spherically symmetric collapse of a dust cloud and it is shown that this is always a strong curvature singularity where gravitational tidal forces diverge powerfully.

Investigation of frictional behaviour in incremental sheet forming of grade one titanium sheet [PDF]

MATEC Web of Conferences
Incremental Sheet Forming (ISF) is a flexible sheet forming process. Its interfacial friction between the ISF tool and the blank sheet has a significant effect to the forming forces, deformation, fracture, and surface finish.

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Manufacturing of irregular shapes through force control in incremental sheet forming with active medium

Advances in Industrial and Manufacturing Engineering
Convex shapes can be created in incremental sheet forming by supporting the workpiece with the pressure of an active medium. In this paper, a method is presented for creating irregular convex shapes by adjusting the pressure to control the forming forces.

Development of a new machine system for the forming of micro-sheet-products [PDF]

, 2008
Most of the developed micro-forming machines were based on standalone concepts which do not support efficient integration to make them fully automated and integrated.

Characterizing Parental Concerns About Lasting Impacts of Treatment in Children With B‐Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...

Understanding and predicting forming quality of copper in incremental sheet forming: forming forces, material properties, and geometric deviation

Journal of Materials Research and Technology
The influence mechanisms on forming quality in incremental sheet forming (ISF) remain inadequately elucidated, which significantly restricts the quality prediction accuracy and hinders widespread industrial application of ISF process.
