Molecular biological characteristics : common and different profiles between the dental pulp stem cells and periodontal ligament stem cells

Dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PDLSCs) are two most common dental stem cell resources for tissue engineering or stem cell therapy for many conditions. However, the molecular biological characteristics of DPSCs and PDLSCs are still unclear. In this study, we tried to explore the common and different profiles of molecular characteristics between the DPSCs and PDLSCs based on the analysis of geneexpression microarray data from Gene Expression Omnibus (GEO) database using database for annotation, visualization and integrated discovery (DAVID). The results showed that many differentially expressed genes between the human DPSCs and PDLSCs were related to neural system, skeleton system, teeth and cardiovascular system development. The different molecular expression patterns between the DPSCs and PDLSCs also implied that DPSCs may be more suitable cell resources for the treatment of neural, cardiovascular and odontogenesis related disease, whereas PDLSCs may be more suitable cell resources for the treatment of periodontal ligament, cementum and alveolar bone related disease.
DEVELOPMENT OF JAMUN SYNBIOTIC SMOOTHIE

In the present study smoothie was prepared using different inclusion levels of jamun and yoghurt. The inclusion level of jamun: yoghurt ratio at 20:80 (JS3) per cent was found optimum by sensory analysis. Jamun juice exerted maximum prebiotic effect on L.plantarum. L.plantarum was examined for its probiotic properties, microencapsulated in jamun juice and incorporated into smoothie to make it synbiotic.Shelf life studies (7days) of the synbiotic smoothie included analysis of physicochemical, functional, microbial and sensory characteristics. The range of total phenolic content (TPC), antioxidant activity and ascorbic acid was from 19.23 to 19. 80μg/mg; 56.06 to 56.07mgFe 2+ /100ml and 0.80to 0.74mg/100ml during 1 to 7 days of storage respectively. Coliform, yeast and mould count were not detected during storage at refrigerated temperature in the synbiotic smoothie.
C Risk Factors for Reoperation in Patients Treated Surgically for Degenerative Spondylolisthesis

recurrent stenosis or progressive spondylolisthesis (45%), compliStudy Design. Retrospective analysis of prospective data from the degenerative spondylolisthesis (DS) arm of the Spine Patient Outcomes Research Trial. Objective. The aim of this study was to identify risk factors for reoperation in patients treated surgically for DS and compare outcomes between patients who underwent reoperation with nonreoperative patients. Summary of Background Data. Several studies have examined outcomes following surgery for DS, but few have identified risk factors for reoperation. Methods. Analysis included patients with neurogenic claudication (>12 weeks), clinical neurological signs, spinal stenosis, and DS on standing lateral x-rays. Univariate and multivariate analyses were used to investigate patient characteristics and risk factors. Treatment effects (TEs) were calculated and compared between study groups. Results. Of 406 patients, 72% underwent instrumented fusion, 21% noninstrumented fusion, and 7% decompression alone. At 8 years, the reoperation rate was 22%, of which 28% occurred within 1 year, 54% within 2 years, 70% within 4 years, and 86% within 6 years. The reasons for reoperation included
The potential of GMES satellite data for mapping nitrogen dioxide at the European scale

The potential of future satellite retrievals of NO2 as collected within the Global Monitoring for Environment and Security (GMES) initative for purposes of European-scale mapping of air quality is assessed. After comparing several existing NO2 datasets from different instruments with respect to their suitability for simulating Sentinel-5 precursor data in the mapping procedure, the daily 0.1 degree resolution OMNO2e dataset produced by the National Aeronautics and Space Administration (NASA) was selected for further processing. Annual mean station data for 2009 was combined with the satellite NO2 data as an auxiliary variable using geostatistical techniques. More specifically, residual kriging was used. The results were compared to an equivalent approach using highresolution model output as an auxiliary dataset. The results indicate that satellite data giving NO2 tropospheric columns at a spatial resolution of approximately 10 km × 10 km provide significant improvements in mapping accuracy as compared to geostatistical interpolation of solely station data. While not quite reaching the accuracy level of using high-resolution model output as an auxiliary dataset, satellite-based tropospheric column data of NO2 is shown to be a suitable proxy for obtaining spatial information for mapping purposes, when such highlydetailed model data is not available as is often the case due to the high demands on computational resources.
Comparative Analysis of Selected Classifiers in Mining Students' Educational Data

