Published: November 2018

Submicrometre‐sized EuPO4 hollow spheres were synthesised by utilising the colloidal spheres of Eu(OH)CO3 as the sacrificial template, for the first time. The EuPO4 hollow spheres were investigated by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and photoluminescence, respectively. The EuPO4 hollow spheres exhibit red colour emission from 5 D0–7 FJ (J = 1, 2, 3, 4) transitions of the Eu3+ ions. The obtained EuPO4 hollow spheres may have potential applications in cell biology, drug release, diagnosis, due to the high chemistry stability and luminescence function.
Ecological intensification in multi-trophic aquaculture ponds: an experimental approach
Authors: Jaeger Christophe , Aubin Joël
Published: November 2018

As aquaculture production is increasing considerably, it needs to become more environment-friendly. Based on a participatory process, an ecologically intensive pond system was designed to test three hypotheses: a combination of intensive and extensive areas provides more ecosystem services than an intensive or extensive area alone; coupling a planted lagoon with an intensive pond decreases the latter's environmental impacts and maintains or increases its fish productivity; and using formulated feed in polyculture increases growth of all fish species. To test these hypotheses, we designed a specific integrated multi-trophic aquaculture system composed of a polyculture of common carp (Cyprinus carpio), roach (Rutilus rutilus) and tench (Tinca tinca) and a lagoon planted with macrophytes to filter the water. This pond system was compared with “extensive” (unfed) and “semi-intensive” fishpond systems without a planted lagoon. We measured fish growth performances, water quality, chlorophyll concentrations and water and sediment nutrient contents. We also calculated the mass balance of nutrients. Concentrations of total nitrogen and phosphorus increased in sediments, indicating that nutrients were stored in the ponds, especially in planted lagoon; the planted lagoon decreased phytoplankton development, and limited blooms, but it slightly decreased fish growth performances compared to those in semi-intensive fishponds. The formulated feed supplied clearly increased fish growth performances and the survival rate, and seemed also to increase the use of available nutrients in ponds, which improved the production of overall fish biomass. In conclusion, the planted lagoon provides ecosystem services on nutrients cycling and habitat for natural biodiversity. Improving knowledge about nutrient cycles from formulated feed within the pond food web would be useful to increase the amounts of nutrients converted into fish biomass.
Picking a way forward: valuing and managing traditional shellfish gathering for Littorina littorea
Authors: Johnson Mark P. , Mcdermott Tommy
Published: November 2018

Littorina littorea (periwinkles) have been harvested by hand picking from the shore since prehistoric times. Harvests are generally unregulated, catches are not linked to particular shores and fisheries statistics are considered to be unreliable. The absence of key data has made it difficult to develop harvesting recommendations. Surveys around Strangford Lough, Northern Ireland were used to investigate the size structure and relationships among densities in different size classes. Three size classes were identified in surveyed L. littorea, with mean shell lengths of 0.81, 1.56 and 2.48 cm. Assuming that the age classes represent year classes, data across different shores suggested that the ratio between densities in successive year classes was not constant. Proportionally fewer individuals were found in the larger, older, size class as the density of the smaller size class on a shore increased. This density-dependent relationship was modelled with a Ricker curve for the year 1 to year 2 and the year 2 to year 3 transitions. The predicted transition rates from Ricker curves were used in a size-structured model to describe L. littorea dynamics. An emergent property of the size-structured model is a decline in mean shell length with overall density of a population. This prediction was supported by the survey data from Strangford Lough and by an independent survey of Irish shores. The size-structured model predicts potential harvests of individuals above 2.06 cm as a function of recruitment rate. Maximum harvest was predicted for a density of 5 year 1 individuals m−2, leading to 13.8 year 3 individuals m−2 or an estimated annual harvest weight of 67 g m−2. Modelled estimates of production provide a means to value shores and develop harvest predictions for management purposes.

In this work, the supercritical water gasification of eucalyptus wood chips has been investigated in relation to reaction temperature and presence of catalyst. Experiments were performed in a batch reactor at 450 ºC and 500 ºC with two different feed concentrations. This work wanted to evaluate mainly the gases were formed during the reactions. The gas products were analysed by gas chromatography. According to the results, it was found that eucalyptus wood chips reacted to form mainly H2, CH4 gases with little yield of CO2. Increasing the reaction temperature beyond 500 ºC led to the increasing production of both CH4 (around 31.1 mol%) and H2 (up to 38 mol%) gases and the liquid sample and solid residue have decreased. Generally, this work suggests that the SCWG has improved significantly the production of H2 but more experiments still necessary to verify the effects of other experimental parameters and to characterise the liquid sample and solid residue.

