Compression Debarking of Stored Wood Chips
, 1974 Two 750 ft. piles of unbarked chips were stored for 1 year to evaluate the effect of chip storage on the effectiveness of bark-chip separations-segregation methods under study.

Drying Rates of Wood Chips During Compression Drying [PDF]
, 2007 Compression drying is basically a process of forcing the free water in wood to move under high hydrostatic pressure through a solid structure. Fundamental information regarding the time-dependent characteristic of compression drying is necessary to ...

Defibration mechanisms of autohydrolyzed Eucalyptus wood chips
, 2013 The objective of this study was to evaluate the influence of autohydrolysis on mechanical defibration of Eucalyptus wood chips. The autohydrolysis process changed notably the mechanical properties of Eucalyptus chips. The removal of mainly hemicelluloses

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Transient and Dynamic First-Principle Modelling of Gasification Processes for Different Biomass Materials [PDF]
E3S Web of ConferencesThis study presents a transient and dynamic first-principle model of biomass gasification processes for wood chips and rice husk, implemented in GNU Octave. The syngas composition was analyzed over time, to show the level of variations in compositions of

Advanced Science, EarlyView.This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution
Advanced Science, EarlyView.Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...
