Effects of imidacloprid and fenobucarb on the dynamics of the psyllid Diaphorina citri Kuwayama and on the incidence of Candidatus Liberibacter asiaticus

Introduction. The effects of imidacloprid and fenobucarb insecticides on the dynamics of the psyllid Diaphorina citri and on the incidence of Candidatus Liberibacter asiaticus (Ca. L. a.), the putative causal agent of Huanglongbing disease (HLB), were studied in a field experiment. Mate- rials and methods. The experimental design consisted of three independent 0.5-ha Citrus orchards planted with disease-free HLB-susceptible orange trees, located in a Citrus producing area seriously affected by HLB. Imidacloprid was applied monthly to the trunks in one orchard at a rate of 0.15 g a.i.·tree -1 ; fenobucarb was sprayed fortnightly in a second orchard at a rate of 250 g a.i.·ha -1 . The 3rd orchard was managed as a control without insecticide applications. The total number of adult D. citri specimens and the percentages of trees harbouring psyllid eggs and 5th instar nymphs were monitored at fortnightly intervals in each orchard. Ca. L. a. incidence was assessed in each orchard by PCR at 5 months, 12 months and 24 months after planting. Results. Compared with the control, both the fenobucarb and imidacloprid treatments reduced adult psyllid populations by over 90% and reduced the frequency of trees harbouring eggs and 5th instar nymphs. Only imidacloprid treatments totally prevented development of a new generation of adults from eggs. Two years after planting, the prevalence of Ca. L. a. was 0.939, 0.745 and 0.239 in the control and in the orchards treated with feno- bucarb and imidacloprid, respectively. Discussion and conclusion. The results indicated that, althoughboththeinsecticidesusedeffectivelyreducedD.citripopulationsbykillingadultsandnymphs andbyaffectingorpreventingpsyllidreproductioninorchards,neitherofthetwoinsecticidetreatments totally prevented transmission of Ca. L. asiaticus. However, due to its long-lasting effect and systemic activity, the imidacloprid treatment provided the best protection against infections, and delayed and slowed down the spread of the pathogen. Furthermore, it reduced the number of pesticide applications needed and left the way open for biological integrated pest management programmes.

Terrain effect on gravity field parameters using different Terrain models

This paper presents the results of several analyses considering influence of terrain models on gravity field data. In the analysis are used digital elevation model (DEM) made by digitalization of topographic maps, Shuttle Radar Topography Mission Digital Terrain Elevation Data (SRTM DTED), gravity anomalies, GPS\leveling undulations and deflections of the vertical in Croatian geoid test area. To check the influence of different terrain resolutions on residual terrain model (RTM) effects on gravity anomalies and GPS\leveling undulations, the resolutions of referent terrain models 6'x7.6', 10'x15', 20'x30' and 30'x30' are used. Influence of different referent DEM resolutions on remove-restore residual fields is showing the smoothest and smallest field for resolution 20'x30'. The comparison of DEM and SRTM DTED terrain models is made to check their quality. To judge influence on gravity field considering differences of DEM and SRTM DTED terrain models, RTM effects on gravity anomalies, GPS\leveling undulations and vertical deflections are modeled.
Cuckoo Search Algorithm with Chaotic Maps

Cuckoo search algorithm is a novel nature-inspired optimization technique based on the obligate brood parasitic behavior of some cuckoo species. It iteratively employs Levy flights random walk with a scaling factor and biased/selective random walk with a fraction probability. Unfortunately, these two parameters are used in constant value schema, resulting in a problem sensitive to solution quality and convergence speed. In this paper, we proposed a variable value schema cuckoo search algorithm with chaotic maps, called CCS. In CCS, chaotic maps are utilized to, respectively, define the scaling factor and the fraction probability to enhance the solution quality and convergence speed. Extensive experiments with different chaotic maps demonstrate the improvement in efficiency and effectiveness.
Software Synchronization of Projector and Camera for Structured Light 3D Body Scanning

Current 3D body scanners based on structured light principle are expensive and somewhat bulky machines which limits their wider spread. One of the factors driving the scanner cost up is the requirement to synchronize projector and camera which requires either expensive system components a costly customized hardware synchronization solution. We propose a software solution to the projector-camera synchronization problem which enables construction of low-cost 3D scanner using common commercial off-the-shelf components only: a projector, a camera, and a computer. We also propose a simple calibration procedure for precise measurement of delay time which is necessary to achieve proper synchronization. We have developed a prototype system for 3D human body scanning using the proposed approach which achieves projector-camera synchronization and enables data acquisition at 30 FPS.
Transient Detection and Tempo Estimation in Polyphonic Music Signals

