Differential expression of ozone-induced gene during exposures to salt stress in Polygonum sibiricum Laxm leaves, stem and underground stem

The response of plants to environmental stresses is characterized by a number of physiological and biochemical changes that ultimately result from the selective increase or decrease in the biosynthesis of a large number of distinct proteins. In this report, we describe the characterization of an ozoneinduced transcript, PcOZI-1 , which has been identified from Polygonum sibiricum Laxm by the rapid amplification of cDNA ends method (RACE). PcOZI-1 mRNA in untreated plants was detected at low levels in underground stem, leaves and at higher levels in stem. PcOZI-1 mRNA accumulation was transiently induced in stem 7-fold within the first 8 h of 3% NaHCO3 treatment. PcOZI-1 mRNA accumulation was also induced 22-fold in underground stem after 72 h. Sequence analysis of PcOZI-1 revealed that it encodes a 8.45 kDa basic protein that contains a putative signal peptide. Our results suggest that PcOZI-1 represents a novel stress-related protein that accumulates in response to the production of active oxygen species .

EFFECT OF PRICING STRATEGIES ON COMPETITIVE ADVANTAGE OF SELECTED CEMENT MANUFACTURING FIRMS IN KENYA

The main purpose of the study was to establish the effect of pricing strategies on competitive advantage among firms in cement industry in Kenya. The study was informed by Capability-Based theory. The study utilized an explanatory method and employed quantitative approaches. The target population encompassed a total 553 employees and 5 departmental heads from 5 cement manufacturing firms (Commercial Manager, Finance manager, Safety Health and environmental Manager, Manufacturing Manager. The study used stratified and simple random sampling to select a sample size of 226 employees who were selected as an adequate representation. The study used questionnaires to collect primary data. Quantitative data was analyzed using descriptive statistical techniques which included frequencies, means, and standard deviations. Inferential statistics such as Pearson Product Moment correlations were used to establish the relationships between the variables. Multiple regressions were used to establish the cause effect relationship. The findings showed that value-based pricing strategy had a positive and significant effect on competitive advantage of selected manufacturing firms in Kenya, β 1 = 0.214, p = 0.001. In addition, competition-based pricing strategy had a positive and significant effect on competitive advantage, β 2 = 0.302, p < 0.001. The study was of great importance to cement companies in Kenya as it provided insight into best pricing strategy that could enhance competitive advantage and also challenges encountered and how such strategies were affecting organizational performance. The study helped the government and its policy making agencies as it served as a guide to policy makers on existing pricing strategy among research agencies and difficulties confronted in executing the pricing strategy.

High Resolution Model Intercomparison Project (HighResMIP v1.0) for CMIP6

Abstract. Robust projections and predictions of climate variability and change, particularly at regional scales, rely on the driving processes being represented with fidelity in model simulations. The role of enhanced horizontal resolution in improved process representation in all components of the climate system is of growing interest, particularly as some recent simulations suggest both the possibility of significant changes in large-scale aspects of circulation as well as improvements in small-scale processes and extremes. However, such high-resolution global simulations at climate timescales, with resolutions of at least 50 km in the atmosphere and 0.25° in the ocean, have been performed at relatively few research centres and generally without overall coordination, primarily due to their computational cost. Assessing the robustness of the response of simulated climate to model resolution requires a large multi-model ensemble using a coordinated set of experiments. The Coupled Model Intercomparison Project 6 (CMIP6) is the ideal framework within which to conduct such a study, due to the strong link to models being developed for the CMIP DECK experiments and other model intercomparison projects (MIPs). Increases in high-performance computing (HPC) resources, as well as the revised experimental design for CMIP6, now enable a detailed investigation of the impact of increased resolution up to synoptic weather scales on the simulated mean climate and its variability. The High Resolution Model Intercomparison Project (HighResMIP) presented in this paper applies, for the first time, a multi-model approach to the systematic investigation of the impact of horizontal resolution. A coordinated set of experiments has been designed to assess both a standard and an enhanced horizontal-resolution simulation in the atmosphere and ocean. The set of HighResMIP experiments is divided into three tiers consisting of atmosphere-only and coupled runs and spanning the period 1950–2050, with the possibility of extending to 2100, together with some additional targeted experiments. This paper describes the experimental set-up of HighResMIP, the analysis plan, the connection with the other CMIP6 endorsed MIPs, as well as the DECK and CMIP6 historical simulations. HighResMIP thereby focuses on one of the CMIP6 broad questions, “what are the origins and consequences of systematic model biases? ”, but we also discuss how it addresses the World Climate Research Program (WCRP) grand challenges.
Closure approximations for the Doi theory: Which to use in simulating complex flows of liquid-crystalline polymers?

