DYNAMIC MECHANICAL PROPERTIES OF OXYGEN FREE COPPER UNDER THE IMPACT LOAD

Jixie qiangdu, 2015
The dynamic mechanical properties of oxygen free copper has been tested under the different strain rate（ 2 500s- 1 15 500 s- 1） at the room temperature by split Hopkinson pressure bar（ SHPB）,the true stress-true strain curves has been obtained. Power-Law

The Role of Social Food Infrastructure in Addressing SNAP Participation Gaps: Evidence From Linked Administrative and Ground‐Sourced Data

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We link American Community Survey and SNAP records for 185,000 units with ground‐sourced social food infrastructure data from FindFoodIL (Illinois Extension SNAP‐Ed) to examine SNAP participation determinants among eligible units. Bivariate probit models reveal, beyond SNAP offices, quantity of social infrastructure is associated with ...

Pricing Dynamics in the US Hemp Market: A Vertical Price Transmission Analysis of the Hemp Value Chain

Agribusiness, EarlyView.
ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...

First Successful Regeneration of a Structurally Native‐Like Colon Using a Bioabsorbable Polymer Sheet

Annals of Gastroenterological Surgery, EarlyView.
This study demonstrated that a bioabsorbable polymer sheet (BAPS) can regenerate approximately half the circumference of the colon with native‐like structure and function in an experimental setting. As the model involved immediate closure after perforation and did not reproduce peritonitis, caution is required when considering clinical applicability ...
