Opis:: This paper covers the current state of maritime oil transportation in the Baltic Sea and the development of oil transportation in the 2000s, as well as estimations of transported oil volumes in 2020 and 2030 in the Gulf of Finland. The scenarios were formulated on the basis of a current state analysis, energy and transportation strategies and scenarios and expert assessments. The study showed that the volumes of oil transportation in the Gulf of Finland will increase only moderately compared to the current status: 9.5-33.8 %, depending on the scenario. Green energy policy favours renewable energy sources, which can be seen in the smaller volumes of transported oil in the 2030 scenarios compared to the 2020 scenarios. In the Slow development 2020 scenario, oil transport volumes for 2020 are expected to be 170.6 Mt (million tonnes), in the Average development 2020 187.1 Mt and in the Strong development 2020 201.5 Mt. The corresponding oil volumes for the 2030 scenarios were 165 Mt for the Stagnating development 2030 scenario, 177.5 Mt for the Towards a greener society 2030 scenario and 169.5 Mt in the Decarbonising society 2030 scenario.

Opis:: The fruit fly optimization algorithm (FOA) is a global optimization algorithm inspired by the foraging behavior of a fruit fly swarm. In this study, a novel stochastic fractal model based fruit fly optimization algorithm is proposed for multiobjective optimization. A food source generating method based on a stochastic fractal with an adaptive parameter updating strategy is introduced to improve the convergence performance of the fruit fly optimization algorithm. To deal with multiobjective optimization problems, the Pareto domination concept is integrated into the selection process of fruit fly optimization and a novel multiobjective fruit fly optimization algorithm is then developed. Similarly to most of other multiobjective evolutionary algorithms (MOEAs), an external elitist archive is utilized to preserve the nondominated solutions found so far during the evolution, and a normalized nearest neighbor distance based density estimation strategy is adopted to keep the diversity of the external elitist archive. Eighteen benchmarks are used to test the performance of the stochastic fractal based multiobjective fruit fly optimization algorithm (SFMOFOA). Numerical results show that the SFMOFOA is able to well converge to the Pareto fronts of the test benchmarks with good distributions. Compared with four state-of-the-art methods, namely, the non-dominated sorting generic algorithm (NSGA-II), the strength Pareto evolutionary algorithm (SPEA2), multi-objective particle swarm optimization (MOPSO), and multiobjective self-adaptive differential evolution (MOSADE), the proposed SFMOFOA has better or competitive multiobjective optimization performance.

Opis:: A cyclonic-static microbubble flotation column of a novel construction was used in oil-water separation fields and has high efficiency for oil-water separation. The gas holdup is a key parameter for the evaluation of the performance of a flotation column. The gas holdup, closely related to the bubble size, bubble velocity and superficial gas velocity, is one of the most important parameters characterizing the hydrodynamics of a bubble column. The effect of gas holdup in a cyclonic-static microbubble flotation column was investigated. In addition, several operating parameters such as the circulating pressure, superficial gas velocity, and frother consumption were also investigated. The gas holdup was positively correlated to the superficial gas velocity. The gas holdup of clean water and oil wastewater increased along with the increase of the frother consumption. The separation mechanism of cyclonic-static microbubble flotation column was analyzed.

Opis:: Estimation of tree biomass is an essential part of studies on carbon sequestration and cycling in forest ecosystem. Small trees grow in the understory and allometric development is different from that of mature trees. However, less attention has been paidto biomass estimates of small trees, especially in mixedforest where tree competition is intensive. Tree allometric equations at both branch level andat whole tree level were, thus, developed and compared for the small trees of Korean pine (Pinus koraiensis) in a mixedstandin northeastern China. At branch level, the best model for live branch biomass was one which used a combination of branch diameter, branch length, whorl position and relative branch depth. For needle biomass, the best model did not significantly improve the estimate with more variables. At whole tree level, stem diameter at breast height (DBH) was a significant determinant of biomass for different components. Tree height did not significantly improve biomass estimation at all. Tree crown variables provedto be useful for estimating all biomass components except the fine roots. The variable measuring abovegroundcompetition intensity was a significant negative determinant of biomass components except canopy biomass. Comparisons to published equations for the same species growing in Heilongjiang province in northeastern China andin central South Korea, were also presented. Both total aboveground biomass and belowground biomass in our study showed somewhat smaller values for a given diameter than the trees growing in other two places.

Opis:: Energetic salts of doubly-protonated 3-hydrazino-4-amino-1,2,4-triazole (2-4), and mono-protonated 3-hydrazino-4-amino-1,2,4-triazole (5-7), have been prepared in high yields from the corresponding oxygen-containing tetrazoles by (i) reaction of free acids and neutral 3-hydrazino-4-amino-1,2,4-triazole, or (ii) metathesis reactions of 3-hydrazinium-4-amino-1H-1,2,4-triazolium di-chloride with the silver salts of the corresponding oxygen-containing tetrazoles. All of these energetic salts were fully characterized by single-crystal X-ray diffraction, FT-IR and DSC measurements. All of the structures are dominated by extensive hydrogen bonds due to amino groups, hydrazino groups and oxygen atoms in the molecules. These salts exhibit good thermal stability, especially the salt 3-hydrazinium-4-amino-1H-1,2,4-triazolium 1H,1’H-5,5’-bitetrazole-1,1’-diolate (4), which exhibits a measured onset of decomposition temperature of 237 °C. Quantum chemical calculations, carried out using the Gaussian 03 suite of programs and based on the experimental densities were used to calculate the detonation pressures and velocities of all of the salts.
