  1. 1. Type Ia Supernovae : Homogeneity and Diversity

    Författare :Gabriele Garavini; Ariel Goobar; David Branch; Stockholms universitet; []
    Nyckelord :Physics;

    Sammanfattning : The use of type Ia supernovae as distance estimators has shown that about 75% of the energy content of the universe has a negative equation of state parameter and thus, drives the acceleration of the universe. Constraining the exact nature of this energy is one of the main goals in cosmology. LÄS MER

  3. 2. SEA CHANGE : Social-ecological co-evolution in Baltic Sea fisheries

    Författare :Jonas Hentati-Sundberg; Henrik Österblom; Joakim Hjelm; Trevor Branch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resilience; social-ecological systems; complex adaptive systems; fisheries; Baltic Sea; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

  4. 3. On Bundle Branch Block and Acute Myocardial Infarction

    Författare :Gunnar Thor Gunnarsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute myocardial infarction; left bundle branch block; right bundle branch block; diagnosis; prognosis; continuous vectorcardiography;

    Sammanfattning : Studies from the pre-thrombolytic era showed that patients with bundle branch block suffering acute myocardial infarction had worse prognosis compared to patients without bundle branch block. It seems that this difference still exists in the thrombolytic era, at least for short-term mortality. LÄS MER

  5. 4. On the cell cycle of Escherichia coli and cell division in Haloferax mediterranei

    Författare :Björn Gullbrand; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Branch; division; Escherichia coli; Haloferax mediterranei; replication; segregation; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : Escherichia coli has served as a model organism for prokaryotes for several decades and is perhaps the most well characterised organism on earth. The use of fluorescence microscopy during recent years has contributed substantially to our understanding of the essential cell cycle processes chromosome replication, chromosome segregation and cell division.
