Background: In 2007, the World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) issued recommendations on diet, physical activity, and weight management for cancer prevention on the basis of the most comprehensive collection of available evidence. Objective: We investigated whether concordance with WCRF/AICR recommendations is related to risk of death. Design: The
This booklet is a report for a case study visit during four day field trip, a group of nine PhD students and their supervisors – all part of the National Research School for Architecture and Planning in the Urban Landscape, APULA – set out to explore what may be considered the outback of Western Europe’s conurbations, the transnational region of Kiruna -Narvik.Both “remote” and “resourceful”, “thr
Dose calculations for treatment planning of photon beam radiotherapy require a model of the beam to drive the dose calculation models. The beam shaping process involves scattering and filtering that yield radiation components which vary with collimator settings. The necessity to model these components has motivated the development of multisource beam models. We describe and evaluate clinical photo
The thesis is based on applied research, rather closed to industrial development. The developed simulation model, for pre-design of evaporative gas turbine cycles, has been validated in a 600 kW pilot plant and in rebuilt turbo-charged diesel engines. Besides of the work with the thesis including theoretical modelling and hardware development concerning wet cycles, the work has also resulted in th
This article provides 12-month prevalence rates of youth exposure to websites which encourage self-harm or suicide and examines whether such exposure is related to thoughts of self-harm and thoughts of suicide in the past 30 days. Data were collected via telephone from a nationally representative survey of 1560 Internet-using youth, ages 10-17 residing in the United States. One percent (95% CI: 0.
Introduction. Limited information is available concerning the general and sexual health status of European men. Aim. To investigate the age-related changes in general and sexual health in middle-aged and older men from different countries of the European Union. Methods. This is a cross-sectional multicenter survey performed on a sample of 3,369 community-dwelling men aged 40-79 years old (mean 60
To develop a risk prediction model to preoperatively discriminate between benign, borderline, stage I invasive, stage II-IV invasive, and secondary metastatic ovarian tumours.
The demand for information and transparency from corporations has increased over the last few years. Today, there are other information dissemination channels besides annual financial statements. One important channel is the Internet. The aim of this study is to explain the extent and content of social disclosure information on corporations' websites. The empirical data in this study is based on a
The human B1 bradykinin (BK) receptor (B1R) is more efficacious than the human B2 BK receptor (B2R) in both ligand-independent and agonist-dependent coupling to Gq/11-mediated phospholipase Cbeta activity. In fact, B1R is constitutively active, whereas B2R exhibits little if any constitutive activity. To evaluate the role of the C-terminal domain in receptor Gq/11 coupling, we constructed chimeric
The article investigates translation culture in the Swedish dominion Swedish Pomerania during the eighteenth century, with a particular focus on periodicals.
In about four decades, ion beam analysis (IBA) techniques have evolved to become well established analytical techniques for routine analysis in archaeological, bio-medical, geological and environmental sciences. They basically make use of the different interactions of a high energy ion beam (of few MeV/amu) with the specimen matter so they pressupose the use of a particle accelerator. In laborator
Over the years consumer packaging has become increasingly important as a value-adding element, since packages shape the consumer’s experience with the product during use, as well as accelerate the purchase decision. From a prod-uct/service system perspective, the strategic benefits of viewing packaging as a central value carrier are evident. To consumers, the product and its packaging are often pe
Great expectations have been raised about neuroprotection of therapeutic hypothermia in patients with traumatic brain injury (TBI) by analogy with its effects after heart arrest, neonatal asphyxia, and drowning in cold water. The aim of this study is to review our present knowledge of the effect of therapeutic hypothermia on outcome in children and adults with severe TBI. A literature search for r
The worldwide incidence of gastric adenocarcinoma (GC) is lower in women than in men. Furthermore, cancer patients treated with estrogens have been reported to have a lower subsequent risk of GC. The authors conducted a prospective analysis of menstrual and reproductive factors, exogenous hormone use, and GC in 335,216 women from the European Prospective Investigation Into Cancer and Nutrition, a
Background Experimental animal studies and previous randomized trials suggest an improvement in mortality and neurologic function with induced hypothermia after cardiac arrest. International guidelines advocate the use of a target temperature management of 32 degrees C to 34 degrees C for 12 to 24 hours after resuscitation from out-of-hospital cardiac arrest. A systematic review indicates that the
Popular Abstract in Swedish Denna avhandling behandlar analys och förbättringar av en metod att mäta blödgenomströmning i vävnad med kontinuerlig ultraljudsdoppler. Tidigare har stora variationer i detekterat perfusionsvärde observerats som en effekt av speckle, eller våginterferens. Här presenteras en teoretisk modell som förklarar specklefenomenet i en sådan mätsituation. Modellen förutsäger deThis thesis has the main focus on ways to improve the blood perfusion estimate, as obtained from a continuous wave Doppler system. Earlier studies have shown large temporal variations in the detected perfusion estimate, due to speckle. Here, a theoretical model to predict frequency dependent characteristics of speckle in continuous wave ultrasound is presented. The model predicts the frequency shi
The reaction between pyrite (natural iron (II) disulfide) powder and potassium alkylxanthate has been studied in aqueous solution. Qualitative analysis of the compounds present on pyrite surfaces before and after treatment with ethylxanthate ions under different oxidation conditions has been performed by means of diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy. Atomic absorptio
Efficient inventory control depends on correct values of inventory cost parameters, such as holding costs, shortage/stockout costs and ordering/setup costs. However, there exists surprisingly little research concerning the size of these parameters or how they should be determined. This thesis is devoted to increasing our knowledge of these matters. The research is presented in the form of five sc
