Flight directions and routes of migrating birds are determined by the birds' compass orientation, but also by effects of wind, social influence, responses to topography and landmarks, and to navigation cues. We investigated the orientation and routes taken by arctic shorebirds during autumn migration in southern Sweden at three different sites situated within a distance of 200 km from each other,

This paper provides three short proofs of the classical Gibbard–Satterthwaite theorem. The theorem is first proved in the case with only two voters. The general case follows then from an induction argument over the number of voters. The proof of the theorem is further simplified when the voting rule is neutral. The simple arguments in the proofs may be especially useful in classroom situations.

Wilms Tumor suppressor protein (WT1) is a transcription factor that is involved in a variety of developmental functions during organ development. It is also implicated in the pathology of several different cancer forms. The protein contains four C(2)H(2)-type zinc fingers and it specifically binds GC-rich sequences in the promoter regions of its target genes, which are either up or down regulated.

A novel design approach to form macroporous gels is presented. Macroporous gels (MGs), known as cryogels(or gels prepared at subzero temperatures), were prepared inside a protective plastic core (so-called, housing), thus making them resistant to shear forces at stirring. MGs are highly elastic polymeric materials with pore sizes up to 100 mu m and spongelike morphology. Design of MGs inside a pro

The fossil polyclinic family Polychaeturidae is considered as monogeneric and comprises four species of the genus Pteropelta. Pteropelta, originally established on isolated scolecodonts (the carriers), is revised and the apparatus-based Polychaetura is shown to be a junior synonym of Pteropelta. In addition to Pteropelta gladiata and Pteropelta kielanae. Pteropelta huberti sp. nov., and Pteropelta

We report the observation of anomalous bands in graphite valence band structure in angle-resolved photoemission spectroscopy (ARPES) experiments. The photon energy dependence of these bands shows a constant kinetic energy nature. Our results are supported by the very low energy electron diffraction data reported on graphite surfaces which essentially map the unoccupied states representing the phot

Popular Abstract in Swedish Vi är omringade av olika mikrorganismer såsom bakterier och svampar. Bakterier kan leva från de mest ogästvänliga miljöer som arktisk is och varma källor på havsbotten till varje människas hud och mag- tarmkanal. Bakterier som bor på och inuti oss spelar en stor roll i vårt välbefinnande. De hjälper oss att smälta maten och hindrar andra mer farliga bakterier från att bAssociation to specific host tissue structures allows pathogenic bacteria to establish an infection and facilitates the spread within its host. Interactions between bacterial surface structures and human proteins might determine the outcome of the infection. Streptococcus pyogenes (S. pyogenes), is a human pathogen mostly causing localized infections of the skin and respiratory tract, but it is al

Background Patients with chromosome 5 abnormalities and high-risk myelodysplastic syndromes or acute myeloid leukemia have a poor outcome. We hypothesized that increasing doses of lenalidomide may benefit this group of patients by inhibiting the tumor clone, as assessed by fluorescence in situ hybridization for del(5q31). Design and Methods Twenty-eight patients at diagnosis or with relapsed disea

A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming a significant branching ratio for subsequent decay into a W boson and a b quark. The search is based on 4.7 fb(-1) of pp collisions root s = 7 TeV recorded in 2011 with the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, characterized by

The electronic structure of the strongly Coulomb correlated cuprate CuGeO3 has been calculated by the local-density-approximation method (LDA+U). The parameter U was varied from 0 to 8 eV. The results of the band-structure calculations are compared with experimental data obtained by means of X-ray photoelectron and resonant X-ray emission spectroscopy methods (Cu Lalpha and O Kalpha X-ray emission

In rats the flow of urine was diverted from the bladder over a period of 7-10 days. Active length-tension curves of muscle strips of such disused bladders did not differ from those of controls, provided lengths were related to optimum length for force development. When, however, lengths were related to length in situ the active length-tension curves were shifted to the left. The muscle strips of t

Implicit figuration and subjective interpretation make up the conventional basis of the classical discussion of the omprehensiveness and aesthetic quality of the metaphor.Its function and use in Social Science is illustrated as a background to a radical different methodological approach. By means of Perspective Text Analysis it is demonstrated that the metaphor has to be conceived as the Re-naming

A DNA variation in the coding region of the human cystatin C gene has been detected by direct sequencing. The polymorphism, a G/A transition, leads to an Ala/Thr variation in the penultimate amino acid of the signal peptide. The base substitution results in the loss of a SstII restriction site, thus allowing the design of a rapid polymerase chain reaction assay for analysis of this polymorphism in

A chronology based on optically stimulated luminescence (OSL) dating is presented for the late- and post-glacial evolution of the southern Baltic Sea (-15ka to present). During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. Previous attempts to establish a chronology for these palaeoenvironmental cha
