As an alternative to traditional top-down techniques for fabrication of one-dimensional devices we here report an approach wherein a bottom-up technique is used to create one-dimensional device structures. We use the vapor-liquid-solid growth method, in which a catalytically active gold nanoparticle forms a eutectic alloy with the nanowire constituents. Our method of growth allows atomically abrup

The linearly polarized photon beam for photonuclear researches has been produced at MAX-lab facility on the base of coherent bremsstrahlung process of electrons in a diamond crystal. Test experiments have been performed at electron energies 143.9 and 192.7 MeV with a diamond crystal 0.1 mm thick. The measured coherent bremsstrahlung spectra demonstrate typical features to be observed at higher ele

Community currencies have emerged as a tool for building more inclusive local economic development and governance. Grassroots organisations in Nairobi and Mombasa (Kenya) have been experimenting with this form of local monies. Communities in informal settlements in Kisumu have shown interest in introducing their own community currency. Challenges remain concerning the best diffusion strategy of su

The spectroscopic properties of a molecule is strongly dependent on interactions with the surrounding environment. We have used time dependent density functional theory (TDDFT) and a multilevel perturbation model to study the transition energies, polarizability, and dipole moments of a bacteriochlorophyll in an electric field. The perturbation Hamiltonian was constructed as to give an electric fie

OBJECTIVE: Accurate distinction between dementia subtypes is important for patient care and pharmacological treatment. Continuing systematic comparisons of clinical and neuropathological dementia diagnoses may provide a basis for further improvement of the diagnostic procedure. The purpose of this study was to investigate concordance between clinical dementia diagnosis and neuropathological findin

Introduction Survival after out-of-hospital cardiac arrest (OHCA) remains low. Early recognition by emergency medical dispatchers is essential for an effective chain of actions, leading to early cardiopulmonary resuscitation, use of an automated external defibrillator and rapid dispatching of the emergency medical services. Aim To analyse and compare the accuracy of OHCA recognition by medical dis

More than 20 years ago, an oxytocin/vasopressin-like peptide, CLITNCPRGamide, was isolated from the locust, Locusta migratoria [Proux JP, et al. (1987) Identification of an arginine vasopressin-like diuretic hormone from Locusta migratoria. Biochem Biophys Res Commun 149:180-186]. However, no similar peptide could be identified in other insects, nor could its prohormone be cloned, or its physiolog

For business and environmental reasons, increased understanding of green consumer behavior is essential. This paper addresses consumer adoption and non-adoption of a high involvement eco-innovation (the alternative fuel vehicle, AFV). The purpose is to integrate two research streams to explore factors driving and hindering adoption. The factors are rooted in environmental psychology research and t

Around the globe more than 350,000 citizens live with a sophisticated hearing aid device called Cochlear Implant. In many countries CI is an institutionalized medical procedure for restoring deafened with a technological sense of hearing but the social challenges for users is a largely unexplored issue. Addressing this social dimension, the article explores how Cochlear Implant works as a boundary

Aims: Chronic left atrial enlargement (LAE) increases the risk of atrial fibrillation. Electrocardiogram (ECG) criteria might provide a means to diagnose LAE and identify patients at risk; however, current criteria perform poorly. We seek to characterize the potentially differential effects of atrial dilation vs. hypertrophy on the ECG P-wave. Methods and results: We predict effects on the P-wave

Leukotriene B-4 (LTB4) is a potent lipid mediator of inflammation that acts primarily via a seven-transmembrane-spanning, G-protein-coupled receptor denoted BLT1. Here, we describe the synthesis and characterization of fluorescent analogs of LTB4 that are easy to produce, inexpensive, and without the disadvantages of a radioligand. Fluorescent LTB4 is useful for labeling LTB4 receptors for which n

A combination of hydrogen/deuterium (H/D) exchange and limited proteolysis experiments coupled to mass spectrometry analysis was used to depict the conformation in solution of HAMLET, the folding variant of human alpha-lactalbumin, complexed to oleic acid, that induces apoptosis in tumor and immature cells. Although near- and far-UV CD and fluorescence spectroscopy were not able to discriminate be
