A frequency synthesizer applied to 1000Base-T Ethernet transceiver as well as 10/100Base-T mode is described. A dynamic voltage-mode phase interpolator is used and a more precise analysis and calculation on degressive interpolating resistors are given. The design not only meets the transmitter's requirement of very accurate rising (falling) edge control but also offers much finer time-interval clo
Background Gastrostomy placement in children is one of the most frequently performed pediatric surgical procedures and laparoscopic-assisted gastrostomy (LAG) is the preferred technique. Wound infection after LAG has become a significant concern due to the emergence of antibiotic resistance. The aim of this study was to describe the frequency of wound infection after LAG in children younger than
By using dislocation simulation approach, the basic equation was formulated. A novel expansion method was proposed for solving the problem. The complete solution to the problem, including the explicit formulae for the T stresses ahead of the crack tip and the stress intensity factors were presented. The stress field characteristics were analysed in detail. It is found that the normal stresses ahea
We tested the reliability and construct validity of the Compatible magnetic resonance imaging (MRI) scale for the evaluation of haemophilic knees and ankles and compared the diagnostic performance of MRI and plain film radiographs. Sagittal and coronal gradient-echo 1.5-T MR images of knees (n = 22) and ankles (n = 23) were obtained from boys (age range 4-16 years; mean 11 years) in two centres (T
Case studies have claimed that private consumption growth is higher during fiscal contractions due to the very fact that government spending is cut. Indeed, neoclassical theory has this implication. This paper uses regression analysis of a panel of 19 OECD countries and shows that this is not true in general. On the contrary, contraction (expansion) periods experience lower (higher) private consum
OBJECTIVE : To evaluate the efficacy and safety of therapy for patients with histologically mild hepatitis C virus (HCV) liver disease. DESIGN : A randomized, double blind, placebo controlled trial of interferon alpha-2b with or without ribavirin. SETTING : Regional and university hospitals. PARTICIPANTS : One hundred and sixteen treatment naive patients with mild chronic HCV infection. Mild HCV i
In 1782, Jon Petursson, a district physician in Northern Iceland, published a textbook on arthritis and its remedies intended for common use. Working within a very simple diagnostic system, essentially comprising osteoarthritis (arthritis h a ) and inflammatory arthritis (arthritis vaga), he describes arthritis vaga as a common, chronic, symmetric, destructive, inflammatory polyarthritis, sometime
Background: Hip pain is prevalent in children with cerebral palsy (CP). Hip displacement is a known risk factor for hip pain. However, many children do not have displaced hips but still have hip pain and the aetiologies are poorly understood. The aims of this study were to investigate: 1. the prevalence of hip pain related to age, gender, gross motor function, degree of hip displacement and 2. the
Background: Individuals with knee and hip osteoarthritis (OA) are less physically active than people in general, and many of these individuals have adopted a sedentary lifestyle. In this study we evaluate the outcome of education and supervised exercise on the level of physical activity in individuals with knee or hip OA. We also evaluate the effect on pain, quality of life and self-efficacy. Meth
Background: Preoperative alteration of T cell-mediated immunity as well as an altered immune response to surgical stress were found in long-term alcoholic patients. The aim of this study was to evaluate perioperative T cell-mediated immune parameters as well as cytokine release from whole blood cells after lipopolysaccharide stimulation and its association with postoperative infections. Methods: F
Background: Preeclampsia and fetal growth restriction share some pathophysiologic features and are both associated with placental insufficiency. Fetal cardiac remodeling has been described extensively in fetal growth restriction, whereas little is known about preeclampsia with a normally grown fetus. Objective: To describe fetal cardiac structure and function in pregnancies complicated by preeclam
A number of bioactive natural products have by chromatographic techniques been isolated from extracts of various fungi, and their structures have been determined by spectroscopic and chemical methods. In the screening of fungal extracts for the inhibition of the binding of various ligands to CNS receptors in rat striatal membrane preparations in vitro, bioassay-guided fractionation of extracts of
This dissertation aims to contribute to the study of the relationship between religion and politics and especially research about Islam and Muslims in Sweden. The thesis analyzes how Islam and Muslims are depicted in Swedish public policy debates between 1975–2010. The research questions are: How are Islam and Muslims described in Swedish public policy? Which questions and in what circumstances ar
The impossibility results of Bovens and Hartmann (2003) and Olsson (2005) call into question the strength of the connection between coherence and truth. As part of the inquiry into this alleged link, I define a notion of degree of truth-conduciveness, relevant for measuring the usefulness of coherence measures as rules-of-thumb for assigning probabilities in situations of partial knowledge. I use
