Silver Oxyfluoride Modified Silver Electrode: Application for Electrocatalytic Oxidation of Methanol

Silver oxyfluoride modified silver electrode was prepared and used to electrocatalytic oxidation of methanol. Fluoride can form a complex with silver ion, and thus be used to modify a silver electrode surface. The electrocatalytic activity of the modified electrode for the oxidation of methanol, in aqueous basic solution was studied by using cyclic voltammetry. Results showed that, silver oxyfluoride modified electrode can improve the activity of Ag towards the oxidation of this small organic molecule. The exchange current density (j0) were 20.37, 10.38 and 1.61 folds higher than for that of bare silver electrode respectively for silver oxyfluoride, silver oxychloride and silver oxybromide modified silver electrodes.The modified electrode showed a stable and linear response in the concentration range of 5×10 -3 to 5×10 -2 mol L -1 with a correlation coefficient of 0.9953. For silver oxyfluoride modified silver electrode, the transfer coefficient (α), the number of electrons involved in the rate-determining step (nα) and the catalytic rate constant (k) for modified electrode were calculated as 0.45,1 and1.113×10 5 cm 3 mol -1 s -1 respectively.
Promotions in the Spanish Labour Market: Differences by Gender

In this paper we compare the professional careers of women and men in the Spanish labour market. We use a sample from the Encuesta de Estructura, Conciencia y Biografia de Clase (1991) to estimate count data models (negative binomial models) to explain the number of promotions received in the firm, for males and females separately. Then, using the estimated coefficients from these models, we apply a variant of Oaxaca's decomposition approach to divide the gap in average promotions by gender into two parts: one of them due to differences in endowments and the other is associated with differences in the "return" of such as endowments in terms of opportunities of upward mobility. The findings indicate that women receive fewer promotions than men with the same qualifications due to differential treatment in the market. Copyright 2001 by Blackwell Publishing Ltd
MATERIAL MODELLING OF EVOLVING ELASTIC AND PLASTIC ANISOTROPYWITH APPLICATION TO DEEP DRAWING PROCESSES

The paper proposes a hyperelasticity-based concept of finite strain plasticity with combined hardening using evolving structure tensors to represent the evolution of elastic and plastic anisotropy in the material. By defining the Helmholtz free energy density and the yield surface as functions of the evolving structure tensors, we are able to describe both evolving elastic and plastic anisotropy, respectively. The model considers also nonlinear kinematic and isotropic hardening and is derived from a thermodynamic framework based on the multiplicative split of the deformation gradient. The kinematic hardening component represents a continuum extension of the classical rheological model of Armstrong-Frederick kinematic hardening. Exploiting the dissipation inequality leads to the important result that the model includes only symmetric tensor-valued internal variables. Evolution of elastic and plastic anisotropy is numerically investigated by means of simulations of cylindrical deep drawing of metal sheets and thermoforming of thermoplastic polymer blends.
Identification and Molecular Characterization of Methionine Sulfoxide Reductase B Gene in Rice Blast Fungus, Magnaporthe oryzae

Magnaporthe oryzae, a major cause of rice blast, is one of the most destructive plant fungal pathogens. Secretion of reactive oxygen species (ROS) during the infection phase of plant pathogenic fungus plays a key role in the defense mechanism of a plant. ROS causes oxidative damage and functional modification to the proteins in a pathogenic fungus. Methionine, especially, is a major target of ROS, which oxidizes it to methionine sulfoxide. To survive from the attack of ROS, plant pathogenic fungus has antioxidative systems - one example would be methionine sulfoxide reductase B (MSRB), which reverses the oxidative alteration of methionine to methionine sulfoxide. In the present study, identification and molecular characterization of the MSRB gene in M. oryzae KJ201 were investigated. The MSRB gene was amplified by PCR from the M. oryzae KJ201 genomic DNA. The copy number of MSRB in the genome of M. oryzae KJ201 was identified by Southern blot analysis, which revealed that the gene exists as a single copy. To study the molecular function of an MSRB gene, the expression level of the MSRB gene was assayed with hydrogen peroxide treatment by Northern blot analysis and RT-PCR. The expression of the MSRB gene was increased by treatment of hydrogen peroxide, without significant correlation to hydrogen peroxide concentrations. These results indicate that the MSRB gene in M. oryzae KJ201 could contribute to protection against plant defense compounds such as ROS and offer a novel strategy for the control of rice blast.
FLUTE, A COMPACT ACCELERATOR-BASED SOURCE FOR COHERENT THZ RADIATION