Educational data mining is concerned with developing methods that discover knowledge from educational databases. Many predictive classifiers have been applied in mining educational data with less emphasis on their performance evaluation in order to determine the most efficient. In this study, a comparative analysis of three predictive classifiers for mining educational data was conducted.

ESTIMATION OF HIGH-FREQUENCY WAVE RADIATION AREAS ON THE FAULT PLANE OF THE 1994 SANRIKU-HARUKA-OKI EARTHQUAKE

We investigated the high-frequency wave radiation process of the 1994 Sanriku-Haruka-Oki earthquake (Mw = 7.7) and the accumulated tectonic stress on the source region. The rupture process was estimated from an envelope inversion of acceleration seismograms. The large highfrequency waves were radiated at the edges of the fault plane and at the near edges of the large slipped areas. This result suggests that stopping of rupture causes the high-frequency wave radiation. The accumulated tectonic stress on the fault plane in a time interval was calculated with a 2-D finite element model. The distribution pattern of accumulated stress on the western part of the fault plane is similar to that of slip. One of the possible explanations of the result is that the asperities on the western fault plane are characteristic asperities. From the comparison with the distributions of accumulated stress and high-frequency wave radiation intensity, it is indicated that the spatial variation in accumulated stress in the area of asperity affects the intensity of highfrequency wave radiation.
Publics , Campaigns , and Political Knowledge

Building on the growing body of research on campaign learning, this paper considers the way that learning about policy issues depends on the nature of the issue and its relevance for the individual citizen. Specifically, the analysis finds that seniors learned much more than non-seniors about candidate positions on an emerging Social Security issue that was heavily emphasized in the 2000 campaign, but not when the same issue was more familiar and largely ignored by the candidates and press in the 2004 campaign. Yet, even without additional learning or campaign emphasis, seniors still knew more than non-seniors in the later contest. These results suggest that once party positions become familiar to them, issue publics will hold their information advantage across future elections without dependence on further campaign emphasis.
STRUCTURE OF LESS SIMPLE LIQUID ALLOYS : Ag

The transferabil ity of the local evanescent core (EC) pseudopotential to less-simple liquid binary alloys is assessed. The structural properties of liquid Ag-In alloys at different compositions are calculated using the Variational Modified Hypernetted Chain (VMHNC) integral equation theory of liquids with the effective pair potentials derived from the evanescent core electron-ion potential constructed by Nogueira, Fiolhais and Perdew for the solid state. Comparison with the results those obtained by other different forms of the model pseudopotentials and experimental data confirms the ability of the universal density dependent version of the EC potential to be used in the case of liquid less-simple metals and metal alloys.
How people write together (groupware)

Builders of groupware writing technologies need a better understanding of collaborative writing if their systems are to adequately address user needs. The authors present a taxonomy of joint writing based on an analysis of interviews with authors who have written documents together. The taxonomy describes joint writing in terms of four components: roles played in the collaboration, activities performed in the writing process, document control methods used, and writing strategies employed. The authors conclude by outlining a set of design requirements for collaborative writing that are suggested by the interviews and the taxonomy, and by evaluating six existing systems with respect to these requirements. <<ETX>>
IN VITRO SHOOT INDUCTION OF THREE GRAPE ( VITISVINIFERA L . ) VARIETIES USING NODAL AND AXILLARY EXPLANTS

