Monl torlng of trace gases in the atmosphere has been performed wl th differential absorption lldar and differential optical absorption spectroscopy. A new mobile differential absorption lldar system has been constructed. It is described in detail and examples of 502 and N02 measurements are given. Studies of the N02 concentration distribution in an urban area during a temperature inversion were p
Abstract in SpanishEste texto responde a una necesidad izquierdista, pero de una izquierda que por razones obvias ya no se encuentra. Trata de buscar todas las respuestas; de no renunciar a una visión compleja pero global, capaz de transformase en una “guía para la acción”. Se trata de un texto con respuestas, planes, ideas claras, objetivos, convicciones. Hasta hace no muchos años, el mundo era r
A comparison between second language learners of Swedish, some of whom have an L1 with lexical tones, while the others do not, and their ability to produce adequate tonal word accents in Swedish is presented. The L1s in question are Farsi, Somali, Vietnamese and Thai. There is no clear evidence that it is easier to learn the correct Swedish word accent patterns and their correct application for sp
Wealth is highly correlated between parents and their children; however, little is known about the extent to which these relationships are genetic or determined by environmental factors. We use administrative data on the net wealth of a large sample of Swedish adoptees merged with similar information for their biological and adoptive parents. Comparing the relationship between the wealth of adopte
This essay deals with the film trailers advertising the films in the Lord of the Rings cycle after J. R. R. Tolkien's famous novel: The Fellowship of the Ring, The Two Towers, and The Return of King. This cycle of films proved to be one of the most profitable media ventures so far in the twenty-first century. This financial success was secured by the films adhering to the modern aesthetic of High
One of the key questions in todays galaxy research is the formation and evolution of disk galaxies such as the Milky Way. Using observations in the intermediate band Stromgren uvby filter system we have investigated how both density and metallicity varies within the Galactic disks in order to learn more about the Galaxy and its past. As a first step we test the abilities of the Stromgren photomet
Piety and Modernity examines the dynamics fo religious reform from the point of view of piety and devotional life between 1780 and 1920 in Britain, Ireland, Scandinavia, Germany, and the Low Countries. The "long" nineteenth century saw the introduction of devotional organizations as a means of channeling popular religion. This era also witnessed the translation and publication of devotional books
The blade-tip region encounters high thermal loads because of the hot gas leakage flows. A common way to cool blade tips is to design serpentine passages with 180 degrees turn with the blade-tip walls inside the turbine blades. Improved internal convective cooling is therefore required to increase blade-tip lifetime. This chapter summarizes the heat transfer enhancement of an internal blade-tip wa
The database of photographic meteor orbits of the IAU Meteor Data Centerin Lund has gradually been updated. The version 2001, which has beenprepared for distribution and which will be released soon, containscomplete orbital and geophysical data on 4581 meteors (equinox J2000.0).A new meteor identification code consisting of the publication serialnumber, the author or station code and number of the
Vi är alla goda liberaler numera och tror på medborgerliga friheter och individens självbestämmande. Men hur ser liberalismen som distinkt politiskt alternativ egentligen ut? Att vara liberal är något mer specifikt än att gilla yttrandefrihet och tolerans. Liberalismen behandlas här som en politisk filosofi - en teori om det rättvisa samhället. Olika liberala riktningar diskuteras utifrån de grund
