The Effects of Gold and Silver Nanoparticles on an Enzymatic Reaction Between Horseradish Peroxidase and 3,3',5,5'-Tetramethylbenzidine

The purpose of this investigation was to study the effects of gold (Au) and silver (Ag) nanoparticles on a commonly used enzymatic reaction between horseradish peroxidase (HRP) and the substrate, 3,3',5,5'-tetramethylbenzidine (TMB). Two different methodologies were used in this study. The first was the addition of small quantities of nanoparticles, directly onto a solution of streptavidin peroxidase (streptavidin bound to HRP), prior to its reaction with TMB. The second, was the addition of nanoparticles to immobilised streptavidin peroxidase, covalently bounded to wells of a microtitre plate. In both cases, reactions with TMB were measured by visible absorbance spectroscopy, using a microtitre platereader. The results indicate that both gold and silver nanoparticles have a significant affect; with gold suppressing the reaction and silver enhancing it.
Global financial crisis , ownership and bank profit efficiency in the Bangladesh ’ s state owned and private commercial banks Crisis financiera global , propiedad y eficiencia de las ganancias en los bancos comerciales estatales y privados en Bangladesh

This paper studies the impact of global financial crisis focusing on State Owned Commercial Banks (SCBs) and Private Commercial Banks (PCBs) ownership and others bank specific and macroeconomics factors influencing profit efficiency level of the Bangladesh banking sector. The Slack-Based Data Envelopment Analysis (SBM-DEA) method employed to compute the profit efficiency of 31 commercial banks operating in the Bangladesh over the years 2004–2011. Furthermore, the multivariate panel regression analysis framework based on the Ordinary Least Square (OLS) and Generalized Least Square (GLS) methods comprising the Fixed Effect (FE) and Random Effect (RE) models adopted to examine the determinants of banks profit efficiency. Results indicate the levels of profit efficiency on SCBs and PCBs are increasing by 3.7% and 5.8% during financial crisis years. However, over the period of post financial crisis years exhibited, profit efficiency levels on SCBs and PCBs are decreasing by 38.7% and 9.9%. Although profit efficiency levels on both ownership of banks show declining over the post financial crisis years, the PCBs still higher than SCBs (67.8% > 60.1%) but insignificantly different. Furthermore, the findings reveals that the relationship of size of bank, liquidity, economic growth and market concentration are significantly negative with profit efficiency of SCBs but positive to PCBs. Meanwhile, the factors of capitalization, credit risk and inflation ∗ Corresponding author. E-mail addresses: fakarudinkamarudin@gmail.com, fakarudin@upm.edu. my (F. Kamarudin).

Lateral Sinus Augmentation: A Simplified Safer Approach

Enlargement of the maxillary sinus often precludes implant placement in the posterior quadrant without augmentation to create increased bone height to stabilize the implant fixtures and provide load handling following restoration. Maxillary sinus augmentation has been a technical challenge due to the potential for tearing of the Schneiderian membrane during lateral window formation. This article will discuss and review unique instrumentation for a safer simpler approach to lateral window maxillary sinus augmentation.
Perspectives in ecoacoustics: A contribution to defining a discipline

Ecoacoustics is a new discipline that investigates the ecological role of sounds. Ecoacoustics is a relevant field of research related to long-term monitoring, habitat health, biodiversity assessment, soundscape conservation and ecosystem management. Several life traits of the species, populations, communities, and landscapes/waterscapes may be described by ecoacoustics. Non-invasive programmable recording devices with on-board ecoacoustic metric calculations are efficient and powerful tools to investigate ecological systems. A set of processes in four [adaptive, behavioural, geographical, ecosemiotic] domains supports and guides the development of ecoacoustics. The first domain includes evolutionary mechanisms that join sound typology with the physical and biological characteristics of the environment and create frequency partitioning among species to reduce competition. The second domain addresses interspecific signals associated with geophysical and anthropogenic sounds that operate to shape temporary acoustic communities and orient species to select suitable acoustic habitats. The third domain pertains to the geography of sound, an entity composed of three subordinate acoustic objects: sonotopes, soundtopes, and sonotones, which are operationally delimited in a geographical and temporal space by the distribution of the ecoacoustic events. The ecoacoustic events allow the classification of complex configurations of acoustic signals and represent the grain of a soundscape mosaic. The fourth domain operates by ecosemiotic mechanisms within the species level according to a function-specific perception of the acoustic information facilitated by encoding processes.
Education Web Information Retrieval and Classification with Big Data Analysis