Grape (Vitisvinifera L.) is a perennial, deciduous, woody vine cultivated in the tropical, sub-tropical and temperate regions of the world.Propagation by conventional means is restricted to a particular season and is dependent on availability of planting material.Conventional asexual propagation methods are difficult due to the long juvenility, greater time taken and plant material requirement for propagation and seasondependency (Jaiswal and Amin, 1992). Grapevine is conventionally propagated using dormant hardwood cuttings (36 to 46cm long), collected from well-developed current season’s canes during the winter (Thomas, 2001). These are planted in the nursery during spring, and one season’s growth gives plants for transplanting to the vineyard (Hartmann et al., 1997). This is a season-bound and slow process. Nonconventional propagation methods,viz., plant tissue culture, has emerged as a powerful tool for propagation and improvement which is adopted as an established method for commercial propagation under limited space, time and controlled conditions throughout the year, An added advantage is the ability to produce disease-free planting material under aseptic conditions. In micro propagation of the grape,the degree of response is highly dependent on genotype, as, various Vitis species/ cultivars/ hybrids respond differently to specific culture conditions (Qiu et al., 2004). Hence, there is an acute need to develop a protocol for shoot induction in different varieties and for studying the response of different explants for micro propagation for commercial propagation,entailing limited time and space. Mhatre et al. (2000)used nodal-bud cuttings bearing a single axillary bud, from three cultivars viz., Thompson Seedless, Sonaka and Tas-e-Ganesh, to initiate shoot cultures on G16 medium containing adenine sulphate, monobasic sodium phosphate, BAP and NAA, and developed a turf of multiple shoots.In vitro propagation of Vitis offers opportunities for increasing plant material available for cultivation. Cultures were established and maintained in vitro on MS medium, better shooting and shoot proliferation (80%) was obtained by subculture of micro cuttings on MS medium supplemented with 5μM BA (Jaskani et al., 2008) in‘Muscat of Alexandria’ cv. from shoot tips and internode segments. Maximum rate of shoot proliferation was obtained on MS medium containing 3.0mg/l BAP + 0.2mg/l NAA (Abido et al., 2013). Therefore, the present investigation was undertaken on micro propagation of three important cultivars of Vitisvinifera L. , viz., Crimson Seedless, Bangalore Blue and Red Globe, using axillary-bud and nodal-bud cuttings as explants, with an objective of identifying a suitable explant type and variety for in vitro shoot induction.
Beyond Story-Telling : Designing Case Study Research in International Environmental Policy

Scholars have employed a range of methods to explore international environmental politics and policy (IEP). A small, but increasing, number have approached the subject quantitatively (Sprinz and Vaahtoranta 1994; Underdal 2001; Mitchell 2002a). Most, however, have used qualitative methods. In doing so, they have varied in whether their goals are descriptive (what did happen? ), predictive (what will happen? ), normative (what should happen? ), or explanatory (what made this happen? ). Like the rest of the international relations community, IEP scholars also vary in theoretical proclivities, ranging along the constructivist-rationalist continuum (Ruggie 1998). Scholars’ different goals and proclivities have also led to debates about what qualitative research can, and should try to, accomplish. These debates are unlikely to be resolved soon, nor do we aspire to do so here. We believe that IEP scholars are more likely to understand the complexities of IEP accurately and fully if they use, as a community if not as individuals, a range of methods. Our goal is to aid those IEP students and scholars who, at least some of the time, use qualitative methods to pursue explanatory goals within a rationalist paradigm. Descriptive analyses of existing international environmental issues, processes, negotiations, or agreements and prescriptive analyses of alternative policies clearly play important political and intellectual roles in IEP. Our argument is limited to noting that they usually contribute little to our understanding of causal relationships. For ease of expo-
Characteristic features of research article titles in computer science

Previous researchers have given conflicting views as to what makes a "good" research article (RA) title. In this paper, characteristic features of research article titles, including length, punctuation usage, word frequency, and preposition usage are investigated using a corpus of 600 research articles from the six journals of the IEEE Computer Society. Results show, while some of the intuitive observations made in the literature about title writing are accurate for computer science journals, other observations have ignored the effects of discipline and field variation. Subsequently, these observations are either unjustified or misleading.
Multicompetence in L 2 Language Play : A Longitudinal Case Study

