Platelet activating factor (PAF) has been reported to produce a variety of airway effects including epithelial damage and increased airway-lung absorption of hydrophilic tracers. The present study examines effects of PAF on the guinea-pig tracheobronchial mucosa in vivo. Vehicle with and without PAF (4.0 and 8.0 nmol) was superfused onto the tracheobronchial mucosa. The levels of 125I-albumin, pre
Studien analyserar möjligheterna att reducera energianvändning och emissioner från den svenska transportsektorn fram till år 2015. Energianvändning och emissioner beräknas utifrån officiella prognoser om transportarbetets utveckling samt uppskattningar av specifik energianvändning och emissionsfaktorer för olika teknologi- och bränsleval och transportslag. Emissionerna jämförs med såväl officiell
The new paramyxean Paramyxoides nephtys gen. n., sp. n. is described based on cytological characters. The organism reproduces by endogenous budding, and sporogony is the only sequence of reproduction observed. A primary cell with narrow haplosporosomes gives rise to two or four secondary cells (sporonts), each yielding four tetracellular spores in which the cells are situated one within the other.
Rapport från en internationell konferens i Montreal 11-13 oktober 1998 "The First International Conference on New Information Technologies for Decision Making in Civil Engineering". Författaren (som är bibliotekarie) var den enda representanten från Sverige bland ca 280 forskare från 26 länder, och berättar om sitt eget bidrag: "CER: A Handy Tool for the Civil Engineer", men tar även hjälp av 5 ol
The incidence of Diabetes Mellitus increases globally in epidemic proportions. Type 2 Diabetes is the most prevalent form of Diabetes, comprising 90% of the patients. In Type 2 Diabetes, two processes contribute to the development of the disease: insufficient insulin secretion from the pancreatic ?-cell and insulin resistance of the target organs. This leads to loss of control of blood glucose lev
A new reduced-complexity Schnorr-Euchner decoding algorithm is proposed in this letter for uncoded multi-input multi-output systems, with q-QAM (q = 4, 16....) modulation. Furthermore, a Fano-like metric bias is introduced to the algorithm from the perspective of sequential decoding, as well as an early termination technique. Simulation results show that these modifications reduce the algorithm co
Repeated exposures to both microbial and innocuous Ags in vivo have been reported to both eliminate and tolerize T cells after their initial activation and expansion. The remaining tolerant T cells have been shown to suppress the response of naive T cells in vitro. This feature is reminiscent of natural CD4+CD25+ regulatory T cells. However, it is not known whether the regulatory function of in vi

This dissertation addresses the question of what the function of morphological case is in Icelandic. The working hypotheses of this book is that morphological case is a multifunctional category. Firstly, new verbs in Icelandic were collected and examined to cast light on the productivity of the morphological cases, revealing that not only are the nominative and accusative productive in Icelandic b
Background: Flat and depressed colorectal tumours are common in Japan but are very rare or non-existent in Western countries. Aims: To study the occurrence of flat colorectal tumours in a southern Swedish population. Methods: In this prospective study, 371 consecutive European patients were examined by high resolution video colonoscopy combined with chromoendoscopy. The nature of the lesions was
Popular Abstract in Swedish Fraktal teori applicerad på regn.Fractal theory involving scaling properties has been applied in a wide range of research areas, particularly within natural sciences. In the present thesis, fractal theory has been applied to the rainfall process. The main questions to be answered were: (1) is rainfall characterized by scaling and fractal properties, and, if so, (2) how can these properties be modeled and used in applied hydrology
The max-bisection problem is to find a partition of the vertices of a graph into two equal size subsets that maximizes the number of edges with endpoints in both subsets. We obtain new improved approximation ratios for the max-bisection problem on the low degree k-regular graphs for 3 less than or equal to k less than or equal to 8, by deriving some improved transformations from a maximum cut into
High-speed laser diagnostics was utilized for singlecycle resolved studies of the formaldehyde distribution in the combustion chamber of an HCCI engine. A multi- YAG laser system consisting of four individual Qswitched, flash lamp-pumped Nd:YAG lasers has previously been developed in order to obtain laser pulses at 355 nm suitable for performing LIF measurements of the formaldehyde molecule. Burst
Three experiments were conducted to investigate the impact of affect on moral judgment. Participants read stories describing morally questionable actions and made judgments of wrongness. Judgments were affected by morally irrelevant disgust, and the effect was moderated by individual differences in disgust sensitivity and preferred processing mode. More specifically, the effect was stronger for pa
One of the main problems in using parabolic concentrators with standard photovoltaics (PV) cells is the highly non-uniform illumination of the cells. The non-uniform irradiation causes high resistive losses in the standard cells due to their relatively high series resistance. This results in a considerably lowered efficiency. To solve the problem, we introduce three different structured reflectors
