Purpose Population-based studies on violent crime and background factors may provide an understanding of the relationships between susceptibility factors and crime. We aimed to determine the distribution of violent crime convictions in the Swedish population 1973-2004 and to identify criminal, academic, parental, and psychiatric risk factors for persistence in violent crime. Method The nationwide
OBJECTIVE: To assess whether intravascular ultrasound (IVUS), used systematically in a series of patients with abdominal aortic aneurysms (AAA), is a feasible control procedure to ensure correct transfemoral placement of endovascular stent grafts (TPEG). DESIGN: Descriptive study. MATERIALS AND METHODS: Fourteen patients with infrarenal aortic aneurysms were treated by the placement of one tube gr
Insertion of metals into various tetrapyrroles is catalysed by a group of enzymes called chelatases, e.g. nickel, cobalt, magnesium and ferrochelatase. It has been proposed that catalytic metallation includes distorting the porphyrin substrate by the enzyme towards a transition state-like geometry in which at least one of the pyrrole rings will be available for metal chelation. Here, we present a
An experiment has been performed to search for superdeformed (SD) states in Dy-149,Dy-150. While no evidence for discrete superdeformed states has been observed, a superdeformed ridge with a separation of Delta E-gamma=52 keV with a total intensity of 1.8+/-0.5% that of Dy-150 has been observed. An upper limit of 0.8% (0.9%), of the intensity of Dy-150 (Dy-149), is placed for observation of the mo
Triglycerides and phospholipids 0.5-2mg (wet weight) of human liver material obtained by the fine-needle aspiration biopsy technique can be estimated after chloroform:methanol extraction by the determination of lipid phosphorus and glyceride glycerol. The methods are based on the colorimetric determination of inorganic phosphate after oxidation of the phospholipids and the enzymatic fluorometric d
A transmitter consisting of a voltage controlled oscillator (VCO) and power amplifier (PA) for the 400 MHz Medical Implanted Communication System band (MICS) was built in a standard 0.35-μm CMOS process. A push pull architecture was used for both the VCO and the PA. Two off-chip inductors were needed. The design was optimized for 400 μW output power at 3 V supply, which resulted in an efficiency o
In this paper ethical implications of parental participation in paediatric care are discussed. The paper is based on interviews with 20 parents, whose children were admitted and operated on at a paediatric surgery department in Sweden. In one part of the interview the parent was invited to speak about situations experienced as problematic during the hospitalization. Three different types of situat
Parkinson's disease (PD) is the most common movement disorder. The neuropathology is characterized by the loss of dopamine neurons in the substantia nigra pars compacta. Transplants of fetal/embryonic midbrain tissue have exhibited some beneficial clinical effects in open-label trials. Neural grafting has, however, not become a standard treatment for several reasons. First, the supply of donor cel
This paper presents an analysis of the Ziegler-Nichols frequency response method for tuning PI controllers, showing that this method has severe limitations. The limitations can be overcome by a simple modification for processes where the time delay is not too short. By a major modification it is possible to obtain new tuning rules that also cover processes that are lag dominated.
The nitrogen (N) cycle contains two different processes of dissimilatory nitrate (NO(3)(-)) reduction, denitrification and dissimilatory NO(3)(-) reduction to ammonium (DNRA). While there is general agreement that the denitrification process takes place in many soils, the occurrence and importance of DNRA is generally not considered. Two approaches have been used to investigate DNRA in soil, (1) m
For triangles with linear vertex motion, common practice is to backface cull a triangle if it is backfacing at both the start and end of the motion. However, this is not conservative. We derive conservative tests that guarantee that a moving triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and o
It is well known that in the context of the classical regression model with heteroskedastic errors, while ordinary least squares (OLS) is not efficient, the weighted least squares (WLS) and quasi-maximum likelihood (QML) estimators that utilize the information contained in the heteroskedasticity are. In the context of unit root testing with conditional heteroskedasticity, while intuition suggests
Because information about the livelihoods of indigenous groups in Africa is often missing from colonial records, the presence of such people usually escapes attention in quantitative estimates of colonial economic activity. This is nowhere more apparent than in the eighteenth-century Dutch Cape Colony, where the role of the Khoesan in Cape production, despite being frequently acknowledged, has bee
