In the framework of the semi-hard (k(t)-factorization) approach, we analyze the various charm production processes in the kinematic region covered by the HERA experiments.

We present here a tribute to Per Halldal (February 2, 1922-March 26, 1986), a leader, an instrumentalist, an expert on phototaxis in algae, and one whom we remember, even after 20 years of his death, as a person who spread joy, enthusiasm and knowledge wherever he went.

A new technique to prove convergence of finite difference methods applied to nonlinear PDEs arising in computational fluid dynamics is presented. The underlying systems may be hyperbolic, parabolic or of mixed type like the Navier-Stokes equations. Implicit finite difference methods are analyzed. The essential idea leading to success is the introduction of a pilot function that is highly attractiv

Global change will alter the supply of ecosystem services that are vital for human well-being. To investigate ecosystem service supply during the 21st century, we used a range of ecosystem models and scenarios of climate and land-use change to conduct a Europe-wide assessment. Large changes in climate and land use typically resulted in large changes in ecosystem service supply. Some of these trend

The influence of obesity on the lipolytic capacity of isolated se fat cells was studied prospectively in 13 women and 10 men, all obese, but otherwise healthy, before and 2 and 3 yr after weight reduction by bariatric surgery. Nonobese subjects (25 women and 17 men) without a family history of obesity served as the control group. Lipolytic capacity was determined after stimulation at different ste

Proton induced X-ray emission analysis is useful in measuring changes in particle size distribution of trace elements on exposure of aerosol to the human lung environment and deposition in the air-ways. PIXE analysis is also useful in detecting variations in particle size distributions of elements as they occur in the atmosphere. For the case of lead aerosol along a highway, it is shown that the e

The synthesis and crystal structure of [Co(Hbiim)(2)(H(2)biim)](2)(p-OOCC6H4COOH)(2).H2O (2) is presented. The cobalt(III) complexes are bridged by terephthalates and water molecules, giving a rare, five-fold interpenetrated, net built from 3-connected nodes. The vertex symbol (topology) of this net is determined to 4 122 122, 4 126, 12(4) 12(6) 12(6), or 4 12(2), 4 12(2), 12(3), using the Wellsia

Popular Abstract in Swedish Den fysiska planeringen innebär interaktion mellan aktörer inom skilda samhällssfärer där parter med skilda sociala positioner, resurser, perspektiv och värderingar möts. Aktörernas bilder av vilka effekter ett givet planförslag medför och vilka effekter som ska betraktas som de mest centrala varierar regelmässigt. Mellan de berörda parterna är det därför inte ovanligt Since planning in connection with new building projects frequently generates controversy, it can be seen as a typical form of contentious politics. The aim of this dissertation is to analyze siting controversies, their origin, development and termination, in efforts to explore the problem of legitimacy in planning processes of this sort. The research approach employed is that of a multiple case s

Reflux of equimolecular amounts 2-aminobenzylamine and isatins in acetic acid produced indolo[3,2-c]quinolin-6-ones in good yields. A proposed mechanism involving initial formation of a spiro compound is given. This isolable intermediate subsequently rearranges via a sequential isocyanate ring opening and a cyclisation process to a urea derivative which finally cyclized to the indolo[3,2-c]quinoli

In designing safety-critical real-time distributed control-systems a great potential lies in combining methods within the areas of dependable computer systems and control theory. In this report a brake system on a heavy-duty truck is used as a case study to discuss the choice of distribution level of the computer system and the control algorithms. The distrubution levels of these system aspects ar

Fibroblasts, being one of the resident and structural cells of the lung, have the capacity to produce inflammatory mediators, cytokines and extracellular matrix (ECM) proteins perpetuating the inflammation in the airways of asthmatics. Airway remodeling is also a prominent feature of asthma that affects the lung function causing a thickening of the airways. An increased ECM production of proteogly

Tailbiting trellis representations of linear block codes with an arbitrary sectionalization of the time axis are studied. The notations of regular and irregular tailbiting codes are introduced and their maximal state complexities are lower-bounded. The asymptotic behavior of the derived bound is investigated. Furthermore, for regular tailbiting codes the product state complexity is lower-bounded.

Polyploidy is common in higher plants, and speciation in polyploid complexes is usually the result of reticulate evolution. We examined variation in nuclear AFLP fingerprints, nuclear isozymes, and hypervariable plastid DNA loci to describe speciation patterns and species relationships in the Dactylorhiza incarnatalmaculata polyploid complex (marsh orchids; Orchidaceae) in Greece. Several endemic