Tempo estimation is a subject of intensive research in the field of Music Information Retrieval, as many applications demand the automatic induction of the tempo of musical excerpts. In such applicationsit is desired that a correct tempo estimation would be available to the system at about the same time that the tempo is detected by a human listener. This is technically very difficult because the human listeners are able to use higher level context cues to conduct tempo detection. In fact, many algorithms proposed for tempo detection in the past require a long signal segment for reliable results in tempo estimation. This is clearly a problem in contents such as radio programs, where the rhythmic music content may alternate with, for example, speech segments. There is a wide range of literature methods related to the topic of tempo estimation. So far, tempo estimation systems follow a general scheme that consists of two main steps. In the first step, a feature list is created which is used in the second step in order to detect recurrences of certain events in it. Many different approaches have been proposed in the past for the implementationof the above stages. In this thesis, a new approach to the implementation of the first step is proposed, along with the addition of a final step that will enhance the whole tempo estimation procedure. The proposed method for the extraction of the feature list is based ontransient detection. The term transient is used to describe these points in the time representation of the input signal where abrupt changes take place in its amplitude. The detection is conducted using Gammatone subspace analysis and adaptive Linear Prediction Error Filters. The transient detection function produced from this processing is further processed resulting to the necessary feature list. After the second step, where the feature list is fed as an input to a bank of comb filters resonators, the application of a model that approximates the tempo perception by human listeners is proposed. The later will enhance the results of tempo estimation with perceptual information. The evaluation of the proposed system is done using accuracy measures and musical excerpts obtained from the ISMIR 2004 Tempo Induction Evaluation Exchange benchmark corpus, also used from the first ever attempt to conduct systematic comparison of tempo estimation systems. The results of the evaluation indicate that the proposed method compares favourably with other, state-of-the-art tempo estimation methods, using only one frame of the musical excerpts when most of the literature methods demand the processing of the whole piece.
Mixed Effects Models with Censored Covariates, with Applications in HIV/AIDS Studies

Mixed effects models are widely used for modelling clustered data when there are large variations between clusters, since mixed effects models allow for cluster-specific inference. In some longitudinal studies such as HIV/AIDS studies, it is common that some time-varying covariates may be left or right censored due to detection limits, may be missing at times of interest, or may be measured with errors. To address these “incomplete data“ problems, a common approach is to model the time-varying covariates based on observed covariate data and then use the fitted model to “predict” the censored or missing or mismeasured covariates. In this article, we provide a review of the common approaches for censored covariates in longitudinal and survival response models and advocate nonlinear mechanistic covariate models if such models are available.
Study of Alkali Metal Corrosion on Heating Surfaces and Bed Material Agglomerate in Biomass-fired Fluidized Bed Boiler

The bed material agglomeration and heating surface high-temperature Corrosion Problems of biomass-fired boiler in South China were studied in this work. The inner and outer surfaces of the corrosion sample were investigated by scanning electron microscope (SEM) with Bruker EDX and XRD. Results showed that the outer side of the corrosion sample was mainly composed of alkali chloride deposited ash, sulphide and a small amount of eutectoid; while the inner side of the corrosion sample was still mainly made up of the composition of SUS316, but added with alkali metal, oxygen, chlorine and sulphur elements, appearing as the corrosion products and eutectoid. It was thought that alkali chloride deposit and the reaction with pipe metal to generate low melting point eutectoid on the outer surfaces, or the corrosion reaction through the alkali metal sulphatization process was the main reasons leading to the damage of metal surface oxide film. Chlorine plays a role as haptoreaction in the corrosion process, and transports metal material as the form of chloride from the inner side to the outer side of the pipe surfaces by diffusion, accelerating the corrosion process. Meanwhile, the slag was studied by scanning electron microscope (SEM) with Bruker EDX, and the transformation process of slage was computationally analyzed by FACTSAGE. Results showed that the amount of alkali metal in the agglomerates was little, however, caused a great impact on severe agglomerates. The increase of temperature enhanced the conversion process of alkali metal to molten oxide, especially when the temperature was higher than760℃, the amount of molten product increased sharply. Thus, the temperature control of fluidized bed plays an important role in solving the problem of alkali metal agglomerates; it also reliefs the volatile of alkali metal into gas phase, benefiting the control of heating surface corrosion.
Development and Design of a 340 GHz Photomixer Source

We present the design of an InGaAlAs/InP uni-traveling-carrier photo-diode (UTC-PD) at mm-wave frequencies up to 340 GHz. The photo diode epitaxy is optimized using a quasi-3D software implementing the hydrodynamic semiconductor equations, for which an output power of 3 mW at 340 GHz was simulated. An equivalent circuit of the UTC-PD has been fitted to experimental S11 measurements up to 67 GHz. Finally, an optimized antenna coupled UTC-PD with choke filter has been designed. This MMIC circuit is intended for photomixing, with output power at 340 GHz.
Attention to Mathematical Structure during Participation in a Mathematics Classroom Task by Learners of English as an Additional Language (EAL).

