Macroscopic Traffic Flow Control Via State Estimation
Authors: Abouaïssa H. , Majid H. 
Published: May 2015

Abstract
The studies presented in this paper deal with traffic control in case of missing data and/or when the loop detectors are faulty. We show that the traffic state estimation plays an important role in traffic prediction and control. Two approaches are presented for the estimation of the main traffic variables (traffic density and mean speed). The state constructors obtained are then used for traffic flow control. Several numerical simulations show very promising results for both traffic state estimation and control.
Public Transport Priority for Multimodal Urban Traffic Control
Authors: Bhouri Neila , Mayorano Fernando J. , Lotito Pablo A. , Haj Salem Habib , Lebacque Jean Patrick 
Published: May 2015

Abstract
In order to improve the travel time of surface public transport vehicles (bus, tramway, etc.), several cities use Urban Traffic Control (UTC) systems enabling to give priority to public transport. This paper reviews these systems. Further on after a debate on their insufficiencies in the global regulation of the urban traffic on a whole network, the paper proposes intermodal regulation strategies, operating on intersection traffic lights to regulate the traffic, favouring the public transport. All these strategies are based on the Linear Quadratic (LQ) optimal control theory, but they are different in their ways of taking into account the public transport in the optimization problem. The simulation tests are carried out in a network of eight intersections and two public transport lines.
facile, highly efficient and novel method for synthesis of 5-substituted 1H-tetrazoles catalysed by copper(I) chloride
Authors: Esirden İbrahim , Başar Erhan , Kaya Muharrem 
Published: May 2015

AbstractThe present study on tetrazole compounds, which have a wide area of application, proposes a new, simple and highly effective method. A series of 5-substituted 1H-tetrazoles were synthesised in DMF via the [3 + 2] cycloaddition reaction, in which different aryl nitriles with sodium azide were used and copper(I) chloride served as a catalyst. Short reaction times, high yields and simple procedures rendered this method attractive and useful for the organic synthesis of 5-substituted 1H-tetrazoles. A further advantage was the use of an environmentally friendly catalyst.
Polyethylene glycol and iron oxide nanoparticles blended polyethersulfone ultrafiltration membrane for enhanced performance in dye removal studies
Authors: Krishnamoorthy Rambabu , Sagadevan Velu 
Published: May 2015

AbstractUltrafiltration (UF) is one of the most widely used membrane technologies for the effective separation of macromolecules in feed solutions. However, despite good separation efficiency, the UF membranes made up of pure polymers suffer to a greater extent because of low flux problem, which affects the process time and load. To handle this limitation, the base polymer is blended with a suitable additive to modify the structural and surface morphology of the membrane to provide better fluxes. In this current study, a series of polyethersulfone (PES) UF asymmetric membranes blended with polyethylene glycol and iron oxide nanoparticles was prepared using the phase inversion technique. Prepared membranes were analyzed for their morphology, thermal stability, and membrane characterization. Morphology studies using scanning electron microscopy and atomic force microscopy confirmed the increase in the number of pores, pore size in support layer, and surface roughness in the blended membranes, ensuring the chances of enhanced flux. Surface hydrophilicity was increased with the increase in the iron oxide concentration in the composite membranes. Thermal analysis studies showed the better thermal stability of the blended membranes. Pure water flux of the prepared composite membranes was improved to a maximum of four times in comparison with pure PES membrane. Dye rejection studies clearly showed that the blended membranes almost had the same rejection as that of pure PES membrane. Thus, the prepared PES composite UF membrane is a promising candidate for the treatment of dye-polluted wastewater, ensuring high fluxes and effective rejection.

Published: May 2015

Abstract
By improving the air and water properties of soils, superabsorbent polymers can affect the increase and improvement of the quality of the yield of berry plants, including strawberries. Their presence in the soil has an influence on its biological activity as related to microorganisms. The aim of the research was to assess the influence of superabsorbent polymers added to the soil on the content of macroelements and sodium in the leaves and fruit of strawberry of the ‘Elsanta’ cultivar and changes in the number of soil bacteria, actinomycetes and fungi. The superabsorbent polymer (AgroHydroGel) was used in two doses: 1.8 and 3.6 g dm-3 of soil. The content of phosphorus, potassium, calcium, magnesium and sodium was assessed using the ASA method, while the content of nitrogen and sulphur was assessed by the elemental analysis method (CHNS analyser). The number of microorganisms was assessed with a BacTrac analyser and the coefficient of microorganism development extent (SR) was also determined. AgroHydroGel increased the content of nitrogen and potassium in leaves and fruit but did not affect the content of phosphorus, sulphur and sodium. The addition of the superabsorbent at a dose of 3.6 g dm-3 of soil reduced the magnesium content both in the leaves and fruit of the strawberry. AgroHydroGel decreased the content of calcium in the fruit. The use of AgroHydroGel contributed to the expansion of the K ion ratio to other ions, both in the leaves and fruits. We observed a significant increase in the amount of soil bacteria (1.8 g dm-3 dose) and no significant influence on actinomycetes and fungi (irrespective of dose used).
Influence of substrate pH on the growth and flowering of Mandevilla Lindl. Sundaville® ‘Pretty Red’
Authors: Kapczyńska Anna , Magdziarz Katarzyna 
Published: May 2015

