Amelioration of lead toxicity by 24-epibrassinolide in rose-scented geranium [Pelargonium graveolens (L.) Herit], a potential agent for phytoremediation

Effect of 24-epibrassinolide (EBL) on the growth of rose-scented geranium [Pelargonium graveolens (L.) Herit] subjected to lead toxicity stress was investigated. Supplementation of EBL substantially alleviated the inhibitory effect of lead on the plant growth. Further, it was observed that EBL feeding negated the deleterious impact of lead toxicity on chlorophyll levels. The studies clearly demonstrated the lead toxicity amelioration capability of epibrassinolide in case of geranium, an aromatic plant with potential for phytoremediation.
The Wireless Body Area Sensor Networks and Routing Strategies: Nomenclature and Review of Literature

WBASN is an effective solution that has been proposed in terms of improving the solutions and there are varied benefits that have been achieved from the usage of WBASN solutions in communication, healthcare domain. From the review of stats on rising number of wireless devices and solutions that are coming up which is embraced by the people as wearable devices, implants for medical diagnostic solutions, etc. reflect upon the growing demand for effective models. However, the challenge is about effective performance of such solutions with optimal efficiency. Due to certain intrinsic factors like numerous standards that are available, and also due to the necessity for identifying the best solutions that are based on application requirements. Some of the key issues that have to be considered in the process of WBASN are about the impacts that are taking place from the wireless medium, the lifetime of batteries in the WBASN devices and the other significant condition like the coexistence of the systems among varied other wireless networks that are constituted in the proximity. In this study, scores of models that has been proposed pertaining to MAC protocols for WBASN solutions has been reviewed to understand the efficacy of the existing systems, and a scope for process improvement has been explored for conducting in detail research and developing a solution.
Effects of water-soluble extractives on the moisture sorption properties of spruce wood hygrothermally treated at 120°C and different humidity levels

ABSTRACT Sitka spruce wood specimens were heated at 120°C and different relative humidity during heating (RHh) levels for 2–7 days and their equilibrium moisture contents (EMCs) were measured at 25°C and 11–97% relative humidity (RH) before and after the removal of the water-soluble extractives. By heating at 80% RHh or less, a longer heating at higher RHh resulted in a greater reduction in the EMC; further, the reduction in EMC was greater at higher RH. Conversely, the EMC value of the wood specimens heated at 100% RHh demonstrated a steep increase at high RH levels, exceeding that of the unheated wood at 97% RH. An increase of this nature in EMC was not realized after the removal of the water-soluble extractives. These results indicate that the deliquescent nature of water-soluble extractives, the decomposition residue of hemicelluloses, has significant influence on the moisture sorption of wood when the wood is heated in saturated water vapour.
Relative Liquidity, Fund Flows and Short‐Term Demand: Evidence from Exchange‐Traded Funds

We show that highly liquid Exchangeâ€ Traded Funds (ETFs), especially those that are more liquid than their underlying basket of securities (i.e., positive relative liquidity), are particularly attractive to investors. Using three definitions of liquidity, we find that relative liquidity predicts net fund flows, as well as inflows and outflows positively and significantly. We further document a liquidity clientele among institutional investors: (i) relative liquidity is significantly more important for shortâ€ than for longâ€ term investors; and (ii) relative liquidity is inversely related to investorsâ€™ average holding duration in the ETFs. These two findings provide evidence that relative liquidity encourages shortâ€ term demand.
A new model of Car Parking System trough Genetic Algorithms

This research introduces the development of an automatic control system for the determination of a set of necessary maneuvers for reverse parking of a car. From the study of solutions proposed in literature, we have used the mathematical model of the problem and have proposed the determination of parking trajectory through genetic algorithms. This paper presents the mathematical model, the characteristics of the genetic algorithms and the relative software that has been used. Moreover we also describe and explain by help of experiments the validity of our solution.
Power, identity, modernity. Individualisation and destabilisation in a globalised world

