SummaryThe concentration of crude protein in grazed New Zealand pasture is typically in excess of 200 g/kg DM, which exceeds the requirement of the dairy cow and is reflected in elevated levels of daily urinary nitrogen (N) excretion, estimated to av

Some felid diets contain isoflavones but the metabolic capacity of cats towards isoflavones is relatively unknown, despite the understanding that isoflavones have divergent biological potential according to their metabolite end-products. The objectiv

Different approaches of dealing with mucosal injury during pyloromyotomy for hypertrophic pyloric stenosis have been described. There is, however, no consensus on the best technique to use. We conducted a survey among International Pediatric Endosurg

Selenium volatilization rates from plants and soil confined in a closed transparent chamber varied greatly among five plant species over 3− to 6-day collection periods. Astragalus bisulcatus and broccoli showed the highest rates of volatilization,

Light transmission through several sands, soils and size classes of glass beads was investigated. The glass beads served as a highly reflective model system for the sands. Light penetration was significantly better through sands than through either s

Mechanical reinforcement which stabilizes soil on slopes has been attributed to plant roots. To measure such reinforcement, direct shear tests were made on 25-cm diameter root-permeated soil columns. Roots of alfalfa (Medicago sativa), barley (Hordeu

A root-soil model developed previously has been extended to predict the amount of increase in soil shear resistance (root reinforcement) produced by stretching, slipping, and breaking roots of various sizes. We measured Young's moduli, tensile streng

Plant roots have been shown to increase soil shear resistance through direct mechanical reinforcement and thereby enhance soil stability on slopes. Because of their potential large diameter and length, the roots of trees may be especially significant

Plants enhance soil stability against downslope mass movement through the removal of soil water by transpiration and by the mechanical reinforcement of their roots. To assess the magnitude of this reinforcement, direct shear measurements were made on
