Studies on the physical and mechanical properties of some weed seeds


, : Studies on the physical and mechanical properties of some weed seeds. Gradinarska i Lozarska Nauka 9(4): 43-52

Size, weight, shape and colour were studied in many weed seeds so as to distinguish them from vegetable seeds during cleaning and grading.

This study examines the interactions between anteroposterior postural responses and the control of walking in human subjects. In the experimental paradigm, subjects walked upon a treadmill, gripping a rigid handle with one hand. Postural responses...

Hypersensitivity reactions in patients receiving metal-on-metal hip replacements have been attributed to corrosion products as observed by elevated cobalt and chromium ions in the blood. Although the majority of cases are reported in metal-on-meta...