Authors: Stibbe L. , Giovanetti A. , Khan S. , Fontaine S.
Published: November 2018

In a context of world energetic mix diversification and greenhouse effect reduction, attention is focusing on renewable and carbon free sources. Amongst them marine sources are attractive ones by their huge potential today globally evaluated at world scale as high as 120.000TWh/year. They include osmotic energy one, which has been up-to-now left aside because of technological constraints and prohibitive exploitation cost. Reduction of their impact implies two possible actions : to operate the plants at a maximum efficiency rate, and to improve membrane technology in order to significantly lower exploitation costs. These two actions can be developed independently and it is proposed in the present study to concentrate on the first point to maximize theoretical osmotic plant efficiency rate. The output is a set of relations between system parameters defining the “optimized” line along which the system ought to be operated. This first study opens for a parallel study the technical feasibility of such optimally designed membranes to be installed in the plants.

Published: November 2018

The paper gives a general statement of the problem of choosing the structure of energy sources of urban heat supply systems to meet technical, economic and environmental constraints. One of the effective approaches to solve such a problem is the construction and optimization of redundant schemes of technological structures of energy sources. A model based on the theory of energy hubs is presented as one of the methods for constructing the redundant scheme. The application of the theory of energy hubs for selecting the types of energy sources allows, in an enlarged form, selecting the main equipment of energy sources, and evaluating technical and economic indices, and the degree of negative impact on the environment (at the level of gross emissions of harmful substances into the atmosphere). A case study of modeling a redundant system for selecting the optimal structure of energy sources, considering the minimum atmospheric pollution, is illustrated.

Applying of pixels separation brightness threshold is usually used to find the object boundaries. It is proposed to use a method for dividing the brightness of pixels to assign them to one of the zones of the fuel jet. A low brightness area with higher concentration of fuel, and vice versa, a zone with sufficient brightness (except the background luminance) has a lower concentration. Studying the dynamics of the change in brightness in the zones of a jet, we can talk about the quality of fuel atomization nozzles that can be different under different conditions.

Authors: Pleshko Mikhail , Revyakin Alexei , Malishevskaya Natalia
Published: November 2018

Tunnel lining takes significant loads from moving vehicles. The consequences of their impact depend on the design of the railway track and the deformation characteristics of its elements. For their study, a numerical model of a circular tunnel has been developed. As a result of the model calculation, the values of the main vertical stresses in the main tunnel structures were obtained. It is established that with increasing loads from the wheel to the rail from 100 to 200 kN, the voltage on average increases by 50%. The stress distribution is affected by the rigidity of the elastic layer. When it increases, the vertical stresses in the sub-rail support decrease nonlinearly, while in traveling concrete they increase nonlinearly.

Authors: Bulíček Josef
Published: November 2018

The article is focused on timetable synchronization problem. Interconnection of urban public transport and long-distance transport in busy hubs is researched. Intension is to find adequate time positions of urban public transport arrivals and departures with an effort to minimize passengers’ time loss related to this interchange. Timetable of long distance transport is considered as constant (given). Timetable of urban public transport is result of optimization (and presupposed to be periodic). Nonlinear integer mathematical programming model is formulated. Model is implemented in Microsoft Excel Solver. Parallel way based on exhaustive-search algorithm is introduced as well. This algorithm provides extended set of output data able to be used in transport planning. Two different criterions are proposed. Each interchange (pair of vehicles) has the same weight in the case of uniform approach. Intensity approach considers interchanges as weighted by numbers of interchanging passengers. Some additional modifications of proposed model are mentioned for possibility to regard some important technological aspects and to reach more individualized solution. Model is illustrated by the case study located to Pardubice main station as a hub of passenger railway transport. Interface with urban public transport is mentioned as an illustrational example of synchronization.

International transport corridors and transborder movement of fictitious capital
Authors: Dinets Daria , Dzhavrshian Albert
Published: November 2018

The paper is devoted to the analysis of the peculiarities of international transport corridors as a provider of ideas and instruments of liberalization aimed at assigning transport infrastructure to transnational corporations under the auspices of the development of integration processes and their transport service. To achieve the goal of the study, the authors analyzed a wide range of theoretical and empirical data illustrating the claims of Western and, most recently, Eastern multinational corporations on the sovereignty of Russian infrastructure industries. If international transport corridors include transit through Russia, then participation in them takes the form of export of transport services. At the same time, if investments in infrastructure development are foreign, then the type of income for such operations can be considered as a land rent, since the benefits depend only on the ownership of large or small land plots. The article shows the logical transition from this conclusion to the conclusion about the formation of fictitious capital of Russian infrastructure industries as a result of their inclusion in the activities of international transport corridors. The second hypothesis, which is need to be proved or disproved, is the negative role of UTLC (United Transport and Logistics Company) in achieving rational and fair management of container transportations within the framework of the Eurasian Economic Union (EAEU). Summarizing the two lines of the study, the authors concluded that there are risks for national capital and qualitative indicators of the development of infrastructure industries as a result of the active development of international transport corridors.

