The LINC transmitter is an architecture that provides linear amplification using nonlinear but power efficient amplifiers. One crucial signal processing function of LINC is the signal component separator (SCS) which forms two constant-amplitude phase-modulated signals from the source signal. This paper presents an analog SCS chip implemented in a 0.35 mum CMOS process using a novel design based on
Backgrounds and Objectives Fresh frozen human plasma is an important raw material in the production of coagulation factor concentrates used in patients with haemorrhagic disorders. The aim of the study was to determine how the handling of plasma influences the recovery of coagulation factor VIII activity (FVIII:C), i.e. the influence of time between donation and freezing, of the freezing time and
In this study, the effects of cation-binding agents used alone and/or in combination with enzymes on solubilisation of municipal sludge and structure changes were investigated. Formic acid, citric acid, tartaric acid, EDTA, sodium tripolyphosphate (STPP), Zeolite A, sodium fluoride, sodium thiosulphate or sodium silicate were added to both biological and digested sludges. Citric acid ( 50 mmol/l)
In an investigation by the Swedish Cancer Society, the present status, critical issues and future aspects and potentials were described by an expert group for each of nine major areas of radiation therapy research. The present report deals with the potential of proton and light ion beams in radiotherapy.
The paper discusses the pros and cons of inductive research methods. It is argued that, despite the profusion of good arguments against this scientific strategy, it is frequently employed, for example in psychology. A case probe taken from the realm of cognitive psychology is used as an illustration.
We currently are witnessing a serious attrition of physicians specializing in hemophilia treatment in Europe and the United States while most physicians who complete training in hematology-oncology choose oncology practice as their career. Nevertheless, recent therapeutic developments, including advances in prophylaxis and inhibitor management, have renewed the demand for experts in hemophilia and
Objective: The objective of this article was to review some methodological issues in this field and give an overview of empirical research findings with a special focus on factors associated with or affecting subjective quality of life in people with a severe mental illness. Method: A selective review of relevant scientific literature on quality of life in severe mental illness was conducted. Resu
Ketosis-prone diabetes is heterogeneous. Its causes could include novel beta-cell functional defects. To characterize such defects, 103 patients with diabetic ketoacidosis were evaluated for beta-cell autoimmunity and human leukocyte antigen (HLA) class II alleles, with longitudinal measurements of beta-cell function and biochemical and clinical parameters. They were classified into four A beta gr
It is out of QoS reasons advisable for cellular operators to give higher priority to already ongoing connections than new call attempts. This can be achieved by having bandwidth in each cell exclusively reserved for these calls. Herein, a method for dynamically determining the size of the reserved bandwidth in UMTS networks, called Zone-based Reservation Scheme (ZRS), is introduced. For this purpo
Specialiteten njurmedicin omfattar prevention, diagnostik och behandling av parenkymatös njursjukdom. Målsättningen är att förhindra kronisk njursvikt, uremi. Men om terminal njursvikt skulle uppstå erbjuds så kallas aktiv uremivård, dvs dialys och njurtransplantation. I temat diskuteras olika aspekter av den aktiva uremivården i Sverige.
The influence of external precipitating factors and the presence of peripheral neuropathy on the development and outcome of foot ulcers were evaluated in 314 consecutive diabetic patients. All patients were treated by the same foot care team. Each patient was represented by one ulcer, and primary healing was defined as intact skin for at least six months. External precipitating factors were identi
Combined quantum chemical and molecular mechanics geometry optimisations have been performed on myoglobin without or with O(2) or CO bound to the haem group. The results show that the distal histidine residue is protonated on the N(varepsilon2) atom and forms a hydrogen bond to the haem ligand both in the O(2) and the CO complexes. We have also re-refined the crystal structure of CO-myoglobin by a
Calculating single-particle (Nilsson) levels in axially symmetric quadrupole-deformed potentials in coordinate space, the structure of weakly bound neutron orbits is studied in the absence of pair correlation. It is shown that in the wave functions of Omega(pi)=1/2(+) orbits, where Omega expresses the projection of the particle angular momentum along the symmetry axis, the l=0 (s(1/2)) component b
Since the cloning in 1990 of cDNA corresponding to mRNA transcribed at the blood group ABO locus, polymorphisms at the ABO locus and phenotype-genotype correlation have been analysed by several investigators. An enhancer-active minisatellite motif reported to contain four 43-bp repeats has been analysed by PCR in blood samples from 160 random Swedish blood donors. Different sizes of the DNA fragme
