The present disclosure provides approaches for reducing tobacco-specific nitrosamines (TSNAs) in tobacco. Some of these approaches include genetically engineering tobacco plants to increase one or more antioxidants, increase oxygen radicle absorbance capacity (ORAC), or reduce nitrite. Also provided are methods and compositions for producing modified tobacco plants and tobacco products therefrom comprising reduced TSNAs.

A mixer is less likely to cause lower operability due to vibration. A mixer includes a body including a motor and an output shaft to output rotation of the motor, a mixer shaft connectable to the output shaft, a handle attached to the body and including a grip, and a vibration isolator between the mixer shaft and the grip.

A device or system includes a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough. The mixer is in communication with sources or streams of at least two separate components which, when mixed, form a combined fluid stream. The sources or streams may be, at least initially, on opposite sides of the mixer, or the sources or streams may be on the upstream side of the mixer with an outlet disposed downstream of the mixer. A related method may include providing a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough, and selecting a material for the mixer based on physical characteristics of said material, said characteristics including a selected one or more of mean flow pore size, thickness and porosity volume.

There is provided an apparatus and a method for producing a play compound and the play compound itself which, in one embodiment is a compound which sufficiently fluid to be pliable and is typically cold and slimy to the touch. The apparatus and a method provide a powder and liquid to a user, which can be a non-skilled person and thereby allow the mixing of the powder and liquid together by that person to form the play compound outside of a factory environment whilst ensuring that the play compound which is formed has the desired characteristics. Most typically the user which performs the mixing can be the end user, such as a child, who will play with the compound and so the formation of the play compound forms a new part of the play experience.

A water bottle system for adding an additive, which may be flavoring, to the line of flow without contaminating the main reservoir. The system may include a water bottle with a lid feature that may maintain a flavor that may be infused into the water within the water bottle. The infusion of the additive may be adjusted by a user to have the desired concentration of additive to a user’s liking. The additive cartridge may be reusable or disposable depending on a user's preference.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head

A method and an adapter for improving the efficiency of a static mixer being used to mix reactive fluids such as epoxy adhesives. This allows either a small static mixer to be employed, or a smaller purge flow during dispensing operations.

The present disclosure provides approaches for reducing tobacco-specific nitrosamines (TSNAs) in tobacco. Some of these approaches include genetically engineering tobacco plants to increase one or more antioxidants, increase oxygen radicle absorbance capacity (ORAC), or reduce nitrite. Also provided are methods and compositions for producing modified tobacco plants and tobacco products therefrom comprising reduced TSNAs.

A portable drink blender includes a blade rotation axis offset from center such that the blender blades to not extend across in interior of the drinking spout. The motor housing is formed of a lower housing having the complete spout formed therein, and an upper housing including an aperture through which the spout extends. A cover interlock is provided which prevents operation of the motor unless the cover is in the closed position to seal the spout closed.

A reagent preparation assembly includes a body and a reaction chamber adjacent the body, the reaction chamber includes a reagent therein, such as a lyophilized reagent. An access port extends into the reaction chamber, and the access port is configured to receive an instrument. A seal extends across a portion of the reaction chamber and the access port. A reconstitution assembly is movably coupled with the body. The reconstitution assembly includes a plunger, a syringe and a piston. The plunger is movably coupled with the body. The syringe is selectively engaged with the plunger. The syringe includes a solution reservoir containing a solution, and movement of the syringe pierces the seal. The piston is selectively engaged with the plunger, and the piston is movably coupled within the syringe. Movement of the piston pushes the solution into the reaction chamber.
