Data on the Populations of Bombina variegata (Amphibia: Anura: Bombinatoridae) from Cozia National Park and Its Surrounding Areas (Vâlcea County, Romania)
Authors: Iftime Alexandru , Iftime Oana 
Published: February 2018

Abstract
The results of surveys upon the Bombina variegata populations in the Cozia National Park are presented. 52 location points were found. The species is widespread in the investigated area, is resilient to some extent to the current level of natural and human disturbance, is moderately anthropophilic and shows evidence of previous introgressive hybridization with B. bombina. The habitats of the various populations in the area show different quality, connectivity and dynamics. These data should be useful for any management strategy for Bombina variegata in the National Park and its surrounding areas.

Published: February 2018

AbstractWe studied various aspects regarding migration behavior of the Common Buzzard for two subspecies (B. b. buteoandB. b. vulpinus) transiting the region which overlaps with the Western Black Sea Corridor. Using vantage points set across Dobruja we managed to count 2,662 individuals. We highlighted the seasonal and diurnal peak passage, flight directions and height of flight for each season. Our results suggest that 57% of the counted individuals belongs to long-distance migrant Steppe Buzzard -B. b. vulpinus. The peek passage period in autumn migration was reached between the 26thof September to the 6thof October, while for the spring migration peek passage remained uncertain. The main autumn passage direction was from N to S, and NNW to SSE but also from NE to SW. For spring passage the main direction was from S to N but also from ESE to WNW. Flight height during autumn migration was mostly at high altitude while in spring migration was more evenly distributed. The most significant activity was recorded in the second time period, between 10:01 and 13:00 (43%).

Authors: Prakash Jyoti , Kumar Pankaj , Kumari Kultaran , Manan Shweta 
Published: February 2018

Abstract
The effect of magnetic-field-dependent (MFD) viscosity on the thermal convection in a ferromagnetic fluid in the presence of a uniform vertical magnetic field is investigated for a fluid layer saturating a densely packed porous medium using the Darcy model. A correction is applied to the model by Sunil et al. [Z. Naturforsch. 59, 397 (2004)], which is very important to predict the correct behaviour of MFD viscosity. A linear stability analysis is carried out for stationary modes. The critical wave number and critical Rayleigh number for the onset of instability, for the case of free boundaries, are determined numerically for sufficiently large values of the magnetic parameter M
1. Numerical results are obtained and illustrated graphically. It is shown that MFD viscosity has stabilizing effect on the system, whereas medium permeability has a destabilizing effect.
Nonlocal Symmetries, Conservation Laws and Interaction Solutions of the Generalised Dispersive Modified Benjamin–Bona–Mahony Equation
Authors: Yan Xue-Wei , Tian Shou-Fu , Dong Min-Jie , Wang Xiu-Bin , Zhang Tian-Tian 
Published: February 2018

Abstract
We consider the generalised dispersive modified Benjamin–Bona–Mahony equation, which describes an approximation status for long surface wave existed in the non-linear dispersive media. By employing the truncated Painlevé expansion method, we derive its non-local symmetry and Bäcklund transformation. The non-local symmetry is localised by a new variable, which provides the corresponding non-local symmetry group and similarity reductions. Moreover, a direct method can be provided to construct a kind of finite symmetry transformation via the classic Lie point symmetry of the normal prolonged system. Finally, we find that the equation is a consistent Riccati expansion solvable system. With the help of the Jacobi elliptic function, we get its interaction solutions between solitary waves and cnoidal periodic waves.
Thermal Conductivity of Hydrated Paste in Cement-Based Foam Microstructure
Authors: Batool Farnaz , Bindiganavile Vivek 
Published: February 2018

