Sustainable transition pathways for plastics

Plastic – the lightweight, flexible material created by humans – has been an amazing invention that changed the world and made us totally dependent on it. The past century saw the development of a number of synthetic plastic materials with different chemistries and properties suited for myriad applications unparalleled by any other natural material. However, the plastics are currently in focus not

Estimation of arterial pulse wave velocity with a new improved tissue Doppler method

The mechanical properties of the large arteries are important determinants in the circulation physiology. Quantities associated with vessel wall elasticity are of particular interest since they offer a possibility to separate diseased arteries from healthy. Pulse wave velocity (PWV) is a local measure of the arterial wall elasticity. This paper describes a new improved method for non-invasive loca

Anemia, which may develop due to direct effect of the virus or indirect effect of zidovudine a widely used antiviral agent for the treatment, is not an uncommon complication in human immundeficiency virus (HIV) infections. In this report, a 26 years old male HIV positive patient who developed rapid anemia in the HAART (Highly active anti-retroviral therapy) protocol including zidovudine, was prese

What is the origin of HIV as the plaque of our age? What was the way of transmission? Did it just cross from the primates to the human being or has it been introduced accidentally during the polio vaccine trials period in Africa? Is there any other risks in front of the human being, originating from the primates harbouring other viruses. In this review article, it has been tried to give up to date

Chopin : The Preludes and Beyond

The first study of this volume looks for reminiscences of Dies Irae in Chopin’s works. A great number of allusions and affinities are found in the preludes as well as in Chopin’s output. The study also yields insights into Chopin’s composition method. These intertextual findings are used in an attempt to establish the extra-musical content of the Second Ballade. Five preludes – A minor, E minor, B

Analytical Variations : Eight Critical Essays on Applied Music Theory

This book gives a critical account of various methods used in music analysis. In the first chapter, a number of current approaches such as semiotics, musical implications, Schenkerian analysis, and generative theory are demonstrated on Mozart’s K. 331 theme. Five essays deal with important concepts in music analysis: ambiguity, formal proportions, and similarity within and between works. A further

Fluid Sounds

Explorations and analysis of soundscapes have, since Canadian R. Murray Schafer's work during the early 1970's, developed into various established research - and artistic disciplines. The interest in sonic environments is today present within a broad range of contemporary art projects and in architectural design. Aesthetics, psychoacoustics, perception, and cognition are all present in this expand

Energy dispersive-EXAFS of Pd nucleation at a liquid/liquid interface

Energy dispersive extended X-ray absorption fine structure (EDE) has been applied to Pd nanoparticle nucleation at a liquid/liquid interface under control over the interfacial potential and thereby the driving force for nucleation. Preliminary analysis focusing on Pd K edge-step height determination shows that under supersaturated conditions the concentration of Pd near the interface fluctuate ove

Femtosecond X-ray absorption spectroscopy of a light-driven spin-crossover process

Understanding the initial steps during ultrafast molecular reactions involving large spin state changes is a vital goal in structural dynamics research. These involve knowledge of the geometric structure of the system. Ultrafast X-ray absorption spectroscopy with 50-100 picosecond time resolution establishes the geometric structure of the short-lived (τ = 0:6 ns) high spin state. Here we focus on

Nonvolatile two-color holographic recording in Tm-doped near-stoichiometric LiNbO 3

We have observed ultraviolet-induced visible absorption and performed two-color holographic recording at green, red, and near-infrared light in thulium doped near-stoichiometric LiNbO 3 crystal. The diffraction efficiency and sensitivity of the recording process at all wavelengths are increased by ultraviolet gating light. Characteristics of recording in the visible are explained by a two-center

Uncovering scientific and multimodal literacy through audio description

The paper focuses on skills and competences applied in audio description (AD) of a Swedish multimodal popular scientific journal. The journal is made accessible for blind and visually impaired audiences by producing an audio version of its verbal and visual contents. The task of the sighted audio describer is to create a verbal description of the contents that activates internal images of the blin

TP53 mutations and breast cancer prognosis : particularly poor survival rates for cases with mutations in the zinc-binding domains

Acquired mutations in TP53 as well as immunohistochemically detectable protein expression have been implicated as prognostic factors for breast cancer. We have evaluated the relationship between mutations detected in 119 breast tumours and various clinicohistopathological indices, stratifying the mutations according to the functional domains as defined by the recent elucidation of the crystal stru

Multiple splicing variants of the estrogen receptor are present in individual human breast tumors

Transcript variants of the estrogen receptor (ER) were investigated in 109 primary breast tumors using reverse transcription-polymerase chain reaction (RT-PCR) and primers allowing analysis of each internal exon. A high incidence of different ER variants was observed, each individual tumor often manifesting multiple variants coexisting with corresponding wildtype (wt) ER. These variants, by sequen
