Comparative Calculation of the Fuel–Optimal Operating Strategy for Diesel Hybrid Railway Vehicles
Authors: Leska Maik , Aschemann Harald , Melzer Michael , Meinert Michael 
Published: July 2017

Abstract
In contrast to road-based traffic, the track as well as the corresponding duty cycle for railways are known beforehand, which represents a great advantage during the development of operating strategies for hybrid vehicles. Hence the benefits of hybrid vehicles regarding the fuel consumption can be exploited by means of an off-line optimisation. In this article, the fuel-optimal operating strategy is calculated for one specified track using two hybrid railway vehicles with different kinds of energy storage systems: on the one hand, a lithium-ion battery (high-energy storage) and, on the other, a double layer capacitor (high-power storage). For this purpose, control-oriented simulation models are developed for each architecture addressing the main effects contributing to the longitudinal dynamics of the power train. Based on these simulation models, the fuel-optimal operating strategy is calculated by two different approaches: Bellman’s dynamic programming, a wellknown approach in this field, and an innovative sensitivity-based optimisation.

Authors: Berta Lavinia , Gâz Andrei , Boda Francisc , Curticapean Augustin 
Published: July 2017

AbstractObjective: The main objective of this research is to find the coordination ratio between AsW9and Ag+, as a preliminary study for synthesizing a new silver-arsenotungstate complex. Material and method: The ligand:cation molar ratio in complexes was determined by conductometric and potentiometric titrations of AsW9with silver salts: CH3COOAg, AgNO3. Results: The ratio was obtained from the inflexion points of the curves when molar ratio was plotted versus conductivity, or from the equivalence point when silver added volume was plotted versus pH value. Each graphic shows one point of inflexion corresponding to 1:1.54 ratio of AsW9:Ag+. In the same manner, the equivalent volumes determined by graphical method gave the ratio 1:1.53. The spectral results confirmed that a AsW9:Ag+complex was formed since the ligand absorption maxima values have been changed from 190 nm to 197 nm in the case of using AgNO3and 196 nm for CH3COOAg corresponding to the W=Odbond, and from 246.5 nm to 274 nm (AgNO3) and 270 nm (CH3COO-Ag+) for the W-Ob,c-W bond. Conclusions: Silver cation exhibit a preference for AsW9in a ratio of 3 to 2. This ratio can be associated to a sandwich type arrangement, with two trilacunary Keggin building blocks incorporating 3 metal cations in a tetrahedral geometry.

Authors: Vlad Alexandru Robert , Hancu Gabriel , Kelemen Hajnal , Ciurcă Diana , Tero-Vescan Amelia 
Published: July 2017

Abstract
Sibutramine is a chiral anti-obesity drug which decreases food intake and increases energy expenditure. In therapy it is used as a racemic mixture; however both pharmacokinetic and pharmacodynamic data have revealed enantioselective behavior of sibutramine and its major active metabolites. Several chromatographic and electrophoretic analytical methods have been published so far for the chiral determination of sibutramine from pharmaceutical preparations and biological samples. The current paper aims to provide a systematic review of the stereochemical aspects and analytical methods used for the enantiodetermination of sibutramine and its active enantiomers covering the last 15 years.

Effect of Different Nitrogen Doses on Some Agricultural Characteristics and Alkaloid Content of Hyoscyamus reticulatus L. and Hyoscyamus niger L.
Authors: Kizil S. , Tonҫer Ö. , Sogut T. 
Published: July 2017

AbstractAlkaloids, nitrogen containing basic substance, have a complex structure. They are one of the most important groups of secondary metabolites, which is synthesized in roots and transported to other organs. Since alkaloids are nitrogenous compounds, the availability of nitrogen is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen affects yield and quality of medicinal plants, therefore, growers usually apply large amount of nitrogen to obtain high yields. The objective of the present study was to determine yield, yield components and alkaloid content of two henbane species (Hyoscyamus reticulatusL. andHyoscyamus nigerL.), collected from wild flora of South-eastern Anatolia, grown under four nitrogen applications (0, 50, 100 and 200 kg ha−1), in 2010-2011 growing seasons. In the field trial, plant height, stem diameter, number of branches per plant, number of capsule per plant, capsule width, capsule length, number of seed per capsule, 1000 seed weight, seed yield per plant and total alkaloid content were investigated. The results of study showed that nitrogen doses were found important for investigated characters but not important forHyoscyamusspecies. Seed yield per plant varied from 8.4 to 11.6 g per plant, their alkaloid contents were found between 0.14% and 0.21%.

Authors: Jani Laura , Hodas Roxana , Beganu Elena , Bordi Lehel 
Published: July 2017

Abstract
Coronary artery malformations are rare congenital abnormalities, which present non-specific symptoms such as atypical chest pain, malignant arrhythmia, or sudden cardiac death. The proper diagnosis of these abnormalities in emergency conditions can be very difficult, and noninvasive imaging techniques, such as computed tomography or magnetic resonance imaging, along with the gold standard represented by invasive coronary angiography, remain the most frequently used modalities for diagnosing these rare cases. We present four cases of coronary anomalies represented by an abnormal origin of the coronary arteries from the coronary ostium, presenting in emergency conditions with symptoms of acute myocardial infarction, which were diagnosed by urgent angiography.

