High single-cell metabolic activity in Antarctic sea ice bacteria

Antarctic sea ice bacteria have historically been examined by techniques that measure bulk community properties. In recognition of the complexity of microbial community structure and function, methods are now available to assess the physiological status of individual bacterial cells. We employed 3 assays: Nucleic Acid Double Staining (NADS), modified Vital Stain and Probe (mVSP) and 5-cyano-2, 3-ditolyl tetrazolium chloride (CTC) to (1) quantify the cell-specific metabolic status of bacteria present in the bottom of Antarctic fast-ice and (2) determine whether physiological probes can be used to quantify short-term changes in bacterial metabolic activity. Each assay was used in manipulative experiments ( 68% (NADS) and >95% (mVSP) of the post-incubation cell count. High cellular rRNA content was observed using fluorescence in situ hybridisation with an average of 80% of DAPI-stained cells hybridising with the general bacterial probe EUB338 (mVSP). An average of 32% of the bacterial cells were undergoing active respiration (CTC+) which is significantly higher than the 2 to 10% level of activity typical for most marine systems. The short-term effect of incubation irradiance or manipulation of microalgal photosynthate was not significant for any assay. Single-cell analysis of melted ice cores suggests that sea ice is among the most productive microbial habitats, while CTC is favoured for establishing a real-time bacterial response in the sea ice ecosystem. © Inter-Research 2008.
The Diluted Economics of Casinos and Crime: A Rejoinder to Grinols and Mustardâ€™s Reply

In their reply to my comment (Walker 2008) Grinols and Mustard explained that in their original study (2006) their interest was â€œin the costs to the host county associated with a change in crime from whatever sourceâ€ (Grinols and Mustard 2008, p. 22). In this rejoinder, I explain that the estimated costs of crime attributable to casinos will be overstated if the estimated crime effects are based on the â€œundilutedâ€ crime rate used by Grinols and Mustard (2006). I also discuss why this issue is important, in the context of â€œsocial cost of casino gamblingâ€ estimates that are frequently quoted in political debate and by the media.
QUID 2017, pp. 2767-2774, Special Issue N°1- ISSN: 1692-343X, Medellín-Colombia THE IMPACT OF SOCIAL COMMERCE FEATURES ON CUSTOMER TRUST AND TENDECIES

Today, the growth and expansion of the Internet has led to the development of social networking sites and the subject of trade in social networks. Social commerce is a subset of e-commerce that social networking sites use for social interaction and user contributions to facilitate the online purchase and sale of diverse products and services. Consumer trust is a major factor in the success of corporate social business executives, so these companies need do a lot of work to be trusted. In this research, key factors in social commerce such as reputation, size, quality of information, communication, security of transactions and oral references, as well as the impact of trust on trust performance (buying tendencies and oral preferences) have been investigated. Validity and reliability of the questionnaire used in this research has been confirmed in the form of three methods of face, convergent and divergent validity, and the reliability of the tool is also used through two methods of Cronbach's alpha coefficient which was greater than 0.7 and a Split Half validation. The current research has been implemented at YAATAA Company, which allows its customers to purchase foreign sites such as Amazon and eBay. Empirical analysis based on a sample of 380 users and structural equation modeling with Amos software has been identified that all features of social commerce (with the exception of size and size) have a significant impact on trust and trust also has a significant impact on buying tendency and oral tendencies.
A simple test method for rapid measurement of fines content in soils

Visual soil classification methods used for estimating fines content are often relied upon in geotechnical investigations. The estimations of these methods are highly judgmental, generally erratic, and typically necessitate a confirmation. Laboratory mass-based wash tests are regularly performed on selected soil samples in order to verify or complement in situ visual classifications. Therefore, there is a dire need to improve the accuracy of fines content estimates of the visual methods. A preliminary study was conducted to assess the principle of estimating fines content by measuring relative volumes of the coarse-grained to fine-grained soil fractions. The results indicated soundness and adequacy of the principle. Utilizing this volume-based concept and the standard sample washing methods, a pilot study was conducted to develop and evaluate a more precise testing method, the mold test. Triplicate test runs were carried out on 144 soil samples. With run times of 5 to 15 min, the test is sufficiently rapid. The estimated fines contents of the samples were compared with that determined by the ASTM D1140 test. The absolute differences between the two estimates fell within 65 % range, which is an appreciably higher accuracy than those of commonly used visual soil classification methods. Analysis performed on the results of the pilot study attested statistical competences of the proposed test method. This study has proven that the mold test is convenient for measuring fines content in soils at almost no cost—except minor consumables. The test method eliminates the subjectivity associated with current visual classification tests as well as the time and cost of the standard laboratory wash tests. While it is not intended to be a substitute for the latter, the mold test is an economically viable option that maintains balance between laboratory accuracy and practicality of the field methods.
Enhancement of critical current density in superconducting wires NbTi

The research that was done has proven that it is possible to enhancement Jc in NbTi wires, by means of cold drawing of the wire (wire drawing machine). We believe that it is a vital piece of information particularly for those institutions that possess NbTi wires and superconducting NbTi magnets. Cold drawing of the wire does not decrease critical temperature and critical magnetic field of the wire. Streszczenie. W artykule przedstawimy wyniki pomiarow Jc w drucie NbTi.

