Article history: Received July 28, 2013 Accepted 14 January 2014 Available online February 28 2014 The new era introduced as a technology era, is important as promising of a new world with modern methods in better and more useful teaching, which result in progress in qualitative teaching of students in education. The aim of the present study is to learn more about the effect of electronic courses in mathematics on students’ social growth, cognitive growth and the quality of learning. Statistical population includes 55 teachers of junior high school in city of Khash located in south part of Iran, selected randomly based on Morgan Tables. To gather data, social growth, cognitive growth and learning quality questionnaires were used. To analyze data one-way analysis of covariance (ANOCOVA) test was used. The results reveal that electronic educational courses were effective on social growth and cognitive growth but not on learning quality. © 2014 Growing Science Ltd. All rights reserved.
Effect of exhaustive exercise on the immune system, measured through complement activation and C-reactive protein

Summary The infl uence of exercise in the systemic infl ammatory response has been a subject of debate for over ten years. However very few original studies have analyzed their activation and are practically nonexistent translational studies that have extrapolated the analysis results to the reality of athletes. Purpose: We aimed to determine the eff ect of exhaustive exercise on two known infl ammatory markers, the complement system and C-reactive protein, as a result of exhaustive exercise consisting of three intermittent bouts of 800 m at max speed interspersed with 30-s recovery intervals. Methods: Ten healthy volunteers were recruited. Anthropometric and V0 2max data were obtained in the laboratory and venous parameters of basal and immediate post-exercise CK, pH, lactate, complement and C-reactive protein were obtained on an open-air running track three days later. Results: Signifi cant increases in plasma CK (114.7±80.3, p=0.005) and lactate (17.27±5.5, p=0.005) were noted. Both parameters, increased CK and lactate post-exercise, correlated signifi cantly (r=0.751, r2=0.574, p=0.012). The complement system was activated, with the increase in CK predicting the increase in C3 (p=0.003). No post-exercise increase in C-reactive protein was found. Conclusion: The systemic infl ammatory response measured in terms of increases of the complement C3 and 4 was activated by exhaustive exercise. New studies are required to determine the physiological benefi t of this activation, and discriminate it from the prejudicial eff ects this activation could cause in other settings.
ANTIDIABETIC ACTIVITY OF PILOCARPUS MICROPHYLLUS EXTRACT ON STREPTOZOTOCIN-INDUCED DIABETIC MICE Research Article

The present study was designed to investigate the hypoglycemic and hypolipidemic properties of a methanolic extract of Pilocarpus microphyllus (P. microphyllus) which is widely used as a traditional treatment for diabetes mellitus. The methanolic extract of leaves of P. microphyllus administered orally at a dose of 100 mg/kg, for 15 days to streptozotocin-induced diabetic mice. Hypoglycemic effects, oral glucose tolerance test, change in body weight and lipid profile assessed in methanolic extract treated diabetic mice, were compared with normal animal, diabetic control and standard drug treated mice. Histological observation during 15 days treatment was also done. Methanolic extract of leaves of P. microphyllus produced a significant reduction in fasting blood glucose level in streptozotocin-induced diabetic mice. Significant differences were also observed in urine glucose level, oral glucose tolerance test, serum lipid profile and change in body weight by methanolic extract treated diabetic mice, when compared with diabetic control, normal control and standard drug treated mice. Histopathological studies of the pancreas of these animals showed comparable regeneration by extract which were earlier necrosed by streptozotocin. Methanolic extract of P. microphyllus exhibit significant anti-hyperglycemic and hypolipidemic activities in streptozotocin-induced mice. They also showed improvement in body weight, OGGT, urine glucose as well as regeneration of pancreatic islets of langerhans so might be value in treatment of diabetes.
Hacia una educación inclusiva y personalizada mediante el uso de los sistemas de diálogo multimodal

Continuous advances in the development of information technologies have currently led to the possibility of accessing learning contents from anywhere, at anytime and almost instantaneously. However, accessibility is not always the main objective in the design of educative applications, specifically to facilitate their adoption by disabled people. Different technologies have recently emerged to foster the accessibility of computers and new mobile devices favouring a more natural communication between the student and the developed educative systems. This paper describes innovative uses of multimodal dialog systems in education, with special emphasis in the advantages that they provide for creating inclusive applications and adapted to the students specific evolution.
Barcodes for closed one form - an alternative to Novikov theory