Abstract
Sundaville is the brand name of a new collection of cultivars of the genus Mandevilla (syn. Dipladenia), with the potential to become a leading vine in the world horticultural market. The research was carried out in order to analyse the growth of Sundaville ‘Pretty Red’ at different values of substrate pH (4.0, 4.7, 5.3 and 5.5). The study shows that flowers appeared after more than six months irrespective of soil conditions. Plants cultivated at pH 4.0 had the longest leaves, but at the highest substrate pH the widest leaf laminae were observed. Regardless of the substrate pH, the diameter of a single flower remained the same. Plants cultivated at a pH lower than 5.0 produced more flower buds and more flowers in comparison with the plants exposed to the higher pH. Moreover, pH < 5.0 positively affected the number of stems. The soil pH did not only affect the growth, but also the health of the plants. The lowest pH level (4.0) caused adverse changes to the leaves.
A Novel Compact UWB Bandpass Filter with Quad-Notched Bands Based on S-SCRLHs Resonator
Authors: Xie Changming , Wang Chunhua 
Published: May 2015

Abstract
A novel compact ultra-wideband (UWB) bandpass filter (BPF) with a quad band-notched function using S-SCRLHs (splitted simplified composite right/left-handed) resonator is presented. The S-SCRLHs resonator, which exhibits quadruple resonance, is realized by coupling double S-SCRLH resonator. The S-SCRLHs resonator is integrated into a conventional UWB BPF. The notched frequencies can be adjusted according to specification by altering the S-SCRLHs resonator. Band-rejected filtering properties around the C-band satellite communication band, 5.2 GHz WLAN band and the X-band satellite communication band are generated. The notching frequencies are located at 4.2/5.2/6.3/7.8 GHz. Both simulated and measured results are provided with good agreement. Compared with other BPFs, the proposed BPF has the advantages of compact size, multi-stopband and good selectivity.

Authors: Jaswal Shipra , Gaur Bharti 
Published: May 2015

AbstractMethacrylated lignin model compounds (LMCs, i.e., eugenol and guaiacol) monomers are ideal candidates as styrene replacements because they have low volatilities and can free-radically polymerize with vinyl ester resins. This article reports the synthesis of methacrylated eugenol (ME), methacrylated guaiacol (MG) using LMCs and methacrylic anhydride in the presence of 4-dimethylaminopyridine (DMAP) as a catalyst. ME and MG were characterized using FT-IR,

Published: May 2015

Abstract
A light-colored hydroxypropyl sulfonated alkali lignin (HSAL) was synthesized based on pine alkali lignin (AL) by grafted-sulfonation and crosslinking reaction processes. The reactions were evaluated by gel-permeation chromatography (GPC), infrared (IR) and proton nuclear magnetic resonance (1H-NMR) spectroscopy. The sulfonic group content and the molecular weight (M

w
) of HSAL significantly increased, while the phenolic hydroxyl groups diminished by around 80% compared to AL. The color of HSAL turned to light yellow compared to the dark brown color of AL, that is, it stained less the fiber. The dispersity, heat stability, and dye uptake of dye bath with HSAL was significantly improved compared to sodium lignosulfonate, sulfomethylated AL, and dispersants of the naphthalene series.

