Search for the Standard Model Higgs boson in the H -> WW(*()) -> lvlv decay mode with 4.7 fb(-1) of ATLAS data at root s=7 TeV

A search for the Standard Model Higgs boson in the H -> WW(*()) -> lvlv (l = e.mu) decay mode is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 4.7 fb(-1) at a centre-of-mass energy of 7 TeV collected during 2011 with the ATLAS detector at the Large Hadron Collider. No significant excess of events over the expected background is o

Soil surface CO2 efflux measurements in Norway spruce forests: Comparison between four different sites across Europe - from boreal to alpine forest

Extensive measurements of soil surface (including vegetation cover) CO2 efflux were carried out on 80 positions at four different forest sites (Sweden, Germany, Czech Republic and Italy) using a closed dynamic chamber technique. The period of measurement was 4-5 consecutive days per site. Two approaches were used to analyze the measured data, the Q(10) parameter and the Arrhenius relationship. Bas

Functionalised ZnO-nanorod-based selective electrochemical sensor for intracellular glucose

In this article, we report a functionalised ZnO-nanorod-based selective electrochemical sensor for intracellular glucose. To adjust the sensor for intracellular glucose measurements, we grew hexagonal ZnO nanorods on the tip of a silver-covered borosilicate glass capillary (0.7 mu m diameter) and coated them with the enzyme glucose oxidase. The enzyme-coated ZnO nanorods exhibited a glucose-depend

Yrkeskunnande och kompetensutveckling i arbetet med vuxna individer med utvecklingsstörning – ett vårdarperspektiv

Since the law of support and service for people with certain disabilities (LSS) was implemented 1994, the carers’ role has changed from «taking care of» to «giving support to» people with intellectual disabilities/autism, but the requirements of knowledge hasn’t been altered. In order to provide appropriate support, carers need both theoretical knowledge and experience of how people with intellect

A critical literature review of moisture and temperature conditions in wood exposed outdoors above ground

Summary In the majority of the field studies reviewed in this report samples were exposed outdoors above ground and only the average moisture content was determined. Therefore, no information is given about the moisture content in joints and other moisture traps. In many of the field studies, information on relative humidity, temperature, rainfalls etc. is missing and consequently these field stud

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

Indirect, non-competitive amperometric immunoassay for accurate quantification of calpastatin, a meat tenderness marker, in bovine muscle

A method is described for quantification of the beef tenderness marker, calpastatin, in meat samples by amperometric detection. Using a novel bovine recombinant partial calpastatin protein as standard antigen a low detection limit of 0.2 ng/mL was achieved. The influence of the complex matrix was minimised by heat pretreatment and dilution of the samples prior to detection of calpastatin. The rela

Charge state readout and hyperfine interaction in a few-electron InGaAs double quantum dot

A laterally defined InGaAs double quantum dot with an integrated charge readout sensor is realized in an InGaAs/InP heterostructure. The charge states of the double quantum dot are measured with the use of the charge readout sensor in the few-electron regime in which the current is too weak to be observable by direct measurements of electron transport through the double dot. We also measure the le

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

Coastal cliffs on islands as foraging habitat for bats

Small islands usually show simplified ecosystems with limited availability of suitable foraging habitats for bats, thus habitat selection on islands may differ compared to the mainland. Habitats that are marginal on the mainland may be important on islands. The island of Capri consists, to a large extent, of steep limestone cliffs and Mediterranean shrubland, with virtually no forests or other hab

Genetic Polymorphisms in Host Innate Immune Sensor Genes and the Risk of Nasopharyngeal Carcinoma in North Africa

Nasopharyngeal carcinoma (NPC) is a rare malignancy in most parts of the world. It is an Epstein-Barr virus-associated malignancy with an unusual racial and geographical distribution. The host innate immune sensor genes play an important role in infection recognition and immune response against viruses. Therefore, we examined the association between polymorphisms in genes within a group of pattern

Klimatpolitik och energisäkerhet: konflikter och synergier

För att begränsa risken för allvarliga klimatförändringar måste utsläppen av växthusgaser minskas kraftigt. Detta kommer att kräva en omställning av energisystemet där energieffektivisering och en ökad elektrifiering, förnybar energi, avskiljning och lagring av koldioxid samt kärnkraft kan få stor betydelse. I denna rapport analyseras hur en sådan omställning kan påverka olika aspekter av energi

Development of collective structures over noncollective excitations in Nd-139

High-spin states in Nd-139 were investigated using the reaction Zr-96(Ca-48,5n) at a beam energy of 195 MeV and gamma-ray coincidences were acquired with the Euroball spectrometer. Apart from several dipole bands at medium excitation energy, three quadrupole bands have been observed at high spin. Linking transitions connecting two of the high-spin bands to low-energy states have been observed. Cal

Recent advances in semiconductor nanowire heterostructures

Semiconductor nanowires have made a deep impact on materials science related research, and are being explored for applications in several disciplines. Many of these applications require heterostructures, which can be defined as the combination of two or more materials within the same nanowire structure. In this paper we briefly review the current state-of-the-art concerning epitaxial nanowire hete

Status of the Single Stage AMS machine at Lund University after 4 years of operation

The Lund SSAMS machine has been in routine operation since 2004. We present results from the last year of operation of the facility. The reference sample IAEA C7 and the "old" oxalic acid, Oxl, were used as secondary standards. As primary standard for calculations the OxII was used. The background and long term stability of the facility are discussed. We also report on the quality of the C-13/C-12