Abstract
This article presents the thermal constants of hydrated cement paste, which constitute the air-void wall of cement-based foam microstructure, and examines its influence on moisture, age, pozzolanic admixture type, and content. Along with the reference mix, containing portland cement only, six other mixes were prepared by replacing cement with fly ash, silica fume, and metakaolin, up to 20 % by mass in the binder. The Transient Plane Source, a thermal analyzer that conforms to ISO test standards, was employed to evaluate the thermal constants. Here, the measurements were made at 60, 120, 210, and 300 days. The results revealed that the drop in thermal conductivity for the cement paste was significant in the earlier age but progressively became insignificant as the hydration advanced. It was also found that adding fly ash and silica fume in higher dosages resulted in reducing the conductivity, while metakaolin exhibits a reverse trend. Furthermore, the reduction in the moisture content due to pozzolanic admixture was also noticed. Finally, an empirical formulation was developed to predict the thermal conductivity of the hydrated cement paste, which was also validated against the results of past research.
DNT-Based Image Illumination Refinement System with Concurrent Copyright Embedding
Authors: Lee Jung-San , Wang Yi-Hua 
Published: February 2018

Abstract
Media archiving is the process of transforming a source to its digital form. This process, however, often leads to the irregular distribution of image illumination, which distorts the content of images. In this article, we propose a hybrid illumination technique based on double Niblack thresholds (DNT-based) to refine the brightness of underexposed and overexposed images, including the text image and the text-photo image. In particular, we introduce the watermarking concept to the transformation so that the improver can demonstrate the copyright of this refinement in the future. Experimental results have shown that the new method can effectively adjust the illumination to improve the quality of digital images without influencing the appended watermark.

Authors: Nadarajah S. , Bagheri S. F. , Alizadeh M. , Samani E. Bahrami 
Published: February 2018

Abstract
We propose inference of the stress strength parameter, R=P(Y&lt;X), when X and Y are independent generalized exponential-Poisson random variables. The problem of classical and Bayesian estimation of R is discussed. The Metropolis-Hastings algorithm is used to approximate the posteriors of R. Bayesian informative priors are considered under symmetric and asymmetric loss functions. Asymptotic confidence intervals for R are proposed. Monte Carlo simulations are performed to compare the proposed methods. At the end, a real dataset is analyzed for illustrative purposes.
Evaluation of Asphalt Effect on Water Quality Using Leaching Test and Molecular Simulation
Authors: Chen Jun , Wang Hao , Wu Jiantao , Xu Guangji 
Published: February 2018

Abstract
The contact of water and asphalt in roadway pavement can lead to the leaching of components from asphalt and cause water contamination. In order to study influencing factors affecting water contamination caused by asphalt materials, leaching tests were performed on asphalt mixture specimens with different mix designs. Chemical oxygen demand (COD), pH value, and total hardness are used to evaluate the leachability of asphalt mixture. The thin film leaching tests were carried out using a self-developed pressurized device. The effects of asphalt type, pH value of water, and submersion time on the concentration of ten metal ions leached from asphalt film were investigated. Finally, molecular dynamics simulations were performed to investigate the molecular diffusion between asphalt components and water. Results indicate that the concentration of metallic elements was affected by the pH value of water and submersion time. Compared with aged and SBS (Styrene-Butadiene-Styrene)–modified asphalt, virgin asphalt has the higher leaching potential for water contamination. The light fractions of aromatic and saturate molecules are more likely to diffuse at high temperature and high pressure. The study results can help better understand the environmental impact of asphalt in the framework of life-cycle assessment.
Fracture-Toughness and Fatigue Crack Growth Evaluation in the Transversal Direction of the Longitudinal Weld of an API X52 Steel Pipeline
Authors: Angeles-Herrera D. , Albiter A. , Cuamatzi-Meléndez R. , Terán G. , Ochoa-Ruiz Gilberto 
Published: February 2018

Abstract
In this paper, the fracture-toughness and fatigue crack growth rates of the deposited seam weld on the longitudinal pipeline API 5L X52 were evaluated. The study was performed with nonstandard curved specimens, which were machined in the transversal direction of the seam weld with a crack-initiating notch aligned perpendicular to the direction of the deposited seam weld metal. The fractographic analysis showed that the low fracture-toughness of the weld can be attributed to the the existence of elements capable of nucleating brittle fracture and the fact that the intrinsic porosity in the transversal direction provided a favorable crack path for separating the fracture plane, resulting in low fracture-toughness values. Finally, the resistance decrease with respect to the fatigue crack growth was attributed to the small grain size because of the effect of roughness-induced crack closure as well as the interaction of the crack and the inherent porosity.
Optimization of Heating Cycles Prior Forging for Large Steel Ingots Based on a Simulation Model
Authors: Romano-Acosta L. F. , Álvarez-Elcoro I. , Zapata-Hernandez O. , Leduc-Lezama L. 
Published: February 2018

