Abstract: Characterizing the decay of the microstructure of a drilling fluid gel using a model based on two exponential functions. Based on the model, identify at least two components of the decay model comprising a fast decay component and a slow decay component, wherein the fast decay component decays more quickly than the slow decay component. The decay of the microstructure of the gel over a time period can be determined using a rheometer or viscometer. Wellbore processes, including start up and tripping operations can be optimized based on the determination of the fast decay component and/or a slow decay component of the drilling fluid gel.

Abstract: A device for measuring a tension of a bio-object construct as it is being stretched that includes a microscope, a holding member for accommodating the bio-object, and a probe. The microscope includes a condenser, an objective and a stage positioned therebetween. The stage is movable along a horizontal plane. The holding member is fixable on the stage. The probe has a first end attached to the condenser, and a second end placed in the holding member. The stage operably moves such that the bio-object construct moves toward the second end of the probe and contacts with the second end of the probe, thereby causing a displacement of the second end of the probe and a displacement of the bio-object construct, which are used to measure the tension of the bio-object construct.

Abstract: A PEFS (Piezoelectric Finger Sensor) acts as an “electronic finger” capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. The PEFS may be incorporated into a portable hand-held device. The PEFS offers superior sensitivity.
