Recently, new optical non-linear materials and frequency-mixing schemes have been developed. This has moved the frontiers of short-wavelength laser spectroscopy into the VUV spectral region. Spectroscopic methods suitable for short-wavelength laser sources are presented.
Objective. Serum calcium concentrations have been associated with the risk of malignant disease, especially breast cancer. Thus, determinants of serum calcium concentrations, with special regard to risk factors of breast cancer, are of great interest. Material and methods. Previous studies have either been small or they have not focused on reproductive factors. The present study examined serum cal
Abstract Objective. Prostate cancer antigen 3 in urine (uPCA3) has been shown to perform better than total prostate-specific antigen in serum (tPSA) to predict prostate cancer (PCa) detection. The aim of this study was to validate the diagnostic precision of uPCA3 in a mixed set of patients with no previous history of PCa, including patients with previous negative biopsies. Material and methods. T
Through a sociological case study this article analyses how, seen from a relational perspective, everyday life for elderly people receiving care in their own homes is lived with dependence on health-care professionals. The healthcare professionals’ time and tasks are assigned and allocated in advance so that the elderly people are neither allowed nor able to vary their response in relation to the
BACKGROUND: Disease severity in Mycoplasma pneumoniae (MP) infection could potentially be related to bacterial factors such as MP genotype (MP1 or MP2; distinguished by different adhesions proteins) or bacterial load in airway secretions. We have compared these parameters in patients who were hospitalized for MP pneumonia, with outpatients with mild MP disease. METHODS: MP bacterial load was measu
A wide spread of existing and emerging battery driven wireless devices do not necessarily demand high data rates. Rather, ultra low power, portability and low cost are the most desired characteristics. Examples of such applications are wireless sensor networks (WSN), body area networks (BAN), and a variety of medical implants and health-care aids. Being small, cheap and low power for the individua
Context: Uncertainty is an unavoidable issue in software engineering and an important area of investigation. This paper studies the impact of uncertainty on total duration (i.e., make-span) for implementing all features in operational release planning. Objective: The uncertainty factors under investigation are: (1) the number of new features arriving during release construction, (2) the estimated
PURPOSE: Patients with primary hyperparathyroidism, pHPT, present with milder symptoms than previously. Some, but not all studies, suggest that this change in clinical pattern also implies lower preoperative parathyroid hormone (PTH) and/or calcium levels and smaller adenomas. This is important since reports indicate that smaller adenomas are more difficult to detect on preoperative imaging, possi
Controlled resistive loads can contribute to damping of electro-mechanical oscillations. This paper presents an on-off damping controller for a single machine system. It was used at a field test in southern Sweden to damp oscillations of a 0.9 MW hydro power generator. The controller used estimated machine frequency as input and controlled a 20 kW resistive load via thyristor switches. The field m

PURPOSE: To identify factors associated with arthroscopically diagnosed scaphoid fracture displacement and instability. METHODS: This was a secondary use of data from 2 prospective cohort studies. The studies included 58 consecutive adult patients with a scaphoid fracture who elected arthroscopy-assisted operative fracture treatment: some for displacement, some as part of a prospective protoco
Aim: Several studies have addressed the association between changes in the female sex hormones estrogen and progesterone levels and changes in parameters of periodontitis. In order to understand how these hormones affect periodontal health it is of major importance to obtain information on their physiological importance. We have previously shown that periodontal ligament cells (PDL cells) express