The goal of this article is to determine which closure model should be used in simulating complex flows of liquid-crystalline polymers (LCPs). We examine the performance of six closure models: the quadratic closure, a quadratic closure with finite molecular aspect ratio, the two Hinch–Leal closures, a hybrid between the quadratic and the first Hinch–Leal closures and a recently proposed Bingham closure. The first part of the article studies the predictions of the models in homogeneous flows. We generate their bifurcation diagrams in the (U,Pe) plane, where U is the nematic strength and Pe is the Peclet number, and place special emphasis on the effects of the flow type. These solutions are then compared with the “exact solutions” of the unapproximated Doi theory. Results show the Bingham closure to give the best approximation to the Doi theory in terms of reproducing transitions between the director aligning, wagging and tumbling regimes at the correct values of U and Pe and predicting the arrest of period.
Phytochemical investigation and in-vitro antioxidant potential of leaves of Murraya koenigii

Murraya koenigii commonly known as curry patta is widely distributed in Uttarakhand (North Indian state) but remains underutilized. The present study has been carried out to evaluate antioxidant potential of Murraya koenigii leaves growing in this region & correlate it with the presence of polyphenols. Methanol, Aqueous and sub-fractions of methanol extract were prepared. Total phenolics, flavonoids and condensed tannins have shown their presence in both methanol and aqueous extracts. TPC and flavonoids were significantly more (p<0.05) in methanol extract. Among the sub-fraction of methanol extract, ethyl acetate fraction has shown the maximum concentration of TPC (170.7µg GAE/mg of extract) as well as of condensed tannin (110µg CE/mg of extract). Crude methanolic extract has shown best DPPH scavenging activity (EC50-0.187mg) when compared with BHT standard (EC50-0.59mg). β-carotene bleaching assay of ethyl acetate fraction of methanol extract has potent antioxidant activity (77.8%; BHT -74.1%) at 1mg/ml concentration. The reducing power of methanol extract (0.273±0.004) and its ethyl acetate fractions (0.239±0.013) is comparable with Tannic acid standard (0.281±0.002) and is significantly more than aqueous extract.
Particle swarm optimisation with adaptive neighbourhood search for solving multi-objective optimisation problems

This paper proposes a new variant of PSO algorithm with adaptive neighbourhood search of Pareto solutions to solve multi-objective optimisation problems. This algorithm essentially consists of identifying the particles responsible for worst solution and accelerating these particles towards the best solution in an adaptive manner. This concept is hybridised with the updation strategy of non-dominated solution using crowding distance. Performance of the proposed algorithm is demonstrated by solving standard multi-objective benchmark problems including CEC 2009. In particular we compare our method with two recent algorithms by considering the inverted generational distance, spacing, convergence and diversity as the performance metrics. The proposed algorithm is also compared with recent state of art methods in terms of inverted generational distance. The results demonstrate that the proposed algorithm is quite competitive in terms of the mentioned performance indicators as compared to other algorithms.

The hydrologic impact of daily versus seasonal scaling of rainfall in climate change studies

There have been numerous recent studies examining the hydrologic consequences of climate change. One of the largest of these is the CSIRO Sustainable Yields project which is being carried out across four regions in Australia - the Murray-Darling Basin, South-west Western Australia, Northern Australia, and Tasmania (http://www.csiro.au/partnerships/SYP.html). The Sustainable Yields project has made an implicit assumption that the scaling of different daily rainfall amounts by a different factor has a significant impact on hydrologic response. This paper aims to test the hypothesis that this daily scaling of rainfall produces a measurable impact on hydrologic response. To test this hypothesis, two different time series of rainfall are created. The first scales all of the daily rainfall amounts in a season by the same factor, for example, all of the daily rainfall in summer (DJF) may be scaled down by 15%. The second also has a 15% reduction in summer rainfall, but the individual daily amounts are scaled differently depending on the volume of daily rainfall; for example, the first percentile of rainfall may be scaled up by 5%, with consequently greater reductions in the remainder of the rainfall such that the overall total reduction in summer rainfall is 15%. These two time series are derived for 15 of the 23 IPCC GCMs (General Circulation Models) which have readily accessible daily rainfall data. For each of the 15 GCMs, these two time series of rainfall are then used as inputs into the SIMHYD rainfall-runoff model and the hydrologic impact of the daily scaling examined. Results show that changes in the 1 st percentile of rainfall (i.e. the most intense daily rainfall events) average between -4 and +8% across Tasmania for 15 of the GCMs in the 4 th IPCC report, however these increases can be much greater over specific geographic areas. These average changes in 1
Women’s Economic Inactivity and Age. Analysis of the Situation in Poland and the EU

