The influence of ionic environment on the rheological properties of aqueous cetyltrimethylammonium p-toluene sulfonate (CTAT) solutions has been studied under three different flow fields: simple shear, opposed-jets flow and porous media flow. Emphasis was placed in the experiments on a range of CTAT concentration in which wormlike micelles were formed. It is known that these solutions exhibit shea
This work is concerned with the adsorption of o-phthalate (1,2-benzenedicarboxylate) at the water-metal (hydr)oxide interface. Previously published infrared spectroscopic, potentiometric, and adsorption data characterizing the boehmite (gamma-AlOOH) system are compared with new data collected for o-phthalate adsorption on aged gamma-Al2O3 and goethite (alpha-FeOOH). The study focuses on identifyin
The dynamic crack growth in ductile steel is investigated by means of the impact loaded 3 point bending (3PB) specimens. Results from experiments and numerical simulations are compared to each other. A modified 3PB specimen designed with the reduced width at its ends has been developed in order to avoid the initial compressive loading of the crack tip and also to avoid the uncertain boundary condi
PURPOSE: This review aims to provide guidance in managing glaucoma patients more effectively. It focuses on the importance of detecting progression and measuring its rate within the management of primary open-angle glaucoma today. Recent findings strongly indicate that continued monitoring of visual fields (VFs) and reassessment of target intraocular pressures (IOPs) depending on VF progression ra
Excited state lifetimes of c(4)('1)Sigma (+)(u), upsilon = 0-2 states of molecular nitrogen have been determined in a laboratory investigation using a picosecond XUV laser in a pump-probe configuration. For c(4)('1)Sigma (+)(u) upsilon = 0 the lifetime is tau = 740 +/- 50 ps, for the lowest rotational states. For higher rotational states a gradual shift towards tau = 495 ps is found in agreement w
The dorsal-side-up body posture of standing quadrupeds is maintained by coordinated activity of all limbs. Somatosensory input from the limbs evokes postural responses when the supporting surface is perturbed. The aim of this study was to reveal the contribution of sensory inputs from individual limbs to the posture-related modulation of pyramidal tract neurons (PTNs) arising in the primary motor
The purpose of this thesis is to obtain microlocal analogues of results by L. Hörmander about inclusion relations between the ranges of first order differential operators with smooth coefficients which fail to be locally solvable. Using similar techniques, we shall study the properties of the range of classical pseudo-differential operators of principal type which fail to satisfy condition (ψ).
Inflammation is a well-established risk factor for the development of coronary artery disease (CAD) and acute coronary syndrome (ACS). However, less is known about its influence on the outcome of ACS. The aim of this study was to determine if blood biomarkers of inflammation were associated specifically with acute myocardial infarction (MI) or unstable angina (UA) in patients with ACS.
It has recently been reported that women treated with low molecular weight heparin (LMWH) during pregnancy had 3 h shorter duration of delivery. The aim of the present study was to evaluate whether LMWH (dalteparin) affects labour. From January 1996 to December 2005, 217 consecutive pregnancies, out of 34 216 newborn (prevalence 0.6%) that were given thromboprophylaxis with dalteparin (usually 5,0
BACKGROUND: Physical activity (PA) is part of a healthy lifestyle and prevents many chronic health problems, in addition to promoting mental health. PA performed outdoors has been found particularly good for promoting one's well-being. The aim of this study was to investigate the extent to which outdoor recreational PA was carried out during 1 year, and the factors influencing such activities from
What exactly are opinions? What does it mean to express an attitude? Given the ubiquitous use of surveys, polls and rating scales, it seems we ought to have firm answers to these fundamental questions, but we do not. Here we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and curr
Popular Abstract in Swedish Total parenteral nutrition (TPN) används för näringstillförsel till patienter som av olika orsaker inte kan försörja sig via sedvanligt födointag. Vid TPN tillföres fett, socker, aminosyror (proteinernas byggstenar), vitaminer och salter i mängder tillräckligt för att täcka det dagliga behovet. Näringsämnena tillföres via en blodåder och passerar således inte magtarmkanDuring total parenteral nutrition (TPN) adequate nutrition is provided intravenously and the enteral route is bypassed. The integrity of the gastrointestinal (GI) tract, however, is dependent on the passage of food through it. This thesis deals with the effects of TPN on the pancreas and the parotid glands. TPN induced hypotrophy of the exocrine pancreas and the parotid glands. The amylase concent
In this paper, we propose to perform remote laser-induced breakdown spectroscopy (LIBS) and Raman imaging of historical monuments to assess the state of a building. The lidar system is equipped with a Nd:YAG pumped optical parametrical oscillator (OPO) system, allowing laser radiation in the wavelength range 220 nm-4 μm. The laser radiation can be sent through a roof-top dome which can steer the r
A Relative Success? Notes on the circulation and wider reception of Scandinavian Crime In this paper Scandinavian crime, or Nordic Noir, in its filmic and televisual incarnations, will be considered on its relative merits as a transnationally successful, but regionally based popular cultural expression. The inquiry will be conducted against a backdrop which briefly traces the history and some of t
The incidence and prevalence of heart failure (HF) has increased successively over the past decade. Mortality and morbidity is high. It is the most common cause of hospitalisation in the elderly and has been estimated to account for 1-3% of health care costs in many countries. There is a need therefore, to improve care for HF patients. However, due to limited economic resources, this must be done
