Reaction of Leucaena to Australian populations of root-knot nematode (Meloidogyne spp.)

A nematode tentatively identified from its perineal pattern as Meloidogyne arenaria was found in a planting of Leucaena leucocephala at Crows Nest, Queensland. This is the first report of root-knot nematode on Leucaena in Australia. Further characterisation of the nematode using a standard differential host test confirmed its identity as M. arenaria race 2. Since most previous reports had suggested that Leucaena is resistant to Meloidogyne spp. , L. diversifolia and L. leucocephala cw. Cunningham and Peru were tested in a glasshouse for their capacity to host Australian populations of M. javanica, M. incognita, and M. arenaria. L. diversifolia was susceptible to all species tested whereas L. leucocephala was resistant to M. javanica and M. incognita and susceptible to M. arenaria.
Drivers for Improving Supply Chain Performance: An Empirical Study

A lot of innovation happening nowadays is not so much in the products as in the processes. The importance of integrated, globally optimised supply chains is well understood. Executives have discovered the impact on business performance that can be achieved by effectively managing their supply chains. Nevertheless, a recent study shows that only a fraction of today's supply chains are managed efficiently. One important reason is the mounting challenges faced by executives. These include globalisation and outsourcing, a significant increase in supply and demand uncertainties, more products with short life cycles and the proliferation of products in today's markets. We will identify measures to characterise the business performance as well as supply chain effectiveness and develop measures to characterise the level of maturity of the business process and the information technology employed by a company. Our objective in this research is to identify enablers that allow companies to manage their supply chains so as to maximise business performance. We focus on two classes of enablers: business processes and information technology.
The Efficiency Implications of Corruption

Corruption has different efficiency effects across countries. Conventional economic models of corruption are shown to be deficient in explaining these differences. Instead the article suggests that the distribution of power within the patron-client networks in which corruption is taking place is an important variable explaining the differences in the efficiency effects of corruption. Where patrons are powerful the range of rights transacted is limited and the allocation is likely to be efficiency maximizing. In contrast where patrons are weak the range of rights transacted is likely to be much wider with the rights allocated according to political calculations with large efficiency costs.
Role of Serum Hepcidin levels in the Diagnosis of Iron Deficiency Anemia in Children in Saudi Arabia

Hepcidin, produced in the liver, is a key regulator of systemic iron metabolism. This study aimed to estimate the significance of hepcidin for diagnosis of iron deficiency anemia (IDA) among children and to determine whether routine hematological parameters and iron profile correlate with hepcidin levels in children in Saudi Arabia. Blood samples from children were analyzed for hematology parameters, iron profile and hepcidin-25. A total of 128 children were classified according to hemoglobin level and iron parameters as: IDA (N=97; mean age 5 ±3.5 years) and normal control (N=31; mean age 5.5 ±3.2 years). Significantly lower levels of hemoglobin (p=0.003), serum iron (p=0.001), serum ferritin (p=0.001), transferrin saturation (p=0.002), and hepcidin-25 (p= 0.002) were obtained in children with IDA as compared to normal control group. Significantly high levels of total iron binding capacity (p=0.002) were noted in IDA group. Positive correlation was observed between hepcidin-25 and serum ferritin (r=0.660), serum iron (r=0.374), transferrin saturation (r=0.317) and hemoglobin levels (r=0.246). Low levels of serum hepcidin are significantly associated with lower iron parameters in children, and could be useful indicator of IDA.
A Bayesian method of sample size determination with practical applications

Summary. The problem motivating the paper is the determination of sample size in clinical trials under normal likelihoods and at the substantive testing stage of a financial audit where normality is not an appropriate assumption. A combination of analytical and simulation‐based techniques within the Bayesian framework is proposed. The framework accommodates two different prior distributions: one is the general purpose fitting prior distribution that is used in Bayesian analysis and the other is the expert subjective prior distribution, the sampling prior which is believed to generate the parameter values which in turn generate the data. We obtain many theoretical results and one key result is that typical non‐informative prior distributions lead to very small sample sizes. In contrast, a very informative prior distribution may either lead to a very small or a very large sample size depending on the location of the centre of the prior distribution and the hypothesized value of the parameter. The methods that are developed are quite general and can be applied to other sample size determination problems. Some numerical illustrations which bring out many other aspects of the optimum sample size are given.
Enhanced nonlinear properties of photonic crystal nanocavities

