PIXE in 1980: Summary of the Second International Conference on Particle Induced X-Ray Emission and its Analytical Applications

The Second International Conference on Particle Induced X-ray Emission (PIXE) and its analytical applications was held in Lund, Sweden, June 9-12, 1980. About a hundred papers were presented, including seven invited talks (PIXE and particle scattering, microbeam analysis (2), applications to aerosols (2) and biological samples (2)). The main impression left by the conference was that both the PIXE

Tree-ring stable carbon isotope-based May-July temperature reconstruction over Nanwutai, China, for the past century and its record of 20th century warming

Growth anomaly of trees in some regions was detected under current episode of rapid warming. Thisraises a dilemma for temperature reconstructions by using tree-ring width which is believed to be themost important proxy on inter-annual temperature reconstruction during the past millenniums. Here weemployed the tree-ring d13C to reconstruct temperature variations for exploring their potential oncapt

Evaluation of Human Papillomavirus Antibodies and Risk of Subsequent Head and Neck Cancer.

PURPOSEHuman papillomavirus type 16 (HPV16) infection is causing an increasing number of oropharyngeal cancers in the United States and Europe. The aim of our study was to investigate whether HPV antibodies are associated with head and neck cancer risk when measured in prediagnostic sera. METHODSWe identified 638 participants with incident head and neck cancers (patients; 180 oral cancers, 135 oro

Spectroscopic Atlas of Atmoshperic Microwindows in the Middle Infra-Red

This second edition of the infrared microwindow atlas contains a collection of spectral mi- crowindows commonly used or recently suggested for ground-based, high resolution, infrared solar absoption spectroscopy. These solar observations are aimed at quantifying the abun- dance of trace species in the terrestrial atmosphere. A microwindow is a narrow spectral interval that allows to observe a spec

Primary Disseminated Multifocal Ewing Sarcoma: Results of the Euro-EWING 99 Trial.

PURPOSE To improve the poor prognosis of patients with primary disseminated multifocal Ewing sarcomas (PDMES) with a dose-intense treatment concept. PATIENTS AND METHODS From 1999 to 2005, 281 patients with PDMES were enrolled onto the Euro-EWING 99 R3 study. Median age was 16.2 years (range, 0.4 to 49 years). Recommended treatment consisted of six cycles of vincristine, ifosfamide, doxorubicin, a

Molecular evolution of a C5aR antagonist against inflammatory disease

New anti-inflammatory drugs with fewer adverse effects than existing drugs may prove to be useful in the treatment of several inflammatory disorders. A critical step in acute inflammation is the infiltration of neutrophils into tissues. Therefore, molecules that target and inhibit this early inflammatory event are attractive to engineer to suit medical needs. The Chemotaxis Inhibitory Protein of

In vivo inhibition of transcellular water channels (Aquaporin-1) during acute peritoneal dialysis in rats

During peritoneal dialysis (PD), a major portion of the osmotically induced water transport to the peritoneum can be predicted to occur through endothelial water-selective channels. Aquaporin-1 (AQP-1) has recently been recognized as the molecular correlate to such channels. Aquaporins can be inhibited by mercurials. In the present study, HgCl2 was applied locally to the peritoneal cavity in rats

Culturally queer, silenced in school? Children with LGBTQ parents, and the everyday politics of/in community and school

Children with lesbian, gay, bisexual, trans* and/or queer (LGBTQ) parents have received heightened attention during the processes of policy making regarding adoption and donor insemination legislation in Sweden during the 1990s and early 2000s. Yet, very little academic knowledge exists about children and young people in LGBTQ families and their experiences in schools. We engage the idea of "cultu

Gene-centric meta-analyses for central adiposity traits in up to 57 412 individuals of European descent confirm known loci and reveal several novel associations

Waist circumference (WC) and waist-to-hip ratio (WHR) are surrogate measures of central adiposity that are associated with adverse cardiovascular events, type 2 diabetes and cancer independent of body mass index (BMI). WC and WHR are highly heritable with multiple susceptibility loci identified to date. We assessed the association between SNPs and BMI-adjusted WC and WHR and unadjusted WC in up to

Heavy Meromyosin Molecules Extending More Than 50 nm above Adsorbing Electronegative Surfaces

In the in vitro motility assay, actin filaments are propelled by surface-adsorbed myosin motors, or rather, myosin motor fragments such as heavy meromyosin (HMM). Recently, efforts have been made to develop actomyosin powered nanodevices on the basis of this assay but such developments are hampered by limited understanding of the HMM adsorption geometry. Therefore, we here investigate the HMM adso

Detecting changes in vegetation trends using time series segmentation

Although satellite-based sensors have made vegetation data series available for several decades, the detection of vegetation trend and change is not yet straightforward. This is partly due to the scarcity of available change detection algorithms suitable for identifying and characterizing both abrupt and non-abrupt changes, without sacrificing accuracy or computational speed. We propose a user-fri

A SUMOylation-defective MITF germline mutation predisposes to melanoma and renal carcinoma

So far, no common environmental and/or phenotypic factor has been associated with melanoma and renal cell carcinoma (RCC). The known risk factors for melanoma include sun exposure, pigmentation and nevus phenotypes(1); risk factors associated with RCC include smoking, obesity and hypertension(2). A recent study of coexisting melanoma and RCC in the same patients supports a genetic predisposition u

Bly i jord och växter: Tillväxt och blyupptag

Jord i anslutning till skjutbanor innehåller ofta mycket höga blyhalter. Blyföroreningarna medför ett ökat upptag av bly i de växter som växer i jord från skjutbanor. Matväxter från skjutbanor kan kraftigt överskrida gränsvärdena för bly i livsmedel. För växterna medför blyexponeringen en omfördelning av biomassa, från rötter till skott. Bly är en tungmetall, och är giftig för såväl växter som djThis study investigates how lead content and bioavailability in soil affects growth and root/shoot ratio in three commonly cultivated species: wheat (Triticum turgidum), clover (Trifolium) and radish (Raphanus sativus). The study investigates the levels at which soil lead content contribute to toxic effects in plants, and when it may pose a risk to consumers. In addition, lead accumulation and the

Online Interactions

Communication today is not something merely taking place face to face, technology such as the internet and social media channels have opened up for endless interactions taking place in the online world. User generated content in the form of online travel reviews come with many challenges and opportunities for organizations. User generated content has been shown to impact a travelers decision in al

Shedding Light Upon Logistics Manager Everyday Work Practices - A Practice Theory Perspective

Purpose: The purpose of this research is to contribute to logistics research arena in management practices using qualitative methods. Because previous research paradigm has been dominated by quantitative methods, where managerial work practices have been neglected or understated. Hence, by using the qualitative method the study can enrich the importance of manager work practice in logistics and br

Modern arkitektur i kulturhistorisk miljö

The thesis uses hermeneutical analysis as well as reception and content analysis to interpret a current architectural debate. Within the architectural profession, there is a dogmatic style standard. Since the 1930s, modernism (also known as functionalism) has been the predominating style in architecture. This has led to an open resistance to architectural modernism brought before the public and to
