Context: Despite the substantive societal impact of prostate cancer, the medical community is currently divided on the balance between benefit and harm of screening for prostate cancer using prostate-specific antigen (PSA). Objective: To examine whether PSA-based screening for prostate cancer meets current guidelines on efficacy and effectiveness for screening, and how it compares with other curre
The expression levels of fetal hemoglobin (HbF) in bacterial recombinant systems are higher compared with normal adult hemoglobin (HbA). However, heme disorientation in globins are often observed in recombinant production processes, both for HbA and HbF, although the degree of heme oriental disorder is much lower for HbF. In addition, the heme disorientation can be converted to a normal conformati
Based on an extensive cohort study over 25 years, the present study supports the assumption that major osteoporotic fractures can be reasonably predicted from hip fracture rates. The construct for FRAX models depends on algorithms to adjust for double counting of fracture outcomes in some models and in others, to estimate the incidence of a major fracture from hip fracture rates. The aim of the pr
Abstract in Undeterminedhe paper is based on selected findings of the research project EEC 2092/91 (Organic) revision. It contributes to an improved understanding of the core ethical values associated with and principles of organic farming, analyses reference to such values in the European Regulation (EEC) 2092/91 and its ongoing revision, and contrasts them with current practice of organic agricu
Aim Understanding what constituted species ranges prior to large-scale human influence, and how past climate and land use change have affected range dynamics, provides conservation planners with important insights into how species may respond to future environmental change. Our aim here was to reconstruct the Holocene range of European bison (Bison bonasus) by combining a time-calibrated species d
This study uses a generalized linear model approach, i.e. negative binomial regression, to develop a predictive model for motorcycle fatal accidents on Malaysian primary roads. For the modeling process, a huge data inventory has been carried out, integrating the road geometry features, fatal accident records and traffic censuses from 3 selected states for the past 3-year period. The results show t
This article discusses opportunities and challenges of physical layer security integration in MaMIMO systems. Specifically, we first show that MaMIMO itself is robust against passive eavesdropping attacks. We then review a pilot contamination scheme that actively attacks the channel estimation process. This pilot contamination attack not only dramatically reduces the achievable secrecy capacity bu
Popular Abstract in Swedish Arbetsplatsens positiva sidor kan förbättras genom ett nytt dialogverktyg! Nu går det att mäta medarbetares positiva upplevelser av arbete. Vanligtvis kopplas människors upplevelser av arbete samman med stress och ohälsa. Men det går att tänka tvärtom, att istället fokusera på allt det positiva som arbete kan ge. När människor mår bra av sitt arbete, blir de också mer The aim of this thesis was to develop and make a quality assessment of a tool, which includes a questionnaire and a dialogue process that could be useful for workplace health promotion from a salutogenic point of view. The studies have been performed within two health care organizations between 2005 and 2009, together with hospital staff. Two questionnaire studies were conducted (n=446 n=505, resp
In this work, we discuss the possibility of a new approach to measuring oxygen isotope ratios in fossil meteorite samples, specifically one based on nuclear reaction analysis (NRA). Variations of oxygen ratios within meteoritic chromite grains can help to determine the type of meteorite to which the grains originally belonged. In this work, we have evaluated the possibility to use the reaction O-1
The dynamics and consequences of host-parasite coevolution depend on the nature of host genotype-by-parasite genotype interactions (G × G) for host and parasite fitness. G × G with crossing reaction norms can yield cyclic dynamics of allele frequencies ("Red Queen" dynamics) while G × G where the variance among host genotypes differs between parasite genotypes results in selective sweeps ("arms ra
When developing software-intensive products for a market-place it is important for a development organisation to create innovative features for coming releases in order to achieve advantage over competitors. This paper focuses on assessment of innovation capability at team level in relation to the requirements engineering that is taking place before the actual product development projects are deci
The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with a 180 deg turns under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase blade tip lifetime. Pin
A search for the production of single top-quarks via flavour-changing neutral-currents is presented. Data collected with the ATLAS detector at a centre-of-mass energy of root s = 7 TeV, corresponding to an integrated luminosity of 2.05 fb(-1), are used. Candidate events with a semileptonic top-quark decay signature are classified as signal- or background-like events by using several kinematic vari
Upper limits on direct photon production were determined as a function of the transverse momentum for 0.7 < pT ≤ 3.2 GeV/c with the WA98 experiment in p + C and p + Pb collisions at . The results are compared to direct photon measurements in Pb + Pb collisions at by WA98. Implications for a possible thermal direct photon contribution are discussed.
In the beginning of the 1990s, Sweden experienced an economic recession. The unemployment rate increased significantly and the proportion of young adults receiving social assistance rose dra-matically. In response, municipalities initiated local intervention programs aimed at reducing the number of young social assistance recipients. In 2005, this population had decreased. However, the organizatio
The essence of the chemical mechanism for surface-enhanced resonance Raman scattering (SERRS) is the charge transfer (CT) between the metal and the molecule at the resonant electronic transition, which results in the mode-selective enhancement in the SERRS spectrum. The site-orientated CT can directly interpret the mode-selective chemical enhancement in SERRS. However, it is a great challenge to i
