Stability Characterization of Three Porous Layers Model in the Presence of Transverse Magnetic Field

The current study concerns, the effect of a horizontal magnetic field on the stability of three horizontal finite layers of immiscible fluids in porous media. The problem examines few representatives of porous media, in which the porous media are assumed to be uniform, homogeneous and isotropic. The dispersion relations are derived using suitable boundary and surface conditions in the form of two simultaneous Mathieu equations of damping terms having complex coefficients. The stability conditions of the perturbed system of linear evolution equations are investigated both analytically and numerically and stability diagrams are obtained. The stability diagrams are discussed in detail in terms of various parameters governing the flow on the stability behavior of the system such as the streaming velocity, permeability of the porous medium and the magnetic properties. In the special case of uniform velocity, the fluid motion has been displayed in terms of streamlines concept, in which the streamlines contours are plotted. In the uniform velocity motion, a fourth order polynomial equation with complex coefficients is obtained. According to the complexity of the mathematical treatments, when the periodicity of the velocity is taken into account, the method of multiple scales is applied to obtain stability solution for the considered system. It is found that a stability effect is found for increasing, the magnetic permeability ratio, the magnetic field, and the permeability parameter while the opposite influence is observed for increasing the upper layer velocity.
Immobilization of Bacilli in Various Matrices to Enhance the Utilization of Keratinase and its Comparison

Bioconversion of insoluble Keratin-rich waste in to soluble value added product is an alternative way for recycling recalcitrant waste from poultry and leather industries. Microbial keratinases are more prominent which target the hydrolysis of keratin. Immobilization of the cell/ enzyme is an approach known to increase the application potential of biocatalysts for recycling of the cells and increase the efficiency of enzyme utilization. In present investigation effect of various matrices to immobilize Bacillus cells for the production of Keratinase was studied. Matrices like sodium alginate, polyacrylamide, agar-agar and gelatin were used. Keratinase activity of immobilized alginate beads was significantly higher (424 - 385 KU/ml) when compared to polyacrylamide (237-208KU/ml), gelatin (12878KU/ml), agar-agar blocks (237-103KU/ml), both in terms of activity and stability of beads. Sodium alginate immobilized Bacilli were efficient in the production of Keratinase bringing 100% degradation of feather in 4-5 days similar to free cells. Further cells could be recycled up to 3 batches over 21 days, especially sodium alginate beads are repeatedly used which can withstand disintegration of bead stability making the process economical and viable.

Multimodel Approach for Modelling of Biotechnological Processes

ABSTRACT The implementation of functional state approach for modelling of biotechnological processes is considered in this paper. This concept helps in monitoring and control of complex processes such as bioprocesses. Using of functional state modelling approach for biotechnological processes aims to overcome the main disadvantage of using global process model, namely complex model structure and big number of model parameters, which complicate the model simulation and parameter estimation. The main advantage of functional state modelling is that the parameters of each local model can be separately estimated from other local models parameters.

Isolation and characterization of two malathion-degrading Pseudomonas sp. in Egypt

Pseudomonas aeruginosa and Pseudomonas mendocina degrading malathion were studied. Morphological, biochemical and 16S rRNA genes for bacterial identification were selected. Biodegradation of some organophosphorus compounds with the 2 bacterial isolates was determined by high performance liquid chromatography (HPLC). P. aeruginosa strain completely removed diazinon, malathion and fenitrothion, but not chlorpyrifos within 14 days. P. mendocina strain was not able to degrade malathion, diazinon and chlorpyrifos completely and no significant degradation for chlorpyrifos. The bacterial growth curve showed a steady increase in the two bacterial isolates masses during malathion degradation. The highest growth rates were with yeast extract, glucose and citrate for the 2 isolates, but not with phenol. Shaked high inoculum density with incubation at 30°C of malathion bacterial cultures were found to be the optimum conditions for malathion degradation. Bacterial culture extracts subjected to liquid chromatography/mass spectrometry (LC/MS) analysis revealed that the separated products were malathion monocarboxylic acid and malathion dicarboxylic acid. Molecular characterization of carboxylesterase enzyme revealed that carboxylesterase amino acid sequences of the 2 isolates showed high identity to other carboxylesterase enzymes of P. aeruginosa and P. mendocina, respectively. Phylogenetic analysis showed that P. aeruginosa was localized in a separate branch from other carboxylesterase producing Pseudomonas sp. So, it is suggested that this enzyme is a novel esterase enzyme. Use of pesticide-degrading microbial systems for removal of organophosphorus compounds from the contaminated sites requires an understanding of ecological requirements of degrading strains. The results provided an important insight into determining the bioremediation potential of both strains. But the mentioned bacteria cannot be the aim of bioremediation due to risk of public health hazard, hence these bacteria cannot be used in bioremediation but their purified enzymes could. Key words: Biodegradation, carboxylestrase, organopgosphorus pesticides, Pseudomonas aeruginosa, Pseudomonas mendocina.
Incremental integration of multiresolution range images