In this paper beam dynamics simulations of the Linacbased THz source FLUTE (Ferninfrarot Linac- Und TestExperiment) are presented. The optimization of various machine parameters such as laser spot size, laser pulse length, and lengths of the chicane magnets are discussed. Spectra of the generated coherent THz radiation, which depend on the compressed bunch length and charge, are shown.
ENTRIES, EXITS AND THE RESOURCEALLOCATION: AN ANALYSIS OF THE BANKING INTERMEDIATION IN BRAZIL

This work employs established concepts of Industrial Organization and Labor Economics in order to propose two new measures to characterize the Brazilian banking sector. The first one is called Banking Turbulence Rate. It shows the presence of a massive majority of municipalities with very low levels of banking intermediation. The second indicator is the Net Absorption of Resources Rate and it points to the dominance of deposit-raising operations in the Brazilian banking sector. Econometric models point to the local level of income and the degree of banking competition as main determinants of these banking indicators.
IMPLEMENTATION OF DIGITAL STATIC VAR COMPENSATOR (SVC) WITH THYRISTOR BINARY COMPENSATOR AT 2 KVA TRANSFORMER

Electrical distribution systems are incurring large losses as the loads are wide spread, inadequate reactive power compensation facilities and their improper control. In solution the experimental studies of static VAr compensator (SVC) with thyristor binary compensator is carried out. The work deals with the performance evaluation through analytical studies and implementation of hardware circuit model of SVC at single phase, 50Hz, 2kVA transformer. The SVC consisting of thyristor switched capacitor bank in binary sequential steps. This compensation technique facilitates control on the reactive power depending on load requirement so as maintain power factor near unity always, which results in efficient electrical power system.
Transformational Leadership: Implications for Organizational Competitive Advantage

There is a growing consensus among scholars and practitioners alike that maximising the potentials of human resources is central to organisational effectiveness and improved performance in the 21st century global market place of intense competition. It has also been suggested that the ways in which organisational leaders manage people can remarkably influence company performances and competitiveness. Despite this realisation however, scholars, managers and practitioners alike disagree on the most appropriate approach to organisational leadership. Indeed, there is an on-going debate about the leadership style that yields the best results for organisations in contemporary times. And whilst the debates rage, an increasingly dominant discourse is that transformational leadership is central to organisational effectiveness and gaining of competitive advantage. This notwithstanding, the most fundamental issue remains how to understand how transformational leadership practices impact on performance in practical terms. Consequently, producing an unequivocal response to the question ‘what does transformational leadership really contribute to organisational performance? ’ has remained elusive. It is against this backdrop, that this article critically evaluates the concept of Transformational Leadership (henceforth TL), with a view of highlighting its contributions to organisational effectiveness and performance. Synthesising organisational and leadership theories and integrating literatures in organisational development and HR, the paper argues that there are evidences to suggest that there are clear linkages between TL, organisational effectiveness and improved performance. The paper further contends that emotional intelligence is key to the operationalization of TL and concludes that the greatest challenge remains how to quantify the contributions of TL in practical terms.
Auxin effectively induces the formation of the secondary abscission zone in Bryophyllum calycinum Salisb. (Crassulaceae)

