The carbon (C) cycle in boreal regions is strongly influenced by fire, which converts biomass and detrital C mainly to gaseous forms (CO2 and smaller proportions of CO and CH4), and some 1–3% of mass to pyrogenic C (PyC). PyC is mainly produced as

1. This study used 4 wheat cultivars (Brigadier, Chaucer, Consort, Reaper) from three locations (Crossnacreevy, C; Downpatrick, D; Limavady, L), which had given rise to differences in wheat specific weight (SW), to examine the relationships between a

1. A 3x3x2 factorial experiment studied the interactions of fat source (tallow, soya, tallow:soya [2:1] blend), wheat level (700, 350, 0 g/kg) and enzyme inclusion (Avizyme 1300, absent, present) in diets for broilers fed ad libitum in individual cag

1. The effect of diet form (mash, cold-pelleted, steam-conditioned/pelleted, wet mash, whole wheat with balancer pellet, restricted pellet) and enzyme inclusion (Avizyme 1300, absent, present) was studied in 2 trials using individually caged, male br

Herpes simplex virus type 1 (HSV-1) mutants defective in immediate-early (IE) gene expression do not readily enter productive replication after infection of tissue culture cells. Instead, their genomes are retained in a quiescent, nonreplicating stat

Optical emission spectroscopy provides a rapid and precise method for determining 15N/14N ratios of 15N‐enriched plant and/or soil samples. The objective of this study was to determine the effect of an indicator added in the distillation solution o

The thick folic (mainly upland forest) materials (> 40 cm of accumulated organic material) that occur in the Coastal Western Hemlock Biogeoclimatic Zone in British Columbia have not been described with regard to the spatial interrelationships of the

The assaying of nitrogen isotope abundance using emission spectroscopy commonly requires a plasma discharge in a sample of N2 gas at low pressure (∼0.5 kPa) in a sealed glass tube. Expensive high‐power (≳20 W) radio‐frequency or microwave amp
