Application of polyelectrolyte complex nanoparticles to increase the lifetime of poly vinyl sulfonate scale inhibitor

EPSCoR Research Infrastructure Improvement Program AND Program Evaluation

Berkland C, Johnson S, Peltier K, Veisi M.
GSID: _X8i_VADjH0J
M Veisi, S Johnson, K Peltier, C Berkland… - … and Exhibition on …, 2018 - onepetro.org

Abstract Poly (vinyl sulfonate)(PVS) is an effective scale inhibitor in preventing the formation of barium sulfate. However, the low adsorption of PVS onto the rock results in a short squeeze treatment lifetime in reservoir. The application of nano-sized polyelectrolyte...

Polyelectrolyte complex stabilized CO2 Foam systems for hydraulic fracturing application

EPSCoR Research Infrastructure Improvement Program AND Program Evaluation

Johnson S.
GSID: u5jWJ-zhfbIJ
R Anandan, S Johnson, R Barati - SPE Liquids-Rich Basins …, 2017 - onepetro.org

Hydraulic fracturing of oil and gas wells is a water intensive process. Limited availability, cost and increasing government regulations restraining the use and disposal of fresh water have led to the need for alternative fracturing fluids. Using CO 2...

Controlled release of poly (vinyl sulfonate) scale inhibitor to extend reservoir treatment lifetime

EPSCoR Research Infrastructure Improvement Program AND Program Evaluation

Johnson S, Shafer‐Peltier K, Veisi M.
GSID: K9VQu-qO-OsJ
M Veisi, S Johnson, K Shafer‐Peltier… - Journal of Applied …, 2019 - Wiley Online Library

Precipitate scale formation is a major issue for the oil industry, plugging equipment, and reservoirs and resulting in increased operational costs. Poly (vinyl sulfonate)(PVS) is often used as a scale inhibitor to prevent the formation of barium sulfate scale....

The effect of three different toe props on plantar pressure and patient comfort.

Journal of foot and ankle research

Johnson S, Branthwaite H, Naemi R, Chockalingam N.
PMID: 22932230
J Foot Ankle Res. 2012 Aug 29;5(1):22. doi: 10.1186/1757-1146-5-22.

BACKGROUND: Arthritic toe pathologies frequently lead to the development of painful apical pressure skin lesions that can compromise gait and affect quality of life. Historically conservative treatments involve the use of a toe prop with the intended aim of...

Strips of Hope: Accuracy of Home Pregnancy Tests and New Developments.

Geburtshilfe und Frauenheilkunde

Gnoth C, Johnson S.
PMID: 25100881
Geburtshilfe Frauenheilkd. 2014 Jul;74(7):661-669. doi: 10.1055/s-0034-1368589.

The first home pregnancy test was introduced in 1976. Since then, pregnancy tests have become the most common diagnostic assay used at home. Pregnancy tests use antibodies to detect human chorionic gonadotropin (hCG). It is an ideal marker of...

Townson R, Tessier F, Galea R.
PMID: 29042149
Appl Radiat Isot. 2018 Apr;134:100-104. doi: 10.1016/j.apradiso.2017.10.010. Epub 2017 Oct 06.

The National Physical Laboratory Vinten 671 chamber was selected as a proving ground for a new radionuclide source model in the EGSnrc software. The computational Vinten model is validated against measurements of radionuclide artifacts whose activities were determined by...

Brain Activity in Self- and Value-Related Regions in Response to Online Antismoking Messages Predicts Behavior Change.

Journal of media psychology

Cooper N, Tompson S, O'Donnell MB, Falk EB.
PMID: 29057013
J Media Psychol. 2015;27:93-109. doi: 10.1027/1864-1105/a000146. Epub 2015 Sep 15.

In this study, we combined approaches from media psychology and neuroscience to ask whether brain activity in response to online antismoking messages can predict smoking behavior change. In particular, we examined activity in subregions of the medial prefrontal cortex...
