Influence of Injection Timing on Equivalence Ratio Stratification of Methanol and Isooctane in a Heavy-Duty Compression Ignition Engine

CO2 is a greenhouse gas that is believed to be one of the main contributors to global warming. Recent studies show that a combination of methanol as a renewable fuel and advanced combustion concepts could be a promising future solution to alleviate this problem. However, high unburned hydrocarbon (UHC) and carbon monoxide (CO) emissions can be stated as the main drawback in low load operations whe

Intensive computer-based phonics training in the educational setting of children with Down syndrome : An explorative study

Children with Down syndrome (DS) using intensive computer-based phonics (GraphoGame, GG) were studied. The children's independence and improvement in phonological processing, letter knowledge, word decoding, and reading strategies were investigated. Seventeen children (5-16 years) with DS participated in a crossover design through 8 weeks (one period), with three test sessions separated by 4 weeks

Förbudet mot rättsmissbruk i EU-rätten : En förändrad avvägning mellan rättssäkerhet och rättvisa i den svenska skatterätten

This dissertation concerns a legal development that is currently taking place in Sweden due to its membership in the European Union (EU). It analyses the impact of the EU legal principle on abuse of law (the abuse principle). This principle has been developed gradually under long time in EU law and clarifying rulings from the Court of Justice of the European Union (CJEU) on the general nature of t

Greenhouse gas observation network design for Africa

An optimal network design was carried out to prioritise the installation or refurbishment of greenhouse gas (GHG) monitoring stations around Africa. The network was optimised to reduce the uncertainty in emissions across three of the most important GHGs: CO2, CH4, and N2O. Optimal networks were derived using incremental optimisation of the percentage uncertainty reduction achieved by a Gaussian Ba

The properties and utility of less evaluative personality scales: Reduction of social desirability; increase of construct and discriminant validity.

Evaluative neutralization implies rephrasing items such that it is less clear to the respondent what would be a desirable response in the given population. The current research compares evaluatively neutralized scales measuring the FFM model with standard counterparts. Study 1 reveals that evaluatively neutralized scales are less influenced by social desirability. Study 2 estimates higher-order fa

High Octane Number Fuels in Advanced Combustion Modes for Sustainable Transportation

The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. Understanding
