Coastal bermudagrass hay was labeled with Cr by the Cr-mordant procedure and with 177Lu applied to the same fiber. Neutral detergent fiber prepared from the same Coastal bermudagrass hay was labeled with Yb, 169Yb, Tb and 160Tb by soaking overnight following by thorough washing and drying. Wood chips were similarly labeled with Sm or La, and Solka Floc was labeled with 147Nd and 141Ce. The carr...

Air-stripping method was used to remove ammonia from the wastewater collected from natural gas fertilizer factory. Different materials were used as packing materials for the air stripping system. The effect of pH over 10.5, air-water flow ratio, nature of packing materials, height of materials and initial influent concentration of ammonia on air stripping unit were investigated. An attempt has ...

The objectives of this study were to determine the effect of using corn stover or three different wood-based bedding materials (kiln-dried pine wood chips, dry cedar chips, or green cedar chips) on airborne concentrations of NH, total reduced sulfides (TRS), CO, CH, and NO above lab-scaled bedded manure packs. Four bedded packs of each bedding material were maintained for two 42-d periods. Airb...

N-Methyl morpholine-N-oxide (NMMO) is an environmentally friendly and commercially applied cellulose solvent that is suggested for pretreatment of lignocelluloses to improve biofuel productions. However, the underlying mechanisms of the improvements have been poorly understood yet. In an attempt to investigate the mechanisms, pinewood powder and chips were pretreated with 85% (w/w) NMMO at 120°...

Pulp & Paper Canada T 230 105:10 (2004) ❘ ❘ ❘ 35 wood were interrupted at night or on weekends. Wood supplied to the chippers at this time of year was therefore largely fresh and the age of logs in inventory was generally low. Beginning in the fall, the inventory of cut wood was built up both in the mill’s wood yard and in roadside piles in the woodlands. In winter, this inventory of fall-cut w...

The pine wood nematode ~ B ~ 1 ~ c 1 ~ 1 e xyloplzil~~s) (PWN) has been intercepted in pine chips. unceasoned lumber and packing-case wood. Likehise. PWN insect vectors, Molzochnmus spp., have been found in pallets, crates, and dunnage. As a result of these interceptions and the known consequences of the introduction of the PWN. many countries regulate the import of coniferous wood. Science-bas...