The group of economically inactive women is heavily diversified. The reasons for staying outside the labour market are the important factors that differentiate this group. They depend on the age or level of education among others. In addition, there is great geographical heterogeneity of the reasons for economic inactivity. Hence, two questions arise. Firstly, how significant is the geograph­ical diversity of the reasons for staying outside the labour market in the European Union? Secondly, have these geographical differences been changing over time? The main aim of the analysis is the classification of the EU countries taking into consideration reasons for women’s economic inactivity in different age groups. The analysis is carried out applying descriptive statistics and the k‑means method. The data are taken from the publicly available Eurostat’s Labour Force Survey datasets. The study of general tendencies in women’s economic inactivity covers the years 2000–2016. In turn, cluster analysis was carried out for data from 2006, 2010 and 2014. The obtained results confirmed significant diversity of the EU states. In addition, this geographical diversity has been changing over time. We receive the greatest similarity of classification obtained for different periods for the 50–64 age group and the smallest for the 25–49 age group. Moreover, there are noticeable tendencies of a significant decrease in the share of the economically inactive in the group of the oldest individuals (aged 50–64) in the sample. On the other hand, in the youngest group (individuals aged under 25), there are opposite tendencies observed – the share of those who remain outside the labour market increases.
Mechanism design and allocation algorithms for network markets with piece-wise linear costs and externalities

Motivated by market power in electricity market we introduce a mechanism design in [1] for simplified markets of two agents with linear production cost functions. In standard procurement auctions, the market power resulting from the quadratic transmission losses allow the producers to bid above their true value (i.e. production cost). The mechanism proposed in the previous paper reduces the producers margin to the society benefit. We extend those results to a more general market made of a finite number of agents with piecewise linear cost functions, which make the problem more difficult, but at the same time more realistic. We show that the methodology works for a large class of externalities. We also provide two algorithms to solve the principal allocation problem.
Real-Time Whole-Body Imitation by Humanoid Robots and Task-Oriented Teleoperation Using an Analytical Mapping Method and Quantitative Evaluation

Due to the limitations on the capabilities of current robots regarding task learning and performance, imitation is an efficient social learning approach that endows a robot with the ability to transmit and reproduce human postures, actions, behaviors, etc., as a human does. Stable whole-body imitation and task-oriented teleoperation via imitation are challenging issues. In this paper, a novel comprehensive and unrestricted real-time whole-body imitation system for humanoid robots is designed and developed. To map human motions to a robot, an analytical method called geometrical analysis based on link vectors and virtual joints (GA-LVVJ) is proposed. In addition, a real-time locomotion method is employed to realize a natural mode of operation. To achieve safe mode switching, a filter strategy is proposed. Then, two quantitative vector-set-based methods of similarity evaluation focusing on the whole body and local links, called the Whole-Body-Focused (WBF) method and the Local-Link-Focused (LLF) method, respectively, are proposed and compared. Two experiments conducted to verify the effectiveness of the proposed methods and system are reported. Specifically, the first experiment validates the good stability and similarity features of our system, and the second experiment verifies the effectiveness with which complicated tasks can be executed. At last, an imitation learning mechanism in which the joint angles of demonstrators are mapped by GA-LVVJ is presented and developed to extend the proposed system.
A modified P&O MPPT algorithm for single-phase PV systems based on deadbeat control

A modified perturb and observe (P&O) algorithm is presented to improve maximum power point tracking (MPPT) performance of photovoltaic (PV) systems. This modified algorithm is applied to a single-phase PV system based on deadbeat control in order to test the tracking accuracy and its impact on the reliability of the whole system. Both simulations and experimental results show that the proposed algorithm offers a fast response as well as smaller steady-state oscillations even under low irradiance condition compared with classical methods.
Banking Policy without Commitment: Suspension of Convertibility Taken Seriously