Humor and language play have been recognized as important aspects of second language (L2) development. Qualitative studies that have documented the forms and functions of language play for adult and child L2 users have taken place largely in classroom settings. In order to gain a fuller understanding of such creative manipulations by L2 users, it is necessary to examine these phenomena across a variety of contexts. In this article, we explore the ways that two L2 users marshal resources to play with language across communicative activities, for various purposes, and with a variety of interlocutors in interaction. Our goal is to gain a fuller view of our participants as multicompetent language users, specifically with respect to their playful communicative repertoires. The data consist of informal conversations which were recorded approximately every 2 weeks over 10–12 months. Episodes framed by the participants as playful were identified across all recordings and were analyzed qualitatively to document patterns of use and participation. Despite individual differences in style, both participants demonstrated sensitivity to context in their use of language play and an awareness of the ways humor functions as a social practice, subtly adjusting their strategies to changing social situations.
Microscopic characterization of palladium electrodes for cold fusion experiments

Recent results [1] highlighted that material science is one of the more critical issues in condensed matter nuclear science. In the last years, the experimental results have given a clear indication that a relevant role within this task is played by the material properties of the cathodes. In order to improve the characterization of the materials, an approach based on the atomic force microscopy is proposed in this paper. The preliminary study is mainly oriented to identify, by means of the AFM results, parameters suitable for screening the materials.
Empirical acquisition of conceptual distinctions via dictionary definitions

This thesis discusses the automatic acquisition of conceptual distinctions using empirical methods, with an emphasis on semantic relations. The goal is to improve semantic lexicons for computational linguistics, but the work can be applied to general-purpose knowledge bases as well. The approach is to analyze dictionary definitions to extract the distinguishing information (i.e., differentia) for concepts relative to their sibling concepts. A two-step process is employed to decouple the definition parsing from the disambiguation of the syntactic relations into the underlying semantic ones. Previous approaches tend to combine these steps through pattern matching geared to particular types of relations. In contrast, here a broad-coverage parser is first used to determine the syntactic relationships, and then statistical classification techniques are used to disambiguate the relationships into their underlying semantics. There are several contributions of this thesis. First, it introduces an empirical methodology for the extraction and disambiguation of semantic relations from dictionary definitions. Second, it introduces a statistical representation for these semantic relations using Bayesian networks, which are popular in artificial intelligence for representing probabilistic dependencies. Third, it shows how improvements in word-sense disambiguation can be achieved by augmenting a standard statistical classifier approach with a probabilistic spreading-activation system using the semantic information extracted using this process.
Estimation of Variance of Time to Recruitment for a Single Grade Manpower System Under Two Sources of Depletion Using Univariate Policy of Recruitment

In this paper a marketing organization consisting of one grade with policy and transfer decisions forming two sources of depletion is considered. The problem of time to recruitment for this organization is analyzed when the breakdown threshold for the cumulative loss of manpower, a level of maximum allowable manpower depletion, have single component as the exponential threshold. A mathematical model is constructed and using univariate policy of recruitment based on the shock model approach, analytical results are obtained for the variance of time to recruitment by assuming that the loss in man power, inter-policy and intertransfer decision times form three different sequences of independent and non-identically distributed exponential random variables.

TOWARDS OVERCOMING NEGATIVE GP ATTITUDES CONCERNING HEALTH INFORMATICS SYSTEMS

This paper reports on the attitudes of 23 South Australian General Practitioners (GPs) towards adopting Health Informatics (HI) technology. The qualitative study suggests attitudes are determined by contextual GP perceptions of competing managerial, technological and political factors. Findings indicate increasing exposure to HI use in performance of their role influences GP perceptions of the importance and certainty of implementation outcomes in different healthcare delivery contexts. Behaviour at the prospect of change perceived as uncertain, involuntary or not of demonstrable benefit to patients, tends to manifest as resistance. The findings highlight the desirability of potential HI technology use in a particular healthcare context being associated with benefits to the GP patients and practice rather than diminution of GP control over change to their role and value.
THE MEDITERRANEAN SEA : A NATURAL LABORATORY TO STUDY GAS HYDRATE DYNAMICS ?