Photonic crystal cavities in silicon-on-insulator platforms have been designed to achieve very high quality factors and/or far-field input/output coupling. In this paper I will review our works on the use of these cavities to realize: record-high-Q resonators by genetic optimization of the holes, and bright light emission in an electrically pumped light-emitting diode. Finally, I will discuss theoretical predictions for the realization of quantum photonic devices, such as single-photon sources and diodes, in all-silicon or hybrid photonic crystal platforms.
SUGAR BEET PRODUCTION AFTER PREVIOUS CROPS OF CORN, WHEAT, AND SOYBEAN

Sugar beet production has typically followed a small grains crop, such as hard red spring wheat (HRSW) in the Red River Valley (RRV) of Minnesota and North Dakota. However, in the southern part of the RRV and in the Southern Minnesota Beet Sugar Cooperative growing area, sugar beet production generally follows a previous crop of corn. Sims (2004) reported corn residue had a negative effect on sugar beet yield, but that effect appeared not to be related to nitrogen (N) availability. Following a typical HRSW crop, wheat residue had minimal or no effect on the following year’s sugar beet root yield and quality. Corn production is expected to increase in sugar beet growing areas north of Fargo. Growers have raised concerns about the negative effects of the corn residue and have asked if managing the corn residue with a moldboard plow instead of a chisel plow would reduce this negative effect. Another crop that has increased in acreage in sugar beet growing areas is soybean. Currently, it is not recommended that sugar beet be grown after a previous crop of soybean. Previous research in the RRV showed reductions in both sugar beet root yield and quality (recoverable sucrose per ton of beet) when grown after soybean compared to grown after a small grain crop (Smith and Dexter, 1988). However, Soine and Severson (1975) and Nordgaard et al., (1982) found no or, perhaps, a positive effect of a previous crop of soybean on sugar beet root yield and quality. Soybean production is expected to increase in the northern sugar beet growing area of Minnesota and North Dakota. Furthermore, this increased soybean production will likely displace small grains production. Thus the likelihood that sugar beet will be grown after a previous crop of soybean will increase in the future. The current trial was established to examine the combined effects of previous crop, primary tillage of the previous crop, and N management of the following sugar beet crop. More specific objectives are:
Spacecraft telemetry data monitoring by dimensionality reduction techniques

In this paper, we consider a "data-driven" anomaly detection framework for spacecraft systems using dimensionality reduction and reconstruction techniques. This method first learns a mapping from the original data space to a low dimensional space and its reverse mapping by applying linear or nonlinear dimensionality reduction algorithms to a normal training data set. After the training, it applies the learned pair of mappings to a test data set to obtain a reconstructed data set, and then evaluate the reconstruction errors. We will show the results of applying several representative linear and nonlinear dimensionality reduction algorithms with this framework to the electrical power subsystem (EPS) data of actual artificial satellites.
The Australian sport system and its stakeholders: development of cooperative relationships

The way the Australian sport system arrested its unrelenting decline in the 1970s to become a model of best practice perplexes many countries. This essay aims to give an insight into the way the system was transformed and became successful. The essay reviews the decline, and then the evolution and devolution of the system, and analyses the stakeholders involved, and the inter relationships developed to achieve success. The study is based on a document analysis examining 74 annual reports from 35 national sporting organizations over a period of four years, before and after the Sydney Olympic Games. The results of the study show that in the face of financial instability and an over-reliance on government funding, sport stakeholders sought alternative sources of income, amalgamated or worked in collaboration with other stakeholders, and/or opted for intra-organizational cooperation. The sport system in Australia has proven resilient and able to adapt to an ever-changing environment via the cooperation of its stakeholders and their willingness to work together towards a common goal.
Neutron diffraction study of the magnetic and structural phase transitions in BaFe2As2

We present the results of an investigation of both the magnetic and structural phase transitions in a high quality single crystalline sample of the undoped, iron pnictide compound BaFe$_2$As$_2$. Both phase transitions are characterized via neutron diffraction measurements which reveal simultaneous, continuous magnetic and structural orderings with no evidence of hysteresis, consistent with a single second order phase transition. The onset of long-range antiferromagnetic order can be described by a simple power law dependence $\phi(T)^2\propto(1-\frac{T}{T_N})^{2\beta}$ with $\beta=0.103\pm0.018$; a value near the $\beta=0.125$ expected for a two-dimensional Ising system. Biquadratic coupling between the structural and magnetic order parameters is also inferred along with evidence of three-dimensional critical scattering in this system.
Production, Purification, and Characterization of Thermostable Alkaline Xylanase From Anoxybacillus kamchatkensis NASTPD13