Abstract An efficient incremental algorithm for integrating overlapping, registered range images acquired from different points of view is presented. Every new range image, which is represented by a 3D triangular mesh, is merged with a second triangular mesh which represents the current reconstructed model. The merging process consists of three stages. The first stage finds the area of overlap between the new 3D mesh and the reconstructed model. Triangles that belong to the area of overlap of the coarsest mesh are removed. In the second stage, the boundary created after removing the previous triangles, along with its adjacent boundary from the unaltered (fine) mesh, are projected to a reference plane and triangulated with a 2D constrained Delaunay algorithm. Finally, the last stage projects the previous 2D mesh back to the 3D space, leading to a 3D mesh that sews the new range image to the current reconstructed model. The algorithm is suitable for integrating range images acquired with different spatial resolutions and containing one or more separate objects.
Quantum-Classical Interactions and Galois Type Extensions

An algebraic model for the relation between a certain classical particle system and the quantum environment is proposed. The quantum environment is described by the category of possible quantum states. The initial particle system is represented by an associative algebra in the category of states. The key new observation is that particle interactions with the quantum environment can be described in terms of Hopf-Galois theory. This opens up a possibility to use quantum groups in our model of particle interactions.
Identification of Two Cold Water-Soluble Polysaccharides from the Stems of Ephedra sinica Stapf

Two polysaccharides (ESP-A1 and ESP-A2) were isolated from the cold water extract of Ephedra sinica Stapf and purified through ethanol precipitation, deproteinization and by ion exchange and gel-filtration chromatography. Their molecular weight was determined using high performance size exclusion chromatog-raphy and evaporative light scattering detector (HPSEC-ELSD) and their monosaccharide composition was analyzed by high performance capillary electrophoresis (HPCE) based on pre-column derivatization with 1-phenyl-3-methyl-5-pyrazolone (PMP). It was shown that ESP-A1 consisted of xylose, arabinose, glucose, mannose and galactose and ESP-A2 consisted of xylose, arabinose, rhamnose and galactose, in a molar ratio (%) of 3.2: 61.1: 11.1: 12.9: 11.6 and 20.6: 67.7: 5.0: 6.7, respectively. The molecular weights (Mw) of ESP-A1 and ESP-A2 were 5.83 × 104 Da and more than 200 × 104 Da, respectively. To the best of our knowledge, two neutral polysaccharides are now being reported for the first time in this study.
AN EVOLUTIONARY ALGORITHM FOR THE OPTIMISATION OF THE DISTRIBUTED GENERATION DISPATCH

This paper presents a methodology for solving power dispatch problems in electrical power distribution and transmission networks through Evolutionary Algorithms (EA). Optimising the dispatch of distributed generation units embedded in high and medium voltage distribution networks will be discussed taking into account system capacity, voltage levels, electrical losses and generation costs. The basics of Evolutionary Algorithms is presented showing their elementary functionality, detailed characteristics and applicability, as well as the particular development for the proposed problem. Concerning the computational environment modelling, a network-planning integrated application is used to make networks editing and results displaying more efficient. The case study applied to an illustrative high voltage distribution network helps to explain the main purpose of this article as a contribution to the optimisation methods applied to electrical power system problems.
Organizational innovativeness: : Construct development and cross-cultural validation

Organizational innovativeness (OI) is a central concept in academic research and managerial practice. In many cases, OI has been operationalized as the number of innovations organizations adopt. In contrast, this paper conceptualizes OI as a five-dimensional construct (creativity, openness, future orientation, risk-taking, and proactiveness) representing the organizational climate, which refers to the organization's ability to generate ideas and innovate continually over time. The findings support the conceptualization and operationalization of the five-dimensional OI, validated in Norway, Israel, and Spain. These results shed new light on existing findings and can promote new research directions as well as guide strategic managerial decision-making.
Identification of constraints to bovine milk protein synthesis.