This paper discusses the text mining method to obtain the education web information rules. The method can be applied to words and parts of speech in texts to record the two-tier structure of automatic mining. On the basis of the initial discovery of the labeling rules, we put forward the linguistic features based on words to expand the application of the approaches. The web information retrieval mechanism is proposed based on web content segmentation. In addition, we build a rule matching method to improve performance of rule utilization, in terms of information of interest to the user and the extent to the interesting part. In conclusion, the use of automatic labeling rules can make part of the tagging accuracy rate reach a new height.
On the separation pro fi le of in fi nite graphs

Initial steps in the study of inner expansion properties of infinite Cayley graphs and other infinite graphs, such as hyperbolic ones, are taken, in a flavor similar to the well-known Lipton–Tarjan p n separation result for planar graphs. Connections to relaxed versions of quasi-isometries are explored, such as regular and semiregular maps. Mathematics Subject Classification (2010). 05C15, 20F65.
IDENTIFICATION OF PVC BEATS BY NEURAL NETS

This paper describes the design, training and testing of an artificial neural network for classification of normal and abnormal premature ventricular contraction (PVC) beats in ECG signal. To carry out the classification task, we use the back-propagation (BP) learning algorithm. Two feature selections types were investigated with aim of generating the most appropriate input vector for the artificial neural network classifier (ANNC). The first selected information of each ECG beat is stored as 33-element vector; the second one is then reduced to a 10 dimensional vector using principal component analysis (P.C.A). The performance measures of the classifier will also be presented using as training and testing data sets from the MIT-BIH database
High-pressure behavior of 2M1 muscovite

Abstract The crystal structure and pressure influence (between 0-6 GPa) on 2M1 muscovite have been calculated by quantum-mechanical methods based on density functional theory (DFT) with optimized numerical LCAO basis sets and norm-conserving pseudopotentials. Tensions between 0.8 and 0 GPa have been also studied. Volumes as a function of pressure, computed from the generalized gradient approximation, are closer to the experimental data than volumes calculated from the local density approximation. The crystal structure, bond distances, and main geometrical features agree with previous experimental values. A third-order Birch-Murnagham equation is fitted, giving a bulk modulus of 60.1 GPa, which reasonably agrees with the experimental data. Axis compressibilities are slightly smaller than those of the experimental data. The most compressible axis is the c axis. Bond strains, angles, the main geometrical features, and polyhedral strains are studied as a function of pressure, and these vary according to the experimental behavior. Tetrahedral and angles and corrugation show an oscillating behavior in the range of pressures used. The most important compressibilities are those related to the interlayer space, as it corresponds to the weakest bonding in the structure. The highest compressibility in the T-O-T layer along the [001] direction is determined by the octahedral sheet thickness. The compressibilities along the a and b axes are determined by the tetrahedra, as the most compressible polyhedra, and the α angle. Therefore, with our results the utility of periodic DFT methods for studying crystal structure and the effect of hydrostatic pressure on 2M1 muscovite are once again validated, and they are suitable to describe the compression of the crystal structure in detail.
Phenotypic variation of F 1 and F 2 populations from three species of Solanum L. (Solanaceae)

