Natural Height Control of Container Grown Eupatorium fistulosum

Oils extracted from Eupatorium adenophorum leaves show potential to control Phythium myriotylum in commercially-grown ginger

Oils extracted from the leaves of Eupatorium adenophorum were tested in vitro and in vivo against the soilborne pathogen Pythium myriotylum which causes soft rot, a devastating disease of commercial ginger production in China. Twelve compounds accounting for 99.15% of the total oil composition were identified by GC-MS. The major components were 10Hβ-9-oxo-agerophorone (37.03%), 10Hα-9-oxo-agero...

Treeshelter Use in Producing Container-grown Trees

Treeshelters were used for the nursery production of Cedrus deodara Loud. (deodar cedar), Quercus ilex L. (holly oak), and Magnolia grandiflora L. (southern magnolia) trees growing in 19-liter containers. Air temperature, relative humidity, and CO, concentration were higher inside the treeshelters than outside. Trees grown inside treeshelters were 74% to 174% taller than trees grown without she...

Myxobacteria exert partial control of damping-off and root disease in container-grown tree seedlings.

Seismic Effect of Height Fluid Filling on Storage Cylindrical Container

Liquid storage cylindrical containers are built for storing a variety of liquids. The seismic behavior of tanks is, however, quite complex problem. The interaction of tank and liquid can be simplified with the concept of generalized single-degree-of-freedom systems representing the convective, rigid impulsive and flexible impulsive vibration modes. This paper presents the theoretical background...

Hybrid control of container cranes

Hybrid cranes use ultracapacitors to store energy that is regenerated when lowering a container or during braking, and reuses this energy to assist the engine later on. A hybrid crane needs a system that optimizes the fuel cost by controlling in real time the two available power sources. Currently, the crane uses a rule-based heuristic strategy, which does not achieve optimal results and is dif...