Abstract
A simulation model has been used to calculate temperature distribution and internal stresses of steel ingots. The aim of this study is to optimize the heating cycles without compromising the mechanical integrity of the ingots, which ideally will result in a reduction in energy consumption and an increase in furnace productivity. The heating cycles of three ingots of different materials (ASTM A105, AISI 4330, and AISI 8630) and sizes (1.60, 1.75 and 1.32 m) are optimized. The optimization procedure of the heating cycle is based on a time reduction at each step of the set point. The phase transformation temperature at the ingot center was taken as a reference because this is where the higher stresses are developed. A sample of a 1 m Ø AISI 8630 ingot was characterized with a Scanning Electron Microscope, Energy-dispersive X-ray Spectroscopy, X-Ray Diffraction, and Differential Scanning Calorimetry. Results show precipitates in the as-cast condition, which will eventually be dissolved after a complete heating cycle.

Molecular detection of Brucella in milk using polymerase chain reaction
Authors: Mohsen A. 
Published: February 2018

Brucellosis is a highly contagious disease affecting a wide variety of farm animals. It is also an important zoonosis, and man is often infected following contact with infected animals or the consumption of contaminated milk and milk products. At present, mainly bacteriological and serological detection methods are used. A bacteriological method takes days to weeks to grow the organism besides its health hazard. Serological tests are faster but antigen–antibody interactions can be faulted by non-specific interactions. A method for direct detection of Brucella melitensis in 1 ml of milk was developed on the basis of enzymatic treatment of milk components and subsequent PCR and line probe assay (LPA). After PCR, 3 × 104 CFU/ml sensitivity was obtained by agarose gel electrophoresis and LPA. The safety and sensitivity of LPA combined with its speed suggests the potential of this technique for diagnosis of brucellosis in milk rather than the time consuming classical methods.

Potential +420 mV was applied to the electrode against saturated calomel electrode. Maximum current was observed at pH 6, linearity of response ranged from 0.01mM to 0.29mM. Concentration of potassium ferricyanide 2mM was found as the best value.
Proof of authenticity of pure instant coffee
Authors: Bohačenko I. , Veselý Z. 
Published: February 2018

An HPLC method with refractometric detection was worked out for the determination of the limiting contents of marker saccharides (free mannitol and total glucose and xylose) used for the proof of authenticity of pure instant coffee. This method, even though more laborious, yields results comparable with those obtained by the HPAE-PAD method and is intended mainly for those laboratories where the current HPLC technique with refractometric detection is presently used for saccharide analysis. The survey of market supply showed that instant coffee imported in bulk and subsequently packaged in the Czech Republic is most frequently adulterated – only one out of 7 samples examined contained authentic coffee. On the other hand, only one out of 10 samples of instant coffee imported in original packaging did not meet the authenticity criteria. The samples of instant coffee by domestic producers indicated that one producer placed on the market an adulterated product, whereas the other brand is authentic coffee.

Thirty-six samples of sesame (15 F1 and 15 F2 generations and their 6 parents) were evaluated for their reaction to Fusarium oxysporum f.sp. sesami (Zaprometoff) Castellani after artificial inoculation in greenhouse tests. The experimental soil was analysed mechanically and microbiologically. Reactions of the plants were recorded on a scale from 0 = no visible infection (immune) up to 6 = 70% infected plants (highly susceptible). Highly significant differences of susceptibility and resistance to the wilt pathogen were observed among hybrids and their parents. The level of infection in the parental generation varied from 2.22 to 63.77% (mean at 33.74%), in the F1 from 13.46 to 73.78% (mean at 32.09%), and in the F2 populations from 0.71 to 59.4.5% No population was immune. Nine lines of the F1 were classified as resistant (R) and three of them had the same rank in the F2. Only one parent (P3) and three lines from the F2 (13, 9 and 12) showed infection below 10% and were identified as highly resistant (HR) by infection rates of 2.22%, 0.71%, 6.08% and 9.57%, respectively. They can thus be considered as promising parents for breeding programs.
