Radiation Pressure Feedback in Galaxies [PDF]
We evaluate radiation pressure from starlight on dust as a feedback mechanism in star-forming galaxies by comparing the luminosity and flux of star-forming systems to the dust Eddington limit.

Densification behaviour of sintered aluminum composites during hot deformation
In this study, an investigation on the densification behavior and forming limit of powder metallurgy composites containing hard carbide particles were carried out. The selected composite materials are Al4TiC, Al4WC, Al4Fe3C and Al4Mo2C. The compacts of 0.

Experimental And Theoretical Determination Of Forming Limit Curve
The paper presents a method for determining forming limit curves based on a combination of experiments with finite element analysis. In the experiment a set of 6 samples with different geometries underwent plastic deformation in stretch forming till the ...

Search for anions in molecular sources: C4H- detection in L1527 [PDF]
We present the results of a search for the negative ion C4H- in various dark clouds, low mass star-forming regions and photon-dominated regions (PDRs). We have also searched for C6H-, C2H- and CN- in some of the sources.

High-Energy Limit of Form Factors [PDF]
This theorem is proved: For finite charge renormalization constant Z3-1, the form factors describing any vertex with two particles on the mass shell must vanish at infinite momentum transfer. The relation of this result to the work of Lehmann, Symanzik, and Zimmermann is discussed.

How Aspects of Self-Compassion Contribute to Wellbeing and the Effect of Age [PDF]
For modern high strength steels, instead of metal instability, ductile damage triggered by the formation of microvoids or microcracks resulting from the complex material microstructure, has become the key factor responsible for the final failure in the ...

Prediction and Verification of Forming Limit Diagrams Based on a Modified Shear Failure Criterion
The forming limit diagram plays an important role in predicting the forming limit of sheet metals. Previous studies have shown that, the method to construct the forming limit diagram based on instability theory of the original shear failure criterion is ...

A Search for H2O in the Strongly Lensed QSO MG 0751+2716 at z=3.2 [PDF]
We present a search for 183 GHz H_2O(3_13-2_20) emission in the infrared-luminous quasar MG 0751+2716 with the NRAO Very Large Array (VLA). At z=3.200+/-0.001, this water emission feature is redshifted to 43.6 GHz.
