  1. 6. Antibiotics use in relation to colorectal cancer risk, survival and postoperative complications

    Författare :Sai San Moon Lu; Bethany van Guelpen; Sophia Harlid; Jonas Ludvigsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; antibiotics; gut microbiome; dysbiosis; cancer-specific survival; surgical site infections; anastomotic leakage; register-based epidemiology; Cancer Epidemiology; cancerepidemiologi; Cancer Epidemiology; cancerepidemiologi; Oncology; onkologi; Surgery; kirurgi;

    Sammanfattning : Background: Growing evidence suggests that antibiotic-induced dysbiosis of gut microbiota potentially contributes to colorectal cancer development and oncological outcomes. However, the role of antibiotics in colorectal cancer incidence, survival and postoperative outcomes at a population level remains incompletely understood. LÄS MER

  3. 7. Waves and instabilities through the lens of asymptotic analysis

    Författare :Anthony Bonfils; John Wettlaufer; Dhrubaditya Mitra; Woosok Moon; Jerome Neufeld; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; waves; wrinkles; instabilities; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Understanding the interaction of water waves with winds and marine currents is a fundamental problem in geophysical fluid dynamics. From the point of view of hydrodynamic stability, surface waves are regarded as perturbations of an inviscid parallel shear flow modeling the wind in the air and the current in the water. LÄS MER

  4. 8. Regolith Properties of Mercury Derived from Observations and Modelling

    Författare :Johan Warell; Nick Thomas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Mercury; Moon; imaging; photometry; spectroscopy; regolith; space weathering; light scattering; spectral modelling; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; astronomi; Astronomy;

    Sammanfattning : The properties of Mercury's regolith have been investigated at optical and near-infrared wavelengths with high-resolution imaging, photometric, and spectroscopic observations with the Swedish Vacuum Solar Telescope and the Nordic Optical Telescope. A new global optical map at a spatial resolution of 200 km shows that the well known (from Mariner 10) and poorly known hemispheres are indistinguishable with respect to the distribution, number density, and morphological parameters of bright albedo features.

  5. 9. The evolution of lunar breccias : U-Pb geochronology of Ca-phosphates and zircon using Secondary Ion Mass Spectrometry

    Författare :Fiona Karen Thiessen; Martin Whitehouse; Alexander Nemchin; Victoria Pease; Barbara Cohen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Moon; impact breccias; Apollo missions; impact event; Late Heavy Bombardment; zircon; Ca-phosphates; U-Pb; SIMS; geochronology; Geology; geologi;

    Sammanfattning : Planetary bodies in our Solar System, including the Moon, were exposed to an intense asteroid bombardment between ~4.5-3.8 Ga, shaping their surfaces and leaving visible “footprints” in the form of large impact basins. The end of this period (~4. LÄS MER

  7. 10. Celestial Orientation in Dim Light

    Författare :Marie Dacke; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polarisation pattern; moon; polrised light detection; twilight; dim light; dung beetle; Zoologi; spider; vision; orientation; Zoology;

    Sammanfattning : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. LÄS MER