In what is called, with an almost worn-out word, a globalised world, individualisation and destabilisation seem to be the two most central traits in both politics and society, internationally as well as within nation states. Destabilisation and individualisation are rooted in the communicational revolution and the way in which this has changed the prerequisites for the exercise of power and identity formation in today’s world. The globalisation effects on different types of political power distributions are still under scrutiny (Aday and Livingstone 2008). Some researchers argue for a strengthening of democracy, while others have a much more negative view on the effects of globalisation (Held et al. 1999, Bentivegna 2006). Some state that since the depth of the communication revolution and the media situation tend to vary significantly in different contexts, it is impossible to generalise their relationship to democracy. Whether or not globalisation leads to structural and policy convergence is still at the centre of debate (Graber 2003, Brundin 2008). Theoretically, individualisation manifests itself on the international level as an ever-stronger position of human rights, at the expense of state sovereignty (Risse et al. 1999). Nationally, individualisation means, for example, an increased importance of the specific competencies of the individual in the labour market and a decreasing interest in collective political activities (Bjereld and Demker 2006, 2008). Internationally, destabilisation manifests itself as a loosening up of the sovereignty of the nation state, increased importance of different types of transnational networks and a weakened position of the state sovereignty-based international law (Berlin 2007, Brundin 2008). Nationally, destabilisation means a loosening-up of the class structures of the industrial society and of the traditional professional roles and cleavages that came with the national and industrial revolutions (Bjereld and Demker 2006, 2008). In an ever-abundant discourse on globalisation it is only rarely that one finds questioning of why and in what way the communicational revolution has contributed to an increased destabilisation and individualisation of politics and society. Also, there is still a lack of empirical research into the development of destabilisation and individualisation over time. In this special issue the articles try to formulate and test hypotheses about individualisation and destabilisation in politics and society. Our aim is to increase our understanding of the communicational revolution’s
Appraisals of Intervention: The Mother's versus the Culprit's Behavior as Determinants of Children's Evaluations of Discipline Techniques.

SIEGAL, MICHAEL, and COWEN, JAN. Appraisals of Intervention: The Mother's versus the Culprit's Behavior as Determinants of Children's Evaluations of Discipline Techniques. CHILD DEVELOPMENT, 1984, 55, 1760-1766. 20 children in each of 5 groups (mean ages = 5-9, 8-9, 11-9, 14-7, and 17-8) were asked to evaluate the disciplinary techniques employed by mothers over a range of situations in which a culprit was described as having transgressed. Maternal child-rearing strategies consisted of induction, physical punishment, love withdrawal, and permissiveness. Across all ages, evaluations were determined by the technique employed by the mother in interaction predominantly with the type of situation, and secondarily with the nature of the child making the evaluation. As predicted, children tended to prefer the "authoritative" parent by expressing strong approval for induction accompanied by mild approval for physical punishment. Contrary to expectations, both preschoolers and schoolchildren generally rated induction as favorably as physical punishment. While favorable ratings of physical punishment generally declined with age, there were no age differences in evaluations of induction in some situations. The implications of children's evaluations of discipline techniques for parent-child interaction are discussed.
A task-based sparse direct solver suited for large scale hierarchical/heterogeneous architectures

In this talk we will discuss our research activities on the design of parallel linear solvers for large scale problems that range from dense linear algebra, to parallel sparse direct solver and hybrid iterative-direct approaches. In particular we will describe the implementations designed on top of runtime systems that should provide both code and performance portabilities. Finally, we will present some preliminary results on the integration of h-matrice kernels in our sparse direct solver framework.
Symmetry-related growth of carbon nanocoils from Ni–P based alloy particles

Nanocrystalline Ni–P and Ni–X–P (X=W,Co,Cu) alloys deposited on the surfaces of SiC whiskers were evaluated on their roles in the catalysis growth of carbon nanocoils during thermal pyrolysis of acetylene. Experimental results indicated that the Ni–P and Ni–W–P systems were effective in catalyzing the growth of carbon nanocoils with varying chirality. Single-particle related growth of the single- or multihelixed carbon nanocoils was found, which suggests that these nanocoils have specific growth characteristics closely related to the symmetroid or surface symmetry of the catalyst particle.
The Mediating Effects of Learnability and Interaction on the Perceived Usability of Smartphone Applications

