In order to study the combustion characteristics, NOx emission and NH3 slip in a new trinal-sprayed precalciner, simulations of aqueous urea solution based selective non-catalytic reduction (SNCR) process were conducted by computational fluid dynamics this effects different injection heights, flow rates stratified under on SNCR studied. The results showed that field was symmetrically distribute...

The article analyzes suburban bus transportation with specific routes in the Republic of Sakha (Yakutia). For experimental study, route No. 101, «Yakutsk – Tabaga» a total length 31 km was chosen. schedule buses Municipal Unitary Enterprise «Yakut Passenger Transport Company (YAPAK)» on is shown. basic technical data PAZ-320412 studied. In accordance international regulations for buses, determi...

This work concerns the activities of European project BLAZE that aims to integrate a pilot-scale gasifier unit with Solid Oxide Fuel Cell (SOFC). The objective is identify optimal operating conditions for and hot gas cleaning conditioning produce H2-rich syngas contaminants levels within limits safe operation SOFC (750 mg/Nm3 75 toluene naphthalene, respectively). Experimental tests were carrie...

Anaerobically digested sewage sludge mixed with forest residues was pyrolysed at 800 °C, laboratory and pilot scale. The study quantified differences in char gas yields for tests carried out a simple fixed bed reactor rotating retort pyrolyser scale, when the residence time of feedstock 10 min both cases. yield from scale 4 % lower than while 15.7 higher. During pyrolysis anaerobically blended ...

We have developed a nanoscopic force sensor with optical readout. The sensor consists of a single-stranded DNA oligomer flanked by two dyes. The DNA acts as a nonlinear spring: when the spring is stretched, the distance between the two dyes increases, resulting in reduced Förster resonance energy transfer. The sensor was calibrated between 0 and 20 pN using a combined magnetic tweezers/single-m...

The relevance of selecting an appropriate bed material in fluidized gasification is a crucial aspect that often underestimated. ideal should be economical, resistant to high temperatures and have small chemical interaction with biomass. However, only the first such three aspects considered, neglecting biomass–bed effects develop at temperatures. In this work, olivine K-feldspar were upscale-tes...

The primary structure of a protein consists of a sequence of amino acids and is a key factor in determining how a protein folds and functions. However, conventional methods for sequencing proteins, such as mass spectrometry and Edman degradation, suffer from short reads and lack sensitivity, so alternative approaches are sought. Here, we show that a subnanometre-diameter pore, sputtered through...

The organic fraction of municipal solid waste (OFMSW) is recognized as a suitable substrate for the anaerobic digestion (AD) process and currently considered mature technology. A promising strategy to enhance biogas yield productivity co-digestion OFMSW with other biomass, such green (GW), mixture leaves, grass, woody materials originated from private yards public greenspace management. main li...

Bioactive 3-alkylpyridinium polymers (poly-APS) have recently been isolated from the marine sponge Reniera sarai. Previous results have shown that these molecules in aqueous solutions form supramolecular aggregates with an average hydrodynamic radius of 23 +/- 2 nm. To obtain additional evidences about the shape and the dimensions of poly-APS aggregates, we used atomic force microscopy (AFM) op...

A widely used class of models for stochastic systems is hidden Markov models. Systems that can be modeled by hidden Markov models are a proper subclass of linearly dependent processes, a class of stochastic systems known from mathematical investigations carried out over the past four decades. This article provides a novel, simple characterization of linearly dependent processes, called observab...
