MAMBO 1.2mm observations of luminous starbursts at z~2 in the SWIRE fields [PDF]

, 2008
We report on--off pointed MAMBO observations at 1.2 mm of 61 Spitzer-selected star-forming galaxies from the SWIRE survey. The sources are selected on the basis of bright 24um fluxes (f_24um>0.4mJy) and of stellar dominated near-infrared spectral energy ...

The APEX-CHAMP+ view of the Orion Molecular Cloud 1 core - Constraining the excitation with submillimeter CO multi-line observations [PDF]

, 2011
A high density portion of the Orion Molecular Cloud 1 (OMC-1) contains the prominent, warm Kleinmann-Low (KL) nebula that is internally powered by an energetic event plus a farther region in which intermediate to high mass stars are forming.

Numerical investigation of temperature and forming rate effect on AA5086 warm formability

, 2010
International audienceThe poor formability of aluminum alloy at room temperature limits its use in some products with complex shapes, hence the warm forming process is intended to overcome this problem by using an elevated temperature.

High- and Low-Mass Star Forming Regions from Hierarchical Gravitational Fragmentation. High local Star Formation Rates with Low Global Efficiencies

, 2009
We investigate the properties of "star forming regions" in a previously published numerical simulation of molecular cloud formation out of compressive motions in the warm neutral atomic interstellar medium, neglecting magnetic fields and stellar feedback.

Simulation about Warm Forming Deep Hole in Sheet

International Journal of Control and Automation, 2016
The processing of forming deep hole in sheet is a kind of process using friction heat between drilling tool and workpiece to make workpiece in plastic deformation to machine hole. The process is a kind of green mechanical processing without chip. Studying green processing process in mechanical is becoming a development direction.
