Length of activity season drives geographic variation in body size in a widely distributed lizard

Understanding the factors that drive geographic variation in life history is an important challenge in evolutionary ecology. Here, we analyze what predicts geographic variation in life-history traits of the common lizard, Zootoca vivipara, which has the globally largest distribution range of all terrestrial reptile species. Variation in body size was predicted by differences in the length of activ

Differences in recruitment and life-history strategy alter zooplankton spring dynamics under climate-change conditions.

In recent decades temperature elevation has been the focus of many studies on climate change, including effects on planktonic communities, but few studies have examined the effects of increased water color ("brownification"). Since these changes are likely to occur simultaneously, it is important to investigate their potential interactive effects. Accordingly, we performed a mesocosm experiment wh

Influence of Salt on the Self-Assembly of Two Model Amyloid Heptapeptides

We study the effects of NaCl on the self-assembly of AAKLVFF and beta A beta AKLVFF in solution. Both AAKLVFF and beta A beta AKLVFF self-assemble into twisted fibers in aqueous solution. The addition of NaCl to aqueous solutions of AAKLVFF produces large crystal-like nanotapes which eventually precipitate. In contrast, highly twisted fibrils were observed for beta A beta AKLVFF solutions at low s

Muslimska kvinnor i Israel : religionens roll i vardagslivets förflyttningar

This dissertation aims to contribute empirically and theoretically, to the field of Islamology and Religious Studies in general. It does so by investigating the possible relation between Israeli Muslim women’s choice of religious identification and their individual experiences in everyday life transitions. Many of these women are traveling daily from their hometowns or villages to the major cities

Mobility Management campaigns as part of the transition towards changing social norms on sustainable travel behaviour

In the transition towards a low-carbon society, changes of attitudes and social norms are needed to support new ways of implementing technical solutions and new behaviors and lifestyles. Mobility Management (MM) campaigns have been shown to contribute to changing of mind sets, but to date these campaigns have not been recognized as important parts of a strategic transport policy plan on an overall

Combined chemotherapy and immunotherapy against experimental malignant brain tumors

Popular Abstract in Swedish Trots ett sunt leverne med regelbunden motion och nyttig mat kan vi inte alltid förhindra risken att drabbas av vissa typer av cancer som till exempel hjärntumörer. Den vanligaste formen av elakartade hjärntumörer heter glioblastoma multiforme och är också den mest aggressiva. Symptomen varierar beroende på tumörens storlek och var i hjärnan den växer, och patienter kanGlioblastoma multiforme (GBM) is the most common and aggressive primary malignant brain tumor in adults. Despite standard treatment including surgery, radiotherapy and temozolomide (TMZ)-based chemotherapy, the prognosis for GBM patients is dismal, and there is a need for novel treatments. One possible therapeutic treatment modality presented here is immunotherapy, either alone or combined with in

Amorphous silica mobilization by inter-rill erosion: insights from rainfall experiments

Amorphous silica (ASi) carried in suspension by rivers is an important component in the global Si budget. Water erosion processes in cultivated catchments are likely to drive ASi delivery to the river system. However, no studies have investigated the controls on ASi mobilization by erosional processes in croplands. Rainfall experiments were performed on split fields (i.e. a part conventionally plo

Gravitational Scattering in the ADD-model at High and Low Energies.

Gravitational scattering in the ADD-model is considered at both sub- and transplanckian energies using a common formalism. By keeping a physical cut-off in the KK tower associated with virtual KK exchange, such as the cut-off implied from a finite brane width, troublesome divergences are removed from the calculations in both energy ranges. The scattering behavior depends on three different energy

The anticorruption package

This paper discusses the various metaphors used to describe the emerging global anticorruption regime, metaphors such as anticorruption industry, landscape, assemblage, package, gift. It is argued that anticorruptionism now has a life of its own, separate from the ostensible project of 'fighting corruption' We need to study the anticorruption 'package' as it is transmitted or donated around the wo

Director orientations in lyotropic liquid crystals: diffusion MRI mapping of the Saupe order tensor.

The macroscopic physical properties of a liquid crystalline material depend on both the properties of the individual crystallites and the details of their spatial arrangement. We propose a diffusion MRI method to estimate the director orientations of a lyotropic liquid crystal as a spatially resolved field of Saupe order tensors. The method relies on varying the shape of the diffusion-encoding ten

Design of Reconfigurable Hardware Architectures for Real-time Applications

This thesis discusses modeling and implementation of reconfigurable hardware architectures for real-time applications. The target application in this work is digital holographic imaging, where visible images are to be reconstructed based on holographic recordings. The reconstruction process is computationally demanding and requires hardware acceleration to achieve real-time performance. Thus, this

Helicobacter pylori infection assessed by ELISA and by immunoblot and noncardia gastric cancer risk in a prospective study: the Eurgast-EPIC project

In epidemiological studies, Helicobacter pylori infection is usually detected by enzyme-linked immunosorbent assay (ELISA). However, infection can spontaneously clear from the mucosa during the progression of atrophy and could lead to substantial under-detection of infection and underestimation of its effect on gastric cancer (GC) risk. Antibodies detected by western blot are known to persist long

Phototoxicity of pyrene affects benthic algae and bacteria from the arctic

Phototoxicity of polycyclic aromatic hydrocarbons (PAHs) in the Arctic is important to study since the future PAH load is likely to increase. In combination with the increased UV-Iight penetration due to ozone layer thinning, phototoxicity may be a potential problem for arctic areas. The aim of this study was to evaluate effects of pyrene and phototoxicity of pyrene on natural algae and bacteria f

Reaching the Top? On Gender Balance in the Economics Profession

Despite an increasing number of women entering the economics profession during recent decades, it is still dominated by men. This paper summarizes the situation in academic economics in Australia, Canada, Great Britain, the United States, and Sweden (substantial appendices detail the situation in Sweden, not previously been available in English). Women constitute about a third of the PhD graduates
