The invention may be broadly defined as the addition of Argon to FFPE procedures as an RNA stabilizing agent. Argon is an inert gas from the Noble gas group with low saturation concentrations in water. It is therefore highly surprising that Argon would have any effect on RNA stability in the presence of Formalin, or any other chemical. This property of Argon appears to be specific in that other inert gases fail to show any RNA stabilizing effect.

Use of argon as a tissue fixation preservative

The present invention is a cryogenic subterranean fracturing fluid, comprising a liquefied industrial gas and a viscosity increasing additive. The liquefied industrial gas may be liquefied carbon dioxide, liquefied nitrogen, or a blend of the two. The liquefied industrial gas mixture should be substantially free of water. In this context, substantially free of water means less than 10% water by volume, or preferably less than 5% water by volume. In addition to the viscosity increasing additive, a proppant may be added to the fracturing fluid. In addition to the viscosity increasing additive and/or proppant additional additives may be added to the liquefied industrial gas as required.

Embodiments of the invention generally provide methods and systems that distribute an additive in solid carbon dioxide in an interior of food processing equipment. The additive may be injected into a flow of liquid carbon dioxide upstream of an expander at or adjacent to the interior. Injection of the additive into the interior may be alternated with directing a flow of expanded carbon dioxide into the interior. In some embodiments, the freezing point of the additive with or without a diluent composition and/or additive(s) is lower than a temperature of the liquid carbon dioxide.

A CO-containing modified atmosphere packaging (MAP) gas is generated from a processing gas including COand an optional inert gas by applying an electric field under conditions sufficient to generate non-thermal plasma. The fresh appearance of meat or seafood is maintained for a longer time by storing them in a container with the MAP gas.

Scaling is controlled in a cooling water system with CO2 based upon measurements of the cooling water's pH, alkalinity and Caconcentration.

Method to inhibit scale formation in cooling circuits using carbon dioxide

The present invention provides a process for preparing polysulfide. More particularly, the process of the present invention allows one to prepare the amount of polysulfide needed using clarified white liquor, and to be used when and where it is needed during the cooking process. The process comprises reacting alkaline digesting liquor after clarification with a catalytic amount of a transition metal oxide catalyst, most preferably manganese dioxide. The reaction is conducted at a temperature of 98&#xb0; C. or less, and is conducted for a short period of time, e.g., less than five minutes, with no oxygen gas or air being introduced with the catalyst and the main flow of clarified liquor.