Effect of Temperature on Diffusion Parameters for 2-DimensionalCopper 5-Atom Island

The effect of temperature during the diffusion of Cu pentamer on Ag(111) surface has been studied by using molecular dynamics (MD) technique at 300, 500 and 700 K. The diffusion coefficient, effective energy barrier and diffusion prefactor for Cu pentamer on Ag(111) have been calculated. The effective energy barrier of 205.25 ± 10 meV and diffusion prefactor of 5.549 × 1012 A2/s have been deduced from the Arrhenius plot. The semi-empirical potentials based on MD simulation shows that the diffusivity obeys the Arrhenius Law and is independent of temperature from 300 to 700 K. The pop-up of single-atom among Cu pentamer has also been observed at 700 K. The value of effective energy barrier is in close agreement with that found from early Monte Carlo simulation.

CPW-fed to CPS Dipole Antenna of Microstrip Tapered Balun with Triangular Loop Director

A CPW-fed to CPS dipole antenna of triangular loop director by microstrip tapered balun is proposed for dual and wide band operations, in this paper. The proposed antenna is consisted of a CPW-fed to CPS transform, microstrip tapered balun element, CPS dipole driver and triangular loop director. A dual and wide bandwidth of the proposed dipole antenna is realized by introducing the triangular loop director and taper matching element. The operated frequency bandwidth is 1GHz (2.14~3.14 GHz) and 1.9 GHz (4.6~6.5 GHz) to return loss criterion of less than 10 dB. The measured return loss of the proposed antenna showed good results of the dual and wide band operating frequency and the radiation pattern. The proposed antenna is able to support WLAN wireless communications applications.
Word Power: A New Approach for Content Analysis

We present a new approach for content analysis to quantify document tone. We find a significant relation between our measure of the tone of 10-Ks and market reaction for both negative and positive words. We also find that the appropriate choice of term weighting in content analysis is at least as important as, and perhaps more important than, a complete and accurate compilation of the word list. Furthermore, we show that our approach circumvents the need to subjectively partition words into positive and negative word lists. Our approach reliably quantifies the tone of IPO prospectuses as well, and we find that the document score is negatively related to IPO underpricing.
Sketch image recognition using deep features

Sketch is a special group of images, and the ability to recognize sketches is of great importance for many applications, including the human-computer interaction and childhood education. Previous approaches often pose this as a sub-class of general image classification which can be solved with a conventional pattern recognition method. In this thesis, instead of applying general image classification methods directly to sketches, a model using a new deep neural network that considers more of the unique characteristics of sketches has been developed and studied. Experiment results on the challenging sketch datasets demonstrate the superior performance of this present model in comparison to previous state-of-the-art methods. In addition to a novel method for sketch image classification, the topic has been further expanded to enable the matching of face sketches to photo images. This is of critical significance, especially in the law enforcement area to identify criminals. Previous work has attempted to address this task by exploring invariant features or looking for a shared subspace. In this paper, an end-to-end method has been proposed whereby the similarity score can be obtained directly when inputting a pair of sketch and photo-face images. In particular, this study investigates matching image pairs with more diversity than previous studies, considering such features as the presence of a beard, or haircut style, etc. The approach taken in this study is one utilizing a CNN based model, which is more robust and applicable to the complexities existing in the real world. The method presented exhibits good performance with both forensic sketch dataset and viewed sketches. Furthermore, in this study, the largest face sketch dataset has been created which can accommodate, in total, 14750 positive pairs and 985512 negative pairs for evaluation, which will facilitate future research.
Local Search for Unsatisfiable Propositional Formulae

Stochastic local search (SLS) has been an active field of research in the last few years, with new techniques and procedures being developed at an astonishing rate. SLS has been traditionally associated with satisfiability solving, that is, finding solutions for a set of problems. However, their intrinsic nature does not allow them to address unsatisfiable problems. Selman, Kautz and McAllester proposed a challenge to use local search instead to prove unsatisfiability. In this document we give an extensive overview on how to improve the state of the art SLS unsatisfiability solver RANGER using GUNSAT’s techniques, namely unit propagation look-ahead and extended resolution.
Word Sense Disambiguation Based On Global Co-Occurrence Information Using Non-Negative Matrix Factorization