We extend the configurations discussed in Burghelea's book and Burghelea-Haller's paper on topology of angle-valued maps, equivalently the closed, open and closed-open bar codes from real- or angle-valued maps, to topological closed one forms on compact ANRs. As a consequence one provides an extension of the classical Novikov complex associated to a closed smooth one form and a vector field the form is Lyapunov for, to a considerably larger class of situations. We establish strong stability properties and Poincar\'e duality properties when the underlying space is a closed manifold. Applications to Geometry, Dynamics and Data Analysis are the targets of our research. A different approach towards such bar codes was proposed in Usher-Zhang's work.
Global Well-Posedness Of A Non-Local Burgers Equation: The Periodic Case

This paper is concerned with the study of a non-local Burgers equation for positive bounded periodic initial data. The equation reads $$ u_t - u |\nabla| u + |\nabla|(u^2) = 0. $$ We construct global classical solutions starting from smooth positive data, and global weak solutions starting from data in $L^\infty$. We show that any weak solution is instantaneously regularized into $C^\infty$. We also describe the long-time behavior of all solutions. Our methods follow several recent advances in the regularity theory of parabolic integro-differential equations.
An Extended Recommendation System using Data Mining Implemented for Smart Phones

In this paper we introduce a recommendation system that attempts to solve some of the issues of classical recommendation systems: the need for huge amounts of data to be able to extract meaningful patterns, or for directly visible connections between the users. We propose a rating method that is based on a hierarchical tag system used to describe the subjects of recommendation, and two data mining algorithms that run on the data gathered through this rating system.
Theoretical Study on Substituent's Effect on the Properties of Benzofused thieno (3, 2 - b ) Furan and its Isomeric Form

The theoretical study on the ground state properties of isomeric benzofused thieno(3,2 - b)furans was carried out using semi - emperical AM1 and Density functional theory/B3LYP 6 - 31G* /6 - 31G* basis set. This was used in order to determine the effect of substituent; Br 2 , I 2 , OH - , on the stability, reactivity and other properties of the isomers. From the calculated values of E , μ , η , ω, ΔH - L obtained, it can be inferred that thieno(3,2 - b )benzofuran is more aromatic, more stable and less reactive than isomeric benzothieno(3,2 - b )furan. These results agree with the experimental result concerning the different reactivity and stabil ity of both heterocyclic systems. The study of bond order uniformity, local ionization energy and electrostatic potential energy surfaces analysis revealed structural differences of isomeric thieno(3,2 - b )furans that explains their reactivity features. Benz othieno(3,2 - b )furan could be an analogue of aromatic benzothiophene substituted with C(2)=C(3) vinylic moiety. This evidently points out therefore that the electrophilic substitution reaction for benzothieno(3,2 - b )furan goes via addition - elimination mechan ism at the C(2). ( Isaiah A. Adejoro, Collins U.

SFB 823 Asymmetry and performance metrics for equity returns

An assumption of symmetric asset returns, together with globally risk averse utility functions, is unappealing for fund managers and other activist investors, whose preferences switch between risk aversion on the downside and risk seeking on the upside. A performance return criterion is originated that is more consistent with the implicit Friedman-Savage utility ordering. Adapted from recent developments in the income distribution literature, the proposed metric weights the lower versus upper conditional expected returns, while a dual spread or dispersion metric also exists. The resulting performance metric is easy to compute. A point of departure is the conventional Sharpe performance ratio, with the empirical comparisons extending to a range of existing performance criteria. In contrast, the proposed W-metric results in different and more embracing performance rankings.
Traction System Characteristics of Railway Vehicle

Recently, as the feasibility study shows that trans-Korea railway and trans-continental railway are advantageous, interest in high speed railway system is increasing. Because railway vehicle is environment-friendly and safe compared with airplane and ship, its market-sharing increases gradually. Korean High Speed Train has been developed by KRRI for last 7 years to satisfy the need. Korean High Speed Train (350km/h), composed of 2 power cars, 2 motorized car and 3 trailer cars, has been developed and is under trial test. To verify the design requirements for the functions and traction performances of the train, KRRI (Korea Railroad Research Institute) decided to evaluate traction performances of the train during trial test. For this purpose, torque, velocity, voltage and current must be measured. KRRI has developed a measurement system that can measure vast and various signals effectively. In this paper, we introduce traction performances of Korean High Speed Train. The traction measurement items are focused on the verification of motor block performances. Motor block consists of 2 motors. By this test, we verified traction performances of Korean High Speed Train
A New Perspective on the Large-scale Tidal Effect on the Galaxy Luminosity and Morphology

