Abstract: A compression spring with a sealed chamber formed by a resilient tube body, a top panel unit and a bottom panel unit. The chamber connects to an external elastic structure through a channel and a valve unit. The resilient tube body is a corrugated body defining a crest portion, a trough portion and the remaining portion. A rigid frame structure can be mounted on the crest and trough portions for facilitating expansion in the thinner remaining portion. When the chamber is fluid filled and pressed axially, the remaining portion deforms to hold a larger amount of fluid or the excessive fluid flows through the channel to the elastic structure. A rope unit can be provided for restricting axial expansion and preset a particular length range for a particular use. The valve unit can be controlled before or during the use of the compression spring to control the axial elasticity.

Abstract: Provided are methods and compositions to improve fungal disease resistance and/or nematode resistance in various crop plants. Also provided are combinations of compositions and methods to improve fungal disease resistance and/or nematode resistance in various crop plants. Powdery mildews are fungal diseases that affect a wide range of plants including cereals, grasses, vegetables, ornamentals, weeds, shrubs, fruit trees, broad-leaved shade and forest trees, that is caused by different species of fungi in the order Erysiphales.

Abstract: A spring unit includes a compressive spring, a reciprocating unit, and a connecting device provided on an upper end of the compressive spring. The reciprocating unit includes a base, a supporting frame movably supported on the base, and a pulling string. The pulling string has an upper end connected to the connecting device, and a lower end extended to connect to the base, and extends along a central space of the compressing spring and penetrating the supporting frame to connect between the connecting device and the base for normally exerting a predetermined downward force to the upper end of the compressive spring. The compressive spring is normally and slightly compressed by a pre-compression force exerted by the pulling string, so that when the compressive spring is subject to an external force, an extension of the compressive spring is non-linear and not directly proportional to the external force.
