Trading off safety against food : state dependent habitat choice and foraging in crucian carp
The influence of hunger level and predation risk on habitat choice and foraging in crucian carp, Carassius carassius, were studied in a laboratory experiment. Experiments were carried out in aquaria with or without a predator (pike, Esox lucius). Habitat use and foraging activity of three-fish foraging groups of either fed or hungry crucian carp were studied. Fish were allowed to choose between an
4. EFFECTS ON LIVER LIPIDS AND LIPOPROTEIN LIPASE ACTIVITY OF ADIPOSE TISSUE IN RELATION TO DIETARY LIPIDS
Prolonged administration of ethanol to young, healthy volunteers : effects on biochemical, morphological and neurophysiological parameters.
A DNS Study of Sensitivity of Scaling Exponents for Premixed Turbulent Consumption Velocity to Transient Effects
3D Direct Numerical Simulations of propagation of a single-reaction wave in forced, statistically stationary, homogeneous, isotropic, and constant-density turbulence, which is not affected by the wave, are performed in order to investigate the influence of the wave development on scaling (power) exponents for the turbulent consumption velocity UT as a function of the rms turbulent velocity u′, lam
Semiempirical breakdown curves of C2N(+) and C3N(+) molecules; application to products branching ratios predictions of physical and chemical processes involving these adducts
We constructed semiempirical breakdown curves (BDC) for C2N, C3N, C2N+ and C3N+ molecules. These BDC, which are energy dependent dissociation branching ratios (BR) curves, were used to predict products branching ratios for various processes leading to the formation of C2N(+) and C3N(+) excited adducts. These processes, of astrochemical interest, are neutral-neutral and ion-molecule reactions, diss
The DENOVA score efficiently identifies patients with monomicrobial Enterococcus faecalis bacteremia where echocardiography is not necessary
Objectives: Enterococcal bacteremia can be complicated by infective endocarditis (IE) and when suspected, transesophageal echocardiography (TEE) should be performed. The previously published NOVA score can identify patients with enterococcal bacteremia at risk for IE and we aimed to improve the score. Methods: Factors associated with IE were studied retrospectively in a population-based cohort of
New elegant methods for maternal and fetal HPA-1a typing
Learning to teach STEM disciplines in higher education : a critical review of the literature
Enrolments in STEM disciplines at universities are increasing globally, attributed to the greater life opportunities open to students as a result of a STEM education. But while institutional access to STEM programmes is widening, the retention and success of STEM undergraduate students remains a challenge. Pedagogies that support student success are well known; what we know less about is how unive
Academic Achievement and Drug Abuse Risk Assessed Using Instrumental Variable Analysis and Co-relative Designs
Importance: Low academic achievement (AA) in childhood and adolescence is associated with increased substance use. Empirical evidence, using longitudinal epidemiologic data, may provide support for interventions to improve AA as a means to reduce risk of drug abuse (DA). Objective: To clarify the nature of the association between adolescent AA and risk of DA by using instrumental variable and co-r
Composition and physicochemical properties of dried berry pomace
BACKGROUND: Berry pomace is a valuable but little used by-product of juice manufacturing. When processed to a stable fruit powder, the composition differs from that of the whole fruit. To facilitate application in foods, a detailed knowledge of its composition and physicochemical properties is essential. RESULTS: Blackcurrant, redcurrant, chokeberry, rowanberry and gooseberry were selected for ana
Life-changing or trivial : Electricians' views about electrical accidents
BACKGROUND: It is well known that electrical accidents can cause physical injury. Less well known is that long-term consequences may include emotional and cognitive problems. OBJECTIVE: To explore electricians' experiences and perceptions of work-related electrical accidents, with focus on psychological short- and long-term consequences, including how contacts with health care services and the wor
Regional path dependence and path creation: a conceptual way forward
Path dependence has claimed its place as a core component of economic geography, but recently the concept has been criticized for the sole focus on external shocks and lock-ins. This critique has inspired scholarly work on new path development which gives great attention to endogenous pre-conditions for new path development. However, several shortcomings still exist. The main aim of this chapter i
Alltid engelska i engelskundervisningen? : Flerspråkiga elevers perspektiv
Ska elevers olika modersmål samt skolspråket svenska användas på engelsklektioner? Detta är den övergripande frågeställningen i forskningsprojektet Flerspråkiga praktiker – en resurs i engelskundervisningen? som är finansierat av Vetenskapsrådet. I föreläsningen presenteras forskning om undervisning och lärande i engelska som ligger till grund för projektet samt projektets första resultat. Dessa b
Uncontracted basis sets for ab initio calculations of muonic atoms and molecules
In this work, we investigated muonic atoms and molecules from a quantum chemist's viewpoint by incorporating muons in the CASSCF model. With the aim of predicting muonic X-ray energies, primitive muonic basis sets were developed for a selection of elements. The basis sets were then used in CASSCF calculations of various atoms and molecules to calculate muonic excited states. We described the influ
Axial turbine design for a twin-turbine heavy-duty turbocharger concept
In the process of evaluating a parallel twin-turbine pulseturbocharged concept, the results considering the turbine operation clearly pointed towards an axial type of turbine. The radial turbine design first analyzed was seen to suffer from suboptimum values of flow coefficient, stage loading and blade-speed-ratio. Modifying the radial turbine by both assessing the influence of "trim" and inlet ti
Enhanced heat transfer and thermal performance of a blade with tree-shaped film cooling channels
Modern film cooling is an essential method to protect the turbine blade from the hot gas, and the issue about how to improve the film cooling performance has attracted much attention. In this study, a tree-shaped film cooling structure is carried out to improve the overall effectiveness and better decrease the metal temperature of the blade at the same time. To validate the superiority of the prop
Participatory parity in schooling and moves towards ordinariness : a comparison of refugee education policy and practice in England and Sweden
Within the current global refugee crisis this paper emphasises the fundamental role of education in facilitating the integration of young new arrivals. It argues that a humanitarian problem of such scale requires a commensurate humanitarian response in the form of socially-just educational policies and practices in resettlement contexts within Europe. Utilising the theoretical concepts, ‘participa
Improved lumbar infusion test analysis for normal pressure hydrocephalus diagnosis
Objectives: Constant infusion lumbar infusion test (LIT) is an important way to find which patients, of those with signs and symptoms corresponding to normal pressure hydrocephalus (NPH) who will improve from shunt operation. LIT is a stress test on the ability for cerebrospinal fluid re-absorbtion. The aim of this study is to show how the information from LIT can be improved by quantitative analy
Recycling of MSWI-bottom ash in paved constructions in Sweden – A risk assessment
This paper presents results from a risk assessment of recycling pre-treated bottom ash from municipal solid waste incineration as a subbase layer in certain asphalt paved constructions in Sweden. Based on a model for assessing environmental and health risks at contaminated areas, previously developed by the Swedish EPA and by the Swedish Geotechnical Institute, target values for total content and
