Mechanical Conditioning to Control Height
Mechanical conditioning is an excellent means of regulating the growth of vegetable transplants and some ornamental bedding plants. It improves the stature, appearance, handling characteristics, and overall quality of treated plants. The application procedures reported for transplants have included wind, shaking, brushing, and more recently impedance; all of which result in physical displacemen...
متن کاملUsing Impedance for Mechanical Conditioning of Tomato Transplants to Control Excessive Stem Elongation
Mechanical stimulation is known to control excessive stem elongation in high density tomato (Lycopersicon esculentum Mill.) transplants. Mechanical stimulation using physical impedance provided height control equivalent to that obtained using brushing. Low-cost materials can be used to apply the impedance. Mylar film in a plastic frame was equivalent to expensive acrylic sheets in its effect o...
متن کاملPad conditioning in chemical mechanical polishing: a conditioning density distribution model to predict pad surface shape
Abstract: Diamond disc pad conditioning is traditionally employed to restore pad planarity and surface roughness in chemical mechanical polishing (or planarisation) (CMP). In this paper, a conditioning density distribution model is developed to predict the pad surface shape resulted from the diamond disc conditioning in CMP. A kinematic study is carried out to calculate and simulate the diamond...
متن کاملControl, Conditioning, and Counseling
Psychology, as the science of behavior, is concerned with the understanding, prediction, and control of such behavior. Counseling and psychotherapy, it is asserted, have as goals the changing of behavior. An individual who is unproductive, unhappy, frustrated, dependent, irresponsible, overly submissive or overly aggressive, et cetera, is expected to become productive, happy, independent, respo...
متن کاملMechanical Conditioning for Control of Growth and Quality of Vegetable Transplants
Physical disturbance of plants or plant parts results in a mechanical stress response from the plant. Mechanical stress applied naturally or under controlled conditions inhibits growth in mass and dimensions of major plant parts. Wind and precipitation are important natural sources of mechanical stress. Under field conditions, cultivated plants experience these natural mechanical stresses plus ...
