M ost people agree that computer science will play a significant role in the global information society. But what will that role be? Analyzing the part knowledge played in the agrarian, industrial, and information societies—which correspond roughly to the past, present, and future—can help answer this question. In an agrarian society, people provide the main source of energy, in the sense that ...

Digoxin and diuretics were once the cornerstones of therapy for patients with chronic heart failure. During the past 2 decades, an increasing number of therapeutic options for the treatment of symptomatic heart failure has emerged. Demonstrated benefit of these therapies has led to parallel growth of practice guidelines and performance measures. As a result, physicians caring for patients with ...

Aims. Determination and analysis of electron densities and filling factors of the diffuse ionized gas (DIG) in the solar neighbourhood. Methods. We have combined dispersion measures and emission measures towards 38 pulsars at distances known to better than 50%, from which we derived the mean density in clouds, Nc, and their volume filling factor, Fv, averaged along the line of sight. The emissi...

Rare earth metals activated with ca. 2% iodine react directly with 2,6-diisopropylphenol (HOdip) in tetrahydrofuran (thf), 1,2-dimethoxyethane (dme), and dig-dme (dig = di(2-methoxyethyl) ether) to give solvated phenolate complexes [Ln(Odip)(3)(thf)(n)] (Ln = La, Nd, n = 3; Ln = Sm, Dy, Y, Yb, n = 2), [Eu(Odip)(μ-Odip)(thf)(2)](2), [Ln(Odip)(3)(dme)(2)] (Ln = La, Yb) and [La(Odip)(3)(dig)] in g...

BACKGROUND Intraoperative identification of anaplastic foci in diffusely infiltrating gliomas (DIG) with non-significant contrast-enhancement on MRI is indispensible to avoid histopathological undergrading and subsequent treatment failure. Recently, we found that 5-aminolevulinic acid (5-ALA) induced protoporphyrin IX (PpIX) fluorescence can visualize areas with increased proliferative and meta...

We calculate the coupled hydrostatic and ionization structures of spherically symmetric, pressure-supported gas clouds that are confined by gravitationally dominant dark-matter (DM) mini-halos and by an external bounding pressure provided by a hot medium. We focus on clouds that are photoionized and heated by the present-day background metagalactic field and determine the conditions for the for...

The reliability and validity of Digital Stroop Test (Dig. Str.) that was developed for a screening test the executive function were evaluated by two studies. Dig. Str. to evaluate both effect Reverse using computer tablet. In Study 1, test-retest paradigm. High correlations between scores (mean response time per correct response) on tests obtained. 2, construct examined sample healthy old-aged ...
