This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advances in NMR well logging — the MRF Magnetic Resonance Fluid Characterization Method and NMR “diffusion-editing” (DE) pulse sequences. We discuss the principle...

Wettability and NMR surface relaxation are related to each other. Wettability controls the fluid distribution in porous media. NMR surface relaxation dictates that the fluid in contact with the mineral surface has a relaxation time shorter than its bulk value. In this study, first, the nature of wettability effect on NMR responses was demonstrated by a parameter ρ2, eff, the effective surface r...

in order to simultaneously improve wet and dry strengths of paper and decrease environmental issues related to the wet strength resins, in this study effect of application method of wet strength additives on paper properties was investigated. wet strength resins were applied in four methods including spraying an aqueous glyoxal solution on to the surface of wet paper, addition of aminated polya...

With the development in egocentric vision, skill measurement has been recently proposed as a novel topic in this emerging field. In this report, we record the the experimenter’s first-person videos in Wet labratories (wetlab), and measure his/her operative skills. Specifically, given the videos of expert and amateur, we analyze their head motions, hands motions, eye-hand coordinations and key-m...

The objective of the study was to evaluate the detection efficiency of micro-vacuum surface sampling and surface wet wipe sampling in homes that had been identified with vermiculite attic insulation and/or other asbestos containing materials. Surface samples were collected pre and post weatherization activities and analyzed by transmission electron microscopy. Baseline sampling revealed that we...

We present a model for water uptake by plant roots from unsaturated soil. The model includes the simultaneous flow of water inside the root network and in the soil. It is constructed by considering first the water uptake by a single root, and then using the parameterized results thereby obtained to build a model for water uptake by the developing root network. We focus our model on annual plant...

Thank you for your comment that helped us to focus on some interesting issues. We fully agree with you that at subsaturated conditions (small droplets), the saturation (S) is dominated by the Raoult term (B/r3) and only as one approaches saturation (larger droplets) does the importance of the Kelvin term (A/r) increase. However, we disagree with the statement that ”At the critical supersaturati...
