Herbivore teeth predict climatic limits in Kenyan ecosystems

A major focus in evolutionary biology is to understand how the evolution of organisms relates to changes in their physical environment. In the terrestrial realm, the interrelationships among climate, vegetation, and herbivores lie at the heart of this question. Here we introduce and test a scoring scheme for functional traits present on theworn surfaces of large mammalian herbivore teeth to captur

Labouring to Learn : Union Renewal in Swedish Manufacturing

As a response to post-Fordist production conditions, Swedish manufacturing unions have sought to develop their respective agendas beyond the traditional focus on distribution issues. A new emphasis on competence at the workplace suggests an increasing need for unions to develop a capacity to learn as organisations. The thesis accordingly sets out to further our theoretical knowledge of change in t

Methodology and Applications of Visual Stance Analysis : An Interactive Demo

Analysis of stance in textual data can reveal the attitudes of speakers, ranging from general agreement/disagreement with other speakers to fine-grained indications of wishes and emotions. The implementation of an automatic stance classifier and corresponding visualization techniques facilitates the analysis of human communication and social media texts. Furthermore, scholars in Digital Humanities

Polymorphisms in ATP-binding cassette transporters associated with maternal methylmercury disposition and infant neurodevelopment in mother-infant pairs in the Seychelles Child Development Study

Background: ATP-binding cassette (ABC) transporters have been associated with methylmercury (MeHg) toxicity in experimental animal models. Aims: To evaluate the association of single nucleotide polymorphisms (SNPs) in maternal ABC transporter genes with 1) maternal hair MeHg concentrations during pregnancy and 2) child neurodevelopmental outcomes. Materials and methods: Nutrition Cohort 2 (NC2) is

Brev som liv och konst. Brevväxlingen mellan Lilli Jahn och hennes barn

The letters between the jewish Lilli Jahn and her four young children during 1943 and 1944 are analyzed as representation of reality, i e the terrible situation and fate of Lilli Jahn (murdered in Auschwitz) and the children, and as art, the conscious forming of the letters of Jahn, adhering to the norms of the familiar letter.

Denitrification and DNRA at the Baltic Sea oxic–anoxic interface : Substrate spectrum and kinetics

The dependence of denitrification and dissimilatory nitrate reduction to ammonium (DNRA) on different electron donors was tested in the nitrate-containing layer immediately below the oxic–anoxic interface (OAI) at three stations in the central anoxic basins of the Baltic Sea. Additionally, pathways and rates of fixed nitrogen transformation were investigated with 15N incubation techniques without

Emotional kinship care and neutral non-kinship care - the struggle between discourses

In this paper, social workers' ideas of kinship care and non-kinship care as foster placement alternatives for vulnerable children are analysed and discussed. The study is based on group interviews with Swedish social workers, using a discourse analytic approach. The interviews took two vignettes of children who needed an immediate and long-term placement because one of the parents had killed the

Throat related symptoms and voice : development of an instrument for self assessment of throat-problems

BACKGROUND: Symptoms from throat (sensation of globus; frequent throat clearing; irritated throat) are common in patients referred to voice clinics and to ENT specialists. The relation to symptoms of voice discomfort is unclear and in some cases patients do not have voice problems at all. Instruments for patients' self-reporting of symptoms, and assessment of handicap, such as the Voice Handicap I

A FISH-based method for assessment of HER-2 amplification status in breast cancer circulating tumor cells following CellSearch isolation

Amplification of the HER-2/neu (HER-2) proto-oncogene occurs in 10%–15% of primary breast cancer, leading to an activated HER-2 receptor, augmenting growth of cancer cells. Tumor classification is determined in primary tumor tissue and metastatic biopsies. However, malignant cells tend to alter their phenotype during disease progression. Circulating tumor cell (CTC) analysis may serve as an altern

High expression of stromal PDGFRβ is associated with reduced benefit of tamoxifen in breast cancer

Cancer-associated fibroblasts (CAFs) regulate tumour growth, metastasis and response to treatment. Recent studies indicate the existence of functionally distinct CAF subsets. Suggested mechanisms whereby CAFs can impact on treatment response include paracrine signaling affecting cancer cell drug sensitivity and effects on tumour drug uptake. PDGFRβ is an important regulator of fibroblasts. Experim

Differences in endophyte communities of introduced trees depend on the phylogenetic relatedness of the receiving forest

Plant species sometimes perform extraordinarily well when introduced to new environments, through achieving higher growth rates, individual biomasses or higher densities in their receiving communities compared to their native range communities. One hypothesis proposed to explain enhanced performance in species’ new environments is that their soil microbial communities may be different and provide

A COMPARISON of STELLAR ELEMENTAL ABUNDANCE TECHNIQUES and MEASUREMENTS

Stellar elemental abundances are important for understanding the fundamental properties of a star or stellar group, such as age and evolutionary history, as well as the composition of an orbiting planet. However, as abundance measurement techniques have progressed, there has been little standardization between individual methods and their comparisons. As a result, different stellar abundance proce

Roadmap on ultrafast optics

The year 2015 marked the 25th anniversary of modern ultrafast optics, since the demonstration of the first Kerr lens modelocked Ti:sapphire laser in 1990 (Spence et al 1990 Conf. on Lasers and Electro-Optics, CLEO, pp 619-20) heralded an explosion of scientific and engineering innovation. The impact of this disruptive technology extended well beyond the previous discipline boundaries of lasers, re
