The Rydberg formula is emblematic of atomic spectroscopy. We review here the personal background, research accomplishments, and academic career of its discoverer, Janne Rydberg. Although his formula is often introduced as a generalization of the hydrogenic Balmer formula, Rydberg’s work was independent of Balmer’s, and displayed great ingenuity and a rare ability to recognize hidden patterns in co
The thesis presents the author s research on numerical methods for Com-putational Aeroacoustics and the development of computational tools with direct applicability in industry. The designers in the gas-turbine industry, require accurate methods for predicting the onset and the frequencies of dangerous (pressure) oscillations, like the ones which typically occur in Lean Premixed Pre-vaporized (LPP
The Ax phenotype is an important subgroup of the ABO blood group system. Its inheritance does not always follow Mendelian rules and recent studies suggested that different alleles can result in this phenotype. This suggestion has been explored by cloning and sequencing exons 6 and 7 of the ABO gene and the intervening intron from members of six unrelated families expressing the Ax phenotype. Two f
On 7 December 1975 Indonesian troops invaded the former Portuguese colony of East Timor, which had unilaterally declared itself independent on 28 November the same year. The immediate background to the Indonesian invasion of East Timor was that the old regime in Portugal was overthrown in April 1974, resulting in a decolonisation programme for Portugal's colonies. Immediately after the invasion In

After a long period of stagnation, Syria during the nineteenth century arose to a cultural and social renaissance. One important field of development was education. An article published in Beirut in 1883 sheds important light on this. External impulses were important, but much of the development effort was indigenous. There were significant differences in the level of education between towns and t
The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1.6 litre single cylinder engine based on a heavy duty six cylinder Volvo, was used for the tests. As follows the experimental work was
This article examines the genetic relationships among 34 MSS suspected of being related because of a peculiar shared reading in John 8:8b-9a: "he wrote on the ground the sins of each..." A quantitative analysis detected several independent families, including new family P members and a dozen MSS forming "family Patmos/M;" this family, in turn, includes the original Patmos family discovered by Silv
Synaptotagmins (Syts) are involved in Ca2+-dependent insulin release. However, which Syt isoform is functional in primary beta-cells remains unknown. We demonstrate by electron microscopy of pancreatic islets, the association of Syt 9 with insulin granules. Silencing of Syt 9 by RNA interference adenovirus in islet cells had no effect on the expression of Syt 5, Syt 7 and Syt 3 isoforms. The latte
It is becoming increasingly clear that conditions experienced during embryonic development can be of major importance for traits subsequent to parturition or hatching. For example, in mammals, offspring from stressed mothers show a variety of changes in behavioural, morphological, and life-history traits. The effects of maternal stress on trait development are believed to be mediated via transfer
This cross-sectional study was done in order to ascertain whether there is a lifelong beneficial effect on bone mineral density (BMD) of early, long-lasting, and intense physical exercise. Forty-eight male ex-weight lifters, mean age 64 years (range 50-79) participated. They had followed a training program of an average of 10 hours/week (range 4-20) for an average of 13 years (range 1-34). They ha
In the previous study, we investigated effect of physical state of nonpolar lipids of gluten-starch model dough. This experiment examined a real wheat flour dough system to assess the role of fat crystals in the breadmaking processes. These experiments were performed with a baking test and an investigation of wheat flour dough through rheological measurements (both large and small deformations), s
The theme of men and women is conspicuous in T. S. Eliot's early poetry. It constitutes the subject of this study, which is an investigation of the symbolic images, metaphors and similes associated with this theme. When a man/woman relationship is referred to, the relevant imagery is often taken from historical or mythical narratives, suggesting an element of universal applicability. Painful feeli
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
