A floating fish production system for placement within a body of water and being structured and disposed for containing fish and other aquatic animal, plant and algal species, the system including at least one primary containment tank having an arrangement of individual solid wall sections and an arrangement of individual solid floor sections. Flexible membranes span between and connect to adjacently positioned solid wall and floor sections to define flexible connecting joints that allow the individual solid wall and floor sections to move relative to one another in an articulating action. The flexible membranes allow the tank configuration to temporarily deform from a relaxed state in response to externally applied forces exerted on the tank (e.g., waves, wind, current) to thereby absorb the externally applied forces and reduce stress on the structural integrity on the tank. An air lift system including a high volume, low pressure blower and a spaced arrangement of vertically extending air lift pipes delivers water and oxygen from the exterior body of water and into the tank interior. A flexible main drain in a central area at the bottom of the tank connects to a waste recovery system for removing waste produced by the fish and other aquatic species.

A method of generating a model of propulsive efficiency for an autonomous underwater vehicle (AUV) is based on a multilayer perception neural network model using data from aquatic species, such as undulatory fin propulsion in the knifefish (Xenomystus nigri), and a sensitivity analysis is used to lower the number of required inputs. The model of propulsive efficiency allows an AUV to achieve high values of propulsive efficiency over a range of forward velocity, giving a lowered energy drain on the battery. In an embodiment, externally monitored information, such as that on flow velocity, is conveyed to an apparatus residing in the vehicle's control unit, which in turn signals the locomotive unit to adopt kinematics, such as fin frequency and amplitude, associated with optimal propulsion efficiency. Power savings could protract vehicle operational life and/or provide more power to other functions, such as communications.

Reducing agents or reducing agent precursors are provided for breaking ferric ion crosslinks in polymers in gelled acids used for diversion in matrix acidizing and used for leakoff control in acid fracturing.

Suitable compounds are sources of one or two hydrazines or sources of hydroxylamine. Such compounds are carbohydrazides, semicarbohydrazides, ketoximes, and aldoximes.

The present invention relates to a novel arrangement of denitrification reactors for removal of nitrate compounds in a recirculating aquaculture system. The novel arrangement of an aquaculture system of the present invention includes positioning one or more anaerobic denitrification reactors upstream of aerobic nitrification and degassing processes. One aspect of the present invention includes a flow of aqueous medium from aquatic species rearing tanks towards one or more denitrification reactors. Another aspect of the present invention includes flow of aqueous medium from aquatic species rearing tanks to a solids removing filter or mechanical filtration means for removal of solid waste matter or biomass prior to flow of aqueous medium towards one or more denitrification reactors. In a sequence of components comprising a system of the present invention, treated and denitrified aqueous medium exiting one or more denitrification reactors is directed towards a solids removing filter wherein treated and denitrified aqueous medium combines with untreated aqueous medium. Combined untreated aqueous medium and denitrified aqueous medium exits a solids removing filter and is directed towards an aerobic nitrification unit. Aqueous medium exiting the aerobic nitrification unit is degassed and oxygenated and returned to aquatic species rearing tanks. A system of the present invention which utilizes denitrification reactors positioned upstream of aerobic nitrification has advantages over existing aquaculture systems which use denitrification in reduction of nitrate concentrations. This results in greater mitigation of water chemistries and compounds which are harmful to aquatic species and more efficient use and conservation of water resources.

The vertical indoor ecosystem invention is an indoor vertical modular structure and method. The system includes at least one: retention tank, grow bed, grow tank, structural frame, recycling water supply, light energy supply and control units. Each grow tank supports both terrestrial and/or semi-aquatic plants and fresh water aquatic species.

The lowermost retention tank regulates water quantity and quality and typically houses larger aquatic species. Generally, the waste water from the retention tank travels up through a water pump to the top grow bed to filter water. Water travels down to the next lower level grow tank by gravity wherein plants uptake nutrients. Water returns to retention tank in a cyclical manner.

Provided are four new fluorescent proteins. The proteins were derived from two wild-type fluorescent proteins: a red fluorescent protein (RFP) that was isolated from Actinodiscus or Discosoma sp. 1 and a green fluorescent protein (GFP) isolated from Montastraea cavernosa. Two mutant forms were generated from each wild-type protein. Each of the mutated forms has a higher fluorescence intensity than the respective wild-type form. The mutant forms of the fluorescent proteins allow for more sensitive detection of the fluorescence emitted by the proteins. Additionally, one of the mutant proteins is more resistant to photobleaching than its wild-type protein. The invention also encompasses isolated nucleic acids encoding the mutant forms of the wild-type RFP and GFP.