Authors: Nielsen Peter , Michna Zbigniew , Sørensen Brian Bruhn , Dung Ngoc Do Anh 
Published: July 2017

AbstractLead times and their nature have received limited interest in literature despite their large impact on the performance and the management of supply chains. This paper presents a method and a case implementation of the same, to establish the behavior of real lead times in supply chains. The paper explores the behavior of lead times and illustrates how in one particular case they can and should be considered to be independent and identically distributed (i.i.d.). The conclusion is also that the stochastic nature of the lead times contributes more to lead time demand variance than demand variance.
Lean Production Development in SMEs: A Case Study
Authors: Majava Jukka , Ojanperä Tiina 
Published: July 2017

AbstractThe competitiveness of small and medium sized enterprises (SMEs) is vital for the European economy. Also, manufacturing is often the core competence of SMEs. Adopting lean philosophy is a viable and popular approach for developing production and enabling continuous improvement. Despite the increased interest in empirical lean research, the body of knowledge about lean manufacturing development in SMEs is currently insufficient. This paper describes a study of a lean development project in a Finnish-based manufacturing SME. A current state analysis and development proposals are presented. The project applies a framework that other SMEs can utilize in identifying their problem areas and creating development proposals for their production activities. The results of the study contribute to the existing body of knowledge in lean manufacturing. In addition, managers in SMEs can utilize the study results as a reference when designing production development projects.
What Drives Politicians to Run for Office: Money, Fame or Public Service?
Authors: Balian Arpie G. , Gasparyan Arman 
Published: July 2017

AbstractThis is a multiple case study that investigates the motivations and ambitions of politicians who run for elections. It uses a mixed research design that applies inductive reasoning in the collection and analysis of data from six communities of rural Armenia. Data-collection instruments include in-depth interviews, focus groups, field observations and community survey. Whereas the study considers various theories of motivation and ambition, the conclusive evidence shows that the attractiveness of office at the local-government level in smaller rural communities is not driven by financial considerations and is rather compelled by the desire to make a difference motivated primarily by personal interest in and dedication to bringing positive change in the quality of life in one’s own community. The study also shows that motivators oft en stem from several other factors, including one’s deep-rooted connection with the community, lineage, length of term in office, record of community satisfaction, resultant personal power built over the years in service and the need to be acclaimed by one’s own community. A derivative closely linked to the priority of building the personal reputation of an incumbent mayor is the resultant power of decision-making. These conclusions can be explained using the model offered by Besley and Ghatak (2005) where politicians view public service as a personal mission. This study connects personal drive to sense of community and ancestral presence. The study also explains why mission accomplishment is more attractive than personal profit-making and how the sense of community and ownership are linked to personal drive.

With a view to protecting areas lying near the Nysa Kłodzka river and in order to reduce flood wave in Wrocław Waterway System, construction of a water reservoir near Kamieniec Ząbkowicki is being planned. After analysing the hydrology and hydraulics of the river Nysa Kłodzka and the function of reservoirs in Kamieniec Ząbkowicki cascade, a numerical seepage model, based on finite element method (FEM) and taking into account bedrock geology, drainage design and dam sealing, has been proposed. Boussinesq’s mathematical model was used to calculate unconfined groundwater table and vector field of seepage velocity. Building a numerical terrain model and visualisation of the water table in GIS tools enabled presenting calculation results in 3-D space.
Krankheitsbewertungen von Personen mit chronischen Schmerzerkrankungen und ihr Zusammenhang mit Indikatoren der Spiritualität
Authors: Büssing Arndt 
Published: July 2017

Zusammenfassung
Untersucht werden sollte an einem Datensatz von 540 Frauen (Altersmittel 54 ± 13 Jahre) mit chronischen Schmerzerkrankungen, wie sie ihre Erkrankung bewerten und welche Zusammenhänge zwischen negativen und positiven Krankheitsinterpretationen auf der einen und Indikatoren der Spiritualität sowie der Lebensqualität auf der anderen Seite bestehen. Krankheit als sinnlose Unterbrechung fand die meiste Zustimmung, außerdem Krankheit als eine Herausforderung oder als etwas Wertvolles, sowie als Bedrohung und als Hilferuf. Insbesondere die positiven Sichtweisen wurden von Frauen mit einer spirituellen Haltung geteilt und von nichtspirituellen Frauen klar abgelehnt. Als Prädiktoren der negativen Sichtweisen von Krankheit erwiesen sich die Intention, vor Krankheit weglaufen zu können und eine geringe Lebenszufriedenheit, während sich im Regressionsmodell für die positiven und strategieassoziierten Sichtweisen vor allem die Fähigkeit zur Lebensreflexion und eine religiöse Praxis als positive relevante Prädiktoren erwiesen. Eine spirituelle Haltung war also vornehmlich mit der Sichtweise von Krankheit als etwas Wertvolles, an dem man wachsen kann, und als eine Herausforderung assoziiert. Hier stehen möglicherweise die überwindenden und transformierenden Effekte im Vordergrund, die im Sinne eines „inneren Wachstums“ interpretiert werden können.
Large Eddy Simulation of Secondary Flows in an Ultra-High Lift Low Pressure Turbine Cascade at Various Inlet Incidences
Authors: Hu Site , Zhou Chao , Chen Shiyi 
Published: July 2017