How do students who are learning English as an additional language (EAL) participate in classroom mathematics? To investigate this question, I collected recordings of primary school EAL students as they worked with peers on a mathematics classroom task. Drawing on theoretical and methodological work in discursive psychology (Edwards, 1997), I analysed students’ interaction and identified several patterns of attention, including a pattern of attention to mathematical structure. In this paper I report how the students in the study used attention to mathematical structure as part of their joint work on the task. My analysis shows how EAL students are able to participate successfully in mathematics classroom interaction. My analysis also highlights the social nature of this interaction.
Anatomical study of Racosperma (ex-Acacia) mangium tissues cultured in vitro

In order to achieve adventitious shoot regeneration from young tissues of Racosperma mangium, several combinations of growth regulators were tested. Kinetin (KIN) and a -naphthalenacetic acid (NAA), thidiazuron (TDZ) and NAA or indole-3-butyric acid (IBA), 4-CPPU and 2,4-dichlorophenoxyacetic acid (2,4-D) were added to basic medium composed of MS salts, MS vitamins and 3% sucrose. Sections of hypocotyls and cotyledons of young seedlings were cultivated on these media. Calli developed on different media and, after two to three months, some of them regenerated organized structures. Histological studies revealed hypertrophy and hyperplasy of medular and cortical parenchyma cells of hypocotyl and cotyledon parenchyma. Formation of meristematic cells and traqueary elements from parenchyma was observed during in vitro culture. In some cases, nodules of traqueary elements were formed. The highest differentiation into meristematic cells was found in cotyledon tissues cultured on 4-CPPU (8.07 µM) and 2,4-D (1.13 µM).

Ichthyofaunal Diversification and Distribution in the Big Creek Watershed, Craighead and Greene Counties, Arkansas

Big Creek is a relatively small deltaic stream, in northeastern Arkansas, in an area of intense cultivation. Recently ithas been dredged in the interest of flood control. Lost Creek and Mud Creek are the major tributaries of Big Creek and collectively drain the Big Creek watershed. The streams were found to have relatively low alkalinity, moderate carbon dioxide, adequate oxygen values, and relatively high turbidity. Channeling of Big Creek and Lost Creek has effectively destroyed distinct pool-riffle biocies and reduced the number of acceptable spawning areas. Lost Creek, also, receives effluent from residential dwellings, a secondary treatment sewage plant, and a meat rendering plant. Mud Creek, in the absence of channeling and deleterious effects of effluents, provided a relatively greater diversity of habitat than did Big Creek or Lost Creek. tA total of 21 species were collected in the streams. Big Creek supported 17 species while Mud Creek and Lost c supported 14 and 11 species, respectively. Five of the 11 species collected in Lost Creek are characteristic reams with plentiful organic debris and were not collected, in numbers, at any other station in the watershed. the 2,209 fishes collected, Notropis umbratilis, Fundulus olivaceous, and Leomis cyanellus made up 63% b total and were procured from all sations. Their relative abundance is supported by their ability to withstand turbidity and limited competition due to depth effect. iLimited species included Ictalurus natalis, Aphredoderus sayanus, and Etheostoma gracile in Mud Creek; Dorcepedianum in Lost Creek; and the headwater species, Semotilus atromaculatus, in Big Creek and Mud Creek. nus carpio, Ictalurus melas, Gambusia affinis, and Notemigonus crysoleucas were also limited, in relative numbers, to Lost Creek.
Are white-beaked dolphins Lagenorhynchus albirostris food specialists? Their diet in the southern North Sea

