Distribution & Preference of Entamopathogenic Bacteria across Different Soils of Karnataka

Photorhabdus is an effective biological weapon against insect pest of crop plants which act as syringe like mechanism and triggered death of pests with in 48 h. Photorhabdus luminescens is a symbiont of nematodes and a broad spectrum insect pathogen. This study aims to collect Entamopathogenic nematode (EPN) from different agro climatic zones of Karnataka and isolate Photorhabdus luminescens from them as it act as effective biocontrol agent against numerous insect pests. Entamopathogenic nematodes are collected from cultivated and noncultivated areas of different agro climatic zones of Karnataka using G. mellonella, a host susceptible to EPN by baiting method. Percent infection of G. mellonella larvae by EPN in soil across different locations was recorded. Photorhabdus bacteria were isolated and identified using standard synaptic keys according to Bergey’s Manual of Systematic Bacteriology. It was further cofirmed using 16S rDNA primer. The population of endosymbiont Photorhabdus found less in non cultivated land as compared to cultivated soils of Karnataka.
EARLY BLUE CRAB RECRUITMENT TO ALTERNATIVE NURSERY HABITATS IN MISSISSIPPI, USA

Abstract Although seagrass in the lower segments of estuaries provides good nursery habitat for blue crabs, the role of alternative inshore habitats for early blue crab recruitment is not well-known. Using suction sampling, we examined the recruitment dynamics of early blue crabs (Callinectes spp.) over a 10-wk study period at 7 sites representing potential nursery habitats, including 2 marsh edge sites, 2 subtidal unvegetated sites adjacent to salt marsh, 2 subtidal unvegetated sites adjacent to developed marsh, and 1 upestuary subtidal vegetated site. Abundances of small (<6.0 mm CW) and large (≥6.0 mm) juvenile crabs varied over the study period, mainly reflecting two monthly pulses of small crabs coinciding with the new moon phase. Early crabs were significantly more abundant from structured habitats than from subtidal unvegetated habitat; although small crabs were moderately abundant at subtidal unvegetated sites situated lower in the estuary. Large crabs were not abundant from subtidal unvegetated sites; whereas large crabs were abundant from sites with structured habitat. Subtidal unvegetated sites were characterized by crab size-distributions with single modes representing postsettlement crabs and with few large crabs; whereas structured habitats contained relatively more large crabs. However, crab size-distributions varied among structured habitats. Spatio-temporal variation in the early recruitment dynamics of blue crabs reflected temporal changes, such as lunar periodicity; landscape effects, such as proximity to currents; and habitat effects.
An Assessment of the Theory and Practice of Inclusive Education , with Special Reference to Secondary Teacher Education in Zimbabwe

The purpose of this study was to examine the relevance and effectiveness of the inclusive education programme run by secondary teachers’ colleges in their preparation of student teachers for the challenges of teaching students with diverse learning needs as found in regular secondary schools. An intensive research approach which applied qualitative techniques of data generation was used. The study utilised information from multiple sources such as participants from a purposively selected secondary teacher education institution, key informants from the area of education, and documents from the department that taught inclusive education at the selected college. Data on barriers to learning and achievement of students in secondary schools were generated from what were judged to be information-rich sources, using focus group discussions, and semi-structured interviews. The model used for assessing the inclusive education programme was designed for that purpose, through a combination of two theories: Program Evaluation Theory by Rossi, Lipsey, and Freeman (2004) and Discrepancy Evaluation Model by Provus (1969). The findings of the study revealed that the inclusive education programme run by teachers’ colleges did not take into consideration what was viewed by participants and key informants as barriers to students’ learning and achievement in schools. Based on the findings, the study made a number of recommendations on what strategies could be used by teacher education to develop student teachers for inclusive teaching. The recommendations included the following: that Zimbabwe should reach a point of consensus on the meaning of inclusive education; that barriers to learning experienced by students in the schools should be used to inform inclusive education programmes for teachers’ colleges; and that the teaching of reading should be deliberately factored into all the subject majors in teacher education.
Beryllium and Other Trace Elements in Paragneisses and Anatectic Veins of the Ultrahigh-Temperature Napier Complex, Enderby Land, East Antarctica: the Role of Sapphirine

