Single frequency erbium fiber external cavity semiconductor laser
No full textA novel external cavity configuration for stable single frequency operation of the semiconductor laser is demonstrated. By using an erbium doped fiber as the external cavity, longitudinal mode-hopping is suppressed, ensuring single frequency operation. Employing a 3m long fiber cavity, resolution-limited optical linewidths of a kHz are obtained.[This article may be downloaded for personal use only.

Dynamic analysis of structures on multicore computers:Achieving efficiency through object oriented design
No full textThe paper examines software design aspects of implementing parallel and distributed computing for transient structural problems. Overall design is achieved using object and component oriented methods. The ideas are implemented using .NET and the Task Parallel Library (TPL). Parallelisation and distribution is applied both to single problems, and to solving multiple problems. The use of object-oriented design means that the solvers and data are packaged together, and this helps facilitate distributed and parallel solution. Factory objects are used to provide the solvers, and interfaces are used to represent both the factory objects and solvers
Suitability of empirical equations for estimating permanent settlement of railway foundation materials subject to cyclic loading with principal stress rotation
No full textThis paper uses the results of a series of laboratory tests with cyclic principal stress rotation to assess the suitability of a number of empirical equations for estimating the development of plastic settlements in railway track foundations. The laboratory tests were carried out on three sand-clay mixes representative of railway track foundation materials, in both free-to-drain and undrained conditions. The results of a non-linear regression analysis demonstrate that the drainage conditions are the key factor affecting the estimation accuracy of the models, with the clay content playing a secondary role. The correlation coefficient was generally higher in free-to-drain than in undrained conditions, and reduced slightly with increasing clay content.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Lokalne zróżnicowanie parametrów wiatru na Mierzei Łebskiej (Słowiński Park Narodowy)
No full textThe daily course of wind speed and direction over chosen active surfaces close to the sea shore on the Łeba Bar have been analysed. Measurements took place in the vicinity of the field station of the Department of Climatology, Adam Mickiewicz University in the period from the 1st of July until 25th of August 2009. Two measurement posts, representing different morphological and plant zones were chosen: 1) the frontal dune, 2) coniferous forest, and additionally, the measurements from an automatic meteorological station, located at the grey dune in the topographic low behind the frontal dune, were used. The daily cycle of wind speed changes, with its maximum in the early afternoon and minimum at night, was identified at both measurement posts. Wind speed decreases towards the land interior. The difference of a few hundred meters distance from the sea shore between posts 1 and 2 causes substantial decrease in wind speed. Additionally, the topography of the second post, which is located in the forest, in the depression behind the frontal dune, strongly reduces wind speed. The breeze circulation was weak during the measurement period while the macroscale western circulation was dominant with shorter periods when the eastern flow dominated. The effect of the night breeze was expressed by southern deviation of wind direction and the daily breeze in the afternoon, whereas in the evening the northern directions dominated.A6111912

Optical spectroscopy of the low-mass X-ray binary GX 9+9
No full textPhase-resolved medium-resolution VLT spectroscopy of the low-mass X-ray binary GX 9+9 has revealed narrow C ill emission lines that move in phase relative to our new estimate of the ephemeris, and show a velocity amplitude of 230 +/not superset of 35 km s(-1). We identify the origin of these lines as coming from the surface of the donor star, thereby providing the first estimate of the mass function of f(M-1) >= 0.22 M-circle dot. Rotational broadening estimates together with assumptions for the mass donor give 0.07 <= q <= 0.35 and 182 <= K-2 <= 406 km s(-1). Despite a low-mass ratio, there is no evidence for a superhump in our data set. Doppler maps of GX 9+9 show the presence of a stream overflow, either in the form of material flowing downward along the accretion disc rim or in a similar fashion as occurs in high mass transfer rate cataclysmic variables known as the SW Sex stars. Finally, we note that the Bowen region in GX 9+9 is dominated by C in instead of N III emission as has been the case for most other X-ray binaries
Measuring equity in health care financing - reflections on (and alternatives to) the World Health Organization's fairness of financing index
No full textIn its latest World Health Report, The World Health Organization (WHO) argues that a key dimension of a health system's performance is the fairness of its financing system. The report discusses how policymakers can improve this aspect of performance, proposes an index of fairness, discusses how it should be put into operation, and presents a league table of countries, ranked by fairness with which their health services are financed. The author shows that the WHO index cannot discriminate between health financing systems that are regressive, and those that are progressive - and cannot discriminate between horizontal inequity, and progressiveness, or regressiveness. The index cannot tell policymakers whether it deviates from 1 (complete fairness) because households with similar incomes spend different amounts on health care (horizontal inequity), or because households with different incomes spend different proportions of their income on health care (vertical inequity, given the WHO's interpretation of the ability-to-pay principle) - although the two have different policy implications. With the WHO's index, progressiveness, and regressiveness are both treated as unfair. This makes no sense, because policymakers who may be strongly averse to regressive payments (which worsen income distribution) may in the name of fairness be quite receptive to progressive payments (requiring that the better-off, who may be willing to spend proportionately more on health care, are required to pay proportionately more). The author compares the WHO index with an alternative, and more illuminating approach developed in the income redistribution literature in the early 1990s, and used in the late 1990s, to study the fairness of various OECD health care financing systems. He illustrates the differences between the approaches with an empirical comparison, using data on out-of-pocket payments for health services in Vietnam for 1993 and 1998. This analysis is of some interest in its own right, given the large share of health spending from out-of-pocket payments in Vietnam, and the changes in fees, and drug prices over the 1990s.
The two Ephesian matrons: Drusiana’s story in the Acts of John as a possible Christian response to Milesian narrative
No full textIn this paper I try to demonstrate that the literary tradition of fabula Milesia
might lie in the background of both Petronius’ tale of the Milesian matron
and the story of Drusiana, told in the apocryphal Acts of John. This view is
supported by some elements common to the two stories: the location in
Ephesus; the theme of virtue, causing the women to long for death; the place
– a tomb – where their fidelity is put to test; and above all, the motif of return to life. And, if Petronius reflects the profane Milesian tradition, the author of the AJ criticizes it, aiming at re-using it to teach Christian morality
