The influence of a radiated heat exchanger surface on heat transfer
Authors: Morel Sławomir 
Published: May 2018

Abstract
The experiment leads to establish the influence of radiated surface development heat exchangers on the values of heat flux transferred with water flowing through the exchangers and placed in electric furnace chamber. The values of emissivity coefficients are given for the investigated metal and ceramic coatings. Analytical calculations have been made for the effect of the heating medium (flame) – uncoated wall and then heating medium (flame) – coated wall reciprocal emissivity coefficients. Analysis of the values of exchanged heat flux were also realized. Based on the measurement results for the base coating properties, these most suitable for spraying the walls of furnaces and heat exchangers were selected, and determined by the intensification of heat exchange effect. These coatings were used to spray the walls of a laboratory waste-heat boiler, and then measurements of fluxes of heat absorbed by the cooling water flowing through the boiler tubes covered with different type coatings were made. Laboratory tests and calculations were also confirmed by the results of full-scale operation on the metallurgical equipment.

Published: May 2018

Abstract
In accordance with priorities of sustainable development in Serbia, production and use of biomass is crucial for provision of annually renewable national sources of energy and for environmental quality conservation. Rural development has typically focused on improving agricultural production and promoting market orientation, however, as the examples of other countries in the EU accession process have shown (e.g. Slovakia), such an approach could threaten the survival of rural population. Biomass production is one of the key sectors with significant potential for diversification of rural economy. The results of multiannual research work supported by the Ministry of Education, Science and Technological Development of the Republic of Serbia through national scientific projects and several international initiatives are summarized in this paper. The research activities focus on Miscanthus × giganteus Greef et Deu. The production potentials of miscanthus on fertile and degraded soils were investigated since 2009 in experimental plots established on moderate and extremely degraded lands in Serbia, applying various agrotechnical measures in different ecological conditions. The results show that fertile agricultural land as well as moderate degraded areas provide suitable conditions for miscanthus biomass and viable rhizomes production for energy and ecoremediation purposes.

Authors: Petráš Rudolf , Mecko Julian , Petrášová Viera 
Published: May 2018

Abstract
Poplar clones reach a big advantage over other forest tree species in the production of large amounts of above-ground biomass in a relatively short time. To increase the efficiency of production during their short life cycle, it is necessary to optimize age of their felling maturity. It should be carried out in the stands age when its average production is highest. Mathematical models of yield tables were used to derive this production. Above-ground biomass production was expressed in natural units, volume (m3 ha−1) and the capacity of calorific value (GJ ha−1), but also in financial yield (€ ha−1) from the sale of timber assortments including energy chips from smallwood. In terms of financial yield, Robusta stands are mature between 23 and 35 years and I-214 stands between 18 and 32 years. Main financial yield per year, on average 200–1900 € ha−1, is expected from the production of assortments designed for classic industrial processing. Its increase by 50 to 100 € ha−1 is expected to be achieved by supplemental smallwood processing to energy chips. In terms of volume production and capacity of combustion heat, stands are mature about 5–7 years earlier.

Abstract
We present a case of a 51 year old multiple myeloma patient due to the complexity of his disease. After prior high dose therapy with cardiotoxic cytostatic drugs patient developed cardiac arrest due to a ventricular fibrillation. Cardiopulmonary resuscitation was successfully but the hematologist stopped the cytostatic treatment due to the high cardiac risk.
The only way to control his myeloma was an autologous transplantation but this also had a very high cardiotoxic potential due to the high dose of Melphalan administered as conditioning treatment.
We present the difficulties and the results of this complex case. It also arises the potential beneficial effects of the megadose of stem cells on the myocardium but this needs further studies.

Published: May 2018

Abstract
In this study nutritional values and seasonal availability of 43 local feed ingredients for pigs in Uganda, were estimated based on nutrient analyses and literature values, information needed to develop low-cost balanced rations for pigs on smallholder farms. Parameters considered were: concentration of ash, neutral detergent fibre (NDF), crude protein (CP), calcium (Ca), phosphorous (P), ether extract (EE), total lysine (Lys), standardized ileal digestible (SID) Lys, standardized total tract digestible (STTD) P (all as % of dry matter [DM]); digestible energy (DE), (kcal kg−1 of DM); and DM concentration. Concentration of DE, total Lys, SID Lys, and STTD P were estimated. Ingredient seasonal availability and relative importance were identified. Ground sun-dried fish (Rastrineobola argentea) had highest estimated DE concentration and Napier grass (Pennisetum purpureum) had lowest (4209 and 535 kcal kg−1 of DM, respectively). Ground sun-dried fish had highest CP and estimated total Lys concentration (59.9 and 6.7% of DM, respectively) and banana peel (Musa sapientum), had lowest (5.21 and 0.08% of DM, respectively). Milled ingredients sampled here had higher ash than in the literature (e.g. ground sun-dried fish 58.1 vs 15.9% of DM) likely indicating sand contamination. There were 3 seasons of availability of ingredients. Banana peel, maize bran, and sweet potato vine (Ipomoea batatas) were ranked highest; and commercially-prepared ration, and kale/collard greens (Brassica oleracea var. acephala), were ranked lowest as potential feed ingredients. Ingredients with nutritional profiles suitable for pigs are available but some only in certain seasons. Estimated nutritional values may assist in ration formulation.

