A device for controlling fluid flow. The device includes an arc generator coupled to electrodes. The electrodes are placed adjacent a fluid flowpath such that upon being energized by the arc generator, an arc filament plasma adjacent the electrodes is formed. In turn, this plasma forms a localized high temperature, high pressure perturbation in the adjacent fluid flowpath. The perturbations can be arranged to produce vortices, such as streamwise vortices, in the flowing fluid to control mixing and noise in such flows. The electrodes can further be arranged within a conduit configured to contain the flowing fluid such that when energized in a particular frequency and sequence, can excite flow instabilities in the flowing fluid. The placement of the electrodes is such that they are unobtrusive relative to the fluid flowpath being controlled.

A Lamb-wave high-frequency resonator includes a comb-shaped IDT electrode for exciting a Lamb wave on one main surface of a quartz substrate. The IDT electrode is formed such that the cut angle of the quartz substrate and the direction of propagation of the Lamb wave are expressed in Euler angles (0, θ, 0).

For example, the present disclosure provides exemplary embodiments of a coil arrangement that can include, e.g., a plurality of elements which can be provided at an angle from one another. The angle can be selected to effectuate an imaging of a target region of interest at least one of a predetermined depth or range of depths, for example. In certain exemplary embodiments according to the present disclosure, the angle can be selected to effectuate an exemplary predetermined transmit efficiency for at least one of the elements. Additionally, the exemplary angle can be selected to effectuate a predetermined receive sensitivity for at least one of the elements. Further, according to certain exemplary embodiments of a coil arrangement in according to the present disclosure, the angle can be adjusted manually and / or automatically.

The invention discloses a composite multifunctional polyethylene flame retardant chitin wooden fiber plastic floor sheet material, which belongs to the technology field of plastic floor sheet material production by adding enhanced modifiers and tackifiers, etc. into plastic waste and wood chips. The invention mainly solves the technical problem of environmental pollution caused by plastic waste and wood chips in mankind household garbage, changes waste into valuables for recovery and utilization, and saves resources. The key point of the technical scheme is that the sheet material is prepared by adding chitin or chitosan viscose fiber, Chinese medical stone, tourmalinite, coral fossil nanometer powder, a permanent fire retardant SCJ-9689, a modifier, a cross-linking agent and a tackifier, etc. in the plastic waste and the wood chips for fusion and calendaring. The sheet material in the invention can release trace elements, radiate far-infrared light, and spontaneously generate negative ions that are beneficial to human body health , has the functions of antibiosis, sterilization, flame retardation and biodegradation, and is widely used for decoration of indoor floor, separator plates and ceilings.