In this paper, I propose a novel word sense disambiguation method based on global co-occurrence information using Non-negative Matrix Factorization (NMF). When I calculate the dependency relation matrix, the existing method tends to produce very sparse co-occurrence matrix from a small training set. Therefore, the NMF algorithm sometimes does not converge to desired solutions. To obtain a large number of cooccurrence relations, I propose to use co-occurrence frequencies of dependency relations between word features in the whole training set. This enables us to solve data sparseness problem and induce more effective latent features. To evaluate the efficiency of the method of word sense disambiguation, I make some experiments to compare with the result of the two baseline methods. The results of the experiments show this method is effective for word sense disambiguation in comparison with the all baseline methods. Moreover, the proposed method is effective for obtaining a stable effect by analyzing the global co-occurrence information. 2 Keywords
Does Recent Regulation Improve (or not) the Spanish Mutual Guarantee System

This paper aims to analyse the new regulation framework and its impact on the Spanish mutual guarantee system (MGS), especially on the cost of the guarantee. The main conclusions are that the reforms which were introduced do not directly affect the reduction of this guarantee cost. Nevertheless, in our opinion, the regulation has strengthened the mutual guarantee system during the crisis as a result of the banks generating confidence to this financial intermediary, which helps to correct credit market failures. Currently, banks are more likely to recognize the role of the mutual guatentee society (MGS) and the declining risk involved thanks to the guarantee offered by the MGS that exhibits stronger solvency, liquidity and good governance policies.
Combining ability analysis and evaluation of heterosis in Jatropha curcas L . F 1-Hybrids

With the aim of estimating genetic parameters and recognizing superior Jatropha curcas L.combinations, ten superior plants were selected based on seed yield and oil content, and were crossed among them in a 10 x 10 half-diallel mating design to produce 45 F1hybrids. The experiment was conducted in nursery stage using a randomized complete block design (RCBD) with three replications. Analysis of variance for the combining ability indicated that GCA and SCA variance were significant at 1% probability for plant height, collar diameter and number of leaves in nursery stage. The low ratio of GCA/SCA exhibited the non-additive effects. Broad sense heritabilies were high for plant height, collar diameter and number of leaves. Estimates for narrow sense heritability of the traits, plant height collar diameter and number of leaves were low. Percentages of heterosis and heterobeltiosis values for plant height, collar diameter and number of leaves ranged from negative to positive. This showed that the existence of dominance or nonadditive gene actions might be present in the hybrids. On the basis GCA and SCA effects, parents, Ph1.2 and In2.1 and hybrids Ph1.2 (3) × In1.2 (8), Ph1.1 (9) × My2.2 (10) and My2.1 (1)× My2.2 (10) could be used for future breeding program.
Agent based decision support systems in medicine

Embedding Machine Learning technology into Agent Driven Diagnosis Systems adds a new potential to the realm of Medicine, and in particular to the imagiology one. However, despite all the research done in the last years on the development of new methodologies for problem solving, in terms of the design of MultiAgent Systems (MAS) there is none where both the agent and the organizational view can be modelled. Current multiagent approaches to problem solving either take a centralist, static approach to organizational design or take an emergent view in which agent interactions are not pre-determined, thus making it impossible to make any predictions on the behavior of the whole systems. Most of them also lack a model of the norms in the environment that should rule the behaviour of the agent society as a whole and/or the actions of the individuals. In this paper, it is proposed not only a framework for modelling and run agent organizations, but also to depict the different components of such societies. To illustrate these premises, we will evoke a society with one modality, the Axial Computed Tomography one, where two different but complementary computational paradigms, the Artificial Neural Networks and the Case Based Reasoning are object of attention.
Hematological profile of healthy Pantaneiro horses

Pantaneiro horse is small in size (averaging= 137.7cm), docile, and rustic, having characteristics developed over the course of four centuries of natural selection in the Pantanal region of Mato Grosso, Brazil (Beck, 1985; Santos et al., 1995; Miserani et al., 2002). They are descendents of Andalucian and Lusitano horses of the Iberian peninsula (Cothran et al., 1998). The characteristics of Pantaneiro horses differ from those of other breeds due the need to adapt to the Pantanal environment. During its evolution, the Pantaneiro horse lost its aesthetic beauty and took advantage of zootechnical characteristics targeted for function. It developed a straight and tall frame, similar to that of a mule, conferring a tolerance to immersion in water for prolonged periods. Historically, this breed is used for working (e.g., cattle handling); however, currently, it is also being used for sporting due to notable physical capacity (Beck, 1985; Santos et al., 1995).
Identification of Molecular Marker Based on MYB Transcription Factor for the Selection of Indonesian Fine Cacao (Theobroma cacao L.)