Published: May 2018

Abstract
Milk consumption is important in the diet of all age groups because it provides important nutrients that are essential for humans. Children are the largest consumers of milk, thus, it’s very important that milk is free of toxic compounds that can be harmful for humans. Aim of the study was to determine the physico-chemical characteristics of some samples of milk powder for different stage of baby growing and for some samples of fresh milk: raw cow’s milk, milk trade and UHT type. The following physico-chemical properties: density, pH, acidity, the presence of acetone, enzymes, antiseptics, dry substance, the ash, total fat, saponification and peroxide index, total nitrogen and protein content were determined. Comparing the values of acidity for analyzed samples it can be concluded that the powder milk acidity value is much lower than the fresh milk. The presence of antiseptics and acetone was not identified, and amylase and peroxidase were found only in raw cow's milk. The highest protein content was found for milk powder (27.22%).
Kinetics of the thermal decomposition of pine needles
Authors: Dhaundiyal Alok , Gangwar Jitendra 
Published: May 2018

Abstract
A kinetic study of the pyrolysis process of pine needles was examined using a thermogravimetric analyser. The weight loss was measured in nitrogen atmosphere at a purge flow rate of 100 ml/min. The samples were heated over a range of temperature of 19°C–600°C with a heating rate of 10°C/min. The results obtained from the thermal decomposition process indicate that there are three main stages: dehydration, active and passive pyrolysis. The kinetic parameters for the different samples, such as activation energy and pre-exponential factor, are obtained by the shrinking core model (reaction-controlled regime), the model-free, and the first-order model. Experimental results showed that the shrinking model is in good agreement and can be successfully used to understand degradation mechanism of loose biomass. The result obtained from the reaction-controlled regime represented actual values of kinetic parameters which are the same for the whole pyrolysis process; whereas the model-free method presented apparent values of kinetic parameters, as they are dependent on the unknown function ϕ(C), on the sum of the parameters of the physical processes, and on the chemical reactions that happen simultaneously during pyrolysis. Experimental results showed that values of kinetic constant from the first-order model and the SCM are in good agreement and can be successfully used to understand the behaviour of loose biomass (pine needles) in the presence of inert atmosphere. Using TGA results, the simulating pyrolysis can be done, with the help of computer software, to achieve a comprehensive detail of the devolatilization process of different types of biomasses.

Published: May 2018

Abstract
This paper endeavours to highlight three aspects of postmodern landscape design: theoretical basis, composition and design elements. Postmodern theories, philosophy influenced the language of the postmodern landscape architecture and got materialized in the use of narratives, eclecticism, the Rhizome-principle. Postmodern landscape composition can be associated with anti-hierarchy, unusual structures, landforms, and playful moods. Postmodern design elements consist of the strong graphical use of colour and pavements, bizarre water features, unusual structures and buildings, postmodern sculptures and thematic garden details. 25 analysed projects try to capture the essence of postmodernism in landscape architecture as well as to reveal points of intersection within these projects.

Fibonacci words in hyperbolic Pascal triangles
Authors: Németh László 
Published: May 2018

Abstract
The hyperbolic Pascal triangle HPT
4,q (q ≥ 5) is a new mathematical construction, which is a geometrical generalization of Pascal’s arithmetical triangle. In the present study we show that a natural pattern of rows of HPT
4,5 is almost the same as the sequence consisting of every second term of the well-known Fibonacci words. Further, we give a generalization of the Fibonacci words using the hyperbolic Pascal triangles. The geometrical properties of a HPT
4,q imply a graph structure between the finite Fibonacci words.

Published: May 2018

Abstract
Two North American goldenrods, Solidago canadensis and S. gigantea, are listed among invasive species posing the greatest threat to species and ecosystems in Europe. Distribution of non-native goldenrods in Lithuania was studied during field trips conducted in 2012–2015 with additional usage of herbarium data. To date, S. canadensis occurs frequently, especially in the eastern part of the country, being the most abundant in Vilnius city, Tauragė district, Vilnius district and Pagėgiai municipalities. S. gigantea occurs frequently in the southern part of the country with the highest abundance in Kazlų Rūda municipality. A total area invaded by S. canadensis amounts to 1702 ha, and by S. gigantea – 411.5 ha. Both species occur mostly in abandoned fields and on roadsides, in communities of ruderal plants of the class Artemisietea vulgaris. The current distribution of S. canadensis and S. gigantea in Lithuania and their competitive potential suggest that these two species are likely to become more common and abundant in the future.

Published: May 2018

Abstract
Considering the operation characteristics of the high-speed PBN airway, we propose an aircraft agent structural model and a basic algorithm flow of decision-making by Multi-agent technique. According to the constraint of safe separation and speed with the aircrafts, making use of the car-following theory, the deceleration constraint model is built for a flight management system. When the front aircraft decelerates, the model can offer a speed adjustment proposal for the following aircraft. The model is built based on the minimal safe separation and speed interval constraint; each variable, influencing the deceleration of the following aircraft can be analyzed. Simulation analysis is carried out for different combinations of aircraft types, initial speed, safe separation and deceleration. The follow aircraft deceleration was calculated under different conditions and the results coincided with reality. It is proved that the model can provide safe separation between the two aircrafts.
Joint Resource Allocation Scheme for Device-To-Device Communication under a Cellular Network
Authors: Feng Chenwei , Chen Pingbo , Zhang Zewang 
Published: May 2018

Abstract
Device-To-Device (D2D) communication is a new technology that allows the mobile terminals to directly communicate with each other by sharing the resources of the cellular network under the control of a cellular system. D2D communication was introduced into the cellular network in order to improve the efficiency of resource utilization and increase the system throughput. However, there exist interferences between D2D links and cellular links due to the resource reuse. In order to efficiently limit the cases of interference, a joint resource allocation scheme for D2D communication under a cellular network is proposed. The scheme, based on the user’s Quality of Service (QoS), defines a new utility function to balance the increasing system throughput and the interference in the cellular users D2D communication. The optimal D2D transmitting power is obtained through optimizing the utility function by using the convex optimization theory. The simulation shows that the scheme can fulfill the user’s QoS requirements efficiently, improve the system throughput and the reliability of the resources as well.