Abstract
Increasing the blade loading of a low pressure turbine blade decreases the number of blades, thus improving the aero-engine performance in terms of the weight and manufacture cost. Many studies focused on the blade-to-blade flow field of ultra-high lift low pressure turbines. The secondary flows of ultra-high lift low pressure turbines received much less attention. This paper investigates the secondary flows in an ultra-high lift low pressure turbine cascade T106C by large eddy simulation at a Reynolds number of 100,000. Both time-averaged and instantaneous flow fields of this ultra-high lift low pressure turbine are presented. To understand the effects of the inlet angle, five incidences of ‒10°, ‒5°, 0, +5° and +10° are investigated. The case at the design incidence is analyzed first. Detailed data is used to illustrate the how the fluids in boundary layers develops into secondary flows. Then, the cases with different inlet incidences are discussed. The aerodynamic performances are compared. The effect of blade loading on the vortex structures is investigated. The horseshoe vortex, passage vortex and the suction side corner vortex are very sensitive to the loading of the front part of the blade.

Authors: Barinova Sophia , Krupa Elena , Kadyrova Ulrika 
Published: July 2017

Abstract
The spatial distribution of species richness of phytoplankton was studied along the Balkhash Lake water area during the summer of 2004. With statistically weak connections of phytoplankton with environmental parameters, three-dimensional graphs revealed a complex character of its spatial variability in the gradient of environmental factors. Macrophytes had a stimulating effect on the species richness of planktonic algae. We found a correlation between species richness of Cyanobacteria, Chrysophyta, Euglenophyta and Dinophyta and the ionic composition of water. The important role of temperature was traced. Species richness of algal communities increased with increasing temperature in the gradient of nutrients and correlated with the abundance of macrophytes.
Distribution and abundance of Artemia salina in the Salt Lake Basin (Central Anatolia, Turkey)
Authors: Alaş Ali , Kaya Murat , Öktener Ahmet 
Published: July 2017

Abstract
In this study, the distribution and abundance of Artemia salina in 10 different stations of the Salt Lake basin were investigated. In addition, its relationship to pH, dissolved oxygen, temperature, electrical conductivity and water levels were analyzed. Field studies were carried out from July to August of 2010. Artemia salina was observed in five of these stations. Artemia salina was not seen in some stations that have high electrical conductivity. It is determined that, in the station named Tersakan Lake where electrical conductivity was 154 mS/cm, Artemia salina is more abundant when compared to the other stations. But as underground water pumps that are built for the irrigation of agricultural lands decrease water levels, Artemia salina’s life is under threat.

Authors: Bănăduc Doru , Curtean-Bănăduc Angela 
Published: July 2017

Abstract
The ecological state of lotic ecosystems occupied naturally by Barbus meridionalis, in the Vişeu Basin within the Maramureş Mountains Natural Park, vary among good to reduced. The inventoried human activities which negatively influence the ecologic state of the Barbus meridionalis species habitats and populations are the organic and mining pollution, and poaching. The habitats with low and inadequate conditions created a reduced status of the Barbus meridionalis populations; the status of Barbus meridionalis populations is not so much affected in the cases of habitats of average to good condition. Barbus meridionalis is considered a relatively common fish species in the researched watershed despite the fact that its populations ecological status has decreased from 2007-2015, but the restoration potential in the area for improving this species status is high.
Effect of Particle Size and Pretreatment on the Conductivity of Glass Powder during Compaction
Authors: Murawski Dawid , Behrens Harald 
Published: July 2017

Abstract
Physical properties of solid materials can be strongly modified by pressure treatment at elevated temperatures. This study focuses on the compaction-induced behavior of powdered amorphous solids using Li2Si3O7-glass as an example. Experiments were carried out on distinct fractions with particle sizes from <25 μm to 224–250 μm. Measurements of electrical conductivity using impedance spectroscopy were carried out in situ at pressures up to 930 MPa and at temperatures from 373 K to 667 K. Simultaneous monitoring of volume changes allows correlating conductivity and porosity of samples. To study the effect of adsorbed water on surfaces, the material was pretreated by flushing with water-bearing nitrogen before the experiment. Continuous increase of electrical conductivity upon pressurization was observed for all particle size fractions both in the brittle and in the plastic deformation regimes. The pressure derivative of DC conductivity strongly increases with grain size at low T (373 K). At high T (608–665 K) the effect is less pronounced due to the onset of welding of particles forming continuous pathways for charge transport without grain boundaries as barriers. Welding of particles occurs already at temperatures significantly below the glass transition temperature, induced by strong local forces at grain-grain contacts. No effect by pretreatment of glass powder with water vapor was observed at low temperature, while at high temperature surface modification by adsorbed water resulted in enhancement of electrical conductivity, probably caused by lowering of viscosity at grain surfaces, which facilitates welding of particles.