Even though the smartphone applications bring versatility into our lives, they are still considered to be less usable than the PC. This is mainly due to limitations in the hardware, especially the small display of the smartphones compared to the PC. Furthermore, applications are growing along with the addition of more functions and information. Generally, complicated applications are more difficult to learn how to use and to interact with. Thus, these conditions and circumstances bring challenges for the applications in terms of the usable user interface (UI). A comprehensive IS literature review found that there are few empirical researches on the effect of UI design on the perceived usability of applications in the context of smartphone. Thus, the main research goals of this study are as follows: 1) to examine the effects of UI design on the learnability of smartphone applications and the interaction between users and applications, and 2) to find the effects of the learnability and the interaction on the usability of the applications as perceived by users. A survey was conducted to collect data and Structural Equation Modeling (SEM) was employed to analyze the data. The results showed the significant direct effects of UI design on the learnability of applications and the interaction between users and applications. In addition, the results of this study also showed the significant effect of the learnability of applications, as well as the significant impact of the interaction on the usability of the applications as perceived by users. However, there was no significant direct effect of UI design on the perceived usability of applications.
Geometric path following control of a rigid body based on the stabilization of sets

Abstract The paper describes an approach to the development of the geometric path following control for a rigid body. Desired path of movement in the space is represented by an intersection of two implicit surfaces. Path following control problem is posed as a problem of maintaining the holonomic relationships between the system outputs. Control is synthesized using the differential geometrical method through nonlinear transformation of initial dynamic model. The main results presented are the model of spatial motion and relevant nonlinear control algorithms.

From Schutz to Dewey: communication and everyday life

This paper presents and discusses the correlations between John Dewey’s pragmatist philosophy and Alfred Schutz’s phenomenological philosophy – both as contributions to building up a communicational paradigm useful as an epistemological grounding and a methodological framework for Communication Sciences. We discuss the possible knowledge present in the relationship between communication and philosophy starting from the seminal notions of communication for Schutz and Dewey. These authors’ ideas relate to each other in the lifeworld or the natural environment, in the everyday life and in action. The conclusion of this paper demonstrates the application of philosophical notions to communication studies, to the perception of technology and to techniques related to technology, moving beyond a reductive and incomplete instrumental perception. Technology and techinique are all the intelligent means by both man’s and natural environment’s energy are directed and used to fulfill the human needs; and these are not limited to a few exterior forms nor comparatively mechanical.
Potentialities and limitations of network analysis methodologies: a theoretical model focused on the Social Sciences

This paper explores the potentialities and limitations of network analysis, not only as a methodological tool that may be used in Social Science research but also as a separate discipline, with its own well-tested theories. Providing a framework for the use of network analysis involves discussing the role that it can play in understanding objects using a field that is sometimes accused of being too technical. Despite the fact that it has increased in popularity over recent years, driven by new communication technologies and especially social media channels, network analysis has a much broader use, and we therefore aim to demonstrate some innovative approaches that may be used in Social Science research. Finally, because it is an interdisciplinary methodology, we discuss some of the associated risks and biases.
Assigning Polarity Scores to Facebook Myanmar Movie Comments

User-generated texts such as reviews, discussions or comments are valuable indicators of users’ preferences. Apart from binary classification (positive or negative) of the reviews, some researchers calculated polarity scores that give a very concise summary and provide more information of the reviews. In this paper, a system for assigning polarity scores to Facebook Myanmar movie comments is proposed. Myanmar is a language with underdeveloped electric resources. As this is pioneering work for this combination of language and sentiment analysis, the polarity scores of each positive and negative word in the movie domain-specific polarity lexicon is calculated. And then the polarity scores to each comment of the plain text movie corpus are assigned. The proposed system achieves 89% and 85% accuracy on positive and negative opinion words respectively in the evaluation of polarity score lexicon. We also make the comment polarity for 3-class evaluation and 5-class evaluation based on the scores of comments.
PARALLEL MULTIAGENT METHOD OF BIG DATA REDUCTION FOR PATTERN RECOGNITION

