Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess
There are many different factors that influence our perception of products i.e. personal, product related and external factors. For designers to be able to address them all when creating new products, we need to deepen our understanding of the totality of perceptual experiences from non-instrumental interaction with products. One way of achieving this is by stimulating the creative process by util
Issues with software product quality are commonly reported when organisations engage in outsourcing relationships. To address this issue, value-based software engineering literature emphasises the need for all success-critical stakeholder groups to work towards a mutually agreed goal. Aim: This paper presents a case study that aims to compare and contrast the priority two groups place on software
High resolution transmission electron microscopy and digital image processing has been used to investigate the structure and properties of inorganic materials. The image processing was performed with the programming language Semper. All routines are listed in the appendix. The local order in the disordered mineral blatterite was investigated, and was found to extend over several unit cells. The
In patients with radiculopathy due to degenerative disease in the cervical spine, surgical outcome is still presenting with moderate results. The preoperative investigations consist of clinical investigation, careful history and most often magnetic resonance imaging (MRI) of the cervical spine. When MRI shows multilevel degeneration, different strategies are used for indicating which nerve root/ro
Regioselectivity control was studied in palladium catalysed hydroxycarbonylation of styrene in neat water with water-soluble phosphines, mostly trisulfonated triphenylphosphine, TPPTS, but also N-bis(N', N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylphosphine, N3P. The factor giving the highest changes in regioselectivity in the TPPTS system, under similar reaction conditions, is the temper
BACKGROUND The sperm chromatin structure assay (SCSA) parameter DNA fragmentation index (DFI) has been shown to predict in vivo and in vitro fertility. So far most SCSA studies have been based on SCSA analysis performed on neat semen. The aim of this study is to assess whether SCSA analysis of sperm prepared by density gradient centrifugation (DGC) could add more information in regard to the predi
Implantation of cells genetically modified to express therapeutic genes into the brain has been proposed as a potential treatment for neurodegenerative diseases. In the current study embryonic rat-derived astrocytes were cultured and transduced with a lentiviral vector expressing the reporter gene green fluorescent protein (GFP) and subsequently grafted into the adult rat brain. The proportion of
Silene hifacensis is a narrowly endemic plant, restricted to a few small populations on limestone cliffs in the Spanish province of Alicante and on the Balearic island of Ibiza. The species was collected to extinction in its original mainland location by the early 20th century. Attempts have been made to reintroduce S. hifacensis to this area but conservation efforts are limited by a lack of infor
Occasionally anaesthesiologists find themselves in situations where ventilation during intubation with a fibreoptic bronchoscope (FOB) is desirable. In order to ventilate the patient during the FOB intubation, we used a 90 degree angle swivel connector, normally used for fibreoptic bronchoscopia in an intubated patient. After a nasotracheal tube is placed with the tip in the oropharynx, ventilatio
This study reports on the molecular phylogenetics of ground squirrels, genus Spermophilus, in Turkey using cytochrome b (1140 bp), part of the D-loop and flanking tRNAs (572 bp), X chromosome (867-1051 bp) and Y chromosome (983-989 bp) DNA sequences. Individuals also were characterized by karyotype and with geometric morphometric analyses of mandibles and skulls. Two hundred fourteen individuals f
This study investigates whether intravitreal administration of glial cell line-derived neurotrophic factor (GDNF) enhances survival of NeuN positive retinal cells in a porcine model of retinal ischemia. 16 pigs were subjected to an ischemic insult where intraocular pressure was maintained at 5 mmHg below mean arterial blood pressure for 2 h. The mean IOP during the ischemic insult was 79.5 mmHg (s
Background: Cytokine response is an important factor in the development of shock and organ failure. The aim of this study was to investigate intraperitoneal (peritoneal) and venous (systemic) postoperative cytokine release after major surgery. Methods: Major abdominal surgery was performed in 19 patients. Preoperative systemic measurements and postoperative systemic and peritoneal measurements of
Objective: To evaluate the effects of a single-session, interactive computer-based educational program on knowledge, compliance and quality of life in heart failure patients with special emphasis on gender differences. Methods: One hundred and fifty-four patients, mean age 70 years, from five heart failure clinics were randomised to either receiving only standard education (n = 72) or standard edu
Losses of pelagic diatom production resulting from silica limitation have not only been blamed for toxic algal blooms, but for the reduction in ability of coastal food webs to support higher trophic levels. Recent research has shown the importance of advective seepage water fluxes of dissolved silica (DSi) from freshwater marshes to pelagic waters during moments of riverine Si-limitation. In this
1. We studied the resting metabolic rate (MR) from two great tit Parus major (Linnaeus) populations living in different winter regimes. Birds from the two different localities were exposed individually to +25 °C, 0 °C and −10 °C for the night in three consecutive sessions in random order. 2. Birds from Lund (Sweden) had a lower basal MR, as measured at thermoneutrality (+25 °C), than had birds f
For measuring the physical exposure/workload in studies of work-related musculoskeletal disorders, direct measurements are valuable. However, the between-days and between-subjects variability, as well as the precision of the method per se, are not well known. In a laboratory, six women performed three standardised assembly tasks, all of them repeated on three different days. Triaxial inclinometers