Published: May 2015

Abstract
Both of the sphingosine kinase (SK) subtypes SK-1 and SK-2 catalyze the production of the bioactive lipid molecule sphingosine 1-phosphate (S1P). However, the subtype-specific cellular functions are largely unknown. In this study, we investigated the cellular function of SK-2 in primary mouse renal mesangial cells (mMC) and embryonic fibroblasts (MEF) from wild-type C57BL/6 or SK-2 knockout (SK2ko) mice. We found that SK2ko cells displayed a significantly higher proliferative and migratory activity when compared to wild-type cells, with concomitant increased cellular activities of the classical extracellular signal regulated kinase (ERK) and PI3K/Akt cascades, and of the small G protein RhoA. Furthermore, we detected an upregulation of SK-1 protein and S1P3 receptor mRNA expression in SK-2ko cells. The MEK inhibitor U0126 and the S1P1/3 receptor antagonist VPC23019 blocked the increased migration of SK-2ko cells. Additionally, S1P3ko mesangial cells showed a reduced proliferative behavior and reduced migration rate upon S1P stimulation, suggesting a crucial involvement of the S1P3 receptor. In summary, our data demonstrate that SK-2 exerts suppressive effects on cell growth and migration in renal mesangial cells and fibroblasts, and that therapeutic targeting of SKs for treating proliferative diseases requires subtype-selective inhibitors.
The molecular medicine of acid ceramidase
Authors: Frohbergh Michael , He Xingxuan , Schuchman Edward H. 
Published: May 2015

Abstract
Acid ceramidase (N-acylsphingosine deacylase, EC 3.5.1.23; AC) is the lipid hydrolase responsible for the degradation of ceramide into sphingosine and free fatty acids within lysosomes. The enzymatic activity was first identified over four decades ago and is deficient in two rare inherited disorders, Farber lipogranulomatosis (Farber disease) and spinal muscular atrophy with myoclonic epilepsy (SMA-PME). Importantly, AC not only hydrolyzes ceramide into sphingosine within acidic compartments, but also can synthesize ceramide from sphingosine at neutral pH, suggesting that the enzyme may have diverse functions depending on its subcellular location and the local pH. Within cells, AC exists in a complex with other lipid hydrolases and requires a polypeptide cofactor (saposin D) for full hydrolytic activity. Recent studies also have shown that AC is overexpressed in several human cancers, and that inhibition of this enzyme may be a useful cancer drug target. Aberrant AC activity has also been described in several other common diseases. The cDNA and gene (ASAH1) encoding AC have been isolated, several mouse models of AC deficiency have been constructed, and the recombinant enzyme is currently being manufactured for the treatment of Farber disease and SMA-PME. Current information concerning the biology of this enzyme and its role in human disease is reviewed within.
Common Driving Notification Protocol Based on Classified Driving Behavior for Cooperation Intelligent Autonomous Vehicle Using Vehicular Ad-Hoc Network Technology
Authors: Lin Che-Hung , Dong Fang-Yan , Hirota Kaoru 
Published: May 2015

Abstract
A protocol, called common driving notification protocol (CDNP), is proposed based on the classified driving behavior for intelligent autonomous vehicles, and it defines a standard with common messages and format for vehicles. The common standard format and definitions of CDNP packet make the autonomous vehicles have a common language to exchange more detail driving decision information of various driving situations, decrease the identification time for one vehicle to identify the driving decisions of other vehicles before or after those driving decisions are performed. The simulation tools, including NS- 3 and SUMO, are used to simulate the wireless data packet transmission and the vehicle mobility; the experiment results present that the proposed protocol, CDNP, can increase the reaction preparing time with maximum value 250 seconds, decrease the identification time and the average travel time. Prospectively, it is decided to implement the CDNP as a protocol stack in the Linux kernel to provide the basic protocol capability for real world transmission testing.
On Merging and Dividing Social Graphs
Authors: Held Pascal , Dockhorn Alexander , Kruse Rudolf 
Published: May 2015

Abstract
Modeling social interaction can be based on graphs. However most models lack the flexibility of including larger changes over time. The Barabási-Albert-model is a generative model which already offers mechanisms for adding nodes. We will extent this by presenting four methods for merging and five for dividing graphs based on the Barabási- Albert-model. Our algorithms were motivated by different real world scenarios and focus on preserving graph properties derived from these scenarios. With little alterations in the parameter estimation those algorithms can be used for other graph models as well. All algorithms were tested in multiple experiments using graphs based on the Barabási- Albert-model, an extended version of the Barabási-Albert-model by Holme and Kim, the Watts-Strogatz-model and the Erdős-Rényi-model. Furthermore we concluded that our algorithms are able to preserve different properties of graphs independently from the used model. To support the choice of algorithm, we created a guideline which highlights advantages and disadvantages of discussed methods and their possible use-cases.

Published: May 2015

Abstract
With the growth of robot technology, robots that assist learning have attracted increasing attention. However, users tend to lose interest in educational-support robots. To solve this problem, we propose a model of emotional expression based on human-agent interaction studies. This model in which the agent autonomously expresses the user’s emotions establishes effective interactions between agents and humans. This paper examines the psychological effect of a robot that is operated by the model of emotional expressions and the role of this effect in prompting collaborative learning.

