This paper tests the null hypothesis of a zero effect of cesarean section rate on health outcome against the alternative of a positive effect. Using data from 59 hospitals in Sweden from 1988-92, we specify two separate linear regression models for health outcome, one with perinatal mortality, and the other with rate of asphyxia, as dependent variable. We estimate the models by single-year cross-s
Biorefineries are the backbone of “white biotechnology”, the 3rd wave of biotechnology which aims to replace classic C2/C3 chemistry by biotechnological processes. In analogy to petrorefineries biorefineries aim at the integrated and simultaneous production of bulk products, as e.g. biofuels, or biopolymers, heat and power, using biomass. In order to avoid any competition with food production the
The effects of the antinutrients tannic acid, catechin and phytic acid on digestion of starch, protein and lipids, and fiber degradation were studied in rat balance experiments. To separate digestion in the small intestine from fermentation in the hind‐gut, diets were tested without and with the addition of antibiotics. The antinutrients had no effects, either on starch digestion or on fiber ferme
This article addresses the question of whether globalization impacts individual preferences to exclude immigrants from national welfare systems ('welfare chauvinism'). Intergroup contact theory and arguments from the 'new cosmopolitanism' debate suggest that cross-border social contacts ('social globalization') foster a willingness to include and accept newcomers. However, group conflict theory su
Arguments in favour of strengthening the rights of victim–survivors in the criminal justice process have largely been made within the framework of a human rights perspective and with a view to meeting their procedural needs and minimising their experiences of secondary victimisation. In this article, however, I ask whether the prevalent legal arrangement, whereby victim–survivors are assigned the
The early Cambrian Sirius Passet fauna of northernmost Greenland (Cambrian Series 2, Stage 3) contains exceptionally preserved soft tissues that provide an important window to early animal evolution, while the surrounding sediment holds critical data on the palaeodepositional water-column chemistry. The present study combines palaeontological data with a multiproxy geochemical approach based on sa
Migratory songbirds are guided by an endogenous programme during their first migration, encoding timing of migration, distance and direction. To successfully perform migration, birds have evolved phenotypic adaptations for flight, fuelling and navigation. Migratory distance in different species of birds is encoded as a period of expressed migratory restlessness, for which the length is correlated
A sensitivity analysis on test outcomes from the microscale combustion calorimeter was performed using flexible polyurethane foam as the sample material. Three input factors were investigated: sample preparation, heating rate and pyrolysis chamber atmosphere. The experiments were setup according to the principles of design of experiments and a full factorial design was implemented. In total, 39 ex
Based on a modified force balance model, new correlations were proposed for the prediction of vapor bubble departure radius in saturated and subcooled pool boiling under atmospheric pressure. To predict the departure radius, the wall temperature and contact angle are two important input parameters. Instead of the static contact angle, the present correlations use the dynamic advancing contact angl
Surface deposited layers of mesoporous silica particles could function as support for bio-sensing or drug release applications. It is crucial to control the surface deposition process and employ relevant techniques to characterize the properties of the particles on the surface. Here, we deposit SBA-15 particles on native silica or cationic surfaces and characterize the hydration and dehydration by
Steel girders require stability controls for different construction stages before the lateral-torsional support from the concrete deck occurs. The load-carrying capacity of bridge girders and bracing forces generated in their bracings are very sensitive to the girders' initial imperfections in terms of both the magnitude and distribution along the span. Relatively little knowledge is available in
Purpose: Many centers aim to plan liver transarterial radioembolization (TARE) with dosimetry, even without CT-based attenuation correction (AC), or with unoptimized scatter correction (SC) methods. This work investigates the impact of presence vs absence of such corrections, and limited spatial resolution, on 3D dosimetry for TARE. Methods: Three voxelized phantoms were derived from CT images of
This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. The research draws on data collected through interviews and observations of older people in relation to three robots. The results show that older people’s domest
Background There is a great need for a simple and clinically useful instrument to help physicians estimate the probability of survival to discharge with a good neurological outcome (cerebral performance category, CPC = 1) in cases of in-hospital cardiac arrest (IHCA). Our aim was to validate the “Good Outcome Following Attempted Resuscitation” (GO-FAR) score in a different country with different d
The prescriptive approach to crisis communication strategy (CCS) selection has long been criticized for lack of flexibility and adaptability. To address this issue, this study proposes an emergent approach to strategy formulation by focusing on contextual impacts on social media crises and their implications for CCS. An online discussion on Sina Weibo, a Chinese microblogging platform, about a hig
The combustion process in a hydrogen fueled scramjet combustor with a rearwall-expansion cavity was investigated numerically under inflow conditions of Ma=2.52 with stagnation pressure P0=1.6 Mpa and stagnation temperature T0=1486 K. The numerical solver was first evaluated for supersonic reactive flows in a similar combustor configuration where experimental data is available. Wall-pressure distri