Our inability to alter significantly the concentration of protein in milk by manipulating the nutritional status of the cow has provided the impetus for the investigation of rate limiting factors for protein synthesis. One of the major rate limiting factors for these studies has been the lack of an immortal cell line expressing bovine caseins. We have therefore established a method for the biopsy of mammary epithelial tissue from the latepregnant cow with which to study regulatory mechanisms for casein and whey protein gene expression. Initial studies have identified a period of 3040 days from calving in which biopsied mammary tissue can be induced to express mRNA for both casein and whey proteins. This model has been used to demonstrate that the stress-induced peptide hormone, bendorphin is part of the inhibitory complex of factors that suppress milk protein expression. These studies suggest that the nutritional management of the cow during this period pre-calving may be important in minimising the impact of these factors on productivity during the subsequent lactation.
Unexpected Zero Bias Conductance Peak on the Topological Semimetal Sb(111)

The long-sought Majorana fermion is expected to manifest in a topological-superconductor heterostructure as a zero bias conductance peak (ZBCP). As one promising platform for such heterostructures, we investigate the cleaved surface of the topological semimetal Sb(111) using scanning tunneling microscopy and spectroscopy. Remarkably, we find a robust ZBCP on some terraces of the cleaved surface, although no superconductor is present. Using quasiparticle interference imaging, Landau level spectroscopy and density functional theory, we show that the ZBCP originates from a van Hove singularity pushed up to the Fermi level by a sub-surface stacking fault. Amidst the sprint to stake claims on new Majorana fermion systems, our finding highlights the importance of using a local probe together with detailed modeling to check thoroughly for crystal imperfections that may give rise to a trivial ZBCP unrelated to Majorana physics.
Characterization of a Neutrophilic, Chemolithoautotrophic Fe(II)-Oxidizing β -Proteobacterium from Freshwater Wetland Sediments

A neutrophilic Fe(II)-oxidizing bacterium (FeOB) isolated from Fe-rich freshwater wetland sediments has been phylogenetically and physiologically characterized. The 16S rRNA gene sequence of this organism (designated strain TW2) places it among the Rhodocyclus group within the β-proteobacteria. The closest known relative to strain TW2 is the heterotrophic perchlorate reducer Dechlorosoma suillum, with 94% 16S rRNA gene identity. TW2 grows chemolithoautotrophically with Fe(II) as an electron donor and O2 as an electron acceptor. Inorganic carbon fixation during growth on Fe(II) was demonstrated via H14CO3 − fixation experiments. The organism can also grow organotrophically with acetate as the sole carbon and energy source, and can utilize acetate as an auxiliary source of fixed carbon which enhances cell yield (2–3-fold) during lithotrophic growth on Fe(II). No other electron donors and no electron acceptors other than O2 were utilized. The organism's ability to grow with Fe(II) and acetate, along with its limitations with respect to electron acceptor utilization, suggests a specific adaptation to microaerobic niches in redox interfacial environments. The unique metabolism of strain TW2, together with the 16S rRNA sequence data, suggests that this organism represents a novel taxonomic group at the genus level.
Interaction between C-Reactive Protein and Phytochemical(s) from Calotropis procera: An Approach on Molecular Docking

The present study was attempted to detect potential phytoconstituents in C. procera against inflammation and pain. CRP is known to be increased up to 10,000 fold when acute inflammation take place in human. The interaction between C-reactive protein and phytochemical(s) from Calotropis procera was carried out with the help of molecular docking by using PyRx software (Ver. 0.8) and LigPlot software (Ver. 1.4) to compare energy value and binding site of phytochemicals in reference to established synthetic non-steroidal anti-inflammatory drugs (NSAIDs). The data suggest that the interaction between CRP and two phytochemicals namely methyl myrisate (-3.0) and methyl behenate (-3.2) showed close energy value (kcal/mol) and binding site in comparison to paracetamol (-3.9), ibobrufen (-4.2) while three phytochemicals viz. β-sitosterol (-5.6), uzarigenin (-5.5) and anthocyanins (-5.4) closely related to indomethacin (-5.2) in relation to energy value and binding site. In conclusion, based on molecular docking we found few phytochemicals of C. procera that can be used as lead compound(s) in future drug development as analgesic and anti-inflammatory agent at low cost. It is also suggested to carry out functional assay of predicted compounds to validate suitability of this lead.
Weak States, Weak Societies: Comparing New and Old Member States of the European Union

The transfer of rules, such as in the European Union's recent enlargements, requires well-functioning institutions of government as well as societal actors ready to engage with the new rules. Officials of the European Commission and other practitioners highlighted the need for both in the run-up to enlargement, while critics of the 2004 and 2007 rounds have faulted the state-centric approach employed by the EU for undercutting societal actors in the new member states. This paper examines data from the World Values Survey and World Bank Governance Indicators and shows that state capacity and organized interests do indeed go hand in hand: Among the 27 EU member states, countries that score high on good governance also have citizens engaged in interest organizations, volunteering for a broad variety of causes, and ready to participate in acts of protest. By the same token, in countries where governments struggle to deliver results, organized interests are insufficiently established and rarely in a position to perform governance functions. The data show systematic and statistically significant differences between old and new member states, with Eastern Europe lagging behind most of the older democracies on both dimensions, i.e. state capacity and civil society. Considerable variation within each block does not negate this basic gap. Rather than rely on nonstate actors to compensate for weak institutions of government, European policy makers need to invest in long-term efforts to strengthen state institutions and bring stakeholders into the processes of policy-making and implementation.
Payment Scale Economies and the Replacement of Cash and Stored Value Cards

