Abstract 5 The techno-economic potential of the UK poplar wood and imported oil palm empty fruit 6 bunch derived bio-oil integrated gasification and Fischer-Tropsch (BOIG-FT) systems for the 7 generation of transportation fuels and combined heat and power (CHP) was investigated. The 8 bio-oil was represented in terms of main chemical constituents, i.e. acetic acid, acetol and 9 guaiacol. The co...

Flexible fuel vehicles (FFVs) are able to operate on a blend of ethanol and gasoline in any volumetric concentration of up to 85% ethanol (93% in Brazil). The estimation of ethanol content is crucial for optimized and robust performance in such vehicles. Even if an ethanol sensor is utilized, an estimation scheme independent of the ethanol sensor measurement retains advantages in enhancing the ...

Recent evidence suggests that cell-derived circulating miRNAs may serve as biomarkers of cardiovascular diseases. However, a few studies have investigated the potential of circulating miRNAs as biomarkers for left ventricular hypertrophy (LVH). In this study, we aimed to characterize the miRNA profiles that could distinguish hypertensive patients with LHV, hypertensive patients without LVH and ...

Necessary and sufficient stability criteria for Friedrichs' scheme and the modified Lax-Wendroff scheme with smooth coefficients are derived by means of Kreiss' Matrix Theorem and the first Stability Theorem of Lax and Nirenberg. In this note we derive necessary and sufficient stability criteria for Friedrichs' scheme and the modified Lax-Wendroff scheme [8] for the hyperbolic system n (1) ". =...

The non-locality of nature is one of the most profound notions of quantum mechanics (QM) and is closely related to the phenomena of entanglement. The latter occurs when a quantum state of at least two particles cannot be written as independent single particle states. The manifestation of entanglement can be observed by correlations between two systems with no classical analogue. Moreover, these...

The objective of this work is to model a pulverized coal power plant and some of its component units and to apply control based in the boiler following control approach, in order to analyse the control system and the power plant performance at different operational conditions. The ETI-CCS project comprises the modelling of the several components of the carbon capture and storage chain, starting...

Presenting the influence of compressed natural gas (CNG) used as alternative fuel on combustion an automotive diesel engine represents main objective this paper. The paper studies brake specific energetic consumption, in-cylinder pressure and rise rate, carbon dioxide, nitrogen oxides, smoke hydrocarbons emissions at 2000 rev/min 40%, 55% 70% load. Low content will determine lower CO 2 all load...

Natural geologic hydrogen (H2) could supply climate-friendly energy. We perform a prospective life cycle assessment (LCA) of generic natural H2 production and processing system, using engineering physics chemistry to estimate greenhouse gas (GHG) intensity. Our baseline case contains 85 mol % H2, 12% N2, 1.5% CH4. Well productivity, depth, other parameters use data from US wells. an open-source...

This study characterises materials that belong to the group of refuse-derived fuels (RDF). regarded as an alternative fuel is derived from industrial, municipal solid and commercial wastes. The aim this evaluate quality waste composition, demonstrate statistically different values energy efficiency waste. Data on incinerated were collected two sources. basic physical chemical parameters include...

Increased energy source demand has been the current driver of Malaysia’s economic growth. Renewable is therefore included in policy to diversify its resources. With 77% land directed for agriculture – particularly palm oil plantation, biomass from industries thus considered as a viable resource. In addition 18.56 million hectares tropical forest contributed substantial wood waste logging activi...