Evaluation of the benefits of utilization of fly ash as a material for road subgrade
Authors: Obradović Nikola
Published: November 2018

The assessment of potential effects of the application of fly ash in road construction was based on the results of tests of fly ash from two thermal power plants in Serbia and three characteristic soil types: the medium plasticity clay, silty-sandy clay and high plasticity clay. The physical and mechanical characteristics of the stabilization of the above three types of soils with different percentages of fly ash and stabilizers (cement/lime) were determined in the study, and pavement designs for three traffic levels, from 1,000 to 10,000 vehicles/day were developed. The savings that can be achieved by using fly ash are going up to 16.8% depending on the type of material in the subgrade and the level of traffic. The potential savings are higher if the subsoil has lower bearing capacity, and if the traffic level is higher.

The paper shows that the contour of a sheet blank at all stages of superplastic forming can be described by application of the universal equations known as a "superformula" and "superellipse". The work provides information on the ranges of values of the coefficients entering these equations and shows that their magnitudes make it possible to additionally determine the level of superplastic properties of the workpiece metal, the shape of the shell being manufactured, the stage of superplastic forming, and the presence of additional operations to regulate the flow of the deformable metal. The paper has the results of approximation by the proposed equations of shell contours that manufactured by superplastic forming by different methods.

Authors: Minnullina Anna , Minnullin Ruslan
Published: November 2018

Methodical bases for performance evaluation of the road construction company which is carrying out highway construction are based on integrated indicator calculation. This indicator considers interrelation of various internal and external environment factors. These factors are subdivided into three main groups by the authors: organizational and technological factors, technical factors and financial and economic factors. The suggested method of integrated indicator calculation for performance evaluation has been tested in the Tyumen road construction company. Testing confirms an opportunity to estimate the company position and utilization flexibility of calculation in practice.
Application of public-private partnership mechanisms for competitive growth of inland water transport in Russia
Authors: Voskresenskaya Elena , Vorona-Slivinskaya Lybov , Ponomareva Tatyana
Published: November 2018

The article deals with urgent problems of transport system development in Russia, paying the particular attention to inland waterway transport. The research is focused on the investment in the development of road infrastructure and methods of investing transport projects using public-private partnership mechanisms. The main reasons constraining the development of inland water transport in Russia are the insufficient amount of funds contributed to the development of the industry and their occasionally unreasonable use. In recent years, the world trend is to attract not only owners, but also infrastructure users to finance the inland waterway transport industry at a time when the financing gap is significant. The authors concluded that the simultaneous implementation of measures combining the introduction of fees paid by user and involving the improvement of water transport infrastructure through the public-private partnership mechanisms would promote attracting additional sources of investment. These investments will help to accelerate the industry modernization and implement the innovative scenario for the development of national economy. The authors developed the new model of state policy on attracting extra-budgetary sources of financing to the inland waterway transport industry.
Experimental and numerical investigation on the impact of vacuum level on effective thermal conductivity and microstructure of carbon fibre reinforced epoxy composites manufactured by vacuum bag method

Published: November 2018

The physical properties of epoxy based carbon reinforced composites are highly anisotropic due to their directional structure and dependent on the manufacturing process parameters. Thermal conductivity was found to be dependent on the void volume fractions, which appear as a result of the insufficient vacuum level. In the proposed paper the multi-scale computational model of heat transfer across the carbon fiber-epoxy resin composite is proposed. The meso-scale effective thermal conductivities are determined with analytical formulae for isotropic and anisotropic media, the latter takes into account thermal resistance at the interface of fibres and epoxy resin. Proposed model is utilized to determine the effective thermal conductivity in the direction perpendicular to plies of composite. The influence of void fractions and the thickness of the composite on the effective thermal conductivity is investigated. The numerical outcomes underestimate the real variation in conductivity, which can be caused by change in carbon volume fraction of samples manufactured at different vacuum levels which was not considered in numerical computation.

Published: November 2018

In this paper, thermal properties of materials for evacuated insulation systems of double-walled cryogenic tanks were discussed. Than the comparison of insulation variants for LNG cryogenic road tankers was presented. The use of several layers of insulation made of materials such as aerogel and fiberglass or the use of multilayer isolation (MLI) has been compared to the use of perlite powder. The average heat flux through the tank walls and insulation system has been compared under different vacuum levels and in the absence of vacuum. The comparative analysis was performed by applying transient thermal analysis using finite element method.
