Individual-based modelling is a promising tool for scaling from the individual to the population and community levels that allows a wide range of applied and theoretical approaches. Here, we explore how intra-specific competition affects population dynamics using FORSITE, an individual-based model describing tree-tree interactions in a spatial and stochastic context. We first describe FORSITE desi
Betony, Betonica officinalis L., is one ofthe rarest plants in Scandinavia and has the longestdocumented history. It was reported at the parish ofStehag in Skåne, southernmost Sweden, by the Danishhumanist and publisher Christiern Pedersen asearly as 1534, one of the world’s oldest records wherea species is tied to a specific locality. Literature andcollections testify that Betony was commoner in
The increasing importance being placed on waste prevention in Swedish wastegovernance raises the question of how waste prevention is defined in practice.This paper presents a qualitative analysis of a sample of fifty-one key Swedishwaste prevention initiatives with the purpose of identifying which kind ofactions are imagined, promoted, and set into motion under the label of wasteprevention. The an
The photon-induced Auger and photoelectron spectra of the argonlike ions Cl- (in NaCl), K+ (in KCl), Ca2+ (in CaCl2 and CaF2), and Sc3+ (in Sc2O3) have been measured in the vicinity of the L23 absorption edges of these ions. It is shown that at the 2p6→2p53d(4s) resonance a spectator structure appears in the L23M23M23 Auger spectra, which shifts to higher kinetic energies with increasing photon en
This paper adds to the relatively few European studies on the pedestrian friendliness of urban areas, and on transport walking. Using the Human Environment Interaction (HEI) model (Küller, 1991), the study explores the associations between perceived neighbourhood spatialphysical and social environment qualities and walking to neighbourhood destinations, and examines whether these associations are
Defects in ribosome biogenesis and function are present in a growing list of human syndromes associated with cancer susceptibility. One example is X-linked dyskeratosis congenita (X-DC) in which the DKC1 gene, encoding for an enzyme that modifies ribosomal RNA, is found to be mutated. How ribosome dysfunction leads to cancer remains poorly understood. A critical cellular response that counteracts
Crystalline Cs2KMnF6, when prepared below 500°C, adopts a tetragonal elpasolite structure type. Differential scanning calorimetric investigations indicated that Cs2KMnF6 undergoes a phase transition from the low-temperature tetragonal phase (LT) to a high-temperature phase (HT) at about 530°C. Single crystals of the new HT phase could be obtained by annealing a crystalline LT specimen at 600°C fol
Proteoglycan monomer and link protein isolated from the Swarm rat chondrosarcoma both contain glycosylamine-linked oligosaccharides. In monomer, these N-linked oligosaccharides are concentrated in a region of the protein core which interacts specifically with both hyaluronate and link protein to form proteoglycan aggregates present in the cartilage matrix. Chondrocyte cultures were treated with tu
Implantation of demineralized bone matrix in rodents elicits a series of cellular events leading to the formation of new bone inside and adjacent to the implant. This process is believed to be initiated by an inductive protein present in bone matrix, and local growth factors may further regulate the process. We have previously shown that local application of recombinant human basic fibroblast grow
Objective-To examine if unilateral knee injury affects the synovial fluid concentrations of aggrecan fragments, cartilage oligomeric matrix protein (COMP) fragments, stromelysin-l, and tissue inhibitor of metalloproteinases-l (TIMP-1) in the contralateral uninjured knee. Methods-Synovial fluids from the injured and uninjured knees were obtained at different times in a group of patients after unila
We have previously shown synovial fluid (SF) proteoglycan concentrations to be sensitive markers of altered cartilage metabolism in arthritis. We determined the proteoglycan concentrations in sera and SF from 23 patients with juvenile chronic arthritis and in sera from 30 healthy children by a specific enzyme linked immunosorbent assay. In both groups of children, decreasing concentrations of prot
Modeling of the supercritical fluid extraction of solid materials is an important aspect in order to understand and predict the process. A comparison of two empirical models, two semi-empirical models and two mechanistic models is performed using calibration of single experiments. It is concluded that the best fit is obtained using a simple empirical expression. Furthermore, single calibrations di
Breathing pattern as periodic breathing (PB) in chronic heart failure (CHF) is associated with poor prognosis and high mortality risk. This work investigates the significance of a number of time domain parameters for characterizing respiratory flow cycle morphology in patients with CHF. Thus, our primary goal is to detect PB pattern and identify patients at higher risk. In addition, differences in
This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. At high load the exhaust heat was increased more than at high engine speed. Swir
Urban theory has historically situated ethnic commercial strips as an organic extension of nearby ethnic residential enclaving. While this is still a useful way to frame such commercial spaces in many cities, this article argues that some areas of this sort function as a marketable branding mechanism (intended or not) to produce nearby residential gentrification. This article explores the influenc
In the scope of a Swedish research project on expert knowledge as a basis for legal decisions, this article focuses on serious criminal cases. Using a model that describes rhetorical situations as well as empirical material based in 150 court decisions, the aim is to analyze the conditions surrounding the use of expert evidence in criminal law processes, to what extent and by whom such evidence is
Miljontals människor världen över arbetar som gatuförsäljare, utom räckhåll för lagen. Eftersom verksamheten ses som illegal lever försäljarna under ett ständigt hot om att avhysas och att få sina varor konfiskerad. Olika strategier för formalisering, det vill säga stegvis legalisering, förespråkas och tillämpas, av såväl internationella utvecklingsorganisationer som regeringar, för att stärka gatMillions of people worldwide work outside the law as street vendors in order to earn a living. However, they often work in fear of police evictions and confiscations since their work is in many places considered illegal. In this context, formalization (steps towards legalization) is often portrayed as a model for empowerment that allows poor street vendors to improve their well-being. Formalizatio
Much has been written on the distinction between vertical and horizontal foreign direct investment. However, most of the empirical literature relies on indirect and aggregated measures only. The aim of this paper is to help fill this gap by examining the differences between German affiliates in the Czech Republic and their mother companies in Germany on the basis of direct evidence on factor requi
