Effect of iodixanol particle size on the mechanical properties of a PMMA based bone cement.

Iodixanol (IDX) is a water soluble opacifier widely used in radiographical examinations of blood vessels and neural tissue, and it has been suggested as a potential contrast media in acrylic bone cement. The effect of the iodixanol particle size on the polymerisation process of the bone cement, the molecular weight, and the quasi-static mechanical properties have been investigated in this article.

Reasoning with Limited Resources: Active Logics Expressed as Labeled Deductive Systems

Reasoning with limited computational resources (such as time or memory) is an important problem, in particular in knowledge-intensive embedded systems. Classical logic is usually considered inappropriate for this purpose as no guarantees regarding deadlines can be made. One of the moreinteresting approaches to address this problem is built around the concept of active logics. Although a step in th

Classification of large pollen datasets using neural networks with application to mapping and modelling pollen data

This thesis concerns the usage of large pollen databases and their application to mapping and modelling past vegetation. Maps of past taxon distributions are generated and classification techniques are used to compile maps of past woodland types. These visualisations of pollen data have applications in forest ecology and in modelling the impacts of climate change. Maps of the distribution limits o

An approach to analog mitigation of RFI

Among all noise sources present in wireline transmission systems we focus on one special type: narrowband radio frequency interference generated by radio amateurs (HAM) and broadcast radio stations. This disturbance, characterized by high power and narrow bandwidth, has the potential of overloading the receiver's analog-to-digital converter (ADC). Once the ADC is in saturation, any countermeasure

Detection of Heart Rate Turbulence Using an Extended IPFM Model

In this study, the IPFM model is extended to account for the presence of ectopic beats and heart rate turbulence (HRT). Based on the model extension, a new approach to characterize HRT is presented based on a set of Karhunen- Loeve (KL) basis functions. The three most significant basis functions possess attractive physiological interpretations which reflect the difference in heart rate prior to th

Legal Ideals and Normative Realities : A case study of children's rights and child labor activity in Paraguay

Popular Abstract in Swedish Denna doktorsavhandling i Rättssociologi handlar om barns rättigheter och barnarbete i Paraguay. Problematiken kring barnarbete i Paraguay är central för avhandlingen och författaren har undersökt samt beskrivit de rättsliga ideal som är tänkta att upprätthålla och stärka det rättsliga skyddet för barns rättigheter. De rättsliga idealen kontrasteras sedemera mot den norThe present study is composed of eight chapters relating to children's rights and child labor activity in the Republic of Paraguay. The problem of child labor in Paraguay is central for this study and the legal ideals that are intended to uphold and strengthen the rights of the child are described and contrasted with the present normative reality in which the children work and live. The discrepanc

Fru Nanna Grönvalls bokbinderi

At the age of 33 and mother of seven children (the husband a shawowy figure), Mrs Grönvall started a small but soon renowed hand book bindery in the town of Malmö in Southern Sweden in 1893. Mostly self-taught herself, through the years she housed and trained several apprentices and journeyman of wich some opened binderies of their own. At the Arts and Crafts Exhibition in Malmö 1907 she was award

Production Control of a Pulp and Paper Mill

A summary of a study devoted to computerized scheduling of a complex integrated pulp and paper mill is presented. A mathematical model of the mill was built and the scheduling problem was formulated as an optimal control problem for a multivariable deterministic system. The mill is described by a linear, first-order, vectorvalued differential equation. The control system consists of 10 state varia

Measurement of dijet cross sections in ep interactions with a leading neutron at HERA

Measurements are reported of the production of dijet events with a leading neutron in ep interactions at HERA. Differential cross sections for photoproduction and deep inelastic scattering are presented as a function of several kinematic variables. Leading order QCD simulation programs are compared with the measurements. Models in which the real or virtual photon interacts with a parton of an exch

Cancer incidence in the Swedish leather tanning industry: updated findings 1958-99.

Abstract in UndeterminedAims: To assess how a 10 year extension of the follow up period affected cancer incidence in the Swedish leather tanning cohort. Methods: A cohort of 2027 tannery workers (of which 482 were women) who had been employed for at least one year between 1900 and 1989 at one of three Swedish leather tanneries, was established. The start of observation varied between 1958 and 1966

Management of gestational diabetes from the patient's perspective - a comparison of Swedish and Middle-Eastern born women.

Aim. To explore patients' evaluation of a specialized diabetes clinic for management of women with gestational diabetes born in Sweden and the Middle East and its contribution to a decreased level of stress and improved coping capability to promote health in patients receiving care. Background. No studies comparing patients' perceptions of healthcare in women of different origin with gestational

Phosphonic Acid Adsorption at the TiO2 anatase (101) surface investigated by periodic hybrid HF-DFT computations

Phosphonic acid (H3PO3) is a candidate as an anchor group that can be used to bind a wide range of molecules to TiO2 surfaces, with practical applications for example in dye-sensitized solar cells. Adsorption geometries and energies of H3PO3 on the TiO2 anatase (1 0 1) surface have therefore been investigated using quantum-chemical periodic hybrid ab initio Hartree Fock density functional theory c
