Popular Abstract in Swedish Avhandlingen behandlar nätverksmekanisk modellering av mekaniska egenskaper hos cellulosafiberfluff. Cellulosafiberfluff består av fibrer utvunna från trä, och används bl a i blöjor och isoleringsmaterial. En nätverksmekanisk modell är en typ av mikro-mekanisk modell. Principen för denna typ av modell är att man gör antaganden för hur materialet fungerar på mikro-nivåA network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. Model networks composed of bonded fibres of arbitrary distribution in length, curvature, cross-section, stiffness and strength were inves

Three amperometric enzyme electrodes have been constructed by adsorbing anionic royal palm tree peroxidase (RPTP), anionic sweet potato peroxidase (SPP), or cationic horseradish peroxidase (HRP-C) on spectroscopic graphite electrodes. The resulting H2O2-sensitive biosensors were characterized both in a flow injection system and in batch mode to evaluate their main bioelectrochemical parameters, su

A compact six-figure approximation formula for the inductance of a cylindrical current sheet is presented. The formula displays the correct asymptotic behavior in the respective cases of very long and very short coils. The efficiency of the approximation formula is due to a thorough analysis of the exact formula.

The spectroscopic data mercury (Hg) I and Hg II was analyzed from beam-foil spectroscopy. The wavelength was found to be of course fixed and independent of the light source and recording conditions. It was found that if the calculated branching ratio was correct, then the Hg II was an important constituent of fluorescent light tube plasmas. The wavelength region from 40 to 600 nm in overlapping wa

Antibodies are critical entities used for the protection of an individual organism against infection and disease. Through a complex series of events genes rearrange to encode repertoires of molecules, which are tested for their ability to identify foreign molecules. In this report, we discuss factors defined by the individual as well as by infectious organisms that shape the antibody repertoire. A

High-spin states in the odd-odd N=Z nucleus Rb-74(37)37 were studied using the Ca-40(Ca-40,alphanp) reaction. A previously observed odd-spin T=0 band has been extended to I-pi=(31(+)) and an even-spin T=0 band has been observed for the first time to I-pi=(22(+)); both have a pi(g(9/2))circle timesnu(g(9/2)) structure. A strongly coupled low-spin T=0,K=3 band has been interpreted as being based upo

System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. System Dynamics is the use of the results of System Analysis in order to reconstruct the system of causalities. Modelling is used for understanding comp

A new method of correction of instrumental shifts and gain changes observed in experimental spectra is presented. An application of the method to the data collected in a large scale in-beam gamma-ray spectroscopy experiment is discussed.

A class of spherical functions is studied which can be viewed as the matrix generalization of Bessel functions. We derive a recursive structure for these functions. We show that they are only special cases of more general radial functions which also have a properly generalized, recursive structure. Some explicit results are worked out. For the first time, we identify a subclass of such radial func

A promising technique for dating paleosols is reported based on radiocarbon (C-14) dating of asexual spores from vesicular-arbuscular mycorrizae (VAM). The soils are dispersed in water and some 6000-8000 spores separated by hand picking under a low power microscope. The dried spores are then dated by accelerator mass spectroscopy (AMS). A chronosequense of closely superimposed paleosols from an ar

There is a need for mathematical modelling for the evaluation of important parameters for photon imaging systems. A Monte Carlo program which simulates medical imaging nuclear detectors has been developed. Different materials can be chosen for the detector, a cover and a phantom. Cylindrical, spherical, rectangular and more complex phantom and source shapes can be simulated. Photoelectric, incoher

This work concentrates on automatic procedures for simplifying chemical models for realistic fuels using skeletal mechanism construction and Quasi Steady-State Approximation (QSSA) applied to detailed reaction mechanisms. To automate the selection of species for removal or approximation, different indices for species ranking have thus been proposed. Reaction flow rates are combined with sensitivit

This report investigates how determination of safety distances during urbanisation in the proximity of major industrial hazards occurs as well as the factors and aspects that should be considered when doing so. An interview-study is carried out with relevant stakeholders with the following results being highlighted by the interviewees: - Today determination of safety distances are made by municipa

Vulvar pain has been known of for thousands of years but the general knowledge of vulvar pain is limited and the condition receives less medical attention than other disorders. Previous research focus on physical and/or psychological causes, treatment strategies and problematizing female sexuality due to women’s inability to engage in sexual intercourse. This master thesis attempt to understand v

Syftet med uppsatsen är definiera och försöka förstå hedersrelaterat våld. Frågorna som ställs är: Vad är heder och vad spelar heder för roll i våldsproblematiken? Vilka olika typer av våld utsätts man för i en hederskultur? Hur uppnås hedersideologins mål och syfte med hjälp av våld? Hur kan man se hedersrelaterat våld utifrån en helhet och inte bara utifrån det sensationella, dödliga våldet The purpose of this paper is to define and understand honour-related violence. These are the questions asked for this purpose: What is honour and what role does honour play in making meaning of violence? What are the different types of violence someone is subjected to in a culture of honour? How does the ideology of honour achieve its goals and objectives through violence? How can one see hono
