Evaluation schemes, e.g., least-squares fitting, are not generally applicable to any types of experiments. If the evaluation schemes were not derived from a measurement model that properly described the experiment to be evaluated, poorer precision or accuracy than attainable from the measured data could result.. We outline ways in which statistical data evaluation schemes should be derived for all

The BRCA1 gene is thought to exert its main function early in life. We, therefore, studied the effects of BRCA1 mutations on birth weight and birth length. This was carried out by comparing 33 women with and without mutations. Birth weight and length were obtained from a self-administered questionnaire. BRCA1 mutations carriers had a significantly lower birth weight (P = 0.0041) compared with non-

A concentrating photovoltaic wall element, including Cu(In, Ga)Se-2-based modules, aluminum reflectors, and an insulation for building integration, has been developed and evaluated. The geometric concentration ratio of the system is about 3 x. However, the measured maximum electric power from the modules is only 1.9 times that of identical vertical modules without reflectors, due to optical losses

The nuclear microprobe (NMP) technique using PIXE for elemental analysis and STIM on/off axis for parallel mass density normalization has proven successful to investigate possible interactions between minerals and ectomycorrhizal (EM) mycelia that form symbiotic associations with forest trees. The ability for the EM to make elements biologically available from minerals and soil were compared in fi

Polysulfones carrying benzoyl(difluoromethylenephosphonic acid) side chains were prepared and investigated for use as proton-conducting fuel-cell membranes. In the first step, polysulfones were lithiated and reacted with methyl iodobenzoates to prepare p- and o-iodobenzoyl polysulfones. Next, the phosphonated polysulfones were prepared via CuBr-mediated cross-coupling reactions between the iodinat

An error exponent for woven convolutional codes (WCC) with one tailbiting component code is derived. This error exponent is compared with that of the original WCC. It is shown that for WCC with outer warp, a better error exponent is obtained if the inner code is terminated with the tailbiting method. Furthermore, it is shown that the decoding error probability decreases exponentially with the squa

Objectives. To assess waiting times for three groups of orthopaedic patients in Sweden and to identify factors explaining variations in waiting time. Also examined were factors associated with patients' perceptions that waiting times were too long. Design. Retrospective study. Setting and study participants. Patients from orthopaedic units at 10 Swedish hospitals participated in the study. A quest

Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. However, the field is still open

Rat models are useful for studies of the pathogenesis of rheumatoid arthritis (RA) since rats are extraordinarily sensitive to induction of arthritis with adjuvants. Injection of not only the classical complete Freund's adjuvant but also mineral oil without mycobacteria and pure adjuvants such as pristane and squalene, induce severe arthritis in many rat strains. Models like pristane-induced arthr

PURPOSE: To describe a component-based aortomonoiliac stent-graft system and the first clinical results achieved with this device in endovascular abdominal aortic aneurysm (AAA) repair. METHODS: From November 1993 to October 1996, 45 patients aged 60 to 86 years underwent endoluminal exclusion of true AAAs (median diameter 60 mm) involving the common iliac arteries (median diameter 16 mm right and

Aims and objective. To evaluate patient- reported health outcomes of a multidisciplinary group educational programme for people with Parkinson's disease ( PD), delivered as part of routine clinical practice. Background. Studies suggest that educational programmes for people with PD have potential to improve patients' perceived health and well- being. However, controlled trials of multidisciplinary

This paper describes the development of a prototype product named MAGIC-HAND that has been developed to open bottles, jars and packages that require a twisting action. Its intended users are people with severe disabilities, who are not capable of using the current range of package opening tools. MAGIC-HAND is a kitchen accessory device that fits into standard kitchen furniture. The machine uses no

An improved Volume of Fluid (VOF) method is presented which is applicable to high density ratio 3D flows for a large range of bubble Reynolds number (Re). The method is based on the Navier-Stokes equations for incompressible multi-phase flows which are discretized on a Cartesian staggered grid. The multi-grid technique together with the pressure-velocity coupling scheme for multi-phase flows have

Purpose : To study how patients with fibromyalgia (FM) experienced physiotherapy group treatment comprising pool exercise and education. Method : Nineteen patients with FM were interviewed and the transcribed interviews were analysed using a phenomenological life-world approach. The participants' mean age was 45 years and their mean symptom duration was 10 years. Results : Physiotherapy group trea

This study investigates utilization of the Internet in the rehabilitation of people on long-term sick leave with chronic pain and/or burnout. Fifty-five people were randomly assigned to two groups: a treatment group (n = 27) that participated in a rehabilitation course over the Internet and a waiting list group (n = 28). The goals were to improve participants' health and increase quality of life,

This paper presents the preliminary evaluation of different powered-wheelchair control modes for individuals with severe motor impediments. To this end, a C400 Permobil wheelchair has been updated with a control command communication interface and equipped with a scanning laser sensor to carry out the automation algorithms that are part of the robot operating system framework. A pilot test was per

To fulfill increasing requirements within the manufacturing sector, highly flexible and adaptable automation systems are needed. It is desirable to have one integrated approach that stretches from the process planning phase, through the implementation phase and all the way to the phase for execution of the process control logics. One promising approach is to use the concepts of service-oriented ar