We have found that auxin, indole-3-acetic acid (IAA) substantially induces the formation of the secondary abscission zone in stem and petiole explants and in decapitated stem and petiole after excision of blade in intact plants of Bryophyllum calycinum when IAA at a concentration of 0.1% as lanolin paste was applied in the middle of these organs. The secondary abscission zone was formed at a few mm above of the treatment with IAA, and senescence of the part above abscission zone was observed. IAA additionally applied on the top of explants or top of the dacapitated stem or the debladed petiole totally prevented the secondary abscission zone formation and senescence induced by IAA applied in the middle of these organs. Possible mechanisms of the formation of the secondary abscission zone are discussed in terms of the interaction of auxin and ethylene.
A Platform for the Geometry Friends Cooperative Game AI Competition

This paper describes the development of a new online competition platform to support the future of the Geometry Friends Cooperative Game AI competition. Geometry Friends is a cooperative 2D physics-based platformer that presents several challenges for the AI community, in particular, to integrate motion and task planning. This paper presents the work developed to improve the platform used to run the competition. The work was based on best practices of similar platforms. The new platform was developed mostly from scratch, consisting of a new website and a background program in charge of fully handling the received submissions, and more. Virtualization was used to create a secure, fair and reusable evaluation environment. Different features of the new platform were tested by several people across three different test scenarios. The new website was concluded to have an above average usability, while the submission handling program worked as expected throughout the testing phase.
The thermodynamic properties of tetraethoxysilane (TEOS) and an infrared study of its thermal decomposition

A review is given on the determination of the thermodynamic properties of Si(OC 2 H 5 ) 4 (TEOS, tetraethoxysilane). In addition, the thermal decomposition of TEOS has been studied by in-situ IR spectroscopy. The decomposition products in the gas phase in the absence of oxygen are organic fragments (ethanol, ethanal, ethene, methane, carbon monoxide), and in the presence of oxygen water, carbon dioxide, ethanal and methanal. The results are compared with thermodynamic equilibrium calculations and kinetic models
Empirical Study of Effects of Local Financial Structure on Regional Economic Growth ( Studies Conducted in Regencies in the Province of East Java , Indonesia )

Fiscal decentralization is a policy which is implemented in countries to improve the welfare of societies. Indonesia has officially implemented fiscal decentralization policy since January 1, 2001. The implementation of the decentralization gives more authorities to local government to run government-related affairs ranging from planning, management, and evaluation. Therefore, local government will be encouraged to empower all available potential resources to develop its regency. This triggers fundamental change in the regulation that controls the relationship between central and local government, especially in governmental administration and the financial balance between the central and local government. The implementation of fiscal decentralization marks the beginning of transformation which is embodied in Regional Government Budget. The increasing number of authorities in central government delegated to the local government causes the increase in own-source revenue (OSR) as a source of funding in regional financial structure. Potential sources of regional revenue should be maximally used without ignoring the rules embodied Abstract
Zagreb Polynomials of Three Graph Operators

In general, the relations among Zagreb polynomials on three graph operators are discussed in this paper. Specifically, relations between Zagreb polynomials of a graph $G$ and a graph obtained by applying the operators $S(G)$ , $R(G)$ and $Q(G)$ are investigated. In a separate section, the relation between Zagreb polynomial of a graph $G$ and its corona is also described.
Online Minimum-Jerk Trajectory Generation

Robotic trajectory generation is reformulated as a controller design problem. For minimum-jerk trajectories, an optimal controller using the Hamilton-Jacobi-Bellman equation is derived. The controller instantaneously updates the trajectory in a closed-loop system as a result of the changes in the reference signal. The resulting trajectories coincide with piece-wise fifth-order polynomial trajectories for piece-wise constant target states. Since having hard constraints on the final time poses certain robustness issues, a smooth transition between the finite-horizon and an infinite-horizon problem is developed. This enables to switch softly to a tracking mode when a moving target is reached.
Impact of Dental Caries on Quality of Life of School Children

