Diagnostic accuracy and potential clinical value of the LightCycler SeptiFast assay in the management of bloodstream infections occurring in neutrope…

2011

Summary Objectives The objectives of this study were to compare the performance of the LightCycler SeptiFast Test MGRADE and conventional blood culture in the etiological diagnosis of febrile episodes occurring in neutropenic and critically ill patients (in the intensive care unit; ICU), and to assess the potential clinical value of the SeptiFast test in patient management. Methods A total of 86 febrile episodes occurring in 33 neutropenic patients and 53 ICU patients were analyzed. Blood samples for blood culture and SeptiFast testing were obtained at the onset of fever, before the implementation of empirical antimicrobial therapy. Results The overall microorganism-to-isolate agreement bet…

Occurrence of aflatoxins in feedstuff, sheep milk and dairy products in Western Sicily

2003

Samples of feedstuffs (15), milk (40), and cheese (30) coming from sheep and dairy farms (23) or market in WesternSicily were analyzed for their respective content of aflatoxin B1 (AFB1) and M1 (AFM1) to evidence any possible indirectmycotoxin contamination risk to the consumer. Analyses using HPLC and fluorescence detection were performed afterimmunoaffinity column sample extraction and cleanup; AFM1 was detected in 30% of the milk samples at levels rangingfrom 4 to 23 ng/l and in 13% of the cheeses from 21 to 101 ng/kg; in the feed the AFB1 ranged from None of the contaminated samples exceeded the legal limits set down by the European Union for milk (50 ng/l) and feed(5 μg/kg ), or tha…

Vil økt fysisk aktivitet kunne redusere andelen trygdemottakere? : En case-studie basert på deltakere ved Aktiv på dagtid, Aust-Agder

2018

Masteroppgave offentlig politikk og ledelse ME502 - Universitetet i Agder 2018 This study is based on Aktiv pådagtid as an case study. The purpose of this study is to investigate the relationship between increased participation in physical activities directed by Aktiv på dagtid and the participants status in relation to working life. To better understand the relationship between these two variables, the study include three possible predictors:health, social support and self-efficacy.Thisstudy use a paper-based survey with 144 respondents, which represent the participants atAktiv på dagtid, who are at theage between 16-70, receive social security benefits and resides in the municipalities of…

The Relevance of Mineral Mobilization and -Dissolution on the Reservoir Quality of Sandstones in CO2 Storage Sites

2014

Abstract Rotliegend siliciclastic formations are important reservoirs in central Europe. These sediments consist of pristine red coloured and bleached, high porous and permeable sandstones. To evaluate the relevance of distinct fluids and their fluid-rock alteration reactions on such bleaching processes laboratory static batch experiments under reservoir conditions were conducted. Thereby mineralogical, petrophysical and (hydro-, geo-) chemical rock features were investigated by different analytical methods before and after the experiments. The achieved results suggest that during such fluid-rock interactions a complex interplay between mineral detachment and mineral dissolution processes w…

Astrophysical bound on the majoron-Higgs-boson coupling

1989

Abstract We show that the coupling of the “standard” Higgs boson to majorons, that could lead to a very fast decay of the neutral Higgs scalar to invisible modes, can be bounded using astrophysical arguments. We discuss the relevance of this bound for low-energy phenomenology related to majoron production. The bound so obtained may also jeopardize the stability of the VEV hierarchy in the doublet and triplet majoron models if the mass of the top quark is less than the W mass. A similar analysis may be applied to other models which exhibit Goldstone-or pseudo-Goldstone-bosons in the spectrum.

Search for a light exotic particle inJ/ψradiative decays

2012

Using a data sample containing 1.06x10^8 psi' events collected with the BESIII detector at the BEPCII electron-positron collider, we search for a light exotic particle X in the process psi' -> pi^+ pi^- J/psi, J/psi -> gamma X, X -> mu^+ mu^-. This light particle X could be a Higgs-like boson A^0, a spin-1 U boson, or a pseudoscalar sgoldstino particle. In this analysis, we find no evidence for any mu^+mu^- mass peak between the mass threshold and 3.0 GeV/c^2. We set 90%-confidence-level upper limits on the product-branching fractions for J/psi -> gamma A^0, A^0 -> mu^+ mu^- which range from 4x10^{-7} to 2.1x10^{-5}, depending on the mass of A^0, for M(A^0)<3.0 GeV/c^2. On…

Low energy properties of color-flavor locked superconductors

2005

We discuss some low energy properties of color-flavor locked (CFL) superconductors. First, we study how an external magnetic field affects their Goldstone physics in the chiral limit, stressing that there is a long-range component of the field that penetrates the superconductor. We note that the most remarkable effect of the applied field is giving a mass to the charged pions and kaons. By estimating this effect, we see that for values $e B \sim 2 f_\pi \Delta$, where $\Delta$ is the quark gap, and $f_\pi$ the pion decay constant, the charged Goldstone bosons become so heavy, that they turn out to be unstable. The symmetry breaking pattern is then changed, agreeing with that of the magnetic…

Reforms and decentralization: friends or foes

2013

Systemic concerns about markets, capitalism and the role of the state in the economy are salient again. Relatively large-scale reforms of economic and social arrangements are seriously considered. Historical experience suggests that reforms of that kind are sometimes associated with important changes in institutional arrangements pertaining to political decentralization. To explore the relationship between economic reforms and decentralization, the paper argues that a reform has two dimensions. It is a process and it is a design. The organization of the paper is inspired by that distinction. For economists, it seems natural to reason in terms of design -- that is, to perceive reform as the …