Indonesia is the third largest cacao (Theobroma cacao L.) producer in the world and also well-known for its fine cacao varieties (Java fine-flavor cacao). Indonesian fine cacao breeding program will be accelerated by early detection of its specific trait through the use of molecular marker. One of the traits thatcould differentiate fine and bulk cacao, in this case Criollo and Forastero, respectively, is the pod color. Previous research reported that MYB transcription factor gene regulated cacao pod color and was able to differentiate Criollo from Forastero. The gene involved in the control of plant-specific processes including primary and secondary metabolism, cell fate and identity, developmental processes and responses to biotic and abiotic stresses. This research aimed to identify the diversity of Indonesian fine and bulk cacao based on MYB nucleotide sequence fragments. Identification of the MYB nucleotide sequence was conducted by DNA isolation from cacao leaves and specific primer design based on two cacao MYB transcription factor ene accessions. These primers were used to evaluate the diversity of three Indonesian fine cacao (DRC 16, PNT 16, and ICCRI 01) and two bulk cacao (PA 191 and ICCRI 03) clones. The cluster analysis showed that this specific primer is similar to other MYB gene accessions in Malvaceae family (Theobroma, Herrania, Gossypium). It is also able to differentiate bulk and fine cacao in accordance to their pedigree. The primer developed in this study could be used for further analysis of Indonesian fine cacao molecular marker.
Inclusive Education and ELT Policies in Colombia: Views From Some PROFILE Journal Authors

This article reports on a study aimed at exploring inclusive policies in the teaching of English as a foreign language in Colombia, as evidenced in the articles published in the PROFILE Journal by Colombian authors. The use of the documentary research method and critical discourse analysis showed that some policies—mainly The National Program of Bilingualism and the Basic Standards for Competences in English as a Foreign Language—contain issues closely related to the logic of discriminatory and segregation attitudes in English language teaching. We hope that the results of our analysis will generate more interest in scholars to examine language policies and work further to eradicate inequalities in education.
Adults and Elders and their use of ICTs. Media Competence of Digital Immigrants

The undisputed presence of Information and Communication Technologies (ICTs) in our lives has led to the development of new forms of social, interactive and critical relationships. This study aims to compare the level of media competencies, in relation to six established categories, of two population groups: adults (aged 18-55) and elders (aged over 55). The sample was composed of 714 people from the eight provinces making up the Spanish region of Andalusia. The study conducted was based on the selection and comparison of results of specific items drawn from two separate questionnaires, directed to both population groups. The data were statistically processed in accordance with the distribution of the sample proportions. The objective was to identify and contrast the degree of digital literacy of these two groups, in terms of their use, productivity and interaction with technological tools. The results highlight the needs and demands of both groups in terms of technology, critical reading and audio-visual production. It is notable that adults aged 18 to 30 have a higher level of expertise in the interaction and language dimensions, while those aged 30 and above perform better in critical and participative dimensions offered by such media, such as reflection, analysis and creation. In the over-55 group, there is a direct correlation between income bracket and level of media skills, the latter significantly diminishing with age.
Efficient Removal of Toxic Textile Dyes using Silver Nanocomposites

In the present study biomimetic synthesis of silver nanoparticles using Solanum nigrum and Cannabis sativa were explored. The biosynthesized silver nanocomposites were characterized using UV-VIS spectroscopy, DLS, TEM, FTIR and XRD. The characteristic surface plasmon resonance of Solanum nigrum and Cannabis sativa were recorded at 430 and 445 nm respectively. The average diameter of silver nanocomposites were 34.13 ± 3.10 and 70.93 ± 3.57 nm for Solanum nigrum and Cannabis sativa leaf extract respectively. The release of textile dyes into our surrounding water bodies has toxic effect on human health and marine life therefore removal of these dyes is necessary to protect environment. The nanotechnology has provided a new platform for waste water treatment. Hence the biosynthesized nanocomposites were employed for dye removal from wastewater. The effects of various parameters, such as time of incubation, concentration, pH, and temperature, were studied. The biosynthesized silver nanoparticles are most effective in dye removal at alkaline pH 9 and at 60oC. The textile industry effluents have high pH and temperature which makes these nanoparticles more appropriate in treatment of these industry effluents. To elucidate the reusability, the decolorizing efficiency of biosynthesized silver nanocomposites were investigated upto 3 cycles.