The white-beaked dolphin Lagenorhynchus albirostris is the most numerous cetacean after the harbour porpoise Phocoena phocoena in the North Sea, including Dutch coastal waters. In this study, the diet of 45 white-beaked dolphins stranded on the Dutch coast between 1968 and 2005 was determined by analysis of stomach contents. Although 25 fish species were identified, the diet was dominated by Gadidae (98.0% by weight, 40.0% in numbers), found in all stomachs. All other prey species combined contributed little to the diet by weight (2.0%W). The two most important prey species were whiting Merlangius merlangus (91.1% frequency of occurrence (FO), 30.5%N, 37.6%W) and cod Gadus morhua (73.3%FO, 7.4%N, 55.9%W). In numbers, gobies were most common (54.6%N), but contributed little to the diet by weight (0.6%W). Three stomachs contained different prey compared to the others: one animal had taken 2250 gobies, accounting for 96.4% of all gobies found; one animal had fed on 29 small sepiolids; and one animal had solely taken haddock Melanogrammus aeglefinus. Squid and haddock were not found in any other stomach. The overall diet showed a lasting predominance of whiting and cod, without clear changes over time (35 years) or differences between sexes or size-classes of dolphins. This study adds to earlier published and unpublished data for Dutch coastal waters and agrees well with studies of white-beaked dolphins from other parts of the species’ range, in the North Sea and in Canadian waters, with Gadidae dominating the diet on both sides of the Atlantic.
Evaluation of High Speed Hardware Multipliers - Fixed Point and Floating point

There is a huge demand in high speed arithmetic blocks, due to increased performance of processing units. For higher frequency clocks of the system, the arithmetic blocks must keep pace with greater requirement of more computational power. Area and speed are usually conflicting constraints so that improving speed results mostly in larger areas. In our research we will try to determine the best solution to this problem by comparing the results of different multipliers. Different sized of two algorithms for high speed hardware multipliers were studied and implemented ie. Parallel multiplier, Bit serial multiplier. The workings of these two multipliers were compared by implementing each of them separately in VHDL. A number of high speed adder designs are developed and algorithm and design of these adders are discussed. The result of this research will help us to choose the better option between serial and parallel multipliers for both fixed point and floating point multipliers to fabricate in different systems. As multipliers form one of the most important components of many systems, analysing different multipliers will help us to frame a better system with area and better speed.

3D Microstructure Reconstructions of Solid Oxide and Proton Exchange Membrane Fuel Cell Electrodes with Applications to Numerical Simulations of Reacting Mixture Flows Using LBM

Computational modeling of fuel cell electrode-catalyst layers is an important tool in understanding the different electrochemical reactions and transport phenomena occurring within fuel cell electrodes. Proper modeling of this layer is required for an accurate prediction of cell behavior which in turn can be used for the development of more efficient fuel cells. In macroscopic CFD approaches such layers are typically modeled as infinitely thin interfaces populated by sources and sinks or as very thin homogeneous porous layers. However, these layers are neither infinitely thin nor homogeneous and, thus, modeling in this fashion leads to a loss of information about the microstructure and its varying effects on the reacting mixture flows which pass through and into the structure. Thus, the utility of relying only on such macroscopic representations limits the general applicability of these macroscopic models as tools for design and for predicting fuel cell performance over a wide range of conditions. Furthermore, such macroscopic models cannot aid in the design of the electrode-catalyst layer itself. In order to address this latter point, a microscopic/mesoscopic modeling approach can be used, e.g., the Lattice Boltzmann Method (LBM), which models the reacting mixture flow through the porous microstructure of the electrode-catalyst layer. However, to do so requires reconstructing the porous geometry of this layer which can be done by using 2D microscopic images of cross-sections of the layer to generate 3D geometries from, for example, stochastic models which are relatively cost efficient and lead to similar structures with approximately the same characteristics of porosity, catalyst loading, three-phase boundaries, etc. as the original structure. Two such 3D reconstruction methods, i.e. one based on the granulometry law (one-point statistics) and the other on two-point statistics, are applied to a 2D SEM (scanning electron microscope) image of an SOFC electrode-catalyst layer and to the 2D SEM and TEM (transmission electron microscope) images for such a layer in a PEMFC. Results for these reconstructions are presented as are results for reacting mixture flow simulations through the two different reconstructed 3D SOFC structures using a 3D LBM approach. The development and application of a 3D LBM model for two-phase reacting mixture flows in PEMFC electrode-catalyst layer structures is in progress and will be reported in a future paper.Copyright © 2007 by ASME
Gender Inequality and Economic Growth in Spain: An Exploratory Analysis

This paper compares the geometric variant of the Gender-Related Development Index with that of the Human Development Index for Spanish provinces (EUROSTAT Nomenclature of Territorial Units for Statistics-3, NUTS-3) in 1959, 1981, and 1999. The main objective is to carry out an exploratory analysis of the relationship between these indices and two alternative indices of gender inequality--the Relative Status of Women and the Gender Inequality Index. An analysis of the relationship between these indices and economic growth at the provincial level is also conducted.
