Multi-strange baryon production at mid-rapidity in Pb-Pb collisions at root s(NN)=2.76 TeV
The production of Xi(-) and Omega(-) baryons and their anti-particles in Pb-Pb collisions root s(NN) = 2.76 TeV has been measured using the ALICE detector. The transverse momentum spectra at mid-rapidity (vertical bar y vertical bar < 0.5) for charged Xi and Omega hyperons have been studied in the range 0.6 < P-T < 8.0 GeV/c and 1.2 < p(T) < 7.0 GeV/c, respectively, and in several centrality inter
Medier och minnen
The rapid technological developments of the new millennium have presented exciting challenges to the well-established field of cultural memory studies. Today, it behoves us analyse the ways in which digital systems make it possible to store, copy, and decentralize memories, making them increasingly accessible on the Internet. The digital media offer gateways to the past that are more comprehensive
Non-binary and linear precoded faster-than-Nyquist signaling
Faster than Nyquist (FTN) signaling is an important method of narrowband coding. The concept is extended here to non binary signal constellations; these are much more bandwidth efficient than binary ones. A powerful method of finding the minimum distance for binary and non binary FTN is presented. Precoding FTN transmissions with short linear filters proves to be an effective way to gain distance.
Prevalence and treatment of heart failure in Swedish nursing homes
Background: Since the burden of care for elderly patients with heart failure (HF) can be decreased by therapeutic measures, it is important that such patients are identified correctly. This study explores the prevalence of HF in nursing homes in Sweden, with special consideration of the risk of failure to diagnose HF in the study population. A second aim is to explore medication and the adherence
Crypt fission contributes to postnatal epithelial growth of the small intestine in pigs
Studies on growth of the small intestine have mostly concentrated on crypt hyperplasia rather than crypt fission (CF). The process of crypt bifurcation has been identified in rodents and humans but not in swine. The main aims of this study were: 1) to investigate quantitatively crypt fission in the small intestine mucosa of pigs of different age-groups and 2) to assess the effect of colostrum and

Vitamin D Receptor Polymorphisms and Breast Cancer Risk: Results from the National Cancer Institute Breast and Prostate Cancer Cohort Consortium
Background: Vitamin D is hypothesized to lower the risk of breast cancer by inhibiting cell proliferation via the nuclear vitamin D receptor (VDR). Two common single nucleotide polymorphisms (SNP) in the VDR gene (VDR), rs154441.0 (BsmI), and rs2228570 (FokI), have been inconsistently associated with breast cancer risk. Increased risk has been reported for the FokIff genotype, which encodes a less
Techno-economic evaluation of a two-step biological process for hydrogen production.
An integrated biological process for the production of hydrogen based on thermophilic and photo-heterotrophic fermentation was evaluated from a technical and economic standpoint. Besides the two fermentation steps the process also includes pretreatment of the raw material (potato steam peels) and purification of hydrogen using amine absorption. The study aimed neither at determining the absolute c
Seasonal changes in lipid composition and glycogen storage associated with freeze-tolerance of the earthworm, Dendrobaena octaedra
The earthworm, Dendrobaena octaedra, is a common species in the uppermost soil and humus layers of coniferous forests and tundra in temperate and subarctic regions. The species is freeze-tolerant and may survive several months in a frozen state. Upon freezing, glycogen reserves are rapidly converted to glucose serving as a cryoprotectant and fuel for metabolism. In the present study we investigate
Nuclear expression of STAT6 distinguishes solitary fibrous tumor from histologic mimics
Solitary fibrous tumor (SFT) is composed of spindled to ovoid cells in a patternless architecture with prominent stromal collagen and hemangiopericytoma-like vessels. Some tumors show hypercellularity, nuclear atypia, and significant mitotic activity; the latter feature in particular often portends an aggressive clinical course. SFT can sometimes be difficult to distinguish from other benign mesen
Cloud Droplet Activation of Amino Acid Aerosol Particles.
In this work we investigated the ability of a series of amino acids to act as cloud condensation nuclei using a static thermal gradient diffusion type cloud condensation nucleus counter. Particles of pure dry l-glycine, glycyl-glycine, l-serine, l-methionine, l-glutamic acid, l-aspartic acid, and l-tyrosine were studied as well as internally mixed dry particles containing ammonium sulfate and one
Genomic characterization of ETV6/RUNX1-positive acute lymphoblastic leukemia
The t(12;21) translocation generates the ETV6/RUNX1 fusion gene, present in 25% of childhood acute lymphoblastic leukemia. This fusion gene is important for leukemia development but is not sufficient for leukemia to arise. Hence, the additional genetic changes present in leukemic ETV6/RUNX1-positive cells give important clues regarding the history of the leukemia. The aim of this thesis has been t

Suspended biofilm carrier and activated sludge removal of acidic pharmaceuticals.
Removal of seven active pharmaceutical substances (ibuprofen, ketoprofen, naproxen, diclofenac, clofibric acid, mefenamic acid, and gemfibrozil) was assessed by batch experiments, with suspended biofilm carriers and activated sludge from several full-scale wastewater treatment plants. A distinct difference between nitrifying activated sludge and suspended biofilm carrier removal of several pharmac

The planet search programme at the ESO CES and HARPS IV. The search for Jupiter analogues around solar-like stars
Context. In 1992 we began a precision radial velocity survey for planets around solar-like stars with the Coude Echelle Spectrograph and the Long Camera (CES LC) at the 1.4m telescope in La Silla (Chile) resulting in the discovery of the planet iota Hor b. We have continued the survey with the upgraded CES Very Long Camera (VLC) and the HARPS spectrographs, both at the 3.6m telescope, until 2007.
Methods used in clinical development of novel anti-asthma therapies
In recent years, it has become increasingly important to get as much as possible information on clinical efficacy already in the early phases of drug development. For proof of concept (POC) studies testing novel anti-inflammatory drugs in asthma, there are several validated exacerbation models, inducing various aspects of the airway inflammation and airway responsiveness. The choice of the appropr
Conceptualizing entrepreneurial capital in the context of institutional change
This paper explores the building of entrepreneurial capital from an entrepreneurship and contextual/institutional position. In taking this position, it is possible to understand "entrepreneurial capital" as the content of the process that unfolds when individuals are exposed to certain characteristics of the environment. Drawing on findings from an ethnographically inspired longitudinal case study

Pachnobium dreuxi, n. g., n. sp. discovered as a fossil and still living in the Crozet Islands (Coleoptera: Curculionidae: Ectemnorrhininae). Pachnobium dreuxi, a new genus and species of Ectemnorrhininae weevil, was first discovered as a fossil in a Holocene sedimentary sequence at lie de la Possession (Crozet Islands, southern Indian Ocean). Two modern specimens were subsequently found in the co