Anatectic veins containing the Be minerals khmaralite and beryllian sapphirine as primary phases (or surinamite derived therefrom) are associated with Mg–Al-rich paragneisses at three localities in the ultrahigh-temperature Napier complex, Antarctica, a unique Be mineralization in the granulite facies. Likely precursors of the paragneisses are volcaniclastic deposits that were hydrothermally altered by heated seawater prior to metamorphism. Regular distribution of Be among minerals in the paragneisses suggests an approach to equilibrium with Be greatly concentrated in sapphirine (25– 3430 ppm Be) or cordierite (560–930 ppm Be) relative to plagioclase An53–66 (14–43 ppm Be) > cores of coarse-grained orthopyroxene (0 7–29 ppm Be) > coronitic orthopyroxene (0 4– 14 ppm Be) sillimanite (0 1–26 ppm Be) plagioclase An18– 33 (0 6–15 ppm Be) > biotite (0 06–8 ppm Be) > K-feldspar, quartz, garnet (0 05–0 7 ppm Be). Sapphirine-bearing paragneisses have average Be concentrations, 4 9 2 4 ppm (13 samples), about twice that of typical pelites, whereas paragneisses lacking sapphirine and primary cordierite have only 2 9 2 1 ppm Be (12 samples), implying some loss of Be during metamorphism. The likely source rocks for the Be-rich melts were biotitic rocks lacking the Be sinks sapphirine and cordierite. These gneisses were probably less competent than the sapphirine-bearing gneisses, so the melts were drawn to the latter and collected in spaces opened during deformation and boudinage of the more competent paragneisses. Fractionation of the melts concentrated Be to the extent that Be minerals could crystallize. The final result was Be-mineralized anatectic veins hosted by relatively Be-rich sapphirine-bearing paragneisses.
Trailing Edge Noise Reduction Using Novel Surface Treatments

A novel trailing edge noise control technique based on upstream manipulation of large coherent turbulent structures using two dimensional surface treatments has been proposed and tested. To demonstrate the capabilities of the proposed trailing edge noise control technique, a long flat-plate model, equipped with several streamwise and spanwise surface pressure microphones, has been designed and built. Flow and noise measurements have been carried out for a variety of surface treatments, with different geometrical patterns and dimensions. The flow behavior downstream of the surface treatment is also studied by employing a single probe hotwire anemometer. Results have shown that the use of such surface treatments can lead to around 8 dB reduction of the surface pressure fluctuations near the trailing edge. More importantly, it has been observed that the spanwise coherence can be significantly reduced over a wide range of frequencies, implying that the large coherent turbulent structures have been successfully removed from the boundary layer. Furthermore, the unsteady surface pressure and boundary layer velocity cross-correlation studies have shown that the correlation between the turbulent structures within the outer region of the boundary layer and the unsteady surface pressure exerted on the surface can be significantly reduced by using treatments with height of only 10% of the boundary layer thickness
Aptamers: Promising Molecules for Cancer Stem Cell Targeting

The term Cancer Stem Cells (CSCs) has been coined to refer to a subpopulation of tumor cells that has the ability to self-renew and to generate the diverse cell pool of a given tumor. In the last decade CSCs have been receiving a lot of interest due to their cancer initiating and maintaining capabilities making them the real driving force within a malignant mass that pushes towards more aggressive proliferation and more resistance against anticancer drugs. These cells have been linked to different specific markers in an attempt to achieve efficient isolation and characterization. Such markers include CD44, EpCAM and CD133 among others. Aptamers are synthetic single stranded oligonucleotides selected from a huge pool of random sequences which can fold and bind to a wide range of targets with high affinity and specificity. They are not immunogenic or toxic and have good clearance rates, qualities that make aptamers a good rival to monoclonal antibodies in their diagnostic as well as therapeutic applications. This review explores the potential applications of aptamers selected to target the main markers of CSCs. Such applications include diagnostic assays and analytical platforms where such aptamers can be utilized to detect and characterize the behavior of these cells in addition to predicting and monitoring disease course and response to different treatment regimens. The potential therapeutic applications are also discussed in details, where such anti- CSC aptamers can be used in a variety of formulations to efficiently target the initiating cores of tumors.
Parametric Monitoring of Computing Processes in Information and Computing Systems

In recent years, methods based on modeling have been widely used, as well as experimental methods based on measurements of the parameters of real-time ICS systems on solvable problems. A feature of most known approaches and methods of analyzing the CP is the formal consideration of certain processes and events occurring in the system and characterizing it at various stages of functioning at a logical level. Usually in this case, assumptions of various kinds are accepted, which are caused not by the logic of the ICS, but by the specific nature of the applied mathematical apparatus. Obviously, a different approach is required, which is devoid of this shortcoming. Such an approach can be, for example, operational analysis of computer performance. The method of operational analysis is mainly based on the use of ICS models with queues and requires from an analyst the knowledge of the principles of ICS functioning at a logical level. It is allowing to evaluate the integral performance of the system, which is dependent on a large number of parameters and approximately calculated from the results of measurements without the use of ICS means. Based on the results of approximate calculations, the values of the basic indicators of the ICS are determined and then decisions are taken on the organization of the CP. The peculiarity of this approach (i.e. engineering approach) is to consider from the engineer's point of view the structure of the ICS, the processes and events occurring in it, when it is required to decompose the system; to highlight in its complex structure the backbones and directions for which the IS is distributed; to identify the sets of IS’s and parameters that characterize these streams; to establish relationships between threads and their parameters; to develop requirements for the measurement of these parameters; to conduct (by means of measurements) the collection and analysis of statistical data of IS.
Economic and environmental effectiveness of a technology-based climate protocol

