摘要:
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit; injects an ozone-containing gas into the portion to provide an ozonated portion; recombines the ozonated portion with the flow of water in the conduit; and controls and regulates the diverted portion to provide a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.
摘要:
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit, injects ozone into the portion to provide an ozonated portion, and recombines the ozonated portion with the flow of water in the conduit. Another method and system identifies a species-destructive reaction product of ozone with a water constituent, determines a life of the reaction product, and contacts ozone with a water containing the species for a period determined according to the determined life of the reaction product.

A target biokill of species for water to be discharged from a ballast tank of a sea faring vessel is determined. A diverted portion of sea water is regulated prior to charging the water into the ballast tank. Regulation of the diverted portion of water and a rate of injection of the ozone into the portion are adjusted to attain the target biokill. Then ozone at the determined rate into the regulated diverted portion to attain the target biokill when the portion is recombined into the water for charging to the ballast tank.

摘要:
A surgical fixation system including a pair of spinal rods, an occipital fixation element (comprising either an occipital plate or a plurality of occipital anchors), a crosslink connector, and a plurality of anchor elements, including but not limited to friction-fit pedicle screws, favored-angle pedicle screws, and laminar hooks. Any or all of these elements may be made of a biologically inert material, preferably any metal customarily used for surgical devices, such as for example titanium or stainless steel. The surgical fixation system of the present invention is described herein for application to the posterior region of the human spine, for attachment to cervical and/or thoracic vertebrae, as well as the occiput portion of the skull.

An adjustable length corpectomy device is provided with a means for providing bidirectional length adjustment and a means for selectively fixing the length of the implant.
摘要:
An instrument guide and implant holding device is provided which releasably secures an implant to the instrument guide. The device provides a convenient guide for surgeons to perform various operative techniques on the subject bone without the need for separate devices, and allows all these operative techniques to be performed without removing the instrument guide from the dissected area until all operative techniques have been completed. The releasable mechanism allows the surgeon to easily hold the instrument to an implant using a simple press-fit approach, and easily releases from the implant with a minimal amount of force. An embodiment also allows the surgeon to releasably lock the cannula in a given orientation about the centroidal axis of the implant fastener hole.
