Stationary and mobile field gamma spectrometry is a useful tool for rapid estimation of environmental radioactivity inventories on and in the ground. A weak point however, is that the depth distribution of the activity in the ground must be known in order to calculate the true activity per unit area or unit mass from an observed photon fluence rate. A promising method for converting incoming spect

The issue of environmental implications of logistics systems is one of the future challenges to logisticians. The purpose of this paper is to explore the logistics and supply chain management discipline to see how the scientific community handles this challenge. Observations in the primary literature revealed that there are weak ties between the logistics/SCM discipline and the environmental disci

Polysulfones carrying benzoyl(difluoromethylenephosphonic acid) side chains were prepared and investigated for use as proton-conducting fuel-cell membranes. In the first step, polysulfones were lithiated and reacted with methyl iodobenzoates to prepare p- and o-iodobenzoyl polysulfones. Next, the phosphonated polysulfones were prepared via CuBr-mediated cross-coupling reactions between the iodinat

This paper presents results from the analysis of the calibration results from the 1997 single burning item (SBI) test round-robin. The influence of the method of determining delay times and response times for the parameters involved in the heat release rate (HRR) calculation, on the overall result of the HRR and the FIre Growth RAte (FIGRA) index is shown. A procedure to determine response times a

Objectives: To review case histories of patients in whom fibrosis played a significant role in the pathogenesis of their disease, and to determine whether intravenous gammaglobulin (IVIg) contributed to the regression of their fibrotic condition. Methods: Eight patients with excess fibrotic reaction in the course of diverse diseases were analysed; a tendency that reverted with different IVIg treat

Popular Abstract in Swedish Den nuvarande teknologin inom förbränningsmotorer har möjligheten att hantera den alltmer strikta myndighetskraven på förbränningsmotorn. Emellertid de nödvändiga tekniska lösningarna som krävs är dyra och alltmer tekniskt krävande. En möjlig väg mot enklare efterbehandlingssystem är anvädningen av Homogen Kompressions Antändning (Eng: HCCI) motor cykeln. Den huvudsaklThe current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. One possible way towards a more simple exhaust aftertreatment system is the use of the Homogeneous Charge Compression Ignition (HCCI) engine cycle. The main advantage o

The size and shape of the cockerel comb, ran be regarded as secondary sexual characters or sexual ornaments. Sexual characters are assumed to be costly to express and the expression of a secondary sexual character is suggested to be favourably correlated with the bearer's condition or fitness. The aim of this study was to clarify the effects of selection for male sexual characters, the correlated

The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics. The thesis include the construction and evaluation of different variable selection te

To increase our knowledge about mating-system evolution, we need to understand the relationship between specific floral traits and mating system. Species of Collinsia (Plantaginaceae) vary extensively in mating system; this variation is associated with variation in floral morphology and development and with the timing of self-pollination. Counterintuitively, large-flowered, more outcrossing specie

Popular Abstract in Swedish There are two major types of diabetes mellitus, Type 1 Diabetes (T1D) and Type 2 Diabetes (T2D), however a number of subtypes have been defined and classified. Maternally Inherited Diabetes and Deafness (MIDD) and Maturity Onset Diabetes of the Young (MODY) are monogenic forms, whereas Latent Autoimmune Diabetes in Adults (LADA) is thought to be a polygenic subtype simiThere are two major types of diabetes mellitus, Type 1 Diabetes (T1D) and Type 2 Diabetes (T2D), however a number of subtypes have been defined and classified. Maternally Inherited Diabetes and Deafness (MIDD) and Maturity Onset Diabetes of the Young (MODY) are monogenic forms, whereas Latent Autoimmune Diabetes in Adults (LADA) is thought to be a polygenic subtype similar to T1D. Mutations in the

The main stimulus for insulin secretion is elevated blood glucose levels. In this thesis the aim was to study less well-known systems involved in the complex regulation of glucose-stimulated insulin release, emphasizing the role of the lysosomal/vacuolar system and the associated glycogenolytic acid alpha-glucoside hydrolases, but also the HO-CO and NOS-NO systems. We performed studies both in hea

Vezdaea rheocarpa is documented for North America for the first time.

We have developed a new reactive force field, ReaxFF, for use in molecular dynamics (MD) simulations to investigate the structures and reactive dynamics of complex metal oxide catalysts. The parameters in ReaxFF are derived directly from QM and have been validated to provide reasonable accuracy for a wide variety of reactions. We report the use of ReaxFF to study the activation and conversion of p

New measurements of radiative lifetimes of four 3d65s levelsin Fe II at about 10 eV are presented along with absolute oscillator strengths for twenty 4p-5s transitions involving the four levels. The experimental measurements are compared with two different sets oftheoretical calculations. The lines are of particular interest in the modeling of HLyalpha pumped fluorescence of Fe II in astrophysical