Emerging chromosome types in some Solanum species underscore inherent potentials and possible>new and expanded genome. Interspecific crosses involving the varieties of Solanum melongena L. ,Solanum macrocarpon L. and Solanum aethiopicum L. were carried out to assess species phylogenetic relationships and the extent of evolutionary changes with a view to improving the agronomic characters in the hybrids. The dimensions of leaves, petals and fruits in the F1 hybrids were intermediate in values between parents while parental influence was significant in such characters as growth habit, inflorescence types and colour of flowers. Pollen viability was depressed from 97.3 – 71% in parents to 56.8 - 48.8% in the F1 and consistently lowered from 48.6 – 38.2% in the F2 hybrids but restored (63.8%) in an F 2 plant. Fruits were few on inflorescence, small sized with generally fewer seeds in the F1 (67 - 132) and F 2 (52 – 135) hybrids compared with the parents (87 – 384). A single flowered inflorescence from a cross (S. melongena ‘Melongena’ x S. aethiopicum) revealed a novel gene and possible selective ecological advantage over other hybrids. The incomplete restoration of some of the masked characters in the F 2 hybrids suggests a near-complete homogenization of parental genomes and/or chromosomal disharmony through silent genomic changes. These might have prevented sufficient chromosomal rearrangement and full homology for improved vigour in many of the F2 hybrids.
Faktor-Faktor yang Mempengaruhi Sistem Pengenalan Wajah Menggunakan Metode Eigenface pada Perangkat Mobile Berbasis Android

Human face recognition is one of the areas that is developing today. Various applications of this tool with capabilities range widely from the search of criminals, criminality, access system, and human interaction computers. This application uses an existing camera on android smartphones to capture a person's face, and then compared with a face that is previously kept and trained in the database. If the captured image matches the identity of the face in the database, the facial identification is successful; if it doesn’t then it will be declared a failure. Face recognition algorithms used is Eigenface algorithm derived from the OpenCV library, the library can be used to identify a person's face. The results of face recognition processing by using OpenCV Eigenface depends on lighting, the distance between subject and camera, view angle of the face, the expression/facial expressions, use of accessories, and change the background.
Monocular Vision-Based Guidance and Control for a Formation Flight

This paper describes a monocular vision-based formation flight technology using two fixed wing unmanned aerial vehicles. To measuring relative position and attitude of a leader aircraft, a monocular camera installed in the front of the follower aircraft captures an image of the leader, and position and attitude are measured from the image using the KLT feature point tracker and POSIT algorithm. To verify the feasibility of this vision processing algorithm, a field test was performed using two light sports aircraft, and our experimental results show that the proposed monocular vision-based measurement algorithm is feasible. Performance verification for the proposed formation flight technology was carried out using the X-Plane flight simulator. The formation flight simulation system consists of two PCs playing the role of leader and follower. When the leader flies by the command of user, the follower aircraft tracks the leader by designed guidance and a PI control law, and all the information about leader was measured using monocular vision. This simulation shows that guidance using relative attitude information tracks the leader aircraft better than not using attitude information. This simulation shows absolute average errors for the relative position as follows: X-axis: 2.88 m, Y-axis: 2.09 m, and Z-axis: 0.44 m.
KENAF FIBRES AS REINFORCEMENT FOR POLYMERIC COMPOSITES: A REVIEW

In a view to reduce the cost of production and the harmful destruction of our environment, so many research work has been conducted and still ongoing as to the possibility of using natural fibres that are wholly degradable in combination with biodegradable thermoplastic materials. This has shown significant result so far and this effort needs to be further consolidated so that our environment can be safe and saved from destruction. It is for this reason that this paper is geared through reviewing studied and published results and brings out converging problems associated with biodegradable composite and partially degradable ones so that these associated problems can be tackled in further research. This review however will focus on Kenaf; a very important natural fibre with robust mechanical properties. Good number of journal papers have been reviewed here that touch on cultivation of kenaf and its consequent effect, chemical treatment of natural fibres, matrix combinations, processing techniques, environmental effects on composite, critical fibre length, some works done on Malaysian cultivated kenaf and use of coupling agents to improve linkages between fibre and polymeric matrixes. Most of the studies so far discussed tend to arrive at the problem of wettability of the composites which inhibits further increase in fibre loading and consequent fibre pull-out. Various areas of further study have been highlighted to tackle the aforementioned problems in composite production.
Tuberculosis in buffalo: the first report on the phenotypic and genetic characteristics of the isolated organism in Western Azarbaijan, Iran