Context. The problem of feature selection for big data processing based on the multi-agent approach and parallel computation has been solved. The object of research is the process of feature selection. The subject of the research are the methods of feature selection. Objective. The purpose of the work is to create a parallel multi-agent method for reducing of big data sets. Method. The article deals with the parallel multi-agent method for reducing of big data sets. The developed method involves splitting multiple agents into several subsets for parallel search of an informative combination of features in different areas of the search space. At the same time, it is suggested that the parallel nodes of the computer system perform the most resource-intensive operations associated with estimating the current set of agents, as well as the need to create and modify new sets of solutions based on stochastic computations. This allows to speed up the process of multi-agent search of informative combination of features, as well as to reduce the practical threshold for application of the multi-agent method with indirect communication between agents for reducing big data sets. Results. The software which implements the proposed method and allows to select informative features based on the multi-agent approach and parallel computation has been developed. Conclusions. The conducted experiments have confirmed the proposed software operability and allow recommending it for use in practice for solving the problems of big data processing for pattern recognition. The prospects for further research may include the modification of the developed parallel method for feature selection by using different criteria for estimation of the group information of features, as well as an experimental study of proposed method on more complex practical problems of different nature and dimensionality.
The effect of time on market and location in the housing market: A case study in taoyuan metropolitan area

This paper utilizes the survival model to investigate the relationship between selling time of a building and its determinants. The results indicate that the bigger the land size, the shorter the duration of marketing time for both dwellings and commercial buildings. The proximity of business premises to universities, train station and police office have longer selling time. We find that, on the other hand, the residents seem to be more concerned with accessibility to a police office for public security and a shopping center or park for improved life quality. In addition, newer houses could be sold faster than the old ones that have narrow fire lane and poor inner decoration. Furthermore, the unit price of land representing the quality of house leads to a longer selling time for the rich.
Adaptive Backstepping Control of an Indoor Micro-Quadrotor

Micro-Quadrotor is one of the most popular VTOL (Vertical Take-Off and Landing) aerial robots and has enormous potential applications in the field of near-area surveillance and exploration in military and commercial applications. However, stabilizing and position control of the robot are difficult tasks because of the nonlinear dynamic behavior and model uncertainties. Backstepping is a widely used control law for under- actuated systems including quadrotor. But general backstepping control algorithm needs accurate model parameters and isn't robust to external disturbances. In this study, an adaptive integral backstepping control algorithm is proposed to realize robust control of quadrotor. The proposed control algorithm can estimate disturbances online and therefore improve the robustness of the system. Both simulation and experiment results are presented to validate the performance of the proposed control algorithm.
The effect of collaborative learning on the problem-solving skills of children with Down syndrome

Down syndrome (DS) is one of the biggest causes of learning disabilities (LD: 'mental retardation' in the U.S.), with the majority of affected persons having moderate to severe learning disabilities. Specific learning problems such as a failure to consolidate new learning and a counterproductive approach to learning have also been identified. Collaborative learning has been shown to be effective in facilitating learning in typically-developing (TD) children but little research has addressed its potential in children with LD. Those studies which do exist tend to be outcomerather than processoriented. This thesis examined the effect of collaborative learning on children with DS through three inter-linked studies. The first study investigated unstructured collaborations on a Lego construction task in children with DS who were paired with developmentally agematched children with non-specific learning disabilities (NSLD) and in pairs of similarly-matched TD children. Preto post-test score comparisons demonstrated significant improvements for the groups of participants overall, but no group differences were found. Qualitative analyses of interactions found no group differences in the proportion of time spent off-task, amount of eye contact or amount of off-task speech. Proportionally, the participants with DS used as much speech indicative of cognitive conflict as the TD participants and showed the least negative speech. They also, however, produced significantly less goal-directed speech than did the TD participants. The second study sought to determine whether collaboration with a peer could facilitate conceptual understanding in children with DS. Groups of non-conserving children with DS and children with NSLD were paired with conserving children with NSLD on conservation of number and conservation of matter tasks. Following collaboration more than half the participants with DS showed improvements in understanding of conservation of number. The results seem to support the Piagetian notion that sociocognitive conflict after exposure to a differing viewpoint can lead to cognitive advancement. However, as exposure to a more advanced model also constitutes a tutoring model, the results can equally be interpreted from a more Vygotskian perspective. The third study assessed the extent to which children with DS were able to benefit from contingent teaching, or 'scaffolding' by comparing the effects on performance on a spatial matching task of two adult-led interventions (direct teaching or contingent teaching) with a control condition. Participants in the contingent condition showed significant preto post-test gains as well as improvements on a similar task for which no intervention had been implemented. Participants in the two other conditions showed no significant gains, suggesting that for children with DS, contingent teaching is more effective than strategies in which a solution is explicitly taught.
