Distinct roles of light-activated channels TRP and TRPL in photoreceptors of periplaneta americana

Electrophysiological studies in Drosophila melanogaster and Periplaneta americana have found that the receptor current in their microvillar photoreceptors is generated by two light-activated cationic channels, TRP (transient receptor potential) and TRPL (TRP-like), each having distinct properties. However, the relative contribution of the two channel types to sensory information coding by photorec

Can a teachable agent influence how students respond to competition in an educational game?

Learning in educational games is often associated with some form of competition. We investigated how students responded to winning or losing in an educational math game, with respect to playing with or without a Teachable Agent (TA). Students could choose between game modes in which the TA took a more passive or active role, or let the TA play a game entirely on its own. Based on the data logs fro

Implicit les applied to isothermal swirling coaxial jets

This work is devoted to the analysis of the interaction of two coaxial jet with swirling flow using Large Eddy Simulation methodology to reproduce the case of Roback and Johnson. The eight - flat - vanes in the annular nozzle are the precursor of the swirling annular jet with high swirl number. An implicit LES model was used, this model uses mesh size as filter width so no sub-grid model is requir

Structural transformation and agrarian change in India

The landlord and his emaciated labourer are symbolic of Indian agriculture. However, this relationship is less assured as large landowners have fallen from their superior position. This volume explores how this emblematic pair is becoming a thing of the past. Structural Transformation and Agrarian Change in India investigates whether family labour farms are gaining prominence as a consequence of t

Interspecific variation in the relationship between clutch size, laying date and intensity of urbanization in four species of hole-nesting birds

The increase in size of human populations in urban and agricultural areas has resulted in considerable habitat conversion globally. Such anthropogenic areas have specific environmental characteristics, which influence the physiology, life history, and population dynamics of plants and animals. For example, the date of bud burst is advanced in urban compared to nearby natural areas. In some birds,

Cross-Linker Mediated Biofunctionalization of Single Wall Carbon Nanotubes with Glucose Oxidase

Covalent attachment of biomolecules to the surface of carbon nanotubes provides an architecture for three dimensional arrays of sensor molecules (i.e. enzymes) for potential biosensor application. Present work reports a simple two-step reaction for immobilization of glucose oxidase on single walled carbon nanotubes (SWCNTs). This method is as efficient as conventional methods for biofunctionalizat

Malignant melanoma is one of the most aggressive tumors which often gives metastasis to distant organs thereby limiting the chances of survival. Brain metastasis occurs in nearly half of the advanced tumors. In order to improve outcome early diagnosis is important. The discovery and better understanding of genetic and epigenetic changes is essential for developing new effective therapies, which ca

Early onset of type 1 diabetes and educational field at upper secondary and university level : Is own experience an asset for a health care career?

Ill health in early life has a significant negative impact on school grades, grade repetition, educational level, and labormarket outcomes. However, less is known about qualitative socio-economic consequences of a health shock in childhood or adolescence. We investigate the relationship between onset of type 1 diabetes up to age 15 and the probability of choosing and completing a health-oriented p

Extreme MHC class i diversity in the sedge warbler (Acrocephalus schoenobaenus); Selection patterns and allelic divergence suggest that different genes have different functions

Background: Recent work suggests that gene duplications may play an important role in the evolution of immunity genes. Passerine birds, and in particular Sylvioidea warblers, have highly duplicated major histocompatibility complex (MHC) genes, which are key in immunity, compared to other vertebrates. However, reasons for this high MHC gene copy number are yet unclear. High-throughput sequencing (H

Risk of eating disorders in immigrant populations

Objective: The risk of certain psychiatric disorders is elevated among immigrants. To date, no population studies on immigrant health have addressed eating disorders. We examined whether risk of eating disorders in first- and second-generation immigrants differs from native-born Danes and Swedes. Method: All individuals born 1984–2002 (Danish cohort) and 1989–1999 (Swedish cohort) and residing in
