A presentation of three ab initio atomic structure calculation projects

Three theoretical atomic structure projects of interest for the astrophysical community and the lightning industry which are partially finished will be presented. Extensive ab initio calculations of properties of astrophysical interest has been done or are under its way for Ga I, Ga II, Ga III, In II and In III. The aim of the project is to also make calculations for In I, Tl I, Tl II and Tl III.

Impact on long-term mortality of presence of obstructive coronary artery disease and classification of myocardial infarction.

In contrast to the associated with thromboembolic event type 1 myocardial infarction, type 2 myocardial infarction is caused by acute imbalance between oxygen supply and demand of myocardium. Type 2 myocardial infarction may be present in patients with or without obstructive coronary artery disease, but knowledge about patient characteristics, treatments, and outcome in relation to coronary artery

Titration of fatty acids solubilized in cationic and anionic micelles. Calorimetry and thermodynamic modeling

The electrostatic properties of charged surfactant micelles are investigated through titrations of fatty acid probes solubilized in the micelles. The titration process is followed by means of calorimetric measurements and by determining the pH values as a function of added base. This approach yields a complete thermodynamic description of the titration process. In particular, we find that the proc

Characterisation of gallium(III)-acetate complexes in aqueous solution: A potentiometric, EXAFS, IR and molecular orbital modelling study

The aqueous gallium(III)-acetate system was studied in 0.6 M Na(Cl) at 25 degreesC using a multi-technique approach, including potentiometry, IR spectroscopy, EXAFS spectroscopy and molecular orbital calculations. The potentiometric data were satisfactorily explained by a model which includes one mononuclear and one binuclear complex. The corresponding equilibrium constants defined according to th

Hydrophobicity and counterion effects on the binding of ionic surfactants to uncharged polymeric hydrogels

Gel swelling experiments have been used to study the binding of ionic surfactants to a series of nonionic alkylacrylamide hydrogels of increasing hydrophobicity. The binding of hexadecyl trimethylammonium (C-16-TA(+)) to uncharged gels is sensitive to both the hydrophobicity of the gel and the counterion to the surfactant. There is a minimum hydrophobicity threshold below which binding of the surf

Seediq – antisymmetry and final particles in a Formosan VOS language

This paper presents data from the Austronesian language Seediq, spoken in taiwan, which has both VOS order and final particles. It will be argued that the coccurrence of these two features is unexpected under a pre-antisymmetric analysis, whereas it is easily captured under an analysis couched in Kayne's Antisymmetry model, under the assumption that VOS order is derived by raising the predicate to

Internal water molecules and magnetic relaxation in agarose gels

Agarose gels have long been known to produce exceptionally large enhancements of the water H-1 and H-2 magnetic relaxation rates. The molecular basis for this effect has not been clearly established, despite its potential importance for a wide range of applications of agarose gels, including their use as biological tissue models in magnetic resonance imaging. To resolve this issue, we have measure

The innate immune response differs in primary and secondary salmonella infection.

This study examines innate immunity to oral Salmonella during primary infection and after secondary challenge of immune mice. Splenic NK and NKT cells plummeted early after primary infection, while neutrophils and macrophages (M{phi}) increased 10- and 3-fold, respectively. In contrast, immune animals had only a modest reduction in NK cells, no loss of NKT cells, and a slight increase in phagocyte

Role of p190RhoGAP in beta(2) integrin regulation of RhoA in human neutrophils

We found that engagement of beta (2) integrins on human neutrophils induced activation of RhoA, as indicated by the increased ratio of GTP:GTP + GDP recovered on RhoA and translocation of RhoA to a membrane fraction. The clustering of beta (2) integrins also induced a time-dependent increase in GDP bound to RhoA, which correlated with beta (2) integrin-induced activation of p190RhoGAP. The activat

Particle emission time sequence in intermediate energy heavy ion reactions

The CHIC Collaboration has performed a series of simultaneous pp, np and nn fermion interferometry experiments in order to study the space-time evolution of the emission sources in intermediate energy heavy ion reactions. Furthermore, when correlations of non-identical particles are available, additional model independent information on the emission chronology of the particles is obtained. In this

Feasibility of noninvasive transthoracic echocardiography/Doppler measurement of coronary flow reserve in left anterior descending coronary artery in patients with acute coronary syndrome: A new technique tested in clinical practice

Objective: The aim of this study was to test the feasibility and accuracy of transthoracic Doppler echocardiography measurement of coronary flow reserve (CFR) in the left anterior descending coronary artery (LAD) territory in the clinical setting of the acute coronary syndrome. Methods: Transthoracic Doppler echocardiography measurements of CFR were made in 42 consecutive patients in the distal LA

Reswelling of polyelectrolyte hydrogels by oppositely charged surfactants

The interactions between charged alkylacrylamide gels of varying hydrophobicity and charge density and the oppositely charged surfactant hexadecyltrimethylammonium (C(16)TA(+)) have been investigated to determine the conditions necessary to induce excess surfactant binding (beyond charge neutralization) and resolubilization of the polymer-surfactant complex. In all cases, an initial gel collapse o
