Age-determinations on a complex array of mafic dykes across the eastern Kaapvaal craton (Olsson et al.. 2010) are complemented herein by field evidence, dyke trend analysis, and petrological characterization of 58 dyke samples. similar to 2.95 Ga SE-trending, a similar to 2.65 Ga E- to SE-radiating, and similar to 1.90 Ga NE-trending swarms can be distinguished. Prominent Archean (similar to 2.95
Energy efficiency ex-ante policy evaluation is commonly, but not exclusively, concerned with the simulation and modelling of policy instruments and resulting technological change. Using the residential sector as case study, the paper provides a meta-analysis of models and modelling exercises and scrutinise their relevance for the field of energy efficiency policy evaluation. The methodology of stu
High resolution real time heat release analysis will become increasingly important in the future development of engine control systems. The increased demands on efficiency and emissions will put high demands on future engine control. Future engine concepts, for example the HCCI engine concept might crave cylinder pressure based Closed-Loop Combustion Control (CLCC). The analysis of cylinder pressu
Popular Abstract in Swedish I den litteratur om marknadsföring, som vanligen används på universitet och högskolor, framställs ofta marknadsföringsarbete som något som äger rum i en objektivt given värld, vilken kan observeras, diskuteras och studeras som ett ”faktum” utanför och mer eller mindre oberoende av företaget och dess aktiviteter. I denna avhandling är utgångspunkten istället att det vi uThe aim of this thesis is to offer a contribution to the understanding of marketing work. In orthodox, mainstream marketing management literature, the work of marketing is commonly depicted as a fairly straightforward practice, technical in character, neutral in terms of social values and ideologies, operating within an objective and pre-given world. A counter picture to this idealised view of mar
The morphological matrix is an important element of the engineering design methodology and is present in many textbooks. This method originally aimed at generating an exhaustive set of solutions for a given problem, by decomposing it into subproblems, finding solutions to each subproblem, and combining them. One issue associated with the morphological matrix has been the necessity to deal with the
Customers of the packaging material industry are demanding shorter and more customized orders for each year. In many cases, the production has adapted to the new market demands. However, some finished goods warehouses are still adapted to the larger order sizes following a build-to-stock policy. In finished goods warehouses a shorter order sizes create problems, such as an increased amount of hand
We study deterministic algorithms for the gossiping problem in ad hoc radio networks under the assumption that each combined message contains at most b(n) single messages or bits of auxiliary information, where b is an integer function and n is the number of nodes in the network. We term such a restricted gossiping problem b(n) -gossiping. We show that rootn-gossiping in an ad hoc radio network on
Aim: To update the first version of the European core curriculum to reflect many developments in radiotherapy and educational philosophy that have taken place in the interim period. Materials and methods: The first version of the European core curriculum was reviewed by the Steering Group together with current education programmes from the various member states and taking into account the developm
Methane production from llama and cow manures from the Bolivian high plateau (The "Altiplano") was studied using a parallel reactor set-up consisting of 10 lab-scale biogasifiers. The effects of pressure (495 and 760 mmHg), temperature (11 and 35 degrees C), hydraulic retention time (20 and 50 days), and manure content in the slurry (10%, 20% and 50%) were evaluated with respect to productivity an
OBJECTIVE: In acute respiratory distress syndrome, the relationships between changes in the elastic behavior of the respiratory system and biological markers of extra-cellular matrix or surfactant turn-over could give some insights into its pathophysiological determinants. DESIGN AND MEASUREMENTS: In 17 patients with acute respiratory distress syndrome, we assessed the relationship between chord c
Background: The Lundby Study is a prospective, longitudinal study on a total population consisting of 3563 subjects during 50 years. This study compares first incidence rates of depression and cumulative probabilities for developing a depression over the two time periods 1947-1972 and 1972-1997. Method: The Lundby Study started in 1947. Follow-ups were carried out in 1957 and in 1972. In 1997 the
Hollow fibre (HF) membrane modules were applied in continuous mode for equilibrium sampling through membranes (ESTM) of polar organic pollutants. Phenolic compounds (chlorophenols, cresols and phenol) served as model substances and ESTM was tuned towards the measurement of freely dissolved concentrations (C(free)). HF membrane modules were constructed using thin-walled membrane, 1-m module length
Basic neurotransplantation research evoked clinical trials of restorative brain surgery. Parkinson's disease was the first and primary test bed for this putative new therapeutic method. Various centers performed the grafting surgery and the behavioral evaluations in different ways, and observed a varying degree of symptomatic relief. This led to a plea for double blind placebo-controlled clinical
Drying is one of the most energy intensive and common operations in the chemical and process industries. Scope for energy recovery is substantial, particularly from the latent heat of the exhaust moist air. Using real operating data from a major Swedish mill, optimal energy conservation strategies were investigated using different heat pump systems in paper drying. Simulation results are compared
To optimize treatment of chronic hepatitis C early identification of patients who will not achieve a sustained virological response (SVR) is desirable. We investigated hepatitis C virus (HCV) RNA kinetics at day 1 (in 15 patients; genotypes 1 and non-1, 9 and 6 respectively) at weeks 1, 4 and 12 (in 53 patients; genotypes 1 and non-1, 19 and 34, respectively) during treatment with pegylated interf