Objective: To estimate the impact of dental caries on the oral health-related quality of life of school children of public schools of Tubarao, Santa Catarina, Brazil. Material and Methods: A cross-sectional study on a sample of 42310-15 years old students was carried out. The prevalence of dental caries, dental trauma and malocclusion was observed by oral examination based on WHO criteria. The Oral Impact on Daily Performance indicator was used to collect data about the impact on quality of life related to children’s oral health. The Chi-square test was used for bivariate analysis with significance levels set at p<0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated using log-linear Poisson regression with a robust estimator. Results: The prevalence of dental caries was 55.5%. The prevalence of impact on oral health related quality of life was 45.6%. OIDP dimensions significantly associated with dental caries were eating [PR = 1.45 (95%CI 1.06; 2.00)] (p = 0.021), sleeping [(PR = 2.29 (95%CI 1.15; 4.56)] (p = 0.018) and performing daily activities [PR = 2.57 (95%CI 1.06; 6.22)] (p = 0.036) after adjusting for gender, age and presence of dental trauma and malocclusion. Conclusion: Dental caries was found to be significantly associated with oral health-related quality of life of children in activities such as eating, sleeping, and performing daily activities.
Impact of Self Efficacy on Motivation and Performance of Employees

The aim of this study is to perform a meta-analysis which analyses the individual research findings which pertain to the relationship between self-efficacy, employee motivation and work related performance of the employee. From the results of the study it is observed that self-efficacy theory can be applied for work related performance in terms of motivating different employee related facets as well as organizational pursuits. In this study the researcher has attempted to assess the influence of self-efficacy on the performance of individuals at workplace and the mechanism by which self-efficacy of an individual determines his/her work related performance and motivation. Thus, it becomes necessary to identify the practical implications of the outcomes related to improving employee self-efficacy in order to motivate them and improve their performance.

A METHOD FOR ESTIMATING LONG-TERM CHANGES IN TIME-OF-DAY TRAVEL DEMAND

One of the desired features of a travel demand model is an ability to estimate not only 24-hr traffic volumes but also their distributions during the day. In this paper, usefulness of the recently proposed person-category trip generation model to address this issue is examined. A method to estimate time-of-day productions and attractions is proposed. The time-of-day travel profiles of homogeneous groups of persons from Lodz, Poland, and Baltimore, Maryland, are examined. Category-specific, time-of-day travel patterns appear consistent for different subareas within a given metropolitan area, whereas the differences in travel profiles among person-categories are high. This modeling approach provides insight into long-term changes in time-of-day travel distribution as a result of such trends as increase in female employment, increase in average age of the population, increase in automobile availability level, and so on. Forecast and policy implications are also discussed.
Facile synthesis and characterization of N-doped TiO 2 photocatalyst and its visible-light activity for photo-oxidation of ethylene

A facile wet chemical method was adopted for preparing highly photoactive nitrogen doped TiO2 (N-TiO2) powders with visible responsive capability, which could be achieved by the hydrolysis of titanium isopropoxide (TTIP) in the ammonium hydroxide precursor solution in various concentrations and then calcined at different temperatures. The N-TiO2 powders were characterized, and the photocatalytic activity was evaluated for the photocatalytic oxidation of ethylene gas under visible light irradiation to optimize the synthesizing conditions of N-TiO2 catalyst. The N-TiO2 photocatalytic powders were calcined in a range of temperatures from 300 to 600°C and obviously found to have greater photocatalytic activities than commercial TiO2 P25. The strong absorption in the visible light region could be ascribed to good crystallization and adapted sinter temperature of as prepared sample. XPS test demonstrated that the N was doped into TiO2 lattice and made an interstitial formation (Ti-O-N), and N doping also retarded the phase transformation from anatase to rutile as well. The N-TiO2 catalyst prepared with 150 mL ammonium hydroxide added and calcined at 500°C showed the best photocatalytic activity. The experimental results also proved the enhanced photoactivity of N-TiO2 material depends on the synthesizing conditions.
A formative study of disposal and re-use of old mosquito nets by communities in Malindi, Kenya

