Surface complexation models (SCM), based mainly on the diffuse double layer (DDL) theory, have been used to predict zeta potential at the crude oil-brine-rock (COBR) interface with limited success. However, DDL is inherently limited in accurately predicting zeta potential...

The use of modified salinity and modified composition brines (MSMC), referred to as smart water, to alter carbonate surface wettability at different temperatures has gained enormous popularity. However, an effective way to quantify the geochemical, thermodynamic and electrostatic factors...

Restoring Agency to the Human Actor.

Perspectives on psychological science : a journal of the Association for Psychological Science

Swann WB, Jetten J.
PMID: 28544869
Perspect Psychol Sci. 2017 May;12(3):382-399. doi: 10.1177/1745691616679464.

A cursory read of the social psychological literature suggests that when people find themselves in strong situations, they fail to display agency. The early classic studies of conformity, obedience, and bystander intervention, for example, are renowned for showing that...

The Florence Nightingale Effect: Organizational Identification Explains the Peculiar Link Between Others' Suffering and Workplace Functioning in the Homelessness Sector.

Frontiers in psychology

Ferris LJ, Jetten J, Johnstone M, Girdham E, Parsell C, Walter ZC.
PMID: 26858670
Front Psychol. 2016 Jan 28;7:16. doi: 10.3389/fpsyg.2016.00016. eCollection 2016.

Frontline employees in the helping professions often perform their duties against a difficult backdrop, including a complex client base and ongoing themes of crisis, suffering, and distress. These factors combine to create an environment in which workers are vulnerable...

Optical detection of the Casimir force between macroscopic objects.

Optics letters

Petrov V, Petrov M, Bryksin V, Petter J, Tschudi T.
PMID: 17041670
Opt Lett. 2006 Nov 01;31(21):3167-9. doi: 10.1364/ol.31.003167.

We report the optical detection of mechanical deformation of a macroscopic object induced by the Casimir force. An adaptive holographic interferometer based on a photorefractive BaTiO3:Co crystal was used to measure periodical nonlinear deformations of a thin pellicle caused...

Measurement of the enhanced evanescent fields of integrated waveguides for optical near-field sensing.

Applied optics

Hahn J, Rüter CE, Fecher F, Petter J, Kip D, Tschudi T.
PMID: 18449300
Appl Opt. 2008 May 01;47(13):2357-60. doi: 10.1364/ao.47.002357.

The sensitivity of an integrated optical sensing device can be enhanced by coating it with a high refractive index layer, while both incoupled intensity and spatial resolution are maintained. The potential for enhanced sensing is demonstrated using titanium indiffused...

Release of chromium from orthopaedic arthroplasties.

The open orthopaedics journal

Afolaranmi GA, Tettey J, Meek RM, Grant MH.
PMID: 19461924
Open Orthop J. 2008 Jan 24;2:10-8. doi: 10.2174/1874325000802010010.

Many orthopaedic implants are composed of alloys containing chromium. Of particular relevance is the increasing number of Cobalt Chromium bearing arthroplasies being inserted into young patients with osteoarthritis. Such implants will release chromium ions. These patients will be exposed...

Systemic effector and regulatory immune responses to chlamydial antigens in trachomatous trichiasis.

Frontiers in microbiology

Gall A, Horowitz A, Joof H, Natividad A, Tetteh K, Riley E, Bailey RL, Mabey DC, Holland MJ.
PMID: 21747780
Front Microbiol. 2011 Feb 10;2:10. doi: 10.3389/fmicb.2011.00010. eCollection 2011.

Trachomatous trichiasis (TT) caused by repeated or chronic ocular infection with Chlamydia trachomatis is the result of a pro-fibrotic ocular immune response. At the conjunctiva, the increased expression of both inflammatory (IL1B, TNF) and regulatory cytokines (IL10) have been...

Updating clinical endpoint definitions.

Pulmonary circulation

Hassoun PM, Nikkho S, Rosenzweig EB, Moreschi G, Lawrence J, Teeter J, Meier C, Ghofrani AH, Minai O, Rinaldi P, Michelakis E, Oudiz RJ.

The 6-Minute Walk Distance (6-MWD) has been the most utilized endpoint for judging the efficacy of pulmonary arterial hypertension (PAH) therapy in clinical trials conducted over the past two decades. Despite its simplicity, widespread use in recent trials and...

Thermal Ring Contraction Reactions of 9-Aryl-5H,7H-[1,2,5]thiadiazolo[3,4-h][2,3,4]benzothiadiazepine 6,6-Dioxides. Experimental and Computational Studies for Understanding the Course of the Transformations.

The Journal of organic chemistry

When refluxing with sodium hydrogen carbonate in acetonitrile, 7-chloro-5-(4-fluorophenyl)-1,3-dihydro-2,3,4-benzothiadiazepine 2,2-dioxide afforded, after loss of dinitrogen and subsequent ring contraction, the corresponding sulfone in 83% yield. Similar treatment of the related thiadiazolo-fused tricycles, i.e. 9-aryl-5H,7H-[1,2,5]thiadiazolo[3,4-h][2,3,4]benzothiadiazepine 6,6-dioxides, resulted in a substantially...

Individuals' attitudes about persons with disability (PwD) strongly affect differently-abled persons' quality of life and position in society. Some research offers support for the ability of systematic, supported, longitudinal contact between different groups of individuals to improve attitudes. College...