Authors: Wróblewska Anna , Stawiarz Ernest 
Published: May 2015

Abstract
Eighteen samples of honeys which were harvested over several beekeeping seasons from apiaries located in the area of the “Kózki” Nature Reserve (central-eastern Poland) were the subject of the present study. The “Kózki” Nature Reserve is included in the European Ecological Network Natura 2000 program. A microscopic analysis of the pollen sediment in the honeys showed the presence of 61 pollen types from 32 botanical families in the investigated material. There were represented by nectariferous (72.1%) and nonnectariferous plants (27.9%) and both entomophilous and anemophilous ones. The total number of pollen taxa in individual samples ranged from 13 to 37. The main sources of nectar from trees and shrubs were: Frangula alnus, Prunus, Robinia pseudacacia, Rubus, Salix, Tilia. The main sources of nectar from herbaceous plants were: Anthriscus, Brassicaceae, Caryophyllaceae, Centaurea cyanus, Taraxacum, and Trifolium repens. Four unifloral honeys (three fruit tree honeys and one lime honey) and fourteen multifloral honeys, with a significant percentage of pollen from several nectariferous plant taxa, were distinguished in the studied material.

Published: May 2015

Abstract
Exposure of A. mellifera workers to CO2 has been reported to decrease life span, induce behavioral changes, and inhibit the development of some glands and the ovaries. However, the use of CO2 is currently practiced among beekeepers and how the development of workers’ ovaries are affected is unknown. The present work aimed to evaluate the effect of CO2 on the ovaries of A. mellifera workers, using a morphological approach. Newly emerged, and 3, 5, and 10-day-old workers were exposed to saturated CO2 for 30 seconds, more than once. The ovaries were examined under light (LM) and transmission electron microscopy (TEM). The ovaries of narcotized, 5-day-old workers exhibited long ovarioles with well-developed germarium, although oogenesis showed little development. While in the control group, the ovaries already exhibited cysts with cystocytes forming rosettes. At 10-days-old, the ovaries feature was variable; some of the ovaries showed ovarioles with many rosette cysts while others showed a high intensity of disorganization due to the beginning of cell death. The ovarioles of the ovaries of 15-day-old treated workers were morphologically varied as oogenesis showed little or no advance. In others cases, a complete disorganization with swollen cells and cell death features were observed. Germ cells of the ovaries of CO2-treated workers exhibited well-structured organelles, such as the Golgi complex, and larger amounts of mitochondria in the cytoplasm than the control group, but there was disorganization of the endoplasmic reticulum membranes. Our findings revealed that the exposure of workers to CO2 promotes impairment of oogenesis and ovarian degradation.

Authors: Nakamichi Takeshi , Moroizumi Toshitsugu 
Published: May 2015

Abstract
The characteristics of evapotranspiration estimated by the complementary relationship actual evapotranspiration (CRAE), the advection-aridity (AA), and the modified advection-aridity (MAA) models were investigated in six pairs of rural and urban areas of Japan in order to evaluate the applicability of the three models the urban area. The main results are as follows: 1) The MAA model could apply to estimating the actual evapotranspiration in the urban area. 2) The actual evapotranspirations estimated by the three models were much less in the urban area than in the rural. 3) The difference among the estimated values of evapotranspiration in the urban areas was significant, depending on each model, while the difference among the values in the rural areas was relatively small. 4) All three models underestimated the actual evapotranspiration in the urban areas from humid surfaces where water and green spaces exist. 5) Each model could take the effect of urbanization into account.
Determinants of change in the duration of ice phenomena on the Vistula River in Toruń
Authors: Pawłowski Bogusław 
Published: May 2015

Abstract
Winter season temperatures are becoming warmer. However, the transformation of the ice regime on the Vistula River in Toruń has also been affected by river engineering. In particular, the construction and operation of the Włocławek Dam had a significant impact on ice processes. The article presents the results of an analysis determining the contribution of natural and anthropogenic factors to the duration of ice phenomena and ice cover on the Vistula River in the city of Toruń. Compared to the end of the nineteenth century, there has been a reduction in the duration of ice phenomena from 88 to 53 days and of ice cover from 40 to 7 days (in the period of 1882-2011). The article compares the duration of ice cover and winter temperature in three different periods: before the completion of river engineering works (1882-1907); for the controlled river (1908-1969), and for the controlled river with the Włocławek Dam upstream of Toruń (1970-2011). The results showed a significant role of these anthropogenic factors in the changes of the ice cover duration on the Vistula River in Toruń.
