The optical spectra of a quantum cascade laser structure under nonequilibrium conditions is studied using the technique of nonequilibrium Green functions. We focus on the impact of Coulomb corrections and their dependence on the operating conditions. The role of the static mean field due to the charge distribution by electrons and ioninzed donors is investigated.

Low or reduced energy availability (LEA) is linked to functional hypothalamic oligomenorrhea/amenorrhea (FHA), which is frequently reported in weight-sensitive sports. This makes LEA a major nutritional concern for female athletes. The aim of this study was to describe dietary characteristics of athletes with LEA and/or FHA. Endurance athletes (n = 45) were recruited from national teams and compet

The menisci play a critical protective role for the knee joint through shock absorption and load distribution. Currently, the consensus in surgical treatment of meniscal tears is to preserve as much functional meniscal tissue as possible. The health professional is challenged to choose the best treatment, both in the short- and in the long-term. A degenerative lesion in the middle-aged or older pa

l-DOPA is the most commonly used treatment for symptomatic control in patients with Parkinson's disease. Unfortunately, most patients develop severe side-effects, such as dyskinesia, upon chronic l-DOPA treatment. The patophysiology of dyskinesia is unclear; however, involvement of serotonergic nerve fibers in converting l-DOPA to dopamine has been suggested. Therefore, potassium-evoked dopamine r

Review of Patrich Hamm's bok Die Diva ist ein Mann. Das grosse Tuntenbuch (Berlin: Querverlag, 2007)

We report on lifetime measurements of the 3d(5)(S-6)4s4p(P-3)y P-6 degrees states of Fe II using time-resolved vacuum ultraviolet (VUV) laser spectroscopy. A laser-produced plasma has been used as the source of free Fe+ ions. The tunable VUV radiation was obtained employing resonantly enhanced sum-difference four-wave-mixing of short laser pulses. We obtained tau((6)P(3/2)degrees) = 3.90(20) ns, t

Popular Abstract in Swedish Nuförtiden är det tryckta bokomslaget en självklar del av boken som produkt och konsumentvara. I avhandlingen studeras etableringen av bokomslaget och dess betydelse för omstruktureringen av bokmarknaden i Sverige decennierna kring 1800. Från mitten av 1700-talet blev den färdigbundna boken en betydelsefull del av bokhandelns utbud. Förlag och bokhandel började sälja deThe aim of the dissertation is to examine the significance of the paperbound book on the book market as part of the history of consumption. It is an examination of the materiality of the book, in which the form and function, economics and distribution of the binding during the last century of the hand-press era are studied. The intention has been to show that the ready-bound book was a means for t