In most countries, tuberculosis caused by Mycobacterium bovis is mainly a disease of cattle but can infect buffalos too. The disease can be controlled successfully by mean of a test-and-slaughter program. In Iran testand-slaughter program has started since 1971 and prevalence of bovine tuberculosis reduces from 5% to less than 0.12% in recent years. In Western Azarbaijan, North West of Iran, the prevalence of bovine tuberculosis is 0.06%. Tracing the source of infection and finding the animal reservoirs is one of the important parts of an eradication program against bovine tuberculosis and that can be achieved by differentiation of M. bovis isolates. Molecular typing techniques are powerful tools for epidemiological investigations and have been extensively used for this purpose. To understand the molecular epidemiology of bovine tuberculosis in the region and possible role of buffalos, 140 specimens collected from buffaloes at abattoirs bacteriologically were cultured for Mycobacteria. Only one specimen was positive in culture. The isolate was identified as M. tuberculosis complex by conventional biochemical tests and PCR targeting the insertion sequence IS6110. Restriction fragment length polymorphism (RFLP) analysis with polymorphic GC rich repeat (PGRS) and direct repeat (DR) probes showed that this isolate is distinct from M. bovis BCG and M. bovis isolates (n=10) isolated from cattle at different provinces. This is the first case of infection with M. Tuberculosis complex in buffalos in Iran. The role of buffalos in transmission of infection to humans and animals needs to be investigated.
Establishing Straight Line Correspondence

Straight line segments are common in images of man-made environments. Due to their mathematical simplicity and the ease with which they can be extracted from images, they have been widely used in vision applications. This paper presents a method for extracting and corresponding line segments between two views. Line segments are extracted by detecting edges and then fitting straight lines to the resulting edge points. For each of the line segments extracted from one image, a set of potential matches in the other image is formed. The strength of each potential match is measured by a matching function based on a few line attributes. A relaxation labeling technique that imposes global constraints on line matches is then used to disambiguate line matches. Results from the application of the method on real images are also presented.
The Relationship between the Learning Organization Dimensions and Transformational Leadership in Petrochemical Industry in Iran

Nowadays, the external environment for many companies is characterized by turbulence associated with globalization, changing customers and investor demands, increasing product market competition, technology growth, considering knowledge and learning as the main assets of organizations and rapid increasing change and chaos. Some management sages advocated new “generative transformational” forms of learning to deal with an external reality in which everything is constantly evolving or “becoming”. These assumptions rise to the notion of learning organization. However, examining the relationship between learning organization dimensions and other organizational elements makes it possible to draw on suitable strategies in order to improve learning. In this study the relationship between learning organization dimensions in point view of Watkins and Marsick including continuous learning, dialogue and inquiry, team learning, embedded system, system connection, ,empowerment, Strategic leadership and transformational leadership have been investigated. This study is a descriptive correlational research. Considering goal, it is an applied research. Statistical Population of the study includes Iranian National Petrochemical companies that are 45. Due to the accessibility of the whole statistical population, in this research census sampling method has been used. Research findings showed a significant relationship between transformational Leadership and three dimensions (among 7 dimensions) of learning organization which consist of "continuous learning", "team learning", and "embedded system". In considering the triple levels of learning organization, the findings illustrated a significant relationship between transformational Leadership and two levels (group and organizational).
Design of Ergonomically Fit Classroom Furniture for Primary Schools of Bangladesh

Students spend a large portion of their time in school. In this broadened time of sitting, poor fitting furniture can cause various types of musculoskeletal disorders and discomforts. Thus, it is crucial to use anthropometric data to coordinate the arrangement of school furniture. To fulfill this perception, a survey has been conducted in 10 primary schools in Khulna, Bangladesh. Anthropometric measurements were accumulated from 300 students of these primary schools. Seven furniture dimensions were measured and fifteen anthropometric measurements were taken and they were compared to identify potential mismatch. A significant degree of mismatch was found between furniture and student anthropometric measurements. The results highlighted that desktop height and seat height were found too high and seat width was too small for all of the students. The paper also proposes furniture dimensions, which reduce mismatch percentage of students ranging from 90% to 10%.
