Accurate description of the response function of X-ray detectors is important for quantitative PIXE analysis. For analytical description of low-energy tailing in PIXE spectra, the GUPIX approach was used, i.e. a combination of Hypermate type functions. The low-energy tailing parameters of a low-energy high purity germanium X-ray detector in the region 1.3-9.2 keV was determined by systematic fitti
Object: The aim of the present study was to investigate the pattern of non-fatal heroin overdoses for men and women in Sweden, a country with late onset of heroin use. Material: Subjects were recruited through the Syringe Programme and the Addiction Centre in Malmoe. A total of 149 subjects were interviewed, 108 men and 41 women. They were asked about their social situation, experienced and obser
Several recent international publications (e.g. Platzack 1996, 2001; Håkansson, Pienemann & Sayehli 2002; Pienemann 1998; Pienemann & Håkansson 1999) have claimed that learners take the same developmental route in the acquisition of syntax of a second or foreign language, irrespective of their first language (L1). Targetlike verb placement in a Germanic V2 language like German, Dutch or Sw
Transverse relaxation dispersion NMR spectroscopy can provide atom-specific information about time scales, populations, and the extent of structural reorganization in proteins under equilibrium conditions. A method is described that uses side-chain methyl groups as local reporters for conformational transitions taking place in the microsecond regime. The experiment measures carbon nuclear spin rel
The effect of ultraviolet radiation (UV) (255-325 nm) on stomatal closure was investigated on tef (Eragrostis tef (Zucc) Trotter) in the presence of white light (ca 50 .mu.mol m-2 s-1). The action spectrum showed that UV (ca 2 .mu.mol m-2 s-1, half band width about 10 nm) of 285 nm or shorter wavelengths was very efficient in causing stomatal closure. The effectiveness decreased sharply towards lo
Research within nursing and medicine is moving at an increasing pace. This makes it difficult for the staff - involved with medical care to find the right path through all the new research and development. Working according to evidencebased procedures within both medicine and nursing means using in one’s work the recommendations which have been based on literature studies that have compiled, revie
Abstract in UndeterminedWithin cognitive linguistics, there is an increasing awareness that the study of linguistic phenomena needs to be grounded in usage. Ideally, research in cognitive linguistics should be based on authentic language use, its results should be replicable, and its claims falsifiable. Consequently, more and more studies now turn to corpora as a source of data. While corpus-based
This paper evaluates the hardware aspects of multicarrier faster-than-Nyquist (FTN) signaling transceivers. The choice of time-frequency spacing of the symbols in an FTN system for improved bandwidth efficiency is targeted towards efficient hardware implementation. This work proposes a hardware architecture for the realization of iterative decoding of FTN multicarrier modulated signals. Compatibil
This paper presents an exploration framework which performs data assignment and access scheduling exploration for applications given a multilayer memory architecture. Our framework uses multiobjective criteria during exploration, such as application execution time, energy, bandwidth, and data size. In order to tackle the complexity of the exploration, it is divided into three phases; Pareto diagra
Abstract in UndeterminedA new phantom has been designed that can provide simultaneously different target to background activity ratios with a linearly changing diameter of lesions. The purpose of the study was to describe and perform initial measurements with the phantom aimed to characterize different nuclear medicine tomographic systems and reconstruction algorithms in their performance and beha
The assembly of data from different parts of proteomics workflow is often a major bottleneck in proteomics. Furthermore, there is an increasing demand for the publication of details about protein identifications due to the problems with false-positive and false-negative identifications. In this report, we describe how the open-source Proteios software has been expanded to automate the assembly of
