INTRODUCTION Many studies have examined the health problems among survivors of disasters, showing that the most frequently reported symptoms after disasters are mental health problems, such as posttraumatic stress symptoms, depression, and anxiety (1, 2). In the last decade, the Netherlands was struck by a few national disasters. On October 4, 1992, an El Al Boeing 747 airplane crashed into two...

Balanced incomplete-block designs (BIBDs) with repeated blocks are studied and constructed. We continue work initiated by van Lint and Ryser in 1972 and pursued by van Lint in 1973. We concentrate on constructing (v, b, r, k, λ)-BIBDs with repeated blocks, especially those with gcd(b, r, λ) = 1 and r ≤ 20. We obtain new bounds for the multiplicity of a block in terms of the parameters of a BIBD...

I visited Van der Horst's clinic. He struck me as much more alert than Bouman, and is, I gather, more popular with the students. The researches of which he told me were concerned with electrical reactions in cats that were being treated with insulin, and the neurological findings in their hypothalamus; also the effect on neurotics of air of different ionic concentration, humidity etc. I gathere...

Background: Bacteremia due to Enterococcus faecalis is usually caused by strains resistant to most antibiotics. Effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. The aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococc...

the ultrasonic velocity, density and viscosity of some schiff bases of 4-amino benzoic acid  were measured in 1,4-dioxane and dimethylformamide at 308.15 k. various acoustical properties such as isentropic compressibility (ks), rao’s molar sound function (rm), the van der waals constant (b), molar compressibility (w), inter molecular free length (lf), relaxation strength (r), internal pressure ...