We study the mean tidal coherence of galaxy environments as a function of intrinsic luminosity determined by the absolute r-band magnitude. The tidal coherence of a galaxy environment is estimated as the cosine of the angle between two minor eigenvectors of the tidal field smoothed at the scales of 2 and 30 h−1 Mpc, respectively, centered on each of the local galaxies from the Sloan Digital Sky Data Release 10. Creating four luminosity-selected samples of the Sloan galaxies, we control them to have identical density distributions in order to nullify the dominant effect of the local density. The samples containing more luminous wall and field galaxies were found to yield lower mean values of the tidal coherence, which is a trend that turns out to be robust against the variation of the smoothing scales. At a fixed morphology, the same trend is found for the late-type spiral and lenticular galaxies in both of the field and wall environments. The early-type spiral field galaxies show no significant dependence on the tidal coherence, while both of the least and most luminous elliptical wall galaxies are found to dwell in the regions with highest tidal coherence.
The Redefinition of the SI: Impact on Calibration Services at NIST

Abstract: As most readers are probably at least vaguely aware, it is likely that the SI system of units will be redefined in 2018. This redefinition would fundamentally change the logical structure of the SI, with one result being a substantial change in how mass is realized and disseminated within national metrology institutes (NMI's) such as the National Institute of Standards and Technology (NIST). However, we expect that the only impact on how customers see calibration services will be small step changes that NIST will document and publicize to customers in advance. In this article, we list the main areas of calibration services at NIST, describe how for most of them there will be negligible impact, discuss the impact on mass and DC electrical calibrations, and explain our best predictions as to how we expect NIST to make a seamless transition for customers in those two areas.

Are there pheromonal dominance signals in the bumblebee Bombus hypnorum L (Hymenoptera, Apidae)?

Existe-t-il chez le bourdon Bombus hypnorum L (Hymenoptera, Apidae) des signaux pheromonaux de dominance? Nous avons identifie et compare les bouquets odorants de reines, de divers groupes de dominance d'ouvrieres et d'ouvrieres fraichement ecloses de Bombus hypnorum. Dans un premier temps le comportement individuel des ouvrieres de bourdons a ete observe, ce qui a permis de les classer en dominantes, subordonnees et butineuses. Par rapport aux ouvrieres subordonnees et aux butineuses, les ouvrieres dominantes se sont montrees plus agressives dans leurs interactions avec les autres ouvrieres (fig 1). Elles avaient des ovaires significativement plus gros (fig 2) et une tendance a avoir un corps gras developpe; en revanche les butineuses avaient les plus petits ovaires et un corps gras peu developpe. On a realise des extraits de glandes de Dufour (DG), des extraits de tetes (HE), des lavages de cuticules (CWS) et des echantillons de phase vapeur (HS) et identifie 132 composes (tableau I) par analyse en CG/MS (chromatographie phase gazeuse/spectrometrie de masse) et par la technique de co-injection. Les reines et les groupes d'ouvrieres ont presente des differences significatives, en fonction de leur comportement et de leur âge, dans la quantite totale de composes volatils et dans leurs proportions (fig 4, tableaux Il-V). Les quantites absolues de produits volatils etaient maximales chez les reines et plus elevees chez les ouvrieres dominantes que chez les subordonnees. De petites quantites ont pu etre detectees chez les butineuses et les quantites les plus faibles ont ete trouvees chez les ouvrieres fraichement ecloses. La meilleure discrimination des sous-groupes d'ouvrieres a ete obtenue par les profils volatils des extraits de tetes et des lavages de cuticules. Les ouvrieres dominantes et subordonnees presentent des profils tres proches l'un de l'autre mais nettement differents de ceux des reines, des butineuses et des ouvrieres fraichement ecloses. Les proportions relatives des alkanes ramifies dans les extraits de glandes de Dufour et de tetes sont plus elevees chez les abeilles dominantes que chez les autres ouvrieres. Les butineuses se differencient de tous les autres groupes d'ouvrieres par des proportions plus fortes d'acetates insatures et d'alkadienes dans les extraits de glandes de Dufour et dans les lavages de cuticules. Les bouquets odorants des reines se caracterisent par la proportion la plus elevee d'alkanes ramifies, d'alcools terpeniques et d'esters de cire et different significativement de ceux des ouvrieres. Les ouvrieres dominantes presentent un profil volatil semblable a celui des reines (fig 5). La discussion porte sur la signification biologique de ces resultats en relation avec l'hypothese actuelle de l'evolution des signaux pheromonaux de dominance chez les insectes sociaux.

