Fertilization effects on interactions between above-and belowground competition in an old field
Download1999
Recent theoretical and experimental studies have addressed whether the relative importance of aboveground and belowground competition changes along gradients of biomass productivity. Results have been contradictory, with some researchers finding a decrease in the importance of belowground...

Good, Allen G., Beatty, Perrin H.
Globally, we are applying excessive nitrogen (N) fertilizers to our agricultural crops, which ultimately causes nitrogen pollution to our ecosphere. The atmosphere is polluted by N2O and NOx gases that directly and indirectly increase atmospheric warming and climate change. Nitrogen is also...

Steele, Michael A., Fisher, Rebecca E., Karrow, Niel A.
Adverse uterine environments experienced during fetal development can alter the projected growth pattern of various organs and systems of the body, leaving the offspring at an increased risk of metabolic disease. The thrifty phenotype hypothesis has been demonstrated as an alteration to the...

The physical properties of weft knitted fabrics can be modified according to the fabric structure and the raw material used to manufacture the final fabric. This research demonstrates the influence of fiber types and fabric structure on some specific physical properties such as bursting strength,...

Fiber-type proportions and diameters in the longissimus muscle of beef heifers undergoing catch-up (compensatory) growth
Download1991
Fifty-three Hereford crossbred heifers (211 ± 28(mean ± SD) kg, 197 ± 13 d of age at day 1) were used to study the effects of mild, chronic feed restriction followed by refeeding on some longissimus muscle fiber characteristics. Five animals were slaughtered on day 1 for analysis of initial...

Fibre-type characteristics and postmortem glycolysis of bison (Bison bison bison) longissimus lumborum
Download2002
Aalhus, J. L., Janz, J. A. M., Price, M. A.
To augment the limited information base, muscle fibre and postmortem glycolytic data from bison longissimus lumborum were compiled. As expected, postmortem glycogen concentration and pH declined while lactate concentration increased. Bison muscle fibres had a greater area, with a greater...

A comprehensive field program was implemented to evaluate the internal structure and hydrology of two full-scale waste rock piles. The excavation of waste rock dumps for in-pit disposal at the two mine sites provided an opportunity to characterise the in situ properties of the dumps given...

Sattler, Kelvin, Elwood, David, Hendry, Michael T., Berscheid, Brian, Marcotte, Bryce, Abdulrazagh, Parisa Haji, Huntley, David
Reliable, low-cost datalogging alternatives promote transfer of knowledge and technology to the wider geotechnical and geoscientist community. Alternative systems can ease increased data resolution on large projects, operate in remote locations with restricted site access, or allow developing...

Nordwick, S., Bless, D., Zaluski, M.
An innovative, biological treatment process has been designed by MSE Technology Applications, Inc to treat and control acid mine drainage (AMD). A field-scale demonstration is being conducted under the Mine Waste Technology Program using water flowing from a historic mine in Montana. A successful...

A practical field method for determining the maximum value of the intrinsic oxidation rate, Smax , of sulfidic materials in waste rock dumps is proposed. Knowledge of the intrinsic oxidation rate of sulfidic materials distributed in a dump is necessary for predictive modelling of oxidation and...
