We compare estimates of peer effects on worker output in laboratory experiments and field studies from naturally occurring environments. The mean study-level estimate of a change in a worker's productivity in response to an increase in a co-worker's productivity (γ) is γ̑ = 0.12 (SE = 0.03, n(studies) = 34), with a between-study standard deviation τ = 0.16. The mean estimated γ̑-values are close ...

This study was conducted to determine the effect of spent instant coffee grounds (SICG) on odor emission characteristics as bedding material in sawdust bedded pack barn Hanwoo farm. Two experiments were performed five treatments (0, 25, 50, 75, and 100% SICG, a lab scale) four 75% field trial). Chemical composition, moisture absorption ability, water holding capacity, intensity, dilution draina...

This study evaluated the CO2 sequestration potential with combustion ashes in aqueous phase. The aim was to provide a cost-effective carbon method for unit operators (flue gas cleaning) or biogas producers (biogas upgrading). Therefore, two separate test series were executed identify carbonation efficiency (CE) of bottom wood ash (1) at different mixing ratios water batch experiments and (2) un...
