Coevolutionary interactions are thought to have spurred the evolution of key innovations and driven the diversification of much of life on Earth. However, the genetic and evolutionary basis of the innovations that facilitate such interactions remains poorly understood. We examined the coevolutionary interactions between plants (Brassicales) and butterflies (Pieridae), and uncovered evidence for an

A new subspecies of Anthanassa drusilla, ssp rioverde, is described from Minas Gerais, Southeastern Brazil. This new subspecies is isolated from all odier known subspecies of A. drusilla by at least 2000 km, and its closest taxon based on wing pattern is Anthanassa drusilla higginsi, from Cerro Neblina, Venezuela. To our knowledge, the species is endemic to the region of Pogos de Caldas Plateau (M

The butterfly family Pieridae comprises approximately 1000 described species placed in 85 genera, but the higher classification has not yet been settled. We used molecular data from eight gene regions (one mitochondrial and seven nuclear protein-coding genes) comprising a total of ~6700 bp from 96 taxa to infer a well-supported phylogenetic hypothesis for the family. Based on this hypothesis, we r

This dissertation investigates the use of religious terms and symbols in politics. More specifically, it investigates Muslim politics. Its aim is to analyze the role of religious terms and symbols within a non-fundamentalist political party, namely the Sri Lanka Muslim Congress (SLMC), a Muslim political party that has been part of the democratic process in Sri Lanka since the 1980s. I thereby hop

Organisation är en grundläggande lärobok i organisationsteori. Boken behandlar centrala områden inom organisationsteorin, bland annat arbete, personal, design, teknologi, makt, kultur, identitet och ledarskap. Ämnet ramas in och presenteras i tre delar – Människan, Struktur och Styrning – med begreppet effektivitet som genomgående tema. Boken har tre övergripande syften:1. Att presentera organisat

Capacity development for disaster risk reduction (DRR) has been identified as one of the main ways of substantially reducing disaster losses. In previous research, several elements have been identified that are important in capacity development for DRR. For this study, documentation from nine international capacity development projects for DRR has been analysed. The projects were undertaken by a S

Water vapor diffusion coefficients have been determined with a new set-up of the cup method for mortars with three binders (OPC, OPC + 70% slag, OPC + 10% silica fume) and two water/binder-ratios (0.4, 0.5). The measurements were made as a function of relative humidity with samples on both the absorption and desorption limbs of the sorption isotherm. For OPC samples the results show a clear differ

Fermented oat-based foods offer attractive prospects within the market of non-dairy functional products, since they are suitable substrates for the delivery of probiotic microorganisms, and are significant sources of dietary fiber, both insoluble and soluble such as β-glucan, good quality fat and other phytochemicals important for human health.In the present work, whole oat flour was fermented wit

The structure of interest consists of a nanometer thin copper coating, resting on an infinitely stiff substrate and subjected to nanoindentation by a rigid diamond indenter. The elastic and plastic properties of the coating are investigated for different surface roughening position of attack by the indenter using molecular dynamics. The force-displacement curves, the lattice disorders and the stre

Sewage dilution and formulated fertilization are cost-effective to avoid sewage-deriving phytotoxicity stress and excess fertilizer application in agricultural sewage irrigation practice. However, it is hard for us to fix the parameters of sewage dilution ratio (SDR) and fertilization formula exactly for the best management of sewage irrigation practice according to those published guidelines. Thi

Apple cultivars are attacked by many fungal diseases, both on the tree and during storage. One of the most serious is blue mould, caused by Penicillium expansum. In this study, 5-(n)-alkylresorcinols (AR) were isolated from rye bran by the supercritical fluid of carbon dioxide and were used for the preparation of bioactive emulsions. These emulsions were applied to harvested fruit of five apple va

A method for form finding with dynamic relaxation and Non-Uniform Rational B-Splines (NURBS) based isogeometric membrane elements has been implemented and studied regarding the influence of the discretization and element shape on the form finding. The procedure allows for rapid form finding since NURBS describe the curved geometry well and it is shown that the form-finding can be performed using a

I use Google News to study the relation between news volumes and stock market volatilities. More than nine million stock market-related news stories in English and Chinese are collected and the dynamics of the news volume and the stock market volatility is compared. I find that the stock market volatility and the number of publicly available global news stories are strongly linked in both language