Anoxybacillus kamchatkensis NASTPD13 used herein as a source for thermostable alkaline xylanase were isolated from Paudwar Hot Springs, Nepal. NASTPD13 cultured at 60°C, pH 7 and in presence of inorganic (ammonium sulfate) or organic (yeast extract) nitrogen sources, produced maximum xylanase enzyme. Xylanase production in the cultures was monitored by following the ability of culture media to hydrolyze beech wood xylan producing xylooligosaccharide and xylose by thin layer chromatography (TLC). The extracellular xylanase was isolated from optimized A. kamchatkensis NASTPD13 cultures by ammonium sulfate (80%) precipitation; the enriched xylanase preparation was dialyzed and purified using Sephadex G100 column chromatography. The purified xylanaseshowed 11-fold enrichment with a specific activity of 33 U/mg and molecular weight were37 kDa based on SDS-PAGE and PAGE-Zymography. The optimum pH and temperature of purified xylanase was 9.0 and 65°C respectively retainingmore than 50% of its maximal activity over a broad range of pH (6–9) and temperature (30–65°C). With beech wood xylan, the enzyme showed Km 0.7 mg/ml and Vmax 66.64 μM/min/mg The xylanase described herein is a secretory enzyme produced in large quantities by NASTPD13 and is a novel thermostable, alkaline xylanase with potential biotechnological applications.
Self Scheduling of Plug-In Electric Vehicle Aggregator to Provide Balancing Services for Wind Power

This paper focuses on the self-scheduling problem of an aggregator of plug-in electric vehicles (PEVs) purchasing energy in the day-ahead market, and offering balancing services for a wind power producer, i.e., committing to compensate the forecast errors of wind power plants. The aggregated charging and discharging flexibility of the PEV fleet is represented by a probabilistic virtual battery model, accounting for the uncertainty in the driving patterns of PEVs. Another source of uncertainty is related to the balancing requests, which are a function of the forecasted wind power output. A scenario-based robust approach is used to tackle both sources of uncertainty in a tractable way. The interdependency between the day-ahead market prices and the aggregator's bidding decisions is addressed using complementarity models. A case study analyzes the capability of the PEV aggregation to provide balancing services, for different settings of the balancing contract, and both with and without the use of vehicle-to-grid.
Properties of fi eld-sprouted sorghum and its performance in ethanol production q , qq

The objective of this research was to investigate physicochemical and biochemical characteristics of fieldsprouted grain sorghum and its fermentation performance in ethanol production. Five field-sprouted grain sorghum varieties, which received abnormally high rainfall during harvest, were used in this study. Enzyme activities, microstructure, flour pasting properties, kernel hardness, kernel weight, kernel size, flour size and particle distribution of field-sprouted grain sorghum were analyzed. The effect of germination (i.e., sprouting) on conversion of grain sorghum to ethanol was determined by using a laboratory dry-grind ethanol fermentation procedure. Sprouted sorghum had increased a-amylase activity; degraded starch granules and endosperm cell walls; decreased kernel hardness, kernel weight, kernel size, and particle size; and decreased pasting temperature and peak and final viscosities compared with non-sprouted grain sorghum. The major finding is that the time required for sprouted sorghum to complete fermentation was only about half that of non-sprouted sorghum. Also, ethanol yield from sprouted sorghum was higher (416e423 L/ton) than that from non-sprouted sorghum (409 L/ton) on a 14% moisture basis. 2010 Elsevier Ltd. All rights reserved.
Instability of Democracy as Resource Curse

