Purpose. To evaluate aqueous humor MMP-9 levels in alkali-burned rabbit cornea following KPr implantation and their roles in RPMs formation. Methods. Left eyes of 36 rabbits received a deep corneal alkali wound. 12 corneas were implanted with KPro and the other 24 control corneas were either penetrating keratoplasty or left without keratoplasty. Aqueous humor MMP-9 and TIMP-1 levels were determ...

A complete understanding of both the steady state and transient background measured by Radiation Portal Monitors (RPMs) is essential to predictable system performance, as well as maximization of detection sensitivity. To facilitate this understanding, a test bed for the study of natural background in RPMs has been established at the Oak Ridge National Laboratory. This work was performed in supp...

OBJECTIVE: To find the effect of iron deficiency anemia (IDA) on intelligence quotient (IQ) in school going children Peshawar, Pakistan. METHODS: In this cross-sectional study a total 153 (male and female) age 7-11 years were included. Socio-demographic questionnaire was designed for collection data. Blood specimens collected ethylenediaminetetraacetic acid (EDTA) gel tubes. Complete blood coun...

John Raven is Boyd Baxter Professor of Biology at the University of Dundee. He studied botany at the University of Cambridge, and stayed on for a PhD in plant biophysics with an exceptionally insightful scientist and mentor, Professor Enid MacRobbie. His research at Dundee is centred on how organisms acquire and manipulate resources from their environment with particular emphasis on photosynthe...

A four stage semi-pilot scale RFR reactor with ceramic disks as support for TiO₂ modified with silver particles was developed for the removal of organic pollutants. The design presented in this article is an adaptation of the rotating biological reactors (RBR) and its coupling with the modified catalyst provides additional advantages to designs where a catalyst in suspension is used. The optima...

The problem of successfully simulating ionic fluids at low temperature and low density states is well known in the simulation literature: using conventional methods, the system is not able to equilibrate rapidly due to the presence of strongly associated cation-anion pairs. In this paper we present a numerical method for speeding up computer simulations of the restricted primitive model (RPM) a...

First, though the Draft Guidelines appear to apply a “rule of reason” or effects-based approach to most vertical restraints, Part I.3 and Part I, Chapter 1 carve out resale price maintenance (RPM) practices on the ground that they “usually have significant anticompetitive effects and, as a general rule, they tend to impede fair competition.” Given the economic theory and empirical evidence show...

The modified rotating simplex method has been successfully used to determine the best combination of agitation rate and aeration rate for maximum production of extracellular proteases by Staphylococcus aureus mutant RC128, in a stirred tank bioreactor operated in a discontinuous way. This mutant has shown altered exoprotein production, specially enhanced protease production. Maximum production ...

PURPOSE To optimize endurance cycling performance, it is important to maximize efficiency. Power-measuring cranks and force-sensing pedals can be used to determine the mechanical effectiveness of cycling. From both a coaching and basic science perspective, it is of interest if a mechanically effective pedaling technique leads to greater efficiency. Thus, the purpose of this study was to determi...

We hypothesized that use of a true 3D display providing easy visualization of patient anatomy and dose distribution would lead to the production of better quality radiation therapy treatment plans. We report on a randomized prospective multi-institutional study to evaluate a novel 3D display for treatment planning.The Perspecta Spatial 3D System produces 360 degrees holograms by projecting cros...