Background About 30 million insecticide treated mosquito nets have been distributed in Kenya since 2001 and ownership is approaching full coverage. As a consequence of this achievement, Kenya is faced with the challenge of disposing old mosquito nets that are no longer in use. The study aimed at investigating ways of disposal and re-use of old and torn nets by end users. Materials and Methods A formative study was conducted in the former Malindi District, which is comprised of Malindi and Magarini sub-counties of Kilifi County in Coastal Kenya. A total of 6 Focus Group Discussions, 10 Key Informant Interviews and 9 transect walks/drives were undertaken. Data from the different sources were analysed separately and triangulated for similarities and differences. Results There were variations in disposal and re-use of old nets between urban and rural or peri-urban residents. In all settings, people adopted innovative and beneficial ways of re-using old, expired nets, and those that were damaged beyond repair. Common causes of damage were fire, children, domestic animals sharing the sleeping room and friction from the bed poles while hanging or tacking it in under a sleeping mat. Re-use was most prominent in farming activities (78%) and less to for use in mosquito control, like window screening (15%). The remaining 8% was related to making ropes, swings, footballs, goal posts and fishing nets. Advantageous texture and nature of the netting material, perceived economic benefit and lack of guidelines for disposal were the main reasons cited by residents for re-using old nets. Conclusions It is important that re-use and disposal of old mosquito nets is distinguished from misuse of newly distributed mosquito nets. Alternative uses of old nets as opposed to misuse of new nets was found to be common in our study.
Identification and Expression Analysis of Fragaria Vesca MLO Genes Involved in Interaction With Powdery Mildew (podosphaera Aphanis)

Strawberry powdery mildew, caused by Podosphaera aphanis is a major fungal disease that affects strawberry yield and quality. In the model plant species Arabidopsis and the crop plants barley, tomato and pea, the Mildew resistance locus O (MLO) proteins have been found to be required for powdery mildew susceptibility. The present study, based on the sequence of a wild plum (Prunus americana) MLO protein, identified 16 MLO genes within the genome of woodland strawberry, Fragaria vesca and examined their expression pattern in response to powdery mildew infection in three diploid strawberry cultivars. Phylogenetic analysis showed that the FvMLO genes can be classified into six clades. Four FvMLO genes were grouped into clade III, which comprises MLO genes from Arabidopsis, tomato and grapevine that mediate powdery mildew susceptibility. A RNA-seq analysis of two diploid strawberry cultivars, F. vesca ssp. vesca accession Hawaii 4 (HW) and F. vesca f. semperflorens line “Yellow Wonder 5AF7” (YW) at 1 d (1 DAI) and 8 d (8 DAI) after infection showed the expression of 12 out of the 16 FvMLO genes. The comparison of Fragments Per Kilobase of transcript per Million mapped reads (FPKM values) detected by RNA-seq and expression values of qRT-PCR for FvMLO genes showed substantial agreement. The FvMLO3 gene, which was grouped in clade III and orthologous to the Arabidopsis, tomato and grapevine genes, was highly expressed in YW compared to other FvMLO genes across varieties. The results showed that FvMLO genes can be used as potential candidates to engineer powdery mildew resistance in strawberry based on MLO suppression or genome editing.
Optimized Detection of the Infrequent Response in P300-Based Brain-Computer Interfaces

This paper presents an application developed on the BCI2000 platform which reduces the average spelling time per symbol on the Donchin speller. The motivation was to reduce the compromise between spelling rate and spelling accuracy due to the large amount of responses required in order to perform coherent average techniques. The methodology was made under a Bayesian approach which allows calculation of each target’s class posterior probability. This result indicates the probability of each response of belonging to the infrequent class. When there is enough evidence to make a decision the system stops the stimulation process and moves on with the next symbol, otherwise it continues stimulating the user until it finds the selected letter. The average spelling rate, after using the proposed methodology with 14 healthy users and a maximum number of 5 stimulation sequences, was of 6.1 ± 0.63 char/min, compared to a constant rate of 3.93 char/min with the standard system.
