As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. Ultrasonic Doppler is a frequently used technique in non-invasive hemodynamic studies. To increase the a
Intim a-media thickness (IMT) is considered as a valuable marker of early atherosclerosis. We suggest a new algorithm for simultaneous measurements of absolute diameter at diastole, distension (diameter change), IMT at diastole and the intima-media compression (IMC) with a new fast, robust, high-resolution, and automatic algorithm utilizing the ultrasonic gray-scale information. The new algorithm
The quality of a product can be defined by its ability to satisfy the needs and expectations of its customers. Achieving quality is especially difficult in market-driven situations since the product is released on an open market with numerous potential customers and users with various wishes. The quality of the software product is to a large extent determined by the quality of the requirements eng
A simple method is described for a rough classification of soil bacterial populations. The method makes use of a commercially available biochemical test system and the test results are analysed in a multivariate classification program on a microcomputer. The method was used for classification of bacteria from rape rhizosphere.
The level of administered activity in radionuclide therapy is often limited by haematological toxicity resulting from the absorbed dose delivered to the bone marrow. The purpose of these EANM guidelines is to provide advice to scientists and clinicians on data acquisition and data analysis related to bone-marrow and whole-body dosimetry. The guidelines are divided into sections "Data acquisition"
Protein adsorption is a complex process that it controlled by several different mechanisms, for example: (i) electrostatic interactions between the protein and the surface, and (ii) between adsorbed proteins; (iii) dispersion interactions; (iv) hydration effects; and (v) structural rearrangements of the protein to balance conformational chain entropy with energetics. The aim of this study was to d
OBJECTIVE: To compare robot-assisted laparoscopy and laparotomy for radical hysterectomy and pelvic lymphadenectomy in terms of hospital costs. METHODS: Consecutive women undergoing radical hysterectomy and pelvic lymphadenectomy as a sole procedure between January 2001 and February 2012 were included. We compared OR times, hospital stay, procedure specific costs, blood transfusions and cost for r
Slepian models are derived for a stochastic process observed at level crossings of a moving average driven by a gaussian or Laplace noise. In particular, a Slepian model for the noise – the Slepian noise – is developed. For Laplace moving average process a method of sampling from the Slepian noise is also obtained by a Gibbs sampler. This facilitates comparison of behavior at crossing of a level b
Ultraviolet radiation (UVR) exposure is the main risk factor for cutaneous malignant melanoma (CMM), but its specific effect in infancy is unknown. We examined whether season of birth, a proxy for solar UVR exposure in the first few months of life, is associated with CMM in childhood through young adulthood.
Background: Activity performance is marked by the degenerative nature of Parkinson's disease (PD), but few qualitative studies have focused on how people with PD perceive participation in life situations. Objective: To identify and describe barriers and facilitators for participation from the perspective of people with PD. Methods: Qualitative data was obtained by the focus group method using a se
Increased recirculation of process water has given rise to problems with formation of calcium oxalate incrusts (scaling) in the pulp and paper industry and in forest biorefineries. The potential in using oxalate decarboxylase from Aspergillus niger for oxalic acid removal in industrial bleaching plant filtrates containing oxalic acid was examined and compared with barley oxalate oxidase. Ten diffe
We describe a series of microcalorimeter X-ray spectrometers designed for a broad suite of measurement applications. The chief advantage of this type of spectrometer is that it can be orders of magnitude more efficient at collecting X-rays than more traditional high-resolution spectrometers that rely on wavelength-dispersive techniques. This advantage is most useful in applications that are tradit
Hydro-hegemonic praxis defines much of Israel’s occupation that has continued since the signing of the Oslo Accords in 1993. Two empirical case studies of hydro-hegemony and counter-hegemony at local level are compared in this paper: the Israeli-occupied Golan Heights and the Israeli-occupied West Bank. Both case studies show that control over water resources and supply provides political power ov
Recent advancements in almost all aspects of hemophilia treatment have vastly improved patient care and management, and new and emerging treatments hold the promise of further progress. However, there remains a scarcity of data on long-term outcomes in hemophilia, particularly among those patients with inhibitors, for whom no validated outcome assessment tools are currently available. At the 15th
Over the past three decades, a range of attempts have been made to raise the importance of science, technology and innovation on the policy agenda in Africa. This article explores four themes along which growth paths and patterns may be realized, namely regional and global integration, inclusive innovation, priorities and approaches to diversify African economies, and the role of the state. The ou
