<p>Abstract</p> <p>Background</p> <p>The sea urchin embryo has been an important model organism in developmental biology for more than a century. This is due to its relatively simple construction, translucent appearance, and the possibility to follow the fate of individual cells as development to the pluteus larva proceeds. Because the larvae contain tiny calcitic skeletal elements, the spicules, they are also important model organisms for biomineralization research. Similar to other biominerals...

We combined large eddy simulation (LES) with a thermodynamic slab ice model to simulate and study the sea ice motion and frazil ice dynamics in the ocean mixed layer in the Arctic winter. To show the accurate representation of leads in models, fluxes distributed laterally beneath leads and sea ice need to be parameterized. The 3-D LES model, which is developed from a 2-D turbulence model, is used to model the convection of beneath leads and sea ice. The experiments were then ac...

Introduction: Radiographer´s usual role in the medical imaging chain is to acquire relevant and qualitatively good images that help the radiologist or physician to diagnose most accurately. After the image acquisition, the radiographer does a quality evaluation based on established imaging criteria to decide if the image is satisfactory, or otherwise reject it and subsequently take a new one. Contrary to expectations that the number of image rejects should decrease substantially with the introdu...

<p>Abstract</p> <p>Background</p> <p>The main cause of relapse in smokers attempting to quit is inability to resist urges to smoke. Pharmacotherapy ameliorates but does not entirely prevent urges to smoke when abstinent, so other methods to resist urges to smoke might be helpful. Exercise is effective, but aerobic exercise is often impractical when urges strike. Two techniques, body scan and isometric exercise, have been shown to reduce urge intensity and nicotine withdrawal symptoms in temporar...

A Sinemurian mudstone-dominated succession was exposed until recently in the Gantofta quarry in Skåne, southern Sweden. The deposits are placed in the Döshult and Pankarp Members of the Sinemurian–Aalenian Rya Formation. Similar facies of the same age are widespread in the Danish Basin where they constitute the F-Ib unit (F-I member) of the Fjerritslev Formation. The Gantofta succession thus represents the easternmost extension of the environment characteristic of the Fjerritslev Formation and i...

<p>Abstract</p> <p>Despite substantial progress, there are still several gaps in our knowledge about the process of sex chromosome differentiation. The degeneration of sex-specific chromosome in some species is well documented, but it is not clear if all species follow the same evolutionary pathway. The accumulation of repetitive DNA sequences, however, is a common feature. To better understand this involvement, fish species emerge as excellent models because they exhibit a wide variety of sex c...

Ivo Andrić is probably the most important Yugoslav author. His international reputation is constructed and then consolidated with the Nobel Prize in literature in 1961. Exactly this reputation was the reason for a one-sided reading of his works – especially the novel Bridge over Drina – by some Bosnian Muslim intellectuals, notably Šefkija Kurtović who criticized Andrić for his allegedly biased representation of Bosnia and its Muslim inhabitants. This critic was possible only in emigrant circles...

During the Holocene relative uplift of land in Finland coastal dunes were formed at various altitudes in areas earlier submerged. Some ventifacts found near these dunes, the oldest being about 4000 years old, are described from the Hanko (Hangö) peninsula and from Kalajoki in Ostrobothnia. The hard rock ventifacts have a shiny upper surface with no facets developed.

Abstract Background Fishing activities can influence foraging behaviour of many seabird species worldwide. Seabirds are attracted by fishing vessels which can facilitate access to demersal fish as a novel food resource that otherwise would be unavailable. On the other hand, intense fishing activities cause depletion of fish stocks with a reduction of natural prey available for seabirds. Moreover, fisheries discards can have lower nutritional value than natural prey. However, the importance of fi...
