Stars near the Sun oscillate both horizontally and vertically. In a previous paper by Binney it was assumed that the coupling between these motions can be modelled by determining the horizontal motion without reference to the vertical motion, and recovering the coupling between the motions by assuming that the vertical action is adiabatically conserved as the star oscillates horizontally. Here, we
This paper proposes a theory of gazelle growth in which gazelles can grow either organically or through acquisitions. The model includes three types of firms: incumbent, target, and gazelle. We show that the lower cost of organic growth can increase the incentives for acquisition growth because the incumbent understands that if it acquires the target firm, the gazelle will then invest organically
Stellar ages are a crucial component to studying the evolution of the Milky Way. Using Gaia DR2 distance estimates, it is now possible to estimate stellar ages for a larger volume of evolved stars through isochrone matching. This work presents [M/H]-age and [α/M]-age relations derived for different spatial locations in the Milky Way disc. These relations are derived by hierarchically modelling the
This paper explores public attitudes towards science and nature in twelve countries using data from the International Social Survey Programme environment modules of 1993, 2000, and 2010. Analysis of attitude items indicates technocentric and pessimistic dimensions broadly related to the Dominant Social Paradigm and New Environmental Paradigm. A bi-axial dimension scale is utilized to classify resp
Since the late 1970s several epidemiological studies have appeared linking exposure to phenoxy herbicides or chlorophenols to some malignant tumors. Most of these compounds are contaminated with dioxins and dibenzofurans; for example, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a contaminant of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), a component of Agent Orange which was sprayed in Vietnam
The present analysis investigates the discursive redefinitions of the folkhem conceptual metaphor, which accommodates centrally located heteronormative masculinities at the intersection of gender, class, and race. It focuses on recent reinterpretations of this conceptual metaphor as heralded by the main Swedish radical right populist party, the Sweden Democrats (SD), and its leader, Jimmie Åkesson
Dispersal distance, measured as the number of territories between place of birth and place of first breeding, was analysed within and between sexes in juvenile marsh tits in relation to factors potentially caiusing variation in dispersal pattern. Dispersal distance of males was positively influenced by both population density and hatching date. In females, dispersal distance were positively relate
The effects evoked by intradermal injections of substance P (SP), neurokinin A (NKA) or calcitonin gene-related peptide (CGRP) were studied in 51 non-atopic subjects. SP and NKA produced flare and weal, and CGRP produced an indurated erythema. The reactions to SP were strong, the flare being maximal 3–5 min after injection and the weal after 10–15 min. NKA evoked a much weaker flare and a slightly
The actions and interactions of putative mediators of inflammation, such as substance P (SP), histamine, bradykinin and prostaglandins (PGE2) were studied in human skin. In addition, the effects of capsaicin were examined as it is known to release (and to deplete) SP and calcitonin gene-related peptide from C-fibres. The flare evoked by bradykinin was abolished by pretreatment with lignocaine (loc
Like many jurisdictions that have implemented a general anti-avoidance tax legislation (GAAR), Swedish tax law faces the challenge of accurately defining the conditions for distinguishing abusive situations from others, especially as the notion of ‘abuse of law’ does not exist in Swedish law. Defined as a process in which a taxpayer follows both the wording of the law and its jurisprudential appli
In 18 untreated adult patients (median age 62.5 yr) with advanced non‐Hodgkin's lymphoma of unfavourable histology, thymidine labelling indices (LIs) of the lymphoma cells were assessed. The patients were treated with combination chemotherapy and have been followed for 29–60 (median 52) months or until death. The survival curve had a steep fall during the first 2 yr. Between 2–5 yr after treatment
In aqueous solution of 1,1'-diethyl-2,2'-carbocyanine J-aggregate, the exciton self-trapped (EST) state is usually expected to be negligible. However, in this work, by measuring transient absorption spectroscopy under a variety of excitation fluences, the EST state was found to be formed via coherent exciton-exciton annihilation (EEA), when the excitation fluence was high enough. With the existenc
Med utgångspunkt i den franske filosofen Michel Foucaults perspektiv och antologin Känslornas revolution, redigerad av Jens Ljunggren presenteras och diskuteras i den här artikeln värdet och utkomsten av att studera och analysera känsloregimer ("emotionologier").
Multiply charged ions are easily formed in rare gases by multiphoton absorption processes. For Kr and Xe up to quadruply charged ions are formed. They are induced by a bandwidth-limited 50 ps laser pulse at 1.064 W cm -2 intensity range. Doubly charged ions are formed through the absorption of a very large number of photons (29 for Xe) in a direct transition from the ground state of the atom to th
We present high-order harmonic generation results obtained with different laser systems a 1 ps 1053 nm Nd-glass laser a 2 ps 616 nm synchronously pumped dye laser a 36 ps 1064 nm mode-locked Nd-YAG laser and the second harmonics (308 nm and 532 nm) of the latter two systems. We investigate the influence of the laser pulse width the excitation wavelength (from the near infrared to the ultraviolet)
Experimental autoimmune encephalomyelitis (EAE) shares similar immunological and clinical features with multiple sclerosis (MS), and is therefore widely used as a model to identify new drug targets for better patient treatment. MS is characterized by several different disease courses: relapsing-remitting MS (RRMS), primary progressive MS (PPMS), secondary progressive MS (SPMS), and a rare progress
