摘要:This study investigated polycyclic aromatic hydrocarbons (PAHs) and hydrocarbon oil index (HOI) pollution in the soil on the territories of two former primitive asphalt pavement plants (APPs) in Estonia. The standard quantitative methods for the chemical characterisation of the o...

摘要:Shale oil sludge is a hazardous by-product of hydrocarbon production that needs an effective and safe degradation. Co-pyrolysis with oil shale is a promising method to efficiently render the sludge non-toxic. Pyrolysis of the mixture of oil shale and shale oil sludge was studied ...

摘要:Oil shales of various rank and origin from China, Estonia and the United States are investigated and their oxidation reactivities under simulated oxy-fuel combustion conditions, in air, and in 100% CO2 atmospheres explored. Independent of rank and origin, as the oil shale pyrolys...

摘要:This contribution presents the performed experiments and experimental setup in detail for future reference and the results of bending tests performed on steel fibre concrete beam specimen, which have been cut out of a larger plate. These beams have different fibre orientation dis...

摘要:Estonia’s main calcareous industrial waste output, such as burnt oil shale (BOS) from Narva Power Plants (PPs), cement kiln dust (CKD) from AS Kunda Nordic Tsement and municipal solid waste incineration (MSWI) residues from Iru Power Plant (PP), were all tested in a novel mi...

摘要:An evolutionary scenario of processes, especially of the thermodynamic processes, in a perpetually mass-generating Planckian model universe has been studied. This is a Milne-type flat-space, R = ct, model with steady radial mass flow as recently described by us. In this ‘Bro...

摘要:Some equivalent conditions for a topological algebra to be a Q-algebra have been studied by several researchers. They have studied Q-algebras, mainly for unital topological algebras. In this paper some equivalent conditions are studied to be a Q-algebra for non-unital locally pse...

摘要:The taxonomy of the Baltic Ordovician orthoidean brachiopods of the genus Cyrtonotella Schuchert & Cooper, 1931 is discussed, two neotypes are suggested and emended descriptions of species and subspecies are presented. This taxonomic revision of Cyrtonotella-like brachiopods...
