Non-stoichiometry defects and radiation hardness of lead tungstate crystals PbWO4

It has been stated many times that the formation of radiation infringements in PbWO4 is to a big extent stipulated by the non-stoichiometry defects of the crystals, arising in the process of their growth and annealing. To refine the idea of characteristics of the non-stoichiometry defects and their effect on the radiation hardness of PbWO4, the current study is aimed at the melt composition infrin

Development and validation of a consensus methodology for the classification of the ANCA-associated vasculitides and polyarteritis nodosa for epidemiological studies

Background: The classification of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and polyarteritis nodosa (PAN) for epidemiology studies is confusing. The existing schemes such as American College of Rheumatology (ACR) criteria, Chapel Hill Consensus Conference (CHCC) definitions and Lanham criteria produce overlapping and conflicting classifications, making it difficult to compar

Jet identification based on probability calculations using Bayes' theorem

The problem of identifying jets at CERN LEP and DESY HERA is studied. Identification using jet energies and fragmentation properties is treated separately in order to investigate the degree of quark-gluon separation that can be achieved by either of these approaches. In the case of the fragmentation-based identification, a neural network is used, and a test of the dependence on the jet production

PIXE analysis to estimate the elemental composition of ectomycorrhizal rhizomorphs grown in contact with different minerals in forest soil

The aim of this study was to investigate possible interactions between minerals and ectomycorrhizal (EM) mycelia. Fungal rhizomorphs growing in association with apatite and/or biotite were sampled both from a laboratory experimental system (Rhizopogon sp. and Pinus muricata) and from mesh bags buried in forest soil in the field. The elemental composition of the samples was analyzed with particle-i

Intellectual Capital Disclosure through Annual Reports: A Study of the Swedish Retail Industry

This article is based on a content analysis of intellectual capital (IC) in annual reports from 1998 to 2002. The aim of the study was to compare the content of voluntary information on IC in the corporate annual reports covering a period of 4 years. The results from the study, based on 15 Swedish companies in the retail sector, show that for the year 2002 the information on human capital in the a

Neuronal integration in an abutting-retinas culture system

PURPOSE: Limited integration is consistently observed between subretinal transplants and host retinas. In the current study, an in vitro model system for studying connections forming between two abutting retinas was developed.METHODS: Neuroretinas were dissected from normal wild-type (WT) mice and green fluorescent protein (GFP) transgenic mice (obtained at postnatal days [P]0, P5, or P60), as wel

All in the family [Review of the motion picture Requiem]

Reviews the film, Requiem, directed by Hans-Christian Schmid (2006). This award-winning (for both its star, Sandra Hüller, and the film itself) German film is based on the case of Anneliese Michel, a 23-year-old German woman who died in 1976, probably of starvation (she weighed 68 lb. just before her death) and exhaustion, after 67 exorcism rites. Hüller's nuanced performance chills the spine far

Measurement of inclusive jet cross sections in photoproduction at HERA

Inclusive jet cross sections are measured in photoproduction at HERA using the H1 detector. The data sample of e(+)p --> e(+) + jet + X events in the kinematic range of photon virtualities Q(2) less than or equal to 1GeV(2) and photon-proton centre-of-mass energies 95 less than or equal to W-gammap less than or equal to 285GeV represents an integrated luminosity of 24.1pb(-1). Jets are defined usi

Steam and Condensate System Control in Paper Making

The function of a paper machine is to form the paper sheet and remove the water from the sheet. A modern paper machine is divided into three main parts, the wire section, the press section, and the dryer section. Although the dryer section is only responsible for removing less than 1% of the water volume in the original stock to the head box, this is the part of the paper machine that, by far, con

Decrease in high density lipoprotein cholesterol during prolonged storage. CELL Study Group

Different studies on the stability of high density lipoprotein cholesterol (HDL) in frozen serum or plasma have yielded conflicting results, namely increase, decrease, or no change at all during prolonged storage under freezing conditions. As part of a major trial on lipid-lowering strategies we statistically demonstrated a time-related decrease in HDL cholesterol during storage up to 46 months at

A review of the production of ethanol from softwood

Ethanol produced from various lignocellulosic materials such as wood, agricultural and forest residues has the potential to be a valuable substitute for, or complement to, gasoline. One of the major resources in the Northern hemisphere is softwood. This paper reviews the current status of the technology for ethanol production from softwood, with focus on hemicellulose and cellulose hydrolysis, whi

Sphingosine 1-phosphate antagonizes human neutrophil apoptosis via p38 mitogen-activated protein kinase.

Sphingosine 1-phosphate (SPP) is associated with the regulation of apoptosis, although its role in neutrophil apoptosis remains poorly investigated. Here, we show that exogenous SPP antagonizes spontaneous and anti-Fas-induced apoptosis in neutrophils. Pre-treatment with pertussis toxin clearly reduced the apoptosis-inhibiting capacity of SPP. Consequently, we investigated the involvement of poten

PLASMA PROTEINS IN NORMAL AND PREECLAMPTIC PREGNANCY

Popular Abstract in Swedish Havandeskapsförgiftning (preeklampsi) är ett allvarligt risktillstånd som uppkommer vid 1.5-2.0 % av alla graviditeter och sjukdomen är en av de största orsakerna till mödra- och barndödlighet i världen. Preeklampsi karaktäriseras av högt blodtryck och läckage av äggvita i urinen under sista hälften av graviditeten hos en tidigare frisk kvinna. Njurarna spelar en avgöraThe aim of the research presented in this thesis was to provide extended background knowledge concerning several biochemical markers, used for the medical evaluation of pregnant women with suspected or confirmed preeclampsia, in order to improve the reliability of monitoring. Plasma levels of beta-2 microglobulin, cystatin C and beta trace protein are known to reflect renal filtration in non-pregn

Plant-wide (BSM2) evaluation of reject water treatment with a SHARON-Anammox process

In wastewater treatment plants (WWTPs) equipped with sludge digestion and dewatering systems, the reject water originating from these facilities contributes significantly to the nitrogen load of the activated sludge tanks, to which it is typically recycled. In this paper, the impact of reject water streams on the performance of a WWTP is assessed in a simulation study, using the Benchmark Simulati