Abstract The present stalemate in climate negotiations between the USA and the other Annex I countries has led policy analysts and economists to explore the possible emergence of alternative climate regimes that may be applied after 2012. This article explores the idea of replacing international cooperation on greenhouse gas emission control with international cooperation on climate-related technological innovation and diffusion. This idea—recently proposed among others by Barrett (2001) and Benedick (2001)—is based on the insight that incentives to free-ride are much smaller in the case of technological cooperation than in the case of cooperation on emission control. This article provides a first applied game theory analysis of a technology-based climate protocol by assessing: (i) the self-enforcingness (namely, the absence of incentives to free-ride) of the coalition that would form when countries negotiate on climate-related technological cooperation; (ii) the environmental effectiveness of a technology-based climate protocol. The analysis is carried out by using a model in which endogenous and induced technical change are explicitly modelled. The results of our analysis partly support Barrett's and Benedick's conjectures. On the one hand, a self-enforcing agreement is more likely to emerge when countries cooperate on environmental technological innovation and diffusion than when they cooperate on emission abatement. However, technological cooperation—without any commitment to emission control—may not lead to a sufficient abatement of greenhouse gas concentrations.
Impedimetric Sensors for Bacteria Detection

The application of electrochemical biosensors based on impedance detection has grown during the past years due to their high sensitivity and rapid response, making this technique extremely useful to detect biological interactions with biosensor platforms. This chapter is focused on the use of electrochemical impedance spectro‐ scopy (EIS) for bacterial detection in two ways. On one hand, bacteria presence may be determined by the detection of metabolites produced by bacterial growth involving the media conductivity changes. On the other hand, faster and more selective bacterial detection may be achieved by the immobilization of bacteria on a sensor surface using biorecognition elements (antibodies, antimicrobial peptides, aptamers, etc.) and registering changes produced in the charge transfer resistance (faradic process) or interfacial impedance (nonfaradic process). Here we discuss different types of impedimetric biosensors for microbiological applications, making stress on their most important parameters, such as detection limits, detection times, selectivity, and sensitivity. The aim of the paper was to give a critical review of recent publications in the field and mark the future trends. the selectivity of AMP-functionalized microelectrodes: gram-negative pathogenic E. coli O157:H7, E. coli ATCC 35218, pathogenic S. typhimurium , and gram-positive pathogenic L. monocyto‐ genes . The response of biosensor with magainin I was clear preferential toward pathogenic gram-negative species of E. coli and Salmonella, especially toward E. coli O157:H7, demon‐ strating interbacterial strain differentiation and maintaining recognition capabilities toward pathogenic strains of E. coli and Salmonella. This research also demonstrated antimi‐ crobial peptides self-assembling onto a wireless graphene nanosensor on a tooth for remote monitoring of respiration and bacteria in
Waveguide piezoelectric micromachined ultrasonic transducer array for short-range pulse-echo imaging

This paper presents an 8 × 24 element, 100 μm-pitch, 20 MHz ultrasound imager based on a piezoelectric micromachined ultrasonic transducer (PMUT) array having integrated acoustic waveguides. The 70 μm diameter, 220 μm long waveguides function both to direct acoustic waves and to confine acoustic energy, and also to provide mechanical protection for the PMUT array used for surface-imaging applications such as an ultrasonic fingerprint sensor. The imager consists of a PMUT array bonded with a CMOS ASIC using wafer-level conductive eutectic bonding. This construction allows each PMUT in the array to have a dedicated front-end receive amplifier, which together with on-chip analog multiplexing enables individual pixel read-out with high signal-to-noise ratio through minimized parasitic capacitance between the PMUT and the front-end amplifier. Finite element method simulations demonstrate that the waveguides preserve the pressure amplitude of acoustic pulses over distances of 600 μm. Moreover, the waveguide des.
Modelling the Dynamic Response of a Morphing Wing with Active Winglets