Gas hydrates have been proven by coring at one site in the (eastern) Mediterranean Sea, but their wider extent remains uncertain. Here we present results from investigations of the potential Mediterranean gas hydrate system, suggesting that clathrates occur more widely and have been strongly impacted by glacial-interglacial climate forcing. Modeling of the methane hydrate stability zone (MHSZ) shows it to be present in most of the Mediterranean Sea, albeit in deep waters (>1000 m) due to warm bottom waters (12.5-14°C) and in greater thicknesses (200-500 m) in the geothermally cooler eastern basin. Comparison of the MHSZ with known or possible zones of gas flux to seabed suggests prospective areas for hydrate occurrence, mainly in the eastern basin. One is the Nile fan, where evidence of the first BSR in the Mediterranean Sea (presented sseparately, Praeg et al. this volume) confirms the potential for additional hydrate discoveries. During glacial stages, gas hydrate stability in the Mediterranean increased due to bottom waters up to 4°C cooler; even allowing for sea levels 125 m lower, the modeled glacial-stage MHSZ was up to 25% thicker and 300 m shallower on basin margins. Glacial-to-interglacial transitions thus corresponded to a marked reduction in hydrate stability, with downslope migration of the upper limit of the MHSZ across depths of c. 700-1000 m. A compilation of submarine landslides in the Mediterranean Sea indicates a peak in the age of slide deposits during the last deglaciation and includes abundant headwalls in midto upper slope depths (<1200 m), including on the Nile fan. Together these results suggest that the Mediterranean Sea, in particular its gas-rich eastern basin, offers natural laboratory conditions to test the hypothetical linkages between climate-driven changes in gas hydrate stability and slope instabilities over glacial-interglacial timescales.
A new gene for gall midge resistance in rice variety MR 1523

The Asian rice gall midge Orseolia oryzae (Wood-Manson) is a serious pest of rice in certain regions of south, central and east India causing significant yield loss mainly during kharif season. Breeding rice varieties with pest resistance has been a viable, ecologically acceptable approach for the management of the gall midge. However, rapid development of virulent biotypes capable of overcoming the host plant resistance has been posing problem in recent years. Systematic germplasm evaluation has led to the identification of important sources of resistance like Eswarakora, Ptb18, Ptb21, Siam29, Leuang152 etc. (see, Bentur et al., 2003) which have been extensively used in breeding resistant varieties. Genetic studies have identified, so far, 10 major genes conferring resistance (Kumar et al., 2005). Most of the 60 plus gall midge resistant rice varieties developed to date contain one of the three major genes viz., Gm1, Gm2 and an unidentified gene(s) in Ptb21 conferring immune level of resistance. Seven distinct gall midge biotypes have been characterized so far (Vijaya Lakshmi et al., 2006), some of them being selected as direct consequence of extensive cultivation of these varieties. In most of the studies, resistance to gall midge has been found to be conferred by a single dominant or (as in case of gm3) a recessive gene (Kumar et al., 2005). Exceptionally, sources deriving resistance from Ptb18 and Ptb21 have displayed complex pattern of inheritance of resistance (Kalode and Bentur, 1989). The rice variety MR1523 derives its gall midge resistance from Ptb18 & Ptb21 which have contributed resistance in 25% of the released varieties. But genetics of resistance in this breeding line has not been studied. This paper attempts to note inheritance of gall midge resistance in MR1523 and we note that possibly a new gene present in this variety confers resistance against gall midge biotype 4.
