Alternative fuels have been proposed as a means for future energy-secure and environmentally sustainable transportation. This review and benchmarking show that several of the alternative fuels (e.g. methanol, ethanol, higher alcohols, RME, HVO, DME, and biogas/CNG) work well with several different engine concepts such as conventional SI, DICI, and dual fuel, and with the emerging concepts HCCI, RC

Animal movement acts at multiple scales: it can shape the destiny of individuals and populations, govern community and ecosystem structure, and influence evolutionary processes and patterns of biodiversity. Recent technological advances, such as the revolutionary developments in tracking technology and remote sensing, provide fresh insights and the possibility to collect detailed data on where and

The chapter presents a methodological approach to the early process of producing portable audio design. The chapter high lights audio walks and audio guides, but can also be of inspiration when working with graphical and video production for portable devices. The final products can be presented within online and physical institutional contexts. The approach focuses especially on the relationship t

The emission spectrometer at Balder/MAX IV beamline is presented. Its unique features are described. Comparison is given with other types of curved crystals analyzers.

Within recent years, there has been a renewed focus on sound in urban environments. From sound installations in public space to sound festivals in alternative settings, we find a common interest in sound art relating to the urban environment. Artworks or interventions presented in such contexts share the characteristics of site specificity. However, this article will consider the artwork in a broa

Concerns about climate change, diminishing social acceptance of traditional fuels, and technological innovations have led several countries to pursue energy transition strategies, typically by massive diffusion of renewable electricity supplies. The German ‘Energiewende’ has been successful so far in terms of deploying renewable power, mainly by applying particular feed-in tariffs, and by bundling

In 1964 the electronic music studio EMS, Stockholm opened as a conventional analogue studio. The primary intension with the institution was to build the world’s most advanced hybrid studio and to conduct an international research program into sound and sound perception. With financial support from the Swedish government and by the effort of the studio director Knut Wiggen, these visions were reali

Solid-state and diffusion NMR spectroscopy are versatile tools that allow for studies of both structure and dynamics of complex solid and semisolid materials. We have developed a suit of pulse sequences based on polarization transfer that is readily applied to studies of formulations and their interactions with biological systems. In the present paper, we illustrate its applicability by using an i

The signal crayfish (Pacifastacus leniusculus) was introduced to Sweden in 1960, and it has a high commercial and recreational value, but it may also have negative effects on native ecosystems. To better predict how climate warming will affect population dynamics of this cool-water crayfish, we explored the role of temperature and density dependence as explanatory factors of the subsequent years’

Background: Asthmatic patients have higher microbiome diversity and an altered composition, with more Proteobacteria and less Bacteroidetes compared with healthy control subjects. Studies comparing airway inflammation and the airway microbiome are sparse, especially in subjects not receiving anti-inflammatory treatment. Objective: We sought to describe the relationship between the airway microbiom

A paradigm shift is needed to improve and personalize the diagnosis of infectious disease and to select appropriate therapies. For many years, only the most severe and complicated bacterial infections received more detailed diagnostic and therapeutic attention as the efficiency of antibiotic therapy has guaranteed efficient treatment of patients suffering from the most common infections. Indeed, t

Type 2 diabetic patients suffer from insulin resistance and reduced insulin secretion. Osteopontin (OPN), a versatile protein expressed in several tissues throughout the body including the islets of Langerhans, has previously been implicated in the development of insulin resistance. Here we have investigated the role of OPN in insulin secretion using an OPN knock out mouse model (OPN-/-). Ultra-st

Patients and methods A comprehensive literature search was conducted. We measured pooled rate of lesion visualization improvement and improvement in lesion detection comparing FICE settings 1 – 3 and WLE, for angioectasias and ulcers/erosions. Pooled results were derived using the random-effects model because of high heterogeneity as measured by I 2. Repeated-measures analysis of variance (ANOVA)

Background: Cannulation of the internal jugular vein may be associated with inadvertent puncture of the common carotid artery. Systematic use of ultrasound guidance has improved clinical success rates and reduced complications, but better knowledge of topographic relationships of the internal jugular vein and common carotid artery is desirable. This preclinical study was designed to determine by u