This paper investigates the capabilities of the SimMechanics Simulink multibody modelling tool in analysing the dynamic and shape changing response of morphing aircraft. The research is focused on morphing aircraft that undergo large discrete shape variation in which the “morphing” is due to a set of rigid bodies moving relative to each other. The aerodynamic loads contribution is calculated via a quasi-steady linear vortex-lattice code that has been implemented within the Matlab-Simulink environment in order to be directly linked to the SimMechanics block. The methodology is applied to an actual morphing aircraft demonstrator that is a flying wing based on an “active winglets” concept which means that manoeuvres are controlled by a two degrees of freedom tilting-wing-tip system. Particular attention is given to the effects of the variation in the shape on the inertia properites, the centre of gravity location and modal parameters. Finally a response simulation with respect to a time change in shape input is discussed.
Challenges and Success Criteria for Mobile Services in Tourism

The biggest challenge of providing mobile services in tourism today is to enable small and medium sized institutions and individuals to develop location based content. Major obstacles are high demands on supporting infrastructure and technical expertise. Also the lack of standards in this area hinders a wider and diverse development of new services. Especially locals have the best knowledge of their region and can usually provide more useful and up-todate information for travellers and residents than universal service providers could do. This article discusses success criteria for a portable LBS platforms and authoring tools. The goal is to enable a wide range of local institutions developing their own LBS applications, maintaining their content and protecting their investments.

Coded Wavelet Packet OFDM with Companding for PAPR Reduction

In this paper, coded wavelet packet OFDM with companding is proposed. For the proposed OFDM, at the transmitter PAPR is calculated for different coded tree structures developed and tree with minimum PAPR is selected for transmission. The proposed wavelet packet is advantageous in terms of performance as compared to without coding and companding. Simulation performed for Haar and DB WPT structures with BPSK modulation shows that BER performance is also preserved in addition to minimum PAPR. Haar WP OFDM performance shows 2dB improvement for BER of 0.01 compared to DB4 and PAPR improvement by 4dB.In addition Golay code provides 2db better performance than Hadamard for both Haar and DB4 WP OFDM.
Does Uranium Mining Increase Civil Conflict Risk? Evidence from a Spatiotemporal Analysis of Africa from 1960 to 2008

We investigate whether uranium, similar to other resources, is associated with armed conflicts. The analysis uses grid cells in Africa to test this hypothesis. Results from logistic regressions reveal that uranium operations are not an independent conflict risk; however, it is significantly linked to local conflict events when interacting with ethnic exclusion. The analysis is supplemented by process tracing in four countries, where armed conflict broke out after uranium operations started (DR Congo, Central African Republic, Niger and South Africa). We find substantial evidence for a link only in the case of Niger. Our results suggest that uranium promotes intrastate conflict only under specific circumstances.
Selfish Node Detection in Replica Allocation over MANETs

MOBILE ad hoc networks (MANETs) have attracted a lot of attention due to the popularity of mobile devices and the advances in wireless communication technologies. A MANET is a peer-to-peer multi hop mobile wireless network that has neither a fixed infrastructure nor a central server. Each node in a MANET acts as a router, and communicates with each other. In a mobile ad hoc network, the mobility and resource constraints of mobile nodes may lead to network partitioning or performance degradation. Several data replication techniques have been proposed to minimize performance degradation. Most of them assume that all mobile nodes collaborate fully in terms of sharing their memory space. In reality, however, some nodes may selfishly decide only to cooperate partially, or not at all, with other nodes. These selfish nodes could then reduce the overall data accessibility in the network. In this paper, we examine the impact of selfish nodes in a mobile ad hoc network from the perspective of replica allocation. We term this selfish replica allocation. In particular, we develop a selfish node detection algorithm that considers partial selfishness and novel replica allocation techniques to properly cope with selfish replica allocation. The conducted simulations demonstrate the proposed approach outperforms traditional cooperative replica allocation techniques in terms of data accessibility, communication cost, and average query delay.
Localized histiocytic sarcoma in a captive capybara (Hydrochoerus hydrochaeris)

An irregular, subcutaneous mass (2x3x2 cm) located between the first and second digits of the left hindlimb of a nine-year-old, male, captive capybara (Hydrochoerus hydrochaeris) was biopsied. Microscopically, the mass scattered throughout the dermis. The neoplastic cells were arranged in solid-sheet patterns and comprised of pleomorphic histiocytic cells with pleomorphic nuclei and abundant eosinophillic cytoplasm. Mitotic figures were 2-3 cells/HPF. Numerous, multinucleated, giant cells, up to 10 nuclei/cells, were also prominently observed and found scattered throughout the mass. Immunohistochemically, the neoplastic cells were strongly positive for vimentin and ionized calcium-binding adaptor molecule 1 (Iba-1), while immunoreactivity for cytokeratin was negative. Based on histopathological and immunohistochemical characterizations, localized histiocytic sarcoma was diagnosed.
