Popular Abstract in English Look around and notice how many items have been manufactured or transported using petroleum-based products. In modern life, it is almost an impossible task to exclude them from our daily routine. They are present in plastics, cosmetics, cleaning products, medicaments, food, etc. To diminish our dependence on the demanded black liquid, a lot of research efforts have beenDepletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. Efficient processes for the conversion of pla

A new negligible depletion extraction procedure was proposed for equilibrium sampling of 4-tert-octylphenol (OP) and 4-nonylphenol (NP) into a thin film of 1-octanol supported on a hollow fiber membrane. This thin liquid film extraction technique was directed at the determination of ( 1) freely dissolved concentrations, ( 2) distribution coefficients to 1-octanol (D-ow), and ( 3) binding to dissol

AIMS: This post hoc analysis of the ATHENA trial (NCT00174785) assessed the effect of dronedarone on the estimated burden of atrial fibrillation (AF)/atrial flutter (AFL) progression to presumed permanent AF/AFL, and regression to sinus rhythm (SR), compared with placebo. METHODS AND RESULTS: The burden of AF/AFL was estimated by a modified Rosendaal method using available electrocardiograms (ECG)

The Altajme drillcore was recovered from near Buttle in central Gotland in 2015. The core was drilled in outcrop belt of the late Wenlock (Silurian) Klinteberg Formation as a result from an international drilling campaign between the Department of Geology at Lund University and Iowa University, USA. The coring continued to the top of the underlying Ordovician strata at a depth of ca 330 m. In this

The age of the center of our galaxy is poorly known. Determining the ages of individual stars in the galactic center usually requires isochrone fitting on a Hertzsprung-Russel diagram, which in turn requires knowledge of the star’s fundamental parameters, such as surface gravity, which is often determined with spectroscopic methods; and metallicity, which affects the shape of the isochrone. This c

How many times have you heard that if children are in church they should be quiet and still? It was common to hear when I was young that children should go out as soon as they started making any noise. It was and is always a pleasure for everyone to hear the cute children singing a pretty song in church but afterwards there should be silence again! What I want is for the congregation to accept the

We present a simple reduction of the problem of nondecreasing paths (with minimal last edge weight) in a directed edge-weighted graph to a reachability problem in a directed unweighted graph. The reduction yields an alternative simple method of solving the single-source nondecreasing paths problem in almost linear time. If the edge weights are integers then our algorithm can be implemented in O((n

Field experiments with ISA (intelligent speed adaptation) were carried out in Hungary and Spain in 2003 and 2004, respectively. Twenty private vehicles in each country were equipped with two kinds of systems: (1) support via an active accelerator pedal (AAP) and (2) warning via beep signals and a flashing red light when the speed limit was exceeded (BEEP). The test drivers drove for a month with b

Osteoclasts are derived from hematopoietic stem cells (HSCs) and form upon stimulation of osteoclast precursors by macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor κΒ ligand (RANKL). Osteoclasts resorb bone by secreting hydrochloric acid, matrix metalloproteinases (MMPs) and cathepsin K. Failure of bone resorption or bone formation results in metabolic bone disOsteoclasts are derived from hematopoietic stem cells (HSCs) and form upon stimulation of osteoclast precursors by macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor κΒ ligand (RANKL).

In this work we present the quasi-steady state simulation of a regenerative organic Rankine cycle (ORC) integrated in a passenger vessel, over a standard round trip. The study case is the M/S Birka Stockholm cruise ship, which covers a daily route between Stockholm (Sweden) and Mariehamn (Finland). Experimental data of the exhaust gas temperatures, engine loads, and electricity demand on board wer

In many financial applications, it is important to classify time-series data without any latency while maintaining persistence in the identified states. The authors propose a greedy online classifier that contemporaneously determines which hidden state a new observation belongs to without the need to parse historical observations and without compromising persistence.