We suggest a dynamic game theoretic model to explain why resource abundance may lead to instability of democracy. Stationary Markov perfect equilibria of this game with four players – Politician, Oligarch, Autocrat and Public (voters) – are analyzed. Choosing a rate of resource rent tax, potential Autocrat competes with conventional Politician for the office, and Oligarch, the owner of the resource wealth, bribes Politician to influence her decisions. Actual Autocrat's tax policy may be different from the announced one. If the difference is large, then Public may revolt or Oligarch may organize a coup to throw Autocrat down. It is shown that the probability of democracy preservation is decreasing in the amount of resources if the institutional quality is low enough. It does not depend on the amount of resources, if the institutional quality is higher than a threshold. The level of the threshold, however, depends positively on the resource wealth. We have found also that under very low institutional quality, a paradoxical effect takes place: the probability of democracy preservation may decrease with small improvements of institutional quality. It is shown as well that Oligarch earns larger part of rent under democracy than under autocracy. This result conforms to empirical observation which is demonstrated in the paper: under low quality of institutions, democratization leads to higher inequality and inequality entails worsening of the attitude to democracy.
Mercury and Methyl Mercury in Sediments of Northern Lakes-Egypt

Fifty-four sediment samples of the five Northern Egyptian lakes, (Mariout, Edku, El-Burullus, El-Manzallah, and El-Bardaweel) were analyzed to investigate the pollution status of mercury (Hg). The total mercury (T-Hg) content in sediment samples ranged from 15.33 to 171.29 ng·g–1 dry wt). The results showed that T-Hg were lower than the back ground values reported and also lower than the ranges of uncontaminated sediments. Moreover, the T-Hg concentrations in all sediments were under the upper chemical Exceedance level (1 ug·g–1). The concentrations of Methyl mercury (MeHg) in surface sediments of the Northern lakes ranged from 0.002 - 0.023 ng·g–1 dry wt. The contribution of MeHg was less than 0.1% of total mercury concentration with index values from 0.08 - 1.37 ng·g–1; dry wt). MeHg showed insignificant correlation with T-Hg. This suggested that MeHg contents were not controlled by the T-Hg in sediments. The T-Hg and MeHg concentrations were insignificantly correlated with TOC content which indicates that the concentration of T-Hg and MeHg in sediments of Northern lakes were not influence by TOC. The average T-Hg concentration was found in the following order; Mariout > El-Manzallah > El-Burullus > Edku > El-Bardaweel. While the MeHg was found in the order; El-Bardaweel > El-Burullus ≥ El-Manzallah > Mariout > Edku.
Microtubule and F-actin dynamics at the division site in living Tradescantia stamen hair cells

We have visualised F-actin and microtubules in living Tradescantia virginiana stamen hair cells by confocal laser scanning microscopy after microinjecting rhodamine-phalloidin or carboxyfluorescein-labelled brain tubulin. We monitored these components of the cytoskeleton as the cells prepared for division at preprophase and progressed through mitosis to cytokinesis. Reorganisation of the interphase cortical cytoskeleton results in preprophase bands of both F-actin and microtubules that coexist in the cell cortex, centred on the site at which the future cell plate will fuse with the parent cell wall. The preprophase band of microtubules is formed from microtubules that polymerise and incorporate tubulin during prophase. The preprophase band of actin may form either by reorganisation of pre-existing filaments or by de novo polymerisation. Both cytoskeletal components disappear from the future division site approximately five minutes prior to the breakdown of the nuclear envelope. Cortical microtubules are undetectable throughout mitosis and cytokinesis, whereas cortical F-actin remains abundant, although it is notably excluded from the division site. The phragmoplast, containing both F-actin and microtubules, expands towards the cortical actin exclusion-zone through a region that has no detectable microtubules or F-actin. The phragmoplast comes to rest in the predefined region of the cortex that is devoid of F-actin. It is proposed that cortical F-actin may act as a “negative” template which could position the phragmoplast and cell plate correctly. This is the first in vivo documentation of F-actin dynamics at the division site in living plant cells. Summary

Array-Fed Partially Reflective Surface Antenna With Independent Scanning and Beamwidth Dynamic Control

In this communication we present a concept of a partially reflective surface (PRS) antenna capable of independent beam-scanning and beamwidth dynamic control. The beamwidth is controlled by reconfiguring the PRS reflectivity via embedded varactor diodes, while the beam is steered by using a small phased array in the H-plane as a source antenna exciting the Fabry-Pérot cavity. A fully operational prototype is fabricated and measured upon reconfiguration, demonstrating the viability of the concept and good agreement between simulated and measured results. The achieved beamwidth variation is from 18.7° to 22.4°, with the scanning range of 15° and 20° for the narrowest and the widest beamwidth, respectively.
