Interactions between Predation and Resources Shape Zooplankton Population Dynamics.

Identifying the relative importance of predation and resources in population dynamics has a long tradition in ecology, while interactions between them have been studied less intensively. In order to disentangle the effects of predation by juvenile fish, algal resource availability and their interactive effects on zooplankton population dynamics, we conducted an enclosure experiment where zooplankt

Follow-up of Adolescents Born Extremely Preterm Cognitive Function and Health at 18 Years of Age.

Abstract Aim: To compare cognitive ability, school achievement and self-perceived health aspects in adolescents born extremely preterm and term born controls. Method: Fifty-two, out of 61, extremely preterm born adolescents (mean age 18.4 years) and 54 matched controls (mean age 18.3 years) born at full term were investigated; intelligence quotient was measured with the Wechsler Adult Intelligence

Abstract in Romanian I denna artikel gör vi en jämförelse, i historiskt perspektiv, vad gäller rumänska studier på campus och via internet. Vi diskuterar en mycket intressant fråga i detta moderna lärandesystem, i.e ”e-learning”, nämligen lärarens nya roll.

Iso-luminance counterillumination drove bioluminescent shark radiation.

Counterilluminating animals use ventral photogenic organs (photophores) to mimic the residual downwelling light and cloak their silhouette from upward-looking predators. To cope with variable conditions of pelagic light environments they typically adjust their luminescence intensity. Here, we found evidence that bioluminescent sharks instead emit a constant light output and move up and down in the

Belonia nidarosiensis funnen i Sverige

Redan för några år sedan hittade Mikael Hagström och Jan Henriksson B. nidarosiensis på Gotland, men av flera anledningar har det tagit lite tid att få klarhet vad det var för art. Nedan beskriver de tillsammans med Ulf Arup hela historien om fynden på Gotland.

Effect of Probiotic Bacteria on Microbial Host Defense, Growth, and Immune Function in Human Immunodeficiency Virus Type-1 Infection

The hypothesis that probiotic administration protects the gut surface and could delay progression of Human Immunodeficiency Virus type1 (HIV-1) infection to the Acquired Immunodeficiency Syndrome (AIDS) was proposed in 1995. Over the last five years, new studies have clarified the significance of HIV-1 infection of the gut associated lymphoid tissue (GALT) for subsequent alterations in the microfl

New tool for promotion of energy management and cleaner production on no cure, no pay basis

Even enterprises with very advanced management systems seldom monitor efficiency of energy usage and materials flows within their processes and have, therefore, difficulty to effectively manage their resource efficiency. This paper is built upon experiences from a pilot implementation of a new tool for promotion of energy management and cleaner production, developed within the Energy Management an

Prediction of stopping-power ratios in flattening-filter free beams.

PURPOSE: In recent years, there has been an increasing interest in flattening-filter free (FFF) beams. However, since the removal of the flattening filter will affect both the mean and the variance of the energy spectrum, current beam-quality specifiers may not be adequate for reference dosimetry in such beams. The purpose of this work was to investigate an alternative, more general beam-quality s

Real-world cost-effectiveness in chronic myeloid leukemia: the price of success during four decades of development from non-targeted treatment to imatinib

Imatinib has revolutionized the treatment of chronic myeloid leukemia (CML). We evaluated clinical outcome and cost-effectiveness, using Swedish registry data based on patients with CML diagnosed 1973-2008. Outcome from three time periods (I: 1973-1979; II: 1991-1997; III: 2002-2008) associated with symptomatic treatment, interferon-alpha/stem cell transplant and implementation of imatinib, respec

Detailed measurement of the e(+)e(-) pair continuum in p plus p and Au plus Au collisions at root s(NN)=200 GeV and implications for direct photon production

PHENIX has measured the e(+)e(-) pair continuum in root s(NN) = 200 GeV Au+Au and p+p collisions over a wide range of mass and transverse momenta. The e(+)e(-) yield is compared to the expectations from hadronic sources, based on PHENIX measurements. In the intermediate-mass region, between the masses of the phi and the J/psi meson, the yield is consistent with expectations from correlated c (c) o

On the Inverse Problem for Quantum Graphs with One Cycle

Quantum graphs having one cycle are considered. It is shown that if the cycle contains at least three vertices. then the potential oil the graph can be uniquely reconstructed from the corresponding Titchmarsh-Weyl function (Dirichlet-to-Neumann map) associated with graph's boundary, provided certain non-resonant conditions are satisfied

Moving towards an ecologically sound society? Starting from green universities and environmental higher education

Moving towards an ecologically sound society requires strong support from higher educational institutions. During the past decade, the Journal of Cleaner Production has published more than 150 articles that have highlighted advances in academic efforts on sustainability in higher education, that were focused upon education, research, outreach and greening of campus operations in universities from

Cardiac arrest and therapeutic hypothermia: Prognosis and outcome

Popular Abstract in Swedish Personer som drabbas av hjärtstopp riskerar grava hjärnskador p.g.a. brist på blodflöde till hjärnan. Patienterna blir ofta långvarigt medvetslösa och vårdas på intensiv¬vårdsavdelning i respirator. Risken för hjärnskada kan minskas med kyl¬behandling. Under kylbehandlingen, cirka 1.5 dygn, får patienten sederande och ev. muskelavslappnande medicin för att minska ”huttrAbstract Therapeutic hypothermia (TH) is the only treatment available to reduce neurological sequels for unconscious patients following cardiac arrest (CA). TH requires sedation and muscular relaxation, obscuring the clinical neurological examination for estimation of prognosis, and clinical decision making. Continuous amplitude-integrated EEG (aEEG) has been used to predict outcome in neonates
