STUDY OBJECTIVES To determine the predictive accuracy of pH for identifying patients with malignant pleural effusions who will fail pleurodesis. DESIGN Analysis of published and unpublished individual patient-level data retrieved from a MEDLINE search and correspondence with primary investigators. STUDY SELECTION Studies that reported pleural fluid pH values and outcomes of pleurodesis for ...

The pH dependence of the equilibrium and kinetics of ligand binding to carp hemolysate and the purified hemoglobin components of carp hemolysate with O2 and CO has been studied. The af%nity of carp hemoglobin for O2 at alkaline pH is 160 times that at acid pH. A large but significantly different pH effect on the affinity for CO is observed. pH also has different effects on the kinetics of the r...

AIM Early prediction of prognosis after out-of-hospital cardiac arrest (OHCA) remains difficult. High blood lactate or low pH levels may be associated with poor prognosis in OHCA patients, but these associations remain controversial. We compared blood lactate and pH levels in OHCA patients transferred to our hospital to measure their prognostic performance. METHODS We investigated the associa...

SUBORDINATE-SUPERVISOR DEMOGRAPHIC AND PERCEIVED VALUESIMILARITY: RELATIONSHIPS TO SUBORDINATE PERCEPTIONS OFORGANIZATIONAL JUSTICEby CHARLES LEVI WELLS, IVMay 2013Advisor:SebastianoFisicaro, Ph.DMajor: Psychology (Industrial/Organizational)Degree: Doctor of PhilosophyThe purpose of this study was to examine the empirical relationship between subordinate-...

Let Ph be a self-adjoint semiclassical pseudodifferential operator on a manifold M such that the bicharacteristic flow of the principal symbol on T ∗M is completely integrable and the subprincipal symbol of Ph vanishes. Consider a semiclassical family of eigenfunctions, or, more generally, quasimodes uh of Ph. We show that on a nondegenerate rational invariant torus, Lagrangian regularity of uh...

The growing field of ocean acidification research is concerned with the investigation of organism responses to increasing pCO2 values. One important approach in this context is culture work using seawater with adjusted CO2 levels. As aqueous pCO2 is difficult to measure directly in smallscale experiments, it is generally calculated from two other measured parameters of the carbonate system (oft...

Introduction It is known that intestinal intramucosal pH (pHi) is a good parameter of tissue perfusion in critical patients. However, physiological meaning of pHi value related to other physiological parameter, such as stress hormone, is not well known. The purpose of the study is to clarify the importance of monitoring pHi during hemorrhagic shock in pig model. The relation between pHi, oxygen...

In this article, we study conditional heteroskedasticity in a market index on the Bombay Stock Exchange, from April 1979 to March 1995. We nd strong evidence of heteroskedasticity in daily, weekly and monthly returns. The conditional variance of all three data series seem best approximated by a garch(1,1) model. The garch parameter estimates at all data frequencies exhibit strong persistence in...

The critical micelle concentration (cmc), the surface excess (Γ), as well as the micelle aggregation number (m) of the surfactant dodecyldimethylamine oxide (C12DMAO) have been reported to strongly depend on the pH-value of the aqueous surfactant solution. At high ionic strength, the cmc displays a minimum, while both Γ and m have a maximum at a pH-value close to the pKa of the surfactant. Thes...

Buium proved what he called the abc theorem for abelian varieties over function fields in characteristic zero [3]. Using methods of algebraic model theory we prove an analog of his theorem for commutative algebraic groups in characteristic p. In what follows, k is an algebraically closed field of characteristic p, C is a smooth projective curve over k, and K = k(C) is the function field of C. I...
