Synthesis, Thermal Properties, and Rheological Characteristics of Indole-Based Aromatic Polyesters

Currently, there is an intensive development of bio-based aromatic building blocks to replace fossil-based terephthalates used for poly(ethylene terephthalate) production. Indole is a ubiquitous aromatic unit in nature, which has great potential as a bio-based feedstock for polymers or plastics. In this study, we describe the synthesis and characterization of new indole-based dicarboxylate monomer

Offshore outsourcing : An IT-manager perspective on cultural differences

— Cultural difference is a term often used when discussing problems in offshoring and offshore outsourcing, but only a few authors discuss solutions to bridge pointed out cultural gaps. In this paper earlier research is compared with an IT-manager perspective on experienced cultural differences. Cultural differences were found to include multiple dimensions: cultural distances, cognitive distances

Using metabolite profiling to construct and validate a metabolite risk score for predicting future weight gain

Background Excess weight gain throughout adulthood can lead to adverse clinical outcomes and are influenced by complex factors that are difficult to measure in free-living individuals. Metabolite profiling offers an opportunity to systematically discover new predictors for weight gain that are relatively easy to measure compared to traditional approaches. Methods and results Using baseline metabol

Social context hinders humans but not ravens in a short-term memory task

Using resources shared within a social group – either in a cooperative or a competitive way - requires keeping track of own and others’ actions, which, in turn, requires well-developed short-term memory. Although short-term memory has been tested in social mammal species, little is known about this capacity in highly social birds, such as ravens. We compared ravens (Corvus corax) with humans in sp

Color Sound Symbolism in Natural Languages

This paper investigates the underlying cognitive processes of sound–color associations by connecting perceptual evidence from research on cross-modal correspondences to sound symbolic patterns in the words for colors in natural languages. Building upon earlier perceptual experiments, we hypothesized that sonorous and bright phonemes would be over-represented in the words for bright and saturated c

The typology of sound symbolism : Defining macro-concepts via their semantic and phonetic features

Sound symbolism emerged as a prevalent component in the origin and development of language. However, as previous studies have either been lacking in scope or in phonetic granularity, the present study investigates the phonetic and semantic features involved from a bottom-up perspective. By analyzing the phonemes of 344 near-universal concepts in 245 language families, we establish 125 sound-meanin

Immunological aspects of type 1 and 2 diabetes mellitus.

IDDM occurs predominantly among individuals being class II antigen HLA-DR 3 and/or 4 positive, while NIDDM is not associated with HLA-D. Although the HLA-DR 3 or 4 specificities are prerequisites for IDDM to develop, their high frequencies (about 60%) in the background population preclude tissue typing as a predictive test, underlined by the observation that less than 50% of monozygotic twins are

Perspektiv: Det finns inga genvägar till trygga städer

Beslutsfattare bör alltid vara skeptiska till universallösningar på sociala problem. Detta gäller inte minst BID-modellen, som har kritiserats bland annat för att skapa ett demokratiskt underskott i boendeområden, skriver forskare.

Traffic demand and longer term forecasting from real-time observations

We optimize traffic signal timing sequences for a section of a traffic net-work in order to reduce congestion based on anticipated demand. The system relieson the accuracy of the predicted traffic demand in time and space which is carriedout by a neural network. Specifically, we design, train, and evaluate three differentneural network models and assert their capability to describe demand from tra

Networked authority and regionalised governance : Public transport, a hierarchy of documents and the anti-hierarchy of authorship

This paper is concerned with the authority of written documents and how these artefacts work as governance devices. Networked authority is introduced as a concept to elucidate how documents accumulate formal power in a collaborative process, where several formally independent but informally interdependent organisations together point out the direction of regional public transport planning in the f

Information Processing in the Nervous System. On a Holistic Functional Organization Principle.

This thesis is concerned with the nature of information processing in the nervous system. This issue has been investigated with animal experiments, using male Sprague–Dawley rats, and simulated touch generated by an artificial fingertip with neuromorphic tactile sensors. The processing of the tactile input from the artificial touch system has been analyzed in light of two opposing theories on info