Debit cards in Europe replace many medium value cash payments while stored value cards were designed to replace small value cash transac-tions. Unit cost considerations dictated a two-card (or single card) dual technology approach to cash replacement since unit costs were too high to use debit cards alone for low value transactions. We estimate payment scale economies and illustrate the change in processing volume likely needed to permit debit cards to cost-eÂ¤ectively replace a greater portion of smaller value cash transactions, allowing consumers and merchants to use increasingly a single cash replacement technology. Key Words : Debit cards, scale economies, cash replacement
Title Overlapping Subsampling and invariance to initial conditions

This paper studies the use of the overlapping blocking scheme in unit root autoregression. When the underlying process is that of a random walk, the blocks’ initial conditions are not fixed, but are equal to the sum of all the previous observations’ error terms. When nonoverlapping subsamples are used, as first shown by Chambers and Kyriacou (2010), these initial conditions do not disappear asymptotically. In this paper we show that a simple way of overcoming this issue is to use overlapping blocks. By doing so, the effect of these initial conditions vanishes asymptotically. An application of these findings to jackknife estimators indicates that an estimator based on moving-blocks is able to provide obvious reductions to the mean square error.
A Novel Approach for Channel Estimation for MIMO-OFDM Systems Using PDP Technique

Multiple Input – Multiple Output Orthogonal frequency Division Multiplexing (MIMO-OFDM) is considered as eminent technology in the world of wireless communication such as 3 rd Generation technology as well as WiMAX. The successful implementation of LMMSE channel estimator in MIMO-OFDM is based on the reduction in the distortions caused by various factors such as by null subcarriers and the residual noise caused by the insufficient number of samples for power delay profile (PDP) estimation. Hence, we proposed a PDP estimation technique for linear minimum mean square error (LMMSE) channel estimator in MIMO-OFDM system. The proposed technique effectively mitigates the distortions for accurate PDP estimation and the distortion caused by null subcarriers. In addition, this technique also reduces the correlation mismatch in the frequency domain. The output of LMMSE channel by using the proposed PDP estimate approaches that of Wiener filtering and Kalman Filtering as results of the mitigation of distortion effects.
A power stitching tool

For time-based studies, researchers need to repeatedly image plates, for example, of cell cultures. However, an optical microscope has a field of view smaller than a typical plate. It therefore generates a grid of overlapping partial images, and a stitching tool assembles a composite image, which may have tens of thousands of pixels per side. Stitching one such large image mosaic taxes the computing capacity of a high-end workstation. This becomes overwhelming when stitching repeat images taken over time. Most high-end microscopes come with their own imagestitching tool. However, these tools are often manufacturerspecific and require fully calibrated equipment, a condition that is not always realized. An alternative is to use a manufacturerneutral computational tool for image stitching. There are two broad sets of approaches for image stitching, known as feature based1 and Fourier-transform based.2 Feature-based approaches identify matching features in adjacent images and use these features to determine the extent of the overlap within the image pair. They will then use the overlap to transform the images and compose them into a single one. These approaches have gained widespread usage in consumeroriented digital photography under the label of ‘panoramic photography’ because they are fast and because consumers almost always take feature-rich pictures. The main drawback of these techniques is that they must use a ‘segmentation method’ to detect features of interest in images. By contrast, approaches based on Fourier transforms are more compute-intensive, but can reliably handle feature-poor images. Furthermore, the computational workload is more predictable as it does not depend on the presence and detection of features in images. Optical microscopy often has to process feature-poor images (e.g., sparsely populated cell cultures) and may be used to derive measurements (quantitative information such as counts, Figure 1. A stitched image with 18 22 tiles and linear blending. The image has 23 21K pixels. It has a 1GB file size.
FINITE ELEMENT MODELLING AND SIMULATION OF VEHICLE IMPACT ON STEEL SAFETY BARRIERS

This paper deals with a FEA simulation of the vehicle crash with steel safety barriers in ANSYS LS-DYNA® 15.0. Two types of safety barriers are used: JSNH4/H2 and JSAM-2/H2. A geometrical model of the barrier in the Modeler ANSYS® Workbench™ 15.0 was created and after that it was transformed into LS-DYNA® 15.0 to complete the crash test simulation. After computation in solver ANSYS LS-DYNA® 15.0 the results of the simulation such as impact forces, a body displacement and an integral energy were analyzed.
