The background for this master thesis is the stricter emission control requirement in heavyduty diesel engines at the same time as the demands for improved diesel engine efficiency are getting stronger. One approach to meet these demands is to increase the fuel injector pressure. A higher fuel injector pressure makes the fuel spray more finely dispersed into the cylinder and a better combustion is
This master’s thesis examines the norm-critical awareness among children librarians in Swedish public libraries and how the practical everyday work with current literature for children function with this awareness. By adopting a norm-critical approach you have the ability to observe the different types of norms that you can find among us and that effects the way we see the world. Some of these nor
Examining the archaeological material of the modern period, over a period of the last 500 years, this open access book presents a series of case studies that challenges the fallacy of Nordic egalitarianism. The widening gap between rich and poor Western countries is now a well-known phenomenon and, while Scandinavia has often been hailed as one of the regions where inequality has been the lowest,
The objective of this work was to examine the atazanavir-bilirubin relationship using a population-based approach and to assess the possible application of bilirubin as a readily available marker of atazanavir exposure. A model of atazanavir exposure and its concentration-dependent effect on bilirubin levels was developed based on 200 atazanavir and 361 bilirubin samples from 82 patients receiving
We present Ar-40/Ar-39 data acquired by infra-red (CO2) laser step-heating of alunite crystals from the large Miocene Colquijirca district in central Peru. Combined with previously published data, our results show that a long (at least 1.3 My) and complex period of magmatic-hydrothermal activity associated with epithermal Au-(Ag) mineralization and base metal, Cordilleran ores took place at Colqui
Throughout the Northern Hemisphere, changes in local and regional climate conditions are coupled to the recurring and persistent large-scale patterns of pressure and circulation anomalies spanning vast geographical areas, the so-called teleconnection patterns. Indeed, the atmospheric fluctuations described by the North Atlantic Oscillation (NAO) are closely associated with the last four decades of
Isomeric states in the semimagic Sn128-130 isotopes were populated in the fragmentation of a Xe-136 beam on a Be-9 target at an energy of 750 A.MeV. The decay of an isomeric state in Sn-128 at an excitation energy of 4098 keV has been observed. Its half live has been determined to be T-1/2 = 220(30) ns from the time distributions of the delayed gamma rays emitted in its decay. gamma gamma coincide
A method for determination of the accessible volume fraction in gels as function of the molecular weight of the solutes is presented. The pore-size distribution is determined by measuring the rate of diffusion of a mixture of solutes into a gel using gel filtration for separation. The solutes, of various sizes, are detected by refractive index measurements. Two marker molecules (blue dextran and g
This cross-sectional study was done in order to ascertain whether there is a lifelong beneficial effect on bone mineral density (BMD) of early, long-lasting, and intense physical exercise. Forty-eight male ex-weight lifters, mean age 64 years (range 50-79) participated. They had followed a training program of an average of 10 hours/week (range 4-20) for an average of 13 years (range 1-34). They ha
To elucidate how diabetic patients with limb-threatening foot lesions perceive and evaluate content and organisation of treatment in a multi-place hyperbaric oxygen chamber. To our knowledge there are no patients' evaluations of diabetes care in a high-technology area like the hyperbaric oxygen chamber. The burden on persons with diabetic foot complications might be increased if adjuvant therapy w
From the half-angle substitution of trigonometric terms in the Ernst equation, rational approximations of the flip angle dependence of the FLASH signal can be derived. Even the rational function of the lowest order was in good agreement with the experiment for flip angles up to 20°. Three-dimensional maps of the signal amplitude and longitudinal relaxation rates in human brain were obtained from e
Nanowires in the InAs/InP material system are grown with catalyst-assisted chemical beam epitaxy. Ohmic contacts are then fabricated to selected wires, allowing electron transport measurements to be carried out at room-temperature as well as at low T. InAs nanowires show strong quantum confinement effects, where thin wires (<30nm) are depleted from carriers. Measurements on InAs wires with a quant
The purpose of this study was to investigate the influence of selective denervation of the rat pancreas on hormone secretion and on peripheral insulin sensitivity. Thirteen rats, 7 denervated and 6 sham operated, received an intravenous glucose challenge for 30 min. The basal plasma levels of insulin, glucagon and glucose did not differ between the two groups. An augmented insulin response to gluc
The purpose of this study was to investigate the early alterations of retinal function, assessed with electrophysiology, in newly onset type 2 diabetes patients without vascular retinopathy. Seventeen patients with newly diagnosed type 2 diabetes (duration 7 ± 3 months), without any vascular retinopathy in fundus photographs, were examined with full-field electroretinogram (ERG) and multifocal ERG
Popular Abstract in Swedish Nuförtiden är det tryckta bokomslaget en självklar del av boken som produkt och konsumentvara. I avhandlingen studeras etableringen av bokomslaget och dess betydelse för omstruktureringen av bokmarknaden i Sverige decennierna kring 1800. Från mitten av 1700-talet blev den färdigbundna boken en betydelsefull del av bokhandelns utbud. Förlag och bokhandel började sälja deThe aim of the dissertation is to examine the significance of the paperbound book on the book market as part of the history of consumption. It is an examination of the materiality of the book, in which the form and function, economics and distribution of the binding during the last century of the hand-press era are studied. The intention has been to show that the ready-bound book was a means for t
In old mnemonic systems, like the Memory Palaces (Ricci) and the Memory Circles (Llull), the general purpose is to organize and preserve the images of memory over time. However, in contemporary discussions of memory taking place within the field of trauma studies (Leys, Laub, Feldman, Caruth, van der Kolk), the focus is on the forgotten, and on understanding why we do not remember traumatic events
Although Singapore, a linguistically and ethnically diverse city–state, uses four official languages, namely Malay, Mandarin, Tamil, and English, which are supposed to enjoy equal status, there appears to be a pecking order to these languages. English seems to be the dominant language when taking into consideration the bilingual education policy, numerous campaigns promoting its use in terms of sp
Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS experiment at the LHC. Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector will receive damage from non-ionizing radiation in excess of 1015 1 MeV neq/cm2, while the pixel detector designed
