    Abstract: A wiresaw cutting fluid composition of the present invention comprises about 25 to about 75% by weight of a particulate abrasive suspended in an aqueous carrier containing a polymeric viscosity modifier that comprises a polymer including a majority of non-ionic monomer units (preferably 100 mol % non-ionic monomer units), has a number average molecular weight (Mn) of at least about 5 kDa, and is present in the composition at a concentration sufficient to provide a Brookfield viscosity for the composition in the range of about 50 to about 1000 cP, e.g., 50 to about 700 cP, at about 25° C. at a spindle rotation rate of about 60 rpm. In one embodiment, the viscosity modifier comprises a polymer having a weight average molecular weight (Mw) of at least about 200 kDa. When a viscosity modifier of 200 kDa or greater Mw is utilized, a preferred wiresaw cutting method the cutting fluid is circulated and applied by pumps and nozzles operating at a relatively low shear rate of not more than about 104 s−1.

    Abstract: An exemplary embodiment is directed to an equipment lubricating composition comprising useful microorganisms. An exemplary embodiment comprises a water insoluble, water-absorbent substance and an encapsulated microorganism component including viable microorganisms. This encapsulating material may encapsulate and protect the microorganisms by essentially preventing the microorganisms from contacting the external environment. Based on the protection afforded by the encapsulation, exemplary embodiments may include previously inhospitable carrier compounds such as particulate machine lubricants.