We study banking policy credibility in a variant of the Diamond and Dybvig (JPE, 1983) model. By committing to temporarily close banks during a run, suspending the convertibility of deposits into currency, the banking authority can eliminate the possibility of a bank run as an equilibrium outcome. Without commitment, however, if a run were to actually occur it may not be optimal for the authority to keep its promise to suspend convertibility. In other words, the threat of suspension may not be credible. We derive conditions under which a credible suspension scheme can be used to rule out bank runs and conditions under which it cannot. In the latter case, bank runs can occur even when there is no uncertainty about aggregate liquidity demand. We relate the analysis to events in Argentina in 2001, when a system-wide suspension of convertibility was declared but only partially enforced
Change in Fixed Costs and the Division of Labor within Firms through Labor Reallocation

This paper investigates the effects of a decrease in fixed costs on the division of labor within firms. In the constant markup rate model, a decrease in fixed costs curbs the division of labor. In the short run, the division of labor is promoted through labor reallocation within firms while in the long run, the division of labor is curbed through labor reallocation across firms. The latter effect dominates the former effect. In the variable markup rate model whose markup rate depends on the number of firms, the decrease in fixed costs induces labor reallocation across firms which is the opposite direction of that of the constant markup rate model in addition. The direction of labor reallocation across firms based on procompetition is opposite to that of the model of Kamei (2014) which does not impose free-entry and free-exit condition. The free-entry and free-exit condition plays a key role in determining the direction of that reallocation based on procompetition effect.
Developing an Educational Augmented Reality Game on the Battle of Mactan Using the Intel Perceptual Computing Kit

The purpose of this study is to produce an educational augmented reality game for elementary students taking up Philippine history in their Araling Panlipunan class. The product aims to address the lack of educational software on Philippine-specific topics by making use of the advantages offered by augmented reality. To achieve this goal, the research group developed an educational game on the Battle of Mactan using the Unity game engine in conjunction with the Intel Perceptual Computing Kit. Users play as a contestant in a game show called Zubu: Battle of Mactan, competing in a quiz show with AI opponents and playing mini games to learn about the historical battle. Information was organized into three segments: people, events, and culture. Augmented reality features such as gesture recognition and hand tracking were used to facilitate the controls of the game, alongside traditional keyboard and mouse input. The game showed promising short-term results through the demonstrated improvement between pre-game and post-game test scores of the students. The game may prove to be a helpful tool in learning but may still need further development in order to fully maximize its potential as an aid in teaching.
Vivianite and siderite in lateritic iron crust: an example of bioreduction

Lateritic iron crust (LIC) samples from Padauari (AM) were analysed by XRD, optical microscopy and SEM-EDS. The equilibrium of iron minerals (IM) was studied using Eh-pH diagram. It was shown that the minerals of the LIC are goethite (a-FeOOH), vivianite [Fe3(PO4)2.8H2O] and siderite (FeCO3). Carbonate grains are a solid solution of FeCO3-MnCO3. The LIC presents textures and structures of dissolution of IM. The siderite and vivianite are stable from Eh =-0.3 to 0.0 V and pH=5.0-7.5. These results indicate that vivianite and siderite are products of bioreduction through biogenic dissolution of IM, the new conditions of ecosystems of the Amazon region.
Yttrium aluminum monoclinic (YAM) synthesized by high energy ball milling

The structural of the mixture of Y2O3-Al2O3 has been studied using X-ray diffraction and 27Al MAS NMR. The sample was synthesized by high energy ball milling process. The polycrystalline YAM powder was form together with impurity YAP and Y2O3 when heated at 1100oC as confirm by XRD and NMR. Increasing heating temperature up to 1400oC did not seem enough to completely transform Y2O3 and α-Al2O3 into YAM phase as the grain growth occur and increase the diffusion distance in solid state reaction.
EXISTENCE OF INDECOMPOSABLE CONTINUA FOR UNSTABLE EXPONENTIALS

In the parameter plane for the complex exponential family Eλ(z) = λe z there exist parameters for which the orbit of zero lies on dynamical curves which are invariant under a fixed power of Eλ. At the same time, the orbit of zero tends to infinity and in these cases, the Julia set for Eλ is the whole complex plane. We construct fundamental regions based on these dynamical curves. Inside each region, we show the existence of an invariant set that, once properly compactified, becomes an indecomposable continuum.