Getting the message across biodiversity science and policy interfaces: A review

This contribution analyses the difficulties of biodiversity policy-making and the role of science. It addresses biodiversity scientists’ struggles to communicate the value of biodiversity to policy-makers, and the tensions between producing policyrelevant research and being perceived as too prescriptive. The author argues that it is important for biodiversity scientists to acknowledge and engage with the political aspects of biodiversity policies. A first step is to recognize the diversity of valuations and preferences among various stakeholders of different trade-offs, and the power relations between the stakeholders. A transparent presentation of a broad range of policy options, including an explic it description of the assumptions and models underpinning them, is a further requisite. Such presentations in turn require better understanding of the way institutions governing ecosystem (services) emerge and are established.
Optimal Portfolio Allocation based on two Novel Risk Measures and Genetic Algorithm

The problem of optimal portfolio selection has attracted a great attention in the finance and optimization field. The future stock price should be predicted in an acceptable precision, and a suitable model and criterion for risk and the expected return of the stock portfolio should be proposed in order to solve the optimization problem. In this paper, two new criterions for the risk of stock price prediction has been presented, of which the first one is based on the interval predictions which vary with time and proportional to the uncertainty of stock price data, while the second one is a constant risk term that is proportional to the prediction error variances of the neural networks. A novel cost function has been presented to simultaneously consider the expected returns and risks. Genetic algorithm has been used to solve this optimization problem. Finally, 18 shares of the Tehran Stock Exchange have been considered to evaluate the performance of the proposed risk criterions. Two proposed risk criteria, by the conditional value at risk (CVaR) associated with the same stock. The problem of stock portfolio optimization has been solved for all three situations, and the PI-based risk criteria yielded a better return
An area of exceptional land snail diversity: the MacLeay Valley, northeastern New South Wales

Stanisic, J., 1997. An area of exceptional land snail diversity: the Macleay Valley, north-eastern New South Wales. Memoirs of the Museum of Victoria 56(2): 441-448. In the Macleay Valley region, north-eastern New South Wales, the combination of rain-forest and limestone has provided a unique environment for the evolution of a quite remarkable land snail fauna. 108 native species have been recorded in an area approximately bounded by the Nambucca River in the north, the Hastings River in the south and the eastern escarpment of the Great Dividing Range in the west. Much of this diversity is centred on a series of limestone exposures which outcrop in an east-west direction from just west of Kempsey to the ranges ofthe Werrikimbc National Park. Diversity levels on the limestones are high with 39 species of land snails recorded at an outcrop near Yessabah. In contrast rainforest sites have smaller numbers of species. Comparatively few species inhabit the sclcrophyll forests. A number of species are endemic to the limestones and some of these exhibit specialised microhabitat preferences. This study examines the distribution of these species within the Macleay Valley region and elsewhere, and attempts to explain the development of this fauna in terms of past climate-induced changes in vegetation communities within the region. The implications of these findings for land snail conservation are discussed.
HISTOPATHOLOGICAL EVALUATION OF NON-ALCOHOLIC FATTY LIVER DISEASE: MINI-REVIEW OF LITERATURE

Non-alcoholic fatty liver disease (NAFLD) is a liver disease, which has common characteristics, as hepatic steatosis (lipid accumulation in hepatocytes) and fibrosis of the tissue. From these characteristics, the gold standard for diagnosis of the disease is the histopathological evaluation after liver biopsy. For this evaluation, some scores are available, and the SAF score (Steatosis, Activity, Fibrosis) has recently been described for a more complete assessment of the hepatic status. The purpose of this mini-review is to report the NAFLD using this new score.
Preparation and characterisation of vertically aligned single-walled carbon nanotube arrays on porous silicon

Vertically aligning carbon nanotubes (VACNTs) onto 2D porous materials is advantageous for many conceivable electronic applications but also for investigating the unique water transport properties of CNTs and the molecular separation of molecules during fluid transport through their inner shell. Here we report a wet chemical technique to produce vertically-aligned single walled CNT arrays on porous silicon (pSi). The nanotubes were first acid treated to produce carboxylic acid functionalities on the single-walled CNT. The carboxy-functional nanotubes were then covalently immobilised on a pSi surface that had been either ozone treated or silanated with aminopropyl triethoxysilane (APTES). The VACNT surfaces were analysed with atomic force microscopy (AFM), confocal Raman spectral imaging and Fourier transform infrared (FTIR) spectroscopy. Dense arrays of VACNTs were observed with the obtained CNT orientation and surface coverage depending upon attachment method and attachment reaction time.
