Rufous-collared sparrows (Zonotrichia capensis peruviensis) from valleys in the Atacama Desert of Chile, live in an extremely stable environment, and exhibit overlap in molt and reproduction, with valley-specific differences in the proportion of birds engaged in both. To better understand the mechanistic pathways underlying the timing of life-history transitions, we examined the relationships amon
Purpose To explore demand related information sharing in a multi-tier supply chain and propose contingency factors that impact benefits of information sharing across three or more tiers. Design/methodology/approach Through an in-depth case study a range of methods are used to collect data from companies representing three different tiers, including focal company, 1st tier suppliers and 1st tier c
Popular Abstract in Swedish Studien handlar om fysiologen Frithiof Holmgrens försök att fastställa seendets natur på experimentell väg. Avsikten är att problematisera Holmgrens intresse för synsinnet mot bakgrund av de metoder och vetenskapliga ideal som var förhärskande inom den experimentella fysiologin, det ämne som Holmgren introducerade i Sverige 1862. Generellt kan man säga att Holmgrens forThis study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. By opposing the natural philosophical and vitalistic viewpoint of romantic medicine and by proclaiming measuring devices, animal
Chronic suppurative otitis media often ensues in patients treated with irradiation against a head and neck tumor. In an experimental study, rats were exposed to irradiation to evaluate the sensitivity of the middle ear to an accumulated irradiation dose of 20-45 Gy. Observed otomicroscopically, all animals appeared to have normal tympanic membranes and no fluid developed in the middle ear space. T
Syftet med denna avhandling har varit att undersöka tvångsvårdens legitimitet. För det ändamålet har jag genomfört, spelat in och transkriberat kvalitativa intervjuer med 80 klienter – som var föremål för LVM-vård våren 2006 – samt deras socialsekreterare när klienterna dels var intagna på LVM-hem och dels vid en uppföljning cirka sex månader efter tvångsvårdens slut. Avhandlingen utgår från fem The aim of this dissertation was to examine the legitimacy and the legitimizing of compulsory care for substance abusers according to LVM. For this purpose I have conducted, recorded and transcribed qualitative interviews with 80 clients – taken into such care in spring 2006 – and their social welfare officers when the clients were in compulsory care and then again about six months after its termi
Popular Abstract in Swedish Denna avhandling fokuserar förändringar inom den arbetsmarknadspolitik som erbjuds arbetslösa socialbidragstagare mellan 1989 och 2002 i Sverige. Denna förändring beskrivs som en process där kommunerna tar allt mer ansvar för arbetsmarknadspolitiken. Denna grupp arbetslösa kategoriseras som en speciellt problematisk grupp och hänvisas till kommunerna. Detta sker utan tyThis dissertation focuses on changes in labour market policies that were provided for unemployed recipients of social assistance between 1989 and 2002 in Sweden. This change is described as a process where the municipalities gradually take greater responsibility for the labour market policies. This group of unemployed is categorized as a particularly problematic group and has been referred to the
Hexokinase 2 (Hxk2p) from Saccharomyces cerevisiae is a bi-functional enzyme being both a catalyst and an important regulator in the glucose repression signal. In the presence of xylose Hxk2p is irreversibly inactivated through an autophosphorylation mechanism, affecting all functions. Consequently, the regulation of genes involved in sugar transport and fermentative metabolism is impaired. The ai
Objective. To assess the impact of low-to-moderate risk prostate cancer on patients' quality of life (QoL) at diagnosis and within the first year of treatment. Subjects and Methods. Men (n = 672) aged 50-75 years with prostate cancer (Gleason score ≤7, PSA ≤20 ng/mL and clinical staging T1c-T2b) were enrolled in five European countries. Patients completed five questionnaires, including EORTC Quali
Dose calculations for treatment planning of photon beam radiotherapy require a model of the beam to drive the dose calculation models. The beam shaping process involves scattering and filtering that yield radiation components which vary with collimator settings. The necessity to model these components has motivated the development of multisource beam models. We describe and evaluate clinical photo
Polychlorinated biphenyls (PCBs) and organic pesticides (i.e., DDTs) were measured in long finned eels (Anguilla dieffenbachii) in 17 streams on the west coast of South Island, New Zealand. Very low levels of PCBs and low levels of ppDDE were found. The concentrations of PCBs and ppDDE were not correlated within sites indicating that different processes determined the levels of the two pollutants
We present measurements of isothermal DNA-hexadecyltrimethylammonium (DNACTA) complex and pure DNA hydration at 25 degreesC using a sorption microcalorimeter. This calorimeter provides simultaneous measurement of (i) water activity (sorption isotherms) and (ii) the partial molar enthalpy of water as a function of water uptake. For pure DNA, hydration is exothermic over the studied concentration ra
Since many years, life charting has been used to describe the life course and life events of psychiatric patients. The aim of the present study was to describe and evaluate time geographic life. charts of 11 former psychiatric patients in order to promote systematic descriptions of their life events over time. Information on all events which was gathered from the life charts was analysed by manife
The purpose of this study was to evaluate the effect of dose reduction in digital mammography on the detection of two lesion types-malignant masses and clusters of microcalcifications. Two free-response observer studies were performed-one for each lesion type. Ninety screening images were retrospectively selected; each image was originally acquired under automatic exposure conditions, correspondin
Dramatic swings in the North Atlantic oscillation (NAO) during the 1990s motivated the authors to build a statistical model of NAO impacts on hydropower production and energy markets in Scandinavia. Variation in the NAO index is shown to explain 55% of the variance of streamflow in Norway and up to 30% of the variance in Norway's hydropower output. It is also possible to identify the influence of
Popular Abstract in Swedish Hur löser den intellektuelle politikern problem och hur skapas kontakten med den politiska omgivningen? Svaren på frågorna skall kortfattat presenteras och är intressanta för politiker, partier, väljare och forskare. Svaren visar nämligen hur intellektuella politiker under kristider producerar och presenterar innovativa lösningar som kan få stor betydelse för samhällsutA new theory on the intellectual politician, which has the ability to produce a designed type of problem-solving, has been developed from political science theory, cognitive theory as well as art theory. A cognitive concept, modified integrative complexity, consisting of four sub-concepts, frame reflection, differentiation, reframing and integration has been developed. The relation between politic
The St Louis aerosol was sampled during the period 16-22 August 1973 simultaneously at two locations using cascade impactors for sequential 12-hour samples. The six particle size fractions of each sampling were individually analyzed using PIXE for elements from S to Br and beyond and for heavy elements including Pb which permitted time variations of concentrations and particle size distributions t
Due to the increasing interest of producing power from renewable and non-conventional resources, organic Rankine cycles are finding their place in today’s thermal energy mix. The main influencers on the efficiency of an organic Rankine cycle are the working fluid and the expander. Therefore most of the research done up to date turns around the selection of the best performance working media and th
