Reproducibility of a Laboratory Based 20-km Time Trial Evaluation in Competitive Cyclists Using the Velotron Pro Ergometer
Autor: B. C. Sporer, D. C. McKenzie
Publikováno v: International Journal of Sports Medicine. 28:940-944
The purpose of this study was to evaluate the reliability of a 20-km cycling time trial using the Velotron cycle ergometer in competitive cyclists. Twenty male cyclists (V.O (2max) = 68.5 +/- 3.6 ml . kg (-1) . min (-1); peak power (P (peak)) = 469 +

Soil compaction: identification directly in the field
Autor: T. Batey, D. C. McKenzie
Publikováno v: Soil Use and Management. 22:123-131
The compaction of soil alters its structure, increases its bulk density and decreases its porosity. These changes can be detected by careful and systematic visual and tactile examination directly in the field. These changes also reduce the permeabili

Physicians' Exercise Habits: Most believe in exercise but don't do enough
Autor: L M, Stevenson, D C, McKenzie
Publikováno v: Canadian family physician Medecin de famille canadien. 38
We distributed a questionnaire on personal exercise profiles, attitudes toward exercise, and counseling behavior to a random sample of 200 Vancouver general practitioners. Of the respondents, 39.1% met American College of Sports Medicine guidelines.

The effect of tillage and gypsum application on the macropore structure of an Australian Vertisol used for irrigated cotton
Autor: Alex B. McBratney, A.J. Koppi, M.R. Wild, D. C. McKenzie
Publikováno v: Soil and Tillage Research. 22:55-71
Structural degradation of Vertisols (cracking grey clay soil) as a result of growing cotton under furrow irrigation has resulted in declining cotton yields. This degradation may be ameliorated with suitable management. A field experiment at Warren, N

The use of air-filled porosity and intrinsic permeability to air to characterize structure of macropore space and saturated hydraulic conductivity of clay soils
Autor: P. S. Blackwell, Anthony Ringrose-Voase, K. A. Olsson, D. C. Mckenzie, W. K. Mason, N. S. Jayawardane
Publikováno v: Journal of Soil Science. 41:215-228
SUMMARY Intrinsic permeability to air of macropore space (ka) is related to macroporosity (ɛ) and organization of macropore space (O). Organization is defined as ka/ɛ. The use of ka for estimating saturated hydraulic conductivity (Ka) is also consi
